 The plugin owns a lifetime `AbortController` and tracks every active recovery callback, including delegated waterfall work and backoff. Effect cleanup first unregisters the listener, then aborts and awaits the active callbacks; abort wins over a late delegated retry decision, and a captured callback can neither retry nor enter the rest of its waterfall after disposal. This makes HMR disposal quiescent even though Cordis has already captured the listener.

The key sorts the code set and separates retry histories when a provider route is replaced by a behaviorally different same-mode policy.

 The listener calls `next()` for a non-transient code, an exhausted policy budget, or an over-cap provider delay. This preserves composition with context-overflow recovery and later policy plugins. For an owned failure it records and awaits the delay, then returns `{ kind: 'retry' }` without delegating. Turn cancellation and plugin disposal end the wait without returning a retry; the loop's cancellation/disposal checks remain authoritative.

UIs may render live chunks while a step is open, then mark or clear that transient view when `llm/retry` identifies the failed step or `turn/end` records failure. Web validates the complete retry payload contract, clears the failed partial at `llm/retry`, projects consecutive retry-turn events into one stable row updated to the latest attempt, and derives scheduled, started, or cancelled status from subsequent turn facts. Its countdown anchors the scheduled delay to browser receipt rather than the Host event clock, uses ceiling-rounded seconds with a one-second floor, animates only while unresolved, and keeps exact latest failure details collapsed behind the row. Retry nodes anchor their own trajectory turn even when the failed attempt has no assistant node. Message derivation continues to ignore the failed chunks, and Web applies the same projection during history rebuild so refreshing cannot resurrect discarded partials or duplicate retry rows.
 
 If recovery is exhausted, the final failure is stored once on `turn/end.reason` with the structured facts. If transient recovery continues, `llm/retry` is the durable home for that attempt's failure and delay. No standalone final-error event or response-id vocabulary is added.

+# Agent Note: Web diff card — the write/edit render intent reaches the browser
+
+Status: implemented
+
+English | [中文](2026-07-30-web-diff-card.zh.md)
+
+## Problem
+
+The `write` and `edit` tools declare `card: 'diff'` for both their call and their result ([render-intent union](../architecture/2026-07-02-tool-render-intent-union.md)): the call view carries the intended change derived from the arguments, and the result view carries the applied contextual hunks (`FileDiff[]`, computed by `packages/fs/tool-fs/src/diff.ts` and persisted in the result `meta` so replay reproduces it). That view already reaches the browser — host, connection, and runtime deliver it onto `ConversationSnapshot` as `callView`/`resultView` — and the TUI already renders it as per-file `+`/`-` blocks with a `+A -R · N file(s)` footer.
+
+The Web client ignored it. A write/edit call landed on `GenericToolCard`, whose row is derived from raw tool args, and the details panel flattened the result's content blocks into one `<pre>`. The `diffs` payload — the whole point of the result — was discarded, so a file mutation read as a one-line confirmation with no visible change.
+
+This is the [terminal card](2026-07-28-web-terminal-card.md) done for the `diff` arm: that change made the Web client a consumer of the `terminal` render intent; this one makes it a consumer of the `diff` render intent, reusing the same four-layer shape.
+
+## Decision
+
+`DiffBlock` is a `ui-primitives` component that renders a file mutation as an inline diff surface, and both Web render sites for a write/edit call consume the diff render intent through it: the chat tool row's body and the details panel's Output section. `ui-conversation/src/client/contract/diff-card-model.ts` is the single place that turns the snapshot's `callView`/`resultView` pair into the component's props, so the two sites cannot disagree about a change. It returns null — the generic path — whenever neither side declares `card: 'diff'`, including a `card` value this client version does not know, and whenever a settled call's result view is generic, which is how write/edit keep their execution errors on the generic path. The result side is authoritative once the call settles: the applied hunks replace the call-time diff derived from the arguments alone. A paging window that drops the call head still renders, because the result view carries the whole change.
+
+The component's contract follows the TUI's `diffLines` (`packages/ui/tui/src/components/transcript.ts`) so a diff reads the same shape across front ends:
+
+- **One path header per file.** A new file opens a bold path header; a same-file second hunk (a scattered edit, or a `replace_all`) opens with a `⋯` gap instead of repeating the path. The `N file(s)` footer counts DISTINCT paths on both front ends — this PR moved the TUI footer off `diffs.length` onto the distinct-path count, so two hunks in one file read as `1 file` in both.
+- **The change in the diff's own colors.** A removed line is `- ` on the error token, an added line is `+ ` on the success token, drawn verbatim with `white-space: pre` inside a horizontally scrolling box — a source line is read by its indentation, so it scrolls rather than folds. A create (`oldText: null`) has no removed side.
+- **Height cap with an expand control.** A diff longer than `DEFAULT_DIFF_MAX_LINES` (16) shows `ceil(max/2)` head rows plus the remaining tail rows, with a button between reporting the hidden count. The split arithmetic matches `TerminalBlock` and the TUI's collapsed card, so a long diff's head and tail slices agree across front ends.
+- **Line terminator.** A side's content splits on `\n` under the terminator rule `TerminalBlock` uses: empty text is zero lines (a full deletion's `newText`, a create's absent `oldText` side), a single trailing newline terminates its last line rather than adding a phantom empty one, and an interior blank line survives. This PR applied the same rule to the TUI diff branch, so the `+A -R` footer counts agree on both front ends for the newline-terminated content real write/edit calls carry.
+- **Footer and copy.** A dim `└ +A -R · N file(s)` footer summarizes the change; `+A -R` are the added/removed line counts, the same per-side counts the TUI footer draws. The copy control copies the prefixed diff text (path headers, `- `/`+ ` lines, the `⋯` gap), so a multi-file copy stays attributable.
+
+Geometry, radius, and fonts mirror `CodeBlock`/`TerminalBlock` so a diff card, a terminal card, and a fenced block read as one family; `white-space: pre` plus horizontal scroll is the deliberate divergence. The copy control floats in the card's top-right corner rather than on a banner row of its own, because a banner carrying only a copy button drew an empty band above the first diff line — the TUI diff card has no banner either, only the footer.
+
+The chat row renders the diff resident under its path-link summary, capped at `CHAT_DIFF_MAX_LINES` (8) against the panel's 16 — the same inline-output decision and the same in-flow-vs-reading-surface split recorded for the [terminal card](2026-07-28-web-terminal-card.md#inline-output-in-the-chat-row-reverses-a-stated-convention). A write/edit row is single-file, so its summary stays an openable path link AND its diff card expands; the two coexist because the card is not the path's args body.
+
+## Alternatives considered
+
+**A side-by-side (two-column) diff.** Rejected for now by the owner: it is denser but does not fit the narrow chat row, and the goal was parity with the TUI's single-column unified form. A two-column mode in the details panel is a later props change, not a redesign.
+
+**Git-style line-number gutters.** The `FileDiff` contract carries only `{ path, oldText, newText }` — `structuredPatch`'s hunk start lines are dropped in `diff.ts`, so no line number reaches the client. Rendering a numbered gutter needs a backend contract change (carry `oldStart`/`newStart`) and a matching TUI upgrade to stay consistent; deferred so this PR stays a pure Web consumer of the existing contract.
+
+**Reuse `CodeBlock`.** Rejected for the same reason the terminal card was: `CodeBlock` soft-wraps and has no per-line `+`/`-` role, no path headers, and no footer. The two share geometry and font tokens, which is the only part where one implementation is correct for both.
+
+## Consequences
+
+`DiffBlock` reads only the diff view's fields, so it stays a pure function of what the render intent carries — replay-safe like the presenters that produce the view. A UI without the diff capability still gets the bridge's generic fallback; nothing about the tool's result shape changed. No new runtime dependency: unlike the terminal card's `anser`, a diff needs no parser.
+
+The multi-file arm of `DiffBlock` (one card, several path headers) has no producer today: `write`/`edit` each mutate one file per call, so a real card shows one file with one or more hunks. The arm is built and tested for a future multi-file mutation tool, not for a current consumer.
+
+## Testing
+
+`packages/client/ui-primitives/tests/diff-block.spec.tsx` pins the component: the create arm (added-only, no removed side), the edit arm (removed above added), the same-file `⋯` gap versus a new file's own header, the empty-diffs null render, the footer counts and their singular/plural, the head/tail cap with its `aria-expanded` toggle, and the copy control asserting the prefixed diff text on both the accepted and refused clipboard paths. Per-file 100%.
+
+`packages/client/ui-conversation/tests/diff-card.spec.tsx` pins the wiring at every render site: `diffCardModel`'s derivation and each of its null arms, the result hunks replacing the call-time diff, a window-truncated call still rendering from the result, the chat row's diff body, `FileMutationRow`'s resident card and its path link opening cwd-resolved through the host, its registration under both `write` and `edit`, and the panel's Output section.
+
+The fixture (`packages/client/connection/src/client/fixture.ts`) carries three diff turns so a `?fixture` server and the per-package wiring suite exercise all three arms at both render sites: a single-hunk edit (turn 62, keyed `FileMutationRow`), a create/write (turn 63), and a multi-hunk edit (turn 67, the `⋯` gap between two scattered hunks in one file). The built-boot snapshot (`apps/web/tests/built-boot.snapshot.ts`) is a boot-assembly smoke that asserts only that the graph mounts and reaches chat content (`data-sample="bash-global"`); by its own contract it carries no diff-behavior assertions, which the wiring suite owns.

