 AgentLoop privately owns one `TurnCancellation` per prospective turn. It installs the holder before notifying `agent/status = running`, retains its single `AbortController` through inbox claim, `agent/pre-step`, prompt assembly, every step, model and tool execution, and `agent/turn-stopping`, then clears the exact holder immediately before publishing `turn/end`. Terminal event observers and the following durability flush therefore cannot cancel already-completed turn work even though driver status may remain `running` until the flush settles. Every participating method, event, and request value receives that same explicit signal; the next turn receives a fresh signal.
 
-The driver keeps only a cause-less pre-run marker for queued work cancelled before a turn is claimed. An effective `cancel()` emits the observe-only `agent/cancel-requested` notification with its resolved typed cause before clearing queued and steering work or aborting the holder; notification failures cannot veto the stop, and an idle call emits nothing. Work synchronously queued by a notification observer is included in that clear, while work queued by a later signal abort observer belongs to the next turn. If a `running` listener synchronously cancels old work and sends a replacement, the driver discards the aborted holder and creates a fresh one for the replacement. Repeated cancellation is first-wins for the active holder, while later calls may still clear newly queued pending work.

Work synchronously queued by a notification observer is included in that clear, while work queued by a later signal abort observer is latched and runs when the aborted activity converges to idle — a `disposed` cancel leaves it parked ([cancel-convergence wake latch](../bug-fix/2026-08-07-cancel-convergence-wake-latch.md)).

Repeated cancellation is first-wins for the active holder, while later calls may still clear newly queued pending work.
 
 The explicit event signatures pass a single payload object: agent-scoped events carry `agent` and `signal` in the payload with `next` last, and the remaining seams keep `signal` immediately before a waterfall's final `next`. `PreStepContext` and `RequestFailureContext` are retired, with their fields folded into the `agent/pre-step` and `agent/request-error` payloads ([payload-object events](2026-08-06-agent-event-payload-objects.md)). Pre-step entry, request configuration, request-error recovery, model generation, tool execution, approval, turn stopping, and subagent or workflow requests all receive the current signal. Hook bridges must also supply `RunHookOptions.signal`, so a turn cancellation reaches the bash executor's process-group kill and join boundary. `SystemPrompt.assemble()` carries `signal?: AbortSignal` in `AssembleContext` because that object is an explicit request value that can also represent signal-less assembly outside a turn. Listeners may cooperate with the signal but must not retain it to control another turn.

 A service is a plugin's only API surface toward other plugins (UI components and injection faces are not APIs; a plugin nobody calls mounts no service — ui-trajectory is the minimal-plugin exemplar: no ctx service, only view-slot registrations). The roster: `ctx.connection` (api client + stream handles), `ctx.slots` (registry wrapper emitting `slots/changed`, render entry, renderer install seam), `ctx.sessions` (list store, current-session state, scope tree), `ctx.loader`, `ctx.theme`, `ctx.i18n`, `ctx.layout` (cross-plugin view navigation), `ctx.conversation` (send/cancel/startSession). Viewing state that used to live in service stores (panel widths, selection, drafts) now lives in entry-declared stores per the [slot system standard](2026-07-22-slot-type-chain-implementation.md).
 
-There is no registration model besides slots — the former view and tool rings both dissolved into it. Conversation views are entries of the `'conversation.view'` list slot ui-conversation declares, tab metadata rides the registration options (`id`/`order`/`label`), and per-view chrome lives inside the view components themselves. Tool presentation crosses one explicit package boundary: ui-conversation places each ordered root call into the single `'conversation.chat.tool'` seat without interpreting Tool names or Code Dispatch topology; ui-tool selects `codeDispatches[rootCallId]` from the Runtime snapshot, renders that root/child shape, and declares the keyed/session `'tool.call.toolview'` child slot.

 **Scope addressing** mirrors the host's agent-scope idiom: services are root singletons whose methods take no sessionId — they read the caller's scope mark (`scopeOf(ctx)`). Inside a session scope, `ctx.conversation.send('hi', 'queue')` targets that session; cross-session calls re-target by switching ctx (`ctx.sessions.scope(id)!.conversation.send(...)`); calling a scoped method from root ctx throws. Client session scopes are minted like host agent scopes (a no-op plugin fiber + a scope-key extend), built lazily on first viewing and torn down only when the session is removed and unwatched — host-session death alone does not tear a scope (it freezes into a read-only viewport).

 ## Decision
 
-Tool is a first-class Client UI concept with one presentation owner, `@deepseek-ai/dsh-client-ui-tool`. Session Event, projection, fold, `ConversationSnapshot` construction and caching, historical paging, and Code Dispatch indexing remain unchanged.
+Tool is a first-class Client UI concept with one presentation owner, `@deepseek-ai/dsh-client-ui-tool`. Runtime normalizes Code Dispatch into recursive `ToolCallBlock` values: every root or child owns its next level through `subCalls`, and `ConversationSnapshot` exposes no separate parent-to-children map.
 
 “First-class concept” describes UI ownership only; it adds no Runtime data kind. `ConversationNode` remains the transcript projection, `ChatFlowItem` remains the render unit produced when conversation sorts and groups nodes, `ToolCallBlock` remains the standard data for one call, and `ToolCallTree` only composes root/subcall presentation within Tool. Command continues to render through the separate `'conversation.chat.commandview'` seat and does not become Tool.
 
