**`describe()` grows layers and structural secret redaction.** `SettingsDescriptor` carries `base`/`user` beside the effective value, so the form marks "overridden" by presence in the user layer, not value inequality (an override *equal* to the base is still an override). `describe({ redactSecrets: true })` — mandatory at every wire face — strips `role('secret')` subtrees from all three layers via a pure structural walk of the schema (object/dict/array containers; a secret-role subtree is one opaque leaf) and enumerates the stripped slots as `{path, set}`, so a page can render write-only inputs without ever receiving a value.
**The Host identifies and opens the local settings document.** The settings seam exposes optional `documentPath` provider metadata and a `prepareDocument()` operation; `settings-local` returns its fully resolved custom or `$DSH_HOME/settings.yaml` filename and exclusively creates an absent empty document with owner-only permissions, while non-file providers retain the base `undefined`. The loopback-only `settings.describe` response carries only the boolean `hasDocument` capability beside the redacted namespace views. `ui-settings-general` registers a `settings.action` entry only on loopback pages, shows it only after the metadata confirms that a provider-owned local document can be prepared, and invokes pathless `settings.openDocument`; the Host resolves the provider path again before a text-document handoff (`open -t` on macOS so an arbitrary YAML file association cannot redirect the gesture, `xdg-open` on Linux, and `Invoke-Item` on Windows). Generic workspace paths retain the existing default-application handoff. The browser neither derives `$DSH_HOME` nor receives a filesystem target; remote pages make no privileged settings read for this action.

Generic workspace paths retain the existing default-application handoff. The browser neither derives `$DSH_HOME` nor receives a filesystem target; remote pages make no privileged settings read for this action.
**The llm seam declares configurability and announces topology.** `registerConfigurableProviders()` is an all-or-nothing, fiber-scoped directory of `{provider, displayName, settingsNs, settingsPath}` — the addressing a config page needs to open the right settings subtree for a route that may not exist yet; `listConfigurableProviders()` merges with live routes in the wire handler so undeclared live routes still report active. The zero-payload `'llm/adapters-updated'` event fires from all four registration/unregistration commit points with contained listener dispatch (INVARIANT rethrow), following the settings/commands precedent. `llm-deepseek`'s route renamed to `deepseek-official` because the pi-ai catalog legitimately owns `deepseek` as an aggregator entry; pre-release stance, no alias.
**A hand-written editor over a schema model layer.** `dsh-client-schema-form` rehydrates the wire's `toJSON()` envelope into live schemastery nodes for validation, path resolution, and immutable draft editing — but no generic rendering: the first cut shipped a full schema-driven form renderer, and the resulting page was an unstyled schema dump (every advanced field flattened onto the card, raw field names as labels, the `retryPolicy` unsupported-fallback in the main flow). The user chose the hand-written direction over adding a hint/grouping system, and a second round removed the reference input entirely: the card's primary field is one **API key** input, a whole-section provider without a configured key opens as its setup card, and the collapsed 自定义设置 fold carries the curated per-family extras (`baseURL` for both families, `reasoningEffort` for deepseek / `reasoning` for pi-ai, plus direct DeepSeek model rows with `id`, `name`, and `contextWindow`). Existing model fields outside that visible set survive array edits; retry policy, timeouts, and other fields remain owned by `settings.yaml`. Validation still runs the rehydrated schema before writing, while adapter-specific checks reject catalog invariants that the serialized schema cannot express. The card's colors resolve through the `--dsw-alias-*` design tokens; it had named `--border`/`--surface`/`--text-*`, which nothing in this app defines, so it rendered their light-mode fallbacks and stayed light under the dark theme. The model catalog takes the row shape the pi-ai provider form introduces: one bordered entry per model, id and display name on the row, and the capacities behind the row's own disclosure, so the two editors read as one design rather than diverging once both land. Every field keeps the indexed `aria-label` that names it. Both capacities are text fields reading a decimal `K`/`M` suffix (`1M` is 1000K, matching how capacities are quoted) and storing the plain count: a field holds the typed text while it has focus, because re-deriving it from the parsed count on every keystroke would rewrite `1000` to `1K` mid-word, and text that does not parse stays on screen so the save-time rejection names a row the user can still see. The shared class names carry this file's token spellings, not that branch's: `--dsw-alias-border-subtle`, `--dsw-alias-text-tertiary`, and `--dsw-alias-text-primary` are undeclared, so they resolve to the light-mode literals in their fallback slots — the defect this section was moved off. A styles test now rejects any `--dsw-*` name the token sheet does not declare, so the next editor to name one fails rather than shipping a light-only surface.
**The Models page is a three-domain join with seam-shaped apply semantics.** Rows are configured providers; the add card's select is the dormant directory remainder. Route liveness still gates readiness and invalidates the join, but the page does not render it as provider status because configuration presence and runtime availability are distinct. The key path stays reference-shaped without ever showing a reference: a typed key stores **write-only** through `credentials.set` under the profile's `apiKeyEnv`, deriving `<ROUTE>_API_KEY` when none exists (the pi-ai profile records the derivation), so `settings.yaml` never carries a key value. Profile edits and removals land as minimal path-addressed `settings.mutate` operations against the redacted user section, which never names a secret the page did not receive. Removing a user-layer provider first opens a localized model-provider confirmation dialog; cancellation, its close button, and its mask leave the profile untouched, while the destructive confirmation submits the single unset and blocks duplicate submission until it settles. DeepSeek's model list is array-replace configuration: inherited effective rows remain visible until the first edit materializes the complete list in the user layer, and reset unsets the list override.

## Consequences
The whole loop is pinned keyless in the browser lane (`apps/web/tests/models-settings.e2e.ts`): the add card offers the dormant pi-ai catalog, adding `minimax-cn` with a typed key writes the reference-only profile into `settings.yaml`, stores the value into the harness home's `.env` under the derived `MINIMAX_CN_API_KEY`, registers the route live on the topology frame, and the customized fold merges `reasoning` beside the reference — zero model calls, ARIA goldens for the add-card, configured, and delete-confirmation states, plus a scaffold `harnessHome` so tests never touch a real `~/.dsh` (the provider under test is one whose derived reference cannot collide with a developer's exported keys). The settings-shell scenario intercepts the pathless native intent; seam, provider, wire, React, and native-opener tests separately pin provider absence, custom-path resolution, absent-file materialization, owner-only permissions, hidden remote/unavailable states, duplicate-click collapse, localized failure, macOS text-editor dispatch, and Linux/Windows desktop dispatch. The removal scenario proves cancellation leaves the profile intact, confirmation removes it, and the intentionally retained credential survives. The DeepSeek onboarding fixture edits the default catalog into a user-owned list, persists an arbitrary model id/name/context window, removes the active row, and observes the model selector's empty-selection fallback. The rename touched 239 files (fixtures, goldens, docs, python) in one commit with no compatibility alias. The renderer replacement cost one commit and no wire change: apply semantics, redaction, and the directory join were renderer-agnostic all along. Deferred: a per-row models preview (the picker already lists models), a page address for live routes that never declared configurability, and explicit removal of a provider's retained credential.

# Agent Note: the code-runtime seam owns portable-identifier exclusions
Status: implemented
English | [中文](2026-07-31-code-runtime-portable-identifier-seam.zh.md)
## Problem
The code-runtime seam promises that a binding-namespace list valid on one backend is valid on every backend, so a Code Mode consumer can hand the same bindings to any registered runtime without knowing its language. The first backend, `dsh-code-runtime-worker`, privately owned the identifier rules that enforce part of that promise: an `IDENTIFIER` regex that allowed the JS-only `$`, a `RESERVED_WORDS` set holding only ECMAScript keywords, and a `RESERVED_ERROR_PROPERTIES` set of three JS `Error` slots. Those rules described the worker's own language, not the seam's portability contract.
A second backend written against a different language (CPython, arriving in a later PR of this stack) would either re-declare its own rules — letting `lambda` pass the worker and fail Python, or `$tools` pass the worker and fail every non-JS backend — or import the worker's, inverting the dependency so the seam's implementation reached into a sibling implementation. Neither keeps the portability promise real: it would hold only for the backend a caller happened to test against.
## Decision
The seam package (`@deepseek-ai/dsh-code-runtime`) exports the portable-identifier exclusion contract as four named constants, and every backend imports them rather than re-declaring:
- `PORTABLE_RESERVED_WORDS` — the union of ECMAScript and Python reserved words. A namespace global or error-class name matching any is refused on all backends, so `lambda` is refused even though it is a legal JS parameter name. Adding a language widens this union, which is a deliberate breaking review of existing binding names.
- `RESERVED_BINDING_GLOBALS` — globals some backend owns in the program's namespace: `console` (the worker's log capture), `__dsh_main__`/`__builtins__`/`__name__` (the Python bootstrap's wrapper and seeded module globals), and `__debug__` (not a seeded slot but a CPython compile-time constant that rejects assignment, so an injected global under that name is unreachable — the same portability split by a different mechanism). Refused everywhere so a namespace list cannot pick a name that works on one backend and collides on another.
- `RESERVED_ERROR_MEMBERS` — error-member names every backend refuses: the JS `Error` slots (`name`, `message`, `stack`) and Python's exception-protocol members (`args`, `with_traceback`, `add_note`).
- `DUNDER_MEMBER` — the dunder-form regex (`__x__`, non-empty middle), refused as an error member wholesale because several are constrained CPython descriptors whose exact set is an interpreter-version detail.
The seam also narrows the portable identifier subset to `[A-Za-z_][A-Za-z0-9_]*` (documented on `CodeBindingNamespace.global` and `CodeBindingErrorClass`), dropping the JS-only `$`. The worker consumes the shared constants directly by their seam names — `PORTABLE_RESERVED_WORDS` for both binding-global and error-class names, `RESERVED_BINDING_GLOBALS` for backend-owned slots, `RESERVED_ERROR_MEMBERS` plus `DUNDER_MEMBER` for error members — with no local re-alias; its `IDENTIFIER` regex loses `$`.
The constants live at the seam even though only one backend ships in this PR: the whole point is that the contract is language-agnostic and owned above any single language. A backend that violated it would be the bug, and the shared set is where a reviewer looks to see what "portable" means.
## Scope
This PR delivers only the seam extension and the worker's adoption of it. No Python backend, `py-types` renderer, or Code Mode language dispatch ships here — they are later PRs in the stack that depend on these exports. The seam README's worker-only wording is left unchanged for the same reason: linking to a `dsh-code-runtime-python` README that does not yet exist would break the dead-link gate.
`RESERVED_BINDING_GLOBALS` currently encodes the not-yet-merged Python bootstrap's concrete design: it seeds exactly `__builtins__`/`__name__` and wraps the program under `__dsh_main__`. The Python-backend PR that seeds any additional module global (`__doc__`, `__loader__`, `__spec__`, `__file__`, `__package__`, …) MUST widen this set in the same change, exactly as adding a language widens `PORTABLE_RESERVED_WORDS` — a name the bootstrap seeds but the set omits is the portability split this contract exists to prevent.
## Alternatives considered
**Each backend declares its own exclusions.** Rejected: it makes the portability promise per-backend. A binding list the caller tested on the worker could be refused by Python, which is exactly the split the seam exists to prevent.
**The Python backend imports the worker's constants.** Rejected: it inverts the dependency — the seam's implementations would reach into a sibling implementation for a contract neither owns. The contract belongs above both, at the seam.
**Keep `$` in the portable identifier subset.** Rejected: `$` is JS-only spelling. Allowing it would let `$tools` pass the worker and fail every non-JS backend, breaking portability for a purely cosmetic gain.
## Consequences
Bought: one place — the seam package — defines what a portable binding name is, and every backend enforces the same contract by import. A namespace list valid on one backend is valid on all, verifiably, not by coincidence of which backend the caller tested.
Cost: existing worker callers using a `$`-containing global now fail identifier validation. Under the pre-release stance this is a corrected foundation, not a compatibility break to shim. The worker's seam-misuse tests gain cases for `$tools`, Python exception members (`args`), dunders (`__dict__`), and a Python-owned global (`__dsh_main__`), proving the shared set is enforced from the worker side.

# Agent Notecode-runtime seam 拥有可移植标识符排除集
Status: implemented
[English](2026-07-31-code-runtime-portable-identifier-seam.md) | 中文
## Problem
code-runtime seam 承诺:在一个后端上有效的绑定命名空间列表,在每个后端上都有效,因此 Code Mode 消费方可以把同一组绑定交给任何已注册的运行时,而不必知道它的语言。首个后端 `dsh-code-runtime-worker` 私自拥有了执行这项承诺一部分的标识符规则:一个允许 JS 专有 `$``IDENTIFIER` 正则、一个只含 ECMAScript 关键字的 `RESERVED_WORDS` 集合,以及一个含三个 JS `Error` 槽位的 `RESERVED_ERROR_PROPERTIES` 集合。这些规则描述的是 worker 自身的语言,而非 seam 的可移植性契约。
一个针对不同语言CPython将在本 stack 后续 PR 中到来)编写的第二后端,要么重新声明自己的规则——让 `lambda` 通过 worker 却在 Python 上失败,或让 `$tools` 通过 worker 却在每个非 JS 后端上失败——要么导入 worker 的规则,从而反转依赖,使 seam 的一个实现伸手进入另一个兄弟实现。二者都无法让可移植承诺成真:它只对调用方恰好测试过的那个后端成立。
## Decision
seam 包(`@deepseek-ai/dsh-code-runtime`)以四个具名常量导出可移植标识符排除契约,每个后端导入它们而非重新声明:
- `PORTABLE_RESERVED_WORDS`——ECMAScript 与 Python 保留字的联集。任何命名空间 global 或 error-class 名称匹配其中之一,都在所有后端上被拒绝,因此 `lambda` 即便是合法的 JS 参数名也被拒绝。新增一门语言即扩宽此联集,这是对现有绑定名称的一次有意的破坏性复审。
- `RESERVED_BINDING_GLOBALS`——某个后端在程序命名空间中拥有的 global`console`worker 的日志捕获)、`__dsh_main__`/`__builtins__`/`__name__`Python bootstrap 的包装器与预置模块 global以及 `__debug__`(不是 seed 的槽位,而是 CPython 编译期常量,赋值会被拒,故以该名注入的 global 不可达——同一种可移植性分裂,只是机制不同)。在所有后端上被拒绝,使命名空间列表无法选到一个在某后端能用、在另一后端冲突的名称。
- `RESERVED_ERROR_MEMBERS`——每个后端都拒绝的 error-member 名称JS `Error` 槽位(`name``message``stack`)与 Python 异常协议成员(`args``with_traceback``add_note`)。
- `DUNDER_MEMBER`——dunder 形式正则(`__x__`,非空中缀),作为 error member 被整体拒绝,因为其中若干是受约束的 CPython 描述符,其确切集合是解释器版本细节。
seam 同时把可移植标识符子集收窄为 `[A-Za-z_][A-Za-z0-9_]*`(记录在 `CodeBindingNamespace.global``CodeBindingErrorClass` 上),去掉 JS 专有的 `$`。worker 直接以 seam 名消费这些共享常量——binding-global 与 error-class 名称用 `PORTABLE_RESERVED_WORDS`、后端拥有槽位用 `RESERVED_BINDING_GLOBALS`、error member 用 `RESERVED_ERROR_MEMBERS``DUNDER_MEMBER`——不再本地起别名;其 `IDENTIFIER` 正则去掉 `$`
尽管本 PR 只交付一个后端,这些常量仍置于 seam要点正是该契约与语言无关且拥有权在任何单一语言之上。违反它的后端才是 bug而共享集合正是复审者查看"可移植"含义的地方。
## Scope
本 PR 只交付 seam 扩展与 worker 对它的采用。这里不交付任何 Python 后端、`py-types` 渲染器或 Code Mode 的语言分发——它们是本 stack 中依赖这些导出的后续 PR。seam README 中仅描述 worker 的措辞保持不变,理由相同:链接到一个尚不存在的 `dsh-code-runtime-python` README 会破坏死链 gate。
`RESERVED_BINDING_GLOBALS` 当前编码了尚未合并的 Python bootstrap 的具体设计:它恰好 seed `__builtins__`/`__name__`,并把程序包装在 `__dsh_main__` 之下。任何 seed 额外模块 global`__doc__``__loader__``__spec__``__file__``__package__` 等)的 Python 后端 PR 必须在同一改动中扩宽此集合,正如新增一门语言即扩宽 `PORTABLE_RESERVED_WORDS`——bootstrap 会 seed 却不在集合中的名称,正是本契约要防止的可移植性分裂。
## Alternatives considered
**每个后端声明自己的排除集。** 拒绝:这让可移植承诺变成逐后端成立。调用方在 worker 上测过的绑定列表可能被 Python 拒绝,而这正是 seam 存在要防止的分裂。
**Python 后端导入 worker 的常量。** 拒绝这反转依赖——seam 的实现会为一个二者都不拥有的契约伸手进入兄弟实现。契约属于二者之上,即 seam。
**在可移植标识符子集中保留 `$`。** 拒绝:`$` 是 JS 专有拼写。允许它会让 `$tools` 通过 worker 却在每个非 JS 后端上失败,为纯粹表面的好处破坏可移植性。
## Consequences
获得一个地方——seam 包——定义什么是可移植绑定名称,每个后端通过导入执行同一契约。在一个后端上有效的命名空间列表在所有后端上都有效,这是可验证的,而非取决于调用方测试了哪个后端的巧合。
代价:现有使用含 `$` global 的 worker 调用方现在会在标识符校验时失败。在预发布立场下这是一次被纠正的地基,而非需要 shim 的兼容性破坏。worker 的 seam-misuse 测试新增了 `$tools`、Python 异常成员(`args`、dunder`__dict__`)与一个 Python 拥有的 global`__dsh_main__`)等用例,从 worker 侧证明共享集合被执行。

# Agent Note: Turn-tail IconActions require a completed turn
Status: implemented
English | [中文](2026-08-05-turn-tail-actions-require-a-completed-turn.zh.md)
## Problem
Assistant IconActions were derived from the finalized transcript alone: the last content-text assistant of each turn owned the row. That quantity is stable only after the turn closes. While a turn is still producing steps, the narration a model writes before a tool call *is* the last content assistant so far, so it took the row for as long as the tool ran and then lost it to the next step's text. Readers saw copy, branch, and a clock appear under an intermediate sentence, shift the flow by one 28px row, and disappear. The row was also incoherent in that state: its branch control was already disabled through `turnEnds`, and its `Ran for` label was already withheld through `turnTimings`, so only copy worked.
The [message chrome decision](../feature/2026-07-29-web-message-icon-actions-and-clock.md) always claimed mid-turn narration stays chrome-free; the derivation never carried a completion signal to make that true.
## Decision
`assistantActionsSeqs` takes `ConversationSnapshot.turnEnds` and grants the row only within a turn that has a `turn/end` in the window. Ownership inside a completed turn is unchanged: its last content-text assistant. A turn still producing steps grants nothing, so its narration never mounts the row, and the seat appears once, under the settled answer, when the turn closes.
This is the same completion fact the branch control and the run-time label already use, so the three parts of one row now agree. Turn completion is read from the durable `turn/end` event rather than inferred from `running`, the streaming partial, or in-flight tool calls, matching the [completed-turn-tail decision](2026-08-02-message-fork-actions-require-completed-turn-tail.md). Every reason kind closes a turn, so an aborted turn's frozen tail keeps its footer, and a crash-orphaned turn receives its `turn/end` from log repair on load.
`hasContentText` moves to `chat-flow.ts` and `AssistantMarkdown` imports it, so the ownership gate and the mount gate cannot drift apart.
## Alternatives considered
**Withhold by naming the open turn from `running` plus the streaming partial or the first in-flight tool call.** This shipped briefly in the original change and was then dropped. It infers completion instead of reading it, needs a special case so a turn accepted before its first step does not strip the previous answer's seat, and is the inference the completed-turn-tail decision rejected for the branch control. `turnEnds` answers the same question per turn with no inference and no special case.
**Leave the row mounted mid-turn and disable its controls.** Rejected: mid-turn narration is not a degraded answer, it is not the answer. Copy would still write an intermediate sentence, and the row would still move to the real tail at turn end.
**Keep the row under every finalized content node permanently.** Rejected again here for the reason the original decision gave: repeating copy, branch, and a clock under every step clutters the flow. It also does not solve the reported problem, since the branch control is only meaningful on the tail.
## Consequences
A running turn carries no message footer below the user bubble that triggered it, while every earlier completed turn keeps its own; the seat appears once when `turn/end` lands, which adds one 28px row under the settled answer at that moment. A turn whose `turn/end` is outside the loaded window grants nothing, which cannot arise from paging because a turn's end follows its own nodes. `apps/web/tests/turn-tail-actions.e2e.ts` pins both states through the assembled application: a `hang` sidecar on the second model call parks a turn whose first step narrated before calling bash, and the two goldens hold the parked flow and the flow after stopping. Package tests cover the derivation directly and the running-turn render.