+# Agent Note: Web diff 卡片 —— write/edit 渲染意图抵达浏览器
+
+Status: implemented
+
+[English](2026-07-30-web-diff-card.md) | 中文
+
+## Problem
+
+`write` 和 `edit` 工具为其 call 和 result 都声明了 `card: 'diff'`（[render-intent union](../architecture/2026-07-02-tool-render-intent-union.md)）：call view 携带从参数推导的预期改动，result view 携带已应用的上下文 hunk（`FileDiff[]`，由 `packages/fs/tool-fs/src/diff.ts` 计算，并持久化在 result `meta` 中以便回放重建）。该视图早已抵达浏览器 —— host、connection、runtime 将它作为 `callView`/`resultView` 投递到 `ConversationSnapshot` —— TUI 也已将其渲染为按文件分组的 `+`/`-` 块加 `+A -R · N file(s)` 页脚。
+
+Web 客户端忽略了它。write/edit 调用落到 `GenericToolCard`，其行从原始工具参数推导，详情面板把 result 的 content block 摊平进一个 `<pre>`。`diffs` 载荷 —— result 的全部意义 —— 被丢弃，于是一次文件改动读起来只是一行确认、看不到任何改动。
+
+这是把 [terminal 卡片](2026-07-28-web-terminal-card.md) 对 `diff` 这一支重做一遍：那次改动让 Web 客户端成为 `terminal` 渲染意图的消费者；这次让它成为 `diff` 渲染意图的消费者，复用同一套四层结构。
+
+## Decision
+
+`DiffBlock` 是一个 `ui-primitives` 组件，把文件改动渲染为内联 diff 表面，write/edit 调用的两个 Web 渲染点都通过它消费 diff 渲染意图：chat 工具行的行体和详情面板的 Output 区。`ui-conversation/src/client/contract/diff-card-model.ts` 是唯一把快照的 `callView`/`resultView` 对转成组件 props 的地方，因此两个渲染点不会对一次改动产生分歧。当两侧都未声明 `card: 'diff'` 时它返回 null —— 走通用路径 —— 包括本客户端版本不认识的 `card` 值，以及已结算调用的 result view 是 generic 的情况（write/edit 的执行错误正是这样留在通用路径上的）。调用结算后 result 侧是权威：已应用的 hunk 替换仅从参数推导的 call 时 diff。分页窗口丢弃了 call 头也仍能渲染，因为 result view 携带完整改动。
+
+组件的契约遵循 TUI 的 `diffLines`（`packages/ui/tui/src/components/transcript.ts`），使 diff 在两个前端读起来是同一形态：
+
+- **每个文件一个路径头。** 新文件开启一个粗体路径头；同文件的第二个 hunk（分散编辑，或 `replace_all`）以一个 `⋯` gap 开启，而非重复路径。`N file(s)` 页脚在两个前端都统计**去重后的路径数** —— 本 PR 把 TUI 页脚从 `diffs.length` 改为去重路径计数，因此同文件两个 hunk 在两端都读作 `1 file`。
+- **改动用 diff 自身的颜色。** 删除行是 error token 上的 `- `，新增行是 success token 上的 `+ `，在横向滚动的盒子里以 `white-space: pre` 逐字绘制 —— 源码行靠缩进阅读，所以滚动而不折行。新建（`oldText: null`）没有删除侧。
+- **高度上限带展开控件。** 长于 `DEFAULT_DIFF_MAX_LINES`（16）的 diff 显示 `ceil(max/2)` 个头部行加剩余尾部行，中间一个按钮报告隐藏行数。分割算术与 `TerminalBlock` 和 TUI 的折叠卡片一致，因此长 diff 的头尾切片在两个前端一致。
+- **行终止符。** 每一侧的内容按 `TerminalBlock` 的终止符规则在 `\n` 上切分：空文本是零行（整文件删除的 `newText`、新建缺失的 `oldText` 侧），单个结尾换行终止其最后一行而非新增一条幻影空行，内部空行保留。本 PR 把同一规则应用到了 TUI diff 分支，因此对于真实 write/edit 调用携带的以换行结尾的内容，两个前端的 `+A -R` 页脚计数一致。
+- **页脚与复制。** 暗色 `└ +A -R · N file(s)` 页脚概括改动；`+A -R` 是新增/删除行数，与 TUI 页脚绘制的每侧计数相同。复制控件复制带前缀的 diff 文本（路径头、`- `/`+ ` 行、`⋯` gap），使多文件复制保持可归属。
+
+几何、圆角、字体镜像 `CodeBlock`/`TerminalBlock`，使 diff 卡片、terminal 卡片、代码块读起来是一家；`white-space: pre` 加横向滚动是刻意的分歧。复制控件浮在卡片右上角，而非占据自己的 banner 行，因为只放一个复制按钮的 banner 会在第一行 diff 上方画出一条空带 —— TUI 的 diff 卡片也没有 banner，只有页脚。
+
+chat 行把 diff 常驻渲染在路径链接摘要之下，上限 `CHAT_DIFF_MAX_LINES`（8），对应面板的 16 —— 与 [terminal 卡片](2026-07-28-web-terminal-card.md#inline-output-in-the-chat-row-reverses-a-stated-convention)记录的内联输出决策、以及流内表面对单调阅读表面的同一划分一致。write/edit 行是单文件的，所以它的摘要既是可打开的路径链接，其 diff 卡片又展开；两者共存，因为卡片不是路径的参数体。
+
+## Alternatives considered
+
+**并排（双栏）diff。** owner 目前拒绝：它更密但不适合狭窄的 chat 行，目标是与 TUI 单栏统一形式对齐。详情面板里的双栏模式是后续的 props 改动，不是重设计。
+
+**git 式行号槽。** `FileDiff` 契约只携带 `{ path, oldText, newText }` —— `structuredPatch` 的 hunk 起始行在 `diff.ts` 里被丢弃，所以没有行号抵达客户端。渲染行号槽需要后端契约改动（携带 `oldStart`/`newStart`）并同步升级 TUI 以保持一致；推迟，使本 PR 保持为对既有契约的纯 Web 消费。
+
+**复用 `CodeBlock`。** 因与 terminal 卡片相同的理由拒绝：`CodeBlock` 会折行，且没有每行 `+`/`-` 角色、没有路径头、没有页脚。两者共享几何与字体 token，那是唯一一处一个实现对两者都正确的部分。
+
+## Consequences
+
+`DiffBlock` 只读 diff view 的字段，因此它是渲染意图所携带内容的纯函数 —— 与产出该视图的 presenter 一样回放安全。没有 diff 能力的 UI 仍得到 bridge 的通用回退；工具的 result 形状没有任何改变。无新增运行时依赖：不同于 terminal 卡片的 `anser`，diff 不需要解析器。
+
+`DiffBlock` 的多文件支路（一张卡、多个路径头）今天没有生产者：`write`/`edit` 每次调用各改一个文件，所以真实卡片显示一个文件带一个或多个 hunk。该支路为将来的多文件改动工具而构建并测试，不是为当前消费者。
+
+## Testing
+
+`packages/client/ui-primitives/tests/diff-block.spec.tsx` 钉住组件：新建支路（只有新增、无删除侧）、编辑支路（删除在新增之上）、同文件 `⋯` gap 对比新文件自己的头、空 diffs 的 null 渲染、页脚计数及其单复数、头尾上限及其 `aria-expanded` 切换、以及复制控件在接受与拒绝两条剪贴板路径上断言带前缀的 diff 文本。Per-file 100%。
+
+`packages/client/ui-conversation/tests/diff-card.spec.tsx` 钉住每个渲染点的接线：`diffCardModel` 的派生及其每个 null 支路、result hunk 替换 call 时 diff、窗口截断的 call 仍从 result 渲染、chat 行的 diff 体、`FileMutationRow` 的常驻卡片及其路径链接经 host 以 cwd 解析打开、其在 `write` 与 `edit` 下的注册、以及面板的 Output 区。
+
+fixture（`packages/client/connection/src/client/fixture.ts`）携带三个 diff turn，使 `?fixture` 服务与 per-package 接线测试套件在两个渲染点演练全部三个支路：单 hunk 编辑（turn 62，keyed `FileMutationRow`）、新建/写入（turn 63）、多 hunk 编辑（turn 67，一个文件内两处分散 hunk 之间的 `⋯` gap）。built-boot snapshot（`apps/web/tests/built-boot.snapshot.ts`）是启动装配 smoke，只断言图挂载并抵达 chat 内容（`data-sample="bash-global"`）；按其自身契约它不带 diff 行为断言，那由接线套件负责。

