# Agent Note: Doc-sync enforcement
Status: implemented
English | [中文](2026-06-11-doc-sync-enforcement.zh.md)
## 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.
## Decision
Two gates, mirroring the existing `scripts/` style (tsx ESM, one job each):
1. **`doc-typecheck`** extracts every fenced ` ```ts ` block from `README.md`, `docs/**`, and `packages/*/README.md`, writes them to a temp project extending the root `tsconfig.json`, and compiles it with `tsc -b`. The temp project reuses the source `paths` map and the root project references, so documentation examples see source while vendored code remains checked under its own tsconfig settings. A block that is a deliberate sketch opts out with an explicit ` ```ts ignore-check ` info string; the script reports the opt-out ratio and fails if it exceeds half, so the escape hatch can't quietly become the norm.
2. **`verify-event-taxonomy`** extracts the event names from the `interface Events` blocks across `packages/*/src` and from the taxonomy table in `docs/architecture.md`, and asserts the two sets match exactly. Verify, don't generate: the table keeps its hand-written Mode/Purpose columns; only the set of names is checked. (Landing this surfaced three events the table had been missing — `tools/change`, `llm/adapter-change`, `system-prompt/change`.) **Superseded** by [the generated cordis catalog](2026-06-20-generated-cordis-catalog.md): this gate and its `architecture.md` table are retired in favor of the fully-generated `docs/cordis-catalog/events.md` + `docs/cordis-catalog/services.md` and their `verify-cordis-catalog` freshness gate. The other gates here (`doc-typecheck`, and the `verify-md-wrap` amendment below) are unaffected.
Both run via a shared `doc-sync` package.json script that contributors invoke for relevant documentation changes and CI invokes exhaustively. The [fast local Git hooks](2026-07-22-fast-local-git-hooks.md) decision keeps this surface-selected work out of commit and push hooks.
**Amendment (2026-06-17):** a third gate, **`verify-md-wrap`**, was later folded into `doc-sync`. It parses each in-scope Markdown file (`README.md`, `docs/**`, `packages/*/README.md`, plus `AGENTS.md` / `packages/AGENTS.md`) with `mdast-util-from-markdown` + GFM and fails on any `paragraph` node spanning more than one source line, enforcing the docs/AGENTS.md "one physical line per paragraph" writing rule. Same verify-don't-generate principle: it reports hard-wraps and never rewrites, so it adds no formatting churn. `doc-sync` is now three gates.
## Alternatives considered
- **API-extractor golden reports** ([the deferred proposal](../../proposed/process/2026-06-11-api-extractor-reports.md)) — deliberately deferred: low value for an internal monorepo where reviewers already see the source diff, and a heavy, finicky dependency.
- **Generating the taxonomy table from source** instead of verifying names — rejected as more machinery than the problem warranted; the table kept its hand-written Mode/Purpose columns until [the generated cordis catalog](2026-06-20-generated-cordis-catalog.md) superseded the check entirely.
## Consequences
- Doc drift in the checkable classes fails `doc-sync` and CI instead of waiting for a reviewer to notice. This is an instance of the "mechanical gates over prose" principle.
- Making doc snippets compile costs a few stub imports/`declare`s; the `ignore-check` ratio must stay low or the gate is theater (the ratio guard enforces this).
- The taxonomy check is name-only — a wrong Mode or Purpose column still needs human review.
- API reports remain available to revisit if the packages are ever published externally.

# 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/**``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 Noteagent 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。

A single fat-fingered path would have shipped a broken link with nothing to catch it.

# Agent Note: Documentation graph index for maintainers and SDK users
Status: implemented
English | [中文](2026-07-03-documentation-graph-atlas.zh.md)
## Problem
The repo already had several high-trust documentation surfaces, each on a different axis: [module-graph.md](../../../../docs/module-graph.md) is generated from package `peerDependencies`, the generated [Cordis events](../../../../docs/cordis-catalog/events.md) and [services](../../../../docs/cordis-catalog/services.md) catalogs are generated from Cordis `Events` and `Context` declarations, [tool-catalog.md](../../../../docs/tool-catalog.md) is generated by booting shipped tool plugins, and [core-data-structures/](../../../../docs/core-data-structures/core.md) uses `ts type-equiv` blocks to keep pasted type definitions synchronized with source.
Those references are accurate, but they are mostly catalogs. A maintainer still has to synthesize the relationships: which packages form a capability seam, which app bundles a concrete spine, which event is durable vs live, where a hook or policy plugin can intercept work, and which model-facing tool depends on which service. An SDK user has the same problem from another angle: "Which package do I install or load for the behavior I want, and which event/service/tool do I extend?"
The hooks subsystem makes event producer/consumer topology and interception points much more important, and the filesystem seam makes capability seams, policy vetoes, tool presentation, and SDK assembly paths much more important — relationship graphs scoped to a small bash/todo/subagent surface would have gone stale immediately.
## Decision
Add generated relationship graph docs, indexed at [docs/graph-atlas.md](../../../../docs/graph-atlas.md), produced by focused generators and verified by `pnpm run verify-doc-graphs` / existing catalog freshness checks as part of `doc-sync`.
The index is a relationship layer above the existing catalogs. It does not replace exact references; instead, it links to them and explains how their pieces fit together.
### Maintenance modes
Every graph page declares one maintenance mode:
- **Generated**: all nodes and edges are discovered from source; `--check` fails if the committed artifact is stale.
- **Hybrid generated**: source discovers the inventory, a small manifest classifies irreducible policy, and a completeness guard fails if discovered items are unclassified.
- **Curated**: the diagram explains design intent, temporal order, or ownership; it is emitted by the generator so the graph docs remain a regenerated unit, but the content is deliberately authored.
### First shipped index
The index links ten relationship surfaces. Package topology and tool-package affordances live in the existing generated catalogs that already own those facts; the remaining focused diagrams are generated by `scripts/gen-doc-graphs.ts`.
| Graph | Maintenance mode | Source of truth |
|---|---|---|
| [module dependency graph](../../../../docs/module-graph.md) | generated | `packages/*/*/package.json` peer dependencies plus package group paths |
| [tool schema catalog and package map](../../../../docs/tool-catalog.md) | generated | boot-harvested tool schemas plus tool-package service/effect metadata |
| [capability seams and core services](../../../../docs/capability-seams.md) | hybrid generated | Cordis service declarations plus a role manifest in `gen-doc-graphs.ts` |
| [tui-agent app composition](../../../../examples/tui-agent/composition.md) | hybrid generated | `examples/tui-agent/cordis.yml` plugin list plus curated app/bundle expansion |
| [headless-agent app composition](../../../../examples/headless-agent/composition.md) | hybrid generated | `examples/headless-agent/cordis.yml` plugin list plus curated app/bundle expansion |
| [cordis-agent app composition](../../../../examples/cordis-agent/composition.md) | hybrid generated | `examples/cordis-agent/cordis.yml` plugin list plus curated app/bundle expansion |

### Why generators own the docs
Package topology stays in `gen-module-graph.ts`, and tool-package affordances stay in `gen-tool-catalog.ts`, because those generators already own the canonical facts and freshness gates. `gen-doc-graphs.ts` owns the remaining relationship pages and the index. The tradeoff is that curated diagrams are edited in TypeScript string blocks rather than directly in Markdown. That is acceptable for this first cut because the user-facing artifact is still plain Markdown/Mermaid, and a future change can split the curated pages out if authorship ergonomics matter more than regeneration.
### Completeness guards
The hybrid pages must fail loud when their manifests are stale:
- The module graph reads every package's `peerDependencies` and groups each package by its `packages/<group>/<pkg>` path.
- The tool catalog boot-harvests shipped tools and renders the package/service/effect map from the same manifest that its completeness guard already checks.
- The capability seam graph imports the Cordis service collector and asserts every discovered harness `ctx.<key>` is classified in `SERVICE_ROLES`, and every classified key still exists.
- The event producer/consumer matrix labels itself hybrid because subagent lifecycle events deliberately use `ctx.events.dispatch` for per-listener containment; those dynamic edges are explicit overrides rather than invisible omissions.
- `verify-mermaid` parses every repo-authored ` ```mermaid ` fence with Mermaid's own parser, so syntax errors fail `doc-sync` locally and in CI instead of showing up as broken GitHub-rendered diagrams.
## Alternatives considered
Committed diagrams use Mermaid because GitHub renders it in Markdown and it adds no new docs build dependency; dense many-to-many data such as event producer/consumer relationships uses Markdown tables instead. **PlantUML, hosted diagram services, and generated SVGs** were considered and deliberately not adopted until Mermaid becomes the limiting factor.
## Consequences
- Maintainers get visual entry points for topology, seams, event flow, lifecycle, and app composition.
- SDK users get a path from use case to package composition instead of only bottom-up package references.
- `doc-sync` now includes `verify-doc-graphs` and `verify-mermaid`, so graph drift and Mermaid syntax errors are caught with the other doc freshness gates.
- Future fs and hooks work has a concrete place to land new complexity: fs should expand the capability docs and tool catalog, while hooks should expand the event matrix and tool execution pipeline.