# Agent Note: 轮次尾部 IconActions 要求轮次已完成
Status: implemented
[English](2026-08-05-turn-tail-actions-require-a-completed-turn.md) | 中文
## 问题
assistant IconActions 此前只从已定稿的 transcript文本记录推导每个轮次中最后一条含内容文本的 assistant 拥有该行。这个量只有在轮次关闭后才稳定。轮次仍在产出步骤时,模型在工具调用前写下的叙述就是当时该轮次的最后一条内容 assistant于是它在工具执行期间取得该行等下一步的文本落定又把它交出去。读者会看到复制、分支和时钟出现在一句中间叙述下方把流程推开一行 28px然后消失。该行在这个状态下本身也是残缺的分支控件已经通过 `turnEnds` 判定为禁用,`Ran for` 标签已经通过 `turnTimings` 判定为不显示,只有复制可用。
[消息 chrome 决策](../feature/2026-07-29-web-message-icon-actions-and-clock.md)一直声称轮次中间的叙述不带 chrome但推导过程从未拿到能让这句话成立的完成信号。
## 决策
`assistantActionsSeqs` 接收 `ConversationSnapshot.turnEnds`,只在事件窗口中存在该轮次 `turn/end` 时才授予该行。已完成轮次内部的归属不变,仍是其最后一条含内容文本的 assistant。仍在产出步骤的轮次不授予任何座位因此其叙述不会挂载该行轮次关闭时座位在已定稿答案下方一次性出现。
这与分支控件和运行时长标签使用的完成事实相同,因此同一行的三个部分现在口径一致。轮次是否完成读自持久的 `turn/end` 事件,而不是从 `running`、流式 partial 或在途工具调用推断,与[已完成轮次尾部决策](2026-08-02-message-fork-actions-require-completed-turn-tail.md)一致。任何 reason 类别都会关闭轮次,因此已中止轮次冻结的尾部保留其操作栏,而崩溃遗留的开放轮次会在加载时由日志修复补上 `turn/end`
`hasContentText` 移入 `chat-flow.ts`,由 `AssistantMarkdown` 导入,使归属门控与挂载门控无法各自漂移。
## 考虑过的替代方案
**用 `running` 加流式 partial 或第一个在途工具调用指认开放轮次,据此扣留。** 这一做法曾在最初的变更中短暂存在,随后被删除。它推断完成状态而不是读取完成状态,还需要一个特例,避免轮次已被接受但尚未产出第一步时把上一条回答的座位取走;这正是已完成轮次尾部决策为分支控件否决过的推断。`turnEnds` 按轮次回答同一个问题,不需要推断,也不需要特例。
**轮次进行中保留该行,只把控件置为不可用。** 不予采纳:轮次中间的叙述不是一个降级的答案,它根本不是答案。复制仍然会写入一句中间文本,该行在轮次结束时仍然要移动到真正的尾部。
**让每个已定稿的内容节点长期保留该行。** 在此重新否决,理由与最初的决策相同:在每一步下重复复制、分支和时钟会打乱流程。它也解决不了本次报告的问题,因为分支控件只有落在尾部才有意义。
## 后果
运行中的轮次在触发它的用户气泡之下不再有任何消息操作栏,而此前每个已完成轮次仍保留各自的座位;座位在 `turn/end` 到达时一次性出现,此刻已定稿答案下方会多出一行 28px。`turn/end` 落在加载窗口之外的轮次不授予座位,而翻页不会造成这种情况,因为一个轮次的结束事件排在它自己的节点之后。`apps/web/tests/turn-tail-actions.e2e.ts` 通过组装后的应用钉住两种状态:`hang` sidecar 作用在第二次模型调用上,把一个首步先叙述再调用 bash 的轮次挂住,两份 golden 分别记录挂起中的流程和停止之后的流程。包级测试直接覆盖该推导以及运行中轮次的渲染结果。

Pasting a key containing an emoji, CJK text, or a full-width punctuation mark into the web Models page reported a successful save. The first turn then failed with `Cannot convert argument to a ByteString because the character at index 7 has a value of 55357 which is greater than 255` — the index and code point are UTF-16 internals with no action attached, and they disclose the code point of one character of the key. `llm-deepseek` produced this because `fetch` builds the `Bearer` header inside the `try` in [adapter.ts](../../../../packages/llm/llm-deepseek/src/adapter.ts), whose `catch` labels every failure `TRANSPORT`; that label is in `DEFAULT_RETRYABLE_CODES`, so a permanent, deterministic fault was also retried three times.
`llm-pi-ai` was worse on the same input. Its discovery probe builds the same header with a bare `fetch` in [discovery.ts](../../../../packages/llm/llm-pi-ai/src/discovery.ts) and wrapped every failure as `could not reach <url>`, so a local key fault was reported as an unreachable network. The probe is reachable from the unsaved draft: `ProviderEditor` puts the typed `keyDraft` into its probe request, so the model-listing button sent an illegal key before anything was stored.
Whitespace passed every check. `ProviderEditor` tested `keyDraft.length` and `resolveAdapterOptions` tested `config.apiKey.length`, so a key of three spaces stored and then authenticated as `Bearer` plus blanks. `llm-pi-ai` rejected an empty literal `apiKey` in `resolveProfiles`, but applied no check whatsoever to a credential- or environment-sourced key — the path the Models page writes, and therefore the path users actually take.
Sources: deepseek-harness#1594 and #1595; dsh-external#247, #249, #266, and #210.
## Decision
One rule defines a legal key: **after trimming, non-empty, and every character within `[\x21-\x7E]`** — printable ASCII, space excluded.
This single predicate covers every input the sources list: empty, leading and trailing whitespace, interior whitespace, C0 control characters, emoji, CJK text, and full-width punctuation. It is also exactly the constraint that produced the ByteString failure, so the two issues close on one definition rather than on two coincidentally related fixes.
A second, narrower rule catches a pasted environment line: input matching `^[A-Z][A-Z0-9_]*=[^=]` or wrapped in matching quotes is refused. Restricting the prefix to upper-case keeps real keys clear of it — `sk-` forms break the identifier match at the hyphen — and requiring a non-`=` character after the separator keeps base64 padding clear of it too. It reports the same format failure as an illegal character rather than its own message: the reader's next move is identical either way, so a separate line would name a cause without changing what to do.
### Invariants belong at every layer; heuristics belong where the human is
The charset rule is an invariant. A non-ASCII character *cannot* travel in a header value for any provider, so enforcing it in the browser, in each resolver, and on every credential read is consistent by construction rather than by agreement.
The shape rule is a guess about how people paste, so it runs **only in the browser**. `llm-pi-ai` fronts OpenAI, Anthropic, and arbitrary hand-declared gateways whose key formats this repository does not own; a gateway issuing a key shaped like `TENANT1=abc` would, if the rule ran in the resolver, be locked out with no escape — the settings page would refuse it and a hand-written `.env` would be rejected on read. Confining the heuristic to the surface where the paste happens keeps the environment as the way through.
### Absence is a configuration state, not a missing key
"No API key" means three different things here, and only one of them is an error. The rule applies to a value that was *provided*; deciding whether one was provided at all stays with each caller.
**Omitted.** A profile naming neither `apiKey` nor `apiKeyEnv` is authenticated by something other than a harness-held key. `routeAuth` in [provider.ts](../../../../packages/llm/llm-pi-ai/src/provider.ts) keeps the installed catalog provider's own auth precisely so provider-native ambient discovery survives, and `openai-codex` — shipped in that catalog — authenticates through OAuth and refuses an explicit key outright. `namesCredential` carries this distinction. In `llm-deepseek`, an absent `apiKey` likewise falls through to `apiKeyEnv`. Omission is never validated.
**A blank field in the web UI.** The key input opens empty even for a provider whose key is already stored — the `keyStored` copy reads "Configured — enter a new value to replace" — so blank means *keep what is stored*. `ProviderEditor` skips `credentials.set` entirely when the draft is empty, and that stays a no-op: a blank field never blocks submit, or editing a base URL would demand re-entering the key.
**Provided, but empty or whitespace-only.** What this means depends on what absence selects for that surface, and the two adapters differ for a reason. In `llm-pi-ai` it is an error, because absence there switches authentication mode — to the installed provider's ambient discovery or OAuth — so a blank key leaves genuine ambiguity about which was meant; its wording names the legitimate alternative rather than just refusing (*has an empty apiKey; omit it to use ambient authentication*). In `llm-deepseek` absence merely selects a different *source* for the same key, `apiKeyEnv`, so a blank literal resolves through that fallback exactly as an omitted one does. In the browser it is always a failure, on both cards: the field is where a person just typed, and silently discarding what they typed is never the right answer.
`normalizeApiKey` therefore takes `string`, never `string | undefined`.
### Where the rule lives
`normalizeApiKey` is a module of the `dsh-llm` seam, beside [attribution.ts](../../../../packages/llm/llm/src/attribution.ts), which already owns shared header concerns. Both adapters depend on the seam and both need the rule, so it has two current consumers rather than a speculative one. It returns the trimmed value or a reason (`empty`, `illegalCharacters`).
Both adapters also need the identical "refuse a stored credential" diagnosis, differing only by package prefix. `LlmError` is declared in the seam's `index.ts`, so `assertUsableApiKey(raw, pkg, ref)` lives there beside it and neither adapter carries a local copy. The predicate module stays dependency-free: importing `LlmError` into `api-key.ts` would cycle with `index.ts`'s re-export of it.
The client cannot import any of this: client packages reference only client packages, so `packages/client/ui-models` mirrors the predicate in its own `apiKey.ts` and owns the localized messages, exactly as `validateDeepSeekModels` mirrors the host's `catalogModel` schema. Each side names the other in a comment.
### What each surface does
| Surface | Behavior |
|---|---|
| `dsh-llm` | Owns `normalizeApiKey`, `assertUsableApiKey`, and `INVALID_CREDENTIAL_CODE`, which is deliberately outside `DEFAULT_RETRYABLE_CODES`. |
| `llm-deepseek` `resolveAdapterOptions` | Refuses a literal `apiKey` no header can carry, beside the other beyond-schema bounds; uses the trimmed value. An absent or blank one falls through to `apiKeyEnv`. |
| `llm-deepseek` `resolveApiKey` | Normalizes what the credentials seam or environment returns, rejecting with `INVALID_CREDENTIAL` naming the Models page and never echoing the key. |
| `llm-pi-ai` `resolveProfiles` | Applies the shared rule, keeping its "omit it to use ambient authentication" wording, and writes the trimmed value into the resolved profile. |
| `llm-pi-ai` `resolveApiKey` | Normalizes the credential and environment paths. A profile naming no credential still returns `undefined`, so ambient and OAuth routes are unaffected. |
| `llm-pi-ai` `discoverModels` | Normalizes before building the header, so an illegal key is a credential fault rather than an unreachable endpoint. A probe carrying no key stays unauthenticated. |
| `ui-models` | Mirrors the charset rule, adds the shape heuristic, trims `keyDraft` before probe and `credentials.set`, and fixes the `stringAt` emptiness test. A blank field remains a no-op that submits; a field holding only whitespace is a field-level failure. Submit **and the endpoint interrogation** are both gated, so a refused key never spends a round trip to be told what the field already says, and the failure renders on the field, matching the existing `modelFailure` pattern. |
`ProviderEditor` serves both the DeepSeek and pi-ai layouts, so one client change covers both providers. `CustomProviderCard` carries the same judgement for a hand-declared route.
`credentials-local` is deliberately untouched. It stores credentials generally, and printable-ASCII is a constraint of HTTP headers rather than of credential storage; its existing refusal of values no dotenv style can represent stands as it was.
## Alternatives considered
**A `.pattern()` on the `apiKey` schema field.** Vendored schemastery supports it, and the pattern would serialize to the browser with the rest of the namespace schema — one rule, delivered rather than mirrored. It lost because a pattern cannot trim first: `cordis.yml` would then reject a padded key while `.env` tolerated one, and the resolver would disagree with the schema about the same string. Validating in `resolveAdapterOptions` keeps every surface trim-then-validate, and that function is already where this package re-judges bounds the schema cannot express.
**A validation module shared by client and host.** Rejected by the source-plane layout: client packages reference only client packages plus `vendor/cordis` and `support/invariants`, and widening that to reach a host package would collide the two `Context` merges the split exists to keep apart. Mirroring a one-line predicate with a test on each side is the established shape here.
**A per-adapter thrower in each of `llm-deepseek` and `llm-pi-ai`.** The first plan gave each adapter its own, differing only by the package prefix in the message, with a duplication-gate exemption to excuse the pair. Rejected before implementation: `LlmError` is declared in the seam, so the seam can own the diagnosis outright, and an exemption there would have hidden exactly the duplication it was covering for.
**Sniffing the `TypeError` in the adapter's `catch`.** This would classify the ByteString failure after the fact, leaving the header construction itself unguarded. It depends on the wording of a Node error message, so it degrades silently across runtime versions, and it cannot help `llm-pi-ai`, whose request header is built inside the pi-ai SDK. Refusing the key before handing it over works for both adapters and for the discovery probe.
**Enforcing in `credentials-local.set`.** It would catch every writer at once, including a hand-edited file. It lost because that provider stores credentials of every kind, and a rule derived from HTTP header encoding does not belong to it.
**Running the shape heuristic in the resolvers too.** Symmetric, and it would stop a pasted environment line written directly into `.env`. Rejected for the lockout described above: a false positive in a resolver leaves the user no working path, while a false positive in the browser leaves the environment open.
**Probing the provider at save time to prove the key works.** It would close the complaint the sources actually open with — a save that reports success and fails at the first turn. Rejected as out of scope and, on the code as it stood, unbuildable: `discoverModels` short-circuits to the installed catalog before any network call for exactly the providers pi-ai ships catalogs for, so it verified nothing about the key, and the DeepSeek card has no probe at all. A verifier's value is distinguishing "key rejected" from "cannot reach", which is the distinction this change makes reliable; building it first would have produced a verifier unable to tell its own outcomes apart. Comparable products also do not verify on save, so a blocking network call there would be an unexpected behavior rather than a missing one.
## Consequences
A malformed key is refused at the field that holds it, and a malformed stored key fails as `INVALID_CREDENTIAL` with a message naming where to fix it and no fragment of the key. Because that code sits outside `DEFAULT_RETRYABLE_CODES`, a deterministic credential fault is no longer retried three times as a transport blip. `llm-pi-ai` discovery reports an illegal probe key as a credential fault instead of an unreachable endpoint.
The shape heuristic can refuse a real key. The first draft matched any upper-case identifier followed by `=`, which review showed was broader than intended: an all-upper-case base64 key ending in padding (`ABCD==`) matched an assignment it does not resemble. Requiring a non-`=` character after the separator excludes padding, since base64 only ever pads at the end. What remains — an upper-case name, one `=`, then a value — is a shape no known provider issues, and the rule runs only in the browser, so a user who still hits it can set the credential through the environment. The residual cost is a confusing refusal for a key nobody has yet reported.
Restricting to printable ASCII is stricter than the transport requires: a header value may carry `\x80``\xFF`. Admitting latin-1 would let `é` through to return an opaque 401 instead of a local, explained refusal, so the stricter rule is deliberate. A provider that issues latin-1 keys would need this rule widened.
The charset predicate exists twice, once per source plane. The layout forbids sharing it; each side carries its own test and names its twin.
Keys already stored by an earlier build are read through `resolveApiKey`, so an illegal stored value fails at resolution rather than at request time. The diagnosis improves, but the failure moves earlier for anyone currently holding one.
The costliest way to get this wrong would have been to treat absence as invalidity: a rule applied to `undefined` breaks every route authenticating through ambient discovery or OAuth, and a blank field that blocked submit makes editing any other setting demand re-entering the key. Both are pinned by tests rather than left to care.
## Testing
`packages/llm/llm/tests/api-key.spec.ts` drives `normalizeApiKey` and `assertUsableApiKey` over the whole input table — empty, whitespace-only, padded, interior-space, C0 control, emoji, CJK, full-width, latin-1, and the printable-ASCII boundary — and pins that a refusal carries `INVALID_CREDENTIAL` and no part of the key.
`packages/llm/llm-deepseek/tests/` covers the literal-config path in `adapter.spec.ts` and the stored-credential path end to end in `dynamic-config.spec.ts`, through the real credentials seam rather than a stub. `packages/llm/llm-pi-ai/tests/` covers `resolveProfiles` — including that the trimmed value reaches the resolved profile, which the `...rest` spread would otherwise discard — and the discovery probe, including that a probe with no key sends no `authorization` header.
`packages/client/ui-models/tests/` pins `apiKeyFailure` over the same table plus the paste-shape cases, and drives both cards: a blank field submits without writing a credential, a whitespace-only field fails on the field, an illegal or wrapped key blocks submit and the interrogation alike, a padded key is trimmed before `credentials.set` and before an interrogation, and a hand-declared route can be created with no key at all.
The user-visible terminal state is pinned where it is actually assembled: `examples/headless-agent/tests/headless.snapshot.ts` runs the one-shot app against a stored key no header can carry, over the same keyless composition its missing-credential sibling uses, and records that the turn ends on `INVALID_CREDENTIAL` with an actionable message carrying neither the key nor the word `ByteString`. A package test could not have shown that, and the web e2e covers only the browser half.

