# Agent Notes

One kind of design doc lives here. An **Agent Note** records a decision or proposal that shapes this codebase — the *why* and *what we gave up*, the parts code and docs can't carry. This file is the front door and contract: where Agent Notes live, when to write one, and [the in-file format](#the-file-format).

Every non-trivial change MUST add or update at least one Agent Note in the same PR. A change is non-trivial when it alters behavior, architecture, a cross-file or cross-package contract, process or tooling, testing strategy, an on-disk, wire, or configuration format, or another decision a maintainer may reasonably revisit. A proposal for substantial future work starts in `proposed/`; a decision already made starts in `implemented/`. Pick the class folder that matches the decision (see [Classification](#classification)).

+A feature-addition note may be consolidated into the later removal note only when the feature is absent from production code, configuration, schemas, durable or wire formats, migration, and compatibility behavior; no current documentation presents it as available; and no test exercises it as supported behavior. Removal rationale and tests that verify absence may remain. The removal owner preserves the original motivation, why it no longer justified the feature, alternatives to full removal, the capability given up, conditions for reintroduction, and verification of complete absence. Obsolete implementation inventories and tests that only verified the deleted behavior are not current verification contracts. Removing one transport, default, implementation, or presentation is partial supersession, as is any surviving durable data or compatibility handling.

+# Agent Notes
+
+[English](README.md) | 中文
+
+这里存放一类设计文档。**Agent Note（agent 决策记录）** 记录塑造本代码库的决策或提案：代码和文档无法承载的*为什么*以及*放弃了什么*。本文件是入口和契约：Agent Note 存放在哪里、何时需要写一份，以及[文件内格式](#the-file-format)。
+
+## 布局与命名
+
+每份 Agent Note 有两个维度，都编码在其**路径**中：`{lifecycle}/{class}/yyyy-mm-dd-topic-title.md`。
+
+- **生命周期**（顶层文件夹）是 Agent Note 的状态，Agent Note 随状态变化在文件夹之间移动：
+ - **`proposed/`**：实施前评审的提案；尚未构建（或仅部分构建）。
+ - **`implemented/`**：决策已交付。文件记录做了什么决定、否决了什么，并**与实际交付的内容保持同步**：当代码后续移动文件、重命名包（package）或更改键名/默认值时，Agent Note 在同一个变更中同步更新（仅限事实——路径、名称、结构——而非决策本身）。见 [implemented/AGENTS.md](implemented/AGENTS.md)。
+ - **`rejected/`**：提案经过讨论后被否决。保留以备查阅，避免同一问题被反复争论。
+- **类别**（嵌套文件夹）是决策的*种类*——见下方[分类](#classification)。
+
+文件名中的日期是该主题**首次提出**的时间（以 git 历史为准）。Agent Note 之间的交叉引用使用相对 Markdown 链接（`[topic](../../implemented/architecture/2026-…-….md)`），从不使用纯文字或编号，这样既可机械检查，也能在文件夹间移动时保持有效。
+
+目录树就是清单：浏览其生命周期/类别文件夹，或搜索仓库即可。请勿添加集中式 `INDEX.md`；设计理由见[不设索引的 Agent Note](implemented/process/2026-07-19-remove-generated-agent-note-index.md)。
+
+
+
+## 分类
+
+每份 Agent Note 属于 `scripts/agent-note-tree.ts` 中封闭集合里的一个路径编码类别；分类门禁拒绝其他文件夹。新增类别需要同时更新规范集合与本节。见[分类 Agent Note](implemented/process/2026-06-20-agent-note-classification.md)。
+
+| 类别 | 覆盖范围 |
+|---|---|
+| `feature` | 面向用户或模型的新功能。 |
+| `bug-fix` | 修正缺陷或弥补事故复盘（postmortem）发现的缺口。 |
+| `simplification` | 在不增加功能的前提下移除代码、行为或对外表面积。 |
+| `architecture` | 关于**交付源码**的结构性决策：包之间的关系、运行时词汇。 |
+| `process` | 代码**周边**的工具、策略或工作流——门禁、包管理器、vendor 化——不涉及运行时行为。 |
+| `testing` | 测试基础设施与策略。 |
+
+`architecture` 与 `process` 的界线：**architecture** 关乎我们交付的源码；**process** 关乎围绕源码的工具与工作流。（`refactor` 被有意排除：它与 `simplification` 重叠，而后者的判别标准「可观察行为是否改变」已经覆盖了它。）
+
+## 何时需要写一份
+
+每个非平凡变更都必须在同一 PR（Pull Request）中新增或更新至少一份 Agent Note。如果变更修改了行为、架构、跨文件或跨包契约、流程或工具、测试策略、磁盘、协议或配置格式，或者其他维护者可能合理重新审视的决策，就属于非平凡变更。对未来重大工作的提案从 `proposed/` 开始；已经做出的决策从 `implemented/` 开始。选择与决策匹配的类别文件夹（见[分类](#classification)）。
+
+更新已经拥有该决策的 Agent Note 即可满足规则；不要创建重复记录。只有不涉及行为、契约、结构、流程或理由变化的纯机械性或局部编辑才可豁免。Agent Note 永远不会被编辑为一个*不同的决策*：用新 Agent Note 取代旧记录，并让两个记录保持互相链接，除非后续依据下方规则完全合并旧记录。编辑 `implemented/` Agent Note 以跟踪其现有决策的所在位置是必需的，而非禁止的；见 [implemented/AGENTS.md](implemented/AGENTS.md)。
+
+被完全取代的 implemented Agent Note 可以合并到当前持有该决策的记录中，并删除原文件。删除前，当前记录必须保存所有独有的决策依据、备选方案、影响、验证契约和明确指出的覆盖缺口；修复所有入站链接；并在同一变更中删除中文对侧文件、一致性记录，以及[翻译配对 manifest（元数据清单）](../../scripts/translation-pairing.manifest.json)中对应的 `required` 条目。仅部分被取代的记录不符合此条件：保留两个记录并让它们互相链接，同时更新所有仍然适用的事实。合并不得将旧文件改写成与其相反的决策，也不得让 git 历史成为决策依据的唯一副本。
+
+只有当一项功能已从生产代码、配置、schema、持久化格式或协议格式、迁移和兼容行为中完全消失，当前文档不再将其描述为可用，且没有测试把它作为受支持行为来执行时，新增该功能的 Agent Note 才可合并进后续的移除记录。移除决策的依据和验证该功能已不存在的测试可以保留。移除决策的持有记录必须保留最初动机、为什么该动机已不足以证明保留该功能的合理性、完全移除之外的备选方案、放弃的能力、重新引入的条件，以及证明已彻底移除的验证。过时的实现清单和只验证已删除行为的测试不属于当前验证契约。仅移除一种传输、默认值、实现或展示属于部分取代；仍有任何持久数据或兼容处理也同样如此。
+
+
+
+## 文件格式
+
+每份 Agent Note 遵循统一的文件内格式，由 `pnpm run verify-agent-note-format`（[scripts/verify-agent-note-format.ts](../../scripts/verify-agent-note-format.ts)，`doc-sync`（文档同步门禁）的一环）强制执行；该格式的设计动机及其否决的替代方案见[统一格式 Agent Note](implemented/process/2026-07-05-uniform-agent-note-format.md)。
+
+### 头部块
+
+每份 Agent Note 的前三行严格为：
+
+```markdown
+# Agent Note:
+
+Status: <status>
+```
+
+后跟一个空行。`Status:` 的值有三种形式，且必须与文件所在的生命周期文件夹一致——门禁会交叉检查：
+
+- `Status: proposed`
+- `Status: implemented`
+- `Status: rejected — <why, in one line>`
+
+状态行不带日期、不带括号补充说明：文件名记录首次提出日期，git 记录其余一切；「以修订形式接受」之类的说明属于正文内容（在陈述决策的地方说明修订）。拒绝原因是唯一带内容的状态，因为读者查阅被否决的 Agent Note 时，结论正是他们要找的。
+
+### 正文骨架
+
+每份 Agent Note 的正文以 `## Problem` 开头：动机，写法上不依赖解决方案即可独立成文。后续内容取决于生命周期；固定章节使用以下规范名称且仅限这些名称，而真正独特的技术章节（包拓扑、协议契约、schema 等）在必需章节之间可自由组织。
+
+#### `proposed/`
+
+```markdown
+## Problem
+## Proposal
+…bespoke sections…
+## Alternatives considered
+## Acceptance criteria
+## Risks
+```
+
+`## Proposal` 描述拟议的变更，可以合理地使用将来时态——计划、迁移步骤和待解决问题在工作尚未完成时属于此处。`## Acceptance criteria` 说明什么可观察状态意味着完成。`## Risks` 涵盖可能出错的事项以及该变更有意放弃的东西。
+
+#### `implemented/`
+
+```markdown
+## Problem
+## Decision
+…bespoke sections…
+## Alternatives considered
+## Consequences
+```
+
+`## Decision` 以现在时态描述已交付的现实，整个文件按 [implemented/AGENTS.md](implemented/AGENTS.md) 的要求与之保持同步。`## Consequences` 记录权衡的代价**与**收益。提案阶段的标题在此属于规格用语，门禁会拒绝它们：`## Proposal`、`## Plan`、`## Migration plan` 和 `## Acceptance criteria` 不得出现在 implemented Agent Note 中（原因见 [slop 检查清单](../../docs/AGENTS.md)）。`## Testing`、`## Deferred` 或 `## Related` 章节在陈述现在时态的事实时是允许的。
+
+#### `rejected/`
+
+被否决的 Agent Note 是冻结的提案：保留提案时的所有章节（包括 `## Acceptance criteria` 或 `## Plan`），结论写在 `Status:` 行上。仅头部块、`## Problem` 开头、`## Proposal` 章节以及下方的「曾考虑的替代方案」强制要求适用。
+
+### 曾考虑的替代方案——必需
+
+每份 Agent Note 都必须包含 `## Alternatives considered` 章节：每个真实的替代方案及其落选原因，每个替代方案用一个加粗引导的段落，或对争议较大的替代方案用 `### Why not <X>?` 子节。记录决策时不记录它击败了什么，就是在邀请反复争论——正是这些 Agent Note 存在的意义所要防止的。
+
+替代方案是记录下来的，不是凭空编造的。日期早于 2026-07-05 且替代方案无法从记录中重建的 Agent Note，在该章节位置放置以下精确注释，门禁仅对格式规范之前的文件接受此注释：
+
+```markdown
+<!-- agent-note-format: alternatives-not-recorded (pre-format Agent Note) -->
+```
+
+### 在生命周期之间移动
+
+将文件在生命周期文件夹之间移动意味着在同一个变更中更新 `Status:` 行并满足目标文件夹的骨架要求——否则门禁会失败。具体而言，`proposed/` → `implemented/` 将 `## Proposal` 改写为现在时态的 `## Decision`，将 `## Acceptance criteria` 和 `## Risks` 折入 `## Consequences`（或折入一个现在时态的 `## Testing`/`## Verification` 章节，用于描述现在锁定该行为的内容），并用实际交付的内容替换计划——即 [implemented/AGENTS.md](implemented/AGENTS.md) 所要求的改写，使之机械化。`proposed/` → `rejected/` 仅在 `Status:` 行添加原因并冻结文件。
+
+### 中文对侧文件
+
+`.zh.md` 对侧文件按 [i18n 契约](../../docs/i18n/README.md)逐章节镜像其英文兄弟文件的结构；机器检查的头部标记（`# Agent Note: ` 和 `Status:` 行）保持英文原样不翻译。格式门禁跳过 `.zh.md` 文件——配对门禁负责它们的一致性。

+# Agent Note: 由 dsh-llm 拥有的提供方无关内容块词汇
+
+Status: implemented
+
+[English](2026-06-11-content-block-vocabulary.md) | 中文
+
+## 问题
+
+harness 需要一套统一的内部消息语言，供 agent loop（智能体循环）、会话日志和所有插件共同使用。
+
+## 决策
+
+自主拥有词汇：消息是类型化内容块的数组（`text`、`reasoning`、`tool-call`、`tool-result`），其联合类型派生自可合并扩展的 `ContentBlockMap`，插件通过声明合并添加新的块类型。同一可合并扩展映射模式为所有「字符串化」字段提供类型（`MessageSource`、`FinishReason`、`TurnTrigger`、`TurnEndReason`）。流式输出采用原始分片协议；`BlockAssembler` 是唯一的共享组装实现。适配器负责转换为提供方的协议格式（wire format）——映射成本留在适配器中，正是它该在的地方。
+
+会话内上下文注入（`context/message`）和轮次中途 steering（`steering/message`）最初渲染为带标签的 user-role 信封（system-reminder 模式），而非引入新角色，因此适配器无需承担额外负担。如今两者都投影为无包装的普通用户内容；见[注入内容信封 Agent Note](../simplification/2026-07-20-unwrap-injected-content-envelopes.md)。实际适配器验证已确认此渲染方式符合当前 DeepSeek 的行为；如果未来某提供方出现不兼容，应在该适配器内处理，而非引入新的规范角色。
+
+## 曾考虑的替代方案
+
+- **镜像 DeepSeek/OpenAI chat-completions 结构**：对第一个提供方零映射成本，但对富内容（推理、结构化块形式的工具结果）处理不便。
+- **原样采用 Anthropic Messages 块结构**：经过实战检验，但规范类型将镜像一个 harness 并非首要对接的第三方 API。
+
+## 后果
+
+- 推理（reasoning）在核心层有了归属，无需依赖提供方特有的结构。
+- 多模态块只有在适配器、UI 和上下文压缩（context compaction）三方协同支持后才会回归；见 [drop-image Agent Note](../simplification/2026-07-04-drop-image-content-block.md)。
+- 缓存提示与 assistant prefill 在有实际适配器能兑现之前保持缺席；见[无生产者的词汇变体](../simplification/2026-07-04-prune-producerless-vocabulary-variants.md)与[无端到端可用路径的请求旋钮](../simplification/2026-07-04-drop-inert-request-knobs.md) Agent Note。
+- 每个适配器都需承担翻译成本；首批真实适配器已验证了流式输出协议，新适配器应继续在适配器本地测试中验证其提供方特有的映射。
+- 跨包（package）边界的 ID 使用品牌类型（`CallId`、agent 与会话共享的 `SessionId`）——零运行时开销的名义类型。

-# Agent Note: Custom typed tool-schema DSL instead of schemastery
-
-Status: implemented
-
-## Problem
-
-Tool parameters must reach the model as standard JSON Schema while giving tool authors typed `execute(args)` without casts. Schemastery already serves plugin config, but the tool-author API needs per-property `required: true` booleans rather than JSON Schema's separate `required` array.
-
-## Decision
-
-This decision is superseded by the [unified JSON-value schema DSL](2026-07-20-unified-json-value-schema-dsl.md), which retains the small authoring surface while making parameters and typed values share one vocabulary. `ParameterSchemaSpec` keeps per-property `required: true`; `InferArgs<S>` maps required keys to non-optional properties; `parameterSchemaSpecToJsonSchema()` compiles the implicit open object root; and `defineTool()` ties inference, compilation, and validation together. Raw JSON-Schema `ToolDefinition`s remain accepted by `ToolRegistry.register()` for MCP and other external tools.
-
-## Alternatives considered
-
-**Schemastery** (already vendored, used for plugin Config) was evaluated and rejected for this use: it targets validation / transformation against StandardSchema, not JSON Schema *generation*, so it would add indirection without producing the wire format cleanly.
-
-## Consequences
-
-- First-party tool authors get zero-cast typed args; the type gymnastics cost stays inside the core package (sanctioned by the AGENTS.md type-safety policy).
-- The owning unified note defines the current nodes, literal constraints, unions, JSON-value boundary, and object-openness rules.
-- The `InferArgs` mapping is regression-tested at the type level after an early optionality bug.

## Problem
The session log needs two different protections: immutable ownership of each stored fact, and checks for relationships among facts across time and service seams. Conflating them in an optional development plugin would leave production history vulnerable; trying to express both through TypeScript readonly types would not create a runtime boundary or describe relational rules.

+# Agent Note: 源端拥有的会话不可变性与开发模式不变式
+
+Status: implemented
+
+[English](2026-06-11-dev-invariants-over-deep-readonly.md) | 中文
+
+## 问题
+
+会话日志需要两种不同的保护：对每条已存储事实的不可变所有权，以及对跨时间和服务 seam 的事实之间关系的检查。如果将二者混为一个可选的开发插件，生产环境的历史记录将失去保护；如果试图通过 TypeScript readonly 类型同时表达两者，既无法建立运行时边界，也无法描述关系规则。
+
+会话日志是回放、请求重建、持久化与用户可见历史的持久真源。会话包（package）外部的代码必须能检视历史，但不能保留一个可在之后改写历史的引用；从调用方接受的输入也不能继续连接到调用方拥有的可变对象。
+
+单个值的不可变性只是契约的一半。一份日志可以包含完全不可变的记录，但其序列、轮次/步骤嵌套、工具调用配对、作用域分发或重建的模型请求是错误的。这些规则涉及多条记录或多个服务，无法通过冻结单个对象来建立。
+
+TypeScript readonly 类型不是充分的运行时边界。它们在程序运行时消失，类型转换可以绕过它们，而递归的 `DeepReadonly<T>` 会扩散到每个日志和消息消费方，尽管某些下游请求处理 API 有意使用可变值。
+
+## 决策
+
+职责在始终启用的存储边界与可选的开发断言之间分离。
+
+### Session 拥有不可变历史
+
+`Session` 仅在一次递归遍历完成无损 JSON 快照的物化之后才接受事件。该遍历拒绝不支持的值，并产出进入日志的确切分离记录，因此验证与存储不会从有状态的 getter 观察到不同的值，也不会保留调用方拥有的嵌套引用。
+
+被接受的事件及其所有后代在发布前被深度冻结。`append()` 返回该拥有的冻结事件，`session/event` 观察者接收同一记录，`session.events` 返回冻结的数组快照。先前返回的数组不会因后续 append 而增长。种子记录在构造成功前经过相同的验证、快照与冻结边界。
+
+此保证属于 `Session` 而非可选监听器，因为每种组合都依赖可信的历史。无论是否注册了开发支持插件，生产部署、聚焦测试或自定义嵌入都获得相同的存储语义。
+
+### 派生请求保持分离
+
+`deriveMessages()` 将已记录的表面事件投影为分离的、深度冻结的 `Message` 对象，并返回一份新的数组快照。因此请求组装可以将派生历史与其他输入组合，而不会暴露一条回到日志的路径。缓存复用安全的不可变投影，而非为每次模型调用重新克隆完整历史。
+
+### 包拥有的不变式配套插件检查关系
+
+`dsh-invariants` 注册可配置的 `ctx.invariants` 服务，本身不包含产品检查。每个包发布一个 `./invariant` 所有权配套插件；`dsh-session`、`dsh-agent`、`dsh-scope` 和 `dsh-agent-loop` 目前添加需要 trace 状态或观察另一个 seam 的规则：单调递增的序列号、轮次与步骤嵌套、工具调用/结果配对、合法的 agent（智能体）状态转换、主体正确的作用域分发，以及循环构建的请求与从其会话日志前缀重建的请求之间的等价性。全局启用和包名 regex 过滤器归该服务所有（见[包拥有的不变式服务](2026-07-19-package-owned-invariant-service.md)）。
+
+当会话配套插件附加到已有或已播种的会话时，它回放不可变日志以重建跟踪状态。服务为每项贡献提供一个可 dispose（资源释放）的子 fiber，因此轮次中途热重载是安全的，同时不赋予诊断逻辑对会话存储的所有权。
+
+## 曾考虑的替代方案
+
+### 全面的 deep-readonly 类型
+
+[被否决的不可变公共表面提案](../../rejected/architecture/2026-06-11-immutable-public-surfaces.md)会在公共日志和消息表面上应用递归 readonly 类型。这能提供编辑器反馈，但无法提供运行时保证：TypeScript 类型在运行时被擦除，插件代码可以通过类型转换绕过。它还会将 readonly 类型推入有意进行修改的消费方。在 `Session` 边界处的运行时所有权保护所有调用方，无需这种类型传播。
+
+### 仅在开发模式冻结
+
+仅当不变式插件安装时才冻结历史，会使核心保证依赖于组合方式。代码可能通过开发测试，却在生产环境或省略了该插件的聚焦组合中破坏历史。因此存储不可变性始终启用，而开销更大的关系检查则保持为可选的开发支持。
+
+### 仅在派生消息时克隆
+
+分离 `deriveMessages()` 能保护最常见的请求路径，但 `session.events` 的其他读取者、append 返回值和会话事件观察者仍能修改持久历史。日志必须保护自身的边界；派生投影是额外的隔离边界，而非替代品。
+
+## 后果
+
+- 每个被接受的实时或种子会话事件在任何观察者接收之前，都已从调用方拥有的输入中分离并深度不可变。
+- `session.events` 暴露稳定的不可变快照，而非私有的增长数组。
+- 请求侧的修改无法通过派生消息触及已存储的历史。
+- 开发构建可以启用关系断言而不改变存储行为；dispose 或过滤一个配套插件不会削弱日志不可变性。
+- `dsh-invariants` 配置全局启用状态以及包允许/阻止 regex 列表；每项检查仍由其产品包拥有并测试。
+- 运行时边界对每个被接受的事件产生一次递归快照与冻结的开销；后续读取者和缓存投影复用已拥有的不可变记录。

+# Agent Note: 事件溯源的会话与派生消息历史
+
+Status: implemented
+
+[English](2026-06-11-event-sourced-sessions.md) | 中文
+
+## 问题
+
+MVP 要求严格的基于事件的追踪，以及完全可回放的会话（严格的基于事件的 trace、logging 系统，会话完全可回放）。
+
+## 决策
+
+`Session` 是一份仅追加的、类型化的 `SessionEvent` 日志，是唯一的真源。LLM（大语言模型）消息历史从日志*派生*（`deriveMessages()`）；原始流分片被记录以保证 token 级别的回放保真度，而组装后的 `assistant/message` 事件才是派生的权威依据。回放/fork = 用已有日志初始化一个新会话。
+
+追加操作是同步的（热路径从不阻塞于 I/O）；`session/event` 是同步通知；持久化插件在后台缓冲写入，并在每个轮次结束时触发的 `session/flush` 检查点处等待排空。
+
+顺序契约：agent loop（智能体循环）*先*追加到会话，再发出对应的 Cordis 事件；`agent/step-result` waterfall（瀑布式事件）在 `assistant/message` 追加之前运行，因此日志记录的是工具调度实际使用的消息。回归测试固定了这一顺序。
+
+## 曾考虑的替代方案
+
+**可变消息数组 + 事件仅作通知发出**：更简单，但状态与日志可能分歧；采用事件溯源后，日志本身即是状态，分歧在结构上不可能发生。
+
+## 后果
+
+- 回放、追踪与遥测在结构上得到保证，而非事后附加。
+- 持久化仍是插件关注点；内存存储随 dsh-session 一起提供。
+- 事件词汇可通过合并扩展（插件可添加如压缩（compaction）事件）；[会话持久化](2026-06-14-session-persistence.md)在日志变为持久后冻结了其形状。
+- 派生成本随日志长度增长，压缩（未来插件）是预期的缓解手段，而非日志变更。

+# Agent Note: 微内核——通过 Cordis 事件分类体系实现扩展，唯一具体循环
+
+Status: implemented
+
+[English](2026-06-11-microkernel-event-taxonomy.md) | 中文
+
+## 问题
+
+产品原则是「一切皆插件」：钩子、/goal、/loop、动态工作流、上下文压缩（context compaction）、沙箱、权限、UI、持久化、MCP、skill（技能）都必须能以插件形式编写，无需修改核心。
+
+## 决策
+
+纯 Cordis 事件分类体系。agent loop（智能体循环）的扩展 seam 是带类型的事件，具有明确的分发模式：
+
+- **waterfall（瀑布式事件）**（around-middleware）：插件可变换、否决、恢复或包装：`agent/prompt-submit`、`agent/request`、`agent/request-error`、`agent/step-result`、`agent/turn-continuation`、`tools/pre-execute`、`tools/execute`、`tools/post-execute`、`llm/stream`、`system-prompt/assemble`。
+- **serial**（按监听器顺序依次 await；bail 值会阻止后续监听器执行）：用于有序检查点。所有 `agent/pre-step` 和 `agent/post-step` 监听器在全部弃权时才继续运行，而 `agent/turn-stop` 返回的第一个 stop 值即为最终的终止决策。
+- **parallel**（await 扇出）：每个监听器都必须获得独立执行的机会：`session/flush` 持久性检查点。
+- **emit**（同步 fire-and-forget）：用于通知：轮次/步骤边界、流分片、生命周期、错误，以及包含不可变 `tools/result` 观测的事件。
+
+事件词汇定义在接口包中（dsh-agent 声明 agent/* 事件）；`@deepseek-ai/dsh-agent-loop` 是唯一的具体循环插件，且自身可替换——外部不得依赖它。
+
+## 曾考虑的替代方案
+
+**专用中间件栈（koa-compose 风格）** 与**显式阶段状态机（插件向其中插入阶段）**：两者都需要重新实现 Cordis 原生事件系统已提供的分发、dispose（资源释放）与重载语义；作为 Cordis effect，监听器天然获得 HMR（热模块替换）与 dispose 能力。
+
+## 后果
+
+- 每个 MVP 功能都映射到一个监听器（[功能→机制映射](../../../../docs/cookbook/extension-cookbook.md#the-feature--mechanism-map)是证明义务，保持更新）。
+- HMR 与 dispose 无需额外工作：监听器和注册均为 Cordis effect。
+- waterfall 语义（调用 `next()` 或短路）不直观，需要教学——在 AGENTS.md 中记录，并由组合测试覆盖。
+- 循环必须具备防御性：插件异常在轮次级别被隔离，任何 seam 发出的 steering（中途引导）永远不会被搁置（有回归测试保障）。

## Problem
`defineTool` ([the unified schema DSL](2026-07-20-unified-json-value-schema-dsl.md)) gives tool authors a typed `execute(args)` via the `InferArgs<S>` mapping. But that type is a compile-time claim about a value that arrives at runtime as model-generated JSON: nothing forced the model to honor the schema, so a malformed call — missing a required key, a string where a number was declared, or a literal outside the declared set — reached `execute` typed-in-name-only. The tool body then either crashed on the bad shape or silently misbehaved.

+# Agent Note: 模型边界处的运行时参数校验
+
+Status: implemented
+
+[English](2026-06-11-runtime-arg-validation.md) | 中文
+
+## 问题
+
+`defineTool`（[统一 schema DSL](2026-07-20-unified-json-value-schema-dsl.md)）为工具作者的 `execute(args)` 提供了经 `InferArgs<S>` 映射的类型化参数。但该类型只是对运行时值的编译期声明，而这个值实际上是模型生成的 JSON：没有任何机制强制模型遵守 schema，因此畸形调用（缺少必需键、声明为数字的位置传入字符串，或字面量超出声明的集合）会以「仅名义类型化」的状态到达 `execute`。工具函数体随后要么在错误形状上崩溃，要么静默地行为异常。
+
+## 决策
+
+`validateArgs(spec, args): string[]` 编译 `ParameterSchemaSpec`，并委托共享的 `validateJsonSchemaValue()` 遍历器，对格式正确的声明返回可读的违规列表。`defineTool` 在定义时对编译后的参数 schema 创建快照，并在调用类型化函数体之前执行校验；存在违规时会抛出 `ToolArgsError`（`INVALID_ARGS`），注册表将其作为模型可据以修正的错误结果返回。
+
+校验器与编译器因此共享完全一致的语义：隐式参数根是开放对象；必需键仅来自 `required: true`；默认值仍是注解；显式嵌套对象遵循其声明的开放性；数组通过 `items` 递归；标量字面量约束保证类型正确；`oneOf` 仅在恰好一个分支匹配时才接受。原始注册的工具自行负责输入校验。
+
+## 后果
+
+- 模型在自身畸形调用上获得可操作的反馈，而非不透明的崩溃，弥合了 `InferArgs` 的承诺与运行时现实之间的鸿沟。
+- 校验器与 `InferArgs` 必须保持一致；一项[属性测试](../testing/2026-06-11-property-based-testing.md)生成满足 spec 的参数并断言它们通过 `validateArgs`（同时断言定向破坏的参数被拒绝），以机械方式封堵漂移风险。
+- `ToolArgsError` 目前是带 `code` 字段的普通 `Error`；如果日后引入 harness 级别的错误分类体系，它将变为子类，但不影响读取 `.message` 的调用方。
+- 校验开销相对于一次模型调用可忽略不计。

## Problem
Failures crossed seams as bare strings. A tool error flattened to a text block — name, code, and stack lost — so a future sandbox/retry plugin couldn't tell ENOENT from EACCES, and the model got less actionable feedback than it could. A non-Error throw degraded further: the loop wrapped it in `new Error(String(x))`, dropping any code. And `LlmError` was the only typed error in the system, with no shared base, so there was nothing for a consumer to `instanceof` against generically.

+# Agent Note: 结构化错误分类体系
+
+Status: implemented
+
+[English](2026-06-11-structured-error-taxonomy.md) | 中文
+
+## 问题
+
+故障跨越 seam 时只是裸字符串。工具错误被扁平化为一个文本块（name、code 和 stack 全部丢失），导致未来的沙箱/重试插件无法区分 ENOENT 和 EACCES，模型得到的反馈也不如本可以那样具有可操作性。非 Error 的 throw 退化更严重：agent loop（智能体循环）将其包装为 `new Error(String(x))`，丢弃了所有 code。而 `LlmError` 是系统中唯一的类型化错误，没有共享基类，消费方无法对其进行通用的 `instanceof` 判断。
+
+## 决策
+
+在 `dsh-llm`（叶子包，所有其他包都已依赖它，不引入新的依赖边）中引入一个 `HarnessError extends Error` 基类：稳定的 `code`（与 `message` 分离）、通过 `ErrorOptions` 进行 `cause` 链接、`name` 默认为子类名。`isHarnessError` 在 seam 处做类型收窄。
+
+- `LlmError` 和 `ToolArgsError`（dsh-tools）继承该基类，保留各自既有的 code。
+- `ToolExecutionResult` 新增可选字段 `error: { name, code }`，在注册表的 catch 中当抛出值为 `HarnessError` 时填充。agent loop 将其转发到 `tool/result` 会话事件（该事件也新增了同一可选字段），使结构化的失败信息存活到日志中，供重试/沙箱插件和回放使用。面向模型的文本块保持不变。
+- agent loop 的 `toError` 将非 Error 的 throw 包装为 `HarnessError`（`code: 'UNKNOWN'`，原始值作为 `cause` 链接），而非裸 `Error`；这样即使是不规范的 throw 也能携带可路由的 code 进入会话的 `error` 事件（该事件此前已暴露 `code`）。
+
+## 后果
+
+- 错误端到端可机器路由：插件可以基于 `error.code` 分支，而无需对消息做子串匹配。
+- 一个基类被广泛导入，但它位于所有包已经依赖的包中，代价仅是一条 import 语句，而非新的依赖边。
+- `deriveMessages` 不会将 `error` 暴露到模型历史中——模型仍然看到文本块；结构化字段服务于代码和回放。
+- 参数校验保留其既有的 code 和行为；包自有的诊断不变式独立携带稳定 code，使不变式注册表无需导入产品包。共享基类增加了跨 seam 的路由元数据，不改变面向模型的文本。

## Problem
On the wire, tool schemas travel in a dedicated `tools` field of the model request, not in prompt text. Architecturally, though, "what the model is told it can do" is one coherent concern: prompt sections and the tool list are assembled from the same plugin contributions and consumed at the same moment.

+# Agent Note: 工具 schema 是系统提示词组装的一部分
+
+Status: implemented
+
+[English](2026-06-11-tool-schemas-in-prompt-assembly.md) | 中文
+
+## 问题
+
+在协议格式（wire format）层面，工具 schema 通过模型请求中专用的 `tools` 字段传输，而非嵌入提示词文本。然而从架构角度看，「模型被告知它能做什么」是一个统一的关注点：提示词段落与工具列表由相同的插件贡献组装，并在同一时刻被消费。
+
+## 决策
+
+`PromptAssembly { sections, tools }`：系统提示词服务同时收集有序的文本段落和工具 schema（工具注册表自动贡献一个提供方）。agent loop（智能体循环）每个步骤消费一份 assembly；适配器将 `sections` 映射到提供方的 system 槽位，将 `tools` 映射到协议格式的 `tools` 字段。因此 `system-prompt/assemble` waterfall（瀑布式事件）是模型预先获知的所有信息的唯一拦截点：工具过滤（ToolSearch / 渐进式披露）是一次 assembly 重写，与提示词编辑无异。
+
+## 曾考虑的替代方案
+
+**循环从工具注册表和提示词服务分别查询**：将一个统一的关注点拆到两个 seam 上；任何想影响「模型被告知什么」的拦截（工具过滤、plan 模式）都需要在两个接口上各挂一个监听器，而非一次 assembly 重写即可完成。
+
+## 后果
+
+- 一条 waterfall 统管模型的常驻上下文；plan 模式等插件可以在一个监听器中同时替换提示词文本和可见工具。

## Problem
The harness has swappable capabilities — bash execution today, sandboxed/remote executors and alternative model providers tomorrow. A capability has three concerns that change at different rates and for different reasons: the *contract* (what the capability is), the *implementation* (how it runs), and the *consumer surface* (what the model and other plugins program against). Bundling them in one package couples those rates of change — swapping a local executor for a sandboxed one would churn the tool schemas the model sees, even though the model-facing contract never changed.

+# Agent Note: 能力 seam——接口／实现／消费方三分
+
+Status: implemented
+
+[English](2026-06-13-capability-seams.md) | 中文
+
+## 问题
+
+harness 具有可替换的能力：当前是 bash 执行，未来会有沙箱化／远程执行器和替代模型提供方。一项能力涉及三个关注点，它们以不同速率、因不同原因变化：*契约*（这项能力是什么）、*实现*（它如何运行）、*消费方接口*（模型和其他插件面向什么编程）。将三者捆绑在一个包（package）中会耦合这些变化速率——把本地执行器换成沙箱化执行器时，模型看到的工具 schema 也会被搅动，尽管面向模型的契约从未改变。
+
+这与「谁在运行时提供、谁需要一项能力」是不同的问题，后者 Cordis 已通过服务 + `inject` 解决（提供方注册 `ctx.bash`；消费方声明 `inject: ['bash']`，其 fiber 挂起直到服务存在）。该机制是必要的，但不决定包的边界；本 Agent Note 决定的是包的边界。
+
+## 决策
+
+一项可替换的能力由**三个包**构成：
+
+1. **接口**——一个抽象服务加词汇类型，拥有 `ctx.<key>`，仅依赖其词汇依赖（例如 `dsh-bash`：`BashExecutor`、`BashRunResult`、`BashProcess`）。
+2. **实现**——一个具体子类，以插件形式加载（例如 `dsh-bash-local`：子进程、进程组 kill、溢出文件截断）。沙箱化／远程后端是实现同一接口的兄弟包。
+3. **消费方**——模型和插件看到的内容（例如 `dsh-tool-bash`：`bash` schema，后台句柄注册到通用任务运行时）。消费方 `inject` 接口键，从不导入实现类型。
+
+实现与消费方由此独立演进：沙箱化执行器替换 `dsh-bash-local` 时无需触碰任何工具 schema。
+
+当各部分确实属于同一个关注点时，三分并非强制：LLM（大语言模型） seam 将接口 + 消费方合并为 `dsh-llm`（消费方是 agent loop（智能体循环）本身，而非可替换的 schema 表面），适配器作为实现包。不要预防性地拆分——如果一项能力只有一种可设想的实现和一个消费方，就保持为一个包，直到第二种出现。
+
+## 曾考虑的替代方案
+
+- **单一合并包**：否决。因为它重新耦合了三分设计本要分离的三种变化速率（这正是拆分的意义所在）。
+- **`@cordisjs/plugin-capability`**：这是完全不同的维度。它是一个权限／能力*安全*服务（具名权限加继承，通过 `ctx.capability.test` 对会话进行检测），是延后的权限/沙箱工作（`tools/pre-execute` deny/ask seam）的候选方案，不是替换实现的机制。混淆这两个「能力」概念正是本 Agent Note 所指出的陷阱。
+
+## 后果
+
+每项能力需要更多包和更多样板代码（一组 `package.json`/`tsconfig`/README，加上 inject 接线）。换来的是：实现与消费方独立发布和版本管理，新后端永远不会波及面向模型的契约。该规则记录在 [AGENTS.md](../../../../AGENTS.md) § Conventions（「Capability seams are three packages」）和 [architecture.md](../../../../docs/architecture.md) §「Capability seams」中；bash 三件套是参考模板。何时合并、何时拆分是一个判断问题，架构文档对此有详细说明——本 Agent Note 记录的是*为什么*默认选择拆分。

## Problem
`dsh-llm` owns a provider-neutral streaming vocabulary — the `StreamChunk` protocol (`block-start`, `text-delta`, `reasoning-delta`, `tool-call-delta`, `block-end`, `usage`, `finish`) and the content-block types ([the content-block vocabulary](2026-06-11-content-block-vocabulary.md)). A vocabulary defined against a single adapter risks baking that adapter's quirks into the "neutral" contract: anything the one implementation happens to do becomes the de-facto spec, and the abstraction is unverified until a second provider arrives — by which point the leak is expensive to fix.

+# Agent Note: 以两个 LLM 适配器作为设计验证孪生体
+
+Status: implemented
+
+[English](2026-06-13-twin-llm-adapters.md) | 中文
+
+## 问题
+
+`dsh-llm` 拥有一套提供方无关的流式词汇：`StreamChunk` 协议（`block-start`、`text-delta`、`reasoning-delta`、`tool-call-delta`、`block-end`、`usage`、`finish`）以及内容块类型（[内容块词汇](2026-06-11-content-block-vocabulary.md)）。如果词汇仅针对单个适配器定义，就有可能将该适配器的特异行为烘焙进「中立」契约：唯一实现碰巧做了什么，什么就成为事实上的规范；在第二个提供方到来之前，抽象层未经验证——而届时泄漏已代价高昂。
+
+## 决策
+
+从一开始就针对同一份契约交付**两个**适配器，刻意基于不同的内部实现构建：
+
+- `dsh-llm-deepseek`：手写 `fetch` + SSE（Server-Sent Events）解析，直接对接 DeepSeek API。
+- `dsh-llm-pi-ai`：通过 `@earendil-works/pi-ai` 库访问同一端点（该库有自己的事件词汇）。
+
+二者共同执行的规则是：**凡 StreamChunk 词汇无法为两个实现同时表达的内容，都是核心词汇的缺陷**——立即暴露，而非等到下一个提供方接入时才发现。这对孪生体确定了现已记录在 `dsh-llm/src/types.ts` 中 `StreamChunk` 上的约定：usage 在 finish 之前发出、finish 之后不再有任何事件、工具调用的 `arguments` 全程以原始 JSON 字符串传递，以及消费方必须在两侧都处理的两条合法错误路径（`stream()` 抛异常，*或者*以 `finish {kind:'error'|'aborted'}` 结束）。后一项分歧正是由基于库的适配器暴露出来的，单一手写适配器会将其隐藏。
+
+## 曾考虑的替代方案
+
+- **单一适配器**：代码更少、e2e 成本减半，但「提供方无关」的声明无从验证；词汇会默默编码 DeepSeek-via-fetch 的假设。
+- **mock 第二适配器**：更便宜，但不会触及真实提供方的协议格式（wire format）怪癖，因此证明力有限。孪生体是真实对真实的验证。
+
+## 后果
+
+孪生体使适配器和需要密钥的 e2e 维护量翻倍——两者都覆盖 V4 Flash 和 Pro 在各代表性推理（reasoning）模式下的行为——换来的是持续的 seam 中立性验证和第二份实现示例。两个适配器均使用 `apiKey`、`baseURL` 和 `models`；手写适配器暴露 `thinking`/`reasoningEffort`，pi-ai 适配器暴露一个 `reasoning` 级别。未来如果有一致性测试套件，可以通过后续 Agent Note 论证退役其中一个适配器。

## Problem
-Sessions lived only in memory. The example `session-jsonl.ts` plugin (duplicated byte-for-byte in both examples) was write-only telemetry: it buffered `session/event` and appended JSON lines, with no read/replay path, no crash-safety (no fsync, no atomic write, a fire-and-forget dispose drain), no listing, and no format versioning. Nothing could rehydrate a past session from disk into a live agent, so durable resume ("continue yesterday's task"), durable forking, and the ACP `session/load` method ([ACP support](../feature/2026-06-14-acp-agent-client-protocol.md)) were all impossible.
+Sessions lived only in memory.

Nothing could rehydrate a past session from disk into a live agent, so durable resume, durable forking, and host-side session browsing were all impossible.
The [event-sourced model](2026-06-11-event-sourced-sessions.md) makes the append-only log the single source of truth and derives LLM history from it. Persistence had to stay faithful to that: persist the existing `SessionEvent` directly, with no parallel "persisted message" type that the log is converted to and from. The backend also had to be swappable — a file store now, a database store later — behind one interface.
@@ -19,16 +21,16 @@ Key choices recorded here because they are durable, contested, and surprising:
- **The canonical durable log persists every `SessionEvent` verbatim, including `assistant/chunk`.** `deriveMessages()` skips chunks, and a chunk-filtered rollout (Codex's `policy.rs`) is tempting — but `seq = log.length` and the load-validation `events[i].seq === i` require a *contiguous* log; filtering chunks out would leave holes and break both the contract and resume. A chunk-filtered projection is possible later as a derived view with its own renumbering, but it is NOT the canonical log.
- **Append-only; a crashed turn is closed, never truncated.** Flushed events are never rewritten. The [semantic checkpoint policy](../bug-fix/2026-07-21-semantic-session-checkpoints.md) drains the request before model dispatch, a recorded top-level call before tool dispatch, and the complete response/result batch after a step; the loop drains the final turn boundary. Because one interrupted turn may contain substantial valid work, `load` preserves its contiguous, parseable events and appends risk-classified error results for unanswered assistant calls, a missing `step/end`, and `turn/end` with `{ kind: 'interrupted' }`. The synthetic results keep resumed provider transcripts valid. Only an incomplete final record is discarded; a parse error or sequence gap at or before the last real `turn/end` is corruption and makes the session unloadable.
-- **File backend canonical, DB backend a proven drop-in.** `SessionEvent` maps 1:1 onto a row `(session_id, seq, type, time, data)` — `append` is INSERT (in a transaction asserting the contiguous-seq contract), `load` is SELECT … ORDER BY seq. `dsh-session-persistence-sqlite` is exactly this: a `SessionPersistence` subclass with no interface change (opencode runs this exact shape on SQLite/WAL), and it passes the same `runPersistenceContract` suite as the JSONL backend — so the contract holds both backends to identical semantics (lazy materialization, interrupted-turn close on load, contiguous-seq), expressed once over file bytes and once over rows.
-- **Metadata is out-of-log.** Format version, cwd, and lineage are storage concerns, not replayable conversation state, so they live in a `SessionHeader` owned by `dsh-session` and attached to a `Session` via a new readonly `session.header` — never in `SessionEventMap`, never reaching `deriveMessages()`. The alternative (a merge-extensible `session/meta` event as log line 0) was rejected: an in-log event would ride along with a seeded/forked session for free, but metadata is not replayable state, so the explicit out-of-log header seam is the cleaner cost. (The header was originally split into an immutable `SessionHeader` plus a mutable `SessionSummary` whose union was `SessionMeta`; the mutable summary was later removed as dead state — see [Drop the mutable session summary](../simplification/2026-06-19-drop-mutable-session-summary.md).)

Its database carries a dedicated application id and monotonic schema version. A pristine file creates all tables and stamps both header values in one transaction; an unversioned file with any user-defined schema object or application identity, a foreign current-version identity, and every non-current version reject before journal-mode mutation.

- **`ctx.agents.create()` and `ctx.agents.resume()` are async factories; resume additionally crosses the persistence boundary.** `ctx.agents.resume({ resumeSessionId })` awaits `ctx.sessionPersistence.load`, recreates the live session with the loaded events (so `lastTurnNumber`/`deriveMessages` continue), and registers the fresh agent under the exact resumed id. The agent-loop does NOT hard-inject `sessionPersistence` (that would pend non-persistent demos forever); `resume` rejects with a clear error when it is absent.
## Alternatives considered
-Each key choice above records its rejected alternative where the choice is stated: a **chunk-filtered canonical log** (Codex's `policy.rs` shape) — breaks the contiguous-seq contract; **truncating a crashed turn** — silently destroys a long autonomous run's real work; an **in-log `session/meta` event as line 0** — metadata is not replayable state; **hard-injecting `sessionPersistence` into the loop** — would pend non-persistent demos forever.

Format versioning: the header carries a `version`; `load` rejects any non-current version (no migration — the pre-release session format is pinned at `SESSION_FORMAT_VERSION = 0` and absorbs shape churn, per the AGENTS.md pre-release stance). Stated honestly: append-only + flush is robust to partial trailing writes (tolerated on load) but not to fsync-less power loss mid-line; a DB/WAL backend is the stronger option later.
## Consequences
-Two new packages and the metadata seam in `dsh-session` (`session.header`, the `create(id?, options?)` signature). Bought: durable resume/fork, a read/replay path, crash tolerance, and the foundation the ACP `session/load` ([ACP support](../feature/2026-06-14-acp-agent-client-protocol.md)) needs — all over the existing event-sourced log, with the backend swappable behind one interface. The reusable `runPersistenceContract` suite holds every backend to the same append-only, contiguous-seq, lazy-materialization, and serializability semantics. Persisting the full log also settles event fidelity: `assistant/chunk` remains verbatim.

+# Agent Note: 会话持久化作为基于现有 `SessionEvent` 的抽象服务
+
+Status: implemented
+
+[English](2026-06-14-session-persistence.md) | 中文
+
+## 问题
+
+会话此前仅存在于内存中。示例插件 `session-jsonl.ts`（在两个示例中逐字节重复）是只写的遥测：它缓冲 `session/event` 并追加 JSON 行，没有读取/回放路径，没有崩溃安全性（无 fsync、无原子写入、fire-and-forget 的 dispose 排空），没有列表功能，也没有格式版本控制。没有任何机制能将磁盘上的历史会话重新注入到活跃的 agent（智能体）中，因此持久恢复、持久 fork 以及宿主侧的会话浏览都无法实现。
+
+[事件溯源模型](2026-06-11-event-sourced-sessions.md)将仅追加日志作为唯一真源，并从中派生 LLM（大语言模型）历史。持久化必须忠实于这一设计：直接持久化现有的 `SessionEvent`，不引入需要来回转换的并行「持久化消息」类型。后端也必须可替换——当前用文件存储，以后用数据库存储——统一在一个接口之后。
+
+## 决策
+
+持久化是一个抽象的**能力 seam**（[能力 seam](2026-06-13-capability-seams.md)，`dsh-bash` 模板），而非循环或核心逻辑：
+
+1. **接口**（`dsh-session-persistence`，`ctx.sessionPersistence`）：一个抽象的 `SessionPersistence` 服务，提供 `create`/`append`/`load`/`list`。其持久化单元就是现有的 `SessionEvent`（`{ type, seq, time, data }`），原样复用，无转换类型。
+2. **实现**（`dsh-session-persistence-jsonl`）：每个会话一个仅追加的逻辑 JSONL 日志（一行 `SessionHeader`，之后每行一个 `SessionEvent`，逐字节保留，**包括 `assistant/chunk`**），默认编码为[带校验和的 Zstandard 帧](2026-07-19-zstandard-jsonl-session-logs.md)，也可通过配置使用原始行。
+
+以下关键选择记录于此，因为它们是持久性的、有争议的、且出人意料的：
+
+- **规范的持久日志逐字节保留每个 `SessionEvent`，包括 `assistant/chunk`。** `deriveMessages()` 跳过分片，而过滤分片的方案（Codex 的 `policy.rs`）很有吸引力，但 `seq = log.length` 以及加载验证 `events[i].seq === i` 要求日志是*连续*的；过滤掉分片会留下空洞，同时破坏契约和恢复功能。基于分片过滤的投影可以作为派生视图在后续实现（带有自己的重新编号），但它不是规范日志。
+- **仅追加；崩溃的轮次被关闭，而非截断。** 已刷写的事件永不被重写。[语义检查点策略](../bug-fix/2026-07-21-semantic-session-checkpoints.md)会在模型分发前排空请求、在工具分发前排空已记录的顶层调用，并在步骤结束后排空完整的响应/结果批次；循环则排空最终轮次边界。由于一个被中断的轮次可能包含大量有效工作，`load` 保留其连续、可解析的事件，并为未应答的 assistant 调用追加按风险分类的错误结果、补一个缺失的 `step/end`，以及带 `{ kind: 'interrupted' }` 的 `turn/end`。合成的结果保证恢复后的提供方 transcript（文本记录）仍然有效。只有不完整的最后一条记录会被丢弃；在最后一个真实 `turn/end` 处或之前出现解析错误或序号间隙，属于数据损坏，会使该会话不可加载。
+- **文件后端为规范实现，数据库后端为经过验证的直接替换。** `SessionEvent` 1:1 映射到一行 `(session_id, seq, type, time, data)`：`append` 是 INSERT（在一个断言连续 seq 契约的事务中），`load` 是 SELECT … ORDER BY seq。`dsh-session-persistence-sqlite` 正是如此：一个 `SessionPersistence` 子类，接口无变化（opencode 在 SQLite/WAL 上运行的正是这个形状），且通过与 JSONL 后端相同的 `runPersistenceContract` 测试套件。该契约以相同的语义约束两个后端（惰性物化、加载时关闭中断轮次、连续 seq），一次表达在文件字节上，一次表达在数据库行上。其数据库拥有专用的 application id 与单调递增的 schema 版本。系统会在一个事务中为全新文件创建所有表并写入这两个 header 值；未版本化文件若带有任何用户定义的 schema 对象或应用标识、当前版本文件若带有外部应用标识，以及任何非当前版本文件，都会在修改日志模式之前被拒绝。
+- **元数据在日志之外。** 格式版本、cwd 和谱系是存储关注点，不是可回放的对话状态，因此它们存放在 `dsh-session` 拥有的 `SessionHeader` 中，并通过新的只读属性 `session.header` 附加到 `Session` 上——永远不进入 `SessionEventMap`，永远不到达 `deriveMessages()`。`createdAt` 是以 Unix epoch 毫秒表示的非负安全整数：运行时创建和持久化注册会拒绝小数值，JSONL 会验证解码后的 header，SQLite 则将其存入严格的 `INTEGER` 列。替代方案（一个可合并扩展的 `session/meta` 事件作为日志第 0 行）被否决：日志内事件会随 seed/fork 的会话免费携带，但元数据不是可回放状态，因此显式的日志外 header seam 是更干净的代价。（header 最初被拆分为不可变的 `SessionHeader` 加可变的 `SessionSummary`，二者的联合类型为 `SessionMeta`；可变 summary 后来因属于死状态而被移除——见 [移除可变会话摘要](../simplification/2026-06-19-drop-mutable-session-summary.md)。）
+- **`ctx.agents.create()` 和 `ctx.agents.resume()` 是异步工厂；恢复还跨越持久化边界。** `ctx.agents.resume({ resumeSessionId })` 等待 `ctx.sessionPersistence.load`，用加载的事件重建活跃会话（使 `lastTurnNumber`/`deriveMessages` 得以延续），并以原样恢复的 id 注册新 agent。agent loop（智能体循环）不会硬注入 `sessionPersistence`（那样会让非持久化的演示永远挂起）；当它不存在时，`resume` 会以明确的错误拒绝。
+
+## 曾考虑的替代方案
+
+上述每个关键选择都在陈述处记录了被否决的替代方案：**过滤分片的规范日志**（Codex 的 `policy.rs` 形式）破坏连续 seq 契约；**截断崩溃的轮次**会静默销毁长时间自主运行中的真实工作；**日志内 `session/meta` 事件作为第 0 行**——元数据不是可回放状态；**有限的非整数 `createdAt` 值**没有生产方，且与整数 Unix 毫秒存储及查询列不一致；**接受非全新的未版本化 SQLite 文件**可能覆盖无关对象或应用标识；**将 `sessionPersistence` 硬注入循环**会让非持久化的演示永远挂起。
+
+格式版本控制：header 携带一个 `version`；`load` 拒绝任何非当前版本（不做迁移——预发布阶段的会话格式固定为 `SESSION_FORMAT_VERSION = 0` 并吸收形状变动，遵循 AGENTS.md 的预发布立场）。坦率地说：仅追加 + 刷写对部分尾部写入是健壮的（加载时容忍），但对行写入中途的无 fsync 断电不健壮；数据库/WAL 后端是后续更强的选项。
+
+## 后果
+
+新增两个包（package），以及 `dsh-session` 中的元数据 seam（`session.header`，`create(id?, options?)` 签名）。收益：持久恢复/fork、读取/回放路径、崩溃容忍，以及基于现有事件溯源日志的宿主侧会话访问，后端在一个接口之后可替换。可复用的 `runPersistenceContract` 测试套件以相同的仅追加、连续 seq、惰性物化、整数元数据与可序列化语义约束每个后端。持久化完整日志还确定了事件保真度：`assistant/chunk` 保持逐字节不变。SQLite 初始化要么提交完整的自有 schema 与 header 标识，要么不留下任何会使下次打开受阻的部分 schema。

## Problem
A durable session-persistence backend (added in a companion change) uses the **turn** as its crash-recovery boundary: a crash can leave an unclosed final turn, which `load` closes with a synthetic `turn/end {kind:'interrupted'}` while preserving the turn's real events (see [session persistence](2026-06-14-session-persistence.md)). This recovery is only well-defined if nothing *legitimately* durable sits OUTSIDE a turn — between the last `turn/end` and the next `turn/start` — since such an event would be swept into the next turn's interrupted close.

+# Agent Note: 每个会话事件都封闭在一个轮次内
+
+Status: implemented
+
+[English](2026-06-15-turn-enclosure-invariant.md) | 中文
+
+## 问题
+
+持久化的会话持久化后端（在配套变更中引入）以**轮次**作为崩溃恢复边界：崩溃可能留下一个未关闭的最终轮次，`load` 会用一个合成的 `turn/end {kind:'interrupted'}` 将其关闭，同时保留该轮次的真实事件（见[会话持久化](2026-06-14-session-persistence.md)）。这种恢复只有在没有任何*合法的*持久事件位于轮次之外（即上一个 `turn/end` 与下一个 `turn/start` 之间的间隙）时才是良定义的，否则这类事件会被卷入下一个轮次的中断关闭中。
+
+这一假设并不成立。有两条路径在任何轮次之外记录了事件：
+
+1. **排队的用户消息。** agent loop（智能体循环）排空排队消息并在 `turn/start` *之前*追加 `user/message`——于是一个轮次自身的提示词落在了前一个 `turn/end` 与下一个 `turn/start` 之间的间隙中。
+2. **空闲时的上下文注入。** `agent.inject()` 直接追加一条 `context/message`。它在生产环境中的真实调用方是 `dsh-tool-bash`，后者从 `ctx.bash.onTaskDone` 注入后台任务完成通知——该回调在后台 bash 任务完成时触发，而这经常发生在 agent **空闲**（轮次之间）时。
+
+在情况 2 中，如果注入的 `context/message` 是 flush/dispose 之前的最后一个事件（之后没有轮次追加 `turn/end`），`scanLog` 会将其视为崩溃残留并在**恢复时丢弃**——注入的上下文已持久写入磁盘，但重新加载后被静默丢失。情况 1 本身无害（`user/message` 之后总会跟着它触发的轮次），但使「什么可以出现在轮次之外」这条规则变得模糊。
+
+## 决策
+
+**每个会话事件都位于一个轮次内部**：在 `turn/start` 与其匹配的 `turn/end` 之间。具体而言：
+
+- agent loop 在 `turn/start` **之后**（轮次内部）追加排队的 `user/message` 事件，而非之前。因此，一旦这些消息被记录，就欠下一个 `turn/end`，既有的 finalizer 保证它被写入。
+- agent **运行中**调用 `agent.inject()` 时，它会加入已打开的轮次。当前步骤执行 assistant 工具调用期间，已接受的上下文按到达顺序等待该批次结算，随后在每个已记录结果之后追加；即使执行中断，也会在轮次关闭前写入。
+- agent **空闲时**调用 `agent.inject()`，则将 `context/message` 包裹在一个一次性轮次中：`turn/start{trigger:{kind:'injection'}}` → `context/message` → `turn/end{completed}`。一个新的 `injection` 变体加入可合并扩展的 `TurnTriggerMap`。
+- agent loop 每次迭代从日志推导下一个轮次编号（`lastTurnNumber(session) + 1`），而不是维护一个私有计数器，这样空闲注入的一次性轮次不会与下一个真实轮次的编号冲突。
+- `dsh-session/invariant` companion 将该检查注册到 `ctx.invariants`：选中后，在没有打开轮次的情况下追加 `user/message` / `context/message` / `steering/message` 会抛出归因于 `@deepseek-ai/dsh-session` 的 `InvariantError`。
+
+可序列化性不变式在同一源码边界处强制执行（`Session.append` 对不可 JSON 序列化的数据抛出异常），因此「什么可以进入日志」现在由一个位置统一管控，而非由下游碰巧在监听的某个后端各自发现。
+
+## 曾考虑的替代方案
+
+**放宽读取端而非约束生产端**——让 `scanLog` 提交位于已打开轮次之外的事件。否决：一条单一、可检查的生产端规则优于一个更宽松的边界扫描（后者需要同时推理部分轮次*和*轮次间的散落事件）。
+
+## 后果
+
+轮次现在是*唯一的*持久性/回放边界，因此[会话持久化](2026-06-14-session-persistence.md)的崩溃恢复规则是完备的，而不仅仅是充分的：被中断的最终轮次被关闭（用合成的 `turn/end {interrupted}`），其真实事件得以保留，且零风险将轮次间上下文混入其中，因为不存在轮次间上下文。`scanLog` 保持简洁（最多一个可能未关闭的最终轮次，绝无散落的轮次间事件），空闲时的后台任务通知在持久化 + 恢复后依然存活。
+
+代价：空闲时调用 `agent.inject()` 现在写入三行日志而非一行；派生的历史中多出一个仅包含注入上下文（无 assistant 输出）的轮次——`deriveMessages()` 已经纯粹按事件类型派生，因此渲染结果完全相同。`injection` 触发器是一个新的磁盘词汇值；与每次 `SessionEventMap`/`TurnTriggerMap` 的新增一样，它属于冻结格式的一部分。轮次内的事件顺序发生了变化（`turn/start` 现在先于 `user/message`），这对任何断言旧顺序的代码可观测——agent loop 自身的测试是唯一的此类消费方。
+
+该规则有意采用生产端强制、开发环境检查的方式，而非读取端容忍的方式：未来的后端（SQLite/WAL）无需额外工作即可继承同样干净的边界，而在轮次外记录事件的插件会在开发环境中大声失败，而非在下次重新加载时静默丢失数据。
+
+轮次内检测到的失败在 `turn/end` 之前记录。后续的 flush 失败没有有效的轮次内位置，因此通过 `agent/error` 和日志报告，而非作为会话事件追加。这保持了回放日志的平衡；持久化的运维诊断需要一个独立的遥测通道。

## Problem
The harness has a concrete `bash` capability seam (`dsh-bash` / `dsh-bash-local` / `dsh-tool-bash`), but filesystem operations are about to be added as model-facing tools without an equivalent seam. If `read`, `write`, and `edit` directly use `node:fs`, the model-facing tool package will own filesystem execution policy, local path resolution, atomic write behavior, text decoding, symlink behavior, and edit semantics all at once.

+# Agent Note: 文件系统能力 seam——ctx.fs、本地后端与面向模型的文件系统工具
+
+Status: implemented
+
+[English](2026-06-17-filesystem-capability-seam.md) | 中文
+
+## 问题
+
+harness 已有一个具体的 `bash` 能力 seam（`dsh-bash` / `dsh-bash-local` / `dsh-tool-bash`），但文件系统操作即将作为面向模型的工具加入，却没有等价的 seam。如果 `read`、`write` 和 `edit` 直接使用 `node:fs`，面向模型的工具包将同时承担文件系统执行策略、本地路径解析、原子写入行为、文本解码、符号链接行为和编辑语义。
+
+这把三个独立变化的关注点耦合在了一起：
+
+1. 文件系统契约：插件可以请求哪些操作。
+2. 后端：当前是本地磁盘，未来可能是沙箱/远程/项目作用域的文件系统。
+3. 消费方接口：面向模型的 `read` / `write` / `edit` schema 与结果格式化。
+
+如果没有 `ctx.fs` 接口，将本地文件系统访问替换为沙箱或远程后端时，即使面向模型的契约应当保持稳定，工具 schema、演示和提示词引导也会被迫变动。这还使权限/沙箱边界更难推理：一个 `cwd` 选项看起来像沙箱，但除非有显式的后端或 `tools/execute` 策略强制隔离，否则它只是一个基础路径。
+
+我们需要文件系统工具在成为公开包（package）接口之前，以与 bash 相同的能力 seam 形态落地。
+
+## 决策
+
+文件系统访问是一个一等的能力 seam，遵循[能力 seam Agent Note](2026-06-13-capability-seams.md)：
+
+1. `@deepseek-ai/dsh-fs`（`packages/fs/fs`）拥有抽象的 `ctx.fs` 服务、文件系统词汇类型，以及 `fs/*` 策略事件词汇。
+2. `@deepseek-ai/dsh-fs-local`（`packages/fs/fs-local`）提供第一个实现，以本地文件系统为后端。
+3. `@deepseek-ai/dsh-tool-fs`（`packages/fs/tool-fs`）通过 `ctx.fs` 提供面向模型的 `read`、`write` 和 `edit` 工具，是分发 `fs/*` 事件的执行器。
+
+消费方包仅依赖接口包，从不依赖 `dsh-fs-local`。需要不同后端的部署只需为 `ctx.fs` 加载不同的提供方，无需改动工具 schema 或面向模型的提示词引导。
+
+读后写/编辑与观测状态策略是第四个包 `@deepseek-ai/dsh-fs-policy`（`packages/fs/fs-policy`），通过 `fs/*` 事件门控贡献，而非挂在 `ctx.fs` 上；加载 `dsh-tool-fs` 的部署同时加载 `dsh-fs-policy` 以获得读后写/编辑能力。本 Agent Note 确立了由三个包构成的 seam；策略从提供方基类拆出的决策由 [拆分文件系统 seam Agent Note](../simplification/2026-06-26-fsspec-style-fs-seam.md) 做出，其以事件门控插件（而非方法服务）实现的方式由 [事件门控 Agent Note](2026-06-26-file-context-as-event-gate.md) 做出。本文已更新为描述最终落地的四包形态。
+
+第一个后端有意仅限本地：`dsh-fs-local` 基于宿主文件系统实现 `ctx.fs`。未来的兄弟后端可在同一接口之后提供沙箱、远程、虚拟或项目作用域的文件系统。
+
+第一个消费方有意仅限文本文件：`dsh-tool-fs` 暴露面向模型的 `read`、`write` 和 `edit` 工具，处理 UTF-8 文本文件。未来的消费方可以添加目录列表、搜索/glob、二进制安全操作、文件监视或更高层的项目操作，只要 `ctx.fs` 上存在所需能力，就无需改动本地后端包。直接目录列表后来由[为文件系统 seam 添加直接目录列举能力](2026-07-03-filesystem-directory-listing-seam.md)添加。
+
+文件系统权限和沙箱并非此拆分所隐含。本地后端从其配置的基目录解析相对路径，但隔离策略是独立的决策：要么由更严格的 `ctx.fs` 实现强制执行，要么由权限/沙箱插件包装 `tools/execute` 并在调用到达消费方之前否决。
+
+读后写/编辑与观测状态属于 `dsh-fs-policy`，而非 `ctx.fs`。通过 `fs/*` 事件门控，策略按不透明 actor 记录版本，并提供可选的变更期望；提供方原子性地强制新鲜度。`dsh-tool-fs` 发出事件但不依赖策略。见[拆分文件系统 seam](../simplification/2026-06-26-fsspec-style-fs-seam.md)和[事件门控插件](2026-06-26-file-context-as-event-gate.md) Agent Note。
+
+## 包拓扑
+
+文件系统 seam 使用与 bash 三件套相同的依赖方向：
+
+```text
+@deepseek-ai/dsh-tool-fs --depends on--> @deepseek-ai/dsh-fs <--depends on-- @deepseek-ai/dsh-fs-local
+ consumer interface implementation
+```
+
+`@deepseek-ai/dsh-fs` 仅依赖 `cordis` 加上来自 `@deepseek-ai/dsh-llm` 的仓库级 `HarnessError` 基类。它声明 `ctx.fs` 键、抽象 `FileSystem` 服务、后端和消费方共享的词汇类型、文件系统错误词汇，以及 `fs/*` 策略事件词汇。它不持有观测状态存储，也不持有 owner 推导形态；事件传递一个不透明的 `object` actor，提供方从不读取它，`dsh-fs-policy` 插件在这些事件之上拥有 owner 推导形态和观测状态存储。
+
+`@deepseek-ai/dsh-fs-local` 依赖 `@deepseek-ai/dsh-fs` 和 `cordis`。它继承 `FileSystem`，将自身注册为 `ctx.fs`，拥有本地后端配置（如基目录），并包含所有直接的 `node:fs` / `node:path` 访问。它不持有观测状态存储——新鲜度是后端铸造、策略插件记录的版本令牌。
+
+`@deepseek-ai/dsh-tool-fs` 依赖 `@deepseek-ai/dsh-fs`、`@deepseek-ai/dsh-tools`、`@deepseek-ai/dsh-system-prompt` 和 `cordis`。它注册面向模型的工具和提示词段落。它禁止导入 `node:fs`、`node:path` 或 `@deepseek-ai/dsh-fs-local`；文件系统执行始终通过 `ctx.fs`。如果实现需要具体的 agent 或会话辅助类型，这些依赖属于 `tool-fs`；它们禁止回漏到 `dsh-fs` 中。
+
+根 `tool-fs` 插件通过组合各工具的注册辅助函数来注册完整的文件系统工具套件（`read`、`write` 和 `edit`）。它注入 `fs`，从不导入实现包。
+
+## `ctx.fs` 契约
+
+`@deepseek-ai/dsh-fs` 拥有一个语义文件系统服务。它比 `readFile` / `writeFile` 更高层，这样 `tool-fs` 就不必重新实现路径解析、版本管理、文本解码、二进制拒绝、分页、原子替换、符号链接行为或字面编辑语义。
+
+该接口涵盖以下语义操作：
+
+- 将模型/插件提供的路径解析为后端定义的目标。
+- 获取目标元数据而不读取文件内容。
+- 从目标读取有界的 UTF-8 文本页。
+- 创建或替换一个 UTF-8 文本文件。
+- 通过字面替换编辑一个已有的 UTF-8 文本文件。
+
+提供方 seam 还携带策略所依赖的新鲜度钩子——但观测状态存储和 owner 推导位于 `dsh-fs-policy` 插件中，而非 `ctx.fs` 上：
+
+- 后端为每个目标铸造一个不透明的 `version` 令牌（在 `stat` 以及每次读取/变更结果中）。
+- `writeText`/`editText` 接受一个可选的版本期望：省略它表示无条件的裸提供方变更；提供它则在后端的原子临界区内守护变更。
+- `dsh-fs-policy` 插件在 `fs/write-intent`/`fs/edit-intent` 上决定该期望，并在 `fs/observed` 上记录观测版本，以它从不透明事件 actor 推导出的 owner 为键（通常是 `exec.agent.session`）。
+
+授权基于版本新鲜度，而非完整/部分视图的区分：任何读取都会记录目标的版本，后续的写入/编辑只要文件仍处于该版本就被授权——因此对第 100-150 行的窗口化读取可以授权对第 120 行的编辑。观测状态存储是 `dsh-fs-policy` 内部的 `WeakMap<owner, Map<targetKey, version>>`；`dsh-fs` 不持有任何此类数据，并将 actor 视为不透明。（本 Agent Note 最初建模了一个带 `full`/`partial` 视图的 `FileState` 缓存放在 `ctx.fs` 上；拆分文件系统 seam 与事件门控两份 Agent Note 将其替换为此处描述的基于新鲜度的策略插件。）
+
+路径解析是显式的，允许异步。本地解析可能只做路径规范化，但沙箱/远程/项目作用域的后端可能需要 I/O 才能将用户提供的路径解析为稳定的目标标识。
+
+解析后的目标必须至少暴露三个概念：
+
+- 原始输入路径，用于诊断。
+- 不透明的 `targetKey`，用于陈旧守护和文件状态查找。本地后端可能使用类似 realpath 的键；远程后端可能使用工作区 URI 或文件 id。消费方禁止解析或假设它是本地绝对路径。
+- `displayPath`，用于面向模型/UI 的输出。根据后端不同，它可能是本地绝对路径、工作区相对路径或远程 URI。
+
+读取和变更结果必须包含不透明的文件 `version`。本地后端从 bigint stat 元数据（`dev`、`ino`、`size`、`mtimeNs` 和 `ctimeNs`）派生令牌，因此同大小重写和 inode 替换都会可靠地使消费方失效；远程后端可以使用 revision id 或类似 hash 的令牌。`dsh-fs-policy` 插件记录版本用于陈旧检查；消费方可以展示相关元数据但禁止解释版本令牌。
+
+提供方返回已解码的文本：`readText` 返回整个常规文本文件，`streamText` 为大文件流式传输相同的文本语义。两者负责常规文件检查；有界的行/输出处理不是它们的职责——行窗口化、带行号渲染和总行数统计位于执行器（`dsh-tool-fs`）中，执行器通过 `ctx.fs` 读取并渲染面向模型的窗口。提供方负责 UTF-8 解码和二进制/NUL 拒绝；它不知道行窗口或视图。
+
+观测状态记录不在 `ctx.fs` 上：成功读取后，执行器发出 `fs/observed`，`dsh-fs-policy` 插件为推导出的 owner 记录 `{ version }`。没有 `full`/`partial` 视图——任何窗口的读取都记录版本，新鲜度（而非视图完整性）授权后续的写入/编辑。
+
+全文件写入创建或替换 UTF-8 文本文件。后端在支持且有文档说明时可以创建父目录。已有的非常规目标被拒绝。`writeText` 接受一个可选期望：`createIfAbsent` 创建缺失的目标并拒绝已存在的（报 `FS_NOT_OBSERVED`，这是策略为未观测 owner 使用的路径）；`replaceIfVersion` 仅在目标处于观测版本时替换，否则报 `FS_STALE_VERSION`；省略期望则为无条件的裸提供方创建或覆盖。策略插件根据 owner 的观测状态选择提供哪个期望。
+
+字面编辑是提供方原语（`editText`），而非在 `tool-fs` 中由读取加写入组合而成。字面匹配、重复匹配拒绝、CRLF 保留、二进制拒绝、可选的陈旧版本检查和原子读-改-写必须一起留在后端的变更临界区内。`editText` 接受相同的可选版本期望；陈旧检查在字面匹配之前运行，因此基于旧读取的编辑会报 `FS_STALE_VERSION`。远程后端可以将编辑实现为原生的 compare-and-edit 操作；消费方不强制本地风格的组合。
+
+策略插件（而非 `ctx.fs`）对先前观测进行门控：`edit` 要求 owner 有先前观测（否则报 `FS_NOT_OBSERVED`），记录的版本作为 CAS 基础传给 `editText`。在策略插件缺席时，`ctx.fs` 本身是一个完整的无约束 seam（无条件写入/编辑）；工具从不与策略方法耦合。
+
+文件系统契约失败以 `FsError extends HarnessError` 抛出，工具注册表将其转换为带结构化 `{ name, code }` 元数据的 `isError` 工具结果。`dsh-fs` 拥有此词汇，而非由每个工具各自发明消息。错误码包括 `FS_NOT_FOUND`、`FS_NOT_TEXT`、`FS_STALE_VERSION`、`FS_NOT_OBSERVED`、`FS_NOT_REGULAR_FILE`、`FS_AMBIGUOUS_EDIT`、`FS_EDIT_NOT_FOUND` 和 `FS_ABORTED`。（早期草案包含 `FS_PARTIAL_OBSERVATION`；基于新鲜度的授权没有 partial/full 区分，因此已删除。目录列表相关的错误码后来由[为文件系统 seam 添加直接目录列举能力](2026-07-03-filesystem-directory-listing-seam.md)添加。）

+`@deepseek-ai/dsh-tool-fs` 是面向模型的消费方。它拥有工具名称、JSON Schema、模型边界的参数校验、提示词段落和结果格式化。它不拥有文件系统执行。
+
+第一个工具套件包含：
+
+- `read`：检查一个 UTF-8 文本文件并返回带行号的内容与分页引导。
+- `write`：创建或完全替换一个 UTF-8 文本文件。
+- `edit`：通过替换字面文本更新一个已有的 UTF-8 文本文件，默认要求唯一匹配，并允许显式的全部替换模式。
+
+每个工具遵循相同的执行形态：
+
+1. 校验并规范化模型参数。
+2. 调用相应的 `ctx.fs` 操作。
+3. 将结果格式化为面向模型的 `ContentBlock[]`。
+4. 让抛出的后端/工具错误流经 `ToolRegistry.execute()`，由其转换为 `isError` 工具结果。
+
+该包通过 `ctx.systemPrompt.section(...)` 注册提示词引导，通过 `ctx.tools.register(...)` 注册 schema。工具 schema 仍通过 `SystemPrompt.assemble()` 和 `ToolRegistry.schemas()` 流入正常的提示词组装路径；无需改动 agent loop（智能体循环）。
+
+工具包在后端变化时保持面向模型的契约稳定：本地后端和远程后端内部可能以不同方式解析路径，但 `read` / `write` / `edit` schema 不会仅因后端变化而改变。
+
+默认部署要求在用 `write` 或 `edit` 更新已有文件之前先 `read`。`tool-fs` 不通过检查是否运行过名为 `read` 的工具来实现这一点：它分发 `fs/write-intent`/`fs/edit-intent` 事件（将执行上下文作为不透明 actor 传递），`dsh-fs-policy` 插件推导 owner、对先前观测进行门控并提供版本期望。任何窗口化读取都能授权后续的写入/编辑，只要文件未变。用 `write` 创建新文件不要求先前观测。
+
+根插件通过组合各工具的注册辅助函数来注册完整套件。它注入 `fs`、`tools` 和 `systemPrompt`。
+
+## 测试
+
+测试遵循包边界，而不仅是用户可见的工具：`dsh-fs` 中的服务 seam；`dsh-fs-local` 中通过 `ctx.fs` 接口测试的真实文件系统行为（解析、符号链接、流式传输、二进制/UTF-8 拒绝、无条件和版本守护的写入、字面编辑语义、行尾保留、结构化 `FsError` 错误码）；`dsh-tool-fs` 中基于真实本地提供方的消费方接口（只 mock 模型/时钟，从不 mock 协作者）；以及通过 `ctx.tools.execute()` 在有和没有 `dsh-fs-policy` 的情况下进行集成测试，通过从磁盘回读文件来验证世界状态，既不信任规范值，也不信任渲染内容。观测状态/owner 推导策略在 `dsh-fs-policy` 中测试，不在此处。
+
+本仓库曾踩过的防御性模式类别被直接固定：
+
+- **原子写入临时文件安全。** 写入/编辑通过目标旁边一个私有随机 `0700` 目录中的独占 owner-only（`'wx'`、`0o600`）临时文件暂存，失败时清理，最后原子 rename——与 bash 溢出文件规则一致，因为可预测的 world-readable 临时路径招致符号链接竞争和信息泄露。测试断言权限，并断言已存在的临时路径不会被覆盖；此原语是 seam 的常设要求。
+- **通过符号链接的 `targetKey` 同一性。** 两个输入路径解析到同一 realpath 时共享一个观测状态条目：通过路径 A 的 `read` 满足通过符号链接路径 B 的 `edit` 的读后编辑守护，通过一个路径的陈旧写入可通过另一个路径检测到。
+- **并发/陈旧竞争。** 对同一目标的两个并发写入/编辑操作确定性地收敛——一个成功，另一个被 `FS_STALE_VERSION` 拒绝——成功的编辑刷新记录状态，使同一 owner 的下一次编辑可以继续。
+- **HMR（热模块替换）安全与 dispose（资源释放）。** dispose 后端的 fiber 会撤回 `ctx.fs` 提供方；后续的提供方以无继承状态启动。
+
+## 曾考虑的替代方案
+
+- **面向模型的工具直接基于 `node:fs`**：工具包将同时承担执行策略、路径解析、原子写入、文本解码和编辑语义，耦合问题部分所列的三个独立变化的关注点，且任何后端替换都会搅动 schema。
+- **单一合并包 `dsh-fs-tools`**：seam 之前的形态；以与 bash 相同的接口/实现/消费方拆分理由否决，且合并名称从未成为公开接口。
+- **观测状态放在 `ctx.fs` 上**：本 Agent Note 最初落地的形态；被 [拆分文件系统 seam Agent Note](../simplification/2026-06-26-fsspec-style-fs-seam.md) 和 [事件门控 Agent Note](2026-06-26-file-context-as-event-gate.md) 取代：沙箱/远程后端不应继承面向模型的观测策略，因此提供方只保留版本令牌和可选的版本守护变更。
+
+## 后果
+
+**`cwd` 可能被误认为沙箱。** 本地后端的基目录是解析默认值，而非自动的隔离边界。如果需要隔离，必须由后端契约或 `tools/execute` 上的权限/沙箱插件强制执行。
+
+**接口可能变得过于本地化。** 如果 `ctx.fs` 返回 `absolutePath` 之类的字段，远程、沙箱或虚拟后端会变得尴尬。契约应暴露显示元数据，而不要求消费方理解宿主路径。
+
+**接口可能变得过于薄。** 如果 `ctx.fs` 只镜像 `node:fs` 原语，`tool-fs` 将重新实现二进制检测、分页、原子写入和编辑语义，重新制造本 Agent Note 试图避免的耦合。
+
+**编辑语义天然易受竞争影响。** 字面编辑是读-改-写操作；守护手段是后端的原子变更临界区加上可选的版本期望，因此并发编辑确定性地收敛——一个赢，另一个得到 `FS_STALE_VERSION`。
+
+**观测状态不属于 `ctx.fs`。** 记录执行上下文看到了什么是工作流策略，而非原始文件系统 I/O。本 Agent Note 最初将其放在文件系统 seam 内部；拆分文件系统 seam Agent Note 随后确立了沙箱/远程后端不应继承面向模型的观测策略，并将其移入 `dsh-fs-policy` 插件。提供方 seam 只保留写入/编辑安全在存储层真正需要的东西——后端铸造的版本令牌和可选的版本守护变更——而策略插件拥有 owner 推导、观测状态和基于 `fs/*` 事件的读后编辑门控。
+
+**`resolve` 然后操作的形态每次调用多一次往返。** 每个工具可能先将路径解析为 `FsTarget`，再以单独的 `ctx.fs` 调用发起读取/写入/编辑。对本地后端来说这可以忽略（解析是内存中的路径规范化），但远程/沙箱后端可能将每步变成独立请求，使单次 `read` 变为两次网络往返。往返开销重要的后端可以在内部缓存或折叠解析，同时保持可观测契约不变。
+
+**观测状态持久化被推迟。** 观测状态存在于内存中（`dsh-fs-policy` 内部的 `WeakMap`），因此恢复的会话保守地要求文件在写入/编辑前重新读取，直到未来的会话事件或持久化机制使观测可回放。
+
+**错误码成为 seam 的一部分。** `FsError` 错误码使陈旧版本和观测失败可通过既有的结构化错误分类体系进行机器路由。代价是 `dsh-fs` 从 `dsh-llm` 导入共享的 `HarnessError` 基类；该依赖是有意为之且限于错误词汇。
+
+**包拆分的成本前置。** 三包拆分在只有一个后端时就增加了样板代码。这是有意为之：文件系统访问是可能的沙箱/远程边界，在面向模型的工具发布后再改包接口代价更高。

+# Agent Note: Agent 生命周期与所有权 seam
+
+Status: implemented
+
+[English](2026-06-18-agent-lifecycle-and-ownership-seams.md) | 中文
+
+## 问题
+
+ACP（Agent Client Protocol）与 tool-bash 的若干限制是同一个缺失 seam 的症状：插件可以通过 `ctx.agents` 创建或恢复 agent（智能体），但无法独立拥有和 dispose（资源释放）单个 agent，而长时间运行的 bash 任务在执行器中也没有稳定的所有者。ACP 在断连时中止并等待 agent，却无法仅注销该会话的 agent；`session/cancel` 无法取消已入队但尚未开始的工作；`tool-bash` 将任务所有权保存在插件本地的 `Map` 中，因此一次 HMR（热模块替换）重载就可能让旧任务看起来无主。
+
+## 决策
+
+三个 seam：队列感知的取消、`AgentHandle` 释放器，以及 bash 所有者令牌。
+
+### 1. 队列感知的 `Agent.cancel(cause?)`
+
+`Agent` 接口新增 `cancel()` 动词——唯一的公开停止原语。（它最初与范围更窄、仅作用于步骤的 `abort()` 一同交付；后者后来因无人使用而移除，使 `cancel()` 成为唯一公开的停止工作方式。）它清空 inbox 的 queued + steering FIFO，在存在活跃轮次时中止它，并保留一个不带 cause 的 pre-run 标记，使在取得所有权前被取消的提示词永不运行，而后来的提示词仍保持独立。有效调用会在清空或中止前发出 `agent/cancel-requested`，携带类型化的 `user | parent` cause；空闲取消不发出任何事件，也不会使下一条提示词搁浅。`whenIdle()` 会在取消后达到完全停稳，ACP 的 `session/cancel` 映射到 `user`。[显式轮次取消决策](2026-07-16-explicit-turn-cancellation.md)拥有当前的 cause、signal 生命周期与协作式结算契约。
+
+### 2. `AgentHandle` 异步释放器
+
+`ctx.agents.create`/`resume`（以及 `AgentFactory` 接口）返回 `AgentHandle = { agent: Agent; dispose(): Promise<void> }`。释放器是一种**消费方能力**——仅持有裸 `Agent` 的注册表观察者无法将其拆除。调用方 fiber 和已注册的 factory 提供方是结构上的共同所有者：调用方卸载强制结构化所有权，而提供方卸载必须停止旧实例，因为其实例作用域的依赖 surface 通过该提供方解析。三条路径都会进入同一个 memoize 的拆除过程：停止循环、等待其退出与空闲刷写完成（完全停稳，而非仅把状态翻转为 `disposed`）、分离 agent、分离其会话，然后解除其 scope。每个公开 ID 在其精确注册表条目分离时变得可复用；不存在独立的保留释放阶段。由配置创建的 agent 已归 `AgentLoop` fiber 所有（handle 被丢弃）。ACP 在其 `SessionRecord` 中保存每个全新会话的释放器，并在断连或插件拆除时运行它，因此单纯的客户端断连不会留下已注册 agent 或会话存储条目。在与关闭的竞态中落败的创建流程会 dispose 其尚未发布的 handle。
+
+**拆除顺序对持久性至关重要**，实现将会话生命周期折叠进 agent 的单个复合 Cordis effect（`SessionStore.prepare`/`enter`/`announce`，取代兄弟 effect 拆分）。fiber 卸载会并发释放兄弟 effect（`Promise.all`），这会让会话存储的 append 发布钩子移除与循环关闭时的 `session/flush` 竞争，从而丢失关闭的 `turn/end`；在一个 effect 内，释放器作为有序的 LIFO 链运行（停止循环 + `await agent.done` 在会话分离之前），因此无论 handle 的 `dispose()` 还是 fiber 卸载，都会捕获循环的最终刷写。被隔离的 `agent/disposed` 和 `session/disposed` 通知无法拒绝该链或跳过后续拆除。
+
+### 3. Bash seam 中的所有者令牌
+
+后台任务所有权从 `tool-bash` 插件本地的 `Map<string, Agent>` 移入执行器。`BashExecRequest` 新增可选的 `owner?: string`；解析后的 `BashExecSpec` 将其作为必需但可空的 `owner: string | undefined` 携带（被遗忘的 owner 是可见的 `undefined`，而非静默缺失的属性）。执行器把 token 存在任务上，并通过新的 `BashExecutor.ownerOf(id): string | undefined` seam 暴露它（不放在公开的 `BashTask` 上——只有一条读取路径，没有冗余 API）。`tool-bash` 完全删除其 `Map`：它在 `start` 时将 `exec.agent?.id`（共享的注册表/会话 id）盖章为 owner，`bash_output`/`bash_kill` 则以 `!== undefined` 语义把 `ctx.bash.ownerOf(id)` 与调用方 token 比较（空字符串 token 仍是真实 owner）。完成通知通过扫描 `ctx.get('agents')?.list()` 查找 `agent.id === ownerToken` 的存活 agent（经 `ctx.get` 读取——`onTaskDone` 运行在 bash fiber 这一外部 fiber 上，直接使用 `ctx.agents` proxy 会抛异常）。由于所有权现在存活在执行器的任务上（随 `dsh-bash` fiber dispose），它能跨越 `tool-bash` HMR 重载，关闭旧的 `XXX(tool-bash-owner-hmr)` 缺口。（`onTaskDone` 监听器仍受 `tool-bash` 的 `apply` effect 约束，因此落在重载间隙的完成仍会丢失一条通知——既有的重载间隙丢失——但所有权隔离本身已经不受 HMR 影响。）
+
+## 验证
+
+以下不变式已经成立，并由测试固定：
+
+- ACP 断连或插件拆除后，任何由桥接层拥有的会话都不留下已注册 agent 或会话存储条目，包括与连接关闭竞争的创建流程。
+- 已入队的提示词启动前执行 `session/cancel`，能阻止该提示词运行；后来接受的提示词仍是独立的已入队轮次。
+- `tool-bash` HMR 重载不会使另一个会话能够读取或终止已有的后台任务（所有权保留在执行器上）。
+- 既有的非 ACP 演示无需显式管理 handle 仍能工作；由配置创建的 agent 仍归 `AgentLoop` 插件 fiber 所有。
+
+## 会话所有者令牌在存活 agent 中唯一
+
+bash 所有者 token 比较依赖共享的 `Agent.id`/`SessionId` 在存活 agent 中唯一。并发的同 ID 操作可以都私下准备，但发布会依次进入会话和 agent；`SessionStore.enter()` 拒绝重复的存活会话 id，每个失败事务都回滚自己的私有状态。因此程序化调用方无法发布两个共享同一会话 token 的存活 agent。访问*策略*（token 比较）留在消费方 `tool-bash`；bash seam 只存储不透明的 `owner` 字符串且从不解释它——这是正确的接口/实现/消费方拆分。
+
+## 曾考虑的替代方案
+
+- **公开的 `BashTask.owner` 字段**而非 `BashExecutor.ownerOf(id)` seam：否决。一条读取路径即可，无需冗余 API。
+- **为 agent 的会话生命周期使用兄弟 Cordis effect**：否决。fiber 卸载时并发释放兄弟 effect（`Promise.all`），store 拥有的 append 发布钩子的移除与循环的关闭 `session/flush` 产生竞争；单一复合 effect 的有序 LIFO 链才能在两条释放路径上都捕获关闭的 `turn/end`。
+- **在 `cancel()` 之外另设一个仅中止步骤的 `abort()`**：最初发布过，后因无人使用而移除；`cancel()` 是唯一的公开停止原语（见[公开停止接口 Agent Note](../simplification/2026-06-20-public-agent-stop-surface.md)）。
+
+## 后果
+
+本变更有意触及公开接口（`Agent`、`AgentFactory`、bash seam），而非作为 ACP 的局部补丁。同步 `Agent.send()` 的简洁易用性得以保留；异步生命周期路径是增量添加的，供需要它的所有者使用。

+# Agent Note: 会话 surface：事件日志上的有序投影
+
+Status: implemented
+
+[English](2026-06-18-session-surface.md) | 中文
+
+## 问题
+
+事件日志是权威数据源，但历史操纵此前没有持久化的共享机制。如果没有这样的机制，上下文压缩（context compaction）等插件只能通过顺序敏感的监听器改写派生请求，不留溯源信息，且每次新增操纵都要反复修改 `deriveMessages()`。
+
+## 决策
+
+新增一个 **surface**：事件 seq 的派生、缓存有序投影（即产出 LLM（大语言模型）消息的事件子集），通过事件日志中的 `surfaceOp` 标记维护。
+
+### `SessionEvent` 新增两个顶层字段
+
+每个 `SessionEvent` 获得两个可选字段（结构性元数据，与 `seq`/`time` 同级）：
+
+- **`sourceEventSeqs?: number[]`**：作为溯源来源的事件 seq 编号（例如构成 `assistant/message` 的各 `assistant/chunk` 的 seq，或被压缩标记遮蔽的 surface 节点）。出现的 `[]` 只在 `assistant/message` 上有效，表示已知为空的提供方流；在该事件上省略字段表示旧数据或未记录的溯源。其他 surface 事件一旦出现此字段，就必须是非空列表。溯源是核心设计原则；没有它，replace-range 操作在回放时无法被验证。
+- **`surfaceOp?: SurfaceOp`**：该事件如何进入 surface。非 surface 事件不携带此字段。
+
+### SurfaceOp：两种操作
+
+```ts
+export type SurfaceOp =
+ | 'append' // normal tail append
+ | { op: 'replace'; start: number; end: number } // shadow [start, end] inclusive
+```
+
+1. **Append**：在尾部追加新事件的 seq。`user/message`、`assistant/message`、`tool/result`、`context/message`、`steering/message` 使用此操作。agent loop（智能体循环）在所有此类追加上传入 `surfaceOp: 'append'`，并在适用时记录 `sourceEventSeqs`：每个成功的 `assistant/message` 都记录完整的 `assistant/chunk` 来源集合（包括 `[]`），而 `tool/result` 记录其 `tool/call` 来源。
+
+2. **Replace**：移除从 `start` 到 `end`（两端包含）的条目，并在其位置插入新事件的 seq。`start` 和 `end` 都必须存在于当前 surface；`start === end` 表示替换单个条目。该事件的 `sourceEventSeqs` 必须包含所有被遮蔽的 surface seq。被遮蔽的事件仍留在日志中，但不再出现在 surface 上。
+
+### SurfaceManager：基于增量，而非全量重建
+
+一个 `Session` 拥有一个 `SurfaceManager`，后者维护事件 seq 的有序 `number[]`。管理器会在提交前校验每个种子或追加候选项而不应用它，然后只处理上次同步之后已经提交的事件，而不重新扫描整个日志。`Session.surface` 通过只读的 `SessionSurface` 契约暴露同一个管理器，因此接纳、派生历史、压缩与工作区上下文共享同一份增量状态。Replace 按数组位置找到两端都包含的端点，并把替换 seq splice 到该范围；不会用第二个管理器、链接对象或 seq 到节点的 map 来重复表达顺序。
+
+无新事件时增量处理为 O(1)，有新事件到达时为 O(新事件数)。
+
+`deriveMessages()` 在存在 surface 标记时使用 surface，对没有标记的会话回退到既有的线性扫描（向后兼容）。
+
+### 持久化
+
+新字段作为顶层 JSON 属性序列化。JSONL 后端无需任何改动：`JSON.stringify`/`JSON.parse` 透明地保留一切。SQLite 后端的 `events` 表新增两个可空 TEXT 列（`source_event_seqs`、`surface_op`）。磁盘上的 `SCHEMA_VERSION` 递增以反映列集变化，并且按照预发布的 bump-and-reject 策略，由其他构建写入的数据库在打开时被拒绝而非迁移（没有需要升级的持久化用户数据）。会话格式 `version` 固定为 `SESSION_FORMAT_VERSION = 0`（「不稳定/预发布」立场）：可选的 surface 字段被吸收而不递增版本号。
+
+### 崩溃恢复
+
+`repair.ts` 模块在崩溃后为孤立的工具调用合成 `tool/result` 闭合事件。这些闭合事件携带 `surfaceOp: 'append'` 和指向孤立 `tool/call` 事件的 `sourceEventSeqs`，确保重建的 surface 有效。
+
+### 不变式
+
+`Session` 在始终启用的 seed/append 边界校验 `sourceEventSeqs` 与 `surfaceOp`：只有 `assistant/message` 可以使用空的溯源列表；引用必须唯一、更早且已知；替换端点必须存在于 surface 顺序中；溯源必须覆盖每个被遮蔽的节点。这些是单记录接纳与存储投影规则，不是可选的不变式服务贡献。
+
+每个 surface 可达事件都必须携带 `surfaceOp`，否则它将从派生历史中消失。类型化的 `append` 重载对字面事件类型强制执行此规则；`append` 和种子构造函数中的运行时检查覆盖宽化联合类型和加载的日志。按照预发布格式策略，无效的种子被拒绝而非升级。
+
+## 曾考虑的替代方案
+
+- **逐插件的 `agent/request` 包装**（surface 之前的历史操纵模式）：监听器排序脆弱、无法持久记录改动内容，且每种新操纵都迫使核心 `deriveMessages()` 再次修改。
+- **半开区间 `[start, endExclusive)` 的 replace 范围**：否决。端点由 surface 事件 seq 命名，单条目替换（`start === end`）在闭区间语义下读起来更自然。
+- **链接节点对象加 seq map**：否决。生产代码不读取前驱链接，唯一的后继用途就是数组中的下一个位置，而替换本来就需要线性 `indexOf` 查找。单个 seq 数组在保留相同渐进复杂度的同时，只留下一个需要校验的表示。
+- **脏标记后全量重建**替代增量处理：在会话生命周期内为 O(N²)，每次单事件追加都要重新扫描所有先前事件。
+
+## 后果
+
+- **`packages/core/session`**：`surface.ts`（`SurfaceManager`）维护一个用于候选接纳和实时投影的有序 seq 数组；`SessionSurface` 是其只读公共视图。`SurfaceOp`/`SurfaceIntent` 与顶层会话事件字段记录条目如何加入它。`append()` 要求 surface 事件携带 `SurfaceIntent`，`deriveMessages()` 以遍历 surface 作为唯一派生路径，`repair.ts` 则发出 surface 感知的闭合事件。种子构造函数拒绝缺少 `surfaceOp` 标记的 surface 可达种子事件（见「不变式」一节）。
+- **`packages/core/agent-loop`**：所有 surface 可达的追加操作传入 surface 选项。收集分片 seq 用于 `assistant/message` 溯源；捕获 `tool/call` seq 用于 `tool/result` 溯源。
+- **`packages/session-persistence/session-persistence-sqlite`**：`events` 表新增两个可空 TEXT 列（`source_event_seqs`、`surface_op`）；`SCHEMA_VERSION` 递增（bump-and-reject，无迁移）。
+- **`packages/session-persistence/session-persistence-jsonl`**：无需改动。
+- **`packages/session-persistence/session-persistence`**：抽象接口不变。
+
+Surface 是未来历史操纵的基础。压缩或 tool-result-prune 插件追加一个既有的消息产出事件类型（例如一条携带摘要的 `user/message`），附带 `surfaceOp: { op: 'replace', start, end }` 和覆盖被遮蔽条目的 `sourceEventSeqs`——新事件在 surface 上取代该范围的位置，而插件自身的 trace 事件（如 `compaction/start`、`compaction/end`）不进入 surface。回放以确定性方式保留该决策。
+
+一次 `tool/result` 替换只能改写当前的一个 `tool/result`，并且必须保留除 `content` 以外的每个数据字段。Session 接纳会与位置范围和溯源校验一起强制这条规则，不依赖可选的诊断插件。

## Problem
`dsh-session-persistence-jsonl` and `dsh-session-persistence-sqlite` intentionally prove the same `SessionPersistence` contract over different storage media, but their write-path orchestration was duplicated: per-session state, `session/created` adoption, backend-specific prefix reads, write-behind control, per-id operation serialization, HMR seeding, and dispose drains. The pure seed-prefix collision and serializability guards had already moved into the seam package; the remaining orchestration was still correctness-heavy and received the same fixes twice. Only the storage primitives (write bytes vs. INSERT rows) differed.

+# Agent Note: 共享持久化写入协调器
+
+Status: implemented
+
+[English](2026-06-18-shared-persistence-write-coordinator.md) | 中文
+
+## 问题
+
+`dsh-session-persistence-jsonl` 与 `dsh-session-persistence-sqlite` 有意在不同存储介质上证明同一份 `SessionPersistence` 契约，但它们重复实现了写入路径编排：每会话状态、`session/created` 接管、后端特定的前缀读取、write-behind 控制、按 id 串行执行操作、HMR（热模块替换）种子注入与 dispose（资源释放）排空。纯粹的种子前缀碰撞检查与可序列化守卫已迁入 seam 包；剩余的编排仍然对正确性要求很高，且同样的修复被应用了两次。唯一的差异在于存储原语（写字节 vs. INSERT 行）。
+
+## 决策
+
+将一个后端无关的 `PersistenceCoordinator` 提取到 `dsh-session-persistence` 中。协调器统一拥有编排逻辑；每个第一方后端组合一个协调器实例（`new PersistenceCoordinator(ctx, this)`），实现一个小型 `PersistenceBackend` 钩子接口，并将其有状态的公开方法（`create`/`append`/`load`/`inspect`）委托给协调器。由后端拥有的元数据与修订版本列举会绕过协调器。
+
+组合，而非继承。协调器是后端持有的具体类，不是后端继承的基类。本 Agent Note 的风险——「协调器不得让非常规后端与继承层级作斗争」——由此规避：后端只暴露钩子，无法触及协调器的私有编排状态。第三方后端仍然可以完全不使用协调器、直接实现抽象服务，包括供读模型使用、不修改状态的 `inspect` 契约。
+
+协调器为每个确切的存活 `Session` 持有一个控制器；该控制器统合初始化、待处理事件与共享 flush promise。每个 `session/event` 都会立即启动排空，而 `session/flush` 只观察完全停稳，不会发起常规写入路径。[flush 控制器简化](../simplification/2026-07-23-collapse-persistence-flush-state.md)定义该生命周期。
+
+协调器通过 `session/disposed` 退役会话：它等待控制器完成初始化和当前 flush，串行执行最后一次排空，且仅在成功后才移除控制器与其拥有的每 id 状态。失败时保持控制器可被找到，以供后端 teardown（拆除）重试。每个 id 的已结算链尾仅在其仍是当前链尾时才移除自身，因此旧操作完成后不会抹除同一 id 的新操作。后端 teardown 会注销写入路径监听器、flush 每个剩余的控制器、等待所有按 id 串行化的操作，最后关闭后端。
+
+### 钩子接口（`PersistenceBackend<TornMarker>`）
+
+五个必需成员加一个可选的生命周期钩子，构成协调器与存储之间唯一的边界：
+
+- `name`——后端标签，用于 dispose 失败时的 `AggregateError`。
+- `loadStored(id)`——按 id 跨所有存储范围读取一个已存储前缀（JSONL 的所有项目目录；SQLite 的 id 全局唯一）。恢复/加载、不修改状态的检查、存活会话接管与创建碰撞探测共用此查找。协调器会断言返回的 id，并在修复或发布状态之前拒绝已存储记录与存活会话的 cwd 不匹配。
+- `appendBatch(meta, events, isMaterialized)`——持久追加一个连续批次，在尚未物化时原子地惰性物化会话（物化写入与首批事件必须一起提交——崩溃不得留下一个已物化但为空的会话；这就是为什么没有单独的 `materialize` 钩子）。
+- `commitRepair(meta, tornMarker, closers)`——使崩溃修复持久化：截断损坏的尾部（当且仅当 `tornMarker !== undefined`）并追加 `closers`。**不要求原子性**——JSONL 合理地分两步 fsync（先截断再追加），SQLite 在一个事务中完成 DELETE+INSERT。用于 `load`（截断 + 合成 closers）和 live-adoption（仅截断，`closers = []`）。
+- `list()`——列出所有已存储的元数据。
+- `close?()`——可选的生命周期清理（SQLite 关闭 db 句柄；JSONL 省略），在 dispose effect 中于排空至完全停稳之后被 await，因此 close 失败不会掩盖排空错误。
+
+### 不透明的 torn marker
+
+保持 seam 整洁的唯一设计选择：崩溃修复中「损坏尾部在哪里」的 token 对协调器是不透明的。协调器计算合成 closers（它拥有来自 `dsh-session` 的 `interruptedTurnClosers`），但它只测试 `tornMarker !== undefined` 并将值原样传回 `commitRepair`——从不检视其内容。每个后端选择自己的 marker 类型：JSONL 携带要截断到的字节偏移，以及从不完整最终帧中解码出的任何完整事件；SQLite 则携带要从其开始删除的 seq。协调器因此既不了解字节长度，也不了解帧恢复状态。
+
+## 测试
+
+共享的 `runPersistenceContract`（公开 API 契约）为每个后端运行，并证明在 `load` 执行恢复之前，`inspect` 会保持被中断的日志与修订版本不变。`runCoordinatorContract`（`tests/coordinator-contract.ts`）通过内存参考实现、JSONL 与 SQLite 覆盖接管、HMR、碰撞、会话与后端 dispose 排空，以及崩溃尾部修复。协调器专属测试覆盖立即执行的后续批次、存活控制器清理、同 id 链尾竞态、排空失败重试与关闭顺序。各后端自身的测试规格只保留存储机制。每个真实后端都有一个经由协调器的崩溃尾部修复测试，以覆盖不透明 marker 分支，因为契约中的崩溃用例会产生合成 closers，却不会产生 torn marker。
+
+## 曾考虑的替代方案
+
+- **后端继承的基类**——否决，改用组合：后端只暴露钩子，无法触及协调器的私有编排状态，且第三方后端仍可完全不使用协调器、直接实现抽象服务。
+- **更宽的钩子面**——每个候选钩子都被折叠掉：没有限定存储范围的实时查找，因为 `loadStored` 加上协调器的 cwd 检查即可维持碰撞边界；没有存储定位器泛型，因为经验证的 JSONL 元数据可还原其路径，而 SQLite 已按 id 绑定；没有单独的 `materialize` 钩子，因为首批事件必须与物化原子提交；没有单独的创建碰撞探测，因为它就是 `loadStored(id) !== undefined`；`list()` 也不经由协调器透传，因为列举不需要任何编排。
+
+## 后果
+
+协调器增加了一层间接、一个不透明的 torn marker 和脱离会话生命周期的退役任务，但将此前每个后端重复的、对正确性要求很高的编排逻辑集中到一处。会话 dispose 仍是仅观察事件，因此会话所有者不会等待持久化退役；协调器会收容失败、在存活控制器中保留待处理事件，并以后端 teardown 为完全停稳边界。其钩子面保持窄小：标识校验、接管、碰撞检查与不修改状态的检查共用 `loadStored`；物化保持在 `appendBatch` 内原子完成；列举绕过协调器。读模型使用 `inspect` 而非 `load`，因此观察已持久化但仍开放的轮次时，不会因提交中断 closers 而与新的存活所有者产生竞态。新后端只需实现存储原语，而无需复制立即写入生命周期。

+# Agent Note: 在所有应有之处使用 branded ID
+
+Status: implemented
+
+[English](2026-06-20-branded-ids.md) | 中文
+
+## 问题
+
+harness 使用 `Branded<B> = string & { readonly [BRAND]: B }` 机制，为 `CallId`（`packages/llm/llm/src/brand.ts`）和 agent/会话共享的 `SessionId`（`packages/core/session/src/types.ts`）做 brand 处理；该机制由纯类型包（package） `@deepseek-ai/dsh-brand` 拥有，位于 `packages/util/brand/`，见其 [README](../../../../packages/util/brand/README.md)，并为每个类型提供零开销的 cast 工厂。`dsh-brand` 还声明了治理策略：*「Branding 用于跨包边界且可能被混淆的 id；不是每个 string 都需要 brand。」* 这条策略是正确的；问题在于它只落实了一半。两处缺口使得结构相同但语义错误的 string 今天仍能通过类型检查器。
+
+**缺口 1：bash seam 中未 brand 的跨边界 ID。** 后台 task id 是普通 `string`：`BashTask.id: string`（`packages/bash/bash/src/types.ts`），作为 `string` 贯穿整个执行器 seam（`packages/bash/bash/src/index.ts` 中的 `BashExecutor.get`/`ownerOf`/`readOutput`/`kill(id: string)`），再由面向模型的工具以 `string` 校验并传递（`validateTaskId`、`assertTaskAccess`、`packages/bash/tool-bash/src/index.ts` 中 `task_id` 的 schema 参数）。它由每执行器计数器生成——`packages/bash/bash-local/src/index.ts` 中的 `` `bash-${this.nextTaskId++}` ``——其形状与 `SessionId` 的默认值**完全相同，都是 `name-N`**（`packages/core/session/src/index.ts` 中的 `` `session-${++counter}` ``）。bash task id 和会话 id 在调用点轻易就能互换，而编译器毫无反应。这是用户询问的核心案例，并且它是面向模型的 id（模型会把 `task_id` 传回 `bash_output`/`bash_kill`），所以该混淆可由不受信任的输入触达。
+
+bash **owner token** 是相关的子情形：`BashExecRequest.owner?: string` 和 `BashExecSpec.owner: string | undefined`（`packages/bash/bash/src/types.ts`）被文档描述为刻意*不透明*的隔离键，但在所有实际调用方中，该值就是所属 agent（智能体）共享的 `Agent.id`/`SessionId`（`callerToken = (exec) => exec.agent?.id`，位于 `packages/bash/tool-bash/src/index.ts`），只是披着另一个 seam 本地名称。它被用于访问控制比较（`owner !== callerToken(exec)`），因此一个不匹配但类型正确的 string 在此处就是跨会话隔离 bug，而当前类型系统无法捕获。这正是[统一 agent/session 标识决策](../simplification/2026-06-20-unify-agent-and-session-id.md)覆盖的共享 id 别名。
+
+**缺口 2：*已经 brand* 的 ID 在 seam 处被侵蚀。** 就连 `CallId` 和 `SessionId` 也恰好在最容易混淆的地方退化为裸 `string`：注册表/store 键类型和公开方法参数。代表性位置包括会话存储、agent 注册表（二者都以共享的 `SessionId` 为键）、工具展示层的 call-id map、ACP 的会话记录，以及持久化协调器。在集合键处丢弃 brand，会让既有 brand 在查找时毫无价值；它们的价值只实现了一部分。
+
+## 决策
+
+纯类型变更。Brand 是零开销 cast；运行时行为、序列化、比较和协议格式（wire format）均不变。工作分三部分，全部遵循既有的「不是每个 string 都需要」策略。
+
+- **为 bash task id 加 brand。** 在 `packages/bash/bash/src/types.ts`（*拥有*该 id 的包）中添加 `BashTaskId = Branded<'BashTaskId'>` 及其同名工厂，从 `@deepseek-ai/dsh-brand` 导入 `Branded`，方式与 `SessionId` 完全一致。brand 原语位于无依赖的 `dsh-brand` 工具包中，正是为了让 `dsh-bash` 仅依赖它就能为自己的 id 加 brand，而无需引入 `dsh-llm`（或 `dsh-session`）来获取 `Branded`。将其贯穿 `BashTask.id`、`BashExecutor` seam 方法（`get`/`ownerOf`/`readOutput`/`kill`）、`dsh-bash-local` 中的生成点（在创建时对计数器输出做一次 brand），以及 `dsh-tool-bash` 的校验/访问面（`validateTaskId` 返回 `BashTaskId`；`task_id` 在模型 string 到达的工具边界处被 brand）。
+
+- **铸造独立的 `OwnerToken` brand。** 在 `packages/bash/bash/src/types.ts` 中添加 `OwnerToken = Branded<'OwnerToken'>`；将 `BashExecRequest.owner` / `BashExecSpec.owner` / `BashExecutor.ownerOf` 的类型标注为 `OwnerToken | undefined`。`dsh-tool-bash` 消费方在边界处将 agent 共享的 `id`（`SessionId`）cast 为 `OwnerToken`——这是两套词汇唯一交汇的地方。bash seam 从不导入 `dsh-session`。（理由见下一节。）
+
+- **阻止 brand 侵蚀。** 将既有 brand 传播到缺口 2 列出的 `Map` 键类型和公开方法参数中：`Map<SessionId, Session>`、`Map<SessionId, Agent>`、`get(id: SessionId)`、`Map<CallId, …>`、ACP 的 `SessionId` surface、协调器的 `Map<SessionId, …>`。这是 diff 中机械量最大的部分，也是让*既有* brand 在查找处真正发挥作用（而不仅仅标注在结构体字段上）的关键。
+
+示意形状（工厂模式与已有的三个 brand 完全一致）：
+
+```ts ignore-check
+import type { Branded } from '@deepseek-ai/dsh-brand'
+
+/** A background bash task handle (generated `bash-N` by the local executor). */
+export type BashTaskId = Branded<'BashTaskId'>
+export function BashTaskId(id: string): BashTaskId {
+ return id as BashTaskId
+}
+
+/** A bash task's opaque isolation key — the consumer's owner identity, NOT the bash seam's. */
+export type OwnerToken = Branded<'OwnerToken'>
+export function OwnerToken(id: string): OwnerToken {
+ return id as OwnerToken
+}
+```
+
+## 曾考虑的替代方案
+
+### 为什么不把 `owner` 类型标注为 `SessionId`？
+
+显而易见的捷径是直接把 `owner` 类型标注为 `SessionId`——它确实*总是*一个会话 id。我们否决这个方案。bash 执行器 seam 是能力 seam（接口 `dsh-bash`、实现 `dsh-bash-local`、消费方 `dsh-tool-bash`），其 owner token 被*明确记录为刻意不透明*：执行器「从不解释它（seam 中没有访问策略——那是消费方的职责）」（`packages/bash/bash/src/types.ts`）。把 seam 字段类型标注为 `SessionId`，会把 `dsh-session` 的词汇引入一个不应知道 owner token *含义*的包——这会让通用执行后端耦合会话模型，并违背不透明 token 的设计。取代 `dsh-bash-local` 的沙箱或远程执行器不应继承会话依赖。独立的 `OwnerToken` brand 使 seam 保持解耦：`dsh-bash` 只知道「owner 是某种带 brand 的不透明 token」，而已经决定访问策略的 `dsh-tool-bash` 消费方，是把其 `SessionId` cast 为 `OwnerToken` 的唯一边界。该 brand 仍带来安全收益（不能把 `BashTaskId` 或裸 string 传到 owner 位置），且不引入耦合。
+
+## 不在范围内 / 可能的扩展
+
+遵循「不是每个 string 都需要 brand」的策略，刻意保持窄范围。以下每项都是合理的未来 brand 候选，附带推迟理由而非承诺：
+
+- **`ModelId`**（`GenerateOptions.model`，`LlmService` 适配器注册表的键）：一个真正的跨包查找键（config → agent → llm → 适配器）；合理的下一个 brand，仅为控制本 Agent Note 的影响范围而暂不纳入。
+- **`ToolName`**（`ToolRegistry` 的键）：由作者定义、人类可读，且很少与其他 id 混淆；最弱的候选，可能不值得加 brand。
+- **`ErrorCode`**（`HarnessError.code`）：一个封闭词汇（`ABORTED`、`NO_ADAPTER`……），不是逐实例的 id；如果要做，string 字面量联合类型比 brand 更合适。
+- **数值序号**：轮次号、步骤号和事件 `seq` 是 `number` 而非 `string`，`Branded<string>` 不适用；可以用并行的 `number & { readonly [BRAND]: B }` 变体来 brand 它们，但它们是位置序号、很少跨边界传递，收益较低。
+- **带校验的构造**：brand 工厂是纯 cast，无运行时检查，且每个边界（ACP `sessionId`、提供方签发的 `call.id`、`dsh-llm-deepseek` 中的空字符串回退）今天都信任裸 string。一个在边界处对格式错误的输入抛异常的 `SessionId.parse()` / `isValid()` 配套工具确实是缺口，但它是*运行时行为*变更，有自己的设计问题（什么算「格式错误」？失败时怎么办？），应在独立 Agent Note 中处理，不应捆绑进这次纯类型变更。
+
+## 验证
+
+已落地的不变式：`BashTaskId` 和 `OwnerToken` 定义在 `dsh-bash` 中，并端到端贯穿执行器 seam、`dsh-bash-local` 生成点与 `dsh-tool-bash` 面向模型的 surface，且 `dsh-bash` 未添加对 `dsh-session` 的依赖；没有任何以范围内 brand id（`CallId`/`SessionId`/`BashTaskId`）为键的集合使用裸 `string`；公开方法参数和导出签名保留 brand；每个原始 string 进入的边界（提供方 call id、ACP 会话 id、模型提供的 `task_id`）都通过 cast 工厂构造 brand，而不是散落的 `as` cast。
+
+## 后果
+
+- **两个接口面的机械性改动。** 传播 brand 涉及 bash seam（接口 + 实现 + 消费方）以及 ACP 会话 id 接口和持久化协调器。改动面广但严重度低：遗漏的位置是编译错误而非静默 bug。变更可观察地为纯类型变更——无快照或 e2e 行为差异。它与[统一 agent/会话标识决策](../simplification/2026-06-20-unify-agent-and-session-id.md)相邻，因为二者都触及会话 id / owner-token 边界；`OwnerToken` 出于上述解耦理由仍与统一后的 id 保持独立。
+- **Brand 不做校验。** Brand 是混淆防护，不是正确性证明：一个*错误的* 会话 id 只要仍是合法的 string，就和以前一样能通过类型检查器。本 Agent Note 不关闭这个缺口（见「不在范围内」）——它只阻止这类*类别*错误：传入错误*种类*的 id。
+- **「在哪里停下」仍是判断题。** 为 `BashTaskId` 加 brand 但不为 `ToolName` 加，为 `OwnerToken` 加但不为 `ModelId` 加，是对哪些 string「可能被混淆」的品味判断。合理的评审者可能想要更多或更少；`brand.ts` 中的策略是裁决依据，本 Agent Note 倾向于面向模型或用于访问控制的 id。

Each example carried a hand-rolled `start.ts` boot bootstrap, an infra preamble (`timer`, and — for the stdio demos — `logger` + `hmr`), nested includes of three shared YAML fragments (`base.yml` / `base-core.yml` / `acp-agent/acp-tail.yml`), and per-example `agent-loop`/persistence/system-prompt config.

+# Agent Note: 将示例应用提取为独立包
+
+Status: implemented
+
+[English](2026-06-20-extract-example-app-packages.md) | 中文
+
+## 问题
+
+示例目录本应是*精简的*——只包含演示的可变接线，而非演示的基础设施。在此次变更之前，它是臃肿的。每个示例都携带一份手写的 `start.ts` 启动引导、一段基础设施前导（`timer`，以及 stdio 演示所需的 `logger` + `hmr`（热模块替换））、三个共享 YAML 片段的嵌套引用（`base.yml` / `base-core.yml` / `acp-agent/acp-tail.yml`），还有各示例自身的 `agent-loop`/持久化/系统提示词配置。真正的应用——每个 agent（智能体）都需要的服务主干——散落在叶子配置和那些 include 中。
+
+叶子配置还拥有耦合的前门。ACP（Agent Client Protocol）要求 stdout 纯净，并通过 `session/new` 创建 agent；终端应用和 Headless 应用则预创建 `main`，但进程 I/O 契约不同。防止错误组合的唯一屏障是文档中的文字警告，而三个 `start.ts` 文件重复着 Loader 引导和生命周期代码。
+
+## 决策
+
+每个示例现在**主要是对一个应用包（package）的调用**，沿着既有的[接口 / 实现 / 消费方 seam](2026-06-13-capability-seams.md) 拆分接线：**应用包拥有组合**，叶子 `cordis.yml` 只拥有**可替换的选择**（哪个 LLM（大语言模型）适配器、哪个 bash 执行器、模型、提示词、持久化根目录）。
+
+- **`@deepseek-ai/dsh-agent-spine-demo`**（[packages/examples/agent-spine-demo](../../../../packages/examples/agent-spine-demo)）组合了不含提供方、不含执行器、不含 UI 的主干，并转发 agent loop（智能体循环）的 agent 列表配置。它对具体 loop 的依赖是有意为之，因为该包组合的是主干而非扩展主干；替换 loop 意味着提供另一个 bundle。
+- **`@deepseek-ai/dsh-tui-demo`**、**`@deepseek-ai/dsh-cli-demo`** 和 **`@deepseek-ai/dsh-acp-demo`** 各自内置其进程角色。TUI 包含全屏 UI 和预创建的 `main`；Headless 包含 one-shot driver 和预创建的 `main`；ACP 包含 bridge 且不预创建 agent。三者都包含 JSONL 持久化，并省略 stdout logger。
+- **`start.ts` 已移除。** 每个应用包都暴露一个 bin；`demo:*` 脚本调用它。Loader 引导、`.env` 加载和快速失败守卫位于共享的 [`@deepseek-ai/dsh-app-boot`](../../../../packages/ui/app-boot) 包（在逐文件覆盖率门禁下有单元测试——见[共享应用 bin 的启动胶水](../simplification/2026-07-04-share-app-bin-boot-glue.md)）；精简的自执行入口由 keyless 的 Loader 路径测试驱动。
+- **每个叶子 `cordis.yml` 精简为**后端、可选产品工具，以及一个承载应用配置的 app 条目。TUI 和 Headless 把模型/会话选择路由到预创建的 agent；ACP 把初始提供方/模型路由到 bridge。
+- **`base.yml`、`base-core.yml` 和 `acp-agent/acp-tail.yml` 已退役**——它们共享的主干现在位于 `dsh-agent-spine-demo` 中。
+
+`bash-local` 和 LLM 适配器仍然是**叶子选择**：bundle 提供 `tool-bash`（消费方 schema），叶子选择执行器实现，因此沙箱执行器或回放适配器无需触碰应用即可替换。
+
+### 实现修正：`hmr` 保留为叶子条目
+
+提案最初将 `hmr` 列入交互式应用内置的前门集群。对照代码验证后发现，将 `hmr` 内置到应用包中会在两个方面与 Cordis 冲突，因此改为作为**叶子 `cordis.yml` 条目**交付：
+
+1. `@cordisjs/plugin-hmr` 是一个仅限 Loader、仅限子进程的开发插件——它需要活跃的 `loader` 服务及其内部模块访问权限，因此只能在真实的 `demo:*`/bin 子进程中运行，不能在进程内的单元/覆盖率测试层运行。
+2. 进程内测试层（vitest）甚至无法*导入* vendor 的 `hmr` 模块（其 class-decorator `@Inject` 形式在 Vite 的 transform 下会失败），因此一个 `apply` 静态导入了它的包永远无法满足其主函数的逐文件 100% 覆盖率门禁。
+
+关键在于，`hmr` 不是 stdout 纯净隐患：ACP 配置中误加该条目不会破坏 JSON-RPC 帧。所有已交付应用都省略 stdout 控制台 logger；stdout 只归应用或协议 driver 所有。
+
+## 曾考虑的替代方案
+
+### 为什么不继续用共享 YAML include 来管理接线？
+
+旧的 `base*.yml`/`acp-tail.yml` include 已经去重了*配置*，但 YAML include 无法**封装**前门耦合——它只能在注释中描述，并信任每个叶子遵守。它也无法拥有 `bin`，因此启动胶水一直在三个 `start.ts` 文件中重复。包将「ACP 应用绝不向 stdout 输出日志」从文字警告变成了产物的属性：叶子中不存在可以写错的 logger 条目。
+
+## 验证
+
+- 示例目录只包含配置、README 和测试：`start.ts`、基础设施前导和共享 YAML include 已移除。
+- `demo:tui`、`demo:headless` 和 `demo:acp` 调用应用包的 bin。
+- 每个新包都有 README 和逐文件 100% 覆盖率；每个应用包还有一个 keyless 的真实 Loader 路径 bin 冒烟测试，用于捕获[事后分析 0001](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md) 中描述的导出形状故障。
+- ACP 回放套件通过应用包的 bin 启动，因此协议接线与组装后的后端行为都跨越真实的 Loader 边界。
+
+## 后果
+
+- **裸插件树的教学性。** 主干现在隐藏在 bundle 之后，查看完整树意味着打开 `dsh-agent-spine-demo`。应用包的 README 承担了这份教学职责。
+- **多了一层间接。**「这个演示加载了什么？」从扫描单个 YAML 变成了阅读一个包。
+
+## 相关
+
+- 取代[使共享示例基础配置与提供方无关](../../rejected/architecture/2026-06-20-providerless-example-base.md)：一旦主干移入 `dsh-agent-spine-demo` 且 `base*.yml` 文件被删除，将 `base.yml` 重命名为无提供方核心便不再有意义。
+- 基于[能力 seam](2026-06-13-capability-seams.md)的接口/实现/消费方拆分——后端和展示层保持为叶子选择；主干是共享 bundle。
+- 与[将包重组为模块化层级结构](2026-06-20-package-hierarchy.md)互补：新的 app/core 包按该层级结构归入既有分组（`core` 放可复用的主干 bundle，`ui` 放应用特有的前门）。
+- 后续的[冗余 agent 移除](../simplification/2026-07-20-remove-stdio-and-echo-agents.md)拥有最终的 TUI/Headless 拆分，并移除行式与仅 mock 的叶子。

Adding background subagents required the same lifecycle and interaction contract.

+# Agent Note: 后台任务运行时（`ctx.tasks`）与通用任务控制工具
+
+Status: implemented
+
+[English](2026-06-20-generic-long-running-tool-runtime.md) | 中文
+
+## 问题
+
+后台 bash 原本兼有两项职责：bash 执行器既运行进程，又管理 task id、所有权、增量读取、取消、完成监听器和面向模型的控制工具。新增后台 subagent 需要相同的生命周期与交互契约。如果每种长时间运行能力都独立实现该契约，就会重复隔离、清理、通知和提示词行为，还会让模型为每种生产方学习不同的收集与停止协议。
+
+任务注册表、控制工具与完成通知共同构成一项 harness 功能。bash 和 subagent 只提供执行专属的钩子，不拥有通用任务行为。
+
+## 决策
+
+`tasks/` 包组拥有后台任务语义：
+
+- `@deepseek-ai/dsh-tasks` 将运行中的工作注册为 `ctx.tasks`，并拥有 task id、授权、快照、读取、取消、等待、完成监听器与清理。
+- `@deepseek-ai/dsh-tool-tasks` 暴露 `task_output`、`task_list` 和 `task_kill`，注入完成通知，并提供后台任务的系统提示词指导。
+
+长时间运行工具是生产方。`dsh-tool-bash` 将 `BashProcess` 适配为增量输出与进程取消；`dsh-tool-subagent` 将子运行适配为最终输出与子运行释放。执行 seam 保持独立，不依赖会话或任务注册表。
+
+`TaskService` 是一个具体的进程内服务。TODO(task-service-backend)：当第二个后端明确所需生命周期后，将其公共契约与实现分离；systemd 驱动的运行时是一种可能方案，但本 PR（Pull Request）不臆测其持久性、重连、所有权或观察语义。
+
+## 运行时契约
+
+字面类型见[任务数据结构目录](../../../../docs/core-data-structures/tasks.md)。生产方调用 `ctx.tasks.start()`，传入 kind、label、可选的所属 `Agent`、可选的正数 `outputLimitBytes` 与一个 `run()` 函数。运行时会在调用 `run()` 前完成所有可能失败的预检工作，并且只调用一次。`run()` 返回钩子后，注册过程不会再执行可能失败的步骤而直接提交；生产方无法启动没有可收集 task id 的工作。
+
+`outputLimitBytes` 是生产方拥有的呈现策略，而非注册表缓冲区。注册表校验该值，并将其原样投影到 `TaskSnapshot`；通用控制接口添加自身的状态或通知元数据后，再将该上限应用于完整的面向模型输出。省略该值时保持现有接口行为，因此运行时不会向无关的生产方类别施加隐式默认值。
+
+面向模型的生产方会在规范成功值中暴露已提交的 id，通常为 `{ kind: 'background', taskId }`；Native 渲染仍可保留便于人类阅读的行文。预先被中止的后台调用会失败，而不是返回空操作，因为不存在可履行所承诺句柄的任务。一旦注册过程发布 id，取消就归任务自身的控制器与任务运行时所有：随后取消生产工具调用不得终止已发布的任务。`task_kill`、所有者资源释放和服务拆除会请求取消；前台执行仍与调用的 `exec.signal` 耦合。
+
+生产方钩子定义三项职责：
+
+- `cancel(reason?)` 同步请求终止，具备幂等性，并且必须使 `done` 完成。
+- `done` 从不拒绝，并且仅在生产方释放任务资源后完成。
+- 可选的 `readOutput()` 返回下一个消费式输出增量。省略该钩子即声明这是最终输出任务，其终止结果来自 `TaskOutcome.output`。
+
+状态包括 `running`、`stopping`、`completed`、`killed` 和 `failed`。退出码或停止原因等生产方专属信息放在 `detail` 中，注册表不解释这些信息。任务 kind 构成可合并扩展的字符串联合；task id 带品牌，并按 `<kind>-N` 生成，每个 kind 各有一个计数器。
+
+运行时为 `done` 附加一个 continuation，记录第一个终止结果、解决等待方，并逐个调用完成监听器，同时隔离每个监听器的错误。首次结果优先的结算在资源销毁期间至关重要：如果 `cancel` 抛出，运行时会强制将记录标为失败，并警告工作可能遗留，而不是永远等待一个可能永不完成的 promise。后续生产方结果不能覆盖该诊断，也不能重复通知。`cancel` 返回后如果最终未使 `done` 完成，仍会阻塞资源销毁，因为运行时无法区分这种情况与缓慢但有效的停止。
+
+任务注册不是生产方工具 fiber 的 effect。因此，重新加载工具或控制接口插件不会终止由 agent（智能体）和后端拥有的工作。任务服务自身释放时会取消所有实时任务，并等待遵守契约的生产方。
+
+## 授权与所有者生命周期
+
+task id 在运行时全局可见且可预测，因此注册表会授权每次访问。`get`、`read`、`wait` 和 `kill` 接受调用方 `Agent`；`list` 仅返回该调用方可见的任务。有所有者的任务仅允许对应的确切会话访问。无所有者任务向非 agent 调用方开放，并随任务服务一起终止。
+
+快照存储所有者的品牌化 `SessionId` 以供授权，生命周期操作则保留确切的实时 `Agent` 实例。这两种身份用途不同：会话相等性授予访问权，精确对象身份决定清理和完成通知的接收方。复用 agent 或会话 id，不能将旧作用域的清理或通知重定向到替代实例。
+
+某个所有者的第一个任务会向 `owner.ctx` 附加一个异步 effect。agent 作用域释放时会取消该所有者的实时任务、等待其终止记录，并移除其快照。该 effect 可跨生产方重载存续，并加入 agent 现有的完全停稳边界。任务服务保留 effect disposer，使服务重载可以在全局资源销毁后，从仍然存活的 agent 作用域中分离回调。
+
+对于遵守契约的生产方，`AgentHandle.dispose()` 只在所属后台工作停止后解决。需要比 agent 存活更久的工作必须以无所有者方式启动；要跨运行时重启存续，则需另行设计持久任务。
+
+## 服务接口
+
+`TaskService` 提供：
+
+- `start(spec)`：经过预检的原子注册。
+- `get(id, caller?)` 和 `list(caller?)`：非消费式快照。
+- `read(id, caller?)`：消费式流增量或幂等的最终结果。
+- `kill(id, caller?, reason?)`：取消。
+- `wait(id, timeoutMs, caller?, signal?)`：有界的终止等待。
+- `onTaskDone(listener)`：effect 作用域内的观察，具有精确所有者投递和监听器隔离。
+- `attachSurface(name)`：控制接口可用性防线。
+
+`wait` 在任务完成时返回终止快照，在等待超时时返回实时快照。中止一次等待只取消该次等待。如果结算已经将终止投递分配给该等待方，终止快照仍然优先。等待方在中止时同步注销，因此同一 tick 内的结算无法代表一个什么也未收到的读取方压制完成通知。
+
+如果生产方加载时没有任何控制接口，调用方就能启动无法收集或停止的工作。因此，`dsh-tool-tasks` 在其整个生命周期内调用 `attachSurface()`；没有附加接口时，`start()` 会在生产方开始执行前失败。该检查发生在启动时而非插件加载时，因为兄弟插件可能并发激活。自定义的非模型接口可以自行附加，无需让注册表了解工具名称。
+
+## 面向模型的控制接口
+
+`dsh-tool-tasks` 注册三个与 kind 无关的工具，并使用通用 UI 卡片：
+
+- `task_output(task_id, wait?, timeout_ms?)` 读取输出，并始终追加 `[status: ...]`。流式任务只返回上次读取以来的输出；最终输出任务在结算后返回结果。除非指定 `wait: true`，否则读取不会阻塞；等待超时由插件配置提供默认值并限定上限。等待超时会报告仍在运行的状态，不会停止任务。
+- `task_list()` 将调用方可见的任务返回为 `<id> [<kind>] <status> — <label>`，没有任务时返回 `(no background tasks)`。
+- `task_kill(task_id, reason?)` 立即请求取消。可选的已记录原因会转发给生产方。终止任务报告现有状态；生产方的取消操作若抛出，调用便会失败，任务保持运行。
+
+流式读取共享一个任务作用域内的消费游标，因为所属模型是预期读取方。UI 或多个独立读取方需要单独的非消费式观察 API；共享该游标会让读取方彼此消费对方的输出。
+
+系统提示词要求模型保留 task id、在后台工作运行时继续处理独立工作而非忙轮询或重复启动同一任务、在给出最终答案前收集相关任务，并终止不再重要的工作。完成时，系统会向确切所有者的会话注入一条已记录的 `context/message`；它会成为下一个请求的持久上下文，但不会唤醒空闲的 agent。
+
+当读取或等待交付终止任务、实时等待方在结算时认领了投递，或模型显式终止任务时，运行时将终止任务标为 `reported`。已报告的任务不会注入冗余的完成通知。监听器失败会独立记录，不会阻止后续监听器，也不会被等待方或资源销毁过程等待。当快照携带 `outputLimitBytes` 时，`dsh-tool-tasks` 会保持 UTF-8 边界，并复用生产方已有的截断标记，而不会重复添加。读取会为状态后缀预留空间并保留输出尾部；完成通知会先为稳定的 `background task <id>` 前缀与 `task_output` 指令预留空间，再截断可变的 kind、label、status、detail，乃至截断标记本身，因此 PTY 的最小上限仍能标识需要收集的任务。任务接口在策略有机会拒绝或短路分发之前，于最先执行的 pre-execute 监听器中解析调用方可见的生产方上限；随后通过任务定义最后一道的 `finalizeContent` 回调应用该上限，使规范化的工具错误、外层流水线失败与单文本策略结果都无法绕过该边界；经特意结构化的多块策略结果仍由策略拥有其形状与大小。
+
+## 生产方显式启用
+
+每个生产方通过带默认值的配置，自行决定其 schema 是否暴露 `run_in_background`。`dsh-tool-bash`、`dsh-tool-pty` 和每个 `dsh-tool-subagent` 实例都使用 `enableRunInBackground`，默认值为 true。禁用的实例会省略该参数；由于通用参数校验器允许未声明的键，它还会在执行时拒绝强制传入的后台参数。省略 schema 用于声明能力不可用；执行检查负责强制该约束。
+
+`ctx.tasks` 不改写生产方 schema。bundle 只转发其所拥有生产方的配置。如果后台调用在没有附加接口的情况下到达 `start()`，运行时防线会在执行前使其失败。
+
+## 生产方集成
+
+bash seam 暴露 `resolve`、`run` 和 `start`。`start(spec)` 返回一个 `BashProcess`，提供增量读取、取消、退出事实以及不拒绝的完全停稳 promise。本地执行器只为自身释放时能终止并等待进程而保留实时句柄。前台调用方继续直接使用 `resolve` 和 `run`。
+
+对于后台 bash，`dsh-tool-bash` 将调用方 agent 注册为所有者。其钩子将 `kill()` 映射为取消，将 `done` 映射为 completed 或 killed 的 `TaskOutcome`，并将 `readOutput()` 映射为进程的有界增量输出，以及溢出文件与沙箱通知。通用任务工具拥有 id、状态行、列表、等待和完成通知。
+
+对于后台 subagent，`dsh-tool-subagent` 创建由任务拥有的 `AbortController`，并在任务 starter 内启动提供方。无论提供方就绪前后，取消都会中止同一个 signal。`done` 同时等待子运行结果和子运行释放，将已完成输出映射为最终结果，将中止映射为 `killed`，并将其他停止原因或基础设施失败映射为 `failed`。中间子历史保留在子会话中，不通过 `readOutput()` 暴露。
+
+## 备选方案
+
+### 按功能划分控制工具
+
+为 bash 与 subagent 分别提供输出/停止工具，会重复 id、隔离、清理、通知和指导，并增加模型的 schema 与协议负担。统一运行时将执行专属行为保留在生产方中，而无需复制任务生命周期。
+
+### 立即抽象任务运行时后端
+
+当前 `TaskStart.run()` 契约传入进程内回调与确切的 `Agent` 对象。持久化后端会改变身份、重启、所有权与观察语义，因此在第二种实现出现前抽取接口，会固化错误的边界。
+
+### 由消费方负责授权或清理事件
+
+由消费方负责检查，会使每个新接口的隔离实现不一致或遗漏。广播清理事件会迫使每个监听器过滤所有 agent，且不提供注册 disposer。集中授权加一个所有者作用域内的 effect，为每个消费方提供相同防线，以及可等待、可移除的生命周期钩子。
+
+### 阻塞输出或单独的等待工具
+
+默认阻塞会在后台工作运行时串行化父任务。只等待而不读取会增加一次不返回有用信息的模型调用和 schema。`task_output(wait: true)` 显式表达阻塞，并将其与结果交付合并。
+
+等待使用共享的 deadline 原语，而不使用通用工具超时策略。等待超时是一次成功的观察，会返回 `[status: running]`；通用策略会将它替换为超时错误。任务返回 task id 后，没有任何工具调用超时会控制任务生命周期。
+
+### 由运行时拥有输出接收端
+
+推送式接收端可以集中缓冲，但 bash 已经在执行器 seam 后拥有有界缓冲、截断与溢出文件。拉取格式化增量能够保留这一所有权。拥有存储的持久化后端可能足以支持重新审视生产方接口。
+
+### 随机 id、提升或生命周期会话事件
+
+授权而非不可猜测性才是访问边界，并且 id 不用于派生文件系统路径；顺序生成的品牌化 id 可保持 transcript（文本记录）易读。将前台任务提升为后台任务需要 SDK 并未规定的用户交互契约。启动、读取和通知已作为工具与上下文事件记录，因此专用任务会话事件会重复面向模型的事实。
+

+# Agent Note: 将包重组为模块化层级结构
+
+Status: implemented
+
+[English](2026-06-20-package-hierarchy.md) | 中文
+
+[冗余 agent 移除](../simplification/2026-07-20-remove-stdio-and-echo-agents.md)直接删除最初的 `support/ui-stdio` 接口，而不是将其迁移；[仅面向自动化的 ACP 决策](../simplification/2026-07-23-acp-automation-only-protocol.md)把 ACP 放在 `packages/acp/acp` 下，而不是面向人类的 UI 组。这里拥有的决策仍是统一的二层目录深度。
+
+## 问题
+
+`packages/` 原先是扁平的：18 个包（package）全部位于 `packages/<name>/`，从路径上完全看不出一个包属于核心产品 API、可替换的能力 seam、提供方适配器、产品集成，还是示例/测试支撑。包的 README 带着 `FIXME(package-hierarchy)`，`scripts/publint-all.ts` 带着 `TODO(package-inventory)`，标记的正是这个问题。核心包、提供方集成、能力 seam、示例 UI 支撑和仅用于快照的回放支撑看起来同样基础。
+
+这不仅仅是外观问题。由于每个顶层包看起来都属于同一个公开接口，未来移除更加困难，而 publish/lint/doc 脚本不得不通过注释或手工维护的静态列表来编码意图，而不是从布局中直接读取。
+
+## 决策
+
+按模块角色将包分组，统一放在 `packages/<group>/<pkg>/` 深度。分组目录是纯容器（没有 `package.json`）；每个包保留其 `@deepseek-ai/dsh-<pkg>` 名称——这是仓库结构与维护策略的调整，不是包的重命名。

+
+### 放置决策
+
+- **能力族使用同名嵌套。** 一个族的接口包位于 `packages/<group>/<group>/`（`llm/llm`、`bash/bash`、`session-persistence/session-persistence`），实现和消费方作为扁平兄弟并列。不设额外的 `adapters/`/`impls/` 子层——每个包恰好在深度 2，这使 workspace glob 保持简洁的 `packages/*/*`，并让一条 `@deepseek-ai/dsh-*` tsconfig 通配符即可解析所有包（唯一的目录名使 first-on-disk-wins 无歧义）。
+- **`session` 留在 `core/`；持久化独立成族。** 会话日志是核心产品 API。其存储后端构成一个平行的能力族（`session-persistence/`），与 `llm/` 和 `bash/` 对称，而非嵌套在 `core/session/` 下。
+- **`agent-loop` 在 `core/` 中。** 它是 `agent` seam 唯一的具体实现，但作为 harness 的默认产品循环交付，因此与核心主干同处。插件仍然依赖 `agent` 的词汇，从不依赖 `agent-loop`，所以循环仍可替换。
+- **产品自动化与面向人类的 UI 是两个独立分组。** `acp` 是位于 `acp/` 下的产品传输层，而命令、审批、交互和展示适配器位于 `ui/` 下。仅开发用的 invariants 与回放基础设施仍留在 `support/` 中。
+
+### 去重包列表
+
+包列表此前在五个地方重复枚举。统一的深度 2 布局使大部分可以被推导：
+
+- `tsconfig.base.json` 通过一条 `@deepseek-ai/dsh-*` `paths` 通配符（每个分组列一个候选）映射所有包，取代了逐包条目。聚合配置（`tsconfig.host.json`、`tsconfig.client.json`）复用该源映射，并携带显式 project references 以保持包/vendor 类型检查边界完整。（这里引入了一个细节：路径候选中包含 `/*/`，朴素的正则注释剥离器会将其误认为块注释——`scripts/doc-typecheck.ts` 正是因此通过 TypeScript 解析器读取 JSONC 配置，而非手动剥离注释。）
+- `scripts/publint-all.ts` 通过读取层级结构（`packages/<group>/<pkg>`）推导列表，解决了 `TODO(package-inventory)`。
+- 聚合配置的 project `references` 仍为显式列表——TypeScript project references 没有通配符形式。从 manifest（元数据清单）生成这些引用留作后续工作（见[通过发现机制获取包清单](../../proposed/process/2026-06-20-discover-package-inventory.md)）。
+
+### 新增的护栏
+
+两道 doc-sync/hygiene 门禁确保结构及其引用保持正确，使本次重组所需的手动检查无需日后重复：
+
+- `scripts/verify-package-paths.ts` 标记 Markdown 或 `.ts` 注释/字符串中的 `packages/<path>` 引用，如果该引用无法解析**且**某个路径段命名了一个真实存在的包，即指向已移动包的陈旧路径。如果路径命名的包在任何地方都不存在（前瞻性提案），则不予标记，因此该门禁在 proposed/implemented/rejected 中统一适用。
+- `scripts/check-workspace-constraints.ts` 断言 `packages/<group>/<pkg>` 形状：分组目录不带 `package.json`，且没有包扁平地位于根层或嵌套更深。分组名称保持开放——添加新分组无需修改门禁；只有深度 2 的形状是固定的。
+
+## 曾考虑的替代方案
+
+- **第三层（每个族下设 `adapters/`/`impls/`）**：否决。统一深度 2 使 workspace glob 保持简洁的 `packages/*/*`，并让一条 `@deepseek-ai/dsh-*` tsconfig 通配符即可解析所有包。
+- **将持久化嵌套在 `core/session/` 下**：否决。存储后端构成一个平行的能力族，与 `llm/` 和 `bash/` 对称，而会话日志本身属于核心产品 API。
+- **`ui-stdio` 放在 `ui/` 下**：否决。它曾是与示例耦合的开发支撑，不是产品接口。
+
+## 后果
+
+本次重组在一次协调的变更中搅动了 import、workspace glob、文档链接、构建引用和包路径。这种变动在发布前是可接受的（依据 AGENTS.md 中「基础优先于爆炸半径」的立场），因为它阻止了扁平布局将支撑包固化为产品契约，且这是一次性成本：通配符 `paths`、glob 推导的 publint 列表和形状门禁意味着新增一个包无需额外的结构性编辑。

## Problem
LLM provider requests should identify the product making them. That is useful for provider-side support, abuse investigation, compatibility debugging, and traffic analytics. Before this Agent Note the harness only partially did this: the hand-rolled DeepSeek adapter sent a hand-copied `User-Agent` constant (`packages/llm/llm-deepseek/src/adapter.ts`), while the pi-ai-backed twin sent no harness-owned headers at all (`packages/llm/llm-pi-ai/src/adapter.ts`). New adapters could therefore omit attribution silently, and a library-backed adapter could drift from the hand-rolled adapter even though [the twin-adapter Agent Note](2026-06-13-twin-llm-adapters.md) exists to keep the provider seam honest across both implementations.

+# Agent Note: 对提供方请求强制携带 `User-Agent` 归属标识
+
+Status: implemented
+
+[English](2026-06-21-mandatory-app-attribution-headers.md) | 中文
+
+## 问题
+
+LLM（大语言模型）提供方请求应当标识发出请求的产品。这对提供方侧的技术支持、滥用调查、兼容性调试和流量分析都有价值。在本 Agent Note 之前，harness 只做了部分工作：手写的 DeepSeek 适配器发送了一个手动复制的 `User-Agent` 常量（`packages/llm/llm-deepseek/src/adapter.ts`），而基于 pi-ai 的孪生适配器则完全不发送 harness 自有的头部（`packages/llm/llm-pi-ai/src/adapter.ts`）。因此新适配器可以悄无声息地省略归属标识，而基于库的适配器也可能与手写适配器产生偏差——尽管[孪生适配器 Agent Note](2026-06-13-twin-llm-adapters.md) 的存在正是为了让两种实现在提供方 seam 上保持诚实。
+
+直接触发因素来自 OpenRouter 的[应用归属](https://openrouter.ai/docs/app-attribution)文档。OpenRouter 根据 `HTTP-Referer` 加上 display/category 头部来创建应用页面和排名。这有价值，但它不是 HTTP 标准中的应用身份机制。风险在于：把 OpenRouter 的精确头部集当作通用标准来采纳，然后将提供方特有的头部泄漏到直连 DeepSeek 的请求、未来的 OpenAI/Anthropic/Vertex 适配器、测试服务器或无限期记录未知字段的代理中。
+
+## 调研
+
+- **OpenRouter 的机制是提供方特有的。** 其当前文档说明应用归属通过 `HTTP-Referer`（必需）、`X-OpenRouter-Title` 和 `X-OpenRouter-Categories` 来追踪；`X-Title` 仅为向后兼容而接受。其 API 参考称这些头部为可选，并说它们使应用在 OpenRouter 上可被发现。这是一份具体的 OpenRouter 契约，而非 IETF 或 OpenAI 兼容 API 标准。
+- **在 agent 工具生态中，`HTTP-Referer` 是一种 OpenRouter 感知的约定，而非通用 agent 约定。** 它足够常见，以至于 OpenRouter SDK 和示例直接暴露它，面向 OpenRouter 的框架通常需要一种方式来透传它。但 ACP（Agent Client Protocol）等 agent 协议在自己的 initialize 消息中协商名称、版本和能力，而模型提供方请求仍需 HTTP 层面的身份标识。因此「在 agent 世界中被接受」意味着「被 OpenRouter 集成所识别」，而非「可跨 agent 运行时或提供方移植」。
+- **编程 agent 在 `User-Agent` 中标识产品和版本。** 公开实现在环境细节和提供方特有的附加头部上各有不同，但产品身份是共同契约；不存在通用的精确格式。
+- **标准化的通用客户端身份头部是 `User-Agent`。** RFC 9110 第 10.1.5 节将 `User-Agent` 定义为用户代理软件身份，说明它用于互操作性报告和分析，并说用户代理应当在每个请求中发送它（除非被配置为不发送）。这是唯一直接对应「哪个产品在发出此 HTTP 请求」的标准头部。
+- **`Referer` 是标准的，但 OpenRouter 的 `HTTP-Referer` 不是标准字段。** RFC 9110 第 10.1.3 节将 `Referer` 定义为获取目标 URI 的来源 URI，并用大量篇幅讨论隐私限制。OpenRouter 则要求 `HTTP-Referer`，将其用作应用 URL 标识符。该名称和含义是 OpenRouter 特有的，尽管它形似标准 `Referer` 头部的 CGI 环境变量形式。
+- **`From` 是标准的，但不适合作为强制默认值。** RFC 9110 第 10.1.2 节将 `From` 定义为负责用户代理的人的电子邮件地址。机器人代理应当发送它以便服务器联系运营者，但非机器人代理出于隐私和安全策略考虑不应在未经用户显式配置的情况下发送。harness 可以后续支持运营者联系方式，但不得凭空捏造或全局强制要求。
+- **请求体中的 `user` 或 `metadata` 字段不是应用归属。** 部分模型 API 暴露稳定的终端用户标识符、请求元数据、标签或项目/账户头部。这些对滥用监控、内部计费、仪表盘或链路追踪有用，但它们要么标识的是终端用户而非产品，要么是提供方特有的 body schema，要么不保证能通过 OpenAI 兼容网关透传。它们不能替代静态的应用身份头部。
+- **SDK 遥测头部标识的是 SDK，而非应用。** 官方和第三方 SDK 常发送库/版本头部。这些帮助 SDK 维护者调试其客户端，但除非应用显式提供产品归属层，否则它们不能标识 harness 作为应用。
+- **pi-ai 有一流的头部钩子。** `@earendil-works/pi-ai` 的 `StreamOptions.headers` 将调用方头部最后合并（覆盖提供方默认值），因此基于库的适配器无需包装或上游改动即可满足与手写适配器相同的协议格式契约。mock 服务器测试套件对两个适配器都断言头部到达了线路。
+
+## 决策
+
+在 LLM 适配器边界，提供方请求归属是强制的，且仅使用标准 `User-Agent` 头部。规则：每个生产 LLM 适配器在每个提供方 HTTP 请求上发送一个静态、非机密的应用身份，且每个适配器都有测试证明 `User-Agent` 到达了线路（mock 服务器断言收到的头部；对于基于库的适配器，通过库的头部钩子馈入同一个 mock 服务器断言）。
+
+本 Agent Note **不**实现 OpenRouter 应用归属。`HTTP-Referer`、`X-OpenRouter-Title`、`X-Title` 和 `X-OpenRouter-Categories` 是 OpenRouter 特有的产品展示头部，不是提供方无关的模型请求归属。它们可以后续由 OpenRouter 适配器或显式 OpenRouter 模式提出，附带自己的隐私/产品决策、测试和文档。在此之前，即使请求指向 OpenRouter，也只发送本 Agent Note 定义的共享 `User-Agent` 归属。
+
+提供方无关的身份由 `dsh-llm`（`packages/llm/llm/src/attribution.ts`）拥有，而非各适配器。`AppIdentity` 仅包含构建 `User-Agent` 所需的公开产品事实，默认的 `APP_IDENTITY` 确定了提案中留待决定的值：
+
+- `User-Agent` 的产品 token：`deepseek-harness`（与 Agent Note 之前的线路值及仓库/组织身份保持连续性）
+- 版本：通过 `createRequire` 从所属包的 manifest 读取，绝不手动复制常量
+- 应用 URL：`https://github.com/deepseek-ai/deepseek-harness-sdk`——计划中的公开主页；`attribution.ts` 中的 `FIXME` 标记在该仓库实际存在之前阻塞发布
+
+默认值是强制的且非空。白标部署通过向 `attributionHeaders(identity)` 传入自己的 `AppIdentity` 来覆盖——覆盖 seam 就是函数参数，在有消费方需要之前不做部署配置管道——省略时回退到 harness 默认值而非抑制归属。没有逐请求 API 允许模型、用户提示词、会话 id、cwd、用户邮箱、API key 所有者或本地机器身份影响这些字段。
+
+线路映射（`attributionHeaders`；代码中头部名称小写——HTTP 字段名在线路上不区分大小写）：
+
+| 目标 | 映射 |
+|---|---|
+| 所有基于 HTTP 的适配器 | `User-Agent: {product}/{version} (+{url})`——括号中的 `+url` 注释符合 RFC 9110 保守的 product/comment 语法。 |
+| 直连 DeepSeek 端点 | `User-Agent`；除非 DeepSeek 文档化了等效契约，否则不发送 OpenRouter 特有头部。 |
+| OpenRouter 端点 | 目前仅 `User-Agent`。本 Agent Note 下不发送 `HTTP-Referer`、`X-OpenRouter-Title`、`X-Title` 或 `X-OpenRouter-Categories`。 |
+| 未来提供方 | 仅 `User-Agent`，除非后续提供方特有的 Agent Note 接受额外头部。不要类比复用 `HTTP-Referer`。 |
+
+端点检测不在本 Agent Note 范围内，因为此处不接受任何端点特有的映射。如果后续支持 OpenRouter，检测必须是显式的：要么是专门的 OpenRouter 提供方包，要么是显式的 `provider: 'openrouter'` / `attributionTarget: 'openrouter'` 配置，而非任意路径片段或模型名称。
+
+## 验证
+
+已落地的契约：
+
+- `dsh-llm` 为 `LlmAdapter` 作者文档化了强制的 `User-Agent` 归属契约（`LlmAdapter` JSDoc、包 README，以及 `docs/core-data-structures/llm-streaming.md` 的适配器契约章节）。
+- 共享辅助函数（`attributionHeaders` / `userAgent`）从包元数据构建应用身份和标准 `User-Agent` 值，适配器无需手动复制版本常量。
+- `dsh-llm-deepseek` 在每个请求上发送共享的 `User-Agent`，其 mock 服务器套件断言精确值。
+- `dsh-llm-pi-ai` 通过 pi-ai 的 `StreamOptions.headers` 钩子发送相同的 `User-Agent`，其 mock 服务器套件断言精确值。
+- 本 Agent Note 下没有适配器发送 OpenRouter 特有的归属头部（`HTTP-Referer`、`X-OpenRouter-Title`、`X-Title`、`X-OpenRouter-Categories`）。
+- 没有应用归属字段携带机密、本地路径、会话 id、提示词文本、模型输出、用户邮箱或逐用户的稳定标识符。
+- 适配器 README 声明了 `User-Agent` 归属策略，并明确避免将 OpenRouter 应用归属记录为已实现的行为。
+
+## 曾考虑的替代方案
+
+**现在就实现 OpenRouter 应用归属。** 本 Agent Note 否决。发送 `HTTP-Referer` 加 `X-OpenRouter-Title` 可以满足 OpenRouter 排名，但这些头部是提供方特有的产品功能，不是本 Agent Note 试图标准化的提供方无关的模型请求归属。支持它们应当是后续显式的 OpenRouter 适配器/模式决策，而非隐藏在首个共享归属辅助函数中。
+
+**向所有提供方发送 OpenRouter 头部。** 否决。这会把一份自定义的 OpenRouter 契约当作通用标准，并向未要求这些字段的提供方发送语义误导的头部。还有风险将 `HTTP-Referer` 当作通用应用 URL 字段使用，尽管标准 HTTP 已有 `User-Agent` 用于产品身份、`Referer` 用于不同的浏览上下文概念。
+
+**仅使用提供方账户/项目身份。** 否决。组织/项目头部、API key、云账户和计费项目标识的是谁付费或谁拥有请求，而非哪个应用在发送流量。它们也不暴露公开的应用标题/类别，无法帮助 OpenRouter 等网关构建应用排名。
+
+**终端用户 `user`/`metadata` 字段。** 本 Agent Note 否决。这些对滥用监控和客户支持有价值，但描述的是请求背后的人或租户。应用归属必须是静态的产品身份，且可安全地在每个请求上发送。
+
+**仅配置启用的归属。** 否决。默认关闭的设置正是适配器不断漂移的原因。策略是强制默认归属加可覆盖的公开值，而非可选归属。
+
+**以产品命名的 token（`deepseek-harness-sdk`）。** 曾考虑用于 `User-Agent` token，因为产品名是 DeepSeek Harness SDK。`deepseek-harness` 因连续性胜出：它是提供方从本代码库已经看到的身份，与组织/仓库身份和包 scope 一致，且在展示文案承载产品名的同时保持线路归属稳定。
+
+## 后果
+
+**提供方看到流量来自 harness。** 这正是目的，但意味着此前混在通用 SDK 流量中的部署变得可识别。缓解措施：仅发送静态公开产品数据，并允许 fork/白标部署传入自己的 `AppIdentity`。
+
+**应用 URL 指向一个尚不存在的仓库。** `deepseek-ai/deepseek-harness-sdk` 是计划中的公开主页；在它创建之前，该 URL 是一个悬空承诺。常量上的 `FIXME` 标记阻塞发布，不允许带着未解决的问题出门（见 `docs/development.md` 标记语义）。
+
+**不同客户端库的头部支持有差异。** 手写适配器直接设置头部；基于 pi-ai 的适配器依赖 pi-ai 继续尊重 `StreamOptions.headers`（最后合并覆盖提供方默认值）。线路级 mock 服务器测试是守卫：如果 pi-ai 升级后不再投递该头部，套件会变红。这对抽象施加了有益的压力：一个无法设置强制头部的提供方适配器不能完整实现 harness 的 LLM 契约。
+
+**OpenRouter 排名尚未受益。** `User-Agent` 是提供方无关的 HTTP 身份的正确基线，但它不会创建 OpenRouter 应用页面或排名，因为 OpenRouter 要求 `HTTP-Referer` 来实现该产品功能。这是有意为之：公开应用市场参与是一个独立的产品决策，不是强制请求归属的前提。

## Problem
The harness needs model-facing web tools without binding the model contract to one vendor's API shape. Search is the immediate pressure point: supporting both Exa search and Perplexity search from the start — two deliberately different provider shapes (Exa returns a flat `results[]` of `{title, url, highlights, publishedDate}`; Perplexity returns a generated answer plus citations) — is what proves the normalized seam does not just mirror one vendor. Fetch is a separate capability: an anonymous public HTTP(S) fetch backend has transport, security, redirect, decoding, and size-limit concerns that are not the same as provider-backed search.

+# Agent Note: Web 能力 seam——稳定的工具覆盖多个提供方
+
+Status: implemented
+
+[English](2026-06-24-web-capability-seam.md) | 中文
+
+## 问题
+
+harness 需要面向模型的 web 工具，但不能将模型契约绑定到某一家厂商的 API 形状上。搜索是当前的压力点：从一开始就同时支持 Exa 搜索和 Perplexity 搜索——两种刻意不同的提供方形状（Exa 返回扁平的 `results[]`，每项包含 `{title, url, highlights, publishedDate}`；Perplexity 返回一段生成式回答加引用列表）——正是用来证明归一化的 seam 并非只是镜像某一家厂商。Fetch 是另一项独立能力：匿名公开 HTTP(S) fetch 后端涉及传输、安全、重定向、解码和大小限制等关注点，与提供方支撑的搜索并不相同。
+
+面向模型的接口必须保持稳定，而后端可以更换。更换搜索提供方不应改变模型发起查询的方式；更换 fetch 实现不应改变模型请求 URL 的方式。反过来，提供方包也不应仅仅因为自己有额外的提供方特有旋钮就暴露自己的面向模型工具 schema。
+
+如果把搜索和 fetch 直接放进 `dsh-tool-web`，面向模型的工具就要同时承担提供方选择、后端请求映射、传输策略、结果归一化、提示词引导、展示和 schema 注册。让每个提供方注册自己的工具则有相反的问题：工具的可用性、名称、描述和参数将取决于恰好加载了哪些提供方包，提供方特有字段会泄漏到模型契约中。
+
+还有一个提供方选择的问题。现有的 `tool-bash` 和 `tool-fs` 可以依赖 Cordis 的 `inject`，因为只有一个后端服务键。Web 有两项独立能力（`search` 和 `fetch`），每项能力可能有多个提供方。`inject: ['web']` 能证明 seam 存在，但不能证明存在可用的搜索或 fetch 提供方，也无法定义多个提供方注册时谁胜出。
+
+## 决策
+
+Web 访问是一个一等能力 seam，遵循[能力 seam Agent Note](2026-06-13-capability-seams.md)：
+
+1. `@deepseek-ai/dsh-web`（`packages/web/web`）拥有 `ctx.web`、提供方注册、提供方选择、共享的请求/结果词汇，以及 web 特有的错误。
+2. 提供方包实现具体后端并向 `ctx.web` 注册能力，例如 `@deepseek-ai/dsh-web-search-exa`、`@deepseek-ai/dsh-web-search-perplexity`、`@deepseek-ai/dsh-web-search-deepseek` 和 `@deepseek-ai/dsh-web-fetch-local`。
+3. `@deepseek-ai/dsh-tool-web`（`packages/web/tool-web`）拥有面向模型的 `web_search` 和 `web_fetch` 工具 schema、提示词段落、参数校验、结果格式化，以及通过 `ctx.web` 实现的工具展示。
+
+提供方不注册工具。提供方注册能力。`dsh-tool-web` 是面向模型的名称、描述、提示词引导、JSON Schema、展示的唯一所有者。
+
+搜索和 fetch 是两个独立工具，但属于同一个 web 访问 seam。`ctx.web` 为两个并行注册表统一拥有提供方选择、abort/错误词汇和部署配置。它们的请求 schema 和提供方逻辑保持独立；共享的服务是触达 web 的产品边界。
+
+`dsh-tool-web` 在产品启用了相应工具且 `ctx.web` seam 存在时注册面向模型的 web 工具。后端可用性是执行时关注点，而非 schema 注册时关注点：
+
+- `web_search` 在产品/应用启用了 web 搜索时注册，`web_fetch` 在启用了 web fetch 时注册。
+- 工具绝不会仅仅因为其选定的提供方缺失、配置错误、缺少凭证、存在歧义或暂时不可用就被注销。
+- 提供方在执行时解析，当选定的能力无法运行时返回结构化的 `WebError`。
+
+这使模型 schema 保持稳定，而不将插件加载顺序、凭证状态或 HMR（热模块替换）时序纳入面向模型的契约。如果 web 搜索已启用但不存在可用的搜索提供方，`web_search` 仍然可见，执行时以结构化的 `WebError`（如 `WEB_PROVIDER_UNAVAILABLE` 或 `WEB_PROVIDER_CONFIGURED_UNAVAILABLE`）失败。如果某个提供方在 `dsh-tool-web` 之后出现，下一次执行即可使用它而无需更改 schema。如果某个提供方在调用过程中消失，执行以结构化的 `WebError` 失败，而不是静默选择另一个提供方或回退到 `UNKNOWN_TOOL`。
+
+该 seam 刻意不暴露任何观察面——没有注册表变更事件，也没有聚合的能力状态查询。不可用性是调用方通过执行观察到的事实：`search()`/`fetch()` 在调用时解析提供方，并抛出命名了失败原因的结构化 `WebError`。[观察面 Agent Note](../simplification/2026-07-04-drop-unconsumed-web-observation-surface.md) 记录了这一判断：基于调用的派生选择与基于启用的注册使得没有消费方需要变更信号或独立于执行和错误路由的可用性探测；未来的提供方状态面板会重新引入它实际消费的最小信号或查询。
+
+## 包拓扑
+
+由三个包构成的接口/实现/消费方拆分沿用 bash 和 filesystem 的模式，但*接口*包更接近 LLM（大语言模型） seam。`LlmService`（`packages/llm/llm/src/index.ts`）是一个按名称键控的提供方注册表：`registerAdapter(models, adapter)` 将适配器存入 `Map`、返回 disposer、对重复键抛出 `DUPLICATE_ADAPTER`、在解析时抛出 `NO_ADAPTER`。`ctx.web` 沿用该注册表形状，但有两种能力类别和更丰富的选择策略（配置的提供方 id，或在恰好只有一个可用提供方注册时自动选择），因此执行时抛出的 `WebError` 能解释搜索或 fetch 能力为何无法运行。
+
+依赖方向与 bash 和 filesystem 一致：
+
+```text
+@deepseek-ai/dsh-tool-web --depends on--> @deepseek-ai/dsh-web <--depends on-- @deepseek-ai/dsh-web-search-exa
+ consumer interface implementation
+ <--depends on-- @deepseek-ai/dsh-web-search-perplexity
+ implementation
+ <--depends on-- @deepseek-ai/dsh-web-search-deepseek
+ implementation
+ <--depends on-- @deepseek-ai/dsh-web-fetch-local
+ implementation
+```
+
+运行时，提供方包向 `ctx.web` 注册能力；`tool-web` 向 `ctx.tools` 注册稳定的工具并通过 seam 执行：
+
+```mermaid
+flowchart LR
+ exa["@deepseek-ai/dsh-web-search-exa"] -->|registerSearchProvider| web["@deepseek-ai/dsh-web / ctx.web"]
+ perplexity["@deepseek-ai/dsh-web-search-perplexity"] -->|registerSearchProvider| web
+ deepseek["@deepseek-ai/dsh-web-search-deepseek"] -->|registerSearchProvider| web
+ fetchLocal["@deepseek-ai/dsh-web-fetch-local"] -->|registerFetchProvider| web

+ toolWeb -->|ctx.tools.register| webSearch["tool: web_search"]
+ toolWeb -->|ctx.tools.register| webFetch["tool: web_fetch"]
+```
+
+`@deepseek-ai/dsh-web` 仅依赖 Cordis 和底层 harness 支持。它声明 `ctx.web`、提供方接口、请求/结果类型、提供方可用性契约和错误码。它不导入工具、agent、会话、LLM 或提供方包。
+
+提供方包仅依赖 `dsh-web` 和 Cordis。它们拥有凭证、端点、协议格式映射、解析和 `WebError` 转换，使用平台 `fetch`。每个提供方注入共享服务并注册后端；只有 `dsh-web` 拥有 `ctx.web` 键。提供方私有的协议形状不会产生对 `ctx.llm` 或 Cordis HTTP 服务的依赖。
+
+`@deepseek-ai/dsh-tool-web` 依赖 `@deepseek-ai/dsh-web`、`@deepseek-ai/dsh-tools`、`@deepseek-ai/dsh-system-prompt` 和 Cordis。它从不导入具体的提供方包。
+
+## `ctx.web` 契约
+
+`ctx.web` 是一个提供方注册表加上一个带提供方选择的执行面。注册表部分与 `LlmService` 保持接近：每种能力类别一个 `Map<id, provider>`，`registerSearchProvider`/`registerFetchProvider` 方法返回 disposer，重复 id 抛出 `WebError`，执行时解析在选定提供方缺失或不可用时抛出异常。权威签名见 `packages/web/web/src/types.ts`；seam 的形状：
+
+```ts
+import type { WebFetchRequest, WebFetchResult, WebSearchRequest, WebSearchResult } from '@deepseek-ai/dsh-web'
+
+interface WebSearchProvider {
+ readonly id: string
+ available(): boolean
+ search(request: WebSearchRequest, signal?: AbortSignal): Promise<WebSearchResult>
+}
+
+interface WebFetchProvider {
+ readonly id: string
+ available(): boolean
+ fetch(request: WebFetchRequest, signal?: AbortSignal): Promise<WebFetchResult>
+}
+
+interface WebService {
+ registerSearchProvider(provider: WebSearchProvider): () => void
+ registerFetchProvider(provider: WebFetchProvider): () => void
+
+ search(request: WebSearchRequest, signal?: AbortSignal): Promise<WebSearchResult>
+ fetch(request: WebFetchRequest, signal?: AbortSignal): Promise<WebFetchResult>
+}
+```
+
+可选的 signal 是执行控制，而非业务输入：`tool-web` 直接传递 `exec.signal`，使轮次取消、工具超时和 agent dispose（资源释放）能到达提供方的网络请求、流读取器和高开销解码。seam 不传递 `ToolExecution`——否则 `dsh-web` 就要依赖 `dsh-tools`。
+
+提供方 id 是稳定字符串，在各自的能力类别内唯一。注册重复的搜索提供方 id 或重复的 fetch 提供方 id 会失败，而非静默替换旧提供方。提供方注册返回 disposer，沿用现有的 `ctx.tools.register()`/`ctx.systemPrompt.section()` 模式：变更包裹在 `ctx.effect()` 中，注册随贡献它的 fiber 一起拆除。
+
+## 提供方可用性与选择
+
+提供方可用性与能力选择是两个独立概念，但都保持最小化。提供方仅报告该具体实现是否可用，通过廉价的本地检查（如凭证是否存在、端点配置是否可解析）。提供方的 `available()` 禁止发起网络调用。
+
+`LlmService` 完全没有状态类型：可用性通过注册表成员资格加解析时抛出来表达。`ctx.web` 遵循同样的纪律。seam 不暴露聚合的能力状态查询——`search()`/`fetch()` 在每次调用时根据配置的提供方 id、已注册的提供方和每个提供方廉价的本地 `available()` 布尔值派生选择结果，选择失败就是执行时抛出的结构化 `WebError`。需要知道某项能力能否运行的调用方通过执行并路由该错误来获知；没有任何东西作为可变服务状态存储。
+
+该布尔值是选择的输入，而非健康系统。`tool-web` 从不直接调用提供方的 `available()`——它进入 seam 的唯一路径是 `search()`/`fetch()`——因此选择策略只有一个所有者。
+
+选择不得依赖注册顺序。Cordis 加载顺序、配置排列和 HMR 时序不是产品语义。
+
+| 情况 | 执行行为 |
+|---|---|
+| 配置的提供方 id 已注册且 `available() === true` | 运行该提供方 |
+| 配置的提供方 id 未注册 | 以 `WEB_PROVIDER_CONFIGURED_MISSING` 失败 |
+| 配置的提供方 id 已注册但不可用 | 以 `WEB_PROVIDER_CONFIGURED_UNAVAILABLE` 失败 |
+| 未配置提供方 id，且该类别恰好有一个已注册且可用的提供方 | 运行该唯一提供方 |
+| 未配置提供方 id，且该类别无已注册提供方 | 以 `WEB_PROVIDER_UNAVAILABLE` 失败 |
+| 未配置提供方 id，且该类别有多个可用提供方已注册 | 以 `WEB_PROVIDER_AMBIGUOUS` 失败，而非按注册顺序选择 |
+| 未配置提供方 id，且有提供方存在但均不可用 | 以 `WEB_PROVIDER_UNAVAILABLE` 失败 |
+
+「唯一提供方自动选择」规则面向测试、演示和简单部署。产品配置设置显式提供方 id：
+
+```yaml
+- id: web
+ name: '@deepseek-ai/dsh-web'
+ config:
+ searchProvider: exa
+ fetchProvider: local-http
+
+- id: web-search-exa
+ name: '@deepseek-ai/dsh-web-search-exa'
+
+- id: web-search-perplexity
+ name: '@deepseek-ai/dsh-web-search-perplexity'
+
+- id: web-search-deepseek
+ name: '@deepseek-ai/dsh-web-search-deepseek'
+
+- id: web-fetch-local
+ name: '@deepseek-ai/dsh-web-fetch-local'
+
+- id: tool-web
+ name: '@deepseek-ai/dsh-tool-web'
+```
+
+运维覆盖走同一条显式选择路径：`DSH_WEB_SEARCH_PROVIDER=perplexity` 等同于配置 `searchProvider: perplexity`，而非 `dsh-tool-web` 内部的隐式优先级链。
+
+`ctx.web.search()` 和 `ctx.web.fetch()` 在执行时按上述选择规则解析提供方。如果选定的能力不可用，它们抛出带有结构化代码的 `WebError`，如 `WEB_PROVIDER_UNAVAILABLE`、`WEB_PROVIDER_CONFIGURED_MISSING`、`WEB_PROVIDER_CONFIGURED_UNAVAILABLE` 或 `WEB_PROVIDER_AMBIGUOUS`。如果未显式配置提供方且不存在可用提供方，执行错误是通用的 `WEB_PROVIDER_UNAVAILABLE` 情况；刻意不提供对每个不可用提供方的诊断汇总。
+
+## 搜索请求与结果 schema
+
+面向模型的 `web_search` 工具很小。唯一的面向模型参数是：
+
+- `query`：必填字符串。
+
+`max_results` 不暴露给模型。它是 `dsh-tool-web` 层的决策：工具设定结果上限——`searchMaxResults` 插件配置，默认 `8`（与 OpenCode 的 Exa 默认值对齐），类似 `dsh-tool-fs` 的 `readLimit`——并作为 `WebSearchRequest` 上的 `maxResults` 传给 seam。将其排除在模型 schema 之外意味着模型只需提问，产品控制返回多少上下文；该字段日后可以提升为面向模型的参数而不破坏 seam。
+
+`maxResults` 沿工具 → seam → 提供方流动，上限在返回路径上强制执行：
+
+- `dsh-tool-web` 拥有该值并将其放在 `WebSearchRequest.maxResults` 上。
+- `ctx.web` 将请求原样传递给选定的提供方。
+- 当提供方的 API 支持结果数量控制时（Exa 的 `numResults`），提供方在请求层应用 `maxResults`，作为成本/延迟优化。
+- `ctx.web` 在结果上强制执行上限：如果提供方返回的 source 数量超过 `maxResults`——因为其 API 没有结果数量控制（Perplexity）或忽略了提示——seam 将 `sources[]` 截断到 `maxResults` 并在返回前将 `WebSearchResult.truncated` 设为 `true`。这使上限成为面向模型层可以依赖的单一跨提供方保证，而非每个提供方都必须记得遵守的东西。
+
+seam 请求不携带提供方特有的控制——没有 Perplexity 模型选择、搜索时效性、域名过滤器、Exa `livecrawl`、Exa `type`、区域提示、生成式回答预算或搜索深度。只有当某个字段具有提供方无关的语义，且工具 schema 和选定的提供方都能诚实地遵守时，才会添加。
+
+```ts
+interface WebSearchRequest {
+ readonly query: string
+ /** Upper bound on returned sources; the seam truncates to it. Omitted = no bound. `dsh-tool-web` always sets it. */
+ readonly maxResults?: number
+}
+
+interface WebSearchResult {
+ readonly content?: string
+ readonly sources: readonly WebSearchSource[]
+ readonly truncated: boolean
+}
+
+interface WebSearchSource {
+ readonly url: string
+ readonly title?: string
+ readonly snippet?: string
+ readonly publishedAt?: string
+}
+```
+
+`content` 是可选的提供方生成的回答文本、搜索上下文或摘要。`sources[]` 是可移植的引用面。source 必有 URL；title、snippet 和 `publishedAt` 可选，因为并非每个提供方都返回它们。`title` 不是必填：Perplexity 风格的引用可能只提供 URL，强制适配器编造标题会让 seam 说谎。`dsh-tool-web` 渲染 `title ?? hostname(url)` 风格的回退标签用于展示。`publishedAt` 是可选的发布/抓取时间戳，为 ISO-8601 字符串——Exa 在每条结果上以 `publishedDate` 返回它，Perplexity 在搜索结果上返回 `date`，因此它是真实的提供方数据而非派生值；seam 以字符串形式传递，日期解析留给消费方。
+
+Exa 搜索将提供方扁平 `results[]` 的每一项映射为 `WebSearchSource`：`url` ← `url`、`title` ← `title`、`snippet` ← 第一个 `highlights[]` 条目（没有 highlight 的条目没有可移植的 snippet，被丢弃）、`publishedAt` ← `publishedDate`。Exa 不返回提供方生成的回答，因此 `content` 省略。Perplexity 搜索将 `choices[0].message.content` 映射为 `content`，并优先使用结构化的顶层 `search_results[]` 作为 `sources[]`——`url` ← `url`、`title` ← `title`、`snippet` ← `snippet`（常为空）、`publishedAt` ← `date`——仅在 `search_results` 缺失时回退到纯 URL 的 `citations[]` 数组（这些 source 只有 `url`）。如果提供方返回的结构化字段少于 seam 支持的，适配器省略那些可选字段。
+
+完整页面获取仍是 `web_fetch(url)` 的职责。搜索 snippet 是发现上下文，不是获取到的页面正文。
+
+## Fetch 请求与结果 schema
+
+`web_fetch` 的实现是一个匿名公开 HTTP(S) fetch 提供方 `local-http`。它从具体 URL 获取字节，应用下述基本传输卫生措施（仅 http/https、拒绝 URL 中的凭证、字节/时间上限、跨源重定向阻断），解码文本内容，并仅返回最小的模型可用结果：最终 URL、状态码、正文和截断标志。它不携带浏览器 cookie、编辑器凭证、git 凭证、内部认证令牌，也不隐式访问私有服务。（完整的 SSRF/私有网络阻断推迟——见[推迟工作](#deferred-work)。）
+
+seam 请求比 OpenCode 的面向模型工具更小：
+
+- `url`：必填 HTTP(S) URL。
+
+seam 请求刻意不包含逐调用超时、`format`、`prompt` 或提供方特有的提取控制。取消通过直接的可选执行信号实现，fetch 提供方拥有一个部署配置的超时兜底。`format` 是对已获取资源的展示决策；`prompt` 是更高层的 LLM 摘要指令；Firecrawl、Exa、Tavily 或 Parallel 等提取 API 可能不暴露具体的 HTTP 响应。如果产品日后需要提供方支撑的页面提取，那是一个独立的 `web_extract` 能力或对本 seam 的刻意扩展——提取语义绝不通过将每个 HTTP 字段设为可选来偷渡进 `web_fetch`。
+
+HTTP 状态码是已获取资源状态的一部分，不自动构成工具失败。成功的网络获取一个 `404` 或 `500` 响应会返回带有状态码和有界解码正文（当内容类型受支持时）的 `WebFetchResult`。`WebError` 用于无法安全获取或表示资源的失败：无效或被阻断的 URL、重定向策略违规、超时、abort、响应过大、不支持的内容类型、提供方失败或网络失败。
+
+```ts
+export interface WebFetchRequest {
+ readonly url: string
+}
+
+export interface WebFetchResult {
+ readonly url: string
+ readonly statusCode: number
+ readonly body: WebFetchBody
+ readonly truncated: boolean
+}
+
+export type WebFetchBody =
+ | { readonly kind: 'html'; readonly content: string }
+ | { readonly kind: 'text'; readonly content: string }
+```
+
+`WebFetchResult.url` 是允许的重定向之后的最终 URL。请求 URL 已在 `WebFetchRequest` 中，因此没有单独的 `requestedUrl`/`finalUrl` 对。
+
+`WebFetchBody` 是封闭的可辨识联合类型，因为正文类别需要 seam、提供方和工具三方协调变更，而非独立的插件扩展。穷举 switch 使新类别在每个渲染器处编译失败，直到被处理。独立的对象分支为类别特有字段留出空间。
+
+提供方负责安全的资源获取：URL 校验、HTTP 传输、重定向策略、超时、abort 传播、字节上限、字符集解码、内容类型分类和二进制拒绝。`dsh-tool-web` 负责展示：HTML 转 Markdown、HTML 转纯文本、面向模型的截断格式化，以及未来的摘要。
+
+fetch 提供方的资源控制：
+
+- 仅接受 `http:` 和 `https:` URL；拒绝 URL 中的凭证。
+- 强制执行最大 URL 长度、响应字节上限、解码正文字符上限、超时和重定向跳数上限。
+- Abort 信号传播到网络获取和高开销解码。
+- 仅自动跟随同源重定向；跨源重定向以 `WEB_REDIRECT_BLOCKED` 失败，要求一次新的工具调用，从而触发新的提供方/权限决策。（Claude Code 的 WebFetch 使用同样的模型——它不自动跟随跨主机重定向，而是将重定向目标返回给模型以发起新调用。）
+- 请求携带显式的产品 User-Agent，而非静默伪装浏览器。
+
+SSRF/私有网络防护（阻断私有、回环、链路本地、多播及其他非公开目的地，通过先 DNS 解析再验证 IP 来防御 rebinding，并在重定向的每一跳重新验证）**推迟**——见[推迟工作](#deferred-work)。在其落地之前，`web_fetch` 是一个 SSRF 原语，不得在能触达敏感内部网络目标的部署中启用。
+
+## 工具消费方行为
+
+`dsh-tool-web` 拥有两个 `ToolDefinition`：`web_search` 和 `web_fetch`。它拥有面向模型的 JSON Schema、snake_case 参数名、提示词段落、结果渲染为 `ContentBlock[]`、`presentCall` 和 `presentResult`。
+
+`dsh-tool-web` 禁止枚举提供方或直接调用提供方的 `available()`。它进入 seam 的唯一路径是 `ctx.web.search()`/`ctx.web.fetch()`。这将提供方选择保持在单一层；否则工具包可能判定某个提供方可用，而执行时解析出不同的状态。
+
+工具注册是最小化的稳定同步：插件启动时，`dsh-tool-web` 的 `Config`（`search?: boolean`、`fetch?: boolean`，均默认 `true`）启用或禁用每个 web 工具；已启用的工具通过基于 effect 的注册表以 fiber 作用域的 disposer 注册；任何工具都不会仅因其选定的提供方缺失、不可用或存在歧义而被 dispose；dispose `tool-web` fiber 时自动拆除其注册。
+
+提供方可用性变化影响执行结果和诊断信息，而非面向模型的 schema 是否存在。如果产品完全不需要 web 工具，在配置中禁用 `dsh-tool-web` 或单个 web 工具即可；如果需要 web 工具但后端配置有误，模型在执行时看到结构化的工具错误。
+
+提示词引导解释了语义分工——`web_search` 用于发现和获取当前信息，`web_fetch` 用于模型需要特定 URL 内容的场景——提示词和工具结果告诉模型用 Markdown 链接引用相关 URL。
+
+面向模型的输出以文本为先，因为工具结果是 `ContentBlock[]`，但 seam 的产出保持结构化，以便 UI 展示和未来的适配器无需解析渲染后的文本。
+
+## 错误
+
+`dsh-web` 定义 `WebError extends HarnessError`，带有稳定的错误码，仅覆盖调用方可能合理分支的状态：
+
+- `WEB_PROVIDER_UNAVAILABLE`
+- `WEB_PROVIDER_CONFIGURED_MISSING`
+- `WEB_PROVIDER_CONFIGURED_UNAVAILABLE`
+- `WEB_PROVIDER_AMBIGUOUS`
+- `WEB_DUPLICATE_PROVIDER`
+- `WEB_INVALID_URL`
+- `WEB_BLOCKED_URL`
+- `WEB_REDIRECT_BLOCKED`
+- `WEB_FETCH_TOO_LARGE`
+- `WEB_FETCH_TIMEOUT`
+- `WEB_ABORTED`
+- `WEB_UNSUPPORTED_CONTENT_TYPE`
+- `WEB_PROVIDER_ERROR`
+
+`WEB_DUPLICATE_PROVIDER` 在 `registerSearchProvider`/`registerFetchProvider` 发现该能力类别中已有相同 id 时同步抛出（类似 `LlmService` 的 `DUPLICATE_ADAPTER`）；它是注册时的编程错误而非执行结果，但共享 `WebError` 码空间，使调用方看到统一的分类体系。`WEB_PROVIDER_ERROR` 是提供方自身失败通过 seam 浮出的兜底码，包括 `web-fetch-local` 中的网络/传输失败（DNS、连接拒绝、TLS）；刻意不设单独的 `WEB_NETWORK` 码——提供方设置描述性消息，使模型和日志能区分网络失败与提供方 API 失败。
+
+工具执行让这些错误流经 `ToolRegistry.execute()`，后者已将 `HarnessError` 转换为带结构化元数据的错误工具结果。模型得到可读的错误消息；钩子、测试和 UI 代码可以根据稳定的错误码路由。
+
+## 测试
+
+每一层在自己的 seam 处固定：`dsh-web` 中的注册/选择/截断/abort 契约与 `WebError` 码；每个提供方基于录制的 fixture（测试前置数据）的请求/响应映射（Perplexity fixture 包含纯 URL 引用，以保持可选 source 字段的诚实性），加上每个真实提供方的自跳过带密钥冒烟测试；`web-fetch-local` 中的真实本地 HTTP 行为；`dsh-tool-web` 中通过真实工具注册表的启用驱动注册、结构化执行错误和结果格式化。一个真实 Loader 冒烟测试守护两种导出形状（[事后分析 0001](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md)）：`dsh-web` 是默认导出的服务，而提供方和 `tool-web` 是命名空间插件，误加 `export default` 会丢失 `inject`。
+
+## 曾考虑的替代方案
+
+### 让每个提供方注册自己的面向模型工具
+
+这与最灵活的提供方插件系统一致：每个提供方可以暴露其完整的原生 schema。在 harness 中被否决，因为它将面向模型的名称、描述、提示词引导和结果格式化的所有权交给了提供方包。多个搜索提供方会产生重复的工具名或提供方特有的工具名，模型将学到后端细节而非稳定的产品能力。
+
+### 将提供方调度直接放在 `dsh-tool-web` 中
+
+这类似 OpenCode 的本地 web 搜索：一个稳定的 `websearch` 工具在内部调度到 Exa 或 Parallel。对于小型产品路径可以接受，但作为 harness 基础是错误的。工具包将拥有提供方选择、凭证、请求映射、传输、响应解析和展示，使得在不将 Exa 和 Perplexity 的差异烘焙进工具 schema 的情况下难以添加它们。
+
+### 将搜索和 fetch 拆为两个 seam（`dsh-search`、`dsh-fetch`）
+
+很有吸引力，因为两半不共享请求 schema 和业务逻辑，各自能干净地映射到 bash/fs 的三包模板上，且 `WebService` 上的 `Search`/`Fetch` 方法对重复也会消失。否决，因为共享的机制——提供方 id 注册表、不依赖注册顺序的选择策略、abort 传播、`WebError` 分类体系，以及面向产品的「这个 harness 如何触达 web」配置面——是真实存在的，否则会在两个几乎相同的 seam 之间重复。一个 `ctx.web` 中间层给产品一个统一的注入和配置对象，给提供方选择一个唯一的所有者。代价是并行的 `searchX`/`fetchX` 方法对，这是有意接受的。
+
+### 选择第一个注册的提供方
+
+否决。注册顺序不是产品策略。它可能随配置顺序、插件加载、HMR 或重构而变化。提供方选择必须是显式的，或仅在恰好只有一个可用提供方时自动选择。
+
+### 将 Firecrawl/Exa/Tavily/Parallel 提取视为 fetch
+
+在第一版中否决。这些提供方通常返回提取或摘要后的内容，而非具体的 HTTP 响应。如果产品需要提取，日后设计 `web_extract` 或刻意扩展 fetch seam。
+
+### 镜像 Claude Code 的 `url + prompt` WebFetch 形状
+
+在 seam 层面否决。`prompt` 将 fetch 变成 LLM 摘要，并将公开 web 获取耦合到模型提供方。harness seam 应当确定性地获取和解码；`dsh-tool-web` 日后可以将摘要作为展示模式提供，而无需让 `ctx.web` 依赖 `ctx.llm`。
+
+## 后果
+
+**搜索 schema 刻意精简。** Exa 和 Perplexity 都暴露了有用的提供方特有控制；只有当某个控制能以提供方无关的方式定义、且工具注册和提供方执行都能诚实遵守时，才会添加。
+
+**Perplexity 引用可能稀疏。** 一条引用可能只有 URL。将 `title` 和 `snippet` 设为可选使 seam 保持诚实，但意味着 `tool-web` 需要渲染回退标签。
+
+**稳定的工具注册将配置错误推迟到执行时。** 当产品启用了 web 访问时，保持工具可见是正确的；但期望 web 搜索可用的产品应用应当醒目地浮出结构化的 `WEB_PROVIDER_CONFIGURED_MISSING`/`WEB_PROVIDER_CONFIGURED_UNAVAILABLE`/`WEB_PROVIDER_AMBIGUOUS` 失败，使用户不会在模型调用工具后才发现配置问题。
+
+**提供方状态可能在启动后变化。** 一个工具可能在步骤开始时组装的请求中可见，但在执行前失去其提供方。执行路径重新解析并以结构化错误失败。
+
+**Fetch 是网络边界，不仅仅是只读工具。** `web_fetch` 能触达敏感网络目标或通过 URL 外泄数据。仅交付基本传输卫生措施（仅 http/https、拒绝凭证、字节/时间上限、跨源重定向阻断）；SSRF/私有网络阻断推迟（见[推迟工作](#deferred-work)），因此在其落地之前，`web_fetch` 不得在能触达内部目标的环境中启用。
+
+**大量 web 内容可能损害上下文质量。** 提供方强制执行字节/字符上限并报告 `truncated`；`tool-web` 格式化有界的模型输出，附带清晰的继续或后续引导。
+
+## 推迟工作
+
+- `web_fetch` 的 SSRF/私有网络防护：阻断私有、回环、链路本地、多播及其他非公开目的地，使 `web_fetch` 不再是 SSRF 原语。正确实现不仅仅是 URL 字符串检查——需要先 DNS 解析再连接到已验证的 IP（防御 DNS rebinding/TOCTOU）、跨重定向的每跳重新验证，以及 IPv6 边缘处理（私有范围、IPv4 映射地址）。所调研的参考实现均未做 IP 级阻断（OpenCode 做前缀检查后直接 fetch；Claude Code 依赖集中式主机名黑名单加「私有 URL 会失败」的提示词），因此没有可复制的实现，且这是 harness 唯一的 SSRF 防线——值得一次专门的设计/spike。在其落地之前，`web_fetch` 只能在无法触达敏感内部目标的部署中启用。
+- `pdf` `WebFetchBody` 类别：`local-http` 提供方将可文本提取的 PDF 解码（尽力而为、有上限、`truncated`）为 `{ kind: 'pdf'; content; pageCount? }` 分支，`tool-web` 渲染它。这是 fetch 而非 `web_extract`——PDF 获取是具体的 HTTP 200 加确定性的本地解码，不是提供方侧对非 HTTP 资源的提取。添加它是跨 `dsh-web`（声明分支）、提供方（解码 + 将「二进制拒绝」收窄为「拒绝二进制，但可文本提取的 PDF 除外」；需要 OCR 的扫描/图片 PDF 不在范围内）和 `tool-web`（渲染）的协调变更。封闭的 `WebFetchBody` 联合类型使消费方在新分支被处理之前编译失败。
+- 提供方支撑的提取作为独立的 `web_extract` 能力，而非静默扩展 `web_fetch`。
+- 推迟的权限系统落地后的权限策略集成。
+- `query` 和 `maxResults` 之外的提供方无关搜索控制，待 Exa 和 Perplexity 都能诚实遵守时再添加。
+
+## 开放问题
+
+- 产品应用包是否应在启动时探测 web 配置（当 web 被显式配置时将 `WEB_PROVIDER_CONFIGURED_MISSING`、`WEB_PROVIDER_CONFIGURED_UNAVAILABLE` 和 `WEB_PROVIDER_AMBIGUOUS` 视为致命错误），还是将配置错误留到首次执行时浮出？
+- 推迟的权限系统落地后，公开 web 访问的权限策略应放在哪里：`tools/execute` 上的专用 web 权限插件、提供方配置，还是两者兼有？

## Problem
[The split-fs-seam Agent Note](../simplification/2026-06-26-fsspec-style-fs-seam.md) put `ctx.fileContext` between the model-facing tools and the `ctx.fs` provider: `dsh-tool-fs` injects `fileContext` and routes every `read`/`write`/`edit` through its methods. That makes `fileContext` **in-path and mandatory**. The tool cannot reach `ctx.fs` without it, the policy layer owns the fs I/O and the read windowing, and a deployment that does not want observed-state policy cannot simply drop the package — `dsh-tool-fs` would fail to resolve `ctx.fileContext`.

+# Agent Note: 将 `dsh-fs-policy` 改为事件门控插件，而非方法接口

+Status: implemented

+
+## 问题
+
+[拆分文件系统 seam Agent Note（agent 决策记录）](../simplification/2026-06-26-fsspec-style-fs-seam.md) 在面向模型的工具与 `ctx.fs` 提供方之间放置了 `ctx.fileContext`：`dsh-tool-fs` 注入 `fileContext`，并将每次 `read`/`write`/`edit` 路由到它的方法。这使得 `fileContext` **位于关键路径上且不可省略**。工具不经过它就无法访问 `ctx.fs`，策略层掌控着 fs I/O 和读取窗口，而一个不需要观测状态策略的部署也无法简单地移除该包——`dsh-tool-fs` 会因无法解析 `ctx.fileContext` 而失败。
+
+这把三件本应可分离的事情耦合在了一起：
+
+1. **工具做什么**——解析路径、读取窗口、写入/编辑文件。这是工具的职责，只需要 `ctx.fs`。
+2. **新鲜度/观测策略**——「编辑前必须先读」、「写入/编辑必须基于你读到的版本」。这是 `dsh-fs-policy` 插件的职责。
+3. **观测状态的记录**——一个副作用，永远不应阻止工具正常运行。
+
+由于工具调用的是 `fileContext` 方法，移除策略层就是一个破坏性变更，而非优雅地失去一个*附加*能力。策略层对工具的运行是承重性的，而非可选的收紧。
+
+## 决策
+
+反转控制流。**`dsh-tool-fs` 成为执行器，直接调用 `ctx.fs`**；**`dsh-fs-policy` 成为门控 + 记录插件**，通过事件参与，从不通过工具调用的方法，也不注册 `ctx.fileContext` 服务。
+
+```text
+tool dsh-tool-fs executor: resolves, reads windows, writes/edits via ctx.fs;
+ emits fs policy events; renders results
+policy dsh-fs-policy plugin: listens to fs/write-intent +
+ fs/edit-intent (single-slot waterfall) and fs/observed
+ (emit) events; adds observed-state + freshness.
+provider seam dsh-fs ctx.fs: text IO + ATOMIC mutation primitives whose version
+ guard is OPTIONAL; owns the fs policy event vocabulary
+provider dsh-fs-local local implementation of ctx.fs
+```
+
+该模型是叠加式的：裸 `ctx.fs` 执行原子化、无约束的文本 I/O，而 `dsh-fs-policy` 叠加观测状态、先读后编辑和版本守卫。因此移除策略层后工具仍可用，只是不受约束。正式发布的 agent 配置会加载策略；裸模式的存在是为了让策略在服务边界保持可选，而非作为正常部署姿态。
+
+`dsh-tool-fs` 不再注入 `fileContext`。它注入 `fs` 和 `tools`/`systemPrompt`。
+
+## 策略由提供方 CAS 强制执行，而非 `dsh-fs-policy` 的 stat
+
+`dsh-fs-policy` 强制执行「你必须基于你读到的版本来写入/编辑」，**自身从不调用 `stat` 或比较版本**。它将观测到的版本作为 CAS 基准提供，让提供方的 mutation 临界区检测陈旧性：
+
+- 「你读过这个文件吗？」是 `dsh-fs-policy` 在本地决定的唯一事项——一次 `WeakMap` 查找，无 I/O。无记录 ⇒ `FS_NOT_OBSERVED`。
+- 「你读到的版本是否仍为最新？」由 **`ctx.fs.editText`/`writeText` 内部**决定，在执行 read-match-rename 的同一个原子锁中完成。`dsh-fs-policy` 将 `vObserved` 作为期望值传入；如果文件已变更，提供方抛出 `FS_STALE_VERSION`。
+
+这是有意为之的。如果 `dsh-fs-policy` 在其 waterfall（瀑布式事件）处理器中 stat 并比较版本，该检查与工具实际写入之间会存在 TOCTOU 间隙——文件可能在此期间变化，因此该检查只是一个虚假保证，提供方的锁无论如何都要兜底。将版本检查放在提供方的临界区中既无竞态又无额外 `stat`。所以 `dsh-fs-policy` **不做**任何文件系统 I/O；「必须基于最近一次读取」的保证由 CAS *实现*，`dsh-fs-policy` 只负责选择基准（`vObserved`）并对先前观测进行门控。
+
+## 提供方契约变更：版本守卫变为可选
+
+为使裸提供方不受约束，其两个 mutation 上的版本守卫变为**可选**——传入则守卫，省略则无条件执行：
+
+```ts ignore-check
+// writeText: expected is now optional. The FsWriteIntent union is UNCHANGED.
+writeText(target: FsTarget, content: string, expected?: FsWriteIntent, signal?: AbortSignal): Promise<FsWriteOutcome>
+// undefined → unconditionally create-or-overwrite (bare default)
+// createIfAbsent → create only, reject an existing file (dsh-fs-policy, unobserved) [unchanged]
+// replaceIfVersion → overwrite only at the observed version, else FS_STALE_VERSION [unchanged]
+
+// editText: expected becomes optional (was the required { version: FsVersion }).
+editText(target: FsTarget, edit: FsEditRequest, expected?: { version: FsVersion }, signal?: AbortSignal): Promise<FsEditOutcome>
+// undefined → unconditionally replace literal text in the current content (bare default);
+// a missing target still reports FS_STALE_VERSION
+// { version } → edit only at that version, else FS_STALE_VERSION (the current behavior)
+```
+
+`FsWriteIntent` 联合类型本身不变——第三种「无条件」状态通过*省略* `expected` 来表达，因此两个 mutation 共享同一种对称形状（`expected?`：省略 = 无守卫，传入 = 有守卫）。这对 `dsh-fs-policy` 使用的有守卫路径保持完全向后兼容；只有之前不可能出现的「无守卫」情况是新增的，且它是裸提供方的默认行为。无论哪种情况，mutation 仍在后端的 per-target 锁内运行，因此无条件写入/编辑仍是原子的（不会产生撕裂文件）；「无条件」去掉的是*版本*前置条件，而非原子性。`editText` 在有守卫和无守卫路径上都将缺失目标报告为 `FS_STALE_VERSION`，保持一个统一的编辑失败码表示「此刻无法编辑该目标」。
+
+## 事件词汇（由 `dsh-fs` 拥有）
+
+事件定义在 `@deepseek-ai/dsh-fs` 中，而非 `dsh-fs-policy` 中。这是解耦契约所迫：`dsh-tool-fs` 是发射方，因此它必须引用事件类型，且即使 `dsh-fs-policy` 不再提供方法服务，它也必须能编译通过。`dsh-fs` 是 `dsh-tool-fs` 和 `dsh-fs-policy` 都已依赖的包，因此它是唯一能让发射方和策略监听方共享词汇而不让发射方依赖策略插件的归属地。
+
+这些事件携带既有的 `dsh-fs` 词汇（`FsTarget`、`FsVersion`、`FsWriteIntent`）加一个不透明的 actor——不携带面向模型的概念（行窗口、行号或渲染后的页脚不会泄漏到此层）。
+
+**两个 `fs/*` 决策事件是单槽、先到先得的 waterfall。** `dsh-fs-policy` 不调用 `next()` 直接返回，因此在默认部署中它占据该槽位；更早注册或使用 `prepend` 的监听器会替代该策略。权限、审计和沙箱关注点仍留在可组合的 `tools/execute` waterfall 上。
+
+actor 在 `dsh-fs` 中类型为 `object`——一个纯粹的不透明载体，提供方 seam 从不读取或收窄它。owner 的推导（`actor.agent?.session`）和 `{ agent?: { session? } }` 结构形状完全留在 `dsh-fs-policy` 内部，由其在监听器中将 `object` actor 收窄为该形状。`dsh-fs` 拥有事件名和 fs 词汇；它不拥有策略层的运行时 owner 结构。
+
+```ts
+import type { FsTarget, FsVersion, FsWriteIntent } from '@deepseek-ai/dsh-fs'
+
+interface Events {
+ /**
+ * Single-slot decision: produce the write expectation for the next
+ * ctx.fs.writeText. The default returns undefined (unconditional create-or-
+ * overwrite — the bare provider). The policy listener returns createIfAbsent
+ * (unobserved) or { kind: 'replaceIfVersion', version: vObserved } (observed).
+ * The listener does NOT call next(): one decision, not a composable chain. @mode waterfall
+ */
+ 'fs/write-intent'(target: FsTarget, actor: object | undefined, next: () => FsWriteIntent | undefined | Promise<FsWriteIntent | undefined>): Promise<FsWriteIntent | undefined>
+ /**
+ * Single-slot decision: produce the optional version guard for the next
+ * ctx.fs.editText. The default returns undefined (unconditional edit of the
+ * current content — the bare provider; no stat). The policy listener returns
+ * { version: vObserved }, or throws FS_NOT_OBSERVED if the actor is unset or
+ * has not observed the target. Does NOT call next(): one decision. @mode waterfall
+ */
+ 'fs/edit-intent'(target: FsTarget, actor: object | undefined, next: () => { version: FsVersion } | undefined | Promise<{ version: FsVersion } | undefined>): Promise<{ version: FsVersion } | undefined>
+ /**
+ * Record that an actor observed a target at a version, after a successful
+ * read/write/edit. Fire-and-forget (plain emit). Listeners MUST be
+ * synchronous, side-effect-only recorders (`dsh-fs-policy`'s is a WeakMap
+ * write); the tool does not guard the emit, so a throwing listener surfaces as
+ * the tool's isError result. No listener ⇒ nothing recorded.
+ * @mode emit
+ */
+ 'fs/observed'(target: FsTarget, version: FsVersion, actor: object | undefined): void
+}
+```
+
+`fs/*` 决策事件是**由工具分发的无绑定 waterfall**（类似 `agent/request`，由循环分发且无 `this`），而非服务绑定的 waterfall（如 `llm/stream`）。分发者是 `dsh-tool-fs` 插件，它不是一个服务。
+
+## 工具契约（`dsh-tool-fs`）
+
+工具保留其面向模型的 schema（`read`/`write`/`edit`，逐字节不变）和提示词段落。提示词引导仍以策略优先，因为加载 fs 工具的部署预期也会加载 `dsh-fs-policy`：模型仍被告知在覆写或编辑前先读取，任何声称「后端」要求如此的措辞应修正为 fs-policy 插件要求如此。裸提供方回退不改变提示词立场。
+
+`dsh-tool-fs` 获得从旧 `fileContext` 方法服务迁移来的执行器职责，包括**读取渲染**（`read-render.ts`：`buildWindow` + `formatReadOutput`、`READ_MAX_BYTES`、`READ_MAX_LINE_LENGTH`、`FileReadOutcome`/`FileTextLine`，以及 `read.ts` 中的 `STREAM_MIN_SIZE`），这些现在是工具的渲染细节，因为读取已由工具拥有。这些读取渲染类型和辅助函数移入 `dsh-tool-fs`；策略插件不得继续作为工具的类型依赖。
+
+`dsh-tool-fs` 是一个注册全部三个工具（`read`/`write`/`edit`）的单一根插件，与 `dsh-tool-bash` 相同。它注入 `fs`（加 `tools`/`systemPrompt`），从不注入 `fileContext`。（最初的提案还将每个工具作为 `/read`/`/write`/`/edit` 子路径插件暴露，供聚焦部署使用；实现时被放弃——没有消费方需要单工具部署，且子路径发布迫使引入兄弟工具包都不需要的定制 `tsdown`/`tsconfig`/`files`/workspace-constraint 处理。每工具的注册辅助函数（`applyReadTool`/`applyWriteTool`/`applyEditTool`）仍作为根插件组合的内部模块保留。）
+
+通过让 waterfall 惰性产出期望值来最小化 `stat` 预算——裸默认返回 `undefined`（无守卫），从不 stat：
+
+- **read**——一次 `stat`（类型 + 大小路由 + 版本），然后 `readText`/`streamText`，然后 `buildWindow`，然后 `emit('fs/observed', target, info.version, exec)`。旧 `fileContext.read` 中读后确认的 `stat` 被移除；在路由 stat 和读取之间竞争的写入者最多只能使*后续*有守卫的编辑误报 `FS_STALE_VERSION`（为安全起见拒绝写入：模型会重新读取；由于 `editText` 会在其锁内复查，模型绝不会基于错误版本写入）。
+- **write**——`expectation = await ctx.waterfall('fs/write-intent', target, exec, () => undefined)`，然后 `ctx.fs.writeText(target, content, expectation)`，然后 `emit('fs/observed', target, outcome.version, exec)`。无论是否有 `dsh-fs-policy`，**工具内零 stat**。
+- **edit**——`expectation = await ctx.waterfall('fs/edit-intent', target, exec, () => undefined)`，然后 `ctx.fs.editText(target, edit, expectation)`，然后 `emit('fs/observed', target, outcome.version, exec)`。两种情况下**工具内零 stat**：裸默认为 `undefined`（无条件编辑），因此工具从不 stat 来制造基准。如果目标不存在，提供方即使在无守卫路径上也报告 `FS_STALE_VERSION`。
+
+工具在每次分发时将 `exec`（工具执行上下文）作为 `actor` 参数传入，以便 `dsh-fs-policy` 推导其观测状态的 owner。工具不知道策略插件是否存在：它始终在 `next` thunk 中提供裸默认行为，而 `dsh-fs-policy` 在默认部署中会在 thunk 运行前短路它。
+
+**`fs/observed` 在操作成功后触发。** 其监听器必须是同步、不抛异常的记录器；工具不对 plain emit 做保护，因此抛异常的监听器会在 mutation 已成功后报告失败。异步或可失败的观测需要另一份事件契约。
+
+## 策略插件契约（`dsh-fs-policy`）
+
+`dsh-fs-policy` 是插件，不是服务。它不注册 `ctx.fileContext`，没有公开方法面，不暴露 `read`/`write`/`edit`/`resolve` 方法。它通过 `ctx.on()` 注册三个监听器（每个返回一个 disposer 用于 HMR）。它维护观测状态 `WeakMap<owner, Map<targetKey, { version }>>`，以及结构化的 owner 推导（将事件中不透明的 `object` actor 收窄为自己的 `{ agent?: { session? } }` 形状），但不注入 `fs`——每个处理器只操作自己的 `WeakMap`，从不操作 `ctx.fs`。
+
+- `fs/write-intent` 监听器：`prior = getObserved(owner, key)`；返回 `prior ? { kind: 'replaceIfVersion', version: prior.version } : { kind: 'createIfAbsent' }`。它不调用 `next()`：完全占据单一决策槽位。
+- `fs/edit-intent` 监听器：`prior = getObserved(owner, key)`；如果无 `owner` 或无 `prior`，抛出 `FS_NOT_OBSERVED`；否则返回 `{ version: prior.version }`。同样不调用 `next()`。
+- `fs/observed` 监听器：`record(owner, key, version)`。
+
+一条观测状态条目是**先前观测记录**：成功的 `read`、`write` 或 `edit` 都会 emit `fs/observed` 并记录 `{ version }`，因此条目的存在意味着「此 owner 在此版本观测过此目标」，而非狭义的「已读取过」。这使得 create-then-edit 或 edit-then-edit 序列无需中间重新读取即可工作：mutation 将记录的版本刷新为自身的结果，因此下一次编辑的基准就是它刚产出的版本。`FS_NOT_OBSERVED` 只拒绝完全没有任何先前观测的编辑。owner 从 `{ agent?: { session? } }` 结构化推导；dispose 时丢弃所有状态（HMR 安全）。
+
+`dsh-fs-policy` 现在是一个纯策略/记录插件，没有服务面——它只通过事件 seam 影响外界。这正是移除 `dsh-tool-fs` 方法耦合的关键。
+
+## 裸提供方行为（无 `dsh-fs-policy`）
+
+这不是预期的部署姿态——加载 fs 工具的配置预期也会加载 `dsh-fs-policy`。它是工具不再耦合于策略方法服务后所存在的无约束提供方下限。当 `dsh-fs-policy` 不存在时，每个 `fs/*` waterfall 落入其 `undefined` 默认值，`fs/observed` 无监听器：
+
+- **read** 行为不变（它从不需要策略；只是 emit 了一个现在无人监听的 `fs/observed`）。
+- **write** 无条件 create-or-overwrite：`expected` 为 `undefined`，因此 `writeText` 无论文件是否存在、无论当前版本如何都直接写入。无先读要求，无版本检查。
+- **edit** 无条件替换文件当前内容中的字面文本：`expected` 为 `undefined`，因此 `editText` 无版本守卫、无先读要求地匹配并重写（`FS_EDIT_NOT_FOUND`/`FS_AMBIGUOUS_EDIT` 仍适用——它们关乎字面匹配，而非新鲜度）。缺失目标仍报告 `FS_STALE_VERSION`，与有守卫编辑路径的「此刻无法编辑该目标」错误码一致。
+
+两个 mutation 仍是原子的（后端的 per-target 锁是无条件的）。仅仅是*不存在*（而非丢失）的是 `dsh-fs-policy` 本会叠加的策略：观测状态、先读后编辑和版本守卫的写入/编辑。加载 `dsh-fs-policy` 后，其监听器返回有守卫的 `expected` 值而非 `undefined`，从而叠加这些约束；裸提供方本身无需任何变更。
+
+## 取代关系
+
+本 Agent Note 修正——而非推翻——[拆分文件系统 seam Agent Note](../simplification/2026-06-26-fsspec-style-fs-seam.md)。四层拆分、提供方契约和新鲜度*策略*均保留。变更的是**工具与策略层之间的耦合方式**：强制性方法服务变为插件拥有的事件门控，fs I/O + 读取窗口从 `fileContext` 上移至 `dsh-tool-fs`。拆分文件系统 seam Agent Note 中关于 `dsh-tool-fs` 注入 `fileContext` 以及 `fileContext` 拥有 `read`/`write`/`edit` 的描述已在同一变更中更新。
+
+## 验证
+
+测试固定了两条路径：无 `dsh-fs-policy` 时，根工具插件对 `dsh-fs-local` 启动，read、create、overwrite 和未读 edit 均成功；有策略时，未读 edit 返回 `FS_NOT_OBSERVED`，未读 overwrite 被 `createIfAbsent` 门控。策略决定后，后注册的 intent 监听器不会被触达。陈旧编辑通过提供方 CAS 失败，而策略不执行 `stat`；工具预算在两条路径上保持 read 一次 `stat`，write 或 edit 均为零次。面向模型的 schema 逐字节不变，因此快照不变。
+
+## 曾考虑的替代方案
+
+- **保留 `ctx.fileContext` 作为关键路径上的方法服务**——[拆分文件系统 seam Agent Note](../simplification/2026-06-26-fsspec-style-fs-seam.md) 最初落地的形态；否决，因为工具无法在没有策略层的情况下运行，使策略对基本操作是承重性的，而非可选的收紧。
+- **策略侧版本检查**（`dsh-fs-policy` 在其 waterfall 处理器中 stat 并比较版本）——否决，因为该检查与工具实际写入之间存在 TOCTOU 间隙；提供方的 mutation 临界区是唯一无竞态的位置，因此策略只选择 CAS 基准并对先前观测进行门控。
+- **每工具 `/read`/`/write`/`/edit` 子路径插件**——实现时放弃：没有消费方需要单工具部署，且子路径发布迫使引入兄弟工具包都不需要的定制 `tsdown`/`tsconfig`/`files`/workspace-constraint 处理；每工具的注册辅助函数仍作为根插件组合的内部模块保留。
+
+## 后果
+
+- **事件间接层取代方法调用。** 一次 waterfall + emit 不如 `await ctx.fileContext.edit(...)` 直接。收益是移除了工具到策略的方法依赖，同时保留默认策略插件；代价是多一套事件词汇需要学习。通过保持三个事件的窄小范围并在每个事件上记录 default-thunk 语义来缓解。
+- **策略事件位于存储 seam 中。** `dsh-fs` 增加了两个版本决策事件和一个记录事件，尽管它「只是存储」。这是解耦的代价（发射方不能依赖策略插件）。这些事件只携带 `dsh-fs` 词汇加一个不透明的 `object` actor，不携带面向模型的概念，因此 seam 不沾染行窗口/观测策略类型，也不沾染 agent/会话所有者结构。
+- **单一策略占位者，按约定先到先得。** `fs/write-intent`/`fs/edit-intent` 槽位恰好容纳一个决策者；先注册（或 `prepend`）的监听器获胜，其余被短路。`dsh-fs-policy` 占据该槽位是部署约定，而非事件系统强制的不变式——一个先注册的第二决策者会绕过它。这是可接受的，因为第二个 fs 版本策略决策者是配置错误，而非功能。如果未来出现*分层* fs 版本策略的需求，那是一个新 Agent Note（可组合的值传递 seam），而非在这些事件上静默添加第二个监听器。分层的权限/审计/沙箱拦截已有其归属：`tools/execute`。
+- **移除读后确认 stat** 使后续*有守卫*的编辑在 read/write 竞争下偶尔为安全起见拒绝写入（`FS_STALE_VERSION` → 重新读取）。这是丢失的 UX 便利，绝非正确性漏洞；提供方锁仍阻止基于错误版本的写入。
+- **裸提供方不做先读后写/编辑，也不做版本检查。** 没有 `dsh-fs-policy` 的部署允许模型无条件覆写或编辑任何已有文件。这正是保持工具独立于策略服务的有意含义：安全纪律存在于 `dsh-fs-policy` 插件中。省略它的部署是有意选择无约束的文件系统；对于发布 fs 工具的配置而言，这不是预期的姿态。

## Problem
The hooks subsystem runs external hook commands the way Claude Code and Codex do: a hook is a shell command that receives its event payload as **JSON on stdin** and reads context from a handful of **environment variables** (`CLAUDE_PROJECT_DIR`, `CLAUDE_PLUGIN_ROOT`, `PLUGIN_ROOT`, …). The harness already has a perfectly good command runner behind the `ctx.bash` capability seam ([dsh-bash](../../../../packages/bash/bash) → [dsh-bash-local](../../../../packages/bash/bash-local)), with process-group kills, output truncation/spill, and a credential scrub. Reusing it for hook execution means a hook bridge does not re-implement subprocess plumbing — but the seam had no way to write stdin or set extra env. This Agent Note adds those two inputs.

+# Agent Note: 在 bash seam 上支持 stdin 与额外 env
+
+Status: implemented
+
+[English](2026-06-30-bash-stdin-env-trusted-plugin-surface.md) | 中文
+
+## 问题
+
+钩子子系统以 Claude Code 和 Codex 的方式运行外部钩子命令：钩子是一条 shell 命令，通过 **stdin 上的 JSON** 接收事件载荷，并从若干**环境变量**（`CLAUDE_PROJECT_DIR`、`CLAUDE_PLUGIN_ROOT`、`PLUGIN_ROOT`……）读取上下文。harness 已经在 `ctx.bash` 能力 seam 后面有一个完善的命令执行器（[dsh-bash](../../../../packages/bash/bash) → [dsh-bash-local](../../../../packages/bash/bash-local)），具备进程组终止、输出截断/溢出处理和凭证擦除功能。复用它来执行钩子意味着钩子桥接层无需重新实现子进程管道——但该 seam 此前无法写入 stdin 或设置额外 env。本 Agent Note 添加这两个输入。
+
+`stdin` 和 `env` 不构成新的模型能力，因为普通 shell 语法已经能提供两者。环境凭证由 `dsh-bash-local` 的子环境擦除机制保护，而非靠隐藏这些 seam 字段；模型工具参数是静态 JSON，不会展开 shell 变量。因此这些字段服务于受信的进程内调用方（如钩子桥接层），它们需要传递结构化输入和 `CLAUDE_*` 变量，而不必将其嵌入模型可见的 shell 文本。环境变量规则见 [defensive-patterns.md](../../../../docs/defensive-patterns.md)。
+
+## 决策
+
+在 `BashExecRequest`（模型/插件侧请求）和 `BashExecSpec`（`run`/`start` 所作用的已解析 spec）上**同时**添加 `stdin?: string` 与 `env?: Record<string, string>`，并在 `dsh-bash-local` 中贯穿它们：`resolve()` 原样传递，`run()`/`start()` 将其传给 `runBash`，后者把字节写入子进程的 stdin 并合并额外 env。
+
+三个有意为之的选择：
+
+1. **模型侧工具不暴露 `stdin` 和 `env`。** Shell 语法已覆盖这些需求，重复参数只会增加接口面而不带来权限隔离。工具仅从声明的模型参数、signal 和 owner 构建请求；受信的进程内调用方可以直接设置 seam 字段。harness 自有变量使用[托管环境决策](../feature/2026-07-10-agent-session-identity-and-log-location.md)规定的独立 `dshEnv` 通道，因此普通 `env` 无法替换它们。
+
+2. **`env` 在凭证擦除之后合并，因此调用方显式设置的条目即使具有凭证形态的名称也会胜出。** 后续的托管命名空间决策保留 `DSH_*`：环境条目会被移除，普通 `env` 无法设置它们，受信的 `dshEnv` 最后合并。完整顺序为 `scrub(process.env, including DSH_*)` → `ENV_OVERRIDES` → 普通 `env` → `dshEnv`。
+
+3. **`stdin`/`env` 在已解析 spec 上是 required-absent-OK（普通 optional），而非像 `owner` 那样 required-but-nullable。** `owner` 之所以是 required-but-nullable，是因为*静默*缺失的 owner 会产生一个无主、跨会话可读的任务——一个安全隐患，显式的 `undefined` 可以防范。`stdin`/`env` 没有这种风险：缺失意味着「无 stdin / 无额外 env」，这是安全的常规情况（所有模型驱动的调用都如此）。因此它们保持普通 optional，与 `signal` 一致。
+
+`dsh-bash-local` 仅在有字节需要写入时才创建 stdin 管道；否则 fd 0 仍为 `/dev/null`，保持先前行为。它写入字节后关闭管道。子进程未读取即退出时产生的 `EPIPE` 被忽略，因为命令退出码和输出决定结果。
+
+## 曾考虑的替代方案
+
+**可配置的环境秘密擦除。** 否决，属于推测性需求。受信调用方可以在擦除之后显式提供所需值，无需削弱默认的环境保护。
+
+## 后果
+
+钩子桥接层通过既有的 bash seam 传递 JSON 载荷和钩子特定变量，保留其进程组终止、截断和溢出行为。模型接口面不变，bash 工具仍是模型调用请求构建的唯一所有者。相关词汇定义见 [bash 数据结构参考](../../../../docs/core-data-structures/bash.md)。

## Problem
The harness extends the agent loop through a Cordis event taxonomy (see [the microkernel event-taxonomy Agent Note](2026-06-11-microkernel-event-taxonomy.md)). As that taxonomy grew, the line between the three event domains blurred:

+# Agent Note: 事件域语义——会话是事实日志，agent 是运行时表面
+
+Status: implemented
+
+[English](2026-06-30-event-domain-semantics.md) | 中文
+
+## 问题
+
+harness 通过 Cordis 事件分类体系扩展 agent loop（智能体循环）（见[微内核事件分类体系 Agent Note](2026-06-11-microkernel-event-taxonomy.md)）。随着该分类体系的增长，三个事件域之间的界限变得模糊：
+
+- `session/*` 承载持久的、事件溯源的日志（`SessionEventMap`）。
+- `agent/*` 承载运行时实时信号，向插件传递 `Agent` 句柄。
+- `tools/*` 承载工具注册表与执行 seam。
+
+两个问题促使我们固定语义。第一，若干轮次/步骤边界同时作为持久的 `SessionEvent`（`turn/start`、`turn/end`、`step/start`、`step/end`）和镜像的 `agent/*` emit（`agent/turn-start`、`agent/turn-end`、`agent/step-start`、`agent/step-end`）存在。消费方对同一事实有两个真源，每次生命周期变更都必须同时更新两处。第二，即将到来的钩子子系统需要一个连贯且有文档的订阅表面——插件作者（以及基于其上构建的 Claude Code / Codex 钩子桥接）必须在不阅读循环代码的情况下知道应该监听会话事件还是 agent 事件，以及原因。
+
+这套词汇是拦截决策、持久的 `hook/*` 日志，以及 Claude Code 和 Codex 桥接的基础。
+
+## 决策
+
+**三个域，各司其职，以一条边界规则统一。**
+
+- **`session/*`——持久的、可回放的事实日志。** 拥有 `SessionEventMap`；每条记录仅含 JSON（无活对象）。每次追加触发一次 `session/event` emit，加上 `session/flush` 并行持久性检查点。它同时也是实时 transcript（文本记录）源：想渲染或响应已发生事件的消费方在此订阅，因此实时渲染与回放投影共享同一路径。
+- **`agent/*`——运行时实时表面。** 始终携带活的 `Agent`。两种形态：拦截 waterfall（瀑布式事件）（`agent/request`、`agent/step-result`、`agent/turn-continuation`）可变更或否决；瞬态 emit（`agent/status`、`agent/error`、`agent/created`/`agent/disposed`、`agent/queued`）在持有 `Agent` 的情况下通知。轮次和步骤边界不在此处——它们是持久的会话事件，从 `session/event` 读取；token 流（`assistant/chunk`）和中途 steering（中途引导）（`steering/message`）同理。
+- **`tools/*`——工具注册表与执行 seam。**
+
+**边界规则：** 持久的、可回放的事实是 `SessionEvent`；实时拦截或瞬态/活对象信号是 `agent`/`tools` Cordis 事件。轮次或步骤边界是持久事实，因此存在于会话日志中并从 `session/event` 源读取——不会被镜像为 `agent/*` emit。
+
+**将规则应用于边界镜像：** 全部四个边界镜像——`agent/turn-start`、`agent/turn-end`、`agent/step-start`、`agent/step-end`——被**移除**。没有生产消费方需要在边界处获取活的 `Agent`：ACP 桥接将其进行中的提示词与精确对应的 `session/event` `turn/start`/`turn/end` 事件对关联，其他 transcript 消费方同样从持久流派生边界。见[移除边界镜像事件 Agent Note](../simplification/2026-06-20-remove-agent-boundary-mirror-events.md)，该决策由它负责。移除 emit 也简化了循环的 `closeStep`/`closeTurn`（各只需一次 append，无需配对 emit）。
+
+## 后果
+
+- 循环不再 emit 任何边界镜像；`closeStep` 仅追加 `step/end`，`closeTurn` 仅追加 `turn/end`。`Session.append` 负责 post-commit observer 隔离，因此抛出异常的边界 observer 无法改变轮次结果或饿死后续消费方；接受或内部校验失败仍会在边界进入日志之前逃逸。

+# Agent Note: 相对文件系统路径按调用方的会话 cwd 解析
+
+Status: implemented
+
+[English](2026-07-02-fs-per-session-cwd.md) | 中文
+
+## 问题
+
+ACP（Agent Client Protocol）桥接层为每个会话提供独立的工作区：`session/new` 将自动化客户端的项目目录记录为 `SessionHeader.cwd`，`dsh-tool-bash` 将每次 bash 调用的 `workdir` 默认设为调用方 agent（智能体）的 `session.header.cwd`（见 [ACP 包](../../../../packages/acp/acp)与 `dsh-tool-bash` 中的 `resolveWorkdir`）。因此会话 A 中的 bash 命令在 A 的项目目录执行，会话 B 中的在 B 的项目目录执行——一个服务器进程，N 个工作区。
+
+文件系统解析使用的是插件加载时的 cwd，而 bash 使用的是会话的项目目录。因此，当自动化客户端的项目目录与服务器启动目录不同时，相对路径的解析结果就会不一致；快照测试因为让这两个路径相同而掩盖了这个 bug。
+
+一个有效的绝对 cwd 本身可能看起来有两个父目录：当它包含 `symlink/..` 时，文件系统查找会先跟随符号链接再应用 `..`，而 `path.resolve()` 会从词法上抹掉这两个组件。如果用词法解析沙箱策略却从原始 cwd 启动 bash，就会把权限授予无关的词法父目录、拒绝真实工作区内的写入，并让文件系统工具把相对路径解析进错误目录。
+
+普通的符号链接 cwd 在请求的相对路径包含 `..` 时也暴露同一区别：进程从符号链接的物理目标开始遍历，`path.resolve(cwd, path)` 却从其词法拼写开始遍历。因此，对于同一个模型提供的路径，read 会选择与 bash 或沙箱化 mutation 不同的文件。
+
+## 决策
+
+将调用方的会话 cwd 传入路径解析，与 `dsh-tool-bash` 对 `workdir` 的处理方式完全一致。当 cwd 或请求路径任一包含父目录段时，在任何词法 join 之前把 cwd 解析为原生文件系统标识；没有遍历会使标识可观察时，则保留普通 cwd 拼写以供展示。mutation 和沙箱化 bash 调用复用解析后的沙箱策略根目录，使一次调用只有一个工作区标识。**调用方**（即工具）提供 cwd；提供方不读取会话或 agent。
+
+- `FileSystem.resolve` 接受 `resolve(path: string, opts?: { cwd?: string; signal?: AbortSignal }): Promise<FsTarget>`。`opts.cwd` 是相对 `path` 解析时的基准目录；绝对 `path` 忽略它；省略 `opts.cwd` 则使用后端自身的默认值。后端执行 I/O 时，`opts.signal` 可以取消解析。options 对象把调用方拥有的两个解析控制项放在一起，避免位置参数继续增长。
+- `dsh-fs-local.resolve` 使用 `resolveLocalTarget(opts?.cwd ?? this.config.cwd, path)`。`config.cwd` 仍作为调用方未提供会话 cwd 时的默认值。
+- `dsh-tool-fs` 的 `read`/`write`/`edit` 通过共享的 `sessionCwd(exec, requestedPath)` 辅助函数（`exec.agent?.session.header.cwd`，与 bash 的 `resolveWorkdir` 对应）获取会话 cwd，并传给 `resolve`。只要任一值中的父目录段可能跨越符号链接，该辅助函数就使用原生 realpath 语义，否则保留普通拼写；沙箱化 mutation 复用完整策略的 `workspaceRoot`；非 agent／无 header 的调用方得到 `undefined`，后端因此应用其默认值。
+
+## 曾考虑的替代方案
+
+### 为何由调用方（而非提供方）提供 cwd
+
+提供方 seam 不得依赖 `dsh-agent`／`dsh-session`——它是一个文本存储后端，沙箱或远程实现同样满足该接口，而这些实现没有「agent 会话」的概念。工具已经接收了 `ToolExecution`（`exec`），其中携带 agent，因此工具是将 `exec → cwd` 投影并向提供方传递一个纯字符串的正确位置。这遵循「包（package）边界处显式优于隐式」的约定：基准目录作为显式参数传入，提供方据此行动，而非让提供方越界去读取它不应知晓的会话。这也与 `dsh-tool-bash` 一一对应，使两个面向模型的文件操作接口以相同方式解析路径。
+
+默认值只存在于一个地方——提供方的 `config.cwd`。`sessionCwd` 在没有会话时返回 `undefined` 而非 `process.cwd()`，因此工具永远不会自行制造一个提供方本应自行选择的基准目录。
+
+## 后果
+
+- 在 ACP 演示中，fs 工具与 bash 对每个会话的工作区达成一致；自动化客户端可以选择任意绝对项目目录，两类工具都在该目录下操作。
+- 对于包含 `symlink/..` 的会话 cwd，或普通符号链接 cwd 搭配含父目录遍历的相对路径，bash、文件系统工具和沙箱授权都会从同一个物理工作区解析；词法父目录不会获得授权。
+- `FsTarget` 的标识不变：`targetKey` 仍为解析后绝对路径的 realpath，因此 observed-state 键控与符号链接标识不受影响——正确的每会话 cwd 产生与 bash 目标相同的 key。
+- 向后兼容：所有现有的 `resolve(path)` 调用（均在测试中）继续正常工作；新参数是可选的。
+- 单会话 stdio 演示不受影响：它不提供会话 cwd（其 agent 的会话没有 `cwd`），因此解析回退到 `config.cwd = process.cwd()`，即工作区本身。

+# Agent Note: 结果时刻的 applied-hunk diff 用于文件变更

+
+## 问题
+
+[带标签的 render-intent 联合类型](2026-07-02-tool-render-intent-union.md)为 `dsh-tool-fs` 的 write/edit 在调用时刻提供 `card:'diff'`，纯粹从工具参数推导：write ⇒ `{oldText:null, newText:content}`（整个新文件），edit ⇒ `{oldText:old_string, newText:new_string}`（裸替换片段）。UI 可以将其渲染为行内 diff，但这是一个**无上下文**的 diff：裸的 `old_string`→`new_string` 没有周围行，而一次触及五个分散位置的 `replace_all` 仍然渲染为一对片段。
+
+在对接 `claude-agent-acp` 自身的 ACP（Agent Client Protocol） bridge 时可以看到完整编辑器 diff 的样子：变更应用后，它发出第二个 `tool_call_update`，其 diff 是**带 ±3 行上下文的 applied hunk**（`replace_all` 的每个变更位置各一个 hunk），由工具的 `structuredPatch` 重建。这个结果时刻的 hunk 正是让 Zed 在文件中*原位*显示变更（而非浮动片段）的关键。我们的工具止步于调用时刻的片段；完成后的结果只携带纯文本「updated successfully」，没有 diff。
+
+障碍在于一个 seam 边界：`presentResult(args, result)` 是 **`args` + 面向模型的 `result`（`{content, isError}`）的纯函数**——它在实时流式输出和会话日志回放中都会运行，因此必须具备回放确定性且不能做 I/O。它看不到文件的前后内容，而 `FsEditOutcome`/`FsWriteOutcome` 只携带替换计数和版本号，没有文本。因此无法计算——甚至无法携带——applied hunk 给 presenter。
+
+## 决策
+
+添加一个**持久化的、工具私有的展示通道**，使工具的 `execute` 能附加一个结果时刻的渲染载荷并在回放中存活，并用它来携带 applied-hunk diff。
+
+### 1. 规范工具输出上的可回放展示投影（core）
+
+原始实现允许 `execute` 返回 `{ content, meta }`。[规范工具输出契约](2026-07-20-canonical-tool-output-contract.md)取代了这种编写形态：每个工具如今返回一个由 schema 声明的 JSON 值，`output.render(args, value)` 从中派生面向模型的内容块，可选的 `output.presentationMeta(args, value)` 则派生可回放的 UI 数据。
+
+`presentationMeta` 是工具自有的 `JsonValue`，core 会持久化它，但不解释其中的字段。`Session.append` 将它与事件的其余部分一并校验，回放再把存储的载荷传回 `presentResult`；因此展示无需 I/O 或重新计算即可复现。规范值本身只存在于执行期间，不会加入会话格式。
+
+这仍是通用形态（「工具投影持久化的结果展示」），而非 fs 特有；任何工具都可以使用。
+
+### 2. 工具计算 hunk；后端返回 before/after（fs）
+
+按照 [capability-seam 拆分](2026-06-13-capability-seams.md)，存储后端只返回**存储事实**，面向模型的工具拥有**展示**：
+
+- `dsh-fs` 将 `FsEditOutcome` 扩展为包含 `{ before: string; after: string }`，将 `FsWriteOutcome` 扩展为包含 `{ before: string | null; after: string }`（`before: null` 表示创建，或已存在但不可 diff 的二进制/非 UTF-8 文件）。本地后端在写入时已持有两份文本；它以原始 LF 规范化文本返回，**不让任何 diff/UI 概念进入 seam**。
+- `dsh-tool-fs` 返回规范的变更前／后事实，并将上下文 hunk 投影为 `meta: { diffs: FileDiff[] }`。成功的变更以 diff 视图完成：创建或无变化的覆写回退到由参数推导的整文件 diff，而编辑使用 applied hunk。失败的变更不携带 diff 元数据，正常渲染其错误信息。
+
+### 3. UI 传输层渲染 `diff` 结果视图
+
+`ToolResultView` 包含 `DiffResultView { card:'diff'; title?; diffs: FileDiff[] }`。TUI 与 JSON-RPC/Web 消费方在同一个带标签的视图上做 switch，用 applied 结果 hunk 替换待定调用的无上下文片段。[仅面向自动化的 ACP 桥接层](../simplification/2026-07-23-acp-automation-only-protocol.md)不承载工具展示。
+
+## 曾考虑的替代方案
+
+**手写或 vendor diff 算法。** 上下文 hunk 有已知的边界情况，因此 `dsh-tool-fs` 使用带类型的 [`diff`](https://www.npmjs.com/package/diff) 包，并在一个模块中规范化 `structuredPatch` 输出。仓库的 vendor 策略适用于框架源码，而非每个叶子工具库。
+
+## 后果
+
+`tool/result` 事件携带工具私有的 `meta` 载荷；它属于磁盘格式词汇的一部分，由 `Session.append` 在运行时限制为 JSON。任何工具都可以投影持久化的结果展示，无需再改 core。diff 卡片在会话重载和快照回放时免费复现：它从日志中读回，从不重新计算。代价：覆写操作在内存中同时持有旧文本和新文本以计算仅用于 UI 的 hunk（`TODO(overwrite-diff-bound)`），且 `dsh-tool-fs` 引入了一个小型、知名的运行时依赖。
+
+## 非目标
+
+- **实时增量 diff 流式输出。** hunk 在变更完成后一次性计算；没有逐键 diff。
+- **对二进制/非 UTF-8 覆写做 diff。** 此类文件的 `before` 为 `null`（没有文本 diff 基础）；写入仍然成功，结果渲染整文件 diff（`oldText: null`）而非上下文 hunk。
+- **重命名/移动 diff。** 仅限单个已解析路径的内容 diff。
+- **限制覆写 diff 基础的大小。** 覆写操作将整个旧文件读入内存以计算上下文 hunk（加上已持有的新内容），因此非常大的文本覆写会为仅 UI 用途的 diff 分配两份文本。未来的改进可以设定预读上限，超过阈值时回退到整文件/无上下文 diff；在读取位置以 `TODO(overwrite-diff-bound)` 跟踪。
+
+## 相关

+- 补全了[带标签的 render-intent 联合类型](2026-07-02-tool-render-intent-union.md)中作为非目标列出的最后一项表示差异——该 Agent Note 的「非目标」一节已更新，记录 applied-hunk diff 在此处交付。
+- 基于[文件系统 capability seam](2026-06-17-filesystem-capability-seam.md)（before/after 是后端返回的存储事实）和[事件溯源会话](2026-06-11-event-sourced-sessions.md)（`meta` 载荷持久化在 `tool/result` 事件上，因此回放可复现卡片）。
+- `meta` 通道有意设计为通用的：未来的工具（结构化搜索、数据表结果）可以附加自己的持久化结果展示而无需再改 core。

## Problem
A tool declares how its calls render in a UI (an editor's tool-call card) through two callbacks, `presentCall`/`presentResult` on `ToolDefinition`, returning `ToolCallPresentation` / `ToolResultPresentation` with an optional `ToolTerminal` sub-shape. These grew incrementally into a **bag of optional fields**: `title`, `kind`, `rawInput`, `content`, `locations`, `terminal` on the call; `title`, `content`, `terminal` on the result; `cwd`/`output`/`exitCode`/`signal` on `ToolTerminal`. The split of responsibility is muddy:

- Which combinations are *valid* is unwritten: a `terminal` call that also sets `content` means "description above the card"; a generic call that sets `terminal` is meaningless but representable. The type permits nonsense.

### Why a tagged union beats the field-bag
- **Invalid states become unrepresentable.** A generic card cannot carry terminal output; a terminal card cannot carry a diff. The old bag permitted all of these.
-- **The bridge switches instead of stitching.** One arm per card kind, each producing exactly the wire shape that card needs, rather than reconciling five optional fields whose interactions are undocumented.
-- **`diff` is a first-class intent.** `dsh-tool-fs` write/edit declare `card:'diff'`; the bridge emits an ACP `{type:'diff', path, oldText, newText}` `ToolCallContent` (already in the SDK's `ToolCallContent` union, previously unused by the bridge). This is the affordance the redesign unlocks.

`TerminalResultView` carries only `output`/`exitCode`/`signal`. A UI without the terminal capability needs a fenced ` ```console ` text fallback; that derivation moves to the **bridge** (it wraps `output` in a fenced block on the no-capability path), rather than the tool double-encoding it. This keeps the bash tool's result a single structured shape and preserves the existing capability-gated behavior byte-for-byte.
+The terminal intent is display-only. The harness still executes the command through its bash service, preserving sandboxing, environment scrubbing, task ownership, and per-session cwd; a UI projects the completed call and never becomes a second execution backend.
+
### Purity preserved
`presentCall`/`presentResult` remain pure functions of `args` (+ the result for `presentResult`) — they run on live streaming AND session-log replay, so they must be replay-deterministic. Every view is derived from args alone: write's diff is new-file style (`oldText:null`) because the tool has no old content at call time; edit's diff is `old_string`→`new_string`.
-## Relative-path display titles
-
-`claude-agent-acp` relativizes a file card's title path against the session cwd (`toDisplayPath`) — `Read src/foo.ts`, not `/abs/proj/src/foo.ts` — while keeping `locations[]`/`diff.path` **raw** (the editor opens the real path). Our `presentCall` is pure/args-only and cannot see the session cwd, so this relativization happens at the **bridge**, which already threads the session cwd into tool-call rendering (the same cwd it uses to resolve a terminal card's header). The bridge relativizes the title only, by an exact structured replace of the known `locations[0].path`/`diffs[0].path` substring — generic over the file-card kinds, never special-casing tool names.

## Alternatives considered
- **Delete tool-owned presentation entirely** — [the rejected collapse proposal](../../rejected/simplification/2026-06-20-generic-tool-rendering.md); its own verdict deferred to exactly this union once two real tools and two real consumers existed, and that bar is now met.
+- **Let a UI execute terminal intents** — rejected because it would bypass the harness's bash policy and ownership contracts and fork command execution across backends. A terminal card describes harness-owned execution; it never authorizes client-side execution.
- **A merge-extensible union** (the `ContentBlockMap` pattern) — rejected: a new render intent needs new bridge code to render it anyway, so a plugin-added variant the bridge silently drops would be worse than the compile error the closed union raises at the bridge's `assertNever` switch.
- **Keeping the optional-field bag** — the status quo the Problem dissects: invalid states representable, undocumented field interactions, and no way to ask for a diff card at all.

+# Agent Note: 用于工具调用展示的带标签 render-intent 联合类型
+
+Status: implemented
+
+[English](2026-07-02-tool-render-intent-union.md) | 中文
+
+> render-intent 联合类型对 UI 传输层仍然有效；其 ACP 映射已被 [ACP 作为仅面向自动化的协议](../simplification/2026-07-23-acp-automation-only-protocol.md)取代。
+
+## 问题
+
+工具通过 `ToolDefinition` 上的两个回调 `presentCall`/`presentResult` 声明其调用在 UI（编辑器的工具调用卡片）中如何渲染，返回 `ToolCallPresentation` / `ToolResultPresentation`，并带有一个可选的 `ToolTerminal` 子结构。这些类型在增量演进中变成了一个**可选字段的集合**：调用侧有 `title`、`kind`、`rawInput`、`content`、`locations`、`terminal`；结果侧有 `title`、`content`、`terminal`；`ToolTerminal` 上有 `cwd`/`output`/`exitCode`/`signal`。职责划分模糊不清：
+
+- 调用侧和结果侧的 `terminal` 字段重叠，bridge 需要将每次调用的 `content` 块、`terminal` 块和 `rawInput` 用临时条件逻辑拼接在一起。
+- 哪些组合是*合法的*没有文档说明：一个设置了 `content` 的 `terminal` 调用意味着「卡片上方的描述」；一个设置了 `terminal` 的 generic 调用毫无意义但类型上可表达。类型允许无意义的状态存在。
+- 无法表达编辑器最需要的文件工具能力：**diff 卡片**（`{path, oldText, newText}`，Zed 将其渲染为内联 diff / 新文件预览）。`ToolCallPresentation.content` 使用的是 *LLM（大语言模型）* 的 `ContentBlock[]` 词汇（text/image），工具根本无法请求 diff 展示。
+
+`packages/core/tools/src/index.ts` 中已有的 `FIXME(tool-presentation)` 指出了修复方向：「重新设计类型，让工具一次性声明其渲染意图（例如按卡片种类的带标签联合类型），而非一堆由 bridge 拼接的可选字段。」被否决的 Agent Note [折叠工具拥有的 UI 呈现](../../rejected/simplification/2026-06-20-generic-tool-rendering.md)明确推迟了此事：富渲染「应当在至少有两个真实工具和两个真实消费方验证词汇之后，以带标签 render-intent 联合类型的形式回归。」该条件已由多个生产者族，加上 TUI 与宿主/客户端运行时（Web）这些消费方满足。
+
+## 决策
+
+用一个**以 `card` 为标签的可辨识联合类型**替代可选字段集合。工具为每次调用/结果声明一个渲染意图；bridge 根据标签分发。
+
+```ts ignore-check
+type FileLocation = { path: string; line?: number }
+type FileDiff = { path: string; oldText: string | null; newText: string } // oldText null ⇒ new file
+
+// presentCall → ToolCallView
+type ToolCallView = GenericCallView | TerminalCallView | DiffCallView
+interface GenericCallView { card: 'generic'; title: string; kind?: ToolCallKind; rawInput?: unknown; content?: ContentBlock[]; locations?: FileLocation[] }
+interface TerminalCallView { card: 'terminal'; title: string; description?: string; cwd?: string }
+interface DiffCallView { card: 'diff'; title: string; diffs: FileDiff[]; locations?: FileLocation[] }
+
+// presentResult → ToolResultView
+type ToolResultView = GenericResultView | TerminalResultView
+interface GenericResultView { card: 'generic'; title?: string; content?: ContentBlock[] }
+interface TerminalResultView { card: 'terminal'; title?: string; output?: string; exitCode?: number; signal?: string }
+```
+
+`card` 在每个变体上都是**必填**的——真正的判别式，而非可选默认值。bridge 执行 `switch (view.card) { case 'generic': … case 'terminal': … case 'diff': … default: assertNever(view) }`。该联合类型是**封闭的**（遵循 [switch 穷举约定](../../../../AGENTS.md)）：第四种渲染意图（表格、图表）无论如何需要新的 bridge 代码来渲染，因此一个由插件添加但被 bridge 静默丢弃的变体，比编译错误更糟糕。新增变体会在 bridge 的 switch 处中断编译——这正是我们想要的信号。
+
+### 为什么带标签联合类型优于字段集合
+
+- **无效状态变得不可表达。** generic 卡片不能携带终端输出；terminal 卡片不能携带 diff。旧的字段集合允许所有这些组合。
+- **消费方分发而非拼接。** 每种卡片一个分支，精确产出该卡片所需的视图，而非调和五个交互关系未文档化的可选字段。
+- **`diff` 成为一等意图。** `dsh-tool-fs` 的 write/edit 声明带 `{path, oldText, newText}` 的 `card:'diff'`，让有能力的 UI 无需针对工具名做特殊处理即可渲染行内变更。
+
+### 生产者映射
+
+- `dsh-tool-fs` read → `generic`（`kind:'read'`，附带一个 follow-along `location`）；write → `diff`（`oldText:null`）；edit → `diff`（`oldText:old_string || null`，`newText:new_string ?? ''`）。这与 `claude-agent-acp` 的 `toolInfoFromToolUse` 中 Read/Write/Edit 各分支逐字段对应。
+- `dsh-tool-bash` foreground → `terminal` 调用 + `terminal` 结果；`run_in_background` → `generic`。通用 `task_*` 控制工具拥有各自的 generic 卡片。
+- `dsh-tool-todo` → `generic`。
+
+### 终端回退的归属
+
+`TerminalResultView` 只携带 `output`/`exitCode`/`signal`。不具备终端能力的 UI 需要一个围栏 ` ```console ` 文本回退；该推导移至 **bridge**（在无能力路径上将 `output` 包裹在围栏代码块中），而非由工具双重编码。这使 bash 工具的结果保持单一结构化形状，并逐字节保留既有的能力门控行为。
+
+terminal 意图只用于展示。harness 仍通过自身的 bash 服务执行命令，从而保留沙箱、环境清理、任务归属和每会话 cwd；UI 只呈现已完成的调用，绝不会成为第二个执行后端。
+
+### 纯函数性保持不变
+
+`presentCall`/`presentResult` 仍然是 `args`（`presentResult` 还有 result）的纯函数——它们在实时流式输出和会话日志回放中都会运行，因此必须具备回放确定性。每个 view 仅从 args 推导：write 的 diff 是新文件风格（`oldText:null`），因为工具在调用时没有旧内容；edit 的 diff 是 `old_string`→`new_string`。
+
+## 曾考虑的替代方案
+
+- **完全删除工具自有的展示**：即[被否决的 collapse 提案](../../rejected/simplification/2026-06-20-generic-tool-rendering.md)；其自身的结论正是推迟到两个真实工具和两个真实消费方存在后再做此联合类型，该条件现已满足。
+- **让 UI 执行 terminal 意图**：否决。这样会绕过 harness 的 bash 策略与归属契约，并把命令执行分裂到不同后端。terminal 卡片描述的是 harness 拥有的执行，绝不授权客户端侧执行。
+- **可合并扩展的联合类型**（`ContentBlockMap` 模式）：否决。新的渲染意图无论如何需要新的 bridge 代码来渲染，因此一个被 bridge 静默丢弃的插件添加变体，比封闭联合类型在 bridge 的 `assertNever` switch 处引发的编译错误更糟糕。
+- **保留可选字段集合**：即「问题」一节所剖析的现状：无效状态可表达、字段交互无文档、且完全无法请求 diff 卡片。
+
+## 后果
+
+新的渲染意图会在 bridge 的 switch 处引发编译中断——这是有意为之：渲染代码必须先于卡片种类存在。无效的卡片/字段组合现已不可表达，bash 回退推导归 bridge 所有，工具只返回一个结构化形状。第四种卡片（表格、图表）的门槛是在同一个变更中编写其 bridge 分支。
+
+## 非目标
+
+- **实时增量 `terminal_output_delta` 流式输出**与**命令分类**：终端渲染 Agent Note 自身推迟的后续工作，本 Agent Note 不涉及。
+
+## 相关
+
+- 取代[折叠工具拥有的 UI 呈现](../../rejected/simplification/2026-06-20-generic-tool-rendering.md)（已否决——「等两个真实工具和两个真实消费方，然后做带标签 render-intent 联合类型」）中的推迟决定。该条件现已满足；本 Agent Note 即为那个联合类型。
+- 被[结果时已应用 hunk 差异](2026-07-02-result-time-applied-hunk-diffs.md)扩展：后者添加了一个持久化的 `meta` 通道，使 write/edit 在结果时输出 `DiffResultView`（应用后的变更：带上下文行的 contextual hunk / 每个 `replace_all` 位点一个，或创建时的整文件 diff），叠加在本联合类型的调用时 diff 卡片之上。
+- 将 `ToolTerminal` 折入当前 UI 传输层使用的带标签 `terminal` 视图。

## Problem
`@deepseek-ai/dsh-fs` is the provider seam for filesystem access, with local and future non-local backends behind the same `ctx.fs` contract. Before this change it could resolve paths, stat targets, read text, stream text, write text, and edit text. That was enough for model-facing file tools, but not for non-model-facing consumers that need to enumerate directories without importing `node:fs`.

+# Agent Note: 为文件系统 seam 添加直接目录列举能力
+
+Status: implemented
+
+[English](2026-07-03-filesystem-directory-listing-seam.md) | 中文
+
+## 问题
+
+`@deepseek-ai/dsh-fs` 是文件系统访问的提供方 seam，本地后端与未来的非本地后端共享同一个 `ctx.fs` 契约。在本次变更之前，它能解析路径、stat 目标、读取文本、流式读取文本、写入文本和编辑文本。这对面向模型的文件工具已经足够，但对于需要枚举目录而又不想直接导入 `node:fs` 的非模型侧消费方来说还不够。
+
+直接的压力来自 skill（技能）加载：读取单个 `SKILL.md` 已经可以走 `ctx.get('fs')`，但发现哪些 skill 根目录包含 `<name>/SKILL.md` 或 `<name>.md` 仍需要目录枚举。如果仅在 `dsh-skill` 中添加目录列举，要么保留对 Node 的直接依赖，要么在文件系统提供方栈之外发明一个一次性的本地辅助函数。
+
+本决策只添加提供方能力，不涉及面向模型的 `ls`/`list` 工具或 skill 发现机制的变更。那些消费方需要独立的 UX、提示词与策略决策。
+
+## 决策
+
+在 `@deepseek-ai/dsh-fs` 中添加 `FileSystem.listDir(target, signal?)`。
+
+`listDir` 仅列举一层目录。它以稳定的名称顺序返回直接子项，包含以下字段：
+
+- `name`：子项的 basename；
+- `type`：`file`、`directory` 或 `other`；
+- `target`：已解析的子项 `FsTarget`；
+- `version`：可用时返回的轻量元数据；
+- `size`：可用时返回的常规文件大小。
+
+它从不读取文件内容。递归遍历、glob 匹配、分页、搜索、文件监听和面向模型的渲染均有意不在范围内。
+
+本地后端通过 `readdir({ withFileTypes: true })`、`resolveLocalTarget` 以及元数据 `stat`/`realpath` 探测来实现。结果顺序是确定性的（`name.localeCompare`），以保持未来消费方的提示词/列表输出稳定，并提高前缀缓存复用率。
+
+损坏或已消失的子项可以表示为 `type: 'other'`（不带 `version`/`size`）；它们不会中止整个列举。在列举目录或解析/探测子项元数据时遇到权限或后端 I/O 故障，则以结构化的 `FsError` 错误码使整个列举失败：
+
+- `FS_NOT_FOUND`：目标不存在；
+- `FS_NOT_DIRECTORY`：目标存在但不是目录；
+- `FS_PERMISSION_DENIED`：权限不足；
+- `FS_IO_ERROR`：其他后端 I/O 故障；
+- `FS_ABORTED`：调用被中止。
+
+## 曾考虑的替代方案
+
+**在添加 seam 的同时添加面向模型的 list 工具。** 否决。其提示词、schema 和渲染契约与提供方原语相互独立。
+
+**让每个消费方自行枚举目录。** 否决。这会将 `dsh-skill` 等产品包绑定到 Node/本地文件系统行为上，绕过策略/远程/沙箱后端。
+
+**让 `listDir` 支持递归或 glob 形式。** 暂时否决。skill 根发现只需要直接子项，而简单的单层列举是未来消费方可以安全组合的最小后端契约。
+
+**跳过元数据解析失败的子项。** 否决。API 承诺返回已解析的子项 target，因此解析子项时的权限/IO 故障属于契约失败。损坏或已消失的子项是例外，因为它们仍可在不声称拥有一个活跃已解析文件的前提下被表示。
+
+## 后果
+
+每个文件系统后端现在必须多实现一个提供方原语。这是 harness 尚未发布时有意为之的基础工作，但也意味着未来的沙箱/远程后端需要定义等价的直接子项列举行为。
+
+该能力仍停留在提供方层面。在消费方落地之前，ACP（Agent Client Protocol）/模型会话仍需使用 `bash` 等既有工具来列举目录。缺少面向模型的 `listdir` 工具是预期行为，而非接线错误。

+# Agent Note: 提示词变量与工具指导归属

+Status: implemented

+[English](2026-07-05-prompt-variables-and-tool-guidance-ownership.md) | 中文
+
+## 问题
+
+组装后的系统提示词存在四个缺陷，同属一类：harness 已知的事实在别处被手工重述，然后漂移。
+
+**模型无法知道自己的名字。** `AgentOptions.model` 驱动每个请求，但没有任何提示词文本携带它——也不可能携带：`dsh-system-prompt` 中的 section 是上下文全局的，而模型名称是 per-agent 的，`assemble()` 根本不接受任何 per-agent 输入。
+
+**工具指导是 leaf YAML 中的手写行文。** bash/subagent/todo_write 的使用指导存放在 coding-agent 和 ACP persona 字符串里——两份漂移的副本（ACP 那份已经被删减）——而 `dsh-tool-fs` 和 `dsh-tool-web` 则通过 `ctx.systemPrompt.section()` 贡献各自的指导。加载或卸载一个工具插件意味着手动编辑每个部署的 persona；两份 YAML 都带着一条 `FIXME(config-comments)` 为这种分裂的症状道歉，旧终端欢迎横幅也手动枚举了工具集。
+
+**Persona 渲染在工具指导之后。** agent loop（智能体循环）将 `agent.options.systemPrompt` 字符串拼接在已组装的 section 之后，于是模型先读到「Use the read tool…」再读到「You are a coding agent」——与 identity-first 约定（Claude Code、Codex）相反，且是 section 流水线之外的第二条组合路径。
+
+**Fork 工具的描述是假的。** `dsh-tool-subagent` 硬编码了一段为 spawn 语义编写的描述——「a separate agent that works in its own context … it does not see this conversation」——而 `subagent_fork` 实例（其子 agent 继承父级已完成的轮次）拿到了同样的措辞；YAML 行文在带外纠正了这个谎言。小问题：`PromptSection.name` 文档标注为「(diagnostics / dedup)」，但重复项被静默接受。
+
+## 决策
+
+**一条原则：提示词中的每个事实恰好有一个归属方。** 模型名称和工作区是配置/会话事实 → harness 将它们暴露为变量，persona 引用它们。每个工具的语义和何时使用 → 工具的 `description`。description 无法承载的跨调用习惯 → 工具包（package）的提示词 section。harness 来源标识 → 静态的 `harness:identity` section。部署角色与行为 → 部署的 persona。

+`SystemPrompt.assemble(context)` 接受一个可合并扩展的 `AssembleContext`。`dsh-system-prompt` 声明可选的 `scope` 选择器用于 scoped 路由，而 `dsh-agent` 通过声明合并将可选的类型化 `agent` 字段附加到其上（类型层面的 `agent → system-prompt` 边，无运行时依赖循环）。循环在每个步骤调用 `assembleContextFor(agent)`，使两个字段标识同一个 agent；section 文本提供方可以读取该上下文，`system-prompt/assemble` waterfall（瀑布式事件）也接收它，监听器可据此按 agent 过滤或扩展。
+
+### 提示词变量
+
+插件通过 `ctx.systemPrompt.variable(name, provider)` 注册 `{{name}}` 值。组装过程将它们解析到 waterfall 可见的变量映射中。渲染阶段拒绝以下情况：引用了未知的 own-property、已注册的提供方返回 `undefined`、格式错误的完整引用、以及仍包含闭合 `}}` 的不平衡引用；孤立的未匹配 `{{` 保留为行文，替换后的值不会被重新扫描。注册阶段拒绝无效或重复的变量名，section 名称也必须唯一。
+
+`dsh-agent-loop` 注册两个内置变量，均为上下文 agent 的纯投影：`model`（= `options.model`）和 `cwd`（= `session.header.cwd`）。示例 persona 写 `powered by the {{model}} model`——模型名称只在 `model:` 配置键中声明一次。`{{cwd}}` 仅在 ACP 示例中演示：每个 ACP 会话携带客户端的 cwd，而配置预创建的 stdio agent 没有 cwd（在那里声称 `{{cwd}}` 的 persona 会导致该轮次失败——这是有意为之）。变量留在 loop 插件上（不同于下面的 section）：它们是本循环驱动的 agent 的运行时事实，替换循环自行提供自己的变量。
+
+### Persona 作为 order-0 section
+
+`dsh-system-prompt` 拥有 order 为 `-100` 的 `harness:identity` 和 order 为 0 的配置 `deployment:persona`，因此两者在循环被替换时仍然存活。提示词渲染只有一条路径 `renderPrompt(assembly)`，已路由请求 header 因此会记录准确的提示词，稍后由 `ctx.tokenMeter` 为压缩压力回放。agent 作用域的 `deployment:persona` 遮蔽全局默认值，允许 subagent 提供方在发布前安装 persona。约定的 order 区间为：identity `-100`、persona `0`、工具指导 `100–199`。
+
+### 工具指导归属
+
+每个工具的语义和选择指导放在工具 description 中。提示词 section 只承载跨调用习惯，例如检查 bash 退出标记或优先使用文件系统工具而非 shell 命令。`todo_write` 和 subagent 工具不需要 section，因为它们的 description 包含完整契约。部署 persona 只包含角色和行为。
+
+### Subagent 对话历史描述符
+
+`SubagentProvider.inheritsParentContext` 描述的是对话种子，而非作用域、服务、工具或权限。spawn 和 ACP 将其设为 `false`；fork 设为 `true`。`dsh-tool-subagent` 根据该标志派生工具和提示词参数的描述，包括 fork 继承已完成轮次但不继承进行中轮次这一点。提供方生命周期事件使该措辞与响应式提供方注册保持同步；其设计动机见[提供方生命周期事件 Agent Note](2026-07-05-subagent-provider-lifecycle-events.md)。
+
+## 曾考虑的替代方案
+
+- **循环自行组合一行 identity 文本**：在必须保持精简的那个包（「用插件，不改循环」）中硬编码面向模型的行文，且在 section 流水线之外构成第二条组合路径。（identity 确实以代码字面量交付——但作为 `dsh-system-prompt` 注册的普通 section，其 `system-prompt/assemble` waterfall 仍是部署需要移除它时的逃生阀。）
+- **通过 `agent/request` waterfall 注入模型名称**：提示词文本会在两处组合，更早渲染的 persona 也可能与最终已路由 header 不一致。拥有延迟路由的请求插件还必须拥有该模型在提示词中更早出现的声明。
+- **在每个 persona 中手写模型名称**：与上方一行的 `model:` 键重复，配置修改后静默失实；正是本 Agent Note 要治愈的病症。
+- **宽松插值（未知引用保留原样或替换为空）**：一个拼写错误 `{{modle}}`（或一个空洞）会被发送给模型，直到 transcript（文本记录）审查时才会被发现。
+- **在配置中为每个 subagent 实例编写措辞**：面向模型的行文回到每个部署 × 实例中，重蹈 P2 病症。**根据提供方名称选择措辞**：`providerName` 本身是配置，重命名提供方后会静默获得错误的措辞。
+- **在 `apply` 时解析提供方（加载顺序要求）** 与 **仅用 section 承载 subagent 措辞（在 assemble 时惰性解析）**：提供方生命周期事件的替代方案；两者均在[提供方生命周期事件 Agent Note](2026-07-05-subagent-provider-lifecycle-events.md)中被否决。
+
+## 不在范围内
+
+- 更多变量（`date`、platform、git 状态）：注册表使每个变量成为拥有该事实的插件的一行贡献；本 Agent Note 不认领任何一个。
+- 为预创建的 stdio agent 提供配置 `cwd`（可让 stdio persona 使用 `{{cwd}}` 并按真实路径分区持久化）：推迟到会话 cwd 方案重新讨论时。
+
+## 交付的不变式
+
+- tui-agent 的提示词通过一条组装路径依次渲染 identity、带插值模型名的 persona，然后是 fs/bash/web 指导。
+- fork 和 fresh subagent 的描述反映提供方是否继承已完成的对话轮次；工具随提供方生命周期变化而出现、消失和重新措辞。
+- 未知、无值、格式错误或不平衡的变量引用会指明 section 名称并抛出异常；重复的 section、变量和工具注册同样抛出异常。
+- 快照回放与提示词无关：它按轮次和步骤索引已记录的分片流，不比较发出的请求。
+
+## 后果
+
+- 组装后的提示词中每个事实现在恰好有一个归属方，leaf YAML 中手工维护的工具行文已消除：加载或卸载一个工具插件不再需要编辑任何部署的 persona。
+- `{{model}}` 在组装时反映 `AgentOptions.model`。如果一个插件在 `agent/request` waterfall 中切换模型，提示词对该步骤的声明就会过时；如果一个插件在那里提供模型（options.model 未设置——循环文档中记载的回退路径），变量在渲染时无值，包含 `{{model}}` 的 persona 会在 waterfall 运行前失败。两者的补救方式相同，就是归属规则本身：拥有延迟绑定模型事实的插件在 `system-prompt/assemble` waterfall 上提前声明它（`assembly.variables['model'] = …`）——一个归属方，两处声明；一个循环测试端到端固定了 supply 路径。已接受。
+- 当一个已绑定的提供方不存在时（尚未激活、已卸载、HMR（热模块替换）重载中），subagent 工具不存在，该窗口内的模型请求中不会包含它。这是诚实的状态——替代方案是注册一个 description 或执行都不可信的工具。
+- 严格性意味着 persona 可能在渲染时导致轮次失败（例如在无 cwd 的会话上使用 `{{cwd}}`）。失败是受控的——该轮次以 `error` 结束，循环存活——且这是一个我们希望大声暴露的撰写错误。
+- 目前没有在提示词行文中转义字面 `{{name}}` 的语法；如果真实提示词确实需要，再行添加。

## Problem
The request pipeline did not guarantee prefix stability for provider caching, and the session log could not reconstruct what the model saw. It omitted model, system prompt, and tool schemas while allowing per-call request rewrites. Cache behavior and replay equivalence therefore depended on whichever plugins happened to be loaded.