+# Agent Note: Web result card frontend — rendering the web render intent in the browser
+
+Status: implemented
+
+English | [中文](2026-07-30-web-result-card-frontend.zh.md)
+
+## Problem
+
+The `web_search` and `web_fetch` tools declare a `card: 'web'` result view ([web result card](2026-07-30-web-result-card.md)): a `kind`-tagged union carrying either the structured cited sources plus an optional provider answer (`kind: 'search'`) or the fetched URL and its HTTP status (`kind: 'fetch'`). That view already reaches the browser — host, connection, and runtime deliver it onto `ConversationSnapshot` as `resultView` — but the Web client ignored it: a completed web call rendered only as its flattened model-facing text, the same lossy render the contract note explains the structured view exists to replace. A `web_search` reached the reader as one free-text markdown line per source rather than a citation list of clickable sources, and a `web_fetch` as its markdown body with no retrieval summary.
+
+## Decision
+
+`WebBlock` is a `ui-primitives` component that renders a completed web retrieval, and every Web render site for a web call consumes the `web` render intent through it: the keyed chat tool rows (`web_search`/`web_fetch`), the `GenericToolCard` render-site fallback, and the details panel's Output section. `ui-conversation/src/client/contract/web-card-model.ts` is the single place that turns the snapshot's `resultView` into the component's props, mirroring `terminal-card-model.ts`, so no two sites disagree about what a web call shows. It returns null — the generic path — for a running call (the web card is result-only, since the tools keep a generic pending view), for a settled call whose result view is not a web card including a `card` value this client version does not know (which arrives over the wire and so cannot be trusted to be a compiled variant), for a generic result view (a web tool's error path returns the generic card, whose text the generic path preserves), and for a web card whose `kind` this client version does not know (a newer host's value off the wire, which reading as a fetch would draw as an empty URL and `HTTP undefined`).
+
+One component draws both kinds, discriminated by `kind`. A `search` shows the answer as markdown above a citation list; each source is a safe external link labelled by its title, or its hostname when the provider gave none, with the snippet and publication date below it, and a `来源列表已截断` indicator when the tool capped the list. A `fetch` shows a compact summary: the linked final URL, its HTTP status, and a `内容已截断` indicator. One component rather than two because both are web retrieval rendered as one card family, which is exactly the reason the contract carries them under one `card` tag with a `kind` discriminant.
+
+**Links are safe by the http(s) subset of the allowlist MarkdownText applies to untrusted assistant-authored links** — MarkdownText also permits `mailto:`, deliberately excluded here since a retrieval URL is never a mail address. A source or fetch URL becomes a navigable anchor only when its protocol is `http:` or `https:`, with `target="_blank"` and `rel="noopener noreferrer"`; a `javascript:`/`data:`/`file:`/`mailto:` URL or an unparseable string renders as plain text with no href. The result content a web tool returns is model-authored and reaches this component unverified, so it is treated as untrusted exactly as assistant markdown is. The label falls back from title to hostname to the raw URL, so a source always reads as something even when both the title is absent and the URL does not parse.
+
+**Geometry mirrors CodeBlock/TerminalBlock** (12px radius, code-block surface, 16px vertical margin) so a web card reads as one family with them. A long source list caps at `maxSources` with a head/tail collapse using TerminalBlock's exact split arithmetic (`ceil(max/2)` head lines plus the remaining tail), so a long body's slices agree between the two cards. A source list is prose rather than column-aligned output, so it wraps normally instead of scrolling horizontally the way a terminal card's output does — that is the one deliberate divergence from TerminalBlock.
+
+The card is **resident** under the summary row in the chat rows, capped at `CHAT_WEB_MAX_SOURCES` (8) — half the primitive's own default of 16, which the details panel keeps — the same summary-surface-versus-reading-surface split `CHAT_TERMINAL_MAX_LINES` draws for the terminal card, and the same resident posture `BashRow` uses. The keyed rows register one `WebRow` component under both `web_search` and `web_fetch`; the row discriminates on the tool name only to pick its icon (search vs. browse) and its title (`Search`/`Fetch`). A web-declaring tool without its own keyed row lands on `GenericToolCard`, which grows the same resident card. The details panel renders the card at the primitive's full source allowance and, below it, the flattened model-visible result content: a `web_fetch` card carries only the URL and status, so its fetched body is readable only here.
+
+## Consequences
+
+`WebBlock` reads only the web view's fields, so it stays a pure function of what the render intent carries — no session lookups, replay-safe like the presenters that produce the view, and unlike the terminal card it needs no cwd resolution because a web view carries no path. A UI without the `web` capability (the TUI) still gets the contract's fallback `content`; nothing about the tools' result shape changed. `MarkdownText` is reused for the answer, so the answer's own untrusted-link handling and GFM rendering come for free.
+
+A separate later PR unifies the whole-row collapse/expand interaction and will flip every resident card (terminal, diff, web) to expand-gated at once; this card follows the current resident convention rather than pre-empting that change.
+
+## Alternatives considered
+
+**Two components, one per kind.** Rejected: the two shapes share their card chrome, their safe-link handling, and their truncation indicator, and the contract already expresses their difference as a `kind` discriminant under one `card` tag; two components would duplicate the shared surface and split the safe-link logic.
+
+**Reparse the model-facing render text instead of consuming the structured view.** Rejected for the same reason the contract note gives: `web_search`'s render collapses each source's fields into one free-text line labelled by title OR hostname, so reparsing cannot recover `{url, title?, snippet?, publishedAt?}`. The structured `resultView` is the only faithful source, which is why the backend PR added it.
+
+**Render plain anchors without the protocol allowlist.** Rejected: the URL is model-authored and unverified at this seam, so an unfiltered href would let a `javascript:` URL execute on click. The allowlist is the http(s) subset of MarkdownText's (which also permits `mailto:`), so untrusted retrieval links behave identically wherever they render.
+
+## Testing
+
+`packages/client/ui-primitives/tests/web-block.spec.tsx` pins the component per-file to the 100% gate: both kinds; the title-or-hostname-or-raw-URL label fallback; the safe-link attributes on both kinds (an http(s) URL becoming an external anchor with `target`/`rel`, a `javascript:`/`file:`/unparseable URL rendering as a plain span with no href); the snippet and date shown or omitted on present/empty/absent; the truncation indicator gated on the flag; and the source-list height cap with its head/tail slice and expand/collapse control including the default cap.
+
+`packages/client/ui-conversation/tests/web-card.spec.tsx` mirrors `terminal-card.spec.tsx` at every wiring seam: `webCardModel`'s derivation projecting every source field, its truncation and absent-answer arms, the fetch derivation, and each null arm (running, null result view, generic result view, unknown card tag, unknown web `kind`); the keyed `WebRow`'s resident card for both kinds capped tighter than the panel, its summary-row-alone running and failed arms; the `GenericToolCard` fallback growing the resident card for a web-declaring tool and keeping the plain row for a non-web call; the details panel's Output section for both kinds — including a `web_fetch`'s body flattened below its URL/status card — and its flattened fallback for a non-web result; and the keyed registration under both `web_search` and `web_fetch` with one component. That file sits on the coverage `exclude` list (`ui-conversation/src/*`), so a coverage run measures none of it.
+
+The fixture (`packages/client/connection/src/client/fixture.ts`) adds turns 66 (`web_search`) and 67 (`web_fetch`), authored inline because the client-side fixture cannot import the web tool: turn 66's result view carries an answer and three sources exercising the citation list (a titled source with a snippet and date, a source with no title so its hostname labels the link, and a source with a date but no snippet) with the capped indicator on; turn 67's carries the fetched URL and a 200 status. Both keep a generic pending call view and add the `web` card only at result time, matching the contract's result-only web shape, and are named after the real tools so they hit the keyed `WebRow`. They are ordered before the todo turn (renumbered to 68) for the same reason the terminal turn is: the standing plan retires at the next `turn/start`, so a turn appended after it would empty the dock's plan strip. This drives the built-boot snapshot and a live `?fixture` server.