# 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`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``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``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: doc-sync through the gate scheduler
Status: implemented
English | [中文](2026-07-21-doc-sync-through-gate-scheduler.zh.md)
## Problem
`pnpm run doc-sync` was a `&&` chain of 24 `pnpm run` subcommands. Each link paid a full pnpm wrapper start (workspace resolution, script lookup, tsx boot) before its script ran; measured on a development host, the 24 script bodies together finish in about 34 seconds while the chained form takes around 3 minutes, and the wrapper stall reproduces on local disk, so every developer and CI lane pays it, not just network-filesystem checkouts. The chain also ran serially even though the member gates are read-only and independent, and it silently drifted from [scripts/run-gates.ts](../../../../scripts/run-gates.ts): `verify-cordis-api` joined the chain when the runtime API catalog landed but was never added to `docSyncLeafGates`, so CI never enforced that catalog's freshness.
## Decision
`doc-sync` in `package.json` delegates to the existing bounded scheduler — `tsx scripts/run-gates.ts doc-sync` — like the `check:ci:*` scripts ([parallel gate scheduling](2026-07-06-parallel-pre-push-gates.md), [current CI topology](2026-07-22-evidence-based-larger-hosted-runners.md)). The `doc-sync` mode expands to exactly `docSyncLeafGates()`, making the leaf list in `run-gates.ts` the single source of truth for the member set. The local mode caps default concurrency at four workers because several doc gates each build a full `ts.Program`; `DSH_GATE_CONCURRENCY` still overrides.
`docSyncLeafGates` includes `verify-cordis-api`, so relevant local documentation checks and CI gate the generated runtime API catalog alongside the other generated docs.
## Alternatives considered
- **Keep the `&&` chain and only fix the missing leaf** — repairs today's drift but keeps two member lists that will drift again, and keeps the 24 serial pnpm wrapper starts.
- **A dedicated `scripts/doc-sync.ts` importing each verify module in one process** — saves even the per-gate tsx boot, but requires refactoring all 24 scripts from run-at-import to callable entry points and loses the scheduler's per-gate timing, isolation, and failure grouping; the wrapper start the scheduler already avoids is the dominant cost.
- **Shell loop over `tsx scripts/*.ts`** — avoids pnpm wrapper starts cheaply but adds a second execution vocabulary next to the scheduler CI already uses, with none of its scheduling or reporting.
## Consequences
One `pnpm run doc-sync` now costs one pnpm wrapper start plus the slowest dependency chain of member gates instead of 24 wrapper starts plus the sum of all members. Adding a doc gate is one edit in `docSyncLeafGates` (plus the package script itself for ad hoc runs); `package.json` keeps the per-gate `verify-*` scripts as the vocabulary for running one gate by hand. The scheduler prints per-gate timing, so a slow doc-sync points at the gate that dominates. `pnpm run doc-sync` output is now interleaved scheduler output rather than sequential per-command output; anything parsing that output must key on the `run-gates:` summary lines.

# Agent Note: doc-sync 走门禁调度器
Status: implemented
[English](2026-07-21-doc-sync-through-gate-scheduler.md) | 中文
## 问题
`pnpm run doc-sync` 原本是把 24 个 `pnpm run` 子命令用 `&&` 串起来的链。每一环都要先付一次完整的 pnpm 包装层启动workspace 解析、脚本查找、tsx 启动才轮到脚本本体在开发机上实测24 个脚本本体合计约 34 秒即可跑完,而链式形态耗时约 3 分钟,且包装层的停顿在本地磁盘上同样复现,因此每位开发者和每条 CI 车道都在付这笔开销,并非只有网络文件系统上的检出受影响。这条链还是串行执行的,尽管各成员门禁只读且相互独立;它也在悄悄偏离 [scripts/run-gates.ts](../../../../scripts/run-gates.ts):运行时 API 目录落地时 `verify-cordis-api` 加入了链,却从未加进 `docSyncLeafGates`,导致 CI 从未把关该目录的新鲜度。
## 决策
`package.json` 中的 `doc-sync` 委托给既有的有界调度器——`tsx scripts/run-gates.ts doc-sync`——与各 `check:ci:*` 脚本的做法一致([并行门禁调度](2026-07-06-parallel-pre-push-gates.md)、[当前 CI 拓扑](2026-07-22-evidence-based-larger-hosted-runners.md))。`doc-sync` 模式恰好展开为 `docSyncLeafGates()`,使 `run-gates.ts` 里的叶子列表成为成员集合的唯一真源。本地模式把默认并发上限设为四个 worker因为多个文档门禁各自要构建完整的 `ts.Program``DSH_GATE_CONCURRENCY` 仍可覆盖。
`docSyncLeafGates` 包含 `verify-cordis-api`,因此相关的本地文档检查与 CI 会同其他生成文档一起把关生成的运行时 API 目录。
## 考虑过的替代方案
- **保留 `&&` 链,只补缺失的叶子**——能修好今天的漂移,但保留了两份还会再漂移的成员列表,也保留了 24 次串行的 pnpm 包装层启动。
- **专门的 `scripts/doc-sync.ts` 在单进程内 import 各校验模块**——连每个门禁的 tsx 启动也能省掉,但需要把全部 24 个脚本从 import 即执行改造成可调用入口,还会失去调度器的按门禁计时、隔离和失败分组;而调度器已经避免的包装层启动才是开销的大头。
- **用 shell 循环跑 `tsx scripts/*.ts`**——以低成本避开 pnpm 包装层启动,却在 CI 已经使用的调度器旁边增加了第二套执行词汇,且没有它的任何调度与报告能力。
## 结果
一次 `pnpm run doc-sync` 的成本从 24 次包装层启动加全部成员之和,变为一次包装层启动加成员门禁中最慢的依赖链。新增文档门禁只需在 `docSyncLeafGates` 改一处(外加 package script 本身以便手工单独运行);`package.json` 保留各 `verify-*` 脚本作为手工运行单个门禁的词汇。调度器输出按门禁计时doc-sync 变慢时能直接指向占大头的门禁。`pnpm run doc-sync` 的输出从逐命令顺序输出变为调度器的交错输出;解析该输出的工具必须以 `run-gates:` 摘要行为准。

