+# Agent Note: Timed user questions as two settlements
+
+Status: proposed
+
+English | [中文](2026-09-19-timed-user-question-two-settlements.zh.md)
+
+## Problem
+
+A question can block an agent even when useful work does not depend on the answer. Releasing the tool call after a wait must not discard the question: the user may answer after the agent has continued or after reopening the Session. A pending result is neither a skipped answer nor permission to proceed with work that requires approval.
+
+The foreground tool result and the eventual answer have different lifetimes. A `user-questions/request` waterfall settles once; keeping it alive after returning pending creates a second answer path that outlives its caller. Countdown, focus, and editing also have different owners from durable question state.
+
+## Proposal
+
+Keep foreground answers on the existing Remote Event waterfall. A timeout ends that request and returns pending; a later answer uses a business RPC that steers a durable user message. The claim stream controls the foreground wait only. It neither transports answers nor replaces the Remote Event.
+
+### Modes and scope
+
+- The default `mode: legacy` retains the blocking schema and `ask()` path. Explicit `mode: timed` adds `timeout`, using the configured default of 120 seconds when omitted.
+- A positive integer timeout selects `askTimed()`; `-1` selects blocking `ask()`. A blocking call made with the timed schema still participates in timed-question projection and review; it is not identical to a legacy call.
+- Plan review retains `ask()`, its `plan-review` intent, and `BAD_INTENT` validation. This decision does not move plan review to another package.
+- Human interaction requires the exact live runtime root when an Agent is supplied. A stale instance fails with `CALLER_NOT_LIVE`; an owned child fails with `DELEGATED_CALLER`. Durable Session lineage does not prevent a resumed runtime root from asking.
+
+### Ownership
+
+| Owner | Responsibility |
+|---|---|
+| `tool-ask-user` | Model schema, timeout validation, service selection, and pending-result text. |
+| `UserQuestionService` | Foreground waits and Client claims, unattended deadlines, late-answer validation and steering, and the durable question projection. |
+| Gateway and Remote runtime | Existing request delivery, settlement, cancellation, and Remote stream transport; no question-specific timer or event-name branch. |
+| `ui-user-questions` | One card per Session and call, answer-channel selection, local countdown and drafts, and the reply Definition and renderer. |
+| `ui-chat` | Message-id-based presentation aggregation and ordinary process/Turn folding. |
+| Question-specific tool row | Pending/answered presentation and panel actions, composed in `QuestionToolRow` without adding `rowAction` to generic `ToolRow`. |
+
+The [question service](../../../../packages/interaction/user-questions/README.md), [tool](../../../../packages/interaction/tool-ask-user/README.md), and [questions UI](../../../../packages/client/ui-user-questions/README.md) own their package contracts.
+
+### Foreground wait and claim lifetime
+
+`TimedQuestionWait` owns a private cancellation signal, the original Host deadline, and Client claims. The Host runs a timer only while no answer UI holds a claim. Delivery to a transport queue is not a claim. Losing the last claim restores the original deadline, with immediate expiry if it has passed.
+
+A timed request carries `wait: { callId, timed: true }`. Before attaching its answer channel, the Client opens `attachWait`, a business Remote stream that yields one Host-computed `remainingMs` frame and stays open for the claim's lifetime. Focus, edits, and heartbeats do not travel through this stream.
+
+The Client retains its claim through delivery of the waterfall outcome to the Host. Returning an answer locally is not delivery: releasing the claim then could let an overdue Host timer beat that answer. The Host closes the claim when the foreground request settles. Explicit delegation releases the claim before `next()`; plugin teardown delegates and cancels its stream.
+
+Client countdown expiry rejects the waterfall with `ASK_TIMED_OUT`. Unattended Host expiry aborts only the private wait signal with the same business error. `askTimed()` maps only that error to pending, maps parent cancellation to `ASK_ABORTED`, and propagates other failures. `NO_PROVIDER` waits on the same bounded wait lifetime, not a permanently unresolved promise. Foreground completion releases timers, claims, and the wait registry entry.
+
+### Durable state and late answers
+
+The `userQuestions` projection reconstructs question state from existing Session events. It recognises the timed schema by the `timeout` parameter recorded in `request/header`; legacy calls are not tracked. A valid `tool/call` opens a question. Its `tool/result` makes it continued for pending or `TOOL_OUTCOME_UNKNOWN`, settles it with a valid answer batch, or removes it for another result or failure.
+
+A continued question accepts `answer(agent, callId, answer)`. The method returns `false` for an unknown or non-continued call and throws `BAD_ANSWER` unless the batch names each question exactly once. Accepted answers use `agent.steer(createUserMessage(...))`, source `{ kind: 'user-question-reply', callId, outcome: 'answered' }`, and JSON text containing `answer_to_pending_question`, the call id, original questions, and answers. Remote Agent resolution from the Session id resumes a root when needed; the `answer()` body does not own that resume operation.
+
+The inbox message is the durable reply. `agent/inbox/spliced` settles the question when the message is queued; the later admitted `user/message` is idempotent for that settlement. Settled answer batches remain in the projection so the original tool row can show late answers even though its own result remains pending. Unusable recorded reply text settles with an empty batch.
+
+No new Session event type or wait-state log is needed. The message-source extension requires the repository's persistence-type acknowledgement. `dismissed` remains readable for historical records but has no producer: hiding a panel does not manufacture a reply.
+
+### Card state and delivery races
+
+`QuestionCards` shares one `PendingQuestion` between the live request and the continued projection, keyed by Session and `callId`. A blocking request without a call id has its own per-request card. An open card submits through its waterfall; without that channel it disables submission. A continued card uses the late-answer RPC.
+
