Its frontend countdown derives from the scheduled delay, rounds remaining time up to seconds, and has a one-second floor. The latest unresolved retry uses a left-to-right text shimmer, then settles to a static completed label. 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`/`openDetails`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar). Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders). Per-session UI state (selection, ordinary composer draft, active view) lives in the declared chat store (`stores.ts` `createChatStore`): apply constructs one handle and passes it to the conversation, chat-view, and details registrations, so the session slots share one instance per session (selection written by the chat view, read by details) and the framework owns instance lifecycle and draft persistence. The frontend Session Intent comes from the Session list projection; after publication, any retained prompt comes from that Session's conversation snapshot. Components are pure — the framework standard kit (`useSession`/`sessionId` when session-scoped, plus global `useSessions`/`useWorkspaces`) and the store faces (`useStore`/`actions`) arrive automatically from the registration declaration;

Compaction can replace visible content without preserving historical usage, and route changes leave the browser without an authoritative context capacity. Cache-write tokens also risk being folded into a cache-hit formula whose denominator has different semantics. + +## Decision + +The Host owns one session-level metrics projection. It incrementally folds the complete durable event log, keys settled usage by `(turn, step)`, and replaces an earlier usage record for the same key instead of double-counting chunk and message forms. Uncached input, output, cache reads, and cache writes remain four disjoint cumulative buckets. Compaction can change the current prompt surface without erasing historical usage. + +Current context pressure is a separate point-in-time value from `tokenMeter.measure(session).totalTokens`. Capacity comes only from `llm.resolveModelInfo(provider, model).context.contextWindow` for the agent's selected route. A route change immediately publishes metrics with capacity absent, then publishes the resolved capacity behind a route generation fence; stale metadata cannot label the new route. + +The tail `session.history` response carries the projection, while older pages omit it. Live changes use `session/metrics` mux frames. Both forms carry a durable-log revision and a projection revision; the client accepts only nondecreasing revisions, preserves metrics across older-page prepend, and clears them at a new subscription baseline. Missing measurement or metadata stays absent. + +The Web stats line treats the projection as its sole token source. It renders uncached input, output, and cache reads separately, computes cache hit as `cacheRead / (uncachedInput + cacheRead)`, and shows current context as a percentage of the exact route capacity. Cache writes never enter that percentage. Visible nodes continue to supply only turn and step counts. + +## Alternatives considered + +**Fold the loaded node window in React.** This cannot survive pagination or compaction and duplicates durable-log semantics in a presentation package. + +**Send usage only with raw assistant events.** Reconnect and older-page stitching would still need the client to reconstruct a full-log aggregate, and duplicate usage forms would need protocol-specific repair there. + +**Reuse one total-token field for cache hit.** Cache reads, cache writes, and uncached input represent distinct provider accounting buckets; combining them would make the displayed rate misleading. + +**Keep the previous capacity until the new route resolves.** The old number would temporarily claim the wrong selected model. An explicit unknown state is honest and generation-safe. + +## Consequences + +Token totals remain stable across pagination, replay, compaction, and browser reconnect. The client stores a small detached projection instead of scanning the conversation window, and the status row remains readable for large histories through compact number formatting. + +The Host performs one incremental log fold per session and schedules live projection updates only for usage, request-header, or surface-changing events; text and reasoning deltas do not publish metrics. Exact capacity resolution is asynchronous and may briefly render as unknown. Deployments without a token meter or model context metadata retain the row and label the unavailable value instead of fabricating one. diff --git a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md b/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md new file mode 100644 index 0000000000..6ad06ea615 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md @@ -0,0 +1,35 @@ +# Agent Note: Host 拥有的 Web 会话指标 + +Status: implemented + +[English](2026-07-28-host-owned-web-session-metrics.md) | 中文 + +## 问题 + +Web 统计行若根据当前加载的会话节点推导指标，其结果会随分页窗口变化。压缩（compaction）可以替换可见内容，却无法保留历史用量；路由变更会让浏览器缺少权威的上下文容量。缓存写入 token 还可能被计入缓存命中率公式，而该公式的分母具有不同语义。 + +## 决策 + +Host 拥有一项会话级指标投影。它以增量方式归并完整的持久事件日志，按 `(turn, step)` 标识已结算用量；同一标识再次出现时，会替换较早的用量记录，而不会重复统计分片和消息两种形态。未缓存输入、输出、缓存读取与缓存写入保持为四个彼此独立的累计计数项。压缩可以改变当前提示词表层，但不会抹除历史用量。 + +当前上下文压力是一个独立的即时值，取自 `tokenMeter.measure(session).totalTokens`。容量仅来自 `llm.resolveModelInfo(provider, model).context.contextWindow`，并对应 agent（智能体）所选的路由。路由变更时，Host 会立即发布不带容量的指标，再通过路由代际围栏发布解析出的容量；陈旧元数据无法标记新的路由。 + +`session.history` 尾页响应携带该投影，较早页面则省略它。实时变更使用 `session/metrics` mux 帧。两种形式都携带持久日志修订号和投影修订号；客户端只接受不减小的修订号，在向前加载较早页面时保留指标，并在建立新的订阅基线时将其清除。测量值或元数据缺失时，对应字段保持缺失。 + +Web 统计行把该投影视为唯一的 token 数据来源。它分别呈现未缓存输入、输出与缓存读取，通过 `cacheRead / (uncachedInput + cacheRead)` 计算缓存命中率，并把当前上下文显示为精确路由容量的百分比。缓存写入绝不计入缓存命中率。可见节点仍然只提供轮次和步骤计数。 + +## 备选方案 + +**在 React 中归并已加载的节点窗口。** 此方案无法跨越分页或压缩保留数据，还会在展示包中重复实现持久日志语义。 + +**只随原始 assistant 事件发送用量。** 重连和较早页面拼接仍会要求客户端重建完整日志聚合，而且重复的用量形态需要在客户端按协议专门修复。 + +**为缓存命中率复用单一的 token 总数字段。** 缓存读取、缓存写入与未缓存输入是提供方记账中的不同计数项；将它们合并会使显示的比率产生误导。 + +**在新路由解析完成前保留旧容量。** 旧数值会在短时间内错误标示所选模型。显式的「未知」状态能如实反映情况，并避免跨代串扰。 + +## 后果 + +token 总量在分页、回放、压缩和浏览器重连期间保持稳定。客户端存储一项小型脱耦投影，无需扫描会话窗口；状态行采用紧凑数字格式，因此在较长的历史记录中仍然清晰易读。 + +Host 为每个会话执行一次增量日志归并，仅为用量事件、请求头事件或表层变更事件调度实时投影更新；文本与推理（reasoning）增量不会发布指标。精确容量解析为异步操作，因此可能短暂显示「未知」。未部署 token 计量器或缺少模型上下文元数据时，系统仍保留该行，并标示不可用的值，而不会虚构数据。 diff --git a/apps/web/tests/snapshots/fresh-round-trip/ui.expected.md b/apps/web/tests/snapshots/fresh-round-trip/ui.expected.md index dc572023fd..29d039fd53 100644 --- a/apps/web/tests/snapshots/fresh-round-trip/ui.expected.md +++ b/apps/web/tests/snapshots/fresh-round-trip/ui.expected.md @@ -7,22 +7,30 @@ - tab "Trajectory" - tab "Waterfall" - text: "Use the bash tool to run exactly: echo WEB_E2E_OK.

Older pages omit the session-level projections. Live `session/metrics` mux frames carry monotonic log/projection revisions, so clients reject stale frames and preserve the counters while prepending older pages. Cache reads and writes remain disjoint buckets; the cache-hit denominator is uncached input plus cache reads. The `command.*` and `skill.*` domains expose the host command registry and skill catalog to clients. Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `command.execute` runs a slash-command line host-side and returns a detached result; the carrier's request signal cancels the running handler. `host/commands-changed` is the catalog invalidation frame: clients refetch `command.list` instead of diffing. diff --git a/packages/host/apiproxy/README.zh.md b/packages/host/apiproxy/README.zh.md index 4175c8fdb9..cfdf0d772a 100644 --- a/packages/host/apiproxy/README.zh.md +++ b/packages/host/apiproxy/README.zh.md @@ -18,7 +18,7 @@ Workspace 列表与 Session 列表是相互独立的重连基线。`workspace.cr `host.pickDirectory` 会打开一个原生目录选择器并返回选中的路径；用户取消时返回 `null`。宿主实现不经 shell 调用平台工具：macOS 使用 `osascript`，Windows 使用以 STA 模式运行的 PowerShell `FolderBrowserDialog`，Linux 使用 Zenity，并以 KDialog 作为回退。选择器函数可在测试中注入。该方法需等待用户完成操作，是唯一不受默认 30 秒超时限制的一元调用；调用方发出的中止信号和连接中止仍会传播至原生进程。浏览器载体另行将这一特权方法限制为仅接受来自回环地址的同源请求。 -`session.history` 按消息边界分页，其尾页（不带 `beforeSeq`）额外携带两项页窗口本身无法提供的会话级数据：进行中局部消息的 chunk 事件，以及 `todos`——整份日志上最后一次 `todo/write` 的整表投影。较早的页面不带 `todos`，因为该投影是会话级而非分页级的；尾页响应缺少该字段意味着整份日志中没有任何 `todo/write`，因此客户端要把缺失字段读作空计划，而不是读作「状态未变」。 +`session.history` 按消息边界分页，其尾页（不带 `beforeSeq`）携带页窗口本身无法提供的会话级投影：进行中局部消息的分片事件；`todos`，即最后一次 `todo/write` 的整表投影；以及 `metrics`，即按 `(turn, step)` 去重的完整日志用量，并在可用时包含当前 token 计量压力和所选精确路由的容量。较早的页面省略会话级投影。实时 `session/metrics` mux 帧携带单调递增的日志修订号与投影修订号，因此客户端会拒绝陈旧帧，并在向前加载较早页面时保留计数器。缓存读取与缓存写入保持为彼此独立的计数项；缓存命中率的分母是未缓存输入加缓存读取。 `command.*` 与 `skill.*` 领域向客户端暴露宿主命令注册表和技能目录。每个方法都通过 `sessionId` 寻址一个会话的 Agent（被服务的会话必有 Agent；`command.*` 经由与 `session.*` 相同的路径恢复冷会话，而 `skill.list` 从会话头解析项目根目录，不触碰 Agent 注册表）。`command.execute` 在宿主侧运行一条斜杠命令行并返回脱耦结果；载体的请求信号可取消正在运行的处理器。`host/commands-changed` 是目录失效帧：客户端重新拉取 `command.list` 而不是做差分。 diff --git a/packages/host/apiproxy/src/api-proxy.ts b/packages/host/apiproxy/src/api-proxy.ts index 58922284be..13aa85c1fe 100644 --- a/packages/host/apiproxy/src/api-proxy.ts +++ b/packages/host/apiproxy/src/api-proxy.ts @@ -40,6 +40,7 @@ import type { } from '@deepseek-ai/dsh-user-interaction' import { UserInteractionError } from '@deepseek-ai/dsh-user-interaction' import { pickNativeDirectory } from './native-directory-picker.ts' +import { affectsSessionMetrics, SessionMetricsProjector } from './session-metrics.ts' /** Page size when history is called without maxMessages. */ const DEFAULT_MAX_MESSAGES = 50 @@ -417,6 +418,54 @@ export function createApiProxy(ctx: Context, defaults: ApiProxyDefaults): ApiPro for (const queue of muxQueues) queue.push(envelope) } + const pendingMetricSessions = new Set() + let metricFlushScheduled = false + let metricsDisposed = false + const metricsProjector = new SessionMetricsProjector( + ctx, + agent => targetFor(agent).current, + (agent) => { scheduleMetrics(agent.session) }, + ) + + /** Queue one full-log metrics publication after synchronous session listeners drain. */ + function scheduleMetrics(session: Session): void { + if (metricsDisposed || muxQueues.size === 0) return + pendingMetricSessions.add(session) + if (metricFlushScheduled) return + metricFlushScheduled = true + queueMicrotask(() => { + metricFlushScheduled = false + if (metricsDisposed) { + pendingMetricSessions.clear() + return + } + const sessions = [...pendingMetricSessions] + pendingMetricSessions.clear() + for (const current of sessions) { + broadcast({ + type: 'session/metrics', + sessionId: current.id, + metrics: metricsProjector.snapshot(current, ctx.agents.get(current.id)), + }) + } + }) + } + + ctx.effect(() => { + const disposers = [ + ctx.on('session/event', (session: Session, event: SessionEvent) => { + if (affectsSessionMetrics(event)) scheduleMetrics(session) + }), + ctx.on('agent/created', (agent: Agent) => { scheduleMetrics(agent.session) }), + ctx.on('session/disposed', (session: Session) => { pendingMetricSessions.delete(session) }), + ] + return () => { + metricsDisposed = true + pendingMetricSessions.clear() + for (const dispose of disposers) dispose() + } + }, 'api-proxy: session metrics') + /** * Per-session inbox mirror serving the mux-open queue snapshot (the same * refresh-recovery baseline as pending questions).

Cache-write tokens also risk being folded into a cache-hit formula whose denominator has different semantics. +A Web stats line derived from the currently loaded conversation nodes is window-dependent under pagination. Compaction can replace visible content without preserving historical usage, while the selected model does not prove that a request used its route or capacity. Cache-write tokens also risk being folded into a cache-hit formula whose denominator has different semantics. ## Decision The Host owns one session-level metrics projection. It incrementally folds the complete durable event log, keys settled usage by `(turn, step)`, and replaces an earlier usage record for the same key instead of double-counting chunk and message forms. Uncached input, output, cache reads, and cache writes remain four disjoint cumulative buckets. Compaction can change the current prompt surface without erasing historical usage. -Current context pressure is a separate point-in-time value from `tokenMeter.measure(session).totalTokens`. Capacity comes only from `llm.resolveModelInfo(provider, model).context.contextWindow` for the agent's selected route. A route change immediately publishes metrics with capacity absent, then publishes the resolved capacity behind a route generation fence; stale metadata cannot label the new route. +Current context pressure is the point-in-time `tokenMeter.measure(session).totalTokens`. Capacity instead belongs to the latest model request observed by the current live mux connection. `LlmService.prepareCall()` retains the context metadata obtained by the exact lookup that also validates reasoning/defaults, and the loop publishes it through one contained `agent/model-request` notification only after the final route has a successfully constructed stream handle. Failed or aborted iteration still counts as a dispatched request; preparation and synchronous construction failures do not. -The tail `session.history` response carries the projection, while older pages omit it. Live changes use `session/metrics` mux frames. Both forms carry a durable-log revision and a projection revision; the client accepts only nondecreasing revisions, preserves metrics across older-page prepend, and clears them at a new subscription baseline. Missing measurement or metadata stays absent. +The tail `session.history` response carries durable usage and pressure, while older pages omit them. Live changes use `session/metrics` mux frames. Both forms carry a durable-log revision and a projection revision; the client accepts only nondecreasing revisions and preserves metrics across older-page prepend. -The Web stats line treats the projection as its sole token source. It renders uncached input, output, and cache reads separately, computes cache hit as `cacheRead / (uncachedInput + cacheRead)`, and shows current context as a percentage of the exact route capacity. Cache writes never enter that percentage. Visible nodes continue to supply only turn and step counts. +ApiProxy forwards each notification as a distinct `session/model-request` frame only to mux connections already open when dispatch occurs. It never places the frame in `session.history` or a subscription baseline. The client retains that connection-local capacity across ordinary metrics updates, replaces or explicitly clears it on the next observed request, and clears it on `session/subscribed`; reconnect, restore, and a new subscription therefore start unknown until another request is observed. + +The Web stats line treats the durable projection plus live capacity overlay as its sole token source.

The consumer surface (`ctx.llm.stream()`) and the `llm/stream` waterfall are described in [architecture.md § Content blocks and streaming](../architecture.md#content-blocks-and-streaming-dsh-llm). ```ts type-equiv /** One model call whose config and adapter registration were resolved together. */ interface PreparedLlmCall { /** Detached, deep-frozen config with any adapter-owned default materialized. */ readonly config: LlmCallConfig + /** Detached context metadata resolved with the registration-bound call. */ + readonly context?: LlmModelContext /** * Dispatch this call once through the registration captured during * preparation.

The Session separately retains capacity from the latest `session/model-request` observed on its current mux connection and overlays it onto metrics across ordinary usage/pressure updates. A later request replaces or clears that value, while `session/subscribed` clears both metrics ordering and capacity; reconnect, restore, and a new subscription therefore show no percentage until another request is observed. Missing metrics remain `null` rather than being inferred from the visible node window. ## Workspace and Session lists diff --git a/packages/client/runtime/README.zh.md b/packages/client/runtime/README.zh.md index 85d444ee5d..9936256140 100644 --- a/packages/client/runtime/README.zh.md +++ b/packages/client/runtime/README.zh.md @@ -2,7 +2,7 @@ [English](README.md) | 中文 -客户端 cordis 启动与不依赖 React 的对象服务：SlotsService 包装 SlotCore 并提供 renderer 数据源；SessionsService 拥有 Session 对象、列表／scope／history 状态；WorkspacesService 依赖 SessionsService，拥有 Workspace 对象、列表／操作、默认目标派生，以及 New Session 空会话复用入口（`connectWorkspace`）。运行时把共享 Host 流分发给两个 manager。客户端 Session 一律由 Host 出生（一次 `session.create` 同瞬产出 Session+Agent+cwd）；客户端不持有任何实体化之前的会话状态——Agent scope（host dsh-scope 的客户端镜像，以 agent/session 共用 id 为键）在会话行进入列表镜像时出生，随 prune 死亡。契约：api-contracts v3 §4。`ConversationSnapshot` 携带两项由 Host 拥有的完整日志投影。`todos` 来自 history 尾页，在向前加载较早页面时保留，并随实时 `todo/write` 事件更新。`metrics` 来自 history 尾页和实时 `session/metrics` 帧，在向前加载较早页面时保留，并且只接受日志修订号与投影修订号均不减小的数据；订阅基线会在回放前将其清除，使新的流代次可以安全地从头开始计数修订号。缺失的 metrics 保持为 `null`，而不是根据可见节点窗口推断。 +客户端 cordis 启动与不依赖 React 的对象服务：SlotsService 包装 SlotCore 并提供 renderer 数据源；SessionsService 拥有 Session 对象、列表／scope／history 状态；WorkspacesService 依赖 SessionsService，拥有 Workspace 对象、列表／操作、默认目标派生，以及 New Session 空会话复用入口（`connectWorkspace`）。运行时把共享 Host 流分发给两个 manager。客户端 Session 一律由 Host 出生（一次 `session.create` 同瞬产出 Session+Agent+cwd）；客户端不持有任何实体化之前的会话状态——Agent scope（host dsh-scope 的客户端镜像，以 agent/session 共用 id 为键）在会话行进入列表镜像时出生，随 prune 死亡。契约：api-contracts v3 §4。`ConversationSnapshot` 携带两项由 Host 拥有的完整日志投影。`todos` 来自 history 尾页，在向前加载较早页面时保留，并随实时 `todo/write` 事件更新。持久 `metrics` 来自 history 尾页和实时 `session/metrics` 帧，在向前加载较早页面时保留，并且只接受日志修订号与投影修订号均不减小的数据。Session 另行保留当前 mux 连接观察到的最新 `session/model-request` 容量，并在普通用量／压力更新期间把它覆盖到 metrics 上。后续请求会替换或清除该值，`session/subscribed` 则同时清除指标顺序状态与容量；因此，重连、恢复和新订阅都不会显示百分比，直到观察到另一次请求。缺失的 metrics 保持为 `null`，而不是根据可见节点窗口推断。 ## Workspace 与 Session 列表 diff --git a/packages/client/runtime/src/client/sessions/conversation.ts b/packages/client/runtime/src/client/sessions/conversation.ts index 202ddf7df2..4ced165e7a 100644 --- a/packages/client/runtime/src/client/sessions/conversation.ts +++ b/packages/client/runtime/src/client/sessions/conversation.ts @@ -12,6 +12,15 @@ import type { PendingInteraction } from './pending.ts' export type { TodoItem } +/** + * Durable Host metrics with the latest capacity observed on this live mux + * connection overlaid for presentation. + */ +export interface ConversationMetrics extends SessionMetrics { + /** Latest dispatched-request capacity; absent until observed or after reset/clear. */ + contextWindow?: number +} + /** Assistant content blocks sorted by what the UI cares about * (text body / collapsible reasoning / tool-call card head / other fallback). */ export type AssistantBlock = @@ -247,9 +256,9 @@ export interface ConversationSnapshot { * write (last write wins); empty = the log holds no plan. */ todos: readonly TodoItem[] /** - * Host-owned cumulative usage and current-context projection.

The prepared call retains the exact adapter registration across this asynchronous resolution, `request/header` logging, and terminal dispatch, so HMR cannot mix one adapter's capability result with another adapter's request. After the final stream handle is constructed and before adapter iteration, the loop emits one contained live `agent/model-request` notification with turn, step, final provider/model, and optional registration-bound capacity. Preparation or synchronous stream-construction failures emit nothing; later failure or abortion remains an observed dispatch. The effective config is logged before dispatch, so a listener can change effort between steps without hidden request drift. A route with no registered adapter preserves the proposed config so an `llm/stream` listener can own and short-circuit it; unhandled terminal dispatch still fails with `NO_ADAPTER`. A new loop instance restores the last effort only when its initial provider/model route exactly matches the logged route; a route change discards that opaque model-owned ID and resolves the new model independently. Plugin failure ends the current turn, not the loop. Only final adapter dispatch/iteration failures and terminal in-band error or aborted finishes enter `agent/request-error`; middleware, result processing, tools, and other extension failures close directly. Recovery receives the exact live error, immutable provider facts, immutable prior failures, the immutable retry policy of the adapter registration that served the request, and the turn signal after the failed step closes; the policy is absent if no final adapter served it. A handling listener returns `{ kind: 'retry' }`; the loop closes the failed turn with its error and opens one numbered retry turn without an intervening idle notification. Success clears the consecutive history, and an unhandled failure is terminal. AgentLoop owns one cancellation signal for the current admission or turn. An effective `cancel(cause)` clears pending work unless `keepInbox` is set and cooperatively aborts that signal; idle cancellation is a no-op.

Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `command.execute` runs a slash-command line host-side and returns a detached result; the carrier's request signal cancels the running handler. `host/commands-changed` is the catalog invalidation frame: clients refetch `command.list` instead of diffing. diff --git a/packages/host/apiproxy/README.zh.md b/packages/host/apiproxy/README.zh.md index 2aae0bd683..4e52058c17 100644 --- a/packages/host/apiproxy/README.zh.md +++ b/packages/host/apiproxy/README.zh.md @@ -20,7 +20,9 @@ Workspace 列表与 Session 列表是相互独立的重连基线。`workspace.cr `host.openPath` 会用操作系统的默认应用打开一个文件系统路径（macOS 为 `open`，Windows 为 `Invoke-Item`，Linux 为 `xdg-open`）。打开器可在测试中注入。浏览器载体对其施加与 `host.pickDirectory` 相同的回环、同源限制。 -`session.history` 按消息边界分页，其尾页（不带 `beforeSeq`）携带页窗口本身无法提供的会话级投影：进行中局部消息的分片事件；`todos`，即最后一次 `todo/write` 的整表投影；以及 `metrics`，即按 `(turn, step)` 去重的完整日志用量，并在可用时包含当前 token 计量压力和所选精确路由的容量。较早的页面省略会话级投影。实时 `session/metrics` mux 帧携带单调递增的日志修订号与投影修订号，因此客户端会拒绝陈旧帧，并在向前加载较早页面时保留计数器。缓存读取与缓存写入保持为彼此独立的计数项；缓存命中率的分母是未缓存输入加缓存读取。 +`session.history` 按消息边界分页，其尾页（不带 `beforeSeq`）携带页窗口本身无法提供的会话级投影：进行中局部消息的分片事件；`todos`，即最后一次 `todo/write` 的整表投影；以及 `metrics`，即按 `(turn, step)` 去重的完整日志用量与当前 token 计量压力。较早的页面省略会话级投影。实时 `session/metrics` mux 帧携带单调递增的日志修订号与投影修订号，因此客户端会拒绝陈旧帧，并在向前加载较早页面时保留计数器。缓存读取与缓存写入保持为彼此独立的计数项；缓存命中率的分母是未缓存输入加缓存读取。 + +上下文容量使用独立的临时 `session/model-request` mux 帧；实际请求到达分派点后，该帧由失败会被收容的 Agent 通知发出。该帧携带轮次、步骤、最终提供方／模型与可选容量，且只发送给当时已经打开的 mux 连接。`session.history`、mux 订阅基线、重连和会话恢复绝不会查询或回放先前的容量；不带容量的帧会显式清除较早的连接本地值。 `command.*` 与 `skill.*` 领域向客户端暴露宿主命令注册表和技能目录。每个方法都通过 `sessionId` 寻址一个会话的 Agent（被服务的会话必有 Agent；`command.*` 经由与 `session.*` 相同的路径恢复冷会话，而 `skill.list` 从会话头解析项目根目录，不触碰 Agent 注册表）。`command.execute` 在宿主侧运行一条斜杠命令行并返回脱耦结果；载体的请求信号可取消正在运行的处理器。`host/commands-changed` 是目录失效帧：客户端重新拉取 `command.list` 而不是做差分。 diff --git a/packages/host/apiproxy/src/api-proxy.ts b/packages/host/apiproxy/src/api-proxy.ts index 440c3a1694..a9a753db66 100644 --- a/packages/host/apiproxy/src/api-proxy.ts +++ b/packages/host/apiproxy/src/api-proxy.ts @@ -6,7 +6,6 @@ import { randomUUID } from 'node:crypto' import { mkdir, stat } from 'node:fs/promises' import { join } from 'node:path' -import { FiberState } from 'cordis' import type { Context } from 'cordis' import { installAgentLlmTarget } from '@deepseek-ai/dsh-agent' import type { @@ -409,26 +408,6 @@ export function createApiProxy(ctx: Context, defaults: ApiProxyDefaults): ApiPro return target } - /** - * Read the best capacity route without taking ownership of foreign routing. - * Web agents expose their live selection; other agents expose only a route - * that already crossed the durable request-header boundary. - */ - function metricsRouteFor(agent: Agent): Pick | undefined { - const installed = targets.get(agent) - if (installed !== undefined) return installed.current - const logged = agent.session.requestHeader()?.config - return logged === undefined - ?

Plugin failure ends the current turn, not the loop. Only final adapter dispatch/iteration failures and terminal in-band error or aborted finishes enter `agent/request-error`; middleware, result processing, tools, and other extension failures close directly. Recovery receives the exact live error, immutable provider facts, immutable prior failures, the immutable retry policy of the adapter registration that served the request, and the turn signal after the failed step closes; the policy is absent if no final adapter served it. A handling listener returns `{ kind: 'retry' }`; the loop closes the failed turn with its error and opens one numbered retry turn without an intervening idle notification. Success clears the consecutive history, and an unhandled failure is terminal. AgentLoop owns one cancellation signal for the current admission or turn. An effective `cancel(cause)` clears pending work unless `keepInbox` is set and cooperatively aborts that signal; idle cancellation is a no-op. Durable `turn/end` records `aborted` for `user` and `parent`, while disposal records `disposed`; undispatched model tool calls receive synthetic `tool/call` and `ABORTED_BEFORE_DISPATCH` result pairs. The cancellation cause changes reporting, not how result context finalized after cancellation is handled. Disposal waits for signal-ignoring work before registry removal.

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: '', 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). diff --git a/packages/client/ui-conversation/README.zh.md b/packages/client/ui-conversation/README.zh.md index ffbeace6d5..68128c7a4c 100644 --- a/packages/client/ui-conversation/README.zh.md +++ b/packages/client/ui-conversation/README.zh.md @@ -10,7 +10,7 @@ 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。 -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。前端倒计时由计划延迟派生，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，完成后则稳定显示为静态的已完成标签。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。 +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: '', 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）。 diff --git a/packages/client/ui-conversation/src/client/chat/ChatView.tsx b/packages/client/ui-conversation/src/client/chat/ChatView.tsx index c45c6f1c8c..cafbf4dfcd 100644 --- a/packages/client/ui-conversation/src/client/chat/ChatView.tsx +++ b/packages/client/ui-conversation/src/client/chat/ChatView.tsx @@ -50,7 +50,7 @@ function activeRetrySeq(nodes: readonly ConversationNode[], running: boolean): n for (let index = nodes.length - 1; index >= 0; index -= 1) { const node = nodes[index] if (node === undefined) continue - if (node.kind === 'model-retry') return node.seq + if (node.kind === 'model-retry') return node.retryState === 'cancelled' ? null : node.seq if (node.kind === 'assistant' || node.kind === 'user') return null } return null diff --git a/packages/client/ui-conversation/src/client/chat/MessageItem.tsx b/packages/client/ui-conversation/src/client/chat/MessageItem.tsx index cdd0efacad..5c3c99d1e0 100644 --- a/packages/client/ui-conversation/src/client/chat/MessageItem.tsx +++ b/packages/client/ui-conversation/src/client/chat/MessageItem.tsx @@ -4,7 +4,7 @@ // off the snapshot cache; memo holds across streaming because unchanged nodes // keep their references. -import { memo, useCallback, useEffect, useState, type ReactNode } from 'react' +import { memo, useCallback, useEffect, useMemo, useState, type ReactNode } from 'react' import type { ContextMessageNode, ModelRetryNode, SteeringMessageNode, UnknownSurfaceNode, UserMessageNode, } from '@deepseek-ai/dsh-client-runtime/client' @@ -40,7 +40,9 @@ interface RetryCountdown { } function ModelRetryItem({ node, active }: { node: ModelRetryNode; active: boolean }) { - const deadline = node.time + node.delayMs + // Anchor the host-scheduled delay to this browser's first render of the + // retry node.

[中文](2026-07-28-host-owned-web-session-metrics.zh.md) - -## Problem - -A Web stats line derived from the currently loaded conversation nodes is window-dependent under pagination. Compaction can replace visible content without preserving historical usage, while the selected model does not prove that a request used its route or capacity. Cache-write tokens also risk being folded into a cache-hit formula whose denominator has different semantics. - -## Decision - -The Host owns one session-level metrics projection. It incrementally folds the complete durable event log, keys settled usage by `(turn, step)`, and replaces an earlier usage record for the same key instead of double-counting chunk and message forms. Uncached input, output, cache reads, and cache writes remain four disjoint cumulative buckets. Compaction can change the current prompt surface without erasing historical usage. - -Current context pressure is the point-in-time `tokenMeter.measure(session).totalTokens`. Capacity instead belongs to the latest model request attempt observed by the current live mux connection. `LlmService.prepareCall()` retains the context metadata obtained by the exact lookup that also validates reasoning/defaults. After the final provider/model is fixed and the outer `llm/stream` call returns a handle, the loop publishes one contained `agent/model-request` notification. This boundary observes an attempt, not proof of provider I/O: preparation or a synchronous outer waterfall failure emits nothing, while short-circuit handles and later lazy adapter construction, iteration failure, or abort still count. - -The tail `session.history` response carries durable usage and pressure, while older pages omit them. Live changes use `session/metrics` mux frames. Both forms carry a durable-log revision and a projection revision; the client accepts only nondecreasing revisions and preserves metrics across older-page prepend. - -ApiProxy forwards each notification as a distinct `session/model-request` frame only to mux connections already open when dispatch occurs. It never places the frame in `session.history` or a subscription baseline. The client keeps durable `metrics` and transient `modelRequestContextWindow` as separate snapshot fields, replaces or explicitly clears the capacity on the next observed request, and clears both fields on `session/subscribed`; reconnect, restore, and a new subscription therefore start unknown until another request is observed. - -The Web stats line joins the durable projection and live capacity only at presentation. It renders uncached input, output, and cache reads separately, computes cache hit as `cacheRead / (uncachedInput + cacheRead)`, and shows current context as a percentage only when the current connection observed a capacity. Cache writes never enter that percentage. Visible nodes continue to supply only turn and step counts. - -## Alternatives considered - -**Fold the loaded node window in React.** This cannot survive pagination or compaction and duplicates durable-log semantics in a presentation package. - -**Send usage only with raw assistant events.** Reconnect and older-page stitching would still need the client to reconstruct a full-log aggregate, and duplicate usage forms would need protocol-specific repair there. - -**Reuse one total-token field for cache hit.** Cache reads, cache writes, and uncached input represent distinct provider accounting buckets; combining them would make the displayed rate misleading. - -**Query the selected route before dispatch.** Selection may never produce a request, and a second metadata lookup can race the registration-bound lookup that actually validates and dispatches the call. - -**Persist or replay the latest request capacity.** That would make a former request look current on reconnect or restore even though the new connection observed no request. The denominator is deliberately live and opportunistic. - -## Consequences - -Token totals remain stable across pagination, replay, compaction, and browser reconnect. The client stores a small detached durable projection plus one connection-local denominator instead of scanning the conversation window, and the status row remains readable for large histories through compact number formatting. - -The Host performs one incremental log fold per session and schedules durable projection updates only for usage, request-header, or surface-changing events; text and reasoning deltas do not publish metrics. A new connection omits the percentage until it observes a request with context metadata. A later request without metadata clears the denominator, while deployments without a token meter still retain the durable counters and label context unavailable instead of fabricating pressure. diff --git a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md b/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md deleted file mode 100644 index 4535fd8a4b..0000000000 --- a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md +++ /dev/null @@ -1,39 +0,0 @@ -# Agent Note: Host 拥有的 Web 会话指标 - -Status: implemented - -[English](2026-07-28-host-owned-web-session-metrics.md) | 中文 - -## 问题 - -Web 统计行若根据当前加载的会话节点推导指标，其结果会随分页窗口变化。压缩（compaction）可以替换可见内容，却无法保留历史用量；所选模型也不能证明某次请求实际采用了该模型的路由或容量。缓存写入 token 还可能被计入缓存命中率公式，而该公式的分母具有不同语义。 - -## 决策 - -Host 拥有一项会话级指标投影。它以增量方式归并完整的持久事件日志，按 `(turn, step)` 标识已结算用量；同一标识再次出现时，会替换较早的用量记录，而不会重复统计分片和消息两种形态。未缓存输入、输出、缓存读取与缓存写入保持为四个彼此独立的累计计数项。压缩可以改变当前提示词表层，但不会抹除历史用量。 - -当前上下文压力是即时的 `tokenMeter.measure(session).totalTokens`。容量则属于当前实时 mux 连接观察到的最新模型请求尝试。`LlmService.prepareCall()` 会保留同一次精确查询取得的上下文元数据，该查询也负责校验推理设置与默认值。最终提供方／模型确定且外层 `llm/stream` 调用返回句柄后，循环会发布一条 `agent/model-request` 通知，并收容该通知的失败。这个边界观察到的是一次尝试，并不能证明提供方 I/O 已开始：准备阶段或外层 waterfall（瀑布式事件）的同步失败不会发出通知，而短路句柄以及之后的惰性适配器构造、迭代失败或中止仍会计入。 - -`session.history` 尾页响应携带持久用量与压力，较早页面则省略这两项。实时变更使用 `session/metrics` mux 帧。两种形式都携带持久日志修订号和投影修订号；客户端只接受不减小的修订号，并在向前加载较早页面时保留指标。 - -ApiProxy 只把每条通知作为独立的 `session/model-request` 帧转发给分派发生时已经打开的 mux 连接。它绝不会把该帧放入 `session.history` 或订阅基线。客户端把持久 `metrics` 与临时 `modelRequestContextWindow` 保存在彼此独立的快照字段中，在观察到下一次请求时替换或显式清除容量，并在收到 `session/subscribed` 时清除这两个字段；因此，重连、恢复和新订阅都会从未知容量开始，直到观察到另一次请求。 - -Web 统计行只在展示时结合持久投影与实时容量。它分别呈现未缓存输入、输出与缓存读取，通过 `cacheRead / (uncachedInput + cacheRead)` 计算缓存命中率，并且只有当前连接观察到容量时，才把当前上下文显示为该容量的百分比。缓存写入绝不计入缓存命中率。可见节点仍然只提供轮次和步骤计数。 - -## 备选方案 - -**在 React 中归并已加载的节点窗口。** 此方案无法跨越分页或压缩保留数据，还会在展示包中重复实现持久日志语义。 - -**只随原始 assistant 事件发送用量。** 重连和较早页面拼接仍会要求客户端重建完整日志聚合，而且重复的用量形态需要在客户端按协议专门修复。 - -**为缓存命中率复用单一的 token 总数字段。** 缓存读取、缓存写入与未缓存输入是提供方记账中的不同计数项；将它们合并会使显示的比率产生误导。 - -**在分派前查询所选路由。** 选择操作可能永远不会产生请求；第二次元数据查询还可能与实际校验并分派调用的、绑定注册项的查询发生竞态。 - -**持久化或回放最新请求的容量。** 即使新连接没有观察到任何请求，这也会让先前请求在重连或恢复后显得仍然有效。该分母刻意只采用实时且恰好可得的数据。 - -## 后果 - -token 总量在分页、回放、压缩和浏览器重连期间保持稳定。客户端存储一项小型、脱耦的持久投影与一个连接本地分母，无需扫描会话窗口；状态行采用紧凑数字格式，因此在较长的历史记录中仍然清晰易读。 - -Host 为每个会话执行一次增量日志归并，仅为用量事件、请求头事件或表层变更事件调度持久投影更新；文本与推理（reasoning）增量不会发布指标。新连接在观察到带上下文元数据的请求之前不会显示百分比。后续不带元数据的请求会清除该分母；未部署 token 计量器时，系统仍保留持久计数器，并把上下文标示为不可用，而不会虚构压力值。 diff --git a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.i18n.yaml b/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.i18n.yaml similarity index 52% rename from .agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.i18n.yaml rename to .agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.i18n.yaml index 8c72912377..6aa9498b9c 100644 --- a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.i18n.yaml +++ b/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.i18n.yaml @@ -1,6 +1,6 @@ # Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each # side as of the last confirmed-consistent state.