# Agent Note: installer skips the clone when run from inside a checkout
Status: implemented
English | [中文](2026-07-22-installer-in-repo-skip-clone.zh.md)
## Problem
`scripts/install.sh` is written for the `curl ... | sh` path: it clones the harness into `~/.dsh/source`, then installs, links, and launches. Contributors who already have a checkout and run the same script directly (`sh scripts/install.sh`) got a second, unrelated clone at `~/.dsh/source` — installing and linking a different tree than the one they were working in, with no way to exercise the local script against the local source.
## Decision
The script detects when it is executing from inside a real checkout and, in that mode, reuses that checkout and skips the clone/update step entirely, leaving the working tree untouched.
Detection keys on `$0`: under `curl ... | sh` the script text arrives on stdin, so `$0` is the shell name and no file path resolves; running a checked-out copy makes `$0` the script file. When `$0` is a readable file whose parent is a `scripts/` directory inside a tree that carries both the `bin/dsh` launcher and `scripts/install.sh`, the script sets `IN_REPO=1` and repoints `DSH_SOURCE` at that repo root. Step 2 then prints a "using existing checkout" line and does nothing else — no `git fetch`, no `git checkout -B`, so the user's working tree and branch are never mutated. `DSH_REF` is advisory and ignored in this mode.
Explicit `DSH_SOURCE` wins over detection: the value is captured before defaulting, and in-repo detection only repoints an unset `DSH_SOURCE` (or one already equal to the detected repo root). Setting `DSH_SOURCE` to a different directory opts back into the normal clone/update path, so the escape hatch to install a separate tree from within a checkout still exists.
## Alternatives considered
**Detect via `git rev-parse --show-toplevel` on the current directory.** Rejected: `curl ... | sh` frequently runs from inside some unrelated git repo (the user's `cwd`), which would false-positive and skip the clone against a tree that is not dsh. Anchoring on `$0`'s own location ties the decision to where the script physically lives, and the `bin/dsh` + `scripts/install.sh` markers confirm it is actually a dsh checkout.
**Always skip the clone whenever run from a file, ignoring `DSH_SOURCE`.** Rejected: a contributor may legitimately run the in-repo script to provision a separate `~/.dsh/source` install; honoring an explicit `DSH_SOURCE` that differs from the checkout preserves that path.
## Consequences
Running `sh scripts/install.sh` from a checkout now installs, links, and launches that checkout instead of cloning a parallel one, which also makes the local script testable against local source. The cost is a detection block that couples to the repo layout (`scripts/` beside `bin/dsh`); if the launcher or script ever moves, the markers must move with it. The behavior is documented in the script header and both README files, and verified by running the four paths (in-repo skip, curl-style clone, explicit `DSH_SOURCE` elsewhere opting back in, explicit `DSH_SOURCE` equal to repo root still skipping).

# Agent Note: 在检出目录内运行时安装脚本跳过克隆
Status: implemented
[English](2026-07-22-installer-in-repo-skip-clone.md) | 中文
## 问题
`scripts/install.sh`是为`curl ... | sh`路径编写的:它把 harness 克隆到`~/.dsh/source`,然后安装、软链接并启动。已经有检出的贡献者若直接运行同一脚本(`sh scripts/install.sh`),会在`~/.dsh/source`得到第二份无关的克隆——安装并软链接的是与他们正在工作的树不同的另一棵树,且无从用本地脚本验证本地源码。
## 决策
脚本会检测自身是否在真实检出内执行;在该模式下,它复用该检出并完全跳过克隆/更新步骤,保持工作树不受影响。
检测依据是`$0`:在`curl ... | sh`下脚本文本经由 stdin 到达,因此`$0`是 shell 名称、无路径可解析;运行已检出的副本会使`$0`成为脚本文件本身。当`$0`是一个可读文件、其父目录是一个`scripts/`目录、且该树同时带有`bin/dsh`启动器和`scripts/install.sh`时,脚本会设置`IN_REPO=1`并把`DSH_SOURCE`重新指向该仓库根。步骤 2 随后打印一行"using existing checkout"并不做其他事——不执行`git fetch`、不执行`git checkout -B`,因此用户的工作树和分支绝不会被改动。`DSH_REF`在该模式下仅供参考、被忽略。
显式的`DSH_SOURCE`优先于检测:该值在默认化之前就被捕获,检测只会重新指向未设置的`DSH_SOURCE`(或已经等于检测到的仓库根的那个)。把`DSH_SOURCE`设为其他目录会重新回到正常的克隆/更新路径,因此在检出目录内安装另一棵独立树的退路依然存在。
## 备选方案
**通过对当前目录执行`git rev-parse --show-toplevel`来检测。** 已否决:`curl ... | sh`常常在某个无关的 git 仓库(用户的`cwd`)内运行,这会误判并对一棵并非 dsh 的树跳过克隆。把决策锚定在`$0`自身的位置,使其绑定到脚本实际所在之处,而`bin/dsh` + `scripts/install.sh`标记则确认它确实是一个 dsh 检出。
**只要从文件运行就总是跳过克隆,忽略`DSH_SOURCE`。** 已否决:贡献者可能合理地运行检出内脚本来配置一份独立的`~/.dsh/source`安装;尊重与检出不同的显式`DSH_SOURCE`保留了该路径。
## 影响
现在从检出目录运行`sh scripts/install.sh`会安装、软链接并启动该检出,而不是克隆一份平行副本,这也让本地脚本可以针对本地源码进行测试。代价是一段与仓库布局耦合的检测逻辑(`scripts/``bin/dsh`并列);若启动器或脚本将来移动,标记必须随之移动。该行为记录在脚本头部和两份 README 中并通过运行四条路径来验证检出内跳过、curl 式克隆、显式`DSH_SOURCE`指向他处而回到克隆、显式`DSH_SOURCE`等于仓库根仍跳过)。

# Agent Note: Browser demo GIF recording
Status: implemented
English | [中文](2026-07-23-browser-demo-gif-recording.zh.md)
## Problem
Browser demonstrations have been assembled with one-off capture and encoding commands. That makes timing and output size inconsistent, encourages continuous recordings that obscure the useful state changes, and can blur the boundary between a genuine server or API flow and a fixture. Combining local recording with attachment upload or pull-request editing also gives a media task unrelated remote-write authority.
## Decision
The repository provides the [`record-browser-gif`](../../../skills/record-browser-gif/SKILL.md) skill for local browser-demo artifacts. It uses the available browser-control workflow, establishes whether the requested flow is real, fixture-backed, or otherwise simulated, and captures a small storyboard only after semantically observable UI states. Frames and the output live outside the Git worktree by default.
The bundled `encode_gif.py` helper orders frames lexically, assigns explicit hold durations, uses an `ffmpeg` palette pipeline, and validates source dimensions plus the encoded frame count, dimensions, duration, and byte limit through `ffprobe`. The workflow stops after returning the verified absolute GIF path; uploading the artifact and mutating a pull request, issue, or document remain separate workflows.
## Alternatives considered
**Record continuous video and convert it afterward.** Continuous capture preserves every cursor movement and loading transition but produces larger, noisier artifacts and makes deterministic timing harder. A state storyboard better fits short feature demonstrations where the meaningful evidence is a handful of visible transitions.
**Keep an inline `ffmpeg` recipe in the skill.** Reconstructing quoting, timing manifests, palette filters, overwrite behavior, and post-encode checks in every run is error-prone. A bundled helper keeps those mechanics executable while the skill owns capture judgment.
**Include GitHub attachment and description editing.** Upload and remote mutation require separate authentication, confirmation, and recovery rules. Excluding them keeps invocation of a recording skill local and reversible.
**Use a fixture whenever it is easier to stage.** Fixtures are valid when the requested demonstration is explicitly fixture-backed, but they do not substantiate a real-server or real-API claim. The skill preserves the requested provenance and reports a missing prerequisite instead of silently changing it.
## Consequences
Recordings are small, repeatable local artifacts with explicit provenance and a clean repository boundary. The workflow gives up smooth continuous motion, depends on locally available `ffmpeg` and `ffprobe`, and requires the recorder to identify semantic capture points. The helper is exercised against a four-state browser demonstration and invalid duration input; skill shape and repository links are covered by the skill validator and documentation gates.