+A waterfall submission has no delivery acknowledgement. The Gateway can discard an outcome that loses a settlement race. The card therefore retains its draft and stays busy until projection reconciliation. If the question becomes continued during submission, the controls re-arm with a resubmit hint; the user can submit the retained draft through RPC. This is not automatic retry or a guarantee that every local submission reaches the model.
+
+A tool-call-keyed card is removed when its call is absent from the active projection and no waterfall remains. Removal closes the card and clears its draft. Neither a local submission nor a transport cancel frame alone decides that the question is answered. An unkeyed blocking card ends with its waterfall; closing that blocking panel rejects with `ASK_CANCELLED`.
+
+### Local countdown and panel actions
+
+The Client computes `Date.now() + remainingMs`. Manual focus on a pristine answer surface pauses its countdown, and blur resumes the preserved remainder. Focus before the claim handshake remains effective when the deadline arrives; blur before the handshake does not create a timer. First edit or Take time freezes the countdown, with that disposition saved beside the browser-local draft.
+
+Autofocus applies only when the answer channel is ready, no countdown is active, and the card is not locked. Hiding a timed-call panel leaves its claim and countdown running; its tool row can reopen it. A settled call opens a read-only panel from recorded questions and answers, not another answer channel.
+
+### Reply node and grouping
+
+The questions UI identifies a late reply from `source.kind`, then parses its recorded JSON for question-and-answer presentation. Pasting identical JSON in an ordinary user message does not identify it as a reply. Unreadable recorded payloads retain their raw-text presentation.
+
+The ordinary message Definition and the question-reply Definition both match the appended message and retain separate Node Store projections with the same message id. Chat business grouping omits the `turn-trigger` presentation when a `question-reply` with that id is present. The duplicate trigger neither renders nor splits a group; the reply renders once. The same aggregation applies to unscoped historical input.
+
+The reply participates in ordinary process grouping and whole-Turn folding. It is not independently visible: reading it can require expanding both its Turn and process group. Turn disclosure stays before the group it controls, including a reply that opens the Turn.
+
+This decision adds no process-role field, independent-layout flag, user-message structure change, or target-local fallback dispatch. The independent-kind rules stay in Chat's existing grouping logic. A node-data-owned declaration of grouping and overlap semantics is deferred infrastructure, not part of the question feature.
+
+## Alternatives considered
+
+**Unconditional Host deadline or Gateway-owned question timers.** An unconditional deadline overrides local editing and Take time. Putting the exception into pending Remote Events or branching on the question event in Remote dispatch makes generic transport own business policy. Claims keep that policy in the question service.
+
+**Keep the waterfall alive after returning pending.** The request outlives the tool caller, and late waterfall answers compete with the RPC. Ending the foreground request gives each settlement one answer path.
+
+**Delegate every timed request immediately.** Dispatching to an intentionally empty answerer set wastes the existing blocking-answer path and requires special handling of `NO_PROVIDER`. Delegation is for an unavailable answerer, not the timed mode itself.
+
+**Persist a whole-value wait/focus/edit stream or use Host focus leases.** Durable question status is derivable from tool and inbox events. Focus and editing are local UI state; logging them or synchronising focus leases adds Host state without making multiple Clients share one editing session.
+
+**Reclassify JSON inside generic `MessageItem`, borrow the relay form, or use the default context row.** Parsing text to identify the business message confuses its source with its content; the relay form describes another agent's message, and a generic context row exposes JSON. A dedicated source, Definition, and renderer own the question presentation.
+
+**Independent reply layout through generic node metadata.** It broadens a question feature into a conversation-infrastructure change. Ordinary folding and Chat-owned aggregation are sufficient for this decision; independently declared node-data grouping semantics remain a separate design task.
+
+**A log-only close event or a manufactured dismissal message on panel close.** A log-only close hides the user's decision from the model and adds another durable mechanism. Manufacturing a reply treats hiding the panel as an answer. Panel close therefore leaves a timed question answerable.
+
+**A dedicated late-reply Session event beside the inbox message.** The inbox splice and admitted user message already record the reply. A third event duplicates the same fact and adds another persistence type.
+
+## Acceptance criteria
+
+- Service tests cover claimed and unclaimed waits, last-claim disconnect, cancellation, timeout error mapping, continued-only answers, and exact answer-id validation.
+- Projection tests distinguish legacy and timed schemas and cover pending, answered, other failures, resume repair, and duplicate inbox/message settlement.
+- Client tests cover claim retention through Host acceptance, focus before handshake, indefinite waits, draft retention, RPC resubmission, and panel hiding/reopening.
+- Grouping and browser replay cover one rendered reply with both projections retained, ordinary collapsed placement, disclosure ordering, and the original tool row's read-only late-answer panel.
+- Legacy question round trips, cancellation, plan-review intent, and Session remounts retain their existing behavior. Live multi-Client delivery races and real Host restart remain integration coverage gaps beyond isolated lifecycle and projection tests.
+
+## Risks
+
+- Take time affects only one Client. Another Client can answer or expire the shared waterfall; local focus does not establish a global hold.
+- A terminal claim-stream failure can reject the foreground question rather than produce pending. No unattended-wait fallback is provided for that failure.
+- Host and Client clocks need not align, but Client system-clock changes can move expiry and transport latency can delay the local countdown's start.
+- The duplicate projections remain stored. Aggregation adds linear scans during structural grouping rebuilds; ordinary text-only streaming updates retain their incremental path. This is an algorithmic bound, not a measured latency claim.
+- Unanswered continued questions can remain after reopening a Session. Panel close records nothing, and visibility follows normal folding rather than an always-visible reply guarantee.