# Agent Note: 在 API Key 进入 HTTP header 之前校验其格式
Status: implemented
[English](2026-08-06-api-key-format-validation.md) | 中文
## Problem
一个含有 HTTP header value 无法承载的字符的 API Key曾被每一层配置界面接受直到构造请求时才失败——离引发它的那个字段已经很远。
把含 emoji、中文或全角标点的 Key 粘进 Web 模型设置页,保存会报成功。第一轮对话随即失败于 `Cannot convert argument to a ByteString because the character at index 7 has a value of 55357 which is greater than 255`——其中的下标与码点是 UTF-16 内部细节,不附带任何可执行动作,却泄露了 Key 中某一个字符的码点。`llm-deepseek` 之所以产出这句,是因为 `fetch` 在 [adapter.ts](../../../../packages/llm/llm-deepseek/src/adapter.ts) 的 `try` 内部构造 `Bearer` header而那个 `catch` 把一切失败都标为 `TRANSPORT`;该标签又在 `DEFAULT_RETRYABLE_CODES` 之中,于是一个永久且确定的故障还会被重试三次。
同样的输入在 `llm-pi-ai` 上更糟。它的探测路径在 [discovery.ts](../../../../packages/llm/llm-pi-ai/src/discovery.ts) 里用裸 `fetch` 构造同一个 header并把一切失败包装成 `could not reach <url>`,于是一个本地的 Key 故障被报成网络不可达。这条探测在保存之前就够得着:`ProviderEditor` 把用户输入的 `keyDraft` 直接放进探测请求,所以「获取模型列表」按钮会在任何东西落盘之前就把非法 Key 发出去。
空白字符能通过每一道检查。`ProviderEditor` 判的是 `keyDraft.length``resolveAdapterOptions` 判的是 `config.apiKey.length`,于是三个空格构成的 Key 会被存下,随后以 `Bearer` 加若干空格去认证。`llm-pi-ai``resolveProfiles` 中拒绝空的字面量 `apiKey`,却对来自凭据或环境的 Key 完全不做检查——而那正是模型设置页写入的路径,也就是用户真正走的路径。
来源deepseek-harness#1594#1595dsh-external#247#249#266#210
## Decision
一条规则定义什么是合法 Key**trim 之后非空,且每个字符都落在 `[\x21-\x7E]`**——可打印 ASCII不含空格。
这一个断言覆盖了来源列出的全部输入空值、首尾空白、中间空白、C0 控制字符、emoji、中文、全角标点。它同时正是造成 ByteString 失败的那条约束,所以两个 issue 收敛于同一个定义,而不是两个恰好相关的修复。
第二条更窄的规则用于识别整行粘贴的环境变量:匹配 `^[A-Z][A-Z0-9_]*=[^=]` 或首尾成对引号的输入会被拒绝。把前缀限定为全大写可以让真实 Key 与之绝缘——`sk-` 这类形态会在连字符处中断标识符匹配——而要求分隔符之后必须是非 `=` 字符,则让 base64 的 padding 也与之绝缘。它报出的是与非法字符相同的那条格式失败,而不是自己的一句:读到它的人下一步动作完全一样,因此单列一句只会点出一个原因,却不改变该怎么做。
### 不变量属于每一层,启发式属于人所在的那一层
字符集规则是不变量。非 ASCII 字符对任何 provider 都**不可能**在 header value 中传输,因此在浏览器、在各个 resolver、在每一次凭据读取上执行它是结构上的一致而非约定上的一致。
形状规则是对人如何粘贴的猜测,因此**只在浏览器中运行**。`llm-pi-ai` 前面挂着 OpenAI、Anthropic 以及任意手工声明的网关,本仓库并不掌握它们的 Key 格式;若这条规则运行在 resolver 中,一个签发形如 `TENANT1=abc` 的网关会让用户被彻底锁死、无路可走——设置页拒绝它,手写的 `.env` 在读取时同样被拒。把启发式限制在粘贴动作发生的那一层,环境变量便始终是那条出路。
### 「没有 Key」是一种配置状态不是缺失
在这里,「没有 API Key」意味着三件完全不同的事其中只有一件是错误。规则作用于**已提供**的值;至于究竟有没有提供,由各个调用方自行判断。
**未指定。** 既不写 `apiKey` 也不写 `apiKeyEnv` 的 profile是由 harness 所持有的 Key 之外的东西来鉴权的。[provider.ts](../../../../packages/llm/llm-pi-ai/src/provider.ts) 中的 `routeAuth` 保留内置 catalog provider 自身的鉴权,正是为了让 provider 原生的 ambient 发现得以存活;而该 catalog 附带的 `openai-codex` 通过 OAuth 鉴权,并会直接拒绝一个显式的 Key。`namesCredential` 承载着这一区分。在 `llm-deepseek` 中,缺省的 `apiKey` 同样会回落到 `apiKeyEnv`。未指定的情形永不参与校验。
**Web UI 中留空的输入框。** 即便某个 provider 的 Key 已经存好,该输入框也是空着打开的——`keyStored` 的文案写的是「已配置——输入新值以替换」——所以留空意味着*保持已存储的值*。`ProviderEditor` 在草稿为空时完全跳过 `credentials.set`,这一点保持不变:留空绝不拦截提交,否则改一个 base URL 都得重新输一遍 Key。
**已提供,但为空或纯空白。** 它意味着什么,取决于「缺失」在该界面上选中了什么,而两个适配器的差异是有依据的。在 `llm-pi-ai` 中它是错误,因为那里的缺失切换的是**鉴权方式**——转向内置 provider 的 ambient 发现或 OAuth——因此一个空 Key 究竟想选哪一种是真有歧义;它的措辞指明了合法替代路径而非单纯拒绝(*has an empty apiKey; omit it to use ambient authentication*)。在 `llm-deepseek` 中,缺失只是为同一把 Key 选择了另一个**来源** `apiKeyEnv`,因此空白字面量会像缺省一样经该回落解析。在浏览器中它始终是失败,两张卡片皆然:字段是人刚刚敲过字的地方,静默丢弃他敲进去的内容永远不是正确答案。
因此 `normalizeApiKey` 接受 `string`,而绝非 `string | undefined`
### 规则住在哪里
`normalizeApiKey``dsh-llm` seam 的一个模块,与已经承担共享 header 事务的 [attribution.ts](../../../../packages/llm/llm/src/attribution.ts) 并列。两个适配器都依赖该 seam 且都需要这条规则,因此它拥有两个当前消费者而非一个预设消费者。它返回 trim 后的值,或一个原因(`empty``illegalCharacters`)。
两个适配器同样都需要那句完全相同的「拒绝一个已存储凭据」的诊断,差别仅在包名前缀。`LlmError` 声明在 seam 的 `index.ts` 中,因此 `assertUsableApiKey(raw, pkg, ref)` 就住在它旁边,两个适配器都不再各留一份。断言模块本身保持零依赖:把 `LlmError` 引入 `api-key.ts` 会与 `index.ts` 对它的再导出成环。
客户端无法引入其中任何一个client 包只 reference client 包,因此 `packages/client/ui-models` 在自己的 `apiKey.ts` 中镜像这个断言并持有本地化文案,正如 `validateDeepSeekModels` 镜像 host 侧的 `catalogModel` schema。两侧在注释中互相指名。
### 各个界面各做什么
| 界面 | 行为 |
|---|---|
| `dsh-llm` | 拥有 `normalizeApiKey``assertUsableApiKey``INVALID_CREDENTIAL_CODE`,后者刻意不进 `DEFAULT_RETRYABLE_CODES`。 |
| `llm-deepseek` `resolveAdapterOptions` | 拒绝标头无法承载的字面量 `apiKey`,与其他超出 schema 的边界检查并排;使用 trim 后的值。缺省或空白的 `apiKey` 回落到 `apiKeyEnv`。 |
| `llm-deepseek` `resolveApiKey` | 归一化凭据 seam 或环境返回的值,以 `INVALID_CREDENTIAL` 拒绝,消息指明模型设置页,绝不回显 Key。 |
| `llm-pi-ai` `resolveProfiles` | 施加这条共享规则保留其「omit it to use ambient authentication」的措辞并把 trim 后的值写进解析后的 profile。 |
| `llm-pi-ai` `resolveApiKey` | 归一化凭据与环境路径。不指定任何凭据的 profile 仍返回 `undefined`ambient 与 OAuth 路由不受影响。 |
| `llm-pi-ai` `discoverModels` | 在构造 header 之前归一化,使非法 Key 成为凭据故障而非端点不可达。不带 Key 的探测保持未鉴权。 |
| `ui-models` | 镜像字符集规则,加入形状启发式,在探测与 `credentials.set` 之前 trim `keyDraft`,并修正 `stringAt` 的空值判断。留空的输入框仍是可以提交的空操作;只含空白的输入框则是字段级失败。提交**与端点探测**同时受拦截,因此被拒绝的密钥不会白花一次往返去换取字段上已经写明的答案;失败呈现在字段上,与既有的 `modelFailure` 模式一致。 |
`ProviderEditor` 同时服务 DeepSeek 与 pi-ai 两种布局,因此一处客户端改动覆盖两个 provider。`CustomProviderCard` 为手工声明的路由承载同一套判定。
`credentials-local` 刻意不动。它存储各类凭据,而可打印 ASCII 是 HTTP header 的约束而非凭据存储的约束;它既有的、拒绝任何 dotenv 样式都无法表示的值的行为保持原样。
## Alternatives considered
**在 `apiKey` schema 字段上加 `.pattern()`。** vendor 中的 schemastery 支持它,且该 pattern 会随命名空间 schema 一同序列化到浏览器——一条规则,投递而非镜像。它落败于 pattern 无法先行 trim那样 `cordis.yml` 会拒绝带首尾空白的 Key 而 `.env` 却容忍resolver 与 schema 会对同一个字符串给出分歧。在 `resolveAdapterOptions` 中校验可以让每一层都是 trim-then-validate而该函数本就是本包重新裁定 schema 无法表达的边界之处。
**由 client 与 host 共享一个校验模块。** 被 source plane 布局否决client 包只 reference client 包外加 `vendor/cordis``support/invariants`,把它放宽到够得着 host 包会撞上这一分割本就要隔开的两份 `Context` 合并。在两侧各镜像一行断言并各配一份测试,是此处的既定形态。
**在 `llm-deepseek` 与 `llm-pi-ai` 中各留一个抛错 helper。** 最初的计划正是各留一份,差别仅在消息中的包名前缀,并配一个重复检测豁免来放行这一对。在实现之前即被否决:`LlmError` 声明在 seam 中,因此 seam 完全可以自己拥有这句诊断,而那里的一个豁免恰恰会掩盖它本要遮掩的重复。
**在适配器的 `catch` 中嗅探 `TypeError`。** 这只是事后归类 ByteString 失败header 构造本身仍无防护。它依赖 Node 错误消息的措辞,因而会随运行时版本静默失效;它也帮不到 `llm-pi-ai`——后者的请求 header 构造在 pi-ai SDK 内部。在交出 Key 之前就拒绝,则对两个适配器与探测路径同时有效。
**在 `credentials-local.set` 中执行。** 它能一次性拦住所有写入方,包括手工编辑的文件。它落败于该 provider 存储各种类型的凭据,而一条源自 HTTP header 编码的规则并不属于它。
**让形状启发式也在 resolver 中运行。** 更对称,且能拦住直接写进 `.env` 的整行环境变量。因上文所述的锁死风险而否决resolver 中的一次误判会让用户无路可走,浏览器中的一次误判则仍留有环境变量这条路。
**在保存时探测 provider 以证明 Key 可用。** 它能关掉来源真正开篇抱怨的那件事——保存报成功、第一轮才失败。因超出范围而否决,且在当时的代码上无法建成:对 pi-ai 恰好自带 catalog 的那些 provider`discoverModels` 会在任何网络调用之前短路到内置 catalog因而对 Key 什么都验证不了;而 DeepSeek 卡片根本没有探测。验证器的价值在于分清「Key 被拒」与「无法连通」,而这正是本次改动让其变得可靠的区分;先建验证器只会得到一个分不清自身结果的验证器。同类产品也不在保存时验证,因此保存时的阻断式网络调用会是一个意外行为,而非一处缺失。
## Consequences
格式错误的 Key 在持有它的那个字段上就被拒绝;格式错误的已存储 Key 以 `INVALID_CREDENTIAL` 失败,消息指明修复位置且不含 Key 的任何片段。由于该 code 位于 `DEFAULT_RETRYABLE_CODES` 之外,一个确定性的凭据故障不再被当作瞬时传输抖动重试三次。`llm-pi-ai` 的探测把非法 Key 报为凭据故障,而非端点不可达。
形状启发式可能拒绝一个真实的 Key。最初的写法匹配任意「全大写标识符接 `=`」,评审指出其覆盖面比预期更宽:一个以 padding 结尾的全大写 base64 Key`ABCD==`)会命中它并不像的赋值形态。要求分隔符之后必须是非 `=` 字符即可排除 padding——base64 的 padding 只出现在末尾。剩下的形态(大写名称、一个 `=`、然后是值)是已知 provider 不会签发的,且该规则只在浏览器中运行,因此仍撞上它的用户可通过环境变量设置该凭据。残留代价是对一个尚无人报告过的 Key 给出一次令人困惑的拒绝。
限定为可打印 ASCII 比传输本身的要求更严header value 是可以承载 `\x80``\xFF` 的。放行 latin-1 会让 `é` 通过并换回一个语焉不详的 401而不是一次本地的、有解释的拒绝因此从严是刻意的。若某个 provider 签发 latin-1 的 Key这条规则需要放宽。
字符集断言存在两份,每个 source plane 一份。布局禁止共享它;两侧各自带测试并在注释中指名其孪生体。
早先版本已存下的 Key 会经 `resolveApiKey` 读取,因此一个非法的既存值将从解析时开始失败,而非到请求时才失败。诊断变好了,但对当前正持有这类值的人而言,失败点提前了。
把这件事做错的最大代价,会是把「未指定」当成「非法」:一条施加到 `undefined` 上的规则会打断每一条依赖 ambient 发现或 OAuth 鉴权的路由,而一个会拦截提交的空输入框,则会让改动任何其他设置都必须重新输入 Key。这两点都由测试钉住而不是仅仰赖谨慎。
## Testing
`packages/llm/llm/tests/api-key.spec.ts` 以整张输入表驱动 `normalizeApiKey``assertUsableApiKey`——空值、纯空白、带首尾空白、含中间空格、C0 控制字符、emoji、中文、全角、latin-1以及可打印 ASCII 的边界字符——并钉住一次拒绝携带 `INVALID_CREDENTIAL` 且不含 Key 的任何部分。
`packages/llm/llm-deepseek/tests/``adapter.spec.ts` 中覆盖字面量配置路径,在 `dynamic-config.spec.ts` 中经真实凭据 seam而非 stub端到端覆盖已存储凭据路径。`packages/llm/llm-pi-ai/tests/` 覆盖 `resolveProfiles`——包括 trim 后的值确实到达解析后的 profile否则会被 `...rest` 展开丢弃——以及探测路径,包括不带 Key 的探测不会发出 `authorization` 标头。
`packages/client/ui-models/tests/` 以同一张表加上形状用例钉住 `apiKeyFailure`,并驱动两张卡片:留空的输入框可提交且不写入凭据、只含空白的输入框在字段上失败、非法或被包裹的 Key 同时拦截提交与探测、带首尾空白的 Key 在 `credentials.set` 与探测之前被 trim以及手工声明的路由可以完全不带 Key 创建。
用户可见的终态则钉在它真正被组装的位置:`examples/headless-agent/tests/headless.snapshot.ts` 让 one-shot 应用在一个 HTTP 标头无法承载的已存密钥下运行,复用其 missing-credential 兄弟场景的同一套无密钥 composition并记录该轮以 `INVALID_CREDENTIAL` 结束、消息可操作且既不含密钥也不含 `ByteString` 字样。包级测试无法证明这一点,而 web e2e 只覆盖了浏览器那一半。

English | [中文](2026-08-06-provider-credential-lifecycle.zh.md)
## Problem
The Models editor spans independent settings and credential RPC domains. It previously committed provider settings before storing the API key but kept the revision and original subtree from when the card opened. If the credential write failed, retry replayed the already-committed settings mutation with a stale revision and produced a conflict, leaving the user unable to complete the second stage from the same card. A blank pi-ai key also wrote the derived `apiKeyEnv` without a credential, which prevented pi-ai from using provider-native discovery. At deletion, the inverse leak remained: the profile disappeared but its page-stored key stayed in `.env` and silently became active when the provider was added again. Generic row actions and confirmation copy did not identify which provider would be changed.
## Decision
Provider save remains a two-stage settings-then-credentials operation over the existing wire domains, but the card treats the successful settings response as a commit checkpoint. It replaces its comparison subtree and expected revision with the returned redacted descriptor before attempting `credentials.set`; if that second stage fails, the draft key and card stay visible, and retry produces no settings ops and repeats only the credential write. Genuine concurrent changes before the first settings commit still fail with `settings-conflict`. Typed keys are trimmed at the UI and direct DeepSeek resolver boundaries, and pi-ai records a derived reference only when the normalized key is non-empty; saving a blank key materializes an empty, reference-free profile for provider-native discovery.
Deletion removes a credential only when the joined row identifies the exact `<ROUTE>_API_KEY` reference derived by this page and reports it configured and writable. It unsets that credential before the user-layer profile so a settings-stage failure leaves the row and its frozen target visible for retry; both unsets are idempotent. Custom references, environment credentials, missing credentials, and targets the join cannot identify are retained. The row's accessible Edit/Delete names and the destructive dialog title, description, and final action all use the same stable `Display Name (route-id)` identity, collapsing to the route id when both strings match. The dialog states whether the stored key will be removed and owns operation failures instead of replacing the whole page with a load-error banner. Rows expose API-key state only from the value-free join: a confirmed literal or referenced credential is a green solid dot, a confirmed missing named reference is a red solid dot, and reference-free provider-native authentication or unavailable credential enrichment has no dot. Each dot has accessible copy and a tooltip, while successful Apply uses the same provider identity in a local status message and never echoes secret material.
## Alternatives considered
**Add a cross-domain transaction RPC.** Settings and credentials have separate owning services and durable stores; introducing a new host transaction would broaden the public wire and still require compensation for provider-specific persistence failures. The UI checkpoint makes the current ordered stages recoverable without adding a fourth configuration contract.
**Delete every credential reference named by a removed profile.** A custom reference can be shared, externally managed, or intentionally survive profile churn. Exact equality with this page's derived target plus configured+writable state is the narrow evidence available to the page; anything weaker risks deleting a credential it does not own.
**Remove settings first and compensate by recreating the profile.** The browser holds only a redacted subtree and cannot faithfully reconstruct stored literal secrets or concurrent edits. Credential-first deletion leaves the authoritative profile visible on partial failure and makes retry safe without synthesizing configuration.
## Consequences
The Models page can recover from either second-stage failure without reload, secret disclosure, or a false concurrency conflict, and blank-key pi-ai profiles preserve Bedrock, Vertex, and other provider-native authentication. Confirmed status is visible without turning route liveness, native authentication, or a failed credential lookup into a false error, and a successful replacement remains observable even when the row stays green. Deleting a page-managed provider no longer leaves a reusable local key, while ambiguous credentials deliberately remain for manual management. Save and delete are still not atomic across durable stores: a process crash can stop between stages, but their order and idempotence leave an observable, retryable state. Component tests pin partial-success retries, empty-key native auth, normalized literals, status visibility, target identity, cleanup ownership, and credential/settings rejection ordering; the keyless browser scenario pins bilingual accessible copy and verifies that confirmed deletion removes both `settings.yaml` profile and `.env` credential. This decision refines the Models apply semantics recorded in the [web configuration plane note](../architecture/2026-07-30-web-config-plane.md).