+# Agent Note: 每个 LLM（大语言模型）请求都可从会话日志重建
+
+Status: implemented
+
+[English](2026-07-05-reconstructable-requests.md) | 中文
+
+## 问题
+
+请求流水线未能保证前缀稳定性以利用提供方缓存，会话日志也无法重建模型实际看到的内容。日志遗漏了 model、系统提示词和工具 schema，同时允许逐次调用的请求改写。因此缓存行为和回放等价性取决于碰巧加载了哪些插件。
+
+快乐路径的参考形态是 MiniCode 的 `LLMClient`：一个有状态的对话客户端，随对话推进只做追加而不重建，仅在系统提示词、工具集或压缩（compaction）真正改变了模型需要看到的内容时才重置。本 Agent Note 回答的设计问题是：如何在不放弃事件溯源的前提下获得这种纪律。
+
+## 决策
+
+### 原则
+
+**模型可见 ⟺ 已记录。** 凡到达模型请求的内容都必须记录在会话日志中。可检查的推论：**循环发出的每个对话请求都是会话日志的纯函数**——任何人持有日志即可逐字节重建请求。精确的范围声明：该保证覆盖循环构建的 `GenerateOptions`；提供方协议格式（wire format）字节由此推导而来，因为两个适配器的序列化在固定代码版本下都是逐消息的纯函数；直接的一次性调用（压缩的 summarize 调用）记录其信封标量（`compact/summary.{provider, model, maxTokens}`），其输入是对日志区域的确定性代码运算——可从日志加代码重建，因为只有循环会标记请求归属，所以它们不在不变式内。
+
+前缀缓存稳定性是推论 #1，而非标题：一个仅追加的日志经逐节点纯函数投影，在 header 不变时自然产出前一请求的追加扩展——稳定性是涌现的，不是管理出来的。字节精确的审计/回放是推论 #2；带*可归因*漂移的恢复与 fork 是推论 #3。
+
+### 机制
+
+**消息。** `Session.deriveMessages()` 带缓存：每个 surface 条目在首次出现时通过公开的逐事件函数 `deriveEventMessage(event)` 精确投影一次；surface 重写（压缩的 `replace`，即 `SurfaceManager.replaceGeneration`）触发重建。调用方每次获得一个新数组，底层是共享的深度冻结消息：通过投影变异已记录的历史是不可表达的（会抛异常），取代了旧的逐次调用克隆隔离。外部重建器对日志前缀折叠同一个公开函数，因此不可能有两条路径产生分歧。
+
+`EpochHeader` 记录请求的非历史状态：调用配置、渲染后的系统提示词、工具 schema 和会话前缀，空值规范化为缺失。`request/header` 始终写入完整快照：首个循环实例使用 reason `initial`，后续实例使用 `resume`，实例内变更使用 `change`。`foldRequestHeader` 选择最新快照。旧的 `request/header-delta` 事件和已移除的 `fallback` reason 在追加或加载时都会被拒绝。
+
+每个步骤重建提示词组装。在实例的首个步骤中，`agent/session-prefix` 以一个冻结的空种子为基础，用仅限请求的开场消息进行扩展；结果在通用 `agent/pre-step` 检查点与边界快照之前被冻结并缓存于该循环实例。首次调用配置从显式的 `AgentOptions` 出发，保留 fork 覆盖和恢复重配置；后续调用从折叠后的 header 出发。`agent/request` 只能替换那个冻结的配置种子，模型可见内容通过已记录的通道进入。循环记录欠下的 header 事件（前缀唯一的持久归宿），从前缀、快照和 header 构建 `GenerateOptions`，对其深度冻结但保持 `AbortSignal` 活跃。每实例状态仅有缓存的前缀和锚定快照是否已写入。
+
+**`step/start` 是重建边界。** 一个步骤从该序列之前的事件推导消息。快照之后的注入加入下一次请求，事件发布期间的重入追加被拒绝。`agent/pre-step(agent, turn, step, signal)` 仍是当前请求所需内容的通用 seam。header 重建选择该步骤的 `request/header`，或在无新 header 写入时沿用前一个快照。
+
+**强制执行。** `dsh-agent-loop/invariant` 配套插件向 `ctx.invariants` 注册，并在被选用时通过一个全新的 `Session` 独立重建每个循环请求，使活跃缓存无法为自身背书，然后在 `llm/stream` 处比较消息和折叠后的 header 字段。循环通过 `dsh-llm` 的 `markAgentLoopRequest()` 记录精确的冻结请求；这一进程内标识让配套插件和其他请求观察者识别对话工作，而直接的一次性调用无论其冻结形状或会话 id 如何都保持排除。正确性依赖于序列有界的重建，而非监听器顺序。带密钥的 e2e 要求首次请求之后有正值的 cache-read token；逐步骤用量是生产信号，header 变更或压缩表现为下一步骤的 cache-read 下降。
+
+### MiniCode 形态：采纳，但溯源箭头反转
+
+与 MiniCode 相同，对话仅追加推进，仅在模型可见状态变更时重置。与 MiniCode 不同，事件日志仍是真源，因为它同时拥有持久化、恢复、边界、工具配对和溯源。`Session` 缓存从日志推导的消息和 header 折叠结果，使每个请求都可独立检查。
+
+## 曾考虑的替代方案
+
+- **客户端作为真源**（照搬 MiniCode）：在日志之外多出一个运行时真相——两者漂移而无人察觉；见上节。
+- **镜像日志的有状态传输客户端**：重复对话状态，需要围绕监听器做回滚，留下未记录的编辑面，且仍无法重建请求 header。Session 拥有的缓存加已记录的 header 避免了这些分裂的真相。
+- **逐次调用的请求标量**（一个可自由变异的配置传给每次 `agent/request` 分发）：监听器可以零记账地逐次切换 model，悄然放弃本设计旨在保护的提供方缓存。配置是逐对话的已记录状态；waterfall（瀑布式事件）提议，日志记录。
+- **检测并报告**（比较连续请求，发散时告警）：事后捕获违规；违规请求仍可构造并发出。因接口层面的不可表达性而否决。
+- **事件驱动组装**（仅在变更信号时重新渲染）：存在漏信号的 bug 类别——会话中途注册的工具发出 `tools/change` 而非 `system-prompt/change`，第三方提供方可能什么都不发。逐步骤渲染加值比较在零信号纪律下即可稳健工作。
+- **自定义 header-delta 编解码器**（系统行编辑、按名称键控的工具编辑、完整配置/前缀替换）：减少了重复字节，却复制了表示及其 diff/apply/fallback 机制。完整快照只保留一种回放表示。
+- **Header 快照上的叙事性变更字段列表**：可以通过比较连续快照推导。`reason` 仍保留，因为实例边界无法从快照值推导。
+
+## 后果
+
+- 一个日志无法解释的请求不可能被意外构造——无论是循环还是监听器；变异已构建的请求会抛异常；每个 header 变更都是持久的、可 diff 的日志事件。
+- 在建议性通道之间做选择是变更频率的决策，而本设计使稳定的那个在结构上成为默认：`agent/session-prefix` 的贡献在每个循环实例中只组合一次并逐字复用，因此以零边际成本扩展可缓存前缀，且不可能在会话中途击穿提供方缓存；会话中途变化的内容通过仅追加的历史通道流入——`agent.inject()` 以及工具/prompt-submit 的 `additionalContexts`——每条都是持久的 `context/message`，付出一次代价后即被前缀缓存，代价是在历史和日志中累积。将会话冻结的开场内容路由到前缀，将变更通知路由到历史通道；逐步骤的仅限请求尾部槽位被有意放弃（无消费方，且持久追加覆盖了当前所有更新模式）。
+- 在提供方处仍需全价计算的内容是固有的且已记录的：压缩（其 `compact/*` 事件和替换条目）、真正的提示词、工具或配置变更（reason 为 `change` 的 `request/header`），或带漂移的进程边界（不同的 `resume` 快照）。提供方自身的 reasoning-content 排除由服务端管理。
+- `step/start` 监听器行为变更（见上文）是对插件唯一可观察的语义变更；`agent/pre-step` 是当前请求的 seam。
+- 工具结果裁剪（计划中）无需新机制：一个已记录的单条目 surface replace（`start === end`），携带同一 `callId` 下裁剪后的 `tool/result`——属压缩家族，回放正确，缓存击穿由相同的压力逻辑批量处理。
+- 会话日志每个循环实例增长一个 `request/header` 快照，并在真正变更时增加快照。它比 delta 编解码器更大，但相对分片密集型日志仍然很小，并只保留一种回放表示。`SESSION_FORMAT_VERSION` 保持 `0`；旧的 delta 事件被拒绝而非迁移。
+- 快照预期输出变更一次（每个 transcript（文本记录）增加其 header 事件）；写入文件系统的 fixture（测试前置数据）以规范化的撰写形式存储，工具参数使用 cwd 相对路径，因为回放只对 cwd 无关的参数路径做往返。
+- FIXME(call-config-shape)：重新审视 `LlmCallConfig` 的确切字段集——哪些字段对缓存而言真正属于 epoch 级别（`model` 毫无疑问；采样标量出于谨慎放在那里），以及当适配器需要时，提供方特定的额外项（reasoning 选项、额外 body 参数）应归属何处。

## Problem
[The prompt-variables Agent Note](2026-07-05-prompt-variables-and-tool-guidance-ownership.md) makes `dsh-tool-subagent` DERIVE its model-facing wording from its provider: `SubagentProvider.inheritsParentContext` (spawn/ACP `false`, fork `true`) drives both the tool description and the `prompt` parameter description, so the fork tool stops lying about context inheritance. That fix created a cross-fiber data dependency: a tool's description is fixed at TOOL REGISTRATION (deliberately — the description is where tool-choice guidance lives), but the provider arrives on its own plugin fiber, on no particular schedule.

+# Agent Note: Subagent 提供方生命周期事件——`subagent/provider-added` / `subagent/provider-removed`
+
+Status: implemented
+
+[English](2026-07-05-subagent-provider-lifecycle-events.md) | 中文
+
+## 问题
+
+[提示词变量 Agent Note](2026-07-05-prompt-variables-and-tool-guidance-ownership.md) 让 `dsh-tool-subagent` 从其提供方派生面向模型的措辞：`SubagentProvider.inheritsParentContext`（spawn/ACP 为 `false`，fork 为 `true`）同时驱动工具描述和 `prompt` 参数描述，使 fork 工具不再在上下文继承问题上对模型撒谎。这一修复引入了跨 fiber 的数据依赖：工具描述在工具注册时固定（这是有意为之——描述是 tool-choice 引导所在之处），但提供方在自己的插件 fiber 上到达，时机不确定。
+
+如果在工具插件的 `apply` 时刻解析提供方，就会产生一个隐式的加载顺序要求（「在 cordis.yml 中把后端列在工具前面」）。这个要求不成立，因为 Cordis Loader 并发启动同级条目，且 `Entry.init()` 不会等待激活完成：延迟到达的后端即使列在前面，也可能让工具 fiber 失败。Loader 不提供同级顺序保证——「异步状态不是同步状态」（见[防御性模式](../../../../docs/defensive-patterns.md)）。
+
+## 决策
+
+注册表将提供方的成员变化作为类型化事件广播，消费方镜像这些事件而非假设顺序：
+
+- **`subagent/provider-added(provider)`**：一个提供方在 `ctx.subagents` 注册表中变为可解析。在注册时发出。
+- **`subagent/provider-removed(name)`**：一个提供方离开注册表（其插件 fiber 被 dispose（资源释放）——卸载或 HMR（热模块替换）重载）。从注册的 disposer 中发出。
+
+`dsh-tool-subagent` 镜像其命名提供方的生命周期：当提供方可用（或变为可用）时注册工具——在那一刻从该提供方派生措辞——当提供方离开时注销工具，并在重新注册时（HMR 重载）重新派生。提供方不在时工具不存在，因此不会对模型撒谎。这里有意不留下任何需要文档化的加载顺序要求：事件让顺序问题消失，而非将其钉死。
+
+这些事件还完善了 seam 的词汇：`ctx.subagents` 是一个命名注册表，多个委派后端（`spawn`、`fork`、`acp`）在其上共存；一个其他插件从中派生状态的注册表，应当以类型化事件广播成员变化，而非要求轮询或依赖加载顺序。
+
+## 曾考虑的替代方案
+
+- **在 `apply` 时解析提供方，不存在则抛异常**：否决。「先列后端」这一要求声称了 Loader 并不存在的顺序保证。
+- **重试查找（轮询直到提供方出现）**：最终能收敛，但在框架已有的机制（effect 注册 + disposal）之外发明了一套私有就绪协议；它也无法感知提供方离开，因此 HMR 会遗留一个措辞描述已 dispose 后端的工具。
+- **仅在 section 中放置 subagent 措辞，在组装时惰性解析**：同样能容忍任意加载顺序，但将 tool-choice 引导移出了描述，与提示词变量 Agent Note 建立的所有权规则相矛盾（每个工具的语义和何时使用属于描述）。响应式注册既保持描述的权威性，又不依赖顺序。
+- **根据提供方名称而非提供方对象确定措辞**：`providerName` 本身是配置，重命名后的提供方会静默获得错误的措辞；从已解析提供方自身的 `inheritsParentContext` 派生则不会漂移。
+
+## 后果
+
+- 从命名提供方派生状态的消费方响应 `subagent/provider-added`/`-removed` 事件，而非在 `apply` 时读取注册表；`dsh-tool-subagent` 是参考实现。
+- **添加时大声失败；移除时按监听器隔离。** 添加监听器可以回滚注册。移除在 disposal 期间运行，因此单个监听器抛异常只会被记录日志，不会饿死后续镜像或干扰拆解流程。`start()` 仍在每次运行时按名称解析提供方，防止陈旧工具调用已移除的后端。见[事件目录](../../../../docs/cordis-catalog/events.md)与[生产者/消费方映射](../../../../docs/event-producer-consumer.md)。
+- **工具不存在的窗口期。** 在后端 disposal 与重新注册之间（HMR 重载期间），模型看不到 subagent 工具。这是诚实的状态——替代方案是一个向空处分发的工具——工具注册表的 `tools/change` 事件发出会保持提示词组装的时效性。
+- **两个等待中的 fiber 共享同一 `toolName` 是无效配置，被延迟捕获。** 如果两个 `dsh-tool-subagent` 加载实例命名了不同的提供方但相同的 `toolName`，两者都会等待，先到达的提供方先注册；第二次注册仅在其提供方到达时才抛异常。插件中的 `TODO(subagent-dup-toolname)` 记录了这一影响范围；工具注册表的重名拒绝机制仍是最终防线。

-# Agent Note: Windows write-permission semantics — inherited DACLs, not mode bits
-
-Status: implemented
-
-The replacement-file decision in this record is superseded by [Windows DACL preservation](../bug-fix/2026-07-19-windows-atomic-write-dacl-preservation.md).
-
-## Problem
-
-`writeFileAtomic` in `@deepseek-ai/dsh-fs-local` protects write-in-progress content with POSIX mode bits: the staging directory is created `0o700`, the temp file is opened `0o600`, and new files default to `0o600`. On POSIX this keeps temporary content owner-only regardless of the parent directory's permissions.
-
-Windows has no working equivalent behind the same API. Node's `chmod` there drives only the read-only attribute (every mode this package passes carries owner-write, so the calls are benign no-ops), and `stat().mode` reports synthetic `0o666`/`0o444` bits. The real security state is the file's DACL: a newly created file or directory inherits from its parent, while replacement needs the explicit handling owned by the superseding Agent Note.
-
-## Decision
-
-New Windows files use directory inheritance rather than synthetic mode bits: the staging directory is created inside the target's parent directory (`dirname(absolutePath)`), so it and the temp file inherit the destination directory's DACL. Replacement files follow the stricter [DACL preservation contract](../bug-fix/2026-07-19-windows-atomic-write-dacl-preservation.md).
-
-Tests assert mode bits on POSIX only. Native Windows coverage pins the package-owned replacement behavior; new-file inheritance remains an operating-system contract rather than a machine-specific ACL allowlist.
-
-## Alternatives considered
-
-**Explicit owner-only DACLs for new files.** Rejected because they would break inheritance and surprise users whose project directories are deliberately shared. Replacement writes copy the target's existing DACL rather than inventing an owner-only policy.
-
-**Test-side ACL verification.** A `Get-Acl` SID allowlist or `icacls` would verify Windows inheritance and the machine's `%TEMP%` ACL rather than package behavior; `icacls` also localizes well-known account names, making parsing locale-fragile.
-
-**Skip `chmod` on Windows.** Platform-guarding benign no-op calls adds branches without changing behavior.
-
-## Consequences
-
-POSIX keeps owner-only temp content regardless of the parent directory. A new Windows target inside a broadly accessible directory inherits that accessibility by design; a replacement retains the target's narrower DACL when one exists.

## Problem
Timeout handling was drifting apart across the tool-bearing capabilities, and the divergence was not superficial — it was the same logic re-implemented three ways, each with its own subtle correctness burden.

+# Agent Note: 共享的超时/截止时间原语，硬终止留给各能力自行实现
+
+Status: implemented
+
+[English](2026-07-06-timeout-deadline-library.md) | 中文
+
+## 问题
+
+超时处理在各个承载工具的能力之间逐渐分化，而且这种分化并非表面的：同一套逻辑被以三种方式重新实现，各自带有微妙的正确性负担。
+
+- **bash**（[packages/bash/bash-local/src/run.ts](../../../../packages/bash/bash-local/src/run.ts)）在进程管道内部有一套完整、正确的超时实现：一个经配置钳位的 `timeoutMs`，两个独立触发器（用于超时的 `killTimer` 和用于上游取消的 `onAbort` 监听器），各自调用同一个 `kill()` 闭包对进程组执行 SIGTERM→宽限期→SIGKILL 升级，以及两个正交的结果布尔值（`timedOut`、`aborted`）独立锁存。
+- **web_fetch**（[packages/web/web-fetch-local/src/provider.ts](../../../../packages/web/web-fetch-local/src/provider.ts)）有一套正确但*手写*的超时：构造一个 `AbortController`，连接 `setTimeout(() => controller.abort(new WebError(…, 'WEB_FETCH_TIMEOUT')))`，手动添加和移除上游信号监听器，在 `finally` 中清除定时器，并在 `translateAbortOrNetwork` 辅助函数中从 `signal.reason` 恢复超时原因（因为 reader 只抛出裸 `AbortError`）。
+- **web_search**（[packages/web/tool-web/src/search.ts](../../../../packages/web/tool-web/src/search.ts)）**完全没有超时**：`WebSearchRequest`（[packages/web/web/src/types.ts](../../../../packages/web/web/src/types.ts)）不携带 `timeoutMs` 字段，各提供方的 `search()` 只转发 `exec.signal`。（web_search 在本次设计中保持无超时——见「后果」。）
+
+每个新的外部进程或网络工具都要重新推导同样四件事：钳位请求值、启动定时器、将超时与上游取消融合、在出口处区分「超时」与「已取消」。而融合与原因恢复恰恰是最容易出微妙错误的部分（web_fetch 的 `signal.reason` 处理就是证据）。与此同时，各能力执行的*终止*操作不可归约地不同：bash 杀死一个 OS 进程组（工作运行在子进程中，在本运行时之外，只能通过信号触达），而 web 中止一个进程内的 `fetch`（undici 拆除 socket）。不存在一个能停止所有能力工作的单一机制。
+
+## 决策
+
+`@deepseek-ai/dsh-timeout` 位于 `packages/util/`（与 `dsh-brand` 同级），负责超时的*计时与分类*这一半；*终止*那一半——硬终止——留在各能力的实现中。它是一个纯函数库，**不是** Cordis 服务或插件：不接收 `ctx`、不注册任何东西、不持有跨调用状态、不发射事件。这里刻意不设中央「超时服务」，因为那样的服务必须知道如何停止每个能力的工作——而这正是微内核要排除在共享层之外的知识，也是 Codex 将 `ExecExpiration` 限定于 exec 族所示范的原则。
+
+### 库的对外接口
+
+四个函数、一个 watchdog 接口加一个 reason 类型：
+
+```ts ignore-check
+/** The internal reason attached to a timeout abort, so consumers can classify it after the fact. */
+export class TimeoutReason extends Error {
+ override name = 'TimeoutReason'
+
+ constructor(readonly code: string, readonly timeoutMs: number) {
+ super(`${code} after ${timeoutMs}ms`)
+ }
+}
+
+/** Validate/fill a caller's optional positive hint from the backend's default, then cap at its max. */
+export function clampTimeout(
+ requested: number | undefined,
+ def: number,
+ max: number,
+ name = 'timeoutMs',
+): number
+
+/**
+ * Build a deadline signal that aborts on upstream cancellation OR on timeout,
+ * with the timeout carrying a `TimeoutReason`. `timeoutMs <= 0` means "no
+ * timeout" (background tasks): forward only the upstream signal, arm no timer.
+ * The returned object's `[Symbol.dispose]` clears the timer — `using` for a
+ * scope-lifetime consumer, a manual call for an event-lifetime one.
+ */
+export function deadline(
+ upstream: AbortSignal | undefined,
+ timeoutMs: number,
+ code: string,
+): { signal: AbortSignal; [Symbol.dispose](): void }
+
+/** A stable signal plus one-at-a-time, timer-guarded async-iterator demand. */
+export interface IdleWatchdog {
+ readonly signal: AbortSignal
+ next<T>(iterator: AsyncIterator<T>): Promise<IteratorResult<T>>
+ [Symbol.dispose](): void
+}
+
+/** Arm only while one iterator `next()` is outstanding, then rearm on later demand. */
+export function idleWatchdog(
+ upstream: AbortSignal | undefined,
+ timeoutMs: number,
+ code: string,
+): IdleWatchdog
+
+/** Recover the TimeoutReason from an aborted signal (or error); `code` scopes the match to this deadline's timer. */
+export function timeoutOf(x: AbortSignal | { reason?: unknown }, code?: string): TimeoutReason | undefined
+```
+
+`deadline` 通过 `AbortSignal.any` 将上游信号与一次性定时器融合，附加一个类型化的 `TimeoutReason`，并暴露可 dispose（资源释放）的定时器清理。非正数超时是内部的「无超时」哨兵，用于后端拥有的后台任务；外部提示经过 `clampTimeout`，必须为正有限值。既无定时器也无上游信号时，函数返回一个永不中止的信号，具有相同的 disposal 形状。`idleWatchdog` 则要求正有限的间隔，在整个流期间保持一个稳定的融合信号，并且只在一个迭代器 `next()` 尚未结算时启动定时器；结算会解除定时器，后续 demand 会重新启动，并发 demand 会失败，dispose 会清除当前 arm。提供方将超时原因转译为 seam 特定的结果。`timeoutOf(signal, code)` 限定分类范围，使外层嵌套的 deadline 被视为上游取消而非内层能力自身的超时。
+
+### 职责划分
+
+| 关注点 | 负责方 |
+|---|---|
+| 校验请求提示并钳位默认值/最大值 | `dsh-timeout`（`clampTimeout`）：纯算术加共享的正有限请求契约 |
+| 启动一次性定时器、到期中止、携带 reason、与上游取消融合 | `dsh-timeout`（`deadline`） |
+| 仅围绕未结算的迭代器 demand 启动和重启 | `dsh-timeout`（`idleWatchdog`） |
+| 清除定时器 | `dsh-timeout`（任一原语的 `[Symbol.dispose]`） |
+| 中止后对首个 abort reason 进行分类 | `dsh-timeout`（`timeoutOf`） |
+| **实际终止工作** | 各能力的实现 |
+| 默认值/最大值*数值* | 各能力的配置 |
+| 超时 `code` 字符串 | 各能力（`WEB_FETCH_TIMEOUT` ≠ `BASH_TIMEOUT`） |
+
+信号只*通知*；终止始终是监听方的职责，而监听方因能力而异。bash 自行编写 `addEventListener('abort', kill)`，因为 OS 进程存在于本运行时之外，没有别的东西会杀死它；web 将 `d.signal` 交给 `fetch`，由 undici 拆除 socket。这也是文件读/写/编辑**不接受** `timeoutMs` 的原因：本地系统调用最多只能尽力中止，超时无法强制 `fsync`/`rename` 停止，添加超时将是一个违反「显式优于隐式」的隐式默认值。两个参考 agent 出于同样的原因对文件 I/O 不设超时。
+
+### 各能力如何消费该库
+
+- **web_fetch**：工具层保持校验并转发；提供方手写的 controller + `setTimeout` + 手动监听器 + `finally` + `signal.reason` 恢复被替换为提供方自有的 `deadline`/`timeoutOf`。已预先中止的上游信号仍然立即抛出 `WEB_ABORTED`；否则 `fetch` 使用融合后的 `d.signal` 运行，`translateAbortOrNetwork` 根据信号分类抛出的错误（`timeoutOf` → `WEB_FETCH_TIMEOUT`，否则已中止 → `WEB_ABORTED`，否则网络错误 → `WEB_PROVIDER_ERROR`）。公开的错误码契约不变，`TimeoutReason` 永远不会作为公开错误跨越 web seam。
+- **bash**：`resolve()` 将请求钳位为显式规格。前台 `run()` 创建 deadline 并将其信号传给进程执行，后者既有的 abort 监听器执行进程组 kill。执行器将首个 abort 分类为超时或取消。后台启动保持无超时，仅转发上游取消。
+- **LLM 适配器**：`dsh-llm-deepseek` 和 `dsh-llm-pi-ai` 用 `idleWatchdog` 包装实际的传输迭代。配置的五分钟间隔只覆盖尚未结算的提供方 demand，不包括下游消费方在分片之间花费的时间。稳定信号在整个调用期间传给 `fetch` 或 SDK，因此超时会关闭底层请求并映射为 `TIMEOUT`，而更早的调用方中止映射为 `ABORTED`。
+
+## 后果
+
+- `runBash` 的结果不再独立锁存 `timedOut` 和 `aborted`；超时与用户中止在进程关闭前竞争时，现在报告单一的首个 abort 原因，而非两者同时为 true。统一的 SIGTERM→宽限期→SIGKILL 终止路径不变，seam 类型 `BashRunResult` 保留两个布尔值（现在互斥），因此 `dsh-tool-bash` 的结果渲染不受影响。
+- `SpawnSpec.timeoutMs` 和 `SpawnOutcome.timedOut`/`aborted` 被移除，而非作为始终为零/始终为 false 的残余保留：由于 `runBash` 不再拥有定时器且执行器负责分类，这些字段无处被读取。这是与字面提案形状（向 `runBash` 传入 `timeoutMs: 0`）的唯一偏差；一个始终为 0 且无处读取的字段在逐文件覆盖率门禁下属于死代码。
+- web_fetch 去除了其定制的 controller/timer/listener/reason-recovery；分类器现在基于 deadline 信号（`timeoutOf` + `aborted`）而非抛出错误的形状来判断，这在请求阶段的 reject-with-reason 和读取阶段的裸 `AbortError` 两种情况下都是健壮的。
+- `AbortSignal.any` 和 `using`/`Symbol.dispose` 在此首次进入本仓库（Node ≥ 24 基线，已满足）。
+- 模型流现在共享一个可重启的定时器契约，不会把滑动的空闲间隔变成总调用截止时间，也不会计入消费方思考时间。该原语仍然只做通知；适配器测试证明其传输观察到稳定信号并终止。
+
+以下内容不在本次范围内，列出以标明边界：`web_search` 可以在其工具 schema/快照覆盖率规划就绪后获得可选的面向模型的 `timeout_ms`；未来基于 ripgrep 的文件系统发现工具可以在存在后消费同样的提供方自有 deadline 形状；`tools/execute` waterfall（瀑布式事件）中间件可以通过驱动 `exec.signal` 为每次工具调用设置默认 deadline——那将是一个*消费*本库的插件，仍然只做通知，硬终止仍是各能力自己的事。
+
+## 曾考虑的替代方案
+
+**统一的超时*插件* / `ctx.timeout` 服务。** 基于微内核原则否决。一个能停止任何工具工作的服务必须理解每个能力的终止机制（进程组 SIGKILL、socket 拆除、系统调用边界检查），这正是架构所禁止的「内核知道太多」。Codex 的 `ExecExpiration` 被限定于 exec 族，正是因为它驱动的 kill（`killpg`）是进程族特有的；MCP 和模型流各自保有自己的。不存在一个连贯的中间层能为所有东西拥有终止权，因此共享部分只能是纯计时/分类那一半——一个库，而非服务。
+
+**每个工具各自实现超时，不共享代码（先前的现状，也是 Claude Code 的选择）。** 否决，因为它已经在产生分化和重复的正确性负担：web_fetch 手写了与未来网络/进程类工具各自需要重新推导的完全相同的 controller/reason 逻辑，而融合 + `signal.reason` 恢复正是容易出错的部分。Claude Code 容忍完全重复；本仓库有一个统一的共享 abort 通道（每次 `execute` 上的 `exec.signal`），使得一个小型共享原语严格更优，因此成本/收益不同。
+
+**用 `withTimeout(promise, ms)` 包装器代替信号工厂。** 否决，因为让 promise 与定时器竞争只是在截止时间到达时 resolve *工具调用*的 promise，而不会停止底层工作——子进程或 fetch socket 会泄漏。分发信号并要求能力监听，才能强制一条真实的终止路径存在。这与「dispose 必须达到完全停稳，而非仅仅请求它」的防御性规则一致。
+
+**保留 bash 独立的超时和取消触发器。** 否决，因为一个 deadline 信号移除了定制定时器并标准化了分类。竞争的原因报告先到达的那个 abort，而既有的 SIGTERM→SIGKILL 终止路径保持不变。

## Problem
The [timeout/deadline Agent Note](2026-07-06-timeout-deadline-library.md) extracted the timing-and-classification primitive into `@deepseek-ai/dsh-timeout`, but timeout policy was still attached to individual capabilities and model-facing schemas. `bash` exposed `timeoutMs`; `web_fetch` exposed `timeout_ms`; `web_search` had no model-facing timeout even though providers already honor `exec.signal`; a future grep/glob tool would either import the timeout library directly or invent its own timeout policy. That is the wrong authoring shape for a plugin SDK: a tool author should normally forward `exec.signal` to the implementation it calls, and deployment policy should decide the budget.

+# Agent Note: 工具调用超时策略作为插件
+
+Status: implemented
+
+[English](2026-07-07-tool-call-timeout-policy.md) | 中文
+
+## 问题
+
+[超时/截止时间 Agent Note](2026-07-06-timeout-deadline-library.md) 将计时与分类原语提取到了 `@deepseek-ai/dsh-timeout`，但超时策略仍然附着在各个能力和面向模型的 schema 上。`bash` 暴露了 `timeoutMs`；`web_fetch` 暴露了 `timeout_ms`；`web_search` 没有面向模型的超时参数，尽管提供方已经遵循 `exec.signal`；未来的 grep/glob 工具要么直接导入超时库，要么自行发明超时策略。对于一个插件 SDK 来说，这是错误的编写范式：工具作者通常只需将 `exec.signal` 转发给其调用的实现，而部署策略来决定预算。
+
+与此同时，仓库中并非所有超时都是面向模型的工具调用预算。钩子通过直接调用 `ctx.bash` 执行命令钩子，而非通过 `ctx.tools.execute()`；`bash` 模型工具通过同一个后端复用前台执行、后台启动、后台轮询和钩子调用。一步到位地将所有超时移入工具插件会混淆这些路径，并有破坏钩子超时语义的风险。
+
+## 决策
+
+工具调用超时是仅适用于面向模型的工具执行的策略，由三部分组成：
+
+- `@deepseek-ai/dsh-timeout` 仍是拥有 `deadline()` 和 `timeoutOf()` 的共享库。
+- `@deepseek-ai/dsh-tools` 在 `tools/pre-execute` 和 `tools/post-execute` 之间有一个环绕分发的 waterfall（瀑布式事件）`tools/execute`。
+- `@deepseek-ai/dsh-timeout-policy` 从注册表读取每个工具声明的 `timeoutMs`，并通过派生新的 `exec.signal` 来包装有此声明的调用。
+
+执行流水线如下：
+
+```text
+ctx.tools.execute(exec)
+ -> tools/pre-execute
+ -> tools/execute
+ -> registry dispatch (the base next())
+ -> tool.execute(args, exec)
+ -> thrown tool errors normalize to ToolExecutionResult
+ -> tools/post-execute
+```
+
+默认行为是保守的：未声明 `timeoutMs` 的工具不会从该插件收到 `TOOL_TIMEOUT` 截止信号。
+
+### `tools/execute` 环绕 seam
+
+`@deepseek-ai/dsh-tools` 声明了一个 `tools/execute` waterfall，其基础 `next()` 是带规范化的分发 thunk——即同一个内部 `try`/`catch`，将抛出的工具错误（或未知工具错误）转换为 `isError` 的 `ToolExecutionResult`。监听器接收 `(exec, next)`：调用 `next()` 委托给分发（返回其结果，可选地包装），或返回替代结果以短路分发。整个流水线仍位于 `execute` 的外层 try/catch 内，因此抛出异常的监听器会变成 `isError` 结果，而非轮次失败。
+
+catch 是基础 `next`（而非 waterfall 之外的东西）这一点至关重要：当提供方看到超时信号并抛出自己的上游中止错误时，注册表分发首先将其转换为普通错误结果，然后 `timeout-policy` 才能将最终结果替换为 `TOOL_TIMEOUT`。
+
+### `timeout-policy` 插件
+
+该插件是 `@deepseek-ai/dsh-timeout-policy`，一个零配置的函数/命名空间插件（`name` / `inject` / `apply`），位于 `packages/timeout/` 组。每个工具的预算声明在工具自身，而非本插件：`ToolDefinition` 携带一个可选的 `timeoutMs`，由拥有该工具的插件从自身配置中设置。例如 `dsh-tool-web` 将 `fetchTimeoutMs` / `searchTimeoutMs`（默认 30000）解析到 `web_fetch` / `web_search` 的定义上：
+
+```yaml
+- id: timeout-policy
+ name: '@deepseek-ai/dsh-timeout-policy'
+- id: tool-web
+ name: '@deepseek-ai/dsh-tool-web'
+ config:
+ fetchTimeoutMs: 30000
+ searchTimeoutMs: 30000
+```
+
+超时放在工具定义上而非自由文本名称映射中，消除了拼错名称导致策略不生效的问题。`defineTool` 校验预算为正有限数。分发期间，执行器派生截止信号并将其赋给 `exec.signal`；注册表依据[工具取消契约](2026-07-19-cooperative-tool-cancellation.md)，在执行工具体之前将该截止信号与调用方的原始信号融合。执行器随后恢复调用方信号，并将自身的超时转换为 `TOOL_TIMEOUT`；没有预算的工具原样通过。
+
+信号替换采用**就地修改 `exec.signal`** 的方式，而非向 `next()` 传递新对象。Cordis 的 waterfall `next()` 忽略传入的任何参数，并以共享的 payload 数组重新调用下游监听器（`vendor/cordis/src/events.ts`），因此修改共享对象是包装器向注册表提供截止信号的方式。注册表会在进入工具体前再次融合已捕获的调用方信号；插件则在 `finally` 中将 `exec.signal` 恢复为调用方的原始值，使 `tools/post-execute` 永远不会看到本插件的截止信号。
+
+`timeout-policy` 拥有 `TOOL_TIMEOUT` 代码的两种用途：传递给 `deadline()`/`timeoutOf()` 的内部截止代码（有作用域，使嵌套的外层截止读为普通取消）和结构化工具结果错误代码。其替换结果为：
+
+```ts ignore-check
+function toolTimeoutResult(timeoutMs: number): ToolExecutionResult {
+ return {
+ content: [{ type: 'text', text: `Error: tool call timed out after ${timeoutMs}ms` }],
+ isError: true,
+ error: {
+ message: `tool call timed out after ${timeoutMs}ms`,
+ info: { name: 'ToolTimeoutError', code: 'TOOL_TIMEOUT' },
+ },
+ }
+}
+```
+
+这是一个协作式截止。它不会通过竞争工具 promise 来杀死任意工作；工具或其调用的能力必须遵循 `exec.signal` 并达到完全停稳。因此声明 `timeoutMs` 意味着「此工具与 `exec.signal` 协作」，插件 README 将此作为其契约。
+
+无需新的会话事件来保证可重建性：`TOOL_TIMEOUT` 是该调用的最终面向模型的 `tool/result`，因此现有会话日志已经记录了下一次模型请求所见的内容和结构化 `{ name, code }` 错误。
+
+### 现有工具适配
+
+`web_fetch` 和 `web_search` 已迁移。`dsh-tool-web` 保留对其面向模型 schema 的所有权，这些 schema 不暴露超时旋钮：`web_fetch` 移除了 `timeout_ms` 参数以匹配参考 agent 的形状，`web_search` 保持仅查询。工具体不导入 `@deepseek-ai/dsh-timeout`；它们将 `exec.signal` 转发给 `ctx.web`。
+
+`dsh-web-fetch-local` 保留一个配置级别的 `timeoutMs` 作为大型资源兜底，服务于直接调用 `ctx.web.fetch()` 的调用方和配置错误的部署；它不拥有面向模型的超时。当 `TOOL_TIMEOUT` 信号先到达 fetch 提供方时，提供方作用域的分类将其视为上游 `WEB_ABORTED`，而外层 `tools/execute` 包装器将最终工具结果替换为 `TOOL_TIMEOUT`。一个已发布的 web 工具部署将提供方兜底配置为高于 `timeout-policy` 预算，使工具调用策略在模型调用中通常胜出。
+
+`bash` 保持当前的后端超时路径。`dsh-tool-bash` 继续暴露 `timeoutMs` 和 `run_in_background`；`dsh-bash-local` 继续使用 `@deepseek-ai/dsh-timeout` 处理 `BASH_TIMEOUT`；钩子桥接继续调用 `runHook()` 并通过 `ctx.bash` 传递 `timeoutMs`。这保持了前台/后台/钩子行为的稳定。
+
+`read`、`write`、`edit`、`todo_write`、`task_list` 和 `task_kill` 不加入工具调用超时。`task_output` 自己拥有有界等待，因为等待超时是成功的实时状态结果，而非工具失败。
+
+未来面向模型的 grep/glob 工具可以基于 `ctx.bash` 实现而无需导入 `@deepseek-ai/dsh-timeout`：它将 `exec.signal` 转发给 `ctx.bash`，并声明自己的 `timeoutMs`（来自其插件配置）供执行器应用。如果 bash-local 的后端超时对这类工具造成问题，bash seam 可以后续添加调用方自有截止模式；这不在本次范围内。
+
+## 曾考虑的替代方案
+
+**将插件命名为 `tool-timeout`。** 字面的 Agent Note 名称匹配了 `gen-tool-catalog` 完整性守卫的 `packages/*/tool-*` glob，该 glob 要求每个匹配项注册一个面向模型的工具。本插件不注册任何工具——它是一个 `tools/execute` 包装器——因此 `tool-*` 名称要么导致 `verify-tool-catalog` 失败，要么强制产生一个误导性的启动条目。包（package）为 `@deepseek-ai/dsh-timeout-policy`，位于新的 `packages/timeout/` 组；cordis.yml 的 `id` 仍可为 `timeout-policy`。
+
+**仅保留逐工具的超时处理。** 这是 `bash` 和 `web_fetch` 的既有形态，也与 Claude Code 和 Codex 对 shell 命令的做法一致。它对 web 类工具不利，因为每个新的支持超时的工具都必须自行选择校验方式、上限语义、文档、快照和分类。插件集中了策略和分类，让每个工具的 schema 专注于业务输入。
+
+**立即将所有超时策略移出 bash-local。** 长期来看更干净——bash-local 将成为纯子进程执行器，所有调用方自行管理截止时间。但作为第一步不合适，因为钩子直接调用 `ctx.bash`，且 bash 模型工具的前台/后台语义与工具调用生命周期不同。保留 `BASH_TIMEOUT` 维持了这些路径的稳定，同时让工具调用超时在更简单的工具上先行验证。
+
+**为所有工具使用全局默认预算。** 方便，但会让工具作者意外：任何偶然运行超过全局预算的工具在插件加载后就会开始失败。逐工具声明预算使采纳成为有意的行为。
+
+**暴露面向模型的 `timeout_ms` 覆盖参数。** Claude Code 的 `WebFetch`/`WebSearch` 和 Codex 的 web 工具将超时排除在模型调用形状之外。模型覆盖会使超时成为提示词语义的一部分，并迫使 `timeout-policy` 引入 schema/参数剥离规则。Web 超时仅作为部署策略。
+
+**让 `timeout-policy` 自行匹配工具参数。** 诸如「当 `bash.run_in_background` 为 true 时禁用超时」之类的规则引擎会让策略插件了解工具特定的参数语义。通过不将 bash 迁移到工具调用超时来规避此问题。
+
+**使用 `tools/pre-execute` 加 `tools/post-execute` 代替新的环绕 seam。** pre 监听器可以启动截止时间并修改 `exec.signal`；post 监听器可以分类并替换。这样做的问题是截止时间的生命周期会跨越两个独立的 waterfall：需要 call-id 映射、在每条 pre-deny/tool-throw/post-throw/dispose 路径上清理，以及与其他监听器的排序规则。`tools/pre-execute` 也是允许/拒绝门禁，而非执行包装器。`tools/execute` 给超时一个词法作用域：启动、委托、分类、释放。
+
+**使用 `Promise.race` 对非协作工具强制超时。** 与超时库 Agent Note 相同的理由否决：它在底层进程、fetch 或提供方操作可能仍在运行时就将控制权返回给调用方。插件只发送信号；终止仍是实现方的责任。
+
+## 后果
+
+- `@deepseek-ai/dsh-tools` 在有意拆分 pre/post 工具钩子的拦截 seam 之后，获得了一个环绕分发的表面。其契约是狭窄的——包装注册表分发，而非替代 pre 门禁或 post 结果策略——且基础 `next()` 是带规范化的分发，因此包装器永远不会看到原始的工具抛出。
+- 多个 `tools/execute` 监听器按普通 Cordis waterfall 顺序组合：调用 `next()` 的监听器包装下游监听器加分发；不调用 `next()` 直接返回的监听器短路它们。一个同时组合超时与未来重试/沙箱/指标包装器的部署通过注册顺序选择语义（「超时覆盖整个重试」vs「超时覆盖每次尝试」）。
+- 按声明加入是一个有意的误配置风险：工具可以声明 `timeoutMs` 但不遵循 `exec.signal`，这样的工具在超时时不会停止。注册表会等待这一未达完全停稳的工具体，而不是竞速它；同时插件契约声明：声明预算意味着协作；web 工具在已转发信号的工具上验证了这一模式。
+- 过渡期间 `bash` 和已迁移的 web 工具有意使用不同的超时路径：`TOOL_TIMEOUT` 是面向模型的工具调用预算，而 `BASH_TIMEOUT` 仍是 bash 和钩子使用的 bash 后端超时。
+- 与字面提案的偏差，按 implemented-Agent Note 规则记录：插件包为 `@deepseek-ai/dsh-timeout-policy`（而非 `tool-timeout`）；信号替换是在 `next()` 之前就地修改 `exec.signal`（而非 `next({ ...exec, signal })`，Cordis 会忽略后者）；逐工具预算声明在 `ToolDefinition` 上（`timeoutMs`，由拥有该工具的插件从其配置中设置），而非在本插件配置中按工具名映射——因此执行器是零配置的，拼错工具名不可能发生。以上三点均在上文 `## Decision` 中描述。

## Problem
One application needs to share infrastructure across many agents while letting each agent have its own tools, prompt contributions, policies, and listeners. Shared adapters, persistence, and user interfaces belong to the deployment; a persona, tool variant, or listener often belongs to one agent.

+# Agent Note: agent 即注册作用域
+
+Status: implemented
+
+[English](2026-07-08-agent-scope-contexts.md) | 中文
+
+## 问题
+
+一个应用需要在多个 agent（智能体）之间共享基础设施，同时让每个 agent 拥有自己的工具、提示词贡献、策略和监听器。共享的适配器、持久化和用户界面属于部署层面；而 persona、工具变体或监听器往往只属于某一个 agent。
+
+为每个 agent 建立独立的服务图会重复共享基础设施。使用一个全局注册图则有相反的问题：某个 agent 特有的贡献可能泄漏到无关的 agent 中。贡献者需要一种普通的注册机制，既能决定谁可以看到某项贡献，又能决定何时清理它。
+
+该机制还需要一个发布边界。agent 在其本地世界构建完成之前不得变为可见，拆除时也必须保留该本地世界直到最终工作停止。
+
+## 决策
+
+每个存活的 agent 拥有一个扁平的注册层，通过 `agent.ctx` 暴露。代码通过拥有某项贡献的上下文进行注册；具备作用域感知的服务将部署全局注册与恰好一个匹配的 agent 层合并；操作从其真实 agent 选择该层；该层在 agent 的完整发布生命周期内存在。
+
+Cordis 是 SDK 底层的插件框架。Cordis **上下文**是插件用来访问服务和注册效果的对象，效果的清理跟随该上下文。[Cordis 入门](../../../../docs/cordis-primer.md)对该框架有更详细的说明。
+
+对大多数贡献者而言，完整契约是四条规则：
+
+| 问题 | 规则 |
+|---|---|
+| 在哪里为某个 agent 注册行为？ | 通过 `agent.ctx` 调用普通注册 API |
+| 某个 agent 的操作能看到什么？ | 部署全局加上该 agent 的层，按所属服务的合并规则 |
+| 哪些作用域监听器会运行？ | 无作用域监听器加上为该操作所属 agent 注册的监听器 |
+| 该层存在多久？ | setup 在发布前完成；dispose 保留该层直到工作完全停稳 |
+
+作用域是扁平的。解析永远不会遍历父级或兄弟作用域，生命周期所有权也不意味着注册继承。
+

+ globalLayer --> agentBView
+ agentBLayer --> agentBView
+```
+
+缺失的交叉边即隔离规则：Agent A 的本地注册不会进入 Agent B 的视图，父级的注册也不会仅因父级拥有子级的生命周期就进入子级。
+
+配套的[运行时设计 Agent Note](2026-07-12-agent-scope-runtime-design.md) 阐述了实现与正确性推理。[subagent 组合控制 Agent Note](../feature/2026-07-12-subagent-persona-tool-filter-and-depth.md) 负责独立的 `persona`、`toolFilter` 和 `maxDepth` 功能。
+
+### 注册来源决定可见性与清理
+
+通过普通插件上下文进行的注册是部署全局的，随该插件一起 dispose（资源释放）。同一方法通过 `agent.ctx` 调用则贡献给一个 agent，随该 agent 的作用域一起 dispose。
+
+| 注册来源 | 默认可见性 | 随谁 dispose |
+|---|---|---|
+| 普通插件上下文 | 每个符合条件的 agent 视图 | 注册插件 |
+| `agent.ctx` | 仅该 agent 的视图 | agent 作用域 |
+
+工具、提示词段落与变量、工具限制、守卫以及作用域事件监听器都遵循此契约。命名的本地值通常对该 agent 遮蔽同名全局值；各所属服务文档会说明例外与合并行为。
+
+普通贡献者的模式是在 agent setup 期间注册完整的本地世界：
+
+```js
+const handle = await ctx.agents.create({
+ sessionId: SessionId('reviewer'),
+ agentOptions: { model: 'model-name' },
+ setup(agentCtx) {
+ agentCtx.systemPrompt.section({
+ name: 'deployment:persona',
+ order: 0,
+ text: 'Review code, but do not modify files.',
+ })
+ agentCtx.tools.register({
+ name: 'review_summary',
+ description: 'Return the review summary.',
+ parameters: { type: 'object', properties: {} },
+ async execute() {
+ return [{ type: 'text', text: 'review complete' }]
+ },
+ })
+ },
+})
+
+ctx.tools.get('review_summary') // undefined: not global
+ctx.tools.get('review_summary', handle.agent) // the reviewer-local tool
+
+await handle.dispose()
+ctx.tools.get('review_summary', handle.agent) // undefined: scope is gone
+```
+
+setup 接收一个完整的受信 Cordis 上下文，因此可以组合普通插件和服务。其契约仅限组合：不支持通过 cast 或内部注册表调用来驱动或发布正在构建中的 agent。
+
+### 操作选择视图
+
+注册来源与操作主体是两个独立的事实。通过 `agent.ctx` 调用服务决定的是新注册归属何处，并不将后续读取绑定到该 agent。
+
+工具查找与执行接收其所服务的 agent。提示词组装接收正在构建请求的 agent 的组装上下文。事件分发接收其领域主体。这使共享服务实例可在多个 agent 间复用，同时让每个操作的视图保持显式。
+
+只有采纳了作用域契约的服务才会解析 agent 层。`agent.ctx` 不会自动改变任意 Cordis 服务调用的行为。
+
+### 作用域事件将路由与事件数据分离
+
+关于 Agent A 的事件通常到达无作用域监听器和 A 作用域监听器，而不到达 B 作用域监听器。没有 agent 主体的事件仅到达无作用域监听器。
+
+在 Cordis 层面，`Scoped<T>` 是一个不透明的路由接收器。它携带用于选择监听器的过滤器，但本身不是领域对象。因此事件签名将真实的 `Agent`、工具执行、审批请求或其他主体作为显式参数保留，供监听器检查。
+
+以 `{ global: true }` 注册的监听器有意绕过上下文受众过滤，但其清理仍跟随注册上下文。注册表成员变更通知保持不过滤，因为它们描述的是共享注册表状态而非某个 agent 的操作。生成的[事件目录](../../../../docs/cordis-catalog/events.md)是详尽的事件参考。
+
+### 创建最后发布，dispose 最后撤销
+
+`ctx.agents.create()` 和 `resume()` 构建未发布的会话、作用域、agent 和驱动器。它们等待 `setup`，准入最终的会话和 agent 条目，按序公告，启动循环，然后才返回 handle。
+
+可选的创建信号仅在创建或恢复挂起期间取消工作。promise resolve 后，返回的 `AgentHandle` 拥有显式 dispose 权。
+
+如果加载、setup、准入或发布失败，私有事务回滚其准备的一切。使用同一个调用方提供的存活 ID 的并发操作可能都到达 setup，但最终注册表条目只准入一个；每个失败者拒绝并清理其私有资源。在等待 dispose 完成后的顺序复用仍然有效。
+
+`AgentHandle.dispose()` 反转边界。它停用创建或驱动，等待同步发布解除，停止并排空驱动器和最终会话刷写，分离 agent 和会话，最后 dispose 作用域。重复或竞争的 dispose 请求合并为一个完成 promise。
+
+调用方的 Cordis 上下文和具体的 AgentLoop 工厂是结构性共同所有者。卸载任一方都会 dispose 事务或存活 agent。
+
+```mermaid
+flowchart TB
+ request["Create or resume"] --> privateWorld["Build private session, scope, agent, and driver"]
+ privateWorld --> setup["Await composition through agent.ctx"]
+ setup --> admission["Admit final session and agent entries"]

+ live -->|"handle or owner disposal"| quiesce["Stop and drain work"]
+ rollback --> quiesce
+ quiesce --> detach["Detach agent, then session"]
+ detach --> revoke["Dispose the agent scope"]
+```
+
+## 安全与权限是非目标
+
+agent 作用域组合的是受信的同进程注册。它不沙箱化插件、不定义父到子的权限格、不在创建时冻结授权、也不保证子级不能做超出父级的事。
+
+父级可以拥有一个可见工具比自身更广的子级，因为生命周期所有权不赠予也不限制注册。持有 Cordis 上下文的插件同样运行在同一进程中，可以直接调用可用服务。
+
+需要非升权保证的部署需要独立的权限表示、传播规则和执行检查。父级子集授权、创建时授权快照、显式未来授权 API，以及通用的能力/输出/终止标签均不在本决策范围内。
+
+## 曾考虑的替代方案
+
+被否决的设计要么将可见性与清理分离，要么只覆盖一类注册，要么重复共享基础设施，要么将生命周期所有权与继承混为一谈。
+
+### 向每个注册传递 agent 选项
+
+类似 `tools.register(definition, { agent })` 的 API 在每个注册表中重复作用域管道，且允许可见性所有权与清理所有权漂移。通过 `agent.ctx` 注册使两个事实跟随同一个 Cordis effect owner。
+
+### 过滤事件但保持注册表全局
+
+监听器过滤可以阻止错误的钩子运行，但无法限定工具 schema、可执行查找、提示词段落、变量或其他已注册数据的作用域。agent 本地组合仍需临时的全局变更。
+
+### 为每个 agent 创建独立的服务图
+
+所需的视图是共享部署服务加上一个本地注册层。每 agent 一个图会重复适配器，并使共享持久化、提供方注册表和应用启动复杂化。
+
+### 继承父级注册作用域
+
+父子关系描述的是生命周期和对话谱系，而非通用合并策略。层级查找会让无关服务意外继承，且在没有独立权限模型的情况下无法定义安全性。
+
+## 后果
+
+贡献者使用一种熟悉的模式：通过插件上下文注册共享行为，通过 `agent.ctx` 注册本地行为，在操作中选择真实 agent，dispose 返回的 handle。从观察者角度看 setup 是原子的，拆除则保留本地行为直到工作停止。
+
+代价是显式的主体选择、异步的编程式创建，以及服务需要逐个采纳作用域。扁平注册作用域有意不等同于权限，subagent 组合控制作为独立功能存在，而非隐藏的作用域语义。

Whether to serve is decided by `cordis.yml`; a yml that does not mount it is a legitimate process that does not serve. Protocol-level exit belongs to the plugin (after answering the `shutdown` request it disposes its own fiber, then `exit(0)`; an HMR-style unload only stops the service without exiting the process).

Its only dependency is app-boot. Process-level exit belongs to the bin (stdin EOF/SIGTERM → dispose then 0, SIGINT → 130).

+# Agent Note: Agent 作用域运行时设计与正确性
+
+Status: implemented
+
+[English](2026-07-12-agent-scope-runtime-design.md) | 中文
+
+## 问题
+
+[agent 作用域契约](2026-07-08-agent-scope-contexts.md)对贡献者而言很简单：通过 `agent.ctx` 注册，解析出一个全局加单 agent 的视图，仅在 setup 完成后发布，并保持作用域直到工作停止。运行时必须在协作式插件框架、异步创建、可重入监听器、持久化会话提交以及 worker 或进程故障等场景下维护这份契约。
+
+主要的设计风险是为每个竞态条件引入第二套机制。独立的预留、就绪哨兵、取消中继、快照层和保护注册表可能镜像同一个事实，直到没有读者能分辨哪个才是权威的。这些机制还会诱使运行时把可信的类型化调用当作敌对的序列化边界来处理。
+
+实现需要足够的状态来维护真实的所有权和结算边界，但不能更多。正确性审查者必须能够从接受、发布到拆除，沿着一条事实链跟踪下去，而无需在并行的表示之间做调和。
+
+## 决策
+
+运行时对每个独立事实使用一种机制。作用域路由有一个不透明载体与共享 layer store；每个活跃的注册表对象有一条注册表条目；每个创建或恢复操作有一个事务；类型化的同进程调用借用 readonly 值；真实数据边界只物化一次；协作式提示词组装的结果即为权威；worker/进程代码仅在不同所有者确实可能竞争时才保留独立的终止态和完全停稳态。
+
+该设计可概括为七项选择：
+
+| 问题 | 权威机制 |
+|---|---|
+| 选择全局加某个 agent 的注册 | 不透明作用域键、路由载体与共享 layer store |
+| 拥有一个活跃的 agent 或会话 | 由其 disposer 捕获的单条注册表条目 |
+| 协调创建/恢复 | 单个 `AgentCreationTransaction` |
+| 保护持久化、队列、模型或协议格式数据 | 在该边界处一次性物化 |
+| 在同一进程内传递类型化值 | Readonly 借用契约 |
+| 组合模型可见的提示词与工具表面 | 单个共享工具视图加权威的 assembly-waterfall 结果 |
+| 协调 subagent、worker 和进程关闭 | 单个取消信号加该边界独立的终止态/完全停稳态事实 |
+
+本 Agent Note 余下部分按依赖顺序展开这些选择：Cordis 机制、作用域路由、创建与会话提交、工具与提示词、subagent 与工作流，最后是可执行检查。
+
+[7 月 8 日 Agent Note](2026-07-08-agent-scope-contexts.md)仍然是贡献者契约。独立的 [subagent 组合控制 Agent Note](../feature/2026-07-12-subagent-persona-tool-filter-and-depth.md)拥有 `persona`、`toolFilter` 和 `maxDepth`；本文仅讨论它们的 setup 如何融入生命周期。
+
+## Cordis 模型：上下文、fiber、effect、receiver 与 waterfall
+
+理解实现需要五个 Cordis 概念。上下文选择服务和注册所有权；fiber 是一个活跃的插件或子生命周期；effect 将清理逻辑附加到 fiber；事件接收器选择监听器；waterfall（瀑布式事件）让监听器按顺序变换或否决一个操作。
+
+### 上下文是贯穿单个服务图的所有权路径
+
+所有 agent 共享一个 Cordis 服务图。派生的上下文不会克隆 `ToolRegistry`、`SystemPrompt`、持久化或模型适配器；它改变的是：通过该上下文进行的注册如何被标记，以及哪些 effect 拥有其清理逻辑。
+
+`agent.ctx` 就是这样一个派生上下文。服务调用仍然到达共享实例，而注册操作可以检查其调用上下文并将贡献存储在最近的作用域键下。普通的插件上下文不携带作用域键，因此注册到全局。
+
+### Fiber 与 effect 使清理成为结构性的
+
+Cordis fiber 是插件或子上下文被激活时创建的活跃实例。其状态记录该生命周期是 active、unloading、failed 还是 disposed。`ctx.effect()` 和 `ctx.on()` 返回 disposer，同时将这些 disposer 附加到注册所在的 fiber，因此卸载一个插件或 agent 作用域会移除通过该上下文注册的一切，无需单独的清单。
+
+vendor 中的 Cordis fiber 实现在任意 setup 或 `internal/plugin` 观察者运行之前就建立了所有权。可重入的卸载可以看到已启动的子 fiber 或 effect，拒绝卸载开始后添加的 effect，并通过一个公开的一次性 disposer 加入已启动的清理。拆除观察者被逐个隔离，因此一个回调无法阻止结构性清理。
+
+这些是框架生命周期保证，而非 agent 特有的策略。Agent 创建依赖它们，因为 setup 可以激活任意插件并同步重入所有者的 dispose。
+
+### Receiver 路由监听器；waterfall 组合决策
+
+Cordis 使用 dispatch receiver（`this`）过滤监听器，而 harness 的监听器需要一个显式的 agent、execution、request 或其他主体。`Scoped<T>` 标记作用域事件声明所期望的 receiver，但运行时载体刻意不暴露主体 API。
+
+因此，产品辅助函数构造载体并单独传递领域主体。这防止监听器路由变成另一套对象模型，并使事件签名在不了解载体内部的情况下也可理解。
+
+Cordis waterfall 是中间件风格的 dispatch。每个监听器接收 `next()`：调用它则委托给剩余监听器和基础操作，不调用则否决或替换下游结果。Waterfall 驱动提示词组装和工具策略；普通 emit 事件同步通知，parallel 事件等待所有监听器但没有否决结果。
+
+## 作用域路由：一个不透明键选择一层
+
+scope 包实现了 Cordis 路由所需的最小对象。其载体仅持有一个组合的服务过滤器和作用域谓词，而包私有地记录不透明键，并单独暴露会等待作用域 fiber 完全停稳的 disposer。
+
+### 作用域标识使用对象标识
+
+`ScopeKey` 是一个按标识比较的不透明对象。Harness 使用活跃的 `Agent` 作为自身的键，但该原语与领域无关，支持其他作用域所有者。
+
+`createScope(parent, key)` 返回一个作用域，其 `ctx` 共享父级的服务，其 effect 被标记为该键。`scopeOf(ctx)` 读取最近的注册键。`scopeTarget(base, key)` 创建事件接收器，其过滤器保留 base receiver 的 Cordis 服务过滤器，然后接纳无作用域的监听器和具有该确切键的监听器。
+
+Receiver 是一个小型载体而非领域对象的透明代理。需要 agent 的代码接收显式的事件参数；需要注册所有权的代码接收 `agent.ctx`。
+
+### 注册表读取叠加一个精确 layer
+
+作用域感知的注册表使用 `ScopedLayers`，拥有一个即时创建的全局 aggregate 和按标识键惰性创建的 aggregate。读取解析全局 layer 和至多一个精确局部 layer；它不创建状态，也从不遍历父级链。注册可见性与 Cordis effect 所有权都从同一个上下文派生，而回收会等待具体 layer 的完整 aggregate 变空（见[决策](2026-07-12-scoped-layers-store.md)）。
+
+每个服务保留其领域规则。命名 command 和提示词视图使用共享的、保持插入顺序的 shadow 合并；工具保留更丰富的 resolver，因为限制会在加入局部工具前过滤全局工具，保留的 Code Mode transport 则单独插入。提示词变量和工具 guard 保持实时迭代，而工具提供方成员关系按每次 assembly 物化。Scope 提供存储生命周期和命名遮蔽，而非通用的注册表视图。
+
+### 融合 dispatch 辅助函数防止主体漂移
+
+`agentEvents(context, agent)` 构造 agent 的载体并注入同一个 agent 作为事件主体。会话、工具、approval、提示词和 subagent 服务同样从它们已拥有的对象派生路由，而非接受一个无关的键。
+
+类型标记拒绝普通的裸 receiver 误用，开发环境不变式覆盖直接 JavaScript 或强制转换的 dispatch。主体保持显式，因为路由正确性和有用的事件数据是不同的关注点。
+
+## Agent 创建：一个事务拥有完整操作
+
+创建和恢复是一个具有多个阶段的异步生命周期，而非多个生命周期。`AgentCreationTransaction` 拥有调用方和工厂的活跃性、可选取消、私有资源、发布、回滚，以及每个所有者观察到的记忆化拆除。
+
+### 注册表条目是唯一的活跃标识记录
+
+AgentRegistry 和 SessionStore 各为每个活跃对象保留一条注册表条目。注册表条目持有稳定 ID、对象、作用域载体，以及属于该对象的少量发布或追加状态。
+
+detach 闭包捕获其确切注册表条目。它仅在映射仍指向该注册表条目时才删除，因此旧的 disposer 无法删除一个复用相同 ID 的后续对象。注册表不会重读可变的调用方对象来决定标识。
+
+没有预留 API。调用方提供的 ID 在最终写入注册表时被接纳。并发的同 ID 操作可能都完成私有 setup；恰好一个最终 `enter()` 成功，每个失败者回滚其私有资源。前一个 disposer 达到完全停稳态后，顺序复用即为有效。
+
+### 事务在等待之前就拥有准备工作
+
+事务在持久化加载或 setup 可能挂起之前，就被安装到调用方的 Cordis 上下文和具体的 AgentLoop 工厂下。它还在公开操作结算之前观察可选的创建/恢复信号。
+
+创建准备一个新 Session。恢复加载并验证持久化的 Session，然后准备相同的活跃会话标识。两条路径随后构建作用域、agent 和 driver，并调用相同的 setup/发布算法。
+
+工厂存储具体的 trace 目标，但通过调用方绑定的 Cordis trace 调用它们。这保留了依赖来源和调用方所有权，而不堆叠 trace 代理。
+
+### Setup 是私有世界内的可信组合
+
+Setup 接收完整的子上下文，可以等待插件激活。它可以注册工具、提示词段、限制、监听器和其他 effect，但公开契约不支持通过强制转换或内部注册表调用来驱动或发布正在创建中的 agent。
+
+事务将异步加载和 setup 与停用进行竞争，而非无限等待外部代码拥有的 promise。如果取消或所有者卸载获胜，即使外部 promise 永不结算，公开创建也会在事务拥有的清理之后拒绝。
+
+### 发布有一条有序的提交路径
+
+发布按观察者所需的顺序接纳和宣告资源：
+
+1. 将会话写入注册表。
+2. 将 agent 写入注册表。
+3. 宣告 `session/created`。
+4. 宣告 `agent/created`。
+5. 启用公开驱动。
+6. 发射 `agent/session-start`。
+7. 启动 driver。
+
+Agent 在两个注册表和创建通知都达成一致之前绝不驱动。同步监听器可以否决或 dispose 一个所有者；事务记录发布进行中，并等待该回调栈展开后再继续拆除。每个已开始的创建宣告在回滚期间都有匹配的销毁宣告。
+
+以下序列图隔离了非显而易见的竞态：同步创建监听器可以在发布调用栈仍拥有两个注册表条目时请求 dispose。拆除必须立即停用，但要等待该栈展开后才停止和分离任何东西。
+
+```mermaid
+sequenceDiagram
+ participant Tx as AgentCreationTransaction
+ participant Registries
+ participant Listener as Synchronous listener
+ participant Driver
+
+ Tx->>Tx: mark publication in progress
+ Tx->>Registries: announce agent/created
+ Registries->>Listener: invoke inside the same call stack
+ Listener->>Tx: dispose reentrantly
+ Tx->>Tx: deactivate, teardown waits for publication
+ Tx-->>Listener: disposal request accepted
+ Listener-->>Registries: return
+ Registries-->>Tx: announcement unwound
+ Tx->>Tx: resolve publication settlement
+ Tx->>Driver: stop and drain
+ Tx->>Registries: detach agent, then session
+ Tx->>Tx: dispose scope and resolve teardown
+```
+
+### 拆除在撤销注册之前保留工作
+
+每个拆除请求加入一条记忆化路径。顺序为：
+
+1. 停用创建或驱动，让同步发布完成。
+2. 停止并排空 driver，包括空闲注入刷新。
+3. 分离 agent。
+4. 分离会话。
+5. Dispose agent 作用域。
+6. 退役事务所有权追踪。
+
+此顺序让最终的 agent 和会话事件能使用匹配的作用域监听器，并使持久化观察者在最终刷新完成前保持附加。作用域 dispose 放在最后，因为注册撤销是外部可见的生命期边界。
+
+## 会话追加：物化、验证、提交、通知
+
+会话事件跨越持久化边界，因此追加操作拥有其数据。算法的其余部分使用一条已附加的注册表条目和一个提交点。
+
+### 持久化数据一次性物化
+
+Session 头部、种子和追加的事件是无损 JSON 数据。Session 构造函数或追加路径在存储前物化并验证它们，并暴露冻结的快照，因此后续调用方的修改无法改变持久化、回放或模型重建。
+
+这是一个真实的所有权边界：值离开调用方，可能被持久化，且必须在之后重建相同的请求。这比类型化的同进程回调或注册表定义有意更严格。
+
+### 提交前监听器可以否决；提交后观察者不能
+
+追加遵循一个序列：
+
+1. 物化持久化事件和表面意图。
+2. 取得 SessionEntry 的独占所有权，并拒绝该注册表条目上的重入追加。
+3. 解析作用域回调并运行内部不变式验证。
+4. 恰好推送一次；这是提交点。
+5. 逐个通知每个观察者，隔离同步和异步失败。
+6. 释放追加状态并兑现发布期间请求的 detach。
+
+没有观察者错误能让已提交的事件看起来未提交，一个坏的监听器也无法饿死后续监听器。Session 不变式在提交前暂存其转换，仅当同一事件到达被隔离的提交后观察者时才应用。
+
+`flush()` 启动每个持久化监听器并等待所有结果后再报告失败。这种有意的 all-settled 行为防止同步失败饿死另一个后端或最终刷新。
+
+## 信任边界：仅在所有权真正变更时复制
+
+运行时区分类型化的进程内契约与序列化及持久化边界。这是值和回调的主要简化规则。
+
+| 边界 | 所有权规则 |
+|---|---|
+| 同进程内的类型化服务/插件调用 | 借用 readonly 值和回调 |
+| 解析的插件配置或外部文件 | 验证语义和结构输入 |
+| 队列中的收件箱消息 | 在异步消费前物化 |
+| 模型/工具 JSON 输入或输出 | 在模型/工具边界处物化 |
+| 持久化会话或持久化数据 | 在提交前物化并验证 |
+| Worker、进程或协议格式消息 | 序列化、验证并拥有解码后的值 |
+
+测试中构造恶意 getter、在交接后替换类型化回调、或强制转换伪造服务对象的做法本身不定义生产契约。运行时在数据跨越解析器、队列、模型、持久化、文件、worker、进程或协议格式（wire format）边界时保留检查，并在可信进程内依赖 readonly 类型加插件纪律。
+
+回调隔离与数据所有权是分开的。监听器是任意扩展代码，即使其参数是可信的也可能抛出异常；发布和提交后路径仍按其事件契约隔离失败。
+
+## 工具与提示词：单一视图、权威组装、已提交的结果
+
+工具展示和执行共享一个私有解析器。提示词组装仍然是可信的协作式组合：注册表提供有序输入，assembly waterfall 的返回值就是 agent loop（智能体循环）记录和发送的内容。执行仅在策略或结果结算必须单调时才使用独立的单向边界。
+
+### 一个解析器定义工具视图
+
+私有解析器应用当前展示模式、活跃的全局限制、精确的局部叠加和局部遮蔽。Schema、查找、执行、Code Mode SDK 生成和限制验证都使用该解析器或其限制前的全局名称视图。
+
+[subagent 组合控制 Agent Note](../feature/2026-07-12-subagent-persona-tool-filter-and-depth.md#tool-filtering-is-one-live-global-view-rule)拥有用户可见的 allow/deny 语义。实现要求是一致性：被过滤掉的全局工具不能通过另一条查找路径仍可执行，局部遮蔽的定义就是被展示和执行的同一个定义。
+
+`ToolRestriction` 接受 readonly 的 allow/deny 名称并将其编译为内部集合。多个限制取交集。公开的 `visible()` 和 `knownNames()` 方法是不必要的，因为只有注册表需要中间视图。
+
+### 工具执行拥有标识和边界物化
+
+注册表为每次执行分配一个新的带品牌的 `Symbol` token。嵌套的 Code Mode 调用将外层 token 作为 `parent` 携带，因此结构化输出可以通过标识将内层捕获与其外层 `run_code` 结果关联。
+
+注册表分配的新 Symbol 提供无碰撞的执行标识，无需 WeakSet 成员注册表。调用方无法通过 `ToolExecutionInput` 提供执行自身的 token；它们仅在注册表创建后接收流水线拥有的 `ToolExecution`。这是一个可信的类型化契约，而非针对任意强制转换或 JavaScript 调用方的运行时防御。
+
+参数在模型/工具 JSON 进入流水线时一次性物化。Pre-、around- 和 post-execute 监听器操作类型化的 execution 和决策。Call ID 关联、审批、单调守卫和 Code Mode 嵌套仍然是显式的关系检查。
+
+在 post-execute 或外层流水线完成规范化后，注册表先为候选结果创建无损快照，并将快照失败转为普通错误；随后调用在本次调用创建时已快照的可选 `ToolDefinition.finalizeContent` 回调，最后一次性物化并冻结被接受的最终结果。该回调只能替换内容，因此即使工具强制最后一道结果上限，结构化错误标识、上下文与元数据仍由注册表拥有。每个同步的 `tools/result` 观察者接收该确切的已提交对象，观察者失败被逐个隔离。外层流水线失败或候选快照失败会在最终内容处理之前被规范化，因此观察者可以丢弃针对同一权威边界的暂存工作。
+
+### Assembly waterfall 拥有最终的模型可见组合
+
+SystemPrompt 首先将全局加 agent 的段、变量和工具提供方解析为确定性的注册表贡献。作用域过滤的 `system-prompt/assemble` waterfall 随后可以重排、替换、添加或移除任何段、变量或 schema。其返回的组装结果即为权威；没有后续的恢复步骤，普通提示词段、工具定义或提供方结果上也没有终态元数据。
+
+这是一个可信的同进程扩展 seam，而非权限边界。修改 Code Mode 的 `run_code` schema 或 `tools:sdk` 指令，或结构化子级的捕获 schema 或指令的监听器，有责任在其返回的组装中保持协议的一致性。ToolRegistry 仍然保留 `run_code` 不受普通工具注册和限制影响，因为那些是注册表不变式，但 assembly 中间件仍然可以自由变换最终的模型可见表面。
+
+Scope 直接解决了真正的隔离问题。结构化输出贡献注册在子级的精确作用域中，而 Code Mode 从同一个已解析的工具视图派生其传输和 SDK。第二套命名保护系统需要另一套所有权和碰撞规则来覆盖任意 schema 提供方（包括有意贡献重复名称的提供方），却不创建新的信任边界。
+
+### 结构化输出仅提交权威结果
+
+结构化输出将子作用域组合与两阶段执行提交相结合。子级在发布前注册其 `structured_output` 工具和指令；可信的 assembly 监听器可以变换这些普通贡献，并有责任在期望子级完成时保持协议。工具体验证候选值并按当前 `ToolExecution` 暂存，但成功捕获仅由不可变的 `tools/result` 观察决定。
+
+对于原生调用，观察者仅在该确切执行的最终结果成功时才删除暂存并提交其值。因此 post-execute 阻止或外层流水线失败不会留下已捕获的值。
+
+对于 Code Mode SDK 调用，内层成功结果记录 `{ parentToken, value }` 而非提交。观察者等待 token 匹配 `parentToken` 的 `run_code` 执行，仅在该外层最终结果也成功时才提交。程序失败、运行时中止或外层 post-policy 拒绝会丢弃待定值。
+
+一旦值处于待定或已提交状态，作用域单调守卫拒绝后续工具调用。提交后，普通串行的 `agent/turn-stop` 监听器在 continuation 和 steering（中途引导）已折叠之后返回停止决策。Schema 验证失败仍然是普通的 `INVALID_ARGS` 工具错误，子级可以在同一轮次内重试。
+
+纯 Code Mode 的注册表贡献从原生 wire schema 中省略 `structured_output`，并通过生成的 SDK 暴露它。Assembly waterfall 可以有意改变该展示；执行仍然针对子作用域定义进行验证，监听器拥有其创建的任何替代模型可见路由的一致性。
+
+### 三个执行边界有意设为单向
+
+提示词组装有意是协作式的，但三个执行事实在其可扩展阶段之后需要单向结算：
+
+| 边界 | 最终权力 | 为何普通监听器顺序不够 |
+|---|---|---|
+| 工具 pre-policy | 单调拒绝 | 后续监听器不得重新允许已被拒绝的调用 |
+| 工具结果 | 观察不可变的已提交结果 | 结构化输出必须仅提交实际逃出流水线的结果 |
+| 轮次 continuation | 在普通 continuation 折叠之后停止 | 已提交的终端输出必须结束轮次 |
+
+`ToolGuard` 是单调策略注册表。已提交的工具观察是上述被隔离的 `tools/result` 点。终端结构化输出监听普通串行的 `agent/turn-stop` 折叠，在正常 continuation 和 steering 决策之后；类型化的监听器契约不需要公开的 `strictSerial()` dispatcher。
+
+### Skill 和 approval 服务信任类型化调用方
+
+Skill 注册表定义和 approval 策略是 readonly 的同进程契约。它们的服务不克隆回调对象，也不防御交接后的回调替换。
+
+Skill 仍然验证外部 skill 文件和解析的提供方输出，通过调用 agent 的工具视图路由目录，并精确 dispose 注册。Approval 仍然解析策略、观察取消、按 `request.agent` 路由 `approval/request`、记录持久化审计对，并隔离应答者和提交后观察者的失败。
+
+## Subagent：就绪即 start promise
+
+Subagent 启动有一次所有权转移。提供方拥有部分资源直到其 start promise 以一个就绪的已发布 run 兑现；调用方拥有返回的 run 并必须 dispose 它。
+
+### 服务契约有一个取消通道
+
+`SubagentProvider.start()` 和 `SubagentService.start()` 返回 `Promise<SubagentRun>`。Promise 仅在后端建立了它所承诺的子级之后才兑现，因此调用方和 `subagent/start` 观察者从不需要第二个 `run.started` 就绪 promise。
+
+`SubagentStartRequest.signal` 是必需的。中止它会在启动期间和就绪之后请求取消。`SubagentRun.dispose()` 也请求取消并等待完全停稳。没有单独的公开 `run.cancel()` 通道。
+
+可选的 `sendMessage()` 支持能接受 steering 的活跃后端。可选的 `resume()` 返回 `Promise<SubagentRun>`，因为恢复的子级有相同的异步就绪边界。
+
+服务在调用提供方之前验证提供方能力和请求语义。提供方拒绝在拒绝逃出之前清理所有部分资源，且不发射 `subagent/start`/`subagent/end` 对。兑现之后，服务附加结果观察、发射作用域 start 并返回 run。提供方移除阻止后续 start，但不撤销提供方已接受的 run。
+
+### 进程内提供方复用核心事务
+
+Spawn 和 fork 共享一个进程内 driver。它通过 `parent.ctx` 创建子级，将必需的 signal 传入核心创建事务，并在未发布的 setup 期间安装 persona、工具限制和结构化输出贡献。
+
+提供方等待创建并仅返回已发布的 run。在交接时，核心创建分离其仅用于创建的 abort 监听器；提供方在安装活跃 run 监听器之前立即重新检查 signal，因此在那个窄窗口中的 abort 会 dispose 新句柄而非逃脱取消。父级拆除跟随子级，因为操作属于 `parent.ctx`；提供方卸载阻止新 start 但不成为已接受 run 的第二个撤销所有者。Run disposer 取消子级并等待 AgentHandle 的有序拆除。
+
+Spawn 使用空会话种子。Fork 使用经验证的已完成轮次前缀。对话种子仅改变历史，不导入作用域、工具、服务或权限。
+
+### ACP 提供方拥有进程直到就绪或清理
+
+ACP 提供方跨越真实的进程和协议格式边界，因此它保留验证、环境清洗、消息序列化、abort/进程竞争，以及从 kill 到进程退出并完全停稳的过程。
+
+Start 仅在 `initialize` 和 `newSession` 成功后才 resolve。Abort、spawn 失败、RPC 失败或无效启动响应在拒绝前回收进程。就绪后，result 映射 ACP 提示词结果和流式输出；dispose 请求取消、关闭连接并通过一条记忆化路径等待进程退出。
+
+## 工作流与 ACP 进程：仅保留独立的异步事实
+
+Worker 和子进程桥接比同进程注册表需要更多状态，因为消息、进程死亡和清理可以独立结算。它们的状态围绕这些真实事实组织，而非重复的取消协议。
+
+### 工作流子级是待定 start 或已发布记录
+
+工作流宿主保持待定的提供方 start promise 和已发布的子级记录。子级仅在异步 `SubagentService.start()` 兑现时才从待定变为已发布；被拒绝的 start 清理其部分提供方工作且不产生子级生命周期对。
+
+一个宿主拥有的 AbortController 向待定和活跃子级提供必需的 signal。关闭工作流准入中止该 signal，因此没有重复的 `ChildCancel` worker RPC 或显式的宿主侧 `run.cancel()` 扇出。完全停稳需要等待待定 start 和已发布子级 dispose 两者。
+
+Worker 边界仍然序列化请求和结果。宿主保留首个终端结果仲裁、精确的子级计数、worker 死亡处理、优雅终止、迟到/重复消息拒绝和有界清理，因为结果接收、worker 退出和子级完全停稳是真正独立的事实。
+
+### 终端结果与物理清理保持分离
+
+工作流结果按公开优先级规则记录首个被接受的终端结果。该结果选定后清理可以继续：活跃子级仍需 dispose，worker 仍需终止，慢速外部后端可能超出配置的优雅期限。
+
+公开 dispose 在调用回调之前取得其记忆化 promise 的所有权。Worker 死亡在处理任何排队的迟到子级请求之前关闭准入，合成缺失的生命周期结束，并启动子级/进程清理而不重写已声明的结果。
+
+### ACP 提示词结算不依赖更新投递
+
+[仅面向自动化的 ACP 桥接层](../simplification/2026-07-23-acp-automation-only-protocol.md)直接将一个进行中的提示词与其观察到的用户消息轮次关联。它不从日志水位线扫描，也不使用会话状态作为第二个调和预言机。
+
+即使已提交消息的更新无法送达客户端，会话事件监听器也会从匹配的 `turn/end` 结算关联。因此更新投递不能让会话永久处于进行中状态。ACP 创建由服务器分配 id 的全新会话，并拥有由此产生的每个 agent 句柄，直到连接拆除。
+
+## 正确性强制
+
+该设计通过类型、运行时逃逸点、生成的契约和行为测试来强制执行。没有哪一层被要求证明它无法观察到的东西。
+
+### 类型使常规路径难以误用
+
+Readonly 契约描述借用的同进程值。`Scoped<T>` 标记事件接收器，`agentEvents()` 融合载体和主体，工具输入省略注册表拥有的 token，subagent 异步返回类型直接暴露就绪性。
+
+TypeScript 无法管控 JavaScript 强制转换、直接 Cordis dispatch、进程消息或持久化文件，因此运行时强制保留在这些逃逸点。
+
+### 运行时不变式覆盖跨服务事实
+
+`dsh-scope/invariant` 配套插件在被选用时验证每个声明的作用域事件使用带标记的载体，以及暴露主体的事件族使用匹配的键。独立的 `dsh-session/invariant` 贡献在追加提交前暂存 trace 验证，并在同一事件提交后推进；二者都通过 `ctx.invariants` 注册。
+
+该插件不通过扫描注册表来管控可信 setup，也不拒绝通过强制转换构造的提示词 assembly 对象。这些检查会将组合契约变成推测性的运行时机制，却不保护真实的外部边界。
+
+### 生成的产物使公开契约保持对齐
+
+事件目录、服务目录、生产者/消费方矩阵、配置目录、模块图、工具目录、type-equiv 块和作用域事件解析器映射都是从源码生成或受新鲜度门禁约束的。[TypeScript 语义门禁 Agent Note](../process/2026-07-14-typescript-program-backed-semantic-gates.md)拥有 Program 构造、语义事件发现和解析器生成规则。
+
+行为测试固定了作用域路由和 dispose、最终写入注册表时的碰撞清理、发布回滚、有序完全停稳、持久化前/后提交行为、跨展示和执行的活跃工具过滤、协作式提示词组装、原生和 Code Mode 中的结构化输出提交、异步 subagent 启动和信号取消、worker 终端仲裁、ACP 结算和进程拆除。
+
+## 曾考虑的替代方案
+
+[7 月 8 日 Agent Note](2026-07-08-agent-scope-contexts.md#alternatives-considered)拥有公开扁平作用域契约的替代方案。此处的替代方案关注实现形态。
+
+### 使用透明代理作为作用域载体
+
+模拟主体的代理必须保持属性、可调用、可构造、私有字段、描述符和代理不变式行为，而监听器路由从不需要这些。一个小型不透明载体保持过滤器和键，而显式事件参数携带主体。
+
+### 在 setup 前预留 agent 和会话 ID
+
+预留防止重复的私有 setup 工作，但需要跨服务能力、释放排序、废弃预留清理和已准备对象绑定。ID 由调用方提供，并发复用是调用方错误；最终写入注册表时可以选择赢家，而失败的事务干净地回滚。
+
+### 对每个类型化的同进程参数做快照
+
+通用复制防御有状态 getter 和违反 readonly 契约的调用方，但增加分配、重复验证器和可能遗忘复制的路径。物化属于解析器、队列、模型、持久化、worker、进程和协议格式边界——即所有权真正变更的地方。
+
+### 为就绪、取消和 dispose 提供独立控制器
+
+并行哨兵可能都镜像一个操作是否活跃。一个事务或 start promise 拥有操作；独立 promise 仅在发布展开、外部工作、终端结果和物理层面的完全停稳可以独立结算时才保留。
+
+### 保留同步 subagent start 加 `run.started`
+
+这将提供方接受与就绪分离，迫使每个消费方注册部分 run、附加结果观察、等待就绪并清理就绪失败。异步 start promise 使提供方到调用方的所有权转移本身成为就绪边界。
+
+### 在 assembly 之后恢复选定的提示词或工具贡献
+
+Waterfall 之后的恢复步骤会在文档化的协作式 seam 之后创建第二套组合规则。正确分配规范的存在或缺失还需要为任意工具 schema 提供方制定所有权和碰撞规则，而这些提供方的普通输出可能包含重复名称。作用域注册已经提供了所需的按 agent 隔离，可信的 assembly 监听器拥有其返回内容的协议一致性，因此命名恢复增加了机制却不建立独立边界。
+
+### 用同进程加固替代 worker/进程生命周期守卫
+
+Worker 消息、进程死亡和持久化输入确实跨越所有权和序列化边界。首个结果仲裁、验证、环境清洗和使进程完全停稳的清理即使在敌对的同进程回调机制不存在时仍然必要。
+
+## 后果
+
+实现更小，其证明与所有权图具有相同的形状。一个键选择一层，一条注册表条目拥有一个活跃注册表对象，一个事务拥有创建，一个解析器拥有工具视图，一个异步 promise 转移 subagent 所有权。
+
+### 设计保证的内容
+
+- 作用域贡献仅在其精确的 agent 视图中可见，并随该作用域一起 dispose。
+- 创建和恢复不暴露部分配置的句柄；最终写入注册表时的失败者和发布失败清理每个已准备的资源。
+- Dispose 在 driver 排空和最终会话工作期间保留作用域监听器和持久化，然后撤销作用域。
+- 持久化、队列、模型、worker、进程和协议格式的值在其真实边界处被拥有；类型化的同进程值遵循 readonly 契约。
+- ToolRegistry 的展示、查找和执行在专家 assembly 变换之前解析相同的活跃视图，已提交的结果有一个不可变的观察点。
+- 注册表贡献是确定性输入，而可信的 assembly waterfall 拥有最终的模型可见组合。
+- Subagent start 仅返回就绪的 run，必需的 signal 取消待定或活跃的工作，dispose 到达后端的完全停稳契约。
+- Worker/进程结果优先级和清理在死亡、迟到消息和有界拆除下保持正确。
+
+### 代价与局限
+
+作用域感知服务仍然维护全局和按标识键索引的映射，操作必须显式携带其真实 agent。异步创建/恢复和 subagent start 要求调用方等待所有权转移并 dispose 返回的句柄。
+
+可信的 `system-prompt/assemble` 监听器可以移除或替换 Code Mode 和结构化输出协议片段。这是有意为之：监听器拥有最终组合，必须保持部署期望仍可用的任何协议。
+
+该设计信任同进程中的类型化插件。它不防御任意强制转换、有状态 getter、违反 readonly 契约的修改，或插件有意在支持的组合 API 之外使用环境服务访问。
+
+[安全与权限非目标](2026-07-08-agent-scope-contexts.md#security-and-authority-are-non-goals)仍然是根本性的。这些机制证明注册组合、发布和生命期所有权；它们不证明隔离或父到子的非升权。

## Problem
Provider-routed adapters let every request choose `provider + model`, but `LlmService` exposed only routing and streaming. A UI could not discover which providers were registered or which models an adapter was prepared to recommend. ACP clients therefore received no `model` session config option, so Zed, JetBrains, and VS Code integrations had no model list even though the request seam already supported runtime switching.
@@ -24,21 +26,17 @@ Catalog membership is advisory. It drives selectors and diagnostics but never ch
`dsh-llm-pi-ai` maps the configured provider's installed `getModels(provider)` entries into the neutral catalog. Its existing request-time catalog lookup remains authoritative and still rejects unknown models with `UNKNOWN_MODEL`. `dsh-llm-deepseek` accepts an optional `models` config containing display entries, defaulting to `deepseek-v4-flash` named `DeepSeek-V4-Flash` and `deepseek-v4-pro` named `DeepSeek-V4-Pro`. An explicit list replaces those defaults and an empty list disables discovery. The entries improve selector UX for known public or private models, while every unlisted model id continues to pass through unchanged.
-### ACP session config option
+### Per-session selection in the front door
-The ACP bridge advertises one select with `id: model` and `category: model` in `session/new` and `session/load` when the session has a complete target whose provider is registered. Each opaque option value encodes the full provider/model pair. Models are grouped by provider when multiple non-empty provider groups exist; a single group is flattened for clients that render simple selects better.
+A selection is owned by the front door that offers it (today the TUI `/model` selector), never by `LlmService` or `AgentOptions`: those are deployment-wide or creation-wide objects, and mutating them would couple concurrent sessions. Each opaque choice carries the full provider/model pair, because the same model id may appear under multiple routes.
-The session's current target is added to the displayed options when its adapter omits it. This preserves custom DeepSeek and private-endpoint models while keeping the adapter catalog advisory. A target with an unregistered provider is not advertised, and a model-less agent remains available to another `agent/request` supplier.
-
-`session/set_config_option` accepts only values from the current catalog snapshot and updates a target reference owned by that ACP session. No global `LlmService` or `AgentOptions` state changes, so concurrent sessions may select different providers and models. The existing permission select remains independent, and every response returns the complete refreshed option state.
+The ACP automation transport is not a catalog consumer. Its deployment config supplies one optional provider/model target for newly created agents, and it advertises no model selector or configuration-option interface.
### Prompt/request consistency and durability
-Agent setup installs scoped `system-prompt/assemble` and `agent/request` listeners. Prompt assembly snapshots the selected pair once per step, overwrites the assembled `provider` and `model` variables after downstream prompt listeners, and the request listener applies that same snapshot after downstream request listeners. A selection during asynchronous assembly therefore starts on the next step rather than splitting prompt text from routing. Other call-config fields remain untouched.

A selection during asynchronous assembly therefore starts on the next step rather than splitting prompt text from routing. Other call-config fields remain untouched.
-The request header remains the durable source of truth. When a selected target is actually used, the existing full `request/header` snapshot records it. `session/load` initializes the ACP selection from the folded last request header before falling back to bridge config. A selection that is never used by a request is intentionally in-memory only because it never became model-visible state.

-ACP's experimental `providers/*` capability is not used. That draft surface configures provider base URLs, protocols, and headers, including secrets; it does not enumerate models and would give the UI authority to rewrite deployment-owned adapter configuration.

## Consequences
- Any adapter can expose a dynamic model list without leaking provider-library types into the core seam.
- Catalog consumers must treat absence as “not advertised,” never “invalid request.”
-- pi-ai-backed ACP deployments automatically inherit the installed pi-ai provider catalogs; hand-written DeepSeek deployments list known choices explicitly and retain arbitrary model support.
-- ACP clients receive a standard stable model config option, with provider-aware values and per-session isolation.
+- pi-ai adapters expose their installed provider catalogs; hand-written DeepSeek deployments list known choices explicitly and retain arbitrary model support.
+- Human-facing catalog consumers own their selection interaction. ACP uses its fixed deployment target and does not widen the protocol with model discovery.
- Request headers remain compatible with the provider-routed session shape; no new JSONL event or format version is required.
-- A catalog read can be asynchronous. ACP reads a detached snapshot before creating or resuming an agent, so discovery failure cannot leave a partially published session.
+- A catalog read can be asynchronous, and every caller receives detached values.
## Testing
-Unit coverage validates catalog detachment and malformed metadata, pi-ai and DeepSeek catalog projection, ACP provider grouping, custom-current insertion, invalid values, provider/model request routing, prompt-variable alignment, concurrent-session isolation, model-less fallback, and load restoration from the request header. The existing ACP transport suites verify that the additional config option does not change prompt, cancellation, replay, approval, or tool-rendering behavior.
+Unit coverage validates catalog detachment and malformed metadata, pi-ai and DeepSeek catalog projection, provider/model request routing, and prompt-variable alignment; per-agent isolation follows from installing the listeners on the agent-scoped context.

+# Agent Note: Unify agent delivery and coalesce injected context into user/message
+
+Status: implemented
+
+English | [中文](2026-07-22-unified-send-and-coalesced-user-messages.zh.md)
+
+## Problem
+
+The agent's public driving surface had grown three near-parallel verbs — `send`, `steer`, `inject` — each with its own options type, its own live event story, and its own durable event. `send` and `steer` both queued a frozen inbox record and emitted `agent/queued`; `inject` bypassed the inbox and wrote a separate `context/message` durable event. The three verbs actually vary along only two independent axes: which queue an item joins (a whole new turn versus the active turn) and whether the item makes the model run. Encoding that 2×2 as three hand-written methods hid the symmetry, made "queue a turn without waking the driver" unreachable, and left `cancel()` with no way to abort a turn while preserving queued work.
+
+Separately, `context/message` and `user/message` had converged: the surface projected both as verbatim user-role content, and the only real difference was that injected context carried `source`/`meta` and was "not a prompt." Two event types for one projection meant every consumer branched on event type to answer "is this a human prompt?", and the goal system used the type split as a side channel (round-zero state changes were `context/message`, admitted rounds were `user/message`).
+
+## Decision
+
+**One acceptance mechanism, four intent helpers.** The concrete loop resolves `followup`, `queue`, `steer`, and `inject` into one (`target` × `wakeup`) acceptance mechanism. `followup` is `next-turn`/wakeup, `queue` is `next-turn`/no-wakeup, `steer` is `next-step`/wakeup, and `inject` is `next-step`/no-wakeup. The public structural interface exposes that mechanism as `send(ResolvedAgentInput)` for callers that already have fully resolved routing; every field is mandatory, and the discriminated input type excludes attached contexts from injection. The [intent-named delivery decision](2026-07-24-intent-named-agent-delivery.md) owns that superseding interface choice. Internally, `wakeup` means “make the model run”: wake a parked driver for an ordinary item or force a continuation for running steering.
+
+**inject keeps its mechanism.** `inject` appends durable model-facing context at the current log position (deferred behind an executing tool batch), or opens a one-shot `injection` turn when idle. It bypasses the FIFOs entirely, accepts no attached contexts, and defaults its source to `{ kind: 'plugin', plugin: '' }`, never `{ kind: 'user' }`.
+
+**context/message is gone.** Injected context is now a `user/message` whose `source` is a non-`user` kind (plugin or goal). `PromptMessageData` gained the optional `meta` that `context/message` carried. The surface, derivation, and `SurfaceEventType` drop `context/message`; consumers that need "is this a human prompt?" read `source.kind === 'user'` instead of the event type. This keeps goal-authority's human-authority check exactly as strict as before — an injected message defaults to a plugin source and can never satisfy `source.kind === 'user'`.
+
+**Goal replay disambiguates by round, not type.** A goal state change is a round-zero goal-sourced `user/message` carrying `goal/change` metadata; a positive round is an admitted continuation prompt. `decodeGoalEvent` now takes a `user/message` and still fails loud on goal metadata under a non-goal source or a goal source lacking metadata.
+
+**Delivery returns an id.** Each delivery method returns an opaque branded `AgentMessageId` for the accepted input. FIFO methods carry it through their inbox lifecycle events; injection bypasses those events.
+
+**Three inbox events replace agent/queued.** `agent/inbox/enqueue` (an item entered a FIFO), `agent/inbox/dequeue` (the driver claimed one), and `agent/inbox/discard` (`cancel()` dropped pending items) each carry an `AgentMessage` — the accepted message including its returned `id`, steering/wakeup facts, source, and contexts — so a caller can correlate a queued item with its lifecycle. Injection never touches a FIFO and emits none of these. Every FIFO entry publishes an enqueue, including the loop-authored continuation-reason steer (`agent/turn-continuation` returning `{ action: 'continue', reason }`), so the ledger stays balanced with its later dequeue or discard. The `dsh-agent` invariant companion asserts FIFO conservation: a per-agent outstanding count that dequeue and discard can never drive negative.
+
+**cancel gains keepInbox.** `cancel(cause?, { keepInbox? })`; when true it aborts the active turn but preserves queued and steering items (no discard event, and un-started work is not dropped).
+
+## Alternatives considered
+
+- **A dedicated `MessageSource` kind `context`** for injected content. Rejected because `plugin` already means "not a human," so a fourth kind would add a parallel axis the authority checks would have to learn. Injected context defaults to a plugin source instead.
+- **A typed discriminant field on `PromptMessageData`** (e.g. `origin: 'prompt' | 'context'`) to replace the event-type split. Rejected in favor of `source`, which every consumer already carries and which the goal system already keyed on; a second discriminant would duplicate that fact.
+- **Keeping `agent/queued` alongside the inbox events.** Rejected as a mirror: `agent/inbox/enqueue` is the same enqueue-time signal with the accepted routing facts, and the dequeue/discard events complete the FIFO lifecycle the single event could not describe.
+
+## Consequences
+
+The concrete driver has one delivery mechanism. Four common helpers hide its (`target` × `wakeup`) matrix behind caller intent, while `send` exposes the fully resolved matrix for advanced callers. One durable message type serves prompts, injected context, and goal rounds, so the surface projection and every “human prompt?” check simplify to a `source` test. The goal fold's channel split moves from event type to `source.round`, and every consumer that filtered `context/message` filters `user/message` by source. The turn-enclosure and reconstruction invariants are unchanged: an idle injection still wraps a one-shot turn, now emitting `user/message` instead of `context/message`.
+
+Internally, `wakeup` is the “should the model run” signal, so the inbox distinguishes `hasWakingQueued` (drives the loop and idle/quiescence decisions) from `hasQueued` (anything to dequeue): a lone `queue()` item stays parked at idle and rides along the next waking follow-up, and `whenIdle`/`cancel` settle quiescence off the waking signal (a lone quiet item takes `whenIdle`'s fast path, so no waiter is left hanging). `SendOptions.meta` on a queued or steering message is carried onto the durable `user/message`/`steering/message`, matching injection; it is intentionally absent from the live `AgentMessage`, which carries only routing facts. Every enqueued id gets exactly one terminal lifecycle event: a terminal stop that drops pending steering emits `agent/inbox/discard` both at the in-turn stop point and on the post-turn drain of late steering, and disposal discards any still-pending items before the loop exits. The `agent/inbox/*` payload is frozen so a listener cannot mutate the shared correlation object mid-dispatch, and a loop-authored continuation reason is snapshotted and frozen like public steering. Injection validates its payload before opening an idle one-shot turn; `InjectOptions` omits attached contexts, while the non-waking next-step variant of `ResolvedAgentInput` requires an empty context tuple.

+# Agent Note: 统一 agent 投递并把注入的上下文合并进 user/message

+## 问题
+
+agent 的对外驱动接口逐渐长出三个近乎平行的动词——`send`、`steer`、`inject`——各自带有独立的选项类型、独立的实时事件叙事，以及独立的持久事件。`send` 和 `steer` 都会把一条冻结的 inbox 记录入队并发出 `agent/queued`；`inject` 则绕过 inbox，写入一条独立的 `context/message` 持久事件。这三个动词实际上只沿两条独立的轴变化：一个队列项加入哪个队列（一个全新的轮次，还是当前活跃的轮次），以及这个队列项是否让模型运行。把这个 2×2 编码成三个手写方法，掩盖了其中的对称性，让“排入一个轮次但不唤醒驱动器”无法表达，也让 `cancel()` 无从在保留排队工作的前提下中止一个轮次。
+
+另外，`context/message` 与 `user/message` 已经趋同：对外接口把二者都投影为逐字的 user 角色内容，唯一真正的区别是注入的上下文携带 `source`/`meta` 且“不是提示词”。一个投影对应两种事件类型，意味着每个消费方都要根据事件类型分支来回答“这是不是一条人类提示词？”，而 goal 系统把这种类型区分当作侧信道使用（第 0 轮的状态变更是 `context/message`，已准入的轮次是 `user/message`）。
+
+## 决策
+
+**一种接受机制，四种意图辅助方法。** 具体循环把 `followup`、`queue`、`steer` 和 `inject` 解析到同一个（`target` × `wakeup`）接受机制中。`followup` 是 `next-turn`/wakeup，`queue` 是 `next-turn`/no-wakeup，`steer` 是 `next-step`/wakeup，`inject` 是 `next-step`/no-wakeup。公开的结构化接口将该机制暴露为 `send(ResolvedAgentInput)`；调用方若已持有完全解析的路由信息，即可使用该方法。使用时必须提供所有字段，可辨识输入类型也不允许注入携带附加上下文。取代旧接口的选择由[按意图命名的投递决策](2026-07-24-intent-named-agent-delivery.md)负责说明。内部的 `wakeup` 表示「让模型运行」：为一条普通消息唤醒处于停泊状态的驱动器，或强制运行中的 steering 继续执行。
+
+**inject 保留其机制。** `inject` 在当前日志位置追加持久、面向模型的上下文（在执行中的工具批处理之后延迟处理），或在空闲时开启一个一次性的 `injection` 轮次。它完全绕过 FIFO，不接受附加上下文，并把来源默认设为 `{ kind: 'plugin', plugin: '' }`，绝不是 `{ kind: 'user' }`。
+
+**context/message 已移除。** 注入的上下文现在是一条 `user/message`，其 `source` 为非 `user` 类别（plugin 或 goal）。`PromptMessageData` 新增了 `context/message` 原本携带的可选 `meta`。对外接口、派生逻辑和 `SurfaceEventType` 都不再包含 `context/message`；需要判断“这是不是一条人类提示词？”的消费方改为读取 `source.kind === 'user'`，而不是事件类型。这让 goal-authority 的人类授权检查与此前一样严格——注入的消息默认使用 plugin 来源，永远无法满足 `source.kind === 'user'`。
+
+**goal 回放靠轮次而非类型来区分。** 一次 goal 状态变更是一条第 0 轮、来源为 goal 的 `user/message`，携带 `goal/change` 元数据；正数轮次则是一条已准入的继续执行提示词。`decodeGoalEvent` 现在接收一条 `user/message`，并仍会在非 goal 来源携带 goal 元数据、或 goal 来源缺少元数据时立即报错。
+
+**投递返回一个 id。** 每种投递方法都为被接受的输入返回一个不透明的 branded `AgentMessageId`。FIFO 方法通过其 inbox 生命周期事件携带这个 id；注入绕过这些事件。
+
+**三个 inbox 事件取代 agent/queued。** `agent/inbox/enqueue`（一个队列项进入某个 FIFO）、`agent/inbox/dequeue`（驱动器认领了一个）和 `agent/inbox/discard`（`cancel()` 丢弃了待处理项）都携带一条 `AgentMessage`——即被接受的消息，包含其返回的 `id`、steering/wakeup 事实、来源和上下文——因此调用方可以把一个排队项与其生命周期关联起来。注入从不触及 FIFO，也不发出这些事件中的任何一个。每一次 FIFO 入队都会发布一个 enqueue 事件，包括由 loop 生成的携带继续原因的 steer（`agent/turn-continuation` 返回 `{ action: 'continue', reason }`），因此账目会与其后的 dequeue 或 discard 保持平衡。`dsh-agent` 的不变量配套断言 FIFO 守恒：一个按 agent 计的未结算计数，dequeue 和 discard 永远无法把它压到负数。
+
+**cancel 新增 keepInbox。** `cancel(cause?, { keepInbox? })`；当其为 true 时，它中止活跃轮次，但保留排队项和 steering 项（不发出 discard 事件，尚未启动的工作也不会被丢弃）。
+
+## 考虑过的替代方案
+
+- **为注入内容设立专门的 `MessageSource` 类别 `context`。** 不予采纳，因为 `plugin` 已经表示“不是人类”，因此第四种类别会增加一条平行的轴，让授权检查不得不去学习它。注入的上下文改为默认使用 plugin 来源。
+- **在 `PromptMessageData` 上设一个类型化的判别字段**（例如 `origin: 'prompt' | 'context'`）来取代事件类型的区分。不予采纳，转而采用 `source`——每个消费方都已经携带它，goal 系统也已经以它为键；第二个判别字段会重复这一事实。
+- **在 inbox 事件之外保留 `agent/queued`。** 作为镜像而被否决：`agent/inbox/enqueue` 是同一个入队时刻的信号，只是多带了已接受的路由事实，而 dequeue/discard 事件补全了单个事件无法描述的 FIFO 生命周期。
+
+## 后果
+
+具体驱动器只有一个投递机制。四种常用辅助方法以调用方意图封装其（`target` × `wakeup`）矩阵，而 `send` 则向高级调用方暴露完全解析后的矩阵。一种持久消息类型同时服务提示词、注入的上下文和 goal 轮次，因此对外接口的投影和每一处「是否人类提示词？」检查都简化为一次 `source` 判断。goal 折叠的通道区分从事件类型改到 `source.round`，此前过滤 `context/message` 的每个消费方都改为按来源过滤 `user/message`。轮次封闭与重建的不变量保持不变：空闲状态下的一次注入仍然封装成一个一次性轮次，只是现在发出 `user/message` 而非 `context/message`。
+
+在内部，`wakeup` 是“模型是否应当运行”的信号，因此 inbox 区分 `hasWakingQueued`（驱动 loop 以及空闲/静默判定）与 `hasQueued`（是否有任何可 dequeue 的项）：一个孤立的 `queue()` 项会停泊在空闲状态，并随下一条会唤醒驱动器的后续消息一同带出，而 `whenIdle`/`cancel` 依据唤醒信号来结算静默（一个孤立的静默项走 `whenIdle` 的快速路径，因此不会让任何等待者悬而未决）。排队消息或 steering 消息上的 `SendOptions.meta` 会被带到持久的 `user/message`/`steering/message` 上，与注入保持一致；它有意不放在实时的 `AgentMessage` 上，后者只携带路由事实。每个已入队的 id 都恰好得到一个终止性生命周期事件：一次会丢弃待处理 steering 项的终止性停止会为它发出 `agent/inbox/discard`，既在轮次内的停止点，也在轮次结束后对迟到 steering 的清空时；dispose（资源释放）会在 loop 退出前丢弃所有仍在等待的项。`agent/inbox/*` 的事件载荷已被冻结，因此监听器无法在分发中途修改共享的关联对象，而由 loop 生成的继续原因会像公开 steering 一样被快照并冻结。注入会在打开空闲状态的一次性轮次之前校验其载荷；`InjectOptions` 不包含附加上下文，而 `ResolvedAgentInput` 中不唤醒的下一步变体要求使用空上下文元组。

**Host side — compose the graph.**
-1. The composing app (`apps/cli`) mounts the roster as in-memory Loader entries via `mountWebPlugins`. The roster is one flat list of the plugin packages, plus the `client-hmr` row under `--dev`. A roster package that fails to import throws loud at mount.
-2. The registry (`createHostWebPluginRegistry`) scans the mounted entries' package.json `dshClient` declarations and composes `window.__DSH_BOOT__`: `{ rev, entries: [{ id, url, rev, inject?, immediately? }] }`. The `inject` edges and the `immediately` mark come from manifests, never hand-copied. It refuses a declared plugin without a built `./client` bundle, and any malformed declaration field — load-time fail loud.
-3. The registry rescans on cordis `internal/plugin`, microtask-debounced; a rescan failure keeps serving the previous graph. Each bundle's content is hashed into its `rev` (cache busting + HMR diff anchor), and the row set into `graph.rev`. Every row is fetch-served: `/plugins/<id>/client.js?rev=…`. The graph types are a wire contract dual-held on both sides, because the webserver keeps zero workspace dependencies.
+1. The composing app (`apps/cli`) ships the roster as ordinary rows in its `cordis.yml` config tree — client plugin packages are entry rows like every host plugin, and `--dev` appends the `client-hmr` row in code (`AppCLIEntry`) before the settle/sweep so the fail-loud triple covers it. A roster row that fails to import is caught by the boot's `assertEntriesLoaded`.
+2. The `dsh-client-modules` node half (the package is dual-face: its browser half is the module table) scans loader entries' package.json `dshClient` declarations and composes `window.__DSH_BOOT__`: `{ rev, entries: [{ id, url, rev, inject?, immediately? }] }`. The `inject` edges and the `immediately` mark come from manifests, never hand-copied. It refuses a declared plugin without a built `./client` bundle, and any malformed declaration field — activation-time fail loud (a FAILED fiber the sweep reports).
+3. Scanning is incremental per package — there is no full-rescan code path. Each cordis `internal/plugin` emission marks the fiber's entry name dirty (entry-less fibers drop O(1)); a microtask flush reconciles each dirty name against live loader entries, with package metadata (including the negative "not a client package" verdict) cached per name forever and bundle re-hashing reachable only through `rebuilt(id)`. The activation pass seeds the same dirty set from current entries and flushes synchronously, so first scan and steady state share one implementation. Each bundle's content hash is its `rev` (cache busting + HMR diff anchor), the row set hashes into `graph.rev`, and every row is fetch-served: `/plugins/<id>/client.js?rev=…`. The graph types are single-sourced in the modules package's `./impl` export — the webserver knows nothing about the graph (it is a plain route-registration plugin; modules registers the bundle route and taps the index render itself).
-Why is the roster a hand-written list and not a scan? Because which plugins compose into a deployment is a composition decision, not a package property — a dshClient package existing in the repo does not mean this deployment mounts it, so discovery-by-scan cannot make that call. The roster lives in `apps/cli/web.ts` rather than cordis.yml only because `dsh web`'s host is a hand-assembled `bootHost` with no Loader config tree yet.

**Phase one — the module face.** The shell builds the module system over the graph, then prefetches every `immediately` row in parallel. Prefetch is fetch + execute, which registers factories only. A single row's prefetch failure is swallowed here: phase two's import retries the fetch and owns the loud failure, so one bad row cannot mask the others. `immediately` is a prefetch mark — not a barrier, not an identity. The package declares it, the registry carries it into the row. The infrastructure plugins (connection, runtime, ui-theme, i18n, plus hmr) declare it; UI plugins simply arrive on demand.

Polling is by design: inotify does not fire on the weka network mount, the same reason the build-side watcher needs `--poll`. On a mtime/size change the registry re-hashes that row (`rebuilt(id)`); when the `rev` actually changed, it broadcasts a `rebuilt` frame on `GET /plugins/events` — a system SSE channel that sends the full graph on connect and `rebuilt` frames on change, presentation-only wire that never enters the session log. Watch set membership follows the table: rescans add watches for new rows and drop them for vanished ones, dispose drops all. The poll interval is a validated config field (default 500ms), not a constant. Rebuilding the bundles is any tsdown watch process's business — `scripts/dev-web.ts` remains as the watch-build entry point, its package list dshClient-discovered by scanning `packages/*/*/package.json` at startup — and builder and host share zero protocol.

It reads bundle paths from `ctx.clientModuleHost.clientPath(id)`, and one HMR-owned interval stat-polls every current graph row. Adding a row is ordered as synchronous stat baseline, then immediate `clientModuleHost.rebuilt(id)`: a write after the module host's graph hash but before that baseline is caught by the immediate re-hash, while a write after the baseline leaves a stat delta for the next poll. This avoids `fs.watchFile`, whose asynchronous first baseline can silently absorb a construction-time rebuild. Watch membership follows `onGraphChanged`; vanished rows drop out, and a bundle missing at poll time keeps its row dirty so reappearance forces a re-hash even with identical metadata. On a mtime/size delta or dirty row, `clientModuleHost.rebuilt(id)` is the single re-hash entry point; when the `rev` actually changed, the node half broadcasts a `rebuilt` frame on `GET /plugins/events` — a system SSE channel that sends the full graph on connect and `rebuilt` frames on change, presentation-only wire that never enters the session log.

+# Agent Note: Parse `dsh` argv through one Commander adapter
+
+Status: implemented
+
+English | [中文](2026-07-24-dsh-commander-argument-adapter.zh.md)
+
+## Problem
+
+The `dsh` CLI entry (`apps/cli`) parsed argv in three hand-rolled idioms that did not compose and gave no `--help`/`--version`. `bin.ts` dispatched by raw inspection — `argv[0] === 'web'`, then `argv.includes('-p') || argv.includes('--prompt')`, else TUI — which is positional-blind: a prompt flag or a config path in the wrong position could misroute the mode, and `argv.includes('-p')` could not tell a real flag from an incidental token. `headless.ts` and `web.ts` each ran their own `node:util` `parseArgs` with inline host/port validation, and `dsh-app-boot` carried `parseResumeArg`, a ~30-line bespoke scanner reimplementing flag/`=`-form/value/repeat handling for `--resume`. Usage was a single hardcoded `usage: dsh -p "task"` line; there was no version flag and no rendered help.
+
+## Decision
+
+Argv is parsed once, in `apps/cli/src/args.ts`, through a Commander adapter (the same parser the SDK bins — `create-sdk`, `dsh-scripts` — already standardize on). `parseDshArgs(argv, version)` returns a discriminated `DshInvocation` union of the three real modes: `{ mode: 'tui', config?, resume? }`, `{ mode: 'headless', prompt }`, or `{ mode: 'web', host?, port?, dev }`. It does **not** model help/version/errors as data: Commander owns those, printing usage or the diagnostic and exiting at the point of failure. `exitOverride()` turns each into a thrown `CommanderError` carrying the intended code (0 for help/version, 1 for a parse or domain error), which one `try/catch` in `parseDshArgs` turns into `process.exit`.
+
+`bin.ts` calls the adapter once and switches on `mode` (closed union, `satisfies never` default), dynamic-importing only the chosen mode's module; only a valid, non-help invocation reaches the switch, so it has no help/version/error cases. Each mode module consumes already-parsed values: `runTui(config, resume)`, `runHeadless(task)`, `runWeb(host, port, dev, workspaceRoot)` — none re-reads argv. It is **one Commander program**: the default surface (no subcommand) carries option-only flags — `--config <path>`, `-p/--prompt <task>`, `--resume <id>` — and `web` is a real `program.command('web')` subcommand. The default surface takes no positional argument, which is what lets `web` be a real subcommand without a positional collision, so `dsh --help` lists `web` natively (no hand-pasted command text). The default action and the `web` action set the resolved mode, then bail via `command.error(...)` (print + exit 1) on the domain checks Commander cannot express: `--prompt` selects headless and rejects an empty task or a `--config`/`--resume` alongside it rather than silently dropping a TUI input; an empty `--resume=` id fails loud (agent-loop treats `''` as no-resume). Commander parses the default-surface options on either side of the `web` token into `program.opts()`; since `web` shares none of them, the `web` action rejects a leaked `--config`/`-p`/`--resume` (`dsh web -p x`, `dsh --config c.yml web`) rather than silently serving and dropping it. `dsh web`'s `--host`/`--port` are unvalidated pass-through overrides: the adapter assigns no default and does no validation, only `Number`-coercing the port string (the schema wants a number). The `dsh-host-webserver` schemastery `Config` (`host` a `127.0.0.1`/`0.0.0.0` literal union, `port` a natural ≤ 65535) is the single source of both the default (the shipped `apps/cli/cordis.yml` `webserver` row stands when a flag is absent) and validity — `AppCLIEntry` patches an explicit flag straight into that row, so a bad host/port fails loud at the schema on boot, not at parse. `--dev` mounts the client HMR driver and bundle watch, and `--workspace-root <path>` is a plain pass-through to `AppCLIEntry` (the parent directory for name-created workspaces). A repeated `--resume`, or a following flag captured as a `--resume`/`--prompt` value, is Commander's standard behavior (last-wins / next-token) and is left alone; a bad id fails loud downstream when the session cannot load. `--version` reads this app's `package.json`.
+
+`dsh` takes no positional argument. `--config <path>` names an alternate cordis tree to boot instead of the shipped default; it exists only so the demo/test call sites (`demo:cordis`, `demo:code-mode`, the keyless PTY smokes) can point the shipped bin at an example tree. A bare `dsh` boots the shipped tree plus the `~/.dsh/config.yaml` personal overlay; a real user never passes `--config`.
+
+CLI parsing lives entirely in `apps/cli`. `dsh-app-boot` holds the boot/env/config/personal-overlay helpers and no argv scanner.
+
+## Session resume through the boot context
+
+`dsh --resume <id>` is the one way to resume a persisted session, with no environment variable. `runTui` provides the parsed id on the boot context through `boot`'s `prepare(ctx)` hook — `ctx.provide(RESUME_SESSION_ID_KEY, id)` (a `dsh-app-boot` export, value `'resumeSessionId'`) — and the shipped tui-agent/cordis configs read it as a bare identifier: `resumeSessionId: !!js "typeof resumeSessionId === 'string' ? resumeSessionId : undefined"`. The expression is quoted because YAML otherwise parses the `?`/`:` as a mapping; the `typeof` guard tolerates a launcher that never provides the slot. The `/resume` in-place handoff (`process.execve`) rebuilds its re-exec argv from the parsed values as `dsh --resume=<id> [--config <path>]`.
+
+## One terminal front door: `dsh`
+
+`dsh` is the only terminal entry point; the `dsh-tui-demo` package ships the TUI app bundle plugin the shipped config mounts, and no bin of its own. `demo:cordis`, `demo:code-mode`, and both the tui-agent and cordis-agent keyless PTY smokes launch through `apps/cli/src/bin.ts` with `--config <path>`. `dsh`'s TTY guard (refuse piped stdio before booting, pointing at `dsh -p` for automation) is pinned by `apps/cli/tests/built-bin.e2e.ts`, which runs the built `lib/bin.js` under plain Node with piped stdio (`apps/cli/tests` is in the e2e vitest include). `cli-demo`, `acp-demo`, and `jsonrpc-demo` keep their own bins because each is a distinct surface (headless, ACP, JSON-RPC) `dsh` does not provide.
+
+## Package topology
+
+The argument surface stays inside `apps/cli`, the assembly tier, not a `packages/*` library: it is this one app's routing, not a reusable seam. `dsh-app-boot` shrinks to boot glue with no CLI-parsing responsibility. `commander@^15` is added to `apps/cli/package.json`, matching the SDK bins' pin.
+
+## Alternatives considered
+
+**Keep `node:util` `parseArgs` and only unify the dispatch** — rejected: `parseArgs` has no subcommand model, no rendered help, and no version flag, so `web` routing and `--help`/`--version` would stay hand-rolled. The repo already chose Commander for its other CLIs; a second parser idiom for `dsh` alone is the fragmentation this change removes.
+
+**Keep `parseResumeArg` as a shared helper and feed it Commander's residual args** — rejected: the whole point is to retire the bespoke scanner. Commander parses `--resume` (space and `=` forms, missing-value, position-independence) natively; keeping a parallel hand-written path for the one flag would preserve the duplication the change exists to end.
+
+**A bare `dsh <config>` positional for the alternate tree** — rejected: a root positional and a real `web` subcommand cannot coexist in one Commander program (the subcommand claims the first positional). A positional would force `web` into a reserved-first-token dispatch to a separate parser and a hand-maintained `web` line in `--help`. Only the demo/test sites ever need to name an alternate tree, so a `--config` flag serves them while leaving the default surface positional-free — `web` is then a normal subcommand in one program with native `--help`.
+
+**Make the argument surface a `packages/*` seam** — rejected: nothing outside `dsh` consumes it, and capability seams are not split preemptively. The Commander adapter is `apps/cli`'s own concern.
+
+**Keep `RESUME_SESSION_ID` as the resume bridge** — rejected: with `--resume` parsed into a value the bin already holds, threading it through an environment variable the config re-reads is indirection with no benefit, and it left the demo bin a second, env-only resume path. Providing the id on the boot context is the same channel `boot`'s `prepare` hook already uses for `tuiResumeHost`.
+
+**Keep the `dsh-tui-demo` bin** — rejected: it duplicated `dsh --config <path>` exactly, and keeping it forced the demo-only `RESUME_SESSION_ID` fallback to stay alive. Its plugin is what the configs actually mount; only the front-door bin was redundant, and `dsh` is the one terminal entry point.
+
+## Testing
+
+`apps/cli/tests/args.spec.ts` (new; `apps/*/tests` added to the vitest include and `apps/cli/tests` to `tsconfig.host.json`) covers the adapter at the level that matters: mode routing by shape (including `web --dev` and the host/port pass-through), the exit-code behavior for the adapter's fail-loud checks (empty resume/prompt, `--prompt` mixed with a config/`--resume`, unknown option, stray positional), and `--help`/`--version`, captured through a `process.exit` spy. Host/port validity is the webserver schema's job, exercised on boot by the web smoke, not the adapter spec. Both PTY smoke groups in `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` now drive the real `apps/cli/src/bin.ts`: the `tui-agent` group boots an example tree through `--config`, and the `dsh CLI` group covers default boot, personal overlay, invalid config, the `--resume` config intake, the `process.execve` in-place resume handoff, and the source-path prompt. `examples/cordis-agent/tests/keyless-smoke.e2e.ts` likewise launches through `dsh`. `packages/ui/app-boot/tests/app-boot.spec.ts` drops its `parseResumeArg`/`replaceResumeArg` blocks; the TUI unit and snapshot fixtures use the `dsh --resume {session}` resume command.
+
+## Consequences
+
+`dsh` has rendered `--help`/`--version` and consistent fail-loud parse errors, and mode routing does not depend on flag position. Argv parsing lives in one place with one parser idiom shared with the SDK bins, at the cost of a `commander` dependency on `apps/cli` and Commander's parse semantics (its error strings, its `exitOverride` contract) sitting on the CLI's front door. `dsh-app-boot` owns no CLI-parsing surface; a consumer needing `--resume`-style parsing composes Commander. Session resume rides the boot context rather than an environment variable, and `dsh` is the single terminal front door — the `dsh-tui-demo` package is a plugin bundle a config mounts.

+# Agent Note: 通过单个 Commander 适配器解析 `dsh` 的 argv
+
+Status: implemented
+
+[English](2026-07-24-dsh-commander-argument-adapter.md) | 中文
+
+## 问题
+
+`dsh` 的 CLI（命令行界面）入口（`apps/cli`）以三种手写方式解析 argv，这些方式无法组合，也不提供 `--help`/`--version`。`bin.ts` 通过原始检查进行分发：先判断 `argv[0] === 'web'`，再判断 `argv.includes('-p') || argv.includes('--prompt')`，否则走 TUI。这种方式对位置不敏感：位置错误的 prompt 标志或配置路径可能把模式路由错，而 `argv.includes('-p')` 无法区分真正的标志和偶然出现的 token。`headless.ts` 和 `web.ts` 各自运行自己的 `node:util` `parseArgs`，并内联校验 host/port，而 `dsh-app-boot` 携带 `parseResumeArg`——一个约 30 行的定制扫描器，为 `--resume` 重新实现了标志、`=` 形式、取值和重复的处理。用法说明只有一行硬编码的 `usage: dsh -p "task"`；既没有版本标志，也没有渲染出的帮助信息。
+
+## 决策
+
+argv 只在 `apps/cli/src/args.ts` 中解析一次，并使用 Commander 适配器（SDK bin `create-sdk`、`dsh-scripts` 已经统一采用的同一解析器）。`parseDshArgs(argv, version)` 返回仅包含三种实际模式的判别式 `DshInvocation` 联合类型：`{ mode: 'tui', config?, resume? }`、`{ mode: 'headless', prompt }` 或 `{ mode: 'web', host?, port?, dev }`。它**不会**将帮助、版本信息或错误建模为数据：这些情况由 Commander 处理，在触发处打印用法或诊断信息并退出。`exitOverride()` 会将每种情况转为抛出的 `CommanderError`，并携带预期退出码（帮助或版本为 0，解析错误或领域错误为 1）；唯一一处 `try/catch` 位于 `parseDshArgs` 中，捕获错误后调用 `process.exit`。
+
+`bin.ts` 只调用适配器一次，并对 `mode` 做分支切换（封闭联合类型，默认分支为 `satisfies never`），仅动态导入所选模式对应的模块；只有合法的非帮助请求才会进入这段分支逻辑，因此其中没有帮助、版本或错误分支。每个模式模块只消费已解析好的值：`runTui(config, resume)`、`runHeadless(task)`、`runWeb(host, port, dev, workspaceRoot)`，都不会再次读取 argv。整个 CLI 由**单个 Commander 程序**实现：默认接口（不使用子命令时）只包含选项标志——`--config <path>`、`-p/--prompt <task>`、`--resume <id>`——而 `web` 是通过 `program.command('web')` 定义的真正子命令。默认接口不接受位置参数，因此 `web` 可以成为真正的子命令且不会发生位置参数冲突，`dsh --help` 也会原生列出 `web`，无需手工拼接命令文本。默认命令和 `web` 子命令的处理函数会设置解析得到的模式，随后对 Commander 无法表达的领域校验调用 `command.error(...)` 立即终止（打印信息并以退出码 1 退出）：`--prompt` 选择 headless 模式；如果任务为空，或调用中还包含 `--config` 或 `--resume`，它会拒绝调用，而不会静默丢弃 TUI 输入；空的 `--resume=` id 会显式失败（agent-loop 把 `''` 视为不恢复）。Commander 会将 `web` token 前后的默认接口选项都解析进 `program.opts()`；由于 `web` 不与默认接口共用任何选项，`web` 子命令的处理函数会拒绝误入的 `--config`/`-p`/`--resume`（`dsh web -p x`、`dsh --config c.yml web`），而不是静默启动服务并丢弃这些选项。`dsh web` 的 `--host`/`--port` 是未经校验、直接透传的覆盖值：适配器既不设置默认值，也不执行校验，只使用 `Number` 将端口字符串转换为数字（schema 要求该值为数字）。`dsh-host-webserver` 的 schemastery `Config`（`host` 是 `127.0.0.1`/`0.0.0.0` 字面量联合类型，`port` 是不大于 65535 的自然数）是默认值与有效性的唯一真源：未提供标志时，随产品提供的 `apps/cli/cordis.yml` 中 `webserver` 配置项保持原值；`AppCLIEntry` 将显式标志的值直接写入该配置项，因此无效的 host/port 会在启动时触发 schema 校验并显式失败，而不是在参数解析阶段失败。`--dev` 会挂载客户端 HMR（热模块替换）驱动，并启用构建产物监视，`--workspace-root <path>` 则是直接透传给 `AppCLIEntry` 的选项（按名称创建 workspace 时使用的父目录）。重复提供 `--resume`，或后续标志被捕获为 `--resume` 或 `--prompt` 的值，都是 Commander 的标准行为（最后一次取值生效／将下一 token 作为值），本适配器不作干预；无效 id 会在下游无法加载会话时显式失败。`--version` 读取本应用的 `package.json`。
+
+`dsh` 不接受位置参数。`--config <path>` 指定一份替代 Cordis 配置树，系统启动该配置树而不是随产品提供的默认配置树；该标志仅用于让演示和测试调用点（`demo:cordis`、`demo:code-mode`、无密钥 PTY 冒烟测试）通过随产品提供的 bin 启动一份示例树。直接运行 `dsh` 会启动随产品提供的配置树，并叠加 `~/.dsh/config.yaml` 个人覆盖；实际用户从不传入 `--config`。
+
+CLI 解析完全位于 `apps/cli` 中。`dsh-app-boot` 提供启动、环境变量、配置和个人覆盖辅助函数，不包含 argv 扫描器。
+
+## 通过启动上下文恢复会话
+
+`dsh --resume <id>` 是恢复持久化会话的唯一方式，无需环境变量。`runTui` 通过 `boot` 的 `prepare(ctx)` 钩子，在启动上下文中提供已解析的 id：`ctx.provide(RESUME_SESSION_ID_KEY, id)`（`dsh-app-boot` 的一项导出，值为 `'resumeSessionId'`）；随产品提供的 tui-agent/cordis 配置将该值作为裸标识符读取：`resumeSessionId: !!js "typeof resumeSessionId === 'string' ? resumeSessionId : undefined"`。这个表达式需要加引号，否则 YAML 会把 `?` 和 `:` 解析为映射；`typeof` 守卫使从未提供该槽位的启动器也能正常运行。`/resume` 原地交接（`process.execve`）根据已解析的值将重新执行时的 argv 构造成 `dsh --resume=<id> [--config <path>]`。
+
+## 唯一的终端入口：`dsh`
+
+`dsh` 是唯一的终端入口；`dsh-tui-demo` 包（package）提供 TUI 应用组合插件，随产品提供的配置会挂载该插件，而该包不提供自己的 bin。`demo:cordis`、`demo:code-mode` 以及 tui-agent 和 cordis-agent 的无密钥 PTY 冒烟测试都通过 `apps/cli/src/bin.ts` 启动，并传入 `--config <path>`。`dsh` 的 TTY 守卫会在启动前拒绝标准输入输出接入管道的调用，并提示自动化场景使用 `dsh -p`；`apps/cli/tests/built-bin.e2e.ts` 锁定了这一行为：该测试将标准输入输出接入管道，并通过普通 Node 运行构建后的 `lib/bin.js`（e2e Vitest 的 include 包含 `apps/cli/tests`）。`cli-demo`、`acp-demo` 和 `jsonrpc-demo` 保留各自的 bin，因为它们分别提供 `dsh` 所没有的独立接口（headless、ACP（Agent Client Protocol）、JSON-RPC）。
+
+## 包拓扑
+
+参数解析留在 `apps/cli`（组装层）内，而不是 `packages/*` 库中：它是这一个应用自身的路由，而非可复用的 seam。`dsh-app-boot` 收缩为纯粹的 boot 胶水代码，不再承担 CLI 解析职责。`commander@^15` 被加入 `apps/cli/package.json`，与 SDK bin 锁定的版本一致。
+
+## 考虑过的替代方案
+
+**保留 `node:util` `parseArgs`，只统一分发。** 已否决：`parseArgs` 没有子命令模型、没有渲染出的帮助、也没有版本标志，因此 `web` 路由和 `--help`/`--version` 仍将保持手写。本仓库其他 CLI 已经选择了 Commander；单独为 `dsh` 引入第二套解析器方式，正是这次变更要消除的碎片化。
+
+**保留 `parseResumeArg` 作为共享辅助函数，并向它喂入 Commander 的残余参数。** 已否决：整件事的核心就是要退役这个定制扫描器。Commander 原生解析 `--resume`（空格和 `=` 形式、缺值、位置无关性）；为这一个标志保留一条平行的手写路径，只会保留这次变更要终结的重复。
+
+**使用裸 `dsh <config>` 位置参数指定替代配置树。** 已否决：根级位置参数与真正的 `web` 子命令无法在同一个 Commander 程序中共存（子命令会占用第一个位置参数）。位置参数会迫使系统把位于首位的 `web` 作为保留 token 分发给另一个解析器，并手工维护一行 `web` 文本，供 `--help` 显示。只有演示和测试调用点需要指定替代配置树，因此 `--config` 标志既能满足这些调用点，又能让默认接口不包含位置参数；这样，`web` 就能在单个程序中成为普通子命令，并由原生 `--help` 展示。
+
+**把参数解析做成 `packages/*` 的 seam。** 已否决：`dsh` 之外没有任何消费方使用它，而能力 seam 不应被提前拆分。这个 Commander 适配器是 `apps/cli` 自身的事务。
+
+**保留 `RESUME_SESSION_ID` 作为恢复通道**：不予采纳。`--resume` 已被解析成 bin 当前持有的值；若再通过环境变量传递并由配置重新读取，只会引入无益的间接层，还会使演示 bin 保留第二条仅依赖环境变量的恢复路径。在启动上下文中提供 id，与 `boot` 的 `prepare` 钩子为 `tuiResumeHost` 提供值所采用的是同一通道。
+
+**保留 `dsh-tui-demo` bin**：不予采纳。它与 `dsh --config <path>` 的功能完全重复；保留它还会迫使演示专用的 `RESUME_SESSION_ID` 回退路径继续存在。配置实际挂载的是该包的插件；冗余的只有作为终端入口的 bin，而 `dsh` 是唯一的终端入口。
+
+## 测试
+
+`apps/cli/tests/args.spec.ts`（新增；`apps/*/tests` 加入 vitest include，`apps/cli/tests` 加入 `tsconfig.host.json`）覆盖适配器的关键行为：根据参数形态进行模式路由（包括 `web --dev` 和 host/port 透传），并通过 `process.exit` spy 捕获适配器的显式报错检查（恢复 id 或提示词为空、`--prompt` 与配置或 `--resume` 混用、未知选项、多余的位置参数）以及 `--help`/`--version` 的退出码。host/port 的有效性由 webserver schema 负责，并由 web 冒烟测试在启动时验证，不属于适配器测试的覆盖范围。`examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` 中的两组 PTY 冒烟测试现在都驱动真实的 `apps/cli/src/bin.ts`：`tui-agent` 组通过 `--config` 启动示例树，`dsh CLI` 组覆盖默认启动、个人覆盖、无效配置、配置对 `--resume` 的接收、通过 `process.execve` 原地恢复交接，以及包含源码路径的系统提示词。`examples/cordis-agent/tests/keyless-smoke.e2e.ts` 同样通过 `dsh` 启动。`packages/ui/app-boot/tests/app-boot.spec.ts` 移除其 `parseResumeArg` 和 `replaceResumeArg` 测试块；TUI 单元测试和快照 fixture（测试前置数据）使用 `dsh --resume {session}` 恢复命令。
+
+## 影响
+
+`dsh` 会渲染 `--help`/`--version`，并以一致方式显式报告解析错误；模式路由不依赖标志位置。argv 解析集中在一处，并与 SDK bin 共用一套解析器方式，代价是 `apps/cli` 依赖 `commander`，且 Commander 的解析语义（错误字符串和 `exitOverride` 契约）成为 CLI 入口的一部分。`dsh-app-boot` 不提供任何 CLI 解析接口；需要 `--resume` 式解析的消费方通过组合 Commander 来实现。会话恢复通过启动上下文完成，而不使用环境变量；`dsh` 是唯一的终端入口；`dsh-tui-demo` 包是由配置挂载的插件组合包。

+# Agent Note: Name public agent delivery by intent
+
+Status: implemented
+
+English | [中文](2026-07-24-intent-named-agent-delivery.zh.md)
+
+## Problem
+
+A configurable `send(content, { target?, wakeup?, ... })` makes every caller learn the loop's routing matrix, its defaults, and the interaction between active-turn targeting and model activation. Optional routing fields also let advanced-looking calls silently become ordinary sends. Most callers have one semantic intent, while some adapters already possess exact routing facts and should not have to reverse-map them into a helper name.
+
+Sharing helper implementations through an abstract `Agent` class also makes the public seam nominal in practice. Object-literal adapters and tests must inherit prototype methods even though the package promises a swappable structural handle. The shared base exists only to forward fixed arguments, while the concrete loop remains the sole production adapter.
+
+## Decision
+
+`Agent` is a structural interface with four intent-named delivery helpers:
+
+- `followup()` queues an ordinary turn and wakes the driver.
+- `queue()` queues an ordinary turn without waking an idle driver.
+- `steer()` targets the running turn and requests another step; while idle it becomes a waking ordinary turn.
+- `inject()` appends model-facing context without running the model.
+
+`followup`, `queue`, and `steer` accept `SendOptions`; `inject` accepts `InjectOptions`, which omits attached contexts because injection has no inbox item to own them. `followup` names the waking next-turn operation used for both initial prompts and later independent prompts.
+
+`Agent` also exposes `send(ResolvedAgentInput)` for callers that already hold the complete route. Every field is mandatory: content, source, contexts, metadata (possibly `undefined`), target, and wakeup. The discriminated union requires the empty context tuple for non-waking next-step injection. `ReactLoopAgent` implements this method once, and all four helpers resolve their defaults before delegating to it. The method accepts the delivery facts as one resolved input; acceptance can still lead to later dequeue, discard, or durable injection rather than eventual delivery.
+
+The target/wakeup matrix is an explicit advanced part of the structural `Agent` interface, not the ordinary helper options and not a base-class implementation seam. With one concrete adapter, a protected subclass seam would be hypothetical; callers and tests use the same public interface.
+
+## Alternatives considered
+
+**Keep the resolved primitive private.** This minimizes the public method count, but forces adapters that already hold exact target/wakeup facts to reverse-map them into helper calls and removes the reusable type for that resolved state.
+
+**Use configurable `send(content, options)` as the primitive.** Optional routing fields would let advanced-looking calls silently become ordinary sends. One mandatory discriminated input keeps the resolved route explicit and rejects attached contexts on injection.
+
+**Name the primitive `acceptInput`, `sendInternal`, or `addMessageAdvanced`.** `acceptInput` describes the synchronous acceptance boundary but not the caller's delivery action. A public method must not describe itself as internal, and `addMessageAdvanced` is inaccurate because the input may later be discarded.
+
+**Use `send(content, options)` as the waking-turn helper.** This reserves the shortest delivery name for one preset and forces callers with complete target/wakeup facts through a less direct primitive name. `followup` distinguishes the next-turn/wakeup intent while leaving `send` for the resolved operation.
+
+**Bind source first through a public sender object.** A source-bound adapter can make attribution explicit for repeated producers, but it adds another public object and does not simplify one-off human input. The existing source default remains, with the standing requirement that non-human producers label their content.
+
+## Verification
+
+Focused agent-loop coverage exercises direct fully resolved acceptance, waking sends, quiet queues, active and idle steering, injection, source/context snapshots, cancellation, and inbox lifecycle correlation through the public methods. Type-level coverage uses structural `Agent` fakes, requires every `ResolvedAgentInput` field, requires empty contexts on its injection variant, and keeps routing fields out of `SendOptions`. The keyless Cordis inspection snapshot pins the structural interface without an abstract-class implementation.
+
+## Consequences
+
+Ordinary callers choose one verb instead of encoding two routing axes; advanced callers may submit the exact discriminated route. The concrete loop retains one acceptance path and one ownership boundary, while the structural interface preserves simple adapters and fakes. Adding a common delivery intent still requires an explicit public helper and mapping rather than another optional matrix combination.
+
+The advanced method adds interface surface and requires structural fakes to implement it. In return, resolved routing has one typed representation, while helper defaults and mappings stay beside the only implementation that owns them.

+# Agent Note: 按意图命名公开的 agent 投递
+
+Status: implemented
+
+[English](2026-07-24-intent-named-agent-delivery.md) | 中文
+
+## 问题
+
+可配置的 `send(content, { target?, wakeup?, ... })` 会迫使每个调用方理解循环的路由矩阵、默认值，以及活跃轮次目标与模型激活之间的相互作用。可选路由字段还会让看似高级的调用悄然变成普通投递。大多数调用方只有一种语义意图，而有些适配器已经持有确切的路由信息，不应再被迫将这些信息反向映射为某个辅助方法名称。
+
+通过抽象 `Agent` 类共享辅助方法的实现，实际上也会让公开 seam 具有名义类型约束。对象字面量适配器和测试必须继承原型方法，尽管该包承诺提供一个可替换的结构化句柄。共享基类只负责转发固定参数，而具体循环仍是唯一的生产适配器。
+
+## 决策
+
+`Agent` 是一个结构化接口，提供四种按意图命名的投递辅助方法：
+
+- `followup()` 将一个普通轮次入队并唤醒驱动器。
+- `queue()` 将一个普通轮次入队，但不唤醒空闲驱动器。
+- `steer()` 以运行中的轮次为目标并请求另一个步骤；空闲时，它会变成一个唤醒式普通轮次。
+- `inject()` 追加面向模型的上下文，但不运行模型。
+
+`followup`、`queue` 和 `steer` 接收 `SendOptions`；`inject` 接收 `InjectOptions`，后者不包含附加上下文，因为注入没有 inbox 项来拥有它们。`followup` 为唤醒式下一轮操作命名，这项操作既用于初始提示词，也用于后续的独立提示词。
+
+`Agent` 还公开 `send(ResolvedAgentInput)`，供已经持有完整路由的调用方使用。每个字段都必须提供：内容、来源、上下文、元数据（可以是 `undefined`）、目标和唤醒标志。对于目标为下一步且不触发唤醒的注入，可辨识联合类型要求上下文为空元组。`ReactLoopAgent` 统一实现这个方法；四个辅助方法都会先解析各自的默认值，再委托给它。调用方以一个解析后的输入向该方法提交各项投递事实；接受之后，工作仍可能在稍后出队、被丢弃或持久注入，而不是最终必然送达。
+
+结构化 `Agent` 接口显式包含面向高级用法的 target/wakeup 矩阵；该矩阵不属于普通辅助方法的选项，也不是基类实现 seam。只有一个具体适配器时，protected 子类 seam 只是假想的；调用方和测试使用同一个公开接口。
+
+## 考虑过的替代方案
+
+**让解析后的原语保持私有。** 这会把公开方法数量降到最低，但会迫使已经持有精确 target/wakeup 路由信息的适配器将其反向映射为辅助方法调用，也会移除表示该解析后状态的可复用类型。
+
+**使用可配置的 `send(content, options)` 作为原语。** 可选路由字段会让看似高级的调用悄然变成普通投递。一个各字段均为必填项的可辨识输入既能让解析后的路由保持显式，也会拒绝为注入附加上下文。
+
+**把原语命名为 `acceptInput`、`sendInternal` 或 `addMessageAdvanced`。** `acceptInput` 描述了同步接受边界，却没有描述调用方的投递操作。公开方法不应在名称中把自己称为内部方法，`addMessageAdvanced` 也不准确，因为输入可能在之后被丢弃。
+
+**使用 `send(content, options)` 作为唤醒轮次的辅助方法。** 这会让最简短的投递名称只表示一种预设操作，并迫使持有完整 target/wakeup 信息的调用方改用一个不够直接的原语名称。`followup` 明确区分下一轮/唤醒意图，并把 `send` 留给解析后的操作。
+
+**先通过公开的发送方对象绑定来源。** 对于重复产生消息的来源，来源绑定适配器可以明确标注归属，但它会增加一个公开对象，也不会简化一次性的人类输入。现有的来源默认值予以保留，同时继续要求非人类生产方标注其内容。
+
+## 验证
+
+聚焦的 agent-loop 覆盖率测试通过公开方法覆盖直接接受完全解析的输入、唤醒式投递、静默排队、活跃与空闲状态下的 steering（中途引导）、注入、来源与上下文快照、取消，以及 inbox 生命周期关联。类型级覆盖使用结构化 `Agent` 测试替身，要求提供 `ResolvedAgentInput` 的每个字段，要求其注入变体的上下文为空，并确保 `SendOptions` 不包含路由字段。无密钥的 Cordis 检查快照固定了不采用抽象类实现的结构化接口。
+
+## 后果
+
+普通调用方选择一个动词即可，无需编码两条路由轴；高级调用方则可提交经过判别的精确路由。具体循环保留一条接受路径和一个归属边界，而结构化接口保留了对简单适配器和测试替身的支持。新增一种常见投递意图时，仍需要显式提供公开辅助方法及其映射，而不是再增加一种可选的矩阵组合。
+
+这个高级方法会扩大接口范围，并要求结构化测试替身实现它。作为回报，解析后的路由只有一种类型化表示，而辅助方法的默认值和映射仍留在拥有它们的唯一实现旁边。
+
+## 相关

+# Agent Note: Project-grouped session directories
+
+Status: implemented
+
+English | [中文](2026-07-24-project-session-directories.zh.md)
+
+## Problem
+
+A persistence root may be local to one project, shared by several projects, temporary, or centralized. The hashed cwd buckets kept all deployments functional but made a shared root difficult to navigate because a developer could not recognize a project from its directory name.
+
+Each JSONL session also occupied one file directly inside the project bucket. That shape had no ownership directory for additional session artifacts such as metadata, attachments, spill files, or coordination state.
+
+## Decision
+
+The JSONL backend stores sessions under a readable project key and gives every session its own directory:
+
+```text
+<configured-root>/
+ --<normalized-cwd>--/
+ <encoded-session-id>/
+ session.jsonl.zstd
+```
+
+Raw mode uses `session.jsonl`, and sessions without a cwd use `_no-cwd`. Filesystem and drive separators become `-`, unsafe code units use `~XXXX`, and the readable name is bounded to keep the component within filesystem limits.
+
+The project key intentionally has no hash suffix. This follows the common human-readable convention used by coding agents and keeps the normalized project path as the complete directory name. The normalization is lossy: paths such as `/a/b-c` and `/a-b/c`, or long paths with the same retained prefix, share one project directory. Their distinct session ids still select separate session directories; reuse of the same session id remains a storage collision and is rejected.
+
+Case-insensitive filesystems can also make differently cased project keys refer to one physical directory. Identity validation accepts such an alternate spelling only when filesystem canonicalization resolves the discovered and expected paths to the same transcript. A different canonical path remains corruption, so case aliases do not weaken the same-id collision check on case-sensitive stores.
+
+The configured root remains a deployment choice. The layout neither selects a global root nor requires projects to share one. When a deployment does centralize storage, project paths remain recognizable; a project-local root uses the same deterministic structure.
+
+The encoded session id names an ownership directory rather than the transcript itself. `SessionPersistence.locate()` continues to return the fixed transcript path, preserving hook `transcript_path` and `DSH_SESSION_JSONL` semantics. Discovery ignores other entries inside the session directory so the backend can add session-owned artifacts without another layout change.
+
+Lazy materialization remains tied to the transcript: `create()` performs no filesystem I/O, and the first append creates the project/session directories before collision-safe transcript publication. Empty directories are not listed as sessions. The backend rejects flat `<project>/<id>.jsonl*` artifacts with an explicit layout error; the pre-release format provides no automatic data migration.
+
+## Alternatives considered
+
+**Keep opaque cwd hashes.** This preserved short names but defeated the requested navigation by project path when several projects share a persistence root.
+
+**Put session files directly in each project directory.** This matched Claude Code and pi's basic file organization but left no session-level ownership boundary for future artifacts.
+
+**Add a collision-resistant hash suffix.** This distinguishes paths whose normalized forms collide, but makes the directory name more than the normalized project path. The chosen convention accepts lossy project grouping in exchange for the simpler, recognizable name.
+
+**Mandate a centralized root.** Rejected because storage placement belongs to deployment configuration. Project grouping is useful when roots are shared and harmless when they are not.
+
+**Load both flat and directory layouts.** Rejected under the pre-release no-compatibility stance. One accepted layout keeps identity checks and discovery deterministic.
+
+## Consequences
+
+Shared stores can be navigated by recognizable project names, while local and custom roots keep their existing configuration freedom. Every session has a directory available for future backend-owned artifacts, and existing transcript consumers still receive a file path.
+
+Project directory names are longer than the former 12-hex cwd hashes. Very long paths show only a bounded prefix. Moving a project usually selects a different directory, but distinct cwd strings that normalize to the same name share one project directory by design.

+# Agent Note: 按项目分组的会话目录
+
+Status: implemented
+
+[English](2026-07-24-project-session-directories.md) | 中文
+
+## 问题
+
+持久化根目录可以只供一个项目使用，也可以由多个项目共享，还可以是临时目录或集中式目录。对 cwd 进行哈希得到的分桶目录能适用于所有这些部署方式，但开发者无法从目录名辨认项目，因此共享根目录难以浏览。
+
+每个 JSONL 会话也直接以单个文件的形式放在项目分桶目录中。这种布局没有为元数据、附件、溢写文件或协调状态等其他会话产物提供归属目录。
+
+## 决策
+
+JSONL 后端按可读的项目键存储会话，并为每个会话提供独立目录：
+
+```text
+<configured-root>/
+ --<normalized-cwd>--/
+ <encoded-session-id>/
+ session.jsonl.zstd
+```
+
+原始模式使用 `session.jsonl`，没有 cwd 的会话使用 `_no-cwd`。文件系统路径分隔符和驱动器分隔符会转换为 `-`，不安全的代码单元使用 `~XXXX`，可读名称则限制长度，以确保目录项不超过文件系统限制。
+
+项目键有意不带哈希后缀。这遵循 coding agent（编码智能体）常用的易读约定，使规范化后的项目路径本身就是完整的目录名。规范化过程有损：`/a/b-c` 与 `/a-b/c` 等路径，或者保留前缀相同的长路径，会共用同一个项目目录。不同的会话 id 仍会选择不同的会话目录；复用相同的会话 id 仍构成存储冲突，系统会予以拒绝。
+
+在不区分大小写的文件系统上，大小写不同的项目键也可能指向同一个物理目录。只有当文件系统路径规范化将发现路径和预期路径解析为同一个 transcript（文本记录）时，身份验证才接受这种拼写变体。规范化后的路径如果不同，仍视为存储损坏，因此大小写别名不会让区分大小写的存储放宽同一 id 的冲突检查。
+
+根目录由部署配置决定。这种布局既不选择全局根目录，也不要求项目共享根目录。部署选择集中存储时，目录名仍能让项目路径易于辨认；使用项目本地根目录时，也采用同样的确定性结构。
+
+编码后的会话 id 用于命名归属目录，而不是 transcript 文件本身。`SessionPersistence.locate()` 仍返回固定的 transcript 路径，从而保持钩子 `transcript_path` 和 `DSH_SESSION_JSONL` 的语义不变。发现过程会忽略会话目录中的其他条目，因此后端以后添加会话自有产物时无需再次改变布局。
+
+延迟物化仍以 transcript 为界：`create()` 不执行文件系统 I/O，首次追加会先创建项目目录和会话目录，再以无冲突方式发布 transcript。空目录不会被列为会话。后端会显式报告布局错误并拒绝扁平的 `<project>/<id>.jsonl*` 产物；预发布格式不提供自动数据迁移。
+
+## 考虑过的替代方案
+
+**保留不透明的 cwd 哈希。** 这可以保持目录名简短，但当多个项目共享一个持久化根目录时，无法满足按项目路径浏览的需求。
+
+**把会话文件直接放入各项目目录。** 这与 Claude Code 和 pi 的基本文件组织一致，但没有为未来产物提供会话级归属边界。
+
+**添加防冲突的哈希后缀。** 这种方式能区分规范化形式相同的路径，但会使目录名不再只是规范化后的项目路径。所选约定接受有损的项目分组，以换取更简单、易于辨认的名称。
+
+**强制使用集中式根目录。** 不予采纳，因为存储位置属于部署配置。项目分组在根目录共享时有用，在不共享时也没有负面影响。
+
+**同时加载扁平布局和目录布局。** 按照预发布阶段不提供兼容性的原则，不予采纳。只接受一种布局，可以让身份检查和发现过程保持确定性。
+
+## 后果
+
+共享存储可以通过易于辨认的项目名进行浏览，本地根目录和自定义根目录则继续保有现有的配置自由。每个会话都有一个可供后端未来存放自有产物的目录，而现有 transcript 消费方仍会收到文件路径。
+
+项目目录名比原先由 12 个十六进制字符组成的 cwd 哈希更长。路径很长时，目录名只显示长度受限的前缀。移动项目通常会选择不同的目录，但按设计，不同的 cwd 字符串如果规范化成相同名称，就会共用同一个项目目录。

+# Agent Note: dsh web config-tree boot and the web transport layering
+
+Status: implemented
+
+English | [中文](2026-07-24-web-config-tree-boot-and-transport-layering.zh.md)
+
+> Scope: how `dsh web` composes (cordis.yml + pre-cordis boot classes + config sources) and how the web transport splits across packages (gateway / carrier / binding / graph / dev-reload). The [client plugin loading note](2026-07-23-client-plugin-loading-model.md) owns the browser-side loading chain this composition feeds.
+
+## Problem
+
+`dsh web` was the only hand-assembled surface left: `bootHost` mounted 32 plugins with configs pinned in code (violating no-hardcoded-tunables), the client roster was a `web.ts` constant, and TUI/headless had long been yml compositions. The transport layer misplaced responsibilities to match: the webserver self-described as a dumb carrier yet knew the `__DSH_BOOT__` graph, owned the SSE channel, and hard-coded the `/api/*` prefix; the dev bundle watch lived inside the prod registry behind a `watch?` flag with no lifecycle owner; the graph registry rescanned everything on every `internal/plugin` emission; per-request errors and fatal server errors shared one sink that always exited the process. One user-visible defect rode along: the web path never loaded `$DSH_HOME/.env`, so `DSH_HOME=… dsh web` could not find an API key living there.
+
+## Decision
+
+**Composition is one flat config tree.** `apps/cli/cordis.yml` holds every row — the host runtime (32 rows), the `api-gateway` row, the `webserver` row, and the `dshClient` rows (the browser roster; the modules row is simultaneously a host row). No spine bundle: every plugin is one row and every config field is yml-editable. `--dev` appends the `dsh-client-hmr` row in code before the settle sweep — prod and dev differ by exactly that row. Row order carries no load semantics; activation is service-availability driven, and the boot compensates with a fail-loud triple: `assertEntriesLoaded` (import failures), `installFailLoud` (late apply rejections), and an all-ACTIVE sweep (PENDING fibers — cordis inject waiting has no timeout).
+
+**Boot glue is a class pair.** `AppCLIEntry` (apps/cli) and `AppWebEntry` (the shell kernel) hold only what must exist independently of cordis: argv facts, the composed patch set, the parsed boot manifest, the module system instance, loading-page handles — everything else lives in plugins. `AppCLIEntry.run()` is three stages: layered env (ambient > cwd `.env` > `$DSH_HOME/.env`, closing the defect above) → patch composition → Loader include boot plus the triple. `AppWebEntry.run()` mirrors it browser-side: parse `window.__DSH_BOOT__` into a `BootManifest` (two views: npm-package rows for the module table, cordis-plugin rows for entry composition; malformed wire throws), build the module system, render the loading page, prefetch the `immediately` tier in parallel with Context/Loader setup, **await the prefetch before creating entries** (materialization is `tree.import`'s synchronous require, unprotected by fiber inject waiting; cross-package require edges such as i18n → runtime/client need every immediately-tier factory registered first — an empirically found 10–25% boot race otherwise), adopt the modules entry, create the graph rows, settle, sweep.
+
+**Config sources have one declaration place each.** yml static values are engineering defaults; the profile json (`./.dsh-tmp-profile/config.json`, read-only, never created, cwd-anchored until the `$DSH_HOME` migration) is user config mapped through a static `PROFILE_MAPPINGS` table onto target rows (`provider`/`model` → the `api-gateway` row, `persistenceRoot` → the jsonl row); CLI flags map onto the `webserver` row with a field set disjoint from the json's; env values enter through yml `!!js` expressions, never through the mapping table. Patches replace a row's config wholesale, so the entry class re-reads the yml row's static values (bypass parse) and merges overrides on top. An unmapped json key fails loud. The resolved frontend `distIndex` rides the same patch channel — an assembly fact, not user config.
+
+**The transport splits five ways.** `dsh-host-apiproxy` upgraded to the gateway plugin (`api-gateway` row): default-exports `ApiProxyService`, config `{provider, model}`, provides `ctx.apiProxy`, transport-agnostic and registers no routes — `createApiProxy` moved here from the retired runtime package. `dsh-host-webserver` shrank to a plain route-registration plugin: `HttpServerService` provides `ctx.httpServer` (`register(route) → disposer` with duplicate-pattern throw, `tapIndex` transforms applied in registration order, `port`), listens on activation, per-request failures answer 400 and log without exiting, and knows no harness concepts. The connection node half owns the binding: it injects both services and registers `toFetchHandler(ctx.apiProxy)` under the `/api` prefix — future IPC carriers swap connection's transport while the gateway stays untouched. The modules node half (`ClientModuleHostService`, providing `ctx.clientModuleHost`) owns the graph: incremental per-package scanning (no full-rescan code path — `internal/plugin` marks the fiber's entry name dirty, a flush reconciles each name against live entries, package metadata including negative verdicts is cached forever, re-hashing is reachable only through `rebuilt(id)`), the bundle route, the index tap, and `onRebuilt`/`onGraphChanged` notification. The hmr node half owns dev reload: `fs.watchFile` stat-polling driven by `onGraphChanged` membership, and the `/plugins/events` SSE route.
+
+**Package export discipline.** The modules package exposes exactly `.` (node half) and `./client` (the complete browser half: `ClientModuleSystem`, `parseBootManifest`, the adoption plugin face) — no bespoke subpaths; wire types re-export through the root for host-side consumers. The adoption handshake: the kernel writes the constructed instance to `window.__DSH_MODULES__` before cordis exists; the `./client` apply reads the slot (missing = loud throw) and provides `ctx.modules`.
+
+## Consequences
+
+- Recomposing a web deployment is a yml/patch edit; the retired pieces (`mountWebPlugins`, `CLIENT_PACKAGES`, `createHostWebPluginRegistry`, `startWebServer`, the webserver's graph/SSE/api knowledge) are deleted.
+- Headless boots the same composition through the same entry (landed in the stacked follow-up): port 0 is its only surface difference, the model face gains `ask_user_question`/workspace context/model titles per the unification ruling, and `bootHost`/`startHost` retired with the `dsh-host-runtime` package. The profile write path, the `$DSH_HOME` profile relocation, and IPC carriers remain recorded deferrals.
+- A TypeScript pitfall worth remembering: a `declare module 'cordis'` augmentation in a file with **no cordis import** is demoted to a standalone module declaration and silently shatters the program-wide `Context` merge (`ctx.on`/`ctx.effect` vanish across the program). Anchor with `import type {} from 'cordis'`.
+
+## Alternatives considered
+
+| Rejected | One-line reason |
+|---|---|
+| Dedicated `dsh-host-profile` receiver package | The profile json is consumed at patch time; the only runtime consumer of `{provider, model}` is the gateway itself — its config is the receiver |
+| Runtime `assembly` shim plugin providing an `apiHandler` service | Existed only because `createApiProxy` lived in runtime; moving it into apiproxy made the gateway self-hosting, and `toFetchHandler` is a pure function the binding side calls |
+| Full-rescan + incremental scan coexisting | Two implementations, two semantics; the single per-package path covers the activation pass too |
+| A bespoke `./impl` export on the modules package | Non-uniform export surface; the standard `./client` carries the whole browser half |
+| dev overlay / `cordis.dev.yml` | One yml; `!!js` cannot conditionalize row existence, and `--dev` appending one row is the entire difference |
+| env vars in the mapping table | The same field would gain env/json double sourcing and need an invented precedence |
+| Unbarriered create-after-prefetch (`arrive()` dedup as safety) | Disproved by a 10–25% boot race: in-flight dedup covers same-package double-fetch, not cross-package synchronous require edges |
+| json file used directly as loader patches | json keys would couple to yml row structure; profile writers would need cordis knowledge |

+# Agent Note：dsh web 的 config-tree boot 与 web 传输分层
+
+Status: implemented
+
+[English](2026-07-24-web-config-tree-boot-and-transport-layering.md) | 中文
+
+> 范围：`dsh web` 如何组合（cordis.yml + cordis 之前的 boot 类 + 配置源），以及 web 传输如何跨包分层（网关 / 载体 / 绑定 / 图 / 开发期重载）。浏览器侧装载链归 [client 插件装载 note](2026-07-23-client-plugin-loading-model.md) 所有，本组合只是它的供给方。
+
+## 问题
+
+`dsh web` 曾是仅剩的手工装配面：`bootHost` 逐个挂 32 个插件、config 钉死在代码里（违反 no-hardcoded-tunables），client roster 是 `web.ts` 常量，而 TUI/headless 早已是 yml 组合。传输层的职责错位与之配套：webserver 自称哑载体却认识 `__DSH_BOOT__` 图、拥有 SSE 通道、硬编码 `/api/*` 前缀；dev 的 bundle watch 寄居在 prod registry 里靠 `watch?` 参数开关、生命周期无主；图 registry 对每次 `internal/plugin` 全量重扫；单请求失败与致命 server 错误共用一个一律退进程的 sink。还有一个用户可见缺陷：web 路径不装 `$DSH_HOME/.env`，`DSH_HOME=… dsh web` 读不到自定义 home 下的 API key。
+
+## 决策
+
+**组合是一棵平铺 config tree。** `apps/cli/cordis.yml` 持有全部行——host runtime（32 行）、`api-gateway` 行、`webserver` 行、`dshClient` 行（浏览器 roster；modules 行同时是 host 行）。不做 spine bundle：每插件一行、每个 config 字段 yml 可改。`--dev` 在 settle sweep 之前由代码追加 `dsh-client-hmr` 行——prod 与 dev 的全部差异就是这一行。行序无装载语义；激活由服务可用性驱动，boot 以 fail-loud 三件套补偿：`assertEntriesLoaded`（import 失败）、`installFailLoud`（迟到的 apply 拒绝）、all-ACTIVE sweep（PENDING fiber——cordis inject 等待没有超时）。
+
+**boot 胶水是一对 class。** `AppCLIEntry`（apps/cli）与 `AppWebEntry`（壳内核）只持有独立于 cordis 必须提前存在的东西：argv 事实、合成的 patch 集、解析出的 boot manifest、模块系统实例、loading 页句柄——其余一律进插件。`AppCLIEntry.run()` 三段：分层 env（ambient > cwd `.env` > `$DSH_HOME/.env`，顺手关掉上述缺陷）→ patch 合成 → Loader include boot 加三件套。`AppWebEntry.run()` 在浏览器侧镜像它：把 `window.__DSH_BOOT__` 解析成 `BootManifest`（双视角：npm 包行给模块表、cordis 插件行给 entry 组合；畸形 wire 大声抛）、建模块系统、渲染 loading 页、immediately 层预取与 Context/Loader 准备并行、**create entry 之前等预取齐**（物化是 `tree.import` 的同步 require，不受 fiber inject 等待保护；i18n → runtime/client 这类跨包 require 边要求 immediately 层工厂全部注册完——否则有实测 10–25% 的 boot 竞态）、收编 modules entry、逐图行 create、settle、sweep。
+
+**每个配置源有唯一声明位置。** yml 静态值是工程默认；profile json（`./.dsh-tmp-profile/config.json`，只读、绝不创建、暂锚 cwd 直至 `$DSH_HOME` 迁移）是用户配置，经静态 `PROFILE_MAPPINGS` 表映射到目标行（`provider`/`model` → `api-gateway` 行，`persistenceRoot` → jsonl 行）；CLI flags 映射到 `webserver` 行、字段集与 json 不相交；env 值经 yml `!!js` 表达式进入，绝不进映射表。patch 整体替换行 config，故 entry 类旁路 parse 重读 yml 行静态值再叠加覆盖。未映射的 json 键 fail loud。解析出的前端 `distIndex` 走同一 patch 通道——装配事实，不是用户配置。
+
+**传输五分。** `dsh-host-apiproxy` 升格网关插件（`api-gateway` 行）：默认导出 `ApiProxyService`，config `{provider, model}`，provide `ctx.apiProxy`，传输无关、不注册路由——`createApiProxy` 自已退役的 runtime 包迁入。`dsh-host-webserver` 缩成朴素路由注册插件：`HttpServerService` provide `ctx.httpServer`（`register(route) → disposer`、重复 pattern 即抛、`tapIndex` 按注册序应用、`port`），激活即 listen，单请求失败答 400 并记日志不退进程，不认识任何 harness 概念。connection node 半拥有绑定：inject 两个服务，把 `toFetchHandler(ctx.apiProxy)` 注册在 `/api` 前缀下——将来 IPC 载体只换 connection 的传输，网关零改动。modules node 半（`ClientModuleHostService`，provide `ctx.clientModuleHost`）拥有图：单包增量扫描（无全量重扫路径——`internal/plugin` 把 fiber 的 entry 名标脏，flush 逐名对账 live entries，包元数据含否定结论永久缓存，重哈希唯一入口 `rebuilt(id)`）、bundle 路由、index tap、`onRebuilt`/`onGraphChanged` 通知。hmr node 半拥有开发期重载：`fs.watchFile` stat 轮询、watch 集合跟随 `onGraphChanged`、`/plugins/events` SSE 路由。
+
+**包出口纪律。** modules 包只暴露 `.`（node 半）与 `./client`（完整浏览器半：`ClientModuleSystem`、`parseBootManifest`、收编插件面）——不设特设子路径；wire 类型经根出口 re-export 给 host 侧消费方。收编握手：内核在 cordis 之前把建好的实例写入 `window.__DSH_MODULES__`；`./client` 的 apply 读槽（缺槽大声抛）并 provide `ctx.modules`。
+
+## 后果
+
+- 重组一个 web 部署 = 改 yml/patch；退役件（`mountWebPlugins`、`CLIENT_PACKAGES`、`createHostWebPluginRegistry`、`startWebServer`、webserver 的图/SSE/api 知识）全部删除。
+- headless 已在 stacked 后续轮迁入同一组合同一入口：唯一面差异是 port 0，模型面按统一裁决获得 `ask_user_question`/workspace context/模型标题，`bootHost`/`startHost` 随 `dsh-host-runtime` 包退役。profile 写入路径、profile 迁 `$DSH_HOME`、IPC 载体仍为挂账项。
+- 一个值得记住的 TypeScript 坑：`declare module 'cordis'` augmentation 所在文件若**没有任何 cordis import**，会被降级成独立 module declaration，无声打散全程序的 `Context` merge（`ctx.on`/`ctx.effect` 全程序消失）。用 `import type {} from 'cordis'` 锚定。
+
+## Alternatives considered
+
+| 弃案 | 一行理由 |
+|---|---|
+| 专门的 `dsh-host-profile` 受体包 | profile json 在 patch 阶段消费完；`{provider, model}` 的唯一运行时消费方是网关自己——受体即网关 config |
+| runtime 里的 `assembly` 垫层插件（provide `apiHandler`） | 它的存在只因 `createApiProxy` 住 runtime；本体迁入 apiproxy 后网关自持插件身份，且 `toFetchHandler` 是绑定方自己调的纯函数 |
+| 全量重扫与增量扫描并存 | 两条实现两份语义；单包路径足以覆盖激活初扫 |
+| modules 包特设 `./impl` 出口 | 出口面不统一；标准 `./client` 承载完整浏览器半 |
+| dev overlay / `cordis.dev.yml` | 一套 yml；`!!js` 无法条件化行存在性，`--dev` 追加一行就是全部差异 |
+| env 进映射表 | 同一字段将出现 env/json 双源，需再发明优先级 |
+| create 不等预取（以 `arrive()` 去重为安全依据） | 被 10–25% boot 竞态证伪：在途去重只覆盖同包双拉，不覆盖跨包同步 require 边 |
+| json 直接当 loader patches 文件 | json 键名将耦合 yml 行结构，写入方要懂 cordis |

## Problem
-On Windows, creating the staging directory and temp file under the target's parent and relying only on inherited DACLs is sufficient for a new file, but not for replacing an existing file whose explicit or protected DACL is narrower than its parent: content is written under the broader parent DACL, and rename carries that staging descriptor onto the replacement.
+Atomic writes protect POSIX staging directories with `0o700` and temp files with `0o600`, but Windows mode bits expose only a synthetic read-only view of the actual DACL. Creating staging under the target's parent and relying on inheritance is sufficient for a new file, but not for replacing an existing file whose explicit or protected DACL is narrower than its parent: content is written under the broader parent DACL, and rename carries that staging descriptor onto the replacement.
## Decision
-`dsh-fs-local` reads an existing target's DACL with `GetFileSecurityW`, applies it to the empty temp file with inheritance protected before writing content, and publishes the closed temp with `ReplaceFileW`. The protected staging descriptor prevents the temp directory's inherited entries from broadening access; `ReplaceFileW` preserves the original target access policy and other replacement metadata. Its ACL merge may reserialize auto-inheritance state or duplicate equivalent ACEs, so self-relative descriptor buffers are not a stable equality contract. New files have no prior descriptor to preserve and continue to inherit the destination directory's DACL.

The coordinator independently asserts the returned id and compares the stored cwd with a live session's cwd before repair, state publication, or suffix persistence. It keeps a detached copy of validated metadata; JSONL append and repair derive their path from that copy.

+## Problem
+
+Providers occasionally return a degenerate completion: a well-formed stream that carries a terminal `stop` finish and zero content blocks — no text, no reasoning, no tool calls. If an adapter maps this shape to a successful `{kind: 'stop'}` finish, the loop logs an empty `assistant/message` and ends the turn as `completed`. Retry never runs, no failure reaches the caller, and a driver such as goal-session consumes a round without progress.
+
+## Decision
+
+An adapter classifies a completed empty response as a provider-boundary failure, and retry policy treats it as transient:
+
+- `dsh-llm` exports the canonical code `EMPTY_RESPONSE_CODE` (`'EMPTY_RESPONSE'`) beside `CONTEXT_WINDOW_EXCEEDED_CODE`/`QUOTA_EXCEEDED_CODE`.
+- `dsh-llm-pi-ai` (`mapStopReason`): a terminal `stop` whose assistant message has no content blocks becomes a `finish {kind: 'error'}` with that code. Context-overflow detection still wins where it applies (it is checked first and is the more actionable classification).
+- `dsh-llm-deepseek` (`translate`): at `[DONE]`, a `stop` (or absent) finish with no opened blocks becomes the same error finish. Reasoning-only streams count as content and stay successful.
+- `dsh-llm-retry` adds `EMPTY_RESPONSE` to `DEFAULT_RETRYABLE_CODES`: the attempt produced nothing durable, so repeating it is safe; deployments can still remove it via `retryableCodes`.
+
+Detection is scoped to `stop` finishes only. `max-tokens` with empty content keeps its existing meaning (pi-ai already normalizes the zero-output overflow case), `tool-calls` cannot be block-empty in practice, and error/aborted finishes already fail.
+
+The classification uses the existing loop machinery — `finishError` → `agent/request-error` → `dsh-llm-retry` — and keeps `agent-loop` provider-neutral. Exhausting the retry budget ends the turn with an explicit `EMPTY_RESPONSE` failure instead of an empty success.
+
+## Alternatives considered
+
+**Detect in the loop or `BlockAssembler`.** One shared implementation, but it moves provider-response judgment into the loop, against "plugins, not loop changes", and the assembler is a pure assembly algorithm. The adapter is where wire facts become harness classification, with the overflow reclassification as exact precedent.
+
+**A stream-transform plugin on the `llm/stream` waterfall.** Provider-neutral and one implementation, but it adds a package plus wiring for what is a boundary fact each adapter can state in a few lines, and default-on behavior would still require touching every bundle.
+
+**Treat whitespace-only or reasoning-only responses as empty too.** Rejected as overreach: those carry model-produced content, and misclassifying a legitimate (if useless) response as a transport-class failure risks retry loops on models that intentionally stop after reasoning. The scope is exactly "zero content blocks".
+
+## Consequences
+
+- A transiently misbehaving provider consumes a bounded retry instead of a turn with no output; a persistently empty model surfaces an actionable `EMPTY_RESPONSE` turn failure.
+- A model that genuinely intends to say nothing (rare, but possible after a tool result) is retried and, if consistently empty, fails the turn. This trade was accepted deliberately: an empty assistant message is indistinguishable from the provider defect and has no value to the user.
+- The `empty-response-retry` ACP snapshot (an authored keyless scenario with a deterministic 1 ms zero-jitter retry overlay, `examples/acp-agent/retry.cordis.yml`) pins the product-visible behavior: a durable `llm/retry` event, no ACP output for the discarded attempt, the recovered reply, and a clean completed turn.

+# Agent Note: Empty model completions are retryable EMPTY_RESPONSE failures
+
+Status: implemented
+
+[English](2026-07-24-empty-model-response-is-retryable.md) | 中文
+
+## Problem
+
+提供方偶尔会返回一种退化的 completion：流本身格式完好，携带一个终止性的 `stop` 结束，却没有任何内容块——没有文本、没有 reasoning（推理）、没有工具调用。如果适配器把这种形态映射为成功的 `{kind: 'stop'}` 结束，主循环就会记录一条空的 `assistant/message`，并把该轮次以 `completed` 结束。系统不会重试，失败也不会向调用方暴露，而像 goal-session 这样的驱动方会消耗一个轮次，却没有取得任何进展。
+
+## Decision
+
+由适配器把「已完成但为空」的响应归类为一次提供方边界失败，重试策略则将其视为瞬时性问题：
+
+- `dsh-llm` 在 `CONTEXT_WINDOW_EXCEEDED_CODE`/`QUOTA_EXCEEDED_CODE` 之外，导出规范代码 `EMPTY_RESPONSE_CODE`（`'EMPTY_RESPONSE'`）。
+- `dsh-llm-pi-ai`（`mapStopReason`）：当终止性 `stop` 所对应的 assistant 消息没有内容块时，它会变成一个携带该代码的 `finish {kind: 'error'}`。上下文溢出检测在其适用场景中仍然优先（它先被检查，也是更具可操作性的归类）。
+- `dsh-llm-deepseek`（`translate`）：在 `[DONE]` 处，若 `stop`（或缺失）结束且没有打开过任何块，则同样变成该错误结束。仅含 reasoning 的流算作有内容，仍视为成功。
+- `dsh-llm-retry` 把 `EMPTY_RESPONSE` 加入 `DEFAULT_RETRYABLE_CODES`：这次尝试没有产生任何持久内容，因此重复它是安全的；部署方仍可通过 `retryableCodes` 将其移除。
+
+检测仅限于 `stop` 结束。内容为空的 `max-tokens` 保持其既有含义（pi-ai 已经把零输出的溢出场景归一化处理），`tool-calls` 在实践中不可能是空块，而 error／aborted 结束本身已经算失败。
+
+这套归类使用既有的主循环机制——`finishError` → `agent/request-error` → `dsh-llm-retry`——并让 `agent-loop` 保持提供方无关。重试预算耗尽时，该轮次会以显式的 `EMPTY_RESPONSE` 失败结束，而不是在没有内容的情况下成功结束。
+
+## Alternatives considered
+
+**在主循环或 `BlockAssembler` 中检测。** 只需一份共享实现，但这会把对提供方响应的判断挪进主循环，违背「插件优先，而非改动主循环」，且 assembler 是纯粹的组装算法。适配器才是把协议层面的事实转化为 harness 归类的地方，而溢出重归类正是精确的先例。
+
+**在 `llm/stream` waterfall（瀑布式事件）上做一个流转换插件。** 这种做法提供方无关且只需一份实现，但它为「每个适配器几行就能声明的边界事实」额外增加了一个包和相应接线，而且默认开启的行为仍需改动每一个 bundle。
+
+**把仅含空白或仅含 reasoning 的响应也当作空响应。** 作为过度设计予以否决：这类响应携带了模型产生的内容，把一个合法（哪怕无用）的响应误判为传输类失败，会在那些故意在 reasoning 之后停止的模型上引发重试循环。其范围严格限定为「零内容块」。
+
+## Consequences
+
+- 一个偶发异常的提供方会消耗一次有界重试，而不是一个没有输出的轮次；一个持续返回空内容的模型则会暴露为用户可据以行动的 `EMPTY_RESPONSE` 轮次失败。
+- 一个确实打算什么都不说的模型（罕见，但在一次工具结果之后有可能出现）会被重试，若始终为空，则该轮次失败。这个取舍是经过审慎权衡后接受的：一条空的 assistant 消息与提供方缺陷无法区分，且对用户毫无价值。
+- `empty-response-retry` ACP 快照（一个人工编写的无密钥场景，配有确定性的 1 ms 零抖动重试 overlay，`examples/acp-agent/retry.cordis.yml`）钉住了产品可见的行为：持久的 `llm/retry` 事件、被丢弃的尝试不产生任何 ACP 输出、恢复后的回复，以及一次干净的已完成轮次。

+# Agent Note: Recursive Python SDK session notifications
+
+Status: implemented
+
+English | [中文](2026-07-24-recursive-python-sdk-session-notifications.zh.md)
+
+## Problem
+
+The Python SDK filtered turn notifications by comparing each payload directly with the root session id. This admitted a direct child's lifecycle because its parent id named the root, but rejected a grandchild's lifecycle and every descendant `session.event`. The JSON-RPC server still emitted those notifications, so they accumulated on the low-level global queue while high-level consumers lost nested trajectory relationships and completion states.
+
+## Decision
+
+`HarnessClient` records every valid `subagent.started` child-to-parent edge before dispatching the notification. A later `subagent.finished` routes by its immutable parent id but never rewrites current ancestry, so an older run that settles after its child id has been reused cannot displace the replacement session. Other session notifications resolve their session id by walking that client-lifetime ancestry graph to the requested root. The graph survives successive subscriptions so a descendant that outlives one `Session.run()` remains attributable when it emits during a later turn, and it resets when the client starts a new runtime process.
+
+`Session.run()` delivers the complete discovered session-tree notification stream through `TurnResult.notifications` and `on_notification`. Only `session.event` notifications whose `sessionId` equals the requested root enter `TurnResult.events` or final-response reconstruction. Descendant events are therefore observable without allowing a child response to replace the root response.
+
+## Alternatives considered
+
+**Add a root session id to every JSON-RPC notification.** The server already provides exact immediate-parent edges, and duplicating transitive ancestry on the wire would make every producer responsible for client subscription state.
+
+**Limit subagents to one level.** A deployment can set `maxDepth: 1`, but changing the SDK to depend on that policy would silently misreport valid recursive compositions.
+
+**Subscribe only to descendant lifecycle notifications.** This would repair relation and completion reporting, but descendant session events would continue accumulating on the global queue and callbacks would expose an incomplete tree.
+
+**Expose and index every subagent run id on the JSON-RPC wire.** Exact run identity is useful when a client must correlate two concurrent outcomes for the same child, but session-tree routing already has the authoritative start edge and each terminal notification's immutable parent. Expanding the protocol is unnecessary for this ownership decision.
+
+## Consequences
+
+High-level consumers receive nested lifecycle and session notifications in wire order while root turn results preserve their prior response semantics. The client retains one current parent entry per observed child until the runtime restarts; ancestry lookup is cycle-safe, and unrelated session notifications remain available through the global queue. Keyless Python tests cover two-level delegation, root-response isolation, absence of tree-notification queue buildup, ancestry reuse across subscriptions, and reused child ids whose older runs settle out of order.

+# Agent Note: Python SDK 递归会话通知
+
+Status: implemented
+
+[English](2026-07-24-recursive-python-sdk-session-notifications.md) | 中文
+
+## 问题
+
+Python SDK 过去通过将每条通知的 payload 与根会话 ID 直接比较来过滤轮次通知。直接子 agent 的生命周期通知因 parent ID 指向根会话而能够通过，但孙级生命周期通知与所有后代 `session.event` 都会被拒绝。JSON-RPC 服务器仍会发出这些通知，因此它们会堆积在底层全局队列中，而高层消费者会丢失嵌套轨迹的关系与结束状态。
+
+## 决策
+
+`HarnessClient` 会在分发通知前，记录每条有效 `subagent.started` 所包含的 child-to-parent（子到父）关系。后续的 `subagent.finished` 会依据自身不可变的 parent ID 路由，但不会改写当前祖先关系，因此旧 run 即使在其 child ID 已被复用后才结束，也无法覆盖替代它的新会话。其他会话通知会沿客户端生命周期内保存的祖先关系图回溯自身 session ID，判断它们是否属于请求的根会话。该关系图会跨连续订阅保留，因此某个后代即使跨过一次 `Session.run()`，在后续轮次中发出通知时仍能正确归属；客户端启动新的运行时进程时会重置关系图。
+
+`Session.run()` 通过 `TurnResult.notifications` 与 `on_notification` 提供已发现会话树的完整通知流。只有 `sessionId` 等于请求根会话的 `session.event` 才会进入 `TurnResult.events` 或参与最终回复重建。因此调用方能够观察后代事件，同时子会话回复不会覆盖根会话回复。
+
+## 考虑过的替代方案
+
+**在每条 JSON-RPC 通知中加入根会话 ID。** 服务器已经提供精确的直接父子关系；在线路协议中重复传递祖先关系，会迫使每个生产者承担客户端订阅状态的职责。
+
+**把 subagent 限制为一层。** 部署可以设置 `maxDepth: 1`，但让 SDK 依赖该策略，会对合法的递归组合产生静默误报。
+
+**只订阅后代生命周期通知。** 这可以修复关系与结束状态的上报，但后代会话事件仍会堆积在全局队列中，回调看到的会话树也不完整。
+
+**在 JSON-RPC 线路上公开并索引每个 subagent run ID。** 当客户端必须关联同一 child 的两个并发结果时，精确 run 身份很有价值；但会话树路由已经拥有权威 start 关系和每条终止通知中不可变的 parent。没有必要为这一归属决策扩展协议。
+
+## 后果
+
+高层消费者会按线上的原始顺序收到嵌套生命周期与会话通知，同时根轮次结果保持原有回复语义。客户端会为每个已观察到的子会话保留一条当前父关系，直到运行时重启；祖先回溯能够安全处理环，无关会话通知仍可从全局队列获取。无密钥 Python 测试覆盖两层派生、根回复隔离、会话树通知不堆积、跨订阅复用祖先关系，以及旧 run 乱序结束的复用 child ID。

-# Agent Note: Agent Client Protocol (ACP) support — drive the coding agent from external editors
-
-Status: implemented
-
-## Problem
-
-The harness originally exposed agents only through a readline loop. That surface could carry text, but it gave an editor no structured way to create or resume sessions, correlate prompt completion, stream reasoning and tool activity, render tool-specific UI, ask for permission, or cancel one conversation without disturbing another. ACP defines those interactions as JSON-RPC over stdio, and Zed is the target client used to make concrete compatibility decisions.
-
-The bridge must preserve the harness's existing ownership boundaries. It cannot depend on the concrete agent loop, bypass the tool registry, execute shell commands in the editor, or invent a second source of session truth. stdout is also the protocol transport, so any accidental log output corrupts the connection.
-
-## Decision
-
-`@deepseek-ai/dsh-acp` is a UI/client-driver plugin under `packages/ui/acp`. It uses `@agentclientprotocol/sdk`'s `AgentSideConnection` over stdin/stdout and programs only interface services: the agent create/resume factory, session persistence, tool registry, user interaction, and optional approval/bash capabilities. It does not change the agent loop and is not a capability-seam implementation.
-
-The bridge implements the following stable session path:
-
-- `initialize` negotiates the protocol version, advertises text plus `resource_link` prompts, and advertises `loadSession`.
-- `session/new` validates an absolute `cwd`, stores it in `SessionHeader`, creates an agent through `ctx.agents`, and returns any composition-backed config options.
-- `session/load` validates the requested cwd against persisted metadata before constructing an agent, reserves the id across the asynchronous resume, replays user/assistant/tool events as ACP updates, and reports the resumed config-option fold.
-- `session/prompt` accepts text and resource links, rejects unsupported or empty content, allows one in-flight prompt per session, and settles against that prompt's owning `turn/end`. An error turn rejects the RPC; other closed turn reasons map through a total ACP stop-reason codec.
-- `session/cancel` calls the queue-aware agent cancel path and settles only the addressed session's prompt.
-
-Tool-call presentation remains tool-owned. A tool's `presentCall` and `presentResult` return the `generic`, `terminal`, or `diff` render-intent variants; the bridge switches on that union and maps it to ACP. Presenter-less tools receive a generic fallback. Bash terminal cards use Zed's capability-gated `_meta.terminal_info`, `_meta.terminal_output`, and `_meta.terminal_exit` convention; the harness still executes the command through `ctx.bash`, preserving sandbox, environment scrub, ownership, and cwd. Clients without that extension receive ordinary text content. Filesystem tools provide diff cards and file locations without hard-coded tool-name branches in the bridge.
-
-Permission handling is an answerer on the [user-approval seam](2026-07-06-approval-seam.md), not an ask-every-tool policy in ACP. An `approval/request` for a bridge-owned agent with a call id becomes `session/request_permission` on that agent's editor session, with one-shot allow/reject choices. Foreign or call-less requests delegate; a missing or failed answerer remains fail-closed. The plugin that asks—such as a pre-execute policy or bash escalation—owns the decision to ask.
-
-When `ctx.permission` is composed, the bridge exposes one `permission` select from the deployment's preset table. The shipped `workspace-write` and `danger-full-access` presets each bundle a sandbox mode with an approval policy; unmatched effective knobs produce the switch-away-only `custom` state. `session/set_config_option` validates through `PermissionService.set()` and writes both owning knob events. A switch during an open turn appends immediately; an idle switch is overlaid in responses and anchored at the next `agent/prompt-submit`, before request assembly. Until then it is memory-only, so a crash restores the durable fold. ACP session modes are not modeled because config options are the forward protocol surface; `AcpConfig.model` remains connection-wide.
-
-The bridge also provides the ACP-backed `UserInteractionProvider`: `ask_user_question` requests become form elicitations on the owning session. Select, multi-select, option descriptions, and custom-answer override semantics are preserved.
-
-Lifecycle ownership is explicit. The bridge holds an `AgentHandle` per live session. Disconnect and Cordis disposal cancel pending prompts, dispose every handle in parallel, await loop quiescence and persistence flush, and then remove the records. Stream notification failures are contained so a vanished client cannot corrupt an agent turn. The ACP app composition loads no stdout logger; a test guards stdout as framed JSON-RPC only.
-
-The precise supported and deferred protocol rows live in [`packages/ui/acp/acp-feature-support.md`](../../../../packages/ui/acp/acp-feature-support.md); the package README is the operational contract.
-
-## Alternatives considered
-
-**A prepended `tools/execute` listener that asks on every ACP-owned call** — rejected. It would hard-code permission policy into the UI bridge, ask even when no policy requires it, and could not serve approval requests that arise after execution begins. The shared user-approval seam keeps mechanism, asking policy, and UI answerer separate.
-
-**Inject the concrete `agentLoop`** — rejected. Agent creation, resume, idle observation, and disposal are interface-level ownership operations on `dsh-agent`; a UI plugin does not need a dependency-rule exception.
-
-**Execute bash through ACP `terminal/*`** — rejected. That would move execution outside the harness and bypass its sandbox, credential scrub, task ownership, cwd resolution, and session log. Terminal metadata is presentation only.
-
-**Represent permission presets as ACP session modes** — rejected. The deployment-defined preset is already one config-option select, while session modes are the legacy surface slated for removal in ACP v2.
-
-**Hijack stdout defensively** — rejected. Process-wide monkey-patching is outside Cordis effect ownership and races the protocol transport. The app composition owns stdout purity.
-
-## Consequences
-
-Editors can create, load, prompt, cancel, render, ask, and reconfigure multiple harness sessions over one ACP connection without a loop-specific dependency. The session event log remains the durable source for replay, prompt settlement, cwd, and per-session configuration. Tool presentation and human-answer channels remain extensible plugin contracts instead of ACP-specific behavior.
-
-The bridge deliberately does not implement session list/delete/resume/close capabilities, MCP passthrough, additional directories, image/audio/embedded-resource prompts, plans, slash commands, usage updates, editor filesystem delegation, or the ACP terminal execution sub-protocol. Runtime model selection was added later through standard session config options by the [LLM catalog and ACP selection Agent Note](../architecture/2026-07-15-llm-model-catalog-and-acp-selection.md).
-
-An idle config selection is truthful in the live response but not durable until the next `agent/prompt-submit` anchors it inside the open turn. Crashing before that boundary loses the pending selection; this is the cost of keeping session events turn-enclosed and replay-safe.
-
-## Verification
-
-The ACP suites cover the in-memory protocol codec, create/load replay, exact prompt settlement, cancellation races, unsupported content, tool presentation, terminal capability fallback, permission outcome mapping, config-option validation and persistence, multi-session isolation, disconnect/disposal quiescence, and HMR cleanup. Snapshot and built-bin tests exercise the app composition, while the real-API e2e self-skips without a key.

+> Written when ACP was an editor bridge, motivated by Zed's multi-session client model. [ACP as an automation-only protocol](../simplification/2026-07-23-acp-automation-only-protocol.md) removed the editor surfaces; the multiplexing decision itself is unchanged and this note now states it against the automation contract.
+
## Problem
-An ACP editor can keep several conversations alive over one agent subprocess. A single-active-session bridge would force extra processes and would not match Zed's client model, which tracks multiple session ids and concurrent loads. Multiplexing introduces isolation risks: events, prompt completion, cancellation, permission prompts, config selections, and predictable background-task ids must never cross session boundaries.
+An ACP automation client can keep several conversations alive over one agent subprocess. A single-active-session bridge would force extra processes and prevent one parent controller from driving independent children over one connection. Multiplexing introduces isolation risks: committed answers, prompt completion, cancellation, permission requests, and predictable background-task ids must never cross session boundaries.
## Decision
-The ACP bridge stores live sessions in `Map<SessionId, SessionRecord>`. Agent-scoped callbacks use `ownedRecord`: look up `agent.session.id` in that forward map and accept the record only when it owns the exact agent object, so a foreign same-id object cannot claim the session. A record owns its agent handle, in-flight prompt, live tool-call presentation state, pending idle config switches, session cwd, and client capability snapshot. A separate loading-id set reserves each id before asynchronous resume so two pipelined loads cannot construct duplicate agents; distinct ids may load concurrently.

Agent-scoped callbacks use `ownedRecord`: look up `agent.session.id` in that forward map and accept the record only when it owns the exact agent object, so a foreign same-id object cannot claim the session. A record owns its agent, exact disposer, and optional in-flight prompt with the durable turn number that eventually settles it. The session header owns its cwd; the bridge keeps no parallel workspace or client-capability state.
-Every `session/event` and `agent/status` callback resolves the owning record before sending or settling anything. Each session permits one in-flight prompt independently. The prompt records a log watermark, captures its own `turn/start`, and settles only on the matching `turn/end`; a late end from a cancelled prior turn cannot resolve a newer prompt. `session/cancel` addresses one record and calls only that agent's queue-aware cancel path.

-Permission ownership uses the same exact-agent check against the forward map. The ACP `approval/request` answerer prompts only the editor session that owns the requesting agent and delegates foreign requests. User-interaction elicitations likewise route by agent ownership. Per-session sandbox and approval config values fold only that session's events, with pending idle switches stored on that record until the next turn anchors them.

The ACP `approval/request` answerer sends a one-shot machine-policy request only for the session that owns the requesting agent and delegates foreign or call-less requests. The bridge has no elicitation, config-selection, or other human-interaction state.
-Background bash tasks carry an opaque owner token equal to the owning session id. `bash_output` and `bash_kill` compare the caller's token with the executor's task ownership before reading or killing; a predictable task id alone grants no access. Ownership is stored with the executor task, so a tool plugin reload does not erase it.

Connection teardown clears the live map, settles each pending prompt as cancelled, and disposes all `AgentHandle`s in parallel.

+# Agent Note: 在单个连接上多路复用并发 ACP 会话
+
+Status: implemented
+
+[English](2026-06-14-acp-multi-session.md) | 中文
+
+> 本 Agent Note 写于 ACP 还是编辑器桥接层的时期，动机来自 Zed 的多会话客户端模型。[ACP 作为仅面向自动化的协议](../simplification/2026-07-23-acp-automation-only-protocol.md)移除了编辑器接口；多路复用决策本身不变，本 Agent Note 现依照自动化契约陈述它。
+
+## 问题
+
+一个 ACP（Agent Client Protocol）自动化客户端可以在同一个 agent（智能体）子进程上保持多个对话。如果桥接层只支持单活跃会话，就不得不启动额外进程，也会阻止一个父控制器通过一条连接驱动多个独立子任务。多路复用引入了隔离风险：已提交的回答、提示词完成、取消、权限请求以及可预测的后台 task id 绝不能跨越会话边界。
+
+## 决策
+
+ACP 桥接层将活跃会话存储在 `Map<SessionId, SessionRecord>` 中。agent 作用域的回调使用 `ownedRecord`：在正向 map 中查找 `agent.session.id`，且仅当该记录拥有精确的 agent 对象时才接纳它，使外部的同 id 对象无法冒领会话。一条记录拥有其 agent、精确的释放器，以及可选的进行中提示词和最终结算它的持久轮次号。会话 header 拥有其 cwd；桥接层不保留平行的工作区或客户端能力状态。
+
+每个 `session/event` 回调在发送或结算任何内容之前，先解析出所属记录。每个会话独立允许一个进行中的提示词。提示词捕获自己源自用户消息的 `turn/start`，并仅在匹配的 `turn/end` 到达时结算；注入轮次、插件或 goal 的自主轮次，以及来自已取消的前一轮次的迟到 end 都不能 resolve 它。`session/cancel` 定位到一条记录，只调用该 agent 的队列感知取消路径。
+
+权限归属使用对正向 map 的同一精确 agent 检查。ACP `approval/request` 应答器只为拥有发起请求的 agent 的会话发送一次性机器策略请求，并将外部请求或不带 call id 的请求委托出去。桥接层没有表单引导、配置选择或其他人机交互状态。
+
+后台 bash 任务携带一个不透明的 owner token，其值等于所属会话 id。`task_output` 和 `task_kill` 在读取或终止之前，将调用方的 token 与执行器的任务归属进行比较；仅凭可预测的 task id 不能获得访问权。归属信息与执行器任务一起存储，因此工具插件重载不会擦除它。
+
+连接拆除时清空活跃 map，将每个待处理的提示词以取消状态结算，并并行 dispose（资源释放）所有 `AgentHandle`。每个句柄停止并等待其循环完成、在仍然附着时刷新会话、注销 agent 并移除会话。拆除操作被 memoize 化，由客户端断连和插件 dispose 共享。
+
+## 协议与工作区作用域
+
+[ACP v1 明确允许一个连接上存在多个并发会话](https://github.com/agentclientprotocol/agent-client-protocol/blob/01beb5fb5eec60e9f516a80d85eb03594bac61e3/docs/get-started/architecture.mdx#L16-L24)，每个新会话都携带自己的主 `cwd`。本桥实现该会话级多路复用，其中包括[按会话 cwd 决策](../architecture/2026-07-02-fs-per-session-cwd.md)所记录的不同主工作区；它不会为每个会话创建一个 agent 子进程。
+
+一个会话内部的多根项目是另一项可选能力：ACP 把[有效根目录定义为主 `cwd` 加 `additionalDirectories`](https://github.com/agentclientprotocol/agent-client-protocol/blob/01beb5fb5eec60e9f516a80d85eb03594bac61e3/docs/protocol/v1/session-setup.mdx#L313-L367)。自动化桥接层不公布任何多根能力，并拒绝非空的 `additionalDirectories`；如[包契约](../../../../packages/acp/acp/README.md#protocol-contract)所记录，每个全新会话恰好有一个工作区。
+
+[标准传输是每个 stdio 连接一个 agent 子进程](https://github.com/agentclientprotocol/agent-client-protocol/blob/01beb5fb5eec60e9f516a80d85eb03594bac61e3/docs/protocol/v1/transports.mdx#L17-L42)；多个连接因此需要多个子进程或自定义传输，而本决策保证的是一个连接内部存在多个会话。在该连接内，`ctx.sandboxPolicy` 把每个会话的 `cwd` 解析为其自己的 `workspace-write` 根目录，因此共享的 bash 和文件系统服务可以服务并发项目而不授予跨项目写入。这不会添加 ACP `additionalDirectories`；它只是从已经支持的「每会话一个主根目录」路径中移除了进程级根目录限制。
+
+## 曾考虑的替代方案
+
+**每连接单活跃会话**：否决。增加进程开销，并阻止程序化的父控制器多路复用可独立取消的工作。
+
+**每会话 `ctx.extend()`**：否决。子上下文本身不会创建子插件 fiber，因此监听器仍属于桥接层 fiber。实际实现的桥接层使用全局监听器加显式 O(1) 解复用，以及每会话拥有的记录；agent 生命周期由 `AgentHandle` 管理。
+
+**以 Agent 对象标识作为 bash 任务归属**：否决。恢复或替换后的 agent 对象可能合法地代表同一个持久会话。不透明的会话 token 才是跨边界的标识，应当在插件重载后仍然存活。
+
+## 后果
+
+N 个会话可以并发地返回已提交的回答、提交提示词、请求权限和运行后台任务，而不会交错或跨会话结算。一个会话中的取消不影响相邻会话。桥接层为此付出了显式 map 和隔离测试的代价，但它不会为每个会话添加一组监听器，从而避免了长连接期间的监听器扇出。
+
+桥接层不暴露独立关闭单个活跃会话的协议方法。所有记录在连接拆除时一起离开；会话导航与恢复属于 host API，而非这个自动化协议。
+
+## 验证
+
+多会话测试套件通过按路由投递的已提交回答、独立的进行中提示词、定向取消以及共享拆除来驱动并发会话；审批与输出边界套件覆盖权限路由和精确 agent 拒绝。工具 bash 测试证明一个会话无法读取或终止另一个会话的后台任务。

## Problem
In the registry's native presentation, the agent loop advertises every visible capability as a JSON-schema function definition. `ToolRegistry` contributes its schemas to the system-prompt assembly, the assembly's `tools` land on the wire (and in the logged request header), the model invokes one `tool-call` block per step, and the loop dispatches each call through `ctx.tools.execute()` **sequentially** (parallel tool execution is an explicit open TODO in `dsh-tools` and [docs/architecture.md](../../../../docs/architecture.md)), with **every** intermediate `tool-result` re-entering the model's context on the next request.

+# Agent Note: Code Mode——模型针对工具注册表编写 TypeScript
+
+Status: implemented
+
+[English](2026-06-15-code-mode.md) | 中文
+
+## 问题
+
+在注册表的原生呈现方式下，agent loop（智能体循环）将每个可见能力以 JSON Schema 函数定义的形式通告给模型。`ToolRegistry` 将其 schema 贡献给系统提示词组装，组装结果中的 `tools` 落到协议格式（wire format）上（也记录在请求头日志中），模型每步调用一个 `tool-call` 块，循环通过 `ctx.tools.execute()` **逐个**分发每次调用（并行工具执行是 `dsh-tools` 和 [docs/architecture.md](../../../../docs/architecture.md) 中明确标注的 open TODO），且**每一个**中间 `tool-result` 都会在下一次请求时重新进入模型上下文。
+
+对于多步工具操作，这种方式 token 开销大且串行。模型无法组合工具——遍历结果集、根据中间值分支、扇出、后处理——每次调用都需要一次完整的模型往返，而每次往返都会把完整的中间结果拖回上下文，不管模型是否需要。
+
+Cloudflare 的 [Code Mode](https://blog.cloudflare.com/code-mode/) 提出了一种替代方案，基于一个简单的观察：LLM（大语言模型）编写代码的能力优于发出工具调用，因为它们见过数百万行真实代码，而人为构造的工具调用 trace 相对很少。模型不再每步发出一次工具调用，而是针对工具生成的 API 编写一段 TypeScript 程序，程序在沙箱运行时中执行，模型只策展返回的内容——仅限它 print 或 return 的部分——而非所有中间结果。
+
+工具呈现属于掌管工具可见性的注册表：如果把第二种呈现方式实现为事后的 waterfall（瀑布式事件）变换，正确性将依赖监听器顺序，并与[可重建请求](../architecture/2026-07-05-reconstructable-requests.md)冲突。执行基底同样属于基础设施而非占位实现：Node `worker_threads` 提供独立 isolate、空环境、堆上限以及对热同步循环的终止能力，同时契合 harness 既有的信任模型（§信任姿态）。
+
+## 决策
+
+三项决策，各自在下方独立小节中展开：
+
+1. **Code Mode 是 `ToolRegistry`（`dsh-tools`）的一等呈现模式**，通过经校验的 `mode` 配置选择：`'native'`（默认，贡献可见能力 schema）、`'code'`（注册表仅贡献其保留的 `run_code` 传输通道加一份生成的 SDK `.d.ts` 到系统提示词中）或 `'both'`（原生 schema 加传输通道 + SDK）。注册表在源头塑造其权威贡献；协作式提示词组装的结果仍具权威性，记录在日志中的请求头精确反映该返回的呈现。
+2. **代码执行是一个能力 seam**——`packages/code-runtime/` 包含接口包 `@deepseek-ai/dsh-code-runtime`，拥有 `ctx.codeRuntime`（[能力 seam](../architecture/2026-06-13-capability-seams.md)；消费方 = `dsh-tools`，core 消费 seam 的先例见 `agent-loop` → `dsh-llm`）。运行时对工具一无所知：它接收一段程序和命名的异步绑定，执行程序，报告 `{ value, logs, error? }`。语言和基底是后端属性，因此未来的 Python 或容器后端只是另一个实现包，而非重新设计。
+3. **交付的实现是 `@deepseek-ai/dsh-code-runtime-worker`**：每次运行 spawn 一个全新的 Node worker 线程，对模型的 TypeScript 进行 type-strip 后执行，绑定通过消息端口桥接，环境为空，堆/输出/时间上限可配置，并支持硬终止。其信任姿态在设计上等同于 bash——无需 unsafe-acknowledgement flag——因为 harness 已经交付了 `dsh-bash-local`，后者以严格*更高*的环境权限执行模型编写的任意 shell 命令。
+
+本说明负责定义 Code Mode 的呈现、组合、隔离与结算基础。后续的[类型化工具返回值 Agent Note](2026-07-20-code-mode-typed-tool-returns.md)负责定义生成的输出映射、规范绑定值、`ToolCallError` 和无损外层输出边界。
+
+### 注册表拥有模式
+
+`ToolRegistry` 获得一个经 schemastery 校验的配置（`static Config`），这是它的第一个配置：`mode: 'native' | 'code' | 'both'`，默认 `'native'`。部署通过 `cordis.yml` 翻转模式（`tools: { mode: code }`），无需改代码，遵循 no-hardcoded-tunables 约定。
+
+**协议工具列表。** 注册表在 `'native'` 下贡献可见能力，在 `'code'` 下仅贡献 `run_code`，在 `'both'` 下两者都贡献。最终的 `PromptAssembly.tools` 列表记录在请求头中。`run_code` 是一个保留的呈现传输通道，位于注册和限制层之外；直接提示词提供方和组装 waterfall 仍各自负责自己的贡献。
+
+**与 `toolOrder` 的交互，预先说明：** 如果配置的 `systemPrompt.toolOrder` 引用了原生能力名称，在 `mode: 'code'` 下会拒绝所有组装，因为那些名称不在该模式的协议校验范围内。这是正确行为而非 bug：使用 Code Mode 的部署需要更新其 order 配置或移除它。
+
+**SDK 提示词段。** 在 `'code'` 和 `'both'` 下，tool-guidance order band 中的惰性 `tools:sdk` 段为当前 scope 的可见能力渲染 TypeScript 声明加固定的使用说明。它共享查找和执行可见性，排除 `run_code`，并按字典序排列工具以获得字节稳定的输出。
+
+**组装所有权。** `run_code` 和 `tools:sdk` 作为正常的组装输入进入受信任的 `system-prompt/assemble` waterfall。一个 scoped 的 `tools:sdk` 段可以在分发前遮蔽全局默认值，监听器也可以移除或替换任一贡献。waterfall 返回的组装结果是最终的，因此修改这些输入的人有责任在部署期望 Code Mode 可用时保持协议面的完整性；没有恢复 pass 会覆盖有意的组合。
+
+**代码生成。** `jsonSchemaToTs()` 将 `defineTool` 的 JSON Schema 子集映射为 TypeScript，将 schema 描述带入 JSDoc，不支持的构造降级为 `unknown`。SDK 将工具暴露为带引号的对象键，支持任意名称而无需别名或冲突处理。类型是建议性的，因为运行时在执行前会剥离类型。
+
+### run_code 工具与分发桥
+
+在 `'code'` 和 `'both'` 下，注册表拥有 `run_code` 作为保留的呈现传输通道，带一个必需参数 `{ code: string }`。它由一个正常的 `ToolDefinition` 表示以供分发，但位于可过滤的能力层之外，因此限制规则不会意外移除 Code Mode 的唯一入口。调用遍历完整的工具流水线——`tools/pre-execute` → 单调守卫 → `tools/execute` 包裹分发 → `tools/post-execute` → 由定义拥有的可选 `finalizeContent` → 不可变的 `tools/result` 通知——与原生调用完全一致；权限插件可以在程序运行前检查程序文本，最终结果观察者看到的是规范化的外层结果。其 `execute(args, exec)`：
+
+1. **构建绑定。** 一个 run 级别的 signal 跟随外层取消，并在 run 结算时被 abort。每个可见工具绑定都会对无损 JSON 参数创建快照，等待序列化队列，以确定性的 call id 和外层 token 作为 `parent` 执行，通过外层 execution 延后返回的上下文，并记录 `tool/code-dispatch`。成功时返回工具最终的规范 JSON 值；失败则变为程序可见的 `ToolCallError`。每个子调用保留自己不可变的执行标识，并遍历完整的工具流水线。
+2. **运行程序**：`ctx.codeRuntime.run({ program: args.code, bindings: [{ global: 'tools', functions }], signal: runController.signal })`。运行时接收的是 run 级别的 signal 而非仅调用方的外层 signal，因此外层 run 以任何方式结算都会同时 abort 运行时内部的工作。
+3. **完全停稳后结算。** 运行时结算后，桥 abort 未完成的工作并排空分发队列后再返回。成功时返回捕获的日志和完成值，将其作为规范输出；注册表再把该值渲染为持久化的 `tool/result.content`，供结果卡片直接读取。运行时失败变为 `CodeRunFailedError`；后端拒绝使用注册表的正常错误边界。两者都产生结构化的错误结果，且 `run_code` 结算后不允许子调用追加。
+
+**子调用上下文通过父调用延后。** 在 `run_code` 内部注入会破坏父调用/结果的相邻性，因此 `ToolRunContext.deferContext()` 按分发顺序收集每个子结果的 `additionalContexts` 条目。即使程序后来抛出异常，注册表仍携带该数组；循环只在外层结果与步骤中所有兄弟结果之后追加每个条目。外层 post-execute 阻止会丢弃工具延后的条目，只暴露阻止 decision 显式附加的上下文。
+
+**并发被序列化。** 每次 run 拥有一个分发队列，因此即使 `Promise.all` 也按提交顺序执行工具调用。结算时放弃尚未开始的排队调用。并行化需要每个工具的并发安全元数据。
+
+**呈现。** `run_code` 的 render intent 按[呈现意图 Agent Note](../architecture/2026-07-02-tool-render-intent-union.md)在此决定：`presentCall` 创建一个 `generic` 卡片，`kind: 'execute'`，以程序文本作为标题，并将同一程序文本作为 `rawInput`；`run_code` 有意不声明 `presentResult`，因此 TUI 和宿主/客户端运行时（Web）会通过通用原始内容回退机制，使用最终持久化的 `tool/result.content` 补全该卡片，其中包括捕获的日志，以及返回值、失败信息或 post-policy 输出落盘预览。这不是 `terminal` 卡片：该卡片的语义是「工作目录中的 shell 命令」，程序不是。参见[结果卡片完整性说明](../bug-fix/2026-07-20-code-mode-result-card-completeness.md)。
+
+### 可观测性：`tool/code-dispatch`
+
+每次子分发追加一个仅日志的 `tool/code-dispatch` 事件，包含父子 call id、工具标识、规范化参数和结果摘要。它不进入模型历史，但可供持久化和 UI 使用。追加发生在开放的 `run_code` 轮次内。没有 agent 的直接执行仍然运行，但无法记录该事件。
+
+### code-runtime seam
+
+`packages/code-runtime/code-runtime/`——`@deepseek-ai/dsh-code-runtime`，仅依赖 `cordis`。一个抽象的 `CodeRuntime extends Service`（`super(ctx, 'codeRuntime')`）加上词汇：
+
+- `CodeRunRequest = { program: string; bindings: CodeBindingNamespace[]; signal?: AbortSignal }`
+- `CodeBindingNamespace = { global: string; functions: Record<string, (args: unknown) => Promise<CodeJsonValue>>; errorClass?: { name: string; memberNameProperty: string } }`——运行时将每个命名空间作为程序内部的全局异步函数对象暴露；可选描述符要求运行时注入真正的、程序可见的 reject 类，而无需让 seam 获知消费方专用名称。`CodeJsonValue` 是这个低依赖 seam 的结构化无损 JSON 类型，因此绑定参数与解析值可以完整跨越实现的序列化边界。
+- `CodeRunResult = { value?: CodeJsonValue; logs: string[]; error?: CodeRunFailure }`——程序执行失败时，执行 promise 仍会 fulfill，并通过 `error` 字段返回失败结果。只有调用方/seam 误用（例如重复的绑定命名空间）时，`run()` 才会 reject；消费方仍在自己的错误边界处理不合规后端的拒绝。
+- `CodeRunFailure = { kind: 'exception' | 'timeout' | 'abort' | 'worker-exit' | 'invalid-output' | 'output-limit'; message: string }`——按[防御性模式](../../../../docs/defensive-patterns.md)独立报告的正交结果；超时的 run 不是异常，abort 不是超时，有损完成值不是溢出，基底退出也与上述情况相互独立。
+- 两个只读的后端描述符，仅供信息参考而非门禁判定：`language`（程序必须使用的语言——交付的后端为 `'typescript'`；Python 后端会声明自己，并在呈现侧配对自己的 SDK 生成器）和 `isolation`（交付的后端为 `'worker-thread'`；未来可为 `'process'`、`'container'` 等）。`dsh-tools` 在 MVP 中要求 `language === 'typescript'`——其代码生成输出 TS——否则组装会大声失败，与 `toolOrder` 违规时的配置错误惯用法相同（如 `mode` 为非 native 但根本没有加载 `ctx.codeRuntime`）。

+请求包含所有运行时输入；实现方拥有经校验的超时和上限默认值。注册表仅在组装 Code Mode 时查找可选的运行时，因此 native 模式不依赖它。缺失或语言不兼容的运行时会大声失败。替代基底或语言可以在同一 seam 背后替换实现，配对相应的 SDK 生成器。
+
+### worker-thread 运行时
+
+`@deepseek-ai/dsh-code-runtime-worker`，`packages/code-runtime/` 组的第二个包（package）。每次 `run()`：
+
+1. **宿主侧 type-strip**，使用 Node 内置的 `stripTypeScriptTypes`（`node:module`；在本仓库的整个引擎范围 `^22.19.0 || >=24.0.0` 内可用，且保持位置不变，因此运行时错误行号与模型源码一致）。仅剥离模式拒绝不可擦除的语法（`enum`、namespaces）——该拒绝以 `error.kind: 'exception'` 加 Node 的消息返回，SDK 说明写明「仅限可擦除 TypeScript」，模型像处理其他程序错误一样自我修正。语法级失败不会 spawn worker。
+2. **每次 run spawn 一个全新 `Worker`**，来自包自身的 bootstrap 模块：`env: {}`（真正为空——比 spawn 命令的 scrubbed-env 规则更严格），`resourceLimits` 来自配置，`stdout`/`stderr` 捕获到 `logs` 而非继承。不做池化，不跨 run 保留状态：程序的世界随 worker 消亡，这使得 run 仅从日志即可重建，状态泄漏不可表达。
+3. **在 bootstrap 中执行**：剥离后的程序成为一个 `AsyncFunction` 的函数体，其参数是绑定全局变量、消费方声明的 reject 类和一个捕获式 `console` shim，因此顶层 `await` 和 `return` 可用。Code Mode 声明 `ToolCallError`，成员属性为 `toolName`；运行时无需硬编码工具即可实体化真正的构造函数。无损 JSON 完成值会精确跨越边界；`undefined` 仍表示缺席，有损值产生 `invalid-output`，过大的外层结果产生 `output-limit`，而不会退化为检查格式化后的字符串替代品。
+4. **通过消息端口桥接绑定**：worker 中的每个绑定函数发送 `{ id, global, name, args }` 并等待回复；宿主根据请求的绑定校验名称、调用、并回复 `{ id, ok, value }` 或 `{ id, ok: false, message }`（宿主侧绑定拒绝变为程序侧 rejection）。worker 侧的命名空间对象通过 `defineProperty` 构建为 null-prototype，因此名为 `__proto__`、`constructor` 或 `toString` 的绑定是普通自有属性，而非原型链碰撞。未知名称、重复 id 和结算后消息被拒绝或忽略——端口协议假设对端是恶意的，因为对端运行的是模型代码。
+5. **强制独立预算。** `computeMs` 计量 worker 忙碌时间，允许慢速的 awaited 工具而不放过热循环。`maxWallMs` 约束总经过时间，包括未解析的等待。`maxOutputBytes` 只约束序列化后的外层日志、完成值或诊断的组合；中间绑定值没有字节数上限。到期、取消和完成都终止 worker，堆退出或外层溢出会作为显式失败报告。
+6. **dispose 至完全停稳**：服务自身的 dispose（资源释放）终止进行中的 worker 并*等待*其退出后再 resolve，遵循[防御性模式](../../../../docs/defensive-patterns.md)。
+
+### 信任姿态
+
+worker 运行时提供的是隔离，而非安全边界：模型代码可以访问 Node API，权限与 bash 工具相当。`worker.terminate()` 停止线程但不停止它 spawn 的 OS 进程。Code Mode 使用与 bash 相同的 `tools/pre-execute` 策略门禁，并额外提供空环境、堆限制、独立 isolate 和对程序本身的硬终止。需要硬多租户边界的部署需要为代码和 bash 都使用容器级后端；运行时的 isolation 描述符让它们能区分该后端。
+
+### 模型看到的内容
+
+SDK 指示模型编写一个异步的可擦除 TypeScript 函数体，通过 `await tools.name(args)` 调用工具，在需要时捕获被拒绝的工具调用，并仅 return 或 log 应重新进入上下文的输出。即使在 `Promise.all` 下调用仍保持顺序。声明前缀可能与原生 schema 一样大，尤其在 `'both'` 下，但对提供方缓存保持稳定。
+
+## 后果
+
+切换到 `'code'` 的部署必须更新任何仅限 native 的 `toolOrder`。组装监听器有责任维护任何被重写的协议面的完整性。子分发保持序列化，而每次调用的上下文会通过外层结果保留其 source、信封与元数据。
+
+## 测试
+
+- **Worker 运行时：** 真实 worker 测试覆盖类型化的绑定值与失败、每一种无损 JSON 根类型的完成值、无效和超限输出、精确的组合账本边界、compute 和 wall 预算、恶意绑定流量、空环境以及 dispose 至完全停稳。一个构建后包测试在纯 Node 下运行 worker 入口。
+- **注册表集成：** 测试覆盖代码生成、所有呈现模式、保留名称和限制规则、scoped 可见性、权威组装重写、`toolOrder`、运行时兼容性失败、完整流水线子分发、parent-token 关联、序列化、取消和队列排空、JSON 规范化、错误传播、日志事件、成功与失败程序中的有序上下文延后、外层阻止抑制以及 HMR（热模块替换）清理。
+- **带密钥 e2e：** 真实模型在一个程序中组合两次 bash 调用；另一个模型通过 Code Mode fs 分发发现嵌套的工作区指令。测试验证折叠的请求头、关联的分发事件、结果文件、延后上下文和模型行为。
+- **快照：** `code-mode-turn`、`both-mode-turn` 和 `code-mode-workspace-context` fixture（测试前置数据）固定 SDK 文本、请求头工具列表、分发事件、延后上下文和结果卡片。
+
+## 曾考虑的替代方案
+
+**一个零核心改动的附加消费方插件。** 否决，因为 `agent/request` 在[可重建请求](../architecture/2026-07-05-reconstructable-requests.md)下仅限 call-config，而变换已组装的工具列表需要在不拥有其配置的情况下撤销 `toolOrder` 规范化，并依赖监听器顺序。向模型提供哪些工具、以何种表示形式提供，是注册表的单一关注点：原生 schema 和 SDK 是同一个可见存储的两种投影。
+
+**`node:vm` 作为参考运行时，加固推迟。** 否决：`node:vm` 不是隔离（原型链逃逸可达宿主 realm）且无法中断热循环。worker 线程提供独立 isolate、空环境、`resourceLimits` 和可靠的 `terminate()`，信任等级等同于 bash，因此参考实现和生产实现是同一个包，无需 unsafe-acknowledgement 仪式。
+
+**在原生工具调用上做结果省略/摘要。** 仅解决问题的上下文膨胀一半：裁剪旧 `tool-result` 作为可重建请求下的日志化表面替换成本低，但仍需每次调用一次模型往返，且无法表达循环、分支或汇合。互补而非竞争；它可以在 Code Mode 下为残余的原生调用分层。
+
+**循环中的并行原生分发。** 往返成本的另一个答案；仍是有效的未来工作（open TODO），仍被并发安全元数据阻塞，且仍无组合能力——它并行化的是模型在一步中已经决定的调用。Code Mode 的序列化队列决策保持两者兼容：当元数据就绪时，原生并行分发和每工具绑定并行化一起解锁。
+
+**始终排他（忠于 Cloudflare，无模式）。** 否决，因为本 SDK 的主要消费方是编码 agent：其日常的单次调用（`bash`、`read`、`edit`）作为原生调用已经是最优的，强制每次编辑都通过程序会给常见场景增加负担。mode 配置让忠实形式（`'code'`）只需一行配置即可启用，而不强加于人。
+
+**每工具可见性分层（此工具 native，彼工具 code-only）。** 推迟：它需要每工具元数据和 `'native' | 'code' | 'both'` 不提供的呈现拆分，且其设计取决于模型在 `'both'` 下如何分配使用的证据。
+
+**SDK 中的清洁化标识符别名**（`my-tool` → `my_tool`，Cloudflare 的做法）。否决：`declare const` 上的带引号键使每个名称可达，零别名碰撞逻辑；模型能正常处理 `tools["my-tool"](…)`。
+
+**REPL 风格的持久内核**（状态跨 `run_code` 调用存活）。在 MVP 中否决：跨调用状态对会话日志不可见，破坏了「每个请求是日志的纯函数」这一可重建性保证；每次 run 全新保持了这一点。内核风格的后端在未来仍可通过同一 seam 表达，配合自己的日志方案。
+
+## 风险
+
+**Worker 不是硬安全边界。** 有意为之且已文档化（§信任姿态）：姿态等同于既有的 bash 工具，隔离程度超过它，门禁使用相同的 seam。需要更强隔离的部署需要未来的 `isolation: 'container'` 后端——作为 seam 设计的扩展点跟踪，而非本设计的 TODO。
+
+**`stripTypeScriptTypes` 标记为 experimental。** 它与 Node 自身原生 `.ts` 执行背后的引擎（amaro/swc）相同，在本仓库的整个引擎范围内作为 API 暴露。缓解措施：运行时的单元测试套件固定了所依赖的行为（位置保持、可擦除限制的拒绝消息形状宽松匹配），调用位于一个私有函数之后，且 `amaro`/`sucrase` 是 API 变化时的直接替代品。仅可擦除子集是面向模型的契约线，错误路径是一个可工作的反馈循环，而非死胡同。
+
+**SDK 的提示词成本，尤其在 `'both'` 下。** `.d.ts` 可能与它补充的原生 schema 体量相当；`'both'` 携带两种表示。前缀稳定性 + 提供方缓存摊销了每会话成本；mode 是每部署的；本 Agent Note 不做无条件节省的声明。何时优先使用哪种模式的量化指导明确属于上线后学习。
+
+**注册表 scope 增长。** `dsh-tools` 吸收了代码生成、一个工具、一个桥和一个事件。通过包内的模块边界（`ts-types.ts`、`code-mode.ts` 与 `schema.ts`/`json-schema.ts`/`presentation.ts` 并列）和 seam 约束：所有基底相关的内容都在 `ctx.codeRuntime` 之后。
+
+**大型无损 JSON 值可能耗尽内存。** 工具绑定会在分发前对无损 JSON 创建快照，并完整返回规范 JSON 解析值。运行时会校验 worker 端口两侧，但不对单次绑定设置字节数上限；结构化克隆成本以及进程或 worker 内存构成实际边界。只有包含日志、完成值和失败诊断的组合外层输出账本受字节数上限约束。
+
+**仅序列化的子分发。** `Promise.all` 尚未获得挂钟并行性，仅减少往返次数；模型可能过度期望。说明中已声明；解除此限制与原生并行分发 TODO 所需的并发安全元数据绑定。
+
+**预算计量读取事件循环，而非 flag。** 忙碌时间轮询（`eventLoopUtilization()`）比精确 CPU 计量更粗糙——预算到期最多延迟一个轮询间隔——且其正确性声明（「pending 的分发不能暂停它」）对恶意程序是承重的。两侧都有单元测试（带 pending 诱饵分发的热循环在 `computeMs` 处死亡；在慢绑定上空闲的程序存活到 `maxWallMs`），轮询间隔是内部常量而非配置——部署无法将其误调为绕过手段。

## Problem
[The filesystem capability-seam Agent Note](../architecture/2026-06-17-filesystem-capability-seam.md) defines the filesystem capability seam (`ctx.fs`), the package split (`dsh-fs`, `dsh-fs-local`, `dsh-tool-fs`, plus the `dsh-fs-policy` policy plugin), and the observed-file/stale-version policy for read-before-write/edit checks — which the [split-fs-seam](../simplification/2026-06-26-fsspec-style-fs-seam.md) and [event-gate](../architecture/2026-06-26-file-context-as-event-gate.md) Agent Notes moved off `ctx.fs` into the `dsh-fs-policy` plugin on the `fs/*` event gate. The remaining decision for the first filesystem tool delivery is the model-facing schema surface: what arguments the model sees for `read`, `write`, and `edit`.

+# Agent Note: 文件系统工具 schema——面向模型的读/写/编辑接口形状
+
+Status: implemented
+
+[English](2026-06-17-filesystem-tool-schemas.md) | 中文
+
+## 问题
+
+[文件系统能力 seam Agent Note](../architecture/2026-06-17-filesystem-capability-seam.md) 定义了文件系统能力 seam（`ctx.fs`）、包（package）拆分（`dsh-fs`、`dsh-fs-local`、`dsh-tool-fs`，加上 `dsh-fs-policy` 策略插件），以及针对 read-before-write/edit 检查的 observed-file/stale-version 策略——[拆分文件系统 seam](../simplification/2026-06-26-fsspec-style-fs-seam.md)和[事件门控插件](../architecture/2026-06-26-file-context-as-event-gate.md) Agent Note 后来将其从 `ctx.fs` 移至 `dsh-fs-policy` 插件的 `fs/*` 事件门上。首次文件系统工具交付剩余的决策是面向模型的 schema 接口：模型在 `read`、`write` 和 `edit` 中看到哪些参数。
+
+该 schema 应足够小，以便在 `dsh-tool-fs` 的首次实现中完成，但又足够稳定，使未来的本地/远程/沙箱文件系统后端不需要改动面向模型的接口。同时应避免从参考系统中照搬所有选项。Claude Code 和 OpenCode 暴露了类似的核心文件工具，但在命名风格和额外 flag 上有所不同；本 Agent Note 为原型选择最小的共有接口。
+
+## 决策
+
+`@deepseek-ai/dsh-tool-fs` 在首个文件系统工具套件中暴露以下三个面向模型的工具：
+
+| 工具 | 我们的 schema | Claude Code | OpenCode | 说明 | 原型包含 |
+|---|---|---|---|---|---|
+| `read` | `read(file_path, offset?, limit?)` | `Read(file_path, offset?, limit?, pages?)` | `read(filePath, offset?, limit?)` | 仅文件；`offset` 从 1 开始；首版不支持图片、PDF 或多模态内容。 | 是 |
+| `write` | `write(file_path, content)` | `Write(file_path, content)` | `write(content, filePath)` | 创建或覆盖 UTF-8 文本。在默认 fs-policy 下，更新现有文件前必须先观测；创建新文件则不需要。 | 是 |
+| `edit` | `edit(file_path, old_string, new_string, replace_all?)` | `Edit(file_path, old_string, new_string, replace_all?)` | `edit(filePath, oldString, newString, replaceAll?)` | 字面字符串替换；默认要求唯一匹配；在默认 fs-policy 下必须先观测（任意窗口读取均算作观测）。 | 是 |
+
+schema 使用 snake_case 字段名（`file_path`、`old_string`、`new_string`、`replace_all`），与 Claude Code 及现有 DeepSeek Harness 工具 schema 示例保持一致。消费方包将这些面向模型的名称转换为 `ctx.fs` 调用和 `fs/*` 事件分发。
+
+## 工具 schema
+
+### `read`
+
+`read` 检视一个 UTF-8 文本文件并返回带行号的内容。
+
+参数：
+
+- `file_path: string`——必填。要读取的路径，由 `ctx.fs` 解析。
+- `offset?: number`——可选。返回的第一行，从 1 开始。默认为第一行。
+- `limit?: number`——可选。返回的最大行数。默认值与上限是 `dsh-tool-fs` / `ctx.fs` 的实现细节。
+
+首次实现不涉及的内容：
+
+- 无 PDF `pages` 参数。
+- 无图片或多模态文件读取。
+- 不通过 `read` 列出目录；如有需要，目录列表将作为单独的后续工具。
+
+### `write`
+
+`write` 创建或完整替换一个 UTF-8 文本文件。
+
+参数：
+
+- `file_path: string`——必填。要写入的路径，由 `ctx.fs` 解析。
+- `content: string`——必填。要写入的完整 UTF-8 文本内容。
+
+在默认 fs-policy 下，使用 `write` 更新已有文件需要同一执行上下文先前对该文件有过一次观测（read/write/edit）；`dsh-fs-policy` 插件将观测到的版本作为 `fs/write-intent` 上的 stale guard 提供。创建新文件不需要先前观测。如果策略插件不存在，`write` 是无条件的裸提供方 create-or-overwrite。
+
+schema 不将 `expected_hash`、`expected_version` 或 `create_only` 作为面向模型的参数暴露。陈旧版本检查由后端产生的版本和策略插件的观测状态驱动，而非要求模型通过 schema 复制版本令牌。
+
+### `edit`
+
+`edit` 通过替换字面文本来更新已有的 UTF-8 文本文件。
+
+参数：
+
+- `file_path: string`——必填。要编辑的路径，由 `ctx.fs` 解析。
+- `old_string: string`——必填。要替换的字面文本。首次实现中空字符串无效。
+- `new_string: string`——必填。字面替换文本；空字符串表示删除匹配内容。
+- `replace_all?: boolean`——可选。默认为 false。为 false 时，`old_string` 必须恰好匹配一处。
+
+`edit` 要求同一执行上下文先前对该文件有过一次观测（任何窗口化的 read 都算——授权基于版本新鲜度，而非全文查看要求），或该上下文先前对该文件做过 write/edit。`dsh-fs-policy` 策略插件推导所有者并将记录的版本作为 stale guard 提供；提供方的 mutation lock 负责执行。
+
+首次实现拒绝 Codex 风格的 patch 语法和多模式 edit API。它使用一种严格的字面替换模式，使面向模型的契约保持简单，并让后端掌控精确匹配、重复匹配、行尾和陈旧版本的语义。
+
+## 结果形状
+
+首次实现曾将 `ContentBlock[]` 格式化逻辑放在 `execute` 中。[规范工具输出契约](../architecture/2026-07-20-canonical-tool-output-contract.md)如今将 `ctx.fs` 的结果事实保留为工具经校验的值，并通过 `output.render` 派生相同的模型文本；文件状态的记录/刷新仍归 `ctx.fs` 所有。
+
+默认原生投影：
+
+| 工具 | `tool-fs` 使用的结构化 `ctx.fs` 结果 | 默认模型投影 |
+|---|---|---|
+| `read` | 返回的行、返回行数、总行数、目标显示路径、文件版本、部分视图标记 | 带行号的文本及分页页脚 |
+| `write` | 创建/更新操作、目标显示路径、新文件版本 | 简洁的创建/更新成功文本 |
+| `edit` | 替换次数、全量替换标记、目标显示路径、新文件版本 | 简洁的编辑成功文本 |
+
+结构化结果不会重复模型参数（如 `file_path`、`old_string` 或 `content`），除非后端已将其解析为新信息（如 `displayPath`、`targetKey` 或新版本）。面向 token 的截断属于模型投影的职责，而非后端规范结果的一部分。
+
+## 延后事项
+
+以下内容被明确排除在首次文件系统 schema 实现之外：
+
+- 面向模型的 `expected_hash`、`expected_version` 或 `create_only` 参数。
+- 目录列表、glob、grep 和搜索工具。
+- 二进制安全的读/写操作。
+- PDF/图片/多模态 `read`。
+- 文件系统工具的 Code Mode 投影值。
+- 规范的 edit diff 格式。
+
+## 测试
+
+schema 测试固定每个工具的必填/可选参数集、空 `old_string` 拒绝、`replace_all` 默认值、snake_case 字段名、描述文字中对观测策略的说明，以及根插件套件注册；集成测试通过 `ctx.tools.execute()` 对真实的 `dsh-fs-local` 提供方执行全部三个工具，并验证模型参数被正确转换为预期的 `ctx.fs` 调用和 `fs/*` 分发。
+
+## 曾考虑的替代方案
+
+- **Codex 风格的 patch 语法或多模式 edit API**：否决。一种严格的字面替换模式使面向模型的契约保持简单，并让后端掌控精确匹配、重复匹配、行尾和陈旧版本的语义。
+- **camelCase 参数名（OpenCode 风格）**：snake_case 与 Claude Code 及现有 harness 工具 schema 示例一致，且命名一旦发布即成为公开接口。
+- **面向模型的 `expected_hash` / `expected_version` / `create_only` 参数**：否决。陈旧检查由后端产生的版本和策略插件的观测状态驱动，从不依赖模型复制的脆弱令牌。
+
+## 后果
+
+**首版 schema 有意小于 Claude Code 的。** 去掉 PDF pages、多模态 read、丰富的 grep/list flag 和 expected hash 字段使实现保持聚焦，但用户可能很快就会提出这些需求。它们将以独立 Agent Note 或聚焦的后续工作形式到来，而非对初始 schema 的重载。
+
+**v1 中没有显式的面向模型的 stale guard。** schema 不要求模型提供 expected hash/version。这是有意为之：陈旧检查来自后端产生的版本和 `dsh-fs-policy` 插件的观测状态，而非模型复制的脆弱令牌。文件系统安全失败通过 `dsh-fs` 拥有的结构化 `FsError` 代码浮现，而非模型提供的版本字段。
+
+**命名成为公开接口。** 一旦发布，将 `file_path` 改为 `filePath` 或 `old_string` 改为 `oldString` 会搅动提示词、示例和下游客户端。本 Agent Note 预先选择 snake_case，并将其视为稳定的面向模型的契约。

-# Agent Note: Rich ACP bash rendering — the terminal card via the `_meta` convention
-
-Status: implemented
-
-## Problem
-
-The ACP bridge lets each tool own its call rendering via `presentCall`/`presentResult` (see [tool-call UI presentation](2026-06-14-acp-agent-client-protocol.md) and `packages/core/tools`). For `bash` we surface the exact command as the `tool_call` title, the model's `description` as a content text block, `kind: 'execute'`, and the completed output wrapped in a fenced ` ```console ` text block.
-
-Reference editors render terminal metadata as a dedicated card with cwd, command, live-style output, and exit status; plain text loses that structure. The command is the title because execute cards hide raw input, while the human-readable description remains a separate block above the card.
-
-## Key finding: agent-executed terminals use a `_meta` convention, NOT `terminal/create`
-
-The ACP spec has a *client-side* terminal sub-protocol — the agent calls the client's `terminal/create` with `{ command, args, cwd, env }` and the **editor** executes the process, then the agent reads `terminal/output` / `wait_for_exit`. That model is wrong for us: our harness executes bash itself through `dsh-bash` (sandboxed env-scrub, background-task ownership, per-session cwd). Routing execution to the editor would bypass all of that and fork execution into two backends.
-
-Studying the two reference agents (2026-06-18) shows neither uses `terminal/create` for their own shell tool — **both keep agent-side execution and emit a `_meta` convention** that Zed special-cases:
-
-- **`claude-agent-acp`** (`tools.ts`, `acp-agent.ts`): gated on `clientCapabilities._meta.terminal_output`. The `tool_call` carries `content: [{ type: 'terminal', terminalId }]` and `_meta.terminal_info.{ terminal_id, cwd }`; output/exit arrive on the `tool_call_update`'s `_meta.terminal_output.{ terminal_id, data }` and `_meta.terminal_exit.{ terminal_id, exit_code, signal }`.
-- **`codex-acp`** (`CodexToolCallMapper.ts`, `TerminalOutputMode.ts`): same `terminal_info` on the call; output via `_meta.terminal_output` (full) or `_meta.terminal_output_delta` (incremental), selected from the same `_meta.terminal_output` capability.
-
-Zed's side (`crates/agent_servers/src/acp.rs`, verified): on a `ToolCall` whose `_meta.terminal_info.terminal_id` is set, it registers a **display-only** terminal (header = `terminal_info.cwd`, label = `tool_call.title`); on a `ToolCallUpdate`, `_meta.terminal_output.data` writes to that terminal and `_meta.terminal_exit.{exit_code,signal}` sets the status. It advertises the capability as `clientCapabilities._meta.terminal_output = true`. `_meta` itself is a spec-blessed ACP extensibility point (typed `{[k]: unknown} | null` on `ToolCall`/`ToolCallUpdate`); the *specific keys* here (`terminal_info`/`terminal_output`/`terminal_exit`) are a Zed convention, not part of the ACP spec — but they are the de-facto contract for the Zed integration and the only way to get the terminal card while keeping execution agent-side.
-
-## Decision
-
-Keep `dsh-bash` agent-side execution; render the terminal card via the `_meta` convention, capability-gated, with the ` ```console ` text block as the guaranteed fallback.
-
-1. **Capability.** `initialize` reads `clientCapabilities._meta.terminal_output` and the bridge remembers it per connection.
-2. **Neutral presentation vocabulary.** `dsh-tools` gains a terminal-shaped presentation a tool can return — provider-neutral (`cwd`, the output `data`, an `exitCode`/`signal`), NO ACP types. `dsh-tool-bash` returns it for `bash` (cwd from the resolved workdir; output + exit parsed from the run result).
-3. **Bridge mapping.** When the client advertised the capability, the bridge maps that presentation to: on `tool_call`, `content:[…, {type:'terminal', terminalId}]` (any tool `content`, e.g. the description, rendered BEFORE the terminal block) + `_meta.terminal_info.{terminal_id,cwd}`; on `tool_call_update`, `_meta.terminal_output.{terminal_id,data}` (the captured output) + `_meta.terminal_exit.{terminal_id, exit_code|signal}` (the parsed exit), with the update's text `content` OMITTED (an ACP `tool_call_update.content` REPLACES the call's content collection, so re-sending the fenced block would clobber the terminal content block). `terminalId` is derived from the harness `callId` (stable, unique per call). When the capability is absent, the bridge sends the description content block on the call and the existing ` ```console ` text content on the update — unchanged.
-4. **The exit pill is parsed from the rendered output; no new execution path, no live streaming.** Output is attached at completion (from the agent's own `tool/result`), not streamed token-by-token. The exit-status pill (`_meta.terminal_exit.{exit_code,signal}`) IS emitted: the pure `presentResult(args, result)` seam sees only content blocks, so `dsh-tool-bash` recovers the structured exit by parsing the status markers (`[exit code: N]` / `[killed by signal: …]`) that `renderResult` appended — the parse is the exact inverse of the marker emission, the two co-evolve in one file, and a round-trip test guards the pair. Disposal is unaffected: nothing new to tear down, since the bridge never creates a client-side terminal.
-
-## Alternatives considered
-
-- **The ACP client-side terminal sub-protocol (`terminal/create`)** — explicitly rejected: the editor would execute the process, bypassing `dsh-bash`'s env scrub, background-task ownership, and per-session cwd, and forking execution into two backends. Both reference agents reject it the same way (the key finding above); agent-side execution plus the `_meta` convention is the only shape that yields the terminal card while keeping the harness's execution policy.
-- **Threading a structured exit through the event schema** — rejected in favor of the marker round-trip: the pure `presentResult(args, result)` seam sees only content blocks, and the parse is the exact inverse of the marker emission, co-evolving in one file under a round-trip test.
-
-## Consequences
-
-- **Zed-convention `_meta` keys.** The terminal card rides on Zed-specific keys (`terminal_info`/`terminal_output`/`terminal_exit`) inside ACP's spec-blessed `_meta` extensibility point, NOT on the ACP terminal sub-protocol. A client that doesn't recognize the keys still gets the text fallback (the capability gate ensures we only emit them when the client opted in via `_meta.terminal_output`), so a non-Zed client is never worse off. If ACP later standardizes agent-executed terminals, migrate to that and drop the convention keys.
-- **Capability honesty.** Emit terminal metadata ONLY when the client advertised `_meta.terminal_output`; the text fallback is the contract for everyone else and must never regress. Covered by a no-capability test asserting the ` ```console ` path.
-- **terminalId collisions.** Deriving it from the per-call `callId` keeps it unique within a session and stable across the call/result pair; never reuse one across calls.
-- **Exit parsed from rendered text.** The exit pill recovers `exit_code`/`signal` by parsing `renderResult`'s status markers rather than threading a structured exit through the event schema (which the pure `presentResult` seam never sees). The parse is the exact inverse of the marker emission and lives in the same file; a round-trip test pins the pair so a marker-format change that breaks the parse fails the suite. If the markers ever need to diverge from what the pill wants, surface a structured exit on the result event instead.
-- **Provider-neutral vocabulary creep.** The terminal presentation widens the `dsh-tools` surface; keep it neutral (no ACP types leak into `dsh-tools`) and only as rich as a second UI consumer would also want.
-
-## Out of scope / non-goals
-
-The text-block baseline stays the no-capability default. Two follow-ups are deliberately NOT built here and would each warrant their own Agent Note when someone takes them on: **live incremental streaming** (`_meta.terminal_output_delta` as chunks arrive, which needs an incremental-output seam on `dsh-bash`), and **command classification** (parsing a `cat`/`sed` as a `read` card with a file location, a `grep` as a `search`, etc., falling back to the terminal card — display-only, must never change what executes).

## Problem
A long-running agent conversation grows without bound. As the event log accumulates turns, the derived message history eventually approaches the model's context window — the model then truncates mid-response (`max-tokens`) or degrades. **Compaction** is the mitigation: replace a run of older history with a concise summary, keeping recent context intact.