+# Agent Note: 计时用户提问的两次结算
+
+Status: proposed
+
+[English](2026-09-19-timed-user-question-two-settlements.md) | 中文
+
+## Problem
+
+即使还有不依赖回答的工作可做，问题仍可能阻塞 agent（智能体）。等待后放行工具调用不能丢弃问题：用户可能在 agent 继续执行后，或重新打开 Session 后才回答。pending 结果既不是跳过回答，也不是开展需要批准的工作的授权。
+
+前台工具结果与最终回答的生命周期不同。`user-questions/request` waterfall（瀑布式事件）只结算一次；返回 pending 后仍保留它，会产生一条活过调用方的第二回答路径。倒计时、聚焦和编辑的归属也不同于持久问题状态。
+
+## Proposal
+
+前台回答继续使用现有 Remote Event waterfall。超时结束该请求并返回 pending；迟到回答通过业务 RPC steer 一条持久用户消息。接手 stream 只控制前台等待，既不传递回答，也不替代 Remote Event。
+
+### 模式与范围
+
+- 默认 `mode: legacy` 保留阻塞式 schema 和 `ask()` 路径。显式 `mode: timed` 增加 `timeout`，省略时使用配置默认值 120 秒。
+- 正整数超时选择 `askTimed()`；`-1` 选择阻塞式 `ask()`。timed schema 发出的阻塞调用仍参与计时问题投影和答案查看，并不等同于 legacy 调用。
+- 计划评审保留 `ask()`、`plan-review` 意图及 `BAD_INTENT` 校验。本决策不把计划评审迁移到其他包。
+- 提供 Agent 时，人机交互要求它是运行时中确切的存活根实例。陈旧实例以 `CALLER_NOT_LIVE` 失败；被其他 agent 拥有的子实例以 `DELEGATED_CALLER` 失败。持久 Session 的血缘关系不妨碍恢复后的运行时根实例提问。
+
+### 职责归属
+
+| 归属方 | 职责 |
+|---|---|
+| `tool-ask-user` | 模型 schema、超时校验、服务选择和 pending 结果文本。 |
+| `UserQuestionService` | 前台等待与 Client 接手、无人接手时的 deadline、迟到回答校验与 steering（中途引导），以及持久问题投影。 |
+| Gateway 与 Remote 运行时 | 现有请求投递、结算、取消及 Remote stream 传输；不包含问题专属计时器或按事件名分支。 |
+| `ui-user-questions` | 每个 Session 和调用的一张卡片、回答通道选择、本地倒计时与草稿，以及回复 Definition 和渲染器。 |
+| `ui-chat` | 基于消息 id 的呈现聚合，以及普通过程／轮次折叠。 |
+| 问题专用工具行 | pending／已回答呈现与面板操作，在 `QuestionToolRow` 中组合，不向通用 `ToolRow` 添加 `rowAction`。 |
+
+[问题服务](../../../../packages/interaction/user-questions/README.zh.md)、[工具](../../../../packages/interaction/tool-ask-user/README.zh.md)和[问题 UI](../../../../packages/client/ui-user-questions/README.zh.md)分别拥有各包的约定。
+
+### 前台等待与接手生命周期
+
+`TimedQuestionWait` 拥有专属取消 signal、原始 Host deadline 和 Client 接手记录。Host 只在没有回答 UI 接手时运行计时器。投递到传输队列不算接手。最后一个接手方离开后恢复原 deadline，已经过期则立即到期。
+
+计时请求携带 `wait: { callId, timed: true }`。Client 在挂接回答通道前打开业务 Remote stream `attachWait`，接收一帧由 Host 计算的 `remainingMs`，并在接手期间保持 stream 打开。聚焦、编辑和心跳不经过该 stream。
+
+Client 将接手保留到 waterfall 结果交付给 Host。本地返回回答不等于交付：此时释放接手会让已经到期的 Host 计时器抢在回答之前结算。Host 在前台请求结算时关闭接手。显式委托在 `next()` 前释放接手；插件拆卸会委托请求并取消自己的 stream。
+
+Client 倒计时到期以 `ASK_TIMED_OUT` 拒绝 waterfall。无人接手时，Host 到期只以同一业务错误中止等待专属 signal。`askTimed()` 只把该错误映射为 pending，把父级取消映射为 `ASK_ABORTED`，其余失败继续传播。`NO_PROVIDER` 等待同一个有界等待生命周期，而不是永不结算的 Promise。前台完成时释放计时器、接手记录及等待注册项。
+
+### 持久状态与迟到回答
+
+`userQuestions` 投影从现有 Session 事件重建问题状态。它通过 `request/header` 记录的 `timeout` 参数识别 timed schema，不跟踪 legacy 调用。有效的 `tool/call` 打开问题。其 `tool/result` 在 pending 或 `TOOL_OUTCOME_UNKNOWN` 时将问题标为已继续，在有效回答批次时结算并保存答案，其他结果或失败则移除问题。
+
+已继续的问题接受 `answer(agent, callId, answer)`。未知或非已继续调用返回 `false`；回答批次没有恰好包含每个问题一次时抛出 `BAD_ANSWER`。接受的回答通过 `agent.steer(createUserMessage(...))` 送入 agent，来源为 `{ kind: 'user-question-reply', callId, outcome: 'answered' }`，JSON 文本包含 `answer_to_pending_question`、调用 id、原问题及答案。Remote 根据 Session id 解析 Agent 时按需恢复根实例；恢复操作不属于 `answer()` 方法体。
+
+inbox 消息就是持久回复。`agent/inbox/spliced` 在消息入队时结算问题；随后接纳的 `user/message` 对该结算是幂等的。已结算答案批次保留在投影中，让原工具行即使自身结果仍是 pending，也能显示迟到回答。无法使用的已记录回复文本以空答案批次结算。