+# Agent Note: Web result 卡片前端 —— 在浏览器渲染 web 渲染意图
+
+Status: implemented
+
+[English](2026-07-30-web-result-card-frontend.md) | 中文
+
+## Problem
+
+`web_search` 和 `web_fetch` 工具声明了 `card: 'web'` result view（[web result card](2026-07-30-web-result-card.md)）：一个 `kind` 标签联合,携带结构化的被引用 sources 加可选的 provider answer（`kind: 'search'`),或抓取的 URL 及其 HTTP 状态（`kind: 'fetch'`）。该视图早已抵达浏览器 —— host、connection、runtime 将它作为 `resultView` 投递到 `ConversationSnapshot` —— 但 Web 客户端忽略了它:一次已完成的 web 调用只渲染为摊平的模型可见文本,正是契约笔记所解释的、结构化视图要替代的那种有损渲染。`web_search` 到达读者时是每个 source 一行自由文本 markdown,而非可点击 source 的引用列表;`web_fetch` 是它的 markdown 正文,没有检索摘要。
+
+## Decision
+
+`WebBlock` 是一个 `ui-primitives` 组件,渲染一次已完成的 web 检索,web 调用的每个 Web 渲染点都通过它消费 `web` 渲染意图:键控的 chat 工具行（`web_search`/`web_fetch`）、`GenericToolCard` 渲染点兜底,以及详情面板的 Output 区。`ui-conversation/src/client/contract/web-card-model.ts` 是唯一把快照的 `resultView` 转成组件 props 的地方,镜像 `terminal-card-model.ts`,因此没有两个渲染点会对一次 web 调用的显示产生分歧。它返回 null —— 走通用路径 —— 对运行中的调用（web 卡片是 result-only 的,因为工具保留 generic pending 视图）、对 result view 不是 web 卡片的已结算调用（包括本客户端版本不认识的 `card` 值,它经 wire 抵达因而不能被信任为已编译的变体）、对 generic result view（web 工具的错误路径返回 generic 卡片,其文本由通用路径保留）、以及对本客户端版本不认识 `kind` 的 web 卡片（更新的 host 经 wire 发来的值,读作 fetch 会画出空 URL 和 `HTTP undefined`）。
+
+一个组件绘制两种 kind,由 `kind` 判别。`search` 把 answer 作为 markdown 显示在引用列表上方;每个 source 是一个安全外链,以其标题为标签,provider 未给标题时以其主机名为标签,下方是 snippet 与发布日期,工具截断列表时显示 `来源列表已截断` 提示。`fetch` 显示一个紧凑摘要:带链接的最终 URL、其 HTTP 状态、以及 `内容已截断` 提示。用一个组件而非两个,因为两者都是渲染为同一卡片族的 web 检索 —— 这正是契约把它们放在一个 `card` 标签下、用 `kind` 判别的原因。
+
+**链接的安全性沿用 MarkdownText 对不受信任的 assistant 链接所用 allowlist 的 http(s) 子集。** MarkdownText 还允许 `mailto:`，此处刻意排除，因为检索 URL 绝不会是邮件地址。一个 source 或 fetch URL 仅当其协议为 `http:` 或 `https:` 时才成为可导航锚点，带 `target="_blank"` 和 `rel="noopener noreferrer"`；`javascript:`/`data:`/`file:`/`mailto:` URL 或无法解析的字符串渲染为纯文本、无 href。web 工具返回的 result content 是模型创作的,未经验证抵达本组件,因此像 assistant markdown 一样被当作不受信任处理。标签从标题回退到主机名再回退到原始 URL,因此即便标题缺失且 URL 无法解析,source 也总能读作某个东西。
+
+**几何镜像 CodeBlock/TerminalBlock**（12px 圆角、code-block 表面、16px 垂直外边距）,使 web 卡片与它们读作一家。长 source 列表在 `maxSources` 处折叠,用 TerminalBlock 完全相同的分割算术做头/尾折叠（`ceil(max/2)` 头部行加剩余尾部）,使长正文的切片在两张卡之间一致。source 列表是散文而非按列对齐的输出,所以它正常换行,而不像终端卡片的输出那样横向滚动 —— 这是与 TerminalBlock 唯一刻意的分歧。
+
+卡片在 chat 行中**常驻**于摘要行之下,上限 `CHAT_WEB_MAX_SOURCES`（8）—— 原语自身默认 16 的一半,面板保留 16 —— 与 `CHAT_TERMINAL_MAX_LINES` 为终端卡片所画的摘要面对阅读面的同一划分,以及 `BashRow` 所用的同一常驻姿态。键控行把一个 `WebRow` 组件注册在 `web_search` 与 `web_fetch` 两个键下;行仅根据工具名判别以选取其图标（search 对 browse）与标题（`Search`/`Fetch`）。没有自己键控行的 web 声明工具落到 `GenericToolCard`,它长出同一张常驻卡片。详情面板以原语的完整 source 额度渲染卡片,并在其下方渲染摊平的模型可见结果内容:`web_fetch` 卡片只携带 URL 与状态,因此其抓取正文只在此处可读。
+
+## Consequences
+
+`WebBlock` 只读 web view 的字段,因此它是渲染意图所携带内容的纯函数 —— 无会话查找,与产出该视图的 presenter 一样回放安全,且不同于终端卡片它不需要 cwd 解析,因为 web view 不携带路径。没有 `web` 能力的 UI（TUI）仍得到契约的回退 `content`;工具的 result 形状没有任何改变。answer 复用 `MarkdownText`,因此 answer 自身的不受信任链接处理与 GFM 渲染免费获得。
+
+一条独立的后续 PR 会统一整行折叠/展开交互,并把每张常驻卡片（terminal、diff、web）一次性翻成 expand-gated;本卡片遵循当前的常驻约定,而非抢先做那次改动。
+
+## Alternatives considered
+
+**两个组件,每种 kind 一个。** 拒绝:两种形状共享卡片外框、安全链接处理、截断提示,而契约已经把它们的差异表达为一个 `card` 标签下的 `kind` 判别;两个组件会重复共享表面并拆分安全链接逻辑。
+
+**重解析模型可见的渲染文本,而非消费结构化视图。** 因契约笔记给出的同一理由拒绝:`web_search` 的渲染把每个 source 的字段压缩成一行自由文本、以标题或主机名为标签,所以重解析无法恢复 `{url, title?, snippet?, publishedAt?}`。结构化的 `resultView` 是唯一忠实来源,这正是后端 PR 添加它的原因。
+
+**不加协议 allowlist 直接渲染裸锚点。** 拒绝:URL 在此接缝处是模型创作、未经验证的,所以未过滤的 href 会让 `javascript:` URL 在点击时执行。该 allowlist 是 MarkdownText allowlist（它还允许 `mailto:`）的 http(s) 子集,因此不受信任的检索链接无论在何处渲染都行为相同。