+# Agent Note: 压缩作为能力 seam（抽象契约 + 基础后端）
+
+Status: implemented
+
+[English](2026-06-18-compaction-capability-seam.md) | 中文
+
+## 问题
+
+长时间运行的 agent（智能体）对话会无限增长。随着事件日志不断累积轮次，派生出的消息历史最终逼近模型的上下文窗口，模型随即截断响应（`max-tokens`）或性能退化。**上下文压缩（context compaction）** 是对此的缓解手段：用一段简洁的摘要替换一批较早的历史，保持近期上下文完整。
+
+[会话接口面](../architecture/2026-06-18-session-surface.md)正是为此而构建的基础设施：一份建立在事件日志之上的有序投影，带有专门设计的 `surfaceOp: { op: 'replace', start, end }` 操作，用于遮蔽一段条目并插入替换内容，`sourceEventSeqs` 记录溯源信息以便决策可确定性地回放。剩下的是那个*决定压缩什么、并产出摘要*的插件。
+
+两股力量塑造了设计。第一，压缩策略与可复用的 token 测量独立变化：测量归 LLM 系列的 [`ctx.tokenMeter` 服务](../architecture/2026-07-15-replay-token-meter-service.md)所有，摘要生成则可以使用模型调用、模板或远程服务。第二，`SurfaceEventType` 封闭为五种事件类型（`user/message`、`assistant/message`、`tool/result`、`context/message`、`steering/message`）；只有这些类型可以携带 `surfaceOp`。因此一个专用的 `compaction/*` 事件**不能**出现在 surface 上，编译器与 Session 始终启用的 append/seed 边界都会拒绝在其上附加 `surfaceOp`。
+
+## 决策
+
+### 压缩是一个能力 seam，接口与实现分离
+
+遵循[能力 seam Agent Note（agent 决策记录）](../architecture/2026-06-13-capability-seams.md)，压缩以独立包（package）发布，使契约、算法和（后续的）消费方 surface 各自独立演进：
+
+1. **接口** — `@deepseek-ai/dsh-compact`：抽象 `CompactService`，拥有 `ctx.compact` 键、`CompactionResult` 词汇、`compact/*` 会话事件以及规范的检查点消息来源。它将 `compactIfNeeded()` 和 `compactRegion()` 声明为**抽象方法**——契约说明压缩*做什么*，而非*怎么做*。
+2. **实现** — `@deepseek-ai/dsh-compact-basic`：具体的 `BasicCompactService`，消费 `ctx.tokenMeter`，并拥有尾→头保留遍历、通过 `ctx.llm.stream()` 生成摘要、surface 替换、锁、步骤后压力处理和规范的上下文溢出恢复。`summarize()` 是其唯一的子类钩子；计价与回放仍归 meter 所有。
+3. **无模型配套服务** — `@deepseek-ai/dsh-compact-tool-result-prune`：一个具体的可选服务，在后端选择摘要范围之前，重写当前过大的 `tool/result` 节点。它不是第二种压缩实现，也不实现 `CompactService`。
+4. **消费方** — 推迟。一个 `/compact` 工具和斜杠命令将 `inject: ['compact']` 并调用契约；它们被有意排除在本 Agent Note 范围之外，以便 seam 先稳定下来。
+
+### 契约依赖 `dsh-session` 和 `dsh-llm`——有意为之的偏离
+
+能力 seam Agent Note 规定接口包「仅依赖 cordis」（对 `dsh-bash` 成立，因为其词汇是自包含的）。压缩**无法**遵守这一点：它的动词作用于 agent 所有的 `Session`（`compactRegion(start, end, agent)`），其输出使用内容词汇（`CompactionResult.summary: ContentBlock[]`）。不引用 `Session`/`SessionEvent`（来自 `dsh-session`）和 `ContentBlock`（来自 `dsh-llm`），契约就无法表达。
+
+这不是耦合异味，而是契约的领域所在。「仅 cordis」的指导原则一直是「接口仅依赖契约真正需要命名的东西，绝不依赖实现」的简写。`dsh-session` 和 `dsh-llm` 本身是接口/词汇包，不是实现；`dsh-compact` 仍然不导入任何后端。seam 的真正不变式——*消费方和实现在抽象服务背后独立演进*——完好无损。
+
+### 抽象 `compactIfNeeded` / `compactRegion`，算法在后端
+
+早期草案将完整算法（保留遍历、token 求和、文本提取）作为接口上的具体方法。这会将契约重新耦合到一种策略：想要不同保留策略或事件排序的后端必须与继承来的具体代码对抗。将两个核心方法都设为抽象，把所有*怎么做*的决策放在后端，并让接口保持为*做什么*的声明。token 测量根本不是压缩钩子；单例服务使多个消费方能够共享逐会话的回放折叠。
+
+`compactIfNeeded(agent, trigger, signal)` 接受显式的 `'pressure' | 'context-overflow'` 触发原因与取消信号。它只读取最新的持久化已路由请求；没有 header 就不执行工作，任何已路由的提供方/模型目标都使用单例估算器。`compactRegion(start, end, agent, signal?)` 将 `agent.session` 作为唯一会话身份，并为手动调用方保留可选 signal。默认摘要器依次从显式配置、最新记录的已路由目标和 agent 选项解析目标，并在任何 `llm/stream` 路由后记录提供方/模型对。它回放已路由请求的前缀，并将压缩指令追加为尾部 user 消息，从而复用提供方的热 KV cache；见[摘要前缀缓存 Agent Note](../bug-fix/2026-07-21-compaction-summary-prefix-cache-reuse.md)。该调用将提供方无关的 `GenerateOptions.purpose` 设为 `compaction`；适配器可以将此用途映射为对模型隐藏的传输元数据，DeepSeek 适配器会发送 `x-deepseek-harness-compact: 1`。
+
+### 成功的持久步骤工作完成后运行自动压力检查
+
+成功调用的压力检查不能在步骤前运行，因为最终的 `agent/request` 路由、提供方输出、工具结果、缓冲上下文与 steering 当时尚不存在。串行的 `agent/post-step(agent, turn, step, signal)` 会在这些事实持久化后、`step/end` 之前触发。`dsh-compact-basic` 通过 `ctx.tokenMeter` 测量规范的已记录请求，因此下一个请求无需推测性覆盖信封即可看到任何替换。压力达到条件后，可选的 `ctx.toolResultPrune` 重写在摘要范围选择前运行；compact-basic 重新测量持久 surface，如果修剪恢复到安全压力便跳过摘要生成。
+
+规范的提供方上下文溢出走另一条路径。失败步骤先关闭，`agent/request-error` 接收原始请求错误与连续重试次数，compact-basic 在强制执行一次有效且平衡的缩减前先修剪。仅当 `session.surface.replaceGeneration` 增加时，它才返回 retry；这包括没有摘要范围时仅修剪取得的进展。随后循环开启新的编号步骤，并从持久日志重建请求。没有替换、任何替换前的恢复失败、取消、耗尽的上限或无关错误都会保留原始提供方失败。如果修剪已经推进 generation，而后续摘要工作失败，恢复会从该持久的已修剪 surface 重试，除非取消或资源释放胜出。完整生命周期决策见[调用后恢复 Agent Note](../architecture/2026-07-10-after-call-compaction-pressure-and-overflow-recovery.md)。
+
+```
+assistant/message → tool/result/context/steering
+await serial agent/post-step ⟵ pressure compaction inside the successful step
+step/end
+
+provider overflow → step/end
+await waterfall agent/request-error ⟵ forced compaction between attempts
+retry → next numbered step/start ⟵ derives from the replacement surface
+```
+
+### 保留是轮次无关的；工具配对平衡是唯一的结构守卫
+
+自动压缩在**每个成功的**步骤之后检查，而非每轮一次。这对失控轮次存活至关重要：工具密集型的 ReAct 轮次每步追加一个 `assistant/message` + 一个 `tool/result`，因此 surface 会在一轮之内增长。步骤后检查可以在后续步骤开启前压缩早期已关闭的工具对；如果请求率先越过限制，由提供方确认的溢出仍是兜底机制。
+
+`compactIfNeeded` 保留估算大小达到解析后保留 token 预算的最小完整 surface 单元尾部，压缩更早的节点。一个单元是一个完整的已关闭步骤或一条无步骤消息。如果 token 截断点落在步骤内部，保留范围会扩展直到切割点满足工具配对平衡。平衡按 surface 顺序检查，而非日志序号，因为替换摘要在旧的 surface 位置拥有新的序号。`dsh-compact` 导出前后边缘辅助函数；只要 `replaceGeneration` 不变，其逐会话缓存就只折叠新增的 surface 尾部节点，面对仅日志增长时不读取事件，并在替换后重建当前成员关系与平衡。`compactRegion` 拒绝将工具调用与其结果拆分的边界。进行中的轮次不享受特殊保留。
+
+因此失控轮次的压缩方式与其他历史完全相同：其早期*已关闭*步骤被摘要，近期步骤保持原样。当唯一可压缩的内容只剩一个不可拆分的开放尾部步骤（其工具调用尚无结果）时，压缩拒绝执行（返回 `null`）并在该步骤关闭后重试。
+
+**部分单单元溢出仍不在范围内。** 摘要范围选择无法拆分不可分割的单元。当可移除的文本型工具结果内容占据大部分空间，且修剪后的余量能够容纳时，可选修剪器可以修复一个已关闭的工具对。仅信封压力、粘贴的 `user/message` 等不可分割的超大非工具节点，以及不可修剪余量仍然过大的工具单元，依旧不属于压缩范围；限制这些单元是另一个关注点。
+
+### 头部锚定：一个自动检查点，始终在头部
+
+自动压缩始终从 surface 头部开始，将先前的检查点与新压缩的历史合并，因此只保留一个自动检查点。`shadowedRange` 因此是位置性的而非数值序号区间：一个较新的摘要序号可能占据较旧的 surface 位置。`shadowedSeqs` 记录权威的 surface 顺序。手动的中间范围压缩可能留下多个检查点。
+
+### 近似收敛不变式
+
+`resolveConfig` 提供可用默认值：阈值比例 `0.8`、保留尾部比例 `0.16`、空的摘要提供方/模型覆盖、`maxTokens: 8192`、`compactionRetries: 1`、`maxOverflowRetries: 1` 以及 `auto: true`。可选的精确提供方/模型策略会部分覆盖顶层默认值；压力根据拥有该路由的 LLM 适配器所报告容量缩放比例，而 `retainTokens` 可以替代按比例保留。保留量必须低于最终阈值。收敛仍然是动态的，因为提供方输出上限可能被隐藏或显式的推理 token 消耗，摘要大小也不可预测。如果压力仍高于阈值，`compactIfNeeded()` 会按配置的重试次数再次压缩头部检查点，但每次提交的摘要必须小于其遮蔽的内容。溢出不需要容量元数据，并会绕过阈值和保留尾部策略，执行一次最大且平衡的头部缩减，留下最新的不可分割单元。所有权划分由[已路由模型上下文与压缩策略 Agent Note](../architecture/2026-07-20-routed-model-context-and-compaction-policy.md)规定。
+
+### Surface 替换：`compact/*` 事件仅存在于日志；一条 `user/message` 承载摘要
+
+由于 `SurfaceEventType` 是封闭的，摘要不能搭载在 `compact/*` 事件上。后端改为追加一条**单独的 `user/message`**，带有 `source: COMPACT_CHECKPOINT_SOURCE` 和 `surfaceOp: { op: 'replace', start, end }`；其 `content` 是（带框架的）摘要，`sourceEventSeqs` 覆盖被遮蔽的条目*和*簿记事件。接口导出该来源和 `isCompactCheckpointSource()`，使消费方无需依赖后端包身份，即可识别持久化或克隆得到的检查点。`compact/*` 事件是纯日志记录（锁 + 溯源信息）。surface 变更位于锁**内部**，`compact/end` 是最后追加的事件：
+
+```
+compact/start → log-only. Acquires the lock.
+[summarize older range via the backend]
+compact/summary → log-only. Provenance: raw summary, range, shadowed seqs, token count.
+user/message → canonical checkpoint source + surfaceOp { op:'replace', start, end }.
+ THE surface mutation (framed summary).
+ deriveMessages() renders it as a user-role message.
+compact/end → log-only. Releases the lock (carries `error` on a recoverable failure).
+```
+
+`deriveMessages()` 随后产出 `[summary_as_user_message, ...retained_entries]`。复用 `user/message` 是诚实的而非变通：摘要确实*是* user 角色的上下文。
+
+### 检查点框架 + 增量合并（后端私有）
+
+基础后端将摘要包装为已建立的检查点上下文，并标记以便下一轮增量合并。原始摘要保留在 `compact/summary` 上。框架是后端策略；seam 承诺由一条替换 user 消息承载可能带框架的摘要，并使用规范的检查点来源。
+
+### 通过日志记录的锁实现阻塞，加上崩溃/可恢复失败的分类
+
+`compact/start … compact/end` 括号的存在理由，按当前实际承担的职责排序：
+
+1. **可检测的崩溃孤儿 + 来源追溯**（首要）。摘要生成是一次慢速模型调用，持久化在 `compact/start` *之后*。摘要生成中途崩溃会留下一个没有匹配 `compact/end` 的 `compact/start`——一个可检测的孤儿。最后释放锁（而非最先）将崩溃窗口从*静默损坏*转变为可检测的孤儿。
+2. **防止并发压缩。** 如果当前轮次持有未匹配的 `compact/start`，`compactRegion` 拒绝启动。（循环在任一 awaited 自动 seam 上都是单线程的，因此这也是重入绊线——抛出「already in progress」表示真正的 bug。）
+
+该锁只排除另一项压缩，不排除无关的仅日志事实。基础后端会在 `compact/start` 之后对 token meter 的 surface 节点取快照，并在异步摘要后再次比较；任何 surface 变更都会使替换前的检查失败，而标题或其他仅日志追加不会使已选范围失效。
+
+两种失败路径，均有文档记录：
+
+- **崩溃**（循环在摘要生成中途死亡）：悬空的 `compact/start`，无关闭事件。由于 `compact/*` 是**仅日志**事件，孤儿是**惰性的**，不会落地摘要替换。派生 surface 保持为 `compact/start` 时已经持久化的 surface：如果修剪未产生替换，就是完整历史；如果已经修剪，就是已修剪历史。通用轮次修复（`interruptedTurnClosers`）用合成的 `turn/end` 关闭轮次；孤儿位于该 `turn/end` *之前*，因此轮次范围内的进行中检查永远看不到它，崩溃不会卡住未来的压缩。
+- **可恢复**（摘要生成抛出异常但循环存活）：后端追加设置了 **`error`** 字段的 `compact/end`，但不落地摘要替换。步骤后压力处理发出警告，并从最新的持久 surface 继续：如果尝试前没有替换，就是完整历史；如果修剪已经落地，就是已修剪 surface。溢出恢复只会在没有任何替换前委托；先前修剪带来的 generation 进展允许从该持久 surface 重试，除非取消或资源释放胜出。
+
+`compact/end` 保留其 `error?` 字段（与 `tool/result` 的自包含错误一致——一个事件即可区分成功与失败，无需关联兄弟事件）。没有单独的 `compact/error` 事件。
+
+**核心会话修复保持对压缩无感知——这是有意为之。** `interruptedTurnClosers` 从不被教导 `compact/*`。如果教导它，每个未来的 `xxx/start … xxx/end` 插件对都必须修补核心模块——这恰好是能力 seam 架构存在的意义所要避免的耦合。由于仅日志的孤儿是惰性的，不需要特殊修复：通用轮次修复加上未落地 surface 变更的惰性就足够了。
+
+## 曾考虑的替代方案
+
+- **完整算法作为接口的具体方法**——否决，因为它将契约重新耦合到一种保留策略。两个核心方法都是抽象的；可复用测量属于单独的 LLM 系列服务，`summarize()` 是 basic 唯一的钩子。
+- **在 `agent/request` 或临时 `agent/pre-step` 输入上执行压缩**——否决，因为两者都无法证明最终的持久请求，而且都会将通用生命周期耦合到压缩专属的信封数据。步骤后回放与规范溢出恢复同时覆盖成功和被拒绝的调用。
+- **`compact` 布尔值或无类型的请求元数据 map**——否决，因为多个辅助调用种类会变成互斥标志，而开放 map 会丢弃由编译器检查的词汇。一个类型化的 `purpose` 判别字段可以扩展其他调用种类，而无需再为 `GenerateOptions` 添加字段。
+- **单独的 `compact/error` 事件**——否决：`compact/end` 保留 `error?` 字段，与 `tool/result` 的自包含错误一致——一个事件即可区分成功与失败，无需关联兄弟事件。
+- **教导核心轮次修复识别 `compact/*`**——否决：仅日志的孤儿是惰性的，为每个未来的 `xxx/start … xxx/end` 插件对修补核心模块恰好是能力 seam 架构存在的意义所要避免的耦合。
+
+## 后果
+
+- **包**：`packages/compact/compact` 提供接口，`compact-basic` 提供后端，`compact-tool-result-prune` 提供可选的确定性重写。`packages/llm/token-meter` 独立拥有回放感知的测量。消费方层推迟。
+- **自动 seam**：`agent/post-step`（`@mode serial`）处理成功调用的压力，`agent/request-error`（`@mode waterfall`）处理失败步骤关闭后的最终请求失败。通用 `agent/pre-step` 保持为四参数检查点，不携带压缩专属的提示词/前缀 payload。
+- **`SessionEventMap`** 通过可合并扩展的声明合并获得 `compact/start` / `compact/summary` / `compact/end`；`SurfaceEventType` **未被**触及。这些是会话事件，不是 cordis `Events`，因此事件分类门禁无需新增条目。
+- **`dsh-compact`** 拥有 `COMPACT_CHECKPOINT_SOURCE`、`isCompactCheckpointSource(source)`、`toolPairingBalancedBefore(session, seq)` 与 `toolPairingBalancedAfter(session, seq)`。该标记用于跨后端实现识别替换摘要。带缓存的 surface 边缘检查会防止 `compactRegion` 和 `compactIfNeeded` 拆分工具调用/结果对，按 seq 校验当前成员关系，从每个切割点的一条平衡序列回答两侧边缘，并拒绝陈旧或缺失的 seq 与孤立结果。
+- **`dsh-session`** 通过唯一的 surface 管理器校验位置替换、完整溯源信息和仅内容的单节点 `tool/result` 重写。其不变式配套插件将新追加的工具结果视为执行，要求存在已打开的步骤与待处理调用；已校验的替换仍是位于轮次内的重写。
+- **接线**：`examples/tui-agent/cordis.yml` 依次加载零配置的 `dsh-token-meter`、`dsh-compact-tool-result-prune` 和 `dsh-compact-basic`；服务级默认值使组合无需重复数值策略即可使用。
+
+## 测试
+
+- **单元测试：** 使用真实 Loader 和 invariant 插件覆盖完整单元保留、修剪配置与回放、富块顺序、元数据保留、收敛、`compact/end` 的两种结果、开放尾部拒绝、仅修剪与带摘要的溢出恢复、generation 证明、上限和原始错误保留。
+- **循环测试：** 测试固定步骤后处理发生在持久工具结果之后、`step/end` 之前，使用实际 `agent/request` 路由，关闭失败步骤，分配新的重试编号，并覆盖完整的抛出/带内溢出 → 压缩 → 重建重试组合。
+- **带密钥 e2e：** 真实模型和 bash 会话在降低的限制下触发压缩，记录完整的 `compact/start…end` 对，缩小 surface，并完成任务。
+- **快照缺口：** 失控轮次压缩尚无法回放，因为摘要调用未记录 `assistant/chunk` 事件或 `sessionId`；交错摘要调用的回放仍是后续工作。

+# Agent Note: Subagent 能力 seam
+
+Status: implemented
+
+[English](2026-06-21-subagent-capability-seam.md) | 中文
+
+> 完整 seam 已交付：`dsh-subagent` 接口与 `dsh-tool-subagent` 消费方；两个进程内后端（`dsh-subagent-spawn`、`dsh-subagent-fork`）；嵌套 agent 快照基础设施（[逐会话快照回放](../testing/2026-06-22-subagent-snapshot-replay.md)）；以及进程外后端 `dsh-subagent-acp`（[其 Agent Note](2026-06-22-acp-subagent-backend.md)）。
+
+## 问题
+
+harness 有一个长期搁置的 seam 用于 **subagent**：一个 agent（智能体）将工作委派给另一个 agent。这一意图在 `Agent`/`AgentLoop` 接口中已有草案（[packages/core/agent/src/types.ts](../../../../packages/core/agent/src/types.ts)、[packages/core/agent-loop/src/index.ts](../../../../packages/core/agent-loop/src/index.ts)）：一个创建选项引用父 agent（fork = 用父会话的事件日志初始化子会话；spawn = 全新会话），子 agent 以 `Agent` 句柄返回，使 steering（中途引导）和事件订阅可以统一工作。本 Agent Note 实现了这个 seam；上方横幅列出了已交付的内容。
+
+决定整体设计走向的核心需求是：**多种 subagent 实现必须在运行时共存**。一个父 agent 可能在同一个会话中既需要一个廉价的进程内子 agent 处理有限范围的子任务，又需要一个隔离的进程外子 agent（通过 ACP（Agent Client Protocol））。我们预见的传输方式：
+
+- **进程内**：在同一个 `Context` 上创建一个具体的子 `Agent`（最廉价，且鉴于现有 agent 工厂几乎零成本）；

+- 后续：**A2A**、**Codex app-server** 与 **Claude Code Agent SDK**——每种都与 ACP 后端相同的进程外形状：「启动子 agent、发送提示词、流式接收更新、取消」。
+
+## 曾考虑的替代方案
+
+### 为何不采用 bash seam 的形状
+
+bash seam（[能力 seam](../architecture/2026-06-13-capability-seams.md)）在每个上下文中只注册恰好一个 `BashExecutor`；加载第二个会抛异常。这对 bash 是正确的（一台机器、一种执行命令的方式），但对这里是错误的：共存才是需求。因此 subagent 服务是一个**命名提供方注册表**——每个实现以唯一名称注册，调用方按名称选择——镜像 **LLM（大语言模型）适配器注册表**（`LlmService.registerAdapter`），而非单服务的 bash 执行器。seam 仍然是由三个包构成的结构（接口 / 实现 / 消费方）；只是「一个 vs. 多个实现」这个维度不同。
+
+## 决策
+
+### 由三个包构成的 seam
+
+新建包（package）组 `packages/subagent/`：
+
+| 包 | 角色 |
+|---|---|
+| `@deepseek-ai/dsh-subagent` | 接口：`SubagentService`（`ctx.subagents`）、`SubagentProvider`、`SubagentRun`、请求/结果/能力词汇、`subagent/*` 事件 |
+| `@deepseek-ai/dsh-subagent-spawn` | 实现：通过 `ctx.agents.create` 创建全新的进程内子 agent |
+| `@deepseek-ai/dsh-subagent-fork` | 实现：用父 agent 日志快照初始化的进程内子 agent |
+| `@deepseek-ai/dsh-subagent-acp` | 实现：作为 ACP 客户端驱动已配置的子进程 |
+| `@deepseek-ai/dsh-tool-subagent` | 消费方：基于 `ctx.subagents` 的面向模型的 `subagent` 工具 |
+
+### 原语：异步 `start → SubagentRun`
+
+提供方暴露 `start(request) → Promise<SubagentRun>`。完成时发布一个就绪的子 agent 并将其运行句柄转交给调用方。一个信号覆盖就绪前后的取消；`dispose()`（资源释放）取消剩余工作并等待完全停稳。启动失败时清理部分资源，不发出生命周期事件。`start` 与传输方式无关；`spawn` 仅指代全新的进程内后端。
+
+### 两类可选能力，两种发现方式
+
+- **启动时功能**（`outputSchema`、`depthLimit`、`toolFilter`、`persona`）挂在静态的 `provider.capabilities` 描述符上。服务在委派之前检查每个被请求的功能，如果提供方不支持则**大声拒绝**（`SubagentError('UNSUPPORTED_CAPABILITY')`），绝不接受后静默忽略。这些功能必须在 run 存在之前检查，因此不能是运行时方法。
+- **运行时功能**（通过 `sendMessage` 进行 steering、通过 `resume` 进行后续对话）是 `SubagentRun` 上的**可选方法**。方法的存在本身即为能力，TypeScript 类型收窄即为发现机制：消费方不经收窄就无法调用不存在的方法，因此不存在静默降级路径，也不需要额外的 flags 对象来保持同步。
+
+### Fork 与 fresh 是独立后端，而非一个 flag
+
+全新子 agent 与 fork 子 agent 是独立的提供方，而非请求中的一个 flag。`dsh-subagent-spawn` 启动隔离的子 agent；`dsh-subagent-fork` 用一个平衡前缀初始化子 agent，该前缀仅包含已完成的父轮次。进行中的轮次被排除，因为其 subagent 调用尚无结果，无法构成有效的回放历史。
+
+### 子 agent 隔离与父日志
+
+每个 subagent 运行在**自己的 `Session`** 中（独立 id、`parentSession` 谱系），独立持久化。父日志仅记录 spawn `tool/call` 及其 `tool/result`（子 agent 的最终输出）——子 agent 的内部步骤和工具调用留在子 agent 自己的会话中，绝不注入父日志。这是唯一在所有传输方式下行为一致的设计：ACP 子 agent 的内部事件在物理上无法注入我们的父日志，因此让进程内行为保持一致，使 seam 真正与传输方式无关。
+
+### 同步收集（首版）
+
+`dsh-tool-subagent` 将其执行信号传给 `start()`，等待子 agent 结果，并在 `finally` 中 dispose 该 run。非完成态的结果变为错误结果，而非成功的部分输出。这个前台消费方不使用 run 的可选 steering 方法。
+
+### 提供方选择是配置，不面向模型
+
+`dsh-tool-subagent` 绑定到恰好一个提供方名称（`Config.provider`）；模型只看到 `{ description, prompt }`。若要暴露多种传输方式，请多次加载该工具插件，每次绑定不同的提供方和不同的 `toolName`（工具注册表拒绝重名）。*服务*持有多提供方注册表；*工具*选择其中一个——本版 schema 中没有提供方/type 参数。
+
+## 测试
+
+注册表与工具测试仅用包内脚本化提供方替换非确定性的子进程边界，同时运行真实的 `SubagentService`、生命周期、任务集成和面向模型的工具。提供方与消费方的 export 形状仍保留 Loader 回归覆盖，以防止[事后分析 0001](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md) 中描述的失败。注册表测试覆盖重载安全性、重名和启动时能力拒绝；嵌套 agent 场景通过[逐会话快照回放](../testing/2026-06-22-subagent-snapshot-replay.md)进行无密钥回放；进程内后端还有真实循环的单元测试和带密钥的 e2e 测试。
+
+## 后果
+
+- **递归。** 如果不设限制，进程内子 agent 能看到委派工具并递归调用。进程内后端实现了可选的绝对深度限制和有作用域的实时全局 `toolFilter`；ACP 声明这两项能力为关闭状态，并拒绝此类请求。[subagent 组合控制 Agent Note](2026-07-12-subagent-persona-tool-filter-and-depth.md) 负责定义它们的确切语义和安全边界。
+- **阻塞父轮次。** 前台收集在子 agent 的整个持续时间内保持父 agent 的步骤打开。后台委派使用共享的 `ctx.tasks` 运行时与通用 `task_*` 工具，与后台 bash 共用同一套收集机制；subagent seam 本身仍不感知任务。
+- **实时进度。** 本版仅暴露生命周期事件与最终结果；逐分片的子→父更新流推迟到后台重新设计时一并处理。
+- **ACP 客户端接口。** 将 ACP 子 agent 的 `fs`/`terminal` 代理回父 agent（共享工作区模式）是后续工作；首版不声明这两项能力，子 agent 在自己的进程中自行服务。

## Problem
The subagent seam ([the seam Agent Note](2026-06-21-subagent-capability-seam.md)) was built so multiple backends coexist by name on `ctx.subagents`. The in-process backends (`-spawn`/`-fork`) run a child as a second `Agent` on the SAME cordis context — cheap, but the child shares the parent's process, model client, and tools. The seam's whole point was to also support an OUT-OF-PROCESS child reached over a protocol, proving the abstraction generalizes across a process boundary. This Agent Note adds the first such backend: an Agent Client Protocol (ACP) client.

+# Agent Note: ACP subagent 后端（进程外委派）
+
+Status: implemented
+
+[English](2026-06-22-acp-subagent-backend.md) | 中文
+
+## 问题
+
+subagent seam（[seam Agent Note](2026-06-21-subagent-capability-seam.md)）的设计使多个后端可以按名称共存于 `ctx.subagents`。进程内后端（`-spawn`/`-fork`）将子 agent（智能体）作为第二个 `Agent` 运行在同一个 Cordis 上下文上：开销低，但子 agent 与父 agent 共享进程、模型客户端和工具。seam 的核心意义在于同时支持通过协议到达的进程外子 agent，以证明该抽象能跨越进程边界泛化。本 Agent Note 添加第一个此类后端：一个 ACP（Agent Client Protocol）客户端。
+
+## 决策
+
+`@deepseek-ai/dsh-subagent-acp` 注册一个 `SubagentProvider`，将每个子 agent 运行在一个派生的子进程中，并以 ACP *客户端*身份驱动它。它是现有服务端桥接 `@deepseek-ai/dsh-acp`（ACP *agent*）的方向反转孪生体：桥接应答 `initialize`/`newSession`/`prompt`；本后端调用它们并实现 `Client` 回调（`sessionUpdate`、`requestPermission`）。将配置的 spawn 命令指向 `acp-agent` 示例，即可让 harness 与自身进程通信。
+
+### 每次运行启动全新进程
+
+每次 `start` 都 spawn 一个新的子进程，运行恰好一个 ACP 会话（`initialize` → `newSession` → `prompt`），`dispose` 杀死子进程并等待其退出。这是最简单的生命周期，与进程内「每次运行一个子 agent」的形态一致。
+
+### 最小化客户端桩
+
+客户端不声明任何可选能力（无 `fs`、无 `terminal`）：子 agent 在自己的进程中自行处理文件/终端访问。`session/update` 通知被消费：后端将 `agent_message_chunk` 文本累积为结果输出，在本阶段忽略其余内容（思考、工具调用卡片），仅暴露子 agent 的最终回答。`session/request_permission` 由配置的策略自动应答（`reject` 拒绝所有提示，`allow` 通过第一个允许形态的选项批准）——本阶段不向人类暴露任何权限提示。将 `fs`/`terminal` 代理回父进程（共享工作区模式）仍为后续工作，如 seam Agent Note 所述。
+
+### 无启动时能力
+
+提供方的 `capabilities` 全部为 `false`。进程外子 agent 无法遵守父 agent 的 `maxDepth`（它无权访问 `parent.options.subagentDepth`）或 `toolFilter`（它拥有自己的工具注册表），本阶段也未实现 `outputSchema`。如果请求需要其中任何一项，服务在 `start` 运行前即拒绝。后端仅注入 `subagents`（而非 `ctx.agents`）；它从 `request.parent` 读取的唯一内容是会话 header 的 cwd（见下方工作区解析）——对话上下文、深度和工具状态都不会跨越进程边界。
+
+### 工作区 cwd 解析
+
+子进程工作目录来自显式解析，绝不使用 harness 进程的 cwd：若已配置部署 `cwd` 覆盖，则相对于启动目录将其转为绝对路径并在加载时验证；否则使用父会话 header 的 cwd 并在启动时验证；如果两者都不存在，则在生成任何进程前大声拒绝。一个 ACP 服务端进程会服务来自多个工作区的会话，因此 `process.cwd()` 不能代替会话工作区——旧的隐式回退会让子进程在服务端启动目录中运行。候选路径必须是 harness 可以进入的绝对目录（要求 `X_OK`；仅 `statSync().isDirectory()` 会接受 mode-600 的目录，而 spawn 会因 EACCES 失败）；解析出的同一路径同时用作子进程 cwd 与 ACP `session/new` 工作区。
+
+### StopReason 映射
+
+ACP `StopReason` → harness `SubagentStopReason`：`end_turn`→`completed`、`max_tokens`→`max-tokens`、`refusal`→`refusal`、`cancelled`→`aborted`、`max_turn_requests`→`error`（无对等语义，任务未完成）、未知→`error`。spawn/传输/RPC 失败解析为 `error`（如果已请求取消则为 `aborted`）；按 seam 契约，`result` 在子 agent 级别失败时从不 reject。
+
+### 安全：清洗子进程环境
+
+子 agent 是独立进程，因此会继承环境变量。形如凭证的环境变量（`/KEY|SECRET|TOKEN/i`）默认不转发——父 harness 自身的密钥不得隐式泄露到派生进程中（与 bash 执行器采用的策略相同）。子 agent 自己的凭证（它需要模型密钥）通过 `config.env` 显式提供，在清洗之后叠加，因此有意传入的 `DEEPSEEK_API_KEY` 得以保留，而偶然存在的 `AWS_SECRET_ACCESS_KEY` 则不会。子进程的 stderr 继承到父进程的 stderr（诊断信息自然浮现）；spawn 级别的 `error` 事件（如命令不存在时的 ENOENT）被捕获并与 ACP 驱动竞速，因此错误命令解析为 `error` 而非以未处理错误崩溃父进程。
+
+## 测试
+
+- **无需密钥的单元/集成测试：** 一个脚本化的 ACP 子进程通过真实 stdio 测试提示词/输出流、所有 stop-reason 映射、信号与 dispose 取消（包括 pre-abort、会话前竞态和管道断裂场景）、两种权限策略、被忽略的非消息更新、命令缺失时的清理、提供方重载以及命名空间导出。
+- **无需密钥的 Loader 组合测试：** 仅用于测试的 cordis.yml 通过真实 Loader 启动 stdio 应用，并省略后端的 `cwd`；脚本化模型委派一次，脚本化子进程则证明它在父会话工作区中运行，且 ACP 也对外公布了该工作区，从而端到端覆盖 cwd 继承分支。
+- **需要密钥的 e2e 测试：** 后端 spawn 真实的 ACP 示例；其模型回答 `PONG`，写入 `proof.txt`，父进程验证该文件。
+- **快照缺口：** 每个 ACP 子 agent 是独立进程，拥有自己的回放会话，不同于进程内的按会话回放。确定性 mock 服务器覆盖率已具备；`TODO(acp-subagent-replay)` 跟踪父进程对回放中子 agent 的回放支持。
+
+## 曾考虑的替代方案
+
+### 为何继续使用 SDK 0.25.1？
+
+后端只需要 `ClientSideConnection`、`ndJsonStream`、`PROTOCOL_VERSION` 和客户端协议类型，0.25.1 全部支持。0.28 的 fluent API 需要在 ACP 层同时迁移客户端和服务端连接类，却不会改善本后端，因此升级作为独立变更保留。
+
+### 为何不使用持久子进程？
+
+持久进程池（跨运行复用热子进程）是一项性能优化，推迟到后续工作。它增加了会话生命周期和崩溃恢复的复杂度，本阶段不需要；每次 `start` spawn 全新子进程与进程内「每次运行一个子 agent」的形态一致。
+
+## 后果
+
+每次运行都要付出一个全新子进程的代价（spawn + `initialize` + `newSession`）。父进程仅暴露子 agent 的最终回答：`session/update` 中的思考和工具调用卡片被消费后丢弃，权限提示从不到达人类——由配置的策略应答。子进程环境默认经过凭证清洗，因此其自身的模型密钥需通过 `config.env` 显式提供。
+
+## 后续提供方
+
+同样的进程外启动/提示词/流式输出/取消形态可泛化到 seam Agent Note 中列出的其他传输方式——A2A、Codex app-server 和 Claude Code Agent SDK——每个都是按名称注册的兄弟提供方。ACP 后端证明了 seam 支持跨进程边界；其余在机制上类似。

## Problem
The agent sometimes cannot proceed safely from model inference alone: it needs the human to choose a path, confirm a risky/default action, or provide missing information. Before this change, the only way to get that answer was for the model to ask in assistant text and then stop, which broke the normal tool-call loop: the agent had no structured way to pause, no option metadata for UIs, no abort/error taxonomy, and no way for non-stdio front doors to present the question consistently.

Providers return `{ answers: [{ id, selected, custom? }] }`. `selected` is always an array of selected option labels, so single-select and `multi_select` answers share one result shape. `custom` carries a free-text "Other" answer; optionless questions collect `custom` directly. When `custom` is present, it overrides any selected choices and `selected` is empty. A provider that supports partial completion represents a deliberately skipped item with the existing `{ id, selected: [] }` shape, preserving the other answers without extending the tool result vocabulary.
-`UserInteractionError` extends `HarnessError`, so failures such as `NO_PROVIDER`, `ASK_ABORTED`, ACP cancellation, or missing session routing survive `ctx.tools.execute()` as machine-routable `{ name, code }` tool errors.

-`dsh-acp` provides the same seam for ACP sessions. It resolves the calling `Agent` through `ownedRecord`, requiring the forward session-map record at `agent.session.id` to own that exact agent object, and calls ACP `unstable_createElicitation` with a session-scoped form for each question. Single-select options become a `choice` string enum; `multi_select` options become a `choice` array enum; optionless questions use a required `custom` text field. If the client returns both `choice` and non-empty `custom`, the custom answer wins. ACP `decline`/`cancel`, a missing answer, a missing session, and a client without elicitation support all become structured `UserInteractionError`s.
-
-The ACP mapping deliberately uses elicitation, not `session/request_permission`. `request_permission` is still reserved for the separate permission gate: it is a yes/no-or-policy authorization protocol around tool execution. `ask_user_question` is a general information-gathering tool with optional free-form answers, so ACP form elicitation is the closer protocol fit. The bridge's session routing is shared with the future permission gate, but the user intent is different.

**Core-owned ask-user packages.** The first implementation split the seam and the model-facing tool across `packages/core` and `packages/ui`, but both names describe one UI-backed human-interaction affordance. The seam remains provider-neutral, but it is not providerless core infrastructure like sessions, tools, or the agent registry. Keeping `dsh-user-interaction` and `dsh-tool-ask-user` together under `packages/ui` makes the package map match the product boundary: apps and bridges provide the human-answer provider, and the stdio app opts into the model-facing tool.
-**ACP `session/request_permission`.** Permission requests are authorization around tool execution; `ask_user_question` is information gathering with optional free-form answers.

+**Use a permission request for general questions.** Permission requests authorize tool execution; `ask_user_question` gathers information with optional free-form answers. Reusing the permission channel would collapse two different product concepts.
**A loop-level pause primitive.** The agent loop already knows how to await a tool call and resume from a tool result. Adding a new loop special case would duplicate that async shape and make every loop implementation learn about a UI concern.
## Consequences
-ACP elicitation is currently marked unstable in the SDK. The fallback is still structured: if a client does not implement it, the tool returns `ASK_FAILED` rather than hanging. A later ACP stabilization may rename or reshape the method; that migration should stay inside `dsh-acp` because the core `ctx.userInteraction` vocabulary is provider-neutral.
-
The feature gives the model a powerful pause primitive, so prompt guidance matters. The tool description tells the model to ask concise questions and use options when possible. Product policy can later wrap `tools/execute` to restrict when the tool is allowed, but the loop should not special-case it.
-`dsh-user-interaction` and `dsh-tool-ask-user` both live in `packages/ui` because they form one product-facing human-interaction capability. `agent-core` does not load either the tool or a provider. `dsh-tui-demo` opts into the seam, TUI provider, and model-facing tool. `dsh web` boots the seam/provider in the host runtime and exposes the tool through the selected Web question plugin. `acp-agent` keeps only the `userInteraction` seam/provider by default: ACP elicitation support is still client-dependent, so an ACP leaf must opt into the model-facing tool deliberately once its client can complete elicitation requests.

The ACP automation app mounts neither the seam nor the tool.
## Testing
-Unit coverage pins provider registration/disposal, duplicate-provider rejection, abort-before-provider, empty-question rejection, structured tool errors through `ctx.tools.execute()`, batched answers, multi-select answers, custom answers, explicit per-item skips, and the model schema including the removal of `value`, `recommended`, `allow_custom`, and `desc`.

ACP bridge tests drive a real in-memory ACP connection with the real `ask_user_question` tool and verify selected-option, custom-overrides-choice, multi-select, and optionless free-form elicitation paths continue the agent loop.

+# Agent Note: ask-user 提问能力
+
+Status: implemented
+
+[English](2026-06-25-ask-user-question.md) | 中文
+
+## 问题
+
+agent（智能体）有时仅凭模型推理（inference）无法安全地继续执行：它需要人类选择路径、确认有风险的或默认的操作，或者提供缺失的信息。在此变更之前，获取答案的唯一方式是模型在 assistant 文本中提问然后停止，这打断了正常的工具调用循环：agent 没有结构化的暂停方式，没有供 UI 使用的选项元数据，没有中止/错误分类体系，也没有让非 stdio 前端一致地呈现问题的途径。
+
+这是一个面向用户的能力，但它也跨越了包（package）边界。面向模型的工具需要一套提供方无关的请求词汇；每个 UI 界面需要决定如何展示和收集答案；agent loop（智能体循环）应保持不变，因为工具调用本身已具备正确的异步形状。
+
+## 决策
+
+引入 `dsh-user-interaction` 作为 `ctx.userInteraction` 的提供方无关接口包，与面向模型的消费方 `dsh-tool-ask-user` 一同放在 `packages/ui` 下。这一分组是有意为之的：向人类提问是一种由 UI 支撑的产品功能，不属于无提供方的核心主干。seam 仍然拥有稳定的请求/应答/错误词汇，而 UI 产品界面提供收集答案的具体提供方。该工具注册 `ask_user_question`，转发 `{ questions, agent, signal }`，并将提供方计算出的结构化答案作为工具结果返回。
+
+面向模型的请求词汇有意与产品调研 schema 对齐：`ask_user_question({ questions: [{ id, question, header?, options?: [{ label, description? }], multi_select? }] })`。`id` 按问题提供并在结果中回传，使批量请求无需依赖问题文本即可路由。`label` 既是面向用户的显示文本，也是返回给模型的选中值；没有单独的 `value`，没有 `recommended`，没有 `allow_custom`，也没有 `desc` 别名。
+
+提供方返回 `{ answers: [{ id, selected, custom? }] }`。`selected` 始终是选中选项 label 的数组，因此单选和 `multi_select` 的答案共享同一种结果形状。`custom` 承载自由文本的「其他」答案；无选项的问题直接收集 `custom`。当 `custom` 存在时，它覆盖任何已选择的选项，`selected` 为空。支持部分完成的提供方使用现有的 `{ id, selected: [] }` 形状表示某项被有意跳过，在不扩展工具结果词汇的前提下保留其他答案。
+
+`UserInteractionError` 继承 `HarnessError`，因此 `NO_PROVIDER`、`ASK_ABORTED` 或请求归属缺失等失败会以机器可路由的 `{ name, code }` 工具错误形式通过 `ctx.tools.execute()` 传出。这与结构化错误分类体系一致，使模型或包装插件能够区分「用户取消」与一般的抛出异常。

+`dsh web` 挂载 `dsh-client-ui-question`：其 host 侧使 Web 产品选择性加载面向模型的工具，浏览器侧则在 conversation 拥有的具名输入区 slot 中注册 `question` 项。`createApiProxy` 使用以 host 生成的 rpcId 为键的进程内 pending 表实现 Web 提供方。它先注册等待项，再广播 `question/requested`；每次 mux 重开时以相同 id 重放；在受理前校验会话和完整答案批次；并在回答、取消、中止或资源释放后广播 `question/resolved`。受理会同步删除该条目，因此首个有效响应胜出，重复或迟到的响应返回 `not-pending`。
+
+Web 输入区一次显示一个问题，同时在会话对象层保留每个请求。它支持单选、多选、无选项问题或显式自定义答案、描述文本与可视化推荐标记，但不会自动选中推荐项。选择单选项后会立即进入下一项；当所有项都已回答或显式跳过时，按 Enter 提交；IME 组字期间按 Enter 只会确认输入候选项。页脚只跳过当前项并保留先前的草稿；关闭控件以 `ASK_CANCELLED` 拒绝整个工具调用。常规输入区只有在 host 的 resolved 帧移除待处理项后才会恢复。
+
+`dsh-tui` 将每个问题渲染为键盘叠层，展示选项描述，支持单选、多选和自由格式自定义答案，并在中止、提供方 dispose（资源释放）或终端关闭时拒绝待处理的问题。批量请求和并发请求都会排队，确保同一时刻只有一个叠层占用键盘焦点。
+
+在桥接层还是编辑器 UI 时曾存在一个 ACP（Agent Client Protocol）elicitation 映射；[ACP 作为仅面向自动化的协议](../simplification/2026-07-23-acp-automation-only-protocol.md)移除了这第三个映射。
+
+## 曾考虑的替代方案
+
+**Assistant 文本后跟一个停止的轮次。** 模型可以在纯 assistant 文本中向用户提问然后停止。这会丢失结构化选项元数据，UI 没有提供方无关的方式来渲染选择，且下一条人类回答只能作为新的 user 提示词到达，而非作为需要答案的那次操作的结果。
+
+**核心拥有的 ask-user 包。** 最初实现将 seam 和面向模型的工具分别放在 `packages/core` 和 `packages/ui`，但两者描述的是同一个由 UI 支撑的人机交互功能。seam 仍然是提供方无关的，但它不是像会话、工具或 agent 注册表那样的无提供方核心基础设施。将 `dsh-user-interaction` 和 `dsh-tool-ask-user` 一起放在 `packages/ui` 下，使包的划分与产品边界一致：应用和 bridge 提供人类答案的提供方，stdio 应用选择性加载面向模型的工具。
+
+**用权限请求处理通用提问。** 权限请求是对工具执行的授权；`ask_user_question` 是带可选自由格式答案的信息收集。复用权限通道会混淆两个不同的产品概念。
+
+**循环级别的暂停原语。** agent loop 已经知道如何等待工具调用并从工具结果恢复。添加新的循环特殊分支会重复这一异步形状，并迫使每个循环实现都了解一个 UI 关注点。
+
+## 后果
+
+该功能赋予模型一个强大的暂停原语，因此提示词引导很重要。工具描述告诉模型：提问要简洁，尽可能使用选项。产品策略后续可以包装 `tools/execute` 来限制工具何时可用，但循环不应对其做特殊处理。
+
+`dsh-user-interaction` 和 `dsh-tool-ask-user` 都位于 `packages/ui`，因为它们共同构成一个面向产品的人机交互能力。`agent-core` 不加载工具或提供方。`dsh-tui-demo` 选择性加载 seam、TUI 提供方和面向模型的工具。`dsh web` 在 host 运行时启动 seam/提供方，并通过选定的 Web question 插件暴露该工具。ACP 自动化应用既不挂载 seam 也不挂载该工具。
+
+## 测试
+
+单元覆盖率固定了以下场景：提供方注册/释放、重复提供方拒绝、提供方就绪前中止、空问题拒绝、通过 `ctx.tools.execute()` 传出的结构化工具错误、批量答案、多选答案、自定义答案、显式按项跳过，以及模型 schema（包括移除 `value`、`recommended`、`allow_custom` 和 `desc`）。TUI 测试覆盖选项描述、排队请求、关闭/中止清理、无选项自由格式输入、无效选择、重复多选和批量问题流。Web 测试固定稳定 id 重放、响应校验、首个响应胜出的结算、重复和迟到响应、整个请求的取消与拥有方中止的区别、单选后前进、IME 安全的 Enter 提交、按项跳过保留、输入区接管、结构化批量提交，以及常规输入区的恢复。

## Problem
-The harness gives the model bash and subagent tools but no way to record a structured task list. A todo list serves two co-equal purposes: it steers the model to plan multi-step work and keep the active task unambiguous (at most one active, exactly one while work remains), and it gives the human a live progress checklist. The ACP protocol has a native `plan` sessionUpdate that editors (Zed) already render, but the bridge never emitted one. Every reference coding agent surveyed (claude-code, opencode, codex, oh-my-pi, pi) ships some form of this; the harness had nothing.

## Decision
-Add a model-facing `todo_write(todos: [{ content, status }])` tool whose whole-list state lives on the event-sourced session log as a new `todo/write` `SessionEventMap` variant. Both the stdio UI and the ACP bridge render off the existing `session/event` — the ACP bridge maps the list to a `plan` sessionUpdate.

Interactive hosts render from the durable event; the TUI folds it directly, while the [automation-only ACP bridge](../simplification/2026-07-23-acp-automation-only-protocol.md) deliberately omits todo presentation.
### Whole-list replace, three-state status
-The model sends the ENTIRE list every call; the new list replaces the old (last-write-wins on replay). This is the shape claude-code V1, opencode, and codex `update_plan` all use, and the shape the model is most trained on — no per-item ids, no delta protocol. `status` is exactly `pending | in_progress | completed`: the same triple as codex `update_plan` and, crucially, **identical to the ACP `PlanEntryStatus`**, so the bridge maps it 1:1 with no lossy translation.

### State on the session log, not a service
-The list is appended as a `todo/write` event carrying the full `{ todos }` snapshot. The harness is event-sourced — the LLM history, tool calls, and turn structure all live on the log — so the todo list lives there too. This buys durability, replay, and `session/load` reconstruction for free: a reopened session re-derives the current list (the last `todo/write`) and the ACP bridge re-emits the `plan` on load, with no separate persistence backend, no in-memory service to rehydrate, and no extra wiring. An in-memory `ctx.todos` service would have had to reinvent all of that.

An in-memory `ctx.todos` service would have to reinvent all of that.
### NOT a surface event
`todo/write` is deliberately excluded from `SurfaceEventType`. The surface is the projection that produces the LLM message history (`deriveMessages()`); a todo write produces no conversation message. So it carries no `surfaceOp`, never joins the ordered surface, and never reaches `deriveMessages()` — it is durable, replayable *UI* state that travels alongside the conversation without being part of it. (The dev-mode invariants still require it to sit inside an open turn, which it always does: it is appended mid-step during a tool call.)
-### Priority synthesized only at the ACP boundary
-
-ACP's `PlanEntry` requires `content` + `priority` + `status`, but a `TodoItem` has no priority — the model never reasons about it. Rather than burden the schema with a field the model must always supply, the bridge synthesizes a constant `priority: 'medium'` on every entry when it builds the `plan`. Priority is an ACP wire requirement, not a harness concept, so it lives at exactly the boundary that needs it.
-
### Dropped vs claude-code V1: `activeForm`, id, priority
-claude-code V1's item is `{ content, status, activeForm }`; later (V2) it grew ids, dependencies, and ownership — but only to support agent *swarms* (disk-backed, lock-guarded, per-item mutation). This tool keeps the item at the minimum: `{ content, status }`. No `activeForm` (the present-continuous label) — the UI shows `content`; no id — whole-list replace needs no stable identity; no priority — see above. Each dropped field is one less thing the model must produce on every call.

- **Real-Loader path** — the plugin run through `Loader.unwrapExports`, asserting the namespace export shape survives (it HAS `inject`, so a stray default would crash at load — postmortem/0001).

Whole-list replace means one tool call per update with last-write-wins; there is no delta protocol to reconcile. The event stays off the surface, so a todo update never perturbs the derived model history — the model sees only its own tool call and result.

+# Agent Note: `todo_write` 工具——将模型任务列表作为事件溯源的会话状态
+
+Status: implemented
+
+[English](2026-06-29-todo-write-tool.md) | 中文
+
+## 问题
+
+harness 为模型提供了 bash 和 subagent 工具，却没有办法记录结构化的任务列表。todo 列表有两个同等重要的用途：引导模型规划多步骤工作并保持当前活跃任务明确（最多一个活跃，有剩余工作时恰好一个）；同时为交互式宿主提供实时进度清单。调研的所有参考编码 agent（智能体）（claude-code、opencode、codex、oh-my-pi、pi）都提供了某种形式的此功能；本 harness 此前没有。
+
+## 决策
+
+新增一个面向模型的 `todo_write(todos: [{ content, status }])` 工具，其整列表状态作为新的 `todo/write` `SessionEventMap` 变体存储在事件溯源的会话日志上。交互式宿主从持久事件渲染；TUI 直接折叠它，而[仅面向自动化的 ACP（Agent Client Protocol）桥接层](../simplification/2026-07-23-acp-automation-only-protocol.md)有意省略 todo 展示。
+
+### 整列表替换，三态 status
+
+模型每次调用发送完整列表；新列表替换旧列表（回放时 last-write-wins）。这是 claude-code V1、opencode 和 codex `update_plan` 共同采用的形状，也是模型训练最多的形状——没有逐项 id，没有 delta 协议。`status` 恰好是 `pending | in_progress | completed`，与 codex `update_plan` 相同的三元组；在 bridge 还把 todo 列表投影为 `plan` 更新时，它也与 ACP `PlanEntryStatus` 1:1 对应，该映射已随[仅面向自动化的 ACP 契约](../simplification/2026-07-23-acp-automation-only-protocol.md)退役。
+
+### 状态在会话日志上，而非服务
+
+列表作为 `todo/write` 事件追加到日志，携带完整的 `{ todos }` 快照。harness 是事件溯源的——LLM（大语言模型）历史、工具调用和轮次结构都在日志上——所以 todo 列表也在那里。这免费获得了持久性、回放和恢复重建：重新打开的会话从最新的 `todo/write` 重新推导当前列表，无需独立的持久化后端、无需重新注水的内存服务、无需额外接线。一个内存中的 `ctx.todos` 服务需要重新发明以上所有。
+
+### 不是 surface 事件
+
+`todo/write` 被有意排除在 `SurfaceEventType` 之外。surface 是产出 LLM 消息历史（`deriveMessages()`）的投影；todo write 不产生对话消息。因此它不携带 `surfaceOp`，不加入有序 surface，不进入 `deriveMessages()`——它是持久、可回放的 *UI* 状态，与对话并行传输但不属于对话的一部分。（dev-mode 不变式仍要求它位于一个打开的轮次内，而它始终如此：它在工具调用的步骤中途追加。）
+
+### 相比 claude-code V1 舍弃的字段：`activeForm`、id、priority
+
+claude-code V1 的条目是 `{ content, status, activeForm }`；后来（V2）增加了 id、依赖和所有权——但仅为支持 agent *集群*（磁盘持久、锁保护、逐项变更）。本工具将条目保持在最小集：`{ content, status }`。不要 `activeForm`（现在进行时标签）——UI 直接展示 `content`；不要 id——整列表替换不需要稳定标识；不要 priority——它只曾是 ACP `PlanEntry` 的协议格式（wire format）要求，在 bridge 边界合成为常量而非建模，并已随该投影一起离开。每舍弃一个字段，模型每次调用就少产出一项。
+
+### 单一所有者——无集群机制（YAGNI）
+
+每个列表属于调用它的 agent 会话，非 agent 调用被拒绝。没有共享作用域、resolver 或 delta 协议。跨 agent 列表需要逐项日志 delta 和显式作用域选择，因此留作未来独立设计。
+
+### 校验：低成本的中间路线
+
+schema 强制 type/required/enum。在此之上，`execute` 拒绝为空或重复的 `content`，以及超过一个 `in_progress` 任务。claude-code 将单一 in_progress 交给提示词约束；oh-my-pi 在代码中强制。我们取中间路线：强制执行使计划*连贯*的低成本不变式（无空任务、无重复、最多一个活跃），但将排序和保持列表最新的纪律通过工具描述交给模型。被拒绝的写入返回 `isError` 结果，使模型自行修正。
+
+## 为何没有 cordis-catalog 条目 / 没有 `@mode`
+
+`todo/write` 是 `SessionEventMap` 的成员，不是一等的 cordis `interface Events` 事件。catalog 生成器（`scripts/gen-cordis-catalog.ts`）扫描 `interface Events` 声明；`SessionEventMap` 变体搭载现有的 `session/event` emit，不产生新的 catalog 行。因此它不携带 `@mode` 标签（生成器仅对 `interface Events` 成员要求该标签）——添加一个毫无意义。
+
+## 测试
+
+四个层级，预先设计：
+- **单元测试**——会话事件（append/snapshot-clone/last-write-wins/not-on-surface）；工具（schema 形状、通过真实 `ctx.tools.execute` 的参数校验、值校验、事件追加与替换、非 agent 拒绝、`presentCall`、HMR（热模块替换）安全性）；以及 TUI 折叠。
+- **真实 Loader 路径**——插件通过 `Loader.unwrapExports` 运行，断言命名空间导出形状存活（它有 `inject`，因此一个意外的 default 导出会在加载时崩溃——postmortem/0001）。
+- **全循环集成**——一个脚本化的 mock 模型通过真实 agent loop（智能体循环）调用 `todo_write`；`todo/write` 事件落地，第二次调用替换它。
+- **恢复/回放**——持久化的 `todo/write` 折叠回当前任务列表。
+- **带密钥 e2e + 快照**——真实提示词诱导 `todo_write`；组装后的快照固定日志事件和交互式渲染。
+
+## 曾考虑的替代方案
+
+- **内存中的 `ctx.todos` 服务**——需要重新发明日志免费提供的持久性、回放和恢复重建。
+- **逐项 delta 协议**——仅在共享多所有者列表时需要，超出当前范围；整列表替换更简单，且与参考实现一致。
+- **工具放在 `core/` 中**——`todo_write` 是注册在 `ctx.tools` 上的扩展工具，不属于主干；它像其他工具族一样位于自己的 `packages/todo/` 分组中。
+
+## 后果
+
+todo 列表是持久、可回放的会话状态：交互式宿主从最新持久化的 `todo/write` 重新推导它，日志（而非插件内存）是唯一真源。整列表替换意味着每次更新一次工具调用，last-write-wins；没有需要协调的 delta 协议。事件不进入模型 surface，因此 todo 更新永远不会扰动推导出的模型历史——模型只看到自己的工具调用和结果。

## Problem
The harness's extension surface is its typed interception seams ([the interception-seams Agent Note](2026-06-30-interception-seams.md)): a "native hook" is just an ordinary cordis plugin subscribing to `agent/session-start`, `agent/prompt-submit`, `tools/pre-execute`, `tools/post-execute`, `agent/turn-continuation`, `subagent/start`, `subagent/end`. But users arrive with **existing** Claude Code (CC) and Codex hook configs — a `hooks.json` (or a settings file's `hooks` key) full of shell-command hooks — and want those to run unmodified. This Agent Note introduces the two **bridge plugins** that translate that external shell-hook protocol onto the typed seams, built on the shared wire-protocol library ([the hook-protocol-lib Agent Note](2026-06-30-hook-protocol-lib.md)).

- **Stop loop-guard** (`TODO(stop-loop-guard)`). Claude Code supplies `stop_hook_active` and overrides a hook after eight consecutive blocks; Codex supplies `stop_hook_active` but documents no equivalent cap. Both bridges always report `false`, so a Stop hook that unconditionally blocks force-continues every step — a hook author must self-limit until state tracking lands.
- **Hook `continue:false` (hard halt).** A hook can ask to halt the whole run (CC/Codex `continue:false`); the shared merge folds it into `MergedHookOutcome.stop`/`stopReason`, but no bridge acts on it (`TODO(hook-continue-false)`) — the interception seams have no "hard-halt the agent" primitive yet (a Decision blocks/steers a single point, not the run). Deferred with the loop-guard work; the halt request is recorded in the `hook/result` log, and the hook keeps its per-point effect (decision/context) meanwhile.
- **Config discovery.** The path is explicit in `cordis.yml` and process-level (see above); the full multi-layer CC/Codex precedence walk, per-session project-local discovery, and the trust/hash model are not reimplemented (`TODO(per-session-hook-config)`).

+harness 的扩展面是其类型化的拦截 seam（见[拦截 seam Agent Note](2026-06-30-interception-seams.md)）：所谓「原生钩子」不过是一个普通的 Cordis 插件，订阅 `agent/session-start`、`agent/prompt-submit`、`tools/pre-execute`、`tools/post-execute`、`agent/turn-continuation`、`subagent/start`、`subagent/end`。但用户带着**既有的** Claude Code（CC）和 Codex 钩子配置到来，一个 `hooks.json`（或 settings 文件中的 `hooks` 键）里满是 shell 命令钩子，并希望它们原样运行。本 Agent Note 引入两个**桥接插件**，将外部 shell 钩子协议翻译到类型化 seam 上，构建于共享的协议格式（wire format）库之上（见 [hook-protocol-lib Agent Note](2026-06-30-hook-protocol-lib.md)）。
+
+贯穿整个设计的定位：**桥接是兼容性适配器，不是高级工具。** 桥接能做的事（阻止工具、注入上下文、强制继续、观察 subagent），原生 Cordis 插件都能做得更强——类型化返回值、完整 `ctx`、无序列化边界。桥接存在的理由是运行外部 CC/Codex 命令钩子中被明确支持的子集。这使每个桥接保持精简：解析配置、选择匹配模式、构建每事件的 payload、调用共享库的 `runHook` + `mergeHookOutputs`，再将中性结果映射为 seam Decision。各包的 README 维护着当前不支持的事件和部分字段的完整清单，以官方协议为参照。
+
+## 决策
+
+`packages/hooks/` 组下两个独立插件，各为 function/namespace 插件（`name`/`inject`/`Config`/`apply`，无 default export——见[事后复盘 0001](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md)），仅注入 `bash`：
+
+- **`dsh-hooks-claude`**——CC 方言。Claude Code 当前七个钩子点中的七个：`SessionStart`、`UserPromptSubmit`、`PreToolUse`、`PostToolUse`、`Stop`、`SubagentStart` 和 `SubagentStop`。拥有 CC 形态的每事件 stdin payload（基础字段 `session_id`/`transcript_path`/`cwd`/`hook_event_name` 加每事件字段）、`CLAUDE_PROJECT_DIR` 环境变量加 `${CLAUDE_PLUGIN_ROOT}`/`${CLAUDE_PROJECT_DIR}` 替换，以及字面量或正则的匹配模式。`transcript_path` 是持久化定位器结果或 `''`；stdin 带有**尾部换行**。
+- **`dsh-hooks-codex`**——Codex 当前五个钩子点中的五个：`PreToolUse`、`PostToolUse`、`SessionStart`、`UserPromptSubmit` 和 `Stop`。使用始终为正则的匹配模式、Codex 形态的 snake_case payload（含 `turn_id`/`model`/`permission_mode` 额外字段），写入时不带尾部换行，不注入 Codex 插件环境变量，不做配置时占位符替换，也没有 pre-tool 审批或重写路径。`transcript_path` 是同一定位器结果或 `null`；工具 payload 在精简后的 `tool_input: { command }` 形态中携带真实的 `tool_name`。
+
+### Outcome → Decision 映射
+
+每个桥接将共享库返回的中性 `MergedHookOutcome` 映射到 seam 的类型化 Decision：
+
+| Seam | CC | Codex |
+|---|---|---|
+| `agent/session-start`（emit） | additionalContext → `agent.inject()` | 纯 stdout 输出 → additionalContext → `agent.inject()` |
+| `agent/prompt-submit` | `deny`→`block`；仅上下文→delegate+fold | `block`→`block`；仅上下文→delegate+fold |
+| `tools/pre-execute` | `deny`→`deny`；`ask`→`ask` | `block`→`deny`（无 allow/ask） |
+| `tools/post-execute` | `deny`→`block`+feedback；仅上下文→delegate+fold | 同上 |
+| `agent/turn-continuation` | 阻塞的 Stop → `continue`（reason = 下一步 steering（中途引导）） | 同上 |
+| `subagent/start`（emit） | additionalContext → 注入到存活的进程内 subagent；远程 subagent 无本地注入目标 | 本桥接不支持 |
+| `subagent/end`（emit） | 仅观察 | 本桥接不支持 |
+
+CC 桥接的 `ask` 结果是一条真正的权限路径，而非终态桥接决策：`dsh-tools` 通过可选的[审批 seam](2026-07-06-approval-seam.md) 来解析它。ACP 自动化客户端可以应答所属会话的一次性机器策略请求，`allowed-once` 后继续执行；如果没有 ApprovalService 或应答器，调用以 `deny` 安全关闭。
+
+### 上下文来源始终是插件（误标签防护）
+
+`agent.inject()` 在缺少 `MessageSource` 时默认为 `{ kind: 'user' }`，因此每个桥接的 `inject()` 和 `HookContext` 都传入 `{ kind: 'plugin', plugin: 'hooks-claude' | 'hooks-codex' }`。单元测试覆盖率固定验证结果中的 `context/message.source` 为插件而非用户。
+
+### 添加上下文不是否决——先 delegate，再 prepend
+
+仅附加 `additionalContext`（没有 block/deny）的钩子并不是桥接可以独自返回的决策：在 waterfall 监听器中不调用 `next()` 就返回 `allow`/`accept`，会短路其后的每个 `agent/prompt-submit` / `tools/post-execute` 监听器，使注册在桥接之后的策略/沙箱插件看不到该提示词。因此，每个桥接都会先通过 `next()` 委托，再将自身上下文加入下游决策。两个 seam 都携带有序的 `additionalContexts` 数组，因此桥接会在保留所有下游来源、信封和元数据字段的同时，前置加入其独立来源的条目；下游提示词阻止仍会丢弃所有上下文，因为提示词从未到达模型，而工具后阻止语义可以显式保留上下文。Code Mode 会通过外层 `run_code` 结果转送同一数组。只有钩子本身真正返回 `deny`/`block` 才会短路。测试断言：上下文钩子允许后，较晚的监听器仍能阻止提示词，且保留的提示词和工具后上下文仍彼此分离。
+
+### CLAUDE_PROJECT_DIR 默认为会话工作区
+
+Claude Code 始终导出 `CLAUDE_PROJECT_DIR`，常见的未修改钩子引用 `$CLAUDE_PROJECT_DIR` 来构造项目相对路径。显式的 `config.projectDir` 优先；当它被省略时（默认 ACP 接线只配置 `configPath`），桥接将该环境变量按每次运行默认为 agent（智能体）的会话工作区——即钩子已经在其中运行的 `session.header.cwd`——而非留空。这样，一个标准的项目相对路径钩子在默认配置下即可正常工作。
+
+### 隔离
+
+配置在加载时一次性解析；读取/解析失败时记录日志并不注册任何内容，而非崩溃启动（一个拼错的路径不应拖垮 agent）。CC 桥接只运行 shell 形式的 `type: 'command'` 钩子；`http`、`mcp_tool`、`prompt` 和 `agent` 处理器被解析后跳过。Codex 桥接只运行同步命令处理器，跳过 `async: true` 或非命令条目。emit 监听路径（`session-start`、`subagent/start`）以 detached 方式运行，其 `inject` 包裹在 `.catch` 中记录日志（抛异常的 inject 不得中断会话启动或循环）。
+
+### 钩子在哪里运行，配置从哪里来
+
+钩子在 agent 的会话工作区中运行，因此相对路径指向用户的项目。`configPath` 相对于进程启动时的 cwd 解析一次，适用于所有会话。按会话的项目本地发现仍推迟在 `TODO(per-session-hook-config)` 下。
+
+## 推迟的兼容性缺口
+
+- **工具输入重写。** CC/Codex 的 `updatedInput` 被记录日志并发出警告，但不予执行——输入重写是一个推迟的一致性设计问题（见 [pre-tool-input-rewrite Agent Note](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md)），因为 pre-execution 参数被 `tool/call` 审计、`assistant/message` 历史和工具展示共同读取，诚实的重写是一个设计单元，而非一个字段。
+- **Stop 循环防护**（`TODO(stop-loop-guard)`）。Claude Code 提供 `stop_hook_active` 并在连续八次阻塞后覆盖钩子；Codex 提供 `stop_hook_active` 但未记录等效上限。两个桥接始终报告 `false`，因此一个无条件阻塞的 Stop 钩子会在每一步强制继续——在状态追踪落地之前，钩子作者必须自行限制。
+- **钩子 `continue:false`（硬停止）。** 钩子可以请求终止整个运行（CC/Codex `continue:false`）；共享合并将其折叠为 `MergedHookOutcome.stop`/`stopReason`，但没有桥接对其采取行动（`TODO(hook-continue-false)`）——拦截 seam 尚无「硬停止 agent」原语（Decision 阻塞/引导的是单个点，而非整个运行）。与循环防护工作一同推迟；停止请求记录在 `hook/result` 日志中，钩子在此期间保留其逐点效果（决策/上下文）。
+- **配置发现。** 路径在 `cordis.yml` 中显式指定且为进程级（见上文）；完整的多层 CC/Codex 优先级遍历、按会话的项目本地发现以及信任/hash 模型未被重新实现（`TODO(per-session-hook-config)`）。
+- **Session-start / subagent-start 上下文为尽力而为（`TODO(session-start-gating)`）。** 两个钩子以 detached 方式运行于启动过程之外，因此其上下文在就绪时注入，但可能错过首个请求或短命的 subagent。要保证首请求送达，需要一个 awaited 的启动 seam。
+
+## 曾考虑的替代方案
+
+**每点钩子并发执行。** 参考引擎对一个点匹配到的钩子并发运行并折叠结果。本桥接**串行**运行（匹配循环内每个钩子 `await`），并以相同的最严格合并策略折叠。串行是刻意的：它使每个钩子的 `hook/invoked`/`hook/result` 对在会话日志中相邻且顺序确定，而折叠对决策是顺序无关的（`deny > ask > allow`），因此结果一致。代价是延迟（钩子 *N* 等待钩子 *N−1*）以及每钩子超时不重叠——对真实配置中的钩子数量可以接受；如果某配置的扇出大到影响总耗时，再重新评估。
+
+## 后果
+
+匹配语义、退出码处理和合并优先级位于 `dsh-hook-protocol`；每个桥接只负责解析配置、构建方言 payload 和映射结果。逐文件覆盖率包含配置分支以及通过真实循环、`dsh-bash-local` 和 shell 脚本的端到端映射，同时一个真实 Loader 冒烟测试守护包的导出形态。原生插件绕过协议格式，直接返回类型化决策。

## Problem
The hooks subsystem ships two bridge plugins: one that runs a user's existing Claude Code (CC) hooks, one for Codex hooks. Studying the reference implementations (`~/repos/refs/claude-code`, `~/repos/refs/codex`) surfaced a decisive fact: **Codex deliberately reimplements a SUBSET of the CC hook protocol.** Its engine reads the same `hooks.json`, uses the same matcher-group shape, the same exit-code/structured-stdout output contract, and the same command-hook execution model — Codex's source even names the engine after Claude's and comments where it "intentionally diverges." So the two bridges would otherwise duplicate the bulk of the protocol.

+# Agent Note: dsh-hook-protocol——Claude Code / Codex 钩子协议格式共享核心库
+
+Status: implemented
+
+[English](2026-06-30-hook-protocol-lib.md) | 中文
+
+## 问题
+
+钩子子系统提供两个桥接插件：一个运行用户既有的 Claude Code（CC）钩子，另一个运行 Codex 钩子。研究参考实现（`~/repos/refs/claude-code`、`~/repos/refs/codex`）后发现一个决定性事实：**Codex 有意重新实现了 CC 钩子协议的一个子集。** 它的引擎读取相同的 `hooks.json`，使用相同的 matcher-group 形状、相同的 exit-code/structured-stdout 输出契约，以及相同的命令钩子执行模型。Codex 的源码甚至以 Claude 的引擎命名，并在注释中标注了「有意偏离」之处。因此，如果不做抽取，两个桥接插件将大量重复协议逻辑。
+
+本 Agent Note 引入 `@deepseek-ai/dsh-hook-protocol`，一个**库**（不是插件——它不注册也不注入任何东西），持有两个桥接插件共同依赖的真正相同的原语。共享与方言专属之间的分界是本设计的重心。
+
+## 决策
+
+在 `packages/hooks/` 分组下新建 `hook-protocol` 作为纯库。它拥有四个原语族和 `hook/*` 会话事件；每个桥接插件（`dsh-hooks-claude`、`dsh-hooks-codex`）拥有真正不同的部分。
+
+**共享（本库）：**
+- **Matcher** — `matchesMatcher(pattern, query, mode)`。两种方言唯一不同的轴被收敛为 `mode` 参数：`claude` 将纯 `[A-Za-z0-9_|]+` 模式视为字面量（管道符 = 精确匹配的多选），其余视为正则；`codex` 始终是无锚定正则。缺省/`''`/`'*'` 匹配一切；无效正则匹配空集（绝不向 agent loop（智能体循环）抛异常）。
+- **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
+- **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
+- **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。
+- **`hook/*` 会话事件** — `hook/invoked` / `hook/result`，通过声明合并进入 `SessionEventMap`（仅日志，如 `compact/*`——不是 `SurfaceEventType`），配有 `appendHookInvoked`/`appendHookResult` 辅助函数，确保 invoked/result 配对与轮次包含关系在各桥接插件间保持一致。`appendHookResult` 还拥有持久化记录的语义：decision 字符串（钩子解析出的 decision，否则 `continue:false` 时为 `'stop'`，否则为 `'pass'`）和 500 字符的 `stderrSummary` 截断均从本库的 `HookOutput` 派生，而非各桥接插件各自实现。
+
+**方言专属（桥接插件）：** 构建每个事件的 stdin payload（CC 的 base+per-event 字段集 vs Codex 的 snake_case 加 `turn_id`/`model` 额外字段）、方言的 env 与 `${CLAUDE_PLUGIN_ROOT}` 替换（CC）vs 无替换（Codex），以及将方言无关的 `HookOutput`/`MergedHookOutcome` 映射为 harness seam 专属的类型化 Decision（`PreToolDecision`、`PromptDecision`、`ContinuationDecision`、`PostToolDecision`）。
+
+## 曾考虑的替代方案
+
+**单一参数化引擎。** 否决，因为 payload 构建与 decision 映射在方言间确实不同。Matcher、编解码器、执行、合并规则和事件保持共享；每个桥接插件保留自己的 payload 和映射，使其协议格式行为在代码中可就地阅读。
+
+## 后果
+
+每个桥接插件解析配置、构建方言 payload、调用共享的 runner 与合并逻辑、映射 decision、追加 `hook/*`。协议测试覆盖每种 matcher 模式、exit-code 与编解码器字段、runner 管道、合并优先级和审计辅助函数，逐文件 100% 覆盖率；桥接插件测试验证库的真实加载路径。`updatedInput` 已解析但仅记录日志并发出警告，直到 [input-rewrite 提案](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md)落地。

## Problem
The harness needs a hooks subsystem: users extend or gate the agent at lifecycle points the way Claude Code (CC) and Codex do. The key reframe driving this design is that **"native hooks" are not a package** — a native hook is just an ordinary Cordis plugin subscribing to the canonical lifecycle events. So the real product is a *powerful, well-typed canonical event surface*; the CC/Codex bridges (the `dsh-hooks-claude` / `dsh-hooks-codex` packages) are merely translators that map an external shell-hook protocol onto that same surface. Anything a bridge can do, a plain plugin can do directly — more powerfully (no serialization boundary, full `ctx`, typed returns).

+# Agent Note: 拦截 seam——钩子编程所面对的类型化 Decision 表面
+
+Status: implemented
+
+[English](2026-06-30-interception-seams.md) | 中文
+
+## 问题
+
+harness 需要一套钩子子系统：用户像 Claude Code（CC）和 Codex 那样在生命周期节点扩展或管控 agent（智能体）。驱动本设计的关键视角转换是：**「原生钩子」不是一个包**——原生钩子只是一个普通的 Cordis 插件，订阅规范的生命周期事件。因此真正的产品是一个*强大、类型完备的规范事件表面*；CC/Codex 桥接（`dsh-hooks-claude` / `dsh-hooks-codex` 包）只是将外部 shell 钩子协议映射到同一表面的翻译层。桥接能做的事，普通插件可以直接做——而且更强大（无序列化边界、完整 `ctx`、类型化返回值）。
+
+该表面需要为以下场景提供各自独立的契约：逐提示词策略（CC 的 `UserPromptSubmit`）、会话启动观测（CC 的 `SessionStart`）、工具执行前策略、环绕调度控制、工具执行后变换、最终结果观测，以及携带面向模型的原因的继续执行。如果把这些阶段混为一谈，插件就会获得不需要的 mutation 通道，而终结性将依赖监听器的注册顺序。[事件域语义 Agent Note](../architecture/2026-06-30-event-domain-semantics.md)提供了三域规则与类型化 Decision 惯用法；本 Agent Note 将其应用于生命周期 seam。
+
+## 决策
+
+规范表面将可变换策略、环绕调度控制与仅观测通知分离。策略 waterfall（瀑布式事件）返回小型的、seam 专属的**类型化 Decision 联合类型**；包装层返回规范化结果；通知接收不可变快照，无法影响结果。覆盖的钩子点包括 `session-start`、`prompt-submit`、`pre-tool`、`post-tool`、通过 continuation 实现的 `stop`，同时将非钩子的执行策略留作独立可组合。
+
+**Agent 事件**（`dsh-agent`）：
+- `agent/session-start(agent, source)` ——emit，在第 1 轮次之前触发一次，携带 `SessionStartSource`（`startup` 表示全新/fork 创建，`resume` 表示重新加载的持久化会话；`clear`/`compact` 保留）。纯通知，不能阻塞启动（这是有意的空白：桥接可以记录/注入，但不管控启动）。监听器通过 `agent.inject()` 注入上下文。
+- `agent/prompt-submit(agent, content, source, signal, next) → PromptDecision` ——waterfall，在轮次唯一取得所有权的排队消息追加为 `user/message` 之前触发。显式轮次 signal 位于最后的 `next` 之前；`allow` 可以重写提示词 `content` 或附加来源各自独立的 `additionalContexts[]`，而 `block` 会追加一条持久的 `prompt/blocked`，并拒绝这个零步骤轮次。
+
+**`agent/turn-continuation`** 接收并返回一个 `ContinuationDecision`。`{action:'continue', reason?}` 可携带面向模型的内容和来源，记录为同一轮次内的下一步 steering（中途引导）——与 `/goal` step-end-steer 模式互为类型化孪生。它不是 `context/message`，因此其类型不提供持久上下文元数据。
+
+### 工具流水线为每个阶段赋予一种权限
+
+每次调用遵循 `tools/pre-execute` → guards → `tools/execute` → dispatch → `tools/post-execute` → 由定义拥有的 `finalizeContent` → `tools/result`。注册表对调用方输入创建快照、实体化并冻结参数、分配一个不透明 token，并在策略开始前对可见定义的最终内容回调创建快照。嵌套调用仅携带父 token。身份始终不可变；只有 `signal` 可在环绕调度时改变。日志、UI 和工具体因此对「执行了什么」达成一致。
+
+- **`tools/pre-execute`** 是可扩展的 waterfall 门禁。其 `PreToolDecision` 允许、拒绝或询问。拒绝跳过 `tools/execute` 与核心调度。询问通过可选的审批 seam 解析：只有 `allowed-once` 继续通过 guards 和调度；拒绝、取消、通道不可用、审批服务缺失或无 agent 调用均规范化为拒绝。每个已解析的 decision 仍会到达后策略；抛出异常的监听器会成为最终的规范化失败。
+- **`ctx.tools.guard()`** 在整个 pre-execute waterfall 之后安装同步的、作用域感知的策略。guard 可以拒绝或弃权，永远不能强制允许，因此监听器顺序无法复活一个被最终不变式禁止的操作。
+- **`tools/execute`** 是用于超时、重试和指标插件的环绕调度 waterfall。包装层通过 `next()` 委托给核心调度，在此之前可以替换并恢复必需的 `exec.signal`，但不能移除它；包装层接收抛出异常或未知工具产生的、已完成规范化的规范成功／失败结果。包装层自行产生的成功结果会短路调度，并通过已解析的输出声明重新规范化。
+- **`tools/post-execute`** 是检查/变换 waterfall。其 `PostToolDecision` 接受、以反馈阻止、替换呈现内容或规范值，或附加 `additionalContexts`。替换值会重新校验并重新计算呈现；替换内容会保留程序化值，且不构成保密边界。返回的 decision 是受支持的变换通道。
+- **`ToolDefinition.finalizeContent`** 是一个可选、同步、完备且仅能处理内容的边界，在调用创建时随可见定义一起被快照。注册表将候选结果规范化并创建无损快照后，它恰好运行一次；候选结果包括绕过后续 waterfall 的 pre、around 或 post 监听器失败，以及为另一个结果字段创建快照时发现的错误。它可以替换 `content`，也可返回 `undefined` 保留原内容，但不能重写 `isError`、结构化错误身份、上下文或呈现元数据。工具在此执行自身最后一道内容不变式，而无需将策略失败转换为更弱的阻止 decision。
+- **`tools/result`** 是在所有变换、无损 JSON 实体化和外层错误边界之后的同步封闭通知。它接收相同的冻结执行身份和权威结果的不可变快照；观测者的失败按监听器隔离，无法改变或拒绝 `ToolRegistry.execute()` 返回的结果。
+
+核心调度与工具体位于规范化边界内部，因此工具、监听器、无效规范值、渲染器／投影器、非 JSON 呈现和身份形状错误均解析为 JSON 安全的 `isError` 结果，而非逃逸出轮次。post-execute 监听器因此可以检查一个抛出异常的工具；由定义拥有的最终内容不变式也会覆盖外层流水线与候选结果实体化失败；最终观测者会同时看到执行期间的规范值，以及会话日志能够持久化的确切呈现字段。[规范工具输出契约](../architecture/2026-07-20-canonical-tool-output-contract.md)定义值／投影与持久性规则。
+
+**`TurnEndReason.rejected`**（`dsh-session`）：取得所有权的提示词被 `prompt-submit` 阻止的零步骤轮次。
+
+### 三个承重的循环决策

+1. **在提示词策略之前开启轮次。** 被阻止的提示词成为零步骤的 `rejected` 轮次，保持封闭性并为 ACP（Agent Client Protocol）提供持久的终结事件。否决记录 `prompt/blocked`（含原始提示词和原因），而每个允许的 `additionalContexts` 条目都注入到已开启的轮次中。依照[一次 send 对应一个轮次的简化](../simplification/2026-07-17-one-send-one-turn.md)，每个取得所有权的 ordinary-send 条目都是其轮次中的唯一消息；启动前丢弃不会创建轮次。
+
+2. **工具执行后的 `additionalContexts` 与异步注入进入活跃批次 FIFO，并在该批次结算时追加。** `content`/`feedback` 塑造 `execute()` 返回的结果，但每项上下文都是独立的 `context/message`，而单个步骤或组合工具可以产生许多上下文。立即追加上下文会产生 `result(c1) → context → result(c2)` 的交错，或把嵌套上下文放在外层结果之前，破坏工具调用/结果邻接性。因此 `ToolRunContext.deferContext()` 会在失败路径上也收集嵌套调度上下文，`execute()` 在 `ToolExecutionResult` 上暴露有序数组，循环再把它接纳到与执行期间 `agent.inject()` 调用相同的 FIFO 中。FIFO 在批次结算时，于每个已记录结果之后追加，其中也包括被中断轮次关闭之前。被接受的外层调用将 deferred contexts 保留在 decision contexts 之前；被外层阻止时则丢弃 deferred contexts，只暴露阻止 decision 显式提供的上下文。
+
+3. **强制 `continue` 的 `reason` 通过 steering 通道入队**，使得下一步骤在循环顶部排空时将其记录为当前轮次的 steering——同一轮次内的下一*步骤* steering，而非下一*轮次*的提示词（与现有的 `hasSteering` 强制继续覆盖一致）。
+
+### 工具执行前输入重写是一个独立的一致性决策
+
+`PreToolDecision` 不能重写参数。历史和审计调用在执行前记录，UI 展示读取相同的输入，因此注册表在策略之前封存参数。有效的重写必须在身份创建之前同时更新历史、审计、展示和执行；该契约属于[输入重写提案](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md)。
+
+### 边界
+
+seam 包**不**声明 `hook/*` 会话事件（持久的钩子调用日志）；那些属于 `dsh-hook-protocol`，因为原生插件使用类型化 decision 而无需外部钩子日志。原生插件集成测试（`packages/core/agent-loop/tests/interception.spec.ts`）通过真实循环组合这些 seam，不涉及 `hook/*` 协议。压缩（compaction）（`PreCompact`/`PostCompact`）、Notification 和 Codex `PermissionRequest` 不在本决策范围内。[审批 seam](2026-07-06-approval-seam.md) 通过 `ctx.approval` 解析 `ask` decision，而终结性的单调停止由 `agent/turn-stop` 独立负责。
+
+## 曾考虑的替代方案
+
+- **将工具执行前输入重写作为本 seam 集的一部分发布**：推迟，视为越界信号；上文已阐述一致性问题（审计、历史和展示都读取执行前记录的 `tool/call.arguments`），[工具执行前输入重写提案](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md)负责该设计。
+- **将持久的 `hook/*` SessionEvents 与 seam 一起声明**：否决。原生插件使用类型化 Decision 而完全不需要钩子日志（实际示例已证明），因此持久日志属于[钩子协议库](2026-06-30-hook-protocol-lib.md)，而非 seam 表面。
+
+## 后果
+
+规范拦截表面具有统一的类型化，同时不给每个扩展相同的权力：钩子返回 decision，执行包装层做包装，终结 guard 只能拒绝，最终观测者只能观测。循环负责 session-start、prompt-submit、工具执行后上下文缓冲和 continuation；`dsh-tools` 负责身份封存与五阶段执行流水线。它们的契约记录在 [architecture.md](../../../../docs/architecture.md)、各包 README、[核心拦截 decision](../../../../docs/core-data-structures/core.md#interception-decisions) 与[工具结构](../../../../docs/core-data-structures/tools.md)中。ACP 桥接将 `rejected` 轮次映射为其 `cancelled` 编解码值，而钩子驱动的快照端到端验证可观测的桥接行为。

## Problem
The event-sourced session log already has the primitive a fork needs: create a new session with a seed event prefix, then derive model history from that seeded log exactly as replay does. That primitive is intentionally low-level: `ctx.sessions.create(id, { seed, meta })` accepts any valid seed, but ordinary live-session branching needs policy around which prefix can be copied, which metadata is stamped on the child, and how errors are classified.

The public surface stays small and discoverable: live session branching is part of `ctx.sessions`, next to `create({ seed })`, rather than a standalone service or a two-step helper pair. Persistence continues to work through existing `session/created` and `session/flush` behavior: a forked child starts life with seeded events, so existing backends persist that seed once and preserve `parentSession` / `seedLength` in the header.

+# Agent Note: SessionStore fork API
+
+Status: implemented
+
+[English](2026-06-30-session-store-fork-api.md) | 中文
+
+## 问题
+
+事件溯源的会话日志已经具备 fork 所需的原语：创建一个带有种子事件前缀的新会话，然后像回放一样从该种子日志推导模型历史。这个原语有意保持底层：`ctx.sessions.create(id, { seed, meta })` 接受任何合法种子，但常规的活跃会话分支需要围绕以下问题制定策略：哪些前缀可以被复制、子会话应打上哪些元数据、以及错误如何分类。
+
+语义上的风险在于 fork 边界。一个合法的用户可见 fork 种子必须是连续的且封闭在轮次内。如果在一个活跃轮次内部 fork，会复制一个未关闭的 `turn/start`、可能还有一个未关闭的 `step/start`，以及可能悬空的工具调用。这违反了轮次封闭性与提供方 transcript 不变式，并且会创建一段误导性的子历史——看起来子会话参与了父会话中一个尚未完成的轮次。现有的 [subagent seam](2026-06-21-subagent-capability-seam.md) 有意解决的是另一个问题：工具触发的 subagent fork 通常发生在父轮次仍然打开时，因此 `dsh-subagent-fork` 会将种子裁剪到父会话最后一个已完成轮次的前缀。通用的会话 fork 不应静默裁剪；它应当要么在请求的边界处 fork，要么拒绝请求。
+
+## 决策
+
+`dsh-session` 直接在 `ctx.sessions` 上拥有常规活跃会话 fork 的能力。不设独立的 `dsh-session-fork` 包（package），也不设 `ctx.sessionFork` 服务：该 API 没有独立的后端、事件词汇、生命周期或持久化行为，所有持久化工作都委托给现有的会话存储和持久化后端。
+
+store 暴露一个操作：
+
+```ts ignore-check
+type SessionForkSource = Session | SessionId
+
+class SessionStore extends Service {
+ fork(source: SessionForkSource, boundary?: number, childSessionId?: SessionId): Session
+}
+```
+
+`boundary` 是要复制到的源事件 `seq`（含该序号）。省略时默认为源会话当前的最后一个事件；对空源会话省略 `boundary` 则创建一个空的子会话。fork 特有的校验仅检查请求的边界是否存在且为 `turn/end`。选定的前缀随后被深拷贝到子会话的种子中。子会话继承源会话的 `cwd`，将 `parentSession` 设为源会话 id，并将 `seedLength` 设为已复制前缀的长度。省略 `childSessionId` 时，`SessionStore` 使用其现有的 id 策略生成一个。
+
+空前缀可以被 fork；任何非空边界都必须是一个安全的、已存在的、位于 `turn/end` 的序号，无论结束原因为何。类型化的错误区分源缺失、对象陈旧、子 id 重复和边界无效等情况。更广泛的日志校验与崩溃恢复仍由其现有的负责方处理。
+
+## 曾考虑的替代方案
+
+**独立的 `ctx.sessionFork` 服务。** 这是最初的实现，但评审表明它过度套用了 capability-seam 模式。代码没有可替换的后端、没有额外的事件面、没有独立的所有权生命周期，也没有超出 `ctx.sessions.create({ seed, meta })` 的持久化行为。保留独立包会迫使调用方为了在会话存储原语之上执行一层策略而去发现并安装第二个服务。
+
+**两个函数：`snapshot()` 加 `fork()`。** 这保留了一个可复用的种子/元数据计算，但唯一支持的消费方会立即创建会话。它还使接口看起来比用户实际需要的具体操作更抽象。单一的 `fork()` 加显式 `boundary` 使 API 保持直接，同时仍支持对先前时间点的 fork。
+
+**静默裁剪未关闭轮次到最后一个已完成边界。** 这对 `dsh-subagent-fork` 是正确的——委托通常在父轮次仍然打开时开始，子会话应只继承已完成的前缀。但对常规的用户/会话分支而言是错误的，因为它隐藏了请求的 fork 点实际上不是合法边界这一事实，并且静默丢弃了父轮次的尾部。
+
+## 后果
+
+公开接口保持精简且易于发现：活跃会话分支是 `ctx.sessions` 的一部分，紧邻 `create({ seed })`，而非一个独立服务或一对两步辅助函数。持久化继续通过现有的 `session/created` 和 `session/flush` 行为运作：fork 出的子会话以种子事件开始生命，因此现有后端只需持久化该种子一次，并在 header 中保存 `parentSession`／`seedLength`。
+
+v1 范围仍然排除 ACP（Agent Client Protocol） `session/fork`、对未加载的已持久化会话的 fork、面向模型的工具，以及 subagent 重构。如果未来添加 ACP 方法，应在具备协议与快照覆盖后才广播该能力；本 Agent Note 不添加任何 ACP 协议行为，因此不需要 ACP 快照。fork 子会话的回放仍由现有的[种子边界测试 Agent Note](../testing/2026-06-22-fork-child-replay-seed-boundary.md) 覆盖，而本 API 则获得专门的 `dsh-session` 单元测试加 JSONL 持久化覆盖。

## Problem
The hooks subsystem ([interception seams Agent Note](2026-06-30-interception-seams.md)) lets a plugin observe and gate the agent at lifecycle points. Claude Code and Codex both expose **SubagentStart / SubagentStop** hooks, and CC's carry the subagent's final message. The harness already emits `subagent/start` and `subagent/end` lifecycle events ([the subagent capability-seam](2026-06-21-subagent-capability-seam.md)), but their payloads were minimal (`provider`, `id`, and on end `stopReason`) — not enough for a hooks bridge to report WHAT a subagent produced without separately reaching for the live run.

+# Agent Note: Subagent 生命周期丰富化——lastAssistantMessage（仅观察）
+
+Status: implemented
+
+[English](2026-06-30-subagent-observe-enrich.md) | 中文
+
+## 问题
+
+钩子子系统（[拦截 seam Agent Note](2026-06-30-interception-seams.md)）允许插件在生命周期节点观察和拦截 agent（智能体）。Claude Code 和 Codex 都暴露了 **SubagentStart / SubagentStop** 钩子，且 CC 的钩子携带 subagent 的最终消息。harness 已经发出 `subagent/start` 和 `subagent/end` 生命周期事件（[subagent 能力 seam](2026-06-21-subagent-capability-seam.md)），但其载荷极为精简（`provider`、`id`，以及 end 时的 `stopReason`），不足以让钩子桥接层在不单独访问活跃 run 的情况下报告 subagent 产出了什么。
+
+本 Agent Note 丰富 end 载荷。它刻意限定为**仅观察**：不改变控制流，不引入 waterfall（瀑布式事件）。影响 run 的 subagent-stop 决策（续行、改变 run 的注入）属于另一个更大的重设计，不在本 Agent Note 范围内。
+
+## 决策
+
+**在 `SubagentRunEndInfo` 中添加 `lastAssistantMessage`——子 agent 的最终输出。** 在正常结束路径上，它是只读的类型化 `SubagentResult.output`，观察者无需持有 run 即可看到子 agent 产出了什么。在基础设施拒绝（不存在 `SubagentResult`）的情况下，该字段缺失，事件报告 `stopReason: 'error'`。提供方与监听方是受信任的同进程协作者，遵守借用不可变载荷的契约。
+
+两个事件仍为普通 **`emit`**。异步的 `SubagentService.start()` 将结果观察附加到就绪的提供方 run 上，发出 `subagent/start`，然后返回该 run；进程内监听方因此可以通过 `ctx.agents.get(info.id)` 访问已发布的子 agent，而远程提供方无需在本地注册表中有对应条目。提供方启动被拒绝时不发出任何事件。回调保持仅观察，且逐监听方隔离确保一个异常订阅者不会阻塞活跃 run 或饿死后续监听方。
+
+## 曾考虑的替代方案
+
+**`agentType` subagent 类别标签**（CC 的 `subagent_type` 在 harness 中的对应物），放在请求与两个生命周期载荷上。早期草案曾包含它；评审中移除，因为它是 Claude Code 的概念，不适合我们自己的 seam（此处没有任何逻辑解释它，唯一消费方是 CC 方言桥接层）。CC 桥接层改为直接为其 SubagentStart/Stop 的 `agent_type` matcher 填入 Claude Code 自身的默认值 `"general-purpose"`，因此本 Agent Note 只交付**一项**丰富化：`lastAssistantMessage`。
+
+**控制流式 `subagent/end`**：推迟；见下文。
+
+## 为何仅观察，以及推迟了什么
+
+控制流式 `subagent/end`（一个被 await 的 waterfall，返回停止/继续决策，与其他拦截 seam 一致）需要：将 `subagent/end` 从 emit 改为 waterfall、重构 `SubagentService.start` 使其在结算前 await 监听方、在进程内提供方中实现 `resume` 能力以便「继续」能真正重新运行子 agent。这属于[能力 seam Agent Note](2026-06-21-subagent-capability-seam.md) 已推迟的后台/steering（中途引导）subagent 重设计（同一个重设计还将统一 subagent 与 bash 之间的长时间运行工具处理）。本 Agent Note 交付钩子桥接层当前所需的仅观察丰富化；`FIXME(subagent-continuation)` / `TODO` 锚点标记了控制流版本在重设计发生时的落点。
+
+## 后果
+
+钩子桥接层（或原生插件）现在可以通过订阅既有 emit 将子 agent 的 `lastAssistantMessage` 转发给 SubagentStop 处理器，无需新的控制流接口。词汇新增记录在 [docs/core-data-structures/subagent.md](../../../../docs/core-data-structures/subagent.md)（事件行文部分）与两个 subagent README 中；catalog 已重新生成。生产行为无变化——事件触发方式与之前完全一致，end 载荷上多了一个可选字段——因此无需更新快照或 e2e 测试。

## Problem
The harness can delegate ONE task to ONE child (`dsh-tool-subagent`), but work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — forces the model to orchestrate turn by turn: every intermediate result lands in the parent context, the plan lives nowhere durable, and coordination costs a model round-trip per step. Claude Code ships this capability as [dynamic workflows](https://code.claude.com/docs/en/workflows): the model writes a JavaScript orchestration script, a runtime executes it, and the script — not the conversation — holds the loop, the branching, and the intermediate results.

+# Agent Note: 动态工作流——脚本驱动的多 agent 编排 seam
+
+Status: implemented
+
+[English](2026-07-05-dynamic-workflows.md) | 中文
+
+## 问题
+
+harness 可以将一个任务委派给一个子 agent（`dsh-tool-subagent`），但需要扇出到多个独立部分的工作——跨多文件审计、迁移、多角度调研、对抗式验证——迫使模型逐轮次编排：每个中间结果都落入父上下文，计划无处持久存储，每一步的协调都要消耗一次模型往返。Claude Code 以[动态工作流](https://code.claude.com/docs/en/workflows)的形式提供了这一能力：模型编写一段 JavaScript 编排脚本，运行时执行它，由脚本（而非对话）持有循环、分支和中间结果。
+
+## 决策
+
+在 `packages/workflow/` 下以 bash seam 的形态（接口／实现／消费方）提供一组工作流能力，以及它在 subagent seam 上所需的结构化输出基础。
+
+### 脚本契约（兼容 Claude Code）
+
+一次工作流调用包含 JSON `meta`（`name`、`description`，以及可选的 `whenToUse`/`phases`）和一段支持顶层 `await` 并返回 JSON 值的 JavaScript `script` 正文。元数据作为数据校验，从不被执行。正文接收 `agent(prompt, options)`、`parallel(thunks)`、`pipeline(items, ...stages)`、`phase(title)`、`log(message)` 和 `args`。流水线各阶段接收 `(prev, item, index)`，阶段之间无屏障；失败的子 agent 和普通阶段错误将受影响的 item 解析为 `null` 并跳过其剩余阶段。Claude Code 的确定性限制通过日志化延迟处理，因此兼容的脚本正文在将 meta 头移入参数后可以使用时钟和随机数。
+
+与 CC 有一处刻意的严格性差异：钩子误用——未知或延迟的选项（`effort`/`isolation`/`agentType`）、格式错误的参数、超出支持子集的 schema、触发上限、seam 启动失败——会抛出带 `fatal: true` 的 `WorkflowError`，组合器会重新抛出 fatal 错误而非将 item 置为 null。如果不这样做，一个拼错的选项会悄然变成一个与子 agent 失败无法区分的 `null`——这正是本仓库禁止的「被接受后被忽略」的失败模式。另有一处新增：工具的 `args` 参数是一个 JSON 对象（裸列表被包装为一个字段），使协议格式（wire format）保持诚实。
+
+### seam（dsh-workflow）
+
+`ctx.workflows` 是 bash 形态的抽象 `WorkflowService`——每个上下文一个引擎，无命名提供方注册表（引擎是部署级替换，不是共存者）。`start(request)` 对无法启动的脚本同步抛出；返回的 `WorkflowRun` 的 `result` 永不 reject（失败解析为 `stopReason: 'error' | 'cancelled'`）。`workflow/*` 事件是仅观察的 emit，携带数据快照（id + meta；`workflow/end` 省略 result 值），按监听器隔离，与 `subagent/start`/`subagent/end` 对称——控制权留在 run 的持有者手中。词汇详情见 [core-data-structures/workflow.md](../../../../docs/core-data-structures/workflow.md)。
+
+### 引擎（dsh-workflow-workerthread）：每次运行一个 worker 线程
+
+**信任前提**：工作流脚本与模型的 bash 访问具有相同的信任级别。引擎容纳有缺陷的脚本，并保证结果已 settled、值为 JSON 安全、取消后完全停稳；它不防御恶意代码。vm 上下文和 worker 线程不是安全边界：脚本可以逃逸到具有进程级权限的 Node API。沙箱化需要在此 seam 背后使用独立进程或 isolated-vm 引擎。
+
+**为何选择 `node:worker_threads`**：每次运行获得一个非池化的 worker。vm 上下文限制了文档化的脚本表面，而消息端口 RPC 将 `agent()` 桥接到宿主侧的子循环。worker 防止脚本的同步工作阻塞宿主，提供序列化边界，并允许取消后强制终止。`isolated-vm` 因其维护状态和部署要求被否决。
+
+宿主在发布前校验元数据并解析正文。私有枚举键 payload 映射定义协议格式；待启动记录、已发布子记录、单一取消信号、worker 死亡回收、结果优先级与 dispose 完全停稳，在此协议上保持 subagent run 契约。这些竞态算法归[agent 作用域运行时设计 Agent Note](../architecture/2026-07-12-agent-scope-runtime-design.md#workflow-children-are-pending-starts-or-published-records)所有。
+
+引擎暴露一条进程内 `MessageChannel` 测试路径，因为主进程 V8 覆盖率无法观测 worker 执行。
+
+**Meta 是数据**：经 schema 校验的 `meta` 字段以 JSON 形式到达 seam，仅做形状校验。宿主从不执行元数据字面量，否则脚本控制的访问器可以在 worker 隔离之外运行。
+
+**值边界**：`materializeFromRealm` 复制出站值，并拒绝函数、symbol、嵌套 `undefined`、异域原型、循环引用、稀疏数组和非有限数字。数据属性复制使 `"__proto__"` 安全；getter 正常读取，抛出异常的 getter 会大声失败。`args` 通过 `workerData` 传入，暴露前再次克隆。realm 函数被调用而非复制，抛出的值使用全量渲染器，因此 `result` 不会 reject。钩子错误是宿主 realm 的 `WorkflowError`，脚本应基于 `name` 或 `code` 分支而非 `instanceof Error`，如引擎 README 所述。并发、total-agent、item、超时和宽限限制均为经校验的配置。
+
+### 消费方（dsh-tool-workflow）
+
+一个 `workflow` 工具，镜像 `dsh-tool-subagent` 的同步形态：启动、await、`try/finally` dispose、abort 桥接 `exec.signal`、非 `completed` → `isError`。渲染意图：一张以调用的 `meta.name` 参数为标题的 `generic` 卡片（展示是参数的纯函数）。工具描述即面向模型的编写规范。使用策略以工具自身的 `tool:<toolName>` 提示词段落随工具发布（显式请求才使用的引导——工具引导存在于工具插件中，从不在部署 persona 中）；harness 没有 ultracode 风格的 effort 门控。
+
+### 基础：subagent seam 上的结构化输出
+
+`SubagentStartRequest.outputSchema` 由 `dsh-subagent-inprocess` 为两个进程内后端实现。每个结构化子 agent 在 `child.ctx` 上获得自己的作用域捕获工具、指令和强制注册；并发子 agent 可以使用不同的 schema 而不共享可变策略，dispose 子 agent 时移除整个附件。
+
+输出 schema 使一次 schema 有效的已提交捕获成为子 agent 成功完成的必要条件。作用域运行时呈现捕获工具和指令，仅提交成功的最终结果（包括 SDK 调用时外层 `run_code` 的结果），在捕获变为 pending 后拒绝后续副作用，并在提交后不再进行模型步骤即停止子 agent。校验失败仍是可重试的工具错误；没有已提交捕获的正常完成以错误结算。
+
+`ObjectJsonSchema` 是 `dsh-tools` 统一且可强制执行的原始 JSON Schema 子集所提供的对象根消费方视图；不支持的关键字会大声失败，因为该协议数据会逐字成为捕获工具的 parameters。[统一 JSON 值 schema Agent Note](../architecture/2026-07-20-unified-json-value-schema-dsl.md)定义词汇与校验语义，[agent 作用域运行时设计 Agent Note](../architecture/2026-07-12-agent-scope-runtime-design.md#structured-output-commits-only-authoritative-outcomes)则定义组装、提交、守卫和终止停止算法。
+
+## 测试
+
+worker 侧逻辑通过进程内 `MessageChannel` 运行，使 V8 覆盖率能够度量它。单元测试覆盖脚本辅助函数、fatal 与 nullable 失败、JSON 边界、上限、取消、子 agent 所有权和通过真实循环的结构化输出。built-bin 冒烟测试在纯 Node 下运行单独打包的 `lib/worker.cjs`，带密钥的 e2e 驱动真实子 agent，面向模型的工作流行为通过其所属示例进行快照覆盖。
+
+## 延迟（本轮明确的非目标）
+
+- **后台收集**（启动工具 → run id → 完成通知 → 收集），与 bash/subagent 后台统一一起设计。
+- **日志化 + 恢复**（`resumeFromRunId`、缓存的 agent() 前缀）：实现它会以脚本契约收紧的形式重新引入 CC 的确定性禁令（脚本目前可以读取时钟）。
+- **保存/打包的工作流**（`.deepseek/workflows/` 注册表、斜杠命令界面）和**脚本持久化到运行目录**（工具调用事件已经持久记录了脚本）。
+- **嵌套 `workflow()`**、**token `budget`**，以及 `effort`/`isolation`/`agentType` agent 选项（每个都以命名延迟的消息大声拒绝）。
+- **整体运行的挂钟超时**：取消总能释放调用方（result 在宽限期内 settle），因此总运行时间上限是后台重设计的策略旋钮，不是此处的正确性需求。
+- **超越 worker 线程的引擎加固**：在同一 seam 背后使用 isolated-vm 或独立进程引擎（真正的沙箱化；内存限制）。
+- **面向人类界面的进度 UI**（基于 `workflow/*` 事件的 `/workflows` 风格视图）；事件已为此而存在。
+- **ACP 后端结构化输出**和 **`toolFilter`**（两者仍以能力标志 `false` 门控）。
+
+## 曾考虑的替代方案
+
+- **宿主侧的恶意值防护**（无 trap 代理拒绝、从不调用访问器的描述符遍历、realm 侧预渲染抛出值、realm 构建的 promise/array/error 克隆加结构化 fatal 识别）：否决。每项防御针对的都是信任前提所接受的作者，而线程的序列化边界已经从构造上使跨 realm 值全量化。
+- **进程内 `node:vm` 执行**：机械上最简——无 RPC、无线程——但 `start()` 会在脚本的初始同步切片期间阻塞调用方，第一个 await 之后的同步自旋无法在进程内终止（vm `timeout` 仅覆盖第一个切片），且 `dispose()` 只能在宿主循环上放弃一个未 settle 的脚本。worker 线程引擎保持相同的 vm 上下文脚本表面，同时解除宿主阻塞并使终止成为现实。
+- **后台执行作为默认**（CC 的形态）：延迟。前台同步与 `dsh-tool-subagent` 的当前形态一致，后台语义应在 bash、subagent 和工作流之间统一设计一次，而非逐工具设计。
+- **工作流层为 `agent({schema})` 做 JSON 解析**：在一个消费方重复 seam 关注点，而 seam 的能力标志仍不诚实地为 `false`。
+- **Meta 嵌入脚本中作为 `export const meta = {...}`**（CC 的确切格式）：保持脚本自包含且 CC 脚本可直接使用，但获取 meta 需要在宿主上执行模型编写的文本。即使一个空的限时 vm 上下文也无法约束脚本控制的 getter（当宿主读取结果对象时）。JSON 参数消除了扫描器、执行和宿主自旋漏洞；代价是 CC 脚本的 meta 头必须移入参数（正文保持可直接使用）。
+- **`ValueSchemaSpec` 作为 `outputSchema` 协议类型**：面向作者的形式如今具有等价词汇，但工作流提供的是来自其他 realm 的原始 JSON Schema 数据；将这类运行时数据假装成可信的作者声明，会跳过原始 schema 断言边界。
+- **schema 对象库（zod 或本仓库的 schemastery）用于结构化输出子集**：schema 是协议数据——纯 JSON，跨越 `agent({schema})` 中的 vm realm 边界并逐字落入强制工具的 parameters——正是活 schema 对象无法存在的位置；在运行时消费原始 JSON Schema 需要在其上加一个第三方转换器（zod core 只输出 JSON Schema，不能反向），且会在 schemastery 的配置角色旁边放置第二种 schema 语言。
+- **ajv 用于值校验**：它校验完整 JSON Schema，因此子集门控——模块的真正要点，因为每个被接受的关键字都必须是 harness 强制执行的——无论如何仍需手写；它通过 `new Function` 编译校验器；且它将成为 dsh-tools 的第一个运行时依赖，仅为替换约 70 行的值遍历器，而路径限定的、报告每一处违规的错误报告无论如何都是自定义的。
+- **提供方 JSON 模式代替捕获工具**：它保证有效 JSON，不保证 schema 一致性，且它与工具调用的交互不明确。捕获工具保留了轮次内的校验重试。提供方侧的严格工具 schema 后续可以在不改变本设计的情况下收窄接受的子集。
+
+## 后果
+
+扇出计划现在存在于可重运行的脚本中，`outputSchema` 提供权威的结构化子 agent 结果。每次运行付出 worker 启动和消息端口 RPC 成本，但宿主启动保持非阻塞，取消可以终止 worker，序列化强制执行值边界。worker 线程不是安全边界。无效选项快速失败而非退化为 Claude Code 的 `null`；消费方通过 run handle 保持控制权，观察者仅接收快照。

Agent products have converged on a skill pattern: keep the request prompt small by listing only available instruction bundles, then load the full body when the model decides a task matches. Codex, Claude Code, OpenCode, and Kimi Code differ in details, but all separate discovery metadata from complete instructions so a workspace can carry reusable behavior without paying the full prompt cost on every turn.

+# Agent Note: Skill 系统——面向 agent 的渐进式指令披露
+
+Status: implemented
+
+[English](2026-07-05-skill-system.md) | 中文
+
+## 问题
+
+Agent（智能体）产品已趋同于一种 skill（技能）模式：保持请求提示词精简，仅列出可用的指令包，当模型判定某任务匹配时再加载完整正文。Codex、Claude Code、OpenCode 与 Kimi Code 在细节上各有不同，但都将发现元数据与完整指令分离，使工作区能承载可复用的行为而无需在每个轮次支付全量提示词开销。
+
+DeepSeek Harness 使用同一原语，使项目特定的评审、插件编写和工具使用指南存放在工作区或用户的 agent 配置旁，而非硬编码到 agent loop（智能体循环）中。
+
+## 决策
+
+`@deepseek-ai/dsh-skill` 是纯提供方注册表（`ctx.skills`），`@deepseek-ai/dsh-skill-local` 是随附的本地文件系统提供方，`@deepseek-ai/dsh-tool-skill` 负责会话前缀目录与面向模型的 loader 工具。`dsh-agent-spine-demo` 默认加载注册表、本地提供方和消费方，使 TUI、headless 与 ACP（Agent Client Protocol）应用获得相同行为，同时嵌入式或远程提供方可在不修改注册表或消费方的前提下贡献 skill。其 `skills` 配置将 `registry`、`local` 和 `tool` 分支分别转发给对应的所有者。
+
+提供方插件在 `apply()` 期间同步注册。提供方成员资格是由直接 effect 持有的状态：注册与 dispose（资源释放）同步地使已完成的目录失效，发现操作按需读取当前提供方映射而非监听注册表变更事件。提供方目录从等待的 `list()` 调用返回排序后的候选项，远程提供方在此过程中执行初始化、认证和发现，同时遵守查找的 abort 信号。注册表校验每个候选项，按排名、提供方注册顺序和提供方内部顺序以先到先得方式解决同名 skill 冲突，然后按 skill 名称排序摘要以保证消费方获得确定性结果。它仅缓存已完成的目录快照，并在发现过程中提供方/运行时修订版本发生变化时重试，因此卸载操作不会将一个陈旧且不可解析的 skill 冻结到会话前缀中。运行时 `ctx.skills.register(...)` 仍作为嵌入式进程内 skill 的便捷方式保留，使用 project 优先于 user 的优先级；`runtime` 保留为注册表拥有的提供方名称。
+
+本地提供方按先到先得的排名顺序扫描 cwd 敏感的项目根目录、自定义根目录和用户根目录：项目 `.dsh`、项目 `.agents`、`customSkillDirs`、用户 `.dsh`，然后是用户 `.agents`。用户 `.dsh/skills` 扫描跳过 `.system`，以免系统拥有的目录被当作普通用户内容处理。DeepSeek Harness 不随附内置系统 skill；嵌入式或远程提供方在配置后提供额外 skill。
+
+每个 skill 是 `<name>/SKILL.md` 或带 YAML frontmatter 的 `<name>.md`。`name` 和 `description` 为必填；`whenToUse`、`disableModelInvocation` 和 `metadata` 为可选。名称采用 kebab-case。YAML frontmatter 使用 `yaml` 包（package）解析，而非 `js-yaml` 或手写解析器：`yaml` 是本包有限 frontmatter 需求已声明的现代解析器，窄解析器要么拒绝用户预期可用的合法 YAML，要么膨胀为一个未经评审的 YAML 子集。
+
+本地 skill 的文件系统 I/O 在加载了文件系统服务时通过 `ctx.fs` 进行：项目根目录查找使用 `resolve` 和 `stat` 探测 `.git`，根目录发现使用 `listDir`，skill 读取使用 `readText`。Node 文件系统作为后备，供在不挂载 fs seam 的最小上下文中加载 `dsh-skill-local` 时使用。缺失的根目录、不可读或格式错误的 skill 文件、以及提供方 `list()` 的瞬态失败均降级为警告并跳过，使一个坏源不会导致所有 agent 请求失败；格式错误的候选项仍然快速失败，因为它们违反了提供方契约。
+
+`dsh-tool-skill` 通过 [`agent/session-prefix`](2026-07-07-session-prefix.md) 贡献一个 user-role `<system-reminder>` 目录。该目录仅包含排序后的 skill 名称与描述；不包含正文、路径、来源、提供方和路由提示。描述经过空白规范化、XML 转义，并受 `catalogDescriptionMaxLength` 上限约束，其默认值为 `500`，最小值为 `3`。session-prefix seam 将仅用于请求的目录按 loop 实例冻结，并记录在请求头中，在不将其加入持久化历史的前提下保持可重建性。完整的 skill 正文从不包含在目录中。
+
+`skill({ name })` 工具为当前 agent cwd 加载一个完整 skill，返回包含 `<skill_content name="...">`、`<skill_resources>` 和 `<skill_instructions>` 的工具结果。`resourceBase` 提供一个目录、URL 或不透明的提供方管理的基路径，用于显式引用的脚本、参考资料和资产；资源仅按需加载，不进行目录枚举。无法解析的名称报告该 skill 未知或不再可用；无效名称和标记了 `disableModelInvocation` 的 skill 保留不同的工具错误。工具结果是面向模型的可见披露路径。
+
+数据结构与目录/工具契约记录在 [skills.md](../../../../docs/core-data-structures/skills.md) 中，服务签名见生成的[服务目录](../../../../docs/cordis-catalog/services.md)。
+
+## 曾考虑的替代方案
+
+**将完整 skill 正文注入每条系统提示词。** 否决，因为这破坏了渐进式披露，使每个请求都为可能不适用的指令付出代价。
+
+**仅以斜杠命令暴露 skill。** 否决，因为模型主动加载是核心能力；面向人类的命令广播不改变发现机制。
+
+**将本地文件系统扫描直接放入 `ctx.skills`。** 否决，因为编码 agent、Web agent 和未来的插件生态需要不同的 skill 来源。提供方注册表与 subagent seam 镜像：注册表拥有冲突解决和消费方，实现拥有加载。
+
+**使用系统提示词段落。** 否决，因为渲染后的系统提示词是单一字符串，而目录是一条具有仅请求生命周期要求的 user-role `<system-reminder>` 消息。[`agent/session-prefix`](2026-07-07-session-prefix.md) 是选定的机制：它将目录置于派生历史之前，并将组合后的消息记录在请求头中。
+
+**在 `~/.dsh/skills/.system` 下物化内置 DSH 编写 skill。** 否决，因为打包的 skill 不应在启动时写入用户主目录，嵌入式或远程提供方在配置后提供 skill。
+
+**递归发现嵌套的 `**/SKILL.md`。** 否决。扁平文件和一级目录包覆盖了配置的根目录，同时使重复处理和目录顺序易于推理。
+
+**手写 frontmatter 解析器。** 否决，因为已接受的 schema 包含一个开放的 `metadata` 对象。窄解析器要么拒绝用户预期可用的合法 YAML，要么膨胀为一个未经评审的 YAML 子集。
+
+## 后果
+
+agent-core 主干包含一个 session-prefix 贡献者、一个本地提供方和一个面向模型的工具。Skill 发现是 cwd 敏感的，因此以不同会话 cwd 值创建 agent 的调用方可以按设计观察到不同的项目 skill 覆盖。
+
+目录对于固定的根目录集合和运行时注册修订版本是确定性的，但不监视磁盘变化；发现结果被缓存，直到运行时注册使缓存失效或进程重启。
+
+## 延后
+
+Fork 的 skill 上下文（`context: fork`）、参数声明与提示（`arguments` 和 `argument-hint`）、以及逐 skill 的工具约束（`allowed-tools` 和 `disallowed-tools`）不在已交付的契约范围内。注册表、本地提供方和面向模型的工具不解析、不广播、也不执行这些字段，`user-invocable` frontmatter 字段同样不会被解析。直接用户调用本身则作为消费方层面的能力交付：TUI 前门基于注册表现有的 `list()` 与 `get()` 方法提供手动 `/skill:<name>` 命令，无需变更注册表、提供方或工具契约——见 [TUI skill 斜杠命令](2026-07-21-tui-skill-slash-command.md)。

Answerers are `approval/request` waterfall listeners. Zero listeners fall through to `unavailable`; a recognizing listener occupies the first-wins decision slot, while an unrecognized agent must delegate with `next()`. Listeners dispose with their fibers, so an unloaded channel fails closed. Because sibling registration order is not deterministic, a deployment composes one terminal answerer and reserves `prepend` for decide-or-delegate gates.

- **The generic user-interaction seam (`ctx.userInteraction`)** — rejected as the approval mechanism: the two share a skeleton (route by agent, block for a human, handle absence), but approval's contract is narrower in every dimension that matters: a closed outcome vocabulary instead of free text, a protocol-native prompt attached to a tool call instead of a generic form, mandatory fail-closed absence, and audit events. Approval therefore does not ride the shipped `packages/ui/user-interaction` / `ask_user_question` elicitation path — an elicitation form is not a permission prompt, and a free-text answer is not a closed outcome; sharing provider plumbing stays open if the two ever converge.
- **Static optional injection in `dsh-tools`** — rejected: the vendored cordis `Inject` type has no optional flag — the object form maps service names to intercept config, and a declared inject gates the fiber. `ctx.get('approval')` is the documented opportunistic-consumption pattern (the `tool-bash` owner-token lookup, the loop's persistence probe), reads presence per call, and degrades correctly across HMR without extra machinery.
- **The capability-seam three-package split** — rejected: interface/implementation/consumer fits a seam whose implementation is swappable (bash-local vs bash-sandbox).

Costs and accepted limits:
- **Two decide-eager answerers race for the slot.** Sibling-plugin listener order is not deterministic, so the seam cannot referee competing terminal answerers — mitigated by convention (one terminal answerer per deployment; `prepend` only for decide-or-delegate gates) rather than a priority mechanism the event bus does not have.
- **Production exercise rests on one composition.** `ask` has two producer families — the hook bridges through `tools/pre-execute`, and sandbox escalation through its own gate — with the wire recorded in the sandbox example's snapshot suite, so the seam's real-world coverage is that one composition until more deployments compose it.

- **What happens when the user dismisses the prompt, or the turn aborts mid-ask?** Dismissal maps to `cancelled` with its own deny text.

+# Agent Note: 审批 seam——基于 waterfall（瀑布式事件）应答者的一次性权限决策
+
+Status: implemented
+
+[English](2026-07-06-approval-seam.md) | 中文
+
+## 问题
+
+两个调用方需要同一个封闭决策——「这个具体操作可以继续吗？」：`tools/pre-execute` 的 `ask` 决策（包括 Claude-Code 钩子桥的 `permissionDecision: ask`）以及[沙箱 Agent Note](2026-07-06-sandbox.md) 中拒绝后的一次性升级重试。一个共享的 seam 使它们无需各自发明独立的结果词汇、通道路由、取消机制和审计轨迹，同时保证没有应答者的部署永远不会批准一个无法应答的请求。应答者可以是交互式宿主，也可以是自动化控制器。
+
+路由问题的核心是归属：权限请求必须到达拥有发起请求的 agent（智能体）的通道，对无人拥有的 agent 失败关闭，并且不侵入没有组合应答者的部署。
+
+## 决策
+
+一个包 `dsh-user-approval`（`packages/ui/user-approval`），拥有词汇表和 `ctx.approval` 服务——即机制。策略——谁来应答、某个会话是否需要被询问——不在其中：应答者是 `approval/request` waterfall 监听器，由拥有通道的插件注册（ACP（Agent Client Protocol）桥、宿主适配器、测试脚本），而每会话的策略层可以在任何通道介入之前做出决定。消费方（`dsh-tools` 的 ask 路由和沙箱升级门禁）将问题解析为一个封闭结果，并从中派生各自的工具结果。刻意设计为一个包，而非能力 seam 的三包拆分（见「替代方案」）。
+
+### 部署如何使用它
+
+一条 `cordis.yml` 条目挂载该 seam。不加载它就是失败关闭的退出方式：消费方在没有注册任何审批代码的情况下拒绝无法应答的请求。
+
+```yaml
+- id: approval
+ name: '@deepseek-ai/dsh-user-approval'
+ # config:
+ # policy: never # deployment default for sessions without an override; 'ask' when omitted
+```
+
+仅有这条条目只提供机制，不提供通道：没有组合应答者时，每次 ask 都解析为 `unavailable`，发起请求的工具调用被拒绝——失败关闭无需配置。组合 ACP 应用（`@deepseek-ai/dsh-acp-demo`，如 [acp-agent 示例的默认树](../../../../examples/acp-agent/README.md)）即可闭环：其[仅面向自动化的桥接层](../simplification/2026-07-23-acp-automation-only-protocol.md)注册一个应答者，向拥有该会话的客户端发送 `session/request_permission`，携带精确的工具调用 id 和一次性 allow/reject 选项。`policy: never` 是无人值守姿态：每次 ask 确定性地自动拒绝，并在系统提示词中声明。`policy` 在插件加载时对照封闭列表校验；非法值直接抛异常。
+
+组合部署的可观测行为：`allowed-once` 仅允许该次调用继续；拒绝、关闭和通道缺失以三种不同原因拒绝，模型可以区分；轮次内成功的请求会在发起请求的 agent 的会话日志上落一对持久的 `approval/asked`/`approval/decided` 事件；授权不会在发起请求的调用结束后继续存在。空闲时的请求或审计追加失败会拒绝，而不会返回未经审计的决策。
+
+以下是该组合下的一次 ask，取自沙箱示例录制的 `escalation-approved` 场景——模型请求沙箱升级，门禁发起 ask，自动化客户端选择 Allow once：
+
+```
+tool/call bash {"command": "printf 'escalated\n' > escalated.txt && cat escalated.txt",
+ "sandbox_permissions": "workspace-write",
+ "justification": "the user asked to write escalated.txt in the workspace"}
+approval/asked {"toolName": "bash", "callId": "call_00_…",
+ "reason": "escalate sandbox to workspace-write: the user asked to write escalated.txt in the workspace"}
+ → session/request_permission {"toolCall": {"toolCallId": "call_00_…"},
+ "options": [{"optionId": "allow-once", "name": "Allow once", "kind": "allow_once"},
+ {"optionId": "reject-once", "name": "Reject", "kind": "reject_once"}]}
+ ← the client selects "Allow once"
+approval/decided {"outcome": "allowed-once"}
+tool/result "escalated" — this one call ran under the wider mode; the grant died with it
+```
+
+`escalation-rejected` 孪生场景以 `{"outcome": "rejected"}` 结束：不执行任何操作，模型的结果携带发起方的逐字失败关闭文本（`the user rejected escalating this command to "workspace-write"`）。钩子的 `permissionDecision: ask` 走完全相同的协议；只有发起方和拒绝文本不同（§ dsh-tools 中的 Ask 路由）。没有应答者时，同一请求直接结算为 `unavailable`。
+
+### 设计细节
+
+#### seam：机制与策略分离
+
+经过校验并成功追加 `approval/asked` 后，服务将 `approval/request` waterfall 解析为 `allowed-once`、`rejected`、`cancelled` 或 `unavailable`。服务借用只读的请求标识和 signal，将中止视为 `cancelled`，把应答者失败和无效返回容纳为 `unavailable`，丢弃迟到的应答，并追加配对的 `approval/decided` 事件。提交前的审计失败会拒绝；追加后的观察者失败无法撤销权威事件。`allowed-once` 仅授权所询问的操作，而 `request()` 会拒绝打开轮次之外的调用，以保证审计对留在持久提交边界内。
+
+应答者是 `approval/request` waterfall 监听器。零监听器会一路委派至 `unavailable`；识别该 agent 的监听器占用先到先得的决策槽，而不识别的监听器必须调用 `next()` 委派。监听器随其 fiber dispose，因此卸载通道会失败关闭。由于兄弟插件的注册顺序不确定，部署应组合一个终端应答者，并保留 `prepend` 给「决策或委派」门禁。
+
+`ApprovalRequest` 携带发起请求的 `agent`、`toolName`、可选的精确 `callId`、人类可读的 `reason` 和可选的 `signal`。它使用 `CallId` brand 而不导入依赖本 seam 的 `dsh-tools`。通道适配器可按 `callId` 关联任何更丰富的调用状态；审批请求本身不重复携带工具参数。
+
+#### dsh-tools 中的 Ask 路由
+
+`ToolRegistry.execute()` 在派发前解析 `ask`：`allowed-once` 继续执行，而拒绝、取消和通道不可用产生三种不同的拒绝原因。机会性消费 `ctx.get('approval')`，让缺失或未挂载的服务失败关闭而不阻塞注册表 fiber。无 agent 的执行同样失败关闭，因为它既没有审计会话，也没有通道所有者。
+
+#### 每会话策略层
+
+seam 还拥有[沙箱 Agent Note](2026-07-06-sandbox.md) 所描述的会话级 `'ask' | 'never'` 策略。生效策略由日志中记录的切换在部署默认值之上折叠而成。`'never'` 会在任何应答者运行之前，于 `request()` 内部解析为 `rejected`；`'ask'` 则派发请求，否则一路委派至 `unavailable`。提示词仅声明确定性的 `'never'`，切换叙述会被合并，每个请求仍记录审计对。
+
+#### ACP 应答者
+
+ACP 桥只应答其会话映射所拥有的精确 agent 对象。它携带既有 `callId` 发送 `session/request_permission`，声明一次性的 allow/reject 选项，单独映射取消，并且绝不批准未知选项。外部或无调用标识的请求会委派；客户端 RPC 失败变为 `unavailable`。钩子和 `tools/pre-execute` 决定一次调用是否需要询问。该通道是自动化客户端与其 agent 之间的机器策略，不是 ACP 展示层。
+
+应答者通过[仅面向自动化的 ACP Agent Note](../simplification/2026-07-23-acp-automation-only-protocol.md)描述的桥精确 agent 归属检查进行路由，保留了[多会话 Agent Note](2026-06-14-acp-multi-session.md) 要求的每会话权限归属。
+
+#### 审计，以及模型看到什么
+
+`approval/asked` 和 `approval/decided` 是持久的仅日志事件；模型只看到从结果派生出的普通工具结果。成功完成时，每个 `asked` 都提交一个 `decided`，包括取消和被容纳的应答者失败。空闲时的请求不追加任何事件；提交前失败会拒绝，而第二次追加失败可能留下一个已经提交但未匹配的 `asked`。
+
+#### 实体与依赖
+
+`dsh-user-approval` 依赖 Cordis，以及会话、agent 和带 brand 的调用契约；`dsh-tools` 与 `dsh-acp` 消费它。沙箱执行器保持独立，因为升级请求归 `dsh-tool-bash` 所有。固定的派发与审计服务仍是一个包；可替换的应答者留在各自的通道所有者中。静态能力授权和 `subagent-acp` 子侧权限应答仍是独立关注点。
+
+### 测试
+
+单元测试固定结果、先到先得的委派、错误容纳、取消、作用域路由、审计配对、不可绕过的 `'never'` 策略、工具拒绝原因，以及通过真实脚本化桥实现的 ACP 归属/结果映射。
+
+快照记录通过 `session/request_permission` 批准和拒绝沙箱升级，以及 `'never'` 提示词与策略切换通知。没有脚本化应答的权限提示会取消并失败关闭。
+
+## 延后
+
+- **`allow_always` 授权存储**：兑现持久授权意味着设计存储、作用域标识（调用？路径？前缀？会话？时间窗口？）和撤销；在设计完成之前，只展示一次性选项（[沙箱 Agent Note](2026-07-06-sandbox.md) § Escalation 记录了开放的作用域问题）。
+- **通过组合应答者录制由钩子驱动的 `ask`**：权限协议格式已通过沙箱示例的升级分支录制。钩子矩阵中的 `hook-cc-pretool-ask` 固定无 ApprovalService 时的后备拒绝，而钩子生产者与应答者的组合仍留在单元测试层。
+- **将子 agent 的审批路由到父会话**：`subagent-acp` 的子侧自动应答自己的权限请求；将其委派给父控制器是独立的设计。
+
+## 曾考虑的替代方案
+
+- **单一注册提供方而非 waterfall 监听器**：否决。`registerProvider()` 接口迫使所有组合问题——允许列表预过滤、外部钩子决策者、脚本化测试应答、人类前面的策略门禁——都塞进一个提供方实现。waterfall 从运行时已有的机制中获得组合能力、缺失时失败关闭和 HMR（热模块替换） dispose（资源释放）；seam 的 JSDoc 以约定固定单决策槽语义，而非发明一个提供方注册表。
+- **在 ACP 桥中内联 `tools/pre-execute` 权限门禁**：否决。对桥拥有的每次调用都弹出提示，会将请求策略硬编码进传输层，无法服务第二个发起方（沙箱升级发生在执行开始之后，没有 pre-execute 时刻），且钩子产生的 `ask` 决策没有共享机制。
+- **通用用户交互 seam（`ctx.userInteraction`）**：否决作为审批机制。二者骨架相似（按 agent 路由、阻塞等待人类、处理缺失），但审批的契约在每个关键维度上都更窄：封闭的结果词汇而非自由文本、附着在工具调用上的协议原生提示而非通用表单、强制的缺失时失败关闭、以及审计事件。因此审批不走已交付的 `packages/ui/user-interaction` / `ask_user_question` 引出路径——引出表单不是权限提示，自由文本应答不是封闭结果；如果二者将来趋同，共享提供方管道仍然开放。
+- **`dsh-tools` 中的静态可选注入**：否决。vendor 的 Cordis `Inject` 类型没有 optional 标志——对象形式将服务名映射到拦截配置，声明的 inject 会阻塞 fiber。`ctx.get('approval')` 是文档化的机会性消费模式（`tool-bash` 的 owner-token 查找、loop 的持久化探测），按调用读取存在性，跨 HMR 正确降级，无需额外机制。
+- **能力 seam 的三包拆分**：否决。接口/实现/消费方适合实现可替换的 seam（bash-local vs bash-sandbox）。此处服务体是固定机制，可变部分是留在各自通道拥有者插件中的监听器——拆分只会制造一个空的实现包（「不要预防性拆分」）。
+- **现在就提供 `allow_always`**：否决。协议能表达它，但兑现它意味着设计授权存储、作用域标识和撤销（§ 延后）。展示 harness 无法兑现的选项只会制造注定失败的授权。
+
+## 后果
+
+实现后的契约由「测试」一节所列套件固定：
+
+- `allowed-once` 派发一次操作；其他所有结果都以不同原因拒绝，而 `'never'` 会在提示前拒绝。
+- 缺失、外部、无 agent、抛异常、无效或断开连接的应答路径都会失败关闭。
+- 成功的请求按精确 agent 归属路由，并追加一对可回放、对模型不可见的审计事件；空闲时和提交前失败的请求会拒绝。
+- ACP 归属把决策限制在其会话内，而没有该服务的部署不产生请求或审计事件。
+
+代价与已接受的局限：
+
+- **两个急于决策的应答者竞争同一槽位。** 兄弟插件的监听器顺序不确定，seam 无法仲裁竞争的终端应答者。通过约定缓解（每个部署一个终端应答者；仅对「先决策或委派」门禁使用 `prepend`），而非事件总线不具备的优先级机制。
+- **生产环境验证依赖单一组合。** `ask` 有两个生产者家族——钩子桥通过 `tools/pre-execute`，沙箱升级通过自己的门禁——协议格式录制在沙箱示例的快照套件中；因此在更多部署组合它之前，seam 的真实覆盖面就是这一种组合。
+- **归属以 `Agent` 对象标识为键。** 应答者先在 `agent.session.id` 处解析会话映射记录，再要求该记录拥有精确的 agent 对象；当前所有路径在 loop 和各 seam 之间传递同一对象，但未来如果某个边界克隆或代理了 agent，桥会委派并失败关闭，届时需要另一种归属契约。
+
+## FAQ
+
+- **在完全没有应答者的部署中（headless、CI）会发生什么？** 每次 ask 穿过空的 waterfall 降级为 `unavailable`，工具调用以「no approval channel is available」原因被拒绝。失败关闭是零监听器的默认行为，不是配置。
+- **授权能持久化吗——「始终允许」？** 不能。`allowed-once` 仅授权单次被询问的操作，服务在请求之间不存储任何内容；`allow_always` 在授权存储设计完成之前刻意不展示（§ 延后）。
+- **模型看到审批的什么？** 只看到发起方从结果派生的工具结果——审计对永远不进入 transcript（文本记录）。三种非授权原因各不相同，模型可以区分人类说「不」、提示被关闭、通道缺失。
+- **谁决定一次调用是否需要 ask？** 策略生产者：返回 `permissionDecision: ask` 的钩子、任何 `tools/pre-execute` 监听器、或沙箱升级门禁。seam 和桥只负责路由和应答；二者都不注入自己对「什么值得弹出提示」的判断。
+- **用户关闭提示或轮次在 ask 进行中中止时会发生什么？** 关闭映射为 `cancelled` 并携带自己的拒绝文本。已中止的 signal 直接结算为 `cancelled` 而不派发；ask 进行中的中止丢弃迟到的应答。当两个审计追加都提交时，任一路径都记录恰好一对事件，绝不会两对。
+- **如果客户端以 harness 从未提供的选项应答呢？** 除已提供的 `allow_once` 之外的任何选项都映射为 `rejected`——来自不合规客户端的未知 optionId 永远不能授权。
+- **subagent 的审批如何路由？** 没有应答者拥有的 agent 穿过整个 waterfall 委派并失败关闭——进程内 subagent 被刻意设计为不可应答。`subagent-acp` 的子侧自动应答是独立的；将子 agent 的 ask 路由到父控制器已延后（§ 延后）。
+- **`policy: 'never'` 在运行时实际改变了什么？** 服务在派发任何应答者之前，将该会话的每次 ask 解析为 `rejected`（在服务内部，因此没有注册顺序能绕过它）；系统提示词声明该策略；切换在边界处被叙述；每次成功的自动拒绝都会记录审计对。
+- **热重载或应答者在会话中途卸载时会发生什么？** 应答者随其拥有的 fiber 一起 dispose，因此下一次 ask 降级为 `unavailable` 而非挂在死通道上；重新挂载会重新注册应答者，无需追赶状态。
+- **客户端从哪里获得审批上下文？** 请求携带精确的 `callId` 和发起方的人类可读 `reason`；通道适配器可自行关联更丰富的工具调用状态，而无需在审批 seam 中重复携带参数。

## Problem
Model-facing tool order followed plugin registration order, which depends on concurrent module loading for otherwise independent plugins. That race produced different request headers in CI and snapshot recordings. Because order affects request bytes, caching, and the durable header, it needs an explicit deterministic policy.

+# Agent Note: 显式的模型侧工具顺序
+
+Status: implemented
+
+[English](2026-07-06-explicit-tool-order.md) | 中文
+
+## 问题
+
+模型侧的工具顺序此前跟随插件注册顺序，而注册顺序取决于相互独立的插件的并发模块加载。这种竞态在 CI 和快照录制中产生了不同的请求头。由于顺序影响请求字节、缓存和持久化的 header，因此需要一个显式的确定性策略。
+
+## 决策
+
+系统提示词的组装逻辑拥有模型侧工具顺序的权威定义，正如它已经拥有 section 顺序的权威定义一样。`dsh-system-prompt` 上的 `toolOrder?: string[]` 是可选的显式策略：
+
+- 列表中已注册的工具按列表位置排列。
+- 列表中的名称没有对应的已注册工具，属于配置错误。形状错误（缺少 rest 条目或名称重复）在服务构造器中快速失败；未注册的名称则在每次 `assemble()` 时拒绝——这是已注册工具集存在并可供检查的最早时刻（工具插件在服务构造之后才注册），也是唯一的通用时刻（注册随时可能变化；Cordis 没有「所有插件已加载」事件）。在已交付的 agent loop（智能体循环）下，第一个轮次在发出任何模型请求之前就会失败——确切的影响范围见下文「后果」。
+- 已注册但不在列表中的工具，插入到 `'<unlisted-tools>'` rest 条目（`TOOL_ORDER_REST`）的位置，与其他未列出的工具按名称字典序排列。
+- 任何已收集的工具不得使用 `TOOL_ORDER_REST` 作为其 `ToolSchema.name`；组装逻辑在排序之前就会拒绝这个保留名称。
+- 列表必须恰好包含一个 rest 条目，且不得有重复名称。
+- 当 `toolOrder` 未设置时，权威顺序为纯字典序（code-unit 比较，与 locale 无关），因此无需配置即可保证确定性。
+
+`assemble()` 在 `system-prompt/assemble` waterfall（瀑布式事件）之前对提供方工具进行规范化排序，从源头消除注册顺序的差异。waterfall 从这个确定性列表开始；不变的顺序随后流入请求头、冻结的请求和重建检查，无需 loop 特有的排序逻辑。
+
+范围刻意收窄：本 Agent Note 修复的是注册顺序竞态，而非插件行为。`system-prompt/assemble` 的监听器仍然可以添加、移除或重排工具——正如它可以在 section 排序之后编辑 section——并对自身输出的确定性负责；waterfall 契约已经要求监听器是确定性的（可重建性不变式会捕获在构建与回放之间行为不一致的监听器）。
+
+配置传递沿用 `persona` 的先例，`toolOrder` 与之并列：TUI、Headless 和 ACP 应用配置接受该键，并通过 `dsh-agent-spine-demo`（其 schema 是各所有者 schema 的交集）转发给 `SystemPrompt` 子服务。有一个 schemastery 细节至关重要：schemastery 数组默认为 `[]`，但省略的 `toolOrder` 必须保持 ABSENT（= 字典序），而不是变成一个显式配置的空列表（无效——缺少 rest 条目），因此链路上每个 schema 都将默认值强制为 `undefined`。
+
+## 曾考虑的替代方案
+
+- **注册顺序（现状）**：并发导入竞态，依赖宿主环境（上述 CI 抖动），评审中不可见。
+- **插件依赖图的线性化**：该关系是偏序的，独立的工具插件不可比较；抖动发生时偏序已完全满足。
+- **每个插件在其工具贡献上标注 `weight`**：将顺序分散到各插件中，仍需一个无人拥有的全局编号约定（section 的 `order` 分段已经展示了这种协调成本需要手工承担）。
+- **在 `ToolRegistry.schemas()` 中排序（注册表层）**：同样确定，但注册表是一个成员存储，被组装之外的多方消费；排序是提示词组合的关注点，而组装逻辑已经拥有 section 的组合策略。
+- **在 `LlmService` 上加配置 + `orderTools()` 方法，由 loop 在记录 header 前调用**：可行，但仅为在远处应用一个策略就增加了一个公开服务方法和一处 loop 改动；每个未来的请求组合者都必须记得调用。在列表诞生处进行规范化使得无序列表不可表示，且零新增接口。
+- **在 `llm.stream()` 内部规范化**：在 header 事件已记录之后才运行（抖动仍然存在），且需要重建深度冻结的信封，静默地解除了重建不变式。
+- **穷举列表（无 rest 条目）**：每个新加载的工具插件都会导致启动失败；强制的 rest 条目使未列出的工具保持确定性，且其位置是显式的。
+- **启动时校验（由 `dsh-app-boot` 在 `loader.await()` 之后调用 `SystemPrompt.assertToolOrderSatisfied()`）**：能将错误配置变为启动时死亡而非首轮次失败，但代价是一个公开服务方法加上通用启动胶水对单个服务的结构耦合，且无法替代组装时检查（嵌入式调用者从不运行 app boot；注册在 boot 之后仍会变化）。也没有现成事件可以承载该检查：Cordis v4 没有 ready 类事件，`loader/entry-init`/`internal/status` 在加载中途触发（与工具注册存在竞态——正是本 Agent Note 要消除的熵源），而 agent 生命周期事件不会早于组装。在 `assemble()` 设置单一执行点被判定值得接受较晚的失败时刻。
+
+## 后果
+
+- 每个由注册表构建的组装在任何宿主上都以确定性工具顺序开始；在没有专家监听器刻意改变的情况下，每个 `request/header` 事件和模型请求都继承该顺序。CI 与本地之间的注册顺序翻转从结构上被消除，默认为字典序。
+- 初始 `PromptAssembly.tools` 是权威的，因此 waterfall 监听器从模型侧顺序开始；提供方注册顺序在该协作 seam 之前无处可观测。
+- 快照套件中唯一固定请求头的 fixture（`text-turn`）携带新的权威工具顺序；按照固定请求头设计，其他 ACP 快照仍将大块 header 清洗为 `{{system}}`/`{{tools}}`。
+- 步骤之间的纯工具重排与其他 header 变更一样记录：一份原因是 `'change'` 的完整 `request/header` 快照。稳定的权威顺序会防止注册时序在普通路径上制造这类变化。
+- `toolOrder` 键沿 app → `agent-core` → `SystemPrompt` 的转发链传递，因此部署时将其放在 app 配置中 `persona` 旁边即可；`dsh-llm` 和 agent loop 无需改动。
+- `toolOrder` 中拼错或未加载的工具名称在提示词组装时使轮次失败，而非启动时：loop 在轮次内部组装（`turn/start` 之后、`step/start` 之前），因此拒绝到达轮次的外层 catch——轮次以 `error` 原因平衡关闭并携带错误消息，`agent/error` 镜像该消息，不打开步骤，不记录 `request/header`，不向适配器发出请求，agent 回到空闲状态。每个轮次都以相同方式失败，直到配置被修正；进程本身保持运行（符合仓库规则：显式配置引用不得被静默忽略——执行点是组装，因为不存在更早的通用时刻）。
+- 工具提供方返回保留的 rest 条目名称时，其提示词组装失败形态与未知的已列名称相同。这防止哨兵值变成一个歧义的真实工具，并保持「从不丢弃工具」的排序契约。
+
+## 测试
+
+系统提示词测试覆盖：字典序默认顺序、列表/rest 位置、提供方顺序无关性、共享名称、无效列表、未知或保留名称、waterfall 前的权威列表，以及监听器添加的工具不被重新排序的规则。Loop 测试固定：跨注册排列的已记录与已分发顺序一致、通过 agent-core 和两个 app 的转发、深度冻结的请求，以及在配置了未知名称时的平衡轮次失败（无步骤、无 header、无适配器调用）。快照回放仅在固定的 `text-turn` header 中保留完整的权威列表；其他 fixture（测试前置数据）继续使用 `{{tools}}`。

## Problem
A coding agent needs this product path: bash subprocesses — and the hook commands that ride them — execute under a restricted file sandbox by default; if and only if the sandbox actually denies an operation, the model may request one user approval for that same operation and, once granted, retry it once with wider permissions. An every-tool boundary is deliberately NOT the claim: fs/web/todo execute in-process where an `execve` wrapper is meaningless (§ In-process tools), and the cross-family boundary is staged follow-up work (§ Deferred phases). Without a shared vocabulary, every tool reinvents approval fields, denial parsing, retry matching, and permission-state hints.
The harness is an SDK, so confinement must be a capability developers COMPOSE: whether to sandbox, and which backend per platform, belongs in the leaf `cordis.yml` as a first-class entry — not inside one executor's private machinery. And the first-choice runner, `bwrap`, is unusable on exactly the hosts a sandbox matters most (minimal containers, disabled unprivileged userns, LSMs that deny `mount`), so a fallback runner has to ship with the SDK rather than be assumed on the host.
-Confinement alone leaves two gaps. A denial with no escalation path is terminal — the model can only give up, which pressure-cooks operators into configuring `workspace-write` or `danger-full-access` globally and defeats the sandbox. And the model-visible knobs (the sandbox mode, the approval policy) change over an agent's lifetime — an ACP user flips a per-session setting, an operator edits `cordis.yml` while the process is down — while the model must never act on a stale belief about them: what IS the state on every request, what changed while the agent lives, and what changed while nobody was watching all need answers.

Misconfiguration fails loud: `mode` outside the closed vocabulary is rejected at plugin load, and a host with no usable backend throws the structured `SANDBOX_UNAVAILABLE` — at `confine()` before the command ever spawns — rather than degrading to unconfined execution. `runnerCommand` on `dsh-sandbox-local` is the operator's explicit assertion of a bwrap-compatible runner (chain and probes skipped); it doubles as the deterministic fake-runner seam for keyless tests.
-Denied file effects return a `[sandbox: file access denied under <mode> mode]` marker and instructions not to work around the denial. A confining executor adds paired `sandbox_permissions` and `justification` fields for one approved retry that must be strictly wider than the session's effective mode. A grant widens only that retry; rejection executes nothing, returns `the user rejected escalating this command to "<mode>"`, and permits no re-ask. The prompt does not announce sandbox mode, avoiding preemptive refusal. When `dsh-permission` is composed, ACP exposes one `Permissions` select whose presets write both knob events; unmatched knobs appear as switch-away-only `custom`. Only a switch to the deterministic `'never'` approval policy is stated in the prompt and narrated.

### Design detail
#### Scope grounding
-OS subprocess confinement applies to the bash executor, including hook commands, and later to ACP subagent children. Filesystem, web, and other tools execute in-process and require policy at their own seams; an argv wrapper cannot confine a function closing over `ctx`. The existing bash request/spec split carries per-call overrides, while `tools/pre-execute` and the approval seam own the human decision.

Sandbox mode is not narrated in the prompt; denial results report the mode when it matters, avoiding preemptive refusal based on a standing label. Approval policy is different: only `'never'` is stated because automatic rejection otherwise looks like a user decision. Policy-change notices are coalesced and delivered by the next pre-step, with log-derived fallback after restart. The notice source is inferred from event position: a knob event after the last request header is user-driven; unlogged drift is operator or config driven.
-**The editor surface** is protocol-native [Session Config Options](https://agentclientprotocol.com/protocol/session-config-options) — the spec's replacement for session modes (slated for removal in ACP v2), already SDK-typed. When `ctx.permission` is composed, the bridge advertises one `permission` select (category `mode`) in `session/new` and `session/load`; its options are the deployment's preset table, and its `currentValue` is `PermissionService.current()` over the session log plus composition defaults. The shipped `workspace-write` and `danger-full-access` presets each bundle a sandbox mode with an approval policy and write through to both domain setters; a knob combination outside the table is reported as switch-away-only `custom`. `session/set_config_option` validates and switches through the permission service, then returns the complete refreshed state (the spec contract).
+**The optional UI surface** is `PermissionService`: a deployment-defined preset table whose entries bundle one sandbox mode with one approval policy. The shipped `workspace-write` and `danger-full-access` presets write through to both domain setters; a knob combination outside the table is reported as `custom`. UI adapters may expose that table as a selector. The automation-only ACP transport advertises no configuration selector and mounts no permission-preset service.
-**Turn enclosure is the commit boundary.** A switch during an open turn appends immediately. An idle switch remains pending on the bridge record and is appended at the next prompt submission, before assembly or execution; last write wins per knob. Openness comes from log boundaries rather than `agent.status`, and setters do not append from inside a `session/event` listener because that would reorder later observers. Until anchoring, responses overlay the pending value. A crash discards it, and reload returns the durable fold.
+**The committed event is the commit boundary.** A runtime switch records its preset and changed knob events on the target session, and every later capability resolution folds the last values.

+- **When does a runtime mode switch take effect?** Once its session event commits, the very next capability resolution folds and stamps the new mode. The model is not told a standing mode; its next command simply behaves under the new policy, and any denial names that policy at the point of use.
- **What survives a restart — and what if the operator changed the config default while the process was down?** Overrides replay from the session log (`effective = fold ?? config`), so a resumed session keeps its modes with zero catch-up machinery; a default that drifted offline changes behavior the same way a switch does (the approval policy, being stated, is additionally narrated with operator/config attribution).
- **What does `enforcement: 'partial'` on a result mean?** The selected backend enforces the subset its kernel ABI governs — e.g. Landlock before ABI v3 does not govern path truncate — and says so structurally instead of refusing the host; the probe's report line distinguishes the cases. The bwrap and Seatbelt profiles govern every promised file effect by construction, so they always report `full`.

+# Agent Note: 子进程沙箱——约束 seam、原生 runner、升级机制与按会话模式
+
+Status: implemented
+
+[English](2026-07-06-sandbox.md) | 中文
+
+## 问题
+
+一个编码 agent 需要如下产品路径：bash 子进程（以及依附其上的钩子命令）默认在受限的文件沙箱下执行；当且仅当沙箱实际拒绝了某个操作时，模型可以为同一操作请求一次用户批准，获批后以更宽的权限重试一次。本设计刻意不声称覆盖所有工具：fs/web/todo 在进程内执行，`execve` 包装对它们毫无意义（§ 进程内工具）；跨工具族的统一边界属于分阶段后续工作（§ 延迟阶段）。如果没有共享词汇，每个工具都会各自重新发明批准字段、拒绝解析、重试匹配和权限状态提示。
+
+harness 是一个 SDK，因此约束必须是开发者可组合的能力：是否启用沙箱、每个平台使用哪个后端，都应作为一等条目写在叶子 `cordis.yml` 中，而非藏在某个执行器的私有机制里。而首选 runner `bwrap` 恰恰在沙箱最重要的主机上不可用（精简容器、禁用了非特权 userns、LSM 拒绝 `mount`），因此备选 runner 必须随 SDK 一起交付，而不能假设主机已有。
+
+仅有约束还留下两个缺口。拒绝后没有升级路径就是死路：模型只能放弃，这会迫使运维人员全局配置 `workspace-write` 或 `danger-full-access`，从而使沙箱形同虚设。而沙箱模式和批准策略也会通过部署配置或可选的 UI 策略控件在 agent 生命周期内变化；执行与模型可见的策略必须派生自同一份已记录的状态。
+
+## 决策
+
+一个 seam、一条按平台的本地后端链、一个消费方，加上两个上层杠杆：按调用的升级路径与按会话的运行时模式。以下所有内容均从叶子 `cordis.yml` 组合而来；不触及 `agent-loop`。跨工具族 fs 强制与按会话工作区根目录已经作为后续设计落到同一策略载体上；剩余阶段——`subagent-acp` 消费方、更多环境与 Windows 链——仍列在 § 延迟阶段。
+
+### 部署方式
+
+四条 `cordis.yml` 条目即可将一个无约束的编码 agent 转变为沙箱产品路径；[`examples/acp-agent`](../../../../examples/acp-agent/README.md) 默认使用此组合：
+
+```yaml
+- id: sandbox
+ name: '@deepseek-ai/dsh-sandbox-local' # the per-platform runner provider (ctx.sandbox)
+- id: bash
+ name: '@deepseek-ai/dsh-bash-sandbox' # the confined executor, replacing dsh-bash-local behind ctx.bash
+ config:
+ mode: workspace-write # the deployment default every session starts from
+ workspaceRoot: !!js process.cwd() # the boundary workspace-write may write under
+- id: approval
+ name: '@deepseek-ai/dsh-user-approval' # the escalation gate's channel (the approval Agent Note)
+ config:
+ policy: ask
+- id: permission
+ name: '@deepseek-ai/dsh-permission' # one product-facing select over both mechanism knobs
+```
+
+这一替换对 `ctx.bash` 的所有消费方透明：bash 工具、钩子命令和后台任务照常运行，通过提供方返回的包装 argv spawn。删除 `sandbox` 和 `permission` 条目、将 `bash` 替换为 `@deepseek-ai/dsh-bash-local` 即为退出——执行恢复为无约束，升级字段从工具 schema 中消失，因为它们是基于已挂载执行器的能力门控，而非基于配置。仅省略 `approval` 则保留约束但以自身错误文本关闭每次升级；`permission` 还要求 approval seam 和约束执行器同时存在，因此部分组合的 preset 层在加载时即大声失败。
+
+配置错误大声失败：`mode` 不在封闭词汇中时在插件加载时被拒绝；主机上没有可用后端时在 `confine()` 阶段（命令 spawn 之前）抛出结构化的 `SANDBOX_UNAVAILABLE`，而非降级为无约束执行。`dsh-sandbox-local` 上的 `runnerCommand` 是运维人员对一个 bwrap 兼容 runner 的显式断言（跳过链和探测）；它同时充当 keyless 测试的确定性 fake-runner seam。
+
+被拒绝的文件操作返回 `[sandbox: file access denied under <mode> mode]` 标记，并附带不要绕过拒绝的指令。约束执行器添加配对的 `sandbox_permissions` 和 `justification` 字段，用于一次经批准的重试，该重试必须严格宽于会话的有效模式。授权仅放宽该次重试；拒绝则不执行任何内容，返回 `the user rejected escalating this command to "<mode>"`，且不允许再次请求。提示词不声明沙箱模式，以避免基于常驻标签的预防性拒绝。当 `dsh-permission` 与某个 UI 适配器一起组合时，一个 preset 同时选定两个旋钮值；不匹配的组合折叠为 `custom`。[ACP 自动化组合](../../../../examples/acp-agent/README.md)不挂载该 UI 服务，而是显式选定其部署模式。
+
+### 设计细节
+
+#### 范围界定
+
+OS 子进程约束适用于 bash 执行器（包括钩子命令），后续还将适用于 ACP subagent 子进程。文件系统、web 和其他工具在进程内执行，需要在各自的 seam 层面实施策略；argv 包装无法约束一个闭包了 `ctx` 的函数。既有的 bash request/spec 拆分承载按调用的覆盖，而 `tools/pre-execute` 和 approval seam 负责一次性策略决策。
+
+#### seam：`ctx.sandbox`
+
+`dsh-sandbox` 拥有词汇和 `SandboxProvider` 契约：`confine(argv, policy)` 返回调用方应当 spawn 的替代 argv（经过包装，使进程及其所有子进程在约束下运行），加上所选后端达到的 `enforcement` 完整度、其拒绝方言（`denialSignatures`，该后端内核在拒绝文件操作时打印到 stderr 的子串）、以及其 runner 失败方言（`runnerFailureSignatures`，runner 本身失败——因而命令从未运行——时的自我标识方式）；没有可用后端时抛出失败关闭的 `SANDBOX_UNAVAILABLE` 错误，绝不静默放行。词汇：`SandboxMode`（`read-only` / `workspace-write` / `danger-full-access`，仅限文件操作——不声称覆盖网络和进程可见性）、`SandboxEnforcement`（`full` / `partial`）、`SandboxExecutionPolicy`（每次能力调用的完整 mode + workspace root）以及 `SandboxPolicy`（提供给约束后端的子集）。
+
+策略随每次调用而非提供方携带：两个消费方可以在同一时刻以不同策略约束（bash 在 `read-only` 下运行，而一个受约束的子 agent 保持其状态目录可写），且经批准的升级重试是一次带有更宽策略的新调用——在配置固定的提供方模式下无法表达。
+
+该 seam 仅约束与宿主机共享文件系统和内核的子进程。容器、microVM 和远程执行器不是此 seam 的后端——它们以环境一致的组替换整个能力实现（`ctx.bash`、`ctx.fs`），因为一个 bash 在容器中运行而 fs 工具写主机的 agent 生活在两个割裂的世界中。
+
+留待需要时再决定：网络限制是作为独立的 `network_mode` 到来，还是在某个 runner 同时强制两者后合并进 `sandbox_mode`；以及 `SandboxPolicy` 是现在就增加额外的可写根授权（launcher 已支持 `--rw <path>`），还是等到升级机制需要时再加。
+
+#### 本地后端与随附 launcher
+
+`dsh-sandbox-local` 在提供方生命周期内选择一个平台 runner 并缓存结论。Linux 功能性探测 `bwrap` 然后 Landlock；macOS 使用 Seatbelt。不支持的平台和不可用的 runner 失败关闭。每次包装携带后端特定的拒绝签名和 runner 失败签名，以便 `dsh-bash-sandbox` 区分被拒绝的文件操作与损坏的沙箱。`runnerCommand` 作为运维人员对 bwrap 形状 runner 的断言跳过选择，但缺失或不可执行的命令仍被归类为沙箱失败，绝不无约束地运行负载。
+
+launcher 是一个约 300 行的 C 程序（纯 C11，直接使用 Landlock UAPI——除静态链接的 musl 外无其他库，因此审计面仅为该文件加内核的稳定 syscall 契约）：`--ro <path>` / `--rw <path>` 授权，`--`，被包装的 argv；它在自身上安装规则集并 `exec`（规则集跨 `execve` 继承，且它在限制前设置 `no_new_privs`）；`--probe` 在一个短生命周期子进程中强制最大规则集，仅当内核确实强制时才以 0 退出；launcher 失败以 125 退出且不 exec。
+
+Landlock launcher 源码和包工作区位于 `native/landlock-run`，与 harness 消费方同仓。独立的 [`node-addon-landlock-run`](https://github.com/deepseek-harness/node-addon-landlock-run) 仓库是用于打包并发布 npm 包族的发布镜像；导出流程归 `native/README.md` 所有。平台二进制由 npm 选择，入口包拥有路径解析、探测和 CLI flag，而 harness 将沙箱模式映射为授权。将入口点与其二进制一起版本化，使探测解析和启动语法保持对齐。
+
+后端 profile 共享模式契约但在必要的主机授权上有所不同。Landlock 和 Seatbelt 在 read-only 模式下仅允许 `/dev/null`；workspace-write 还允许各自所需的主机临时目录根。每次包装携带后端特定的拒绝签名。Landlock 在较旧的 ABI 无法管控所有操作时报告 partial enforcement，而成功的 bwrap 和 Seatbelt profile 报告 full enforcement。
+
+#### bash 消费方
+
+`dsh-bash-sandbox` 扩展 `LocalBashExecutor`，并把即将 spawn 的确切 `['bash', '-c', command]` argv 交给 `ctx.sandbox`。拒绝是与其他结果正交的事实，依据当前 runner 的 stderr 方言保守分类。Runner 失败优先于拒绝：前台执行抛出 `SANDBOX_UNAVAILABLE`；结算后的 `BashProcess` 会盖章 `sandbox.runnerFailed`，bash 生产者再通过通用 `task_output` 渲染它。
+
+模型看到的仅是结果事实：静态工具描述解释拒绝标记（`[sandbox: file access denied under <mode> mode]`），鼓励尝试可能被拒绝的命令，并禁止绕过拒绝重试；当升级字段被公布时，被拒绝的结果还额外携带升级提示本身，使被认可的同轮次重试在决策点被提示，而非依赖模型回忆描述（§ 升级机制）。没有提示词段落声明沙箱模式（§ 按会话模式）。
+
+#### 升级机制：拒绝后一次经批准的更宽重试
+
+`BashExecRequest.sandboxPolicy` 是可选的完整按调用输入；解析后的 spec 使该字段显式。`BashExecutor.sandboxMode` 仍是公布已挂载执行器能否兑现该策略的能力事实，因此只有约束组合才暴露升级。seam 接受任何显式策略；工具拥有会话解析和「仅更宽」的升级规则。非沙箱执行器诚实地保持无约束。
+
+`ctx.sandboxPolicy.resolve()` 在执行器运行前盖章完整执行策略——显式升级模式 > 会话覆盖 > 配置默认值，且 `SessionHeader.cwd` > 配置的后备根目录。`SandboxBashExecutor.resolve()` 在 spec 上保留该策略，或为直接的无 agent 调用方提供部署后备值，使 `run()`/`start()` 永不读取可变会话状态。每进程包装事实以返回的 `BashProcess` 为键；`onProcessDone()` 在 `done` 结算前分类 stderr 并给该句柄盖章，因此重叠进程各自保留自己的模式和 runner 方言。
+
+当约束执行器被挂载时，`bash` 公布配对的 `sandbox_permissions` 和 `justification` 字段。schema 暴露完整的封闭升级词汇，因为有效模式是按会话的；执行拒绝任何不严格宽于该调用有效模式的目标。批准在执行之前解析。`allowed-once` 仅将授权模式盖章到该请求上，而 `rejected`、`cancelled`、`unavailable`、缺失的 approval 服务或缺失的 agent 都以各自不同的结果文本失败关闭。授权不持久化。
+
+升级是对被拒绝命令的同轮次重试，使用最窄的足够 `sandbox_permissions` 和一个 `justification`；批准提示是同意步骤。它必须基于实际的拒绝，除非会话已观察到相同的被拒绝访问；禁用或被拒绝的批准终结该命令。重试、批准决策和结果使用既有的工具和批准事件。`dsh-tool-bash` 拥有请求动作，因为执行器 seam 既没有 agent 也没有用户交互所需的 call id。
+
+仍未决定：持久授权超出沙箱模式之外的作用域标识是什么——确切调用、路径、命令前缀、会话或时间窗口——这是公布 `allow_always` 选项之前必须回答的问题。
+
+#### 按会话模式：会话日志即存储
+
+```
+effective(session) = findLast(the session's own knob events)?.value ?? the composition-config default
+```
+
+默认值是组合配置（`cordis.yml`）——运维人员拥有，进程范围。运行时切换是会话范围的覆盖，记录为该会话自身日志中的一条仅日志事件。重启免疫（恢复会话时回放其日志，覆盖自然恢复，无需追赶机制）和多会话隔离都是构造性的自然结果，且不存在任何外部配置存储。
+
+**每个旋钮一种事件，由其领域拥有**——这是每个既有事件族已遵循的可合并扩展 `SessionEventMap` 惯用法（`dsh-user-approval` 中的 `approval/*`、hooks 包中的 `hook/*`）：
+
+```ts
+interface SessionEventMap {
+ 'sandbox/mode': { mode: 'read-only' | 'workspace-write' | 'danger-full-access' }
+ 'approval/policy': { policy: 'ask' | 'never' }
+}
+```
+
+每个拥有者导出相同的三件套：事件声明、纯 fold（`effectiveSandboxMode(events)` / `effectiveApprovalPolicy(events)`——一个 `findLast`，类型化到领域的封闭联合），以及唯一的写入路径（`setSandboxMode(session, mode)` / `setApprovalPolicy(session, policy)`——切换即其事件；没有任何东西在带外修改状态）。无共享拥有者服务、无通用 facts map、无注册表：第三个旋钮只需将约 40 行模式复制到自己的包中。执行在两侧都遵循 fold——bash 工具的按调用盖章将其作为 § 升级机制优先级链的中间层读取，approval seam 的 `'never'` 门控是[批准 Agent Note](2026-07-06-approval-seam.md) 同一模式的另一侧。
+
+沙箱模式不在提示词中叙述；拒绝结果在需要时报告模式，避免基于常驻标签的预防性拒绝。批准策略不同：只有 `'never'` 被声明，因为自动拒绝在行为上与用户的「不」无法区分。策略变更通知被合并，由下一个步骤前检查点递送，重启后有基于日志的回退。通知来源从事件位置推断：最后一个 request header 之后的旋钮事件是用户驱动的；未记录的漂移是运维人员或配置驱动的。
+
+**可选的 UI 界面**是 `PermissionService`：一张部署定义的 preset 表，每个条目捆绑一个沙箱模式与一个批准策略。随附的 `workspace-write` 和 `danger-full-access` preset 写入两个领域 setter；preset 表之外的旋钮组合报告为 `custom`。UI 适配器可以把该表暴露为选择器。仅面向自动化的 ACP 传输层不公布任何配置选择器，也不挂载权限 preset 服务。
+
+**已提交的事件是提交边界。** 运行时切换在目标会话上记录其 preset 和发生变化的旋钮事件，之后每次能力解析都折叠最后的值。选择有效的会话追加边界由适配器负责；ACP 传输层没有运行时切换路径。（原先 ACP 的空闲切换锚定——将待定的空闲选择保留到下一次提示词提交——已随该桥一并移除。）
+
+#### 进程内工具
+
+fs/web/todo 在进程内执行，因此它们的沙箱语义是各自 seam 层面的策略。fs seam 现在通过沙箱提供方强制共享模式词汇（`dsh-fs-sandbox` 按模式限制 write/edit；见[跨工具族 fs 沙箱 Agent Note](2026-07-14-cross-family-fs-sandbox.md)），因此 `read-only`/`workspace-write` 对文件系统工具也是真实边界，而非仅限 bash 的近似。web/todo 仍不受限制（web 的唯一效果是网络，不在文件效果模式词汇内）。没有通用的按工具沙箱运行时：主机中介的工具仅通过返回主机验证的声明式效果来离开进程，那是一次重写而非包装——后续设计选择了一个共享策略归属 `ctx.sandboxPolicy`，由各 seam 强制，而不是统一包装器。
+
+### 测试
+
+- **单元测试：** 固定平台选择和 profile、失败关闭的 runner 分类、按调用的模式/根目录解析、按进程事实、升级验证和结果、权限 preset fold 和写入透传、以及叙述器合并。
+- **Keyless 真实 runner：** 在提供方和 bash 消费方层面对 bwrap、Landlock 和 Seatbelt 执行真实文件系统效果测试；一个真实 Cordis 上下文通过已交付的 bash 和 fs 工具并发驱动两个项目会话，证明在自身根目录写入成功、在兄弟根目录写入被拒绝。Packed-install 覆盖率证明注册表 launcher 保持可执行。CI 拒绝静默全跳过。
+- **With-key：** 以只读模式启动真实 ACP 组合，让模型驱动的 bash 写入命中 runner 的拒绝标记，再通过已授权与被拒绝的 workspace-write 重试驱动 bridge 应答器和磁盘效果；不可用的凭证或 runner 自动跳过。
+- **快照：** 固定提示词 delta 和通知，以及两个脚本化的 approval 分支。一个真实 ACP 示例场景把会话放在用户主目录下，同时让部署后备根目录指向 `/tmp`，然后固定一次成功的、由部署选定的 workspace-write 变更；这能区分会话根目录解析与进程后备值，而不依赖 runner 特定的拒绝文本。其他快照以无约束启动，使无关 fixture（测试前置数据）保持平台无关。
+
+## 延迟阶段
+
+每个阶段在被拾起时获得完整设计，对照当时的代码验证，并在其涉及的层级带上单元测试、真实 API e2e 和快照覆盖率落地。
+
+- **第二个消费方**——`subagent-acp` 可选地约束子 agent（按调用策略；默认无约束——子 agent 必须写入自己的持久化）。
+- **更多环境**——环境一致的能力组示例（如 bash+fs 对一个容器）。
+- **Windows 链**——`PLATFORM_CHAINS.win32` 保留为空（失败关闭）；填充它意味着来自 AppContainer/restricted-token 家族的约束 runner，从其自己的仓库按 `node-addon-landlock-run` 模板交付，加上其 profile 方言和拒绝/runner 失败签名。
+
+## 曾考虑的替代方案
+
+- **命令字符串启发式预检**：否决。无法理解展开/子进程/符号链接；严格尝试（运行它，让内核决定）是唯一可信的拒绝信号。
+- **即使平台仅有一个后端也功能性探测**：否决。探测用于在候选者之间仲裁；只有一个时无需决策，且探测开销对每个会话的首次约束命令征税（对未来重量级后端而言代价过高）。runner 自身执行时的失败关闭拒绝加 `runnerFailureSignatures` 分类承载了安全属性。
+- **提交构建好的 launcher 二进制**：否决。diff 中的二进制不可审查且膨胀历史；经审查的源码 + 原生 CI 构建 + launcher 仓库的字节固定发布演练使二进制远离所有代码树。
+- **安装时编译 launcher**：否决。将 C 工具链强加给每个消费方；仅在碰巧有编译器时才存在的备选不是备选。
+- **从一个构建器交叉编译两种架构**：否决。仅为重建两个约 70 KB 的二进制就需要携带一个固定的交叉工具链（rustup targets、zig 或容器镜像）；每架构的原生 runner 已存在，各自构建自己的平台包（`node-addon-require-builtin` 模式，launcher 仓库自己的流水线）。
+- **无备选（bwrap 或失败关闭）**：否决。将失败集中在沙箱最重要的主机上，最终因放弃而降级到 `danger-full-access`。
+- **将机制保留在 `dsh-bash-sandbox` 内部**：否决。阻塞既有的第二个消费方，使未来阶段从一个 bash 插件的配置中读取模式，且无法表达升级。
+- **提供方上的配置固定模式**：否决。每进程一个模式；无法服务具有不同策略的并发消费方，也无法表达一次性放宽重试。
+- **一个接口同时覆盖容器/VM**：否决。`confine(argv)` 预设共享文件系统；环境隔离是作为一致组部署的能力兄弟后端。
+- **通用 ToolRuntime 包装任何工具**：否决。对进程内工具（闭包了 `ctx`）机械上不成立；声明式效果重写对 fs/web/todo 而言不合理。
+- **在执行器内部（`dsh-bash-sandbox`）请求批准**：否决。没有可路由的 `agent`，没有可附加提示词的 `callId`；添加它们会让传输 seam 了解会话和 UI——工具层持有两者并拥有面向模型的词汇。
+- **同一工具调用内自动重试**：否决。日志无法重建的隐藏重入：一个 `tool/call` 会产生两次具有不同策略的执行——重试是一次新的带有自身参数和结果事实的已记录调用。
+- **无条件公布升级字段**：否决。在 `dsh-bash-local` 下它们是死杠杆——公布 harness 无法兑现的选项会制造注定失败的授权；能力门控仅需注册时一次读取。
+- **默认值相对的升级阶梯（仅公布比执行器注册时默认值更宽的模式）**：否决。按会话覆盖使默认值成为错误的基线——切换到比默认值更窄的会话恰恰失去它需要的杠杆，而在 `danger-full-access` 默认值下字段完全消失，同时一个被覆盖为 `read-only` 的会话仍处于约束中却没有升级路径。枚举固定封闭的目标词汇；严格放宽是针对会话有效模式的按调用执行检查。
+- **按会话动态工具 schema**：否决。schema 设计上是注册表全局的（一套 assembly 词汇、固定 header 快照契约），按会话重新注册只能买到执行时严格放宽检查已保证的东西，代价是按会话的 schema 表面和每次切换的 header 变动。
+- **将重试硬匹配到先前的拒绝**：否决。命令字符串同一性脆弱（引号、`workdir`、env 前缀、作为失败阶段重试的管道）——要么误拒诚实的重试，要么被轻易满足；真正的边界是人看到命令 + 理由。仅在 `allow_always` 授权存储需要机器可检查的范围时才重新考虑。
+- **通用 `env/state` facts map 加拥有者服务**：否决。approval 和沙箱独立组合，因此任何一方的状态都不应拖入第三个包；单键 fold 各自是一个 `findLast`，拥有者服务自然消解；没有跨旋钮的不变式，因此原子多键补丁无收益。
+- **通过 `agent/user-message` + 总线事件叙述**：否决。它预设了一个不存在的轮次入口 seam（真正的 seam 是 `agent/prompt-submit`），而步骤前检查点的位置使一个监听器能够同时服务合并的轮次入口通知和轮中即时性约束。
+- **提示词中常驻声明沙箱模式（+ 切换叙述器）**：先交付后移除，基于实际证据：当每个请求中都有 `Bash commands run under the "read-only" file sandbox.` 时，模型拒绝尝试被拒绝后可升级的工作（首次手动会话中十二个轮次有五个以零工具调用结束），将沙箱变成了软锁定。拒绝标记在需要时命名模式，升级字段承载恢复路径；批准旋钮保留其声明，因为自动拒绝在行为上与人的「不」无法区分。
+- **用专门的簿记事件追踪「上次告知」**：否决。`request/header` fold 已记录模型看到的确切提示词；将封闭的候选句子解析回来替代了第二条簿记流——事件仅在它们本身即为存储时才需要。
+- **相互独立的沙箱与批准选择器**：否决。一个部署定义的权限 preset 让两个策略旋钮对暴露运行时切换的 UI 客户端保持一致。
+
+## 后果
+
+已交付并固定的内容——测试中的各层级分别保障：
+
+- 被拒绝的命令以 `sandbox_permissions` + `justification` 重试时，通过组合的应答器链提示用户；授权使该次调用在更宽模式下运行（结果事实如此报告），而其他所有调用保持各自的有效模式；每种非授权结果产生各自不同的错误文本且不执行任何内容。
+- 升级字段恰好在已挂载的执行器约束时存在；不严格宽于调用有效模式的请求以自身文本失败关闭且不提示任何人；没有 ApprovalService 的部署对升级调用失败关闭，对普通调用不影响。
+- 系统提示词从不声明沙箱模式（批准 `'never'` 策略是唯一被声明的旋钮），且整个交互——header、旋钮事件、通知、批准、结果——仅从会话日志即可重建，除两个旋钮事件外无额外事件类型。
+- 一次 preset 选择只记录发生变化的旋钮值，而无操作的选择不记录任何内容；批准策略切换最多以一条合并通知叙述，已提交的沙箱切换由下一次调用的盖章兑现。
+- 恢复的会话的覆盖直接生效，无需追赶状态；进程停止期间变更的默认值在会话的首个新请求前被叙述，归因于运维人员。
+- 两个并发会话永远看不到彼此的状态或通知。
+- 同一个 Cordis 上下文中的两个并发项目会话解析各自独立的工作区根目录；bash 和 fs 写入在调用方会话的 cwd 内成功，对其相邻会话的 cwd 则失败。
+- `agent-loop` 未被触及——一切搭载 `systemPrompt.section`、`SessionEventMap` 合并、`agent.inject()`、`agent/pre-step`、`agent/prompt-submit` 和由能力拥有的策略解析。
+
+代价与已接受的限制：
+
+- **单一包装的幻觉被有意放弃。**`tools/pre-execute` 包装加提示词约定无法解决沙箱批准——正确的设计需要结构化拒绝、原生 runner 探测、按调用策略承载和一致的跨工具族强制，本设计为此付出了代价。
+- **`read-only` 通过后续设计成为跨工具族边界。** 本 Agent Note 最初只交付 bash 强制；[跨工具族 fs 沙箱 Agent Note](2026-07-14-cross-family-fs-sandbox.md) 通过沙箱化的 `ctx.fs` 提供方把同一模式词汇扩展到文件系统工具，并将 mode/root 配置和 `sandbox/mode` 覆盖迁移到 `ctx.sandboxPolicy`（§ 进程内工具）。
+- **Windows 没有后端。** 其链槽保留为空——失败关闭，绝不穿透；填充它是延迟阶段。
+- **Seatbelt 层级依赖 Apple 已弃用但仍交付的 `sandbox-exec` CLI。** 作为 darwin 的唯一候选，它无需探测即被选中，因此未来移除会在执行时作为 runner 失败分类浮现——重新抛出 `SANDBOX_UNAVAILABLE`，命令从未运行；失败关闭，绝不开放。
+- **Landlock 约束的完整度取决于运行内核的 ABI。** 报告为 `enforcement: 'partial'` 而非拒绝——这是有意的权衡，使备选在旧内核主机上仍可用。
+- **launcher 作为注册表依赖到达。** 通过其自身仓库的发布流水线（经审查的 C 源码、原生 CI 构建器、字节固定的发布演练）加上本仓库的版本固定获得信任——真实内核 e2e 测试腿是通过安装字节为行为背书的。
+- **模型可能过度请求。** 在没有拒绝依据的情况下升级，或在 `workspace-write` 足够时选择 `danger-full-access`：描述引导且枚举强制阶梯，但人的提示词是实际门控；`approval/asked` 原因使过度请求可审计，且 `prepend` 策略应答器可以自动拒绝部署永远不想要的模式。
+- **公布的目标集是静态的，而有效模式是按会话的**（schema 是注册表全局的）——已处于最宽模式的会话仍被提供这些字段。构造上无害：执行时的严格放宽检查（而非枚举）是安全边界——非放宽请求以自身文本失败且不提示任何人。
+- **授权的升级不等于可工作的沙箱。** 不可用的后端即使对授权升级到约束模式也仍然失败关闭——在平台没有链或所有探测失败时于 `confine()` 阶段，在未探测的唯一 runner 拒绝时于执行阶段（归类为沙箱失败而非命令失败）——而授权的 `danger-full-access` 运行根本不触及提供方：此时授权（而非探测）是权威。
+- **批准叙述器的重启基线解析提示词文本。** 封闭的候选句子由写入模块本身拥有，因此措辞变更是同一文件中写入器+解析器的协调编辑；header 早于该段落的会话静默采用当前策略而不发通知。
+- **批准段落仍是动态提示词表面**（`'never'` 切换会破坏该会话的提供方提示词前缀缓存）。已接受：策略切换罕见，且模型基于过时的 `'never'` 行动更糟。沙箱旋钮不再触及提示词。
+- **模型可能持有关于沙箱模式的过时信念**（没有任何东西宣布切换）。有意接受：下一次尝试的标记或成功会纠正它，而宣布的观察到的失败模式——预防性拒绝——比一次浪费的重试更糟。
+
+## FAQ
+
+- **一个命令返回了 `[sandbox: file access denied under read-only mode]`——它失败了吗？** 它运行了，内核拒绝了一个文件操作：拒绝是与退出码正交的结果事实。教学禁止绕过它重试；唯一被认可的动作是以升级请求重试同一命令一次。
+- **如何区分损坏的沙箱与失败的命令？** Runner 失败在分类中优先于拒绝：匹配包装的 `runnerFailureSignatures` 的失败运行意味着命令从未运行——前台重新抛出结构化的 `SANDBOX_UNAVAILABLE` 并附带 runner 的 stderr 行，后台任务盖章 `sandbox.runnerFailed` 并渲染自己的标记。损坏的沙箱永远不会被读作失败的命令，且命令永远不会无约束运行。
+- **在没有后端的平台上会发生什么——今天的 Windows？** `confine()` 抛出失败关闭的 `SANDBOX_UNAVAILABLE`，命令永不 spawn；`win32` 是保留的空链，由测试固定为同样失败关闭，直到 Windows runner 填充它（§ 延迟阶段）。
+- **`bwrap` 已安装在我的主机上但不可用（禁用了非特权 userns、LSM 拒绝 `mount`）——会发生什么？** 链探测是功能性的——它构建并强制一个真实 profile 而非检查 `--version`——因此存在但不可用的 `bwrap` 探测失败，选择落到注册表安装的 Landlock launcher，结论在提供方生命周期内缓存。
+- **沙箱限制网络或进程可见性吗？** 不——`SandboxMode` 仅声称文件操作；bwrap profile 刻意不 unshare pid，没有后端声称网络。网络限制是否成为自己的旋钮留在 § seam 中开放。
+- **哪些工具实际在约束下运行？** 通过 `ctx.bash` 的 OS 子进程——bash 工具及传递性的钩子命令——再加上通过沙箱化 `ctx.fs` 提供方运行的文件系统工具（`read`/`write`/`edit`，见[跨工具族 fs 沙箱 Agent Note](2026-07-14-cross-family-fs-sandbox.md)）：bash 通过 OS runner 约束，fs 通过进程内路径围栏约束，二者都以同一个 `ctx.sandboxPolicy` 模式为键。web/todo 仍在进程内且不受限制（web 的唯一效果是网络，不在文件效果模式词汇内）。
+- **授权的升级会持久化吗？** 不会。授权由发起请求的确切前台或后台调用消费；每个相邻调用保留自己的有效模式。后续的后台拒绝通过 `task_output` 呈现，并且可以作为一次新的精确命令重试的依据。
+- **运行时模式切换何时生效？** 一旦其会话事件提交，紧接着的下一次能力解析就会折叠并盖章新模式。模型不被告知常驻模式；其下一个命令直接在新策略下运行，任何拒绝都会在使用点命名该策略。
+- **重启后什么存活——如果运维人员在进程停止期间改了配置默认值呢？** 覆盖从会话日志回放（`effective = fold ?? config`），因此恢复的会话以零追赶机制保持其模式；离线漂移的默认值以与切换相同的方式改变行为（批准策略因被声明，还额外以运维人员/配置归因叙述）。
+- **结果上的 `enforcement: 'partial'` 是什么意思？** 所选后端强制其内核 ABI 管控的子集——例如 ABI v3 之前的 Landlock 不管控路径 truncate——并以结构化方式如此声明而非拒绝主机；探测的报告行区分各种情况。bwrap 和 Seatbelt profile 构造上管控所有承诺的文件操作，因此始终报告 `full`。

## Problem
The harness had no way to consume tools from the MCP (Model Context Protocol) ecosystem. MCP is the emerging standard for tool servers — GitHub, filesystem, databases, code search, and hundreds of community servers expose tools via MCP. Users want to point the harness at one or more MCP servers and have their tools appear as native model-facing tools, without writing per-server glue code.

2. Listen for `notifications/tools/list_changed` → re-run the same sync (dispose previous generation, register new). Deterministic names mean unchanged tools keep their names across re-syncs.

+# Agent Note: MCP 客户端插件——连接外部 MCP 服务器并桥接其工具
+
+Status: implemented
+
+[English](2026-07-07-mcp-client-plugin.md) | 中文
+
+## 问题
+
+harness 此前无法消费 MCP（Model Context Protocol）生态中的工具。MCP 是工具服务器的新兴标准——GitHub、文件系统、数据库、代码搜索以及数百个社区服务器都通过 MCP 暴露工具。用户希望将 harness 指向一个或多个 MCP 服务器，让其工具以原生的模型可见工具形式出现，而无需为每个服务器编写胶水代码。
+
+`ToolRegistry` 已经接受原始 JSON Schema 工具定义（`dsh-tools` README 中有记录：「Raw JSON-Schema tool definitions (from MCP servers) are still accepted by `ToolRegistry.register()` directly」），扩展实操手册（cookbook）也勾勒了预期模式（「MCP | one plugin per server: discover tools → `ctx.tools.register()`」）。基础设施已就绪，缺的是桥接插件。
+
+## 决策
+
+### 包
+
+单个包（package） `@deepseek-ai/dsh-mcp-client`，位于 `packages/mcp/mcp-client/`。不做能力 seam 的三包拆分——可预见范围内不会有第二种 MCP 客户端实现，且约定是「不要预防性拆分」（[能力 seam Agent Note](../architecture/2026-06-13-capability-seams.md)）。
+
+### SDK
+
+使用官方 [`@modelcontextprotocol/sdk`](https://github.com/modelcontextprotocol/typescript-sdk)（`Client`、`StdioClientTransport`、`StreamableHTTPClientTransport`）。harness 不自行实现 JSON-RPC，与 ACP 委托给 `@agentclientprotocol/sdk` 的做法一致。
+
+### 范围
+
+仅 MCP Client（不含 server 端——ACP 已承担「将 harness 暴露为 agent」的角色）。仅桥接 **Tools**——Resources 和 Prompts 延后处理（它们需要 harness 侧尚不存在的消费机制，且设计空间较大）。
+
+### 插件形态
+
+命名空间插件（具名导出 `name`/`inject`/`Config`/`apply`，无 `export default`）。`inject: ['tools']`。每个 MCP 服务器对应 `cordis.yml` 中的一个插件实例——同一个包以不同配置加载 N 次，与 `dsh-tool-subagent` 相同。
+
+### 配置
+
+以 `transport` 字段为判别的扁平联合类型：
+
+```typescript
+interface StdioConfig {
+ transport: 'stdio'
+ serverName: string // required namespace, ^[A-Za-z0-9_-]{1,32}$
+ command: string
+ args?: string[]
+ env?: Record<string, string>
+ cwd?: string
+ toolCallTimeoutMs?: number // default 60_000
+}
+
+interface StreamableHttpConfig {
+ transport: 'streamable-http'
+ serverName: string // required namespace, ^[A-Za-z0-9_-]{1,32}$
+ url: string
+ headers?: Record<string, string>
+ toolCallTimeoutMs?: number // default 60_000
+}
+
+type Config = StdioConfig | StreamableHttpConfig
+```
+
+`serverName` 是稳定的本地标识，用于在模型可见名称（见下文）中为该服务器的工具提供命名空间。它有意设计为用户配置，而非远端的 `serverInfo.name`：远端名称是不可信输入、跨部署不唯一（同一服务器的生产和预发布实例报告相同名称）、且可能在服务器升级时变化——这些都不得静默重命名模型可见工具。多个活跃实例使用重复的 `serverName` 属于配置错误：后加载的实例在启动时以可操作的错误消息失败，绝不静默覆盖或跳过。短 `serverName`（如 `gh`）也是缩短公开名称的调节手段。
+
+`cordis.yml` 用法示例：
+
+```yaml
+- id: mcp-github
+ name: '@deepseek-ai/dsh-mcp-client'
+ config:
+ serverName: github
+ transport: stdio
+ command: npx
+ args: ['-y', '@modelcontextprotocol/server-github']
+ env:
+ GITHUB_TOKEN: !!js process.env.GITHUB_TOKEN
+
+- id: mcp-web
+ name: '@deepseek-ai/dsh-mcp-client'
+ config:
+ serverName: web
+ transport: streamable-http
+ url: http://localhost:3000/mcp
+ headers:
+ Authorization: !!js `Bearer ${process.env.MCP_TOKEN}`
+```
+
+模型看到的是 `mcp__github__create_issue`、`mcp__github__search_code`、`mcp__web__search`。
+
+### 生命周期
+
+启动时从 `cordis.yml` 加载。HMR（热模块替换）（`@cordisjs/plugin-hmr`）提供热替换：编辑 yml 条目触发旧实例的 dispose（资源释放）（断开连接、注销工具），并创建新实例（连接、发现、注册）。目前不提供运行时动态 API。公开名称是 `(serverName, rawName)` 的纯函数，因此保持 `serverName` 不变的 HMR 替换会重建完全相同的模型可见名称——会话历史和权限规则保持有效——而添加或移除不相关的服务器永远不会重命名已有工具。
+
+### 工具发现与注册
+
+每个 MCP 工具有两个名称：
+
+- `rawName`——MCP `Tool.name` 的原始值，仅用于协议通信（`tools/call`）。
+- `publicName`——在 `ToolRegistry` 中注册的全局唯一模型可见名称：
+
+ mcp__<serverName>__<rawName>
+
+这种按服务器限定的形式是多服务器 agent 客户端的事实标准——所有被调研的终端用户产品都按服务器限定 MCP 工具名（[Claude Code](https://code.claude.com/docs/en/agent-sdk/mcp#tool-naming-convention) `mcp__github__list_issues`、[Codex](https://openai.com/index/unrolling-the-codex-agent-loop/) `mcp__weather__get-forecast`、[Gemini CLI](https://geminicli.com/docs/tools/mcp-server/#3-tool-naming-and-namespaces)、[VS Code](https://github.com/microsoft/vscode/blob/ab9ec62c6a61e429a9abd612ff220c3f4834c9ea/src/vs/workbench/contrib/mcp/common/mcpServer.ts#L217-L260)、[Cline](https://github.com/cline/cline/blob/52fdbb1d72f7324a28142a7ba7678d4b53c902f4/sdk/packages/core/src/extensions/mcp/name-transform.ts#L20-L35)、[Roo Code](https://github.com/RooCodeInc/Roo-Code/blob/b867ec9145750d0ae1ff7f02d35406e9bf2a0b16/src/utils/mcp-name.ts#L117-L140)、[Goose](https://github.com/block/goose/blob/b3a012cbdde854b0fe14f95b1c48543bf6517c0a/crates/goose/src/agents/extension_manager.rs#L1391-L1441)、[OpenCode](https://github.com/anomalyco/opencode/blob/d199b1bff90282a4f9cd6251b5fc7b16875a52f6/packages/opencode/src/mcp/catalog.ts#L117-L120)）；`mcp__<server>__<tool>` 的拼写方式与 Claude Code 和 Codex 一致。`mcp__` 前缀将 MCP 注册与原生工具的命名空间隔离，并为权限/遥测规则提供稳定的匹配模式（`mcp__*`、`mcp__github__*`）。
+
+1. 连接时：遍历 `client.listTools()` 的分页结果，推导每个工具的 `publicName`，然后通过 `ctx.tools.register()` 将其注册为原始 `ToolDefinition`。MCP 的 JSON Schema 和描述原样透传（不做 `defineTool` DSL 转换）；仅替换模型可见的 `name`。
+2. 监听 `notifications/tools/list_changed` → 重新执行同步（dispose 上一代、注册新一代）。确定性命名意味着未变化的工具在重新同步后保持原名。
+3. 执行器闭包持有 `rawName`；公开名称永远不发送给服务器，也永远不被解析以还原原始名称。
+4. 无 `presentCall`/`presentResult`——UI 消费方使用提供方无关的通用卡片兜底。
+5. 工具在系统提示词中是透明的——除名称本身外不附加「[via MCP]」标注。
+
+### 公开名称规范化
+
+MCP 允许工具名最长 128 字符且可包含 `.`；DeepSeek 的函数名契约允许 `[A-Za-z0-9_-]` 且最多 64 字符。公开名称按确定性规则规范化：非法字符替换为 `_`，当替换或截断改变了名称时，追加 `(serverName, rawName)` 标识的 12 位十六进制 SHA-256 hash，确保不同的 MCP 标识永远不会坍缩为同一个公开名称：
+
+```typescript
+function publicToolName(serverName: string, rawName: string): string {
+ const joined = `mcp__${serverName}__${rawName}`
+ const normalized = joined.replace(/[^A-Za-z0-9_-]/g, '_')
+ if (normalized === joined && normalized.length <= 64) return normalized
+ const hash = sha256(`${serverName}\0${rawName}`).slice(0, 12)
+ return `${normalized.slice(0, 64 - 13)}_${hash}`
+}
+```
+
+### 名称冲突处理
+
+MCP 仅保证工具名在[单个服务器内](https://modelcontextprotocol.io/specification/2025-11-25/server/tools#tool-names)唯一；跨服务器冲突是常态而非例外（一项[微软研究院调查](https://www.microsoft.com/en-us/research/blog/tool-space-interference-in-the-mcp-era-designing-for-agent-compatibility-at-scale/#namespacing-issues-and-naming-ambiguity)覆盖 1,470 个服务器，发现 775 个冲突的工具名；仅 `search` 就出现在 32 个服务器中，官方 GitHub 服务器发布的是裸名 `create_issue`）。始终启用的命名空间从结构上杜绝冲突，而非在冲突发生时再处理：
+
+- 两个服务器都发布 `search` → 共存为 `mcp__github__search` 和 `mcp__web__search`。
+- 名为 `search` 的原生 harness 工具不受影响。
+- 重复的 `serverName` 配置使后加载的实例在启动时失败（见配置一节）。
+- 服务器列出重复的工具名属于无效工具列表：同步抛出异常，上一代注册保持不变。
+- 替换期间的注册表冲突只可能意味着外部工具占据了该服务器的 `mcp__<serverName>__` 命名空间：部分代注册被回滚（该服务器零工具），并以醒目日志记录错误。
+
+工具永远不会被静默跳过；哪些工具可用永远不取决于插件加载顺序。
+
+### 命名不变式
+
+1. 每个 MCP 工具拥有稳定标识 `(serverName, rawName)`；每个活跃标识恰好对应一个公开名称。
+2. 公开名称是确定性的、全局唯一的，且满足 DeepSeek 64 字符 `[A-Za-z0-9_-]` 契约。
+3. MCP `tools/call` 始终接收原始的 raw name。
+4. 连接、断开或重新同步不相关的服务器永远不会重命名已有工具。
+5. 注册顺序永远不决定哪个工具可用。
+
+### 工具执行
+
+为来自同一个 MCP 服务器的所有工具提供统一的 `execute` 处理器：
+
+1. 解析 `rawName`（执行器闭包持有它），以配置的超时时间调用 `client.callTool({ name: rawName, arguments }, { signal: exec.signal })`——公开名称永远不发送给服务器。
+2. 映射结果：
+ - 多个 `text` 内容块 → 以 `'\n'` 连接为单个 `TextBlock`（必要原因：`flattenText` 使用 `join('')` 无分隔符，多块会丢失块间边界）。
+ - `image` 内容块 → 丢弃并 `ctx.logger.warn`（harness 没有图片内容块类型；[删除图片 Agent Note](../simplification/2026-07-04-drop-image-content-block.md)）。
+ - `isError: true` → 映射到 harness 的 `isError` 结果路径（`{ content: [...], isError: true }`）。
+3. 取消：`exec.signal`（来自 agent loop（智能体循环）的取消）透传给 MCP SDK 的 `callTool`，后者向服务器发送 `$/cancelRequest`。
+
+### 子进程环境（stdio 传输）
+
+复用 `dsh-subagent-acp` 的 `buildChildEnv` + `SENSITIVE_ENV_PATTERN` 清洗逻辑：过滤环境变量（剥离匹配 `/KEY|SECRET|TOKEN/i` 的凭证形变量），然后将 `config.env` 覆盖合并到顶层。显式配置的 env 不受清洗影响。
+
+### 断连 / 崩溃
+
+不自动重连。如果 MCP 服务器进程退出或传输层关闭：
+
+1. effect dispose → 所有已注册工具被注销（fiber 作用域的 disposer）。
+2. 后续模型对这些工具的调用 → `ToolNotFoundError` → `isError: true`。
+3. 恢复：用户编辑 `cordis.yml`（触发 HMR 重载）或重启 harness。
+
+这与 ACP subagent 模式一致：「崩溃即终态，报告错误，清理资源，不重试。」
+
+## 曾考虑的替代方案
+
+### MCP Server 端（将 harness 工具暴露给外部 MCP 客户端）
+
+延后。ACP 桥接已将 harness 暴露为 agent 服务器。再加一层 MCP server 会以不同协议重复这一功能，而用户的首要需求是消费外部工具，而非暴露自身工具。
+
+### 能力 seam 三包拆分（接口 / 实现 / 消费方）
+
+否决。可预见范围内不会有替代的 MCP 客户端实现——MCP 只有一个协议、一个 SDK。约定是「不要预防性拆分」，直到出现第二种实现。
+
+### 指数退避自动重连
+
+v1 否决。引入复杂性（工具已注册但暂时不可用的部分可用状态），且 stdio 进程崩溃通常表明配置问题，重试无法修复。HMR 已提供手动恢复路径。如有需要，可在未来作为 `reconnect: boolean` 配置项添加。
+
+### 桥接 Resources 和 Prompts
+
+延后。Resources 需要 harness 侧的机制来决定何时注入内容（系统提示词？按需？模型触发？）。Prompts 需要 harness 尚不具备的「提示词模板」概念。两者都需要独立设计；Tools 是高价值、低风险的起点。
+
+### 原始模型可见工具名加可选 `toolPrefix`
+
+否决。这是最初的提案，基于「大多数 MCP 服务器已在工具名中使用语义前缀（如 `github_create_issue`）」这一前提。该前提不成立：官方 GitHub 服务器发布的是 `create_issue`，参考文件系统服务器发布 `read_file`，Sentry 发布 `search_issues`——且上述微软调查表明冲突在生态规模下很常见。冲突时再加前缀（或 warn-and-skip）还会使可用工具集取决于插件加载顺序，且添加不相关服务器时工具可能被静默重命名——在对话中途使会话历史和权限规则失效。所有被调研的多服务器 agent 产品都不使用裸名。
+
+### 仅服务器命名空间（`github__create_issue`，无 `mcp__` 前缀）
+
+v1 否决。它能防止跨服务器冲突，但无法将 MCP 注册与原生 harness 工具分离，也丧失了 MCP 全局策略匹配模式（`mcp__*`）。前缀仅多花 5 个字符；`mcp__<server>__<tool>` 拼写与 Claude Code 和 Codex 一致，最大化模型的熟悉度。如果 ToolRegistry 未来引入源感知命名空间，届时可作为命名策略变更重新考虑去掉字面前缀。
+
+### 从服务器公告的 `serverInfo.name` 派生命名空间
+
+否决。远端名称不可信、跨部署不唯一、升级时可变；工具标识和权限规则不得静默跟随它。命名空间是本地配置。
+
+### 在工具结果中保留多个 TextBlock
+
+否决。DeepSeek 序列化器中的 `flattenText()` 在将 `ContentBlock[]` 扁平化为协议格式（wire format）时使用 `join('')`（无分隔符）。多个 text 块会静默丢失块间边界——这是正确性缺陷。所有现有工具返回单个 TextBlock；MCP 桥接遵循同一做法。
+
+## 测试
+
+覆盖率按层级命名；每个行为放在能表达它的最低成本层级。
+
+- **单元测试**（`tests/mcp-client.spec.ts`、`tests/apply.spec.ts`，mock MCP SDK）：`publicToolName` 算法（干净名称、规范化、截断加 hash、确定性、不同标识的分离）、raw 与 public 的协议纪律、跨服务器与原生工具共存、重复 `serverName` 加载失败与预留释放、无效工具列表拒绝、代切换/回滚、重新同步失败时的保留、结果映射、取消、配置 schema 校验。100% 逐文件覆盖率门禁约束该包。
+- **E2E**（`tests/mcp-client.e2e.ts`，无需密钥）：使用真实 MCP 协议对接仓库内的 fixture（测试前置数据）服务器、`@modelcontextprotocol/server-everything` 和 `@modelcontextprotocol/server-filesystem`（stdio 传输），以及进程内 `StreamableHTTPServerTransport` 服务器（Streamable HTTP 传输）——命名空间下的发现、带点号名称的端到端规范化、执行往返、重复 `serverName` 拒绝、dispose。
+- **快照**：刻意不做。MCP 工具不引入新的展示形态——它们以原始 `ToolDefinition` 注册，UI 消费方使用各自展示测试套件已固定的通用卡片兜底。将 MCP 服务器添加到某个可运行的快照组合会改变其已固定的系统提示词 fixture，且使每次回放依赖于 spawn 外部 MCP 服务器进程，而新增行为为零。如果后续变更为 MCP 工具引入专属渲染意图，该变更届时自行声明快照覆盖。
+
+## 后果
+
+- 每个 MCP 服务器只需 `cordis.yml` 中的一条配置即完成集成：`serverName: filesystem` 加一条 stdio 命令（或一个 Streamable HTTP URL），就能将 `mcp__filesystem__read_file` 放入模型的工具列表，可调用，协议上使用原始的 `read_file`。
+- 公开名称是会话历史和权限/配置表面的一部分；命名算法是由测试固定的 v1 契约，发布后变更即为破坏性变更。
+- `mcp__<serverName>__` 限定符在每个名称上消耗 token。已接受：描述和 JSON Schema 在工具定义 token 中占主导，而限定符换来了稳定标识、冲突隔离和 MCP 全局策略匹配模式（`mcp__*`、`mcp__github__*`）。
+- **MCP SDK 稳定性**：`@modelcontextprotocol/sdk` 仍在演进中；破坏性变更需要更新桥接。版本已固定，且该 SDK 被广泛采用（Claude Desktop、Cursor、VS Code），因此破坏性变更不太可能悄然发生。
+- **工具 schema 质量**：MCP 服务器可能暴露描述不佳的工具（模糊的描述、不完整的 JSON Schema）。harness 原样透传——垃圾进垃圾出；这是服务器作者的责任，不是桥接的。
+- **Stdio 进程管理**：行为异常的 MCP 服务器如果忽略信号，可能卡住 dispose。Cordis fiber 的 dispose 有有界的完全停稳过程；卡住的传输层最终在框架层面超时。
+- 崩溃恢复是手动的（HMR 编辑或重启）——v1 已接受；`reconnect` 配置作为未来工作保持开放。

-> **Superseded vocabulary (2026-07-22):** [Collapse named session modes into plan mode](../simplification/2026-07-22-plan-specific-collaboration-state.md) replaces this note's generic `dsh-mode`, `mode/set`, definition map, and `ctx.modes` design with the current plan-specific `dsh-plan-mode`, `plan/mode`, `{ section }`, and `ctx.planMode` contract. The review, boundary, reconstructability, and sandbox-orthogonality decisions below remain in force; generic API examples are retained as the historical design this simplification removed.
-
-## Problem
-
-Before this change, the harness had no durable way to put one agent into a distinct working stance. Plan mode needs the agent to explore and design under planning guidance, produce a reviewable artifact, cross an explicit approval boundary, and restore that state across resume and fork without making the model-visible request diverge from the session log.
-
-The extension seams already supplied the surrounding pieces: [`system-prompt/assemble`](../../../../packages/core/system-prompt/README.md) shapes guidance per step and the shipped request is logged in `request/header*` events ([reconstructability](../../implemented/architecture/2026-07-05-reconstructable-requests.md)); [`ctx.userInteraction`](../../../../packages/ui/user-interaction/README.md) carries the approval question and corrective feedback ([ask-user precedent](../../implemented/feature/2026-06-25-ask-user-question.md)); `SessionEventMap` carries durable per-agent facts ([the `todo/write` precedent](../../implemented/feature/2026-06-29-todo-write-tool.md)). The missing piece was the named session state that joins those seams while leaving execution enforcement on the independent sandbox and approval axes.
-
-## Decision
-
-The deliverable is **plan mode**. It ships as the first **session mode** — a named, logged, per-agent COLLABORATION state: a mode definition is deployment-configured guidance the model sees, while the mode IN FORCE for an agent is session state folded from its log. Modes are one axis and the enforcement knobs — the sandbox mode, the approval policy — are others: they never read or write each other, matching how Codex keeps its Plan/Default collaboration presets separate from its sandbox and approval settings. One new product package, `@deepseek-ai/dsh-mode` at `packages/mode/mode/`, owns the event vocabulary, a thin `ctx.modes` service, and every listener; the loop does not change. `plan` is the only required definition — the mode-shaped vocabulary exists so a second mode never renames durable event types, not because more modes ship now.
-
-The state is one `SessionEventMap` member: **`mode/set`**, a log-only, non-surface event carrying `{ mode: string }` with whole-value-replace semantics, plus a pure `foldMode(events)` that returns the mode in force — the last `mode/set`, or the default mode when none exists. Because [the log is the fact channel](../../implemented/architecture/2026-06-30-event-domain-semantics.md), resume, fork, and compaction restore the mode with no extra machinery, and UIs read flips off `session/event`. The default mode is the absence of mode guidance — no section, filtering, or gate. Loading `dsh-mode` still contributes one stable `exit_plan_mode` schema in every mode; that fixed cost avoids tool-catalog churn at mode boundaries.
-
-A mode's whole surface is soft: a `mode:policy` prompt section renders the active definition's guidance, while `exit_plan_mode` remains in the registered tool catalog across every mode and rejects at execution unless the folded mode is `plan`. A transition therefore changes only the system-prompt portion of the attributable `request/header` on the next step, keeping [reconstructability](../../implemented/architecture/2026-07-05-reconstructable-requests.md) green without changing native schemas or Code Mode's SDK. A mode deliberately enforces NOTHING: no execution gate, no tool filtering, no reach into the sandbox or approval knobs — a user who wants a hard read-only floor while planning switches the sandbox-mode option beside the mode picker, in either order, and neither axis disturbs the other. There is likewise NO per-mode tool allow/deny list — which tools a mode admits is an effects question, parked until tool definitions declare their effects ([Deferred](#deferred)); a mode's restraint is its section's guidance plus the exit review.
-
-The model leaves plan mode through the **`exit_plan_mode`** tool: its single argument is the plan text, which makes the plan reconstructable from the log, and the tool conducts the review itself through the user-interaction seam — a question whose supporting detail carries the exact plan, with options and a free-text channel, not a bare permission — so an approval flips the logged mode back to the default, and a rejection becomes the corrective error carrying the user's feedback verbatim, which keeps the model planning with direction. A user flips the mode from any surface through `ctx.modes.set()`; the flip is applied at the next turn boundary (session events are turn-enclosed) and narrated to the model once, only when the model-visible state actually changed.
-
-## High-level API
-
-### A plan-mode session end to end
-
-The user switches the session to plan mode through the ACP mode picker or `/plan [message]` in a terminal front door, and from the next step every request ships the configured plan guidance section. When the optional message is present, that same command submits it into the affected step. The `exit_plan_mode` schema was already present in default and remains byte-identical.
-
-The model explores and designs; the section's guidance is what defers changes into the plan. The sandbox and approval knobs keep whatever the user set them to — a deployment (or user) that wants kernel-enforced read-only during planning pairs plan mode with the independent sandbox-mode option.
-
-When ready, the model calls `exit_plan_mode` with the plan markdown as its argument; the review question carries that exact markdown as supporting detail — approve, or keep planning, with free-text feedback welcome. A native call also renders the plan card; a Code Mode nested dispatch has no native card, so the review detail is the common presentation surface.
-
-On approve, the tool flips the logged mode back to the default: the next step drops the plan section while retaining the same tool catalog (the changed header is in the log), and execution tracking from there is already `todo_write`'s job. On keep-planning, the model receives a corrective error carrying the user's feedback text, revises, and re-presents.
-
-### Deployment configuration
-
-Mode definitions are validated plugin Config — per repo convention, changeable from `cordis.yml` with no code edit. The deployment must provide the complete `plan` section; the package embeds no model instructions. Additional modes use the same config map:
-
-```yaml
-- id: mode
- name: '@deepseek-ai/dsh-mode'
- config:
- modes:
- plan:
- section: |
- You are in plan mode: explore and design, then present the
- plan for approval through exit_plan_mode.
-```
-
-A definition is exactly `{ section }` — there is deliberately no per-mode tool list and no enforcement field ([FAQ](#faq)). Definition names use the lowercase slash-command subset `/^[a-z][a-z0-9_-]*$/u`; `default` is reserved (the absence of policy) and rejected as a key. An invalid name or unknown definition key — a `tools` list or an `access` cap included — fails validation at load; an unknown mode name fails loudly at `set()` time.
-
-### In the terminal
-
-Terminal front doors get one entry command per configured definition through the plugin-owned command registry (`@deepseek-ai/dsh-commands`): `dsh-mode` registers `/plan [message]` for the required definition and, for example, `/review [message]` when `review` is configured. Each command records its named switch; a non-empty optional message is trimmed and passed to `agent.steer()`, which places it in a running agent's next step or delegates to `send()` for a new idle turn. The command name and result stay out of model history, while that explicit message is logged as an ordinary user message under the selected mode. The synthetic `default` entry contributes no command. The exit review prompts right in the terminal with no new machinery: it is an ordinary user-interaction question, so it rides the composed user-interaction provider's prompt queue that `ask_user_question` already uses.
-
-### Over ACP
-
-The mode PICKER is this package's surface: `session/new`/`session/load` advertise `availableModes`/`currentModeId` from `ctx.modes` (consumed opportunistically via `ctx.get`, the `tool-bash` pattern), `session/set_mode` calls `set()` and notifies `current_mode_update` optimistically (the pending mode IS the user's selection; the logged `mode/set` follows at the boundary), and a `session/event` listener re-notifies on each logged flip that differs from the last sent. The exit tool reuses the user-interaction ACP provider's elicitation flow; its ACP mapping carries the review `detail` because Code Mode nested dispatches have no native plan card, while native calls may additionally stream the plan card. Individual environment knobs — sandbox mode, approval policy, the model — are NOT modes and belong to `session/set_config_option` ([FAQ](#faq)).
-
-### For agent creators
-
-`ctx.modes` is the whole programmatic surface: `list()` returns the configured definitions plus the synthetic `default` entry (for pickers), `get(agent)` returns the folded mode plus any pending intent, and `set(agent, mode)` validates the name against `list()`'s vocabulary and records the boundary-applied intent — `default` is always a valid target, so exiting a mode is the same call as entering one. There is no creation-time mode option — a caller selects through `set()` before the first turn, which flushes identically. There is no live `agent/*` mirror to subscribe: UIs read `mode/set` off `session/event`, per [event-domain semantics](../../implemented/architecture/2026-06-30-event-domain-semantics.md).
-
-## Detailed design
-
-### Vocabulary
-
-```text
-'mode/set': { mode: string } // SessionEventMap merge in dsh-mode: log-only, non-surface,
- // whole-value replace — the last one in the log wins
-DEFAULT_MODE = 'default' // the fold of a log with no mode/set; reserved, not definable
-```
-
-The payload carries no reason/provenance field: a tool-driven flip sits next to its `tool/call` in the log and a user flip sits at its turn boundary, so the cause is log-adjacent — the same "narrative fields are derivable" call the [reconstructability Agent Note](../architecture/2026-07-05-reconstructable-requests.md) made for request-header facts (the in-flight `env/state` event carries a `source` precisely because its drift variant has NO log-adjacent cause — a contrast, not a conflict). Mode names are config-declared vocabulary, not opaque cross-boundary ids, so they stay bare strings (no `Branded<B>`).
-
-### Config and the resolve step
-
-```text
-interface ModeDefinition { section: string } // prompt text — a mode's whole vocabulary
-interface ModeConfig { modes: Record<string, ModeDefinition> } // plan is required and owns its complete prompt
-resolveConfig(config): ResolvedModes // explicit resolve (the dsh-bash template), fail-loud:
- // missing plan, 'default', blank sections, and unknown keys rejected
-```
-
-The one-field shape is deliberate minimalism, not the final vocabulary: a per-tool policy dimension returns as effects metadata on tool definitions ([Deferred](#deferred)), read here rather than re-declared per mode — the config shape must not need a migration when it arrives.
-
-### The fold, the service, and the flush
-
-`foldMode(events)` is pure (exported for reconstructors and tests) and folds the append-only session log directly; `mode/set` is not a surface node, so compaction cannot shadow it. `set(agent, mode)` validates the name against `list()`'s vocabulary — the configured definitions plus the reserved `default`, which is rejected as a config KEY but always accepted as a `set()` TARGET — drops a no-op (target equals pending, else current), and otherwise records `{ mode, narrate }` in a `WeakMap` pending-intent slot. It cannot append immediately because [every session event is turn-enclosed](../../implemented/architecture/2026-06-15-turn-enclosure-invariant.md) and an idle agent has no open turn.
-
-Contained listeners on the loop's interception seams ([defensive patterns](../../../../docs/defensive-patterns.md): a policy plugin must not block a prompt or a turn) flush the pending intent as a `mode/set` append — `agent/prompt-submit` fires inside the just-opened turn before its first assembly, and `agent/turn-continuation` fires after an ordinary step closes before its successor. Automatic request recovery bypasses continuation, so a prepended `agent/request-error` wrapper delegates through the composed policy and asynchronous backoff, then flushes only a `retry` decision before the waterfall returns to the loop; an effect-scoped lifetime guard suppresses a captured wrapper that resumes after plugin disposal. All three paths sit outside tool execution and log publication (post-commit `session/event` observers are observe-only), so every step runs under the mode its assembly folded. When the flushed mode differs from the fold at the last `request/header`, the flush appends one coalesced `context/message` notice in the same frame ("The user switched this session to plan mode."); the user-visible narration cases are enumerated in the [FAQ](#faq).
-
-### The soft layer: a computed section and a stable exit schema
-
-The registered prompt section reads the calling agent's mode from `AssembleContext.agent` and resolves to the active definition's guidance or `''`. The loop renders per step and logs a complete `request/header` whenever the rendered header changes, so entering or leaving a mode is attributable. The section is static per mode and the plan itself stays in the conversation as messages and tool arguments; re-injecting separate plan state on every request ([Prior art](#prior-art)'s compaction-survival hack) is unnecessary prompt churn.
-
-The guidance contribution is `{ name: 'mode:policy', order: 50, text: context => … }`: after persona (0), before tool guidance (100–199), and empty for default or agent-less assembly. `exit_plan_mode` is registered once through `ctx.tools` and never filtered, so native schemas and Code Mode's generated SDK remain byte-identical across mode switches; a deployment without `dsh-mode` lacks that one binding. There is NO `tools/pre-execute` listener: a mode gates nothing, while the exit tool's own folded-mode check rejects out-of-plan calls. The exit review is a question with options and feedback, not a permission, so it lives inside the tool's execution over the user-interaction seam.
-
-### `exit_plan_mode`
-
-`defineTool` has one required `plan: string` argument. Native execution records it in the ordinary `tool/call`; Code Mode records the outer `run_code` source before execution and appends the normalized nested arguments in `tool/code-dispatch` after the dispatch settles. `execute` rejects an agent-less call (the [`todo_write` precedent](../../implemented/feature/2026-06-29-todo-write-tool.md)), rejects any folded mode other than `plan`, rejects an empty or heading-less plan before asking the reviewer, then conducts one single-select `ctx.userInteraction.ask()` review whose `detail` is the exact plan — approve or keep planning — with free-text feedback open. Only exactly one `Approve` selection consents; every other shape fails closed. Approval records a SILENT boundary-applied intent to switch to `default` and returns a short confirmation. The deployment guidance tells the model to make this the only and final tool call in its response; if a model violates that rule, the runtime still holds plan guidance for the rest of the batch, and the next step logs a changed header with the guidance removed and tool schemas unchanged. Every non-approval outcome returns a corrective `isError` and leaves the mode in `plan`.
-
-Its [render intent](../../implemented/architecture/2026-07-02-tool-render-intent-union.md), decided up front: `presentCall` is a `generic` card titled by the plan's first heading with the plan markdown as content, plus a `generic` result card. Native front doors show that card before the question; Code Mode nested dispatches do not produce native call-card events, so the user-interaction `detail` independently carries the same plan on every provider. The seam is consumed opportunistically (`ctx.get('userInteraction')`), so `dsh-mode` composes without it and degrades to the manual exit pinned in the [FAQ](#faq).
-
-### Dependencies and surfaces
-
-`dsh-mode` is one product package, not a capability-seam trio ([Alternatives considered](#alternatives-considered)): it peers on `cordis`, `dsh-session`, `dsh-agent`, `dsh-tools`, and `dsh-system-prompt`, injects `['tools', 'systemPrompt']`, and reads `ctx.userInteraction` opportunistically at execute time (a type-only peer edge on `dsh-user-interaction`); its only UI-facing edges are optional type-only peers (`dsh-commands` for the per-definition entry commands). Beyond the `ctx.modes` call surface everything participates through listeners, so dropping the package gracefully removes modes rather than breaking a consumer. Terminal front doors need no mode-specific code: `dsh-mode` itself registers each definition's command on the command registry when one is composed (an optional type-only peer edge on `dsh-commands`), and the exit review rides the composed user-interaction provider's prompt queue. The ACP wire mapping is pinned in [High-level API](#over-acp); package-wise the bridge takes a type-only peer edge on `dsh-mode` and reads the service opportunistically, so a bridge without the plugin behaves exactly as today.
-
-### The recorded scenario and the harness op
-
-`input.json` gains one step op, `{ "op": "setMode", "modeId": "plan" }`, driven through the real `session/set_mode` RPC, and a scripted `elicitationAnswers` queue. The `plan-mode` scenario enters plan before turn 1, runs a real `cat` under the independently configured sandbox, presents a plan through `exit_plan_mode`, receives scripted approval, then edits on the next step. The first `request/header` contains the full stable toolset plus the configured mode section; the post-approval changed header retains byte-identical tool schemas and removes only that section. `plan-mode-reject` pins corrective free-text feedback and the unchanged plan state. Both recordings replay host commands under Seatbelt or bwrap; backend-specific sandbox denial stays at the bash-tool unit tier.
-
-### The mechanical tail
-
-No new cordis event is declared (`mode/set` rides `session/event`; the listeners attach to existing waterfalls), so the events catalog is untouched. Regenerated in the same change: the persistence log catalog (`mode/set`), the services catalog (`ctx.modes`, JSDoc-complete), the config catalog (`ModeConfig`), the tool catalog (`exit_plan_mode`), the producer/consumer map and doc graphs, and the module graph. Repo plumbing: a root tsconfig `paths` entry, the new group's README plus a [packages map](../../../../packages/README.md) row (a new top-level group is the deliberate act that table names), an `architecture.md` capability-services row for `ctx.modes` (budget-checked), and the cookbook row upgrade.
-
-## Deferred
-
-Each behind its own decision: subagent mode inheritance via a forwarded creation-time mode option (removed as unconsumed; it returns with its first consumer), preset modes beyond `plan` (read-only, accept-edits), the idle-record primitive if pending-intent loss proves real, and — the big one — **effects self-declaration on tool definitions**: a per-tool read-only/mutating classification (the MCP `ToolAnnotations` vocabulary — `readOnlyHint`/`destructiveHint` — is the natural template, with its untrusted-hint caveat implying trust tiers). That item is what a general per-mode tool policy waits on: this Agent Note first shipped an interim per-mode name allowlist and removed it before release — a hand-maintained list mislabels the effects question, must track every tool a deployment composes, and rots silently as tools arrive — so mode-scoped tool availability (and per-tool `ask` policies) returns as a CONSUMER of declared effects, which is its restart trigger.
-
-The canonical [`examples/acp-agent`](../../../../examples/acp-agent/) composition mounts the mode and question-tool plugins on the full ACP coding server; plan mode is an additive session feature, not a second server profile. Its snapshot suite pins the plan-shaped initial header, a real read, scripted approval, stable tool schemas across the pure-removal header delta, a subsequent edit, rejection feedback, and the keyless mode wire. A self-skipping real-API smoke boots that same leaf, verifies the file before approving the review, and verifies the approved implementation afterward.
-
-## FAQ
-
-Behavioral clarifications of the chosen design; rejected designs live in [Alternatives considered](#alternatives-considered), accepted costs in [Consequences](#consequences).
-
-**When does a user's mode flip take effect?** At the next pre-assembly boundary: `agent/prompt-submit` covers the first step, `agent/turn-continuation` covers a normal successor, and the post-composed `agent/request-error` retry decision covers automatic recovery. A mode selected while a request or retry backoff is in flight therefore shapes the following model request. This is the "applies to subsequent requests" semantics every product in [Prior art](#prior-art) ships.
-
-**When is a mode change narrated to the model?** Only when the model-visible state actually changed: the flush compares the flushed mode against the fold at the last `request/header` and narrates once, coalesced. A net-zero flip sequence (plan then back, all before the boundary) narrates nothing; a tool-driven exit narrates through its own tool result instead; a mode set before the first turn narrates nothing — the section is the state statement. The principle is the in-flight env-state proposal's boundary narration: a silently flipped prompt surface leaves the transcript arguing from a state the header no longer has.
-
-**What happens on resume when the config no longer defines the folded mode?** A folded mode name the current config no longer defines behaves as the default mode without a notice, so the session neither gains a substitute restriction nor becomes unusable. `set()`'s loud validation covers only the write path; a resumed log answers to the config it finds.
-
-**What if a deployment composes no user-interaction provider?** Plan mode stays safe but manual: `ctx.userInteraction.ask()` throws `NO_PROVIDER` (and an absent seam never resolves at all), the tool returns the corrective `isError`, and the exit degrades to the user toggling modes — never to an unreviewed exit. The mode section tells the model to present its plan through `exit_plan_mode` — and to ask the user in prose if that fails — so it keeps presenting instead of stalling.
-
-**Why is there no per-mode tool allowlist?** Because "which tools are safe in a planning mode" is a property of each TOOL (its effects), not of the mode — a per-mode name list re-declares that fact in the wrong home, must enumerate every tool the deployment composes (MCP servers included), and rots silently as tools arrive. Until tool definitions declare their effects ([Deferred](#deferred), where the removed interim allowlist is archived with its restart trigger), a mode restrains by its section and the exit review; the exposure is an accepted cost ([Consequences](#consequences)).
-
-**Do subagents inherit the parent's mode?** A fork child inherits for free — the parent's `mode/set` is inside the seeded prefix. A spawn child starts in the default mode; a creation-time mode option and automatic forwarding by subagent providers are deferred together ([Deferred](#deferred)).
-
-**How does plan mode relate to the sandbox's read-only mode?** They are separate axes that never touch: the mode is the collaboration stance (a `mode/set` fold), the sandbox mode is an enforcement knob (a `bash/sandbox-mode` fold, [the sandbox Agent Note](2026-07-06-sandbox.md)) — plan mode neither reads nor caps it, exactly as Codex keeps its Plan/Default presets separate from its sandbox and approval settings. A user who wants kernel-enforced read-only while planning sets both: flip the mode picker AND the sandbox-mode option, in either order; each switch changes only its own fold, so there is no interference and no restore step to crash out of. The log attributes each axis to its own event — the stance to `mode/set`, the confinement to `bash/sandbox-mode`.
-
-**Why aren't sandbox mode, approval policy, or the model themselves modes?** They are individual environment knobs and belong to ACP's `session/set_config_option`; the division this proposal pins is picker-to-modes / knobs-to-config-options, recorded in [the feature matrix](../../../../packages/ui/acp/acp-feature-support.md) now that both this stack's picker and the sandbox stack's config options are landed. A mode definition may later bundle env facts (applied through `ctx.envState` where mounted) so a Codex-style preset stays a single mode; fusing approval policy into the mode CONCEPT itself is rejected in [Alternatives considered](#alternatives-considered).
-
-## Prior art
-
-A survey of shipped plan modes (Claude Code, Cursor, Copilot, OpenCode, Gemini CLI, Cline, Windsurf, Codex) shows the same five parts everywhere — the low-authority tool policy, plan artifact, approval moment, execution-state switch, and durable state that [Problem](#problem) builds on.
-
-The mode surface is a LIST everywhere it is advertised, never a boolean: Claude Code's picker offers `plan` beside `acceptEdits` (plus an auto-mode entry into plan), and Codex exposes `Plan` beside `Default` as collaboration-mode presets while keeping approval and sandbox settings separate. This is the surface [the ACP feature matrix](../../../../packages/ui/acp/acp-feature-support.md) records as the gap, and what sizes the vocabulary as named modes rather than a flag.
-
-The deployment-owned example prompt borrows the instrumental behavior, not product-specific mechanics. From Codex: remain in plan mode despite imperative implementation language, explore before asking, distinguish repository facts from user-owned choices, and make the plan decision-complete across APIs, data flow, failures, tests, and assumptions. From Claude Code: prohibit mutations and commits, prefer existing patterns, use questions only for requirements or approach choices, and finish through the exit tool rather than a prose approval request. It deliberately omits Codex protocol tags and Claude's plan-file or phased-subagent machinery because those belong to their runtimes, not this plugin contract.
-
-The ecosystems that leave modes to convention show the failure shapes to avoid. Pi-style mode extensions fight over a last-wins global active-tool list, enforce "read-only" by prompt text alone (a hallucinated call to a still-registered tool executes), and re-inject plan state into every request to survive compaction. The contested global list and the re-injection hack close structurally here — per-agent folded state, and a log-only non-surface event compaction cannot shadow. The prompt-only shape, by contrast, is deliberately KEPT — it is what Codex ships for Plan, and it is why the mode axis composes freely with the enforcement axes: a deployment that wants a hard floor pairs the mode with the independent sandbox knob instead of the mode carrying its own enforcement ([FAQ](#faq)).
-
-## Alternatives considered
-
-**Permission modes as the concept (the Claude Code shape).** One `permissionMode` fusing approval policy and tool policy. Here those are two axes with two owners: the approval seam owns "who answers this question", modes own "what surface does the model get". ACP models them as related but distinct (a mode may select an approval policy later — a mode definition gains a field, not a merger).
-
-**A capability-seam trio.** Interface/implementation/consumer fits a swappable backend; a mode's variable parts are config values, not implementations. Splitting would manufacture an empty implementation package — the same "don't split preemptively" call the approval seam and [`todo/`](../../implemented/feature/2026-06-29-todo-write-tool.md) made.
-
-**Loop-owned mode state.** Rejected on the standing rule (plugins, not loop changes): every hook the feature needs — assemble, pre-execute, turn boundaries, session events — is already a documented seam, so a loop edit would buy nothing but coupling.
-
-**A per-mode tool allowlist with a deny-by-default gate (the first shipped shape).** Removed before release. A hand-maintained name list re-declares a per-TOOL fact (its effects) per MODE: it must enumerate every tool the deployment composes — MCP servers and future registrations included — and it rots silently as tools arrive (a new read-only tool is blocked until someone edits every mode; the author burden lands on whoever knows the mode, not whoever knows the tool). It also over-promises: the list looks like a security boundary while the real boundary for anything non-shell does not exist. The general dimension is parked on effects self-declaration ([Deferred](#deferred)); the consequence — plan mode is guidance-only, the very Pi hole the gate once closed — is accepted deliberately, priced in [Consequences](#consequences).
-
-**An `access` sandbox cap on the mode (the second shipped shape).** Also removed before release. `ModeDefinition.access` clamped the bash seam's per-call sandbox resolution to a mode-declared ceiling (a `bash/resolve-mode` waterfall + ladder-min listener, with guards withholding bash under an unconfinable executor and denying escalation mid-mode). The state stayed orthogonal — the clamp never wrote the sandbox knob — but the AXES did not: entering plan changed what the sandbox enforced, fusing the collaboration stance with an enforcement level and contradicting the Codex-shaped separation the review converged on (Plan/Default presets never touch sandbox or approval settings). One user-visible symptom of the fusion: flipping the sandbox option to `workspace-write` while planning silently did nothing. The cap, the waterfall, and the mode→bash dependency edge were removed together; a deployment gets kernel-enforced read-only planning by pairing the mode with the independent sandbox-mode option, and a mode-triggered PRESET (a mode definition bundling suggested knob values, applied as ordinary knob switches) can return later without re-fusing the axes.
-
-**Runtime-only mode (UI- or bridge-local, unlogged).** Resume and fork would silently drop the mode, and the header deltas a mode causes would have no attributable cause in the log. Logged state is what makes the mode auditable and restorable for free.
-
-**Mode flips as `context/message` via `agent.inject()`.** Reuses an existing turn-enclosure path, but puts policy state into the model transcript — the model does not need to be told twice (the section already tells it), and a log-only fact should not occupy surface.
-
-**A plan-file store (`.plans/` directory).** A second durable home for what the log already carries replayably; a deployment wanting files can add a tool that writes them. One home per fact.
-
-**A boolean `planMode` instead of named modes.** Too narrow for the surface the repo already tracks: ACP advertises a mode LIST and the shipped pickers fill it with more than plan ([Prior art](#prior-art)); generalizing later would rename durable event vocabulary. The string-shaped mechanism costs nothing extra now; only `plan` ships as a definition.
-
-**A tool-policy-stack service (the Pi-critique remedy).** A dedicated composition service for tool policies is premature: this implementation performs no mode-scoped tool filtering, and future effect policies can compose through the existing guarded execution seams. Formalize only when declared tool effects create a concrete composition requirement.
-
-**Exit approval through the approval seam (a `{ kind: 'ask' }` gate decision).** The original sketch, natural while the approval seam was the only asking machinery in flight — but it seats a review in a permission chair: the seam's outcome vocabulary is deliberately closed and one-shot (`allowed-once`/`rejected`), so a rejection carries no feedback and an approval can never grow options (approve-and-accept-edits). The exit moment is a question, not a permission — the user-interaction seam gives it options plus the free-text channel, and the rejection feedback reaches the model verbatim. The approval seam remains the right seat for genuine permission gates (the sandbox escalation), and the registry's `ask` vocabulary stays available to deployments that want one there.
-
-**Exit by prose or steering instead of a tool.** No artifact and no approval moment — the tool's argument IS the reviewable plan, and its review question is what gives the human a structured yes/no attached to the exact transition.
-
-## Consequences
-
-What holds now, pinned by the unit, protocol, snapshot, and real-API tiers:
-
-- The mode in force is a pure function of the session log: resume and fork restore it with no extra machinery, and a `mode/set` is followed by a matching complete `request/header` on the next changed step.
-- A user-driven flip narrates exactly once at the next boundary and a net-zero flip sequence narrates nothing; a tool-driven exit narrates only through its tool result.
-- In default mode the plugin contributes no mode section but does contribute the stable `exit_plan_mode` schema; a deployment without `dsh-mode` lacks that binding.
-- Native tool schemas and Code Mode's SDK stay byte-identical across default, plan, and custom-mode transitions; only the configured guidance section changes.
-- Plan mode changes nothing on the enforcement axes: the toolset, the sandbox mode, escalation, and the approval policy behave identically in plan and default — pairing the mode with the independent sandbox/approval knobs is how a deployment hardens planning.
-- Mode definitions are changeable from `cordis.yml` with no code edit; the complete plan instructions are required there, while missing plan config, malformed definitions, and unknown keys fail at load and unknown mode names fail at `set()`.
-- `exit_plan_mode` is always advertised, rejects outside plan, drops only plan guidance after approval, and carries keep-planning feedback in a corrective `isError`; ACP mode updates and each surface's user-interaction provider carry the human side.
-- The docs tail shipped with the landing: READMEs, regenerated catalogs (persistence log, config, cordis services, tools), the packages map and architecture rows, and the cookbook row.
-
-The accepted costs: a pending user flip set while idle is lost if the process dies before the next turn (the UI re-applies; the idle-record primitive is the escape hatch if this bites in practice). A mode transition changes the system prompt at order 50, so the cache path from that point onward changes, but the tool schemas and Code Mode SDK no longer churn. **A mode restrains by guidance alone**: a model that ignores the section CAN mutate during plan — the review moment, the session log, and independent sandbox, approval, and filesystem policies are the containment surface. Hardening planning means setting those knobs, not widening the mode; the removed enforcement shapes and their effects-declaration restart trigger remain in [Alternatives considered](#alternatives-considered) and [Deferred](#deferred). The ACP mode surface carries the picker while sandbox, approval, and model selectors remain config options under the division pinned in the [FAQ](#faq) and [feature matrix](../../../../packages/ui/acp/acp-feature-support.md). If ACP removes session modes in favor of config options, the picker mapping can migrate without changing the logged mode state or model surface.

## Problem
A plugin often owns a session-stable opener the model must always see — a skills catalog, an AGENTS.md digest, a workspace baseline. Before this seam the harness offered two homes, and both are wrong for that content. The system prompt is one rendered string: message-shaped content (a user-role `<system-reminder>` envelope, a multi-message primer) does not fit it, and providers weight conversation messages differently from system text. Durable history (`agent.inject()`, a `context/message` at session start) makes the opener permanent: every `deriveMessages()` consumer replays it, the compaction retention walk owns it, forks bake it in stale, and a resume cannot refresh it — a catalog captured at session birth outlives the world it described.

+# Agent Note: 会话前缀——派生历史之前的仅请求消息
+
+Status: implemented
+
+[English](2026-07-07-session-prefix.md) | 中文
+
+## 问题
+
+插件经常拥有一段会话级别稳定的开场内容，模型必须始终看到它：技能目录、AGENTS.md 摘要、工作区基线。在引入本 seam 之前，harness 为这类内容提供了两个归属位置，但两者都不合适。系统提示词是一个渲染后的单一字符串：消息形态的内容（user 角色的 `<system-reminder>` 信封、多消息引导序列）放不进去，而且提供方对会话消息和系统文本的权重处理不同。持久化历史（`agent.inject()`、会话启动时的 `context/message`）使开场内容变为永久：每个 `deriveMessages()` 消费方都会回放它，压缩（compaction）的保留遍历拥有它，fork 会将其以陈旧状态固化，恢复也无法刷新它——会话诞生时捕获的目录会比它所描述的世界活得更久。
+
+显而易见的第三种选项——让插件在请求发出途中编辑 `messages`——被[可重建请求 Agent Note](../architecture/2026-07-05-reconstructable-requests.md)禁止：每个由循环构建的请求都是会话日志的纯函数，因此无论哪个通道承载开场内容，都必须精确记录它所发送的内容。缺失的是一个带有持久记录的仅请求消息通道。
+
+## 决策
+
+`agent/session-prefix` 是 agent 事件映射上的一个 waterfall（瀑布式事件）（[`packages/core/agent/src/types.ts`](../../../../packages/core/agent/src/types.ts)）：监听器接收一个冻结的空种子并返回扩展（规范的贡献方式是前置插入 `[mine, ...await next()]`，在协议格式上产生注册顺序）。agent loop（智能体循环）（[`packages/core/agent-loop/src/loop.ts`](../../../../packages/core/agent-loop/src/loop.ts)）在每个循环实例中触发一次，惰性地在实例首次 `agent/pre-step` 之前执行；组合后的列表被深拷贝、深冻结、缓存在实例上，并在该实例发出的每个请求中置于整个派生历史之前——紧接在提供方的 system 槽位之后（[协议格式顺序](../../../../docs/core-data-structures/core.md#the-request-envelope-llmcallconfig-and-the-logged-header)）。
+
+三个属性承载了这一设计：
+
+- **仅请求，记录在 header 中。** `deriveMessages()` 从不返回前缀；它唯一的持久记录是实例锚定的 `request/header` 快照上的 `EpochHeader.messagePrefix`——可重建请求 Agent Note 已为请求的非历史部分拥有的通道，因此不引入新的会话事件。配套的 [`dsh-agent-loop/invariant`](../../../../packages/core/agent-loop/src/invariant.ts)对每个循环构建的请求重新计算 `messagePrefix + boundary derivation`；启用该贡献时，未记录的前缀无法到达协议格式。
+- **按实例冻结。** 复用是结构性的，而非靠纪律保证：缓存的产物在会话中途不可变，因此提供方的提示词缓存从构造上成立，前缀以每步零边际成本扩展了可缓存区域。进程重启或 `ctx.agents.resume()` 产生新实例：它重新组合，任何漂移都可追溯地落在 `'resume'` header 快照上。这就是本 seam 创建的路由规则：会话冻结的开场内容走前缀；会话中途变化的内容走仅追加历史通道（`agent.inject()` 或工具/prompt-submit 的 `additionalContexts`——[拦截 seam Agent Note](2026-06-30-interception-seams.md)），每条都是一次性支付的持久 `context/message`，之后被前缀缓存覆盖。
+- **在持久请求信封中保持精确。** 组合先于实例的首次 `agent/pre-step` 和请求边界。第一个已路由请求会把当前前缀记录在其 header 上，因此步骤后的 token 压力会将精确前缀与实际提示词、工具和已路由模型一起读取；通用的步骤前检查点 seam 不携带压缩专属参数。被取消/dispose 中断的组合会被丢弃，永不缓存：感知中止的监听器的降级回退不会泄漏到后续请求中，下一轮次在活信号下重新组合。
+
+由于组合在边界快照之前运行，组合监听器的会话追加会加入当前请求的派生历史。压缩在结构上不可能触及前缀（或系统提示词）：它重写的是表面节点，而 header 状态从不进入表面。
+
+## 测试
+
+[拦截测试](../../../../packages/core/agent-loop/tests/interception.spec.ts)固定了以下行为：没有变更 header 时的组合一次复用、前置插入顺序、空前缀省略、不可变性、组合在步骤前检查点之前完成，以及已路由 header 上的前缀；[取消测试](../../../../packages/core/agent-loop/tests/cancel.spec.ts)固定了丢弃与重新组合。Session、不变式、token-meter 和压缩测试覆盖 header 往返、请求重建与持久前缀感知的压力核算。快照归一化保留前缀计数，[固定 header 场景](../testing/2026-07-06-pin-request-header-content-in-one-scenario.md)拥有内容，默认示例保持无前缀。与提供方无关的 seam 无需专门 e2e；带密钥的 [request-cache e2e](../../../../packages/core/agent-loop/tests/request-cache.e2e.ts) 覆盖了其缓存经济性。
+
+## 曾考虑的替代方案
+
+- **每请求 `before`/`after` 槽位，每步重新计算**（最初提出的形态：一个每请求触发的 waterfall，贡献冻结的 `before` 消息置于历史之前、新鲜的 `after` 消息置于历史之后）：否决。每步重新组合 `before` 会引入漂移，必须记录为完整的变更 header；`after` 槽位位于不断增长的历史之后，其 token 在每个请求中重复支付，且其后的所有内容不可缓存。对照各替代方案衡量，当前所有更新模式都能通过持久追加更廉价地满足（支付一次，此后缓存读取），而唯一没有归属的内容是会话稳定的开场——它需要的是冻结，而非重新计算。
+- **系统提示词分段**（`system-prompt/assemble`）：对此类内容否决。assembly 渲染为单一 `system` 字符串，消息形态的开场放不进去；且系统提示词被设计为每步重新组装（变化时带完整的变更 header），而开场内容需要按实例冻结的语义。
+- **持久化历史开场**（会话启动时 `inject()`）：否决。永久历史正是问题陈述中的失败模式——到处被回放、可被压缩、在恢复后仍保持陈旧状态。
+- **按轮次组合而非按实例组合**：否决。轮次边界的重新组合要么与日志静默失同步，要么强制产生变更 header；且它每次触发都会破坏提供方缓存。合理的刷新点是实例边界，`'resume'` 快照已在那里可追溯地记录漂移。
+- **通过 `agent/pre-step` 携带提示词/前缀，用于临时压力估算**：否决，因为它把通用生命周期 seam 耦合到一个消费方，而且仍会遗漏更晚的请求路由和工具；步骤后的回放会从持久的已路由 header 读取请求信封的每个字段。
+- **专用会话事件承载前缀**：否决。header 事件按设计就是请求的非历史记录；第二个事件会为同一事实提供第二个归属，并多出一个需要保持完整的编解码器。
+
+## 后果
+
+- `agent/pre-step` 保持通用的 `(agent, turn, step, signal)` 检查点。压缩不接收 prefix 参数；`ctx.tokenMeter` 在步骤后从规范的已路由 header 折叠前缀。
+- 贡献者的内容在会话中途变化时，直到下一个实例才会被重新读取——这是设计意图。需要会话中途目录更新的部署，应将变更通知路由到仅追加历史通道，支付一条持久 `context/message`。
+- 被放弃的 `after` 槽位意味着请求尾部附近没有仅请求通道；仓库中没有任何功能需要它，且恢复它会重新引入本设计旨在避免的每步重复支付成本。
+- 空组合即为规范缺失：无贡献者的部署不记录额外的 header 字节，其请求就是裸派生。

## Problem
A model stuck in a loop re-issues the same tool call with byte-identical arguments — re-running a failing grep, re-reading an unchanged file, polling a command that already gave its answer — and each round trip burns tokens, wall-clock, and (for paid APIs) money without adding information. The harness has nothing that notices: the loop has no step budget, no plugin tracks call repetition, and the model only escapes when it happens to vary its own behavior. The failure mode is real and cheap to detect — [pi-repeat-tool-guard](https://github.com/Kingwl/pi-repeat-tool-guard) ships exactly this as a pi coding-agent extension: count consecutive identical calls and, past a threshold, append a `<system-reminder>` telling the model to stop repeating itself and change course.

+# Agent Note: 重复工具调用守卫插件
+
+Status: implemented
+
+[English](2026-07-08-repeat-tool-guard.md) | 中文
+
+## 问题
+
+模型陷入循环时，会以字节级相同的参数反复发起同一个工具调用——重新运行一条失败的 grep、重新读取一个未变化的文件、轮询一条已经给出答案的命令——每一轮往返都消耗 token、挂钟时间以及（对付费 API 而言）金钱，却不带来新信息。harness 目前没有任何机制能察觉这一点：循环没有步骤预算，没有插件追踪调用重复，模型只有在碰巧改变自身行为时才能跳出。这种失败模式真实存在且检测成本极低——[pi-repeat-tool-guard](https://github.com/Kingwl/pi-repeat-tool-guard) 正是以 pi coding-agent 扩展的形式提供了这一功能：统计连续相同调用次数，超过阈值后追加一条 `<system-reminder>` 告诉模型停止重复并换个方向。
+
+harness 已经具备 pi 扩展所使用的全部 seam，而且更好：[拦截 seam Agent Note](2026-06-30-interception-seams.md)赋予 `tools/post-execute` 一种经过认可的方式，将面向模型的上下文附加到已完成的调用上；循环缓冲并注入该上下文，同时保持调用/结果的邻接关系；注入的上下文是一条已记录的 `context/message`——因此原生守卫无需新增会话事件即可满足「模型可见 ⟺ 已记录」规则。缺少的只是插件本身。
+
+## 决策
+
+该守卫是一个循环卫生插件，而非面向模型的工具。它统计对同一工具以相同规范化参数发起的连续调用次数，并在配置的阈值处注入建议性提醒。它从不延迟、阻止或改写调用；模型自行决定是换种方式重试还是结束。
+
+插件为 `@deepseek-ai/dsh-repeat-tool-guard`，位于 `packages/guard/repeat-tool-guard/`，开辟 `guard/` 分组用于循环卫生插件（单包（package）分组有先例：[todo-write Agent Note](2026-06-29-todo-write-tool.md)发布了 `todo/tool-todo`）。它注册两个监听器，将状态保存在以存活 `Agent` 对象为键的 `WeakMap` 中——工具注册表是上下文级别的单例，其 waterfall（瀑布式事件）交错所有 agent（智能体）的调用（subagent 运行在同一个上下文上），因此按 agent 分键是正确性要求，而非锦上添花；弱对象键还使得纯清理用途的 disposal 监听器不再必要。
+
+- **`tools/post-execute`（waterfall）**——唯一的检测点。监听器同时接收 `(exec, result)`，因此计数和提醒投递无需跨事件的 pending map（pi 扩展需要它，仅因为其 `tool_call`/`tool_result` 钩子是分开的事件）。它始终通过 `next()` 委托，当命中阈值时，将提醒前置到下游决策的 `additionalContexts`——这正是[钩子桥接](2026-06-30-hook-bridges.md)已采用的「观察并丰富」姿态，遵守 waterfall 契约。计数放在此处而非 `tools/pre-execute`，因为 post-execute 也会为被拒绝的调用触发（`ToolRegistry.execute` 将 deny 路由到同一条流水线），而模型反复敲击一个被拒绝的调用恰恰是值得打破的循环。
+- **`agent/prompt-submit`（waterfall）**——纯重置钩子：通过 `next()` 委托，清除提交 agent 的链。用户介入改变了上下文；跨越介入的重复不是循环。
+
+### 检测语义
+
+链的键是 `(tool name, canonical arguments)`；与前一个被追踪调用相同的调用递增该 agent 的连续计数器，不同的被追踪调用将其重置为 1。规范化方式为深度键排序加 `JSON.stringify`：`ToolExecution.arguments` 按构造就是循环中 `JSON.parse` 的输出（或格式错误的参数 JSON 的原始字符串回退，其本身也是可比较的值），因此 pi 原版对 bigint/循环引用/`undefined` 的处理在此没有输入，被有意去除。
+
+两条刻意的规则，均记录在[包 README](../../../../packages/guard/repeat-tool-guard/README.md) 中，因为它们是读者否则只能猜测的行为：
+
+- **未追踪的调用对链透明。** 被 `include`/`exclude` 排除的调用既不递增也不重置计数器，因此 `grep X → todo_write → grep X` 在 `todo_write` 被排除时仍计为两次连续的 `grep X`。这正是排除功能有用的原因——穿插在循环中的簿记工具不得为循环洗白——也是 pi 扩展的（未文档化的）语义，有意保留并明确写下。
+- **没有 agent 的调用被忽略。** 直接调用 `ctx.tools.execute()` 的调用方（测试、非循环消费方）没有可提醒的模型，也没有可作键的存活 agent 对象。
+
+### 提醒投递
+
+提醒作为独立条目搭载在 `additionalContexts` 上（source 为 `{kind: 'plugin', plugin: 'repeat-tool-guard'}`——依照 `HookContext`，该标签承载语义），绝不替换 `content`：`tool/result` 事件仍是工具自身的审计输出，循环则在步骤结果之后把缓冲的上下文追加为 `context/message`，会话将其渲染为带标签的合成 user 信封，并由派生历史回放。阈值逐级升级：第一个配置阈值获得简短的「你正在重复自己，请分析先前结果」提示；后续各阈值获得详细形式，包含工具、重复计数和规范参数（在头部截断到 `argumentsPreviewChars`，默认 500——循环中的 `write` 级 payload 不得无界地进入下一次请求；链键始终比较完整规范字符串），并说明这些调用没有取得进展。pi 原版把温和文本硬编码为字面计数 3；本守卫以 `thresholds[0]` 为键，修复了移植中的这一 bug。下游钩子桥贡献仍是独立数组条目，因此两个插件都保留各自的 source、信封与元数据。
+
+### 配置
+
+```yaml
+- id: repeat-tool-guard
+ name: '@deepseek-ai/dsh-repeat-tool-guard'
+ config:
+ thresholds: [3, 5, 8] # default; consecutive counts that trigger a reminder
+ include: [] # tool-name patterns to track; empty ⇒ all tools
+ exclude: [todo_write] # tool-name patterns transparent to the chain
+ argumentsPreviewChars: 500 # default; cap on arguments quoted in the detailed reminder
+```
+
+`thresholds` 在加载时校验，遇到空列表、非整数、小于 2 的值或重复项时抛出异常——配置错误快速失败，取代 pi 原版的静默回退到默认值。`include`/`exclude` 条目支持 `*` 通配符。模式是对调用时实际存在的工具的谓词，而非对注册表条目的引用，因此匹配不到当前已注册工具的条目不是错误——与 `toolOrder` 的引用检查不同，`exclude: [mcp_*]` 在未加载 MCP 工具的部署中也必须保持有效。
+
+## 测试
+
+- **单元测试：** 使用脚本化适配器的真实循环，覆盖计数与重置规则、未追踪透明性、dispose（资源释放）清理、按 agent 隔离、规范化参数键序、升级、被拒绝的调用、无 agent 执行、通配符转义、无效配置，以及下游阻止或 replacement 决策，达到逐文件 100% 覆盖率。
+- **快照测试：** keyless 的 `repeat-tool-guard` 场景发起五次相同的 `todo_write` 调用，在 ACP 输出和会话日志中固定第三次调用的温和提醒与第五次调用的详细提醒。该插件在实时示例中加载，但在其他场景中保持静默。
+- **E2e 测试：** 无。该插件是确定性的且与提供方无关，其 seam 契约由各自的所有者覆盖。
+
+## 曾考虑的替代方案
+
+- **将提醒追加到工具结果中**（以替换 `content` 的方式 `accept`——pi 扩展的机制，它修补结果内容是因为那是其 API 提供的唯一通道）：否决。这会让已记录的 `tool/result` 对工具实际返回的内容撒谎，而 `additionalContexts` 是 post-execute 评注的独立认可通道，循环级缓冲保持了调用/结果的邻接关系。
+- **在 `tools/pre-execute` 中计数并使用 pending-reminder map**（pi 的两阶段形态）：否决。post-execute 单独就能同时看到 `(exec, result)` 且也为被拒绝的调用触发，因此一个监听器、无跨事件状态即可以更少的机制覆盖严格更多的尝试。
+- **在最高阈值升级为 `block`**：在初始范围内否决。阻止调用会惩罚合法的相同重复（轮询长时间运行的终端、重新检查 agent 预期会变化的文件），而建议性提醒让模型保持控制权。待有证据后重新审视；决策形状（`PostToolDecision`）已支持此选项。
+- **通过 CC/Codex 桥接的逐部署外部钩子**（一个 `PostToolUse` 脚本）：否决作为最终答案。它对单个部署有效，但一个已发布、有单元测试、可通过 `cordis.yml` 配置的插件才是 harness 原生的形式，且没有逐调用的子进程开销。
+- **在 `agent-loop` 中设置循环级步骤或重复预算**：否决。「用插件，不改循环」；硬性步骤预算是一种更粗粒度的正交控制，需要自己的提案。
+- **模糊/近似相同检测**（路径归一化、相似但不完全相同的参数）：否决。规范化后的精确匹配成本低、确定性强、且可向模型解释；相似度阈值引入误报风险，需要证据才能换取复杂度。
+- **将包放在 `core/`**：否决。core 是产品主干；行为守卫是可选的叶子插件，`todo/` 的先例是每个插件族一个小型专属分组。
+
+## 后果
+
+- 提醒在设计上是建议性的：有意重复相同调用的幂等轮询模式仍会在超过阈值后收到提示，减压阀是配置（`thresholds`、`exclude`）加上明确允许「在已收集足够证据时结束」的提醒文本。每次触发在下一次请求中增加提醒 token 的开销；阈值限制了触发频率。
+- 链状态仅存于内存：从持久化恢复的会话以全新的链开始，因此跨越恢复的循环比实时循环更晚收到提醒——可以接受，守卫是启发式提示而非已记录的不变式，持久化计数器状态带来的收益不值得其复杂度。
+- 当多个 post-execute 生产者在同一次调用上附加上下文时，每项贡献保持为独立的 `HookContext`；顺序遵循 waterfall 嵌套关系，每个条目保留自己的溯源信息。
+- 实现快照层时暴露了 suite kit 的一项隐藏假设：fixture guard 把「撰写的模型场景」等同于「由 override 驱动」。`Scenario` 表现在携带显式的 `overridden` 标志，并且 sidecar 是否存在会以双向方式与其核对（未注册的游离 sidecar 会静默替换派生脚本）——suite kit 比本插件出现前更严格。
+
+## 延后事项
+
+- 压缩（compaction）不重置链：压缩后的历史改变了模型所见的内容，但重复风险通常在压缩后仍然存在。
+- 在高阈值升级为 `block` 未实现；`PostToolDecision` 已支持此选项，待证据到来时启用。
+- subagent 的链按 agent 隔离；在出现具体用例之前不提供共享机制。

## Problem
Everything in this harness is a cordis plugin, but the agent running inside that plugin runtime cannot see or touch it: it cannot enumerate the services and events around it, cannot extend itself with a new tool mid-session, and cannot compose capabilities it invents. Handing the model that power is worth exploring — a self-referential agent that inspects and modifies its own runtime — but it raises three correctness problems at once, and the design is about answering them rather than the raw "let the model run code" mechanic.

+# Agent Note: 自引用 cordis 工具集
+
+Status: implemented
+
+[English](2026-07-08-self-referential-cordis-toolset.md) | 中文
+
+## 问题
+
+本 harness 中的一切都是 cordis 插件，但运行在该插件运行时内部的 agent（智能体）既看不到也碰不到它：它无法枚举周围的服务和事件，无法在会话中途为自己添加新工具，也无法组合自己发明的能力。赋予模型这种能力值得探索——一个能审视并修改自身运行时的自引用 agent——但这同时引发三个正确性问题，本设计的核心正是回答这些问题，而非单纯的「让模型执行代码」机制。
+
+第一，模型编写的注册必须在注册发生时就完成校验：格式错误的工具 schema 必须在注册时失败，而不是等到后续请求尝试将其组装进提示词时才报错。第二，模型编写的代码需要调用它从未见过源码的服务 API——靠猜测方法签名、更糟糕的是猜测返回值结构，会消耗大量盲目试探的步骤。第三，模型挂载的一切都必须完全可释放：模型可以按需释放，普通的插件生命周期在宿主插件重载时也会释放，否则长会话会积累遗留的监听器和工具。
+
+## 决策
+
+该工具集以 [`@deepseek-ai/dsh-tool-cordis`](../../../../packages/cordis/tool-cordis/README.md) 发布——一个新的顶层 `packages/cordis/` 分组——并由 [`examples/cordis-agent`](../../../../examples/cordis-agent/README.md) 演示。它为模型提供三个工具，操作模型自身运行其中的活跃 cordis 运行时：审视它、将模型编写的插件挂载进去、再将其释放。
+
+vm 隔离了意外的全局污染，上下文门面隐藏了框架内部细节。但二者都不限制已暴露服务的权限：一个挂载可以调用 `ctx.bash` 以宿主执行器的权限运行命令，也能访问真实的文件系统和网络服务。这是一个需要显式启用的开发工具，信任等级与 bash 相当，不是安全边界，也不是产品默认配置。
+
+### 三个工具
+
+| 工具 | 契约 |
+|---|---|
+| `cordis_inspect` | 对活跃运行时的只读报告，每个 `what` 值对应一个 Markdown 段落（省略 `what` 则输出全部段落）。精确的 `name` 搭配 `what: "api"` 或 `what: "events"` 可收窄到一个带源码文档的目标。从不产生变更。 |
+| `cordis_mount` | 在 `node:vm` 沙箱中执行 `code`（一个异步 JavaScript 函数的函数体）；代码必须 `return` 一个 cordis 插件，该插件作为 `cordis-dynamic` 分组 fiber 的子节点挂载，并以一个新 id（`dyn-1`、`dyn-2`……）跟踪。 |
+| `cordis_unmount` | 按 id 释放一个动态挂载，并等到释放达到完全停稳后才返回——该插件所做的每一项注册都被撤销，而不仅仅是请求停止。 |
+
+`cordis_inspect` 的段落：`services`（每个已提供的 ctx 服务及其所属 fiber，非活跃的所有者会被标记）、`plugins`（来自 `ctx.registry` 的所有已加载插件的扁平列表及其生命周期状态——展示加载了哪些能力，刻意不展示树形结构）、`tools`（模型可调用的工具）、`dynamic`（挂载表：id、名称、状态、提供的服务、等待的服务）、`api`（来自生成目录的活跃服务签名及其引用的类型形状）和 `events`（harness 事件及其分发模式和签名）。宽泛的 `api` 和 `events` 报告省略完整 JSDoc 以保持紧凑；精确 `name` 会返回一个服务或事件，以及其原始方法/声明 JSDoc。其他段落不能搭配 name，未知目标会失败，而 API 目标必须处于活跃状态。面向模型的工具描述携带了模型在调用时所需的操作规则；[生成的工具目录](../../../../docs/tool-catalog.md)是其完整呈现。
+
+### 沙箱语义
+
+挂载代码以异步函数体的形式在一个新的 vm realm 中运行。其文档化的接口面将文件、网络、进程和定时器访问引导至 Cordis 服务，使挂载保持可审视和可释放。宿主 realm 的辅助手段仍然使 Node 逃逸成为可能，这与信任姿态一致。`vmTimeoutMs` 仅约束同步执行部分。
+
+沙箱全局变量刻意精简：一个带标签的直写 `console`（在宿主 stdout/stderr 上输出 `[cordis:<id>] …`，这样在挂载调用之后很久才触发的监听器输出仍能落到用户可见的地方）、`harness.defineTool` / `harness.registerTool` 注册对、新 vm 上下文缺少的编码原语（`btoa`/`atob` 作为基于 `Buffer` 的宿主闭包——这是一个经过审批的例外，`Buffer` 本身从不暴露——加上 `TextEncoder`/`TextDecoder`），以及对被扣留的 Node API 的可调用陷阱（`require`、`setTimeout`/`setInterval`/`setImmediate`/`clearTimeout`/`clearInterval`、`fetch`），这些陷阱会抛出一条重定向消息指明 cordis 替代方案。只有函数形态的全局变量才设陷阱；`process` 和 `Buffer` 保持 `undefined`，这样 `typeof` 特性探测保持惰性而不会引爆一个抛异常的访问器。
+
+挂载代码通过三道控制跨越 vm 边界。双 realm `instanceof` 同时识别宿主和 vm 对象。`harness.defineTool` 在宿主 realm 中重建输出 schema／投影器，将工具体返回值快照为宿主自有的 JSON，并让注册表在观测前强制执行[规范工具输出契约](../architecture/2026-07-20-canonical-tool-output-contract.md)。挂载的插件接收的是一个白名单上下文门面，而非原始或透传的 `Context`；框架管道和以 context 为值的返回会被拒绝。服务读取需要声明 `inject`，保留 Cordis 的激活与卸载语义。`ctx.tools.get` 仅暴露 schema 视图，因此挂载代码无法绕过 `ToolRegistry.execute` 直接调用定义。
+
+边界将无歧义的 JSON-Schema 形式规范化为 `ParameterSchemaSpec`，同时保留 `integer`、原始对象开放性和 required 数组。直接使用 DSL 的对象节点必须声明 `additionalProperties`；无效词汇会报错并给出可接受的替代方案。解析错误、TypeScript 错误、缺少 return、Node API 误用和重复工具名等错误信息包含相关源码行或纠正性契约，不叙述实现内部细节。
+
+### 动态分组与挂载生命周期
+
+所有动态挂载都是工具插件下方 `cordis-dynamic` 分组的子节点，因此普通的 fiber 释放即可处理重载和卸载。挂载会等待 settlement；启动失败时在返回错误前释放 fiber。已 settle 但处于 pending 状态的挂载仍然可见，并列出其缺失的注入。`cordis_unmount` 等待挂载 fiber 的释放完成。
+
+### 通过 provide/inject 实现跨挂载组合
+
+挂载之间通过普通的 cordis 服务语义相互关联，以各自的 id 作为生命周期句柄：挂载 A 调用 `ctx.provide('foo', value)`，挂载 B 声明 `inject: ['foo']` 并在 `foo` 存在的瞬间激活；如果 B 先挂载，它保持 pending 状态并列出缺失的服务；卸载 A 使 B 回到 pending（其注册被撤销），之后重新 provide 会通过一个新的沙箱门面重新运行 B 的 `apply`；重复 provide 会明确报错并指出拥有该服务的 fiber。一个 realm 注意事项：由挂载 provide 的服务值是 vm realm 对象——从任何地方调用其方法都能工作，但消费方不得假设它具有宿主原型。
+
+### 生成的 API 目录
+
+`cordis_inspect` 从生成的目录提供 API 和事件数据，而非维护一份重复的表格。生成器复用 Cordis 目录的 AST 扫描，输出服务摘要、签名、原始服务方法与事件 JSDoc、事件模式、引用的类型声明以及继承的上下文接口面。有歧义的类型名被省略，过大的声明被标记为截断。
+
+新鲜度像所有生成产物一样受门禁约束：`pnpm run verify-cordis-api`（在 `doc-sync` 中）在内存中重新生成并在有任何 diff 时失败，因此 JSDoc 或公开签名变更如果不重新生成模型读取的目录就无法合入。运行时 inspect 工具将目录与活跃运行时取交集而非直接转储：宽泛报告把有目录条目的活跃服务渲染为摘要 + 签名，把没有目录条目的活跃服务（挂载提供的）渲染为名称 + 所属 fiber，简要列出有目录条目但无活跃提供方的服务，再附上引用的类型形状。精确名称报告渲染一个活跃服务或事件，并把原始 JSDoc 紧靠在每个签名之前；让该细节按需出现，避免探索性列表承担其 token 成本。
+
+### 配置、渲染与可观测性
+
+该插件暴露一个配置字段，由 schemastery 校验并记录在[配置目录](../../../../docs/config-catalog.md)中：`vmTimeoutMs`（默认 5000），挂载代码同步执行部分的毫秒上限。工具名、`cordis-dynamic` 分组名和 `dyn-` id 前缀是结构性词汇，保持固定。三个工具均按[工具实操手册](../../../../docs/cookbook/adding-a-tool.md)渲染为 `generic` 卡片（`cordis_inspect` 为 `read`，`cordis_mount` 为 `execute` 并将代码作为 `rawInput` 携带，`cordis_unmount` 为 `delete`），不覆盖 `presentResult`。
+
+「模型可见 ⟺ 已记录」成立，且无需新的会话事件类型：挂载或卸载仅通过其自身的 `tool/call` / `tool/result` 对可见（循环会记录它们），而挂载引起的工具集变化由循环在 schema 在步骤间发生变化时发出的完整变更 request header 记录。刻意不设 `cordis/mount` 溯源事件——它只会重复工具调用对已记录的内容。动态挂载是进程生命周期的，不是会话状态：恢复一个持久化的会话会重建对话，但不会重新挂载插件。
+
+## 曾考虑的替代方案
+
+**用结构化的逐能力注册工具替代 `cordis_mount`。** 最具吸引力的替代方案是一个带有显式 `name` / `description` / `parameters` / `code` 字段的 `cordis_register_tool`（以及兄弟工具 `cordis_register_listener`、`cordis_register_service`……），而非单一的「挂载一个插件」原语。否决原因：它唯一的真正优势——对最常见的单一场景免去插件样板代码——不足以抵偿其代价，而单一的 mount 原语能一次性覆盖所有能力。
+
+| 维度 | 结构化逐能力工具 | 单一 `cordis_mount` |
+|---|---|---|
+| Schema 正确性 | `parameters` 仍然是模型编写的 JSON，需要统一 schema 校验，只是提前了一步 | 同样的校验在沙箱边界运行，同样的指导性错误信息 |
+| 代码字段 | `execute` 函数体仍然是 vm 中模型编写的 JS；realm 和服务调用的正确性问题不变 | 一个沙箱、一条规范化路径、一处受保护的注册 |
+| 能力覆盖面 | 仅限工具；监听器、服务、`inject` 关系各需另一个结构化工具——接口面无限增长 | 一套词汇（cordis 插件）覆盖当前和未来的所有效果 |
+| 跨挂载组合 | 在工具注册载荷中无法表达 | 原生 `provide`/`inject`，普通的 cordis 语义 |
+| 可审视性 | 注册的东西无法在插件列表中显示为插件 | 模型挂载的正是 `cordis_inspect` 渲染的 |
+| 模型易用性 | 对最常见的单一场景有优势（无插件样板） | 通过 mount 描述中的规范示例加边界错误信息教会正确调用来缓解 |
+
+因此正确性投入放在能一次性为所有能力带来回报的地方：通过 `cordis_inspect` 呈现的生成 API 目录，以及沙箱边界校验（其错误信息教会正确的调用方式）。结构化注册工具日后仍可作为语法糖添加，由它合成 mount 代码；本设计不排斥这一可能。
+
+**在工具中手工维护服务/事件参考。** inspect 工具的第一版携带了一份手写的服务方法签名表。它被生成的 `api-catalog.ts` 取代，因为手写表在签名变化的瞬间就会与 JSDoc 脱节且没有门禁约束这种漂移，而生成产物的新鲜度由文档使用的同一套 AST 检查。
+
+**新增 `cordis/mount` 会话事件。** 一个持久的溯源事件记录每次挂载（源码、名称）有明确先例（`hook/invoked`、`compact/start`）。v1 中予以否决：挂载和卸载已经作为 `tool/call` / `tool/result` 对可见，工具集变化已经作为完整的变更 request header 被记录，因此专用事件只会重复记录。如果审计用例需要将挂载溯源从工具调用中分离出来，日后仍可添加。
+
+**加固的/能力受限的沙箱。** 对 Node 内置模块设陷阱并向挂载代码提供白名单门面而非原始上下文，可能暗示意图是为安全而沙箱化。这里明确不是：陷阱和门面收窄的是挂载代码所见的*接口面*——将其引导至 cordis 服务、远离易泄漏的 Node 内置模块和框架内部——目的是正确性和封堵未受保护的上下文逃逸，但门面暴露的能力（`ctx.bash`、`ctx.fs`、`ctx.web`）触及真实运行时，因此它不是安全边界。真正的安全边界（独立进程、权限提示）超出了一个开发/显式启用工具集的范围，且会与其核心目的——将活跃运行时交给模型——相冲突。
+
+## 后果
+
+该工具集是刻意的显式启用设计，具有完全特权的 `ctx`，因此部署方采用它的意识程度应与 bash 工具相当。以下几个事实由工具描述直接告知模型：一个 waterfall（瀑布式事件）监听器（如 `tools/pre-execute`）如果不调用 `next()` 就返回，会否决整条链，因此一个挂载的监听器可以瘫痪 agent 自身的工具分发（[waterfall 语义](../../../../docs/cordis-primer.md#cordis-waterfall-semantics)）；挂载代码在当前轮次的工具调用内运行，因此 await 任何只在该轮次结束后才 resolve 的东西会导致死锁；`vmTimeoutMs` 仅约束同步执行；挂载不会在会话恢复后存活。

## Problem
Session history exists in two places: current `SessionStore` objects and an optional persistence backend. Consumers that need exact inspection would otherwise duplicate live-versus-persisted precedence, persistence lifecycle handling, raw-event surface classification, relationship tracing, and defensive cloning. Durable state can lag the live log between checkpoints, so persistence alone is not a truthful current source.