Compaction can replace visible content without preserving historical usage. Conversely, context occupancy describes one real request boundary: a selected model is only an intention, and combining token pressure from one moment with capacity resolved for another route creates a false percentage. + +These two values therefore have different lifetimes. Provider-reported billing is durable, replayable session state. Request pressure and registration-bound capacity are an opportunistic live observation that must disappear across a connection generation. + +## Decision + +`@deepseek-ai/dsh-token-meter` registers the generic `tokenUsage` session projection when `ctx.sessionProjections` is present. The projection folds the complete durable log into uncached input, output, cache-read, and cache-write buckets. An `assistant/chunk` usage sample survives a later failed request; an `assistant/message` usage value replaces the earlier value for the same `(turn, step)` instead of being counted twice. Reasoning tokens remain an output subdivision and are not added again. Compaction and surface replacement do not erase earlier billing. + +The projection uses the standard projection lifecycle and wire path. History tail baselines, `session/projection` live frames, higher-seq-wins client storage, JSON checkpoints, cache recovery, and unit unload all remain generic. There is no token-specific history field, mux frame, projector, revision counter, or client fence. + +`LlmService.prepareCall()` retains context metadata from the exact lookup that also validates reasoning and captures the adapter registration. After the outer stream call returns its handle and before iteration begins, AgentLoop emits one contained `agent/model-request` notification. Preparation or a synchronous outer waterfall failure emits nothing; short-circuit handles and later iterator construction, iteration, or abort failures still count as an observed request attempt. + +ApiProxy handles that notification synchronously. It reads `tokenMeter.measure(agent.session).totalTokens` once when the optional service is present and combines the result with the same prepared call's registration-bound `contextWindow`. It broadcasts one atomic `session/model-request` frame containing the route, turn, step, and whichever of `contextTokens` and `contextWindow` are available. Measurement failure omits only the numerator. The frame goes only to mux connections already open at that instant; history, subscription baselines, reconnect, and restore never replay it. + +The client stores the complete latest request frame as `ConversationSnapshot.modelRequest`. Every later frame replaces the entire snapshot, so omitted fields clear earlier values. `SessionManager` temporarily holds a pre-instantiation frame, while a new subscription generation, disconnect, or session removal clears both resident and pending values. Model selection alone does not change this snapshot. + +The Web `StatsLine` reads `tokenUsage` through the standard `useProjection` hook and reads request telemetry plus visible nodes through `useSession`. It renders uncached input, output, and cache reads separately, computes cache hit as `cacheRead / (uncachedInput + cacheRead)`, and shows context occupancy only when one request snapshot contains both numerator and capacity. Visible nodes continue to supply only turn and step counts. The existing inline text UI is retained; the model selector gains no circle or other accessory. + +## Alternatives considered + +**A custom session metrics history field and mux frame.** This duplicated the generic projection protocol, cache, recovery, and seq fencing while coupling durable billing to transient request pressure. + +**Fold the loaded node window in React.** This cannot survive pagination or compaction and makes a presentation package reconstruct log semantics. + +**Publish usage only with final assistant messages.** A request that reports a usage chunk and then fails would lose provider billing. + +**Query capacity from the selected model.** Selection may never produce a request, and a second metadata lookup can disagree with the registration-bound lookup used by the actual call. + +**Persist or replay the latest request snapshot.** A request from a prior connection would appear current after restore even though no new request was observed. + +**Add a context circle beside the model selector.** That placement suggests selected-model state. The existing stats line expresses the request-scoped semantics without introducing a duplicate UI or data path. + +## Consequences + +Token totals stay stable across pagination, compaction, replay, and reconnect because they are ordinary durable projection state. Context occupancy is deliberately unknown after reconnect until a new real request is observed. Deployments without token-meter or without model capacity still publish the request route and clear stale optional fields instead of fabricating a percentage. + +ApiProxy performs one synchronous optional measurement and one frame conversion per observed request. It owns no per-session metrics cache or refresh queue. The browser keeps one generic projection value plus one small connection-local request snapshot, and streaming text deltas do not force the stats line to recompute. diff --git a/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.zh.md b/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.zh.md new file mode 100644 index 0000000000..02b03d1516 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.zh.md @@ -0,0 +1,45 @@ +# Agent Note：token 用量投影与请求上下文 + +Status: implemented + +[English](2026-07-29-projected-token-usage-and-request-context.md) | 中文 + +## 问题 + +Web 统计行若根据当前已加载的会话节点推导，其结果会在分页时依赖当前窗口。压缩（compaction）可以替换可见内容，却不保留历史用量。另一方面，上下文占用率描述的是一个真实请求边界：所选模型只代表意图；若把某一时刻的 token 压力与另一路由解析出的容量组合，就会产生虚假百分比。 + +因此，这两个值具有不同的生命周期。提供方报告的计费用量属于持久、可回放的会话状态。请求压力和与注册项绑定的容量则是恰好可得的实时观测，跨连接代次时必须消失。 + +## 决策 + +当 `ctx.sessionProjections` 存在时，`@deepseek-ai/dsh-token-meter` 会注册通用的 `tokenUsage` 会话投影。该投影将完整持久日志归并为未缓存输入、输出、缓存读取和缓存写入四类计数项。即使后续请求失败，`assistant/chunk` 用量样本仍会保留；同一 `(turn, step)` 的 `assistant/message` 用量值会替换先前值，不会重复计数。推理（reasoning）token 仍是输出的细分项，不会再次累加。压缩和表层替换不会抹除先前的计费用量。 + +该投影使用标准的投影生命周期与协议路径。历史尾页基线、`session/projection` 实时帧、seq 高者胜的客户端存储、JSON 检查点、缓存恢复和单元卸载均保持通用机制。系统没有任何 token 专用的历史字段、mux 帧、投影器、修订计数器或客户端 seq 防护机制。 + +`LlmService.prepareCall()` 会保留精确查询得到的上下文元数据；同一次查询还会校验推理强度并捕获适配器注册项。外层流调用返回句柄后、开始迭代前，AgentLoop 会发出一条失败受收容的 `agent/model-request` 通知。准备阶段或外层 waterfall（瀑布式事件）的同步失败不会发出通知；短路句柄以及之后的迭代器构造失败、迭代失败或中止仍算作一次已观测的请求尝试。 + +ApiProxy 会同步处理该通知。当可选服务存在时，它会读取一次 `tokenMeter.measure(agent.session).totalTokens`，并将结果与同一准备完成调用中绑定注册项的 `contextWindow` 合并。它会广播一个原子 `session/model-request` 帧，其中包含路由、轮次、步骤，以及可用的 `contextTokens`／`contextWindow` 字段。测量失败时只省略分子。该帧只发送给当时已经打开的 mux 连接；历史记录、订阅基线、重连和恢复都绝不回放该帧。 + +客户端将最新的完整请求帧存储为 `ConversationSnapshot.modelRequest`。每个后续帧都会替换整个快照，因此省略字段会清除先前值。`SessionManager` 会临时保存一个实例化前帧；新订阅代次、断开连接或移除会话时，则会同时清除常驻值和待处理值。仅选择模型不会改变该快照。 + +Web `StatsLine` 通过标准 `useProjection` 钩子读取 `tokenUsage`，并通过 `useSession` 读取请求观测数据与可见节点。它分别显示未缓存输入、输出与缓存读取，通过 `cacheRead / (uncachedInput + cacheRead)` 计算缓存命中率，并且只有同一份请求快照同时包含分子与容量时才显示上下文占用率。可见节点仍只提供轮次和步骤计数。系统保留现有的行内文本 UI；模型选择器不增加圆环或其他附属控件。 + +## 备选方案 + +**自定义会话指标历史字段和 mux 帧。** 这会重复实现通用投影协议、缓存、恢复和 seq 防护机制，并将持久计费用量与临时请求压力耦合。 + +**在 React 中归并已加载的节点窗口。** 此方案无法跨分页或压缩保留数据，还会迫使展示包重建日志语义。 + +**仅随最终 assistant 消息发布用量。** 如果请求报告一个用量分片后失败，就会丢失提供方计费用量。 + +**从所选模型查询容量。** 选择操作可能永远不会产生请求；第二次元数据查询还可能与实际调用所用的、绑定注册项的查询不一致。 + +**持久化或回放最新请求快照。** 即使没有观察到任何新请求，先前连接的请求也会在恢复后显得仍是当前请求。 + +**在模型选择器旁增加上下文圆环。** 该位置会让人以为这是所选模型的状态。现有统计行可以表达按请求作用域的语义，无需引入重复的 UI 或数据路径。 + +## 后果 + +token 总量在分页、压缩、回放和重连期间保持稳定，因为它们属于普通的持久投影状态。重连后，上下文占用率会刻意保持未知，直到系统观察到新的真实请求。未部署 token-meter 或模型不提供容量时，系统仍会发布请求路由，并清除陈旧的可选字段，而不会虚构百分比。 + +ApiProxy 会为每次已观测请求执行一次可选的同步测量和一次帧转换。它不拥有任何逐会话指标缓存或刷新队列。浏览器只保留一个通用投影值和一个小型连接本地请求快照；流式文本增量不会迫使统计行重新计算。 diff --git a/apps/web/tests/question-composer.e2e.ts b/apps/web/tests/question-composer.e2e.ts index 6ecdb683b3..8689a74fc2 100644 --- a/apps/web/tests/question-composer.e2e.ts +++ b/apps/web/tests/question-composer.e2e.ts @@ -104,7 +104,7 @@ describe('web e2e: resident question composer round trip', () => { const inner = child.getBoundingClientRect() return Math.max(box.top - inner.top, inner.bottom - box.bottom) }))) - const list = rows[0]?.parentElement ?? null + const list = card.querySelector('[data-question-scroll]') return { rows: rows.length, spill: Math.max(...spill), diff --git a/apps/web/tests/snapshots/code-mode-round/ui.expected.md b/apps/web/tests/snapshots/code-mode-round/ui.expected.md index 4847924619..dccd3fd7dc 100644 --- a/apps/web/tests/snapshots/code-mode-round/ui.expected.md +++ b/apps/web/tests/snapshots/code-mode-round/ui.expected.md @@ -12,6 +12,7 @@ - img - button "编辑": - img +- button "▸ 上下文注入" - 'button "Think The user wants me to write a single `run_code` program that:"': - img - img @@ -28,7 +29,7 @@ - img - text: Think The program ran successfully.

The `/client` export surface is the contract only — `apply`/`inject`, the two service classes, and the `contract/` type families; implementation components (skeleton, chat rows) and the store factory stay internal and reach the page exclusively through apply's slot registrations (tests take them via the `./src/*` subpath). diff --git a/packages/client/ui-conversation/README.zh.md b/packages/client/ui-conversation/README.zh.md index f6dfc3ca61..65c5554a78 100644 --- a/packages/client/ui-conversation/README.zh.md +++ b/packages/client/ui-conversation/README.zh.md @@ -20,7 +20,7 @@ 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 输入栏为 `'conversation.input.plan'`（位于本地 access 模式控件右侧）和 `'conversation.input.model'`（渲染在 pending 指示器与发送／停止按钮之前）声明会话作用域的单实例 seat，并为 overlay、dock、left 和 right 输入扩展声明列表 slot。各功能包拥有相应控件及其状态；ui-conversation 提供放置位置、`locked` owner prop 和标准 slot share。当 `plan` 投影的有效目标为 plan mode 时，InputBar 将文本框 placeholder 切换为 plan 任务措辞（经标准套件 `useProjection` 读取的 host 折叠值；owner 提供的 placeholder 优先）。常驻无会话壳使用 `DisabledInputBar`，因此不会分发任何会话作用域的控件 seat。 -聊天统计行从 `ConversationSnapshot.metrics` 读取持久的 token 计数／当前压力，并且只在展示时把它们与独立的连接本地 `modelRequestContextWindow` 结合；可见节点仅提供既有的轮次和步骤计数。它以相互独立的紧凑值显示未缓存输入、输出与缓存读取，通过 `cacheRead / (uncachedInput + cacheRead)` 计算缓存命中率而不计入缓存写入，并且只有当前 mux 连接观察到带容量的模型请求后才显示上下文占用率。在该请求之前、重连／恢复／新订阅之后，或在请求不带容量之后，系统都会省略百分比，并把上下文标为「未知」，而不会提前查询或根据历史记录重建。 +聊天统计行从通用 `tokenUsage` 投影读取完整日志计费用量，并且只在展示时把它与连接本地的原子快照 `ConversationSnapshot.modelRequest` 结合；可见节点仅提供既有的轮次和步骤计数。它以相互独立的紧凑值显示未缓存输入、输出与缓存读取，通过 `cacheRead / (uncachedInput + cacheRead)` 计算缓存命中率而不计入缓存写入，并且只有同一份已观测请求快照同时包含 `contextTokens` 与 `contextWindow` 时才显示上下文占用率。在该请求之前、重连／恢复／新订阅之后，或在请求缺少任一字段之后，系统都会把上下文标为「未知」，而不会从所选模型查询或根据历史记录重建。现有的行内统计行仍是唯一的上下文 UI；模型选择器不增加圆环或附属控件。 `src/client/` 按未来的包拆分组织：`contract/` 是唯一的跨领域共享表层（`slots.ts` slot 声明 + 组合后的 slot props，包括工具行契约、`views.ts` 共享原语、`tool-call-model.ts`）；`skeleton/`、`chat/` 和 `toolviews/`（示例注册方）领域目录只导入 contract 文件，彼此绝不导入；`apply.ts` 是唯一允许导入全部三个领域的组装点。`/client` 导出表层只包含契约：`apply`／`inject`、两个服务类和 `contract/` 类型家族；实现组件（骨架、聊天行）与 store factory 保持内部状态，只能通过 apply 的 slot 注册到达页面（测试通过 `./src/*` 子路径获取它们）。 diff --git a/packages/client/ui-conversation/package.json b/packages/client/ui-conversation/package.json index 42812dce24..88be12b5af 100644 --- a/packages/client/ui-conversation/package.json +++ b/packages/client/ui-conversation/package.json @@ -44,6 +44,7 @@ "@deepseek-ai/dsh-client-ui-slash": "^0.0.1", "@deepseek-ai/dsh-client-ui-slots": "^0.0.1", "@deepseek-ai/dsh-invariants": "^0.0.1", + "@deepseek-ai/dsh-token-meter": "^0.0.1", "cordis": "^4.0.0-rc.7", "react": "^18.2.0" }, @@ -52,6 +53,7 @@ "@deepseek-ai/dsh-plan-mode": "workspace:^", "@deepseek-ai/dsh-session-projection": "workspace:^", "@deepseek-ai/dsh-tool-todo": "workspace:^", + "@deepseek-ai/dsh-token-meter": "workspace:^", "@deepseek-ai/dsh-client-ui-layout": "workspace:^", "@deepseek-ai/dsh-client-ui-primitives": "workspace:^", "@deepseek-ai/dsh-client-ui-slash": "workspace:^", diff --git a/packages/client/ui-conversation/src/client/chat/ChatView.tsx b/packages/client/ui-conversation/src/client/chat/ChatView.tsx index 1cbb00a4ce..36a2cde7b9 100644 --- a/packages/client/ui-conversation/src/client/chat/ChatView.tsx +++ b/packages/client/ui-conversation/src/client/chat/ChatView.tsx @@ -221,7 +221,9 @@ function StreamingTail({ useSession, onGrow }: { * The chat view slot entry: pure component over the composed props (tool rows * render through the declared keyed hole's renderSlot share). */ -export function ChatView({ useSession, useSessions, useStore, renderSlot, sessionId, openFile, loadOlder }: ChatViewSlotProps) { +export function ChatView({ + useProjection, useSession, useSessions, useStore, renderSlot, sessionId, openFile, loadOlder, +}: ChatViewSlotProps) { const nodes = useSession(s => s.nodes) // Workspace root off the session list row: path summaries display relative to it. const cwd = useSessions(s => s.byId[sessionId]?.cwd) @@ -381,7 +383,7 @@ export function ChatView({ useSession, useSessions, useStore, renderSlot, sessio {running && }

From 48192101426c815dede5a88d0dacf1be77988602 Mon Sep 17 00:00:00 2001 From: Hypatia May Date: Thu, 30 Jul 2026 13:53:08 +0800 Subject: [PATCH 029/278] refactor(token-meter): make context occupancy durable projection state Replace the transient `session/model-request` mux frame with ordinary durable session state. Occupancy now rides two last-wins projection fields instead of a non-replayable frame that needed removal tombstones and cross-stream fencing. The frame was the only non-replayable class on the mux stream. Because host and mux are independent SSE streams with no cross-stream order, a request emitted before a removal could arrive after `host/session-removed`, and a legitimate request for a new lifecycle reusing the same id could be fenced by a late removal. Fixing that needed a lifecycle generation on every frame; the frame itself was the problem. Removed: the `session/model-request` frame and schema, the `agent/model-request` core event, the ApiProxy measurement point, the client-side telemetry map and removal tombstone, and the synthetic `cancelled` open error used to signal reconnect through the error channel. Added: `request/context`, a log-only session event recording the registration-bound capacity of the route a request resolved to, appended beside `request/header` from the lookup that already prepared the call and skipped when the route is unchanged. Capacity stays out of `EpochHeader` because it is adapter metadata about a route, not an input the request was built from, so it must not join request reconstruction or header equality. The `contextPressure` projection pairs the newest provider-reported prompt size with the newest recorded capacity. The two are deliberately not one atomic request observation: switching models can pair a fresh capacity with the prior route's pressure until the next request reports usage. The figure is a user-facing reference, and this matches how the TUI status line has always computed occupancy. --- packages/client/connection/src/client/api.ts | 2 +- .../connection/src/client/connection.ts | 26 +- .../client/connection/src/client/fixture.ts | 76 ++++- .../client/connection/src/client/index.ts | 6 +- .../connection/tests/connection.spec.ts | 78 ++--- .../client/connection/tests/fixture.spec.ts | 28 +- packages/client/runtime/README.i18n.yaml | 4 +- packages/client/runtime/README.md | 4 +- packages/client/runtime/README.zh.md | 4 +- packages/client/runtime/src/client/index.ts | 6 +- .../src/client/sessions/conversation.ts | 7 +- .../runtime/src/client/sessions/manager.ts | 34 +- .../runtime/src/client/sessions/session.ts | 115 ++----- .../client/runtime/tests/client-apply.spec.ts | 54 --- packages/client/runtime/tests/fake-api.ts | 9 +- packages/client/runtime/tests/manager.spec.ts | 222 ------------ .../client/runtime/tests/queue-store.spec.ts | 7 - packages/client/runtime/tests/session.spec.ts | 317 +----------------- packages/client/test-runtime/src/fixtures.ts | 1 - .../src/client/chat/ChatView.tsx | 16 +- .../src/client/chat/StatsLine.tsx | 40 +-- .../tests/chat-branch-tails.spec.tsx | 18 +- .../tests/chat-code-subcalls.spec.tsx | 2 +- .../ui-conversation/tests/chat-view.spec.tsx | 13 +- .../tests/gate-branch-tails.spec.tsx | 20 +- .../ui-conversation/tests/input-bar.spec.tsx | 2 +- .../tests/input-matrix.spec.tsx | 2 +- .../tests/input-scenarios.spec.tsx | 2 +- .../ui-conversation/tests/queue-dock.spec.tsx | 2 +- .../ui-conversation/tests/skeleton.spec.tsx | 2 +- .../ui-conversation/tests/todo-panel.spec.tsx | 3 +- packages/core/agent-loop/README.i18n.yaml | 4 +- packages/core/agent-loop/README.md | 2 +- packages/core/agent-loop/README.zh.md | 4 +- packages/core/agent-loop/src/agent.ts | 31 +- .../tests/request-reconstruction.spec.ts | 142 +------- packages/core/agent/README.i18n.yaml | 4 +- packages/core/agent/README.md | 2 +- packages/core/agent/README.zh.md | 2 +- packages/core/agent/src/types.ts | 24 -- .../core/scope/src/scoped-events.generated.ts | 1 - packages/core/scope/tests/invariant.spec.ts | 1 - packages/core/session/src/index.ts | 26 +- packages/core/session/src/invariant.ts | 1 + packages/core/session/src/types.ts | 24 ++ packages/host/apiproxy/README.i18n.yaml | 4 +- packages/host/apiproxy/README.md | 4 - packages/host/apiproxy/README.zh.md | 4 - packages/host/apiproxy/package.json | 7 - packages/host/apiproxy/src/api-proxy.ts | 29 +- .../host/apiproxy/src/api/events.schema.ts | 14 +- packages/host/apiproxy/src/api/events.ts | 30 -- packages/host/apiproxy/src/api/index.ts | 7 +- .../host/apiproxy/src/api/sessions.schema.ts | 2 +- packages/host/apiproxy/src/api/sessions.ts | 8 +- .../tests/api-proxy-model-request.spec.ts | 124 ------- .../host/apiproxy/tests/rpc-schemas.spec.ts | 28 +- packages/host/apiproxy/tsconfig.json | 3 - packages/llm/token-meter/src/index.ts | 3 +- packages/llm/token-meter/src/projection.ts | 27 +- .../llm/token-meter/src/usage-projection.ts | 57 +++- pnpm-lock.yaml | 3 - 62 files changed, 382 insertions(+), 1362 deletions(-) delete mode 100644 packages/host/apiproxy/tests/api-proxy-model-request.spec.ts diff --git a/packages/client/connection/src/client/api.ts b/packages/client/connection/src/client/api.ts index a773269257..a8e561ba33 100644 --- a/packages/client/connection/src/client/api.ts +++ b/packages/client/connection/src/client/api.ts @@ -12,7 +12,7 @@ export type { WorkspaceApi, WorkspaceId, WorkspaceView, CommandsApi, CommandDescriptor, SkillsApi, SkillEntry, ModelCatalogFailure, ModelCatalogModel, ModelProviderGroup, ModelReasoning, - ModelReasoningEffort, ModelRequestTelemetry, ModelTarget, SessionModels, SessionProjectionsBlock, + ModelReasoningEffort, ModelTarget, SessionModels, GoalsApi, GoalRef, } from '@deepseek-ai/dsh-host-apiproxy/api' export type { ToolCallView, ToolResultView } from '@deepseek-ai/dsh-tools/presentation' diff --git a/packages/client/connection/src/client/connection.ts b/packages/client/connection/src/client/connection.ts index 3e748cc68f..6eb6491e2f 100644 --- a/packages/client/connection/src/client/connection.ts +++ b/packages/client/connection/src/client/connection.ts @@ -35,6 +35,10 @@ function sleep(ms: number, signal: AbortSignal): Promise { }) } +/** Coarse connection state for the UI (audit C1): 'connected' after each generation's handshake, + * 'reconnecting' the moment the generation fails (covers the whole backoff+retry span). */ +export type ConnectionState = 'connected' | 'reconnecting' + /** Frame sink callbacks: the Controller owns the physical streams;

Contract: api-contracts v3 §8. ## Markdown rendering @@ -12,6 +12,10 @@ Pure React atoms (zero cordis): StateDot, ic_ds_* icons, Button/Pill/Menu/Modal/ `TerminalBlock` renders a shell command as a terminal surface: one prompt row per line of the command (the shortened `cwd` label on the first row only, since the view knows one working directory and a `cd` moves later lines elsewhere, then that line), the command's output, a status pill for a non-zero exit code or a terminating signal, and a copy control that writes the raw `output` prop. A run-state `StateDot` marks the call once, on the first row, out of flow in a gutter the card reserves as its own left padding, so the dot sits inside the card box yet left of the prompt text. It reaches three of `StateDot`'s states — the chase while `running`, red for the same exit status that renders the pill, green otherwise — so a card states whether its command is still running rather than leaving that to be inferred from the presence of output; it carries one visually hidden text label because `StateDot` is `aria-hidden`. One dot regardless of line count is deliberate: the exit status is the whole call's, so a dot per line would claim a per-line outcome the view does not carry. Command text is `white-space: pre`, so repeated spaces, tabs, and an indented continuation render verbatim while the row stays single-line and ellipsizes. ANSI escape sequences are parsed with the `anser` runtime dependency into React spans; cursor movements replay into a per-line column buffer before inert controls are stripped, since carriage return and backspace only MOVE the cursor: `100%` + CR + `OK` alone shows `OK0%`, while the `\x1b[K` a spinner writes with its redraw erases the tail so `100%\r\x1b[KOK` shows `OK`. Erase-in-line is honored in all three parameter forms, the cursor advances by terminal columns (8-column tab stops, two for emoji and CJK, none for a combining mark), and SGR state is normalized per cell as a terminal stores it, threading across lines and closing at the state the line ended in; basic-16 foreground colors map onto `--dsw-*` tokens, while 256-palette and truecolor values pass through as literal rgb. Output keeps `white-space: pre` with horizontal scrolling, so column-aligned output holds its alignment instead of soft-wrapping, and collapses to a head slice plus a tail slice past `maxLines` (default 16, the TUI transcript's split arithmetic) behind an expand button. Rationale: [the web terminal card note](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md). +## Diff rendering + +`DiffBlock` renders a file mutation as an inline diff surface: one bold path header per file, the removed lines (`- `, error token) above the added lines (`+ `, success token), a `⋯` gap before a same-file second hunk, and a dim `└ +A -R · N file(s)` footer. Lines are `white-space: pre` with horizontal scrolling, so a source line holds its indentation instead of soft-wrapping, and the body collapses to a head slice plus a tail slice past `maxLines` (default 16, `TerminalBlock`'s split arithmetic) behind an expand button. A create (`oldText: null`) has no removed side. The copy control writes the prefixed diff text (path headers, `- `/`+ ` lines, the gap) so a multi-file copy stays attributable, and floats in the top-right corner rather than on a banner row of its own. Geometry mirrors `CodeBlock`/`TerminalBlock`. The `+`/`-` block form mirrors the TUI transcript's diff card so a diff reads the same across front ends.

That makes alternate UIs, persistence backends, replay, and operational tooling consumers of one event stream instead of parallel sources of truth. - -## Extend the harness - -A swappable capability normally separates its interface, implementation, and consumer. Add or replace a provider behind a service such as `ctx.llm`, `ctx.fs`, `ctx.pty`, `ctx.web`, or `ctx.subagents`; register model-facing behavior through `ctx.tools`; attach policy and request shaping through typed events; compose the result in `cordis.yml` without forking the agent loop. - -Start with the [first-plugin guide](docs/user/develop/basic/index.md) and [extension cookbook](docs/cookbook/extension-cookbook.md). Use the [architecture](docs/architecture.md) for the system map, the generated [capability graph](docs/capability-seams.md) for current service relationships, and the [package map](packages/README.md) when you need ownership details. - -## Develop +For the recommended local interface, build the frontend after installation and after each update, then start the Web UI.

This repository ships both the composable SDK and `dsh`, a working agent assembled from the same packages.\n\n**Mission.** Build capable agent products without hard-wiring product choices into one loop. Models, tools, policy, storage, context, interfaces, and even the loop are [Cordis plugins](docs/architecture.md); the session log is the authoritative record from which model history, persistence, replay, queries, telemetry, and UIs derive.\n\n## Before you begin, thank you\n\nThank you for taking the time to try DeepSeek Harness.\n\nThis version is for internal testing only. Overall, it is still far from complete and nowhere near what we want to deliver. Some features are unfinished, and some parts will feel rough. What we learn from real use may also lead us to rethink the designs we have today.\n\nWe will keep working carefully on it, and we sincerely want direct feedback—especially about the moments when it fails, confuses you, or gets in your way. If it does not help you, or makes your work harder, please leave a message in our WeCom group and tell us plainly.\n\n> **Pre-release notice:** Package APIs, configuration, and persisted formats may change without compatibility shims until the first tagged release.\n\n## Start in one command\n\n```sh\ncurl -fsSL https://raw.githubusercontent.com/deepseek-harness/deepseek-harness/master/scripts/install.sh | sh\n```\n\nThe installer requires `git` and Node `^22.19 || >=24`, offers to install `pnpm`, prompts for a DeepSeek API key, and launches the TUI in the current directory. It keeps managed checkouts under `~/.dsh/source`; run the same command again to update. [`scripts/install.sh`](scripts/install.sh) documents alternate locations and non-interactive options.\n\n## Choose a surface\n\n| Surface | Entry point |\n|---|---|\n| Full-screen TUI | `dsh` |\n| Browser UI | `pnpm run demo:web` from a source checkout, or `dsh web` from a built checkout |\n| One-shot headless task | `pnpm run demo:headless \"summarize this workspace\"`, or `dsh -p \"summarize this workspace\"` from a built checkout |\n| ACP automation server | `pnpm run demo:acp` from a source checkout |\n| Python / JSON-RPC SDK | [`python/`](python/README.md) with its bundled runtime |\n\nThe one-line installer launches the source-running TUI without a build. The `dsh web` and `dsh -p` entries additionally need the frontend and client bundles from `pnpm run build`; `pnpm run demo:web` performs that build itself. The TUI, Web, and headless entries use the invoking directory as the workspace. See the [`dsh` CLI contract](apps/cli/README.md) for configuration, resume, provider, and workspace details; the [examples](examples/README.md) show the thinner ACP, JSON-RPC, Code Mode, and self-referential compositions.\n\n## What ships\n\nCapabilities are selected by composition. The repository's shipped plugins cover:\n\n- **Coding:** filesystem read/write/edit and search, shell and persistent PTY execution, LSP navigation, web search/fetch, reusable skills, and model-written Code Mode programs.\n- **Orchestration:** subagents, background tasks, worker-thread workflows, same-session goals, plan state, todos, and user questions.\n- **Operations:** workspace sandboxing and approvals, session persistence/resume/fork/query, compaction and spill, projections, titles, and OpenTelemetry export.\n\nAnything visible to the model must be reconstructable from the session log. That makes alternate UIs, persistence backends, replay, and operational tooling consumers of one event stream instead of parallel sources of truth.\n\n## Extend the harness\n\nA swappable capability normally separates its interface, implementation, and consumer. Add or replace a provider behind a service such as `ctx.llm`, `ctx.fs`, `ctx.pty`, `ctx.web`, or `ctx.subagents`; register model-facing behavior through `ctx.tools`; attach policy and request shaping through typed events; compose the result in `cordis.yml` without forking the agent loop.\n\nStart with the [first-plugin guide](docs/user/develop/basic/index.md) and [extension cookbook](docs/cookbook/extension-cookbook.md). Use the [architecture](docs/architecture.md) for the system map, the generated [capability graph](docs/capability-seams.md) for current service relationships, and the [package map](packages/README.md) when you need ownership details.\n\n## Develop\n\n```sh\npnpm install\npnpm run demo:tui\n```\n\nSet `DEEPSEEK_API_KEY` in the environment or root `.env`. The [development guide](docs/development.md) owns setup and validation; read the [architecture](docs/architecture.md) before changing `packages/`, and follow [AGENTS.md](AGENTS.md) when working in this repository.\n\n## Community\n\nFollow DeepSeek Harness on X for project updates.\n\n## License\n\n[BSD 3-Clause](LICENSE)\n" + "content": "# DeepSeek Harness\n\nEnglish | [中文](README.zh.md)\n\nDeepSeek Harness (`dsh`) is an open-source coding agent built on the DeepSeek Harness SDK.\n\nIt uses an architecture where **everything is a plugin**.\n\n## Before you begin, thank you\n\nThank you for making time to try DeepSeek Harness.\n\nThis version is still in internal testing. Some features remain unfinished, and parts of the experience may feel rough.\n\n“As one cuts and files, as one carves and polishes.” Products grow through repeated encounters with real use and candid feedback. The problems you uncover in practice may lead us to re-examine, or even discard, existing designs.\n\nWe especially want to hear about moments of failure, confusion, or friction. If DeepSeek Harness does not help—or instead makes your work harder—please leave a message in our WeCom group and tell us about your experience. Every report will help us refine it.\n\n## Install\n\nInstall `dsh` with one command:\n\n```sh\ncurl -fsSL https://raw.githubusercontent.com/deepseek-harness/deepseek-harness/master/scripts/install.sh | sh\n```\n\nThe installer requires `git` and Node `^22.19 || >=24`, offers to install `pnpm` when it is missing, and prompts for a DeepSeek API key.\n\nThe installer keeps every checkout under `~/.dsh/source`: the master clone at `~/.dsh/source/master` and each install's staging checkout as a git worktree `~/.dsh/source/staging-`. The stable symlink `~/.dsh/source/current` points at the active staging worktree, and `dsh` in `~/.local/bin` links to `current/bin/dsh`, so an upgrade repoints one symlink and the `dsh` on PATH never moves. Re-running the command adds a fresh staging worktree from an updated master and repoints `current` at it. See [`scripts/install.sh`](scripts/install.sh) for alternate install locations and other options.\n\n## Use DeepSeek Harness\n\n### Web UI\n\nFor the recommended local interface, build the frontend after installation and after each update, then start the Web UI. Resolve the running checkout from the `dsh` launcher so the command holds regardless of which staging worktree is current (the launcher resolves through the stable `current` symlink):\n\n```sh\ndsh_bin=$(cd \"$(dirname \"$(command -v dsh)\")\" && pwd -P)/$(basename \"$(command -v dsh)\")\nwhile [ -L \"$dsh_bin\" ]; do\n link=$(readlink \"$dsh_bin\")\n case $link in /*) dsh_bin=$link ;; *) dsh_bin=$(cd \"$(dirname \"$dsh_bin\")\" && cd \"$(dirname \"$link\")\" && pwd -P)/$(basename \"$link\") ;; esac\ndone\ndsh_dir=$(cd \"$(dirname \"$dsh_bin\")/..\" && pwd -P)\npnpm --dir \"$dsh_dir\" run build && pnpm --dir \"$dsh_dir\" run build:web\ndsh web\n```\n\nThe Web UI is served at `http://127.0.0.1:3080` by default.\n\n### TUI\n\nStart the full-screen terminal interface:\n\n```sh\ndsh\n```\n\n### Headless\n\nRun one task, print the final answer, and exit:\n\n```sh\ndsh -p \"summarize this workspace\"\n```\n\n### Automation and SDKs\n\nFrom a source checkout, start the ACP automation server:\n\n```sh\npnpm run demo:acp\n```\n\nThe [Python SDK](python/README.md) drives a bundled JSON-RPC runtime. The [examples](examples/README.md) cover the runnable TUI, headless, ACP, JSON-RPC, Code Mode, and self-referential compositions.\n\n## Why DeepSeek Harness\n\nBuilt-in capabilities cover file reading, editing, and search; shell and persistent PTY execution; reusable skills; task tracking, goals, plans, todos, and background tasks; subagents and workflows; sandboxing and approvals; persistent, resumable, forkable, and queryable sessions; LSP and web access; context compaction; and telemetry. Each composition selects the subset appropriate to its surface. The TUI also includes Plan Mode.\n\n- **Everything is a plugin.** Models, tools, policies, storage, context management, and interfaces are composable [Cordis plugins](docs/user/develop/basic/index.md), so deployments can extend or replace behavior without forking the agent loop. See the [architecture](docs/architecture.md) for the underlying design.\n- **Runs are reconstructable.** Anything visible to the model is logged in the authoritative session stream; persistence, resume/fork/query, replay, telemetry, and UIs derive from the same events. See the [session-log architecture](docs/architecture.md#session-log).\n- **Code Mode (opt-in).** It exposes a `run_code` tool and a generated TypeScript SDK; only program output re-enters model context.