# Agent Note: 可恢复的提供方凭据生命周期
Status: implemented
[English](2026-08-06-provider-credential-lifecycle.md) | 中文
## 问题
Models 编辑器横跨互相独立的 settings 与凭据 RPC 领域。之前它先提交提供方 settings再存储 API 密钥,却一直保留卡片打开时的 revision 和原始子树。如果凭据写入失败,重试会用陈旧 revision 重放已提交的 settings 变更,并产生冲突,导致用户无法从同一张卡片完成第二个阶段。空的 pi-ai 密钥还会写入派生的 `apiKeyEnv`,却不写入凭据,从而阻止 pi-ai 使用提供方原生凭据发现。删除时则存在相反的残留问题profile 消失了,页面存储的密钥却保留在 `.env` 中,并在重新添加提供方时静默地恢复作用。笼统的行操作与确认文案也没有标明要更改哪个提供方。
## 决策
提供方保存仍在现有 wire 领域上按先 settings、后凭据的两阶段顺序执行但卡片会把成功的 settings 响应视为提交检查点。它会在尝试 `credentials.set` 之前,用返回的脱敏 descriptor 替换比较基准子树与预期 revision如果第二阶段失败草稿密钥与卡片会继续显示重试不会产生 settings op只会再次写入凭据。首次 settings 提交之前发生的真实并发变更仍会以 `settings-conflict` 失败。UI 与 DeepSeek 直连 resolver 边界均会去除所输密钥的首尾空白且只有标准化密钥非空时pi-ai 才会记录派生引用;留空密钥会具化一个空的、不带引用的 profile以便使用提供方原生凭据发现。
只有当联接所得的行识别出该页面派生的精确 `<ROUTE>_API_KEY` 引用,并将其报告为已配置且可写时,删除操作才会清除该凭据。它会先取消设置该凭据,再取消设置用户层 profile如果 settings 阶段失败,该行及其已冻结的目标仍可见,便于重试。两项 unset 都具备幂等性。自定义引用、环境凭据、缺失的凭据,以及联接无法识别目标的凭据均会保留。行的无障碍 Edit/Delete 名称以及破坏性对话框的标题、说明和最终操作都使用同一个稳定的 `Display Name (route-id)` 标识;当两个字符串相同时,标识会简化为路由 id。对话框会说明是否一并删除已存密钥并在自身内显示操作失败而不是用加载错误横幅替换整个页面。行只根据不含值的联接结果展示 API 密钥状态:确认已配置的字面密钥或引用凭据显示为绿色实心点,确认缺失的具名引用显示为红色实心点,无引用的提供方原生认证或无法取得凭据补充信息时则不显示状态点。每个状态点都有无障碍文案和工具提示;「应用」成功后的本地状态消息会使用同一个提供方标识,且绝不回显任何机密内容。
## 曾考虑的替代方案
**添加跨领域事务 RPC。**settings 与凭据分属不同的主管服务与持久存储;引入新的 Host 事务会扩大公开 wire 面而且仍需要补偿提供方特定的持久化失败。UI 检查点让当前的有序阶段变得可恢复,无需添加第四项配置契约。
**删除被移除 profile 所指定的每一个凭据引用。**自定义引用可能被共享、由外部管理,或有意在 profile 反复增删时存留。与该页面派生目标精确相等,再加上已配置且可写的状态,是页面所能获得的最小范围证据;比这更弱的判定都有可能删除不属于它的凭据。
**先删除 settings再重建 profile 以作补偿。**浏览器只持有脱敏后的子树,无法忠实重建已存的字面机密或并发编辑。先删除凭据可以让权威 profile 在部分失败时仍然可见,并且无需合成配置就能安全重试。
## 后果
Models 页可以从任一第二阶段失败中恢复,无需重新加载,也不会泄露机密或产生虚假的并发冲突;空密钥的 pi-ai profile 会保留 Bedrock、Vertex 与其他提供方原生认证。已确认的状态清晰可见同时不会把路由存活状态、原生认证或凭据查询失败误报为错误即使该行继续显示绿色密钥替换成功也仍然可观察。删除由页面管理的提供方不再遗留可重用的本地密钥而存在歧义的凭据会有意保留交由手动管理。保存与删除在跨持久存储时仍非原子操作进程可能在两个阶段之间崩溃但它们的顺序与幂等性会留下可观察、可重试的状态。组件测试固定了部分成功后的重试、空密钥原生认证、标准化字面值、状态可见性、目标标识、清理所有权以及凭据settings 拒绝顺序;无密钥的浏览器场景固定了双语无障碍文案,并验证确认删除会同时清除 `settings.yaml` profile 与 `.env` 凭据。此决策细化了 [web 配置平面 note](../architecture/2026-07-30-web-config-plane.md) 中记录的 Models 应用语义。

# Agent Note: Reader scroll attribution through the observed-top ledger
Status: implemented
English | [中文](2026-08-06-reader-scroll-attribution-observed-top-ledger.zh.md)
## Problem
ChatView's bottom-follow recognized only wheel/trackpad gestures as reader input: while pinned to the floor, a scroll event without matching wheel movement was treated as programmatic and snapped back. Touch panning, native-scrollbar dragging, and keyboard paging therefore could not leave the bottom of a streaming transcript — on a phone the tail was effectively locked. That wheel-only provenance was a deliberate deferral in the [sticky-composer note](2026-07-29-sticky-composer-conversation-scroll.md), which rejected a general input state machine "for this narrow fix" and left every other scroll source outside the model.
## Decision
Reader input is no longer identified by device. ChatView keeps an observed-top ledger (`observedTopRef`): the last `scrollTop` either delivered on the main thread or written by the component, recorded synchronously at every programmatic write site — bottom follow, open restore, prepend anchoring, resize follow, and scroll delivery itself. When a scroll event arrives, a position that deviates from `min(ledger, floor)` by more than half a pixel is reader input; a position on the ledger (a delayed programmatic delivery) or exactly on the shrunken floor (a browser clamp after content shrank) preserves the current ownership state. Ownership then changes only through reader input under the existing threshold rule: within `FOLLOW_THRESHOLD` of the floor re-pins, beyond it releases follow and shows Back to bottom. The wheel listener and its epoch bookkeeping are deleted; the component listens to `scroll` alone, so wheel, touch, scrollbar, keyboard, and any future input source are covered by one rule.
## Contract change: coalesced shrink-plus-regrow clamps
A shrink clamp whose layout regrows within the same rendering update before the clamp's scroll event is delivered is geometrically indistinguishable from reader input, so it now reads as the reader and releases follow (Back to bottom recovers). Realistic React-commit-driven shrink and regrow is still absorbed: the layout-effect follow re-pins and re-records the ledger per commit, and a shrink-only clamp lands exactly on `min(ledger, floor)`. Only a non-React reflow that shrinks and regrows inside one update mis-attributes. The previous wheel model kept following in that raced case; the unit contract was rewritten to the absorbed-shrink-only guarantee in the same change.
## Testing
Unit specs in `packages/client/ui-conversation/tests/chat-view.spec.tsx` pin the ledger contract directly: a `readerScroll` helper delivers a position the component never wrote, programmatic deliveries land on the ledger, and the stream-finalization shrink clamp keeps following. Two scenarios in `apps/web/tests/chat-scroll-contract.e2e.ts` extend the [browser e2e lane](../testing/2026-07-24-web-gui-browser-e2e-lane.md): keyboard paging over a settled transcript and a touch-style momentum fling against paced streaming, both red under the wheel-only implementation and green under the ledger.
The lane's Chromium cannot synthesize any non-wheel device scrolling, which bounds what the e2e can drive for real: `Input.synthesizeScrollGesture` with a touch source and hand-rolled `Input.dispatchTouchEvent` sequences deliver DOM events but never move a scroller (headless and headed-under-Xvfb alike); the `default` gesture source synthesizes wheel events; and compositor scrollbars ignore synthetic mouse input entirely, with a gutter visible only when `--hide-scrollbars` is removed. Keyboard is the one working non-wheel primitive, so it carries the real-input-pipeline proof, and the fling scenario replays touch's signature — per-frame decaying displacements the component never authored — through the scrollport directly.
## Alternatives considered
**Keep the wheel-only model.** Rejected: it is the defect. Touch, scrollbar, and keyboard readers cannot take ownership away from a streaming tail, and each newly supported device would need its own carve-out.
**Enumerate input devices.** Adding `touchstart`/`pointerdown`/`keydown` listeners beside the wheel epoch was the obvious extension. Rejected: native-scrollbar dragging exposes no input event to latch before its scrolls arrive, device lists rot as browsers add sources, and every listener would need its own compositor-delivery grace window — the input state machine the sticky-composer note already declined to build.
**Absorb the coalesced shrink-plus-regrow clamp with heuristics.** Floor-mismatch grace windows or deferred rAF re-checks could keep the raced clamp from reading as the reader. Rejected: streaming rewrites the floor at chunk pace (24 ms) against ~16 ms frames, so any grace window either swallows genuine touch input during streaming — reopening the bug this change fixes — or is too short to cover the race it targets. The mis-attribution is accepted and recoverable instead.
**Drive real touch and scrollbar devices in e2e.** Rejected by the environment, not by preference: every synthesis path (CDP touch gestures, touch event sequences, synthetic mouse on classic scrollbars, headed under Xvfb) was probed and cannot scroll; the details live in Testing above.
## Consequences
Every reader input owns bottom-follow uniformly, with less code: the wheel listener, its epoch counter, and the pre-input baseline bookkeeping are gone, and attribution rides state the component already maintained. The sticky-composer note's layout, wheel chaining, and prepend-anchoring decisions are untouched and remain authoritative; its narrow provenance rule is superseded by this note. The cost is the contract change above — a coalesced non-React shrink-plus-regrow clamp now pauses follow until the reader returns to the floor or presses Back to bottom — traded for touch, scrollbar, and keyboard correctness during streaming. The e2e lane gains non-wheel coverage only within what its browser can synthesize; if gesture synthesis starts working in a future Chromium, the fling emulation can be replaced by real touch strokes without changing the asserted contract.

# Agent Note: 经由 observed-top ledger 的读者滚动归因
Status: implemented
[English](2026-08-06-reader-scroll-attribution-observed-top-ledger.md) | 中文
## 问题
ChatView 的贴底跟随此前只把滚轮触控板手势识别为读者输入钉在底部floor期间一个没有对应滚轮位移的滚动事件会被视为程序化滚动并被拉回底部。因此触控平移、拖动原生滚动条与键盘翻页都无法离开流式 transcript文本记录的底部在手机上尾部实际上被锁死。这种仅认滚轮的输入来源判定是 [sticky-composer 笔记](2026-07-29-sticky-composer-conversation-scroll.md)中有意的暂缓:该笔记拒绝为「此次窄范围修复」建立通用输入状态机,把其余所有滚动来源都留在模型之外。
## 决策
读者输入不再依据设备来识别。ChatView 维护一份 observed-top ledger`observedTopRef`):即最近一次由主线程交付、或由组件自身写入的 `scrollTop`,并在每一个程序化写入点(贴底跟随、打开时恢复、前置锚定、尺寸变化跟随以及滚动交付本身)同步记录。滚动事件到达时,偏离 `min(ledger, floor)` 超过半像素的位置即为读者输入;落在 ledger 上的位置(迟到的程序化交付),或恰好落在收缩后底部上的位置(内容收缩后的浏览器钳制),则维持当前的所有权状态。此后所有权只经由读者输入、按既有阈值规则变化:位置距底部在 `FOLLOW_THRESHOLD` 以内则重新贴底,超出则释放跟随并显示「回到底部」。滚轮监听器及其 epoch 簿记已删除;组件只监听 `scroll`,因此滚轮、触控、滚动条、键盘以及未来任何输入来源都由同一条规则覆盖。
## 契约变更:收缩与重新增长被合并的钳制
如果一次收缩钳制的布局在同一次渲染更新内、赶在该钳制的滚动事件交付之前重新增长,那么这个事件在几何上与读者输入无法区分,因此它现在会被判读为读者并释放跟随(可经「回到底部」恢复)。现实中由 React 提交commit驱动的收缩与重新增长仍会被吸收layout effect 中的跟随会在每次提交后重新贴底并重新记录 ledger而仅收缩的钳制会恰好落在 `min(ledger, floor)` 上。只有在同一次更新内先收缩再重新增长的非 React 重排会被误归因。旧的滚轮模型在这种竞态情形下会保持跟随;单元测试契约已在同一变更中改写为只吸收纯收缩的保证。
## 测试
`packages/client/ui-conversation/tests/chat-view.spec.tsx` 中的单元测试直接钉住 ledger 契约:`readerScroll` 辅助函数交付一个组件从未写入过的位置,程序化交付落在 ledger 上,流收尾阶段的收缩钳制保持跟随。`apps/web/tests/chat-scroll-contract.e2e.ts` 中的两个场景扩展了[浏览器 e2e 车道](../testing/2026-07-24-web-gui-browser-e2e-lane.md):在已停稳的 transcript 上做键盘翻页以及对着按节奏推进的流式输出做一次触控式惯性快滑momentum fling两者在仅认滚轮的实现下均为红、在 ledger 下均为绿。
该车道的 Chromium 无法合成任何非滚轮的设备滚动,这限定了 e2e 能真实驱动的范围:触控来源的 `Input.synthesizeScrollGesture` 与手工构造的 `Input.dispatchTouchEvent` 序列都能交付 DOM 事件,却从不移动滚动容器(无头模式与 Xvfb 下的有头模式皆然);`default` 手势来源合成的是滚轮事件;合成器滚动条则完全无视合成的鼠标输入,且只有移除 `--hide-scrollbars` 后才能看到滚动条槽。键盘是唯一可用的非滚轮原语,因此由它承担真实输入流水线的证明;快滑场景则把触控的特征(组件从未写入过的逐帧衰减位移)直接回放进滚动容器。
## 曾考虑的替代方案
**保留仅认滚轮的模型。** 否决:它本身就是缺陷所在。触控、滚动条与键盘读者无法从流式尾部夺走所有权,而每种新支持的设备都需要单独开一个特例。
**逐一枚举输入设备。** 在滚轮 epoch 旁边加挂 `touchstart`/`pointerdown`/`keydown` 监听器是最显而易见的扩展。否决:拖动原生滚动条在其滚动事件到达之前不暴露任何可供锁存的输入事件;设备清单会随浏览器新增输入来源而逐渐腐化;而且每个监听器都需要自己的合成器交付宽限窗口——这正是 sticky-composer 笔记当初就拒绝构建的那个输入状态机。
**用启发式吸收收缩与重新增长被合并的钳制。** 针对底部失配的宽限窗口,或推迟到 rAF 的复查本可让这种竞态下的钳制不被判读为读者。否决流式输出以分片节奏24 ms改写底部而帧间隔约 16 ms因此任何宽限窗口要么会在流式输出期间吞掉真实的触控输入重新打开本次变更所修复的缺陷要么短到盖不住它想针对的竞态。转而接受这一误归因它是可恢复的。
**在 e2e 中驱动真实的触控与滚动条设备。** 否决来自环境而非偏好取舍每条合成路径CDP 触控手势、触控事件序列、经典滚动条上的合成鼠标、Xvfb 下的有头模式)都逐一试过,均无法滚动;细节见上文「测试」一节。
## 后果
每种读者输入现在都以同一方式拥有贴底跟随,而代码更少:滚轮监听器、它的 epoch 计数器以及输入前基线簿记均已移除归因搭载在组件本就维护的状态之上。sticky-composer 笔记中的布局、滚轮链式处理与前置锚定决策原样保留,仍为权威;其窄范围的输入来源规则由本笔记取代。代价就是上文的契约变更:一次收缩与重新增长被合并的非 React 钳制现在会暂停跟随直到读者回到底部或按下「回到底部」以此换来流式输出期间触控、滚动条与键盘的正确性。e2e 车道获得的非滚轮覆盖仅限其浏览器能够合成的范围;若手势合成在未来某个 Chromium 版本中开始可用,可以在不改变所断言契约的前提下,把快滑模拟替换为真实的触控划动。

**Sub-call contexts are deferred through the parent.** Injecting inside `run_code` would break parent call/result adjacency, so `ToolRunContext.deferContext()` collects every sub-result `additionalContexts` entry in dispatch order. The registry carries that array even when the program later throws, and the loop appends each entry only after the outer result and every sibling result in the step. An outer post-execute block discards tool-deferred entries and exposes only contexts explicitly attached by the blocking decision.
**Concurrency is serialized.** Each run owns a dispatch queue, so even `Promise.all` executes tool calls in submission order. Settlement abandons queued calls that have not started. Parallelism requires per-tool concurrency-safety metadata.
**Concurrency is bounded, not serialized.** Each run owns a dispatch queue that starts calls strictly in submission order and classifies each one through `registry.executionMode`, the same fail-closed `isConcurrencySafe` contract the native loop uses. Consecutive parallel-classified calls overlap up to `maxParallelSubCalls` (default 10; `1` restores serial dispatch); an exclusive call drains the pool and runs alone.

This is not a `terminal` card: that card's semantics are "a shell command in a working directory", which a program is not.

Both flavors state the same contract in their own primitive: independent read-only calls MAY overlap under `Promise.all` (TypeScript) or `asyncio.gather` (Python), mutating calls run alone in submission order, and dependent work sequences with `await`. The declaration prefix can be as large as native schemas, especially in `'both'`, but remains stable for provider caching.
## Consequences
Deployments switching to `'code'` must update any native-only `toolOrder`. Assembly listeners own the integrity of any rewritten protocol surface. Sub-dispatch remains serialized, while per-call contexts retain their source, envelope, and metadata through the outer result.

**Result elision / summarization over native tool-calling.** Addresses only the context-bloat half of the problem: trimming old `tool-result`s is cheap to add as a logged surface replacement under reconstructable requests, but still pays one model round-trip per call and cannot express loops, branches, or joins. Complementary, not competing; it can layer under Code Mode for residual native calls.
**Parallel native dispatch in the loop.** The other answer to round-trip cost; still valid future work (the open TODO), still blocked on concurrency-safety metadata, and still no composition — it parallelizes calls the model already decided on in one step. Code Mode's serialized-queue decision keeps the two compatible: when the metadata lands, both native parallel dispatch and per-tool binding parallelism unlock together.
**Parallel native dispatch in the loop.** The other answer to round-trip cost at decision time; it was blocked on concurrency-safety metadata and offers no composition either way — it parallelizes calls the model already decided on in one step. Code Mode's queue decision kept the two compatible, and that is how it played out: the metadata landed as `isConcurrencySafe` (the [parallel tool-call note](2026-07-10-parallel-tool-call-execution.md)), and native rolling-pool dispatch and per-tool binding parallelism unlocked on the same classifier.
**Always-exclusive (Cloudflare-faithful, no mode).** Rejected for this SDK's primary consumer: a coding agent's bread-and-butter single calls (`bash`, `read`, `edit`) are already ideal as native calls, and forcing every edit through a program taxes the common case. The mode config keeps the faithful form (`'code'`) one line away without imposing it.

**Large lossless JSON values can exhaust memory.** Tool bindings snapshot lossless JSON before dispatch and return canonical JSON resolutions whole. The runtime validates both sides of the worker port and applies no per-binding byte cap; structured-clone cost and process or worker memory are the practical bounds. The combined outer-output ledger for logs, the completion value, and a failure diagnostic is the only byte-capped boundary.
**Serialized-only sub-dispatch.** `Promise.all` gains no wall-clock parallelism yet, only fewer round-trips; models may over-expect. The instructions state it; lifting it is tied to the same concurrency-safety metadata the native parallel-dispatch TODO needs.
**Sub-dispatch overlap is bounded by tool safety claims, not by the caller.** A program's `Promise.all` or `asyncio.gather` buys wall-clock parallelism only across calls the tool itself classifies concurrency-safe; a run of exclusive calls still costs its round-trips in sequence, and models may over-expect. Both flavors' SDK instructions state the real contract. This note shipped the serialized placeholder that made the risk absolute; the [live-parallel Agent Note](2026-07-26-code-mode-live-parallel-dispatch.md) owns the scheduler and its overlap cap.
**Budget metering reads the event loop, not a flag.** Busy-time polling (`eventLoopUtilization()`) is coarser than an exact CPU meter — a budget expires up to one poll interval late — and its correctness claim ("a pending dispatch cannot pause it") is load-bearing against a hostile program. Both sides are unit-tested (hot loop with a pending decoy dispatch dies at `computeMs`; idle-on-slow-binding survives to `maxWallMs`), and the poll interval is an internal constant, not config — nothing a deployment could mis-tune into a bypass. `maxWallMs` is config, and it reaches `setTimeout`, which clamps a delay above `MAX_TIMER_DELAY_MS` (2^31-1 ms) to 1 ms; a positivity check alone therefore accepts a 25-day ceiling that expires on the first tick and times out every run. The worker runtime range-checks the field at load for that reason. `computeMs` needs no upper bound because it is compared against measured utilization instead of being handed to a timer.