# Agent Note: 浏览器演示 GIF 录制
Status: implemented
[English](2026-07-23-browser-demo-gif-recording.md) | 中文
## 问题
浏览器演示一直通过一次性的截取与编码命令制作。这会导致播放节奏和输出大小不一致,容易让录制者选择连续录制,反而掩盖有用的状态变化,还可能模糊真实服务器或 API 流程与 fixture测试前置数据之间的界限。将本地录制与附件上传或 PRPull Request编辑合并在同一任务中还会让本应仅处理媒体的任务获得无关的远程写入权限。
## 决策
仓库提供 [`record-browser-gif`](../../../skills/record-browser-gif/SKILL.md) skill技能用于生成本地浏览器演示产物。该 skill 使用当前可用的浏览器控制工作流,先确认请求的流程是真实流程、由 fixture 支撑,还是采用其他模拟方式,再仅在 UI 达到语义上可观察的状态后截取一组精简的分镜帧。帧文件与输出产物默认存放在 Git worktree 之外。
随附的 `encode_gif.py` 辅助脚本按词法顺序排列各帧,为每帧设置明确的停留时长,通过 `ffmpeg` 调色板流水线编码,并借助 `ffprobe` 校验源图像尺寸以及编码结果的帧数、尺寸、时长和字节上限。工作流在返回已验证的 GIF 绝对路径后即结束;上传产物以及修改 PR、issue 或文档仍属于独立的工作流。
## 曾考虑的替代方案
**连续录制视频后再转换。**连续录制能保留每一次光标移动和加载过渡,但会产生体积更大、干扰更多的产物,也更难保持确定的播放时序。状态分镜更适合简短的功能演示,因为有意义的证据只是少数几个可见的状态变化。
**在 skill 中保留内联 `ffmpeg` 配方。**每次运行都重新组装引号转义、时序清单、调色板过滤器、覆盖行为和编码后检查容易出错。随附的辅助脚本使这些机制保持可执行skill 则负责判断何时截取画面。
**纳入 GitHub 附件上传与描述编辑。**上传和远程修改需要各自独立的身份认证、确认与恢复规则。将它们排除在外,可以使录制 skill 的调用保持本地且可撤销。
**每当 fixture 更容易布置时就使用它。**当请求明确要求由 fixture 支撑演示时,使用 fixture 是有效的;但它无法为真实服务器或真实 API 的声明提供证据。该 skill 会保持请求指定的演示来源,并在缺少先决条件时报告问题,不会擅自更改来源。
## 后果
录制结果成为体积小、可重复生成的本地产物,明确标注演示来源,并与仓库保持清晰边界。该工作流放弃了流畅的连续动态效果,依赖本机提供的 `ffmpeg``ffprobe`并要求录制者识别具有语义意义的截取时点。测试使用四状态浏览器演示与无效时长输入检验辅助脚本skill 的结构及仓库链接由 skill 校验器和文档门禁覆盖。

# Agent Note: Prefer maintained dependencies over hand-rolling
Status: implemented
English | [中文](2026-07-26-dependencies-over-hand-rolling.zh.md)
## Problem
The harness hand-rolls a lot of infrastructure that mature external packages already provide. Some of that is deliberate — vendored Cordis ([vendoring decision](2026-06-11-vendor-cordis-as-source.md)), the [twin LLM adapters](../architecture/2026-06-13-twin-llm-adapters.md), schemastery as the config-schema standard — but much of it accreted from an unstated "avoid new dependencies" reflex: the repo-wide external dependency list stayed tiny while packages grew their own SSE parsers, protocol framers, retry loops, and glob matchers. Nothing in `AGENTS.md` actually stated a dependency policy, so agents inferred one from the existing pattern, and the inferred rule ("don't add deps") is stricter than anyone decided. That is the "Not Invented Here" fallacy operating by default: every hand-rolled clone of a well-maintained library is code we test, document, review, and debug ourselves, with none of the ecosystem's accumulated edge-case fixes.
## Decision
Introducing an external dependency is a legitimate simplification, not a policy exception. When a well-maintained package (or a Node builtin at our engine floor) covers a hand-rolled surface, replacing the hand-rolled code is the preferred direction, subject to the same evidence standard as any other simplification: the swap must genuinely shrink what we own — code, tests, and contract surface — rather than merely relocate complexity behind a wrapper.
The bar for a new dependency:
- **Net deletion.** The dependency replaces real owned code (implementation + dedicated tests + docs), not hypothetical future code. A dep that only adds capability is a feature decision, not a simplification.
- **Health.** Actively maintained, widely used, sensible transitive footprint. A tiny unmaintained package trades our code for someone's abandoned code.
- **Fit at the boundary.** The package's semantics cover our actual contract; residual semantics we still hand-roll around it count against the swap.
- **Not a settled seam.** schemastery (config schemas), vendored Cordis, the `@earendil-works` twins, and other decisions recorded in implemented Agent Notes are not reopened by this policy; a swap that collapses a recorded design needs to beat the recorded rationale, not just cite this note.
`packages/util/`'s "zero-dependency" charter describes that group's *export* discipline — util packages stay free of harness dependencies so any group can depend on them — and does not ban external packages where they simplify; a util package whose entire job a maintained external package does better should be replaced by the dependency, not preserved for the charter.
Dependency-swap proposals are recorded as `proposed/simplification` Agent Notes like any other removal, with the candidate package, the deletable surface, residual semantics, and supply-chain considerations stated. The [supply-chain proposal](../../proposed/process/2026-06-11-supply-chain-and-vendor-drift.md) owns advisory scanning and update cadence for the dependency list this policy grows.
## Alternatives considered
- **Keep the implicit no-new-deps culture.** Rejected: it was never a recorded decision, and its cost is concrete — hand-rolled protocol and parsing code duplicates battle-tested libraries, inflates the per-file coverage burden, and slows every reviewer who must re-derive edge cases the ecosystem already fixed.
- **A hard allowlist of approved packages.** Rejected: the repo is pre-release and the dependency set is small; a per-PR evidence bar (net deletion, health, fit) plus review keeps judgment where the context is, without a standing committee artifact that would itself need maintenance.
- **Vendor every new dependency like Cordis.** Rejected: vendoring is for packages we must patch or pin against upstream churn ([vendoring decision](2026-06-11-vendor-cordis-as-source.md)); applying it broadly recreates the maintenance burden the dependency was meant to shed. Ordinary npm dependencies with lockfile pinning are the default.
## Consequences
- Agents and contributors surveying for simplifications now treat "replace hand-rolled X with package Y" as in-scope output; [dsh-find-simplifications](../../../skills/dsh-find-simplifications/SKILL.md) carries the corresponding guidance.
- The dependency list will grow, and with it the supply-chain surface; the mitigations live in the [supply-chain proposal](../../proposed/process/2026-06-11-supply-chain-and-vendor-drift.md), which this policy makes more urgent.
- Root `AGENTS.md` carries the one-line rule; this note owns the rationale and the bar.