A UI receiving that view saw one flattened text block: the line numbers were baked into the text as `N: ` prefixes, the file's language was unknown, and `totalLines` was gone. There was no way for a capable client to render a read the way it renders a diff — a line-numbered, syntax-highlighted code view with the line-number gutter separate from the content. + +The structured data cannot be recovered downstream. A tool result on the wire carries only the model-facing `ContentBlock[]` (the rendered text) plus an opaque `meta`; the canonical output object stays in the tool and never reaches the client or the session log. So a client that wants the line array, the total, and a language hint cannot parse them back out of the `N: text` text — the tool has to project them onto a channel that persists. + +## Decision + +Add a fourth `card` tag, `read`, to the [render-intent union](../architecture/2026-07-02-tool-render-intent-union.md) — result-side only. `ToolResultView` gains `ReadResultView { card: 'read'; title?; path; lines: ReadFileLine[]; totalLines; lang?; content? }`; `ReadFileLine { number; text }` is the shared line unit. `ToolCallView` is untouched: the pending state stays a `GenericCallView` (`kind: 'read'`) because a call carries no file content until `execute` returns, so there is nothing structured to show at call time. This diverges from the bash terminal card, which tags both sides — a terminal call already carries its command and cwd at call time, a read call carries neither content nor total, so tagging the call side would add an empty variant. + +The read tool projects the structured window through `output.presentationMeta`, the same persisted channel write/edit use for their applied-diff hunks ([canonical tool output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). `presentationMeta` runs once for a top-level surface call, returns `{ path, lines, totalLines, lang? }` as JSON the session validates and stores on the result's `meta`, and `presentResult` narrows that meta back into the `ReadResultView` on both live and replay paths. Without this channel the line array and total would be unreachable: the raw output object is not on the wire, and re-parsing the `N: text` text is lossy and fragile against the truncation footer. + +`presentResult` returns `undefined` — the generic fallback — whenever the meta is absent or malformed (`readMetaFromMeta` narrows it defensively, so a replay of an older logged result never throws), whenever the result is an error, and whenever the single text block is not the read envelope. On the success path it carries `content` (the envelope-stripped text) alongside the structured fields, so a UI without the read capability, including the current TUI, renders the file text through the generic/default card arm exactly as before. The TUI's `renderBody` switch (`packages/ui/tui/src/components/transcript.ts`) is not `assertNever`-exhaustive: `terminal` and `diff` have arms and everything else falls through to the generic arm, which reads `view.content` and the optional `title`. A `ReadResultView` satisfies that arm unchanged, so the TUI needs no new code and its output is unchanged. + +### Language hint derivation + +`langFromPath` (in `read-render.ts`) maps a file extension to a syntax-highlighting language id through a small fixed table (`LANG_BY_EXTENSION`) covering common source, config, and markup extensions. It reads the extension after the last path segment and last dot, is case-insensitive, and returns `undefined` for a dotfile (`.gitignore`), an extensionless name (`/etc/hosts`), a trailing dot, and any unknown extension — the card then omits `lang` and a UI renders plain text. The table is not a tunable: it is a display hint a UI may ignore, not a deployment-varying choice, and an unknown extension degrades to plain text rather than failing. It is deliberately small rather than an exhaustive language registry; extending it is a one-line table addition. + +## Alternatives considered + +**Re-parse the `N: text` model-facing text in `presentResult`.** Rejected: the structured line array would have to be reconstructed by splitting each line on the first `: `, which is ambiguous (a line whose own text contains `: `), loses the exact `totalLines` (the footer only states it in some branches), and breaks the moment the render format changes. `presentationMeta` carries the already-structured data with no re-parse. + +**Tag the call side too (`ReadCallView`), mirroring the terminal card's both-sides symmetry.** Rejected: a read call has no content, no line array, and no total until it executes — a call-side read card would be an empty variant duplicating what `GenericCallView` (`kind: 'read'`, follow-along location) already expresses. The terminal card tags both sides because a terminal call genuinely carries call-time data (command, cwd); a read call does not. + +**Put the structured window in a new service or a side channel instead of `meta`.** Rejected: `meta` is the established persisted presentation channel (write/edit's applied diffs ride it), it replays for free with the session log, and it needs no new plumbing. A service would reinvent persistence and replay that the event log already provides. + +**A merge-extensible union instead of a closed tag.** Rejected for the same reason the [render-intent union](../architecture/2026-07-02-tool-render-intent-union.md) closed: a new card needs consuming code to render it, so a variant a consumer silently drops is worse than a compile error. Adding `read` to the closed union is the sanctioned way to extend it — each consumer that switches on `card` keeps compiling because the new member falls through its generic default, and a consumer that wants the rich view adds its own arm. + +## Consequences + +`ToolResultView` has a fourth member. Every consumer that switches on `card` keeps compiling: the TUI and the current Web client route an unknown card to their generic path, and the read card carries `content` so that path shows the file text. The Web frontend that renders the line-numbered, syntax-highlighted view from `lines`/`lang`/`totalLines` is a separate follow-up PR; this PR is the backend that makes the data reachable. Until that lands, a read renders exactly as it did before (the generic text card) everywhere. + +The read tool now computes `presentationMeta` for every top-level read, a small per-call projection (a `lines.map` and one `langFromPath` call) on data already in hand. The meta is persisted with the session log, so a read result is slightly larger on disk — the line array it already rendered as text, now also structured. + +## Testing + +`packages/fs/tool-fs/tests/read-render.spec.ts` unit-tests `langFromPath` (known extensions case-insensitively, extension read after the last segment and last dot, and the `undefined` cases: dotfile, extensionless, trailing dot, unknown) and `readMetaFromMeta` (a well-formed narrow with and without `lang`, and every rejection: non-object, array, missing or wrong-typed `path`/`totalLines`/`lines`, a malformed line entry, and a non-string `lang`). `packages/fs/tool-fs/tests/tools.spec.ts` pins the tool wiring: `execute` attaches the structured window (with and without a `lang` hint) as `meta`, `presentResult` narrows it into a `card: 'read'` view carrying the envelope-stripped `content`, and the decline paths (error result, non-single-text content, malformed envelope with valid meta, and valid envelope with absent or malformed meta) all fall back to `undefined`. Both changed source files hold per-file 100% coverage.

the structured matches/paths never reached the client. Add a card:'search' result view with a kind discriminant ('matches' grouped by file for grep, 'paths' for glob), projected through each tool's output.presentationMeta and read back in presentResult. The projections re-apply the same inline cap and per-line budget as the render text and report total + truncated, so a UI never presents a capped page as complete. A UI without the search card falls back to content; the TUI is unchanged.

A web frontend that wants to render a search result as an expandable per-file group of matches, or as a selectable path list, had to re-parse that text. Both tools already declared a call-time [render intent](../architecture/2026-07-02-tool-render-intent-union.md) (`GenericCallView`, `kind: 'search'`) but no result-time view, so the completed call fell back to the generic card that renders the raw text. + +The structured canonical value does not cross the wire: only the model-facing render text and, when a tool declares `output.presentationMeta`, a JSON metadata payload reach the client, threaded through the `tool/result` event ([canonical-output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). A result-time view carrying structured data therefore has to project that data into `presentationMeta` and read it back in `presentResult` — the same path `write`/`edit` use for their diff cards. + +## Decision + +`packages/core/tools/src/presentation.ts` adds `card: 'search'` to the `ToolResultView` union as `SearchResultView`, a `kind`-discriminated view that expresses both tools' shapes: `SearchMatchesResultView` (`kind: 'matches'`) carries `grep`'s matches grouped by file as `files: { path, matches: { lineNumber, line }[] }[]`, and `SearchPathsResultView` (`kind: 'paths'`) carries `glob`'s flat `paths: string[]`. Both carry `truncated: boolean` and `total: number`, and an optional `content?: ContentBlock[]`. + +One view with two shapes rather than two cards, because both tools are the same visual object — a search result — and a web consumer switches on one `card` value, then on `kind` for the row shape. The discriminated `kind` keeps each shape's fields non-optional (a matches view always has `files`, a paths view always has `paths`) instead of a single interface where every shape-specific field is optional. + +The card tag is result-time only. A search call stays a `GenericCallView` (`kind: 'search'`): the pending state has no matches or paths to show, so there is nothing a `SearchCallView` would carry that the generic title does not. This is the asymmetry with the terminal card, whose call view carries the command, cwd, and description that exist before execution; a search's structured content exists only after `execute`. + +`packages/fs/tool-fs-search/src/presentation.ts` owns the projection and the narrowing. `grepSearchMeta`/`globSearchMeta` project the canonical value into a `SearchMeta` payload each tool declares as `output.presentationMeta`; `presentGrepResult`/`presentGlobResult` read `result.meta` back through `searchViewFromMeta` and attach the model-facing `result.content` as the view's `content`. The projections apply the SAME inline cap and per-line preview budget the model-facing render applies, and report `total` as every result the search found (before capping) with `truncated` set when the cap dropped results. This is the truncation-honesty point: the model saw a capped inline result plus a spill footer, so the card must not present the retained page as the complete result — a UI reads `truncated`/`total` to show a capped indicator rather than claiming completeness the model never had. + +`searchViewFromMeta` narrows the opaque `meta` defensively and returns `undefined` on any malformed or absent payload, exactly as `diffsFromMeta` does, so a presenter run on an older or hand-edited replayed log falls back to the generic card instead of throwing. `presentResult` returns `undefined` for a failed result, for absent meta (a nested `run_code` dispatch computes no `presentationMeta`), and for the other tool's meta shape (each presenter narrows to its own `kind`). + +The `SearchMeta` member shapes are object-literal `type` aliases, not the `SearchFileMatches`/`SearchLineMatch` interfaces the view exposes. Only a type alias is assignable to the `JsonValue` index signature `presentationMeta` returns; the two are structurally identical, so the projected value still reads back as a `SearchResultView`. + +The TUI (`packages/ui/tui/src/components/transcript.ts`) needs no dedicated arm: its result-view switch handles `terminal` and `diff` explicitly and falls through to a generic arm that renders `view.content ?? this.result?.content`. Because `SearchResultView` carries the model-facing text as `content`, the TUI renders it as the same text it already showed. The web frontend that renders the structured `files`/`paths` shape is a separate later PR; this PR is the backend contract and its two producers. + +## Alternatives considered + +**A single flat `SearchResultView` interface with optional `files?` and `paths?`.** Rejected: it makes both shape-specific fields optional on every value and lets a malformed view carry both or neither. The `kind` discriminant keeps each shape's fields required and lets a consumer switch exhaustively. + +**A call-time `SearchCallView` mirroring the terminal card's both-sides symmetry.** Rejected: a search call has no matches or paths before `execute`, so the view would carry only the title the `GenericCallView` already carries. The terminal card's call view earns its tag because a command, cwd, and description exist at call time; a search's structured content does not. + +**Carry the structured result in a bespoke channel instead of `presentationMeta`.** Rejected: the canonical value is execution-local and never reaches the client, and `presentationMeta` is the established seam that persists a tool's JSON presentation payload with `tool/result` and threads it back to `presentResult`. Adding a second channel would duplicate that path. + +## Consequences + +`grep` and `glob` now compute `presentationMeta` on every non-nested successful call, a bounded projection over the already-parsed matches or paths. The projection re-applies the retention cap the render already applied, so the retained set is computed twice per call; the input is bounded by the raw-output cap, so this is not a new scaling concern. + +A UI without a search card renders the attached `content` text, so no consumer regresses. The web consumer that renders the structured shape reads `truncated`/`total` and the per-file groups; because the view carries only the retained page, a UI wanting the complete result follows the spill locator in the model-facing text, exactly as the model does. + +## Testing + +`packages/fs/tool-fs-search/tests/presentation.spec.ts` pins the pure layer: `groupMatchesByFile`'s first-seen file order, `grepSearchMeta`/`globSearchMeta` projection with the cap applied and `total` reporting the pre-cap count, the per-line preview budget on a projected match line, and `searchViewFromMeta`'s narrowing of both good shapes plus every malformed case (non-object/array meta, missing or mistyped `truncated`/`total`, unknown `kind`, malformed `files` entries, non-string `paths`). `packages/fs/tool-fs-search/tests/tools.spec.ts` pins the wiring through the real tool registry: a capped `grep`/`glob` execute produces the `SearchMeta` on `result.meta` and `presentResult` builds the search view with `content` attached, a nested `run_code` dispatch computes no meta so `presentResult` falls back, and a failed or cross-shape or malformed result falls back to the generic card.

Operations: `prompt`/`cancel` (RPC passthrough; failures land in the snapshot's `promptError`), `open` (pull the tail history page, idempotent), `loadOlder` (upward paging, reentry-guarded), `resync` (reconnect = clear the window and rerun open). Subscription: `subscribe`/`getSnapshot` (always the cached reference) — `implements ObservableSnapshot`, with `useSelector = bindSnapshotSelector(this)` attached at construction, so a Session is directly a uSES source. Frame dispatch is one switch: `session/event` frames dedup by seq (the only dedup key), buffer while open is in flight, otherwise append + incremental projection; open/stitch merges the live buffer by seq and backfills once if `subscribed.lastSeq` outruns the window tail. -- **ConversationSnapshot** (conversation.ts): the immutable snapshot contract — `nodes` (the human transcript, log-ordered), `partial`, `runningCalls`, `pending`, `running`, `removed`, `openState`, `hasMore`, `promptError` and kin. **Reference discipline** (the premise of memo and uSES): the top-level object is fresh on every change; the nodes array is rebuilt but element references come from the cache; unchanged substructures reuse the previous snapshot's references. +- **ConversationSnapshot** (conversation.ts): the immutable snapshot contract — `nodes` (the human transcript, log-ordered), `partial`, `runningCalls`, `pending`, `running`, `removed`, `openState`, `hasMore`, `promptError` and kin. **Reference discipline** (the premise of memo and uSES): the top-level object is fresh on every change; an unchanged nodes projection keeps the same array reference, while a changed flow returns a new array that reuses unchanged element references; unchanged substructures reuse the previous snapshot's references. - **SessionManager** (manager.ts): instance cluster + frame entry + the session list. sessionId-bearing frames go only to existing instances (a mux broadcast must not instantiate every session); approval/question `requested` frames are the exception — they never land in history, so they buffer in `pendingBuffers` and replay on instantiation. - **Notifier** (notifier.ts): two channels chosen by change source. `markDirty()` (default; frame-driven changes always) batches per microtask — N changes, one notification, one re-render; the flush rebuilds the snapshot cache before notifying. `notifyNow()` (only direct echoes of user gestures) rebuilds and notifies in the same tick — controlled inputs roll the DOM back and jump the caret if their echo defers to a microtask. Frame-driven code using notifyNow collapses batching back to per-frame renders; banned. - **TranscriptAdapter / PartialAccumulator**: the transcript is the append-origin surface projected in log order (`isAppendSurfaceEvent` from `@deepseek-ai/dsh-session/surface`) plus one marker per landed compaction checkpoint — never the model surface, which shadows replaced ranges and would erase conversation the reader already saw. Node order is seq-monotonic by construction, so there is no core `seq === index` assertion to satisfy and no degradation branch. Chunks contribute no node (O(1) skip): the accumulator folds StreamChunks into `AssistantBlock[]`, a delta swapping only that block's reference, and the finalizing message discards the accumulator in the same batch (no flicker on promotion). Cost model: one chunk = one string concatenation + a dirty mark; an unsubscribed Session under a frame storm costs only the mark. diff --git a/.agents/notes/implemented/architecture/2026-07-19-gui-web-client-architecture.zh.md b/.agents/notes/implemented/architecture/2026-07-19-gui-web-client-architecture.zh.md index 560015191f..2d57c12eba 100644 --- a/.agents/notes/implemented/architecture/2026-07-19-gui-web-client-architecture.zh.md +++ b/.agents/notes/implemented/architecture/2026-07-19-gui-web-client-architecture.zh.md @@ -68,8 +68,8 @@ Session.handleMuxEnvelope ──► events 窗口（seq 连续升序） Notifier 微任务合批 ──► ConversationSnapshot 缓存 ──uSES──► 组件 ``` -- **Session**（session.ts）：懒建、常驻——建成后在后台持续吃帧，切走切回秒显。操作面：`prompt`/`cancel`（RPC 透传；失败落进快照的 `promptError`）、`open`（拉尾页 history，幂等）、`loadOlder`（向上翻页，防重入）、`resync`（重连 = 清窗口重跑 open）。订阅面：`subscribe`/`getSnapshot`（恒返缓存引用）——`implements ObservableSnapshot`，构造时挂 `useSelector = bindSnapshotSelector(this)`，Session 本身就是 uSES 源。帧分发是一个 switch：`session/event` 帧按 seq 去重（唯一去重键），open 在途时缓冲，否则追加 + 增量 fold；open/缝合按 seq 合并 live 缓冲并去重，`subscribed.lastSeq` 超出窗口尾则回补一次。 -- **ConversationSnapshot**（conversation.ts）：不可变快照契约——`nodes`（人类对话记录，日志序）、`partial`、`runningCalls`、`pending`、`running`、`removed`、`openState`、`hasMore`、`promptError` 等。**引用纪律**（memo 与 uSES 的前提）：顶层对象每变必新；nodes 数组重建但元素引用来自缓存；未变的子结构复用上一快照的引用。 +- **Session**（session.ts）：懒建、常驻——建成后在后台持续吃帧，切走切回秒显。操作面：`prompt`/`cancel`（RPC 透传；失败落进快照的 `promptError`）、`open`（拉尾页 history，幂等）、`loadOlder`（向上翻页，防重入）、`resync`（重连 = 清窗口重跑 open）。订阅面：`subscribe`/`getSnapshot`（恒返缓存引用）——`implements ObservableSnapshot`，构造时挂 `useSelector = bindSnapshotSelector(this)`，Session 本身就是 uSES 源。帧分发是一个 switch：`session/event` 帧按 seq 去重（唯一去重键），open 在途时缓冲，否则追加 + 增量投影；open/缝合按 seq 合并 live 缓冲并去重，`subscribed.lastSeq` 超出窗口尾则回补一次。 +- **ConversationSnapshot**（conversation.ts）：不可变快照契约——`nodes`（人类对话记录，日志序）、`partial`、`runningCalls`、`pending`、`running`、`removed`、`openState`、`hasMore`、`promptError` 等。**引用纪律**（memo 与 uSES 的前提）：顶层对象每变必新；未变化的 nodes 投影保持同一数组引用，消息流变化时返回新数组并复用未变化的元素引用；未变的子结构复用上一快照的引用。 - **SessionManager**（manager.ts）：实例簇 + 帧总入口 + 会话列表。带 sessionId 的帧只投已存在实例（mux 广播不得把每个会话都实例化）；例外是审批/问答 `requested` 帧——它们不落 history、open 无法回补，故缓冲进 `pendingBuffers`，实例化时回放。 - **Notifier**（notifier.ts）：两条通知通道，按变更来源取用。`markDirty()`（默认；帧驱动一律用它）按微任务合批——N 次变更、一次通知、一次重渲染；flush 先重建快照缓存再通知。`notifyNow()`（仅用户手势的直接回响）同 tick 重建并通知——受控输入的回响若延到微任务，DOM 会回滚、光标跳尾。帧驱动代码用 notifyNow 会让合批塌回逐帧渲染；禁。 - **TranscriptAdapter / PartialAccumulator**：对话记录是按日志顺序投影的 append 来源 surface（`@deepseek-ai/dsh-session/surface` 的 `isAppendSurfaceEvent`），外加每次落地的压缩检查点一个标记——绝不用模型 surface，后者遮蔽被替换的范围，会抹掉读者已经看过的对话。节点顺序天然按 seq 单调，因此既无核心 `seq === index` 断言需要满足，也没有降级分支。分片不贡献任何节点（O(1) 跳过）：累积器把 StreamChunk 折叠成 `AssistantBlock[]`，一次增量只换该块引用；定稿消息到达即在同一批内弃掉累积器（提升无闪烁）。成本模型：一个分片 = 一次字符串拼接 + 一个脏标记；帧风暴下未订阅的 Session 只花那个标记。 diff --git a/.agents/notes/implemented/process/2026-07-20-gui-testing-system.i18n.yaml b/.agents/notes/implemented/process/2026-07-20-gui-testing-system.i18n.yaml index 05d448c79b..deafb47f70 100644 --- a/.agents/notes/implemented/process/2026-07-20-gui-testing-system.i18n.yaml +++ b/.agents/notes/implemented/process/2026-07-20-gui-testing-system.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

A landed compaction therefore keeps the conversation it shadowed on the model side: the marker reports where the model stopped seeing that history instead of erasing it. Model-only replacement copies stay out: a pruned `tool/result` and a regenerated `assistant/message` rewrite one node for the model and mark no boundary. A checkpoint is a `user/message` carrying the compaction seam's plugin source that **replaced** a surface range; an appending plugin-sourced `user/message` is injected context, not a compaction. The adapter's plugin literal is pinned to the seam's own declaration by a type-only import of the cordis-free [`dsh-compact/checkpoint`](../../compact/compact/README.md) leaf, so renaming it there fails `tsc` here; a **value** import of the package would fail the client purity gate, and the package **root** is unreachable even as a type (it reaches `dsh-session`'s root, whose `Context` merge collides the host `sessions` with this program's). `tests/compact-checkpoint-pin.spec.ts` covers the same drift behaviorally. -Because the projection is log-ordered, the node array is seq-monotonic by construction: log-only `command/run` / `command/done` nodes splice in by seq, `Session` merges interrupted frozen nodes by their fractional seqs, and a window whose checkpoint cites a shadowed range outside it renders the marker with nothing logged. The marker's summary text comes from the checkpoint's `compact/summary` provenance; a window cut that left the provenance outside makes the row non-expandable rather than empty, and a later page that supplies it resolves the text.

It is skipped when provider, model, and capacity all match the previous record. A route whose adapter advertises no capacity is recorded with `contextWindow` absent, clearing an older route's denominator. Capacity deliberately stays out of `EpochHeader`. That type is the reconstruction contract — what a request was built from — and `headerEquals` compares it field-wise to decide whether a snapshot is a real `change`. Capacity is adapter metadata describing a route, so placing it there would let a capacity change masquerade as a request-envelope change and would drag it into the loop's reconstruction invariant.

That view already reaches the browser — host, connection, and runtime deliver it onto `ConversationSnapshot` as `resultView` — but the Web client ignored it: every non-terminal, non-diff tool result fell through to the generic card, which renders the model-facing text. A web frontend that wants an expandable per-file group of matches, or a scannable path list, had only the pre-formatted text. + +This is the follow-up the search render card note names: that PR was the backend contract and its two producers; this PR is the web consumer. + +## Decision + +`SearchBlock` is a `ui-primitives` component that renders a completed search as either shape, and the Web render sites for a `grep`/`glob` call consume the search render intent through it. `ui-conversation/src/client/contract/search-card-model.ts` is the single place that turns the snapshot's `resultView` into the component's props, so no render site re-derives the shape. It returns null — the generic path — whenever the result view is not a search card, including a still-running call (a search card is result-time only, so there is nothing before `execute`), a generic result a `grep`/`glob` failure or a nested `run_code` dispatch produces, a terminal result view, and a `card` value this client version does not know. + +The asymmetry with the terminal card is deliberate and inherited from the backend contract: `terminalCardModel` reads both `callView` and `resultView` because a command, cwd, and description exist at call time; `searchCardModel` reads only `resultView` because a search's matches or paths exist only after execution. A running search row therefore shows its summary alone, with no card. + +One component draws both shapes, discriminated by `kind`, because `grep` and `glob` are the same visual object — a search result. `SearchMatchesBlockProps` (`kind: 'matches'`) and `SearchPathsBlockProps` (`kind: 'paths'`) keep each shape's fields required rather than a single interface with everything optional. The component flattens whichever shape it holds into one list of render rows — a file header row plus its match rows for the matches shape, one path row per path for the paths shape — so the height cap counts a file header as one row exactly as a match line or a path, and the head/tail slice arithmetic is `TerminalBlock`'s (`ceil(max/2)` head, the remainder tail), so a long search result and a long command output cut at the same place across the two cards. + +The component's contract: + +- **Grouped matches, collapsible per file.** Each file is a header row (a bold path plus its match count, the whole row the collapse control) followed by its `lineNumber: line` rows. Collapsing a group drops its match rows from the flattened list and from the height cap's arithmetic, but never from the copy text. +- **Flat path list.** The paths shape renders one path per row, no headers. +- **A capped indicator.** When `truncated`, a pill reads `已截断 · 共 {total}` beside the banner summary, so the card never presents a capped page as the complete result — a reader who wants the rest follows the spill locator in the model-facing text, exactly as the model does. The banner summary is a plain structural count (`{n} 处匹配 · {m} 个文件`, or `{n} 个路径`). +- **No soft wrapping.** Result rows are `white-space: pre` inside a horizontally scrolling box, so a long match line or a deep path scrolls sideways rather than folding. +- **Height cap with an expand control.** More than `DEFAULT_SEARCH_MAX_LINES` (16) rows shows a head/tail slice with a button reporting the hidden count, the same shape and arithmetic as `TerminalBlock`. +- **Copy.** The copy control writes the whole structured result — every file and match, or every path — regardless of the height cap or which groups are collapsed, so the clipboard carries the result rather than what the card happens to be showing. + +Geometry, radius, and fonts mirror `CodeBlock` and `TerminalBlock`, so a search card reads as one family with them; `white-space: pre` plus horizontal scroll is the shared deliberate divergence. + +### Render sites + +Three sites consume the derivation, mirroring the terminal card's placement exactly: + +- **The keyed `SearchRow`** (`toolviews/search-sample.tsx`) registers ONE component under both `grep` and `glob` in the `conversation.chat.toolview` keyed hole, and renders the card RESIDENT under the summary row, capped at `CHAT_SEARCH_MAX_LINES` (8) — the same posture `BashRow` takes for its terminal card. Both tool names get the same row because the derived `kind` decides the shape, so a second component would duplicate it. (This resident posture matches the current terminal/diff cards; a separate later PR unifies the whole-row collapse/expand interaction and flips all resident cards at once — out of scope here.) +- **The generic fallback** (`chat/GenericToolCard` → `chat/ToolRow`) threads the derived model as an expand-gated body, the same arm `terminal` uses: a `grep`/`glob` result with no keyed row (none in the shipped app, since both are registered) still renders its card behind the row's expand toggle. +- **The details panel** (`skeleton/DetailsPanel`) renders the card at the primitive's own full height in the Output section, keeping the JSON Input section. + +`CHAT_SEARCH_MAX_LINES` (8) is the row cap, half the primitive's default the panel keeps, for the same reason as `CHAT_TERMINAL_MAX_LINES`: the chat flow is a summary surface read across many calls, the panel is the single-call reading surface. + +## Alternatives considered + +**Two card components, one per tool.** Rejected: `grep` and `glob` are the same visual object discriminated only by `kind`, so two components would duplicate the banner, the height cap, the copy control, and the no-wrap geometry. One component switching on `kind` is what the backend's single `card: 'search'` view is for. + +**A `SearchCallView` so the row renders a card while the search runs.** Rejected: the backend contract deliberately has no call-time search view — a search has no matches or paths before `execute`. The running row shows its summary alone, and `searchCardModel` returns null for a running block, which is faithful to what exists. + +**Reuse `TerminalBlock` or `CodeBlock`.** Rejected: neither models per-file collapsible groups or a truncation pill, and both would need the grouped-matches shape bolted on. The three blocks share their geometry and font tokens instead, which is the only part where one implementation is correct for all. + +## Consequences + +`SearchBlock` reads only the search 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. A UI without the search capability still gets the bridge's fenced fallback; nothing about the tool's result shape changed. Extending `ToolRow` with a `search` body prop adds one arm beside `terminal`; a call carries at most one card kind, so the two are never both present on a row. + +## Testing + +`packages/client/ui-primitives/tests/search-block.spec.tsx` pins the component at per-file 100%: both kinds, the truncation pill with its pre-cap total, the empty arm, per-file collapse/re-expand without touching neighbours, a file header counting as one capped row alongside its matches, the head/tail cap and its expand control across both shapes and the no-tail and default-cap edges, and the copy control writing the whole structured result on the accepted and refused clipboard paths. + +`packages/client/ui-conversation/tests/search-card.spec.tsx` pins the wiring at every render site: `searchCardModel`'s derivation for both kinds, the truncation signal, the replacement title, and each null arm (running, no views, generic, terminal, unknown card); the chat row's expand-gated matches and paths bodies through `GenericToolCard` against the non-search args-JSON body; `SearchRow`'s resident card for both kinds, its agreement with the summary row's run state, the replacement-title precedence, and the keyed registration under both `grep` and `glob` with one component; and the details panel's Output section for both kinds against the non-search flattened form. `packages/client/ui-conversation/src/*` sits on the coverage exclude list, so this file is written against no gate pressure. `packages/client/connection/src/client/fixture.ts` gains a `grep` turn

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), and for a generic result view (a web tool's error path returns the generic card, whose text the generic path preserves). + +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 same allowlist MarkdownText applies to untrusted assistant-authored links.** 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:` 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. + +## 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 matches MarkdownText's, so untrusted 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); 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 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.

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）、以及对 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）。 + +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 链接所用的同一 allowlist。** 一个 source 或 fetch URL 仅当其协议为 `http:` 或 `https:`

卡片,匹配契约的 result-only web 形状,且以真实工具命名,使其命中键控 `WebRow`。它们被排在 todo turn（重编号为 68）之前,理由与终端 turn 相同:待定计划在下一个 `turn/start` 退休,所以排在其后的 turn 会清空 dock 的 plan strip。这驱动 built-boot snapshot 与一个实时 `?fixture` 服务。 +

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr. Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under  mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. */\n  bash: {\n    /** The bash command to execute. */\n    command: string;\n    /** Clear, concise description of what this command does in active voice, 5-10 words (shown in the UI).

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

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

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

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

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

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

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.

Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work).

An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.

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

 {"type":"request/header","seq":4,"time":1783957884486,"data":{"header":{"config":{"provider":"deepseek","model":"deepseek-v4-flash"},"system":"You are an AI agent powered by the DeepSeek Harness SDK.\n\nYou are headless-agent, a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

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

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

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

A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Track every terminal session id and close sessions that no longer matter. An inferred_idle or timeout result does not prove the foreground command exited.\n\nTrack every background task id you start.

For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution.

Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

From 8c5c4b46c83562611eb4bf3fe9adf60fdc35c81b Mon Sep 17 00:00:00 2001
From: Chinesezjc 
Date: Thu, 30 Jul 2026 18:32:55 +0800
Subject: [PATCH 058/278] =?UTF-8?q?fix(web):=20address=20diff=20card=20rev?=
 =?UTF-8?q?iew=20=E2=80=94=20split=20terminator,=20error=20arm,=20wire=20n?=
 =?UTF-8?q?arrowing?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- DiffBlock: an empty side contributes zero lines and a trailing newline is a
  terminator, so a create ending in a newline draws one added line (not a
  phantom empty one) and a full deletion draws no phantom + line.
- diffCardModel: narrow the wire diffs payload (card is the only validated
  field) so a malformed diff card falls back to the generic path instead of
  throwing inside DiffBlock.
- FileMutationRow: surface the result text when an errored mutation has no diff
  card, so a failed edit/write is more than a red dot.
- copyText ends its closed union on assertNever.
- Docs: drop the "bridge relativizes" claim, record the file-count divergence
  from the TUI footer, correct the built-boot overclaim, note why the row title
  outranks the view title, and make fixture turn 67 args self-consistent.
- Tests: terminator/empty-side/interior-blank rows, wire-narrowing null arms,
  the error-text arm and its name/code fallback, stopped state, no-path summary,
  and the registration/disposal shape.

 `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, with one deliberate divergence noted below (the file count):
 
-- **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.
+- **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 — the divergence from the TUI, whose footer uses `diffs.length` and so reads two hunks in one file as `2 files` where this reads `1 file`.
 - **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.
 - **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.

+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.

 `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。

 - **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。

Subject: [PATCH 059/278] test(snapshot): re-record ACP/TUI goldens for the
 read card meta

The read tool now projects presentationMeta ({path, lines, totalLines}) onto
its tool/result, so every scenario with a read call carries that meta; the
cordis-inspect snapshot's embedded type surface gains ReadResultView /
ReadFileLine / the widened ToolResultView. Model-facing text is unchanged.
Refreshed keyless via test:snapshot:refresh. The unrelated goal.snapshot
SQLite ExperimentalWarning failure is pre-existing on clean master.

Subject: [PATCH 060/278] fix(tui): keep read result on the dim-Markdown body
 path

A read result now carries card:'read', but render()'s genericContent gate was
card==='generic' only, so the read body kept its text yet lost the dim-Markdown
dimBody treatment the generic card gave it. Admit card:'read' to that gate so
its content fallback takes the same dim path, restoring read's TUI rendering to
what it was before the read card existed. Refresh the parallel-file-reads TUI
golden accordingly and correct the Note's TUI claim on both language sides.

 The read tool projects the structured window through `output.presentationMeta`, the same persisted channel write/edit use for their applied-diff hunks ([canonical tool output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). `presentationMeta` runs once for a top-level surface call, returns `{ path, lines, totalLines, lang? }` as JSON the session validates and stores on the result's `meta`, and `presentResult` narrows that meta back into the `ReadResultView` on both live and replay paths. Without this channel the line array and total would be unreachable: the raw output object is not on the wire, and re-parsing the `N: text` text is lossy and fragile against the truncation footer.
 
-`presentResult` returns `undefined` — the generic fallback — whenever the meta is absent or malformed (`readMetaFromMeta` narrows it defensively, so a replay of an older logged result never throws), whenever the result is an error, and whenever the single text block is not the read envelope. On the success path it carries `content` (the envelope-stripped text) alongside the structured fields, so a UI without the read capability, including the current TUI, renders the file text through the generic/default card arm exactly as before. The TUI's `renderBody` switch (`packages/ui/tui/src/components/transcript.ts`) is not `assertNever`-exhaustive: `terminal` and `diff` have arms and everything else falls through to the generic arm, which reads `view.content` and the optional `title`. A `ReadResultView` satisfies that arm unchanged, so the TUI needs no new code and its output is unchanged.

That default arm alone was not enough: `render()` sets `genericContent` — and with it the dim-Markdown `dimBody` treatment — on a separate gate that was `card === 'generic'` only, so a `read` card would have kept the text but lost its dim styling. The gate now admits `card: 'read'` too, taking `content` down the same dim-Markdown path, so a read renders in the TUI exactly as it did before the read card existed. Beyond that one gate the TUI needs no read-specific code.

Revisit only if `allow_always` grant storage ever needs machine-checkable scopes.
 - **A generic `env/state` facts map with an owner service** — rejected: approval and sandbox compose independently, so neither's state may drag in a third package; single-key folds are one `findLast` each, dissolving the owner service; no invariant spans the knobs, so atomic multi-key patches bought nothing.

 - **The approval narrator's restart baseline parses prompt prose.** The closed candidate sentence is owned by the writing module itself, so a wording change is a coordinated writer+parser edit in one file; a session whose headers predate the section silently adopts the current policy without a notice.

@@ -12,11 +12,13 @@ The sandbox policy already enforced and logged each session's file-effect mode,
 
 `dsh-sandbox-policy`, the owner of mode and workspace-root resolution, registers one `sandbox:policy` system-prompt section. Every agent request resolves the active session directly through `ctx.sandboxPolicy.resolve({ session })`; there is no denial-history scan, delta narrator, or in-memory “last told” state.
 
-The section states the current file-effect mode and only its owned consequences. `read-only` says ordinary writes, edits, and file-mutating shell effects are denied while required sinks may remain writable. `workspace-write` lists the canonical writable roots returned by the shared `writableRoots()` policy: the immutable session workspace root, `/tmp`, and the platform temporary directory, deduplicated after canonicalization. `danger-full-access` says the DSH file sandbox adds no file restriction. Every form says host permissions or backend availability may restrict more and that network and process access are outside this policy.
+Enforcing backends register independently disposable `filesystem`, `bash`, or `terminal` family contributions with the policy owner. The section names only registered families in canonical order, and is empty without one. This is current need, not a future extension: the shipped headless inheritance composition combines sandboxed filesystem tools with unfenced one-shot bash, while the persistent-tools composition combines sandboxed filesystem tools and terminal commands without a sandboxed one-shot bash executor. A blanket statement would be false in both.
+
+The section states only facts shared by every enforcement dialect for each registered family. `read-only` says those operations cannot modify files. `workspace-write` states the canonical session workspace with non-exclusive wording and summarizes, without enumerating, that some platform temporary areas may also be writable. `danger-full-access` says the DSH file sandbox does not restrict those operations. Backend-selected temporary paths, `/dev/null`, runner readiness, and other policy domains are absent because `resolve()` cannot establish them at request assembly.
 
 The provider runs during normal request assembly, after a `/permission` switch has committed its existing `sandbox/mode` event and before `request/header` is logged. The rendered system text is therefore the durable reconstruction of the exact model-visible fact. Repeated assemblies over unchanged session state produce identical bytes; resume and replay fold the same durable mode event and immutable `SessionHeader.cwd` without catch-up state.
 
-Ownership stays narrow. Approval policy remains the separate `approval:policy` section, plan mode remains `plan:policy`, and tool plugins continue to own schemas and operation guidance. The prompt states policy; bash and filesystem backends remain the enforcement boundaries.

 **Repeat tool schemas or approval and plan guidance in the section.** Rejected because those surfaces already have owners and independent lifecycles. Duplicating them would create contradictory request prefixes and broaden invalidation.
 
-**Keep sandbox mode absent because a standing mode label once caused preemptive refusal.** Rejected by the later Web evidence and the completed cross-family policy. The earlier sentence named only a bash sandbox and did not explain the actual write/edit boundary, so it could conflict with visible tools and escalation guidance. The owner-derived section states the complete current file-effect consequence, canonical workspace scope, and explicit non-guarantees without duplicating tool instructions. This supersedes only the absence decision in the [sandbox Agent Note](2026-07-06-sandbox.md); its enforcement and escalation boundaries remain current.
+**Keep sandbox mode absent because a standing mode label once caused preemptive refusal.** Rejected because a fresh Web request otherwise exposes mutation tools while withholding their standing policy, producing false capability claims before the first operation. The earlier live measurement remains a required counter-test: five of twelve turns ended without a tool call under `Bash commands run under the "read-only" file sandbox.` The committed tool-owned attempt guidance postdates that measurement, so the replacement is selected through a new positive-control experiment under the current tool contract rather than assuming the old and current conditions match.
+
+**A separate model-context package.** Rejected because Cordis services can observe current runtime contributions directly, while approval and plan policy sections already live with their owners. A new package would add a shallow composition seam and documentation/gate surface for one internal adapter.
+
+**Enumerate writable temporary roots.** Rejected because the backend is selected later at `confine()`: bwrap, Landlock, Seatbelt, and the in-process filesystem fence do not grant one common temporary-path set. Host-specific paths in a standing request would be both unstable and overclaimed.
 
 ## Consequences
 
-A model can answer what file effects are currently possible before probing a tool, and the next request after `/permission` reflects the committed mode. This adds a small dynamic system section and intentionally invalidates the request prefix when policy changes; unchanged state remains cache-stable. The statement is guidance, not an enforcement guard: runtime safety still comes from `dsh-bash-sandbox` and `dsh-fs-sandbox` consuming the same resolved policy.

-Focused sandbox-policy tests pin all three texts, canonical roots, switch timing, byte stability, and replay. A keyless assembled ACP snapshot pins the request header through the real Loader composition, while the Web browser scenario drives `/permission` across all modes, inspects each exact `request/header`, and checks the model completes without a probing tool call; record mode exercises the real provider.
+Focused tests pin all modes, family combinations, contribution disposal, canonical roots, switch timing, and byte stability across different `TMPDIR` values. Keyless assembled snapshots pin the request header through real Loader compositions, including all three families. Real-provider selection uses pre-registered behavioral endpoints to choose wording, while keyless replay owns the selected denial-to-escalation trajectory.

 提供方在正常请求组装期间运行：此时 `/permission` 切换已经提交既有 `sandbox/mode` 事件，`request/header` 尚未记录。因此，渲染后的系统文本就是模型所见确切事实的持久化重建结果。会话状态不变时，重复组装会产生完全相同的字节；恢复与回放会折叠同一条持久模式事件和不可变的 `SessionHeader.cwd`，无需追赶状态。

 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

 - **Denials are result facts.** A failed run whose stderr carries the selected backend's own denial dialect — the signatures the provider stamps on every wrap (EROFS text under bwrap, EACCES under Landlock, EPERM under Seatbelt) — is reported as `BashRunResult.sandbox.denied: true` (conservative classification, read from the collected stderr tail); every CONFINED run also carries the mode it executed under (`result.sandbox.mode`) and the provider's enforcement completeness (`result.sandbox.enforcement`: `full`, or `partial` on an older Landlock ABI).
 - **Runner failures are sandbox failures, never command failures.** Foreground execution throws `SANDBOX_UNAVAILABLE`; a settled background process stamps `process.sandbox.runnerFailed`, which the bash producer renders through generic `task_output`. Spawn failures also pass through settlement, so confined background handles retain their mode/enforcement facts and release per-process accounting.

An approved escalation changes only that policy's mode; its session root stays attached. `resolve()` carries the policy onto the spec, so overlapping commands from different projects run, classify, and report under their own roots and modes. The capability fact `ctx.bash.sandboxMode` reports the configured default so the tool layer advertises escalation only when this executor is mounted.