# Agent Note: `/feedback` command
Status: implemented
English | [中文](2026-07-28-feedback-command.zh.md)
## Problem
A user who notices something wrong mid-session has nowhere to put that observation. Telling the model wastes a turn, changes the conversation the user was having, and buries the remark in derived history where no later reader can find it. Writing it outside the session loses the context that makes it meaningful — which session, at which point, against which work.
The capture surface has to be usable at the moment of annoyance, which rules out anything requiring the user to leave the interactive client, and it must not perturb the run in progress: no model tokens, no turn of work, no change to the request the user is waiting on.
## Decision
`@deepseek-ai/dsh-command-feedback` in `packages/feedback/command-feedback/` registers one global `feedback` command over `ctx.commands`. `/feedback <text>` acknowledges; bare or whitespace-only input returns a direct usage error. The handler is synchronous, injects only `commands`, and has no configuration.
The package declares the log-only `feedback/record { text }` session event and exports `recordFeedback(session, text)` as its command-independent producer. The producer discards surrounding whitespace, rejects an empty result, and appends exactly one event. `/feedback` delegates to it, so another UI, hook, or host integration can record the same domain fact without constructing a slash command.
`dsh-commands` still writes its `command/run` / `command/done` lifecycle pair around `/feedback`, but this command sets `recordInput: false`. Its `command/run` therefore carries the command identity and source without `args`; the feedback text exists only in `feedback/record`, while `command/done` carries the acknowledgement outcome. All three records are log-only and non-surface. Their appends start persistence's ordinary eager drain; nothing forces a flush, so acknowledgement reports that the feedback is in the log rather than already on disk.
Capture remains inert for the running agent and model. The optional OTel telemetry package later adds one infrastructure consumer: it observes `feedback/record` as a release trigger in `FEEDBACK_ONLY` mode and as the local-only warning trigger in `DISABLED` mode, without changing the feedback event or command path. See [Feedback-gated session telemetry](2026-08-05-feedback-gated-session-telemetry.md).
### Why feedback owns an event
Feedback is a domain fact, while `/feedback` is one trigger. Keeping the only payload in `feedback/record` lets later triggers use the same event and lets consumers select feedback without depending on command names or parsing command lifecycle records. Omitting `command/run.args` for this definition avoids two authoritative-looking copies of one human remark.
### Why the model never sees it
Feedback is about the session, not input to it. Injecting it as a user message would change the next model request, contradicting the requirement that recording not perturb the run, and would make the remark part of the conversation it comments on. `command/run` and `command/done` are absent from `SurfaceEventType`, so they cannot acquire a `surfaceOp` or enter derived history even by mistake.
### Verbatim text
Surrounding whitespace is discarded, but nothing else is parsed. `/feedback /plan felt slow` records `/plan felt slow`; the leading `/plan` is content, not a nested command. Control-word grammar of the kind `/goal` uses would make the corresponding literal feedback impossible to express, which is the opposite of what a capture surface is for.
### A new group
`packages/feedback/` is a new group because no existing one owns this. `goal/` is objective state, `session-title/` is titles, `core/` is the product spine. The group holds one producer package; cross-cutting consumers stay in their owning groups rather than forcing this one to grow.
## Alternatives considered
**Use `command/run` as the feedback record.** Rejected because feedback would then be coupled to one trigger and consumers would have to identify a domain fact by command name. A non-command producer could not create the same record without pretending to execute a command.
**Store the text in both `feedback/record` and `command/run.args`.** Rejected because one act would have two payload copies with no useful distinction. `recordInput: false` preserves the generic lifecycle while leaving the domain event authoritative.
**Inject feedback as a user message via `agent.inject()`.** Needs no new event type and reuses the path `/goal` mutations take. Rejected: it makes the feedback model-visible, so it enters the next request, changes the run being commented on, and consumes tokens — contradicting all three parts of the no-perturbation requirement.
**Make `/feedback` a true no-op that records nothing.** The most literal reading of "does not do anything". Rejected because it makes the command pointless: the stated requirement was that the remark reach the session log.
**Register the command inside an existing package** such as `packages/ui/commands`. Avoids a new group and its README pair. Rejected: `ctx.commands` is the registry, not a home for arbitrary command implementations, and the requester asked for a standalone package.
**Parse structure out of the text** (category prefixes, severity markers). Rejected as speculative: no consumer needs that structure, and any control-word grammar makes the corresponding literal feedback unrecordable. Verbatim text is the widest surface a future consumer can narrow; a parsed one cannot be widened after the fact.
**Add a model-facing tool instead of a slash command.** Rejected: feedback is a direct human observation. Routing it through the model spends a turn, lets the model paraphrase the user's words, and makes the record contingent on the model choosing to call the tool.
## Consequences
The shipped `dsh` base mounts the command unconditionally — no configuration, no dependency on the goal stack. The Web client exposes it through its command adapter. Headless mode, ACP, and JSON-RPC do not provide a command adapter, so `/feedback` is unavailable there.
The package owns one independent append-only event with no cross-event or mutable-data relation for an invariant companion to check. The event follows the session log's existing replay, fork, persistence, and crash-tail behavior.
Deferred: no product or model consumer; no structured fields; no amend or withdraw, since the log is append-only and this package adds no tombstone; and no explicit durability barrier, so an entry recorded immediately before a crash can be lost with any other unflushed tail. The optional telemetry consumer treats the event only as an export-policy trigger.
No keyless transcript snapshot accompanies this change, at the requester's explicit direction. Package tests, a real Loader composition test over a `cordis.yml`, and the shipped Web composition test cover registration, capture, model exclusion, and product assembly.

# Agent Note: `/feedback` 命令
Status: implemented
[English](2026-07-28-feedback-command.md) | 中文
## 问题
用户在会话中途发现问题时,没有地方记下这个观察。告诉模型会浪费一个轮次、改变用户原本进行的对话,并把这条评论埋进派生历史,使后续读者无法找到它。写到会话之外则会丢失让它有意义的上下文:属于哪个会话、处于哪个时点、针对哪项工作。
采集接口必须能在用户产生不满的那一刻使用,因此任何需要用户离开交互式客户端的方案都不可行;它还不能扰动正在进行的运行:不消耗模型 token、不产生工作轮次、不改变用户正在等待的请求。
## 决策
位于 `packages/feedback/command-feedback/``@deepseek-ai/dsh-command-feedback` 通过 `ctx.commands` 注册一个全局 `feedback` 命令。`/feedback <text>` 给出确认;空输入或仅含空白的输入返回直接用法错误。处理器是同步的,只注入 `commands`,且没有任何配置。
本包package声明仅写入日志的 `feedback/record { text }` 会话事件,并导出 `recordFeedback(session, text)`,作为不依赖命令的生产方。该生产方丢弃前后空白,拒绝空结果,并且恰好追加一个事件。`/feedback` 委托给它,因此其他 UI、钩子或 host 集成无需构造斜杠命令也能记录同一个领域事实。
`dsh-commands` 仍会围绕 `/feedback` 写入 `command/run` / `command/done` 生命周期配对,但该命令设置了 `recordInput: false`。因此,它的 `command/run` 携带命令标识与来源,但不携带 `args`;反馈文本只存在于 `feedback/record` 中,而 `command/done` 携带确认结果。三个记录都仅写入日志且非 surface。它们的追加会启动持久化的常规即时排空没有任何环节强制 flush因此确认文本报告的是反馈已进入日志而非已经落盘。
采集对正在运行的 agent 与模型仍不产生后续动作。可选的 OTel 遥测包后续增加了一个基础设施消费方:它在 `FEEDBACK_ONLY` 模式下将 `feedback/record` 作为释放触发器,在 `DISABLED` 模式下将其作为本地警告触发器,且不改变反馈事件或命令路径。见[反馈门控的会话遥测](2026-08-05-feedback-gated-session-telemetry.md)。
### 为何反馈拥有自己的事件
反馈是领域事实,而 `/feedback` 是一种触发方式。只把载荷保存在 `feedback/record` 中,既让后续触发方式可以使用同一个事件,也让消费方无需依赖命令名或解析命令生命周期记录即可筛选反馈。在该定义中省略 `command/run.args`,可避免同一条人类评价出现两个看起来都具有权威性的副本。
### 为何模型永不看到它
反馈是关于会话的,而不是会话的输入。将其作为 user 消息注入会改变下一次模型请求,与「记录不得扰动运行」的要求相冲突,也会让该评论成为它所评论的那段对话的一部分。`command/run``command/done` 不属于 `SurfaceEventType`,因此即便出错也无法获得 `surfaceOp` 或进入派生历史。
### 原样文本
前后空白会被丢弃,但除此之外不做解析。`/feedback /plan felt slow` 记录 `/plan felt slow`;开头的 `/plan` 是内容,而非嵌套命令。若采用 `/goal` 那样的控制词语法,对应的字面反馈将无法表达,这与采集接口的目的正好相反。
### 一个新的分组
`packages/feedback/` 是新分组,因为现有分组都不拥有此职责:`goal/` 负责目标状态,`session-title/` 负责标题,`core/` 是产品主干。该分组只包含一个生产方包;跨领域的消费方留在各自所属的分组,而不是迫使这个包不断膨胀。
## 考虑过的替代方案
**使用 `command/run` 作为反馈记录。** 已否决,因为这会将反馈与一种触发方式耦合,消费方还必须通过命令名识别领域事实。非命令生产方若不伪装成执行命令,就无法创建相同记录。
**同时在 `feedback/record` 与 `command/run.args` 中存储文本。** 已否决,因为同一行为会产生两个没有实质区别的载荷副本。`recordInput: false` 保留通用生命周期,同时让领域事件保持权威性。
**通过 `agent.inject()` 将反馈作为 user 消息注入。** 无需新增事件类型,并复用 `/goal` 变更所走的路径。已否决:它会让反馈对模型可见,从而进入下一次请求、改变正被评论的那次运行并消耗 token——与「不得扰动」要求的三个方面全部冲突。
**让 `/feedback` 成为真正的空操作,什么都不记录。** 这是对「什么都不做」最字面的理解。已否决:这会使命令失去意义——明确的要求是让这条评论进入会话日志。
**在现有包中注册该命令**,例如 `packages/ui/commands`。可省去新分组及其双语 README。已否决`ctx.commands` 是注册表,而不是任意命令实现的归属地;且请求者明确要求独立的包。
**从文本中解析结构**(类别前缀、严重程度标记)。已否决,属于投机设计:没有消费方需要该结构,而任何控制词语法都会让对应的字面反馈无法记录。原样文本是未来消费方可以收窄的最宽接口;而已被解析的接口无法事后放宽。
**改为提供面向模型的工具。** 已否决:反馈是人类的直接观察。经由模型会消耗一个轮次、让模型改写用户的原话,并使记录取决于模型是否选择调用该工具。
## 后果
随附的 `dsh` 基础组合无条件挂载该命令:没有配置,也不依赖 goal 栈。Web 客户端通过命令适配器暴露该命令。无头模式、ACP 和 JSON-RPC 不提供命令适配器,因此 `/feedback` 在那里不可用。
本包拥有一个独立的仅追加事件不存在跨事件关系或可变数据关系可供不变式伴生插件检查。该事件遵循会话日志现有的回放、fork、持久化和崩溃尾部行为。
延期事项:没有产品或模型消费方;没有结构化字段;不支持修改或撤回,因为日志仅追加且本包不新增 tombstone且没有显式持久化屏障因此紧临崩溃前记录的条目可能与其他未 flush 的尾部一同丢失。可选的遥测消费方只将该事件作为导出策略触发器。
本次变更按请求者的明确指示不附带无密钥 transcript文本记录快照。包测试、基于真实 `cordis.yml` 的 Loader 组合测试,以及随附的 Web 组合测试覆盖注册、采集、模型排除和产品组装。

# Agent Note: Code Mode language dispatch and the Python SDK renderer
Status: implemented
English | [中文](2026-07-31-code-mode-language-dispatch.zh.md)
## Problem
Code Mode generated one SDK flavor: TypeScript. `ToolRegistry` hard-coded `renderToolsSdk` for the `tools:sdk` section and `requireCodeRuntime` rejected any `ctx.codeRuntime.language !== 'typescript'`. Adding a CPython backend means a program's source language is no longer fixed: the same visible tool registry must project a Python SDK when a Python runtime is loaded, and the model-facing `run_code` schema strings ("Execute a Python program …") must match the SDK section's language so the model never sees a TypeScript instruction over a Python runtime.
This is the tool-facing half of the multi-language Code Mode split; the [code-runtime seam](../../../../packages/code-runtime/code-runtime/README.md) already carries `CodeRuntime.language`. This note owns only how `dsh-tools` dispatches on that field. The backend that implements `language: 'python'` is owned by its own note, delivered separately.
## Decision
Language selection is a lookup on `ctx.codeRuntime.language`, resolved lazily at prompt assembly, against two parallel tables in `dsh-tools`:
- `SDK_RENDERERS` (index.ts) maps a language to its `tools:sdk` renderer — `typescript → renderToolsSdk`, `python → renderToolsSdkPy`. The `tools:sdk` section reads the loaded runtime's language and picks the renderer; `requireCodeRuntime` rejects a `mode: code`/`both` runtime whose language is absent from the table, naming the known languages.
- `RUN_CODE_FLAVORS` (code-mode.ts) maps a language to its two model-facing `run_code` strings (tool `description` and the `code` parameter description), so a language's SDK section and its transport schema always agree.
Both tables are read with `Object.hasOwn` before use so a language named `toString`/`constructor` cannot resolve an inherited `Object.prototype` member as a renderer. The two guards differ in reachability: `SDK_RENDERERS`' in-callback guard is unreachable because `requireCodeRuntime` validated the same `const` table earlier in the same callback (it carries a `/* v8 ignore */`), while `RUN_CODE_FLAVORS`' guard is the primary, publicly reachable rejection — any language absent from the flavor table hits it through `run_code`'s language-aware getters, which the public `schemas()` reaches without passing `requireCodeRuntime` first; the test reads one of those getters off the definition directly, under a language absent from both tables. A language present in `SDK_RENDERERS` but not `RUN_CODE_FLAVORS` is drift the shared `CodeSdkLanguage` `satisfies` pins reject at `typecheck`, so it is not an input either guard can see; what the guards still own is a mounted runtime reporting a language absent from both tables. Schema emission reads the runtime through `peekRuntime()` rather than `requireRuntime()`: `undefined` (no runtime mounted, reached by definition readers and `schemas()`, of which the doc-catalog harvest is the only shipped one and none of which feeds a model because assembly passes `requireCodeRuntime` first) degrades to the TypeScript flavor, whereas a mounted unknown language fails loud — this is NOT the silent fallback rejected below, which concerns emitting a wrong-language SDK for a real runtime. Adding a backend language is three parallel edits — a `CodeSdkLanguage` member and the two table entries — plus its renderer and the prose that names the well-known values instead of deriving them (the seam's `dsh-code-runtime` README pair, its `CodeRuntime.language` JSDoc, and the `docs/core-data-structures/code-runtime.md` pair; this package's own README pair and its `Config.mode` JSDoc — no gate checks any of it), with no `agent-loop` or registry-structure change.
`code-mode.ts` depends only on the runtime seam (`@deepseek-ai/dsh-code-runtime`), never on a concrete backend; dispatch is by `runtime.language` at run time. The tool layer therefore lands independently of the protocol and backend PRs — it needs only the seam's `language` field, which is already on master.
### The Python SDK renderer
`py-types.ts` renders the same unified tool-schema vocabulary `jsonSchemaToTs` covers, targeting Python: `jsonSchemaToPy` emits a type expression per JSON-schema node, and `renderToolsSdkPy` assembles named `TypedDict`s for each visible tool's arguments and canonical output plus a `tools` object with usage instructions equivalent to the TypeScript flavor. Unsupported raw constructs degrade rather than throwing during assembly, matching the TypeScript renderer's contract. The output is deterministic — lexicographic tool order, byte-identical text for an unchanged tool set — so the prompt stays prefix-cache-friendly. Lexicographic means one ordered member stream: a tool whose name is not a legal attribute is listed as a `tools[name]` comment in its sorted position rather than partitioned to the end, matching how the TypeScript flavor quotes an exotic key in place. That stream forces one thing directly — comment lines are not statements, so a tool set that emits no method at all still needs an explicit `pass`. Three further rules are Python-specific rather than consequences of the ordering. The usage contract states that the declarations are static stubs and arguments are plain `dict`/`list` values: a `TypedDict` reads as a constructible class, so a model that writes `FooArgs(field=1)` gets a `NameError` — TypeScript's `interface` is visibly a type, and the TS flavor's "runs type-stripped" clause already covers it. A description becomes the method's docstring emitted as the FIRST statement of its body: above the `async def` the first one would document the `Tools` class and the rest would be dead expressions, leaving every method undocumented. And a `list[…]` chain degrades to `Any` past `MAX_LIST_NESTING`, because CPython's tokenizer rejects a line with more than 200 open brackets and the block must stay parseable Python — the same reason `docLines` escapes quotes and backslashes. `ts-types` needs neither: TypeScript attaches a leading `/** … */` to the member that follows it and bounds nesting nowhere in its grammar.
The standard that cap serves is grammatical validity, and the boundary is deliberate: a long `A | B | …` union is valid Python at any length and is left uncapped, even though CPython's `compile()` exhausts its C recursion walking the left-nested `BinOp` spine (measured on 3.9: 1,000 branches compile, 5,000 raise `RecursionError`). Nothing compiles this block — it is prompt text — so that limit costs nothing, whereas capping union length would retire the deep-chain tests that pin the walk's linear time and the class-name propagation cap. A future renderer that does need compilable output should flatten unions rather than truncate them.
`renderType` validates the whole schema once (`assertSupportedJsonSchema`) and then trusts it, wrapping the walk in one `try/catch` that degrades to `Any` — the same trusted-after-validation stance the sibling `ts-types` renderer takes at this typed same-process seam ([Trust TypeScript at typed same-process seams](../../../../AGENTS.md)). It deliberately carries NO defenses against a schema whose accessors mutate between reads (post-validation cycles, TOCTOU on `const`/`enum`, self-referential functions): the input is a first-party registration (a `defineTool` literal or a raw registration) or a wire-derived plain JSON schema — the former is trusted per AGENTS.md, the latter is a `JSON.parse` product that physically cannot carry accessors, and `renderType` re-validates the whole tree on every call regardless — so such inputs are unreachable, and adding per-shape guards here would break symmetry with `ts-types` (which has none) for values the static interface forbids. `jsonSchemaToPy(schema: unknown)` accepts `unknown` and returns `Any` on a malformed schema — the Python counterpart of the TS flavor's `unknown` — but its contract is "degrade an unsupported schema", not "survive an adversarial mutating one".
## Alternatives considered
- **A `language` config field on `ToolRegistry`.** Deployment would then have two places to name the language (the loaded runtime and the tools config) that can disagree; the loaded runtime is the single source of truth, so the registry reads it rather than duplicating it.
- **Importing the Python backend into `code-mode.ts` to detect it.** That would couple the tool layer to a concrete backend and force the protocol/backend PRs to land first. Runtime dispatch on `language` keeps the layer backend-agnostic and independently shippable.
- **A default renderer for an unknown language.** A silent fallback would emit a TypeScript SDK over, e.g., a Ruby runtime — the model would see instructions in the wrong language. Failing loud at assembly is the repository's misconfiguration stance.
## Consequences
Adding a backend language is three parallel edits — a `CodeSdkLanguage` member, an `SDK_RENDERERS` entry, and a `RUN_CODE_FLAVORS` entry — plus the renderer function the second points at, with no change to `agent-loop` or the registry structure. The two tables (`SDK_RENDERERS`, `RUN_CODE_FLAVORS`) must stay in step, and that invariant is checked statically rather than left to review: both are `satisfies`-checked against that one union, so a language added to one and not the other fails `typecheck`. This is the mechanical form the drift risk deserves — the runtime `Object.hasOwn` guards would catch it too, but only once a backend reporting that language ships: one PR after the drift, at the consumer's integration point rather than where it was introduced, and on this base never, since no second backend exists. The tables keep their `Record<string, …>` declared type because `CodeRuntime.language` is an unconstrained `string`; the union pins what the harness ships, the guards reject what a runtime reports. What stays outside that check is the prose that names the well-known values instead of deriving them: `dsh-code-runtime`'s README pair, its `CodeRuntime.language` JSDoc, and the `docs/core-data-structures/code-runtime.md` pair at the seam, plus this package's own README pair and its `Config.mode` JSDoc. Earlier notes name the values as the state at their own PR and are not on that list. Two separate reasons keep it ungated. Prose is not type-checked at all, wherever the union lives. And no type-level pin can stand in for it here: the interface package must not import its consumer's table, and `CodeRuntime.language` stays an unconstrained `string` by design, so moving the union into the seam would not apply it either. A unit test pinning the two key sets equal was rejected in favor of this: it would buy the same check at the cost of a test-only export of two private tables, and would run later than the compiler does. Which of the two runtime failures surfaces depends on the entry point, for a language absent from both tables: assembly reports the missing renderer, because `wireSchemas` calls `requireCodeRuntime` before projecting, while the public `schemas()` reaches `run_code`'s language-aware getters first and reports the missing flavor. The tool layer stays free of any concrete backend dependency, so it lands and is testable on master ahead of the Python protocol and backend.
The cost is that the Python branch of both tables is unreachable on this base: `CodeRuntime.language` is set by the loaded backend, the only published backend is `dsh-code-runtime-worker` (`'typescript'`), and the registry reads the loaded runtime rather than a config field, so no assembled application can select `renderToolsSdkPy` or `PYTHON_FLAVOR`. The model-visible surface is therefore unchanged by this note's work until a backend reporting `'python'` is published, and this PR's coverage is unit-level — the renderer output plus the dispatch and rejection paths. The keyless snapshot for the Python model interface belongs to the PR that publishes that backend, because only there does a real `cordis.yml` over published plugins produce a Python assembly; a snapshot example that mounted a fixture runtime here would assert against a test double, which [docs/testing.md](../../../../docs/testing.md) rejects as a substitute for the assembled application transcript.
Two runtime contracts the Python SDK text asserts are owed by that same backend PR. First, the instructions tell the model that exactly `tools` and `ToolCallError` are bound and that the declared `TypedDict` classes are not, so the backend must inject those two names — with `ToolCallError.toolName` populated per the seam's `errorClass` contract — and must NOT bind the declared class names into the program's globals; injecting them "helpfully" would make the SDK text false. Second, the language has to be bound to the request: `requireCodeRuntime` resolves `ctx.codeRuntime` separately at assembly and at `run_code` execution, so a reload that swapped the runtime between those two points would hand a program written against one flavor to the other. The split is finer than those two points — `run_code`'s `description` and `parameters` getters each call `resolveFlavor(peekRuntime())`, and `schemaOf` destructures both, so one projection reads the runtime twice; both reads are for `run_code`'s own schema, since the getters are installed on that one definition and every other definition carries plain data properties. A reload between those two reads yields a single schema whose two halves name different languages. Neither is reachable here — one published backend means both reads return the same flavor and no program ever runs against this renderer's output — and the cross-language rejection is not testable until a second language exists.
Third, that PR owns the CPython floor, and with it the renderer's Unicode-table skew. Four expressions read the running engine's tables (Node 22.23.1: Unicode 17.0) while the interpreter uses its own (CPython 3.9.6: 13.0.0): `isBareIdentifier`'s `IDENTIFIER`, and `camelCase`'s split set, head test, and `toUpperCase()`. An interpreter older than the engine is the failing direction — the engine emits a character its tokenizer refuses, taking the whole block down — and it arrives by three independent paths. Through the predicate, a bare method or field name carrying a character added between the two versions — to `XID_Start` at its head, or to `XID_Continue` in any tail position, the middle of a name included. Through `camelCase`'s XID reads, a class name, which reaches emitted text whenever any object shape in the tool's schema declares a `TypedDict`, and which the predicate's verdict on the tool name does not gate: `zz-` plus U+1E4D0 never reaches the predicate's skew, since the `-` rejects it outright, yet it still declares `class Zz𞓐xArgs`. Through the case mapping, a class name derived from a tool the predicate accepted — a different table and a wider window than XID membership: U+019B is XID_Start and NFKC-stable, so `async def ƛ` compiles on 3.9.6, but Node uppercases it to U+A7DC (unassigned there; CPython's own `.upper()` is the identity) and `class ꟜArgs` fails with `invalid non-printable character U+A7DC`. The exposure window is the characters and mappings that changed between the two versions, so the PR that names a supported CPython range must decide explicitly between accepting it and pinning all four read points to tables for that floor — pinning the predicate alone leaves both class-name paths open. Nothing here can decide it: the floor does not exist yet, and a table pinned to a guess would be a deployment-varying constant with no configurability behind it. A second axis rides along with the floor and is not one of the four: the names and syntax the block would evaluate at definition time. `TypedDict` needs 3.8, the PEP 585 builtin generics `dict[str, Any]` and `list[…]` need 3.9, an `A | B` annotation 3.10, and `NotRequired` 3.11. These are not parse failures — the block parses on any version, which is the standard the `MAX_LIST_NESTING` cap serves — but definition-time evaluation failures, and nothing in the product evaluates this text. Recording them with the read points keeps "parseable on the supported range" from being read as "executable on it".