# Agent Note: 优先选用持续维护的依赖,而非手写实现
Status: implemented
[English](2026-07-26-dependencies-over-hand-rolling.md) | 中文
## 问题
harness 手写了大量基础设施而成熟的外部包package早已提供同等能力。其中一部分是有意为之——以源码形式收录的 Cordis[引入 vendor 的决策](2026-06-11-vendor-cordis-as-source.md))、[孪生 LLM大语言模型适配器](../architecture/2026-06-13-twin-llm-adapters.md)、作为配置 schema 标准的 schemastery——但相当大一部分源自一条未经言明的「避免新依赖」反射逐渐累积而成仓库级的外部依赖清单始终很小各包却各自长出了自己的 SSEServer-Sent Events解析器、协议分帧器、重试循环和 glob 匹配器。`AGENTS.md` 其实从未写下任何依赖政策agent智能体只能从既有模式中自行推断出一条而这条推断出的规则「不要加依赖」比任何人实际决定过的都更严格。这正是 Not Invented Here非我发明谬误在默认状态下运作每一个对维护良好的库的手写克隆都是要由我们自己测试、撰写文档、评审和调试的代码却享受不到生态累积下来的边界情况修复。
## 决策
引入外部依赖是一种正当的简化,而不是政策特例。当一个维护良好的包(或我们引擎下限即已提供的 Node 内置能力)覆盖了某块手写接口面时,替换手写代码就是优先方向,并遵循与其他任何简化相同的证据标准:这次替换必须切实缩减我们持有的东西(代码、测试和契约面),而不是仅仅把复杂度挪到一个包装层后面。
新依赖的准入门槛:
- **净删除。** 该依赖替换的是真实持有的代码(实现 + 专属测试 + 文档),而不是假想中的未来代码。只增加能力的依赖属于功能决策,不属于简化。
- **健康度。** 持续维护、广泛使用、传递依赖足迹合理。一个无人维护的小包,只是拿我们的代码换来别人废弃的代码。
- **边界契合。** 该包的语义要覆盖我们的实际契约;仍需围绕它手写补齐的残留语义,要计入这次替换的减分项。
- **不触碰已定案的 seam。** schemastery配置 schema、源码收录的 Cordis、`@earendil-works` 孪生适配器,以及其他记录在已实现 Agent Noteagent 决策记录)中的决策,不因本政策而重开;一次会瓦解已记录设计的替换,必须胜过所记录的论证理由,而不能只援引本 Agent Note。
`packages/util/` 的「零依赖」章程描述的是该分组的*导出*纪律util 包不携带 harness 依赖,从而任何分组都能依赖它们),并不禁止在能带来简化时使用外部包;如果一个 util 包的全部职责有维护良好的外部包做得更好,就应当用该依赖替换它,而不是为了章程而保留它。
依赖替换提案与其他任何移除类提案一样,记录为 `proposed/simplification` Agent Note写明候选包、可删除的接口面、残留语义和供应链考量。本政策会使依赖清单增长这份清单的安全公告扫描与更新节奏由[供应链提案](../../proposed/process/2026-06-11-supply-chain-and-vendor-drift.md)负责。
## 曾考虑的替代方案
- **维持隐性的「不加新依赖」文化。** 不予采纳:它从来不是一项有记录的决策,而其成本是具体的——手写的协议与解析代码重复实现了久经实战检验的库,推高了按文件计的覆盖率负担,还拖慢每一位评审人:他们必须重新推导生态早已修复的边界情况。
- **一份获批包的硬性白名单。** 不予采纳:仓库处于预发布阶段,依赖集合很小;按 PRPull Request设置证据门槛净删除、健康度、契合度再加评审就能把判断留在上下文所在之处无需一份本身也需要维护的常设委员会式产物。
- **像 Cordis 一样把每个新依赖都以源码形式收录。** 不予采纳源码收录vendor只适用于我们必须打补丁、或必须锁定以抵御上游变动的包[引入 vendor 的决策](2026-06-11-vendor-cordis-as-source.md));将其推广到所有依赖,会重新制造出引入依赖本要卸下的维护负担。默认做法是普通 NPM 依赖加 lockfile 锁定。
## 后果
- 巡查简化机会的 agent 与贡献者,现在把「用包 Y 替换手写的 X」视为范围内的产出[dsh-find-simplifications](../../../skills/dsh-find-simplifications/SKILL.md) 承载相应指引。
- 依赖清单会增长,供应链接触面随之扩大;缓解措施记录在[供应链提案](../../proposed/process/2026-06-11-supply-chain-and-vendor-drift.md)中,本政策使该提案更加紧迫。
-`AGENTS.md` 承载一行规则;论证理由与准入门槛由本 Agent Note 持有。

That cost is justified when the rationale can guide future work, but not for closed UI details, minor fixes, superseded implementation mechanics, or process history whose current authority lives elsewhere. Deleting every low-value implemented record would erase useful historical evidence, while retaining every rejected proposal preserves ideas that are neither plausible nor instructive. The corpus needs a retention boundary that distinguishes active guidance from frozen history without turning archival into another maintenance tier.
## Decision
Only implemented Agent Notes can be archived. An implemented note moves when its shipped decision is complete and its rationale, alternatives, consequences, negative guarantees, and reintroduction conditions are unlikely to guide future work. Foundational boundaries, durable and wire semantics, security rules, recurring design temptations, and unresolved reintroduction conditions remain active regardless of age or word count. Proposed notes never enter the archive; an obsolete proposal becomes rejected. A rejected note remains only while it prevents a tempting, meaningful mistake and is otherwise deleted as a complete triplet.
The archive uses `.agents/notes/archived/{kind}/yyyy-mm-dd-topic.md`; the redundant `implemented` segment is absent. The archival change moves the complete English, Chinese, and consistency-sidecar triplet, leaves `Status: implemented` intact, and inserts `Archived: YYYY-MM-DD` immediately below it in both language files. Relocation, that metadata line, the corresponding sidecar re-record, and mechanical inbound-link repair are the only permitted archival edits.
After archival, the triplet is permanently frozen and is historical context rather than current authority. It is not updated for renamed packages, changed behavior, translation standards, formatting rules, broken outbound links, or later documentation contracts. Active prose may intentionally link into an archived note, redirect that link to current authority, or delete it. Repository gates therefore validate links into archived files but never treat archived files as link sources.
[`verify-archived-agent-notes`](../../../../scripts/verify-archived-agent-notes.ts) owns the frozen boundary. It accepts only the closed set of Agent Note kinds, requires a complete triplet with implemented status and matching valid archive dates, verifies the sidecar against both current Git blob hashes, and seals every artifact by path and SHA-256 content hash in an append-only manifest. Its `--write` mode first proves every existing seal unchanged and then appends only newly archived artifacts. Pull-request CI supplies the trusted base SHA and checks out complete history before running the verifier, so a reused runner's shallow checkout cannot omit the baseline manifest. The ordinary Agent Note format, translation-pairing, wrapping, Markdown-link, package-path, Mermaid, documentation-TypeScript, and type-equivalence gates exclude archive sources; their evolving standards cannot create pressure to edit history.
The [`dsh-archive-agent-notes`](../../../skills/dsh-archive-agent-notes/SKILL.md) workflow owns classification. It requires a semantic note-by-note audit, uses code and current documentation to identify present authority, treats word count only as triage, carries calibrated keep/archive/delete examples, and reports genuinely borderline outcomes for review.
## Alternatives considered
**Delete every note that leaves the active corpus.** Rejected because an implemented record can have low forward guidance while still providing useful historical evidence about a closed decision. A content-sealed archive preserves that evidence without pretending it remains current.
**Keep every implemented and rejected note active.** Rejected because maintenance effort and search noise grow with records that no longer help a future decision. Rejected notes in particular earn retention only by preventing a plausible fallacy.
**Archive rejected or proposed notes too.** Rejected because archive status means “implemented historical decision.” An obsolete proposal needs an explicit rejection, while a rejection with no guardrail value needs deletion rather than a second low-value holding area.
**Continue applying all documentation gates to archived notes.** Rejected because a later formatting, translation, code, package, or link rule would require rewriting the historical snapshot. The dedicated verifier owns completeness and immutability instead.
**Permit factual refreshes while freezing only rationale.** Rejected because that recreates the judgment and translation burden of the active corpus and makes it unclear which clauses are historical. Current facts belong in active documentation or a new active Agent Note.
## Consequences
The active corpus becomes a set of decisions expected to influence future work, while low-value implemented history remains searchable and linkable without consuming maintenance attention. Rejected clutter can disappear when it no longer protects a meaningful choice, and proposed work cannot quietly evade a verdict through archival. The archive adds a manifest, a dedicated verifier, and an explicit one-time metadata step. Archived facts and outbound links can become stale by design, so readers and agents must treat active code and documentation as authority and cite an archived note only as history.