 ## Why a shared home
 
-Two families enforce the same mode vocabulary: the sandboxed bash executor (`@deepseek-ai/dsh-bash-sandbox`) and the sandboxed filesystem provider (`@deepseek-ai/dsh-fs-sandbox`). If each resolved its own `mode` + `workspaceRoot`, the two could drift into a split world — bash confined to one root while fs fences another, exactly what [the sandbox RFC](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) warns against. Both tool layers resolve policy through `ctx.sandboxPolicy`, and both enforcing backends consume that complete per-call result. The [cross-family fs sandbox RFC](../../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.md) records the shared-policy decision.
+Filesystem tools, one-shot bash commands, and terminal sessions may enforce the same mode vocabulary in different combinations. If each resolved its own `mode` + `workspaceRoot`, they could drift into a split world, exactly what [the sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) warns against. Each enforcing backend consumes the complete owner-resolved policy and contributes its model-facing family; the current section therefore does not claim that an unfenced family shares another family's restrictions. The [cross-family fs sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.md) records the shared-policy decision.

Subject: [PATCH 063/278] test(snapshot): re-record cordis-inspect golden for
 the search card tag

The widened ToolResultView (adding SearchResultView and its member types) shows
in the tools API type surface that cordis_inspect reports, so the
cordis-inspect-jsdoc golden shifts. No other scenario renders a search result
body, so no other snapshot changes. Refreshed keyless.

 Ownership stays narrow. Approval policy remains the separate `approval:policy` section, plan mode remains `plan:policy`, and tool plugins continue to own schemas plus attempt, denial, and escalation guidance. The prompt states standing policy; filesystem, one-shot bash, and terminal backends remain the enforcement boundaries.
 
+## Wording evidence
+
+The wording experiment pre-registered preemptive refusal as its primary endpoint and required the old standing sentence to produce at least one refusal in twelve fresh sessions before any replacement could be judged. On 2026-07-30, commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` ran `deepseek-v4-flash` through the shipped Web composition with the exact positive-control sentence `Bash commands run under the "read-only" file sandbox.` and the current tool-owned attempt guidance. The control produced zero preemptive refusals and zero speculative escalations; all twelve sessions made an ordinary bash call, observed a denial, escalated in the same turn, received approval, and landed the requested file. No sample was excluded.
+
+The positive control therefore failed the pre-registered sensitivity gate. Candidate A and B were not run, and this experiment does not select or validate the current wording. It instead establishes that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
+
 ## Alternatives considered
 
 **Narrate only mode changes.** Rejected because it leaves a fresh session uninformed and makes the first denied operation the policy-discovery mechanism. It also requires a baseline definition that is unnecessary when current state can be rendered directly.

 A model can answer what registered file operations the standing mode governs before probing a tool, and the next request after `/permission` reflects the committed mode. This adds a small dynamic system section and intentionally invalidates the request prefix when policy or enforcing-family composition changes; unchanged state remains cache-stable. The statement is guidance, not an enforcement guard: runtime safety still comes from the registered filesystem, one-shot bash, and terminal backends consuming the same resolved policy.
 
-Focused tests pin all modes, family combinations, contribution disposal, canonical roots, switch timing, and byte stability across different `TMPDIR` values. Keyless assembled snapshots pin the request header through real Loader compositions, including all three families. Real-provider selection uses pre-registered behavioral endpoints to choose wording, while keyless replay owns the selected denial-to-escalation trajectory.

Keyless replay owns the neutral denial-to-escalation trajectory; it is a structural regression proof, not wording-selection evidence.

 归属范围保持收敛。批准策略仍由独立的 `approval:policy` 段落负责，计划模式仍由 `plan:policy` 负责，工具插件也继续负责各自的 schema，以及尝试、拒绝与升级引导。提示词负责说明常驻策略；文件系统、一次性 bash 与终端后端仍是强制执行边界。

+措辞实验预先登记「预防性拒绝」为主要终点，并要求旧常驻句子在十二个 fresh session 中至少产生一次拒绝，之后才能评判任何替代措辞。2026-07-30，commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` 通过已交付的 Web 组合运行 `deepseek-v4-flash`，使用精确的阳性对照句子 `Bash commands run under the "read-only" file sandbox.` 与当前工具归属方的尝试引导。对照组产生零次预防性拒绝和零次推测性升级；十二个会话全部先发起普通 bash 调用、观察到拒绝、在同一轮次升级、获得批准，并让所请求文件实际落盘。没有样本被排除。

+因此，阳性对照未通过预先登记的灵敏度门槛。Candidate A 与 B 均未运行，本实验不选择也不验证当前措辞。它只说明先前十二次中五次的结果无法在本任务与当前工具引导下复现；在声明模型行为率之前，需要更强的阳性对照或不同的任务分布。下述确定性测试只证明请求构造与回放真实一致。

 模型可以在试探工具前回答常驻模式管辖哪些已注册文件操作，且 `/permission` 后的下一个请求会反映已提交的模式。这会增加一个小型动态系统段落，并在策略或强制执行家族组合变化时有意使请求前缀缓存失效；状态不变时仍保持缓存稳定。该声明是引导，而不是强制执行护栏：运行时安全仍来自已注册的文件系统、一次性 bash 与终端后端消费同一项解析完成的策略。

The following skills are available in this session:\n\n\n- `15-05-premortem`: Use before starting risky work — rebases, large refactors, multi-file migrations, or deploys — to identify failure modes and mitigations in advance.\n- `acceptance-criteria`: 检查Acceptance Criteria格式和完整性，验证是否符合Given-When-Then结构、覆盖正常流程/边界条件/异常场景。适合在为User Story编写AC后、准备测试用例前使用，当需要验收AC质量时。帮助不熟悉BDD的PM/BA确保AC明确、可测试、覆盖完整，避免遗漏关键场景。\n- `agents-sdk`: Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `aico-pm-user-story-writing`: Transform requirements into well-structured User Stories using \"As a [user], I want [goal], So that [benefit]\" format with Given/When/Then acceptance criteria. Use this skill when: - User asks to \"write user story\", \"create story\", \"add story\" - User mentions \"user story\", \"backlog item\", \"story\" - Running /pm.plan and need to break PRD into implementable stories - Creating backlog items for development team - Need to formalize a requirement into standard story format - Converting feature req...\n- `algorithmic-art`: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.\n- `animation-vocabulary`: Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term (\"the bouncy thing when a popover opens\" → Pop in; \"the iOS rubber-band scroll\" → Rubber-banding). Use when the user asks \"what's it called when…\", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.\n- `app-comprehensive-test-generator`: Generate exhaustive user-flow and edge-case test scenarios from an app's codebase, produce scenario .md files, execute tests using connected or newly created MCPs, and produce an app.qa.report.md summarizing failures and suggested fixes.\n- `apple-design`: Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.\n- `brainstorming`: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- `brand-guidelines`: Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.\n- `canvas-design`: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.\n- `claude-api`: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answ...\n- `cloudflare`: Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), feature flags (Flagship), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `cloudflare-email-service`: Send and receive transactional emails with Cloudflare Email Service (Email Sending + Email Routing). Use when building email sending (Workers binding or REST API), email routing, Agents SDK email handling, or integrating email into any app — Workers, Node.js, Python, Go, etc. Also use for email deliverability, SPF/DKIM/DMARC, wrangler email setup, MCP email tools, or when a coding agent needs to send emails. Even for simple requests like \"add email to my Worker\" — this skill has critical conf...\n- `cloudflare-one`: Guides Cloudflare One Zero Trust and SASE work across Access, Gateway, WARP, Tunnel, Cloudflare WAN, DLP, CASB, device posture, and identity. Use when designing, configuring, troubleshooting, or reviewing Cloudflare One deployments. Retrieval-first: use current Cloudflare docs/API schemas instead of embedded product docs.\n- `cloudflare-one-migrations`: Plans migrations from Zscaler ZIA/ZPA, Palo Alto, legacy VPN, SWG, or SASE stacks to Cloudflare One. Use for migration assessments, policy mapping, rollout plans, and parity/gap analysis.\n- `code-review`: Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- `codebase-design`: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.\n- `content-refiner`: Refine verbose educational content by eliminating redundancy, tightening prose, and strengthening lesson connections. Use when content is wordy, repetitive, or lacks narrative flow between sections.\n- `context-compression`: This skill should be used when long-running agent sessions need context compression, structured summarization, compaction, token-per-task optimization, or durable handoff summaries that preserve decisions, files, risks, and next actions.\n- `create-feishu-doc`: Create a Feishu document and grant edit permissions to the user. Use when asked to write content to Feishu or create a document in a wiki space.\n- `design-compass`: Use when doing any product or UI design work — brainstorming a feature, starting a visual/interaction direction, reviewing half-built UI, or final-checking before ship; also when unsure which design skill applies. 产品设计 / 界面设计 / 交互设计 / UI review / 脑暴 / 视觉方向 / 设计验收时使用。\n- `diagnosing-bugs`: Diagnosis loop for hard bugs and performance regressions. Use when the user says \"diagnose\"/\"debug this\", or reports something broken/throwing/failing/slow.\n- `doc-coauthoring`: Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.\n- `docx`: Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. When Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks\n- `domain-modeling`: Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.\n- `durable-objects`: Create and review Cloudflare Durable Objects. Use when building stateful coordination (chat rooms, multiplayer games, booking systems), implementing RPC methods, SQLite storage, alarms, WebSockets, or reviewing DO code for best practices. Covers Workers integration, wrangler config, and testing with Vitest. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `ego-browser`: ego-browser (ego-lite) is a Chromium-based browser designed from the ground up to be friendly to both human users and AI Agents. AI Agents work in their own isolated space, reusing the user's login state without competing for the browser. Use this skill whenever the user needs to interact with a website opening pages, filling forms, clicking buttons, taking screenshots, extracting page data, testing web apps, logging into sites, automating browser operations, or any other browser automation t...\n- `emil-design-eng`: This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great.\n- `feishu-workflow`: 飞书文档全流程管理 — 搜索、创建、编辑 wiki 文档，支持内容排版、表格、代码块、白板\n- `find-animation-opportunities`: Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; it proposes motion with exact values, it does not implement it. Use when the user asks \"what could be animated here?\" or wants to \"make this feel more alive\". For fixing existing animations, use improve-animations or review-animations instead.\n- `frontend-design`: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- `gap-to-topic`: Turn a research area into a go/no-go decision dossier for ONE candidate thesis/proposal topic — a 3-gate verdict (is the gap open? is it a contribution? is it feasible?) with the evidence laid out so the researcher can verify it. Use when the user asks \"is this gap worth pursuing\", \"help me pick a thesis topic\", \"is this idea already taken\", \"find me a defensible research gap\", \"vet this research idea before I commit\", or \"should I do this\". NOT a literature review (use `literature-triage-mat...\n- `gc-minimal-zine-poster-v0-1`: Generate Minimal Zine Poster v0.1 poetic paper-poster prompts and the matching generated image. Use when the user gives a theme, sentence, object, mood, article idea, photo, or content brief and wants a quiet Japanese/Korean zine-like editorial poster with large negative space, aged paper texture, experimental typography, restrained color accents, and a generated bitmap image.\n- `grilling`: Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.\n- `grillme-workflow`: Use when implementing complex multi-step tasks that benefit from structured plan review, multi-model validation, and post-execution verification\n- `humanizer`: Remove signs of AI-generated writing from text. Use when editing or reviewing text to make it sound more natural and human-written. Based on Wikipedia's comprehensive \"Signs of AI writing\" guide. Detects and fixes patterns including: inflated symbolism, promotional language, superficial -ing analyses, vague attributions, em dash overuse, rule of three, AI vocabulary words, passive voice, negative parallelisms, and filler phrases.\n- `improve-animations`: Survey a codebase's animation and motion code as a senior motion advisor, then produce a prioritized audit and self-contained implementation plans for other agents (or cheaper models) to execute. Read-only on source code — it plans improvements, it does not apply them. Use when the user asks to \"improve the animations\", \"audit the motion\", \"make this app feel better\", or wants a roadmap of animation fixes rather than a review of a single diff.\n- `internal-comms`: A set of resources to help me write all kinds of internal communications, using the formats that my company likes to use. Claude should use this skill whenever asked to write some sort of internal communications (status reports, leadership updates, 3P updates, company newsletters, FAQs, incident reports, project updates, etc.).\n- `lark-approval`: 飞书审批：查询和处理审批待办/已办/实例，搜索可发起审批定义、查看定义详情并发起原生审批实例。当用户要处理审批任务、查看审批实例、搜索或发起审批时使用。审批待办不是飞书任务；非审批类待办走 lark-task。不负责创建审批定义；三方审批定义不走原生提单。\n- `lark-apps`: 妙搭（Spark/Miaoda）应用开发与托管：应用创建、本地全栈开发、云端生成迭代、创意设计（UI mockup / 可交互原型 / 线框图 / 落地页 / 仪表盘 / 幻灯片 deck / 视觉探索）、AI相关能力和飞书平台能力或者其他外部能力集成、日志/Trace/监控指标/PV/UV 查询、环境变量管理、应用角色与成员管理、自动化触发器（定时/记录变更/Webhook/飞书审批）。当用户要开发/新建一个系统·工具·平台·应用，或要本地开发 / 云端开发 / 修改 / 部署 / 发布 / 上线 / 拿可分享链接，或用 HTML 做页面·网站·部署到妙搭，或要设计 / design / mockup / prototype / wireframe / 做 PPT / deck / 视觉探索，或提到妙搭/Spark/Miaoda（应用运行时域名形如 *.aiforce.cloud）、应用数据库、应用文件存储、开放 API Key、可见范围、应用角色/角色成员、线上日志、接口请求量、错误量、延迟、访问量、环境变量、给妙搭应用配自动化任务/定时触发/审批通过后自动触发时使用。不负责...\n- `lark-attendance`: 飞书考勤打卡：查询自己的考勤打卡记录\n- `lark-base`: 飞书多维表格（Base）操作：建表、字段、记录、视图、统计、公式/lookup、表单、仪表盘、workflow、角色权限；遇到 Base/多维表格/bitable 或 /base/ 链接时使用。文件导入转 lark-drive，认证/授权转 lark-shared。\n- `lark-calendar`: 飞书日历：管理日历日程和会议室。查看/搜索日程、创建/更新日程、管理参会人、查询忙闲和推荐时段、预定会议室。当用户需要查看日程安排、创建/修改会议、查询/预定会议室时使用。不负责：查询过去的视频会议记录（走 lark-vc）、待办任务（走 lark-task）。\n- `lark-contact`: 飞书 / Lark 通讯录:按姓名 / 邮箱解析成 open_id,或按 open_id 反查姓名 / 部门 / 邮箱 / 联系方式 / 个人状态 / 签名。当用户提到某人姓名要下一步发消息 / 排日程,或拿到 open_id 想查具体信息时使用。不负责部门树遍历、按部门列员工、组织架构图,这类需求走原生 OpenAPI。\n- `lark-doc`: 飞书云文档（Docx / Wiki 文档）：读取和编辑飞书文档内容。当用户给出文档 URL 或 token，或需要查看、创建、编辑文档、插入或下载文档图片附件时使用。文档中嵌入的电子表格、多维表格、画板，先用本 skill 提取 token 再切到对应 skill。当用户给出 doubao.com 的 /docx/ 或 /wiki/ URL/token 时，也应直接使用本 skill；路由依据是 URL 路径模式和 token，而不是域名。不负责文档评论管理，也不负责表格或 Base 的数据操作。当用户明确要操作飞书思维笔记时，也使用本 skill。\n- `lark-drive`: 飞书云空间（云盘/云存储）：管理 Drive 文件和文件夹，包含上传/下载、创建文件夹、复制/移动/删除、查看元数据、评论/权限/订阅、标题、版本、飞书文档密级标签（secure labels）和本地文件导入。用户需要整理云盘目录、处理云空间资源 URL/token、判断链接类型/真实 token/标题，或导入 Word/Markdown/Excel/CSV/PPTX/.base 为 docx/sheet/bitable/slides 时使用；doubao.com 云空间 URL/token 也按资源路径和 token 路由，不回退 WebFetch。不负责：文档内容编辑（走 lark-doc）、表格/Base 表内数据操作（走 lark-sheets/lark-base）、知识空间节点/成员管理（走 lark-wiki）、原生 Markdown 文件读写/patch/diff（走 lark-markdown）。\n- `lark-event`: Lark/Feishu real-time event listening / subscribing / consuming: stream events as NDJSON via `lark-cli event consume <EventKey>` (covers IM messages/reactions/chat changes, Approval status changes, Task updates, VC meeting started/joined/ended, Minutes generated, Whiteboard updated, etc.).

The following skills are available in this session:\n\n\n- `15-05-premortem`: Use before starting risky work — rebases, large refactors, multi-file migrations, or deploys — to identify failure modes and mitigations in advance.\n- `acceptance-criteria`: 检查Acceptance Criteria格式和完整性，验证是否符合Given-When-Then结构、覆盖正常流程/边界条件/异常场景。适合在为User Story编写AC后、准备测试用例前使用，当需要验收AC质量时。帮助不熟悉BDD的PM/BA确保AC明确、可测试、覆盖完整，避免遗漏关键场景。\n- `agents-sdk`: Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `aico-pm-user-story-writing`: Transform requirements into well-structured User Stories using \"As a [user], I want [goal], So that [benefit]\" format with Given/When/Then acceptance criteria. Use this skill when: - User asks to \"write user story\", \"create story\", \"add story\" - User mentions \"user story\", \"backlog item\", \"story\" - Running /pm.plan and need to break PRD into implementable stories - Creating backlog items for development team - Need to formalize a requirement into standard story format - Converting feature req...\n- `algorithmic-art`: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.\n- `animation-vocabulary`: Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term (\"the bouncy thing when a popover opens\" → Pop in; \"the iOS rubber-band scroll\" → Rubber-banding). Use when the user asks \"what's it called when…\", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.\n- `app-comprehensive-test-generator`: Generate exhaustive user-flow and edge-case test scenarios from an app's codebase, produce scenario .md files, execute tests using connected or newly created MCPs, and produce an app.qa.report.md summarizing failures and suggested fixes.\n- `apple-design`: Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.\n- `brainstorming`: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- `brand-guidelines`: Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.\n- `canvas-design`: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.\n- `claude-api`: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answ...\n- `cloudflare`: Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), feature flags (Flagship), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `cloudflare-email-service`: Send and receive transactional emails with Cloudflare Email Service (Email Sending + Email Routing). Use when building email sending (Workers binding or REST API), email routing, Agents SDK email handling, or integrating email into any app — Workers, Node.js, Python, Go, etc. Also use for email deliverability, SPF/DKIM/DMARC, wrangler email setup, MCP email tools, or when a coding agent needs to send emails. Even for simple requests like \"add email to my Worker\" — this skill has critical conf...\n- `cloudflare-one`: Guides Cloudflare One Zero Trust and SASE work across Access, Gateway, WARP, Tunnel, Cloudflare WAN, DLP, CASB, device posture, and identity. Use when designing, configuring, troubleshooting, or reviewing Cloudflare One deployments. Retrieval-first: use current Cloudflare docs/API schemas instead of embedded product docs.\n- `cloudflare-one-migrations`: Plans migrations from Zscaler ZIA/ZPA, Palo Alto, legacy VPN, SWG, or SASE stacks to Cloudflare One. Use for migration assessments, policy mapping, rollout plans, and parity/gap analysis.\n- `code-review`: Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- `codebase-design`: Shared vocabulary for designing deep modules.

+Conversation domain: skeleton (header/tabs/composer/empty state), chat view (grouped step-summary flow, streaming tail isolation, text-icon context disclosures, an animated left-to-right gradient `Deep diving...` turn status, per-tool row slot with a bash sample registrant and the todo row), composer dock (session stats sticky with the input), input dock (hairline-separated queue rows plus the todo plan strip), minimal details panel, scope-addressed ConversationService. Contract: api-contracts v3 §7 plus the slot terminal design (store seat / props shares).
 
 The resident conversation shell survives no-session and session transitions. Without a current session it renders a disabled input bar; its root-scoped `conversation.hero.workspace` slot hosts the Workspace picker. Selecting a Workspace connects or reuses its Host-owned blank session and opens that session without replacing the shell. Blank sessions render the same composer body as active sessions, while the InputHub carries drafts across Workspace switches and mirrors them into the session store. In the active phase the session header occupies the top as ordinary column chrome; beneath it a scrollport (`data-conversation-scroll`) holds the flowing views and the sticky composer stack (stats dock + input docks + bar). Wheel over the textarea chains: the capped draft scrolls locally until its edge, then forwards to that host.

 常驻会话壳会跨无会话与会话状态切换而保留。没有当前会话时，它会渲染禁用输入栏；其根作用域的 `conversation.hero.workspace` slot 承载 Workspace 选择器。选择 Workspace 会连接或复用由 Host 拥有的空白会话，并在不替换会话壳的情况下打开该会话。空白会话与活跃会话渲染相同的输入区主体；InputHub 则在 Workspace 切换间携带草稿，并将草稿镜像到会话 store。活跃阶段会话标题栏以普通列 chrome 占据顶部；其下滚动容器（`data-conversation-scroll`）承载流动排版的各视图与 sticky 编辑器栈（统计 dock＋输入区 dock＋输入栏）。textarea 上的滚轮会链式处理：限高草稿先在本地滚动，到达边缘后再转交给该宿主。

 ## Markdown rendering
 
-`MarkdownText` renders GFM from untrusted assistant output through React elements. It omits raw HTML, neutralizes relative and non-HTTP(S)/mailto links, opens HTTP(S) links with safe external-link attributes, and renders image alt text without loading remote resources; `MessageText` remains the literal-text primitive for user-authored content. `extractMarkdownPlainText` removes Markdown presentation markup for compact labels while preserving raw HTML as literal text. Element spacing, tables, links, and inline code use the same `--dsw-alias-markdown-*` / `--dsw-font-markdown-*` tokens as deepsuite `@deepseek/md`. Fenced blocks render through `CodeBlock` (language banner, copy control, shiki for the registered grammars).

 ## Markdown 渲染
 
-`MarkdownText` 通过 React 元素渲染来自不受信任 assistant 输出的 GFM。它会省略原始 HTML，使相对链接及非 HTTP(S)/mailto 链接失效，以安全的外部链接属性打开 HTTP(S) 链接，并只渲染图片 alt 文本而不加载远程资源；`MessageText` 仍是用户创作内容使用的字面文本原语。`extractMarkdownPlainText` 会移除 Markdown 呈现标记以用于紧凑标签，同时将原始 HTML 保留为字面文本。元素间距、表格、链接与行内代码使用与 deepsuite `@deepseek/md` 相同的 `--dsw-alias-markdown-*` / `--dsw-font-markdown-*` token。围栏代码块通过 `CodeBlock` 渲染（语言横幅、复制控件，以及对已注册语法使用 shiki）。

 ## 终端输出
 
 `TerminalBlock` 将一条 shell 命令渲染为终端表层：命令的每一行各占一个提示行（缩短后的 `cwd` 标签只出现在第一行，因为视图只知道一个工作目录，而一个 `cd` 就会让后面的行去到别处，标签之后是该行）、命令输出、非零退出码或终止信号对应的状态胶囊，以及写入原始 `output` prop 的复制控件。一枚运行状态 `StateDot` 为整次调用标记一次，位于第一行，以脱离文档流的方式落在卡片以自身左内边距预留的落区中，因此它位于卡片盒之内、提示文字之左。它用到 `StateDot` 的三种状态——`running` 期间为追逐动画，与渲染状态胶囊相同的退出状态为红色，其余为绿色——因此卡片直接陈述其命令是否仍在运行，而不是让人从有无输出中推断；由于 `StateDot` 是 `aria-hidden`，它携带一处视觉隐藏的文本标签。无论多少行都只有一枚状态点是有意为之：退出状态属于整次调用，因此每行一枚就会声称一个视图并不携带的逐行结果。命令文本使用 `white-space: pre`，因此重复空格、制表符与缩进续行都原样呈现，同时该行仍保持单行并以省略号截断。ANSI 转义序列通过运行时依赖 `anser` 解析为 React span；光标移动在剥除无显示意义控制符之前先重放进逐行的列缓冲，因为回车与退格**只移动**光标：单是 `100%` 加回车再加 `OK` 显示为 `OK0%`，而 spinner 随重绘写出的 `\x1b[K` 会擦掉尾巴，因此 `100%\r\x1b[KOK` 显示为 `OK`。行内擦除的三种参数形式都被遵循，光标按终端列推进（8 列制表位；emoji 与 CJK 占两列；组合标记不占列），SGR 状态按单元格归一化存储，与终端一致，并跨行延续、在行结束时的状态处收束；基础 16 色前景色映射到 `--dsw-*` token，而 256 色板与真彩色值按字面 rgb 透传。输出保持 `white-space: pre` 并支持横向滚动，因此按列对齐的输出保留其对齐而不会软换行；超过 `maxLines`（默认 16，与 TUI 转录相同的切分算法）时折叠为头部切片加尾部切片，由展开按钮控制。原理：[Web 终端卡片笔记](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md)。

- DetailsPanel: render the flattened result content below the web card, so a
  web_fetch's fetched body (and a search's answer/source markdown) stays
  visible on the panel's single-call reading surface — the card is a summary.
- WebBlock: the collapsed source tail keeps each source's original citation
  number via 
  • , and the expand control is a marker-less 
  •  so the
  
       is valid HTML; an empty-hostname URL (file:/data:) falls back to the raw
  URL so a label is never blank.
- web-row / GenericToolCard: both spread WebBlock uniformly with maxSources
  (fetch ignores it, like TerminalBlock's maxLines), dropping the duplicated
  per-kind conditional.
- Docs: WebBlock added to the ui-primitives README (both languages) with a Web
  retrieval section; the ui-conversation README's "inline licensed for this
  intent alone" claim de-absolutized and a web-card paragraph added; the Agent
  Note's safe-link description corrected to the http(s) subset of MarkdownText's
  allowlist (mailto excluded). Fixture source comment aligned with its data.
- Tests: ol numbering + marker-less expander, empty-hostname label fallback,
  the fetched body visible in the panel.

 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 same allowlist MarkdownText applies to untrusted assistant-authored links.** 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:` 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.

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.

 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.

+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, or a `card` tag this client version does not know. 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. 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)).
 
 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: '', 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).

 `TerminalBlock` renders a shell command as a terminal surface: one prompt row per line of the command (the shortened `cwd` label on the first row only, since the view knows one working directory and a `cd` moves later lines elsewhere, then that line), the command's output, a status pill for a non-zero exit code or a terminating signal, and a copy control that writes the raw `output` prop. A run-state `StateDot` marks the call once, on the first row, out of flow in a gutter the card reserves as its own left padding, so the dot sits inside the card box yet left of the prompt text. It reaches three of `StateDot`'s states — the chase while `running`, red for the same exit status that renders the pill, green otherwise — so a card states whether its command is still running rather than leaving that to be inferred from the presence of output; it carries one visually hidden text label because `StateDot` is `aria-hidden`. One dot regardless of line count is deliberate: the exit status is the whole call's, so a dot per line would claim a per-line outcome the view does not carry. Command text is `white-space: pre`, so repeated spaces, tabs, and an indented continuation render verbatim while the row stays single-line and ellipsizes. ANSI escape sequences are parsed with the `anser` runtime dependency into React spans; cursor movements replay into a per-line column buffer before inert controls are stripped, since carriage return and backspace only MOVE the cursor: `100%` + CR + `OK` alone shows `OK0%`, while the `\x1b[K` a spinner writes with its redraw erases the tail so `100%\r\x1b[KOK` shows `OK`. Erase-in-line is honored in all three parameter forms, the cursor advances by terminal columns (8-column tab stops, two for emoji and CJK, none for a combining mark), and SGR state is normalized per cell as a terminal stores it, threading across lines and closing at the state the line ended in; basic-16 foreground colors map onto `--dsw-*` tokens, while 256-palette and truecolor values pass through as literal rgb. Output keeps `white-space: pre` with horizontal scrolling, so column-aligned output holds its alignment instead of soft-wrapping, and collapses to a head slice plus a tail slice past `maxLines` (default 16, the TUI transcript's split arithmetic) behind an expand button. Rationale: [the web terminal card note](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md).
 
+## Web retrieval
+
+`WebBlock` renders a completed web retrieval, one component for both kinds of the `web` render intent (discriminated by `kind`). A `search` shows an optional provider answer (through `MarkdownText`) above an ordered citation list: each source is a safe external link labelled by its title, or its hostname, falling back to the raw URL when the URL does not parse or has no hostname (a `file:`/`data:` URL) so a label is never blank; its snippet and publication date render below it. Only http(s) URLs become anchors (`target`/`rel` set) — the http(s) subset of the allowlist `MarkdownText` applies to untrusted links (it also permits `mailto:`, excluded here); any other URL renders as plain text. A long list caps at `maxSources` (default 16, the TerminalBlock split arithmetic) with a head/tail collapse; the collapsed tail keeps each source's original citation number via `
  • `, and the expand control is a marker-less `
  • ` so the `
      ` stays valid HTML. A `fetch` shows a compact summary: the linked final URL and its HTTP status. Both mark a capped retrieval. Rationale: [the web result card note](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card-frontend.md).

HoverCard closed on the first pointerleave and rendered its card pointer-events:none, but the card sits 8px off the anchor, so every path to it crossed ground belonging to neither. The row action menus put closeOnPointerLeave's handler on the portaled list, so aiming back at the ... trigger that opened it, or overshooting a list edge, closed it with no window to come back. usePointerGrace owns one cancelable delayed close (200ms) shared by both atoms: leaving arms it, returning cancels it. The hover card becomes hit-testable so resting on it holds it open, and Menu moves pointer-leave dismissal to the wrapper span, where React's enter/leave traversal makes trigger and portaled list one region.

The `apps/cli` `parallel-file-reads` terminal golden (`examples/tui-agent/tests/snapshots/parallel-file-reads/terminal.expected.txt`) pins exactly that: a real replay executes the read tool, renders it through the new `card: 'read'` gate, and the golden's dim-Markdown rows are byte-for-byte what a generic read produced before this card existed. ## Related diff --git a/.agents/notes/implemented/feature/2026-07-30-web-read-card.zh.md b/.agents/notes/implemented/feature/2026-07-30-web-read-card.zh.md index c3e3ec1c3c..bfcc17e782 100644 --- a/.agents/notes/implemented/feature/2026-07-30-web-read-card.zh.md +++ b/.agents/notes/implemented/feature/2026-07-30-web-read-card.zh.md @@ -4,13 +4,13 @@ Status: implemented [English](2026-07-30-web-read-card.md) | 中文 -## 问题 +## Problem `read` 工具返回规范化输出对象 `{ path, offset, lines: [{ number, text }], totalLines }`，但它的展示层把这个结构压平了。`presentCall` 声明为 `GenericCallView`（`kind: 'read'`，一个跟随定位），`presentResult` 返回 `GenericResultView`，其唯一内容是剥掉 `…file…` 信封后的面向模型文本。收到该视图的 UI 只看到一个压平的文本块：行号以 `N: ` 前缀烘焙进文本、文件语言未知、`totalLines` 丢失。capable 客户端无法像渲染 diff 那样渲染一次 read——即带行号、语法高亮、行号槽与内容分离的代码视图。 结构化数据在下游无法恢复。线上（wire）的工具结果只携带面向模型的 `ContentBlock[]`（已渲染文本）加上一个不透明的 `meta`；规范化输出对象留在工具内，从不到达客户端或会话日志。因此想要行数组、总数和语言提示的客户端无法从 `N: text` 文本里解析回它们——工具必须把它们投影到一个会持久化的通道上。 -## 决策 +## Decision 给[渲染意图 union](../architecture/2026-07-02-tool-render-intent-union.md) 新增第四个 `card` 标签 `read`——仅在结果侧。`ToolResultView` 增加 `ReadResultView { card: 'read'; title?; path; lines: ReadFileLine[]; totalLines; lang?; content?

A run-state `StateDot` marks the call once, on the first row, out of flow in a gutter the card reserves as its own left padding, so the dot sits inside the card box yet left of the prompt text. It reaches three of `StateDot`'s states — the chase while `running`, red for the same exit status that renders the pill, green otherwise — so a card states whether its command is still running rather than leaving that to be inferred from the presence of output; it carries one visually hidden text label because `StateDot` is `aria-hidden`. One dot regardless of line count is deliberate: the exit status is the whole call's, so a dot per line would claim a per-line outcome the view does not carry. Command text is `white-space: pre`, so repeated spaces, tabs, and an indented continuation render verbatim while the row stays single-line and ellipsizes. ANSI escape sequences are parsed with the `anser` runtime dependency into React spans; cursor movements replay into a per-line column buffer before inert controls are stripped, since carriage return and backspace only MOVE the cursor: `100%` + CR + `OK` alone shows `OK0%`, while the `\x1b[K` a spinner writes with its redraw erases the tail so `100%\r\x1b[KOK` shows `OK`. Erase-in-line is honored in all three parameter forms, the cursor advances by terminal columns (8-column tab stops, two for emoji and CJK, none for a combining mark), and SGR state is normalized per cell as a terminal stores it, threading across lines and closing at the state the line ended in; basic-16 foreground colors map onto `--dsw-*` tokens, while 256-palette and truecolor values pass through as literal rgb. Output keeps `white-space: pre` with horizontal scrolling, so column-aligned output holds its alignment instead of soft-wrapping, and collapses to a head slice plus a tail slice past `maxLines` (default 16, the TUI transcript's split arithmetic) behind an expand button. Rationale: [the web terminal card note](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md). +## Search results + +`SearchBlock` renders a completed search, one component for both kinds (discriminated by `kind`). A `matches` (grep) shows each file as a bold path header with its `lineNumber: line` rows, the per-file group collapsible; a `paths` (glob) shows a flat path list. Both flatten to one row list the height cap slices head/tail over (default 16, the TerminalBlock split arithmetic), and neither soft-wraps — a long match line or path scrolls horizontally instead of folding. The banner summary folds the pre-cap total in when the tool capped the result (`显示 X / 共 N 处匹配 · K 个文件` for grep, `显示 X / 共 N 个路径` for glob), so the card never presents a capped result as complete; a copy control writes the whole structured result regardless of the cap or which groups are collapsed.

Bring the TUI diff footer onto the same terminator rule and distinct-path
count the Web DiffBlock uses (a trailing newline terminates its line; two
hunks in one file read as 1 file), so the two front ends' `+A -R · N file(s)`
footers agree. Reserve space in the diff path header for the floating copy
button so a long path no longer scrolls under it. Pass the tool's raw path to
the injected openFile (which already resolves against cwd) instead of resolving
twice. Rename the shared block-body CSS class to a card-neutral cardBody so a
terminal-spacing tweak cannot silently move the diff card. Add a same-file
two-hunk TUI unit test and an assembled built-boot assertion that the write
turn renders +1 -0 · 1 file end to end.

 `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, with one deliberate divergence noted below (the file count):
+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 — the divergence from the TUI, whose footer uses `diffs.length` and so reads two hunks in one file as `2 files` where this reads `1 file`.
+- **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.

 `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，仅文件计数一处刻意分歧（见下）：
+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)` 页脚统计**去重后的路径数** —— 这是与 TUI 的分歧:TUI 页脚用 `diffs.length`，同文件两个 hunk 在那里读作 `2 files`，此处读作 `1 file`。
+- **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。

 and correct grammar docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Top-level read samples in read-card.spec use the read tool's real file_path
schema key (web_fetch keeps its own path key); the Input-JSON assertion follows.
The LANGS/LANG_ALIASES JSDoc no longer claims the TypeScript grammar embeds
JSX/TSX — shiki's TS grammar tokenizes JSX approximately, an accepted trade to
keep one JS-family boot grammar.

Subject: [PATCH 091/278] fix(web): update diff-card tests for the openFile
 no-double-resolve contract
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The coverage lane caught a regression in the prior commit: FileMutationRow now
passes the tool's raw path to the injected openFile (which resolves against cwd
in apply.ts), but diff-card.spec still asserted the row pre-resolved. Assert on
the raw path instead. Also fix the built-boot diff assertion to match on the
line body and footer text — the `+ ` prefix is a CSS ::before, absent from
textContent.

Subject: [PATCH 092/278] refactor(fs): minimize and cap search card meta; keep
 TUI byte-identical

Address the review of the search render card:

- The search result view carries no `content`: it was a no-op for every
  consumer and serialized the whole search text twice. A UI without a search
  card falls back to the raw tool/result content; the TUI stays byte-identical
  to the pre-search-card generic fallback.
- Bound the serialized presentationMeta with a configurable searchMetaMaxBytes
  (default 64 KiB): the inline item cap does not bound bytes, and spill-policy
  only shrinks content, never meta. capMetaBytes drops trailing groups/paths.
- Share one retention pass (retainGrepMatches/retainGlobPaths in search-core)
  between the model-facing render and the meta projection; remove the second
  cap/preview implementation and the presentation<->grep module cycle by
  moving GrepMatch/previewLine to search-core.
- Rename the result-view discriminant kind -> shape so it no longer collides
  with GenericCallView.kind (ToolCallKind, whose values include 'search').
- Narrow the entry export surface to consumed symbols.
- Sync the three bilingual ToolResultView doc pairs and the Agent Note pair;
  document the deliberate empty-card acceptance vs diffsFromMeta.
- Regenerate config/tool/cordis catalogs for the new config field.

 ## Problem
 
-`grep` and `glob` return structured canonical values — `grep` a flat `{ matches: [{ path, lineNumber, line }] }`, `glob` a `{ paths: string[] }` — but every UI only ever saw their model-facing render text: `grep` groups its matches under file headers with `Line N:` rows, `glob` prints a newline-joined path list, and both append a spill footer when the inline cap ({@link module:@deepseek-ai/dsh-tool-fs-search/grep} `grepMaxMatches`, default 250; {@link module:@deepseek-ai/dsh-tool-fs-search/glob} `globMaxResults`, default 100) drops later results to a spill file. A web frontend that wants to render a search result as an expandable per-file group of matches, or as a selectable path list, had to re-parse that text. Both tools already declared a call-time [render intent](../architecture/2026-07-02-tool-render-intent-union.md) (`GenericCallView`, `kind: 'search'`) but no result-time view, so the completed call fell back to the generic card that renders the raw text.