# Agent Note: Code Mode 语言分发与 Python SDK 渲染器
Status: implemented
[English](2026-07-31-code-mode-language-dispatch.md) | 中文
## 问题
Code Mode 只生成一种 SDK 形态TypeScript。`ToolRegistry``tools:sdk` 段硬编码了 `renderToolsSdk`,且 `requireCodeRuntime` 会拒绝任何 `ctx.codeRuntime.language !== 'typescript'`。引入 CPython 后端后,程序的源语言不再固定:同一个可见工具注册表在加载 Python 运行时时必须投射出 Python SDK而面向模型的 `run_code` schema 字符串("Execute a Python program …")也必须与 SDK 段的语言一致,模型才不会在 Python 运行时下看到 TypeScript 指令。
这是多语言 Code Mode 拆分中面向工具的那一半;[代码运行时 seam](../../../../packages/code-runtime/code-runtime/README.md) 已经携带 `CodeRuntime.language`。本 Note 只负责 `dsh-tools` 如何在该字段上分发。实现 `language: 'python'` 的后端由它自己的 Note 负责,单独交付。
## 决策
语言选择就是对 `ctx.codeRuntime.language` 的查表,在 prompt 装配时惰性解析,查 `dsh-tools` 里两张平行的表:
- `SDK_RENDERERS`index.ts把语言映射到它的 `tools:sdk` 渲染器——`typescript → renderToolsSdk``python → renderToolsSdkPy``tools:sdk` 段读取所加载运行时的语言并选出渲染器;`requireCodeRuntime` 拒绝其语言不在表中的 `mode: code`/`both` 运行时,并列出已知语言。
- `RUN_CODE_FLAVORS`code-mode.ts把语言映射到它那两条面向模型的 `run_code` 字符串(工具 `description``code` 参数描述),使一种语言的 SDK 段与它的传输 schema 始终一致。
两张表在使用前都以 `Object.hasOwn` 读取,这样名为 `toString`/`constructor` 的语言不会把继承自 `Object.prototype` 的成员解析成渲染器。两个守卫的可达性不同:`SDK_RENDERERS` 的段内守卫不可达,因为 `requireCodeRuntime` 已在同一回调更早处校验过同一张 `const` 表(它带 `/* v8 ignore */`);而 `RUN_CODE_FLAVORS` 的守卫是主要的、可公开到达的拒绝路径——任何缺席 flavor 表的语言都经 `run_code` 的语言感知 getter 到达它,而公共 `schemas()` 抵达那些 getter 时并未先过 `requireCodeRuntime`;测试直读 definition 上的其中一个 getter用的是对两张表都缺席的语言。「在 `SDK_RENDERERS` 里却不在 `RUN_CODE_FLAVORS` 里」这种漂移已由共享的 `CodeSdkLanguage` `satisfies``typecheck` 处拒绝两个守卫都看不到这种输入它们如今负责的是所挂载运行时报告了一门两张表都缺席的语言。schema 发射通过 `peekRuntime()` 而非 `requireRuntime()` 读取运行时:`undefined`(无运行时,由直读 definition 的读者与 `schemas()` 到达,其中 doc-catalog 采集是唯一已交付的一个,而它们都不会喂给模型,因为组装路径先过 `requireCodeRuntime`)降级到 TypeScript flavor而挂载了未知语言则 fail loud——这不是下方被否决的静默回退那指的是为真实运行时发出错误语言的 SDK。新增一门后端语言是三处并列编辑——一个 `CodeSdkLanguage` 成员加两条表项——再加它的渲染器以及点名已知值而非从中派生的散文seam 侧的 `dsh-code-runtime` README 双语对、它的 `CodeRuntime.language` JSDoc 与 `docs/core-data-structures/code-runtime.md` 双语对;本包自己的 README 双语对与它的 `Config.mode` JSDoc无任何 gate 检查其中任何一处),不动 `agent-loop`,也不动注册表结构。
`code-mode.ts` 只依赖运行时 seam`@deepseek-ai/dsh-code-runtime`),绝不依赖具体后端;分发在运行时按 `runtime.language` 进行。因此工具层独立于协议和后端 PR 落地——它只需要 seam 的 `language` 字段,而该字段已在 master 上。
### Python SDK 渲染器
`py-types.ts` 渲染 `jsonSchemaToTs` 所覆盖的同一套统一工具 schema 词汇,目标为 Python`jsonSchemaToPy` 为每个 JSON-schema 节点发出一个类型表达式,`renderToolsSdkPy` 为每个可见工具的参数与规范输出装配具名 `TypedDict`,再加一个带用法说明的 `tools` 对象,与 TypeScript 形态等价。不支持的原始构造在装配时降级而非抛错,与 TypeScript 渲染器的契约一致。输出是确定性的——工具按字典序排列,工具集不变时文本逐字节相同——因此 prompt 保持 prefix-cache 友好。字典序意味着单一有序的成员流:名字不是合法属性的工具以 `tools[name]` 注释出现在它排序后的位置上,而不是被分拣到末尾,与 TypeScript 形态就地为异常键加引号的做法一致。这个成员流直接决定了一件事:注释行不是语句,所以一个不发出任何方法的工具集仍需显式 `pass`。另有三条规则并非源自排序,而是 Python 特有。其一,用法约定声明这些声明只是静态存根、参数为普通 `dict`/`list` 值:`TypedDict` 读起来像一个可构造的类,模型若写 `FooArgs(field=1)` 会得到 `NameError`——TypeScript 的 `interface` 一眼就是类型,且 TS 形态的「runs type-stripped」一句已经覆盖了它。其二描述会成为方法的 docstring且必须作为方法体的**第一条语句**发出:放在 `async def` 之上,第一条会变成 `Tools` 的类文档、其余都是无效果表达式,导致每个方法都没有文档。其三,`list[…]` 链超过 `MAX_LIST_NESTING` 后降级为 `Any`,因为 CPython 的 tokenizer 拒绝一行中超过 200 个同时未闭合的括号,而这个块必须是可解析的 Python——与 `docLines` 转义引号和反斜杠是同一个理由。`ts-types` 两者都不需要TypeScript 会把前置的 `/** … */` 附着到其后的成员上,其语法也不对嵌套设限。
该上限服务的标准是**语法合法性**,这条边界是有意划定的:长的 `A | B | …` union 在任何长度下都是合法 Python故不设上限——尽管 CPython 的 `compile()` 在沿左嵌套 `BinOp` 脊柱下降时会耗尽 C 递归(在 3.9 上实测1,000 个分支可编译5,000 个抛 `RecursionError`)。没有任何东西会编译这个块——它是提示词文本——所以那条限制在这里没有代价;而给 union 长度封顶会作废那几个钉住 walk 线性时间与类名传播上限的深链测试。将来若有渲染器确实需要可编译的输出,应当把 union 拍平,而不是截断。
`renderType` 先用 `assertSupportedJsonSchema` 整树校验一次、随后信任它,用单个 `try/catch` 把整个遍历兜住并降级为 `Any`——与姊妹渲染器 `ts-types` 在这个 typed 同进程 seam 上采取的「校验后信任」姿态一致([Trust TypeScript at typed same-process seams](../../../../AGENTS.md))。它有意不设任何针对「访问器在多次读取间变值」的防御(校验后成环、`const`/`enum` 的 TOCTOU、自引用函数输入是第一方注册`defineTool` 字面量或 raw 注册)或从 wire 桥接而来的纯 JSON——前者按 AGENTS.md 受信任,后者是 `JSON.parse` 产物、物理上不可能携带访问器,且每次调用 `renderType` 都会整树重新校验——这类输入不可达,而在此加逐形态守卫会为静态接口所禁止的值破坏与 `ts-types`(没有这类守卫)的对称。`jsonSchemaToPy(schema: unknown)` 接受 `unknown` 并对畸形 schema 返回 `Any`——TypeScript 形态 `unknown` 的对应物——但它的契约是「降级不支持的 schema」而非「扛住对抗性的可变 schema」。
## Alternatives considered
- **在 `ToolRegistry` 上加一个 `language` 配置字段。** 那样部署方就会有两处命名语言(所加载的运行时与 tools 配置)且可能相互矛盾;所加载的运行时是唯一真相来源,故注册表读取它而不复制它。
- **把 Python 后端 import 进 `code-mode.ts` 来检测它。** 那会把工具层耦合到具体后端,并迫使协议/后端 PR 先落地。按 `language` 运行时分发使该层保持后端无关、可独立发布。
- **为未知语言提供默认渲染器。** 静默回退会在比如 Ruby 运行时上发出 TypeScript SDK——模型会看到错误语言的指令。在装配处 fail loud 是本仓库对错误配置的立场。
## Consequences
新增一门后端语言是三处并列编辑——一个 `CodeSdkLanguage` 成员、一个 `SDK_RENDERERS` 表项、一个 `RUN_CODE_FLAVORS` 表项——再加第二处所指向的渲染器函数,不动 `agent-loop`,也不动注册表结构。两张表(`SDK_RENDERERS``RUN_CODE_FLAVORS`)必须同步,且这条不变式由静态检查把关,而非交给 review两张表都以 `satisfies` 对上述同一个 union 校验,因此只加其一而漏掉另一会在 `typecheck` 处失败。这正是该漂移风险应有的机械形式——运行期的 `Object.hasOwn` 守卫同样能捕获,但要等到有后端报告该语言之后:晚于漂移引入一个 PR且触发点在消费方的集成处而非漂移引入处在当前 base 上则永远不会触发,因为不存在第二个后端。两张表的声明类型仍是 `Record<string, …>`,因为 `CodeRuntime.language` 是不受约束的 `string`union 钉住本仓库交付了什么守卫拒绝运行时报告了什么。落在这条检查之外的是点名已知值而非从中派生的散文seam 侧的 `dsh-code-runtime` README 双语对、它的 `CodeRuntime.language` JSDoc 与 `docs/core-data-structures/code-runtime.md` 双语对,再加本包自己的 README 双语对与它的 `Config.mode` JSDoc。更早的 note 点名这些值时记的是其自身 PR 当时的状态,不在此列。让它无 gate 的是两条独立理由。其一散文根本不受类型检查union 放在哪里都一样。其二,类型级替代在这里也不可用:接口包不得 import 其消费方的表,而 `CodeRuntime.language` 按设计保持不受约束的 `string`,即便把 union 迁进 seam 也不会作用到它。用一个断言两张表键集相等的 unit test 的方案被否决:它买到的是同一条检查,代价却是把两张私有表做测试专用导出,且运行时机晚于编译器。对两张表都缺席的语言,两种运行期失败中报出哪一条随入口而异:组装路径报缺渲染器,因为 `wireSchemas` 在投影前先调 `requireCodeRuntime`;而公共 `schemas()` 先经过 `run_code` 的语言感知 getter报的是缺 flavor 表项。工具层不依赖任何具体后端,因此它能先于 Python 协议和后端在 master 上落地并可测。
代价是两张表的 Python 分支在当前 base 上不可达:`CodeRuntime.language` 由所加载的后端设定,已发布的后端只有 `dsh-code-runtime-worker``'typescript'`),而注册表读取的是所加载的运行时而非某个配置字段,因此没有任何一份组装好的应用能选中 `renderToolsSdkPy``PYTHON_FLAVOR`。也就是说,在报告 `'python'` 的后端发布之前,本 note 的工作不改变模型可见表面,本 PR 的覆盖因此是 unit 级——渲染器输出加分发与拒绝路径。Python 模型界面的 keyless snapshot 归属于发布该后端的那个 PR因为只有在那里一份基于已发布插件的真实 `cordis.yml` 才会产出 Python 组装;在此处挂载 fixture 运行时的快照示例断言的是测试替身,而 [docs/testing.md](../../../../docs/testing.md) 明确拒绝以此替代组装好的应用 transcript。
Python SDK 文本断言的两条运行时契约同样归属那个 backend PR。其一说明文字告诉模型运行时恰好绑定 `tools``ToolCallError` 两个名字、所声明的 `TypedDict` 类不绑定,因此后端必须注入这两个名字(并按 seam 的 `errorClass` 契约填充 `ToolCallError.toolName`),且**不得**把所声明的类名绑进程序全局——「好心」注入会使这段 SDK 文本变成假话。其二,语言必须绑定到请求上:`requireCodeRuntime` 在组装时与 `run_code` 执行时分别解析 `ctx.codeRuntime`,若在这两点之间发生重载并换掉运行时,就会把针对一种形态写成的程序交给另一种形态执行。分裂比这两点更细——`run_code``description``parameters` 两个 getter 各自调用 `resolveFlavor(peekRuntime())`,而 `schemaOf` 会解构这两个字段,因此一次投影读两次运行时;两次都属于 `run_code` 自己的 schema因为这两个 getter 只装在那一个 definition 上,其余 definition 携带的都是普通数据属性。在这两次读取之间重载会产出单个 schema 的两半分属不同语言。两者在此处都不可达——只有一个已发布后端意味着两次读取返回同一形态,且没有任何程序会针对本渲染器的输出运行——而跨语言拒绝在第二门语言存在之前也无法测试。
其三,那个 PR 拥有 CPython 版本下限,连带拥有本渲染器的 Unicode 表偏斜。有四处表达式读所运行引擎的表Node 22.23.1Unicode 17.0而解释器用它自己的表CPython 3.9.613.0.0`isBareIdentifier``IDENTIFIER`,以及 `camelCase` 的切分集、头部测试与 `toUpperCase()`。解释器旧于引擎是会失败的那个方向——引擎发出的字符被其 tokenizer 拒收,整个块随之不可解析——而它经三条独立路径抵达。经判据抵达的是裸发的方法名或字段名,其中带有一个在两个版本之间新增的字符——首位加进 `XID_Start`,或尾部任意位置(含名字中部)加进 `XID_Continue`。经 `camelCase` 的 XID 读取抵达的是类名:只要工具 schema 中有任一对象形态声明 `TypedDict`,该类名就进入发出的文本,且判据对工具名的裁决并不对它设闸——工具名 `zz-` 加 U+1E4D0 因 `-` 被判据直接拒绝、从不触及那里的偏斜,却照样声明 `class Zz𞓐xArgs`。经大写映射抵达的是由判据已接受的工具派生出的类名——这是另一张表,窗口也比 XID 归属更宽U+019B 既是 XID_Start 又 NFKC 稳定,故 `async def ƛ` 在 3.9.6 上可编译,但 Node 将其大写为 U+A7DC在那里未分配CPython 自己的 `.upper()` 在此是恒等),于是 `class ꟜArgs``invalid non-printable character U+A7DC` 失败。暴露窗口是两个版本之间发生变化的那些字符与映射,所以宣布支持某个 CPython 范围的那个 PR 必须在「接受该暴露」与「按该下限的表钉住全部四个读取点」之间显式作出决定——只钉判据会同时留下两条类名路径。此处无法决定:下限尚不存在,而按猜测钉死一张表会成为一个随部署而变、却没有可配置性支撑的常量。还有第二条轴随该下限一同确定,且不属于那四个读取点:本块在定义期会被求值的那些名字与语法。`TypedDict` 需要 3.8PEP 585 的内建泛型 `dict[str, Any]``list[…]` 需要 3.9`A | B` 形式的注解需要 3.10`NotRequired` 需要 3.11。这些不是解析失败——本块在任何版本上都能解析,这正是 `MAX_LIST_NESTING` 上限所服务的标准——而是定义期求值失败,且产品中没有任何东西会求值这段文本。把它们与那四个读取点记在一起,可避免把「在所支持范围上可解析」读成「在其上可执行」。