# Agent Note: 将未来指导价值较低的 Agent Note 冻结在活跃记录集合之外
Status: implemented
[English](2026-07-26-frozen-agent-note-archive.md) | 中文
## 问题
implemented Agent Noteagent 决策记录作为当前决策记录持续维护因此活跃记录集合中的每个路径、符号、默认值、译文、代码围栏、包package引用和出站链接都会形成维护义务。当决策依据可以指导未来工作时这项成本合理但对于已经收尾的 UI 细节、小型修复、已被取代的实现机制,或当前权威依据已转移到别处的流程历史,这项成本并不值得。删除所有低价值的已实施记录会抹去有用的历史证据,而保留每一项被否决的提案,又会留下既无采纳可能也无启发意义的想法。这套记录集合需要一道留存边界,在区分活跃指导与冻结历史的同时,避免让归档成为另一个维护层级。
## 决策
只有 implemented Agent Note 可以归档。当一份已实施记录的交付决策已经完整落地且其决策依据、备选方案、后果、否定性保证和重新引入条件不太可能再指导未来工作时将其移入归档。基础性边界、持久化语义与协议语义、安全规则、反复出现且看似诱人的设计选择和尚未解决的重新引入条件无论记录的存续时间或字数如何都继续作为活跃记录保留。proposed Agent Note 绝不进入归档;过时的提案应转为 rejected。仅当 rejected Agent Note 仍能避免一种诱人且影响重大的错误时保留,否则将其三个配对文件完整删除。
归档路径为 `.agents/notes/archived/{kind}/yyyy-mm-dd-topic.md`,其中省略了冗余的 `implemented` 层级。归档变更会移动完整的英文、中文和一致性伴随记录三个文件,保留 `Status: implemented`,并在两种语言的文件中紧接该状态行插入 `Archived: YYYY-MM-DD`。归档时只允许做文件迁移、添加该元数据行、相应地重新记录伴随文件,以及机械修复入站链接。
归档后,这三个文件永久冻结,只作为历史背景,不再是当前权威依据。不得因为包重命名、行为变化、翻译标准、格式规则、出站链接失效或后续文档契约而更新归档文件。活跃文档可以有意链接到归档 Agent Note也可以把该链接重定向到当前权威依据或直接删除。仓库门禁因此会校验指向归档文件的链接但绝不把归档文件作为链接源来校验。
[`verify-archived-agent-notes`](../../../../scripts/verify-archived-agent-notes.ts) 负责维护冻结边界。它只接受封闭集合中的 Agent Note 类别,要求三个配对文件完整、状态为 implemented且归档日期有效并互相匹配它还会用双方当前的 Git blob hash 校验伴随记录,并在仅追加的 manifest 中按路径和 SHA-256 内容 hash 封存每项产物。其 `--write` 模式会先证明每条现有封存记录对应的内容都未改变,再仅追加新归档的产物。拉取请求 CI 会提供可信的基准 SHA并在运行校验器前检出完整历史因此复用运行器上的浅克隆检出无法漏掉基线 manifest。普通的 Agent Note 格式、翻译配对、换行、Markdown 链接、包路径、Mermaid、文档 TypeScript 和类型等价门禁都排除归档源文件,因此这些门禁持续演进的标准不会产生修改历史记录的压力。
[`dsh-archive-agent-notes`](../../../skills/dsh-archive-agent-notes/SKILL.md) 工作流负责分类判断。它要求逐份 Agent Note 做语义审计,使用代码和当前文档识别现行权威依据,仅把字数作为初步筛选手段,收录经过校准的保留、归档和删除示例,并报告真正处于边界的结果,以供评审。
## 曾考虑的替代方案
**删除每一份移出活跃记录集合的记录。** 不予采纳,因为已实施记录可能对未来的指导价值较低,却仍能为已经收尾的决策提供有用的历史证据。按内容 hash 封存的归档既能保留这些证据,又不会假装它们仍然反映当前状态。
**继续将每一份 implemented 和 rejected Agent Note 作为活跃记录保留。** 不予采纳,因为不再帮助未来决策的记录会不断增加维护成本和搜索噪声。尤其是 rejected Agent Note只有能避免一种可能发生的谬误时才值得保留。
**同时归档 rejected 或 proposed Agent Note。** 不予采纳,因为归档状态表达的是「已经实施的历史决策」。过时的提案需要明确转为 rejected无法提供防错价值的 rejected Agent Note 则应删除,而不是再放入第二个低价值存放区。
**继续对归档 Agent Note 应用所有文档门禁。** 不予采纳,因为后续新增的格式、翻译、代码、包或链接规则会迫使维护者重写历史快照。改由专用校验器负责完整性与不可变性。
**允许更新事实,只冻结决策依据。** 不予采纳,因为这会重新引入活跃记录集合的判断和翻译负担,也会让读者无法分辨哪些条款属于历史。当前事实应写在活跃文档或新的活跃 Agent Note 中。
## 后果
活跃记录集合由预计仍会影响未来工作的决策组成;未来指导价值较低的实施历史仍可搜索和链接,却不再消耗维护精力。当被否决的记录不再保护有意义的选择时,可以清除这类杂项;提案也无法通过归档悄悄逃避明确结论。归档机制增加一份 manifest、一个专用校验器和一个显式的一次性元数据步骤。归档中的事实和出站链接可以按设计逐渐陈旧因此读者和 agent 必须以活跃代码与文档为权威依据,并且仅将归档 Agent Note 作为历史引用。

# Agent Note: GUI pull request GIF evidence and assets-branch publication
Status: implemented
English | [中文](2026-07-26-gui-pr-gif-evidence-and-assets-branch.zh.md)
## Problem
A pull request that changes what a product user sees in the GUI is otherwise reviewed through prose and test names, neither of which shows the rendered result. The [browser-demo GIF recording](../../../skills/record-browser-gif/SKILL.md) skill produces truthful local GIFs but deliberately stopped at the local artifact, so each pull request that wanted to show one re-derived publication on its own — and committing the GIF to the pull request branch is never acceptable, because binary media in history bloats every future clone permanently.
The recording procedure itself also kept being re-learned failure by failure: screenshots written outside the browser tool's allowed roots or into missing directories fail at capture time, transient UI states polled across separate tool calls are lost because the turn settles between calls, substring completion predicates match the echo of the user's own prompt, and an inline environment-variable assignment on the encoder command expands too late to take effect.
## Decision
Every pull request that changes product-user-visible GUI behavior includes a demonstration GIF recorded with the [record-browser-gif skill](../../../skills/record-browser-gif/SKILL.md), with real provenance — a real server booted from that pull request's own branch tree, a real API key, and real model rounds — stated next to the embed. Fixture provenance is acceptable only when the user explicitly asked for it.
The GIF is published to a dedicated orphan assets branch — no parent commit, media only — never to the pull request branch; one assets branch serves a whole pull request series (existing branches: `code-mode-ui-assets`, `pr-613-assets`). Publication works in a shallow single-branch scratch clone, commits as `assets: <what it shows> gif (#<pr>)`, and the pull request body embeds the blob URL with the required `?raw=true` suffix. Assets branches are append-only: merged pull request bodies reference their URLs forever, so an assets branch is never rewritten or deleted.
Recording itself stays side-effect-free; publication is a bounded final step the skill performs only when the task includes attaching the GIF to a pull request. The [record-browser-gif skill](../../../skills/record-browser-gif/SKILL.md) remains the current contract for the recording half.
The skill folds in the operational lessons recording earned: frames go under `.playwright-mcp/`, ignored by the repository `.gitignore` and created before capture, because the browser tool writes only under its allowed roots and resolves relative names against the repository root; each pull request stages its own built tree with a fresh scratch workspace and a new session per scenario, and servers are stopped by PID rather than a broad process-name pattern; transient states are captured by driving a slow foreground operation and polling a concrete DOM marker inside one browser-script call; completion predicates match an exact-text element rather than a substring; and the encoder runs with `GIF_SKILL_DIR` exported on its own line, per-frame durations holding the settled state longest, and both a JSON-summary check and a visual read of the encoded GIF.
## Alternatives considered
**Commit the GIF to the pull request branch.** Binary media merged into the default branch stays in history for every future clone and fetch; a demo GIF's value ends at review while its cost never does.
**Attach the GIF as a GitHub upload.** Drag-and-drop `user-attachments` uploads are not available to a command-line workflow, cannot be re-created or audited from the repository, and leave the media's lifecycle outside repository control.
**Store GIFs with Git LFS.** LFS still couples media to the code branch's history, adds an infrastructure dependency to every clone and CI fetch, and buys nothing over an isolated branch that ordinary git already supports.
**One assets branch per pull request.** A branch per pull request sprawls the ref namespace and multiplies scratch clones during a series; one branch per series keeps publication a single push while staying isolated from code history.
**Keep publication out of the recording skill.** That was the prior state; it preserved a clean boundary but made every pull request re-derive the same procedure. The boundary survives as an explicit gate — publication runs only when the task includes attaching the GIF to a pull request — instead of as omission.
**Leave the GIF optional per pull request.** Optional evidence disappears under schedule pressure exactly where it matters most; a GUI change reviewed without a recording asks reviewers to imagine the rendered result or rebuild the branch themselves.
## Consequences
Every GUI pull request carries visual evidence with stated provenance, and reviewers see the change without rebuilding the branch. Repository history stays free of media; the cost moves to append-only assets branches that grow forever, stay cheap to clone shallowly, and can never be deleted. Mandatory real-provenance recording adds a real-key, real-model round to every GUI pull request's workflow — deliberate, because that run is the evidence. The recording half remains locally reversible, and a GIF request whose task does not include attaching it to a pull request still ends at the verified local artifact.