 The structured canonical value does not cross the wire: only the model-facing render text and, when a tool declares `output.presentationMeta`, a JSON metadata payload reach the client, threaded through the `tool/result` event ([canonical-output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). A result-time view carrying structured data therefore has to project that data into `presentationMeta` and read it back in `presentResult` — the same path `write`/`edit` use for their diff cards.
 
 ## Decision
 
-`packages/core/tools/src/presentation.ts` adds `card: 'search'` to the `ToolResultView` union as `SearchResultView`, a `kind`-discriminated view that expresses both tools' shapes: `SearchMatchesResultView` (`kind: 'matches'`) carries `grep`'s matches grouped by file as `files: { path, matches: { lineNumber, line }[] }[]`, and `SearchPathsResultView` (`kind: 'paths'`) carries `glob`'s flat `paths: string[]`. Both carry `truncated: boolean` and `total: number`, and an optional `content?: ContentBlock[]`.

Both carry `truncated: boolean` and `total: number`.
 
-One view with two shapes rather than two cards, because both tools are the same visual object — a search result — and a web consumer switches on one `card` value, then on `kind` for the row shape. The discriminated `kind` keeps each shape's fields non-optional (a matches view always has `files`, a paths view always has `paths`) instead of a single interface where every shape-specific field is optional.
+The discriminant is `shape`, not `kind`, deliberately: the same presentation module already gives `GenericCallView` a `kind: ToolCallKind` field whose values include `'search'` (the icon category). A bridge holding a `ToolCallView | ToolResultView` would see two `kind` fields with two meanings; `shape` for the result variant keeps the two apart.

+One view with two shapes rather than two cards, because both tools are the same visual object — a search result — and a web consumer switches on one `card` value, then on `shape` for the row layout. The discriminated `shape` keeps each variant's fields non-optional (a matches view always has `files`, a paths view always has `paths`) instead of a single interface where every shape-specific field is optional.
+
+The view carries **no** result text. An earlier revision attached the model-facing `result.content` to the view; that was a no-op for every consumer (the TUI already falls back to `result.content`, and web fallbacks read the raw `tool/result` content), and it serialized the whole search text a second time into the persisted view. The view is the structured shape only; a UI without a search card falls back to the raw `tool/result` content.
 
 The card tag is result-time only. A search call stays a `GenericCallView` (`kind: 'search'`): the pending state has no matches or paths to show, so there is nothing a `SearchCallView` would carry that the generic title does not. This is the asymmetry with the terminal card, whose call view carries the command, cwd, and description that exist before execution; a search's structured content exists only after `execute`.
 
-`packages/fs/tool-fs-search/src/presentation.ts` owns the projection and the narrowing. `grepSearchMeta`/`globSearchMeta` project the canonical value into a `SearchMeta` payload each tool declares as `output.presentationMeta`; `presentGrepResult`/`presentGlobResult` read `result.meta` back through `searchViewFromMeta` and attach the model-facing `result.content` as the view's `content`. The projections apply the SAME inline cap and per-line preview budget the model-facing render applies, and report `total` as every result the search found (before capping) with `truncated` set when the cap dropped results. This is the truncation-honesty point: the model saw a capped inline result plus a spill footer, so the card must not present the retained page as the complete result — a UI reads `truncated`/`total` to show a capped indicator rather than claiming completeness the model never had.

They consume the SAME retained result the model-facing render consumes — `retainGrepMatches`/`retainGlobPaths` in `search-core.ts` run the inline cap and per-line preview budget ONCE, and both the render and the projection take that outcome — so text and card never disagree about which results survived, and there is no second retention pass. `total` is every result the search found (before capping); `truncated` is set when the cap dropped results. This is the truncation-honesty point: the model saw a capped inline result plus a spill footer, so the card must not present the retained page as the complete result — a UI reads `truncated`/`total` to show a capped indicator rather than claiming completeness the model never had.
 
-`searchViewFromMeta` narrows the opaque `meta` defensively and returns `undefined` on any malformed or absent payload, exactly as `diffsFromMeta` does, so a presenter run on an older or hand-edited replayed log falls back to the generic card instead of throwing. `presentResult` returns `undefined` for a failed result, for absent meta (a nested `run_code` dispatch computes no `presentationMeta`), and for the other tool's meta shape (each presenter narrows to its own `kind`).
+**The meta has its own byte budget.** The inline cap bounds the item COUNT, but the retained matches of a broad search (hundreds of long lines) can still serialize to hundreds of kilobytes, and `meta` is persisted with the session log and re-sent on every request. A deployment's final output budget (`dsh-spill-policy`, `maxInlineBytes`) only shrinks a result's `content` — `PostToolDecision` has no `meta` channel — so the projection owns keeping `meta` bounded. `capMetaBytes` drops trailing file groups / paths until the serialized meta fits `searchMetaMaxBytes` (config, default 64 KiB) and marks the result `truncated`. A single item too large to fit on its own is kept: the invariant is a bounded payload wherever droppable, never an empty card that hides a real result.
 
-The `SearchMeta` member shapes are object-literal `type` aliases, not the `SearchFileMatches`/`SearchLineMatch` interfaces the view exposes. Only a type alias is assignable to the `JsonValue` index signature `presentationMeta` returns; the two are structurally identical, so the projected value still reads back as a `SearchResultView`.
+`searchViewFromMeta` narrows the opaque `meta` defensively and returns `undefined` on any malformed or absent payload, so a presenter run on an older or hand-edited replayed log falls back to the generic card instead of throwing. It DOES accept a zero-result payload (`files: []` / `paths: []`) as a valid empty card — this is a deliberate departure from the mirrored `diffsFromMeta`, which rejects empty `diffs`, because a zero-match grep is a legitimate result a UI shows as "no matches", not an absent projection. `presentResult` returns `undefined` for a failed result, for absent meta (a nested `run_code` dispatch computes no `presentationMeta`), and for the other tool's meta shape (each presenter narrows to its own `shape`).
 
-The TUI (`packages/ui/tui/src/components/transcript.ts`) needs no dedicated arm: its result-view switch handles `terminal` and `diff` explicitly and falls through to a generic arm that renders `view.content ?? this.result?.content`. Because `SearchResultView` carries the model-facing text as `content`, the TUI renders it as the same text it already showed. The web frontend that renders the structured `files`/`paths` shape is a separate later PR; this PR is the backend contract and its two producers.

 ## Alternatives considered
 
-**A single flat `SearchResultView` interface with optional `files?` and `paths?`.** Rejected: it makes both shape-specific fields optional on every value and lets a malformed view carry both or neither. The `kind` discriminant keeps each shape's fields required and lets a consumer switch exhaustively.

-**A call-time `SearchCallView` mirroring the terminal card's both-sides symmetry.** Rejected: a search call has no matches or paths before `execute`, so the view would carry only the title the `GenericCallView` already carries. The terminal card's call view earns its tag because a command, cwd, and description exist at call time; a search's structured content does not.
+**Reuse `kind` as the shape discriminant.** Rejected: `kind` already means `ToolCallKind` (the icon category, whose values include `'search'`) on the call view in the same module. A second `kind` with a different meaning on the result view collides for any bridge holding both.
 
-**Carry the structured result in a bespoke channel instead of `presentationMeta`.** Rejected: the canonical value is execution-local and never reaches the client, and `presentationMeta` is the established seam that persists a tool's JSON presentation payload with `tool/result` and threads it back to `presentResult`. Adding a second channel would duplicate that path.
+**Attach the model-facing text as the view's `content`.** Rejected: a no-op for every current consumer and a second serialization of the whole search text into the persisted view. The view is the structured shape; text fallback reads the raw result content.
+
+**A meta channel on `PostToolDecision` so `dsh-spill-policy` bounds `meta` like it bounds `content`.** Rejected for this PR: it changes the core tool decision contract and the spill-policy plugin for one tool's payload. The projection bounding its own `meta` at a config byte cap is self-contained and keeps the seam unchanged.
+
+**A call-time `SearchCallView` mirroring the terminal card's both-sides symmetry.** Rejected: a search call has no matches or paths before `execute`, so the view would carry only the title the `GenericCallView` already carries.
 
 ## Consequences
 
-`grep` and `glob` now compute `presentationMeta` on every non-nested successful call, a bounded projection over the already-parsed matches or paths. The projection re-applies the retention cap the render already applied, so the retained set is computed twice per call; the input is bounded by the raw-output cap, so this is not a new scaling concern.
+`grep` and `glob` now compute `presentationMeta` on every non-nested successful call, a bounded projection over the already-retained matches or paths — the same retention outcome the render consumes, so there is no second retention pass and no doubled search text on the wire. The serialized meta is bounded by `searchMetaMaxBytes`, so a broad search no longer persists an unbounded structured copy into the session log.
 
-A UI without a search card renders the attached `content` text, so no consumer regresses. The web consumer that renders the structured shape reads `truncated`/`total` and the per-file groups; because the view carries only the retained page, a UI wanting the complete result follows the spill locator in the model-facing text, exactly as the model does.

-`packages/fs/tool-fs-search/tests/presentation.spec.ts` pins the pure layer: `groupMatchesByFile`'s first-seen file order, `grepSearchMeta`/`globSearchMeta` projection with the cap applied and `total` reporting the pre-cap count, the per-line preview budget on a projected match line, and `searchViewFromMeta`'s narrowing of both good shapes plus every malformed case (non-object/array meta, missing or mistyped `truncated`/`total`, unknown `kind`, malformed `files` entries, non-string `paths`). `packages/fs/tool-fs-search/tests/tools.spec.ts` pins the wiring through the real tool registry: a capped `grep`/`glob` execute produces the `SearchMeta` on `result.meta` and `presentResult` builds the search view with `content` attached, a nested `run_code` dispatch computes no meta so `presentResult` falls back, and a failed or cross-shape or malformed result falls back to the generic card.

+## 问题
 
-`grep` 与 `glob` 返回结构化的规范值——`grep` 是扁平的 `{ matches: [{ path, lineNumber, line }] }`，`glob` 是 `{ paths: string[] }`——但每一个 UI 见到的只有它们面向模型的渲染文本：`grep` 把匹配按文件分组，文件头下是 `Line N:` 行；`glob` 打印换行连接的路径列表；当内联上限（{@link module:@deepseek-ai/dsh-tool-fs-search/grep} `grepMaxMatches`，默认 250；{@link module:@deepseek-ai/dsh-tool-fs-search/glob} `globMaxResults`，默认 100）把后续结果溢出到 spill 文件时，两者都追加一段溢出脚注。想把搜索结果渲染成可展开的按文件分组匹配、或渲染成可选择的路径列表的 web 前端，只能去重新解析这段文本。两个工具都已声明了调用期的[渲染意图](../architecture/2026-07-02-tool-render-intent-union.md)（`GenericCallView`，`kind: 'search'`），但没有结果期视图，于是已完成的调用回退到渲染原始文本的通用卡片。

-结构化的规范值不过线：只有面向模型的渲染文本、以及当工具声明 `output.presentationMeta` 时的一段 JSON 元数据抵达客户端，二者通过 `tool/result` 事件穿线（[规范输出契约](../architecture/2026-07-20-canonical-tool-output-contract.md)）。因此携带结构化数据的结果期视图必须把该数据投射进 `presentationMeta`，再在 `presentResult` 里读回——正是 `write`/`edit` 的 diff 卡片所走的路径。

-## Decision
+## 决定
 
-`packages/core/tools/src/presentation.ts` 向 `ToolResultView` 联合类型加入 `card: 'search'`，即 `SearchResultView`：一个以 `kind` 区分的视图，表达两个工具的形状。`SearchMatchesResultView`（`kind: 'matches'`）以 `files: { path, matches: { lineNumber, line }[] }[]` 携带 `grep` 按文件分组的匹配；`SearchPathsResultView`（`kind: 'paths'`）携带 `glob` 的扁平 `paths: string[]`。两者都携带 `truncated: boolean` 与 `total: number`，以及可选的 `content?: ContentBlock[]`。
+`packages/core/tools/src/presentation.ts` 把 `card: 'search'` 作为 `SearchResultView` 加入 `ToolResultView` 联合，这是一个以 `shape` 判别的视图，表达两个工具的形状：`SearchMatchesResultView`（`shape: 'matches'`）以 `files: { path, matches: { lineNumber, line }[] }[]` 承载 `grep` 按文件分组的匹配，`SearchPathsResultView`（`shape: 'paths'`）承载 `glob` 的扁平 `paths: string[]`。两者都带 `truncated: boolean` 与 `total: number`。
 
-一个视图两种形状，而非两张卡片，因为两个工具是同一个视觉对象——一个搜索结果——web 消费方先在一个 `card` 值上分派，再在 `kind` 上分派行的形状。区分性的 `kind` 让每种形状各自的字段保持非可选（matches 视图恒有 `files`，paths 视图恒有 `paths`），而不是让所有形状相关字段都变成可选的单一接口。
+判别子是 `shape` 而非 `kind`，是刻意为之：同一个 presentation 模块已经给 `GenericCallView` 一个 `kind: ToolCallKind` 字段，其取值恰好包含 `'search'`（图标类别）。持有 `ToolCallView | ToolResultView` 的桥接层会看到两个含义不同的 `kind` 字段；结果变体用 `shape` 把两者分开。
 
-卡片标签只在结果期。搜索调用仍是 `GenericCallView`（`kind: 'search'`）：pending 状态没有匹配或路径可展示，因此 `SearchCallView` 能携带的东西不会超出通用标题。这是与 terminal 卡片的不对称之处——terminal 的调用视图携带执行前就存在的命令、cwd 与描述；而搜索的结构化内容只在 `execute` 之后才存在。
+用一个带两种形状的视图而非两张卡片，因为两个工具是同一个视觉对象 —— 一个搜索结果 —— web 消费方先在一个 `card` 值上分支，再在 `shape` 上分支决定行布局。判别式 `shape` 让每个变体的字段保持非可选（matches 视图总有 `files`，paths 视图总有 `paths`），而不是一个所有形状相关字段都可选的单一接口。
 
-`packages/fs/tool-fs-search/src/presentation.ts` 拥有投射与收窄。`grepSearchMeta`/`globSearchMeta` 把规范值投射为一段 `SearchMeta`，各工具将其声明为 `output.presentationMeta`；`presentGrepResult`/`presentGlobResult` 通过 `searchViewFromMeta` 把 `result.meta` 读回，并把面向模型的 `result.content` 作为视图的 `content` 附上。投射施加与面向模型渲染相同的内联上限与每行预览预算，并把 `total` 报告为搜索找到的全部结果（截断之前），当上限丢弃了结果时把 `truncated` 置为真。这就是截断诚实性的要点：模型看到的是被截断的内联结果加一段溢出脚注，因此卡片不得把保留的那一页当作完整结果呈现——UI 读取 `truncated`/`total` 去展示截断指示，而非宣称模型从未拥有的完整性。
+该视图**不**携带结果文本。早期版本曾把面向模型的 `result.content` 附到视图上；那对每个消费方都是 no-op（TUI 本就回退到 `result.content`，web 回退读原始 `tool/result` 内容），却把整段搜索文本又序列化进持久化视图一遍。视图只承载结构化形状；无 search 卡片的 UI 回退到原始 `tool/result` 内容。
 
-`searchViewFromMeta` 防御性地收窄不透明的 `meta`，对任何畸形或缺失的 payload 返回 `undefined`，与 `diffsFromMeta` 完全一致，因此在较旧或手工编辑过的回放日志上运行的呈现器会回退到通用卡片而非抛错。`presentResult` 对失败结果、对缺失的 meta（嵌套 `run_code` 分发不计算 `presentationMeta`）、对另一个工具的 meta 形状（每个呈现器只收窄到自己的 `kind`）都返回 `undefined`。
+卡片标签只在结果时存在。搜索调用保持为 `GenericCallView`（`kind: 'search'`）：pending 状态没有匹配或路径可展示，所以 `SearchCallView` 能携带的东西不会比 generic 标题更多。这是与 terminal 卡片的不对称之处 —— terminal 的调用视图携带执行前就存在的命令、cwd、description；搜索的结构化内容只在 `execute` 之后才存在。
 
-`SearchMeta` 的成员形状是对象字面量 `type` 别名，而不是视图对外暴露的 `SearchFileMatches`/`SearchLineMatch` 接口。只有 type 别名可以赋值给 `presentationMeta` 返回的 `JsonValue` 索引签名；二者结构完全相同，因此投射出的值仍能读回为 `SearchResultView`。
+`packages/fs/tool-fs-search/src/presentation.ts` 拥有投影与收窄。`grepSearchMeta`/`globSearchMeta` 把 canonical 值投影为每个工具声明为 `output.presentationMeta` 的 `SearchMeta` 载荷；`presentGrepResult`/`presentGlobResult` 经 `searchViewFromMeta` 把 `result.meta` 读回。它们消费与面向模型渲染相同的已保留结果 —— `search-core.ts` 里的 `retainGrepMatches`/`retainGlobPaths` 只跑一次内联上限与每行预览预算，render 与投影都取这份产出 —— 所以文本与卡片对哪些结果幸存永不分歧，也没有第二次保留计算。`total` 是搜索找到的全部结果（截断前）；`truncated` 在上限丢弃了结果时置位。这是截断诚实点：模型看到的是被截断的内联结果加一个 spill 脚注，所以卡片不能把保留页当作完整结果 —— UI 读 `truncated`/`total` 显示截断指示，而非宣称模型从未有过的完整性。
 
-TUI（`packages/ui/tui/src/components/transcript.ts`）无需专用分支：它的结果视图 switch 显式处理 `terminal` 与 `diff`，并落到一个渲染 `view.content ?? this.result?.content` 的通用分支。因为 `SearchResultView` 以 `content` 携带了面向模型的文本，TUI 渲染出的仍是它此前已展示的同一段文本。渲染结构化 `files`/`paths` 形状的 web 前端是后续独立的 PR；本 PR 是后端契约及其两个生产者。
+**meta 有自己的字节预算。** 内联上限约束的是条目数，但一次宽泛搜索保留下来的匹配（数百条长行）仍可序列化到数百 KB，而 `meta` 会随会话日志持久化并在每次请求时重发。部署的最终输出预算（`dsh-spill-policy` 的 `maxInlineBytes`）只缩减结果的 `content` —— `PostToolDecision` 没有 `meta` 通道 —— 所以投影自己负责把 `meta` 约束住。`capMetaBytes` 丢弃末尾的文件组／路径，直到序列化 meta 装进 `searchMetaMaxBytes`（配置，默认 64 KiB），并把结果标记 `truncated`。单个大到自身都装不下的条目会被保留：不变量是可丢弃处一律有界，绝不产出隐藏了真实结果的空卡片。
 
-## Alternatives considered

-**单一扁平的 `SearchResultView` 接口，带可选的 `files?` 与 `paths?`。** 否决：它让两种形状相关字段在每个值上都成为可选，并允许一个畸形视图同时携带二者或都不携带。`kind` 区分符让每种形状的字段保持必填，并让消费方能穷尽分派。
+`SearchMeta` 的成员形状是对象字面量 `type` 别名，而非视图暴露的 `SearchFileMatches`/`SearchLineMatch` 接口，因为只有 type 别名可赋给 `presentationMeta` 返回的 `JsonValue` 索引签名；两者结构等价，所以投影值仍读回为 `SearchResultView`。
 
-**一个调用期的 `SearchCallView`，镜像 terminal 卡片两侧对称。** 否决：搜索调用在 `execute` 之前没有匹配或路径，视图只会携带 `GenericCallView` 已携带的标题。terminal 卡片的调用视图之所以配得上其标签，是因为命令、cwd 与描述在调用期就存在；而搜索的结构化内容不存在。
+TUI（`packages/ui/tui/src/components/transcript.ts`）不需要专门分支：它的结果视图 switch 显式处理 `terminal` 与 `diff`，`search` 视图落入同一个变暗的 generic body，从 `this.result?.content` 读取面向模型的文本。因为搜索视图不带自己的 `content`，而本 PR 之前 grep/glob 返回的是 generic 卡片，所以 TUI 输出与无 search 卡片的回退逐字节一致。渲染结构化 `files`/`paths` 形状的 web 前端是另一个后续 PR；本 PR 是后端契约及其两个生产者。
 
-**用一个专门的通道而非 `presentationMeta` 携带结构化结果。** 否决：规范值是执行局部的、绝不抵达客户端，而 `presentationMeta` 是既有的接缝，它把工具的 JSON 呈现 payload 随 `tool/result` 持久化并穿线回 `presentResult`。再加一条通道只会重复这条路径。

-## Consequences

-`grep` 与 `glob` 现在在每次非嵌套的成功调用上计算 `presentationMeta`，这是对已解析的匹配或路径做的一次有界投射。投射重新施加渲染已施加过的保留上限，因此每次调用会计算两遍保留集；输入受原始输出上限约束，故这不是新的伸缩性问题。
+**复用 `kind` 作形状判别子。** 否决：同一模块里调用视图上的 `kind` 已经表示 `ToolCallKind`（图标类别，取值含 `'search'`）。结果视图上再有一个含义不同的 `kind`，对任何同时持有两者的桥接层都会冲突。
 
-没有搜索卡片的 UI 渲染附上的 `content` 文本，因此没有消费方回退。渲染结构化形状的 web 消费方读取 `truncated`/`total` 与按文件分组；因为视图只携带保留的那一页，想要完整结果的 UI 沿面向模型文本里的 spill 定位符去取，与模型的做法完全一致。
+**把面向模型的文本作为视图的 `content` 附上。** 否决：对每个当前消费方是 no-op，且把整段搜索文本第二次序列化进持久化视图。视图是结构化形状；文本回退读原始结果内容。
 
-## Testing
+**在 `PostToolDecision` 上加 meta 通道，让 `dsh-spill-policy` 像约束 `content` 那样约束 `meta`。** 本 PR 否决：它为一个工具的载荷改动核心工具决策契约与 spill-policy 插件。投影在配置字节上限处约束自己的 `meta` 是自包含的，且保持 seam 不变。

-- [Canonical tool output contract](../architecture/2026-07-20-canonical-tool-output-contract.md) —— 本投射所乘的 value/render/`presentationMeta` 拆分；结构化值留在执行局部，卡片乘 `meta`。
-- [Web terminal card](2026-07-28-web-terminal-card.md) —— 本 PR 在后端所镜像的先例：工具把结果投射进 `presentationMeta` 与一个 `presentResult` 视图；搜索卡片的 web 消费方是类似的后续工作。
+`grep` 与 `glob` 现在在每次非嵌套的成功调用上计算 `presentationMeta`，这是对已保留匹配或路径的一次有界投影 —— 与 render 消费的是同一份保留产出，所以没有第二次保留计算，线上也没有翻倍的搜索文本。序列化 meta 受 `searchMetaMaxBytes` 约束，所以宽泛搜索不再把无界的结构化副本持久化进会话日志。
+
+无 search 卡片的 UI 渲染原始 `tool/result` 内容，所以没有消费方退化，TUI 也逐字节一致。渲染结构化形状的 web 消费方读 `truncated`/`total` 与按文件分组；因为视图只携带保留的、字节有界的页，想要完整结果的 UI 跟随面向模型文本里的 spill 定位符，与模型的做法完全一致。

 How a tool wants its call shown in a UI (an editor tool-call card, a CLI log line), provider-neutral so a tool describes itself without depending on any client protocol. `presentCall`/`presentResult` return a **`card`-tagged render intent** — a discriminated union a UI bridge switches on:

 `ToolCallKind` (`'read' | 'edit' | 'delete' | 'move' | 'search' | 'execute' | 'fetch' | 'other'`) picks an icon on a generic card. `FileLocation` (`{ path, line? }`) and `FileDiff` (`{ path, oldText, newText }`) are the shared file-card vocabulary. The design is pinned in [the render-intent-union Agent Note](../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md); the TUI and host/client runtime project this neutral vocabulary into their own views.

 - `ToolCallView`（待执行）：`{ card: 'generic', title, kind?, rawInput?, content?, locations? }`（默认卡片；`locations` 是 `{ path, line? }[]`，表示调用读取/修改的文件，供编辑器跟随）、`{ card: 'terminal', title, description?, cwd? }`（shell 命令→终端卡片）、或 `{ card: 'diff', title, diffs, locations? }`（文件创建/修改→行内 diff 卡片；`diffs` 是 `{ path, oldText, newText }[]`，新文件时 `oldText: null`）。

 Returning `undefined` selects generic fallback. Presenters depend only on their arguments and the durable result because UIs call them during live streaming and log replay. `output.presentationMeta(args, value)` derives JSON metadata for direct surface calls; that metadata persists with `tool/result` and returns to `presentResult`, while the canonical value itself remains execution-local and is never replayed. Nested Code dispatches do not compute metadata. `defineTool` soft-validates older logged arguments and falls back instead of crashing replay. `dsh-tool-bash` and `dsh-tool-fs` are the reference implementations; the [canonical-output Agent Note](../../../.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.md) owns the value/presentation split and the [render-intent Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md) owns card vocabulary.

Subject: [PATCH 094/278] fix(fs): persist read window offset in the read card
 meta

An empty read window (byte cap below the first selected line: `lines: []`
with `totalLines > 0`) dropped `offset` from the persisted presentation
meta, so a replayed read card could not report where the window starts or
where a continuation resumes. Carry `offset` on `FsReadMeta`,
`ReadResultView`, and the `presentationMeta` projection, and validate it in
`readMetaFromMeta` (1-based integer; the first line number may not fall
below it). Re-record the ACP fixtures and the cordis api catalog.

Also correct the Note's `parallel-file-reads` golden path
(examples/tui-agent -> apps/cli) and record the pre-card replay-degradation
tradeoff in the Decision section.

 Add a fourth `card` tag, `read`, to the [render-intent union](../architecture/2026-07-02-tool-render-intent-union.md) — result-side only. `ToolResultView` gains `ReadResultView { card: 'read'; title?; path; lines: ReadFileLine[]; totalLines; lang?; content? }`; `ReadFileLine { number; text }` is the shared line unit. `ToolCallView` is untouched: the pending state stays a `GenericCallView` (`kind: 'read'`) because a call carries no file content until `execute` returns, so there is nothing structured to show at call time. This diverges from the bash terminal card, which tags both sides — a terminal call already carries its command and cwd at call time, a read call carries neither content nor total, so tagging the call side would add an empty variant.
 
-The read tool projects the structured window through `output.presentationMeta`, the same persisted channel write/edit use for their applied-diff hunks ([canonical tool output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). `presentationMeta` runs once for a top-level surface call, returns `{ path, lines, totalLines, lang? }` as JSON the session validates and stores on the result's `meta`, and `presentResult` narrows that meta back into the `ReadResultView` on both live and replay paths. Without this channel the line array and total would be unreachable: the raw output object is not on the wire, and re-parsing the `N: text` text is lossy and fragile against the truncation footer.

The TUI's `renderBody` switch (`packages/ui/tui/src/components/transcript.ts`) is not `assertNever`-exhaustive: `terminal` and `diff` have arms and everything else falls through to the generic arm, which reads `view.content`. That default arm alone was not enough: `render()` sets `genericContent` — and with it the dim-Markdown `dimBody` treatment — on a separate gate that was `card === 'generic'` only, so a `read` card would have kept the text but lost its dim styling. The gate now admits `card: 'read'` too, taking `content` down the same dim-Markdown path, so a read renders in the TUI exactly as it did before the read card existed. Beyond that one gate the TUI needs no read-specific code.

A pre-card logged result — a valid read envelope with no persisted `meta`, recorded before this card existed — takes that same `undefined` path deliberately: the client falls back to the raw `result.content`, so it shows the enveloped `//` text rather than the envelope-stripped generic card the old presenter returned. This is the accepted degradation under the [pre-release stance](../../../CLAUDE.md): reject the old on-disk format rather than add an envelope-stripping compatibility branch, since this PR re-records every published fixture and the session format promises no backward compatibility.

 Tools optionally own pure `presentCall()` and `presentResult()` render intents, so UIs do not special-case tool names:
 
 - Call views are `{ card: 'generic', title, kind?, rawInput?, content?, locations? }`, `{ card: 'terminal', title, description?, cwd? }`, or `{ card: 'diff', title, diffs, locations? }`.
-- Result views are `{ card: 'generic', title?, content? }`, `{ card: 'terminal', title?, output?, exitCode?, signal? }`, `{ card: 'diff', title?, diffs }`, or `{ card: 'read', title?, path, lines, totalLines, lang?, content? }` (a completed file read → a line-numbered, optionally syntax-highlighted code view; `lines` is `{ number, text }[]` keeping each file line number, and `content` is the envelope-stripped text a UI without read support falls back to).
+- Result views are `{ card: 'generic', title?, content? }`, `{ card: 'terminal', title?, output?, exitCode?, signal? }`, `{ card: 'diff', title?, diffs }`, or `{ card: 'read', title?, path, offset, lines, totalLines, lang?, content? }` (a completed file read → a line-numbered, optionally syntax-highlighted code view; `offset` is the 1-based first line the window requested, kept even when `lines` is empty; `lines` is `{ number, text }[]` keeping each file line number, and `content` is the envelope-stripped text a UI without read support falls back to).
 
 Returning `undefined` selects generic fallback. Presenters depend only on their arguments and the durable result because UIs call them during live streaming and log replay. `output.presentationMeta(args, value)` derives JSON metadata for direct surface calls; that metadata persists with `tool/result` and returns to `presentResult`, while the canonical value itself remains execution-local and is never replayed. Nested Code dispatches do not compute metadata. `defineTool` soft-validates older logged arguments and falls back instead of crashing replay. `dsh-tool-bash` and `dsh-tool-fs` are the reference implementations; the [canonical-output Agent Note](../../../.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.md) owns the value/presentation split and the [render-intent Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md) owns card vocabulary.

-Enforcing backends register independently disposable `filesystem`, `bash`, or `terminal` family contributions with the policy owner. The section names only registered families in canonical order, and is empty without one. This is current need, not a future extension: the shipped headless inheritance composition combines sandboxed filesystem tools with unfenced one-shot bash, while the persistent-tools composition combines sandboxed filesystem tools and terminal commands without a sandboxed one-shot bash executor. A blanket statement would be false in both.

-The section states only facts shared by every enforcement dialect for each registered family. `read-only` says those operations cannot modify files. `workspace-write` states the canonical session workspace with non-exclusive wording and summarizes, without enumerating, that some platform temporary areas may also be writable. `danger-full-access` says the DSH file sandbox does not restrict those operations. Backend-selected temporary paths, `/dev/null`, runner readiness, and other policy domains are absent because `resolve()` cannot establish them at request assembly.
+The contribution states only facts shared by every enforcement dialect for each registered family. `read-only` says those operations cannot modify files in the standing mode. Tool owners separately register a family only when their real schema and execution path offer an approved wider retry; the read-only text adds anti-refusal guidance only for the intersection of enforced and escalatable families. `workspace-write` states the canonical session workspace with non-exclusive wording and summarizes, without enumerating, that some platform temporary areas may also be writable. `danger-full-access` says the DSH file sandbox does not restrict those operations. Backend-selected temporary paths, `/dev/null`, runner readiness, and other policy domains are absent because `resolve()` cannot establish them at request assembly.
 
-The provider runs during normal request assembly, after a `/permission` switch has committed its existing `sandbox/mode` event and before `request/header` is logged. The rendered system text is therefore the durable reconstruction of the exact model-visible fact. Repeated assemblies over unchanged session state produce identical bytes; resume and replay fold the same durable mode event and immutable `SessionHeader.cwd` without catch-up state.
+The existing `dsh-system-prompt` assembly now has ordered dynamic contexts alongside stable system sections and tool schemas. After assembling one step, agent-loop renders all active contexts as one full snapshot with an explicit supersession statement. It appends a sourced `user/message` only when no retained snapshot exists, the bytes changed, compaction removed the retained message, or the final contribution disappeared and needs one clearing snapshot. The snapshot is appended after existing history and before `step/start`, so a changed policy preserves the preceding system-and-conversation cache prefix. The session event itself reconstructs the exact model input; `request/header` remains byte-identical when only policy context changes.
 
-Ownership stays narrow. Approval policy remains the separate `approval:policy` section, plan mode remains `plan:policy`, and tool plugins continue to own schemas plus attempt, denial, and escalation guidance. The prompt states standing policy; filesystem, one-shot bash, and terminal backends remain the enforcement boundaries.
+Ownership stays narrow. Approval policy contributes its complete current `ask` or `never` fact to the same full snapshot; migrating sandbox alone would not preserve cache because `/permission` changes both owners. Plan mode remains `plan:policy`, and tool plugins continue to own schemas plus attempt, denial, and escalation guidance. Context states standing policy; filesystem, one-shot bash, and terminal backends remain the enforcement boundaries.
+
+The cache decision follows current source rather than analogy alone. Codex models permissions as a developer-role `WorldState` section with a persisted fingerprint, emits it only when state changes or retained history lost the fragment, and records the snapshot transition. Hermes keeps its system prompt fixed for a session and explicitly prepends changing skill, model, and voice notices to the next user message to avoid invalidating prompt cache. Pi has no comparable built-in sandbox state, and Claude Code's current native implementation is not publicly inspectable; Anthropic's public cache guidance nevertheless places changing per-request context after the stable cached prefix.
+
+The earlier real-provider Web fixture quantified the defect in the system-section version. The first `danger-full-access` and `workspace-write` requests each reported only 256 cache-read tokens against 14,691 and 14,782 uncached input tokens. Later steps under an unchanged policy reported approximately 14.7k–15.5k cache-read tokens. Moving only the sandbox sentence would not fix those misses because the same preset switch also rewrote the approval-policy system section.

 The positive control therefore failed the pre-registered sensitivity gate. Candidate A and B were not run, and this experiment does not select or validate the current wording. It instead establishes that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
 
+The cache-safe delivery rework then supplied a separate, non-statistical acceptance comparison over the neutral Web task `Create the relative path policy-neutral.txt ...`; it does not replace the pre-registered twelve-session experiment. Candidate A's categorical read-only statement produced a text refusal with zero tool calls. Candidate B added one composition-conditioned sentence only for enforced families whose tools expose escalation. A fresh real-provider run then issued an ordinary `write`, observed the read-only denial, retried the same operation in the same turn with `sandbox_permissions: "workspace-write"`, received approval, read the file back, and verified the exact contents. It made no speculative escalation. Across the permission switches and four mutation steps, cache reads were 14,848–15,872 tokens while uncached input was 59–251 tokens per request, directly demonstrating the stable-prefix benefit.
+
 ## Alternatives considered
 
 **Narrate only mode changes.** Rejected because it leaves a fresh session uninformed and makes the first denied operation the policy-discovery mechanism. It also requires a baseline definition that is unnecessary when current state can be rendered directly.
 
 **Scan denial history or remember the last narrated mode.** Rejected because denial events describe attempted operations, not authoritative current state, while process-local bookkeeping does not survive resume. The owner can fold the durable policy directly on every request.
 
-**A generic runtime-facts registry.** Rejected because the existing system-prompt registry already evaluates owner-provided sections with the live agent at request time. One policy owner has no cross-domain invariant that justifies another package or registry.
+**Put current policy in a dynamic system section.** Rejected after real provider evidence showed that a first-time permission switch reduced cache reads to 256 tokens while roughly 14.7k input tokens missed. DeepSeek matches complete prefixes; changing the first wire message prevents reuse of the longer system-plus-history prefix.
 
-**Repeat tool schemas or approval and plan guidance in the section.** Rejected because those surfaces already have owners and independent lifecycles. Duplicating them would create contradictory request prefixes and broaden invalidation.
+**Call `agent.inject()` independently from each policy owner.** Rejected because sibling listener order would define model order, separate messages could expose mismatched intermediate snapshots, and every owner would need its own compaction-retention scan. The existing assembly owner can order contributions and materialize one atomic full snapshot.
+
+**A generic runtime-facts package.** Rejected because the existing system-prompt assembly already owns sections, schemas, variables, scope, and the authoritative per-step waterfall. Extending that owner with ordered contexts adds no package or second registry service.
+
+**Repeat tool schemas or plan guidance in the context.** Rejected because those surfaces already have owners and independent lifecycles. Approval current state joins the snapshot only because the same `/permission` switch changes it and leaving its system section would retain the cache defect.
+
+**Keep Candidate A after the cache-safe move.** Rejected by the neutral real-provider task: the model returned a pure text refusal and made no tool call despite the existing bash attempt guidance. Candidate B states no escalation mechanics itself; it tells only families whose tools actually advertise a wider retry not to infer impossibility from the standing label, then delegates denial and escalation behavior back to those tool owners.
 
 **Keep sandbox mode absent because a standing mode label once caused preemptive refusal.** Rejected because a fresh Web request otherwise exposes mutation tools while withholding their standing policy, producing false capability claims before the first operation. The earlier live measurement remains a required counter-test: five of twelve turns ended without a tool call under `Bash commands run under the "read-only" file sandbox.` The committed tool-owned attempt guidance postdates that measurement, so the replacement is selected through a new positive-control experiment under the current tool contract rather than assuming the old and current conditions match.
 
-**A separate model-context package.** Rejected because Cordis services can observe current runtime contributions directly, while approval and plan policy sections already live with their owners. A new package would add a shallow composition seam and documentation/gate surface for one internal adapter.
+**A separate model-context package.** Rejected because Cordis services can observe current runtime contributions directly and the existing assembly service can order them. A new package would add a shallow composition seam and documentation/gate surface around the same request boundary.
 
 **Enumerate writable temporary roots.** Rejected because the backend is selected later at `confine()`: bwrap, Landlock, Seatbelt, and the in-process filesystem fence do not grant one common temporary-path set. Host-specific paths in a standing request would be both unstable and overclaimed.
 
 ## Consequences
 
-A model can answer what registered file operations the standing mode governs before probing a tool, and the next request after `/permission` reflects the committed mode. This adds a small dynamic system section and intentionally invalidates the request prefix when policy or enforcing-family composition changes; unchanged state remains cache-stable. The statement is guidance, not an enforcement guard: runtime safety still comes from the registered filesystem, one-shot bash, and terminal backends consuming the same resolved policy.
+A model can answer what registered file operations the standing mode governs before probing a tool, and the next request after `/permission` reflects the committed mode. The stable system prompt no longer changes for sandbox or approval state; a changed full context snapshot is append-only after retained history, and unchanged state adds no message. Older snapshots remain in history but are explicitly superseded by the latest full snapshot. The statement is guidance, not an enforcement guard: runtime safety still comes from the registered filesystem, one-shot bash, and terminal backends consuming the same resolved policy.
 
