From d60dea9f55b7cc383b0bd4347788a25c1f01625e Mon Sep 17 00:00:00 2001 From: Tianyi Cui <53024+tianyicui@users.noreply.github.com> Date: Sun, 26 Jul 2026 02:43:34 +0800 Subject: [PATCH 01/64] feat(tools): run_code description param + native-parity dispatch logging + web code-mode seam MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit run_code gains a required bash-style description parameter: presentCall titles the card with it and moves the program to rawInput, so every surface gets a readable label. tool/code-dispatch now logs each sub-call's complete content/isError (the tool/result vocabulary), replacing the bounded resultSummary and deleting the summarize/cwd machinery — a UI renders sub-calls through the identical path as native results. The dsh config tree mounts the worker code runtime and reads DSH_TOOLS_MODE (temporary seam until per-session mode selection lands). Session format stays v0 (pre-release churn). Code-mode ACP/TUI fixtures re-recorded; TUI presenter pin refreshed; catalogs regenerated. Keyless web smoke pins the code-mode wire contract (tools=[run_code] + SDK prompt section). --- ...0-canonical-tool-output-contract.i18n.yaml | 4 +- ...26-07-20-canonical-tool-output-contract.md | 2 +- ...07-20-canonical-tool-output-contract.zh.md | 2 +- ...de-mode-result-card-completeness.i18n.yaml | 4 +- ...7-20-code-mode-result-card-completeness.md | 2 +- ...0-code-mode-result-card-completeness.zh.md | 2 +- .../feature/2026-06-15-code-mode.i18n.yaml | 4 +- .../feature/2026-06-15-code-mode.md | 4 +- .../feature/2026-06-15-code-mode.zh.md | 4 +- ...-20-code-mode-typed-tool-returns.i18n.yaml | 4 +- ...2026-07-20-code-mode-typed-tool-returns.md | 2 +- ...6-07-20-code-mode-typed-tool-returns.zh.md | 2 +- .../2026-07-26-code-dispatch-ui-foundation.md | 31 + apps/cli/cordis.yml | 12 + apps/cli/package.json | 1 + apps/web/tests/smoke-real.e2e.ts | 77 ++ docs/core-data-structures/tools.i18n.yaml | 4 +- docs/core-data-structures/tools.md | 2 +- docs/core-data-structures/tools.zh.md | 2 +- docs/persistence-catalog.md | 15 +- docs/tool-catalog.md | 7 +- .../snapshots/code-mode-turn/session.jsonl | 974 ++++++------------ .../code-mode-turn/system-prompt.expected.md | 2 +- .../code-mode-turn/tool-schemas.expected.json | 7 +- .../code-mode-workspace-context/session.jsonl | 430 ++++---- .../stdout.expected.jsonl | 2 +- .../system-prompt.expected.md | 2 +- .../tool-schemas.expected.json | 7 +- .../headless-agent/tests/code-mode.e2e.ts | 2 +- .../tests/snapshots/code-mode/session.jsonl | 669 ++++++++---- .../snapshots/code-mode/terminal.expected.txt | 115 ++- packages/core/tools/README.md | 4 +- packages/core/tools/src/code-mode.ts | 61 +- packages/core/tools/tests/code-mode.spec.ts | 99 +- .../plan/plan-mode/tests/plan-mode.spec.ts | 2 +- .../spill-policy/tests/spill-policy.spec.ts | 1 + .../tests/structured.spec.ts | 6 +- .../snapshots/code-mode-pending.expected.txt | 29 +- packages/ui/tui/tests/tui.snapshot.ts | 1 + pnpm-lock.yaml | 3 + 40 files changed, 1312 insertions(+), 1291 deletions(-) create mode 100644 .agents/notes/implemented/feature/2026-07-26-code-dispatch-ui-foundation.md diff --git a/.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.i18n.yaml b/.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.i18n.yaml index d28fb0da87..14a271f3c7 100644 --- a/.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.i18n.yaml +++ b/.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

The outer `run_code` call alone produces one card and may spill its final post-policy presentation; `run_code` intentionally declares neither a result presenter nor presentation metadata, so UI adapters complete the card through their generic raw-content fallback using durable `tool/result.content`. diff --git a/.agents/notes/implemented/feature/2026-07-20-code-mode-typed-tool-returns.zh.md b/.agents/notes/implemented/feature/2026-07-20-code-mode-typed-tool-returns.zh.md index 70fd9ee728..fea1be3e23 100644 --- a/.agents/notes/implemented/feature/2026-07-20-code-mode-typed-tool-returns.zh.md +++ b/.agents/notes/implemented/feature/2026-07-20-code-mode-typed-tool-returns.zh.md @@ -73,7 +73,7 @@ Code Mode 通过运行时请求中的 `{ name: "ToolCallError", memberNameProper ### 持久化、元数据与输出落盘 -嵌套分发会为诊断保留既有的有界 `tool/code-dispatch.resultSummary`，但不会持久化规范值。`tool/result` 继续只持久化渲染后的内容、错误和可选元数据。这并非会话格式变更，因此 `SESSION_FORMAT_VERSION` 保持不变，回放也无法重建程序的中间值。 +嵌套分发在 `tool/code-dispatch` 上记录子调用完整渲染后的 `content`/`isError`，但不会持久化规范值。`tool/result` 继续只持久化渲染后的内容、错误和可选元数据。`SESSION_FORMAT_VERSION` 保持不变（预发布阶段的形状变动不递增版本号），回放也无法重建程序的规范中间值。 不透明的 `exec.parent` token 用于标识嵌套调用。由于这些调用没有直接对应的结果卡片，而且其规范值永远不会进入上下文，展示元数据以及通用或工具自有的输出落盘投影都会跳过它们。只有外层 `run_code` 调用会生成一张卡片，并且可能将 post-policy 处理后的最终展示写入落盘文件；`run_code` 有意既不声明结果展示器，也不声明展示元数据，因此 UI 适配器会通过通用的原始内容回退机制，使用持久化的 `tool/result.content` 补全该卡片。 diff --git a/.agents/notes/implemented/feature/2026-07-26-code-dispatch-ui-foundation.md b/.agents/notes/implemented/feature/2026-07-26-code-dispatch-ui-foundation.md new file mode 100644 index 0000000000..a1629c7730 --- /dev/null +++ b/.agents/notes/implemented/feature/2026-07-26-code-dispatch-ui-foundation.md @@ -0,0 +1,31 @@ +# Agent Note: Code Mode UI foundation — run_code description and native-parity dispatch logging + +Status: implemented + +English | [中文](2026-07-26-code-dispatch-ui-foundation.zh.md) + +> Scope: the host-side contract changes that let a UI render a Code Mode turn with the same fidelity as native tool calls — the first PR of the Code Mode web-UI stack. The [Code Mode foundation](2026-06-15-code-mode.md) owns the transport design; this note owns the model-visible `description` parameter, the full-content `tool/code-dispatch` payload, and the temporary `DSH_TOOLS_MODE` enablement seam for the `dsh` config tree. + +## Problem + +A `run_code` turn was opaque in every product surface. The call card's title was the raw program text — unreadable at row width, and unlike `bash` (whose required `description` labels the card while the command rides the expanded input) there was no model-authored label at all. The `tool/code-dispatch` event carried only a 200-char, cwd-normalized `resultSummary` of each sub-call, so no UI could ever show what a sub-call actually returned: the planned web conversation view renders sub-calls through the exact components that render native `tool/result` cards, and a bounded summary cannot feed a native-parity card. And the `dsh web` composition had no way to enable Code Mode at all — the `tools` row pinned the schema default and the runtime was absent from the tree. + +## Decision + +Three changes, one per obstacle: + +1. **`run_code` gains a required `description` parameter** (bash's exact contract: active voice, 5-10 words, shown in the UI; whitespace-only rejected at execute). `presentCall` now titles the card with the description and moves the program to `rawInput`. The prompt-side cost is a few tokens per call; the return is that every surface — TUI card, ACP title, web row — gets a human-readable label without parsing TypeScript. +2. **`tool/code-dispatch` logs the sub-call's complete model-facing outcome** — `content: ContentBlock[]` + `isError`, the `tool/result` vocabulary — replacing `resultSummary` and deleting the summarize/cwd-normalization machinery outright. A UI renders a sub-call through the identical code path as a native result, including error text and non-text blocks. The event stays log-only (`deriveMessages()` ignores it): nothing about model context changes. +3. **`DSH_TOOLS_MODE` env var on the `dsh` config tree** (`native`|`code`|`both`; unset keeps the schema default): the `tools` row reads it via `!!js`, and the worker code runtime is mounted unconditionally (Loader metadata is static, so no conditional row exists; a native boot only registers the service — workers spawn per run). This is an explicitly temporary seam: per-session tool-mode selection owned by the web UI is the design goal, and the env var dies when that lands. + +## Alternatives considered + +**Keep a bounded summary (raised cap, or a cap + `truncated` flag).** Rejected: the stack's settled requirement is that sub-call rows and details render *identically* to native calls; any cap forces a second, degraded render path plus truncation UI. The cost accepted instead: a program that reads a large file logs the rendered content verbatim on the dispatch event — uncapped, outside spill policy, growing the session log by the same bytes. Spill integration for the logged copy is deferred to a later PR of this stack (the projection exists; wiring it into the bridge is mechanical once the event shape settles with the start/end pair). + +**A `--tools-mode` CLI flag or profile key.** Deferred, not rejected: the flag grammar suggests permanence, and the profile json is user config — both would harden a seam the per-session design intends to remove. An env var reads as the workaround it is. + +**Log the canonical `value` instead of rendered `content`.** Rejected: `tool/result` persists content, not values (the [canonical output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)), and native parity means matching that exactly; values remain execution-local everywhere. + +## Consequences + +Session format keeps `SESSION_FORMAT_VERSION` 0 (pre-release churn does not bump; old logs with `resultSummary` simply carry an extra unread field and lack `content` — v0 makes no compatibility promise). Existing code-mode snapshot fixtures were re-recorded. Model-visible surface grew: the `run_code` schema (one required parameter) and every code-mode system prompt/tool-schema snapshot changed. The web UI stack (subsequent PRs) builds directly on the new event payload; live per-sub-call running state needs a dispatch start/end pair that will reshape this event again. diff --git a/apps/cli/cordis.yml b/apps/cli/cordis.yml index b89df77c46..bd0c45f9f8 100644 --- a/apps/cli/cordis.yml +++ b/apps/cli/cordis.yml @@ -44,6 +44,18 @@ - id: tools name: '@deepseek-ai/dsh-tools' + config: + # TEMPORARY workaround: DSH_TOOLS_MODE (native|code|both) opts a whole dsh + # process into Code Mode while per-session tool-mode selection is being + # designed; unset keeps the schema default (native).

Presenters depend only on their Under `code` or `both`, the registry exposes the reserved `run_code` transport and a deterministic TypeScript SDK for the current scope; only the program's outer logs and return value re-enter model context. The SDK declares exact `ToolArgsMap` and `ToolOutputMap` entries for every visible tool, and each binding resolves to the tool's canonical JSON value. Each lossless-JSON binding call re-enters the complete tool pipeline sequentially with logged correlation to the outer call. Denials and other failed results reject with the real program-visible `ToolCallError` carrying only `toolName` and `message`; Native content and internal error codes stay outside the Code contract. Ordinary side effects are not rolled back, and sub-call `additionalContexts` are deferred through the parent result to preserve call/result adjacency. Run settlement aborts and drains outstanding bindings; runtime failures surface as `CodeRunFailedError`. See the [Code Mode foundation](../../../.agents/notes/implemented/feature/2026-06-15-code-mode.md), [typed-return contract](../../../.agents/notes/implemented/feature/2026-07-20-code-mode-typed-tool-returns.md), and [code-runtime seam](../../code-runtime/README.md). Try `pnpm run demo:code-mode`. - **The SDK section** (`tools:sdk`, order 150): a lazy prompt section regenerating, at each assembly, `JsonValue`, exact `ToolArgsMap` / `ToolOutputMap`, `ToolName`, the `ToolCallError` declaration, and a mapped `tools` namespace for the calling scope's visible end capabilities (exotic names via quoted keys), plus fixed usage instructions. Deterministic — lexicographic tool order, byte-identical text for an unchanged tool set (prefix-cache-friendly). The codegen (`jsonSchemaToTs`, exported) handles every unified schema construct and degrades unsupported raw constructs to `unknown`, never throwing during prompt assembly. -- **The dispatch bridge** (`run_code`'s execute): every binding call is snapshotted as lossless JSON before dispatch (`undefined`, `BigInt`, cycles, sparse arrays, `-0`, and exotic objects reject that one call), serialized through a per-run queue (even `Promise.all` executes underlying calls one at a time in submission order), given the outer execution's opaque token as `parent`, and run through the complete pre-execute → guards → execute → post-execute → result pipeline. A success returns the final canonical value after policy; a failure reaches the worker as one message and becomes `ToolCallError(toolName, message)`. Each sub-call is logged as a `tool/code-dispatch` session event with deterministic id `:code:` and a bounded Native-content summary; `deriveMessages()` does not surface that event or persist the value. Token correlation lets commit-style observers defer an inner success until the final `run_code` result without exposing the live outer execution; ordinary tool side effects are not rolled back. Every sub-call `additionalContexts` entry is deferred through the outer `ToolRunContext` in dispatch order; the loop appends those contexts only after the parent `run_code` result, preserving adjacency and retaining each source/meta even when the program later fails. +- **The dispatch bridge** (`run_code`'s execute): every binding call is snapshotted as lossless JSON before dispatch (`undefined`, `BigInt`, cycles, sparse arrays, `-0`, and exotic objects reject that one call), serialized through a per-run queue (even `Promise.all` executes underlying calls one at a time in submission order), given the outer execution's opaque token as `parent`, and run through the complete pre-execute → guards → execute → post-execute → result pipeline.

A failed run throws `CodeRunFailedError` (`code: 'CODE_RUN_FAILED'`, message = the failure kind + captured logs), which the pipeline converts to a structured `isError` the model self-corrects from. - **Result boundary**: intermediate binding values cross the worker boundary whole and have no per-binding byte cap. `run_code` returns canonical `{ logs: string[], result?: JsonValue }`; strings render raw, every other present JSON root renders through a stack-safe pretty JSON traversal whose total indentation is capped at ten characters (deeper subtrees stay compact), `null` remains explicit, and absent `result` means the program returned `undefined`. The worker's configurable `maxOutputBytes` (default 64 MiB) applies only to the combined serialized outer log-array, completion-value, or failure-message payloads; fixed result-envelope syntax and presentation whitespace are outside that ledger.

Cancel uses a hang patch with a readyFile marker — the marker proves the stream is parked mid-turn before the Stop click, so mid-stream cancellation is deterministic by construction (turn/end 'aborted', composer re-enabled). AUTH pins the non-retryable path: turn/end 'error', zero llm/retry events, composer recovers; FIXME(web-error-surface) marks the found product gap (no error copy renders — the client consumes no agent/error frames and a pre-chunk failure freezes no partial). SERVER retry appends the fixture's own success after an injected throw and proves llm-retry end-to-end in the browser via the durable llm/retry record. - question-composer: the shipped ask_user_question takeover blocks the turn mid-step on the real userInteraction seam; the test answers through the composer (the one sanctioned model-content-reactive drive step: the turn cannot complete without it) and the tool result carries the answer. Adds the composer waiting-state aria golden. - steering: steers mid-turn while the composer blocks the step (the deterministic mid-turn window). The steer rides the real wire (session.prompt mode:'steer' POSTed from the page; the locked composer has no steering gesture yet — TODO(web-steer-composer)); downstream is all product: gateway -> Agent.steer -> step-boundary drain -> durable steering/message -> SSE -> badged interjection bubble.

The [toolview dissolution](../architecture/2026-07-23-toolview-dissolution.md) owns the slot model this rides on. + +## Problem + +With Code Mode enabled, the chat view showed one opaque `run_code` row: raw program text as the summary, sub-calls invisible everywhere.

Live mux frames and history replay build the identical index (`rebuildDerivedFromWindow` clears and re-derives; copy-on-write per-parent arrays keep snapshot references memo-stable). Sub-calls never join `nodes` — the surface flow remains exactly the model-visible turn structure. The event is narrowed structurally at the wire-consumer boundary (dsh-tools' host types cannot enter the client program — the host/client `Context` merges collide), the same posture as every cross-wire payload. +- **Render layer**: `ChatView`'s `CallRow` renders the parent, then — for parents present in the index — a `[data-subcalls]` nest of `SubCallRow`s, each dispatching through the SAME `'conversation.chat.toolview'` keyed hole with `entryKey = sub-tool name` and the same `GenericToolCard` fallback. Identity with native rows holds by construction: a keyed registration (e.g. the bash sample) takes over sub-rows exactly as it takes over top-level rows, with zero registration changes. Running parents (`runningCalls`) nest their so-far dispatches the same way, so sub-rows stream in live during the run (PR1 logs each dispatch as it completes). +- **`run_code` presentation**: a new `code` row variant (classifier `run_code → code`, `Code` title, `IconCodeOutline16`) summarizes with the model-authored `description` and expands to the program itself (monospace on the markdown code-block fill) rather than the args JSON envelope. +- **Details panel**: `materialFor` falls through nodes → runningCalls → the dispatch index, so a selected sub-callId resolves to full args and complete output through the identical rendering path as a native settled call. + +## Alternatives considered + +**Sub-calls flat in the surface flow (fold them into `nodes`).** Rejected: misrepresents the transcript — the model made one call; nesting under the parent preserves the code↔calls association and keeps the fold's model-visible-order invariant untouched. + +**Hidden until the parent row expands.** Rejected by product decision: the sub-calls ARE the story of a Code Mode turn; hiding them re-creates the opacity this feature removes. The parent's expand toggle reveals only the program. + +**A dedicated sub-call row component.** Rejected: the whole point is identity with native rows; a parallel component would drift. The nest wrapper (indent + left edge) is the only sub-call-specific chrome. + +## Consequences + +Custom toolview registrations apply to sub-calls for free — and deliberately: there is no per-registration opt-out short of the component reading its own context, which no current consumer needs. Selection highlighting reaches nested rows through the same `selectedCallId` channel (group membership tests both levels). Trajectory/waterfall still render `run_code` as a single row — their sub-call spans are deferred to the PR that adds dispatch timing (start/end events), without which a waterfall span would be a lie.

+[English](2026-07-26-code-mode-chat-subcall-rows.md) | 中文 + +> 范围：web chat 视图如何渲染一个 `run_code` 轮次，即 Code Mode UI 堆叠 PR（Pull Request）链的 client 侧一半，构建在[宿主侧基础](2026-07-26-code-dispatch-ui-foundation.md)之上（携带完整内容的 `tool/code-dispatch`、必填的 `description` 参数）。本篇所依托的 slot 模型归 [toolview 溶解](../architecture/2026-07-23-toolview-dissolution.md)所有。 + +## 问题 + +启用 Code Mode 后，chat 视图过去只显示一条不透明的 `run_code` 行：摘要就是原始程序文本，子调用则处处不可见。已敲定的产品要求恰恰相反：每个子调用都必须与原生工具调用渲染得*完全一致*——同样的行组件、同样的自定义注册、同样的 details 面板——同时 transcript（文本记录）仍须如实反映模型只发起了一次调用这一事实。 + +## 决策 + +**子调用是 surface 流之外单独索引的 `ToolResultNode`，经由与原生行相同的 keyed slot 渲染，以始终可见的方式嵌套在父行之下。** + +- **数据层**：`Session.applyEventSideEffects` 把窗口内的每条 `tool/code-dispatch` 折入 `ConversationSnapshot.codeDispatches: ReadonlyMap`，其中 `CodeSubCall` 本身就是 `ToolResultNode`（子调用 id 充当 `callId`，已记录的参数经 JSON 字符串化写入 `call.argsRaw`，完整记录的 `content`/`isError` 原样携带）。live mux 帧与历史回放构建出同一份索引（`rebuildDerivedFromWindow` 先清空再重新推导；按父级写时复制（copy-on-write）的数组保持快照引用 memo 稳定）。子调用永不进入 `nodes`——surface 流始终精确等于模型可见的轮次结构。该事件在协议（wire）消费方边界作结构性收窄（dsh-tools 的 host 类型进不了 client 程序——host/client 两侧的 `Context` 声明合并会冲突），姿态与所有跨协议载荷一致。 +- **渲染层**：`ChatView` 的 `CallRow` 先渲染父行，随后对索引中出现的父级渲染一组 `[data-subcalls]` 嵌套的 `SubCallRow`，每一行都经由同一个 `'conversation.chat.toolview'` keyed 孔位、以 `entryKey = sub-tool name` 分发，并共用同一个 `GenericToolCard` fallback。与原生行的同一性由构造保证：一个 keyed 注册（例如 bash 样例）接管子行与接管顶层行的方式完全相同，注册本身零改动。运行中的父调用（`runningCalls`）也以同样的方式嵌套目前已产生的分发，因此子行在运行期间实时流入（PR1 在每次分发完成时即记录该分发）。 +- **`run_code` 的呈现**：新增一种 `code` 行变体（分类器映射 `run_code → code`、标题 `Code`、图标 `IconCodeOutline16`）：摘要使用模型撰写的 `description`，展开后显示程序本身（在 markdown 代码块填充上以等宽字体呈现），而不是参数的 JSON 信封。 +- **details 面板**：`materialFor` 按 nodes → runningCalls → 分发索引的顺序逐级回落，因此被选中的子调用 callId 会经由与原生已完结调用完全相同的渲染路径，解析出完整参数与完整输出。 + +## 曾考虑的替代方案 + +**把子调用平铺进 surface 流（折入 `nodes`）。** 否决：这会歪曲 transcript——模型只发起了一次调用；嵌套在父行之下既保住代码↔调用的关联，也让 fold 的模型可见顺序不变式原封不动。 + +**隐藏子调用，展开父行后才显示。** 由产品决策否决：子调用正是一个 Code Mode 轮次的核心内容；把它们藏起来，等于重新制造出本功能所要消除的那种不透明。父行的展开开关只用于显示程序本身。 + +**专用的子调用行组件。** 否决：本功能的全部要义就在于与原生行保持同一性；一个平行组件必然漂移。嵌套包装层（缩进 + 左侧边线）是子调用唯一的专属 chrome。 + +## 后果 + +自定义 toolview 注册免费适用于子调用——而且是刻意为之：除了组件自行读取上下文之外，不存在按注册粒度的 opt-out 手段，而当前也没有任何消费方需要它。选中高亮经由同一条 `selectedCallId` 通道到达嵌套行（分组归属判断会同时检验两个层级）。trajectory/waterfall 仍把 `run_code` 渲染为单独一行——它们的子调用 span 推迟到增加分发计时（start/end 事件）的那个 PR；缺少计时，waterfall 上的 span 就是谎言。fixture（测试前置数据）的轮次 64（`?fixture`），加上 `code-mode-round` 浏览器 e2e（录制的真实 round、无密钥回放），共同锁定完整的产品表面；jsdom 套件则锁定 slot 分发、错误状态、details 解析与索引引用稳定性。

Asserts settled markdown, the aria golden, and inline world state (bash `tool/call`, completed `turn/end`, >10 chunk events). 2. **`seeded-history`** — a recorded session seeded cold; the sidebar lists it (group row → session row, collapsed by default), opening renders tool cards and text purely from the log through the implicit cold-resume attach inside `session.history` — zero model calls in replay, so no binding constraints; record mode drives the same turn live (real `read` tool against seeded workspace files) to produce the seed. +3. **`live-interactions`** — one tool-free recorded turn serves three replay-only scenarios through override sidecars whose CONTENT is authored in the spec and minted as a per-run file in a spec-owned temp dir (the derived success entry for the retry append is re-derived from the fixture via `deriveReplayScript`, never copied into a committed sidecar). Cancel: a `{ patches }` `hang` with a `readyFile` marker — the marker's existence proves the stream is parked mid-turn before the test clicks Stop, making mid-stream cancellation deterministic by construction (`turn/end` reason `aborted`, composer re-enabled). AUTH error: a pre-chunk `throw` outside llm-retry's retryable set (`turn/end` reason `error`, zero `llm/retry` events, composer recovers). SERVER retry: `throw` at call 0 + the fixture's own success appended at 1, proving llm-retry end-to-end in the browser via the durable `llm/retry` record (`request/header` logs only on change, so attempt count is invisible there). +4. **`question-composer`** — the shipped composition's resident `ask_user_question` takeover: a recorded turn blocks mid-step on the real userInteraction seam, the composer (`[data-question-key]`) renders in the browser, the test answers through it (the ONE sanctioned place a drive step reacts to model content: the turn cannot complete without the answer, in record and replay alike), and the tool result carries the chosen label. Golden: the composer's stable waiting state. +5. **`steering`** — mid-turn steer while the question composer blocks the step (the deterministic mid-turn window; no timing dependence). The composer locks while running, so the steer POSTs `session.prompt` `mode:'steer'` from the page over the same same-origin `/api` wire the client uses (`TODO(web-steer-composer)`: drive a composer gesture once one exists); everything downstream is product — gateway → `Agent.steer` → step-boundary drain → durable `steering/message` → SSE → badged interjection bubble. Record-mode fixture honesty: the recording is rejected unless the live model's final reply obeys an instruction only the steering message carries. ### CI stance @@ -77,13 +80,15 @@ Surveyed AI-chat/agent web UIs and mocking layers (LibreChat, vercel/ai-chatbot ## Testing -The lane itself: `pnpm run test:web` runs both scenarios keylessly alongside the existing smoke pair; `DSH_SNAPSHOT=record pnpm exec vitest run --config vitest.web.config.ts apps/web/tests/` re-records a scenario's fixture against the live model; `DSH_SNAPSHOT=refresh` rewrites both aria goldens keylessly. `paceMs` validation, pacing floor, abort-during-pace, and both `assertConsumed` failure shapes are pinned in `packages/support/llm-replay/tests/llm-replay.spec.ts`. +The lane itself: `pnpm run test:web` runs every scenario keylessly alongside the existing smoke pair; `DSH_SNAPSHOT=record pnpm exec vitest run --config vitest.web.config.ts apps/web/tests/` re-records a scenario's fixture against the live model; `DSH_SNAPSHOT=refresh` rewrites the aria goldens keylessly. `paceMs` validation, pacing floor, abort-during-pace, both `assertConsumed` failure shapes, and the `{ patches }` acceptance/rejection paths (index swap keeps siblings, `at == length` appends, out-of-range/non-integer loud) are pinned in `packages/support/llm-replay/tests/llm-replay.spec.ts`. ## Deferred - **Web header-class pin**: web fixtures tokenize `{{system}}`/`{{tools}}` everywhere and no scenario pins bootHost's composed prompt/tool schemas (`TODO(web-header-pin)` — the scaffold `recordFixture` JSDoc marks it).