# Agent Note: GUI PR 的 GIF 证据与 assets 分支发布
Status: implemented
[English](2026-07-26-gui-pr-gif-evidence-and-assets-branch.md) | 中文
## 问题
改变产品用户在 GUI 中所见行为的 PRPull Request此前只能通过文字描述和测试名称接受评审两者都无法展示渲染结果。[浏览器演示 GIF 录制](../../../skills/record-browser-gif/SKILL.md)对应的 skill技能能生成真实可信的本地 GIF但刻意止步于本地产物于是每个想展示 GIF 的 PR 都得各自重新摸索发布方式;而把 GIF 提交到 PR 分支从来不可接受:进入历史的二进制媒体会永久增大之后每一次克隆的体积。
录制流程本身也在靠一次次失败反复重新学习:截图写到浏览器工具允许的根目录之外或写入不存在的目录,会在截取时直接失败;跨多次工具调用轮询的瞬态 UI 状态会丢失,因为调用之间轮次已经结算;用子串匹配做完成判定会命中用户自己提示词的回显;在编码器命令上内联赋值环境变量则因参数先于赋值展开而不生效。
## 决策
每个改变产品用户可见 GUI 行为的 PR 都包含一个用 [record-browser-gif skill](../../../skills/record-browser-gif/SKILL.md) 录制的演示 GIF其来源必须真实从该 PR 自身分支树启动的真实服务器、真实 API 密钥、真实的模型轮次,并在嵌入处注明来源。只有当用户明确要求 fixture测试前置数据来源时才可使用 fixture。
GIF 发布到专用的孤儿orphanassets 分支上该分支没有父提交、只含媒体GIF 绝不进入 PR 自己的分支;一个 assets 分支服务整个 PR 系列(现有分支:`code-mode-ui-assets``pr-613-assets`)。发布在浅层单分支的临时克隆中进行,提交信息形如 `assets: <what it shows> gif (#<pr>)`PR 正文用带必需 `?raw=true` 后缀的 blob URL 嵌入。assets 分支只允许追加:已合并的 PR 正文会永远引用其 URL因此 assets 分支绝不重写或删除。
录制本身保持无副作用;发布是一个有边界的收尾步骤,仅当任务包含把 GIF 附到 PR 时才由该 skill 执行。[record-browser-gif skill](../../../skills/record-browser-gif/SKILL.md) 仍是录制部分的现行契约。
该 skill 还吸收了录制实践换来的操作经验:帧文件放在仓库 `.gitignore` 忽略的 `.playwright-mcp/` 目录下并在截取前先创建,因为浏览器工具只能写入其允许的根目录,相对文件名也相对仓库根目录解析;每个 PR 从自己构建的分支树启动服务,配以全新的临时工作区目录,每个录制场景新开会话,停止服务器时按 PID 精确匹配而不是用宽泛的进程名模式;瞬态状态靠驱动一个缓慢的前台操作、并在同一次浏览器脚本调用内轮询具体的 DOM 标记来截取;完成判定匹配精确文本元素而非子串;编码器在单独一行 export `GIF_SKILL_DIR` 之后运行,逐帧时长让最终稳定状态停留最久,并同时核对 JSON 摘要与目视检查编码后的 GIF。
## 曾考虑的替代方案
**把 GIF 提交到 PR 分支。**合入默认分支的二进制媒体会留在历史中,影响之后的每一次克隆和拉取;演示 GIF 的价值止于评审,代价却永不消失。
**作为 GitHub 附件上传。**拖拽产生的 `user-attachments` 上传对命令行工作流不可用,无法从仓库重建或审计,媒体的生命周期也脱离仓库的控制。
**用 Git LFS 存储 GIF。**LFS 仍把媒体耦合进代码分支的历史,给每次克隆和 CI 拉取增加一项基础设施依赖,相比普通 git 即可支持的隔离分支没有任何额外收益。
**每个 PR 一个 assets 分支。**按 PR 建分支会让 ref 命名空间蔓延,并在一个系列内成倍增加临时克隆;每个系列一个分支让发布只需一次推送,同时仍与代码历史隔离。
**把发布留在录制 skill 之外。**这是此前的状态;它保住了干净的边界,却让每个 PR 重新摸索同一套流程。这个边界如今以显式条件的形式保留:仅当任务包含把 GIF 附到 PR 时才执行发布,而不是靠省略来体现。
**让 GIF 在每个 PR 中保持可选。**可选的证据恰恰会在最需要它的进度压力下消失;没有录制的 GUI 变更评审,等于要求评审人自行想象渲染结果或重新构建分支。
## 后果
每个 GUI PR 都携带注明来源的可视证据,评审人无需重新构建分支即可看到变更。仓库历史保持不含媒体;代价转移到只追加的 assets 分支上:它们会持续增长、可以低成本地浅克隆、且永远不能删除。强制的真实来源录制给每个 GUI PR 的工作流增加一次真实密钥、真实模型轮次的运行,这是有意为之,因为这次运行本身就是证据。录制部分仍然在本地可撤销;任务不包含附到 PR 的 GIF 请求,仍以已验证的本地产物结束。