# Agent Note: Guarded-mutation errors append the recovery instruction at the model boundary
Status: implemented
English | [中文](2026-08-03-fs-tool-error-remedy.zh.md)
## Problem
Guarded `write` and `edit` failures reach the model with messages that state the condition but not the only correct recovery: `FS_STALE_VERSION` ("file changed since it was read") and `FS_NOT_OBSERVED` ("edit requires reading … first"). The model must guess that the recovery is a re-read (or a first read) followed by a retry, and the retry/permission/UI layers that route on the structured code see the same message text. The provider-owned messages are part of the storage seam's machine-oriented vocabulary ([filesystem capability seam](../architecture/2026-06-17-filesystem-capability-seam.md)), so the remedy cannot live there without leaking model-facing wording into every consumer of `FsError`.
## Decision
`dsh-tool-fs` owns a model-facing error wrapper, `remediateFsError` in `src/error.ts`, applied in `write.ts` and `edit.ts` after the sandbox denial mapping. It appends the recovery instruction to the two guarded-mutation codes and passes everything else through untouched:
- `FS_STALE_VERSION` (including a missing edit target, which shares the stale code) gains `— re-read the file, then retry`.
- `FS_NOT_OBSERVED` gains `— read the file, then retry`.
The structured `FsError` code is preserved so retry/permission/UI layers keep routing on it, and the original error chains as `cause`. Provider messages stay machine-oriented and unchanged.
In `edit.ts` the `fs/edit-intent` waterfall now sits inside the same `try` as the provider mutation, so the policy plugin's `FS_NOT_OBSERVED` refusal thrown from the intent slot also receives the remedy — both refusal paths reach the model with the same recovery wording.
## Alternatives considered
- **Append the remedy to the provider messages in `dsh-fs` / `dsh-fs-local`.** Rejected because those messages are machine-oriented seam vocabulary consumed by retry, permission, and UI layers as well as the model surface; model-facing wording belongs at the model boundary, where `dsh-tool-fs` already owns result formatting ([filesystem capability seam](../architecture/2026-06-17-filesystem-capability-seam.md)).
- **Add the recovery to prompt guidance instead.** Rejected because the failure arrives mid-task; a static instruction does not reliably reach the retry decision, while the error message is present exactly when the model must act.
- **Signal the remedy with a new `FsError` code.** Rejected because the two failures are the same conditions retry layers already handle; splitting the code would fork routing on identical semantics.
## Consequences
Model-visible text for the two codes changes; the `fs-policy-reject` keyless snapshot is re-recorded, and the READMEs of `dsh-tool-fs` and `dsh-fs-policy` pin the exact appended text. Unit tests cover the wrapper directly (remedy text, code preservation, cause chaining, passthrough of other codes and non-`FsError` values) and the assembled tool paths assert the remedy reaches the model for both codes.
The remedy is not a promise: a deleted observed target cannot be unblocked, because re-reading a missing file fails with `FS_NOT_FOUND` and records no observation. That dead end is pinned fail-closed in the integration tests — the retried mutation fails identically until the target exists again and is freshly observed.

# Agent Note: Guarded-mutation errors append the recovery instruction at the model boundary
Status: implemented
[English](2026-08-03-fs-tool-error-remedy.md) | 中文
## Problem
受防护的 `write``edit` 失败以只陈述条件、不给出唯一正确恢复方式的消息到达模型:`FS_STALE_VERSION`"file changed since it was read")与 `FS_NOT_OBSERVED`"edit requires reading … first")。模型必须自行猜测恢复方式是重新读取(或首次读取)后重试,而基于结构化错误码路由的重试/权限/UI 层看到的也是同一段消息文本。提供方拥有的消息属于存储接缝的面向机器词汇([filesystem capability seam](../architecture/2026-06-17-filesystem-capability-seam.md)),因此恢复指令不能放在那里,否则会把面向模型的措辞泄漏给 `FsError` 的每个消费者。
## Decision
`dsh-tool-fs` 拥有一个面向模型的错误包装 `remediateFsError`(位于 `src/error.ts`),在 `write.ts``edit.ts` 中于沙箱拒绝映射之后应用。它为两个受防护变更错误码追加恢复指令,其余错误原样透传:
- `FS_STALE_VERSION`(包括缺失的编辑目标——它与陈旧错误共用同一错误码)追加 `— re-read the file, then retry`
- `FS_NOT_OBSERVED` 追加 `— read the file, then retry`
结构化 `FsError` 错误码保持不变,使重试/权限/UI 层继续基于它路由;原始错误作为 `cause` 链入。提供方消息保持面向机器且不变。
`edit.ts` 中,`fs/edit-intent` waterfall 现在与提供方变更位于同一个 `try` 内,因此策略插件从 intent 槽抛出的 `FS_NOT_OBSERVED` 拒绝也会获得恢复指令——两条拒绝路径都以相同的恢复措辞到达模型。
## Alternatives considered
- **在 `dsh-fs` / `dsh-fs-local` 的提供方消息中追加恢复指令。** 被拒绝:这些消息是面向机器的接缝词汇,除模型表面外还被重试、权限与 UI 层消费;面向模型的措辞应位于模型边界,即 `dsh-tool-fs` 已经拥有结果格式化之处([filesystem capability seam](../architecture/2026-06-17-filesystem-capability-seam.md))。
- **改为在提示词引导中加入恢复方式。** 被拒绝:失败发生在任务中途;静态指令无法可靠地影响重试决策,而错误消息恰好在模型必须行动时出现。
- **用新的 `FsError` 错误码表达恢复指令。** 被拒绝:这两种失败本就是重试层已处理的相同条件;拆分错误码会让语义相同的路由分叉。
## Consequences
两个错误码的模型可见文本发生变化;`fs-policy-reject` 无密钥快照被重新录制,`dsh-tool-fs``dsh-fs-policy` 的 README 逐字固定追加后的文本。单元测试直接覆盖包装器恢复指令文本、错误码保留、cause 链、其他错误码与非 `FsError` 值的透传),组装后的工具路径断言两个错误码的恢复指令都到达模型。

# Agent Note: Feedback-gated session telemetry
Status: implemented
English | [中文](2026-08-05-feedback-gated-session-telemetry.zh.md)
## Problem
Session telemetry originally has one mounted behavior: every accepted record enters the reporting backend immediately. Deployments need two stricter policies without replacing the plugin: hold a session's telemetry unless its user records feedback, or disable reporting while still explaining what happens to feedback. The policy must preserve the existing full-export default and the telemetry seam's redaction-before-backend boundary.
## Decision
`@deepseek-ai/dsh-session-telemetry-otel` exposes the string-valued `TelemetryMode` enum to TypeScript callers and accepts the same three uppercase `mode` values in serialized configuration:
- `FULL` is the default and preserves immediate delivery to the configured OTel pipeline.
- `FEEDBACK_ONLY` reads the canonical session log when `feedback/record` is appended and hands over the unreleased prefix through that exact event. Records appended after that boundary remain local until another feedback event.
- `DISABLED` constructs no exporter, processor, or logger provider. A `feedback/record` listener prints that nothing is shared and the feedback remains local.
The generic telemetry coordinator owns `live` and `on-demand` capture. Live capture projects, clones, redacts, and hands each event to the backend on the session firehose. On-demand capture registers no continuous capture listeners; `captureSession(session, throughSeq)` reads the canonical log from the handoff cursor through an inclusive boundary, then projects, clones, redacts, and hands over that prefix. The cursor advances only for handed-over records. The [buffer-free replay decision](../simplification/2026-08-06-buffer-free-feedback-telemetry.md) owns why the on-demand path uses the canonical log instead of copied records.
Mode resolution is a closed, fail-before-setup check: an unknown direct-construction value fails before transport configuration is read. Only `FULL` exposes the public service's `emit()` path to the SDK pipeline. `FEEDBACK_ONLY` gives its on-demand coordinator a private backend capability; its listener passes an event to `captureSession()` only when the exact `feedback/record` object is already stored at `session.events[event.seq]`. `Session.append` commits that object before publishing `session/event`, so replay includes the feedback but cannot extend past its boundary. `DISABLED` creates neither the capability nor the SDK pipeline and does not inspect exporter configuration.
## Alternatives considered
**Open a session permanently after its first feedback.** Rejected because later work would be shared without another feedback act and the plugin would need additional open-session state. Releasing one pending prefix per feedback has the smaller state machine and the narrower sharing boundary.
**Retain capture-time redacted records until feedback.** Rejected because it duplicates an unbounded session prefix even though the canonical log already owns the events. It preserves capture-time redaction policy and operational records, but those properties do not justify the memory cost for a mode defined as uploading the session log after feedback.
**Temporarily allow public `emit()` calls during feedback replay.** Rejected because a redaction listener or another reentrant caller could enqueue an unrelated record while the flag was open. A private backend capability makes authorization structural and keeps the public service closed throughout replay.
**Use an unmounted plugin as the disabled state.** That remains the silent opt-out, but it cannot warn when feedback is recorded. The explicit disabled mode lets a deployment keep one configuration shape and communicate that the local feedback did not leave the process.
## Consequences
`FULL` remains source- and wire-compatible with the original default. `FEEDBACK_ONLY` adds no telemetry-owned per-event buffer before feedback; direct service calls and non-canonical feedback events upload nothing, and a crash before feedback uploads nothing from that prefix. Replay applies the redaction policy mounted when feedback is recorded and excludes operational records that do not exist in the canonical log. Feedback-only streams therefore carry neither `agent-error` nor `shutdown` records, and shutdown absence is not a crash signal. Each later feedback captures the suffix accumulated since the previous boundary. `DISABLED` can omit `exporter.url`, does no reporting work, and keeps feedback only in the canonical session log.

# Agent Note反馈门控的会话遥测
Status: implemented
[English](2026-08-05-feedback-gated-session-telemetry.md) | 中文
## 问题
会话遥测原本只有一种已挂载行为:每条已接受记录都立即进入上报后端。部署方需要两种更严格的策略,且不替换插件:只有用户记录反馈时才释放该会话的遥测,或禁用上报并仍向用户说明反馈的去向。该策略必须保留现有的全量导出默认值,以及遥测 seam 在记录抵达后端之前脱敏的边界。
## 决策
`@deepseek-ai/dsh-session-telemetry-otel` 向 TypeScript 调用方公开以字符串为值的 `TelemetryMode` 枚举,并在序列化配置中接受相同的三个大写 `mode` 值:
- `FULL` 是默认值,保留向已配置 OTel 流水线的即时投递。
- `FEEDBACK_ONLY` 在追加 `feedback/record` 时读取权威会话日志,并交接截至该事件的未释放前缀。该边界后追加的记录会留在本地,直到另一个反馈事件。
- `DISABLED` 不构造导出器、处理器或日志提供方。`feedback/record` 监听器会输出警告,说明什么都不会共享,且反馈仍留在本地。
通用遥测协调器拥有 `live``on-demand` 捕获。实时捕获在会话 firehose 上投影、深拷贝、脱敏每个事件,并将其交给后端。按需捕获不注册持续捕获监听器;`captureSession(session, throughSeq)` 从 handoff 游标起读取权威日志,直至含边界的指定序列号,然后投影、深拷贝、脱敏并交接该前缀。游标只为已交接记录推进。[无缓冲回放决策](../simplification/2026-08-06-buffer-free-feedback-telemetry.md)说明了按需路径为何使用权威日志而非记录副本。
模式解析采用封闭式检查,并在设置前失败:通过直接构造传入未知值时,会在读取传输配置前失败。只有 `FULL` 向 SDK 流水线开放公共服务的 `emit()` 路径。`FEEDBACK_ONLY` 向其按需协调器提供私有后端能力;其监听器向 `captureSession()` 传递事件的唯一条件,是该事件与那个 `feedback/record` 对象身份完全相同,且该对象已存储于 `session.events[event.seq]``Session.append` 在发布 `session/event` 前已提交该对象,因此回放包含该反馈,但不会越过其边界。`DISABLED` 既不创建该能力,也不创建 SDK 流水线,并且不检查导出器配置。
## 考虑过的替代方案
**会话在首次反馈后永久开放。** 已否决,因为后续工作会在用户未再次提交反馈的情况下被共享,而且插件需要额外的会话开放状态。每次反馈只释放一个待处理前缀,状态机更小,共享边界也更窄。
**反馈前保留捕获时已脱敏记录。** 已否决,因为权威日志已拥有这些事件,该方案仍会复制无上限的会话前缀。它能保留捕获时的脱敏策略与运维记录,但对于一个定义为「反馈后上传会话日志」的模式,这些性质不足以证明该内存成本合理。
**在反馈回放期间临时允许公开 `emit()` 调用。** 已否决,因为在标志开启期间,脱敏监听器或另一个可重入调用方可能将无关记录入队。私有后端能力使授权成为结构性保证,并确保公共服务在整个回放过程中保持关闭。
**以不挂载插件表示禁用状态。** 这仍然是静默退出方式,但无法在记录反馈时输出警告。显式禁用模式让部署方可以保持同一种配置形态,并说明本地反馈未离开进程。
## 后果
`FULL` 与原有默认值保持源码及协议兼容。`FEEDBACK_ONLY` 在反馈前不增加遥测自有的逐事件缓冲;直接服务调用与非权威反馈事件均不上传任何内容,且反馈前发生崩溃时,该前缀也不上传任何内容。回放使用记录反馈时挂载的脱敏策略,并排除权威日志中不存在的运维记录。因此,仅反馈的流既不携带 `agent-error` 记录,也不携带 `shutdown` 记录,而缺少 shutdown 不是崩溃信号。每个后续反馈都会捕获从上一个边界起累积的后缀。`DISABLED` 可省略 `exporter.url`,不执行任何上报工作,并仅在权威会话日志中保留反馈。

# Agent Note: Web skill tool row
Status: implemented
English | [中文](2026-08-06-web-skill-tool-row.zh.md)
## Problem
The Web transcript renders `skill` calls through the generic fallback row, so a loaded instruction set looks like an unknown tool call even though Skill is a first-class product concept. The generic row also exposes the JSON argument envelope beside the result, adding noise around the one identity users need: the loaded skill name.
## Decision
`ui-skill` registers a component under the existing `conversation.chat.toolview` keyed slot with key `skill`. The component owns its row chrome from the public `ToolRowProps` contract, matching the independent registrant posture used by the Bash sample instead of importing conversation-private components.
The collapsed row uses a 14-pixel document-and-sparkle glyph and the Bash row's neutral hierarchy: tertiary glyph, secondary `Skill` title, caption separator, and tertiary skill name. Running, failed, and interrupted calls retain the transcript's shimmer, error dot and first-line summary, and warning dot semantics. A settled call expands through the whole summary row into a 260-pixel bounded `Instructions` card containing the exact durable result text; the existing trajectory `Inspect` handoff remains available below the card.
The row derives every visible value from a paired call/result slice in the current runtime window. It reads the skill name from the recorded `name` argument and the instructions from durable result content, and never joins the current skill catalog for descriptions or provider metadata. If pagination leaves the call outside the window, the result has no tool identity and remains on the generic fallback rather than extending the history wire contract. The existing ACP `skill-load` recording is seeded through the real Web persistence and composition path for a keyless interaction and accessibility snapshot.
## Alternatives considered
- Keep the generic tool row and add only a `skill` color selector in `ui-conversation`. This leaves the redundant input envelope and generic expanded body in place, and makes the conversation package own a domain-specific visual rule.
- Add a new `skill` value to the host tool render-intent union. The keyed client slot already identifies this tool when its call is in the runtime window, so a new cross-boundary presentation value adds protocol and snapshot surface without enabling another consumer.
- Export the conversation package's private `ToolRow` component for reuse. Client packages intentionally expose contracts rather than cross-package components; exporting it would couple independent feature packages to conversation implementation details.
## Consequences
`ui-skill` now depends on the public conversation toolview contract, locale and primitive packages, and React in addition to its reference-source dependencies. It owns a small copy of the disclosure-row chrome, so future global interaction changes must update this registrant alongside the Bash sample and conversation rows.
Cold replay stays deterministic when the installed skill catalog changes, and the transcript remains compact until instructions are explicitly expanded. A result-only history page intentionally uses the generic fallback; keeping this edge case generic preserves the existing history protocol and confines the feature to client presentation. The dedicated card intentionally shows the tool's complete framed output rather than extracting only `<skill_instructions>`, preserving exactly what reached the model and avoiding a second parser for the skill result format.

# Agent Note: Web skill 工具行
Status: implemented
[English](2026-08-06-web-skill-tool-row.md) | 中文
## 问题
Web transcript文本记录通过通用后备行渲染 `skill` 调用,使已加载的指令集看起来像一次未知工具调用,尽管 Skill技能已是产品中的一等概念。通用行还会在结果旁暴露 JSON 参数的外层结构,围绕用户真正需要的唯一标识增加了噪声:已加载的 skill 名称。
## 决策
`ui-skill` 在现有的 `conversation.chat.toolview` 键控 slot 下注册 key 为 `skill` 的组件。该组件基于公开的 `ToolRowProps` 契约自行实现行 chrome沿用 Bash 示例的独立注册方姿态,而不导入 conversation 私有组件。
收起的行使用 14 像素的文档与闪光组合图标,并沿用 Bash 行的中性色层级:图标采用三级色,`Skill` 标题采用二级色,分隔符采用 caption 色skill 名称采用三级色。运行、失败和中断调用分别沿用 transcript 的扫光、错误状态点加首行摘要,以及警告状态点语义。已结算调用可以通过整个摘要行展开一个高度上限为 260 像素的 `Instructions` 卡片,其中原样呈现持久化结果文本;用于跳转至 trajectory 的现有 `Inspect` 入口仍保留在卡片下方。
该行的所有可见值均派生自当前 runtime 窗口中已配对的调用结果片段。skill 名称来自已记录的 `name` 参数,指令来自持久化的结果内容;该行绝不关联当前 skill 目录来读取描述或提供方元数据。如果分页将调用留在窗口外,结果便没有工具身份,并继续使用通用后备路径,而不是扩展 history 协议契约。现有的 ACPAgent Client Protocol`skill-load` 记录经由真实的 Web 持久化与组合路径写入,用于无需密钥的交互和无障碍快照。
## 考虑过的替代方案
- 保留通用工具行,只添加一个 `skill` 颜色选择器,并将其放在 `ui-conversation` 中。该方案仍会保留多余的输入外层结构和通用展开体,也会让 conversation 包拥有特定领域的视觉规则。
- 在宿主工具渲染意图联合类型中添加新的 `skill` 值。键控客户端 slot 在调用位于 runtime 窗口内时已经能够识别该工具,因此新的跨边界呈现值只会增加协议和快照表层,却不会支持其他消费方。
- 导出 conversation 包的私有 `ToolRow` 组件供复用。客户端包刻意对外暴露契约而非跨包组件;导出该组件会使独立功能包耦合到 conversation 的实现细节。
## 后果
除了引用 source 的依赖外,`ui-skill` 现在还依赖公开的 conversation toolview 契约、locale 包、原语包和 React。它自行保留了一小份折叠展开行 chrome因此未来的全局交互变更必须与 Bash 示例和 conversation 行同步更新这个注册方。
即使已安装的 skill 目录发生变化冷回放仍保持确定性在用户显式展开指令前transcript 保持紧凑。仅含结果的 history 页有意使用通用后备路径;让这个边缘情况保持通用呈现,可以保留现有 history 协议,并将该功能限定在客户端呈现层。专用卡片有意显示工具完整封装的输出,而不是只提取 `<skill_instructions>`,从而原样保留模型实际收到的内容,也避免为 skill 结果格式再引入一个解析器。