+
+无需新增 Session 事件类型或等待状态日志。消息来源扩展需要仓库的持久化类型变更确认。`dismissed` 为历史记录保留可读性，但没有生产者：隐藏面板不会伪造回复。
+
+### 卡片状态与投递竞争
+
+`QuestionCards` 按 Session 和 `callId`，让实时请求与已继续投影共享一个 `PendingQuestion`。没有调用 id 的阻塞请求拥有独立的逐请求卡片。开放卡片通过 waterfall 提交；缺少该通道时禁用提交。已继续卡片使用迟到回答 RPC。
+
+waterfall 提交没有送达确认。Gateway 可能丢弃输掉结算竞争的结果，因此卡片保留草稿并保持忙碌，等待投影同步。若提交期间问题变为已继续，控件带重提提示重新可用，用户可以通过 RPC 提交保留的草稿。这不是自动重试，也不保证每次本地提交都能到达模型。
+
+按工具调用标识的卡片在调用不属于活动投影且没有 waterfall 时移除。移除会关闭卡片并清理草稿。本地提交和传输取消帧都不能单独决定问题已经回答。无调用标识的阻塞卡片随 waterfall 结束；关闭这种阻塞面板以 `ASK_CANCELLED` 拒绝请求。
+
+### 本地倒计时与面板操作
+
+Client 计算 `Date.now() + remainingMs`。手动聚焦未编辑的回答区会暂停倒计时，失焦后从保留的剩余时间继续。接手握手前的聚焦在 deadline 到达时仍生效；握手前失焦不会制造计时器。首次编辑或「慢慢回答」冻结倒计时，该状态与浏览器本地草稿一起保存。
+
+只有回答通道就绪、没有活动倒计时且卡片未锁定时才自动聚焦。隐藏计时调用的面板会保留接手和倒计时，工具行可以重新打开面板。已结算调用依据记录的问题与答案打开只读面板，不产生另一条回答通道。
+
+### 回复节点与分组
+
+问题 UI 通过 `source.kind` 识别迟到回复，再解析已记录的 JSON 来呈现问答。普通用户消息粘贴相同 JSON 不会被识别为回复。无法读取的已记录载荷保留原始文本呈现。
+
+普通消息 Definition 和问答回复 Definition 都匹配追加的消息，在 Node Store 中保留消息 id 相同的独立投影。存在同 id 的 `question-reply` 时，Chat 业务分组省略 `turn-trigger` 呈现。重复触发节点既不渲染，也不切开分组，回复只显示一次。相同聚合也适用于无轮次归属的历史输入。
+
+回复参与普通过程分组和整轮折叠，不保证独立可见：阅读时可能需要展开所属轮次与过程分组。轮次折叠控件始终在所控制的分组之前，包括由回复开启轮次的情况。
+
+本决策不添加 process-role 字段、独立布局标记、用户消息结构变更或目标内 fallback 派发。独立 kind 规则保留在 Chat 现有分组逻辑中。由节点 data 声明分组与重叠语义的机制是留待拆分的基础设施，不属于问题功能。
+
+## Alternatives considered
+
+**无条件 Host deadline 或 Gateway 拥有问题计时器。** 无条件 deadline 会覆盖本地编辑和「慢慢回答」。把例外放入 pending Remote Events，或在 Remote 派发中按问题事件分支，会让通用传输拥有业务策略。接手机制将策略留在问题服务中。
+
+**返回 pending 后继续保留 waterfall。** 请求活过工具调用方，迟到的 waterfall 回答与 RPC 竞争。结束前台请求让每次结算各有一条回答路径。
+
+**立即委托所有计时请求。** 向故意留空的回答方集合派发请求，浪费现有阻塞回答路径，还要求特殊处理 `NO_PROVIDER`。委托表示回答方不可用，不代表计时模式本身。
+
+**持久化整值等待／聚焦／编辑流，或使用 Host 聚焦租约。** 持久问题状态可从工具与 inbox 事件推导。聚焦和编辑属于本地 UI 状态；记录它们或同步聚焦租约会增加 Host 状态，却不能让多个 Client 共享同一编辑会话。
+
+**在通用 `MessageItem` 内重新分类 JSON、借用 relay form，或使用默认 context 行。** 解析文本来识别业务消息混淆了来源与内容；relay form 表示其他 agent 的消息，通用 context 行则会暴露 JSON。专用来源、Definition 和渲染器拥有问题呈现。
+
+**通过通用节点元数据让回复独立布局。** 这会把问题功能扩大为对话基础设施变更。普通折叠与 Chat 内聚合足以满足本决策；由节点 data 独立声明分组语义仍是单独的设计任务。
+
+**面板关闭时写仅入日志的关闭事件，或伪造放弃消息。** 仅入日志会让模型看不到用户决定，还增加另一套持久机制。伪造回复则把隐藏面板当成回答。因此关闭面板仍让计时问题保持可回答。
+
+**在 inbox 消息之外增加专用迟到回复 Session 事件。** inbox 插入与接纳的用户消息已经记录回复。第三个事件重复同一事实，并增加另一种持久化类型。
+
+## Acceptance criteria
+
+- 服务测试覆盖有人与无人接手、最后接手方断开、取消、超时错误映射、仅接受已继续问题的回答，以及答案 id 的精确校验。
+- 投影测试区分 legacy 与 timed schema，并覆盖 pending、已回答、其他失败、恢复修复及 inbox／消息重复结算。
+- Client 测试覆盖接手保留到 Host 接受结果、握手前聚焦、无限期等待、草稿保留、RPC 重提及面板隐藏／重开。
+- 分组与浏览器回放覆盖保留两个投影但只渲染一次回复、普通折叠位置、折叠控件顺序，以及原工具行的迟到答案只读面板。
+- legacy 问答往返、取消、计划评审意图及 Session 重新挂载保留既有行为。真实多 Client 投递竞争与真实 Host 重启仍是独立生命周期和投影测试之外的集成覆盖缺口。
+
+## Risks
+
+- 「慢慢回答」只影响一个 Client。其他 Client 可以回答或让共享 waterfall 到期，本地聚焦不构成全局暂停。
+- 接手 stream 的终止性失败可能让前台问题失败，而不是产生 pending。不为该失败提供无人接手等待的 fallback。
+- Host 与 Client 时钟不必对齐，但 Client 系统时钟变化可能移动到期时间，传输延迟可能推迟本地倒计时的开始。
+- 重复投影仍保留在存储中。聚合在结构性分组重建时增加线性扫描；普通纯文本 stream 更新保留增量路径。这是算法复杂度界限，不是实测延迟结论。
+- 无人回答的已继续问题可以在重新打开 Session 后继续存在。关闭面板不写记录，可见性遵循普通折叠，而不是保证回复始终可见。