# Agent Note: Web client syntax highlighting — synchronous fine-grained shiki
Status: implemented
English | [中文](2026-07-26-web-syntax-highlighting-shiki.zh.md)
> Scope: the web client's one syntax-highlighting system — the dependency ruling, the singleton shape, the token-sheet contract, and the consuming surfaces. Fifth PR of the Code Mode UI stack; the [chat sub-call rows note](../feature/2026-07-26-code-mode-chat-subcall-rows.md) shipped the `run_code` program body this exists to make readable. Styling ground rules are owned by [the web styling ruling](2026-07-19-web-styling-system.md).
## Problem
The client rendered every code surface — markdown fences in assistant prose, the `run_code` program body, the details panel's args — as flat monospace text. The stack's primary payload is model-written TypeScript; unhighlighted programs are measurably harder to scan, and the repo already ships shiki-highlighted code on its VitePress site, so the web app was the one code-rendering surface without it.
## Decision
**Shiki in its synchronous fine-grained form, as one `ui-primitives` singleton, themed exclusively through CSS custom properties.**
- **Dependency**: `shiki/core` + `@shikijs/langs`, composed via `createHighlighterCoreSync` with `createJavaScriptRegexEngine({ forgiving: true })` — no oniguruma WASM, no async init, bundle-friendly. Grammar allowlist: `typescript` (embeds JS), `shellscript`, `json` — the languages the harness actually renders; everything else falls back to a geometry-identical plain block, never an error. Prior art: the VitePress site already renders all documentation code through shiki, and TextMate grammars materially beat regex highlighters on TypeScript — the payload that matters here.
- **Singleton**: `ui-primitives/src/markdown/highlight.ts` creates one `HighlighterCore` per document and exposes `highlightToHtml(code, lang)` (undefined = render plain). Engine + grammar construction is a ~120-175ms long task, so the module pre-warms the singleton in a deferred task at plugin boot (the lazy path stays as the correctness fallback), keeping the cost off the render path where a stream's finalize swap would jank. The alias table is a `Map`, not an object: fence info strings are assistant-authored, so a label like `constructor` must miss instead of resolving an inherited property and crashing shiki. The shared `CodeBlock` component owns both arms; its shiki arm injects the generated span tree via `dangerouslySetInnerHTML` — sanctioned because shiki emits a static span tree computed from the code text (no user HTML passes through, no scripts/handlers), shiki's own documented consumption path.
- **Theming**: shiki's `createCssVariablesTheme` routes every token color through `--shiki-*` custom properties; the VALUES live in a new `ui-theme/styles/shiki.css` token sheet (light on `:root`, dark on `body[data-ds-dark-theme]` — the same cascade as every other sheet), imported by the shell's `base.css` chain. Component CSS stays tokens-only; no literal color ever enters JS or component sheets. Background/foreground alias the existing markdown code-block tokens so highlighted and plain blocks agree.
- **Surfaces**: markdown fences (`MarkdownText`'s `pre` component routes single-string fences through `CodeBlock`), the `run_code` expanded program body (ToolRow's code variant, `lang="typescript"`), and the details panel's Input args (`lang="json"`). Output stays plain deliberately — tool output is arbitrary text, and guessing a grammar would mis-highlight more than it helps.
## Alternatives considered
**`rehype-highlight`/lowlight.** Runner-up: naturally sync and ~⅓ the bundle, but regex-grammar fidelity on TypeScript is visibly worse, and the repo would then run two highlighter systems (site: shiki, app: highlight.js) with two theming vocabularies.
**Full `shiki` bundle or the oniguruma WASM engine.** Rejected: the full bundle ships every grammar/theme; WASM needs async loading the sync client boot deliberately avoids. The fine-grained core with three grammars keeps the cost proportional to actual use.
**Highlight in a worker / async.** Rejected: the payloads are small (programs, fences, args); the synchronous JS engine tokenizes them in microseconds, and async introduces a flash-of-unhighlighted-code plus render-machinery churn for no measured need.
## Consequences
One code surface for every consumer — a future surface imports `CodeBlock` and inherits highlighting, theming, and the plain fallback. The bundle grows by the shiki core + three grammars (paid once in `ui-primitives`). Token colors are the first `--shiki-*` sheet; a theme package registering alias overrides extends them like any other token. jsdom specs pin the token-span structure, alias resolution, both fallback arms, and the fence route; the existing built-bundle snapshot and browser e2e cover the assembled path.

# Agent Noteweb client 的语法高亮——同步细粒度的 shiki
Status: implemented
[English](2026-07-26-web-syntax-highlighting-shiki.md) | 中文
> 范围web client 唯一的一套语法高亮体系——依赖裁决、单例形态、token 表契约与各消费表面。本篇是 Code Mode UI 堆叠 PRPull Request链的第五个 PR[chat 子调用行 Agent Note](../feature/2026-07-26-code-mode-chat-subcall-rows.md)交付了 `run_code` 程序正文,而本体系存在的意义正是让它可读。样式的基本规则归 [Web 样式体系裁决](2026-07-19-web-styling-system.md)所有。
## 问题
client 过去把每一处代码表面——assistant 正文里的 markdown 围栏代码块、`run_code` 程序正文、details 面板的参数——一律渲染成不带高亮的等宽纯文本。本堆叠 PR 链的主要载荷是模型撰写的 TypeScript未经高亮的程序扫读起来明显更吃力而仓库已经在自家 VitePress 站点上交付经 shiki 高亮的代码,于是 web 应用成了唯一不带语法高亮的代码渲染表面。
## 决策
**采用同步细粒度形态的 shiki作为 `ui-primitives` 里的一个单例,主题化完全经由 CSS 自定义属性完成。**
- **依赖**`shiki/core` + `@shikijs/langs`,经 `createHighlighterCoreSync` 搭配 `createJavaScriptRegexEngine({ forgiving: true })` 组装——不带 oniguruma WASM、没有异步初始化、对 bundle 友好。语法grammar白名单`typescript`(内嵌 JS`shellscript``json`——即 harness 实际会渲染的那几种语言其余一律回退到几何完全一致的纯文本块绝不报错。先例VitePress 站点已经通过 shiki 渲染全部文档代码;而在 TypeScript正是此处要紧的载荷TextMate 语法实质性优于正则高亮器。
- **单例**`ui-primitives/src/markdown/highlight.ts` 为每个 document 创建一个 `HighlighterCore`,并公开 `highlightToHtml(code, lang)`undefined 即渲染为纯文本)。引擎加语法的构建是一次约 120-175ms 的长任务,因此模块在插件启动时用延迟任务预热单例(惰性路径保留为正确性兜底),把这笔开销挪出渲染路径——否则流式 finalize 交换的那一刻会卡顿。别名表用 `Map` 而非对象fence 信息串由 assistant 撰写,诸如 `constructor` 这样的标签必须落空,而不是解析到继承属性并让 shiki 崩溃。共享的 `CodeBlock` 组件同时拥有两条分支;其 shiki 分支经 `dangerouslySetInnerHTML` 注入生成的 span 树——此用法获准,因为 shiki 输出的是从代码文本计算出的静态 span 树(不流经任何用户 HTML没有脚本或事件处理器这正是 shiki 自身文档载明的消费路径。
- **主题化**shiki 的 `createCssVariablesTheme` 让每一种 token 颜色都经由 `--shiki-*` 自定义属性路由;取值本身住在新增的 `ui-theme/styles/shiki.css` token 表里(亮色在 `:root`、暗色在 `body[data-ds-dark-theme]`——层叠方式与其余每张样式表相同),由壳的 `base.css` 导入链引入。组件 CSS 保持只用 token任何字面颜色都不进入 JS 或组件样式表。背景/前景以别名指向既有的 markdown 代码块 token使高亮块与纯文本块彼此一致。
- **表面**markdown 围栏代码块(`MarkdownText``pre` 组件把单字符串围栏路由到 `CodeBlock`)、`run_code` 展开后的程序正文ToolRow 的 code 变体,`lang="typescript"`),以及 details 面板的 Input 参数(`lang="json"`)。输出有意保持纯文本——工具输出是任意文本,硬猜一种语法,带来的误高亮会多于帮助。
## 曾考虑的替代方案
**`rehype-highlight`/lowlight。** 屈居次选天然同步bundle 体积约为三分之一,但基于正则的语法在 TypeScript 上的保真度肉眼可见地更差,而且仓库将从此同时运行两套高亮体系(站点用 shiki、应用用 highlight.js、维护两套主题化词汇。
**完整的 `shiki` bundle或 oniguruma WASM 引擎。** 否决:完整 bundle 会带上每一种语法和主题WASM 需要异步加载,而这正是同步的 client 启动刻意规避的。细粒度 core 加三种语法,让成本与实际用量成正比。
**在 worker 中高亮/异步高亮。** 否决:载荷都很小(程序、围栏代码块、参数);同步 JS 引擎微秒级就能把它们 token 化,而异步会引入一段未高亮代码的闪现,外加渲染机制的扰动,却没有任何实测得出的需要。
## 后果
所有消费方共用同一个代码表面——未来的新表面导入 `CodeBlock` 即继承高亮、主题化与纯文本回退。bundle 的增量是 shiki core 加三种语法(在 `ui-primitives` 中一次性支付。token 颜色是第一张 `--shiki-*` 表;注册别名覆写的主题包扩展它们的方式与扩展任何其他 token 无异。jsdom spec 锁定 token span 结构、别名解析、两条回退分支与围栏路由;既有的已构建 bundle 快照和浏览器 e2e 覆盖组装后的路径。