-Focused tests pin all modes, family combinations, contribution disposal, canonical roots, switch timing, and byte stability across different `TMPDIR` values. Keyless assembled snapshots pin the request header through real Loader compositions, including all three families. Keyless replay owns the neutral denial-to-escalation trajectory; it is a structural regression proof, not wording-selection evidence.

+现有 `dsh-system-prompt` 组装在稳定系统段与工具 schema 之外，还包含有序的动态上下文。组装一个步骤后，agent loop（智能体循环）会将所有活动上下文渲染成一份带显式取代声明的完整快照。仅当不存在保留快照、字节发生变化、压缩（compaction）移除了保留消息，或最后一项贡献消失而需要一份清除快照时，它才会追加一条带来源的 `user/message`。快照追加在现有历史之后、`step/start` 之前，因此策略变化时仍会保留此前的系统与对话缓存前缀。会话事件本身可以重建确切的模型输入；只有策略上下文变化时，`request/header` 仍逐字节相同。

 ## 曾考虑的替代方案
 
 **仅叙述模式变更。** 不予采用，因为这会让新会话不了解策略，并把首次被拒绝的操作变成策略发现机制。如果可以直接渲染当前状态，也就无需额外定义基线。
 
 **扫描拒绝历史或记住上次叙述的模式。** 不予采用，因为拒绝事件描述的是尝试过的操作，而不是权威的当前状态；进程本地的簿记也无法跨恢复保留。归属方可以在每次请求时直接折叠持久策略。
 
-**通用运行时事实注册表。** 不予采用，因为现有系统提示词注册表已经会在请求时使用当前 agent 评估归属方提供的段落。单一策略归属方不存在需要另一个包或注册表来承载的跨领域不变式。
+**把当前策略放入动态系统段。** 不予采用，因为真实提供方证据显示，首次权限切换后缓存读取降至 256 个 token，而约 14.7k 个输入 token 未命中缓存。DeepSeek 匹配完整前缀；改变第一条 wire 消息会阻止复用更长的系统与历史前缀。
 
-**在该段落中重复工具 schema，或批准与计划引导。** 不予采用，因为这些接口已有各自归属方和独立生命周期。重复内容会造成相互矛盾的请求前缀，并扩大缓存失效范围。
+**由每个策略归属方独立调用 `agent.inject()`。** 不予采用，因为同级监听器的顺序会决定模型所见顺序，分开的消息可能暴露不匹配的中间快照，并且每个归属方都需要各自扫描压缩后的保留状态。现有组装归属方可以对贡献排序，并具体化一份原子化的完整快照。
+
+**通用运行时事实包。** 不予采用，因为现有系统提示词组装已经拥有段、schema、变量、作用域和权威的逐步骤 waterfall（瀑布式事件）。为该归属方增加有序上下文，无需新增包或第二个注册表服务。
+
+**在上下文中重复工具 schema 或计划引导。** 不予采用，因为这些接口已有各自归属方和独立生命周期。批准的当前状态加入快照，仅仅是因为同一个 `/permission` 切换会改变它，而把它留在系统段会保留缓存缺陷。
+
+**缓存安全迁移后仍保留 Candidate A。** 不予采用，因为中性的真实提供方任务中，尽管已有 bash 尝试引导，模型仍以纯文本拒绝，且没有调用工具。Candidate B 本身不说明任何升权机制；它只针对那些工具确实公开更宽松模式重试的家族，说明不能从常驻标签推断操作不可能完成，然后把拒绝与升权行为交还给这些工具归属方。
 
 **继续省略沙箱模式，因为常驻模式标签曾引发预防性拒绝。** 不予采用，因为新的 Web 请求否则会暴露变更工具，却隐去这些工具的常驻策略，导致模型在首次操作前错误声称自身能力。先前的线上测量仍是必须执行的反证测试：使用 `Bash commands run under the "read-only" file sandbox.` 时，十二个轮次中有五个没有调用工具。已提交的工具归属方尝试引导晚于该测量，因此应通过当前工具契约下的新阳性对照实验选择替代文案，而不能假设旧条件与当前条件相同。
 
-**独立的模型上下文包。** 不予采用，因为 Cordis 服务可以直接观察当前运行时贡献，而批准与计划策略段落也已经与各自归属方放在一起。新包会为了一个内部适配器引入浅层组合 seam 和额外的文档／门禁表面。

 ## 后果
 
-模型可以在试探工具前回答常驻模式管辖哪些已注册文件操作，且 `/permission` 后的下一个请求会反映已提交的模式。这会增加一个小型动态系统段落，并在策略或强制执行家族组合变化时有意使请求前缀缓存失效；状态不变时仍保持缓存稳定。该声明是引导，而不是强制执行护栏：运行时安全仍来自已注册的文件系统、一次性 bash 与终端后端消费同一项解析完成的策略。

The `never` policy is enforced inside the service before waterfall dispatch, so even an answerer registered later with `prepend` cannot bypass it. Answerers return an outcome when they own the request or call `next()` to delegate; the first answer occupies the single decision slot.

Model-visible behavior is the caller's derived tool result, while the request header records the prompt policy that the model actually saw.

 Escalating bash calls resolve `ctx.approval` before execution. `allowed-once` applies the requested mode only to that call; rejection, cancellation, unavailability, or missing approval context executes nothing and returns a distinct error. On a real denial, the model may retry the same command once in the same turn with the narrowest sufficient mode and justification; the approval prompt itself is the consent step. Escalation is never speculative, and a disabled or rejected approval is final. The [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) owns the rationale.
 
+When the executor confines and the schema exposes escalation, this plugin registers the `bash` family as escalatable with `ctx.sandboxPolicy`. The policy owner can therefore add anti-refusal context only when the actual bash tool offers the denial-and-approved-retry path; the contribution disposes with the plugin.

 ## Per-session mode switching
 
-For sandboxing executors, each call resolves mode as one-shot escalation, then session override, then executor default. Non-sandboxing and agent-less calls carry no session override. Neither the prompt nor a switch notice announces the standing mode; denial results report the effective mode when the boundary matters.

 - `ctx.systemPrompt.section(section: PromptSection): () => void` Contribute a section. The layer is the calling context's scope: `agent.ctx` contributes to that agent alone, shadowing a same-named global section there. Duplicate names within one layer and non-finite orders throw. Disposed with the calling fiber.
+- `ctx.systemPrompt.context(context: PromptContext): () => void` Contribute cache-safe dynamic model context. Contexts are ordered independently from system sections; scoped contributions shadow same-named globals. The agent loop materializes the complete current set as one sourced user-role snapshot after retained history, only when changed or missing. Duplicate names within one layer and non-finite orders throw. Disposed with the calling fiber.
 - `ctx.systemPrompt.tools(provider: (context: AssembleContext) => ToolProviderResult): () => void` Contribute tool schemas, evaluated at each assembly with that assembly's context. `ToolProviderResult` = `{ schemas, knownNames? }`: `schemas` is the post-restriction visible set; `knownNames` is the pre-restriction universe used by `toolOrder`. A provider must not return a schema named `TOOL_ORDER_REST`. Scoped providers are consulted only for their scope's assemblies. Disposed with the calling fiber.
 - `ctx.systemPrompt.variable(name: string, provider: (context) => string | undefined): () => void` Contribute a prompt variable, referenced from section text as `{{name}}`. Scoped variables shadow a same-named global for that agent. Duplicate-in-layer or unreferenceable names throw; `undefined` means "no value for this assembly". Disposed with the calling fiber.
 - `ctx.systemPrompt.assemble(context?: AssembleContext): Promise` Assemble the prompt for one caller: the global layer merged with `context.scope`'s layer, with tool schemas detached before the transform seam. Runs through the scope-filtered `system-prompt/assemble` waterfall and returns its authoritative result. An optional `context.signal` explicitly controls this assembly request; providers and listeners may cooperate with it but must not retain it for another turn. Rejects when a configured `toolOrder` names a tool outside the providers' `knownNames` universe, or when a provider returns the reserved rest-entry name.

 - `AssembleContext` — what one `assemble()` call is FOR. Merge-extensible; declares `scope?: ScopeKey` (the layer selector) and `signal?: AbortSignal` (the explicit request control capability) here, while `dsh-agent` declares `agent?: Agent` (the typed DX field — never set without `scope`; use `assembleContextFor(agent, signal)`). Providers must tolerate absent fields because a bare `assemble()` carries an empty, scope-less, signal-less context. `signal` is a request value, not part of the ambient Agent execution frame.
 - `PromptSection` — `{ name, order, text }`. Sections are concatenated in ascending `order`. Order bands: `-100` is the harness identity, `0` the deployment persona, tool guidance uses `100–199`.
-- `PromptAssembly` — `{ sections: AssembledSection[], tools: ToolSchema[], variables: Record }`. Section texts arrive resolved but not yet interpolated; `variables` holds every registered variable resolved against the context. Tool schemas are part of the assembly by design: "what the model is told it can do" is one coherent thing, even though adapters transmit schemas as a separate wire field.
+- `PromptContext` — `{ name, order, text }`. Contexts carry changing current facts that must not rewrite the cached system/history prefix; they use the same per-assembly provider and strict-variable contracts as sections.

Tool schemas are part of the assembly by design: "what the model is told it can do" is one coherent thing, even though adapters transmit schemas as a separate wire field.
 - `renderPrompt(assembly)` — interpolates `{{variable}}` references in each section, drops empty sections, joins with blank lines. STRICT: an unknown reference (`Object.hasOwn` lookup — prototype names like `{{constructor}}` are unknown), a registered-but-valueless reference, a malformed complete `{{…}}` group, or a `{{` that opens no complete group while a `}}` still follows (`{{{model}}}`) throws — fail loud beats shipping a malformed prompt. A lone `{{` with no `}}` anywhere after it passes through verbatim; substituted values are never re-scanned.
+- `renderContextSnapshot(assembly)` — applies the same strict interpolation to contexts, drops empty entries, and emits one full snapshot with an explicit supersession statement. An empty active set returns `''`; the loop emits one clearing snapshot when previously visible context disappears.
 
 Merge-extensible: plugins can declare extra fields on `PromptAssembly` and `AssembleContext` via declaration merging.
 
 ### Extension points
 
 - Section providers: tool packages own their cross-call guidance (`tool:bash`, `tool:read`, …); this plugin owns `harness:identity` and `deployment:persona`.
+- Context providers: policy and other changing-state owners contribute complete current facts without mutating the stable system prompt.
 - Variable providers: the agent loop registers `model` and `cwd`; any plugin can register the facts it owns (a future `date`, git state, …).
 - Tool schema providers: `ToolRegistry` registers itself as a tool provider automatically.
 - The [`system-prompt/assemble` waterfall](#live-events): cooperatively mutate or replace the assembly per caller.

+### Dynamic runtime context
+
+#### What the model sees
+
+Active contexts are joined in deterministic order after strict interpolation and logged as one sourced user-role message immediately before the request that first needs that snapshot. The message begins `Current runtime context. This snapshot supersedes earlier runtime-context snapshots.` A changed snapshot is appended after retained history; an unchanged retained snapshot adds nothing. If compaction removes it, the current full snapshot is emitted again. Removing the last context emits one explicit clearing snapshot.
+
+#### Token effect
+
+One concise message on the first request, on an effective context change, after compaction removed the retained snapshot, or when the active set becomes empty. Unchanged steps add no duplicate tokens.
+
+#### KV Cache effect
+
+Append-only after retained history. A context change preserves the previously cached system and conversation prefix instead of rewriting the first wire message.

 The tool passes `exec` (the tool-execution context) as the opaque `actor` on every dispatch. The default thunks return `undefined` (the unconstrained bare provider). When `@deepseek-ai/dsh-fs-policy` is loaded it occupies the single decision slot — returning `createIfAbsent`/`replaceIfVersion`/`{ version }` or throwing `FS_NOT_OBSERVED` — and records on `fs/observed`. Backend errors (`FsError`) and a thrown `FS_NOT_OBSERVED` flow through `ToolRegistry.execute()` and become `isError` tool results with their `{ name, code }` attached.

The policy owner therefore adds anti-refusal context only while the real mutation tools offer that path.

 `fs/observed` fires AFTER the read/write/edit already succeeded, via a plain `ctx.emit`. A listener is contractually a synchronous, side-effect-only recorder (`@deepseek-ai/dsh-fs-policy`'s is a `WeakMap.set`); the tool does not guard the emit, so a listener that throws would surface as the tool's `isError` result — async or fallible observation does not belong on this event.

 工具在每次分派中把 `exec`（工具执行上下文）作为不透明 `actor` 传入。默认 thunk 返回 `undefined`（不受约束的裸提供方）。加载 `@deepseek-ai/dsh-fs-policy` 后，它会占用单个决策槽：返回 `createIfAbsent`/`replaceIfVersion`/`{ version }` 或抛出 `FS_NOT_OBSERVED`，并在 `fs/observed` 时记录。后端错误（`FsError`）和抛出的 `FS_NOT_OBSERVED` 会流经 `ToolRegistry.execute()`，变成 `isError` 工具结果，并附带 `{ name, code }`。
 
+当 `ctx.fs.sandboxMode` 表明提供方施加沙箱限制时，write/edit 会公开 `sandbox_permissions` 与 `justification`，通过 `ctx.approval` 解析经批准的重试，并将 `filesystem` 家族注册到 `ctx.sandboxPolicy`，标记为可升权。因此，策略归属方只会在实际变更工具提供该路径时添加反预防性拒绝上下文。
+
 ## `fs/observed` 发后即忘
 
 `fs/observed` 在读取/写入/编辑已经成功之后，通过普通 `ctx.emit` 发出。监听器的契约是同步且只有副作用的记录器（`@deepseek-ai/dsh-fs-policy` 使用 `WeakMap.set`）；工具不保护这次发出，因此监听器抛出会作为工具的 `isError` 结果出现。异步或可能失败的观察不属于该事件。

+The stable system prompt remains byte-identical across mode changes. A changed full context snapshot is appended after retained history, preserving the prior cached prefix; subsequent unchanged requests reuse that retained snapshot.
 
 ## Known Limitations and Deferred Work
 
 - **One primary workspace root per session** — policy resolves `SessionHeader.cwd`; extra writable roots are not part of `SandboxExecutionPolicy`.
 - **File-effect modes only** — `SandboxMode` governs file effects; network and process policy are outside its vocabulary, so no knob here restricts them.

+`ApprovalPolicy` is `'ask'` or `'never'`. The effective value is the last `approval/policy` event, falling back to config; `setApprovalPolicy()` is the write path. `'never'` rejects before interactive dispatch. Both policies contribute their complete current meaning to the cache-safe runtime-context snapshot.
 
 The tools pipeline routes `ask` decisions through this seam and fails closed when it is absent; the sandboxed bash tool also uses it for escalated retries. The ACP automation bridge answers calls for its own agents through the client's machine policy. Audit events remain log-only, so the model sees only the asking consumer's result. See the [approval-seam Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-approval-seam.md) and [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md).
 
 ## Model Experience
 
-### System prompt and policy notice
+### Current approval policy context
 
 #### What the model sees
 
-Under `ask`, every agent request carries the ask-policy prompt section below. Under `never`, it carries the never-policy prompt section below. A policy switch injects exactly `The approval policy changed from "" to "" (changed by the user).` or `The approval policy changed from "" to "" (changed by the operator/config).` before the next step.
+The first request and each effective policy change append a full runtime-context snapshot after retained history. Under `ask`, the approval contribution states that configured answerers may be consulted and absence fails closed. Under `never`, it states the deterministic rejection and non-escalation consequence. Unchanged requests retain the earlier snapshot without adding another message.
 
-##### Ask-policy prompt section
+##### Ask-policy contribution
 
 ```markdown
-
+Approval policy: ask. Operations that require approval may ask through the configured answerers; without an available answerer, the request fails closed.
 ```
 
-##### Never-policy prompt section
+##### Never-policy contribution
 
 ```markdown
 Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
 ```
 
 #### Token effect
 
-Small fixed per-request cost, larger under `never`; a change notice is conditional and retained in history.
+One concise context message on the first request and on an effective change; unchanged requests add no duplicate policy tokens.
 
 #### KV Cache effect
 
-Prefix-stable while the approval policy is unchanged. An `ask`/`never` switch changes the system-prompt section and invalidates reuse from its first changed token; the accompanying notice is append-only.
+Append-only after retained history. An `ask`/`never` switch preserves the stable system and conversation prefix instead of rewriting the first wire message.

 工具流水线通过此 seam 路由 `ask` 决定，并在该 seam 缺失时以拒绝方式关闭；沙箱 bash 工具也会将它用于升权重试。ACP 自动化桥接层根据客户端的机器策略，回答其自有 agent 的调用。审计事件仍只写入日志，因此模型只会看到发起请求的消费方所返回的结果。详见[审批 seam Agent Note（agent 决策记录）](../../../.agents/notes/implemented/feature/2026-07-06-approval-seam.md)和[沙箱 Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md)。
 
 ## 模型体验
 
-### 系统提示词与策略通知
+### 当前审批策略上下文
 
 #### 模型看到的内容
 
-在 `ask` 下，每个 agent 请求都会携带下方的 ask 策略提示词段。在 `never` 下，请求会携带下方的 never 策略提示词段。策略切换会在下一步骤前精确注入 `The approval policy changed from "" to "" (changed by the user).` 或 `The approval policy changed from "" to "" (changed by the operator/config).`。
+首次请求和有效策略每次变化时，都会在保留的历史后追加一份完整运行时上下文快照。在 `ask` 下，批准贡献会说明可咨询已配置的应答者，缺少应答者时以拒绝方式关闭。在 `never` 下，它会说明确定性的拒绝与非升权后果。未变化的请求会保留先前快照，不增加另一条消息。
 
-##### Ask 策略提示词段
+##### Ask 策略贡献

-
+Approval policy: ask. Operations that require approval may ask through the configured answerers; without an available answerer, the request fails closed.

-##### Never 策略提示词段
+##### Never 策略贡献
 
 ```markdown
 Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).

 ```
 
 #### Token 影响
 
-每个请求有少量固定成本，`never` 下的成本更高；变更通知按条件出现，并保留在历史中。
+首次请求和策略实际变化时增加一条简洁的上下文消息；未变化的请求不增加重复的策略 token。
 
 #### KV Cache 影响
 
-审批策略不变时，前缀保持稳定。`ask`／`never` 切换会改变系统提示词段，并从首个变化的 token 开始使复用失效；随附通知只会追加。
+在保留的历史之后仅追加。`ask`／`never` 切换会保留稳定的系统与对话前缀，而不会改写第一条 wire 消息。

 The wording experiment pre-registered preemptive refusal as its primary endpoint and required the old standing sentence to produce at least one refusal in twelve fresh sessions before any replacement could be judged. On 2026-07-30, commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` ran `deepseek-v4-flash` through the shipped Web composition with the exact positive-control sentence `Bash commands run under the "read-only" file sandbox.` and the current tool-owned attempt guidance. The control produced zero preemptive refusals and zero speculative escalations; all twelve sessions made an ordinary bash call, observed a denial, escalated in the same turn, received approval, and landed the requested file. No sample was excluded.
 
-The positive control therefore failed the pre-registered sensitivity gate. Candidate A and B were not run, and this experiment does not select or validate the current wording. It instead establishes that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
+After the cache-safe delivery change, commit `10d4e0ff7b68d38fc4403403b644aac442b97a00` repeated the same twelve-session positive control through the new tail-context channel. It again produced zero preemptive refusals and zero speculative escalations; all twelve sessions made an ordinary first call, observed denial, escalated in the same turn, and received approval. Eight landed the exact requested file, and no sample was excluded.

+Both positive controls therefore failed the pre-registered sensitivity gate. The formal twelve-session Candidate A and B arms were not run, and these experiments do not select or validate the current wording. They establish that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
 
 The cache-safe delivery rework then supplied a separate, non-statistical acceptance comparison over the neutral Web task `Create the relative path policy-neutral.txt ...`; it does not replace the pre-registered twelve-session experiment. Candidate A's categorical read-only statement produced a text refusal with zero tool calls. Candidate B added one composition-conditioned sentence only for enforced families whose tools expose escalation. A fresh real-provider run then issued an ordinary `write`, observed the read-only denial, retried the same operation in the same turn with `sandbox_permissions: "workspace-write"`, received approval, read the file back, and verified the exact contents. It made no speculative escalation. Across the permission switches and four mutation steps, cache reads were 14,848–15,872 tokens while uncached input was 59–251 tokens per request, directly demonstrating the stable-prefix benefit.

 措辞实验预先登记「预防性拒绝」为主要终点，并要求旧常驻句子在十二个 fresh session 中至少产生一次拒绝，之后才能评判任何替代措辞。2026-07-30，commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` 通过已交付的 Web 组合运行 `deepseek-v4-flash`，使用精确的阳性对照句子 `Bash commands run under the "read-only" file sandbox.` 与当前工具归属方的尝试引导。对照组产生零次预防性拒绝和零次推测性升级；十二个会话全部先发起普通 bash 调用、观察到拒绝、在同一轮次升级、获得批准，并让所请求文件实际落盘。没有样本被排除。
 
-因此，阳性对照未通过预先登记的灵敏度门槛。Candidate A 与 B 均未运行，本实验不选择也不验证当前措辞。它只说明先前十二次中五次的结果无法在本任务与当前工具引导下复现；在声明模型行为率之前，需要更强的阳性对照或不同的任务分布。下述确定性测试只证明请求构造与回放真实一致。
+缓存安全交付变更后，commit `10d4e0ff7b68d38fc4403403b644aac442b97a00` 通过新的尾部上下文通道重复了同一项十二会话阳性对照。结果再次为零次预防性拒绝和零次推测性升权；十二个会话的首次调用均为普通调用，随后观察到拒绝、在同一轮次升权并获得批准。其中八个会话让所请求文件按确切要求落盘，没有样本被排除。

+因此，两项阳性对照均未通过预先登记的灵敏度门槛。Candidate A 与 B 的正式十二会话实验组均未运行，这些实验不选择也不验证当前措辞。它们说明先前十二次中五次的结果无法在本任务与当前工具引导下复现；在声明模型行为率之前，需要更强的阳性对照或不同的任务分布。下述确定性测试只证明请求构造与回放真实一致。
 
 随后，缓存安全交付重做针对中性 Web 任务 `Create the relative path policy-neutral.txt ...` 提供了一次独立的非统计验收对比；它不取代预先登记的十二会话实验。Candidate A 的绝对化只读声明导致模型以纯文本拒绝，工具调用为零。Candidate B 只针对受强制执行、且其工具公开升权能力的家族增加一句按组合条件化的文案。随后一次全新的真实提供方运行先发出普通 `write`，观察到只读拒绝，再在同一轮次用 `sandbox_permissions: "workspace-write"` 重试同一操作，获得批准、读回文件并核验确切内容。它没有进行推测性升权。在权限切换和四个变更步骤中，每个请求的缓存读取为 14,848–15,872 个 token，未缓存输入为 59–251 个 token，直接证明了稳定前缀的收益。

The following skills are available in this session:\n\n\n- `15-05-premortem`: Use before starting risky work — rebases, large refactors, multi-file migrations, or deploys — to identify failure modes and mitigations in advance.\n- `acceptance-criteria`: 检查Acceptance Criteria格式和完整性，验证是否符合Given-When-Then结构、覆盖正常流程/边界条件/异常场景。适合在为User Story编写AC后、准备测试用例前使用，当需要验收AC质量时。帮助不熟悉BDD的PM/BA确保AC明确、可测试、覆盖完整，避免遗漏关键场景。\n- `agents-sdk`: Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `aico-pm-user-story-writing`: Transform requirements into well-structured User Stories using \"As a [user], I want [goal], So that [benefit]\" format with Given/When/Then acceptance criteria. Use this skill when: - User asks to \"write user story\", \"create story\", \"add story\" - User mentions \"user story\", \"backlog item\", \"story\" - Running /pm.plan and need to break PRD into implementable stories - Creating backlog items for development team - Need to formalize a requirement into standard story format - Converting feature req...\n- `algorithmic-art`: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.\n- `animation-vocabulary`: Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term (\"the bouncy thing when a popover opens\" → Pop in; \"the iOS rubber-band scroll\" → Rubber-banding). Use when the user asks \"what's it called when…\", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.\n- `app-comprehensive-test-generator`: Generate exhaustive user-flow and edge-case test scenarios from an app's codebase, produce scenario .md files, execute tests using connected or newly created MCPs, and produce an app.qa.report.md summarizing failures and suggested fixes.\n- `apple-design`: Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.\n- `brainstorming`: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- `brand-guidelines`: Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.\n- `canvas-design`: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.\n- `claude-api`: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answ...\n- `cloudflare`: Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), feature flags (Flagship), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `cloudflare-email-service`: Send and receive transactional emails with Cloudflare Email Service (Email Sending + Email Routing). Use when building email sending (Workers binding or REST API), email routing, Agents SDK email handling, or integrating email into any app — Workers, Node.js, Python, Go, etc. Also use for email deliverability, SPF/DKIM/DMARC, wrangler email setup, MCP email tools, or when a coding agent needs to send emails. Even for simple requests like \"add email to my Worker\" — this skill has critical conf...\n- `cloudflare-one`: Guides Cloudflare One Zero Trust and SASE work across Access, Gateway, WARP, Tunnel, Cloudflare WAN, DLP, CASB, device posture, and identity. Use when designing, configuring, troubleshooting, or reviewing Cloudflare One deployments. Retrieval-first: use current Cloudflare docs/API schemas instead of embedded product docs.\n- `cloudflare-one-migrations`: Plans migrations from Zscaler ZIA/ZPA, Palo Alto, legacy VPN, SWG, or SASE stacks to Cloudflare One. Use for migration assessments, policy mapping, rollout plans, and parity/gap analysis.\n- `code-review`: Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- `codebase-design`: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.\n- `content-refiner`: Refine verbose educational content by eliminating redundancy, tightening prose, and strengthening lesson connections. Use when content is wordy, repetitive, or lacks narrative flow between sections.\n- `context-compression`: This skill should be used when long-running agent sessions need context compression, structured summarization, compaction, token-per-task optimization, or durable handoff summaries that preserve decisions, files, risks, and next actions.\n- `create-feishu-doc`: Create a Feishu document and grant edit permissions to the user. Use when asked to write content to Feishu or create a document in a wiki space.\n- `design-compass`: Use when doing any product or UI design work — brainstorming a feature, starting a visual/interaction direction, reviewing half-built UI, or final-checking before ship; also when unsure which design skill applies. 产品设计 / 界面设计 / 交互设计 / UI review / 脑暴 / 视觉方向 / 设计验收时使用。\n- `diagnosing-bugs`: Diagnosis loop for hard bugs and performance regressions. Use when the user says \"diagnose\"/\"debug this\", or reports something broken/throwing/failing/slow.\n- `doc-coauthoring`: Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.\n- `docx`: Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. When Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks\n- `domain-modeling`: Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.\n- `durable-objects`: Create and review Cloudflare Durable Objects. Use when building stateful coordination (chat rooms, multiplayer games, booking systems), implementing RPC methods, SQLite storage, alarms, WebSockets, or reviewing DO code for best practices. Covers Workers integration, wrangler config, and testing with Vitest. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `ego-browser`: ego-browser (ego-lite) is a Chromium-based browser designed from the ground up to be friendly to both human users and AI Agents. AI Agents work in their own isolated space, reusing the user's login state without competing for the browser. Use this skill whenever the user needs to interact with a website opening pages, filling forms, clicking buttons, taking screenshots, extracting page data, testing web apps, logging into sites, automating browser operations, or any other browser automation t...\n- `emil-design-eng`: This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great.\n- `feishu-workflow`: 飞书文档全流程管理 — 搜索、创建、编辑 wiki 文档，支持内容排版、表格、代码块、白板\n- `find-animation-opportunities`: Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; it proposes motion with exact values, it does not implement it. Use when the user asks \"what could be animated here?\" or wants to \"make this feel more alive\". For fixing existing animations, use improve-animations or review-animations instead.\n- `frontend-design`: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- `gap-to-topic`: Turn a research area into a go/no-go decision dossier for ONE candidate thesis/proposal topic — a 3-gate verdict (is the gap open? is it a contribution? is it feasible?) with the evidence laid out so the researcher can verify it. Use when the user asks \"is this gap worth pursuing\", \"help me pick a thesis topic\", \"is this idea already taken\", \"find me a defensible research gap\", \"vet this research idea before I commit\", or \"should I do this\". NOT a literature review (use `literature-triage-mat...\n- `gc-minimal-zine-poster-v0-1`: Generate Minimal Zine Poster v0.1 poetic paper-poster prompts and the matching generated image. Use when the user gives a theme, sentence, object, mood, article idea, photo, or content brief and wants a quiet Japanese/Korean zine-like editorial poster with large negative space, aged paper texture, experimental typography, restrained color accents, and a generated bitmap image.\n- `grilling`: Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.\n- `grillme-workflow`: Use when implementing complex multi-step tasks that benefit from structured plan review, multi-model validation, and post-execution verification\n- `humanizer`: Remove signs of AI-generated writing from text. Use when editing or reviewing text to make it sound more natural and human-written. Based on Wikipedia's comprehensive \"Signs of AI writing\" guide. Detects and fixes patterns including: inflated symbolism, promotional language, superficial -ing analyses, vague attributions, em dash overuse, rule of three, AI vocabulary words, passive voice, negative parallelisms, and filler phrases.\n- `improve-animations`: Survey a codebase's animation and motion code as a senior motion advisor, then produce a prioritized audit and self-contained implementation plans for other agents (or cheaper models) to execute.

Use when the user asks to \"orient me in this project\", \"what is this repo about\", or \"build a context map for this paper\" — and the project already has .research/ manifests (or trigger research-context-compressor first).\n- `research-report`: 将deep调研结果汇总为markdown报告，覆盖所有字段，跳过不确定值。\n- `research-session-management`: Use when starting or ending any thesis writing session — manages INDEX files, handoff documents, and startup/shutdown protocols for cross-session continuity. Triggers on 'new thesis session', 'session handoff', 'continue thesis work', 'pick up where left off', 'end session'.\n- `research-style-audit`: Use after completing any thesis section draft — runs programmatic style audit to catch Pattern\n- `research-task-file`: Use when creating self-contained task files for autonomous AI agent execution — goal-oriented instructions with context, decision frameworks, and validation criteria. Triggers on 'create task file', 'autonomous task', 'agent task', 'data extraction task', 'TASK file', 'batch processing task'.\n- `research-three-stage-review`: Use after completing a thesis prose draft — runs three independent review stages with different perspectives and information access. Triggers on 'review draft', 'check section', 'draft review', 'quality check', 'before sending to advisor'.\n- `research-writing`: Use when starting any academic thesis or dissertation writing task — routes to the correct thesis sub-skill based on the current phase of work. Triggers on 'thesis', 'dissertation', 'chapter writing', 'section writing', 'defense prep', 'academic writing with AI'.\n- `research-writing-brief`: Use when planning any thesis section before writing prose — creates a Writing Brief with boundary rules, internalization check, verified data table, and paragraph-level outline with argumentative purposes. Triggers on 'plan section', 'write section X.Y', 'prepare to write', 'writing brief', 'section outline'.\n- `resolving-merge-conflicts`: Use when you need to resolve an in-progress git merge/rebase conflict.\n- `sandbox-sdk`: Build sandboxed applications for secure code execution. Load when building AI code execution, code interpreters, CI/CD systems, interactive dev environments, or executing untrusted code. Covers Sandbox SDK lifecycle, commands, files, code interpreter, and preview URLs. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `scheduled-task-planner`: 分析定时任务需求，确定最优部署方案（Cloudflare Worker 或本地 launchd）\n- `sequential-thinking`: Structured reflective problem-solving methodology. Process: decompose, analyze, hypothesize, verify, revise. Capabilities: complex problem decomposition, adaptive planning, course correction, hypothesis verification, multi-step analysis. Actions: decompose, analyze, plan, revise, verify solutions step-by-step. Keywords: sequential thinking, problem decomposition, multi-step analysis, hypothesis verification, adaptive planning, course correction, reflective thinking, step-by-step, thought sequ...\n- `skill-creator`: Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.\n- `slack-gif-creator`: Knowledge and utilities for creating animated GIFs optimized for Slack. Provides constraints, validation tools, and animation concepts. Use when users request animated GIFs for Slack like \"make me a GIF of X doing Y for Slack.\"\n- `tdd`: Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions \"red-green-refactor\", or wants integration tests.\n- `test`: Test features before users find bugs. Use when feature is built, before deploying, or when bugs reported. Covers manual testing, edge cases, cross-browser testing, and testing checklists for non-technical founders.\n- `theme-factory`: Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.\n- `turnstile-spin`: Set up Cloudflare Turnstile end-to-end in a project — scan the codebase, create the widget via the Cloudflare API, deploy the managed siteverify Worker, write the frontend snippets, validate, and persist the skill. Load this when a user asks to add Turnstile, set up CAPTCHA, protect a form from bots, or fix a Turnstile integration. Mirrors developers.cloudflare.com/turnstile/spin.\n- `web-artifacts-builder`: Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.\n- `web-perf`: Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (LCP, INP, CLS) and supplementary metrics (FCP, TBT, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps.

Load before running wrangler commands to ensure correct syntax and best practices. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `xlsx`: Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in...\n- `zotero-library-curator`: Audit and curate a Zotero library — find duplicate DOIs, orphan items missing required tags, propose collection rebinds, identify bloated or under-used collections, generate tag hygiene reports, emit preview-only cleanup plans. Use when the user asks to \"audit Zotero\", \"find duplicates\", \"tag hygiene report\", \"which collections are bloated or under-used\", or \"propose a Zotero cleanup plan\". Defers all CRUD operations to the standalone `zotero-skills` skill or `research-hub zotero` CLI. Includ...\n\n\nIf the user names a skill, or the task clearly matches a skill's description, call the `skill` tool with the exact skill name before taking task actions. Load all applicable skills, then follow their full instructions.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

-You are an AI agent powered by the DeepSeek Harness SDK.
-
-You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
-
-Verify your work by running the code or tests. Keep answers brief and factual.
-
-
-Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
-
-Use the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.
-
-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.
-
-Check the [exit code: N] marker on every bash result; investigate failures before moving on.
-
-Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
-
-Current DSH file policy: workspace-write. The write and edit tools and one-shot bash commands may modify files under the session workspace: "{{cwd}}". Some platform temporary areas may also be writable.
-
-Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
-
-
-
-Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use search/read for ordinary navigation. Use lsp when textual matches are ambiguous or before a change requires precise definitions, implementations, or references. Positions are one-based line and character (UTF-16) at the cursor; an off-symbol position may return no results. findReferences always includes the declaration.
 
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools, one-shot bash commands, or terminal sessions.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use session_search to find relevant work from prior sessions, or session_event_search to search earlier events in one session. Search results are cursor-free and workspace-scoped. Follow a useful hit with session_trace, session_event_trace, or session_event_read when you need lineage, relationships, or exact data.
 
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).

-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.

 Use the web_fetch tool to retrieve the content of a specific HTTP(S) URL (for example a result from web_search). It returns the page content decoded to text. Cite the URL as a markdown link when you use its content.
 
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).

-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

Keep answers brief and\nfactual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nUse a terminal session only when work needs persistent terminal state or interactive stdin; prefer bash/read/write/edit for bounded one-shot operations. Track every terminal session id and close sessions that no longer matter. An inferred_idle or timeout result does not prove the foreground command exited.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation.

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

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

 **One readiness projection owns both Models and onboarding facts.** `ui-models` keeps a single store that joins `llm.providers({})`, redacted `settings.describe({})`, and batched `credentials.describe({refs})`. The onboarding projection selects the `deepseek-official` configurable-provider entry, resolves its `settingsNs` and `settingsPath`, reads the effective `apiKeyEnv`, and evaluates the matching credential descriptor.

+# Agent Note: Versioned GUI welcome onboarding
+
+Status: implemented
+
+English | [中文](2026-07-30-versioned-gui-welcome-onboarding.zh.md)
+
+## Problem
+
+The GUI's credential onboarding begins with a DeepSeek-specific readiness check, but the internal-test notice applies to every user and must precede provider setup even when a credential is already configured. Treating both as independent overlays permits simultaneous dialogs, while a process-local dismissal cannot distinguish a completed notice from a window closed before acknowledgement or intentionally present revised copy once.
+
+## Decision
+
+**The Settings shell coordinates ordered steps.** `settings.onboarding` remains a root-scoped list, but `ui-settings` projects its entry ids and order into one coordinator and mounts only the first incomplete step. The active registrant receives `complete()` and `openSection(id)`; no later step mounts until ownership transfers. The product welcome registers at order `-100`, while `ui-models` retains only the conditional DeepSeek readiness and credential-routing step at order `0`.
+
+**Ownerless product onboarding belongs to `ui-settings-general`.** `src/onboarding-copy.ts` is the single editable source for the complete Chinese notice, its faithful English counterpart, the Continue labels, and `WELCOME_NOTICE_VERSION`. Runtime locale dictionaries derive their welcome values from that file, and tests import the same owner instead of repeating paragraph text. The notice is browser UI only: it creates no Session event and contributes no model-visible content.
+
+**Acknowledgement is durable per Harness profile.** The Host half registers a `ui-onboarding` section in the user-settings seam, stored under the active `$DSH_HOME/settings.yaml`. The browser shows the notice unless `welcomeNoticeVersion` equals the owner constant exactly. Continue applies one path mutation with the current version and calls `complete()` only after the Host commits it; a failed write leaves the notice open, and closing the page or process writes nothing. Bumping the constant intentionally makes every profile acknowledge the revised copy once.
+
+**Concurrent views converge without stale replacement.** The acknowledgement write omits `expectedRevision` deliberately: every tab writes the same version to one path, so the operation is idempotent and preserves sibling fields instead of rebuilding the section. `settings/document-updated` becomes `host/settings-changed`; an already mounted tab refetches and advances when another tab or an external editor commits the current version. The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.
+
+**The welcome modal has one completion path.** It renders no close icon or secondary action, installs no Escape handler, and assigns no click handler to the mask. Its mask starts below the 80 px top chrome and preserves `position:absolute`, zero left/right/bottom offsets, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Continue is the sole button and receives initial focus.
+
+## Alternatives considered
+
+**Browser local storage** — rejected because acknowledgement would follow one browser profile rather than `$DSH_HOME`; a fresh Harness profile could incorrectly inherit a prior acknowledgement, and external profile edits would have no authoritative update stream.
+
+**A second independent modal in `ui-settings-general`** — rejected because list registrants would still stack whenever welcome and credential readiness were both true. Ordered ownership belongs to the shell that declares and renders the list.
+
+**Persisting on render or window close** — rejected because observation is not acknowledgement and close delivery is unreliable. Only the explicit Continue commit may suppress the next launch.
+
+**A generic public settings-exposure flag** — rejected because one product namespace does not justify widening every settings registrant's public configuration surface. The gateway keeps an explicit closed allowlist.
+
+## Consequences
+
+A fresh profile always sees the welcome notice before provider-specific onboarding; an already configured credential skips only the later DeepSeek step. Reloading after Continue stays past the acknowledged version, changing the owner version presents it again, and closing before Continue leaves the next launch unchanged. Focused store and React tests pin exact-version comparison, write failure, sole-action behavior, no-dismiss paths, coordinator ordering, conditional DeepSeek transfer, and HMR cleanup. The real Chromium scenario boots the shipped Web composition with an isolated harness home, verifies the exact mask geometry and computed styles, reloads before and after acknowledgement, continues into missing-credential setup, confirms an acknowledged-version mismatch returns while the credential is configured, and checks the browser console.