+Web and desktop share the [Coding Tools preference](../../packages/client/ui-settings/README.md#use-this-package). It controls diagnostic Views, new-session preset selection, changed-file cards, and the builtin HTML preview policy without changing Session records.
 
 `ui-session` installs the Session scope adapter and publishes `useSessions`, `useSessionStatus`, `useSessionRetainInfo`, `useSession`, `sessionId`, and `useProjection`. `SessionProvider` inherits an outer binding or binds an explicit `SessionReference`, so concurrent subtrees can target different Sessions. Domain adapters add further standard sources without putting React hooks on the model objects.

 `ui-session` 安装 Session scope adapter，并提供 `useSessions`、`useSessionStatus`、`useSessionRetainInfo`、`useSession`、`sessionId` 和 `useProjection`。`SessionProvider` 可以继承外围 binding，也可以绑定显式 `SessionReference`，因此并存子树可以指向不同 Session。领域 adapter 可以继续添加标准 source，但不会把 React hook 放进 model object。

 Settings shows the built-in and custom card groups with default highlighting and card-body selection; a group without presets is omitted, except the custom group, which keeps its Creator entry on screen. Every card offers “View configuration”, which opens the preset's declared plugin list as read-only YAML in the Loader's own dialect (`!!js` conditions included); a failed preset stays readable because its diagnostic points into that YAML. Escape closes only the viewer and returns focus to its card; leaving Settings clears the viewer, and a late read does not reopen it. The page edits nothing: the Creator entry starts a Creator-mode task that authors or overrides a preset as a bundle, offered while the `cordis` preset is on the roster and a conversation flow exists.

Choosing a healthy default also synchronizes the blank session on the current new-task surface. Creator starts a new task using the `cordis` preset.
 
 Known shipped presets offer mode details and usage examples in a read-only dialog. Its tabs preserve each page's scroll position; closing returns focus to the opening action. Help does not change the new-task default. The default badge replaces the card's group badge, and the preset id appears beside the title. Guide copy and examples belong to this package.

+Coding Tools must be enabled to show this card or request its summary. Turning the preference off removes the card immediately while explicit delivery cards, inline file links, and recorded workspace changes remain available.
 