+# Agent Note: 精确会话查询服务
+
+Status: implemented
+
+[English](2026-07-10-session-query-service.md) | 中文
+
+## 问题
+
+会话历史存在于两处：当前的 `SessionStore` 对象与可选的持久化后端。需要精确检查的消费方若无统一服务，就不得不各自重复实现活跃/持久化优先级判定、持久化生命周期处理、原始事件的 surface 分类、关系追踪以及防御性克隆。在检查点之间，持久化状态可能落后于活跃日志，因此仅靠持久化并非当前状态的可靠来源。
+
+全文搜索与此相关，但规模大得多。将提供方协调、同步、失效、排序和游标状态放入精确读取服务，会在具体数据库拥有方旁边再创建一个状态机。
+
+## 决策
+
+`@deepseek-ai/dsh-session-query` 拥有面向单一逻辑语料库的唯一抽象 `ctx.sessionQuery` 服务。它具体实现 `listSessions()`、提供方无关的 `filterSessions(filters)`、`listEvents(sessionId)`、`filterEvents(sessionId, filters)`、有界的 `readEvent(request)`、`traceSession(sessionId)` 和 `traceEvent(request)`，而具体后端实现其两个全文搜索方法。[统一服务决策](../architecture/2026-07-23-unified-session-query-service.md)拥有这一拓扑，[SQLite 搜索决策](2026-07-10-sqlite-session-query-provider.md)拥有搜索行为，[追踪决策](2026-07-13-session-query-tracing.md)拥有血缘与事件关系语义。
+
+该服务动态观察可选的 `ctx.sessionPersistence` 绑定，但不保留持久化缓存或失效监听器。每次跨语料库列表操作向活跃后端请求权威元数据，然后叠加一份新鲜的活跃 store 列表。id 匹配的条目合并为一条 `SessionRecord`：活跃 header 优先，`live`/`persisted` 各自独立报告来源可用性。不可变 header 不一致时产生 `SESSION_QUERY_SOURCE_CONFLICT`。
+
+精确目标读取首先检查活跃 store，快照活跃 header 与事件日志。此路径从不查询持久化，因此持久化后端故障不会导致已知的活跃历史不可读。若活跃 store 中无目标，服务列出当前持久化元数据、证明该 id 存在、加载它，并在列表/加载 header 不一致时拒绝。所有返回的 header 与事件都经过一次 structured-clone 边界。
+
+## Surface 语义
+
+`dsh-session` 导出 `foldSurface(events)`，`SurfaceManager` 使用相同的转换函数维护其增量缓存。fold 返回分离的当前事件 seq 以及每次替换实际移除的 seq。`listEvents()` 和 `traceEvent()` 利用该结果为每个原始事件分类，使检查结果不会在位置替换语义上与 model-history 推导产生分歧。
+
+`readEvent()` 返回完整的目标加上按连续 seq 排列的原始相邻事件。`before` 和 `after` 默认为零，各自受 `readWindowMax`（默认 50）约束。结果携带克隆的 `SessionHeader` 而非来源可用性记录，因为判断活跃目标的 persisted 标志会违反「活跃精确读取不依赖持久化健康状态」这一保证。
+
+## 安全边界
+
+该服务是上下文级别的受信任基础设施，而非授权层。未来面向模型的历史工具或人类 UI 将施加显式的调用方/会话范围。该服务不添加面向模型的工具，也不改变 transcript（文本记录）或快照的 surface。
+
+## 曾考虑的替代方案
+
+- **将逻辑语料库解析直接放在每个消费方中**：否决。来源优先级、冲突处理、可选服务生命周期、克隆与 surface 分类是共享的正确性规则。
+- **仅查询持久化**：否决。检查点可能落后于当前活跃日志。
+- **缓存持久化元数据并监听写入/删除**：否决。精确读取可以直接询问权威来源，而缓存失效在规模尚未要求时就引入了生命周期与并发状态。
+- **将提供方注册放入精确读取服务**：否决。SQLite 包拥有一套对账/事务生命周期；若没有第二个提供方证明其必要性，注册表只会拆分该状态。
+
+## 后果
+
+继承的精确读取实现只有一个来源解析状态变量：当前挂载的持久化服务。它没有提供方队列、指纹、提取器注册表、观察代次或派生索引更新；具体后端单独拥有其全文搜索状态。精确读取、语义扫描和事件追踪在纯活跃部署中仍然可用，在持久化存在时具有确定性。
+
+跨语料库列表、血缘追踪和持久化事件操作在每次调用时执行后端 I/O。这是有意为之：正确性来自当前权威状态，而面向规模的全文搜索方法使用具体后端的 SQLite 派生索引。

## Problem
The exact-read `ctx.sessionQuery` service deliberately has no derived index. Large persisted histories need full-text search without scanning every event on every query, while current live sessions need an overlay newer than the last durability checkpoint. Search also needs concrete ranking, snippets, filters, pagination, cancellation, and rebuild behavior.

Structural boundaries, stream chunks, request headers, successful completion markers, and unknown declaration-merged event/content variants produce no document. Surface classification reuses `foldSurface()` so search agrees with model-history derivation.

+One serialized operation reads the provider-neutral `SessionPersistence` snapshot listing, compares each source-qualified opaque revision with the revision stored beside the indexed session, loads only new or changed logs, reconciles rows in one transaction, and executes the query. It passes the caller's exact abort signal into snapshot listing and non-mutating inspection, directly awaits every started backend operation, and checks cancellation after each await and before starting more work. Cancellation therefore rejects only after active backend work is quiescent, starts no subsequent observation or reconciliation step, and keeps a following search serialized behind cleanup even if a backend ignores the signal.

Persisted documents survive restarts. Live sessions use connection-local TEMP tables, shadow the persisted base for the same id, and reveal that base on detach. Closing the database drops live rows. Unmounting persistence hides durable rows without treating absence as authoritative deletion; remounting observes and reconciles the backend again. Conflicting immutable live and durable headers fail rather than combining sources.

One service in one process exclusively owns a derived-index path; cross-process writers are unsupported because generations and live TEMP shadow state are connection-owned.

+## 问题
+
+精确读取的 `ctx.sessionQuery` 服务有意不维护派生索引。大规模持久化的历史记录需要全文搜索，而不是每次查询都扫描全部事件；当前的活跃会话则需要一个比上一次持久性检查点更新的覆盖层。搜索还需要具体的排序、摘要片段、过滤器、分页、取消以及重建行为。
+
+如果把这些关注点拆分到提供方协调器和数据库实现之间，就会产生两个耦合的对齐状态机。第一个实现既要暴露精简的提供方无关调用契约，也要在同一个生命周期内管理源观察、提取、SQLite 事务、代际与查询执行。

+`@deepseek-ai/dsh-session-query` 声明一个抽象的 `ctx.sessionQuery` 服务，其精确读取、过滤与追踪均有具体实现，仅有两项全文方法为抽象方法。`searchSessions(request, exec?)` 返回按游标分页的 `SessionSearchHit`，并按每个会话中匹配度最强的事件分组；`searchEvents(request, exec?)` 返回一个逻辑会话内的 `SessionEventSearchHit`。两种请求都必须提供 `query`，可以接受 `limit` 和由服务拥有的品牌化 `SessionSearchCursor`，并支持可选的中止信号。会话搜索接受 `sessionFilters` 与事件元数据过滤器，事件搜索接受事件元数据过滤器。结果会公开有界的纯文本摘要片段，但不公开提供方标识符或数值相关性分数。单一键拓扑由[统一服务决策](../architecture/2026-07-23-unified-session-query-service.md)定义。
+
+`@deepseek-ai/dsh-session-query-sqlite` 扩展接口服务，并且是 `ctx.sessionQuery` 唯一的具体所有者。它依赖实时的 `ctx.sessions`，动态观察可选的 `ctx.sessionPersistence`，并拥有一个专用的派生 SQLite 数据库。系统没有搜索提供方注册表、协调器、持久化事件或 agent loop（智能体循环）集成。
+
+接口包还拥有共享的第一方语义提取与提供方无关的过滤。`SessionResultFilter` 涵盖 id、可空的 cwd、创建时间范围、可空的父会话与可用性；`ctx.sessionQuery.filterSessions()` 无需 FTS 提供方即可应用这些过滤器。`SessionEventResultFilter` 涵盖 seq/时间范围、事件类型、surface 与字面语义文本。过滤器数组内各项按逻辑与（AND）组合，列表值按逻辑或（OR）组合。文本子句会将调用方输入转义为不区分大小写的 Unicode 正则表达式，其中每段连续空白都匹配一个或多个空白字符；该子句通过 `ctx.sessionQuery.filterEvents()` 提供，不会委托给 FTS 提供方。
+
+## 搜索语义
+
+每个语义事件对应一份 FTS 文档，其中携带会话元数据、事件元数据、surface 分类与提取文本。除非 surface 过滤器缩小范围，否则所有 `current`、`shadowed` 与 `log-only` 文档都会参与搜索。元数据过滤器在排序前编译为参数化 SQL。会话结果按会话划分匹配文档，并保留匹配度最强的文档。
+
+排序在持久化 FTS 表与 TEMP FTS 表之间具有确定性和可比性：先按实际 FTS5 高亮匹配区段数量降序，再按已索引文档的码点长度升序、事件时间降序、跨会话范围内的会话 id 升序，最后按 seq 降序排列。摘要片段使用这些实际高亮位置，移除保留标记、规范化空白，并按 Unicode 码点限制长度。不透明游标会绑定到服务实例、范围、规范化后的标准请求、偏移量与相关代际。语料库发生任何变更都会使跨会话游标失效；会话内游标仅在其目标源或代际发生变化时失效，因此不相关的会话不会使其失效。重新打开服务会创建新的服务实例，并使旧游标失效。
+
+查询会先去除首尾空白并规范化内部空白，再作为一个字面 FTS5 短语整体加引号。嵌入的引号在绑定前写成两个，因此 `OR`、`NEAR`、引号、括号与 `*` 等 MATCH 运算符会作为数据，而不是可执行的查询语法。系统会在 SQLite 执行前拒绝 NUL。文档中的保留高亮非字符与 NUL 会在索引前规范化，因此插入的呈现标记不会与源文本冲突。短语匹配遵循分词器 token，而不是任意子串。
+
+## 分词器选择
+
+持久化 FTS5 表与实时 FTS5 表都使用 `unicode61`。实现实验表明，该分词器支持由两个字符组成的 token `AI`，生成的索引体积约为 trigram 方案的 1/2.1。系统接受的限制是 token/短语召回：`AI` 不会匹配较长的 token `BRAID`，任意子串搜索改用提供方无关的文本扫描。
+
+## 提取与对齐
+
+共享提取器会提取消息文本、推理（reasoning）、嵌套的工具调用/结果内容、工具名称与参数、被阻止提示词的原因、待办事项状态与内容，以及错误或结束状态详情。结构性边界、流式分片、请求头、成功完成标记，以及通过声明合并扩展的未知事件/内容变体都不会产生文档。surface 分类复用 `foldSurface()`，使搜索与模型历史派生保持一致。
+
+一个串行化操作会读取提供方无关的 `SessionPersistence` 快照清单，将每个包含源身份的不透明修订号与同已索引会话一并存储的修订号比较，只加载新增或变更的日志，在一个事务中对齐各行，然后执行查询。它绝不会调用后端会修改状态的 `load()` 来处理当前由 `ctx.sessions` 拥有的 id；TEMP 覆盖层会记录持久化可用性，实时所有者分离后，持久化基础层随之刷新。修订号同时标识其底层持久化存储与后端本地日志修订版本，因此针对同一存储重新打开服务可以复用已索引行，而切换到独立存储时不会因会话 id 与本地计数器相同而发生冲突。如果加载期间清单发生变化，系统会重复观察；因此，会修改状态的加载修复所产生的新修订号会在提交前纳入结果。重复查询与针对未变更存储的重新打开都不会加载完整的持久化日志。新增、变更与删除的会话会在下一次稳定搜索中更新。源或提取失败不能将某一行标记为当前状态，事务失败则会回滚，使后续搜索能够重试。
+
+持久化文档在重启后仍然存在。实时会话使用连接本地的 TEMP 表，遮蔽相同 id 的持久化基础行，并在实时所有者分离时重新显露该基础行。关闭数据库会删除实时行。卸载持久化服务会隐藏持久化行，但不会把缺失视为权威删除；重新挂载后，系统会再次观察并对齐后端。实时会话头与持久化会话头的不可变字段发生冲突时，系统会失败，而不会合并两个来源。
+
+派生 schema 拥有独立的 application id 与单调递增的 schema 版本。持久化与 TEMP 会话元数据均遵循 `SessionHeader.createdAt` 的整数契约，将其存入严格的 `INTEGER` 列。系统识别到不兼容版本时，只会重置该派生数据库。如果数据库具有不属于本应用的 application id 或无法识别的用户表，系统会在修改日志模式前拒绝该数据库，防止意外配置的规范会话数据库遭到修改。在 POSIX 文件系统上，缺失的目录与数据库文件会以仅所有者可访问的权限创建，使新的 SQLite 伴随文件沿用该模式；现有权限模式保持不变。一个进程中的一个服务独占一条派生索引路径；代际与实时 TEMP 遮蔽状态都归连接所有，因此不支持跨进程写入方。
+
+取消会拒绝排队中的操作，并终止调用方对异步源观察的等待；已经中止的观察结果不会提交。Node 的同步 `DatabaseSync` MATCH 调用一旦开始在 JavaScript 线程上执行就无法中断，因此服务会在串行化边界检查信号，但不承诺在语句执行期间抢占。
+
+## 曾考虑的替代方案
+
+- **将 FTS 表添加到规范持久化数据库**：不予采纳，因为可重建索引不应与权威日志共享 schema、重置或故障边界。
+- **添加第一阶段的提供方注册表与协调器**：不予采纳，因为单一实现无法证明注册语义，并且会将一个对齐生命周期拆给两个所有者。
+- **立即持久化实时覆盖层**：不予采纳，因为在现有检查点提交前，实时事件并非规范数据。
+- **使用 FTS5 trigram 分词器**：不予采纳，因为它会遗漏短于三个字符的有用查询，并且测得的索引体积约为 `unicode61` 的 2.1 倍；扫描路径仍可提供字面子串过滤。
+- **在每个表中独立使用 FTS5 BM25**：不予采纳，因为填充内容不同的持久化语料库与 TEMP 语料库所产生的分数不可比较；实际匹配区段与文档长度采用同一套尺度。
+
+## 后果
+
+搜索只公开精简的提供方无关 API，而唯一后端负责派生索引的全部状态转换。独立数据库增加了配置与查询前的轻量快照读取，但索引损坏、重置与分词器变更都不会危及规范日志。持久化修订号使未变更会话无需读取或重写完整日志；TEMP 实时覆盖层保留当前会话事实，同时不会让尚未经过检查点的事件具有持久性。
+
+选定的分词器以较小的索引体积支持短 token，但不承诺子串召回。字面短语使查询语法安全且可预测，代价是不支持布尔表达式或完整 MATCH 表达式。取消在操作排队或等待数据源期间有效，但同步 SQLite 执行仍是不可抢占区段。
+
+单元测试将以下行为固化为契约：提取、过滤器、两种搜索范围、所有默认 surface、先过滤元数据再排序、摘要片段、字面量转义、确定性平局处理、完整分页、按范围的游标失效、动态挂载/卸载持久化服务、重启对齐、实时遮蔽、显露与重新打开、schema 安全、回滚重试，以及排队中或进行中的数据源等待取消。一个无需密钥的真实 Loader 路径测试会将该包与真实的 SQLite 持久化后端组合使用。

## Problem
A reusable subagent provider answers how to run a child, but different delegation tools need different child behavior. One deployment may want a reviewer persona, a research-only tool set, or a hard recursion bound without creating a new provider for every combination.

+# Agent Note: 配置 subagent 的人设、工具可见性与深度
+
+Status: implemented
+
+[English](2026-07-12-subagent-persona-tool-filter-and-depth.md) | 中文
+
+## 问题
+
+一个可复用的 subagent 提供方解决的是「如何运行子 agent（智能体）」的问题，但不同的委派工具需要不同的子 agent 行为。某个部署可能需要评审者人设、仅限研究的工具集，或硬性递归上限，而不必为每种组合创建新的提供方。
+
+这些控制影响子 agent 的第一次模型请求，因此不能在子 agent 可见之后再安装。它们还需要提供方的诚实支持：ACP（Agent Client Protocol）后端不能默默接受一个仅限进程内的工具过滤器，而过滤器在所有插件运行于同一可信进程的情况下也不应被描述为安全边界。
+
+## 决策
+
+subagent 启动有三个独立的组合控制：`persona`、`toolFilter` 和 `maxDepth`。提供方声明对每个控制的支持情况，服务在启动运行之前拒绝不受支持的请求，进程内提供方在子 agent 尚未发布时安装所请求的组合。
+
+这些控制回答不同的问题：
+
+| 控制 | 问题 | 结果 |
+|---|---|---|
+| `persona` | 什么角色指令替换该子 agent 的部署人设？ | 一个子 agent 局部的提示词段落遮蔽 `deployment:persona` |
+| `toolFilter` | 部署全局工具中哪些进入该子 agent 的可见工具视图？ | 一个有作用域的限制在添加子 agent 局部工具之前过滤全局工具 |
+| `maxDepth` | 这棵委派树最深可以长到多少层？ | 子 agent 深度超过绝对上限时，启动请求被拒绝 |
+
+`dsh-tool-subagent` 将这些控制作为插件配置暴露，并复制到它创建的每个请求中。直接调用 `SubagentService` 的调用方可以按请求选择这些控制。提供方的能力描述符仍然是后端能否兑现各字段的真源。
+
+### 人设是有作用域的遮蔽
+
+人设控制改变一个子 agent 的行为，而不改变部署级的提示词组装。在未发布的设置阶段，进程内提供方在子 agent 作用域中注册一个名为 `deployment:persona` 的段落；普通的最具体者优先解析规则仅在该子 agent 的组装中替换全局段落。
+
+其值与部署人设具有相同的严格模板语义。省略时通过全局层继承部署段落；显式空字符串则以空段落遮蔽全局人设。父级和兄弟级的人设永远不会进入子 agent 的扁平作用域。
+
+这使用的是常规的系统提示词注册机制，而非第二条人设通道。因此第一次提示词看到的命名贡献与后续提示词和提示词检查工具看到的一致。
+
+### 工具过滤是一条作用于全局视图的活规则
+
+工具过滤同时控制能力可见性和可执行查找。进程内提供方在发布前于子 agent 作用域中安装 `ToolRegistry.restrict()`，注册表的单一解析器对协议格式（wire format）的工具 schema、查找、执行和 Code Mode SDK 生成施加相同的结果。独立注册的系统提示词段落不在 `ToolRegistry` 内，因此过滤一个工具不会移除该插件的独立指导文本。
+
+解析遵循以下规则：
+
+1. 每条限制对活跃的部署全局工具注册表先应用 `allow` 再应用 `deny`。
+2. 多条限制取交集，因此每条已安装的限制都必须放行一个全局工具。
+3. 子 agent 作用域的工具在全局过滤之后添加，可以遮蔽一个已放行的全局工具。
+4. 保留的 `run_code` 呈现和其他作用域局部的协议贡献不受全局过滤器影响。
+
+当过滤器既未提供 `allow` 也未提供 `deny`，或命名了当前全局可限制集合之外的内容（包括仅作用域局部或保留名称）时，配置会显式失败。`allow: []` 合法，且有意隐藏所有全局工具。这些检查能捕获拼写错误，并防止配置在无法影响所命名条目时看起来仍然有效。
+
+全局注册表保持活跃。仅 deny 的过滤器会放行后来注册的全局名称（除非显式 deny 该名称）；allow 列表会排除后来注册的全局名称（除非显式 allow 该名称）。移除一个全局工具会将其从所有已解析视图中移除。这些语义在保持热注册的同时，使 allow 与 deny 的区别显式化。
+
+### 深度是绝对的树上限
+
+深度限制独立于工具可见性来约束递归委派。顶层 agent 深度为零；进程内子 agent 的深度为其父级已验证深度加一。`maxDepth` 是一个绝对的非负安全整数，当推导出的子 agent 深度大于上限时，启动在子 agent 所有权开始之前即被拒绝。
+
+有效父级深度取持久 `SessionHeader.delegationDepth` 与运行时 `AgentOptions.subagentDepth` 中的较大值。进程内子 agent 把推导出的深度记录在会话 header 中，恢复时会重新载入该 header，因此重启无法降低递归计数。
+
+每个公开入口都自行验证值域，而非依赖单一的面向模型配置路径。负值、小数、负零、非有限值、不安全整数、格式错误的存储父级深度以及推导溢出均被拒绝。直接的 `SubagentStartRequest` 可以省略上限，让此机制不约束深度；经 Loader 解析的 `dsh-tool-subagent` 配置则默认值为 `3`、接受数值覆盖，并使用显式的 `'provider-managed'` 来省略由进程外提供方部署拥有递归预算时的上限。三是一个较小的有限默认值，仍允许 root 加三代后代：[SDK 辅助函数生成的 subagent 条目](../../../../packages/sdk/helper/src/features/builtin/index.ts)和 [JSON-RPC 示例](../../../../examples/jsonrpc-agent/cordis.yml)采用这项通用策略，而已交付的交互式 ACP、headless 和 REPL 示例固定为一。提供方缺少 `depthLimit` 时，数值工具上限会在提供方挂载阶段失败。
+
+部署可以组合深度与过滤，但数值上限不会合成过滤器。委派工具在上限处仍然可见，因为授权可能依赖运行时状态；每次尝试启动都会检查调用方 agent 当前的持久与运行时深度，被拒绝的启动返回错误工具结果，且不发布子 agent。可见性策略固定的部署可以另外在子 agent 中 deny 委派工具。两种选择都不改变提供方的对话历史行为。
+
+### 能力门控保持提供方诚实
+
+能力将请求的功能与提供方实现分离。`SubagentCapabilities` 声明 `persona`、`toolFilter` 和 `depthLimit`；`SubagentService.start()` 在调用提供方之前，对照这些标志检查请求中每个存在的字段。
+
+这使 spawn 和 fork 提供方可以共享进程内实现，而外部提供方只声明自己能强制执行的部分。请求永远不会静默降级：选择不受支持的控制会产生 `UNSUPPORTED_CAPABILITY`，不会有运行或生命周期事件存在。
+
+### 未发布设置使第一次请求正确
+
+所有子 agent 局部的组合在子 agent 变得可观察之前完成。进程内提供方向 agent 创建提供一个设置回调；该回调在子 agent 作用域中安装人设、工具限制和结构化输出贡献。只有设置成功后，创建才发布会话和 agent 并允许驱动器启动。
+
+设置失败会回滚私有子 agent。没有观察者能获取到一个「第一次提示词使用了部署人设或未过滤工具集、后续提示词才使用所请求配置」的子 agent。
+
+## 可见性不是授权
+
+这些控制组合的是同一可信进程内的行为，而非授权行为。`toolFilter` 改变工具注册表解析出的子 agent 视图，但它不创建父到子的授权格，不要求子 agent 仅持有父级子集授权，不沙箱化插件，也不阻止持有另一个 Cordis 上下文的代码直接调用服务。
+
+具体而言，子 agent 局部工具在全局过滤之后添加，可能不在父级视图中。仅 deny 的子 agent 也能看到 deny 列表未命名的后来全局工具。这些是有意的活组合语义，而非不可升权保证。
+
+安全设计需要独立的授权表示、传播规则和执行时强制点。创建时的授权快照、父级子集授权、显式的未来授权 API，以及通用的能力/输出/终止标签均不在本功能范围内。
+
+## 曾考虑的替代方案
+
+**为每种人设或工具集创建一个提供方。** 这会使共享相同传输和生命周期实现的提供方成倍增加，使动态部署配置变得笨拙，且仍需要递归机制。提供方的职责是执行传输；请求承载每个子 agent 的组合。
+
+**复制父级的完整工具视图。** 注册作用域设计上是扁平的，生命周期所有权不意味着可见性继承。复制已解析视图还会冻结动态全局注册，并在未完整定义任一契约的情况下混淆组合与授权。
+
+**在子 agent 创建时快照允许的全局工具。** 冻结的 allow 集合使未来注册统一不可用，但它改变了热注册语义并开启了授权设计。已实现的过滤器保持为活跃的注册表谓词，并直接记录 allow 与 deny 的行为。
+
+**仅隐藏工具 schema。** 仅呈现层的过滤让模型可以通过 Code Mode 或伪造调用执行一个提示词声称不存在的工具。改为由一个解析器同时管控呈现和执行。
+
+**把深度上限编码为自动工具过滤器。** 创建时过滤器会快照一个可能依赖运行时状态的决策，只影响一个已配置工具名，且不保护直接服务调用方或替代委派工具。提供方改为在每次启动时强制绝对上限。
+
+## 后果
+
+贡献者可以配置子 agent 的角色、可见全局工具和递归深度，而无需定义新的提供方。能力检查在所有权开始之前失败，未发布设置使第一次请求一致，单一工具解析器防止呈现/执行漂移。
+
+代价是部署方必须理解活跃的 allow/deny 行为以及可见性与授权的区别。当前深度策略禁止再创建子 agent 后，模型仍可能调用可见的委派工具并收到错误。提供方作者必须准确声明每个受支持的控制，进程内提供方必须在发布前安装所有请求的贡献。这些控制有意不解决安全隔离或父到子的不可升权问题。

-# Agent Note: Optional time-context plugin
-
-Status: implemented
-
-English | [中文](2026-07-14-time-context-plugin.zh.md)
-
-## Problem
-
-The dynamic system-prompt storage and refresh decision in this record is superseded by [Durable per-step time context](2026-07-16-durable-per-step-time-context.md). The opt-in package, zoned formatting, and validation remain; the follow-up owns the current model-visible and durability contract.
-
-An agent request has no live clock unless a deployment puts one in prompt text or gives the model a query tool. Static text becomes stale, while a tool call adds overhead to ordinary reasoning about dates, deadlines, or idle time. Without elapsed time, the model cannot distinguish an immediate follow-up from one sent hours after the preceding message.
-
-Prompt assembly can derive both facts per step from durable session timestamps, and request-header logging can record the exact rendered value. Accumulating stale readings in conversation history or waking idle agents would violate the existing request lifecycle.
-
-## Decision
-
-`@deepseek-ai/dsh-time-context` is an opt-in function plugin at `packages/context/time-context/`. The `context/` product group holds bounded request-context enrichments that define neither a tool nor a service. `dsh-agent-spine-demo` and shipped examples do not load the package; deployments mount it explicitly when its token and disclosure costs are acceptable.
-
-The plugin registers the global `context:time` system-prompt section at order 10, after the deployment persona and before tool guidance. For an active turn it emits an ISO-shaped timestamp with numeric UTC offset and IANA zone, plus a compact whole-second duration since the last model-visible message before the turn opened. Bare and idle assemblies receive an empty section.
-
-### Previous-message baseline
-
-At a turn's first assembly, the provider scans before `turn/start` for the latest `user/message`, `assistant/message`, `tool/result`, `context/message`, or `steering/message`. It excludes the current prompt so the duration expresses the inter-turn gap instead of approximately zero. Every refresh in that turn keeps the same baseline, and the first turn reports `unavailable (no earlier message in this session)`.
-
-The baseline is the session event's append time, not an unlogged client timestamp. Resume and fork behavior are therefore deterministic from the durable log, and the model-visible value remains reconstructable without a new event. A backward wall-clock adjustment clamps the duration to zero.
-
-### Refresh policy
-
-`refreshIntervalMs` defaults to 60,000 and must be a non-negative safe integer. Every turn's first request refreshes. Later assemblies in that turn reuse the block until its age reaches the interval; `0` refreshes every step. No timer creates work during model calls, tools, or idle time because refresh is request-bound.
-
-When `timeZone` is omitted, `Intl.DateTimeFormat` resolves the Node process's system zone once at plugin load. Node honors `TZ`; without that override, the host or container supplies the zone. An explicit value must be an IANA identifier and is validated at load. The captured zone remains stable until plugin reload, and the ISO-shaped local timestamp includes its current numeric offset so daylight-saving changes stay explicit. This is the deployment process's zone, not a remote user's zone.
-
-### Logging and token shape
-
-The loop records the temporal block in full `request/header` snapshots before transmission, satisfying the [reconstructable-requests contract](../architecture/2026-07-05-reconstructable-requests.md). Each request carries one current block; earlier readings do not remain in conversation history. The plugin owns the fact and contributes it through the prompt registry, following the [prompt-variables Agent Note](../architecture/2026-07-05-prompt-variables-and-tool-guidance-ownership.md) without a loop special case.
-
-## Testing
-
-Unit tests pin formatting, baselines, refresh policy, validation, per-agent state, disposal, and load-time system-zone capture. A real agent-loop test pins the transmitted prompt and full `request/header` snapshots. A keyless subprocess e2e boots a test-only `cordis.yml` through the real Loader and stdio app, omits `timeZone` under a controlled `TZ`, drives two turns, and verifies the persisted request headers externally. Default snapshot compositions omit the plugin, so their transcript fixtures contain no temporal block.
-
-## Alternatives considered
-
-- **Append a `context/message` on every turn or refresh** — rejected because readings and token cost would accumulate in history. Replacing a prior surface node would preserve its old position, while replacing the tail would hide intervening conversation.
-- **Use `agent/session-prefix`** — rejected because the session-stable prefix cannot represent a per-turn or per-step clock.
-- **Mutate requests in `agent/request`** — rejected because that seam shapes call config after the message boundary; inserted model content would bypass prompt-pressure accounting and request-header logging.
-- **Register separate `{{current_time}}` and `{{elapsed}}` variables** — rejected because independent providers can sample different instants and require shared caching. One section records the pair atomically without a deployment-authored template.
-- **Refresh from a background timer** — rejected because a new value has no consumer outside request assembly. Timer-driven `agent.inject()` would create turns and wake idle sessions merely to report time passing.
-- **Keep UTC as the omitted default** — rejected because an explicitly enabled clock should follow its deployment environment unless the operator chooses UTC. `timeZone: UTC` remains available when a deployment requires it.
-- **Add a time-zone detection library** — rejected because Node's `Intl` runtime already exposes the process's IANA zone. Another dependency cannot infer a remote user's zone either.
-- **Mount the plugin in `dsh-agent-spine-demo`** — rejected because time zone, disclosure, token budget, and freshness are deployment policy. Opt-in keeps default context stable.
-- **Place the package in `core/`** — rejected because `core/` owns the product API spine, while this plugin is an optional leaf with no service key.
-
-## Consequences
-
-- Opted-in models receive a zoned clock and inter-turn duration without a tool call. The system-prompt cost is fixed per request instead of growing with the session.
-- An omitted `timeZone` follows the process's `TZ`, host, or container zone as observed at plugin load. Operators must configure an explicit zone when the deployment environment does not represent the intended user.
-- A refresh changes the request header and can add a full `request/header` snapshot with reason `change`. `refreshIntervalMs` trades freshness against the number and size of durable full snapshots; `0` records a new value on every step whose whole-second rendering changes.
-- No request exists solely to refresh time. A long-running tool leaves the prior reading until the next step assembles.
-- Duration reflects harness processing time at durable append boundaries, not client-network latency before logging. Preserving a client-origin timestamp requires a separate durable input contract.

-# Agent Note：可选时间上下文插件
-
-Status: implemented

-## 问题
-
-本记录中的动态系统提示词存储和刷新决策已由[持久的逐步骤时间上下文](2026-07-16-durable-per-step-time-context.md)取代。需要显式启用的包（package）、分区时间格式和校验仍然保留；后续 Agent Note 负责当前的模型可见与持久性契约。
-
-如果部署方既未在提示词中提供时钟，也未给模型提供查询工具，agent（智能体）请求就无法获得实时准确的时间。静态文本会变得陈旧，而对于日期、截止时间或闲置时长等常规推理，调用工具会增加开销。缺少已经过去的时长时，模型无法区分紧接着发送的消息与上一条消息几小时后才发送的消息。
-
-提示词组装流程可以在每个步骤中根据持久会话时间戳派生这两项信息，请求头日志则可以记录实际渲染的确切值。在会话历史中累积陈旧读数或唤醒空闲 agent 都会违反现有请求生命周期。
-
-## 决策
-
-`@deepseek-ai/dsh-time-context` 是位于 `packages/context/time-context/`、需要显式启用的函数插件。`context/` 产品分组用于容纳既不定义工具、也不定义服务的有界请求上下文增强。`dsh-agent-spine-demo` 和仓库提供的示例都不会加载该包；只有当 token 与信息披露成本可接受时，部署方才显式挂载它。
-
-该插件注册顺序值为 10 的全局系统提示词区段 `context:time`，位置在部署方角色设定之后、工具指导之前。对于活跃轮次，它会输出带数字 UTC 偏移和 IANA 时区、形似 ISO 的时间戳，以及从轮次开始前最后一条模型可见消息起算的紧凑整秒时长。未绑定 agent 或 agent 处于空闲状态时，该区段为空。
-
-### 上一条消息基线
-
-在轮次首次组装时，提供方会在 `turn/start` 之前查找最近的 `user/message`、`assistant/message`、`tool/result`、`context/message` 或 `steering/message`。它会排除当前提示词，使时长表达轮次间隔，而不是接近零。同一轮次中的每次刷新都保留这条基线；首个轮次报告 `unavailable (no earlier message in this session)`。
-
-基线采用会话事件的追加时间，而不是日志中不存在的客户端时间戳。因此，恢复和 fork 行为可以从持久日志中确定性重现，模型可见值也无需新增事件即可重建。系统挂钟向后调整时，插件会将时长钳制为零。
-
-### 刷新策略
-
-`refreshIntervalMs` 默认值为 60,000，并且必须是非负安全整数。每个轮次的首次请求都会刷新。同一轮次中的后续组装会复用该区块，直至其存在时间达到该间隔；设为 `0` 时每个步骤都刷新。刷新仅由请求驱动，因此在模型调用、工具运行或空闲期间，计时器不会创建任务。
-
-省略 `timeZone` 时，`Intl.DateTimeFormat` 会在插件加载时解析一次 Node 进程的系统时区。Node 会遵循 `TZ`；没有该覆盖值时，时区由主机或容器提供。显式值必须是 IANA 标识符，并在加载时接受校验。捕获的时区在插件重新加载前保持稳定，形似 ISO 的本地时间戳包含其当前数字偏移，使夏令时变化保持显式可见。该默认值代表部署进程的时区，而不是远程用户的时区。
-
-### 日志与 token 形态
-
-agent loop（智能体循环）会在发送前通过完整的 `request/header` 快照记录时间区块，从而满足[可重建请求契约](../architecture/2026-07-05-reconstructable-requests.md)。每个请求只携带一个当前区块；先前的读数不会保留在会话历史中。该插件拥有时间信息，并按照[提示词变量 Agent Note](../architecture/2026-07-05-prompt-variables-and-tool-guidance-ownership.md)通过提示词注册表贡献该信息，无需为循环添加特殊分支。
-
-## 测试
-
-单元测试固定格式化、基线、刷新策略、校验、逐 agent 状态、资源释放行为，以及系统时区在加载时的捕获行为。使用真实 agent loop 的测试固定实际发送的提示词和完整的 `request/header` 快照。无密钥子进程端到端测试通过真实 Loader 和 stdio 应用启动测试专用 `cordis.yml`，在受控 `TZ` 下省略 `timeZone`，驱动两个轮次，并从外部校验持久请求头。默认快照组合不包含该插件，因此其中的 transcript（文本记录）fixture（测试前置数据）不包含时间区块。
-
-## 考虑过的替代方案
-
-- **每个轮次或每次刷新都追加一条 `context/message`**——不予采纳，因为读数和 token 成本会在历史中累积。替换先前的表层节点会保留其旧位置，而替换尾部节点会隐藏中间的会话内容。
-- **使用 `agent/session-prefix`**——不予采纳，因为会话期间保持稳定的前缀无法表示逐轮次或逐步骤变化的时钟。
-- **在 `agent/request` 中修改请求**——不予采纳，因为该边界在消息边界之后塑造调用配置；插入模型可见内容会绕过提示词压力核算和请求头日志。
-- **注册独立的 `{{current_time}}` 和 `{{elapsed}}` 变量**——不予采纳，因为独立提供方可能在不同时间点采样，并且需要共享缓存。单个区段会以原子方式记录两项信息，也不需要部署方编写时间模板。
-- **通过后台计时器刷新**——不予采纳，因为请求组装之外没有消费新值的对象。由计时器驱动 `agent.inject()` 会创建轮次，并且只为报告时间流逝就唤醒空闲会话。
-- **省略配置时仍默认使用 UTC**——不予采纳，因为显式启用的时钟应跟随部署环境，除非运维方选择 UTC。需要 UTC 的部署仍可配置 `timeZone: UTC`。
-- **引入时区探测库**——不予采纳，因为 Node 的 `Intl` 运行时已经能够提供进程的 IANA 时区，而且额外依赖同样无法推断远程用户的时区。
-- **在 `dsh-agent-spine-demo` 中挂载插件**——不予采纳，因为时区、信息披露、token 预算和新鲜度都属于部署策略。选择加入能保持默认上下文稳定。
-- **将包放入 `core/`**——不予采纳，因为 `core/` 负责产品 API 主干，而该插件是没有服务键的可选叶节点。
-
-## 后果
-
-- 选择加入的模型无需调用工具，即可获得分区时钟和轮次间隔时长。每个请求的系统提示词成本固定，不会随会话增长。
-- 省略 `timeZone` 时，插件采用加载时观察到的进程 `TZ`、主机或容器时区。当部署环境不能代表目标用户时，运维方必须显式配置时区。
-- 刷新会改变请求头，并可能新增一份 reason 为 `change` 的完整 `request/header` 快照。`refreshIntervalMs` 用新鲜度换取完整持久快照的数量与大小；设为 `0` 时，每个整秒渲染结果发生变化的步骤都会记录新值。
-- 系统不会仅为刷新时间而创建请求。长时间运行的工具会保留先前读数，直至下一步骤开始组装。
-- 时长反映持久追加边界处的 harness 处理时间，不包含消息进入日志之前的客户端网络延迟。若要保留客户端来源时间戳，需要单独的持久输入契约。

## Decision
-`@deepseek-ai/dsh-time-context` is an opt-in function plugin in `packages/context/time-context/`. It registers a prepended `agent/pre-step` listener and, when an injection is due, calls `agent.inject()` for a pre-step attempt whose signal is not already aborted. The injected `context/message` carries source `{ kind: 'plugin', plugin: 'time-context' }` and append surface metadata; a suppressed attempt appends nothing.
+`@deepseek-ai/dsh-time-context` is an opt-in function plugin in `packages/context/time-context/`. The `context/` group holds bounded request-context enrichments that define neither a tool nor a service, and shipped examples do not mount this plugin because its time-zone disclosure and token cost are deployment policy. It registers a prepended `agent/pre-step` listener and, when an injection is due, calls `agent.inject()` for a pre-step attempt whose signal is not already aborted. The injected `user/message` carries source `{ kind: 'plugin', plugin: 'time-context' }` and append surface metadata; a suppressed attempt appends nothing.
The listener records preparation context before a possible `step/start`. Its prepended registration runs before ordinary automatic compaction listeners, so pressure estimation and any resulting surface rewrite observe a newly appended reading. A later pre-step listener can cancel or fail the attempt before the step opens; the reading remains because the durable log is append-only and this plugin performs no rollback.
The optional `timeZone` config resolves the Node process's IANA zone once at plugin load when omitted; an explicit value is validated by `Intl.DateTimeFormat`. The timestamp includes the numeric UTC offset and resolved IANA zone.
-The optional `refreshIntervalMs` config is manually validated at plugin load as a non-negative safe integer. Omission or `0` injects on every eligible preparation attempt. A positive value scans the raw session events for the most recent `context/message` with this plugin's source and injects when none exists, wall time moved backward, or the event is at least the configured age. The raw event timestamp governs even after compaction shadows the message, so scheduling persists across turns and process resume without a timer or process-local cache.

- **Inject from a background timer** — rejected because idle time has no pending request to consume the value, and timer-driven injection would create durable turns solely to report time passing.
- **Expose time only through a tool** — rejected because ordinary temporal reasoning would require an avoidable tool round trip and would not guarantee a reading before every step.
- **Use `agent/session-prefix`** — rejected because one loop-instance prefix cannot represent distinct step timestamps and does not accumulate historically attributable readings.
+- **Mutate assembled requests or register independent prompt variables** — rejected because request-local insertion bypasses the durable surface and separate providers can sample different instants. One attributed context message records the timestamp and elapsed baseline atomically.
+- **Default to UTC or add a time-zone detection dependency** — rejected because an explicitly mounted plugin follows its process environment unless the operator selects an IANA zone, while no server-side library can infer a remote user's zone.
+- **Mount the plugin in shipped compositions or place it in `core/`** — rejected because disclosure, time zone, freshness, and history cost are deployment choices for an optional context leaf, not product-spine policy.
## Consequences
- Omission or `0` records every eligible preparation attempt; a positive interval reduces append frequency and history growth while preserving durable scheduling across resume.
- Timing context remains append-only until compaction shadows older surface nodes, including a preparation reading left by a later cancellation or failure.
- The first-step duration normally measures from the prompt that opened the turn, while later-step durations measure model and tool processing since the preceding step context.
-- An omitted `timeZone` still reflects the deployment process rather than a remote user, and elapsed time still uses durable harness append boundaries rather than client-origin timestamps.

Focused real-stack tests additionally cover completion, blocker and round-limit outcomes, malformed and oversized reports, ordinary child failure with the last good handoff, one phase event, and cancellation to child quiescence. Package sources remain under the repository's per-file 100% coverage gate, and built-binary tests cover installed-artifact resolution. The implementation experience is recorded in the root testing policy: every non-trivial model- or human-visible change must carry a real-example keyless snapshot in the same PR rather than relying on package-only or mock-only fixture coverage.

- **No goal reflector** — concern events, automatic no-progress heuristics, goal revision by an independent reflector, stuck-pattern detection, and `loop_split` are not implemented. Humans can edit, pause, clear, or resume the goal directly.
- **Ralph policy remains narrow** — one round creates one fresh child; within-round fan-out, evaluator/worker role separation, dynamic provider/model selection, and structural recursive-Ralph tool denial need separate policy surfaces. Prompt guidance is not enforcement.
- **Ralph does not retry a failed child** — an ordinary failure preserves the failed round and last good handoff, while fatal workflow infrastructure failures can end before that state is available. Retry count, backoff, and richer failure transport need separate policy and seam design.

The selected front door receives the exact generated or resumed `SessionId` used by the pre-created agent.

A matching `agent-loop/config-start-failed` event is therefore reported before screen takeover and exits with status 1.

## Problem
-The TUI owns seven slash commands, while ACP defines a standard command catalog and invocation shape. Keeping command names, help text, autocomplete, dispatch, and cancellation inside each adapter makes every new command an adapter edit, prevents optional plugins from contributing commands, and lets the two front doors drift. Treating slash input as an ordinary model prompt is also unsafe: a user-visible direct action can unexpectedly consume tokens or let the model reinterpret an unknown command.

## Decision
-`@deepseek-ai/dsh-commands` in `packages/ui/commands/` is the product command registry. The terminal and ACP app bundles mount it beside their consuming front door, and the SDK project helper emits the same service when scaffolding ACP directly; the executor-less, UI-less agent spine remains independent. TUI and ACP inject the service, while command producers depend only on the registry and any domain they operate.

### Registry contract
-A `CommandDefinition` contains a lowercase name without `/`, a non-empty description, an optional unstructured-input hint, and an abortable handler. Registration validates and detaches the metadata, freezes the effective definition, and returns the exact Cordis effect disposer. Duplicate names fail within one layer. Every adapter consuming the registry sees every effective definition; a command plugin that cannot operate in a deployment omits its registration there instead of encoding adapter identities in the shared domain.

### TUI mapping
-The TUI registers `help`, `clear`, `cancel`, `reasoning`, `tools`, `redraw`, and `exit` as agent-scoped command definitions instead of switching on strings.

+The TUI registers its built-in slash commands as agent-scoped command definitions instead of switching on strings. Its autocomplete and help view read the live catalog, so plugin commands appear and disappear with their effects. Any submitted line beginning with `/` stays in the command plane; unknown input produces a terminal warning rather than falling through to `Agent.send()` or `Agent.steer()`.
Each submitted command owns an `AbortController`. TUI disposal aborts outstanding dispatches, removes the local definitions, and waits for the command-producing fiber before completing teardown.
-### ACP mapping
-
-The bridge follows the current [ACP v1 slash-command contract](https://agentclientprotocol.com/protocol/v1/slash-commands). `session/new` and `session/load` emit the exact agent's full `available_commands_update` snapshot; a new session's RPC response introduces its server-generated id before the snapshot is enqueued. Every registry change emits a replacement snapshot for each live session. Names, descriptions, and optional unstructured-input hints map directly to `AvailableCommand`.
-
-ACP permits a command prompt to contain additional supported content blocks. The bridge applies its ordinary lossless `text` and `resource_link` flattening, then enters the command plane when the result starts with `/`. Unsupported prompt blocks are rejected by the existing capability boundary. Known commands execute directly; unknown or malformed slash input returns a direct error and never reaches the model. Successful text, expected errors, and thrown-failure diagnostics stream as live `agent_message_chunk` output and settle `end_turn`.
-
-One model prompt or direct command may be in flight per ACP session, independently across sessions. `session/cancel` aborts the direct command when one owns the request; it calls `Agent.cancel()` only for an agent prompt, so cancelling a command cannot destroy unrelated queued or injected agent work. Connection teardown aborts commands and then disposes the owned agents.
-
## Testing
The registry suite covers syntax boundaries, immutable normalization, runtime metadata validation, deterministic sorting, global and scoped shadowing, duplicate rejection, exact disposal, contained change-notification failures, direct invocation, expected and malformed results, synchronous and asynchronous failure, and every abort timing edge at per-file 100% statement, branch, function, and line coverage.
-TUI tests exercise all migrated built-ins, live plugin discovery, help/autocomplete refresh, direct results, unknown-command rejection, raw-input delivery, definition removal, startup rollback, and disposal cancellation. ACP tests use the real SDK connection, agent factory, loop, and JSONL persistence to verify create/load snapshots, dynamic updates, scoped multi-session catalogs, supported-block flattening, direct success/error/failure, unknown-command isolation, cancellation, and the absence of model requests or session messages. The SDK helper suite pins direct-ACP composition. Keyless ACP and terminal snapshots pin the new protocol and rendered transcript shapes.

+- **Keep adapter-local switches** — rejected because optional plugins cannot contribute discovery and behavior without editing the TUI.
- **Represent human commands as model tools** — rejected because discovery and direct invocation are human UI behavior; routing through the model adds latency, token cost, and reinterpretation.
-- **Put the registry in the core agent spine** — rejected because headless and JSON-RPC agents do not consume it, while the two UI app bundles can compose it explicitly.
+- **Put the registry in the core agent spine** — rejected because UI-less front doors do not consume it, while TUI can compose it explicitly.
- **Make `dsh-agent-loop` inject commands** — rejected because the loop does not execute or discover human commands. Agent-scoped producers declare the UI dependency in a child plugin instead.
- **Attach adapter masks to each definition** — rejected because support is a composition fact, not command-domain state. Every composed adapter exposes a registered command; an incompatible plugin omits registration in that deployment.
- **Send unknown slash input to the model** — rejected because typoed or unavailable direct actions must fail predictably rather than change execution planes.
- **Persist generic command input and output** — rejected because adapter notices are not model-visible state. A handler that changes durable behavior calls the owning domain API, which records its own events.
-- **Restrict ACP commands to one text block** — rejected because ACP v1 permits accompanying content; the bridge already has a lossless accepted-block translation.
## Consequences

+- Command producers are ordinary removable plugins, and TUI consumes their validated catalog and dispatch contract.

- Direct command cancellation is isolated from model-turn cancellation.
## Known limitations and deferred work

-
-ACP 允许命令提示携带额外的受支持内容块。桥接应用普通的无损 `text` 与 `resource_link` 扁平化，然后在结果以 `/` 开头时进入命令平面。不支持的提示块由现有能力边界拒绝。已知命令直接执行；未知或格式错误的斜杠输入返回直接错误，绝不会到达模型。成功文本、预期错误和抛出失败的诊断作为实时 `agent_message_chunk` 输出流式发送，并以 `end_turn` 结束请求。
-
-每个 ACP 会话同时只能有一个模型提示或直接命令进行中，各会话彼此独立。当直接命令拥有请求时，`session/cancel` 会中止它；只有智能体提示才调用 `Agent.cancel()`，因此取消命令不会销毁无关的排队或注入智能体工作。连接清理会先中止命令，再释放所拥有的智能体。

-# Agent Note: Startup slogans replace the configured TUI welcome line
-
-Status: implemented
-
-English | [中文](2026-07-20-tui-startup-slogans.zh.md)
-
-> **Superseded** for the slogan/animation half by the [banner sweep Agent Note](2026-07-21-tui-banner-sweep.md): the slogan bank and typewriter reveal shipped, read as weird in use, and were replaced by a subtitle-free banner with a whole-banner sweep. The removal of the configured demo welcome and the animation-lifecycle groundwork (start after `ui.start()`, clear through `detachListeners`) stand.
-
-## Problem
-
-The TUI header subtitle came from a `welcome` config the demo leaf set to "TUI agent ready. Give it a coding task." — instructional filler that told a returning user nothing, restated what the product is on every boot, and had a hardcoded twin (`'ready.'`) as the schema default in two packages. The product wanted a startup moment with some character instead of a static banner caption.
-
-## Decision
-
-- `examples/tui-agent/cordis.yml` no longer configures `welcome`; the config key stays for deployments and fixtures that need a fixed, deterministic subtitle (the Code Mode overlay and every snapshot/scripted fixture keep theirs).
-- When `welcome` is unset, `dsh-tui` picks one member of an exported `STARTUP_SLOGANS` bank per boot (`pickStartupSlogan`, injectable random source) and reveals it with a typewriter animation: one character per 40 ms frame, a `▌` block cursor trailing until complete. The reveal starts only after `ui.start()` succeeds and its interval is cleared on dispose alongside the other listeners.
-- The slogan bank is presentation copy, deliberately not config: deployments that want controlled wording already have `welcome`. Slogans are ASCII-only by contract because the reveal slices per character.
-- `dsh-tui-demo` forwards `welcome` only when configured instead of defaulting it, so the app no longer decides the TUI's idle subtitle.
-- The keyless PTY boot scenario now waits for the reveal cursor (`▌` — the only source of that glyph in an empty transcript) instead of the removed welcome text.
-
-The same change restores `packages/ui/tui/src/index.ts` to 100 % per-file coverage, which the color-scheme merge had broken on the integration branch: the editor border-color reassignment inside `applyColorScheme` was dead (the `setStatus` call right after re-derives it) and is removed, and the color-scheme query's `.then`/`.catch` arrows became named, tested handlers (`applyReportedScheme`, `ignoreSchemeQueryFailure` — the latter pinned by a test whose terminal throws on the DSR query write).
-
-## Alternatives considered
-
-**A fixed cooler slogan.** Rejected: one string re-read on every boot decays into wallpaper exactly like the line it replaces; a small rotating bank keeps the moment alive at no complexity cost.
-
-**Making the bank and reveal speed configurable.** Rejected: that is two new knobs for presentation copy; `welcome` is already the escape hatch for deployments with an opinion, and the no-hardcoded-tunables rule targets deployment-varying behavior, not brand copy.
-
-**Animating in `HeaderComponent` itself.** Rejected: the component would need a TUI handle and its own lifecycle; the chat already owns a render loop, timers, and a disposal path, so the reveal lives beside the other `createTuiChat` effects and `detachListeners` clears it.
-
-## Consequences
-
-- Boot output is no longer byte-deterministic when `welcome` is unset (random slogan, timed frames). Every recorded or snapshot surface pins `welcome` explicitly, so no snapshot changed; the PTY smoke anchors on the reveal cursor and the session-id line instead.
-- The `welcome` schema default disappeared from both `dsh-tui` and `dsh-tui-demo`; a direct caller passing no welcome now gets a slogan, not `'ready.'`.
-- Adding a slogan is a one-line bank edit; tests assert membership, not specific text.
-
-## Testing
-
-`packages/ui/tui/tests/tui.spec.ts` pins deterministic bank selection with an injected random source, the reveal (a bank member fully rendered, cursor frames observed), the configured-welcome path rendering verbatim with no cursor, and dispose stopping a mid-reveal animation. `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` boots the real tree in a PTY and waits on the reveal cursor. Verified live in tmux (mid-reveal frame `no map below▌` then the full slogan).

-# Agent Note: 启动 slogan 取代配置化的 TUI 欢迎语

-
-> **已被取代**：slogan/动画的那一半由[横幅扫入 Agent Note](2026-07-21-tui-banner-sweep.md)取代：slogan 库和打字机动画上线后实际使用中显得怪异，已替换为无副标题的横幅加整体扫入。移除示例配置中欢迎语的决定与动画生命周期基础设施（`ui.start()` 后启动、经 `detachListeners` 清除）保持不变。
-
-## Problem
-
-TUI 头部副标题来自一个 `welcome` 配置，示例叶子配置把它设为 "TUI agent ready. Give it a coding task."——一句说明书式的填充语，对老用户毫无信息量，每次启动都在复述产品是什么，而且它还有一个硬编码的孪生兄弟（`'ready.'`）作为两个包里的 schema 默认值。产品需要的是一个有性格的启动时刻，而不是一条静态横幅说明。
-
-## Decision
-
-- `examples/tui-agent/cordis.yml` 不再配置 `welcome`；该配置键保留给需要固定、确定性副标题的部署与 fixture（Code Mode overlay 和所有快照/脚本化 fixture 都保留各自的欢迎语）。
-- `welcome` 未设置时，`dsh-tui` 每次启动从导出的 `STARTUP_SLOGANS` 库里挑选一条（`pickStartupSlogan`，随机源可注入），并以打字机动画逐字显示：每帧 40 ms 一个字符，完成前尾随一个 `▌` 块状光标。动画只在 `ui.start()` 成功后启动，其定时器与其他监听器一起在 dispose 时清除。
-- slogan 库是展示文案，刻意不做成配置：想控制措辞的部署已经有 `welcome` 这个出口。按契约 slogan 只含 ASCII，因为逐字显示按字符切片。
-- `dsh-tui-demo` 只在配置了 `welcome` 时才转发它，不再填默认值，应用不再替 TUI 决定空闲副标题。
-- 无 key 的 PTY 启动场景改为等待逐字显示的光标（`▌`——空 transcript 里该字形的唯一来源），不再等待已删除的欢迎文本。
-
-同一变更把 `packages/ui/tui/src/index.ts` 恢复到 100% 的单文件覆盖率（颜色方案合并曾在集成分支上破坏它）：`applyColorScheme` 里对编辑器边框颜色的重新赋值是死代码（紧随其后的 `setStatus` 调用会重新推导它），已删除；颜色方案查询的 `.then`/`.catch` 箭头函数改为具名、有测试的处理器（`applyReportedScheme`、`ignoreSchemeQueryFailure`——后者由一个让终端在 DSR 查询写入时抛错的测试固定）。
-
-## Alternatives considered
-
-**换一条更酷的固定 slogan。** 否决：一条每次启动都重读的字符串会和它取代的那行一样退化成墙纸；一个小的轮换库以零复杂度代价让这个时刻保持新鲜。
-
-**把 slogan 库和显示速度做成配置。** 否决：那是为展示文案新增两个旋钮；对措辞有主张的部署已经有 `welcome` 这个出口，而「插件里不许硬编码可调参数」规则针对的是随部署变化的行为，不是品牌文案。
-
-**在 `HeaderComponent` 内部做动画。** 否决：组件将需要持有 TUI 句柄和自己的生命周期；聊天层已经拥有渲染循环、定时器和释放路径，所以逐字显示与 `createTuiChat` 的其他资源放在一起，由 `detachListeners` 清除。
-
-## Consequences
-
-- `welcome` 未设置时启动输出不再字节级确定（随机 slogan、定时帧）。所有录制或快照表面都显式固定 `welcome`，因此没有快照变化；PTY 冒烟测试改为锚定逐字显示光标和会话 id 行。
-- `welcome` 的 schema 默认值从 `dsh-tui` 和 `dsh-tui-demo` 中消失；不传 welcome 的直接调用方现在得到的是 slogan，而不是 `'ready.'`。
-- 新增一条 slogan 只需在库里加一行；测试断言成员归属，不断言具体文本。
-
-## Testing
-
-`packages/ui/tui/tests/tui.spec.ts` 固定以下行为：注入随机源后的确定性选取、逐字显示（库中某条完整渲染、观察到光标帧）、配置了 welcome 时逐字动画不启动且原文渲染、以及 dispose 停止进行中的动画。`examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` 在 PTY 里启动真实配置树并等待显示光标。已在 tmux 中实机验证（中途帧 `no map below▌`，随后是完整 slogan）。

Encoding host markup directly into the agent message contract would also bind the core loop to one UI syntax.
## Decision
`@deepseek-ai/dsh-session-reference` is one context consumer service at `ctx.sessionReferences`. Hosts normalize their protocol into `SessionReferenceInput[]`, call `prepare()` before enqueue, and pass the returned contexts through the generic `SendOptions.contexts` boundary. Core agent packages know only that one queued message may carry frozen `HookContext[]`; they do not parse session URIs or read another log.
-`dsh-session:<base64url(JSON.stringify(sessionId))>` is the canonical host-independent identifier. JSON string encoding precedes base64url so quotes, slashes, backslashes, Unicode, newlines, and every other JavaScript string value round-trip without delimiter ambiguity. TUI renders that URI inside `@[label](uri)` and ACP uses standard `resource_link`; text-only clients may use the same inline mention. Explicit Markdown mentions and resource links reject malformed URIs. Bare text becomes a reference only for a non-empty base64url-shaped payload, whose decode must still be canonical; empty or punctuation-only uses remain ordinary discussion text.

The service uses `ctx.sessionQuery.readSurface(sessionId)`, which loads one live-preferred corpus observation, folds it with the session package's canonical surface algorithm, and returns a detached header, capture seq, and current nodes. FTS is not a dependency: v1 discovery filters only id and cwd, and future title/body search can replace the candidate layer without changing reference identity or preparation.

`send()` and `steer()` snapshot content, resolved source, and contexts together as one deeply frozen lossless-JSON inbox record. Synthetic `inject()` accepts source and model-hidden metadata but not attached contexts, which belong to inbox messages. A claimed ordinary message exposes its attached contexts as the default `agent/prompt-submit` additional contexts; a block writes neither user message nor contexts. The waterfall's returned allow is authoritative, so a listener wrapping `next()` preserves downstream content and contexts unless it intentionally replaces them. After admission, absent or `separate` placement writes an independent `context/message`, while `prompt-prefix` placement bakes context and the effective request into one prompt event. Drained steering bypasses `agent/prompt-submit` but applies the same placement split. Late steering retains the same record when converted to queued input, while cancellation, disposal, and terminal discard drop message and contexts together. `agent/queued` reports the frozen contexts so the observation event describes the complete retained item.
-This preserves host driving semantics: TUI decides `send()` versus `steer()` from the agent state after preparation, so only its queued path dispatches UserPromptSubmit hooks; ACP continues to call `send()` once per `session/prompt`. Reference preparation is not a new steering protocol and does not create a turn by itself.
+This preserves host driving semantics: TUI decides `send()` versus `steer()` from the agent state after preparation, so only its queued path dispatches UserPromptSubmit hooks. Reference preparation is not a new steering protocol and does not create a turn by itself.
## Host adapters
TUI combines session candidates with the existing `@` file provider. Each candidate displays the latest folded session title and falls back to the session id; lookup follows the editor's cancellation signal, and session id, cwd, and mention labels escape external terminal controls while the canonical URI retains the original id. TUI prepares only submissions containing structured mentions, disables duplicate submit while awaiting snapshots, restores failed input, renders the prompt envelope's display content as the user message, and renders its session-reference metadata as a compact source list instead of exposing the complete JSON in the terminal.
-ACP detects direct slash commands from ordinary prompt flattening before extracting `dsh-session:` resource links and canonical inline mentions, so URI-shaped command arguments remain opaque while ordinary resource-link rendering is preserved. Standard `session/list` exposes each loadable session's folded title and, when references are mounted, a canonical URI under `_meta["deepseek-harness/sessionReference"]`; a client can use `title ?? sessionId` as the resource-link name. A valid reference without the optional service returns a capability-unavailable RPC error, and preparation failure occurs before the in-flight turn slot and agent send. A preparation-specific abort owner makes `session/cancel` and bridge teardown stop pending reads. Picker UI remains an ACP client responsibility because ACP does not define a cross-session mention menu.

## Consequences
-The new plugin is the stable semantic boundary and adds no persistence schema, event type, FTS dependency, source subscription, or compact shadow access. Standard TUI/ACP demo bundles mount it explicitly and expose its count and per-source byte limits in their own config; custom hosts remain unchanged until they mount the service and adapt their input. Reference contexts increase target history size within configured bounds and can later be summarized by ordinary target compaction, after which the source session is irrelevant.

## 决策
`@deepseek-ai/dsh-session-reference` 是注册在 `ctx.sessionReferences` 上的单一上下文消费服务。宿主先把各自的协议规范化为 `SessionReferenceInput[]`，在入队前调用 `prepare()`，再通过通用的 `SendOptions.contexts` 边界传递返回的上下文。核心 agent 包只知道一条排队消息可以携带已冻结的 `HookContext[]`；它们既不解析会话 URI，也不读取其他日志。
-`dsh-session:<base64url(JSON.stringify(sessionId))>` 是与宿主无关的规范标识符。系统先执行 JSON 字符串编码，再执行 base64url 编码，因此引号、正斜杠、反斜杠、Unicode、换行符以及其他任意 JavaScript 字符串值都能无损往返，不会因分隔符产生歧义。TUI 把该 URI 渲染到 `@[label](uri)` 中，ACP 使用标准 `resource_link`；纯文本客户端可以使用同一种行内提及标记。显式 Markdown 提及标记与资源链接会拒绝格式错误的 URI。裸文本只有在负载非空且形状符合 base64url 时才会成为引用，而且解码过程仍须通过规范性校验；空负载或只含标点符号的用法仍按普通讨论文本处理。

`send()` 与 `steer()` 会把内容、解析后的来源和上下文一起快照为一条深度冻结、无损 JSON 的收件箱记录。合成的 `inject()` 接受来源和模型不可见的元数据，但不接受附加上下文，因为上下文属于收件箱消息。普通消息被认领后，其附带的上下文会作为 `agent/prompt-submit` 的默认附加上下文公开；提示词被阻止时，系统既不写入用户消息，也不写入上下文。waterfall（瀑布式事件）返回的 allow 结果具有最终权威性，因此监听器包装 `next()` 时会保留下游内容与上下文，除非它有意替换这些值。消息被接纳后，未指定放置方式或指定为 `separate` 时会写入独立的 `context/message`；指定为 `prompt-prefix` 时则会把上下文与最终生效的请求合并写入同一个提示词事件。排空 steering 消息时会绕过 `agent/prompt-submit`，但采用相同的放置方式分流。延迟到达的 steering 转换为排队输入时保留同一条记录；取消、dispose（资源释放）和到达终止态后的丢弃则会同时丢弃消息与上下文。`agent/queued` 会报告已冻结的上下文，使观察事件能够描述完整的保留项。

TUI 把会话候选与现有 `@` 文件提供方组合在一起。每个候选项显示最新折叠后的会话标题，没有标题时回退到 session id。候选查询遵循编辑器的取消信号；session id、cwd 和提及标签中的外部终端控制字符会被转义，但规范 URI 仍保留原始 id。TUI 只准备包含结构化提及标记的提交；等待快照时禁用重复提交；失败时恢复输入；它把提示词封套的显示内容渲染为用户消息，并把其中的会话引用元数据渲染为精简的来源列表，不在终端中暴露完整 JSON。
-ACP 先从普通提示词扁平化结果中检测直接斜杠命令，再提取 `dsh-session:` 资源链接和规范的行内提及标记，因此形如 URI 的命令参数保持不透明，同时保留普通资源链接的渲染方式。标准 `session/list` 会公开每个可加载会话折叠后的标题；挂载会话引用功能时，还会在 `_meta["deepseek-harness/sessionReference"]` 下公开规范 URI。客户端可以使用 `title ?? sessionId` 作为资源链接名称。若引用有效但可选服务未挂载，系统会返回「功能不可用」RPC 错误；准备失败会发生在占用进行中轮次槽位并调用 agent send 之前。引用准备过程单独拥有中止控制权，因此 `session/cancel` 和桥接释放都能停止待处理的读取。选择器 UI 仍由 ACP 客户端负责，因为 ACP 未定义跨会话提及菜单。

-# Agent Note: Auto-titled terminal from the first message

-Status: implemented

-English | [中文](2026-07-21-tui-auto-pane-title.zh.md)
-
-> **Superseded** by the [session-title consolidation Agent Note](../simplification/2026-07-22-tui-titles-from-session-title-service.md): the TUI-local `autoTitle` generation is removed; titles come from the log-backed session-title service, and the terminal rename consumes `session/title` events.
-
-> **Superseded** for the default and the resume behavior by the [auto-title default-on Agent Note](2026-07-21-tui-auto-title-default-on.md): `autoTitle` now defaults on, and a resumed session re-derives its title from the stored first message instead of keeping the static one. The OSC 0 path, the one-shot latch, the model-summary shape, the fire-and-forget call, and every failure fallback below stand.
-
-## Problem
-
-The TUI's terminal title is a single static string (`title`, default `DeepSeek Harness`) shared by every session. A user who runs one agent per tmux pane or terminal tab sees the same label on all of them, so panes are indistinguishable at a glance and the tab bar carries no signal about what each session is doing.
-
-## Decision
-
-- `TuiConfig` gains an `autoTitle` boolean (default `false`). When it is on, the TUI issues one background model call after the first user message of a fresh session and replaces the terminal title with a short, model-generated label; the static `title` is the pre-title and the fallback.
-- The label is a model summary, not a truncation of the prompt. The request carries a fixed task instruction (summarize the request as a short title of two to five lowercase words, no punctuation) plus the user's first message and no tools; the TUI takes the first non-empty line of the reply and caps it at 40 characters (39 plus an ellipsis).
-- The title is set through `runtime.terminal.setTitle`, the same OSC 0 path the static `title` already uses. No new terminal-control surface is introduced, and pi-tui keeps ownership of terminal writes.
-- The call is fire-and-forget and one-shot per session. A `titleSettled` latch guards it: with `autoTitle` off it is pre-settled and never runs; on a resumed session whose first `user/message` is already logged it is pre-settled so the static title stands; a whitespace-only first message is skipped without consuming the slot. Any failure, an empty reply, a missing `llm` service, or a missing agent provider/model leaves the static title untouched. A dedicated `AbortController` cancels an in-flight request on shutdown.
-- The title call reaches `ctx.llm.stream` directly rather than through `agent.send`, so it never appends to the session or transcript and cannot perturb the agent loop.
-- The feature defaults off and is enabled only in the interactive product config (`examples/tui-agent/cordis.yml`) and the scripted PTY fixture. Enabling it in the shared `dsh-tui-demo` schema default would fire an extra model call in keyless replay and boot scenarios that send no user message.
-
-## Alternatives considered
-
-**Truncate the first user message instead of a model title.** Rejected: the user chose a short model-made label; a truncated raw prompt is noisy, often begins with boilerplate, and rarely reads as a title.
-
-**Rename the window (OSC 2) or the tmux window.** Rejected: OSC 0 sets only `pane_title`, so it labels the pane without renaming or leaking into the user's window title; the user confirmed OSC is the right lever.
-
-**Default the feature on.** Rejected: enabling it in the shared demo schema perturbs keyless replay and boot snapshots and spends a model call on every fresh session; opt-in per deployment keeps the default surface inert.
-
-**Fold this into the log-backed session-title work (PR #451).** Rejected: that change is session metadata persisted to the log; this is a terminal label with no persistence. Keeping them independent leaves each self-contained and avoids a shared dependency.
-
-**Block the first turn until the title resolves.** Rejected: awaiting the title before sending the user's message adds latency to the actual request; fire-and-forget makes the rename invisible to the turn.
-
-## Consequences
-
-- When enabled, a fresh session spends one extra, tool-less model call with a single short user message and a few output tokens; off by default, it costs nothing.
-- Because the title call stamps `sessionId`, it shares the session's `llm-replay` cursor: enabling `autoTitle` in a replay-backed snapshot scenario would consume a recorded script entry. This is why the default is off and the scripted PTY fixture answers the call with a tool-branching adapter rather than replay.
-- `packages/ui/tui/tests/tui.spec.ts` pins the behavior with a mock `llm` adapter: a generated title replaces the static one, over-long output is truncated with an ellipsis, a whitespace-only first message keeps the one-shot slot, empty or failing replies leave the title, a resumed session never fires, and the feature-off / no-service / missing-provider / missing-model paths keep the static title. A shutdown test asserts the in-flight request is aborted.
-- `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` proves the real Loader-booted path: the scripted adapter answers the tool-less title call with a fixed string, and the conversation scenario asserts the OSC 0 sequence reaches the PTY. Boot scenarios send no user message, so they never fire the call.

-# Agent Note: 从首条消息自动命名终端
-
-Status: implemented
-
-[English](2026-07-21-tui-auto-pane-title.md) | 中文
-
-> **已被取代**：见[标题归一 Agent Note](../simplification/2026-07-22-tui-titles-from-session-title-service.md)。TUI 本地的 `autoTitle` 生成已移除；标题来自日志承载的 session-title 服务，终端重命名消费 `session/title` 事件。
-
-> **已被取代**（就默认值与恢复行为而言），见[自动标题默认开启 Agent Note](2026-07-21-tui-auto-title-default-on.md)：`autoTitle` 现默认开启，恢复会话会从已存储的首条消息重新推导标题，而非保留静态标题。下文的 OSC 0 路径、一次性门闩、模型概括形态、发出后不等待其返回的调用，以及每一条失败兜底，均仍然成立。
-
-## Problem
-
-TUI 的终端标题是一个所有会话共用的静态字符串（`title`，默认 `DeepSeek Harness`）。在 tmux 每个窗格或每个终端标签页各跑一个 agent（智能体）的用户看来，它们的标签全都一样，因此窗格一眼看去无从区分，标签栏也不携带任何关于各会话正在做什么的信号。
-
-## Decision
-
-- `TuiConfig` 新增布尔字段 `autoTitle`（默认 `false`）。开启后，TUI 会在全新会话的首条用户消息之后发起一次后台模型调用，并用一个简短的、模型生成的标签替换终端标题；静态 `title` 是替换前的初值，也是兜底。
-- 该标签是模型概括，而非对提示词的截断。请求携带一段固定的任务指令（将该请求概括为两到五个小写单词、不含标点的简短标题）加上用户的首条消息，且不带工具；TUI 取回复的首个非空行并截断到 40 个字符（39 个字符加一个省略号）。
-- 标题通过 `runtime.terminal.setTitle` 设置——静态 `title` 已经在用的同一条 OSC 0 路径。不引入任何新的终端控制面，终端写入仍归 pi-tui 所有。
-- 该调用发出后不等待其返回，且每会话仅一次。一个 `titleSettled` 门闩守护它：`autoTitle` 关闭时它预先置为已结算、从不运行；在首条 `user/message` 已入日志的恢复会话中它预先结算，因此静态标题得以保留；仅含空白的首条消息被跳过且不消耗名额。任何失败、空回复、缺少 `llm` 服务、或缺少 agent 的 `provider` 或 `model`，都会让静态标题保持不动。一个专用的 `AbortController` 在关闭时取消尚在进行的请求。
-- 标题调用直接抵达 `ctx.llm.stream`，而非经由 `agent.send`，因此它从不追加进会话或 transcript（文本记录），也无法扰动 agent loop（智能体循环）。
-- 该功能默认关闭，仅在交互式产品配置（`examples/tui-agent/cordis.yml`）与脚本化 PTY fixture（测试前置数据）中开启。若在共享的 `dsh-tui-demo` schema 默认值里开启，会在不发送任何用户消息的无密钥回放与启动场景中多发一次模型调用。
-
-## Alternatives considered
-
-**截断首条用户消息，而非用模型生成标题。** 否决：用户选择的是简短的、模型制作的标签；截断后的原始提示词嘈杂、常以样板文字开头，且很少读起来像标题。
-
-**重命名窗口（OSC 2）或 tmux 窗口。** 否决：OSC 0 只设置 `pane_title`，因此它标记窗格而不重命名、也不泄漏进用户的窗口标题；用户确认 OSC 是正确的手段。
-
-**让该功能默认开启。** 否决：在共享的 demo schema 里开启会扰动无密钥回放与启动快照，并在每个全新会话上花掉一次模型调用；按部署选择性开启可让默认面保持惰性。
-
-**并入日志支撑的会话标题工作（PR #451）。** 否决：那项改动是持久化到日志的会话元数据；本项是不做持久化的终端标签。让二者相互独立可使各自自成一体，并避免共享依赖。
-
-**阻塞首轮直到标题就绪。** 否决：在发送用户消息前先等待标题，会给实际请求增加延迟；发出后不等待其返回可让重命名对该轮次不可见。
-
-## Consequences
-
-- 开启时，全新会话会多花一次无工具的模型调用，只带单条简短的用户消息和少量输出 token；默认关闭时它不产生任何开销。
-- 由于标题调用会打上 `sessionId`，它与会话的 `llm-replay` 游标共享：在以回放支撑的快照场景中开启 `autoTitle` 会消耗一条录制脚本条目。这正是它默认关闭、且脚本化 PTY fixture 用按工具分支的适配器而非回放来回答该调用的原因。
-- `packages/ui/tui/tests/tui.spec.ts` 用一个 mock `llm` 适配器固定该行为：生成的标题替换静态标题、过长输出以省略号截断、仅含空白的首条消息保留一次性名额、空回复或失败回复保留标题、恢复的会话从不触发，以及功能关闭 / 无服务 / 缺提供方 / 缺模型各路径都保留静态标题。一项关闭测试断言尚在进行的请求被中止。
-- `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` 证明真实的经 Loader 启动的路径：脚本化适配器以固定字符串回答无工具的标题调用，对话场景断言 OSC 0 序列抵达 PTY。启动场景不发送用户消息，因此它们从不触发该调用。

-# Agent Note: Auto-title on by default, re-derived on resume
-
-Status: implemented
-
-English | [中文](2026-07-21-tui-auto-title-default-on.zh.md)
-
-> **Superseded** by the [session-title consolidation Agent Note](../simplification/2026-07-22-tui-titles-from-session-title-service.md): the TUI-local `autoTitle` generation is removed; titles come from the log-backed session-title service, and the terminal rename consumes `session/title` events.
-
-## Problem
-
-The [auto-title Agent Note](2026-07-21-tui-auto-pane-title.md) shipped `autoTitle` off by default and, on a resumed session, kept the static title because the first `user/message` was already logged. In use both choices defeated the feature's purpose. A per-session descriptive pane title is what makes one tmux pane or terminal tab distinguishable from the next; leaving it off by default means the product ships an inert feature that almost no user turns on, and skipping re-derivation on resume means a resumed session — exactly the long-lived session most worth labelling — falls back to the shared static string. The user asked for a descriptive per-session name to be the normal experience.
-
-## Decision
-
-- `autoTitle` defaults **on** (`z.boolean().default(true)`, mirrored by `resolveTuiConfig`'s `?? true`). A deployment with an `llm` service and an agent provider/model gets a model-made pane title on every session without opting in; one without them keeps the static title, so default-on is inert where the call cannot run.
-- A **resumed** session re-derives the title on mount from its already-logged first `user/message`: `createTuiChat` scans `agent.session.events` for the first such event and feeds its text to the same one-shot `generateTitle`. The title is never persisted (the session header carries no title field), so it is always derived, never restored.
-- The one-shot latch is now simply `titleSettled = !resolved.autoTitle`. The prior pre-settle-on-resume clause is gone: on resume `generateTitle` runs once from the stored first message and then latches, so a message that arrives *after* the resume does not re-title. A fresh session has no stored `user/message` at mount, so the resume scan is a no-op and the live `session/event` listener titles the first message instead.
-- Everything else from the [auto-title Agent Note](2026-07-21-tui-auto-pane-title.md) stands unchanged: the OSC 0 `runtime.terminal.setTitle` path, the model-summary shape (two-to-five lowercase words, first non-empty line, 40-char cap), the fire-and-forget `ctx.llm.stream` call that never touches the session or transcript, the shutdown `AbortController`, and every failure fallback (empty reply, missing `llm`, missing provider/model, whitespace-only prompt).
-
-## Alternatives considered
-
-**Keep the feature off by default.** Rejected: this is a direct reversal of the [auto-title Agent Note](2026-07-21-tui-auto-pane-title.md)'s "default off" decision at the user's request. Off-by-default ships an inert feature; the descriptive name is only useful if it is the normal experience. The keyless-replay concern that motivated off-by-default is addressed by pinning `autoTitle: false` in the replay-backed snapshot scenarios rather than by suppressing it for every deployment.
-
-**Persist the derived title in the session header.** Rejected: the header has no title field and adding one would make a terminal label into session metadata — the boundary the [auto-title Agent Note](2026-07-21-tui-auto-pane-title.md) already drew against the log-backed session-title work. Re-deriving from the stored first message costs one tool-less call on resume and keeps the label a pure function of the conversation.
-
-**Re-derive on resume from the latest message instead of the first.** Rejected: the title summarises what the session is *about*, which its opening request captures; a mid-conversation message would make the pane label drift as the work moves on.
-
-## Consequences
-
-- A fresh session with a working `llm` now spends one extra tool-less model call by default (previously only when opted in); a resumed session spends one on mount. Deployments without an `llm` or provider/model are unaffected.
-- The replay-backed `examples/tui-agent/tests/tui.snapshot.ts` must opt **out**: it pins `autoTitle: false`, because a default-on title request is not among the recorded turns and `installLlmReplay` fails loud on an unrecorded request. The unit `packages/ui/tui/tests/tui.snapshot.ts` needs no opt-out — it mounts no `llm` service, so `generateTitle` short-circuits and the default flip is inert there. The interactive `examples/tui-agent/cordis.yml` and the scripted PTY fixture already set `autoTitle: true`, so the keyless smoke's OSC 0 assertion is unchanged.
-- `packages/ui/tui/tests/tui.spec.ts` pins the new defaults: the config-default test expects `autoTitle: true`; the disabled-path test now sets `autoTitle: false` explicitly; and the former "resumed session never fires" test is rewritten to assert re-derivation from the stored first message and that a later live message does not re-title. `docs/config-catalog.md` regenerates to "On by default".

-# Agent Note: 自动标题默认开启，恢复时重新推导

-
-[English](2026-07-21-tui-auto-title-default-on.md) | 中文

-> **已被取代**：见[标题归一 Agent Note](../simplification/2026-07-22-tui-titles-from-session-title-service.md)。TUI 本地的 `autoTitle` 生成已移除；标题来自日志承载的 session-title 服务，终端重命名消费 `session/title` 事件。
-
-## Problem
-
-[自动标题 Agent Note](2026-07-21-tui-auto-pane-title.md) 交付时 `autoTitle` 默认关闭，并且在恢复会话中因首条 `user/message` 已入日志而保留静态标题。实际使用中这两个选择都违背了该功能的初衷。让一个 tmux 窗格或终端标签页区别于下一个的，正是每会话各异的描述性窗格标题；默认关闭意味着产品交付了一个几乎无人开启的惰性功能，而恢复时不重新推导，则意味着恢复会话——恰恰是最值得标记的长命会话——退回到共用的静态字符串。用户要求把每会话的描述性名称做成常态体验。
-
-## Decision
-
-- `autoTitle` 默认**开启**（`z.boolean().default(true)`，`resolveTuiConfig` 以 `?? true` 与之对齐）。带有 `llm` 服务与 agent 提供方/模型的部署无需选择性开启即可在每个会话获得模型制作的窗格标题；不具备它们的部署保留静态标题，因此在调用无法运行处，默认开启是惰性的。
-- **恢复**会话在挂载时从其已入日志的首条 `user/message` 重新推导标题：`createTuiChat` 在 `agent.session.events` 中扫描首个此类事件，并把其文本喂给同一个一次性的 `generateTitle`。标题从不持久化（会话头不携带标题字段），因此它始终是推导得来，而非恢复而来。
-- 一次性门闩现在只是 `titleSettled = !resolved.autoTitle`。此前"恢复即预先结算"的分句已删除：恢复时 `generateTitle` 从已存储的首条消息运行一次随后上闩，因此恢复*之后*到达的消息不会再改标题。全新会话在挂载时没有已存储的 `user/message`，因此恢复扫描是空操作，改由实时的 `session/event` 监听器为首条消息命名。
-- [自动标题 Agent Note](2026-07-21-tui-auto-pane-title.md) 的其余一切保持不变：OSC 0 的 `runtime.terminal.setTitle` 路径、模型概括形态（两到五个小写单词、首个非空行、40 字符上限）、从不触碰会话或 transcript（文本记录）的发出后不等待其返回的 `ctx.llm.stream` 调用、关闭时的 `AbortController`，以及每一条失败兜底（空回复、缺 `llm`、缺提供方/模型、仅含空白的提示词）。
-
-## Alternatives considered
-
-**让该功能保持默认关闭。** 否决：这是应用户要求，对[自动标题 Agent Note](2026-07-21-tui-auto-pane-title.md)"默认关闭"决策的直接反转。默认关闭交付的是惰性功能；只有当描述性名称成为常态体验时它才有用。当初促成默认关闭的无密钥回放顾虑，改由在以回放支撑的快照场景中固定 `autoTitle: false` 来处理，而非为每个部署都压制该功能。
-
-**把推导出的标题持久化进会话头。** 否决：会话头没有标题字段，加一个会把终端标签变成会话元数据——正是[自动标题 Agent Note](2026-07-21-tui-auto-pane-title.md)已经对日志支撑的会话标题工作划出的边界。从已存储的首条消息重新推导，代价是恢复时一次无工具调用，并让标签保持为对话的纯函数。
-
-**恢复时从最新消息而非首条消息重新推导。** 否决：标题概括的是会话*关于什么*，而这由其开场请求捕获；一条对话中途的消息会让窗格标签随工作推进而漂移。
-
-## Consequences
-
-- 带可用 `llm` 的全新会话现在默认多花一次无工具的模型调用（此前只在选择性开启时才有）；恢复会话在挂载时花掉一次。不具备 `llm` 或提供方/模型的部署不受影响。
-- 以回放支撑的 `examples/tui-agent/tests/tui.snapshot.ts` 必须选择**关闭**：它固定 `autoTitle: false`，因为默认开启的标题请求不在录制轮次之列，而 `installLlmReplay` 对未录制的请求会显式报错。单元 `packages/ui/tui/tests/tui.snapshot.ts` 无需选择关闭——它不挂载 `llm` 服务，因此 `generateTitle` 提前短路，默认值的翻转在那里是惰性的。交互式的 `examples/tui-agent/cordis.yml` 与脚本化 PTY fixture（测试前置数据）已设 `autoTitle: true`，因此无密钥冒烟测试的 OSC 0 断言保持不变。
-- `packages/ui/tui/tests/tui.spec.ts` 固定新的默认值：config 默认测试期望 `autoTitle: true`；关闭路径测试现在显式设 `autoTitle: false`；此前的"恢复会话从不触发"测试改写为断言从已存储首条消息重新推导，并断言之后的实时消息不会再改标题。`docs/config-catalog.md` 重新生成为"On by default"。

-# Agent Note: The banner sweeps in; the subtitle line is gone
-
-Status: implemented
-
-English | [中文](2026-07-21-tui-banner-sweep.zh.md)
-
-> **Superseded** by the [no-banner Agent Note](2026-07-21-tui-no-banner.md): the banner itself was removed, taking the sweep with it.
-
-## Problem
-
-The [startup-slogans Agent Note](2026-07-20-tui-startup-slogans.md) replaced the instructional welcome line with a random slogan bank revealed by a per-character typewriter. In use the quotes read as weird — random flavor text in a tool's header — and the animation was slow (40 ms/char over a full sentence) while animating only one line of a four-line banner. This note supersedes that decision's slogan half; the removal of the configured demo welcome and the animation-lifecycle groundwork stand.
-
-## Decision
-
-- The slogan bank, `pickStartupSlogan`, and the typewriter reveal are deleted. When `welcome` is unset the banner simply has **no subtitle line** — title and model/session detail only. The `welcome` config remains for deployments and fixtures that want a fixed subtitle, rendered frame-deterministically with no animation.
-- The startup animation is now the **whole banner**: `HeaderComponent` gains a `revealWidth` clip, and the header box wipes in left-to-right over ~24 frames at 15 ms (~360 ms total, ~60 fps), started after `ui.start()` succeeds and cleared through the same `detachListeners` path the typewriter used. `stopBannerReveal` also resets the clip so a disposed-mid-sweep header re-renders whole.
-- The PTY smoke's boot marker changes from the typewriter cursor (`▌`) to the banner's top-right corner (`╮`), which only renders once the sweep completes.
-
-## Alternatives considered
-
-**Keep the animation as-is and only change the copy.** Rejected: any fixed or rotating phrase re-read on every boot decays into wallpaper; the user's judgment was that the quotes themselves, not just their content, were wrong for the surface.
-
-**Animate per banner line (top-down) instead of a left-right sweep.** Rejected: with only four lines the animation would have four visible steps — closer to a flicker than a reveal; the horizontal sweep uses the full terminal width for a smooth motion at the same total duration.
-
-**Character-level clipping via `revealWidth` on styled text.** Adopted with `truncateToWidth` from pi-tui, the same ANSI-aware clipper the header already uses for width overflow, so the sweep cannot tear escape sequences.
-
-## Consequences
-
-- Boot output with `welcome` unset is again animation-dependent but no longer random: every boot sweeps the same banner. Configured welcomes (all snapshot/scripted fixtures, the Code Mode overlay) stay frame-deterministic and unchanged.
-- The `STARTUP_SLOGANS`/`pickStartupSlogan` exports are gone; no consumer outside the deleted tests referenced them.
-- The default banner is one line shorter (no subtitle), so PTY assertions anchored on banner geometry use the corner glyph rather than any subtitle text.
-
-## Testing
-
-`packages/ui/tui/tests/tui.spec.ts` pins: the sweep completes to a full banner (both corners + title) and produced at least one clipped mid-sweep frame; a configured welcome renders verbatim with no clipped frames; the unset-welcome banner has no subtitle; and dispose clears the sweep's own interval handle. The PTY smoke boots on the `╮` completion marker across the tui-demo bin, the dsh CLI, and the personal-overlay scenarios. Verified live in tmux.

-# Agent Note: 横幅整体扫入；副标题行移除
-
-Status: implemented
-
-[English](2026-07-21-tui-banner-sweep.md) | 中文
-
-> **已被取代**：由[移除启动横幅 Agent Note](2026-07-21-tui-no-banner.md)取代：横幅本身已移除，扫入动画随之移除。
-
-## Problem
-
-[启动 slogan Agent Note](2026-07-20-tui-startup-slogans.md) 用随机 slogan 库加逐字打字机动画取代了说明书式的欢迎行。实际使用中这些引语显得怪异——工具头部出现随机的风味文案——而且动画很慢（每字符 40 ms，扫完一整句），却只动画四行横幅中的一行。本 note 取代该决定中 slogan 的那一半；移除示例配置中欢迎语的决定与动画生命周期的基础设施保持不变。
-
-## Decision
-
-- 删除 slogan 库、`pickStartupSlogan` 和打字机动画。`welcome` 未设置时横幅直接**没有副标题行**——只有标题和模型/会话详情。`welcome` 配置保留给想要固定副标题的部署与 fixture，无动画、逐帧确定地渲染。
-- 启动动画现在作用于**整个横幅**：`HeaderComponent` 增加 `revealWidth` 裁剪，头部盒子以约 24 帧、每帧 15 ms（总计约 360 ms、约 60 fps）从左到右扫入，在 `ui.start()` 成功后启动，经打字机动画用过的同一条 `detachListeners` 路径清除。`stopBannerReveal` 同时重置裁剪，因此扫入中途被 dispose 的头部会重新完整渲染。
-- PTY 冒烟测试的启动标记从打字机光标（`▌`）改为横幅右上角（`╮`），它只在扫入完成后才渲染。
-
-## Alternatives considered
-
-**保留动画原样、只改文案。** 否决：任何每次启动都被重读的固定或轮换语句都会退化成墙纸；用户的判断是引语本身——而不只是内容——对这个表面来说就是错的。
-
-**按横幅行逐行（自上而下）动画而非左右扫入。** 否决：只有四行时动画只有四个可见步骤——更像闪烁而不是展开；水平扫入用满终端宽度，在相同总时长内动作更平滑。
-
-**用 `revealWidth` 对带样式文本做字符级裁剪。** 采用 pi-tui 的 `truncateToWidth`——头部处理宽度溢出时已在使用的同一个 ANSI 感知裁剪器——因此扫入不可能撕裂转义序列。
-
-## Consequences
-
-- `welcome` 未设置时启动输出再次依赖动画但不再随机：每次启动扫入同一幅横幅。配置了欢迎语的场景（全部快照/脚本化 fixture、Code Mode overlay）保持逐帧确定且不变。
-- `STARTUP_SLOGANS`/`pickStartupSlogan` 导出移除；除被删除的测试外没有消费者引用它们。
-- 默认横幅少一行（无副标题），因此锚定横幅几何的 PTY 断言使用角落字形而非任何副标题文本。
-
-## Testing
-
-`packages/ui/tui/tests/tui.spec.ts` 固定：扫入完成为完整横幅（两个角 + 标题）且产生了至少一个裁剪的中途帧；配置的欢迎语原文渲染且无裁剪帧；未设置欢迎语的横幅没有副标题；dispose 清除扫入自己的定时器句柄。PTY 冒烟测试在 tui-demo bin、dsh CLI 和个人 overlay 场景中以 `╮` 完成标记启动。已在 tmux 中实机验证。

## Problem
-The [no-banner Agent Note](2026-07-21-tui-no-banner.md) removed the boxed startup banner: it deleted `HeaderComponent` and its sweep, moved the model into the footer, dropped the session id, and rendered `welcome` as the transcript's first line. The user's verdict reversed that: bring the banner back — "just remove the border". The four-row box frame was the objectionable chrome, not the identifying facts it carried (model, session id) nor the sweep-in motion.
+An intermediate no-banner design removed the boxed startup banner: it deleted `HeaderComponent` and its sweep, moved the model into the footer, dropped the session id, and rendered `welcome` as the transcript's first line. The user's verdict reversed that: bring the banner back — "just remove the border". The four-row box frame was the objectionable chrome, not the identifying facts it carried (model, session id) nor the sweep-in motion.
## Decision
-- `HeaderComponent` and its left-to-right sweep return, but render **borderless**: no `╭─╮`/`╰─╯` corners and no `│` side bars. Each line is a single leading space plus `truncateToWidth`-clipped content, so the sweep's width clip can never tear an escape sequence and no fixed frame is drawn.
-- The header carries the title (`DEEPSEEK HARNESS`), a `<model> • <session-id>` detail line, and — when `welcome` is set — a muted subtitle. With `welcome` unset the header is title + detail only.
-- The model **also** stays in the footer's left segment. The no-banner note's footer model prefix is kept, not reverted, so the driving model stays glanceable after the transient banner scrolls out of view.
+- `HeaderComponent` and its left-to-right sweep return, but render **borderless**: no `╭─╮`/`╰─╯` corners and no `│` side bars. Each line is a single leading space plus `truncateToWidth`-clipped content, so the sweep's width clip can never tear an escape sequence and no fixed frame is drawn. The reveal advances through about 24 frames at 15 ms each.
+- The header carries the title (`DEEPSEEK HARNESS`), a `<model> • <session-id>` detail line, and — when `welcome` is set — a muted subtitle. With `welcome` unset the header is title + detail only: there is no fixed or random slogan.
+- The model **also** stays in the footer's left segment, so the driving model remains glanceable after the transient banner scrolls out of view.
- `welcome` reverts to a banner subtitle; the transcript-first-line notice is removed from `rebuildTranscript`.
- The sweep animates only when `welcome` is unset. A configured `welcome` renders the whole banner immediately, keeping fixtures and snapshots frame-deterministic. The sweep starts after `ui.start()` succeeds and is cleared through the same `detachListeners` path via `stopBannerReveal`, which also resets the clip so a header disposed mid-sweep re-renders whole.
-This supersedes the [no-banner Agent Note](2026-07-21-tui-no-banner.md) (which superseded the [banner-sweep Agent Note](2026-07-21-tui-banner-sweep.md)): the banner and its sweep return borderless, while the model's footer home the no-banner note added stays.
+This note owns the current result of the discarded startup variants: random slogans with a per-character typewriter, a boxed whole-banner sweep, and no banner. The example composition does not set `welcome`; deployments and deterministic fixtures may still provide one. The model's persistent footer home from the no-banner variant remains.
## Alternatives considered
**Keep the box but thin it or use lighter glyphs.** Rejected: the instruction was "just remove the border"; any surrounding glyph is the frame chrome the user objected to.
-**Drop the model from the footer now that the banner shows it again.** Rejected: the banner is transient and scrolls away with the transcript, while the footer keeps the model visible for the whole session — the reason the no-banner note put it there, deliberately preserved.
+**Keep a random or fixed slogan when `welcome` is unset.** Rejected because repeated flavor copy becomes wallpaper and the per-character reveal was slow while animating only one line. An unset welcome therefore produces no subtitle, and the whole banner supplies the startup motion.
-**Leave the session id out, as the no-banner note decided.** Rejected: with the box gone the detail line costs one row, and the user asked for the banner "as before", which carried `model • session-id`.
+**Remove the banner entirely.** Rejected because the persistent footer is a good home for the model but not for the full identifying detail, while putting `welcome` in the transcript makes presentation configuration behave like conversation content.
+
+**Reveal the banner top-down.** Rejected because four row-sized steps read as a flicker. The horizontal width clip uses the terminal span for smooth motion and reuses the ANSI-aware truncation path.
+
+**Drop the model from the footer now that the banner shows it again.** Rejected: the banner is transient and scrolls away with the transcript, while the footer keeps the model visible for the whole session; that persistent location is deliberately preserved.
+
+**Leave the session id out of the banner.** Rejected: with the box gone the detail line costs one row, and the user asked for the banner "as before", which carried `model • session-id`.
## Consequences
- Boot output with `welcome` unset is animation-dependent again (the sweep); configured welcomes stay frame-deterministic, so every snapshot and scripted fixture keeps a fixed subtitle.
+- The demo no longer supplies instructional welcome filler; an unset `welcome` means a subtitle-free banner, while the config remains the deterministic escape hatch for deployments and fixtures.
- The model now appears twice at boot — banner detail and footer — intended redundancy: the banner is transient, the footer persistent.
-- `/clear` empties the transcript but not the header, so the banner and its configured subtitle survive `/clear`, unlike the no-banner welcome line that `/clear` wiped.
+- `/clear` empties the transcript but not the header, so the banner and its configured subtitle survive `/clear`, unlike a transcript-based welcome line.
- All pi-tui terminal snapshots and the examples/tui-agent replay snapshots re-recorded (`test:snapshot:refresh`): banner rows return with no box glyphs; footer rows keep the model prefix.
- Anything that anchored on banner absence re-anchors on its presence: the PTY smoke boots on the detail line's `main-session-` id (revealed late in the sweep) and asserts `DEEPSEEK`/`HARNESS` present with no box corners.
## Testing
-`packages/ui/tui/tests/tui.spec.ts` pins: the borderless banner sweeps to natural completion — no box corners, title and `main-session` detail present — with at least one clipped mid-sweep frame; a configured `welcome` renders the whole banner with no clipped frame; the unset-welcome banner has no subtitle; and dispose clears the sweep interval mid-sweep. The tui-agent and dsh-CLI PTY smokes boot on the `main-session-` detail marker and assert no box corners. Snapshots verify the full frames.

## Problem
-[移除横幅 Agent Note](2026-07-21-tui-no-banner.md) 删掉了带框的启动横幅：它删除了 `HeaderComponent` 及其扫入动画，把模型移入页脚，丢弃了会话 id，并把 `welcome` 渲染为 transcript 的第一行。用户的裁决把这一切反转：把横幅拿回来——"just remove the border"。令人反感的装饰是那四行盒子边框，而不是它承载的识别信息（模型、会话 id），也不是扫入动效。
+一个中间的无横幅设计删掉了带框的启动横幅：它删除了 `HeaderComponent` 及其扫入动画，把模型移入页脚，丢弃了会话 id，并把 `welcome` 渲染为 transcript 的第一行。用户的裁决把这一切反转：把横幅拿回来——"just remove the border"。令人反感的装饰是那四行盒子边框，而不是它承载的识别信息（模型、会话 id），也不是扫入动效。
## Decision
-- `HeaderComponent` 及其从左到右的扫入动画回归，但以**无边框**方式渲染：没有 `╭─╮`/`╰─╯` 边角，也没有 `│` 侧边。每一行都是一个前导空格加上经 `truncateToWidth` 裁剪的内容，因此扫入的宽度裁剪永远不会撕裂转义序列，也不绘制任何固定边框。

- `welcome` 恢复为横幅副标题；transcript 第一行的通知从 `rebuildTranscript` 中移除。
- 仅当 `welcome` 未设置时才播放扫入动画。配置了 `welcome` 会立即渲染整个横幅，使 fixture 和快照保持帧确定性。扫入在 `ui.start()` 成功后启动，并经与之前相同的 `detachListeners` 路径通过 `stopBannerReveal` 清理；后者还会重置裁剪，使扫入中途被销毁的头部重新完整渲染。
-本 note 取代[移除横幅 Agent Note](2026-07-21-tui-no-banner.md)（后者取代了[横幅扫入 Agent Note](2026-07-21-tui-banner-sweep.md)）：横幅及其扫入动画以无边框方式回归，而移除横幅那版 note 为模型设立的页脚归宿得以保留。

+**在未设置 `welcome` 时保留随机或固定标语。** 否决：反复出现的氛围文案很快失去信息价值，而逐字揭示仅为一行制作动画，速度又慢。因此，未设置 `welcome` 时不显示副标题，由整个横幅提供启动动效。
-**像移除横幅那版 note 那样，把会话 id 留在外面。** 否决：盒子去掉后详情行只占一行，且用户要求横幅"和以前一样"，而以前它承载 `model • session-id`。
+**完全移除横幅。** 否决：常驻页脚很适合显示模型，却无法承载完整识别详情；把 `welcome` 放入 transcript 还会使展示配置表现成对话内容。
+
+**自上而下揭示横幅。** 否决：按四行分成四步看起来像闪烁。横向宽度裁剪利用终端横向空间实现平滑动效，并复用 ANSI 感知的截断路径。

-# Agent Note: No startup banner

-Status: implemented
-
-English | [中文](2026-07-21-tui-no-banner.zh.md)
-
-> **Superseded** by the [borderless-banner Agent Note](2026-07-21-tui-borderless-banner.md): the banner and its sweep return without the box. The model's footer home this note added stays.
-
-## Problem
-
-The TUI opened with a boxed product banner ("DEEPSEEK HARNESS" + model/session detail), most recently with a sweep-in animation ([banner sweep Agent Note](2026-07-21-tui-banner-sweep.md)). The user's verdict: remove it. A product title re-read on every boot is chrome, the box spends four rows before any content, and the identifying facts it carried (model, session) have better homes.
-
-## Decision
-
-- `HeaderComponent`, the sweep animation, and its lifecycle wiring are deleted. The TUI mounts straight into the transcript; startup renders nothing above the separator.
-- The model name moves into the footer status line's left segment (`<model> <cwd> ↑tokens ↓tokens`), so the session's driving model stays visible at all times, not just at boot. The session id is no longer displayed — it lives in the session log and `./.sessions` filenames, and `RESUME_SESSION_ID` consumers retrieve it there.
-- `welcome`, when configured, renders as the transcript's first line (a muted notice) inside `rebuildTranscript`, so palette swaps preserve it. Unset renders nothing. Fixtures keep their configured welcomes; the PTY smoke's boot marker becomes the footer's model name, the only mounted-TUI text guaranteed to render regardless of cwd length.
-
-This supersedes the [banner sweep Agent Note](2026-07-21-tui-banner-sweep.md) entirely: both the sweep and the banner it animated are gone.
-
-## Alternatives considered
-
-**Keep a one-line header (no box).** Rejected: the only load-bearing fact was the model name, and the footer already aggregates session status; a dedicated header row for one fact is the same chrome, smaller.
-
-**Show the session id in the footer too.** Rejected: a 36-char UUID dominates the 100-column footer and clips the status segment; it identifies the session for resume, which is a log/filesystem concern, not a glanceable one.
-
-**Print the welcome outside the transcript (above the separator).** Rejected: any fixed region above the transcript is a banner again; as a transcript line it scrolls away naturally and survives rebuilds through the same path as every other transcript element.
-
-## Consequences
-
-- Startup output is fully deterministic again — no animation frames at all; the interval-lifecycle machinery from the two animation iterations is gone.
-- All 26 pi-tui terminal snapshots re-recorded (`test:snapshot:refresh`): banner rows gone, footer rows gain the model prefix.
-- Anything that anchored on banner text (`DEEPSEEK`, box corners) re-anchors on the footer model name; `main-session-` no longer appears in boot output.
-- `/clear` now wipes the welcome line too: it is an ordinary transcript line, and `/clear` empties the transcript (the old banner survived `/clear` only by sitting outside it).
-- The footer's left segment is wider; on narrow terminals the right status segment clips earlier.
-
-## Testing
-
-`packages/ui/tui/tests/tui.spec.ts` pins: no box corners/product title and an empty transcript when `welcome` is unset, with the model in the footer; a configured welcome as the first transcript line without a banner; and the welcome surviving a palette-swap transcript rebuild. The PTY smoke boots on the footer model name and asserts `DEEPSEEK HARNESS` is absent. Snapshots verify the full frames.

-> **已被取代**，见[无边框横幅 Agent Note](2026-07-21-tui-borderless-banner.md)：横幅及其扫入动画回归，只是去掉了盒子。本 note 为模型设立的页脚归宿得以保留。
-
-## Problem
-
-TUI 启动时展示一个带框的产品横幅（"DEEPSEEK HARNESS" + 模型/会话详情），最近一版还带扫入动画（[横幅扫入 Agent Note](2026-07-21-tui-banner-sweep.md)）。用户的裁决：删掉它。每次启动都被重读的产品标题是装饰，盒子在任何内容之前先占掉四行，而它承载的识别信息（模型、会话）有更好的去处。
-
-## Decision
-
-- 删除 `HeaderComponent`、扫入动画及其生命周期接线。TUI 直接挂载进 transcript；启动时分隔线之上不渲染任何东西。
-- 模型名移入页脚状态行的左段（`<model> <cwd> ↑tokens ↓tokens`），会话使用的模型因此始终可见，而不只是启动时。会话 id 不再显示——它存在于会话日志和 `./.sessions` 文件名中，`RESUME_SESSION_ID` 的使用者从那里获取。
-- 配置了 `welcome` 时，它作为 transcript 的第一行（一条弱化的通知）在 `rebuildTranscript` 内渲染，因此调色板切换会保留它。未设置则什么也不渲染。fixture 保留各自配置的欢迎语；PTY 冒烟测试的启动标记改为页脚的模型名——无论 cwd 多长都保证渲染的唯一挂载后文本。
-
-本 note 完全取代[横幅扫入 Agent Note](2026-07-21-tui-banner-sweep.md)：扫入动画和它所动画的横幅都已移除。
-
-## Alternatives considered
-
-**保留单行头部（去掉盒子）。** 否决：唯一有承载价值的信息是模型名，而页脚已经聚合会话状态；为一条信息保留专用头部行仍是同一种装饰，只是小一点。
-
-**把会话 id 也放进页脚。** 否决：36 字符的 UUID 会占满 100 列页脚并裁掉状态段；它的用途是恢复会话的标识，属于日志/文件系统关注点，不是需要一瞥可见的信息。
-
-**把欢迎语渲染在 transcript 之外（分隔线上方）。** 否决：transcript 上方任何固定区域都会再次变成横幅；作为 transcript 行它自然滚走，并通过与其他 transcript 元素相同的路径在重建后保留。
-
-## Consequences
-
-- 启动输出再次完全确定——没有任何动画帧；两轮动画迭代留下的定时器生命周期机制全部移除。
-- 全部 26 个 pi-tui 终端快照重新录制（`test:snapshot:refresh`）：横幅行消失，页脚行增加模型前缀。
-- 锚定横幅文本（`DEEPSEEK`、盒子角）的内容改为锚定页脚模型名；启动输出中不再出现 `main-session-`。
-- `/clear` 现在也会清掉欢迎行：它是普通的 transcript 行，而 `/clear` 清空 transcript（旧横幅能在 `/clear` 后存活只因为它在 transcript 之外）。
-- 页脚左段变宽；窄终端上右侧状态段更早被裁剪。

## Problem
-The TUI can resume a session by launch (`RESUME_SESSION_ID=<id> dsh` feeding `dsh-tui-demo`'s `resumeSessionId`), but nothing told the user the command. On exit the session id survived only in the log and `./.sessions` filenames — the [no-banner Agent Note](2026-07-21-tui-no-banner.md) removed the last place it was shown — so resuming meant hunting for the id and reconstructing the invocation. There was also no in-session way to see which sessions in this workspace are resumable.
+The original `/resume` printed shell commands. It did not let a keyboard user inspect titles or outcomes, distinguish corruption from a missing adapter, or safely transfer the terminal. Leaving the TUI and manually launching a command also hid the required ordering: finish current work, flush it, release the UI and app, then restore the exact persisted identity without silently creating a replacement.
## Decision
-A single optional `resumeCommand` config field on `dsh-tui` gates both surfaces: a shell command template whose every `{session}` is replaced with the live session id (e.g. `dsh --resume {session}`). Absent, neither surface appears.
+`/resume` uses the TUI's existing interactive overlay seam as a full-viewport picker rather than a centered dialog. The flat page keeps the search field, workspace, candidates, and shortcut footer in stable screen regions; only the active row uses the accent role. Its search editor starts immediately after the search glyph and emits pi-tui's cursor marker, so terminal IME composition remains anchored in the field. Escape clears a non-empty query before a second Escape closes the picker. It lists the current workspace by last logged activity and searches log-backed title or id. Each candidate displays current/live/persisted state, last turn outcome, recent provider/model, durable goal phase when present, and the id as secondary text. The current session and sessions already live in this runtime remain visible but disabled.
-- **Exit hint.** Process-exiting shutdown prints `To resume this session: <command>` (muted label) via `runtime.terminal.write` after `ui.stop()`, before `runtime.exit`. It prints only once the session is durably persisted: `currentResumeCommand()` scans the session list for the current id and returns `undefined` if it is absent, so a session abandoned before its first flush advertises no command that would fail to load.
-- **`/resume`.** Lists this workspace's persisted sessions newest-first, each with its resume command, marking the current one `(current)`. It warns when `resumeCommand` is unconfigured or no persistence backend is mounted, and notes when nothing is persisted yet. The listing is asynchronous, so the transcript updates a tick after submit.
-- **Listing.** `listWorkspaceSessions()` reads the optional `sessionPersistence` service's `list()`, keeps headers whose `cwd === agent.session.header.cwd`, and sorts by `createdAt` descending. A `list()` rejection is swallowed to `[]` — a persistence failure must never block terminal exit or crash `/resume`.
+`session-query.readSession()` supplies a detached complete log validated by the same core replay boundary used by resume. The TUI folds title and goal state from that log. A candidate load failure is local to that row; selecting a candidate revalidates the log, `cwd`, route, current agent's idle status, and the exclusions for the current session and sessions already live in this runtime, so a stale listing cannot bypass preflight. A missing adapter reports an intact session with an unavailable route. This preflight does not lock the target or exclude another process.
-`sessionPersistence` is an optional injected service reached through `ctx.get('sessionPersistence')` (not `inject`), declared as an optional peer dependency. Without a backend the field still parses; the exit hint and `/resume` degrade to nothing and the unconfigured/no-backend warnings respectively. `dsh-tui-demo` forwards `resumeCommand` to `dsh-tui`, and the runnable `examples/tui-agent` leaves set `dsh --resume {session}`. The `dsh` CLI (`apps/cli`) parses that `--resume <id>` flag through `parseResumeArg` in [`dsh-app-boot`](../../../../packages/ui/app-boot/README.md), setting `RESUME_SESSION_ID` before boot so the printed command runs back through the config's existing `resumeSessionId` intake; a mistyped or repeated flag fails loud rather than silently starting fresh.
+After preflight, the TUI flushes the current session, confirms that its agent remains idle, then stops the terminal before calling `TuiRuntime.handoffResume`. The shipped `dsh` host disposes the root app and uses `process.execve` with a normalized `--resume` argument, atomically replacing the process rather than starting a child. The resumed app publishes the same `SessionId`; ordinary replay restores transcript, title, todos, and durable goal state. Goal activation is intentionally disarmed, and the TUI asks for human confirmation or `/goal resume`.
+
+`resumeCommand` remains an exit and no-host fallback. The TUI substitutes `{session}` only for display and never executes arbitrary shell text. The exit hint still appears only after the current session is durable.
## Alternatives considered
-**Hardcode or auto-detect the resume invocation.** Rejected: the launch command is deployment-specific — the env-var name, binary, and flags all vary — so a `DEFAULT_*` constant would be a fixed tunable, not configurability. A template owned by the leaf keeps the choice where the deployment lives, and `{session}` is the only substitution the TUI must know.
+**Have the TUI spawn `resumeCommand`.** Rejected: the template is deployment text, not trusted argv, and the TUI does not own app teardown or process lifetime. The constrained host seam receives only a validated `SessionId`.
-**Two config fields, one per surface.** Rejected: both render the identical command, so one field keeps them symmetric and unable to drift; there is no deployment that wants the hint but not the listing.
+**Construct the resumed agent inside the existing TUI.** Rejected: replacing one config-created agent would cross Loader ownership, scoped plugin setup, persistence retirement, and terminal lifecycle in the presentation layer. Root disposal plus process replacement reuses the supported startup path.
-**Print the exit hint unconditionally.** Rejected: resuming a session id that never flushed fails to load, so advertising it is a broken instruction. Gating on the id appearing in `list()` costs one scan and only ever suppresses a dead command.
+**Treat a missing adapter as a missing session.** Rejected: storage validity and current route availability are independent facts. The selector keeps the row and names the unavailable provider/model.
-**Resume in place from `/resume` (relaunch or reattach).** Rejected: the TUI does not own agent lifecycle or process spawning ([front-door Agent Note](2026-07-17-dedicated-full-screen-tui-front-door.md)). Printing a copyable command respects that boundary and matches the `pi --resume` affordance the request cited.
-
-**Make `sessionPersistence` a required `inject`.** Rejected: the TUI must run without persistence (fixtures, ephemeral runs). An optional service that degrades preserves that, and matches the [`session-query`](../../../../packages/session-query/session-query/package.json) precedent for the same optional peer.
+**Persist goal activation across resume.** Rejected: durable intent is not authorization to continue after a human or process boundary. Goal phase survives; automatic continuation does not.
## Consequences
-- `dsh-tui` gains an optional peer dependency on `@deepseek-ai/dsh-session-persistence` (`peerDependenciesMeta.optional`), matching `session-query`; the package still loads and passes its coverage gate without a backend mounted.
-- The help line and autocomplete gain `/resume`; two existing snapshots re-recorded for the wider help line, and a new `resume-sessions` checkpoint pins the rendered listing.
-- `dsh-tui-demo` and both `examples/tui-agent` leaves carry `resumeCommand`, so a real TUI run now prints its own resume command on exit, and the `dsh` CLI accepts the printed `--resume <id>` flag to run it.
+- Concurrent processes can select or resume the same persisted session because preflight does not serialize them.
+- `/resume` depends on `session-query` for discovery and complete-log reads, but persistence and host handoff remain optional; without a host, the command fallback stays usable.
+- Process replacement intentionally restarts Loader composition. Runtime-only state is rebuilt, while only logged or header-backed session state survives.
## Testing
-`packages/ui/tui/tests/tui.spec.ts` pins the seven behaviors: the exit hint prints only when the current session is persisted, is omitted when it is not and when `list()` rejects; `/resume` lists workspace sessions newest-first with the `(current)` marker and cwd filter, warns when unconfigured and when no backend is mounted, and notes when nothing is persisted. The `resume-sessions` snapshot verifies the full rendered frame. The harness provides a fake `sessionPersistence` through `ctx.provide`. For the `--resume` flag, `packages/ui/app-boot/tests/app-boot.spec.ts` pins `parseResumeArg` (space and inline forms, position independence, and the fail-loud on a valueless, empty, or repeated flag), and `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` boots `apps/cli` with `--resume <missing-id>` and asserts the config resume fails loud — proving the flag reaches the `resumeSessionId` intake.
+TUI tests cover keyboard navigation, title/id search, search-clear/cancel behavior, running-agent refusal, refusal of the current session and sessions already live in this runtime, route absence, corrupt rows, preflight revalidation, fallback commands, and stop-before-handoff ordering. Session-query tests pin detached full-log validation. Agent-loop resume tests pin exact identity and history; title, todo, and goal replay suites pin restored projections and disarmed goal activation. The keyless TUI snapshot owns the full-viewport selector and its IME cursor anchor, and a real PTY smoke covers search plus handoff.

## Problem
-TUI 本就能通过启动参数恢复会话（`RESUME_SESSION_ID=<id> dsh` 喂给 `dsh-tui-demo` 的 `resumeSessionId`），但没有任何地方告诉用户这条命令。退出时会话 id 只残留在会话日志和 `./.sessions` 文件名里——[移除启动横幅 Agent Note](2026-07-21-tui-no-banner.md) 移除了它最后一处显示位置——因此恢复意味着先翻出 id 再拼回调用命令。也没有任何会话内的方式查看当前 workspace 里哪些会话可恢复。
+原有 `/resume` 只会打印 shell 命令。使用键盘操作的用户无法查看标题或结果、区分日志损坏与适配器缺失，也无法安全移交终端。退出 TUI 后手动启动命令还掩盖了必要的操作顺序：等待当前工作结束并将其刷写，释放 UI 和应用，再恢复持久化的原有身份，绝不能静默创建替代会话。
## Decision
-`dsh-tui` 上一个可选的 `resumeCommand` 配置字段同时管辖两处出口：一个 shell 命令模板，其中每一处 `{session}` 都会被替换为当前会话 id（例如 `dsh --resume {session}`）。未设置时两处都不出现。
+`/resume` 使用 TUI 现有的交互式浮层接口，但以占满 viewport 的选择页呈现，而不是居中弹窗。这个扁平页面把搜索框、workspace、候选项和快捷键页脚放在稳定的屏幕区域，只有当前行使用强调色。搜索编辑器紧跟搜索图标起始，并输出 pi-tui 的光标标记，因此终端输入法的组合文本会锚定在输入框中。查询非空时，第一次按 Escape 会清空查询，第二次才关闭选择页。页面按日志记录的最后活动时间列出当前 workspace 的会话，并支持按日志内标题或 id 搜索。每个候选项都会显示是否为当前会话、是否活跃、是否已持久化，最近一个轮次的结果，最近使用的提供方／模型，以及可用时的持久化目标阶段；id 作为次要信息显示。当前会话和已在本运行时中处于活跃状态的会话仍会显示，但不可选择。
-- **退出提示。** 以退出进程方式关闭时，在 `ui.stop()` 之后、`runtime.exit` 之前，经由 `runtime.terminal.write` 打印 `To resume this session: <command>`（弱化的标签）。仅当会话已持久化时才打印：`currentResumeCommand()` 在会话列表中查找当前 id，若不存在则返回 `undefined`，因此在首次刷盘前就被放弃的会话不会宣传一条注定加载失败的命令。
-- **`/resume`。** 按最新在前列出当前 workspace 里已持久化的会话，每条附带其恢复命令，并给当前会话标注 `(current)`。当 `resumeCommand` 未配置或未挂载持久化后端时给出告警，尚无任何会话被持久化时给出提示。列出是异步的，因此提交后文本记录会在下一个 tick 更新。
-- **列出逻辑。** `listWorkspaceSessions()` 读取可选的 `sessionPersistence` 服务的 `list()`，保留 `cwd === agent.session.header.cwd` 的头部，并按 `createdAt` 降序排序。`list()` 拒绝时吞掉为 `[]`——持久化失败绝不能阻塞终端退出或让 `/resume` 崩溃。
+`session-query.readSession()` 提供一份脱离运行时的完整日志，并通过恢复流程所用的同一核心回放边界完成验证。TUI 从该日志中折叠出标题和目标状态。候选项加载失败时只影响该行；选择候选项后会复查日志、`cwd`、路由、当前 agent 的空闲状态，以及针对当前会话和已在本运行时中处于活跃状态的会话的排除规则，避免陈旧列表绕过预检。适配器缺失时会报告会话完整但路由不可用。该预检不会锁定目标，也不会排除其他进程。
-`sessionPersistence` 是一个通过 `ctx.get('sessionPersistence')`（而非 `inject`）获取的可选注入服务，声明为可选的对等依赖（peer dependency）。没有后端时该字段仍能解析；退出提示与 `/resume` 分别退化为不做任何事、以及给出未配置/无后端告警。`dsh-tui-demo` 将 `resumeCommand` 转发给 `dsh-tui`，可运行的 `examples/tui-agent` 叶子配置设为 `dsh --resume {session}`。`dsh` CLI（`apps/cli`）通过 [`dsh-app-boot`](../../../../packages/ui/app-boot/README.md) 中的 `parseResumeArg` 解析该 `--resume <id>` 标志，在启动前设置 `RESUME_SESSION_ID`，因此打印出的命令会重新走回配置中既有的 `resumeSessionId` 入口；拼写错误或重复的标志会直接报错退出，而非悄悄开启一个新会话。
+预检通过后，TUI 会刷写当前会话，再次确认其 agent 仍处于空闲状态，然后停止终端并调用 `TuiRuntime.handoffResume`。已交付的 `dsh` 宿主会释放根应用，并使用带有规范化 `--resume` 参数的 `process.execve` 原子替换当前进程，而不是启动子进程。恢复后的应用发布相同的 `SessionId`；常规回放会还原 transcript（文本记录）、标题、待办事项和持久化目标状态。系统会有意解除目标的激活状态，TUI 则要求用户确认继续或执行 `/goal resume`。
+
+`resumeCommand` 保留为退出及无宿主时的回退方案。TUI 仅为显示目的替换 `{session}`，绝不执行任意 shell 文本。只有当前会话已经持久化时，退出提示才会出现。
## Alternatives considered
-**硬编码或自动探测恢复调用命令。** 否决：启动命令与部署强相关——环境变量名、可执行文件、参数都各不相同——因此一个 `DEFAULT_*` 常量只会是固定的可调项，而非可配置项。由叶子拥有的模板把这个选择留在部署所在之处，而 `{session}` 是 TUI 唯一需要知道的替换。
+**让 TUI 创建 `resumeCommand` 进程。** 否决：该模板是部署文本，不是可信的参数列表，且 TUI 不拥有应用拆卸或进程生命周期。受约束的宿主接口只接收经过验证的 `SessionId`。
-**两个配置字段，每处出口一个。** 否决：两处渲染的是完全相同的命令，因此单个字段让它们保持对称、不会漂移；不存在只想要提示而不想要列表的部署。
+**在现有 TUI 内构造恢复后的 agent。** 否决：在表现层替换由配置创建的 agent，会跨越 Loader 所有权、作用域插件初始化、持久化资源释放和终端生命周期。释放根应用并替换进程可以复用受支持的启动路径。
-**无条件打印退出提示。** 否决：恢复一个从未刷盘的会话 id 会加载失败，宣传它就是一条错误指令。以 id 是否出现在 `list()` 中为条件仅需一次扫描，且只会抑制一条注定失败的命令。
+**把适配器缺失视为会话缺失。** 否决：存储有效性和当前路由可用性是相互独立的事实。选择器会保留该行，并指出不可用的提供方／模型。
-**从 `/resume` 就地恢复（重启或重连）。** 否决：TUI 不拥有 agent 生命周期或进程创建（[全屏 TUI 门面 Agent Note](2026-07-17-dedicated-full-screen-tui-front-door.md)）。打印一条可复制的命令尊重这条边界，也契合需求所引用的 `pi --resume` 用法。
-
-**把 `sessionPersistence` 设为必需的 `inject`。** 否决：TUI 必须能在无持久化时运行（fixture（测试前置数据）、临时运行）。一个会优雅退化的可选服务保住了这一点，也与 [`session-query`](../../../../packages/session-query/session-query/package.json) 对同一可选对等依赖的先例一致。
+**恢复会话时延续目标激活状态。** 否决：持久意图并不代表跨越用户或进程边界后仍获授权继续执行。目标阶段会保留，但不会自动续跑。
## Consequences
-- `dsh-tui` 新增对 `@deepseek-ai/dsh-session-persistence` 的可选对等依赖（`peerDependenciesMeta.optional`），与 `session-query` 一致；未挂载后端时该包仍能加载并通过其覆盖率门禁。
-- 帮助行和自动补全新增 `/resume`；两个既有快照因帮助行变宽而重新录制，新增的 `resume-sessions` 检查点固定渲染出的列表。
-- `dsh-tui-demo` 及两个 `examples/tui-agent` 叶子配置都带上 `resumeCommand`，因此真实的 TUI 运行现在退出时会打印自己的恢复命令，且 `dsh` CLI 接受打印出的 `--resume <id>` 标志来运行它。
+- 预检不会串行化不同进程；多个进程可以并发选择或恢复同一个持久化会话。
+- `/resume` 依赖 `session-query` 发现会话并读取完整日志，但持久化和宿主交接仍是可选功能；没有宿主时，命令回退仍可使用。
+- 进程替换会有意重启 Loader 组合。系统会重建仅存在于运行时的状态，而只有日志或会话头部记录的会话状态能够保留。
## Testing
-`packages/ui/tui/tests/tui.spec.ts` 固定这七种行为：退出提示仅在当前会话已持久化时打印，未持久化时以及 `list()` 拒绝时都不打印；`/resume` 按最新在前列出 workspace 会话并带 `(current)` 标注与 cwd 过滤、未配置时告警、无后端时告警、尚无持久化时给出提示。`resume-sessions` 快照验证完整渲染帧。测试脚手架通过 `ctx.provide` 提供一个假的 `sessionPersistence`。对于 `--resume` 标志，`packages/ui/app-boot/tests/app-boot.spec.ts` 固定 `parseResumeArg`（空格形式与内联形式、位置无关性，以及在标志缺值、为空或重复时直接报错退出），`examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` 用 `--resume <missing-id>` 启动 `apps/cli` 并断言配置恢复直接报错退出——证明该标志抵达了 `resumeSessionId` 入口。
+TUI 测试覆盖键盘导航、标题／id 搜索、清空搜索后再取消、agent 运行期间拒绝恢复、拒绝恢复当前会话和已在本运行时中处于活跃状态的会话、路由缺失、损坏的候选行、预检复查、回退命令，以及停止终端先于宿主交接的顺序。session-query 测试固定脱离运行时的完整日志验证。agent-loop 恢复测试固定会话身份和历史完全一致；标题、待办事项和目标回放测试套件固定这些投影均可恢复，且目标激活状态已经解除。无密钥 TUI 快照固定全屏选择页和输入法光标锚点，真实 PTY smoke 则覆盖搜索与交接。

+# Agent Note: Trajectory step cell and turn list chrome
+
+Status: implemented
+
+English | [中文](2026-07-23-trajectory-step-cell.zh.md)
+
+## Problem
+
+The trajectory tab needs a reusable step row and turn-list chrome that can show expanded assistant blocks, own-duration times, Message token columns, and in-flight work. Without folding session event times into conversation nodes and expanding blocks into cells, the UI cannot match the product chrome.
+
+## Decision
+
+[`@deepseek-ai/dsh-client-ui-trajectory`](../../../../packages/client/ui-trajectory/README.md) owns the presentational trajectory list chrome:
+
+- [`TrajectoryCell`](../../../../packages/client/ui-trajectory/src/client/TrajectoryCell.tsx) — 38px step row with kinds User / Message / Tool (no Think, Call, or Result rows). Reasoning blocks are skipped (no block-level clock). Each `tool-call` + paired `tool-result` folds into one Tool row (`name ·` truncated args) whose Time is `result.time − callTime` when both are known. Message rows carry Input/Output/Think token columns from `assistant.usage`. Own-duration Time uses `+Ns` / `+N.1s`, or `—` when absent. Selected state draws a 2px inset `--dsw-alias-brand-primary-new-colorprimary-new-color` ring (`selected` prop) and is not wired to chat selection.
+- [`TrajectoryTurn`](../../../../packages/client/ui-trajectory/src/client/TrajectoryTurn.tsx) / header / group header — sticky Turn bar paints full-bleed `ghost-active-fill`; title/columns and the Message/Step body sit in a centered `max-width: 880px` lane. Cell trailing columns share the Turn header geometry (`320 = 4×71 + 3×12`); cells use pad 20/8.
+- [`deriveTrajectoryLayout`](../../../../packages/client/ui-trajectory/src/client/layout.ts) expands assistant `blocks[]` into cells, pairs tool-calls with `tool-result` by `callId` into Tool, folds `partial` and `runningCalls` (deduped), hangs usage on Message only (including the empty fallback when there is no text block), and builds group descriptions as wall-span + tool histogram (`1.5s bash×6`). `user/message` has no wire turn, so each User row is enclosed in the next assistant/steering turn, else the in-flight `partial` turn, else `lastAssistantTurn + 1` (or `1`). Context nodes emit no cell but still advance the Message duration cursor.
+
+[`ConversationNode`](../../../../packages/client/runtime/src/client/sessions/conversation.ts) carries `time` from `SessionEvent.time`; `ToolResultNode.callTime` and `RunningToolCall.time` come from the paired `tool/call`. Duration rules: User `+0s`; Message = assistant.time − previous surface time (including skipped context); Tool = result.time − callTime when both known; in-flight Tool = `—`. Group header duration is earliest→latest absolute time in the group (wall span; Tool contributes start and start+duration).
+
+## Alternatives considered
+
+**Keep a Think cell for reasoning blocks.** Rejected: a single `assistant/message.time` cannot yield Think own-duration without chunk-level clocks; omit the row rather than show `—`.
+
+**Keep separate Call and Result rows.** Rejected: Result had no own duration to show; one Tool row carries the call→result interval.
+
+**Cumulative elapsed from session/turn start.** Rejected; the Time column is each row's own duration.
+
+**Hang usage on the first expanded row.** Rejected; usage attaches to Message only.
+
+**Show in-flight tool durations via Date.now().** Deferred; in-flight Time stays `—`.
+
+## Consequences
+
+The Trajectory tab can render expanded finalized and in-flight rows with own-duration times once fold emits `time`. Behavior-shaped coverage lives in `packages/client/ui-trajectory/tests/{cell,layout,views}.spec.tsx`. Chat selection deep-links and finer block-level clocks remain deferred.

+Status: implemented
+
+[English](2026-07-23-trajectory-step-cell.md) | 中文
+
+## Problem
+
+trajectory 标签页需要可复用的步骤行与轮次列表 chrome，以展示展开后的 assistant 块、自身耗时、Message token 列，以及进行中的工作。若不将会话事件时间折叠进会话节点，并将块展开为单元格，UI 就无法对齐产品 chrome。
+
+## Decision
+
+[`@deepseek-ai/dsh-client-ui-trajectory`](../../../../packages/client/ui-trajectory/README.md) 拥有展示型 trajectory 列表 chrome：
+
+- [`TrajectoryCell`](../../../../packages/client/ui-trajectory/src/client/TrajectoryCell.tsx) — 高 38px 的步骤行，类型为 User / Message / Tool（无 Think、Call、Result 行）。reasoning 块跳过（无块级时钟）。每对 `tool-call` + `tool-result` 折成一行 Tool（`name ·` 加截断参数），Time 在两端皆知时为 `result.time − callTime`。Message 行携带来自 `assistant.usage` 的 Input/Output/Think token 列。自身耗时 Time 使用 `+Ns` / `+N.1s`，缺失时为 `—`。选中态绘制 2px 内嵌的 `--dsw-alias-brand-primary-new-colorprimary-new-color` 环（`selected` prop），且未接线到 chat 选中。
+- [`TrajectoryTurn`](../../../../packages/client/ui-trajectory/src/client/TrajectoryTurn.tsx) / header / group header — 粘性 Turn 条背景通栏铺 `ghost-active-fill`；标题／列标与 Message/Step 主体落在居中的 `max-width: 880px` 内容道。单元格右侧列与 Turn 标头共用几何（`320 = 4×71 + 3×12`）；cell pad 20/8。
+- [`deriveTrajectoryLayout`](../../../../packages/client/ui-trajectory/src/client/layout.ts) 将 assistant `blocks[]` 展开为单元格，按 `callId` 将 tool-call 与 tool-result 配对为 Tool，折叠 `partial` 与 `runningCalls`（去重），仅将用量挂在 Message 上（含无 text 块时的空回退行），并以墙钟跨度 + 工具直方图构建分组描述（`1.5s bash×6`）。`user/message` 无线上 turn，故每条 User 行归入下一 assistant/steering 的 turn，否则归入进行中的 `partial` turn，否则为 `lastAssistantTurn + 1`（或 `1`）。context 节点不产出单元格，但仍推进 Message 耗时游标。
+
+[`ConversationNode`](../../../../packages/client/runtime/src/client/sessions/conversation.ts) 携带来自 `SessionEvent.time` 的 `time`；`ToolResultNode.callTime` 与 `RunningToolCall.time` 来自配对的 `tool/call`。耗时规则：User 为 `+0s`；Message = assistant.time − 上一表面时间（含跳过的 context）；Tool = 在两者皆知时 result.time − callTime；进行中 Tool = `—`。分组标头耗时为组内最早→最晚绝对时间（墙钟跨度；Tool 贡献起点与起点+自身耗时）。
+
+## Alternatives considered
+
+**为 reasoning 块保留 Think 单元格。** 否决：单条 `assistant/message.time` 无法给出 Think 自身耗时（除非上 chunk 级时钟）；与其显示 `—`，不如省略该行。
+
+**保留分开的 Call 与 Result 行。** 否决：Result 没有可展示的自身耗时；一行 Tool 承载 call→result 区间。
+
+**自会话／轮次起点累计耗时。** 否决；Time 列是每行自身的耗时。
+
+**将用量挂在展开后的第一行。** 否决；用量仅附着于 Message。
+
+**用 Date.now() 显示进行中工具的耗时。** 延后；进行中的 Time 保持为 `—`。
+
+## Consequences
+
+一旦 fold 发出 `time`，Trajectory 标签页即可渲染带自身耗时的已定稿与进行中展开行。行为导向的覆盖位于 `packages/client/ui-trajectory/tests/{cell,layout,views}.spec.tsx`。chat 选中深链与更细的块级时钟仍延后。

+# Agent Note: Model-facing session query tools
+
+Status: implemented
+
+English | [中文](2026-07-24-model-facing-session-query-tools.zh.md)
+
+## Problem
+
+The unified `ctx.sessionQuery` service exposes exact reads, filters, relationship traces, and full-text search over live-preferred session logs, but models cannot use that service directly. Giving a model the provider request types would also expose unstable pagination cursors, trusted corpus scope, storage-shaped time values, and result records that are more convenient for programmatic consumers than for reasoning. Large traces and event payloads introduce a separate output-size concern, but solving that concern inside this consumer would duplicate the harness-wide spill mechanism and make session-query tools disagree with other tools.
+
+## Decision
+
+`@deepseek-ai/dsh-tool-session-query` is the model-facing consumer of `ctx.sessionQuery`. It registers five narrow read-only tools: `session_search`, `session_event_search`, `session_trace`, `session_event_trace`, and `session_event_read`. The package imports the interface rather than the SQLite implementation, owns model argument validation and readable text rendering, and contributes one concise prompt section that teaches the prior-history search and search-to-trace/read workflow.
+
+The package entrypoint is only the public composition root for configuration, prompt registration, and tool registration. Its internal modules follow the execution boundary: `input.ts` owns model schemas, normalization, and filter construction; `service-boundary.ts` contains provider calls and model-safe error translation; `workspace-access.ts` owns caller identity, workspace authorization, title access, and lineage projection; `operations.ts` orchestrates the five service workflows; and `presentation.ts` renders tool results and call cards. This keeps policy in its owning layer without changing the package contract.
+
+`session_search` groups full-text matches by session and exposes typed session and event metadata filters. `session_event_search` searches one session, defaulting to the caller's current session. `session_trace` returns the complete authorized ancestor chain and recursive descendant trees. `session_event_trace` returns every known positional replacement and direct provenance relationship for one event. `session_event_read` returns the exact target event as unabridged JSON and optionally summarizes a bounded raw-event window; omitted `before` and `after` values mean target-only.
+
+Model-facing filters use flat snake-case fields. Timestamps are timezone-qualified ISO 8601 strings at the tool boundary, convert to inclusive epoch-millisecond ranges for the service, and render as UTC ISO 8601. List values are ORed inside one filter while separate filters are ANDed. Requested parent ids are deduplicated and authority-filtered before FTS, so only parents in the caller workspace enter the provider clause; missing and cross-workspace guesses behave identically, while the root-session marker remains independently ORed into that clause. Event type strings remain open because `SessionEventMap` is merge-extensible; availability and event surface use closed values.
+
+## Workspace authority
+
+Every executor derives its caller from immutable `ToolExecution.exec.agent` identity and never accepts a model-supplied workspace. A target is authorized only when its observed `cwd` exactly equals the caller session's `cwd`. Cross-session search always adds that workspace filter. Direct operations preflight the target and then validate the header returned from the same service observation as every event-search page, event trace, event read, lineage target, or folded title before rendering its payload. This prevents a live or persisted target replacement between the check and use from crossing the workspace boundary. Lineage rendering stops at an unauthorized ancestor or descendant subtree without revealing the hidden session id. A caller whose session has no `cwd` can inspect only its own session; missing agent identity fails closed.
+
+Every trusted `ctx.sessionQuery` call crosses one model-boundary sanitizer. It checks the execution signal first, preserving caller cancellation exactly. For other failures it records the available corpus or provider diagnostic chain in the internal log on a best-effort basis, substituting a fixed placeholder when the value cannot be safely inspected. Diagnostic formatting and error classification are independently guarded, so an unprintable nested cause cannot escape or prevent a safely classified outer error, while unsafe classification or logging returns the fixed generic `SESSION_QUERY_TOOL_FAILED` code and message. Per-title failures use the same sanitizer before becoming unavailable markers. Tool-owned input-validation and authorization errors remain precise because they are created outside this service boundary.
+
+The search tools expose prior work rather than the operation that is performing the search. `session_search` omits the caller's session. When `session_event_search` targets the caller's session, it intersects the requested sequence range with the event immediately before the current `step/start`, excluding the current assistant message and tool call as well as the query arguments indexed from that call.
+
+## Cursor-free results and spill
+
+Neither search tool exposes a cursor, offset, page size, or model-controlled result limit. One execution follows provider cursors while the observed generation remains valid and collects up to the configured `maxSearchResults`, which defaults to 100. A capped result tells the model to narrow its query or filters; a generation change reports that the whole search must be retried. Search execution carries a configurable `searchTimeoutMs`, defaulting to 30 seconds, through the tool deadline and the service abort signal. Because internal pages share generation-bound cursors, both search tools are exclusive in the agent-loop scheduler; the exact trace and read tools opt into parallel sibling execution because their observations tolerate intervening commits.
+
+Trace and read tools likewise expose no lineage or character pagination. Canonical results are plain text and remain complete within the service's existing event-window and search-count resource bounds. Each exact executor passes its unchanged tool-execution signal through target authorization and the service trace or read. Within service resolution, known-live event traces, event reads, and title reads remain persistence-free while honoring pre-abort. Session lineage tracing passes the signal to whole-corpus persistence listing; persisted event tracing and reading pass it to target listing and inspection. Each started backend call is awaited for cleanup before the exact abort reason is preserved, even when that backend ignored cancellation. The generic `tools/post-execute` spill policy owns inline byte retention: when a configured deployment receives oversized text, it replaces that text with a bounded preview plus an opaque locator and retrieval hint while preserving the complete result in its spill store. The session-query consumer neither imports `ctx.spillStore` nor implements a second truncation format.
+
+Session-level results include the latest folded title when available. Each tool execution batches its unique title ids through one live-preferred corpus observation with at most the service's configured `persistedInspectConcurrency` workers, which defaults to four, and passes the exact tool-execution signal through persisted listing and inspection. Live sources fold directly; each persisted worker folds its completed source to a detached header/title observation and releases the full log before dequeuing another id, so the batch retains only small projected values. For the search tools, the execution signal carries the configured search deadline. Cancellation starts no queued title inspections and rejects the complete tool execution after already-started inspections settle; a missing, malformed, or operationally failed title remains isolated to that id, preserves the base result, renders an unavailable marker, and logs the underlying error, while an authorization mismatch fails closed. Search results include the strongest matching event and provider excerpt, traces include complete authorized relationships, and event reads keep neighbor presentation readable while reserving exact JSON for the requested target.
+
+## Host composition
+
+The consumer is an opt-in plugin. The shipped ACP and TUI apps mount `ctx.sessionQuery` for non-model consumers, while the shared Web/headless composition mounts neither the query service nor the consumer. No shipped composition mounts `@deepseek-ai/dsh-tool-session-query`, so default model requests gain no query prompt or schemas. A composition that opts in also chooses whether to mount the generic timeout and spill policies; the dedicated ACP snapshot fixture mounts both and uses private local spill storage. Generic tool presentation requires no session-query-specific client plugin.
+
+## Alternatives considered
+
+- **Expose provider cursors to the model** — rejected because recording a tool result or starting the next model step changes the relevant session or global generation, so a cursor is usually stale before the model can reuse it.
+- **Add tool-local truncation, offsets, or spill files** — rejected because the post-execute spill policy already owns complete-result retention and retrieval across tools.
+- **Allow every persisted session or model-supplied workspace filters** — rejected because `ctx.sessionQuery` is a trusted service and the model-facing consumer must enforce the caller's authority boundary.
+- **Combine search, tracing, and exact reads into one operation selector** — rejected because narrow names give the model clearer schemas, defaults, presentation intents, and follow-up choices.
+- **Return only one lineage hop** — rejected because spill removes the inline-size motivation while one-hop output would omit relationships with no continuation path.
+
+## Verification
+
+Package tests pin argument validation, filter translation, timestamp normalization, exact-workspace authorization, parent-filter preauthorization and oracle resistance, changed-observation rejection, service-diagnostic redaction for ordinary and adversarial unknown values, best-effort cyclic-cause logging, logger-failure containment, missing-identity behavior, hidden-boundary pruning, current-step exclusion, internal provider paging, exclusive search and parallel exact-read classification, count caps, exact-signal forwarding, abort-reason preservation, persistence cleanup quiescence, one-scan bounded batch title enrichment, projection-before-dequeue ordering, queued-work suppression, started-worker quiescence, per-header validation, title fallbacks, representative search/trace/read rendering, generic presentation, and disposable registration. Integration coverage uses the real SQLite FTS provider over live and persisted sessions. Shipped configuration, app composition tests, and assembled ACP request-header snapshots prove that the model-facing consumer remains absent while `ctx.sessionQuery` stays available where mounted. A package-owned Loader smoke and dedicated keyless ACP snapshot explicitly mount the consumer with timeout and spill support, pinning its prompt guidance, schemas, and path-independent exact event-read retention behavior.
+
+## Consequences
+
+Models gain provider-independent access to prior session work without receiving storage authority or continuation state. Search has a finite per-call work bound and may require a narrower query to reach matches beyond the first 100; search calls cannot overlap siblings, while exact observations retain parallel scheduling. Complete traces and event payloads may become spill references instead of inline text. Exact string `cwd` equality favors a conservative security boundary over resolving symlink-equivalent paths. Custom compositions may mount the tool without spill, but then they explicitly accept complete inline trace and read results.

+# Agent Note: 面向模型的会话查询工具
+
+Status: implemented
+
+[English](2026-07-24-model-facing-session-query-tools.md) | 中文
+
+## 问题
+
+统一的 `ctx.sessionQuery` 服务对优先使用实时数据的会话日志提供精确读取、过滤、关系追踪与全文搜索，但模型无法直接使用该服务。若把提供方请求类型交给模型，还会暴露不稳定的分页游标、受信任的语料范围、存储形态的时间值，以及更适合程序化消费者而非模型推理的结果记录。大型追踪与事件负载另有输出大小问题，但若在该消费者内部解决，就会重复 harness 的通用 spill 机制，并使会话查询工具与其他工具的行为不一致。
+
+## 决策
+
+`@deepseek-ai/dsh-tool-session-query` 是 `ctx.sessionQuery` 面向模型的消费者。它注册五个职责单一的只读工具：`session_search`、`session_event_search`、`session_trace`、`session_event_trace` 和 `session_event_read`。该包依赖接口而非 SQLite 实现，负责模型参数校验与易读文本渲染，并贡献一个精简的提示词段，说明历史搜索以及从搜索转向追踪／读取的工作流。
+
+该包入口仅作为配置、提示词注册与工具注册的公开组合根。内部模块沿执行边界划分：`input.ts` 负责模型 schema、规范化与过滤条件构造；`service-boundary.ts` 包含提供方调用与面向模型的安全错误转换；`workspace-access.ts` 负责调用者身份、工作区授权、标题访问与谱系投影；`operations.ts` 编排五个服务工作流；`presentation.ts` 渲染工具结果与调用卡片。这样可让策略留在其所属层，同时不改变包契约。
+
+`session_search` 按会话聚合全文匹配，并公开带类型的会话与事件元数据过滤条件。`session_event_search` 搜索一个会话，默认目标为调用者的当前会话。`session_trace` 返回完整的已授权祖先链与递归后代树。`session_event_trace` 返回一个事件所有已知的位置替换关系与直接来源关系。`session_event_read` 以未删节 JSON 返回准确的目标事件，并可选择汇总一个有界的原始事件窗口；省略 `before` 与 `after` 时只返回目标。
+
+面向模型的过滤条件使用扁平的 snake-case 字段。工具边界上的时间戳采用带时区的 ISO 8601 字符串，转换为服务使用的闭区间毫秒时间戳，并以 UTC ISO 8601 渲染。同一个过滤条件中的列表值按 OR 组合，不同过滤条件按 AND 组合。请求的父会话 id 会在 FTS 之前去重并按权限过滤，因此只有调用者工作区中的父会话会进入提供方条件；缺失与跨工作区的猜测具有相同行为，而根会话标记仍会独立按 OR 加入该条件。由于 `SessionEventMap` 可通过声明合并扩展，事件类型字符串保持开放；可用状态与事件表层使用封闭取值。
+
+## 工作区权限
+
+每个执行器都从不可变的 `ToolExecution.exec.agent` 身份推导调用者，绝不接受模型提供的工作区。只有当目标观测中的 `cwd` 与调用者会话的 `cwd` 完全相同时，目标才获授权。跨会话搜索始终附加该工作区过滤条件。直接操作先预检目标，然后在渲染负载前，校验与每一页事件搜索结果、事件追踪、事件读取、谱系目标或折叠标题来自同一服务观测的会话头。这样，即使实时或持久化目标在检查与使用之间被替换，也无法跨越工作区边界。谱系渲染在遇到未授权的祖先或后代子树时停止，且不泄露被隐藏的会话 id。调用者会话没有 `cwd` 时只能检查自身会话；缺少 agent 身份时按失败关闭处理。
+
+每个受信任的 `ctx.sessionQuery` 调用都会经过同一个模型边界净化器。它首先检查执行信号，准确保留调用者取消。对于其他失败，它会尽力把可获得的语料或提供方诊断链写入内部日志；当值无法安全检查时，则改用固定占位符。诊断格式化与错误分类各自受到保护，因此无法打印的嵌套 cause 既不会逃逸，也不会阻止对外层错误进行安全分类；分类不安全或日志记录失败时，则返回固定的通用错误码 `SESSION_QUERY_TOOL_FAILED` 及其消息。逐标题失败也会先经过同一个净化器，再转为不可用标记。工具自身的输入校验与授权错误在该服务边界之外创建，因此仍保留精确消息。
+
+搜索工具公开的是既往工作，而不是正在执行搜索的操作本身。`session_search` 排除调用者会话。`session_event_search` 以调用者会话为目标时，会把请求的序号范围与当前 `step/start` 之前的最后一个事件取交集，从而排除当前 assistant 消息、工具调用，以及从该次调用中建立索引的查询参数。
+
+## 无游标结果与 spill
+
+两个搜索工具都不向模型公开游标、偏移量、页大小或模型可控的结果限制。一次执行会在观察到的代保持有效时持续跟随提供方游标，并收集不超过配置项 `maxSearchResults` 的结果，其默认值为 100。达到上限的结果会要求模型缩小查询或过滤范围；代发生变化时会报告必须重试完整搜索。搜索执行通过工具截止时间与服务中止信号传递可配置的 `searchTimeoutMs`，默认值为 30 秒。由于内部页面共享与代绑定的游标，两个搜索工具在 agent loop 调度器中都以独占方式执行；精确追踪与读取工具则允许和兄弟工具并行执行，因为其观测可以容忍期间发生的提交。
+
+追踪与读取工具同样不公开谱系分页或字符分页。规范结果采用纯文本，并在服务已有的事件窗口与搜索数量资源边界内保持完整。每个精确执行器都会将未经替换的工具执行信号传递给目标授权与服务追踪或读取。在服务解析过程中，已知实时事件追踪、事件读取与标题读取在遵循预中止的同时仍不访问持久化。会话谱系追踪会将该信号传递给全语料持久化列表；持久化事件追踪与读取则将其传递给目标列表和检查。每个已启动的后端调用都会等待清理完成后再保留准确的中止原因，即使该后端忽略了取消也不例外。通用的 `tools/post-execute` spill 策略负责行内字节保留：当已配置的部署收到过大的文本时，该策略会用有界预览、不可透明推导的定位符与读取提示替换文本，同时在 spill 存储中保留完整结果。会话查询消费者既不导入 `ctx.spillStore`，也不实现第二套截断格式。
+
+会话级结果在可用时包含最新折叠标题。每次工具执行都会通过一次优先使用实时数据的语料观测批量读取唯一标题 id，最多使用服务通过 `persistedInspectConcurrency` 配置的持久化检查 worker，其默认值为 4，并将准确的工具执行信号传递给持久化列表与检查操作。实时来源会直接折叠；每个持久化 worker 都会把已完成的来源折叠为分离的会话头／标题观测，并在取出下一个 id 前释放完整日志，因此批次只保留小型投影值。对于搜索工具，该执行信号携带已配置的搜索截止时间。取消不会启动排队中的标题检查，并会在已经启动的检查全部完成后拒绝完整的工具执行；标题缺失、格式错误或发生操作性失败时，错误只影响对应 id，同时保留基础结果、渲染不可用标记并记录底层错误，而授权不匹配则按失败关闭处理。搜索结果包含最强匹配事件与提供方摘录，追踪包含完整的已授权关系，事件读取保持邻近事件表现易读，同时只为被请求的目标保留精确 JSON。
+
+## 宿主组合
+
+该消费方是一个需显式启用的插件。发布的 ACP 与 TUI 应用为非模型消费方挂载 `ctx.sessionQuery`，而 Web/headless 共享组合既不挂载查询服务，也不挂载该消费方。发布的组合均未挂载 `@deepseek-ai/dsh-tool-session-query`，因此默认模型请求中不包含查询提示词或 schema。选择启用该插件的组合还要决定是否挂载通用的超时与 spill 策略；专用的 ACP 快照 fixture（测试前置数据）同时挂载这两项策略，并使用私有的本地 spill 存储。通用工具表现无需会话查询专用客户端插件。
+
+## 考虑过的替代方案
+
+- **向模型公开提供方游标**：不予采纳，因为记录工具结果或开始下一个模型步骤会改变相关会话或全局代，导致游标通常在模型能够复用前就已过期。
+- **增加工具本地截断、偏移量或 spill 文件**：不予采纳，因为执行后 spill 策略已经统一负责各工具的完整结果保留与读取。
+- **允许访问所有持久化会话或由模型提供工作区过滤条件**：不予采纳，因为 `ctx.sessionQuery` 是受信任服务，面向模型的消费者必须执行调用者权限边界。
+- **把搜索、追踪与精确读取合并为一个带操作选择器的工具**：不予采纳，因为职责单一的名称能为模型提供更清晰的 schema、默认值、表现意图与后续选择。
+- **只返回一层谱系**：不予采纳，因为 spill 已消除行内大小方面的理由，而单层输出会遗漏关系且没有继续读取路径。
+
+## 验证
+
+包级测试固定参数校验、过滤条件转换、时间戳规范化、精确工作区授权、父级过滤预授权与抵御预言机探测、变更观测拒绝、普通值与对抗性未知值的服务诊断脱敏、尽力记录循环 cause、日志失败隔离、身份缺失行为、隐藏边界裁剪、当前步骤排除、内部提供方翻页、搜索独占与精确读取并行分类、数量上限、精确信号传递、中止原因保留、持久化清理静止、单次扫描且并发有界的批量标题扩充、先投影再取出下一个任务的顺序、抑制排队工作、等待已启动 worker 静止、逐会话头校验、标题回退、代表性搜索／追踪／读取渲染、通用表现与可释放注册。集成覆盖使用真实 SQLite FTS 提供方查询实时与持久化会话。发布配置、应用组合测试与组装后的 ACP 请求头快照证明：面向模型的消费方仍未挂载，而 `ctx.sessionQuery` 在已经挂载该服务的组合中保持可用。包自身的 Loader 冒烟测试与专用无密钥 ACP 快照显式挂载该消费方，并配套启用超时与 spill 支持，固定其提示词指引、schema 以及与路径无关的精确事件读取保留行为。
+
+## 后果
+
+模型无需获得存储权限或继续状态，即可通过与提供方无关的方式访问既往会话工作。搜索具有有限的单次调用工作边界，若要命中前 100 条以后的结果，可能需要缩小查询；搜索调用不能与兄弟工具重叠执行，而精确观测仍可并行调度。完整追踪与事件负载可能表现为 spill 引用而不是行内文本。严格的 `cwd` 字符串相等选择了保守安全边界，而不解析通过符号链接等价的路径。自定义组合可以在不挂载 spill 的情况下使用该工具，但这表示它们明确接受完整追踪与读取结果直接出现在行内。

+# Agent Note: New Session clears onto the empty-state launch
+
+Status: implemented
+
+English | [中文](2026-07-24-new-session-clears-to-empty-state.zh.md)
+
+## Problem
+
+Sidebar "New Session" created and opened a blank session immediately, so the center column showed `ConversationRoot` with an empty transcript and the resident composer. The Figma NEW SESSION screen (`EmptyState` + shared `InputBar` hero) only rendered when `sessions.current` was already undefined, so the launch page was unreachable from the primary creation control.
+
+## Decision
+
+`SessionsService.clear()` wipes the persisted selection and `list.current`. Top-level sidebar creation entries (`onCreate()` with no cwd — New Session and New Workspace) call `clear()` so `AppFrame` renders `conversation.empty`. The empty state's first send still runs `conversation.startSession` (create → open → send) and reuses the same `InputBar` component as the resident composer (`variant="hero"`). Per-project "+" (`onCreate(cwd)`) keeps create-then-open until the empty-state picker can accept a seeded cwd.
+
+## Alternatives considered

+**Keep create-then-open for New Session and add a second empty chrome inside ConversationRoot when the transcript is empty.** Rejected: that duplicates the launch InputBar and breaks the empty→content ruling that one InputBar moves position rather than swapping components.
+
+**Route New Session through a dedicated route or slot outside selection.** Rejected for this pass: `conversation.empty` already owns the launch UI; clearing `current` is the existing empty branch.
+
+## Consequences
+
+New Session no longer mints a host session until the first send. Reloading after clear stays on the empty state. Project-scoped "+" still creates immediately. `EmptyState` stacks the Figma hero (Input_Bottom 75:8208) as fish + title, a Menu-backed workspace chip above the card, then shared `InputBar` (`variant="hero"`, max-width 800, r20 card matching the composer — not a taller r24 hero), with a soft ellipse glow (figma 313:14109) centered behind the picker + card and width-locked to the card (`1051/776` asset ratio) so it scales with it. The chip uses the soft interactive hover fill + 12px radius from 75:8208 and opens MenuDropdown (figma 122:9481; `--dsw-specific-menu` + `--dsw-shadow-lv3`): basename rows with folder icons and a trailing check, then a separator and "New Workspace" whose submenu (figma 419:16920) offers "Use a existing folder" and "Create new". Use a existing folder opens the path Dialog (figma 451:18655 copy — "Enter an existing folder path" / Open Folder) over a full-viewport mask (`--dsw-alias-bg-mask-1` + `--dsw-mask-blur`) and sets the chip cwd. Create new opens the same Dialog chrome to name a folder under `host.describe().cwd`; success runs `sessions.createWorkspace` → host `session.create` (mkdir recursive) → `sessions.open`, so a default session lands in the new workspace. `InputBar` paints the bottom chrome (attach / Plan / Read-only / model) with local native `<select>` state only — host plan, access, and model seams remain unwired.

+# Agent Note: New Session clears onto the empty-state launch
+
+Status: implemented
+
+[English](2026-07-24-new-session-clears-to-empty-state.md) | 中文
+
+## Problem
+
+侧栏「New Session」会立即创建并打开空白会话，因此中间栏显示带空 transcript（文本记录）与常驻 composer 的 `ConversationRoot`。Figma 的 NEW SESSION 屏（`EmptyState` + 共用的 `InputBar` hero）仅在 `sessions.current` 已为 undefined 时渲染，因而主创建控件无法到达启动页。
+
+## Decision
+
+`SessionsService.clear()` 清除持久化选中项与 `list.current`。顶层侧栏创建入口（无 cwd 的 `onCreate()`——New Session 与 New Workspace）调用 `clear()`，使 `AppFrame` 渲染 `conversation.empty`。空态的首次发送仍走 `conversation.startSession`（create → open → send），并复用与常驻 composer 相同的 `InputBar` 组件（`variant="hero"`）。按项目的「+」（`onCreate(cwd)`）继续 create-then-open，直到空态选择器能接受预填的 cwd。
+
+## Alternatives considered
+
+**为 New Session 保留 create-then-open，并在 transcript 为空时于 ConversationRoot 内再加一套空态 chrome。** 否决：这会重复启动页的 InputBar，并破坏 empty→content 的约定——同一 InputBar 应移动位置，而非互换组件。
+
+**将 New Session 路由到选中状态之外的专用 route 或 slot。** 本轮否决：`conversation.empty` 已拥有启动 UI；清除 `current` 即是既有的空态分支。
+
+## Consequences
+
+New Session 在首次发送前不再创建 host 会话。clear 后重新加载仍停留在空态。项目范围的「+」仍立即创建。`EmptyState` 按 Figma 堆叠英雄区（Input_Bottom 75:8208）：鱼标 + 标题、卡片上方由 Menu 驱动的工作区 chip，再接共用的 `InputBar`（`variant="hero"`，max-width 800，与 composer 一致的 r20 卡片——而非更高的 r24 英雄区），选择器与卡片背后居中铺一层柔光椭圆（figma 313:14109），宽度按卡片锁定为 `1051/776` asset 比例，随卡片缩放。Chip 采用 75:8208 的柔和交互 hover 填充与 12px 圆角，并打开 MenuDropdown（figma 122:9481；`--dsw-specific-menu` + `--dsw-shadow-lv3`）：带文件夹图标与尾随勾选的 basename 行，分隔线后是 "New Workspace"，其子菜单（figma 419:16920）提供 "Use a existing folder" 与 "Create new"。Use a existing folder 打开路径 Dialog（figma 451:18655 copy — "Enter an existing folder path" / Open Folder），置于全视口遮罩（`--dsw-alias-bg-mask-1` + `--dsw-mask-blur`）之上，并设置 chip 的 cwd。Create new 打开同一套 Dialog chrome，在 `host.describe().cwd` 下命名文件夹；成功则走 `sessions.createWorkspace` → host `session.create`（mkdir recursive）→ `sessions.open`，在新 workspace 中默认落下一会话。`InputBar` 绘制底栏 chrome（attach / Plan / Read-only / model），仅用本地原生 `<select>` 状态——host 侧的 plan、access、model 接缝仍未接线。

+# Agent Note: Workspace UI Complete Product Flow
+
+Status: implemented
+
+English | [中文](2026-07-25-workspace-ui-product-flow.zh.md)
+
+## Problem
+
+[Domain KV Storage and the Workspace Entity](../../proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md) defines the persistent Workspace entity, path conventions, and ordered Session ledger, but not the Host wiring, historical-data initialization, or GUI flow. The GUI presents both Workspaces and Sessions; users must be able to type immediately after entering New Session, even when no Host Session or Host Workspace exists yet.
+
+Pending Workspaces, pending Sessions, retained input, and Host entity publication need clear owners and must preserve the same page identity when RPC completions and Host frames arrive in either order. Eagerly creating a Host Session for the zero state would bring a page with no input into the Host lifecycle. Historical Sessions also expose only the lightweight `SessionHeader.cwd` for grouping; initialization cannot read event bodies.
+
+## Decision
+
+### Host and persistent data
+
+The Host provides the following GUI wiring on the Workspace entity:
+
+| RPC | Behavior |
+| --- | --- |
+| `workspace.list` | Returns persistent Workspaces in order and filters out Session ids that fail header validation |
+| `workspace.create({ name })` | Creates a directory and Workspace at `workspaceRoot/name`; fails on a display-name conflict |
+| `workspace.create({ path })` | Adopts an existing directory and does not create an arbitrary path |
+| `session.create({ workspaceId, sessionId? })` | Resolves cwd from the Workspace, idempotently creates a Session with an optional preallocated id, and attaches it |
+| `session.create({ cwd })` | Remains available to non-Workspace callers and creates an Ungrouped Session |
+
+`workspaceRoot` is an independent Host setting that falls back to the Host cwd when unset; it is unrelated to `storageRoot`, which stores Workspace domain data. The Host stream pushes Workspace and Session deltas, and the Client refreshes the `workspace.list` and `session.list` baselines separately after reconnecting.
+
+A Workspace's `sessionIds` is an ordered candidate index. A membership projection requires both that an id appear in the index and that the corresponding canonicalized `SessionHeader.cwd` equal the Workspace path; SessionHeader does not gain a `workspaceId`. A Session whose cwd matches but whose id is absent from the index remains Ungrouped, while an indexed id is filtered out if its header is missing, its cwd is invalid, or its cwd does not match. Two Workspace indexes claiming the same Session is corrupt state and fails loudly.
+
+The Workspace domain uses a durable marker to distinguish “never initialized” from “initialized but empty.” When the marker is absent, the Registry calls only `SessionPersistence.list()` to read header metadata; it calls neither `load` nor `inspect`, reads no history, and parses no event bodies. Valid cwd values are grouped by canonical path, and both Sessions within each group and the Workspace groups themselves are initialized in descending header `createdAt` order. Bootstrap is reentrant and writes the marker last; after the marker is written, new Sessions created without `workspaceId` are no longer adopted automatically.
+
+### Client object model
+
+`Session` and `Workspace` are frontend objects from the page Intent stage onward.
+
+- A frontend Session preallocates a SessionId when created and owns its Intent target and `pendingPrompt`; it remains the same Session object after Host `session.create` succeeds.
+- Before materialization, a frontend Workspace has no WorkspaceId and owns its create input, phase, and error; after Host `workspace.create` succeeds, the same Workspace object adopts the returned view.
+- `SessionManager` and `WorkspaceManager` own object indexes and merge Host baselines and deltas; the objects are the sole source of state for both Intents and Host views.
+- `SessionsService` provides Session objects, real selection, scope, and list projections; `WorkspacesService` depends on `SessionsService` and owns the default Workspace, cross-object New Session flow, and Workspace materialization.
+
+A page has at most one frontend Session Intent and one accompanying Workspace Intent that exists only in the zero-Workspace state. Intents exist only on the current page and disappear on refresh; real Session selection can be restored persistently. Selecting a real Session or starting another Session Intent revokes the old Intent's eligibility for automatic sending, but does not roll back a Session already published by the Host or any accepted message.
+
+The Session owns the first input and drives one internal pipeline: when necessary, it attaches to a Workspace with its preallocated id, then sends `pendingPrompt`. Both attach and send failures return to the same Session. Workspace creation phase and error belong only to the Workspace object; the Session does not simulate the Workspace lifecycle.
+
+### User flow
+
+On initial entry, the application waits until both the Workspace and Session baselines are ready. It restores a real Session selection that remains valid; otherwise, it enters New Session and selects the most recent Workspace exactly once. The most recent Workspace is determined by the maximum `updatedAt` of its member Sessions, falling back to `createdAt` for an empty Workspace. This derived value chooses only the default target: it does not alter the Host Workspace order or trigger another selection after later hydration.
+
+When no Workspace exists, the page creates a frontend Workspace object named `workspace` and a frontend Session that targets it. Neither writes to the Host, and the composer always accepts input; the first send materializes the Workspace, attaches the Session, and sends the message in that order.
+
+Top-level New Session, the plus button on a Workspace row, and the Workspace picker all invoke the same New Session action. An explicit Workspace id becomes the target directly; when none is specified, the action uses the most recent Workspace, or the Workspace Intent if no real Workspace exists. The Workspace picker's Use an existing folder and Create a new workspace actions immediately create a real Workspace when the user confirms, then retarget the frontend Session to it; an explicitly created empty Workspace remains even if the user sends no message.
+
+Create a new workspace temporarily uses the same input as both the directory name and display name. The UI prevents duplicate confirmation based on current Workspace titles, while the Host continues to reject same-name requests that bypass the UI or race concurrently. Rename, Delete, moving across Workspaces, drag-and-drop ordering, manual adoption from Ungrouped, and separate display-name and directory-name inputs are outside this iteration's scope.
+
+### First send and recovery
+
+A frontend Session's `pendingPrompt` retains its original text until the Host accepts the message. The first send advances through Workspace materialization, Session attachment, and prompt sending in order:
+
+1. If Workspace creation fails, the Workspace Intent retains its input and error, and the Session continues to target that object.
+2. If Session creation fails before publication, the Session Intent returns to an editable state and retries with the same preallocated SessionId.
+3. `workspace-attach-failed` proves that the Session has been published; the same Session object enters the real list and retains the prompt, and subsequent retries attach it.
+4. If the prompt fails, the Session retains it and retries only send without recreating the Workspace or Session.
+5. If the page switches to another Intent while a Session is being created, the old Session does not send automatically even if it is subsequently published; it retains its original prompt and visible error.
+
+Lost RPC responses, Host frames arriving before completions, and completions arriving before Host frames all converge through the preallocated SessionId and object identity. The Manager performs ordered upserts of Host views and prioritizes preserving the original object identity during local materialization, rather than creating a temporary second row with the same id.
+
+### Sidebar and ordering
+
+Workspace groups strictly follow the persistent order returned by the Host. Bootstrap determines the historical order once, explicitly created Workspaces are placed first, and Session activity does not move Workspace groups.
+
+Within each group, order strictly follows `Workspace.sessionIds`. A newly attached Session is placed first; when a Session later becomes active, the Host moves only that id to the front and persists the change. The Client does not reorder the entire group by time after the Session list arrives, so it never displays one Workspace order and then jumps to another during hydration.
+
+A frontend Session Intent appears as a “New session” row and temporarily counts toward the group's Session total only when it targets a real Workspace. When it targets a Workspace Intent, neither the Workspace nor the Session appears in the sidebar. After the Intent is published, the real row with the same preallocated id takes its place; after refresh, both the Intent row and temporary count disappear. Search mode neither retains nor filters Intent rows.
+
+Real Sessions that cannot be assigned to any Workspace appear under Ungrouped. Host `session-added` and `workspace-changed` events may arrive in either order; list merging does not depend on frame order.
+
+### React and slot boundaries
+
+React components only consume `useSessions`, `useWorkspaces`, and session-scoped hooks; they do not own entity lifecycles. The Zustand store retains only layout, the current view, composer text for ordinary real Sessions, and other purely presentational state. Session and Workspace Intents, materialization phases, errors, and retained prompts reside in the React-free runtime object layer.
+
+The Sidebar and conversation empty hero receive standardized actions through slots: `startSession`, `updateSessionPrompt`, `sendSession`, `open`, and `toggleSidebar`. The Workspace picker reuses the same component and the `createWorkspace` seam; its owner supplies only popover state, an anchor, and a selection callback. The presentation layer does not send `host/workspace-changed` directly; Host events originate only from Host mutations and the stream adapter.

+**Store separate page records for pending Workspaces and Sessions.** This approach must replace identities after materialization and hand off input, errors, focus, and sidebar rows; Intent state owned by the objects preserves identity continuity.
+
+**Let the presentation layer or root Zustand store orchestrate object lifecycles.** This approach duplicates Manager and Service responsibilities and brings domain state back into React. Runtime services provide standardized actions, while slots inject only the narrow interfaces required by presentation.
+
+**Immediately create a Host Session or Host persistence intent in the zero state.** A page with no input would enter the Host lifecycle and change refresh semantics; before the first send, the frontend Session retains only a page-local Intent.
+
+**Delay an explicit Create Workspace until the first send.** After confirmation, the sidebar would still show no real empty Workspace, conflating “create a Workspace” with “prepare a Session”; only the zero-Workspace Intent generated automatically by the system delays materialization.
+
+**Continuously derive Workspaces dynamically from cwd.** This cannot represent empty Workspaces, stable display names, or explicit ordering, and would automatically adopt non-Workspace callers; cwd is used only for one historical bootstrap and bidirectional membership validation.
+
+**Have the Client batch-reorder by time after the Session list arrives.** The initial screen would first show the Host order and then jump as a whole, and reconnecting could change positions again; the Host's persistent ledger owns ordering, while the Client merges only individual updates.
+
+**Add workspaceId to SessionHeader.** This would create two persistent ownership fields alongside the Workspace index and require double writes; the header retains the Session's own cwd fact, while the Workspace index owns explicit membership.
+
+## Verification
+
+- The zero state with no Workspace writes nothing to the Host and accepts input; explicit Create Workspace immediately creates and displays an empty Workspace.
+- Frontend Sessions and Workspaces preserve object identity across materialization; input, errors, focus, and sidebar projections always originate from the object layer.
+- The first send advances through Workspace, Session, and prompt in order; successful stages are not rolled back, input is not lost before the prompt is accepted, and creation retries use the same SessionId.
+- Workspace list performs one reentrant bootstrap using only headers; an initialized empty registry does not initialize again after restart, and membership reads validate both the index and canonical cwd.
+- The initial default target is determined exactly once after both baselines are ready; Workspace groups are not reordered as a whole by hydration or Session activity, and an active Session moves only itself to the front.
+- A frontend Session under a real Workspace temporarily counts toward the sidebar total, while a Workspace Intent remains hidden; neither publication nor refresh leaves duplicate rows or counts.
+- Both the UI and Host reject duplicate Workspace names; cwd-only Sessions, Sessions with invalid historical cwd values, and unattached Sessions remain Ungrouped.
+- Keyless runnable snapshots cover the zero state, explicit creation, and the first send; package-level tests cover bootstrap, membership validation, ordering, idempotency, failure recovery, and arbitrary frame order.
+
+## Consequences
+
+- SessionHeader does not record last-active time, so historical bootstrap can initialize order only by `createdAt`; real Session activity events move individual entries afterward.
+- Historical Sessions with a missing cwd, an invalid directory, or a failed realpath remain Ungrouped; this iteration has no manual-adoption entry point.
+- Refreshing the page discards unmaterialized Workspace and Session Intents and input not yet accepted by the Host; this is the page-local contract.
+- Explicit Create Workspace writes to disk immediately, so leaving without sending still leaves an empty Workspace.
+- Before its first event, a Host Session retains the existing lazy-persistence semantics; frontend Intents do not change empty-Session behavior after a Host restart.

+# Agent Note: Workspace UI 完整产品动线
+
+[English](2026-07-25-workspace-ui-product-flow.md) | 中文
+
+Status: implemented
+
+## Problem
+
+[Domain KV storage 与 Workspace entity](../../proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md)定义了 Workspace 的持久实体、路径规范和有序 Session 账本，但没有定义 Host 接线、历史数据初始化或 GUI 动线。GUI 同时呈现 Workspace 和 Session；用户进入 New Session 后必须立即输入，即使此时还没有 Host Session，甚至没有 Host Workspace。
+
+待创建 Workspace、待创建 Session、输入保留与 Host 实体发布必须具有明确所有者，并在 RPC completion 与 Host frame 以任意顺序到达时保持同一页面身份。若零态提前创建 Host Session，则无输入的页面状态会进入 Host 生命周期。历史 Session 又只有轻量 `SessionHeader.cwd` 可用于归组，初始化不能读取事件正文。
+
+## Decision
+
+### Host 与持久数据
+
+Host 在 Workspace entity 上提供以下 GUI 接线：
+
+| RPC | 行为 |
+| --- | --- |
+| `workspace.list` | 返回持久有序的 Workspace，并过滤未通过 header 校验的 Session id |
+| `workspace.create({ name })` | 在 `workspaceRoot/name` 创建目录和 Workspace；显示名冲突时失败 |
+| `workspace.create({ path })` | 收编已经存在的目录，不为任意路径创建目录 |
+| `session.create({ workspaceId, sessionId? })` | 从 Workspace 解析 cwd，以可选预分配 id 幂等创建 Session 并 attach |
+| `session.create({ cwd })` | 保留给非 Workspace 调用方，创建 Ungrouped Session |
+
+`workspaceRoot` 是独立 Host 配置，未配置时回退到 Host cwd；它与保存 Workspace domain 数据的 `storageRoot` 无关。Host stream 推送 Workspace 与 Session 增量，Client 重连后分别刷新 `workspace.list` 与 `session.list` 基线。
+
+Workspace 的 `sessionIds` 是有序候选索引。成员投影同时要求 id 位于索引且对应 `SessionHeader.cwd` canonical 后等于 Workspace path；SessionHeader 不增加 `workspaceId`。cwd 匹配但未入索引的 Session 保持 Ungrouped，索引命中但 header 缺失、cwd 无效或 cwd 不匹配的 id 被过滤。同一 Session 被两个 Workspace 索引占用属于损坏状态并 fail loud。
+
+Workspace domain 以 durable marker 区分“从未初始化”和“已初始化但为空”。marker 未设置时，Registry 只调用 `SessionPersistence.list()` 读取 header 元数据，不调用 `load`、`inspect`、history 或解析事件正文；有效 cwd 按 canonical path 分组，组内 Session 与 Workspace 组均按 header `createdAt` 降序初始化。Bootstrap 可重入，最后才写 marker；marker 写入后，绕过 `workspaceId` 的新 Session 不再被自动收编。
+
+### Client 对象模型
+
+`Session` 与 `Workspace` 从页面 Intent 阶段开始就是前端对象。
+
+- 前端 Session 创建时预分配 SessionId，并在对象内持有 Intent target 与 `pendingPrompt`；Host `session.create` 成功后仍是同一个 Session 对象。
+- 前端 Workspace 在 materialize 前没有 WorkspaceId，并在对象内持有 create input、phase 与 error；Host `workspace.create` 成功后同一个 Workspace 对象 adopt 返回的 view。
+- `SessionManager` 与 `WorkspaceManager` 负责对象索引、Host 基线和增量合并；对象是 Intent 与 Host view 的唯一状态源。
+- `SessionsService` 提供 Session 对象、真实 selection、scope 与列表投影；`WorkspacesService` 依赖 `SessionsService`，负责默认 Workspace、跨对象 New Session 动线和 Workspace materialize。
+
+页面至多有一个前端 Session Intent 和一个仅在零 Workspace 状态下配套的 Workspace Intent。Intent 只存在于当前页面，刷新后消失；真实 Session selection 可以持久恢复。选择真实 Session 或启动另一个 Session Intent 会放弃旧 Intent 的自动发送资格，但已经由 Host 发布的 Session 和已经接受的消息不会回滚。
+
+Session 自己持有首条输入并驱动一条内部流水线：必要时以预分配 id attach 到 Workspace，然后发送 `pendingPrompt`。attach 与 send 的失败都落回同一 Session。Workspace 创建 phase/error 只属于 Workspace 对象，Session 不模拟 Workspace 生命周期。
+
+### 用户动线
+
+应用首次进入时等待 Workspace 与 Session 两份基线 ready。仍有效的真实 Session selection 被恢复；否则进入 New Session，并固定选择一次最近 Workspace。最近 Workspace 取其成员 Session 的最大 `updatedAt`，空 Workspace 回退到 `createdAt`；该派生只决定默认目标，不改变 Host Workspace 顺序，也不会在后续 hydration 时二次改选。
+
+完全没有 Workspace 时，页面创建默认名为 `workspace` 的前端 Workspace 对象和指向它的前端 Session。两者不写 Host，composer 始终可输入；首次发送才依次 materialize Workspace、attach Session、发送消息。
+
+顶部 New Session、Workspace 行内加号和 Workspace picker 最终都调用同一 New Session 动作：显式 Workspace id 直接成为目标，未指定时使用最近 Workspace，没有真实 Workspace 时使用 Workspace Intent。Workspace picker 的 Use an existing folder 与 Create a new workspace 会在用户确认时立即创建真实 Workspace，再把前端 Session 定位到该 Workspace；即使用户不发送消息，显式创建的空 Workspace 也保留。
+
+Create a new workspace 暂时用同一个输入作为目录名和显示名。UI 根据当前 Workspace title 禁止重复确认，Host 继续拒绝绕过 UI 或并发产生的同名请求。Rename、Delete、跨 Workspace 移动、拖拽排序、Ungrouped 手动收编和显示名/目录名双输入不在本期范围。
+
+### 首次发送与恢复
+
+前端 Session 的 `pendingPrompt` 在 Host 接受消息前始终保留原文。首次发送按 Workspace materialize、Session attach、prompt send 顺序推进：
+
+1. Workspace 创建失败时，Workspace Intent 保留输入与错误，Session 仍指向该对象。
+2. Session 创建在发布前失败时，Session Intent 回到可编辑状态，以同一预分配 SessionId 重试。
+3. `workspace-attach-failed` 证明 Session 已发布；同一 Session 对象进入真实列表并保留 prompt，后续重试 attach。
+4. prompt 失败时，Session 保留 prompt 并只重试 send，不重复创建 Workspace 或 Session。
+5. Session 创建期间若页面切换到另一个 Intent，旧 Session 即使随后发布也不自动发送；它保留原 prompt 和可见错误。
+
+RPC lost response、Host frame 先于 completion 和 completion 先于 Host frame 都通过预分配 SessionId 与对象身份收敛。Manager 对 Host view 做有序 upsert，本地 materialize 时优先保留原对象身份，不生成同 id 的临时第二行。
+
+### Sidebar 与排序
+
+Workspace 组严格使用 Host 返回的持久顺序。Bootstrap 一次性确定历史顺序，显式创建的新 Workspace 放在首位；Session 活跃不会移动 Workspace 组。
+
+组内严格使用 `Workspace.sessionIds`。新 attach 的 Session 放在首位，后续某个 Session 活跃时 Host 只前移该 id 并持久化。Client 不在 Session list 到达后按时间整体重排，因此不会先显示一套 Workspace 顺序再因 hydration 瞬间跳动。
+
+前端 Session Intent 只有在目标是真实 Workspace 时才作为 “New session” 行显示，并临时计入该组 Session 数量；目标是 Workspace Intent 时，Workspace 与 Session 都不进入 sidebar。Intent 发布后由同一预分配 id 对应的真实行接替，刷新后 Intent 行和临时计数一起消失。搜索模式不保存或筛选 Intent 行。
+
+无法归入任何 Workspace 的真实 Session 进入 Ungrouped。Host `session-added` 与 `workspace-changed` 可以任意顺序到达，列表合并不依赖 frame 顺序。
+
+### React 与 slot 边界
+
+React 组件只消费 `useSessions`、`useWorkspaces` 与 session-scoped hooks，不拥有实体生命周期。Zustand store 只保留布局、当前 view、普通真实 Session 的 composer 文本和其他纯呈现状态；Session/Workspace Intent、materialize phase、错误和 retained prompt 位于 React-free runtime 对象层。
+
+Sidebar 与 conversation empty hero 通过 slot 获得标准化动作：`startSession`、`updateSessionPrompt`、`sendSession`、`open` 与 `toggleSidebar`。Workspace picker 复用同一组件与 `createWorkspace` seam；owner 只提供 popover 开关、锚点和选中回调。呈现层不直接发送 `host/workspace-changed`，Host event 只由 Host mutation 与 stream adapter 产生。
+
+## Alternatives considered
+
+**为待创建 Workspace 与 Session 保存独立页面记录。** 该方案在 materialize 后需要替换身份并转交输入、错误、焦点和 sidebar 行；对象自身的 Intent 状态可以保持身份连续。
+
+**由呈现层或 root Zustand store 编排对象生命周期。** 该方案会重复 Manager/Service 的职责，并把领域状态带回 React。标准化动作由 runtime service 提供，slot 只注入呈现所需的窄接口。
+
+**零态立即创建 Host Session 或 Host persistence intent。** 未输入页面会进入 Host 生命周期，并改变刷新语义；前端 Session 在首次发送前只保留 page-local Intent。
+
+**显式 Create Workspace 延迟到首次发送。** 用户确认后 sidebar 仍看不到真实空 Workspace，“创建 Workspace”与“准备 Session”语义混合；只有系统自动产生的零 Workspace Intent 延迟 materialize。
+
+**持续按 cwd 动态派生 Workspace。** 该方案无法表达空 Workspace、稳定显示名和显式顺序，也会自动收编非 Workspace 调用方；cwd 只用于一次历史 bootstrap 与成员双向校验。
+
+**Client 在 Session list 到达后按时间批量重排。** 首屏会先展示 Host 顺序再整体跳动，重连也可能改变位置；排序由 Host 持久账本拥有，Client 只合并单项更新。
+
+**在 SessionHeader 增加 workspaceId。** 它会与 Workspace 索引形成两个持久归属字段并要求双写；header 保留 Session 自身 cwd 事实，Workspace 索引负责显式归属。
+
+## Verification
+
+- 完全无 Workspace 的零态不写 Host 且允许输入；显式 Create Workspace 立即创建并显示空 Workspace。
+- 前端 Session 与 Workspace 在 materialize 前后保持对象身份，输入、错误、焦点和 sidebar 投影始终来自对象层。
+- 首发按 Workspace、Session、prompt 顺序推进，各成功阶段不回滚，输入在 prompt 接受前不丢失，创建重试使用同一 SessionId。
+- Workspace list 只读取 header 完成一次可重入 bootstrap；initialized 的空 registry 重启不重复初始化，成员读取同时校验索引与 canonical cwd。
+- 初始默认目标只在两份基线 ready 后确定一次；Workspace 组不因 hydration 或 Session 活跃整体重排，单个活跃 Session 只前移自身。
+- 真实 Workspace 下的前端 Session 临时计入 sidebar 数量，Workspace Intent 保持隐藏，发布与刷新都不会留下重复行或重复计数。
+- UI 与 Host 两层拒绝同名 Workspace；cwd-only Session、无效历史 cwd 和未 attach Session 保持 Ungrouped。
+- keyless runnable snapshot 覆盖零态、显式创建和首次发送；包级测试覆盖 bootstrap、成员校验、排序、幂等、失败恢复及任意 frame 顺序。
+
+## Consequences
+
+- SessionHeader 不记录最后活跃时间，历史 bootstrap 只能按 `createdAt` 初始化；此后由真实 Session 活跃事件逐项前移。
+- 历史 cwd 缺失、目录无效或 realpath 失败的 Session 留在 Ungrouped；本期没有手动收编入口。
+- 页面刷新会丢弃未 materialize 的 Workspace/Session Intent 和尚未被 Host 接受的输入，这是 page-local 契约。
+- 显式 Create Workspace 立即落盘，用户不发送就离开也会留下空 Workspace。
+- Host Session 在首个事件前仍遵循现有懒持久化语义；前端 Intent 不改变 Host 重启后的空 Session 行为。

## Problem
AGENTS.md promises that docs and code stay strictly in sync, but the promise was verified by eyeball. Review caught drift twice — a cookbook example contradicting the type policy, and a README citing the wrong `registerAdapter` call. Out-of-sync docs are worse than no docs, and this codebase is built primarily by agents that follow gates far more reliably than prose (mechanical quality gates). Two classes of doc drift are mechanically checkable: code blocks that no longer compile, and the event-taxonomy table that duplicates the `interface Events` declarations.

+# Agent Note: Doc-sync 强制
+
+Status: implemented
+
+[English](2026-06-11-doc-sync-enforcement.md) | 中文
+
+## 问题
+
+AGENTS.md 承诺文档与代码严格同步，但这一承诺此前仅靠人眼核查。评审曾两次发现漂移：一次是实操手册（cookbook）示例与类型策略矛盾，一次是 README 引用了错误的 `registerAdapter` 调用。失去同步的文档比没有文档更糟；而本代码库主要由 agent（智能体）构建，agent 遵守门禁远比遵守行文约定可靠（机械质量门禁）。有两类文档漂移可以被机械检查：不再能编译的代码块，以及与 `interface Events` 声明重复的事件分类体系表。
+
+## 决策
+
+两道门禁，沿用既有的 `scripts/` 风格（tsx ESM，每个脚本一项职责）：
+
+1. **`doc-typecheck`** 从 `README.md`、`docs/**` 和 `packages/*/README.md` 中提取所有 ` ```ts ` 围栏代码块，写入一个继承根 `tsconfig.json` 的临时项目，然后用 `tsc -b` 编译。临时项目复用源码的 `paths` 映射和根 project references，因此文档示例能看到源码，而 vendor 代码仍在其自身的 tsconfig 设置下被检查。刻意作为草图的代码块可通过显式的 ` ```ts ignore-check ` 信息字符串来 opt-out；脚本会报告 opt-out 比例，超过一半即失败，防止该豁免机制悄然成为常态。
+2. **`verify-event-taxonomy`** 从 `packages/*/src` 中的 `interface Events` 块和 `docs/architecture.md` 中的分类体系表分别提取事件名称，断言两个集合完全一致。只校验，不生成：表格保留手写的 Mode/Purpose 列，仅检查名称集合。（落地此门禁时发现了表格遗漏的三个事件：`tools/change`、`llm/adapter-change`、`system-prompt/change`。）**已被取代**：由[生成式 Cordis 目录](2026-06-20-generated-cordis-catalog.md)取代。此门禁及其 `architecture.md` 表格已退役，取而代之的是完全生成的 `docs/cordis-catalog/events.md` + `docs/cordis-catalog/services.md` 及其 `verify-cordis-catalog` 新鲜度门禁。本 Agent Note（agent 决策记录）中的其他门禁（`doc-typecheck` 以及下文修订中的 `verify-md-wrap`）不受影响。
+
+两者都通过 package.json 中共享的 `doc-sync` 脚本运行；贡献者在相关文档变更中调用它，CI 则执行完整检查。[快速本地 Git 钩子](2026-07-22-fast-local-git-hooks.md)决策使这类按变更面选择的工作不进入 commit 和 push 钩子。
+
+**修订（2026-06-17）：** 第三道门禁 **`verify-md-wrap`** 随后被纳入 `doc-sync`。它使用 `mdast-util-from-markdown` + GFM 解析范围内的每个 Markdown 文件（`README.md`、`docs/**`、`packages/*/README.md`，加上 `AGENTS.md` / `packages/AGENTS.md`），如果任何 `paragraph` 节点跨越多个源码行则失败，从而强制执行 docs/AGENTS.md 中「一个段落一个物理行」的写作规则。同样遵循只校验不生成的原则：它报告硬换行但从不重写，因此不会引入格式化噪音。`doc-sync` 现在包含三道门禁。
+
+## 曾考虑的替代方案
+
+- **API-extractor 基准报告**（[已推迟的提案](../../proposed/process/2026-06-11-api-extractor-reports.md)）：有意推迟。对于评审者已能直接看到源码 diff 的内部 monorepo 而言价值有限，且依赖重、配置繁琐。
+- **从源码生成分类体系表**而非仅校验名称：否决，机制比问题本身更重；表格保留了手写的 Mode/Purpose 列，直到[生成式 Cordis 目录](2026-06-20-generated-cordis-catalog.md)完全取代了这项检查。
+
+## 后果
+
+- 可检查类别中的文档漂移会直接使 `doc-sync` 和 CI 失败，而不是等评审人发现。这是「机械门禁优于行文规范」原则的具体应用。
+- 让文档代码片段可编译需要少量 stub import/`declare`；`ignore-check` 比例必须保持低位，否则门禁形同虚设（比例守卫强制执行此约束）。
+- 分类体系检查仅限名称——Mode 或 Purpose 列的错误仍需人工评审。
+- 如果包（package）未来对外发布，API 报告方案仍可重新考虑。

+# Agent Note: 以机械质量门禁取代行文约定
+
+Status: implemented
+
+[English](2026-06-11-quality-gates.md) | 中文
+
+本记录中的钩子/CI 对称设计已由[快速本地 Git 钩子](2026-07-22-fast-local-git-hooks.md)取代；CI 仍是执行完整检查的路径。
+
+## 问题
+
+本代码库主要由 coding agent（智能体）开发。相比行文约定，agent 遵守强制门禁的可靠性远高得多；而当劳动由 agent 承担时，「工作量大」不构成成本论据。早期证据：未通过类型检查的测试被提交（vitest 不做类型检查），仅在评审中才被发现。
+
+## 决策
+
+每条可机械检查的 AGENTS.md 承诺都有一个以非零状态退出的命令。CI 执行完整集合，而 Git 钩子将延迟预算留给可低成本发现的本地缺陷：
+
+- 最严格的 TypeScript 配置（`noUncheckedIndexedAccess`、`exactOptionalPropertyTypes` 等）；示例、测试和脚本通过根目录的 no-emit `tsconfig.json` 在 CI 中进行类型检查，而包（package）/vendor 代码保持在各自 project-reference 边界之后。
+- ESLint strict-type-checked + @stylistic（作为强制执行的统一代码风格），包括文件内重复逻辑检查；vendor 代码排除在外。
+- jscpd 检测包的生产 TypeScript 代码与仓库脚本中的跨文件克隆；窄范围的源码区间例外用于记录有意为之的并行实现。
+- `packages/*/*/src` 下按文件 100% 覆盖率（v8）；不可达的防御性守卫使用 `/* v8 ignore */ ` 并注明理由，而非删除。
+- knip（死代码/依赖）、publint（包的正确性）、workspace 约束（workspace 规则：private、cordis peer+dev、统一版本、ESM），以及对构建出的包声明文件进行 NodeNext 消费方类型检查。
+- lefthook pre-commit 修复已暂存文件的 lint 问题、拒绝已暂存的空白问题并检查 vendor manifest；pre-push 运行增量类型检查。CI 在 Node 22.19/24/26 上运行完整矩阵，并对 Headless、TUI、ACP（Agent Client Protocol）、JSON-RPC、工作流和代码运行时入口路径执行已构建应用的冒烟测试。
+
+## 后果
+
+- 约定不会因 agent 更替而失效；可低成本发现的 commit/push 缺陷在本地失败，其余完整规则违规在 CI 中失败。
+- 门禁本身也是需要维护的代码；配置变更与其他变更一样需要评审。
+- 100% 覆盖率的压力可能催生无断言的测试——变异测试是计划中的对策（见[变异测试提案](../../proposed/testing/2026-06-11-mutation-testing.md)）。

## Problem
The initial build used **dumble**, the cordiverse zero-config esbuild wrapper that upstream Cordis itself builds with — maximum alignment with the vendored packages' conventions (it reads each package.json and infers entries/formats from the `exports` field). But dumble is a liability as a load-bearing tool in this repo: v0.2.x, ~530 npm downloads/week, effectively one maintainer, and we were invoking it through a custom orchestration script (`scripts/build.ts`) because it has no workspace mode.

+# Agent Note: 使用 tsdown 替代 dumble 进行 JS 打包
+
+Status: implemented
+
+[English](2026-06-11-tsdown-over-dumble.md) | 中文
+
+## 问题
+
+最初的构建使用 **dumble**，即 cordiverse 的零配置 esbuild 包装层——上游 Cordis 自身也用它构建——与 vendor 包（package）的约定最大程度对齐（它读取每个 package.json 并从 `exports` 字段推断入口/格式）。但 dumble 作为本仓库的承重工具存在隐患：v0.2.x，每周约 530 次 npm 下载，实质上只有一位维护者，而且由于它没有 workspace 模式，我们不得不通过自定义编排脚本（`scripts/build.ts`）来调用它。
+
+目前构建产物只在 `pnpm run build` + publint 中有意义（尚未发布任何包；开发/测试/演示通过 tsx 直接运行未打包的源码），因此切换成本现在最低，一旦包开始发布就只会更高。
+
+## 决策
+
+用 **tsdown**（基于 rolldown，每周约 250 万次下载，VoidZero 支持，活跃发布）替代 dumble：
+
+- 根目录 `tsdown.config.ts`，配置 `workspace: ['vendor/*', 'packages/*/*']`（显式 glob 将打包范围限定在 vendor 的 Cordis 与 TypeScript 包目录树内；`workspace: true` 还会发现示例 manifest 和不需要打包的 workspace 成员）。
+- 共享形状：入口为 `lib/types/index.js`，`outDir: 'lib'`，ESM，`platform: node`，`target: es2024`，`fixedExtension: false`（为 `"type": "module"` 包保留 `.js`），`dts: false`（声明归 tsc -b 所有），`clean: false`（lib/ 还保存 TSC 的 `lib/types` 中间树）。入口最初是 `src/index.ts`；[TSC 优先构建 Agent Note（agent 决策记录）](2026-06-17-ts-build-config.md)随后将 tsdown 改为打包 TSC 输出的 JS，使 TypeScript 转换行为统一由一个编译器提供。
+- vendor/ 中有两个按包覆盖的配置（属于我们自己的修改，与重新生成的 tsconfig 类似；记录在 vendor/README.md 中）：schemastery（通过 `outExtensions` 输出双格式 `.mjs`/`.cjs`）、logger-console（两次单入口 pass，使共享基类被内联到每个入口而非生成哈希命名的分片，与上游发布形态一致）。
+- `scripts/build.ts` 删除；`pnpm run build` = `tsc -b && tsdown`（根 solution 拥有 emit 图）。
+
+## 曾考虑的替代方案
+
+- **直接编写 esbuild 脚本**：最成熟的引擎，零包装层风险，但需要手动维护 tsdown workspace 模式自动提供的按包规格表。
+- **pkgroll**：理念上最接近的直接替代品，但每周仅 78k 下载且基于 Rollup，维护前景严格弱于 tsdown。
+- **保留 dumble**：与上游完美对齐，但巴士因子不可接受。
+
+## 后果
+
+运行时 bundle 输出仍沿用 dumble 时代的公开入口形状（`lib/index.js`，以及包特有的变体，例如 `schemastery` 的 `lib/index.mjs`/`lib/index.cjs` 与 `logger-console` 的 `lib/browser.js`）；根据 [TSC 优先构建 Agent Note](2026-06-17-ts-build-config.md)，声明现位于 `lib/types` 下。External 仍来自各包的 dependencies/peerDependencies。我们放弃了 dumble 的 exports 字段推断：采用非默认形状的新包需要逐包提供 `tsdown.config.ts`，不能只依赖 package.json 字段。未来如果 `tsc -b` 成为瓶颈，tsdown 也可以接管声明打包（isolatedDeclarations）；这需要另写一份 Agent Note。

## Problem
DeepSeek Harness SDK is built on the Cordis framework. Cordis core was at 4.0.0-rc.6 (a release candidate) when this repo started; the harness depends on framework internals (fiber lifecycle, effect disposal, waterfall dispatch) whose exact behavior matters to the agent loop's correctness guarantees.

+# Agent Note: 将 Cordis 以源码形式收录，而非作为 npm 依赖
+
+Status: implemented
+
+[English](2026-06-11-vendor-cordis-as-source.md) | 中文
+
+## 问题
+
+DeepSeek Harness SDK 构建于 Cordis 框架之上。本仓库启动时，Cordis core 处于 4.0.0-rc.6（一个候选发布版本）；harness 依赖框架内部实现（fiber 生命周期、dispose（资源释放）、waterfall（瀑布式事件）分发），其确切行为直接关系到 agent loop（智能体循环）的正确性保证。
+
+## 决策
+
+将所需的 Cordis 包（core、loader、include、group、timer、hmr、logger-console）与 cordiverse 基础库（cosmokit、schemastery）以源码形式复制到 `vendor/`，扁平化放置，保留其原始 npm 包名以实现透明的 workspace 解析。真正的第三方依赖（js-yaml、chokidar、@standard-schema/spec 等）仍从 npm 获取。
+
+`vendor/README.md` 是 manifest（元数据清单）：记录每个包（package）的上游仓库 + commit SHA，以及一份详尽的本地修改日志。pre-commit 守卫（`scripts/check-vendor-manifest.sh`）会拒绝未在同一次提交中更新 manifest 的 vendor 源码变更。
+
+## 曾考虑的替代方案
+
+- **依赖 npm 包**：否决。core 处于候选发布阶段，harness 依赖框架内部实现（fiber 生命周期、dispose、waterfall 分发），agent loop 的正确性保证取决于这些行为的确切表现；上游 RC 版本升级可能在没有本地修复路径的情况下破坏它们。
+- **递归收录所有传递依赖**：否决。真正的第三方依赖（js-yaml、chokidar、@standard-schema/spec 等）仍从 npm 获取；只有内部实现对我们有影响的框架层才需要自行持有。
+
+## 后果
+
+- harness 完全持有其框架层：可审计、可打补丁、版本锁定。上游 RC 无法影响我们，框架 bug 可以在仓库内直接修复。
+- 上游同步是手动操作（流程记录在 manifest 中）。修改日志使 diff 范围始终可知。
+- 收录的包保留上游代码风格；lint 与严格性门禁将其排除（它们的 tsconfig 在本地放宽了我们较新的编译器选项）。
+- 从第一天起就有一个本地补丁：移除了 hmr 的 locale-YAML 导入（运行时 YAML 导入钩子未被收录）。

## Problem
The repo shipped on **Yarn 4** with the `node-modules` linker — a deliberately conservative choice that behaves like npm's flat layout while giving us Yarn's workspaces and `yarn constraints`. It worked. But Yarn 4's Plug'n'Play heritage makes the `node-modules` linker the off-the-beaten-path mode, and the broader JS ecosystem — tooling defaults, CI actions, Corepack examples, contributor familiarity — increasingly centers on pnpm. For a repo that is built primarily by agents and read by occasional human contributors, "the package manager most tools and people expect" has real value: fewer surprises, better-trodden failure paths, more copy-pasteable answers.

+# Agent Note: 使用 pnpm 替代 Yarn 4 作为包管理器
+
+Status: implemented
+
+[English](2026-06-16-pnpm-over-yarn.md) | 中文
+
+## 问题
+
+本仓库最初使用 **Yarn 4** 搭配 `node-modules` 链接器启动。这是一个刻意保守的选择：行为类似 npm 的扁平布局，同时享有 Yarn 的 workspaces 和 `yarn constraints`。它能正常工作。但 Yarn 4 源自 Plug'n'Play 的血统，使得 `node-modules` 链接器成为非主流模式；而更广泛的 JS 生态——工具默认值、CI action、Corepack 示例、贡献者的熟悉度——正日益以 pnpm 为中心。对于一个主要由 agent（智能体）构建、偶尔有人类贡献者阅读的仓库而言，「大多数工具和人所期望的包管理器」具有实际价值：更少的意外、更成熟的故障路径、更多可直接复用的解答。
+
+切换成本目前处于最低点。本仓库尚无任何包（package）发布（每个包都是 `private: true`）；开发/测试/演示全部通过 tsx **未构建**运行，因此包管理器只需做到：（a）解析并链接 `node_modules`，（b）运行 workspace 脚本，（c）强制执行 workspace 约束。唯一的 Yarn 特有资产是 `yarn.config.cjs`（`@yarnpkg/types` 约束引擎），体量小且可机械地重新表达。这与 [tsdown 决策](2026-06-11-tsdown-over-dumble.md)的逻辑一致：在爆炸半径尚小时，将承重工具换为生态更健康的选项。
+
+## 决策
+
+采用 **pnpm 11.7.0**，通过 `packageManager` 字段固定版本，经 Corepack 安装（与 Yarn 使用的机制相同）：
+
+- **Workspaces** 从 `package.json` 的 `workspaces` 数组 + `.yarnrc.yml` 迁移到 `pnpm-workspace.yaml`（`vendor/*`、`packages/*`——同样的 glob；`examples/*` 保持非 workspace，与先前设置及 tsdown 的显式 glob 一致）。
+- **严格符号链接链接器**（pnpm 默认）取代 Yarn 的提升式 `node-modules` 链接器。我们刻意**不**添加 `node-linker=hoisted` / `shamefully-hoist` 逃生口：pnpm 的非扁平 `node_modules` 会让幻影依赖（引用未声明的传递依赖）大声失败，这对于一个以机械门禁为核心质量保障的仓库（见[机械质量门禁](2026-06-11-quality-gates.md)）是一项*优势*。门禁套件（类型检查、lint、test、build、knip）是证明不存在此类幻影导入的安全网。
+- **构建脚本白名单。** pnpm 10+ 不运行依赖的生命周期脚本，除非将其加入白名单。`pnpm-workspace.yaml` 携带一份显式的 `allowBuilds` 映射（`esbuild`、`lefthook`、`@google/genai`、`protobufjs`）——与本仓库对模型/工具输出已有的供应链加固姿态一致，现在也应用于安装时的代码执行。`peerDependencyRules.allowedVersions.typescript: '>=5 <7'` 消除仓库内 TypeScript 的良性 peer 范围警告。
+- **约束变为包管理器无关。** `yarn.config.cjs`（导入 `@yarnpkg/types`，使用 `Yarn.workspaces()` / `workspace.set()`）被 `scripts/check-workspace-constraints.ts` 取代——一个纯 tsx 脚本，通过 `pnpm run constraints` 运行。它在相同的 `vendor` + `packages` 范围上强制执行完全相同的不变式：每个包 `private: true`；`@deepseek-ai/dsh-*` 包将 `cordis` 同时声明为对等依赖（peer dependency）和 dev 依赖且范围一致、使用根 `package.json` 的版本、设置 `type: module`；vendor 包仅检查 privacy。
+- 所有 CI、lefthook 钩子、`package.json` 脚本和文档中的 `yarn …` 动词变为 `pnpm …` / `pnpm run …`。`yarn.lock` → `pnpm-lock.yaml`（lockfile v9）。`.gitignore` 将 `.yarn/` 换为 `.pnpm-store/`。vendor README（如 `vendor/cordis/README.md`）按 Vendoring Policy 保持其上游 `yarn` 示例不变。
+
+## 曾考虑的替代方案
+
+- **保留 Yarn 4**——零变动，但押注于使用率较低的链接器模式和一个绑定单一包管理器的约束引擎。
+- **npm workspaces**——无处不在，但没有约束方案，monorepo 开发体验也较差。
+- **pnpm 搭配提升式链接器**——迁移更平滑，但放弃了幻影依赖安全性，而这正是迁移的核心正确性理由。
+
+## 后果
+
+约束检查失去了 Yarn 的自动**修复**能力（`workspace.set()` 能原地改写 manifest）；tsx 脚本仅做检查，不通过时以非零退出码和消息退出。这是可接受的：CI 从未运行过 `--fix`，且需要手动编辑的情况很少。贡献者现在为 pnpm 而非 Yarn 运行 `corepack enable`；`pnpm exec lefthook install` 取代 `yarn lefthook install`（`postinstall` 钩子仍会运行 `lefthook install`）。
+
+性能（迁移时在开发 NFS 文件系统上测量；单次运行样本，方差大——仅供方向性参考，非基准测试套件）：
+
+| 场景 | Yarn 4 | pnpm 11 |
+|---|---|---|
+| 冷启动（空缓存/store，无 `node_modules`） | ~14 s | ~16 s |
+| 热重链接（缓存/store 已热，`node_modules` 已删除） | ~12–14 s | ~15–22 s |
+| 冻结，`node_modules` 存在（无操作重验证） | ~2–8 s | ~0.5–7 s |
+
+在快速本地磁盘上，pnpm 的内容寻址 store 通常在冷/热安装中胜出，尤其在多个检出之间的**磁盘占用**方面优势明显（一个全局 store 通过硬链接接入每个 `node_modules`，而 Yarn 每个 worktree 复制约 279 MB——部分开发者经常为本仓库保持约 10 个或更多 worktree）。该去重优势在上述迁移时数据中**未能**体现，因为测试 store 和 `node_modules` 位于不同文件系统，硬链接失效；在单文件系统的开发机或 CI 缓存上则适用。诚实的总结：在我们的 NFS 开发文件系统上，安装速度在噪声范围内不分伯仲；迁移的理由是生态对齐、幻影依赖安全性和跨检出磁盘去重，而非原始安装时间的胜出。
+
+所有质量门禁（constraints、类型检查、lint、doc-sync、达到 100% 的 test:coverage、构建、knip、publint 以及已构建应用的冒烟测试）均在 pnpm 下通过，证明更换 linker 没有引入幽灵依赖故障。

+# Agent Note: TSC 优先构建与编译器单一归属
+
+Status: implemented
+
+[English](2026-06-17-ts-build-config.md) | 中文
+
+> 根项目拓扑（即哪个 tsconfig 拥有哪张图）后来改为由一个 solution 根文件统辖两个聚合 program；见[solution 根文件 Agent Note](2026-07-22-tsconfig-solution-root-two-aggregates.md)。本文确定的 TSC 优先流水线保持不变。
+
+## 问题
+
+此前的 TypeScript 构建与类型检查配置存在以下问题：
+
+- `build` 使用 `tsc` 将 `packages/<group>/<pkg>` 和 `vendor/*` 下的 `.ts` 转换为 `.d.ts` 文件，然后使用 `tsdown` 将 `.ts` 转换为打包后的 `.js` 文件。这导致两个工具各自执行 TypeScript 转换。
+- `typecheck` 倾向于通过一个根目录的类型检查配置来校验包（package）、vendor 源码、示例、测试和脚本。
+
+目标是让构建与类型检查使用一致的 tsconfig 边界和 TypeScript 解析/转换行为。构建应通过单一编译器和配置生成 `.js`、`.d.ts`、`.js.map` 和 `.d.ts.map`，使发布产物与类型校验保持一致。
+
+验证过程中发现了若干具体的技术问题和可能的路径：
+
+- `tsdown` 使用 `oxc` 进行 TypeScript 转换，其行为与 `tsc` 不同。
+ - `tsdown` 输出的打包 `.d.ts` 与 Cordis 内部的相对模块增强（module augmentation）结构冲突。
+ - tsc 的输出受 `allowImportingTsExtensions` 影响，因此需要确保生成的 `.js` 文件不会导入 `.ts` 文件，且生成的 `.d.ts` 文件保留 NodeNext/Node16 接受的显式相对说明符。为此，包内相对导入在 TypeScript 源码中使用显式 `.ts` 说明符，由 `rewriteRelativeImportExtensions` 在输出的 JS 中将其重写为 `.js`。
+ - `tsdown` 输出的打包 `.js` 与 `tsc -b` 逐文件输出的 `.js` 行为不同，例如装饰器转换行为。
+- `vendor/*/src`、示例、测试和脚本无法全部以 plain-include 方式纳入一个根目录的严格程序。
+ - 在根目录严格配置下直接对 `vendor/*/src` 做类型检查，会触发大量不属于本项目所有权范围的类型错误。
+ - `packages/*/*` 对 `vendor` 的包依赖解析到 `vendor/*/lib`，以适应不同的 tsconfig 严格度。
+
+
+## 决策
+
+包内相对导入使用显式 `.ts` 说明符。
+
+`pnpm run build` 是两阶段构建：
+
+- 阶段 1：在根 solution 上执行 `tsc -b`，将逐模块的 `.js`、声明文件 `.d.ts`、JS sourcemap `.js.map` 和声明 sourcemap `.d.ts.map` 输出到各包的 `lib/types`。这是权威的 TypeScript 编译结果。发布时保留 `.d.ts` / `.d.ts.map`，忽略 `.js` / `.js.map`。
+ - 该图是从根 solution `tsconfig.json` 经两个聚合可达的 project-reference 图（[拓扑](2026-07-22-tsconfig-solution-root-two-aggregates.md)），用于校验并输出包/vendor 的构建结果。
+- 阶段 2：打包器读取 `lib/types` 下输出的 JS，将打包后的运行时入口写为 `lib/index.js` 或 `lib/index.mjs`（沿用当前行为）。此阶段仅做打包，禁止读取 TypeScript 源码或输出声明文件。
+
+`tsdown` 不再负责 TypeScript 编译或声明文件输出。
+
+`pnpm run typecheck` 运行同一张 `tsc -b` 图。
+- 两个聚合（`tsconfig.host.json`、`tsconfig.client.json`）以 `noEmit` 方式检查示例、测试和脚本，并通过 references 校验包/vendor 源码。
+- 被引用的包/vendor 项目保持与构建相同的输出行为，因此类型检查会刷新它们的 `lib/types` 输出，而无需使用独立的 no-emit 图。项目特定的严格度变更放在各自的 `packages/*/*/tsconfig.json` 或 `vendor/*/tsconfig.json` 中。
+- 两个 no-emit 聚合禁用 `rewriteRelativeImportExtensions`；它们不输出任何文件，且包含跨 project-reference 边界导入 helper 的测试。包/vendor 的 emit 项目保持重写开启。
+
+复合项目将增量构建信息保存在各项目本地的 `lib/` 输出中。`pnpm run clean` 会根据根 TypeScript project-reference 图确定当前有效的输出目录，删除遗留的根目录构建信息，并删除已删除包留下且仅包含已知生成残留的 `packages/*/*` 目录。对于仍有 `package.json` 的每个包，该命令都会保留 `node_modules`；如果不含 `package.json` 的目录中存在未知文件，则拒绝删除。构建不会自动调用 clean，因此常规构建会保留增量状态。
+
+命令编排结构如下：
+
+```sh
+pnpm run build:
+tsc -b
+tsdown
+
+pnpm run verify-node-next-types:
+tsx scripts/verify-node-next-types.ts
+
+pnpm run typecheck:
+tsc -b
+
+pnpm run clean:
+tsx scripts/clean.ts
+```
+
+`pnpm run demo:*` 仍通过 tsx 和根路径直接运行 `src`，无需编译步骤。
+
+## 曾考虑的替代方案
+
+- **继续使用 `tsdown`/oxc 作为 TypeScript 转换器**：oxc 的转换行为与 `tsc` 不同（装饰器转换有差异、打包 JS 与逐文件输出不同），且其打包 `.d.ts` 与 Cordis 内部的相对模块增强结构冲突。
+- **用一个根目录严格程序覆盖包、vendor、示例、测试和脚本**：vendor 源码在根目录严格标志下会触发不属于本项目所有权范围的类型错误；带有逐项目严格度的 project references 才是可行的边界。
+- **每次构建前都执行清理**：即使工作区布局没有变化，这也会丢弃 `tsc` 和打包器拥有的增量状态。
+- **删除所有包级 `node_modules`**：有效的包依赖链接不会导致工作区发现失败，而删除这些链接会使构建清理变成重新安装依赖。
+
+## 后果
+
+构建职责更加清晰：
+
+- `packages/<group>/<pkg>` 和 `vendor/*` 下的每个模块有一份本地 tsconfig，同时服务于构建、类型检查和直接运行源码的工具（如 `tsx` 和 `vitest`）。
+- `build` 命令驱动根 solution 图。`tsc -b` 负责可发布的逐模块 `.js` 和 `.d.ts` 输出，打包器仅负责 `lib/index.*`。
+ - `lib/types/*.d.ts` 和 `.d.ts.map` 是发布用的声明输出。
+ - `lib/types/*.d.ts` 使用显式 `.ts` 相对说明符，TypeScript 的 NodeNext/Node16 解析器会将其映射到同级的 `.d.ts` 文件。
+ - `lib/types/*.js` 仅作为打包器输入，禁止用作运行时入口或公开导入目标。
+ - `lib/index.*` 是发布用的运行时输出，由打包器（当前为 `tsdown`）生成。
+- `pnpm run verify-node-next-types` 扫描构建出的声明文件，检查是否存在缺少文件扩展名的相对说明符，然后以 `moduleResolution: "NodeNext"` 对构建出的 `types`/`exports` 接口进行临时外部 ESM 消费方的类型检查，确保声明说明符的回归在发布前被捕获。
+- `typecheck` 命令使用 `tsconfig.json`。示例、测试和脚本由根 no-emit 项目检查，包和 vendor 模块保持与 `build` 相同的输出行为。包和 vendor 源码始终处于 project-reference 边界之后。
+- 切换分支或更新工作副本后，如果其中删除了包，贡献者可在重新构建前运行 `pnpm run clean`，删除残留的包目录。不含 `package.json` 的包目录如果存在未知文件，必须手动判定其类别，不能直接删除。
+
+Cordis 的 vendor 副本现在与上游多了一处类型结构差异。在上游同步时，该差异必须被重新应用或明确废弃。

## Problem
Docs in this repo link to each other by relative path — `[topic](../implemented/2026-…-….md)`, `[the cookbook](adding-a-tool.md)`, `[architecture.md](../../architecture.md)`. Nothing verified those targets exist. A rename or a move silently breaks every inbound link, and the break is invisible until a reader clicks it. [Doc-sync enforcement](2026-06-11-doc-sync-enforcement.md) already mechanized two classes of doc drift (uncompilable code blocks, a stale event-taxonomy table) and [verify-md-wrap](2026-06-11-doc-sync-enforcement.md) a third (hard-wrapped prose) — but a dead cross-link is a fourth, equally mechanical class that was still verified by eyeball.

+# Agent Note: Markdown 交叉链接有效性检查
+
+Status: implemented
+
+[English](2026-06-18-markdown-cross-link-lint.md) | 中文
+
+## 问题
+
+本仓库的文档通过相对路径互相链接：`[topic](../implemented/2026-…-….md)`、`[the cookbook](adding-a-tool.md)`、`[architecture.md](../../architecture.md)`。此前没有任何机制验证这些目标是否存在。重命名或移动文件会静默破坏所有指向它的链接，且在读者点击之前不可见。[Doc-sync 强制](2026-06-11-doc-sync-enforcement.md)已经将两类文档漂移机械化（无法编译的代码块、陈旧的事件分类表），[verify-md-wrap](2026-06-11-doc-sync-enforcement.md) 覆盖了第三类（硬换行的段落），但死链是第四类同样可机械检查、却仍靠肉眼验证的问题。
+
+引入这道门禁的直接动因是 Agent Note（agent 决策记录）目录树重组：将 `docs/adr/` 与 `.agents/notes/` 统一到同一个 `.agents/notes/` 下，并设置 `proposed/`、`implemented/`、`rejected/` 子目录，需要手工重命名约 40 条文档间链接。只要有一处路径输入错误，就会在没有任何检查拦截的情况下交付断链。
+
+## 决策
+
+新增第四道 `doc-sync` 门禁 `verify-md-links`（`scripts/verify-md-links.ts`），风格与 `verify-md-wrap` 一致（tsx ESM、基于 AST、只验证不生成）：
+
+- 使用 `mdast-util-from-markdown` + GFM 解析每个范围内的 Markdown 文件，遍历所有 `link`、`image` 和 `definition` 节点。
+- 仅当目标是**相对路径**时才检查。跳过带协议的 URL（`https:`、`mailto:` 等）、协议相对路径（`//host`）、根绝对路径（`/path`，在检出目录中没有稳定基准）以及纯页内锚点（`#section`）。剥除 `#fragment`/`?query`，相对于链接所在文件的目录解析路径，并断言目标在磁盘上存在。
+- 只报告、不改写；发现第一条死链即以非零状态退出。
+
+检查范围与其他门禁一致，并额外包含 AGENTS.md 文件对以及 `.agents/skills/` 下仓库自有的 agent-skill（技能）Markdown（这些 skill 文件会交叉链接到 docs 目录树，因此本次重组也改写了其中的链接）：`README.md`、`docs/**/*.md`、`packages/*/README.md`、`AGENTS.md`、`packages/AGENTS.md`、`.agents/skills/**/*.md`。系统按真实路径去重（`CLAUDE.md` symlink 会解析到 AGENTS.md 文件）。该检查接入 `doc-sync`，因此相关文档变更与 CI 执行同一套断链检查。
+
+本门禁检查的是*文件存在性*，而非锚点有效性：指向一个真实文件但带有 `#wrong-heading` 片段的链接仍会通过（文件可解析；片段被剥除）。
+
+## 曾考虑的替代方案
+
+**锚点级有效性检查**：更重且价值更低；实际造成问题的是文件级死链。这一范围裁剪是有意为之：作者在链接到某个锚点时自行验证 `#fragment`。
+
+## 后果
+
+- 造成交叉链接失效的重命名与移动会直接使 `doc-sync` 和 CI 失败，而不是等读者点击死链才暴露。由此，引入该门禁的 Agent Note 重组具备自校验能力：同一个 PR（Pull Request）在改写 40 条链接的同时，也添加了证明这些链接均未悬空的检查。
+- `doc-sync` 链中多了一个快速 tsx 脚本；无新增依赖（mdast/GFM 技术栈已作为 `verify-md-wrap` 的 devDependencies 存在）。
+- 该门禁强制执行的约定是：文档交叉引用必须使用可机械检查的相对链接，绝不能只写纯文本或编号。[docs/AGENTS.md](../../../../docs/AGENTS.md)记录了这项约定，使作者了解该门禁及其理由。

## Problem
A lifecycle-only Agent Note tree — `proposed/` / `implemented/` / `rejected/` — does not record what *kind* of decision each file contains. A reader browsing one lifecycle cannot distinguish a new capability from a removal or a tooling-policy change without opening each file.

+# Agent Note: 通过路径编码的子目录对 Agent Note 进行分类
+
+Status: implemented
+
+[English](2026-06-20-agent-note-classification.md) | 中文
+
+## 问题
+
+仅按生命周期组织的 Agent Note（agent 决策记录）目录树（`proposed/` / `implemented/` / `rejected/`）无法记录每个文件包含哪一*类*决策。读者浏览某个生命周期时，如果不逐一打开文件，就无法区分新功能、移除项或工具策略变更。
+
+本仓库一贯的倾向是[机械质量门禁优于行文规范](2026-06-11-quality-gates.md)：不被机器检查的约定终将腐烂。因此这里的分类方案必须可强制执行，而非靠自觉的文件头。
+
+## 决策
+
+增加第二个维度，即 Agent Note 的**类别**，并将其编码在路径中：`{lifecycle}/{class}/yyyy-mm-dd-topic.md`。文件夹*就是*标签。文件位置声明其类别；封闭集合限定为「这些文件夹且仅限这些」；既有的 [verify-md-links](2026-06-18-markdown-cross-link-lint.md) 门禁已经保护移动文件所需的路径改写。
+
+### 六个类别的封闭集合
+
+| 类别 | 涵盖范围 |
+|---|---|
+| `feature` | 面向用户或模型的新功能。 |
+| `bug-fix` | 修正缺陷或填补事后复盘暴露的空白。 |
+| `simplification` | 移除代码、行为或对外表面积，不引入新功能。 |
+| `architecture` | 关于**交付源码**的结构性决策——包（package）之间的关系、运行时词汇。 |
+| `process` | **围绕**代码的工具、策略或工作流，而非运行时行为。 |
+| `testing` | 测试基础设施与策略。 |
+
+`architecture` 与 `process` 的分界是：**architecture** 关乎我们交付的源码；**process** 关乎源码周边的工具与工作流。本 Agent Note 本身属于 `process` 决策：它改变仓库的组织方式与门禁，而不是 harness 的运行时行为，因此位于 `implemented/process/` 下。
+
+### 两道门禁
+
+两者都是 `doc-sync`（文档同步门禁）的成员，风格与 `verify-md-wrap` 一致（tsx ESM，只校验不生成，首个违规即以非零退出码退出）：
+
+- **`scripts/verify-agent-note-classification.ts`**：定义封闭的生命周期与类别集合。它断言生命周期文件夹下的每个文件都位于规范集合中的类别文件夹内（生命周期根目录下散落的 `.md` 或未知类别文件夹都会失败），并拒绝集中式 `INDEX.md`。规范集合位于 `scripts/agent-note-tree.ts` 中，[README](../../README.md)则以行文记录每个类别。
+- **`scripts/verify-doc-refs.ts`**：检查引用文档的源码注释。Agent Note 路径不仅出现在 Markdown 中，也出现在 TypeScript 文档注释中（例如以仓库根为起点的 `.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md`）。`verify-md-links` 看不到这些引用，因此目录重组可能静默留下失效引用。该门禁扫描 `packages/**` 与 `examples/**` 下仓库自有的 `.ts` 文件（排除已构建的 `lib/` 与 `vendor/`），查找 `docs/….md` 和 `.agents/notes/….md` token，解析每个以仓库根为起点的路径并断言其存在。它要求使用 `.md` 扩展名，因此不处理无扩展名的行文。
+
+## 曾考虑的替代方案
+
+- **在每个文件中添加 `Classification:` 行文行**（紧邻 `Status:`），由门禁解析。可行，但它将路径已能承载的事实重复到文件中，且行内容可能与所在文件夹不一致。路径编码使标签与其存储合二为一，没有需要保持同步的东西。
+- **设立 `refactor` 类别。** 与 `simplification` 几乎完全重叠；唯一有人试图用来区分的标准是「可观察行为是否改变？」，而 `simplification` 已经编码了这一点（它不改变）。一个类别即可，无需两个。
+- **生成或手工维护的语料索引。** 不予采纳：生命周期/类别目录树才是权威结构；集中式清单会制造合并热点，却没有提供目录树导航或仓库搜索无法实现的发现能力。单独的[索引提案](../../rejected/process/2026-07-04-generate-agent-note-index-tables.md)记录了被放弃的生成形状。
+
+## 后果
+
+- 每份 Agent Note 都位于一个类别文件夹下。读者浏览单个文件夹，即可查看某个生命周期内的全部简化或测试决策。
+- `doc-sync` 链中多了两个快速 tsx 脚本；无新依赖（mdast/GFM 栈已因 `verify-md-wrap`/`verify-md-links` 而存在）。
+- 新增类别必须是显式决策：修改 `scripts/agent-note-tree.ts` 中的 `const` 与 [Classification 章节](../../README.md#classification)，而不是只用 `mkdir` 创建文件夹。门禁会拒绝未知文件夹，因此临时类别无法悄然混入。
+- 源码注释中的文档引用同样受门禁约束：被 `.ts` 注释引用的文档一旦移动或重命名，`doc-sync` 与 CI 中的 `verify-doc-refs` 就会失败，从而堵住 `verify-md-links` 在结构上无法发现的一类漂移。

## Problem
A reader trying to understand the harness could find its *behavior* in [architecture.md](../../../../docs/architecture.md) (the service map, the session/turn/step lifecycle, the event taxonomy) but had no single place describing its *vocabulary* — the data structures that behavior moves around. The type shapes lived only in source, scattered across `packages/*/src/types.ts`, so understanding "what is a `Message`, a `SessionEvent`, a `StreamChunk`" meant reading the declarations directly. A prose catalog would help, but a catalog that paraphrases or paste-copies type definitions rots the instant a field changes — and an out-of-sync type doc is worse than none, because a reader trusts it.

+# Agent Note: 核心数据结构目录与 `ts type-equiv` 漂移门禁
+
+Status: implemented
+
+[English](2026-06-20-core-data-structures-catalog.md) | 中文
+
+## 问题
+
+试图理解 harness 的读者可以在 [architecture.md](../../../../docs/architecture.md) 中找到它的*行为*（服务图、会话/轮次/步骤生命周期、事件分类），却找不到一个统一描述其*词汇*的地方，也就是这些行为所传递的数据结构。类型形状只存在于源码中，散落在 `packages/*/src/types.ts` 各处，因此要理解“什么是 `Message`、`SessionEvent`、`StreamChunk`”，就必须直接阅读声明。文字目录会有所帮助，但复述或复制粘贴类型定义的目录会在字段发生变化时立即腐化，而不同步的类型文档比没有文档更糟，因为读者会信任它。
+
+因此，这项工作有两个相互交织的问题：**这样的目录应包含什么**（范围问题——harness 有数十种跨包（package）边界的类型，把它们全部倾倒进来对谁都没有帮助），以及**如何避免粘贴的类型定义发生漂移**（持久性问题）。本 Agent Note（agent 决策记录）记下了这两项决策。与它配套的[生成式 Cordis 事件与服务目录](2026-06-20-generated-cordis-catalog.md)从*接线*维度形成补充：本文对数据结构编目，另一篇则对传递这些结构的事件和服务编目。
+
+## 决策
+
+新增的 `docs/core-data-structures/` 目录对这些词汇编目，并配有新的 `verify-type-equiv` 文档同步门禁，使每个粘贴的类型声明及其 JSDoc 与源码保持同步。
+
+### 何为"核心"——主干与 seam 的分界线
+
+范围界定并非自上而下拍定，而是将候选定义逐一对照具体的边界类型反复测试，直到一条规则在所有案例中都成立。决定性的测试是 `BashExecRequest`/`BashExecSpec`/`BashRunResult`：bash 是一个能力 *seam*，不属于 agent loop（智能体循环）主干；如果这些算"核心"，那么"核心"就意味着*所有跨包词汇*，目录沦为平铺罗列；如果不算，"核心"就意味着*中央主干*，bash 词汇归入子页面。后者胜出，由此确定了整体结构：一个**分层文件夹**，而非一份平铺文档。
+
+确定其余案例的规则是：***你编写、持有或接收的类型是核心；为其提供类型推导、渲染或持久化的机制是子页面细节。*** 逐一验证如下：
+
+- 一个数据结构是**核心**的，如果它流经 agent loop 主干——无论加载了哪些插件，循环在每个轮次都会持有、派生、流式输出或记录它（`Message`、`StreamChunk`、`SessionEvent`、`Agent` 句柄）——**或者**它是插件作者面对某条流水线时编写的唯一标志性类型（`ToolDefinition`）。
+- `ToolDefinition` 是核心（它是每个工具作者编写的东西），**即使循环从不持有它**——对于这一个标志性类型，撰写重要性压过了严格的"流经主干"规则。但它的类型推导机制——`ValueSchemaSpec`、`ParameterSchemaSpec`、`InferValue` 与 `InferArgs`——是子页面细节。这就是主干与 seam 分界线的精确表述。
+- `ToolSchema` 是核心（它是流经每个步骤的模型请求 `GenerateOptions` 的一个字段），即使它在概念上属于工具流水线——当*流经主干*与*概念归属*冲突时，前者胜出。
+- 工具展示词汇（`ToolCallView`/`ToolResultView` 等）、`SessionPersistence` 持久性 seam 以及 bash 词汇是子页面。
+
+`core.md` 是一份**自包含的主干文档**：它给出每个主干结构的确切类型定义，辅以最少的行文，并链接到子页面获取各 seam 的细节。子页面包括 `llm-streaming.md`、`session.md`、`persistence.md`（沿内存模型与持久性 seam 的分界线从会话页面拆出）、`tools.md` 和 `bash.md`。
+
+### `ts type-equiv` 机制——既逐字又防漂移
+
+持久性要求很具体：文档展示当前类型声明与原始 JSDoc 的**逐字**内容（让读者看到真实形状和源码契约，而非复述），**并且**以机械方式保证其与源码匹配。仓库已经会编译 ` ```ts ` 围栏块（`doc-typecheck`），但真正接受类型检查的块需要导入噪音，而且只能证明*可赋值性*——字段改名或 JSDoc 变化仍可能通过。因此：
+
+- 完整的类型声明及其 JSDoc 会逐字粘贴到专用的 ` ```ts type-equiv ` 围栏中。简洁的 ` ```ts public-api ` 围栏承载与源码等价的类环境投影，用于实现体不应进入目录的类。`doc-typecheck` 会识别并跳过这两种围栏（裸声明无法独立编译），并且**将它们排除在 opt-out 比例之外**——它们是单独受检的类别，而不是未经检查的草图。
+- 新增的 `scripts/verify-type-equiv.ts` 通过 TypeScript 解析器提取每个块，并断言其声明结构和每条 JSDoc 注释都与所声明的符号匹配，只忽略格式空白和非 JSDoc 注释。普通块保留完整声明。`public-api` 投影保留类的公共字段、构造函数、访问器和方法及其原始 JSDoc，同时移除实现体以及私有或受保护成员。之所以选择它而非编译式 `_Check` 断言，是因为目录所保留的是源码名称与文档一致性，而不是可赋值性。
+- 来源信息存放在集中的 `scripts/type-equiv.manifest.json`（`{ doc, symbol, source }` 条目）中，**而非**行文中的指令注释。脚本强制执行 **1:1 对应**：每个 type-equiv 块恰好有一条 manifest 条目，反之亦然；因此一个块永远不会被静默漏检，一条条目也永远不会腐烂。
+- 接入 `doc-sync`，因此相关文档变更会在本地运行它，CI 也会与其他文档检查一起运行它。
+
+### 维护是作者的职责，门禁作为兜底
+
+`verify-type-equiv` 能捕获已记录类型的*粘贴漂移*，但无法告诉你一个全新的核心类型没有被记录。因此 AGENTS.md 和 `dsh-code-review` skill（技能）已更新，要求在变更添加或重塑已记录类型时同步更新目录——门禁处理漂移，人处理新增表面。
+
+## 曾考虑的替代方案
+
+- **平铺罗列所有跨包词汇**：`BashExecRequest` 测试案例否决了它。如果 seam 词汇算"核心"，目录对谁都没帮助；分层的主干与 seam 结构胜出。
+- **用编译式 `_Check` 可赋值性断言**代替源码匹配：否决。可赋值性不会保留名称或 JSDoc；同类型字段改名或契约注释变化仍会通过。
+- **来源信息作为行文中的指令注释**：否决，改用集中 manifest；其强制的 1:1 对应确保一个块永远不会被静默漏检，一条条目也永远不会腐烂。
+
+## 验证教训
+
+主干与 seam 规则在采纳前经过了 `BashExecRequest`、工具 schema 与定义、schema DSL、展示类型以及会话/持久化拆分的逐一测试。
+
+`verify-type-equiv` 必须扫描完整的 Markdown 范围，而不仅是清单点名的文档。否则，未列入清单的 `type-equiv` 块就会逃过所宣称的一一检查。因此，门禁会将此类块报告为孤儿。本 Agent Note 将这条失败关闭扫描规则，连同主干与 seam 的分界决策及逐字匹配决策一并记录；生成式 Cordis 目录在[其 Agent Note](2026-06-20-generated-cordis-catalog.md) 中有对称的设计记录。
+

## Problem
A plugin author needs two reference surfaces that no single document gave them: every cordis **event** they can listen to (with its exact signature and dispatch mode) and every `ctx.<key>` **service** they can call (with its exact interface). The pieces existed but were scattered — a hand-maintained event-taxonomy *table* in `docs/architecture.md` (names + prose Mode/Purpose, name-set-checked by `verify-event-taxonomy`), a Service-map table (8 rows of role prose), and the `interface Events` / `interface Context` declarations themselves. The taxonomy table also could not catch a brand-new *undocumented* event: a name-set verifier only checks the names that are already in the table on both sides.

+# Agent Note: 生成式 Cordis 事件与服务目录
+
+Status: implemented
+
+[English](2026-06-20-generated-cordis-catalog.md) | 中文
+
+## 问题
+
+插件作者需要两个参考面，而此前没有任何单一文档能提供：他们可以监听的每一个 Cordis **事件**（含精确签名与分发模式），以及他们可以调用的每一个 `ctx.<key>` **服务**（含精确接口）。相关信息虽然存在，但散落各处：`docs/architecture.md` 中一张手工维护的事件分类*表格*（名称 + 行文描述的 Mode/Purpose，由 `verify-event-taxonomy` 做名称集合校验）、一张服务映射表（8 行角色描述），以及 `interface Events` / `interface Context` 声明本身。分类表格还有一个盲区：它无法捕获全新的*未记录*事件——名称集合校验器只检查两侧已有的名称。
+
+这是对[核心数据结构目录](../../../../docs/core-data-structures/core.md)（[其 Agent Note（agent 决策记录）](2026-06-20-core-data-structures-catalog.md)）在接线维度上的补充：前者对循环传递的*数据结构*编目（经验证的手工粘贴），本文则对传递它们的*事件和服务*编目。
+
+## 决策
+
+从源码生成目录，取代手工维护表格并校验子集的方式。
+
+`scripts/gen-cordis-catalog.ts` 使用 TypeScript 编译器 API，根据声明和源码 JSDoc 分别生成事件与服务参考。事件包含分派模式及其原始成员 JSDoc；服务包含公共签名及各方法的原始 JSDoc。确定性的 `--write` 和 `--check` 模式使两个页面成为生成产物，并由 `doc-sync` 强制检查新鲜度。
+
+纯生成在此处是正确的，因为代码库足够规范，AST 就是全部事实：每个事件/服务名称都是字符串字面量，可以往返映射到静态声明——不存在动态命名的事件，也不存在仅运行时的服务。因此生成的文档不可能出错，且从结构上消除了未记录事件的缺口（生成器枚举源码，而非校验手写子集）。
+
+具体选择：
+
+- **`@mode` 标签，交叉校验。** 每个 harness 事件的 JSDoc 携带一个显式的 `@mode emit|waterfall|parallel|serial` 标签；缺少标签时生成器直接报错。当签名形状具有决定性时——尾部参数为 `next: () => …` 在结构上即为 waterfall（瀑布式事件）——生成器断言标签与之一致，矛盾时直接报错。emit/parallel/serial 的区别在结构上不可见（`session/flush` 返回 `Promise<void> | void` 且无 `next`，有序的 `agent/pre-step` 检查点亦然），因此信任标签。编写规则见 [AGENTS.md](../../../../AGENTS.md)。
+- **分层范围。** harness 层（8 个 `@deepseek-ai/dsh-*` 服务及其事件）从源码完整渲染。继承层（cordis-core 的 `ctx.on/emit/effect/provide/…` + `internal/*` 事件 + loader/hmr/timer）是插件同样可见的固定 vendor 源码；它从生成器中一张人工维护的表格简洁渲染（名称 + 一行描述 + 源码指针），而非遍历 vendor AST。原因是 cordis-core 的 `Context` 混合了真正的 ctx 成员与非服务字段（`root`、`baseUrl`、`logger`），且 vendor 接口面仅在有意的 vendor 同步时才变化。
+- **指向数据结构目录的交叉链接。** 签名中由仓库拥有的每个类型名（`GenerateOptions`、`StreamChunk`、`ToolDefinition`……）都会通过人工维护的映射链接到其主要核心数据结构页面。AST 遍历采用失败关闭策略：每个参数、泛型约束/默认值和返回类型引用都必须已映射、是签名自身的类型参数、是点名的 TypeScript/Cordis 基础类型，或带有点名的例外及其非目录文档归属。违规会连同源码位置汇总报告，并点明相应的归属列表。该映射不会复用 `type-equiv.manifest.json`，因为后者记录 `…Map` 符号，而签名引用派生的联合类型名，并且会在多个页面列出某些符号。
+- **专用围栏。** 签名块使用 ` ```ts cordis-catalog ` 信息字符串，并把原始事件或公共方法 JSDoc 直接放在其声明之前。`doc-typecheck` 会识别并跳过这些裸片段，将其排除在 opt-out 比例之外——与 `type-equiv` 块的处理相同。
+
+本决策**取代** [doc-sync 强制](2026-06-11-doc-sync-enforcement.md)中事件分类的那一半：`verify-event-taxonomy` 及其 `docs/architecture.md` 表格退役（architecture.md 的标题保留，正文改为指向目录；服务映射的角色表格作为人工行文保留）。doc-typecheck、verify-md-wrap、verify-md-links 和 verify-type-equiv 不受影响。
+
+## 曾考虑的替代方案
+
+- **校验而非生成（退役的分类检查所做的事）**：*仅对本参考面*反转了这一策略。此处的数据可以机械地完整获取，因此生成严格强于对手工表格做名称集合校验（完整签名、不会漂移、能捕获未记录事件）。
+- **遍历 vendor AST 以获取继承层**：否决，改用人工维护表格。cordis-core 的 `Context` 混合了真正的 ctx 成员与非服务字段，且固定的 vendor 接口面仅在有意同步时才变化。
+- **复用 `type-equiv.manifest.json` 作为签名交叉链接映射**：否决，改用完整的人工维护常量和失败关闭覆盖。清单记录 `…Map` 符号，而签名引用派生的联合类型名，并且会在多个页面列出某些符号。显式映射让每个渲染目标和每个非目录例外都成为可评审的决策。
+
+## 后果
+
+- 目录不会发生漂移：提交文件未反映的源码变化会使 `doc-sync` 和 CI 中的 `verify-cordis-catalog` 失败。新事件缺少 `@mode` 标签、标签与其签名冲突，或签名类型未分类，都会直接使生成器失败。
+- 事件与服务方法契约只有一个归属——声明处的 JSDoc。目录会在生成的签名块中重复该原始 JSDoc，并使用其描述部分作为条目正文，因此单薄的源码文档只会生成单薄的目录条目。
+- 继承层是手工摘要，因此 vendor 同步若新增或重命名了 cordis-core 事件或 `ctx` 成员，需要同步编辑 `gen-cordis-catalog.ts` 中的人工维护表格。这是不遍历固定 vendor 源码的有意代价；它很少变化，且在生成器中有明确标注。
+- `verify-event-taxonomy.ts` 被删除，`docs/architecture.md` 的事件表格也已移除；之前链接到特定表格行的人现在会落在生成目录上。

- **Paired sibling files with equal authority.** A documentation pair is three sibling files: English `foo.md`, Chinese `foo.zh.md`, and a consistency record `foo.i18n.yaml`. Neither language is canonical — a document may be authored and reviewed Chinese-first and translated to English afterwards, or the reverse; what binds the pair is that both sides must say the same thing, and pairs merge whole (both languages plus the record, never one alone). Policy: [docs/i18n/README.md](../../../../docs/i18n/README.md); translation rules: [docs/i18n/translation-rules.md](../../../../docs/i18n/translation-rules.md); terminology source of truth: [docs/i18n/terminology.md](../../../../docs/i18n/terminology.md).
- **A sidecar record of both blob hashes makes consistency checkable.** `foo.i18n.yaml` holds the full git blob hash of each side as of the last confirmed-consistent state. An edit to either side without re-confirming the pair is then mechanically detectable as a pure content comparison — no history lookup — and the hashes are computable for files edited in the same PR, which a commit-hash record is not. Re-recording (`verify-translation-pairing --write`) produces a reviewable yaml diff: confirming consistency is an explicit, visible act in the PR.
- **`verify-translation-pairing` joins `doc-sync`.** The gate ([scripts/verify-translation-pairing.ts](../../../../scripts/verify-translation-pairing.ts)) enforces: required pairs exist, every existing pair is complete (all three files) and consistent (both hashes match, switcher links both ways, structural signatures identical), excluded (generated or bilingual-by-construction) files stay unpaired, and date-named documents on or after the manifest's `requiredSince` cutoff have complete pairs. The `required` list in [scripts/translation-pairing.manifest.json](../../../../scripts/translation-pairing.manifest.json) is a ratchet: each merged translation batch adds its files, so coverage only grows.
+- **The enforcement frontier advances in coherent review batches.** A related set enters `required` only when reviewers can evaluate it as a unit. The core frontier groups [architecture](../../../../docs/architecture.md), the [Cordis primer](../../../../docs/cordis-primer.md), [defensive patterns](../../../../docs/defensive-patterns.md), the [glossary](../../../../docs/glossary.md), and [testing](../../../../docs/testing.md) because their terminology, links, and contributor contracts inform one another; admitting only part would leave the enforced corpus internally inconsistent. A site-published pair uses `pairedPages()` so the root locale projects `.zh.md` and `/en/` projects `.md`; creating a counterpart alone does not publish it.
+- **Pairing records are metadata, not Cordis Loader configuration.** Cordis configuration discovery accepts actual `.cordis.yml` and `.cordis.yaml` files while excluding `*.i18n.yaml`, even when the document name contains `cordis`. This preserves validation of executable Loader entries without parsing translation hashes as configuration.
- **Translation is agent work with human review.** The committed workflow is [.agents/skills/dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md), following the same pattern as [dsh-code-review](../../../skills/dsh-code-review/SKILL.md): the skill carries the workflow and defers to the docs as sources of truth. The skill directs the orchestrating agent to delegate translation writing to a subagent.
+## Verification
+
+The verification contract covers each boundary independently. `verify-translation-pairing` pins pair completeness, hashes, switchers, and structure; [`project-doc-site.spec.ts`](../../../../scripts/project-doc-site.spec.ts) pins locale-specific source selection for published pairs; [`cordis-config-files.spec.ts`](../../../../scripts/cordis-config-files.spec.ts) pins discovery of Loader YAML and exclusion of translation records; and the [translation-prompt runnable snapshot](../../../../scripts/translation-prompt.snapshot.ts) pins the rendered system message, five reviewed example pairs, source request, and consumed response. Together these checks make pair drift, publication drift, configuration misclassification, and model-visible prompt drift review-visible.
+
## Alternatives considered
- **English as the canonical source with a fingerprint inside the translation** — the design first proposed for this Agent Note: `.zh.md` files carried an HTML comment recording the English source's blob hash, and translation flowed EN → ZH only. Revised in review: the team wants Chinese-first authoring (write and review a Chinese Agent Note, then translate to English) with the two languages holding equal authority, which a one-directional canonical model cannot express. The sidecar record covering BOTH sides replaced the in-file one-directional fingerprint; the blob-hash mechanics survived unchanged.

+- **配对记录是元数据，而不是 Cordis Loader 配置。** Cordis 配置发现会接受实际的 `.cordis.yml` 和 `.cordis.yaml` 文件，同时排除 `*.i18n.yaml`，即使文档名中包含 `cordis` 也不例外。这样既能继续校验可执行的 Loader 配置项，又不会把翻译 hash 当作配置来解析。

+# Agent Note: 生成式工具 schema 目录（启动并采集）
+
+Status: implemented
+
+[English](2026-07-02-tool-schema-catalog.md) | 中文
+
+## 问题
+
+仓库此前没有一份统一的参考文档来记录实际暴露给模型的工具名称、描述与 JSON Schema。源码声明分散各处且在运行时组合，而既有的 Cordis 目录和数据结构目录覆盖的是接线与词汇，而非工具。
+
+## 决策
+
+目录通过**启动每个工具插件并读取其已注册 schema** 来生成，而不是解析源码。`scripts/gen-tool-catalog.ts` 在全新的 Cordis `Context` 上挂载每个已发布工具包（package）；该上下文还提供 `SystemPrompt`、`ToolRegistry` 以及插件 `apply` 所读取的注入 seam。生成器调用 `ctx.tools.schemas()`——也就是发送给模型的确切 `ToolSchema[]`——随后释放上下文，并为每个包渲染一个 `## <package>` 章节，每个工具附带一个 ` ```json ` `parameters` 块。它与 `gen-cordis-catalog` / `gen-module-graph` 的 CLI 形状一致：默认 `--write` 重新生成；提交副本陈旧时 `--check` 失败；输出具有确定性（按清单排序，工具按名称排序）。`verify-tool-catalog`（即 `--check`）在 `doc-sync` 内运行，因此相关文档变更和 CI 会执行同一项新鲜度检查。
+
+### 为何启动而非解析（核心要点）
+
+Cordis 目录是纯 TypeScript AST 遍历，因为每个事件/服务名都是字符串字面量，可以往返映射到静态声明——AST 即全部事实。**工具 schema 在静态层面不可知**，因此同样的技术会产出一份说谎的文档：
+
+- `tool-todo` 写了 `enum: [...STATUSES]`——对一个运行时 `const` 的展开。AST 看到的是展开表达式，而非 `["pending","in_progress","completed"]`。
+- 每条 description 都通过字符串**拼接**构建（`'…' + '…'`）。AST 看到的是拼接节点，而非模型实际读到的最终文本。
+- `tool-subagent` 的工具名是 `config.toolName ?? 'subagent'`——加载时选定，并非字面量。
+- MCP 插件可以通过 `ctx.tools.register()` 直接注册**原始 JSON Schema**，完全不经过 `defineTool`，因此结构化枚举 `defineTool(` 调用点会遗漏。
+
+唯一准确的真源，是插件加载后注册表实际持有的 schema。启动插件是把[测试策略](../../../../docs/testing.md)中“验证现实，而非自我报告”的准则应用到文档生成器：读取已发布产物，而非重新推导一份。
+
+### 恢复「不会静默遗漏」的保证
+
+启动有一项 AST 遍历不存在的代价：没有源码声明集合可供枚举，新工具包可能被遗忘。一个**完整性守卫**恢复了这项保证——`assertManifestComplete` 对 `packages/` 下所有 `tool-*` 包进行 glob，若有任何一个不在生成器的启动 manifest 中则直接报错。新工具包在注册之前会导致生成器失败，进而导致 `doc-sync` 失败。这与 Cordis 生成器通过枚举源码免费获得的结构性属性相同，只是为基于启动的生成器重新实现了一遍。
+
+### 手动维护的启动 manifest 是不可化约的策略
+
+文件系统负责发现工具包清单，完整性守卫负责拒绝遗漏。`TOOL_PACKAGES` 仍然为每个包持有一份显式的启动配方，因为所需的 seam 实现和配置属于策略，不是能从目录布局或注入名称安全推断的事实。
+
+### 范围
+
+`packages/*/tool-*` 下已发布的产品工具包，每个都使用默认配置启动，包括 `dsh-tool-bash`（`bash`）、`dsh-tool-tasks`（`task_output`、`task_list`、`task_kill`）和 `dsh-tool-subagent`（`subagent`）。仅供示例使用的工具不在范围内。
+
+目录的单位是包，而非每个配置化的工具实例。每个包以默认配置启动一次；加载时的别名（如 `subagent_fork`）会注明，但不枚举所有部署排列。部署清单是一个独立的、无界的接口。
+
+### 使用普通 `json` 围栏
+
+schema 块使用 ` ```json `，而非自定义的 `ts` 系围栏。`doc-typecheck` 只提取 `ts*` 围栏，因此 JSON 块对它不可见——无需 `BlockKind` 接线（不同于 Cordis 目录的 `ts cordis-catalog` 围栏，后者需要加入白名单以避免裸签名片段被编译）。
+
+## 曾考虑的替代方案

+- **纯 TypeScript AST 遍历，如 Cordis 目录**：工具 schema 在静态层面不可知（见上文核心要点）：运行时展开、字符串拼接、配置选定的名称，以及原始 `ctx.tools.register()` 注册，都会让 AST 推导出的文档说谎。
+- **从各包的 inject 推断启动配方**：属于[发现包清单提案](../../proposed/process/2026-06-20-discover-package-inventory.md)所警告的「过度聪明」路径；配方保持为手写策略，清单由文件系统发现并由完整性守卫把关。
+- **为 schema 块使用自定义 `ts` 系围栏**：不必要。普通 ` ```json ` 围栏对 `doc-typecheck` 不可见，无需 `BlockKind` 白名单。
+
+## 后果
+
+- 目录不会发生漂移：提交文件未反映的工具 schema 变化会使 `doc-sync` 和 CI 中的 `verify-tool-catalog` 失败。新增的 `tool-*` 包若未加入清单，会直接使完整性守卫失败。
+- 工具描述文本有唯一归属——源码中 `defineTool` 的 `description`——生成的条目质量取决于它，与 Cordis 目录对事件 JSDoc 施加的强制力相同。
+- 生成器导入并执行工作区包（这是仓库中第一个这样做的脚本；其他脚本只读文本）。它通过根 `tsconfig` 的 `paths` 映射在 `tsx` 下运行，使用与演示和测试相同的未构建源码路径，因此不需要构建步骤。
+- 未来某个工具背后新增一个能力 seam，意味着 manifest 中需要新增一条配方条目（声明要挂载哪些 seam）。这正是上文指出的有意为之的手写成本；仅在新增工具包时才需变更。

+# Agent Note: 面向维护者与 SDK 用户的文档关系图索引
+
+Status: implemented
+
+[English](2026-07-03-documentation-graph-atlas.md) | 中文
+
+## 问题
+
+仓库已经有若干高可信文档表面，各自覆盖不同维度：[module-graph.md](../../../../docs/module-graph.md) 根据包（package）的 `peerDependencies` 生成；生成式 [Cordis 事件](../../../../docs/cordis-catalog/events.md)和[服务](../../../../docs/cordis-catalog/services.md)目录根据 Cordis `Events` 和 `Context` 声明生成；[tool-catalog.md](../../../../docs/tool-catalog.md) 通过启动已发布工具插件生成；[core-data-structures/](../../../../docs/core-data-structures/core.md) 则使用 `ts type-equiv` 块使粘贴的类型定义与源码保持同步。
+
+这些参考文档是准确的，但大多是目录式的。维护者仍需自行综合关系：哪些包构成一个能力 seam、哪个应用组装了具体的主干、哪些事件是持久的而哪些是实时的、钩子或策略插件在哪里可以拦截工作、以及哪个面向模型的工具依赖哪个服务。SDK 用户从另一个角度面临同样的问题：「我想要某种行为，应该安装或加载哪个包？应该扩展哪个事件/服务/工具？」
+
+钩子子系统使事件的生产者/消费方拓扑与拦截点变得更加重要；文件系统 seam 使能力 seam、策略否决、工具呈现与 SDK 组装路径变得更加重要。如果关系图的范围仅限于一个小的 bash/todo/subagent 表面，它们会立即陈旧。
+
+## 决策
+
+新增生成式关系图文档，由聚焦的生成器产出并在 [docs/graph-atlas.md](../../../../docs/graph-atlas.md) 建立索引；作为 `doc-sync` 的一部分，通过 `pnpm run verify-doc-graphs` / 现有目录新鲜度检查进行验证。
+
+该索引是既有目录之上的关系层。它不取代精确的参考文档，而是链接到它们并解释各部分如何组合在一起。
+
+### 维护模式
+
+每个关系图页面声明一种维护模式：
+
+- **Generated（生成）**：所有节点和边均从源码发现；如果已提交的产物陈旧，`--check` 失败。
+- **Hybrid generated（混合生成）**：源码发现清单，一个小型 manifest 对不可约的策略进行分类，完整性守卫在发现的条目未被分类时失败。
+- **Curated（人工策划）**：图表解释设计意图、时序或归属；它由生成器输出以使关系图文档保持为可重新生成的整体，但内容是有意撰写的。
+
+### 首批发布的索引
+
+该索引链接十种关系表面。包拓扑和工具包所提供的功能位于已经拥有这些事实的现有生成式目录中；其余聚焦图表由 `scripts/gen-doc-graphs.ts` 生成。
+
+| 关系图 | 维护模式 | 真源 |
+|---|---|---|
+| [模块依赖图](../../../../docs/module-graph.md) | 生成式 | `packages/*/*/package.json` 的对等依赖（peer dependency）与包分组路径 |
+| [工具 schema 目录与包映射](../../../../docs/tool-catalog.md) | 生成式 | 启动后采集的工具 schema，以及工具包服务/效应元数据 |
+| [能力 seam 与核心服务](../../../../docs/capability-seams.md) | 混合生成式 | Cordis 服务声明，以及 `gen-doc-graphs.ts` 中的角色清单 |
+| [tui-agent 应用组合](../../../../examples/tui-agent/composition.md) | 混合生成式 | `examples/tui-agent/cordis.yml` 插件列表，以及人工维护的应用/bundle 展开 |
+| [headless-agent 应用组合](../../../../examples/headless-agent/composition.md) | 混合生成式 | `examples/headless-agent/cordis.yml` 插件列表，以及人工维护的应用/bundle 展开 |
+| [cordis-agent 应用组合](../../../../examples/cordis-agent/composition.md) | 混合生成式 | `examples/cordis-agent/cordis.yml` 插件列表，以及人工维护的应用/bundle 展开 |
+| [acp-agent 应用组合](../../../../examples/acp-agent/composition.md) | 混合生成式 | `examples/acp-agent/cordis.yml` 插件列表加人工策划的应用/bundle 展开 |
+| [事件生产者/消费方矩阵](../../../../docs/event-producer-consumer.md) | 混合生成式 | Cordis 事件声明、经 AST 扫描的 `ctx.on/emit/parallel/serial/waterfall` 位置，以及显式动态分派覆盖 |
+| [agent 轮次与步骤生命周期](../../../../docs/agent-lifecycle.md) | 人工维护 | architecture.md 循环生命周期、Cordis 目录链接，以及会话事件语义 |
+| [工具执行管线](../../../../docs/tool-execution-pipeline.md) | 人工维护 | 工具管线语义与 `tools/execute` waterfall（瀑布式事件）|
+
+### 为什么由生成器拥有文档
+
+包拓扑留在 `gen-module-graph.ts`，工具-包能力映射留在 `gen-tool-catalog.ts`，因为这些生成器已经拥有权威事实和新鲜度门禁。`gen-doc-graphs.ts` 拥有其余关系页面和索引。代价是人工策划的图表需要在 TypeScript 字符串块中编辑，而非直接编辑 Markdown。对于首版来说这是可接受的，因为面向用户的产物仍然是纯 Markdown/Mermaid；未来如果撰写体验比可重新生成更重要，可以将人工策划的页面拆分出去。
+
+### 完整性守卫
+
+混合生成的页面在其 manifest 陈旧时必须显式报错：
+
+- 模块图读取每个包的 `peerDependencies`，并按 `packages/<group>/<pkg>` 路径对包进行分组。
+- 工具目录通过启动收集已发布的工具，并从同一份 manifest 渲染包/服务/副作用映射（其完整性守卫已在检查该 manifest）。
+- 能力 seam 图导入 Cordis 服务收集器，断言每个发现的 harness `ctx.<key>` 都已在 `SERVICE_ROLES` 中分类，且每个已分类的 key 仍然存在。
+- 事件生产者/消费方矩阵标记为 hybrid，因为 subagent 生命周期事件有意使用 `ctx.events.dispatch` 实现逐监听器隔离；这些动态边是显式覆盖而非无声遗漏。
+- `verify-mermaid` 使用 Mermaid 自身的解析器解析仓库中每个 ` ```mermaid ` 围栏，因此语法错误在本地和 CI 的 `doc-sync` 阶段即被捕获，而非在 GitHub 渲染时才显示为损坏的图表。
+
+## 曾考虑的替代方案
+
+已提交的图表使用 Mermaid，因为 GitHub 在 Markdown 中原生渲染它且不引入新的文档构建依赖；密集的多对多数据（如事件生产者/消费方关系）改用 Markdown 表格。**PlantUML、托管图表服务和生成的 SVG** 曾被考虑，但在 Mermaid 成为瓶颈之前有意不采用。
+
+## 后果
+
+- 维护者获得了拓扑、seam、事件流、生命周期与应用组合的可视化入口。
+- SDK 用户获得了从用例到包组合的路径，而非仅有自底向上的包参考。
+- `doc-sync` 现在包含 `verify-doc-graphs` 和 `verify-mermaid`，因此关系图漂移和 Mermaid 语法错误与其他文档新鲜度门禁一起被捕获。
+- 未来的文件系统和钩子工作有了承载新复杂度的具体位置：文件系统应扩展能力文档和工具目录，钩子应扩展事件矩阵和工具执行流水线。

+# Agent Note: 针对 Cordis 对外服务接口的 JSDoc 完整性门禁
+
+Status: implemented
+
+[English](2026-07-04-cordis-jsdoc-completeness-gate.md) | 中文
+
+## 问题
+
+生成的 Cordis 目录此前强制了事件分发模式，但未强制要求完整的服务与事件契约。方法可以缺少描述，参数或返回值可以在跨插件 API 接口上不写文档——而这恰恰是 IDE 引导最重要的地方。
+
+AGENTS.md 中的规则（「每个导出都有解释语义的 JSDoc」）只能靠评审以行文形式检查；本仓库的既定偏好是将不变式编码为机械门禁。「Cordis 服务函数与事件」这一范围有精确的机器定义，只有目录生成器知道：事件是 `declare module 'cordis'` 内 `interface Events` 的成员，服务接口是每个 `interface Context` 键所指向的类的公开方法。ESLint 规则看不到这层映射；生成器在每次运行时计算它。
+
+## 决策
+
+扩展 `scripts/gen-cordis-catalog.ts`——复用同一次遍历和同一套 `@mode` 先例——对它编目的所有内容强制执行 JSDoc 完整性要求。`verify-cordis-catalog` 在 `doc-sync` 内运行，因此相关文档变更和 CI 会执行同一门禁，无需另行接线。
+
+契约如下：
+
+- **事件**需要描述性文字，以及为每个**载荷参数**提供非空的 `@param`。载荷参数是携带事件数据的签名参数；`this` 接收者注解和尾部的 waterfall（瀑布式事件） `next` 免检——`next` 是分发机制，其语义已由 `@mode waterfall` 标签（及其结构交叉检查）拥有，逐事件重述只是样板代码。为免检参数写文档是允许的；只有缺失才被检查。
+- **服务类**需要类级 JSDoc，每个公开方法需要描述性文字、为每个参数提供非空的 `@param`，以及非空的 `@returns`——除非标注的返回类型是 `void`/`Promise<void>`（此时 `@returns` 可选——resolve 时机有时值得记录——但从不强制要求）。
+- **陈旧标签报错**：`@param` 命名了一个不存在的参数即为违规，与 `@mode` 与签名矛盾的检查对称。标签描述必须非空；超出此范围的语义质量由评审负责。
+- **遍历可检查的显式性**：门禁是纯 AST 遍历（不使用类型检查器），因此服务方法必须显式标注返回类型（推断的返回类型无法分类），接口参数必须是简单标识符（解构模式没有名称供 `@param` 匹配）。
+- **违规聚合**为一条错误信息，列出所有违规项——修复时一次看到完整清单。此前快速失败的 `@mode` 检查也移入同一份聚合报告，消息文本不变。
+
+生成器保留同一源码注释的两种视图：`parseJsDoc` 在第一个块标签处结束条目正文，而 `ts cordis-catalog` 签名块包含原始 JSDoc，并完整保留 `@param`、`@returns` 和 `@mode`。因此，读者可以看到完整的源码契约，而块标签文本不会泄漏到周围正文中。
+
+`packages/core/agent/tests/gen-cordis-catalog.spec.ts` 中的负路径测试对合成 fixture（测试前置数据）运行 `collectEvents`/`collectServices`，验证每条守卫都会触发且免检规则成立。撰写规则写在根 [AGENTS.md](../../../../AGENTS.md) 的约定条目中，与 `@mode` 规则并列。
+
+## 曾考虑的替代方案
+
+- **ESLint 规则**：无法看到该范围的机器定义（哪些 `interface Events` 成员、哪些 `ctx.<key>` 类构成 Cordis 对外服务接口）；目录生成器在每次运行时恰好计算这层映射，因此门禁放在那里。
+- **将每个方法展开为单独的正文小节**：否决。目录保留一个服务章节和一个签名块，以维持可扫读性；附着于每个声明的 JSDoc 则在原处保留完整的方法契约。
+- **逃逸标签**：不设。该接口面小且经过策展（采纳时 12 个服务、57 个方法、27 个事件），要点在于检查不可豁免。
+
+## 后果
+
+- 新事件或服务方法不能带着未记录的参数或结果落地：生成器会拒绝重新生成，`verify-cordis-catalog` 也会使 `doc-sync` 和 CI 失败。采纳时发现的约 139 处缺口已在同一变更中补齐，因此门禁以绿色状态落地。
+- 服务接口必须显式标注返回类型并使用标识符参数。两项约束在采纳时均未构成限制（所有方法已有标注；不存在解构的 seam 参数）；但二者现在是承重要求，违反时会被机械检测到。
+- AGENTS.md 中通用的 JSDoc 规则（「一行能说清就用一行」）在此接口上获得了更严格的特例：仅当方法无参数且返回 void 时，一行摘要才足够。
+- 为 `next` 或 `this` 写 `@param` 合法但不检查——这是有意的不对称：门禁强制载荷契约，拒绝要求样板代码。
+- 每个生成的事件或方法片段都带有其原始 JSDoc，而正文摘要不含标签。因此，源码编辑会同时刷新可读索引和签名旁展示的确切契约。

+# Agent Note: 文档分层、预算与上限门禁
+
+Status: implemented
+
+[English](2026-07-04-doc-tiers-and-budgets.md) | 中文
+
+## 问题
+
+尽管已有写作指导，常设文档仍不断累积重复规则、反复讲述的事件、重复的包（package）映射，以及陈旧的 Agent Note（agent 决策记录）摘要。仅靠评审无法阻止这种增长，因此仓库需要在文档分类之外再配一套机械预算。
+
+## 决策
+
+- **每项事实只归属一处的层级分类。**[docs/AGENTS.md](../../../../docs/AGENTS.md) 是文档标准：它为每种 Markdown 层级分配单一职责（常设指令、系统图、类型目录、决策记录、事件故事、操作指南、各包契约、生成式目录、工作流），禁止在事实归属层级之外重复陈述（应改为链接），并包含编写或评审任何文档时使用的赘余检查清单。
+- **范围窄且严格的预算门禁。**[scripts/verify-doc-budgets.ts](../../../../scripts/verify-doc-budgets.ts) 接入 `doc-sync`：[scripts/doc-budgets.manifest.json](../../../../scripts/doc-budgets.manifest.json) 列出的每份文档都必须低于其字数上限（采用 `wc -w` 语义，统计整个文件）；预算内文件缺失也会使门禁失败，使重命名无法悄然遗落其预算。范围刻意只涵盖容易膨胀的常设文档——根目录和子树中的 `AGENTS.md` 文件、`architecture.md`、`packages/README.md`，以及它们将内容移入的常设策略文档（`docs/testing.md`、`docs/defensive-patterns.md`）。参考文档、Agent Note 和包 README 不设预算：只要每一行都是事实，长度在这些位置就是合理的；评审和赘余检查清单负责约束它们。
+- **上限是只进不退的执行红线。** 上限设定为文档当前字数的至少 105%（留出工作余量，使日常措辞调整能通过，而真正的膨胀仍会触发门禁），并随着文档被精简到目标预算而同步下调、保持该余量（根 `AGENTS.md` ≤ 1,500 词；`architecture.md` ≤ 1,800；子树 `AGENTS.md` ≤ 600；`packages/README.md` ≤ 600）。推进机制与[翻译配对的 `required` 清单](2026-07-02-bilingual-docs-and-pairing-gate.md)相同。门禁变红时，修复方式是按分类体系迁移或压缩内容；只有在 PR（Pull Request）描述中给出明确理由时才允许提高上限，manifest（元数据清单）的 diff 本身即为可评审的动作。
+- **精简的工作流 skill（技能），契约归文档。**[.agents/skills/dsh-doc-standards](../../../skills/dsh-doc-standards/SKILL.md) 承载放置/审计/红灯门禁工作流，并以文档标准为真源，与 [dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md) 和 i18n 契约之间的分工相同。
+
+## 曾考虑的替代方案
+
+- **仅靠 skill 和评审纪律，不设门禁**：否决。上述膨胀正是在现行规则和评审注意力已经存在的情况下发生的；一条没有机械后盾的行文规则在此处已被证明无法维持，而本仓库自身的[质量门禁立场](2026-06-11-quality-gates.md)认为值得保持的不变式就值得编码。
+- **对所有文档层级全面设限**：否决。一刀切的上限恰好惩罚了那些正当的长文档（如特性矩阵或类型目录，每一行都是事实），并产生逐文件的例外变更，训练贡献者机械地批准提限。
+- **将标准放在 skill 内部**：否决。契约归文档，工作流归 skill；如果标准被塞进 SKILL.md，那些不调用该 skill 而直接编辑文档的 agent（智能体）就看不到它，而 `docs/AGENTS.md` 已经作为子树指令被任何在 `docs/` 下工作的人加载。
+
+## 后果

## Problem
`SessionEventMap` is the on-disk vocabulary, but its declarations are split across the owning session package and declaration merges. The generated persistence catalog is the single reference for every event, its complete payload declaration and source JSDoc, and the shared `SessionEvent` envelope; hand-maintained tables drift and are removed. These records are not Cordis events—observers receive them through the single `session/event` bus event—so the Cordis catalog cannot cover them. The generator discovers all declarations and the doc-sync freshness gate rejects omissions or stale output.