+# Agent Note: GUI Full access risk confirmation
+
+Status: implemented
+
+English | [中文](2026-07-31-gui-full-access-confirmation.zh.md)
+
+## Problem
+
+Switching the web client to `danger-full-access` was a single click on either permission surface (the composer's Access chip and the `/permission` popup picker), with the preset shown as the title-cased machine name `Danger Full Access`. Full access reduces confirmation steps and lets the agent run sensitive operations, modify files, or execute external commands, so an accidental pick armed the most dangerous preset with no deliberate acknowledgement step.
+
+## Decision
+
+**Both permission surfaces gate `danger-full-access` behind one shared in-page `RiskConfirmation` dialog whose enabling action stays disabled until an explicit acknowledgement checkbox is checked; the preset renders under the product label `Full access`; every dismissal path submits nothing.**
+
+- `RiskConfirmation` (ui-primitives) is a controlled Modal composition: title, description, acknowledgement checkbox, cancel, and a confirm button disabled until `acknowledged`. It stays an in-page dialog — the Modal portals to this document's body and never opens a native or separate browser window that could land on another display. `Modal` gains a `contentClassName` seat so the warning body scrolls inside constrained mobile/landscape viewports while the action row stays fixed.
+- The composer chip (`PermissionSelect`, ui-conversation) intercepts a Full-access pick before the `/permission` submit: `confirmation`/`acknowledged` component state opens the dialog, confirm submits `/permission danger-full-access` through the same injected `command` path as every other pick, and cancel/Escape/close/mask leave the current preset untouched with the checkbox reset. The confirmation revokes itself when the session locks (`locked`/value-absent effect) and resets across task switches (`key={sessionId}` remount). Copy rides the standard `conversation` locale seat as `access.confirm.*` keys.
+- The `/permission` popup (ui-permission over the ui-command shell) gates through data, not a second dialog implementation: `SelectOption` grows an optional `confirmation` payload, the popup controller owns the `confirming`/`acknowledged` state transitions, and `PopupSelectView` swaps the picker card for the same `RiskConfirmation` while a gated option is pending.
+- `Full access` intentionally overrides the kebab-to-title display transform on both surfaces (option rows, trigger label, settled command rows keep the machine name on the wire); the warning body remains locale-aware in Chinese and English.
+
+## Alternatives considered
+
+**A native/OS or separate-window confirmation.** Rejected: the dialog must stay inside the current WebUI window; a second window can appear on another display and detaches the decision from the page state it guards.
+
+**One shared locale namespace for both surfaces' safety copy.** Rejected: the ui-permission bundle and ui-conversation load independently, so each registers the same copy under its own namespace (`permission.access` beside the conversation dictionary); the duplication is fenced with an explanatory `jscpd:ignore` block rather than a cross-bundle import.
+
+**Gating in the host/permission backend.** Out of scope by design: the change is browser-client confirmation flow only; backend permission semantics, defaults, and the safer presets' one-click behavior are unchanged.
+
+## Consequences
+
+Every visible GUI path into Full access now requires a deliberate, informed acknowledgement, at the cost of one extra dialog step for users who genuinely want the preset. New pickers reuse the gate by attaching a `confirmation` payload (popup path) or the chip's state machine (composer path) instead of inventing bespoke dialogs. Acceptance: the composer flow's four gated cases in `input-bar.spec.tsx`, the popup gate in `popup-view.spec.tsx` and `popup.spec.ts`, the Modal/RiskConfirmation contract in `atoms.spec.tsx`, and the assembled `access-confirmation` web e2e whose golden pins the product-default Chinese dictionary copy.

+# Agent Note: GUI Full access 风险确认
+
+Status: implemented
+
+[English](2026-07-31-gui-full-access-confirmation.md) | 中文
+
+## Problem
+
+Web 客户端切换到 `danger-full-access` 在两个权限面（编辑器的 Access chip 与 `/permission` popup 选择器）上都只需一次点击，且预设以 Title Case 机器名 `Danger Full Access` 展示。Full access 会减少确认步骤，允许智能体执行敏感操作、修改文件或运行外部命令，误点即在毫无刻意确认环节的情况下启用了最危险的预设。
+
+## Decision
+
+**两个权限面都把 `danger-full-access` 关进同一个共享的页面内 `RiskConfirmation` 对话框：启用按钮在用户勾选明确的风险确认复选框前保持禁用；预设以产品标签 `Full access` 展示；所有取消路径都不提交任何命令。**
+
+- `RiskConfirmation`（ui-primitives）是受控的 Modal 组合：标题、说明、确认复选框、取消，以及 `acknowledged` 勾选前禁用的确认按钮。它始终是页面内对话框——Modal portal 到本文档 body，绝不打开可能落在另一块显示器上的原生或独立浏览器窗口。`Modal` 新增 `contentClassName` 座位，令警示正文在受限的移动端／横屏视口内滚动，动作行保持固定。
+- 编辑器 chip（ui-conversation 的 `PermissionSelect`）在 `/permission` 提交前拦截 Full-access 选择：`confirmation`/`acknowledged` 组件状态打开对话框，确认后经与其他选择完全相同的注入 `command` 通道提交 `/permission danger-full-access`；取消、Escape、关闭与遮罩点击均保持当前预设不变并重置复选框。会话锁定时确认自行撤销（`locked`／值缺席 effect），切换任务时随 `key={sessionId}` 重挂载而重置。文案经标准 `conversation` locale 座位以 `access.confirm.*` 键供给。
+- `/permission` popup（ui-permission 骑在 ui-command 外壳上）以数据而非第二套对话框实现完成把关：`SelectOption` 新增可选的 `confirmation` 载荷，popup 控制器拥有 `confirming`/`acknowledged` 状态迁移，`PopupSelectView` 在门控选项未决期间把选择卡换成同一个 `RiskConfirmation`。
+- `Full access` 在两个面上有意覆盖 kebab 转 Title Case 的显示变换（选项行、触发器标签；落定的命令行仍在 wire 上保留机器名）；警示正文保持中英文 locale 感知。
+
+## Alternatives considered
+
+**原生／操作系统或独立窗口确认。** 已拒：对话框必须留在当前 WebUI 窗口内；第二个窗口可能出现在另一块显示器上，使决策脱离其守护的页面状态。
+
+**两个面共享一个安全文案 locale namespace。** 已拒：ui-permission bundle 与 ui-conversation 可独立加载，故各自在自己的 namespace 下注册同一份文案（`permission.access` 与 conversation 词典并立）；这处重复以带说明的 `jscpd:ignore` 块圈护，而非跨 bundle import。
+
+**在 host／权限后端把关。** 设计上即出界：本变更只涉浏览器客户端确认流；后端权限语义、默认值与更安全预设的一键行为均不变。
+
+## Consequences
+
+进入 Full access 的每条可见 GUI 路径现在都要求刻意且知情的确认，代价是真想启用该预设的用户多一步对话框。新的选择器复用此门：popup 路径挂 `confirmation` 载荷、编辑器路径走 chip 的状态机，而不是各造对话框。验收：`input-bar.spec.tsx` 中编辑器流的四个门控用例、`popup-view.spec.tsx` 与 `popup.spec.ts` 的 popup 门、`atoms.spec.tsx` 的 Modal/RiskConfirmation 契约，以及组装态 `access-confirmation` web e2e——其 golden 钉住产品默认中文词典文案。