 `ui-conversation` owns ordered placement. `deriveChatFlow()` still decides where a settled Tool group appears, and `ChatView` still appends running calls, maintains scroll anchors and selection, and supplies host actions. For each root call it renders the single/session `'conversation.chat.tool'` seat with the root block, selected call id, session cwd, and open-file/inspect callbacks. It does not read Code Dispatch children, branch on Tool names, or import Tool-specific views and card models.
 
-`ui-tool` occupies that whole-Tool seat. Through its standard session slot props, `ToolCallTree` selects the Runtime-projected `codeDispatches[rootCallId]` array, renders the root followed by that one currently supported child level, and routes both forms through one keyed/session `'tool.call.toolview'` child slot using `entryKey: toolName`. An absent business registration renders `GenericToolCard`. This is deliberately one-level composition, not a claim that the Runtime supports an arbitrary recursive call graph.
+`ui-tool` occupies that whole-Tool seat. `ToolCallTree` recursively walks the root block's `subCalls` and routes every level through one keyed/session `'tool.call.toolview'` child slot using `entryKey: toolName`. An absent business registration renders `GenericToolCard`. It neither reads Session nor maintains a second call topology.
 
 Business plugins register only atomic views against `'tool.call.toolview'`. Their owner payload is the standard Tool call block plus identity, cwd, and host actions; it carries no Session projector or conversation service. Skill remains an ordinary Tool and `ui-skill` registers the `skill` key through this seam. Existing first-party views live in `ui-tool` until a business package has a reason to own one independently.
 
 The details panel is a second Tool presentation site but not a call-tree owner. `ui-conversation` delegates its selected output body through the single/session `'conversation.details.tool'` seat; `ui-tool` renders the card-aware output and the seat fallback preserves raw result text when the plugin is absent. Card models therefore have one production owner without introducing a reverse implementation import.
 
-The Runtime remains the authority for Tool lifecycle and call topology. Code Dispatch stays a top-level official concept because it changes `codeDispatches` and parent/child identity; ordinary Tool business differences stay at the keyed presentation seam. This package boundary does not add a Tool projector/fold registry.
+The Runtime remains the authority for Tool lifecycle and call topology.

It recursively projects children onto root `ToolCallBlock` values and copies only the owning ancestor path when a child changes.

+# Agent Note: Latch wake-ups that land in the cancel-convergence window
+
+Status: implemented
+

+
+## Problem
+
+`Agent.cancel(cause, { keepInbox: true })` returns immediately after firing the abort signal, but the active driver may not have converged to `idle` yet: LLM stream teardown, tool cancellation, and the `turn/end` append all unwind asynchronously after `abort()` returns. A waking send arriving in that window was placed into `next-turn` while `wakeDriver()` returned early on the still-`running` phase, and the exiting driver never replayed the wake — the message stayed parked until another waking send arrived. The same dropped-wake window existed around aborted `runMaintenance` activities. Several tests enshrined the parked behavior ("waits for another wakeup"); the bug broke both `session.cancel` and the `subagent.interrupt` composition path (issue #1838). The owning cancellation and send contracts are the [explicit turn cancellation](../architecture/2026-07-16-explicit-turn-cancellation.md) and [unified send](../architecture/2026-07-22-unified-send-and-coalesced-user-messages.md) decisions; the production `keepInbox` consumer is [web stop preserves queue](2026-07-31-web-stop-preserves-queue.md).
+
+## Decision
+
+The `running` phase carries a `wakeRequested` latch, mirroring the existing `maintenance` phase field. `wakeDriver()` latches whenever the current activity cannot deliver the wake — a maintenance task never reads the queue, and an aborted activity converges without restarting — while a live driver needs no latch because it claims queued work itself. The exiting activity replays the latch at its own convergence boundary (`kick`'s `finally` and `runMaintenance`'s `finally`): this placement guarantees `turn/end N` lands before the replayed driver opens `turn/start N+1`, and that `whenIdle()` sees the replayed driver through its `activityDone` loop. The replay sites run only while `inbox.hasPending`, so a latched wake removed from the inbox before convergence does not start an empty driver. A wake sent while the agent is already idle keeps its turn boundary even when its message is cleared before the driver claims — that `idle → running → idle` transition is an observable contract: the goal-session driver's pause/disarm fallback fires on the `idle` transition after a cancelled reservation (CI caught this when the guard was moved into `wakeDriver()` and suppressed the boundary). `cancel()` without `keepInbox` clears the latch together with the inbox.
+
+The `signal.aborted` discriminator is load-bearing: it separates pre-abort queued work — which `keepInbox` parks for a later wake (acceptance criterion 1) — from post-abort explicit wakes, which must run after convergence.
+
+## Alternatives considered
+
+**Have `cancel()` set the phase to `idle` immediately.** Rejected: the driver is still unwinding, so this overlaps two drivers. The replay lives in the old driver's `finally`, which then never runs — 14 of 83 tests failed, several deadlocked. Repairing it requires identity-based phase ownership plus a turn-open quiescence barrier, which is strictly more machinery and is the latch in disguise.
+
+**Latch unconditionally for every non-idle wake.** Rejected: pre-abort wakes would auto-start after a `keepInbox` cancel, violating acceptance criterion 1; the "parks queued work" test and the error-window steering test both failed.
+
+**Replay through a chained promise (`activityDone.then(...)`).** Rejected: the replay would run outside the activity's own settlement, so `whenIdle()`'s loop can resolve before the replayed driver starts; fixing that requires replacing `activityDone` at send time and depends on microtask reaction ordering — more fragile than a synchronous flag.
+
+**Wait for quiescence in the subagent adapter.** Rejected by the issue scope: the cancel/wake state machine owns the fix, not a consumer.
+
+## Consequences
+
+The `running` phase gains a `wakeRequested` field; `cancel()` without `keepInbox` clears it alongside the inbox, and a `disposed` cancel never latches, so a wake landing after disposal begins stays parked and `whenIdle()` does not wait on a full model turn over the session being torn down. A wake arriving in the sub-microtask gap between the driver's final `hasPending` check and its exit still parks — no latch fires because the phase is `running` and not aborted; closing that gap requires the unconditional latch and is deliberately out of scope. Between the aborted turn and the replayed driver, status transitions emit a transient `idle → running` pair. A waking send whose message is cleared before any driver claims it still opens an empty completed turn, preserving the observable wake boundary.