+# Agent Note: 生成式持久化日志事件目录
+
+Status: implemented
+
+[English](2026-07-04-persistence-log-catalog.md) | 中文
+
+## 问题
+
+`SessionEventMap` 是磁盘格式的词汇，但其声明分散在所属的会话包（package）和声明合并中。生成式持久化目录是所有事件、各自完整 payload 声明与源码 JSDoc，以及共享 `SessionEvent` 信封的唯一参考；手工维护的表格会发生漂移，因此被移除。这些记录不是 Cordis 事件——观察者通过唯一的 `session/event` 总线事件接收它们——所以 Cordis 目录无法覆盖。生成器会发现所有声明，文档同步新鲜度门禁会拒绝遗漏或陈旧输出。
+
+## 决策
+
+从源码生成 `docs/persistence-catalog.md`，配合新鲜度门禁，作为第四个参考面：持久化会话日志可以包含的*记录*，与 Cordis 目录（接线）、核心数据结构（词汇）和工具目录（工具）互补。
+
+`gen-persistence-catalog.ts` 使用 TypeScript AST 扫描每个所属及声明合并的 `SessionEventMap`。它从前置 JSDoc 开始渲染每个成员，直至完整的 payload 类型，保留嵌套属性注释且只移除其容器缩进；同时粘贴构成持久化信封的所属 `SessionEventType`、`SurfaceEventType`、`SurfaceOp` 和 `SessionEvent` 声明。派生的 surface 徽章、参考链接和源码位置仍位于声明块之外。文档同步新鲜度检查会拒绝目录尚未重新生成的词汇或信封变更。
+
+具体选择：
+
+- **强制保证 JSDoc 完整性。** 每个成员和渲染出的信封类型都必须带有描述正文，完整的源码 JSDoc 会在目录中保持附着于其声明。`@mode` 标签是硬错误：分派模式属于 Cordis 总线事件，持久化记录没有这种模式。所有违规会汇总为一条错误，列出每个违规项。
+- **surface 徽章由派生得出，而非手工列举。** `SurfaceEventType`（产生 LLM（大语言模型）消息且可能携带 `surfaceOp` 的子集）从拥有方包中的 union 声明解析；如果 union 成员命名了一个未声明的事件，则为硬错误（否则陈旧的 union 成员会静默地不标注任何内容）。其余一律渲染为 **log-only**。
+- **专用围栏。** 声明块使用 ` ```ts persistence-catalog ` 信息字符串，`doc-typecheck` 会识别并跳过这些块，将其排除在 opt-out 比例之外——处理方式与 `ts cordis-catalog` 相同（这些声明引用所属模块中的类型，无法独立编译）。
+- **仓库范围。** 目录枚举本仓库中的包，与兄弟文档的 packages-only 范围一致；下游插件可以合并更多事件类型，它们在设计上不在目录范围内。遍历过程用硬错误保护自身假设：拥有方的顶层 `interface SessionEventMap` 必须是 `@deepseek-ai/dsh-session` 中唯一的导出声明（无关的、局部的或同名重复的接口不能被当作磁盘词汇编入目录）；任何声明不得携带 `extends`（继承的键会加入 `keyof SessionEventMap` 却没有对应的目录行）；每个成员必须是带有显式 payload 类型的属性签名（方法形式的成员会加入 `keyof` 却在静默遍历中被漏过）；跨声明的重复成员也会失败。
+
+本方案取代了手工副本：session.md 的 `hook/*` 表格、精简版 README 的事件表格、hook-protocol README 的 payload 条目列表，以及会话 README 的名称列表现在链接到目录，而不再重述 payload（周围的语义说明文字保留原位）。hook-protocol 合并成员上的两个误加的 `@mode emit` 标签已被移除——新门禁将它们作为类别错误拒绝。
+
+## 曾考虑的替代方案
+
+- **基于启动的生成器（类似工具目录）**：日志词汇完全是静态的，AST 遍历无需启动任何东西即可读取全部真相。
+- **保留手工副本**：手工副本只能检查作者已经写下的名称；目录落地时，会话 README 的合并说明已经漂移。
+
+## 后果
+
+- 目录不会发生漂移：提交文件未反映的词汇或信封变化会使 `doc-sync` 和 CI 中的 `verify-persistence-catalog` 失败，而没有 JSDoc 的新增合并事件会直接使生成器失败——插件不能再添加未记录的磁盘记录类型。
+- 事件正文只有一个归属，即声明处的 JSDoc；目录会保留该 JSDoc 和所有嵌套字段注释，不会将其扁平化或复述。
+- `SurfaceEventType` union 现在对文档具有结构性承载作用：重命名事件而不更新 union（或反过来）会导致生成器失败，而不仅仅是编译器失败。
+- 徽章派生假设 union 始终是一组封闭的字符串字面量且只有一个拥有方；如果重构偏离了这一形状，必须在同一个变更中更新生成器。

## Problem
Agent Note paths encoded lifecycle and class, but file contents still mixed headings, status formats, ADR and proposal templates, and proposal-era sections in implemented records. Authors copied whichever neighbor they found, and lifecycle moves could skip the required rewrite because no gate enforced an in-file contract.

+# Agent Note: Agent Note 的统一受门禁约束的文件内格式
+
+Status: implemented
+
+[English](2026-07-05-uniform-agent-note-format.md) | 中文
+
+## 问题
+
+Agent Note（agent 决策记录）的路径编码了生命周期和类别，但文件内容仍混杂着不同标题、状态格式、ADR 与提案模板，以及已实现记录中的提案阶段章节。作者会复制随手找到的相邻文件，而生命周期迁移可能跳过必要的改写，因为没有门禁强制执行文件内契约。
+
+## 决策
+
+[README.md § 文件格式](../../README.md#the-file-format)是文件内契约——头部块（`# Agent Note: <title>`，加上无日期且与文件夹一致的 `Status:` 枚举，其中只有拒绝原因可作为额外内容）、各生命周期的正文骨架（所有文件均以 `Problem` 开篇；`proposed/` 使用 `Proposal`/`Acceptance criteria`/`Risks`；`implemented/` 使用现在时的 `Decision`/`Consequences`，并禁止提案阶段标题；`rejected/` 冻结提案形状）、强制的 `Alternatives considered` 章节，以及规范章节词汇；定制技术章节可在这些规范章节之间保持自由形式。`pnpm run verify-agent-note-format`（[scripts/verify-agent-note-format.ts](../../../../scripts/verify-agent-note-format.ts)）作为 `doc-sync` 的一部分强制执行每项机械规则，因此跳过改写的生命周期迁移现在会使 CI 失败，而不再依赖评审者记忆。
+
+定义该格式的同一变更规范化了整个语料库——遵循预发布立场：不设过渡期，不容忍双格式。唯一受既有条款豁免的是内容，而非格式：替代方案只能记录、不能杜撰，因此若某份格式制定前的 Agent Note 无法从记录中还原替代方案，就会携带确切的 `agent-note-format: alternatives-not-recorded` 注释；门禁只对日期早于本文的文件接受该注释。
+
+## 曾考虑的替代方案
+
+- **完整的刚性模板**（每个生命周期使用固定章节顺序，重构每份 Agent Note 以适配）：否决。大型设计 Agent Note 包含八到十五个定制技术章节（包（package）拓扑、线协议、schema），它们是承载设计的内容，而非漂移；刚性顺序会迫使我们现在进行破坏性改写，并永远与模板较劲。
+- **仅规范化头部**（H1 和 Status，正文不动）：否决。债务标记指出的是*正文*的体裁分裂，让 `Context`/`Decision` 与 `Problem`/`Proposal` 无限期并存什么也解决不了。
+- **不设 Status 行**（文件夹已经表示状态；格式制定前最新的三份 Agent Note 及其中一份的中文对应文件省略了该行）：否决，保留文件的自描述性。通过门禁校验该行与文件夹一致，消除了原本促使我们删除它的漂移风险。
+- **带日期的 Status**（`Status: implemented (accepted YYYY-MM-DD)`）：否决。接受日期属于叙述性历史，写作规则将其排除在文档之外；文件名承载首次提出日期，git 承载其余信息；门禁能检查日期格式，但永远无法检查其真实性。
+- **裸 `# <title>` H1**：否决。文件脱离目录树单独阅读时，`Agent Note: ` 前缀能自描述其体裁，而格式门禁可防止它漂移。
+- **以 `## What we give up` 作为已实现记录的结尾**（README 对 Agent Note 所记录内容的原有表述）：否决。它只点出成本，而诚实的后果章节也会记录取舍换来了什么。
+- **只有约定没有门禁**（写下契约，靠评审强制执行）：否决。slop checklist 已经通过约定禁止在 `implemented/` 中使用 spec 语气，而十九个文件展示了仅靠约定在此处能达到什么效果。
+- **独立的 `FORMAT.md` 契约文件**：否决。由一个入口同时承载布局、分类和格式，比维护两个契约文件更易发现和维护。
+
+## 后果
+
+现在每份 Agent Note 都需要稍多一些结构，而强制的 `Alternatives considered` 章节是有意设置的阻力：记录决策却不记录它胜过什么，会招致 Agent Note 本应防止的重新争论。无法还原替代方案的格式制定前 Agent Note 会永久保留既有条款注释——这是记录中诚实的缺口，而不是杜撰的理由。`doc-sync` 增加一道门禁；在生命周期文件夹之间移动 Agent Note 时，现在必须当场完成真正的工作（迁移本就应包含的正文改写），而不是推迟为无人跟踪的清理任务。三十九个债务标记已经消失，由它们一直等待的模板解决。

## Problem
The [cordis JSDoc completeness gate](2026-07-04-cordis-jsdoc-completeness-gate.md) made undocumented parameters and results impossible on the cordis surface — `interface Events` members and `ctx.<key>` service classes — but that surface is a fraction of what a plugin author imports. The AGENTS.md rule "every export (and non-obvious method) has a JSDoc explaining semantics" stayed prose-checkable only by review everywhere else, and nothing at all asked for `@param`/`@returns` on ordinary exported functions. A survey at adoption found 203 under-documented module-level exports across 34 packages: seam-adjacent helpers (`runBash`, `readForEdit`, `htmlToMarkdown`), format codecs, whole undocumented interfaces and type aliases — exactly the names an IDE consumer hovers.

+# Agent Note: 导出表面 JSDoc 门禁
+
+Status: implemented
+
+[English](2026-07-06-export-surface-jsdoc-gate.md) | 中文
+
+## 问题
+
+[Cordis JSDoc 完整性门禁](2026-07-04-cordis-jsdoc-completeness-gate.md)使得 Cordis 表面上的参数和返回值不可能缺少文档——`interface Events` 成员和 `ctx.<key>` 服务类——但这只是插件作者所导入内容的一小部分。AGENTS.md 中的规则「每个导出（以及非显而易见的方法）都必须有解释语义的 JSDoc」在其他地方只能靠评审以行文方式检查，而且没有任何机制要求普通导出函数带 `@param`/`@returns`。采纳时的一次调查发现 34 个包（package）中有 203 个文档不完整的模块级导出：seam 相关辅助函数（`runBash`、`readForEdit`、`htmlToMarkdown`）、格式编解码器、完全无文档的接口和类型别名——恰恰是 IDE 消费方悬停查看的那些名称。
+
+## 决策
+
+新增门禁 `scripts/verify-export-jsdoc.ts`（`pnpm run verify-export-jsdoc`，接入 `doc-sync`（文档同步门禁），与 `verify-cordis-catalog` 并列），遍历每个 `packages/<group>/<pkg>/src/` 目录树下的所有模块级导出名称。解析与检查辅助函数从 `gen-cordis-catalog.ts` 移入共享的 `scripts/jsdoc.ts`，使得「已文档化」在两个表面上含义一致：描述性文字在第一个块标签处截止、每个可检查参数需要非空 `@param`、非 void 且有显式标注的返回值需要非空 `@returns`、过时的 `@param` 报错，违规项汇总为一份报告。
+
+按声明类型划分的契约：
+
+- 每个导出名称都需要带有非空描述文字的 JSDoc。
+- 函数类导出（函数声明；初始化器为函数或带有内联可调用标注的 const；非标识符的函数默认导出）遵循完整的函数契约，分类前会剥离包装表达式（括号、`as`/`satisfies` 类型断言、非空断言）。如果 const 声明器标注了一个具名类型（`export const f: Handler = …`），签名契约推迟到该类型自身的声明处，`@returns` 保持可选；内联的 `(x: T) => U` 标注或单调用签名字面量本身就是表面签名，适用完整契约；而混合了调用/构造签名与其他成员的字面量则直接拒绝（没有单一签名可供标签对照——请提取具名类型）。
+- 导出类需要类级别的描述文字；公开方法（包括静态方法——可通过导出名称访问）遵循函数契约；公开属性和访问器需要描述文字（get/set 对由 getter 覆盖）。重载实现体免检——签名承载文档。
+- 导出接口、类型别名和枚举需要声明级别的描述文字；成员级别的强制有意推迟（承载关键成员契约的 seam 服务类已在 Cordis 门禁之下）。
+- 导出命名空间递归检查（在 ambient `declare` 命名空间内，每个成员隐式导出）；命名空间本身仅在不与同名的已文档化声明合并时才需要描述文字（Config-namespace 惯用法只需文档化插件一次）。
+- `declare module`/`declare global` 体和 `export … from` 重导出语句被跳过：augmentation 不是包的导出，重导出的定义在其定义处检查。`export import X = N.member` 别名需要文档化自身——其目标可能是遍历不会访问的非导出命名空间成员——且门禁仅支持纯描述文字的目标类型：可调用、类或命名空间目标携带别名描述文字无法承载的签名/成员契约，门禁会拒绝并要求直接导出该声明。
+- 其余情况按封闭原则失败：`export =` 直接拒绝；基类从未命名的参数即使作为绑定模式仍需 `@param`；dispatch 不识别的导出语句类型本身就是违规——没有任何导出形式能因遗漏而免检。
+
+三类豁免避免门禁要求样板代码，精神与 Cordis 门禁的 `this`/`next` 豁免一致（为已豁免的名称编写文档是允许的；只有缺失才不被检查）：
+
+- **继承成员。** 重写从其基类声明继承文档。新增的公开表面仍需文档：新增参数、将 protected 成员公开重写、或在 void 基类之上返回具体类型。继承查找和推断返回值分类是门禁唯一需要类型检查器的工作；其他检查使用 AST。
+- **插件协议槽位。** 顶层的 `name`/`inject`/`reusable`/`Config` 常量和 `apply` 入口，以及插件类上的同名静态成员，属于框架协议：其形状由 Cordis 固定，模块文档注释加 `interface Config` 承载插件的真实语义。
+- **构造函数**，与 Cordis 门禁一致：插件类由框架构造，类文档承载全部说明。
+
+`collectExportJsdocViolations()` 返回违规列表（CLI（命令行界面）在非空时以 1 退出），因此 `packages/core/agent/tests/verify-export-jsdoc.spec.ts` 中的负路径测试直接断言发现项，通过 fixture（测试前置数据）包驱动每一种拒绝和每一种豁免。
+
+## 曾考虑的替代方案
+
+- **eslint-plugin-jsdoc**（`require-jsdoc`/`require-param`/`require-returns`）：覆盖了机械核心，但无法表达本仓库的契约。继承成员豁免需要跨包的类型解析，协议槽位和命名空间合并惯用法是 Cordis 特有的，而完整性语义（标签前描述文字、过时标签报错、汇总报告）已在 `scripts/jsdoc.ts` 中与 catalog 生成器共享。两套微妙不同的「已文档化」定义，正是本仓库「单一归属」规则所要防止的失败模式。
+- **扩展 `gen-cordis-catalog.ts`**：catalog 生成器渲染一个精选表面并守卫其新鲜度；仓库级遍历没有 catalog 可渲染。共享辅助函数、保持遍历独立，使每个门禁的职责清晰可读。
+- **强制接口/类型别名的成员文档**：推迟。这会使检查表面成倍增长，而这些成员大多是自描述的字段；承载关键成员契约的 seam 服务类已有门禁。如果评审中出现成员文档漂移再重新考虑。
+
+## 后果
+
+- 新导出不能在缺少文档的情况下落地：`verify-export-jsdoc` 会使 `doc-sync` 和 CI 失败。采纳时发现的 203 处缺口已在同一变更中补齐，因此门禁以绿色状态落地。
+- 导出函数必须标注返回类型（采纳时已全面满足，现在成为门禁依赖），并在 `@param` 需要命名参数时使用标识符参数。
+- seam 文档是权威的：实现从其继承链继承文档，值得保留在实现上的行为说明是补充，而非必需。
+- 门禁构建一个 `ts.Program`（约 6 秒）——唯一需要类型解析的文档门禁；在已编译文档片段的 `doc-sync` 内可以接受。
+- 协议槽位名称按约定保留在模块顶层；一个恰好命名为 `apply` 或 `Config` 的非协议导出将不被检查——已接受，记录于此。

+# Agent Note: 生成式插件配置目录
+
+Status: implemented
+
+[English](2026-07-06-generated-config-catalog.md) | 中文
+
+## 问题
+
+仓库此前没有以源码为后盾的插件配置参考。各包（package）的 README 对字段的记录方式不一致，未列举哪些包可被加载，也未校验运行时 schema 与声明的配置类型是否一致。
+
+## 决策
+
+`scripts/gen-config-catalog.ts` 根据各插件声明的 config 类型和 JSDoc 生成 [docs/config-catalog.md](../../../../docs/config-catalog.md)，并包含注入要求、被引用类型的链接和源码位置。包内类型会以传递方式纳入；workspace 类型和外部类型则会链接或点名。确定性的 `--write` 和 `--check` 模式使提交页面成为生成产物。
+
+此处采用纯 AST 生成是正确的，原因与事件/服务目录相同，而与工具目录不同：配置类型是静态声明，仓库中每个 schemastery schema 都是静态的 `z.object`/`z.intersect` 字面量，因此源码即全部真相——配置表面没有任何部分是运行时组合的。
+
+具体选择：
+
+- **配置类型是第二参数的类型。** catalog 记录的是 `apply(ctx, config)` / 服务构造函数 `(ctx, config)` 的声明参数类型——即 Cordis 实际传入的值——而非按命名约定定位的 `Config` 导出。这使得遍历是全量的：无论接口叫 `AcpConfig` 还是 `BasicCompactConfig`，无论类型声明在兄弟文件中，还是插件完全没有验证 schema，都能正常工作。
+- **分类是全量的。** 每个 `packages/<group>/<pkg>` 条目都会被解析（镜像 Loader 的 `unwrapExports`：`exports.default ?? exports`），归入可配置插件、无配置插件、抽象 seam 类或库之一——各自渲染在独立小节中——无法归类的条目直接报错。新包不可能被悄悄遗漏。
+- **逐字段 JSDoc 强制要求。** 粘贴的声明中每个属性（包括嵌套的类型字面量）都需要非空的 JSDoc 描述，否则生成失败。粘贴本身就是文档，因此这与 events catalog 通过 `@mode` 施加的强制函数相同：源码文档过于单薄时门禁报错，而非产出单薄的 catalog。
+- **Schema 键与声明类型做比对。** 生成器通过局部和 workspace 类型解析嵌套的对象与数组路径。确定缺失的路径报错；无法枚举的外部或动态形状则跳过。比对有意设计为单向的，因为声明类型可能包含被排除在 loader 配置之外的运行时专用字段。
+- **专用围栏。** 粘贴的声明使用 ` ```ts config-catalog ` 信息字符串，`doc-typecheck` 会跳过它（引用了导入类型的孤立声明无法独立编译），并将其排除在 opt-out 比例之外——与 `cordis-catalog` 和 `persistence-catalog` 围栏的处理方式相同。
+- **单文件 `docs/config-catalog.md`**，而非一个单文件目录：该页面面向单一受众（`cordis.yml` 的编写者），只有一个维度，不同于 `cordis-catalog/`（其中包含两个并列页面）。
+
+各包 README 中的 `## Config` 小节保留。重叠是有意接受的：README 是经过策划的逐包契约（在部署上下文中描述配置语义，连同限制与扩展点），catalog 则是穷举式的生成枚举。由于 catalog 是生成的，二者不一致时说明 README 有误，修复方式是编辑 README——catalog 不会漂移。
+
+## 曾考虑的替代方案
+
+- **合成式逐字段渲染**：为每个字段生成项目符号列表、表格或带注释的 YAML 片段，从解析的 JSDoc 加 schema 元数据组装。否决，改用逐字粘贴：接口连同其 JSDoc 本身就是以原始形式撰写的契约，合成渲染器会重新格式化它不拥有的行文，增加一个可能歪曲原意的渲染层。
+- **运行时启动 + schema 内省（如工具目录所做的那样）**：否决。此处没有任何内容是运行时组合的，且 schema 本身对配置表面的文档化不足（以行文记录的默认值、运行时专用字段、完全没有 schema 的插件）。启动只会增加脆弱性而不增加真相。
+- **双向 schema/接口等价检查**：否决，改用子集检查。声明类型合理地包含 schema 拒绝从配置接受的成员（运行时专用 seam）。
+- **在同一变更中废除 README `## Config` 小节**：否决。保留可接受的重叠使逐包契约在原处可读，而清理工作需要先把每个 README 的额外事实折入字段 JSDoc——这是可分离的工作，catalog 不依赖它。
+
+## 后果
+
+- 目录不会发生漂移：提交文件未反映的源码变化会使 `doc-sync` 和 CI 中的 `verify-config-catalog` 失败。config 字段未记录、被引用类型名无法解析，或 schema 键未出现在 config 类型中，都会直接使生成器失败。
+- 配置行文现在有了声明处的强制函数：编写新配置字段意味着编写其 JSDoc，而该 JSDoc 将逐字成为 catalog 条目。
+- 生成器对无法静态遍历的形状直接报错——别名化的包内配置导入、非 `object`/`intersect` 组合构建的 schema、未列入的全局类型名。引入此类形状时必须同时教会生成器（否则该形状不能进入仓库），这正是设计意图：catalog 始终是全部真相。
+- `gen-cordis-catalog.ts` 导出其 JSDoc/指针辅助函数与 `LINK_MAP` 供复用，因此两个 catalog 以相同方式交叉链接类型，新增一条 link-map 条目同时服务于两者。

## Problem
The Node 22 branch of the root `engines.node` range is a contract for the installed workspace, not only for the runtime APIs the harness source calls directly. It must be no lower than package `engines.node` declarations for dependencies the workspace installs on that branch; otherwise `pnpm install --engine-strict` fails at an advertised LTS version, and non-strict installs run outside a dependency's supported runtime.

+# Agent Note: 将 Node LTS 引擎下限提升至 22.19
+
+Status: implemented
+
+[English](2026-07-06-node-engine-floor.md) | 中文
+
+## 问题
+
+根 `engines.node` 范围中的 Node 22 分支是对已安装工作区的契约，而不仅仅是 harness 源码直接调用的运行时 API 的契约。它不得低于工作区在该分支上安装的依赖包（package）所声明的 `engines.node`；否则 `pnpm install --engine-strict` 会在一个已宣传的 LTS 版本上失败，而非严格模式的安装则会在依赖所支持的运行时范围之外运行。
+
+## 决策
+
+将 `engines.node` 设为 `^22.19.0 || >=24.0.0`，并在 keyless CI 兼容性矩阵中测试 `['22.19', 24, 26]`。每条矩阵分支都运行 TypeScript 类型检查加一次 keyless 的源码模式 worker 冒烟测试，因此引擎下限通过完整的源码类型检查和真实的未构建运行时路径两条路径得到验证。真实 API 的 e2e 工作流保持在 Node 24 上，因为它验证的是 API 集成而非运行时下限。
+
+两个 Node 特性决定了源码运行时的门槛：
+
+- **`node:sqlite`**：`packages/session-persistence/session-persistence-sqlite` 在顶层执行 `import { DatabaseSync } from 'node:sqlite'`。该模块在 **22.13**（LTS）和 **23.4**（Current）取消了 `--experimental-sqlite` 标志要求；在此之前，导入它会在加载时抛出异常。
+- **原生 TypeScript 类型剥离**——构建模式的 `examples/headless-agent/tests/keyless-smoke.e2e.ts` 冒烟测试使用纯 `node`（无 tsx）启动 `dsh-cli-demo` 已发布的 `lib/bin.js`，并加载示例的 `.ts` 测试适配器（`cli-mock-llm.ts`）。类型剥离从 **22.18**（LTS）和 **23.6**（Current）起成为默认行为；更早版本需要 `--experimental-strip-types`。
+
+这些源码特性在 22.x 线上于 **22.18** 全部就绪，但已安装的 Pi 适配器依赖将宣传的 LTS 下限进一步提高。`@deepseek-ai/dsh-llm-pi-ai` 依赖 `@earendil-works/pi-ai@0.79.3`，后者的包声明 `engines.node >=22.19.0`，因此 LTS 下限为 **22.19**。24.x 分支保持 `>=24.0.0`。该不相交范围完全排除了 Node 23：Node 23.0–23.5 至少还有一个源码特性需要标志，而 23 线是非 LTS/已 EOL 的，宣传 `>=23.6` 会增加一条已终止的发布线和一条 CI 分支，而没有任何部署应当使用它。
+
+`@types/node` 继续固定在 22.x 线（`^22.20.0`），以匹配 LTS 支持线：使用 Node 23+/24+/25+ 的 API 会在所有机器和类型检查门禁中导致 `tsc` 失败，而不是编译通过、直到仅下限矩阵分支才能捕获的运行时错误才暴露。目前整个代码树在 Node 22 类型表面上类型检查全部通过，因此这一固定没有任何代价。
+
+## 后果
+
+- 宣传的 LTS 分支不再低于 Pi 适配器依赖的下限。
+- CI 通过 Node 22.19 直接验证 Node 22 LTS 下限，Node 24 分支保持 `node: 24`，Node 26 用于下一个偶数线；每条分支都对源码图执行类型检查，并实际启动未构建的工作流 worker。
+- built-bin 冒烟测试无需版本条件标志：在 22.19 上类型剥离已是默认行为，因此测试保持其文档所述的纯 `node lib/bin.js` 路径。
+- 未来若依赖或源码 API 提高运行时下限，必须在同一变更中同步调整 `engines.node`、兼容性矩阵和本 Agent Note（agent 决策记录）。
+
+## 曾考虑的替代方案
+
+- **保持 `^22.18.0 || >=24.0.0`。** 否决：它宣传的 LTS 版本低于 Pi 适配器依赖的下限。`@earendil-works/pi-ai@0.79.3` 要求 `>=22.19.0`。
+- **降级或固定 `@earendil-works/pi-ai` 以保留 22.18 的宣传范围。** 否决：当前 Pi 适配器依赖是预期工作区的一部分，且 22.19 仍在 Node 22 LTS 线内。
+- **下限 `>=22.13`（`node:sqlite` 边界）加上在 22.13–22.17 的 built-bin 冒烟测试中使用 `--experimental-strip-types`。** 否决：它为一个狭窄范围增加了版本条件测试标志，并将实验性标志依赖包装为正式支持。Pi 适配器依赖已经要求更高的 LTS 下限。
+- **开放式 `>=22.19`。** 否决：它宣传支持 Node 23.0–23.5，而在这些版本上 `node:sqlite`（直到 23.4）或类型剥离（直到 23.6）仍需标志。
+- **包含 Node 23.6+（`^22.19.0 || >=23.6.0`）。** 否决：23.6+ 确实能无标志运行两个源码特性，但 Node 23 已 end-of-life；宣传一条已终止的发布线会增加一个范围项和一条 CI 分支，而没有任何部署应当使用该运行时。
+- **矩阵 `[22, 24, 26]` 而非固定 `22.19`。** 否决：浮动的主版本号条目会随时间上漂，悄然不再验证所声明的 LTS 下限。
+- **保持 `@types/node` 超前于运行时下限（`^25`）。** 否决：类型定义超前于运行时下限会让仅 Node 24/25 才有的 API 编译通过，仅在 22.x 上运行时才失败。将 `@types/node` 固定在 22.x 线上可将此类问题转化为所有环境下的编译错误。

-# Agent Note: Parallel GitHub CI gates
-
-Status: implemented
-
-## Problem
-
-The keyless GitHub CI gates are mostly orthogonal: typecheck, lint, documentation freshness, coverage, snapshot replay, build, package-publication hygiene, demo smoke, and built-bin smoke fail for different reasons and do not need each other's runtime state. Running them as one ordered command chain makes the workflow wall clock equal the sum of those gates, while splitting every short leaf into its own GitHub job repeats checkout, Node setup, pnpm restore, and install work until orchestration overhead becomes the bottleneck.
-
-The original broad-lane split stopped meeting that balance as the workspace grew. On the merge of PR #404, Linux static, coverage, snapshot, and artifact jobs took 148, 195, 94, and 230 seconds; Windows static and artifacts took 251 and 482 seconds. Package-manager packing once per package dominated both artifact validators, coverage needlessly rebuilt output before a source-only suite, and CPU-heavy gates contended inside the static and coverage lanes.
-
-The artifact boundary remains load-bearing. `publint`, `verify-node-next-types`, compiled invariant loading, and built-bin smoke tests need emitted `lib/` output. Sharding cannot race those consumers ahead of build or replace their published-artifact signal with source execution.
-
-## Decision
-
-The production topology below is historical and is superseded by [Evidence-based larger hosted runners](2026-07-22-evidence-based-larger-hosted-runners.md). The larger-runner decision removes its shard selectors and workflow jobs; this note preserves why that earlier topology was implemented.
-
-[CI](../../../../.github/workflows/ci.yml) treats one minute for non-Windows jobs and three minutes for Windows jobs as observed performance targets, not cancellation deadlines. Hosted-runner variance should leave complete timing evidence and useful failure logs instead of cancelling an otherwise-correct gate. The [serial cross-platform CI reference](2026-07-21-serial-cross-platform-ci-reference.md) independently runs the complete unsharded primary Node aggregate on Linux, macOS, and Windows so the optimized lane inventory is not its own completeness oracle.
-
-In that topology, [scripts/run-gates.ts](../../../../scripts/run-gates.ts) was the common bounded scheduler and GitHub supplied explicit shard names for the expensive gate families. `scripts/static-shards.ts` partitioned static gates into foundation, documentation-type, API-contract, catalog, prose, documentation-projection, and documentation-build ownership and rejected a missing or duplicate gate assignment. Linux lint used disjoint A-C, D-M, N-S, and T-Z package-source and package-test lanes, while Windows used complete package-source and package-test lanes; both included a repository complement starting from `.` so new top-level targets could not disappear between shards and owned the single cross-file duplication run. `scripts/coverage-shards.ts` assigned every workspace package to exactly one source-coverage lane. Directory filters retained a trailing separator because Vitest positional filters match substrings and would otherwise admit prefix-named siblings. Each coverage lane included only its owned source files, repeated the exhaustive companion topology test, and ran without a preceding build because the complete coverage suite passes from a tree with every generated `lib/` removed.
-
-Snapshot replay used two explicit multi-file lanes and eight scenario partitions of the large ACP file. `scripts/snapshot-shards.ts` owned that inventory, and its test discovered every file admitted by the snapshot config. Each snapshot job installed dependencies while its Linux runner prepared Bubblewrap, built the shipped runtime, and ran only its assigned replay surface. The suite retained bounded concurrency of five subprocesses because replay spent most of its time waiting on child protocol I/O. Fixture guards still inspected the complete ACP scenario table in every partition.
-
-Cold standalone documentation typechecking rebuilds the complete project-reference graph, so a dedicated documentation-type lane builds once and checks Markdown blocks against those declarations. The Linux documentation lane uses VitePress's MPA build to retain page rendering and dead-link validation within the observed non-Windows target; separate blocking Windows build and production-site lanes preserve the emitted-package and shipped-site checks without putting both critical paths in one job.
-
-Artifacts use two lanes: one metadata lane for `publint`, NodeNext declarations, and compiled invariant loading, plus one built-bin smoke lane. Each lane produces its own build before its consumers. Repeating the short build costs runner minutes but avoids an upload/download dependency and keeps each job's critical path bounded.
-
-[scripts/publint-all.ts](../../../../scripts/publint-all.ts) calls publint's supported API in-process against an in-memory publication view made from each manifest's declared files and npm's mandatory metadata files. This preserves the distinction between workspace files and published files without spawning a package-manager pack command 103 times. [scripts/verify-built-package-invariants.mjs](../../../../scripts/verify-built-package-invariants.mjs) stages those structurally validated manifest-declared `lib/` files below the real package, then imports the compiled self-reference through plain Node and Cordis Loader normalization. A companion that reaches an undeclared runtime chunk still fails.
-
-Compatibility lanes run the source worker and Zstandard runtime smokes on every advertised Node line. TypeScript checks the source graph once in a dedicated primary Node 24 lane; repeating the same compiler analysis in runtime compatibility jobs added time without runtime-specific signal.
-
-The workflow caches the pnpm store, keys each immutable ESLint cache to its owning lint shard, preserves native PowerShell for Windows measurements, and retains one aggregate `all checks passed` status for branch protection. Windows reuses the three exhaustive lint partitions and groups foundation/catalog/prose plus documentation-type/API-contract gates behind shared runner setups; only scheduling differs from the Linux partitions. Windows build and production-site validation remain blocking, while the wider Windows static, lint, and artifact matrix remains observational.
-
-## Alternatives considered
-
-- **Keep the broad lanes** - minimizes workflow YAML, but it preserves the measured multi-minute feedback loop.
-- **Run every leaf gate as a separate GitHub job** - maximizes fan-out, but short generators and prose checks would spend more time preparing a runner than checking the repository.
-- **Upload one build to artifact consumers** - avoids repeated compilation, but upload/download and dependency scheduling lengthen wall time; the clean build is short enough to repeat inside bounded lanes.
-- **Keep package-manager packing in both publication gates** - delegates inventory selection to pnpm, but repeats more than 200 package-manager processes. The manifest structural gate plus publication-view fixtures make the optimized inventory contract explicit and fail on an on-disk but unpublished dependency.
-- **Keep build before coverage** - provides emitted output the source suite no longer consumes; a clean-tree coverage proof showed it was pure latency.
-- **Typecheck on every Node version** - repeats compiler work while the compatibility smokes already exercise actual Node-specific loading and compression behavior.
-
-## Consequences
-
-The shard inventories and matrix jobs described above are not part of the current repository contract. The superseding larger-runner decision keeps the complete primary inventory in one process and uses the serial suite as its independent completeness oracle.
-
-The optimized publication validators rely on the manifest `files` contract enforced by `verify-package-invariants`. If publication rules grow beyond that contract, the structural gate and both staged views must change together.
-
-Compatibility jobs no longer claim that TypeScript itself was exercised under every Node runtime. They prove runtime-sensitive source loading on Node 22, 24, and 26, while the primary runtime owns the single source-graph typecheck.

+# Agent Note: 并行 pre-push 门禁
+
+Status: implemented
+
+[English](2026-07-06-parallel-pre-push-gates.md) | 中文
+
+本记录中的本地 hook 部分已由[快速本地 Git hook](2026-07-22-fast-local-git-hooks.md) 取代。有界门禁调度器和包（package）级 `publint` 并行机制仍用于 CI、`doc-sync` 和显式本地命令。
+
+## 问题
+
+文档同步等聚合 job 隐藏了很长的串行链，其成员只读且相互独立。在工作流 YAML 中重复这些叶子清单，会使未来脚本变更有多个位置可以发生漂移；而串行运行包发布检查，会使一道门禁的耗时与包数量成正比。
+
+## 决策
+
+[scripts/run-gates.ts](../../../../scripts/run-gates.ts) 拥有 CI、`doc-sync` 和选择启用的 `check:all` 命令所使用的有界调度器。它将具名模式展开为叶子门禁，遵守产物依赖，缓冲可归因的输出，并在调用方需要不同 worker 上限时接受 `DSH_GATE_CONCURRENCY`。
+
+[scripts/publint-all.ts](../../../../scripts/publint-all.ts) 从 `packages/<group>/<pkg>` 发现包，并以根据 `availableParallelism()` 确定大小的 worker 池运行 `publint`。`DSH_PUBLINT_CONCURRENCY` 可以针对资源配置不同的本地机器和 CI runner 限制或提高 worker 数量。结果按包缓冲，并按确定性的包顺序打印，因此并行执行不会打乱各包的日志块。
+
+各门禁的包脚本仍是临时本地运行所用的词汇。`hygiene` 继续作为聚合 `&&` 链，而 `doc-sync` 在调度器中拥有其成员列表（[通过门禁调度器运行 doc-sync](2026-07-21-doc-sync-through-gate-scheduler.md)）。
+
+## 曾考虑的替代方案
+
+- **保持聚合 job 串行**：执行更简单，但墙钟时间等于各独立检查之和，并重复启动命令包装器。
+- **每个叶子门禁声明一个 CI job**：暴露最大工作流并行度，但会重复 checkout、设置和安装开销，并在 YAML 中复制调度器清单。
+- **在 shell 脚本内后台运行子命令**：可以并行处理，但会失去各门禁计时、确定性的失败分组和直接的信号处理。
+- **每个包声明一个 `publint` job**：暴露最大包级并行度，但会创建手工维护的包清单，包发生变化时就会漂移。
+- **以无界并发运行 `publint`**：只有通过拿进程数、内存压力、包 tarball 创建和可读日志冒险，才能最大限度缩短小型仓库的耗时。
+
+## 后果
+
+由调度器支持的命令耗时取最慢依赖链，而非各独立门禁之和，并会报告主导耗时的门禁。代价是维护一个具有显式模式清单的定制调度器。
+
+`publint-all.ts` 采用异步执行并缓冲命令输出，而不是实时继承 stdio。换来的是具有稳定输出顺序的包级并行，以及用于资源调节的单一环境变量。

+如果一个包确实没有需要声明的限制事项，则将其列入 `NO_LIMITATIONS` 并省略该章节。新增限制事项时须移除该条目；重命名或移除条目会失败，因为每个条目都必须对应一个被扫描的包。

+- **设置字数上限**：合理的限制事项数量因包而异，因此由评审管控这一不设预算的 README 层级。
+
+## 后果

## Problem
A package README can explain APIs and runtime mechanics without answering the questions that dominate an agent harness's behavior and cost: what from this package reaches a model request, under which conditions, how long those tokens remain, and whether later requests preserve a reusable KV-cache prefix. The omission is especially hard to audit in a plugin architecture. A consumer may turn a backend result into a tool message, a policy plugin may replace success with an error, compaction may remove old history, and an agent-scoped registration may change one agent's prompt or schemas while leaving every other agent unchanged. Reading only the nominally model-facing packages therefore misses real context effects, while reading source across every dependency is too expensive for routine review.

+# Agent Note: 包（package）的模型体验契约
+
+Status: implemented
+
+[English](2026-07-12-package-model-experience-contract.md) | 中文
+
+## 问题
+
+包 README 可以解释 API 和运行时机制，却不回答主导 agent harness（智能体框架）行为与成本的问题：该包的哪些内容会进入模型请求、在什么条件下进入、这些 token 会保留多久，以及后续请求是否会保留可复用的 KV cache 前缀。在插件架构中，这种遗漏尤其难以审计。消费方可能把后端结果转为工具消息，策略插件可能以错误取代成功结果，压缩可能移除旧历史，而 agent 范围的注册可能改变某个 agent 的提示词或 schema，却不影响其他 agent。因此，只阅读名义上面向模型的包会遗漏真实的上下文效应，而在每次常规评审中跨所有依赖阅读源码又成本过高。
+
+## 决策
+
+每个具有面向模型或邻近模型契约的 workspace 包 README 都以规范的[模型体验章节](../../../../docs/cookbook/adding-a-package.md#4-write-the-package-readme)收尾，位置紧邻 `## Known Limitations and Deferred Work` 之前；位于“无限制项”允许列表中的包则以模型体验本身结尾。经审计确认与模型无关的通用包通过 `NO_MODEL_EXPERIENCE_SECTION` 省略该章节。
+
+具有直接、条件式、有上限、全生命周期、多表面或辅助模型效应的包，为每个上下文表面使用一个 H3。每个表面包含三个有序 H4 字段——`What the model sees`、`Token effect` 和 `KV Cache effect`——每个字段都以一个正文段落开头。cache 字段区分仅追加增长、稳定重复前缀、替换先前 token，以及独立模型请求；它点明由包拥有、且能在新内容追加前改变请求的每项配置、范围、生命周期、压缩或路由变化。“Does not invalidate”表示该包保留一个已经可复用的前缀，并非承诺提供方一定命中 cache 或保留某段时间。由包拥有的稳定文本按原文精确引用：系统提示词正文和其他长字面量在引入它们的字段下使用带标题的 H5 加 `markdown` 围栏，通常位于 `What the model sees`；短字面量则以内联形式保留，并点名插值占位符。工具 schema 表面链接生成式[工具目录](../../../../docs/tool-catalog.md)中带锚点的章节，并且只陈述组合或配置增量；仅运行时定义解释目录为何省略它们。依赖数据和由提供方拥有的文本采用摘要。agent 范围的可见性须显式说明；当范围可隐藏提示词与 schema 中的一者而不影响另一者时，两种表面保持分离。
+
+没有模型上下文效应的包，或某条路径完全由另一个包渲染的包，使用验证器审计过的短格式：一句以 `None, as ` 或 `Indirectly, through ` 开头的句子，随后是一个 `KV Cache effect` H4 和一个正文段落。纯传输包和无密钥测试支持包若不创建任何进入模型的内容，就使用 none 格式。提供方后端即使会限制或过滤数据也使用 indirect 格式；具名子项拥有全部效应时，接线 bundle 也使用该格式。这些章节定位贡献并声明不会直接使 cache 失效，同时不重复陈述消费方。结构化章节同样只记录由包拥有的输入、变换和增量。
+
+`verify-package-readme-model-experience` 发现包清单，并验证三种分类、规范末尾章节顺序、确切字段标题深度与顺序、非空字段段落、逐字块的 H5 归属、具体字面量证据，以及带锚点的工具目录链接。它在 `doc-sync` 和并行门禁 runner 中运行。评审仍负责覆盖面、链接相关性和事实准确性。
+
+## 曾考虑的替代方案
+
+- **只记录注册提示词或工具的包**：否决。后端、策略插件、适配器、持久化、作用域和压缩都会改变 token 的内容或生命周期，却不拥有面向模型的 schema。
+- **从源码生成一份集中式上下文成本目录**：否决。AST 能找到注册点，但无法推断语义条件，如历史保留、输出截断、父子可见性或辅助模型边界。包 README 是实现本地的契约；集中副本会增加又一个漂移面。
+- **要求给出精确 token 数**：否决。精确数量取决于所选模型的 tokenizer、适配器序列化方式、配置和运行时数据。稳定的契约是增长形状：每请求固定、每调用条件性、保留、替换、有上限或零直接影响。
+- **使用表格**：否决。精确源码文本和条件式结果形状会使单元格密集而难以扫读。重复的小节在保留相同字段的同时，为每个上下文表面提供易读的纵向空间。
+- **允许所有零影响包省略该章节**：否决。无约束的缺失在「经审计的零影响」和「忘记写文档」之间有歧义。省略仅限于在验证器中以理由命名的模型无关通用包；模型相邻的零影响包保留一句显式说明。
+- **要求经审计的零效应包或简单间接包使用完整结构化格式**：否决。它会围绕一个事实重复标签。受门禁约束的句子加 cache 字段既保留显式覆盖，又没有多余仪式。
+- **只有约定而无门禁**：否决。仓库级契约必须覆盖未来的每个包；评审者的记忆无法可靠地检测到遗漏的 README 章节。
+
+## 后果
+
+评审者可以从任何面向模型或邻近模型的包开始，看到它对对话模型、子模型和辅助调用的贡献，无需重建完整插件图。token 预算工作可以区分重复请求开销和依赖数据的历史，而 cache 敏感工作可以识别仅追加路径，以及最早由包引起的前缀变更。agent 范围变更有明确的文档检查点。每当模型可见行为发生变化时，包作者都要维护一个或多个紧凑的上下文表面块，或一种已分类的短格式；经审计的通用包不携带无关的模型样板。结构化字段不承诺由提供方给出的精确 token 数或 cache 命中；测量仍取决于具体模型、提供方和工作负载，而所记录的增长、可见性和前缀稳定性契约保持稳定。

Updating the note that already owns a decision satisfies the rule; a new note is required only when no note owns it.

The [Agent Notes README](../../README.md#when-to-write-one) owns this boundary, while root `AGENTS.md` carries the standing order.
+A fully superseded implemented note may be consolidated into the current owning note and deleted only after that owner preserves every unique rationale, alternative, consequence, verification contract, and named coverage gap. The same change repairs inbound links and removes any Chinese counterpart, consistency record, and `required` entry in `scripts/translation-pairing.manifest.json`. Partial supersession keeps both notes cross-linked and current; consolidation neither rewrites an old decision into its opposite nor leaves git history as the only copy of rationale.

The removal owner preserves the feature's original motivation, why that motivation no longer justified the surface, alternatives to full removal, the capability given up, conditions for reintroduction, and verification of complete absence. Implementation inventories and tests that only described the deleted behavior are obsolete rather than current verification contracts.

**Require a new note for every change.** This duplicates an existing note when it already owns the decision and adds empty ceremony to purely mechanical edits.
+**Keep every fully superseded note indefinitely.** A cross-linked record is necessary while part of its decision remains current, but a wholly obsolete implemented note contradicts the current-state contract and duplicates rationale that can have one owner.

+**Add a `superseded/` lifecycle.** Another lifecycle would retain the obsolete record and expand the tree, format gate, and maintenance rules without reducing duplication.

- Every substantial change preserves its rationale and rejected alternatives beside the implementation.
- Contributors maintain an existing owning note instead of creating duplicate records.
+- Fully superseded records can collapse into one current owner without losing their unique rationale or verification contract.
+- Features that were later removed can have one current owner without carrying obsolete implementation and test inventories forward.
+- Partial supersession remains explicit and cross-linked, while deletion requires link, bilingual-pair, and required-manifest cleanup in the same change.
- Mechanical edits remain lightweight, and the gate topology and runtime remain unchanged.

Each reference job runs `pnpm run check:ci` without any shard selector. `DSH_GATE_CONCURRENCY=1` makes the top-level aggregate execute one ready gate at a time; coverage, snapshot replay, built-bin smoke, and publication validation also receive worker counts of one. The three operating-system jobs may run beside one another, but each host's repository gates are serial and complete. Linux installs bubblewrap before replaying snapshots, and Windows enables Developer Mode before installing the symlinked workspace.
+Platform ownership remains explicit inside that complete aggregate. `pty-local` supports Linux and macOS and therefore owns its unit and per-file coverage contract on POSIX rather than loading a backend that rejects `win32`; the Windows run still executes every portable package. Portable fixtures derive native paths through `node:path`, compare canonical identities with the same native realpath implementation as production, and use filenames legal on every host. ACP snapshot runs also pass both JavaScript and native realpath spellings of their generated cwd to the normalizer, which replaces aliases longest-first so Windows short and long paths cannot churn shared fixtures.
+
+The macOS reference runs the ordinary Vitest project in forked processes. Node 24 on macOS arm64 has aborted in its CJS lexer from a worker thread; the process boundary contains that external runtime failure without removing any test from the aggregate, while Linux and Windows retain the lower-overhead thread pool. Repository-owned races are fixed at their observation boundaries: dev bundle polling stages each candidate table, graph, and watch-baseline map before publishing a rescan, and a missing bundle remains dirty until a successful content hash. PTY readiness retains a prompt candidate while polling checks foreground ownership; the ordinary silence bound covers inherited markers from interactive children. The live-link package-manager e2e preserves the workflow-prepared Corepack home and pnpm metadata/store caches while isolating the other managers' mutable caches, so it does not discard reusable package-manager state before the install.

Master reference jobs are diagnostic and do not participate in the pull request's required `all checks passed` result. A pull request runs only its required jobs; a master push runs only the three serial references. Performance is evaluated from completed hosted-job timestamps and reported as a measurement; it is not encoded as a `timeout-minutes` value.
The portable reference uses GitHub's standard `ubuntu-latest`, `macos-latest`, and `windows-2025` labels. Required pull-request jobs use the same portable Linux and Windows capacity under the [required-CI decision](2026-07-23-portable-required-pull-request-ci.md). Higher-core hosted runners remain manual benchmarks because a correctness path must remain runnable without repository-external runner configuration.

The reference may expose platform failures that the optimized blocking set does not yet claim to support, especially on Windows. Such a failure is evidence about current cross-platform behavior rather than a reason to weaken or silently skip the aggregate.
+The explicit `pty-local` ownership boundary means Windows does not claim coverage for a backend it cannot load, and forked macOS unit workers cost more process startup time. In return, every supported surface has an honest platform oracle, a native runtime abort cannot erase the rest of the unit result, and timing-sensitive observers start from state established before callers can mutate it.

Removing strict duration timeouts means a latency regression is observed rather than automatically cancelled. Hosted measurements must therefore accompany performance changes, while the completed logs retain the information needed to optimize the slow lane.

Linux primary work uses three independent 32-core jobs. Coverage runs alone with its own worker bound, and the static scheduler runs alone so its result has no post-build consumer tail. After static gates finish, that job publishes its emitted `apps/*/lib`, `packages/*/*/lib`, and `vendor/*/lib` tree as a run-scoped artifact. The third job restores that exact tree, then starts lint, Node 24 runtime compatibility, build-backed snapshots, and all artifact consumers without repeating the build. Generated NodeNext consumer directories are excluded from ESLint discovery because the artifact check removes them while these processes overlap. The pnpm store and ESLint cache are restored without putting cache uploads on the pull-request critical path. Performance reports use each job's `startedAt` to `completedAt` interval; runner queue delay is capacity evidence, not repository execution time.
+The gate dependencies remain explicit. Coverage consumes source and does not wait for build. Documentation typechecking builds its complete project-reference graph once. Snapshot replay and publication consumers wait for emitted output, while Node-version compatibility jobs exercise runtime-sensitive source loading without repeating the primary source-graph typecheck. PTY and subprocess suites keep their bounded inner concurrency rather than inheriting the runner's core count.
+
+The artifact boundary remains explicit. `scripts/publint-all.ts` calls publint's supported API against an in-memory publication view formed from each manifest's declared files plus npm's mandatory metadata, avoiding one package-manager pack process per package. `scripts/verify-built-package-invariants.mjs` stages the declared `lib/` files below the real package and imports its compiled self-reference through plain Node and Cordis Loader normalization; a runtime chunk omitted from the publication contract still fails.
+
Windows shares one 32-core setup across the blocking build and production site plus observational built-artifact contracts. Linux owns the duplicate lint, coverage, and snapshot inventories because running those observational copies on Windows extends the paid critical path without adding a blocking platform claim.

+# Agent Note: Semantic pull request label taxonomy
+
+Status: implemented
+
+English | [中文](2026-07-25-semantic-pr-label-taxonomy.zh.md)
+
+## Problem
+
+Pull requests need two different signals: what kind of change they make and which repository domains they affect. A flat or broadly named label set conflates those questions, hides work in distinct areas such as `session` and `llm`, and gives reviewers and automation weak inputs.
+
+The repository also gains new domains over time. Treating today's area labels as a closed set would force future work into inaccurate labels or a generic catch-all.
+
+## Decision
+
+Every open or merged pull request carries exactly one kind and every materially affected area. Closed pull requests that were never merged are outside the maintained historical corpus. Other operational labels may coexist, but they do not satisfy either dimension.
+
+### Kinds
+
+| Kind | Meaning |
+|---|---|
+| `feature` | Adds or intentionally changes behavior. |
+| `bug-fix` | Corrects incorrect behavior. |
+| `doc` | Makes documentation the dominant intent. |
+| `testing` | Changes tests or testing infrastructure without changing product behavior. |
+| `cleanup` | Preserves behavior while maintaining or simplifying the implementation or repository process. |
+
+The kind records the change's dominant intent: accompanying tests and documentation do not turn a feature or bug fix into a testing or documentation change.
+
+Areas record semantic repository domains rather than temporary initiatives, ownership, or every path touched incidentally. Area labels are not a hierarchy: a pull request may carry several when it changes distinct contracts, but an umbrella and a narrower label do not both describe the same work.
+
+### Current areas
+
+The 45 current areas are listed below. The group names organize the list for readability; they are not labels or another taxonomy level.
+
+| Group | Areas |
+|---|---|
+| Agent and model | `agent`, `agent-loop`, `session`, `llm`, `model-context`, `compaction`, `tools`, `persistence` |
+| Orchestration | `subagent`, `workflow`, `planning`, `tasks`, `schedule`, `telemetry`, `storage`, `workspace` |
+| Capabilities | `bash`, `pty`, `filesystem`, `lsp`, `skills`, `web-search`, `code-mode`, `artifact`, `attachment`, `sandbox`, `mcp`, `hooks`, `cordis` |
+| Interfaces | `ui`, `gui`, `tui`, `acp`, `json-rpc`, `cli`, `python-sdk`, `vscode`, `website` |
+| Repository and release | `dev-infra`, `ci`, `build`, `dependencies`, `platform`, `i18n`, `release` |
+
+`gui` covers browser and Electron graphical applications, including standalone graphical developer tools; `vscode` remains the editor extension integration. `ui` covers shared cross-interface commands, approval interaction, presentation, and app boot; it coexists with `gui`, `tui`, or a protocol area only when the pull request also changes that shared contract.
+
+`tasks` owns background work tied to a running process, while `schedule` owns durable time-triggered jobs. `tools` owns generic registry, schema, and execution contracts; a concrete capability receives `tools` only when it changes one of those contracts. `attachment` owns durable media references and multimodal input delivery, while `artifact` owns model-declared deliverable identity and preview lifecycle; neither borrows `tools` or `ui` for its implementation parts.
+
+Names follow semantic ownership rather than lexical resemblance. `hooks` means the Claude Code and Codex agent bridges, not local Git hooks; `platform` means product portability, not CI runner selection; and `build` means compilation, bundling, and built package artifacts, not documentation generators.
+
+### Extensibility
+
+The area set is intentionally extensible. Add an area when a recurring, meaningful repository domain is missing; do not add a label for one pull request, a temporary project, a status, or a person or team. Rename, split, or retire an area when the domain model changes, and update this list and the affected open and merged pull requests together.
+
+The kind set stays narrow because kinds are mutually exclusive. A new kind requires a distinct change intent that cannot be represented by the current five; it is not a substitute for an area.
+
+## Alternatives considered
+
+- **One undifferentiated label set.** Rejected because kind and area answer different questions; mixing them makes the presence of one label say nothing about whether the other dimension was considered.
+- **A fixed, closed area set.** Rejected because repository domains evolve. A closed set would preserve spelling at the cost of semantic accuracy.
+- **One broad `core` area or package-derived labels.** Rejected because domains such as `session`, `llm`, and `agent` remain independently meaningful across package boundaries, while incidental file paths are not the scope reviewers or automation need.
+- **Separate browser and desktop areas.** Rejected because browser delivery and Electron packaging expose one graphical client domain; splitting them classifies the delivery shell rather than the semantic work.
+- **Broad implementation areas in place of a domain.** Rejected because a durable scheduled job is not a background task, an attachment is not merely its source interface or filesystem implementation, and an artifact is not merely its declaring tool or preview interface.
+- **Umbrella and leaf areas for the same contract.** Rejected because duplicate labels inflate scope without adding information. Multiple areas remain correct when a pull request changes genuinely distinct contracts.
+- **Exactly one area per pull request.** Rejected because coherent changes can legitimately span several domains, and dropping secondary areas hides affected contracts.
+
+## Consequences
+
+- Reviewers and automation receive one stable intent signal plus a complete semantic scope.
+- `gui` queries cover browser and desktop delivery together, while `ui` queries retain only shared cross-interface contracts.
+- `schedule`, `attachment`, and `artifact` queries identify those domains directly instead of approximating them through implementation dependencies.
+- Selecting labels remains a judgment call: paths and title prefixes can suggest areas, but they cannot replace reading the change.
+- Taxonomy changes carry maintenance work. Area additions, renames, splits, and removals update this decision record and backfill open and merged pull requests so historical queries keep their meaning.

+# Agent Note: 语义化 PR 标签分类体系
+
+Status: implemented
+
+[English](2026-07-25-semantic-pr-label-taxonomy.md) | 中文
+
+## 问题
+
+PR（Pull Request）需要传达两个不同的信号：它带来哪一类变更，以及会影响仓库中的哪些领域。一套扁平或命名宽泛的标签会混淆这两个问题，掩盖 `session`、`llm` 等不同领域的工作，也让评审人和自动化流程得到的输入缺乏有效信息。
+
+仓库还会随时间发展出新的领域。如果把当前的领域标签视为封闭集合，未来的工作就只能归入不准确的标签或通用兜底标签。
+
+## 决策
+
+每项开放或已合并的 PR 都带有恰好一个类型标签，以及所有受到实质影响的领域标签。未合并即关闭的 PR 不属于持续维护的历史记录集合。其他管理用途的标签可以并存，但都不能满足这两个维度中的任一个。
+
+### 类型
+
+| 类型 | 含义 |
+|---|---|
+| `feature` | 新增行为或有意改变行为。 |
+| `bug-fix` | 修正错误行为。 |
+| `doc` | 以文档变更为主要意图。 |
+| `testing` | 修改测试或测试基础设施，但不改变产品行为。 |
+| `cleanup` | 在保持行为不变的前提下，维护或简化实现或仓库流程。 |
+
+类型记录变更的主要意图：配套测试与文档并不会把一项功能或缺陷修复变成测试或文档变更。
+
+领域记录仓库中的语义领域，而不是临时项目、归属关系或偶然触及的每条路径。领域标签不构成层级：一项 PR 修改不同契约时可以带有多个领域标签，但不能用一个总括标签和一个较窄标签重复描述同一项工作。
+
+### 当前领域
+
+当前的 45 个领域如下。分组名称仅用于提高列表的可读性；它们既不是标签，也不是分类体系中的另一个层级。
+
+| 分组 | 领域 |
+|---|---|
+| agent（智能体）与模型 | `agent`, `agent-loop`, `session`, `llm`, `model-context`, `compaction`, `tools`, `persistence` |
+| 编排 | `subagent`, `workflow`, `planning`, `tasks`, `schedule`, `telemetry`, `storage`, `workspace` |
+| 能力 | `bash`, `pty`, `filesystem`, `lsp`, `skills`, `web-search`, `code-mode`, `artifact`, `attachment`, `sandbox`, `mcp`, `hooks`, `cordis` |
+| 接口 | `ui`, `gui`, `tui`, `acp`, `json-rpc`, `cli`, `python-sdk`, `vscode`, `website` |
+| 仓库与发布 | `dev-infra`, `ci`, `build`, `dependencies`, `platform`, `i18n`, `release` |
+
+`gui` 涵盖浏览器和 Electron 图形应用，包括独立的图形化开发者工具；`vscode` 仍表示编辑器扩展集成。`ui` 涵盖共享的跨接口命令、审批交互、呈现和应用启动；只有当 PR 还修改这项共享契约时，它才与 `gui`、`tui` 或某个协议领域并用。
+
+`tasks` 负责与运行中进程绑定的后台工作，`schedule` 则负责持久化的定时作业。`tools` 负责通用的注册表契约、schema 契约和执行契约；具体能力只有在修改其中一项契约时才带有 `tools`。`attachment` 负责持久化的媒体引用和多模态输入传递，`artifact` 则负责模型声明的交付物标识和预览生命周期；二者都不会因实现包含工具或界面部分而借用 `tools` 或 `ui`。
+
+标签名称以语义归属为准，而不是词面相似性。`hooks` 指 Claude Code 和 Codex 的 agent 桥接，而不是本地 Git 钩子；`platform` 指产品可移植性，而不是 CI 运行器选择；`build` 指编译、打包和已构建的包（package）产物，而不是文档生成器。
+
+### 可扩展性
+
+领域集合有意保持可扩展。当分类体系缺少一个会反复涉及且具有实际意义的仓库领域时，就新增领域；不要仅为一项 PR、临时项目、状态、个人或团队新增标签。当领域模型发生变化时，重命名、拆分或退役相应领域，同时更新本列表以及所有受影响的开放和已合并 PR。
+
+类型集合保持精简，因为各类型互斥。新增类型的前提是存在一种当前五类无法表达的独立变更意图；类型不能用来替代领域。
+
+## 曾考虑的替代方案
+
+- **一套不区分维度的标签。** 不予采纳，因为类型与领域回答的是不同问题；两者混在一起时，存在一个维度的标签并不表示另一个维度也经过了考虑。
+- **一套固定、封闭的领域集合。** 不予采纳，因为仓库领域会持续演变。封闭集合会以牺牲语义准确性为代价来维持拼写不变。
+- **一个宽泛的 `core` 领域，或从包结构派生的标签。** 不予采纳，因为 `session`、`llm` 和 `agent` 等领域在跨越包边界时仍各自具有意义，而偶然涉及的文件路径并不是评审人或自动化流程所需的范围信息。
+- **为浏览器和桌面端分别设置领域。** 不予采纳，因为浏览器交付和 Electron 打包共同呈现同一个图形客户端领域；拆开二者将按交付形态而非工作的语义进行分类。
+- **以宽泛的实现领域替代语义领域。** 不予采纳，因为持久化的定时作业不是后台任务，附件不只是其来源接口或文件系统实现，产物也不只是声明它的工具或预览接口。
+- **同一项契约同时使用总括领域与细分领域。** 不予采纳，因为重复标签只会虚增范围，不会增加信息。一项 PR 确实修改不同契约时，多个领域标签仍然合理。
+- **每项 PR 恰好一个领域。** 不予采纳，因为一项内聚的变更可以合理地跨越多个领域；省略次要领域会隐藏受影响的契约。
+
+## 后果
+
+- 评审人和自动化流程获得一个稳定的意图信号，以及完整的语义范围。
+- `gui` 查询会同时覆盖浏览器与桌面端交付，`ui` 查询则只涵盖共享的跨接口契约。
+- `schedule`、`attachment` 与 `artifact` 查询直接对应各自领域，无需通过实现依赖近似归类。
+- 选择标签仍然需要判断：路径和标题前缀可以提示领域，但不能替代阅读变更内容。
+- 变更分类体系会产生维护工作。新增、重命名、拆分或移除领域时，需要更新本决策记录，并回填开放和已合并的 PR，使历史查询保持原有含义。

## Problem
The [session-persistence seam](../architecture/2026-06-14-session-persistence.md) split a session's out-of-log metadata into two types owned by `dsh-session`: an immutable `SessionHeader` (`version`, `id`, `createdAt`, `cwd?`, `parentSession?`) written once at creation, and a mutable `SessionSummary` (`updatedAt`, `title?`, `firstPrompt?`) "updateable without touching the append-only log". Their union was `SessionMeta = SessionHeader & SessionSummary`, and the abstract `SessionPersistence` service carried a seventh method — `update(id, summary)` — for rewriting the summary. Each backend implemented the mutable store its own way: JSONL wrote a separate atomic `.summary.json` **sidecar** beside the log (temp-write + rename, best-effort), SQLite kept `updated_at`/`title`/`first_prompt` **columns** bumped inside the append transaction.
@@ -10,8 +12,8 @@ The summary was designed for a future session picker (recency ordering via `upda
- `SessionPersistence.update()` has **zero production callers** (every `.update(` hit is `createHash().update()` or a test).
- `firstPrompt` is **never read** anywhere in production.
-- `title` *is* read in the ACP bridge — but from a tool-call **presenter** (`present.title`), never from stored session metadata.
-- `updatedAt` has **no consumer**: the only production caller of `list()` reads `meta.cwd` (a `SessionHeader` field) to validate a workspace on `session/load`; resume reads `createdAt`/`cwd`/`parentSession` — all header fields.
+- Session titles come from durable `session/title` events, while tool-card titles come from tool presenters; neither reads mutable session metadata.
+- Persistence-list consumers use immutable header identity, creation, lineage, and cwd fields. Recency and previews derive from the log rather than an `updatedAt` summary.
- Decisively: the live `Session.header` was already typed `SessionHeader`, not `SessionMeta` — the summary never existed on the live session object; it lived only in the persistence layer, written and read by nothing but its own contract test.

+# Agent Note: 移除可变的会话摘要
+
+Status: implemented
+
+[English](2026-06-19-drop-mutable-session-summary.md) | 中文
+
+## 问题
+
+[会话持久化 seam](../architecture/2026-06-14-session-persistence.md)将会话的日志外元数据拆分为 `dsh-session` 拥有的两种类型：一个不可变的 `SessionHeader`（`version`、`id`、`createdAt`、`cwd?`、`parentSession?`），在创建时一次性写入；一个可变的 `SessionSummary`（`updatedAt`、`title?`、`firstPrompt?`），「可在不触碰仅追加日志的情况下更新」。二者的联合类型为 `SessionMeta = SessionHeader & SessionSummary`，抽象的 `SessionPersistence` 服务为此多出第七个方法 `update(id, summary)`，用于重写摘要。各后端各自实现可变存储：JSONL 在日志旁写一个独立的原子 `.summary.json` **伴随文件**（临时写入 + rename，尽力保证）；SQLite 在追加事务内更新 `updated_at`/`title`/`first_prompt` **列**。
+
+摘要是为未来的会话选择器设计的（通过 `updatedAt` 排序近期会话，用 `title`/`firstPrompt` 做预览）。该选择器从未实现。对整个仓库的审计表明，`SessionSummary` 的全部表面积都是**死状态**：
+
+- `SessionPersistence.update()` **零个生产调用方**（所有 `.update(` 匹配都是 `createHash().update()` 或测试代码）。
+- `firstPrompt` 在生产代码中**从未被读取**。
+- 会话标题来自持久的 `session/title` 事件，工具卡片标题来自工具 presenter；二者都不读取可变的会话元数据。
+- 持久化列表的消费方使用不可变 header 中的标识、创建、谱系和 cwd 字段。近期排序和预览派生自日志，而非某个 `updatedAt` 摘要。
+- 决定性的一点：活跃的 `Session.header` 类型本来就是 `SessionHeader` 而非 `SessionMeta`——摘要从未存在于活跃会话对象上；它只存在于持久化层，除了自身的契约测试外无人写入、无人读取。
+
+## 决策
+
+彻底删除可变的会话摘要。`SessionSummary` 与 `SessionMeta` 这个名称一并移除；后端存储和返回的元数据仅为 `SessionHeader`。`SessionPersistence.update()` 从抽象服务和所有后端中移除。JSONL 去掉整套伴随文件机制（`writeSidecar`/`readSidecar`/`touchSummary`/`removeSidecars`/`sidecarPath` 以及 load/list 的覆盖逻辑）；SQLite 去掉 `updated_at`/`title`/`first_prompt` 列以及每次追加时的 `updated_at` 更新，其 `SCHEMA_VERSION` 从 `1 → 2`。
+
+摘要原本要提供的一切，在消费方真正需要时都**可从仅追加日志中派生**（`firstPrompt` = 第一条 `user/message`；近期度 = 最后一个事件的 `time` 或文件 mtime），或者已经存在于不可变 header 中（`createdAt`、`cwd`）。唯一*不可*派生的是用户*手动编辑*的标题，但它从未实现，纯属 YAGNI；如果未来真有功能需要，它可以作为独立的日志事件或 header 字段回归。
+
+这被记录为一项决策，因为它具有**持久性**（它同时收窄两个后端的公共服务契约和磁盘格式）、**争议性**（summary 是有意为未来设计的结果，而非意外），也具有**意外性**（未来读者在原 Agent Note（agent 决策记录）描述 `SessionMeta` 的位置发现 `SessionHeader`，否则会追问 summary 为何消失）。它还为[共享持久化写入协调器](../architecture/2026-06-18-shared-persistence-write-coordinator.md)扫清障碍：不再有可变 summary 后，协调器的钩子接口不需要 `updateSummary` 钩子，JSONL sidecar 与 SQLite 列之间的持久性分歧也随之消失，使两个后端的写入路径趋于一致。
+
+## 无需迁移
+
+这是未发布的软件（见[根 AGENTS.md](../../../../AGENTS.md)「Pre-release stance: foundation over blast radius」一节），因此没有需要保留的磁盘数据库或日志。SQLite 不迁移 v1 数据库：`openDatabase` 守卫现在拒绝任何非当前版本的磁盘 `user_version`（`onDisk !== 0 && onDisk !== SCHEMA_VERSION`），无论更旧*还是*更新，因此陈旧的 v1 数据库会被干净地拒绝，而非在新列集下被半读取。新建数据库写入当前版本号；这是唯一需要正常工作的路径。
+
+## 后果
+
+未来的会话选择器现在必须从日志派生预览/排序信息（或重新引入一个类型化字段），而不能直接读取现成的摘要行。这是正确的代价：为一个尚不存在的功能维护缓存，是每个后端都要付出维护成本、每个契约测试都要付出断言成本的死重。这一原则——**通过的测试固定的是当前行为，不一定是正确行为；行为可能是过去妥协的产物**——现已作为独立约定记录在[根 AGENTS.md](../../../../AGENTS.md) 中，本次变更即为其实例。

## Problem
-The session event vocabulary includes first-class events that are not part of replayable conversation history and have little or no production consumption. `usage` is already present as a model stream chunk before the loop also appends a separate `usage` event. `error` duplicates the `turn/end { kind: 'error', message, code }` reason for loop failures; ACP settlement reads the turn-end reason, ACP rendering ignores the `error` event, and `deriveMessages()` skips it.

These events make the canonical transcript look more useful as telemetry than it currently is. They add event variants, invariants, tests, snapshots, and persistence cases, but they are not load-bearing as separate records. The facts they carry can still be useful: token usage should remain available for accounting, and an error's step number should not silently disappear. The simplification is to fold those facts into nearby events consumers already must understand, not to record less information.

+会话事件词汇中包含一些一等事件，它们不属于可回放的对话历史，在生产环境中几乎没有消费方。`usage` 已经作为模型流分片存在，之后循环又追加了一个独立的 `usage` 事件。`error` 与 `turn/end { kind: 'error', message, code }` 中的循环失败原因重复；ACP（Agent Client Protocol）结算读取轮次结束原因，而消息投影和 UI 投影都会跳过独立的 `error` 事件。
+
+这些事件让规范的 transcript（文本记录）看起来比实际更像遥测数据。它们增加了事件变体、不变式、测试、快照和持久化用例，但作为独立记录并不承载实际功能。它们携带的事实仍然有用：token 用量应当保留以供计费，错误的步骤编号也不应悄然消失。简化的方式是将这些事实折叠进消费方本已必须理解的邻近事件，而非减少记录的信息量。
+
+## 决策
+
+仅在信息已被保留、无需并行记录的情况下，移除独立的追踪事件：
+
+- 成功步骤的 usage 折叠进匹配的 `assistant/message`（`assistant/message { turn, step, content, usage? }`），使组装好的模型输出与其计费信息一同传递。
+- 失败或中止的步骤如果有 usage 但没有 assistant 内容，则将 usage 放在一个空内容的 `assistant/message` 上（下方实现说明给出了无信息丢失的证明）——不会有已持久化的 usage 分片无处安放。
+- 独立 `error` 事件中的步骤编号折叠进 `turn/end.reason`（当 `kind: 'error'` 时：`{ kind: 'error', step, message, code? }`）——`turn/end` 是 ACP 和恢复机制已经消费的持久轮次结果。
+- `agent/error` 与日志保留用于实时诊断；`turn/end` 之后不再有第二条会话日志错误记录。
+
+用户对话日志包含渲染、恢复、审计和计费所需的全部信息，消费方无需协调重复的追踪行。
+
+## 曾考虑的替代方案
+
+**保留独立行作为遥测**——这些事件让规范 transcript 看起来比实际更像遥测数据，代价是增加了事件变体、不变式、测试、快照和持久化用例，却没有任何消费方使用。如果分析需求真正出现，正确的形态是投影辅助工具或带有独立保留策略的专用遥测存储，而非对话日志中的重复追踪行。
+
+## 验证
+
+`SessionEventMap` 不再包含独立的 `usage` 或 `error`；agent loop（智能体循环）不再追加独立的 usage 事件，持久性失败通过 `turn/end { kind: 'error', step, message, code? }` 记录；ACP 快照和持久化测试断言不存在仅追踪行；已录制的 fixture（测试前置数据）使用新事件形状，会话格式版本固定为 `0`（后端按预发布格式策略拒绝任何非 `0` 的存储日志）；文档说明了 token 用量和操作错误的观测位置。
+
+## 后果
+
+消费方不能再从规范日志中筛选独立的 `usage` 或步骤级 `error` 行，必须从承载它们的 assistant/failure 事件中读取这些事实。只有在实现 PR（Pull Request）证明相同事实仍然存在的前提下，这才是合理的简化；否则独立事件应予保留。
+
+## 实现说明
+
+按提案落地，但有一处范围细化（遵循 AGENTS.md 所述“Agent Note（agent 决策记录）是提案，而非绝对真理”）：
+
+- **空内容 `assistant/message` 承载 usage，无数据丢失。** 提案要求的证明（不会有已持久化的 usage 分片无处安放）落在 max-tokens 路径上：一个被截断的步骤有 usage 但内容为空（例如只有一个被丢弃的工具调用），以前会发出独立的 `usage`。现在它记录一个空内容的 `assistant/message { content: [], usage }`。为防止这向提供方 transcript 注入一个无内容的虚假 assistant 轮次，`deriveMessages()` 跳过空内容的 `assistant/message` 事件。回归测试断言 usage 仍被表示，且派生历史未被破坏。
+
+**格式版本。** 此变更影响已持久化的事件，但预发布会话格式仍固定为 `0`，拒绝任何其他版本且不做迁移。`dsh-session` 拥有写入方和加载校验使用的常量。单调递增的格式版本从首次正式发布开始。
+
+Usage 现在通过 `assistant/message.usage` 观测；操作错误的步骤编号通过 `turn/end.reason`（当 `kind: 'error'` 时）观测。`agent/error` 与日志用于实时诊断，保持不变。

## Problem
`LlmService.registerAdapter()` emits `llm/adapter-change` on registration and disposal ([packages/llm/llm/src/index.ts](../../../../packages/llm/llm/src/index.ts)). Grepping `llm/adapter-change` across `packages/*/src` and `examples/*/src` finds only the declaration, emit sites, docs, and tests; no production listener subscribes to it.

+# Agent Note: 移除未被消费的 `llm/adapter-change` 事件
+
+Status: implemented
+
+[English](2026-06-20-drop-unconsumed-llm-adapter-change-event.md) | 中文
+
+## 问题
+
+`LlmService.registerAdapter()` 在注册和 dispose（资源释放）时发出 `llm/adapter-change` 事件（[packages/llm/llm/src/index.ts](../../../../packages/llm/llm/src/index.ts)）。在 `packages/*/src` 和 `examples/*/src` 中搜索 `llm/adapter-change`，只能找到声明、emit 站点、文档和测试；没有任何生产环境的监听器订阅它。
+
+这与 `tools/change` 和 `system-prompt/change` 不同。如今这两个事件同样没有消费方，但它们有望成为未来实时工具/提示词 UI 的注册表变更信号。LLM（大语言模型）适配器注册更像是启动时的实现细节：适配器不是用户可见的选项面板，真正的模型调用拦截 seam 是 `llm/stream`。保留一个没有监听器的适配器变更事件，只是在更小范围内重复[删除无用 summary](2026-06-19-drop-mutable-session-summary.md) 的模式。
+
+这个事件并非零成本。`registerAdapter()` 在发出 `llm/adapter-change` 之前先 yield 回滚 disposer，这样抛出异常的监听器会回退变更而非泄漏适配器条目；包内还有针对该监听器抛出路径的测试。这种防御性排序保护的是一个只有测试才能触发的失败模式。
+
+## 决策
+
+只移除 `llm/adapter-change`：包括 `dsh-llm` 的 `interface Events` 中的声明、`ctx.emit('llm/adapter-change')` 调用，以及 `LlmService.registerAdapter` JSDoc 中“在注册和释放时发出 `llm/adapter-change`”的句子。`registerAdapter()` 的效应生成器为 HMR（热模块替换）/释放保留变更与回滚 disposer，但移除仅因该事件而存在的监听器抛错回滚顺序。适配器 disposer 测试断言返回的 disposer 会移除适配器，不再订阅事件；监听器抛错回滚测试则随其测试对象一起消失。[docs/architecture.md](../../../../docs/architecture.md) 和 [packages/llm/llm/README.md](../../../../packages/llm/llm/README.md) 中的事件分类也在同一变更中更新。
+
+## 曾考虑的替代方案
+
+### 为什么不移除所有注册表变更事件？
+
+由注册表通告变更的微内核是一种一致的约定。当 UI 能够实时刷新可用工具或提示词章节时，`tools/change` 和 `system-prompt/change` 可能会有用。本 Agent Note（agent 决策记录）在存在合理用户侧消费方的位置保留该约定，只删除当前及可能的未来消费方都不明确的适配器变更事件。
+
+如果将来需要 LLM 适配器浏览器或动态模型选择器用到此信号，届时再连同消费方一起重新引入，并提供比「something changed」更清晰的 payload。
+
+## 验证
+
+`llm/adapter-change` 及其 emit 已消失，重新生成的 Cordis 目录保持新鲜；HMR 安全性仍成立（释放贡献该适配器的 fiber 会移除它）；`tools/change` 和 `system-prompt/change` 仍有文档与测试；ACP（Agent Client Protocol）快照和无密钥 Headless Loader 冒烟则固定了未变的生产路径。
+
+## 后果
+
+- **移除一个已文档化的 emit 事件属于公开接口变更。** 它出现在分类体系表中，读起来像有意设计的 API。但「已声明且已发出」不等于「已被消费」——这与移除可变 summary 时的判断依据相同。分类体系表在同一个变更中更新，因此文档不会漂移。
+- **注册表变更约定变得不均匀。** 这是可接受的，因为 LLM 适配器注册与工具或提示词段落不是同一层面的面向用户概念。不均匀但诚实，胜过统一但无用。
+
+这是一个小裁剪，但它退役了一条守护着并不存在的消费方的正确性不变式。

+# Agent Note: 移除未被消费的 LLM 组装便捷接口
+
+Status: implemented
+
+[English](2026-06-20-drop-unconsumed-llm-assembled-surfaces.md) | 中文
+
+## 问题
+
+`LlmService`（[packages/llm/llm/src/index.ts](../../../../packages/llm/llm/src/index.ts)）在模型之上暴露了三个调用接口：
+
+- `stream()`：原始 `StreamChunk`，通过 `llm/stream` waterfall（瀑布式事件）分发。
+- `streamBlocks()`：一个「便捷视图」，将分片送入 `BlockAssembler` 并按流顺序产出已组装的 `ContentBlock`（[index.ts:137-144](../../../../packages/llm/llm/src/index.ts)）。
+- `generate()`：一个完整组装的 `GenerateResult`，通过第二条 `llm/generate` waterfall 分发（[index.ts:151-157](../../../../packages/llm/llm/src/index.ts)）。
+
+LLM（大语言模型）服务唯一的生产消费方是 agent loop（智能体循环），它只使用 `stream()`：将原始分片送入自己的 `BlockAssembler`，以便在并行组装的同时记录分片，保证回放保真度（[packages/core/agent-loop/src/loop.ts](../../../../packages/core/agent-loop/src/loop.ts)，`ctx.llm.stream(req)` 步骤）。在 `packages/*/src` 和 `examples/*/src` 中 grep `streamBlocks` 与 `ctx.llm.generate`，找不到任何生产调用方。仅有的引用来自服务方法定义、文档和测试；适配器测试用 `generate()` 作为便捷驱动，但它们完全可以通过同一个 assembler 辅助函数手动消费 `stream()`，无需为此保留一个公开的生产 API。
+
+这属于[删除可变会话 summary](2026-06-19-drop-mutable-session-summary.md) 的同类模式：带有受测契约的组装视图 API，由测试而非生产代码消费。它们是为不关心 token 级增量的消费方推测性构建的，但唯一的真实消费方恰恰关心增量，以便持久化高保真重放数据。
+
+`streamBlocks()` 拖带了 `BlockAssembler` 的一块专用逻辑：`flushReady()` 与 `flushRemaining()`（[packages/llm/llm/src/assembler.ts:138-168](../../../../packages/llm/llm/src/assembler.ts)）以及 `flushed` 游标字段，仅为支持按序增量产出而存在。`generate()` 拖带了 `GenerateResult`、`BlockAssembler.result()` 以及 `llm/generate` waterfall——在同一底层流之上的第二个拦截面。agent loop 对 assembler 的使用仅限于 `push()` / `message()` / `usage` / `finish`，不涉及流式 flush 或一次性服务组装。
+
+## 决策
+
+`stream()` 是唯一的公开 LLM 调用接口。移除 `streamBlocks`、`generate`、其事件/结果类型，以及仅被该路径使用的 assembler 辅助方法。适配器测试通过本地辅助函数对公开流进行组装；`BlockAssembler` 仅保留有生产消费方的操作。
+
+## 曾考虑的替代方案
+
+**保留 `generate()` 作为仅供测试的便捷方法**：否决。适配器测试通过共享 assembler 手动消费 `stream()`，走的是与生产完全相同的流式路径；一个唯一调用方只有测试的公开方法，正是 [drop-mutable-summary 先例](2026-06-19-drop-mutable-session-summary.md)所淘汰的死接口形态。未来如果有消费方需要不带增量的组装块，届时再为该消费方引入一个聚焦的辅助方法。
+
+## 验证
+
+`streamBlocks`、`generate`、`llm/generate` 及仅供它们使用的 assembler 辅助函数均已移除，且未产生新的无用导出；两个真实适配器都通过 `stream()` 和共享 assembler 接受测试；循环行为保持一致（ACP（Agent Client Protocol）快照预期输出未变）；README、架构文档和模块文档也不再提及已删除表面。
+
+## 后果
+
+- **从一个核心词汇包中移除了公开方法。** 未来如果有插件需要不带增量的组装块，它需要直接调用 `stream()` 并使用 `BlockAssembler`，或在有真实消费方时重新引入一个聚焦的辅助方法。鉴于预发布阶段「基础优先于预设未来」的立场（[AGENTS.md](../../../../AGENTS.md)），现在正是裁剪仅供测试的公开接口的合适时机。
+- **适配器测试变得更显式。** 它们失去了便捷的 `generate()` 包装层，但这是有益的压力：测试走的是与生产相同的流式路径。
+- **waterfall 使用者失去 `llm/generate`。** 不存在生产监听者。未来的缓存/重试/日志插件应包装 `llm/stream`，它仍然是唯一的提供方调用路径。
+
+改动规模不大，但它从 LLM 包中干净地移除了预设的接口面积，为生产和测试留下唯一一份模型调用契约。

+# Agent Note: 从持久化 seam 中移除无用方法
+
+Status: implemented
+
+[English](2026-06-20-prune-dead-seam-methods.md) | 中文
+
+> **实现说明：** 仅移除了 `SessionPersistence.has()` 和 `.delete()`。`BashExecutor.get()` 和 `.list()` 仍然保留，因为删除它们的单行查找表面会要求消费方增加显著更多的完成跟踪机制。其 id 品牌化由[品牌化 id Agent Note（agent 决策记录）](../architecture/2026-06-20-branded-ids.md)负责。
+
+## 问题
+
+能力 seam（[接口 / 实现 / 消费方](../architecture/2026-06-13-capability-seams.md)）承载了没有消费方调用的抽象方法。seam 的存在是为了让实现和消费方独立演进——但没有消费方以之编程的方法不是 seam，而是每个实现仍必须实现和测试的推测性表面。
+
+### `SessionPersistence.has()` 与 `.delete()`
+
+该抽象服务在 create/append 之外声明了更多操作：`load`、`list`、`has`、`delete`。生产消费方用 `load()` 和 `list()` 完成恢复与会话发现，而没有任何生产调用方使用持久化的 `has()` 或 `delete()`。协议和 UI 代码中名称相似的内存集合调用与此无关。持久化 `has`/`delete` 的唯一调用者是契约测试套件和各后端的 spec。
+
+`has()` 不仅未被使用：在 `loadStored(id)` 已负责持久化存在性检查的情况下，它仍增加了协调器的已跟踪/未跟踪探测和一个契约分支。`delete()` 则拖入每个后端都必须实现的 `deleteStored` 后端钩子。这属于[删除可变会话 summary](2026-06-19-drop-mutable-session-summary.md) 的同类模式：契约测试覆盖了两者，但已发布代码从不会询问“这个会话是否已持久化？”或删除某个会话。
+
+## 决策
+
+没有消费方使用的方法被移除——从抽象 seam、实现，以及仅为覆盖它们而存在的契约/spec 测试套件中移除：
+
+- `SessionPersistence.has()` / `.delete()` 已移除：抽象声明、协调器的 `has`/`delete`/`deleteCore`，以及 `PersistenceBackend.deleteStored` 钩子均消失（jsonl 和 sqlite 都只是为了满足该钩子才实现 `deleteStored`，这些实现也一并移除）。后端属于[双后端](../architecture/2026-06-14-session-persistence.md)设计，其他方面不在范围内；删除它们为没有消费方的钩子所做的实现，是删除钩子的一部分，而非重新设计后端。
+- 所有文档和源码注释引用都已更新为保留下来的四方法、仅含 `list()` 的契约——不仅包括字面上的 `has(`/`delete(`/`deleteStored` 拼写，还包括 `{@link has}`/`{@link delete}` JSDoc 链接和“六个公共方法”的计数——涉及 seam 和后端 README、[docs/architecture.md](../../../../docs/architecture.md)、[会话持久化](../architecture/2026-06-14-session-persistence.md)与[写入协调器](../architecture/2026-06-18-shared-persistence-write-coordinator.md) Agent Note，以及协调器/后端 JSDoc。
+
+## 曾考虑的替代方案
+
+### 为什么不以「seam 应当完整」为由保留？
+
+「持久化 seam 理应提供 delete」这种直觉是真实的——但它恰恰是预发布阶段所警惕的投机性完整（[AGENTS.md](../../../../AGENTS.md)：为正确的基础优化，而非为你并不拥有的假想调用者优化）。`delete()` 是一个方法，等消费方真正需要时再加回来即可：一个删除旧会话的会话管理 UI 会需要它——到那时再加，基于该 UI 的真实需求来设计（软删除？级联？确认？），而非现在猜测。
+
+在有活跃消费方的情况下重新添加一个 seam 方法，成本低且设计更优，因为消费方锚定了契约。在无人使用的情况下保留它，意味着每个实现（以及未来的每个后端）都必须实现和测试一个无实际作用的方法。
+
+## 验证
+
+`has`/`delete`/`deleteStored` 已从持久化 seam、实现和契约测试套件中移除，没有新增无用导出；剩余操作（`create`/`append`/`load`/`list`）未受影响，基于持久化的会话查询和崩溃恢复行为完全一致；seam README 和 `docs/architecture.md` 仅列出存留的方法。
+
+## 后果
+
+- **`delete()` 是产品最终会需要的操作。** 确实如此，但「最终」正是关键。现在删除、将来基于真实消费方重新添加，严格优于发布一份猜测的契约。两个后端各自减少了一个 `deleteStored` 实现，这是在本次范围之外的包中的有限改动。
+- **低耦合。** 移除局限于持久化 seam + 实现 + 测试；没有跨包消费方引用被移除的方法，因此除文档外没有涟漪效应。

+# Agent Note: 保留单一公开停止原语
+
+Status: implemented
+
+[English](2026-06-20-public-agent-stop-surface.md) | 中文
+
+> **实现说明：** 仅移除了 `abort()`。`whenIdle()` 予以保留，因为它是公开的完全停稳信号，能安全处理等待者结算与替换轮次竞态；消费方不应从状态转换中自行重建该行为。
+
+## 问题
+
+公共 `Agent` handle 暴露了两种相互重叠的在途工作停止方式：仅针对步骤的 `abort()` 和感知队列的 `cancel()`。前者保留已排队输入，后者则清除已排队和 steering（中途引导）工作，并中止活动轮次。在生产中，ACP（Agent Client Protocol）对 `session/cancel` 使用 `cancel()`，生命周期拥有者则通过 `AgentHandle.dispose()` 拆除 agent（智能体）。没有生产调用方需要一个裸的、仅针对步骤的 abort。
+
+行为差异确实存在，但已发布代码不需要较窄的操作。AgentLoop 改为为整个轮次拥有一个私有取消 holder。`cancel(cause?)` 携带类型化的 `user` 或 `parent` 原因，默认为 `user`，并丢弃待处理输入；释放仍是单独的生命周期中断。完整的归属与传播契约位于[显式轮次取消 Agent Note（agent 决策记录）](../architecture/2026-07-16-explicit-turn-cancellation.md)。
+
+多余的公开接口使得循环不得不承载一个本质上属于内部拆卸的公开动词：`abort()` 必须被文档描述为有别于队列感知的取消，尽管 UI 取消几乎总是需要更广泛的操作。
+
+## 决策
+
+`cancel()` 是 `Agent` 上唯一的公共*停止*原语。生命周期拥有者使用 `AgentHandle.dispose()` 停止并注销 agent；非拥有者使用 `cancel()` 放弃当前和已排队工作。实现保留一个私有轮次取消 holder，但它不属于面向插件的 `Agent` 契约。
+
+`whenIdle()` **保留**为公开的完全停稳观测原语（agent 从 `running` 状态稳定后 resolve，已处于 idle 时立即 resolve，dispose 后等待循环退出）。它不是停止动词；它是非所有者在不 dispose agent 的前提下观测停止*完成*的方式。它的活跃消费方是 ACP 和通过此公开 seam 等待结算的 agent 测试（`packages/acp/acp/tests`、`packages/core/agent-loop/tests`）；生产环境的 ACP 桥接层拥有其 agent 并通过 `AgentHandle.dispose()` 销毁它们，因此 `packages/acp/acp/src` 本身没有 `whenIdle()` 调用。
+
+公共 `abort()` 已不存在，disposer 仍为异步并等待循环停止。测试通过公共类型化原因和显式 signal seam 验证取消，而不会伸入 holder 内部。
+
+## 曾考虑的替代方案
+
+**同时移除 `whenIdle()`**：最初提案的形态，在对照代码验证前提后被推翻（上方的实现说明记录了完整过程）：它是承重的完全停稳原语，迫使消费方手动观测 `running`→`idle` 转换正是防御性模式所警告的脆弱路径。
+
+## 验证
+
+`Agent` 不再暴露公开的 `abort()`，而 `cancel()`、`whenIdle()` 和 `steer()` 保留；ACP 取消调用 `cancel()`；拆卸通过 handle disposal 等待完全停稳，`whenIdle()` 在完全停稳时为非所有者观测者 resolve；测试套件覆盖取消和 disposal 作为两条受支持的停止路径。
+
+## 后果
+
+未来的插件无法通过公开接口仅中止当前模型/工具步骤而保留队列中的提示词。如果该用例变为现实需求，它应当带着一个具名消费方和更窄的契约回归。目前它是将私有循环机制保持公开的潜在泛化。
+
+## 相关
+
+本 Agent Note 只移除冗余的停止动词。轮次中途 steering 仍是一条有意保留的消息路径；完全停稳观察仍通过 `whenIdle()` 完成。最终公共表面包括 `send()`、`steer()`、`inject()`、`cancel()`、`whenIdle()`、status、options、会话和 identity。

This duplication is not free. Every lifecycle change had to update the session event, the mirror event, docs, invariants, tests, and snapshot expectations. The duplicate boundary events also made failure ordering subtle: a turn can be durably closed before a live `agent/turn-end` listener runs, so a post-boundary listener failure has no valid in-log position left and must be reported out of band.

+ 和[移除 `agent/steering` 镜像 emit](2026-07-04-remove-agent-steering-mirror.md)。 -->
+
+## 问题
+
+循环在 `SessionEvent` 中记录规范 transcript（文本记录），同时还发出一组并行的实时 `agent/*` 边界镜像事件：`agent/turn-start`、`agent/turn-end`、`agent/step-start` 和 `agent/step-end`。这些镜像迫使消费方在同一持久事实的两个真源之间做选择。ACP（Agent Client Protocol）已经为提示词结算和已提交输出选择会话日志，因为它是唯一持久、可重放的记录；消费实时镜像需要把它的时序与日志中已经存储的边界进行调和。stdio UI 是唯一仍从镜像事件渲染轮次边界的生产消费方；它已经从 `session/event` 渲染工具调用和结果。
+
+这种重复并非零成本。每次生命周期变更都需要同时更新会话事件、镜像事件、文档、不变式、测试和快照预期。重复的边界事件还使失败排序变得微妙：一个轮次可能在实时 `agent/turn-end` 监听器运行之前就已被持久化关闭，因此边界之后的监听器失败在日志中已没有合法位置可以插入，只能带外上报。
+
+## 决策
+
+将 `session/event` 作为唯一的实时边界/transcript（文本记录）流。需要渲染轮次、工具调用、工具结果、助手消息和持久化边界的消费方统一订阅 `session/event`，从持久化层使用的同一套事件词汇中派生 UI。
+
+四个持久边界镜像——`agent/turn-start`、`agent/turn-end`、`agent/step-start`、`agent/step-end`——已从 agent（智能体）事件分类中移除。希望在边界处取得 agent handle 的 UI 会保留来自 `agent/created`/`agent/disposed` 的实时目标对象，并直接比较其会话；`dsh-ui-stdio` 据此为应用拥有的 agent 标记 `[main turn N]` 头部，其他会话则渲染其持久 id。规范记录仍是事件溯源会话日志。
+
+步骤镜像（完全没有消费方）最先在[事件域语义 Agent Note（agent 决策记录）](../architecture/2026-06-30-event-domain-semantics.md) 中移除；该 Agent Note 当时以 stdio UI 需要在轮次边界取得 `Agent` handle 为由，保留了轮次镜像。本 Agent Note 完成余下工作：`dsh-ui-stdio` 是可随时丢弃的测试 REPL，其渲染可以自由变化，因此“ui-stdio 需要它”并不是保留镜像的理由——它读取 `session/event`，只保留自己的实时目标对象。
+
+## 范围：移除什么、不移除什么
+
+已移除（持久边界镜像——每项都以会话日志为权威）：`agent/turn-start`、`agent/turn-end`、`agent/step-start`、`agent/step-end`。
+
+保留——不是持久边界镜像，因此不在本决策范围内：
+
+- `agent/steering`——不是边界，因此不在本决策范围内（原始提案将其一并移除；在此会造成范围蔓延）。它镜像持久的 `steering/message` 控制记录，而非边界，后来由自己的后续决策移除：[移除 `agent/steering` 镜像 emit](2026-07-04-remove-agent-steering-mirror.md)。
+- `agent/stream-chunk`——实时 token 流。不在本决策范围内（它镜像持久的 `assistant/chunk`，而非边界），后来由自己的后续决策移除：[停止将 token 流镜像为 agent 事件](2026-07-02-remove-stream-chunk-mirror.md)。
+- `agent/created`、`agent/disposed`、`agent/status`、`agent/error`、`agent/queued`——不属于 transcript 数据的生命周期/控制事件。尤其是 `agent/queued`，它是在任何持久事件存在之前触发的 inbox 确认（取消的排队工作可能永远不会进入日志），所以有意只保留为实时事件。
+
+## 曾考虑的替代方案
+
+- **将 `agent/steering` 一并移除**——原始提案的形状；作为范围蔓延被排除：它镜像持久的 `steering/message` 控制记录，而非边界，后来由[自己的决策](2026-07-04-remove-agent-steering-mirror.md)移除（`agent/stream-chunk` 也由[流分片镜像 Agent Note](2026-07-02-remove-stream-chunk-mirror.md)移除）。
+- **为 stdio UI 保留轮次镜像**——[事件域语义 Agent Note](../architecture/2026-06-30-event-domain-semantics.md) 的原始立场；在此否决，因为 `dsh-ui-stdio` 是可随时丢弃的测试 REPL，而非承载关键约束的消费方，并且它改为根据 `session/event` 加自己的实时目标对象渲染边界。
+
+## 后果
+
+插件不能再从便捷的 `Agent` 优先事件观察轮次/步骤边界。它需要订阅 `session/event`；如果需要实时对象，则通过 `ctx.agents` 解析共享 id，或保留自己已经拥有的对象。这是可以接受的取舍：边界消费方不应依赖可能与持久日志发生漂移的第二条事件 feed。

## Problem
A live agent/session pair needs one identity for registry routing, event sourcing, and persistence. Giving the factory independent `agentId` and `sessionId` inputs would permit pairings no production path can use, while forcing every consumer to choose or translate between two names for the same lifecycle.

+# Agent Note: 统一 agent id 与会话 id
+
+Status: implemented
+
+[English](2026-06-20-unify-agent-and-session-id.md) | 中文
+
+## 问题
+
+一个实时 agent（智能体）/会话对需要使用同一 identity 完成注册表路由、事件溯源和持久化。让 factory 接受相互独立的 `agentId` 和 `sessionId` 输入，会允许任何生产路径都无法使用的配对，同时迫使每个消费方为同一生命周期在两个名称之间选择或转换。
+
+ACP（Agent Client Protocol）对两种 identity 使用相同值。Stdio 和钩子也在会话事件流上工作，并且直接需要对应的实时 agent；没有生产路径会把一个实时 agent 对象重新附着到多个会话，或通过多个 agent id 驱动一个会话。
+
+[agent 范围运行时](../architecture/2026-07-12-agent-scope-runtime-design.md)使用同一个 `AgentCreationTransaction` 执行创建和恢复，agent/会话条目共享相同的最终条目冲突规则。第二个 identity 并不代表单独的存活性、回滚或完全停稳；它只会围绕同一事务增加 API 与转换状态。
+
+会话 identity 同样只有一个归属，即 `Session.header.id`；`Session.id` 是派生访问器，而非需要重复验证的独立状态。
+
+## 决策
+
+agent 的注册表 id 等于其会话 id。`CreateAgentOptions` 接受一个 `sessionId`，同时用于两个最终注册表条目；恢复时以 `resumeSessionId` 注册 agent；进程内 subagent 创建使用子会话 id；`Session.id` 则派生自 `header.id`。远程 ACP 运行没有本地 agent/会话对：它保留一个由父项铸造的生命周期 id，而子服务器线协议内的会话 id 仅用于 ACP 调用。现有创建事务、最终条目冲突检查和精确条目分离语义保持不变；唯一职责是在本地 id 之间转换的 map 与字段已经消失。
+
+配置驱动路径保留 `agents[].id` 作为稳定配置标签，而非实时路由 identity。普通的全新启动会铸造组合 id `${label}-session-${randomUUID()}`，使持久重启不会冲突。耦合应用可以预先铸造并传入精确的 `sessionId`：首次使用时创建它，而当持久化服务已经存在时，AgentLoop 重新挂载会在同一 identity 下恢复已物化历史。`resumeSessionId` 则要求已有的持久化 identity。两个精确 id 输入互斥。Stdio 使用“恢复或创建”形式，使配置创建的 agent 和 UI 在循环重载之间共享一个不透明 identity，而不是根据前缀猜测。日志可以使用稳定标签，而所有实时与持久查找都使用同一个 `SessionId`。
+
+`agent/created` 和 `agent/disposed` 保留。它们是成对的发布生命周期事件，而非 identity 别名；以后若发现没有消费方并要移除，必须先重新搜索，再提出独立提案。
+
+## 曾考虑的替代方案
+
+**保持路由与日志 identity 分离。** 稳定的配置标签加全新的持久对话确实有用，但不需要两个实时 identity：标签可以继续作为配置/显示元数据，而每次运行的组合 `SessionId` 负责路由和持久化。保留两个 id 会让转换 map 持续存在，允许不可能的配对，却不会增加生命周期功能。
+
+## 验证
+
+- Agent 创建/恢复和 subagent 创建只携带一个 identity，`Session` 也只在一个位置存储它。
+- 创建事务继续覆盖最终条目冲突、精确条目分离、回滚和完全停稳，无需 identity 特有的生命周期状态。
+- ACP、stdio、钩子、bash 归属、持久化和 lineage 直接使用共享 `SessionId`。ACP subagent 后端在父命名空间中铸造其生命周期 id，因为子服务器返回的会话 id 仅在服务器本地有效；ACP bridge 根据正向会话 map 验证精确的 `Agent` 归属；JSON-RPC 只转发生命周期事件中由服务快照保存的 `local` 标记为 true 的事件，从带范围的事件 carrier 取得委托父项，并且不保留子 identity 或 lineage cache。
+- 配置驱动的恢复还是创建策略是显式的，并在持久化重启场景下得到覆盖。
+- 生产监听器搜索确认保留 `agent/created`/`agent/disposed` 及其发布语义。
+- 类型检查、覆盖率、快照、doc-sync、module-graph 校验、构建与 hygiene 全部通过。
+
+## 后果
+
+这排除了潜在的多会话 actor 和会话交接设计，并使由客户端选择、已持久化的会话 identity 成为注册表 identity。如果独立路由 identity 成为真实需求，就需要显式的生命周期设计，而不是由调用方提供一对不受约束的值。

+这导致每个未来的后端都要重新实现面向模型的读取语义和观测策略。`readPage` 返回带行号的行和视图元数据；基础服务按 owner 存储文件状态，并区分 `full` 与 `partial` 读取。这些是有用的策略，但它们不是文件系统提供方的原语。字面文本变更则不同：版本守卫、字面匹配、歧义检测与原子重写必须留在提供方的变更边界内，但当前的 `applyEdit` 命名及其周围的 seam 将这一提供方操作绑定到了旧的读后编辑策略形状上。
+
+这还造成了一个真实的用户体验死胡同：窗口化读取记录 `view: partial`，而 partial 视图无法授权 `edit`。一个模型读取了大文件的第 100-150 行，如果想编辑第 120 行，就必须先获取一次 `full` 读取，而对于超过读取上限的文件这可能做不到。字面编辑实际上只需要新鲜度：被匹配的字节仍然来自模型所读取的那个版本即可。
+
+旧 Agent Note（agent 决策记录）已经推迟了独立的 `@deepseek-ai/dsh-fs-policy` 包。本 Agent Note 构建该层，使 `ctx.fs` 保持接近 fsspec 风格的存储原语（`info`/`cat`/`open`），但不把它变成完整的 fsspec。
+
+## 决策
+
+将栈拆为四层：
+
+```text
+tool dsh-tool-fs model-facing schemas + read windowing + text rendering; the EXECUTOR (reads/writes/edits via ctx.fs, dispatches the fs/* events)
+policy dsh-fs-policy observed-state + read-before-edit + write/edit freshness, contributed through the fs/* event gate (no service)
+provider seam dsh-fs ctx.fs: text IO + atomic mutation primitives (optional version guard)
+provider dsh-fs-local local implementation of ctx.fs
+```
+
+`dsh-tool-fs` 保持相同的面向模型的 `read`/`write`/`edit` schema。它是执行器：注入 `fs`（不是策略服务）并直接访问 `ctx.fs`，拥有读取窗口化逻辑，并分发 `fs/*` 事件以便 `dsh-fs-policy` 进行门控和记录。
+
+本 Agent Note 决定了四层拆分、提供方契约和新鲜度策略。随后，[事件门禁 Agent Note](../architecture/2026-06-26-file-context-as-event-gate.md) 细化了工具↔策略耦合：`dsh-fs-policy` 是通过 `fs/*` 事件参与的门禁插件，而非 `ctx.fileContext` 方法服务，因此工具不会在方法层与其耦合；读取窗口和 fs I/O 位于 `dsh-tool-fs`。本文描述已经落地的事件门禁形状；提供方的版本守卫可选（省略即无条件裸提供方）。
+
+## 提供方契约
+
+`@deepseek-ai/dsh-fs` 收缩为提供方文本 IO 加受保护的文本变更：
+
+```ts ignore-check
+abstract resolve(path: string, opts?: { cwd?: string; signal?: AbortSignal }): Promise<FsTarget>
+abstract stat(target: FsTarget, signal?: AbortSignal): Promise<FsInfo | undefined>
+abstract readText(target: FsTarget, signal?: AbortSignal): Promise<string>
+abstract streamText(target: FsTarget, signal?: AbortSignal): Promise<AsyncIterable<string>>
+abstract writeText(target: FsTarget, content: string, expected: FsWriteIntent, signal?: AbortSignal): Promise<FsWriteOutcome>
+abstract editText(target: FsTarget, edit: FsEditRequest, expected: { version: FsVersion }, signal?: AbortSignal): Promise<FsEditOutcome>
+
+interface FsInfo {
+ version: FsVersion
+ type: 'file' | 'directory' | 'other'
+ size?: number
+}
+
+type FsWriteIntent =
+ | { kind: 'createIfAbsent' }
+ | { kind: 'replaceIfVersion'; version: FsVersion }
+```
+
+`stat` 返回元数据而非内容。`version` 是新鲜度令牌；`type` 让执行器在读取前拒绝目录/特殊文件；`size` 让 `read` 工具无需通过失败探测即可选择 `readText` 还是 `streamText`。`undefined` 表示目标不存在。
+
+`readText` 读取整个常规文本文件。`streamText` 以相同的文本语义流式读取大文件。两个提供方原语负责常规文件检查、UTF-8 解码、二进制/NUL 拒绝以及 `FS_NOT_TEXT`；策略层从不处理原始字节，也不重新实现跨分片解码。`readText` 是小文件/直接全文件原语，而面向模型的大文件读取使用 `streamText`。
+
+`writeText` 是原子的临时文件 + rename，带有显式的写入期望。`createIfAbsent` 创建不存在的目标，对已存在的目标以 `FS_NOT_OBSERVED` 拒绝；这是 owner 没有先前读取时使用的路径。`replaceIfVersion` 仅在目标以观测到的版本存在时替换；目标不存在或版本不匹配时抛出 `FS_STALE_VERSION`。
+
+`editText` 是提供方级别的受保护文本变更。启用守卫时，它首先验证目标仍以 `expected.version` 存在，然后读取当前文本、应用字面替换并原子写入。陈旧检查必须在字面匹配之前发生，这样基于旧读取的编辑会报告 `FS_STALE_VERSION`，而不是对更新内容进行匹配后报告 `FS_EDIT_NOT_FOUND` 或 `FS_AMBIGUOUS_EDIT`。将此原语保留在提供方 seam 上，保持了后端本地锁定的能力，也让未来的远程后端能够实现原生的 compare-and-edit，而无需策略层拉取整个文件。
+
+这是一个*文本存储* seam，刻意比字节级 fsspec（`cat`/`open` 返回原始字节）高半个层次。UTF-8 解码、二进制/NUL 拒绝、受保护的全文件写入和受保护的字面文本编辑都在提供方内完成，因此策略层从不接触原始字节、不重新实现跨分片解码、也不将陈旧检查与变更临界区分离。面向模型的概念仍然不下沉到提供方：行窗口、带行号的行、渲染的页脚、观测状态存储都不会泄漏下去。
+
+从 `dsh-fs` 删除：`readPage`、`FsExpectation`、`FsView`、`FsStateSource`、`FsReadRequest`、`FsTextLine`、行/窗口常量、`formatReadBody` 和 observed-state `WeakMap`。`applyEdit` 由更窄的提供方原语 `editText` 取代，其契约是带版本守卫的字面文本变更，而非策略层读取授权。`FS_PARTIAL_OBSERVATION` code 也从 `FsErrorCode` 分类中移除：新鲜度授权没有部分/完整之分，因此没有任何路径会抛出它。`FsTargetKey` 和 `FsVersion` 按现有[品牌化 id Agent Note](../architecture/2026-06-20-branded-ids.md) 成为品牌化不透明 id。
+
+## 策略契约
+
+`@deepseek-ai/dsh-fs-policy` 是插件，而非服务：它不注册任何 `ctx.*` 键，也不注入任何内容。它拥有不应位于 `FileSystem` 提供方基类上的写入/编辑新鲜度策略和 observed state（否则沙箱/远程后端会继承不该由其承载的面向模型观察策略）。它通过执行器分派的 `fs/*` 事件门禁贡献该策略。（本 Agent Note 最初提议带有 `read`/`write`/`edit` 方法的具体 `ctx.fileContext` 服务；[事件门禁 Agent Note](../architecture/2026-06-26-file-context-as-event-gate.md) 将其细化为本文所述插件，使工具永远不会在方法层与策略耦合。）
+
+观测状态以 `WeakMap<owner, Map<targetKey, FsVersion>>` 的形式存放于此。当且仅当 owner 读取、写入或编辑过该目标时，条目才存在（每次成功都会发出 `fs/observed`），因此条目的存在*本身就是*先前观测的记录——没有单独的 `hasRead` 标志。owner 从不透明的事件 actor（`{ agent?: { session? } }`）结构化派生，该形状定义在 `dsh-fs-policy` 中而非 `dsh-fs` 中。
+
+该插件决定三个 `fs/*` 事件：
+
+- `fs/write-intent`——无先前观测 ⇒ `{ kind: 'createIfAbsent' }`（只有新文件可以盲创建）；有先前观测 ⇒ `{ kind: 'replaceIfVersion', version: vObserved }`（已有文件仅在自观测以来未变时才替换）。单槽决策；不调用 `next()`。
+- `fs/edit-intent`——要求 owner 有先前观测（否则 `FS_NOT_OBSERVED`）；返回 `{ version: vObserved }` 作为 CAS 基础。它不实现字面替换——它授权并提供版本，提供方的变更临界区负责应用守卫，因此基于同一观测版本的并发编辑仍然是一赢一陈旧。
+- `fs/observed`——在成功的读取/写入/编辑后，为该 owner+target 记录 `{ version }`。同步、仅副作用的 `WeakMap.set`。
+
+该插件不做任何文件系统 I/O：「你是否观测过此文件？」是一次 `WeakMap` 查找，而「你读取的版本是否仍然是当前版本？」在 `ctx.fs.editText`/`writeText` 内部、与执行变更相同的原子锁中决定——插件只提供 `vObserved` 作为基础。
+
+## 工具契约
+
+`dsh-tool-fs` 保持相同的 schema 和提示词表面。`read` 仍然暴露 `file_path`、`offset` 和 `limit`；`write` 和 `edit` 不变。它是执行器：验证模型参数，通过 `ctx.fs` 直接读取/写入/编辑，拥有行窗口化和结果渲染（`N: text`、页脚、`<path>/<content>` 信封），并分发 `fs/*` 事件。
+
+每个变更操作先分发其 intent waterfall（瀑布式事件），带有 `undefined` 裸提供方默认值，然后调用 `ctx.fs`，再发出 `fs/observed`。例如 `write` 执行 `ctx.waterfall('fs/write-intent', target, exec, () => undefined)` → `ctx.fs.writeText(target, content, intent)` → `ctx.emit('fs/observed', …)`。`read` 先 stat 一次，然后读取/流式读取，构建窗口，最后发出 `fs/observed`。将 `exec` 作为 actor 传递，让 `dsh-fs-policy` 无需工具深入策略即可派生 owner。
+
+由于策略通过带有 `undefined` 默认值的事件贡献，`dsh-tool-fs` 不与 `dsh-fs-policy` 产生方法耦合：在插件缺席时，每个 intent waterfall 都落到 `undefined`（无条件裸提供方写入/编辑），`fs/observed` 没有监听器。加载插件后即可叠加读后写/编辑策略。
+
+## 并发边界
+
+进程内更新是安全的：本地后端保持既有的按目标变更锁，因此版本检查-然后-rename 是串行化的，失败的更新会看到 `FS_STALE_VERSION`。
+
+进程内创建由同一个按目标变更锁保护：两个调用者以 `createIfAbsent` 竞争时串行化，一个创建成功，另一个看到目标已存在并收到 `FS_NOT_OBSERVED`。跨进程创建仅为尽力而为；本地的 stat-then-rename 守卫无法在所有未来后端上提供可移植的排他创建保证。
+
+跨进程写入是尽力而为的新鲜度加原子替换：`mtime:size` 通常能捕获编辑器保存，但同一 tick 相同大小的写入可能遗漏；原子的 temp+rename 防止文件撕裂但不能防止所有丢失更新。
+
+## 取代
+
+本 Agent Note 推翻[文件系统能力 seam](../architecture/2026-06-17-filesystem-capability-seam.md)中的两项决策，并收窄第三项：
+
+- 读后写/编辑策略从 `ctx.fs` 移出，进入 `dsh-fs-policy` 插件（通过 `fs/*` 事件门控）。
+- 文本读取不再返回后端编号的行记录或 `full`/`partial` 视图；授权基于版本新鲜度，因此窗口化读取在文件未变时即可授权编辑。
+- 字面编辑不再位于旧的 `applyEdit` API 之后（该 API 混合了后端变更与 seam 拥有的观测策略）。它作为 `editText` 保留为提供方原语，因为版本守卫 + 字面匹配 + 原子重写必须留在提供方的变更临界区内。
+
+保留的内容：接口/实现/消费方纪律、消费方不导入后端规则、后端定义的 target/version/display 元数据、原子本地写入，以及共享的 `FsError` 分类体系。
+
+## 验证
+
+`dsh-fs` 精确暴露 `resolve`/`stat`/`readText`/`streamText`/`writeText`/`editText`（`stat` 返回 `FsInfo | undefined`，`writeText` 接受 `FsWriteIntent`），已删除的类型/原语不再存在；`dsh-fs-local` 不包含行、视图或 `formatReadBody` 逻辑；面向模型的 schema 保持逐字节不变。测试固定了以下行为：窗口化读取授权对未变文件的后续编辑；基于陈旧读取的编辑在尝试字面匹配之前报告 `FS_STALE_VERSION`；版本 CAS 行为得以保留；观测契约成立（`read` 工具的读取记录观测状态；直接 `ctx.fs` 读取不记录）；`dsh-fs-policy` 具有 HMR（热模块替换）/dispose（资源释放）覆盖率。
+
+## 后续扩展
+
+后来，[为文件系统 seam 添加直接目录列表](../architecture/2026-07-03-filesystem-directory-listing-seam.md)进一步扩展了该 seam。该后续工作单独跟踪，使本 Agent Note 的验收标准继续描述最初落地的 fsspec 风格改造。
+
+## 曾考虑的替代方案
+
+- **字节级 fsspec（`cat`/`open` 返回原始字节）**：否决。该 seam 刻意定位为文本存储，比字节级高半个层次，这样 UTF-8 解码、二进制/NUL 拒绝和受保护的文本变更只在提供方实现一次，策略层从不接触原始字节，也不将陈旧检查与变更临界区分离。
+- **具体的 `ctx.fileContext` 方法服务**——本 Agent Note 最初的策略形状；[事件门禁 Agent Note](../architecture/2026-06-26-file-context-as-event-gate.md) 将其重做为门禁插件，使工具永远不会在方法层与策略耦合。
+- **在提供方保留 `readPage` 和 `full`/`partial` 视图授权**：「取代」一节所逆转的重构前形态。视图完整性不是编辑安全所需的，版本新鲜度才是；而视图规则使超过读取上限的大文件无法编辑。
+
+## 后果
+
+- 新增第四个 fs 包和一个新的插件层。这是有意为之：它是此前推迟的策略层，而非第二个抽象后端 seam。
+- 直接使用 `ctx.fs` 会绕过策略：直接 `ctx.fs.readText` 不发出 `fs/observed`，因此在默认策略下，后续 `edit` 会以 `FS_NOT_OBSERVED` 拒绝，直到通过 `read` 工具读取该文件。这一失败是显式且有文档记录的。
+- 大文件行窗口化从后端移至 `dsh-tool-fs` 中的 `read` 工具；文本解码和二进制拒绝留在 `ctx.fs.streamText` 中，因此这只是窗口化逻辑的迁移，而非第二套文本 IO 实现。
+- 将 `editText` 保留在提供方 seam 上意味着每个后端都必须实现字面替换契约。这是有意为之：该操作不是纯存储，但陈旧守卫 + 字面匹配 + 原子重写是必须保持在一起的单元，以确保正确的错误归因和并发行为。该契约应保持窄且仅限文本，以便未来后端可以原生实现或通过全文件重写实现。
+- 新鲜度允许在窗口化读取后进行全文件 `write`。这比旧的视图检查更弱，但避免了大文件无法编辑的问题；提示词引导仍然不鼓励盲目的全文件替换。

## Problem
The loop records every model token delta as a durable `assistant/chunk` session event AND emitted a parallel live `agent/stream-chunk` Cordis event carrying the identical data. In `packages/core/agent-loop/src/loop.ts` the two sat one line apart:

Remove `agent/stream-chunk` from the agent event taxonomy. The token stream is read off `session/event` as `assistant/chunk`, the same feed persistence and replay already use — `session/event` is the single live transcript stream (assistant chunks, turn/step boundaries, tool activity, todos).
-**Consumers.** The only production consumer that mattered — the ACP bridge (`dsh-acp`), the real editor-facing streaming surface — already renders `assistant/chunk` off `session/event`, never `agent/stream-chunk`, so it is unaffected. The stdio UI (`dsh-ui-stdio`, a disposable test REPL) was the sole live consumer; it already had a `session/event` listener (from the boundary migration), so its chunk rendering folded into that listener as an `assistant/chunk` case. Consolidating to one listener also removed a latent hazard: the `inReasoning` dim-SGR flag was previously shared across two separate listeners (`agent/stream-chunk` and `session/event`), so a chunk and a boundary racing on it had no defined order; a single listener over the append order makes the interleaving deterministic.
+**Consumers.** Persistence, replay, and interactive renderers consume the authoritative session stream directly. The [automation-only ACP bridge](2026-07-23-acp-automation-only-protocol.md) emits committed `assistant/message` text rather than raw chunks, so it needs neither event. No production consumer requires an `Agent`-first token mirror.

+# Agent Note: 停止将 token 流镜像为 agent 事件
+
+Status: implemented
+
+[English](2026-07-02-remove-stream-chunk-mirror.md) | 中文
+
+## 问题
+
+agent loop（智能体循环）将模型的每个 token delta 同时记录为持久的 `assistant/chunk` 会话事件，并发射一个携带相同数据的并行实时 `agent/stream-chunk` Cordis 事件。在 `packages/core/agent-loop/src/loop.ts` 中，二者仅相隔一行：
+
+```ts ignore-check
+const chunkEvent = session.append('assistant/chunk', { turn, step, chunk })
+chunkSeqs.push(chunkEvent.seq)
+ctx.emit('agent/stream-chunk', agent, turn, step, chunk) // ← the mirror
+```
+
+- 持久事件：`assistant/chunk: { turn, step, chunk }`。
+- 实时发射：`agent/stream-chunk(agent, turn, step, chunk)`——相同的 `StreamChunk`，相同的 `turn`/`step`。
+
+实时发射相比会话事件唯一多出的东西是实时的 `Agent` 句柄，而唯一的消费方直接丢弃了它（其处理函数签名为 `(_agent, _turn, _step, chunk)`）。
+
+这与[移除边界镜像](2026-06-20-remove-agent-boundary-mirror-events.md)为轮次/步骤边界消除的重复相同：消费方面对同一持久事实的两个真源，每次变更都必须同时触及两者。该 Agent Note（agent 决策记录）没有把分片流一并纳入，而是推迟处理（“`assistant/chunk` 持久化仍承载关键约束，所以以后可以将分片流作为镜像评估，但那是一项独立决策”）。本 Agent Note 就是那项独立决策。
+
+推迟所依赖的前提已经明确：分片持久化是权威的，且将保留。停止持久化分片、仅保留瞬态实时流事件的提案已被[否决](../../rejected/simplification/2026-06-20-assembled-assistant-messages-only.md)——高保真回放、部分失败的流以及快照回放都依赖持久化的 `assistant/chunk` 序列。因此 `session/event` 上的 `assistant/chunk` 是持久的、承重的 token 流，而 `agent/stream-chunk` 是它的纯冗余镜像。
+
+## 决策
+
+从 agent 事件分类体系中移除 `agent/stream-chunk`。token 流通过 `session/event` 以 `assistant/chunk` 的形式读取——持久化与回放已经使用的正是同一个序列。`session/event` 是唯一的实时 transcript（文本记录）流（assistant 分片、轮次/步骤边界、工具活动、todo）。
+
+**消费方。** 持久化、回放和交互式渲染器直接消费权威的会话流。[仅面向自动化的 ACP（Agent Client Protocol）桥接层](2026-07-23-acp-automation-only-protocol.md)发出已提交的 `assistant/message` 文本而非原始分片，因此两种事件它都不需要。没有生产消费方需要一个 `Agent` 优先的 token 镜像。
+
+## 范围
+
+移除：`agent/stream-chunk`。
+
+未触及：
+- `assistant/chunk`（持久会话事件）——权威 token 流，原样保留。本 Agent Note 移除的是实时镜像，而非持久化（移除持久化的提案已单独遭到拒绝——见上文）。
+- `agent/steering`——本决策未触及（它是控制信号，不是 token 流）。其持久孪生事件是 `steering/message`，镜像发射由其自身的后续 Agent Note 移除：[移除 `agent/steering` 镜像发射](2026-07-04-remove-agent-steering-mirror.md)。
+- `agent/status`、`agent/error`、`agent/created`/`agent/disposed`、`agent/queued`、`agent/session-start`——生命周期/控制事件，不是 transcript 数据，也没有持久副本。
+
+## 曾考虑的替代方案
+
+**移除持久化、仅保留瞬态实时流**——反向裁剪，已被[单独否决](../../rejected/simplification/2026-06-20-assembled-assistant-messages-only.md)：高保真回放、部分失败的流以及快照回放都依赖持久化的 `assistant/chunk` 序列。在此前提确定后，实时发射才是配对中冗余的那一半。
+
+## 后果
+
+插件不能再从 `Agent` 优先事件观察 token 增量。它需要订阅 `session/event`、过滤 `assistant/chunk`，并在需要时通过 `ctx.agents.get(session.id)` 直接查找对应的实时 handle。没有生产消费方需要在分片时刻取得实时 `Agent`；这与移除边界镜像所作的取舍相同，均可接受。

## Problem
-`ImageBlock` (`packages/llm/llm/src/types.ts`) had no production producer, and every consumer on every path DROPPED it: the deepseek adapter's serializer skipped image blocks (a documented MVP limitation), the pi-ai converter skipped them as unrepresentable, the ACP codec neither advertises image prompt capability nor forwarded image blocks outbound and REJECTS image prompt content inbound, and the compaction estimator charged a flat token constant and rendered `[image]`. An `ImageBlock` constructed then would silently vanish from the wire — the vocabulary advertised a capability no path honored, which is the silent-data-loss shape AGENTS.md's defensive patterns warn against. The only constructors anywhere were tests pinning the skip/drop/estimate branches.

+`ImageBlock`（`packages/llm/llm/src/types.ts`）没有任何生产环境的生产者，而每条路径上的每个消费方都将其丢弃：DeepSeek 适配器的序列化器跳过 image 块（这是文档中注明的 MVP 限制）；pi-ai 转换器因无法表示而跳过；压缩（compaction）估算器对其收取一个固定 token 常量并渲染为 `[image]`。ACP（Agent Client Protocol）独立地拒绝图像提示词内容。此时构造的 `ImageBlock` 会在提供方协议格式（wire format）上静默消失——词汇宣告了一种没有任何路径兑现的能力，这正是 AGENTS.md 防御性模式所警告的静默数据丢失形态。唯一的构造调用出现在测试中，用于覆盖 skip/drop/estimate 分支。
+
+## 决策
+
+移除 `ImageBlock`、其 map 条目，以及适配器和压缩中的 image 专用分支。在同一个变更中更新所属的词汇文档与生成的引用。未知扩展块仍然覆盖默认分支，ACP 继续独立于 harness 词汇拒绝入站的图像提示词内容。
+
+## 曾考虑的替代方案
+
+### 为什么不保留？
+
+当适配器和压缩支持 image 时，`ContentBlockMap` 可以重新引入。ACP 可以继续作为纯文本的自动化协议。保留一个唯一实现就是拒绝的核心类型，等于宣告一个不可用的对外服务接口；移除后，生产者会立即得到编译期错误。
+
+评审中记录的回退方案（假如评审决定保留该槽位）：保留 `ImageBlock`，但将所有静默跳过替换为显式拒绝，并在词汇文档中记录该策略——静默丢弃是唯一没有辩护者的状态。评审最终决定移除；此回退方案作为文档化的替代方案保留，以备该槽位在完整功能就绪之前回归。
+
+## 验证
+
+除 Agent Note（agent 决策记录）之外，没有任何地方构造 harness `ImageBlock`。ACP 独立的入站图像拒绝路径仍有测试；适配器、codec 和压缩的默认分支则使用插件定义的块类型覆盖。
+
+## 后果
+
+日后重新添加核心词汇类型需要同时改动多个包（package）——但这种协调变更本就是真正的多模态功能所需的形态（适配器映射与压缩定价），而当前并不存在需要保留的实现。

+# Agent Note: 移除 `GenerateOptions.prefill` 与 `ToolSchema.strict`——无端到端可用路径的请求旋钮
+
+Status: implemented
+
+[English](2026-07-04-drop-inert-request-knobs.md) | 中文
+
+## 问题
+
+两个请求契约旋钮贯穿了整条请求流水线，却都无法产生任何效果：
+
+- **`prefill`**（`packages/llm/llm/src/types.ts`）没有生产级的 setter：agent loop（智能体循环）组装的是 `model`/`system`/`tools`/`messages` 加 `sessionId`/`signal`，上下文压缩（context compaction）后端只追加 `maxTokens`；而且两个适配器都拒绝它：`packages/llm/llm-deepseek/src/serialize.ts` 和 `packages/llm/llm-pi-ai/src/adapter.ts` 各自在 `prefill` 非 undefined 时抛出 `LlmError('UNSUPPORTED')`。该字段的全部可观测行为就是两个 throw，各由一条适配器测试固定。DeepSeek 的 chat-prefix completion 是一个 Beta 功能，运行在两个适配器都未指向的 base URL 上。
+- **`strict`**（`ToolSchema`，同一文件）穿过了 `DefineToolOptions`/`defineTool`（`packages/core/tools/src/schema.ts`）、注册表的 `schemas()` 允许列表（`packages/core/tools/src/index.ts`）、deepseek 协议格式（wire format）映射（`packages/llm/llm-deepseek/src/serialize.ts`，其 wire-type 注释记录了 strict 模式需要适配器未使用的 `/beta` base URL）、`packages/llm/llm-pi-ai/src/adapter.ts` 中的逐工具 payload 修补逻辑，以及 tool-catalog 渲染器（`scripts/gen-tool-catalog.ts`）中的条件 `Strict:` 行。没有任何已发布的工具设置过它——在所有 `tool-*` 包的 src 和 `examples/` 中执行 `rg` 搜索，`strict:` 的生产者为零；唯一的 setter 出现在 dsh-tools 单元测试中。
+
+两个旋钮在适配器间是对称的，因此移除操作将它们从两个孪生适配器中一并剥离——[孪生适配器设计](../architecture/2026-06-13-twin-llm-adapters.md)不受影响。
+
+## 决策
+
+- 从 `GenerateOptions` 中移除 `prefill`，同时移除两个适配器的 UNSUPPORTED 守卫、固定抛错行为的测试、[core.md](../../../../docs/core-data-structures/core.md) 中的粘贴行，以及记录该拒绝行为的适配器 README 表格行。实操手册中的 UNSUPPORTED 指导（[adding-an-llm-adapter.md](../../../../docs/cookbook/adding-an-llm-adapter.md)）改为通用表述规则——提供方无法遵守的 `GenerateOptions` 字段应抛出 `LlmError(..., 'UNSUPPORTED')`——而不再以 prefill 为例。[内容块词汇 Agent Note（agent 决策记录）](../architecture/2026-06-11-content-block-vocabulary.md)的后果按照 [implemented/AGENTS.md](../AGENTS.md)，将 prefill 记录为由生产者门控，而不是已有归属。
+- 从 `ToolSchema`、`DefineToolOptions`、`defineTool`、`schemas()` 允许列表、deepseek 序列化分支及其 wire-type 字段，以及工具目录渲染器的 `Strict:` 行中移除 `strict`。pi-ai 的 payload 修补逻辑简化为对 pi-ai 自身逐工具 strict 默认值的无条件清除（pi-ai 在每个序列化的工具上打 `strict: false`；手写的孪生适配器不发送此字段，因此清除逻辑为保持协议格式对等而保留，由其序列化器测试固定）。setter 测试和 core.md 粘贴行已移除；`GenerateOptions` 与 `ToolSchema` 在 `scripts/type-equiv.manifest.json` 中保留各自的行，因为两个类型只是少了一个字段，本身仍然存在。
+
+本 Agent Note 刻意不触及 `temperature`、`stop` 或 `maxTokens`：两个适配器都会端到端遵守它们，而且它们自然是 `agent/request` 上修改请求的钩子插件首批目标。
+
+## 曾考虑的替代方案
+
+### 为什么不保留？
+
+「显式的 UNSUPPORTED throw 是诚实的契约行为」——但一个在两个孪生适配器中唯一的实现就是拒绝的旋钮，什么也没承诺；删除它反而升级了失败模式：意外的 setter 变成编译错误而非运行时 throw。「Strict schema 遵循是官方文档记载的提供方功能，且管道完整」——但一个旋钮在有已发布的工具设置它并且有端点兑现它之前，不构成产品表面；今天两者都不成立。它们各自随首个真实 producer 回归：`prefill` 随实现了 chat-prefix completion 的适配器（以及对不支持该功能的适配器的明确策略）一起回来；`strict` 随需要它的工具和 beta 端点方案一起回来。
+
+## 验证
+
+`rg prefill` 只返回 Agent Note 记录（本文及[内容块词汇 Agent Note](../architecture/2026-06-11-content-block-vocabulary.md)中由生产者门控的后果）；限定在工具 schema 范围内的 `rg strict` 只返回本 Agent Note、保留下来的 pi-ai 清理逻辑，以及 `strictEqual` 等无关正文。两个适配器的契约测试都能在没有守卫的情况下通过，pi-ai 修正仍会清理库的 strict 默认值——其 serializer 测试固定了线协议一致性。
+
+## 后果
+
+已发布的钩子桥接不设置任何请求字段，而请求变更插件（`agent/request` waterfall（瀑布式事件）监听器）使用的是 `temperature`/`stop`（保留且可用），而非适配器拒绝的字段。如果 chat-prefix completion 或 strict 模式成为产品功能，重新添加将随适配器/端点工作一起落地，届时契约能说明实际发生了什么，而不是「所有人都 throw」。

+# Agent Note: 移除未被消费的 web 观测接口——`providers-change` 事件与 status 方法
+
+Status: implemented
+
+[English](2026-07-04-drop-unconsumed-web-observation-surface.md) | 中文
+
+## 问题
+
+`WebService` 暴露了一组没有任何生产代码观测的观测接口：
+
+- **`web/providers-change`**（`packages/web/web/src/index.ts`）在每次提供方注册和 dispose（资源释放）时声明并发出，且每个注册 effect 的回滚 yield 被刻意排在 emit 之前，唯一目的是让抛出异常的 change listener 能回退注册。在该包自身的两个单元测试之外没有任何 listener（其中一个测试的存在仅仅是为了固定那个回滚顺序）。
+- **`searchStatus()` / `fetchStatus()` 与 `WebCapabilityStatus` 联合类型**（同一包）没有生产调用方：`dsh-tool-web` 直接通过 `ctx.web.search()`/`fetch()` 执行，并把不可用性呈现为 seam 在执行时抛出的结构化 `WebError` code（`packages/web/tool-web/src/search.ts`、`packages/web/tool-web/src/fetch.ts`）；唯一的 status 调用方是 web 包自己的测试。`packages/web/tool-web/README.md` 和 [architecture.md](../../../../docs/architecture.md) 中的正文声称工具“只读取聚合的 `searchStatus()`/`fetchStatus()`”——这种漂移之所以存续，只是因为没有机制对照调用位置检查正文。
+
+seam 自身的设计使这两个接口天然没有消费方：工具注册跟随产品 ENABLEMENT 而非提供方可用性（`packages/web/tool-web/src/index.ts`），提供方选择在执行时解析且从不缓存——因此没有需要失效的缓存、没有需要重算的注册集合、也没有调用方需要一个有别于「执行并路由结构化错误」的可用性探测。HMR（热模块替换）清理由 effect disposer 自身承载。
+
+这与[删除无人消费的 `llm/adapter-change` 事件](2026-06-20-drop-unconsumed-llm-adapter-change-event.md)相呼应；后者从 `LlmService` 移除了相同的通知形状、相同的 emit 前回滚机制和相同的监听器抛错测试。该 Agent Note（agent 决策记录）的保留/删除标准是：为可能面向用户的工具列表消费方保留 `tools/change`，删除启动时后端注册表信号。按这一标准，web 提供方注册表明确属于删除一侧；status 方法则是把同一判断应用于拉取表面，而非推送表面。
+
+## 决策
+
+移除注册表变更事件、聚合 status 方法与类型，以及它们的专属测试。提供方私有的 status 保留用于执行时选择。面向调用方的覆盖率现在断言成功执行或结构化的选择错误，web 文档描述该按需调用契约。
+
+## 曾考虑的替代方案
+
+### 为什么不保留？
+
+web seam Agent Note 刻意规定了两者——事件作为最小 HMR 可见性信号，status 方法作为工具的聚合诊断——未来也可以设想提供方状态面板。但同一 Agent Note 的其他选择让它们失去了生存条件：调用时派生选择和基于启用状态的注册，使任何消费方都不可能需要其中任一项；已发布工具展示了真实模式（执行并路由结构化错误）；发生漂移的 README 句子则表明承诺中的消费方从未出现。按照 AGENTS.md 所述“Agent Note 是提案，而非绝对真理”，代码后来证明提案中的这些部分超出了需要；未来的观察者应根据真实消费方的形状，重新引入它实际消费的最小信号或查询。
+
+## 验证
+
+除 Agent Note 历史外，不再存在 `providers-change`、`searchStatus`、`fetchStatus` 或 `WebCapabilityStatus` 拼写；目录保持新鲜（`verify-cordis-catalog` 为绿色）；注册/释放 HMR 安全性测试通过执行行为证明清理；tool-web README 和架构段落也描述了工具实际拥有的执行时错误路由契约。
+
+## 后果
+
+未来若有提供方选择器 UI 或诊断面板需要变更通知或 status 查询，它将重新添加自身所消费的最小接口；相同的判断及其反转条件已记录在 LLM（大语言模型）先例中。

-# Agent Note: Fold the stdio UI helper into the stdio app
-
-Status: implemented
-
-The later [redundant-agent removal](2026-07-20-remove-stdio-and-echo-agents.md) supersedes this package-placement decision and removes the folded package, app, and line-oriented surface entirely.
-
-## Problem
-
-The readline UI was a whole package (`@deepseek-ai/dsh-ui-stdio` under `packages/support/`) whose only runtime importer was the app package `@deepseek-ai/dsh-stdio-demo`. The examples reach the readline UI by loading the app, never by composing the helper themselves; every other repo reference was mechanical or descriptive surface that existed BECAUSE the package boundary existed — manifest and tsconfig entries, generated module-graph rows, dependency-graph and README rows, and doc comments naming the package. The ui group README recorded the support placement rationale ("exists chiefly for the examples and the coverage gate — `ui/` is reserved for surfaces shipped as product"), which left a standing tension: a shipped product app depending on a support package documented as NOT product surface.
-
-The boundary bought package metadata, workspace and tsconfig references, module-graph rows, README entries, and publint surface for a helper that is not independently swappable: the stdio app's front-door cluster always includes the readline UI, and nothing else can meaningfully consume it.
-
-## Decision
-
-At the time, the helper moved into `@deepseek-ai/dsh-stdio` as the terminal-channel plugin. `createStdioChat`, its `StdioRuntime` test seam, and its unit tests moved with it, keeping EOF handling, rendering, disposal, and piped-vs-TTY behavior under the per-file coverage gate without hijacking process globals. The module kept the named `name`/`inject`/`Config`/`apply` export shape consumed by the app mount, while the then-current Echo and REPL Loader smokes proved the composed tree and the plugin-shape suite pinned explicit `unwrapExports` behavior. The superseding removal note above owns the current package and example state.
-
-The earlier support helper package was removed: its manifest, tsconfig references, module-graph rows, and README rows disappeared, while the remaining documentation described the in-package module.
-
-## Alternatives considered
-
-### Why not promote it to `ui/` instead?
-
-Promotion would have resolved the support-vs-product mismatch while keeping the boundary — the right call only if the readline UI were an independently swappable integration or had a second composer, and the consumer census said neither. The structured ACP bridge stays its own package because it is the product protocol surface with its own contract and snapshot tiers; the readline helper is scaffolding for one app's front door. Re-extraction stays cheap pre-release: if a second product app wants the readline UI, split it back out then, with that consumer shaping the package contract.
-
-## Consequences
-
-- The stdio app owns its whole front door; a leaf `cordis.yml` still loads one app package and nothing changed shape for the demos.
-- A future standalone terminal UI that wants the helper as a package reintroduces it with that second consumer, rather than the repo keeping a boundary for hypothetical reuse.

## Problem
The merge-extensible vocabulary maps are designed to grow by declaration merging, and the codebase already states the admission policy on `TurnEndReasonMap` (`packages/core/session/src/types.ts`): a variant like `refusal` is "deliberately omitted until" an adapter or loop first emits it. Three declared vocabulary items violated that policy — each had no producer and no consumer, and two had not even a test:

+# Agent Note: 裁剪无生产者的词汇变体（块缓存提示、`agent` 消息来源、`continuation` 轮次触发器）
+
+Status: implemented
+
+[English](2026-07-04-prune-producerless-vocabulary-variants.md) | 中文
+
+## 问题
+
+可合并扩展的词汇映射表设计上通过声明合并来增长，代码库已在 `TurnEndReasonMap`（`packages/core/session/src/types.ts`）上明确了准入策略：像 `refusal` 这样的变体「在适配器或循环首次发出它之前，有意不纳入」。三个已声明的词汇项违反了该策略——每个都既无生产者也无消费方，其中两个甚至没有测试：
+
+- **`TextBlock`/`ToolResultBlock` 上的 `CacheHint` 及其 `cache?: CacheHint` 块字段**（`packages/llm/llm/src/types.ts`；图像块曾有第三个此类字段，已随图像块一同移除——参见[删除图像 Agent Note（agent 决策记录）](2026-07-04-drop-image-content-block.md)）。任何地方都没有构造带 `cache:` 的块——src、测试和文档粘贴均为空——两个适配器也都不读取 `.cache`：DeepSeek 的提示词缓存是自动的，因此适配器会从响应中映射出 `prompt_cache_hit_tokens`，却从不向请求中发送 hint。这是没有任何提供方能够遵守的 Anthropic 风格 `cache_control` 表面。
+- **`MessageSourceMap.agent`**（`{ kind: 'agent'; agentId: string }`，同一文件）。零个构造点，包括测试在内。它预期的生产者在实现时并未使用它：subagent 后端将父级的提示词发送给子级时不带 `source`，因此记录为 `{ kind: 'user' }`，通用信封渲染器在插值 `source.kind` 时也从未对其做路由。
+- **`TurnTriggerMap.continuation`**（`packages/core/session/src/types.ts`）。agent loop（智能体循环）在结构上不可能发出它——continuation 发生在一个轮次*内部*作为后续步骤，而非作为新轮次——循环只构造 `message` 和 `injection` 触发器。唯一的写入者是一个手工构建的测试 fixture（测试前置数据），它只需要一个任意的非消息触发器（`packages/support/llm-replay/tests/llm-replay.spec.ts`），`injection` 触发器同样满足需求；唯一的生产环境触发器读取方 ACP（Agent Client Protocol）桥接层只过滤 `kind === 'message'`。
+
+## 决策
+
+`CacheHint`、其 `cache?` 块字段、`agent` 消息来源变体和 `continuation` 轮次触发器变体均已删除：已发布词汇不再携带它们。llm-replay fixture 使用 `injection` 触发器（任何非 `message` 触发器都能满足其用途）。[core.md](../../../../docs/core-data-structures/core.md) 和 [session.md](../../../../docs/core-data-structures/session.md) 中的 type-equiv 粘贴与裁剪后的 map 匹配——两个符号仍保留在 `scripts/type-equiv.manifest.json` 中的行，因为每个 map 都只是少了一个成员而继续存在——并且[内容块词汇 Agent Note](../architecture/2026-06-11-content-block-vocabulary.md)的后果按照 [implemented/AGENTS.md](../AGENTS.md)，将 cache hint 记录为由生产者门控，而不是已有归属。
+
+每个变体在获得真正的生产者之日回归，这正是映射表设计的增长方式：缓存功能连同传输它的适配器一起重新添加 `cache`；subagent 归属连同打标的后端和路由它的消费方一起重新添加 `agent`；真正启动新轮次的自动续行功能连同发出它的插件一起重新添加 `continuation`。
+
+## 曾考虑的替代方案
+
+### 为什么不保留它们？
+
+[内容块词汇 Agent Note](../architecture/2026-06-11-content-block-vocabulary.md)曾把“cache hint……有了归属”列为设计后果，预留槽位也确实能表明意图。但空槽位是每个实现和消费方都必须考虑的契约表面（我的适配器是否必须遵守 `cache`？我的 renderer 是否必须路由 `agent` 来源？），而相邻 map 自身的 JSDoc 已经拒绝“无 emitter 先预留”——`refusal` 和 `max_turn_requests` 被点名为*首次有内容发出它们时*再添加的变体，而不是提前声明。让已经声明但无用的变体遵守同一标准，才能使词汇真正有意义：只要它位于 map 中，就必须有内容生产它。
+
+## 验证
+
+对 `CacheHint`、`agent` 消息来源拼写和 `continuation` 触发器拼写运行 `rg`，只会返回 Agent Note 记录（本文，以及[删除图像 Agent Note](2026-07-04-drop-image-content-block.md)对图像块自身 `cache` 字段的说明）；llm-replay fixture 使用 `injection` 触发器断言相同的重放行为；核心数据结构粘贴和 type-equiv 清单保持同步。
+
+## 后果
+
+操作行为没有变化——原本就没有内容能够构造这些值。镜像事件移除（[边界镜像 Agent Note](2026-06-20-remove-agent-boundary-mirror-events.md)、[流分片 Agent Note](2026-07-02-remove-stream-chunk-mirror.md)）只触及瞬态 `agent/*` 事件，从不触及持久词汇，因此不存在冲突。其他位置已经遵守准入策略：`rejected`、`prompt/blocked` 和 `hook/invoked`/`hook/result` 都有实时生产者——本 Agent Note 将同一门槛扩展到缺少生产者的三个变体。图像块自身的 `cache?` 字段归属[删除图像 Agent Note](2026-07-04-drop-image-content-block.md)，后者将其与该块一同移除；本 Agent Note 覆盖剩余块类型上的两个字段。

## Problem
The [fs seam split](2026-06-26-fsspec-style-fs-seam.md) moved read routing and policy out of the backend into `dsh-tool-fs` and `dsh-fs-policy`. Four pieces of surface kept the pre-split shape — populated on every call, read by nobody:

+# Agent Note: 从 fs seam 中移除只写字段与一个无效的路由旋钮
+
+Status: implemented
+
+[English](2026-07-04-prune-write-only-fs-surface.md) | 中文
+
+## 问题
+
+[fs seam 拆分](2026-06-26-fsspec-style-fs-seam.md)将读取路由与策略从后端移至 `dsh-tool-fs` 和 `dsh-fs-policy`。有四处接口保留了拆分前的形态——每次调用都填充，却无人读取：
+
+1. **`dsh-fs-local` 中的 `STREAM_MIN_SIZE` + `FsIoInternals.streamMinSize`**——*在本次变更之前已被「禁止硬编码可调参数」审计移除，该审计将路由阈值改为 `dsh-tool-fs` 的 `readStreamMinSize` 配置；此处记录是为了完整呈现整次清理。* 原始位置（`packages/fs/fs-local/src/fsio.ts`，从 `packages/fs/fs-local/src/index.ts` 重导出）：包括 fs-local 自身源码和测试在内，全仓库零读取者。后端没有读取路由——`readWholeText`/`streamWholeText` 是调用方自行选择的两个独立原语——真正的路由常量位于消费方（`packages/fs/tool-fs/src/read.ts`，与 `info.size` 比较）。同一个 10 MiB 事实的两份镜像；后端那份是死代码，且该旋钮的 JSDoc 声称提供一个实际不存在的「read routing」覆盖。
+2. **`FsTarget.inputPath`**（`packages/fs/fs/src/types.ts`）：每个后端和每个测试 mock 都必须为这个「仅供诊断」的字段编造一个值，而生产环境零读取者——策略插件和所有错误消息使用的是 `targetKey`/`displayPath`。`listDir` 的生产者暴露了语义上的摇摆：目录子项得到的是裸条目名，这不是任何人的「input」。
+3. **`FsEditOutcome.replacements` + `.replaceAll`**（`packages/fs/fs/src/types.ts`）：`replacements` 生产环境零读取者（单匹配策略本身保留——它由后端内部 `FS_AMBIGUOUS_EDIT`/`FS_EDIT_NOT_FOUND` 抛出来强制执行，错误消息保留了内部计数）；`replaceAll` 仅被 `packages/fs/tool-fs/src/edit.ts` 中的 `formatEditOutput` 读取——作为工具本身已持有的 `replace_all` 参数的回声。精简后，`FsEditOutcome` 变为 `{ version, before, after }`，与 `FsWriteOutcome` 中真正由后端发现的字段对齐。
+4. **`FileReadOutcome.limit` + `.version`**（`packages/fs/tool-fs/src/read-render.ts`）：由读取工具填充，但 `formatReadOutput` 只渲染 `offset`/`lines`/`totalLines`/`truncatedByBytes`，且 `fs/observed` 事件发射直接使用 `info.version` 而非 outcome 的副本。
+
+## 决策
+
+删除 fs-local 常量、其再导出和 `streamMinSize` 配置项（其余 `FsIoInternals` 配置项确实由原子写入测试使用）；从 `FsTarget` 删除 `inputPath`；将 `FsEditOutcome` 收窄为 `{ version, before, after }`，并把解析参数中的 `replaceAll` 传给 `formatEditOutput`；从 `FileReadOutcome` 删除 `limit`/`version`。[filesystem.md](../../../../docs/core-data-structures/filesystem.md) 中的粘贴、`packages/fs/fs/README.md`，以及不得不虚构已删除字段的测试 fake 都随类型一同收窄。
+
+## 曾考虑的替代方案
+
+### 为什么不保留？
+
+未来的权限/隔离层可能需要解析前的路径来生成错误文本——但它需要的是*请求*，每个调用点仍然持有请求。「替换了 N 处」可能成为面向模型的文本——这是一个需要时再设计的行为变更，且后端内部的计数为其错误消息而保留。读取页脚可能展示 `limit`——但页脚展示的一切已经可以从 `lines`/`totalLines` 推导。与此同时，每个现有和未来的后端（远程、原生）都必须编造无人消费的协议字段，每个测试 mock 都必须满足它们。
+
+## 验证
+
+已删除表面不复存在——`dsh-fs-local` 中的 `STREAM_MIN_SIZE`/`streamMinSize`、`FsTarget.inputPath`、`FsEditOutcome.replacements`/`.replaceAll`，以及 `FileReadOutcome.limit`/`.version`——而请求侧 `replaceAll`（`FsEditRequest`）和其他 outcome 类型上的版本字段保持不变；测试 fake 随类型一同收窄。`formatEditOutput` 在两个 `replace_all` 分支中生成的文本都没有变化，因此没有快照预期输出发生改动。
+
+## 后果
+
+后端不增加新义务，反而卸下了四个无人消费的字段。fs 发现功能（glob/grep 工具）涉及相同的 `dsh-fs` 类型文件——这是文本层面而非设计层面的重叠，可以机械地合并解决。

## Problem
`agent/steering` was the last remaining transient mirror of a durable session event. The loop's steering drain appends the durable `steering/message { turn, content, source }` and, on the very next line, emitted `agent/steering(agent, turn, content, source)` — the identical fact as a fire-and-forget event (`packages/core/agent-loop/src/loop.ts`, `drainSteering`). It had zero production listeners: the only subscriber anywhere was a loop regression test asserting the emit carried `source` — the same fact the durable event already records one line above.

+# Agent Note: 移除 `agent/steering` 镜像 emit
+
+Status: implemented
+
+[English](2026-07-04-remove-agent-steering-mirror.md) | 中文
+
+## 问题
+
+`agent/steering` 是最后一个仍存在的、对持久会话事件的瞬态镜像。agent loop（智能体循环）的 steering（中途引导）drain 逻辑先追加持久事件 `steering/message { turn, content, source }`，紧接着下一行就 emit `agent/steering(agent, turn, content, source)`——同一个事实以 fire-and-forget 事件的形式重复发出（`packages/core/agent-loop/src/loop.ts`，`drainSteering`）。它在生产环境中没有任何监听者：唯一的订阅方是一个 agent loop 回归测试，断言 emit 携带了 `source`——而这同一个事实已经由上一行的持久事件记录。
+
+`agent/steering` 以相同的 payload 重复了紧接其前的持久事件 `steering/message`。`agent/queued` 仍保留为纯瞬态信号，因为它在持久化之前触发，覆盖了可能在进入日志前被取消的工作。
+
+Steering 承载真实生产流量——钩子 bridge 的轮次延续决策通过 `inbox.steer()` 注入其理由，最终成为由钩子矩阵预期输出固定的持久 `steering/message` 事件——而这些消费方无一例外都观察持久事件。没有任何内容观察镜像。
+
+## 决策
+
+`agent/steering` 已从 agent 事件分类中移除：包括 `packages/core/agent/src/types.ts` 中的声明（以及其中实时事件 JSDoc 列表对它的提及）、`drainSteering` 中的 emit（当时已无用的 `ctx` 参数也随之移除）、`packages/core/agent/README.md` 中的表格行，以及循环伪代码块（`packages/core/agent-loop/src/loop.ts` 模块文档和 [architecture.md](../../../../docs/architecture.md)）中的 emit 行；Cordis 目录重新生成后不再包含它。唯一的回归测试改为在持久 `steering/message` 事件上固定来源保留行为——所固定的事实存在于日志上。
+
+三份已实现 Agent Note（agent 决策记录）曾说明保留该事件；按照 [implemented/AGENTS.md](../AGENTS.md)，每份记录都已修改并指向本文作为移除记录：包括[边界 Agent Note](2026-06-20-remove-agent-boundary-mirror-events.md) 的保留列表条目、[流分片 Agent Note](2026-07-02-remove-stream-chunk-mirror.md) 的范围条款，以及[事件域语义 Agent Note](../architecture/2026-06-30-event-domain-semantics.md) 的瞬态 emit 枚举。
+
+## 曾考虑的替代方案
+
+### 为什么不保留？
+
+“它是控制信号，不是边界”——但该分类的实际区分是镜像/仅实时，而非控制/边界，并且该事件确实是镜像。希望在入队时收到通知的消费方可以使用 `agent/queued`（及其 steering 标记）；希望在排空时收到通知的消费方，本质上是在要求获知 `steering/message` 被追加的时刻，而 `session/event` 会交付相同 payload 并附带持久性。遭拒绝的[退役轮次中途 steering Agent Note](../../rejected/simplification/2026-06-20-retire-mid-turn-steering.md)所捍卫的是 steering *功能*——`steer()`、持久事件、强制延续——本次移除不会触及其中任何一项。
+
+## 验证
+
+`agent/steering` 拼写只存在于 Agent Note 正文中（本 Agent Note、上方三份已修改 Agent Note，以及已冻结的[遭拒绝 steering 功能 Agent Note](../../rejected/simplification/2026-06-20-retire-mid-turn-steering.md)，其正文记录了它所否决的提案）；目录已重新生成；重新定向的测试在 `steering/message` 上固定来源保留行为。
+
+## 后果
+
+生产环境中没有需要迁移的监听者，两种瞬态通知需求各有归宿：入队时由 `agent/queued`（带 `steering` flag）承载，drain 时由 `session/event` 在持久事件 `steering/message` 落地时承载。

## Problem
The stdio and ACP bins duplicated environment loading, fail-loud handling, entry validation, and boot logic, including subtle Loader failure behavior. Their copies had already drifted and lived in self-executing files excluded from unit coverage, making their helper exports unusable.

+# Agent Note: 共享应用 bin 的启动胶水代码，而非维护两份副本
+
+Status: implemented
+
+[English](2026-07-04-share-app-bin-boot-glue.md) | 中文
+
+## 问题
+
+stdio 和 ACP（Agent Client Protocol）两个 bin 各自重复了环境加载、fail-loud 处理、入口校验与启动逻辑，包括微妙的 Loader 失败行为。两份副本已经发生漂移，且位于自执行文件中、被排除在单元测试覆盖率之外，导致其导出的辅助函数无法被复用。
+
+## 决策
+
+辅助函数只存在一处：[`@deepseek-ai/dsh-app-boot`](../../../../packages/ui/app-boot)（`packages/ui/app-boot`，归入 `ui` 分组，因为 bin 是已发布产物，其运行时依赖本身也必须是已发布的包，而非 `support/`）。包含：`resolveConfigPath`（快照感知，两个 bin 共用的唯一路径解析器）、`loadEnv`、`installFailLoud`、`assertEntriesLoaded` 与 `boot`，每个函数都通过 bin 的诊断前缀参数化，并在其副作用 seam（warn sink、process slice）处支持注入，使单元测试套件能覆盖每个分支——包括 `boot()` 在进程内驱动真实 Loader、使用相对路径 specifier 配置的场景，既覆盖已稳定树的正常路径，也覆盖无 fiber 入口的拒绝路径。该包启用逐文件 100% 覆盖率门禁；Loader 失败的相关知识只有一个归属地。
+
+每个 `bin.ts` 都是在共享辅助函数之上加应用特有生命周期的精简自执行组合（ACP bin：重放模式环境变量跳过和 stdin EOF 释放；stdio bin：没有额外逻辑）。这些 bin 仍排除在覆盖率之外且不导出任何内容；已发布产物守卫保持不变——按照“真实入口路径即已发布产物”的防御模式，已构建 bin 冒烟仍在具有 node_modules 形状的临时目录中用纯 node 运行每个 bin（现在也会符号链接 `ui/app-boot`），并继续断言缺失配置时以非零状态退出。[提取示例应用包 Agent Note（agent 决策记录）](../architecture/2026-06-20-extract-example-app-packages.md)中的 bin 归属事实已据此修改。
+
+## 曾考虑的替代方案
+
+### 为何不保留重复？
+
+这些 bin 当时被定位为归属相互独立的已发布产物，而新包会带来固定开销（清单、README、tsconfig 引用、publint 表面），与去重的行数相当。但创建 bin 的 Agent Note 从未权衡应用间共享——它把三份示例 `start.ts` 副本合并进 bin 后便止步于此；漂移是已经观察到的事实；覆盖率缺口的理由也独立于去重理由：这是仓库中唯一免受逐文件 100% 门禁约束的非平凡运行时逻辑。记录的后备方案（只将纯逻辑提取到各应用模块）会结束豁免，但会继续让相关知识拥有两个归属。
+
+## 后果
+
+- 启动胶水代码的变更（新增守卫、修复路径解析）只需落地一次，两个已发布 bin 自动继承；bin 之间不会再次漂移。
+- `dsh-app-boot` 保持轻量依赖（cordis + loader/include 对）——它是启动机制，不是应用表面积。
+- bin 自身的文件几乎是平凡的组合；所有含分支的逻辑都在覆盖率门禁之下。

+# Agent Note: 收紧 hook-protocol 契约——dialect、废弃字段、双重默认值与 lib 拥有的 `hook/result` 语义
+
+Status: implemented
+
+[English](2026-07-04-tighten-hook-protocol-contract.md) | 中文
+
+## 问题
+
+`dsh-hook-protocol`/bridge 契约中有四部分没有遵守 [subagent observe/enrich Agent Note（agent 决策记录）](../feature/2026-06-30-subagent-observe-enrich.md)记下的准则——后者因缺少消费方而删除 `agentType` 生命周期字段，以下各项没有通过同一检验：
+
+1. **`HookDialect` 的 `'native'` 变体**（`packages/hooks/hook-protocol/src/types.ts`）没有生产者——bridge 会标记 `'claude'` 和 `'codex'`；所有位置中唯一构造 `'native'` 的是该库自己的单元测试。字段自身的 JSDoc 将 `dialect` 定义为“运行它的 bridge”，而 native 不是 bridge：[拦截 seam Agent Note](../feature/2026-06-30-interception-seams.md) 记载 native 钩子不是一个包，并且“native 插件无需持久钩子日志即可使用类型化 Decision”；旗舰 native 插件实践示例恰好断言了这一点（完全没有 `hook/*` 事件）。
+2. **`HookOutput.suppressOutput`**（同一文件）被 codec 解析后在所有路径上均被丢弃：没有 bridge 分支处理它、没有合并 fold、没有 warn、没有 deferred-list 行——在所有「被解析但未兑现」的同类字段中它是唯一没有明确延期声明的（`updatedInput` → 一条 warn 日志加 [pre-tool-input-rewrite 提案](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md)；`systemMessage` → 一条 warn 日志加 README deferred 行；`continue`/`stopReason` → 一个 `TODO(hook-continue-false)` 锚点加 `'stop'` decision 记录）。从结构上看根本无物可抑制：钩子 stdout 从不进入任何 transcript（文本记录）（上下文仅通过 `additionalContext` 流入；日志只记录 `decision`/`stderrSummary`），因此钩子作者设置 `suppressOutput: true` 得到的是无声的空操作，且无任何警告。
+3. **`defaultTimeoutMs` 在两个 bridge 配置中以浮动字面量双重默认**——schema 的 `.default(600_000)` 加上一个 `?? 600_000` 回退（`packages/hooks/hooks-claude/src/index.ts`、`packages/hooks/hooks-codex/src/index.ts`），一个协议级常量在每个 bridge 中有两个归属地，两个 bridge 可能在共享默认值上悄然分歧。*提案最初的补救措施是彻底删除该旋钮，但被 no-hardcoded-tunables 审计所取代：审计保留了该旋钮作为 bridge 拥有的显式配置（并在旁边新增了 `stderrSummaryMaxChars`）；剩下要修的是字面量的归属地。*
+4. **`hook/result` 的语义存在于两个 bridge 中（各一份），而非拥有该事件的 lib。** `summarize()`——stderr 截断规则——在 `packages/hooks/hooks-claude/src/index.ts` 与 `packages/hooks/hooks-codex/src/index.ts` 中逐字节相同；decision 字符串规则 `output.decision ?? (output.continue === false ? 'stop' : 'pass')` 同样如此。然而 `dsh-hook-protocol` 声明了 `hook/result`、在文档中将 `stderrSummary` 描述为「已截断」却不拥有截断逻辑，记录了 decision 值却不拥有映射逻辑。如果某个 bridge 漂移（不同的上限、不同的回退），共享持久化事件的语义就会悄然分叉。
+
+## 决策
+
+`HookDialect` 是封闭的 bridge 集合：`'claude' | 'codex'`；`HookOutput` 移除了不受支持的 `suppressOutput`。`hook/result.durationMs` 保留为持久化的审计计时，仅在快照中做归一化。参考默认值各只存在一处：`DEFAULT_HOOK_TIMEOUT_MS` 与 `DEFAULT_STDERR_SUMMARY_MAX_CHARS`。`HookResultRecord` 与 `appendHookResult` 为两个 bridge 统一拥有 stderr 摘要化和 decision 推导逻辑。`BLOCKING_EXIT_CODE` 为 codec 内部常量。
+
+## 曾考虑的替代方案
+
+### 为什么不保留它们？
+
+不受支持的词汇可以在真正有消费方时回归。`durationMs` 保留，因为持久化的审计计时独立于当前是否有读取方而有价值。Bridge 特有的 payload 构造留在各自 bridge 中，而共享持久化事件的归一化属于协议库。
+
+## 验证
+
+`HookDialect` 仅包含 Claude 和 Codex，`suppressOutput` 在源码、已解析字段文档和归一化逻辑中均不存在。`durationMs` 保留在事件和 fixture（测试前置数据）中，回放时做清洗。`600_000` 和 `500` 两个默认值各只在协议库中出现一次；每个钩子的超时覆盖仍然生效；两个 bridge 的测试套件均验证了由库拥有的 stderr 截断和 decision 规则。
+
+## 后果
+
+`dialect`、`suppressOutput`、可调参数和语义变更在线协议和预期输出中均不可见。代价是 `dsh-hook-protocol` 和两个 bridge 中的改动——在预发布立场下成本很低，也比让一项持久事件语义的两个副本各自老化更便宜。

+> The handshake-identity simplification remains current. The generic-card fallback was removed when [ACP became automation-only](2026-07-23-acp-automation-only-protocol.md); UI transports retain the provider-neutral presentation contract.
+
## Problem
Two pieces of `dsh-acp` surface were unreachable from any shipped configuration:
-1. **`AcpConfig.agentName` / `agentVersion`** (`packages/ui/acp/src/index.ts`). The shipped app package hands the bridge only `{ model }` (`packages/examples/acp-demo/src/index.ts`), so no leaf `cordis.yml` — the only production config surface — could set the knobs at all; they were settable solely by direct-mounting the bridge, which only a unit test did. Every snapshot expected output — the hook-matrix scenarios included — pins the schema defaults (`deepseek-harness-acp` / `0.0.1`). The pair also carried a live `TODO(double-default)`: the literals existed twice (schema `.default(...)` plus `??` fallbacks), with the TODO asking to pick one home.
+1. **`AcpConfig.agentName` / `agentVersion`** (`packages/acp/acp/src/index.ts`). The shipped app package hands the bridge only its agent target (`packages/examples/acp-demo/src/index.ts`), so no leaf `cordis.yml` — the only production config surface — could set the knobs at all; they were settable solely by direct-mounting the bridge, which only a unit test did. Every snapshot expected output — the hook-matrix scenarios included — pins the schema defaults (`deepseek-harness-acp` / `0.0.1`). The pair also carried a live `TODO(double-default)`: the literals existed twice (schema `.default(...)` plus `??` fallbacks), with the TODO asking to pick one home.
2. **The `toolKindFor` name heuristic** (same file) special-cased `bash*`/`read*`/`write`/`edit*` tool names in the generic-fallback path. Since the [render-intent union](../architecture/2026-07-02-tool-render-intent-union.md), every first-party tool those arms matched ships its own `presentCall` carrying its kind, and the presenter-less production tools (`subagent`, `subagent_fork`) fell through to `other` anyway. The arms were production-reachable only when a tool declined to present its own call — a `presentCall` that THROWS (the containment fallback), or model arguments that fail the tool's schema so `defineTool`'s `presentCall` wrapper returns `undefined` (e.g. a `bash` call missing the required `description`) — and the bridge's own module doc states the design rule the heuristic violated: "the bridge never special-cases tool names".
## Decision
-Hardcode the existing handshake identity `{ name: 'deepseek-harness-acp', version: '0.0.1' }` at initialization and remove the unreachable config fields and duplicate defaults. Replace `toolKindFor` with neutral `'other'` at both presenter fallbacks. Normal first-party presentations are unchanged; malformed or failed presentations now render an honest generic card instead of inferring a kind from the tool name. Initialize tests and snapshots pin the handshake; only the malformed calls in `hook-codex-posttool-block` change fallback card kind.

+# Agent Note: 裁剪不可达的 ACP 桥接层表面——品牌配置项与 kind 嗅探回退
+
+Status: implemented

+
+> 握手标识简化仍然有效。通用卡片回退已随 [ACP 转为仅面向自动化](2026-07-23-acp-automation-only-protocol.md)一并移除；UI 传输层保留提供方无关的展示契约。
+
+## 问题
+
+`dsh-acp` 有两处对外表面在任何已交付的配置中都不可达：
+
+1. **`AcpConfig.agentName` / `agentVersion`**（`packages/acp/acp/src/index.ts`）。已发布应用包只向 bridge 传递其 agent 的提供方/模型目标（`packages/examples/acp-demo/src/index.ts`），因此没有任何叶子 `cordis.yml`——唯一的生产配置表面——能够设置这些配置项；只有直接挂载 bridge 才能设置它们，而这种做法只存在于一个单元测试中。每份快照预期输出——包括钩子矩阵场景——都固定 schema 默认值（`deepseek-harness-acp` / `0.0.1`）。这对配置项还带有一个尚未解决的 `TODO(double-default)`：字面量存在两次（schema `.default(...)` 加 `??` 后备值），TODO 要求为它们选择一个归属。
+2. **`toolKindFor` 名称启发式**（同一文件）在通用回退路径中对 `bash*`/`read*`/`write`/`edit*` 工具名做了特殊处理。自[render-intent 联合类型](../architecture/2026-07-02-tool-render-intent-union.md)以来，这些分支匹配到的每个第一方工具都自带 `presentCall` 并携带其 kind，而没有 presenter 的生产工具（`subagent`、`subagent_fork`）本来就落入 `other`。这些分支只有在工具拒绝自行呈现调用时才在生产中可达：`presentCall` 抛出异常（容错回退），或模型参数未通过工具 schema 导致 `defineTool` 的 `presentCall` 包装层返回 `undefined`（例如 `bash` 调用缺少必需的 `description`）。而桥接层自身的模块文档明确声明了该启发式所违反的设计规则："桥接层绝不对工具名做特殊处理"。
+
+## 决策
+
+在初始化时硬编码现有的握手标识 `{ name: 'deepseek-harness-acp', version: '0.0.1' }`，移除不可达的配置字段与重复默认值。最初的实现还在两个 presenter 回退处将 `toolKindFor` 替换为中性的 `'other'`；ACP 不再投影工具卡片，因此该回退已完全离开传输层。初始化测试和快照固定握手标识。
+
+## 曾考虑的替代方案
+
+### 为什么不保留？
+
+品牌配置可以在 app 包将其暴露给部署环境时再回来。从未知工具名推断呈现方式违反了 render-intent 契约；中性回退卡片还能为格式错误的调用和损坏的 presenter 保留原始输入。
+
+## 后果
+
+桥接层不暴露品牌配置项。UI 传输层拥有不做工具名推断的通用展示回退，而 ACP 不承载任何工具卡片表面。

+# Agent Note: 移除无消费方的 skill 提供方事件
+
+Status: implemented
+
+[English](2026-07-12-drop-unconsumed-skill-provider-events.md) | 中文
+
+## 问题
+
+skill（技能）注册表产出两个通知事件，但没有生产环境的监听方。生成的生产者/消费方矩阵以及对事件名的精确搜索表明，`skill/provider-added` 与 `skill/provider-removed` 仅出现在声明、emit 站点、测试、生成的 catalog 和行文中。
+
+skill 发现按需读取当前的提供方映射表，提供方注册时同步清除已完成的 catalog，而 await 后的版本检查阻止了陈旧的发现结果进入缓存。没有兄弟插件通过这些事件等待 skill 提供方——与之形成对比的是活跃的 `subagent/provider-added` 消费方，它容忍兄弟并发加载。
+
+`tools/change` 与 `system-prompt/change` 明确不在本提案范围内。既有的简化决策将它们保留为面向实时工具和提示词 UI 的有意观测点，且自引用的已挂载插件已在使用 `tools/change`。本提案同样不改动 `subagent/provider-added`/`removed`，因为 `tool-subagent` 有生产环境的生命周期消费方。
+
+## 决策
+
+skill 注册表不再声明和 emit 提供方成员变更事件。提供方的注册与 dispose（资源释放）仍为 effect 所有的直接状态变更，同步使已完成的 catalog 失效；查找与发现按需读取当前提供方映射表。测试通过提供方查找和收集到的输出来观察清理行为，而非依赖生命周期通知。
+
+生成式事件目录、API 目录和生产者/消费方矩阵均不再包含已删除通知。skill system Agent Note（agent 决策记录）和包文档改为通过其由 effect 直接拥有的状态与 cache 失效契约描述注册。
+
+## 曾考虑的替代方案
+
+**为未来插件保留 skill 提供方通知。** 第三方插件可能想观察提供方的可用性，但直接提供方注册与按需查找才是扩展契约；当前没有消费方需要推送信号。如果将来出现兄弟加载竞态，可以像 subagent 注册表那样，引入一个带有该消费方实际所需的身份与就绪语义的通知。
+
+## 后果
+
+生成的事件矩阵中不再有 `skill/provider-added` 或 `skill/provider-removed` 的行。skill 发现、直接运行时注册、提供方 effect 回滚/dispose、缓存失效与注册表查找清理保持不变；监听方触发的回滚随事件一起消失。`tools/change`、`system-prompt/change` 以及已被消费的 subagent 提供方生命周期事件不受影响。
+
+预发布消费方失去 skill 提供方观测点，但仍保留两种贡献 skill 的方式：直接运行时注册与提供方注册。未来若有消费方需要实时的提供方可用性信息，必须新增一个带有其实际所需的身份与就绪语义的专用通知。

## Problem
The web capability carries request/result/status values that every shipped implementation populates but no production consumer reads. `WebSearchResult.providerId` and `query` and `WebFetchResult.providerId` are result echoes; `tool-web` formats only content/sources/truncation or final URL/status/body/truncation, and no other runtime reads them. Search providers return `WebProviderStatus.reason`, but resolution checks only `available` and intentionally emits a generic unavailable diagnostic.

+# Agent Note: 裁剪 web seam 中未使用的字段
+
+Status: implemented
+
+[English](2026-07-12-prune-unused-web-seam-fields.md) | 中文
+
+## 问题
+
+web 能力携带的 request/result/status 值，虽然每个已交付的实现都会填充，但没有任何生产环境的消费方读取它们。`WebSearchResult.providerId`、`query` 与 `WebFetchResult.providerId` 是结果回显；`tool-web` 只格式化 content/sources/truncation 或最终 URL/status/body/truncation，没有其他运行时读取这些字段。搜索提供方返回 `WebProviderStatus.reason`，但可用性检查只看 `available`，并有意输出一条通用的不可用诊断信息。
+
+`WebFetchRequest.timeoutMs` 同样从未被生产调用方设置。`tool-web` 只提供 URL，使用工具定义的 timeout 加 `exec.signal` 作为调用方截止时间，并依赖本地提供方的配置默认值作为兜底。这个未使用的逐请求覆盖迫使 `web-fetch-local` 暴露 `maxTimeoutMs`、对两个 timeout 来源做 clamp，并为没有任何产品路径能选中的优先级规则编写文档和测试。`WebExecContext` 则是另一个单字段包装层：每个调用方分配 `{ signal }`，每个提供方立即解包 `exec?.signal`；不存在第二个执行控制字段。
+
+## 决策
+
+web seam 移除搜索/抓取结果中的 `providerId` 回显和搜索的 `query` 回显；调用方本身已持有请求和提供方选择信息。提供方以返回布尔值的方法暴露可用性。抓取请求不再有逐请求 timeout 或 `maxTimeoutMs` clamp；本地提供方保留其可配置的默认 timeout，工具保留自身的截止时间。提供方方法直接接收一个可选的 `AbortSignal`，而非单字段的 `WebExecContext` 包装层。
+
+所有 web 实现与面向模型的工具使用更精简的契约。接口/实现/消费方的包（package）拆分、提供方选择、来源引用、最终 URL/状态数据、截断报告与安全限制保持不变。
+
+## 曾考虑的替代方案
+
+**保留自描述结果、逐请求截止时间与可扩展的执行上下文对象。** 结果回显可以帮助通用遥测，请求级 timeout 可以帮助受信的程序化调用方，包装层则为未来的控制字段留出空间。但目前不存在这样的消费方或第二个字段；在每个提供方中携带重复的身份标识、第二套截止时间策略以及包装/解包管道，使当前契约更难实现和解释。如果遥测或逐调用预算控制到来，届时应当定义哪个截止时间优先、在哪里观测提供方身份，以及多个控制字段是否足以证明需要一个上下文对象。
+
+## 后果
+
+保留下来的每个 web request/result 字段，要么被生产代码消费，要么是执行提供方请求所必需的。工具可见的搜索/抓取输出、提供方回退、中止行为、可配置的 timeout 兜底、截断与引用仍然被覆盖，无需请求级 timeout 优先级分支或执行上下文包装层。
+
+预发布阶段的程序化调用方失去了结果来源回显和逐请求的抓取截止时间。提供方仍具备部署级可配置 timeout 并尊重取消信号，因此这次精简移除的是可配置性，而非安全边界。

+# Agent Note: 简化会话日志表示
+
+Status: implemented
+
+[English](2026-07-12-simplify-session-log-representation.md) | 中文
+
+## 问题
+
+会话日志维护着两种表示，其机制复杂度超出了消费方的实际需求：一个伪链表 surface 和自定义的请求头增量。
+
+`SurfaceManager` 同时在数组、seq map 和可变 `prev`/`next` 链接中存储相同顺序。生产代码从不读取任一链接：compact 的工具配对 balance 根据按 surface 顺序缓存的每个切点 balance 作答。替换已经使用 `indexOf`，因此链接并未使其主导操作成为常数时间。使用线性替换查找的 seq 数组具有相同的渐近替换成本，却只有一种表示需要验证。
+
+请求头子系统实现了一套自定义的系统/工具增量编解码器和传输决策层，尽管其契约声明增量只是编码优化，而非可重建性要求。在每个 agent loop（智能体循环）实例边界保留初始/恢复的完整快照，然后在该实例的组装头发生变化时写入一条规范的完整 `request/header`，即可保留回放能力，同时删除 `SystemDelta`、`ToolsDelta`、往返回退逻辑以及持久化的 `request/header-delta` 变体。编解码器专属的词汇随编解码器一起消失，并非因为其各分支本身无效。
+
+实现保留追加与替换 `sourceEventSeqs`、崩溃修复 provenance，以及所有 `SessionStartSource` 变体，因为这些字段承担审计/拦截职责，当前没有读取方并不能推翻这一点。
+
+## 决策
+
+`SurfaceManager.nodes` 是由事件序号组成的 `readonly number[]`；公共 `SurfaceNode` 形状、node 链接和 seq-to-node map 均已移除。内部替换 generation 信号保留。session-query 使用的完整 `foldSurface()` 读取会返回相同的数字数组表示和替换元数据，而无需让增量 manager 保留历史。工具配对 balance 和压缩使用事件序号与 surface 位置；由 compact 拥有的每切点 balance cache 不依赖 node 链接。
+
+请求头只使用规范的完整快照。初始与恢复锚点即使没有变化也仍是完整快照；实例内变化会追加另一个完整 `request/header`，reason 为 `change`。delta 事件、codec 类型、diff/apply 辅助函数，以及仅供 codec 使用的 `fallback` reason 均已移除。请求重建选择最新快照。
+
+`SESSION_FORMAT_VERSION` 仍固定为 `0`，因此 seed、追加和持久化加载验证会显式拒绝旧 v0 `request/header-delta` 事件，以及携带已删除 `fallback` reason 的完整快照。不存在兼容性 fold 或迁移。JSONL 与 SQLite 测试固定了这一响亮失败边界；ACP（Agent Client Protocol）快照 harness 则把合法的会话中途变更表示为完整固定请求头和完整可读提示词。
+
+## 曾考虑的替代方案
+
+**保留链表节点和紧凑增量以备未来扩展。** 链接可能有助于未来的游标 API，增量在大型工具 schema 仅有少量变化时可以缩减日志。但没有已发布的游标使用这些链接，而完整快照以磁盘空间换取了显著更简单的正确性。如果头部体积确实成为问题，可以基于真实 trace 设计压缩方案或经过度量的规范增量方案。
+
+## 验证
+
+单元覆盖率固定有序 surface 的追加/替换行为、工具配对、压缩、完整请求头 fold/记录、请求重建和开发不变量。Seed 验证以及 JSONL、SQLite 加载测试会在重放前拒绝旧事件。无密钥 ACP 套件以新形状覆盖记录、刷新、重放、变化请求头固定，以及沙箱模式切换 fixture（测试前置数据）。
+
+## 后果
+
+完整请求头会增加日志体积，线性替换查找在极大 surface 上也可能较慢。由于先前实现调用 `indexOf`，替换原本就是线性的；benchmark 推迟到真实 trace 表明更简单的数组成为瓶颈时再进行。格式版本仍为 `0`，因此显式拒绝旧事件是预发布格式边界的永久组成部分。作为交换，surface 顺序和请求头状态现在各自只有一种表示，删除了链接维护、map、codec 分支、往返 fallback 和感知 delta 的快照规范化。

-# Agent Note: Retire the readline front door and the repl-agent example
-
-Status: implemented
-
-English | [中文](2026-07-20-retire-readline-front-door.zh.md)
-
-## Problem
-
-The repo shipped two interactive terminal front doors: the line-oriented readline channel (`@deepseek-ai/dsh-stdio`) and the full-screen [`@deepseek-ai/dsh-tui`](../feature/2026-07-17-dedicated-full-screen-tui-front-door.md). After the TUI landed, readline's interactive role was redundant — `demo:tui` superseded `demo:repl` as the coding-agent experience — while its remaining real role, pipes and automation, was already served better by the one-shot `@deepseek-ai/dsh-cli-demo` app (task in, DSH-native `text`/`json`/`stream-json` out, durable persistence, signal handling).
-
-The duplication was structural, not just cosmetic: `dsh-stdio-demo` carried a `TerminalMode` (`auto`/`readline`/`tui`) selection seam, ~1,000 lines of readline unit tests, a readline transcript grammar (`[tool call] …` lines) that the CI demo smoke and two built-bin e2es grepped, and an inverted example composition where the flagship `tui-agent` leaf was defined as an include-patch over the `repl-agent` leaf it superseded.
-
-## Decision
-
-Delete the readline front door and the repl-agent example; keep exactly three front-door archetypes: **interactive TUI** (TTY-only, fails loud on pipes), **one-shot CLI** (`-p`/positional task, pipes and automation), and **servers** (ACP / JSON-RPC).
-
-- `packages/ui/stdio` and `examples/repl-agent` are gone. `packages/examples/stdio-demo` is renamed `@deepseek-ai/dsh-tui-demo` (`packages/examples/tui-demo`) and always mounts `dsh-tui`; the `TerminalMode`/`resolveTerminalMode`/`ui.mode` seam is deleted. The bin refuses non-TTY streams **before booting the Loader** (a compose-time throw inside a Loader tree is logged per-entry, not rethrown, so a piped launch would otherwise settle into an idle UI-less process instead of exiting nonzero).
-- `examples/tui-agent/cordis.yml` now owns the coding composition inline (the include-patch inversion is gone); its Code Mode overlay includes its own base. `examples/cordis-agent` moved to the TUI app.
-- `examples/echo-agent` moved to the one-shot `dsh-cli-demo` app; `dsh-cli-demo` gained `-p/--prompt` as the flag form of the single task (mutually exclusive with the positional).
-- The UI-independent with-key coding e2es (`full-loop`, `coding-task`, `resume`, `compaction`, `todo-write`, `code-mode` and their shared harness) moved verbatim from `examples/repl-agent/tests/` to `examples/tui-agent/tests/` — they assemble the stack programmatically and never touched a UI.
-- The SDK wizard's `stdio` run interface became `tui` (`RunInterface = 'acp' | 'tui' | 'embed'`), contributing a `dsh-tui` entry instead of `dsh-stdio`; the generated `index.ts` guards TTY before `startSDK` for the same pre-boot fail-loud reason as the tui-demo bin.
-
-### Testing policy: PTY only for the TUI
-
-Pipes remain the default test medium. PTY-driven subprocess tests are sanctioned **only** where the subject is the TUI itself: `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` (which gained the Code Mode overlay boot scenario, replacing repl-agent's pipe smoke as the overlay's keyless composition proof) and the minimal PTY boot smoke in `examples/cordis-agent` (whose front door IS the TUI). Everything else moved to pipes over the one-shot bin:
-
-- `examples/echo-agent/tests/echo.e2e.ts` proves the Loader boot + mock-model tool round-trip through `stream-json` records instead of readline transcript lines.
-- The CI demo-smoke gate (`scripts/run-gates.ts`, AGENTS.md) runs `demo:echo --output-format stream-json -p "echo ci smoke"` and parses the records structurally.
-- `packages/examples/tui-demo/tests/built-bin.e2e.ts` proves the built bin's piped-launch refusal (nonzero exit + pointer at `dsh-cli-demo`); the echo-round-trip-under-plain-Node and missing-config fail-loud proofs live in `cli-demo`'s built-bin suite.
-- `packages/context/time-context/tests/time-context.e2e.ts` runs one one-shot turn; multi-turn elapsed rendering stays unit-covered in its spec.
-
-## Accepted losses
-
-- **Piped multi-turn in one process** — the readline channel could script several turns over stdin; the one-shot bin runs one task per process. Multi-turn continuity is covered by `RESUME_SESSION_ID`/resume e2es and the TUI's scripted PTY conversation.
-- **Non-TTY `ask_user_question`** — the readline provider was the only non-TTY terminal implementation of `ctx.userInteraction`. A headless run whose model calls `ask_user_question` now fails that tool call (no provider); the ACP bridge remains the non-terminal provider. A future headless deployment that needs it composes its own provider.
-
-## Alternatives considered
-
-- **Keep `dsh-stdio` as a pipe/automation channel without the repl demo** — rejected: its automation role duplicated `dsh-cli-demo` with a weaker contract (unstructured transcript, EOF-exit heuristics vs. one durable turn ending and format-pure output).
-- **Rewrite the piped smokes as PTY drivers** — rejected: PTY is the flakier, more complex medium and is reserved for the one surface pipes cannot prove (real TTY takeover/restore).
-
-## Consequences
-
-- One interactive front door (TUI), one automation front door (one-shot CLI), two servers; no mode-selection seam in the terminal app.
-- ~1,000 lines of readline unit tests deleted with their behavior; the readline transcript grammar is gone from all gates.
-- This supersedes the packaging half of [fold the stdio UI helper](2026-07-04-fold-stdio-ui-helper.md) (the folded package is now deleted) and amends the composition described in [the TUI front-door note](../feature/2026-07-17-dedicated-full-screen-tui-front-door.md) (no `auto` selection; `tui-agent` owns the coding composition).

-## 问题
-
-仓库同时提供两个交互式终端前端：面向行的 readline 通道（`@deepseek-ai/dsh-stdio`）和全屏的 [`@deepseek-ai/dsh-tui`](../feature/2026-07-17-dedicated-full-screen-tui-front-door.md)。TUI 落地之后，readline 的交互角色已经冗余——`demo:tui` 作为编码 agent 体验取代了 `demo:repl`——而它剩下的真实角色（管道与自动化）已由单次任务的 `@deepseek-ai/dsh-cli-demo` 应用以更好的方式承担（任务输入、DSH 原生 `text`/`json`/`stream-json` 输出、持久化、信号处理）。
-
-这种重复是结构性的，不只是表面问题：`dsh-stdio-demo` 携带一个 `TerminalMode`（`auto`/`readline`/`tui`）选择接缝、约 1,000 行 readline 单元测试、一套被 CI 演示冒烟测试和两个 built-bin e2e 用 grep 匹配的 readline 文本记录语法（`[tool call] …` 行），以及一个倒置的示例组合：旗舰 `tui-agent` 叶节点被定义为对它所取代的 `repl-agent` 叶节点的 include patch。
-
-## 决定
-
-删除 readline 前端和 repl-agent 示例；只保留三类前端原型：**交互式 TUI**（仅 TTY，管道下快速失败）、**单次任务 CLI**（`-p`/位置参数任务，服务管道与自动化）以及**服务器**（ACP / JSON-RPC）。
-
-- `packages/ui/stdio` 与 `examples/repl-agent` 已删除。`packages/examples/stdio-demo` 更名为 `@deepseek-ai/dsh-tui-demo`（`packages/examples/tui-demo`）并始终挂载 `dsh-tui`；`TerminalMode`/`resolveTerminalMode`/`ui.mode` 接缝随之删除。bin 在**启动 loader 之前**就拒绝非 TTY 流（Loader 树内组合期抛出的异常按条目记录日志而不会重新抛出，管道启动否则会沉降为一个空闲的无 UI 进程而不是以非零码退出）。
-- `examples/tui-agent/cordis.yml` 现在内联拥有编码组合（include patch 倒置消失）；其 Code Mode 覆盖层 include 自己的基础配置。`examples/cordis-agent` 迁移到 TUI 应用。
-- `examples/echo-agent` 迁移到单次任务的 `dsh-cli-demo` 应用；`dsh-cli-demo` 新增 `-p/--prompt` 作为单个任务的旗标形式（与位置参数互斥）。
-- 与 UI 无关的带密钥编码 e2e（`full-loop`、`coding-task`、`resume`、`compaction`、`todo-write`、`code-mode` 及其共享 harness）原样从 `examples/repl-agent/tests/` 移入 `examples/tui-agent/tests/`——它们以编程方式组装整个栈，从不接触任何 UI。
-- SDK 向导的 `stdio` 运行接口改为 `tui`（`RunInterface = 'acp' | 'tui' | 'embed'`），贡献 `dsh-tui` 配置项而不是 `dsh-stdio`；生成的 `index.ts` 在 `startSDK` 之前检查 TTY，理由与 tui-demo bin 的启动前快速失败相同。
-
-### 测试策略：PTY 仅用于 TUI
-
-管道仍是默认测试介质。PTY 驱动的子进程测试**仅**在被测对象就是 TUI 本身时获准使用：`examples/tui-agent/tests/tui-keyless-smoke.e2e.ts`（新增 Code Mode 覆盖层启动场景，取代 repl-agent 的管道冒烟测试成为该覆盖层的无密钥组合证明）和 `examples/cordis-agent` 中最小的 PTY 启动冒烟测试（其前端就是 TUI）。其余全部改为通过单次任务 bin 走管道：
-
-- `examples/echo-agent/tests/echo.e2e.ts` 通过 `stream-json` 记录证明 Loader 启动 + mock 模型的工具往返，而不是匹配 readline 文本记录行。
-- CI 演示冒烟门禁（`scripts/run-gates.ts`、AGENTS.md）运行 `demo:echo --output-format stream-json -p "echo ci smoke"` 并结构化解析记录。
-- `packages/examples/tui-demo/tests/built-bin.e2e.ts` 证明构建产物 bin 对管道启动的拒绝（非零退出 + 指向 `dsh-cli-demo` 的提示）；纯 Node 下的 echo 往返证明与缺失配置的快速失败证明位于 `cli-demo` 的 built-bin 套件。
-- `packages/context/time-context/tests/time-context.e2e.ts` 运行一个单次任务轮次；多轮 elapsed 渲染仍由其单元测试覆盖。
-
-## 接受的损失
-
-- **单进程内的管道多轮对话**——readline 通道可以通过 stdin 脚本化多个轮次；单次任务 bin 每个进程只运行一个任务。多轮连续性由 `RESUME_SESSION_ID`/resume e2e 和 TUI 的脚本化 PTY 对话覆盖。
-- **非 TTY 的 `ask_user_question`**——readline 提供方是 `ctx.userInteraction` 唯一的非 TTY 终端实现。模型调用 `ask_user_question` 的 headless 运行现在会让该工具调用失败（没有提供方）；ACP 桥接仍是非终端提供方。未来需要它的 headless 部署自行组合提供方。
-
-## 曾考虑的替代方案
-
-- **保留 `dsh-stdio` 作为纯管道/自动化通道而只删 repl 演示**——不予采纳：它的自动化角色以更弱的契约重复了 `dsh-cli-demo`（非结构化文本记录、EOF 退出的启发式判断，对比后者的一次持久轮次结束和格式纯净输出）。
-- **把管道冒烟测试改写为 PTY 驱动**——不予采纳：PTY 是更易波动、更复杂的介质，仅保留给管道无法证明的那一个表面（真实 TTY 的接管/恢复）。
-
-## 后果
-
-- 一个交互式前端（TUI）、一个自动化前端（单次任务 CLI）、两个服务器；终端应用不再有模式选择接缝。
-- 约 1,000 行 readline 单元测试随其行为一起删除；readline 文本记录语法从所有门禁中消失。
-- 本决定取代 [fold the stdio UI helper](2026-07-04-fold-stdio-ui-helper.md) 的打包部分（被折叠的包现已删除），并修订 [TUI 前端 Agent Note](../feature/2026-07-17-dedicated-full-screen-tui-front-door.md) 描述的组合（不再有 `auto` 选择；`tui-agent` 拥有编码组合）。

The first plan-mode implementation introduced a generic named-mode registry even though the product shipped only `plan`. `ModeConfig.modes`, definition-name validation, `ctx.modes.list()`, retired-definition fallback, and a synthetic `review` mode in tests existed only to support hypothetical future collaboration modes. The production-specific behavior—plan guidance, `/plan`, and `exit_plan_mode`—still lived in the same package, so the generic API did not isolate a reusable mechanism from plan policy.

Treating both as instances of one named-mode abstraction would obscure their independent ownership. ACP's protocol happens to expose a generic mode picker, but that is an adapter vocabulary rather than evidence that the harness needs a generic mode domain.

Bare `/plan` selects active; another non-empty argument selects it first and then sends the trimmed text through `agent.steer()`, making the text an ordinary logged user message in the affected step. `/plan off` selects inactive without model input and can cancel an entry that is still pending at the boundary. The exit tool remains registered while plan mode is inactive so the request tool catalog stays stable.
-ACP keeps its protocol-level `default` and `plan` ids. The bridge maps those two ids to the boolean service, advertises only that fixed pair, rejects every other id at the adapter boundary, and maps committed `plan/mode` events back to `current_mode_update`. The protocol remains generic without forcing genericity into the product domain.
+Human-facing compositions own plan selection and review. This note originally kept ACP's protocol-level `default`/`plan` picker as an adapter over the boolean service; [ACP as an automation-only protocol](2026-07-23-acp-automation-only-protocol.md) supersedes that wire projection, so the ACP composition now mounts neither plan mode nor a mode-selection protocol.
Sandbox mode and approval policy remain separate enforcement axes. Plan mode neither reads nor writes them, and the simplification introduces no shared base type, registry, or preset abstraction across those concepts.
+### Boundary and model contract
+
+`plan/mode` is log-only and non-surface, so resume, fork, and compaction recover the state without a live mirror. A spawned agent begins inactive because there is no creation-time plan option. Pending user selections flush before the affected request assembly on prompt submission, ordinary continuation, or a request-recovery retry; a failed durable append leaves the intent pending for a later boundary.
+
+The active state contributes the deployment's section at prompt order 50. Inactive state contributes no section, while `exit_plan_mode` remains registered in both states, so a transition changes the logged request header but not native tool schemas or the Code Mode SDK. A user-driven transition appends one plugin-sourced notice only when the last request header described the opposite state; a pre-first-request or net-zero selection adds none, and an approved tool exit relies on its tool result instead of a second notice.
+
+### Reviewed exit
+
+`exit_plan_mode` requires a calling agent in active plan mode and a non-empty markdown plan beginning with a heading. The user-interaction question carries that exact plan as detail and offers `Approve` or `Keep planning` plus free-text feedback. Only one `Approve` selection with no custom text consents; every other answer stays in plan mode and returns corrective feedback to the model. An approved exit becomes a silent pending selection, leaving plan guidance active for the rest of the current tool batch and removing it before the next request.
+
+The tool renders the submitted plan as a generic card titled by its first heading. An absent or failed user-interaction provider, a failed review, or plugin disposal while review is pending fails closed and leaves manual `/plan off` as the human escape path.

## Verification
- Package tests retain boundary ordering, retry, append-failure, HMR disposal, prompt assembly, stable native and Code Mode schemas, review outcomes, and invariant coverage through the boolean service.
- Command tests cover bare `/plan`, `/plan <message>`, active `/plan off`, pending-entry cancellation, inactive idempotence, absence of `/mode` and `/review`, and effect-scoped removal.
-- ACP tests cover fixed advertisement, both ids, unknown-id rejection, optimistic updates, committed exits, and load replay.
- The keyless TUI scenarios enter through `/plan <message>`, leave through `/plan off`, and prove that each committed `plan/mode` precedes the request header it changes, the entry message is logged under plan guidance, and the post-exit request omits that guidance.
+- The complete `exit_plan_mode` review arc is package-tested but has no assembled-application snapshot after the interactive ACP scenarios were retired; current keyless TUI scenarios cover command entry and direct exit only.
## Consequences
-The implementation has one vocabulary for one shipped feature. Adding another collaboration stance is now an explicit design decision instead of a config entry, while ACP clients continue to see their standard mode picker. The migration intentionally rejects old `mode/set` logs and old `modes.plan.section` configuration under the repository's pre-release format policy.

## Problem
-Two model-title implementations coexisted after the tui-staging line merged onto master. The TUI carried its own `autoTitle` feature: a fire-and-forget `ctx.llm.stream` call after the first user message that set the terminal window title via OSC 0, with a one-shot latch, its own prompt, its own 40-character cap, and its own resume re-derivation ([auto-title Agent Note](../feature/2026-07-21-tui-auto-pane-title.md), [default-on Agent Note](../feature/2026-07-21-tui-auto-title-default-on.md)). Master had meanwhile landed [log-backed session titles](../feature/2026-07-21-log-backed-session-titles.md): a `sessionTitle` capability whose accepted revisions are durable `session/title` events, with a deterministic fallback and optional model providers. The TUI already consumed `session/title` for its header subtitle and window title, so a session could be titled twice by different strategies, and the TUI's process-local title was invisible to every other consumer (ACP, resume listings, forks).
+A per-session title makes terminal panes and tabs distinguishable, but a TUI-local model call would create a second title pipeline beside [log-backed session titles](../feature/2026-07-21-log-backed-session-titles.md). The local path needs its own prompt, cap, one-shot latch, resume derivation, cancellation, and failure fallback, while its process-local result remains invisible to session listings, forks, Web consumers, and replay. If both paths run, one session can also be titled twice by different strategies.
## Decision
-The TUI-local generation is removed; the session-title service is the one title source. `TuiConfig.autoTitle`, the latch, the abort controller, the title prompt, and `titleLine` are gone from `dsh-tui`. The terminal rename stays: the TUI folds the latest logged title on mount (`foldSessionTitle`), renders it as the banner subtitle, and sets the terminal window title to `<session title> — <configured title>` on every accepted `session/title` event — including resumed sessions, whose titles now replay from the log instead of being re-generated.
+The session-title service is the one title source. The TUI contains no `autoTitle` config, title-model request, latch, abort controller, prompt, or output cap. It folds the latest logged title on mount (`foldSessionTitle`), renders it as the banner subtitle, and calls `runtime.terminal.setTitle` with `<session title> — <configured title>` on every accepted `session/title` event. The same terminal-safe OSC 0 path handles the configured fallback title, resumed sessions, and live revisions without renaming tmux windows or adding another terminal-control surface.
Model-made titles are a composition choice: `examples/tui-agent/cordis.yml` (and the scripted PTY fixture) mount `@deepseek-ai/dsh-session-title-first-message-llm`, which inherits the main request's route and replaces the spine's deterministic fallback with a short model summary. Deployments without the provider keep the fallback title from `dsh-agent-spine-demo`'s bundled `SessionTitleService`.

+## Verification
+
+TUI tests pin restored and live `session/title` consumption, terminal-safe title rendering, the configured fallback, and the absence of a TUI-owned model path.

## Consequences
-One title pipeline: durable, replayable, visible to every consumer, and fenced against stale completions by the service. The TUI sheds ~90 lines and its `llm`-streaming path. The cost is that a title now requires the provider plugin in the composition for model quality — a leaf choice, not a TUI default — and the terminal title changes shape from the bare model summary to the suffixed `<title> — <product>` form the log-backed path always used. The superseded auto-title Agent Notes carry pointers here.

+# Agent Note: ACP as an automation-only protocol
+
+Status: implemented
+
+English | [中文](2026-07-23-acp-automation-only-protocol.zh.md)
+
+## Problem
+
+The ACP bridge had become a second interactive product UI. It translated durable events into editor cards, terminal metadata, diffs, plans, titles, reasoning, commands, modes, model and permission pickers, session navigation, and human elicitation. Those responsibilities duplicated the TUI and the Web client while coupling an automation transport to UI services, persistence queries, presentation policy, and editor-specific conventions.
+
+ACP still has one useful role: another agent or automated controller can start a harness process, create an isolated session, send text, receive the committed answer, cancel work, and answer a permission request. The out-of-process ACP subagent backend depends on that standard protocol boundary.
+
+The snapshot suite complicates removal. Most ACP scenarios exercise the assembled agent backend rather than ACP presentation, so deleting the suite with the editor bridge would discard broad keyless behavioral coverage.
+
+## Decision
+
+`@deepseek-ai/dsh-acp` is an automation transport under [`packages/acp/acp`](../../../../packages/acp/acp/README.md), outside the `ui` package group. Its public protocol is intentionally small: version negotiation, fresh text sessions with one in-flight prompt each, committed assistant text updates, per-session cancellation, concurrent sessions, and connection-owned teardown. Prompts carry the spec-required baseline only — text plus resource links flattened to bracketed textual references; the bridge rejects additional directories, MCP servers, beyond-baseline prompt content (image, audio, embedded resources), empty prompts, unknown sessions, and overlapping prompts.
+
+The bridge emits only committed `assistant/message` text. Reasoning, raw chunks, tool activity, todos, plans, titles, retry markers, terminal metadata, diffs, locations, and resource links remain in the durable session log or in UI-specific transports. It does not provide session load/list/delete, commands, modes, configuration selectors, model switching, plan review, or human elicitation.
+
+One-shot `session/request_permission` remains. It is a machine policy channel for bridge-owned agents, not a human approval UI: the answerer accepts only an exact agent object in the bridge's live session map, delegates foreign or call-less requests, and maps failed RPCs to the fail-closed unavailable outcome. The client chooses allow once, reject once, or cancel, and the bridge never turns that response into a durable grant. Asking policy stays in the approval seam and its producers; [`dsh-subagent-acp`](../../../../packages/subagent/subagent-acp/README.md) uses this channel programmatically.
+
+The app composition contains the agent spine, persistence, checkpoint policy, and ACP transport. It does not mount command, session-query, session-reference, plan-mode, permission-picker, or user-interaction services for ACP. SDK scaffolding likewise treats `ask_user_question` as TUI-only.
+
+The transport programs interface-level agent, session, and approval services rather than the concrete agent loop. Tool execution stays inside the harness; ACP never delegates shell execution to an editor. stdout carries framed JSON-RPC only, so the app mounts no stdout logger and the bridge does not monkey-patch process output.
+
+Disconnect and plugin disposal share one memoized quiescence boundary. Both successful and failed transport closure settle pending prompts as cancelled, dispose every bridge-owned agent, and await loop and session cleanup. A create that loses the close race disposes its unpublished handle.
+
+## Snapshot boundary
+
+The ACP snapshot suite still boots the assembled ACP example and retains scenarios that pin backend behavior. Only scenarios driven through deleted UI methods leave the suite; semantic-checkpoint recovery runs through the headless `stream-json` example because ACP no longer loads sessions.
+
+Protocol and lifecycle tests pin stop-reason and prompt codecs, version negotiation, fresh-session creation, text and resource-link flattening, rejection of empty or unsupported prompts, exact-agent permission ownership, multi-session isolation, prompt settlement, per-session cancellation, failed transport closure, ACP-only reload cleanup, and teardown quiescence. Built and real-stdio smokes reject stray stdout. The `session/new` branch that loses a real stdio close race remains coverage-exempt because the in-memory transport cannot reproduce that ordering; it disposes the unpublished handle, while the surrounding disposal tests pin the no-orphan invariant.
+
+## Alternatives considered
+
+**Keep ACP as an editor UI until Web reaches parity.** Rejected because it leaves two interactive contracts to evolve and keeps editor conventions in the automation boundary.
+
+**Keep the earlier editor bridge behind disciplined seams.** Rejected even though that bridge correctly used interface services, tool-owned render intents, approval and user-interaction answerers, harness-owned execution, and a stdout-pure composition. Its terminal cards were capability-gated, display-only Zed `_meta` projections with a text fallback rather than ACP `terminal/create`, so shell execution never left the harness. The projection derived each display terminal id from the stable per-call id to prevent collisions and recovered exit code or signal from the rendered status markers because the pure result presenter received content blocks rather than a structured exit; marker round-trip tests and an explicit no-capability `console` fallback test pinned both contracts. Those boundaries were coherent but could not make editor cards, session navigation, configuration pickers, and human elicitation belong in an automation protocol.
+
+**Replace ACP with a private subagent RPC.** Rejected because ACP already supplies a typed, interoperable process protocol and is used by the out-of-process subagent backend.
+
+**Remove machine permission requests with the other interaction features.** Rejected because an automated parent must answer a child agent's one-shot policy decision; this is control flow between agents, not presentation.
+
+**Delete the ACP snapshot suite or migrate every scenario in this change.** Rejected because most scenarios test the backend and remain valuable, while a full harness migration is an independent testing change. Only scenarios whose driver was a deleted UI method leave this suite.
+
+## Consequences
+
+ACP has a narrow contract suitable for agents and automation, while TUI and Web own human interaction and presentation. The package has fewer injected services, dependencies, protocol branches, and lifecycle states, and it no longer claims compatibility as a general editor front door.
+
+Automation clients receive complete committed text rather than token deltas or structured tool UI. They inspect durable logs or another API when they need reasoning, tool traces, titles, or richer state. Fresh-session-only operation also means callers that need durable browsing or resume use a host API rather than ACP.
+
+Backend snapshot coverage therefore remains transport-coupled to ACP even though that transport is incidental to the behavior under test.

+# Agent Note：ACP 作为仅面向自动化的协议
+
+Status: implemented
+
+[English](2026-07-23-acp-automation-only-protocol.md) | 中文
+
+## 问题
+
+ACP（Agent Client Protocol）桥接层已经变成第二套交互式产品 UI。它将持久事件转换为编辑器卡片、终端元数据、diff、计划、标题、推理、命令、模式、模型和权限选择器、会话导航以及面向人类的询问。这些职责与 TUI 和 Web 客户端重复，同时将自动化传输层与 UI 服务、持久化查询、展示策略和编辑器特定约定耦合在一起。
+
+ACP 仍有一个有用的职责：另一个 agent（智能体）或自动化控制器可以启动 harness 进程、创建隔离会话、发送文本、接收已提交的回答、取消工作并回答权限请求。跨进程 ACP subagent 后端依赖这个标准协议边界。
+
+快照套件使移除工作更复杂。大多数 ACP 场景测试的是组装后的 agent 后端，而不是 ACP 展示层；如果随编辑器桥接层一起删除整个套件，就会丢失大量无密钥行为覆盖。
+
+## 决策
+
+`@deepseek-ai/dsh-acp` 是位于 [`packages/acp/acp`](../../../../packages/acp/acp/README.md) 下、独立于 `ui` 包组的自动化传输层。其公开协议特意保持精简：版本协商、全新文本会话（每个会话最多允许一个进行中的提示词）、已提交的助手文本更新、按会话取消、并发会话，以及由连接负责的资源清理。提示词只承载规范要求的基线内容——文本，加上被展平为方括号文本引用的资源链接；桥接层会拒绝附加目录、MCP 服务器、超出基线的提示词内容（图片、音频、内嵌资源）、空提示词、未知会话和重叠提示词。
+
+桥接层只发出已提交的 `assistant/message` 文本。推理、原始分片、工具活动、待办事项、计划、标题、重试标记、终端元数据、diff、位置和资源链接仍保留在持久会话日志或 UI 专用传输层中。它不提供会话加载、列出与删除、命令、模式、配置选择器、模型切换、plan 评审或面向人类的询问。
+
+保留一次性 `session/request_permission`。它是为桥接层拥有的 agent 提供的机器策略通道，而不是面向人类的审批 UI：应答者只接受桥接层当前会话映射中的精确 agent 对象；外部请求或缺少调用标识的请求会继续委派；RPC 失败则映射为失败关闭的 `unavailable` 结果。客户端可选择允许一次、拒绝一次或取消，桥接层绝不会将该响应转换为持久授权。询问策略仍归审批 seam 及其生产者所有；[`dsh-subagent-acp`](../../../../packages/subagent/subagent-acp/README.md) 会以程序化方式使用该通道。
+
+应用组装包含 agent 主干、持久化、检查点策略和 ACP 传输层。它不会为 ACP 挂载命令、会话查询、会话引用、plan mode、权限选择器或用户交互服务。SDK 脚手架同样将 `ask_user_question` 视为 TUI 专属功能。
+
+传输层调用 agent、会话和审批的接口服务，而不依赖具体的 agent loop。工具执行仍留在 harness 内；ACP 绝不会把 shell 执行委派给编辑器。stdout 只承载分帧 JSON-RPC，因此 app 不挂载 stdout logger，桥接层也不会 monkey-patch 进程输出。
+
+断开连接与插件 dispose（资源释放）共享同一个经记忆化处理的静止边界。传输关闭无论成功还是失败，都会将待处理提示词以已取消状态结算，dispose 每个由桥接层拥有的 agent，并等待循环和会话清理完成。创建流程如果在与关闭的竞态中落败，就会 dispose 其尚未发布的 handle。
+
+## 快照边界
+
+ACP 快照套件仍会启动组装后的 ACP 示例，并保留用于锁定后端行为的场景。从该套件移出的只有通过已删除的 UI 方法驱动的场景；由于 ACP 不再加载会话，语义检查点恢复通过 headless `stream-json` 示例执行。
+
+协议与生命周期测试会锁定停止原因编解码器和提示词编解码器、版本协商、新会话创建、文本与资源链接展平、拒绝空提示词或不受支持的提示词、精确 agent 权限归属、多会话隔离、提示词结算、按会话取消、传输关闭失败、ACP 专属重载清理，以及拆卸完全停稳。构建产物冒烟测试与真实 stdio 冒烟测试会拒绝混入 stdout 的额外输出。`session/new` 中在真实 stdio 关闭竞态中落败的分支仍属于覆盖豁免，因为内存传输层无法复现这一顺序；该分支会 dispose 尚未发布的 handle，而周边 dispose 测试会锁定无遗留资源不变式。
+
+## 考虑过的替代方案
+
+**在 Web 达到同等能力前，继续将 ACP 作为编辑器 UI。** 不予采用，因为这会留下两套需要演进的交互契约，并使编辑器约定继续存在于自动化边界中。
+
+**通过严格的 seam 保留早期编辑器桥接层。** 不予采用，尽管该桥接层正确使用了接口服务、工具自有的 render intent、审批与用户交互应答者、harness 自有执行，以及保持 stdout 纯净的组装。其终端卡片是经过能力门控、仅用于展示的 Zed `_meta` 投影，并提供文本回退，而非使用 ACP `terminal/create`，因此 shell 执行从未离开 harness。该投影从稳定的逐调用 id 派生每个展示用终端 id，以避免冲突；由于纯结果展示器接收的是内容块，而不是结构化退出信息，它会从渲染后的状态标记中恢复退出码或信号。标记往返测试和显式的无能力 `console` 回退测试锁定了这两项契约。这些边界保持一致，却无法让编辑器卡片、会话导航、配置选择器和面向人类的询问成为自动化协议应有的职责。
+
+**用私有 subagent RPC 替换 ACP。** 不予采用，因为 ACP 已经提供类型化、可互操作的进程协议，并由跨进程 subagent 后端使用。
+
+**随其他交互功能一起移除机器权限请求。** 不予采用，因为自动化父 agent 必须回答子 agent 的一次性策略决策；这是 agent 之间的控制流，而不是展示层。
+
+**删除 ACP 快照套件，或在本次变更中迁移每个场景。** 不予采用，因为大多数场景测试后端且仍有价值，而完整的 harness 迁移是一项独立的测试变更。只有驱动脚本依赖已删除 UI 方法的场景才离开该套件。
+
+## 结果
+
+ACP 具有适合 agent 与自动化的精简契约，而 TUI 和 Web 拥有面向人类的交互与展示。该包注入的服务、依赖、协议分支和生命周期状态更少，也不再将自身定位为通用编辑器入口。
+
+自动化客户端收到完整的已提交文本，而不是 token 增量或结构化工具 UI。当它们需要推理、工具跟踪信息、标题或更丰富的状态时，需要查看持久日志或其他 API。只支持全新会话也意味着，需要浏览持久会话或恢复会话的调用方必须使用 host API，而不是 ACP。
+
+因此，后端快照覆盖仍与 ACP 传输层耦合，尽管对于受测行为而言，该传输层只是附带因素。

+# Agent Note: 对协议形态代码进行基于属性的测试
+
+Status: implemented
+
+[English](2026-06-11-property-based-testing.md) | 中文
+
+> 将原始提案与同一主题的决策记录合并为一篇。首次运行即发现了 BlockAssembler 重复 `block-end` 的真实 bug。
+
+## 问题
+
+基于示例的测试只能固定我们想到的用例。harness 的核心是协议形态的代码：分片流、事件日志、schema 转换、收件箱调度。这些场景的输入空间是组合式的，有趣的 bug 藏在没人写过示例的交错序列中。佐证：一个块组装的排序 bug 曾在 happy path 100% 行覆盖率下存活。逐文件 100% 覆盖率证明每一行都跑过了，但不能证明每种交错都是正确的。
+
+## 决策
+
+引入 `fast-check`（作为根 devDependency），在每个协议形态的包（package）中编写一个 `tests/properties.spec.ts`。生成器调优为*逼真但对抗性*的输入（而非均匀噪声），`numRuns` 控制在本地套件总耗时远低于约 10 秒。失败时打印可复现的 seed。（原始提案还草拟了一个夜间 CI job，以 100 倍迭代运行；该部分未交付。属性测试套件仅在常规的 `push`/`pull_request` CI 中运行，定时高迭代 job 仍属可能的后续工作。）
+
+- **dsh-llm / BlockAssembler：** 任意分片流（合法 + 畸形：重复索引、滞后分片、缺少 block-start）。不变式：`blocks()` 计数 ≤ 已见到的不同索引数；重组幂等（`blocks()` 在重复调用间稳定，且 `message().content` 与之一致）；`blocks()` 从不抛异常且仅产出合法的 content-block 标签；`finish` 反映最后一个 `finish` 分片，无此类分片时默认为 `{kind:'stop'}`。
+- **dsh-session：** 任意事件日志。不变式：`deriveMessages` 确定性；从 seed 回放结果一致；seq 严格单调递增；非消息事件不影响推导出的历史；推导出的内容与日志解耦。
+- **dsh-tools：** 任意 `ParameterSchemaSpec`。不变式：JSON Schema 的 `required` 等于每一层 `required:true` 的键集；转换对合法声明而言是全函数；**并且与[运行时参数校验](../architecture/2026-06-11-runtime-arg-validation.md)组合验证**——满足 spec 的生成参数通过 `validateArgs`，而定向破坏（删除必填键、顶层非对象）被拒绝。聚焦用例覆盖每种根值类型、恰好一项匹配中的分支重叠与无匹配、显式开放性、原始默认值以及有损 JSON。这封堵了编译器、validator 与 `InferArgs` 之间的漂移风险。
+- **dsh-agent-loop：** 任意发送调度，对接一个永不耗尽的适配器，通过 `agent/status` settle 信号驱动（无挂钟 sleep）。不变式：无消息丢失；轮次编号严格递增；状态转换保持在合法状态机上。
+
+## 后果
+
+- 生成器质量是价值杠杆——生成器偏向小索引池和短字符串，使碰撞与交错频繁发生。
+- **它已经带来回报：** BlockAssembler 流发现了一个真实 bug——同一索引处重复的 `block-end` 会改写已经完成的块。现已修复（首次关闭优先，与现有迟到项规则一致），并加入专用回归测试。
+- 属性测试因超时而 flake 是一个发现，不应通过重试消除。循环属性测试在设计上是确定性的（通过 `agent/status` settle），因此挂起即为真实缺陷。
+- 属性测试是对示例测试的补充而非替代；示例测试固定特定分支，服务于 100% 覆盖率门禁。

+快照测试会启动真实 ACP 示例，通过确定性脚本驱动其 stdio 协议，并将规范化输出与已提交的预期输出比较。从真实 API 一次记录的会话日志为后续所有模型流提供数据。fixture 就是产品普通的持久化 JSONL。
+
+### fixture 即持久化的会话 JSONL
+
+每个场景的 `session.jsonl` 都从真实运行中采集。`assistant/chunk` 事件复现模型流；工具、消息和边界事件捕获 harness 行为。因此，一份普通会话产物同时充当重放来源和行为预期输出。
+
+当场景固定另一种物理存储布局时，其 fixture 会从真实的未打包对应项机械派生。场景测试要求包含每一种预期存储行类型，并在解码后逐事件精确相等；随后，普通重放与日志比较才会证明组合后的进程能够消费并复现该布局。
+
+### 回放从日志推导模型脚本
+
+`llm-replay` 短路了提供方无关的 `llm/stream` waterfall（瀑布式事件）。`deriveReplayScript()` 按 `(turn, step)` 对已录制的分片分组，每次模型调用服务一组。agent loop（智能体循环）每个步骤发起一次流调用，因此分组精确对应，错误结束分片也无需特殊处理。
+
+### 内存中的回放条目遵守完整的 LLM 契约
+
+`deriveReplayScript` 产出一组 `ReplayEntry`，即回放监听器按位置服务的内存单元：
+
+```
+{ kind: 'chunks', chunks: StreamChunk[] }
+| { kind: 'throw', chunks: StreamChunk[], message: string, code: string }
+| { kind: 'hang' }
+```
+
+日志推导出分片条目。流开始前的抛出和挂起没有可重建的分片表示，因此这些场景提供 `replay.override.json`。throw 条目可以包含前缀分片以模拟流中途失败。显式覆盖避免了从有损的轮次结束原因推断适配器行为。
+
+### 位置式回放，单个在途流
+
+回放是位置式的，因此每个场景只允许一个在途模型流。并发会话快照需要按请求键索引的条目。调用顺序变更需要重新录制，fixture 缺失或耗尽时立即报错。
+
+### 录制采集日志；无密钥回放需要无提供方的配置
+
+记录模式使用真实 `llm-deepseek` 适配器和配置为 `persistenceCompression: 'none'` 的 JSONL 持久化后端运行场景，再把生成的 `.jsonl` 复制到场景目录。显式 raw 模式让已提交重放 fixture 保持逐行可读，而普通部署使用后端的压缩默认值。逐事件追加具有持久性，但 harness 会在采集前优雅关闭子进程（关闭 stdin → `await ctx.dispose()`），以确保最终事件已刷出。`llm-replay` 本身不执行记录——它只负责重放。
+
+重放使用 `cordis.snapshot.yml` overlay，以 `llm-replay` 替换真实适配器，同时保留实时组合。记录使用普通配置和由 harness 提供的持久化根目录。重放模式跳过 `.env` 加载，因此意外存在的 API 密钥不会触发实时调用。参见[单一来源配置 Agent Note](2026-07-04-single-source-acp-replay-config.md)。
+
+### 两个表面：归一化后比对
+
+快照运行断言**两个**归一化后的表面，因为 harness 的外部表面是不同的：
+
+1. **stdout transcript**——自动化客户端收到的、经过 framing 的 ACP JSON-RPC 响应与已提交的消息更新。它捕获传输契约的回归，与已提交的 `stdout.expected.jsonl` 比较。
+2. **重新持久化的会话 JSONL**，经过规范化后与 `session.jsonl` 比较。同一 fixture 同时作为重放来源和预期日志。提示词文本会被清理；按照[请求头固定 Agent Note](2026-07-06-pin-request-header-content-in-one-scenario.md)所述，每种请求头类别由一个场景固定可读提示词与工具内容。Override 场景仅从其 sidecar 派生模型行为。
+
+两个表面互补：stdout 覆盖精简的自动化线协议，JSONL 覆盖线协议有意省略的 loop、工具和 boundary 结构。
+
+规范化会替换会话、cwd、协议 id、时间戳、路径和进程易变值，同时保留确定性序号。场景把真实 bash 使用限制在稳定命令上。stdout 预期输出仍是线协议形状的 JSONL，每个原始行都必须可解析为 JSON。Vitest 只更新 stdout 预期输出；规范化会话相等性检查从不覆盖重放 fixture。
+
+### 隔离：当前靠归一化，后续可加沙箱
+
+工具确定性来自生成的 cwd、清理后的环境、全新的非登录 shell、受限命令和规范化。cwd 默认为平台临时目录；当临时目录是始终可写的策略根，而行为需要独立项目位置时，场景可以改为提供其父目录。并发重放运行各自拥有独立 cwd、持久化目录和由定长场景键区分的 spill 根目录，因此一个场景的拆除无法删除另一个场景仍在进行的完整输出恢复，同时真实路径预览预算保持稳定。该层不声称提供 OS 级隔离。如果需要更强层级，沙箱执行器可以通过现有[能力 seam](../architecture/2026-06-13-capability-seams.md)替换本地后端。
+
+### 回放插件是独立的包
+
+`@deepseek-ai/dsh-llm-replay` 是一个支撑包（package），而非示例本地的胶水代码。它通过用从 JSONL 重建的流短路 `llm/stream` 来替换真实适配器，其包级放置使回放逻辑处于正常覆盖率门禁之下。
+
+### 两个子命令，回放在默认门禁中
+
+`pnpm run test:snapshot` 无需密钥即可重放已提交 fixture；`test:snapshot:record` 使用真实 API，并重写采集的会话日志与 stdout 预期输出。缺少 fixture 时会响亮失败。每个场景都包含 `input.json`、`stdout.expected.jsonl` 和 `session.jsonl`；不调用模型的情况使用仅有请求头的日志。只有标记为 `overridden` 的场景才需要 `replay.override.json`，因为它一旦存在就会取代派生重放。Fixture 守卫会拒绝缺失、不匹配和孤立文件。两个命令都接受场景过滤器。
+
+## 曾考虑的替代方案
+
+- **手工编写包含模型分片的 `llm.json`**——早期草案；复用真实会话日志，使 fixture 成为系统的真实产物而非手工构建的 mock，并让它同时充当行为预期输出。
+- **字节级 HTTP 录制库（Polly/nock/MSW）**：否决。与适配器耦合，处理流式 SSE（Server-Sent Events）时笨拙，且层级低于被测对象。
+- **从 `turn/end {kind:'error'|'aborted'}` 合成抛错/取消条目**：否决。这会将 `llm-replay` 耦合到 loop 内部的轮次关闭语义，且 `turn/end` 原因是有损的（无法区分抛出的 401 与 finish-error）；显式的 `replay.override.json` 伴随文件是更清晰的 seam。
+
+## 后果
+
+该测试层为每个场景增加经过评审的输入、会话、stdout、可选 override 和可选 workspace fixture。记录与重放都会把 workspace seed 复制到生成的 cwd。作为回报，该层通过真实 Loader 和工具组合提供确定性的无密钥覆盖。保留下来的大多数场景测试的是组装后的后端而非 ACP；[仅面向自动化的 ACP 决策](../simplification/2026-07-23-acp-automation-only-protocol.md#snapshot-boundary)将该语料保留在此处，并把向传输无关 headless 套件的任何迁移推迟为一项独立的测试变更（套件级 FIXME 标记了这一点）。
+
+本 Agent Note 与[拟议的确定性 Agent Note](../../proposed/testing/2026-06-11-deterministic-and-stress-testing.md)相关，但不取代它：该提案的“通用重放 fixture”在每次测试后重新派生会话*消息历史*（内部一致性不变量），而这些快照固定组装后的行为与外部自动化输出。在后端语料迁出 ACP 之前，两者相互补充。

## Problem
-The harness leans hard on real-API tests by policy: [docs/testing.md](../../../../docs/testing.md) argues that a no-key suite proves the plumbing but not the product, and the [ACP inject postmortem](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md) is the standing proof — 178 keyless tests stayed green while a real editor session crashed instantly. The real-API e2e suite (`pnpm run test:e2e`, the `*.e2e.ts` files) exists precisely to close that gap: it drives the agent against the live DeepSeek API — real model calls, real bash tools, multi-turn, resume, ACP-over-stdio.

The default gate ([.github/workflows/ci.yml](../../../../.github/workflows/ci.yml)) is deliberately keyless: it carries no secret and runs for forks. `test:e2e` self-skips without a key (`describe.skipIf(!process.env.DEEPSEEK_API_KEY)`), so adding it there would report green without exercising the real suite. A separate secret-bearing workflow is required to make real-API coverage a merge signal.

+# Agent Note: 在 CI 中对外部 DeepSeek API 运行真实 API e2e 测试
+
+Status: implemented
+
+[English](2026-06-19-real-api-e2e-ci.md) | 中文
+
+## 问题
+
+根据策略，harness 高度依赖真实 API 测试：[docs/testing.md](../../../../docs/testing.md) 指出，无密钥套件证明的是管线，而非产品；[ACP（Agent Client Protocol）inject 事后分析](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md)则是常设证据——178 项无密钥测试保持绿色时，真实 ACP 客户端会话却立即崩溃。真实 API e2e 套件（`pnpm run test:e2e`，即 `*.e2e.ts` 文件）的存在正是为了弥合这一缺口：它针对实时 DeepSeek API 驱动 agent（智能体）——真实模型调用、真实 bash 工具、多轮次、恢复、ACP-over-stdio。
+
+默认门禁（[.github/workflows/ci.yml](../../../../.github/workflows/ci.yml)）刻意无密钥：不携带 secret，可供 fork 运行。`test:e2e` 在无密钥时自动跳过（`describe.skipIf(!process.env.DEEPSEEK_API_KEY)`），因此将其加入该工作流只会报绿而不会真正执行真实套件。要让真实 API 覆盖率成为合并信号，需要一个独立的、携带 secret 的工作流。
+
+本 Agent Note（agent 决策记录）记下了新增**第二条消费 secret 的工作流**以在 CI 中运行真实 API 套件的决策；由于向未来可能公开的仓库引入第一个 CI secret 属于安全/隔离决策，本文也记录其依赖的威胁模型，以及仓库公开时需要做出的变更。
+
+## 决策
+
+添加一个专用工作流 [.github/workflows/e2e.yml](../../../../.github/workflows/e2e.yml)，与 ci.yml 分离。它仅使用 repo secret 对外部 API 运行 `pnpm run test:e2e`，仅在可信事件上触发，并带有一个 preflight 检查：将缺失的 secret 转化为明确的失败而非虚假的绿色。无密钥工作流保持独立，使可 fork 的质量门禁与消费 secret 的真实 API 门禁各自拥有不同的触发和凭证策略。
+
+### 独立工作流，而非 ci.yml 中的一个 job
+
+ci.yml 的价值在于它无密钥、可 fork、始终为绿：任何贡献者（包括外部 fork）都能获得完整的无密钥信号，secret 不在爆炸半径内。在其中添加消费 secret 的 job 会将这个始终为绿的门禁耦合到凭证可用性和不同的触发策略上。将携带 secret 的工作放在独立文件中，隔离了 secret、触发和并发策略，并为 fork 保留了 ci.yml 的特性。不同的生命周期→不同的文件。
+
+### 约束不是成本，而是可靠性
+
+内部推理成本不是限制因素，因此工作流针对覆盖面和信号优化。它会在多种触发条件和每个受信任 PR（Pull Request）上运行所有匹配的 `*.e2e.ts` 文件，以落实 [docs/testing.md](../../../../docs/testing.md) 的有密钥策略。
+
+### 触发条件：仅限可信事件
+
+`workflow_dispatch` + `push` 到 `main`/`master` + 每夜 `schedule`（`17 0 * * *`，即北京时间 08:17）+ `pull_request`。push 提供合并后信号；schedule 捕捉外部 API 漂移；dispatch 是手动逃生通道；可信 pull request 获得合并前门禁。该合并前信号有意接受 § 安全性中描述的更大密钥暴露面。
+
+### 不可信 PR 的门禁
+
+GitHub 对两类 PR 扣留 repo secret：来自 **fork** 的 PR，以及 **Dependabot** PR（同仓库分支，`head.repo.fork == false`，但 secret 仍被扣留）。一个 job 级 `if:` 对两者都跳过整个 job：
+
+```
+github.event_name != 'pull_request'
+ || !(github.event.pull_request.head.repo.fork || github.event.pull_request.user.login == 'dependabot[bot]')
+```
+
+Dependabot 子句基于 PR **作者**（`pull_request.user.login`）而非 `github.actor`（运行触发者）：维护者重新打开或重跑 Dependabot PR 时，`github.actor` 会变成人类，但该 PR 仍然无密钥；基于作者的判断在这种情况下依然正确。被 **job 级** `if:` 跳过的 job 报告为*成功*检查（不同于工作流/触发级跳过会保持 pending），因此如果需要将此工作流标记为 required status check 也是安全的——fork/Dependabot PR 的跳过但绿色的检查不会阻塞合并。
+
+该门禁是一个*干净跳过的便利措施*，而非 secret 的安全边界（见 § 安全性——边界是 GitHub 自身在 `pull_request` 下对 fork 的 secret 扣留机制）。没有该门禁，fork 仍然无法读取密钥；只是会遇到令人困惑的 preflight 硬失败并浪费计算资源。
+
+### Preflight：大声失败，绝不虚假为绿
+
+由于 job 仅在 secret 应当存在的可信事件上运行，preflight 是一个无条件的存在性检查：密钥为空→`exit 1` 并附带 `::error::` 注解指明需要配置的 secret 名称。这是让自跳过套件可以安全地作为门禁的关键。没有它，被删除/重命名/错误配置的 secret 会让 `test:e2e` 跳过所有真实套件并报告全绿——整个安全网的静默退化。该守卫将「secret 缺失」从不可见的虚假通过转化为可见的失败。（其正确性已在实际中验证：secret 存在之前的运行恰好在此步骤失败。）
+
+### Secret 映射与卫生
+
+repo secret 命名为 `DEEPSEEK_API_KEY_EXTERNAL`；映射到适配器和测试读取的 `DEEPSEEK_API_KEY` 环境变量（`process.env.DEEPSEEK_API_KEY`）。独立的 secret 名称记录了意图（这是*外部*公开 API 密钥，不是内部端点密钥），并允许内部端点密钥日后无冲突地共存。以下卫生选择均为防御性设计：
+
+- **步骤级 secret。** `DEEPSEEK_API_KEY` 仅在 preflight 和 e2e 步骤的 `env:` 中设置，从不在 job 级设置——因此 checkout/setup-node/install 永远看不到它。依赖中被入侵的安装时生命周期脚本无法读取不在其环境中的 secret。
+- **`permissions: contents: read`。** job 仅读取仓库以运行测试；不需要写权限（无 PR 评论、无 status 写入），因此 `GITHUB_TOKEN` 降至最小权限。
+- **`DEEPSEEK_BASE_URL` 固定**为 e2e 步骤上的 `https://api.deepseek.com`。适配器在未设置时会默认使用此值（[packages/llm/llm-deepseek/src/index.ts](../../../../packages/llm/llm-deepseek/src/index.ts) `PUBLIC_BASE_URL`），但显式固定具有自文档性和密封性——仓库根目录的 `.env`（`vitest.e2e.config.ts` 存在时会加载）无法静默地将运行重定向到其他端点。
+- **不回显 secret。** preflight 仅打印 `DEEPSEEK_API_KEY present.`——不打印值或长度。
+
+### 范围与运行时形态
+
+job 仅在 Node 24 上运行 `test:e2e`；无密钥门禁和版本兼容性属于主 CI 工作流。测试通过 workspace paths 映射以未构建形式运行，使用有界的可配置 worker 池、逐测试重试和 job 超时。被取代的 PR 运行会被取消，而 push 和 schedule 运行完整执行以提供合并后信号。
+
+DeepSeek 原生 `web_search` 探测已注册但会跳过。实时 Anthropic 兼容端点可能返回成功响应却没有结构化来源块，因此对来源存在性的正向断言不是可靠的合并信号；单元覆盖率仍会固定响应解析，但 CI 不会证明实时来源块的线协议形状。
+
+## 安全性
+
+仓库的首个 CI secret 需要一份记录在案的威胁模型，因为同仓库 PR、fork PR 和 Dependabot PR 的访问权限各不相同，且仓库公开后会发生变化。
+
+### 当前谁能触及 secret（私有仓库）
+
+- **无写权限（fork PR）：不能。** 两个独立事实阻止了它。第一，工作流使用 `pull_request` 而**非** `pull_request_target`——GitHub 不会将 repo secret 传递给 fork PR 的 `pull_request` 运行，因此 `secrets.DEEPSEEK_API_KEY_EXTERNAL` 在 fork runner 上解析为空。第二，`if:` 门禁完全跳过 fork PR。secret 扣留是真正的边界；门禁是纵深防御和用户体验。
+- **有写（push）权限：能。** 同仓库分支 PR 会收到 secret，因此有写权限的作者可以修改测试代码（或安装生命周期脚本，或其分支上的工作流 YAML）来窃取密钥。这**是 GitHub Actions 的固有特性，并非本文引入的**：任何对任何仓库有 push 权限的人都可以通过编写工作流来窃取该仓库的任何 Actions secret。写权限⇒secret 访问权，始终如此。缓解措施在于谁被授予写权限以及分支保护，而非本文件。
+
+因此「任何能开 PR 的人都能窃取它」是错误的：只有写权限集合内的人能，而这些人本来就能窃取仓库持有的任何 secret。
+
+### `pull_request` 触发器增加的残余暴露面
+
+由于启用了 PR 运行，密钥会在合并前被交给**写权限作者 PR 分支上的代码**。这比 `push` + `schedule` + `workflow_dispatch` 的暴露面更大，为在可信写权限集合内获得合并前信号而接受。如果这一权衡发生变化，可移除 `pull_request` 触发器，同时保留合并后、每夜和按需覆盖。
+
+### 仓库公开后的变化
+
+**通过本工作流**，secret 对公众仍然受保护：`pull_request` 在公开仓库上行为一致——fork PR（现在任何人都能开）仍然收不到 secret，且在公开仓库上 GitHub 额外要求维护者批准 fork PR 运行，即使批准后运行也不会获得 secret（批准运行不等于交出密钥）。写权限集合不因可见性改变而改变，因此内部人员的现实也不变。
+
+变差的是*周边*模型，以下是翻转可见性之前需要处理的事项：
+
+- **日志变为全球可读。** 今天泄露给组织成员的粗心 secret 回显，公开后会泄露给整个互联网并在数分钟内被爬取。secret 处理纪律（不回显值/长度——已做到）的重要性大幅提升。
+- **`pull_request_target` 陷阱变为灾难性的。** 如果有人为了「修复」PR 运行而将触发器切换为 `pull_request_target`，工作流将在 base-repo 上下文中运行不可信的 fork 代码并**携带** secret——完整的密钥泄露向量。在私有仓库中这勉强无害，在公开仓库中则是灾难。e2e.yml 中触发器上的 `SECURITY —` 注释禁止此更改并指向本文。
+- **翻转时轮换密钥。** 密钥曾存在于私有仓库的 CI 中；将公开视为「假定已暴露」，在那一刻轮换 `DEEPSEEK_API_KEY_EXTERNAL`。
+- **将 secret 置于控制之下。** 确认 Settings → Actions → *"Send secrets to workflows from fork pull requests"* 保持**关闭**（这是唯一真正会打破 fork 边界的设置），并考虑将密钥移入带有 required reviewers 的 GitHub **Environment**，使即使已合并的代码也只在受控条件下使用它，且轮换有单一归属。
+
+以上均不需要修改工作流即可公开；它们是运维步骤加上已添加的 `pull_request_target` 守卫注释。
+
+## 曾考虑的替代方案
+
+- **在 ci.yml 中添加消费 secret 的 job**：否决。会将无密钥、可 fork、始终为绿的门禁耦合到凭证可用性和不同的触发/并发策略上；不同的生命周期，不同的文件。
+- **省略 `pull_request` 触发器**（更小的密钥暴露面）：为获得合并前信号而否决；安全性章节承载了已接受的暴露分析。
+
+## 后果
+
+新增一个 CI 工作流和仓库的首个需要维护的 secret。真实 API 套件现在作为合并门禁（可信 PR 上的合并前门禁、主分支上的合并后门禁）并每夜运行，因此 agent 与外部 API 交互中的真实故障会在 CI 中浮现，而非仅在开发者的本地运行中出现——代价是每个可信 PR 和合并都会产生真实的（但内部免费的）API 调用。preflight 使 secret 配置错误变为自我通告而非静默禁用安全网。
+
+该设计带有已记录的约束表面：`pull_request` 触发器在密钥暴露方面的取舍（删除它可加强防护）、`if:` 门禁对基于作者的 Dependabot 检查的依赖，以及对 `pull_request_target` 的严格禁止。上方公开仓库检查清单是操作配套——未来维护者在更改触发器集合或切换仓库可见性之前，应重新阅读本 Agent Note，而不是从头推导 fork/secret 模型。
+
+schedule 触发器在仓库不活跃 60 天后会自动禁用（GitHub 行为）；push/PR/dispatch 是后备，活跃的 monorepo 不会触及此限制。假设 runner 对 `https://api.deepseek.com` 有出站连通性——GitHub 托管的 `ubuntu-latest` 具备此条件；受出站限制的自托管 runner 需要在依赖每夜运行之前确认连通性。

## Problem
Model-driving ACP snapshot scenarios ship both `session.jsonl` and `session.expected.jsonl`. For normal recorded scenarios, `session.jsonl` is the replay fixture harvested from a real run, and the replay test normalizes the newly persisted log and compares it to `session.expected.jsonl`. In the current fixtures, the two normalized logs are identical for ordinary recorded scenarios.

+# Agent Note: 使用 `session.jsonl` 作为唯一的快照会话日志产物
+
+Status: implemented
+
+[English](2026-06-20-remove-redundant-snapshot-log-expected-output.md) | 中文
+
+## 问题
+
+驱动模型的 ACP（Agent Client Protocol）快照场景同时包含 `session.jsonl` 和 `session.expected.jsonl`。对于普通记录场景，`session.jsonl` 是从真实运行采集的重放 fixture（测试前置数据）；重放测试会规范化新持久化的日志，并将其与 `session.expected.jsonl` 比较。在当前 fixture 中，普通记录场景的两份规范化日志完全相同。
+
+手工编写的 override 场景（`error-finish`、`cancel`）目前使用 `replay.override.json` 驱动模型行为，并把 `session.jsonl` 保留为最小 dummy fixture，而 `session.expected.jsonl` 存放预期的持久化日志。override 文件是由 `ReplayEntry` 对象组成的 JSON 数组：`{ "kind": "chunks", "chunks": StreamChunk[] }`、`{ "kind": "throw", "chunks": StreamChunk[], "message": string, "code": string }` 或 `{ "kind": "hang" }`。这种拆分同样没有必要：override sidecar 存在时，`llm-replay` 会替换派生脚本，不需要从 `session.jsonl` 取得模型分片，因此 `session.jsonl` 仍可作为场景的预期会话日志产物。
+
+## 决策
+
+彻底移除 `session.expected.jsonl` 概念。每个场景最多只有一个已提交会话日志产物，即 `session.jsonl`：
+
+- 对于录制场景，`session.jsonl` 仍是原始采集的日志。回放仍从中派生模型分片，快照测试将回放运行归一化后的持久化日志与归一化后的 `session.jsonl` 进行比较。
+- 对于手工编写的覆盖场景，`replay.override.json` 驱动模型行为，`session.jsonl` 存放预期产出的会话日志。当覆盖文件存在时，回放适配器不从 fixture 获取模型分片，因此同一个文件既可作为预期日志，又不影响回放行为。
+- 对于无模型场景，`session.jsonl` 可保留为引导 `llm-replay` 所需的最小 fixture；除非场景创建了持久化会话，否则无需进行会话日志比较。
+
+Stdout 预期输出保持不变；它们是面向编辑器的投影，与会话 fixture 并不重复。
+
+## 曾考虑的替代方案
+
+**对两侧基于共享的（回放运行）上下文做归一化**：否决。`normalizeSessionLog` 通过精确字符串匹配擦除 cwd，因此 fixture 中录制的 cwd 不会被擦除，每次比较都会失败。两侧各自基于自身 header 派生的上下文做归一化——下方的实现说明描述了具体机制。
+
+## 验证
+
+快照 harness、fixture、孤立项守卫和文档中都不再出现 `session.expected.jsonl`；对于每个模型场景，快照测试都从 `session.jsonl` 派生预期会话日志；手工编写 sidecar 的场景把预期生成日志提交为 `session.jsonl`，并以 `replay.override.json` 覆盖模型行为；孤立 fixture 守卫知道每种场景类型所需的文件。[ACP 快照测试 Agent Note（agent 决策记录）](2026-06-19-acp-snapshot-tests.md)描述了精简后的 fixture 集合。
+
+## 后果
+
+评审者失去了一个能在视觉上区分预期持久化日志与重放 fixture 的产物名。stdout 预期输出仍然保护编辑器 transcript（文本记录），而将重放输出与 `session.jsonl` 比较，无需复制文件即可保留循环/持久化回归检查。
+
+## 实现说明
+
+两侧各自基于自身 header 值做归一化，因为录制与回放具有不同的 id、路径和时间戳。`fixtureContext()` 从 fixture 的 header 派生上下文，使已归一化的 fixture 具有幂等性。会话日志使用普通相等比较而非文件快照更新，因此比较过程不会改写 fixture。

## Problem
The [per-session snapshot replay Agent Note](2026-06-22-subagent-snapshot-replay.md) made the snapshot tier express a nested-agent shape: a parent plus one recorded log per in-process subagent, each replayed as its own script keyed by calling session. It noted (§ Scope, final bullet) that a fork snapshot was "a trivial future addition, not a gap in the keying." That was wrong about a fork child specifically — not the keying, but the *script derivation*.

+# Agent Note: 持久化 seed 边界以确保 fork 子会话回放正确路由

+
+## 问题
+
+[逐会话快照重放 Agent Note（agent 决策记录）](2026-06-22-subagent-snapshot-replay.md)使快照层能够表达嵌套 agent 形状：一个父项加上每个进程内 subagent 的一份记录日志，每份日志都按调用会话作为键，以独立脚本重放。它曾指出（§ 范围，最后一个项目符号），fork 快照“只是未来很容易添加的一项，并非键控缺口”。这一判断对 fork 子项而言是错误的——问题不在键控，而在*脚本派生*。
+
+subagent 脚本由 [`deriveReplayScript`](../../../../packages/support/llm-replay) 从已录制的会话日志推导：它按 `(turn, step)` 对日志中的 `assistant/chunk` 事件分组，每次 `stream()` 调用对应一条回放条目。对 **spawn** 子会话而言这是正确的，因为其日志只包含自身的模型调用。
+
+**fork** 子会话不同。fork 后端用*父日志的一段平衡的已完成轮次前缀*（[`dsh-subagent-inprocess`](../../../../packages/subagent/subagent-inprocess)）来播种子会话，而该 seed 会成为子会话持久化的 `log`（`Session` 构造函数将 seed 复制进 `this.log`）。因此 fork 子会话的 `.jsonl` 以**父会话**的事件开头——包括父会话的 `assistant/chunk` 事件——之后才是子会话自身的轮次。
+
+从 fork 子会话的完整日志推导脚本，会把**父会话**的已录制响应当作**子会话**的模型调用来回放：实际运行的 fork 子会话第一次调用 `stream()` 时，会收到父会话的第一段分片序列而非自身的。目前已录制的场景全部是 spawn，所以这从未触发——但 fork 快照会静默地错误路由，恰好属于快照层存在的意义所要捕获的那类 bug。
+
+## 决策
+
+记录会话**继承**前缀的结束位置，将其持久化，并让回放 harness 仅从子会话**自身**的事件推导脚本。
+
+### 1. 会话头部的 `seedLength`
+
+`SessionHeader` 新增可选字段 `seedLength: number`——表示有多少前导事件是通过 seed 继承而来、而非本会话产生的。fork 后端在创建子会话时设置它（= 播种前缀的长度）；全新的 spawn 子会话不设置（等同于 0）。它通过 `CreateSessionOptions.meta`（及 `CreateAgentOptions.meta`）传递，在 `SessionStore.prepare` 中设置。
+
+`seedLength` 是**显式**的，绝不从 `seed.length` 推断。恢复/加载时用会话的完整已存储日志作为 seed，此时 `seed.length` 是全长而非原始边界——恢复路径改为从加载的 header 中取回持久化的 `seedLength`。（形状与 `createdAt` 相同：恢复时显式保留，而非重新默认为当前时间。）
+
+### 2. 两个持久化后端均完整往返
+
+- **JSONL**：header 行上的 `seedLength` 字段（`toHeaderLine`/`fromHeaderLine`）。
+- **SQLite**：`sessions` 表上的 `seed_length` 列。
+
+包含 `seed_length`、`source_event_seqs` 和 `surface_op` 的 SQLite 布局为 schema version 4。更早的 version 3 布局存在歧义，因此在预发布策略下，所有非当前 `user_version` 均直接拒绝，不做迁移。
+
+### 3. 回放从边界之后推导子会话脚本
+
+`dsh-llm-replay` 的 `parseSessionHeader` 现在也读取 `seedLength`（缺失则为 0），`loadSessionScripts` 从 `parseSessionLog(text).slice(seedLength)` 推导子会话条目——即边界及之后的事件，也就是子会话自身的模型调用。对 spawn 子会话而言 `seedLength` 为 0，此操作是空操作，spawn 场景逐字节不变。
+
+这关闭了路由正确性的缺口，两个已录制的 fork 场景对其进行端到端验证——见[记录 fork 与混合 spawn+fork 快照场景](2026-06-22-fork-snapshot-scenarios.md)。
+
+## 曾考虑的替代方案
+
+- **在 `llm-replay` 中启发式推导边界**（播种前缀是连续的父事件，止于子会话第一条 `user/message` 之前的最后一个 `turn/end`）。否决：在测试 harness 中用脆弱的启发式重新推导一个生产者已经知道的事实。在源头（fork 后端）持久化边界，是「在包（package）seam 处显式优于隐式」这条规则跨越持久化边界的应用——子会话 fixture（测试前置数据）的读取者永远不需要重建继承在哪里结束。
+- **固定格式版本而不递增**（事件日志使用的 `SESSION_FORMAT_VERSION = 0`「不稳定」姿态）。对 SQLite *表*布局否决：`SCHEMA_VERSION` 是单调递增并拒绝旧版的旋钮（一组小的、值得区分的修订），与事件词汇表的 `version` 不同。新增列正是它所版本化的那种破坏性表变更，因此需要递增。
+
+## 后果
+
+- core 与两个后端新增一个持久化 header 字段；核心数据结构目录（`persistence.md`）在同一变更中更新（其 `SessionHeader` / `CreateSessionOptions` 的 `type-equiv` 块）。
+- 既有的 schema v2 SQLite 数据库在打开时被拒绝（预发布阶段无用户数据）。
+- spawn 回放不变（`seedLength` 为 0）。fork 回放现在将子会话路由到自身的脚本；由 `llm-replay` 测试中的一个回归用例覆盖（一个子会话 fixture，其播种前缀包含父会话的分片——推导出的子会话脚本必须排除它，不做 slice 时该用例为红）以及一个持久化往返测试（两个后端，通过共享的 coordinator 契约）。

## Problem
The [seed-boundary Agent Note](2026-06-22-fork-child-replay-seed-boundary.md) made fork-child replay route correctly: `dsh-llm-replay` derives a child's script from the events at or after its persisted `seedLength` boundary, so a fork child's inherited parent prefix is not replayed as the child's own model calls. But it shipped with **no recorded fork scenario** — the slice was exercised only by `llm-replay`'s unit tests (a synthetic child fixture) and a persistence round-trip test. The full-transcript snapshot tier, the one net that boots the real `acp-agent` and replays an end-to-end nested transcript, had only spawn children (`subagent-spawn`, `subagent-multi`). A fork-routing regression that left the unit tests green would still have escaped the tier built to catch transcript regressions.