The class-level JSDoc states the semantics every implementation owes: registrations outlive producer and surface fibers, owned access is session-fenced, settlement is first-wins with contained listeners, and `start` refuses work while no control surface is attached. +- **`@deepseek-ai/dsh-tasks-local` (implementation)** — `LocalTaskService`, the process-local registry moved verbatim: the in-memory store, per-kind counters, waiter bookkeeping, `TASK_WAIT_TIMEOUT` deadline code, owner-cleanup effects, and force-fail teardown. The `dsh-timeout` dependency moves here with it; the seam has no implementation dependencies. +- **`@deepseek-ai/dsh-tool-tasks` (consumer)** — unchanged; it injects `'tasks'` and never imports implementation types. + +Compositions load `dsh-tasks-local` where they previously loaded `dsh-tasks` (the CLI cordis.yml row, `agent-spine-demo`, test harnesses, the tool-catalog generator boot). Producer misconfiguration diagnostics ("background tasks unavailable: load …") name `dsh-tasks-local` because a deployment fixes them by loading the implementation, not the interface. Producers, `TaskKindMap` declaration merges, and the control surface keep importing `@deepseek-ai/dsh-tasks` only. + +The seam keeps the in-process contract semantics unchanged: `TaskStart.run()` still passes callbacks and exact `Agent` objects, so a durable or cross-process backend still has design work to do before it can implement this interface (identity, restart, ownership, observation). The split moves that future work out of every consumer's dependency graph; it does not pre-design the backend. + +## Alternatives considered + +**Keep the concrete service until a second backend exists (status quo).** This was the original runtime note's position: extracting an interface before a second implementation risks freezing the wrong boundary. It lost because the boundary is no longer speculative — the eight service methods and their semantics have been stable across every producer integration since introduction, they are exactly the surface `dsh-tool-tasks` and the producers already program against, and the repository convention treats swappable capabilities as three packages by default. The residual risk (a durable backend needing contract changes) is unchanged by the split: those changes would land in the seam package either way, and today they would also churn every consumer's implementation dependency. + +**Interface-only extraction inside one package (export an abstract class beside the concrete one).** Rejected because it separates nothing operationally: consumers still depend on the package that carries the implementation and its dependencies, and a replacement backend still cannot ship without the local one in its graph. The package boundary is the unit of independent evolution here. + +**Splitting `types.ts` out but leaving the service concrete.** Rejected for the same reason — the types are not the seam; `ctx.tasks` and its method contract are. Producers need the service key and semantics, not just the shapes. + +## Consequences + +Bought: the task registry now matches the repository-wide seam shape; a durable, remote, or instrumented registry is a sibling package implementing eight abstract methods, and no producer, control surface, or `TaskKindMap` extender changes when one lands. The seam README states the contract; the implementation README owns the lifecycle bookkeeping facts. The registry behavior suite (owner cleanup, settlement, waits, teardown) lives with `dsh-tasks-local`; the seam keeps a stub-subclass test pinning registration under `ctx.tasks` and single-service duplication behavior, plus the probe-based invariant suite. + +Cost: one more package (manifest, tsconfig, README, invariant companion), and compositions must name the implementation package — a boot that loads only `@deepseek-ai/dsh-tasks` gets a pending `ctx.tasks` and producers fail with the standard missing-service behavior rather than a bespoke message. The misconfiguration diagnostics naming `dsh-tasks-local` accept staleness if a different backend becomes the recommended default. diff --git a/.agents/notes/implemented/architecture/2026-07-26-task-registry-seam.zh.md b/.agents/notes/implemented/architecture/2026-07-26-task-registry-seam.zh.md new file mode 100644 index 0000000000..aa4df43b82 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-07-26-task-registry-seam.zh.md @@ -0,0 +1,35 @@ +# Agent Note: 任务注册表是一个能力 seam（`dsh-tasks` / `dsh-tasks-local`） + +Status: implemented + +[English](2026-07-26-task-registry-seam.md) | 中文 + +## 问题 + +[后台任务运行时](2026-06-20-generic-long-running-tool-runtime.md)交付时把 `TaskService` 做成了单个具体包（package）：`@deepseek-ai/dsh-tasks` 既拥有所有生产方和控制接口面向编程的 `ctx.tasks` 契约，也拥有进程内实现（内存存储、结算簿记、所有者清理 effect、拆除逻辑）。这种捆绑重新耦合了仓库[能力 seam 规则](2026-06-13-capability-seams.md)本要分离的两种变化速率：一旦替换注册表的存储或生命周期后端，被搅动的就是同一个包，而生产方（`dsh-tool-bash`、`dsh-tool-pty`、`dsh-tool-subagent`）、控制接口（`dsh-tool-tasks`）和 `TaskKindMap` 扩展方正是从这个包导入类型与 `ctx.tasks` 接口。harness 中其余每项可替换能力（bash、pty、fs、skill、subagent、web、会话持久化）都已具备接口／实现／消费方三分；任务注册表曾是仅剩的 `core` 模式例外，仅由一条 `TODO(task-service-backend)` 注释把守。 + +## 决策 + +`tasks/` 如今是一个 bash 三件套形态的三包能力家族： + +- **`@deepseek-ai/dsh-tasks`（接口）**——抽象的 `TaskService extends Service`，拥有 `ctx.tasks`、八个方法的契约（`start`、`list`、`get`、`read`、`kill`、`wait`、`onTaskDone`、`attachSurface`）、全部词汇类型（`TaskId`、`TaskKindMap`、`TaskStart`、`TaskHooks`、`TaskOutcome`、`TaskSnapshot`、`TaskRead`、`TaskDoneListener`），以及快照不变式配套插件。类级 JSDoc 陈述了每个实现都必须兑现的语义：注册的存续期长于生产方与控制接口的 fiber，有所有者的访问以会话为界，结算遵循首次结果优先且监听器错误被隔离，并且在没有附加任何控制接口时 `start` 拒绝启动工作。 +- **`@deepseek-ai/dsh-tasks-local`（实现）**——`LocalTaskService`，即原样迁移的进程内注册表：内存存储、按 kind 划分的计数器、等待方簿记、`TASK_WAIT_TIMEOUT` deadline 代码、所有者清理 effect，以及强制失败的拆除逻辑。`dsh-timeout` 依赖随之迁入此包；seam 包不含任何实现依赖。 +- **`@deepseek-ai/dsh-tool-tasks`（消费方）**——保持不变；它注入 `'tasks'`，从不导入实现类型。 + +各组合配置在原先加载 `dsh-tasks` 的位置改为加载 `dsh-tasks-local`（CLI 的 cordis.yml 配置项、`agent-spine-demo`、各测试 harness、工具目录生成器的启动流程）。生产方的配置错误诊断信息（"background tasks unavailable: load …"）点名 `dsh-tasks-local`，因为部署方修复该问题的办法是加载实现包，而非接口包。生产方、`TaskKindMap` 声明合并和控制接口仍然只导入 `@deepseek-ai/dsh-tasks`。 + +该 seam 保持进程内契约语义不变：`TaskStart.run()` 仍然传入回调和确切的 `Agent` 对象，因此持久化或跨进程后端在能实现此接口之前仍有设计工作要做（身份、重启、所有权、观察）。这次拆分把该项未来工作移出了每个消费方的依赖图；它并不预先设计后端。 + +## 曾考虑的替代方案 + +**在第二个后端出现之前保持具体服务（维持现状）。**这正是当初运行时 Agent Note 的立场：在第二种实现出现前抽取接口，可能固化错误的边界。该方案落选，因为这条边界已不再是臆测：八个服务方法及其语义自引入以来在每一次生产方集成中都保持稳定，它们正是 `dsh-tool-tasks` 与各生产方已经在面向编程的那套接口，而且仓库约定默认将可替换能力拆成三个包。剩余风险（持久化后端可能需要变更契约）不因这次拆分而改变：无论拆分与否，这类变更都会落在 seam 包里，而若维持合并包的现状，它们还会连带搅动每个消费方的实现依赖。 + +**在单个包内仅抽取接口（在具体类旁导出一个抽象类）。**否决：它在运作层面并未分离任何东西。消费方依然依赖携带实现及其依赖项的那个包，而替换后端若不把本地实现纳入依赖图，就仍然无法发布。在这里，包边界才是独立演进的单位。 + +**拆出 `types.ts` 但让服务保持具体。**基于同样的理由否决：类型并不是 seam，`ctx.tasks` 及其方法契约才是。生产方需要的是服务键和语义，而不只是类型形状。 + +## 后果 + +换来的是：任务注册表如今与全仓库统一的 seam 形态一致；持久化、远程或带插桩的注册表将是一个实现八个抽象方法的兄弟包，这样的后端落地时，任何生产方、控制接口或 `TaskKindMap` 扩展方都无需改动。seam 包的 README 陈述契约；实现包的 README 拥有生命周期簿记的相关事实。注册表行为测试套件（所有者清理、结算、等待、拆除）随 `dsh-tasks-local` 存放；seam 包保留一个基于桩子类的测试，固定 `ctx.tasks` 下的注册行为与单一服务的重复注册行为，外加基于探针的不变式测试套件。 + +代价是：多出一个包，即多一份 manifest（元数据清单）、tsconfig、README 与不变式配套插件；同时各组合配置必须点名实现包。若某次启动只加载 `@deepseek-ai/dsh-tasks`，得到的将是挂起的 `ctx.tasks`，生产方将按标准的服务缺失行为失败，而不会得到一条专门定制的消息。若推荐的默认后端日后换成其他实现，点名 `dsh-tasks-local` 的配置错误诊断信息会随之陈旧；这一代价已被接受。 diff --git a/apps/cli/cordis.yml b/apps/cli/cordis.yml index b89df77c46..1d5c37cff5 100644 --- a/apps/cli/cordis.yml +++ b/apps/cli/cordis.yml @@ -52,7 +52,7 @@ name: '@deepseek-ai/dsh-agent' - id: tasks - name: '@deepseek-ai/dsh-tasks' + name: '@deepseek-ai/dsh-tasks-local' - id: agent-loop name: '@deepseek-ai/dsh-agent-loop' diff --git a/apps/cli/package.json b/apps/cli/package.json index 8799669e8d..4f3bb5be35 100644 --- a/apps/cli/package.json +++ b/apps/cli/package.json @@ -57,7 +57,7 @@ "@deepseek-ai/dsh-subagent-fork": "workspace:^", "@deepseek-ai/dsh-subagent-spawn": "workspace:^", "@deepseek-ai/dsh-system-prompt": "workspace:^", - "@deepseek-ai/dsh-tasks": "workspace:^", + "@deepseek-ai/dsh-tasks-local": "workspace:^", "@deepseek-ai/dsh-timeout-policy": "workspace:^", "@deepseek-ai/dsh-token-meter": "workspace:^", "@deepseek-ai/dsh-tool-bash": "workspace:^", diff --git a/docs/capability-seams.md b/docs/capability-seams.md index 0f2dfd1610..2da9652c59 100644 --- a/docs/capability-seams.md +++ b/docs/capability-seams.md @@ -117,6 +117,7 @@ flowchart LR pkg_tool_ralph["tool-ralph"] pkg_tasks["tasks"] svc_tasks["ctx.tasks

Cancel: a `{ patches }` `hang` with a `readyFile` marker — the marker's existence proves the stream is parked mid-turn before the test clicks Stop, making mid-stream cancellation deterministic by construction (`turn/end` reason `aborted`, composer re-enabled). AUTH error: a pre-chunk `throw` outside llm-retry's retryable set (`turn/end` reason `error`, zero `llm/retry` events, composer recovers). SERVER retry: `throw` at call 0 + the fixture's own success appended at 1, proving llm-retry end-to-end in the browser via the durable `llm/retry` record (`request/header` logs only on change, so attempt count is invisible there). 4. **`question-composer`** — the shipped composition's resident `ask_user_question` takeover: a recorded turn blocks mid-step on the real userInteraction seam, the composer (`[data-question-key]`) renders in the browser, the test answers through it (the ONE sanctioned place a drive step reacts to model content: the turn cannot complete without the answer, in record and replay alike), and the tool result carries the chosen label. Golden: the composer's stable waiting state. 5. **`steering`** — mid-turn steer while the question composer blocks the step (the deterministic mid-turn window; no timing dependence). The composer locks while running, so the steer POSTs `session.prompt` `mode:'steer'` from the page over the same same-origin `/api` wire the client uses (`TODO(web-steer-composer)`: drive a composer gesture once one exists); everything downstream is product — gateway → `Agent.steer` → step-boundary drain → durable `steering/message` → SSE → badged interjection bubble.

Each started sub-call logs a tool/code-dispatch-start event at pool entry; the existing tool/code-dispatch settles the pair (started ⇔ settles exactly once; abandoned queued calls log neither).

The existing `tool/code-dispatch` settles the pair (same `subCallId`); every started call settles exactly once (aborts settle as `isError` outcomes through the pipeline). Timing = the two events' `time` fields. Both stay log-only; model context is untouched; format stays v0. +- **Bridge scheduler**: submitted calls are classified at submission via `registry.executionMode` (the SAME fail-closed `isConcurrencySafe` contract the loop uses) and start strictly in submission order. Consecutive parallel-classified calls overlap up to `maxParallelSubCalls` (a validated registry `Config` field, default 10 — the loop scheduler's own default; `1` restores serial dispatch); an exclusive call drains the pool, runs alone, and bars later calls. This is the loop's group semantics adapted to calls that arrive over time instead of in one parsed batch. Run settlement aborts in-flight dispatches and abandons queued-unstarted ones (binding rejection, no events), then drains to quiescence before the outer result closes the turn. +- **Client**: `CodeSubCall` widens to `RunningToolCall | ToolResultNode` — a start event lands the running shape in the dispatch index (rows derive the running ring from the shape, exactly as for native in-flight calls), and its settle replaces the entry in place, preserving start order under parallel completion and carrying the start's `time` as `callTime` (duration source). A settle with no observed start (window cut mid-pair, or a pre-start-event log) appends directly, so old logs keep rendering. +- **SDK prompt**: the model-facing "calls execute sequentially" sentence is replaced with the true contract (independent safe calls may overlap under `Promise.all`; dependent work sequences with `await`) — a model-visible change, re-recorded across every code-mode snapshot. + +## Alternatives considered + +**Unrestricted parallelism (let `Promise.all` overlap everything).** Rejected: writes could race; the native scheduler exists precisely because the tool, not the caller, owns the safety claim. One concurrency vocabulary across native and Code Mode was the settled requirement. + +**Emit the start event at submission instead of pool entry.** Rejected: a submission-time start would show queued-but-never-run calls as "running" and would force a third "abandoned" terminal event to reconcile the log. Start-at-entry keeps the invariant *started ⇔ settles exactly once* and needs no third event. + +**Reuse the loop scheduler's implementation directly.** Rejected: the loop schedules a fully-parsed batch with model-order result commitment; the bridge schedules an open-ended stream of submissions whose results return to the program (not the transcript), so only the *contract* (classification, pool, barriers) is shared, not the machinery. + +## Consequences + +Programs get native-grade latency for independent reads with no new model-side API — `Promise.all` simply works better, and prompt guidance changed accordingly. The web UI shows per-sub-call running rings live (fixture emits start/settle pairs; jsdom pins the running shape; the runtime spec pins in-place settlement, out-of-order completion, and callTime pairing).

Deterministic — lexicographic tool order, byte-identical text for an unchanged tool set (prefix-cache-friendly). The codegen (`jsonSchemaToTs`, exported) handles every unified schema construct and degrades unsupported raw constructs to `unknown`, never throwing during prompt assembly. -- **The dispatch bridge** (`run_code`'s execute): every binding call is snapshotted as lossless JSON before dispatch (`undefined`, `BigInt`, cycles, sparse arrays, `-0`, and exotic objects reject that one call), serialized through a per-run queue (even `Promise.all` executes underlying calls one at a time in submission order), given the outer execution's opaque token as `parent`, and run through the complete pre-execute → guards → execute → post-execute → result pipeline. A success returns the final canonical value after policy; a failure reaches the worker as one message and becomes `ToolCallError(toolName, message)`. Each sub-call is logged as a `tool/code-dispatch` session event with deterministic id `:code:` and the complete model-facing `content`/`isError` outcome (the `tool/result` vocabulary, so UIs render sub-calls through the native path); `deriveMessages()` does not surface that event or persist the canonical value. Token correlation lets commit-style observers defer an inner success until the final `run_code` result without exposing the live outer execution; ordinary tool side effects are not rolled back. Every sub-call `additionalContexts` entry is deferred through the outer `ToolRunContext` in dispatch order; the loop appends those contexts only after the parent `run_code` result, preserving adjacency and retaining each source/meta even when the program later fails. +- **The dispatch bridge** (`run_code`'s execute): every binding call is snapshotted as lossless JSON before dispatch (`undefined`, `BigInt`, cycles, sparse arrays, `-0`, and exotic objects reject that one call), scheduled through a per-run pool that reuses the native concurrency contract — calls start strictly in submission order, consecutive `isConcurrencySafe` calls overlap up to the validated `maxParallelSubCalls` config (default 10; `1` restores serial dispatch), and an exclusive-classified call drains the pool, runs alone, and bars later calls — given the outer execution's opaque token as `parent`, and run through the complete pre-execute → guards → execute → post-execute → result pipeline. A success returns the final canonical value after policy; a failure reaches the worker as one message and becomes `ToolCallError(toolName, message)`. Each started sub-call logs a `tool/code-dispatch-start` event (deterministic id `:code:`, numbered by submission) at pipeline entry and settles with one `tool/code-dispatch` event carrying the complete model-facing `content`/`isError` outcome (the `tool/result` vocabulary, so UIs render sub-calls through the native path — the pair's `time` fields carry per-sub-call timing); a queued call abandoned by run settlement logs neither. `deriveMessages()` surfaces neither event nor persists the canonical value. Token correlation lets commit-style observers defer an inner success until the final `run_code` result without exposing the live outer execution; ordinary tool side effects are not rolled back. Every sub-call `additionalContexts` entry is deferred through the outer `ToolRunContext` in dispatch order; the loop appends those contexts only after the parent `run_code` result, preserving adjacency and retaining each source/meta even when the program later fails. - **Settlement discipline**: the bridge owns a run-scoped abort that follows the outer signal in and fires when the run settles for any reason, so a budget expiry aborts an in-flight sub-tool instead of orphaning it; the bridge then drains its queue BEFORE returning, so every `tool/code-dispatch` lands inside the open turn. A failed run throws `CodeRunFailedError` (`code: 'CODE_RUN_FAILED'`, message = the failure kind + captured logs), which the pipeline converts to a structured `isError` the model self-corrects from. - **Result boundary**: intermediate binding values cross the worker boundary whole and have no per-binding byte cap. `run_code` returns canonical `{ logs: string[], result?: JsonValue }`; strings render raw, every other present JSON root renders through a stack-safe pretty JSON traversal whose total indentation is capped at ten characters (deeper subtrees stay compact), `null` remains explicit, and absent `result` means the program returned `undefined`. The worker's configurable `maxOutputBytes` (default 64 MiB) applies only to the combined serialized outer log-array, completion-value, or failure-message payloads; fixed result-envelope syntax and presentation whitespace are outside that ledger. Invalid and over-limit completions fail explicitly, and only this outer result is eligible for ordinary spill. ### Parallel execution -The agent loop groups consecutive `parallel` calls into a bounded rolling pool and treats each `exclusive` call as an ordering barrier.

Durable proof: the session header's cwd is the create-by-name target /workspace.

Golden: the composer's stable waiting state. 5. **`steering`** — mid-turn steer while the question composer blocks the step (the deterministic mid-turn window; no timing dependence). The composer locks while running, so the steer POSTs `session.prompt` `mode:'steer'` from the page over the same same-origin `/api` wire the client uses (`TODO(web-steer-composer)`: drive a composer gesture once one exists); everything downstream is product — gateway → `Agent.steer` → step-boundary drain → durable `steering/message` → SSE → badged interjection bubble. Record-mode fixture honesty: the recording is rejected unless the live model's final reply obeys an instruction only the steering message carries. 6. **`navigation-panes`** — one rich two-turn seed (turn 1: bash + two parallel reads in one assistant message; turn 2: a markdown-heavy reply) rendered cold through the seeded-history pattern (zero model calls), serving four surfaces: sidebar search (client-side title filter — asserted only after the durable title lands with the attach baseline, because a cold `SessionSummary` carries no title and search matches the `displayTitle` the user sees; negative query empties the tree, positive narrows, clear restores), the Trajectory tab (turn sections + the step group's tool mix plus the view-area aria golden), the Waterfall tab (span stats + one lane per span — the P-I fold counts a turn-0 prologue span because only assistant/steering nodes carry a turn number, pinned as-is), and the details column (the bash toolview row routes click to openDetails; open/closed is asserted on the frame's `data-details-collapsed` attribute because close collapses the grid column to width 0 without unmounting the subtree). +7. **`lifecycle-chrome`** — one tiny recorded text turn drives three whole-page concerns. Workspace flow over the real wire: the empty-state hero's first send materializes a real Workspace + Session (the jsdom `workspace-flow.snapshot.ts` suite pins this state machine over the fixture client; this scenario pins it through HTTP RPC + SSE + the gateway), proven durably by the session header's cwd being the create-by-name target `/workspace`, plus the hero waiting-state aria golden. Reload recovery: collapse the sidebar (persisted `dsh.layout.panels`), `page.reload`, and the surface comes back whole from persistence alone — layout collapsed, selection restored (`dsh.sessions.current`), the recorded turn re-rendered from `session.history` with zero model calls (the drained replay cursor makes any stray request fail loud at close). Dark mode: no product control flips the theme yet, so the scenario drives the ThemeService's entire DOM contract — the `body[data-ds-dark-theme]` attribute — and pins the shipped cascade: the alias token flips, a painted surface repaints, and removing the attribute restores the light sample exactly (`TODO(web-theme-gesture)` upgrades to a real settings control); per the scope ruling there is no theme/layout golden (aria is color-blind). ### CI stance diff --git a/.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.zh.md b/.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.zh.md index 3ec27956dd..9850023a49 100644 --- a/.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.zh.md +++ b/.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.zh.md @@ -48,6 +48,7 @@ Web GUI 以一条真实组装链交付——chromium 页面 → client 插件 bu 4. **`question-composer`**——已交付组合中常驻的 `ask_user_question` 接管：一段已录轮次在真实的 userInteraction seam 上阻塞于步骤中途，提问输入框（`[data-question-key]`）在浏览器中渲染，测试经它作答（这是驱动步骤对模型内容作出反应的唯一获准之处：没有这个回答，轮次无法完成，record 与 replay 皆然），工具结果携带所选的 label。预期输出：提问输入框稳定的等待态。 5. **`steering`**——在提问输入框阻塞该步骤时做轮次中途 steering（中途引导），此即确定性的轮次中途窗口，不依赖任何时序。输入框在运行期间锁定，因此这一 steer 由页面经客户端所用的同一条同源 `/api` wire POST `session.prompt` `mode:'steer'`（`TODO(web-steer-composer)`：待有输入框手势后改为驱动它）；下游的一切都是产品路径——gateway → `Agent.steer` → 步骤边界排空 → 持久的 `steering/message` → SSE → 带徽标的插话气泡。record 模式的 fixture 诚实性：除非真实模型的最终回复遵循了一条只有 steering 消息才携带的指令，否则该次录制被拒绝。 6. **`navigation-panes`**——一份内容丰富的双轮次种子（轮次 1：同一条 assistant 消息内的 bash + 两次并行 read；轮次 2：一段 markdown 密集的回复）经 seeded-history 模式冷渲染（零模型调用），承载四个表面：侧栏搜索（客户端标题过滤；仅在持久的标题随 attach 基线一同到达后才断言，因为冷的 `SessionSummary` 不携带标题，而搜索匹配的是用户所见的 `displayTitle`；反例查询清空整棵树，正例查询收窄，清除后复原）、Trajectory 标签页（轮次分节 + 步骤组的工具构成，外加视图区 aria 预期输出）、Waterfall 标签页（span 统计 + 每个 span 一条泳道；只有 assistant/steering 节点携带轮次编号，因此 P-I 折叠会将一个轮次 0 的序幕 span 计入，按原样钉住）与详情列（bash 工具视图行把点击路由到 openDetails；打开/关闭状态断言在 frame 的 `data-details-collapsed` 属性上，因为关闭把网格列收缩到宽度 0 而不卸载子树）。 +7. **`lifecycle-chrome`**——一段极小的已录纯文本轮次驱动三个整页关注点。真实 wire 上的 Workspace 动线：空态 hero 的首次发送物化出真实的 Workspace + Session（jsdom 的 `workspace-flow.snapshot.ts` 套件基于 fixture 客户端钉住这一状态机；本场景则经 HTTP RPC + SSE + gateway 钉住它），其持久证据是会话头部的 cwd 恰为按名创建的目标 `/workspace`，外加 hero 等待态的 aria 预期输出。重新加载恢复：折叠侧栏（持久化于 `dsh.layout.panels`），`page.reload`，整个表面纯凭持久化完整归来——布局保持折叠，选中项恢复（`dsh.sessions.current`），已录轮次从 `session.history` 重新渲染且零模型调用（已耗尽的回放游标使任何离群请求都在 close 时大声失败）。暗色模式：产品尚无任何控件能切换主题，因此本场景驱动 ThemeService 的整个 DOM 契约（即 `body[data-ds-dark-theme]` 属性），并钉住已交付的级联：alias token 翻转，某个实际绘制的表面重绘，移除该属性则精确还原亮色采样值（`TODO(web-theme-gesture)`：待有真实设置控件后升级为驱动它）；按范围裁定，主题/布局不设预期输出（aria 感知不到颜色）。 ### CI 立场 diff --git a/apps/web/tests/lifecycle-chrome.e2e.ts b/apps/web/tests/lifecycle-chrome.e2e.ts new file mode 100644 index 0000000000..2ab4f5aeea --- /dev/null +++ b/apps/web/tests/lifecycle-chrome.e2e.ts @@ -0,0 +1,152 @@ +// Web e2e scenarios: lifecycle & chrome — the workspace-aware first-send +// flow over the real wire, reload recovery, and the dark-mode token cascade. +// One tiny recorded turn (text-only) drives the whole spec: the empty-state +// hero materializes a real Workspace + Session on first send (the jsdom +// workspace-flow suite pins the object-layer state machine over the fixture +// client; THIS spec pins the same flow through HTTP RPC + SSE + the host +// gateway), reload replays everything from the log (zero further model +// calls), and the theme scenario proves the shipped dark palette actually +// cascades: attribute -> alias token flip -> painted surface change.