 The card renders the summary the Host serves for the turn's latest `workspace/changes` announcement, read once per announcement through the authenticated summary route; while the read is pending, once the Host answers that the summary is gone, or when it lists no file, there is no card. A single changed file shows “Edited” and its basename with its file-type icon, without a file list; its header retains the counts or binary/oversized status and the file’s accessible full path. Multiple files use a code-file icon and a header naming the complete changed-file count and summed added and deleted lines; hovering or focusing it replaces the counts with “Preview in sidebar”. Each row shows one file's display path in the regular UI font with its own monospace counts, “binary” for a binary file, or “too large” for a file the Host did not capture. Rows appear in the recorded display order, so repository files above the working directory and files outside it sort first. Four rows show before a fold; the control reveals every recorded file and, once expanded, collapses the list again from the bottom. Each row opens the turn's review in the right Sidebar on that file, and the header opens it on the first file. Hovering a file row or the single-file header for 500ms opens a scrollable, single-column preview of the comparison, independent of the Sidebar’s view. Its full path uses muted monospace text and scrolls horizontally when needed. File-status notes accompanying code and hunk headers are hidden in the preview; comparisons without hunks retain their status text. Each row exposes the full path as its accessible description. The preview is 48px narrower than the card, inset 24px on each side, and at most 420px high, further constrained by the viewport. The whole preview fades in and out over 100ms. Moving into the preview keeps it open; leaving it, pressing Escape, or activating the row by pointer or keyboard dismisses it. Comparisons load only when the preview opens and share the review tab’s cache and retry states.

 #### What the model sees
 
-The guidance prefers primary results in the final reply: inline images support explanations and comparisons, image links serve references and file lists, and image file cards serve separate deliverables. File destinations use angle brackets, including paths with spaces. It recommends separate `present` cards for complete file deliverables, especially Office files, usually selecting the most important one or two, with at most four files per call when more are needed. It discourages cards solely for code edits and extra commands to inspect diff visibility. This guidance applies even with developer tools disabled: it accepts fewer file surfaces to avoid duplicate presentation and unnecessary tool calls. It asks the model to link every existing-file mention outside commands, configuration expressions, and code blocks, including repeats and tables. Labels default to filenames or clear aliases, with only enough parent directories to distinguish files. Precise references display `filename:24` or `filename:24–30`; their destinations retain full relative or absolute paths with `#L24` or `#L24-L30` anchors. The display suffix contains neither `#` nor `L`.

 The rows are disabled while a save is in flight, while the catalog is loading, during a deletion, and for an inactive task. A save bar appears only while the local draft differs from the stored task: it shows Unsaved changes with Cancel and Save changes, and Save changes becomes Saving… while the save is in flight. Cancel restores the stored values. A catalog refresh becomes the shown values only while the draft has no unsaved edit, so an unsaved draft survives an authoritative refresh. A failed save keeps the draft and shows a localized message; after a conflict, retry against the refreshed record. If the task disappears from the catalog, Delete is disabled until the task returns. A successful update refreshes the authoritative catalog. A rejected or unconfirmed update is distinct from a catalog-read failure: Retry reloads the catalog without presenting the update as failed. If the update itself cannot be confirmed, check the task before retrying. Late responses after switching tasks or closing details do not replace the current view, and no failure rolls back a Host write already begun.

Each Saved delivery record leads with a clock glyph and its occurrence time as the locale's month name and clock field pair in the task's zone, or the browser's zone for a one-shot record, and shows the actual saved prompt when present. A prompt longer than two lines shows its first two lines and an Expand toggle, which Collapse reverses; a collapsed prompt rechecks its length when the panel width changes. A legacy receipt without a prompt never substitutes the current instruction.
 
 After the last saved page loads, a nonempty history with confirmed pruning shows a borderless notice at the bottom left of the detail panel. Its info button expands or collapses the current Host retention rules. Empty history, legacy unavailability without confirmed pruning, incomplete pagination, and failed reads show no cleanup notice.

-The welcome page requires Get started. The credit page always appears. A positive balance confirmed at first entry selects Continue as the primary action and Add credits as the secondary action. This choice stays fixed until the onboarding controller is recreated and is never persisted; late balance results cannot change the buttons. Only a confirmed absence of positive credit adds a confirmation before continuing without recharge; pending or failed queries do not block continuing. Purpose descriptions remain unchanged when selected. Returning from the native top-up view keeps the credit page and re-reads profile and balance in the background after any read already running, whether loading or payment succeeded. That read does not recompute the funded-mode choice, so a completed recharge leaves the buttons as first entered while continuing still evaluates the refreshed balance. Next confirms only a known zero balance; Skip uses the credit warning on the credit page and the setup warning on the question pages. Office-only use completes with compact presentation; development or both purposes also ask for process detail. Back preserves selections, and explicit skip from any supported step applies standard process, compact performance/usage, and disabled developer tools. This flow creates no workspace or demonstration task.

Returning from the native top-up view keeps the credit page and re-reads profile and balance in the background after any read already running, whether loading or payment succeeded. That read does not recompute the funded-mode choice, so a completed recharge leaves the buttons as first entered while continuing still evaluates the refreshed balance. Next confirms only a known zero balance; Skip uses the credit warning on the credit page and the setup warning on the question pages. Office-only use completes with compact presentation; development or both purposes also ask for process detail. Back preserves selections, and explicit skip from any supported step applies standard process, compact performance/usage, and disabled Coding Tools. This flow creates no workspace or demonstration task.

 ## Understand the implementation
 
 The Account section appears first in Settings only while signed in; it is hidden before account state loads and after sign-out. The plugin owns one Host snapshot stream shared through framework hooks by settings.section and settings.launcher. The launcher opens Settings and offers Sign out only while an account credential is stored. Platform failures leave the menu available for retry. It maintains no independent credential state, so no invariant companion is published.
 