+
+## 问题
+
+[seed 边界 Agent Note（agent 决策记录）](2026-06-22-fork-child-replay-seed-boundary.md)让 fork 子项重放能够正确路由：`dsh-llm-replay` 根据持久化 `seedLength` 边界处及其后的事件派生子项脚本，因此 fork 子项继承的父前缀不会作为子项自身的模型调用重放。但落地时**没有记录式 fork 场景**——slice 只由 `llm-replay` 单元测试（合成子项 fixture（测试前置数据））和持久化往返测试覆盖。完整 transcript（文本记录）快照层——会启动真实 `acp-agent` 并重放端到端嵌套 transcript 的那张网——只有 spawn 子项（`subagent-spawn`、`subagent-multi`）。如果 fork 路由回归没有让单元测试变红，它仍会逃过专为捕获 transcript 回归而构建的这一层。
+
+表达 fork 场景所需的快照基础设施已经就位：两个进程内后端都在 `cordis.yml` / `cordis.snapshot.yml` 中以两个面向模型的工具接入（`subagent` → spawn、`subagent_fork` → fork），harness 会收集每个子会话的日志，回放按 `seedLength` 为键转发各子会话的 fixture。缺少的是一个*已记录的场景*来驱动 fork 子会话走完这条路径。
+
+## 决策
+
+针对真实 API 记录两个场景，均在默认门禁中以无密钥方式回放：
+
+- **`subagent-fork`**：父会话完成一个轮次以建立一个事实，然后通过 `subagent_fork` 委派一个子任务。fork 子会话继承对话（其日志携带非零 `seedLength`），因此可以从父会话的上下文中作答。这是聚焦的回归守卫：子会话 fixture 的 `seedLength` 就是回放切片所依赖的边界，来自真实 fork 的记录而非手工合成。
+- **`subagent-mixed`**——父项完成一个轮次，随后在同一 transcript 中通过 `subagent` 委托一次（全新 spawn 子项，`seedLength` 为 0），再通过 `subagent_fork` 委托一次（fork 子项，`seedLength` 非零）。这是 seed 边界与逐会话重放 Agent Note 都点名作为未来新增项的 spawn+fork 混合场景：一份 transcript 覆盖两种传输方式和 slice 的两个分支（`seedLength` 为 0 = 无操作，`seedLength > 0` = 裁剪继承前缀），两个子项按 `createdAt` 排列为先 spawn、后 fork。
+
+### 为什么需要一个已完成的第一轮次
+
+fork 后端使用父项的**已配平完整轮次前缀**为子项提供 seed。父项若在第一个轮次就执行 fork，没有已完成轮次可供继承，因此 seed 为空（≡ 全新 spawn，`seedLength` 为 0）——这不会覆盖 slice。因此，两个场景都使用双提示词输入：第一个提示词完成一个轮次（建立稍后要求子项回忆的 codeword），第二个提示词委托 fork。子项 transcript 中回忆出的 codeword 只是模型行为的附带结果；承载关键约束的产物是子项 fixture 中记录、由重放 slice 消费的 `seedLength`。
+
+## 后果
+
+- fork 路由切片现在由全 transcript 层守卫，而不仅仅是单元测试。移除 `slice(seedLength)`（回放整个子会话日志）会让**两个**新场景变红——fork 子会话收到的是父会话记录的分片而非自己的——证明守卫确实生效（场景落地时已验证红→绿）。
+- `subagent-mixed` 是第一个在同一个 transcript 中驱动两种*不同* subagent 后端的快照场景，同时覆盖了跨 spawn 和 fork 子会话的逐会话回放键控。
+- 进程外（ACP（Agent Client Protocol））subagent 回放形态不同（每个子会话是独立进程、有自己的回放），仍以 `TODO(acp-subagent-replay)` 跟踪——本文场景仅限进程内。
+- 重新录制（`pnpm run test:snapshot:record`）会从真实 API 重新生成全部四个 fork/spawn fixture；两个新场景在无密钥时自动跳过，与所有已录制场景一致。

+# Agent Note: 嵌套 agent 的逐会话快照回放
+
+Status: implemented
+
+[English](2026-06-22-subagent-snapshot-replay.md) | 中文
+
+## 问题
+
+快照层（`pnpm run test:snapshot`）会启动真实 `acp-agent` 子进程，通过 [`dsh-llm-replay`](../../../../packages/support/llm-replay) 重放已记录会话，并将规范化后的自动化线协议 + 重新持久化的会话日志与已提交预期输出进行 diff。大多数场景通过这条真实进程边界测试组装后的后端行为。
+
+该层最初为每个进程只有一个会话而构建，这一假设硬编码在两处：
+
+- **`dsh-llm-replay` 没有做任何键控。** 它用一个全局游标，将第 N 次 `llm/stream` 调用对应到单一录制序列的第 N 条。当父 agent（智能体）和一个进程内 subagent 在同一个上下文上同时流式输出时，调用交错，单一游标会把子 agent 的脚本发给父 agent（反之亦然）。
+- **harness 只收集一份日志。** `findSessionLog` 遍历 sessions 根目录，返回找到的第一个 `.jsonl`。subagent 作为第二个 `Session` 运行并拥有自己的日志，因此子 agent 的 transcript（文本记录）被静默丢弃。
+
+这就是 [subagent seam Agent Note（agent 决策记录）](../feature/2026-06-21-subagent-capability-seam.md)中通过 `TODO(subagent-snapshots)` 推迟的工作：进程内后端（PR2）落地时已有单元 + e2e 覆盖，但在这套基础设施落地前，完整 transcript 快照层无法表达嵌套 agent 形状。本 Agent Note 就是该堆叠式后续工作。
+
+## 决策
+
+回放按**调用方会话**键控，harness 收集**所有**会话日志。
+
+### 1. 调用方会话 id 附着在模型请求上
+
+`GenerateOptions` 新增可选字段 `sessionId`，在请求组装时从 `agent.session.id` 赋值。适配器忽略它；`llm/stream` 监听器用它按发起会话路由。其类型为 `Branded<'SessionId'>`（来自 `dsh-brand`）而非 `dsh-session` 的 `SessionId`，因为后者所在包（package）导入了 `dsh-llm` 的 `Message`，反向导入会形成循环。两个类型等价，因此会话 id 赋值无需类型转换。将 brand 移到一个专用 ids 包属于独立工作，因为它会影响所有 id 导入。
+
+### 2. 回放按首次调用顺序将活跃会话绑定到录制脚本
+
+嵌套场景录制多份日志：父会话（`session.jsonl`）加每个 subagent 子会话各一份（`session.1.jsonl`……）。`dsh-llm-replay` 全部加载，为每个录制会话派生一份脚本，并按 header 中的 `createdAt` 排序（父会话先于子会话创建）。
+
+活跃会话 id 每次运行都是全新随机值，永远不等于录制时的 id，因此活跃会话无法通过 id 相等绑定到脚本。取而代之的是**首次调用顺序**绑定：第一个发起任何模型调用的活跃会话认领第一份有序脚本（即父会话：`createdAt` 最早，且必然最先流式输出，因为它必须先运行一个轮次才能委派），下一个新活跃会话认领下一份脚本，依此类推。此后每个会话独立推进自己的游标。
+
+这种方式按谁在调用键控，而非按全局调用顺序。因此即使 subagent 将来并发或在后台运行（全局游标会导致交错），它仍然正确。不携带 `sessionId` 的调用（直接在单元测试中调用 `stream()`）被视为一个匿名会话、绑定到主脚本，因此单会话路径与旧行为逐字节一致。活跃会话数多于录制脚本数时会快速失败报错（出现了未录制的 subagent），绝不会静默错误路由。
+
+子 fixture（测试前置数据）按 `createdAt` 排序，在兄弟会话严格顺序执行时与调用顺序一致。id 平局打破仅使退化碰撞具有确定性。并发或后台子会话必须引入显式的首次调用序号，而非依赖时间戳。
+
+## 曾考虑的替代方案
+
+曾考虑但否决的方案是：**将父子日志按调用顺序合并**为一份全局脚本（仅在进程内 subagent 执行严格嵌套——父 agent 阻塞等待子 agent——时才正确）。对当前的同步裁剪而言更简单，但将「父阻塞于子」这一不变式固化了进去；未来若引入后台/并发 subagent 就会失效。逐会话键控则不会。
+
+### 3. harness 收集所有日志，主会话优先
+
+`harvestSessionLogs` 递归收集 sessions 根目录下所有固定命名为 `session.jsonl` 的 transcript（JSONL 后端为每个父会话和子会话分别提供独立的项目/会话目录），解析各自的 header，并按主会话优先排序：顶层会话（无 `parentSession`）在前，各子会话按 `createdAt` 升序排列。`RunResult.sessionLogs` 是复数结果；spec 在录制时将每份日志写回对应 fixture（`session.jsonl` + `session.<n>.jsonl`），在回放时将每份收集到的日志与其 fixture 做 diff。归一化器已支持复数会话 id 并会折叠任何游离 UUID，因此无需修改归一化器。
+
+### 4. 场景
+
+新增两个嵌套场景，均对真实 API 录制：
+
+- **`subagent-spawn`**：父 agent 通过 `subagent` 工具将一个子任务委派给一个新 spawn 的子 agent（2 个会话）。
+- **`subagent-multi`**：父 agent 委派两个子任务，各自交给自己的 spawn 子 agent（3 个会话），以三份并行脚本和同一父 agent 下两个子会话的 `createdAt` 排序来压测逐会话键控。
+
+两者均在默认门禁中以 keyless 方式回放。
+
+## 后果
+
+- `TODO(subagent-snapshots)` 延期项已解决：嵌套 agent 的 transcript 现在是快照层的一等形态。
+- `GenerateOptions.sessionId` 是一个小而诚实的 core-seam 新增，在回放之外同样有用（遥测、请求路由）。
+- `subagent` 工具绑定到单一提供方，因此 `subagent-multi` 中的两个子 agent 都是 spawn（全新创建）。键控按会话路由而非按后端路由，因此对 fork 同样正确。但脚本*派生*逻辑此前不正确：fork 子会话的日志以种子化的父前缀（父会话的 `assistant/chunk` 事件）开头，如果从完整日志派生脚本，就会把父 agent 的响应当作子 agent 的来回放。这一正确性缺口通过持久化种子边界来弥合——见[持久化种子边界，使 fork 子项重放能够正确路由](2026-06-22-fork-child-replay-seed-boundary.md)——录制的 fork 与混合 spawn+fork 场景现在通过一份 transcript 同时验证两种传输方式（见[记录 fork 与混合 spawn+fork 快照场景](2026-06-22-fork-snapshot-scenarios.md)）。
+- 进程外（ACP（Agent Client Protocol））subagent 是完全不同的回放形态（每个子 agent 是自己的进程、有自己的回放），作为 `TODO(acp-subagent-replay)` 记录在 PR3 计划中。

## Problem
The hook bridges — [`dsh-hooks-claude`](../../../../packages/hooks/hooks-claude) (7 Claude Code hook points) and [`dsh-hooks-codex`](../../../../packages/hooks/hooks-codex) (5 Codex points) — map external hook commands onto the harness interception seams. They carry deep unit and coverage-spec coverage (every decision arm, every payload dialect, driven against a mocked seam) plus one key-gated e2e (`hooks.e2e.ts`, a live `PreToolUse` block). But the full-transcript snapshot tier — the one net that boots the real `acp-agent` subprocess, replays a recorded session keyless, and diffs the normalized ACP stdout + re-persisted log against committed expected outputs — covered exactly ONE hook: a Claude `UserPromptSubmit` block (`hook-cc-promptsubmit-block`).
-That is the tier a mocked unit test structurally cannot be: it exercises the REAL bridge translating a REAL hook process's outcome into the REAL seam decision, then the REAL loop's reaction, rendered exactly as an editor sees it. A bridge-translation or loop-structure regression that left every unit green would still escape it for every hook point but one — and for the Codex bridge, the ACP example did not even LOAD it, so no Codex hook could fire end-to-end at all.

+# Agent Note: 钩子快照矩阵——覆盖两种 bridge 的端到端预期输出测试
+
+Status: implemented
+
+[English](2026-07-04-hook-snapshot-matrix.md) | 中文
+
+## 问题
+
+钩子 bridge——[`dsh-hooks-claude`](../../../../packages/hooks/hooks-claude)（7 个 Claude Code 钩子点）和 [`dsh-hooks-codex`](../../../../packages/hooks/hooks-codex)（5 个 Codex 点）——把外部钩子命令映射到 harness 拦截 seam。它们有深入的单元与覆盖率规格覆盖（每个决策分支、每种 payload dialect，针对 mock seam 驱动），外加一个受密钥门控的 e2e（`hooks.e2e.ts`，实时 `PreToolUse` 阻止）。但完整 transcript（文本记录）快照层——会启动真实 `acp-agent` 子进程、无需密钥重放已记录会话，并将规范化 ACP（Agent Client Protocol）stdout + 重新持久化日志与已提交预期输出进行 diff 的那张网——只覆盖了一个钩子：Claude `UserPromptSubmit` 阻止（`hook-cc-promptsubmit-block`）。
+
+这正是 mock 单元测试在结构上无法替代的层级：它验证的是真实 bridge 将真实钩子进程的结果翻译到真实 seam 决策，再经由自动化线协议和持久化日志检验真实 agent loop（智能体循环）的反应。一个 bridge 翻译或 loop 结构的回归，即使让所有单元测试保持绿色，也会在除那一个钩子点之外的所有点上逃逸；而对于 Codex bridge，ACP 示例甚至没有加载它，因此没有任何 Codex 钩子能端到端触发。
+
+## 决策
+
+实现由两个耦合部分组成：
+
+### 1. ACP 示例同时加载两种钩子 bridge
+
+`examples/acp-agent/cordis.yml` 和 `cordis.snapshot.yml` 现在同时加载 `dsh-hooks-codex` 与 `dsh-hooks-claude`，各自指向自己的配置文件（Claude 用 `./hooks.json`，Codex 用 `./codex-hooks.json`——两种方言无法共用一个文件）。这是一个真正的产品接口变更，而非仅用于测试的接线：交付的 ACP 服务器（以及 `demo:acp` 入口）现在同时携带两种 bridge。
+
+这是安全的，因为配置文件不存在时 bridge 是**静默无操作**的：`apply()` 捕获读取失败、通过 `ctx.logger` 记录日志、不注册任何东西——零监听器、零会话事件。`acp-agent` 应用不附带 stdout logger，因此警告不会到达 ACP JSON-RPC 通道。只需要 Claude 钩子的场景（或真实项目）只提供 `hooks.json`；Codex bridge 找不到 `codex-hooks.json` 便自动消失。这已通过实验验证：在两种 bridge 同时加载的情况下，所有既有快照（均不附带 `codex-hooks.json`）逐字节一致。
+
+同时加载是让快照层能够在产品交付的同一个真实应用上验证每种方言的最低要求。录制（启动 `cordis.yml`）天然加载两者，回放以同样方式继承：`cordis.snapshot.yml` 是 `cordis.yml` 的 include-overlay，只替换 llm 入口（见[单一来源 acp-agent 回放配置](2026-07-04-single-source-acp-replay-config.md)），因此添加到运行时树的 bridge 无需第二次编辑即出现在回放树中。
+
+### 2. 每个钩子点 × 其主要结果各一个快照场景，覆盖两种方言
+
+`examples/acp-agent/tests/snapshots/` 下共 13 个场景，命名为 `hook-<dialect>-<point>-<outcome>`：
+
+- **手工编写、无模型轮次**（无密钥、无 sidecar——派生的回放脚本为空；比对的是携带 `hook/*` 事件的 `rejected` 轮次）：`hook-cc-promptsubmit-block`、`hook-codex-promptsubmit-block`。
+- **对真实 API 录制、录制期间钩子活跃**（模型对决策的反应是捕获的 transcript 的一部分，此后无密钥回放）：`hook-{cc,codex}-promptsubmit-context`（allow + additionalContext 折叠）、`hook-cc-pretool-deny` / `hook-codex-pretool-block`（deny → `isError` 工具结果）、`hook-cc-pretool-ask`（ask → 降级为 deny 并附带 approval-required 原因）、`hook-{cc,codex}-posttool-block`（阻止并附带反馈）、`hook-{cc,codex}-posttool-context`（accept + additionalContext）、`hook-{cc,codex}-stop-continue`（阻塞性 Stop 钩子通过 steering（中途引导）强制多走一步）。
+
+每个钩子命令只输出固定字面量字符串（无时间戳/pid/`$RANDOM`/cwd 回显）；快照规范化器擦除 `hook/result` 携带的唯一不稳定字段（`durationMs`）。`Stop` 场景通过标记文件（`.stop_fired`）自限，使 force-continue 不会循环——`stop_hook_active` 循环守卫仍是 bridge 的一个 `TODO`，因此无条件的 Stop 钩子会在每一步都 force-continue。
+
+`PostToolUse` 阻止场景会在其证明的机制处自行限制。Claude 钩子在首次拒绝后持久化一个 workspace 标记，因此允许一次恢复调用；Codex 提示词发起一次调用并报告注入结果。每份预期输出固定一次遭阻止调用，不会重复阻止/重试循环。
+
+### 三个钩子点被有意排除在快照之外
+
+在构建矩阵过程中发现，记录于此是因为这些遗漏是决策而非疏忽：
+
+- **`SessionStart` 和 `SubagentStart`** 通过脱离且尽力而为的 `void runPoint(...).then(agent.inject())` 注入上下文，没有轮次绑定。由此产生的 `context/message` 会与它应先于的工作（首次模型请求 / 子项的第一个轮次）竞速，并落在不确定的日志位置。记录的预期输出甚至无法在自己的重放中复现——对两者执行 10 次重放稳定性检查，结果均为 10/10 次失败。它们继续留在 bridge 的单元覆盖率中，那里会直接驱动 seam 而不存在时序竞速。（如果注入未来改为绑定轮次且具备确定性——`TODO(session-start-gating)` 所指方向——它们就能接受快照测试。）
+- **`SubagentStop`** 只观察：其 `subagent/end` handler 不传递轮次（因此没有 `hook/*` 日志事件），也不执行注入。它不会向 transcript 写入任何内容，因此预期输出会与无钩子运行逐字节相同，永远无法证明失败——一道咬不住问题的守卫。它继续由单元覆盖率负责（`bridge.spec.ts` 已断言仅观察调用）。
+
+因此，该矩阵覆盖了所有具有确定性、可观测 transcript 足迹的钩子点，涵盖两种方言。
+
+## 后果
+
+- 现在，两种 dialect 中每个具有可观察 transcript 的 bridge seam 映射，都在真实应用的完整 transcript 层受到守护——包括此前完全没有端到端覆盖的 Codex bridge。记录的预期输出捕获模型对遭拒绝/遭阻止/强制继续轮次的真实反应，而手工编写的 transcript 只能猜测这种反应。
+- `UserPromptSubmit` 阻止场景无需密钥即可编写（没有模型轮次）；其余场景从已记录 fixture（测试前置数据）无需密钥重放。`pnpm run test:snapshot:record` 从实时 API 重新生成记录式 fixture，并像所有记录场景一样在缺少密钥时自行跳过。
+- 证明会变红的准则仍成立：篡改钩子配置输出（例如改变拒绝理由）会让相应场景在重放时变红——钩子进程在重放期间真实运行（只有模型被重放），因此预期输出守护的是实际钩子→seam→循环路径，而非其 mock。
+- `acp-agent` 演示现在加载了一个通常会无操作的 Codex bridge（典型项目中没有 `codex-hooks.json`），这正是预期的柔性失败行为，而非代价。

## Problem
`examples/acp-agent` shipped two hand-maintained configs: `cordis.yml` (the live tree) and a `cordis.snapshot.yml` that mirrored it entry-for-entry with only the llm backend swapped — stripped of comments, the entire difference was the eight-line `llm-deepseek` stanza versus the two-line `llm-replay` stanza. Every app-shape change had to be made twice, and nothing gated the symmetry: if the copies drifted, the snapshot tier would silently exercise a different app than the one that ships — the ["green units, broken product" class of gap](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md) the snapshot tier exists to close, reintroduced one level up, with reviewer vigilance as the only defense.

+# Agent Note: 将 acp-agent 回放配置改为单一来源
+
+Status: implemented
+
+[English](2026-07-04-single-source-acp-replay-config.md) | 中文
+
+## 问题
+
+`examples/acp-agent` 发布了两份手工维护的配置：`cordis.yml`（实时树）和逐条镜像它、只替换 llm 后端的 `cordis.snapshot.yml`——去除注释后，两者的全部差异就是八行 `llm-deepseek` stanza 与两行 `llm-replay` stanza。每次应用形状变化都必须修改两遍，也没有任何机制约束对称性：如果副本发生漂移，快照层会悄然覆盖与已发布应用不同的应用——快照层本就是为了弥合[“单元测试绿色，产品损坏”这类缺口](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md)，如今同类缺口在上一层重新出现，只能依靠评审者警惕。
+
+## 决策
+
+`cordis.snapshot.yml` include 正式配置，通过 id 和 name 禁用指定的 DeepSeek 适配器，并插入回放适配器。其余所有条目因此来自正式运行树。回放时选择 overlay；录制仍然启动 `cordis.yml`，加载守卫允许被有意禁用的条目。
+
+overlay 有意依赖一项 vendored 插件事实：include 加载文件时会应用 `patches`，而其 `refresh()`/`internal/update` 路径会重新读取但不重新打补丁——这恰好足以满足一次性重放启动（重放应用不加载 `hmr`，运行中也没有内容重写配置）。快照套件就是证明：所有场景都能在 overlay 上原样通过，包括逐字节相同的预期输出。
+
+## 曾考虑的替代方案
+
+### 为何不采用这些替代方案？
+
+保留完整的双副本并加一道对称性校验门禁是记录在案的退路——它能消除静默漂移这一类问题，但仍保留一份 125 行的近乎复制品，其全部内容只是一个条目的差异，且随应用每增加一个插件而增长。在 bin 侧做替换（解析配置、替换条目、删除文件）则会把 YAML 手术放进发布产物，并把回放差异藏到视线之外；overlay 让差异保持声明式、可读，且紧邻基础配置——这正是双副本支持者真正看重的教学价值。
+
+## 后果
+
+- 向 `cordis.yml` 添加插件即自动进入回放树，无需第二次编辑；漂移这一类问题从结构上消失，而非靠门禁拦截。
+- overlay 依赖条目携带稳定的 `id:`。禁用补丁上的 `name` 断言防止误定位（id 被复用时补丁跳过而非禁用错误的插件）。如果 id 被重命名，补丁退化为跳过，其警告需要一个回放应用有意不具备的 logger——可观测结果是一条无效的无密钥 `llm-deepseek` 条目与 `llm-replay` 并存，回放输出仍然正确（`llm-replay` 拥有流的短路权）；这属于配置腐烂，留给评审发现，不会产生错误的快照。顶层插入一个 id 与既有条目冲突的新条目时，loader 的 id map 以后者为准；当前配置无冲突，新增补丁行才是引入冲突的场所。
+- 如果未来回放树需要第二处差异（另一个后端被替换），只需多加一行补丁，而非再 fork 一份文件。

## Problem
An ACP snapshot suite needs to prove the exact composed system prompt and tool-schema list sent in each `request/header`, but duplicating that content inside every `session.jsonl` makes a prompt or schema edit rewrite dozens of giant one-line JSON records. Keeping one raw header avoids the duplication but still makes prompt review poor: prose is JSON-escaped onto one line and mixed with thousands of characters of tool schemas.

+# Agent Note: 在单个快照场景中固定请求头内容
+
+Status: implemented
+
+[English](2026-07-06-pin-request-header-content-in-one-scenario.md) | 中文
+
+## 问题
+
+一个 ACP（Agent Client Protocol）快照测试套件需要证明每个 `request/header` 中实际发送的组合系统提示词与工具 schema 列表，但如果在每个 `session.jsonl` 中重复这些内容，一次提示词或 schema 编辑就会改写数十条巨大的单行 JSON 记录。保留一份原始 header 可以避免重复，但提示词的评审体验仍然很差：行文被 JSON 转义到一行中，与数千字符的工具 schema 混在一起。
+
+## 决策
+
+每种请求头组合类别恰好有一个场景标记为 `pinsHeader`。其目录按评审格式拆分固定内容：`system-prompt.expected.md` 以普通 Markdown 包含规范化的完整提示词序列；`tool-schemas.expected.json` 以结构化 JSON 包含对应的完整 schema 序列；`session.jsonl` 保留 config、reason 和所有模型可见前缀，同时将 `header.system` 与 `header.tools` 存为 `"{{system}}"` / `"{{tools}}"`。其他每份 JSONL 都使用相同的提示词与工具 token，并同样将会话前缀内容 token 化。固定机制位于 [`dsh-acp-snapshot`](../../../../packages/support/acp-snapshot/README.md)，其套件 factory 强制每种类别恰好有一个固定场景。
+
+纯 `scrubSystemPrompts` 和 `scrubToolSchemas` 规范化器会分别将每个已存储完整请求头 token 化。`scrubRequestHeaders` 还会为非固定场景把会话前缀内容 token 化，同时保留请求头数量、字段存在性、config、reason 和前缀消息数量。记录与刷新写回会在写入 JSONL 前应用适当清理，并根据规范化的实时完整请求头序列重新生成两个 sidecar，因此两条路径都无法把大段提示词/schema 重新引入 JSONL，也不会留下陈旧的评审产物。
+
+守卫使这种拆分能够自我强制。在磁盘上，每个 `session*.jsonl` 都是提示词和 schema 清理器的固定点；只有非固定 fixture（测试前置数据）必须是完整请求头清理的固定点；两个 sidecar 恰好位于固定 fixture 旁，并采用规范、以换行符结尾的格式；每种类别都有一个固定场景。在实时运行中，由父项、spawn 子项、fork 子项、初始请求、恢复或实例内变化产生的每个 `request/header`，都必须在易变值规范化后与重建的类别序列匹配。请求头若没有字符串提示词、没有数组值工具列表，或超过固定场景声明的变更请求头数量，就会响亮失败。
+
+一个固定场景覆盖整个套件，因为每个会话（parent、spawn 子会话、fork 子会话）组合出的工具列表完全相同、提示词除 cwd 外完全相同，而一致性守卫会在这一前提不再成立时立即使套件失败。如果 header 组合将来在设计上变为会话相关的（例如受限的 subagent 工具集），那么分歧的形态将获得自己的固定场景。
+
+## 曾考虑的替代方案
+
+- **每次变更重新录制或手动编辑所有 fixture**：保留了精确的 header，但行为差异被重复的提示词和 schema 内容淹没。
+- **仅在比较时 scrub，fixture 保持原始内容**：比较能通过，但已提交的 fixture 保留着陈旧的重复内容，下次录制时会整体重写。存储 token 诚实地表明每个 JSONL 没有固定什么。
+- **全部 scrub，不做任何固定**：丢失了组合 header 实际发送内容（提示词组装、已注册工具顺序、完整 schema）的唯一端到端记录。生成的工具目录只孤立地记录每个工具；只有真实 fixture 才能固定组合后的完整集合。
+- **将完整固定内容全部保留在 JSONL 中**：消除了套件范围的重复，但提示词和 schema 变更仍然是一行转义文本。Markdown 和结构化 JSON 为每种内容提供其自然的评审格式，同时不削弱重建 header 的断言。
+- **收窄会话日志本身（记录内容 digest，把请求头存到其他位置）**——违反可重建性契约：产品日志必须逐 bit 复现每个请求（[可重建请求 Agent Note（agent 决策记录）](../architecture/2026-07-05-reconstructable-requests.md)）。请求头体积是测试产物问题，应在测试规范化中解决；实时日志保持不变。
+
+## 验证
+
+该套件针对拆分后的固定内容回放每个场景。单元覆盖率会覆盖独立与完整清理器、两种完整请求头 sidecar 格式、记录/刷新重新生成、规范化提示词/schema 提取、固定点强制、必需文件对称性、重建请求头一致性，以及变更请求头数量拒绝。
+
+## 后果
+
+系统提示词变更在每个受影响的组合类别中产生一个面向行的 Markdown diff；工具描述变更在每个类别中产生一个结构化 JSON diff；普通行为 fixture 不受影响。会话 fixture 对省略的内容显示 token，运行时一致性守卫使每个拆分固定场景对其类别内的所有会话具有权威性。每个固定场景携带两个生成的、换行规范化的 sidecar 文件。

The ACP snapshot tier ([snapshot Agent Note](2026-06-19-acp-snapshot-tests.md)) was built from three modules living inside one example's test directory: `snapshot-harness.ts` (boot the real bin subprocess, drive it over ACP JSON-RPC, harvest the persisted logs), `snapshot-normalize.ts` (the pure expected-output normalizers), and the ~150-line scenario body plus fixture guards in `acp.snapshot.ts` (record/replay modes, the stdout expected-output and log comparisons, the pinned-header uniformity guard, the orphan/required-file/single-pin meta-tests).

+# Agent Note: 将 ACP 快照套件提取为支持包
+
+Status: implemented
+
+[English](2026-07-08-shared-acp-snapshot-package.md) | 中文
+
+## 问题
+
+ACP（Agent Client Protocol）快照层（[快照 Agent Note（agent 决策记录）](2026-06-19-acp-snapshot-tests.md)）由位于一个示例测试目录内的三个模块构建：`snapshot-harness.ts`（启动真实 bin 子进程，通过 ACP JSON-RPC 驱动它，采集持久化日志）、`snapshot-normalize.ts`（纯预期输出规范化器），以及 `acp.snapshot.ts` 中约 150 行的场景主体与 fixture（测试前置数据）守卫（记录/回放模式、stdout 预期输出与日志比较、固定请求头一致性守卫、孤立项/必需文件/单一固定项元测试）。
+
+第二个希望获得快照覆盖的 ACP 示例——直接消费方是沙箱/approval 组合——只能复制这些模块，恰好分叉了绝不能漂移的逻辑：记录写回、请求头清理、子会话采集顺序。spawn/client 胶水也在 `acp.e2e.ts`、`hooks.e2e.ts` 和 harness 中重复三份。文件位置决定了测试严格度：逐文件 100% 覆盖率门禁只测量 `packages/*/*/src`，因此这些机制完全未被测量——正是同一种缺口，曾推动 `dsh-llm-replay` 从 `examples/` 移入 [packages/support](../../../../packages/support/README.md)。此外，harness 的 ACP client 硬编码 `requestPermission → cancelled`，因此 approval 往返——沙箱组合的主打行为——完全无法在快照层表达。
+
+## 决策
+
+这些机制位于 [`packages/support/acp-snapshot`](../../../../packages/support/acp-snapshot/README.md)（`@deepseek-ai/dsh-acp-snapshot`）；示例的 `*.snapshot.ts` 只包含场景表、agent 路径和一次工厂调用，依赖自己的 `snapshots/` fixture 与 `cordis.snapshot.yml` overlay（[单源回放配置](2026-07-04-single-source-acp-replay-config.md)）。读取 `DSH_SNAPSHOT` 留在边缘层——库接收的是已解析的 `mode`。
+
+**`src/launcher.ts`**——`launchAcpTestAgent` 拥有通用的未构建进程边界：绝对 tsx loader 解析、`TSX_TSCONFIG_PATH`、隔离的 harness home、stdio 接线、原始字节 stdout tee、stderr 与更新捕获、失败关闭的权限后备、更新 waiter，以及优雅或信号式关闭。快照场景和普通 e2e 套件提供相同的 `AgentUnderTest`（`binScript`、`configPath`、`tsconfigPath`）；扮演用户的测试只提供其权限 handler。ACP 与钩子 e2e 套件以及沙箱/approval e2e 套件都使用该 launcher，而不再重新构建 SDK client 边界。
+
+**`src/harness.ts`**——`runScenario` 和输入脚本/结果类型在 launcher 之上叠加确定性步骤、临时 workspace、快照环境和持久化日志采集。其 `session/request_permission` handler 消费可选的 `InputScript.permissionAnswers` FIFO 队列，每个条目按选项**类型**进行选择（id 是 agent 生成的随机值，已提交脚本无法预知；类型是 ACP 稳定词汇，会在回答时映射到已提供的 `optionId`）；队列不存在或耗尽时回答 `cancelled`，若请求从未提供某种类型则拒绝该次运行——agent 自身收到的回答是 `cancelled`，因此场景 bug 会使 harness 失败，而不会被吸收为 agent 侧拒绝。由此，approval 套件可以根据 `input.json` 确定性地驱动允许/拒绝往返。
+
+**`src/normalize.ts`** 是纯规范化器，按策略不含钩子：当未来某个事件携带新的易变字段（例如审批耗时），共享规范化器在同一个变更中学会它，保持「规范化」的含义只有一个归属，而非各套件各自扩展清洗逻辑。
+
+**`src/suite.ts`**——包含 `Scenario` 类型和 `defineAcpSnapshotSuite(options)`，注册各场景比较、记录/刷新 fixture 写回、带实时一致性守卫的请求头固定项，以及 fixture 守卫块（没有孤立场景目录、必需文件存在、每种类别恰好一个固定项、每份 JSONL 都是 `scrubSystemPrompts` 固定点、非固定 fixture 同时也是 `scrubRequestHeaders` 固定点）。刷新会先展开打包的计时信封，再对齐现有易变事件时间，因此在打包与未打包布局之间切换不会移动后续记录；全新的分片片段数组仍为权威，因为其边界属于回放行为。场景目录中的 `session.jsonl` 加连续的 `session.<n>.jsonl` 同级文件构成有序主项/子项清单，因此场景表可以声明策略而不重复子项数量。固定请求头契约（[固定请求头 Agent Note](2026-07-06-pin-request-header-content-in-one-scenario.md)）按套件生效：每种请求头类别恰好标记一个 `pinsHeader` 场景，其 `system-prompt.expected.md` 和 JSONL 工具列表把组合请求头拆成可评审产物；一致性守卫会将两者与该类别的每个实时请求头比较。固定场景可以声明任何合法的变更请求头数量，其 Markdown 产物记录每个完整的已变提示词。纯辅助函数（`sessionFixtureNames`、`fixtureContext`、`normalizedHeaders`、`normalizedSystemPrompts`、`formatSystemPromptSnapshot`、`headerChangeCount`）从模块导出，以便直接进行单元覆盖。
+
+## 曾考虑的替代方案
+
+- **把模块复制到每个示例中**——这正是本 Agent Note 要防止的分叉：记录/守卫逻辑恰好是必须在各套件间保持逐字节相同的代码，而示例位于覆盖率门禁之外，所以每份副本也都无法测量。
+- **在 `examples/` 下建共享模块目录**：代码仍在覆盖率门禁之外，且需要跨示例边界的相对导入，违反包名导入约定；`examples/` 的叶子节点按设计应保持轻薄。
+- **`dsh-acp-demo` 的 `/testing` 子路径导出**：将测试基础设施耦合到产品包的对外服务接口与依赖集中；`packages/support/` 的存在正是为了真实但兼容性承诺较低的开发/测试包，`dsh-llm-replay` 是先例，本包与之配套。
+- **导出原始测试体函数而非套件工厂**：每个示例将重新拥有 `describe`/`it` 骨架（每套件约 80 行注册样板），却无灵活性收益；工厂使消费方只需一张场景表加一次调用，而导出的纯辅助函数在工厂设计内保留了可单元测试性。
+- **使用可注入 ACP `Client` factory 代替声明式 `permissionAnswers`**——灵活性最大，但会把 SDK client 构造泄漏给每个消费方，并恰好在正在统一的层重新引入逐示例漂移；声明式队列让 `input.json` 保持为唯一脚本表面，并与预期输出规范化兼容。
+- **泛化到 ACP 之外（传输无关的快照 harness）**：不存在第二种传输方式；harness 端到端都是 ACP 形态（SDK 客户端、JSON-RPC 帧、`session/update` 等待器），推测性的抽象将是一个超前于任何消费方的 seam 拆分。
+
+## 测试
+
+提取一致性得到机械证明：迁移后，`pnpm run test:snapshot` 的结果与基准提交匹配，`examples/acp-agent/tests/snapshots/` 下没有任何字节变化。包的 `src/` 在门禁单元运行中保持逐文件 100% 语句/分支/函数/行覆盖，并通过脚本化 fake ACP bin（`tests/fixtures/fake-acp-agent.ts`，每个场景由 fixture 旁的 `behavior.json` 编排行为）经过真实 launcher 驱动：`harness.spec.ts` 直接覆盖 launcher 默认值、捕获、更新等待、关闭以及环境/配置变体，随后覆盖每种场景步骤操作、两个 expect-error 分支、权限队列（选择、后备、不可能点击）、workspace seed，以及采集顺序/噪音/后备分支；`suite.spec.ts` 在收集时真实运行 factory——一个针对已提交合成 fixture 的回放套件和一个针对临时副本的记录套件（写回从不触及已提交树；`ACP_SNAPSHOT_SPEC_BOOTSTRAP=1` 会重新引导它）——并包含纯辅助函数的直接用例。fake bin 会把 `session/new` cwd 而非 `process.cwd()` 代入脚本化日志，与真实 bin 请求头携带的内容一致（darwin 会将 `/var/folders/…` realpath 为 `/private/var/folders/…`）。
+
+## 后果
+
+新示例通过场景表加 fixture 即可获得完整快照层，普通 ACP e2e 则通过一次 launcher 调用获得同一条经过测试的进程/client 边界。代价是：`suite.ts` 导入 vitest，因此包入口只能在 vitest 运行中导入——其他包都没有这种形状，其 README 已说明；每个套件还要固定自己的约 8 KB 请求头 fixture（真正不同的组合理应拥有自己的固定项；相同组合则会被该套件的一致性守卫捕获）。

+# Agent Note: Keyless browser e2e lane for the web GUI
+
+Status: implemented
+
+English | [中文](2026-07-24-web-gui-browser-e2e-lane.zh.md)
+
+## Problem
+
+The web GUI ships as a real assembled chain — chromium page → client plugin bundles → HTTP unary RPC + two SSE streams → `toFetchHandler`/apiproxy → the host agent loop, tools, and JSONL persistence — and no test exercised that chain keylessly and deterministically. The [GUI testing system](../process/2026-07-20-gui-testing-system.md) covers tier 1 (wire isomorphism in node), tier 2 (object-layer state machines), and tier-3 smokes, but the keyless smoke drives `FixtureApiClient` — no host, no wire, no agent loop — while the full-chain smoke needs `DEEPSEEK_API_KEY` and a live model, so it is nondeterministic and self-skips in keyless CI. The snapshot philosophy of [docs/testing.md](../../../../docs/testing.md) — record once with a key, replay forever keyless, refresh on format churn — already covers the ACP, headless `stream-json`, and TUI transcript surfaces; the web surface was the one assembled product shape without it. The gap is exactly where the two confirmed GUI P0s hid: the wire carriage chain the fixture client short-circuits.
+
+## Decision
+
+`pnpm run test:web` carries a keyless, deterministic browser e2e lane under `apps/web/tests/`: recorded session-log fixtures replayed through `@deepseek-ai/dsh-llm-replay` against the real in-process web composition, asserting a normalized conversation aria golden plus in-process world state. No new package; the product deltas are two additive `dsh-llm-replay` surfaces (`paceMs`, `ReplayHandle`).
+
+### Scaffold: `apps/web/tests/scaffold.ts`
+
+A plain shared-fixture module (the [testing-policy sanctioned shape](../../../../docs/testing.md)), not a package: the gate-worthy logic — replay derivation, session parsing, log scrubbing, persistence — lives in the gated packages `dsh-llm-replay`, `dsh-acp-snapshot`, and `dsh-session-persistence-jsonl`; what remains is boot wiring and browser glue, and chromium-driving code cannot hold per-file 100% coverage on the browserless coverage runners.
+
+`launchWebScaffold()` boots the real web composition from the shipped `apps/cli/cordis.yml` through the vendored Loader's include mechanism — the same tree and mechanism `AppCLIEntry` drives for `dsh web`. Divergences ride include patches over that tree, the ACP `cordis.snapshot.yml` pattern expressed in-process: temp `persistenceRoot`, `workspace-context` disabled (recorded fixtures must not embed this repo's AGENTS.md), `session-title-llm` disabled (its fire-and-forget title call would race the loop for the session's replay cursor), the webserver row pinned to port 0 with the built dist, and in keyless modes `llm-deepseek` disabled. A patch id that stops matching a row fails the boot sweep loudly instead of drifting. The boot runs `chdir`'d to the temp workspace so the api-gateway's `process.cwd()` session default, tool cwds, and fixtures agree; the `dsh web` bin's own glue (argv, profile json, AppCLIEntry) stays held by the keyless CLI smokes in `smoke-real.e2e.ts`. Setup rollback and ordinary close both dispose the Cordis tree before removing the two owned temp roots, attempt every cleanup independently, and report cleanup failures without masking the setup failure.
+
+Keyless model displacement is the disabled adapter row plus `installLlmReplay` filling the open seam on the settled root ctx in providers-catalog mode — never catch-all: with the adapter row disabled no adapter exists, so catch-all would leave `resolveModelContext` unroutable and `compact-basic`'s post-step pressure check would warn every step instead of being provably inert (the published 128k `contextWindow` keeps it inert for small fixtures). The direct install rather than an inserted replay plugin row is deliberate: it returns the `ReplayHandle` the teardown consumption check needs. A scenario with no fixture leaves the seam empty, so a stray stream fails loud with NO_ADAPTER.
+
+`seedSession()` seeds cold sessions through the real persistence API — a throwaway `Context` mounting `SessionStore` + `SessionPersistenceJsonl` against the host's root, `create()` + `append()`, one `utimes` backdate for deterministic sidebar order (the `semantic-checkpoint.snapshot.ts` precedent) — never raw file writes, so the seeder knows nothing of bucket hashing, filename encoding, or compression, and the host's zstd default needs no boot knob. Seeds are validated at seed time (parseable, ending in `turn/end` — an open final turn would be mutated by resume's crash repair).
+
+### Determinism rules
+
+The barrier stack for replay-mode browser assertions is, in order: (1) host-side `await agent.whenIdle()` under a timeout, keyed off the in-process `turn/end` — the idle flip follows the persistence flush, so one await covers turn completion and durability; (2) browser settled poll (streaming detached, final text visible). Record-mode log harvest runs after `whenIdle()` and before scaffold disposal while the live session remains available. An in-process `turn/end` listener alone is a wrong barrier (it fires before the SSE frame reaches the browser and before the fsync); file polling is banned (slow on NFS, superseded by `whenIdle`); `networkidle` is banned outright (never resolves while an SSE stream is open).
+
+No single-shot transient-DOM assertions: every hop from replay yield to React commit can coalesce chunks, so sampling `[data-streaming]` is a race by construction. Streaming incrementality is asserted from the persisted `assistant/chunk` events (model-visible ⟺ logged makes the log the authoritative proof). `dsh-llm-replay`'s opt-in `paceMs` (default absent = burst) is a realism knob so the browser observes genuinely incremental SSE; correctness never leans on it, and abort during a pace wait cancels promptly.
+
+Every scenario fails on any pageerror and on the client's connection-loss/gap-repair console warnings: the reconnect machine plus history resync would otherwise self-heal a dead SSE path and the suite would certify a broken wire. Scaffold `close()` calls the `ReplayHandle.assertConsumed()` teardown check (every recorded script bound, every cursor drained), converting silent underruns and shifted bindings into crisp diagnostics. No vitest retry on the lane; one chromium per file, fresh context per scenario, one host per scenario; viewport pinned; interaction selectors anchor on roles, `data-*` attributes, and visible text, while the frame and conversation-region captures use the existing CSS-module local-name anchors.
+
+### Expected outputs
+
+One committed golden per scenario: a normalized `ariaSnapshot()` of the conversation region (`ui.expected.md`) — uuid/cwd/workspace-basename/duration tokens normalized, captured poll-until-equal at the settled milestone — plus a few role/text anchor assertions that stay green under a semantics-preserving component rewrite while the golden churns reviewably. The aria tree is the mechanization of the client rule "assert what the user would see, never class names". World-state assertions ride root-context session events inline (which tool call produced which durable result, whether `turn/end` completed) instead of a second committed log golden: the persisted-log surface is pinned by the ACP/headless/TUI suites through the same loop and persistence, and re-pinning it here would double refresh cost against the tier discipline. `refresh` is the sole golden writer — a missing golden in replay mode fails with the healing command rather than self-bootstrapping.
+
+The typecheck plane split is structural: the three files that boot the host spine (`scaffold`, `replay-round-trip.e2e`, and `seeded-history.e2e`) are excluded from the client-registered `apps/web` project. Those files and their shared `support.ts` are included file-by-file in `tsconfig.host.json` — one program cannot hold both sides of the cordis `Context` merges.
+
+### Modes and fixtures
+
+`DSH_SNAPSHOT` selects replay (default, keyless), record (with key), or refresh (keyless) as inline spec branches — the TUI shape, not a suite factory: at two scenarios the acp-snapshot factory machinery has no owner, and the genuinely shared parts are already exported (`scrubRequestHeaders`, `parseSessionLog`, `installLlmReplay`). Each spec splits into drive steps (type, send, `whenTurnSettled` — run in all modes, never waiting on model-content selectors, so record cannot hang on a live model answering differently) and assertion steps (replay/refresh only). Record = drive live through the real composer + harvest the in-memory `session.header`/`session.events` (the TUI `rawSessionLog` shape — no file decompression) + `scrubRequestHeaders` + `{{sessionId}}`/`{{cwd}}`/`{{rpcId}}` tokenization; a follow-up keyless refresh regenerates `ui.expected.md`. Both scenarios' fixtures were recorded against this assembly through this flow. A drift guard ties each spec's drive prompt to the fixture's recorded `user/message`. A fixture-inventory guard holds each scenario directory closed (exact file set, every JSONL a scrub fixed-point with no run-local `rpcId`). Web fixtures scrub headers everywhere and pin no header class, following the TUI precedent over the strict [pinned-header](2026-07-06-pin-request-header-content-in-one-scenario.md) reading — see Deferred.
+
+### Scenarios
+
+1. **`replay-round-trip`** — new session, prompt through the real composer, replay streams reasoning + a `bash` tool call that really executes in the temp workspace + final text (paced 15ms). Asserts settled markdown, the aria golden, and inline world state (the bash call's durable result is exactly `WEB_E2E_OK\n`, completed `turn/end`, >10 chunk events).
+2. **`seeded-history`** — a recorded session seeded cold; the sidebar lists it (group row → session row, collapsed by default), opening renders tool cards and text purely from the log through the implicit cold-resume attach inside `session.history` — zero model calls in replay, so no binding constraints; record mode drives the same turn live (real `read` tool against seeded workspace files) to produce the seed.
+
+### CI stance
+
+The lane ships gate-exempt inside `pnpm run test:web`, exactly as that config's header records. Adding chromium to CI would reverse the "no browser infrastructure in CI" premise in the [GUI testing note](../process/2026-07-20-gui-testing-system.md) and therefore requires its own Agent Note cross-linked from there, staged as a non-required job first with measured promotion criteria (consecutive green runs, wall time, zero-retry flake budget, runner browser-cache strategy). `TODO(ci-browser)` marks the seam. Scenarios are POSIX-oriented (the lane is not in the Windows matrix).
+
+## Prior art
+
+Surveyed AI-chat/agent web UIs and mocking layers (LibreChat, vercel/ai-chatbot + AI SDK, lobe-chat, open-webui, OpenHands, Chainlit, continue, cline, langfuse, gradio/streamlit; Playwright HAR/route, MSW, Polly/nock, WireMock, aimock). The dominant proven architecture for apps that own their backend is an in-process fake/replay model behind the real backend seam with everything downstream real (LibreChat's `LIBRECHAT_TEST_RUN_HOOK` fake model; ai-chatbot's `MockLanguageModelV3` + `simulateReadableStream`; continue's scripted mock provider classes) — which is what `dsh-llm-replay` already is. Browser-level SSE interception cannot exercise incremental rendering (`route.fulfill` delivers the whole body at once; playwright#33564) and leaves the server SSE stack untested, so projects use it only for edge cases. Chunk pacing as a fixture parameter recurs everywhere (LibreChat 10ms default with slow profiles; ai-chatbot 500ms); real models in CI rot (open-webui's suite grew 120-second timeouts, was disabled, then deleted); sessions are seeded at the persistence layer with controlled timestamps (LibreChat inserts backdated Mongo documents; langfuse seeds its DB). No surveyed project replays a recorded agent-event log through the real backend for UI tests — the closest are provider-level recorded fixtures (aimock) and frontend-level socket history emission (OpenHands MSW) — so the session-log-as-fixture design goes one step beyond prior art along the axis this repo's model-visible ⟺ logged invariant makes natural.
+
+## Alternatives considered
+
+**Browser-network SSE interception (`page.route`).** Rejected: `route.fulfill` cannot stream, so incremental token rendering is unexercisable and the server-side SSE/backpressure/close path — where both confirmed P0s hid — goes untested.
+
+**Mock HTTP provider at `DEEPSEEK_BASE_URL`.** Rejected as the lane's mechanism (kept for the one existing workspace-probe smoke): fixtures become hand-authored OpenAI SSE byte scripts, a second fixture format that drifts from the session-log format the rest of the repo records and replays; the adapter's real HTTP path is with-key e2e's job.
+
+**Growing the `?fixture` client.** Rejected: tier separation — `FixtureApiClient` exists to test the client shell without a server; everything below the client API seam stays untested by construction.
+
+**Placeholder `DEEPSEEK_API_KEY` + replay interception instead of disabling the adapter row.** Rejected despite zero composition change and two in-tree precedents: it satisfies `llm-deepseek`'s fail-loud key check with a lie and leaves a dead adapter mounted-but-intercepted; the disabled row (the ACP overlay's move) is honest keylessness and fails loud at the earliest resolvable point.
+
+**A `packages/support/web-snapshot` package with a `defineWebSnapshotSuite` factory.** Rejected: chromium-driving source cannot honestly hold per-file 100% coverage on browserless coverage runners, and at two scenarios a factory generalizes from one consumer while the genuinely shared logic is already exported from gated packages. Re-entry trigger: a second web-shaped consumer or ≥6 scenarios with demonstrably drifting inline branches; the package boundary would then be drawn browser-free.
+
+**A committed normalized-session-log golden as a second expected surface.** Rejected: the log surface is pinned by the ACP/headless/TUI suites through the same loop and persistence; here it would double refresh cost and re-test lower tiers. Inline world-state assertions on root-context events keep the world-verification duty.
+
+**Spawning the `dsh web` bin with a `DSH_SNAPSHOT` replay branch.** Rejected: it needs a test-only replay branch plus environment plumbing in the shipped CLI. The in-process scaffold already loads the same `apps/cli/cordis.yml`; only argv, profile JSON, and `AppCLIEntry` glue remain outside it, and the keyless CLI smokes cover those paths.
+
+**Changing the wire protocol for testability.** Rejected: the contract already has a first-class keyless isomorphic seam (`InProcessApiClient(toFetchHandler(api))`), the per-event unbatched SSE is exactly what makes replay observable in a browser, and testing a wire we no longer ship would invert the tier's purpose.
+
+**Real-model browser tests as the keyless lane.** Rejected: nondeterministic by construction; the surveyed cautionary case (open-webui) grew unbounded timeouts and was deleted. The with-key W5 smoke stays as the live-model complement.
+
+**A client `data-dsh-busy` settled signal.** Deferred: the multi-condition settled polls proved sufficient at two scenarios and the host-side `whenIdle` barrier does the heavy lifting. Re-entry trigger: the first settled-poll flake, or a scenario needing a state the DOM does not expose.
+
+## Testing
+
+The lane itself: `pnpm run test:web` runs both scenarios keylessly alongside the existing smoke pair; `DSH_SNAPSHOT=record pnpm exec vitest run --config vitest.web.config.ts apps/web/tests/<spec>` re-records a scenario's fixture against the live model; `DSH_SNAPSHOT=refresh` rewrites both aria goldens keylessly. `paceMs` validation, pacing floor, abort-during-pace, and both `assertConsumed` failure shapes are pinned in `packages/support/llm-replay/tests/llm-replay.spec.ts`.
+
+## Deferred
+
+- **Web header-class pin**: web fixtures tokenize `{{system}}`/`{{tools}}` everywhere and no scenario pins the web composition's prompt/tool schemas (`TODO(web-header-pin)` — the scaffold `recordFixture` JSDoc marks it). Following the TUI scrub-everywhere precedent; revisit when the web assembly's header diverges from the repl composition it mirrors.
+- **CI browser provisioning**: reversal of the no-browser-in-CI ruling, staged criteria above (`TODO(ci-browser)`).
+- **Follow-up-prompt-after-resume scenario**: the history/live stitch path over the real wire; add as its own scenario when that code changes or regresses.
+
+## Consequences
+
+The web surface gains its record-once/replay-forever tier: the real chromium → SSE → apiproxy → loop → tools → persistence chain runs keylessly in ~10-30s, deterministic across repeat runs, with fixtures owned and re-recordable by the lane itself. Costs accepted: every intentional conversation-UI change ends with a keyless `DSH_SNAPSHOT=refresh` (golden churn is reviewed diff, anchors keep semantic green); the aria format is Playwright-owned — the one committed snapshot format the repo does not control — so playwright version bumps must be deliberate bump-and-refresh commits (the dependency floats `^1.49.0` in `apps/web/package.json`; pin exactly if churn bites); replay's first-call-order binding constrains scenarios to one prompting session each, with the consumption assertion as the tripwire; `compact-basic` shares the session's replay cursor and stays inert only under the published 128k catalog window; and the lane guards regressions only where it runs (locally, `test:web`) until the CI reversal is separately decided.

+
+## 问题
+
+Web GUI 以一条真实组装链交付——chromium 页面 → client 插件 bundle → HTTP 单次 RPC + 两条 SSE（Server-Sent Events）流 → `toFetchHandler`/apiproxy → host 端的 agent loop（智能体循环）、工具与 JSONL 持久化——却没有任何测试无密钥且确定性地检验这条链。[GUI 测试体系](../process/2026-07-20-gui-testing-system.md)覆盖第 1 层（Node 中的协议同构）、第 2 层（对象层状态机）与第 3 层冒烟测试，但无密钥冒烟驱动的是 `FixtureApiClient`——没有 host、没有 wire、没有 agent loop——而全链路冒烟需要 `DEEPSEEK_API_KEY` 和真实模型，因此不确定、在无密钥 CI 中自行跳过。[docs/testing.md](../../../../docs/testing.md) 的快照哲学——带密钥录制一次、永久无密钥回放、格式变动时刷新——已覆盖 ACP（Agent Client Protocol）、headless `stream-json` 与 TUI 三个文本记录（transcript）表面；web 表面是唯一没有这层保障的组装形态。而缺口恰恰是两起已实证 GUI P0 藏身之处：fixture（测试前置数据）客户端短路掉的 wire 承载链。
+
+## 决策

+`pnpm run test:web` 携带 `apps/web/tests/` 下的无密钥、确定性浏览器 e2e 车道：录制的会话日志 fixture 经 `@deepseek-ai/dsh-llm-replay` 对真实进程内 web 组合回放，断言规范化后的会话区 aria 预期输出加进程内世界状态。不新增包（package）；产品侧增量只有 `dsh-llm-replay` 的两处增量接口（`paceMs`、`ReplayHandle`）。
+
+### Scaffold：`apps/web/tests/scaffold.ts`
+
+一个普通的共享 fixture 模块（[测试政策认可的形态](../../../../docs/testing.md)），不是包：值得门禁把守的逻辑——回放推导、会话解析、日志脱敏、持久化——都在已受门禁的包 `dsh-llm-replay`、`dsh-acp-snapshot`、`dsh-session-persistence-jsonl` 中；剩下的只是启动接线和浏览器胶水，而驱动 chromium 的源码在无浏览器的覆盖率 runner 上无法诚实保持逐文件 100% 覆盖率。
+
+`launchWebScaffold()` 通过 vendored Loader 的 include 机制，从交付的 `apps/cli/cordis.yml` 启动真实 web 组合——与 `AppCLIEntry` 为 `dsh web` 驱动的是同一棵树、同一套机制。差异全部经 include patch 覆盖在这棵树上，即 ACP `cordis.snapshot.yml` 模式的进程内表达：临时 `persistenceRoot`；禁用 `workspace-context`（录制的 fixture 不得嵌入本仓库的 AGENTS.md）；禁用 `session-title-llm`（其发后不管的标题调用会与循环争抢会话的回放游标）；webserver 行钉到端口 0 加已构建 dist；无密钥模式下禁用 `llm-deepseek`。patch 的 id 一旦不再匹配任何行，boot 扫描会大声失败而不是漂移。boot 在临时工作区 `chdir` 下运行，使 api-gateway 的 `process.cwd()` 会话默认值、工具 cwd 与 fixture 一致；`dsh web` bin 自身的胶水（argv、profile json、AppCLIEntry）仍由 `smoke-real.e2e.ts` 中的无密钥 CLI 冒烟把守。初始化回滚和正常关闭都会先对 Cordis 树执行 dispose（资源释放），再删除 scaffold 持有的两个临时根目录；每项清理都会独立尝试，并会报告清理失败而不掩盖初始化失败。
+
+无密钥的模型替换 = 禁用适配器行的 patch 加 `installLlmReplay` 在停稳的根 ctx 上以提供方目录（providers-catalog）模式填充开放的 seam——绝不用 catch-all：适配器行被禁用后不存在任何适配器，catch-all 会让 `resolveModelContext` 无路由可走，`compact-basic` 的步后压力检查将步步告警，而不是被可证明地闲置（发布的 128k `contextWindow` 使该路径对小 fixture 保持闲置）。选择直接安装而非插入回放插件行是刻意的：直接安装返回收尾消费检查所需的 `ReplayHandle`。没有 fixture 的场景让 seam 保持空置，任何离群的流式调用都会以 NO_ADAPTER 大声失败。
+
+`seedSession()` 通过真实持久化 API 播种冷会话——一次性 `Context` 挂载 `SessionStore` + `SessionPersistenceJsonl` 指向 host 的根目录，`create()` + `append()`，一次 `utimes` 回拨保证侧栏顺序确定（`semantic-checkpoint.snapshot.ts` 先例）——绝不裸写文件，因此播种器对桶哈希、文件名编码、压缩一无所知，host 的 zstd 默认值也无需任何启动开关。种子在播种时即校验（可解析、以 `turn/end` 结尾——未闭合的最终轮次会被恢复（resume）的崩溃修复改写）。
+
+### 确定性规则
+
+回放模式下浏览器断言的屏障栈，按序：（1）host 侧 `await agent.whenIdle()` 加超时，以进程内 `turn/end` 为锚——空闲翻转发生在持久化落盘之后，一次等待同时覆盖轮次完成与持久性；（2）浏览器安定轮询（流式输出节点已卸载、最终文本可见）。录制模式下，日志采收在 `whenIdle()` 之后、scaffold 释放之前进行，此时运行中的会话仍然可用。单独监听进程内 `turn/end` 是错误屏障（它先于 SSE 帧到达浏览器、先于 fsync 触发）；文件轮询被禁止（NFS 上慢，且被 `whenIdle` 取代）；`networkidle` 被彻底禁止（SSE 流保持打开时它永不解析）。
+
+不做单次瞬态 DOM 断言：从回放产出到 React 提交的每一跳都可能合并分片，采样 `[data-streaming]` 天然就是竞态。流式输出的增量性由持久化的 `assistant/chunk` 事件断言（模型可见 ⟺ 已记录，使日志成为权威证据）。`dsh-llm-replay` 的可选 `paceMs`（默认缺省 = 突发）只是让浏览器观察到真正增量 SSE 的真实感旋钮；正确性绝不依赖它，且节奏等待期间中止会即时取消。
+
+每个场景都会因任何 pageerror 或客户端的连接丢失/间隙修复控制台警告而失败：否则重连机制加历史重同步会把一条死掉的 SSE 通路自愈掉，套件反而认证了坏 wire。Scaffold 的 `close()` 调用 `ReplayHandle.assertConsumed()` 收尾检查（每个已录脚本都被绑定、每个游标都耗尽），把静默的少放与错绑变成清晰诊断。车道不设 vitest 重试；每文件一个 chromium、每场景一个新 context、每场景一个 host；视口固定；交互选择器锚定 role、`data-*` 属性和可见文本，而 frame 与会话区采集则使用既有的 CSS 模块局部类名锚点。
+
+### 预期输出
+
+每场景一份提交的预期输出：会话区规范化 `ariaSnapshot()`（`ui.expected.md`）——uuid/cwd/工作区目录名/时长归一为稳定 token，在安定里程碑处轮询至两次相等再采集——外加几条 role/文本锚断言，让保语义的组件重写在预期输出可评审地变动时仍保持绿色锚点。aria 树是 client 规则「断言用户所见，绝不断言类名」的机械化。世界状态断言内联在根上下文的会话事件上（哪次工具调用产生了哪项已持久化的工具结果、`turn/end` 是否完成）而不是第二份提交的日志预期输出：持久化日志表面已由 ACP/headless/TUI 套件经同一循环和持久化钉住，在此重复钉住会违背分层纪律、翻倍刷新成本。`refresh` 是预期输出的唯一写入者——回放模式下预期输出缺失会连同修复命令一起报错，而不是静默自举。
+
+类型检查平面切分是结构性的：启动 host 主干的三个文件（`scaffold`、`replay-round-trip.e2e` 和 `seeded-history.e2e`）被排除出注册在 client 侧的 `apps/web` 工程。这三个文件及其共享的 `support.ts` 逐文件纳入 `tsconfig.host.json`——一个程序不能同时持有 cordis `Context` 合并的两侧。
+
+### 模式与 fixture
+
+`DSH_SNAPSHOT` 以内联 spec 分支选择 replay（默认，无密钥）、record（带密钥）或 refresh（无密钥）——TUI 的形态，不是套件工厂：两个场景撑不起 acp-snapshot 工厂机制，且真正共享的部分已被导出（`scrubRequestHeaders`、`parseSessionLog`、`installLlmReplay`）。每个 spec 切分为驱动步骤（输入、发送、`whenTurnSettled`——所有模式都执行，绝不等待模型内容选择器，因此 record 不会因真实模型答法不同而挂起）与断言步骤（仅 replay/refresh）。Record = 经真实输入框实时驱动 + 采收内存中的 `session.header`/`session.events`（TUI 的 `rawSessionLog` 形态——无需文件解压）+ `scrubRequestHeaders` + `{{sessionId}}`/`{{cwd}}`/`{{rpcId}}` token 化；随后一次无密钥 refresh 重新生成 `ui.expected.md`。两个场景的 fixture 都经此流程对本组装录制。一条漂移防线把每个 spec 的驱动提示词与 fixture 录制的 `user/message` 绑定。fixture 清单防线保持每个场景目录封闭（精确文件集合，每个 JSONL 都是脱敏不动点，不含当次运行的 `rpcId`）。Web fixture 全部脱敏请求头且不钉任何头类别，沿用 TUI 先例而非[钉住请求头](2026-07-06-pin-request-header-content-in-one-scenario.md)的严格读法——见「暂缓」。
+
+### 场景
+
+1. **`replay-round-trip`**——新会话，经真实输入框发送提示词，回放流式输出推理（reasoning）+ 一次在临时工作区真实执行的 `bash` 工具调用 + 最终文本（15ms 节奏）。断言安定后的 markdown、aria 预期输出与内联世界状态（这次 bash 调用的已持久化工具结果严格等于 `WEB_E2E_OK\n`、完成的 `turn/end`、>10 个分片事件）。
+2. **`seeded-history`**——冷播种一份已录会话；侧栏列出它（分组行 → 会话行，默认折叠），打开后纯凭日志经 `session.history` 内的隐式冷恢复挂载渲染工具卡片与文本——replay 下零模型调用，因此没有任何绑定约束；record 模式实时驱动同一轮（真实 `read` 工具读取播种的工作区文件）来产出种子。
+
+### CI 立场
+
+车道随 `pnpm run test:web` 交付、豁免门禁，与该配置头部注释所记一致。往 CI 加 chromium 会推翻 [GUI 测试笔记](../process/2026-07-20-gui-testing-system.md)中「CI 无浏览器基础设施」的前提，因此需要自己的 Agent Note 并从那里交叉链接，分阶段推进：先作为非必需任务，再以量化标准晋升（连续绿色运行次数、耗时、零重试的抖动预算、runner 浏览器缓存策略）。`TODO(ci-browser)` 标记该接缝。场景目前面向 POSIX（车道不在 Windows 矩阵中）。
+
+## 业界先例
+
+调研了 AI 聊天/agent web UI 与 mock 层（LibreChat、vercel/ai-chatbot + AI SDK、lobe-chat、open-webui、OpenHands、Chainlit、continue、cline、langfuse、gradio/streamlit；Playwright HAR/route、MSW、Polly/nock、WireMock、aimock）。自有后端的应用的主流成熟架构是：真实后端 seam 后放一个进程内伪造/回放模型，下游全部真实（LibreChat 的 `LIBRECHAT_TEST_RUN_HOOK` 伪模型；ai-chatbot 的 `MockLanguageModelV3` + `simulateReadableStream`；continue 的脚本化 mock 提供方类）——这正是 `dsh-llm-replay` 已然所是。浏览器层 SSE 拦截无法检验增量渲染（`route.fulfill` 一次性交付整个响应体；playwright#33564），且服务端 SSE 栈完全失测，因此各项目只把它用于边缘用例。分片节奏作为 fixture 参数反复出现（LibreChat 默认 10ms 附慢速档；ai-chatbot 500ms）；CI 里的真实模型会腐烂（open-webui 的套件长出 120 秒超时，先被禁用后被删除）；会话在持久化层以受控时间戳播种（LibreChat 直插回拨时间的 Mongo 文档；langfuse 播种其数据库）。没有任何被调研项目为 UI 测试把录制的 agent 事件日志经真实后端回放——最接近的是提供方层录制 fixture（aimock）与前端层 socket 历史发射（OpenHands MSW）——因此会话日志即 fixture 的设计沿着本仓库「模型可见 ⟺ 已记录」不变式所指的方向比业界先例多走了一步。
+
+## 曾考虑的替代方案
+
+**浏览器网络层 SSE 拦截（`page.route`）。** 已否决：`route.fulfill` 无法流式输出，增量 token 渲染无从检验，且服务端 SSE/背压/关闭路径——两起已实证 P0 的藏身处——完全失测。
+
+**`DEEPSEEK_BASE_URL` 处的 mock HTTP 提供方。** 作为本车道机制已否决（仅保留给既有的工作区探针冒烟）：fixture 会变成手写的 OpenAI SSE 字节脚本，一种与仓库其余部分录制回放的会话日志格式渐行渐远的第二 fixture 格式；适配器的真实 HTTP 路径归带密钥 e2e 管。
+
+**扩展 `?fixture` 客户端。** 已否决：分层纪律——`FixtureApiClient` 的存在意义就是脱离服务器测试客户端 shell；client API seam 以下按构造即失测。
+
+**用占位 `DEEPSEEK_API_KEY` + 回放拦截替代禁用适配器行。** 尽管零组合改动且树内有两处先例仍被否决：它用谎言满足 `llm-deepseek` 的快速失败密钥检查，还留下一个挂载却被拦截的死适配器；禁用行（ACP overlay 的同款做法）是诚实的无密钥，并在最早可解析点快速失败。
+
+**`packages/support/web-snapshot` 包 + `defineWebSnapshotSuite` 工厂。** 已否决：驱动 chromium 的源码在无浏览器的覆盖率 runner 上无法诚实保持逐文件 100%，且两个场景就上工厂是从单一消费方过度泛化，真正共享的逻辑已从受门禁的包中导出。重启条件：出现第二个 web 形态消费方，或 ≥6 个场景的内联分支被证实各自漂移；届时包边界将画在无浏览器一侧。
+
+**第二份提交的规范化会话日志预期输出。** 已否决：日志表面已由 ACP/headless/TUI 套件经同一循环与持久化钉住；在此只会翻倍刷新成本并重复测试下层。内联在根上下文事件上的世界状态断言保住了验证世界的义务。
+
+**以 `DSH_SNAPSHOT` 回放分支拉起 `dsh web` bin。** 已否决：它需要在交付的 CLI 中增加测试专用回放分支和环境变量管道。进程内 scaffold 已加载同一份 `apps/cli/cordis.yml`；只剩 argv、profile JSON 和 `AppCLIEntry` 胶水不在其覆盖范围内，而这些路径已由无密钥 CLI 冒烟覆盖。
+
+**为可测试性改 wire 协议。** 已否决：契约已有第一等的无密钥同构 seam（`InProcessApiClient(toFetchHandler(api))`），逐事件不合批的 SSE 恰是回放在浏览器中可观测的原因，测试一条不再交付的 wire 会颠倒该层的存在意义。
+
+**以真实模型浏览器测试充当无密钥车道。** 已否决：按构造即不确定；被调研的前车之鉴（open-webui）长出无界超时后被删除。带密钥的 W5 冒烟仍是真实模型侧的补充。
+
+**客户端 `data-dsh-busy` 安定信号。** 暂缓：两个场景下多条件安定轮询已经够用，host 侧 `whenIdle` 屏障承担了重活。重启条件：第一次安定轮询抖动，或某场景需要等待 DOM 不暴露的状态。
+
+## Testing
+
+车道自身：`pnpm run test:web` 与既有冒烟对一起无密钥运行两个场景；`DSH_SNAPSHOT=record pnpm exec vitest run --config vitest.web.config.ts apps/web/tests/<spec>` 对真实模型重录某场景的 fixture；`DSH_SNAPSHOT=refresh` 无密钥重写两份 aria 预期输出。`paceMs` 校验、节奏下限、节奏中中止、`assertConsumed` 的两种失败形态钉在 `packages/support/llm-replay/tests/llm-replay.spec.ts`。
+
+## 暂缓
+
+- **Web 头类别钉住**：web fixture 处处 token 化 `{{system}}`/`{{tools}}`，没有场景钉住 web 组合的提示词/工具 schema（`TODO(web-header-pin)`——scaffold 的 `recordFixture` JSDoc 有标记）。沿用 TUI 处处脱敏先例；当 web 组装的请求头与其镜像的 repl 组合进一步分叉时重审。
+- **CI 浏览器供给**：推翻 CI 无浏览器裁定，分阶段标准见上（`TODO(ci-browser)`）。
+- **恢复后追问场景**：真实 wire 上的历史/实时缝合路径；当该代码变更或回归时作为独立场景补充。
+
+## 后果
+
+Web 表面获得了录制一次/永久回放的层级：真实 chromium → SSE → apiproxy → 循环 → 工具 → 持久化的链路以约 10-30 秒无密钥运行，重复运行结果确定，fixture 由车道自身持有并可重录。接受的成本：每次有意的会话 UI 变更都以一次无密钥 `DSH_SNAPSHOT=refresh` 收尾（预期输出变动是受评审的 diff，锚断言保住语义绿色）；aria 格式归 Playwright 所有——仓库唯一不受自己控制的提交快照格式——因此 playwright 版本升级必须是刻意的升级加刷新提交（依赖在 `apps/web/package.json` 中浮动为 `^1.49.0`；若变动伤人则改为精确锁定）；回放的首次调用顺序绑定把每个场景限制为至多一个发起提示的会话，消费断言是绊线；`compact-basic` 与会话共享回放游标，仅在发布的 128k 目录窗口下保持闲置；在 CI 反转被单独决策之前，车道只在其运行之处（本地，`test:web`）把守回归。

+# Agent Note: Scriptable LLM wire fault server
+
+Status: implemented
+
+English | [中文](2026-07-25-scriptable-llm-wire-fault-server.zh.md)
+
+## Problem
+
+Adapter unit tests use local HTTP servers to classify individual provider failures, while retry tests use an in-process scripted `LlmAdapter` to prove closed-step recovery. Neither boundary provides a reusable server for running the shipping HTTP adapter, agent loop, and retry policy together, and neither lets a developer point an existing app at deterministic transport faults by changing only its base URL and API key.
+
+Connection refusal, a reset before the first event, clean EOF without `[DONE]`, a valid content-less completion, and a reset after partial output have different adapter and recovery outcomes. Treating them as one generic mock failure hides whether the provider boundary preserved the distinction and whether failed chunks remained outside committed model history.
+
+## Decision
+
+`@deepseek-ai/dsh-llm-mock-server` is a support package with an importable Node HTTP server and a standalone CLI. It accepts OpenAI-compatible root and `/v1` chat-completions paths, validates an optional bearer token, captures requests, and consumes one explicit behavior per accepted request. Script exhaustion fails loud; repetition requires `repeatLast`.
+
+Request behaviors cover socket reset, post-header disconnect, partial disconnect, stall, valid empty completion, clean truncated streams, malformed payloads, representative HTTP failures, complete text/reasoning/tool-call responses, slow streaming, and max-token completion. A true `connection_refused` is a CLI listener-lifecycle phase because a bound request handler cannot refuse its own TCP connection.
+
+The `random` script entry performs a new weighted selection for every request. The server exposes and logs its unsigned 32-bit seed, accepts caller-supplied relative weights, and ships a success-heavy stress profile that mixes transport, protocol, provider, timeout, and semantic-empty outcomes. The profile is configurable test pressure rather than an estimate of production incident frequency; `connection_refused` remains outside the request-level pool.
+
+The server reports wire facts only and does not classify retryability. Real-composition tests route it through `dsh-llm-deepseek`, `dsh-agent-loop`, and `dsh-llm-retry`: connection refusal, hard disconnect, partial reset, idle timeout, and a valid content-less completion recover under the existing default policy; clean partial EOF remains `STREAM_CLOSED` and is not retried by default. The package does not change those policies.
+
+## Verification
+
+Package tests exercise every request behavior, split UTF-8 request decoding, HTTP validation without script consumption, script exhaustion/repetition, stalled-connection teardown, CLI parsing and delay bounds, IPv6 base URLs, random seed reproducibility, weight validation, single-result telemetry, lifecycle cleanup, and the invariant companion under the per-file coverage gate. The retry integration suite proves exact request counts, numbered retry steps, request-body identity, failed partial-chunk isolation, semantic-empty recovery, clean-EOF classification, timeout recovery, true refused-connection recovery after delayed listener startup, and bounded exhaustion through the real HTTP/SSE adapter.
+
+## Alternatives considered
+
+**Implement the server in Python** — rejected because Node's standard HTTP and socket APIs expose every required fault, while TypeScript keeps the server, CLI parser, tests, package build, lint, and coverage inside the repository's existing toolchain. A second runtime would add environment and subprocess dependencies without increasing wire isolation.
+
+**Keep separate inline mock servers in adapter tests** — rejected because those fixtures cannot be launched by an existing app and would duplicate behavior sequencing, randomization, telemetry, and connection cleanup across suites. A support package gives tests a shared implementation without promoting it to product API.
+
+**Use only an in-process `LlmAdapter` mock** — rejected because it bypasses fetch, HTTP status/header parsing, SSE framing, socket termination, and the adapter idle watchdog: the exact boundaries this test infrastructure exists to exercise.
+
+**Change retry defaults with the server** — rejected because the server reveals existing semantics rather than deciding policy. Extending recovery to `STREAM_CLOSED` requires a separate decision with its own cost, latency, and duplicate-generation trade-offs.
+
+## Consequences
+
+Developers can reproduce fault sequences by changing only provider URL/key configuration, and automated tests can keep socket-level failures deterministic through explicit scripts and seeds. The same wire fixture now exposes gaps between hard resets, clean truncation, and recovered empty completions without splicing attempts or modifying model history.
+
+The server adds a support package, executable build entry, and behavior vocabulary that must remain compatible with both direct tests and CLI examples. Arrival-ordered scripts are intentionally shared across clients, random defaults are stress weights rather than operational truth, and exact connection refusal requires coordinating the client attempt with the pre-listen interval.

+# Agent Note: 可脚本控制的 LLM（大语言模型）协议层故障服务器
+
+Status: implemented
+
+[English](2026-07-25-scriptable-llm-wire-fault-server.md) | 中文
+
+## 问题
+
+适配器单元测试使用本地 HTTP 服务器对各类提供方故障逐一分类，重试测试则使用进程内的脚本化 `LlmAdapter` 证明已关闭步骤的恢复能力。这两个边界都无法提供可复用的服务器，以便同时运行交付版本的 HTTP 适配器、agent loop（智能体循环）和重试策略；开发者也无法仅修改现有应用的 base URL 与 API key，就让应用连接到确定性的传输故障。
+
+连接遭拒、首个事件前连接被重置、未收到 `[DONE]` 即正常 EOF、合法但无内容的完成，以及输出部分内容后连接被重置，会产生不同的适配器与恢复结果。把它们统一视为普通 mock 故障，会掩盖提供方边界是否保留了这些区别，以及失败请求的分片是否确实没有进入已提交的模型历史。
+
+## 决策
+
+`@deepseek-ai/dsh-llm-mock-server` 是一个支持包（package），提供可导入的 Node HTTP 服务器和独立 CLI（命令行界面）。它接受兼容 OpenAI 的根路径和 `/v1` chat-completions 路径，校验可选的 bearer token，捕获请求，并对每个已接受请求消耗一个显式行为。脚本耗尽时快速失败；只有设置 `repeatLast` 才会重复最后一个行为。
+
+请求行为覆盖 socket 重置、发送 header 后断开、发送部分内容后断开、停滞、合法空完成、正常关闭但被截断的流、畸形 payload、典型 HTTP 故障、完整的文本/推理/工具调用响应、慢速流式输出以及达到 token 上限的完成。真正的 `connection_refused` 由 CLI 的监听器生命周期阶段实现，因为已经绑定端口的请求处理器无法拒绝自身的 TCP 连接。
+
+脚本项 `random` 会为每个请求重新执行一次加权选择。服务器公开并记录其无符号 32 位 seed，允许调用方提供相对权重，并内置一套偏重成功结果的压力测试配置，将传输、协议、提供方、超时和语义空结果混合在一起。该配置用于提供可调的测试压力，并非对生产事故发生频率的估算；`connection_refused` 仍不进入请求级随机池。
+
+服务器只报告协议层事实，不判断是否可重试。真实组合测试让请求依次经过 `dsh-llm-deepseek`、`dsh-agent-loop` 和 `dsh-llm-retry`：在现有默认策略下，连接遭拒、硬断开、部分输出后重置、空闲超时以及合法的无内容完成均可恢复；正常关闭的部分输出 EOF 仍归类为 `STREAM_CLOSED`，默认不重试。该包不会改变这些策略。
+
+## 验证
+
+包测试覆盖所有请求行为、跨分片 UTF-8 请求解码、不消耗脚本的 HTTP 校验、脚本耗尽与重复、停滞连接清理、CLI 解析及延迟边界、IPv6 base URL、随机 seed 可复现性、权重校验、单结果遥测、生命周期清理，以及逐文件覆盖率门禁下的配套不变式插件。重试集成套件通过真实 HTTP/SSE（Server-Sent Events）适配器，验证准确的请求次数、带编号的重试步骤、请求体完全一致、失败的部分分片不会泄漏、语义空结果恢复、正常 EOF 分类、超时恢复、监听器延迟启动后从真实连接遭拒中恢复，以及有界重试耗尽。
+
+## 曾考虑的替代方案
+
+**使用 Python 实现服务器**：不予采纳。Node 的标准 HTTP 与 socket API 足以暴露所有所需故障，而 TypeScript 可以让服务器、CLI 解析器、测试、包构建、lint 和覆盖率全部留在仓库现有工具链中。引入第二套运行时会增加环境与子进程依赖，却不能增强协议隔离。
+
+**在适配器测试中继续使用各自独立的内联 mock 服务器**：不予采纳。这些 fixture（测试前置数据）无法作为独立服务器启动并供现有应用连接，还会让不同测试套件重复实现行为编排、随机化、遥测和连接清理。支持包让测试共享同一套实现，又不会将其提升为产品 API。
+
+**仅使用进程内的 `LlmAdapter` mock**：不予采纳。它会绕过 fetch、HTTP 状态与 header 解析、SSE 分帧、socket 终止以及适配器的空闲看门狗，而这正是这套测试基础设施要覆盖的边界。
+
+**随服务器一起修改默认重试策略**：不予采纳。服务器用于揭示既有语义，而非决定策略。是否将恢复能力扩展到 `STREAM_CLOSED`，需要单独决策，并权衡成本、延迟和重复生成风险。
+
+## 后果
+
+开发者只需修改提供方 URL/key 配置即可复现故障序列；自动化测试则可通过显式脚本和 seed，让 socket 层故障保持确定性。同一套协议 fixture 现在可以暴露硬重置、正常截断与恢复后的空完成之间的差异，而不会拼接多次尝试的内容或修改模型历史。
+
+服务器新增了一个支持包、可执行构建入口和行为词汇，三者必须同时兼容直接测试与 CLI 示例。按请求到达顺序执行的脚本有意由所有客户端共享；随机模式的默认值代表压力测试权重，而非实际运行规律；精确模拟连接遭拒时，需要让客户端尝试与监听开始前的时间区间协调一致。

The harness models its core vocabulary — content blocks, message sources, finish reasons, turn triggers, turn-end reasons, and session events — as **merge-extensible maps**: a TypeScript `interface` (e.g. `SessionEventMap`, `ContentBlockMap`) that plugins augment via declaration merging, with the public union derived as `Map[keyof Map]`. This is the repo's universal extension pattern, documented in [docs/architecture.md](../../../../docs/architecture.md) ("The same merge-extensible-map pattern is used for `MessageSource`, `FinishReason`, `TurnTrigger`, and `TurnEndReason`") and relied on by the `defineTool` `InferArgs` DSL and the `assertNever` exhaustiveness convention.

+# Agent Note: 事件词汇的运行时 schema（Zod 与 merge-extensible-map 模式之辩）
+
+Status: proposed
+
+[English](2026-06-16-typed-event-schemas.md) | 中文
+
+## 问题
+
+harness 将其核心词汇——内容块、消息来源、结束原因、轮次触发器、轮次结束原因与会话事件——建模为 **merge-extensible map**：一个 TypeScript `interface`（如 `SessionEventMap`、`ContentBlockMap`），插件通过声明合并对其扩展，公开联合类型则以 `Map[keyof Map]` 派生。这是本仓库的通用扩展模式，记录在 [docs/architecture.md](../../../../docs/architecture.md) 中（「The same merge-extensible-map pattern is used for `MessageSource`, `FinishReason`, `TurnTrigger`, and `TurnEndReason`」），`defineTool` 的 `InferArgs` DSL 和 `assertNever` 穷举约定都依赖于它。
+
+该模式**仅存在于编译期**。类型在运行时消失：没有 schema 对象可供校验传入值、解析不可信输入或在运行时枚举变体。[会话持久化契约](../../implemented/architecture/2026-06-14-session-persistence.md)暴露了两个后果：
+
+1. **持久化将 `event.data` 视为不透明 JSON。** JSONL/SQLite 后端对每个事件逐字 `JSON.stringify`/`JSON.parse`；唯一的运行时守卫是 `isJsonValue`（往返可序列化性检查：拒绝 BigInt、函数、循环引用、非有限数等），而非结构校验。一个损坏但仍为合法 JSON 的事件数据（字段类型错误、字段缺失）会静默往返，只有在后续消费方的 `switch` 中才可能被捕获。
+2. **插件新增变体没有运行时契约。** 一个通过声明合并添加新 `SessionEventMap` 键的插件，在自身代码中获得了编译期类型，但没有任何机制校验它产出的值是否符合它所声明的形状——无论是在生产者处、持久化边界处还是重新加载时。
+
+由此引出问题：事件词汇是否应迁移到 **Zod** 或其他运行时 schema 库，使持久化和插件边界拥有运行时 schema 而非被擦除的类型。
+
+本 Agent Note（agent 决策记录）界定该问题的范围，不提出具体实现。
+
+## 为什么这不是一个持久化层的改动
+
+很容易把「用 Zod 做序列化」理解为对 `dsh-session-persistence-jsonl/src/format.ts` 的局部修改。但它不是，原因在于一个结构性事实：**插件无法对 Zod schema 进行声明合并。** 声明合并是 TypeScript 编译期机制；Zod schema 是运行时值。要用 Zod 校验事件，就需要一个**运行时注册表**，每个产出事件的包（package）向其贡献自己的 schema（如 `ctx.sessionEvents.register('compaction/marker', z.object({…}))`），每个消费方从中读取。这个注册表——而非持久化后端——将成为词汇的真源，取代 merge-extensible 接口。
+
+因此，真正的提案是：**用运行时 schema 注册表替换编译期的 merge-extensible-map 模式，范围覆盖整个仓库。** 这是一次核心词汇的重新设计。
+
+## 影响范围（已度量）
+
+将事件/词汇表面迁移到运行时 schema，至少涉及：
+
+- **六个 merge-extensible map**（约 370 行核心类型）：`ContentBlockMap`、`MessageSourceMap`、`FinishReasonMap`（位于 `dsh-llm`）；`TurnTriggerMap`、`TurnEndReasonMap`、`SessionEventMap`（位于 `dsh-session`）。
+- **约 10 处 `declare module` 扩展点**，分布在 `dsh-agent`、`dsh-agent-loop`、`dsh-bash`、`dsh-llm`、`dsh-session`、`dsh-session-persistence`、`dsh-system-prompt`、`dsh-tools` 各包中——每处都将从声明合并改为运行时 `register()` 调用。
+- **事件生产者**——agent loop（智能体循环）中 16 处 `session.append(...)` 调用——形状不变，但现在在边界处被校验。
+- **约 7 个 switch 消费方**，对这些联合类型进行分支：`deriveMessages` 与包自有的不变式 companion（`dsh-session`）、`BlockAssembler`（`dsh-llm`）、两个 LLM（大语言模型）适配器（`dsh-llm-deepseek`、`dsh-llm-pi-ai`）以及工具 schema 层（`dsh-tools`）。`assertNever` 对封闭联合类型的穷举 vs 对可扩展联合类型的 fall-through 约定（一条已记录的 lint 规则）需要重新考量——运行时变体在静态层面不可穷举。
+- **`defineTool` 的 `InferArgs` DSL**（`dsh-tools`），它从编译期 schema 规范派生出零类型转换的 `execute` 参数类型——这是当前方案的标杆用例。
+- **文档**：architecture.md（该模式被描述为基础性的）、[开发模式不变式](../../implemented/architecture/2026-06-11-dev-invariants-over-deep-readonly.md)，以及所有引用该模式的 Agent Note。
+
+这是一次仓库级别的词汇重新设计，而非持久化的实现细节。
+
+## 曾考虑的替代方案
+
+### A. 维持现状——merge-extensible 类型 + 持久化边界处 `isJsonValue`
+保留编译期模式。持久化继续使用不透明 JSON + 可序列化性守卫。插件通过声明合并扩展；事件*形状*的正确性由生产者负责，并由 TypeScript 在编译期保证。启用包自有的不变式 companion 后，它们会检查选定的跨记录关系，但不提供通用运行时形状 schema。
+
+- **优点**：零变动；插件扩展只需一行 `interface` 增补，享有完整类型推断，无需运行时注册仪式；无新运行时依赖；`defineTool` DSL 与 `assertNever` 穷举继续工作。
+- **缺点**：持久化边界和插件 seam 处无运行时结构校验；格式错误但仍为合法 JSON 的数据被延迟捕获。
+
+### B. 仅对头部/封闭形状做校验（schemastery），事件仍为不透明
+仅对那些已有手写类型守卫的真正封闭形状加以收紧——例如 JSONL 的 `HeaderLine` 守卫（`isHeaderLine`）——使用 **schemastery**（仓库现有的 schema 库，已用于每个插件的 `static Config`）。merge-extensible 事件联合类型保持不变。
+
+- **优点**：改动小，契合现有约定（schemastery，而非新库）；用声明式 schema 替换封闭形状上的手写守卫；无核心重新设计。
+- **缺点**：不解决事件数据校验问题；仅固定的元数据记录得到改善。
+
+### C. 为整个词汇建立运行时 schema 注册表（Zod 或 schemastery）
+用运行时注册表替换 merge-extensible map，生产者向其贡献 schema，持久化/消费路径据此校验。
+
+- **优点**：持久化边界和插件 seam 处获得真正的运行时校验；单一真源；可支撑通用工具（自动生成文档、模糊测试、协议格式检查）。
+- **缺点**：上述全部影响范围；**Zod 目前不是直接依赖**（仅作为 `@earendil-works/pi-ai` 的传递依赖），仓库选定的 schema 库是 **schemastery**——广泛引入 Zod 本身就是一个依赖决策；声明合并的易用性（一行插件扩展、完整推断）被运行时注册 + 手动类型接线取代；`assertNever` 穷举保证弱化（运行时变体在静态层面不可穷举）。
+
+## 提案
+
+推迟。如果需要在持久化边界做运行时校验，**方案 B**（对封闭的头部和元数据形状使用 schemastery）是现有约定下的适度步骤。**方案 C** 是一个架构决策，需要自己的实现 Agent Note，其中包括 Zod 与 schemastery 之间的选择。
+
+## 验收标准
+
+- 方案 C 只能通过自己的实现 Agent Note 推进，绝不能作为持久化的附带改动。
+- 如果采纳方案 B，封闭的头部/元数据形状（JSONL 的 `isHeaderLine` 守卫及同类）改用 schemastery 校验，替代手写守卫，merge-extensible map 保持不动。
+
+## 风险
+
+- 推迟意味着事件 `data` 在持久化边界处仍无结构校验：格式错误但仍为合法 JSON 的数据被延迟捕获，由消费方的 `switch` 兜底——这是现状的代价，有意接受。
+- 如果方案 C 最终被采纳，易用性的损失是真实的：一行声明合并变为运行时注册加手动类型接线，`assertNever` 的静态穷举保证弱化。
+
+## 待解问题
+
+- 如果采用注册表，库选 **schemastery**（已在仓库中，已作为配置 schema 库）还是 **Zod**（生态更丰富，目前仅为传递依赖）？同时维护两个 schema 库本身就是一种成本。
+- 能否采用混合方案：保留编译期推断（使 `defineTool` 和插件开发体验不受影响），同时为每个变体添加*可选*的运行时 schema，仅在持久化/协议边界校验，而非每次进程内 append 都校验？
+- `ctx.invariants` 服务启用后是否已覆盖了足够多的运行时形状缺口，使得边界校验仅在面对真正不可信输入（重新加载外部修改过的日志）时才有必要？

+# Agent Note: Domain KV storage capability seam and the workspace entity
+
+Status: proposed
+
+English | [中文](2026-07-24-domain-kv-storage-and-workspace.zh.md)
+
+## Problem
+
+The host's only persistence surface is the session event log (`packages/session-persistence`: append-only, one file per session). Anything that does not belong to a single session has nowhere to live, and two real needs exist today:
+
+- **The workspace entity.** The GUI needs workspace as a real object: path, title, and the list of owned sessions. Ownership belongs to the workspace — "which sessions belong to this workspace" is not any single session's fact, so writing it into the session log is semantically wrong. Until now workspace was only a sidebar visual grouping derived from cwd, with no entity (that conclusion has been overturned).
+- **Dynamic session metadata** (the foreseeable second consumer). Cold session listings read only the first log line (an immutable creation-time snapshot); title, terminal status, and anything that evolves with the session is unavailable. The fix direction is a sidecar metadata table — exactly a KV table with high-frequency per-key updates.
+
+Separately, workspace deletion will eventually need to delete its owned sessions, and `SessionPersistence` has no delete primitive nor does the host expose a `session.delete` endpoint — that gap's design is settled in this note, but its implementation is marked future work: this phase touches no session-side code.
+
+## Proposal
+
+Create the `packages/storage/` group — the `ctx.storage` hub (backend registry + data-form mounts), two backends, the domain data form — plus the workspace consumer package; extend `SessionPersistence` with a delete primitive.
+
+| Package | Path | ctx surface | This phase |
+| --- | --- | --- | --- |
+| `@deepseek-ai/dsh-storage` | `packages/storage/storage/` | `ctx.storage` (the hub) | ✓ |
+| `@deepseek-ai/dsh-storage-json` | `packages/storage/storage-json/` | registers backend `json` | ✓ |
+| `@deepseek-ai/dsh-storage-sqlite` | `packages/storage/storage-sqlite/` | registers backend `sqlite` | ✓ |
+| `@deepseek-ai/dsh-storage-domain` | `packages/storage/storage-domain/` | mounts `ctx.storage.domain` | ✓ |
+| `@deepseek-ai/dsh-workspace` | `packages/workspace/workspace/` | `ctx.workspace` | ✓ |
+| `SessionPersistence.delete` extension + cascade orchestration | `packages/session-persistence/*` | new method on the existing seam | ✗ future work (session side untouched this phase) |
+| `workspace.*` / `session.delete` RPC, GUI wiring, boot assembly | — | — | ✗ next phase |
+
+(workspace lives in its own group rather than `packages/host/`: the host group's naming rule requires the `dsh-host-*` prefix while this package is named `dsh-workspace`; and the workspace entity is a domain concept, not bound to the host assembly tier. Unrelated to the existing `workspace-context` package — that is an AGENTS.md instruction loader.)
+
+Dependency direction: `dsh-workspace` → `dsh-domain` → `dsh-storage` ← the two backends. `dsh-workspace` additionally depends on the read-only face of `ctx.sessionPersistence` (attach's cwd check reads the session header; when the service is absent, attach rejects outright — no verification, no bookkeeping). The `ctx.sessions` running-check for session deletion moves into future work together with the cascade.
+
+### `dsh-storage`: the storage hub
+
+A pure registration hub, no IO of its own, no Config. The `Storage` service mounts at `ctx.storage` with two faces: `backend` (a `BackendRegistry`: `register(name, backend)` returns the disposer, duplicate names throw; `get(name)` throws `backend-not-found` for unknown names) and data-form mounting (`mount(form, facility)` over the merge-extensible `StorageForms` map, into which `dsh-domain` merges the `domain` key; unmounted access throws `form-not-mounted`). The signature text lives in `packages/storage/storage/src/index.ts` and `src/registry.ts`.
+
+**Multiple backends stay mounted side by side**; which backend serves a domain is `dsh-domain`'s configuration (below), never a global either-or. Disposer semantics = remove the name from the table; closing the backend itself belongs to the backend package's effect closure, unregister first then close.
+
+A backend is one **medium owner** (a file-tree root / one db file) exposing primitives through **data-shape facets** — only `kv` this phase; the session migration adds `log` (see the migration section). A facet is an optional member: absence means the backend cannot serve that shape, and resolution fails loud. The `kv` facet's primitive surface: `open(descriptor)` (descriptor = name/version/table list/global flag, with names and table names restricted to `^[a-z][a-z0-9_]*$` doubling as file-name and SQL-identifier segments) returns a unit exposing `loadAll` / `putRecord` / `deleteRecord` (missing key is a no-op) / `setGlobal` / `close` (idempotent); values are opaque JSON to the backend. The normative text (with per-method JSDoc) is `packages/storage/storage/src/backend.ts`.
+
+The backend contract (asserted clause by clause by the shared conformance suite, one suite for both backends):
+
+1. `open` creates when the medium holds nothing (lazy materialization allowed: may defer to the first write, but `loadAll` must immediately serve empty tables); loads when the medium exists.
+2. A stored version ≠ descriptor.version → `StorageError('version-mismatch')`; no migration, no rebuild.
+3. Durability: after a write primitive resolves, a process crash followed by a re-open must observe the write in `loadAll`.
+4. The backend does not promise write ordering within a unit — **the caller serializes**; the backend only guarantees each single call is atomic (JSON whole-file replace / SQLite single statement).
+5. `deleteRecord` is idempotent; `putRecord` overwrites.
+6. Any string key / any JSON value is safe (keys never reach file paths, a structural property).
+7. `close` is idempotent; any operation after close → `StorageError('closed')`.
+
+The error vocabulary is `StorageError` with a code discriminant: `backend-not-found` / `form-not-mounted` / `duplicate-backend` / `duplicate-mount` / `version-mismatch` / `malformed-medium` / `closed` (`packages/storage/storage/src/error.ts`).
+
+### `dsh-storage-json`
+
+Config is `root` only (required, no default, schemastery); apply registers backend `json` inside `ctx.effect()`, and the disposer unregisters the name before `backend.close()`.
+
+- Layout `<root>/<unitName>.json`, one file per unit; directory 0o700, files 0o600.
+- File format (version stamp in the header; the file is always the current net state, `JSON.stringify(…, null, 2)` human-readable — that legibility is this backend's reason to exist):
+
+```json
+{
+ "unit": { "name": "workspace", "version": 1 },
+ "global": null,
+ "tables": { "workspaces": { "<key>": {} } }
+}
+```
+
+- Writes: every write primitive = full serialization of the in-memory state → temp write + fsync → atomic rename publish (the Windows variant follows session-persistence-jsonl's win32 path). Memory is authoritative, disk is its projection.
+- `loadAll`: parse the whole file at open; a missing `unit` header, non-object tables, etc. → `malformed-medium`. A missing file = an empty unit, materialized on first write.
+
+### `dsh-storage-sqlite`
+
+Config is `path` (required, `':memory:'` allowed) plus `journalMode` (enum, default `wal`); apply mirrors json, registering backend `sqlite`.
+
+- `node:sqlite` `DatabaseSync`; the open sequence follows session-persistence-sqlite: mkdir 0o700 → `open(path,'wx',0o600)` exclusive create when missing → `PRAGMA foreign_keys=ON` → journal_mode → version check → create tables.
+- Physical layout version `STORAGE_SQLITE_SCHEMA_VERSION = 1` in `PRAGMA user_version`: 0 → stamp; ≠ → `version-mismatch`.
+- DDL (all STRICT; table names concatenated from the restricted character set with the `u_` prefix, no external input ever reaches DDL):
+
+```sql
+CREATE TABLE IF NOT EXISTS units (name TEXT PRIMARY KEY, version INTEGER NOT NULL) STRICT;
+CREATE TABLE IF NOT EXISTS unit_globals (
+ unit TEXT PRIMARY KEY REFERENCES units(name), value TEXT NOT NULL) STRICT;
+-- 每 unit 每表：
+CREATE TABLE IF NOT EXISTS "u_<unit>_<table>" (
+ key TEXT PRIMARY KEY, value TEXT NOT NULL) STRICT; -- value = 记录 JSON 文档
+```
+
+- Unit versions live in `units` rows; a descriptor mismatch → `version-mismatch`. Row granularity is document-per-row, preserving precise per-key durable updates (the path left open for high-frequency point-update tables like the session sidecar); when query needs appear, JSON1 reads the value column directly.
+- Write primitives are single statements and thus atomic; no cross-statement transactions needed (the domain layer has no cross-table transactions, see the out-of-scope list).
+
+### `dsh-domain`: the domain data form
+
+A single implementation, not abstracted; consumers depend on this layer only and never touch backends directly.
+
+```ts ignore-check
+export const Config = z.object({
+ backend: z.string().required(), // 默认后端名，必填
+ routes: z.dict(z.string()).default({}), // per-domain 覆盖：{ workspace: 'sqlite' }
+})
+
+export function apply(ctx: Context, config: Config) {
+ ctx.effect(() => ctx.storage.mount('domain', new DomainFacility(ctx, config)))
+}
+```
+
+(Facility unmount order: dispose each domain first (drain its write chain), then remove the name from the hub — in-flight writes still emit `domain/changed` during the drain, and the event-consistency invariant resolves domains back through the facility, so the name must stay resolvable at that point.)
+
+Domain declarations (the spec object is defined and exported by the package that owns the domain — the single source of type and runtime truth; schemas use zod with `z.infer` deriving the types without re-declaration — the record model projects into RPC wire schemas next phase and the wire boundary is all zod; schemastery still owns plugin Config only):
+
+```ts ignore-check
+export interface DomainGlobalSpec<G> { readonly schema: ZodType<G>; readonly initial: G }
+export interface DomainTableSpec<K extends string, V> { readonly valueSchema: ZodType<V> }
+
+export interface DomainSpec {
+ readonly name: string // ^[a-z][a-z0-9_]*$
+ readonly version: number
+ readonly global?: DomainGlobalSpec<unknown>
+ readonly tables: Record<string, DomainTableSpec<string, unknown>>
+}
+
+export function defineDomain<S extends DomainSpec>(spec: S): S
+export function domainTable<K extends string, V>(schema: ZodType<V>): DomainTableSpec<K, V>
+```
+
+`DomainFacility.open(spec)` exact semantics (sequential; any failing step fails the whole open):
+
+1. A domain with this name already open → `DomainError('already-open')`.
+2. Backend name = `config.routes[spec.name] ?? config.backend`; `ctx.storage.backend.get(name)` (an unmounted name propagates `backend-not-found` — misconfiguration fails loud).
+3. Backend lacks the `kv` facet → `DomainError('facet-unsupported')`.
+4. `kv.open(descriptorOf(spec))` (the descriptor is a direct projection of the spec).
+5. `loadAll()`; every record passes `valueSchema.parse`, the global passes its schema (null takes `initial`, not persisted — first write materializes). A failure → `DomainError('invalid-record', { table, key })` (the durable boundary must validate; the write side does not re-validate).
+6. Construct the `Domain` and register `ctx.effect()`: the disposer drains the write chain → `unit.close()`.
+
+```ts ignore-check
+export interface Domain</* 由 spec 推导 */> {
+ readonly name: string
+ readonly global: { get(): G; set(value: G): Promise<void> } // 仅当 spec.global 声明
+ table<N extends keyof S['tables']>(name: N): KvTable<KeyOf<N>, ValueOf<N>>
+}
+
+export interface KvTable<K extends string, V> {
+ get(key: K): V | undefined // 内存快照，同步
+ entries(): IterableIterator<[K, V]>
+ keys(): IterableIterator<K>
+ readonly size: number
+ put(key: K, value: V): Promise<void>
+ delete(key: K): Promise<boolean> // false = 本就不存在
+ /** Atomic read-modify-write on the domain's single write chain; fn is sync-pure. */
+ update(key: K, fn: (current: V) => V): Promise<V> // 缺 key → DomainError('missing-key')
+}
+```
+
+Rules:
+
+- **Single-level mapping**: key → record, no nested tables; hierarchical needs use composite keys or fields inside the value. The two backends stay isomorphic as a result (one JSON object level ↔ one SQLite row).
+- **Records are plain data**: immutable, directly JSON-serializable POJOs; values returned by `get`/`entries` must not be mutated in place (TypeScript readonly projection, no runtime freezing). Behavior-carrying domain objects belong to consumer packages.
+- **Serialized writes**: one promise chain per domain; `put`/`delete`/`update`/`global.set` all queue on it; `update`'s fn runs on the chain, so concurrency cannot interleave. No active-record (pulling out a mutable object that auto-persists — uncontrollable persist timing, in conflict with the whole-unit atomic-rewrite model).
+- **Version fails loud**: a stored version differing from the spec throws outright; no migration, no rebuild (the data is not regenerable; pre-release rejects old formats).
+- **Change events**: after each write's durability resolves, emit `domain/changed` (`@mode emit`), one per record, no old value (matching the repository's "new snapshot + operation discriminant" convention, template `goal/changed`); the payload `DomainChanged` is a put/deleted discriminated union — domain + table + key (both `''` for global changes) + operation, with the put branch carrying the new snapshot value and the deleted branch carrying none (`packages/storage/storage-domain/src/events.ts`). This is next phase's RPC push-frame event source. The error vocabulary is `DomainError`, codes: `already-open` / `facet-unsupported` / `invalid-record` (with `{ table, key }`) / `missing-key` / `closed`.
+
+### Future work: session-side deletion (design settled, not implemented this phase)
+
+This section is the settled construction spec; the implementation phase changes code only, not semantics. No session-persistence file is modified this phase.
+
+```ts ignore-check
+export abstract class SessionPersistence extends Service {
+ /**
+ * Permanently delete one session's stored log.
+ * Queued on the per-id write chain (serialized with in-flight appends).
+ * Unknown id → reject; un-materialized create intent → cancel it and resolve.
+ * After deletion the id behaves as unknown for every subsequent operation.
+ */
+ abstract delete(id: SessionId): Promise<void>
+}
+```
+
+- JSONL backend: unlink the session's file (including the `.zstd` variant); neither file nor intent → reject.
+- SQLite backend: one transaction `DELETE FROM events…; DELETE FROM sessions…`; zero rows hit and no intent → reject.
+- After a successful delete, emit `'session-persistence/deleted'(id: SessionId)` (`@mode emit`; the session-persistence event surface, unrelated to `domain/changed`). Derived data (the session-query full-text index and the like) subscribes and cleans itself; the persistence layer never reaches into indexes, and the crash window is covered by derived indexes being droppable-and-rebuildable.
+
+Orchestration rules (implemented together with the cascade; the `session.delete` RPC and the workspace cascade reuse the same rules):
+
+| Check (in order) | On failure |
+| --- | --- |
+| No target (the whole subtree when recursive) is running in `ctx.sessions` | throw, delete nothing; callers cancel first then delete — the persistence layer never reaches back into the runtime |
+| Non-recursive: the target has no descendants (descendants = the `parentSessionId` transitive closure, derived from `list()` headers) | throw: by default only leaves are deletable; `recursive: true` opts into recursion |
+| Recursive order is bottom-up (leaves → root) | — a mid-way crash leaves only "half the subtree deleted, ancestors intact"; re-running the same delete converges, and no dangling parent exists at any moment |
+| Some id in the cascade is already gone from disk | skip (idempotent resumption); any other error aborts |
+
+### `dsh-workspace`
+
+The package owns the `WorkspaceId` brand and exposes `ctx.workspace`. The record key is a generated uuid — path is not the key: normalization rewrites it, and reference anchors must be stable.
+
+```ts ignore-check
+export type WorkspaceId = Branded<'WorkspaceId'>
+export function WorkspaceId(id: string): WorkspaceId
+
+const workspaceRecord = z.object({
+ path: z.string(), // realpath，见下
+ title: z.string(),
+ sessionIds: z.array(z.string().transform(SessionId)),
+ createdAt: z.string(), // ISO
+ updatedAt: z.string(),
+})
+export type WorkspaceRecord = z.infer<typeof workspaceRecord>
+
+export const workspaceDomainSpec = defineDomain({
+ name: 'workspace', version: 1,
+ tables: { workspaces: domainTable<WorkspaceId, WorkspaceRecord>(workspaceRecord) },
+})
+
+declare module 'cordis' { interface Context { workspace: WorkspaceRegistry } }
+
+export interface Workspace {
+ readonly id: WorkspaceId
+ readonly path: string
+ readonly title: string
+ readonly sessionIds: readonly SessionId[] // 唯一真相且有序：数组序即展示序
+ setTitle(title: string): Promise<void>
+ /** Record a session under this workspace (idempotent). Rejects when the session
+ * header's cwd (realpath) differs from this workspace's path. */

+}
+
+export class WorkspaceRegistry extends Service {
+ constructor(ctx: Context) // super(ctx, 'workspace')
+ // start(): this.domain = await ctx.storage.domain.open(workspaceDomainSpec)
+ // 实体缓存 Map<WorkspaceId, WorkspaceEntity> 重建
+ create(path: string, title?: string): Promise<Workspace> // realpath 后撞已有 → reject
+ get(id: WorkspaceId): Workspace | undefined
+ list(): Workspace[]
+ resolveByPath(path: string): Promise<Workspace | undefined> // 同 realpath 口径，故 async
+ // delete：future work（与 session 级联删一起做，见下）；本期不提供任何删除入口
+}
+```
+
+- **Path canon**: the stored value = `fs.realpath(input)` (trailing slashes, `..`, and symlinks all resolved); uniqueness = string equality after normalization (a symlink resolving to the same directory counts as a collision). A missing directory makes create reject outright (realpath fails — a workspace must point at an existing directory; "Create new = make the directory" is upper-layer interaction: mkdir first, then create). The session cwd in attach checks follows the same canon. Single-valued cwd + unique path ⇒ one session structurally belongs to at most one workspace; double bookkeeping is impossible on the write side.
+- **Title**: a display name, defaults to `basename(path)`, mutable, duplicates allowed. Ownership is never derived from cwd as a fallback — cwd cannot express ordering, and ownership is a workspace-side fact; sessions started headless belong to no workspace.
+- Consumers see only the `Workspace` interface; `WorkspaceEntity` stays inside the package (a single implementation does not pre-split a seam). Entities are unique per id (registry cache); the record snapshot is swapped in place after each write, and the outside sees getters only. Every write funnels through the entity's internal `mutate(fn)` → `table.update`, with `updatedAt` refreshed inside mutate. Domain objects never cross RPC; next phase the wire layer projects records into zod wire schemas.
+- **Workspace deletion is future work as a whole** (settled 2026-07-24): the registry ships no delete method this phase — the half-measure "delete the record, keep the sessions" is not exposed; deletion and the session cascade (`recursive` parameter, running checks, bottom-up order, crash-rerun convergence) land as one complete semantic together with the session delete primitive; the order then is delete sessions one by one → prune the ledger → delete the workspace record.
+
+Consistency doctrine (the ledger = the only ownership authority; the implementation and test baseline):
+
+| Situation | Behavior |
+| --- | --- |
+| A ledger id has no session on disk | filtered at `list()`/entity projection; pruned by the next mutate; no error (a normal product of deletion crash-consistency) |
+| A session's cwd matches a workspace but is not in the ledger | not owned: no merging, no adoption. The GUI may later build an "orphan sessions" area (orphans = the complement of all ledgers) |
+| One session in two ledgers | structurally blocked on the write side (attach check); detected at load → throw (externally hand-edited data, never masked) |
+| The workspace directory does not exist | record and ledger stay; `status()` = `'missing-dir'`; the storage layer never auto-deletes (the directory may only be temporarily moved) |
+
+### Reuse and the session-backend migration outlook
+
+**Long-term direction**: the pure medium operations inside session-persistence's JSONL/SQLite backends sink into `dsh-storage` backends (the session packages stay; the `SessionPersistence` seam and coordinator semantics do not move — only the file/db operation layer beneath them does). The motive for reuse: the medium layer is all filesystem operations, database calls, and cross-platform grit (Windows permission and atomic-publish variants, fsync semantics, exclusive file creation…), which should be written once; business semantics (how a session appends, when, and what) stay above — while "did this append complete correctly underneath" (durability/atomicity/platform correctness) is the lower layer's responsibility, and the responsibility boundary is the facet primitive contract. The backend interface is therefore designed as **medium owner + data-shape facets**: a session log is an append-only stream, a different shape from KV — forcing them into one set of primitives would deform both, so facets split them (`kv` this phase, `log` at migration) while sharing the medium and its lifecycle.
+
+The current reuse audit (an account already legible before the migration):
+
+| Existing session-persistence logic | Nature | Disposition |
+| --- | --- | --- |
+| JSONL: temp write + fsync + link/unlink atomic publish, 0o700/0o600 permissions, Windows variant (win32.ts) | pure medium | copied by `dsh-storage-json` this phase (whole-file atomic rewrite is the same protocol); becomes the shared implementation at migration |
+| JSONL: line-append, first-line header fast read, zstd per-frame compression | log shape | stays put; moves into the `log` facet at migration |
+| SQLite: openDatabase (mkdir/exclusive create/PRAGMA sequence/user_version check) | pure medium | copied by `dsh-storage-sqlite` this phase — the two openDatabase copies are already near line-identical and this group is the third user; copy now, extract at migration |
+| SQLite: events/sessions schema, same-transaction materialization | log shape | stays put; moves into the `log` facet at migration |
+| coordinator (per-id write chain, lazy materialization, crash repair, flush barrier) | session semantics | never sinks — event-log domain logic whose counterpart here is the domain layer's write chain; each owns its own |
+| encodeSegment (id-to-path escaping) | medium utility | unused on the domain side (keys never reach paths); sinks together with the `log` facet (one file per session) at migration |
+
+**This phase does not touch session-persistence's medium code** (only the delete primitive is added); the table above is the migration-phase work list and the design evidence that the backend interface must accommodate the log shape.
+
+### Test matrix
+
+| Suite | Coverage | Backends |
+| --- | --- | --- |
+| backend contract (shared suite, written once, run on both) | the seven contract clauses + version rejection + close idempotence | json, sqlite (`:memory:` + temp dirs) |
+| registry/mount | duplicate registration, unmounted access, disposer removal | — |
+| domain layer | the six open steps, schema rejection, update serialization (concurrent interleaving stress), `domain/changed` per record, global initial-value lazy materialization, routing and `facet-unsupported` | either (json) |
+| workspace | create/uniqueness/realpath, attach checks (including rejection when sessionPersistence is absent), the four consistency-doctrine cases | mock domain or json |
+| session delete contract (future work, joins runPersistenceContract at implementation) | unknown id, deleted-id reuse, un-materialized intent, serialization with in-flight appends, the deleted event | jsonl, sqlite |
+
+Snapshots: no model-visible or assembly surface this phase, none added; next phase's RPC wiring brings them with the `workspace.*` domain.
+
+### Out-of-scope list
+
+| Not doing | Trigger | Rework point | Groundwork |
+| --- | --- | --- | --- |
+| The full deletion suite (`SessionPersistence.delete`, the deleted event, `registry.delete` cascade, recursive delete, running checks) | future work starts (before the GUI needs delete interactions) | implement per the future-work section above: the session primitive + `registry.delete(id, { recursive? })` land as one | orchestration rules and rejection table settled in this note; no deletion entry exists this phase, so no half-semantics to stay compatible with |
+| The `log` facet and the session-backend migration | any phase after this one | sink the medium operations (the reuse audit table is the work list) | the facet structure is in place; both backends' medium code is organized in sinkable shape already |
+| Multi-process write protection | two host processes writing one medium | JSON backend file locks; SQLite WAL is natively multi-process | all writes already funnel through the domain's single point; locking touches backends only |
+| Cross-process change observation | GUI reconnect awareness | the revision pattern (copy session-persistence) | `domain/changed` already exists in-process |
+| Data migration | model changes after the first tagged release | version-driven per-domain migration | versions are on the medium from day one |
+| Large-table performance | a thousand-record domain routed to json | point `routes` at sqlite, migrate the data by hand once | routing is configuration; consumers unchanged |
+| Multi-segment keys | a real two-segment consumer appears (per-workspace per-session dimension data) | key generics become tuples, SQLite composite primary keys, JSON nested levels | single-level tables are the one-segment special case; no arbitrary-depth nesting; no string-concatenated keys |
+| The scope dimension | a "one per workspace" domain appears and composite keys cannot express it | DomainSpec gains a scope declaration + a scope segment in file names (encodeSegment) | the name character set is already restricted; file names cannot collide |
+| Cross-table atomic transactions | one business operation touching two tables of one domain atomically | `domain.transact(fn)`; JSON whole-unit rewrite is naturally atomic, SQLite wraps a transaction | — |
+| Secondary indexes / conditional queries | in-memory filtering stops scaling (tens of thousands of records) | SQLite JSON1 over the value column, a read-only query facet on the seam | the JSON backend does not follow |
+| Moving a session across workspaces | a product need appears | relax the attach check into a "detach first, then attach" orchestration | — |
+| RPC/GUI/boot | next phase | `workspace.*` + `session.delete` endpoints, wire schemas, boot mounting, sidebar on real data | this phase's model and semantics are the direct source of the wire projection |
+
+## Alternatives considered
+
+- **Reusing session-persistence's coordinator/backends**: event-log semantics (append-only, turn crash repair, lazy materialization) do not match KV overwrite semantics; only the layering idea is borrowed (a coordination layer owns write ordering, backends implement minimal primitives).
+- **A workspace-specific storage package, seam extracted later**: the second consumer (the session sidecar) is already foreseeable; generalizing later means touching the interface twice.
+- **Merging domain and storage into one layer**: backends would be forced to touch schema validation, change events, and write serialization — domain concerns; split apart, storage backends implement only opaque primitives (the smallest replaceable surface) while the single domain implementation concentrates all domain logic (zod/events/serialization written once, not doubled per backend).
+- **JSON backend as jsonl append + tombstones + compaction**: temp+fsync+rename crash safety is equivalent to append; rewriting keeps the file the net current state, human-readable, with no folding/compaction/torn-line tolerance; at domain scale a full rewrite costs the same as appending a line.
+- **JSON one file per table**: under whole-file rewrites the file granularity does not affect write cost; merging per domain means fewer files and gives the global singleton a home.
+- **SQLite storing a whole domain as one blob row**: any single-record change rewrites the whole domain, forfeiting per-key precise updates — SQLite's only edge over JSON reduced to zero.
+- **SQLite generating typed columns from the schema**: a DDL generator is over-engineering; document-per-row suffices, revisit when real query needs appear.
+- **One sqlite db file per domain**: contrary to the repository's one-database-many-tables convention.
+- **A single whole-store backend choice (the session-persistence single-slot pattern)**: the initial design; changed to coexisting backends + configured routing because the hub will carry multiple data forms whose backend preferences (human-readable vs high-frequency point updates) are bound to diverge — a single slot forces the coarse "swap everything + hand-migrate data" move. The cost is one extra name lookup, backed by fail-loud.
+- **path as the workspace key**: normalization/symlink resolution rewrites the path; reference anchors must be stable.
+- **Ownership derived from cwd (or merged with the ledger)**: two sources of truth; cwd cannot express ordering; ownership is a workspace-side fact to begin with.
+- **Change events carrying the old value**: the repository's change-event convention is "new snapshot + operation discriminant" (the sole exception, fs's before/after, is a method return value rather than an event, because the old value is unrecoverable afterwards and has a diff consumer); consumers needing diffs hold their own previous snapshot.
+- **Delete auto-cancelling a running session**: the persistence/orchestration layer reaching back into the runtime dirties the layering; cancel already exists, callers compose it.
+
+## Acceptance criteria
+
+- This phase's four test suites all green: the shared backend contract suite on both json/sqlite, registry/mount disposer semantics, the domain layer (including the six open steps and fail-loud routing), and full workspace semantics (create/attach checks/consistency doctrine).
+- `ctx.workspace` completes the create → attach → list lifecycle under a test assembly (deletion is future work).
+- Zero diff in the session-persistence packages (the acceptance line for not touching the session side this phase).
+- No new snapshots this phase (no model-visible or assembly surface); added next phase with the RPC wiring.
+
+## Risks
+
+- **The repository's first push-mode change event on a persistence surface** (session-persistence polls revisions): the shape has the `goal/changed` template, but "the storage layer emits events" is a new precedent, validated only when next phase's RPC consumes it.
+- **The JSON backend's whole-unit rewrite scale premise**: if the second consumer (the session sidecar) lands on the JSON backend at thousand-record scale before being routed to SQLite, the rewrite cost surfaces earlier than expected; the mitigation is exactly `routes` pointing at sqlite.
+- **The deletion orchestration's weak dependency on `ctx.sessions`**: a headless assembly without the runtime registry treats it as "no hot sessions", leaving a window (an external process running the session); multi-process is already out of scope, accepted.
+- **Facet generalization designed against the future `log` facet without implementing it this phase**: a "reserved shape does not fit" risk; mitigated by organizing both backends' medium code in the sinkable shape from the reuse audit, so when the `log` facet lands only the facet layer moves.

+# Agent Note: Domain KV storage capability seam and the workspace entity
+
+Status: proposed
+
+[English](2026-07-24-domain-kv-storage-and-workspace.md) | 中文
+
+## Problem
+
+host 侧唯一的持久化面是 session 事件日志（`packages/session-persistence`：append-only、一 session 一文件）。凡是"不属于某个 session"的信息就没有落盘处，眼下有两个真实需求：
+
+- **workspace 实体**。GUI 要把 workspace 做成真实对象：路径、标题、关联 session 清单。归属关系由 workspace 持有——"哪些 session 属于这个 workspace"不是任何单个 session 自己的事实，塞进 session log 语义不成立。此前 workspace 只是 sidebar 上按 cwd 分组的视觉概念，没有实体（该结论已被推翻）。
+- **session 动态元信息**（可预见的第二个消费者）。冷会话列表只读日志首行 header（创建时的不可变快照），title、结束状态这类随会话推进变化的信息拿不到；补齐方向是 sidecar 元数据表——正是一张按 key 高频点更新的 KV 表。
+
+另外，workspace 删除最终需要删除其关联 session，而 `SessionPersistence` 没有删除原语，host 也没有 `session.delete` 端点——该空白的设计随本 Note 定案，但实施标记为 future work：本期不动 session 侧任何代码。
+
+## Proposal
+
+新建 `packages/storage/` 组——`ctx.storage` 存储枢纽（后端注册面 + 数据形式挂载面）、两个后端、domain 领域数据形式——及 workspace 消费者包；给 `SessionPersistence` 扩删除原语。
+
+| 包 | 路径 | ctx 面 | 本期 |
+| --- | --- | --- | --- |
+| `@deepseek-ai/dsh-storage` | `packages/storage/storage/` | `ctx.storage`（枢纽） | ✓ |
+| `@deepseek-ai/dsh-storage-json` | `packages/storage/storage-json/` | 注册 backend `json` | ✓ |
+| `@deepseek-ai/dsh-storage-sqlite` | `packages/storage/storage-sqlite/` | 注册 backend `sqlite` | ✓ |
+| `@deepseek-ai/dsh-storage-domain` | `packages/storage/storage-domain/` | 挂载 `ctx.storage.domain` | ✓ |
+| `@deepseek-ai/dsh-workspace` | `packages/workspace/workspace/` | `ctx.workspace` | ✓ |
+| `SessionPersistence.delete` 扩面 + 级联删编排 | `packages/session-persistence/*` | 既有 seam 新方法 | ✗ future work（本期不动 session 侧） |
+| `workspace.*` / `session.delete` RPC、GUI 接线、boot 组装 | — | — | ✗ 下期 |
+
+（workspace 放独立组不放 `packages/host/`：host 组命名规则要求 `dsh-host-*` 前缀，而包名定为 `dsh-workspace`；且 workspace 实体是领域概念，不绑定 host 装配层。与既有 `workspace-context` 包无关——那是 AGENTS.md 指令加载器。）
+
+依赖方向：`dsh-workspace` → `dsh-domain` → `dsh-storage` ← 两后端。`dsh-workspace` 另依赖 `ctx.sessionPersistence` 的只读面（attach 的 cwd 校验读 session header；服务缺席时 attach 直接拒绝——无法校验即不写账）。session 删除相关的 `ctx.sessions` 运行中检查随级联删一并归入 future work。
+
+### `dsh-storage`：存储枢纽
+
+纯注册枢纽，自身不做 IO，无 Config。`Storage` service 挂 `ctx.storage`，两个面：`backend`（`BackendRegistry`：`register(name, backend)` 返回 disposer、重名 throw；`get(name)` 未知名 throw `backend-not-found`）与数据形式挂载（`mount(form, facility)` 配 merge-extensible 的 `StorageForms` map，`dsh-domain` merge 进 `domain` 键；未挂载访问 throw `form-not-mounted`）。签名正文见 `packages/storage/storage/src/index.ts` 与 `src/registry.ts`。
+
+**多后端同时挂载**；域→后端的选择是 `dsh-domain` 的配置（见下），不是全局二选一。disposer 语义 = 从表中摘名；后端自身的 close 由后端包的 effect 闭包负责，顺序先摘名后 close。
+
+一个后端是一个**介质 owner**（一棵文件树 root / 一个 db 文件），通过**数据形状 facet** 暴露原语——本期只有 `kv`；session 迁移期加 `log`（见迁移节）。facet 是可选成员，缺席即该后端不支持该形状，解析时 fail loud。`kv` facet 的原语面：`open(descriptor)`（descriptor = 名字/版本/表名清单/有无 global，名字与表名限 `^[a-z][a-z0-9_]*$` 兼作文件名与 SQL 表名段）返回 unit，unit 提供 `loadAll` / `putRecord` / `deleteRecord`（缺 key 为 no-op）/ `setGlobal` / `close`（幂等）；值对后端是不透明 JSON。规范正文（含逐方法 JSDoc）在 `packages/storage/storage/src/backend.ts`。
+
+backend 契约（共享契约测试逐条断言，两后端同套件）：
+
+1. `open` 对不存在的介质创建（懒物化允许：可延迟到首写，但 `loadAll` 立即可用返回空表）；对已存在介质载入。
+2. 介质上版本 ≠ descriptor.version → `StorageError('version-mismatch')`，不迁移不重建。
+3. 持久性：写原语 resolve 后进程崩溃再 open，`loadAll` 必须反映该写入。
+4. 后端不承诺 unit 内写并发序——**调用方负责串行**；后端只保证单次调用原子（JSON 整文件替换 / SQLite 单语句）。
+5. `deleteRecord` 幂等；`putRecord` 覆写。
+6. 任意字符串 key / 任意 JSON 值安全（key 不进文件路径，结构性质）。
+7. `close` 幂等；close 后任何操作 → `StorageError('closed')`。
+
+错误词汇是带 code 判别的 `StorageError`，码表：`backend-not-found` / `form-not-mounted` / `duplicate-backend` / `duplicate-mount` / `version-mismatch` / `malformed-medium` / `closed`（`packages/storage/storage/src/error.ts`）。
+
+### `dsh-storage-json`
+
+Config 仅 `root`（必填无默认，schemastery）；apply 在 `ctx.effect()` 里注册后端 `json`，disposer 先摘名再 `backend.close()`。
+
+- 布局 `<root>/<unitName>.json`，一 unit 一文件；目录 0o700、文件 0o600。
+- 文件格式（版本戳在头，文件即当前净值，`JSON.stringify(…, null, 2)` 肉眼可读——这是该后端的存在理由）：
+
+```json
+{
+ "unit": { "name": "workspace", "version": 1 },
+ "global": null,
+ "tables": { "workspaces": { "<key>": {} } }
+}
+```
+
+- 写入：任何一次写原语 = 内存态全量序列化 → temp 写 + fsync → rename 原子发布（Windows 变体照抄 session-persistence-jsonl 的 win32 路径）。内存态是权威，盘是投影。
+- `loadAll`：open 时整文件 parse；缺 `unit` 头、tables 非对象等 → `malformed-medium`。文件不存在 = 空单元，首写才落盘。
+
+### `dsh-storage-sqlite`
+
+Config 为 `path`（必填，`':memory:'` 允许）+ `journalMode`（枚举，默认 `wal`）；apply 同 json，注册后端 `sqlite`。
+
+- `node:sqlite` `DatabaseSync`；打开序列照抄 session-persistence-sqlite：mkdir 0o700 → 不存在则 `open(path,'wx',0o600)` 独占建文件 → `PRAGMA foreign_keys=ON` → journal_mode → 版本检查 → 建表。
+- 物理布局版本 `STORAGE_SQLITE_SCHEMA_VERSION = 1` 存 `PRAGMA user_version`：0 → 盖章；≠ → `version-mismatch`。
+- DDL（全 STRICT；表名由受限字符集拼接加 `u_` 前缀，杜绝外部输入进 DDL）：
+
+```sql
+CREATE TABLE IF NOT EXISTS units (name TEXT PRIMARY KEY, version INTEGER NOT NULL) STRICT;
+CREATE TABLE IF NOT EXISTS unit_globals (
+ unit TEXT PRIMARY KEY REFERENCES units(name), value TEXT NOT NULL) STRICT;
+-- 每 unit 每表：
+CREATE TABLE IF NOT EXISTS "u_<unit>_<table>" (
+ key TEXT PRIMARY KEY, value TEXT NOT NULL) STRICT; -- value = 记录 JSON 文档
+```
+
+- unit 版本存 `units` 行，descriptor 不符 → `version-mismatch`。行粒度 document-per-row，保住按 key 精确落盘更新（为 session sidecar 这类高频点更新大表留路）；查询需求出现时 JSON1 直查 value 列。
+- 写原语单语句即原子，无跨语句事务需求（domain 层无跨表事务，见不做清单）。
+
+### `dsh-domain`：领域数据形式
+
+单实现不抽象；消费者只依赖这层，不直接触后端。
+
+```ts ignore-check
+export const Config = z.object({
+ backend: z.string().required(), // 默认后端名，必填
+ routes: z.dict(z.string()).default({}), // per-domain 覆盖：{ workspace: 'sqlite' }
+})
+
+export function apply(ctx: Context, config: Config) {
+ ctx.effect(() => ctx.storage.mount('domain', new DomainFacility(ctx, config)))
+}
+```
+
+（facility 卸载顺序：先 dispose 各域（排空写链）再从枢纽摘名——排空期间在途写仍发 `domain/changed`，事件一致性 invariant 经 facility 反查域，要求此时域名仍可解析。）
+
+域声明（spec 对象由拥有该域的包定义导出，是类型与运行时的单一来源；schema 用 zod，`z.infer` 推导类型不重复声明——记录模型下期要投影成 RPC wire schema，wire 边界全是 zod；schemastery 仍只管插件 Config）：
+
+```ts ignore-check
+export interface DomainGlobalSpec<G> { readonly schema: ZodType<G>; readonly initial: G }
+export interface DomainTableSpec<K extends string, V> { readonly valueSchema: ZodType<V> }
+
+export interface DomainSpec {
+ readonly name: string // ^[a-z][a-z0-9_]*$
+ readonly version: number
+ readonly global?: DomainGlobalSpec<unknown>
+ readonly tables: Record<string, DomainTableSpec<string, unknown>>
+}
+
+export function defineDomain<S extends DomainSpec>(spec: S): S
+export function domainTable<K extends string, V>(schema: ZodType<V>): DomainTableSpec<K, V>
+```
+
+`DomainFacility.open(spec)` 精确语义（顺序执行，任一步失败即整体失败）：
+
+1. 同名域已打开 → `DomainError('already-open')`。
+2. 后端名 = `config.routes[spec.name] ?? config.backend`；`ctx.storage.backend.get(name)`（未挂载穿透 `backend-not-found`——misconfiguration fails loud）。
+3. 后端无 `kv` facet → `DomainError('facet-unsupported')`。
+4. `kv.open(descriptorOf(spec))`（descriptor 由 spec 直接投影）。
+5. `loadAll()`；每条记录 `valueSchema.parse`，global 过 schema（null 取 `initial`，不落盘，首写才落盘）。失败 → `DomainError('invalid-record', { table, key })`（durable 边界必须校验；写侧不重复校验）。
+6. 构造 `Domain` 并注册 `ctx.effect()`：disposer 排空写链 → `unit.close()`。
+
+```ts ignore-check
+export interface Domain</* 由 spec 推导 */> {
+ readonly name: string
+ readonly global: { get(): G; set(value: G): Promise<void> } // 仅当 spec.global 声明
+ table<N extends keyof S['tables']>(name: N): KvTable<KeyOf<N>, ValueOf<N>>
+}
+
+export interface KvTable<K extends string, V> {
+ get(key: K): V | undefined // 内存快照，同步
+ entries(): IterableIterator<[K, V]>
+ keys(): IterableIterator<K>
+ readonly size: number
+ put(key: K, value: V): Promise<void>
+ delete(key: K): Promise<boolean> // false = 本就不存在
+ /** Atomic read-modify-write on the domain's single write chain; fn is sync-pure. */
+ update(key: K, fn: (current: V) => V): Promise<V> // 缺 key → DomainError('missing-key')
+}
+```
+
+规则：
+
+- **一级 mapping**：key → 记录，不做嵌套表；层级需求用复合 key 或值内字段。两后端因此同构（JSON object 一层 ↔ SQLite 一行）。
+- **记录是纯数据**：可直接 JSON 序列化的不可变 POJO；`get`/`entries` 返回值不得原地改（TypeScript readonly 投影，不做运行时冻结）。带行为的领域对象属于消费者包。
+- **写串行**：域内一条 promise 链，`put`/`delete`/`update`/`global.set` 全排队；`update` 的 fn 在链上执行，并发不交错。不做 active-record（取出可变对象自动落盘——落盘时机不可控，与整域原子覆写冲突）。
+- **版本 fail loud**：盘上版本与 spec 不符直接报错，不迁移不重建（数据不可再生，pre-release 拒绝旧格式）。
+- **变更事件**：每次写落盘 resolve 后 emit `domain/changed`（`@mode emit`），逐条发、不带旧值（对齐仓库"新快照 + 操作判别"惯例，范本 `goal/changed`）；payload `DomainChanged` 是 put/deleted 判别联合——域名 + 表名 + key（global 变更两者为 `''`）+ operation，put 支带新快照 value、deleted 支无 value（`packages/storage/storage-domain/src/events.ts`）。此为下期 RPC 推帧的事件源。错误词汇 `DomainError`，码表：`already-open` / `facet-unsupported` / `invalid-record`（带 `{ table, key }`）/ `missing-key` / `closed`。
+
+### Future work：session 侧删除（设计定案，本期不实施）
+
+本节是定案的施工规范，实施期不动语义只动代码；本期 session-persistence 的任何文件都不修改。
+
+```ts ignore-check
+export abstract class SessionPersistence extends Service {
+ /**
+ * Permanently delete one session's stored log.
+ * Queued on the per-id write chain (serialized with in-flight appends).
+ * Unknown id → reject; un-materialized create intent → cancel it and resolve.
+ * After deletion the id behaves as unknown for every subsequent operation.
+ */
+ abstract delete(id: SessionId): Promise<void>
+}
+```
+
+- JSONL 后端：unlink 该 session 文件（含 `.zstd` 变体）；文件与 intent 均无 → reject。
+- SQLite 后端：单事务 `DELETE FROM events…; DELETE FROM sessions…`；0 行命中且无 intent → reject。
+- 删除成功后 emit `'session-persistence/deleted'(id: SessionId)`（`@mode emit`；session-persistence 层事件面，与 `domain/changed` 无关）。派生数据（session-query 全文索引等）订阅自清；持久层不直连索引，崩溃窗口靠派生索引可丢弃重建兜底。
+
+编排层规则（随级联删一起实施；`session.delete` RPC 与 workspace 级联复用同一规则）：
+
+| 检查（按序） | 不满足时 |
+| --- | --- |
+| 目标（递归时含整棵子树）无一在 `ctx.sessions` 运行 | throw，什么都不删；调用方先 cancel 再删，持久层不反向牵动运行时 |
+| 非递归时目标无后代（后代 = `parentSessionId` 传递闭包，由 `list()` header 求得） | throw：默认只能删叶子，`recursive: true` 显式递归 |
+| 递归序自底向上（叶→根） | ——中途崩溃只留"子树删一半、祖先在"，重跑收敛，任何时刻无悬空 parent |
+| 级联中某 id 已不在盘上 | 跳过（幂等续删）；其余错误中止 |
+
+### `dsh-workspace`
+
+包拥有 `WorkspaceId` brand，暴露 `ctx.workspace`。记录 key 为生成的 uuid——path 不做 key：规范化会改写它，引用锚点必须稳定。
+
+```ts ignore-check
+export type WorkspaceId = Branded<'WorkspaceId'>
+export function WorkspaceId(id: string): WorkspaceId
+
+const workspaceRecord = z.object({
+ path: z.string(), // realpath，见下
+ title: z.string(),
+ sessionIds: z.array(z.string().transform(SessionId)),
+ createdAt: z.string(), // ISO
+ updatedAt: z.string(),
+})

+- **path 规范**：落盘值 = `fs.realpath(输入)`（尾斜杠、`..`、符号链接全解析）；唯一性 = 规范化后字符串相等（符号链接指向同一目录算撞）。目录不存在时 create 直接 reject（realpath 失败——workspace 必须指向存在目录；"Create new = 建目录"是上层交互，先 mkdir 再 create）。attach 校验的 session cwd 同口径。cwd 单值 + path 唯一 ⇒ 一个 session 结构上最多归属一个 workspace，双重记账写侧不可能。
+- **title**：显示名，默认 `basename(path)`，可改，允许重复。归属不用 cwd 派生兜底——cwd 表达不了排序，归属是 workspace 侧事实；headless 直开的 session 不属于任何 workspace。
+- 消费者只见 `Workspace` 接口，`WorkspaceEntity` 不出包（单实现不预拆 seam）；实体按 id 唯一（registry 缓存），记录快照写后原地换新，外部只见 getter；所有写收敛到实体内 `mutate(fn)` → `table.update`，`updatedAt` 在 mutate 内统一刷。领域对象不过 RPC，下期 wire 层把记录投影成 zod wire schema。
+- **workspace 删除整体为 future work**（2026-07-24 拍板）：本期 registry 不提供 delete 方法——半截的"只删记录留 session"语义不对外暴露，删除与 session 级联（`recursive` 参数、运行中检查、自底向上、崩溃重跑收敛）作为一个完整语义随 session 删除原语一起落地；届时顺序为逐个删 session → 摘账 → 删记录。
+
+一致性口径（账 = 归属唯一依据；实现与测试基准）：
+
+| 情形 | 行为 |
+| --- | --- |
+| 账中 id 盘上无 session | `list()`/实体投影时过滤；下次任何 mutate 顺手摘除；不报错（删除崩溃一致性的正常产物） |
+| session cwd 匹配某 workspace 但未上账 | 不属于：不合并不收编。GUI 将来可做"游离 session"专区（游离 = 全部账的补集） |
+| 同一 session 上两本账 | 写侧结构性堵死（attach 校验）；load 检出 → throw（外部手改数据，不掩盖） |
+| workspace 目录不存在 | 记录与账保留，`status()` = `'missing-dir'`；存储层不自动删（目录可能只是暂时挪走） |
+
+### 复用与 session 后端迁移展望
+
+**长期方向**：session-persistence 的 JSONL/SQLite 后端里"纯介质操作"下沉到 `dsh-storage` 后端（session 包不删，`SessionPersistence` seam 与 coordinator 语义不动；动的只是它们脚下的文件/db 操作层）。复用的动机：介质层全是文件系统操作、数据库调用与跨平台兼容的脏活（Windows 权限与原子发布变体、fsync 语义、独占建文件……），这些只应写一遍；业务语义（session 怎么 append、何时 append、append 什么）留在上层——而"底下这次 append 是否正常完成"（持久性/原子性/平台正确性）是底层的责任，责任界面就是 facet 原语的契约。为此后端接口按**介质 owner + 数据形状 facet** 设计：session 日志是 append-only 流，与 KV 形状不同——强行统一进 KV 原语会两头变形，所以按 facet 分开（`kv` 本期、`log` 迁移期），介质与生命周期共享。
+
+现状复用审计（迁移前就能看清的账）：
+
+| session-persistence 现有逻辑 | 归属 | 处置 |
+| --- | --- | --- |
+| JSONL：temp 写 + fsync + link/unlink 原子发布、0o700/0o600 权限、Windows 变体（win32.ts） | 纯介质 | 本期 `dsh-storage-json` 直接抄用（整文件原子覆写正是同一套）；迁移期成为共享实现 |
+| JSONL：逐行 append、首行 header 快读、zstd 逐帧压缩 | log 形状 | 留在原地；迁移期进 `log` facet |
+| SQLite：openDatabase（mkdir/独占建文件/PRAGMA 序列/user_version 检查） | 纯介质 | 本期 `dsh-storage-sqlite` 抄用——两处 openDatabase 已几乎逐行同构，本组是第三个使用者；先抄后提，提取放迁移期 |
+| SQLite：events/sessions 表结构、同事务物化 | log 形状 | 留在原地；迁移期进 `log` facet |
+| coordinator（per-id 写链、懒物化、崩溃修复、flush 屏障） | session 语义 | 永不下沉——事件日志的领域逻辑，对应物在 domain 层（写串行链），各归各 |
+| encodeSegment（id 进路径转义） | 介质工具 | domain 侧 key 不进路径用不到；`log` facet（一 session 一文件）迁移时随之下沉 |
+
+**本期不改 session-persistence 的介质代码**（只加 delete 原语）；上表是迁移期的施工清单，也是后端接口"必须装得下 log 形状"的设计依据。
+

+
+## Alternatives considered
+
+- **复用 session-persistence 的 coordinator/后端**：事件日志语义（append-only、turn 崩溃修复、懒物化）与 KV 覆写语义不匹配；只借其分层思想（协调层持写序、后端只实现最小原语）。
+- **workspace 专用存储包，后续再抽 seam**：第二个消费者（session sidecar）已可预见，届时泛化要再动一次接口。
+- **domain 与 storage 合为一层**：后端会被迫接触 schema 校验、变更事件、写串行等领域关切；拆开后 storage 后端只做不透明原语（可替换面最小），domain 单实现收敛全部领域逻辑（zod/事件/串行化只写一遍，不随后端翻倍）。
+- **整库单后端二选一（学 session-persistence 单坑位模式）**：曾是初版方案；改为多后端并存 + 配置路由，因为存储枢纽要承载多种数据形式，不同形式/域对后端的偏好（肉眼可读 vs 高频点更新）注定分化，单坑位会逼出"整体换挂 + 手工导数据"的粗粒度动作。代价是按名查找多一步，fail-loud 兜底。
+- **JSON 后端 jsonl 追加 + 墓碑 + 压实**：temp+fsync+rename 的崩溃安全与 append 等价；覆写让文件永远是净值、肉眼可读，免掉折叠/压实/断行容错。域规模下整写与追加一行同量级。
+- **JSON 一表一文件**：覆写下文件粒度不影响写成本，按域合并文件更少，global 单例有落点。
+- **SQLite 整域存单行 blob**：任何一条记录变更都重写整域，失去按 key 精确更新——SQLite 相对 JSON 的唯一优势归零。
+- **SQLite 按 schema 生成 typed columns**：DDL 生成器过度建设；document-per-row 足够，查询需求出现再议。
+- **每域独立 sqlite db 文件**：与仓库一库多表惯例相反。
+- **path 作为 workspace key**：规范化/符号链接解析会改写 path；引用锚点必须稳定。
+- **归属用 cwd 派生（或与账合并）**：双真相源；cwd 表达不了排序；归属本就是 workspace 侧事实。
+- **变更事件带旧值**：仓库变更事件惯例是"新快照 + 操作判别"（唯一例外 fs 的 before/after 是方法返回值而非事件，因旧值事后不可重建且有 diff 消费者）；需要 diff 的消费者自己持有上次快照。
+- **删除自动 cancel 运行中 session**：持久层/编排层反向牵动运行时，层次变脏；cancel 机制已存在，调用方组合即可。
+
+## Acceptance criteria
+
+- 测试矩阵本期四套件全绿：backend 契约共享套件在 json/sqlite 双端、registry/mount disposer 语义、domain 层（含 open 六步与路由 fail-loud）、workspace 全语义（create/attach 校验/一致性口径）。
+- `ctx.workspace` 可在测试组装下完成 create → attach → list 生命周期（删除为 future work）。
+- session-persistence 包零 diff（本期不动 session 侧的验收线）。
+- 本期无新快照（无模型可见面与组装面）；下期 RPC 接线时补。
+
+## Risks
+
+- **仓库持久化面第一个推式变更事件**（session-persistence 靠 revision 轮询）：形态虽有 `goal/changed` 范本，但"存储层发事件"是新先例，下期 RPC 消费时才能验证形态是否合适。
+- **JSON 后端整域覆写的规模前提**：若第二个消费者（session sidecar）在路由到 SQLite 前就以千级记录落在 JSON 后端，整写成本会先于预期显现；缓解即 `routes` 改指 sqlite。
+- **删除语义的编排层检查依赖 `ctx.sessions` 弱依赖**：headless 组装拿不到运行时注册表时按"无热 session"处理，存在窗口（外部进程正在跑该 session）；多进程本就在不做清单内，接受。
+- **facet 泛化以未来的 `log` facet 为设计依据但本期不实现它**：存在"预留形状不合身"的风险；缓解是本期后端介质代码按复用审计表的下沉形状组织，`log` facet 真正落地时只动 facet 层。

+# Agent Note: Separate context injection from turn execution
+
+Status: proposed
+
+English | [中文](2026-07-24-separate-context-injection-from-turn-execution.zh.md)
+
+## Problem
+
+The agent API currently represents supplementary model-facing input in three overlapping ways: callers attach `HookContext[]` through `SendOptions.contexts`, interception and tool hooks return `additionalContexts`, and plugins call `agent.inject()`. These paths eventually write context into the same model history, but they carry different placement, metadata, admission, queue, and turn-lifecycle rules.
+
+Atomic attachment to an inbox message forces the loop to preserve context through prompt admission, steering conversion, cancellation, and terminal discard. `prompt-prefix` placement then combines context and the direct prompt into one event, requiring a model-hidden envelope so transcript consumers can recover what the user actually wrote. The result makes outbox entries, session projection, and UI replay responsible for a distinction that belongs to the producer.
+
+Idle `inject()` exposes a second mismatch. Injection does not request model execution, yet the current implementation opens and closes a zero-step `injection` turn solely to satisfy the turn-enclosure invariant and obtain a durability checkpoint. A turn therefore sometimes means “run the agent loop” and sometimes means “persist context without running it.”
+
+`HookContext` also names its producer rather than its role. The value may come from a native plugin, a hook bridge, prompt admission, or tool post-processing. Its stable meaning is simply additional model-facing context with provenance.
+
+## Proposal
+
+Make `inject()` the only caller-facing operation for adding supplementary model-facing input, and define a turn exclusively as one execution of the model loop.
+
+Remove `SendOptions.contexts`. A caller that owns context delivers it with `inject()` and independently submits the direct message with `send()` or `steer()`. Rename `HookContext` to `AdditionalContext`; retain only `content` and `source`, and remove placement and model-hidden metadata from this shared shape.
+
+Prompt and tool extension points may still return `additionalContexts`. These values are outputs of the extension point, not attachments captured from a caller's inbox item. Prompt admission runs before `run()` opens a turn. An allowed prompt enters the outbox together with its returned additional contexts; a blocked prompt writes neither and opens no turn. Tool-produced additional contexts enter the same outbox after the corresponding tool results.
+
+Every additional context becomes an independent `user/message` whose `source` records provenance. Remove `context/message`, prompt-prefix placement, the stable request delimiter, and the prompt envelope. Transcript and UI consumers distinguish direct user messages from injected context by `source`, not by recovering a hidden direct-prompt field from combined model content.
+
+## Injection lifecycle
+
+When a turn is open, `inject()` stages the context in the loop outbox. The loop drains the outbox at a safe step boundary, preserving tool protocol adjacency: a context accepted during an assistant tool-call batch appears only after that batch's complete ordered results. Taking the outbox as a whole makes steering and injected context accepted for one boundary visible to the same following request.
+
+When no turn is open, `inject()` appends its `user/message` immediately and starts a session flush. It does not increment turn numbering, emit `turn/start` or `turn/end`, change agent status, or run the model. The synchronous API still returns before the asynchronous flush settles; `whenIdle()` and agent disposal include outstanding idle-injection flushes in their quiescence boundary.
+
+A failed idle flush has no legitimate turn or step coordinates. It is reported through logging or a persistence-owned error surface, not by inventing an `agent/error` payload for a nonexistent turn. The in-memory event remains accepted and a later flush may retry persistence.
+
+The session invariant therefore permits `user/message` between turns while continuing to require turn enclosure for execution events, steering, assistant output, tools, and package-added events by default. Persistence, recovery, resume, fork, and compaction code must treat a valid out-of-turn `user/message` as committed session history rather than an interrupted or discardable turn tail.
+
+## Extension and caller semantics
+
+`PromptDecision.content` continues to replace only the direct prompt. `PromptDecision.additionalContexts` and tool-result `additionalContexts` retain FIFO order and individual provenance, but no longer select placement. A waterfall listener that delegates with `next()` must preserve downstream prompt content and additional contexts unless it intentionally returns replacements.
+
+Caller-driven injection and hook-produced additional context deliberately have different admission ownership. A hook's additional contexts materialize only after that hook allows the prompt or tool result. A caller that invokes `inject(context)` and then `send(prompt)` has already committed context independently; if prompt admission later blocks the prompt, the injected context remains in history. Callers requiring all-or-nothing domain behavior must perform their own preparation before either operation or expose a domain-specific admission seam.
+
+Cross-session references follow the ordinary composition: the host prepares the snapshot, injects it with session-reference provenance, then sends or steers the readable direct prompt. The target log contains two simple messages, so later source mutation cannot change replay and transcript consumers do not need a prompt envelope. This supersedes the attachment mechanism in the [cross-session reference decision](../../implemented/feature/2026-07-21-cross-session-references.md) while retaining its snapshot and trust-boundary rules.
+
+This proposal preserves the caller-owned framing decision from [unwrapped injected content](../../implemented/simplification/2026-07-20-unwrap-injected-content-envelopes.md), the one-item turn rule from [one send, one turn](../../implemented/simplification/2026-07-17-one-send-one-turn.md), and narrows the [turn-enclosure decision](../../implemented/architecture/2026-06-15-turn-enclosure-invariant.md) so turns enclose execution rather than every session event.
+
+## Alternatives considered
+
+**Keep `SendOptions.contexts` as an atomic attachment.** This preserves all-or-nothing delivery when prompt admission blocks, but it keeps context inside inbox lifecycle state and requires every queue transition and observation event to carry it. The generic agent API should not encode a domain transaction that most callers can express as context injection followed by message delivery.
+
+**Keep a distinct `context/message` session event.** A separate event makes the out-of-turn exception narrower, but user-role model input would again have two event types with identical projection. `user/message.source` already carries the distinction needed by policy, transcript, and replay consumers.
+
+**Keep one-shot turns for idle injection.** This retains universal turn enclosure and a convenient flush boundary, but it makes turn counts and turn observers report work that never ran the model. Durability is an independent session concern and can be awaited without fabricating execution.
+
+**Keep `prompt-prefix` as an optional placement.** Prefix baking can make the context and request appear in one provider message, but it introduces a second representation of the direct prompt and spreads placement handling across admission, steering, logging, replay, and UI code. Producers that require textual framing may include it in their own context content.
+
+**Let hooks call `inject()` directly instead of returning additional contexts.** Direct injection would erase the extension point's admission ownership: a listener could append context before a downstream listener blocks the operation. Returning `additionalContexts` keeps the waterfall result authoritative while sharing the same post-admission outbox path.
+
+## Acceptance criteria
+
+- `SendOptions` and steering inbox records contain no attached contexts; `agent/queued` reports only the retained message and steering facts.
+- `AdditionalContext` replaces `HookContext` across prompt interception, tool execution, hook bridges, guards, and context producers, with only `content` and `source`.
+- Prompt-prefix placement, prompt envelopes, and `context/message` are absent from public types, durable events, projection, and UI replay.
+- Idle `inject()` appends and flushes one sourced `user/message` without a turn or model call; `whenIdle()` and disposal await the flush.
+- Active-turn injection and hook-produced contexts drain at safe boundaries after complete tool-result batches and before the request that consumes them.
+- Blocked prompt admission opens no turn and appends neither the prompt nor hook-produced additional contexts; independently injected caller context remains.
+- Unit, persistence/resume, invariant, ACP/TUI replay, and keyless assembled-application snapshots cover the new event order and durability semantics.
+
+## Risks
+
+- Allowing one surface event outside turns weakens a simple invariant and may expose hidden assumptions in persistence scanning, crash repair, forking, compaction, and session queries.
+- Consecutive user-role messages replace one baked prompt message; provider adapters and cache behavior must accept and preserve that ordering.
+- `inject()` followed by a blocked `send()` leaves context without its intended direct prompt unless the caller accepts the independent-commit contract.
+- A synchronous injection API cannot return flush failure. Logging alone is less structured than `agent/error`, while adding a new persistence event solely for this case may create another unnecessary seam.
+- Removing attachment, placement, metadata, envelopes, and a durable event type is a broad pre-release migration that must update every producer and consumer atomically.

+# Agent Note: 将上下文注入与轮次执行分离
+
+Status: proposed
+
+[English](2026-07-24-separate-context-injection-from-turn-execution.md) | 中文
+
+## 问题
+
+agent API 目前用三种相互重叠的方式表示面向模型的补充输入：调用方通过 `SendOptions.contexts` 附加 `HookContext[]`，拦截钩子和工具钩子返回 `additionalContexts`，插件则调用 `agent.inject()`。这些路径最终都会把上下文写入同一份模型历史，但各自携带不同的放置、元数据、准入、队列和轮次生命周期规则。
+
+将上下文原子附加到收件箱消息后，agent loop（智能体循环）必须让上下文跟随提示词准入、steering（中途引导）转换、取消和终止丢弃的完整生命周期。`prompt-prefix` 放置方式又会把上下文与直接提示词合并为一个事件，因此 transcript（文本记录）消费方需要依赖模型不可见的封套，才能还原用户实际输入。这样一来，outbox 条目、会话投影和 UI 回放都必须处理本应由生产方负责的区分。
+
+空闲状态下的 `inject()` 还暴露了另一处语义错位。注入并不请求模型执行，但当前实现仅为了满足轮次封闭不变量并获得持久性检查点，就会打开并关闭一个零步骤的 `injection` 轮次。于是，轮次有时表示「运行 agent loop」，有时却表示「不运行 agent，仅持久化上下文」。
+
+`HookContext` 的名字也描述了生产方，而非该值的职责。它可能来自原生插件、hook bridge、提示词准入或工具后处理；其稳定含义只是带来源信息的额外模型上下文。
+
+## 提案
+
+将 `inject()` 设为调用方添加补充模型输入的唯一操作，并把轮次严格定义为一次模型循环执行。
+
+移除 `SendOptions.contexts`。拥有上下文的调用方通过 `inject()` 交付上下文，再独立使用 `send()` 或 `steer()` 提交直接消息。将 `HookContext` 重命名为 `AdditionalContext`；这个共享结构只保留 `content` 和 `source`，移除放置方式与模型不可见元数据。
+
+提示词和工具扩展点仍可返回 `additionalContexts`。这些值是扩展点的输出，而不是从调用方收件箱条目捕获的附件。提示词准入在 `run()` 打开轮次之前执行。提示词获准后，它与返回的额外上下文一同进入 outbox；提示词被阻止时，两者都不写入，也不打开轮次。工具产生的额外上下文则在对应工具结果之后进入同一个 outbox。
+
+每项额外上下文都成为独立的 `user/message`，并由 `source` 记录来源。移除 `context/message`、prompt-prefix 放置方式、稳定请求分隔符和提示词封套。transcript 与 UI 消费方通过 `source` 区分直接用户消息和注入上下文，无需从合并后的模型内容中恢复隐藏的直接提示词字段。
+
+## 注入生命周期
+
+轮次打开时，`inject()` 将上下文暂存在 loop outbox 中。agent loop 会在安全的步骤边界排空 outbox，同时保持工具协议要求的相邻关系：在助手工具调用批次期间接纳的上下文，只能出现在该批次所有有序结果之后。系统整体取走 outbox，确保同一边界接纳的 steering 和注入上下文对后续同一次请求可见。
+
+没有打开的轮次时，`inject()` 会立即追加对应的 `user/message` 并启动会话刷新。它不会增加轮次编号、发出 `turn/start` 或 `turn/end`、改变 agent 状态，也不会运行模型。同步 API 仍会在异步刷新完成前返回；`whenIdle()` 和 agent dispose（资源释放）会把尚未结束的空闲注入刷新纳入静止边界。
+
+空闲刷新失败时不存在合法的轮次或步骤坐标。系统通过日志或持久化所属的错误接口报告该失败，而不是为不存在的轮次伪造 `agent/error` 载荷。内存中的事件仍已接纳，后续刷新可以重试持久化。
+
+因此，会话不变量允许 `user/message` 位于两个轮次之间，同时继续要求执行事件、steering、助手输出、工具事件以及默认的包扩展事件均受轮次边界约束。持久化、恢复、resume、fork、压缩和查询逻辑必须把合法的轮次外 `user/message` 当作已提交会话历史，而不是中断轮次或可丢弃的日志尾部。
+
+## 扩展点与调用方语义
+
+`PromptDecision.content` 仍只替换直接提示词。`PromptDecision.additionalContexts` 和工具结果的 `additionalContexts` 保留 FIFO 顺序及各自来源，但不再选择放置方式。waterfall（瀑布式事件）监听器调用 `next()` 委托时，必须保留下游返回的提示词内容和额外上下文，除非它有意返回替代值。
+
+调用方主动注入与钩子产生的额外上下文具有不同的准入归属。钩子的额外上下文只会在该钩子允许提示词或工具结果后落入日志。调用方执行 `inject(context)` 后再执行 `send(prompt)` 时，上下文已独立提交；后续提示词准入即使阻止该提示词，注入上下文仍保留在历史中。需要领域级全有或全无语义的调用方，必须在执行任一操作前自行完成准备，或提供领域专用的准入 seam。
+
+跨会话引用使用普通组合方式：宿主先准备快照，以会话引用来源调用 `inject()`，再发送或 steer 可读的直接提示词。目标日志包含两条简单消息，因此来源会话后续变化不会改变回放，transcript 消费方也不需要提示词封套。本提案取代[跨会话引用决策](../../implemented/feature/2026-07-21-cross-session-references.md)中的附件机制，但保留其快照与信任边界规则。
+
+本提案保留[移除注入内容封套](../../implemented/simplification/2026-07-20-unwrap-injected-content-envelopes.md)确立的调用方自主管理框架原则，以及[一次 send、一个轮次](../../implemented/simplification/2026-07-17-one-send-one-turn.md)确立的单条目轮次规则；同时收窄[轮次封闭决策](../../implemented/architecture/2026-06-15-turn-enclosure-invariant.md)，使轮次约束执行过程，而不是约束所有会话事件。
+
+## 曾考虑的替代方案
+
+**保留 `SendOptions.contexts` 作为原子附件。** 提示词准入阻止消息时，这种方式能保留全有或全无交付，但也会让上下文继续成为收件箱生命周期状态的一部分，并迫使每次队列转换和观察事件携带它。大多数调用方都可以通过先注入上下文、再交付消息来表达需求，通用 agent API 不应内置领域事务。
+
+**保留独立的 `context/message` 会话事件。** 独立事件可以缩小轮次外事件的例外范围，但面向模型的 user-role 输入会再次拥有两个投影完全相同的事件类型。`user/message.source` 已能为策略、transcript 和回放消费方提供所需区分。
+
+**为空闲注入保留一次性轮次。** 这种方式能保留通用轮次封闭和方便的刷新边界，却会让轮次计数与轮次观察方报告从未运行模型的工作。持久性是独立的会话关注点，无需伪造执行即可等待。
+
+**保留 `prompt-prefix` 可选放置方式。** 前缀烘焙可以让上下文和请求位于同一条提供方消息中，但它会引入直接提示词的第二种表示，并把放置处理扩散到准入、steering、日志、回放和 UI 代码。需要文本框架的生产方可以直接把它写入自身上下文内容。
+
+**让钩子直接调用 `inject()`，而不是返回额外上下文。** 直接注入会破坏扩展点的准入归属：下游监听器阻止操作之前，上游监听器就可能已经追加上下文。返回 `additionalContexts` 能维持 waterfall 结果的最终权威性，同时复用准入后的 outbox 路径。
+
+## 验收标准
+
+- `SendOptions` 与 steering 收件箱记录不再包含附加上下文；`agent/queued` 只报告保留的消息和 steering 事实。
+- `AdditionalContext` 在提示词拦截、工具执行、hook bridge、guard 和上下文生产方中取代 `HookContext`，且只包含 `content` 与 `source`。
+- 公共类型、持久事件、投影和 UI 回放中均不存在 prompt-prefix 放置方式、提示词封套与 `context/message`。
+- 空闲 `inject()` 在不产生轮次或模型调用的情况下，追加并刷新一条带来源的 `user/message`；`whenIdle()` 和 dispose 会等待该刷新。
+- 活跃轮次注入和钩子产生的上下文会在完整工具结果批次之后的安全边界排空，并在消费它们的请求之前进入日志。
+- 被提示词准入阻止的消息不会打开轮次，也不会追加提示词或钩子产生的额外上下文；调用方此前独立注入的上下文仍保留。
+- 单元测试、持久化与 resume 测试、不变量测试、ACP/TUI 回放测试，以及无需密钥的组装应用快照覆盖新的事件顺序和持久性语义。
+
+## 风险
+
+- 允许一个表层事件位于轮次之外，会削弱一条简单不变量，并可能暴露持久化扫描、崩溃恢复、fork、压缩和会话查询中的隐含假设。
+- 两条连续的 user-role 消息会取代一条烘焙后的提示词消息；提供方适配器和缓存行为必须接受并保留这一顺序。
+- 如果调用方不能接受独立提交契约，`inject()` 后跟一个被阻止的 `send()` 会留下缺少预期直接提示词的上下文。
+- 同步注入 API 无法返回刷新失败。只记录日志的结构化程度低于 `agent/error`，但仅为此场景增加新的持久化事件也可能产生另一个不必要的 seam。
+- 移除附件、放置方式、元数据、封套和一种持久事件类型，是一次影响面较广的预发布迁移，必须原子更新所有生产方和消费方。

+# Agent Note: 工具执行前输入重写——一致性设计
+
+Status: proposed
+
+[English](2026-06-30-pre-tool-input-rewrite.md) | 中文
+
+## 问题
+
+[拦截 seam Agent Note（agent 决策记录）](../../implemented/feature/2026-06-30-interception-seams.md) 将 `tools/pre-execute` 定义为一道针对执行的允许/拒绝/询问门禁，此时执行的身份标识已受保护、参数已被深度冻结。Claude Code 的 `PreToolUse` 钩子还提供了 `updatedInput`，因此忠实的桥接需要一个显式的重写机制。重写不能是对现有执行对象的可变逃逸口：它必须保持持久化历史、审计记录、展示层与实际执行值之间的一致性。
+
+## 问题本质：执行前参数的三个读取方
+
+在 agent loop（智能体循环）中，工具调用的参数在工具执行之前就已提交到日志并被实时消费方读取：
+
+1. **`assistant/message`** 在工具分发之前追加——它是 `deriveMessages()` 回放时的模型历史来源，因此携带模型自身输出的工具调用参数。
+2. **`tool/call`** 是持久化的审计记录，在 `ctx.tools.execute()` 之前追加。
+3. **面向人类的展示读取 `tool/call.arguments`**：UI 渲染器将这些参数传给 `presentResult`；`dsh-tool-bash` 从中派生卡片标题、rawInput、cwd 以及终端/后台处理方式。
+
+如果只做执行层面的重写，UI 会显示一条命令而实际运行的是另一条，并且结果会对着错误的参数渲染。注册表目前通过以下方式防止这种失败模式：对 `arguments` 做 structured-clone 并深度冻结，将执行身份属性设为不可写，且不暴露任何可替换它们的测试 shim 或监听路径。重写设计必须维护这一受保护的身份边界，而非削弱它。
+
+## 提案
+
+重写是一个「身份标识创建前的一致性事务」。当钩子提供 `updatedInput` 时，有效值必须在注册表构造其不可变的 `ToolExecution` 之前确定，并且必须原子地反映到全部三个读取方：
+
+- `tool/call` 审计事件记录重写后的参数（原始参数保留在一个伴随字段中，作为审计线索——钩子修改了调用，原始参数与生效参数都是值得保留的事实）。
+- 派生历史中的 `assistant/message` 必须与实际执行一致。待评估的选项：就地重写 assistant 消息中的工具调用块（改变模型「看到自己说了什么」），或记录一条单独的修正让下一次请求携带。Claude Code 的模型是让模型看到重写已生效。
+- 展示层（`presentCall`/`presentResult`）读取重写后的参数，使 UI 显示实际运行的内容。
+
+在 `PreToolDecision` 当前的触发点上做扩展是不够的：此时两条持久化记录已经存在，执行身份已受保护。实现必须将相关决策移到日志提交之前，或者增加一个专门的、更早的重写决策点来处理待定的模型调用。agent loop 将生效参数提交到历史和审计之后，再构造普通的不可变执行对象，并照常运行现有的允许/拒绝/询问和工具流水线。
+
+## 曾考虑的替代方案
+
+### 为什么不直接修改执行对象？
+
+允许 pre-execute 监听器赋值 `exec.arguments` 只能提供执行层面的重写，模型历史、审计和展示层不会随之改变。保持身份标识受保护使得这种局部行为不可表达。在一致性事务实现之前，CC/Codex 桥接对 `updatedInput` 记录日志并发出警告，而非声称已兑现；循环分发点的 `TODO(pre-tool-input-rewrite)` 标记了缺失的更早阶段。
+
+## 验收标准
+
+- 请求的重写在 `ToolExecution` 身份标识创建之前解决，并原子地反映到全部三个读取方：`tool/call` 审计记录重写后的参数（原始参数保留在伴随字段中）、派生历史与实际执行一致、展示层渲染重写后的参数。
+- 生效的 `ToolExecution.arguments` 在 pre-policy、守卫、分发、post-policy 和最终观测全程保持深度冻结且不可写；不引入任何可变 shim。
+- CC/Codex 桥接兑现 `updatedInput`，不再记录忠实但降级的警告。
+
+## 风险
+
+- 重写 `assistant/message` 中的工具调用块会改变模型「看到自己说了什么」；是否有提供方在回放时拒绝这种改动，是一个需要通过实验确定的开放问题，必须在决策形状冻结之前解决。
+- 更早的重写阶段改变了 `assistant/message`、`tool/call`、钩子审计事件与执行之间的顺序关系；设计必须固定这一顺序，同时不削弱轮次封闭性或调用/结果邻接性。
+
+## 开放问题
+
+- 重写 `assistant/message` 中的工具调用块是否会破坏某些提供方在回放时的预期？还是单独的修正更安全？
+- 原始参数是否应保留在 `tool/call` 事件（审计）上？如果是，放在什么字段？
+- 重写决策是移到日志提交之前，还是成为一个专门的更早 seam？现有的 pre-tool 允许/拒绝钩子如何避免运行两次？
+- 这与未来的权限 `ask` 流程（用户批准一个被重写的调用）如何交互？

## Problem
The subagent seam ([the seam Agent Note](../../implemented/feature/2026-06-21-subagent-capability-seam.md)) hosts multiple named providers on `ctx.subagents`, and the ACP backend ([the ACP backend Agent Note](../../implemented/feature/2026-06-22-acp-subagent-backend.md)) proved the seam generalizes across a process boundary; its Future-providers section explicitly named the Codex app-server and the Claude Code Agent SDK as mechanically similar siblings. Those two are the engines actually worth delegating to today: a harness turn should be able to hand a self-contained task to a real Claude Code or a real Codex — a separate product with its own model, tools, and sandbox — and get back one final answer, without the parent deployment leaking its secrets into the child or the child's behavior silently depending on whatever `~/.claude` / `~/.codex` state exists on the host machine.

+# Agent Note: Claude Code 与 Codex subagent 后端（向外部编码 agent（智能体）的进程外委派）
+
+Status: proposed
+
+[English](2026-07-07-claude-code-and-codex-subagent-backends.md) | 中文
+
+## 问题
+
+subagent seam（[seam Agent Note（agent 决策记录）](../../implemented/feature/2026-06-21-subagent-capability-seam.md)）在 `ctx.subagents` 上托管多个命名提供方，ACP（Agent Client Protocol）后端（[ACP 后端 Agent Note](../../implemented/feature/2026-06-22-acp-subagent-backend.md)）证明了该 seam 能跨越进程边界泛化；其「未来提供方」一节明确将 Codex app-server 与 Claude Code Agent SDK 列为机械上相似的兄弟。如今真正值得委派的就是这两个引擎：harness 的一个轮次应能把一个自包含任务交给真实的 Claude Code 或真实的 Codex——一个拥有自身模型、工具与沙箱的独立产品——并取回一个最终答案，同时父部署不向子进程泄漏密钥，子进程行为也不静默依赖宿主机上碰巧存在的 `~/.claude` / `~/.codex` 状态。
+
+## 提案
+
+两个兄弟提供方包（package），作为 ACP 后端的结构变体，另加一次提取：
+
+- `@deepseek-ai/dsh-subagent-claude-code`：通过 `@anthropic-ai/claude-agent-sdk` 的 `query()` 驱动一个 Claude Code 子进程（SDK 在父进程中运行，并将其内置的 `claude` CLI（命令行界面）作为子进程 spawn）。提供方名称为 `claude-code`：子进程是 Claude Code 这个*产品*，而非 Anthropic 模型适配器——「claude」保留给未来的 `dsh-llm` 适配器。
+- `@deepseek-ai/dsh-subagent-codex`：spawn `codex app-server`，通过其 JSON-RPC-over-stdio 协议驱动一个 thread/turn，使用包内一个手写的换行 JSON 客户端（约 200–300 行）。
+- `@deepseek-ai/dsh-subagent-process`：纯库（沿用 `subagent-inprocess` 的先例），提取 `dsh-subagent-acp` 已有且两个新后端都需要的内容：凭证环境清洗（`buildChildEnv`）、EOF → SIGTERM → SIGKILL 的 dispose（资源释放）阶梯，以及新的隔离配置目录辅助函数（`mkdtemp` 创建、尽力删除）。ACP 后端迁移到该库上；`bash-local` 的兄弟副本保持不动以限制变更范围。
+
+两个提供方逐字复制 ACP 后端的 seam 姿态：每次 `start` 创建全新子进程、恰好一次提示词往返、所有能力均为 `false`、`inheritsParentContext: false`、忽略 `request.parent`/`request.agentOptions`、`id = SessionId(randomUUID())`，且 `result` 从不 reject——子进程级失败扁平化为 stop reason，原始错误则通过 `onError` spec 回调送到 `ctx.logger`。模型暴露无需新代码：每个提供方各加载一次 `dsh-tool-subagent`，使用不同的 `toolName`（`subagent_claude_code`、`subagent_codex`）。无需新的会话事件——唯一的模型可见产物是工具结果，因此可重建性与 ACP 完全相同。明确边界：会话日志重建模型可见的 transcript（文本记录），而不是工作区变更历史——获准写入的子进程将文件作为日志之外的环境副作用进行修改，与 bash 工具和 ACP 后端现有行为完全一致；回放复现请求，而非磁盘。
+
+## 已验证的接口事实（固定版本）
+
+两个集成面在本提案之前均已针对固定版本进行了验证——阅读类型与打包源码、运行无需密钥的 spike——而非仅依赖厂商文档。固定版本是验证基线，不是运行时契约：后端不执行运行时版本探测（无 `codex --version` 门禁、无 SDK 版本嗅探）。兼容性在开发时强制执行——每次依赖升级都会针对真实加载路径重跑无密钥套件——在运行时则通过大声失败来保障：协议层面的意外通过 `onError` 结算为 `error`，绝不静默异常。
+
+**`@anthropic-ai/claude-agent-sdk` 0.3.202。** `options.env` 会替换子进程环境（不与 `process.env` 合并），恰好满足清洗需求。`settingSources` 默认加载所有文件系统设置——隔离要求显式传入 `[]`。结果子类型为 `success` | `error_during_execution` | `error_max_turns` | `error_max_budget_usd` | `error_max_structured_output_retries`。中止时 SDK 自行逐级加强对 CLI 子进程的终止措施：立即关闭 stdin，约 2 秒后若子进程未退出则发送 SIGTERM（已观察到；无残留进程）——无需自定义 kill 回退。`outputFormat: {type: 'json_schema'}` 和 `agents` 选项已存在，为 seam 的 `outputSchema` 能力和命名 subagent 类型提供了未来着陆点；两者均不在本 Agent Note 范围内。
+
+**codex CLI 0.142.5，`codex app-server`（v2 词汇）。** LF 分隔的 JSON，JSON-RPC 2.0 形状但省略 `"jsonrpc"` 头。
+
+- 生命周期：`initialize{clientInfo}` + `initialized` → `thread/start`（接受 `cwd`、`model`、`sandbox`、`approvalPolicy`、`ephemeral`；未认证即可成功）→ `turn/start{threadId, input:[{type:'text',text}]}` 立即返回一个 `inProgress` 的轮次；终止信号是携带 `Turn{status: completed|interrupted|failed|inProgress, error}` 的 `turn/completed` 通知。
+- 审批是服务端发起的请求——`item/commandExecution/requestApproval`、`item/fileChange/requestApproval`、`item/permissions/requestApproval`、`item/tool/requestUserInput`、`mcpServer/elicitation/request`——以 `accept`/`decline` 系列决策应答。
+- 认证：`account/login/start{type:'apiKey', apiKey}` 是一等 RPC，`account/read` 报告 `requiresOpenaiAuth`——且未认证的 `turn/start` 不会快速失败（它会挂在重试中），因此后端必须预检认证状态，并在失败时大声结算为 `error`，而非等待轮次。
+- 隔离：`CODEX_HOME` 重定向被尊重（`initialize` 响应会回显它，测试可据此断言隔离），`ephemeral: true` 的 thread 不留任何会话文件。
+
+## 隔离与凭证
+
+部署只使用 API key 认证，子进程不得看到宿主用户的 Claude Code / Codex 配置：行为必须只由 `cordis.yml` 决定。每次运行获得一个全新的 `mkdtemp` 配置目录——Claude Code 使用 `CLAUDE_CONFIG_DIR`（并显式设置 `settingSources: []`），Codex 使用 `CODEX_HOME`——dispose 时尽力删除；配置字段也可以固定一个持久目录。子进程环境通过提取逐字复用 ACP 后端的 `buildChildEnv` 语义：转发环境变量，但移除凭证形态的变量（`/KEY|SECRET|TOKEN/i`），再叠加 `config.env`——因此 `PATH`、`HOME`、`TMPDIR`、locale 和代理变量保留，CLI 正常运行；只有环境中的凭证形态变量被清洗（Claude Code 的 `ANTHROPIC_API_KEY` 通过 `config.env` 显式进入），Codex key 则通过 `account/login/start` RPC 进入隔离的 `CODEX_HOME`，而非手写 `auth.json`。
+
+## 权限与审批策略
+
+每个后端不压缩为 ACP 单一的 `permission: allow|reject` 旋钮，而把引擎原生词汇作为配置暴露，并采用保守默认值：Claude Code 获得 `permissionMode`（默认 `default`）以及 `permission: allow|reject`（默认 `reject`），后者作为所有漏过请求的 `canUseTool` 自动应答；Codex 获得 `sandboxMode`（默认 `read-only`）和 `approvalPolicy`（默认 `never`），以及同一个 `permission` 后备值，用来应答仍然到达的审批请求。默认值刻意做到不造成损害（开箱即用的子进程无法写文件）；示例演示如何开放权限（`acceptEdits` / `workspace-write`）。机械规则是：每一个服务端发起的请求都由程序迅速结算——枚举出的审批/用户输入/elicitation 请求按配置策略应答，未知请求方法用 JSON-RPC method-not-found 错误响应（绝不保持 pending），未知通知被消费——因此任何子进程请求都不会因等待永远不会到来的应答而卡住轮次。这一版中提示词不会到达人类，与 ACP 一致。
+
+## StopReason 映射
+
+Claude Code：`success` → `completed`；`error_max_turns`、`error_during_execution`、`error_max_budget_usd`、`error_max_structured_output_retries` → `error`（与 ACP 对 `max_turn_requests` 的处理对齐：未完成的任务不是成功）；生成器中止 → `aborted`；未知值 → `error`。Codex：`Turn.status` 为 `completed` → `completed`；`interrupted` → `aborted`；`failed` 且 `codexErrorInfo: 'contextWindowExceeded'` → `max-tokens`，其他 `failed` → `error`；传输/spawn/认证预检失败 → `error`（若已请求取消则为 `aborted`）。两者中，`cancel()` 采用 ACP 形状：标志位 + abort/interrupt + 一个 cancel-settled 竞争分支，使不合作的子进程无法阻塞结果。
+
+活性姿态，明确声明：teardown 时序是配置项，轮次时长不是。两个后端将 dispose 阶梯的宽限期作为带默认值的已验证配置字段（ACP 后端的 `disposeEofGraceMs`/`disposeGraceMs` 形状，由提取库承载），但刻意不设轮次时长或启动超时——与 ACP 一致：轮次期间的活性由调用方通过 `cancel()`/abort signal 掌控，subagent 轮次持续数分钟也属合理，而 Codex 认证预检消除了唯一已验证的必然挂起场景；需要墙钟上限的部署从父侧取消即可。
+
+## 测试
+
+依照根 AGENTS.md 规则在每个层级明确命名，并预先消除风险：
+
+- **无密钥单元/集成测试**：每个后端都镜像 ACP spec 清单（往返和输出累积、每种 stop 映射、两条取消路径、已中止、两种策略下的权限自动应答、未知消息容错、错误命令的 spawn 失败、HMR（热模块替换）提供方清理、导出形状、子进程环境隔离断言和临时目录删除；Codex 另加认证预检失败路径）。Claude Code harness 是通过 `pathToClaudeCodeExecutable` 接入真实 SDK 的脚本化假 `claude` 可执行文件——一个 spike 已在 24ms 内完成端到端无密钥验证（假 CLI 应答一次 `control_request/initialize`，并讲 plain stream-json，约 40 行）。Codex harness 是讲已验证协议格式的脚本化 mock app-server 子进程，沿用 `mock-acp-server.ts` 形状。
+- **有密钥 e2e 测试**：每个后端的真实引擎执行并由磁盘验证真实文件工作，固定使用开放后的配置，以免验收与不造成损害的默认值冲突——Claude Code 使用 `permissionMode: 'acceptEdits'`，Codex 使用 `sandboxMode: 'workspace-write'` + `approvalPolicy: 'never'`；自跳过会准确报告缺失的是二进制还是 key。CI 没有密钥，因此依照有密钥策略在本地运行。
+- **快照测试**：以 `TODO(claude-code-subagent-replay)` / `TODO(codex-subagent-replay)` 推迟——即 ACP 后端也推迟的独立回放形状（[按会话回放 Agent Note](../../implemented/testing/2026-06-22-subagent-snapshot-replay.md)）；在此期间由无密钥套件提供确定性覆盖。
+
+## 曾考虑的替代方案
+
+### 为什么不用官方 `@openai/codex-sdk` 而手写客户端？
+
+dispose 阶梯和环境清洗要求拥有子进程（spawn 参数、env、信号、exit 等待）；SDK 隐藏了进程。协议格式（wire format）极其简单（LF JSON），形状可按固定版本生成（`codex app-server generate-json-schema`），仓库先例（`hook-protocol`）是拥有薄协议核心而非包装他人的运行时。SDK 能节省协议演进的维护成本，但代价是失去本后端存在的意义所在的精确控制。
+
+### 为什么不用模型可见的 `subagent_type` 参数（单一 Task 风格工具）？
+
+Claude Code 自身的 Task 工具将 subagent 类型放在模型可见的 schema 中，选择一个提示词 + 工具集人格。这里的选择是在执行引擎之间做出的，而只有部署者知道哪些引擎配置了凭证——因此选择留在部署配置层，保持 `dsh-tool-subagent` 文档中的「一个提供方对应一个工具」契约。人格风格的类型选择器应是针对工具的另一个 Agent Note，而非针对后端。
+
+### 为什么不用登录态凭证和用户自身的配置？
+
+继承 `~/.claude` / `~/.codex`（订阅登录、用户设置、skill（技能）、MCP 服务器）会使子进程行为依赖宿主机状态，并在 ACP 后端和 bash 执行器确立的「凭证通过 `config.env` 显式进入，绝不隐式继承」规则上打开一个隐式例外。仅 API key 加强制配置目录隔离使运行可复现；需要共享状态的部署可以有意将配置目录字段指向一个持久目录。
+
+### 为什么不为 Claude Code 无密钥测试注入驱动层 seam？
+
+注入假的 `query()` 会 mock 我们自己的边界，使真实 SDK 加载路径未被测试（docs/testing.md 中的 real-over-mock 策略）。曾考虑此方案的风险——SDK↔CLI 的 stream-json 控制协议是内部实现——已被 spike 消除：假 CLI harness 今天能对真实固定版本的 SDK 正常工作。如果 SDK 升级破坏了 mock，无密钥套件会让升级 PR（Pull Request）失败，这正是门禁在发挥作用。
+
+### 为什么不用 ACP 适配器（如 `claude-code-acp`）复用既有后端？
+
+社区 shim 将两个引擎包装为 ACP，这会使它们在 `dsh-subagent-acp` 上变成「仅配置」。但这在 harness 与引擎之间插入了一个非官方的第三方层，抹去了本 Agent Note 暴露的原生控制面（permissionMode、sandboxMode/approvalPolicy、配置目录隔离、apiKey RPC），并以 shim 的发布节奏替换了第一方协议的稳定性。第一方接口——Agent SDK 和 app-server——才是受支持的集成点。
+
+## 验收标准
+
+在两个引擎和密钥均已配置的机器上：一个 REPL 驱动的模型通过 `subagent_claude_code` 完成一个真实文件任务，通过 `subagent_codex` 完成另一个，工具结果为子进程的最终答案，父会话日志中仅有 `tool/call` + `tool/result`。无密钥套件在无凭证环境下以逐文件 100% 覆盖率通过，断言隔离（清洗后的子进程环境、dispose 后无残留临时配置目录），并断言 `~/.claude` / `~/.codex` 的存在与否不影响子进程行为。取消父轮次后，两个后端在有界时间内完全停稳，无残留子进程。e2e 套件干净地自跳过，命名缺失的前置条件。
+
+## 风险
+
+- `codex app-server` 被 CLI 标记为实验性，其 v1/v2 词汇共存；客户端固定 0.142.5、仅实现 v2、对未知方法/通知消费而不崩溃，但未来 codex 升级仍可能迫使返工（每次升级重新生成 schema 并重跑无密钥套件——这是上述「不做运行时版本探测」立场背后的开发时强制执行）。
+- Claude Code 假 CLI mock 依赖一个内部协议：任何 SDK 升级都必须通过无密钥套件，控制协议的破坏性变更意味着返工 mock（回退方案：上面否决的驱动注入 seam 成为逃生舱口）。
+- SDK 的 optionalDependencies 每平台约 280MB——已接受，限制在单个后端包内。
+- SDK 的 SIGKILL 分支（EOF→SIGTERM 之后）未被观察到，信任其实现；e2e 保留无残留进程断言。
+- Codex 是部署前置条件（无 npm 内置二进制）；缺失或不兼容的二进制以大声的 spawn/协议 `error` 呈现，而非版本探测。
+- 每次运行付出一个全新子进程的代价，且仅最终答案浮出——思考、工具卡片和用量被消费后丢弃；连接池、中间进度浮出、`sendMessage`/`resume`、通过 SDK 的 `outputFormat` 实现 `outputSchema`、以及通过 SDK 的 `agents` 选项实现命名 subagent 类型，均为刻意推迟。

## Problem
A user may want to explore a question from a live session without changing its main context. Existing primitives do not expose that product shape: [session-store fork](../../implemented/feature/2026-06-30-session-store-fork-api.md) creates an unattached session, while [fork subagents](../../implemented/feature/2026-06-21-subagent-capability-seam.md) are model-driven tasks whose transcript collapses into one tool result. Neither gives the user a separate conversation, and neither records a conclusion back into the parent with provenance.

+# Agent Note: 交互式侧会话与合并回写
+
+Status: proposed
+
+[English](2026-07-08-interactive-side-sessions.md) | 中文
+
+## 问题
+
+用户可能希望在不改变当前会话主上下文的前提下，探索一个来自活跃会话的问题。现有原语无法提供这种产品形态：[会话存储 fork](../../implemented/feature/2026-06-30-session-store-fork-api.md)创建的是一个无关联的会话，而 [fork subagent](../../implemented/feature/2026-06-21-subagent-capability-seam.md)是模型驱动的任务，其 transcript（文本记录）会折叠为一条工具结果。两者都不能给用户一个独立的对话，也都不能将结论带着出处信息记录回父会话。
+
+## 提案
+
+**侧会话（side session）** 是一个普通的活跃会话，从源会话的最后一个已完成轮次 fork 而来，绑定到自己的 agent（智能体），定位为只读顾问，并能**合并回写**一条精简笔记。
+
+- **Fork 并绑定：** 以父会话的平衡已完成轮次前缀创建子会话，并在其元数据中标记 `parentSession` 与 `seedLength`。这组合了 `ctx.agents.create({ seed, meta })`；不新增核心服务或会话存储方法。
+- **顾问定位：** 创建后注入一条插件来源的 `context/message`，告知子会话只做解释，不执行变更或继续任务。保持系统提示词逐字节一致，可在继承的历史上保留提供方的前缀缓存。
+- **合并回写：** 向子会话请求一条有长度上限的 handback，然后向父会话注入一条插件来源的 `context/message`。父会话的下一次请求在其日志位置看到该消息，保持回放与[请求可重建性](../../implemented/architecture/2026-07-05-reconstructable-requests.md)，无需新增会话事件。
+- **呈现：** 调用方式、会话切换与 handback 渲染属于首个客户端拥有的界面。本 Agent Note（agent 决策记录）仅规定与界面无关的机制。
+
+回退产品化、会话树视图、面向模型的侧会话工具，以及 `forkName`/`mergedInto` 元数据均不在本 Agent Note 范围内。一次真实适配器 spike 已验证了源日志隔离、继承上下文、多轮子会话交互，以及合并回写在父会话下一轮次中的可见性。
+
+## 曾考虑的替代方案
+
+- **使用 subagent seam：** 否决。侧会话是用户驱动的、客户端可见的，且可能存活超过父会话的一个轮次；subagent 是模型驱动的运行，返回一条工具结果。
+- **修改子会话的系统提示词：** 默认否决，因为任何字节变化都会从第零个 token 起使前缀缓存失效。部署方仍可选择这种更强的隔离方式。
+- **新增 `sidechat/*` 事件：** 延后。插件来源的 `context/message` 已提供持久性、出处与回放能力；只有当某个界面需要差异化渲染时，专用事件才有正当理由。
+- **现在就绑定一个协议界面：** 否决。当前 UI 由客户端拥有。实时呈现最终必须从持久消息派生，以使回放渲染出相同的记录。
+
+## 验收标准
+
+- Fork 不改变源会话，创建的子会话具有平衡的已完成轮次前缀、`parentSession`、`seedLength`，以及逐字节一致的系统提示词。
+- 顾问定位在子会话追加历史的头部恰好添加一条插件来源的 `context/message`，而非修改其系统提示词。
+- 合并回写恰好添加一条有长度上限的 `context/message`，来源为 `plugin: sidechat`；父会话的下一次请求与回放在相同位置看到它。
+- 父会话与子会话并发运行，日志和流之间无串扰。
+- 单元测试覆盖 fork/attach 与合并回写；快照覆盖率随首个绑定界面一起落地。
+
+## 风险
+
+- 只读行为在 `tools/pre-execute` 拒绝门禁强制执行之前仅为建议性质；[拦截 seam](../../implemented/feature/2026-06-30-interception-seams.md) 可在不改变本机制的前提下添加该门禁。
+- 经过压缩（compaction）的源会话 fork 出的是其压缩视图，因此绑定的界面应当告知用户子会话继承的是摘要而非被替换的轮次。
+- 反复的 handback 会消耗父会话上下文。每次合并的长度上限约束了单条笔记的大小；后续的合并整理属于上下文压缩的职责。

+# Agent Note: API extractor 报告
+
+Status: proposed
+
+[English](2026-06-11-api-extractor-reports.md) | 中文
+
+> 从最初的「doc-sync（文档同步门禁）与 API 报告」Agent Note（agent 决策记录）中拆出（首次提出于 2026-06-11）。第 1 至第 2 部分（文档块类型检查、事件分类体系校验）已交付，见 [doc-sync 强制](../../implemented/process/2026-06-11-doc-sync-enforcement.md)。本文是被推迟的第 3 部分，作为独立提案保留。
+
+## 问题
+
+公开 API 的变更是不可见的：没有任何机制将「此次提交改变了公开接口」变为一个显式、可评审的事实。评审者阅读 diff 时可能遗漏某个导出类型新增了字段，或某个方法签名发生了变化。
+
+## 提案
+
+使用 api-extractor（或 `tsc --emitDeclarationOnly` 加一份规范化的公开接口导出）为每个包（package）生成一份签入仓库的 `etc/<pkg>.api.md`；CI 在重新生成结果与已签入报告不一致时失败。这样，每一次公开 API 变更都会成为评审者（或评审 agent（智能体））必须看到的一行 diff。
+
+## 曾考虑的替代方案
+
+**`tsc --emitDeclarationOnly` 加规范化的公开接口导出**：如果 api-extractor 过于笨重，这是更轻量的机制；两者都能满足提案所需的「签入仓库、可 diff」的报告形态。
+
+## 验收标准
+
+- 每个包都有一份签入仓库的 `etc/<pkg>.api.md`；CI 在重新生成结果与已提交报告不一致时失败。
+- 公开 API 变更（新增导出、字段放宽、签名变化）在评审中以报告 diff 行的形式可见。
+
+## 风险
+
+该依赖笨重且难以调教（这正是它被推迟的原因），且报告格式会随编译器升级而变动，增加一个维护面；在各包尚未发布的阶段，收益有限。
+
+## 推迟原因
+
+在 doc-sync 落地时被推迟：对于一个内部 monorepo，评审者已经能看到源码 diff，价值不高；且依赖笨重、难以调教。如果各包将来对外发布，再重新评估——届时一份稳定、可 diff 的公开接口报告才值得其维护成本。

## Problem
Two architectural guarantees currently live only in prose: (1) nothing depends on the concrete loop package ([the microkernel promise](../../implemented/architecture/2026-06-11-microkernel-event-taxonomy.md)), and (2) every LlmAdapter speaks the chunk protocol correctly. Both should be mechanical ([the quality-gates principle](../../implemented/process/2026-06-11-quality-gates.md)).

+# Agent Note: 架构一致性——依赖规则与适配器套件
+
+Status: proposed
+
+[English](2026-06-11-architectural-conformance.md) | 中文
+
+## 问题
+
+目前有两项架构保证仅存在于行文中：（1）没有任何组件依赖具体的 loop 包（package）（[微内核承诺](../../implemented/architecture/2026-06-11-microkernel-event-taxonomy.md)）；（2）每个 LlmAdapter 都正确遵循分片协议。二者都应由机制强制执行（[质量门禁原则](../../implemented/process/2026-06-11-quality-gates.md)）。
+
+## 提案
+
+**dependency-cruiser** 配合以下规则：
+
+- `packages/*`（除 agent-loop（智能体循环）自身的 tests 和 examples/ 外）禁止导入 `@deepseek-ai/dsh-agent-loop`。
+- 禁止跨包深层导入（`@deepseek-ai/dsh-*/src/...` 路径）——只允许使用公开入口点。
+- packages/ 内禁止导入循环。
+- `vendor/*` 禁止从 `packages/*` 导入。
+- 分层：dsh-llm 不导入其他 dsh 包；dsh-session 仅导入 dsh-llm；以此类推（packages/README.md 中的依赖表，强制执行）。
+
+**适配器一致性套件**位于 dsh-llm（`@deepseek-ai/dsh-llm/conformance`）：一个以适配器工厂为参数的可复用 vitest 套件，用于断言分片协议契约，包括每个块内的索引单调递增、某个索引出现 `block-end` 后不再接收增量、恰好出现一个 `finish`、用量至多出现一次、每个 `tool-call-delta` 都携带调用 id，并且及时响应 abort。当前先对 mock 运行；DeepSeek V4 适配器从第一天起继承该套件。还可以选择提供开发模式下的 `strictAdapter()` 包装层，在调试标志开启时于运行时强制执行相同规则（与 [开发模式不变式](../../implemented/architecture/2026-06-11-dev-invariants-over-deep-readonly.md) 配对）。
+
+## 计划
+
+先落地 dependency-cruiser 配置与 CI 步骤（约一小时工作量，换来永久保证）；一致性套件随其首个消费方测试（针对 MockAdapter）一起落地，并作为 V4 适配器阶段的前置条件。
+
+## 验收标准
+
+- dependency-cruiser 在 CI 中运行上述规则族；违规导入导致构建失败。
+- 一致性套件对 mock 适配器和两个正式适配器运行，新适配器包通过调用该套件并传入自己的工厂即可继承测试。
+
+## 风险
+
+随着包的增加，dep-cruiser 规则需要维护——规则应基于模式（`dsh-*`）而非逐一枚举。

## Problem
The vendor manifest ([the vendoring decision](../../implemented/process/2026-06-11-vendor-cordis-as-source.md)) is enforced at commit time in the *forward* direction (vendored change ⇒ manifest update) but nothing verifies the manifest's *claims*: that vendor/ actually equals upstream-at-SHA plus exactly the logged modifications. And the handful of true npm dependencies have no advisory monitoring or update cadence.

+# Agent Note: 供应链检查与 vendor 漂移验证
+
+Status: proposed
+
+[English](2026-06-11-supply-chain-and-vendor-drift.md) | 中文
+
+## 问题
+
+vendor manifest（元数据清单）（见[引入 vendor 的决策](../../implemented/process/2026-06-11-vendor-cordis-as-source.md)）在提交时仅在*正向*强制执行（vendor 变更 ⇒ manifest 更新），但没有任何机制验证 manifest 的*声明*：即 vendor/ 确实等于上游指定 SHA 的内容加上所记录的修改。此外，少量真正的 npm 依赖也没有安全公告监控或更新节奏。
+
+## 提案
+
+1. **Vendor 漂移检查**（夜间 CI）：以 manifest 中记录的 SHA 浅克隆上游仓库，复制对应的包（package）源码，与 `vendor/*/src` 做 diff。除非 diff 与已记录的本地修改一致（每项修改以签入的 patch 文件保存——日志条目从行文描述变为可验证的产物），否则任务失败。
+2. **依赖安全公告**：对 lockfile 运行 osv-scanner（或 `pnpm audit`），按计划定期执行，并在涉及 lockfile 变更的 PR（Pull Request）上触发。
+3. **许可证清单**：一个脚本断言每个 vendor 包都携带其 LICENSE 文件，且 package.json 的 `license` 字段与 vendor/README.md 中的清单一致（我们混合了 vendor 的 MIT 与自有的 BSD-3）——作为 CI 步骤运行。
+4. **Renovate**（或定时 agent（智能体）任务）以小 PR 的形式提议 npm 依赖更新，这些 PR 走完整门禁套件；vendor 包不在其列（它们的更新遵循 manifest 同步流程，理想情况下是半自动化的 agent 工作流：拉取上游、重新应用 patch、运行门禁、以更新后的 manifest 表格开 PR）。
+
+## 计划
+
+第 3 项最简单，先做。第 1 项需要 CI 能通过网络访问上游仓库（私有仓库，需要 token），并将现有两项已记录的修改转换为 patch 文件。第 2 项和第 4 项是配置工作。
+
+## 曾考虑的替代方案
+
+- **用 `pnpm audit` 替代 osv-scanner**：两者都满足安全公告扫描的需求；具体选择推迟到实现阶段决定。
+- **用定时 agent 任务替代 Renovate**：在提议小型更新 PR 并走完整门禁套件方面效果等价；vendor 包无论哪种方案都不在其列（它们的更新遵循 manifest 同步流程）。
+
+## 验收标准
+
+- 许可证清单脚本在 CI 中运行，缺少 LICENSE 或 `license` 字段与 `vendor/README.md` 中的清单矛盾时失败。
+- 夜间漂移任务从 manifest SHA 加签入的 patch 文件重建 `vendor/`，出现任何无法解释的 diff 时失败。
+- 安全公告扫描按计划定期运行，并在涉及 lockfile 变更的 PR 上运行。
+
+## 风险
+
+上游仓库是私有镜像；CI 凭证与可用性是漂移检查的主要阻力。如果受阻，可改为本地定时 agent 任务而非 CI。

## Problem
Package and gate inventories are repeated across TypeScript project references, package docs, CI prose, and Knip overrides. Most restate package layout, manifest data, or aggregate command contents. Each new package therefore creates avoidable synchronization points.

+# Agent Note: 通过发现机制获取包清单，而非维护静态列表
+
+Status: proposed
+
+[English](2026-06-20-discover-package-inventory.md) | 中文
+
+## 问题
+
+包（package）与门禁清单在 TypeScript project references、包文档、CI 描述和 Knip 覆盖项中反复出现。大多数只是重述包布局、manifest（元数据清单）数据或聚合命令内容。因此每新增一个包都会产生本可避免的同步点。
+
+[包层级结构](../../implemented/architecture/2026-06-20-package-hierarchy.md)已经手动消除了其中若干：`scripts/publint-all.ts` 现在从 `packages/<group>/<pkg>` 布局推导列表，两份 `tsconfig` 的 `paths` 映射也合并为一个 `@deepseek-ai/dsh-*` 通配符。剩下的是无法用 glob 消除的清单，主要是聚合配置（`tsconfig.host.json`、`tsconfig.client.json`）的 project `references`——TypeScript 要求它们是显式数组（没有通配符形式）。
+
+当静态列表编码的是策略时，它们是合理的；当它们只是重复 `package.json`、workspace glob 或包层级结构中已有的 manifest 数据或布局事实时，就是不必要的摩擦。
+
+## 提案
+
+让剩余的包与门禁清单可被发现。一个唯一的权威来源，即 `packages/<group>/<pkg>` 层级结构加上包 manifest，应当驱动聚合配置的 `references`、模块图以及任何全量包列表，并配合一个生成加校验步骤（沿用现有的 `gen-module-graph` / `gen-cordis-catalog` 模式：生成器写出产物，`--check` 模式在 `hygiene` / `doc-sync`（文档同步门禁）中发现已提交副本陈旧时失败）。模块图生成已经在读取包 manifest。`doc-sync` 应当成为定义并打印其子门禁的唯一命令，文档链接到该命令，而非重述第二份列表。
+
+层级结构不需要编码关于包的所有事实，但应当编码宽泛的维护策略：core/product 包、集成包、能力 seam 包与 support/test/example 包不应在脚本能区分它们之前先要求一份手工维护的例外列表。
+
+有一项已编目的内容根本不需要生成器：将 e2e 入口 glob 折入 Knip 的默认配置段，即可直接删除逐包的重复声明。
+
+## 验收标准
+
+- 聚合配置的 project `references` 由层级结构生成（生成器输出它们；`--check` 门禁在提交副本陈旧时报错），而非手工维护。
+- 新增一个包时，不需要为任何门禁编辑静态包列表。
+- 文档描述真源，而非重复生成的清单。
+- CI 调用聚合命令，由这些命令自行管理其子门禁列表。
+- `knip.json` 仅在编码真实信息（额外入口文件、被忽略的依赖）时才携带逐包覆盖项，绝不重述默认配置段。
+
+## 风险
+
+发现脚本可能变得过于精巧。实现应当保持朴素：读取 manifest、按显式字段过滤、打印解析后的列表，并在出错时明确失败。收益在于消除手工清单的漂移，而非发明一套构建系统。

Several package-root exports, result fields, and convenience methods have no production consumer.

+# Agent Note: 裁剪无用的公开与结果接口
+
+Status: proposed
+
+[English](2026-07-04-prune-dead-core-spine-surface.md) | 中文
+
+## 问题
+
+若干包（package）根导出、结果字段和便利方法没有生产消费方。它们之所以存活，要么是因为测试通过公开入口导入了内部实现，要么是因为某个类型预期了一个从未出现的调用者。每一项单独看都很小，但合在一起，它们扩大了 SDK 契约、生成的 catalog、文档和回归矩阵，却没有支撑任何已交付的路径。
+
+生产语料库是 `packages/*/*/src`、示例源码/配置和运行时脚本。测试、包 README 和 Agent Note（agent 决策记录）行文是发布的证据，但不是固定调用者。`cordis_inspect` 使 `packages/cordis/tool-cordis/src/api-catalog.ts` 对模型可见，`cordis_mount` 可以通过受保护的真实服务代理调用注入的服务，因此 catalog 中的服务方法和返回形状是真正的动态产品接口。下表因此区分「没有固定的仓库调用者」与「不可达」：涉及 catalog 词汇的行有意收缩模型编写的 mount 能发现和调用的内容，而包根实现辅助函数并不通过该服务门面可达。精确符号搜索得出以下清单：
+
+| 接口 | 生产证据 | 简化方式 |
+| --- | --- | --- |
+| `SurfaceManager.invalidate()` | 只有其单元测试调用它；seeding 在惰性创建的 manager 存在之前就已完成，且会话从不替换其日志引用。 | 删除它及其不可能触发的整体替换契约。 |
+| `ToolExecutionResult.callId` | 每个钩子已经接收不可变的 `ToolExecution`；循环和 ACP（Agent Client Protocol）通过调用/会话事件关联。没有消费方读取这个重复的结果字段。 | 移除该字段、复制/不匹配守卫，以及证明该重复不可能不一致的测试。 |
+| `ReactLoopAgent` 根导出 | 包外的命名导入都是测试；生产代码面向 `Agent` 编程，通过 `ctx.agents` 创建/恢复。 | 返回/接口类型为 `Agent`，将具体循环类改为包内部；保留有意设计的同步、仅配置的 `AgentLoop.create()` 路径。 |
+| `workflow-workerthread` 的 protocol/runtime/session 再导出与命名的 `WorkerWorkflowEngine` | 每个包名消费方都使用默认引擎；工作流 Agent Note 已将 worker 协议格式（wire format）定义为私有。 | 保留默认插件类/配置契约；移除重复的命名类导出，将协议模块保持为源码私有。 |
+| `code-runtime-worker` 的 protocol/bootstrap 再导出 | 包外的生产/e2e 消费方使用 `WorkerCodeRuntime` 和配置，而非 `BootstrapPort`、`PatchableStream` 或 worker 消息/启动类型。 | 保留运行时类/配置契约，将其协议格式/bootstrap 词汇改为源码私有。 |
+| ACP 的 `agentOptions` 根导出 | 该辅助函数只有同文件和 ACP 测试消费方；唯一的包外生产消费方挂载的是插件命名空间。 | 保留 `name`、`inject`、`Config`、`AcpConfig` 和 `apply`；将 `agentOptions` 改为源码私有，通过桥接层行为测试。 |
+| `providerWording` 与 `completedTurnPrefix` 根导出 | 各有一个同包生产调用者；只有 balanced-prefix 辅助函数有一个同包白盒测试。 | 改为源码私有，测试提供方行为。 |
+| `depthOf`、`SubagentDepthError`、`SENSITIVE_ENV_PATTERN`、`waitForExit` 与 `exitsWithin` 根导出 | 生产 subagent 后端消费的是进程内 runner 和子进程构造/dispose（资源释放）辅助函数，而非这些强制/测试内部实现。 | 保留深度/环境/退出行为，但将辅助函数和 error/regex 改为源码私有；通过 spawn 和 dispose 测试。 |
+| `PersistenceCoordinator.inits`、后端 `inits` 访问器、`seedCoversPrefix` 与 `assertSerializable` | 访问器为白盒测试而存在；`seedCoversPrefix` 没有包外生产导入者；`assertSerializable` 没有生产调用者，且与 coordinator append 边界的无损快照重复。 | 通过 `session/flush` 观察初始化，将 `seedCoversPrefix` 改为源码私有，删除 `assertSerializable`。保留两个后端、`SessionHeader` 和 SQLite 的版本契约。 |
+| `LlmError.status` 与回放 status | 适配器/回放填充它，但生产分支基于稳定的错误码/消息判断，从不读取原始 status。 | 移除未读字段和回放管道，保留错误分类。 |
+| `BlockAssembler.push()` 返回值 | 两个生产调用者都忽略返回的已完成块。 | 返回 `void`；保留有意公开的 `blocks()`/`message()` 契约。 |
+| `compactRegion` 的独立 `session` 参数 | 固定调用者传入的对象与 `agent.session` 上已有的是同一个；模型可见的 mount API 也能调用该方法，但接受两个身份允许挂载的插件提供不一致的配对。 | 保留手动 region seam，同时有意将其收窄为以 `agent.session` 为唯一真源。 |
+| `CompactionResult.startSeq`、`summarySeq`、`endSeq` 与 `summary` | 生产消费方只读取 shadowed range/seq/token 统计；持久日志拥有 summary 和事件标识。 | 移除四个结果回显，保留两个共享的 transcript（文本记录）渲染器。 |
+| `BasicCompactService` 的 estimation/summarization 可见性 | 没有包外生产调用者调用这五个方法；已实现的 Agent Note 只将 `estimateContentTokens()` 和 `summarize()` 命名为子类钩子。 | 将这两个方法改为 `protected`，其余三个编排专用的估算器改为 private。 |
+| `CodeLogEntry.source`/`level` 与 `RunCodeMeta.dispatches` | 每个生产消费方都将日志映射为文本；没有 presenter/模型路径读取其他字段或持久化的 dispatch 计数。 | 将 code-runtime 日志改为字符串（或纯文本条目），移除 result-meta 的 dispatch 管道；保留用于生成确定性 dispatch id 的本地计数器。 |
+| `CodeRuntime.language` 与 `CodeRuntime.isolation` | worker 后端提供唯一的生产值，而 Code Mode 及其他所有生产调用方只调用 `run()`。 | 移除未读描述符，同时保留 worker 的语言、隔离、预算、取消与资源释放行为。 |
+| `ToolNotFoundError.toolName`、`SystemPrompt.config` 与 `BashTask.command` | 每个存储的公开值都没有生产读取者。 | 移除未读字段，保留错误消息、已解析的配置行为和任务生命周期。 |
+| 后端包根实现辅助函数 | 下方精确清单仅通过相对路径的同包导入调用。生产命名空间导入挂载的是保留的插件契约，不读取这些属性；命名根消费方都是测试。 | 保留每个适配器/提供方/服务及其配置/错误契约；停止在包根导出所列辅助函数/常量。 |
+| 消费方包根实现辅助函数 | 下方精确清单只有同包生产调用者。生产命名空间导入挂载的是插件契约，不读取辅助属性；命名根消费方都是测试。 | 保留插件契约和稳定的错误码；将测试迁移到包内模块或公开行为，停止在包根导出所列辅助函数。 |

+
+## 提案
+
+以一次有界的、协调的公开接口清理，移除或降级上述每一行。同步更新包 README、JSDoc、生成的 API/事件 catalog、type-equiv 记录、必要的 exports map 以及测试，使测试通过所属的公开 seam 验证行为，而非保留仅为测试而存在的入口。不折叠任何能力 seam、LLM（大语言模型）适配器、持久化后端或生命周期完全停稳契约。
+
+## 曾考虑的替代方案
+
+**保留测试便利函数和自包含的结果字段为公开。** 公开辅助函数可以让白盒测试更方便，自包含的结果字段看起来更易用，未来的嵌入者可能需要具体循环类或枚举方法。这些好处是假设性的；当前它们让每处实现和文档都要解释没有已交付调用者能观察到的状态。真正的消费方可以引入它所需的最小契约，其所有权和失败语义明确。
+
+**保留所有 catalog 成员以供模型编写的 mount 使用。** 自引用工具集是一条真实的通用消费路径，而非生成文档的噪音。然而，它的价值来自准确、可组合的服务接口，而非无限期保留重复字段或不一致的参数对；上述每一项 catalog 收缩都移除了在同一次执行、同一个 agent（智能体）或同一结果中其他位置已可获得的事实，并在同一变更中更新 API 参考。
+
+## 验收标准
+
+- 精确符号搜索显示：在本 Agent Note 及任何已实现 Agent Note 修正之外，没有被移除的接口。
+- 本 Agent Note 列出的每个接口均按指定方式缺失或降级；清单之外有意保留的扩展/测试契约不变。
+- 工具执行、上下文压缩（context compaction）、两个 LLM 适配器、两个持久化后端、工作流隔离以及 agent 创建/恢复保持其已交付行为。
+- 类型检查、覆盖率、快照、doc-sync（文档同步门禁）、module-graph 校验、构建和 hygiene 通过。
+
+## 风险
+
+大多数移除在编译时可见但对运行时无影响。上下文压缩参数清理有意禁止会话/上下文不匹配，同时保留手动 region seam。外部预发布嵌入者和现有模型编写的 mount 可能导入更少的辅助函数、传递更少的参数或接收更窄的结果形状；这是有意的产品接口收缩，而非仅仅是生成 catalog 的清理。仓库尚未发布，因此承载不受支持的接口才是更大的基础成本。

## Problem
Several loop tests synchronize with `setTimeout(30)` sleeps — flakiness debt that wastes agent cycles on retries and can mask ordering bugs. Separately, our core architectural promise (any session log replays to identical derived history) is asserted in two tests but is cheap to assert *everywhere*. And the inbox wakeup race was verified by hand exactly once; nothing re-verifies it continuously.

+# Agent Note: 确定性测试、回放不变式 fixture（测试前置数据）与竞态压力测试
+
+Status: proposed
+
+[English](2026-06-11-deterministic-and-stress-testing.md) | 中文
+
+## 问题
+
+若干 agent loop（智能体循环）测试通过 `setTimeout(30)` 睡眠来同步——这是一笔不稳定性债务，浪费 agent 的重试周期，还可能掩盖时序 bug。另外，我们的核心架构承诺（任何会话日志回放后都能得到相同的派生历史）目前只在两个测试中断言，但在*所有*测试中断言的成本极低。此外，inbox 唤醒竞态只被手动验证过一次，没有任何机制持续复验。
+
+## 提案
+
+三项措施：
+
+1. **测试中禁止挂钟睡眠。** 将 `setTimeout(N)` 等待替换为事件驱动等待（既有的 `waitForIdle` 模式，扩展为 `waitForStatus`、`waitForEvent(n)`），或在需要测试时间本身时使用 vitest 的 fake timer。通过 lint 规则禁止 `setTimeout`，适用范围是 `packages/*/tests`，白名单辅助模块除外。
+2. **通用回放 fixture。** 一个共享测试辅助函数包装 agent loop harness，使每个测试结束后，agent 的会话日志被回放到一个全新的 Session 中，并自动断言 `deriveMessages()` 相等。这样该不变式在每次 CI 运行中会被套件产生的所有场景检查数百次，而非仅两次。
+3. **夜间竞态压力测试。** 一个 CI job 以 `vitest --repeat=200`（加 `--shuffle`）运行 agent-loop 和 inbox 套件，以暴露调度依赖的失败；发现的任何不稳定测试都视为 bug 修复，绝不靠重试掩盖。
+
+## 计划
+
+措施 1 和 2 一起落地（它们改动相同的辅助模块）；在套件消除所有睡眠后再添加夜间 job，以确保重复运行速度快。
+
+## 验收标准
+
+- 不再使用 `setTimeout`；lint 规则在 `packages/*/tests` 中强制执行，白名单辅助模块除外。
+- 共享 harness 将每个测试的会话日志回放到全新的 `Session` 中，并自动断言 `deriveMessages()` 相等，覆盖整个套件。
+- 夜间 job 以 `--repeat` 和 `--shuffle` 运行 agent-loop 和 inbox 套件；发现的不稳定测试作为 bug 分诊，绝不靠重试掩盖。
+
+## 风险
+
+Fake timer 与 agent loop 中的 Promise 调度存在微妙交互——优先使用事件驱动等待；仅在测试 timer 服务行为本身时才使用 fake timer。

## Problem
The per-file 100% coverage gate ([the quality-gates decision](../../implemented/process/2026-06-11-quality-gates.md)) proves every line *executes* under test — not that any assertion would notice if the line were wrong. Under agent-written tests, coverage pressure can produce execution-without-assertion. Mutation testing measures what coverage cannot: whether the suite *kills* deliberately injected bugs.

+# Agent Note: 变异测试作为覆盖率的制衡手段
+
+Status: proposed
+
+[English](2026-06-11-mutation-testing.md) | 中文
+
+## 问题
+
+逐文件 100% 覆盖率门禁（[质量门禁决策](../../implemented/process/2026-06-11-quality-gates.md)）证明每一行代码在测试中都被*执行*了，但不能证明如果该行出错，任何断言会注意到。在 agent（智能体）编写测试的场景下，覆盖率压力可能产出「执行但不断言」的测试。变异测试衡量的正是覆盖率无法衡量的：测试套件是否能*杀死*被刻意注入的缺陷。
+
+## 提案
+
+使用 Stryker（`@stryker-mutator/vitest-runner`）对 `packages/*/src` 运行变异测试：
+
+- **PR（Pull Request）范围的增量运行**（仅变更文件），作为一个 CI job。调优后速度足以作为合并门禁。
+- **每夜全量运行**，跟踪变异分数；先记录基线，再将阈值设为观测到的基线并只升不降（与覆盖率策略一致：阈值只收紧）。
+- 存活的变异体是待办项：agent 选取一个存活体、编写杀死它的测试、循环往复——一个形态良好的自主循环。
+- 等价变异体（可证明不改变行为的）加注释排除并附理由，与 `/* v8 ignore */` 策略一致。
+
+## 计划
+
+1. 添加 Stryker 配置，范围限定在一个包（package），即 llm（最小、最具算法性），并测量运行时间。
+2. 扩展到所有包；在配置中记录基线分数。
+3. 接入每夜 job；运行时间可接受后再添加 PR 范围的增量 job。
+
+## 验收标准
+
+- Stryker 配置在 `packages/*/src` 上以 vitest runner 运行；每夜 job 记录变异分数，当分数低于记录的基线时，通过只升不降的阈值使运行失败。
+- PR 范围的增量运行在运行时间可接受后作为合并门禁；或者明确保持仅每夜运行，并将该结论记录于此。
+- 等价变异体带有注释排除及理由，与 `/* v8 ignore */` 策略一致。
+
+## 风险
+
+运行时间：变异测试开销大；逐文件 100% 覆盖率有所帮助（每个变异体至少会被执行到）。如果 PR 范围的运行始终过慢，则保持仅每夜运行，依赖分数只升不降的机制。

Status: rejected — the pervasive `DeepReadonly<T>` type flip is replaced by source-owned runtime immutability in `Session` plus relational development assertions.

## Problem
The rejected proposal targeted an ownership hole that a `readonly SessionEvent[]` type alone cannot close: its elements remain mutable at runtime, so a cast or plain JavaScript can rewrite nested history. The implemented design closes that hole in `Session` by materializing and deep-freezing every accepted event and returning frozen array snapshots. In-flight prompt waterfalls remain intentionally transformable, so immutability is an ownership boundary rather than a blanket type rule.

+# Agent Note: 深度只读的公开接口
+
+Status: rejected — 普遍采用 `DeepReadonly<T>` 的类型翻转已由 `Session` 中归属源的运行时不可变性与关系型开发断言取代。见[归属源的会话不可变性与开发模式不变式](../../implemented/architecture/2026-06-11-dev-invariants-over-deep-readonly.md)。
+
+[English](2026-06-11-immutable-public-surfaces.md) | 中文
+
+## 问题
+
+被否决的提案针对的是一个所有权漏洞：仅靠 `readonly SessionEvent[]` 类型无法封堵该漏洞，因为其元素在运行时仍然可变，类型强制转换或纯 JavaScript 代码可以改写嵌套的历史记录。已实现的设计在 `Session` 中封堵了这一漏洞：对每个被接受的事件进行物化并深度冻结，返回冻结的数组快照。进行中的提示词 waterfall（瀑布式事件）有意保持可变换，因此不可变性是一条所有权边界，而非一条全局类型规则。
+
+## 提案
+
+> **实际采用了不同的实现方式——见 Status 行与[源拥有的会话不可变性与开发模式不变式](../../implemented/architecture/2026-06-11-dev-invariants-over-deep-readonly.md)。** 下文的 `DeepReadonly<T>` 设计已被否决：它仅在编译期生效、对消费方噪音大、且可被强制转换绕过。`Session` 改为在每次组合中对已接受的事件和公开日志快照进行快照与深度冻结；`deriveMessages()` 返回分离的冻结投影；开发插件检查跨记录与跨 seam 的关系。
+
+在类型层面为「突变即损坏」的场景引入不可变性：
+
+- `SessionEvent` 数据在从会话输出时（`events`、`session/event` 监听器）变为 `DeepReadonly`；`append()` 仍接受普通可变输入。一个 `DeepReadonly<T>` 工具类型放在 dsh-llm 中，与 brand/never 辅助类型相邻。
+- `deriveMessages()` 返回深度只读的消息；agent loop（智能体循环）在将可变请求交给 `agent/request` waterfall 之前先克隆（该处的突变是被允许的——克隆使边界显式且代价低廉，每个步骤仅一次）。
+- `PromptAssembly` 在其 waterfall 流经期间保持可变（被允许），但注册表内部的 section 列表在每次组装时被克隆（已有此行为）。
+
+## 计划
+
+引入 `DeepReadonly`，翻转会话的读取路径，并修复消费方中由此产生的编译错误。
+
+## 风险
+
+`DeepReadonly` 类型在 waterfall 边界处（突变本身就是 API 的地方）可能产生噪音较大的错误。应将可变/只读边界精确地划在「已记录 vs 进行中」，并在会话 README 中加以说明。

## Problem
The examples had two shared base files: `examples/base-core.yml` was providerless, while `examples/base.yml` included that core plus the real `llm-deepseek` adapter. Snapshot replay needs the providerless core with `llm-replay`, because loading the real adapter without a key throws. The normal demos need the real adapter. The result was a naming inversion: the file named `base.yml` was not the reusable base for all examples, while the true base was `base-core.yml`.

+# Agent Note: 使共享示例基础配置与提供方无关
+
+Status: rejected — 已由[将示例应用提取到 packages 中](../../implemented/architecture/2026-06-20-extract-example-app-packages.md)取代；后者把主干移入 `dsh-agent-spine-demo` bundle 并删除 `base*.yml` 文件，因此已不存在可重命名的共享基础 YAML。
+
+[English](2026-06-20-providerless-example-base.md) | 中文
+
+## 问题
+
+示例曾有两个共享基础文件：`examples/base-core.yml` 与提供方无关，而 `examples/base.yml` 在该核心基础上加入了真实的 `llm-deepseek` 适配器。快照回放需要与提供方无关的核心配合 `llm-replay` 使用，因为在没有密钥的情况下加载真实适配器会抛出异常。常规演示则需要真实适配器。结果是命名与实际含义倒挂：名为 `base.yml` 的文件并非所有示例可复用的基础，而真正的基础反倒是 `base-core.yml`。
+
+这种拆分可以理解，但它让每次解释配置都变得更冗长。它还导致了别扭的测试搭建方式，例如无密钥冒烟测试不得不携带一个虚拟 API key，仅仅为了让适配器能启动——尽管模型根本不会被调用。
+
+## 提案
+
+将与提供方无关的核心重命名为 `examples/base.yml`，让适配器选择在每个具体示例中显式声明。编码和 ACP（Agent Client Protocol）真实配置添加一小段 `llm-deepseek` include 或本地块；快照配置添加 `llm-replay`。删除 `examples/base-core.yml`。
+
+共享基础应仅包含提供方无关的服务与工具：`llm`、会话、系统提示词、工具、agent（智能体）、不变式、bash 执行器和 bash 工具 schema。任何涉及模型提供方选择的内容都应放在叶子配置中。
+
+## 验收标准
+
+- `examples/base.yml` 与提供方无关。
+- `examples/base-core.yml` 已删除。
+- 真实演示配置显式添加 DeepSeek 适配器。
+- 快照回放配置 include 同一个与提供方无关的基础，并加入其回放适配器。
+- [examples README](../../../../examples/README.md)、各示例 README 及 Agent Note（agent 决策记录）引用不再解释「base = base-core 加适配器」。
+
+## 放弃了什么
+
+真实演示失去了一层便利：每个演示都必须显式引入适配器。对于示例而言这是正确的默认行为，因为适配器选择是可变部分，而与提供方无关的接线才是共享的产品核心。

+# Agent Note: 通过工具调用流式传输工作流进度
+
+Status: rejected — ACP 仅面向自动化；实时工作流展示需要一个面向人类界面的归属方和全新设计。
+
+[English](2026-07-13-stream-workflow-progress-through-tool-calls.md) | 中文
+
+## 问题
+
+工作流引擎有意为 run、phase、narration 和子 agent（智能体）进度发出成对的 `workflow/*` observation 事件，但目前没有生产消费方呈现这些事件。因此，编辑器在最终结果返回之前只显示一张 pending 状态的工作流工具卡片，尽管引擎已经报告了当前活跃的 phase、脚本日志内容以及哪些子 agent 已启动或已结束。[动态工作流决策](../../implemented/feature/2026-07-05-dynamic-workflows.md)明确将 ACP（Agent Client Protocol）进度 UI 保留给这一事件流。
+
+如果让 `dsh-acp` 直接监听工作流事件，就会反转能力边界：通用的 UI 桥接层将依赖一个可选的工作流包（package），并对一个工具名做特殊处理。工具流水线已经拥有实时更新所需的路由信息（agent 和 call id），但只暴露了纯粹的 pending/final 展示器，因此长时间运行的工具没有提供方无关的方式在二者之间报告瞬态 UI 状态。
+
+## 提案
+
+为 `dsh-tools` 添加一条实时进度通道。注册表所有的 `ToolExecution` 新增 `reportProgress(view): boolean`，其中 `view` 是一个独立的、提供方无关的通用进度快照，包含可选的替换标题和面向 UI 的内容块。进度不能更改调用的 args 派生卡片标签、kind、原始输入、locations、terminal intent 或 diff intent；它只更新在最初选定的展示方式内的实时标题/内容。当执行处于活跃状态时，该方法校验并快照 view，然后分发一个受限的、agent 作用域的 `tools/progress` observation，携带权威的执行标识与快照。一旦 final-result 处理开始，方法返回 `false` 且不再分发，因此迟到的异步报告者无法覆盖终态卡片。观察者异常会被记录日志，不会导致工具失败。
+
+`dsh-acp` 以通用方式消费 `tools/progress`。它通过既有的 agent 到会话映射解析执行所属的 agent，并为同一 call id 发出 in-progress 的 `tool_call_update`。由于报告仅在工具执行流水线内可用，持久化的 `tool/call` 及其 ACP `tool_call` 始终先于第一条 update；在 `tools/result` 之前关闭报告者，确保进度更新不会出现在 completed/failed 卡片之后。进度是实时 UI 状态，而非模型输入或持久历史：会话回放继续从 `tool/call` 和 `tool/result` 重建 pending 与 final 卡片，无需重放瞬态更新。
+
+`dsh-tool-workflow` 成为第一个生产者。每次工具执行在调用 `ctx.workflows.start()` 之前安装一个紧凑的事件捕获器，因为合法的引擎可能在 `start()` 内部同步发出进度。在调用返回之前，捕获器将观察到的事件按 `WorkflowRunInfo.id` 归约为候选状态；随后选取返回的 `WorkflowRun.id`，丢弃其他候选，报告累积的快照，并将后续匹配事件直接路由。如果 `start()` 抛出异常，捕获器被 dispose（资源释放），其候选状态被丢弃。这在不向 `WorkflowStartRequest` 添加观察者关联、也不要求进度等到 `start()` 返回的前提下，保持了引擎的可替换性。
+
+归约器消费既有的 start、phase、log、agent-start、agent-end 和 end 事件，报告一个替换快照，包含当前 phase、最新日志行、活跃子 agent 标签以及 completed/failed/cancelled 计数。它不累积 narration transcript（文本记录）；已结束的子 agent 离开活跃集合，变为计数器。`workflow/end`、工具结算或插件 dispose 移除归约器条目和事件捕获器。六种工作流事件及其元数据、成对的子 agent 生命周期、run handle、取消通道和观察者隔离保持不变；第三方观察者可继续直接消费这些事件。
+
+更新工具执行/展示文档、生成的事件与 API 目录、工作流包文档以及工作流数据结构目录。ACP 集成覆盖率必须使用脚本化的模型边界测试真实的工作流工具和 worker seam；主 ACP 快照套件新增一个 workflow-progress 场景，因为这改变了面向编辑器的 transcript。
+
+## 曾考虑的替代方案
+
+**删除工作流 observation 表面。** 在[折叠工作流简化提案](../../rejected/simplification/2026-07-12-collapse-workflow-to-foreground-core.md)中被否决：这些事件及其成对生命周期是有意设计的，缺少的是消费方。
+
+**让 ACP 直接了解工作流。** 这可以将 `WorkflowRunInfo` 映射到会话和卡片，但会使通用桥接层依赖一个可选能力，并绕过「工具拥有展示意图」的规则。工具进度通道为每个长时间运行的工具解决了相同的路由问题。
+
+**将每条进度更新持久化为会话事件。** 这会使实时 narration 可回放，但会用一种状态永久膨胀日志，而该状态的权威持久结果已经是工具调用/结果对。如果可恢复的工作流进度成为产品需求，需要一个工作流日志化设计，而非伪装成持久事实的 UI 快照。
+
+## 验收标准
+
+- `ToolExecution.reportProgress()` 由注册表所有、agent 作用域、快照化、观察者隔离，且在终态处理开始后返回 `false` 而不分发。
+- ACP 将进度路由到正确的实时会话中的正确调用；不同会话中的并发工作流不能串扰，且 `tool_call_update` 不会出现在其 `tool_call` 之前或终态更新之后。
+- 工作流进度显示当前 phase、最新日志行、活跃子 agent 和结果计数，同时保留所有既有 `workflow/*` 事件和 run 语义；一个在 `start()` 内部同步发出 start、phase、log、child 和 end 事件的 seam 测试引擎不会丢失任何归约器状态。
+- 取消、worker 死亡、工具失败、会话关闭和插件 dispose 释放归约器状态；回放仅发出持久的 pending/final 卡片对。
+- 单元测试、工作流集成测试、ACP 集成测试、快照、类型检查、覆盖率、doc-sync（文档同步门禁）、module-graph、构建和 hygiene 门禁全部通过。

+本提案向工具 seam 添加了一个公开的实时进度方法和事件，因此实现方必须精确维护 active/terminal 边界，并在观察者看到快照之前将其分离。pre-start 捕获器可能短暂观察到无关的工作流 run，因此它仅按 run id 持有紧凑的候选状态，并在 `start()` 返回后立即丢弃所有不匹配的候选。一个工作流可能发出大量进度变更；有界归约器避免了 transcript 增长，但在关联完成后仍会为每个有意义的事件发送一条 UI 更新。如果经测量的客户端需要合并更新，这必须是一个带默认值的、经过校验的桥接配置，而非硬编码的节流。瞬态进度在回放时有意消失，因此最终工具结果仍是唯一持久的工作流卡片内容。

## Problem
Per-lifecycle/per-class tables would list facts that are fully derivable: an Agent Note's path encodes lifecycle and class, its filename encodes the first-proposed date, and its H1 carries the title. A hand-maintained copy of those facts would also be a high-contention docs hotspot because concurrent Agent Note branches append rows to the same few lines. [The classification Agent Note](../../implemented/process/2026-06-20-agent-note-classification.md) makes the tree itself authoritative.

+
+Status: rejected — 集中生成的列表容易产生合并冲突，且几乎不增加发现价值
+
+[English](2026-07-04-generate-agent-note-index-tables.md) | 中文
+
+## 问题
+
+按生命周期和分类划分的表格只会列出完全可推导的事实：Agent Note（agent 决策记录）的路径编码其生命周期和分类，文件名编码首次提出日期，H1 承载标题。手工维护这些事实的副本还会成为高冲突文档热点，因为并发的 Agent Note 分支会向相同的几行追加条目。[分类 Agent Note](../../implemented/process/2026-06-20-agent-note-classification.md) 将目录树本身定为权威来源。
+
+## 提案
+
+保留策展文本，并将列表生成为完全生成的 `.agents/notes/INDEX.md`。共享的 `scripts/agent-note-index.ts` 模块将同时负责目录树遍历器和渲染器。两个轻量消费方会共用它：
+
+- `scripts/gen-agent-note-index.ts`（`pnpm run gen-agent-note-index`）将根据目录树完整重写 INDEX.md。
+- `scripts/verify-agent-note-classification.ts` 将检查结构，并断言已提交的 INDEX.md 与新鲜渲染结果逐字节一致。
+
+添加、移动或删除 Agent Note 时，只需编辑 Agent Note 文件并运行生成器。
+
+## 曾考虑的替代方案
+
+### 为什么不在 README.md 中使用标记分隔区域？
+
+README.md 中由标记分隔的表格会混合生成内容与策展文本，因而需要拼接机制并保护周围的契约。专用生成文件至少能将这些关注点分开。
+
+### 为什么不采用纯校验器模式？
+
+它能捕获错误，但每次提案编辑仍然要在手工维护的表格中触碰共享热点。作者已经命名并放置了文件，因此索引副本不增加任何信息。这与[包（package）清单提案](../../proposed/process/2026-06-20-discover-package-inventory.md)对 tsconfig 引用和 knip 配置段所做的手写列表与推导之间的判断相同。
+
+## 后果
+
+- 生成文件将是显式的，且不包含任何策展区域。
+- H1 格式错误或缺失将是硬错误，因为 H1 为每一行提供标题。
+- 即使可以通过重新运行生成器解决冲突，并发分支仍会修改同一个已提交产物。

The canonical session log currently persists every `assistant/chunk` exactly as streamed by the model. The [session persistence Agent Note](../../implemented/architecture/2026-06-14-session-persistence.md) chose this for token-level replay fidelity and contiguous `seq`, but the cost has grown: JSONL fixtures are dominated by tiny delta records, snapshot scenarios replay the model by grouping chunk events, ACP load reconstructs prior assistant output from chunks, and any future log reader must distinguish durable message history from token-level trace.

+# Agent Note: 仅持久化组装后的 assistant 消息，不存储流式分片
+
+Status: rejected — 高保真分片回放、部分失败流与快照回放目前依赖持久化的 `assistant/chunk` 事件。只有具备不丢失信息的回放/产物替代方案后，才能删除分片。
+
+[English](2026-06-20-assembled-assistant-messages-only.md) | 中文
+
+## 问题
+
+当前的规范会话日志会持久化模型流式输出的每一个 `assistant/chunk`。[会话持久化 Agent Note（agent 决策记录）](../../implemented/architecture/2026-06-14-session-persistence.md)选择这一方案是为了 token 级别的回放保真度和连续的 `seq`，但其代价日益增长：JSONL fixture（测试前置数据）被大量微小的 delta 记录占据，快照场景通过对分片事件分组来回放模型，ACP（Agent Client Protocol）加载时从分片重建先前的 assistant 输出，而任何未来的日志读取方都必须区分持久的消息历史与 token 级别的追踪。
+
+对于成功组装出完整内容的步骤，agent loop（智能体循环）已经追加了一条 `assistant/message`。这正是 `deriveMessages()` 用来构造下一次模型请求的事件。换言之，正常的可恢复会话状态无需分片即已具备；分片是实时渲染和确定性测试的产物，不是必需的会话历史。失败或中止的流则不同：部分 assistant 输出可能仅以分片形式存在，而空的 max-token 步骤可能根本不产生 `assistant/message`。
+
+## 提案
+
+停止在规范会话日志中存储 `assistant/chunk`。持久日志保留 `assistant/message`、`tool/call`、`tool/result`、`usage`（如保留）以及轮次边界。实时 UI 仍可通过一个刻意设计为瞬态的流事件接收 token 增量。快照回放应将其模型脚本移入显式的 fixture 伴随文件，或从记录的适配器产物中派生，而非将规范的用户会话当作 token 磁带。需要部分失败流输出的场景必须在回放 fixture 中记录该输出。
+
+ACP `session/load` 可以将先前的 assistant 消息作为完整内容块回放，而非模拟原始的 token 流。加载后的 transcript（文本记录）无需重现每一个历史 delta；它必须展示相同的已完成 assistant 内容，并以有效的提供方历史恢复运行。
+
+## 验收标准
+
+- `SessionEventMap` 移除 `assistant/chunk`，或在需要过渡性实时事件时将其标记为非持久化。
+- [会话持久化文档](../../../../packages/session-persistence/session-persistence/README.md)不再要求逐字存储每个流式分片。
+- `llm-replay` 和 ACP 快照使用显式的回放 fixture 格式或伴随文件来存储模型分片。
+- `session/load` 从 `assistant/message` 渲染已完成的 assistant 消息。
+- 存储的日志大幅缩小，且在没有分片缺口的情况下保持 `seq` 连续。
+- 会话格式版本与已记录的 fixture 一并刷新；按预发布格式策略拒绝非当前版本的存储日志。
+
+## 放弃了什么
+
+规范的用户会话不再能重建旧轮次的精确 token 流。它也会丢失失败或中止流的部分 assistant 输出，除非另有事件或 fixture 记录。对于当前的恢复、加载和快照契约而言，这是过大的信息损失。需要精确确定性流的测试应当直接拥有该 fixture，前提是生产会话日志为用户可见的恢复保留了足够的保真度。

+# Agent Note: 移除 ACP（Agent Client Protocol）session/load，直到恢复具备产品形态
+
+Status: rejected — Zed 是当前目标 ACP 客户端，它声明并实际使用支持加载的会话，还为并发的 `session/load` 保留待加载状态。桥接层应保留 `session/load` 并巩固恢复契约。
+
+[English](2026-06-20-drop-acp-session-load.md) | 中文
+
+## 问题
+
+ACP 声明 `loadSession: true` 并实现 `session/load`：向 bridge 注入持久化能力、校验 cwd 与存储元数据的一致性、从持久化日志重建 agent（智能体），并向客户端回放先前的 transcript（文本记录）更新。该路径有自己的竞态处理、loading-id 守卫、回放展示逻辑和测试。它还依赖规范日志保留足够的 UI 数据，以重建旧的分片和工具展示。
+
+持久化仍然是基础能力，但编辑器可见的恢复尚未经过产品流程设计。目前没有会话选择器、没有标题/预览元数据，也没有明确的加载失败或部分加载的用户体验。bridge 正在为一个仅被测试、文档和当前目标客户端的会话模型所使用的功能付出复杂度代价。
+
+## 提案
+
+当前阶段，ACP 仅启动全新会话。`initialize` 声明 `loadSession: false` 或省略该能力，`session/load` 不予支持。持久化仍可供 agent loop（智能体循环）和测试使用；如果其他消费方需要，恢复仍可作为底层工厂存在。编辑器 bridge 应在具备真正的会话选择 UX 和稳定的 load transcript 契约后，再重新引入 `session/load`。
+
+## 验收标准
+
+- ACP 不再注入 `sessionPersistence`；它原本仅供 `session/load` 使用。
+- `initialize` 不再声明 load 支持。
+- `session/load` handler、loading-id 追踪、已加载会话的 cwd 预检以及 load 回放测试均被移除。
+- 快照 fixture（测试前置数据）不再依赖 load 回放展示。
+- [ACP 文档](../../../../packages/acp/acp/README.md)仅描述全新会话的支持。
+
+## 放弃的能力
+
+编辑器无法通过 ACP 重新打开先前持久化的会话。这确实是一项产品功能，但当前实现超前于 UX 设计，且将 bridge 绑定到 token 级别的日志回放。保留持久化但移除编辑器 load，可将 bridge 收窄到它当前能干净呈现的工作流。

# Agent Note: Drop ACP terminal `_meta` rendering
-Status: rejected — Zed is the current target client, and the terminal `_meta` convention is intentional Zed UX with a plain ACP fallback for other clients.

## Problem
-The ACP bridge implements a Zed-specific terminal-card convention through `_meta.terminal_info`, `_meta.terminal_output`, and `_meta.terminal_exit`. The implemented [rich ACP bash rendering Agent Note](../../implemented/feature/2026-06-18-acp-terminal-and-tool-rendering.md) deliberately avoided ACP's client-side `terminal/create` because bash execution belongs in the harness, but still adopted the reference agents' display-only `_meta` convention. That gives a nicer Zed card at the cost of bridge state, capability negotiation, terminal ids, special update mapping, text fallback tests, and exit-pill parsing in `dsh-tool-bash`.
+The former ACP editor bridge implemented a Zed-specific terminal-card convention through `_meta.terminal_info`, `_meta.terminal_output`, and `_meta.terminal_exit`. The current [render-intent decision](../../implemented/architecture/2026-07-02-tool-render-intent-union.md) preserves the underlying rule that bash execution belongs in the harness and terminal cards are display-only. The later [automation-only ACP decision](../../implemented/simplification/2026-07-23-acp-automation-only-protocol.md) removes the `_meta` projection, bridge state, capability negotiation, terminal ids, special update mapping, text fallback tests, and exit-pill parsing from ACP. TUI and the Web host/client runtime retain the tagged presentation contract, while ACP no longer renders editor cards.
-The fallback path already exists: render the tool call and completed output as normal ACP content blocks. Non-Zed clients rely on that path anyway, but the Zed terminal card is a current target-client feature rather than speculative decoration.

+# Agent Note: 移除 ACP（Agent Client Protocol）终端 `_meta` 渲染
+
+Status: rejected — 在 ACP 仍是编辑器桥接层时，仅移除 Zed 终端元数据的方案被否决；后续仅面向自动化的 ACP 则移除了整个编辑器投影。
+
+[English](2026-06-20-drop-acp-terminal-meta.md) | 中文
+
+## 问题
+
+原 ACP 编辑器桥接层通过 `_meta.terminal_info`、`_meta.terminal_output` 和 `_meta.terminal_exit` 实现了一套 Zed 特有的终端卡片约定。当前的 [render-intent 决策](../../implemented/architecture/2026-07-02-tool-render-intent-union.md)保留了底层规则：bash 执行属于 harness，terminal 卡片只用于展示。后续的[仅面向自动化 ACP 决策](../../implemented/simplification/2026-07-23-acp-automation-only-protocol.md)从 ACP 中移除了 `_meta` 投影、桥接状态、能力协商、终端 id、特殊 update 映射、文本回退测试和 exit-pill 解析。TUI 与 Web 宿主/客户端运行时保留带标签的展示契约，而 ACP 不再渲染编辑器卡片。
+
+本提案提出时，回退路径已经存在：将工具调用和完成输出渲染为普通 ACP 内容块。当时，非 Zed 客户端依赖这条路径，但 Zed 终端卡片是目标客户端的功能特性，而非推测性装饰。
+
+## 提案
+
+忽略 `clientCapabilities._meta.terminal_output`，通过纯 ACP 内容路径渲染 bash 结果。执行仍由 agent 侧的 `dsh-bash` 完成；仅移除展示相关的终端元数据。如果 ACP 日后标准化了 agent 执行的终端，或产品决定 Zed 特有展示值得其维护成本，终端卡片可以再回来。
+
+本提案比[收拢工具自有 UI 展示](2026-06-20-generic-tool-rendering.md)更窄：如果通用的 `presentCall`/`presentResult` 保留，本提案不影响它们，只移除终端子形态与 `_meta` 映射。
+
+## 验收标准
+
+- ACP 不再读取或存储 `_meta.terminal_output` 能力状态。
+- `TerminalRendering`、终端 id、终端 cwd 解析与 `_meta.terminal_*` update 映射从 `@deepseek-ai/dsh-acp` 中消失。
+- `ToolTerminal` 从 `@deepseek-ai/dsh-tools` 中消失，或在展示清理中因未使用而删除。
+- Bash 结果展示不再为终端 pill 解析退出状态。
+- [仅面向自动化 ACP 决策](../../implemented/simplification/2026-07-23-acp-automation-only-protocol.md)后来移除了 ACP 终端卡片，并吸收了其中有关执行归属的决策依据。
+
+## 放弃的内容
+
+如果采用本提案，Zed 用户会失去专用终端卡片：没有 cwd 头部、终端展示或 exit pill。但他们仍会以纯内容形式看到命令和输出。当时 ACP 桥接层尚未发布，且 `_meta` 键只是约定而非标准；在这种情况下，考虑这项简化是合理的。

Status: rejected — full-output recovery is a real bash behavior. A future artifact/blob service may generalize it, but dropping spill files before that replacement would lose useful command output.
+English | [中文](2026-06-20-drop-bash-output-spill-files.zh.md)

## Problem
`dsh-bash-local` keeps bounded in-memory output and spills large stdout/stderr streams into private temp files. That requires a private directory, random owner-only file creation, close-failure handling, byte-offset incremental reads, lossy read reporting, path rendering in model-facing text, and cleanup discipline. The tool then tells the model to read a local spill path when output was truncated.

+# Agent Note: 移除 bash 完整输出溢出文件
+
+Status: rejected — 完整输出恢复是真实的 bash 行为。未来的产物/blob 服务或许能将其泛化，但在替代方案就位前删除溢出文件会丢失有用的命令输出。
+
+[English](2026-06-20-drop-bash-output-spill-files.md) | 中文
+
+## 问题
+
+`dsh-bash-local` 在内存中保留有界的输出，并将大体量的 stdout/stderr 流溢出到私有临时文件。这要求一个私有目录、仅所有者可写的随机文件创建、关闭失败处理、基于字节偏移的增量读取、有损读取报告、在面向模型的文本中渲染路径，以及清理纪律。当输出被截断时，该工具会告知模型去读取一个本地溢出路径。
+
+这解决了一个真实问题，但方式狭隘且有泄漏。溢出路径是一个暴露在模型输出中的进程级文件系统产物，而非具有作用域访问控制、保留策略或 UI 支持的持久化 harness 产物。它还使后台任务的读取变得复杂，因为有损增量读取必须指向一个或两个溢出文件。
+
+## 提案
+
+保留尾部截断，移除完整输出溢出文件。bash 结果包含有界的尾部内容加一个明确的截断标记；不输出路径。如果用户需要恢复完整输出，则添加一个通用的产物/blob 服务（具有明确的所有权、清理和 UI 渲染），然后让 bash 将大体量输出附加到该服务。
+
+本提案可以独立于[通用长时间运行工具运行时](../../implemented/architecture/2026-06-20-generic-long-running-tool-runtime.md)落地。如果后台任务保留，`bash_output` 仍应报告输出已被丢弃，但不再提供溢出路径。
+
+## 验收标准
+
+- `CollectedOutput` 不再携带溢出路径。
+- `OutputCollector` 仅保留有界缓冲区，删除临时文件机制。
+- `renderResult()` 报告截断时不包含文件系统路径。
+- 测试覆盖尾部截断，不再断言完整输出文件的内容。
+- [docs/defensive-patterns.md](../../../../docs/defensive-patterns.md) 中的安全指导不再将私有溢出文件视为面向模型的接口。
+
+## 放弃的能力
+
+模型或用户无法再从临时文件恢复大体量命令输出中被省略的前缀。在真正的产物服务出现之前，这是可以接受的。当前的溢出路径为一个生命周期和权限均未经设计的功能引入了过多的定制机制。

## Problem
The session log stores `step/start` and `step/end` events even though every step-scoped event already carries `{ turn, step }`: assistant chunks, assistant messages, tool calls, tool results, usage, and errors. `deriveMessages()` ignores step boundaries, ACP ignores them for UI, and the main consumers are invariants, tests, snapshot expected outputs, and crash repair.

+# Agent Note: 移除持久化的步骤边界事件
+
+Status: rejected — `step/end` 是模型步骤已完成的持久信号；保留对称的 `step/start` / `step/end` 对，比从相邻的步骤作用域事件推断完成状态更便于理解崩溃修复、不变式与 transcript（文本记录）检查。
+
+[English](2026-06-20-drop-durable-step-boundaries.md) | 中文
+
+## 问题
+
+会话日志存储了 `step/start` 和 `step/end` 事件，尽管每个步骤作用域的事件本身已经携带 `{ turn, step }`：assistant 分片、assistant 消息、工具调用、工具结果、用量和错误。`deriveMessages()` 忽略步骤边界，ACP（Agent Client Protocol）在 UI 层面也忽略它们，主要消费方是不变式检查、测试、快照预期输出和崩溃恢复。
+
+被否决的论点是：边界事件使日志更像仪式而非信息。实际上，`step/end` 是具体信息：读者无需从下一个事件推导状态，就能判断一次模型请求是已完成、已崩溃还是正在修复。同样，一个孤立的 `step/start` 对于「模型请求已发起但在产生任何分片之前就失败了」的场景也有价值。
+
+## 提案
+
+将轮次作为唯一的持久化边界。`step/start` 和 `step/end` 将从 `SessionEventMap` 中移除；在需要分组的事件上保留数值型 `step` 字段。agent loop（智能体循环）递增步骤计数器并以该编号记录步骤作用域的事件，但不再追加开/关边界事件。消费方通过共享 `(turn, step)` 的连续事件推断步骤分组。
+
+不变式插件应当强制步骤作用域的事件在一个已打开的轮次内具有有效的正整数步骤编号，而非要求独立的边界记录包围它们。崩溃恢复不应合成 `step/end`；如果一个被中断的轮次被保留，修复路径仍然可以关闭该轮次而无需捏造步骤边界记录。
+
+## 验收标准
+
+- `SessionEventMap` 不再包含 `step/start` 或 `step/end`。
+- agent loop 中不再有 `closeStep()` 终结路径。
+- ACP 快照和持久化契约 fixture（测试前置数据）不再期望步骤边界行。
+- `deriveMessages()` 和回放从步骤作用域的事件推导出相同的消息历史。
+- [事件分类体系文档](../../../../docs/architecture.md)将轮次描述为持久化边界，将步骤描述为步骤作用域记录上的一个字段。
+- 会话格式版本和已记录的 fixture 被刷新；按预发布格式策略，非当前版本的已存储日志被拒绝。
+
+## 放弃了什么
+
+日志不再将「一次模型请求已发起但进程死亡前未产生任何事件」记录为持久化事实，也不再有显式的「此步骤已完成」标记。在会话日志仍是持久化回放与审计表面的当下，这一损失不可接受。

+# Agent Note: 移除未使用的会话血缘元数据
+
+Status: rejected — `parentSession` 是已记录的 fork/subagent seam 的一部分，并已由 agent（智能体）/会话恢复路径保留。该字段面向未来，但并非意外遗留的死状态。
+
+[English](2026-06-20-drop-unused-session-lineage.md) | 中文
+
+## 问题
+
+`SessionHeader.parentSession` 记录新会话从哪个会话 fork 而来。它在 `dsh-session` 中定义，被持久化后端保留，在恢复流程中复制，作为血缘元数据被文档记录，并有往返测试覆盖。然而仓库中没有任何生产环境的 fork UI 或 subagent 流程读取它。计划中的 subagent/fork seam 仍是 TODO，因此该字段目前只是预存的未来形状。
+
+单个文件的成本虽小，但在格式层面影响面广：每个后端 schema 和元数据序列化器都在保留一个尚无已完成功能读取的值。由于 header 是磁盘契约，即使是占位字段也会成为未来重构必须维护、迁移或有意打破的东西。
+
+## 提案
+
+移除 `parentSession`，使其不再属于 `SessionHeader`，直到真正的 fork/恢复功能需要血缘信息时再引入。如果存在相应 API，fork 仍然可以用先前事件来初始化新会话，但持久化的父指针应当与读取它的功能和解释它的 UX 一同引入。
+
+如果血缘信息回归，届时再决定它应放在不可变 header 中、会话图索引中，还是作为一等事件。当前字段不应预先锁定那个设计。
+
+## 验收标准
+
+- `SessionHeader` 仅包含 version、id、createdAt 和可选的 cwd。
+- JSONL 与 SQLite 元数据 schema 不再存储父会话 id。
+- 恢复与列表 API 不再往返传递 `parentSession`。
+- 文档和测试移除没有生产消费方支撑的 fork 血缘声明。
+- 会话格式版本、后端 schema 版本与记录的 fixture（测试前置数据）按需刷新；按预发布格式策略，非当前版本的存储数据将被拒绝，不提供迁移路径。
+
+## 放弃了什么
+
+代码库失去了一个为未来 fork/subagent UX 预备的现成血缘钩子。这是有意为之。该字段在功能存在时很容易重新引入，而未发布的立场允许格式变更无需迁移。

`dsh-session-persistence` is an interface package whose main concepts are already owned by `dsh-session`: `SessionHeader`, `SessionEvent`, `SessionId`, `session/event`, and `session/flush`. The package adds the abstract `SessionPersistence` service, the shared write coordinator, and contract helpers. Backend packages depend on it, and `agent-loop` has to optionally find a sibling service for resume.

+# Agent Note: 将持久化接口合并进 dsh-session
+
+Status: rejected — 独立的持久化接口包是为持久后端设计的模块化能力 seam。将其折叠进 `dsh-session` 虽能减少包数量，却会牺牲更清晰的后端边界。
+
+[English](2026-06-20-fold-session-persistence-interface.md) | 中文
+
+## 问题
+
+`dsh-session-persistence` 是一个接口包（package），其核心概念已经由 `dsh-session` 拥有：`SessionHeader`、`SessionEvent`、`SessionId`、`session/event` 与 `session/flush`。该包额外添加了抽象的 `SessionPersistence` 服务、共享写入协调器和契约辅助工具。后端包依赖它，`agent-loop`（智能体循环）也需要可选地查找一个同级服务来实现恢复。
+
+当持久化还是一个全新的可替换后端设计时，能力 seam 的拆分是合理的。但在可变摘要被移除之后，这个接口包基本上只是包装了会话日志自身的存储关切。继续保持独立可能带来的仪式感多于清晰度。
+
+## 提案
+
+将抽象的 `SessionPersistence` 服务、协调器和持久化契约辅助工具移入 `dsh-session`。JSONL 和 SQLite 仍作为独立的后端包，注册由会话包拥有的服务。这样既保留了后端可替换性，又删除了一个支撑包和一条跨包 seam。
+
+实施 PR（Pull Request）应更新[能力 seam](../../implemented/architecture/2026-06-13-capability-seams.md) 指南，补充此例外：持久化不同于 bash 或 LLM（大语言模型），因为它的词汇和生命周期事件本就属于会话包的核心领域。
+
+## 验收标准
+
+- `@deepseek-ai/dsh-session-persistence` 作为包被移除。
+- `dsh-session` 导出持久化服务类型、协调器和契约辅助工具。
+- JSONL 和 SQLite 后端包直接依赖 `dsh-session`。
+- `agent-loop` 的恢复功能使用会话包拥有的服务键。
+- [会话持久化](../../implemented/architecture/2026-06-14-session-persistence.md)、[共享持久化写入协调器](../../implemented/architecture/2026-06-18-shared-persistence-write-coordinator.md)与[包文档](../../../../packages/session-persistence/session-persistence/README.md)说明后端实现为何仍保持独立。
+
+## 放弃了什么
+
+`dsh-session` 变得更重：它同时拥有内存日志和持久化接口。这就是代价。如果第三方持久化后端已经形成公开生态，独立的接口包会是更清晰的 SDK 边界；但在预发布阶段，在尚无外部消费方时，多出的包看起来更像是过早的抽象。

# Agent Note: Collapse tool-owned UI presentation
-Status: rejected — tool-owned presentation should wait for more real tools before being generalized or deleted. Bash and ACP currently need the existing richer presentation path.
+Status: rejected — TUI and the Web host/client runtime consume the tagged render-intent union, so tool-owned presentation remains current even though ACP no longer projects it.

## Problem
-Tools can define `presentCall()` and `presentResult()` callbacks that return `ToolCallPresentation`, `ToolResultPresentation`, and optional `ToolTerminal` fields. The code itself flags the design as muddy: title, kind, raw input, content, terminal cwd, terminal output, exit code, and signal grew incrementally into a bag of optional fields. ACP then maintains pending call state to pair a result with the original args, creates replay-only presenters on `session/load`, and maps terminal subfields into Zed-specific `_meta`. `dsh-tool-bash` even parses exit status back out of rendered text because the pure replay-safe presenter no longer has the structured `BashRunResult`.
+The optional-field bag and ACP editor mapping below were the proposal-time context for this rejection. The current contracts live in [the tagged render-intent union](../../implemented/architecture/2026-07-02-tool-render-intent-union.md) and [automation-only ACP](../../implemented/simplification/2026-07-23-acp-automation-only-protocol.md).

+当时，工具可以定义 `presentCall()` 和 `presentResult()` 回调，返回 `ToolCallPresentation`、`ToolResultPresentation` 以及可选的 `ToolTerminal` 字段。代码本身就标记了这个设计的混乱：title、kind、raw input、content、terminal cwd、terminal output、exit code 和 signal 已经逐步增长为一堆可选字段。ACP 随后维护 pending call 状态以将 result 与原始 args 配对，在 `session/load` 时创建仅用于回放的 presenter，并将 terminal 子字段映射为 Zed 特有的 `_meta`。`dsh-tool-bash` 甚至从渲染后的文本中反向解析退出状态，因为纯回放安全的 presenter 已经拿不到结构化的 `BashRunResult`。
+
+当时，真正的第一方用途是为 ACP 提供 bash 展示。这点证据不足以作为冻结一个跨包（package）UI 展示 API 的依据。
+
+## 提案
+
+暂时移除工具自有的 UI 展示回调。规范的工具事件已经携带工具名、原始参数字符串、结果内容和错误状态。UI 从这些字段渲染一个通用的工具卡片。工具特有的富展示可以在至少有两个真实工具和两个真实消费方来验证词汇之后，以带标签的 render-intent union 形式回归。
+
+## 曾考虑的替代方案
+
+作为更小的替代方案，可以在一个 PR（Pull Request）中将当前的可选字段集合替换为一个显式 union；但如果目标是简化，更彻底的做法是删除回调、保留通用路径。
+
+## 验收标准
+
+- `ToolDefinition` 移除 `presentCall` 和 `presentResult`。
+- `ToolCallPresentation`、`ToolResultPresentation`、`ToolTerminal` 和 `ToolCallKind` 消失，除非一个最小的通用 UI 类型仍需要其中之一。
+- ACP 不再维护 presenter pending 状态，也不再在实时流式输出/加载回放期间调用工具回调。
+- `dsh-tool-bash` 不再解析渲染文本来恢复退出状态以供 UI pill 使用。
+- 快照预期输出展示通用工具卡片和文本结果。
+
+## 放弃了什么
+
+如果采用本提案，Bash 会失去其自定义的终端风格卡片和模型生成描述的放置位置。届时，回退方案仍然合理：命令会作为工具输入展示，输出会作为文本展示。只有当产品拥有足够的 UI/工具多样性、足以支撑一份稳定的展示契约时，才会设计富展示。
+
+## 相关
+
+后续的[带标签 render-intent 联合类型](../../implemented/architecture/2026-07-02-tool-render-intent-union.md)在多类生产者与消费方为这套词汇提供充分依据后，实现了较小的替代方案。[ACP 作为仅面向自动化的协议](../../implemented/simplification/2026-07-23-acp-automation-only-protocol.md)移除了 ACP 的编辑器投影，但没有从 TUI 或 Web 宿主/客户端运行时中移除工具自有的展示。

Status: rejected — mid-turn steering is an intentional agent capability for between-step user/plugin input and future goal/loop workflows. It is complexity with a product direction, not an accidental duplicate of `send()`.
+English | [中文](2026-06-20-retire-mid-turn-steering.zh.md)

## Problem
The agent exposes two user-message paths that look close but have different lifecycle semantics: `send()` queues a normal user turn, while `steer()` injects a message between steps of the currently running turn and falls back to `send()` when idle. That distinction leaks through the whole stack: `Agent.steer()` is public API, the session log has a durable `steering/message` event, the agent event taxonomy has `agent/steering`, the loop maintains a steering FIFO beside the queued-message FIFO, cancellation clears both queues, and `deriveMessages()` has to render steering as a tagged synthetic user message rather than a normal prompt.

+# Agent Note: 移除轮次中途引导
+
+Status: rejected — 轮次中途 steering（中途引导）是一项有意设计的 agent（智能体）能力，用于接收步骤之间的用户/插件输入以及未来的 goal/loop 工作流。它是面向产品方向的复杂度，而非 `send()` 的意外重复。
+
+[English](2026-06-20-retire-mid-turn-steering.md) | 中文
+
+## 问题
+
+agent 暴露了两条用户消息路径，外观相近但生命周期语义不同：`send()` 将一条普通用户轮次排入队列，而 `steer()` 在当前运行轮次的步骤之间注入一条消息，空闲时则回退为 `send()`。这一区分贯穿整个栈：`Agent.steer()` 是公开 API；会话日志有持久化的 `steering/message` 事件；agent 事件分类体系有 `agent/steering`；agent loop（智能体循环）在排队消息 FIFO 之外还维护一个 steering FIFO；取消操作需要清空两个队列；`deriveMessages()` 必须将 steering 渲染为带标签的合成用户消息，而非普通提示词。
+
+续行 seam 进一步放大了成本。`agent/turn-continuation` 默认条件为 `hadToolCalls || steeringInjected`，因此同一轮次内的 steering 消息即使模型未请求工具调用，也会强制循环再次调用模型。注释中提到了未来 `/goal`、`/loop` 和预算守卫的用途，但当前仓库没有生产级监听器；只有测试注册了该 waterfall（瀑布式事件）。另外，唯一调用 `steer()` 的生产 UI 是 stdio 演示。ACP（Agent Client Protocol）在轮次运行期间已经通过普通队列发送提示词。
+
+## 提案
+
+暂时删除轮次中途的用户 steering。`Agent.send()` 成为提交用户内容的唯一公开方式；当 agent 正在运行时，内容等待下一个轮次。循环仅因工具调用而在轮次内继续，不因用户在某个步骤运行期间输入内容而继续。调用方若要中断当前轮次，使用 `cancel()` 后再 `send()`。
+
+移除 `Agent.steer()`、steering FIFO、`steering/message`、`agent/steering`、由 steering 驱动的续行逻辑，以及取消操作中区分排队消息与 steering 消息的逻辑。除非实现 PR（Pull Request）发现了生产级监听器，否则在同一变更中一并移除 `agent/turn-continuation`；没有 steering 后，当前仓库不再有具体的续行消费方。如果将来真正的预算或目标插件需要强制续行，应以该插件为具体消费方重新引入一个更窄的 seam。
+
+## 验收标准
+
+- `Agent` 暴露唯一的用户消息入口 `send()`。
+- 持久化会话事件词汇不再包含 `steering/message`。
+- `deriveMessages()` 渲染普通用户消息和上下文注入，不存在 steering 标签路径。
+- 循环只有一个排队消息 FIFO，没有同轮次用户消息续行路径。
+- `agent/turn-continuation` 被移除，或收窄到有具名的生产级消费方。
+- stdio UI 和文档将运行期间的输入描述为「排入下一轮次的输入」。
+- 会话格式版本和已录制的 fixture（测试前置数据）已刷新；非当前版本的存储日志按预发布格式策略被拒绝。
+
+## 放弃了什么
+
+用户无法在模型处于工具步骤之间时添加同轮次 steering 内容。这种行为在理论上对「你已经在工作了，也考虑一下 X」的场景有用，但它不是 ACP 当前暴露的行为，且使轮次边界更难推理。更简单的行为是合理的：用户输入成为下一条提示词，取消操作仍是替换进行中工作的显式手段。
+
+## 相关
+
+本提案与[移除持久化步骤边界](2026-06-20-drop-durable-step-boundaries.md)天然配对，因为移除同轮次 steering 和 `agent/turn-continuation` 后，工具调用成为一个轮次包含多个模型步骤的唯一原因。

## Problem
The ACP bridge now supports multiple live sessions on one JSON-RPC connection. That capability brings multi-entry session maps, reverse session/agent lookups, per-session prompt state, loading ids, demux for every event, cross-session teardown, and isolation concerns for future permission prompts and background tasks. The older [multi-session ACP proposal](../../implemented/feature/2026-06-14-acp-multi-session.md) still tracks the unfinished permission-ownership piece; this Agent Note is the competing simplification path.