+# Agent Note: 版本化 GUI 欢迎引导
+
+Status: implemented
+
+[English](2026-07-30-versioned-gui-welcome-onboarding.md) | 中文
+
+## 问题
+
+GUI 的凭据引导从 DeepSeek 专用的就绪状态检查开始，但内部测试通知适用于每位用户，即使凭据已经配置，也必须先于提供方设置显示。若把两者作为独立浮层处理，多个对话框可能同时出现；仅存于进程内的关闭标记既无法区分通知已完成确认还是窗口在确认前已关闭，也无法在文案有意修订后重新显示一次通知。
+
+## 决策
+
+**设置外壳协调有序步骤。** `settings.onboarding` 仍是根作用域 list，但 `ui-settings` 会把其中各条目的 id 和顺序投影到一个协调器中，并且只挂载第一个未完成的步骤。当前注册方会收到 `complete()` 和 `openSection(id)`；所有权转移前，不会挂载后续步骤。产品欢迎步骤的顺序为 `-100`，`ui-models` 则只保留顺序为 `0` 的 DeepSeek 条件式就绪状态与凭据跳转步骤。
+
+**不属于单一功能的产品引导由 `ui-settings-general` 持有。** `src/onboarding-copy.ts` 是完整中文通知、忠实英文对侧文案、两种语言的「继续」按钮文案和 `WELCOME_NOTICE_VERSION` 的唯一可编辑来源。运行时 locale 字典从该文件派生欢迎文案，测试也导入同一个所有者，而不重复段落文本。该通知只存在于浏览器 UI：它不会创建会话事件，也不会贡献任何模型可见内容。
+
+**确认状态按 Harness profile 持久化。** 宿主端在 user-settings seam 中注册 `ui-onboarding` 分节，并存入当前 `$DSH_HOME/settings.yaml`。除非 `welcomeNoticeVersion` 与文案所有者文件中的常量精确相等，否则浏览器会显示通知。「继续」会以当前版本执行一次路径变更，并且仅在宿主端提交成功后调用 `complete()`；写入失败时通知保持打开，关闭页面或进程则不会写入任何内容。提升该常量会有意要求每个 profile 对修订后的文案重新确认一次。
+
+**并发视图无需陈旧的整体替换即可收敛。** 确认写入有意省略 `expectedRevision`：每个标签页都向同一路径写入相同版本，因此该操作是幂等的，并会保留同级字段，而不是重建整个分节。`settings/document-updated` 会转为 `host/settings-changed`；另一个标签页或外部编辑器提交当前版本后，已挂载的标签页会重新拉取状态并推进。API 网关在可配置提供方 namespace 之外，通过封闭的允许列表暴露这一个产品 namespace，同时不会把它的变更视为模型目录失效事件。
+
+**欢迎模态窗口只有一条完成路径。** 界面不渲染关闭图标或次要操作，不安装 Escape 处理器，也不为遮罩添加点击处理器。遮罩从顶部 80 px 的界面框架下方开始，并保留 `position:absolute`、left/right/bottom 偏移量为零、`rgba(0, 0, 0, 0.24)` 和 `backdrop-filter: blur(2px)`。「继续」是唯一按钮，并会获得初始焦点。
+
+## 曾考虑的替代方案
+
+**浏览器本地存储**：不予采用，因为确认状态会跟随某个浏览器 profile，而不是 `$DSH_HOME`；全新的 Harness profile 可能错误继承此前的确认状态，外部 profile 编辑也没有权威更新流。
+
+**在 `ui-settings-general` 中再增加一个独立模态窗口**：不予采用，因为欢迎通知和凭据就绪状态同时为真时，list 注册方仍会堆叠。声明并渲染该 list 的外壳应当持有有序所有权。
+
+**在渲染或窗口关闭时持久化**：不予采用，因为看见通知不等于确认，窗口关闭事件也无法可靠送达。只有显式提交「继续」才能阻止通知在下次启动时再次显示。
+
+**通用的公开设置暴露标志**：不予采用，因为一个产品 namespace 不足以证明应当扩大每个 settings 注册方的公开配置面。网关保留显式的封闭允许列表。
+
+## 后果
+
+全新 profile 始终会在提供方专用引导之前看到欢迎通知；凭据已经配置时，只会跳过后续 DeepSeek 步骤。点击「继续」后重新加载不会再次显示已确认版本，更改文案所有者文件中的版本值会让通知重新出现，而确认前关闭窗口不会改变下次启动。针对性的 store 与 React 测试固化了精确版本比较、写入失败、单一操作、不可关闭路径、协调器顺序、按条件移交 DeepSeek 步骤和 HMR（热模块替换）清理行为。真实 Chromium 场景会使用隔离的 harness 家目录启动随产品提供的 Web 组合，验证遮罩的精确几何尺寸和计算样式，在确认前后分别重新加载，继续进入凭据缺失设置流程，确认凭据已配置时确认版本不匹配仍会使通知重新出现，并检查浏览器控制台。

-Models settings plugin: the provider configuration page and official-DeepSeek first-run routing overlay. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
+Models settings plugin: the provider configuration page and official-DeepSeek conditional onboarding step. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
 
 Rows are the *configured* providers (their profile resolves in the owning namespace); a whole-section provider whose key is not configured anywhere (the first-run DeepSeek posture) renders as its open setup card instead of a row, and the add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor is a hand-written card per adapter family: the primary field is a single **API key** input — the page never asks for an environment-variable name; a typed key stores **write-only** through `credentials.set` under the profile's reference, deriving `_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. The collapsed 自定义设置 fold carries the curated extras — `baseURL` for both families (the deepseek placeholder shows the public endpoint), plus `reasoningEffort` (deepseek) or `reasoning` (pi-ai); every other profile field stays owned by `settings.yaml`. A row is deletable only when the user layer alone carries it (removal restores the composition base).
 
-The first-run overlay projects `deepseek-official` readiness from that same joined snapshot. A configured literal `apiKey` secret sidecar or configured credential reference suppresses the prompt, including a read-only launch-environment credential. A mounted adapter with a missing writable reference shows one action that opens Settings on the Models section, whose existing setup card exclusively owns key input and `credentials.set`; the overlay never holds a secret. An absent adapter is skipped because browser navigation cannot mount Cordis plugins, while an unusable settings or credential capability produces a deployment diagnostic with the same route to Models.
+The DeepSeek step projects `deepseek-official` readiness from that same joined snapshot after earlier onboarding steps complete. A configured literal `apiKey` secret sidecar or configured credential reference completes the step without rendering, including a read-only launch-environment credential. A mounted adapter with a missing writable reference shows one action that opens Settings on the Models section, whose existing setup card exclusively owns key input and `credentials.set`; the step never holds a secret. An absent adapter is skipped because browser navigation cannot mount Cordis plugins, while an unusable settings or credential capability produces a deployment diagnostic with the same route to Models.
 
 Every edit lands as `settings.mutate` path ops against the stored section — a set per changed field, an unset per cleared one, and a single unset for a deleted row. The page only ever holds the REDACTED descriptor, so it names the fields it can see rather than rebuilding a section: a stored literal secret it never received is mentioned by no op and survives. Each write carries the `revision` the card opened at, so a concurrent write from another tab or an external `settings.yaml` edit is refused as `settings-conflict` and the card asks the user to reopen instead of replaying its stale snapshot. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.

-模型设置插件：提供方配置页和 DeepSeek 官方首次使用跳转浮层。它把三个协议领域汇聚为一个共享快照：`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）；页面据此渲染提供方行，一次只展开一张编辑卡片。
+模型设置插件：提供方配置页和按条件显示的 DeepSeek 官方首次使用引导步骤。它把三个协议领域汇聚为一个共享快照：`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）；页面据此渲染提供方行，一次只展开一张编辑卡片。
 
 行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；密钥未在任何地方配置的整分节提供方（DeepSeek 的首次运行姿态）会渲染为其展开的设置卡片而非一行，「新增」流程则是一张承载休眠目录提供方选择框的卡片——裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器是每个适配器家族各一张的手写卡片：主字段是单独一个 **API 密钥**输入框——页面从不询问环境变量名；键入的密钥经 `credentials.set` 以**只写**方式存入 profile 的引用之下，profile 没有引用时便派生 `_API_KEY`，pi-ai profile 会把这次派生记录为 `apiKeyEnv`，因此 `settings.yaml` 从不携带密钥值。收起的「自定义设置」折叠区承载精选的额外字段——两个家族都有 `baseURL`（deepseek 的占位符显示公共端点），另加 `reasoningEffort`（deepseek）或 `reasoning`（pi-ai）；其余每个 profile 字段仍归 `settings.yaml` 所有。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。
 
-首次使用浮层从同一个联接快照得出 `deepseek-official` 的就绪状态。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，浮层就不再显示，其中包括来自启动环境且只读的凭据。适配器已挂载、引用可写但尚未配置时，浮层只显示一个操作按钮，用于打开「设置」的 Models 分区；密钥输入和 `credentials.set` 仅由该分区已有的设置卡片负责，浮层绝不持有 secret。适配器缺失时直接跳过，因为浏览器导航无法挂载 Cordis 插件；设置或凭据能力不可用时则显示部署诊断，并提供同一个前往 Models 的入口。
+前序首次使用引导步骤完成后，DeepSeek 步骤会从同一个联接快照得出 `deepseek-official` 的就绪状态。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，该步骤会直接完成而不渲染，其中包括来自启动环境且只读的凭据。适配器已挂载、引用可写但尚未配置时，该步骤只显示一个操作按钮，用于打开「设置」的 Models 分区；密钥输入和 `credentials.set` 仅由该分区已有的设置卡片负责，该步骤绝不持有 secret。适配器缺失时直接跳过，因为浏览器导航无法挂载 Cordis 插件；设置或凭据能力不可用时则显示部署诊断，并提供同一个前往 Models 的入口。
 
 每一次编辑都以 `settings.mutate` 的路径 op 落到已存分节上——每个变更字段一条 set、每个清空字段一条 unset、删除整行则是单独一条 unset。页面自始至终只持有**脱敏后**的 descriptor，因此它点名自己看得见的字段，而不是重建分节：一个它从未收到过的已存字面机密不会被任何 op 提及，也就得以留存。每次写入都携带该卡片打开时的 `revision`，因此来自另一个标签页或对 `settings.yaml` 的外部编辑所产生的并发写入会以 `settings-conflict` 被拒绝，卡片会请用户重新打开，而不是把自己的陈旧快照重放上去。页面加载完成后会在推送的失效事件（`settings/changed`、`credentials/changed`、`models/changed` 与 `connection/reset`）上重拉，因此外部的 `settings.yaml` 编辑、第二个标签页或 settings 新生的路由都无需轮询即可收敛。

Feature-owned rows (Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.
+
+`src/onboarding-copy.ts` is the single editable owner of the complete Chinese and English notice plus `WELCOME_NOTICE_VERSION`. The Host half registers `ui-onboarding` in the user-settings seam; the browser compares `welcomeNoticeVersion` for exact equality and writes the current value only after Continue succeeds. The path mutation is idempotent across tabs and preserves sibling settings, while `host/settings-changed` makes an externally acknowledged notice advance without a reload. A different version deliberately presents the notice again. The welcome UI has no close, Escape, mask-click, or secondary path, and none of its copy or acknowledgement enters a Session log or model request.

+`src/onboarding-copy.ts` 是完整中英文通知文案和 `WELCOME_NOTICE_VERSION` 的唯一可编辑来源。宿主端在 user-settings seam 中注册 `ui-onboarding`；浏览器比较 `welcomeNoticeVersion` 是否精确相等，仅在「继续」操作成功后写入当前值。该路径变更在不同标签页间幂等，并会保留同级设置；`host/settings-changed` 则让页面在通知被外部确认后，无需重新加载即可推进。版本不同时，系统会有意重新显示通知。欢迎界面没有关闭操作、Escape、点击遮罩或次要操作路径，其文案和确认状态均不会进入会话日志或模型请求。

-Settings shell plugin: a pure composition face. It occupies `sidebar.settings` with the trigger chrome and modal settings panel, and declares the slots registrants fill: `settings.trigger` / `settings.header` / `settings.close` (chrome content), `settings.section` (one page per feature), and `settings.onboarding` (feature-owned overlays on the empty Hero).

+Settings shell plugin: a pure composition face. It occupies `sidebar.settings` with the trigger chrome and modal settings panel, and declares the slots registrants fill: `settings.trigger` / `settings.header` / `settings.close` (chrome content), `settings.section` (one page per feature), and `settings.onboarding` (ordered feature-owned steps on the empty Hero). The shell ships no copy and reads no locale state — all text arrives from registrants (ui-settings-general owns chrome, General, and the product welcome step; features own their sections, rows, and conditional onboarding steps).
 
-The shell supplies onboarding registrants only two navigation facts: whether the session surface is the empty Hero and an `openSection(id)` callback that opens the panel on a registered section. Registrants own capability readiness, dismissal, copy, and mutations; the shell therefore does not become a second configuration fact source.
+The shell projects the onboarding ledger into ascending order and mounts exactly one step at a time. The active registrant receives its id, `complete()`, and an `openSection(id)` callback; completing or skipping transfers ownership to the next entry. Registrants own durable completion, capability readiness, copy, and mutations, so two independently registered dialogs cannot stack and the shell does not become a second configuration fact source.

+外壳将首次使用引导记录按升序投影，并且每次只挂载一个步骤。当前注册方会收到该条目的 id、`complete()` 和 `openSection(id)` 回调；完成或跳过当前步骤后，所有权转交给下一项。持久化完成状态、能力就绪状态、文案和变更操作均由注册方持有，因此两个独立注册的对话框无法堆叠，外壳也不会成为第二个配置事实来源。

Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `skill.list` serves the browser's user-selected model-reference path, so it returns only skills that are both model-invocable and user-invocable; this domain has no direct skill-loading RPC. `command.execute` runs a slash-command line host-side with pure admission semantics: the response reports whether the line resolved to a handler plus the minted lifecycle `commandId` when it did (correlating the acknowledgment with the flow node), while the outcome rides the durably logged `command/run`/`command/done` lifecycle pair broadcast on the mux stream; the carrier's request signal cancels the running handler. `host/commands-changed` is the catalog invalidation frame: clients refetch `command.list` instead of diffing.

Any write may carry `expectedRevision`; a stale one answers `settings-conflict` with both revisions rather than overwriting the writer that landed first, and every other seam refusal folds into `settings-rejected`.

 Both positive controls therefore failed the pre-registered sensitivity gate. The formal twelve-session Candidate A and B arms were not run, and these experiments do not select or validate the current wording. They establish that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
 
-The cache-safe delivery rework then supplied a separate, non-statistical acceptance comparison over the neutral Web task `Create the relative path policy-neutral.txt ...`; it does not replace the pre-registered twelve-session experiment. Candidate A's categorical read-only statement produced a text refusal with zero tool calls. Candidate B added one composition-conditioned sentence only for enforced families whose tools expose escalation. A fresh real-provider run then issued an ordinary `write`, observed the read-only denial, retried the same operation in the same turn with `sandbox_permissions: "workspace-write"`, received approval, read the file back, and verified the exact contents. It made no speculative escalation. Across the permission switches and four mutation steps, cache reads were 14,848–15,872 tokens while uncached input was 59–251 tokens per request, directly demonstrating the stable-prefix benefit.

The following skills are available in this session:\n\n\n- `15-05-premortem`: Use before starting risky work — rebases, large refactors, multi-file migrations, or deploys — to identify failure modes and mitigations in advance.\n- `acceptance-criteria`: 检查Acceptance Criteria格式和完整性，验证是否符合Given-When-Then结构、覆盖正常流程/边界条件/异常场景。适合在为User Story编写AC后、准备测试用例前使用，当需要验收AC质量时。帮助不熟悉BDD的PM/BA确保AC明确、可测试、覆盖完整，避免遗漏关键场景。\n- `agents-sdk`: Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `aico-pm-user-story-writing`: Transform requirements into well-structured User Stories using \"As a [user], I want [goal], So that [benefit]\" format with Given/When/Then acceptance criteria. Use this skill when: - User asks to \"write user story\", \"create story\", \"add story\" - User mentions \"user story\", \"backlog item\", \"story\" - Running /pm.plan and need to break PRD into implementable stories - Creating backlog items for development team - Need to formalize a requirement into standard story format - Converting feature req...\n- `algorithmic-art`: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.\n- `animation-vocabulary`: Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term (\"the bouncy thing when a popover opens\" → Pop in; \"the iOS rubber-band scroll\" → Rubber-banding). Use when the user asks \"what's it called when…\", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.\n- `app-comprehensive-test-generator`: Generate exhaustive user-flow and edge-case test scenarios from an app's codebase, produce scenario .md files, execute tests using connected or newly created MCPs, and produce an app.qa.report.md summarizing failures and suggested fixes.\n- `apple-design`: Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.\n- `brainstorming`: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- `brand-guidelines`: Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.\n- `canvas-design`: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.\n- `claude-api`: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answ...\n- `cloudflare`: Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), feature flags (Flagship), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `cloudflare-email-service`: Send and receive transactional emails with Cloudflare Email Service (Email Sending + Email Routing). Use when building email sending (Workers binding or REST API), email routing, Agents SDK email handling, or integrating email into any app — Workers, Node.js, Python, Go, etc. Also use for email deliverability, SPF/DKIM/DMARC, wrangler email setup, MCP email tools, or when a coding agent needs to send emails.

Mirrors developers.cloudflare.com/turnstile/spin.\n- `web-artifacts-builder`: Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.\n- `web-perf`: Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (LCP, INP, CLS) and supplementary metrics (FCP, TBT, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps. Use when asked to audit, profile, debug, or optimize page load performance, Lighthouse scores, or site speed. Biases towards retrieval from current documentation over pre-trained knowledge.\n- `webapp-testing`: Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.\n- `workers-best-practices`: Reviews and authors Cloudflare Workers code against production best practices. Load when writing new Workers, reviewing Worker code, configuring wrangler.jsonc, or checking for common Workers anti-patterns (streaming, floating promises, global state, secrets, bindings, observability). Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `wrangler`: Cloudflare Workers CLI for deploying, developing, and managing Workers, KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Containers, Queues, Workflows, Pipelines, and Secrets Store. Load before running wrangler commands to ensure correct syntax and best practices. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `xlsx`: Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in...\n- `zotero-library-curator`: Audit and curate a Zotero library — find duplicate DOIs, orphan items missing required tags, propose collection rebinds, identify bloated or under-used collections, generate tag hygiene reports, emit preview-only cleanup plans. Use when the user asks to \"audit Zotero\", \"find duplicates\", \"tag hygiene report\", \"which collections are bloated or under-used\", or \"propose a Zotero cleanup plan\". Defers all CRUD operations to the standalone `zotero-skills` skill or `research-hub zotero` CLI. Includ...\n\n\nIf the user names a skill, or the task clearly matches a skill's description, call the `skill` tool with the exact skill name before taking task actions. Load all applicable skills, then follow their full instructions. This catalog contains summaries only; do not infer or follow a skill's instructions until it has been loaded.\n"}],"source":{"kind":"plugin","plugin":"dsh-tool-skill"},"role":"user","id":"99ab4893-10ee-4c69-b9dc-ff46ccba6026"},"surfaceOp":"append"}

Use when the user asks to \"orient me in this project\", \"what is this repo about\", or \"build a context map for this paper\" — and the project already has .research/ manifests (or trigger research-context-compressor first).\n- `research-report`: 将deep调研结果汇总为markdown报告，覆盖所有字段，跳过不确定值。\n- `research-session-management`: Use when starting or ending any thesis writing session — manages INDEX files, handoff documents, and startup/shutdown protocols for cross-session continuity. Triggers on 'new thesis session', 'session handoff', 'continue thesis work', 'pick up where left off', 'end session'.\n- `research-style-audit`: Use after completing any thesis section draft — runs programmatic style audit to catch Pattern\n- `research-task-file`: Use when creating self-contained task files for autonomous AI agent execution — goal-oriented instructions with context, decision frameworks, and validation criteria. Triggers on 'create task file', 'autonomous task', 'agent task', 'data extraction task', 'TASK file', 'batch processing task'.\n- `research-three-stage-review`: Use after completing a thesis prose draft — runs three independent review stages with different perspectives and information access. Triggers on 'review draft', 'check section', 'draft review', 'quality check', 'before sending to advisor'.\n- `research-writing`: Use when starting any academic thesis or dissertation writing task — routes to the correct thesis sub-skill based on the current phase of work. Triggers on 'thesis', 'dissertation', 'chapter writing', 'section writing', 'defense prep', 'academic writing with AI'.\n- `research-writing-brief`: Use when planning any thesis section before writing prose — creates a Writing Brief with boundary rules, internalization check, verified data table, and paragraph-level outline with argumentative purposes. Triggers on 'plan section', 'write section X.Y', 'prepare to write', 'writing brief', 'section outline'.\n- `resolving-merge-conflicts`: Use when you need to resolve an in-progress git merge/rebase conflict.\n- `sandbox-sdk`: Build sandboxed applications for secure code execution. Load when building AI code execution, code interpreters, CI/CD systems, interactive dev environments, or executing untrusted code. Covers Sandbox SDK lifecycle, commands, files, code interpreter, and preview URLs. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `scheduled-task-planner`: 分析定时任务需求，确定最优部署方案（Cloudflare Worker 或本地 launchd）\n- `sequential-thinking`: Structured reflective problem-solving methodology. Process: decompose, analyze, hypothesize, verify, revise. Capabilities: complex problem decomposition, adaptive planning, course correction, hypothesis verification, multi-step analysis. Actions: decompose, analyze, plan, revise, verify solutions step-by-step. Keywords: sequential thinking, problem decomposition, multi-step analysis, hypothesis verification, adaptive planning, course correction, reflective thinking, step-by-step, thought sequ...\n- `skill-creator`: Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.\n- `slack-gif-creator`: Knowledge and utilities for creating animated GIFs optimized for Slack. Provides constraints, validation tools, and animation concepts. Use when users request animated GIFs for Slack like \"make me a GIF of X doing Y for Slack.\"\n- `tdd`: Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions \"red-green-refactor\", or wants integration tests.\n- `test`: Test features before users find bugs. Use when feature is built, before deploying, or when bugs reported. Covers manual testing, edge cases, cross-browser testing, and testing checklists for non-technical founders.\n- `theme-factory`: Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.\n- `turnstile-spin`: Set up Cloudflare Turnstile end-to-end in a project — scan the codebase, create the widget via the Cloudflare API, deploy the managed siteverify Worker, write the frontend snippets, validate, and persist the skill. Load this when a user asks to add Turnstile, set up CAPTCHA, protect a form from bots, or fix a Turnstile integration. Mirrors developers.cloudflare.com/turnstile/spin.\n- `web-artifacts-builder`: Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.\n- `web-perf`: Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (LCP, INP, CLS) and supplementary metrics (FCP, TBT, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps.

Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `wrangler`: Cloudflare Workers CLI for deploying, developing, and managing Workers, KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Containers, Queues, Workflows, Pipelines, and Secrets Store. Load before running wrangler commands to ensure correct syntax and best practices. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `xlsx`: Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in...\n- `zotero-library-curator`: Audit and curate a Zotero library — find duplicate DOIs, orphan items missing required tags, propose collection rebinds, identify bloated or under-used collections, generate tag hygiene reports, emit preview-only cleanup plans. Use when the user asks to \"audit Zotero\", \"find duplicates\", \"tag hygiene report\", \"which collections are bloated or under-used\", or \"propose a Zotero cleanup plan\". Defers all CRUD operations to the standalone `zotero-skills` skill or `research-hub zotero` CLI. Includ...\n\n\nIf the user names a skill, or the task clearly matches a skill's description, call the `skill` tool with the exact skill name before taking task actions. Load all applicable skills, then follow their full instructions.

Subject: [PATCH 100/278] test(tui): cover diffContentLines empty-side arm
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The coverage lane flagged transcript.ts line 63 (diffContentLines' empty-text
return) uncovered: the same-file diff test only fed newline-terminated sides.
Add a third hunk removing a line with an empty added side (a full deletion), so
the empty arm runs and the footer proves the empty side draws no `+ ` row
(+2 -1 · 1 file). Raise the test's line budget so every hunk row stays visible.

Subject: [PATCH 101/278] fix(client-web): pin keyed WebRow in boot smoke, show
 empty-search feedback

- built-boot smoke asserts [data-variant=web][data-tool=web_search/fetch]
  (the keyed WebRow) instead of [data-web] (which WebBlock draws even on the
  GenericToolCard fallback, so a silent keyed-registration failure passed).
- WebBlock renders an explicit empty-state note when a search returns no
  answer and no sources, instead of a blank 
        ; the chat row does not
  surface the raw result content, so the backend's 'No results found.' was
  otherwise invisible.
- README (ui-conversation, ui-primitives) and the frontend Agent Note record
  the unknown-web-kind null arm, the details-panel flattened body, and the
  empty-search copy; pairings re-recorded.

-`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), and for a generic result view (a web tool's error path returns the generic card, whose text the generic path preserves).

 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.

 **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.

 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.

 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 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)).

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.

 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: '', 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).

-`WebBlock` renders a completed web retrieval, one component for both kinds of the `web` render intent (discriminated by `kind`). A `search` shows an optional provider answer (through `MarkdownText`) above an ordered citation list: each source is a safe external link labelled by its title, or its hostname, falling back to the raw URL when the URL does not parse or has no hostname (a `file:`/`data:` URL) so a label is never blank; its snippet and publication date render below it. Only http(s) URLs become anchors (`target`/`rel` set) — the http(s) subset of the allowlist `MarkdownText` applies to untrusted links (it also permits `mailto:`, excluded here); any other URL renders as plain text. A long list caps at `maxSources` (default 16, the TerminalBlock split arithmetic) with a head/tail collapse; the collapsed tail keeps each source's original citation number via `
      1. `, and the expand control is a marker-less `
      2. ` so the `
          ` stays valid HTML. A `fetch` shows a compact summary: the linked final URL and its HTTP status. Both mark a capped retrieval. Rationale: [the web result card note](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card-frontend.md).

Subject: [PATCH 102/278] fix(fs): correct Note pre-release link and restore
 read.ts decline coverage

The Note's pre-release-stance link used the wrong depth and target
(../../../CLAUDE.md); point it at ../../../../AGENTS.md with the section
anchor so verify-md-links passes. The presentResult decline test's meta
lacked the now-required offset, so it declined at meta narrowing instead of
exercising the content-shape decline (read.ts:181-183); add offset back.

 The read tool projects the structured window through `output.presentationMeta`, the same persisted channel write/edit use for their applied-diff hunks ([canonical tool output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). `presentationMeta` runs once for a top-level surface call, returns `{ path, offset, lines, totalLines, lang? }` as JSON the session validates and stores on the result's `meta`, and `presentResult` narrows that meta back into the `ReadResultView` on both live and replay paths. `offset` (the 1-based first line the window requested) rides along because a byte cap below the first selected line yields an empty `lines` array with a positive `totalLines`; without the persisted `offset` a replayed card of such a window could not report where it starts or where a continuation resumes, and the last-line and re-parse fallbacks are both lossy. Without this channel the line array and total would be unreachable: the raw output object is not on the wire, and re-parsing the `N: text` text is lossy and fragile against the truncation footer.
 
-`presentResult` returns `undefined` — the generic fallback — whenever the meta is absent or malformed (`readMetaFromMeta` narrows it defensively, so a replay of an older logged result never throws), whenever the result is an error, and whenever the single text block is not the read envelope. A pre-card logged result — a valid read envelope with no persisted `meta`, recorded before this card existed — takes that same `undefined` path deliberately: the client falls back to the raw `result.content`, so it shows the enveloped `//` text rather than the envelope-stripped generic card the old presenter returned. This is the accepted degradation under the [pre-release stance](../../../CLAUDE.md): reject the old on-disk format rather than add an envelope-stripping compatibility branch, since this PR re-records every published fixture and the session format promises no backward compatibility. On the success path `presentResult` carries `content` (the envelope-stripped text) alongside the structured fields, so a UI without the read capability, including the current TUI, renders the file text through the generic/default card arm exactly as before. The TUI's `renderBody` switch (`packages/ui/tui/src/components/transcript.ts`) is not `assertNever`-exhaustive: `terminal` and `diff` have arms and everything else falls through to the generic arm, which reads `view.content`. That default arm alone was not enough: `render()` sets `genericContent` — and with it the dim-Markdown `dimBody` treatment — on a separate gate that was `card === 'generic'` only, so a `read` card would have kept the text but lost its dim styling. The gate now admits `card: 'read'` too, taking `content` down the same dim-Markdown path, so a read renders in the TUI exactly as it did before the read card existed.

Subject: [PATCH 104/278] docs: generate THIRD_PARTY_NOTICES.md and gate it in
 doc-sync

Replace the hand-written inventory with scripts/gen-third-party-notices.ts,
verified fresh by a doc-sync leaf gate. Tier by declaring workspace area
rather than manifest section, so test-support runtime declarations stay
dev-only and every mountable plugin's dependencies are disclosed as
runtime; list the pnpm-patched packages; point the Python closure at
uv.lock. Re-record the translation-prompt snapshot the README link
invalidated.

+# Agent Note: Generated third-party notices
+
+Status: implemented
+
+English | [中文](2026-07-30-generated-third-party-notices.zh.md)
+
+## Problem
+
+Open-sourcing this repository requires disclosing the third-party software it depends on, with each project's license. The disclosure has to be complete, has to stay true as dependencies change, and has to say something a reader can act on — which of these packages end up on a user's machine, and which only build and test the repository.
+
+A hand-written inventory answers none of those durably. Roughly a hundred rows of names and license strings derived from manifests drift silently the moment a package is added, removed, or relicensed, and nothing in `doc-sync` would notice.
+
+## Decision
+
+[`THIRD_PARTY_NOTICES.md`](../../../../THIRD_PARTY_NOTICES.md) is generated by [`scripts/gen-third-party-notices.ts`](../../../../scripts/gen-third-party-notices.ts) from the workspace manifests, `vendor/README.md`, the `pyproject.toml` files, and `pnpm-workspace.yaml`. `pnpm run verify-third-party-notices` runs the generator with `--check` as a `doc-sync` leaf gate, so a dependency change that skips regeneration fails the same way a stale catalog does. The root README pair links the file from its License section.
+
+The file discloses **direct** dependencies only. The complete npm closure with pinned versions already lives in `pnpm-lock.yaml` (`pnpm licenses list` renders it) and the Python closure in `python/sdk/uv.lock`; re-materializing either as prose would be a second, worse copy.
+
+**Tiering is by declaring area, not by manifest section.** A package is a runtime dependency when any manifest outside `DEV_ONLY_AREAS` — the root manifest, `packages/support/`, `packages/client/test-runtime/`, `website/`, `examples/`, `native/` — names it under `dependencies` or `optionalDependencies`. Section names alone are wrong in both directions: a test-support package declares `vitest` under `dependencies` without shipping it, and the `bin/dsh` launcher execs through `tsx`, which no manifest declares as a runtime dependency at all (the generator marks it runtime explicitly).
+
+The runtime tier deliberately covers **every mountable plugin**, not just what the CLI, Web UI, and Python runtime load by default. `scripts/install.sh` installs the repository itself, so a user's `cordis.yml` can mount any plugin package; `@modelcontextprotocol/sdk` and the OpenTelemetry packages reach real users even though no default assembly imports them. Under-disclosure is the costly direction for a legal notice.
+
+License and repository metadata come from the installed pnpm store, so the generator requires an installed tree and fails loud when a package resolves to neither, rather than emitting an empty cell. `OVERRIDES` carries the packages whose published manifest cannot answer — Rust-built npm bins that omit `license`, and the `modelcontextprotocol/servers` packages whose repository is mid MIT→Apache-2.0 relicensing, so their effective terms are per-contribution. Vendored packages are cross-checked against `vendor/README.md` and rejected if any is not MIT, and `pnpm-workspace.yaml`'s `patchedDependencies` are listed under the runtime table because pnpm applies those patches at install time — shipped artifacts carry modified copies of `@earendil-works/pi-tui` and `node-pty`, and the patch files are the record of what changed.
+
+## Testing
+
+[`scripts/gen-third-party-notices.spec.ts`](../../../../scripts/gen-third-party-notices.spec.ts) pins the tiering rule against fixture manifests — including the two cases that motivate it, a `dependencies` entry of a test-support package and a plugin package no app mounts — and pins that the vendored-table parser reads the committed manifest and yields nothing when the table shape changes, which is what makes the generator fail loud rather than emit an empty section.
+
+## Alternatives considered
+
+**Keep the hand-written file and review it at release time.** Reviewing a hundred derived rows by eye is exactly the work a generator does correctly, and the file's own claim — that it lists every direct dependency — would be unverified between releases.
+
+**Enumerate the full transitive closure.** The closure is thousands of packages, already recorded in the lock files with exact versions, and would bury the direct dependencies that a reader actually evaluates. The file points at the lock files and the `pnpm licenses list` renderer instead.
+
+**Tier by manifest section (`dependencies` vs `devDependencies`).** Mechanically simple and wrong on real data in both directions, as the tiering paragraph above records.
+
+**Tier by reachability from the shipped assemblies only** (`apps/*` plus `python/sdk-runtime`). This produces a tighter runtime tier, but classifies the MCP client and the OpenTelemetry exporter as development-only even though a user running the installed repository can mount them. It understates the disclosure, which is the wrong direction to err for a legal notice.
+
+**Emit the notices as a bilingual pair.** Every other root document is paired, but the file is a table of upstream package names, SPDX identifiers, and URLs; the translatable surface is a handful of section blurbs. `scripts/translation-pairing.ts` scopes discovery to `README*`, `.agents/notes/**`, `docs/**`, and `python/**`, so a root non-README file is outside the bilingual corpus by construction, and the README pair carries the bilingual entry points into it.
+
+## Consequences
+
+Adding or removing a dependency now requires running `pnpm run gen-third-party-notices` and committing the result; `doc-sync` fails otherwise. That is the intended cost — the disclosure cannot silently go stale.
+
+The generator needs an installed tree, which makes it heavier than a pure-source generator, and a new package with unusable published metadata needs an `OVERRIDES` entry rather than silently rendering a blank license. Both failures are loud and name the remedy.
+
+The tiering rule is a policy encoded in one constant. Adding a workspace area that never ships — a second test-infrastructure tier, another site — requires extending `DEV_ONLY_AREAS`, or its dependencies will be disclosed as runtime.