SDK.\n\nYou are headless-agent, a coding assistant powered by the deepseek-v4-flash model. Your working directory is /tmp/advanced-headless.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Calls execute sequentially, even under `Promise.all`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n /** Execute a bash command (`bash -c`) and return its stdout/stderr. Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available.

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n cordis_mount: {\n /** Body of an async JS function; must `return` the plugin to mount. */\n code: string;\n } & Record;\n /** Dispose a plugin previously mounted with cordis_mount, by id.

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

Your working directory is /tmp/advanced-headless.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results.

Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Calls execute sequentially, even under `Promise.all`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n /** Execute a bash command (`bash -c`) and return its stdout/stderr.

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n cordis_mount: {\n /** Body of an async JS function; must `return` the plugin to mount. */\n code: string;\n } & Record;\n /** Dispose a plugin previously mounted with cordis_mount, by id.

Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"Body of an async JS function; must `return` the plugin to mount."}},"required":["code"]}},{"name":"cordis_unmount","description":"Dispose a plugin previously mounted with cordis_mount, by id.

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

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New tools/code-dispatch-log waterfall (run via registry.shapeDispatchLog, contained — a throwing listener falls back to the unshaped content) lets listeners reshape the tool/code-dispatch event's content before the bridge appends it. dsh-spill-policy registers a second arm sharing the model-facing arm's exact replacement pipeline (same maxInlineBytes cap, preview + locator, within-cap invariant, best-effort fallbacks), with artifacts labeled dispatch under the sub-call id. The program's value is untouched; read sub-calls ARE bounded (a log copy is not model context, and read produces the biggest logs). Resolves the tools README's uncapped-dispatch-log Known Limitation. --- ...26-07-26-code-dispatch-log-spill.i18n.yaml | 6 + .../2026-07-26-code-dispatch-log-spill.md | 31 ++++ .../2026-07-26-code-dispatch-log-spill.zh.md | 31 ++++ docs/config-catalog.md | 12 +- docs/core-data-structures/tools.i18n.yaml | 4 +- docs/core-data-structures/tools.md | 26 +++ docs/core-data-structures/tools.zh.md | 26 +++ docs/event-producer-consumer.md | 5 +- .../core/scope/src/scoped-events.generated.ts | 1 + packages/core/tools/README.md | 2 +- packages/core/tools/src/code-mode.ts | 36 ++-- packages/core/tools/src/index.ts | 55 ++++++ packages/spill/spill-policy/README.md | 4 +- packages/spill/spill-policy/src/index.ts | 159 ++++++++++++------ .../spill-policy/tests/spill-policy.spec.ts | 91 ++++++++++ scripts/gen-cordis-catalog.ts | 1 + 16 files changed, 415 insertions(+), 75 deletions(-) create mode 100644 .agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.i18n.yaml create mode 100644 .agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.md create mode 100644 .agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.zh.md diff --git a/.agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.i18n.yaml b/.agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.i18n.yaml new file mode 100644 index 0000000000..f00ecd5d2a --- /dev/null +++ b/.agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

The [host foundation note](2026-07-26-code-dispatch-ui-foundation.md) accepted the unbounded log deliberately and named this PR as the payoff point; the [live-parallel note](2026-07-26-code-mode-live-parallel-dispatch.md) settled the event pair this shaping hooks into. + +## Problem + +Since the full-content dispatch logging landed, a `run_code` program that reads a large file wrote the complete rendered text into the session log — uncapped and outside spill policy, while native results were bounded to `maxInlineBytes` before logging.

The payload (`CodeDispatchLog`) carries the outer execution, the hoisted `agent` routing key, the sub-call identity, and the default content. Only the durable copy is shapeable — the program already received the complete value across the worker boundary, and the model sees neither. +- **Policy**: `dsh-spill-policy` registers a second arm on the new seam sharing the exact replacement pipeline of its model-facing arm (same `maxInlineBytes` cap, same preview + locator + within-cap invariant, same best-effort fallbacks), with the artifact labeled `dispatch` under the sub-call id. UIs and replay read the full text through the spill artifact exactly as they do for spilled native results, so the native-parity rendering story survives bounding. +- **One deliberate asymmetry**: the model-facing arm skips `read` (the `read → spill → read again` loop); the dispatch-log arm bounds `read` sub-calls too — a log copy is not model context, so the loop cannot happen, and `read` is precisely the tool that produces huge logs. + +## Alternatives considered + +**Bound inside the bridge with a plain cap (no spill).** Rejected: truncation without a locator loses data replay/UIs may need, and re-introduces the "truncated summary" degraded render path the stack removed. + +**Spill inside the bridge directly (call `ctx.spillStore` from code-mode.ts).** Rejected: the registry would grow a hard dependency on the spill capability; the waterfall keeps the policy where every other spill decision lives, composable and disable-able (omitted `maxInlineBytes` still means a true no-op). + +**Reuse `tools/post-execute` for nested calls instead of a new event.** Rejected: post-execute shapes the PROGRAM-facing result (nested calls deliberately skip it so programs get complete data); the durable copy needs its own decision point after the program has its value. + +## Consequences + +The session log is bounded again for Code Mode turns — the README's Known Limitations entry about uncapped dispatch logging is resolved and now points here. Old logs with oversized dispatch content still replay (the event shape is unchanged; only future appends shrink). The web UI renders spilled sub-call output as the preview + locator text through the identical native path, no special casing. diff --git a/.agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.zh.md b/.agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.zh.md new file mode 100644 index 0000000000..e084ae80d7 --- /dev/null +++ b/.agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.zh.md @@ -0,0 +1,31 @@ +# Agent Note：将 Code Mode 子分发结果的持久副本纳入 spill 机制 + +Status: implemented + +[English](2026-07-26-code-dispatch-log-spill.md) | 中文 + +> 范围：Code Mode UI 堆叠 PR（Pull Request）链的第四个 PR，即用既有的 spill 机制为 `tool/code-dispatch` 事件的内容施加边界。[宿主侧基础 Agent Note](2026-07-26-code-dispatch-ui-foundation.md)当初有意接受了不设上限的日志，并指明本 PR 就是兑现点；[实时并行 Agent Note](2026-07-26-code-mode-live-parallel-dispatch.md)敲定了本次整形所挂接的事件对。 + +## 问题 + +自携带完整内容的分发日志落地以来，读取大文件的 `run_code` 程序过去会把完整的渲染文本写进会话日志，不设上限、位于 spill 策略之外；而原生结果在记录之前就已被限制在 `maxInlineBytes` 以内。这种不对称的方向完全反了：子调用（本就为批量数据工作而设计）恰恰是最可能携带巨大结果的调用，而每个这样的轮次都会让 JSONL 增长数 MB。 + +## 决策 + +**在注册表上增设一个日志整形 waterfall（瀑布式事件），spill 策略作为其第一个监听器。** + +- **Seam**：`tools/code-dispatch-log`，一个按作用域过滤的 waterfall，由桥接层在追加 `tool/code-dispatch` 之前对每个已结算的子分发运行（经由 `registry.shapeDispatchLog`，且故障被兜住：监听器抛出异常时回退到未整形的内容）。载荷（`CodeDispatchLog`）携带外层执行、提升出来的 `agent` 路由键、子调用标识与默认内容。可整形的只有持久副本：程序已经跨 worker 边界收到了完整的值，而模型两者都看不到。 +- **策略**：`dsh-spill-policy` 在新 seam 上注册第二个分支，与其面向模型的分支共用一模一样的替换流水线（同样的 `maxInlineBytes` 上限、同样的预览 + 定位符 + 不超上限不变式、同样的尽力而为回退），产物以 `dispatch` 为标签，记在子调用 id 名下。UI 与回放通过 spill 产物读取全文，方式与读取被 spill 的原生结果完全相同，因此与原生同等保真的渲染在施加边界之后依然成立。 +- **一处有意的不对称**：面向模型的分支跳过 `read`（避免 `read → spill → read again` 循环）；分发日志分支则连 `read` 子调用也施加边界：日志副本不是模型上下文，该循环因此不可能发生，而 `read` 恰恰是会产生巨大日志的那个工具。 + +## 曾考虑的替代方案 + +**在桥接层内部用普通上限施加边界（不做 spill）。** 否决：没有定位符的截断会丢失回放与 UI 可能需要的数据，还会重新引入本堆叠 PR 链已经移除的「截断摘要」降级渲染路径。 + +**直接在桥接层内做 spill（从 code-mode.ts 调用 `ctx.spillStore`）。** 否决：注册表会因此对 spill 能力产生硬依赖；waterfall 则把策略留在所有其他 spill 决策所在的地方，既可组合也可禁用（省略 `maxInlineBytes` 依然意味着真正的 no-op）。 + +**让嵌套调用复用 `tools/post-execute`，而不是新增一个事件。** 否决：post-execute 整形的是面向程序的那份结果（嵌套调用有意跳过它，好让程序拿到完整数据）；持久副本需要一个属于自己的决策点，位于程序取得其值之后。 + +## 后果 + +对 Code Mode 轮次而言，会话日志重新有了边界：README 中关于分发日志不设上限的 Known Limitations 条目已经解决，现在指向本篇。携带超大分发内容的旧日志仍可回放（事件形状未变；只有今后的追加才会变小）。web UI 经由与原生完全相同的路径，把被 spill 的子调用输出渲染为预览 + 定位符文本，没有任何特殊处理。 diff --git a/docs/config-catalog.md b/docs/config-catalog.md index 51f57f7bde..eeaed0302a 100644 --- a/docs/config-catalog.md +++ b/docs/config-catalog.md @@ -1202,7 +1202,7 @@ export interface Config { } ``` -Source: [`packages/spill/spill-policy/src/index.ts:51`](../packages/spill/spill-policy/src/index.ts) +Source: [`packages/spill/spill-policy/src/index.ts:60`](../packages/spill/spill-policy/src/index.ts) ## `@deepseek-ai/dsh-storage-domain` @@ -1704,13 +1704,21 @@ export interface Config { * absent or mismatched.

Fifth PR of the Code Mode UI stack; the [chat sub-call rows note](../feature/2026-07-26-code-mode-chat-subcall-rows.md) shipped the `run_code` program body this exists to make readable. Styling ground rules are owned by [the web styling ruling](2026-07-19-web-styling-system.md). + +## Problem + +The client rendered every code surface — markdown fences in assistant prose, the `run_code` program body, the details panel's args — as flat monospace text. The stack's primary payload is model-written TypeScript; unhighlighted programs are measurably harder to scan, and the repo already ships shiki-highlighted code on its VitePress site, so the web app was the one code-rendering surface without it. + +## Decision + +**Shiki in its synchronous fine-grained form, as one `ui-primitives` singleton, themed exclusively through CSS custom properties.** + +- **Dependency**: `shiki/core` + `@shikijs/langs`, composed via `createHighlighterCoreSync` with `createJavaScriptRegexEngine({ forgiving: true })` — no oniguruma WASM, no async init, bundle-friendly. Grammar allowlist: `typescript` (embeds JS), `shellscript`, `json` — the languages the harness actually renders; everything else falls back to a geometry-identical plain block, never an error. Prior art: the VitePress site already renders all documentation code through shiki, and TextMate grammars materially beat regex highlighters on TypeScript — the payload that matters here. +- **Singleton**: `ui-primitives/src/markdown/highlight.ts` lazily creates one `HighlighterCore` per document and exposes `highlightToHtml(code, lang)` (undefined = render plain). The shared `CodeBlock` component owns both arms; its shiki arm injects the generated span tree via `dangerouslySetInnerHTML` — sanctioned because shiki emits a static span tree computed from the code text (no user HTML passes through, no scripts/handlers), shiki's own documented consumption path. +- **Theming**: shiki's `createCssVariablesTheme` routes every token color through `--shiki-*` custom properties; the VALUES live in a new `ui-theme/styles/shiki.css` token sheet (light on `:root`, dark on `body[data-ds-dark-theme]` — the same cascade as every other sheet), imported by the shell's `base.css` chain. Component CSS stays tokens-only; no literal color ever enters JS or component sheets. Background/foreground alias the existing markdown code-block tokens so highlighted and plain blocks agree. +- **Surfaces**: markdown fences (`MarkdownText`'s `pre` component routes single-string fences through `CodeBlock`), the `run_code` expanded program body (ToolRow's code variant, `lang="typescript"`), and the details panel's Input args (`lang="json"`). Output stays plain deliberately — tool output is arbitrary text, and guessing a grammar would mis-highlight more than it helps. + +## Alternatives considered + +**`rehype-highlight`/lowlight.** Runner-up: naturally sync and ~⅓ the bundle, but regex-grammar fidelity on TypeScript is visibly worse, and the repo would then run two highlighter systems (site: shiki, app: highlight.js) with two theming vocabularies. + +**Full `shiki` bundle or the oniguruma WASM engine.** Rejected: the full bundle ships every grammar/theme; WASM needs async loading the sync client boot deliberately avoids. The fine-grained core with three grammars keeps the cost proportional to actual use. + +**Highlight in a worker / async.** Rejected: the payloads are small (programs, fences, args); the synchronous JS engine tokenizes them in microseconds, and async introduces a flash-of-unhighlighted-code plus render-machinery churn for no measured need. + +## Consequences + +One code surface for every consumer — a future surface imports `CodeBlock` and inherits highlighting, theming, and the plain fallback. The bundle grows by the shiki core + three grammars (paid once in `ui-primitives`). Token colors are the first `--shiki-*` sheet; a theme package registering alias overrides extends them like any other token. jsdom specs pin the token-span structure, alias resolution, both fallback arms, and the fence route; the existing built-bundle snapshot and browser e2e cover the assembled path. diff --git a/apps/web/tests/code-mode-fixture.snapshot.ts b/apps/web/tests/code-mode-fixture.snapshot.ts index e862474348..5abf8bc6c0 100644 --- a/apps/web/tests/code-mode-fixture.snapshot.ts +++ b/apps/web/tests/code-mode-fixture.snapshot.ts @@ -139,13 +139,20 @@ it('expands the code row into the program body and resolves a sub-row through th boot() await openFixtureSession() - // Expand: the leading control reveals the program verbatim. + // Expand: the leading control reveals the program (shiki-tokenized: the + // text splits into styled spans inside one

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

ds-review-bot findings: the packaged Python runtime smoke's scripted
run_code call gains the required description; the ToolDefinition JSDoc
and the Code Mode foundation note (both languages, pair re-recorded) now
state both required parameters; the cordis-dynamic-toolchain fixture's
request/header line is re-compacted so the header-scrub hygiene guard
passes (my earlier patch had re-spaced it). The TUI terminal fixture was
already regenerated from keyless replay in the previous commit.

 ### The run_code tool and the dispatch bridge
 
-Under `'code'` and `'both'` the registry owns `run_code` as a reserved presentation transport with one required parameter, `{ code: string }`. It is represented by a normal `ToolDefinition` for dispatch but stays outside the filterable capability layers, so restrictions cannot accidentally remove Code Mode's only entry point. Calls traverse the complete tool pipeline — `tools/pre-execute` → monotonic guards → `tools/execute` around dispatch → `tools/post-execute` → optional definition-owned `finalizeContent` → immutable `tools/result` notification — exactly like native calls; a permission plugin can inspect the program text before it runs, and final-result observers see the normalized outer outcome. Its `execute(args, exec)`:
+Under `'code'` and `'both'` the registry owns `run_code` as a reserved presentation transport with two required parameters, `{ code: string; description: string }` (the description labels the call in UIs, the bash precedent). It is represented by a normal `ToolDefinition` for dispatch but stays outside the filterable capability layers, so restrictions cannot accidentally remove Code Mode's only entry point. Calls traverse the complete tool pipeline — `tools/pre-execute` → monotonic guards → `tools/execute` around dispatch → `tools/post-execute` → optional definition-owned `finalizeContent` → immutable `tools/result` notification — exactly like native calls; a permission plugin can inspect the program text before it runs, and final-result observers see the normalized outer outcome. Its `execute(args, exec)`:
 
 1. **Build bindings.** One run-scoped signal follows outer cancellation and is aborted whenever the run settles. Each visible tool binding snapshots lossless-JSON arguments, waits on the serialization queue, executes with a deterministic call id and the outer token as `parent`, defers returned contexts through the outer execution, and logs `tool/code-dispatch` with the full rendered result content. Success returns the tool's final canonical JSON value; failure becomes the program-visible `ToolCallError`. Every sub-call retains its own immutable execution identity and traverses the full tool pipeline.
 2. **Runs the program**: `ctx.codeRuntime.run({ program: args.code, bindings: [{ global: 'tools', functions }], signal: runController.signal })`. The runtime receives the run-scoped signal, not only the caller's outer signal, so any way the outer run settles also aborts work inside the runtime.

 1. **构建绑定。** 一个 run 级别的 signal 跟随外层取消，并在 run 结算时被 abort。每个可见工具绑定都会对无损 JSON 参数创建快照，等待序列化队列，以确定性的 call id 和外层 token 作为 `parent` 执行，通过外层 execution 延后返回的上下文，并连同完整渲染后的结果内容记录 `tool/code-dispatch`。成功时返回工具最终的规范 JSON 值；失败则变为程序可见的 `ToolCallError`。每个子调用保留自己不可变的执行标识，并遍历完整的工具流水线。
 2. **运行程序**：`ctx.codeRuntime.run({ program: args.code, bindings: [{ global: 'tools', functions }], signal: runController.signal })`。运行时接收的是 run 级别的 signal 而非仅调用方的外层 signal，因此外层 run 以任何方式结算都会同时 abort 运行时内部的工作。

ds-review-bot findings on the parallel bridge: sub-dispatches now run
through the registry's staged scheduler view (the loop's own seam) —
ordered prepare (pre-execute/guards) at submission-ordered start time,
only the dispatch/body stage overlapping, and a head-of-line commit
cursor running post-execute, context deferral, and the settle event in
submission order (new spec pins post order + context order under
out-of-order completion). Queued dispatches reclassify via
executionMode() immediately before starting, so a registry mutation
while queued flips them exclusive (native lazy-reclassification
semantics). Config and tool catalogs regenerated; the tool-catalog
metadata now names the start/settle pair and the scheduling contract.

 `SessionsService.create` accepts an optional caller-preallocated SessionId. It throws `SessionCreateError` on failure: `requestedSessionId` remains available after transport uncertainty, while `publishedSessionId` is set when `workspace-attach-failed` proves the Host published a real Session before attachment failed. For the New Session flow, the frontend Session object owns its retained prompt and advances it through attachment and send; a partially published Session keeps the same object and prompt while it appears as Ungrouped.
 
+## Code Mode sub-dispatch index

+`ConversationSnapshot.codeDispatches` groups a `run_code` call's sub-dispatches under their parent callId, in start order, using the native call-block shapes: a started-but-unsettled sub-call is a `RunningToolCall` (rows derive the running ring from the shape) and its `tool/code-dispatch` settlement replaces it in place with the `ToolResultNode` form, `callTime` carrying the paired start's time. Live mux frames and history replay build the identical index; sub-calls never join the surface `nodes` flow; per-parent array and map references are memo-stable across unrelated snapshot swaps.

 ## Session title projection
 
 `SessionManager` retains the latest validated `session/title` control snapshot independently of list and session-instance arrival. Newer event seqs replace older snapshots, title timestamps contribute to list recency, and a subscription baseline discards any retained title beyond its `lastSeq` before the optional folded title arrives. Explicit session removal also clears the retained title. The client-facing `SessionSummary.title` is therefore only the actual durable title; `displayTitle` is always present and falls back through the cwd basename and session id. A cold persisted session keeps that fallback until opening or resuming it causes the host to fold and project its log-backed title.

 The view ring IS a slot: the conversation registration declares the `'conversation.view'` list slot (session scope) in its `children` table, ConversationRoot renders the active entry through its renderSlot share (`only: `), and view tabs project from the ring ledger's registration options (`id`/`order`/`label`). The chat view is this package's own ring entry; other plugins (ui-trajectory) contribute tabs through plain `ctx.slots.register` — the former package-local view registry (`registerView`/`ViewEntry`/`ConversationViewMap` and the chrome attachment table) is retired, with per-view chrome dissolved into the view components themselves.

+Generic tool rows classify the built-in bash, read, search, write, edit, and run_code names into dedicated visual variants. The filesystem variants render the edit icon and `Write · ` or `Edit · ` summary while retaining the shared row-to-details interaction. The code variant summarizes with the model-authored `description` and expands to the program itself; its logged sub-dispatches render as always-visible nested rows through the SAME keyed toolview hole (custom registrations and the GenericToolCard fallback apply to sub-rows unchanged), and the details panel resolves a selected sub-call id to its full logged args and complete output.
 
 Tool rows are slots too — the standalone tool ring (`ToolViewRegistry`/`ctx.toolviews`/outlet) is retired. The chat entry declares the keyed `'conversation.chat.toolview'` hole (session scope; the key space is runtime-open); its render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`. The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openDetails`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar). Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders).

ds-review-bot finding: awaiting shapeDispatchLog before resolving the
binding let a slow spill backend delay the program and occupy a
dispatch slot. The settle now resolves the program immediately; the
shaped append runs as tracked side work (logWork) drained at run
settlement, so every tool/code-dispatch event still lands inside the
open turn. New spec pins the contract: with a hung spill backend the
second dispatch starts and the program completes both calls, and both
settle events land once released.

Subject: [PATCH 30/64] feat(web): Code Mode sub-calls in the trajectory and
 waterfall views
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Trajectory: the layout fold interleaves one subtool cell per sub-dispatch
after its parent Tool cell (assistant-block calls, orphan results, and
running calls alike), indexes sequential across the interleave; settled
durations come from the start/settle pair, running sub-calls show the
em dash. New Sub tag (business tint) + 28px indent.

Waterfall: deriveSubSpans folds the dispatch index into per-turn lanes
with REAL wall time — each parent's window is first start → last settle
and every lane's offset/width is its fraction of it, so parallel
sub-calls visibly overlap; running lanes extend to the window end at
reduced opacity. Lanes draw under the owning turn row.

Both views read codeDispatches through the standard snapshot hook; no
new wire data, replay renders identically to live. Specs pin interleave
order, durations, the running arms, window fractions, and the rendered
lane.