-The desktop controller writes progress to `ui-settings-account` through Host settings. Completion first applies `ui-chat.transcriptView` and `ui-chat.performanceUsage` together, then calls the shared developer-tools preference to persist `ui-settings.enabled`, and finally saves the done marker; a rejected write keeps the flow available for retry. Successful completion reveals the workspace through a 180ms fade; choices and ordinary navigation preview immediately while writes run in order. A failed final queued write restores saved progress and allows retry. Completion waits for queued choices and retains the page until preferences persist; reduced motion skips the fade. Onboarding choices compact, standard, and detailed apply directly to the corresponding Chat work-detail modes. API-key entry and explicit skip select standard; onboarding does not select verbose. Complete Figma illustration layers are bundled as transparent, palette-compressed 3× PNG assets; welcome layers are merged with local sidebar blur; recharge uses a 70% opaque foreground window with local blur of the covered illustration, and headings use the bundled Montserrat brand font; English headings and descriptions use Light (300), except the DeepSeek Harness brand within headings uses Medium (500); card titles retain Regular (400) when selected. English footer navigation uses Light (300). Confirmed onboarding sets a 960px minimum window width and enlarges narrower windows; completion releases the minimum without restoring the previous size. Loading or already-completed onboarding does not resize the window. Empty footer navigation space passes pointer events through to the primary action. Cards exclude native window dragging and own the keyboard focus outline for their checkbox. The account package owns its onboarding overlay and control geometry. Each step and the confirmation dialog has a separate component; the flow coordinates navigation, transitions, and recharge. The overlay hides the workspace while initial account and progress state loads. Question headings and cards follow the Figma positions at 1440 × 920 and 960 × 600, independently of their action buttons. On macOS, content clears the body portal’s inherited no-drag region and a first-child drag band leaves an 8px native resize margin; interactive controls and later dialogs exclude their regions, and a native Platform page disables the underlying onboarding band. The upper workspace popup illustration has an opaque background in both languages and themes; the underlying sidebar omits its selected-row highlight. Welcome keeps its illustration at its original size, repositions and clips the artwork in narrow windows, and reveals the complete illustration on wide windows. The [onboarding decision](../../../.agents/notes/implemented/feature/2026-09-16-desktop-onboarding.md) owns persistence and presentation trade-offs.

 ## 理解实现
 
 仅登录后在设置导航首位显示账号页；账号状态加载完成前以及退出登录后隐藏该页。 插件持有一条 Host 快照流，通过框架 hook 供 settings.section 和 settings.launcher 共享。入口菜单可打开设置，并仅在已存储账号凭证时提供退出登录。Platform 请求失败时保留菜单，以供重试。插件不维护独立凭证状态，因此不发布 invariant。

 The section declares two seats for plugins distributed outside this repository, typed in [`src/client/slot-contract.ts`](src/client/slot-contract.ts) and exported from `./client`. `settings.models.provider-card` (keyed) renders inside every card that shows a directory row — a saved row's card, its first-run setup posture, and the add-provider draft — dispatched with `entryKey = settingsNs` and owner props carrying the row's `ConfigurableProviderView`, its configured state, and its confirmed api-key credential state, so one registration under an adapter family's namespace receives every card of that family, hand-declared routes included; the hand-declared draft card has no directory row yet and dispatches nothing until saved. `settings.models.footer` (list) renders after the rows and the add controls. A registrant activates through `ctx.slots.inject` with a type-only import of this package's `/client` entry; without registrants both seats render nothing.

+The Models page includes **DeepSeek Account** (`deepseek-account`, **DeepSeek 账号** in Chinese). Its editor exposes the shared DeepSeek model catalog without API-key or base-URL inputs, and saves that catalog under the account route's own settings section (`llm-deepseek-account` by default), so an account edit never rewrites the `llm-deepseek` section the official route reads.

 - **Complete bytes** — PDF, HTML, common images, and spreadsheets call `remote.workspaceFiles.readBytes(sessionId, path, {}, signal)`. The binary Remote returns `data: Uint8Array<ArrayBuffer>` directly for `{ kind: 'bytes', data }`. The Host's `maxFileBytes` cap rejects oversized files rather than truncating them. PDF and spreadsheet renderers copy retained bytes before Worker transfer, keeping the Preview buffer usable. Bytes stay in transient view state, never persisted layouts or Session JSONL. Loading-mode changes retire previous results.
 - **Reload** — manual reload rereads only the current Preview tab through its Remote callbacks, preserving its scroll preference and retiring older requests. Automatic refresh uses the same callbacks after a `ResourceGroup` member changes. Each member's first metadata establishes a baseline without triggering reload or first-read version reconciliation; later changes received during a read remain pending for another refresh. Reads neither refresh shared metadata nor clear another tab's notice.
 
-When Developer tools is enabled, HTML fills the body edge to edge in a Blob iframe with exactly `sandbox="allow-scripts"`, without `allow-same-origin`; scripts cannot access the parent application's origin or file reader. The renderer loads directly declared relative `.js` classic scripts and `.css` stylesheets through its injected Remote callback, with fixed safety limits of 4 MiB per asset, 32 MiB total, and 64 distinct assets. Host code resolves the related path, and `readBytes` with `baseFile` returns native bytes. The dependency Resource is added after the read returns, using its `absolutePath` or a string `error.details.path` on failure; without a Host path, the Client does not guess one. Inside the renderer, base64 is used only to embed the iframe bootstrap payload in script text. A `<base href>` leaves dependency resolution to the browser, as do HTTPS resources. Local module imports, CSS `url()`/`@import`, and dynamic `fetch` do not use Host file access. Read failures, invalid UTF-8, or exceeded limits fail the preview rather than publishing a partial asset package. Replacing or unmounting the document releases its Blob URL.