+# Agent Note: 锁存取消收敛窗口内到达的唤醒请求
+
+Status: implemented
+
+[English](2026-08-07-cancel-convergence-wake-latch.md) | 中文
+
+## 问题
+
+`Agent.cancel(cause, { keepInbox: true })` 在触发 abort 信号后立即返回，但活动 driver 可能尚未收敛到 `idle`：LLM 流拆除、工具取消与 `turn/end` 落盘都会在 `abort()` 返回后异步展开。在该窗口内到达的唤醒 send 被放入 `next-turn`，而 `wakeDriver()` 对仍处于 `running` 的 phase 直接返回，退出的 driver 也从不重放这次唤醒——消息会一直停放到下一条唤醒 send 到达。被中止的 `runMaintenance` 活动周围也存在同样的唤醒丢失窗口。多个测试固化了停放行为（「等待下一次唤醒」）；该缺陷同时破坏了 `session.cancel` 与 `subagent.interrupt` 组合路径（issue #1838）。拥有取消与发送契约的既有决策是[显式轮次取消](../architecture/2026-07-16-explicit-turn-cancellation.md)与[统一发送](../architecture/2026-07-22-unified-send-and-coalesced-user-messages.md)；生产环境中的 `keepInbox` 消费方是[Web 停止保留队列](2026-07-31-web-stop-preserves-queue.md)。
+
+## 决策
+
+`running` phase 携带 `wakeRequested` 锁存，与既有的 `maintenance` phase 字段对称。`wakeDriver()` 在当前活动无法投递唤醒时锁存——maintenance 任务从不读取队列，被中止的活动收敛后不会重启——而存活的 driver 不需要锁存，因为它自己会认领排队的工作。退出中的活动在其自身收敛边界（`kick` 的 `finally` 与 `runMaintenance` 的 `finally`）重放锁存：这一位置保证 `turn/end N` 先于重放 driver 打开 `turn/start N+1` 落盘，并保证 `whenIdle()` 通过其 `activityDone` 循环看到重放 driver。两个重放点仅在 `inbox.hasPending` 时执行，因此收敛前被从 inbox 移除的锁存唤醒不会启动空 driver。而 agent 已处于 idle 时发送的唤醒，即使消息在 driver 认领前被清除，仍会打开自己的 turn 边界——这趟 `idle → running → idle` 转换是可观察契约：goal-session driver 的 pause/disarm 回退依赖取消预订后的 `idle` 转换触发（把守卫放进 `wakeDriver()` 后该边界被抑制，CI 发现了这一点）。不带 `keepInbox` 的 `cancel()` 会连同 inbox 一起清除锁存。
+
+`signal.aborted` 判别项是承重的：它区分「中断前已排队的工作」——`keepInbox` 将其停放以待后续唤醒（验收条件 1）——与「abort 后显式的唤醒」，后者必须在收敛后执行。
+
+## 备选方案
+
+**让 `cancel()` 立即把 phase 置为 `idle`。** 不予采用：driver 仍在展开收尾，这会重叠两个 driver。重放逻辑位于旧 driver 的 `finally`，而该 `finally` 此后不再执行——83 个测试中有 14 个失败，多个死锁。修复它需要基于身份的 phase 所有权外加 turn 打开时的 quiescence 屏障，机制上严格更重，而且该屏障就是换了个形态的锁存。
+
+**对每个非 idle 唤醒无条件锁存。** 不予采用：中断前的唤醒会在 `keepInbox` 取消后自动启动，违反验收条件 1；「停放排队工作」测试与错误窗口的 steering 测试双双失败。
+
+**通过链式 promise（`activityDone.then(...)`）重放。** 不予采用：重放会运行在活动自身结算之外，`whenIdle()` 的循环可能在重放 driver 启动前就 resolve；修复它需要在 send 时同步替换 `activityDone`，并依赖微任务反应顺序——比同步 flag 更脆弱。
+
+**在 subagent adapter 中等待 quiescence。** 被 issue 范围否决：修复由取消/唤醒状态机拥有，而不是消费方。
+
+## 影响
+
+`running` phase 新增 `wakeRequested` 字段；不带 `keepInbox` 的 `cancel()` 会连同 inbox 一起清除它，且 `disposed` 取消从不锁存——dispose 开始后到达的唤醒保持停放，`whenIdle()` 不会在拆除中的会话上等待一个完整模型 turn。落在 driver 最后一次 `hasPending` 检查与退出之间微任务间隙的唤醒仍会停放——没有锁存触发，因为 phase 是 `running` 且未 abort；关闭该间隙需要无条件锁存，刻意留作范围外。在被中止的 turn 与重放 driver 之间，状态转换会发出一次瞬态 `idle → running` 对。唤醒 send 的消息在任何 driver 认领前被清除时，仍会打开一个空的 completed turn，保留可观察的唤醒边界。