+# Agent Note: Code Mode sub-calls in the trajectory and waterfall views
+
+Status: implemented
+
+English | [中文](2026-07-26-code-mode-trajectory-waterfall-spans.zh.md)
+
+> Scope: the final PR of the Code Mode UI stack — sub-dispatch rendering in the two non-chat views. Chat nesting is owned by the [sub-call rows note](2026-07-26-code-mode-chat-subcall-rows.md); the timing this consumes is the [live-parallel note](2026-07-26-code-mode-live-parallel-dispatch.md)'s start/settle pair.
+
+## Problem
+
+Trajectory and waterfall still rendered a `run_code` turn as one opaque Tool cell / one node-count bar. The chat view got nested sub-rows in the earlier PRs, but the two analytical views — whose whole purpose is structure and timing — showed none of the sub-call structure and none of the per-sub-call wall time the dispatch pair now records. Waterfall sub-spans were deliberately deferred until that pair existed: a span without real timing would have been a lie.
+
+## Decision
+
+**Trajectory: `subtool` cells interleaved after their parent Tool cell. Waterfall: real-time sub-lanes under the owning turn row.**
+
+- **Trajectory**: the layout fold takes the snapshot's `codeDispatches` index; after each Tool cell whose `callId` has dispatches (assistant-block calls, orphan results, and running calls alike), it interleaves one `subtool` cell per sub-dispatch in start order — indexes stay sequential across the interleave. A settled sub-call's duration is its start/settle pair (`durationSeconds(sub.time, sub.callTime)`); a running one shows the em dash, exactly the native in-flight convention. The new cell kind wears a `Sub` tag (business tint) and a 28px indent so nesting reads at a glance.
+- **Waterfall**: `deriveSubSpans` folds the dispatch index into per-turn lanes with REAL timing — each parent's dispatch window is first start → last settle, and every lane's offset/width is its fraction of that window, so parallel sub-calls (PR3) visibly overlap. Running lanes extend to the window end at reduced opacity with a null duration. Lanes draw under the owning turn's bar row, scaled into a fixed lane budget.
+- Both views read `codeDispatches` through the standard snapshot hook — no new wire data, no new stores; replay renders identically to live by construction.
+
+## Alternatives considered
+
+**Fold sub-calls into the turn-span node counts (weight the existing bars).** Rejected: it hides exactly the structure this stack exists to show, and node-count weighting is already flagged as a stand-in (deviation ledger #3).
+
+**A dedicated sub-call panel instead of in-view nesting.** Rejected: the stack's settled UX is nesting under the parent everywhere; a separate panel would diverge from chat and double the selection plumbing.
+
+**Defer waterfall lanes until the P-III duration-lane redesign.** Rejected: the sub-lane timing is real today (the pair), and the fraction-of-window rendering is independent of whatever the turn-level lanes become; deferring would strand the stack's timing payoff.
+
+## Consequences
+
+The waterfall carries the first REAL wall-time rendering in the client (turn bars remain node-count stand-ins — the contrast is deliberate and labeled by hover titles). Trajectory cell indexes now count sub-calls, so `#N` totals grow on Code Mode turns. Specs pin the interleave order and durations, the running em-dash arm, window fractions (offsets/widths), the running-lane extension, and the rendered lane under the turn row.

+> 范围：Code Mode UI 堆叠 PR（Pull Request）链的最后一个 PR，涵盖两个非 chat 视图中的子分发渲染。chat 的嵌套归[子调用行 Agent Note](2026-07-26-code-mode-chat-subcall-rows.md)所有；本篇所消费的计时即[实时并行 Agent Note](2026-07-26-code-mode-live-parallel-dispatch.md)的 start/settle 事件对。
+
+## 问题
+
+trajectory 过去仍把一个 `run_code` 轮次渲染为单个不透明的 Tool 单元格，waterfall 则渲染为一根节点计数条。chat 视图在此前的几个 PR 中已获得嵌套子行，但这两个分析视图（其全部意义恰恰是结构与计时）过去既不显示任何子调用结构，也不显示分发事件对如今已记录的逐子调用墙钟时间。waterfall 的子调用 span 曾被刻意推迟到该事件对存在之后：没有真实计时的 span 就是在撒谎。
+
+## 决策
+
+**trajectory：`subtool` 单元格穿插在其父 Tool 单元格之后。waterfall：所属轮次行之下、带真实计时的子泳道（sub-lane）。**
+
+- **trajectory**：布局 fold 接收快照的 `codeDispatches` 索引；凡某个 Tool 单元格的 `callId` 名下存在分发（assistant 块内的调用、孤儿结果与运行中的调用一视同仁），fold 就在该单元格之后按启动顺序为每个子分发穿插一个 `subtool` 单元格，索引在整个穿插序列中保持连续编号。已结算子调用的耗时来自其 start/settle 事件对（`durationSeconds(sub.time, sub.callTime)`）；运行中的子调用则显示破折号，与原生的进行中约定完全一致。新增的单元格类型带有 `Sub` 标签（business 色调）与 28px 缩进，嵌套关系一眼可辨。
+- **waterfall**：`deriveSubSpans` 把分发索引折叠成带真实计时的逐轮次泳道：每个父调用的分发窗口为首个 start → 最后一个 settle，每条泳道的偏移/宽度即其在该窗口中的占比，因此并行的子调用（PR3）会肉眼可见地重叠。运行中的泳道以较低的不透明度延伸至窗口末端，耗时为 null。泳道绘制在所属轮次的条形行之下，并缩放进固定的泳道预算。
+- 两个视图都经由标准的快照 hook 读取 `codeDispatches`：没有新的 wire 数据，也没有新的 store；回放的渲染由构造保证与实时完全一致。
+
+## 曾考虑的替代方案
+
+**把子调用折入轮次 span 的节点计数（给既有的条加权）。** 否决：它隐藏的恰恰是本堆叠 PR 链存在就是为了展示的结构，而且节点计数加权本就已被标记为占位（偏差账本 #3）。
+
+**用专用的子调用面板取代视图内嵌套。** 否决：本堆叠 PR 链已敲定的 UX 是处处嵌套在父级之下；独立面板会与 chat 发生偏差，还会让选中接线翻倍。
+
+**把 waterfall 泳道推迟到 P-III 的时长泳道重新设计。** 否决：子泳道的计时如今已是真实的（即那对事件），而按窗口占比的渲染与轮次级泳道将来的形态无关；推迟只会让本堆叠 PR 链的计时收益搁浅。
+
+## 后果
+
+waterfall 承载了 client 中第一处真实的墙钟时间渲染（轮次条仍是节点计数的占位；这一反差是有意为之，并由悬停标题标注）。trajectory 的单元格索引现在会把子调用计入，因此 Code Mode 轮次上的 `#N` 总数会随之增大。spec 锁定穿插顺序与耗时、运行中的破折号分支、窗口占比（偏移/宽度）、运行中泳道的延伸，以及轮次行之下实际渲染出的泳道。

Subject: [PATCH 31/64] docs: regenerate catalogs and register CodeDispatchLog
 type-equiv on the stacked tree

The static CI gates run per-branch on the merged tree: regen the cordis
catalog/api, config, persistence, and doc-graph outputs that PR3/PR4's
source changes shifted, and add the CodeDispatchLog manifest entries for
the tools.md pair's new type-equiv block.

Subject: [PATCH 32/64] test(snapshots): refresh code/both-mode fixtures
 against the replay model pins

The re-records for the SDK-prompt change had harvested live v4-pro

 - Call tools as `await tools.name(args)` — quoted access for exotic names: `tools["my-tool"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.
 - A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.
-- Calls execute sequentially, even under `Promise.all`.
+- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.
 - Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.

Your working directory is /tmp/advanced-headless.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers.

You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work.

Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Calls execute sequentially, even under `Promise.all`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under  mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available.

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** Body of an async JS function; must `return` the plugin to mount. */\n    code: string;\n  } & Record;\n  /** Dispose a plugin previously mounted with cordis_mount, by id.

Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes. */\n  workflow: {\n    /** The plain-JS workflow script body (top-level await allowed; NO `export const meta` statement; end with `return `). */\n    script: string;\n    /** The workflow identity block (plain JSON — never code). */\n    meta: {\n      /** Short kebab-case workflow name. */\n      name: string;\n      /** One-line description of what the workflow does. */\n      description: string;\n      /** Optional guidance on when this workflow applies. */\n      whenToUse?: string;\n      /** Optional phase declarations matched by phase() calls. */\n      phases?: ({\n        /** The phase title phase() calls match by exact string. */\n        title: string;\n        /** Optional one-line description of the phase. */\n        detail?: string;\n        /** Optional provider override this phase is expected to use. */\n        provider?: string;\n        /** Optional model override this phase is expected to use. */\n        model?: string;\n      } & Record)[];\n    } & Record;\n    /** Optional JSON input exposed to the script as the `args` global (wrap a bare list as a field, e.g. {\"files\": [...]}). */\n    args?: Record;\n  } & Record;\n  /** Create or fully replace a UTF-8 text file. */\n  write: {\n    /** Path to write, resolved by the filesystem backend. */\n    file_path: string;\n    /** Full UTF-8 text content to write. */\n    content: string;\n  } & Record;\n}\n\ninterface ToolOutputMap {\n  bash: {\n    kind: \"background\";\n    taskId: string;\n  } | {\n    kind: \"foreground\";\n    exitCode: number | null;\n    signal: string | null;\n    timedOut: boolean;\n    aborted: boolean;\n    timeoutMs: number;\n    stdout: {\n      text: string;\n      truncated: boolean;\n      spillPath?: string;\n    };\n    stderr: {\n      text: string;\n      truncated: boolean;\n      spillPath?: string;\n    };\n    sandbox?: {\n      mode: string;\n      denied: boolean;\n      enforcement?: string;\n      runnerFailed?: boolean;\n    };\n  };\n  cordis_inspect: string;\n  cordis_mount: {\n    id: string;\n    pluginName: string;\n    state: \"pending\" | \"loading\" | \"active\" | \"failed\" | \"disposed\" | \"unloading\";\n    provides: string[];\n    waitingFor: string[];\n  };\n  cordis_unmount: {\n    id: string;\n    pluginName: string;\n  };\n  edit: {\n    path: string;\n    before: string;\n    after: string;\n  };\n  ralph: {\n    runId: string;\n    agentsStarted: number;\n    result: JsonValue;\n  };\n  read: {\n    path: string;\n    offset: number;\n    lines: {\n      number: number;\n      text: string;\n    }[];\n    totalLines: number;\n  };\n  skill: {\n    name: string;\n    provider: string;\n    resourceBase?: {\n      kind: \"directory\";\n      path: string;\n    } | {\n      kind: \"url\";\n      url: string;\n    } | {\n      kind: \"opaque\";\n      description: string;\n    };\n    content: string;\n  };\n  subagent: {\n    kind: \"background\";\n    taskId: string;\n  } | {\n    kind: \"foreground\";\n    runId: string;\n    output: JsonValue[];\n  };\n  subagent_fork: {\n    kind: \"background\";\n    taskId: string;\n  } | {\n    kind: \"foreground\";\n    runId: string;\n    output: JsonValue[];\n  };\n  task_kill: {\n    outcome: \"cancellation-requested\" | \"already-finished\";\n    task: {\n      id: string;\n      kind: string;\n      label: string;\n      status: \"running\" | \"stopping\" | \"completed\" | \"killed\" | \"failed\";\n      detail?: string;\n      startedAt: number;\n      finishedAt?: number;\n    };\n  };\n  task_list: ({\n    id: string;\n    kind: string;\n    label: string;\n    status: \"running\" | \"stopping\" | \"completed\" | \"killed\" | \"failed\";\n    detail?: string;\n    startedAt: number;\n    finishedAt?: number;\n  })[];\n  task_output: {\n    text: string;\n    task: {\n      id: string;\n      kind: string;\n      label: string;\n      status: \"running\" | \"stopping\" | \"completed\" | \"killed\" | \"failed\";\n      detail?: string;\n      startedAt: number;\n      finishedAt?: number;\n    };\n  };\n  todo_write: {\n    todos: ({\n      content: string;\n      status: \"pending\" | \"in_progress\" | \"completed\";\n    })[];\n    counts: {\n      pending: number;\n      inProgress: number;\n      completed: number;\n    };\n  };\n  workflow: {\n    runId: string;\n    agentsStarted: number;\n    result: JsonValue;\n  };\n  write: {\n    path: string;\n    operation: \"create\" | \"update\";\n    before: string | null;\n    after: string;\n  };\n}\n\ntype ToolName = keyof ToolOutputMap\n\ndeclare class ToolCallError extends Error {\n  readonly name: \"ToolCallError\";\n  readonly toolName: ToolName;\n}\n\ndeclare const tools: {\n  [K in ToolName]: (args: ToolArgsMap[K]) => Promise;\n}\n```","tools":[{"name":"bash","description":"Execute a bash command (`bash -c`) and return its stdout/stderr.

Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Mounts can COMPOSE: one plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically on unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned on unmount) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"Body of an async JS function; must `return` the plugin to mount."}},"required":["code"]}},{"name":"cordis_unmount","description":"Dispose a plugin previously mounted with cordis_mount, by id.

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

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

Subject: [PATCH 35/64] fix(tasks): producer diagnostics name the seam, not one
 implementation

Review feedback (tianyicui, PR #657 inline): the missing-service message
should mention dsh-tasks, which defines ctx.tasks, rather than promoting a
specific backend. The seam's own surfaces (README, the direct-mount fence)
keep pointing at implementations, so the pointer chain still lands on
dsh-tasks-local without the producer strings going stale when another
backend becomes the recommended default. Agent Note updated accordingly
(en+zh, re-recorded).

 The seam keeps the in-process contract semantics unchanged: `TaskStart.run()` still passes callbacks and exact `Agent` objects, so a durable or cross-process backend still has design work to do before it can implement this interface (identity, restart, ownership, observation).

 Bought: the task registry now matches the repository-wide seam shape; a durable, remote, or instrumented registry is a sibling package implementing eight abstract methods, and no producer, control surface, or `TaskKindMap` extender changes when one lands. The seam README states the contract; the implementation README owns the lifecycle bookkeeping facts. The registry behavior suite (owner cleanup, settlement, waits, teardown) lives with `dsh-tasks-local`; the seam keeps a stub-subclass test pinning registration under `ctx.tasks` and single-service duplication behavior, plus the probe-based invariant suite.
 
-Cost: one more package (manifest, tsconfig, README, invariant companion), and compositions must name the implementation package. `abstract` erases at runtime and this package name used to be the mountable registry, so the seam constructor fails loudly when mounted directly — a stale composition row gets "load an implementation such as @deepseek-ai/dsh-tasks-local" at load time instead of a half-registered `ctx.tasks` failing far from the misconfiguration. The misconfiguration diagnostics naming `dsh-tasks-local` accept staleness if a different backend becomes the recommended default.

Subject: [PATCH 36/64] fix: actually compact the cordis-dynamic fixture's
 request/header line

The previous hygiene fix re-serialized with json.dumps defaults (spaced
separators), leaving the line byte-identical; explicit compact
separators make the header-scrub guard pass.

Subject: [PATCH 37/64] test(web): pin every scenario end-state with an aria
 golden
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every spec now commits at least one golden and the interactive ones one
per distinct end-state (nine new .expected.md):

- live-interactions: cancel.expected.md (frozen partial + 已停止 marker),
  error-auth.expected.md (the prompt bubble alone — the committed artifact
  of the web-error-surface gap, the diff that flips when error rendering
  lands), retry.expected.md (indistinguishable from a clean completion —
  retries are deliberately invisible in the transcript).
- question-composer: answered.expected.md (the question resolved into its
  tool round trip plus the final reply, takeover gone) beside the existing
  waiting-state golden.
- steering: mid-steer.expected.md pins the accepted-but-INVISIBLE state
  (the loop drains steering only at the step boundary, so no interjection
  bubble exists while the question still blocks — if the client ever
  renders pending steers eagerly, this golden flips first) and
  settled.expected.md the badged bubble plus obeying reply.
- navigation-panes: waterfall.expected.md and details-open.expected.md
  (tool-name header, Input args, Output result) beside the trajectory one.
- lifecycle-chrome: reloaded.expected.md — rendering the same settled
  transcript from persistence alone IS the recovery claim.

Fixture inventories extended to the new closed sets; the Agent Note's
expected-outputs policy updated in both languages (per-end-state goldens
for interactive scenarios), pairing re-recorded.

+At least one committed golden per scenario, and one per DISTINCT end-state for the interactive scenarios (cancel/error/retry, waiting/answered, mid-steer/settled, panel-open, post-reload): a normalized `ariaSnapshot()` of the scenario's owning region — uuid/cwd/workspace-basename/duration tokens normalized, captured poll-until-equal at the settled milestone — plus a few role/text anchor assertions that stay green under a semantics-preserving component rewrite while the golden churns reviewably.

 The typecheck plane split is structural: the three files that boot the host spine (`scaffold`, `replay-round-trip.e2e`, and `seeded-history.e2e`) are excluded from the client-registered `apps/web` project. Those files and their shared `support.ts` are included file-by-file in `tsconfig.host.json` — one program cannot hold both sides of the cordis `Context` merges.
 
 ### Modes and fixtures
 
-`DSH_SNAPSHOT` selects replay (default, keyless), record (with key), or refresh (keyless) as inline spec branches — the TUI shape, not a suite factory: at two scenarios the acp-snapshot factory machinery has no owner, and the genuinely shared parts are already exported (`scrubRequestHeaders`, `parseSessionLog`, `installLlmReplay`). Each spec splits into drive steps (type, send, `whenTurnSettled` — run in all modes, never waiting on model-content selectors, so record cannot hang on a live model answering differently) and assertion steps (replay/refresh only). Record = drive live through the real composer + harvest the in-memory `session.header`/`session.events` (the TUI `rawSessionLog` shape — no file decompression) + `scrubRequestHeaders` + `{{sessionId}}`/`{{cwd}}`/`{{rpcId}}` tokenization; a follow-up keyless refresh regenerates `ui.expected.md`. Every prompting scenario's fixture was recorded against this assembly through this flow. A drift guard ties each spec's drive prompt to the fixture's recorded `user/message`. A fixture-inventory guard holds each scenario directory closed (exact file set, every JSONL a scrub fixed-point with no run-local `rpcId`). Web fixtures scrub headers everywhere and pin no header class, following the TUI precedent over the strict [pinned-header](2026-07-06-pin-request-header-content-in-one-scenario.md) reading — see Deferred.

 ### Scenarios
 
 1. **`replay-round-trip`** — new session, prompt through the real composer, replay streams reasoning + a `bash` tool call that really executes in the temp workspace + final text (paced 15ms). Asserts settled markdown, the aria golden, and inline world state (the bash call's durable result is exactly `WEB_E2E_OK\n`, completed `turn/end`, >10 chunk events).
 2. **`seeded-history`** — a recorded session seeded cold; the sidebar lists it (group row → session row, collapsed by default), opening renders tool cards and text purely from the log through the implicit cold-resume attach inside `session.history` — zero model calls in replay, so no binding constraints; record mode drives the same turn live (real `read` tool against seeded workspace files) to produce the seed.
-3. **`live-interactions`** — one tool-free recorded turn serves three replay-only scenarios through override sidecars whose CONTENT is authored in the spec and minted as a per-run file in a spec-owned temp dir (the derived success entry for the retry append is re-derived from the fixture via `deriveReplayScript`, never copied into a committed sidecar). Cancel: a `{ patches }` `hang` with a `readyFile` marker — the marker's existence proves the stream is parked mid-turn before the test clicks Stop, making mid-stream cancellation deterministic by construction (`turn/end` reason `aborted`, composer re-enabled). AUTH error: a pre-chunk `throw` outside llm-retry's retryable set (`turn/end` reason `error`, zero `llm/retry` events, composer recovers). SERVER retry: `throw` at call 0 + the fixture's own success appended at 1, proving llm-retry end-to-end in the browser via the durable `llm/retry` record (`request/header` logs only on change, so attempt count is invisible there).
-4. **`question-composer`** — the shipped composition's resident `ask_user_question` takeover: a recorded turn blocks mid-step on the real userInteraction seam, the composer (`[data-question-key]`) renders in the browser, the test answers through it (the ONE sanctioned place a drive step reacts to model content: the turn cannot complete without the answer, in record and replay alike), and the tool result carries the chosen label. Golden: the composer's stable waiting state.
-5. **`steering`** — mid-turn steer while the question composer blocks the step (the deterministic mid-turn window; no timing dependence). The composer locks while running, so the steer POSTs `session.prompt` `mode:'steer'` from the page over the same same-origin `/api` wire the client uses (`TODO(web-steer-composer)`: drive a composer gesture once one exists); everything downstream is product — gateway → `Agent.steer` → step-boundary drain → durable `steering/message` → SSE → badged interjection bubble. Record-mode fixture honesty: the recording is rejected unless the live model's final reply obeys an instruction only the steering message carries.
-6. **`navigation-panes`** — one rich two-turn seed (turn 1: bash + two parallel reads in one assistant message; turn 2: a markdown-heavy reply) rendered cold through the seeded-history pattern (zero model calls), serving four surfaces: sidebar search (client-side title filter — asserted only after the durable title lands with the attach baseline, because a cold `SessionSummary` carries no title and search matches the `displayTitle` the user sees; negative query empties the tree, positive narrows, clear restores), the Trajectory tab (turn sections + the step group's tool mix plus the view-area aria golden), the Waterfall tab (span stats + one lane per span — the P-I fold counts a turn-0 prologue span because only assistant/steering nodes carry a turn number, pinned as-is), and the details column (the bash toolview row routes click to openDetails; open/closed is asserted on the frame's `data-details-collapsed` attribute because close collapses the grid column to width 0 without unmounting the subtree).
-7. **`lifecycle-chrome`** — one tiny recorded text turn drives three whole-page concerns. Workspace flow over the real wire: the empty-state hero's first send materializes a real Workspace + Session (the jsdom `workspace-flow.snapshot.ts` suite pins this state machine over the fixture client; this scenario pins it through HTTP RPC + SSE + the gateway), proven durably by the session header's cwd being the create-by-name target `/workspace`, plus the hero waiting-state aria golden. Reload recovery: collapse the sidebar (persisted `dsh.layout.panels`), `page.reload`, and the surface comes back whole from persistence alone — layout collapsed, selection restored (`dsh.sessions.current`), the recorded turn re-rendered from `session.history` with zero model calls (the drained replay cursor makes any stray request fail loud at close). Dark mode: no product control flips the theme yet, so the scenario drives the ThemeService's entire DOM contract — the `body[data-ds-dark-theme]` attribute — and pins the shipped cascade: the alias token flips, a painted surface repaints, and removing the attribute restores the light sample exactly (`TODO(web-theme-gesture)` upgrades to a real settings control); per the scope ruling there is no theme/layout golden (aria is color-blind).
+3. **`live-interactions`** — one tool-free recorded turn serves three replay-only scenarios through override sidecars whose CONTENT is authored in the spec and minted as a per-run file in a spec-owned temp dir (the derived success entry for the retry append is re-derived from the fixture via `deriveReplayScript`, never copied into a committed sidecar).

SERVER retry: `throw` at call 0 + the fixture's own success appended at 1, proving llm-retry end-to-end in the browser via the durable `llm/retry` record (`request/header` logs only on change, so attempt count is invisible there). Each scenario pins its terminal surface as a golden: `cancel.expected.md` (frozen `partial`, 已停止 marker), `error-auth.expected.md` (the prompt bubble alone — the committed artifact of the web-error-surface gap, the diff that flips when error rendering lands), `retry.expected.md` (indistinguishable from a clean completion — retries are deliberately invisible in the transcript).
+4. **`question-composer`** — the shipped composition's resident `ask_user_question` takeover: a recorded turn blocks mid-step on the real userInteraction seam, the composer (`[data-question-key]`) renders in the browser, the test answers through it (the ONE sanctioned place a drive step reacts to model content: the turn cannot complete without the answer, in record and replay alike), and the tool result carries the chosen label.

Record-mode fixture honesty: the recording is rejected unless the live model's final reply obeys an instruction only the steering message carries. Goldens pin the timing semantics visually: `mid-steer.expected.md` captures the accepted-but-invisible state (the loop drains steering only at the step boundary, so no interjection bubble exists while the question still blocks — if the client ever renders pending steers eagerly, this golden flips first) and `settled.expected.md` the badged bubble plus obeying reply.