+# Agent Note: 将 ACP（Agent Client Protocol）桥接恢复为每连接一个活跃会话
+
+Status: rejected — Zed 是当前目标 ACP 客户端，其 ACP 实现明确支持多会话：它把活跃会话存入 `HashMap<SessionId, AcpSession>`，跟踪 `pending_sessions`，合并同一 id 的并发加载，并测试加载期间关闭的行为。
+
+[English](2026-06-20-single-session-acp-bridge.md) | 中文
+
+## 问题
+
+ACP 桥接现在支持在一条 JSON-RPC 连接上承载多个活跃会话。这一能力带来了多条目会话映射、反向会话/agent（智能体）查找、逐会话的提示词状态、加载中 id、每条事件的解复用、跨会话拆除，以及未来权限提示与后台任务的隔离问题。较早的[多会话 ACP 提案](../../implemented/feature/2026-06-14-acp-multi-session.md)仍在追踪未完成的权限归属部分；本 Agent Note（agent 决策记录）是与之竞争的简化路径。
+
+产品目标已经证明它需要在一个 harness 进程上承载并发的编辑器对话：Zed 的 ACP 连接拥有多个会话和加载状态。快照回放层仍然避免并发模型流，因为其回放条目是位置相关的；这是测试 fixture（测试前置数据）的局限，而非移除桥接多路复用的理由。
+
+## 提案
+
+将 ACP 的范围收回到每连接一个活跃会话。`session/new` 或 `session/load` 创建唯一的会话记录；在现有会话被 dispose（资源释放）或连接关闭之前，第二个活跃会话请求将被拒绝。如果编辑器需要多个聊天标签页，可以启动多个 agent 子进程，直到桥接具备具体的多会话 UX 和权限模型。
+
+移除多会话映射和解复用逻辑，改用单一的 `SessionRecord | undefined` 即可。桥接仍可保留使 dispose 正确的 agent/会话生命周期 seam；简化仅针对在同一传输层上多路复用多个活跃会话这一点。
+
+## 验收标准
+
+- ACP 每连接只有一条活跃会话记录。
+- 当该记录存在时，`session/new` 和 `session/load` 拒绝请求。
+- 事件处理器不再在 `Map<sessionId, record>` 上做解复用。
+- 多会话测试被移除，或移至继续支持多路复用的提案下。
+- 既有的[多会话 ACP 提案](../../implemented/feature/2026-06-14-acp-multi-session.md)更新为链接本 Agent Note，并继续作为当前方向。
+
+## 放弃了什么
+
+ACP 客户端无法在一个服务器进程上承载多个并发对话。这是一项有实质意义的能力削减。对于一个尚未发布的 harness 而言，更简单的模型仍然合理：一个编辑器对话对应一个 agent 进程，跨会话的权限/后台任务隔离不再是活跃的正确性负担。

## Problem
The current persistence contract preserves a final turn that was durably written but never closed. On load, `interruptedTurnClosers()` scans the tail, synthesizes error `tool/result` events for unanswered tool calls, appends a `step/end` when a step is open, appends `turn/end { kind: 'interrupted' }`, and asks the backend to durably commit that repair. The coordinator, JSONL backend, SQLite backend, session event vocabulary, invariants, docs, and tests all model this synthetic close path.

+# Agent Note: 加载时截断被中断的最终轮次
+
+Status: rejected — 单个轮次可以包含大量真实工作，包括多个步骤和大量工具输出。保留被中断的轮次，优于在加载时静默丢弃这段尾部。
+
+[English](2026-06-20-truncate-interrupted-turns.md) | 中文
+
+## 问题
+
+当前的持久化契约会保留已持久写入但从未关闭的最终轮次。加载时，`interruptedTurnClosers()` 扫描尾部，为未应答的工具调用合成 error `tool/result` 事件，在步骤处于打开状态时追加 `step/end`，追加 `turn/end { kind: 'interrupted' }`，并要求后端持久提交这次修复。协调器、JSONL 后端、SQLite 后端、会话事件词汇、不变式、文档和测试都对这条合成关闭路径进行了建模。
+
+这是一套庞大的机制，只为保留上次崩溃轮次中的部分工作。它还会凭空创造从未发生过的事件。合成的工具结果虽然有用（因为它使提供方历史保持合法），但也意味着恢复后的日志中包含了模型可见、却并非任何工具产出的文本。当前设计在尚无已发布产品、也没有真实恢复 UX 来证明部分轮次恢复确有价值的情况下，就优化了最大化尾部保留。
+
+## 提案
+
+加载时只保留最后一个已完成的轮次。后端仍然容忍并截断撕裂的最终记录，但如果解析出的持久前缀止于一个打开的 `turn/start` 之后，规范的修复方式是丢弃上一个 `turn/end` 之后的所有事件。不合成 `tool/result`，不合成 `step/end`，不追加 `turn/end { interrupted }`，也不引入 `interrupted` 轮次结束原因。
+
+这使持久化的轮次边界变得简单：一个已完成的 `turn/end` 就是检查点。最后一个检查点之后的内容都是崩溃尾部。下一次提示词从最后一个已知合法的提供方 transcript（文本记录）恢复，而不是从部分重建的最终轮次恢复。
+
+## 验收标准
+
+- `TurnEndReasonMap` 移除 `interrupted` 变体。
+- `interruptedTurnClosers()` 及其测试删除。
+- 持久化协调器的修复钩子截断后端特有的撕裂/打开尾部状态，不追加关闭事件。
+- [会话持久化文档](../../../../packages/session-persistence/session-persistence/README.md)说明加载返回最后一个已完成的轮次，不包含部分最终轮次。
+- 快照与契约测试随其所固定的行为一同更新。
+- 会话格式版本与记录的 fixture（测试前置数据）刷新；按预发布格式策略，非当前版本的存储日志被拒绝，不提供迁移路径。
+
+## 放弃的内容
+
+崩溃可能丢失最终轮次中的真实工作：上一个 `turn/end` 之后追加的助手文本、工具调用和工具输出。这是有意为之的简化。产品尚未发布，最终轮次恢复的语义未经用户验证，而一个干净的「已完成轮次即检查点」模型在解释、测试和实现上都容易得多。未来若需「恢复部分崩溃工作」功能，应设计为面向用户的显式恢复视图，而非静默插入规范 transcript 的合成事件。
+
+## 相关
+
+本提案是对[会话持久化](../../implemented/architecture/2026-06-14-session-persistence.md)与[轮次封闭不变式](../../implemented/architecture/2026-06-15-turn-enclosure-invariant.md)的直接简化。它还移除了持久化步骤边界事件的大部分动机，使[移除持久化步骤边界事件](2026-06-20-drop-durable-step-boundaries.md)的改动更小。

+## 问题
+
+[subagent seam](../../implemented/feature/2026-06-21-subagent-capability-seam.md) 交付了一套两层能力设计：启动时由服务检查的能力 flag，以及 `SubagentRun` 上的可选运行时方法。三个启动时功能和两个可选运行时方法的实现数与调用数均为零：
+
+- **`outputSchema`/`structured` 与 `toolFilter`**（`SubagentCapabilities`、`SubagentStartRequest`、`SubagentResult`，位于 `packages/subagent/subagent/src/types.ts`）：在作出决策时，每个真实提供方都声明 `outputSchema: false, toolFilter: false`（`packages/subagent/subagent-spawn/src/index.ts`、`packages/subagent/subagent-fork/src/index.ts`、`packages/subagent/subagent-acp/src/index.ts`）；唯一的生产环境 `ctx.subagents.start` 调用方（`packages/subagent/tool-subagent/src/index.ts`）构造 `{ prompt, parent, signal?, agentOptions? }`，结构上无法设置这两个字段；`structured` 仅出现在脚本化测试 fixture（测试前置数据）中。服务的能力检查包含两行 assert，其唯一执行者是拒绝测试。
+- **`SubagentRun.sendMessage` / `SubagentRun.resume`**（同一文件）：没有任何提供方实现——包括 mock 也没有；spawn spec 断言的正是它们的*缺失*。
+
+在作出决策时，`dsh-subagent` 依赖 `dsh-tools` 的唯一原因是 `outputSchema` 的 schema 类型（现为 `ObjectJsonSchema`）。三个后续 subagent 工作流（按会话快照回放、fork seed 边界、ACP（Agent Client Protocol）后端）都围绕这块接口面落地，却没有增长出哪怕一个消费方。
+
+## 提案
+
+从 seam 中移除 `outputSchema`/`structured`、`toolFilter`、`sendMessage` 与 `resume`；将 `SubagentCapabilities` 缩减为 `{ depthLimit }`；删除两行能力 assert、三个提供方上的 all-false flag、脚本化 fixture 的 structured 分支和能力旋钮，以及为固定被移除接口面而存在的测试。`dsh-tools` 的 peer/dev 依赖应从 `packages/subagent/subagent/package.json` 中删除。更新 [subagent.md](../../../../docs/core-data-structures/subagent.md) 中的粘贴内容与 type-equiv manifest（元数据清单），以及受影响的提供方 README。实现 PR（Pull Request）按照 [implemented/AGENTS.md](../../implemented/AGENTS.md) 修订 seam Agent Note（agent 决策记录）的能力目录。
+

+这是[从持久化 seam 裁剪死方法](../../implemented/simplification/2026-06-20-prune-dead-seam-methods.md)在 seam 词汇层面的回响：每个实现都必须为无人声明的成员，甚至更弱，因为这里连一个实现都没有。
+
+## 曾考虑的替代方案
+
+### 为什么不保留？
+
+两类能力的设计是 seam Agent Note 的核心亮点，日后重新添加 `outputSchema` 会涉及多个文件。但该设计以 `depthLimit` 作为活跃示例、以 Agent Note 作为记录仍然成立；而且 seam Agent Note 本身承认已交付的 `toolFilter` 形态是错误的（真正的强制需要在子 agent 上下文中实施 `tools/pre-execute` deny，而非 schema 过滤）——该 deny 原语已存在于拦截 seam 上，因此基于真实实现提供方重新添加时，将固定出一份比当前推测性契约更好的契约。
+
+## 验收标准
+
+- 被移除的拼写仅出现在本 Agent Note 和修订后的 seam Agent Note 中；`SubagentCapabilities` 为 `{ depthLimit: boolean }`；`dsh-tools` 依赖边已消除（`hygiene` 绿色）。
+- 深度强制测试不变且绿色。

+## 风险

+English | [中文](2026-07-12-collapse-workflow-to-foreground-core.zh.md)

## Problem
The workflow capability executes foreground JavaScript that composes subagents, but it also carries an unconsumed progress-observation system. No production listener subscribes to any of the six `workflow/*` events; listeners exist only in workflow tests. Nevertheless the seam defines run/phase/agent outcome payloads, the worker sends phase/log/agent lifecycle protocol messages, the host forwards them through a `liveAgents` pairing ledger, and the engine maintains run ids solely to correlate those notifications.

+# Agent Note: 将工作流收缩至已使用的前台核心
+
+Status: rejected — 工作流进度是有意设计的观测接口面；应通过消费方使其发挥作用，而非删除它。
+
+[English](2026-07-12-collapse-workflow-to-foreground-core.md) | 中文
+
+## 问题
+
+工作流能力执行前台 JavaScript 来编排 subagent，但它同时携带了一套无人消费的进度观测系统。没有任何生产环境的监听器订阅六个 `workflow/*` 事件中的任何一个；监听器仅存在于工作流测试中。尽管如此，seam 定义了 run/phase/agent（智能体） outcome 载荷，worker 发送 phase/log/agent 生命周期协议消息，host 通过一个 `liveAgents` 配对账本转发它们，引擎维护 run id 仅仅是为了关联这些通知。
+
+这套进度词汇不仅仅是未被使用；它在不经重新设计的情况下也无法服务于其唯一已命名的未来消费方。`WorkflowRunInfo` 包含 `{id, meta}` 但没有父 agent、会话或工具调用标识，而面向模型的工具也从不暴露 run id。一个全局 ACP（Agent Client Protocol）监听器无法将事件路由到正确的客户端会话。`meta.phases` 从未被查询，`phase(title)` 不对其做校验，phase 的 `detail`/`model` 和 agent 的 `label`/`phase` 仅供事件消费，`whenToUse` 被校验和复制但从未被渲染或用于选择。`phase()` 和 `log()` 仍然跨越 worker 边界，尽管没有接收方。
+
+live handle 在观测者消失后仍重复事件时代的数据。`WorkflowRun.id` 没有非事件消费方，而工具读取 `run.meta.name` 只是为了渲染一个它已经以 `args.meta.name` 形式持有的值；两者都不属于执行/取消 handle。
+
+取消机制也为一个同步启动提供了两条公开通道。`WorkflowStartRequest.signal` 被传递给 worker host，而唯一的生产调用方另外将同一个 signal 桥接到 `WorkflowRun.cancel()`。因为 `start()` 在控制权让出之前就返回了 run，不存在需要请求时取消的就绪窗口；重复的 signal 增加了 host 的 listener/disarm 状态却没有封堵任何竞态。
+
+`WorkflowError.fatal` 是同一种推测性分支的微缩版：所有生产环境的构造都是 fatal 的，`fatal: false` 仅存在于测试中，组合子已经通过 `instanceof` 区分工作流失败。
+
+## 提案
+
+保留已使用的核心：`agent(prompt, { schema, model })`、`parallel`、`pipeline`、`args`、并发/agent 上限、取消、有界 dispose（资源释放）、结构化结果、worker 隔离与前台工具收集。移除所有 `workflow/*` 事件及其仅供事件使用的 info/outcome 类型；移除 `phase()`、`log()`、agent 的 `label`/`phase`、phase 声明、`whenToUse` 及其 worker 消息/host 观测者；将工作流元数据收缩为工具实际使用的 name；移除仅供事件使用的 run id/meta 快照与合成的 agent-end 账本。将 `WorkflowRun` 收缩为 `result`、`cancel()` 和 `dispose()`；工具渲染请求方持有的 name。移除 `WorkflowStartRequest.signal` 及 worker host 的 input-signal listener/disarm 状态，保留调用方从其 abort signal 到 `run.cancel()` 的桥接。将 `WorkflowError` 变为单一的 fatal 错误类，不再有布尔模式或 `isFatalWorkflowError()` 辅助函数。
+
+修订已实施的动态工作流 Agent Note（agent 决策记录），并更新 seam/工具/worker README、工具 schema、生成的 catalog 与包（package）依赖图、worker type-equiv 记录、单元测试以及工作流快照/header fixture（测试前置数据）。如果进度 UI 工作被立项，应从一份命名了父 agent/会话/工具调用的关联契约出发，而非原样复活这套协议。
+
+## 曾考虑的替代方案
+
+**为未来 UI 保留预建的观测词汇。** 当前形态类似 Claude Code 的动态工作流元数据，host 有意地将每个转发的 agent start 与 worker 的 end 或一个合成的终止 end 配对。移除它意味着放弃形态兼容性，使进度 UI 成为一项全新的设计任务；但现有载荷仍缺少可路由的归属信息，因此仅靠平衡的生命周期也无法在不重新设计的情况下让已命名的 ACP 消费方可行。
+
+## 验收标准
+
+- 工作流公开 seam 仅包含有生产消费方的执行、取消、结果与 dispose 契约。
+- 不再保留任何工作流事件、phase/log 协议消息、run-id 生成器、仅供进度使用的元数据、host 配对账本或 fatal 模式分支。
+- run handle 不再有 id/meta 回显，取消在同步 `start()` 返回后只有一条持有者拥有的通道。
+- parallel/pipeline 行为、上限、取消后的完全停稳、worker 隔离、结构化输出与面向模型的工作流场景保持测试覆盖。
+- 类型检查、覆盖率、快照、doc-sync（文档同步门禁）、module-graph 校验、构建与 hygiene 全部通过。
+
+## 风险
+
+这是对工作流 DSL、事件分类体系、handle 与 start request 的编译可见收缩。现有提供描述性元数据的工作流调用，以及使用 `phase`、`log` 或 label 的脚本，都必须相应精简；程序化调用方需自行将 abort source 桥接到返回的 handle；未来的观测者必须添加一个关联性更好的 seam。使工作流有用的执行语义不变。

Status: rejected — Direct runtime skill registration is an intentional extension path for third-party plugins.
+English | [中文](2026-07-12-prune-unused-skill-registry-surface.zh.md)
+
## Problem
The skill service's embedded-runtime subsystem has zero production caller of `ctx.skills.register()`. It adds a reserved `runtime` provider name, a runtime map/rank/source, duplicate policy, a second revision in cache keys, normalization, disposers, and tests alongside the provider seam every shipped skill already uses. `SkillSummary.whenToUse` and candidate/definition `path` are parsed and copied but never read by a production consumer: the model catalog renders name/description, resource loading uses `resourceBase`, and providers own their locator. The deliberately open `metadata` extension point stays.

+# Agent Note: 裁剪 skill（技能）注册表中未使用的接口
+
+Status: rejected — 直接在运行时注册 skill 是为第三方插件保留的有意扩展路径。
+
+[English](2026-07-12-prune-unused-skill-registry-surface.md) | 中文
+
+## 问题
+
+skill 服务的嵌入式运行时子系统中，`ctx.skills.register()` 没有任何生产调用方。它引入了一个保留的 `runtime` 提供方名称、一套运行时 map/rank/source、重复策略、缓存键中的第二个 revision、规范化逻辑、dispose（资源释放）器以及相应测试——而所有已交付的 skill 都只使用提供方 seam。`SkillSummary.whenToUse` 和 candidate/definition 的 `path` 被解析和复制，但没有任何生产消费方读取它们：模型目录只渲染 name/description，资源加载使用 `resourceBase`，提供方自行管理其定位器。有意开放的 `metadata` 扩展点保留不动。
+
+## 提案
+
+移除 `SkillService.register()`、`SkillRegistration`、运行时伪提供方及保留名称规则、运行时 revision/缓存分支，以及仅用于运行时的 source/rank 规范化逻辑。需要嵌入式 skill 的测试改为注册一个小型真实提供方。保留 `providerRevision` 作为进行中的发现 epoch，但已完成的目录缓存仅以 cwd 为键：每次提供方变更同步清除缓存，await 之后的 revision 比较已能阻止插入陈旧结果。从 skill 契约和本地提供方副本中移除 `whenToUse`、`SkillCandidate.path` 与 `SkillDefinition.path`，同时保留提供方的 locator/root 路径；保留 `metadata`、`disableModelInvocation`、`source`、`provider`、`locator` 和 `resourceBase`，因为它们要么是有意开放的扩展词汇，要么是生产消费的字段。
+
+同步修订 skill 系统 Agent Note（agent 决策记录）、README、JSDoc、目录文件与测试。agent（智能体）作用域的系统提示词段、工具提供方和变量明确不在本提案范围内：[agent 作用域贡献者契约](../../implemented/architecture/2026-07-08-agent-scope-contexts.md)有意允许在 `setup(agentCtx)` 期间通过 agent 拥有的上下文注册这三者，因此仓库内没有固定的作用域注册并不能证明它们未被使用。
+
+## 曾考虑的替代方案
+
+**保留面向嵌入方的运行时 skill 注册。** 这是已实现的 skill Agent Note 中有意提供的同步直接定义便利接口。一个小型提供方包装层可以在 effect 拥有的生命周期下暴露相同的嵌入数据，但它必须实现异步 `list()`/`get()`、携带提供方身份，并接受提供方的重复语义。本提案选择只保留一条统一的提供方路径，而非维护第二套排序、校验、缓存失效与查找路径。
+
+## 验收标准
+
+- skill 收集只有一条提供方驱动的路径，已完成缓存仅以 cwd 为键，revision epoch 仅用于进行中的失效检测；保留的 skill 字段要么有生产读取方，要么有记录在案的有意扩展契约。
+- agent 作用域的提示词段、变量、工具提供方、工具守卫，以及原生模式和 Code Mode 下的 structured-output 提交行为保持不变。
+- 类型检查、覆盖率、快照、doc-sync（文档同步门禁）、module-graph 校验、构建与 hygiene 全部通过。
+
+## 风险
+
+这是对预发布 skill 注册表的编译可见收缩。外部编程式 `list()`/`get()` 消费方将失去 `whenToUse` 路由提示和 candidate/definition 的 `path`；已交付的模型目录从未渲染它们，资源解析保留了显式的 `resourceBase` 加上提供方自有的不透明 locator，但这些字段并非观测等价。skill 本地 frontmatter 解析必须继续保留并校验所支持的 metadata schema，外部提供方仍可提供嵌入式、文件系统、远程或其他 skill 来源。

+Audit the Agent Note tree when the user asks to reduce or coalesce it, or when the simplification being implemented makes an owning note obsolete. Do not expand every code-simplification survey into a repository-wide note audit.
+
+Follow the deletion rule in the [Agent Note contract](../../notes/README.md#when-to-write-one); do not duplicate or weaken it here. For each candidate chain:
+
+1. Identify the current owner from shipped code, configuration, generated catalogs, package docs, newer Agent Notes, and inbound links; dates and titles are discovery hints, not proof.
+2. Classify the old note as fully or partially superseded. Any surviving behavior, current contract, durable format, compatibility obligation, or independently current rejected alternative makes it partial. Rationale that can be transferred to the current owner does not by itself make supersession partial.
+3. For full supersession, move every unique rationale, alternative, consequence, shipped verification contract, and named coverage gap into the current owner. An inventory that only describes deleted implementation mechanics is not one of those decision facts.
+4. Repair every inbound link, then delete the English note, Chinese counterpart, consistency record, and required-pair manifest entry together.
+5. Search exact filenames, symbols, config keys, event names, and wire strings after the edit. Keep partial supersessions cross-linked and current.
+
+An added-then-removed feature is a common full-supersession case. Let the removal note own the history only when the feature is absent from production code, configuration, schemas, durable or wire formats, migration, and compatibility behavior; no current documentation presents it as available; and no test exercises it as supported behavior. Removal rationale and tests that enforce absence may remain. Preserve why the feature originally existed, why that motivation no longer justified it, alternatives to full removal, the capability given up, conditions for reintroduction, and evidence that removal is complete. Old tests and implementation mechanics that verified only the deleted behavior are not current verification contracts.
+
+Reject consolidation when the removal is only one transport, default, implementation, or presentation of a feature; when persisted data or compatibility handling survives; or when the removal note does not yet carry enough rationale to prevent accidental reintroduction. A current negative design decision may legitimately need its own note even though the removed implementation is gone.

+The `dsh` command-line entry follows the `apps/` assembly tier: `apps/*` are product assemblies over `packages/*` libraries. Plain `dsh` boots the interactive TUI coding agent, `dsh -p "task"` runs one headless turn, and `dsh web` serves the browser UI.
+
+Argv is parsed once through a [Commander](https://github.com/tj/commander.js) adapter ([`src/args.ts`](src/args.ts)): one program whose default (no subcommand) is the TUI/headless surface (`--config`, `-p`/`--prompt`, `--resume`) and whose `web` subcommand is the browser UI. `src/bin.ts` switches on the resolved mode and dynamic-imports only that mode's module. `dsh --help` lists every mode and `dsh web --help` renders the web usage, `dsh --version` prints this app's version, and an unknown option or a mistyped `--resume` fails loud (stderr, exit 1) instead of misrouting. `dsh web`'s `--host`/`--port` are unvalidated pass-through overrides: the `dsh-host-webserver` schema is the single source of both the default (the shipped `cordis.yml` value when a flag is absent) and validity, and rejects a bad value at boot.
The TUI surface:
-- boots the shipped default config (`examples/tui-agent/cordis.yml`) or an explicit config argument, through [`dsh-app-boot`](../../packages/ui/app-boot/README.md);
-- resumes a persisted session with `dsh --resume <session-id>` — the form the TUI prints on exit and lists under `/resume`; the flag sets `RESUME_SESSION_ID` before boot so the shipped config rehydrates that session, and a missing or unreadable id fails loud and exits nonzero;
+- boots the shipped default config (`examples/tui-agent/cordis.yml`), or the tree named by `--config <path>` (the demo/test escape for booting an alternate example tree), through [`dsh-app-boot`](../../packages/ui/app-boot/README.md);
+- resumes a persisted session with `dsh --resume <session-id>` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized `dsh --resume <id>`; runtimes without process replacement keep the displayed command fallback. The flag provides the id on the boot context under `RESUME_SESSION_ID_KEY` (no environment variable), which the shipped config reads through `!!js`, and a missing or unreadable id fails loud instead of creating a fresh session;
- treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd;
- tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential `cordis` toolset can read and modify it;
- applies the personal overlay from `~/.dsh` (see [app-boot's Personal config](../../packages/ui/app-boot/README.md#personal-config)): `.env` fills environment gaps (ambient > project `.env` > personal `.env`), `config.yaml` patches the booted tree.
-The Web surface treats its invoking directory as the default project, loads applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opts into first-message model titles. The headless surface retains deterministic fallback titles without making the auxiliary title-model request.
+The Web and headless surfaces boot one shared composition (`cordis.yml`): both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root <path>` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. Headless differs only in listening on an OS-assigned port (parallel `dsh -p` runs never collide; the stderr-printed URL opens the live session in a browser). Both need the frontend dist and client bundles built (`pnpm run build && pnpm run build:web`).

### Agent Handles
-`ctx.agents` owns live agents and returns `AgentHandle { agent, dispose() }`. Plugins use `send()`, `steer()`, `inject()`, `cancel()`, and `whenIdle()`. The caller fiber, factory provider, and consumer handle co-own teardown through one awaited disposer.
+`ctx.agents` returns `AgentHandle { agent, dispose() }`.

-The session log is authoritative. `deriveMessages()` projects model history; raw `assistant/chunk` events remain for replay and UI fidelity. Fork, resume, transcript rendering, telemetry, and persistence derive from the same stream.

-**Model-visible ⟺ logged**: the log reconstructs every request — messages at `step/start` fronted by the header's session prefix, and headers by folding `request/header` — and the package-owned `dsh-agent-loop/invariant` can assert it through `ctx.invariants` ([reconstructability](../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md)).

-Durability is a plugin concern. Backends buffer synchronous `session/event` notifications. The semantic checkpoint policy drains requests before adapter dispatch, recorded top-level calls before tool dispatch, and complete response/result batches at `agent/post-step`; the loop retains the final turn-end checkpoint. `SessionPersistence` stores `SessionEvent` directly and metadata in `SessionHeader`; JSONL defaults to checksummed Zstandard, with SQLite under one contract ([decision](../.agents/notes/implemented/bug-fix/2026-07-21-semantic-session-checkpoints.md)).

Design `output.schema` as a useful programmatic API: return handles and fields directly, allow scalar/array/null roots when they are the honest value, and keep human explanation in `output.render`. Intermediate values are execution-local, are not persisted or prompt-truncated, and have no byte cap, so the producer's truthful acquisition bounds and process memory still matter.

A diff is derived from the args (`write` uses `oldText: null` because a call-time presenter has no prior file content); the BRIDGE, not the tool, fills the session cwd and relativizes a display-path title. If you find yourself wanting the file's old content or the working directory inside `presentCall`, stop — that belongs on the bridge or a future result-event shape, not the presenter.
-- **UI-only formatting stays out of the model result.** A fenced ` ```console ` block, a diff, a relativized path—none of these belongs in the canonical value or Native content merely to serve an editor. `output.render` owns model-facing prose; `presentationMeta` plus the card presenters own replayable UI state. A `terminal` result view carries raw output and the bridge adds fences.

# Cordis Primer
+English | [中文](cordis-primer.zh.md)
+
Cordis is the vendored plugin framework underneath the DeepSeek Harness SDK. This primer teaches the Cordis ideas a harness plugin author needs before reading the generated [events](cordis-catalog/events.md) and [services](cordis-catalog/services.md) catalogs; the [Cordis tutorial](cordis-tutorial/index.md) walks the same ideas hands-on. The vendored source and sync procedure live in [vendor/README.md](../vendor/README.md).

+# Cordis 入门
+
+[English](cordis-primer.md) | 中文
+
+Cordis 是 DeepSeek Harness SDK 底层以 vendor 方式引入的插件框架。本文介绍 harness 插件作者在阅读生成的[事件](cordis-catalog/events.md)与[服务](cordis-catalog/services.md)目录之前需要了解的 Cordis 核心概念；[Cordis 教程](cordis-tutorial/index.md)则通过实践逐一讲解这些概念。vendor 源码与同步流程见 [vendor/README.md](../vendor/README.md)。
+
+## 五个核心概念
+
+- **插件是实现 Service 的对象。** 它可以是一个带有可选 `inject` 和 `apply(ctx)` 字段的函数，也可以是一个 `Service` 子类，其生命周期由 Cordis 挂载到当前上下文中。
+- **上下文是服务的容器。** 一个服务占据一个稳定的 `ctx.<key>`（如 `ctx.tools`、`ctx.llm`、`ctx.sessions`）；其他插件通过 key 查找服务，而非导入具体实现。
+- **通过 `inject` 声明服务依赖。** 插件声明所需的服务后，会等待这些服务就绪才启动；加载顺序通过服务依赖表达，而非手动编排启动序列。
+- **类型化事件用于通信。** 服务通过 TypeScript 声明合并注册事件名，然后以 `emit`、`waterfall`（瀑布式事件）、`parallel` 或 `serial` 方式分发，分别对应监听者观察、包装、并行扇出或按序执行。
+- **注册是可逆的副作用。** 提示词片段、工具 schema、适配器、提供方和监听器通过 `ctx.effect()` 或 `ctx.on()` 安装，reload 和 teardown 时可预期地回卷。
+
+## 分发模式
+
+每个事件具有以下分发模式之一，且只能通过对应方法分发。
+
+| 模式 | 是否 await？ | 分发顺序 | 是否有返回值？ |

+
+## Cordis Waterfall 语义
+
+`ctx.waterfall` 是环绕中间件。监听器接收 `(...args, next)`。调用 `next()` 会执行下游监听器；下游返回值通过 `next()` 返回当前包装层，可由该层包装后继续向外返回。不调用 `next()` 直接返回则短路。
+
+协作式监听器通常修改一个共享的请求或决策对象，然后委托。监听器也可以选择完全替换结果，下游监听器将只看到替换后的结果。仅当监听器必须在普通注册之前运行时才使用 `prepend: true`。
+
+对于单决策事件，短路是设计意图。策略监听器在拥有决策权时可以不调用 `next()` 直接返回，而仅做标注或观察的监听器则必须委托。
+
+<a id="loader-configuration"></a>
+
+## Loader 配置
+
+`@cordisjs/plugin-include` 将 `!!js` 解析为表达式节点，但 Loader 仅在挂载插件前对条目的 `config` 做插值。条目元数据（`id`、`name`、`group`、`disabled`、`inject`、`intercept` 和 `isolate`）保持字面值；因此 `disabled: !!js ...` 是一个 truthy 对象，会始终禁用该条目。需要根据环境选择挂载哪些插件时，请使用显式的配置覆盖层。
+
+## 实践规则
+
+将行为封装为插件：工具流水线事件属于 `ctx.tools`，模型流式输出属于 `ctx.llm`，实时 agent（智能体）协调属于 `ctx.agents`。拦截和策略优先使用事件；直接能力调用优先使用服务方法。
+
+每个注册都应有对应的 disposer（dispose（资源释放）函数）：要么从 `ctx.effect()` 返回一个，要么使用 Cordis 提供的辅助方法自动处理。如果 teardown 顺序有要求，请将相关工作放在同一个 effect 中，以确保资源释放按预期顺序回卷。

+# 用户审批
+
+[English](approval.md) | 中文
+
+[dsh-user-approval](../../packages/ui/user-approval) 的用户审批 seam 回答一个问题：这个具体操作是否可以继续？它拥有共享的请求/结果词汇、`ctx.approval` 分发服务、`approval/request` 应答者 waterfall（瀑布式事件）、仅记录日志的审计事件对，以及按会话的 `ask`/`never` 策略。UI 通道可以提供人类应答者；[ACP（Agent Client Protocol）自动化桥接层](../../packages/acp/acp)为其拥有的 agent 提供一次性机器决策。调用方如 [dsh-tools](../../packages/core/tools) 和 [dsh-tool-bash](../../packages/bash/tool-bash) 消费闭合的结果，除非结果为 `allowed-once`，否则一律拒绝。
+
+源码：[`packages/ui/user-approval/src/index.ts`](../../packages/ui/user-approval/src/index.ts)
+
+## 标识与结果
+
+每个请求都会获得一个全新的 `ApprovalRequestId`。该品牌类型将 `approval/asked` 与 `approval/decided` 审计事件配对，同时不会让审批 id 与工具调用 id 或 agent（智能体）/会话 id 互换。
+
+```ts type-equiv
+/**
+ * Pairs one `approval/asked` audit event with its `approval/decided`.
+ * Service-issued (one fresh id per {@link ApprovalService.request} call).
+ */
+type ApprovalRequestId = Branded<'ApprovalRequestId'>
+```
+
+`ApprovalOutcome` 是闭合的，且默认拒绝。`allowed-once` 仅授权所询问的那一个操作；调用方对 `rejected`、`cancelled` 和 `unavailable` 均执行拒绝。缺失、无所有权、抛异常或不合规的应答者会产生 `unavailable`，而非放行。
+
+```ts type-equiv
+/**
+ * Closed approval outcomes: a one-shot grant, explicit rejection, withdrawn
+ * request, or unavailable answerer. Callers fail closed on `unavailable`.
+ */
+type ApprovalOutcome = 'allowed-once' | 'rejected' | 'cancelled' | 'unavailable'
+```
+
+## 按会话策略
+
+`ApprovalPolicy` 决定在交互式应答者运行之前发生什么。`ask` 委托给组合的应答者链，链的无应答默认值为 `unavailable`；`never` 确定性地返回 `rejected`，不分发任何应答者。生效值为会话日志中最后一条 `approval/policy` 事件，回退到服务配置。`setApprovalPolicy(session, policy)` 是唯一的写入路径，因此回放能重建覆盖值。
+
+```ts type-equiv
+/**
+ * A session's approval policy — what happens to an {@link ApprovalService}
+ * ask BEFORE any interactive answerer sees it:
+ *
+ * - `'ask'` (the default) — delegate to the composed answerers; with none
+ * composed the chain falls through to the fail-closed `'unavailable'`
+ * (exactly today's behavior).
+ * - `'never'` — never prompt anyone: every ask resolves `'rejected'`
+ * deterministically. The strict headless stance (CI, unattended runs) and
+ * the only policy value stated in the system prompt — unlike `'ask'`, its
+ * outcome is knowable without asking, so stating it cannot overclaim.
+ */
+type ApprovalPolicy = 'ask' | 'never'
+```
+
+提示词段落会声明 `never` 的确定性行为，并以服务自有的标记记录当前策略。重启后，步骤前叙述器从已记录的请求头中读取该标记，而非从部署 persona 行文中推断状态。
+
+## 审批请求
+
+`ApprovalRequest` 以足够精确的方式标识 agent 和工具操作，以便路由和审计该问题。它有意省略工具参数：应答者通过 `callId` 将提示附加到已流式输出的工具调用上，而非渲染一份可能漂移的副本。
+
+```ts type-equiv
+/**
+ * Readonly same-process permission question. `callId` links to an already
+ * presented tool call, so arguments are not duplicated here.
+ */
+interface ApprovalRequest {
+ /**
+ * The agent on whose behalf the question is asked. Routes the question (a
+ * UI answerer only answers for agents it owns) and receives the audit
+ * events on its session log.
+ */
+ readonly agent: Agent
+ /** The tool the question is about (presentation and audit). */
+ readonly toolName: string
+ /**
+ * The exact tool call being decided, when the asker has one — lets a UI
+ * attach the prompt to the tool call it already streamed.
+ */
+ readonly callId?: CallId
+ /** The asker's human-readable explanation of WHY it is asking. */
+ readonly reason?: string
+ /**
+ * Aborting withdraws the question: the request settles `'cancelled'`
+ * immediately and a late answer from a still-pending answerer is discarded.
+ */
+ readonly signal?: AbortSignal
+}
+```
+
+## 分发与审计
+
+`ctx.approval.request(req)` 要求发起请求的会话处于一个打开的轮次内。它追加 `approval/asked`，获取一个结果，追加对应的 `approval/decided`，然后以该结果 resolve。`never` 策略在服务内部、waterfall 分发之前强制执行，因此即使后来以 `prepend` 注册的应答者也无法绕过它。应答者在拥有该请求时返回结果，否则调用 `next()` 委托；第一个应答占据唯一的决策槽位。
+
+审计事件仅写入日志，不进入模型 transcript（文本记录）。模型可见的行为是调用方派生的工具结果，而请求头记录的是模型实际看到的提示词策略。服务 dispose（资源释放）时会一并移除其提示词段落和步骤前叙述器；应答者监听器独立地通过 effect 绑定到其所属插件。

# Bash Executor
+English | [中文](bash.zh.md)

The bash execution seam is split across interface ([dsh-bash](../../packages/bash/bash), `ctx.bash`), implementations ([dsh-bash-local](../../packages/bash/bash-local) and [dsh-bash-sandbox](../../packages/bash/bash-sandbox)), and consumer ([dsh-tool-bash](../../packages/bash/tool-bash), the `bash` schema). Generic background-task ids, ownership, and controls live in [tasks.md](tasks.md); this seam returns a task-free process handle.

+# Bash 执行器
+
+[English](bash.md) | 中文

+bash 执行 seam 分为接口（[dsh-bash](../../packages/bash/bash)，`ctx.bash`）、实现（[dsh-bash-local](../../packages/bash/bash-local) 与 [dsh-bash-sandbox](../../packages/bash/bash-sandbox)）和消费方（[dsh-tool-bash](../../packages/bash/tool-bash)，即 `bash` schema）。通用后台任务的 id、所有权与控制位于 [tasks.md](tasks.md)；本 seam 返回一个不含任务概念的进程句柄。
+
+源码：[`packages/bash/bash/src/types.ts`](../../packages/bash/bash/src/types.ts)
+
+## 受管 shell 环境命名空间
+
+`DSH_*` 变量是归 Harness 所有的子进程事实。面向模型的 bash 工具通过 `ctx.bashEnv` 收集它们，再经由 `BashExecRequest.dshEnv` 传递；执行器在合并当前快照之前会移除继承而来的 `DSH_*` 名称。
+
+```ts type-equiv
+/** One environment key inside the managed {@link DSH_ENV_PREFIX} namespace. */
+type DshEnvironmentKey = `${typeof DSH_ENV_PREFIX}${string}`
+```
+
+```ts type-equiv
+/** Trusted DeepSeek Harness variables for one bash execution. */
+type DshEnvironment = Readonly<Record<DshEnvironmentKey, string>>
+```
+
+## 请求与规格：`resolve()` 拆分
+
+该 seam 将**面向模型/插件的请求**（`workdir`/`timeoutMs`/`stdoutMaxBytes` 可选，由配置或请求策略补全）与执行器实际使用的**完全解析后的 spec**（这些字段均为必填）分开。工具层在二者之间调用 `ctx.bash.resolve(request)`——这具体落实了仓库的「包（package） seam 上显式优于隐式」规则：`BashExecSpec` 的读者不必猜测工作目录或输出预算来自何处。
+
+```ts type-equiv
+/**
+ * A caller's execution REQUEST: `workdir` and `timeoutMs` are optional and
+ * filled by {@link BashExecutor.resolve} from the implementation's config.
+ * This is the model-/plugin-facing shape; pass it to `resolve()` to obtain a

+ workdir?: string | undefined
+ /** Timeout override in milliseconds (implementations cap it). */
+ timeoutMs?: number | undefined
+ /**

+ dshEnv?: DshEnvironment | undefined
+ /** Resolved sandbox policy; ignored by executors that do not confine. */
+ sandboxPolicy: SandboxExecutionPolicy | undefined
+}
+```
+
+`stdin` 和 `env` 是受信任的进程内插件输入，不由 `dsh-tool-bash` 暴露。本地执行器会先清除环境中的凭据，再合并调用方显式提供的 env。见 [bash-stdin-env Agent Note（agent 决策记录）](../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-surface.md)。
+
+`stdoutMaxBytes` 同样仅供受信任插件使用。它让前台消费方能在有界解析预算内请求完整 stdout，而不会改变 stderr、后台任务或面向模型的 bash 工具的常规输出上限。
+
+## 前台运行：`BashRunResult`
+
+一次已完成（或被终止）的前台运行的结果。正交的结果**独立报告**：一个进程可以同时超时并以退出码 0 退出（因为它捕获了信号），因此 `timedOut`、`aborted`、`signal` 和 `exitCode` 各自独立为一个字段；调用方永远不会把一次被截断的运行误读为干净的成功。
+
+```ts type-equiv
+/** The outcome of one completed (or killed) foreground run. */
+interface BashRunResult {

+ exitCode: number | null
+ /** Terminating signal (e.g. 'SIGTERM'); null on normal exit. */
+ signal: NodeJS.Signals | null
+ /**

+ * short. Mutually exclusive with {@link aborted}: one fused deadline drives
+ * both the timeout and the caller's cancellation, so a timeout and an abort
+ * racing before process close report the single first-abort cause, not both
+ * (see the [timeout-library Agent Note](../../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.md)).
+ */
+ timedOut: boolean
+ /**
+ * True when the caller's `AbortSignal` was the FIRST cause to kill the command
+ * (and it was not the executor's own timeout). Mutually exclusive with
+ * {@link timedOut} — see there for the first-cause classification.
+ */
+ aborted: boolean
+ /** The effective timeout applied to this run (after defaulting/capping). */
+ timeoutMs: number
+ stdout: CollectedOutput
+ stderr: CollectedOutput
+ /** Sandbox execution facts, absent for an unsandboxed executor. */
+ sandbox?: BashSandboxInfo
+}
+```
+
+每个流是一个 `CollectedOutput`：（可能被截断的）文本加恢复信息。截断时，`text` 是**尾部**，完整流溢出到一个私有文件：
+
+```ts type-equiv
+/** One captured stream: the (possibly truncated) text plus recovery info. */
+interface CollectedOutput {
+ /** Collected text — the TAIL of the stream when truncated. */
+ text: string
+ /** True when bytes were dropped from `text`. */
+ truncated: boolean
+ /** Path to a file holding the COMPLETE stream, when truncated and available. */
+ spillPath?: string
+}
+```
+
+## 文件沙箱：`BashSandboxInfo`
+
+使用沙箱的执行器通过 `BashExecutor.sandboxMode` 暴露其已配置的模式回退值。工具层请求 [`@deepseek-ai/dsh-sandbox-policy`](../../packages/sandbox/sandbox-policy/README.md)，把每个调用会话的持久 `sandbox/mode` 覆盖值与不可变 cwd 解析为 `BashExecRequest.sandboxPolicy`；经用户批准、严格更宽松的调用只替换模式。模式/root/enforcement 词汇归 [`@deepseek-ai/dsh-sandbox` 沙箱 seam](sandbox.md) 所有；模式仅管辖文件效果。
+
+沙箱化运行会报告其模式、保守的拒绝分类与强制执行完整度。`runnerFailed` 标记命令运行前沙箱 runner 已失败；前台执行会抛出 `SANDBOX_UNAVAILABLE`，而已结束的后台进程只能通过其事实通道报告。
+
+```ts type-equiv
+/**
+ * Sandbox facts for one run, present iff a sandboxing executor handled it.
+ * Facts are reported independently of process exit status so callers can
+ * distinguish command failures from policy denials and runner failures.
+ */
+interface BashSandboxInfo {
+ /** The mode the command actually ran under. */
+ mode: SandboxMode
+ /** Whether the sandbox denied a file operation. */
+ denied: boolean
+ /** How completely the selected runner enforced the requested mode. */
+ enforcement?: SandboxEnforcement
+ /** Whether the sandbox runner failed before the command could run. */
+ runnerFailed?: boolean
+}
+```
+
+最后一项补全了这套词汇：当受限模式没有可用后端时，`ctx.sandbox` 提供方会抛出、执行器会传播由[沙箱 seam](sandbox.md)所有的 `SANDBOX_UNAVAILABLE` 错误码。选定的 runner 拒绝其 profile 时会触达同一个故障关闭的前台错误；已结束的后台任务则记录 `runnerFailed`。模型会在结果中收到拒绝/runner 事实，仅当拒绝标记指出生效模式时才得知该模式，并可通过 `sandbox_permissions` 加 `justification` 请求一次性、严格更宽松的重试；执行任何操作前，`ctx.approval` 必须批准该次确切调用。完整的策略与切换设计见[沙箱 Agent Note](../../.agents/notes/implemented/feature/2026-07-06-sandbox.md)。
+
+## 后台进程：`BashProcess`
+
+`start()` 返回不含 id 或所有者的句柄。`dsh-tool-bash` 将它适配为 `ctx.tasks.start()` 钩子；随后由通用运行时拥有任务标识与生命周期。`done` 在进程关闭时 resolve 且绝不 reject；进程结束后仍可读取，并且沙箱事实会在 `done` resolve 前写入。
+
+```ts type-equiv
+/**
+ * A background process handle returned by {@link BashExecutor.start}. It is the
+ * only access path; buffered output remains readable after exit. Executor
+ * disposal kills running processes and awaits {@link done}.
+ */
+interface BashProcess {
+ /** Process lifecycle state (settled exactly once). */
+ status: BashProcessStatus
+ /** Exit code once finished (null = killed by signal / still running). */
+ exitCode: number | null
+ /** Terminating signal name, when signal-killed. */
+ signal: NodeJS.Signals | null
+ /** Resolves when the underlying process closes (never rejects — a spawn failure settles as `killed` with the error on stderr). */
+ readonly done: Promise<void>
+ /** Sandbox facts, stamped once a confined process settles. */
+ sandbox?: BashSandboxInfo
+ /**
+ * Read output produced since the previous read (consuming — consecutive
+ * reads never re-deliver). Reads that lost data flag `lossy` and point at
+ * full-stream spill files when available.
+ */
+ readOutput(): BashProcessRead
+ /**
+ * Kill the process group. Returns false when it had already finished
+ * (no-op); idempotent.
+ */
+ kill(): boolean
+}
+```
+
+`readOutput()` 返回增量 delta 与 spill 恢复事实：
+
+```ts type-equiv
+/** One incremental {@link BashProcess.readOutput} read. */
+interface BashProcessRead {
+ /** Output produced since the previous read (stderr in a marked section). */
+ delta: string
+ /** True when truncation dropped unread bytes the delta cannot include. */
+ lossy: boolean
+ /** Full stdout spill file, when stdout truncation occurred and a safe path is available. */
+ stdoutSpillPath?: string
+ /** Full stderr spill file, when stderr truncation occurred and a safe path is available. */
+ stderrSpillPath?: string
+}
+```
+
+## 服务
+
+`BashExecutor` 拥有 `resolve`、前台 `run`、后台进程 `start` 以及 `sandboxMode` 能力事实。`dsh-bash-local` 拥有进程组、超时/中止处理、有界收集器、spill 文件、凭据清除以及 dispose（资源释放）后完全停稳。`dsh-tool-bash` 拥有面向模型的渲染，并将后台句柄适配到[通用任务运行时](tasks.md)。

# Code Runtime
+English | [中文](code-runtime.zh.md)
+
The code-execution seam — a [capability seam](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md) whose interface ([dsh-code-runtime](../../packages/code-runtime/code-runtime), `ctx.codeRuntime`) runs one model-written program against host-provided async bindings and reports what it printed and returned. Code execution is **one optional capability**, not part of the agent-loop spine — so its vocabulary lives here, not in [core.md](core.md). Backends differ by execution substrate and source language, both readonly descriptors on the service; the worker-thread backend and tool-registry consumer are specified by the [Code Mode foundation](../../.agents/notes/implemented/feature/2026-06-15-code-mode.md) and [typed-return contract](../../.agents/notes/implemented/feature/2026-07-20-code-mode-typed-tool-returns.md).

+# 代码运行时
+
+[English](code-runtime.md) | 中文
+
+代码执行 seam 是一个[能力 seam](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)：其接口（[dsh-code-runtime](../../packages/code-runtime/code-runtime)，`ctx.codeRuntime`）针对宿主提供的异步 binding 运行一段模型编写的程序，并报告其打印内容与返回值。代码执行是**一项可选能力**，不属于 agent loop（智能体循环）主干，因此其词汇定义在此而非 [core.md](core.md) 中。各后端的执行基底与源语言不同，这两项均为服务上的只读描述符；worker-thread 后端与工具注册表消费方的契约见 [Code Mode 基础设计](../../.agents/notes/implemented/feature/2026-06-15-code-mode.md)和[类型化返回契约](../../.agents/notes/implemented/feature/2026-07-20-code-mode-typed-tool-returns.md)。
+
+源码：[`packages/code-runtime/code-runtime/src/types.ts`](../../packages/code-runtime/code-runtime/src/types.ts)
+
+## 运行：请求进，结果出
+
+`CodeRunRequest` 携带**运行时所需的一切**。按照「包（package）边界处显式优于隐式」的规则，默认值（时间预算、输出上限）来自实现的已校验配置，绝不是 `run()` 内部隐藏的 `??`：
+
+```ts type-equiv
+/**
+ * One run: the program source plus everything the runtime acts on. Per the
+ * explicit-over-implicit convention, defaulting (time budgets, output caps)
+ * is the implementation's validated config — a request carries no optional
+ * tuning knobs for a hidden `??` to fill in.
+ */
+interface CodeRunRequest {
+ /**
+ * The program source, in the runtime's {@link ../index.ts | language}. It
+ * runs as the body of an async function: top-level `await` and `return`
+ * are available, and the completion value becomes
+ * {@link CodeRunResult.value}.
+ */
+ program: string
+ /** Host functions exposed to the program, one global object per namespace. */
+ bindings: CodeBindingNamespace[]
+ /**
+ * Abort the run: the runtime stops the program (hard, even mid-loop) and
+ * resolves with a {@link CodeRunFailure} of kind `'abort'`. In-flight
+ * binding calls are the CALLER's to settle — the runtime only stops asking.
+ */
+ signal?: AbortSignal
+}
+```
+
+结果将错误报告为一个**字段**，而非 `run()` 的 rejection。报告失败的程序是调用方的职责，不走异常路径（与 `BashExecutor.run` 的 resolve-on-failure 契约一致）：
+
+```ts type-equiv
+/**
+ * The outcome of one run. An error is a FIELD on a resolved result, never a
+ * rejection of `run()` — reporting a failed program is the caller's job, not
+ * an exception path.
+ */
+interface CodeRunResult {
+ /**
+ * The program's completion value (its top-level `return`), when it ran to
+ * completion and the value crossed the runtime's lossless-JSON boundary.
+ * Invalid or over-limit completions fail the run instead of substituting a
+ * rendered string; a failed or value-less run leaves this absent.
+ */
+ value?: CodeJsonValue
+ /** Text the program emitted, in order, bounded only as part of the outer result. */
+ logs: string[]
+ /** Present iff the run failed; see {@link CodeRunFailure} for the taxonomy. */
+ error?: CodeRunFailure
+}
+```
+
+## 绑定：宿主函数作为程序全局变量
+
+每个 `CodeBindingNamespace` 在程序内成为一个由异步可调用函数组成的全局对象（Code Mode 消费方传入一个：`tools`）。参数与返回值必须是无损 JSON，且跨越边界时不受 seam 层字节上限约束；运行时可以通过结构化克隆桥接它们。命名空间可以声明程序可见的错误类，而无需让运行时知道消费方的名称：运行时会注入真实构造函数，并将被拒绝的调用转为该类的实例。运行时也将绑定名视为不可信输入（`__proto__` 是普通自有属性，绝不会发生原型碰撞）：
+
+```ts type-equiv
+/**
+ * Program-visible typed rejection for one binding namespace. The runtime
+ * injects a real error constructor under `name`; rejected member calls become
+ * its instances and expose the exact member name through
+ * `memberNameProperty`. Both strings are runtime data rather than knowledge
+ * of a particular consumer such as Code Mode.
+ */
+interface CodeBindingErrorClass {
+ /** Constructor global and resulting `Error.name` (must be a usable JS identifier). */
+ name: string
+ /** Non-empty own property for the member name; cannot replace `name`, `message`, or `stack`. */
+ memberNameProperty: string
+}
+```
+
+```ts type-equiv
+/**
+ * A named group of {@link CodeBindingFunction}s the runtime exposes to the
+ * program as one global object (e.g. `tools`). Function names are arbitrary
+ * strings — a runtime must treat names like `__proto__` or `constructor` as
+ * ordinary own properties (null-prototype construction), never as prototype
+ * collisions.
+ */
+interface CodeBindingNamespace {
+ /** The global identifier the program sees (must be a valid JS identifier). */
+ global: string
+ /** The callable members, keyed by the exact name the program calls. */
+ functions: Record<string, CodeBindingFunction>
+ /** Optional program-visible typed rejection contract for this namespace. */
+ errorClass?: CodeBindingErrorClass
+}
+```
+
+```ts type-equiv
+/** A lossless JSON value transferable across the dependency-light code-runtime seam. */
+type CodeJsonValue = null | boolean | number | string | CodeJsonValue[] | { [key: string]: CodeJsonValue }
+```
+
+```ts type-equiv
+/**
+ * One host-side function exposed to the program as an async callable. The
+ * runtime bridges calls to it (possibly across a serialization boundary), so
+ * `args` and the resolution value MUST be lossless JSON. A runtime rejects a
+ * lossy or non-cloneable value with a descriptive error rather than corrupting
+ * the run. No seam-level byte cap applies to a binding resolution. A rejection
+ * of this function surfaces inside the program as a rejection of the
+ * corresponding call.
+ */
+type CodeBindingFunction = (args: unknown) => Promise<CodeJsonValue>
+```
+
+## 捕获的输出与失败分类体系
+
+日志是按发出顺序排列的纯字符串。运行时捕获程序的 console 与流输出，但通道和 console 方法的元数据不属于 seam，因为消费方只渲染文本。实现会对序列化后的外层日志数组，以及完成值或失败消息的组合载荷设置上限；固定的结果封装语法与消费方展示空白不计入这份可变载荷计量。超限会显式失败，而不会在值中插入替代内容。
+
+失败类型是**正交的结果，独立报告**（见 [defensive-patterns](../defensive-patterns.md)）：预算耗尽不是异常，中止不是超时，基底崩溃（如 OOM）也不是二者中的任何一个：
+
+```ts type-equiv
+/**
+ * Why a run failed. The kinds are orthogonal outcomes reported independently
+ * (per docs/defensive-patterns.md): a budget expiry is not an exception, an
+ * abort is not a timeout, and a substrate death is neither.
+ *
+ * - `'exception'` — the program threw or failed to parse/transform.
+ * - `'timeout'` — an implementation-owned budget expired; the message says which.
+ * - `'abort'` — {@link CodeRunRequest.signal} fired.
+ * - `'worker-exit'` — the execution substrate died without settling (e.g. OOM).
+ * - `'invalid-output'` — the completion value was not lossless JSON.
+ * - `'output-limit'` — the serialized outer logs/value/diagnostic exceeded the configured cap.
+ */
+interface CodeRunFailure {
+ /** The failure class (see the interface doc for each kind's meaning). */
+ kind: 'exception' | 'timeout' | 'abort' | 'worker-exit' | 'invalid-output' | 'output-limit'
+ /** Human-readable detail, suitable for feeding back to a model to self-correct. */
+ message: string
+}
+```
+
+## 服务
+
+`CodeRuntime`（`ctx.codeRuntime`，抽象服务，定义于 [`packages/code-runtime/code-runtime/src/index.ts`](../../packages/code-runtime/code-runtime/src/index.ts)）由 `run(request)` 加两个只读描述符组成：`language`（程序必须使用的语言，`'typescript'` 是已知值；生成语言相关展示的消费方据此切换，遇到无法展示的语言时应显式报错）和 `isolation`（执行基底，`'worker-thread'`、`'process'`、`'container'`；仅为诊断标签，**不构成安全承诺**）。实现必须保证各次运行彼此隔离（无跨运行状态），并在 dispose（资源释放）时等待系统完全停稳：teardown 完成前，进行中的运行都已终止并等待结束。

# Compaction
+English | [中文](compaction.zh.md)
+
The compaction seam — a [capability seam](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md) split like bash: interface ([dsh-compact](../../packages/compact/compact), `ctx.compact`), implementation (a backend such as [dsh-compact-basic](../../packages/compact/compact-basic)), and consumer (a `/compact` tool, deferred). Compaction is **one optional capability**, not part of the agent-loop spine — so its vocabulary lives here, not in [core.md](core.md). A tokenizer- or template-based backend is a sibling package implementing the same interface. Unlike bash, the interface necessarily depends on `dsh-session` and `dsh-llm`: its verbs act on an agent-owned `Session`, and its durable summary event uses the `ContentBlock` vocabulary (see the [compaction capability-seam Agent Note](../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md)).

+# 压缩（compaction）
+
+[English](compaction.md) | 中文
+
+压缩 seam 是一个[能力 seam](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)，与 bash 一样分为接口（[dsh-compact](../../packages/compact/compact)，`ctx.compact`）、实现（例如 [dsh-compact-basic](../../packages/compact/compact-basic) 后端）和消费方（延期实现的 `/compact` 工具）。压缩是**一项可选能力**，不属于 agent loop（智能体循环）主干，因此其词汇定义在此而非 [core.md](core.md) 中。基于 tokenizer 或模板的后端是实现同一接口的兄弟包（package）。与 bash 不同，该接口必然依赖 `dsh-session` 和 `dsh-llm`：其动词作用于 agent 所有的 `Session`，而其持久摘要事件使用 `ContentBlock` 词汇（见[压缩能力 seam Agent Note（agent 决策记录）](../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md)）。
+
+源码：[`packages/compact/compact/src/types.ts`](../../packages/compact/compact/src/types.ts)
+
+## `compact/*` 会话事件
+
+压缩通过声明合并为 [`SessionEventMap`](session.md) 扩展三种事件类型。三者都**仅写入日志**——记录压缩锁及其 provenance，绝不进入 surface。这里有意不扩展 `SurfaceEventType`（只有产生消息的事件才到达模型），因此摘要本身承载在另一条带有 `surfaceOp: { op: 'replace', start, end }` 的 `user/message` 上——这是摘要压缩执行的唯一 surface 变更。关于复用 `user/message` 为何是如实建模而非权宜之计，见对应 Agent Note。
+
+| 事件 | 载荷 | 作用 |
+|---|---|---|
+| `compact/start` | `{ turn }` | 获取日志记录的锁 |
+| `compact/summary` | `{ summary, shadowedRange, shadowedSeqs, shadowedTokenCount, provider, model, maxTokens? }` | provenance：摘要块、被遮蔽的 surface 边界对（`start`/`end` seq——位置跨度，而非数值区间）、按 surface 顺序排列的被遮蔽 seq、估算 token 数，以及摘要调用的 envelope（`provider`、`model`，若有生成上限则还包括该上限）——写入日志后，该一次性请求可由日志 + 代码重建（见可重建性 Agent Note） |
+| `compact/end` | `{ turn, error? }` | 释放锁（摘要调用抛出异常时设置 `error`） |
+
+锁括住**整个**操作：先追加 `compact/start`，然后执行摘要生成、写入 `compact/summary` 来源记录与 `user/message` 替换，最后才追加 `compact/end`。最后释放锁意味着操作中途崩溃会表现为可检测的遗留锁（有 `compact/start` 而无匹配的 `compact/end`），而非一个虚假声称压缩已完成的 `compact/end`。
+
+这些变体在 `declare module '@deepseek-ai/dsh-session'` 块内合并，因此——与其他子页面上的顶层类型不同——它们不以漂移检查的 ` ```ts type-equiv ` 块粘贴（`verify-type-equiv` 提取器只按名称匹配顶层声明）。上方的载荷表即为目录条目；权威形状请循源码链接查看。
+
+## `CompactionResult`
+
+成功压缩向调用方返回：记账事件 seq、原始摘要、被遮蔽的范围与 seq，以及估算 token 数。
+
+```ts type-equiv
+/** Result of a successful compaction operation. */
+interface CompactionResult {
+ /** The seq of the appended `compact/start` event. */

+ /** The seq of the appended `compact/end` event. */
+ endSeq: number
+ /** The summary content blocks produced by the backend. */

+ /**

+ * (`start`) and last (`end`) surface nodes of the replaced range. A
+ * surface-POSITION span, not a numeric seq interval — after a prior replace
+ * lands a fresh high-seq summary node at an older range's position, `start`
+ * can be GREATER than `end`. {@link CompactionResult.shadowedSeqs} is the
+ * authoritative set of shadowed nodes, in surface order.
+ */
+ shadowedRange: { start: number; end: number }
+ /** The seqs of all shadowed surface nodes, in surface order. */
+ shadowedSeqs: number[]
+ /** Estimated token count of the shadowed content. */
+ shadowedTokenCount: number
+}
+```
+
+## 服务
+
+自动调用方会说明策略为何运行；实现可以比普通压力更激进地处理已确认的溢出。
+
+```ts type-equiv
+/** Why automatic policy is asking a backend to consider compaction. */
+type CompactionTrigger = 'pressure' | 'context-overflow'
+```
+
+`CompactService` 暴露 `compactIfNeeded(agent, trigger, signal)` 以执行自动 `pressure` 或 `context-overflow` 策略；没有可安全执行的工作时返回 `null`。它还针对显式、两端均包含的 surface 范围暴露 `compactRegion(...)`。每个后端都使用包导出的 `COMPACT_CHECKPOINT_SOURCE` 标记其替换用的 `user/message`；消费方调用 `isCompactCheckpointSource()`，而不是把检查点识别逻辑耦合到某一个后端。实现必须把传入的 signal 转发给摘要流程。该 seam 不拥有计价 API：单例 [`ctx.tokenMeter`](token-meter.md) 直接拥有估算与回放，而 `dsh-compact-basic` 拥有保留策略、事件排序、按路由执行的摘要调用及其配置。
+
+压力压缩在串行 `agent/post-step` 中运行：此时成功的 assistant 输出、工具结果、缓冲上下文和 steering（中途引导）已持久化，但 `step/end` 尚未发生。一旦压力或规范化溢出满足条件，compact-basic 会在选择范围前调用可选的 [`ctx.toolResultPrune`](../../packages/compact/compact-tool-result-prune/README.md)，再通过 `ctx.tokenMeter` 重新测量，并且可以在不生成摘要的情况下推进 surface。失败请求的恢复在失败的步骤关闭后通过 `agent/request-error` 运行；仅当 surface replacement generation 前进时才批准一个带新编号的步骤重试，即便后续摘要工作在剪枝后抛异常亦如此；取消仍然优先。区域边界保持工具调用/结果配对，但不保持整个轮次，因此一个过大轮次中较早关闭的步骤可以被压缩。`dsh-compact-basic` 拥有阈值、保留尾部策略、溢出上限与失败处理。
+
+该 seam 导出 `toolPairingBalancedBefore(session, seq)` 与 `toolPairingBalancedAfter(session, seq)`，用于这些边缘检查。两者都会验证当前 surface 成员关系，并拒绝缺失的 seq 与遗留结果；其缓存语义由[包契约](../../packages/compact/compact/README.md#tool-pairing-boundaries)规定。
+
+## 工具结果剪枝产出
+
+可选的工具结果剪枝服务会报告每次持久内容替换以及 Unicode code point 的总减少量。其公开结果类型位于 [`compact-tool-result-prune/src/types.ts`](../../packages/compact/compact-tool-result-prune/src/types.ts)。
+
+```ts type-equiv

`AgentStatus` is `'idle' | 'running' | 'disposed'`, and `SessionId` is branded. `running` describes the driver-wide drain interval, which can span turn close, its durability checkpoint, and consecutive queued turns; it does not prove a turn is still open. `AgentOptions` is merge-extensible: core declares `provider?` and `model?` (dispatch requires both after `agent/request`). Persona belongs to `dsh-system-prompt`: an agent-scoped `deployment:persona` may shadow the global default.

+# 核心数据结构
+
+[English](core.md) | 中文
+
+本目录编目 DeepSeek Harness 的**数据结构**：每个核心类型代表什么、它的字面形状，以及完整细节在哪里。它与 [architecture.md](../architecture.md) 互补——后者描述*行为*（服务映射、会话/轮次/步骤生命周期、事件分类体系）；本页描述行为所操作的*词汇*。
+
+## 什么算"核心"
+
+harness 是一个微内核：一个极小的核心加上众多插件。大多数类型属于某一个插件或某一项能力。但有少数类型构成**主干**——agent loop（智能体循环）及其事件在*每一个*轮次中使用的语言，无论加载了哪些可选插件。这些就是"核心"。
+
+精确地说，一个数据结构是**核心**的，当且仅当满足以下条件之一：
+
+1. 它流经 agent loop 主干——循环在每个轮次中持有、派生、流式输出或记录它（`Message`、`StreamChunk`、`SessionEvent`、`Agent` 句柄本身），与当前加载了哪些插件无关；**或者**
+2. 它是插件作者面向某条流水线编写的代表性类型——`ToolDefinition`（每个工具*是什么*）。
+
+其他一切都记录在**子页面**上，而非本页。划线的规则是：*你编写、持有或接收的类型是核心；为它提供类型推导、渲染或持久化的机制是子页面细节*。因此 `ToolDefinition` 是核心，但为它提供类型推导的 `ValueSchemaSpec`/`ParameterSchemaSpec` 机制、为它提供渲染意图的 `ToolCallView`/`ToolResultView` 词汇，以及存储事件日志的 `SessionPersistence` seam 都不是——它们分别在下列子页面中。

+
+<a id="the-map--derived-union-pattern"></a>
+
+## `…Map → derived-union` 模式
+
+harness 中几乎所有可扩展的和类型都遵循同一形状：一个以判别标签为键的接口（`…Map`），联合类型由 `keyof` 派生。插件通过**声明合并**添加变体——无需修改拥有该类型的包（package）。
+
+```ts ignore-check
+// The pattern, schematically:
+interface ThingMap {
+ 'a': { kind: 'a'; /* … */ }
+ 'b': { kind: 'b'; /* … */ }
+}
+type ThingKind = keyof ThingMap // 'a' | 'b'
+type Thing = ThingMap[keyof ThingMap] // the discriminated union
+
+// A plugin extends it without touching the source package:
+declare module '@deepseek-ai/dsh-llm' {
+ interface ThingMap {
+ 'c': { kind: 'c'; /* … */ }
+ }
+}
+```
+
+六个规范 map 使用此模式；插件作者扩展它们：
+
+| Map | 包 | 派生 | 目录 |
+|---|---|---|---|
+| `ContentBlockMap` | dsh-llm | `ContentBlock` | [下文](#content-blocks-and-messages) |
+| `MessageSourceMap` | dsh-llm | `MessageSource` | [下文](#content-blocks-and-messages) |
+| `FinishReasonMap` | dsh-llm | `FinishReason` | [下文](#the-model-request-and-result) |
+| `TurnTriggerMap` | dsh-session | `TurnTrigger` | [session.md](session.md) |
+| `TurnEndReasonMap` | dsh-session | `TurnEndReason` | [session.md](session.md) |
+| `SessionEventMap` | dsh-session | `SessionEvent` | [session.md](session.md) |
+
+消费方最常 `switch` 的两个大型判别联合类型是：**`StreamChunk`**（流式协议）和 **`SessionEvent`**（日志条目）。按仓库约定，对标签做 `switch`——不要链式 `if`——这样每个分支都能窄化类型，拼错的标签会编译失败。
+
+<a id="branded-ids"></a>
+
+## 品牌化 ID
+
+跨越包边界的 ID 都经过**品牌化**——结构上是字符串，但在类型层面不可互换（不能把 `SessionId` 传给需要 `CallId` 的位置）。每种类型通过各自的工厂构造；比较、日志记录和 JSON 行为与普通字符串相同。
+
+`Branded<B>` 原语位于独立的纯类型包 [dsh-brand](../../packages/util/brand) 中（没有运行时代码，也不依赖 Harness 包），因此任何包都能品牌化其拥有的 id，而无需依赖无关的能力包。
+
+源码：[`packages/util/brand/src/index.ts`](../../packages/util/brand/src/index.ts)
+
+```ts type-equiv
+/** A string carrying a compile-time-only brand `B`. */
+type Branded<B extends string> = string & { readonly [BRAND]: B }
+```
+
+两个核心 ID 是 `CallId`（关联工具调用及其结果；dsh-llm）和 `SessionId`（活跃 agent 与持久会话共享的标识；dsh-session）。能力包也会品牌化各自的 id，例如 [tasks.md](tasks.md) 中的 `TaskId`。
+
+<a id="content-blocks-and-messages"></a>
+
+## 内容块与消息
+
+一段对话由 `Message` 组成；一条消息是一个类型化**内容块**的数组。块的联合类型从 `ContentBlockMap` 派生。
+
+源码：[`packages/llm/llm/src/types.ts`](../../packages/llm/llm/src/types.ts)
+
+```ts type-equiv
+/**
+ * Merge-extensible content blocks keyed by `type`. New core blocks must land
+ * with adapter, UI, and compaction support.
+ */
+interface ContentBlockMap {
+ 'text': TextBlock
+ 'reasoning': ReasoningBlock
+ 'tool-call': ToolCallBlock
+ 'tool-result': ToolResultBlock
+}
+```
+
+各块接口（完整字段见源码）：`TextBlock`（`text`）、`ReasoningBlock`（thinking，区别于可见文本）、`ToolCallBlock`（`id: CallId`、`name`、原始 JSON `arguments`）、`ToolResultBlock`（`toolCallId`、嵌套 `content: ContentBlock[]`、`isError?`）。`ContentBlock = ContentBlockMap[ContentBlockType]`。核心集仅限于每条交付路径都尊重的块——多模态内容（图像、音频等）没有核心块类型；需要的功能通过可合并扩展的 map 添加，同时提供适配器/UI/压缩支持。
+
+`Message` 由角色和块组成。由循环派生的 assistant 消息携带其持久提供方/模型标识，以及可选的适配器私有回放元数据：
+
+```ts type-equiv
+/** Provider ownership and adapter-private replay data for an assistant message. */
+interface AssistantProvenance {
+ /** Provider route that produced the message. */
+ provider: string
+ /** Provider model id that produced the message. */
+ model: string
+ /**
+ * Lossless-JSON adapter state needed to replay the provider response.
+ * `LlmService` exposes it to a target adapter only when that adapter instance
+ * currently owns both this historical provider and the target provider.
+ */
+ replayState?: unknown
+}
+```
+
+```ts type-equiv
+/**
+ * A single message in a conversation history. Loop-derived assistant messages
+ * always carry provenance; callers may omit it on hand-built foreign history.
+ */
+interface Message {
+ role: 'system' | 'user' | 'assistant'
+ content: ContentBlock[]
+ /** Present only on assistant messages produced by a routed adapter. */
+ provenance?: AssistantProvenance
+}
+```
+
+消息来源本身也是一个可合并扩展的和类型：
+
+```ts type-equiv
+/**
+ * Where a message (or injected content) came from.
+ * Merge-extensible sum type — plugins add their own `kind`s.
+ */
+interface MessageSourceMap {
+ user: { kind: 'user' }
+ plugin: { kind: 'plugin'; plugin: string }
+}
+```
+
+## 流式输出
+
+适配器发出原始**分片**协议；循环记录分片（回放保真度），同时将同一批分片送入 `BlockAssembler` 以重建块和消息。`StreamChunk` 是基于 `type` 的封闭判别联合——`block-start`、`text-delta`、`reasoning-delta`、`tool-call-delta`、`block-end`、`usage`、`finish`。
+
+完整联合类型、适配器契约（usage-before-finish、原始 JSON 工具参数、两条认可的错误路径）和 `BlockAssembler` 在 **[llm-streaming.md](llm-streaming.md)** 中。
+
+<a id="the-model-request-and-result"></a>
+
+## 模型请求
+
+一次模型调用是一个完全组装好的 `GenerateOptions`。适配器以原始 `StreamChunk` 流作答；消费方用 `BlockAssembler` 组装它（见 [llm-streaming.md](llm-streaming.md)）。
+
+源码：[`packages/llm/llm/src/types.ts`](../../packages/llm/llm/src/types.ts)
+
+提供方与模型发现使用小型、提供方无关的描述符。模型目录仅供参考：路由仍以已注册提供方为键，适配器也可以接受未列出的模型 id。
+
+```ts type-equiv
+/** Display metadata for one registered provider route. */
+interface LlmProviderInfo {
+ /** Provider route key used by {@link GenerateOptions.provider}. */
+ id: string
+ /** Human-readable provider name for selectors and diagnostics. */
+ name: string
+}
+```
+
+```ts type-equiv
+/** One adapter-discovered model; catalog membership is advisory, not request validation. */
+interface LlmModelInfo {
+ /** Provider route that owns this model entry. */
+ provider: string
+ /** Model id passed to {@link GenerateOptions.model}. */
+ id: string
+ /** Human-readable model name for selectors. */
+ name: string
+ /** Optional user-facing distinction from otherwise similar models. */
+ description?: string
+}
+```
+
+对正确性敏感的模型容量与参考目录分开查询，并归服务该确切路由的适配器所有。
+
+```ts type-equiv

+ contextWindow: number
+}

+`GenerateOptions.tools` 携带 `ToolSchema`——工具的 JSON Schema 描述，发送给模型。它声明在 dsh-llm（而非 dsh-tools）中，正是因为它是循环每一步组装请求的一部分：
+
+```ts type-equiv
+/**
+ * JSON-schema description of a tool, as sent to the model.
+ *
+ * Declared here (not in dsh-tools) because it is part of {@link GenerateOptions};
+ * dsh-tools' ToolDefinition and dsh-system-prompt's PromptAssembly both import
+ * it from this package.
+ */
+interface ToolSchema {
+ name: string
+ description: string
+ /** JSON Schema object for the arguments. */
+ parameters: Record<string, unknown>
+}
+```
+
+面向模型的 `ToolSchema` 是协议格式；产出它的已注册 `ToolDefinition`（schema + `execute`）在 [tools.md](tools.md) 中。
+
+### 请求信封：`LlmCallConfig` 与记录的 header
+
+循环从已记录状态构建每个请求。`EpochHeader` 通过完整的 `request/header` 快照记录调用配置、渲染后的提示词、权威返回工具顺序（由 `toolOrder` 配置；未配置时按字典序）以及会话前缀。结合派生历史，请求便可由会话日志重建。见 [session.md](session.md#the-request-header-event-requestheader) 与[可重建性 Agent Note（agent 决策记录）](../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md)。
+
+`agent/request` 接收冻结的调用配置种子，并可返回替代值以切换提供方、模型或采样参数。`agent/session-prefix` 为每个循环实例组合一次仅用于请求的 prefix 消息，header 记录实际使用的确切结果。到达 `llm/stream` 的请求会被深度冻结，因此变更会抛异常；请求还携带进程本地循环标识，使观察者不会把单独记录的冻结辅助调用误认成对话请求。
+
+在协议格式上，循环构建的请求按此顺序读取：`system` 槽位（渲染后的提示词组装）→ `messagePrefix`（冻结的会话前缀）→ 派生历史——边界快照，其尾部在轮次首步是最新的 `user/message`，在后续步骤是上一步的工具结果。前缀从不进入派生历史；它的持久记录是 header 事件，开发不变式针对每个循环构建的请求精确重算此等式。
+
+FIXME(call-config-shape)：重新审视此类型的精确定义——出于缓存目的，哪些字段确实属于 epoch 层级（`model` 肯定属于；采样标量目前出于谨慎放在这里），以及适配器需要时，提供方特有的额外项（推理选项、额外 body 参数）应归属何处。
+
+```ts type-equiv
+/**
+ * Provider + model + sampling scalars of one conversation's requests. Every field maps
+ * 1:1 onto the same-named `GenerateOptions` field; the loop builds requests
+ * from the logged header rather than accepting these per call.
+ */
+interface LlmCallConfig {
+ provider: string
+ model: string
+ temperature?: number
+ maxTokens?: number
+ stop?: string[]
+}
+```
+
+## 会话
+
+`Session` 是一份类型化 `SessionEvent` 的**仅追加日志**——唯一的真源。LLM（大语言模型）消息历史从日志*派生*（`deriveMessages()`），而非单独存储。事件词汇从 `SessionEventMap` 派生：
+
+源码：[`packages/core/session/src/types.ts`](../../packages/core/session/src/types.ts)
+
+```ts type-equiv
+/**
+ * One immutable entry in the session log.

+## Agent 句柄
+
+`Agent` 是每个插件（UI、钩子、orchestrator）面向编程的 surface。具体实现为 dsh-agent-loop 包内部细节；循环外没有任何组件依赖它。
+
+源码：[`packages/core/agent/src/types.ts`](../../packages/core/agent/src/types.ts)
+
+```ts type-equiv
+/**
+ * Options for {@link Agent.followup}, {@link Agent.queue}, and {@link Agent.steer}.
+ * An omitted source attests direct human input as `{ kind: 'user' }` and may
+ * authorize policy consumers, so non-human producers must label their content.
+ */
+interface SendOptions {
+ source?: MessageSource
+ /**
+ * Model-facing contexts captured with this inbox item. A queued prompt exposes
+ * them through the default `agent/prompt-submit` allow decision, while steering
+ * records them directly at its next checkpoint.
+ */
+ contexts?: HookContext[]
+ /** Opaque JSON state retained on the durable message but hidden from the model. */
+ meta?: JsonValue
+}
+```
+
+```ts type-equiv
+/** Options specific to durable synthetic context injection. */
+interface InjectOptions {
+ /** Defaults to `{ kind: 'plugin', plugin: '' }`; non-human producers should identify themselves. */
+ source?: MessageSource
+ /** Opaque JSON state retained on the durable message but hidden from the model. */
+ meta?: JsonValue
+}
+```
+
+高级接收形式会显式给出所有默认值，并禁止为注入附加上下文：
+
+```ts type-equiv
+/**
+ * Fully specified input for {@link Agent.send}. Unlike the intent-named
+ * helpers, this form applies no defaults: callers provide content, source,
+ * contexts, metadata (including explicit `undefined`), target, and wakeup.
+ * The union excludes attached contexts from non-waking next-step injection.
+ */
+type ResolvedAgentInput = {
+ content: ContentBlock[]
+ source: MessageSource
+ meta: JsonValue | undefined
+} & (
+ | { target: 'next-turn'; wakeup: boolean; contexts: HookContext[] }
+ | { target: 'next-step'; wakeup: true; contexts: HookContext[] }
+ | { target: 'next-step'; wakeup: false; contexts: [] }
+)
+```
+
+FIFO 投递方法返回不透明的 `AgentMessageId`，该 id 在同一条消息的各个 `agent/inbox/*` 事件中保持稳定。注入也返回 id，但会绕过这些事件：
+
+```ts type-equiv
+/**
+ * Opaque id assigned to one accepted agent input. FIFO inputs carry the same id
+ * on their `agent/inbox/*` events; injection bypasses those events.
+ */
+type AgentMessageId = Branded<'AgentMessageId'>
+```
+
+`agent/inbox/*` 实时事件承载一条已接收的消息；注入绕过两个 FIFO，从不出现在这些事件中：
+
+```ts type-equiv
+/**
+ * One accepted FIFO message, carried by the `agent/inbox/*` live events. `id`
+ * is the value returned by the accepting helper or {@link Agent.send},
+ * stable across this message's enqueue, dequeue, and discard events. Source
+ * defaults, when applicable, are already applied, so these are the exact values
+ * the item was accepted with.
+ * `steering` is true for an item drained between steps; otherwise it is claimed
+ * at a turn boundary. `SendOptions.meta` is intentionally omitted: it is durable
+ * model-hidden state that lands on the eventual `user/message`/
+ * `steering/message`, not live-event routing data.
+ */
+interface AgentMessage {
+ /** The id returned by the accepting helper or {@link Agent.send}. */
+ id: AgentMessageId
+ content: ContentBlock[]
+ source: MessageSource
+ contexts: HookContext[]
+ /** Whether the item joined the steering FIFO rather than the queued FIFO. */
+ steering: boolean
+ /** Whether the item wakes the driver or requests another step. */
+ wakeup: boolean
+}
+```
+
+```ts type-equiv
+/** Options for {@link Agent.cancel}. */
+interface CancelOptions {
+ /**
+ * Preserve queued and steering inbox items instead of discarding them. The
+ * active turn is still aborted, but un-started and pending work survives for a

+ */
+ keepInbox?: boolean
+}
+```
+
+```ts type-equiv
+/** Stable runtime cause accepted by {@link Agent.cancel}. */
+type AgentCancelCause =
+ | { readonly kind: 'user' }
+ | { readonly kind: 'parent' }
+```
+
+结构化 `Agent` 接口公开四个按意图命名的辅助方法，以及接受完全解析输入的方法。具体驱动器只需实现一次这套路由矩阵，每个辅助方法提供其固定路由与默认值。
+
+```ts type-equiv
+/** Public agent handle; its concrete implementation is internal to `@deepseek-ai/dsh-agent-loop`. */
+interface Agent {

+ /** Resolve at idle quiescence; disposal waits for driver exit rather than only the status transition. */
+ whenIdle(): Promise<void>
+}
+```
+
+`AgentStatus` 为 `'idle' | 'running' | 'disposed'`，`SessionId` 是品牌类型。`running` 描述整个驱动器的排空区间，可能跨越轮次关闭、其持久化检查点以及连续的排队轮次；它不能证明某个轮次仍然打开。`AgentOptions` 可合并扩展：core 声明 `provider?` 与 `model?`（在 `agent/request` 后，分发要求两者都存在）。Persona 归 `dsh-system-prompt` 所有：agent 作用域的 `deployment:persona` 可以遮蔽全局默认值。
+
+cause 是由 TypeScript 强制约束的同进程输入。活跃的 `TurnCancellation` 持有者会把其判别字段复制到仅运行时的 `AbortSignal.reason`，并在发布 `turn/end` 前退役；冻结后的 `AbortSignal.reason` 仍可读取。`agentInterruptReasonOf(signal)` 无需查询环境中的 initiator 状态，即可识别 `user`、`parent` 与仅用于生命周期的 `disposed`。持久 `turn/end` 保留粗粒度 `{ kind: 'aborted' }` 结果；若需记录请求 provenance，应使用单独的持久事件，而不是让终态结果承担额外含义。
+
+[事件分类](../architecture.md#event)拥有 `agent/*` 生命周期、检查点与 waterfall（瀑布式事件）契约。轮次和步骤边界是持久会话事件，而不是 agent emit。
+
+## 发起 Agent
+
+`ctx.agents` 携带的进程本地 initiator 就是上面的确切 `Agent`，不是单独的 frame 或复制的标识。环境中存在该值既不能证明存活，也不代表授权；其生命周期与边界规则由 [initiator 作用域决策](../../.agents/notes/implemented/architecture/2026-07-15-agent-initiator-scope.md)规定。
+
+## 拦截决策
+
+每个 `agent/*` 拦截 waterfall 都返回一个小型、特定于 seam 的类型化联合——统一的 Decision 惯用形状（[tools.md](tools.md) 中工具 seam 的 `PreToolDecision`/`PostToolDecision` 也采用相同形状）。CC/Codex 钩子桥接层把其 `permissionDecision`/`decision`/`continue`/`additionalContext` 字段映射到这些联合上；原生插件则直接返回它们。提示词决策与工具后决策共享一种面向模型的上下文形状 `HookContext`，它必须携带 `source`（缺少 source 会默认成 `{kind:'user'}`，从而把插件上下文错标为用户提示词）。其中的 `content` 作为 user-role 输入逐字到达模型，而 JSON `meta` 持久保存插件状态但不向模型暴露。未指定放置方式或指定为 `separate` 时，上下文会成为一条注入的 `user/message`（来源类别为插件或 goal）；`prompt-prefix` 放置方式可用于提示词和 steering 收件箱附件，会在同一条消息中把上下文置于最终生效的请求之前。两种决策都携带 `additionalContexts[]`，使每一项保留各自的 provenance、元数据与放置方式。Continuation reason 则是 steering 消息，并有意使用更窄的 content/source 形状。
+
+源码：[`packages/core/agent/src/types.ts`](../../packages/core/agent/src/types.ts)
+
+```ts type-equiv
+/** Model-facing context injected by a listener or atomically attached to one inbox message. */
+interface HookContext {
+ content: ContentBlock[]
+ source: MessageSource
+ /**
+ * Model placement. Absent or `separate` records an independent injected
+ * `user/message`; `prompt-prefix` prepends this context and a stable
+ * request delimiter to the same user-role message as its attached prompt.
+ */
+ placement?: 'separate' | 'prompt-prefix'
+ /** Opaque JSON state retained in the session event but hidden from the model. */
+ meta?: JsonValue
+}
+```
+
+`agent/prompt-submit` 返回 `PromptDecision`（允许该轮次已领取的排队消息——可选地改写其 `content` 或附加 `additionalContexts`——或者记录 `prompt/blocked` 并以 `rejected` 结束这个零步骤轮次）：
+
+```ts type-equiv
+/**
+ * Prompt interception result. `allow.content` replaces the prompt. Each
+ * `additionalContexts` entry follows its declared placement: separate context
+ * message by default, or a prefix inside the prompt's user-role message.
+ * `block` records a durable `prompt/blocked` and ends the claimed prompt's
+ * zero-step turn as rejected. An `allow` returned by a listener is
+ * authoritative: a listener wrapping `next()` preserves downstream `content`
+ * and `additionalContexts` unless it intentionally replaces them.
+ */
+type PromptDecision =
+ | { kind: 'allow'; content?: ContentBlock[]; additionalContexts?: HookContext[] }
+ | { kind: 'block'; reason: string }
+```
+
+`agent/turn-continuation` 返回 `ContinuationDecision`（步骤有工具调用或注入了 steering 时，循环默认为 `continue`，否则为 `stop`；`continue` 的 `reason` 会记录为同一轮次中下一个步骤的 steering，因此不携带上下文元数据——即类型化 `/goal` 模式）：
+
+```ts type-equiv
+/** Turn continuation override; a continue reason is recorded as next-step steering in the same turn. */
+type ContinuationDecision =
+ | { action: 'stop' }
+ | { action: 'continue'; reason?: { content: ContentBlock[]; source: MessageSource } }
+```
+
+`agent/request-error` 接收确切的原始 `RequestError`、其不可变 `LlmFailure`、在连续序列中已批准另一次请求的不可变失败列表、轮次信号以及 `next()`。恢复插件按 `failure.code` 路由，而不是按活跃错误的消息路由；每项策略只统计自身的 code，一次成功请求会清空历史：
+
+```ts type-equiv
+/** Model-request failure with an optional machine-routable provider code. */
+type RequestError = Error & { code?: string }
+```
+
+它返回 `RequestErrorDecision`；`retry` 在恢复 listener 的持久变更之后打开一个带新编号的步骤，而 `fail` 在 `turn/end` 上保留结构化失败：
+
+```ts type-equiv
+/** Failed-request recovery decision; `retry` opens another numbered step while listeners delegate by calling `next()`. */
+type RequestErrorDecision = { action: 'fail' } | { action: 'retry' }
+```
+
+`agent/post-step` 会在 assistant 输出、真实或合成的工具结果、缓冲上下文与 steering 持久化之后、`step/end` 之前被 await。被取消的工具批次在排空后携带 aborted signal 到达这里；其签名为 `(agent, turn, step, signal)`，可回放事实保留在会话日志中，而不是瞬态 payload 中。
+
+`agent/turn-stop` 返回仅停止的 `ContinuationStop` 子集或 `undefined`。循环在折叠普通决策、其 reason 和待处理 steering 之后调用此串行检查点；stop 是终态，会丢弃待处理的 steering。
+
+```ts type-equiv
+/**
+ * The terminal subset of {@link ContinuationDecision}. A listener on
+ * `agent/turn-stop` returns this to make the already-composed continuation
+ * outcome terminal; `undefined` abstains.
+ */
+type ContinuationStop = Extract<ContinuationDecision, { action: 'stop' }>
+```
+
+`agent/session-start` 携带 `SessionStartSource`（会话生命周期为何开始；桥接层据此匹配其 SessionStart）：
+
+```ts type-equiv
+/** Why a session lifecycle began; seeded creates are `startup`, while persisted loads are `resume`. */
+type SessionStartSource = 'startup' | 'resume' | 'clear' | 'compact'
+```
+
+`agent/session-prefix` 在每个循环实例中组合一次 `Message[]`。深度冻结的结果被记录在请求 header 中，并前置于每次派生历史，使其成为会话稳定开场白的归属。恢复的实例会重新组合；会话中途的变更使用仅追加的上下文通道。该 waterfall 直接返回内容，因为它是贡献而非决策。
+
+## `ToolDefinition`
+
+唯一属于核心的流水线编写类型：每个已注册工具*是什么*——一个面向模型的 `ToolSchema` 加上一个 `execute` 函数，以及可选的最终内容回调与 UI 回调。工具作者很少手动构造它（`defineTool` DSL 会用类型化参数构建），但它是注册表持有、循环分发所经过的契约。
+
+其完整字段、`defineTool`/`ValueSchemaSpec`/`ParameterSchemaSpec` 类型化 schema DSL、`ToolExecution`/`ToolExecutionResult` waterfall 形状，以及工具展示 UI 词汇在 **[tools.md](tools.md)** 中。

# Filesystem
+English | [中文](filesystem.zh.md)
+
The optional filesystem capability has four parts: [dsh-fs](../../packages/fs/fs) owns `ctx.fs` and atomic text operations with optional version guards, [dsh-fs-local](../../packages/fs/fs-local) implements local disk, [dsh-fs-policy](../../packages/fs/fs-policy) adds observed-state and freshness rules through events rather than a service, and [dsh-tool-fs](../../packages/fs/tool-fs) directly executes model-facing read/write/edit calls and renders windows. It is outside the agent-loop spine; alternate backends do not change policy or tool schemas.
The model is **additive, not subtractive**: `ctx.fs` alone is a complete, unconstrained text-storage seam (`write` unconditionally creates-or-overwrites, `edit` unconditionally replaces literal text). `dsh-fs-policy` is a plugin that *adds* policy on top by deciding the `fs/*` waterfalls; removing it leaves the bare provider rather than breaking the tool, because the tool is not method-coupled to the policy. A deployment that loads `dsh-tool-fs` is expected to also load `dsh-fs-policy` so the default behavior is read-before-write/edit.

+# 文件系统

+
+可选的文件系统能力由四个部分组成：[dsh-fs](../../packages/fs/fs) 拥有 `ctx.fs` 以及带可选版本守卫的原子文本操作；[dsh-fs-local](../../packages/fs/fs-local) 实现本地磁盘后端；[dsh-fs-policy](../../packages/fs/fs-policy) 通过事件（而非服务）添加观测状态与新鲜度规则；[dsh-tool-fs](../../packages/fs/tool-fs) 直接执行面向模型的 read/write/edit 调用并渲染窗口。它位于 agent loop（智能体循环）主干之外；替换后端不会改变策略或工具 schema。
+
+该模型是**加法式而非减法式**的：`ctx.fs` 本身就是一个完整、无约束的文本存储 seam（`write` 无条件创建或覆盖，`edit` 无条件替换字面文本）。`dsh-fs-policy` 是一个插件，通过裁决 `fs/*` waterfall（瀑布式事件）在上层*叠加*策略；移除它只会暴露裸提供方，而不会破坏工具，因为工具与策略之间没有方法级耦合。加载了 `dsh-tool-fs` 的部署通常也应加载 `dsh-fs-policy`，使默认行为为「先读后写/编辑」。
+
+提供方源码：[`packages/fs/fs/src/types.ts`](../../packages/fs/fs/src/types.ts) 与 [`packages/fs/fs/src/index.ts`](../../packages/fs/fs/src/index.ts)。策略源码：[`packages/fs/fs-policy/src/types.ts`](../../packages/fs/fs-policy/src/types.ts)。读取渲染源码：[`packages/fs/tool-fs/src/read-render.ts`](../../packages/fs/tool-fs/src/read-render.ts)。
+
+## 目标标识与元数据（提供方 seam）
+
+每个操作首先将用户提供的路径解析为不透明的后端目标。消费方可以显示 `displayPath`，但禁止解析 `targetKey`（一个品牌化的不透明 id），也不得假设它是本地绝对路径。
+
+```ts type-equiv
+/**
+ * A path resolved by a backend into a stable identity. `resolve()` produces
+ * this; every other operation takes it.
+ */
+interface FsTarget {

+ /**
+ * Path for model/UI-facing output. May be a local absolute path,
+ * workspace-relative path, or remote URI depending on the backend.
+ */
+ displayPath: string
+}
+```
+
+后端拥有文件版本 token，即 write/edit 所守卫的新鲜度 token。策略插件存储它们以进行陈旧检查；消费方不解释其内容。两个 id 都是品牌化的不透明字符串。
+
+```ts type-equiv
+/**
+ * Opaque key for stale guards and target lookup. The local backend uses a
+ * realpath-like string; a remote backend might use a workspace URI or file id.
+ * Consumers MUST NOT parse it or assume it is a local absolute path.

+```
+
+```ts type-equiv
+/**

+ * interpret this token.
+ */
+type FsVersion = Branded<'FsVersion'>
+```

+`stat` 返回元数据（从不返回内容），目标不存在时返回 `undefined`。`type` 让工具在读取前拒绝目录或特殊文件；`size` 让工具无需通过失败探测即可选择 `readText` 还是 `streamText`。
+
+```ts type-equiv
+/**
+ * Metadata about a target — what {@link FileSystem.stat} returns. Lets the
+ * policy layer reject directories/special files before reading and choose
+ * `readText` vs `streamText` from `size` without probing by failure. `version`
+ * is the freshness token. `undefined` from `stat` means the target is absent.
+ */
+interface FsInfo {
+ /** Opaque freshness token of the target right now. */
+ version: FsVersion
+ /** Whether the target is a regular file, a directory, or something else. */
+ type: 'file' | 'directory' | 'other'
+ /** Byte size of a regular file, when the backend can report it. */
+ size?: number
+}
+```
+
+`lstat` 是路径层级、不跟随链接的元数据原语。它接收路径而不是 `FsTarget`，因为 `resolve` 会有意跟随 symlink 以产生稳定标识；需要检查信任边界的消费方可以先调用 `lstat`，在解析前拒绝 `symlink`。
+
+```ts type-equiv
+/**
+ * Metadata about a path without following the final path component when it is a
+ * symbolic link. Unlike {@link FsInfo}, this path-level probe can report
+ * `symlink` so consumers with trust-boundary rules can reject repository-owned
+ * links before resolving a target.
+ */
+interface FsPathInfo {
+ /** Opaque freshness token of the path entry right now. */
+ version: FsVersion
+ /** Whether the path entry is a regular file, directory, symlink, or other. */
+ type: 'file' | 'directory' | 'symlink' | 'other'
+ /** Byte size of the path entry, when the backend can report it. */
+ size?: number
+}
+```
+
+`listDir` 按稳定的名称顺序返回直接子条目。每个条目携带子项的 basename、类型、已解析目标，以及后端能报告时的廉价元数据。它禁止读取文件内容，因此 `size` 仅用于普通文件，`version` 来自元数据。已损坏或已消失的子项可以作为 `other` 返回且不带元数据；列出或解析子项元数据时的权限或后端 I/O 失败会以 `FS_PERMISSION_DENIED` 或 `FS_IO_ERROR` 使整个列表操作失败。
+
+```ts type-equiv
+/**
+ * One direct child returned by {@link FileSystem.listDir}. Listing returns
+ * metadata and resolved targets only; it must not read file contents.
+ */

+ /** Resolved child target for follow-up operations. */
+ target: FsTarget
+ /** Opaque freshness token when the backend can report metadata cheaply. */
+ version?: FsVersion
+ /** Byte size of a regular file, when the backend can report it. */
+ size?: number
+}
+```
+
+## 写入与编辑守卫（提供方 seam）
+
+`writeText` 和 `editText` 的版本守卫都是可选的：省略它执行无条件（裸提供方）变更，提供它则启用守卫。`writeText` 的守卫是 `FsWriteIntent`：`createIfAbsent` 在目标缺失时创建，目标已存在时以 `FS_NOT_OBSERVED` 拒绝；`replaceIfVersion` 仅在目标存在且版本匹配时替换，否则报 `FS_STALE_VERSION`。省略 `expected` 则无条件创建或覆盖。联合类型本身只包含两种有守卫的意图；「无守卫」通过省略表达，因此 write 和 edit 共享同一个对称的 `expected?` 形状。
+
+```ts type-equiv
+/**
+ * Guarded write intent. `createIfAbsent` rejects an existing target with
+ * `FS_NOT_OBSERVED`; `replaceIfVersion` rejects absence or mismatch with
+ * `FS_STALE_VERSION`. Omitting the intent from `writeText` means unconditional
+ * create-or-overwrite, not a third union arm.
+ */
+type FsWriteIntent =
+ | { kind: 'createIfAbsent' }
+ | { kind: 'replaceIfVersion'; version: FsVersion }
+```
+
+```ts type-equiv
+/** Outcome of a full-file write. */
+interface FsWriteOutcome {
+ /** Whether the write created a new file or replaced an existing one. */
+ operation: 'create' | 'update'
+ /** Opaque version of the file after the write. */
+ version: FsVersion
+ /**
+ * The file's content BEFORE the write, or `null` when the file did not exist
+ * (a create) or was undiffable (binary/non-UTF-8). LF-normalized storage text
+ * (the diff basis), never a diff — a consumer computes the result-time
+ * contextual diff from `before`/`after` when `before` is present, else falls
+ * back to a whole-file diff.
+ */
+ before: string | null
+ /** The file's content AFTER the write, LF-normalized to share `before`'s diff basis. */
+ after: string
+}
+```
+
+`editText` 是提供方级别的变更操作，而非在别处组合的 `read` 加 `write`。带守卫时，它在字面匹配之前先验证预期版本（因此对陈旧内容的编辑报 `FS_STALE_VERSION`，而非对更新内容的匹配失败）；不带守卫时，它编辑当前内容。无论哪种路径，它都应用替换并原子写入——将匹配、行尾处理、陈旧检查和原子替换保持在一个变更临界区内——目标缺失时两条路径都报 `FS_STALE_VERSION`。
+
+```ts type-equiv
+/** A literal-replacement edit request. */
+interface FsEditRequest {
+ /** Literal non-empty text to replace. Must match exactly (after line-ending normalization). */
+ oldString: string
+ /** Literal replacement text. An empty string deletes the matched text. */
+ newString: string
+ /** Replace every match instead of requiring exactly one. */
+ replaceAll: boolean
+}
+```
+
+```ts type-equiv

+interface FsEditOutcome {
+ /** Opaque version of the file after the edit. */
+ version: FsVersion
+ /**
+ * The file's content BEFORE the edit. Raw storage text (LF-normalized by the
+ * backend), never a diff — a consumer computes the result-time contextual diff
+ * (the applied hunk with context) from `before`/`after`.
+ */
+ before: string
+ /** The file's content AFTER the edit. */
+ after: string
+}
+```
+
+## fs 策略事件（提供方 seam 词汇）
+
+`dsh-fs` 拥有三个事件，由工具分发、策略插件监听，使发射方（`dsh-tool-fs`）与监听方（`dsh-fs-policy`）共享词汇，而发射方无需依赖策略插件。它们只携带 `dsh-fs` 词汇加一个不透明的 `object` actor，不含面向模型的概念，也不含 agent/会话所有者结构。
+
+`fs/write-intent` 与 `fs/edit-intent` 是**单槽决策 waterfall**：工具分发时附带一个默认 thunk（返回 `undefined`，即裸提供方），监听方完全决策而不调用 `next()`。该槽按注册顺序先到先得——由策略插件占据是部署约定，而非强制不变式。`fs/observed` 是一个即发即弃的记录事件，通过普通 `ctx.emit` 分发；其监听方必须是同步的、仅产生副作用，因为工具不守卫该 emit——抛异常的监听方会在一次已成功的变更上表现为工具的 `isError` 结果。生成的目录在 [events.md](../cordis-catalog/events.md) 中展示确切签名。
+
+## 执行上下文（策略插件）
+
+策略插件只需要足够的执行上下文，通过收窄 `fs/*` 事件携带的不透明 `object` actor 来推导观测状态的所有者。`ToolExecution` 满足此形状，因此 `dsh-tool-fs` 将其执行对象作为 actor 直接传递，而无需让 `dsh-fs-policy` 导入工具、agent 或会话包（package）。
+
+```ts type-equiv
+/**
+ * Minimal structural view of a tool execution the policy plugin needs to derive
+ * an observed-state owner. `@deepseek-ai/dsh-tools`' `ToolExecution` satisfies
+ * this shape, so the tool passes its `exec` straight through as the opaque
+ * `object` actor on the `fs/*` events; this plugin narrows that actor to this
+ * shape without importing `dsh-tools`, `dsh-agent`, or `dsh-session`.
+ *
+ * The owner is `agent.session` when present. It is treated as an opaque object
+ * identity (a `WeakMap` key); this package never reads any of its fields.
+ */
+interface FsPolicyExec {
+ /** The agent on whose behalf the call runs, when there is one. */
+ agent?: {
+ /** The session that owns observed-file state, used as an opaque key. */
+ session?: object
+ }
+}
+```
+
+## 读取结果（消费方 / 读取渲染）
+
+文本读取受行窗口、字节上限和后端限制约束。达到字节上限后，扫描仍会继续，但不再保留更多行，因此 `totalLines` 仍为精确值。面向模型的 `read` 工具渲染的结果纯粹是展示性的；不存在 `full`/`partial` 视图区分——授权基于新鲜度（工具直接用 stat 的版本 emit `fs/observed`），因此任何窗口化读取在文件未变时都能授权后续的 write/edit。读取窗口化与此结果形状位于 `dsh-tool-fs`（拥有读取操作的执行器）中，而非策略插件中。
+
+```ts type-equiv
+/** Outcome of a bounded text read — what {@link formatReadOutput} renders. */
+interface FileReadOutcome {
+ /** 1-based first line requested. */
+ offset: number
+ /** Returned lines, already numbered. */
+ lines: FileTextLine[]
+ /** Exact total line count in the file. */
+ totalLines: number
+ /** Whether selected output hit the byte cap. */
+ truncatedByBytes?: true
+}
+```
+
+## 已观测文件状态（策略插件）
+
+已观测状态是 `dsh-fs-policy` 插件内部持有的 `WeakMap<owner, Map<targetKey, { version }>>`。**当且仅当**所有者已读取、写入或编辑过该目标时（每次成功都 emit `fs/observed`），条目才存在，因此其存在本身就是先前观测的记录——没有单独的 `hasRead` 标志，也没有视图区分。所有者从事件 actor 推导（通常是 `exec.agent.session`），被视为不透明且从不读取。成功的 read/write/edit 会刷新该所有者对应的已记录版本；dispose（资源释放）时丢弃全部数据（HMR（热模块替换）安全）。
+
+## 错误分类体系（提供方 seam）
+
+文件系统故障使用稳定的 `FsErrorCode` 字符串，由 `FsError`（`HarnessError`）携带。工具注册表在错误结果上保留 `{ name, code }`，使重试、权限和 UI 层可以按 code 分支而无需解析文本。
+
+```ts type-equiv
+/**
+ * Stable, machine-routable codes for filesystem failures. Carried on
+ * {@link FsError}; the tool registry surfaces `{ name, code }` on `isError`
+ * results so retry/permission/UI layers can branch without parsing messages.
+ */
+type FsErrorCode =
+ | 'FS_NOT_FOUND'
+ | 'FS_NOT_DIRECTORY'
+ | 'FS_NOT_TEXT'
+ | 'FS_NOT_REGULAR_FILE'
+ | 'FS_PERMISSION_DENIED'
+ | 'FS_SANDBOX_DENIED'
+ | 'FS_IO_ERROR'
+ | 'FS_STALE_VERSION'
+ | 'FS_NOT_OBSERVED'
+ | 'FS_AMBIGUOUS_EDIT'
+ | 'FS_EDIT_NOT_FOUND'
+ | 'FS_ABORTED'
+```
+
+目录列表使用 `FS_NOT_DIRECTORY`、`FS_PERMISSION_DENIED` 与 `FS_IO_ERROR` 区分已存在但并非目录的目标、被拒绝的列表操作和意外的后端 I/O 失败。`FS_SANDBOX_DENIED` 是强制执行沙箱的后端（`dsh-fs-sandbox`）所作的策略拒绝——模式边界拒绝了写入/编辑——与 `FS_PERMISSION_DENIED`（宿主内核拒绝）不同。`FS_NOT_OBSERVED` 表示策略插件没有此所有者的先前观察记录（或 `createIfAbsent` 遇到了现有文件）。`FS_STALE_VERSION` 表示后端版本不再与观察到的版本匹配（或编辑操作遇到缺失目标）。新鲜度授权没有部分/完整之分，因此不存在 `FS_PARTIAL_OBSERVATION`。
+
+## 服务与插件
+
+`FileSystem`（`ctx.fs`，abstract）拥有提供方原语：`resolve`、`stat`、`lstat`、`readText`、`streamText`、`listDir`、`writeText` 与 `editText`。`dsh-fs-policy` **不注册服务**——它是一个通过 `fs/*` 事件门禁添加策略的插件：对写入/编辑意图 waterfall 作出决策（提供 `createIfAbsent`/`replaceIfVersion`/`{ version }`，或抛出 `FS_NOT_OBSERVED`），并在 `fs/observed` 上记录。执行器是 `dsh-tool-fs`：它通过 `ctx.fs` 读取/写入/编辑，分发 waterfall，并 emit 记录事件。生成的 wiring 目录在 [services.md](../cordis-catalog/services.md#ctxfs--filesystem-abstract-seam) 中展示确切的 `ctx.fs` 签名。

# LLM Streaming
+English | [中文](llm-streaming.zh.md)

The wire-level streaming vocabulary of [dsh-llm](../../packages/llm/llm). [core.md](core.md) introduces `StreamChunk`, `Message`, and `ContentBlock`; this page owns the full chunk protocol, the adapter contract every adapter must obey, and the shared assembler.
Source: [`packages/llm/llm/src/types.ts`](../../packages/llm/llm/src/types.ts)
@@ -61,6 +63,7 @@ Every adapter MUST obey these, and every consumer may rely on them:
- **One adapter call is one provider attempt.** Adapters disable library retries. Agent-level recovery opens another durable numbered step; direct `ctx.llm.stream()` callers remain single-attempt.
- **Provider stalls are bounded at the transport.** Both shipping remote adapters expose positive finite `streamIdleTimeoutMs` with a five-minute default. The watchdog arms only while iterator `next()` is outstanding, uses one stable signal for the whole request, maps its own expiry to `TIMEOUT`, and keeps an earlier caller abort as `ABORTED`.
- **Context overflow has one canonical code.** Both DeepSeek adapters classify explicit provider detail through `isContextWindowExceededError()` and surface `CONTEXT_WINDOW_EXCEEDED`, whether the failure arrives as a thrown HTTP `LlmError` or an in-band finish error. Consumers route on the code, never provider text.
+- **An empty completion is a retryable error, not a silent success.** Both adapters map a terminal `stop` finish that carried no content blocks to `finish {kind:'error'}` with the canonical `EMPTY_RESPONSE` code, and `dsh-llm-retry` retries it by default; see [empty model responses are retryable](../../.agents/notes/implemented/bug-fix/2026-07-24-empty-model-response-is-retryable.md).
- **Every provider HTTP request carries the app-attribution header.** Adapters send `attributionHeaders()` (below) - the `User-Agent` baseline - and prove it with a wire-level test (mock server asserting the received header, or the library's header hook for a library-backed adapter).
- **Replay state is adapter-owned.** A successful `finish` may carry lossless-JSON state needed to reconstruct a native provider response. The loop stores it with the assembled assistant message unless an `agent/step-result` listener rewrote the content. On a later request, `LlmService` passes the state only when the historical provider and target provider are currently registered to the exact same adapter instance. That adapter validates the state and owns any cross-model or cross-provider conversion; other adapters receive the provider-neutral content and provenance without the private state.

+# LLM（大语言模型）流式输出
+
+[English](llm-streaming.md) | 中文
+
+[dsh-llm](../../packages/llm/llm) 的协议格式（wire format）级流式输出词汇。[core.md](core.md) 介绍了 `StreamChunk`、`Message` 与 `ContentBlock`；本页拥有完整的分片协议、每个适配器必须遵守的适配器契约（adapter contract），以及共享的 assembler。
+
+源码：[`packages/llm/llm/src/types.ts`](../../packages/llm/llm/src/types.ts)
+
+## `StreamChunk`：原始协议
+
+一个流式响应交错包含多种类型的块（文本、推理（reasoning）、多个工具调用）。`index` 将每个 delta 关联到其所属块；`block-end` 携带完整组装好的 `ContentBlock`，消费方无需自行重新组装 delta。这是一个**封闭的**可辨识联合类型：对 `type` 的 `switch` 以 `assertNever` 结尾，因此新增变体会在每个必须处理它的消费方处触发编译错误。
+
+```ts type-equiv
+/**
+ * Raw streaming protocol emitted by adapters.
+ * Block indexes correlate interleaved deltas, and `block-end` carries the
+ * assembled block. Adapters emit usage before the terminal finish and nothing
+ * afterward; tool arguments remain raw JSON strings. Failures either throw or
+ * end with `error`/`aborted`, and consumers must handle both paths.
+ */
+type StreamChunk =
+ | { type: 'block-start'; index: number; blockType: ContentBlockType }
+ | { type: 'text-delta'; index: number; text: string }
+ | { type: 'reasoning-delta'; index: number; text: string }
+ | { type: 'tool-call-delta'; index: number; id: CallId; name?: string; argumentsDelta: string }
+ | { type: 'block-end'; index: number; block: ContentBlock }
+ | { type: 'usage'; usage: TokenUsage }
+ | {
+ type: 'finish'
+ reason: FinishReason
+ /** Adapter-private lossless-JSON state for replaying a successful response. */
+ replayState?: unknown
+ }
+```
+
+## `LlmFailure`
+
+每个抛出的失败或最终适配器的带内失败都会规范化为一种可序列化、提供方无关的 payload。`providerRetryAfterMs` 是经校验、由提供方请求的正数延迟，而不是重试决策；`ProviderRequestId` 是用于诊断的不透明品牌字符串。
+
+```ts type-equiv
+/** Serializable provider-boundary facts; policy decides whether they are retryable. */
+interface LlmFailure {
+ /** Human-readable provider or transport failure. */
+ readonly message: string
+ /** Stable provider-neutral machine-routing code. */
+ readonly code: string
+ /** HTTP status observed at the provider boundary, when available. */
+ readonly status?: number
+ /** Provider-requested delay in milliseconds, when valid and available. */
+ readonly providerRetryAfterMs?: number
+ /** Opaque provider-issued request identifier for diagnostics. */
+ readonly requestId?: ProviderRequestId
+}
+```
+
+## 适配器契约
+
+每个适配器必须遵守以下规则，每个消费方可以依赖它们：
+
+- **`usage` 在 `finish` 之前，`finish` 之后不再有任何分片。** 将两者都推迟到提供方的流结束标记，这样尾部的 usage-only 分片就不会违反顺序。
+- **工具调用的 `arguments` 全程保持原始 JSON 字符串。** 部分片段通过 `argumentsDelta` 流式传输；如果提供方返回的是已解析的对象，适配器在 `block-end` 时重新序列化为字符串。
+- **两条受支持的错误路径，一种事实形状。** 失败可以从 `stream()` 抛出（传输/协议错误），**或者**以 `finish {kind:'error'|'aborted', failure}` 结束流（无法在流中途抛异常的适配器用它表示提供方带内错误）。`LlmError.failure` 携带同一个 `LlmFailure`。最终适配器边界保留被抛出的确切 `Error` 对象，并将不可变事实关联到该调用；agent loop（智能体循环）关闭失败的步骤，再把错误、事实与不可变的先前已重试事实提供给 `agent/request-error`。若未恢复，结构化失败会成为轮次错误，并且该次尝试不会提交正常 assistant 消息或工具副作用。
+- **一次适配器调用就是一次提供方尝试。** 适配器禁用库重试。agent 层恢复会打开另一个持久、带编号的步骤；直接调用 `ctx.llm.stream()` 的调用方仍然只尝试一次。
+- **提供方停顿在传输层受到时限约束。** 两个已交付的远程适配器都暴露正数且有限的 `streamIdleTimeoutMs`，默认五分钟。watchdog 只在 iterator `next()` 尚未完成时启动，整个请求使用同一个稳定 signal，把自身到期映射为 `TIMEOUT`，并把更早发生的调用方中止保留为 `ABORTED`。
+- **上下文溢出只有一个规范 code。** 两个 DeepSeek 适配器都通过 `isContextWindowExceededError()` 对提供方的显式细节分类并暴露 `CONTEXT_WINDOW_EXCEEDED`，无论失败以抛出的 HTTP `LlmError` 还是带内 finish error 到达。消费方按 code 路由，绝不依赖提供方文本。
+- **空 completion 是可重试错误，而不是静默的成功结果。** 两个适配器都把没有携带任何内容块的终止性 `stop` 结束映射为携带规范 `EMPTY_RESPONSE` code 的 `finish {kind:'error'}`，`dsh-llm-retry` 默认会重试它；详见[空模型响应可重试](../../.agents/notes/implemented/bug-fix/2026-07-24-empty-model-response-is-retryable.md)。
+- **每个提供方 HTTP 请求都携带应用归属头。** 适配器发送 `attributionHeaders()`（见下文）作为 `User-Agent` 基线，并通过协议级测试加以证明（mock 服务器断言收到的 header，或对基于库的适配器使用库的 header 钩子）。
+- **回放状态归适配器所有。** 成功的 `finish` 可以携带重建提供方原生响应所需的无损 JSON 状态。除非 `agent/step-result` listener 改写了内容，否则循环会将其与组装后的 assistant 消息一起存储。后续请求中，仅当历史提供方与目标提供方当前注册到完全相同的适配器实例时，`LlmService` 才会传递该状态。该适配器负责校验状态并拥有所有跨模型或跨提供方转换；其他适配器只会收到提供方无关的内容与 provenance，不会收到私有状态。
+
+该契约由两个有意保持独立的实现锁定：`dsh-llm-deepseek`（手写 fetch/SSE（Server-Sent Events））和 `dsh-llm-pi-ai`（通过 `@earendil-works/pi-ai` 实现的通用多提供方适配器）。基于库的适配器覆盖 finish 分片错误路径，而传输边界测试证明每个空闲 watchdog 都会停止其实际请求。
+
+## `AppIdentity`：应用归属
+
+每个适配器都会向提供方发送的静态公开应用标识（[`packages/llm/llm/src/attribution.ts`](../../packages/llm/llm/src/attribution.ts)）。`attributionHeaders(identity?)` 只把它映射到标准 `User-Agent` header；该契约有意不支持 OpenRouter 特有的应用归属 header。默认 `APP_IDENTITY` 从包（package） manifest（元数据清单）获取版本；每个字段都是公开产品事实——不含 secret、路径、会话 id 或逐用户标识，且任何逐请求信息都不得影响这些值。设计理由见[强制 `User-Agent` 归属](../../.agents/notes/implemented/architecture/2026-06-21-mandatory-app-attribution-headers.md)。
+
+```ts type-equiv
+/**
+ * Static public application identity sent to LLM providers.
+ *
+ * Every field is a public product fact, safe on every request: no secrets,
+ * local paths, session ids, prompt text, or per-user identifiers belong here,
+ * and nothing per-request may influence the values.
+ */
+interface AppIdentity {
+ /** `User-Agent` product token (lowercase, hyphenated). */
+ product: string
+ /** Product version; sourced from package metadata, never hand-copied. */
+ version: string
+ /** Public home URL of the app, used as the `User-Agent` comment. */
+ url: string
+}
+```
+
+## `TokenUsage`
+
+逐调用 token 记账。各计数**互不重叠**：`inputTokens` 只包含未缓存输入；缓存输入单独报告，计费输入是三者之和。若提供方把缓存命中折入单一提示词总数（如 DeepSeek 的 `prompt_tokens`），适配器会再将其扣除。`reasoningTokens` 存在时只是信息性细节，已经包含在 `outputTokens` 中；汇总时不得重复相加。
+
+```ts type-equiv
+/**
+ * Token accounting for one model call (cache fields are optional).
+ *
+ * Counts are DISJOINT: `inputTokens` is uncached input only; cached input is
+ * reported separately as `cacheReadTokens`/`cacheWriteTokens` (billed input =
+ * sum of the three). Adapters whose providers fold cache hits into a total
+ * prompt count (DeepSeek's `prompt_tokens`) subtract them out.
+ */
+interface TokenUsage {
+ inputTokens: number
+ outputTokens: number
+ cacheReadTokens?: number
+ cacheWriteTokens?: number
+ reasoningTokens?: number
+}
+```
+
+## `BlockAssembler`
+
+`BlockAssembler`（[`packages/llm/llm/src/assembler.ts`](../../packages/llm/llm/src/assembler.ts)）是唯一的共享实现，负责把 `StreamChunk` 流折叠回 `ContentBlock`、usage、结束原因与回放状态。循环在记录原始分片的同时，把同一批分片送入 assembler，再将组装后的 assistant 内容连同其提供方/模型 provenance 一起存储。需要组装结果、又不想重新实现 fold 的消费方使用它。
+
+```ts public-api
+/**
+ * Incrementally assembles raw {@link StreamChunk}s into complete
+ * {@link ContentBlock}s and a final assistant {@link Message}.
+ *
+ * The agent loop feeds it while logging raw chunks for replay fidelity, then
+ * reads `blocks()` / `message()` / `usage` / `finish` once the stream ends.
+ *
+ * Tolerant of delta-only protocols (no block-start/end); deltas arriving for
+ * an index already closed by `block-end` are ignored (malformed stream) so a
+ * misbehaving adapter cannot grow memory or corrupt a completed block.
+ */
+declare class BlockAssembler {
+ /**
+ * Feed one chunk into the assembly state.
+ * @param chunk - the next raw chunk, in stream order.
+ */
+ push(chunk: StreamChunk): void;
+ /**
+ * Assemble all blocks seen so far, in stream order.
+ * @returns one block per seen index; an open block assembles from its
+ * accumulated deltas (an unknown block type never closed by `block-end` throws).
+ */
+ blocks(): ContentBlock[];
+ /** Usage from the `usage` chunk; undefined until one arrives. */
+ get usage(): TokenUsage | undefined;
+ /** Finish reason from the `finish` chunk; `{kind: 'stop'}` when the stream ended without one. */

+`LlmAdapter` 是提供方 seam：创建子类、实现 `stream()`，再用 `ctx.llm.registerAdapter(providers, adapter)` 注册一个适配器实例。`GenerateOptions.provider` 选择已注册适配器；`GenerateOptions.model` 会传给该适配器，无需在生命周期启动时注册。重复提供方路由会原子失败。可选的 `providerInfo()` 与异步 `listModels()` 方法为 `LlmService.listProviders()` / `listModels()` 提供分离的 selector 元数据。该目录仅供参考，不是请求白名单：适配器仍是权威，并可接受未列出的模型 id。单独的 `resolveModelContext()` 查询会暴露确切路由上对正确性敏感的容量信息，但不会让目录成员关系具有权威性；缺失表示元数据未知，而不是路由无效。适配器查找发生在 `llm/stream` waterfall（瀑布式事件）的终端 continuation，因此 listener 可以在查找前短路调用，或路由一个可变的一次性请求。`block-start` / `block-end` 的 `index` 关联与 assembler 共同意味着适配器只需 emit 格式正确的分片——块重组不是每个适配器各自的问题。消费方 surface（`ctx.llm.stream()`）与 `llm/stream` waterfall 见 [architecture.md § 内容块与流式传输](../architecture.md#content-blocks-and-streaming-dsh-llm)。

# Session Persistence
+English | [中文](persistence.zh.md)
+
The **durability seam** for the event log. [session.md](session.md) describes the in-memory `Session` — the append-only `SessionEvent` log that is the source of truth. This page describes how that log is made durable: the abstract `SessionPersistence` service, its backends, the flush checkpoint, crash recovery, and the metadata header that travels alongside the log. The event vocabulary the log carries is enumerated, member by member, in the generated [persistence log event catalog](../persistence-catalog.md).
The seam is a textbook [capability seam](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md): one abstract service ([dsh-session-persistence](../../packages/session-persistence/session-persistence), `ctx.sessionPersistence`) defining locate/create/append, crash-repairing load, non-mutating inspect, and lightweight list/snapshot observation over the existing `SessionEvent` — **no parallel persisted type** — and two interchangeable backends that pass the same `runPersistenceContract` suite. See the [session-persistence Agent Note](../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.md).

+# 会话持久化
+
+[English](persistence.md) | 中文
+
+事件日志的**持久性 seam**。[session.md](session.md) 描述了内存中的 `Session`：仅追加的 `SessionEvent` 日志即为真源。本页描述如何使该日志持久化：抽象的 `SessionPersistence` 服务、它的后端、flush 检查点、崩溃恢复，以及随日志一同存储的元数据头。日志承载的事件词汇在生成的[持久化日志事件目录](../persistence-catalog.md)中逐项列举。
+
+该 seam 是典型的[能力 seam](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)：一个抽象服务（[dsh-session-persistence](../../packages/session-persistence/session-persistence)，`ctx.sessionPersistence`）在现有 `SessionEvent` 上定义 locate/create/append、会执行崩溃修复的 load、不会修改数据的 inspect，以及轻量的 list/snapshot 观察——**没有平行的持久化类型**——以及两个可互换、通过同一套 `runPersistenceContract` 的后端。见 [session-persistence Agent Note（agent 决策记录）](../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.md)。
+
+## flush 检查点
+
+`session/event` 是一个*同步*通知；持久化插件会将事件复制到逐会话控制器，并立即启动写入而不阻塞生产方。并发事件会加入当前批次；在该批次写入期间接纳的事件会触发后续批次。`session/flush` 会等待当前与待处理批次全部清空，因此循环仍将其用作在领取下一个普通轮次之前的顺序与错误观察检查点。立即写入被拒绝时会保留对应事件；显式 flush 会重试这些事件，并通过 `agent/error` 和 logger 报告失败，绝不会把失败记录成已关闭轮次之后的会话事件。dispose（资源释放）会执行同样的最终排空。
+
+## 崩溃恢复保留被中断的轮次
+
+后端重新加载一个在轮次中途崩溃的日志时，会发现一个已打开的 `turn/start` 却没有 `turn/end`。它**不会**截断日志：在长周期任务中，单个轮次可能非常庞大（许多步骤、大量工具输出），而这些事件在崩溃前已被持久追加。后端改为用一个合成的 `turn/end { reason: { kind: 'interrupted' } }` 关闭这个遗留轮次，保持日志平衡与轮次闭合不变式。`interrupted` 是唯一一个不由循环发出的 `TurnEndReason`（见 [session.md](session.md#why-a-turn-ended-turnendreasonmap)）。
+
+修复仅适用于冷会话。对于活跃 id，`SessionPersistence.load(id)` 会对内存日志拍摄快照，等待该快照完成持久化，并且只在日志平衡时连同已存储的 header 返回；若活跃轮次仍未闭合，则拒绝操作，而不是添加合成的中断边界。由协调器管理的冷加载会在后端读取和修复写入期间占用该 id，因此并发发布同 id 的活跃会话会被拒绝并回滚。HMR 也会接管活跃前缀，而不会关闭其中正在进行的轮次。
+
+`SessionPersistence.inspect(id)` 是恢复机制面向观察方的对等操作：它返回已存储有效前缀的独立副本，不截断不完整记录、不添加中断结束事件，也不发布写入状态。同 id 串行化确保它与后端写入保持一致。派生读取模型使用 `inspect`，绝不使用 `load`，因此即使活跃所有权并发建立，观察已落检查点但仍未闭合的轮次也不会修改日志。
+
+## `SessionLocation`——可选的逐会话产物目标
+
+`SessionPersistence.locate(meta)` 会同步解析一个归后端所有的独立产物，而不会读取、创建或 flush 它。JSONL 返回其项目/会话目录内 transcript（文本记录）的绝对路径；SQLite 因各会话共享一个数据库而返回 `undefined`。因此，返回的路径可能指向尚不存在、或还不包含当前尚未 flush 的轮次；它是位置提示，不是授权或新鲜度保证。
+
+```ts type-equiv
+/**
+ * A backend-resolved, per-session local artifact location. The path is an
+ * absolute target path and can name an artifact that has not materialized yet.
+ * Consumers must treat it as a location hint, never as an authorization token.
+ */
+interface SessionLocation {
+ /** Backend-specific artifact kind, for example `jsonl`. */
+ readonly kind: string
+ /** Absolute path to this session's backend-owned artifact. */
+ readonly path: string
+}
+```
+
+## `SessionHeader`：日志旁的元数据
+
+每个会话的元数据与事件日志**分开**存储：格式版本、cwd、血统与 seed 边界是存储层关注点而非对话事件，因此不进入 `SessionEventMap`，也不会到达 `deriveMessages()`。header 通过 `session.header` 附加到 `Session` 上。
+
+源码：[`packages/core/session/src/types.ts`](../../packages/core/session/src/types.ts)
+
+```ts type-equiv
+/**
+ * Immutable validated storage metadata, kept outside the conversation event log.
+ */
+interface SessionHeader {
+ /**
+ * On-disk format version, stamped from {@link SESSION_FORMAT_VERSION} when the
+ * session is created. A persistence backend rejects any other version on load
+ * (no migration — see the constant).
+ */
+ readonly version: number
+ /** The session's id (mirrors the {@link Session}'s id). */
+ readonly id: SessionId
+ /** Non-negative safe-integer Unix epoch milliseconds when the session was created. */
+ readonly createdAt: number
+ /** Absolute working directory the session was created in (if any). */
+ readonly cwd?: string
+ /** The session this one was forked from (seed lineage), if any. */
+ readonly parentSession?: SessionId
+ /**
+ * How many leading events were inherited through a seed. Persisting this
+ * boundary lets resume and replay distinguish parent history from child work.
+ */
+ readonly seedLength?: number
+ /**
+ * Delegation depth: absent (zero) for a top-level session, parent depth + 1
+ * for a subagent child. Persisted so a recursion budget survives restart and
+ * resume — a runtime-only depth would reset a resumed child to top-level.
+ */
+ readonly delegationDepth?: number
+}
+```
+
+## `CreateSessionOptions`：seed 与元数据
+
+通过 store 创建 `Session` 时会接收 `seed`（回放/fork 现有事件日志）与 `meta`（store 折叠进 `SessionHeader` 的存储层字段）。store 填充 `version`/`id` 并为 `createdAt` 提供默认值；调用方提供已校验的绝对 `cwd`、`parentSession` 谱系、`seedLength` 种子边界、`delegationDepth`，以及——仅在重建已持久化会话时——需要保留的原始 `createdAt`。
+
+```ts type-equiv
+/**
+ * Options for creating a {@link Session} via the store. `seed` replays/forks
+ * an existing event log; `meta` carries the caller-supplied storage fields the
+ * store folds into a {@link SessionHeader}.
+ */
+interface CreateSessionOptions {
+ /** Events to seed the new session with (replay/fork). */
+ readonly seed?: readonly SessionEvent[]
+ /**
+ * Storage metadata read once before publication. `seedLength` is explicit
+ * because a resumed seed contains the full stored log, not only its inherited prefix.
+ */
+ readonly meta?: {
+ readonly cwd?: string
+ readonly parentSession?: SessionId
+ readonly createdAt?: number
+ readonly seedLength?: number
+ readonly delegationDepth?: number
+ }
+}
+```
+
+因此，回放/fork 的调用方式为 `ctx.sessions.create(id, { seed: seedEvents })`；将一个*持久化*会话恢复为活跃 agent 的调用方式为 `ctx.agents.resume({ resumeSessionId })`。
+
+## 轻量源修订号
+
+派生状态的消费方会在加载完整事件日志之前比较一个低开销的不透明修订号。其表示由持久化后端拥有，并随 append 或会修改数据的 load 修复以事务方式改变；调用方仅比较修订号是否相等。
+
+```ts type-equiv
+/**
+ * Backend-owned token that identifies both one storage source and one revision
+ * of a persisted session log.
+ */
+type SessionPersistenceRevision = Branded<'SessionPersistenceRevision'>
+```
+
+```ts type-equiv
+/** Lightweight immutable source identity returned without loading a full log. */
+interface SessionPersistenceSnapshot {
+ /** Detached metadata for one materialized session. */
+ header: SessionHeader
+ /** Opaque source-qualified token that changes whenever this stored log changes. */
+ revision: SessionPersistenceRevision
+}
+```
+
+## 后端
+
+两者都实现同一个抽象 `SessionPersistence`（在 `SessionEvent` 上执行 locate/create/append/load/inspect/list/listSnapshots），并通过 `runPersistenceContract`，证明该 seam 确实与后端无关：
+
+- **[dsh-session-persistence-jsonl](../../packages/session-persistence/session-persistence-jsonl)**——每个会话一份仅追加的逻辑 JSONL 日志，默认存储为带 checksum 的连续 Zstandard frame，也可配置为原始行；支持崩溃安全的原子写入、被中断轮次的恢复以及读取/回放路径。
+- **[dsh-session-persistence-sqlite](../../packages/session-persistence/session-persistence-sqlite)**：基于 `node:sqlite`，每个 `SessionEvent` 一行。行结构 `(session_id, seq, type, time, data, source_event_seqs, surface_op)` 与事件 1:1 映射（包含可选的 surface 元数据），因此没有需要保持同步的并行持久化 schema。

# Process Sandbox

The process-sandbox seam of [dsh-sandbox](../../packages/sandbox/sandbox) wraps a same-world subprocess argv in a file-effect policy without coupling consumers to a platform runner. [dsh-sandbox-local](../../packages/sandbox/sandbox-local) supplies the Linux bwrap/Landlock and macOS Seatbelt backends; [dsh-bash-sandbox](../../packages/bash/bash-sandbox) is the first consumer.

+# 进程沙箱
+
+[English](sandbox.md) | 中文
+
+[dsh-sandbox](../../packages/sandbox/sandbox) 的进程沙箱 seam 将与宿主共享文件系统和内核的子进程 argv 包装在文件效果策略中，而不将消费方耦合到特定平台运行器。[dsh-sandbox-local](../../packages/sandbox/sandbox-local) 提供 Linux bwrap/Landlock 与 macOS Seatbelt 后端；[dsh-bash-sandbox](../../packages/bash/bash-sandbox) 是第一个消费方。容器、microVM 和远程执行是完整能力 seam 的兄弟实现，而非 `ctx.sandbox` 的提供方。
+
+源码：[`packages/sandbox/sandbox/src/index.ts`](../../packages/sandbox/sandbox/src/index.ts)
+
+## 模式与强制执行
+
+`SandboxMode` 仅管控文件系统效果。`read-only` 拒绝所有写入（必需的 `/dev/null` 接收器除外）；`workspace-write` 允许在工作区根目录及后端承诺的临时区域下写入；`danger-full-access` 绕过隔离。网络与进程可见性不在此处的定义范围内。
+
+```ts type-equiv
+/**
+ * File-effect policy for confined processes. `read-only` permits only required
+ * sinks such as `/dev/null`; `workspace-write` also permits the workspace and a
+ * backend-defined temp area; `danger-full-access` bypasses confinement. Network
+ * and process visibility are outside this vocabulary.
+ */
+type SandboxMode = 'read-only' | 'workspace-write' | 'danger-full-access'
+```
+
+只有前两种模式可以发送给提供方。`danger-full-access` 的消费方直接 spawn 原始 argv，不调用 `ctx.sandbox`。
+
+```ts type-equiv
+/** A confining (non-`danger-full-access`) mode — the modes a {@link SandboxPolicy} can carry. */
+type ConfinedSandboxMode = Exclude<SandboxMode, 'danger-full-access'>
+```
+
+强制执行程度是一个报告事实。`full` 表示后端管控了该模式承诺的所有文件效果；`partial` 表示活跃后端或较旧的内核 ABI 仅管控其中一个子集，因此要求绝对保证的消费方必须拒绝或向上暴露这一区别。
+
+```ts type-equiv
+/**
+ * Enforcement completeness for this host. `partial` means an active backend or
+ * older kernel ABI cannot govern every promised file effect; callers requiring
+ * an absolute boundary must not treat it as `full`.
+ */
+type SandboxEnforcement = 'full' | 'partial'
+```
+
+## 逐调用策略
+
+完整执行策略会按每次能力调用解析并携带。它包括 `danger-full-access`，因此消费方可以只解析一次策略，再决定是否绕过约束。普通工具调用从调用会话的不可变 cwd 派生 `workspaceRoot`；部署配置是没有 agent（智能体）时的回退值。root 会先按文件系统语义规范化，再做词法规范化，因此包含 `symlink/..` 的 cwd 会标识所生成进程实际运行的目录。
+
+```ts type-equiv
+/**
+ * The complete file-effect policy resolved for one capability call. The root
+ * is carried even under modes that do not consume it so callers can resolve
+ * policy once before choosing the enforcement path.
+ */
+interface SandboxExecutionPolicy {
+ /** The file-effect mode this execution runs under. */
+ mode: SandboxMode
+ /** Absolute root directory `workspace-write` may write under. */
+ workspaceRoot: string
+}
+```
+
+`ctx.sandboxPolicy.resolve()` 接收活跃会话；对于已批准的重试，还接收显式模式。该服务拥有优先级与 root 回退规则，使 bash 和 fs 不必重复实现。
+
+```ts type-equiv
+/** Inputs that select the sandbox policy for one capability call. */
+interface SandboxPolicyRequest {
+ /** Calling session; its immutable cwd becomes the workspace boundary. */
+ session?: Session
+ /** Explicit approved mode override, which outranks session policy. */
+ mode?: SandboxMode
+}
+```
+
+只有受约束的执行会到达 `ctx.sandbox`；其提供方策略在保留同一 root 的同时收窄模式。这使并发会话、消费方与一次性提权重试可以向同一提供方请求不同边界，而无需改变提供方状态。
+
+```ts type-equiv
+/**
+ * What one confined execution is allowed to touch — carried PER CALL, not
+ * fixed on the provider: two consumers may confine under different policies
+ * at the same instant (bash under `read-only` while a confined child agent
+ * needs its state directory writable), and an approved escalated retry is a
+ * new call with a wider policy. Defaulting/resolution is an explicit step at
+ * the consumer boundary; the provider treats the policy as fully specified.
+ */
+interface SandboxPolicy extends SandboxExecutionPolicy {
+ /** The file-effect mode this execution runs under. */
+ mode: ConfinedSandboxMode
+}
+```
+
+## 包装后的 argv 与分类方言
+
+`ConfinedArgv` 是消费方实际 spawn 的内容。除了替换后的 argv，它还携带后端的强制执行事实和两种正交的 stderr 方言。`denialSignatures` 用于识别沙箱正常工作时被隔离命令被阻止的情况。`runnerFailureSignatures` 用于识别沙箱运行器在执行命令之前拒绝或失败的情况；消费方应先检查后者，将其作为沙箱基础设施故障上报，而非普通任务失败。
+
+```ts type-equiv
+/**
+ * A {@link SandboxProvider.confine} result: the argv to spawn in place of
+ * the caller's own, plus the enforcement completeness the selected backend
+ * achieves for it.
+ */
+interface ConfinedArgv {
+ /** The wrapped argv (runner, profile, separator, then the caller's argv). */
+ argv: string[]
+ /** How completely the selected backend enforces the policy's file effects. */
+ enforcement: SandboxEnforcement
+ /**
+ * The selected backend's denial DIALECT: the case-insensitive stderr
+ * substrings a file effect denied by THIS backend produces (EROFS text
+ * under bwrap's read-only binds, EACCES under Landlock, EPERM under
+ * Seatbelt). A consumer that infers denials from a failed run's stderr
+ * matches against exactly these rather than a cross-backend union — the
+ * union claims denials a given backend never produces.
+ */
+ denialSignatures: readonly string[]
+ /**
+ * Case-insensitive signatures for runner failure before command execution.
+ * Consumers check these before denial signatures: runner failure means the
+ * command never ran, while denial means confinement worked and blocked it.
+ */
+ runnerFailureSignatures: readonly string[]
+}
+```
+
+运维人员配置的本地运行器必须为自身的 pre-exec 拒绝方言提供至少一条 `runnerFailureSignatures` 条目；提供方会自动添加外层 shell 的 missing 和 unexecutable 形式。这使得可执行的自定义运行器拒绝其 profile 的情况能够与被包装命令以相同状态码退出的情况区分开来。
+
+## 提供方与 fail-closed 错误
+
+`ctx.sandbox.confine(argv, policy)` 返回一个 `ConfinedArgv`，或在没有可用后端时抛出 `SandboxUnavailableError`（错误码 `SANDBOX_UNAVAILABLE`）。已选定的运行器也可能在执行时 fail-closed，此时其失败签名承载相同的基础设施含义。对于受限策略，静默的无隔离透传永远不合法。
+
+提供方探测在多个候选后端之间仲裁，结果在提供方生命周期内缓存。只有一个候选后端的平台可以直接选定它；执行时拒绝仍保留安全属性。本地提供方将 bwrap 和 Seatbelt 报告为 full，并保留 Landlock 启动器的 full/partial 内核裁定。

# Scoped Registration

The [scope package](../../packages/core/scope) supplies the identity, carrier, and scoped-layer vocabulary that makes one registration context mean both per-agent visibility and shared lifetime ownership. It is a library primitive rather than a Cordis service; the [agent-scope runtime-design Agent Note](../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.md#scope-routing-one-opaque-key-selects-one-layer) owns the lifecycle rationale, the [shared-storage Agent Note](../../.agents/notes/implemented/architecture/2026-07-12-scoped-layers-store.md) owns the registry-layer decision, and the package [README](../../packages/core/scope/README.md) owns the callable API and filtering semantics.

+# 作用域注册
+
+[English](scope.md) | 中文
+
+[scope 包（package）](../../packages/core/scope)提供 identity、carrier 与 scoped-layer 词汇，使同一个注册上下文同时代表逐 agent（智能体）可见性和共享生命周期所有权。它是库原语，而不是 Cordis 服务；生命周期设计理由由 [agent-scope 运行时设计 Agent Note（agent 决策记录）](../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.md#scope-routing-one-opaque-key-selects-one-layer)规定，注册表层决策由[共享存储 Agent Note](../../.agents/notes/implemented/architecture/2026-07-12-scoped-layers-store.md)规定，可调用 API 与过滤语义则由包 [README](../../packages/core/scope/README.md)规定。
+
+源码：[`packages/core/scope/src/index.ts`](../../packages/core/scope/src/index.ts) 与 [`packages/core/scope/src/store.ts`](../../packages/core/scope/src/store.ts)。
+
+## 身份标识与分发载体
+
+`ScopeKey` 是一个不透明的对象身份标识。已交付的 agent loop（智能体循环）使用活跃的 `Agent` 对象作为自身的 key，但该原语从不检视该对象。
+
+```ts type-equiv
+/** An opaque, identity-compared scope key. */
+type ScopeKey = object
+```
+
+`Scoped<T>` 是编译期品牌标记，标注在 `scopeTarget(base, key)` 返回的不透明路由接收器上。作用域过滤的事件声明要求以此载体作为 `this` 类型，而真正的事件主体仍作为显式参数传入。
+
+```ts type-equiv
+/**
+ * A routing-only event receiver built by {@link scopeTarget}. The type
+ * parameter records the subject type for dispatch checking; the carrier does
+ * not expose the subject's properties. Event payloads carry the real subject.
+ */
+type Scoped<T extends object> = object & { readonly [ScopedBrand]: T }
+```
+
+## 拥有所有权的注册上下文
+
+`Scope` 将带标签的注册上下文与两个拆卸接口配对。`rawDispose` 保留有序复合 effect 所需的精确 Cordis disposer 身份；`dispose()` 是面向直接调用方和竞态调用方的公共停稳边界。
+
+```ts type-equiv
+/** A minted registration scope and its quiescent disposal boundaries. */
+interface Scope {
+ /** Context through which scope-owned registrations are made. */
+ ctx: Context
+ /** Exact Cordis disposer, used when nesting this scope in an ordered composite effect. */
+ rawDispose: () => Promise<void> | void
+ /** Dispose every scope-owned registration; racing calls await the same completion. */
+ dispose(): Promise<void>
+}
+```
+
+## 带作用域的注册表层
+
+`ScopeLayer` 表示一个注册表在全局或确切作用域层级的完整贡献。具体 layer 可以聚合多个具名与匿名 table；整个 layer 为空时，`ScopedLayers` 可以回收带作用域状态，而不会丢弃兄弟 table。
+
+```ts type-equiv
+/** One scope's aggregate contribution to a registry. */
+interface ScopeLayer {
+ /** Whether every table in this layer is empty. */
+ isEmpty(): boolean
+}
+```
+
+`ScopedLayers<L>` 拥有立即创建的全局 layer，以及惰性创建的确切作用域 layer。读取不会创建 layer：`peek(undefined)` 表示没有 overlay，而 `merge()` 会物化按插入顺序排列的全局具名 entry，随后是带作用域的 shadow。注册使用同一个上下文表示可见性与 Cordis effect 所有权，在可选通知前收集一个同步 undo，返回 Cordis 的确切 disposer，并且只在带作用域 layer 的完整 `ScopeLayer` 为空时回收它。
+
+`NamedEntries<V>` 提供按插入顺序的查找与 live iteration，重复错误由调用方所有。`AnonymousEntries<V>` 为每次 append 分配唯一标识，使相等的值仍相互独立。迭代在同一非空 table generation 内保持 live；排空 table 会让现有 iterator 与后续插入脱离。两者都返回幂等的确切 entry undo；共享的 `EntryValues` 实现接口不公开。

+本文定义面向优先使用 live 数据的逻辑会话语料库的查询词汇。[接口包（package）](../../packages/session-query/session-query)负责精确读取、来源优先级、关系追踪、语义提取，以及与提供方无关的过滤器；[SQLite 包](../../packages/session-query/session-query-sqlite)负责具体全文索引的生命周期。

+
+`SessionRecord` 由跨语料库列表返回。它独立于克隆后的实时优先 header 暴露源可用性。`SessionEventRecord` 是轻量的原始日志投影；分类使用与 model-history 推导相同的 `foldSurface()` 状态转换。
+
+```ts type-equiv
+/** Whether an event is current model context, replaced context, or raw-log-only. */
+type SessionEventSurface = 'current' | 'shadowed' | 'log-only'
+```
+
+```ts type-equiv

+ /** Whether the active persistence backend currently materializes the id. */
+ persisted: boolean

+
+`SessionLogSnapshot` 是供恢复预检使用的完整原始日志：它脱离运行时，并经过回放验证。`SessionSurfaceSnapshot` 表示一次精确读取的 surface 观测结果，而不是持续保留的订阅。
+
+```ts type-equiv
+/** One validated detached observation of a logical session's complete raw log. */

+interface SessionEventSearchDocument extends SessionEventRecord {
+ /** First-party semantic text used by scan filters and full-text indexes. */

+
+`ctx.sessionQuery.filterSessions(filters)` 会对完整的逻辑会话语料库应用 `SessionResultFilter`；`ctx.sessionQuery.filterEvents(sessionId, filters)` 按 seq 升序返回匹配的文档。消息、推理（reasoning）、工具调用和工具结果、被阻止的提示词、待办事项，以及失败和状态详情会纳入语义文本；结构事件和流分片则不会。

+

+```
+
+与跨会话分组 hit 不同，会话内搜索即使没有命中项，也必须公开它观测到的目标 header。
+
+```ts type-equiv

+ /** Strongest matching event for this session. */
+ bestMatch: SessionEventSearchHit
+}
+```
+
+## 会话谱系
+
+`SessionLineageTrace` 按由近及远的顺序携带已知 parent，并携带一片由直接 descendant 递归嵌套而成的森林。完整性判别字段使已知 root 与缺失 parent 互斥。
+
+```ts type-equiv

+ /** First parent id that is not present in the logical corpus. */
+ unresolvedParentId: SessionId
+ }
+)
+```
+
+## 有界事件读取
+
+请求指定一个原始 seq 及可选的邻近数量。结果携带 `SessionHeader` 而非可用性标志，使已知的实时目标可以独立于持久化健康状态。
+
+```ts type-equiv
+/** Request for one event plus raw neighboring log context. */

+ startSeq: number
+ /** Last seq included in `events`. */
+ endSeq: number

+
+## 事件关系
+
+事件追踪会区分位置性的 surface 替换与已记录 provenance。除 `replacementChain` 外，每个 seq 列表都包含直接链接；该链从目标沿直接 replacer 追踪到最终的位置替换。

The in-memory, event-sourced model of [dsh-session](../../packages/core/session). A `Session` is an **append-only log** of typed `SessionEvent`s — the single source of truth for an agent's whole interaction history. The LLM message history is *derived* from the log, never stored separately; replay is re-derivation from the same events. How the log is made **durable** (the persistence seam, backends, crash recovery) is the sibling concern on [persistence.md](persistence.md).

These are **log-only**: NOT `SurfaceEventType`s (they carry no `surfaceOp` and contribute nothing to derived history), but, like every event, they must sit inside an open turn. The full per-event enumeration — core and plugin-contributed alike, with payloads and provenance — is the generated [persistence log event catalog](../persistence-catalog.md); the compaction seam's `compact/*` semantics are discussed on [compaction.md](compaction.md).

+```ts type-equiv
+/**
+ * Surface placement and provenance for {@link Session.append}. Required on
+ * message-producing events and forbidden on log-only events.
+ */
+interface SurfaceIntent {
+ surfaceOp: SurfaceOp
+ /**
+ * Complete known provenance source set. `assistant/message` may use a
+ * present empty array for a known empty provider stream; omission means its
+ * provenance was not recorded. Other surface events require a non-empty set
+ * when this field is present.
+ */
+ sourceEventSeqs?: number[]
+}
+```
+
+对 `SurfaceEventType` 事件必填：每个产生消息的事件都必须声明它如何加入 surface（派生历史的唯一来源）。非 surface 类型在编译期拒绝此参数。
+
+此处适用相同的溯源区分：只有 `assistant/message` 可以携带存在但为空的 `sourceEventSeqs`；省略该字段并不表示其源流为空。
+
+### `SessionSurface`：实时只读 surface 投影
+
+`Session.surface` 返回会话稳定的 `SessionSurface` 视图。同一个增量管理器在提交前校验追加候选事件，并根据已提交事件推进该投影；调用方可以观察成员关系和替换代次，但不能调用校验。
+
+```ts type-equiv
+/** Readonly live projection of the message-producing session events. */
+interface SessionSurface {
+ /** Current surface event sequences in model-visible order. */
+ readonly nodes: readonly number[]
+ /** Monotonic count of committed positional replacements. */
+ readonly replaceGeneration: number
+}
+```
+
+### `SurfaceFoldReplacement` 与 `SurfaceFoldResult`：完整的 surface 回放
+
+`foldSurface(events)` 返回一份独立的当前事件 seq 列表，以及每个声明的替换范围实际遮蔽的 seq。实时管理器复用同一套状态转换，但不保留替换历史。每提交一次替换，其 `replaceGeneration` 就递增一次，使增量消费方能够区分纯尾部增长与重写。
+
+```ts type-equiv
+/** One replacement operation observed while folding a session surface. */
+interface SurfaceFoldReplacement {
+ /** Seq of the event that replaced the prior surface range. */
+ seq: number
+ /** Declared inclusive start seq of the replaced surface range. */
+ start: number
+ /** Declared inclusive end seq of the replaced surface range. */
+ end: number
+ /** Actual surface entries removed by the operation, in surface order. */
+ shadowedSeqs: number[]
+}
+```
+
+```ts type-equiv
+/** Complete result of replaying the surface operations in a session log. */
+interface SurfaceFoldResult {
+ /** Current surface event sequences in model-visible order. */
+ nodes: number[]
+ /** Replacement operations in event order. */
+ replacements: SurfaceFoldReplacement[]
+}
+```
+
+## `Session` public API
+
+去除方法体的声明与源码中的普通类保持同步，覆盖其公共构造函数、状态访问器、追加边界和历史投影。存储操作仍由生成的 [`ctx.sessions` 服务目录](../cordis-catalog/services.md#ctxsessions--sessionstore)记录。

+
+## 派生历史：`deriveMessages()` 与 `deriveEventMessage()`
+
+`Session.deriveMessages()` 将事件日志投影为模型看到的 `Message[]`。它是缓存的（每个 surface 节点在首次出现时投影一次；surface 重写触发重建）且冻结的（每次调用返回一个新数组，引用共享的深冻结消息，因此通过投影修改已记录的历史在类型上不可表达）。`deriveEventMessage(event)` 是折叠所应用的逐节点纯函数，公开暴露以便外部重建器和开发不变式检查能以完全相同的规则投影日志前缀，不会与缓存产生分歧。投影规则：
+
+- `user/message` → 一条携带确切 `content` 的 user 消息；可选 envelope 仅作为日志中的展示元数据保留。
+- `assistant/message` → 一条 assistant 消息，包含事件的提供方/模型溯源信息和可选的适配器私有回放状态。原始 `assistant/chunk` 事件属于回放/UI 数据，在派生时会被**跳过**（组装后的消息才是权威）。**内容为空的** `assistant/message` 也会跳过：因 max-tokens 而截断且无内容的步骤仍会记录一条 `assistant/message` 以承载用量和溯源信息，但无内容的 assistant 轮次不得进入提供方 transcript。
+- `tool/result` → 一条携带 `tool-result` 块的 user 消息。
+- `user/message`（注入上下文，即非 `user` 来源）→ 按时间顺序在相应位置生成一条 user-role 消息，并原样承载其 `content`。可选的 JSON `meta` 保留在事件日志中，绝不渲染。
+- `steering/message` → 按时间顺序在相应位置生成一条携带确切 `content` 的 user-role 消息；可选 envelope 仅作为日志中的展示元数据保留。
+
+其余所有事件（`turn/*`、`step/*`、插件所有的 `llm/retry`）均为结构信息，不会投影为消息。token 记账读取每个步骤的 `assistant/chunk { type: 'usage' }` 记录；如果没有用量分片，则将 `assistant/message.usage` 作为已提交步骤的后备。失败的模型请求尝试没有 assistant 消息，因此其用量分片是持久化的记账记录。操作错误的步骤号记录在 `turn/end.reason`（`kind: 'error'`）中；如果是最终模型请求失败，其中包含规范化的 `LlmFailure` 事实，其他实时错误则包含消息/代码。由于这一尚未发布的格式有意不提供兼容性承诺，seed/load 校验会拒绝缺少提供方和模型的请求头，以及缺少提供方/模型溯源信息的 assistant 消息，而不会猜测历史数据应走的提供方路由。
+
+## 活跃会话 fork API
+
+`ctx.sessions.create(id, { seed, meta })` 是底层的回放/fork 原语。对于普通的活跃会话 fork，`SessionStore` 暴露一个策略 API：
+
+- `fork(source, boundary?, childSessionId?)` 接受一个活跃的 `Session` 对象或活跃的 `SessionId`，选取到 `boundary` seq（含）为止的源事件（默认为当前最后一个事件），要求 boundary 事件必须是 `turn/end`，然后创建一个活跃的子会话，包含深克隆的种子事件和子会话元数据（`parentSession`、`seedLength` 及继承的 `cwd`）。
+
+显式 `boundary` 允许调用者从之前完成的轮次 fork，即使源会话有更新的事件或正在进行的轮次。API 拒绝非 `turn/end` 的 boundary，而不是静默截断。更广泛的轮次封闭性检查留在既有的 `dsh-invariants` 插件和持久化修复路径中，不在 `fork()` 中重复。`dsh-subagent-fork` 保留其已完成前缀截断逻辑，因为工具时委托通常在父轮次仍然打开时启动；普通的会话分支应显式指定请求的 boundary。
+
+## 轮次的触发原因：`TurnTriggerMap`
+
+```ts type-equiv
+/**
+ * What started a turn.
+ * Merge-extensible sum type (same pattern as MessageSourceMap).
+ */
+interface TurnTriggerMap {
+ message: { kind: 'message'; source: MessageSource }
+ /**
+ * An out-of-band context injection (`agent.inject()`) made while the agent
+ * was idle. The loop wraps the injected `user/message` (a non-`user` source,
+ * plugin by default) in a one-shot turn (`turn/start` → `user/message` →
+ * `turn/end`) so every event in the log stays turn-enclosed — the
+ * durability/replay boundary is the turn, and a bare event between turns would
+ * otherwise be indistinguishable from a crash tail on reload. The trigger's
+ * `source` mirrors that message's producer.
+ */
+ injection: { kind: 'injection'; source: MessageSource }
+}
+```
+
+<a id="why-a-turn-ended-turnendreasonmap"></a>
+
+## 轮次的结束原因：`TurnEndReasonMap`
+
+`aborted` 有意作为一种粗粒度的持久结果：它只记录取消中断了实时轮次，不记录是哪个运行时调用方发起取消。仅属于运行时的调用方词汇由 [`AgentCancelCause`](core.md#the-agent-handle) 定义；未来若有审计需求，应新增独立的控制请求事件，而非让终止结果承载这一信息。
+
+```ts type-equiv
+/**
+ * Why a turn ended. Merge-extensible sum type.
+ */
+interface TurnEndReasonMap {
+ completed: { kind: 'completed' }
+ /** A cancellation request interrupted the live turn. */
+ aborted: { kind: 'aborted' }
+ /**
+ * The turn failed: a step threw or the model reported a failure. `step` is the
+ * step number the failure occurred on (the operational error's location — the
+ * single durable record of an in-turn failure; live diagnostics also fire via
+ * `agent/error`). Final model-request failures retain their normalized facts
+ * as one `failure`; other turn failures retain their live Error message/code.
+ */
+ error: { kind: 'error'; step: number } & (
+ | { failure: LlmFailure; message?: never; code?: never }
+ | { message: string; code?: string; failure?: never }
+ )
+ disposed: { kind: 'disposed' }
+ /** At least one step reached its output-token ceiling, even if a plugin continued the turn. */
+ 'max-tokens': { kind: 'max-tokens' }
+ /**
+ * Policy blocked the turn's claimed prompt before the first step. The
+ * zero-step turn still records a balanced durable boundary and veto reason.
+ */
+ rejected: { kind: 'rejected'; reason: string }
+ /**
+ * A persistence backend closed a crash-orphaned turn on reload. The loop never
+ * emits this marker, and the events recorded before the crash remain intact.
+ */
+ interrupted: { kind: 'interrupted' }
+}
+```
+
+`max-tokens` 与模型调用中同名的 `FinishReason` 对应：只要轮次内有任何步骤以 `max-tokens` 结束，整个轮次就以 `max-tokens` 而不是 `completed` 结束（即使之后继续执行，截断事实仍优先），让消费方能够区分正常停止和截断停止；但它只优先于 `completed`，`disposed`/`aborted`/`error` 结果的优先级更高。`rejected` 表示一个零步骤轮次，其已认领的提示词被 `agent/prompt-submit` 钩子阻止（ACP（Agent Client Protocol）桥接层将其映射为 `cancelled`）。`interrupted` 是唯一不会由任何 loop 发出的原因：它由崩溃恢复合成（见 [persistence.md](persistence.md)）。两个 map 均可通过合并扩展。
+
+## 轮次封闭不变式
+
+每个会话事件都位于一个轮次**之内**（在 `turn/start` 和对应的 `turn/end` 之间）。loop 在 `turn/start` *之后*追加已排队的 `user/message` 事件；空闲时的 `agent.inject()` 会用一次性的 `injection` 轮次包住其 `user/message`；没有打开的轮次时，`appendOutOfBand()` 同样会用一个轮次包住符合条件的仅日志事件。这使轮次成为唯一的持久性/回放边界：后端可以将最后一个 `turn/end` 之后的任何内容视为崩溃中断尾部，而不会丢失合法记录在轮次之间的上下文。可选的 `dsh-session/invariant` 配套插件通过 `ctx.invariants` 在开发环境中强制此不变式（消息事件若位于打开的轮次之外便会抛出）。见[轮次封闭不变式 Agent Note](../../.agents/notes/implemented/architecture/2026-06-15-turn-enclosure-invariant.md)。
+
+## 插件贡献的仅日志事件
+
+插件可以通过 declaration merging 添加额外的 `SessionEventMap` 类型。这些是**仅日志**事件：不是 `SurfaceEventType`（不携带 `surfaceOp`，不参与派生历史），但与所有事件一样，必须位于一个打开的轮次内。完整的逐事件枚举（核心与插件贡献的，含 payload 与溯源信息）见生成的[持久化日志事件目录](../persistence-catalog.md)；压缩 seam 的 `compact/*` 语义在 [compaction.md](compaction.md) 中讨论。
+
+钩子桥接层的 `hook/invoked` / `hook/result` 溯源对（来自 `@deepseek-ai/dsh-hook-protocol`）通过 `handlerId` 关联。轮次中间的钩子点（`PreToolUse`/`PostToolUse`/`UserPromptSubmit`/`Stop`）在 loop 已打开的轮次内触发，因此其 `hook/*` 记录天然位于轮次之内。`SessionStart` 不生成 `hook/*` 记录：它注入的 `user/message` 已是持久证据，而且当时没有已打开的轮次可容纳该记录（见[钩子桥接 Agent Note](../../.agents/notes/implemented/feature/2026-06-30-hook-bridges.md)）。
+
+## 持久性契约
+
+持久化后端依赖的契约如下：持久日志无损保存每个事件，**包括** `assistant/chunk`；`seq` 必须连续，因此不能从规范日志中过滤分片。后端可以为事件批次选择自己的存储编码，只要 `load` 返回与追加时完全一致的事件即可（JSONL 后端可选启用的打包分片行就是此类编码；见 [persistence.md](persistence.md)）。所有 `event.data` 都必须可序列化为 JSON；`Session.append` 会从源头强制这一要求（遇到不可序列化数据时抛出），因此错误事件绝不会进入日志，`session.events` 始终与后端可持久化的内容一致。新增携带不可序列化数据的事件类型，或破坏会话不变式配套插件所检查的轮次/步骤嵌套，会构成磁盘格式的破坏性变更。
+
+消费此契约的后端见 [persistence.md](persistence.md)。

# Skills
+English | [中文](skills.zh.md)
+
The [skill capability family](../../packages/skill) is split across three packages: the registry ([dsh-skill](../../packages/skill/skill), `ctx.skills`) merges provider catalogs; the local provider ([dsh-skill-local](../../packages/skill/skill-local)) scans project/custom/user directories; the consumer ([dsh-tool-skill](../../packages/skill/tool-skill)) owns the session-prefix catalog and model-facing `skill` tool. Skills are optional instructions, not session events, so their vocabulary lives here rather than in [core.md](core.md).
Source: [`packages/skill/skill/src/index.ts`](../../packages/skill/skill/src/index.ts), [`packages/skill/skill-local/src/index.ts`](../../packages/skill/skill-local/src/index.ts), and [`packages/skill/tool-skill/src/index.ts`](../../packages/skill/tool-skill/src/index.ts).

+# Skills
+
+[English](skills.md) | 中文
+
+[skill（技能）能力族](../../packages/skill)拆分为三个包（package）：注册表（[dsh-skill](../../packages/skill/skill)，`ctx.skills`）合并各提供方的目录；本地提供方（[dsh-skill-local](../../packages/skill/skill-local)）扫描项目/自定义/用户目录；消费方（[dsh-tool-skill](../../packages/skill/tool-skill)）拥有会话前缀目录和面向模型的 `skill` 工具。skill 是可选的指令而非会话事件，因此其词汇定义在此处而非 [core.md](core.md)。
+
+源码：[`packages/skill/skill/src/index.ts`](../../packages/skill/skill/src/index.ts)、[`packages/skill/skill-local/src/index.ts`](../../packages/skill/skill-local/src/index.ts) 与 [`packages/skill/tool-skill/src/index.ts`](../../packages/skill/tool-skill/src/index.ts)。
+
+## 提供方注册表
+
+`ctx.skills` 组合本地、内嵌、远程或其他提供方。注册是同步的；远程初始化与发现属于 `list()` 的 await 阶段。提供方对象、选项与候选项以只读方式借用，语义字段会被校验。
+
+重名按 rank、提供方顺序、本地顺序依次解决；摘要按名称排序。`list()` 拒绝时记录日志并跳过，不缓存降级后的目录；格式错误的候选项快速失败。
+
+```ts type-equiv
+/** Provider interface for one source of skills, such as local directories or a remote registry. */
+interface SkillProvider {
+ /** Unique provider name in the `ctx.skills` registry. */
+ readonly name: string
+ /**
+ * List available skill candidates for the current lookup context. Provider
+ * plugins register synchronously during `apply()`; remote initialization,
+ * authentication, and discovery are awaited inside this method. Implementations
+ * should settle promptly when `options.signal` aborts.
+ * @param options - lookup options; `cwd` selects workspace-sensitive skills and `signal` cancels work.
+ * @returns provider candidates with precedence ranks and opaque locators.
+ */
+ readonly list: (options: SkillLookupOptions) => Promise<readonly SkillCandidate[]>
+ /**
+ * Load a complete skill body for a previously listed candidate.
+ * @param candidate - the winning candidate originally returned by this provider.
+ * @param options - lookup options; `cwd` selects workspace-sensitive skills and `signal` cancels work.
+ * @returns the full skill body, or `undefined` if it is no longer loadable.
+ */
+ readonly get: (candidate: SkillCandidate, options: SkillLookupOptions) => Promise<SkillDefinition | undefined>
+}
+```
+
+## 本地发现优先级
+
+内置的本地提供方按 rank 顺序扫描各根目录：
+
+| Rank | Source | Root |
+|---|---|---|
+| 100 | `project-dsh` | `<projectRoot>/.dsh/skills` |
+| 200 | `project-agents` | `<projectRoot>/.agents/skills` |
+| 300 | `custom` | `Config.customSkillDirs` |
+| 400 | `user-dsh` | `<dshHome>/skills` |
+| 500 | `user-agents` | `<agentsHome>/skills` |
+
+项目根目录为包含 `.git` 的最近祖先目录；找不到时使用当前 cwd。当 `ctx.fs` 可用时，git-root 向上查找通过文件系统服务探测 `.git`，使远程或沙箱工作区不会回退到宿主文件系统边界。用户 DSH 根目录会跳过其 `.system` 子目录。本地提供方不附带内置系统 skill；部署方通过另一个提供方提供内置 skill。
+
+## Skill 身份
+
+skill 名称为 kebab-case（`^[a-z0-9]+(?:-[a-z0-9]+)*$`）。本地提供方接受目录包（`<name>/SKILL.md`）和扁平 Markdown 文件（`<name>.md`）。嵌套递归的 `**/SKILL.md` 发现有意不在 v1 范围内。
+
+```ts type-equiv
+/** Origin bucket for a skill contribution. The value is prompt-visible metadata, not precedence by itself. */
+type SkillSource = 'project-dsh' | 'project-agents' | 'runtime' | 'user-dsh' | 'user-agents' | 'custom' | (string & {})
+```
+
+## 摘要、候选项与完整定义
+
+`SkillSummary` 是注册表中可供模型调用的摘要形状。消费方自行选择渲染哪些字段；会话目录仅使用 `name` 和 `description`，从不使用 body 或绝对文件路径。`disableModelInvocation` 将 skill 从模型列表中隐藏，但允许受信代码按名称加载。
+
+```ts type-equiv
+/** Model-visible skill metadata returned by `ctx.skills.list()` and rendered into request guidance. */
+interface SkillSummary {
+ /** Kebab-case identifier used with the `skill` tool. */
+ readonly name: string
+ /** Short routing description shown to the model. */
+ readonly description: string
+ /** Optional extra routing guidance shown to the model. */
+ readonly whenToUse?: string
+ /** Whether the skill is hidden from model listings while remaining loadable by trusted callers. */
+ readonly disableModelInvocation?: boolean
+ /** Discovery source that produced this winning skill. */
+ readonly source: SkillSource
+ /** Provider that owns this skill body. */
+ readonly provider: string
+ /** Provider-specific base for relative resources. */
+ readonly resourceBase?: SkillResourceBase
+}
+```
+
+`SkillCandidate` 是提供方到注册表的形状。`locator` 是提供方的不透明状态；注册表只存储它并在调用获胜提供方的 `get()` 时传回。
+
+```ts type-equiv
+/** Provider catalog entry used by the registry to merge and later load skills. */
+interface SkillCandidate extends SkillSummary {
+ /** Lower ranks win duplicate skill names before provider registration order is considered. */
+ readonly rank: number
+ /** Opaque provider-owned handle passed back to `provider.get()`. */
+ readonly locator: unknown
+ /** Absolute file path when the provider has one. */
+ readonly path?: string
+ /** Parsed optional metadata object from provider-specific skill frontmatter. */
+ readonly metadata?: Readonly<Record<string, unknown>>
+}
+```
+
+`SkillDefinition` 是 `ctx.skills.get()` 返回的完整解析结果，供 `skill` 工具使用。`resourceBase` 告知工具如何为本地、URL 或提供方管理的 skill 渲染相对资源引导。
+
+```ts type-equiv
+/** Optional provider-specific base used by loaded skill bodies to resolve relative resources. */
+type SkillResourceBase =
+ | { readonly kind: 'directory'; readonly path: string }
+ | { readonly kind: 'url'; readonly url: string }
+ | { readonly kind: 'opaque'; readonly description: string }
+```
+
+```ts type-equiv
+/** Complete parsed skill definition, including the body loaded by `ctx.skills.get()`. */
+interface SkillDefinition extends SkillSummary {
+ /** Markdown instruction body after any provider-specific metadata removal. */
+ readonly content: string
+ /** Absolute file path when the skill came from disk. */
+ readonly path?: string
+ /** Parsed optional metadata object from frontmatter. */
+ readonly metadata?: Readonly<Record<string, unknown>>
+}
+```
+
+运行时 skill 使用相同的完整形状，参与相同的先到先得收集顺序。返回的 disposer 移除该贡献并使发现缓存失效。
+
+```ts type-equiv
+/** Runtime skill contribution accepted by `ctx.skills.register()`. */
+type SkillRegistration = Omit<SkillDefinition, 'provider'> & { readonly provider?: string }
+```
+
+## 查找与配置
+
+skill 查找对 cwd 敏感，因为提供方可能暴露工作区本地的 skill；可选的 signal 为调用方取消提供方的工作。提供方接收与缓存标识和加载相同的只读选项对象。取消在目录选择前后（包括缓存命中时）都会检查，并与发现和完整定义加载竞争。如果找不到 git root，本地提供方将所提供的 cwd 本身视为项目根目录。
+
+```ts type-equiv
+/** Caller context used for cwd-sensitive and abortable provider work. */

# Subagent
+English | [中文](subagent.zh.md)
+
The subagent seam — an agent delegating work to a child agent. Like [bash](bash.md) it is **one optional capability**, not part of the agent-loop spine, so its vocabulary lives here rather than in [core.md](core.md). But it differs from every other seam on one axis: **multiple provider implementations coexist** in one context, registered by name (`ctx.subagents`), where bash allows only one executor. The registry shape mirrors the [LLM adapter registry](llm-streaming.md), not the single-service bash executor.
Interface: [dsh-subagent](../../packages/subagent/subagent) (`ctx.subagents` + the vocabulary below). Implementations are sibling packages (`dsh-subagent-spawn`, `-fork`, `-acp`); the model-facing consumer is [dsh-tool-subagent](../../packages/subagent/tool-subagent). The proposal and rationale: [the subagent Agent Note](../../.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md).

+# Subagent
+
+[English](subagent.md) | 中文
+
+subagent seam：一个 agent（智能体）将工作委派给子 agent。与 [bash](bash.md) 一样，它是**一项可选能力**，不属于 agent loop（智能体循环）主干，因此其词汇定义在此而非 [core.md](core.md) 中。但它在一个维度上与其他所有 seam 不同：**同一上下文中可共存多个提供方实现**，按名称注册（`ctx.subagents`），而 bash 只允许一个执行器。注册表的形状参照 [LLM（大语言模型）适配器注册表](llm-streaming.md)，而非单服务的 bash 执行器。
+
+接口：[dsh-subagent](../../packages/subagent/subagent)（`ctx.subagents` + 下文词汇）。实现为三个兄弟包（package）：`dsh-subagent-spawn`、`-fork`、`-acp`；面向模型的消费方是 [dsh-tool-subagent](../../packages/subagent/tool-subagent)。提案与设计理由见 [subagent Agent Note（agent 决策记录）](../../.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md)。
+
+源码：[`packages/subagent/subagent/src/types.ts`](../../packages/subagent/subagent/src/types.ts)
+
+## 两类能力，两种发现方式
+
+提供方通过一个静态描述符公布其**启动时**特性，服务在 run 存在之前即行检查；如果请求依赖提供方不具备的特性，会被大声拒绝（`SubagentError('UNSUPPORTED_CAPABILITY')`），绝不会被接受后静默忽略。**运行时**特性（steering（中途引导）、恢复）则是 [`SubagentRun`](#a-live-run-subagentrun) 上的可选方法——方法的存在即为能力，TypeScript 的类型收窄即为发现机制。

+
+`signal` 是就绪前后唯一的取消通道。[subagent 组合控制 Agent Note](../../.agents/notes/implemented/feature/2026-07-12-subagent-persona-tool-filter-and-depth.md)规定 persona、live 全局工具过滤、绝对深度以及「可见性而非权限」的设计理由。

+## 终态结果：`SubagentResult`
+
+一次 run 的最终产出，由 `SubagentRun.result` resolve。`structured` 仅在请求了 `outputSchema` 且成功满足时才存在；请求 schema 不保证一定能得到它，当子 agent 失败或结束时未产出有效 capture 时，提供方可能返回 `stopReason: 'error'`。非 `completed` 的 `stopReason` 意味着 `output` 可能不完整——消费方将其映射为 `isError` 的工具结果，而非将部分输出报告为成功。
+
+```ts type-equiv
+/**
+ * The terminal outcome of a subagent run, resolved by {@link SubagentRun.result}.
+ */
+interface SubagentResult {
+ /** The child's final assistant output (the last assistant message's content). */
+ readonly output: ContentBlock[]

+ * end with `stopReason: 'error'` when the child fails or finishes without a
+ * valid capture. Shape is validated against the request schema by the
+ * provider; `unknown` here because the seam is schema-agnostic.
+ */
+ readonly structured?: unknown
+ /** Why the run ended. A non-`completed` reason means `output` may be partial. */
+ readonly stopReason: SubagentStopReason
+}
+```
+
+`SubagentStopReason` 是一个[可合并扩展的派生联合类型](core.md#the-map--derived-union-pattern)——后端可以添加变体，因此消费方应对已知 case 分支处理，将未知的终态原因视为失败：
+
+```ts type-equiv
+/**
+ * Why a subagent run ended. Merge-extensible (a backend may add variants);
+ * consumers branch on the known cases and fall through `default`. The known
+ * cases mirror the harness turn-end vocabulary so the tool layer can map a
+ * non-`completed` result to an `isError` tool result.
+ */
+interface SubagentStopReasonMap {
+ /** The child finished its turn normally. */
+ completed: 'completed'
+ /** Cancelled through the request signal or disposal. */
+ aborted: 'aborted'
+ /** Model or transport failure. */
+ error: 'error'
+ /** The child hit its token ceiling before finishing. */
+ 'max-tokens': 'max-tokens'
+ /** The child declined the task. */
+ refusal: 'refusal'
+}
+```
+
+<a id="a-live-run-subagentrun"></a>
+
+## 活跃 run：`SubagentRun`
+
+`SubagentRun` 是消费方持有的、指向一个就绪子 agent 的句柄。消费方 await `result` 并始终 dispose（资源释放）该 run，直至其完全停稳。子 agent 失败时以非 completed 的 stop reason resolve；只有不可表示的基础设施故障才会 reject。可选的 `sendMessage` 和 `resume` 方法通过自身的存在来公布运行时能力。
+
+```ts type-equiv
+/**
+ * Child handle returned only after readiness. Consumers await {@link result} and must always
+ * {@link dispose} to cancel remaining work and reach quiescence. Optional methods are runtime
+ * capability discovery; narrow their presence before calling.
+ */
+interface SubagentRun {
+ /**
+ * Parent-scoped run id. For a local run, this MUST equal the published child
+ * session id, whose `parentSession` records `request.parent.session.id`; a
+ * remote provider mints an id unique in the parent namespace.
+ */
+ readonly id: SessionId
+ /**
+ * The exact published in-process child, or `undefined` for a remote run.
+ * When present, its id is {@link id}; the provider retains no ownership
+ * implication beyond the run's ordinary {@link dispose} contract.
+ */
+ readonly localAgent: Agent | undefined
+ /**
+ * Resolves with the child's terminal {@link SubagentResult} when the run
+ * settles. Does NOT reject on a child-level failure — a model/transport
+ * failure resolves with `stopReason: 'error'` so the consumer maps it to an
+ * `isError` tool result. Rejects only on an infrastructure fault the seam
+ * cannot represent as a stop reason.
+ */
+ readonly result: Promise<SubagentResult>
+ /**
+ * Cancel remaining work, reach child quiescence, and release resources.
+ * Idempotent.
+ */
+ dispose(): Promise<void>
+ /**
+ * OPTIONAL (steering capability): send additional content to the running
+ * child between steps. Present only on providers that support live steering.
+ */
+ sendMessage?(content: ContentBlock[]): void
+ /**
+ * OPTIONAL (resume capability): send a follow-up task to a settled child,
+ * continuing its session, and return a fresh run for the continuation.
+ */
+ resume?(content: ContentBlock[]): Promise<SubagentRun>
+}
+```
+
+本地 run 必须在 `start()` fulfill 前发布一个普通子 agent/会话，将该子会话 id 作为 `SubagentRun.id` 返回，以 `localAgent` 暴露确切子 agent，并在子 agent 的 `parentSession` header 中记录 `request.parent.session.id`。运行时所有权可以把子 agent 放在 parent、提供方或 root 作用域下。远程提供方则返回 parent 作用域的生命周期 id 与 `localAgent: undefined`。
+
+## 提供方 seam：`SubagentProvider`
+
+每个提供方是一个具名的子 agent 传输层，多个提供方可以共存。服务在 `start()` 之前校验请求的启动时能力。`inheritsParentContext` 仅描述对话种子注入（`fork`：true；`spawn` 和 `acp`：false），使消费方能生成准确的面向模型的措辞，而不暗示继承了工具、服务或权限。
+
+```ts type-equiv
+/**
+ * One registered transport for running child agents. Providers are trusted
+ * same-process implementations; callers treat descriptors and returned values
+ * as borrowed immutable data.
+ */
+interface SubagentProvider {
+ /** Unique registry name (e.g. `spawn`, `fork`, `acp`). */
+ readonly name: string
+ /** The start-time features this provider supports (see {@link SubagentCapabilities}). */
+ readonly capabilities: SubagentCapabilities
+ /**
+ * Whether the child sees the parent's completed-turn prefix. This is descriptive, not a
+ * service-validated start capability: the model-facing tool derives truthful wording from it.
+ * It says nothing about tool registration, injected services, or authority inheritance.
+ */
+ readonly inheritsParentContext: boolean
+ /**
+ * Establish a child and return its handle only after publication. The
+ * service has already validated that every requested start-time capability
+ * is supported, so an implementation may assume e.g. `request.maxDepth` is
+ * honorable when present. If setup fails or `request.signal` aborts before
+ * fulfillment, the provider owns and cleans all partial resources before this
+ * promise rejects. Ownership transfers to the caller only on fulfillment.
+ */
+ start(request: SubagentStartRequest): Promise<SubagentRun>
+}
+```
+
+`start()` 仅在 run 就绪时 fulfill。服务铸造唯一 `runId`，从提供方的确切 `localAgent` 快照 `local`，观察结果，emit `subagent/start`，并返回同一个 run；rejection 意味着提供方已清理，且不会 emit 生命周期事件对。配对的 `subagent/end` 携带相同标识与最终输出或基础设施失败。两个事件都仅用于观察，每个 listener 异常都会被独立隔离。
+
+## 进程内后端：深度与种子
+
+spawn 和 fork 后端通过 `parent.ctx` 创建一个普通 agent，将取消信号传入核心创建流程，并通过 `AgentHandle` 进行 dispose。移除提供方会阻止新的 start，但不会撤销已接受的 run。每个子 agent 获得一个新的扁平作用域，而非继承父级注册。深度与 fork 种子注入复用既有的 agent 和会话词汇：
+
+- **委派深度**由持久 `SessionHeader.delegationDepth` 与可合并扩展的运行时字段 `AgentOptions.subagentDepth` 共同表示；缺失表示顶层深度为零，存在的较大值具有权威性。两个字段都归该 seam 所有——循环既不设置也不读取它们——因此进程内子 agent 会持久保存 parent 深度 + 1，恢复无法降低深度，而且每次 start 都会拒绝超出安全整数域、或高于已定义绝对 `request.maxDepth` 上限的派生深度。
+- **Fork 种子注入**使用 `CreateAgentOptions.seed`（一个 `SessionEvent[]` 前缀，经由 `AgentLoop.createAgent` → `ctx.sessions.prepare({ seed })` 传递，与 `resume` 使用的原语相同）。fork 后端传入父级日志的一段*平衡的已完成轮次前缀*——父级事件直到并包括其最后一个 `turn/end`——因此种子从 0 连续，[invariants](../../packages/support/invariants) 回放可以接受它（进行中的、未平衡的轮次被排除在外）。

+
+源码：[`packages/core/system-prompt/src/index.ts`](../../packages/core/system-prompt/src/index.ts)。

+## 组装上下文
+
+`AssembleContext` 标识一次组装所解析的作用域 layer，并可携带该请求的显式控制 signal。它可合并扩展：`dsh-agent` 添加可选的 live `agent` 字段，`assembleContextFor(agent, signal)` 则一起设置这些显式字段。裸组装既没有 scope，也没有 signal。
+
+```ts type-equiv

[core.md](core.md) introduces `ToolDefinition` as the one pipeline-authoring type promoted to the spine and `ToolSchema` as the model-facing wire shape. This page owns the full `ToolDefinition`, the typed schema DSL that builds it, the guarded execution shapes, and the UI-presentation vocabulary.

How a tool wants its call shown in a UI (an editor tool-call card, a CLI log line), provider-neutral so a tool describes itself without depending on any client protocol. `presentCall`/`presentResult` return a **`card`-tagged render intent** — a discriminated union a UI bridge switches on:
- `ToolCallView` (pending): `{ card: 'generic', title, kind?, rawInput?, content?, locations? }` (the default card; `locations` is `{ path, line? }[]` files the call reads/modifies, for editor follow-along), `{ card: 'terminal', title, description?, cwd? }` (a shell command → a terminal card), or `{ card: 'diff', title, diffs, locations? }` (a file create/modify → an inline diff card; `diffs` is `{ path, oldText, newText }[]`, `oldText: null` for a new file).
-- `ToolResultView` (completed): `{ card: 'generic', title?, content? }`, `{ card: 'terminal', title?, output?, exitCode?, signal? }` (the captured run output + exit; a capable UI shows an exit-status pill, an incapable one gets a fenced ` ```console ` fallback the bridge derives from `output`), or `{ card: 'diff', title?, diffs }` (a completed file mutation → the change to show, typically the applied hunks with context lines computed from the before/after content, or a whole-file diff when there is no before-image — e.g. a file create. A `tool_call_update`'s content REPLACES the call's content, so a mutation tool returns this even when it duplicates the call-time snippet, to keep the result from clobbering the diff with result text).

The design is pinned in [the render-intent-union Agent Note](../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md); the ACP bridge maps a `diff` card to a `{ type: 'diff' }` content block, a `terminal` card to the `_meta` terminal convention, and relativizes a file card's title against the session cwd.

+## `ToolDefinition` — 一个已注册的工具
+
+由一个 `ToolSchema`（面向模型的字段）、必需的规范输出声明、`execute` 函数、仅供宿主使用的调度器元数据、可选的最终内容回调和可选 UI 展示函数组成。注册表持有这些定义，循环通过它们分派调用。注册表的 `schemas()` 通过显式允许列表构建面向模型的 `ToolSchema[]`；`output`/`execute`/`finalizeContent`/`timeoutMs`/`isConcurrencySafe`/`presentCall`/`presentResult` 绝不能泄漏到模型请求中。
+
+```ts type-equiv
+/** Tool-owned canonical output contract used after the body returns a JSON value. */

+ presentResult?(args: unknown, result: ToolResult): ToolResultView | undefined
+}
+```
+
+`execute` 接收 `args: unknown`——原始的 `ToolDefinition` 自行校验输入。第一方工具不需要手写校验；它们使用 `defineTool`，由后者代为校验并收窄参数类型、根据 `output.schema` 推导函数体返回类型，并为两个输出投影器提供类型约束。`finalizeContent` 特意接收不可变的执行对象而非类型化参数，因为无效输入和外层流水线失败也会到达该回调；它可以施加工具自有的内容限制，同时保留 `isError`、规范值、结构化错误身份、延迟上下文与展示元数据。
+
+## 统一的 JSON 值 schema DSL
+
+插件作者使用同一套词汇描述类型化参数和类型化输出值。`ValueSchemaSpec` 支持 `string`、`number`、`integer`、`boolean`、`null`、`array`、`object`、仅作者侧可用的 `json`，以及要求恰好命中一个分支的 `oneOf`；标量 `enum` 和 `const` 值必须与节点类型匹配。显式对象节点始终声明 `additionalProperties: true | false`。参数定义仍是隐式的开放对象属性映射，每个必填属性都附带 `required: true`。
+
+源码：[`packages/core/tools/src/schema.ts`](../../packages/core/tools/src/schema.ts)
+
+```ts type-equiv
+/** One author-facing schema for any lossless JSON value root. */
+type ValueSchemaSpec =
+ | StringValueSchemaSpec
+ | NumberValueSchemaSpec
+ | IntegerValueSchemaSpec
+ | BooleanValueSchemaSpec
+ | NullValueSchemaSpec
+ | ArrayValueSchemaSpec
+ | ObjectValueSchemaSpec
+ | JsonValueSchemaSpec
+ | OneOfValueSchemaSpec
+```
+
+```ts type-equiv
+/** One implicit parameter-root property, optionally required. */
+type ParameterPropertySpec = ValueSchemaSpec & { required?: true }
+```
+
+```ts type-equiv
+/**
+ * Tool parameter schema. The map itself is an implicit open object root;
+ * requiredness remains a per-property `required: true` annotation.
+ */
+type ParameterSchemaSpec = {
+ [key: string]: ParameterPropertySpec
+ [key: symbol]: never
+}
+```
+
+`{ type: 'json' }` 推导为 `JsonValue`，并编译成仅含注解、不施加约束的原始 schema。输出根可以是对象、数组、标量或 null。`InferValue<S>` 在 16 层容器内保留字面量约束与对象开放性，之后回退为 `JsonValue`，避免耗尽 TypeScript 的类型实例化栈。`InferArgs<P>` 依据逐属性的必填标记生成必填和可选的字符串键：
+
+```ts type-equiv
+/**
+ * Infer the TypeScript value accepted by an author-facing value schema. Exact
+ * inference is bounded to 16 container levels, then falls back to `JsonValue`.
+ */
+type InferValue<S> = InferValueAt<S, []>
+```
+
+```ts type-equiv
+/** Infer the TypeScript argument object for an implicit parameter schema. */
+type InferArgs<S> = InferProperties<S, []>
+```
+
+`defineTool({ name, description, parameters, output, execute, … })` 将参数推导与 `parameterSchemaSpecToJsonSchema()` 和 `validateArgs()` 绑定，并将 `execute`/`render`/`presentationMeta` 与 `InferValue<OutputSchema>` 绑定。Schema 记录只包含自有且可枚举的字符串键，schema 数组是稠密的内建数组，因此推导、编译与校验观察到的是同一份声明。精确推导保持到 16 层容器，之后放宽为 `JsonValue`；运行时校验仍会继续遍历完整 schema。`valueSchemaSpecToJsonSchema()` 通过同一套已强制执行的原始子集编译输出声明。参数不匹配时抛出 `ToolArgsError`（`INVALID_ARGS`）；函数体或后置策略产生的值无效时抛出 `ToolOutputError`（`INVALID_TOOL_OUTPUT`）。两者都经由常规工具错误路径处理。原始 JSON Schema 默认保持开放；不支持的关键字会被拒绝，而不会在未强制执行的情况下获准进入。
+
+注册是一个受信任的同进程契约。注册表以 readonly 输入借用类型化定义，要求它声明 `output`，校验其原始 schema，并检查 `timeoutMs` 必须为正有限值等语义要求；`schemas()` 在模型边界处物化显式的面向模型投影，使执行和展示共享同一份已解析定义，而不会将回调泄漏到协议上。
+
+## `ToolRestriction` — 单个作用域的实时全局过滤器
+
+`ToolRestriction` 仅作用于实时的部署全局工具层。注册表将 readonly 名称编译为私有集合，对多个限制取交集，再叠加作用域本地工具。仅 deny 的过滤器允许后续未列出的全局工具通过，而 allow 列表则排除它们。
+
+```ts type-equiv
+/**
+ * Per-scope filter over global tools. Restrictions intersect and do not affect
+ * scoped registrations or the reserved Code Mode transport.
+ */
+interface ToolRestriction {
+ /** Global tool names that stay visible; everything else is removed. */
+ readonly allow?: readonly string[]
+ /** Global tool names removed from visibility. */
+ readonly deny?: readonly string[]
+}
+```
+
+## 执行：可扩展的 waterfall（瀑布式事件）加单调策略
+
+`ctx.tools.execute()` 接受由调用方拥有且包含必需 readonly `signal` 的 `ToolExecutionInput`，将其解析后的 JSON 参数一次性物化为流水线拥有的 `ToolExecution`，然后让调用依次经过 `tools/pre-execute`（可重排的 allow/deny/ask waterfall）→ 已注册的单调 guard → `tools/execute`（环绕分派包装层）→ `tools/post-execute`（检查/替换结果）→ 可选且由定义拥有的 `finalizeContent` → `tools/result`（不可变的权威结果）。只有 `tools/execute` 视图可以替换必需的 signal。最终产出为 `ToolExecutionResult`。
+
+```ts type-equiv
+/** Opaque call identity that permits correlation without exposing mutable execution state. */
+type ToolExecutionToken = symbol & { readonly [toolExecutionTokenBrand]: true }
+```
+
+```ts type-equiv
+/**
+ * Caller-supplied description of one tool call. {@link ToolRegistry.execute}
+ * adds the registry-owned token to form a pipeline {@link ToolExecution};
+ * callers do not choose that token.
+ */
+interface ToolExecutionInput {
+ readonly callId: CallId
+ readonly name: string
+ /** Losslessly JSON-serializable parsed arguments (tools validate their own schema). */
+ readonly arguments: unknown
+ /** The agent on whose behalf the call runs (set by the agent loop). */
+ readonly agent?: Agent
+ /**
+ * Opaque token of the enclosing transport execution, when one exists. Code
+ * Mode sets this on SDK sub-dispatches so commit-style observers can wait for
+ * the outer `run_code` outcome without receiving its live mutable execution.
+ */
+ readonly parent?: ToolExecutionToken
+ /** Required caller-owned cancellation for this invocation. */
+ readonly signal: AbortSignal
+}
+```
+
+工具函数体接收运行时扩展。`deferContext()` 是组合工具的通道：它记录嵌套分派产生的上下文，而不会在外层调用尚未结束时注入这些上下文。
+
+```ts type-equiv
+/**
+ * Runtime context handed to a tool implementation after the registry has
+ * accepted a {@link ToolExecution}. A composite tool uses
+ * {@link deferContext} to ferry context produced by nested dispatches back to
+ * the outer result; the loop appends it only after the outer `tool/result`.
+ */
+interface ToolRunContext extends ToolExecution {
+ /**
+ * Defer one nested-dispatch context until this tool's final result reaches
+ * the agent loop. Contexts retain their individual source and metadata and
+ * are emitted in call order.
+ */
+ deferContext(context: HookContext): void
+}
+```
+
+agent loop（智能体循环）向注册表查询每个待处理调用的执行模式，并据此形成独占屏障和滚动池并行执行：
+
+```ts type-equiv
+/**
+ * Scheduling mode for one pending call. `parallel` may overlap with siblings;
+ * `exclusive` runs alone and forms an ordering barrier.
+ */
+type ToolExecutionMode =
+ | { kind: 'parallel' }
+ | { kind: 'exclusive' }
+```
+
+```ts type-equiv
+/**
+ * One pending tool call inside the registry pipeline. Parsed arguments cross
+ * one lossless-JSON materialization boundary before policy and are deep-frozen;
+ * call identity, the caller signal, and the registry-assigned {@link token} are
+ * readonly. The registry freezes the complete object before `tools/result`
+ * observers run.
+ */
+interface ToolExecution extends ToolExecutionInput {
+ /** Registry-assigned identity shared with nested calls only as their opaque `parent` token. */
+ readonly token: ToolExecutionToken
+}
+```
+
+```ts type-equiv
+/**
+ * Around-dispatch view of a {@link ToolExecution}. A `tools/execute` wrapper
+ * may replace the signal for its delegated lifetime, but it cannot remove it.
+ * The registry fuses every replacement with the captured caller signal.
+ */
+interface ToolDispatchExecution extends Omit<ToolExecution, 'signal'> {
+ /** Cancellation signal visible to the next wrapper or tool body. */
+ signal: AbortSignal
+}
+```
+
+`ToolExecutionToken` 是不透明的运行时 `Symbol`，仅用于身份比较。策略执行前，`execute()` 会物化并冻结参数、拒绝非 JSON 输入并分配 token。身份字段、调用方必需的 signal 和可选的 parent token 均保持 readonly。`ToolDispatchExecution` 包装层可以替换 signal 但不能移除；注册表会在调用工具函数体前重新融合调用方的 signal。最终观察者接收冻结的执行身份。
+
+`ToolGuard` 是感知作用域的最终预分派策略。其形状有意不包含 allow 结果：`undefined` 保留 waterfall 的决策，而返回的 reason 只能缩减权限，因此后续监听器无法撤销它。
+
+```ts type-equiv
+/**
+ * A monotonic execution guard evaluated after every `tools/pre-execute`
+ * listener and before the tool body. Returning a reason denies the call;
+ * returning `undefined` leaves it unchanged. Because guards have no allow
+ * result, listener ordering cannot turn a denial back into permission.
+ * @param execution - the identity-protected call after extensible pre-execute policy completed.
+ * @returns a final denial reason, or `undefined` to leave the call allowed.
+ */
+type ToolGuard = (execution: Readonly<ToolExecution>) => string | undefined
+```
+
+```ts type-equiv
+/** Canonical failure detail; internal routing information remains optional. */
+interface ToolFailure {
+ /** Human-readable failure message without the Native `Error: ` envelope. */
+ message: string
+ /** Internal error class/code used by policy and durable diagnostics. */
+ info?: ToolErrorInfo
+}
+```
+
+```ts type-equiv
+/** Successful canonical tool execution, including its Native/model projection. */
+interface ToolExecutionSuccess {
+ readonly isError: false
+ /** Execution-local canonical value; deliberately omitted from durable events. */
+ readonly value: JsonValue
+ readonly content: ContentBlock[]
+ readonly error?: never
+ readonly meta?: JsonValue
+ readonly additionalContexts?: HookContext[]
+}
+```
+
+```ts type-equiv
+/** Failed canonical tool execution; failures never carry a successful value. */
+interface ToolExecutionFailure {
+ readonly isError: true
+ readonly error: ToolFailure
+ readonly value?: never
+ readonly content: ContentBlock[]
+ readonly meta?: JsonValue
+ readonly additionalContexts?: HookContext[]
+}
+```
+
+```ts type-equiv
+/** The discriminated, execution-local outcome of one tool call. */
+type ToolExecutionResult = ToolExecutionSuccess | ToolExecutionFailure
+```
+
+结果仅承载产出。调用身份保留在不可变的 `ToolExecution` 上，后者伴随结果经过每个钩子，并出现在持久化的 `tool/call` / `tool/result` 会话事件上，因此包装层无法创建第二个相互矛盾的身份。规范的 `value` 仅存在于执行期间：循环只持久化 `content`、`error` 和 `meta`，`tool/code-dispatch` 则存储有界摘要。回放可以重现展示，却无法重建中间值。
+
+成功时，注册表会快照并校验函数体返回值，将其冻结，然后调用纯渲染器；对于直接的外层调用，还会调用可选的元数据投影器。注册表会在 `tools/result` 之前另行物化持久展示字段；无效值、渲染器/投影器失败或非 JSON 展示都会转为 JSON 安全的 `isError`。因此，最终实时观察者能看到精确的执行期值，以及可安全用于后续持久追加的字段。
+
+在得到最终内容之前，注册表会物化候选结果；若内容、结构化错误、附加上下文或展示元数据无法物化，则会转为仍可到达 `finalizeContent` 的 JSON 安全 `isError` 结果。注册表恰好调用该回调一次，随后在 `tools/result` 之前立即物化并冻结已接受的结果，因此实时观察到的产出可安全用于后续持久化的 `tool/result` 追加。
+
+每个拦截 waterfall 返回一个类型化的 **Decision**（与 `agent/*` seam 共享的惯用模式）。`tools/pre-execute` 监听器接收 `(exec, next)` 并返回 `PreToolDecision`；`tools/execute` 包装层返回 `ToolExecutionResult`；`tools/post-execute` 监听器接收 `(exec, result, next)` 并返回 `PostToolDecision`：
+
+```ts type-equiv
+/**
+ * Pre-dispatch decision. `allow` runs the call; `deny` materializes an error;
+ * `ask` runs only after an approval service returns `allowed-once` and otherwise
+ * denies. Input rewriting is excluded because arguments are already logged and
+ * presented.
+ */
+type PreToolDecision =
+ | { kind: 'allow' }
+ | { kind: 'deny'; reason: string }
+ | { kind: 'ask'; reason?: string }
+```
+
+```ts type-equiv
+/**
+ * Post-dispatch decision: accept, replace one projection, attach context for the
+ * next request, or block by turning corrective feedback into an error result.
+ */
+type PostToolDecision =
+ | { kind: 'accept'; content?: ContentBlock[]; value?: never; additionalContexts?: HookContext[] }
+ | { kind: 'accept'; value: JsonValue; content?: never; additionalContexts?: HookContext[] }
+ | { kind: 'block'; feedback: ContentBlock[]; additionalContexts?: HookContext[] }
+```
+
+调用 `next()` 获取默认决策，或直接返回一个决策以短路。前置策略可以 deny 或 ask；只有 `allowed-once` 才继续执行，而未授权、缺少审批通道或服务、或无 agent 的请求都会变为拒绝。Guard 仍可施加最终拒绝。参数不可被改写，因为历史记录、审计、UI 和执行必须保持一致。
+
+后置策略可以替换内容或值，但不能同时替换两者。替换内容会保留规范值和现有元数据；替换值会重新校验并重新计算内容/元数据；阻止会移除值，并转为包含纠正反馈的 `isError`。内容替换是展示策略，而非保密策略；需要隐藏程序化值的监听器必须阻止或替换该值。`tools/result` 在归一化后接收冻结的执行和结果；观察者无法对其进行变换，观察者的失败也会被隔离。未知工具和抛出异常的工具都会变为结构化错误（`ToolNotFoundError` 映射为 `UNKNOWN_TOOL`），调用失败但不终止当前轮次。
+
+## 已强制执行的原始 JSON Schema 子集
+
+subagent、工作流、MCP 和动态注册提供的原始 schema 使用作者侧 DSL 在协议层的对应表示。`assertSupportedJsonSchema()` 接受任意 JSON 根，`validateJsonSchemaValue()` 强制执行该 schema，`JsonSchemaError` 则报告每条不受支持或格式错误的 schema 路径。仅含注解的空节点表示不受约束的无损 JSON。`oneOf` 至少要求两个分支，且一个值必须恰好匹配其中一个。仍要求对象根的消费方调用 `assertObjectJsonSchema()` 并携带 `ObjectJsonSchema`；这样，subagent/工作流中由调用方定义的结构化输出可以继续以对象为根，而不会限制共享词汇。
+
+```ts type-equiv
+/** Scalar JSON values supported by `enum` and `const`. */

+## 工具展示 UI 词汇
+
+工具希望其调用在 UI 中如何呈现（编辑器工具调用卡片、CLI（命令行界面）日志行），提供方无关，使工具在不依赖任何客户端协议的情况下描述自身。`presentCall`/`presentResult` 返回一个 **`card` 标签的渲染意图**——一个可辨识联合类型，UI 桥接层据此分发：
+
+- `ToolCallView`（待执行）：`{ card: 'generic', title, kind?, rawInput?, content?, locations? }`（默认卡片；`locations` 是 `{ path, line? }[]`，表示调用读取/修改的文件，供编辑器跟随）、`{ card: 'terminal', title, description?, cwd? }`（shell 命令→终端卡片）、或 `{ card: 'diff', title, diffs, locations? }`（文件创建/修改→行内 diff 卡片；`diffs` 是 `{ path, oldText, newText }[]`，新文件时 `oldText: null`）。
+- `ToolResultView`（已完成）：`{ card: 'generic', title?, content? }`、`{ card: 'terminal', title?, output?, exitCode?, signal? }`（捕获的运行输出 + 退出状态；有能力的 UI 显示退出状态标签，其他 UI 可以派生围栏 ` ```console ` 回退）、或 `{ card: 'diff', title?, diffs }`（已完成的文件变更→要展示的变更，通常是从变更前后内容计算出带上下文行的已应用 hunk，或在没有前像时的整文件 diff）。已完成视图会替换待执行视图，因此变更工具即使与调用时的片段重复也要返回 diff 结果。
+

+
+[dsh-user-interaction](../../packages/ui/user-interaction) 的用户交互 seam。它是工具或权限插件需要人类回答后 agent（智能体）才能继续时所使用的、提供方无关的词汇。UI surface 提供活跃的 `UserInteractionProvider`；`dsh-tui` 使用键盘驱动的 overlay，host 运行时把请求转发给它连接的客户端。
+
+源码：[`packages/ui/user-interaction/src/index.ts`](../../packages/ui/user-interaction/src/index.ts)
+
+## 问题选项
+
+`AskUserQuestionOption` 是可选择项的形状。`label` 是面向用户的选项文字，同时也是面向模型的选中值；`description` 是可选的 UI 帮助文本。
+
+```ts type-equiv
+/** One selectable answer offered to the user. */
+interface AskUserQuestionOption {
+ /** User-facing label. */
+ label: string
+ /** Optional extra context rendered by capable UIs. */
+ description?: string
+}
+```
+
+## 问题条目
+
+`AskUserQuestionItem` 是请求中的一个问题。调用方提供稳定的 `id`，它会随答案原样返回，使批量问题仍可路由。可选的 `detail` 携带辅助文本；提供方会将其随问题渲染，但不会放入可选 option label。
+
+```ts type-equiv
+/** One question in a user-interaction request. */
+interface AskUserQuestionItem {
+ /** Stable caller-provided question id, echoed in the answer. */
+ id: string
+ /** The question to display. */
+ question: string
+ /** Optional supporting detail rendered with the question but kept out of option labels. */
+ detail?: string
+ /** Optional short heading/group label. */
+ header?: string
+ /** Optional choices the UI can render as a menu. */
+ options?: AskUserQuestionOption[]
+ /** Whether more than one option may be selected. Defaults to single-select. */
+ multiSelect?: boolean
+}
+```
+
+## 提问请求
+
+`AskUserQuestionRequest` 是跨包（package）的请求。`questions` 是数组，这样 UI 可以在一个流程中呈现相关提示，同时保持每个回答有稳定的 id。
+
+```ts type-equiv
+/** Request for a human answer. */
+interface AskUserQuestionRequest {
+ /** Questions to display. */
+ questions: AskUserQuestionItem[]
+ /** Calling agent, when the request came from an agent tool call. */
+ agent?: Agent
+ /** Abort signal for the owning tool/step. */
+ signal?: AbortSignal
+}
+```
+
+## 回答
+
+提供方为每个问题 id 返回一个回答项。`selected` 包含选中的选项标签，`custom` 在用户输入自由文本时携带「其他」回答。当 `custom` 存在时，`selected` 为空；自定义文本是对选中项的覆盖，而非补充。UI 也可以使用 `selected` 为空且不含 `custom` 的回答项，在其余问题均已完成的批次中保留被跳过的问题。
+
+```ts type-equiv
+/** Answer to one question. */
+interface AskUserQuestionAnswerItem {
+ /** The answered question id. */
+ id: string
+ /** Selected option labels. Empty for custom or unanswered choices. */
+ selected: string[]
+ /** Optional free-text "Other" answer. */
+ custom?: string
+}
+```
+
+```ts type-equiv
+/** The human's answer. */
+interface AskUserQuestionAnswer {
+ /** Structured answers keyed by question id. */
+ answers: AskUserQuestionAnswerItem[]
+}
+```
+
+## 提供方
+
+同一上下文中只能有一个活跃的提供方。提供方注册绑定到 effect，因此 HMR（热模块替换）或 dispose（资源释放）会移除当前活跃的 UI。
+
+```ts type-equiv
+/** UI-side provider for user questions. */
+interface UserInteractionProvider {
+ ask(request: AskUserQuestionRequest): Promise<AskUserQuestionAnswer>
+}
+```
+
+## 错误
+
+`UserInteractionError` 继承 `HarnessError`，因此 `ctx.tools.execute()` 会保留 `{ name, code }`，用于面向模型的工具失败，如 `EMPTY_QUESTIONS`、`NO_PROVIDER`、`ASK_ABORTED` 或 UI 侧取消。
+
+```ts type-equiv
+/** Stable error taxonomy for user-interaction failures. */
+class UserInteractionError extends HarnessError {
+ constructor(message: string, code: string, options?: ErrorOptions) {
+ super(message, code, options)

The web access seam — a [capability seam](../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.md) that spans **two capabilities** (search and fetch) on one `ctx.web` service, split across packages: interface ([dsh-web](../../packages/web/web), `ctx.web` + the provider registries), implementations ([dsh-web-search-exa](../../packages/web/web-search-exa), [dsh-web-search-perplexity](../../packages/web/web-search-perplexity), [dsh-web-search-deepseek](../../packages/web/web-search-deepseek), [dsh-web-fetch-local](../../packages/web/web-fetch-local)), and consumer ([dsh-tool-web](../../packages/web/tool-web), the `web_search`/`web_fetch` tool schemas). Web is **one optional capability**, not part of the agent-loop spine — so its vocabulary lives here, not in [core.md](core.md). A search-provider swap does not change how the model asks for a query, and a fetch-implementation swap does not change how the model asks for a URL.

+# Web 访问
+
+[English](web.md) | 中文
+
+Web 访问 seam 是一个[能力 seam](../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.md)，在同一个 `ctx.web` 服务上横跨**两项能力**（search 与 fetch），并拆分到多个包（package）：接口（[dsh-web](../../packages/web/web)，`ctx.web` + 提供方注册表）、实现（[dsh-web-search-exa](../../packages/web/web-search-exa)、[dsh-web-search-perplexity](../../packages/web/web-search-perplexity)、[dsh-web-search-deepseek](../../packages/web/web-search-deepseek)、[dsh-web-fetch-local](../../packages/web/web-fetch-local)）与消费方（[dsh-tool-web](../../packages/web/tool-web)，即 `web_search`/`web_fetch` 工具 schema）。Web 是**一项可选能力**，不属于 agent loop（智能体循环）主干，因此其词汇定义在此而非 [core.md](core.md) 中。更换 search 提供方不会改变模型请求 query 的方式，更换 fetch 实现也不会改变模型请求 URL 的方式。
+
+源码：[`packages/web/web/src/types.ts`](../../packages/web/web/src/types.ts)
+
+## 为什么两项能力合为一个 seam
+
+搜索与抓取既不共享请求 schema，也不共享业务逻辑，但它们被有意设计为同一个 `ctx.web` 中间层：一个提供方选择策略的所有者、一套 abort/error 词汇、一个面向产品的「此 harness 如何访问 Web」配置界面。代价是服务上并行的 `searchX`/`fetchX` 方法对；这种并行是有意为之，而非遗漏的提取。提供方注册的是**能力**（`WebSearchProvider` 或 `WebFetchProvider`），而非工具；面向模型的名称、schema、提示词引导与展示全部集中在唯一的消费方 `dsh-tool-web` 中。
+
+## 搜索请求与结果
+
+面向模型的工具参数仅为一个 `query`；`maxResults` 是消费方自有的上限（`dsh-tool-web` 的 `searchMaxResults` 配置，默认 `8`），通过 seam 传递并在返回时强制执行——如果提供方返回超量，seam 截断 `sources[]` 并设置 `truncated`。
+
+```ts type-equiv
+/**
+ * What one search-capable backend can return. The model-facing argument is just
+ * a query; `maxResults` is a `dsh-tool-web`-layer bound passed through unchanged
+ * and enforced on the way back by the seam (see {@link WebSearchResult}).
+ */
+interface WebSearchRequest {
+ readonly query: string
+ /**
+ * Upper bound on returned sources; the seam truncates to it. Omitted = no
+ * bound. `dsh-tool-web` always sets it. A provider whose API supports a
+ * result-count control (Exa's `numResults`) should apply it at the request
+ * layer as a cost/latency optimization; the seam enforces the bound
+ * regardless.
+ */
+ readonly maxResults?: number
+}
+```
+
+```ts type-equiv
+/**
+ * Normalized search outcome. `content` is optional provider-generated answer
+ * text or summary (Exa returns none; Perplexity returns a generated answer).
+ * `sources[]` is the portable citation surface. `truncated` is set by the seam
+ * when it cut `sources[]` down to `maxResults`.
+ */
+interface WebSearchResult {
+ /** Optional provider-generated answer text, search context, or summary. */
+ readonly content?: string
+ /** Citeable sources, already truncated to the request's `maxResults`. */
+ readonly sources: readonly WebSearchSource[]
+ /** True when the seam dropped sources to honor `maxResults`. */
+ readonly truncated: boolean
+}
+```
+
+`content` 是提供方可选生成的回答文本（Exa 和 DeepSeek 不返回；Perplexity 返回生成式回答）。`sources[]` 是一套可跨提供方使用的引用数据结构。一个 source 必有 `url`；`title`/`snippet`/`publishedAt` 可选，因为并非每个提供方都返回它们——Perplexity 的引用可能只有 URL，强迫适配器编造其余字段会让 seam 说谎。`dsh-tool-web` 渲染时使用 `title ?? hostname(url)`。
+
+```ts type-equiv
+/**
+ * One citeable source. A source always has a URL; `title`, `snippet`, and
+ * `publishedAt` are optional because not every provider returns them — forcing
+ * adapters to invent them would make the seam lie (Perplexity citations may be
+ * URL-only). `dsh-tool-web` renders `title ?? hostname(url)` for display.
+ */
+interface WebSearchSource {
+ readonly url: string
+ readonly title?: string
+ readonly snippet?: string
+ /** Publication/crawl timestamp as a provider-supplied ISO-8601 string. */
+ readonly publishedAt?: string
+}
+```
+
+## 抓取请求与结果
+
+```ts type-equiv
+/**
+ * What one fetch-capable backend is asked to retrieve. The request deliberately
+ * omits timeout, format, prompt, and extraction controls: cancellation is a
+ * direct execution argument, while presentation and higher-level LLM concerns
+ * belong outside safe retrieval.
+ */
+interface WebFetchRequest {
+ readonly url: string
+}
+```
+
+HTTP 状态码是被抓取资源状态的一部分，不自动视为失败：成功的网络抓取返回 `404`/`500` 时，仍产出一个带状态码和有界解码 body 的 `WebFetchResult`。`url` 是经过允许的重定向后的最终 URL。`WebError` 仅用于无法安全获取或表示资源的情况。
+
+```ts type-equiv
+/**
+ * Normalized fetch outcome. A successful network fetch of a non-2xx response is
+ * a result, not an error: the status code is part of the fetched resource
+ * state. {@link WebError} is reserved for failures to safely retrieve or
+ * represent the resource.
+ */
+interface WebFetchResult {
+ /** The final URL after allowed redirects (the request URL is in the request). */
+ readonly url: string
+ /** HTTP status code of the fetched response. */
+ readonly statusCode: number
+ /** Decoded body, classified by content kind. */
+ readonly body: WebFetchBody
+ /** True when the provider capped the decoded body. */
+ readonly truncated: boolean
+}
+```
+
+`WebFetchBody` 是 `dsh-web` 拥有的**封闭**可辨识联合类型（不是可合并扩展的 map）：提供方解码 kind，`dsh-tool-web` 渲染它，因此新增一个 kind 是已知包之间的协调变更，而非插件扩展。消费方对 `kind` 做 `switch` 并以 `default: assertNever(...)` 结尾，所以新增 kind 会在每个消费方处编译失败，直到被处理。即使各分支当前字段一致，每个分支仍保持独立的对象字面量，为将来分支特有字段留出空间（例如未来 `pdf` body 的 `pageCount`）。
+
+```ts type-equiv
+/**
+ * The decoded body of a fetched resource. A CLOSED discriminated union owned by
+ * `dsh-web`: the provider decodes the kind and `dsh-tool-web` renders it, so a
+ * new kind is a coordinated change across known packages, not a plugin
+ * extension. Consumers `switch` on `kind` ending in `default: assertNever(...)`
+ * so adding a kind breaks compilation at every consumer until handled. Each arm
+ * stays its own object literal even where fields coincide today, leaving room
+ * for arm-specific fields later (a `pdf` body's `pageCount`).
+ */
+type WebFetchBody =
+ | { readonly kind: 'html'; readonly content: string }
+ | { readonly kind: 'text'; readonly content: string }
+```
+
+## 提供方可用性
+
+提供方的 `available(): boolean` 是一个廉价的本地检查（凭证是否存在、配置是否可解析），**禁止发起网络调用**。它是执行时选择的输入，而非健康检查系统：`search()`/`fetch()` 读取它以选出可用的提供方，选择失败以结构化的 `WebError` 呈现给调用方路由——其 code 和 message 携带可分支的细节（缺失的 id 或有歧义的候选集）。
+
+选择从不依赖注册顺序、配置顺序或 HMR（热模块替换）顺序：一项能力要么有显式的提供方 id（配置 `searchProvider`/`fetchProvider`，或填充同一字段的对应环境变量），要么在恰好只有一个可用提供方注册时自动选择；多个可用提供方且未配置 id 时为 `WEB_PROVIDER_AMBIGUOUS`，而非先注册先赢。
+
+## 错误
+
+`WebError extends HarnessError`（[core.md](core.md) 错误分类体系），带有 `code: string`（开放式，与其他 seam 的错误一致——`LlmError`、`SubagentError`），而非封闭联合类型：提供方可以在不修改 `dsh-web` 的情况下抛出自己的 code，消费方必须容忍未知 code。code 按所有者划分。seam 中立的 code 由 `WebService` 选择逻辑和共享契约抛出：`WEB_PROVIDER_UNAVAILABLE`、`WEB_PROVIDER_CONFIGURED_MISSING`、`WEB_PROVIDER_CONFIGURED_UNAVAILABLE`、`WEB_PROVIDER_AMBIGUOUS`、`WEB_DUPLICATE_PROVIDER`（注册时的编程错误，类似 `LlmService` 的 `DUPLICATE_ADAPTER`）、`WEB_ABORTED`，以及 `WEB_PROVIDER_ERROR`（提供方自身故障通过 seam 暴露的兜底 code，包括网络/传输失败——DNS、连接被拒、TLS）。抓取传输层 code 由 `dsh-web-fetch-local` 实现拥有，不同的抓取后端无需抛出它们：`WEB_INVALID_URL`、`WEB_BLOCKED_URL`、`WEB_REDIRECT_BLOCKED`、`WEB_FETCH_TOO_LARGE`、`WEB_FETCH_TIMEOUT`、`WEB_UNSUPPORTED_CONTENT_TYPE`。
+
+## 服务
+
+`WebService` 注册搜索与抓取提供方，以 `WEB_DUPLICATE_PROVIDER` 拒绝重复 id，并在执行时以结构化的选择错误解析提供方。本地抓取后端仅接受 HTTP(S)、拒绝凭证、限制重定向次数、字节数、字符数和时间、对每一跳同源重定向重新校验，并解码 body；展示由工具负责。私有网络阻断尚未实现，因此请勿在可触及敏感内部目标的环境中启用 `web_fetch`。

# Workflow

The workflow seam — an agent running a model-written orchestration SCRIPT that fans out subagents. Like [subagent](subagent.md) it is **one optional capability**, not part of the agent-loop spine, so its vocabulary lives here rather than in [core.md](core.md). Unlike the subagent registry it takes the bash shape: ONE engine implementation per context provides `ctx.workflows`; there is no named-provider registry (a second engine is a plugin swap, not a co-resident).
Interface: [dsh-workflow](../../packages/workflow/workflow) (`ctx.workflows` + the vocabulary below). The implementation is [dsh-workflow-workerthread](../../packages/workflow/workflow-workerthread) (a `node:worker_threads` engine — one worker per run, the script's vm context inside it); the model-facing consumer is [dsh-tool-workflow](../../packages/workflow/tool-workflow). The proposal and rationale: [the dynamic-workflows Agent Note](../../.agents/notes/implemented/feature/2026-07-05-dynamic-workflows.md).

+# 工作流
+
+[English](workflow.md) | 中文
+
+工作流 seam：一个 agent（智能体）运行由模型编写的编排脚本（SCRIPT），扇出 subagent。与 [subagent](subagent.md) 一样，它是**一项可选能力**，不属于 agent loop（智能体循环）主干，因此其词汇定义在此处而非 [core.md](core.md)。与 subagent 注册表不同，它采用 bash 形态：每个上下文只有一个引擎实现提供 `ctx.workflows`；没有命名提供方注册表（第二个引擎是插件替换，而非共存）。
+
+接口：[dsh-workflow](../../packages/workflow/workflow)（`ctx.workflows` + 下文词汇）。实现是 [dsh-workflow-workerthread](../../packages/workflow/workflow-workerthread)（一个 `node:worker_threads` 引擎——每个 run 一个 worker，脚本的 vm 上下文位于其中）；面向模型的消费方是 [dsh-tool-workflow](../../packages/workflow/tool-workflow)。提案与设计理由见 [dynamic-workflows Agent Note（agent 决策记录）](../../.agents/notes/implemented/feature/2026-07-05-dynamic-workflows.md)。
+
+源码：[`packages/workflow/workflow/src/types.ts`](../../packages/workflow/workflow/src/types.ts)
+
+## 启动请求
+
+调用方启动 run 时提出的请求。普通工作流工具根据模型的 `{ script, meta, args }` 调用与发起调用的 agent 构建它；专用消费方还可以为该 run 选择一个引擎级 `subagentProvider` 并调低 `maxTotalAgents`，但脚本无法观察或替换这两项策略。`meta` 与 `args` 是普通 JSON 数据（引擎会对 `meta` 做形状校验，并在任何内容运行前大声拒绝——绝不会通过求值脚本文本来获取它）。`parent` 是必填字段——脚本生成的每个子 agent 都归属于它（cwd、谱系与深度通过 [subagent seam](subagent.md) 流转）。
+
+```ts type-equiv
+/**
+ * What a caller asks for when starting a workflow run. `meta` and `args` are
+ * plain JSON DATA by the seam contract (the tool builds both from the model's
+ * schema-validated call; the engine validates `meta`'s shape and rejects loud
+ * before anything runs) — an engine never evaluates script text to obtain
+ * them. `parent` is REQUIRED — every `agent()` the script spawns is
+ * attributed to it (cwd, lineage, depth flow through the subagent seam).
+ */
+interface WorkflowStartRequest {
+ /** The plain-JS script body (top-level await allowed; ends with `return <json-value>`). */
+ script: string
+ /** The workflow's identity block, as plain JSON data (shape-validated by the engine). */
+ meta: WorkflowMeta
+ /** Optional input exposed verbatim to the script as the `args` global. */
+ args?: unknown
+ /**
+ * Optional engine-wide child-provider override for this run. The workflow
+ * script cannot observe or replace it; omission uses the engine's configured
+ * provider.
+ */
+ subagentProvider?: string
+ /**
+ * Optional per-run total-child ceiling. Implementations reject values above
+ * their deployment ceiling before publishing the run.
+ */
+ maxTotalAgents?: number
+ /** The agent on whose behalf the run executes (parent of every child). */
+ parent: Agent
+ /** Cancels the run when aborted (the tool's `exec.signal`). */
+ signal?: AbortSignal
+}
+```
+
+## 工作流的身份标识：`WorkflowMeta`
+
+作为数据附在启动请求上的身份块（工具的 `meta` 参数；字段词汇与 Claude Code 动态工作流的 meta 块一致）。`phases` 仅用于进度展示：`phase()` 调用与标题匹配，供观察者使用；不暗示任何执行结构。
+
+```ts type-equiv
+/**
+ * The script's identity block, provided as plain JSON data alongside the
+ * script body (the model-facing tool carries it as its `meta` parameter) and
+ * validated by the engine before the body runs. `name`/`description` are
+ * required; the rest is optional annotation. The field vocabulary matches the
+ * Claude Code dynamic-workflows meta block.
+ */

+ name: string
+ /** One-line description of what the workflow does. */
+ description: string
+ /** Optional guidance on when this workflow applies (shown in listings). */
+ whenToUse?: string
+ /** Optional phase declarations matched by `phase()` calls. */
+ phases?: WorkflowPhase[]
+}
+```
+
+## 终态结果：`WorkflowResult`
+
+一次运行的结果，由 `WorkflowRun.result` resolve。`value` 是脚本的物化返回值——纯宿主域 JSON 数据（脚本无返回值时为 `null`）——仅在 `completed` 时有意义。`stopReason` 是封闭联合类型（引擎所有；消费方可穷举）：`completed` | `cancelled` | `error`。非 `completed` 的原因在 `error` 中携带失败信息，消费方将其映射为 `isError` 工具结果，而非把部分输出当作成功上报。
+
+```ts type-equiv
+/**

+ * the script's materialized return value (plain host-realm JSON data; `null`
+ * when the script returned `undefined`) — meaningful only for `completed`.
+ * A non-`completed` reason carries the failure in `error`; the consumer maps
+ * it to an `isError` tool result rather than reporting partial output.

+
+```ts type-equiv
+/**
+ * Holder-owned live workflow. `result` never rejects and settles within the
+ * engine's cancellation grace; failures resolve through `stopReason`. Consumers
+ * may cancel and must call idempotent `dispose()` on every path to await bounded
+ * script settlement and child quiescence.

+ readonly result: Promise<WorkflowResult>
+ /** Cancel the run: children abort, pending hooks reject, the script dies at its next await (or is force-settled at the grace). */
+ cancel(reason?: string): void
+ /** Cancel + bounded-grace settle; safe to call on every path (idempotent). */
+ dispose(): Promise<void>
+}
+```
+
+## 失败纪律：`WorkflowError.fatal`
+
+脚本内部的钩子误用：错误参数、未知或延迟的 `agent()` 选项、超出[结构化输出子集](../../packages/core/tools/README.md)的 schema、触发的上限、seam 启动失败、取消，都会抛出 `fatal: true` 的 `WorkflowError`。`parallel()`/`pipeline()` 组合器对 fatal 错误直接重新抛出，而非将该项映射为 `null`：一个拼写错误的选项必须让脚本大声失败，绝不能消融为看似普通子 agent 失败的结果。逐项的 `null` 保留给子运行失败（非 `completed` 的 stop reason）和阶段内的普通脚本错误。
+
+## 事件
+
+`workflow/*` 事件（`workflow/start`、`workflow/phase`、`workflow/log`、`workflow/agent-start`、`workflow/agent-end`、`workflow/end`，见[事件目录](../cordis-catalog/events.md)）是**仅供观察**的 emit，携带数据快照：每个 payload 以 `WorkflowRunInfo`（id + meta）开头，而非活跃的 `WorkflowRun`，因此订阅者无法获得 `cancel`/`dispose`；`workflow/end` 刻意省略 result value（观察结果的监听器不得收到调用方 result 的可变别名）。每次 emit 对每个监听器隔离：抛出异常的订阅者被记录日志但不传播，不会饿死在它之后注册的监听器；每个监听器收到自己的 payload 克隆，因此修改它既不会损坏引擎也不会影响其他监听器。这种隔离方式与 `subagent/start`/`subagent/end` 一致。

+# 防御性模式
+
+[English](defensive-patterns.md) | 中文
+
+来之不易的缺陷类别规则：下面每条模式都是本项目实际发布或差点发布的一类缺陷，以防止其复发的规则形式陈述。在编写生命周期、并发、子进程或清理代码之前请先阅读本文。测试层面的对应规则（真实入口路径、world 验证、资源归属）见 [testing.md](testing.md)。
+
+## 正交结果独立上报
+
+一个结果可以同时具有多重性质：进程可能既超时又以 exit 0 退出，因为它捕获了信号。每个独立事实（`timedOut`、`signal`、`exitCode`）都应独立暴露；切勿将某个 flag 的上报嵌套在另一个 flag 的分支内，否则调用方会把一次被截断的运行误读为正常成功。
+
+## 跨 seam 契约两侧都要遵守
+
+当一个接口文档记录了两种合法的信号方式时——例如适配器可以通过从 `stream()` 抛出异常来报告失败，也可以通过以 `finish {kind:'error'|'aborted'}` 分片结束流来报告——消费方必须同时处理两种路径，而不是只处理第一个实现恰好使用的那种。依赖库的适配器可能无法在流中途抛出异常，只能走带内路径；如果 agent loop（智能体循环）只捕获抛出的异常，就会把提供方的 401 错误变成一个正常完成的轮次。请在类型定义处记录契约；通过真实消费方测试每个分支。
+
+## 异步状态不是同步状态
+
+`agent.followup()` 不会在返回前翻转状态；后台任务的完成与轮次边界存在竞争；`reader.close()` 在 EOF 和 dispose（资源释放）两种情况下都会触发。切勿基于一个刚刚请求的状态来控制流程——应以实际触发的事件/promise（`agent/status`、`task.done`）驱动生命周期，并观察状态转换（先看到 `running` 再看到 `idle`），而不是把状态当作逐次 `followup()` 的结果：多次排队的 `followup()` 会在同一个 `running` 区间内连续运行多个轮次，而取消或资源释放可能丢弃尚未启动的项。这条守则是双向的：如果等待的转换永远不会发生（EOF 时没有提交过任何工作 → 永远不会进入 `running`），等待就会挂起——请显式处理「无需等待」的分支。
+
+## Dispose 必须达到完全停稳，而不仅仅是请求停止
+
+一个清理流程如果发出 kill/abort 后就返回、而不等待工作实际停止，就会留下孤儿进程。请让清理逻辑异步化并 await 子进程退出（kill → await `done`），并在 kill 之前关闭监听器/通知注册表，使迟到的完成事件保持静默。测试应证明 dispose 确实等待了（`await fiber.dispose()` 之后 pid 已不存在），而不仅仅是进程最终会死。
+
+## 在边界处包容回调异常
+
+用户提供的监听器如果抛出异常，不得导致它所在的 promise 被 reject，也不得饿死排在它后面的监听器。请用 try/catch 包裹分发循环并记录日志；一个行为不当的订阅者绝不能破坏核心生命周期。
+
+## 绝不将环境变量或可预测路径暴露给不可信输出
+
+spawn 的命令应获得一份经过清洗的 env（去除 `*KEY*`/`*SECRET*`/`*TOKEN*`），使 harness 凭证无法泄漏到输出、`env` 或溢出文件中。临时/溢出文件应使用私有（0700）目录、随机文件名和排他的仅所有者可访问打开方式（`'wx'`、`0o600`）——可预测的全局可读路径会招致符号链接竞争和信息泄露。

Domain vocabulary for the DeepSeek Harness SDK uses one canonical term per concept. Terms link to their entries with standard Markdown anchors; implementation detail stays in package READMEs and Agent Notes.

+# 术语表
+
+[English](glossary.md) | 中文
+
+DeepSeek Harness SDK 的领域词汇为每个概念规定一个规范术语。各术语通过标准 Markdown 锚点链接到相应条目；实现细节留在各包（package）的 README 与 Agent Note（agent 决策记录）中。
+
+FIXME(glossary-completeness): 首次发布前扩充本术语表，使其覆盖 SDK 的其他核心与能力子系统，而非仅限于 agent scope。
+
+## agent-scope
+
+- **scope**：按 agent（智能体）划分的注册单位。一项贡献（工具、提示词片段、变量、限制、监听器）要么是*全局的*（对所有 agent 可见），要么是*有范围的*（归属于恰好一个 [scope key](#scope-key)）。只有两层，扁平结构：有范围的注册不会向下继承给 subagent；子树行为通过 [lineage](#lineage) 数据表达，从不通过 scope 结构。
+- **scope key**：scope 的不透明标识，按对象同一性比较。harness 约定：一个活跃的 agent 就是其自身 scope 的 key。<a id="scope-key"></a>
+- **agent 上下文（`agent.ctx`）**：agent 的有范围上下文；通过它进行的注册既是 scope 可见的，也是 scope 生命周期的（同一事实决定两者），其上的监听器参与该 agent 的 scope 过滤分发。注册表主体事件可以在各自的事件契约下保持故意不过滤。
+- **scope carrier**：scope 过滤分发所携带的 `thisArg`（由 `scopeTarget` 构建）；其过滤器放行无标签监听器加上主体自身的监听器。*无主体*的 carrier（没有 key）只放行无标签监听器。
+- **scoped dispatch**：规则是：关于某个 agent 活动的事件以该 agent 的 carrier 进行分发。关于注册表本身的事件（如「一个工具被添加了」）属于*注册表主体*事件，保持不过滤。
+- **shadowing**：最具体者胜出的名称解析：一个有范围的工具/片段/变量仅在该 scope 内替换同名的全局对应项。这是按 agent 定制 persona 和按 agent 定制工具变体的机制。
+- **restriction / scope-local 注册**：restriction（`tools.restrict`）为单个 scope 过滤全局工具表面（多个 restriction 取交集组合）；scope-local 注册在过滤之后合并。被过滤掉的全局工具既不出现在提示词中，也拒绝执行，与不存在的工具无法区分。
+- **setup window**：创建者组装 agent 有范围世界的创建时隙（`CreateAgentOptions.setup`）：在 scope 和 agent 对象已存在、但 agent 或会话尚未发布、`agent/session-start` 尚未触发、首次提示词尚未组装之前。setup 只做注册，从不驱动 agent。
+- **lineage**：以数据形式携带的父子关系事实（`parentSession`、持久的 `delegationDepth`、运行时 `subagentDepth`）；从不影响可见性。<a id="lineage"></a>
+
+## 目标
+
+- **目标**：附着在现有会话上的单个持久完成目标，带有按修订号演进的 `active` / `paused` / `blocked` / `complete` 阶段和 Goal Round 上限；`blocked` 保留策略代码与说明。目标是一种状态，不是调度器，也不是一段独立对话；会话日志仍是其真源。
+- **Goal Round**：为当前目标接纳的一次续行周期。同会话驱动器将 Goal Round 具体化为一个来源为目标的[轮次](#turn)，其中可包含零个或多个步骤；同一会话中无关的人类轮次不消耗 Goal Round 上限。<a id="goal-round"></a>
+- **目标激活**：续行消费方接纳下一个 Goal Round 的进程本地权限。激活态为 `armed` 或 `disarmed`；它有意不参与持久回放，因此恢复和 fork 后，必须由人类随后通过 `/goal` 或模型工具授权恢复变更，自动工作才可开始。
+
+## 人类命令
+
+- **人类命令**：以斜杠开头的指令，由面向人类的适配器通过 `ctx.commands` 解释并执行，不会成为模型消息。它既不同于面向模型的工具，也不同于通过 `ctx.bash` 执行 shell 命令。
+- **命令平面**：由 UI 适配器与命令插件拥有的发现、解析、分发、取消和结果渲染。除非处理器另行改变持久领域，否则命令输出属于 UI 状态。
+- **目标命令**：`/goal` 是由 `dsh-command-goal` 提供的人类命令；它直接观察或更改当前目标，而目标领域拥有每条持久且模型可见的记录。
+
+## 循环层级
+
+- **轮次**：会话中一次对已接纳输入的排空过程，在模型及其工具停止工作或终止策略介入后结束。<a id="turn"></a>
+- **步骤**：一次模型请求，以及由模型响应引发的工具执行；一个轮次包含零个或多个步骤。<a id="step"></a>
+- **Round**：承载一个轮次的外层策略迭代，例如一个 [Goal Round](#goal-round) 或一次使用全新 agent 的 Ralph 尝试。Round 计数器归该策略所有，并不统计会话中的每个轮次。<a id="round"></a>
+
+## Ralph
+
+- **Ralph 循环**：一次面向不可变目标的前台全新 agent 工作流运行。它是由工作流和 subagent 原语组合而成的面向模型的工具策略，不是同会话目标、agent loop（智能体循环）模式、调度器或通用工作流脚本功能。<a id="ralph-loop"></a>
+- **Ralph Round**：[Ralph 循环](#ralph-loop)中的一个全新子会话。子会话不接收父会话或此前子会话的对话种子；共享工作区和一份有界的 [Ralph 交接](#ralph-handoff)承载跨 Round 的状态。<a id="ralph-round"></a>
+- **Ralph 交接**：从一个仍需继续的 Ralph Round 传给下一个 Ralph Round 的规范化、有界结构化报告，包含状态、摘要、证据、后续步骤和阻塞说明。它补充共享工作区，而不取代工作区的权威地位。<a id="ralph-handoff"></a>

**dispose（资源释放）必须等待所有任务完全停稳，不能仅下发终止指令就返回**：如果清理过程只发出终止或中断信号，却不等任务停止就返回，就会留下孤儿进程。清理应采用异步方式，等待所有子任务彻底退出（先发出终止信号，再等待退出）；发出信号前应先关闭监听器与通知注册表，使延迟到达的完成事件不再触发通知。测试要证明 dispose 的确等到清理完成：执行完 `await fiber.dispose()` 后进程 PID 立即消失，不能只检查进程最终会自行消亡。

+# 事故复盘（postmortem） 0001：ACP（Agent Client Protocol）服务器在连接时崩溃——`export default` 丢弃了插件的 `inject`
+
+[English](0001-acp-default-export-drops-inject.md) | 中文
+
+Status: resolved (fix in PR（Pull Request） #41 `feat/acp-2-bridge`)
+
+## 摘要
+
+两个集成错误在单元测试全覆盖的情况下仍然导致 ACP 崩溃：一个 default export 使 Loader 丢弃了 `inject`，一个经 traceable 代理的可选服务查找在 shadow 边界上失败。手动挂载的测试绕过了这两条路径。修复方案增加了无需 API key 的真实 Loader 覆盖率，并为插件导出和可选服务访问制定了包（package）级规则。
+
+## 概述
+
+ACP 服务器（`examples/acp-agent`、`@deepseek-ai/dsh-acp`）在真实编辑器（Zed）连接的瞬间崩溃：第一个 `session/new` 请求返回 `Internal error: cannot get property "agents" without inject`，`session/load` 对 `sessionPersistence` 返回同样的错误。尽管有 178 个绿色单元测试和 100% 行覆盖率，bridge 在生产环境中完全无法工作。两个独立的 bug 隐藏在同一个错误字符串背后，测试套件之所以两个都没捕获，原因也相同：所有测试都通过一条不会触及插件真实加载方式和服务真实解析方式的路径来挂载插件。
+
+## 影响
+
+ACP 服务器无法创建或加载任何一个会话——而这正是编辑器最先调用的两个 RPC。任何将 agent（智能体）接入 Zed 的人都会立即遭遇硬性失败。无数据丢失（崩溃前没有任何内容被持久化）；代价完全是「功能不可用」加上两次定位原因的调试时间。
+
+## 时间线
+
+- bridge（RFC 010）落地时附带完整的单元测试套件（codec、内存传输、基于属性的协议形状测试、失败路径、HMR（热模块替换））、一个需要 key 的真实 API e2e 测试，以及一个无需 key 的 stdout 纯净性 e2e 测试。全部绿色，100% 覆盖率。
+- 真实 Zed 会话在 `session/new` 上立即失败，报错 `cannot get property "agents" without inject`。
+- 调查最初追踪了一个 Cordis「traceable/shadow」理论（看似合理，且该机制确实存在——见 Bug #2），随后在 vendor 的 `reflect.ts` 中对实际 fiber 遍历做了插桩，并运行了真实子进程。trace 显示 throw 发生在 `apply()` 第 179 行、*插件加载时*，位于 ROOT fiber 且没有 shadow——推翻了 shadow 理论对 `session/new` 的解释。
+- 找到根因 #1：一行多余的 `export default apply`。删除后 `session/new` 修复。
+- 删除后暴露了 Bug #2：`session/load` 仍然在 `sessionPersistence` 上抛错——这是一个真正不同的机制（shadow 遍历），通过隔离修复并重新运行真实子进程得到确认。
+
+## 根因 #1——`export default apply` 丢弃了插件的 `inject`（导致 `session/new` 崩溃）
+
+`packages/acp/acp/src/index.ts` 是一个*命名空间插件*：它将 `name`、`inject`、`Config` 和 `apply` 作为独立的命名导出——与仓库中其他所有插件（`invariants`、`llm-deepseek`、`tool-bash`、`tui` 等）形状相同。但它*还*多了一行其他插件都没有的代码：
+
+```ts ignore-check
+export const name = 'acp'
+export const inject = ['agents', 'sessions', 'sessionPersistence']
+export function apply(ctx: Context, config: AcpConfig): void { /* … */ }
+// …
+export default apply // ← the bug
+```
+
+当插件从 `cordis.yml` 加载时，Cordis Loader 通过 `Loader.unwrapExports`（`vendor/loader/src/index.ts`）对导入的模块进行规范化：
+
+```ts ignore-check
+unwrapExports(exports: any) {
+ if (isNullable(exports)) return exports
+ exports = exports.default ?? exports // ← prefers `.default`
+ if (!exports.__esModule) return exports
+ return exports.default ?? exports
+}
+```
+
+存在 default export 时，`exports.default ?? exports` 解析为**裸 `apply` 函数**。裸函数没有 `inject`、没有 `name`、没有 `Config` 属性——这些作为*兄弟*命名导出存在于模块命名空间上，而 unwrap 到 `.default` 把整个命名空间丢弃了。Loader 随后基于空的 `inject` 构建了插件的 fiber。
+
+因此 `apply` 在一个**没有注入任何服务**的 fiber 中运行。第一行 `const agents = ctx.agents` 遍历 fiber 树（ROOT → Include → Loader → ROOT），在所有 fiber 的 store 中都找不到 `agents`，到达根 fiber（`runtime === null`）后抛出 `cannot get property "agents" without inject`。崩溃发生在*加载时*，而非后续的请求处理器中——请求只是恰好触发了加载。
+
+**修复：** 删除 `export default apply`。Loader 随后使用模块命名空间，正确识别 `inject`/`name`/`Config`，`apply` 在一个真正授予了声明服务的 fiber 中运行。
+
+## 根因 #2——可选服务读取通过 traceable shadow 触发 inject 守卫（导致 `session/load` 崩溃）
+
+修复 #1 后，`session/new` 正常工作，但 `session/load` 仍然抛出 `cannot get property "sessionPersistence" without inject`。这个问题*确实*是 Cordis 的 traceable/shadow 机制，值得精确理解。
+
+`session/load` 调用 `agents.resume(...)`，后者委托给 `AgentLoop.resume()`，其中读取了 `this.ctx.sessionPersistence`。`AgentLoop` 的 `static inject` 故意不包含 `sessionPersistence`——注入它会导致非持久化的演示永远挂起，等待一个永远不会加载的后端。该服务由一个独立的兄弟插件/fiber 提供，以机会性方式读取。
+
+Cordis 中的服务访问通过上下文代理（`vendor/cordis/src/reflect.ts`）进行。当通过从外部 fiber 获取的 *traceable 代理*调用服务方法时（此处：bridge fiber 调用 `ctx.agents.resume`，注册表返回 `this.factory`——即 `AgentLoop`——重新包装为绑定到调用方的新 traceable 代理），`createShadowMethod`（`vendor/cordis/src/utils.ts`）将 `this` 重新绑定到一个 *shadow* 对象，其 `ctx` 携带 `[symbols.shadow]` 指向 `AgentLoop` 自身的构造上下文。在 `resume` 内部，`this.ctx.sessionPersistence` 的解析从 shadow 的 fiber 开始遍历：
+
+```ts ignore-check
+// reflect.ts get handler
+let fiber = (ctx[symbols.shadow] as Context ?? ctx).fiber // ← starts at AgentLoop's fiber
+while (true) {
+ const impl = fiber.store?.[prop]
+ if (impl) return getTraceable(ctx, impl.value)
+ if (prop in fiber.inject) { /* inactive-context error */ }
+ if (!fiber.runtime) throw error // ← reached root, throw
+ if (fiber.parent[symbols.isolate][prop] !== key) throw error
+ fiber = fiber.parent.fiber // ← ancestor-only
+}
+```
+
+遍历**仅向祖先方向**进行。`sessionPersistence` 既不在 `AgentLoop` 的 fiber store 中（不在其 `static inject` 中），也不在通往 root 的任何祖先上（它位于一个*兄弟*分支），因此遍历到达根 fiber 后抛错。
+
+为什么内存中的 `AgentLoop` 恢复测试没有捕获这个问题？因为它们从测试代码直接调用 `ctx.agents.resume(...)`——*在任何插件 fiber 之外*。此时 `ctx.fiber.runtime` 为 `null`，代理处理器走了一条提前绕过的路径：
+
+```ts ignore-check
+if (!ctx.fiber.runtime) return ctx.reflect.get(prop, false) // ← direct global-store lookup, no fiber walk
+```
+
+`ctx.reflect.get(name, false)` 是基于 isolate symbol 的全局服务 store 直接查找——完全忽略 fiber 拓扑，能找到服务。因此从顶层测试读取可以成功；而从真实插件 fiber 内部、经由 shadow 到达时则抛错。bridge 恰好是后者。
+
+**修复：** 使用 `ctx.get('sessionPersistence')` 读取可选服务，该方法使用全局 isolate-keyed store 同时保留活跃状态检查。对于插件声明注入集中的服务，直接属性读取仍然适用。
+
+## 为什么所有测试都没有捕获（真正的失败）
+
+两个 bug 共享同一个流程缺口：**没有任何测试通过插件的真实加载路径或真实调用拓扑来驱动它。**
+
+- 内存 harness 通过手动构建插件对象来挂载 bridge：`ctx.plugin({ name, inject, apply })`。这手动提供了 `inject`，因此永远无法复现 Bug #1——`unwrapExports` 只被 *Loader* 调用，`ctx.plugin` 从不调用它。即使 `ctx.plugin(NamespaceImport)` 也无法捕获。
+- 同一个 harness 将所有内容平铺挂载在一个根上下文上，因此从中触达的 `AgentLoop` 恢复要么运行在顶层（`!runtime` 绕过），要么通过一个 origin 仍然解析在 root 上的 shadow——掩盖了 Bug #2 的祖先遍历失败。
+- 唯一的无 key e2e 发送 `initialize` 并检查 stdout 纯净性。`initialize` 从不触达 factory，因此两个 bug 都安然通过。
+- 唯一驱动 `session/new`/`session/load` 的测试需要 key 才能运行，因此 CI（无 key）跳过了它——而本地它之所以「通过」，只是因为一个陈旧的已构建 `lib/`（包含旧代码）恰好满足了模块解析。
+
+100% 行覆盖率始终满足。覆盖率证明代码行*被执行过*；它不能说明功能是否*按交付方式正常工作*。
+
+## 新增的防护措施
+
+- **删除 `export default apply`**（`packages/acp/acp/src/index.ts`）——Bug #1 的修复。
+- **`AgentLoop.resume` 使用 `this.ctx.get('sessionPersistence')`**（`packages/core/agent-loop/src/index.ts`）——Bug #2 的修复，附注释说明 shadow 遍历陷阱。
+- **无需 key 的 `session/new` e2e，通过真实 stdio 运行**（`examples/acp-agent/tests/acp.e2e.ts`）：以子进程方式通过真实 Loader 启动示例，并断言 `session/new` 正常返回。无需 API key 即可在 Bug #1 上大声失败。已验证恢复 `export default apply` 时测试失败。
+- **e2e spawn 中设置 `TSX_TSCONFIG_PATH`**：子进程从临时 cwd 运行，tsx 无法通过向上搜索找到仓库根的 tsconfig `paths` 映射——因此 dsh-* 的 import 静默回退到已构建的 `lib/`。将 tsx 指向仓库 tsconfig 使解析不依赖 cwd，确保测试运行的是*源码*而非可能陈旧的构建产物。
+- **[docs/testing.md](../testing.md) 规则**：「测试真实入口路径」，行覆盖率不等于行为覆盖率——将这一教训编纂为所有未来插件的规则。
+
+## 经验教训
+
+- 命名空间插件与 default export 在 Cordis Loader 下互斥。选择命名空间形式（`name`/`inject`/`Config`/`apply`），不要添加 `export default`——`unwrapExports` 会丢弃命名空间。
+- 对于插件机会性读取但未在 `static inject` 中声明的服务，使用 `ctx.get(name)`，绝不使用 `ctx.<name>`。属性代理通过仅向祖先方向的 fiber 遍历解析，经由外部 shadow 时会失败；`ctx.get(name)` 是拓扑无关的查找（且默认严格——非活跃后端读取为 `undefined`，而非在 teardown 过程中被交出）。
+- 手动构建插件的测试无法验证插件的加载方式。至少一个测试必须端到端地驱动真实的 Loader/export 路径。当核心操作不调用模型时，该测试无需 API key——因此它属于 CI，而非 key 门控之后。
+- 相信 trace，不要相信理论。优雅的 shadow 解释是真实的，但它是*第二个* bug；*第一个*是一行导出错误，在数小时看似合理但实际错误的推理之后，一个 fiber 遍历的 `console.error` 在几分钟内就找到了它。

+# 事故复盘（postmortem） 0002：文件系统快照工具被永久禁用
+
+[English](0002-js-expression-disabled-filesystem-tools.md) | 中文
+
+Status: resolved
+
+## 摘要
+
+ACP（Agent Client Protocol）示例试图通过 `disabled: !!js ...` 有条件地启用文件系统插件，但 Cordis 仅在插件 `config` 内部对 JavaScript 表达式求值。原始的表达式对象为 truthy，因此文件系统栈始终处于禁用状态。快照刷新随后将 `UNKNOWN_TOOL` 结果接受为新的预期输出。修复方案改用显式的文件系统 overlay，并增加了静态配置守卫和快照结果守卫。
+
+## 概述
+
+默认的 ACP 组合有意只启用 bash，因为其沙箱无法约束进程内的文件系统提供方。文件系统快照场景仍然需要 `read`、`write` 和 `edit`，因此这些插件被放在默认的 `cordis.yml` 中，并附带一个 `disabled` 表达式，意图仅在全权限启动和快照模式下启用它们。
+
+Cordis Include 将每个 `!!js` 标量解析为一个表达式对象。Loader 递归地对插件的 `config` 进行插值，但直接消费 `disabled` 等入口元数据。因此每个文件系统入口看到的都是一个 truthy 对象，在所有模式下均保持禁用。
+
+## 影响
+
+七个文件系统场景和一个混合工作区编辑场景调用了注册表中不存在的工具。其结构化会话日志携带 `ToolNotFoundError`（code 为 `UNKNOWN_TOOL`），stdout 渲染出通用的失败工具卡片。快照套件通过了，因为结构化会话日志和 stdout 渲染出的通用失败工具卡片均与刷新后的 fixture（测试前置数据）匹配；它证明的是回归的确定性回放，而非文件系统行为的正确性。
+
+实际运行的受限默认模式并未获得意外的文件系统访问权限。一个简单的插值修复反而会制造该风险：权限预设在运行时更新 bash 沙箱和审批状态，但无法挂载、卸载或约束文件系统栈。
+
+## 时间线
+
+- PR（Pull Request） #261 整合了 ACP 组合并刷新了文件系统快照，同时引入了条件式文件系统入口。
+- 所有单元测试、覆盖率、快照、文档、构建和 hygiene 检查均通过。
+- 对刷新后的文件系统预期输出的评审发现了通用的失败卡片和结构化的 `UNKNOWN_TOOL` 结果。
+- 一次真实的 Loader 启动确认：每个 `disabled` 值仍为表达式对象，每个文件系统 fiber 均未创建。
+
+## 根因
+
+实现时假设 `!!js` 适用于整个 Loader 入口。其实际边界更窄：`Entry._resolveConfig()` 仅对 `entry.options.config` 进行插值；`Entry.disabled` 直接测试 `entry.options.disabled`，不经过插值。YAML 标签在语法上合法，因此加载过程不产生任何诊断信息。
+
+快照框架将任何确定性的 transcript（文本记录）视为有效行为。Header pin 验证了组合后的工具 schema，但文件系统场景共享来自默认组合的 pin，因此未独立证明其所需工具已注册。刷新在任何语义断言拒绝缺失工具之前，就已重写了预期的 stdout 和会话日志。
+
+## 已添加的防护措施
+
+- 文件系统场景启动 `fs.cordis.yml`：一个显式的固定全权限 overlay，配有对应的回放配置和独立的 request-header 类。
+- [`AGENTS.md`](../../AGENTS.md) 与 [Cordis 入门](../cordis-primer.md#loader-configuration)明确说明 `!!js` 仅在插件 `config` 内有效，条件式组合应使用 overlay。
+- `verify-cordis-config` 解析仓库中的 Cordis YAML，拒绝 Loader 入口元数据中的表达式节点（包括 include patch 和插入的入口）。
+- `dsh-acp-snapshot` 在新鲜运行和已提交的会话 fixture 中拒绝结构化的 `UNKNOWN_TOOL` 结果，防止其被提交为预期输出。
+
+## 教训
+
+- 语法上被接受的配置值不一定在该位置被求值；应记录并验证插值边界。
+- 快照刷新是 fixture 的生产过程，不是正确性审查。诸如已注册工具缺失这类语义上不可能的结果，需要独立于预期输出的断言。
+- 权限控制只应描述其实际管辖的能力。组合时的文件系统访问无法安全地跟随运行时的 bash-only 预设。

# Post-mortems

Incident write-ups: a bug reached a place it shouldn't have (a real user, a merged PR, a release), and the interesting part is *why our process let it through*, not just the one-line fix.
A post-mortem is NOT an [Agent Note](../../.agents/notes/README.md) (which records a deliberate design decision and its rejected alternatives, or proposes future work). It is a backward-looking record of a failure: what broke, the mechanism, why every safety net missed it, and the concrete guardrails added so the same class of bug fails loudly next time.

# Testing policy
+English | [中文](testing.zh.md)
+
How this repo tests, tier by tier, and the rules that keep a green suite meaningful. Commands live in root [AGENTS.md](../AGENTS.md); linked Agent Notes carry the rationale.
## Tiers
-- **Unit** (`pnpm run test`): vitest over `packages|examples/*/tests/**/*.spec.ts`, colocated with what they test. Every registry gets an HMR-safety test (dispose the contributing fiber, assert cleanup). Prefer edge cases, error paths, event ordering, concurrency races, and permanent contract regressions (see `packages/core/agent-loop/tests/contract-regressions.spec.ts`).
+- **Unit** (`pnpm run test`): vitest over package and example specs under their `tests/**` directories plus repository script specs under `scripts/**/*.spec.ts`; tests stay with the code area they exercise. Every registry gets an HMR-safety test (dispose the contributing fiber, assert cleanup). Prefer edge cases, error paths, event ordering, concurrency races, and permanent contract regressions (see `packages/core/agent-loop/tests/contract-regressions.spec.ts`).
- **Coverage gate** (`pnpm run test:coverage`): the gating run, per-file 100% on `packages/*/*/src`. An uncovered line is often dead code the gate is correctly flagging for deletion, not a missing test to bolt on. Line coverage is necessary, never sufficient — it proves lines ran, not that the feature works as shipped.
- **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
-- **Snapshot** (`pnpm run test:snapshot`): transport-specific keyless expected outputs cover external presentation. ACP suites boot the real example subprocess, replay a recorded session, and diff normalized JSON-RPC plus the re-persisted log ([ACP snapshot Agent Note](../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md)); the headless suite independently pins `stream-json` through its real one-shot subprocess. TUI completed journeys replay recorded primary/child JSONL through the real agent loop and tools before projecting ANSI into semantic terminal-state expected outputs; package-local snapshots retain transient renderer states, and a real PTY conversation covers the process boundary ([TUI snapshot Agent Note](../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md)). Use `pnpm run test:snapshot:record` when a model transcript must change and `pnpm run test:snapshot:refresh` when committed replay input remains correct; review every JSONL and expected-output diff. System-prompt/tool-schema content is pinned by one ACP scenario (`text-turn`) and tokenized in every other fixture, so a prompt or schema edit churns one committed line ([pinned-header Agent Note](../.agents/notes/implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).
+- **Snapshot** (`pnpm run test:snapshot`): keyless expected outputs cover external behavior — transport contracts and presentation, while persisted logs pin assembled backend behavior. ACP boots the real automation-server example, replays a recorded session, and diffs normalized JSON-RPC plus the re-persisted log ([ACP snapshot Agent Note](../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md)); headless pins `stream-json` through its real one-shot process. TUI journeys replay primary/child JSONL through the real loop and tools, then project ANSI into semantic terminal-state outputs; package snapshots retain transient states and a real PTY covers the process boundary ([TUI snapshot Agent Note](../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md)). Use `pnpm run test:snapshot:record` when a model transcript changes and `pnpm run test:snapshot:refresh` when replay input remains valid; review every JSONL and expected-output diff. One ACP scenario (`text-turn`) pins full system-prompt/tool-schema content; other fixtures tokenize it so an edit churns one line ([pinned-header Agent Note](../.agents/notes/implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).
+- **Web browser snapshot** (gate-exempt `pnpm run test:web`): real chromium over the in-process web composition replays recorded fixtures against conversation aria goldens (`apps/web/tests/snapshots/`); record/refresh semantics and the deferred CI browser decision: [web e2e lane Agent Note](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md).
## The with-key policy: inference is cheap here
-We are DeepSeek — do not ration real-API tests. A no-key test proves plumbing; only a with-key run proves the agent works against a real model. Write many: file-writing prompts, multi-turn conversations, tool use, cancellation mid-stream. Highest-value are **smoke tests** that boot the real example, send one real prompt, and check the world — they catch the "green unit tests, broken product" class that mocks structurally cannot ([postmortem 0001](postmortem/0001-acp-default-export-drops-inject.md)). The self-skip exists only so secretless CI and keyless contributors aren't blocked; it is not a cost signal. Every example ships both a keyless smoke and a with-key smoke ([examples/AGENTS.md](../examples/AGENTS.md)).

## Prefer the real implementation over a mock
-Mock only the genuinely expensive or non-deterministic boundary (the LLM adapter, the network, the clock); keep everything downstream real. A hand-rolled stand-in proves the bridge moves bytes, not that the shipping tool behaves as asserted — the two drift while the test stays green. Example: bridge tool-call tests run the scripted mock MODEL but the real tool + real executor (`makeBridgeHarness({ withBash: true })` plugs `dsh-bash-local` + `dsh-tool-bash` and runs an actual `echo`).