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 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.

+English | [中文](2026-08-07-web-inline-file-mentions.zh.md)
+
+> Scope: linking inline-code tokens in the closing message's prose to the files the turn produced. Not in scope: recognizing paths in plain prose, linking files the turn did not produce, and mentions in streaming or mid-turn messages.
+
+## Problem
+
+The produced-files row lists a turn's output, but the closing message usually also *names* the file in prose — as inline code, like `` `deepseek-homepage.html` `` — and that mention was inert text. The reader's eye lands on the sentence first; the affordance sat one row below it.
+
+## Decision
+
+**A prose mention links only when it matches a produced file.** The [produced-files decision](2026-07-31-web-workspace-file-links.md) rejected linkifying the closing message because rendering must not depend on the model spelling a path recognizably; that holds. The row remains the authoritative, prose-independent account. This feature adds a second consumer of the same `locations` vocabulary: `producedFileMentions` resolves an inline-code token by exact path, or by being exactly the basename of exactly one produced path. A basename two paths share stays inert rather than guessing, and a token naming nothing the turn wrote stays inert — a mention link can never 404.
+
+**The renderer owns no vocabulary, and the provider is the deliverables plugin.** `MarkdownText` takes an optional `MarkdownFileMentions` resolver and consults it for inline-code tokens — after URL promotion, which wins, and never inside an anchor, where a button cannot nest. What names a file is decided behind the optional `chatFileMentions` service ui-conversation reaches via `ctx.get`: ui-deliverables provides it beside its turn-tail chain entry, so one cordis.yml line composes the row and the prose links in or out together, and ui-primitives gains no session concepts. Mentions apply to settled renders only — the streaming cache must not bake in handlers that could go stale, and the vocabulary is not final until the turn closes. The consumer memoizes the resolver on the closing seq rather than the growing transcript, so a settled message's cached parse survives stream appends.
+
+## Alternatives considered
+
+- **Path-shaped regex over all prose** — links `package.json` mentioned abstractly and examples that were never written; every false positive is a click that opens nothing or the wrong file. The vocabulary approach cannot produce a dead link.
+- **Linking suffix matches (`out/index.html` mentioned as `index.html` in a subdirectory listing)** — deferred; exact path and unique basename cover the observed closing-message shapes, and a wider matcher can loosen later without breaking the seam.
+- **Resolving in ui-primitives against a passed path list** — puts matching policy in the generic renderer, where other consumers would inherit it unasked. The resolver seam keeps policy with the owner.
+- **Threading the vocabulary through the turn-tail chain** — the chain is a render dispatch below the message; mentions decorate markdown inside it, which only data reaching MarkdownText can do. The optional service is that data path, and its absence is the off state.
+
+## Consequences
+
+The mention and the row are two affordances for one fact (full path as `title` on both); the mention itself wears the markdown sheet's anchor language — link-blue at rest, hover underline — because an at-rest underline collides with monospace descenders inside the code chip. `apps/web/tests/produced-file-mentions.e2e.ts` pins the assembled behavior with a built write-turn seed: unique basename links, ambiguous and unknown tokens stay inert; it does not click, for the produced-files restraint (the opener launches a real application). Mentions in mid-turn narration stay inert even for files the turn later produces, because the vocabulary attaches to the closing message only. The window-prepend edge — a window that starts mid-turn later gaining earlier same-turn writes — leaves a mention unlinked until remount, never wrongly linked.