 ### 预期输出
 
-每场景一份提交的预期输出：会话区规范化 `ariaSnapshot()`（`ui.expected.md`）——uuid/cwd/工作区目录名/时长归一为稳定 token，在安定里程碑处轮询至两次相等再采集——外加几条 role/文本锚断言，让保语义的组件重写在预期输出可评审地变动时仍保持绿色锚点。aria 树是 client 规则「断言用户所见，绝不断言类名」的机械化。世界状态断言内联在根上下文的会话事件上（哪次工具调用产生了哪项已持久化的工具结果、`turn/end` 是否完成）而不是第二份提交的日志预期输出：持久化日志表面已由 ACP/headless/TUI 套件经同一循环和持久化钉住，在此重复钉住会违背分层纪律、翻倍刷新成本。`refresh` 是预期输出的唯一写入者——回放模式下预期输出缺失会连同修复命令一起报错，而不是静默自举。
+每场景至少一份提交的预期输出，交互类场景则每个不同终态各一份（取消/错误/重试、等待/已作答、steer 中途/安定、面板打开、重新加载后）：该场景所属区域的规范化 `ariaSnapshot()`——uuid/cwd/工作区目录名/时长归一为稳定 token，在安定里程碑处轮询至两次相等再采集——外加几条 role/文本锚断言，让保语义的组件重写在预期输出可评审地变动时仍保持绿色锚点。aria 树是 client 规则「断言用户所见，绝不断言类名」的机械化。世界状态断言内联在根上下文的会话事件上（哪次工具调用产生了哪项已持久化的工具结果、`turn/end` 是否完成）而不是第二份提交的日志预期输出：持久化日志表面已由 ACP/headless/TUI 套件经同一循环和持久化钉住，在此重复钉住会违背分层纪律、翻倍刷新成本。`refresh` 是预期输出的唯一写入者——回放模式下预期输出缺失会连同修复命令一起报错，而不是静默自举。
 
 类型检查平面切分是结构性的：启动 host 主干的三个文件（`scaffold`、`replay-round-trip.e2e` 和 `seeded-history.e2e`）被排除出注册在 client 侧的 `apps/web` 工程。这三个文件及其共享的 `support.ts` 逐文件纳入 `tsconfig.host.json`——一个程序不能同时持有 cordis `Context` 合并的两侧。
 
 ### 模式与 fixture
 
-`DSH_SNAPSHOT` 以内联 spec 分支选择 replay（默认，无密钥）、record（带密钥）或 refresh（无密钥）——TUI 的形态，不是套件工厂：两个场景撑不起 acp-snapshot 工厂机制，且真正共享的部分已被导出（`scrubRequestHeaders`、`parseSessionLog`、`installLlmReplay`）。每个 spec 切分为驱动步骤（输入、发送、`whenTurnSettled`——所有模式都执行，绝不等待模型内容选择器，因此 record 不会因真实模型答法不同而挂起）与断言步骤（仅 replay/refresh）。Record = 经真实输入框实时驱动 + 采收内存中的 `session.header`/`session.events`（TUI 的 `rawSessionLog` 形态——无需文件解压）+ `scrubRequestHeaders` + `{{sessionId}}`/`{{cwd}}`/`{{rpcId}}` token 化；随后一次无密钥 refresh 重新生成 `ui.expected.md`。每个发起提示的场景，其 fixture 都经此流程对本组装录制。一条漂移防线把每个 spec 的驱动提示词与 fixture 录制的 `user/message` 绑定。fixture 清单防线保持每个场景目录封闭（精确文件集合，每个 JSONL 都是脱敏不动点，不含当次运行的 `rpcId`）。Web fixture 全部脱敏请求头且不钉任何头类别，沿用 TUI 先例而非[钉住请求头](2026-07-06-pin-request-header-content-in-one-scenario.md)的严格读法——见「暂缓」。

 ### 场景
 
 1. **`replay-round-trip`**——新会话，经真实输入框发送提示词，回放流式输出推理（reasoning）+ 一次在临时工作区真实执行的 `bash` 工具调用 + 最终文本（15ms 节奏）。断言安定后的 markdown、aria 预期输出与内联世界状态（这次 bash 调用的已持久化工具结果严格等于 `WEB_E2E_OK\n`、完成的 `turn/end`、>10 个分片事件）。
 2. **`seeded-history`**——冷播种一份已录会话；侧栏列出它（分组行 → 会话行，默认折叠），打开后纯凭日志经 `session.history` 内的隐式冷恢复挂载渲染工具卡片与文本——replay 下零模型调用，因此没有任何绑定约束；record 模式实时驱动同一轮（真实 `read` 工具读取播种的工作区文件）来产出种子。
-3. **`live-interactions`**——一段不含工具调用的已录轮次经覆写 sidecar 承载三个仅回放的场景：sidecar 的内容本身写在 spec 里，每次运行时在 spec 自有的临时目录中生成文件（重试追加所用的派生成功条目经 `deriveReplayScript` 从 fixture 重新派生，绝不复制进已提交的 sidecar）。取消：一个带 `readyFile` 标记的 `{ patches }` `hang`——标记文件的存在证明流在测试点击 Stop 之前已停驻在轮次中途，使流中取消按构造即确定（`turn/end` 原因为 `aborted`，输入框重新启用）。AUTH 错误：一次落在 llm-retry 可重试集合之外的分片前 `throw`（`turn/end` 原因为 `error`，零条 `llm/retry` 事件，输入框恢复可用）。SERVER 重试：第 0 次调用 `throw` + 在第 1 次调用处追加 fixture 自身的成功条目，凭持久的 `llm/retry` 记录在浏览器中端到端证明 llm-retry（`request/header` 仅在变化时记录，因此尝试次数在那里不可见）。
-4. **`question-composer`**——已交付组合中常驻的 `ask_user_question` 接管：一段已录轮次在真实的 userInteraction seam 上阻塞于步骤中途，提问输入框（`[data-question-key]`）在浏览器中渲染，测试经它作答（这是驱动步骤对模型内容作出反应的唯一获准之处：没有这个回答，轮次无法完成，record 与 replay 皆然），工具结果携带所选的 label。预期输出：提问输入框稳定的等待态。
-5. **`steering`**——在提问输入框阻塞该步骤时做轮次中途 steering（中途引导），此即确定性的轮次中途窗口，不依赖任何时序。输入框在运行期间锁定，因此这一 steer 由页面经客户端所用的同一条同源 `/api` wire POST `session.prompt` `mode:'steer'`（`TODO(web-steer-composer)`：待有输入框手势后改为驱动它）；下游的一切都是产品路径——gateway → `Agent.steer` → 步骤边界排空 → 持久的 `steering/message` → SSE → 带徽标的插话气泡。record 模式的 fixture 诚实性：除非真实模型的最终回复遵循了一条只有 steering 消息才携带的指令，否则该次录制被拒绝。
-6. **`navigation-panes`**——一份内容丰富的双轮次种子（轮次 1：同一条 assistant 消息内的 bash + 两次并行 read；轮次 2：一段 markdown 密集的回复）经 seeded-history 模式冷渲染（零模型调用），承载四个表面：侧栏搜索（客户端标题过滤；仅在持久的标题随 attach 基线一同到达后才断言，因为冷的 `SessionSummary` 不携带标题，而搜索匹配的是用户所见的 `displayTitle`；反例查询清空整棵树，正例查询收窄，清除后复原）、Trajectory 标签页（轮次分节 + 步骤组的工具构成，外加视图区 aria 预期输出）、Waterfall 标签页（span 统计 + 每个 span 一条泳道；只有 assistant/steering 节点携带轮次编号，因此 P-I 折叠会将一个轮次 0 的序幕 span 计入，按原样钉住）与详情列（bash 工具视图行把点击路由到 openDetails；打开/关闭状态断言在 frame 的 `data-details-collapsed` 属性上，因为关闭把网格列收缩到宽度 0 而不卸载子树）。
-7. **`lifecycle-chrome`**——一段极小的已录纯文本轮次驱动三个整页关注点。真实 wire 上的 Workspace 动线：空态 hero 的首次发送物化出真实的 Workspace + Session（jsdom 的 `workspace-flow.snapshot.ts` 套件基于 fixture 客户端钉住这一状态机；本场景则经 HTTP RPC + SSE + gateway 钉住它），其持久证据是会话头部的 cwd 恰为按名创建的目标 `/workspace`，外加 hero 等待态的 aria 预期输出。重新加载恢复：折叠侧栏（持久化于 `dsh.layout.panels`），`page.reload`，整个表面纯凭持久化完整归来——布局保持折叠，选中项恢复（`dsh.sessions.current`），已录轮次从 `session.history` 重新渲染且零模型调用（已耗尽的回放游标使任何离群请求都在 close 时大声失败）。暗色模式：产品尚无任何控件能切换主题，因此本场景驱动 ThemeService 的整个 DOM 契约（即 `body[data-ds-dark-theme]` 属性），并钉住已交付的级联：alias token 翻转，某个实际绘制的表面重绘，移除该属性则精确还原亮色采样值（`TODO(web-theme-gesture)`：待有真实设置控件后升级为驱动它）；按范围裁定，主题/布局不设预期输出（aria 感知不到颜色）。
+3. **`live-interactions`**——一段不含工具调用的已录轮次经覆写 sidecar 承载三个仅回放的场景：sidecar 的内容本身写在 spec 里，每次运行时在 spec 自有的临时目录中生成文件（重试追加所用的派生成功条目经 `deriveReplayScript` 从 fixture 重新派生，绝不复制进已提交的 sidecar）。取消：一个带 `readyFile` 标记的 `{ patches }` `hang`——标记文件的存在证明流在测试点击 Stop 之前已停驻在轮次中途，使流中取消按构造即确定（`turn/end` 原因为 `aborted`，输入框重新启用）。AUTH 错误：一次落在 llm-retry 可重试集合之外的分片前 `throw`（`turn/end` 原因为 `error`，零条 `llm/retry` 事件，输入框恢复可用）。SERVER 重试：第 0 次调用 `throw` + 在第 1 次调用处追加 fixture 自身的成功条目，凭持久的 `llm/retry` 记录在浏览器中端到端证明 llm-retry（`request/header` 仅在变化时记录，因此尝试次数在那里不可见）。每个场景都把各自的终态表面钉为一份预期输出：`cancel.expected.md`（冻结的 `partial`、「已停止」标记）、`error-auth.expected.md`（仅有提示词气泡——web-error-surface 缺口的已提交产物，错误渲染落地时翻转的那份 diff）、`retry.expected.md`（与一次干净完成无从区分——重试在文本记录中刻意不可见）。
+4. **`question-composer`**——已交付组合中常驻的 `ask_user_question` 接管：一段已录轮次在真实的 userInteraction seam 上阻塞于步骤中途，提问输入框（`[data-question-key]`）在浏览器中渲染，测试经它作答（这是驱动步骤对模型内容作出反应的唯一获准之处：没有这个回答，轮次无法完成，record 与 replay 皆然），工具结果携带所选的 label。预期输出：提问输入框稳定的等待态（`ui.expected.md`）与已作答的文本记录（`answered.expected.md`——提问已落定为其工具往返加最终回复，接管消失）。
+5. **`steering`**——在提问输入框阻塞该步骤时做轮次中途 steering（中途引导），此即确定性的轮次中途窗口，不依赖任何时序。输入框在运行期间锁定，因此这一 steer 由页面经客户端所用的同一条同源 `/api` wire POST `session.prompt` `mode:'steer'`（`TODO(web-steer-composer)`：待有输入框手势后改为驱动它）；下游的一切都是产品路径——gateway → `Agent.steer` → 步骤边界排空 → 持久的 `steering/message` → SSE → 带徽标的插话气泡。record 模式的 fixture 诚实性：除非真实模型的最终回复遵循了一条只有 steering 消息才携带的指令，否则该次录制被拒绝。预期输出以可视方式钉住这一时序语义：`mid-steer.expected.md` 捕捉「已接受但不可见」的状态（循环仅在步骤边界才排空 steering，因此提问仍在阻塞时不存在插话气泡——若 client 日后提前渲染待处理的 steer，这份预期输出会最先翻转），`settled.expected.md` 则捕捉带徽标的气泡加遵循指令的回复。
+6. **`navigation-panes`**——一份内容丰富的双轮次种子（轮次 1：同一条 assistant 消息内的 bash + 两次并行 read；轮次 2：一段 markdown 密集的回复）经 seeded-history 模式冷渲染（零模型调用），承载四个表面：侧栏搜索（客户端标题过滤；仅在持久的标题随 attach 基线一同到达后才断言，因为冷的 `SessionSummary` 不携带标题，而搜索匹配的是用户所见的 `displayTitle`；反例查询清空整棵树，正例查询收窄，清除后复原）、Trajectory 标签页（轮次分节 + 步骤组的工具构成，外加视图区 aria 预期输出）、Waterfall 标签页（span 统计 + 每个 span 一条泳道；只有 assistant/steering 节点携带轮次编号，因此 P-I 折叠会将一个轮次 0 的序幕 span 计入，按原样钉住）与详情列（bash 工具视图行把点击路由到 openDetails；打开/关闭状态断言在 frame 的 `data-details-collapsed` 属性上，因为关闭把网格列收缩到宽度 0 而不卸载子树）。预期输出：`trajectory.expected.md` 与 `waterfall.expected.md`（各自标签页的视图区），外加 `details-open.expected.md`（打开的面板：工具名标题、Input 参数、Output 结果）。
+7. **`lifecycle-chrome`**——一段极小的已录纯文本轮次驱动三个整页关注点。真实 wire 上的 Workspace 动线：空态 hero 的首次发送物化出真实的 Workspace + Session（jsdom 的 `workspace-flow.snapshot.ts` 套件基于 fixture 客户端钉住这一状态机；本场景则经 HTTP RPC + SSE + gateway 钉住它），其持久证据是会话头部的 cwd 恰为按名创建的目标 `/workspace`，外加 hero 等待态的 aria 预期输出。重新加载恢复：折叠侧栏（持久化于 `dsh.layout.panels`），`page.reload`，整个表面纯凭持久化完整归来——布局保持折叠，选中项恢复（`dsh.sessions.current`），已录轮次从 `session.history` 重新渲染且零模型调用（已耗尽的回放游标使任何离群请求都在 close 时大声失败），且 `reloaded.expected.md` 钉住重建后的会话区——纯凭持久化渲染出同一份安定的文本记录，这本身就是恢复主张。暗色模式：产品尚无任何控件能切换主题，因此本场景驱动 ThemeService 的整个 DOM 契约（即 `body[data-ds-dark-theme]` 属性），并钉住已交付的级联：alias token 翻转，某个实际绘制的表面重绘，移除该属性则精确还原亮色采样值（`TODO(web-theme-gesture)`：待有真实设置控件后升级为驱动它）；按范围裁定，主题/布局不设预期输出（aria 感知不到颜色）。

Subject: [PATCH 38/64] fix(tools): close scheduler coverage gaps; regen
 persistence catalog
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The coverage gate flagged three untaken paths in the bridge scheduler:
- the exclusive-head inFlight re-check was dead (the shared guard above
  already returns for an exclusive head with any in-flight sibling) — removed;
- the commit-cursor undefined-dispatched break was structurally unreachable
  once entries join commitQueue only after start() ran synchronously —
  reordered the pump so the invariant holds by construction, annotated;
- the finish (final-result) commit arm and the pump re-entry guard gain a
  covering test (throwing tools/pre-execute listener) and a defensive
  annotation respectively; mid-run unregistration test renamed to match its
  actual post-result settlement path.

Also covers the direct-construction maxParallelSubCalls default (index.ts)
and commits the regenerated persistence catalog for the new dispatch pair.

Subject: [PATCH 39/64] docs: regenerate catalogs and register CodeDispatchLog
 type-equiv on this tree

The static CI gates run per-branch on the merged tree: the cordis
catalog/api, config-catalog, and type-equiv manifest updates for the
tools/code-dispatch-log waterfall and CodeDispatchLog payload previously
landed only on the shiki branch (09734f23b); this branch's own tree needs
the same regenerated outputs and manifest entries.

Subject: [PATCH 40/64] fix(client-runtime): settle-only dispatch windows carry
 null callTime
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Responding to ds-review-bot on #664 (root cause lives here): when a history
window carries a tool/code-dispatch settle without its paired start, the
runtime fabricated callTime = settle time, so downstream duration views
presented a measured 0 ms. Match the native tool-result contract instead —
callTime: null = unknown — and pin it; the trajectory cell already renders
null as the em dash, and the waterfall gains explicit unknown handling in
its own PR.

Subject: [PATCH 41/64] fix review findings: hostile code accessor + swallowed
 teardown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both ds-review-bot findings were real:

- markLlmAdapterFailure's carried-facts cross-check read error.code
  directly; a foreign Error with a valid own failure payload but a
  throwing code accessor would replace the original adapter error with
  the accessor exception, breaking the error-identity guarantee. The
  read now goes through foreignErrorCode(), which contains the trap and
  falls back to the normalized snapshot (test: hostile code accessor
  beside a valid failure payload -> original identity kept, UNKNOWN
  facts).
- live-interactions' afterEach caught scaffold.close() into undefined,
  silently disabling ReplayHandle.assertConsumed() — the fixture-drift
  tripwire — and hiding cleanup defects. Teardown now runs every step,
  collects failures, and rethrows (AggregateError when several).

Subject: [PATCH 42/64] fix(ui-trajectory): timing provenance on sub-span
 lanes; assembled snapshot for both views
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Responding to ds-review-bot on #664:

- SubSpanLane gains a 'timing' discriminant (measured | running | unknown).
  A settle-only replay entry (callTime null, start outside the window) was
  previously indistinguishable from a measured 0 ms span; it now renders
  hollow with a 'duration unknown' hover title, and durationMs stays null
  for anything unmeasured. Pairs with the client-runtime fix that stopped
  fabricating callTime = settle time (826c3696a on the live-parallel PR).

- The built-client Code Mode fixture snapshot now switches to the
  Trajectory and Waterfall tabs and pins the assembled rendering: three
  Sub cells with real +0.8s durations and three measured lanes with their
  hover titles — product-visible coverage through the real bundle graph,
  not just package-level jsdom fixtures.

Agent Note (both languages) updated for the timing contract; pairing
re-recorded.

 **Trajectory: `subtool` cells interleaved after their parent Tool cell. Waterfall: real-time sub-lanes under the owning turn row.**
 
 - **Trajectory**: the layout fold takes the snapshot's `codeDispatches` index; after each Tool cell whose `callId` has dispatches (assistant-block calls, orphan results, and running calls alike), it interleaves one `subtool` cell per sub-dispatch in start order — indexes stay sequential across the interleave. A settled sub-call's duration is its start/settle pair (`durationSeconds(sub.time, sub.callTime)`); a running one shows the em dash, exactly the native in-flight convention. The new cell kind wears a `Sub` tag (business tint) and a 28px indent so nesting reads at a glance.
-- **Waterfall**: `deriveSubSpans` folds the dispatch index into per-turn lanes with REAL timing — each parent's dispatch window is first start → last settle, and every lane's offset/width is its fraction of that window, so parallel sub-calls (PR3) visibly overlap. Running lanes extend to the window end at reduced opacity with a null duration. Lanes draw under the owning turn's bar row, scaled into a fixed lane budget.

Trajectory cell indexes now count sub-calls, so `#N` totals grow on Code Mode turns.

Subject: [PATCH 43/64] test: cover the dispatch-log seam's contained-failure
 and decline arms
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI's full-tree coverage flagged three untaken paths this PR introduced:
- shapeDispatchLog's catch (a throwing tools/code-dispatch-log listener
  must be contained — the settle event logs the unshaped content);
- the spill listener's flatten-decline arm (non-text sub-result content
  passes through unchanged);
- the generated scope-key extractor row for tools/code-dispatch-log
  (registered in the scope invariant matrix like the other tools events).

Subject: [PATCH 45/64] test(ui-primitives): cover the fence pre-routing arms;
 drop the unreachable array probe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI coverage flagged MarkdownText's pre route: the array-element probe
(raw[0]) and the mixed-content fallbacks were unreachable — the markdown
pipeline hands pre one code element whose children are one string (or
none, for an empty fence). Simplify to the string check, annotate the
isValidElement guard as representation-change armor, and pin both live
arms: the empty fence keeps the stock 
, a language-less fence renders
the plain CodeBlock arm.

 carries null callTime; README matches
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Responding to ds-review-bot round 2 on #653: the tool/code-dispatch event
is appended at settlement, so using its time as callTime fabricated a
zero-duration call for duration-aware consumers — it is now null (start
unknown) per the ToolResultNode contract, pinned in the session spec. The
README's codeDispatches section described the PR3 running→settled
lifecycle a stack ahead of this tree; it now documents the settled-only
index this PR ships (the running shape lands with the start event in
#658, which already merges cleanly over this).

Subject: [PATCH 48/64] fix(tools): single ordered driver lane for the
 sub-dispatch scheduler; validate the cap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Responding to ds-review-bot round 2 on #658 (three critical findings, one
warning — all rooted in the pump/commit split racing ordered stages):

- ONE driver lane now owns every ordered stage: the start append, prepare
  (pre-execute/guards), and the head-of-line commit (post-execute, context
  deferral, settle append). start() is awaited before the next entry can
  start, so concurrent submissions can no longer run pre-execute pipelines
  concurrently; only the around-dispatch/body stage overlaps, matching the
  native loop's fillPool sequencing.
- An exclusive call's barrier now holds through its COMMIT: later starts
  wait for the exclusive pipeline (post-execute included) to finish, the
  native exclusive-group semantics.
- drainDispatches() awaits the driver run itself, so a commit already
  mid-flight when the program returns is drained before run_code closes
  the turn — the settle event and deferred contexts land inside it.
- maxParallelSubCalls is resolved and validated at construction (positive
  integer), so direct construction can no longer wedge the pool with 0.

New tests: overlapping-submission ordered-prepare, barrier-through-commit,
drain-mid-commit, cap rejection. 96 keyless snapshots replay unchanged;
Agent Note updated (both languages).

The existing `tool/code-dispatch` settles the pair (same `subCallId`); every started call settles exactly once (aborts settle as `isError` outcomes through the pipeline). Timing = the two events' `time` fields. Both stay log-only; model context is untouched; format stays v0.

Consecutive parallel-classified calls overlap up to `maxParallelSubCalls` (a validated registry `Config` field, default 10 — the loop scheduler's own default; `1` restores serial dispatch); an exclusive call drains the pool, runs alone, and bars later calls. This is the loop's group semantics adapted to calls that arrive over time instead of in one parsed batch. Run settlement aborts in-flight dispatches and abandons queued-unstarted ones (binding rejection, no events), then drains to quiescence before the outer result closes the turn.
+- **Bridge scheduler**: submitted calls are classified at start time via `registry.executionMode` (the SAME fail-closed `isConcurrencySafe` contract the loop uses) and start strictly in submission order. One single-lane driver owns every ORDERED stage — the start append, `prepare` (pre-execute/guards), the head-of-line `finalize`/`finish` commit (post-execute + context deferral + settle append) — so ordered policy stages never overlap each other and only the around-dispatch/body stage runs concurrently, exactly the native loop's sequencing (`fillPool` awaits `startCall` then `commitReady`). Consecutive parallel-classified calls overlap up to `maxParallelSubCalls` (a `Config` field validated by the Loader schema AND re-validated at direct construction, default 10 — the loop scheduler's own default; `1` restores serial dispatch); an exclusive call drains the pool, runs alone, and holds its barrier until its COMMIT completes (post-execute included), like a native exclusive group. Run settlement aborts in-flight dispatches and abandons queued-unstarted ones (binding rejection, no events), then drains to quiescence — including a commit already mid-flight when the program returned — before the outer result closes the turn.
 - **Client**: `CodeSubCall` widens to `RunningToolCall | ToolResultNode` — a start event lands the running shape in the dispatch index (rows derive the running ring from the shape, exactly as for native in-flight calls), and its settle replaces the entry in place, preserving start order under parallel completion and carrying the start's `time` as `callTime` (duration source). A settle with no observed start (window cut mid-pair, or a pre-start-event log) appends directly, so old logs keep rendering.
 - **SDK prompt**: the model-facing "calls execute sequentially" sentence is replaced with the true contract (independent safe calls may overlap under `Promise.all`; dependent work sequences with `await`) — a model-visible change, re-recorded across every code-mode snapshot.