# Agent Note: The documentation site carries its own images
Status: implemented
English | [中文](2026-08-06-doc-site-carries-its-images.zh.md)
## Problem
`scripts/project-doc-site.ts` rewrote every repository-relative target that the publication manifest does not publish into a GitHub URL, and for an image that meant `https://raw.githubusercontent.com/<owner>/<repo>/<ref>/<path>`. Nothing in the site build copies files: `srcDir` is the disposable `.generated` tree, VitePress sets no `publicDir` (its default, `<srcDir>/public`, is inside the tree the projector deletes on every run), and only Markdown is written there.
That works only for a public repository. This one is private, and `raw.githubusercontent.com` answers 404 to an unauthenticated request — a browser session on github.com does not authenticate it either, since GitHub's own UI serves private blobs through separately signed URLs. Every image on the site was therefore broken for every reader, and no gate said so: `verify-md-links` and the projector check that the target file *exists in the repository*, which is a different question from whether a site reader can fetch it.
## Decision
`rewriteMarkdown` takes an optional `placeImage(absPath): string`. When a page references an image the manifest does not publish as a page, the projector copies that file into the generated tree beside the page and rewrites the reference to `./<basename>`; Vite then bundles it like any other site asset. Nothing about repository visibility can reach the published page.
The copy lands beside the page rather than in a shared asset directory. Each locale's route tree gets its own copy, so one relative URL is correct from both `guide/` and `en/guide/` without computing per-locale prefixes, and a page's assets are removed with the page when the manifest drops it. One map claims every projected path — pages and images alike — so a second source for one path throws, in the same spirit as the existing duplicate-route check, rather than letting whichever wrote last win.
Only a regular file whose real path stays inside the repository is copied; anything else fails the projection naming the page and the target. Link rewriting needs to know a target *exists*, but publication copies its bytes onto the site, so a reference escaping the repository — through `../..` or a symlink out of the tree — would put a build-machine file on a published page. The reference's `?query` or `#fragment` rides along to the placed URL exactly as the GitHub branch has always carried it, and the file name is percent-encoded because the destination is a Markdown inline target.
`docsSourceFiles()` reports the placed images alongside the Markdown, so the dev server's watcher re-projects when a screenshot is replaced instead of serving the previous copy until something touches the page.
`placeImage` is optional because `rewriteMarkdown` is also called directly by its spec, where no generated tree exists. Without it the old GitHub-raw behavior stands, which keeps that seam honest: the fallback is still the correct answer for a consumer that only rewrites text.
Canonical Markdown keeps writing ordinary repository-relative image paths, so the same file renders on GitHub and on the site. No document carries a site-absolute URL to satisfy VitePress.
## Alternatives considered
**Set `publicDir` outside `.generated` and reference site-absolute URLs.** Fewer moving parts in the projector, but every image reference would then be broken when the same Markdown is read in the repository, and canonical docs are read both ways.
**Host images on the assets branch, as demo GIFs already are.** That branch exists to keep large binaries out of the main history, and its raw URLs have exactly the same visibility problem. It remains the right home for recordings; it does not solve this.
**Wait for the repository to become public.** It would fix the symptom without making the site self-contained, and the site would silently depend on GitHub's availability and rate limits for every image.
## Consequences
Images in published documentation now work regardless of who is reading or whether the repository is public, and the site build has no runtime dependency on GitHub for them. The generated tree grows by one copy of each referenced image per locale — the four screenshots in the model-provider guide add roughly 270 KB per locale.
Images referenced from *unpublished* documents are untouched: they still resolve to GitHub raw, and still fail for a private repository. Nothing consumes them today, and a document that is not on the site has no site build to carry its assets.
## Testing
`scripts/project-doc-site.spec.ts` covers the placer receiving the resolved absolute path and the returned URL landing in the Markdown, a placed reference keeping its fragment, a published page link still resolving to its route when a placer is present, and the unchanged GitHub-raw fallback when no placer is supplied. `publishableImage` is covered directly: a regular file inside the repository resolves, while a symlink whose target escapes it, a path outside it, and a directory are all refused. `pnpm docs:check` builds the site with the model-provider guide's screenshots and fails on a missing source; the copied files and their `./<basename>` references were verified in `website/.generated` and in a running `docs:dev` (`naturalWidth > 0` in both locales).

# Agent Note: 文档站点自带图片
Status: implemented
[English](2026-08-06-doc-site-carries-its-images.md) | 中文
## Problem
`scripts/project-doc-site.ts` 会把发布清单未收录的仓库相对目标一律改写成 GitHub 地址,对图片而言就是 `https://raw.githubusercontent.com/<owner>/<repo>/<ref>/<path>`。站点构建不拷贝任何文件:`srcDir` 是用完即弃的 `.generated`VitePress 没有设置 `publicDir`(其默认值 `<srcDir>/public` 恰好位于投影每次运行时删除的那棵树里),而写进去的只有 Markdown。
这只对公开仓库成立。本仓库是私有的,而 `raw.githubusercontent.com` 对未认证请求一律回 404——github.com 上的登录会话也不能认证它,因为 GitHub 自家界面是用另一套单独签名的地址提供私有 blob 的。于是站点上的每一张图片对每一位读者都是坏的,却没有任何门禁能说出来:`verify-md-links` 与投影校验的是目标文件**在仓库里是否存在**,那与站点读者能否取到它是两个问题。
## Decision
`rewriteMarkdown` 新增可选的 `placeImage(absPath): string`。当页面引用了一张清单未作为页面发布的图片时,投影把该文件复制进生成树中该页面的旁边,并把引用改写为 `./<basename>`;随后 Vite 会像处理其他站点资源一样打包它。仓库可见性再也影响不到已发布页面。
副本落在页面旁边,而不是某个共享资源目录。每个 locale 的路由树各持一份副本,因此同一个相对 URL 在 `guide/``en/guide/` 下都正确,无需按 locale 计算前缀;清单撤下某页时,它的资源也随之消失。一张表登记所有被投影的路径——页面与图片一视同仁——同一路径出现第二个来源就抛错,与既有的重复路由检查同一个立场,而不是让最后写入的那个静默胜出。
只有真实路径位于仓库内的普通文件才会被拷贝,其余一律让投影失败并点名页面与目标。链接改写只需要知道目标**存在**,但发布是把它的字节拷上站点,因此一个逃出仓库的引用——经由 `../..` 或指向树外的符号链接——会把构建机上的文件放到已发布页面上。引用自带的 `?query``#fragment` 会随安置后的 URL 一同保留,与 GitHub 分支一贯的做法一致;文件名做百分号编码,因为目标位于 Markdown 内联目标的位置。
`docsSourceFiles()` 会连同被安置的图片一起上报,于是替换截图时开发服务器的 watcher 会重新投影,而不是一直服务旧副本直到有人碰一下页面。
`placeImage` 之所以可选,是因为 `rewriteMarkdown` 也被它自己的 spec 直接调用,而那里并不存在生成树。不传它时保持原有的 GitHub raw 行为,这也让该接缝保持诚实:对只改写文本的消费方而言,这个回退仍是正确答案。
正本 Markdown 照旧写普通的仓库相对图片路径,因此同一份文件在 GitHub 上和站点上都能正常显示。没有任何文档为了迁就 VitePress 而写站内绝对 URL。
## Alternatives considered
**把 `publicDir` 设到 `.generated` 之外,并使用站内绝对 URL。** 投影这边的活动部件更少,但同一份 Markdown 在仓库中阅读时,每一处图片引用都会是坏的,而正本文档是两种方式都要读的。
**把图片放到 assets 分支,就像演示 GIF 那样。** 那个分支的存在是为了让大体积二进制不进主线历史,而它的 raw 地址有着完全相同的可见性问题。它仍然是录屏的正确归宿;但它解决不了这件事。
**等仓库转为公开。** 那只是消除症状,不会让站点自给自足,而且每一张图片都会让站点隐式依赖 GitHub 的可用性与限流。
## Consequences
已发布文档中的图片,现在无论谁在阅读、无论仓库是否公开都能显示,站点构建也不再为图片依赖 GitHub 的运行时可达性。生成树会为每个 locale 各增加一份被引用图片的副本——配置模型指南里的四张截图,每个 locale 约 270 KB。
**未发布**文档引用的图片不受影响:它们仍解析到 GitHub raw对私有仓库仍然失败。今天没有任何消费方用到它们而不在站点上的文档也没有站点构建可以承载其资源。
## Testing
`scripts/project-doc-site.spec.ts` 覆盖placer 收到解析后的绝对路径且其返回的 URL 落进 Markdown、被安置的引用保留其 fragment、存在 placer 时已发布页面的链接仍解析到自己的路由、以及不传 placer 时不变的 GitHub raw 回退。`publishableImage` 另有直接覆盖:仓库内的普通文件被接受,而目标逃出仓库的符号链接、仓库外的路径与目录一律拒绝。`pnpm docs:check` 会带着配置模型指南的截图构建站点,并在来源缺失时失败;被拷贝的文件及其 `./<basename>` 引用已在 `website/.generated` 与运行中的 `docs:dev` 里核实(两个 locale 均 `naturalWidth > 0`)。

# Agent Note: Buffer-free feedback telemetry
Status: implemented
English | [中文](2026-08-06-buffer-free-feedback-telemetry.zh.md)
## Problem
Feedback-only telemetry must upload the session-log prefix only after recorded feedback. Retaining a deep-copied, redacted record for every projected event until that trigger duplicates the canonical session log and grows without a bound for a long-lived session that never records feedback.
## Decision
The telemetry coordinator provides `live` and `on-demand` capture. On-demand capture registers no session, flush, or operational-event listeners and retains no projected records. `captureSession(session, throughSeq?)` reads the canonical session log after the handoff cursor through an optional inclusive sequence boundary, applies the fixed projection, deep-copies each accepted event, runs the current `telemetry/record` waterfall, and hands the result to the backend.
`FEEDBACK_ONLY` invokes that method with the `feedback/record` event's sequence. The append is already committed when `session/event` listeners run, so the replay contains the feedback event and cannot include a later suffix. The existing handoff cursor distinguishes later replays without another pending-record index.
Because on-demand capture reads only the canonical log, it emits no `agent-error` or `shutdown` operational records. Redaction is evaluated at feedback time rather than append time. The [feedback mode decision](../feature/2026-08-05-feedback-gated-session-telemetry.md) owns the public sharing behavior; this note owns its buffer-free realization.
## Alternatives considered
**Retain capture-time redacted records.** This preserves the exact redaction policy and operational records observed when each event occurs, but duplicates the unbounded session prefix. The mode promises feedback-triggered session-log upload, not capture-time policy snapshots or pre-feedback operational telemetry.
**Retain session event references or sequence numbers.** Rejected because the canonical log already supplies both order and identity. A second index saves payload copies but adds lifecycle state without enabling any required behavior.
**Write a durable pre-feedback spool.** Deferred until a deployment requires crash recovery before feedback. It adds storage, cleanup, and confidentiality policy to a mode whose intended behavior is to upload nothing when the process exits before feedback.
## Consequences
A no-feedback session consumes no telemetry-owned memory proportional to its event count; the canonical session log remains the only pre-feedback copy. Feedback handling performs projection, cloning, and redaction synchronously before the backend's non-blocking enqueue, so its cost scales with the unreleased prefix. A redaction-policy change before feedback affects that replay, and a crash before feedback uploads nothing. Later feedback processes only events beyond the handoff cursor.

# Agent Note: 无缓冲反馈遥测
Status: implemented
[English](2026-08-06-buffer-free-feedback-telemetry.md) | 中文
## 问题
仅反馈遥测必须只在记录反馈后上传会话日志前缀。若在触发前为每个已投影事件保留一份已深拷贝、已脱敏的记录,就会复制权威会话日志;对于长期运行但从不记录反馈的会话,这份副本会无限增长。
## 决策
遥测协调器提供 `live``on-demand` 捕获。按需捕获不注册会话、flush 或运维事件监听器,也不保留投影记录。`captureSession(session, throughSeq?)` 从 handoff 游标之后读取权威会话日志,直至可选的序列号边界(含边界),应用固定投影、深拷贝每个已接受事件、运行当前的 `telemetry/record` waterfall瀑布式事件并将结果交给后端。
`FEEDBACK_ONLY``feedback/record` 事件的序列号调用该方法。`session/event` 监听器运行时,追加已经提交,因此回放包含该反馈事件,且无法包含后续后缀。现有 handoff 游标可区分后续回放,无需另一个待处理记录索引。
按需捕获只读取权威日志,因此不会发出 `agent-error``shutdown` 运维记录。脱敏在反馈时而非追加时求值。[反馈模式决策](../feature/2026-08-05-feedback-gated-session-telemetry.md)规定公开的共享行为;本记录规定其无缓冲实现。
## 考虑过的替代方案
**保留捕获时的已脱敏记录。** 该方案会保留每个事件发生时观察到的确切脱敏策略与运维记录,但也会复制无上限的会话前缀。该模式承诺在反馈触发后上传会话日志,而非保留捕获时策略快照或反馈前运维遥测。
**保留会话事件引用或序列号。** 已否决,因为权威日志已同时提供顺序与身份。第二个索引可以省去载荷副本,但会增加生命周期状态,且无法实现任何必需行为。
**写入持久化的反馈前 spool。** 推迟到有部署要求反馈前的崩溃恢复时再实现。该方案会为一个预期在进程于反馈前退出时不上传任何内容的模式增加存储、清理与保密策略。
## 后果
没有反馈的会话不会消耗随事件数量增长的遥测自有内存;权威会话日志仍是反馈前的唯一副本。反馈处理会在后端非阻塞入队前同步执行投影、深拷贝与脱敏,因此其开销随未释放前缀增长。反馈前的脱敏策略变更会影响该次回放,而反馈前发生崩溃时什么都不上传。后续反馈只处理 handoff 游标之后的事件。

# Agent Note: User and steering bubbles drop the branch action
Status: implemented
English | [中文](2026-08-06-user-bubbles-drop-the-branch-action.zh.md)
## Problem
Every user and consumed-steering bubble rendered the branch control under the completed-turn-tail gate of the [completed-turn-tail decision](../bug-fix/2026-08-02-message-fork-actions-require-completed-turn-tail.md). On those bubbles the gate is effectively permanent: a turn-opening user message is followed by its own turn's nodes, and a consumed steering message is mid-turn by construction, so the control could enable only when the turn ended with no node after the message at all — a cancel before the first model event. Readers therefore saw a control that never enables, with a tooltip promising a state the button cannot reach. The affordance also misled when read at all: a fork at a message seq cuts at the containing `turn/end`, so "branch at my message" includes the answer below it — the opposite of the branch-to-re-ask reading a control on one's own bubble suggests.
## Decision
User and steering bubbles render no branch action. `MessageItem` loses its fork props, `PendingSteeringBubble` loses its `showBranch` special case, and `messageBranchSeqs` narrows to `assistantBranchSeqs`: only a completed turn's transcript tail that is the turn's own content-text assistant may fork. The branch affordance lives solely under the settled answer.
A turn containing a steer keeps its fork point unchanged: fork is a log-prefix cut at `turn/end`, and the steer is model-visible history the child must inherit, so the settled answer of a steered turn forks like any other. The assistant-side gate and its visible-but-unavailable presentation are also unchanged — under an answer, unavailable is a transient, reachable state (a trailing tool or error row currently owns the tail), which is exactly what the tooltip is for.
## Alternatives considered
**Hide the control on message bubbles only while ineligible.** Rejected: it preserves the near-unreachable enabled case at the cost of an icon that appears on one's own bubble only when a turn died before producing anything, an inconsistency not worth the case it serves.
**Keep the visible-but-unavailable control (status quo).** Rejected: the [completed-turn-tail decision](../bug-fix/2026-08-02-message-fork-actions-require-completed-turn-tail.md) chose visibility so the tooltip could explain a boundary the reader can reach; on user and steering bubbles the boundary is unreachable in practice, so the explanation props up a control that should not exist there.
**Branch-before-the-message semantics on user bubbles.** Out of scope: re-asking from one's own prompt needs a cut before the message plus composer prefill, a different Host operation. Removing the current control keeps that seat free for such a feature instead of squatting on it with opposite semantics.
## Consequences
The only fork handles are the enabled branch controls under settled answers. A turn cancelled before any node followed its message loses its only handle and has no fork point, matching turns whose tail is a content-free interrupted node. Web aria goldens across `apps/web` drop the user-bubble disabled-branch row and its hidden explanation text. Package tests pin that user and steering bubbles render no branch control and that a steering-tail turn leaves the narration's control unavailable.

# Agent Noteuser 与 steering 气泡移除分支操作
Status: implemented
[English](2026-08-06-user-bubbles-drop-the-branch-action.md) | 中文
## 问题
每个 user 气泡和已消费的 steering中途引导气泡都渲染分支控件受[已完成轮次尾部决策](../bug-fix/2026-08-02-message-fork-actions-require-completed-turn-tail.md)的门禁约束。在这些气泡上,该门禁实际上是永久性的:开轮的 user 消息后面必然跟着本轮自己的节点,已消费的 steering 消息按构造就处在轮次中间因此只有当轮次结束时该消息之后一个节点都没有——即在第一个模型事件之前就取消——控件才可能启用。读者因此看到一个永远不会启用的控件tooltip 许诺的是这个按钮到达不了的状态。这个操作入口本身也有误导:在消息 seq 处 fork 会切在所在轮次的 `turn/end`"在我的消息处分支"实际会把下方的回答一并带走,与在自己气泡上看到分支时"分叉重问"的直觉预期恰好相反。
## 决策
user 与 steering 气泡不再渲染分支操作。`MessageItem` 移除其 fork props`PendingSteeringBubble` 移除其 `showBranch` 特例,`messageBranchSeqs` 收窄为 `assistantBranchSeqs`:只有已完成轮次的 transcript 尾部、且该尾部是本轮自己的带 text 内容 assistant 节点才可 fork。分支入口只存在于已定稿的回答之下。
含有 steer 的轮次的 fork 点保持不变fork 是切在 `turn/end` 上的日志前缀steer 是子会话必须继承的模型可见历史,因此被引导过的轮次的已定稿回答与其他轮次一样可以 fork。assistant 侧的门禁及其可见但不可用的呈现也保持不变——在回答之下,不可用是一个短暂且可到达的状态(当前尾部被后续工具行或错误行占据),这正是 tooltip 的用武之地。
## 考虑过的替代方案
**仅在不可用时隐藏消息气泡上的控件。** 否决:它保住了那个几乎不可达的启用场景,代价是图标只在轮次尚未产出任何东西就中止时才出现在自己的气泡上,这种不一致不值得为它服务的场景付出。
**保留可见但不可用的控件(现状)。** 否决:[已完成轮次尾部决策](../bug-fix/2026-08-02-message-fork-actions-require-completed-turn-tail.md)选择可见,是为了让 tooltip 解释一个读者可以到达的边界;在 user 与 steering 气泡上这个边界实际不可达,解释文本是在为一个不该存在于此的控件打补丁。
**在 user 气泡上采用切在消息之前的分支语义。** 不在本次范围内:从自己的提示词重问需要切在消息之前并预填输入框,是另一个 Host 操作。移除当前控件恰好为这样的功能留出位置,而不是让语义相反的控件占着它。
## 后果
唯一的 fork 入口是已定稿回答下方启用的分支控件。在任何节点跟上其消息之前就被取消的轮次失去了它唯一的入口,从此没有 fork 点,与尾部是无内容 interrupted 节点的轮次一致。`apps/web` 的 aria golden 全部移除 user 气泡的禁用分支行及其隐藏说明文本。包测试钉住user 与 steering 气泡不渲染分支控件steering 作为尾部的轮次让叙述节点的控件保持不可用。

A separate interaction contract over the same fixture pins heterogeneous-row order, independent adjacent tool disclosure, exact user-message clipboard content, a turn-bounded message fork, source/child isolation, and a real follow-up turn in the child; wheel input only navigates to semantic targets and carries no geometry expectation.

- An image is the exception: its file is copied into the generated tree and referenced from there, so the site serves it regardless of repository visibility. It must be a regular file inside the repository.
- External URLs, site-absolute URLs, email links, and fragment-only links remain unchanged.
- A missing repository-relative target fails projection instead of silently producing a broken link.