+
+**渲染器不持有词表，提供方是 deliverables 插件。**`MarkdownText` 接受可选的 `MarkdownFileMentions` 解析器，对行内代码 token 询问它——URL 提升优先于解析器，且绝不在锚点内部（按钮不能嵌套在链接里）。什么算文件名的决定藏在 ui-conversation 经 `ctx.get` 触达的可选 `chatFileMentions` service 背后：ui-deliverables 在其 turn-tail chain 注册项旁提供该 service，因此 cordis.yml 中的一行同时把产物行和正文链接组合进来或去掉，ui-primitives 不引入任何会话概念。提及只作用于已定稿的渲染——流式缓存不能烘进可能过期的 handler，而且词表在轮次收尾前并不最终。消费方按收尾 seq 而非不断增长的 transcript 记忆化解析器，因此已定稿消息的缓存解析在流式追加中得以保留。
+
+## 考虑过的替代方案
+
+- **对全部正文跑路径形状的正则**——会把随口提到的 `package.json` 和从未写过的示例都链接上；每个误报都是一次打开空无或错误文件的点击。词表方案不可能产生死链。
+- **链接后缀匹配（子目录列表里把 `out/index.html` 写作 `index.html`）**——暂缓；精确路径加唯一 basename 已覆盖观察到的收尾消息形态，之后放宽匹配器不会破坏这道 seam。
+- **在 ui-primitives 里对传入的路径列表做解析**——把匹配策略放进通用渲染器，其他消费方会被动继承。解析器 seam 让策略留在持有者手里。
+- **经由 turn-tail chain 传递词表**——chain 是消息下方的渲染派发；提及要装饰的是消息内部的 markdown，只有抵达 MarkdownText 的数据才做得到。可选 service 就是那条数据通路，它的缺席即关闭态。
+
+## 后果
+
+提及与产物行是同一事实的两个交互面（两者都以完整路径作 `title`）；提及本身采用 markdown 样式表的锚点语言——静止为链接蓝、悬停出下划线——因为静止下划线在 code 胶囊里会压住等宽字的下伸部。`apps/web/tests/produced-file-mentions.e2e.ts` 用构造的写入轮 seed 钉住组装后的行为：唯一 basename 成链，歧义与未知 token 保持死文本；它不驱动点击，沿用产物行的克制（opener 会启动真实应用）。轮次中途叙述里的提及即使命名了本轮后来产出的文件也保持死文本，因为词表只挂在收尾消息上。窗口前插的边界——从轮次中途开始的窗口后来补入了同轮更早的写入——只会让提及在重挂载前暂不成链，绝不会错链。

+# Agent Note: Browser GIFs preserve one evidence chain
+
+Status: implemented
+
+English | [中文](2026-08-08-browser-gif-evidence-chain.zh.md)
+
+## Problem
+
+A browser-demo storyboard can contain individually truthful screenshots without proving one truthful execution. Reusing global application state can admit old settings or sessions, capture automation can accidentally combine frames from separate model runs, and a chat transcript can show a successful fallback without exposing the tool rejection that caused it. Fuzzy accessible-name matching can also accept prompt echoes or descendant text instead of the intended result.
+
+Headless production recording has two further boundaries. A product default may open a native operating-system surface that automation cannot drive, while replacing that surface with a mock or test hook would change the provenance. After publication, a successful git push does not prove that a private-repository GIF is fetchable or that GitHub recognizes the pull-request Markdown as an image.
+
+## Decision
+
+The [`record-browser-gif`](../../../skills/record-browser-gif/SKILL.md) workflow treats one storyboard as one evidence chain pinned to an exact pull-request head. Before building, it requires a clean worktree and records that commit SHA. Each run uses fresh `DSH_HOME`, `DSH_AGENTS_HOME`, workspace, session, and isolated browser state, and every published frame comes from the same server and model-backed scenario run. When a fresh browser context is unavailable, the exact origin's cookies and site storage are cleared before navigation. Existing user browser state is used only when requested or required, is declared in the provenance, and does not substantiate fresh client state. A failed capture run is discarded and repeated from fresh roots rather than combined with another run.
+
+Browser automation waits for unique, exact semantic states. When the claim concerns a tool call, rejection, or recovery, the storyboard includes a detail or trajectory frame that identifies the tool, shows its status or stable error code, and shows the downstream result. The final encoded GIF remains the verification subject; when a viewer cannot animate it, representative frames are decoded from that GIF instead of treating source screenshots as equivalent evidence.
+
+The available browser-control workflow remains preferred. When it is unavailable, the recorder uses the repository-declared Playwright dependency in an isolated headless browser rather than installing another driver or opening the user's browser. A native production surface may be replaced only through normal application configuration with an official browser-operable production backend, and that override is stated in the provenance. Fixtures, mock transports, synthetic events, and test-only hooks do not substantiate a real-production claim.
+
+Publication verifies the boundary again. The assets branch contains media only, the staged and published bytes match the verified artifact, and a private-repository asset is checked through authenticated API or raw requests for its path, byte size, checksum, response status, and media type. This proves the repository-member review path only; the [documentation-site image decision](2026-08-06-doc-site-carries-its-images.md) owns why a public site cannot depend on a private raw URL. Immediately before the pull-request body changes, the live head must still equal the recorded head. After the edit, the live head is checked again and must remain at that recorded value; GitHub's Markdown renderer separately must produce the expected image.
+
+## Alternatives considered
+
+**Allow frames from separate runs when their visible states look equivalent.** Visual similarity does not establish shared state, causal order, or one scenario execution. Re-recording costs another real round but preserves the claim the storyboard makes.
+
+**Use the chat transcript as sufficient proof of tool recovery.** A final answer proves that the task completed, but it can hide which tool ran, whether the failure was structured, and whether the model recovered from that failure. A trajectory or detail frame carries those facts directly.
+
+**Replace inaccessible native UI with a fixture or test hook.** That makes automation easier by changing the product path under observation. Selecting an official production backend through normal configuration keeps the exercised implementation real and makes the narrower mode explicit.
+
+**Trust a successful assets-branch push or an anonymous fetch.** A push proves only that git accepted bytes, while private repositories intentionally reject unauthenticated raw requests. Authenticated byte verification plus GitHub Markdown rendering tests the two publication boundaries that reviewers use.
+
+## Consequences
+
+GUI evidence now establishes one causal execution rather than a collage of plausible states, and reviewers can inspect both a structured tool failure and the completed result. Publication detects stale pull-request heads, corrupted or misplaced media, and invalid image Markdown before the body is treated as finished.
+
+The workflow spends additional scratch state, may repeat a real model round after a capture failure, and usually adds a detail frame plus authenticated publication checks. Headless recordings can use fewer production backends than an interactive desktop, and every such selection remains part of the stated provenance.