 - **事件对**：`tool/code-dispatch-start`（父/子 id、名称、规范化参数）在调度器真正启动某个调用时才追加，而非在提交时，因此因 run 结算而被放弃的排队调用不会留下任何日志。既有的 `tool/code-dispatch` 结算该事件对（`subCallId` 相同）；每个已启动的调用恰好结算一次（中止也会作为 `isError` 结果经由流水线结算）。计时即这两个事件的 `time` 字段。两个事件都保持仅日志；模型上下文不受影响；格式保持 v0。
-- **桥接层调度器**：已提交的调用在提交那一刻就经 `registry.executionMode` 分类（与 loop 所用完全相同的 fail-closed `isConcurrencySafe` 契约），并严格按提交顺序启动。连续被分类为可并行的调用可以重叠执行，上限为 `maxParallelSubCalls`（经校验的注册表 `Config` 字段，默认值 10，即 loop 调度器自身的默认值；设为 `1` 即恢复串行分发）；独占调用则先排空池、独自运行，并阻挡其后的调用。这是把 loop 的分组语义适配到另一种场景：调用随时间陆续到达，而非作为单个已解析的批次一次性到达。run 结算时会中止仍在运行的分发，并放弃已排队未启动的分发（绑定调用被拒绝，不产生事件），随后排空到完全停稳，之后外层结果才结束该轮次。
+- **桥接层调度器**：已提交的调用在启动那一刻经 `registry.executionMode` 分类（与 loop 所用完全相同的 fail-closed `isConcurrencySafe` 契约），并严格按提交顺序启动。所有有序阶段——start 事件追加、`prepare`（pre-execute/守卫）、队首 `finalize`/`finish` 提交（post-execute + 上下文延迟提交 + settle 事件追加）——由单一驱动车道独占执行，因此有序策略阶段彼此绝不重叠，只有 around-dispatch/工具体阶段并发运行，与原生 loop 的时序完全一致（`fillPool` 先 await `startCall` 再 `commitReady`）。连续被分类为可并行的调用可以重叠执行，上限为 `maxParallelSubCalls`（`Config` 字段，Loader schema 校验之外直接构造时也重新校验，默认值 10，即 loop 调度器自身的默认值；设为 `1` 即恢复串行分发）；独占调用则先排空池、独自运行，且其屏障保持到自身提交（含 post-execute）完成为止，与原生独占分组一致。run 结算时会中止仍在运行的分发，并放弃已排队未启动的分发（绑定调用被拒绝，不产生事件），随后排空到完全停稳——包括程序返回时已在途的提交——之后外层结果才结束该轮次。
 - **client 侧**：`CodeSubCall` 拓宽为 `RunningToolCall | ToolResultNode`：start 事件把运行中形状写入分发索引（行组件从该形状推导出运行指示环，与原生运行中的调用处理完全一致），其结算事件则原位替换该条目，即使并行完成也保持启动顺序不变，并把 start 事件的 `time` 作为 `callTime`（时长来源）带入。未观察到对应 start 的结算事件（窗口切在事件对中间，或日志录制于 start 事件引入之前）会直接追加，因此旧日志仍能照常渲染。
 - **SDK 提示词**：面向模型的「调用按顺序执行」一句替换为真实契约（相互独立的安全调用可以在 `Promise.all` 下重叠执行；相互依赖的工作以 `await` 顺序衔接）；这是模型可见的变更，每一份 code-mode 快照都已重新录制。

Subject: [PATCH 49/64] fix(tools): bound the shaped-append side channel; total
 error containment; recorded spill snapshot
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Responding to ds-review-bot round 2 on #661:

- logWork is bounded: past maxParallelSubCalls pending shaped-append tasks
  the ordered commit lane holds (Promise.race drains one), so a slow spill
  backend backpressures the run instead of accumulating unbounded pending
  I/O and retained results. Tasks self-remove on settlement; run
  settlement still drains every task inside the open turn. New spill test
  drives three oversized reads against a hung backend at cap 1 and proves
  the third dispatch cannot start until a save drains.
- shapeDispatchLog's catch uses errorMessage() (total), so a thrown value
  with a throwing toString cannot escape the containment and lose the
  settle event.
- CodeDispatchLog.content documented as the RENDERED result projection
  (native tool/result vocabulary), not what the program received — the
  program gets the structured value; doc pair + type-equiv re-synced.
- New RECORDED tui-agent snapshot scenario code-mode-dispatch-spill: the
  real Loader-visible composition (worker runtime + spill-local + policy)
  drives an oversized bash sub-call end-to-end; replay proves the durable
  dispatch copy is bounded to preview + locator while the program value
  stays whole (the outer result carries just the line count).

Agent Note updated (both languages).

Shaping runs OFF the program path as tracked side work, but bounded: past `maxParallelSubCalls` pending log tasks the ordered commit lane holds, so a slow spill backend backpressures the run instead of accumulating unbounded pending I/O; run settlement still drains every task inside the open turn.
 - **Policy**: `dsh-spill-policy` registers a second arm on the new seam sharing the exact replacement pipeline of its model-facing arm (same `maxInlineBytes` cap, same preview + locator + within-cap invariant, same best-effort fallbacks), with the artifact labeled `dispatch` under the sub-call id. UIs and replay read the full text through the spill artifact exactly as they do for spilled native results, so the native-parity rendering story survives bounding.
 - **One deliberate asymmetry**: the model-facing arm skips `read` (the `read → spill → read again` loop); the dispatch-log arm bounds `read` sub-calls too — a log copy is not model context, so the loop cannot happen, and `read` is precisely the tool that produces huge logs.

 - **策略**：`dsh-spill-policy` 在新 seam 上注册第二个分支，与其面向模型的分支共用一模一样的替换流水线（同样的 `maxInlineBytes` 上限、同样的预览 + 定位符 + 不超上限不变式、同样的尽力而为回退），产物以 `dispatch` 为标签，记在子调用 id 名下。UI 与回放通过 spill 产物读取全文，方式与读取被 spill 的原生结果完全相同，因此与原生同等保真的渲染在施加边界之后依然成立。
 - **一处有意的不对称**：面向模型的分支跳过 `read`（避免 `read → spill → read again` 循环）；分发日志分支则连 `read` 子调用也施加边界：日志副本不是模型上下文，该循环因此不可能发生，而 `read` 恰恰是会产生巨大日志的那个工具。

Subject: [PATCH 50/64] fix(ui-primitives): prototype-safe alias lookup;
 pre-warm shiki off the render path

Responding to ds-review-bot round 2 on #662:

- LANG_ALIASES is a Map: an assistant-authored fence label like
  constructor or __proto__ now misses (plain render) instead of resolving
  an inherited object property and crashing shiki mid-conversation. Test
  sweeps the inherited-key labels.
- The singleton is pre-warmed in a deferred task at plugin boot (the
  ~120-175ms engine+grammar construction long task moves off the first
  finalized fence's render); the lazy path remains the correctness
  fallback, and unref keeps non-browser imports from pinning the loop.

Agent Note updated (both languages).

 **Shiki in its synchronous fine-grained form, as one `ui-primitives` singleton, themed exclusively through CSS custom properties.**
 
 - **Dependency**: `shiki/core` + `@shikijs/langs`, composed via `createHighlighterCoreSync` with `createJavaScriptRegexEngine({ forgiving: true })` — no oniguruma WASM, no async init, bundle-friendly. Grammar allowlist: `typescript` (embeds JS), `shellscript`, `json` — the languages the harness actually renders; everything else falls back to a geometry-identical plain block, never an error. Prior art: the VitePress site already renders all documentation code through shiki, and TextMate grammars materially beat regex highlighters on TypeScript — the payload that matters here.
-- **Singleton**: `ui-primitives/src/markdown/highlight.ts` lazily creates one `HighlighterCore` per document and exposes `highlightToHtml(code, lang)` (undefined = render plain). The shared `CodeBlock` component owns both arms; its shiki arm injects the generated span tree via `dangerouslySetInnerHTML` — sanctioned because shiki emits a static span tree computed from the code text (no user HTML passes through, no scripts/handlers), shiki's own documented consumption path.
+- **Singleton**: `ui-primitives/src/markdown/highlight.ts` creates one `HighlighterCore` per document and exposes `highlightToHtml(code, lang)` (undefined = render plain). Engine + grammar construction is a ~120-175ms long task, so the module pre-warms the singleton in a deferred task at plugin boot (the lazy path stays as the correctness fallback), keeping the cost off the render path where a stream's finalize swap would jank. The alias table is a `Map`, not an object: fence info strings are assistant-authored, so a label like `constructor` must miss instead of resolving an inherited property and crashing shiki. The shared `CodeBlock` component owns both arms; its shiki arm injects the generated span tree via `dangerouslySetInnerHTML` — sanctioned because shiki emits a static span tree computed from the code text (no user HTML passes through, no scripts/handlers), shiki's own documented consumption path.
 - **Theming**: shiki's `createCssVariablesTheme` routes every token color through `--shiki-*` custom properties; the VALUES live in a new `ui-theme/styles/shiki.css` token sheet (light on `:root`, dark on `body[data-ds-dark-theme]` — the same cascade as every other sheet), imported by the shell's `base.css` chain. Component CSS stays tokens-only; no literal color ever enters JS or component sheets. Background/foreground alias the existing markdown code-block tokens so highlighted and plain blocks agree.
 - **Surfaces**: markdown fences (`MarkdownText`'s `pre` component routes single-string fences through `CodeBlock`), the `run_code` expanded program body (ToolRow's code variant, `lang="typescript"`), and the details panel's Input args (`lang="json"`). Output stays plain deliberately — tool output is arbitrary text, and guessing a grammar would mis-highlight more than it helps.

 **采用同步细粒度形态的 shiki，作为 `ui-primitives` 里的一个单例，主题化完全经由 CSS 自定义属性完成。**
 
 - **依赖**：`shiki/core` + `@shikijs/langs`，经 `createHighlighterCoreSync` 搭配 `createJavaScriptRegexEngine({ forgiving: true })` 组装——不带 oniguruma WASM、没有异步初始化、对 bundle 友好。语法（grammar）白名单：`typescript`（内嵌 JS）、`shellscript`、`json`——即 harness 实际会渲染的那几种语言；其余一律回退到几何完全一致的纯文本块，绝不报错。先例：VitePress 站点已经通过 shiki 渲染全部文档代码；而在 TypeScript（正是此处要紧的载荷）上，TextMate 语法实质性优于正则高亮器。
-- **单例**：`ui-primitives/src/markdown/highlight.ts` 为每个 document 惰性创建一个 `HighlighterCore`，并公开 `highlightToHtml(code, lang)`（undefined 即渲染为纯文本）。共享的 `CodeBlock` 组件同时拥有两条分支；其 shiki 分支经 `dangerouslySetInnerHTML` 注入生成的 span 树——此用法获准，因为 shiki 输出的是从代码文本计算出的静态 span 树（不流经任何用户 HTML，没有脚本或事件处理器），这正是 shiki 自身文档载明的消费路径。
+- **单例**：`ui-primitives/src/markdown/highlight.ts` 为每个 document 创建一个 `HighlighterCore`，并公开 `highlightToHtml(code, lang)`（undefined 即渲染为纯文本）。引擎加语法的构建是一次约 120-175ms 的长任务，因此模块在插件启动时用延迟任务预热单例（惰性路径保留为正确性兜底），把这笔开销挪出渲染路径——否则流式 finalize 交换的那一刻会卡顿。别名表用 `Map` 而非对象：fence 信息串由 assistant 撰写，诸如 `constructor` 这样的标签必须落空，而不是解析到继承属性并让 shiki 崩溃。共享的 `CodeBlock` 组件同时拥有两条分支；其 shiki 分支经 `dangerouslySetInnerHTML` 注入生成的 span 树——此用法获准，因为 shiki 输出的是从代码文本计算出的静态 span 树（不流经任何用户 HTML，没有脚本或事件处理器），这正是 shiki 自身文档载明的消费路径。
 - **主题化**：shiki 的 `createCssVariablesTheme` 让每一种 token 颜色都经由 `--shiki-*` 自定义属性路由；取值本身住在新增的 `ui-theme/styles/shiki.css` token 表里（亮色在 `:root`、暗色在 `body[data-ds-dark-theme]`——层叠方式与其余每张样式表相同），由壳的 `base.css` 导入链引入。组件 CSS 保持只用 token；任何字面颜色都不进入 JS 或组件样式表。背景/前景以别名指向既有的 markdown 代码块 token，使高亮块与纯文本块彼此一致。
 - **表面**：markdown 围栏代码块（`MarkdownText` 的 `pre` 组件把单字符串围栏路由到 `CodeBlock`）、`run_code` 展开后的程序正文（ToolRow 的 code 变体，`lang="typescript"`），以及 details 面板的 Input 参数（`lang="json"`）。输出有意保持纯文本——工具输出是任意文本，硬猜一种语法，带来的误高亮会多于帮助。

The scenario inspects the tools service API; the round-2 content-contract
JSDoc change shifted its rendered output. Keyless DSH_SNAPSHOT=refresh —
the resulting fixture is byte-identical to the one the shiki branch
already carries (the downstream trees were green for this reason).

 Web 和无头界面启动同一个共享组合（`cordis.yml`）：两者都将调用目录视为默认项目和 Workspace 根目录，除非通过 `--workspace-root ` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，并选用首条消息模型标题。无头界面唯一的差异是监听操作系统分配的端口（并行 `dsh -p` 运行绝不冲突；stderr 打印的 URL 会在浏览器中打开实时会话）。两者都需要先构建前端 dist 和客户端 bundle（`pnpm run build && pnpm run build:web`）。
 
+`DSH_TOOLS_MODE` 为整个 Web／无头进程选择工具呈现模式：可选值为 `native`（未设置时的 schema 默认值）、`code`（仅含 `run_code` 的 Code Mode 协议接口）或 `both`；任何其他值都会经由 `dsh-tools` 配置 schema 在启动时明确报错。它是一个临时 seam：Loader 组合是静态的，因此该设置作用于整个进程；待 Web UI 负责逐会话工具模式选择后便会移除。TUI 界面会忽略该变量（其配置树固定了自身模式）。

Subject: [PATCH 54/64] test(web): cover the settings surface and workspace
 management
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two new keyless scenarios for the functionality master gained since this
lane's base (#644 websettings, #643 workspace browser rework), both zero
model calls:

- settings-chrome: the modal shell (sidebar-foot trigger aria states,
  role=dialog, aria-current section switch to the deliberately empty
  Models, Escape + close-button paths, dialog aria golden); the Appearance
  row as the REAL theme gesture — retiring lifecycle-chrome's
  TODO(web-theme-gesture): clicking 深色 runs aria-pressed -> persisted
  dsh.theme -> body[data-ds-dark-theme] -> alias-token flip, survives
  reload, and 'system' follows the emulated OS scheme both ways; the
  Language row switches the settings-scoped copy to English (dsh.locale
  persisted, survives reload) and restores zh. Intentional reloads tear
  the SSE stream, so the spec drains exactly its own reconnect warnings —
  the tripwire still fails on unexpected connection loss.
- workspace-management: create-by-name twice through the region-header
  dialog (host-durable via ctx.workspace.list()); rename end to end —
  hover-revealed row menu (the button is display:none until the row
  hovers), duplicate-name pre-check (inline role=alert + disabled primary
  before any wire call), then workspace.rename through the real RPC,
  row update, host durability, reload survival; the flat 'In one list'
  view (section label flips, group headers drop, dsh.workspace.view
  persists across reload, grouped restored); the session hover card
  (dwell to open, closes on pointer leave). The one session row reuses
  seeded-history's committed seed — no new recording. Deliberately not
  driven: the inert menu rows and drag reorder (deferred in the note
  with re-entry triggers).

Agent Note gains scenarios 8-9 and the drag-reorder deferred item in both
languages; llm-replay README's zh side catches up with the { patches }

@@ -48,7 +48,9 @@ The typecheck plane split is structural: the three files that boot the host spin
 4. **`question-composer`** — the shipped composition's resident `ask_user_question` takeover: a recorded turn blocks mid-step on the real userInteraction seam, the composer (`[data-question-key]`) renders in the browser, the test answers through it (the ONE sanctioned place a drive step reacts to model content: the turn cannot complete without the answer, in record and replay alike), and the tool result carries the chosen label. Goldens: the composer's stable waiting state (`ui.expected.md`) and the answered transcript (`answered.expected.md` — the question resolved into its tool round trip plus the final reply, takeover gone).
 5. **`steering`** — mid-turn steer while the question composer blocks the step (the deterministic mid-turn window; no timing dependence). The composer locks while running, so the steer POSTs `session.prompt` `mode:'steer'` from the page over the same same-origin `/api` wire the client uses (`TODO(web-steer-composer)`: drive a composer gesture once one exists); everything downstream is product — gateway → `Agent.steer` → step-boundary drain → durable `steering/message` → SSE → badged interjection bubble. Record-mode fixture honesty: the recording is rejected unless the live model's final reply obeys an instruction only the steering message carries. Goldens pin the timing semantics visually: `mid-steer.expected.md` captures the accepted-but-invisible state (the loop drains steering only at the step boundary, so no interjection bubble exists while the question still blocks — if the client ever renders pending steers eagerly, this golden flips first) and `settled.expected.md` the badged bubble plus obeying reply.
 6. **`navigation-panes`** — one rich two-turn seed (turn 1: bash + two parallel reads in one assistant message; turn 2: a markdown-heavy reply) rendered cold through the seeded-history pattern (zero model calls), serving four surfaces: sidebar search (client-side title filter — asserted only after the durable title lands with the attach baseline, because a cold `SessionSummary` carries no title and search matches the `displayTitle` the user sees; negative query empties the tree, positive narrows, clear restores), the Trajectory tab (turn sections + the step group's tool mix plus the view-area aria golden), the Waterfall tab (span stats + one lane per span — the P-I fold counts a turn-0 prologue span because only assistant/steering nodes carry a turn number, pinned as-is), and the details column (the bash toolview row routes click to openDetails; open/closed is asserted on the frame's `data-details-collapsed` attribute because close collapses the grid column to width 0 without unmounting the subtree). Goldens: `trajectory.expected.md` and `waterfall.expected.md` (each tab's view area) plus `details-open.expected.md` (the open panel: tool-name header, Input args, Output result).
-7. **`lifecycle-chrome`** — one tiny recorded text turn drives three whole-page concerns. Workspace flow over the real wire: the empty-state hero's first send materializes a real Workspace + Session (the jsdom `workspace-flow.snapshot.ts` suite pins this state machine over the fixture client; this scenario pins it through HTTP RPC + SSE + the gateway), proven durably by the session header's cwd being the create-by-name target `/workspace`, plus the hero waiting-state aria golden. Reload recovery: collapse the sidebar (persisted `dsh.layout.panels`), `page.reload`, and the surface comes back whole from persistence alone — layout collapsed, selection restored (`dsh.sessions.current`), the recorded turn re-rendered from `session.history` with zero model calls (the drained replay cursor makes any stray request fail loud at close), and `reloaded.expected.md` pins the rebuilt conversation region — rendering the same settled transcript from persistence alone IS the recovery claim. Dark mode: no product control flips the theme yet, so the scenario drives the ThemeService's entire DOM contract — the `body[data-ds-dark-theme]` attribute — and pins the shipped cascade: the alias token flips, a painted surface repaints, and removing the attribute restores the light sample exactly (`TODO(web-theme-gesture)` upgrades to a real settings control); per the scope ruling there is no theme/layout golden (aria is color-blind).

Dark mode: the scenario drives the ThemeService's DOM contract seam directly — the `body[data-ds-dark-theme]` attribute — and pins the shipped cascade (alias token flips, a painted surface repaints, removal restores the light sample exactly), independent of the settings surface whose real user gesture `settings-chrome` owns; per the scope ruling there is no theme/layout golden (aria is color-blind).
+8. **`settings-chrome`** — the settings surface (#644), zero model calls on a blank frame. The modal shell: sidebar-foot trigger (`aria-haspopup`/`aria-expanded`) opens `role=dialog` 设置, General active by default with the skeleton rows plus the functional Language and Appearance rows (dialog aria golden), section switch moves `aria-current` to the deliberately empty Models, closes via Escape and the header close button. The Appearance row is the REAL theme gesture (retiring the lifecycle scenario's `TODO(web-theme-gesture)`): clicking 深色 runs the whole chain — `aria-pressed`, persisted `dsh.theme`, `body[data-ds-dark-theme]`, alias-token flip — and survives reload; `system` follows the emulated OS scheme both ways (`page.emulateMedia`), and the spec restores the light default for inter-spec hygiene. The Language row switches the settings-scoped copy to English (`dsh.locale` persisted, dialog re-registers as Settings/General/Appearance), survives reload, and restores zh — only the settings namespaces are localized today, so the scenario asserts exactly that surface. Intentional reloads tear the SSE stream, so the spec drains exactly the reconnect warnings its own reloads caused; the tripwire still fails on any unexpected connection loss.
+9. **`workspace-management`** — the workspace browser operations (#643), zero model calls (workspace.create/rename are host RPCs; the one session row comes from re-seeding seeded-history's committed seed, so no new fixture is recorded). Create-by-name twice through the region-header ＋ dialog (`workspace.create` mkdirs and prepends to the durable registry — asserted host-side via `ctx.workspace.list()`). Rename end to end: the hover-revealed row-actions menu (the button is `display:none` until its row hovers) → Rename dialog → the duplicate-name pre-check raises the inline `role=alert` and disables the primary button before any wire call → a fresh name goes through the `workspace.rename` RPC, updates the row, persists on the host, and survives reload. The flat "In one list" view: the Group by menu flips the section label to Sessions, drops group headers (seeded session becomes a top-level row), persists in `dsh.workspace.view` across reload, and the spec restores grouped mode. The session hover card renders after the dwell (display-only, no aria role — text anchors) and closes when the pointer leaves. Deliberately NOT driven: the visual-only menu rows this iteration ships inert (session Rename/Fork/Delete, workspace Delete) and drag reorder — see Deferred.

 - **Follow-up-prompt-after-resume scenario**: the history/live stitch path over the real wire; add as its own scenario when that code changes or regresses.
 - **Web error surface**: the client consumes no `agent/error` frames and a pre-chunk failure freezes no partial, so a non-retryable provider failure renders no error copy — the user sees the send simply stop. The AUTH scenario pins the current contract (no crash, composer recovers, turn logged `error`) and `FIXME(web-error-surface)` marks where visible error text gets asserted once the UI grows an error rendering.
 - **Composer steering gesture**: the input locks while running (stop-or-wait), so the steering scenario steers over the wire from the page; `TODO(web-steer-composer)` upgrades the drive step to a real composer gesture when the product grows one.
+- **Drag session reorder**: `workspace.insertSessionBefore` (manual ordering, #643) has no browser scenario yet — it needs two sessions materialized in ONE workspace (a two-script recorded fixture) plus synthesized HTML5 drag events; add it when that surface changes or regresses. The inert menu rows (session Rename/Fork/Delete, workspace Delete) get scenarios when they gain behavior.