+# Agent Note: Product-first root README
+
+Status: implemented
+
+English | [中文](2026-07-22-product-first-root-readme.zh.md)
+
+## Problem
+
+The root README is the repository's product front door. Its product-first structure and established voice remain useful, but concrete entry points and capability claims drift as the runtime grows. Rewriting sections whose facts remain correct increases the review surface and discards language that already works.
+
+## Decision
+
+The root README preserves its existing structure, order, and wording wherever the underlying fact remains correct. A refresh changes only stale claims and adds material needed to represent shipped surfaces; it does not use repository growth as a reason to reframe the whole page.
+
+A note before installation thanks internal testers, states that features and experience remain unfinished, and asks for direct reports of failures, confusion, and friction through the WeCom group. The existing development-stage statement identifies DeepSeek Harness as being in internal testing.
+
+The user-surface section adds the ACP automation server and Python/JSON-RPC SDK beside the existing Web, TUI, and headless entries. The installed TUI remains the single `dsh` command; the Web instructions build the active checkout before running `dsh web`, and custom or reused checkout paths stay explicit. These launch paths must remain executable through a real PTY and a production build/HTTP smoke, respectively. The capability paragraph keeps its compact inventory style while adding the shipped PTY, LSP, web, goal, planning, task, sandbox, approval, settings, credentials, session-query, and telemetry families and stating that compositions select subsets. One adjacent bullet records the authoritative-session-log rule because persistence, replay, queries, telemetry, and interfaces depend on it.
+
+Detailed package and service inventories remain at their owning documentation. The English and Chinese README sides share the same technical structure, while their community sections continue to point to the primary channel for each language audience. The documentation website keeps its separate user-guide landing page.
+
+## Alternatives considered
+
+**Rewrite the README around a new product narrative.** A complete rewrite can make every current surface prominent, but it replaces accurate, reviewed copy and creates unnecessary churn. Current facts fit the established product-first structure.
+
+**Present the repository as an SDK and package catalog.** This exposes implementation breadth immediately but makes a new reader reconstruct the product from package names. The package map and generated capability graph remain the authoritative inventories.
+
+**Use a long marketing page with screenshots, badges, and duplicated tutorials.** Rich media can demonstrate a stable product journey, but it ages separately from commands and source contracts. The root stays compact and links to runnable examples and owned guides.
+
+**Project the root README as the documentation website home page.** A single landing page avoids two narratives, but the website's user guide and the repository's product/developer front door have different navigation and maintenance needs.
+
+## Consequences
+
+Reviewers can distinguish factual refreshes from editorial rewrites, and future updates retain established wording unless its meaning becomes false or incomplete. The README must still change with affected commands, entry points, release-stage claims, or high-level capability families, while exhaustive detail remains linked rather than copied.

+# Agent Note: 产品优先的根 README
+
+Status: implemented
+
+[English](2026-07-22-product-first-root-readme.md) | 中文
+
+## 问题
+
+根 README 是仓库的产品入口。其产品优先的结构和既有语气仍然有效，但随着运行时不断扩展，具体入口和能力声明会逐渐陈旧。重写事实仍然正确的章节，会扩大评审范围，也会丢弃已经行之有效的措辞。
+
+## 决策
+
+只要背后的事实仍然正确，根 README 就保留既有结构、顺序和措辞。刷新时只修正陈旧声明，并补充呈现已交付内容所需的信息；不会因为仓库规模增长就重构整篇叙事。
+
+安装说明之前的一则文字感谢内测用户，说明功能和体验仍待完善，并邀请大家通过企业微信群直接反馈失败、困惑和不顺手之处。既有的开发阶段声明明确说明 DeepSeek Harness 处于内测阶段。
+
+用户入口章节在已有的 Web、TUI 和 Headless 入口旁补充 ACP（Agent Client Protocol）自动化服务器和 Python/JSON-RPC SDK。安装后的 TUI 仍只需执行一条 `dsh` 命令；Web 说明要求先构建当前检出，再运行 `dsh web`，并明确处理自定义或复用的检出路径。这两条启动路径必须分别能在真实 PTY 与生产构建／HTTP 冒烟中原样执行。能力段落沿用简洁清单的写法，补充已经交付的 PTY、LSP、Web、目标、规划、任务、沙箱、审批、设置、凭据、会话查询和遥测等能力类别，并说明不同组合只选用其中一部分。相邻的一条列表项说明权威会话日志规则，因为持久化、回放、查询、遥测和各类接口都依赖它。
+
+包（package）与服务的完整清单仍由各自的归属文档维护。中英文 README 采用相同的技术结构，但社区章节仍分别指向各自语言受众的主要交流渠道。文档网站继续使用独立的用户指南首页。
+
+## 考虑过的替代方案
+
+**围绕新的产品叙事重写 README。** 完整重写能够突出所有现有入口和能力，但也会替换准确且已经过评审的文案，造成不必要的变动。现有事实能够纳入既有的产品优先结构。
+
+**将仓库呈现为 SDK 和包清单。** 这样能立即展现实现广度，却会迫使新读者从包名反推出产品。包索引与生成的能力图仍是权威清单。
+
+**使用包含截图、徽章和重复教程的长篇营销页面。** 富媒体能够展示稳定的产品使用路径，但其内容会独立于命令和源码契约而逐渐陈旧。根 README 保持紧凑，并链接到可运行示例和各自维护的指南。
+
+**将根 README 投影为文档网站首页。** 使用同一个首页可以避免两套叙事，但文档网站的用户指南与仓库面向产品和开发者的入口在导航和维护需求上并不相同。
+
+## 结果
+
+评审者可以区分事实更新与编辑性重写；今后的更新会保留既有措辞，除非其含义已经不再正确或完整。受影响的命令、入口、发布阶段声明或高层能力类别发生变化时，README 仍须同步更新；完整细节则继续以链接方式提供，而不是复制到正文。

@@ -17,8 +17,7 @@ The TUI surface:
 
 `dsh upgrade` is a guided fresh-session entry over the default TUI surface: it mints a fresh session in the invoking directory and seeds its first turn with the bundled `dsh-upgrade` skill, exactly as if the user typed `/skill:<name>`. The launcher passes the skill name on the boot context ([`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)), which the TUI auto-invokes once the chat is live. Both take no options — `--config`, `-p`, and `--resume` fail loud — and seed only on this first launch, so a later `dsh --resume <id>` of the session is an ordinary TUI session with no re-injection.

-The Web and headless surfaces boot `base.cordis.yml` plus `web.cordis.yml`, then apply `$DSH_HOME/config.yaml`; an explicit `--config <path>` replaces that personal overlay. Both surfaces otherwise share the same composition: both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root <path>` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, opt into first-message model titles, and mount a disposable in-memory SQLite content-index service. That service is ACTIVE at boot, while its `node:sqlite` module and database handle open only on the first content search. This keeps Node 22 startup output free of SQLite's experimental warning before search is used; the first actual search may still emit the runtime warning. Each service instance owns its database, so parallel invocations neither share unsupported SQLite state nor leave derived index files behind, and the first search lazily reconciles live and persisted logs. Headless differs only in listening on an OS-assigned port (parallel `dsh -p` runs never collide; the stderr-printed URL opens the live session in a browser). Both need the frontend dist and client bundles built (`pnpm run build && pnpm run build:web`).

 `dsh upgrade` 是默认 TUI 界面之上的引导式全新会话入口：它在调用目录中创建一个全新会话，并以内置 `dsh-upgrade` skill 播种其首轮，效果等同于用户手动键入 `/skill:<name>`。启动器将 skill 名称提供到启动上下文（[`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)），TUI 在聊天就绪后自动调用它。两者都不接受任何选项——`--config`、`-p`、`--resume` 都会明确报错——且仅在首次启动时播种，因此之后 `dsh --resume <id>` 恢复该会话时是普通 TUI 会话，不会重复注入。

 `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. `ISession.rename` settles the `title` projection cell directly from the unary response's `{title, seq}` under the same higher-seq-wins rule — the list row and every `useProjection('title')` reader update ahead of the push frame, whose later replay of the same seq is a no-op.
 