+- **覆盖率门禁**（`pnpm run test:coverage`）：门禁级运行，对 `packages/*/*/src` 按文件 100% 覆盖。未覆盖的行往往是门禁正确标记出的死代码（应删除），而非需要补写的测试。行覆盖率是必要条件，但永远不是充分条件：它证明行被执行过，不证明功能按交付预期工作。
+- **真实 API e2e**（`pnpm run test:e2e`）：带密钥测试调用真实提供方 API，包括 DeepSeek 模型以及各提供方特有的冒烟测试；这些测试各自由自己的密钥控制（`EXA_API_KEY`、`PERPLEXITY_API_KEY` 等），缺少密钥时套件会自动跳过，使 keyless CI 保持绿色（[真实 API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)）。
+- **快照**（`pnpm run test:snapshot`）：无密钥预期输出覆盖对外行为（传输契约与呈现），持久化日志则固定组装后的后端行为。ACP 启动真实的自动化服务器示例、回放录制会话，并对归一化 JSON-RPC 与重新持久化的日志执行 diff（[ACP 快照 Agent Note](../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md)）；headless 通过真实单次运行进程固定 `stream-json`。TUI 旅程通过真实循环与工具回放主会话与子会话 JSONL，再将 ANSI 投影为语义化终端状态输出；包级快照保留瞬态状态，真实 PTY 覆盖进程边界（[TUI 快照 Agent Note](../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md)）。当模型 transcript（文本记录）发生变化时使用 `pnpm run test:snapshot:record`，回放输入仍然有效时使用 `pnpm run test:snapshot:refresh`；请审查每一处 JSONL 与预期输出差异。一个 ACP 场景（`text-turn`）固定完整的系统提示词与工具 schema 内容；其他 fixture（测试前置数据）将其 token 化，因此修改只会扰动一行（[pinned-header Agent Note](../.agents/notes/implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)）。
+- **Web 浏览器快照**（豁免门禁的 `pnpm run test:web`）：真实 chromium 在进程内 web 组装之上回放已录制 fixture，与会话区 aria 预期输出比对（`apps/web/tests/snapshots/`）；`DSH_SNAPSHOT=record`/`refresh` 的语义与暂缓的 CI 浏览器决策见 [web e2e 车道 Agent Note](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md)。
+
+## 带密钥策略：推理在这里很便宜
+
+我们是 DeepSeek，不要吝惜真实 API 测试。无密钥测试只能证明底层通路；只有带密钥运行才能证明 agent（智能体）能对接真实模型正常工作。覆盖文件写入提示词、包含多个轮次的对话、工具使用和流中取消。价值最高的是**冒烟测试**：启动真实示例、发送一条提示词，并检查外部世界；它们能捕获「单元测试全绿、产品却坏了」这一类 mock 无法发现的问题（[事故复盘 0001](postmortem/0001-acp-default-export-drops-inject.md)）。自动跳过让无密钥 CI 和无密钥贡献者不受阻塞；它不是成本信号。每个示例都提供无密钥和带密钥冒烟测试（[examples/AGENTS.md](../examples/AGENTS.md)）。
+
+## 优先使用真实实现而非 mock
+
+只 mock 开销高或不确定的边界（LLM（大语言模型）适配器、网络、时钟）；下游一切保持真实。手写替身只能证明桥接层在搬运字节，不能证明交付的工具行为符合断言。桥接工具调用测试将脚本化 mock 模型与真实工具和执行器配合使用：`makeBridgeHarness({ withBash: true })` 接入 `dsh-bash-local` 与 `dsh-tool-bash`，然后运行 `echo`。
+
+恢复测试按步骤区分分片前与分片后的失败，并证明失败分片不会派生出消息或工具副作用。覆盖耗尽、取消、策略组合、持久化、状态、协议计数、会关闭传输的空闲超时，以及交付的 Loader 组合。
+
+## 验证外部世界，而非自我报告
+
+e2e 断言应重新运行命令或从外部重新读取文件；对 agent 自身输出做关键词探测会让作弊的 agent 通过。断言未修改的文件逐字节一致。e2e 测试自行管理资源：在测试中创建 harness，在 `afterEach` 中 dispose（即使失败/重试/超时也要释放）；共享 fixture 放在普通的 `tests/harness.ts` 中，绝不放在另一个 `*.e2e.ts` 中（导入一个 spec 会重新注册其 `describe`，导致真实 API 调用重复执行）。
+
+## 测试真实入口路径
+
+- 产品可见的插件必须有一个非单元的真实组合测试。手动构建的 `ctx.plugin(...)` 套件不够：通过 Loader 和 app/process 启动仅用于测试的 `cordis.yml`，只 mock 外部/不确定边界，断言模型可见的请求/日志、持久状态或用户可见输出。不要把 opt-in 选项混入交付默认值。
+- 一个守卫只有在回归真的能让它失败时才有效。对于没有 `inject` 的插件（bundle/组合插件），Loader 冒烟测试在导出形状损坏时仍然绿着——需要添加显式的 `expect('default' in mod).toBe(false)` 加 `unwrapExports` 往返断言，并证明它有效：引入回归、观察变红、回退。
+- 「真实入口路径」指已发布的产物：包的 `bin` 所运行的是构建后的 `lib/bin.js`，并由普通 `node` 执行，从而暴露 tsx 会掩盖的失败（等待稳定时的竞态、模块解析、被吞掉的加载失败）。同样的规则适用于非 index 运行时入口（worker-thread 的同级文件 `lib/worker.cjs`），也适用于多个 bundle 共享的单例模块（`packages/ui/jsonrpc/tests/built-scope-carrier.e2e.ts`）。保持构建产物冒烟测试绿色（`packages/ui/*/tests/built-bin.e2e.ts`、`packages/code-runtime/code-runtime-worker/tests/built-lib.e2e.ts`），并断言真正缺失的配置以非零状态退出。
+
+## 测试解析：仅限源码
+
+- 每个 vitest 配置都将 vite-tsconfig-paths 指向 `tsconfig.base.json`；工作区包的裸导入解析到 `src`（[布局](development.md#typescript-project-layout)），绝不会经由包的 `exports` 解析到构建后的 `lib/`，因为其中的陈旧产物会加载第二份模块单例。构建产物只在显式指定时使用：以 `lib` 模式运行的子进程，以及下文的构建产物冒烟测试。
+
+## 测试子进程启动模式
+
+- CI 与已有构建产物的测试通道通过共享双模式启动器，从构建后的 `lib/` 运行每个示例或 Cordis 配置子进程。不要为这些子进程手写 `--import tsx`。
+- 不加载 Cordis 的协议与操作系统 fixture 直接通过 Node 运行使用可擦除语法的 `.ts` 文件，不经过 tsx 或根路径映射。
+- 只有测试对象本身是源码路径解析时，才可以选择 `src`；在测试中写明这一契约。
+
+## 何时需要快照测试
+
+每项非平凡的模型可见、协议可见或人类可见变更，都必须在同一 PR 中，通过可运行示例所属的快照套件添加或更新无密钥场景。包测试、e2e 断言、mock 与仅测试组合、PR 理由都不能取代组装后的 transcript；必要时应扩展 harness。ACP 自动化场景使用 `examples/<name>/tests/snapshots/`，即基于 [`dsh-acp-snapshot`](../packages/support/acp-snapshot/README.md) 套件工厂的场景表（`examples/acp-agent` 为主套件）；`examples/headless-agent` 拥有 `stream-json` 快照与回放 fixture。已完成的交互式终端旅程使用 `examples/tui-agent/tests/snapshots/` 下由 JSONL 驱动的场景；瞬态呈现使用包内语义矩阵，输入、Loader 选择或终端清理发生变化时还要添加 PTY 用例。新的能力 seam、生命周期形态或 transcript 呈现接口在计划阶段就要列出每个覆盖层级，并在实现前验证 harness 能够表达它们。

# acp-agent example
-The DeepSeek Harness SDK agent demo exposed as an **Agent Client Protocol (ACP)** server over JSON-RPC stdio — drive it from Zed or any other ACP client.
+Automation-oriented [Agent Client Protocol](https://agentclientprotocol.com) server over JSON-RPC stdio. It is intended for parent agents, subagent providers, and other programmatic clients, not as the product UI.
```sh
-pnpm run demo:acp # needs DEEPSEEK_API_KEY (repo-root .env or env)
-pnpm run demo:code-mode acp # the same server in Code Mode: one wire tool, run_code
+pnpm run demo:acp # needs DEEPSEEK_API_KEY (repo-root .env or env)
+pnpm run demo:code-mode acp # same protocol with the Code Mode tool transport
```
-The leaf config loads the ACP app, DeepSeek adapter, plan mode, sandboxed bash, the sandboxed filesystem stack, approval and permission services, model-facing tools, and repeat guard. The app bundles the agent spine, JSONL persistence, and bridge, creates agents on `session/new`, and keeps stdout logger-free. [`fs.cordis.yml`](fs.cordis.yml) adds local tool-result spill storage for its dedicated scenarios; [`code-mode.cordis.yml`](code-mode.cordis.yml) adds `run_code` and its generated TypeScript SDK. See [Code Mode](../../packages/core/tools/README.md#code-mode).
+The leaf loads the ACP app, DeepSeek adapter, sandboxed bash and filesystem stacks, one-shot approval policy, compaction, subagents, workflows, hooks, a derived session-query index, and repeat guard. The app creates one fresh agent per `session/new`, persists sessions to JSONL, and keeps stdout protocol-pure. [`session-query.cordis.yml`](session-query.cordis.yml) explicitly opts into the workspace-authorized query tools and generic timeout/spill policies for their dedicated snapshot; [`fs.cordis.yml`](fs.cordis.yml) adds spill storage for filesystem scenarios, while [`code-mode.cordis.yml`](code-mode.cordis.yml) adds `run_code` and its generated TypeScript SDK.
-## stdout is the protocol
+## Protocol channel
-This example loads **no stdout logger** — `stdout` carries the JSON-RPC frames, and any other write corrupts them. `@deepseek-ai/dsh-acp-demo` includes no logger entry, so this leaf has none to get wrong by default; do not add one (use a stderr exporter if you need logs).
+Stdout carries only newline-delimited ACP JSON-RPC. `@deepseek-ai/dsh-acp-demo` installs no stdout logger; leaf additions must use stderr for diagnostics.
-## Zed configuration
+The automation contract — supported methods, baseline prompt content, committed-text output, and the intentionally absent UI surfaces — lives in [`@deepseek-ai/dsh-acp`](../../packages/acp/acp/README.md).
-Add to your Zed `settings.json` under `agent_servers`:
+## Session workspaces and permissions
-```json
-{
- "agent_servers": {
- "DeepSeek Harness": {
- "command": "pnpm",
- "args": ["--dir", "/path/to/deepseek-harness", "run", "demo:acp"],
- "env": { "DEEPSEEK_API_KEY": "sk-…" }
- }
- }
-}
-```
+Each `session/new` supplies an absolute `cwd`. Sandboxed bash and filesystem mutations resolve `workspace-write` against that session cwd, so concurrent sessions can use separate project roots; platform temporary roots remain shared writable scratch space ([sandbox contract](../../packages/sandbox/sandbox/README.md)). `DSH_PERMISSION_MODE` selects `workspace-write` or `danger-full-access` for deployment and tests.
-The editor sets each session's `cwd` to the project it opens. That directory is both bash's default workdir and the session's primary `workspace-write` boundary: every bash or filesystem mutation carries one policy resolved from the calling session, so a single server process may serve concurrent projects. Projects outside the platform temporary areas do not grant either session writes into the other; `/tmp` and `os.tmpdir()` remain shared writable scratch roots under `workspace-write`, so projects placed there are not mutually isolated ([writable-root contract](../../packages/sandbox/sandbox/README.md)). The configured `workspaceRoot: process.cwd()` remains the fallback for calls without a session cwd. The filesystem tools ride the same policy through [`@deepseek-ai/dsh-fs-sandbox`](../../packages/fs/fs-sandbox/), so `read`/`write`/`edit` are available under every mode and confined to the same policy.
+Under `workspace-write`, a model retry requesting wider sandbox access triggers `session/request_permission` with `allow_once` and `reject_once`. The client decides programmatically; dismissal or an unavailable answer fails closed. The selected outcome applies only to that retry and is recorded through the normal tool-result/audit path. The server never exposes a permission picker or persists client policy.
-## Plan mode
+## Snapshot tests
-The same `demo:acp` server composes [`@deepseek-ai/dsh-plan-mode`](../../packages/plan/plan-mode/), so a capable client advertises `default` and `plan` in its mode picker. ACP owns those protocol ids and projects them onto the plugin's boolean plan state. This composition owns the complete plan instructions in [`cordis.yml`](cordis.yml): remain in plan mode, inspect before asking, avoid mutations, resolve discoverable repository facts, and submit a decision-complete plan through `exit_plan_mode`. Those are the instrumental behaviors shared by the local Codex and Claude Code references; product-specific plan files, phase machinery, and protocol tags stay out of the plugin contract.
+This example owns the ACP snapshot suite. It boots the real automation server, replays committed model streams through `dsh-llm-replay`, and compares both normalized protocol output and re-persisted session logs. Recording uses the real model; refresh reuses committed replay input. Overrides cover throw/hang behavior, and optional `workspace/` fixtures seed world-state checks.
-Plan mode adds only that configured guidance section. Every tool, including `exit_plan_mode`, keeps the same schema while plan mode is inactive or active; the exit tool describes itself as plan-only and rejects if called while inactive. Stable native schemas and Code Mode SDK bindings avoid tool-catalog churn at the transition. `ask_user_question` carries blocking user-owned choices through ACP elicitation, while `exit_plan_mode` renders the exact logged plan for approval and returns keep-planning feedback to the model. The mode picker and permission select remain independent: switching plan state never changes sandbox or approval state, and deployments that need a hard read-only planning floor configure that policy separately. The [plan-mode Agent Note](../../.agents/notes/implemented/feature/2026-07-07-plan-mode.md) owns the state and review contract.
-
-## Snapshot tests (record-once / replay-deterministic)
-
-This example hosts the ACP snapshot suite, including the picker advertisement and both plan-review branches. It replays through `dsh-llm-replay`, which reconstructs model streams from `assistant/chunk` events in each scenario's session JSONL. Recording runs the real ACP agent and harvests its logs; refresh keeps the committed transcript as mock input and rewrites current replay outputs. `replay.override.json` covers throw and hang cases that chunks cannot express, and an optional `workspace/` seeds files. The [snapshot Agent Note](../../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md) owns the ACP harness design.
-
-## Permissions and sandboxing
-
-The default tree composes [`@deepseek-ai/dsh-sandbox-local`](../../packages/sandbox/sandbox-local/), [`@deepseek-ai/dsh-sandbox-policy`](../../packages/sandbox/sandbox-policy/), [`@deepseek-ai/dsh-bash-sandbox`](../../packages/bash/bash-sandbox/), [`@deepseek-ai/dsh-fs-sandbox`](../../packages/fs/fs-sandbox/), [`@deepseek-ai/dsh-user-approval`](../../packages/ui/user-approval/), and [`@deepseek-ai/dsh-permission`](../../packages/ui/permission/). Bash and the `read`/`write`/`edit` tools start in `workspace-write`; a denied operation returns a structured marker, and a retry with `sandbox_permissions` plus `justification` becomes a one-shot `session/request_permission` prompt in the editor. "Allow once" runs exactly that retry under the wider mode ([sandbox Agent Note § Escalation](../../.agents/notes/implemented/feature/2026-07-06-sandbox.md)).
-
-- **One session config option is live**: a capable client shows one `Permissions` select. `workspace-write` means workspace-confined bash plus `ask`; `danger-full-access` means unconfined bash plus `never`. Switching writes one `permission/preset` event through to the sandbox-mode and approval-policy events, and `session/load` reports the resumed value.
-- **Every approval is one-shot**: the choices are `Allow once` and `Reject`; a dismissal, rejection, missing editor, or unavailable runner fails closed.
-- **The boundary spans bash and the filesystem tools per session**: bash confines through the OS runner and the `read`/`write`/`edit` tools through an in-process path fence ([`dsh-fs-sandbox`](../../packages/fs/fs-sandbox/)); both receive the calling session's cwd as `workspaceRoot`.
-
-`tests/escalation.e2e.ts` boots this default tree keyless, drives the permission select, and—with a key and usable runner—proves both approval outcomes against the filesystem. The agent-spine e2e independently boots one context with two home-directory project sessions and world-verifies concurrent own-root success plus sibling-root denial through both shipped tool families. The keyless `session-sandbox-root` ACP snapshot places its generated project under the user home while an overlay points the deployment fallback at `/tmp`; its successful `workspace-write` call proves the assembled app used the session cwd. Most snapshots start at `danger-full-access` so bash fixtures remain runner-independent. No fixture pins real runner denial text because its dialect is platform-specific.
-
-## MVP limitations
-
-The bridge supports N concurrent sessions per connection, each with its own `cwd` (RFC 011). Prompts support ACP's baseline `text` and `resource_link` blocks only; `additionalDirectories` and `mcpServers` are rejected. See [`packages/ui/acp/README.md`](../../packages/ui/acp/README.md) for the full contract.
+Most scenarios pin backend behavior rather than ACP-specific behavior; the [automation-only ACP decision](../../.agents/notes/implemented/simplification/2026-07-23-acp-automation-only-protocol.md#snapshot-boundary) owns why that coverage remains transport-coupled.

- You are in plan mode. Stay in plan mode until exit_plan_mode succeeds or the user switches the session mode. Imperative language to implement changes means plan the implementation, not execute it. A user's conversational agreement — including an answer confirming something you asked — approves nothing and does not end plan mode; fold the confirmed decision into the plan and submit it through exit_plan_mode.
-
- Explore first. Use non-mutating reads, searches, static analysis, and checks to ground the plan in the actual repository. Do not edit or write files, change configuration, run formatters or code generation that rewrites tracked files, commit, or otherwise carry out the plan. Prefer existing functions and patterns over new machinery.
-
- The tool catalog stays the same across modes for request-cache stability. These plan-mode rules override any later tool description or guidance that suggests using mutation tools; those tools remain listed only to keep the request shape stable. Do not use todo_write to track this planning phase: it tracks implementation after an approved plan, while the plan itself belongs in exit_plan_mode.
-
- Resolve discoverable facts by inspection. Use ask_user_question only for user-owned choices or material ambiguity that inspection cannot answer. Do not ask the user where code lives or how current behavior works when you can find out.
-
- Make the plan decision-complete: state the goal and success criteria; group implementation changes by subsystem; identify public API, schema, and data-flow changes; cover edge cases, failure modes, tests, acceptance criteria, and explicit assumptions. Keep it concise enough to review but detailed enough that another engineer can implement it without making design decisions.
-
- When ready, call exit_plan_mode with the complete plan markdown, starting with a # title. Make exit_plan_mode the only and final tool call in that assistant response: it presents the plan for approval, and implementation begins only in a later step after approval. Do not paste the final plan as a plain reply or ask "should I proceed?" through prose or ask_user_question. If review rejects it, incorporate the feedback and present again. If the review channel is unavailable or aborted, stay in plan mode and ask the user to switch modes manually; do not proceed with implementation.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later. */

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

/** Execute a bash command (`bash -c`) and return its stdout/stderr. Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later. */

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later. */

+You are an AI agent powered by the DeepSeek Harness SDK.
+
+You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
+
+Verify your work by running the code or tests. Keep answers brief and factual.
+
+
+Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
+
+Use the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.
+
+Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.
+
+Check the [exit code: N] marker on every bash result; investigate failures before moving on.
+
+Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
+
+Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
+
+<!-- dsh-user-approval-policy:ask -->
+
+Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
+
+Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true.

You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.

Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Keep AT MOST ONE todo `in_progress` at a time; while work remains, exactly one active task should be `in_progress`. Mark a todo `completed` the moment it is done (do not batch completions), and allow no `in_progress` item only once all work is complete. Skip the list for trivial single-step tasks.

- "description": "Run a JavaScript workflow script that orchestrates subagents at scale. Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes.",

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

- "description": "Run a JavaScript workflow script that orchestrates subagents at scale. Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes.",

-You are an AI agent powered by the DeepSeek Harness SDK.
-
-You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
-
-Verify your work by running the code or tests. Keep answers brief and factual.
-
-
-You are in plan mode. Stay in plan mode until exit_plan_mode succeeds or the user switches the session mode. Imperative language to implement changes means plan the implementation, not execute it. A user's conversational agreement — including an answer confirming something you asked — approves nothing and does not end plan mode; fold the confirmed decision into the plan and submit it through exit_plan_mode.
-
-Explore first. Use non-mutating reads, searches, static analysis, and checks to ground the plan in the actual repository. Do not edit or write files, change configuration, run formatters or code generation that rewrites tracked files, commit, or otherwise carry out the plan. Prefer existing functions and patterns over new machinery.
-
-The tool catalog stays the same across modes for request-cache stability. These plan-mode rules override any later tool description or guidance that suggests using mutation tools; those tools remain listed only to keep the request shape stable. Do not use todo_write to track this planning phase: it tracks implementation after an approved plan, while the plan itself belongs in exit_plan_mode.
-
-Resolve discoverable facts by inspection. Use ask_user_question only for user-owned choices or material ambiguity that inspection cannot answer. Do not ask the user where code lives or how current behavior works when you can find out.
-
-Make the plan decision-complete: state the goal and success criteria; group implementation changes by subsystem; identify public API, schema, and data-flow changes; cover edge cases, failure modes, tests, acceptance criteria, and explicit assumptions. Keep it concise enough to review but detailed enough that another engineer can implement it without making design decisions.
-
-When ready, call exit_plan_mode with the complete plan markdown, starting with a # title. Make exit_plan_mode the only and final tool call in that assistant response: it presents the plan for approval, and implementation begins only in a later step after approval. Do not paste the final plan as a plain reply or ask "should I proceed?" through prose or ask_user_question. If review rejects it, incorporate the feedback and present again. If the review channel is unavailable or aborted, stay in plan mode and ask the user to switch modes manually; do not proceed with implementation.
-
-
-Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
-
-Use the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.
-
-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.
-
-Check the [exit code: N] marker on every bash result; investigate failures before moving on.
-
-Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
-
-Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
-
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-<!-- dsh-user-approval-policy:never -->
-
-Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

-Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

-The TUI prints this exact command on exit and lists it under `/resume`, so resuming is copy-paste. The flag sets `RESUME_SESSION_ID`, wired through `cordis.yml` (`resumeSessionId: !!js process.env.RESUME_SESSION_ID`); the env var still works directly for the uninstalled demo (`RESUME_SESSION_ID=<prior-session-id> pnpm run demo:tui`), and with neither set the agent starts a new session. A missing or unreadable id starts no agent and emits `agent-loop/config-start-failed`: the TUI prints the failure and exits nonzero.
+`/resume` opens a searchable keyboard selector with titles, activity, last-turn results, model route, durable goal phase, and live/persisted state. The installed `dsh` host flushes and disposes the current app, then replaces the process with `dsh --resume <id>`. The TUI still prints that command on exit and shows it when a custom host cannot hand off. `dsh --resume <id>` provides the id on the boot context, which `cordis.yml` reads (`resumeSessionId: !!js "typeof resumeSessionId === 'string' ? resumeSessionId : undefined"`); with no flag the agent starts a new session. A missing or unreadable id starts no agent and emits `agent-loop/config-start-failed`: the TUI prints the failure and exits nonzero. The selector has no cross-process session lock, so deployments with concurrent hosts must coordinate session ownership separately.

+# acp/ — Agent Client Protocol automation
+
+The ACP group exposes harness agents to programmatic clients. It is an interoperability transport, not a presentation or human-interaction layer.
+
+| Package | Role |
+|---|---|
+| [`acp/`](acp/README.md) | Automation-only ACP server: fresh text sessions, committed assistant output, machine permission policy, cancellation, and connection-owned teardown. |
+
+The matching out-of-process subagent client remains in [`subagent/subagent-acp`](../subagent/subagent-acp/README.md) because it implements the subagent provider interface; arbitrary ACP clients may drive the same server contract.

+# @deepseek-ai/dsh-acp
+
+Automation-only [Agent Client Protocol](https://agentclientprotocol.com) server over JSON-RPC stdio. Programmatic clients create fresh harness agents, send text prompts, collect committed assistant text, resolve one-shot permission requests by policy, and cancel work. The primary in-repository client is [`dsh-subagent-acp`](../../subagent/subagent-acp/README.md).
+
+This package is a transport adapter, not a UI integration or a capability seam. It does not expose editor navigation, transcript replay, commands, modes, configuration pickers, elicitation, reasoning, plans, titles, or tool presentation. Interactive rendering and human questions belong to the web and TUI modules.
+
+## Plugin
+
+`apply(ctx, config)` opens an `AgentSideConnection` on stdin/stdout and drives `ctx.agents`. Stdout is reserved for protocol frames.
+
+| Config | Default | Meaning |
+|---|---|---|
+| `provider` | — | Initial provider route for every created agent. |
+| `model` | — | Initial model for every created agent. |
+
+Both fields are optional so another agent/request listener may supply the target. The runnable ACP composition requires both.
+
+## Protocol contract
+
+| Method | Behavior |
+|---|---|
+| `initialize` | Negotiates the supported version and advertises baseline-only prompts (no image, audio, or embedded-context capability). No session, editor, terminal, filesystem, or MCP capability is advertised. |
+| `authenticate` | No-op because the server advertises no authentication methods. |
+| `session/new` | Creates a fresh agent with an absolute primary `cwd`; empty `additionalDirectories` and `mcpServers` are accepted, non-empty values reject. |
+| `session/prompt` | Concatenates text blocks, renders baseline resource links as bracketed textual references, rejects empty or beyond-baseline input, permits one in-flight request per session, and settles from that request's owning durable `turn/end`. |
+| `session/cancel` | Cancels only the addressed agent and settles its pending prompt as `cancelled`; unknown ids are no-ops. |
+| `session/update` | Emits one `agent_message_chunk` per non-empty text block in a committed `assistant/message`. Raw deltas and non-message events are omitted. |
+| `session/request_permission` | Offers one-shot allow/reject choices for bridge-owned approval requests carrying a tool call id. Clients may answer automatically. |
+
+One connection may own several sessions. The bridge keys records by branded session id and checks exact agent identity before routing events or permission requests. Each session has an independent prompt slot, workspace, cancellation path, and disposer.
+
+Committed-message output intentionally trades token-by-token latency for a clean automation result. Uncommitted provider chunks and retry attempts cannot leak partial text; reasoning and tool activity remain in the session log for observability through other interfaces.
+
+## Lifecycle
+
+Client disconnect and Cordis disposal share one memoized teardown. The bridge first rejects new sessions and prompts, settles pending prompts, then disposes all owned agent handles in parallel and awaits their loop/session cleanup. An ACP-only plugin reload therefore leaves no orphan agent.
+
+## Running
+
+`pnpm --dir /path/to/deepseek-harness run demo:acp` boots the repository's automation server composition. A parent harness can spawn it through [`@deepseek-ai/dsh-subagent-acp`](../../subagent/subagent-acp/README.md); other ACP clients need only the core methods above.
+
+## Model Experience
+
+### Prompt text
+
+#### What the model sees
+
+`session/prompt` text blocks are concatenated verbatim into one user message; a baseline resource link appears in that message as a bracketed `[resource_link name=… uri=…]` reference the model may open with its own tools. Protocol metadata, client capabilities, permission choices, and session ids never enter the model request.
+
+#### Token effect
+
+Prompt tokens are data-dependent and remain in that session's history until compaction. Concurrent ACP sessions retain independent contexts.
+
+#### KV Cache effect
+
+Append-only; the new user message follows the reusable request prefix and does not invalidate prior cache entries.
+
+### Permission decisions
+
+#### What the model sees
+
+Nothing directly. The owning tool records its allowed, rejected, cancelled, or unavailable outcome through the normal tool-result path.
+
+#### Token effect
+
+Only the owning tool result contributes tokens.
+
+#### KV Cache effect
+
+Append-only through the owning tool result.
+
+## Known Limitations and Deferred Work
+
+- **Fresh sessions only** — load, list, resume, delete, and fork are unsupported.
+- **Baseline prompts and one workspace only** — images, audio, embedded resources, non-empty additional directories, and MCP servers reject; resource links flatten to textual references rather than fetched content.
+- **Committed answers only** — live progress, reasoning, tool activity, plans, titles, and usage stay off the wire.
+- **Connection-owned lifetime** — one connection releases all of its sessions; per-session close is not implemented.

2. **children = declaration + authorization**: the slots your component renders are exactly the keys of your register call's `children` object (spec values: `kind`/`scope`). Rendering a slot you didn't declare, or declaring one someone else declared, fails at load — do not work around it; the conflict is the design speaking. Slot names mirror the composition path: `<domain>.<entry>.<hole>` (e.g. `'conversation.chat.toolview'`).

5. **Live data has exactly three channels**: parent knows it → owner props at the renderSlot site; only the component knows it → local state; shared across entries or survives remounts → a store declared at register. Derived data is a pure function over framework-hook data (`useMemo`), never its own subscription.
6. **Stores: read `props.useStore`, write `props.actions.*`** — the declared actions are the complete mutation surface. Write the store as an exported `createXXXStore()` factory (module-level handles are forbidden — de-facto singletons); share by passing one handle to several registers inside `apply`. Production code never calls the factory or `.create()` outside `apply`; tests do (that is the sanctioned zero-machinery path).
7. **inject returns plain data and callbacks** from the apply closure's own ctx — no hooks, no ReactNode producers, no whole-service objects. Its capability boundary is the plugin's declared `inject` topology; there is no wider ctx to reach for.

+## New plugin package checklist
+
+Bringing up a new `packages/client/<name>` plugin package (ui-workspace is the latest walked example; ui-sidebar/ui-question are good skeletons to copy):
+
+1. **Package skeleton**: `package.json` (`@deepseek-ai/dsh-client-<name>`, exports `.`/`./invariant`/`./client`/`./src/*`/`./package.json`, `dshClient` manifest, `files` list), `tsconfig.json` (extends `tsconfig.base.client.json`, one `references` entry per workspace dependency plus `support/invariants`), `tsdown.config.ts` (`clientBundle(id, ['lib/types/index.js', 'lib/types/invariant.js'])`), `src/index.ts` (empty node-half apply), `src/invariant.ts` (companion with a real reason), `src/css-modules.d.ts` when using CSS Modules, `README.md` with the Model Experience section.
+2. **Three registration surfaces, all required** (missing any one fails at a different, later point): the `tsconfig.client.json` aggregate `references` entry; a `dshClient` row in `apps/cli/cordis.yml`; an `apps/cli/package.json` dependency (Loader resolves each config-tree package against the composing app's URL — a row whose package is not an `apps/cli` dependency fails to import). `pnpm-workspace.yaml` already globs `packages/*/*`.
+3. **dshClient manifest semantics**: `platform: 'web'` always; `immediately: true` only for stage-one-prefetch infrastructure rows. `inject` lists package-name dependency edges — they are **informational only** (preflight display, HMR diffing); they do not sequence entry activation or apply order. Activation order is cordis fiber inject waiting on *services*, nothing else.
+4. **Registering into another package's slot**: if the declaring host provides no waitable service, your apply's order relative to the host's is unconstrained — a bare `slots.register` into its slot races boot (intermittent `slot "..." is not declared` page failures). Register with declaration-aware deferral: check `ctx.slots.spec(name)`, otherwise `ctx.slots.subscribe(name)` and register on the declaration event (SlotCore supports subscribing ahead of declaration); make the registration idempotent, and unsubscribe + dispose in the effect disposer. Only take a service edge in `inject` when the host actually provides one (ui-question → `'conversation'` is that case).
+5. Rebuild the bundle (`pnpm --filter <pkg> bundle`) before probing a live `dsh web` server — the registry serves `lib/client.js`, not sources.
+
## New component checklist
1. Compose through register: merge the slot contract into `SlotMap`, declare the slot in its parent entry's `children`, register your component — see the [slot system standard](../../.agents/notes/implemented/architecture/2026-07-22-slot-type-chain-implementation.md). No other composition route exists.

+Any `fixture` query parameter selects the in-memory carrier. `fixture=empty` starts with no Workspace or Session; `fixturePrompt=reject` rejects prompts before acceptance; `fixtureAttach=fail` publishes a Session but rejects its Workspace attachment; `fixtureSessionCreate=drop-response` publishes and frames a Session before dropping the create response; and `fixtureFrames=workspace-first` reverses the default session-first create-frame order. Workspace creation by name/path and caller-preallocated SessionIds remain deterministic enough for assembled Web tests to reconcile list and frame arrival.
+
## Model Experience
None, as the wire consumer layer moves already-composed messages between browser and host; nothing here reaches a model request.

Hot reload for fetch-arrival client plugins. A static-arrival entry composed only into `--dev` graphs (`dsh web --dev`); production graphs omit the row, so the shell-bundled code stays inert.
-The plugin subscribes to the webserver's system SSE channel (`GET /plugins/events`) and reloads one plugin per `rebuilt` frame, serialized through a queue (the bundle handoff slot is single). The sequence per frame — `prefetch` (fetch the new bundle before touching anything), `invalidate`, `registry.delete` (before the fiber: a bare fiber dispose trips the vendored Loader's self-dispose branch, which would mark the entry disabled), drain the old fiber, delete `entry.fiber`, remove owned `<style data-plugin>` tags, `entry.refresh()` re-imports and remounts, `fiber.await()` rethrows startup failures loud. Dependents reload through cordis itself: a fiber's activation epoch strings its service providers' uids, so replacing a provider's fiber cascades every dependent with zero client-side graph analysis. Rebuild detection lives on the webserver: in dev mode it stat-polls each plugin's built `lib/client.js` (`fs.watchFile`) and broadcasts the `rebuilt` frame when the bundle's rev changes, so any tsdown watch process producing the bundle triggers HMR with no builder→host channel.

- * Client module system: the browser peer of Node's internal ESM loader, built
- * as a lazy CJS table. The vendored cordis Loader consumes this object
- * through its `internal` seam (the only call site is `EntryTree.import` →
- * `internal.import`), which keeps entry governance (fiber lifecycle, inject
- * waiting, update/refresh) entirely on the vendored side while this package
- * owns code arrival.
+ * Node half of the client module system (dshClient dual-face package): scans
+ * the host Loader's entries for `dshClient` packages, composes the
+ * `window.__DSH_BOOT__` entry graph (wire single source: {@link WebBootEntry}
+ * in `./client/manifest.ts`), serves `/plugins/<id>/client.js`, taps the
+ * index render to inject the boot manifest, and provides the
+ * `clientModuleHost` service (the HMR node half's registration/notification
+ * face).
*
- * Lazy CJS model (web2 §0): executing a plugin bundle only REGISTERS its
- * factory (`window.__ModuleLoader__.load({id, factory})`); every module body
- * side effect — including CSS injection — lives inside the factory closure
- * and runs at materialization, not at script execution. Materialization
- * (factory(require) → export surface) happens on first import/require and is
- * memoized in {@link ClientModuleLoader.loadCache}; a factory that requires
- * another registered-but-unmaterialized module materializes it recursively,
- * so load order needs no external sequencing.
- *
- * Resolution branch order (import): seed word → shell instance; memoized
- * record → surface; static registry (shell-own modules, e.g. app-shell) →
- * module; registered factory → materialize; graph row → fetch + execute +
- * materialize; anything else → throw (loud — the runtime mirror of the
- * build-time bundle purity gate). The synchronous `require` handed to
- * factories walks the same order minus the fetch branch: fetching is async,
- * so only already-executed bundles can be required — and cross-plugin value
- * imports are a build error anyway.
+ * Scanning is incremental per package — there is no full-rescan code path.
+ * Every cordis `internal/plugin` emission (fiber construction/disposal) marks
+ * the fiber's entry name dirty; a microtask flush reconciles each dirty name
+ * against the live loader entries. The activation pass seeds the same dirty
+ * set with all current entries and flushes synchronously, so first scan and
+ * steady state share one implementation. Package metadata (including the
+ * negative "not a client package" verdict) is cached per name and never
+ * expires — plugin-set changes take effect on restart per the config-source
+ * ruling; bundle content changes reach the graph only through

-Client cordis boot + core services: SlotsService (Service wrapper over SlotCore + 'slots/changed' bridge), SessionsService (list store projection, scope tree, bindings, ancestry), the Session object layer (exported as a type; instances are owned and handed out by SessionsService — the manager/paging internals stay package-internal, tests reach them via src), ClientLoader (`./loader` subpath, statically held by the shell). Contract: api-contracts v3 §4.
+Client cordis boot and React-free object services: SlotsService wraps SlotCore and supplies renderer data sources; SessionsService owns Session objects, list/scope/history state, and page-local Session Intent state; WorkspacesService depends on SessionsService and owns Workspace objects, list/actions, page-local Workspace Intent state, default-target derivation, and the cross-object New Session flow. The runtime fans the shared Host stream into both managers. Contract: api-contracts v3 §4.
+
+## Workspace and Session lists
+
+Workspace and Session lists have independent monotone `pending` → `ready` baseline phases and separate refresh activity/error state. Incremental frames arriving during a list request replay over its response. The first successful baseline establishes Host order; later refreshes update rows and membership without changing the relative order of identities already shown. Workspace recency is derived only after both baselines are ready and never changes Workspace list order.
+
+SlotsService gives the renderer separate bare observables for `useSessions` and `useWorkspaces`; web-react creates the hooks. Workspace business state does not enter `SessionListState` or an entry store.
+
+## Session creation failures
+
+`SessionsService.create` accepts an optional caller-preallocated SessionId. It throws `SessionCreateError` on failure: `requestedSessionId` remains available after transport uncertainty, while `publishedSessionId` is set when `workspace-attach-failed` proves the Host published a real Session before attachment failed. For the New Session flow, the frontend Session object owns its retained prompt and advances it through attachment and send; a partially published Session keeps the same object and prompt while it appears as Ungrouped.

Conversation domain: skeleton (header/tabs/composer/empty state), chat view (grouped step-summary flow, streaming tail isolation, stats line, per-tool row slot with a bash sample registrant), minimal details panel, scope-addressed ConversationService. Contract: api-contracts v3 §7 plus the slot terminal design (store seat / props shares).
+The no-session hero renders the frontend Session Intent from the Session list projection, including its frontend Workspace Intent when no real Workspace exists. It declares `conversation.empty.workspace`, where ui-workspace registers the same picker used by the sidebar. WorkspacesService starts the cross-object flow; each Workspace or Session object owns its own materialization. The Session keeps its identity across publication and retains any prompt that still needs connection or delivery; ConversationRoot reads that `pendingPrompt` from `useSession` and edits or retries it through the scoped ConversationService.
+
The view ring IS a slot: the conversation registration declares the `'conversation.view'` list slot (session scope) in its `children` table, ConversationRoot renders the active entry through its renderSlot share (`only: <active id>`), and view tabs project from the ring ledger's registration options (`id`/`order`/`label`). The chat view is this package's own ring entry; other plugins (ui-trajectory) contribute tabs through plain `ctx.slots.register` — the former package-local view registry (`registerView`/`ViewEntry`/`ConversationViewMap` and the chrome attachment table) is retired, with per-view chrome dissolved into the view components themselves.
Generic tool rows classify the built-in bash, read, search, write, and edit names into dedicated visual variants. The filesystem variants render the edit icon and `Write · <path>` or `Edit · <path>` summary while retaining the shared row-to-details interaction.
Tool rows are slots too — the standalone tool ring (`ToolViewRegistry`/`ctx.toolviews`/outlet) is retired. The chat entry declares the keyed `'conversation.chat.toolview'` hole (session scope; the key space is runtime-open); its render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`. The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openDetails`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '<tool>', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar). Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders).
-Per-session UI state (selection, composer draft, active view) lives in the declared chat store (`stores.ts` `createChatStore`): apply constructs one handle and passes it to the conversation, chat-view, and details registrations, so the session slots share one instance per session (selection written by the chat view, read by details) and the framework owns instance lifecycle and draft persistence. Components are pure — the framework standard kit (`useSession`/`sessionId`/`useSessions`) and the store faces (`useStore`/`actions`) arrive automatically from the registration declaration; the inject factories contribute plain data and callbacks only (send/stop choreography, tab read face, details/paging callbacks, startSession chain).
+Per-session UI state (selection, ordinary composer draft, active view) lives in the declared chat store (`stores.ts` `createChatStore`): apply constructs one handle and passes it to the conversation, chat-view, and details registrations, so the session slots share one instance per session (selection written by the chat view, read by details) and the framework owns instance lifecycle and draft persistence. The frontend Session Intent comes from the Session list projection; after publication, any retained prompt comes from that Session's conversation snapshot. Components are pure — the framework standard kit (`useSession`/`sessionId` when session-scoped, plus global `useSessions`/`useWorkspaces`) and the store faces (`useStore`/`actions`) arrive automatically from the registration declaration; inject factories contribute plain data and callbacks for runtime Session actions, send/stop, tabs, details, and paging.
The resident composer declares the session-scoped single slot `'conversation.composer.control'` and renders its occupant immediately before the send/stop button. Feature packages own the control and its state; ui-conversation supplies only the placement and standard slot shares. The new-session empty-state composer deliberately has no corresponding control slot.

# @deepseek-ai/dsh-client-ui-layout
-Shell plugin: three-column AppFrame (drag handles, concession chain) + ctx.layout viewing-state service (nav, panel widths, persist); defines the sidebar/conversation/details/conversation.empty slots. The sidebar is fixed-width (it never concedes to viewport pressure — only details shrinks, then auto-closes); a closed sidebar retains a 56px control rail while details closes to zero width; collapse/expand animates the grid tracks on the deepsuite sider curve. Contract: api-contracts v3 §5.
+Shell plugin: three-column AppFrame (drag handles and concession chain) plus the `ctx.layout` panel-geometry service; it registers into the runtime-owned `root` slot and declares `sidebar`, `conversation`, `details`, and `conversation.empty`. The sidebar is fixed-width (only details shrinks, then auto-closes); a closed sidebar retains a 56px control rail while details closes to zero width.
-Slot declarations use the composed-props entry form (`owner` share, no full `props`): the exported OwnerShare contracts are `SidebarOwnerProps` / `ConvOwnerProps` / `DetailsOwnerProps` / `EmptyOwnerProps` — registrants reference them via `OwnerOf<'sidebar' | ...>` and compose their own injected share locally. No entry declares `children` (declaring it requires the registered component to carry the slots face — reserved for future business slots): delegation authority is the component-side whitelist, i.e. AppFrame's `ScopedSlots<FrameSlotKey>` face over sidebar/conversation/details/conversation.empty. Since the root-slot rework the frame itself registers into 'root' and renders those child slots at its own render sites; the shell only renders 'root'.
+AppFrame reads the runtime Session projection: `baselinesReady` selects loading, a page-local `SessionListState.intent` selects the empty composer, and a connected Session renders through `SessionProvider`. The conversation and empty-state owner shares are empty; each registrant obtains business data from standard hooks and actions from its own inject face. The sidebar owner share contains only `collapsed` and `width`; navigation actions belong to sidebar's own injected service face.
-The export surface is the cross-package contract only: the AppFrame trio (+ `AppFrameProps`) consumed by the web shell's assembly, `LayoutService` with its store shapes (`NavState`/`PanelState`/`ViewId`), and the OwnerShare contracts. The concession-chain solver (`computeColumns`) and its geometry constants are package-internal; tests import them from `/src`.
+The `/client` export surface is the plugin body (`apply`/`inject`), `LayoutService`, and the four owner-share interfaces. AppFrame, the panel store, and the concession solver remain package-internal; tests import internals through `/src`.

+The selector primes the advisory directory when an existing Host session mounts so the trigger can resolve the catalog name, then refreshes it whenever the menu opens. A frontend Session Intent has no Host model route yet, so the selector stays absent and issues no directory RPC until publication clears the intent.

# @deepseek-ai/dsh-client-ui-sidebar
-Sidebar plugin: session multi-level tree (cwd grouping + parentId nesting), search, by-workspace grouping, state dots, three creation entries. Collapse is a slide + crossfade into the layout-owned 56px rail (open / new session / new workspace / search — search expands and focuses the search box — plus the settings foot): the expanded content freezes at its width and fades in place while the column slides over it, then the rail — whale mark resting, panel icon on hover, tooltips on every control — crossfades in at settle as the wide content unmounts. Contract: the [slot system standard](../../../.agents/notes/implemented/architecture/2026-07-22-slot-type-chain-implementation.md).
+Sidebar plugin: real Host Workspaces in stable Host order, each containing its `sessionIds` in Workspace order with `parentId` nesting; Sessions outside every Workspace appear in a trailing `Ungrouped` section. Search, state dots, and collapse into the layout-owned 56px rail are presentation-local. Contract: the [slot system standard](../../../.agents/notes/implemented/architecture/2026-07-22-slot-type-chain-implementation.md).
-`src/client/contract/slots.ts` is the single-domain contract file: `SidebarRootInjected` (the registrant's own injected share — plain service callbacks: onOpen/onCreate/onToggleSidebar) and `SidebarRootComponentProps = PropsRuntime<'sidebar'> & SidebarRootInjected` (owner `{collapsed,width}` plus the standard `useSessions` hook, resolved off ui-layout's SlotMap declaration, never re-stated). `apply` registers SidebarRoot cast-free against that composition; the inject factory closes over the plugin's own ctx.
+New Session starts the runtime's page-local frontend Session Intent; a real Workspace's "+" starts one targeted to that Workspace. The Workspace header "+" opens ui-workspace's shared picker, whose selection also targets a frontend Session. A Workspace Intent does not appear in the sidebar.
-There is no plugin store: rows derive in the component (`useMemo` over the `useSessions` snapshot + local expansion/search state) through the pure `deriveRows` in `tree.ts`.
+`SidebarRootComponentProps` composes the layout owner share, the global `useSessions` and `useWorkspaces` hooks, the declared `sidebar.workspace` child slot, and injected `startSession`, `open`, and sidebar-toggle callbacks. There is no plugin store: `deriveGroups` consumes object-layer snapshots and component-local expansion/search state.
The `/client` export surface is the plugin body (`apply`/`inject`) plus the contract types only — SidebarRoot, the row components, and the tree derivation are internal (the slot registration closes over them; tests import src paths directly).

Chain-kind slots invert keyed routing — entries self-nominate instead of the dispatch site picking an `entryKey`: each registration carries a pure `ChainSelect` selector (plus optional ascending `priority`, ties in registration order), the first non-null return elects its entry and becomes the component's `matched` prop, and all-null falls to the owner's `renderSlotChain` fallback (`ChainRenderOpts`).

+The standard-kit interfaces (`SessionStandardProps`, `GlobalStandardProps`) are declared empty here and merged by the runtime package (same declare-merge pattern as SlotMap keys). The renderer binds the runtime's session and workspace observable sources into selector hooks. Inject factory parameters derive from the declaration (`InjectParams`): session slots get `sessionId`, a declared store appends baked `actions`, nothing else — data access lives in the apply closure's ctx.
The store family (`defineStore` spec in / `StoreHandle<T, A>` out) types the store seat: `init` infers the state schema, `actions` is the complete draft-transform write set, `BakedActions` strips the draft parameter into the callbacks components and inject factories receive. The `defineStore` value implementation lives in the runtime package (the engine's home) and satisfies the `DefineStore` contract exported here. Engine products and the renderer host contract carry bare snapshot sources (`getSnapshot`/`subscribe`), never React hooks — hook binding is the render machinery's side of the seam; only the props-contract hook type (`SnapshotSelectorHook`) lives here.

+# @deepseek-ai/dsh-client-ui-workspace
+
+Shared Workspace picker plugin. `WorkspacePicker` is registered into the sidebar's `sidebar.workspace` slot and the page-local Session Intent hero's `conversation.empty.workspace` slot, so both surfaces use the same menu and creation modals.
+
+The picker lists real Host Workspace entities through the global `useWorkspaces` hook. Selecting a Workspace invokes the slot owner's `onPick` callback to retarget the frontend Session object; the existing-folder and create-new actions first create a real Workspace through the object layer, then select it. Create-new disables names already present in that list, while the Host remains authoritative for concurrent or non-UI callers. The runtime Session and Workspace services own materialization.
+
+Both target slots are declared by other plugins, so `apply` registers through declaration-aware deferral and re-registers after a declaring slot is restored.
+
+## Model Experience
+
+None, as the picker is browser chrome; nothing here reaches a model request.
+
+#### KV Cache effect
+
+None; this package neither assembles nor sends a provider request.
+
+## Known Limitations and Deferred Work
+
+- **No Workspace rename/delete controls** — the picker supports selection and creation only.
+- **Existing-folder entry is manual path input only** — Host creation failures are shown in the modal.

The standard TUI and ACP demo bundles mount it, while other hosts may call the service directly.
+`ctx.sessionReferences` prepares bounded, read-only snapshots of other sessions as prompt-prefix context. It consumes `ctx.sessionQuery` and the backend-independent compact checkpoint marker; SQLite FTS is not required. The standard TUI bundle mounts it, while other hosts may call the service directly.
## Public API
- `listCandidates(agent, query?, limit?)` lists sessions other than `agent.id`, filters case-insensitively by id or cwd, and ranks same-cwd, cwd-less, then other-cwd records while preserving `listSessions()` creation order within each group. Each selected candidate uses its latest log-backed title as the mention label and falls back to the session id; titles and message bodies are not searched.
-- `prepare(agent, content, references, signal?)` preserves first-mention order, deduplicates ids, rejects self-reference and more than the configured distinct-source limit, reads every source in parallel, and returns detached content plus zero or one aggregated `HookContext`. Any invalid reference, failed read, cancellation, or budget failure rejects before the host calls `send()` or `steer()`.
+- `prepare(agent, content, references, signal?)` preserves first-mention order, deduplicates ids, rejects self-reference and more than the configured distinct-source limit, reads every source in parallel, and returns detached content plus zero or one aggregated `HookContext`. Any invalid reference, failed read, cancellation, or budget failure rejects before the host calls `followup()` or `steer()`.
- `encodeSessionReferenceUri()` and `decodeSessionReferenceUri()` implement `dsh-session:<base64url(JSON.stringify(sessionId))>` so every JavaScript string id round-trips exactly. `formatSessionReferenceMention()` emits `@[label](uri)`, and `parseSessionReferenceText()` replaces Markdown mentions or bare canonical URIs with readable `@label` text while returning structured references. Explicit Markdown mentions reject every malformed URI; bare text is considered a reference only when a non-empty base64url-shaped payload follows the scheme, and a matching noncanonical candidate still fails. Empty or punctuation-only scheme mentions remain ordinary discussion text.
## Snapshot semantics
Preparation calls `ctx.sessionQuery.readSurface()` once per distinct source and never rereads it after enqueue. It projects only direct-user `user/message`, direct-user `steering/message`, assistant text, and `user/message` checkpoints carrying the canonical `dsh-compact` source marker from the folded current surface. For a source prompt that already contains baked prefix context, projection reads only its model-hidden display content, preventing recursive snapshot propagation. Shadowed pre-compaction events, tools, reasoning, context, plugin-generated user messages other than marked compact checkpoints, and unfinished assistant chunks are excluded. A compacted source therefore contributes its latest checkpoint plus retained later conversation, not restored shadowed text.

The schedule therefore applies across turns and resumed processes without process-local cache state. It reduces append frequency and history growth but never removes an existing reading, and sessions schedule independently.
Step 1 measures from the latest preceding model-visible message, including the prompt that opened the turn. Later steps measure from the preceding time-context event in the same turn. Both baselines use durable session-event timestamps; backward wall-clock movement clamps elapsed time to zero. A missing first-step baseline, or a later step with no earlier same-turn reading because interval suppression skipped it, reports `unavailable`.

-Model-visible text contains no hidden state markers. Each dynamic context event instead carries JSON metadata with a versioned list of `{ action, scope, path, digest? }` changes.

If the owning `step/end` arrives before a matching context reaches the log, the plugin clears the pending transition and its version fast path so the next successful touch can load it again.

An unchanged path and SHA-1 content digest is not injected again. A per-session, per-scope metadata cache stores only `{ path, version, digest, trimmedDigest }`: when the provider's opaque `FsVersion` and the effective visible state both match, reconciliation skips the content read; a changed version triggers a bounded read and SHA-1 confirmation before any model-visible update. The `trimmedDigest` — SHA-1 over the whitespace-trimmed content — is the per-directory duplicate key, so an unchanged file can still be removed when an earlier candidate converges on its content. Resume works because SHA-1 state is persisted in the session log, while an empty in-memory version cache merely causes one confirming read. Compaction re-arms a scope after its context event leaves the visible surface even when the cached version is unchanged. A removal is a tombstone, so a later candidate reappearance is loaded again. Only model-visible changes actually rendered within the byte budget enter metadata, pending state, and the version cache; an omitted change remains eligible for a later touch, while a same-digest version refresh updates metadata only.

+The concrete `ReactLoopAgent` adapter, its `Inbox`, `runLoop`, and instance-bound publication/start controls are package-internal. The package root exports only the plugin/service/config contract, and the package exports map exposes no `./src/*` escape hatch; lifecycle owners create agents through `ctx.agents` rather than naming, constructing, or starting driver internals. One prepared session can be claimed by only one concrete driver, and everything observable happens through session events and the `agent/*` event taxonomy.
-Each concrete `send()` materializes content, resolved source, and attached contexts once as a detached, deeply frozen lossless-JSON FIFO item. If claimed, it is the sole ordinary message in its turn; its contexts are the prompt waterfall's default additional contexts and therefore materialize only after admission. Absent or `separate` placement appends an independent `context/message`; `prompt-prefix` placement bakes the context, the stable `## My request:` delimiter, and effective request into one `user/message`, whose model-hidden envelope retains display content and context descriptors. The waterfall's returned allow is authoritative, so a listener wrapping `next()` preserves downstream `content` and `additionalContexts` unless it intentionally replaces them. A successor waits for the preceding ordinary turn's checkpoint to settle, while cancellation, disposal, a prompt block, or a pre-start failure may drop its contexts with the message. Running `steer()` enters the same record shape in the steering FIFO without dispatching `agent/prompt-submit`; its next checkpoint applies the same separate-or-prefix placement to `steering/message`, while policy can still stop before another step. Steering left after turn close and its checkpoint becomes later queued input with contexts intact unless terminal turn policy, cancellation, or disposal discards it. Open-turn `inject()` uses the same accepted-value boundary but defers in a FIFO while the current step executes assistant tool calls; successful batches place it after all results, and interrupted batches drain it before turn close. Malformed data throws before enqueue or append.
+`ReactLoopAgent.send()` implements the public fully resolved acceptance path. The `followup()`/`queue()`/`steer()`/`inject()` helpers resolve every optional field before delegating to it; direct callers provide mandatory content, source, contexts, metadata, target, and wakeup facts through `ResolvedAgentInput`. `followup()` and `queue()` join the ordinary FIFO, respectively waking or leaving an idle driver parked. If claimed, an ordinary item is the sole message in its turn, and its contexts are the prompt waterfall's default additional contexts that materialize only after admission. Absent or `separate` placement appends an independent injected `user/message`; `prompt-prefix` placement bakes the context, the stable `## My request:` delimiter, and effective request into one `user/message`, whose model-hidden envelope retains display content and context descriptors. The waterfall's returned allow is authoritative, so a listener wrapping `next()` preserves downstream `content` and `additionalContexts` unless it intentionally replaces them. A successor waits for the preceding ordinary turn's checkpoint to settle, while cancellation, disposal, a prompt block, or a pre-start failure may drop its contexts with the message. Running `steer()` or equivalent `send()` routing enters the same record shape in the steering FIFO without dispatching `agent/prompt-submit`; its next checkpoint applies the same separate-or-prefix placement to `steering/message`, while policy can still stop before another step. Steering left after turn close and its checkpoint becomes later queued input with contexts intact unless terminal turn policy, cancellation, or disposal discards it. `inject()` and non-waking next-step acceptance require an empty context tuple, bypass both FIFOs, and append durable context directly: an open-turn injection defers in a FIFO while the current step executes assistant tool calls (successful batches place it after all results, interrupted batches drain it before turn close), and an idle injection wraps a one-shot `injection` turn. Every FIFO enqueue publishes `agent/inbox/enqueue`; the driver's claims publish `agent/inbox/dequeue`, and `cancel()` without `keepInbox` publishes `agent/inbox/discard`. Malformed data throws before enqueue or append.

Most interception points are cooperative waterfalls returning seam-specific decisions. Turn-scoped asynchronous seams receive one explicit `AbortSignal`, with `signal` immediately before a waterfall's final `next`; listeners may cooperate but must not retain it as authority over another turn. The signal remains authoritative through terminal policy and is retired immediately before `turn/end` publication, so terminal observers and the following durability flush cannot cancel completed turn work. `agent/pre-step` and `agent/post-step` are serial checkpoints around a step's durable work, while `agent/request-error` is the failed-model-request recovery waterfall: it receives the exact error, normalized failure facts, immutable prior-retried facts, and signal after the failed step closes; a retry opens a new numbered step. `agent/turn-stop` is the terminal serial fold: it runs after ordinary continuation and steering folding, and a returned stop remains in force through turn close and flush so later steering cannot create an extra step or turn. Ordinary queued prompts remain intact. Effective broad cancellation first emits the observe-only `agent/cancel-requested` with its resolved typed cause, then clears queues and aborts; notification failures are contained and cannot veto the stop. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) owns signal lifetime; the [agent-scope runtime-design Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.md#three-execution-boundaries-are-deliberately-one-way) owns scoped dispatch and terminal settlement.

Turn and step boundaries and the model token stream are durable `session/event` facts rather than mirrored `agent/*` notifications.

### Agent interface (`types.ts`)
-The handle every plugin programs against:
+`Agent` is a structural interface. `followup()`, `queue()`, `steer()`, and `inject()` name common caller intents; `send(ResolvedAgentInput)` exposes the same acceptance path when a caller already has exact routing facts ([decision](../../../.agents/notes/implemented/architecture/2026-07-24-intent-named-agent-delivery.md)). Every `ResolvedAgentInput` field is mandatory, and its discriminated union excludes attached contexts from non-waking next-step injection. FIFO acceptance returns an opaque `AgentMessageId` carried by that item's `agent/inbox/enqueue`/`dequeue`/`discard` events. The driver snapshots content, resolved source, attached contexts, and model-hidden metadata as one detached, deeply frozen lossless-JSON record before notification and enqueue; invalid data throws synchronously. The helpers apply defaults: omitting `options.source` on `followup()`, `queue()`, or `steer()` attests direct human input as `{ kind: 'user' }`, so every non-human producer labels its content.
-- `agent.send(content, options?)` — queue one independent FIFO item. If claimed, that item becomes the sole ordinary message in its turn; a claimed FIFO successor waits for that turn's checkpoint to settle. Broad cancellation, disposal, or a pre-start failure may instead drop it without a turn. Omitting `options.source` attests direct human input as `{ kind: 'user' }` and may authorize policy consumers, so plugins, schedulers, and other non-human producers provide their own source. Content, resolved source, and `options.contexts` become one detached, deeply frozen lossless-JSON record before `agent/queued` and enqueue; invalid data throws synchronously, and caller or notification-listener in-place mutation cannot change the log or model input. After admission, separate contexts become `context/message` events, while prompt-prefix contexts are baked before the effective request in the same `user/message`; a block or replacement of the default additional-context decision can discard them. The [one-send-one-turn Agent Note](../../../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md) owns the turn rationale.
-- `agent.steer(content, options?)` — while running, queue steering for the next checkpoint without dispatching `agent/prompt-submit`; when idle, delegate to `send()`. Attached contexts remain in the same frozen record; separate contexts append immediately after the steering event, while prompt-prefix contexts are baked into that steering event. Both survive late-steering conversion to queued input and disappear with their message on cancellation or terminal discard. Policy can still stop before another step; after turn close and its checkpoint, remaining steering becomes later queued input unless terminal turn policy, cancellation, or disposal discards it.
-- `agent.inject(content, options?)` — accept detached in-session context without running the model; the next request sees its `context/message` with `content` rendered verbatim as a user-role message. `options.meta` persists opaque JSON state without rendering it. While a turn is open it joins that turn, deferring FIFO while the current tool batch executes and draining before turn close if execution is interrupted; while idle it is wrapped in a one-shot `injection` turn and durability checkpoint ([the turn-enclosure invariant](../../../.agents/notes/implemented/architecture/2026-06-15-turn-enclosure-invariant.md)).
-- `agent.cancel(cause?)` — cancel ALL pending work: an omitted cause means `{ kind: 'user' }`; TypeScript restricts callers to the `user | parent` union, and an active holder copies its discriminant into a detached frozen signal reason before aborting. An effective call emits `agent/cancel-requested` with the cause before clearing queued and steering work; observers may synchronize state but cannot veto cancellation. The same-process typed seam adds no runtime validation or compatibility fallback for untyped callers. Repeated active-turn cancellation is first-wins for the signal, and idle cancellation is a safe no-op with no notification. ACP maps to `user`, while in-process parent propagation maps to `parent`. The cause is runtime-only; durable `turn/end` stays coarse `aborted`.
+- `agent.followup(content, options?)` — queue one independent FIFO message as its own turn and wake the driver. After admission, separate contexts become injected `user/message` events, while prompt-prefix contexts are baked before the effective request in the same `user/message`; a block or replacement of the default additional-context decision can discard them. The [one-send-one-turn Agent Note](../../../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md) owns the turn rationale.
+- `agent.queue(content, options?)` — queue the same ordinary message without waking an idle driver. A lone queued item leaves `whenIdle()` resolved and rides along before the next waking message.
+- `agent.steer(content, options?)` — while running, queue steering for the next checkpoint without dispatching `agent/prompt-submit`; while idle, create a waking ordinary turn. Attached contexts remain in the same frozen record; separate contexts append immediately after the steering event, while prompt-prefix contexts are baked into that event. Both survive late-steering conversion to queued input and disappear with their message on cancellation or terminal discard. Policy can still stop before another step; after turn close and its checkpoint, remaining steering becomes later queued input unless terminal turn policy, cancellation, or disposal discards it.
+- `agent.inject(content, options?)` — accept detached in-session context without running the model; the next request sees its `user/message` (default plugin source) with `content` rendered verbatim as a user-role message. `InjectOptions` deliberately has no attached contexts. `options.meta` persists opaque JSON state without rendering it. While a turn is open the injection joins that turn, deferring FIFO while the current tool batch executes and draining before turn close if execution is interrupted; while idle it is wrapped in a one-shot `injection` turn and durability checkpoint ([the turn-enclosure invariant](../../../.agents/notes/implemented/architecture/2026-06-15-turn-enclosure-invariant.md)). Injection bypasses the FIFOs and emits no `agent/inbox/*` event.
+- `agent.send(input)` — accept a fully specified route without helper defaults. `next-turn` targets the ordinary FIFO; `next-step` with wakeup targets steering and falls back to a waking ordinary turn while idle; `next-step` without wakeup is injection and requires `contexts: []`. Callers provide `meta: undefined` explicitly when they have no metadata.
+- `agent.cancel(cause?, options?)` — cancel the active turn and, unless `options.keepInbox`, ALL pending work: an omitted cause means `{ kind: 'user' }`; TypeScript restricts callers to the `user | parent` union, and an active holder copies its discriminant into a detached frozen signal reason before aborting. An effective call emits `agent/cancel-requested` with the cause before clearing queued and steering work; dropped items are reported on `agent/inbox/discard`, and observers may synchronize state but cannot veto cancellation. `keepInbox: true` aborts the turn but preserves queued and steering items (no discard, and un-started work is not dropped). The same-process typed seam adds no runtime validation or compatibility fallback for untyped callers. Repeated active-turn cancellation is first-wins for the signal, and idle cancellation is a safe no-op with no notification. ACP maps to `user`, while in-process parent propagation maps to `parent`. The cause is runtime-only; durable `turn/end` stays coarse `aborted`.
- `agent.whenIdle()` — resolve once the agent reaches quiescence after settling out of `running` (idle → immediately; disposed → awaits the loop exit). A non-owner's quiescence-observation hook: it observes the work settling WITHOUT tearing the agent down. Teardown is separate — a lifecycle owner stops and unregisters via `AgentHandle.dispose()`, which awaits the loop exit directly.

# @deepseek-ai/dsh-acp-demo
-The **ACP server app**: a Cordis app plugin that composes the default agent spine ([`@deepseek-ai/dsh-agent-spine-demo`](../agent-spine-demo/README.md)) with the front-door cluster an [Agent Client Protocol](../../ui/acp/README.md) server needs, and a `bin` that boots a leaf `cordis.yml` speaking ACP JSON-RPC on stdio.
+ACP automation server app: the default agent spine, client-created agents through [`@deepseek-ai/dsh-acp`](../../acp/acp/README.md), JSONL persistence, and semantic checkpointing behind one JSON-RPC stdio bin. Programmatic clients create fresh sessions; this package mounts no human UI.
-It is the structured counterpart to [`@deepseek-ai/dsh-tui-demo`](../tui-demo/README.md): both consume the same spine, but ACP creates sessions from its client and reserves stdout for its wire protocol.
+## Composition
-## What it bakes in — and what it deliberately omits
-
-stdout is the ACP JSON-RPC channel, so the cluster is defined as much by what it LEAVES OUT as what it includes:
-
-| Plugin | Why |
+| Plugin | Role |
|---|---|
-| `@deepseek-ai/dsh-agent-spine-demo` | the spine, pre-creating **no** agents (ACP `session/new` creates them on demand) |
-| `@deepseek-ai/dsh-commands` | the human-command registry used for ACP discovery and direct slash dispatch |
-| `@deepseek-ai/dsh-command-goal` | the discoverable direct `/goal` producer; the app enables the spine's persisted-goal stack with it |
-| `@deepseek-ai/dsh-user-interaction` | the human question/answer seam used by clients that can complete ACP elicitation requests |
-| `@deepseek-ai/dsh-session-persistence-jsonl` | durable JSONL session log (the bridge advertises `loadSession`) |
-| `@deepseek-ai/dsh-session-query-sqlite` + `@deepseek-ai/dsh-session-reference` | combined exact/FTS session queries and bounded `dsh-session:` snapshots |
-| `@deepseek-ai/dsh-session-checkpoint-policy` | semantic durability barriers before model requests and top-level tool effects, plus completed-step checkpoints |
-| `@deepseek-ai/dsh-acp` | the bridge that owns stdout for JSON-RPC and provides ACP-backed user answers when a leaf explicitly exposes a user-question tool |
-| ~~`@deepseek-ai/dsh-tool-ask-user`~~ | **omitted by default** — ACP elicitation support is still client-dependent, so leaves must opt in deliberately |

-The app owns this cluster through one ordered Cordis effect. Teardown drains the ACP bridge before removing the checkpoint policy or persistence backend, so a graceful disconnect persists the real closing `step/end` and `turn/end` events rather than leaving crash recovery to synthesize them. Because the package wires no logger entry, an ACP leaf has **nothing to get wrong by default**: it only picks backends. A leaf author can still add `@cordisjs/plugin-logger-console` as a sibling entry, so the rule remains: never add a stdout logger to an ACP leaf; use a stderr exporter instead.
+The app does not install commands, user interaction, session navigation, configuration pickers, or a stdout logger. It owns these plugins through one ordered effect so the query service is ready before ACP accepts work and ACP sessions quiesce before checkpointing and persistence detach. Leaf configurations supply LLM, executor, sandbox, approval, filesystem, and model-facing tool plugins.
## Config
| Key | Default | Routed to |
|---|---|---|
-| `provider` | (required) | the initial provider route for each per-session agent the bridge creates; ACP model selection may replace it per session |
-| `model` | (required) | the initial model for each per-session agent; ACP clients may switch among adapter-advertised models |
-| `maxParallelToolCalls` | agent-loop default | positive-integer concurrent tool-call cap shared by the bundled loop's agents; `1` is serial |
-| `persona` | — | the deployment persona template (may reference `{{provider}}`/`{{model}}`/`{{cwd}}`), routed to `dsh-system-prompt` |
-| `toolOrder` | — | explicit model-facing tool order (a name list with one `'<unlisted-tools>'` rest entry; absent — lexicographic; an unregistered name fails each turn at prompt assembly), routed to `dsh-system-prompt` |
-| `dshHome` | `$DSH_HOME` or `~/.dsh` | Harness home exposed to model bash and used by local skill discovery |
-| `sessionTitle` | spine example limits | fallback title word/byte limits routed through `dsh-agent-spine-demo` |
-| `tools` | `{ mode: 'native' }` | tool-registry presentation config (`native` / `code` / `both`), routed through `dsh-agent-spine-demo` |
-| `workspaceContext` | (required) | workspace-instruction byte budget/config, or `false`; routed to the providerless-safe `dsh-workspace-context` plugin |
-| `skills` | owner defaults | registry-cache, local-provider, and model-facing skill-tool config, routed through `dsh-agent-spine-demo` |
-| `toolBash` | owner defaults | model-facing bash config routed through `dsh-agent-spine-demo`, including bash's producer-local `enableRunInBackground` |
-| `toolTasks` | owner defaults | generic `task_output` wait bounds routed through `dsh-agent-spine-demo` |
-| `goals` | owner defaults | persisted goal-domain and model-tool config; `false` removes the goal stack and `/goal` producer |
-| `llmRetry` | owner defaults | bounded transient model-request retry policy routed through `dsh-agent-spine-demo` |
-| `persistenceRoot` | `./.sessions` | the JSONL backend's root directory and the parent of the derived `session-query.db` index |
-| `packChunks` | `false` | write delta-chunk runs as packed storage rows (the JSONL backend's `packChunks`) |
-| `persistenceCompression` | `'zstd'` | JSONL artifact encoding (`'zstd'` or raw `'none'`) |
-| `sessionReferences` | service defaults | cross-session candidate and snapshot limits routed to `dsh-session-reference` |
+| `provider` | required | Provider route for each ACP-created agent. |
+| `model` | required | Model for each ACP-created agent. |
+| `maxParallelToolCalls` | agent-loop default | Positive-integer tool-call concurrency cap; `1` is serial. |
+| `persona` | — | Deployment persona template for `dsh-system-prompt`. |
+| `toolOrder` | lexicographic | Explicit model-facing tool order for `dsh-system-prompt`. |
+| `tools` | `{ mode: 'native' }` | Native, Code Mode, or combined model tool transport. |
+| `dshHome` | `$DSH_HOME` or `~/.dsh` | Harness home shared by bash and local skill discovery. |
+| `sessionTitle` | spine example limits | Durable fallback-title limits; titles remain off the ACP wire. |
+| `persistenceRoot` | `./.sessions` | JSONL backend root and parent directory of the derived `session-query.db` index. |
+| `packChunks` | `false` | Pack consecutive delta-chunk events in storage. |
+| `persistenceCompression` | `zstd` | Checksummed Zstandard frames or raw `none`. |
+| `workspaceContext` | required | Workspace-instruction byte budget/config, or `false`. |
+| `skills` | owner defaults | Skill registry, local provider, and model-facing skill tool. |
+| `toolBash` | owner defaults | Model-facing bash tool config. |
+| `toolTasks` | owner defaults | Generic background-task control config, or `false`. |
+| `goals` | owner defaults | Persisted same-session goal domain and model tools, or `false`. |
+| `llmRetry` | owner defaults | Bounded transient model-request retry policy. |
-The leaf supplies the swappable backends: an LLM adapter (`llm-deepseek` for the real model, `llm-replay` for keyless snapshot replay), a bash executor, and optionally a `ctx.fs` provider. Workspace context becomes a no-op without `ctx.fs`; the shipped [`examples/acp-agent/cordis.yml`](../../../examples/acp-agent/cordis.yml) selects `dsh-sandbox-policy`, `dsh-fs-sandbox`, `dsh-fs-policy`, and `dsh-tool-fs` so baseline instructions and model-facing `read`/`write`/`edit` share one provider, sandbox mode, workspace root, and observed-version policy.
+The shipped [`examples/acp-agent/cordis.yml`](../../../examples/acp-agent/cordis.yml) adds the DeepSeek adapter, sandboxed bash and filesystem providers, one-shot approval policy, compaction, subagents, workflows, hooks, and model-facing tools. The app supplies the derived session-query index, while the model-facing query consumer remains an explicit leaf opt-in. Snapshot overlays replace only nondeterministic providers or policy values.
-## The bin
+## Bin
-`dsh-acp-demo [--config path-to-cordis.yml]` (short form `-c`; default `./cordis.yml`):
-
-- loads a gitignored `.env` from the cwd — **skipped** in snapshot REPLAY so a stray key can never trigger a live call;
-- honors `DSH_SNAPSHOT=replay` by booting the sibling `cordis.snapshot.yml` (the keyless replay tree, `llm-replay` in place of `llm-deepseek`);
-- in a snapshot run, disposes the context on stdin EOF so the session log is fully flushed before exit.
-
-The repository installs Loader's optional `node-addon-require-builtin` peer, so the built bin resolves bare plugin specifiers through the internal module loader under plain Node. (`demo:acp` runs under tsx, whose tsconfig `paths` map resolves them instead.)
-
-All diagnostics go to **stderr** — stdout is the protocol.
+`dsh-acp-demo [--config path-to-cordis.yml]` (short form `-c`; default `./cordis.yml`) loads the gitignored `.env`, except in replay mode; `DSH_SNAPSHOT=replay` selects the sibling `cordis.snapshot.yml`; stdin EOF disposes the context and flushes sessions before exit. Loader's installed optional `node-addon-require-builtin` peer resolves bare plugin specifiers for the built bin under plain Node. Diagnostics use stderr because stdout is the ACP wire.
## Model Experience
-Indirectly, through `dsh-agent-spine-demo` and `dsh-acp`, which compose each ACP agent's prompt, goal tools, and message history. Direct `/goal` input and output remain outside the model, while accepted mutations append domain-owned model-visible snapshots.
+Indirectly, through `dsh-agent-spine-demo` and the leaf's model-facing plugins. ACP prompt text becomes the ordinary logged user message; protocol metadata and permission choices do not enter the model request.
#### KV Cache effect
-No direct invalidation; the named consumer owns any request-prefix changes.
+Append-only per session; the app adds no request-prefix content itself.
## Known Limitations and Deferred Work
-- **JSONL persistence is baked in** — config chooses its root but cannot select a different backend; that requires a sibling entry or differently composed app package.
-- **User-question and approval mechanisms are omitted by default** — the bridge can answer both when their services/tools are composed, but this front door does not enable those deployment policies itself.
-- **A leaf can still corrupt stdout** — the app mounts no console logger, but it cannot prevent a sibling leaf entry from writing non-protocol bytes to the ACP channel.
+- **JSONL persistence is fixed** — a different backend requires another composition.
+- **Sibling plugins can corrupt stdout** — the app cannot prevent another entry from writing non-protocol bytes.
+- **Fresh automation sessions only** — resume and human interaction belong to other front doors.

At most one goal is current. Creation produces an active revision-one goal and arms it. A non-complete goal must be edited, transitioned, or cleared; a completed goal may be replaced by a globally fresh id. Edits retain phase, blocker reason, and activation. Pause, completion, blocking, and clear disarm activation. A block records a policy-owned lower-kebab-case code plus a normalized free-form explanation; provider limits, configured budgets, execution errors, and requests for human input all use this one durable phase rather than multiplying lifecycle states. Resume accepts a stopped phase or a disarmed active goal only while the configured round cap has remaining capacity; it clears any former blocker reason. An active armed goal rejects the redundant operation.
-Every non-clear mutation appends a complete versioned snapshot through `agent.inject()`; clear appends a revisioned tombstone. The `context/message` content projected verbatim to the model, its `{ kind: 'goal' }` source, and its metadata must agree exactly. Replay rejects malformed shapes, source/content drift, discontinuous revisions, illegal lifecycle transitions, non-monotonic per-goal timestamps, and non-sequential goal rounds. Mutation timestamps clamp against the preceding goal update when wall time moves backward.
+Every non-clear mutation appends a complete versioned snapshot through `agent.inject()`; clear appends a revisioned tombstone. The round-zero `user/message` content projected verbatim to the model, its `{ kind: 'goal' }` source, and its metadata must agree exactly. Replay rejects malformed shapes, source/content drift, discontinuous revisions, illegal lifecycle transitions, non-monotonic per-goal timestamps, and non-sequential goal rounds. Mutation timestamps clamp against the preceding goal update when wall time moves backward.
Injection may append immediately or wait in an active tool-batch FIFO. The service overlays accepted pending changes in memory and reconciles each exact payload when it enters the log, so consecutive model-tool mutations see their own latest revisions without treating an unlogged cache as durable state. Reentrant append observers see each accepted mutation exactly once, and incremental replay retains its cursor at the first corrupt event. `goal/changed` fires after the append or enqueue succeeds; listener failures are contained.

Complete and blocked also accept the exact current goal round: a goal-sourced `user/message` whose id, revision, and round equal the folded current goal. A goal-round blocked call is mechanically rejected until `blockedAfterConsecutiveRounds`; the model judges whether the same condition actually persisted and must describe it in `blocked_reason`. Direct human authority may stop a goal immediately.

Session model routing is a session-domain contract. `session.history` returns the selected `modelTarget`, `session.models` returns that target with provider-grouped advisory model metadata and provider-local lookup failures, and `session.selectModel` replaces the target selected for the next prompt-assembly boundary. Catalog membership is not validation: a registered provider may accept an unlisted model, while an unregistered provider returns `model-unavailable`.
+Workspace and Session lists are separate reconnect baselines. `workspace.create` creates a unique name or adopts an existing directory, `session.create` accepts an optional preallocated Session id, and `host/workspace-changed` plus `host/session-added` carry committed increments in either arrival order. Frontend Workspace and Session Intents are client-only and have no wire method.

-- **`respond` routing is shipped, but pending-interaction state is host-side work** — the wire shape (POST `/api/respond`, `RpcReceipt`) is final; the pending table that makes late/duplicate answers meaningful lives in `dsh-host-runtime` and is still a stub there.
+- **`respond` routing is shipped, but pending-interaction state is host-side work** — the wire shape (POST `/api/respond`, `RpcReceipt`) is final; the pending table that makes late/duplicate answers meaningful lives in `src/api-proxy.ts` and is still minimal (questions only, no approvals).
- **Reserved seams stay out of `RpcMethodMap`** — `session.fork`, `prompt.mode: 'inject'`, `task.list`, `host.listModels`, and a describe `hostInstanceId` are documented reservations; an unknown method fails loud at envelope parse rather than getting a not-implemented code.
- **No protocol version field** — client and host ship together; `host.describe` gains a version negotiation field only when an independently released client exists.

-# @deepseek-ai/dsh-host-runtime
-
-Host runtime assembly for `dsh`: `bootHost` composes the core plugin spine (LLM service + DeepSeek adapter, sessions with JSONL persistence and immediate fallback titles, optional first-message model summaries, system prompt, tools, agents, agent loop, workspace instructions, local bash, and the provider-neutral user-interaction service), `createApiProxy` implements the [`dsh-host-apiproxy`](../apiproxy/README.md) contract over that composition, and `startHost` is the one-step shell seam returning `{ api, handler, defaults, ctx, dispose }`.
-
-Which plugins mount and with what defaults is decided only here — shells must not `ctx.plugin` to alter the assembly. `RunningHost.ctx` is a formal seam with exactly two sanctioned uses: mounting protocol front-door plugins (e.g. a future `dsh acp`) and headless session-event subscription; consuming clients must not bypass `api` through it.
-
-## Configuration
-
-| Key | Default | Contract |
-|---|---:|---|
-| `persistenceRoot` | (required) | Root directory for JSONL session persistence. |
-| `workspaceContext` | (required) | [`AGENTS.md`/`CLAUDE.md` loader](../../context/workspace-context/README.md) config with an explicit `maxBytes`, or `false` to disable it. |
-| `provider` | `'deepseek'` | Default provider route injected as agentOptions on create/resume and reported by `host.describe`. |
-| `model` | `'deepseek-v4-flash'` | Default model id, same single source as `provider`. |
-| `cwd` | `process.cwd()` | Default project directory for a session whose create request omits `cwd`. |
-| `sessionTitle` | 5 words / 40 fallback bytes / 80 accepted bytes | Deterministic fallback and accepted-title limits. |
-| `sessionTitleLlm` | disabled | `true` enables the 5-word / 10-CJK-character, 4,096-input-byte, 64-output-token, 60-second first-message policy; an explicit config overrides it. An omitted route inherits the logged main-request provider and model. |
-
-## ApiProxy implementation notes
-
-Unary methods take the narrow `RpcRequest<P>` and echo `request.rpcId`; a prompt's rpcId rides `MessageSource` into the `user/message` event so clients can promote optimistic echoes. `history`/`prompt` on a cold session implicitly resume it, deduplicating concurrent calls through an in-flight table; `history` paginates backwards on message boundaries (never mid-message). The mux stream replays a `session/subscribed` baseline per attached session and every still-pending question with its original rpcId. Question responses, including blank per-item answers, are validated against the owning session and exact request before an atomic first-wins claim; answer, whole-request cancellation, owner abort, and provider disposal broadcast `question/resolved`. The host stream carries session lifecycle, running flips, and `agent/error` as the only outlet for live failures with no turn position.
-
-The Web front door installs the shared `installAgentLlmTarget` coupling for every created or resumed agent. A session starts from the latest logged `request/header` route when one exists, otherwise from the Host default. `session.models` discovers every registered provider concurrently, keeps successful groups when another provider fails, and inserts the current target as an unlisted row when its provider omits it. A selection changes the mutable session target immediately; prompt assembly snapshots it atomically with request routing, so a change during a running step first applies to the next assembled step.
-
-## Model Experience
-
-Indirectly, through the non-blocking first-message title request owned by [`dsh-session-title-llm`](../../session-title/session-title-llm/README.md) when `sessionTitleLlm` is enabled, the provider/model defaults injected into created and resumed agents, the other model-facing plugins `bootHost` mounts, and the logged [workspace-instruction prefix](../../context/workspace-context/README.md#prompt-shape) when `workspaceContext` is enabled.
-
-#### KV Cache effect
-
-No main-request invalidation; when enabled, the auxiliary title request has its own cache behavior and leaves the conversation prefix unchanged.
-
-## Known Limitations and Deferred Work
-
-- **Question waits are process-memory state** — browser reconnects recover them, but a host process restart aborts the owning tool call instead of restoring the wait from persistence.
-- **`host.describe.version` is a placeholder** — it does not yet report the `apps/cli` package version.
-- **The assembly is fixed** — per-deployment plugin selection (user profile, log sinks, alternative persistence) has a documented home here but no configuration surface yet.

# @deepseek-ai/dsh-host-webserver
-Web-shape HTTP carrier: a `node:http` server routing `/api/*` to an injected fetch-shaped handler (node:http ↔ WHATWG bridge with SSE streamed out chunk by chunk) and everything else to static file serving with the step1-locked semantics — traversal outside the dist root is 403, any miss falls back to `index.html` with HTTP 200 (SPA routing), unknown extensions ship as octet-stream, non-GET/HEAD is 405.
+Plain HTTP route-registration plugin (default-exported `WebServerService`, config `{host, port, distIndex}`): a `node:http` server that listens on activation and provides `ctx.webServer` — `register(route)` adds a named `exact`/`prefix` route (duplicate `(kind, path)` throws: route patterns are a composition-level contract, so a collision is a misconfiguration; the returned disposer removes the route), `tapIndex(transform)` adds an index.html transform applied in registration order, and `port` reads the listening port (the OS-assigned value when `port` is 0). The match order is fixed — exact over the whole table, then longest prefix, then the static dist fallback with the locked semantics: traversal outside the dist root is 403, any miss falls back to `index.html` with HTTP 200 (SPA routing), unknown extensions ship as octet-stream, non-GET/HEAD is 405. Registration order carries no request-facing semantics.
-The package has zero workspace dependencies on purpose: the handler arrives by structural typing (`{ fetch: typeof fetch }`), so `webserver ← runtime` is a runtime injection relationship, never a package dependency. Callers supply both the bind `host` and `port`; port `0` requests an OS-assigned port and the running handle reports the assigned value. `dsh web` defaults to `127.0.0.1` and accepts `--host 0.0.0.0` for deliberate network access. Web (browser) shape only — Electron loads dist over `file://` and carries fetch over an IPC bridge, not this server. This package never prints; the URL line belongs to the shell.
+The package knows no harness concepts: the `/api` bridge is the connection plugin's route, plugin bundles and the HMR event stream are the modules/hmr plugins' routes. `host` accepts only `127.0.0.1` (default posture) and `0.0.0.0` (deliberate network exposure); `distIndex` is an assembly fact the composing app resolves and injects, never self-resolved (dist location is workspace knowledge of the app). Web (browser) shape only — Electron loads dist over `file://` and carries fetch over an IPC bridge, not this server. This package never prints; the URL line belongs to the shell.
-Client-disconnect detection hangs off the **response** `close` event, not the request: since Node 16, `IncomingMessage` `close` fires as soon as the request body is consumed (immediately for a bodyless GET), which would abort every SSE stream right after open. `RunningWebServer.close()` pairs `close()` with `closeAllConnections()` because SSE connections never end on their own.
+A listen failure (EADDRINUSE…) throws out of activation — a FAILED fiber the boot's fail-loud sweep reports. A request whose handling throws (a malformed %-escape hitting `decodeURIComponent`, a client dropping mid-body) is answered 400 — or the socket destroyed when headers are already out — and logged as a warning; it never exits the process. Disposal pairs `close()` with `closeAllConnections()` because held-open responses (SSE) never end on their own.
-A request whose handling throws (a malformed %-escape hitting `decodeURIComponent`, a client dropping mid-body) is answered 400 — or the socket destroyed when headers are already out — and reported to `onError`; it never becomes a process-killing unhandled rejection.
+In development, the client-plugin registry synchronously captures each built bundle's stat baseline before it returns, then polls those baselines and re-hashes changed content. Each rescan stages its candidate table, graph, and watch map before publishing them, so a baseline failure preserves the prior graph. An immediate rebuild therefore cannot disappear into an asynchronously established watch baseline; a rename window marks the path dirty, retains the last successful baseline, and forces a re-hash when the bundle reappears even with identical metadata.
## Model Experience
-None, as the package is a pure HTTP carrier between the browser and the injected API handler; nothing here reaches a model request.

Provider-specific error text distinguishes terminal `QUOTA` from transient `RATE_LIMIT`, while text and usage signals evaluated against the resolved model's context window normalize overflow to `CONTEXT_WINDOW_EXCEEDED`.

- pi-ai folds reasoning tokens into output usage; there is no separate reasoning count to map.
- `GenerateOptions.stop` is rejected with `UNSUPPORTED_OPTION` because pi-ai's common streaming surface cannot guarantee it across providers.

+The default policy permits two retries for `EMPTY_RESPONSE`, `RATE_LIMIT`, `SERVER`, `TIMEOUT`, and `TRANSPORT`, using bounded exponential backoff from 500 ms to 10 seconds with 10 percent jitter. `EMPTY_RESPONSE` is the adapters' classification of a degenerate provider completion (a terminal stop with zero content blocks); the attempt produced nothing durable, so repeating it is safe. Delay bounds must fit Node's supported timer range. A valid `providerRetryAfterMs` replaces local backoff when it is within the configured cap; an over-cap instruction delegates to the next recovery policy instead.
Before waiting, the plugin appends a non-surface `llm/retry` event with the failure and scheduled delay. Cancellation and plugin disposal abort the wait; disposal drains the plugin's active backoffs, and a callback captured before disposal fails closed if invoked afterward.

- `errorChain(value)` — renders a thrown value with its full `cause` chain and AggregateError members for diagnostic surfaces (UI notices, logger lines, durable `turn/end` messages), so transport wrappers like undici's `TypeError: fetch failed` surface the underlying `ECONNREFUSED`/DNS/TLS detail instead of masking it. Rendering only — route on `code`, never by parsing the result.
- `CONTEXT_WINDOW_EXCEEDED_CODE` — the provider-neutral code both DeepSeek adapters use when a request exceeds the model context window, regardless of thrown-HTTP versus in-band finish delivery. `isContextWindowExceededError(detail)` is their shared conservative classifier for OpenAI-compatible provider detail.
- `QUOTA_EXCEEDED_CODE` — the non-transient provider-neutral code for exhausted account quota, balance, credits, budget, or usage limits. `isQuotaExceededError(detail)` keeps those failures distinct from request-rate limits.
+- `EMPTY_RESPONSE_CODE` — the provider-neutral code both adapters use for a degenerate provider completion: a terminal `stop` that carried no content blocks at all. Classified as an error finish (not a successful empty message) because the attempt produced nothing durable; `dsh-llm-retry` retries it by default.

-Local `node-pty` backend for `ctx.pty`. It starts an interactive shell under the shared `ctx.sandboxPolicy`, strips credential-shaped ambient environment variables, retains bounded line-oriented output, detects readiness, and tears down the captured process tree rooted at the `node-pty` child.
+Local Linux/macOS `node-pty` backend for `ctx.pty`; loading it on another platform fails as unsupported. It starts an interactive shell under the shared `ctx.sandboxPolicy`, strips credential-shaped ambient environment variables, retains bounded line-oriented output, detects readiness, and tears down the captured process tree rooted at the `node-pty` child.
## Plugin (`pty-local`)
The plugin injects `pty`, `sandbox`, and `sandboxPolicy`, then registers the configured backend type (`shell`). `danger-full-access` starts the shell directly; confined modes wrap the exact shell argv through `ctx.sandbox`. The effective session mode is resolved at spawn. A change to a different effective mode is rejected before its `sandbox/mode` event commits while that owner has an open PTY or a spawn in progress; the fence is attached to the exact owner and therefore outlives a local-provider reload that retains existing sessions. Wait for creation to settle and close the sessions before changing modes, so a terminal opened with wider access cannot survive a downgrade.
-Linux readiness combines a foreground-verified private bash prompt marker, foreground-process-group syscall inspection, silence fallback, and absolute timeout. macOS uses the verified prompt marker plus silence/timeout because it has no `/proc` syscall surface. A marker is not ready until printable prompt text arrives, including when the OSC marker and `PS1` are split across data callbacks. Unrecognized or unreadable process state is never a positive exact-idle signal. During unpublished startup, a fallback requires observed output; zero-output silence cannot publish an empty session, and timeout rejects the spawn. Cancellation closes the unpublished shell and rejects with the caller's exact abort reason even when its foreground process group is not observable yet; if that close fails, `PtyBackendCleanupError` separately preserves the cleanup failure for registry disposal. Incomplete terminal-control sequences are bounded by `maxReadBytes` and discarded through their terminator after crossing that limit; a trailing carriage return is carried across callbacks so split CRLF becomes one newline.
+Linux readiness combines a foreground-verified private bash prompt marker, foreground-process-group syscall inspection, silence fallback, and absolute timeout. macOS uses the verified prompt marker plus silence/timeout because it has no `/proc` syscall surface. A marker is not ready until printable prompt text arrives, including when the OSC marker and `PS1` are split across data callbacks; when bash prints the marker before the kernel publishes its return to the foreground process group, polling retains the candidate through one final poll after the ordinary silence bound so a coincident handoff can win. An interactive child that inherits `PROMPT_COMMAND` therefore cannot suppress inferred-idle readiness until the absolute timeout. Unrecognized or unreadable process state is never a positive exact-idle signal. During unpublished startup, a fallback requires observed output; zero-output silence cannot publish an empty session, and timeout rejects the spawn. Cancellation closes the unpublished shell and rejects with the caller's exact abort reason even when its foreground process group is not observable yet; if that close fails, `PtyBackendCleanupError` separately preserves the cleanup failure for registry disposal. Incomplete terminal-control sequences are bounded by `maxReadBytes` and discarded through their terminator after crossing that limit; a trailing carriage return is carried across callbacks so split CRLF becomes one newline.
Send cancellation resolves the current foreground process group and delivers a real `SIGINT`; it never emulates interruption by writing `\x03`, so raw-mode programs remain cancellable. Close sends `SIGTERM` to descendants, waits, then sends `SIGKILL` to the union of captured survivors and newly scanned descendants so reparenting cannot hide a process from teardown. It verifies that every retained identity is gone or, on Linux, a non-executing zombie before stopping the shell; zombie entries are quiescent and are reaped as the shell exits. A survivor failure does not cache a permanently rejected close; a later close retries the teardown.

- The first logical line is the immutable `SessionHeader` tagged `{ type: 'session', version, id, cwd?, createdAt, parentSession?, seedLength?, delegationDepth }`. `delegationDepth` is required on disk and is `0` for a top-level session; a missing or invalid value rejects the log. Every subsequent logical line is one storage record; `assistant/chunk` events are never dropped, and `seq` stays contiguous across the decoded log (`events[i].seq === i`).
- A storage record is a `SessionEvent` JSON verbatim, or — written only under `packChunks` — a **packed chunk row** (`text-chunks` / `reasoning-chunks` / `tool-call-chunks`; bare slash-less tags like the header's `session`, so row tags cannot be confused with event types): one line holding a run of ≥3 consecutive same-block `assistant/chunk` delta events, `seq0`/`time0` plus per-member `dt` gaps reconstructing every member's `seq`/`time` exactly. The lossless codec lives in `@deepseek-ai/dsh-session` (`packChunkRuns`/`decodeStorageRecord`) and whitelists exact shapes — anything unrecognized stores verbatim. Reading is layout-blind: `load` always decodes rows, so packed, unpacked, and mixed files load identically.
-- Session ids are unvalidated branded strings, so they are injectively escaped to a single safe path segment before use (no traversal, no collision).
+- The project directory keeps the normalized cwd readable for navigation and is bounded for filesystem component limits. Separator replacement and truncation are intentionally lossy, so cwd strings that normalize alike share a project directory; session ids still select distinct session directories. On a case-insensitive filesystem, identity validation accepts an alternate path spelling only when filesystem canonicalization resolves both spellings to the same transcript. The configured root remains deployment-controlled: it may be project-local, shared, temporary, or centralized. The [project-session directory decision](../../../.agents/notes/implemented/architecture/2026-07-24-project-session-directories.md) records this tradeoff.

## Physical encoding
The default artifact is a standard concatenation of independent [Zstandard frames](../../../.agents/notes/implemented/architecture/2026-07-19-zstandard-jsonl-session-logs.md): one checksummed frame containing only the header line, followed by one checksummed frame per durable append batch. The backend uses Node's built-in Zstandard API with its default compression level and exposes no level knob. Listing reads and validates only the header frame. `compression: 'none'` keeps the same logical lines in the original raw representation.

+A root belongs to one encoding. Startup discovery and targeted lookup reject the opposite suffix with an error naming the incompatible artifact and instructing the caller to select the matching mode or a separate root. Flat `<project>/<id>.jsonl*` artifacts are also rejected instead of ignored. There is no migration, mixed-root fallback, or dual write.
## Durability and crash semantics
-- **Bound storage identity.** Lookup requires one matching encoded filename across the cwd buckets, then verifies that the header id equals the requested id and that the header's id/cwd derive the selected path. Listing applies the same path check and rejects duplicate ids. Identity failures occur before repair or append.
+- **Bound storage identity.** Lookup requires one matching session directory across the readable project directories, then verifies that the header id equals the requested id and that the header's id/cwd derive the selected transcript path. Listing applies the same path check and rejects duplicate ids. Identity failures occur before repair or append.
- **Lazy materialization.** `create(meta)` writes nothing; on the first `append`, the backend writes and `fsync`s the encoded header and first batch in a temporary file. POSIX publishes it without overwrite via a hard link and `fsync`s the parent directory. Windows publishes it without overwrite via `MoveFileExW(..., MOVEFILE_WRITE_THROUGH)` and creates missing directories through the same write-through pattern. A created-but-never-appended session leaves nothing on disk and is absent from `list`.
- **Append-only.** Flushed events are never rewritten. Subsequent raw batches append lines; compressed batches append one frame. Both paths `fsync`, and a caught write or sync failure rolls the file back to its prior byte length.
- **Crash recovery — preserve valid tail work.** `load` validates every complete compressed frame and scans their decompressed JSONL. If the last frame is structurally incomplete, the reader keeps its complete decoded records, truncates from that frame's start, and re-encodes those records with the synthetic tool, step, and turn closers required by the shared [persistence contract](../../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.md). Raw mode truncates from its first incomplete line. A checksum/decompression failure in a complete frame, or a defect at or before the last committed `turn/end`, is corruption and rejects.
- **Non-mutating inspection.** `inspect()` returns the detached valid prefix without truncating an incomplete tail or closing an interrupted turn, and leaves the lightweight revision unchanged.
- **Contiguous-seq.** `append` rejects a batch whose first `seq` does not continue the stored log, and rejects non-JSON-serializable `event.data` naming the offending event type.
-- **Lightweight revisions.** `listSnapshots()` identifies a log by its device, inode, size, and nanosecond timestamps, avoiding a full-log parse while changing after append, repair, replacement, or store changes.
+- **Lightweight revisions.** `listSnapshots(signal?)` identifies a log by its device, inode, size, and nanosecond timestamps, avoiding a full-log parse while changing after append, repair, replacement, or store changes. It forwards the exact signal through artifact discovery and checks cancellation around every `stat`; because filesystem `stat` is not interruptible, cancellation waits for the active call to settle, then rejects without starting another.

## Known Limitations and Deferred Work
- **Only the configured encoding and current `SESSION_FORMAT_VERSION` (v0) load** — changing compression requires a separate/fresh root or selecting the legacy raw mode; the pre-release format has no migration.
+- **The flat-file storage layout does not load** — use a separate root or move pre-release artifacts into the project/session directory layout before loading.
- **Compressed files are not directly line-readable** — use the backend to load them, or select `compression: 'none'` before writing a fresh root when text fixtures or external line readers are required.
- **Nothing deletes session files** — logs accumulate under `root` until removed externally (the seam has no deletion surface).
- **One live writer per session** — append and repair are coordinated only inside the owning backend instance. Another backend instance or process must not write the same session until that owner reaches quiescent disposal; initial same-id publication remains collision-safe through the POSIX no-overwrite hard link or Windows write-through rename without replacement.

+The repository's Node range supports unflagged `node:sqlite`. The database enables foreign keys and uses the configured journal mode (`wal` by default; use a rollback mode where WAL shared-memory files are unsuitable). `PRAGMA application_id` identifies the canonical persistence database, and `PRAGMA user_version` stores its layout version. A fresh database must have no application identity or user-defined schema objects; initialization creates every table and stamps both pragmas in one transaction. Non-pristine unversioned databases, foreign application identities, and every non-current version reject before journal-mode mutation because this unreleased format has no migrations.
On filesystems with POSIX modes, the backend requests mode `0700` for missing directories and exclusively creates a missing database with mode `0600` before SQLite opens it; the process umask may further restrict both. New WAL, shared-memory, and persistent rollback-journal sidecars receive the database's resulting owner-only mode. Existing directories, database files, and sidecars keep their modes; filesystem setup errors other than an existing database fail initialization. These defaults prevent incidental exposure through a permissive process umask, but do not protect database confidentiality or integrity when another principal can replace the database entry in its parent directory.

- **Lazy materialization.** `create()` records intent in memory only — no row is written until the first `append`. A created-but-never-appended session has no `sessions` row, so it is absent from `list()` (which reports exactly the sessions that have a row).
- **Interrupted-turn close on load.** `load()` implements the shared [crash-recovery contract](../../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.md): preserve the valid interrupted turn, append its synthetic closing events in one transaction, and remove only a torn tail row. Committed parse errors or sequence gaps make the session unloadable. Because recovery mutates stored rows, the next append starts from a balanced log and accurate cursor.
- **Non-mutating inspection.** `inspect()` returns the detached valid row prefix without deleting a torn tail row or appending recovery closers, and leaves the lightweight revision unchanged.

When a live session emits `session/disposed`, the coordinator waits for its controller, serializes a final drain, then releases state owned by that exact `Session` object. Failed retirement leaves the controller in the live-session map, so backend teardown can retry it. Backend teardown stops event admission first, flushes every remaining controller, awaits per-id operations, and only then closes the storage handle.

The coordinator asserts the stored id and compares stored/live cwd before repair or live adoption. Its `inspect()` path validates and clones the prefix without calling `commitRepair` or publishing write state. The `tornMarker` is fully OPAQUE: the coordinator only tests `!== undefined` and round-trips it to `commitRepair`, never inspecting its value (the JSONL backend uses the byte offset to truncate to, the SQLite backend the seq to delete from). A third-party backend MAY implement the abstract service directly without the coordinator, but it must provide the same non-mutating inspection and trustworthy lightweight snapshot revisions.

## Tokenizer and limits
The index uses FTS5 `unicode61`. In the implementation experiment it supported the two-character query `AI` and produced an index about 2.1× smaller than the trigram alternative. The trade-off is token/phrase recall rather than arbitrary substring recall: `AI` does not match the token `BRAID`. Use `ctx.sessionQuery.filterEvents()` with a `text` clause when a literal whitespace-flexible substring scan is required. NUL is rejected in queries; reserved highlight markers and NUL in documents are normalized before indexing so presentation markers cannot collide with source text.
-Abort signals stop queued work and caller waits around asynchronous source observation. Node's synchronous `DatabaseSync` API cannot interrupt a MATCH statement already executing on the JavaScript thread; the signal is checked immediately before and after the serialized observation/reconciliation boundary.
+Abort signals stop queued work and flow unchanged through snapshot listing and non-mutating inspection. Once source work starts, the serialized state machine awaits that backend promise itself—even when a backend ignores cancellation—then checks the signal before starting any further listing, inspection, reconciliation, or query work. The caller therefore observes cancellation only after started backend work is quiescent, and a later search cannot enter the serializer while that cleanup is pending. Node's synchronous `DatabaseSync` API cannot interrupt a metadata or MATCH statement already executing on the JavaScript thread; signals are checked immediately before and after those non-preemptible calls.

-- `filterSessions(filters)` applies provider-independent session metadata and availability predicates to that same cloned logical corpus.
+- `listSessions(signal?)` reads current persistence metadata, merges live records with live precedence, and returns cloned records in deterministic newest-first order.
+- `readSession(sessionId)` returns one complete detached raw log after the same core replay validation used by resume; it never enters the session into the live store.
+- `filterSessions(filters, signal?)` applies provider-independent session metadata and availability predicates to that same cloned logical corpus.
- `filterEvents(sessionId, filters)` extracts first-party semantic documents and applies provider-independent metadata and literal-text predicates in ascending seq order.
-- `readTitle(sessionId)` loads one live-preferred or persisted log and folds its latest `session/title` event into a `SessionTitleSnapshot`; it returns `undefined` when the known session has no title.
+- `readTitleSnapshots(sessionIds, signal?)` resolves unique ids from one live-preferred corpus observation, passes cancellation through persisted listing and inspection, and returns ordered per-session settlements so one missing or malformed title source does not discard its peers. Each live source is folded directly, and each persisted worker folds to a detached header/title result and releases the full log before dequeuing another id. Cancellation rejects the whole batch. `readTitleSnapshot(sessionId, signal?)` is the one-observation view; `readTitle(sessionId, signal?)` returns only its optional folded `session/title`.
- `listEvents(sessionId)` loads the live-preferred raw log and classifies each event as `current`, `shadowed`, or `log-only` with the shared `dsh-session` surface fold.
- `readSurface(sessionId)` returns one cloned header, raw-log capture boundary, and the complete folded current surface in model-history order. A live session wins over persistence; compaction is observed before or after its replacement append, never as a synthetic mixture.
-- `readEvent(request)` returns a cloned header, the full target event, and a bounded raw-seq window. `before` and `after` default to zero and may not exceed `readWindowMax`.
-- `traceSession(sessionId)` reads the corpus once and returns immediate-to-outward ancestors plus deterministic recursive descendant trees. `complete: false` identifies the first missing parent; a target-connected cycle fails with `SESSION_QUERY_INVALID_LINEAGE`.
-- `traceEvent(request)` loads the logical log once and returns direct positional replacements and direct logged provenance. `replacementChain` follows positional replacers to the final replacement; provenance links remain non-transitive.

A title read, event trace, or event read targeting a known live session does not consult persistence, so durable backend health cannot make current in-memory state unreadable. Persisted title and event operations list before loading and reject a metadata mismatch rather than combining inconsistent observations. Lineage-trace cancellation is passed to persisted listing; event-trace and event-read cancellation is passed to persisted listing and inspection. Each waits for the started backend call to settle, then rejects with the signal's exact reason even when the backend ignored that signal. A pre-aborted known-live title read, event trace, or event read rejects before folding or snapshotting without consulting persistence. A batch title observation performs one metadata listing, inspects its unique persisted ids with at most `persistedInspectConcurrency` workers, and preserves each title's own observed header for downstream authorization. Cancellation starts no queued inspections and rejects only after already-started workers settle. `listSessions()` remains lightweight and does not load logs or index titles.

+# @deepseek-ai/dsh-tool-session-query
+
+Workspace-authorized model tools over `ctx.sessionQuery`. The opt-in package depends only on the unified interface and registers `session_search`, `session_event_search`, `session_trace`, `session_event_trace`, and `session_event_read`; shipped host compositions do not mount it by default.
+
+## Configuration
+
+| Key | Default | Meaning |
+|---|---:|---|
+| `maxSearchResults` | `100` | Maximum authorized non-self hits collected across internal provider pages |
+| `searchTimeoutMs` | `30000` | Cooperative deadline attached to both full-text search tools |
+
+The caller comes exclusively from `ToolExecution.exec.agent`. Cross-session access requires exact equality between the target and caller session `cwd` values; a caller without `cwd` can inspect only itself. Search never exposes provider cursors, offsets, page sizes, or a model-controlled limit. Because one search consumes generation-bound provider cursors internally, both search tools execute exclusively with sibling tool calls; the three exact trace/read tools opt into parallel execution. Every exact executor passes its unchanged execution signal through authorization and the service trace/read, so cancellation waits for cooperative persistence cleanup and retains the signal's exact reason. Timestamps at the tool boundary require an explicit `Z` or numeric offset and become inclusive epoch-millisecond filters.
+
+`session_search` always omits the caller session. Requested parent ids are deduplicated and checked against caller-workspace authority before FTS; only authorized ids reach the provider, while missing and cross-workspace guesses behave identically and the root marker remains independently ORed. A current-session `session_event_search` stops immediately before the step that invoked it, so the active assistant output and logged tool call cannot match themselves. Direct targets are authorized before trace, event, or title reads. Lineage output replaces unauthorized ancestor and descendant boundaries with markers that contain no hidden session id.
+
+Every trusted `ctx.sessionQuery` call crosses one model-boundary sanitizer. Caller cancellation is checked first and preserved exactly. Available corpus and provider diagnostics, including safely inspectable nested causes, are logged internally on a best-effort basis; unprintable failures use a fixed log placeholder. Diagnostic formatting and error classification are independently guarded, so an unprintable cause cannot escape or prevent a safely classified outer error, while unsafe classification or logging falls back to the fixed `SESSION_QUERY_TOOL_FAILED` code and message. Local argument-validation and authorization errors retain their precise tool-owned messages.
+
+The package deliberately performs no byte or character truncation and does not import a spill backend. Deployments that need bounded inline output mount `@deepseek-ai/dsh-spill-policy`, which can replace the rendered text after execution while retaining the complete result.
+
+## Model Experience
+
+### System prompt
+
+#### What the model sees
+
+The model receives one fixed prior-history guidance section.
+
+##### Prior-history guidance
+
+```markdown
+Use session_search to find relevant work from prior sessions, or session_event_search to search earlier events in one session. Search results are cursor-free and workspace-scoped. Follow a useful hit with session_trace, session_event_trace, or session_event_read when you need lineage, relationships, or exact data.
+```
+
+#### Token effect
+
+One fixed concise section is present on each request while the plugin is mounted.
+
+#### KV Cache effect
+
+Prefix-stable while the plugin and guidance text are unchanged.
+
+### Tool schemas
+
+#### What the model sees
+
+The model sees the generated [`session_search`, `session_event_search`, `session_trace`, `session_event_trace`, and `session_event_read` schemas](../../../docs/tool-catalog.md#deepseek-aidsh-tool-session-query). Search filters add fixed schema tokens, while cursors, workspace paths, output pagination, and model-controlled result limits remain absent.
+
+#### Token effect
+
+Five fixed read-only schemas are sent on each request while visible.
+
+#### KV Cache effect
+
+Prefix-stable while tool visibility and definitions are unchanged.
+
+### Tool results
+
+#### What the model sees
+
+Each successful call emits one plain-text block. Search results include titles and best-match excerpts; traces include all authorized relationships; event reads include unabridged target JSON. The generic spill policy may replace oversized inline text with its preview, opaque locator, and retrieval hint.
+
+#### Token effect
+
+Results are data-dependent and remain in logged tool history until compaction; `maxSearchResults` bounds search-hit count.
+
+#### KV Cache effect
+
+Append-only result text follows the reusable request prefix and does not invalidate earlier cache entries.
+
+## Known Limitations and Deferred Work
+
+- Search returns at most the deployment cap and asks the model to narrow its query when more matches exist; it offers no continuation token.
+- Workspace identity is conservative exact-string `cwd` equality, so symlink-equivalent paths do not share authority.
+- Custom compositions without the generic spill policy accept complete trace and event payloads inline.

+# storage/ — non-session storage family
+
+The storage family persists everything that is not a session event log: a hub where named backends and typed data forms meet. Design record: [domain KV storage Agent Note](../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.zh.md).
+
+| Package | Role | ctx key |
+|---|---|---|
+| `storage/` | The hub: named backend registry + merge-extensible data-form mounts, backend facet vocabulary, shared conformance suite | `ctx.storage` |
+| `storage-json/` | JSON backend: one human-readable file per unit, atomic whole-file rewrite | registers backend `json` |
+| `storage-sqlite/` | SQLite backend: one database hosting all routed units, document-per-row | registers backend `sqlite` |
+| `domain/` | Domain data form: zod-validated records, per-domain write chain, `domain/changed` events, backend routing by configuration | `ctx.storageDomain` + `ctx.storage.domain` |
+
+Backends own one medium each and expose data-shape **facets** (`kv` today; an append-log facet is reserved for the future session-backend migration). Each backend plugin publishes an internal lifecycle service after registration; the domain plugin injects every configured backend key before exposing its own service, so config-tree row order carries no startup semantics. Consumers never touch backends directly — they inject `storageDomain` and open declared domains through it.

+# @deepseek-ai/dsh-storage-domain
+
+Domain data form for the DeepSeek Harness storage hub: exposes the injectable `ctx.storageDomain` service and the matching `ctx.storage.domain` projection after every configured backend is registered. A domain is declared once with `defineDomain` (zod record schemas, `z.infer`-derived types), opened through `DomainFacility.open`, and served from authoritative in-memory state — reads are synchronous, writes serialize on one per-domain chain, reach durability on the routed backend first, then update memory and emit `domain/changed`. The opening consumer owns the handle's lifecycle and releases it with `Domain.close()` (idempotent; typically its own `ctx.effect` disposer); domains still open when the plugin unmounts are closed by the facility.
+
+Design rationale, open semantics, and the storage/domain layer split live in the [Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.zh.md).
+
+## Configuration
+
+| key | meaning |
+| --- | --- |
+| `backend` | Default backend name for every domain (required; no universally correct medium exists). |
+| `routes` | Per-domain overrides: domain name → backend name. |
+
+## Model Experience
+
+### Durable domain state
+
+#### What the model sees
+
+Nothing. The package registers no tools, injects no prompts, and appends no session events; it stores non-session data (workspace records, future session sidecars) behind `ctx.storageDomain` and emits only the in-process `domain/changed` event, which reaches a model only if a consumer package renders it through its own documented surface.
+
+#### Token effect
+
+Zero. No text from this package enters any model request.
+
+#### KV Cache effect
+
+Independent: domain reads and writes never touch request prefixes, so nothing here can invalidate provider cache reuse.
+
+## Known Limitations and Deferred Work
+
+- **Single-process change visibility** — `domain/changed` is an in-process event; a second host process or a reconnecting GUI observes no changes until the cross-process revision pattern deferred in the Agent Note lands.
+- **No cross-table transactions, secondary indexes, or multi-segment keys** — each write touches one record; triggers and rework points for these extensions are tabled in the Agent Note's deferred-work list.

+# @deepseek-ai/dsh-storage-json
+
+JSON backend for the [storage hub](../storage/README.md): one human-readable `<unit>.json` file per unit under a configured root, registered as backend `json`. Design: [domain KV storage Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.zh.md).
+
+## Model
+
+- The in-memory unit state is authoritative; every write primitive republishes the whole file via temp-write + fsync + atomic `rename()` replace. A unit file is always the complete current net state — legibility is this backend's reason to exist; scale is the SQLite backend's job.
+- A missing file opens as an empty unit and materializes on the first write. A foreign or unparsable file rejects with `malformed-medium`; a stored version differing from the descriptor rejects with `version-mismatch` (no migration, pre-release stance).
+- Write ordering across calls belongs to the caller (the domain layer's write chain); each single call is atomic and durable once resolved.
+
+## Config
+
+| Key | Type | Default | Meaning |
+| --- | --- | --- | --- |
+| `root` | string | required — no default (a cwd fallback would scatter files) | Directory holding unit files; created `0o700` on demand |
+
+## Model Experience
+
+### Stored domain records
+
+#### What the model sees
+
+Nothing. This backend contributes no prompt, tool, or schema; it persists non-session domain data behind `ctx.storage` for host-side consumers only.
+
+#### Token effect
+
+Zero live-request tokens.
+
+#### KV Cache effect
+
+None — the backend never touches live request prefixes.
+
+## Known Limitations and Deferred Work
+
+- Windows durability relies on libuv's `rename()` (`MoveFileExW` with replacement) without an explicit write-through flag; the session-log backend's stricter Win32 write-through publish helper is planned to move down here when the append-log facet lands (see the Agent Note's migration section).
+- No cross-process write locking: two processes writing the same root can interleave whole-file replacements (last write wins). Single-host-process deployments are the current consumer; the multi-process story is deferred per the Agent Note's out-of-scope table.

+# @deepseek-ai/dsh-storage-sqlite
+
+SQLite backend for the [storage hub](../storage/README.md): registers as backend `sqlite`, serving the `kv` facet over one `node:sqlite` database file (or `:memory:`). Design and trade-offs: [domain KV storage Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.zh.md).
+
+## Storage model
+
+Document-per-row: each unit table becomes a physical `"u_<unit>_<table>" (key TEXT PRIMARY KEY, value TEXT)` STRICT table whose `value` is the record's JSON text, so one key updates one row (the reason to route a high-churn domain here instead of the JSON backend). Unit identity lives in two metadata tables — `units` stamps each unit's format version at first open and rejects a differing descriptor with `version-mismatch`; `unit_globals` holds each unit's global singleton row. The physical layout version lives in `PRAGMA user_version`; any other stamped value rejects (unreleased format, no migrations). Unit and table names are validated against the hub's `UNIT_NAME_RE` before they reach DDL, so no external input is ever interpolated into SQL identifiers.
+
+Every write primitive is a single prepared statement — SQLite's per-statement atomicity satisfies the KV contract without explicit transactions, and write ordering stays the caller's responsibility (the domain layer's write chain). Missing directories and database files are created owner-only (`0o700`/`0o600`), matching the session-persistence SQLite backend, whose open sequence this package copies verbatim until the planned media-layer extraction.
+
+## Configuration (schemastery)
+
+```ts
+interface Config {
+ path: string // SQLite database file path, or ':memory:' for an in-process DB
+ journalMode?: 'wal' | 'delete' | 'truncate' | 'persist' // journal_mode pragma; default 'wal'
+}
+```
+
+## Model Experience
+
+### Stored domain records
+
+#### What the model sees
+
+Nothing. This backend contributes no prompt, tool, or schema; it persists non-session domain data (workspace records, future session sidecar metadata) behind `ctx.storage` for host-side consumers only.
+
+#### Token effect
+
+Zero live-request tokens.
+
+#### KV Cache effect
+
+None — the backend never touches live request prefixes.
+
+## Known Limitations and Deferred Work
+
+- **`DatabaseSync` is synchronous** — each write blocks the event loop for its (single-statement) duration; acceptable at domain-data scale.
+- **No busy-wait or retry policy** — another connection holding a write transaction rejects the operation immediately; multi-process write protection is on the design's future-work list.
+- **Only the current `STORAGE_SQLITE_SCHEMA_VERSION` opens** — any other stamped version is rejected rather than migrated (pre-release stance).
+- **`openDatabase` duplicates the session-persistence SQLite open sequence** — extraction into a shared media layer is deferred to the planned session-backend migration (see the Agent Note's reuse audit).

+# @deepseek-ai/dsh-storage
+
+Storage hub (`ctx.storage`) for non-session data: a named backend registry plus mounted data-form facilities. The hub performs no IO itself — backends own media, data forms own semantics. Design and trade-offs: [domain KV storage Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.zh.md).
+
+## Shape
+
+- `ctx.storage.backend` — name → backend table. Multiple backends stay mounted side by side (`json`, `sqlite`); which backend serves a consumer is that consumer's configuration (the domain layer's route table), never a hub-global choice. `register()` returns the disposer; duplicate names and unknown lookups fail loud.
+- `ctx.storage.mount(form, facility)` / `ctx.storage.form(form)` — data-form mounting. `StorageForms` is merge-extensible; the domain layer merges `domain` and is reached as `ctx.storage.domain`.
+- A backend owns one medium (file-tree root, database file) and exposes optional data-shape **facets** — `kv` today; an append-log facet is reserved for the future session-backend migration. `src/backend.ts` is the normative contract text; `tests/contract.ts` exports the shared conformance suite every backend runs.
+
+## Packages in this group
+
+| Package | Role |
+| --- | --- |
+| `dsh-storage` | The hub service + backend vocabulary + shared conformance suite |
+| `dsh-storage-json` | JSON backend: one unit per human-readable file, atomic whole-file rewrite |
+| `dsh-storage-sqlite` | SQLite backend: one database hosting all routed units, document-per-row |
+| `dsh-storage-domain` | Domain data form (`ctx.storage.domain`): typed schemas, write chain, change events |
+
+## Model Experience
+
+### Backend and form registrations
+
+#### What the model sees
+
+Nothing. `ctx.storage` is a host-side registration table; the hub registers no tools, injects no prompts, and writes no session events.
+
+#### Token effect
+
+Zero direct tokens on every request.
+
+#### KV Cache effect
+
+Independent of live requests: the hub never touches a request prefix, so it cannot invalidate provider cache reuse.
+
+## Known Limitations and Deferred Work
+
+- **`kv` is the only data shape** — the append-log facet the future session-backend migration needs is reserved in the design note but not yet defined; backends currently have exactly one facet to implement.
+- **Forms resolve lazily** — reading `ctx.storage.domain` before the domain plugin mounts throws `form-not-mounted`; assemblies order plugins accordingly (misconfiguration fails loud rather than silently deferring).

@@ -6,7 +6,7 @@ Four layers, importable separately:
- **`launchAcpTestAgent` (launcher)** — boots a source agent under tsx or a built `lib` agent under plain Node from a supplied cwd, connects the SDK client over a raw-byte stdout tee, collects session updates and stderr, surfaces asynchronous spawn failures through startup, fails closed on unhandled permission requests, and owns graceful or signalled shutdown. Shutdown waits for process exit, inherited stdio closure, and ACP parser exhaustion before resolving or propagating a child error, so captures are complete and callers can remove owned paths after either outcome. When Windows accepts forced termination but publishes its exit marker asynchronously, shutdown gives that marker a bounded grace before treating fallback refusal as a second failure. Snapshot and ordinary e2e suites share this process boundary; a test supplies only agent paths, cwd, environment overrides, and any permission policy.
- **`runScenario` (harness)** — drives ACP JSON-RPC stdio from a deterministic `input.json` script through the launcher, tees raw stdout for the expected-output and purity checks, and harvests every persisted raw JSONL session log (parent and subagent children, primary-first) after graceful stdin EOF. `AgentUnderTest` supplies absolute `binScript`, optional `libBinScript`, `configPath`, and `tsconfigPath` paths because the subprocess cwd is outside the repo; `workspaceParent` may move the generated child cwd from the platform temp directory when that grant is itself under test. Startup failures preserve captured agent stderr in the rejected diagnostic.
-- **Normalizers** — pure functions turning the two captured surfaces into stable text: `normalizeStdout` (JSON-RPC ids → first-seen sequence; UUIDs/cwd → tokens; cwd-rooted separators selected as canonical `/` or host-native; `session_info_update.updatedAt` → `{{updatedAt}}`; doubles as the stdout-purity check), `normalizeSessionLog` (times zeroed, `seq` kept, the same cwd-path policy), `scrubSystemPrompts` (prompt text → `{{system}}`), `scrubToolSchemas` (schema bulk → `{{tools}}`), and `scrubRequestHeaders` (all header bulk → `{{system}}`/`{{tools}}`/`{{messagePrefix}}` outside each pin, structure kept — [pinned-header Agent Note](../../../.agents/notes/implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).
+- **Normalizers** — pure functions turning the two captured surfaces into stable text: `normalizeStdout` (JSON-RPC ids → first-seen sequence; UUIDs and every native/JavaScript filesystem spelling of the generated cwd → tokens, longest-first; cwd-rooted separators selected as canonical `/` or host-native; doubles as the stdout-purity check), `normalizeSessionLog` (times zeroed, `seq` kept, the same cwd-path policy), `scrubSystemPrompts` (prompt text → `{{system}}`), `scrubToolSchemas` (schema bulk → `{{tools}}`), and `scrubRequestHeaders` (all header bulk → `{{system}}`/`{{tools}}`/`{{messagePrefix}}` outside each pin, structure kept — [pinned-header Agent Note](../../../.agents/notes/implemented/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).
- **`defineAcpSnapshotSuite` (factory)** — registers the whole describe/it tree for a scenario table: per-scenario expected-output and re-persisted-log comparisons, record/refresh fixture write-back, rejection of structured `UNKNOWN_TOOL` results, the per-header-class pin (`system-prompt.expected.md` plus `tool-schemas.expected.json`) with its live uniformity guard, and the fixture guard block (no orphan scenario dirs, required files present, exactly one pin per class, every JSONL prompt/schema-scrubbed, non-pinning fixtures fully header-scrubbed). Refresh expands packed timing envelopes before aligning existing volatile event times, so switching between packed and unpacked layouts cannot shift later records; fresh chunk-fragment arrays remain authoritative. A newly inserted `session/title` receives its preceding event's time so feature-driven insertions do not churn the remainder of a fixture. Each scenario directory's `session.jsonl` plus contiguous `session.<n>.jsonl` siblings are the ordered primary/child inventory; the scenario table does not duplicate their count.

Session config options are scriptable too: the `setConfigOption` step switches a knob over `session/set_config_option`, and `setConfigOptionExpectError` asserts the bridge rejects an unknown id or out-of-vocabulary value (the error frame stays in the transcript).

+# `@deepseek-ai/dsh-llm-mock-server`
+
+A scriptable OpenAI-compatible HTTP/SSE server for exercising real LLM adapters, the agent loop, and recovery policy without a provider key. It accepts `POST /chat/completions` and `POST /v1/chat/completions`; each accepted request consumes one configured behavior in arrival order. Invalid methods, paths, bearer tokens, and JSON do not consume the script.
+
+The library entry exports `startMockLlmServer(options)`, behavior and telemetry types, the default random stress weights, the accepted Node timer bound, and a running handle with the bound `baseURL`, generated or configured `randomSeed`, captured requests, and idempotent `close()`. Closing force-terminates stalled connections.
+
+## Standalone use
+
+Run the source entry from this repository:
+
+```sh
+pnpm run mock:llm -- \
+ --port 8000 \
+ --api-key mock-key \
+ --sequence partial_disconnect,success \
+ --partial-text "discard this half"
+```
+
+Point the shipping DeepSeek adapter at the server; it appends `/chat/completions` to the configured base:
+
+```sh
+DEEPSEEK_BASE_URL=http://127.0.0.1:8000/v1 \
+DEEPSEEK_API_KEY=mock-key \
+pnpm run demo:headless "test provider recovery"
+```
+
+The built package also exposes `dsh-llm-mock-server`. Stdout is JSONL: a `ready` record carries the `/v1` base URL and random seed, followed by request/result records that name both the scripted behavior and the concrete selected behavior.
+
+## Behavior script
+
+`--sequence` is a comma-separated FIFO. Exhaustion returns a structured HTTP 500; `--repeat-last` explicitly reuses the last entry.
+
+| Behavior | Wire result |
+|---|---|
+| `connection_reset` | Destroy the socket before HTTP headers |
+| `stream_disconnect` | Send SSE headers, then reset before the first event |
+| `partial_disconnect` | Send text deltas, then reset the socket |
+| `stall` | Send SSE headers and remain idle until client/server cancellation |
+| `empty` | Send a valid content-less stop and `[DONE]` |
+| `empty_body` / `stream_eof` / `partial_eof` | End cleanly without the required `[DONE]` boundary |
+| `malformed_json` / `malformed_event` | Send invalid SSE JSON or an invalid provider chunk shape |
+| `rate_limit` / `server_error` / `service_unavailable` | Return retry-oriented 429/500/503 JSON errors |
+| `auth_error` / `invalid_request` / `context_overflow` / `quota_exceeded` | Return terminal or separately recovered provider errors |
+| `success` / `slow_success` / `reasoning_success` | Stream a complete text response, optionally delayed or preceded by reasoning |
+| `tool_call_success` / `max_tokens` | Complete with a tool call or `length` finish |
+| `wrong_content_type` | Send a valid SSE body under `application/json` |
+| `random` | Select a concrete request behavior from weighted seeded randomness |
+
+`connection_refused` is CLI-only and must be the first entry. It delays binding a caller-specified nonzero port, so requests during `--listen-delay-ms` receive a real TCP refusal; the remaining entries begin after the listener starts.
+
+## Random mode
+
+Use a repeating `random` entry for an open-ended mixed run:
+
+```sh
+pnpm run mock:llm -- \
+ --port 8000 \
+ --sequence random \
+ --repeat-last \
+ --seed 42 \
+ --random-weights 'success=60,slow_success=10,connection_reset=5,stream_disconnect=5,partial_disconnect=10,empty=5,server_error=5'
+```
+
+Omitting `--seed` generates one and prints it in the `ready` record. `--random-weights` accepts non-negative relative `behavior=weight` entries and requires at least one positive concrete behavior. The exported default is a success-heavy stress profile containing reset, disconnect, partial output, empty completion, stall, 429/5xx, clean truncation, and malformed JSON; it is test pressure, not an estimate of production incident frequency. `connection_refused` is excluded because a bound request handler cannot produce a true refusal.
+
+When random weights include `stall`, configure the client under test with a short stream-idle timeout so the scenario terminates promptly.
+
+## Timing and content controls
+
+The CLI exposes `--success-text`, `--partial-text`, `--reasoning-text`, `--chunk-size`, `--chunk-delay-ms`, `--disconnect-delay-ms`, `--retry-after-ms`, `--request-id`, `--tool-name`, and `--tool-arguments`. Millisecond delays are bounded integers within Node's timer range; `retryAfterMs` must also be positive. The library accepts the same camel-case options. An optional exact `apiKey` validates `Authorization: Bearer <token>`; omission accepts any token.
+
+## Model Experience
+
+None, as this test server substitutes provider wire behavior without invoking a real model.
+
+#### KV Cache effect
+
+None; requests terminate locally and never reach a provider cache.
+
+## Known Limitations and Deferred Work
+
+- **Random weights model test pressure, not production incidence** — callers that want an environment-specific distribution must provide measured weights and record the emitted seed.
+- **Request scripts are arrival-ordered** — concurrent callers share one cursor, so deterministic per-session fault assignment requires separate server instances.
+- **True connection refusal is a listener lifecycle phase** — the CLI delay must overlap the client attempt; request-level random selection can only reset an accepted connection.

-A replay LLM plugin for keyless snapshot tests. It yields model streams reconstructed from a recorded **session JSONL** fixture, so a test can boot the real agent against a fixed model transcript with no API key. With `providers` configured it registers a replay-only adapter whose catalog is visible to clients such as ACP editors; without `providers` it installs the catch-all `llm/stream` waterfall used by tests that do not need discovery.
+A replay LLM plugin for keyless snapshot tests. It yields model streams reconstructed from a recorded **session JSONL** fixture, so a test can boot the real agent against a fixed model transcript with no API key. With `providers` configured it registers a replay-only adapter whose catalog is available to scenarios that exercise model discovery; without `providers` it installs the catch-all `llm/stream` waterfall used by tests that do not need discovery.
-Its consumers are the ACP snapshot harness in `examples/acp-agent` and the `stream-json` snapshot in `examples/headless-agent`; each loads this plugin in place of a real LLM adapter. Keeping derivation and replay here places that logic under the per-file 100% coverage gate on `packages/*/src`.
+Its consumers are the ACP, headless `stream-json`, and TUI snapshot suites plus the web browser e2e lane. Loader-driven suites mount this plugin in place of a real LLM adapter; the web lane installs it directly to retain the teardown consumption handle. Keeping derivation and replay here places that logic under the per-file 100% coverage gate on `packages/*/src`.
## How the fixture works
The fixture IS the persisted session log (`<scenario>/session.jsonl`). Its `assistant/chunk` events carry every `StreamChunk`, so grouping them by `(turn, step)` reconstructs each `stream()` call's chunk sequence (one model call per loop step). Recording is therefore "run the real agent once and harvest the `.jsonl`", done by the snapshot harness — this plugin does not record. A fixture may carry its `request/header` content tokenized to `{{system}}`/`{{tools}}` (the harness pins that content in one scenario and scrubs the rest); replay is indifferent — derivation reads only `assistant/chunk` events and the line-0 session header.
-Two failure modes are not reconstructable from `assistant/chunk` alone — a pure throw before any chunk (e.g. an HTTP 401, where the log holds only a `turn/end {error}` and no chunks) and a cancel/hang (timing, not chunk content). A scenario that needs those supplies an optional sidecar (`<scenario>/replay.override.json`: a `ReplayEntry[]`) that REPLACES the derived script.
+Two failure modes are not reconstructable from `assistant/chunk` alone — a pure throw before any chunk (e.g. an HTTP 401, where the log holds only a `turn/end {error}` and no chunks) and a cancel/hang (timing, not chunk content). A scenario that needs those supplies an optional sidecar (`<scenario>/replay.override.json`: a `ReplayEntry[]`) that REPLACES the derived script.

+- `installLlmReplay(ctx, config)` — install the configured replay adapter or catch-all `llm/stream` listener; returns a `ReplayHandle` (`dispose()` for HMR safety plus `assertConsumed()`, the teardown check that every recorded script bound to a live session and every bound cursor drained — turning a scenario that silently drove fewer model calls than recorded into a crisp diagnostic). Use this in tests to drive replay without the Loader or env vars.
- `loadSessionScripts(config)` — resolve the ordered `SessionScript[]` (primary + children) for a scenario, ready to bind to live sessions in first-call order.
- `loadReplayScript(config)` — resolve the `ReplayEntry[]` for the PRIMARY session only (sidecar override if present, else derived from the JSONL; fail-loud if the fixture is missing).
- `deriveReplayScript(events)` / `parseSessionLog(text)` / `parseSessionHeader(text)` — the pure helpers that turn a recorded session log into a script and read its header `id`/`createdAt`. A derived group must end in a `finish` chunk; a group without one is the fingerprint of a thrown `stream()` and must instead be expressed via an override sidecar.

-# @deepseek-ai/dsh-acp
-
-Agent Client Protocol bridge over JSON-RPC stdio. Editors can create or resume agents, stream their events, answer questions and approvals, and render tool calls. One connection supports multiple isolated sessions; Zed is the primary compatibility target.
-
-It is a **client-driver / UI plugin**, the structured analogue of the terminal `dsh-tui` channel — NOT a loop change and NOT a [capability seam](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md). It consumes the existing `agent/*` event taxonomy, the `dsh-agent` create/resume factory, and `dsh-session-persistence`.
-
-## Service / plugin
-
-`apply(ctx, config)` — wires an `AgentSideConnection` (from `@agentclientprotocol/sdk`) to `process.stdin`/`process.stdout` and implements the ACP `Agent` method surface.
-
-The plugin injects `agents`, [`commands`](../commands/README.md), `sessionPersistence`, `sessionQuery`, `tools`, `userInteraction`, `llm`, and `systemPrompt`, never the concrete loop. Persistence backs `session/load`; live-preferred session queries back `session/list`; the command registry backs slash discovery and direct dispatch; the LLM catalog backs model selection; prompt assembly keeps model variables aligned with routing; tool definitions own presentation; user interaction maps agent questions to ACP forms.
-
-### Config
-
-| Key | Default | Meaning |
-|---|---|---|
-| `provider` | — | Initial provider route for created agents (must have a registered adapter). |
-| `model` | — | Initial model id for created agents. |
-
-(No persona key: `dsh-system-prompt`'s own `persona` config supplies the global default section, so ACP-created agents render it without the bridge carrying prompt text. An agent-scoped same-name section may still shadow that default.)
-
-The `initialize` handshake reports a fixed server identity (`agentInfo: { name: 'deepseek-harness-acp', version: '0.0.1' }`) — branding is a literal at the `initialize` site, not config.
-
-## ACP method mapping
-
-| ACP method | Harness seam | Notes |
-|---|---|---|
-| `initialize` | static | negotiate `protocolVersion`; advertise baseline prompt capabilities (`text`, plus `resource_link` rendered as text), `loadSession: true`, and `sessionCapabilities.list` |
-| `session/new` | `ctx.agents.create({ sessionId, meta:{cwd} })` | creates a new session/agent; N concurrent sessions are allowed, keyed by id; advertises the effective command snapshot; `cwd` must be absolute (it becomes the session's workspace — see Per-session cwd); non-empty `additionalDirectories` and `mcpServers` rejected |
-| `session/load` | `ctx.agents.resume(...)` | reserves the id, verifies the persisted cwd, resumes, replays user, assistant, tool, and title events, and re-advertises commands |
-| `session/list` | `ctx.sessionQuery` | returns live-preferred newest-first sessions with absolute cwd and optional folded title; supports exact normalized cwd filtering, returns no cursor, and rejects supplied cursors |
-| `session/prompt` | `ctx.commands.execute()` or `agent.send()` | a flattened prompt beginning with `/` stays in the direct command plane; ordinary prompts support ACP `text` and `resource_link`; `dsh-session:` links and inline mentions are snapshotted through optional `ctx.sessionReferences` before enqueue; unsupported content, unavailable reference capability, failed snapshots, and empty prompts are rejected; one request is in flight per session and settles on the owning turn's end, with an error turn rejecting the RPC |
-| `session/cancel` | command `AbortSignal` or `agent.cancel()` | aborts the exact direct command, or applies the queue-aware agent cancel and settles its prompt `cancelled`; one session never cancels another |
-| `session/update` | `session/event` | streams user replay, assistant text/reasoning, retry/failure attempt markers, tool render intents, and `session_info_update` title revisions |
-| `elicitation/create` | `ctx.userInteraction.ask()` | maps `ask_user_question` questions to ACP form elicitations; option descriptions are shown in enum titles, `multi_select` uses ACP array enums, optionless requests use a required `custom` field, and a non-empty custom answer overrides any selected choice |
-| `session/request_permission` | `approval/request` listener | answers one-shot allow/reject requests for bridge-owned calls; foreign or call-less requests delegate and fail closed if unanswered — see "Permission prompts" |
-| `session/set_config_option` | agent-scoped request target / `ctx.permission.set()` | per-session provider+model and permission-preset switching over [session config options](https://agentclientprotocol.com/protocol/session-config-options) — see "Session config options" |
-
-## Multi-session
-
-One id-keyed record map plus exact agent-object checks route every event, prompt, cancel, and approval to one session. Each session permits one in-flight prompt or reference-preparation operation; `session/cancel` aborts preparation before it can enqueue. Teardown drains all sessions in parallel. See the [multi-session Agent Note](../../../.agents/notes/implemented/feature/2026-06-14-acp-multi-session.md).
-
-## Human commands
-
-After `session/new` and `session/load`, the bridge emits ACP's full `available_commands_update` snapshot for that exact agent. A new session's server-generated id is introduced by the RPC response before its snapshot enters the connection write queue. A global or scoped registry change refreshes every live session from its independently resolved view, so clients replace rather than merge cached catalogs. Names omit the slash; descriptions and optional unstructured-input hints map directly to ACP `AvailableCommand`.
-
-ACP v1 permits a command prompt to carry additional content blocks. The bridge applies its ordinary lossless flattening for supported `text` and `resource_link` blocks, then dispatches when the result begins with `/`. Known commands execute without a model request. Unknown or malformed slash input returns a direct error instead of falling back to the model; prefix whitespace when literal slash-leading text must reach the model. Expected handler errors, thrown failures, and successful text stream as UI-only `agent_message_chunk` output and end the request; cancellation returns `cancelled`. See the [command Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-plugin-command-registration.md) and the [ACP v1 slash-command contract](https://agentclientprotocol.com/protocol/v1/slash-commands).
-
-## Session config options
-
-The bridge advertises a `model`-category select in `session/new` and `session/load` when the session has a complete target whose provider is registered. Values encode the complete provider/model pair, are grouped by provider when more than one group is available, and come from `ctx.llm.listProviders()` / `listModels()`. The configured or last-requested model is added when absent because catalogs are advisory and private adapters may accept unlisted ids. A selection changes only that ACP session. Agent-scoped prompt assembly snapshots the selected pair for one step, supplies matching `{{provider}}` / `{{model}}` variables, and the `agent/request` waterfall applies the same pair; a concurrent selection therefore takes effect on the next step instead of splitting prompt text from routing. The resulting request header is the durable record restored by `session/load`; a selection never used by a request remains in-memory only.
-
-When `ctx.permission` is composed, the bridge also advertises a `permission` select. Options come from the deployment's preset table; the current value comes from the session fold, with switch-away-only `custom` for unmatched knobs. `session/set_config_option` accepts advertised presets and writes both sandbox-mode and approval-policy events through `PermissionService.set()`. Open-turn switches append immediately; idle switches overlay responses and anchor at the next `agent/prompt-submit`, before request assembly. A crash before anchoring restores the durable fold. See the [model-catalog Agent Note](../../../.agents/notes/implemented/architecture/2026-07-15-llm-model-catalog-and-acp-selection.md), [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md), [`dsh-permission`](../permission/README.md), and [protocol matrix](acp-feature-support.md#6-session-modes--config-options--models).
-
-The shared [`ctx.tasks` runtime](../../tasks/tasks/) fences access to predictable task ids by the owning session; ACP sessions therefore cannot read or stop one another's background work.
-
-ACP updates are append-only, so `llm/retry` emits a visible separator that marks preceding partial model output discarded before the next attempt streams. A terminal model-request failure emits the same discarded-output warning; replay derives both markers from the durable events.
-
-A log-only `session/title` event maps to ACP `session_info_update` with `title` and the event timestamp as `updatedAt`. The same mapping runs for live events and `session/load` replay, so an asynchronously generated late title and a restored persisted title have one wire representation without entering model history.
-
-`session/list` returns the same latest folded title in standard `SessionInfo.title`. When `ctx.sessionReferences` is mounted, each listed item also carries `_meta["deepseek-harness/sessionReference"].uri`; a title-aware client can render `title ?? sessionId` in its `@` picker and submit that URI as a `resource_link` with the same display name. Sessions without cwd are omitted because ACP requires an absolute `SessionInfo.cwd` and the bridge cannot load them.
-
-## Per-session cwd
-
-`session/new` records the request's absolute cwd in the session header. Before constructing an agent, `session/load` uses persisted metadata to require an absolute request cwd that matches the stored one. Bash defaults to that workspace; an explicit relative workdir resolves against it, and multiple sessions may use different workspaces. `additionalDirectories` remains unsupported.
-
-## Tool-call presentation
-
-Tools return provider-neutral `generic`, `terminal`, or `diff` render intents from `presentCall()` and `presentResult()`. The bridge maps the discriminator to ACP without special-casing tool names and falls back to a generic card. Per-session call-id state supplies result events with their omitted name and arguments during live streaming and replay. File-card titles are relative to the session cwd and use the host separator, while location and diff paths remain raw so the editor opens the real file. See [`dsh-tools`](../../core/tools/README.md#tool-owned-ui-presentation).
-
-## Terminal card (capability-gated)
-
-When the client advertises `_meta.terminal_output`, terminal intents map to Zed's terminal info, output, and exit metadata. The bridge resolves relative cwd against the session and preserves the host filesystem separator, places the description before the terminal block, and omits result content because ACP updates replace call content. Other clients receive a generic card and bridge-derived fenced console fallback. Session creation snapshots the capability so call and result agree. The command still executes through the harness, not ACP terminal creation. See the [terminal-rendering Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-acp-terminal-and-tool-rendering.md) and [render-intent Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md).
-
-## Settle-exactly-once
-
-A prompt captures its owning turn and settles exactly once from the matching durable `turn/end`, even if presentation failed. Turn correlation excludes stale endings. Error turns reject with an ACP internal error; empty prompts reject before enqueue.
-
-## Permission prompts
-
-For a bridge-owned call, the [approval seam](../user-approval/README.md) maps `ask` to an editor prompt with one-shot allow/reject options. Foreign or call-less requests delegate; unknown choices never grant, cancellation stays cancellation, and transport failure becomes fail-closed unavailability. Whether a tool asks remains policy outside the bridge.
-
-## Disposal & disconnect
-
-Disposal and client disconnect share one memoized teardown. It cancels pending prompts and disposes all owned agent handles in parallel, waiting for loop exit and final flush before registry removal. Mid-turn teardown records `disposed`; `session/cancel` records `aborted`.
-
-## stdout is the protocol
-
-The JSON-RPC frames go on stdout, so this plugin MUST run in an example that loads **no stdout logger** (the console logger writes to stdout and would corrupt the frames). The guarantee is config-only — see `examples/acp-agent` (no console logger) and [ACP support risks](../../../.agents/notes/implemented/feature/2026-06-14-acp-agent-client-protocol.md#risks). A stderr exporter is fine for logging.
-
-## Running
-
-`pnpm --dir /path/to/deepseek-harness run demo:acp` boots `examples/acp-agent` (needs `DEEPSEEK_API_KEY`). Point an ACP client at it; for Zed, add to `agent_servers`:
-
-```json
-{
- "agent_servers": {
- "DeepSeek Harness": {
- "command": "pnpm",
- "args": ["--dir", "/path/to/deepseek-harness", "run", "demo:acp"]
- }
- }
-}
-```
-
-## Model Experience
-
-### User messages
-
-#### What the model sees
-
-Each ACP `session/prompt` becomes an agent user message: text passes through verbatim and each ordinary `resource_link` becomes exactly a leading newline, `[resource_link name=<JSON-string> uri=<JSON-string>]`, and a trailing newline. When `ctx.sessionReferences` is mounted, a `resource_link` whose URI uses `dsh-session:` or an inline canonical mention becomes readable `@label` text plus one durable untrusted snapshot context; without the capability it is rejected. Unsupported image, audio, and embedded-resource blocks are rejected rather than silently omitted.
-
-#### Token effect
-
-Prompt tokens are data-dependent and remain in that session's history until compaction. Concurrent ACP sessions keep separate contexts.
-
-#### KV Cache effect
-
-Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries.
-
-### Human commands
-
-#### What the model sees
-
-Nothing from command discovery, slash input, or command output. A command handler may separately mutate a durable domain whose later state affects model requests.
-
-#### Token effect
-
-Direct dispatch adds no model tokens and no session message. The mutated domain owns any later prompt or history cost.
-
-#### KV Cache effect
-
-Command discovery, dispatch, and direct output never enter a model request and do not affect its cache. A mutated domain owns any later cache effect.
-
-### Human answers and permission decisions
-
-#### What the model sees
-
-When optional consumers are loaded, ACP form answers become the exact JSON shape documented by `dsh-tool-ask-user`. Failures become `Error: ACP user questions must come from an agent-owned request`, `Error: ACP user question has no matching session`, `Error: ACP elicitation request failed`, `Error: ask_user_question was cancelled by the user`, `Error: ask_user_question returned no answer`, or `Error: ask_user_question was aborted before the user answered`. Permission decisions control whether another tool yields success or denial. ACP tool cards, terminal output, diffs, title updates, and other streamed session updates are UI-only.
-
-#### Token effect
-
-Answer, error, and denial text enters context only through the owning tool result; presentation metadata adds zero model tokens. A replacement `tool/result` still changes the model-facing session surface, but live and replayed ACP feeds ignore it as an execution update so the original terminal or diff completion is not overwritten.
-
-#### KV Cache effect
-
-Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries.
-
-### Permission preset switches
-
-#### What the model sees
-
-`session/set_config_option` emits no model message itself. When `dsh-permission` is composed, the bridge writes the selected preset through that service; the resulting model-visible policy prompt and change notice belong to [`dsh-user-approval`](../user-approval/README.md), while sandbox-mode effects belong to [`dsh-tool-bash`](../../bash/tool-bash/README.md). The ACP `Permissions` select, its option descriptions, pending idle value, and refreshed config response remain client-only.
-
-#### Token effect
-
-Zero direct tokens from the ACP option or the log-only `permission/preset` event. Downstream cost is limited to the owning plugins' policy prompt, conditional retained change notice, and any changed tool outcome.
-
-#### KV Cache effect
-
-The ACP option and log event cause no direct invalidation. The downstream policy-prompt change may invalidate reuse from that system section, while its change notice appends to history.
-
-### Model switches
-
-#### What the model sees
-
-The ACP selector itself emits no message. The selected provider/model pair supplies the next step's `{{provider}}` / `{{model}}` prompt variables and request routing together; all other call-config fields continue through the `agent/request` waterfall unchanged.
-
-#### Token effect
-
-The selector adds no direct tokens. A changed model may tokenize the same retained prompt/history differently, and any persona text that interpolates provider or model changes accordingly.
-
-#### KV Cache effect
-
-Switching provider or model selects a different cache domain. If the persona interpolates either value, the rendered system prompt also changes and prevents reuse from its first changed token.
-
-### Loaded sessions
-
-#### What the model sees
-
-`session/load` resumes the persisted log, after which the loop sends its reconstructed history and request header. Replaying that log to the editor is not an extra model message.
-
-#### Token effect
-
-Restored context has the persistence and session packages' normal retained cost; ACP replay to the client adds none.
-
-#### KV Cache effect
-
-Loading does not rewrite the stored log, but the next request is reconstructed under the current envelope and route. Reuse requires that reconstruction to match; ACP replay to the client has no cache effect.
-
-## Known Limitations and Deferred Work
-
-- **`additionalDirectories`** — rejected. A session operates in its single `cwd` (see Per-session cwd); widening the tool/filesystem scope to extra roots is a separate sandbox concern, not yet implemented.
-- **Prompt content is `text` + `resource_link` only** — image, audio, and embedded-resource blocks are rejected, as is a non-empty `mcpServers` list at `session/new`.
-- **Session picker UI is client-owned** — `session/list` supplies standard title metadata and, when references are available, a canonical URI extension; an ACP client must consume those fields to add an `@` picker. Title/body search remains future metadata or FTS work.
-- **Terminal cards render completed output** — live incremental streaming and command classification are named follow-ups of [the terminal-rendering Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-acp-terminal-and-tool-rendering.md).
-- **Permission answers are one-shot only** — the bridge offers `allow_once` / `reject_once`; durable `allow_always` grants and their storage/revocation policy remain deferred to the approval seam.
-- **Command output is live-only** — discovery is refreshed after load, but direct command results are not persisted or replayed into a reconnected editor.

-# ACP feature support checklist
-
-A structured inventory of [Agent Client Protocol](https://agentclientprotocol.com) (ACP) features and where the harness's ACP bridge ([`@deepseek-ai/dsh-acp`](README.md)) stands on each. The bridge exposes the harness agent as an ACP **server** (the agent side of an editor↔agent connection), so "supported" below means *the bridge implements the agent's half* — answering an agent method, advertising a capability, or calling a client method.
-
-## Scope
-
-This tracks the **stable** ACP v1 surface (schema `1.14.0`, `schema/v1/schema.json`) PLUS the **unstable/draft** features that the two reference adapters — [`claude-agent-acp`](https://github.com/zed-industries/claude-code-acp) (Claude Code) and [`codex-acp`](https://github.com/zed-industries/codex-acp) (OpenAI Codex) — actually ship. A purely-unstable feature that neither reference adapter uses is omitted (see [Out of scope](#out-of-scope)).
-
-Legend: ✅ supported · ⚠️ partial / fallback · ❌ not yet · — n/a. The **Stable** column marks whether the feature is in the released v1 schema (S) or only the unstable schema (U). The **Claude** / **Codex** columns record whether each reference adapter ships it, as a maturity signal.
-
-## At a glance
-
-The bridge implements the **core prompt-turn loop** for N concurrent sessions: initialize, session new/load/list, prompt, cancel, streamed assistant/thought chunks, tool-call rendering (including Zed terminal cards), resumable session replay, slash commands, one-shot permission prompts, per-session model selection and permission presets, and **session modes** (the picker, via `@deepseek-ai/dsh-plan-mode`). The largest **unbuilt** areas are **MCP passthrough** and **agent plans**, plus the client **filesystem** and **terminal** method families (which the adapters mostly do NOT drive either — see rows 43-49). See [Gap summary](#gap-summary).
-
-## 1. Agent methods (client → agent)
-
-| Method | Stable | Bridge | Claude | Codex | Notes |
-|---|---|---|---|---|---|
-| `initialize` | S | ✅ | ✅ | ✅ | Negotiates `PROTOCOL_VERSION`; advertises `loadSession`, `sessionCapabilities.list`, and baseline prompt caps. Snapshots the Zed `_meta.terminal_output` client cap. |
-| `authenticate` | S | ⚠️ | ✅ | ✅ | No-op stub; the bridge advertises no `authMethods`, so there is nothing to authenticate. |
-| `logout` | S | ❌ | ✅ | ✅ | Gated by `agentCapabilities.auth.logout`; not advertised. |
-| `session/new` | S | ✅ | ✅ | ✅ | Maps to `agents.create`; requires an absolute `cwd` (becomes the session workspace); rejects non-empty `additionalDirectories` / `mcpServers`. |
-| `session/load` | S | ✅ | ✅ | ✅ | Maps to `agents.resume` + full event-log replay; validates persisted `cwd` before constructing the agent. |
-| `session/resume` | S | ❌ | ✅ | ✅ | Reconnect WITHOUT replay; gated by `sessionCapabilities.resume`. Not advertised. |
-| `session/close` | S | ❌ | ✅ | ✅ | No `session/close` handler — the SDK dispatch returns `method_not_found`. The bridge tears sessions down on client disconnect / Cordis disposal (cross-cutting, see [§8](#8-cross-cutting)), but that is not the on-demand per-session method. |
-| `session/prompt` | S | ✅ | ✅ | ✅ | A flattened prompt beginning with `/` dispatches through `ctx.commands` without a model request; ordinary input maps to `agent.send`. One request is in flight per session. |
-| `session/cancel` | S | ✅ | ✅ | ✅ | Aborts the exact direct command, or applies queue-aware `agent.cancel` and settles its prompt `cancelled`, scoped to one session. |
-| `session/set_mode` | S | ✅ | ✅ | ✅ | Composed opportunistically: with `@deepseek-ai/dsh-plan-mode` mounted, `session/new`/`session/load` advertise the fixed `default` / `plan` projection and `session/set_mode` records the boolean pending intent (optimistic `current_mode_update`; logged `plan/mode` lands at the turn boundary). Without the plugin: no `modes` advertised, `set_mode` rejected (see [§6 Modes](#6-session-modes--config-options--models)). |
-| `session/set_config_option` | S | ✅ | ✅ | ✅ | A provider/model select is present for a complete registered target; one `permission` select is added when `ctx.permission` is composed. Every response carries the complete refreshed state. |
-| model selection | S | ✅ | ✅ | ✅ | No distinct stable `session/set_model` — model is the `model`-category `session/set_config_option`. Values preserve the provider/model pair, catalogs come from `ctx.llm`, selection is per session, and `session/load` restores the last requested pair. Codex also supports the legacy `unstable_setSessionModel` ext method. |
-| `session/list` | S | ✅ | ✅ | ✅ | Uses live-preferred `ctx.sessionQuery`; returns absolute-cwd sessions newest-first with optional folded title and exact cwd filtering. Pagination is not emitted; supplied cursors are rejected. |
-| `session/delete` | S | ❌ | ✅ | ✅ | Gated by `sessionCapabilities.delete`. |
-| `session/fork` | U | ❌ | ✅ | ❌ | Claude ships `unstable_forkSession`; Codex does not. |
-
-## 2. Client methods the agent CALLS (agent → client)
-
-These are capabilities the bridge would *drive* on the editor. The harness runs tools in-process (its own `dsh-bash` executor, direct file I/O), so it does not yet delegate to the editor for any of these.
-
-| Method | Stable | Bridge | Claude | Codex | Notes |
-|---|---|---|---|---|---|
-| `session/update` | S | ✅ | ✅ | ✅ | The bridge's primary output channel (see [§4](#4-sessionupdate-variants)). |
-| `session/request_permission` | S | ✅ | ✅ | ✅ | The bridge answers the [`ctx.approval`](../user-approval/README.md) seam for the agents it owns: an `ask` from a hook/plugin becomes an editor prompt attached to the streamed tool call, one-shot `allow_once`/`reject_once` options only. Whether a call asks is policy (nothing asks by default); `allow_always` is deferred (grant storage). |
-| `fs/read_text_file` | S | ❌ | ✅ | ❌ | The harness reads files directly (it does not see the editor's unsaved buffer state). Claude delegates; Codex does not. |
-| `fs/write_text_file` | S | ❌ | ✅ | ❌ | Same — direct writes, no editor delegation. |
-| `terminal/create` | S | ❌ | ❌ | ❌ | Neither reference adapter drives the client terminal API either — both, like the bridge, render shell output as tool-call content + a `_meta` channel (see [§5 Terminal](#terminal-rendering)). |
-| `terminal/output` | S | ❌ | ❌ | ❌ | As above. |
-| `terminal/wait_for_exit` | S | ❌ | ❌ | ❌ | As above. |
-| `terminal/kill` | S | ❌ | ❌ | ❌ | As above. |
-| `terminal/release` | S | ❌ | ❌ | ❌ | As above. |
-| `elicitation/create` · `elicitation/complete` | U | ⚠️ | ✅ | ⚠️ | The bridge drives `unstable_createElicitation` for `ask_user_question` form prompts (session-scoped, no URL-mode flow yet). Claude calls the `unstable_*` elicitation methods for MCP server elicitations; Codex maps elicitations onto `session/request_permission`. |
-
-## 3. Capabilities
-
-### 3a. `agentCapabilities` (advertised by the bridge)
-
-| Capability | Stable | Bridge | Claude | Codex | Notes |
-|---|---|---|---|---|---|
-| `loadSession` | S | ✅ | ✅ | ✅ | Advertised `true`; backs `session/load`. |
-| `promptCapabilities.image` | S | ❌ | ✅ | ✅ | Bridge advertises `image: false`; image prompt blocks are rejected. |
-| `promptCapabilities.audio` | S | ❌ | ❌ | ❌ | `audio: false`; neither adapter accepts audio either. |
-| `promptCapabilities.embeddedContext` | S | ❌ | ✅ | ✅ | `embeddedContext: false`; embedded `resource` blocks rejected. |
-| `mcpCapabilities.{http,sse}` | S | ❌ | ✅ | ⚠️ | No MCP passthrough; `mcpServers` is rejected. Claude advertises http+sse, Codex http only. |
-| `sessionCapabilities.*` | S | ⚠️ | ✅ | ✅ | `list` is advertised; delete/resume/close/additionalDirectories/fork remain off. |
-| `auth.logout` | S | ❌ | ✅ | ✅ | Not advertised. |
-| `authMethods[]` | S | ⚠️ | ✅ | ✅ | Advertised as empty (no auth required to reach the model). |
-| `agentInfo` (name/version) | S | ✅ | ✅ | ✅ | Fixed literals: `deepseek-harness-acp` / `0.0.1` (not config). |
-| `_meta` custom caps | S | ❌ | ✅ | — | E.g. Claude's `claudeCode.promptQueueing`. The bridge advertises no custom `_meta`. |
-
-### 3b. `clientCapabilities` (consumed by the bridge)
-
-| Capability | Stable | Bridge | Notes |
-|---|---|---|---|
-| `fs.{readTextFile,writeTextFile}` | S | ❌ | Not consulted (the bridge never calls `fs/*`). |
-| `terminal` | S | ❌ | Not consulted; the bridge keys terminal rendering off the Zed `_meta.terminal_output` cap instead. |
-| `_meta.terminal_output` (Zed) | S (`_meta`) | ✅ | Snapshotted per session at create/load; gates terminal-card rendering. |
-
-## 4. `session/update` variants
-
-| `sessionUpdate` | Stable | Bridge | Claude | Codex | Notes |
-|---|---|---|---|---|---|
-| `agent_message_chunk` | S | ✅ | ✅ | ✅ | From `assistant/chunk` text-delta. |
-| `agent_thought_chunk` | S | ✅ | ✅ | ✅ | From `assistant/chunk` reasoning-delta. |
-| `user_message_chunk` | S | ✅ | ✅ | ✅ | Emitted during `session/load` replay to reconstruct the user side. |
-| `tool_call` | S | ✅ | ✅ | ✅ | Tool-owned presentation (`presentCall`); see [§5](#5-tool-call-rendering). |
-| `tool_call_update` | S | ✅ | ✅ | ✅ | From appended `tool/result` via `presentResult`; replacement results rewrite model context and do not duplicate or overwrite execution presentation. |
-| `plan` | S | ❌ | ✅ | ✅ | No agent plan emitted. Both adapters emit real plan entries (Codex's `CodexEventHandler.updatePlan` maps `turn/plan/updated` → `{ sessionUpdate: 'plan', entries }`). |
-| `available_commands_update` | S | ✅ | ✅ | ✅ | Full effective snapshot after create/load and registry changes; names, descriptions, and unstructured-input hints come from `ctx.commands`. |
-| `current_mode_update` | S | ✅ | ✅ | ✅ | Echoed optimistically on `session/set_mode` and re-notified when a logged `plan/mode` maps to a different wire id (covers the `exit_plan_mode` tool flipping the session back). |
-| `config_option_update` | S | ❌ | ✅ | ✅ | Config options exist (advertised in `session/new`/`session/load`, switched via `session/set_config_option`), but the bridge never pushes agent-initiated changes — an operator default drift is narrated to the MODEL, not echoed to the editor. Future work in the [sandbox Agent Note § Per-session mode switching](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md). |
-| `usage_update` | S | ❌ | ✅ | ✅ | Token/cost reporting not surfaced (the harness records token usage internally on `assistant/message`). |
-| `session_info_update` | S | ✅ | ⚠️ | ⚠️ | Log-backed title events push title and event time; load replay uses the same mapping. |
-
-## 5. Tool-call rendering
-
-Tool-call presentation is **owned by each tool** (`presentCall` / `presentResult` on the `dsh-tools` definition), not special-cased in the bridge — see the [terminal-and-tool-rendering Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-acp-terminal-and-tool-rendering.md).
-
-| Feature | Stable | Bridge | Claude | Codex | Notes |
-|---|---|---|---|---|---|
-| `ToolCallKind` mapping | S | ✅ | ✅ | ✅ | `execute`/`read`/`edit` declared by each tool's `presentCall`; presenter-less tools render `other` (no name sniffing); richer mapping possible. |
-| `ToolCallStatus` | S | ✅ | ✅ | ✅ | `in_progress` → `completed`/`failed`. |
-| `content` blocks | S | ✅ | ✅ | ✅ | Text content; the description renders above the card. |
-| `diff` content | S | ✅ | ✅ | ✅ | The `write`/`edit` tools declare a `diff` render intent: `presentCall` → a call-time `{ card: 'diff' }` snippet, and `presentResult` → a result-time `{ card: 'diff' }`. For an edit or an overwrite it carries the applied hunk(s) with surrounding context (one per `replace_all` site), computed from the before/after text and persisted on the `tool/result` event as `meta`; for a create (no before-image) it is an args-derived whole-file diff. The bridge emits `{ type: 'diff', path, oldText, newText }` content blocks; a successful mutation ALWAYS returns the result diff (an ACP `tool_call_update.content` replaces the call's content, so the result diff — not the model-facing text — is what survives). |
-| `terminal` content | S | ✅ | ✅ | ✅ | Via the Zed `_meta` terminal convention (see below), not the spec `terminal/*` sub-protocol. |
-| `locations` (follow-along) | S | ✅ | ✅ | ✅ | The `read`/`write`/`edit` tools emit `{ path, line? }` file-location hints via `presentCall`. |
-| `rawInput` | S | ✅ | ⚠️ | ✅ | Parsed tool args surfaced as `rawInput`. |
-| `rawOutput` | S | ❌ | ⚠️ | ✅ | Not emitted. |
-
-### Terminal rendering
-
-⚠️ Implemented via the **Zed `_meta` convention** (`terminal_info` / `terminal_output` / `terminal_exit`), gated on the client advertising `_meta.terminal_output` — NOT the spec's `terminal/create` sub-protocol (which would make the editor execute the command, bypassing `dsh-bash`'s sandbox / env-scrub / ownership / cwd). Both reference adapters take the same `_meta` approach. Live incremental streaming (`terminal_output_delta`, which Codex negotiates) is a follow-up — the bridge currently sends the full captured output once on the result.
-
-## 6. Session modes / config options / models
-
-Session modes ✅ (the [plan-mode Agent Note](../../../.agents/notes/implemented/feature/2026-07-07-plan-mode.md)): ACP owns the fixed `default` / `plan` wire vocabulary and projects it onto `ctx.planMode`'s boolean `{ active, pending? }` state; `session/set_mode` calls `set()` and `current_mode_update` tracks the optimistic selection plus each distinct committed `plan/mode` flip. Config options ✅: the bridge advertises a `model` select from the advisory LLM provider/model catalog, preserving each provider/model pair in an opaque value and grouping multiple providers. A selected pair is isolated to one session, snapshotted with the prompt for each step, applied through `agent/request`, and restored from the logged request header on load. When `ctx.permission` is composed, the bridge also advertises one `permission` select whose values come from the deployment preset table and whose current value derives from the session log; idle permission switches anchor at the next `agent/prompt-submit` inside its open turn. The division is picker-to-collaboration-state / knobs-to-config-options: individual environment knobs and the provider/model selector are not modes. See the [model-catalog Agent Note](../../../.agents/notes/implemented/architecture/2026-07-15-llm-model-catalog-and-acp-selection.md) and [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md).
-
-## 7. Content blocks
-
-| Block | Stable | In prompts | In updates | Notes |
-|---|---|---|---|---|
-| `text` | S | ✅ | ✅ | Baseline. |
-| `resource_link` | S | ✅ | ⚠️ | Accepted in prompts and rendered into text (`acpPromptToText`); not emitted as a structured update block. |
-| `image` | S | ❌ | ❌ | Rejected in prompts (`promptCapabilities.image: false`). |
-| `audio` | S | ❌ | ❌ | Rejected. |
-| `resource` (embedded) | S | ❌ | ❌ | Rejected (`embeddedContext: false`). |
-
-The bridge rejects unsupported prompt blocks rather than silently dropping them (`promptHasUnsupportedContent`), per the "explicit over implicit" convention.
-
-## 8. Cross-cutting
-
-| Feature | Stable | Bridge | Notes |
-|---|---|---|---|
-| `StopReason` mapping | S | ✅ | `turnEndToStopReason` is total over harness turn-end reasons → `end_turn`/`max_tokens`/`cancelled`. |
-| Multi-session (N per connection) | S | ✅ | Strict per-session demux; concurrent streams never interleave. See the [multi-session Agent Note](../../../.agents/notes/implemented/feature/2026-06-14-acp-multi-session.md). |
-| Disconnect / disposal teardown | S | ✅ | Quiesces every live session on client disconnect or Cordis disposal. |
-| `_meta` extensibility | S | ⚠️ | Consumed for the Zed terminal cap and emitted for terminal cards. Listed sessions add `deepseek-harness/sessionReference` with a canonical URI when cross-session references are mounted. |
-| Background-task ownership isolation | — | ✅ | Generic `task_output`/`task_kill` reject tasks whose branded owner `SessionId` belongs to another session. |
-| stdout-is-the-protocol guarantee | S | ✅ | The bridge runs in an example with no stdout logger. |
-
-## Gap summary
-
-Ranked by how commonly the reference adapters ship them and how much UX they unlock:
-
-1. **Session lifecycle** — `session/delete`, then `session/resume` / `session/close`.
-2. **Agent plan** (`sessionUpdate: 'plan'`) — surface the loop's plan as structured entries.
-3. **MCP passthrough** (`mcpServers` on `session/new` + `mcpCapabilities`).
-4. **Richer prompt content** — image / embedded `resource` blocks (needs a multimodal model path).
-5. **Usage reporting** (`usage_update`) — the harness already records token usage internally (on `assistant/message`).
-6. **Editor filesystem delegation** (`fs/read_text_file` / `fs/write_text_file`) — lets the agent see unsaved buffers; lower priority since the harness has direct disk access.
-
-## Out of scope
-
-Unstable/draft ACP features that **neither** reference adapter ships are not tracked above: `providers/*` (LLM provider selection), `mcp/connect`·`mcp/message`·`mcp/disconnect` (client-side MCP passthrough), `nes/*` (Next Edit Suggestion), `document/did*` (LSP-style document sync), the v2 plan model (`plan_update` / `plan_removed`), boolean config options, `$/cancel_request`, and the draft Streamable-HTTP transport. They can be added if a target editor adopts them.

-# ACP Snapshot Replay
-
-This graph explains what a snapshot scenario proves: recorded real-model session logs are replayed keylessly, ACP stdout is normalized and diffed, and scenario workspaces preserve tool side effects that the UI stream alone cannot prove.
-
-```mermaid
-sequenceDiagram
- participant Recorder as Real API recording
- participant Fixture as snapshot fixture
- participant Workspace
- participant Replay as llm-replay adapter
- participant ACP as acp-agent subprocess
- participant Expected as stdout expected output
- Recorder->>Fixture: session.jsonl + workspace inputs
- Fixture->>Workspace: seed files and hook configs
- Fixture->>Replay: recorded StreamChunk script
- Replay->>ACP: deterministic <code>llm/stream</code> chunks
- ACP->>Workspace: bash, fs, and hook side effects
- ACP->>Expected: normalized sessionUpdate stream
- Expected-->>ACP: diff must be empty
-```
-
-The fs and hook snapshot matrix is valuable because it proves world state, hook decisions, and failed tool-card rendering, not just that replay returns text.

-Maintenance mode: curated Mermaid sequence based on the snapshot test harness.

+Shared boot glue for the app bins ([`dsh`](../../../apps/cli/README.md), [`dsh-cli-demo`](../../examples/cli-demo/README.md), [`dsh-acp-demo`](../../examples/acp-demo/README.md)): each bin is a thin self-executing composition over these helpers, parameterized by its diagnostic prefix, so the loader-failure lore lives once — under the per-file coverage gate — instead of drifting between published artifacts.
| Export | Role |
|---|---|
| `resolveConfigPath(path, snapshotMode, cwd?)` | Absolute config path; `snapshotMode === 'replay'` swaps a `cordis.yml`/`.yaml` basename for its sibling `cordis.snapshot.yml` |
-| `parseResumeArg(argv)` | Split the `--resume <id>` / `--resume=<id>` flag out of the arguments, returning `{ resumeSessionId, rest }`; a valueless, empty, or repeated flag throws so a mistyped resume fails loud instead of silently starting fresh |
| `loadEnv(binName, dir?, warn?)` | Load the gitignored `.env` (Node `process.loadEnvFile`); absent file is fine, an unloadable one warns a single labelled line (default: stderr) |
| `installFailLoud(binName, proc?)` | Turn a post-`boot()` unhandled Loader rejection into one labelled stderr line + `exit(1)`; returns the uninstaller (for tests) |
| `assertEntriesLoaded(ctx, binName)` | Throw when a settled tree holds an enabled entry with no fiber (a plugin module that failed to import) |
| `loadPersonalPatches(binName, dir?)` | Parse the optional `config.yaml` in the Harness home (default [`resolveDshHome()`](../../util/paths/README.md): `$DSH_HOME`, else `~/.dsh`) — a top-level YAML array of include `PatchOptions` (id-targeted config overrides, `insert` lists, `!!js` allowed); absent file → `undefined`, an unreadable/unparsable/non-array file throws |
-| `boot(binName, absoluteConfigPath, patches?)` | Mount the Loader, mount the statically imported include plugin as the `cordis:include` builtin (so the config may live outside `node_modules` reach), include the config by absolute `file://` URL with the optional overlay patches, await the whole tree, assert entries loaded, return the root context |
+| `boot(binName, absoluteConfigPath, patches?, prepare?)` | Create the root context, run optional host preparation before plugins mount (e.g. `ctx.provide(RESUME_SESSION_ID_KEY, id)`), then mount the Loader/include tree, await it, assert entries loaded, and return the root context |
+| `RESUME_SESSION_ID_KEY` | Context key a bin sets through `boot`'s `prepare` hook to hand a resume session id to the booted config; the config reads it as the bare identifier `resumeSessionId` in a `!!js` expression, so resuming needs no environment variable |
| `addHarnessSourceSection(ctx, sourceRoot)` | Add a global `harness:source` prompt section (ordered just after the harness identity, before the persona) telling the agent the on-disk path to its own source checkout; a no-op returning `undefined` when the booted tree has no `systemPrompt` service. The section is registered against that service's fiber, so a dev HMR reload of the system prompt drops it until the next boot |

-`ctx.commands.register(definition)` registers one lowercase command name, description, optional ACP-compatible unstructured-input hint, and abortable handler. A registered command is available to every composed command adapter; a plugin that is incompatible with a deployment does not register there. A plain-context registration is global. A command-producing plugin mounted beneath `agent.ctx` declares its own `commands` injection and creates an exact agent-scoped definition; it shadows a global definition with the same name. This child-injection shape preserves the agent scope without making the core agent loop depend on a UI service. Duplicate names within one layer fail during registration. Every disposer is the exact Cordis effect disposer, and registration or removal notifies every `commands/change` observer so live adapters can refresh discovery; observer failures are logged and cannot veto the registry mutation or starve later observers.

Each configured name bundles `sandbox/mode` with `approval/policy`; the defaults are `workspace-write` (`workspace-write` + `ask`) and `danger-full-access` (`danger-full-access` + `never`).

+User-facing permission presets through `ctx.permission` ([`PermissionService`](src/index.ts)). Each configured name bundles `sandbox/mode` with `approval/policy`; the defaults are `workspace-write` (`workspace-write` + `ask`) and `danger-full-access` (`danger-full-access` + `never`). UI adapters may expose the table as one selector, while sandbox execution and approval continue to consume their own knobs.
`set(session, name)` records a changed selection in a log-only `permission/preset` event, then calls each knob's setter only when its effective value changes. The selection event precedes the knob events and preserves user intent when presets share a bundle; a net-zero selection appends nothing. `current(events)` prefers a still-matching recorded selection, then the first matching table entry, and otherwise returns `custom`. Clients may display `custom` as the current value, but cannot select it.
-The service requires a confining `ctx.bash` executor and `ctx.approval`. A table entry named `custom` throws at load; composition defaults outside the table instead make a zero-event session derive `custom`.

A table entry named `custom` throws at load; composition defaults outside the table instead make a zero-event session derive `custom`. See the [sandbox switching design](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md).

+- **No shipped composition currently mounts the service** — the ACP bridge was its only selector before [ACP became automation-only](../../../.agents/notes/implemented/simplification/2026-07-23-acp-automation-only-protocol.md); the preset table is kept for the interactive front door that next exposes a runtime policy switch.
- **Only two mechanism knobs are bundled** — presets select sandbox mode and approval policy; an agent/profile choice is not part of `PresetSpec` yet.
- **`custom` is derived-only** — callers can switch away from an unmatched knob combination but cannot target or persist a named custom preset through this service.
- **The preset table is process-level** — configuration is fixed for the plugin lifetime; changing available presets requires reloading the plugin.

Typing `@` at a token boundary searches files and directories under the session working directory. A bare fuzzy query uses a reusable bounded workspace index; a query containing `/` lists that directory directly, and selecting a folder keeps completion open for descent. Whitespace-bearing paths are inserted as `@"path with spaces"`. Selecting a file inserts only its path and a trailing space: the TUI does not read it, attach hidden context, or replace it with a reference object. When a model-facing `read` tool is registered, the TUI adds one fixed system-prompt instruction telling the model to read an explicit path when its contents are needed.
-When optional `ctx.sessionReferences` is mounted, the same `@` menu also offers metadata-only session candidates, inserts `@[label](dsh-session:<payload>)`, and prepares the selected snapshots before dispatch. Session references remain structured because the model has no filesystem-like tool for retrieving session snapshots later. Preparation disables duplicate submission and restores the editor input on failure. The TUI chooses `agent.steer()` or `agent.send()` from the status after that asynchronous preparation, so idle sends still dispatch `agent/prompt-submit` while in-turn steering joins at a checkpoint without that hook.

-While the agent is running, ordinary editor submissions call `agent.steer()`; otherwise they call `agent.send()`. A slash at the start of the submitted line enters `ctx.commands` instead: known commands execute directly, unknown commands produce a warning, and neither path automatically reaches the model. A command producer may explicitly schedule agent work; [`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) uses that contract for `/plan [message]`. The TUI registers `/help`, `/model`, `/clear`, `/reasoning`, `/tools`, `/redraw`, `/reload`, `/resume`, `/status`, and `/exit` as agent-scoped definitions; every other effective command joins autocomplete and `/help` dynamically, as do `/skill:` completions. A status line above the editor reports the turn phase the TUI derives from session events — waiting for the first token, thinking, responding, or executing tools — with the elapsed time in that phase and the running step total, refreshed each second, and ends with the `Enter sends steering, Esc cancels` hint; while steering messages wait to reach the model it inserts a `N queued ·` badge before the hint that clears as each drains. Ctrl+C or Escape cancels a running turn. Tool cards collapse long bodies into a configurable head/tail preview; Ctrl+O toggles every card between its preview and full output. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle.

`/model` opens the advisory `ctx.llm` catalog as a keyboard selector: Up/Down moves, Enter selects, and Escape closes it. `/model <model>` still selects an unambiguous model id directly, while `/model <provider>/<model>` selects an exact target. The configured target or latest logged request header initializes the selector, and an unlisted current model remains visible because catalogs are advisory. Selection is local to this TUI session. Prompt assembly snapshots the target for one step, replaces `{{provider}}` and `{{model}}`, and applies the same pair through `agent/request`; a switch during assembly therefore starts with a later step. The request header durably records targets that reach the model, while an unused selection remains process-local.

`/status` adds a point-in-time diagnostics card to the transcript and remains available while the agent runs. It reports the session id, title, working directory, selected provider/model, reasoning-block visibility, agent state, event/turn/step/tool-call counts, exact input/output/cache token buckets, KV-cache hit rate, token-meter context use and capacity, creation time, and latest event time. Missing titles, models, cache input, or context capacity are labeled instead of inferred. The card is terminal-only and does not duplicate the compact footer.
-When `resumeCommand` is set and a `sessionPersistence` backend is mounted, exiting prints the resume command for the current session (once it has been persisted, so an abandoned session yields no hint), and `/resume` lists this workspace's persisted sessions newest-first, each with its resume command and a marker on the current one. `{session}` in the template expands to the session id; the TUI only prints commands to copy and never resumes in place.
+`/resume` opens a full-viewport keyboard selector over the current workspace instead of a centered dialog. Its focused search field starts immediately after the search glyph and emits pi-tui's cursor marker, so terminal IME composition remains anchored inside the field. Candidates are sorted by last logged activity and searchable by log-backed title or session id; each row reports current/live/persisted state, last turn outcome, recent provider/model, and durable goal phase when present. Up/Down and Page Up/Page Down navigate, Enter resumes, Escape clears a non-empty search before a second Escape cancels, and Ctrl+C cancels directly. The current session, a session already live in this runtime, an unreadable log, a mismatched cwd, or a session whose logged provider has no current adapter remains visible but disabled. Selection repeats those checks and requires the current agent to be idle before flushing the current session. The TUI then stops the terminal UI and calls the optional host-owned `TuiRuntime.handoffResume`; where `process.execve` is available, the shipped `dsh` host disposes the app and replaces its process. Resume restores the same `SessionId`, transcript, title, todos, and durable goal; goal activation remains disarmed and the TUI asks for human confirmation or `/goal resume`.
+
+`resumeCommand` remains the deployment-owned fallback: exiting prints it only after the current session is durable, and a host without in-place handoff shows the selected session's command. `{session}` expands to the session id. TUI code never executes the template or arbitrary shell text.

## Known Limitations and Deferred Work
+- **Resume has no cross-process session lock** — the selector rejects sessions known to be live in its own runtime, but another process can resume the same persisted id before or during handoff. Deployments that can run concurrent hosts must coordinate ownership outside the TUI.
- **One configured session owns the transcript and editor** — questions from other agents can still use the shared overlay provider, but session rendering and prompt input remain bound to `sessionId`.
- **Tool cards are text terminal presentations** — terminal, diff, and generic cards use tool-owned titles/content, but session content currently has no image block for inline image rendering.
- **Non-TTY operation is intentionally unsupported** — app bundles that need automation must compose a one-shot or server front door (`dsh-cli-demo`, `dsh-acp`) rather than expecting an internal fallback.

+
+Ownership truth lives in the workspace record's `sessionIds` (ordered), never derived from session cwd; `attachSession` verifies the session header's cwd resolves to the workspace path, so one session structurally belongs to at most one workspace. Deletion (workspace and session cascade) is deliberately absent this phase and ships with the session-side primitives.

+# @deepseek-ai/dsh-workspace
+
+Workspace entity registry (`ctx.workspace`) for the DeepSeek Harness: durable workspace records, stable workspace order, and a newest-first candidate session index stored through the domain data form. Consumers see the `Workspace` interface; the entity implementation stays package-private.
+
+The entity/storage rationale lives in the [domain Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md); header-only bootstrap and GUI ordering live in the [Workspace UI product-flow Agent Note](../../../.agents/notes/implemented/feature/2026-07-25-workspace-ui-product-flow.md).
+
+## Shape
+
+- `ctx.workspace.create(path, title?)` — canonicalizes `path` via `fs.realpath`, rejects a nonexistent or non-directory path, creates at most one record per canonical path, and prepends a new record to durable workspace order. Repeated calls for that path return the existing workspace without changing its title; a different path cannot create a duplicate title.
+- `ctx.workspace.get(id)` / `list()` / `resolveByPath(path)` — cache-served lookups. `list()` is synchronous and follows durable registry order; `resolveByPath` is async because it applies the same `realpath` canon and rejects a missing path rather than creating it.
+- `Workspace.attachSession(id)` — validates a live or persisted session header cwd against the workspace path and prepends a new id. Unknown sessions, absent/unresolvable/non-directory cwd values, and mismatches reject without writing. `detachSession` removes only the candidate index entry.
+- `ctx.workspace.touchSession(id)` — moves only that validated, accounted session to the front. Ungrouped or filtered sessions are no-ops, and workspace order never changes.
+- `Workspace.sessionIds` — synchronous id-plus-canonical-cwd membership projection in durable candidate order. Missing headers, invalid cwd values, and mismatches are filtered; the next workspace mutation prunes them. A medium indexing one session under two workspaces, claiming one path from two records, or diverging from durable workspace order rejects at startup.
+- `Workspace.status()` — uncached directory check, `'ok' | 'missing-dir'`; a missing directory never mutates the record.
+
+`storageDomain` and `sessionPersistence` are required startup dependencies. An unavailable peer leaves the plugin pending and cannot commit an empty initialized marker. On the first successful start, the registry calls `SessionPersistence.list()` and uses only header `id`, `cwd`, and `createdAt` to group valid historical directories and persist initial order; it never reads event bodies. The initialized marker is written last, so partial bootstrap writes are reused safely after restart. Later cwd-only sessions remain Ungrouped.
+
+## Model Experience
+
+### Workspace records and session accounts
+
+#### What the model sees
+
+Nothing. `ctx.workspace` serves workspace records to host-side consumers only: the package registers no tools, injects no prompts, and writes no session events, so no request field ever carries this package's data.
+
+#### Token effect
+
+Zero direct tokens on every request.
+
+#### KV Cache effect
+
+Independent of live requests: the package never touches a request prefix, so it cannot invalidate provider cache reuse.
+
+## Known Limitations and Deferred Work
+
+- No delete entry point in this phase — workspace deletion ships as one complete semantic together with the session-delete primitive and cascade orchestration (future-work section of the Agent Note); a half "drop the record, keep the sessions" operation is deliberately not exposed.
+- The header index refreshes at startup and when attach must resolve an uncached persisted id; deletion or cwd damage performed by another process is observed after the next refresh or restart.

`provider` selects a provider route registered by the chosen Cordis composition; `model` is the model id resolved by that adapter. The bundled default composition registers `deepseek`. A custom composition can mount `llm-pi-ai`, configure provider-specific credentials/endpoints there, and select any provider/model present in pi-ai's installed catalog.
-`TurnResult.final_response` is the text content from the last
-`assistant/message` event in the turn. Use `TurnResult.events` for the complete
-event stream, including intermediate assistant messages and tool activity.
+`HarnessClient` retains discovered subagent ancestry for the lifetime of the runtime process. During each `Session.run()`, `TurnResult.notifications` and `on_notification` receive the root session and all known descendant notifications in wire order, including nested subagent lifecycle and session events. `TurnResult.events` remains the root session's complete event stream, and `TurnResult.final_response` is the text content from its last `assistant/message`; descendant messages therefore cannot replace the root response.
The same behavior can be selected for the runtime subprocess with `DSH_CORDIS_CONFIG`. The injection lives in `HarnessClient.start()`, so the low-level client's default launch gets it too: when the launch resolves to the bundled runtime and neither `cordis` nor a non-empty `DSH_CORDIS_CONFIG` is set (the runtime treats an empty value as absent, and so does the injection check), the bundled default configuration is used; an explicit `runtime_bin`, `bridge_bin`, or `launch_args_override` disables the injection entirely. See the [sdk-runtime README](../sdk-runtime/README.md) for the runtime carriers (production exe vs dev-only node closure) and how to obtain them.

`provider` 用于选择当前 Cordis 组合已注册的提供方路由；`model` 是该适配器解析的模型 ID。内置默认组合注册 `deepseek`。自定义组合可以挂载 `llm-pi-ai`，在其中配置各提供方的凭据与端点，再选择 pi-ai 已安装目录中的任意提供方/模型组合。

+`HarnessClient` 会在运行时进程的生命周期内保留已发现的 subagent（子 agent）祖先关系。每次执行 `Session.run()` 时，`TurnResult.notifications` 与 `on_notification` 会按线上的原始顺序收到根会话及所有已知后代的通知，其中包括嵌套 subagent 的生命周期与会话事件。`TurnResult.events` 仍只保存根会话的完整事件流，`TurnResult.final_response` 则取该会话最后一个 `assistant/message` 的文本内容，因此后代消息不会覆盖根会话回复。
同样的行为也可以通过 `DSH_CORDIS_CONFIG` 为运行时子进程选定。注入逻辑位于 `HarnessClient.start()`，因此底层客户端的默认启动也具有此行为：当启动解析到内置运行时，且 `cordis` 与非空的 `DSH_CORDIS_CONFIG` 均未设置时（运行时把空值视为缺省，注入检查与之一致），使用内置的默认配置；显式给出 `runtime_bin`、`bridge_bin` 或 `launch_args_override` 则完全禁用注入。运行时载体（生产用 exe 与仅限开发的 `node` 闭包）及其获取方式见 [sdk-runtime README](../sdk-runtime/README.md)。

- "content": "# Translation Prompt\n\nYou are a senior technical translator specializing in LLM and agent development documentation. Your task is to translate the given source document from English to Chinese, producing natural, professional technical prose.\n\n## Quality Requirements\n\n### Structure and Format Preservation\n- Output a complete translated document that maintains exactly the same structure as the source: heading hierarchy, list shape, table columns, link targets, and code blocks.\n- Fenced code blocks must be byte-identical to the source, including ALL comments inside them. Do NOT translate comments inside code blocks. This is a hard rule with no exceptions.\n- Inline code spans (commands, flags, paths, API names, version numbers) must be kept verbatim. Never translate or reformat them.\n- Every relative link must point to the same target as in the source. Link text is translated; link targets are not.\n- Language switcher line: when translating into Chinese, write `[English](source-filename.md) | 中文`. When translating into English, write `English | [中文](source-filename.zh.md)`. Do NOT copy the switcher line from the source file unchanged — you must flip the link direction.\n- After a closing bold marker `**`, insert a space before the next character when that character is a Latin letter, digit, or CJK ideograph. Never insert a space before any punctuation (full-width or half-width).\n\n### Tone and Style\n- The translation must read as if originally written in the target language by a native speaker. If an expression sounds like a word-for-word rendering from the source language, rephrase it.\n- Write in a professional, formal tone appropriate for developer documentation. Never use colloquial or casual expressions.\n- Use polite imperative forms where the text instructs the reader to do something.\n- Keep the author's register: concise stays concise, detailed stays detailed.\n\n### Sentence Structure\n- Break long sentences with commas or semicolons. Avoid run-on sentences.\n- Prefer active voice. Convert passive constructions to active if it reads more naturally.\n- Translate meaning, not words. Restructure sentences where the target language grammar requires it.\n- Do not invent words or expressions that do not exist in natural technical writing of the target language.\n\n### Word Choice\n- Prefer precise, formal vocabulary over casual or colloquial alternatives.\n- When multiple synonyms exist, choose the one most commonly used in professional technical documentation of the target language.\n- Avoid slang, internal jargon, or overly literal translations that would not be recognized by the general developer audience.\n- Do not use the same word to translate two different source-language terms that carry distinct meanings.\n- Avoid repeating the same verb in close proximity; vary word choice for readability.\n\n#### When translating into Chinese\n- When a number modifies a noun, always include a Chinese classifier or measure word (量词). For example: \"three-package seam\" → \"由三个包构成的 seam\", not \"三包 seam\".\n\n### Punctuation\n\n#### When translating into Chinese\n- Use full-width Chinese punctuation in prose: `，。：；？！（）「」`.\n- Strongly prefer replacing all em-dashes (——) with colons, periods, commas, or parentheses. Keep an em-dash only if no other punctuation works at all.\n- Use enumeration commas (、) between parallel items, not regular commas.\n- List item endings: use semicolons or no punctuation. Do not end list items with commas.\n- Put one half-width space between Chinese text and Latin words/numbers.\n- For RFC 2119 keywords (MUST, MUST NOT, SHOULD, MAY), translate to the corresponding Chinese term (必须、禁止、应当、可以) and keep the SOURCE emphasis marker: plain source stays plain (必须), italic source stays italic (*必须*), and bold source stays bold (**必须**).\n\n#### When translating into English\n(To be added.)\n\n## Terminology\n\nA terminology table is provided below. Follow it strictly:\n- Render every listed term exactly as specified.\n- When the target language is Chinese, use the \"中文\" column. On first occurrence, write the \"首次出现\" value with its parenthetical gloss; on subsequent occurrences, write only the part before the parentheses.\n- When the target language is English, use the \"English\" column without a Chinese gloss; do not copy the \"中文\" or \"首次出现\" value into English prose.\n- If a term has already been glossed as part of a compound term, do not gloss it again when it appears alone later.\n- NEVER use translations listed in the \"不要译作\" column.\n- For technical terms not in the table, follow the target language: for a Chinese target, use an established Chinese rendering from a major Chinese-language OSS or vendor source, or keep the source term and flag it as pending when no such precedent exists; for an English target, use the established English technical term, or preserve an ambiguous source term with a short English gloss and flag it as pending. Do not invent a translation. This rule applies to terminology only; for general prose, freely restructure and paraphrase for natural expression.\n\n# Terminology\n\n本表约定本仓库的中英术语统一译法。\n\n**通用规则：**\n- \"中文\"列为中文译文的正文默认用词。若该列为英文，则中文译文的正文中保留英文不翻译。\n- 首次出现按\"首次出现\"列书写（带括号注释）；后续出现只写括号前的部分（可能为中文，也可能为英文），不出现括号内的注释。\n- \"不要译作\"列为严格禁止的译法。\n- 如果某术语已经作为另一个术语的组成部分被括注过（如 `agent loop（智能体循环）` 中已包含 `agent` 的括注），则该术语后续单独出现时无需再次括注。\n\n## 缩写类（中英文文本中均使用缩写）\n\n| English | 中文 | 首次出现 | 不要译作 | 备注 |\n|---|---|---|---|---|\n| ACP | ACP | ACP（Agent Client Protocol） | | |\n| AI | AI | AI（人工智能） | | |\n| API | API | | | |\n| CI | CI | | | |\n| CLI | CLI | CLI（命令行界面） | | |\n| e2e | e2e | | | |\n| HMR | HMR | HMR（热模块替换） | | |\n| JSON Schema | JSON Schema | | | |\n| JSONL | JSONL | | | |\n| LLM | LLM | LLM（大语言模型） | | |\n| MCP | MCP | | | |\n| PR | PR | PR（Pull Request） | | |\n| RAG | RAG | RAG（检索增强生成） | | |\n| SDK | SDK | | | |\n| SSE | SSE | SSE（Server-Sent Events） | | |\n\n## 英文类（中英文文本中均使用英文）\n\n| English | 中文 | 首次出现 | 不要译作 | 备注 |\n|---|---|---|---|---|\n| agent | agent | agent（智能体） | | |\n| Agent Note | Agent Note | Agent Note（agent 决策记录） | 智能体注记、智能体笔记 | 本仓库中由 agent 撰写的提案与决策记录 |\n| agent harness | agent harness | agent harness（智能体框架） | | agent 组合词（agent harness/workflow/loop/skill 等）整体保留英文；未括注过 agent 时首现按对应组合词或 agent 行处理 |\n| agent loop | agent loop | agent loop（智能体循环） | | |\n| backlog | backlog | backlog（待翻清单） | | 仅在双语翻译语境里括注`待翻清单` |\n| blob hash | blob hash | | | `git hash-object` 的结果 |\n| Cordis | Cordis | | | |\n| dispose | dispose | dispose（资源释放） | | |\n| doc-sync | doc-sync | doc-sync（文档同步门禁） | | |\n| fiber | fiber | | | |\n| fixture | fixture | fixture（测试前置数据） | | |\n| fork | fork | | | |\n| Function Calling | Function Calling | Function Calling（函数调用） | | |\n| harness | harness | | | |\n| harness engineering | harness engineering | | | |\n| lint | lint | | | |\n| mock | mock | | | 保留英文；指测试替身 |\n| loader | loader | | | |\n| manifest | manifest | manifest（元数据清单） | | |\n| monorepo | monorepo | | | |\n| schema | schema | | | |\n| schema DSL | schema DSL | | | |\n| seam | seam | | | 与 `extension point` 是不同概念；根据具体语境，可译为`服务边界`或`可替换点` |\n| skill | skill | skill（技能） | | |\n| spawn | spawn | | | |\n| steering | steering | steering（中途引导） | | |\n| task id | task id | | 任务 id | 保留英文 |\n| subagent | subagent | | | |\n| thinking | thinking | | | API 字段保留英文；描述模型模式时译为`思考` |\n| transcript | transcript | transcript（文本记录） | | 指会话渲染给用户或编辑器的完整文本，区别于事件日志 |\n| waterfall | waterfall | waterfall（瀑布式事件） | | |\n| wheel | wheel 包 | | | Python 打包格式 |\n| worktree | worktree | | | git 工作区概念 |\n| Zstandard | Zstandard | | | RFC 8878 compression format;

If Markdown inside any section body contains a line consisting only of `<translation>`, `</translation>`, `<review>`, `</review>`, `<final>`, or `</final>`, prefix that line with `\\`. If the original line already has one or more backslashes immediately before the tag, add one more. The parser removes exactly one framing escape; tags mentioned inline need no escaping.\n\n```xml\n<translation>\n(Complete translation of the source document)\n</translation>\n\n<review>\n(Self-review notes, one correction per line with category tag, e.g.)\n- [Tone] \"旁挂记录\" → \"伴随记录\"（生造词）\n- [Sentence] 第 3 段补充逗号断句\n- [Punctuation] 两处破折号替换为冒号\n- 无修正\n</review>\n\n<final>\n(Final translation after corrections)\n</final>\n```\n\n## Self-Review Instructions\n\nAfter writing `<translation>`, re-read it in the target language only, without looking at the source. Check by category:\n\n**Structure**\n- Is the heading hierarchy, list shape, and code block content identical to the source?\n- Are ALL comments inside code blocks left untranslated (byte-identical to source)?\n- Is the language switcher line correctly flipped (not copied from source)?\n- Are link targets preserved, and are spaces after bold markers present only before Latin letters, digits, or CJK ideographs?\n- Are wrapper-tag lines inside section bodies escaped with one additional backslash?\n\n**Tone & Style**\n- Does every sentence read as if originally written by a native speaker?\n- Is there any colloquial, casual, or overly informal phrasing?\n\n**Sentence Structure**\n- Are there run-on sentences that need breaking?\n- Are there stiff passive constructions that should be converted to active voice?\n\n**Word Choice**\n- Are there overly literal translations that sound unnatural?\n- Is the same target-language word used to translate two distinct source concepts?\n- Is any slang or internal jargon present?\n\n**Terminology**\n- For a Chinese target, are first-occurrence glosses correctly applied (not missing, not repeated)? For an English target, are Chinese glosses absent?\n- Are any \"不要译作\" forbidden translations present?\n- For unlisted terms, does a Chinese target use established Chinese precedent or retain the source term as pending, and does an English target use established English terminology or preserve only an ambiguous source term with a short English gloss?\n\n**Punctuation** (when target is Chinese)\n- Are there em-dashes that should be replaced with colons, periods, or commas?\n- Are list items ending with commas instead of semicolons?\n- Do RFC 2119 keywords preserve the source emphasis exactly?\n\nRecord corrections in `<review>` with category tags. Then output the corrected version in `<final>`. If no corrections are needed, write \"无修正\" in `<review>` and copy the translation unchanged into `<final>`.\n\n## Examples\n\nBelow are representative examples of common problems and their corrections. Follow the \"Good\" versions.\n\n### Colloquial verb → Professional verb\n- Source: `The repo pins pnpm@11.7.0 in package.json`\n- Bad: `仓库在 package.json 中钉住 pnpm@11.7.0`\n- Good: `该仓库在 package.json 中固定使用 pnpm@11.7.0`\n\n### Run-on sentence → Natural phrasing with pause\n- Source: `Read docs/architecture.md before changing anything under packages/.`\n- Bad: `改动 packages/ 下的任何东西之前先读 docs/architecture.md。`\n- Good: `在修改 packages/ 目录下的任何内容之前，请先阅读 docs/architecture.md。`\n\n### Stiff passive voice → Active and natural\n- Source: `a green gate means the pair was confirmed consistent at these exact contents, not that the confirmation was sound.`\n- Bad: `门禁绿意味着这对文档曾在当前内容上被确认一致，不意味着这次确认本身是对的。`\n- Good: `门禁通过意味着这组文档在当前内容上的一致性得到了确认，不代表确认本身正确可靠。`\n\n### Invented word → Natural expression\n- Source: `A sidecar record of both blob hashes makes consistency checkable`\n- Bad: `旁挂记录两侧 blob hash，使一致性可检查`\n- Good: `伴随记录保存两侧 blob hash，使一致性可检查`\n\n### Em-dash → Colon/period\n- Source: `FIXME — an issue that should block a new release. A release should not ship with an open FIXME unless reviewers explicitly agree the change can be merged anyway.`\n- Bad: `FIXME——应当阻塞新版本发布的问题。除非评审者明确同意可以照常合入，发布不应带着未解决的 FIXME 出门。`\n- Good: `FIXME：应当阻塞新版本发布的问题。除非评审者明确同意该更改可以合并，否则发布版本不应包含未解决的 FIXME。`\n\n### Overly literal → Meaningful rendering\n- Source: `awkward phrasing is easier to hear without the source anchoring you`\n- Bad: `没有源文锚着，别扭的表述更容易被听出来`\n- Good: `不对照原文时，更容易察觉别扭的表达`\n\n### Terminology — do not translate what should be kept in English\n- Source: `typed service seams, and explicit extension points`\n- Bad: `类型化的服务 seam（扩展点）与显式扩展点`\n- Good: `类型化的服务 seam 与显式扩展点`\n\n### Slang/jargon → Professional phrasing\n- Source: `The committed agent workflow lives in .agents/skills/dsh-translate-docs`\n- Bad: `进仓的 agent 工作流见 .agents/skills/dsh-translate-docs`\n- Good: `仓库内置的 agent 工作流见 .agents/skills/dsh-translate-docs`\n\n### \"For humans\" — translate the intent, not the word\n- Source: `For humans, start with the development guide`\n- Bad: `对于人工读者，请先从开发指南开始`（\"人工读者\"生硬）\n- Good: `面向开发者：请先阅读开发指南`（\"开发者\"自然，且中文里冒号在此处更自然）\n\n### Code block comments — NEVER translate\n- Source code block contains: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)`\n- Bad: `# 全屏 TUI coding agent（需要 DEEPSEEK_API_KEY）`\n- Good: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)` (keep exactly as-is, byte-for-byte)\n\n### Language switcher — flip direction\n- Source file (English) has: `English | [中文](README.zh.md)`\n- Bad (copying source unchanged): `English | [中文](README.zh.md)`\n- Good (flipped for Chinese file): `[English](README.md) | 中文`\n\n---\n\nNow translate the following document:"

Restructure sentences where the target language grammar requires it.\n- Do not invent words or expressions that do not exist in natural technical writing of the target language.\n\n### Word Choice\n- Prefer precise, formal vocabulary over casual or colloquial alternatives.\n- When multiple synonyms exist, choose the one most commonly used in professional technical documentation of the target language.\n- Avoid slang, internal jargon, or overly literal translations that would not be recognized by the general developer audience.\n- Do not use the same word to translate two different source-language terms that carry distinct meanings.\n- Avoid repeating the same verb in close proximity; vary word choice for readability.\n\n#### When translating into Chinese\n- When a number modifies a noun, always include a Chinese classifier or measure word (量词). For example: \"three-package seam\" → \"由三个包构成的 seam\", not \"三包 seam\".\n\n### Punctuation\n\n#### When translating into Chinese\n- Use full-width Chinese punctuation in prose: `，。：；？！（）「」`.\n- Strongly prefer replacing all em-dashes (——) with colons, periods, commas, or parentheses. Keep an em-dash only if no other punctuation works at all.\n- Use enumeration commas (、) between parallel items, not regular commas.\n- List item endings: use semicolons or no punctuation. Do not end list items with commas.\n- Put one half-width space between Chinese text and Latin words/numbers.\n- For RFC 2119 keywords (MUST, MUST NOT, SHOULD, MAY), translate to the corresponding Chinese term (必须、禁止、应当、可以) and keep the SOURCE emphasis marker: plain source stays plain (必须), italic source stays italic (*必须*), and bold source stays bold (**必须**).\n\n#### When translating into English\n(To be added.)\n\n## Terminology\n\nA terminology table is provided below. Follow it strictly:\n- Render every listed term exactly as specified.\n- When the target language is Chinese, use the \"中文\" column. On first occurrence, write the \"首次出现\" value with its parenthetical gloss; on subsequent occurrences, write only the part before the parentheses.\n- When the target language is English, use the \"English\" column without a Chinese gloss; do not copy the \"中文\" or \"首次出现\" value into English prose.\n- If a term has already been glossed as part of a compound term, do not gloss it again when it appears alone later.\n- NEVER use translations listed in the \"不要译作\" column.\n- For technical terms not in the table, follow the target language: for a Chinese target, use an established Chinese rendering from a major Chinese-language OSS or vendor source, or keep the source term and flag it as pending when no such precedent exists; for an English target, use the established English technical term, or preserve an ambiguous source term with a short English gloss and flag it as pending. Do not invent a translation. This rule applies to terminology only; for general prose, freely restructure and paraphrase for natural expression.\n\n# Terminology\n\n本表约定本仓库的中英术语统一译法。\n\n**通用规则：**\n- \"中文\"列为中文译文的正文默认用词。若该列为英文，则中文译文的正文中保留英文不翻译。\n- 首次出现按\"首次出现\"列书写（带括号注释）；后续出现只写括号前的部分（可能为中文，也可能为英文），不出现括号内的注释。\n- \"不要译作\"列为严格禁止的译法。\n- 如果某术语已经作为另一个术语的组成部分被括注过（如 `agent loop（智能体循环）` 中已包含 `agent` 的括注），则该术语后续单独出现时无需再次括注。\n\n## 缩写类（中英文文本中均使用缩写）\n\n| English | 中文 | 首次出现 | 不要译作 | 备注 |\n|---|---|---|---|---|\n| ACP | ACP | ACP（Agent Client Protocol） | | |\n| AI | AI | AI（人工智能） | | |\n| API | API |

tags are framing. If Markdown inside any section body contains a line consisting only of `<translation>`, `</translation>`, `<review>`, `</review>`, `<final>`, or `</final>`, prefix that line with `\\`. If the original line already has one or more backslashes immediately before the tag, add one more. The parser removes exactly one framing escape; tags mentioned inline need no escaping.\n\n```xml\n<translation>\n(Complete translation of the source document)\n</translation>\n\n<review>\n(Self-review notes, one correction per line with category tag, e.g.)\n- [Tone] \"旁挂记录\" → \"伴随记录\"（生造词）\n- [Sentence] 第 3 段补充逗号断句\n- [Punctuation] 两处破折号替换为冒号\n- 无修正\n</review>\n\n<final>\n(Final translation after corrections)\n</final>\n```\n\n## Self-Review Instructions\n\nAfter writing `<translation>`, re-read it in the target language only, without looking at the source. Check by category:\n\n**Structure**\n- Is the heading hierarchy, list shape, and code block content identical to the source?\n- Are ALL comments inside code blocks left untranslated (byte-identical to source)?\n- Is the language switcher line correctly flipped (not copied from source)?\n- Are link targets preserved, and are spaces after bold markers present only before Latin letters, digits, or CJK ideographs?\n- Are wrapper-tag lines inside section bodies escaped with one additional backslash?\n\n**Tone & Style**\n- Does every sentence read as if originally written by a native speaker?\n- Is there any colloquial, casual, or overly informal phrasing?\n\n**Sentence Structure**\n- Are there run-on sentences that need breaking?\n- Are there stiff passive constructions that should be converted to active voice?\n\n**Word Choice**\n- Are there overly literal translations that sound unnatural?\n- Is the same target-language word used to translate two distinct source concepts?\n- Is any slang or internal jargon present?\n\n**Terminology**\n- For a Chinese target, are first-occurrence glosses correctly applied (not missing, not repeated)? For an English target, are Chinese glosses absent?\n- Are any \"不要译作\" forbidden translations present?\n- For unlisted terms, does a Chinese target use established Chinese precedent or retain the source term as pending, and does an English target use established English terminology or preserve only an ambiguous source term with a short English gloss?\n\n**Punctuation** (when target is Chinese)\n- Are there em-dashes that should be replaced with colons, periods, or commas?\n- Are list items ending with commas instead of semicolons?\n- Do RFC 2119 keywords preserve the source emphasis exactly?\n\nRecord corrections in `<review>` with category tags. Then output the corrected version in `<final>`. If no corrections are needed, write \"无修正\" in `<review>` and copy the translation unchanged into `<final>`.\n\n## Examples\n\nBelow are representative examples of common problems and their corrections. Follow the \"Good\" versions.\n\n### Colloquial verb → Professional verb\n- Source: `The repo pins pnpm@11.7.0 in package.json`\n- Bad: `仓库在 package.json 中钉住 pnpm@11.7.0`\n- Good: `该仓库在 package.json 中固定使用 pnpm@11.7.0`\n\n### Run-on sentence → Natural phrasing with pause\n- Source: `Read docs/architecture.md before changing anything under packages/.`\n- Bad: `改动 packages/ 下的任何东西之前先读 docs/architecture.md。`\n- Good: `在修改 packages/ 目录下的任何内容之前，请先阅读 docs/architecture.md。`\n\n### Stiff passive voice → Active and natural\n- Source: `a green gate means the pair was confirmed consistent at these exact contents, not that the confirmation was sound.`\n- Bad: `门禁绿意味着这对文档曾在当前内容上被确认一致，不意味着这次确认本身是对的。`\n- Good: `门禁通过意味着这组文档在当前内容上的一致性得到了确认，不代表确认本身正确可靠。`\n\n### Invented word → Natural expression\n- Source: `A sidecar record of both blob hashes makes consistency checkable`\n- Bad: `旁挂记录两侧 blob hash，使一致性可检查`\n- Good: `伴随记录保存两侧 blob hash，使一致性可检查`\n\n### Em-dash → Colon/period\n- Source: `FIXME — an issue that should block a new release. A release should not ship with an open FIXME unless reviewers explicitly agree the change can be merged anyway.`\n- Bad: `FIXME——应当阻塞新版本发布的问题。除非评审者明确同意可以照常合入，发布不应带着未解决的 FIXME 出门。`\n- Good: `FIXME：应当阻塞新版本发布的问题。除非评审者明确同意该更改可以合并，否则发布版本不应包含未解决的 FIXME。`\n\n### Overly literal → Meaningful rendering\n- Source: `awkward phrasing is easier to hear without the source anchoring you`\n- Bad: `没有源文锚着，别扭的表述更容易被听出来`\n- Good: `不对照原文时，更容易察觉别扭的表达`\n\n### Terminology — do not translate what should be kept in English\n- Source: `typed service seams, and explicit extension points`\n- Bad: `类型化的服务 seam（扩展点）与显式扩展点`\n- Good: `类型化的服务 seam 与显式扩展点`\n\n### Slang/jargon → Professional phrasing\n- Source: `The committed agent workflow lives in .agents/skills/dsh-translate-docs`\n- Bad: `进仓的 agent 工作流见 .agents/skills/dsh-translate-docs`\n- Good: `仓库内置的 agent 工作流见 .agents/skills/dsh-translate-docs`\n\n### \"For humans\" — translate the intent, not the word\n- Source: `For humans, start with the development guide`\n- Bad: `对于人工读者，请先从开发指南开始`（\"人工读者\"生硬）\n- Good: `面向开发者：请先阅读开发指南`（\"开发者\"自然，且中文里冒号在此处更自然）\n\n### Code block comments — NEVER translate\n- Source code block contains: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)`\n- Bad: `# 全屏 TUI coding agent（需要 DEEPSEEK_API_KEY）`\n- Good: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)` (keep exactly as-is, byte-for-byte)\n\n### Language switcher — flip direction\n- Source file (English) has: `English | [中文](README.zh.md)`\n- Bad (copying source unchanged): `English | [中文](README.zh.md)`\n- Good (flipped for Chinese file): `[English](README.md) | 中文`\n\n---\n\nNow translate the following document:"

CI covers 22.19, 24, and 26; see the [Node engine floor Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md).\n- Corepack-enabled pnpm. The repo pins `pnpm@11.7.0` in `package.json`; run `corepack enable` if `pnpm --version` does not resolve through Corepack.\n- Git.\n- Optional: a DeepSeek API key for the TUI/Headless/ACP agent demos and real-API e2e tests.\n\n## First-time setup\n\nInstall dependencies from the repo root:\n\n```sh\npnpm install\n```\n\nThe install also runs the root `postinstall` script, which installs lefthook from the repo dev dependency through `scripts/install-lefthook.mjs`; the wrapper script uses lefthook's reviewed `--force` mode so linked worktrees with an existing `core.hooksPath` do not fail normal `pnpm run …` commands.\n\nIf hooks are missing because dependencies were restored from cache or `postinstall` was skipped, install them manually:\n\n```sh\npnpm exec lefthook install --force\n```\n\nRun typecheck once after a fresh clone:\n\n```sh\npnpm run typecheck\n```\n\nThat first typecheck runs the whole-repo `tsc -b` graph: it emits every package/vendor `lib/types` and checks examples, tests, and scripts through the two no-emit aggregates described below.\n\n## TypeScript project layout\n\nThe repository's TypeScript configuration has exactly three roles; every tsconfig file plays one of them.\n\n| File | Role | Forms a program? |\n|---|---|---|\n| `tsconfig.json` | Solution root: `extends` base, `files: []`, references to the two aggregates. The whole-repo `tsc -b tsconfig.json` graph, the tsserver discovery entry, and — through the inherited `paths` — the resolution config for tsx running `examples/` and `scripts/` (their nearest tsconfig is this file). | No |\n| `tsconfig.host.json` | Host aggregate: host-side packages (via references), examples, tests, scripts, website. Excludes `packages/client`. | Yes |\n| `tsconfig.client.json` | Client aggregate: `packages/client/*` packages and their tests, `apps/web`. | Yes |\n| `tsconfig.base.json` | Shared compilerOptions and the source `paths` map. Also the resolution facade the vitest configs point vite-tsconfig-paths at: it has no `include`, so its `paths` apply to every importer. | No |\n| `tsconfig.base.client.json` | Browser compiler shape (`jsx`, DOM libs, `types: []`) extended by the client aggregate and every `packages/client/*` package. | No |\n\nHost and client stay two aggregate programs because both sides declaration-merge the cordis `Context` interface under the same keys with different services; one program seeing both merges reports a collision. The collision exists only inside a `ts.Program` — module resolution never triggers it — which is why the solution may reference both aggregates and one paths facade may span both sides. Two disciplines follow:\n\n- `tsconfig.base.json` never gains `include` or `files`: they would leak into every extending package project and narrow the facade's match-all scope.\n- A script that builds a repo-wide `ts.Program` seeds `tsconfig.host.json` or `tsconfig.client.json` explicitly — never the root solution, because flattening both aggregates into one program collides the `Context` merges. Program-backed generators and gates (`scripts/ts-project.ts` consumers, doc-typecheck standalone mode) are host-only by decision; the client side gains program-backed tooling only with a concrete need.\n\nStatic analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly. Decision record: [solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md); the tsc-first emit pipeline is the [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md).\n\nIf a relevant local check consumes built package output, build once first:\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` includes `publint`, which validates package entrypoints against the built `lib/*.js` files, and `verify-node-next-types`, which validates built declarations against a temporary NodeNext consumer. A fresh worktree has no bundled JS or declarations until `pnpm run build` runs; ordinary commits and pushes do not require that build unless their selected checks consume it.\n\n## Environment variables\n\nThe real DeepSeek adapter and key-backed agent demos read credentials from the environment or from a gitignored `.env` at the repo root:\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` is optional and defaults to the public API. Never commit real credentials. The real-API e2e suites self-skip when `DEEPSEEK_API_KEY` is not set.\n\n## Git hooks\n\nlefthook is configured in `lefthook.yml` as a fast local checkpoint:\n\n- `pre-commit` runs staged-file ESLint fixes, checks the staged diff for whitespace errors, and runs the vendor manifest guard.\n- `pre-push` runs only the incremental repository typecheck (`tsc -b` over the root solution, covering both the host and client aggregates).\n\nThe vendor manifest guard checks that changes under `vendor/*/src` are staged with the matching `vendor/README.md` manifest update. See `vendor/README.md` before editing vendored code.\n\nThe hooks intentionally do not run tests, snapshots, documentation checks, builds, or hygiene. Contributors run the [checks relevant to the changed behavior](../AGENTS.md#run-relevant-checks-locally) once; CI owns exhaustive coverage, built-artifact smokes, and the Node 22.19, 24, and 26 compatibility matrix.\n\nContributors can opt into the comprehensive local gate set with `pnpm run check:all`. The command is independent of both Git hooks and is not an agent instruction.\n\n## CI gates\n\nThe keyless [CI workflow](../.github/workflows/ci.yml) groups independent gates into broad lanes and runs a smaller compatibility signal across supported Node versions. Artifact consumers wait for one build within their lane. The separate real-API workflow runs `pnpm run test:e2e` with its configured worker bound. See [scripts/run-gates.ts](../scripts/run-gates.ts) and the workflow files for the current gate and job inventory.\n\n## Daily commands\n\nUse these from the repo root:\n\n```sh\npnpm run test # unit tests\npnpm run test:coverage # unit tests with per-file coverage gates\npnpm run test:e2e # real-API tests; self-skips without DEEPSEEK_API_KEY\npnpm run check:all # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck # tsc -b over the root solution: emits package/vendor lib/types, checks both aggregates\npnpm run lint # eslint .\npnpm run lint:fix # eslint . --fix\npnpm run doc-typecheck # compile checked TypeScript snippets in Markdown docs\npnpm run gen-cordis-catalog # regenerate docs/cordis-catalog/events.md + services.md from source\npnpm run verify-cordis-catalog # fail if either cordis catalog is stale\npnpm run verify-export-jsdoc # fail if a module-level package export lacks complete JSDoc\npnpm run gen-doc-graphs # regenerate generated relationship docs from source and curated graph definitions\npnpm run verify-doc-graphs # fail if generated relationship docs are stale\npnpm run verify-md-wrap # fail on hard-wrapped prose paragraphs in docs/README markdown\npnpm run verify-mermaid # fail if a ```mermaid diagram has invalid Mermaid syntax\npnpm run verify-type-equiv # fail if a ```ts type-equiv doc block drifts from its source type\npnpm run verify-doc-budgets # fail if a budgeted standing doc exceeds its word ceiling\npnpm run doc-sync # all Markdown/doc gates, scheduled concurrently; the doc-sync leaf list in scripts/run-gates.ts is the full list\npnpm run gen-module-graph # regenerate docs/module-graph.md from package peerDeps\npnpm run verify-module-graph # fail if docs/module-graph.md is stale\npnpm run build # emit lib/types intermediates, then bundle lib/index.* runtime files\npnpm run verify-node-next-types # fail if built declarations are not NodeNext-consumable\npnpm run hygiene # knip, publint, workspace constraints, and NodeNext declaration check\n```\n\nWhen changing package public behavior, update the relevant README or JSDoc in the same change. `pnpm run doc-sync` catches checked TypeScript snippets, generated doc freshness, markdown wrap/link drift, type equivalence, translation pairing, Mermaid syntax, and doc budgets, but broader prose/API sync still needs review.\n\n## Demos\n\nThe one-shot Headless coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:headless \"summarize this workspace\"\n```\n\nThe full-screen interactive coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:tui\n```\n\nThe self-referential cordis-agent demo can inspect and modify its live plugin runtime and needs the same credentials:\n\n```sh\npnpm run demo:cordis\n```\n\nThe ACP server agent demo exposes the agent over JSON-RPC stdio and also needs `DEEPSEEK_API_KEY`:\n\n```sh\npnpm run demo:acp\n```\n\n## TODO markers\n\nUse one of three comment tags to flag known issues in the code, ordered by urgency:\n\n- `FIXME` — an issue that should block a new release. A release should not ship with an open `FIXME` unless reviewers explicitly agree the change can be merged anyway.\n- `TODO` — an issue that should be fixed soon, once we have the resources.\n- `XXX` — an issue that we may fix someday; lowest priority, no commitment.\n\nPick the tag that matches the urgency so anyone scanning the code can tell a release blocker from a someday-maybe.\n\n## Documenting types verbatim (`ts type-equiv`)\n\nThe [core data structures](core-data-structures/core.md) docs paste source-equivalent declarations together with their original JSDoc so a reader sees the exact shape and source contract. To keep a paste from drifting when source changes, fence it as ` ```ts type-equiv ` (instead of ` ```ts `) and register it in `scripts/type-equiv.manifest.json` with the source file and symbol it mirrors:\n\n```json\n{ \"doc\": \"docs/core-data-structures/session.md\", \"symbol\": \"SessionEvent\", \"source\": \"packages/core/session/src/types.ts\" }\n```\n\n`pnpm run verify-type-equiv` (part of `doc-sync`) then extracts that symbol's declaration and attached JSDoc from source via the TypeScript parser and asserts the block matches both. For a class whose implementation bodies do not belong in the catalog, use ` ```ts public-api ` and set `\"projection\": \"public-api\"`; the checked projection retains the public fields, constructor, accessors, methods, and original class/member JSDoc while omitting bodies and private or protected members. Comparison ignores whitespace and non-JSDoc comments but requires every original JSDoc comment, including member documentation, so readers see the source contract beside the exact shape. The gate also enforces a 1:1 correspondence by document, symbol, and projection, so a block can't go silently unchecked and a stale entry can't linger. `doc-typecheck` skips both fence kinds (they aren't standalone-compilable) and excludes them from its opt-out ratio. When you change a documented declaration or its JSDoc, the gate fails until you update the paste; when you add or remove a block, update the manifest in the same change.\n\n## Architecture context\n\nRead `docs/architecture.md` before changing anything under `packages/`. The codebase is built around Cordis plugins, event-sourced sessions, typed service seams, and explicit extension points.\n"
+ "content": "# Development guide\n\nEnglish | [中文](development.zh.md)\n\nThis onboarding guide helps project contributors get started with the local environment, daily workflow, and CI flow; see the Agent Notes for design rationale and technical trade-offs.\n\n## Prerequisites\n\n- Node.js supports 22.19+ and 24+. CI covers 22.19, 24, and 26; see the [Node engine floor Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md).\n- Corepack-enabled pnpm. The repo pins `pnpm@11.7.0` in `package.json`; run `corepack enable` if `pnpm --version` does not resolve through Corepack.\n- Git.\n- Optional: a DeepSeek API key for the TUI, headless, and ACP automation demos and real-API e2e tests.\n\n## First-time setup\n\nInstall dependencies from the repo root:\n\n```sh\npnpm install\n```\n\nThe install also runs the root `postinstall` script, which installs lefthook from the repo dev dependency through `scripts/install-lefthook.mjs`; the wrapper script uses lefthook's reviewed `--force` mode so linked worktrees with an existing `core.hooksPath` do not fail normal `pnpm run …` commands.\n\nIf hooks are missing because dependencies were restored from cache or `postinstall` was skipped, install them manually:\n\n```sh\npnpm exec lefthook install --force\n```\n\nRun typecheck once after a fresh clone:\n\n```sh\npnpm run typecheck\n```\n\nThat first typecheck runs the whole-repo `tsc -b` graph: it emits every package/vendor `lib/types` and checks examples, tests, and scripts through the two no-emit aggregates described below.\n\n## TypeScript project layout\n\nThe repository's TypeScript configuration has exactly three roles; every tsconfig file plays one of them.\n\n| File | Role | Forms a program? |\n|---|---|---|\n| `tsconfig.json` | Solution root: `extends` base, `files: []`, references to the two aggregates. The whole-repo `tsc -b tsconfig.json` graph, the tsserver discovery entry, and — through the inherited `paths` — the resolution config for tsx running `examples/` and `scripts/` (their nearest tsconfig is this file). | No |\n| `tsconfig.host.json` | Host aggregate: host-side packages (via references), examples, tests, scripts, website. Excludes `packages/client`. | Yes |\n| `tsconfig.client.json` | Client aggregate: `packages/client/*` packages and their tests, `apps/web`. | Yes |\n| `tsconfig.base.json` | Shared compilerOptions and the source `paths` map. Also the resolution facade the vitest configs point vite-tsconfig-paths at: it has no `include`, so its `paths` apply to every importer. | No |\n| `tsconfig.base.client.json` | Browser compiler shape (`jsx`, DOM libs, `types: []`) extended by the client aggregate and every `packages/client/*` package. | No |\n\nHost and client stay two aggregate programs because both sides declaration-merge the cordis `Context` interface under the same keys with different services; one program seeing both merges reports a collision. The collision exists only inside a `ts.Program` — module resolution never triggers it — which is why the solution may reference both aggregates and one paths facade may span both sides. Two disciplines follow:\n\n- `tsconfig.base.json` never gains `include` or `files`: they would leak into every extending package project and narrow the facade's match-all scope.\n- A script that builds a repo-wide `ts.Program` seeds `tsconfig.host.json` or `tsconfig.client.json` explicitly — never the root solution, because flattening both aggregates into one program collides the `Context` merges. Program-backed generators and gates (`scripts/ts-project.ts` consumers, doc-typecheck standalone mode) are host-only by decision; the client side gains program-backed tooling only with a concrete need.\n\nStatic analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly. Decision record: [solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md); the tsc-first emit pipeline is the [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md).\n\nIf a relevant local check consumes built package output, build once first:\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` includes `publint`, which validates package entrypoints against the built `lib/*.js` files, and `verify-node-next-types`, which validates built declarations against a temporary NodeNext consumer. A fresh worktree has no bundled JS or declarations until `pnpm run build` runs; ordinary commits and pushes do not require that build unless their selected checks consume it.\n\n## Environment variables\n\nThe real DeepSeek adapter and key-backed agent demos read credentials from the environment or from a gitignored `.env` at the repo root:\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` is optional and defaults to the public API. Never commit real credentials. The real-API e2e suites self-skip when `DEEPSEEK_API_KEY` is not set.\n\n## Git hooks\n\nlefthook is configured in `lefthook.yml` as a fast local checkpoint:\n\n- `pre-commit` runs staged-file ESLint fixes, checks the staged diff for whitespace errors, and runs the vendor manifest guard.\n- `pre-push` runs only the incremental repository typecheck (`tsc -b` over the root solution, covering both the host and client aggregates).\n\nThe vendor manifest guard checks that changes under `vendor/*/src` are staged with the matching `vendor/README.md` manifest update. See `vendor/README.md` before editing vendored code.\n\nThe hooks intentionally do not run tests, snapshots, documentation checks, builds, or hygiene. Contributors run the [checks relevant to the changed behavior](../AGENTS.md#run-relevant-checks-locally) once; CI owns exhaustive coverage, built-artifact smokes, and the Node 22.19, 24, and 26 compatibility matrix.\n\nContributors can opt into the comprehensive local gate set with `pnpm run check:all`. The command is independent of both Git hooks and is not an agent instruction.\n\n## CI gates\n\nThe keyless [CI workflow](../.github/workflows/ci.yml) groups independent gates into broad lanes and runs a smaller compatibility signal across supported Node versions. Artifact consumers wait for one build within their lane. The separate real-API workflow runs `pnpm run test:e2e` with its configured worker bound. See [scripts/run-gates.ts](../scripts/run-gates.ts) and the workflow files for the current gate and job inventory.\n\n## Daily commands\n\nUse these from the repo root:\n\n```sh\npnpm run test # unit tests\npnpm run test:coverage # unit tests with per-file coverage gates\npnpm run test:e2e # real-API tests; self-skips without DEEPSEEK_API_KEY\npnpm run check:all # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck # tsc -b over the root solution: emits package/vendor lib/types, checks both aggregates\npnpm run lint # eslint .\npnpm run lint:fix # eslint . --fix\npnpm run doc-typecheck # compile checked TypeScript snippets in Markdown docs\npnpm run gen-cordis-catalog # regenerate docs/cordis-catalog/events.md + services.md from source\npnpm run verify-cordis-catalog # fail if either cordis catalog is stale\npnpm run verify-export-jsdoc # fail if a module-level package export lacks complete JSDoc\npnpm run gen-doc-graphs # regenerate generated relationship docs from source and curated graph definitions\npnpm run verify-doc-graphs # fail if generated relationship docs are stale\npnpm run verify-md-wrap # fail on hard-wrapped prose paragraphs in docs/README markdown\npnpm run verify-mermaid # fail if a ```mermaid diagram has invalid Mermaid syntax\npnpm run verify-type-equiv # fail if a ```ts type-equiv doc block drifts from its source type\npnpm run verify-doc-budgets # fail if a budgeted standing doc exceeds its word ceiling\npnpm run doc-sync # all Markdown/doc gates, scheduled concurrently; the doc-sync leaf list in scripts/run-gates.ts is the full list\npnpm run gen-module-graph # regenerate docs/module-graph.md from package peerDeps\npnpm run verify-module-graph # fail if docs/module-graph.md is stale\npnpm run build # emit lib/types intermediates, then bundle lib/index.* runtime files\npnpm run verify-node-next-types # fail if built declarations are not NodeNext-consumable\npnpm run hygiene # knip, publint, workspace constraints, and NodeNext declaration check\n```\n\nWhen changing package public behavior, update the relevant README or JSDoc in the same change. `pnpm run doc-sync` catches checked TypeScript snippets, generated doc freshness, markdown wrap/link drift, type equivalence, translation pairing, Mermaid syntax, and doc budgets, but broader prose/API sync still needs review.\n\n## Demos\n\nThe one-shot Headless coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:headless \"summarize this workspace\"\n```\n\nThe full-screen interactive coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:tui\n```\n\nThe self-referential cordis-agent demo can inspect and modify its live plugin runtime and needs the same credentials:\n\n```sh\npnpm run demo:cordis\n```\n\nThe ACP automation server exposes fresh agent sessions over JSON-RPC stdio and also needs `DEEPSEEK_API_KEY`:\n\n```sh\npnpm run demo:acp\n```\n\n## TODO markers\n\nUse one of three comment tags to flag known issues in the code, ordered by urgency:\n\n- `FIXME` — an issue that should block a new release.

+ "content": "# 开发指南\n\n[English](development.md) | 中文\n\n本指南覆盖参与 DeepSeek Harness 开发所需的本地环境搭建、日常工作流与 CI 流程；设计动机与技术权衡请查阅相应 Agent Note。\n\n## 前置条件\n\n- Node.js 支持 22.19+ 与 24+。CI 覆盖 22.19、24 和 26；见 [Node 引擎下限 Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md)。\n- 启用了 Corepack 的 pnpm。仓库在 `package.json` 中固定使用 `pnpm@11.7.0`；如果 `pnpm --version` 无法通过 Corepack 解析，请先运行 `corepack enable`。\n- Git。\n- 可选：一个 DeepSeek API key，用于 TUI、headless 和 ACP（Agent Client Protocol）自动化 agent（智能体）演示以及真实 API 的 e2e 测试。\n\n## 首次搭建\n\n在仓库根目录安装依赖：\n\n```sh\npnpm install\n```\n\n安装过程同时会运行根目录的 `postinstall` 脚本，该脚本通过 `scripts/install-lefthook.mjs` 从仓库 dev 依赖安装 lefthook。包装脚本使用 lefthook 经过评审的 `--force` 模式，确保已存在 `core.hooksPath` 的关联 worktree 不会导致正常的 `pnpm run …` 命令失败。\n\n如果依赖是从缓存恢复或 `postinstall` 被跳过而导致缺少钩子，请手动安装：\n\n```sh\npnpm exec lefthook install --force\n```\n\n新克隆后请先运行一次类型检查：\n\n```sh\npnpm run typecheck\n```\n\n首次类型检查会执行全仓 `tsc -b tsconfig.json` 图：发射每个 package/vendor 的 `lib/types`，并通过下述两个 no-emit 聚合检查示例、测试和脚本。\n\n## TypeScript 项目布局\n\n仓库的 TypeScript 配置只有三种角色；每个 tsconfig 文件恰好扮演其中一种。\n\n| 文件 | 角色 | 是否构成 program？ |\n|---|---|---|\n| `tsconfig.json` | solution 根：`extends` base、`files: []`、引用两个聚合。全仓 `tsc -b tsconfig.json` 图、tsserver 发现入口，并经继承的 `paths` 充当 tsx 运行 `examples/` 与 `scripts/` 时的解析配置（它们最近的 tsconfig 就是此文件）。 | 否 |\n| `tsconfig.host.json` | host 聚合：host 侧各包（经 references）、示例、测试、脚本、website。排除 `packages/client`。 | 是 |\n| `tsconfig.client.json` | client 聚合：`packages/client/*` 各包及其测试、`apps/web`。 | 是 |\n| `tsconfig.base.json` | 共享 compilerOptions 与源码 `paths` 映射。同时是各 vitest 配置让 vite-tsconfig-paths 指向的解析门面：它没有 `include`，因此其 `paths` 适用于任何 importer。 | 否 |\n| `tsconfig.base.client.json` | 浏览器编译形状（`jsx`、DOM lib、`types: []`），由 client 聚合和每个 `packages/client/*` 包 extends。 | 否 |\n\nhost 与 client 保持两个聚合 program，是因为两侧在相同键下以不同服务对 cordis `Context` 接口做声明合并；单一 program 同时看到两份合并会报冲突。这种冲突只存在于 `ts.Program` 内部——模块解析永远不会触发它——所以 solution 可以同时引用两个聚合，一个 paths 门面也可以横跨两侧。由此推出两条纪律：\n\n- `tsconfig.base.json` 永不添加 `include` 或 `files`：它们会泄漏进每个 extends 它的包项目，并收窄门面的全匹配范围。\n- 构造全仓 `ts.Program` 的脚本显式种子 `tsconfig.host.json` 或 `tsconfig.client.json`——永不种子根 solution，因为把两个聚合展平进一个 program 会撞上 `Context` 合并冲突。基于 program 的生成器与门禁（`scripts/ts-project.ts` 的消费者、doc-typecheck standalone 模式）按决策仅覆盖 host 侧；client 侧只在出现真实需求时再获得基于 program 的工具。\n\n静态分析和测试通过 base 的 `paths` 映射把工作区 import 解析到 `src`，且必须在干净树上通过；消费构建产物 `lib/` 的门禁显式声明该依赖。决策记录：[solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md)；tsc-first 发射管线见 [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md)。\n\n如果相关的本地检查需要使用构建后的包产物，请先构建一次：\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` 包含 `publint`（用构建出的 `lib/*.js` 文件校验 package 入口点）和 `verify-node-next-types`（用一个临时的 NodeNext 消费方校验构建出的声明文件）。新 worktree 在 `pnpm run build` 运行之前没有打包的 JS 和声明文件；普通提交和推送无需构建，除非所选检查会使用这些产物。\n\n## 环境变量\n\n真实的 DeepSeek 适配器和需要密钥的 agent 演示从环境变量或仓库根目录一个被 gitignore 的 `.env` 文件读取凭证：\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` 可选，默认为公开 API。请勿提交真实凭证。未设置 `DEEPSEEK_API_KEY` 时，真实 API 的 e2e 套件会自动跳过。\n\n## Git 钩子\n\nlefthook 在 `lefthook.yml` 中配置，作为快速的本地检查点：\n\n- `pre-commit` 运行对暂存文件的 ESLint 修复，检查暂存 diff 中的空白错误，并运行 vendor manifest（元数据清单）守卫；\n- `pre-push` 只运行仓库增量类型检查（对根 solution 执行 `tsc -b`，覆盖 host 与 client 两个聚合）。\n\nvendor manifest 守卫检查 `vendor/*/src` 下的改动是否连同对应的 `vendor/README.md` manifest 更新一起暂存。请在编辑 vendor 代码前先阅读 `vendor/README.md`。\n\n这些钩子有意不运行测试、快照、文档检查、构建或 `hygiene`。贡献者只运行一次[与改动行为相关的检查](../AGENTS.md#run-relevant-checks-locally)；CI 负责全量覆盖率门禁、构建产物冒烟测试，以及 Node 22.19、24 和 26 兼容性矩阵。\n\n贡献者可以选择运行 `pnpm run check:all`，执行全面的本地门禁集。该命令独立于两个 Git 钩子，也不是对 agent 的指令。\n\n## CI 门禁\n\nkeyless [CI 工作流](../.github/workflows/ci.yml) 将独立门禁分组到若干宽粒度 lane，并在受支持的 Node 版本上运行一组较小的兼容性检查。产物消费方在各自 lane 内等待一次 build。单独的真实 API 工作流按其配置的 worker 上限运行 `pnpm run test:e2e`。当前门禁和 job 清单以 [scripts/run-gates.ts](../scripts/run-gates.ts) 和工作流文件为准。\n\n## 日常命令\n\n在仓库根目录使用：\n\n```sh\npnpm run test # unit tests\npnpm run test:coverage # unit tests with per-file coverage gates\npnpm run test:e2e # real-API tests; self-skips without DEEPSEEK_API_KEY\npnpm run check:all # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck # tsc -b over the root solution: emits package/vendor lib/types, checks both aggregates\npnpm run lint # eslint .\npnpm run lint:fix # eslint . --fix\npnpm run doc-typecheck # compile checked TypeScript snippets in Markdown docs\npnpm run gen-cordis-catalog # regenerate docs/cordis-catalog/events.md + services.md from source\npnpm run verify-cordis-catalog # fail if either cordis catalog is stale\npnpm run verify-export-jsdoc # fail if a module-level package export lacks complete JSDoc\npnpm run gen-doc-graphs # regenerate generated relationship docs from source and curated graph definitions\npnpm run verify-doc-graphs # fail if generated relationship docs are stale\npnpm run verify-md-wrap # fail on hard-wrapped prose paragraphs in docs/README markdown\npnpm run verify-mermaid # fail if a ```mermaid diagram has invalid Mermaid syntax\npnpm run verify-type-equiv # fail if a ```ts type-equiv doc block drifts from its source type\npnpm run verify-doc-budgets # fail if a budgeted standing doc exceeds its word ceiling\npnpm run doc-sync # all Markdown/doc gates, scheduled concurrently;

- "content": "# Bilingual documentation\n\nEnglish | [中文](README.zh.md)\n\nThis repo's documentation is read by people and agents both inside and outside the company, so the README, Agent Notes, and docs tree are maintained in English and Simplified Chinese. This page defines the pairing contract, the enforcement gate, and the rollout policy; [translation-rules.md](translation-rules.md) defines how to translate; [terminology.md](terminology.md) is the terminology source of truth. The committed agent workflow lives in [.agents/skills/dsh-translate-docs](../../.agents/skills/dsh-translate-docs/SKILL.md).\n\n## The pairing contract\n\n- **Both languages carry equal authority.** A document may be authored and reviewed in either language first — a Chinese-first Agent Note is as legitimate as an English-first one — and the counterpart is translated from it. Neither file outranks the other; what binds them is that they must say the same thing.\n- **A pair is three sibling files.** The English `foo.md`, the Chinese `foo.zh.md`, and a consistency record `foo.i18n.yaml`, all in the same directory. No locale directories, no separate translation repo, no interleaved bilingual files. Pairs merge whole: a PR never lands one language without the other two files.\n- **The consistency record.** `foo.i18n.yaml` holds the full git blob hash of each side as of the last time the two were confirmed to say the same thing:\n\n ```yaml\n foo.md: 3f786850e387550fdab836ed7e6dc881de23001b\n foo.zh.md: 89e6c98d92887913cadf06b2adb97f26cde4849b\n ```\n\n Blob hashes, not commit hashes, so the record is computable for files edited in the same PR (`git hash-object foo.md`) and consistency is a pure content comparison. The recorded hash also recovers the exact last-confirmed text of either side (`git cat-file -p <hash>`), so an out-of-sync pair is updated by diffing the edited side against its last-confirmed state and patching the counterpart minimally — never by re-translating whole files. After bringing the pair back in line, `pnpm run verify-translation-pairing --write` re-records both hashes; that yaml diff is the reviewable act of confirming consistency.\n- **Language switcher.** Both files link to each other immediately after their H1 heading: the English file carries `English | [中文](foo.zh.md)` and the Chinese file carries `[English](foo.md) | 中文`.\n- **Structure mirrors the counterpart.** Heading depths and order, list kinds, ordered-list starts, list item counts, table row and column counts, link targets, and verbatim code blocks match one to one across the pair — see [translation-rules.md](translation-rules.md) for the full preservation rules. Existing Markdown gates apply to `.zh.md` files unchanged (`verify-md-wrap`, `verify-md-links`).\n\n## The gate: verify-translation-pairing\n\n`pnpm run verify-translation-pairing` (part of `doc-sync`, which contributors run locally for documentation changes and CI runs exhaustively) enforces the contract mechanically:\n\n1. Every file listed as `required` in [scripts/translation-pairing.manifest.json](../../scripts/translation-pairing.manifest.json) has a complete pair.\n2. Every pair that exists at all — required or not — is complete and consistent: all three files present, each side's current blob hash equals the recorded one (editing either side without re-confirming the pair goes red), both sides carry the language switcher, and the structural signatures match in order — heading depths, verbatim code blocks (info string and content), table row and column counts, list kinds, ordered-list starts, item counts, and every link target apart from the switcher.\n3. Files listed as `excluded` have no `.zh.md` and no `.i18n.yaml` at all.\n4. Every date-named document (`yyyy-mm-dd-*.md`) dated on or after the manifest's `requiredSince` cutoff has a complete pair — new date-named Agent Notes merge bilingual from birth.\n\n`pnpm run verify-translation-pairing --list` prints the current pairing state of every document in scope — missing, out-of-sync, or ok — and is the work list for translation batches. It never fails; it reports.\n\nThe practical rule this gate creates: **when a PR edits either side of a paired document, the same PR updates the counterpart and re-records the pair** (run the [dsh-translate-docs](../../.agents/skills/dsh-translate-docs/SKILL.md) skill, then `--write`), exactly like the repo's existing doc-sync rule for code and READMEs. A PR that leaves a pair out of sync goes red in CI.\n\nThe gate's limit, stated plainly: **a green gate means the pair was confirmed consistent at these exact contents, not that the confirmation was sound.** It checks hashes and shape; it cannot judge whether the two sides actually say the same thing, or whether the wording is accurate, well-termed, and natural — that is the reviewer's half of the contract, per [translation-rules.md](translation-rules.md). A re-recorded pair with a sloppy counterpart passes the gate; it must not pass review.\n\n## Scope, exclusions, and rollout\n\n**Scope**: the root `README.md`, everything under `.agents/notes/**`, `docs/**`, and `python/**`. Package READMEs (`packages/**`) join the scope in a later batch.\n\n**Excluded** (never paired, and the gate rejects a `.zh.md` or `.i18n.yaml` for them):\n\n- `docs/cordis-catalog/`, `docs/tool-catalog/`, `docs/config-catalog.md`, `docs/persistence-catalog.md`, and `docs/module-graph.md` — generated files; their generators emit English only today, so a hand-written translation would go stale on every regeneration. The planned follow-up is to teach the generators to emit Chinese alongside English, at which point these leave the exclusion list.\n- `docs/AGENTS.md` and `.agents/notes/**/AGENTS.md` — agent instructions, maintained in English only like the root `AGENTS.md`.\n- `docs/i18n/terminology.md` and [style-samples.md](style-samples.md) — both are bilingual by construction.\n- [translation-prompt.md](translation-prompt.md) — the automated pipeline's prompt template; its body is machine-consumed verbatim, so a paired translation would change pipeline behavior.\n\n**Rollout**: a date-named document (`yyyy-mm-dd-*.md`, i.e. an Agent Note) dated on or after the manifest's `requiredSince` cutoff must merge with its pair. Earlier dates are backlog, including files created on the cutoff's eve. An Agent Note filename records its first-proposed date, so backdating past the cutoff is a review-visible violation. The manifest's `required` list is the current enforcement frontier, not the goal of full coverage. Translation batches add paths to `required`, ratcheting the gate forward. Unlisted documents remain visible in `--list`, while every existing pair is governed by the full contract. Because later edits must update both sides, expand `required` only as fast as translation review can support.\n\n## Division of labor\n\nCounterparts here are produced by an agent running [dsh-translate-docs](../../.agents/skills/dsh-translate-docs/SKILL.md) and reviewed by a human — inference is cheap here, review attention is the scarce resource. The gate checks pair completeness, recorded hashes, switchers, and its documented structural signature. Review still owns translation quality, terminology, and structural requirements that the signature does not encode. The prompt contract is executable: [scripts/translation-prompt.ts](../../scripts/translation-prompt.ts) renders the committed template (terminology injected; the template carries its own calibrated rules) into either direction and parses the three-section response, while `verify-translation-prompt` exercises both render directions and the checked-in example in `doc-sync`.\n"

The planned follow-up is to teach the generators to emit Chinese alongside English, at which point these leave the exclusion list.\n- `docs/AGENTS.md` and `.agents/notes/**/AGENTS.md` — agent instructions, maintained in English only like the root `AGENTS.md`.\n- `docs/i18n/terminology.md` and [style-samples.md](style-samples.md) — both are bilingual by construction.\n- [translation-prompt.md](translation-prompt.md) — the automated pipeline's prompt template; its body is machine-consumed verbatim, so a paired translation would change pipeline behavior.\n\n**Rollout**: a date-named document (`yyyy-mm-dd-*.md`, i.e. an Agent Note) dated on or after the manifest's `requiredSince` cutoff must merge with its pair. Earlier dates are backlog, including files created on the cutoff's eve. An Agent Note filename records its first-proposed date, so backdating past the cutoff is a review-visible violation. The manifest's `required` list is the current enforcement frontier, not the goal of full coverage. Translation batches add paths to `required`, ratcheting the gate forward. Unlisted documents remain visible in `--list`, while every existing pair is governed by the full contract. Because later edits must update both sides, expand `required` only as fast as translation review can support.\n\n## Division of labor\n\nCounterparts here are produced by an agent running [dsh-translate-docs](../../.agents/skills/dsh-translate-docs/SKILL.md) and reviewed by a human — inference is cheap here, review attention is the scarce resource. The gate checks pair completeness, recorded hashes, switchers, and its documented structural signature. Review still owns translation quality, terminology, and structural requirements that the signature does not encode. The prompt contract is executable: [scripts/translation-prompt.ts](../../scripts/translation-prompt.ts) renders the committed template (terminology injected; the template carries its own calibrated rules) into either direction and parses the three-section response, while `verify-translation-prompt` exercises both render directions and the checked-in example in `doc-sync`.\n"

Maintaining a second language by hand, with no mechanism, is how translations rot: one side moves on, the other silently lies, and no gate notices. The repo's standing answer to invariants of this kind is to encode them as a mechanical check (see [quality gates](2026-06-11-quality-gates.md) and [doc-sync enforcement](2026-06-11-doc-sync-enforcement.md)), so the bilingual policy ships with one.\n\n## Decision\n\n- **Paired sibling files with equal authority.** A documentation pair is three sibling files: English `foo.md`, Chinese `foo.zh.md`, and a consistency record `foo.i18n.yaml`. Neither language is canonical — a document may be authored and reviewed Chinese-first and translated to English afterwards, or the reverse; what binds the pair is that both sides must say the same thing, and pairs merge whole (both languages plus the record, never one alone). Policy: [docs/i18n/README.md](../../../../docs/i18n/README.md); translation rules: [docs/i18n/translation-rules.md](../../../../docs/i18n/translation-rules.md); terminology source of truth: [docs/i18n/terminology.md](../../../../docs/i18n/terminology.md).\n- **A sidecar record of both blob hashes makes consistency checkable.** `foo.i18n.yaml` holds the full git blob hash of each side as of the last confirmed-consistent state. An edit to either side without re-confirming the pair is then mechanically detectable as a pure content comparison — no history lookup — and the hashes are computable for files edited in the same PR, which a commit-hash record is not. Re-recording (`verify-translation-pairing --write`) produces a reviewable yaml diff: confirming consistency is an explicit, visible act in the PR.\n- **`verify-translation-pairing` joins `doc-sync`.** The gate ([scripts/verify-translation-pairing.ts](../../../../scripts/verify-translation-pairing.ts)) enforces: required pairs exist, every existing pair is complete (all three files) and consistent (both hashes match, switcher links both ways, structural signatures identical), excluded (generated or bilingual-by-construction) files stay unpaired, and date-named documents on or after the manifest's `requiredSince` cutoff have complete pairs. The `required` list in [scripts/translation-pairing.manifest.json](../../../../scripts/translation-pairing.manifest.json) is a ratchet: each merged translation batch adds its files, so coverage only grows.\n- **Translation is agent work with human review.** The committed workflow is [.agents/skills/dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md), following the same pattern as [dsh-code-review](../../../skills/dsh-code-review/SKILL.md): the skill carries the workflow and defers to the docs as sources of truth. The skill directs the orchestrating agent to delegate translation writing to a subagent.\n\n## Alternatives considered\n\n- **English as the canonical source with a fingerprint inside the translation** — the design first proposed for this Agent Note: `.zh.md` files carried an HTML comment recording the English source's blob hash, and translation flowed EN → ZH only. Revised in review: the team wants Chinese-first authoring (write and review a Chinese Agent Note, then translate to English) with the two languages holding equal authority, which a one-directional canonical model cannot express. The sidecar record covering BOTH sides replaced the in-file one-directional fingerprint; the blob-hash mechanics survived unchanged.\n- **Locale directories (`docs/en/` + `docs/zh/`, the Kubernetes/ECharts model)** — rejected: this repo has no docs-site framework to map locales to routes, moving every English file would churn every existing cross-reference, and `verify-md-links`/`verify-doc-refs` would need path-mapping logic instead of working unchanged.\n- **A separate translation repo (the PingCAP `docs`/`docs-cn` model)** — rejected: right for a docs product with independent release trains, overkill for a monorepo's own documentation; it also puts the translation outside the reach of this repo's gates.\n- **Interleaved bilingual files (single file, both languages)** — rejected: doubles every diff, breaks the one-line-per-paragraph convention's diff ergonomics, and makes partial inconsistency invisible.\n- **Commit-hash records (the MDN `l10n.sourceCommit` model)** — rejected in favor of blob hashes: a same-PR edit has no commit hash yet, so the MDN model cannot express \"consistent as of the state this PR introduces\", and verifying it requires git history instead of file content.\n- **Comparing git timestamps of the pair (no record)** — rejected: formatting-only edits would false-positive, and a counterpart committed after an unrelated edit would false-negative; content identity is the only signal that means what the gate claims.\n\n## Industry precedent\n\nPaired sibling files with locale suffixes are the dominant Chinese big-tech convention (ant-design `index.zh-CN.md`/`index.en-US.md`; arco-design `README.zh-CN.md` with a top-of-file switcher; Apache ShardingSphere's 387 `.cn.md`/`.en.md` pairs) — but none of those repos *enforce* pairing or consistency in CI; the convention holds by review alone. Consistency automation exists outside China: MDN's `l10n.sourceCommit` front-matter fingerprint, Vue's Ryu-Cho action (upstream-commit watcher that opens issues/PRs for stale translations), Kubernetes' localization drift scripts, and Microsoft's Azure co-op-translator (source-hash-driven LLM re-translation in CI). This design combines the two: the Chinese-ecosystem file layout with a hash-pair gate, plus a committed agent skill in place of a bot service.\n\n## Consequences\n\n- Editing either side of a paired document obligates the same PR to update the counterpart and re-record the pair — the gate makes the doc-sync rule bilingual, and CI (not reviewer memory) carries the invariant.\n- Every pair adds a third file to the tree. The record is machine-written (`--write`), so the cost is directory noise, not maintenance effort; in exchange, \"who confirmed these consistent, and when\" is answerable from git blame on the yaml.\n- When the two sides disagree, no mechanical rule picks a winner — the PR review does. That is the price of equal authority, accepted deliberately: the alternative (a canonical language) forbids Chinese-first authoring.\n- Generated docs (`cordis-catalog/`, `tool-catalog/`, `module-graph.md`) are excluded for now; the planned follow-up is to teach their generators to emit Chinese alongside English, at which point they leave the exclusion list.\n- Rollout is incremental by design: documents outside `required` are visible backlog (`--list`), not red CI, so pairs land in reviewable batches without a big-bang PR. A date-named document dated on or after the manifest's `requiredSince` cutoff merges bilingual or not at all, so new date-named Agent Notes do not enlarge that backlog.\n- The recorded hashes double as the update tool (`git cat-file -p <hash>` recovers either side's last-confirmed text for a minimal diff-based update), so re-translation of whole files is never forced by the mechanism.\n"

The core frontier groups [architecture](../../../../docs/architecture.md), the [Cordis primer](../../../../docs/cordis-primer.md), [defensive patterns](../../../../docs/defensive-patterns.md), the [glossary](../../../../docs/glossary.md), and [testing](../../../../docs/testing.md) because their terminology, links, and contributor contracts inform one another; admitting only part would leave the enforced corpus internally inconsistent. A site-published pair uses `pairedPages()` so the root locale projects `.zh.md` and `/en/` projects `.md`; creating a counterpart alone does not publish it.\n- **Pairing records are metadata, not Cordis Loader configuration.** Cordis configuration discovery accepts actual `.cordis.yml` and `.cordis.yaml` files while excluding `*.i18n.yaml`, even when the document name contains `cordis`. This preserves validation of executable Loader entries without parsing translation hashes as configuration.\n- **Translation is agent work with human review.** The committed workflow is [.agents/skills/dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md), following the same pattern as [dsh-code-review](../../../skills/dsh-code-review/SKILL.md): the skill carries the workflow and defers to the docs as sources of truth. The skill directs the orchestrating agent to delegate translation writing to a subagent.\n\n## Verification\n\nThe verification contract covers each boundary independently. `verify-translation-pairing` pins pair completeness, hashes, switchers, and structure; [`project-doc-site.spec.ts`](../../../../scripts/project-doc-site.spec.ts) pins locale-specific source selection for published pairs; [`cordis-config-files.spec.ts`](../../../../scripts/cordis-config-files.spec.ts) pins discovery of Loader YAML and exclusion of translation records; and the [translation-prompt runnable snapshot](../../../../scripts/translation-prompt.snapshot.ts) pins the rendered system message, five reviewed example pairs, source request, and consumed response. Together these checks make pair drift, publication drift, configuration misclassification, and model-visible prompt drift review-visible.\n\n## Alternatives considered\n\n- **English as the canonical source with a fingerprint inside the translation** — the design first proposed for this Agent Note: `.zh.md` files carried an HTML comment recording the English source's blob hash, and translation flowed EN → ZH only.

The sidecar record covering BOTH sides replaced the in-file one-directional fingerprint; the blob-hash mechanics survived unchanged.\n- **Locale directories (`docs/en/` + `docs/zh/`, the Kubernetes/ECharts model)** — rejected: this repo has no docs-site framework to map locales to routes, moving every English file would churn every existing cross-reference, and `verify-md-links`/`verify-doc-refs` would need path-mapping logic instead of working unchanged.\n- **A separate translation repo (the PingCAP `docs`/`docs-cn` model)** — rejected: right for a docs product with independent release trains, overkill for a monorepo's own documentation; it also puts the translation outside the reach of this repo's gates.\n- **Interleaved bilingual files (single file, both languages)** — rejected: doubles every diff, breaks the one-line-per-paragraph convention's diff ergonomics, and makes partial inconsistency invisible.\n- **Commit-hash records (the MDN `l10n.sourceCommit` model)** — rejected in favor of blob hashes: a same-PR edit has no commit hash yet, so the MDN model cannot express \"consistent as of the state this PR introduces\", and verifying it requires git history instead of file content.\n- **Comparing git timestamps of the pair (no record)** — rejected: formatting-only edits would false-positive, and a counterpart committed after an unrelated edit would false-negative; content identity is the only signal that means what the gate claims.\n\n## Industry precedent\n\nPaired sibling files with locale suffixes are the dominant Chinese big-tech convention (ant-design `index.zh-CN.md`/`index.en-US.md`; arco-design `README.zh-CN.md` with a top-of-file switcher; Apache ShardingSphere's 387 `.cn.md`/`.en.md` pairs) — but none of those repos *enforce* pairing or consistency in CI; the convention holds by review alone. Consistency automation exists outside China: MDN's `l10n.sourceCommit` front-matter fingerprint, Vue's Ryu-Cho action (upstream-commit watcher that opens issues/PRs for stale translations), Kubernetes' localization drift scripts, and Microsoft's Azure co-op-translator (source-hash-driven LLM re-translation in CI). This design combines the two: the Chinese-ecosystem file layout with a hash-pair gate, plus a committed agent skill in place of a bot service.\n\n## Consequences\n\n- Editing either side of a paired document obligates the same PR to update the counterpart and re-record the pair — the gate makes the doc-sync rule bilingual, and CI (not reviewer memory) carries the invariant.\n- Every pair adds a third file to the tree. The record is machine-written (`--write`), so the cost is directory noise, not maintenance effort; in exchange, \"who confirmed these consistent, and when\" is answerable from git blame on the yaml.\n- When the two sides disagree, no mechanical rule picks a winner — the PR review does. That is the price of equal authority, accepted deliberately: the alternative (a canonical language) forbids Chinese-first authoring.\n- Generated docs (`cordis-catalog/`, `tool-catalog/`, `module-graph.md`) are excluded for now; the planned follow-up is to teach their generators to emit Chinese alongside English, at which point they leave the exclusion list.\n- Rollout is incremental by design: documents outside `required` are visible backlog (`--list`), not red CI, so pairs land in reviewable batches without a big-bang PR. A date-named document dated on or after the manifest's `requiredSince` cutoff merges bilingual or not at all, so new date-named Agent Notes do not enlarge that backlog.\n- The recorded hashes double as the update tool (`git cat-file -p <hash>` recovers either side's last-confirmed text for a minimal diff-based update), so re-translation of whole files is never forced by the mechanism.\n"