 4. **`question-composer`**——已交付组合中常驻的 `ask_user_question` 接管：一段已录轮次在真实的 userInteraction seam 上阻塞于步骤中途，提问输入框（`[data-question-key]`）在浏览器中渲染，测试经它作答（这是驱动步骤对模型内容作出反应的唯一获准之处：没有这个回答，轮次无法完成，record 与 replay 皆然），工具结果携带所选的 label。预期输出：提问输入框稳定的等待态（`ui.expected.md`）与已作答的文本记录（`answered.expected.md`——提问已落定为其工具往返加最终回复，接管消失）。
 5. **`steering`**——在提问输入框阻塞该步骤时做轮次中途 steering（中途引导），此即确定性的轮次中途窗口，不依赖任何时序。输入框在运行期间锁定，因此这一 steer 由页面经客户端所用的同一条同源 `/api` wire POST `session.prompt` `mode:'steer'`（`TODO(web-steer-composer)`：待有输入框手势后改为驱动它）；下游的一切都是产品路径——gateway → `Agent.steer` → 步骤边界排空 → 持久的 `steering/message` → SSE → 带徽标的插话气泡。record 模式的 fixture 诚实性：除非真实模型的最终回复遵循了一条只有 steering 消息才携带的指令，否则该次录制被拒绝。预期输出以可视方式钉住这一时序语义：`mid-steer.expected.md` 捕捉「已接受但不可见」的状态（循环仅在步骤边界才排空 steering，因此提问仍在阻塞时不存在插话气泡——若 client 日后提前渲染待处理的 steer，这份预期输出会最先翻转），`settled.expected.md` 则捕捉带徽标的气泡加遵循指令的回复。
 6. **`navigation-panes`**——一份内容丰富的双轮次种子（轮次 1：同一条 assistant 消息内的 bash + 两次并行 read；轮次 2：一段 markdown 密集的回复）经 seeded-history 模式冷渲染（零模型调用），承载四个表面：侧栏搜索（客户端标题过滤；仅在持久的标题随 attach 基线一同到达后才断言，因为冷的 `SessionSummary` 不携带标题，而搜索匹配的是用户所见的 `displayTitle`；反例查询清空整棵树，正例查询收窄，清除后复原）、Trajectory 标签页（轮次分节 + 步骤组的工具构成，外加视图区 aria 预期输出）、Waterfall 标签页（span 统计 + 每个 span 一条泳道；只有 assistant/steering 节点携带轮次编号，因此 P-I 折叠会将一个轮次 0 的序幕 span 计入，按原样钉住）与详情列（bash 工具视图行把点击路由到 openDetails；打开/关闭状态断言在 frame 的 `data-details-collapsed` 属性上，因为关闭把网格列收缩到宽度 0 而不卸载子树）。预期输出：`trajectory.expected.md` 与 `waterfall.expected.md`（各自标签页的视图区），外加 `details-open.expected.md`（打开的面板：工具名标题、Input 参数、Output 结果）。
-7. **`lifecycle-chrome`**——一段极小的已录纯文本轮次驱动三个整页关注点。真实 wire 上的 Workspace 动线：空态 hero 的首次发送物化出真实的 Workspace + Session（jsdom 的 `workspace-flow.snapshot.ts` 套件基于 fixture 客户端钉住这一状态机；本场景则经 HTTP RPC + SSE + gateway 钉住它），其持久证据是会话头部的 cwd 恰为按名创建的目标 `/workspace`，外加 hero 等待态的 aria 预期输出。重新加载恢复：折叠侧栏（持久化于 `dsh.layout.panels`），`page.reload`，整个表面纯凭持久化完整归来——布局保持折叠，选中项恢复（`dsh.sessions.current`），已录轮次从 `session.history` 重新渲染且零模型调用（已耗尽的回放游标使任何离群请求都在 close 时大声失败），且 `reloaded.expected.md` 钉住重建后的会话区——纯凭持久化渲染出同一份安定的文本记录，这本身就是恢复主张。暗色模式：产品尚无任何控件能切换主题，因此本场景驱动 ThemeService 的整个 DOM 契约（即 `body[data-ds-dark-theme]` 属性），并钉住已交付的级联：alias token 翻转，某个实际绘制的表面重绘，移除该属性则精确还原亮色采样值（`TODO(web-theme-gesture)`：待有真实设置控件后升级为驱动它）；按范围裁定，主题/布局不设预期输出（aria 感知不到颜色）。

+8. **`settings-chrome`**——设置表面（#644），空白 frame 上零模型调用。模态框外壳：侧栏底部的触发按钮（`aria-haspopup`/`aria-expanded`）打开 `role=dialog` 的「设置」，默认激活「通用设置」，其中既有骨架行，也有具备实际功能的「语言」与「外观」两行（对话框 aria 预期输出）；分节切换把 `aria-current` 移到刻意留空的「模型」分节；经 Escape 与头部的「关闭」按钮均可关闭。「外观」行是真正的主题手势（lifecycle 场景的 `TODO(web-theme-gesture)` 就此撤除）：点击「深色」跑通整条链路（`aria-pressed`、持久化的 `dsh.theme`、`body[data-ds-dark-theme]`、alias token 翻转）并在重新加载后存续；`system` 双向跟随所模拟的操作系统配色方案（`page.emulateMedia`），该 spec 还会恢复「浅色」默认值以保证 spec 之间互不污染。「语言」行把设置范围内的文案切换为 English（`dsh.locale` 持久化，对话框重新注册为 Settings/General/Appearance），在重新加载后存续，最后恢复为「中文」——目前本地化只覆盖设置命名空间，因此该场景断言的恰是这一表面。有意的重新加载会撕断 SSE 流，因此该 spec 恰好只排空自身重新加载引发的重连警告；任何意外的连接丢失仍会触发绊线失败。
+9. **`workspace-management`**——工作区浏览器操作（#643），零模型调用（workspace.create/rename 是 host 侧 RPC；唯一的会话行来自重新播种 seeded-history 已提交的种子，因此没有录制任何新 fixture）。经区域头部的「＋」对话框按名创建两次（`workspace.create` 会 mkdir 并把新项前插到持久注册表——host 侧经 `ctx.workspace.list()` 断言）。端到端的重命名：悬停显露的行操作菜单（按钮在所在行悬停之前是 `display:none`）→ Rename 对话框 → 重名预检在发出任何 wire 调用之前就亮出内联 `role=alert` 并禁用主按钮 → 换一个全新名称则走 `workspace.rename` RPC，更新该行、在 host 上持久化并在重新加载后存续。扁平的「In one list」视图：Group by 菜单把分节标签翻转为 Sessions，去掉分组头（播种的会话成为顶层行），在 `dsh.workspace.view` 中持久化并跨重新加载存续，该 spec 最后恢复分组模式。会话悬停卡片在驻留延时后渲染（纯展示，无 aria role——用文本锚定），指针移开即关闭。刻意不驱动：本次迭代以无行为形态交付的纯视觉菜单行（会话的 Rename/Fork/Delete、工作区的 Delete）与拖拽重排——见「暂缓」。

 Fixture 就是持久化会话日志（`/session.jsonl`）。其 `assistant/chunk` 事件携带每个 `StreamChunk`，因此按 `(turn, step)` 对其分组可重建每次 `stream()` 调用的分片序列（每个 loop 步骤一次模型调用）。因此，录制操作是「运行一次真实 agent 并收集 `.jsonl`」，由快照 harness 完成；该插件不执行录制。Fixture 的 `request/header` 内容可能被 token 化为 `{{system}}`/`{{tools}}`（harness 在一个场景中固定该内容，并擦除其余场景）；回放对此并不关心，因为派生只读取 `assistant/chunk` 事件和第 0 行会话 header。
 
-有两种失败 mode 无法仅从 `assistant/chunk` 重建：在任何分片前纯抛出（例如 HTTP 401，日志只包含 `turn/end {error}` 而没有分片），以及 cancel/hang（是时序，而非分片内容）。需要这些的场景提供可选 sidecar（`/replay.override.json`：一个 `ReplayEntry[]`），以替换派生脚本。`hang` 条目可以指定 `readyFile`；在其前缀分片到达 loop 后、等待取消前，回放会写入该空标记，使外部驱动器可以在不观察展示更新的情况下确定性取消。

Subject: [PATCH 56/64] docs(tasks): bring the zh side of the tasks pairs along
 after the master merge

Master made bilingual pairing mandatory repo-wide; this PR's seam-split
edits to the tasks docs get their zh counterparts: a new pair for the
dsh-tasks-local README and minimal updates to the tasks core-data doc,
agent-spine-demo README, and the tasks family READMEs, with pairing
records re-recorded.

 Process-local implementation of the [`@deepseek-ai/dsh-tasks`](../tasks/README.md) registry seam: `LocalTaskService` keeps every record in memory, issues per-kind `-N` ids, and hands out fresh snapshots, never live state. It has no config; load it as a plugin and it registers as `ctx.tasks`.

+
+服务释放会关闭监听器、取消所有存活任务、等待其记录，并从仍存活的 owner scope 分离 effect。如果拆卸取消抛出异常，服务会强制把记录标为失败，并警告工作可能遗留，而不会死锁。取消已返回但始终不终止 `done` 时，系统无法将其与缓慢停止区分开，拆卸可能因此停滞。
+
+结算遵循首次结果优先：最早出现的终止结果（生产方结算、被隔离为 `failed` 的 `done` 拒绝，或拆卸强制失败）只记录一次，只通知监听器一次并对每个监听器单独隔离故障，然后释放等待方。挂起的等待会在监听器运行前把任务标记为已报告，因此呈现完成情况的表层不会重复发出通知。

 parallel-dispatch contract
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

master's bilingual README pairing (new since this branch forked) covers
packages/core/tools and packages/client/runtime, whose EN sides this PR
edits. Translate the scheduling-contract sentences (bridge pool, SDK
overlap line, loop cross-reference, codeDispatches lifecycle) into the zh
sides — including the verbatim shared model-facing block — and re-record
both pairing records.

 - **SDK 段**（`tools:sdk`，顺序 150）：一个惰性提示词段，每次组装时都会重新生成 `JsonValue`、精确的 `ToolArgsMap` / `ToolOutputMap`、`ToolName`、`ToolCallError` 声明、面向调用作用域可见最终能力的映射 `tools` 命名空间（特殊名称使用带引号的键），以及固定用法说明。其输出具有确定性：工具按字典序排列；工具集合不变时，文本逐字节相同（有利于前缀 cache）。导出的代码生成器 `jsonSchemaToTs` 会处理统一 schema 的每种构造，并将不受支持的原始构造降级为 `unknown`，绝不会在提示词组装期间抛出。
-- **分发桥接层**（`run_code` 的 execute）：每个绑定调用都会在分发前快照为无损 JSON（`undefined`、`BigInt`、循环、稀疏数组、`-0` 和特殊对象会使该次调用被拒绝），通过每次运行独有的队列串行化（即使使用 `Promise.all`，底层调用也会按提交顺序逐个执行），以外层执行的不透明 token 作为 `parent`，并经过完整的 pre-execute → guards → execute → post-execute → result 流水线。成功会返回策略处理后的最终规范值；失败以一条消息到达 worker，并成为 `ToolCallError(toolName, message)`。每个子调用都会记录为 `tool/code-dispatch` 会话事件，其确定性 id 为 `:code:`，并附带完整的模型可见 `content`/`isError` 结果（采用 `tool/result` 词汇，因此 UI 会沿原生路径呈现子调用）；`deriveMessages()` 不会公开该事件或持久化规范值。token 关联让以提交为语义的观察器能够把内部成功延迟到最终 `run_code` 结果，而无需公开实时外层执行；普通工具副作用不会回滚。每个子调用的 `additionalContexts` 条目都会按分发顺序通过外层 `ToolRunContext` 延迟；循环只在父级 `run_code` 结果之后追加这些上下文，从而保持相邻关系，并且即使程序后来失败，也会保留各自的来源／元数据。

 - **结算纪律**：桥接层拥有一次运行作用域的中止；该中止会跟随传入的外层信号，并在运行因任何原因结算时触发，因此预算耗尽会中止正在运行的子工具，而不会将其遗留。桥接层随后会在返回之前 drain 队列，使每个 `tool/code-dispatch` 都落在仍打开的轮次内。失败的运行会抛出 `CodeRunFailedError`（`code: 'CODE_RUN_FAILED'`，message = 失败类型 + 已捕获日志），流水线会将其转换为模型可据以自我修正的结构化 `isError`。
 - **结果边界**：中间绑定值会完整跨越 worker 边界，且没有逐绑定字节上限。`run_code` 返回规范的 `{ logs: string[], result?: JsonValue }`；字符串原样呈现，其他所有存在的 JSON 根都通过栈安全的美化 JSON 遍历呈现，总缩进最多为 10 个字符（更深的子树保持紧凑），`null` 保持显式，而缺少 `result` 表示程序返回 `undefined`。worker 可配置的 `maxOutputBytes`（默认 64 MiB）只应用于组合序列化后的外层日志数组、完成值或失败消息载荷；固定的结果 envelope 语法和呈现空白不计入该账本。无效和超限的完成会明确失败，只有此外层结果可以使用普通 spill。
 
 ### 并行执行

+# Agent Note: Retarget PR bases incrementally

+Status: implemented

+
+## Problem
+
+A PR base can advance while its current tip is being merged into the PR branch. Restarting from the newer tip discards completed conflict resolution and validation. Rewriting a merge that is already pushed also erases reviewable history.
+
+## Decision
+
+Each observed base tip gets its own merge checkpoint. If the base advances during the work, finish and validate the merge already in progress, commit it, and push it when the task authorizes a push. Only then fetch and merge the newer base in a separate merge commit. Never abandon, amend, rebase, or otherwise rewrite the earlier work.
+
+The root [AGENTS.md](../../../../AGENTS.md) states the standing order. The [stacked-PR landing skill](../../../skills/dsh-merging-stacked-prs/SKILL.md) applies it while retargeting dependent PRs, and the [stack review guide](../../../../docs/cookbook/responding-to-pr-review-on-a-stack.md) owns merging fixes down a stack.
+
+## Alternatives considered
+
+**Abort and restart from the newest base.** This discards resolved conflicts and completed validation, repeats work, and removes a useful recovery point.
+
+**Fold both base tips into one rewritten merge.** This hides the order in which conflicts were resolved and requires rewriting remote history if the first merge was pushed.
+
+## Consequences
+
+- A PR can carry several base-merge commits when its base advances repeatedly.
+- Completed work remains reviewable and recoverable instead of being discarded.
+- Merging a newer base changes the combined tree, so the relevant checks run again before the next push.

+# Agent Note: 增量更新 PR 的 base 分支
+
+Status: implemented
+
+[English](2026-07-26-incremental-pr-base-retargeting.md) | 中文
+
+## 问题
+
+将 PR（Pull Request）的 base 分支当前顶端提交合入 PR 分支的过程中，base 分支可能继续前移。若改从新的顶端提交重新开始，就会丢弃已经完成的冲突解决和验证工作。重写已经推送的合并还会抹去可供评审的历史记录。
+
+## 决策
+
+每次观察到的 base 分支顶端提交都保留为独立的合并检查点。如果处理期间 base 分支继续前移，先完成并验证正在进行的合并，再将其提交；任务授权推送时，还要完成推送。完成这些步骤后，才能拉取较新的 base，并通过单独的合并提交将其合入。绝不放弃先前工作，也不通过 amend、rebase 或其他方式重写它。
+
+根 [AGENTS.md](../../../../AGENTS.md) 规定了这项常设指令。[堆叠 PR 落地 skill（技能）](../../../skills/dsh-merging-stacked-prs/SKILL.md)在调整依赖 PR 的 base 时执行这一规则，[堆叠评审指南](../../../../docs/cookbook/responding-to-pr-review-on-a-stack.md)则负责说明如何将修复沿堆叠向下合并。
+
+## 曾考虑的替代方案
+
+**中止当前工作，改从最新 base 重新开始。** 这会丢弃已经解决的冲突和完成的验证，重复劳动，并失去一个有用的恢复点。
+
+**重写为一次同时包含两个 base 分支顶端的合并。** 这会掩盖冲突解决的顺序；如果第一次合并已经推送，还必须重写远程历史。
+
+## 后果
+
+- PR 的 base 多次前移时，这个 PR 可以包含多个用于合并 base 的提交。
+- 已完成的工作不会被丢弃，而是保持可供评审和恢复。
+- 合入较新的 base 会改变合并后的文件树，因此相关检查会在下一次推送前重新运行。

No new package; the product deltas are additive `dsh-llm-replay` surfaces (`paceMs`, `ReplayHandle`, and the `{ patches }` override form: indexed augmentation over the derived script so a sidecar expresses "call N throws / hangs, everything else replays as recorded" without copying recorded chunks), one `dsh-llm` fix the retry scenario exposed (a carried `failure` snapshot is honored on any Error — the `instanceof` gate dropped provider codes across dual package copies, source-plane replay over a lib-plane boot), and the `llm-retry` row the web composition was missing.

The supporting product contracts are `dsh-llm-replay` pacing, consumption checks, and validated indexed override patches; cross-package `dsh-llm` failures retain validated provider facts through own data properties; and the shipped web composition mounts `llm-retry` for transient model failures.

 ### Expected outputs
 
-At least one committed golden per scenario, and one per DISTINCT end-state for the interactive scenarios (cancel/error/retry, waiting/answered, mid-steer/settled, panel-open, post-reload): a normalized `ariaSnapshot()` of the scenario's owning region — uuid/cwd/workspace-basename/duration tokens normalized, captured poll-until-equal at the settled milestone — plus a few role/text anchor assertions that stay green under a semantics-preserving component rewrite while the golden churns reviewably. The aria tree is the mechanization of the client rule "assert what the user would see, never class names". World-state assertions ride root-context session events inline (which tool call produced which durable result, whether `turn/end` completed) instead of a second committed log golden: the persisted-log surface is pinned by the ACP/headless/TUI suites through the same loop and persistence, and re-pinning it here would double refresh cost against the tier discipline. `refresh` is the sole golden writer — a missing golden in replay mode fails with the healing command rather than self-bootstrapping.
+Scenarios with a stable owning region commit a normalized `ariaSnapshot()` for each distinct user-visible state; cross-region workspace-management states instead use semantic DOM assertions plus authoritative host-state checks. UUID, cwd, workspace basename, and duration volatility collapse to stable tokens; captures poll until consecutive normalized reads agree. Role and text anchors remain semantic guards around the reviewable goldens and own cross-region states directly. World-state assertions use root-context session events rather than a second committed log golden because the ACP, headless, and TUI suites already pin the persisted-log surface through the same loop and persistence. `refresh` is the sole golden writer; a missing replay golden fails with the regeneration command.
 
-The typecheck plane split is structural: the three files that boot the host spine (`scaffold`, `replay-round-trip.e2e`, and `seeded-history.e2e`) are excluded from the client-registered `apps/web` project. Those files and their shared `support.ts` are included file-by-file in `tsconfig.host.json` — one program cannot hold both sides of the cordis `Context` merges.

 ### Modes and fixtures
 
-`DSH_SNAPSHOT` selects replay (default, keyless), record (with key), or refresh (keyless) as inline spec branches — the TUI shape, not a suite factory: at two scenarios the acp-snapshot factory machinery has no owner, and the genuinely shared parts are already exported (`scrubRequestHeaders`, `parseSessionLog`, `installLlmReplay`). Each spec splits into drive steps (type, send, `whenTurnSettled` — run in all modes, never waiting on model-content selectors, so record cannot hang on a live model answering differently) and assertion steps (replay/refresh only). Record = drive live through the real composer + harvest the in-memory `session.header`/`session.events` (the TUI `rawSessionLog` shape — no file decompression) + `scrubRequestHeaders` + `{{sessionId}}`/`{{cwd}}`/`{{rpcId}}` tokenization; a follow-up keyless refresh regenerates the aria goldens. Every prompting scenario's fixture was recorded against this assembly through this flow. A drift guard ties each spec's drive prompt to the fixture's recorded `user/message`. A fixture-inventory guard holds each scenario directory closed (exact file set, every JSONL a scrub fixed-point with no run-local `rpcId`). Web fixtures scrub headers everywhere and pin no header class, following the TUI precedent over the strict [pinned-header](2026-07-06-pin-request-header-content-in-one-scenario.md) reading — see Deferred.
+`DSH_SNAPSHOT` selects replay (default, keyless), record (with key), or refresh (keyless). Prompting specs separate drive steps shared by all modes from replay/refresh assertions; record mode drives the live composer, harvests the in-memory session header and events, scrubs request headers, and tokenizes run-local session, cwd, and RPC identities. A follow-up keyless refresh regenerates aria goldens. Each prompt is checked against its fixture's recorded `user/message`, and each scenario directory has a closed inventory whose JSONL files are scrub fixed points. Web fixtures scrub headers everywhere and pin no header class; see Deferred.
 
-### Scenarios
+### Coverage contract
 
-1. **`replay-round-trip`** — new session, prompt through the real composer, replay streams reasoning + a `bash` tool call that really executes in the temp workspace + final text (paced 15ms). Asserts settled markdown, the aria golden, and inline world state (the bash call's durable result is exactly `WEB_E2E_OK\n`, completed `turn/end`, >10 chunk events).
-2. **`seeded-history`** — a recorded session seeded cold; the sidebar lists it (group row → session row, collapsed by default), opening renders tool cards and text purely from the log through the implicit cold-resume attach inside `session.history` — zero model calls in replay, so no binding constraints; record mode drives the same turn live (real `read` tool against seeded workspace files) to produce the seed.
-3. **`live-interactions`** — one tool-free recorded turn serves three replay-only scenarios through override sidecars whose CONTENT is authored in the spec and minted as a per-run file in a spec-owned temp dir (the derived success entry for the retry append is re-derived from the fixture via `deriveReplayScript`, never copied into a committed sidecar). Cancel: a `{ patches }` `hang` with a `readyFile` marker — the marker's existence proves the stream is parked mid-turn before the test clicks Stop, making mid-stream cancellation deterministic by construction (`turn/end` reason `aborted`, composer re-enabled). AUTH error: a pre-chunk `throw` outside llm-retry's retryable set (`turn/end` reason `error`, zero `llm/retry` events, composer recovers). SERVER retry: `throw` at call 0 + the fixture's own success appended at 1, proving llm-retry end-to-end in the browser via the durable `llm/retry` record (`request/header` logs only on change, so attempt count is invisible there). Each scenario pins its terminal surface as a golden: `cancel.expected.md` (frozen `partial`, 已停止 marker), `error-auth.expected.md` (the prompt bubble alone — the committed artifact of the web-error-surface gap, the diff that flips when error rendering lands), `retry.expected.md` (indistinguishable from a clean completion — retries are deliberately invisible in the transcript).
-4. **`question-composer`** — the shipped composition's resident `ask_user_question` takeover: a recorded turn blocks mid-step on the real userInteraction seam, the composer (`[data-question-key]`) renders in the browser, the test answers through it (the ONE sanctioned place a drive step reacts to model content: the turn cannot complete without the answer, in record and replay alike), and the tool result carries the chosen label. Goldens: the composer's stable waiting state (`ui.expected.md`) and the answered transcript (`answered.expected.md` — the question resolved into its tool round trip plus the final reply, takeover gone).
-5. **`steering`** — mid-turn steer while the question composer blocks the step (the deterministic mid-turn window; no timing dependence). The composer locks while running, so the steer POSTs `session.prompt` `mode:'steer'` from the page over the same same-origin `/api` wire the client uses (`TODO(web-steer-composer)`: drive a composer gesture once one exists); everything downstream is product — gateway → `Agent.steer` → step-boundary drain → durable `steering/message` → SSE → badged interjection bubble. Record-mode fixture honesty: the recording is rejected unless the live model's final reply obeys an instruction only the steering message carries. Goldens pin the timing semantics visually: `mid-steer.expected.md` captures the accepted-but-invisible state (the loop drains steering only at the step boundary, so no interjection bubble exists while the question still blocks — if the client ever renders pending steers eagerly, this golden flips first) and `settled.expected.md` the badged bubble plus obeying reply.
-6. **`navigation-panes`** — one rich two-turn seed (turn 1: bash + two parallel reads in one assistant message; turn 2: a markdown-heavy reply) rendered cold through the seeded-history pattern (zero model calls), serving four surfaces: sidebar search (client-side title filter — asserted only after the durable title lands with the attach baseline, because a cold `SessionSummary` carries no title and search matches the `displayTitle` the user sees; negative query empties the tree, positive narrows, clear restores), the Trajectory tab (turn sections + the step group's tool mix plus the view-area aria golden), the Waterfall tab (span stats + one lane per span — the P-I fold counts a turn-0 prologue span because only assistant/steering nodes carry a turn number, pinned as-is), and the details column (the bash toolview row routes click to openDetails; open/closed is asserted on the frame's `data-details-collapsed` attribute because close collapses the grid column to width 0 without unmounting the subtree). Goldens: `trajectory.expected.md` and `waterfall.expected.md` (each tab's view area) plus `details-open.expected.md` (the open panel: tool-name header, Input args, Output result).
-7. **`lifecycle-chrome`** — one tiny recorded text turn drives three whole-page concerns. Workspace flow over the real wire: the empty-state hero's first send materializes a real Workspace + Session (the jsdom `workspace-flow.snapshot.ts` suite pins this state machine over the fixture client; this scenario pins it through HTTP RPC + SSE + the gateway), proven durably by the session header's cwd being the create-by-name target `/workspace`, plus the hero waiting-state aria golden. Reload recovery: collapse the sidebar (persisted `dsh.layout.panels`), `page.reload`, and the surface comes back whole from persistence alone — layout collapsed, selection restored (`dsh.sessions.current`), the recorded turn re-rendered from `session.history` with zero model calls (the drained replay cursor makes any stray request fail loud at close), and `reloaded.expected.md` pins the rebuilt conversation region — rendering the same settled transcript from persistence alone IS the recovery claim. Dark mode: the scenario drives the ThemeService's DOM contract seam directly — the `body[data-ds-dark-theme]` attribute — and pins the shipped cascade (alias token flips, a painted surface repaints, removal restores the light sample exactly), independent of the settings surface whose real user gesture `settings-chrome` owns; per the scope ruling there is no theme/layout golden (aria is color-blind).
-8. **`settings-chrome`** — the settings surface (#644), zero model calls on a blank frame. The modal shell: sidebar-foot trigger (`aria-haspopup`/`aria-expanded`) opens `role=dialog` 设置, General active by default with the skeleton rows plus the functional Language and Appearance rows (dialog aria golden), section switch moves `aria-current` to the deliberately empty Models, closes via Escape and the header close button. The Appearance row is the REAL theme gesture (retiring the lifecycle scenario's `TODO(web-theme-gesture)`): clicking 深色 runs the whole chain — `aria-pressed`, persisted `dsh.theme`, `body[data-ds-dark-theme]`, alias-token flip — and survives reload; `system` follows the emulated OS scheme both ways (`page.emulateMedia`), and the spec restores the light default for inter-spec hygiene. The Language row switches the settings-scoped copy to English (`dsh.locale` persisted, dialog re-registers as Settings/General/Appearance), survives reload, and restores zh — only the settings namespaces are localized today, so the scenario asserts exactly that surface. Intentional reloads tear the SSE stream, so the spec drains exactly the reconnect warnings its own reloads caused; the tripwire still fails on any unexpected connection loss.
-9. **`workspace-management`** — the workspace browser operations (#643), zero model calls (workspace.create/rename are host RPCs; the one session row comes from re-seeding seeded-history's committed seed, so no new fixture is recorded). Create-by-name twice through the region-header ＋ dialog (`workspace.create` mkdirs and prepends to the durable registry — asserted host-side via `ctx.workspace.list()`). Rename end to end: the hover-revealed row-actions menu (the button is `display:none` until its row hovers) → Rename dialog → the duplicate-name pre-check raises the inline `role=alert` and disables the primary button before any wire call → a fresh name goes through the `workspace.rename` RPC, updates the row, persists on the host, and survives reload. The flat "In one list" view: the Group by menu flips the section label to Sessions, drops group headers (seeded session becomes a top-level row), persists in `dsh.workspace.view` across reload, and the spec restores grouped mode. The session hover card renders after the dwell (display-only, no aria role — text anchors) and closes when the pointer leaves. Deliberately NOT driven: the visual-only menu rows this iteration ships inert (session Rename/Fork/Delete, workspace Delete) and drag reorder — see Deferred.
+The lane covers three behavior families. Live-turn scenarios pin ordinary tool execution, cancellation, non-retryable failure, transient retry, resident questions, and mid-turn steering; synchronization uses durable events, `whenIdle()`, or an explicit replay marker rather than delays. Cold-history scenarios seed through the real persistence API and cover history rendering, sidebar search, trajectory and waterfall views, and tool details without model calls. Browser-lifecycle scenarios cover first-send workspace materialization, reload recovery, layout persistence, theme and locale preferences, and workspace create/rename/view operations. Each family asserts the browser surface and the authoritative host state; a stray model call or under-consumed fixture fails teardown.