+## Model retry projection
+
+The Session object validates plugin-owned, provider-routed `llm/retry` payloads at the event wire boundary against the producer's complete field contract, including timer, integer, status, provider-delay, and non-empty diagnostic bounds. A valid event removes the matching failed step's streaming partial and inserts a durable retry notice at the event's sequence position. The notice is `scheduled` until a following retry turn starts; an aborted or disposed source turn marks it `cancelled`, while the retry turn marks it `started`. Normal-mode notices carry their finite maximum; always-mode notices remain explicitly unbounded. Window rebuild and history replay apply the same projection, so logged chunks from the discarded attempt never reappear as an interrupted reply after refresh. A terminal turn without `llm/retry` retains the existing behavior: visible unfinalized output is frozen as an interrupted assistant node.
+
 ## Session forking
 
 `ISessions.fork({sessionId, atSeq?, increaseTitle?})` resolves only after the child summary is locally addressable, carrying source lineage and cwd with `blank: false`; callers choose whether to open it. With `increaseTitle: true`, the client renames the child from the source session's persisted title: a trailing `(N)` or `（N）` is incremented without changing bracket style, while any other title gets ` (1)` appended; the rename is skipped when the source has no persisted title, and a rename failure rejects the promise but leaves the created child in place. This option is not sent in the Host fork request. A `workspace-attach-failed` response still identifies a child already published by the Host, so `SessionManager` reconciles that partial success before `SessionForkError` reaches the caller instead of making a retry create a duplicate child.

 `SessionManager` 独立于列表和 Session 实例到达情况，保留最近一次通过验证的 `session/title` 控制快照。seq 更高的事件会替换旧快照，标题时间戳计入列表新近程度；订阅基线会先丢弃 seq 超过其 `lastSeq` 的任何已保留标题，再接收可选的折叠标题。显式移除 Session 也会清除已保留标题。因此，面向客户端的 `SessionSummary.title` 只包含实际的持久化标题；`displayTitle` 始终存在，并依次回退到 cwd basename 和 Session id。冷态持久化会话会保持该回退值，直到打开或恢复会话，促使主机折叠并投影由日志支撑的标题。`ISession.rename` 用 unary 响应中的 `{title, seq}` 直接结算 `title` 投影格，遵循同一 seq 高者胜规则——列表行和所有 `useProjection('title')` 读者在推送帧到达前即更新；推送帧随后重放同一 seq 时为无操作。
 
+## 模型重试投影
+
+Session 对象会在事件 wire 边界依据生产方的完整字段契约，验证由插件负责、按提供方路由的 `llm/retry` 载荷，包括计时器、整数、状态、提供方延迟和非空诊断字段的边界。有效事件会移除对应失败步骤的流式输出片段，并在该事件的序列位置插入一条持久的重试提示。该提示在后续重试轮次开始前为 `scheduled`；源轮次中止或释放会将其标记为 `cancelled`，重试轮次则会将其标记为 `started`。normal mode 提示携带其有限上限；always mode 提示则保持显式无界。窗口重建与历史回放应用相同的投影，因此刷新后，来自已丢弃尝试的日志分片绝不会重新显示为中断回复。没有 `llm/retry` 的终止轮次保留现有行为：可见但尚未定稿的输出会冻结为中断的 assistant 节点。

 ## 会话 fork
 
 `ISessions.fork({sessionId, atSeq?, increaseTitle?})` 只在子会话摘要已能在本地寻址后才完成；该摘要携带源会话的谱系和 cwd，且 `blank: false`，由调用方决定是否打开。`increaseTitle: true` 会在 client 端把源会话的持久化标题改名到子会话：尾部 `(N)` 或 `（N）` 递增并保留括号样式，其余标题追加 ` (1)`；源会话没有持久化标题时跳过改名，改名失败时拒绝 promise 但保留已创建的子会话。该选项不会进入 Host fork 请求。即使响应为 `workspace-attach-failed`，其中仍会标识 Host 已发布的子会话，因此 `SessionManager` 会先将这一部分成功对账，再让 `SessionForkError` 到达调用方，避免重试创建重复的子会话。

@@ -8,13 +8,19 @@ The resident conversation shell survives no-session and session transitions. Wit
 
 The view ring IS a slot: the conversation registration declares the `'conversation.view'` list slot (session scope) in its `children` table, ConversationRoot renders the active entry through its renderSlot share (`only: <active id>`), and view tabs project from the ring ledger's registration options (`id`/`order`/`label`). The chat view is this package's own ring entry; other plugins (ui-trajectory) contribute tabs through plain `ctx.slots.register` — the former package-local view registry (`registerView`/`ViewEntry`/`ConversationViewMap` and the chrome attachment table) is retired, with per-view chrome dissolved into the view components themselves.
 
-Approvals take over the composer through the chain this package declares: `ApprovalPanel` registers as a selector-routed `'conversation.composer'` entry (the ui-question pattern) and occupies the composer in place of the InputBar while an approval wait is pending (amber strip, justification headline, paired command line from the running call's args, one-shot refuse/allow). The `PendingApproval` domain face in `contract/slots.ts` owns the wire encoding — the `ApprovalResponsePayload` value with the audit correlation — over the runtime's `PendingWait` carrier; the broadcast `approval/resolved` frame settles the wait and restores the composer. The sidebar mirrors the blocked state through the manager-tracked `waitingApproval` list bit (lit for uninstantiated sessions too), which outranks the running ring until the question resolves. Pending waits leave the message flow entirely: questions (ui-question) and approvals (ApprovalPanel) both answer through the composer takeover, so no display-only placeholder card remains. The composer's bottom-row Access seat mounts `PermissionSelect`, fed by the host-computed `permissions` projection through the standard-kit `useProjection` (key absence hides the chip); the chip opens a Menu-primitive dropdown whose kebab-case preset names render as title-case labels (the `/permission` popup's display transform twin), and a pick submits the `/permission <preset>` command line through the bar's injected `command` callback.

Safe preset picks submit `/permission <preset>` immediately through the bar's injected `command` callback, while `danger-full-access` is presented as `Full access` and first opens an in-page Modal risk confirmation. The enabling action stays disabled until the user checks the acknowledgement; cancel, Escape, close, and mask click submit nothing.
 
 Logged non-user messages render as a default-collapsed `上下文注入` disclosure. It shares the Tool calls header geometry and interaction with `ToolRow` through the package-internal `DisclosureRow`, while retaining context semantics: the expanded 141px scrollport shows bounded inline JSON for both `content` and `source`, and no tool state, summary, or keyed toolview dispatch is synthesized ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-context-injection-disclosure.md)).
 
 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 a path summary; that path is a hover-underline link that opens the file with the host OS default application (`host.openPath`, relative paths resolve against the session cwd). Tool rows are not whole-row click targets and do not open the details panel. 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). Cordis lifecycle tools reuse those generic variants while presenting `Inspect`, `Mount temporary Plugin`, and `Unmount temporary Plugin` with a shared Cordis accent; mount keeps the code variant's expandable source rendering.
 
-A tool call declaring the `terminal` render intent renders its command output inline, at both conversation render sites, through ui-primitives' `TerminalBlock`. `contract/terminal-card-model.ts` is the single derivation from the snapshot's `callView`/`resultView` pair, so the sites cannot disagree about a command, its cwd, or its exit status; it yields null — the generic path — for any other card tag, including one this client version does not know. Both sites therefore also show the card's run-state dot, which is the same `StateDot` semantic a tool row's leading icon carries, so a row and its own card always agree about one command's state. A multi-line command gets one prompt row per line, with the dot marking the call once on the first row — the exit status is the whole call's, so a dot per line would claim a per-line outcome bash does not report. The keyed `BashRow` carries the card resident below its summary row; since tool rows are no longer details-panel click targets, the card's copy and expand controls are the row's only interactions. The render-site fallback row keeps the card behind its existing expand control. Rows cap at `CHAT_TERMINAL_MAX_LINES` (8) against the panel's 16, which is what keeps a summary surface bounded — the panel stays the single-call reading surface. Inline output is licensed for this intent alone; a generic tool's content remains panel-only ([decision](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md)).