+浏览器演示的分镜可以由每张都真实的截图组成，却无法证明这些截图来自同一次真实执行。复用应用全局状态可能引入旧设置或旧会话；录制自动化可能误将不同模型运行的画面合并；聊天 transcript（文本记录）可能显示降级处理成功，却没有揭示触发降级的工具拒绝。按无障碍名称进行模糊匹配，还可能误把提示词回显或后代文本当成预期结果。
+
+无头模式下的生产环境录制还有两道边界。产品默认配置可能打开自动化无法操控的原生操作系统界面，而用 mock 或测试钩子替换该界面会改变证据来源。发布之后，git 推送成功也不能证明私有仓库中的 GIF 可以获取，或 GitHub 能将 PR（Pull Request）的 Markdown 识别为图片。
+
+## 决策
+
+[`record-browser-gif`](../../../skills/record-browser-gif/SKILL.md) 工作流将一套分镜视为一条证据链，并将其固定到精确的 PR head。构建之前，工作流要求工作树干净并记录其 commit SHA。每次运行都使用全新的 `DSH_HOME`、`DSH_AGENTS_HOME`、工作区、会话和隔离浏览器状态，所有发布帧均来自同一个服务器及同一次由模型驱动的场景执行。无法创建全新浏览器 context 时，应在导航之前清除该 origin 的 cookie 和站点存储。只有用户提出要求或确有必要时才能使用用户已有的浏览器状态；必须在证据来源中声明，并不得以此证明客户端状态全新。录制失败时，丢弃该次运行并从全新的状态根目录重新执行，不与另一次运行合并。
+
+浏览器自动化会等待唯一且精确的语义状态。如果需要证明工具调用、拒绝或恢复，分镜就必须包含详情帧或轨迹帧：标明工具、显示其状态或稳定错误码，并展示后续结果。最终编码出的 GIF 始终是验证对象；如果查看器无法播放动画，应从该 GIF 中解码出代表性帧，而不能将源截图视为等效证据。
+
+仍应优先使用已有的浏览器控制工作流。如果该工作流不可用，录制程序应在隔离的无头浏览器中使用仓库已声明的 Playwright 依赖，而不是安装其他驱动或打开用户的浏览器。只有通过正常应用配置选用官方且可由浏览器操作的生产后端，才能替换原生生产界面，并且必须在证据来源说明中注明这一覆盖。fixture（测试前置数据）、mock 传输层、合成事件和测试专用钩子均不能支撑真实生产实现的主张。
+
+发布环节会再次验证边界。资产分支只包含媒体文件，暂存和发布的字节必须与已验证产物一致；对于私有仓库中的资产，应通过经身份验证的 API 或原始内容请求，检查其路径、字节大小、校验和、响应状态和媒体类型。这只能证明仓库成员的评审访问路径；[文档站点图片决策](2026-08-06-doc-site-carries-its-images.md)解释了公共站点为何不能依赖私有的原始内容 URL。修改 PR 正文之前，必须再次确认在线 head 仍与录制时的 head 相同。编辑后还要再次检查在线 head，且它必须保持为该记录值；GitHub 的 Markdown 渲染器则须单独生成预期图片。
+
+## 曾考虑的替代方案
+
+**只要可见状态看起来等价，就允许使用不同运行的画面。**视觉相似不能证明各画面共享同一状态、具有因果顺序或来自同一次场景执行。重新录制需要再执行一次真实模型场景，但能维持整套分镜所表达的主张。
+
+**将聊天 transcript 视为工具恢复的充分证据。**最终答案能证明任务已经完成，却可能隐藏调用了哪个工具、失败是否为结构化失败，以及模型是否从该失败中恢复。轨迹帧或详情帧可以直接承载这些事实。
+
+**使用 fixture 或测试钩子替换无法访问的原生 UI。**这种做法通过改变被观察的产品路径来简化自动化。通过正常配置选用官方生产后端，既能保持受测实现真实，也能明确表述所采用的较窄运行模式。
+
+**相信资产分支推送成功或匿名请求成功。**推送只能证明 git 接受了相应字节，而私有仓库会有意拒绝未经身份验证的原始内容请求。经身份验证的字节校验与 GitHub Markdown 渲染验证，覆盖了评审者实际使用的两道发布边界。
+
+## 后果
+
+GUI 证据现在能证明一次具有因果关系的执行，而不是将若干可信状态拼成集合；评审者既可以检查结构化的工具失败，也可以检查最终完成的结果。在 PR 正文被视为完成之前，发布验证可以发现陈旧的 PR head、损坏或位置错误的媒体文件，以及无效的图片 Markdown。
+
+该工作流会占用额外的临时状态；录制失败后，可能需要重新执行一次由真实模型驱动的场景；通常还会增加一张详情帧和经身份验证的发布检查。相比交互式桌面，无头录制可使用的生产后端更少；每次选择这类后端时，都必须将其写入证据来源说明。