-6. **`navigation-panes`**——一份内容丰富的双轮次种子（轮次 1：同一条 assistant 消息内的 bash + 两次并行 read；轮次 2：一段 markdown 密集的回复）经 seeded-history 模式冷渲染（零模型调用），承载四个表面：侧栏搜索（客户端标题过滤；仅在持久的标题随 attach 基线一同到达后才断言，因为冷的 `SessionSummary` 不携带标题，而搜索匹配的是用户所见的 `displayTitle`；反例查询清空整棵树，正例查询收窄，清除后复原）、Trajectory 标签页（轮次分节 + 步骤组的工具构成，外加视图区 aria 预期输出）、Waterfall 标签页（span 统计 + 每个 span 一条泳道；只有 assistant/steering 节点携带轮次编号，因此 P-I 折叠会将一个轮次 0 的序幕 span 计入，按原样钉住）与详情列（bash 工具视图行把点击路由到 openDetails；打开/关闭状态断言在 frame 的 `data-details-collapsed` 属性上，因为关闭把网格列收缩到宽度 0 而不卸载子树）。预期输出：`trajectory.expected.md` 与 `waterfall.expected.md`（各自标签页的视图区），外加 `details-open.expected.md`（打开的面板：工具名标题、Input 参数、Output 结果）。
-7. **`lifecycle-chrome`**——一段极小的已录纯文本轮次驱动三个整页关注点。真实 wire 上的 Workspace 动线：空态 hero 的首次发送物化出真实的 Workspace + Session（jsdom 的 `workspace-flow.snapshot.ts` 套件基于 fixture 客户端钉住这一状态机；本场景则经 HTTP RPC + SSE + gateway 钉住它），其持久证据是会话头部的 cwd 恰为按名创建的目标 `/workspace`，外加 hero 等待态的 aria 预期输出。重新加载恢复：折叠侧栏（持久化于 `dsh.layout.panels`），`page.reload`，整个表面纯凭持久化完整归来——布局保持折叠，选中项恢复（`dsh.sessions.current`），已录轮次从 `session.history` 重新渲染且零模型调用（已耗尽的回放游标使任何离群请求都在 close 时大声失败），且 `reloaded.expected.md` 钉住重建后的会话区——纯凭持久化渲染出同一份安定的文本记录，这本身就是恢复主张。暗色模式：本场景直接驱动 ThemeService 的 DOM 契约 seam（即 `body[data-ds-dark-theme]` 属性），并钉住已交付的级联（alias token 翻转，某个实际绘制的表面重绘，移除该属性则精确还原亮色采样值），且独立于设置表面——该表面的真实用户手势归 `settings-chrome` 管；按范围裁定，主题/布局不设预期输出（aria 感知不到颜色）。
-8. **`settings-chrome`**——设置表面（#644），空白 frame 上零模型调用。模态框外壳：侧栏底部的触发按钮（`aria-haspopup`/`aria-expanded`）打开 `role=dialog` 的「设置」，默认激活「通用设置」，其中既有骨架行，也有具备实际功能的「语言」与「外观」两行（对话框 aria 预期输出）；分节切换把 `aria-current` 移到刻意留空的「模型」分节；经 Escape 与头部的「关闭」按钮均可关闭。「外观」行是真正的主题手势（lifecycle 场景的 `TODO(web-theme-gesture)` 就此撤除）：点击「深色」跑通整条链路（`aria-pressed`、持久化的 `dsh.theme`、`body[data-ds-dark-theme]`、alias token 翻转）并在重新加载后存续；`system` 双向跟随所模拟的操作系统配色方案（`page.emulateMedia`），该 spec 还会恢复「浅色」默认值以保证 spec 之间互不污染。「语言」行把设置范围内的文案切换为 English（`dsh.locale` 持久化，对话框重新注册为 Settings/General/Appearance），在重新加载后存续，最后恢复为「中文」——目前本地化只覆盖设置命名空间，因此该场景断言的恰是这一表面。有意的重新加载会撕断 SSE 流，因此该 spec 恰好只排空自身重新加载引发的重连警告；任何意外的连接丢失仍会触发绊线失败。
-9. **`workspace-management`**——工作区浏览器操作（#643），零模型调用（workspace.create/rename 是 host 侧 RPC；唯一的会话行来自重新播种 seeded-history 已提交的种子，因此没有录制任何新 fixture）。经区域头部的「＋」对话框按名创建两次（`workspace.create` 会 mkdir 并把新项前插到持久注册表——host 侧经 `ctx.workspace.list()` 断言）。端到端的重命名：悬停显露的行操作菜单（按钮在所在行悬停之前是 `display:none`）→ Rename 对话框 → 重名预检在发出任何 wire 调用之前就亮出内联 `role=alert` 并禁用主按钮 → 换一个全新名称则走 `workspace.rename` RPC，更新该行、在 host 上持久化并在重新加载后存续。扁平的「In one list」视图：Group by 菜单把分节标签翻转为 Sessions，去掉分组头（播种的会话成为顶层行），在 `dsh.workspace.view` 中持久化并跨重新加载存续，该 spec 最后恢复分组模式。会话悬停卡片在驻留延时后渲染（纯展示，无 aria role——用文本锚定），指针移开即关闭。刻意不驱动：本次迭代以无行为形态交付的纯视觉菜单行（会话的 Rename/Fork/Delete、工作区的 Delete）与拖拽重排——见「暂缓」。
+该车道覆盖三类行为。实时轮次场景钉住普通工具执行、取消、不可重试失败、瞬态重试、常驻提问与轮次中途 steering；同步依赖持久事件、`whenIdle()` 或显式回放标记，而不使用延时。冷历史场景通过真实持久化 API 播种，在不调用模型的情况下覆盖历史渲染、侧栏搜索、Trajectory 与 Waterfall 视图及工具详情。浏览器生命周期场景覆盖首次发送时物化工作区、重新加载恢复、布局持久化、主题与语言偏好，以及工作区的创建、重命名和视图操作。每类场景都断言浏览器表面和权威的 host 状态；离群的模型调用或未耗尽的 fixture 会使拆卸失败。

 The fixture IS the persisted session log (`/session.jsonl`). Its `assistant/chunk` events carry every `StreamChunk`, so grouping them by `(turn, step)` reconstructs each `stream()` call's chunk sequence (one model call per loop step). Recording is therefore "run the real agent once and harvest the `.jsonl`", done by the snapshot harness — this plugin does not record. A fixture may carry its `request/header` content tokenized to `{{system}}`/`{{tools}}` (the harness pins that content in one scenario and scrubs the rest); replay is indifferent — derivation reads only `assistant/chunk` events and the line-0 session header.
 
-Two failure modes are not reconstructable from `assistant/chunk` alone — a pure throw before any chunk (e.g. an HTTP 401, where the log holds only a `turn/end {error}` and no chunks) and a cancel/hang (timing, not chunk content). A scenario that needs those supplies an optional sidecar (`/replay.override.json`) that either REPLACES the derived script (a bare `ReplayEntry[]`) or AUGMENTS it (`{ patches: [{ at, entry }] }`: keep every JSONL-derived call, swap only the named 0-based call indexes; `at` equal to the derived length appends — the slot for the retry attempt that follows an injected transient throw). A `hang` entry may name `readyFile`; replay writes that empty marker after its prefix chunks reach the loop and before it waits for cancellation, so an external driver can cancel deterministically without observing a presentation update.

Subject: [PATCH 61/64] refactor(tools): shapeDispatchLog off the public
 registry surface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Responding to review on #661: a public method on the generic ToolRegistry
service whose only caller is the run_code bridge was ad-hoc surface
widening. The bridge now receives it as a registry-private capability
closure in RunCodeBridgeOptions (the requireRuntime idiom, alongside the
cap), the method is private, and it leaves the generated service
catalog/API surfaces.

The pattern is now named as a code smell where reviewers look: the
packages/AGENTS.md capability-interface rule gains the inverse-smell
clause (ceiling 660→675 — the list is at capacity and the clause needs
one sentence), and dsh-code-review's capability-fit check tells reviewers
to flag single-consumer public service methods and require the closure
form.

Challenge unrelated features and speculative generality, then test the PR's coherence against [the root contract](../../../AGENTS.md#conventions).
 - **Configuration and public choices:** ask what current-consumer evidence or prior art supports each default, public operation set, format, or imported external concept. Require an explicit choice or deferral when that evidence is absent.

 - **Policy**: `dsh-spill-policy` registers a second arm on the new seam sharing the exact replacement pipeline of its model-facing arm (same `maxInlineBytes` cap, same preview + locator + within-cap invariant, same best-effort fallbacks), with the artifact labeled `dispatch` under the sub-call id. UIs and replay read the full text through the spill artifact exactly as they do for spilled native results, so the native-parity rendering story survives bounding.
 - **One deliberate asymmetry**: the model-facing arm skips `read` (the `read → spill → read again` loop); the dispatch-log arm bounds `read` sub-calls too — a log copy is not model context, so the loop cannot happen, and `read` is precisely the tool that produces huge logs.

 - **策略**：`dsh-spill-policy` 在新 seam 上注册第二个分支，与其面向模型的分支共用一模一样的替换流水线（同样的 `maxInlineBytes` 上限、同样的预览 + 定位符 + 不超上限不变式、同样的尽力而为回退），产物以 `dispatch` 为标签，记在子调用 id 名下。UI 与回放通过 spill 产物读取全文，方式与读取被 spill 的原生结果完全相同，因此与原生同等保真的渲染在施加边界之后依然成立。
 - **一处有意的不对称**：面向模型的分支跳过 `read`（避免 `read → spill → read again` 循环）；分发日志分支则连 `read` 子调用也施加边界：日志副本不是模型上下文，该循环因此不可能发生，而 `read` 恰恰是会产生巨大日志的那个工具。

Every PR that changes product-user-visible GUI behavior now includes a
demonstration GIF with real provenance (that branch's built tree, real
key, real model rounds). Recording stays side-effect-free; the skill
gains a bounded final publication step: GIFs go on an append-only
orphan assets branch (one per PR series) and embed via the blob URL
with ?raw=true, never on the PR branch itself.

Folds in the operational lessons from the Code Mode UI series:
.playwright-mcp/ screenshot roots (now gitignored), per-PR staging and
precise server teardown, one-call DOM polling for transient states,
exact-text completion predicates, prompt engineering for UI states,
and the export-before-invoke GIF_SKILL_DIR encoder pitfall.

Agent Note: implemented/process/2026-07-26-gui-pr-gif-evidence-and-assets-branch (+ zh pair); the 2026-07-23 recording note now defers publication policy to it.

It uses the available browser-control workflow, establishes whether the requested flow is real, fixture-backed, or otherwise simulated, and captures a small storyboard only after semantically observable UI states. Frames live under the repository's gitignored `.playwright-mcp/` directory — the browser tool writes only under its allowed roots — and never dirty the worktree.

 **Keep an inline `ffmpeg` recipe in the skill.** Reconstructing quoting, timing manifests, palette filters, overwrite behavior, and post-encode checks in every run is error-prone. A bundled helper keeps those mechanics executable while the skill owns capture judgment.

+**Include GitHub attachment and description editing.** Upload and remote mutation require separate authentication, confirmation, and recovery rules. Keeping recording itself local and reversible preserves that boundary; the [GUI-PR GIF evidence decision](2026-07-26-gui-pr-gif-evidence-and-assets-branch.md) owns the bounded publication step for tasks that do attach the GIF to a pull request.
 
 **Use a fixture whenever it is easier to stage.** Fixtures are valid when the requested demonstration is explicitly fixture-backed, but they do not substantiate a real-server or real-API claim. The skill preserves the requested provenance and reports a missing prerequisite instead of silently changing it.

+# Agent Note: GUI pull request GIF evidence and assets-branch publication
+
+Status: implemented
+
+English | [中文](2026-07-26-gui-pr-gif-evidence-and-assets-branch.zh.md)
+
+## Problem
+
+A pull request that changes what a product user sees in the GUI is otherwise reviewed through prose and test names, neither of which shows the rendered result. The [browser-demo GIF recording](2026-07-23-browser-demo-gif-recording.md) skill produces truthful local GIFs but deliberately stopped at the local artifact, so each pull request that wanted to show one re-derived publication on its own — and committing the GIF to the pull request branch is never acceptable, because binary media in history bloats every future clone permanently.
+
+The recording procedure itself also kept being re-learned failure by failure: screenshots written outside the browser tool's allowed roots or into missing directories fail at capture time, transient UI states polled across separate tool calls are lost because the turn settles between calls, substring completion predicates match the echo of the user's own prompt, and an inline environment-variable assignment on the encoder command expands too late to take effect.
+
+## Decision
+
+Every pull request that changes product-user-visible GUI behavior includes a demonstration GIF recorded with the [record-browser-gif skill](../../../skills/record-browser-gif/SKILL.md), with real provenance — a real server booted from that pull request's own branch tree, a real API key, and real model rounds — stated next to the embed. Fixture provenance is acceptable only when the user explicitly asked for it.
+
+The GIF is published to a dedicated orphan assets branch — no parent commit, media only — never to the pull request branch; one assets branch serves a whole pull request series (existing branches: `code-mode-ui-assets`, `pr-613-assets`). Publication works in a shallow single-branch scratch clone, commits as `assets:  gif (#)`, and the pull request body embeds the blob URL with the required `?raw=true` suffix. Assets branches are append-only: merged pull request bodies reference their URLs forever, so an assets branch is never rewritten or deleted.
+
+Recording itself stays side-effect-free; publication is a bounded final step the skill performs only when the task includes attaching the GIF to a pull request. This amends the recording/upload boundary recorded in the [browser-demo GIF recording note](2026-07-23-browser-demo-gif-recording.md), which stays current for the recording half.
+
+The skill folds in the operational lessons recording earned: frames go under `.playwright-mcp/`, ignored by the repository `.gitignore` and created before capture, because the browser tool writes only under its allowed roots and resolves relative names against the repository root; each pull request stages its own built tree with a fresh scratch workspace and a new session per scenario, and servers are stopped by PID rather than a broad process-name pattern; transient states are captured by driving a slow foreground operation and polling a concrete DOM marker inside one browser-script call; completion predicates match an exact-text element rather than a substring; and the encoder runs with `GIF_SKILL_DIR` exported on its own line, per-frame durations holding the settled state longest, and both a JSON-summary check and a visual read of the encoded GIF.
+
+## Alternatives considered
+
+**Commit the GIF to the pull request branch.** Binary media merged into the default branch stays in history for every future clone and fetch; a demo GIF's value ends at review while its cost never does.
+
+**Attach the GIF as a GitHub upload.** Drag-and-drop `user-attachments` uploads are not available to a command-line workflow, cannot be re-created or audited from the repository, and leave the media's lifecycle outside repository control.
+
+**Store GIFs with Git LFS.** LFS still couples media to the code branch's history, adds an infrastructure dependency to every clone and CI fetch, and buys nothing over an isolated branch that ordinary git already supports.
+
+**One assets branch per pull request.** A branch per pull request sprawls the ref namespace and multiplies scratch clones during a series; one branch per series keeps publication a single push while staying isolated from code history.
+
+**Keep publication out of the recording skill.** That was the prior state; it preserved a clean boundary but made every pull request re-derive the same procedure. The boundary survives as an explicit gate — publication runs only when the task includes attaching the GIF to a pull request — instead of as omission.
+
+**Leave the GIF optional per pull request.** Optional evidence disappears under schedule pressure exactly where it matters most; a GUI change reviewed without a recording asks reviewers to imagine the rendered result or rebuild the branch themselves.
+
+## Consequences
+
+Every GUI pull request carries visual evidence with stated provenance, and reviewers see the change without rebuilding the branch. Repository history stays free of media; the cost moves to append-only assets branches that grow forever, stay cheap to clone shallowly, and can never be deleted. Mandatory real-provenance recording adds a real-key, real-model round to every GUI pull request's workflow — deliberate, because that run is the evidence. The recording half remains locally reversible, and a GIF request whose task does not include attaching it to a pull request still ends at the verified local artifact.

+# Agent Note: GUI PR 的 GIF 证据与 assets 分支发布
+
+Status: implemented
+
+[English](2026-07-26-gui-pr-gif-evidence-and-assets-branch.md) | 中文
+
+## 问题
+
+改变产品用户在 GUI 中所见行为的 PR（Pull Request），此前只能通过文字描述和测试名称接受评审，两者都无法展示渲染结果。[浏览器演示 GIF 录制](2026-07-23-browser-demo-gif-recording.md)对应的 skill（技能）能生成真实可信的本地 GIF，但刻意止步于本地产物，于是每个想展示 GIF 的 PR 都得各自重新摸索发布方式；而把 GIF 提交到 PR 分支从来不可接受：进入历史的二进制媒体会永久增大之后每一次克隆的体积。
+
+录制流程本身也在靠一次次失败反复重新学习：截图写到浏览器工具允许的根目录之外或写入不存在的目录，会在截取时直接失败；跨多次工具调用轮询的瞬态 UI 状态会丢失，因为调用之间轮次已经结算；用子串匹配做完成判定会命中用户自己提示词的回显；在编码器命令上内联赋值环境变量则因参数先于赋值展开而不生效。
+
+## 决策
+
+每个改变产品用户可见 GUI 行为的 PR 都包含一个用 [record-browser-gif skill](../../../skills/record-browser-gif/SKILL.md) 录制的演示 GIF，其来源必须真实：从该 PR 自身分支树启动的真实服务器、真实 API 密钥、真实的模型轮次，并在嵌入处注明来源。只有当用户明确要求 fixture（测试前置数据）来源时才可使用 fixture。
+
+GIF 发布到专用的孤儿（orphan）assets 分支上：该分支没有父提交、只含媒体，GIF 绝不进入 PR 自己的分支；一个 assets 分支服务整个 PR 系列（现有分支：`code-mode-ui-assets`、`pr-613-assets`）。发布在浅层单分支的临时克隆中进行，提交信息形如 `assets:  gif (#)`，PR 正文用带必需 `?raw=true` 后缀的 blob URL 嵌入。assets 分支只允许追加：已合并的 PR 正文会永远引用其 URL，因此 assets 分支绝不重写或删除。
+
+录制本身保持无副作用；发布是一个有边界的收尾步骤，仅当任务包含把 GIF 附到 PR 时才由该 skill 执行。这修订了[浏览器演示 GIF 录制记录](2026-07-23-browser-demo-gif-recording.md)中记录的录制/上传边界；录制部分仍以该记录为准。
+
+该 skill 还吸收了录制实践换来的操作经验：帧文件放在仓库 `.gitignore` 忽略的 `.playwright-mcp/` 目录下并在截取前先创建，因为浏览器工具只能写入其允许的根目录，相对文件名也相对仓库根目录解析；每个 PR 从自己构建的分支树启动服务，配以全新的临时工作区目录，每个录制场景新开会话，停止服务器时按 PID 精确匹配而不是用宽泛的进程名模式；瞬态状态靠驱动一个缓慢的前台操作、并在同一次浏览器脚本调用内轮询具体的 DOM 标记来截取；完成判定匹配精确文本元素而非子串；编码器在单独一行 export `GIF_SKILL_DIR` 之后运行，逐帧时长让最终稳定状态停留最久，并同时核对 JSON 摘要与目视检查编码后的 GIF。
+
+## 曾考虑的替代方案
+
+**把 GIF 提交到 PR 分支。**合入默认分支的二进制媒体会留在历史中，影响之后的每一次克隆和拉取；演示 GIF 的价值止于评审，代价却永不消失。
+
+**作为 GitHub 附件上传。**拖拽产生的 `user-attachments` 上传对命令行工作流不可用，无法从仓库重建或审计，媒体的生命周期也脱离仓库的控制。
+
+**用 Git LFS 存储 GIF。**LFS 仍把媒体耦合进代码分支的历史，给每次克隆和 CI 拉取增加一项基础设施依赖，相比普通 git 即可支持的隔离分支没有任何额外收益。
+
+**每个 PR 一个 assets 分支。**按 PR 建分支会让 ref 命名空间蔓延，并在一个系列内成倍增加临时克隆；每个系列一个分支让发布只需一次推送，同时仍与代码历史隔离。
+
+**把发布留在录制 skill 之外。**这是此前的状态；它保住了干净的边界，却让每个 PR 重新摸索同一套流程。这个边界如今以显式条件的形式保留：仅当任务包含把 GIF 附到 PR 时才执行发布，而不是靠省略来体现。
+
+**让 GIF 在每个 PR 中保持可选。**可选的证据恰恰会在最需要它的进度压力下消失；没有录制的 GUI 变更评审，等于要求评审人自行想象渲染结果或重新构建分支。
+
+## 后果
+
+每个 GUI PR 都携带注明来源的可视证据，评审人无需重新构建分支即可看到变更。仓库历史保持不含媒体；代价转移到只追加的 assets 分支上：它们会持续增长、可以低成本地浅克隆、且永远不能删除。强制的真实来源录制给每个 GUI PR 的工作流增加一次真实密钥、真实模型轮次的运行，这是有意为之，因为这次运行本身就是证据。录制部分仍然在本地可撤销；任务不包含附到 PR 的 GIF 请求，仍以已验证的本地产物结束。

+Produce a short, truthful UI demonstration as a local GIF, and — only when the task includes attaching it to a pull request — publish it through the assets-branch workflow at the end of this skill. Use the browser-control skill for interaction and the bundled encoder for repeatable timing, dimensions, and size.
+
+## Every GUI pull request includes a GIF
+
+A pull request that changes product-user-visible GUI behavior MUST include a demonstration GIF recorded with this skill and embedded in the pull request body via [the assets-branch workflow](#publish-to-an-assets-branch).
+
+The GIF's provenance is part of the evidence and must be real: a real server booted from that pull request's own branch tree, a real API key, and real model rounds. Never substitute fixture queries, mock transports, synthetic event injection, or test-only hooks unless the user explicitly asked for fixture provenance. State the provenance next to the embed — which tree served, which mode flags, that a real model round ran — so reviewers know exactly what the recording proves.
 
 ## Keep the boundary explicit
 
-- Produce frame images and one local `.gif` artifact only.
-- Never upload the artifact, post a comment, or change a pull request, issue, or document under this skill. Hand those actions to a separate workflow if the user requests them.
+- Recording produces frame images and one local `.gif` artifact only; it never mutates remote state.
+- Publication — pushing the GIF to an assets branch and embedding it in a pull request body — is the separate final step, performed only when the task includes attaching the GIF to a pull request. It never touches the pull request's own branch.
 - Preserve the requested provenance. A real-server or real-API demo must not use fixture queries, mock transports, synthetic event injection, or test-only hooks. If credentials or the server are unavailable, report that limitation instead of substituting a fixture.
 - Never read or expose credential values. Use the application's normal configuration path and a benign demonstration prompt.
 
+## Stage the application
+
+A GIF for a specific pull request demonstrates that pull request's tree, so stage per pull request:
+
+1. Build the branch tree being demonstrated — here, `pnpm run build && pnpm run build:web` — from the worktree that holds that branch. A GIF recorded against another branch's build misattributes the evidence.
+2. Boot one server per port from that tree, giving each recording a fresh scratch workspace directory so leftover sessions cannot appear in frames. Source the root `.env` for the API key through the application's normal path; never echo the key.
+3. Start a new session for each recorded scenario so earlier turns do not pollute the frames.
+4. When switching between pull requests, stop the old server by PID or an exact match on its command line. A broad `pkill -f` pattern can match and kill the shell that launched it — including your own.
+
 ## Record the flow
 
 1. Invoke the available browser-control skill and follow its setup, interaction, and cleanup instructions. Use the user's existing Chrome state only when requested or required.
 2. Resolve the evidence boundary before recording: identify the exact origin, whether the app is built or in development, the transport, and any fixture or mock mode. Record only claims that the observed setup supports.
-3. Choose three to six states that tell one story, such as initial, typed, submitted, and completed. Prefer semantic state changes over continuous capture; omit loading churn that does not help the viewer.
-4. Keep one viewport and crop for every frame. Store frames in an absolute artifact directory outside the Git worktree unless the user requests another location, and name them lexically: `00-initial.png`, `01-typed.png`, and so on.
-5. Before each screenshot, wait for a concrete UI condition such as a unique label, enabled control, changed document title, or completed response. Do not use a fixed delay as proof that the application reached the state.
-6. Capture no secrets, personal data, unrelated tabs, or transient notifications. Stop any unnecessarily long real-API run after the demonstrated state is visible.
+3. Choose three to six states that tell one story, such as typed, running, settled, and detail. Prefer semantic state changes over continuous capture; omit loading churn that does not help the viewer.
+4. Keep one viewport and crop for every frame, and name frames lexically: `00-initial.png`, `01-typed.png`, and so on.
+5. Store frames under the repository's gitignored `.playwright-mcp/` directory — browser-tool screenshots can only be written under the tool's allowed roots, and relative filenames resolve against the repository root. Create the frame subdirectory first (`mkdir -p .playwright-mcp/gif-frames-