Inline output is licensed per render intent — the terminal and web cards, each with its own bound; a generic tool's content remains panel-only ([decision](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md)).
+
+A tool call declaring the `web` render intent renders its web retrieval inline, at both conversation render sites, through ui-primitives' `WebBlock`. `contract/web-card-model.ts` is the single derivation from the snapshot's `resultView`, mirroring the terminal card, so the sites cannot disagree about what a web call shows; it yields null — the generic path — for a running call, a non-web result view, a generic result view, a `card` tag this client version does not know, or a web card whose `kind` this client version does not know (a newer host's value, which the wire cannot be trusted to be `search` or `fetch`). The keyed `WebRow` registers one component under both `web_search` and `web_fetch`, discriminating on the tool name only for its icon and title; a web-declaring tool without a keyed row lands on the `GenericToolCard` fallback, which grows the same resident card, and the details panel renders it at the primitive's full source allowance and, below the card, the flattened model-visible result content — a fetch body is readable only there, since its card carries only the URL and status. Rows cap at `CHAT_WEB_MAX_SOURCES` (8) against the panel's 16, the same summary-versus-reading split the terminal card draws ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card-frontend.md)).
+
+A tool call declaring the `diff` render intent (the `write`/`edit` tools) renders its applied change inline through ui-primitives' `DiffBlock`, the same four-layer shape. `contract/diff-card-model.ts` is the single derivation from the `callView`/`resultView` pair; the settled result's hunks replace the call-time diff, and it yields null — the generic path — for any other card tag or a generic result view (write/edit's execution errors). The keyed `FileMutationRow` (registered under both `write` and `edit`) carries the card resident below its summary, whose path link still opens the file through the host; the render-site fallback and the details panel are diff-aware too. Rows cap at `CHAT_DIFF_MAX_LINES` (8) against the panel's 16 ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-diff-card.md)).
+
+The chat flow projects consecutive model-retry nodes across retry turns into one stable, muted status row updated to the latest attempt; every retry event remains in the runtime snapshot and session log. Its frontend countdown anchors the scheduled delay to client receipt, avoiding host/browser clock skew, rounds remaining time up to seconds, and has a one-second floor. The latest unresolved retry uses a left-to-right text shimmer. Subsequent turn facts distinguish an attempt that started from one cancelled during backoff, while the Host running bit only controls the live animation; the row then shows a static completed or cancelled label. Normal policy rows show the finite retry maximum; always policy rows show `∞`. Activating the row reveals the latest exact retry delay and failure message. The client runtime removes each failed step's streaming tail before its retry node arrives, while the status remains visible after a later attempt succeeds.
 
 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`/`openFile`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '<tool>', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar). Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders).

 通用工具行把内置的 bash、read、search、write、edit 和 run_code 名称归入专用视觉变体。文件系统变体会渲染 edit 图标和路径摘要；该路径是悬停下划线链接，点击后通过宿主操作系统的默认应用打开文件（`host.openPath`，相对路径相对会话 cwd 解析）。工具行不再是整行点击目标，也不会打开 details 面板。code 变体以模型撰写的 `description` 作摘要，展开后显示程序本身；其已记录的子调用经由同一个键控 toolview 空位渲染为始终可见的嵌套行（自定义注册和 GenericToolCard fallback 原样适用于子行）。Cordis 生命周期工具复用这些通用变体，同时以统一的 Cordis 强调色呈现 `Inspect`、`Mount temporary Plugin` 和 `Unmount temporary Plugin`；mount 行保留 code 变体的可展开源码渲染。
 
-声明 `terminal` 渲染意图的工具调用，会在两个对话渲染点上都通过 ui-primitives 的 `TerminalBlock` 内联渲染其命令输出。`contract/terminal-card-model.ts` 是从快照的 `callView`／`resultView` 对推导的唯一位置，因此两个渲染点不可能在命令、cwd 或退出状态上产生分歧；对任何其他 card 标签——包括当前客户端版本不认识的标签——它返回 null，落回通用路径。因此两个渲染点也都显示卡片的运行状态点，它与工具行行首图标承载同一套 `StateDot` 语义，所以一行与其自身的卡片对同一条命令的状态总是一致。多行命令的每一行各占一个提示行，状态点只在第一行为整次调用标记一次——退出状态属于整次调用，因此每行一枚就会声称一个 bash 并不报告的逐行结果。键控的 `BashRow` 把卡片常驻在摘要行下方；由于工具行已不再是详情面板的点击目标，卡片的复制与展开控件就是该行唯一的交互。渲染点兜底行则保持其既有的展开控件。行的上限是 `CHAT_TERMINAL_MAX_LINES`（8），面板为 16，正是这一点让摘要面保持有界——面板仍是单次调用的阅读面。内联输出只对该意图开放；通用工具的内容仍然只在面板中呈现（[决策](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md)）。

+聊天流会将跨重试轮次连续出现的模型重试节点投影为一个稳定的弱化状态行，并用最新一次尝试更新该行；每个重试事件仍保留在运行时快照与会话日志中。前端倒计时以客户端收到事件的时刻为计划延迟的起点，避免 Host 与浏览器的时钟偏差；剩余时间向上取整到秒，且下限为 1 秒。最近一次尚未完成的重试会显示从左到右的文字渐变动画。后续轮次事实用于区分已开始的尝试与在退避期间取消的尝试，Host 的 running 位只控制实时动画；随后该行会显示静态的已完成或已取消标签。normal 策略行显示有限重试上限；always 策略行显示 `∞`。激活该行会显示最近一次重试的精确延迟和失败消息。客户端运行时会在相应重试节点到达前移除每个失败步骤的流式输出尾部；后续某次尝试成功后，该状态仍保持可见。
 
 工具行同样是 slot：独立工具环（`ToolViewRegistry`／`ctx.toolviews`／outlet）已经退役。聊天配置项声明键控的 `'conversation.chat.toolview'` 空位（Session scope；key 空间在运行时开放）；其渲染点逐行通过 `entryKey: toolName` 分发，并以 `GenericToolCard` 作为调用点 `fallback`。owner 载荷是统一的 `ToolRowOwnerProps`（`callId`／`toolName`／`block`／`openFile`），`ToolRowProps` 则预先将其与 Session 标准工具包组合。注册方只是普通插件：`ctx.slots.register({ name: 'conversation.chat.toolview', key: '<tool>', inject? }, Row)`，以 `inject: ['slots', 'conversation']` 作为加载顺序 seam（apply 在聊天注册后挂载 ConversationService，因此服务存在即可保证 slot 已声明）；Session 区分在组件内部完成（`useSessions` 读取 `parentId`，bash 示例是第三方姿态的范例）。Trajectory/waterfall 工具视图 slot 共享此形状，并随各自的渲染点落地（RendersCheck 会拒绝没有任何渲染方的声明）。

 todo 两个面就是在该形状上的两个注册项，都是普通注册方插件，`inject: ['slots', 'conversation']`。`TodoRow` 占用 `'conversation.chat.toolview'` 的 `todo_write` key，摘要该次调用「试图写入」的内容（从其 args 解析出 `<已完成>/<总数> 已完成 · <进行中条目>`；模型 JSON 残缺或形状不对时回落到通用摘要；非 ok 执行状态保留通用状态点，使被取消的调用绝不读成一次已完成的更新）。`TodoDock` 以 `order: -1` 占用 `'conversation.input.dock'` 列表 slot（位于队列行之上），是计划条：它经 `useProjection` 读取 host 计算的 `todos` 投影（站立计划：其后没有更晚 `turn/start` 的最近一次 `todo/write`）并渲染 `TodoPanel`，后者接收纯列表，在列表为空时自我隐藏；列表非空时面板初始折叠，表头显示标题加 `"<已完成>/<总数> tasks · <n> in progress"`（状态图标为 figma 的勾选／进行中／虚线未开始一组）。选取由 dock 适配器负责，因此面板保持为其 props 的纯函数；站立列表放在此处而非行内，行才能保持单行。输入区 composer 链隐藏的一切（例如 ui-question 对 `conversation.composer` 的接管）也会隐藏整个 dock，包括这条计划条。