 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.
+1. Require a clean worktree, record its exact commit with `git rev-parse HEAD`, then build that recorded tree — here, `pnpm run build && pnpm run build:web`. A GIF recorded against another commit's build misattributes the evidence.
+2. Boot one server per port from that tree with fresh scratch `DSH_HOME`, `DSH_AGENTS_HOME`, workspace, and session state. Give the browser a fresh isolated context or profile as well; if the browser workflow cannot create one, clear that origin's cookies and site storage before navigation so persisted client state cannot affect the evidence. Source the root `.env` for the API key through the application's normal path; never echo the key.
+3. Treat one storyboard as one evidence run: every published frame comes from that server and those state roots, workspace, session, and model-backed scenario run. If capture automation fails, discard its frames and rerun from fresh roots; never splice frames from separate runs.
 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; state that exception in the provenance and do not claim fresh client state. If browser control is unavailable, use the repository-declared Playwright dependency in an isolated headless browser; do not install another driver or launch the user's browser. State that fallback in the provenance.
 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 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-<label>`); writing into a missing directory fails with ENOENT at capture time.
-6. 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.
-7. Make completion predicates match an exact-text element — for example, an element whose trimmed text equals the expected reply — never a substring check such as `body.textContent.includes(...)`, which the echo of the user's own prompt also satisfies.
-8. Capture a transient state (spinner, running row) by driving a slow foreground operation — for example, a `sleep 15` bash command — and polling a concrete DOM marker (a `data-*` attribute) inside one browser-script call that also takes the screenshot. State polled across separate tool calls is lost, because the turn settles between calls.
-9. Engineer the prompt so the state you need actually occurs: instruct the model to wait in the foreground when it would otherwise background a slow command, and give it a settle sentinel such as "reply with the single word done" to anchor the completion predicate.
-10. Capture no secrets, personal data, unrelated tabs, or transient notifications. Stop any unnecessarily long real-API run after the demonstrated state is visible.
+3.

Require the locator to resolve exactly one element; for Playwright accessible-name locators, use `exact: true` when equality is intended because descendant text or a prompt echo can otherwise create a false match. Do not use a fixed delay as proof that the application reached the state.
+8. Make completion predicates match an exact-text element — for example, an element whose trimmed text equals the expected reply — never a substring check such as `body.textContent.includes(...)`, which the echo of the user's own prompt also satisfies.
+9. When the claim involves a tool call, rejection, or recovery, include a detail or trajectory frame that shows the tool identity, status or stable error code, and the downstream result. A chat-only outcome does not prove why the tool path behaved that way.

 Adapter selection, dispatch, and iteration failures become terminal error or aborted `finish` chunks. `agent/request-error` receives request coordinates, normalized `LlmFailure`, available retry policy, and signal; middleware and consumer errors remain outside recovery. Failed chunks commit neither messages nor tool calls.

+Other failures use `agent/error`; cancellation and disposal beat recovery.

Effective `cancel(cause)` reports its cause before clearing and aborting; idle calls emit nothing. Waking input that lands after the abort fires but before convergence runs at the driver's convergence boundary, while a `disposed` cancel leaves it parked ([cancel-convergence wake latch](../.agents/notes/implemented/bug-fix/2026-08-07-cancel-convergence-wake-latch.md)). Durability distinguishes `aborted` cancellation from `disposed` teardown, which awaits quiescence ([decision](../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md)).
 
 Turn and step events are turn-enclosed; the loop appends `user/message` events only from entered batches inside a turn. A turn opens before the initial claim and pre-step, so rejection, empty input, cancellation, or failure closes a durable turn without any step events. Standalone `compact/* { turn: null }` events consume no turn, and their lock-time markers may interleave with inbox splices. Reload synthesizes interrupted turn ends; `session/end-seed` distinguishes stale compaction orphans from live locks. After close, only `agent/error` reports failures. Each turn has one [TurnEndReason](core-data-structures/session.md#why-a-turn-ended-turnendreasonmap).

A `session/end-seed` boundary closes an unmatched compaction request as an error at the boundary time with `Compaction was interrupted before completion.`; a later start projects as an independent request instead of overwriting the orphan.
 