+Status: implemented

+
+## Problem
+
+本仓库开源需要披露所依赖的第三方软件及各自的许可证。这份披露必须完整，必须随依赖变化保持为真，还必须给出读者用得上的信息：哪些包最终会进到用户机器上，哪些只用于构建和测试。
+
+手写清单无法长期满足其中任何一条。约一百行从各清单文件推导出来的包名与许可证标识，只要有依赖新增、移除或换用许可证就会悄悄失真，而 `doc-sync` 不会察觉。
+
+## Decision
+
+[`THIRD_PARTY_NOTICES.md`](../../../../THIRD_PARTY_NOTICES.md) 由 [`scripts/gen-third-party-notices.ts`](../../../../scripts/gen-third-party-notices.ts) 依据各工作区清单、`vendor/README.md`、`pyproject.toml` 与 `pnpm-workspace.yaml` 生成。`pnpm run verify-third-party-notices` 以 `--check` 运行生成器，作为 `doc-sync` 的叶子门禁；依赖变了却没重新生成，会像目录过期一样直接失败。根 README 双语两侧都从「许可证」一节链到该文件。
+
+文件只披露**直接**依赖。完整的 npm 闭包连同锁定版本已记录在 `pnpm-lock.yaml`（`pnpm licenses list` 可渲染），Python 闭包记录在 `python/sdk/uv.lock`；再用散文誊一遍只会得到一份更差的副本。
+
+**分层依据是声明方所在区域，而非清单字段名。** 只要 `DEV_ONLY_AREAS` 之外的任一清单——即根清单、`packages/support/`、`packages/client/test-runtime/`、`website/`、`examples/`、`native/` 之外——在 `dependencies` 或 `optionalDependencies` 里点名某个包，它就是运行时依赖。单看字段名在两个方向上都会出错：测试支撑包把 `vitest` 写在 `dependencies` 里却并不交付它；而 `bin/dsh` 启动器 exec 经过的 `tsx`，根本没有任何清单把它声明为运行时依赖，只能由生成器显式标记。
+
+运行时层刻意覆盖**所有可挂载的插件**，而不止 CLI、Web UI 与 Python 运行时默认加载的那些。`scripts/install.sh` 安装的就是仓库本身，用户的 `cordis.yml` 可以挂载任何插件包；`@modelcontextprotocol/sdk` 与 OpenTelemetry 系列即使没有任何默认装配引入，也会触达真实用户。对法务披露而言，披露不足才是代价更高的那个方向。
+
+许可证与仓库地址取自已安装的 pnpm store，因此生成器要求工作树已安装依赖；某个包两处都解析不到时直接失败，而不是留下空单元格。`OVERRIDES` 收录已发布清单答不上来的包：用 Rust 构建、发布时省略 `license` 字段的 npm 可执行包，以及 `modelcontextprotocol/servers` 系列——该仓库正处在 MIT 向 Apache-2.0 的重新许可过程中，实际条款按贡献逐条而定。被源码收编的包会与 `vendor/README.md` 交叉核对，出现非 MIT 即报错；`pnpm-workspace.yaml` 的 `patchedDependencies` 列在运行时表格之后，因为 pnpm 在安装期就会打上这些补丁——交付产物携带的是改动过的 `@earendil-works/pi-tui` 与 `node-pty`，补丁文件本身就是改动的完整记录。
+
+## Testing
+
+[`scripts/gen-third-party-notices.spec.ts`](../../../../scripts/gen-third-party-notices.spec.ts) 用夹具清单钉住分层规则，覆盖促成该规则的两个场景：测试支撑包的 `dependencies` 条目，以及没有任何应用挂载的插件包。它同时钉住被收编包的表格解析器能读出已提交的清单表，且表格形态一变就解析为空——正是这一点让生成器直接失败，而不是产出一个空章节。
+
+## Alternatives considered
+
+**保留手写文件，发版时人工过一遍。** 用肉眼审阅上百行推导数据，恰恰是生成器能做对的活；而且在两次发版之间，文件自称「列出全部直接依赖」这句话无人验证。
+
+**列出完整传递闭包。** 闭包有数千个包，锁文件里已带精确版本，铺开只会淹没读者真正要评估的直接依赖。文件转而指向锁文件与 `pnpm licenses list`。
+
+**按清单字段分层（`dependencies` 与 `devDependencies`）。** 机械上最省事，但在真实数据上两个方向都会出错，理由见上文分层段落。
+
+**只按已交付装配的可达性分层**（`apps/*` 加 `python/sdk-runtime`）。这样得到的运行时层更紧凑，但会把 MCP 客户端与 OpenTelemetry 导出器判为仅开发用途——而运行已安装仓库的用户完全可以挂载它们。这会低估披露，对法务通告来说错在了更危险的一侧。
+
+**把披露文件做成双语对。** 其他根文档都是成对的，但这份文件是上游包名、SPDX 标识与网址构成的表格，可翻译的只有寥寥几段章节导语。`scripts/translation-pairing.ts` 的发现范围限定在 `README*`、`.agents/notes/**`、`docs/**` 与 `python/**`，根目录下的非 README 文件在构造上就不属于双语语料；双语入口由 README 对承担。
+
+## Consequences
+
+此后增删依赖都需要运行 `pnpm run gen-third-party-notices` 并提交结果，否则 `doc-sync` 失败。这正是预期成本——披露不可能再悄悄过期。
+
+生成器需要已安装的工作树，因此比纯源码生成器更重；发布元数据不可用的新包需要补一条 `OVERRIDES`，而不是默默渲染出空白许可证。这两类失败都会明确报错并指出补救方式。
+
+分层规则是编码在一个常量里的政策。若新增了不参与交付的工作区区域——第二层测试基础设施、另一个站点——就要同步扩展 `DEV_ONLY_AREAS`，否则其依赖会被当作运行时依赖披露出去。

The stable symlink `~/.dsh/source/current` points at the active staging worktree, and `dsh` in `~/.local/bin` links to `current/bin/dsh`, so an upgrade repoints one symlink and the `dsh` on PATH never moves. Re-running the command adds a fresh staging worktree from an updated master and repoints `current` at it. See [`scripts/install.sh`](scripts/install.sh) for alternate install locations and other options.\n\n## Use DeepSeek Harness\n\n### Web UI\n\nFor the recommended local interface, build the frontend after installation and after each update, then start the Web UI. Resolve the running checkout from the `dsh` launcher so the command holds regardless of which staging worktree is current (the launcher resolves through the stable `current` symlink):\n\n```sh\ndsh_bin=$(cd \"$(dirname \"$(command -v dsh)\")\" && pwd -P)/$(basename \"$(command -v dsh)\")\nwhile [ -L \"$dsh_bin\" ]; do\n  link=$(readlink \"$dsh_bin\")\n  case $link in /*) dsh_bin=$link ;; *) dsh_bin=$(cd \"$(dirname \"$dsh_bin\")\" && cd \"$(dirname \"$link\")\" && pwd -P)/$(basename \"$link\") ;; esac\ndone\ndsh_dir=$(cd \"$(dirname \"$dsh_bin\")/..\" && pwd -P)\npnpm --dir \"$dsh_dir\" run build && pnpm --dir \"$dsh_dir\" run build:web\ndsh web\n```\n\nThe Web UI is served at `http://127.0.0.1:3080` by default.\n\n### TUI\n\nStart the full-screen terminal interface:\n\n```sh\ndsh\n```\n\n### Headless\n\nRun one task, print the final answer, and exit:\n\n```sh\ndsh -p \"summarize this workspace\"\n```\n\n## Why DeepSeek Harness\n\nBuilt-in capabilities cover file reading, editing, and search; shell execution; reusable skills; task tracking; subagents and workflows; persistent sessions; and context compaction. The TUI also includes Plan Mode.\n\n- **Everything is a plugin.** Models, tools, policies, storage, context management, and interfaces are composable [Cordis plugins](docs/user/develop/basic/index.md), so deployments can extend or replace behavior without forking the agent loop. See the [architecture](docs/architecture.md) for the underlying design.\n- **Code Mode (opt-in).** It exposes a `run_code` tool and a generated TypeScript SDK; only program output re-enters model context. See [Code Mode](packages/core/tools/README.md#code-mode).\n- **Self-referential Cordis tools are opt-in.** They let the agent inspect its live runtime and mount or unmount plugins while it runs. See the [Cordis tools](packages/cordis/tool-cordis/README.md).\n\n## Community\n\nFollow DeepSeek Harness on Twitter for project updates.\n\n## Development\n\n```sh\npnpm install\npnpm run test:coverage\n```\n\nStart with the [development guide](docs/development.md) and read the [architecture](docs/architecture.md) before changing packages.\n\nFor agents, follow [AGENTS.md](AGENTS.md).\n\nDeepSeek Harness is currently pre-release.\n\n## License\n\n[BSD 3-Clause](LICENSE)\n"

See [`scripts/install.sh`](scripts/install.sh) for alternate install locations and other options.\n\n## Use DeepSeek Harness\n\n### Web UI\n\nFor the recommended local interface, build the frontend after installation and after each update, then start the Web UI. Resolve the running checkout from the `dsh` launcher so the command holds regardless of which staging worktree is current (the launcher resolves through the stable `current` symlink):\n\n```sh\ndsh_bin=$(cd \"$(dirname \"$(command -v dsh)\")\" && pwd -P)/$(basename \"$(command -v dsh)\")\nwhile [ -L \"$dsh_bin\" ]; do\n  link=$(readlink \"$dsh_bin\")\n  case $link in /*) dsh_bin=$link ;; *) dsh_bin=$(cd \"$(dirname \"$dsh_bin\")\" && cd \"$(dirname \"$link\")\" && pwd -P)/$(basename \"$link\") ;; esac\ndone\ndsh_dir=$(cd \"$(dirname \"$dsh_bin\")/..\" && pwd -P)\npnpm --dir \"$dsh_dir\" run build && pnpm --dir \"$dsh_dir\" run build:web\ndsh web\n```\n\nThe Web UI is served at `http://127.0.0.1:3080` by default.\n\n### TUI\n\nStart the full-screen terminal interface:\n\n```sh\ndsh\n```\n\n### Headless\n\nRun one task, print the final answer, and exit:\n\n```sh\ndsh -p \"summarize this workspace\"\n```\n\n## Why DeepSeek Harness\n\nBuilt-in capabilities cover file reading, editing, and search; shell execution; reusable skills; task tracking; subagents and workflows; persistent sessions; and context compaction. The TUI also includes Plan Mode.\n\n- **Everything is a plugin.** Models, tools, policies, storage, context management, and interfaces are composable [Cordis plugins](docs/user/develop/basic/index.md), so deployments can extend or replace behavior without forking the agent loop. See the [architecture](docs/architecture.md) for the underlying design.\n- **Code Mode (opt-in).** It exposes a `run_code` tool and a generated TypeScript SDK; only program output re-enters model context. See [Code Mode](packages/core/tools/README.md#code-mode).\n- **Self-referential Cordis tools are opt-in.** They let the agent inspect its live runtime and mount or unmount plugins while it runs. See the [Cordis tools](packages/cordis/tool-cordis/README.md).\n\n## Community\n\nFollow DeepSeek Harness on Twitter for project updates.\n\n## Development\n\n```sh\npnpm install\npnpm run test:coverage\n```\n\nStart with the [development guide](docs/development.md) and read the [architecture](docs/architecture.md) before changing packages.\n\nFor agents, follow [AGENTS.md](AGENTS.md).\n\nDeepSeek Harness is currently pre-release.\n\n## License\n\n[BSD 3-Clause](LICENSE)\n\nThird-party dependencies and their licenses are disclosed in [THIRD_PARTY_NOTICES.md](THIRD_PARTY_NOTICES.md).\n"

Subject: [PATCH 105/278] test: cover the TUI search-card fallback and refresh
 the cordis-inspect golden

- Add a search result-view scenario to the TUI tool-card test so the
  card:'search' fallback branch (no view content -> raw result content) is
  covered; restores transcript.ts branch coverage to 100%.
- Refresh the cordis-inspect-jsdoc golden for the kind -> shape rename in the
  ToolResultView JSDoc that cordis_inspect echoes.

Subject: [PATCH 106/278] test(web): refresh code-mode-round golden for read
 error state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The nested read of a missing file surfaces its error state as 失败 in the
code-dispatch row summary, a consequence of this PR's read-card error
presentation. The golden predated it (never re-recorded while the PR was
conflicting); refreshed keyless via DSH_SNAPSHOT=refresh over the existing
session.jsonl.

Subject: [PATCH 107/278] fix(web-search-card): surface truncation recovery,
 widen cardless fallback, validate wire shape, fix tail-cap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Address the ds-review-bot findings on the search card:

- searchCardModel dropped the result view's `content`, so a capped search's
  `Full … stored at: ` recovery footer vanished from the UI (the card
  replaces the raw text). Thread it through as `SearchCardModel.recovery` and
  render it below the card at all three sites, only when truncated.
- SearchRow's fallback body was gated on `state === 'error'`, so a settled
  non-error call with no card (a successful nested run_code sub-dispatch, a
  legacy generic result) showed only its summary with content lost. Widen it to
  any settled call with `search === null`.
- searchCardModel trusted the `files`/`paths` shape the host wire schema only
  string-checks; a malformed known-kind frame would crash SearchBlock. Validate
  the full shape and fall to the generic path on mismatch.
- SearchBlock's restored tail file header added a row without consuming a tail
  slot, exceeding maxLines by one and overstating the hidden count. Make it
  consume a slot so the visible count holds at maxLines and `hidden` stays exact.

Correct the fixture JSDoc (now genuinely exceeds the row cap) and the Agent Note
recovery-text claim, sync the ui-conversation bilingual README with the search
row, and add an assembled keyless snapshot (apps/web/tests/search-card.snapshot.ts)
that pins the grep card's shape from the built bundles.

-`SearchBlock` is a `ui-primitives` component that renders a completed search as either shape, and the Web render sites for a `grep`/`glob` call consume the search render intent through it. `ui-conversation/src/client/contract/search-card-model.ts` is the single place that turns the snapshot's `resultView` into the component's props, so no render site re-derives the shape. It returns null — the generic path — whenever the result view is not a search card, including a still-running call (a search card is result-time only, so there is nothing before `execute`), a generic result a `grep`/`glob` failure or a nested `run_code` dispatch produces, a terminal result view, and a `card` value this client version does not know.

 The asymmetry with the terminal card is deliberate and inherited from the backend contract: `terminalCardModel` reads both `callView` and `resultView` because a command, cwd, and description exist at call time; `searchCardModel` reads only `resultView` because a search's matches or paths exist only after execution. A running search row therefore shows its summary alone, with no card.

Collapsing a group drops its match rows from the flattened list and from the height cap's arithmetic, but never from the copy text.
 - **Flat path list.** The paths shape renders one path per row, no headers.
-- **A capped indicator.** When `truncated`, the banner summary folds the pre-cap total in — `显示 X / 共 N 处匹配 · K 个文件` for grep, `显示 X / 共 N 个路径` for glob — so the card never presents a capped page as the complete result; a reader who wants the rest follows the spill locator in the model-facing text, exactly as the model does. When not `truncated` the summary is a plain structural count (`{n} 处匹配 · {m} 个文件`, or `{n} 个路径`).

+- **A recovery footer for a capped result.** The card holds only the retained page, but the locator to the rest — grep/glob's `Full … stored at: ` footer — lives only in the result view's `content` text, not in the structured matches/paths. Because every render site replaces the raw result with the card, `searchCardModel` surfaces that flattened `content` as `SearchCardModel.recovery` when (and only when) the result was capped, and each render site draws it below the card. Without this the one path to the dropped rows would vanish from the UI; an uncapped result carries every row, so its `content` adds nothing and is dropped.
 - **No soft wrapping.** Result rows are `white-space: pre` inside a horizontally scrolling box, so a long match line or a deep path scrolls sideways rather than folding.
 - **Height cap with an expand control.** More than `DEFAULT_SEARCH_MAX_LINES` (16) rows shows a head/tail slice with a button reporting the hidden count, the same shape and arithmetic as `TerminalBlock`.
 - **Copy.** The copy control writes the whole structured result — every file and match, or every path — regardless of the height cap or which groups are collapsed, so the clipboard carries the result rather than what the card happens to be showing.

 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)).
 
+A `grep`/`glob` call declaring the `search` render intent renders its result inline, at the same render sites, through ui-primitives' `SearchBlock` — grep's matches grouped by file (each a collapsible header of `lineNumber: line` rows), glob's flat path list. `contract/search-card-model.ts` is the single derivation from the snapshot's `resultView`; unlike the terminal card it reads no `callView`, since a search has no matches or paths before `execute`, so a running search shows its summary alone. It yields null — the generic path — for any non-search result view, a `card` or `kind` this client version does not compile, and (because those ride the untrusted wire frame) a known kind whose `files`/`paths` is malformed. The keyed `SearchRow`, registered under both `grep` and `glob` since the derived `kind` decides the shape, carries the card resident below its summary; the render-site fallback keeps it behind the expand control. Both cap at `CHAT_SEARCH_MAX_LINES` (8) against the panel's 16. A capped search drops rows from the card, but the locator to the rest — grep/glob's `Full … stored at …` footer — lives only in the result text, so the derivation surfaces that as a recovery footer below the card when (and only when) the result was truncated; a settled call with no card at all (an errored search, a nested `run_code` sub-dispatch, a legacy generic result) falls back to its flattened result text so nothing is lost behind a bare summary ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)).
+
 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: '', 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).
 
 The todo surfaces are two registrations over that shape, both plain registrant plugins with `inject: ['slots', 'conversation']`. `TodoRow` takes the `'conversation.chat.toolview'` key `todo_write` and summarizes what the call attempted (`/ 已完成 · ` parsed from its args, falling back to the generic summary on malformed or wrongly-shaped model JSON, and keeping the generic dot for non-ok execution states so a cancelled call never reads as a completed update). `TodoDock` takes the `'conversation.input.dock'` list slot at `order: 10` — between Goal and Queue — and is the plan strip: it reads the host-computed `todos` projection via `useProjection` (standing plan: latest `todo/write` with no later `turn/start`) and renders `TodoPanel`, which takes the plain list, hides itself while the list is empty, and starts collapsed as a header of title plus `"/ tasks ·  in progress"` (status glyphs are the figma check / progress / dashed-pending set). The dock adapter owns the selection so the panel stays a pure function of its props; the standing list lives here rather than in the row so the row stays one line. Anything the input-zone composer chain hides (a `conversation.composer` takeover such as ui-question's) hides the whole dock, this strip included.

 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)）。
 
+声明 `search` 渲染意图的 `grep`／`glob` 调用，会在同样的渲染点上通过 ui-primitives 的 `SearchBlock` 内联渲染其结果——grep 的匹配按文件分组（每个是一个可折叠的头，下辖 `lineNumber: line` 行），glob 是扁平路径列表。`contract/search-card-model.ts` 是从快照的 `resultView` 推导的唯一位置；与终端卡片不同，它不读 `callView`，因为搜索在 `execute` 前没有匹配或路径，所以运行中的搜索只显示摘要。对任何非搜索的结果视图、当前客户端版本无法编译的 `card` 或 `kind`、以及（因为这些都与不可信的 wire 帧同行）一个 `files`／`paths` 格式错误的已知 kind，它都返回 null，落回通用路径。键控的 `SearchRow` 因推导出的 `kind` 决定形态而同时注册在 `grep` 与 `glob` 下，把卡片常驻在摘要行下方；渲染点兜底行则把它保持在展开控件之后。两者上限都是 `CHAT_SEARCH_MAX_LINES`（8），面板为 16。被截断的搜索会从卡片里丢掉一些行，但通往其余部分的定位符——grep/glob 的 `Full … stored at …` 脚注——只存在于结果文本里，因此推导在（且仅在）结果被截断时把它作为恢复脚注画在卡片下方；一个完全没有卡片的已结算调用（出错的搜索、嵌套 `run_code` 子派发、旧日志的 generic 结果）则回退到其压平后的结果文本，从而不让任何内容丢失在一个光秃秃的摘要之后（[决策](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)）。
+
 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: '', 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）。
 
 审批经由本包声明的链接管编辑器：`ApprovalPanel` 注册为按选择器路由的 `'conversation.composer'` 配置项（ui-question 模式），在审批等待未决期间取代 InputBar 占据编辑器（琥珀色条、理由标题、来自运行中调用参数的配对命令行、一次性的拒绝／允许）。`contract/slots.ts` 中的 `PendingApproval` 领域面在运行时 `PendingWait` 载体之上拥有 wire 编码——带审计关联的 `ApprovalResponsePayload` 值；广播的 `approval/resolved` 帧使等待落定并恢复编辑器。侧边栏通过 manager 跟踪的 `waitingApproval` 列表位（未实例化会话同样点亮）镜像该阻塞状态，其优先级高于运行中圆环，直至问题解决。未决等待完全离开消息流：问题（ui-question）与审批（ApprovalPanel）都经编辑器接管作答，不再保留只读占位卡。编辑器底行的 Access 席位挂载 `PermissionSelect`，由 host 计算的 `permissions` 投影经标准工具包 `useProjection` 供数（key 缺席即隐藏 chip）；chip 打开 Menu 原语下拉，kebab-case 预设名渲染为 Title Case 标签（与 `/permission` popup 的显示变换孪生），选中会经由输入栏注入的 `command` 回调提交 `/permission ` 命令行。

Subject: [PATCH 108/278] fix(web-read-card): carry the base's required read
 offset in fixtures and specs

The base's ReadResultView now requires `offset` (persisted so an empty window
still knows its start). The connection fixture's read sample and read-card.spec's
resultRead helper supply it (the window's first line, 41).

 Plan-mode status chip, a pure browser surface plugin. The browser half occupies the conversation-declared `conversation.input.plan` single seat (to the right of the access-mode control); the node half is an empty apply (the roster row). Plan behavior itself — the `/plan` command, the boundary-or-idle-committed `plan/mode` state, the `plan` projection unit, and the policy section — is owned by [`@deepseek-ai/dsh-plan-mode`](../../plan/plan-mode/README.md), composed independently on the host roster.
 
-Plan mode is entered through the `/plan` command only; there is no UI control that turns it on. While the host-computed `plan` projection's effective target is plan mode (`pending ? !active : active` — a folded host value, not client optimism, so an arriving frame corrects the chip either way), the seat renders a read-only "Plan" chip whose hover × executes `/plan off` through `command.execute`; otherwise the seat stays empty — a host without plan-mode (or a Draft with no session) shows nothing. While plan mode is the effective target, the composer textarea's placeholder switches to the plan-task hint — "describe your task to generate plan", localized through ui-conversation's `command.hint` locale namespace and shared verbatim with the claimed `/plan` command hint (rendered by the composer from the same projection; owner-supplied placeholders win).
+Plan mode is entered through the `/plan` command path: users can choose Plan from the composer's `+` Command menu or type `/plan`, while this package renders no inactive plan control. While the host-computed `plan` projection's effective target is plan mode (`pending ? !active : active` — a folded host value, not client optimism, so an arriving frame corrects the chip either way), the seat renders the warn-colored "Plan ×" status button, which executes `/plan off` through `command.execute`; otherwise the seat stays empty — a host without plan-mode (or a Draft with no session) shows nothing.

 The chip carries the accessible description "Plan mode on, press to turn off". Admission failures (`matched: false`, business errors, transport faults) surface as an inline error and the chip stays until the projection confirms the exit.

Subject: [PATCH 110/278] fix(web-search-card): follow base rename kind->shape
 and view-drops-content
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The base (feat/search-presenter) renamed the search result view's discriminant
from `kind` to `shape` and removed the view's `content` field (a UI without a
card now falls back to the raw tool/result content). Adapt the web consumer:

- searchCardModel switches on `result.shape`; SearchBlock's own `kind` prop is
  mapped from it.
- The truncation recovery footer reads the block's raw `content` (where the
  `Full … stored at …` locator now lives) instead of the removed view content.
- Fixture grep/glob views use `shape` and drop `content`; the recovery footer
  rides the raw tool/result text.
- Tests and the bilingual Agent Note follow the rename and the recovery source.

 ## Problem
 
-The `grep` and `glob` tools declare a result-time `card: 'search'` render intent ([search render card](2026-07-30-search-render-card.md)): a `SearchMatchesResultView` (`kind: 'matches'`) carrying grep's matches grouped by file, or a `SearchPathsResultView` (`kind: 'paths'`) carrying glob's flat path list, both with a `truncated`/`total` capping signal. That view already reaches the browser — host, connection, and runtime deliver it onto `ConversationSnapshot` as `resultView` — but the Web client ignored it: every non-terminal, non-diff tool result fell through to the generic card, which renders the model-facing text. A web frontend that wants an expandable per-file group of matches, or a scannable path list, had only the pre-formatted text.

 This is the follow-up the search render card note names: that PR was the backend contract and its two producers; this PR is the web consumer.
 
 ## Decision
 
-`SearchBlock` is a `ui-primitives` component that renders a completed search as either shape, and the Web render sites for a `grep`/`glob` call consume the search render intent through it. `ui-conversation/src/client/contract/search-card-model.ts` is the single place that turns the snapshot's `resultView` into the component's props, so no render site re-derives the shape. It returns null — the generic path — whenever the result view is not a search card, including a still-running call (a search card is result-time only, so there is nothing before `execute`), a generic result a `grep`/`glob` failure or a nested `run_code` dispatch produces, a terminal result view, a `card` value this client version does not know, a `card: 'search'` view whose `kind` this version does not compile, and — because `kind` and the grouped/flat shape ride the same untrusted wire frame the host schema only string-checks — a known `kind` whose `files`/`paths` is missing or malformed (which would otherwise crash `SearchBlock` at `.reduce`/`.map`).

The result-view discriminant is `shape` (not `kind`, which the backend reserves for the call view's icon-picking tag); `SearchBlock`'s own prop stays `kind`, mapped from `shape` in this derivation.
 
 The asymmetry with the terminal card is deliberate and inherited from the backend contract: `terminalCardModel` reads both `callView` and `resultView` because a command, cwd, and description exist at call time; `searchCardModel` reads only `resultView` because a search's matches or paths exist only after execution. A running search row therefore shows its summary alone, with no card.
 
@@ -23,7 +23,7 @@ The component's contract:
 - **Grouped matches, collapsible per file.** Each file is a header row (a bold path plus its match count, the whole row the collapse control) followed by its `lineNumber: line` rows. Collapsing a group drops its match rows from the flattened list and from the height cap's arithmetic, but never from the copy text.
 - **Flat path list.** The paths shape renders one path per row, no headers.
 - **A capped indicator.** When `truncated`, the banner summary folds the pre-cap total in — `显示 X / 共 N 处匹配 · K 个文件` for grep, `显示 X / 共 N 个路径` for glob — so the card never presents a capped page as the complete result. When not `truncated` the summary is a plain structural count (`{n} 处匹配 · {m} 个文件`, or `{n} 个路径`).
-- **A recovery footer for a capped result.** The card holds only the retained page, but the locator to the rest — grep/glob's `Full … stored at: ` footer — lives only in the result view's `content` text, not in the structured matches/paths. Because every render site replaces the raw result with the card, `searchCardModel` surfaces that flattened `content` as `SearchCardModel.recovery` when (and only when) the result was capped, and each render site draws it below the card. Without this the one path to the dropped rows would vanish from the UI; an uncapped result carries every row, so its `content` adds nothing and is dropped.

 - **No soft wrapping.** Result rows are `white-space: pre` inside a horizontally scrolling box, so a long match line or a deep path scrolls sideways rather than folding.
 - **Height cap with an expand control.** More than `DEFAULT_SEARCH_MAX_LINES` (16) rows shows a head/tail slice with a button reporting the hidden count, the same shape and arithmetic as `TerminalBlock`.
 - **Copy.** The copy control writes the whole structured result — every file and match, or every path — regardless of the height cap or which groups are collapsed, so the clipboard carries the result rather than what the card happens to be showing.

 ## Decision
 
-`SearchBlock` 是一个 `ui-primitives` 组件，把一次已完成的搜索渲染成两种形态之一，`grep`/`glob` 调用的 Web 渲染点都通过它消费搜索 render intent。`ui-conversation/src/client/contract/search-card-model.ts` 是把 snapshot 的 `resultView` 转成组件 props 的唯一位置，因此没有渲染点重新推导形态。当结果视图不是搜索卡片时它返回 null（走 generic 路径），包括仍在运行的调用（搜索卡片仅在结果阶段存在，`execute` 前无内容）、`grep`/`glob` 失败或嵌套 `run_code` dispatch 产生的 generic 结果、terminal 结果视图、本客户端版本不认识的 `card` 值、`kind` 是本版本无法编译的 `card: 'search'` 视图，以及 —— 因为 `kind` 和分组/扁平形态与 host schema 只做字符串校验的那同一个不可信 wire 帧同行 —— 一个 `kind` 已知但 `files`/`paths` 缺失或格式错误的视图（否则会让 `SearchBlock` 在 `.reduce`/`.map` 处崩溃）。

 与终端卡片的不对称是刻意的，继承自后端契约：`terminalCardModel` 同时读 `callView` 和 `resultView`，因为命令、cwd、description 在调用时就存在；`searchCardModel` 只读 `resultView`，因为搜索的匹配或路径只在执行后存在。因此运行中的搜索行只显示摘要，没有卡片。

Subject: [PATCH 111/278] docs: keep notices fresh at commit time instead of a
 new CI gate

Regenerate THIRD_PARTY_NOTICES.md from a pre-commit job whenever a
manifest, lock file, vendor manifest, or pyproject is staged, and assert
the committed bytes inside the generator spec the test lane already runs.
Drops the separate doc-sync gate: no extra CI process, and a dependency
edit no longer bounces back from CI to rerun a generator.

 Open-sourcing this repository requires disclosing the third-party software it depends on, with each project's license. The disclosure has to be complete, has to stay true as dependencies change, and has to say something a reader can act on — which of these packages end up on a user's machine, and which only build and test the repository.
 
-A hand-written inventory answers none of those durably. Roughly a hundred rows of names and license strings derived from manifests drift silently the moment a package is added, removed, or relicensed, and nothing in `doc-sync` would notice.

+**Freshness is maintained, not merely enforced.** A pre-commit job regenerates the file and stages it whenever a manifest, lock file, `vendor/README.md`, or `pyproject.toml` is staged, so an unrelated dependency edit never has to come back and rerun a generator. The committed bytes are then asserted inside [`scripts/gen-third-party-notices.spec.ts`](../../../../scripts/gen-third-party-notices.spec.ts), which the test lane already runs — the check adds no gate process, no scheduler slot, and no separate CI step. `pnpm run verify-third-party-notices` remains available for a standalone check.
 
 The file discloses **direct** dependencies only. The complete npm closure with pinned versions already lives in `pnpm-lock.yaml` (`pnpm licenses list` renders it) and the Python closure in `python/sdk/uv.lock`; re-materializing either as prose would be a second, worse copy.

+The same spec that asserts freshness pins the tiering rule against fixture manifests — including the two cases that motivate it, a `dependencies` entry of a test-support package and a plugin package no app mounts — and pins that the vendored-table parser reads the committed manifest and yields nothing when the table shape changes, which is what makes the generator fail loud rather than emit an empty section.
 
 ## Alternatives considered
 
 **Keep the hand-written file and review it at release time.** Reviewing a hundred derived rows by eye is exactly the work a generator does correctly, and the file's own claim — that it lists every direct dependency — would be unverified between releases.
 
+**Verify through a dedicated `doc-sync` gate.** That is how every other generated artifact here is checked, and it was the first shape of this change. It costs a gate process and a scheduler slot in a matrix that is already long, and — worse — its only failure mode is telling a contributor, minutes after they pushed an unrelated dependency bump, to go rerun a generator. Regenerating at commit time removes the interruption, and the assertion inside a spec the test lane already runs keeps the guarantee at no additional CI cost.

 ## Consequences
 
-Adding or removing a dependency now requires running `pnpm run gen-third-party-notices` and committing the result; `doc-sync` fails otherwise. That is the intended cost — the disclosure cannot silently go stale.
+A dependency edit now carries a regenerated notices file into the same commit. Contributors pay one generator run — about a second — on commits that touch a manifest, and nothing on any other commit. Committing with hooks disabled defers the cost to a test-lane failure that names the command.
 
 The generator needs an installed tree, which makes it heavier than a pure-source generator, and a new package with unusable published metadata needs an `OVERRIDES` entry rather than silently rendering a blank license. Both failures are loud and name the remedy.

 **Concurrent views converge without stale replacement.** The acknowledgement write omits `expectedRevision` deliberately: every tab writes the same version to one path, so the operation is idempotent and preserves sibling fields instead of rebuilding the section. `settings/document-updated` becomes `host/settings-changed`; an already mounted tab refetches and advances when another tab or an external editor commits the current version. The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.

Subject: [PATCH 114/278] refactor(ui-primitives): extract shared head/tail cap
 and copy-feedback helpers

The tail-header cap fix pushed SearchBlock's head/tail slicing arithmetic and
its copy-feedback hook over the duplication gate's threshold against the
byte-identical logic in TerminalBlock. Extract both into head-tail-cap.ts
(headTailCap) and use-copy-feedback.ts (useCopyFeedback) and consume them from
both blocks, deleting the clone rather than nudging it under the limit.

web.cordis.yml references @deepseek-ai/dsh-host-directory-picker-auto but

back to built lib/ and verify-cordis-config failed. Add the mapping alongside

Subject: [PATCH 126/278] docs: fix notices template claim and close generator
 omission paths

The template still described the removed doc-sync gate; it now states the
pre-commit + test-lane mechanism that actually runs. Read the nested
native/landlock-run/packages manifests, accept PEP 508 requirements with
no version or with a marker, and reject a vendor/README.md table that
stops covering a vendored directory instead of dropping it silently.
Extend the pre-commit glob to the generator and the build-time pin
source; record the deletion trigger gap the test lane backstops.

+**Freshness is maintained, not merely enforced.** A pre-commit job regenerates the file and stages it whenever a generator input is staged — any manifest, either lock file, `vendor/README.md`, a `pyproject.toml`, the generator itself, or the script holding the build-time pin — so an unrelated dependency edit never has to come back and rerun a generator.

+One trigger gap is accepted rather than worked around: lefthook inspects only files present on disk, so **deleting** a manifest runs no job, and removing a package reaches the assertion in the test lane instead. Reconstructing the staged file list to include deletions was tried and does not work — lefthook filters the list against the working tree either way. The assertion is the backstop for exactly this case.
 
 The file discloses **direct** dependencies only. The complete npm closure with pinned versions already lives in `pnpm-lock.yaml` (`pnpm licenses list` renders it) and the Python closure in `python/sdk/uv.lock`; re-materializing either as prose would be a second, worse copy.

 **Concurrent views converge without stale replacement.** The acknowledgement write omits `expectedRevision` deliberately: every tab writes the same version to one path, so the operation is idempotent and preserves sibling fields instead of rebuilding the section. `settings/document-updated` becomes `host/settings-changed`; an already mounted tab refetches and advances when another tab or an external editor commits the current version. The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.
 
-**The welcome modal is scan-first and has one completion path.** Its hierarchy is a declaration title, one status sentence, one emphasized feedback callout, one consequence sentence, and a restrained quotation; the notice version changes whenever that authored copy changes materially. It renders no close icon or secondary action, installs no Escape handler, and assigns no click handler to the mask. Its mask starts below the 80 px top chrome and preserves `position:absolute`, zero left/right/bottom offsets, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Continue is the sole button and receives initial focus.
+**Onboarding temporarily owns the viewport as one continuous stage.** A solid product surface replaces the complete application view through a body-level portal and marks the underlying app root inert; the exact required mask remains mounted behind that surface with `position:absolute`, zero left/right/bottom offsets, `top:80px`, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Welcome and conditional credential setup render as successive pages in this stage instead of independent modals. Both pages reuse the Web UI's black `BrandWordmark`. The welcome page preserves the four authored paragraphs verbatim under the `内测声明` title; every paragraph uses one 16/28 body scale, and only the requested action clause inside the final paragraph receives a subtle 500 weight. A short staggered opacity/vertical entrance supplies pacing without blocking interaction and disappears under reduced motion. The title receives initial focus, Continue is the sole button, and no close, Escape, or mask-click path exists.

 **并发视图无需陈旧的整体替换即可收敛。** 确认写入有意省略 `expectedRevision`：每个标签页都向同一路径写入相同版本，因此该操作是幂等的，并会保留同级字段，而不是重建整个分节。`settings/document-updated` 会转为 `host/settings-changed`；另一个标签页或外部编辑器提交当前版本后，已挂载的标签页会重新拉取状态并推进。API 网关在可配置提供方 namespace 之外，通过封闭的允许列表暴露这一个产品 namespace，同时不会把它的变更视为模型目录失效事件。
 
-**欢迎模态窗口以便于扫读为先，且只有一条完成路径。** 其信息层级依次为声明标题、一句状态说明、一则重点突出的反馈提示、一句影响说明和一则克制的引语；只要这份文案发生实质变化，就同步提升通知版本。界面不渲染关闭图标或次要操作，不安装 Escape 处理器，也不为遮罩添加点击处理器。遮罩从顶部 80 px 的界面框架下方开始，并保留 `position:absolute`、left/right/bottom 偏移量为零、`rgba(0, 0, 0, 0.24)` 和 `backdrop-filter: blur(2px)`。「继续」是唯一按钮，并会获得初始焦点。
+**引导流程会暂时接管视口，形成一个连续阶段。** 纯色产品界面通过挂载到 `body` 的 portal 取代完整的应用视图，并将底层应用根节点标记为 inert；严格符合要求的遮罩仍挂载在该界面后方，并保留 `position:absolute`、left/right/bottom 偏移量为零、`top:80px`、`rgba(0, 0, 0, 0.24)` 和 `backdrop-filter: blur(2px)`。欢迎页和按条件显示的凭据设置页在这一阶段中依次呈现，而不是各自作为独立的模态窗口。两个页面都复用 Web UI 的黑色 `BrandWordmark`。欢迎页在 `内测声明` 标题下逐字保留既定的四段文案；所有段落统一采用 16/28 的正文字号与行高，只有最后一段中指定的行动语句使用较为克制的 500 字重。短暂的错落式透明度与纵向位移动画营造出舒缓节奏，但不会阻碍交互，并会在用户启用减少动态效果时禁用。初始焦点落在标题上，「继续」是唯一按钮，且不存在关闭、Escape 或点击遮罩的退出路径。

 Settings ownerless-copy and product-onboarding plugin: registers everything on the Settings surface that belongs to no single feature — the shell's trigger/header/close chrome content, the General section (Permission/Tool Call skeleton rows + the `settings.general.item` slot declaration), the `settings` dictionaries, and the first ordered welcome step. Feature-owned rows (Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.
 
-`src/onboarding-copy.ts` is the single editable owner of the complete Chinese and English notice plus `WELCOME_NOTICE_VERSION`. The Host half registers `ui-onboarding` in the user-settings seam; the browser compares `welcomeNoticeVersion` for exact equality and writes the current value only after Continue succeeds. The path mutation is idempotent across tabs and preserves sibling settings, while `host/settings-changed` makes an externally acknowledged notice advance without a reload. A different version deliberately presents the notice again. The welcome UI has no close, Escape, mask-click, or secondary path, and none of its copy or acknowledgement enters a Session log or model request.

+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.

 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.

 ## Why DeepSeek Harness
 
-Built-in capabilities cover file reading, editing, and search; shell and persistent PTY execution; reusable skills; task tracking, goals, plans, todos, and background tasks; subagents and workflows; sandboxing and approvals; persistent, resumable, forkable, and queryable sessions; LSP and web access; context compaction; and telemetry. Each composition selects the subset appropriate to its surface. The TUI also includes Plan Mode.
+Built-in capabilities cover file reading, editing, and search; shell and persistent PTY execution; reusable skills; task tracking, goals, plans, todos, and background tasks; subagents and workflows; sandboxing and approvals; settings and credentials; persistent, resumable, forkable, and queryable sessions; LSP and web access; context compaction; and telemetry. Each composition selects the subset appropriate to its surface. The TUI and Web UI both include Plan Mode.
 
 - **Everything is a plugin.** Models, tools, policies, storage, context management, and interfaces are composable [Cordis plugins](docs/user/develop/basic/index.md), so deployments can extend or replace behavior without forking the agent loop. See the [architecture](docs/architecture.md) for the underlying design.
 - **Runs are reconstructable.** Anything visible to the model is logged in the authoritative session stream; persistence, resume/fork/query, replay, telemetry, and UIs derive from the same events. See the [session-log architecture](docs/architecture.md#session-log).