-## Code Mode sub-dispatch index
+## Code Mode child-call tree
 
-`ConversationSnapshot.codeDispatches` groups a `run_code` call's sub-dispatches under their parent callId, in start order, using the native call-block shapes: a `tool/code-dispatch-start` event lands the `RunningToolCall` form (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. A settle whose start fell outside the replay window appends directly with `callTime: null` (duration unknown — never a fabricated zero). Live mux frames and history replay build the identical index; sub-calls never join the transcript `nodes` flow; per-parent array and map references are memo-stable across unrelated snapshot swaps.
+Every `ToolCallBlock` recursively owns its children through `subCalls`, in start order. Runtime's `ToolCallTree` privately maintains the parent-callId-to-children index: a `tool/code-dispatch-start` event lands as a `RunningToolCall`, and the matching `tool/code-dispatch` settlement replaces it in place with a `ToolResultNode` whose `callTime` comes from the paired start. When the start fell outside the replay window, the settlement appends directly with `callTime: null`; Runtime never fabricates a zero duration. Live mux frames and history replay share this fold and tree projection, and child calls never become independent roots in transcript `nodes`. A child update copies only its ancestor path to the owning root; unchanged siblings and other roots retain object identity. Wire or history edges that would introduce a cycle or exceed the fixed 256-call recursive-depth safety limit are consumed without mutating the tree, so the rest of the session remains renderable.

 `SessionHistoryInspection.requests` 是一条按时间顺序排列、以用途为判别字段的提供方请求流。助手请求始终携带数值型 `turn` 与 `step`；压缩请求携带 `step: 0`，其 `turn` 所有者可以是 `null`。这个 null 所有者表示手动压缩独立运行在两个轮次之间，并不表示它属于任一相邻轮次。`session/end-seed` 边界会在边界时刻将未匹配的压缩请求以错误状态结束，错误固定为 `Compaction was interrupted before completion.`；后续 start 会投影为独立请求，而不会覆盖这项遗留的未匹配请求。

-`ConversationSnapshot.codeDispatches` 按父调用的 callId 和启动顺序，用原生调用块形状组织一个 `run_code` 调用的子调用：`tool/code-dispatch-start` 事件落成 `RunningToolCall` 形状（行组件从该形状推导运行中的转圈状态），其 `tool/code-dispatch` 完结事件原位替换为 `ToolResultNode` 形状，`callTime` 携带成对 start 事件的时间。start 落在回放窗口之外的完结事件则直接追加，`callTime: null`（耗时未知——绝不伪造零耗时）。live mux 帧与历史回放构建相同的索引；子调用永不进入 transcript 的 `nodes` 流；无关快照交换不会改变每个父调用对应的数组引用和映射引用，两者均保持 memo 稳定。
+每个 `ToolCallBlock` 都通过 `subCalls` 按启动顺序递归拥有自己的子调用。Runtime 的 `ToolCallTree` 私下维护 parent callId 到 child 的索引：`tool/code-dispatch-start` 事件落成 `RunningToolCall`，对应的 `tool/code-dispatch` 完结事件原位替换为 `ToolResultNode`，其 `callTime` 来自成对 start 事件；start 落在回放窗口之外时，完结事件会以 `callTime: null` 直接追加，绝不伪造零耗时。live mux 帧与历史回放共用这套 fold 和树投影；子调用不会成为 transcript `nodes` 中的独立 root。一次 child 变化只会复制从该 child 到所属 root 的祖先链，未变化的 sibling 和其他 root 保持对象引用稳定。会引入环，或使递归深度超过 256 个调用这一固定安全上限的协议或历史记录边会被视为已消费，但不会修改树，因此会话其余部分仍可渲染。

 `src/client/` is organized by domain. `contract/` is the shared face for slot declarations, composed props, and cross-domain types; `skeleton/`, `chat/`, `input/`, `queue/`, and `settings/` keep their implementations internal, while `apply.ts` is their assembly point.

 `ProducedFiles` renders the row between the closing message's body and its IconActions footer: a quiet label, up to six chips (basename text, full path as the `title`), and an explicit remainder count past the cap. Each chip opens through the owner-supplied `openFile` — the same Host opener the tool rows use, with the chat view resolving relative paths against the session cwd. Design rationale: the [workspace file links Agent Note](../../../.agents/notes/implemented/feature/2026-07-31-web-workspace-file-links.md).
 
+The closing prose carries the same vocabulary. This plugin provides the `chatFileMentions` service the chat view consults per closing message: `producedFileMentions` resolves an inline-code token by exact path, or by being exactly the basename of exactly one produced path — a basename two paths share stays inert rather than guessing, so a mention link can never open the wrong file or 404. A resolved mention keeps its code chip and takes the markdown sheet's link language — link-blue at rest, underlined on hover, exactly like URL-promoted inline code — with the full path as its `title`; mentions never render inside anchors or streaming text. Decision record: the [inline file mentions Agent Note](../../../.agents/notes/implemented/feature/2026-08-07-web-inline-file-mentions.md).

 ## Known Limitations and Deferred Work
 
-- The Runtime currently exposes one level of Code Dispatch children. The renderer sends roots and children through the same atomic path, but it does not claim an arbitrary recursive wire topology.
+- The Host excludes `run_code` from Code Mode program bindings, so production events currently produce one dispatch level; the recursive Runtime/UI contract is ready for future nested producers.
 - Existing first-party Tool views are initially colocated here and can move to their owning business packages independently through the keyed slot.
 - Tool copy temporarily reuses the `ui-conversation` locale namespace.