 PNG, JPEG, GIF, WebP, BMP, ICO, and SVG render through Blob URLs in an `<img>` static-image context, rounded inside a 12px inset. Images default to fit width without enlarging content smaller than the pane; 100% uses the image's intrinsic CSS-pixel width. The shared zoom controls can produce horizontal and vertical scrolling, but do not provide drag-to-pan. Zoom changes retain the same `<img>` and Blob URL, so animated images continue playing. Raster formats can soften above their intrinsic size, while SVG remains on the browser's vector rendering path. SVG markup never enters the application DOM or an iframe, so its scripts cannot execute or reach the parent page. Replacing or unmounting the image revokes its Blob URL.

-`dsh-time-context` gives the model a clock: on eligible steps it appends a durable, source-attributed reading with the current time, the browser zone attached to the open request, and the elapsed time since the preceding model-visible message. It helps the model interpret otherwise-unqualified dates and times in the user's browser zone, and tells it to ask when current-turn browser zones are mixed or missing. The shipped Web bundle mounts it with Schedule. A positive `refreshIntervalMs` reduces how often readings accumulate; omission or `0` injects at every eligible step.

-description: Use when authoring, installing, configuring, or debugging persistent plugins and MCP connections in the current Harness profile, and for any visual object, decoration, or widget request that names no other destination, which means an installed UI plugin rendered in the Harness Web UI.
+description: Use when adding, enabling, disabling, installing, configuring, or debugging a plugin, bundle, feature, page, panel, tool, or MCP connection in the current Harness profile, including a shipped plugin that is disabled by default, and for any visual object, decoration, or widget request that names no other destination, which means an installed UI plugin rendered in the Harness Web UI.

 # Persistent Harness plugins
 
 Use ordinary workspace files to author a bundle, then `plugin_manager` with `action: install_bundle` and the absolute package directory as `target` to install it in the current profile. Changes affect every session in that profile and survive restart. Load `editing-cordis-compositions` for agent preset changes.
 
+Do not write the profile's `package.json` or `cordis.patch.yml`, create packages under `$DSH_HOME`, or run pnpm in the profile directory: `install_bundle` performs those steps, and each hand-made write outside the workspace needs its own approval. Every `plugin_manager` action, including `list_plugins` and `list_bundles`, also needs approval without Full access, so call it only when its result decides the next step.
+
+## Enable a shipped plugin
+
+A shipped bundle can resolve a plugin row and leave it `disabled`. The row id and its reason are in the shipped patch, `packages/bundle/*/cordis.patch.yml` in a source checkout. Write a workspace bundle whose patch overrides that row with `disabled: false` and inserts the Host rows it depends on; a source checkout's `apps/cli/config/examples/<feature>/cordis.yml` lists them for opt-in features. Packages shipped with dsh resolve from the dsh installation, so the bundle declares no dependencies on them. Install it with `install_bundle`.
+
 ## Deliver a working plugin first
 
 1. Resolve the requested result and destination. An unspecified visual destination is the current Harness Web UI; a standalone image or HTML file does not complete such a request. Choose reasonable visual details and implement a small first version; install it before visual refinement.
 2. Discover only the APIs needed for that version: `cordis_inspect_list`, then targeted `cordis_inspect_query` calls. For UI, query Client `Slots.listSubTree` and the selected slot's registration options and props. For anything beyond a static decoration, such as tool policy, agent context, session-derived state, or Chat rows, read `references/practices.md` before choosing the extension point. Once the chosen slot and registration API are known, write the plugin.
 3. Read the matching template under `templates/` with the file-read tool and write its copies into one workspace directory, or write the installable package, patch, and required Host/Client files there yourself. Check JavaScript syntax and the manifest, then install it. Before that first installation, do not create preview HTML, mock shells, design variants, screenshot scripts, or rasterizer tooling. Use the installed plugin itself as the first preview.
-4. Read the installation result. After `application: applied`, exercise the capability or inspect the live Client registration. Use the connected page for visual verification when browser control is available. For a page or panel, also verify design consistency: styles use only theme tokens, the plugin imports no Harness Client package such as `@deepseek-ai/dsh-client-ui-primitives`, the console shows no slot entry crash, and the view reads correctly in light and dark themes beside a comparable host page. State any verification limitation explicitly; installation and slot registration alone do not establish what the user can see.
+4. Read the installation result: its `application` and `warnings` fields decide whether the change is live, not server logs, terminal output, process lists, or the page's boot payload. Confirm new rows with `cordis_inspect_query`, which needs no approval, rather than paging `list_plugins`. After `application: applied`, exercise the capability or inspect the live Client registration. Use the connected page for visual verification when browser control is available. For a page or panel, also verify design consistency: styles use only theme tokens, the plugin imports no Harness Client package such as `@deepseek-ai/dsh-client-ui-primitives`, the console shows no slot entry crash, and the view reads correctly in light and dark themes beside a comparable host page. State any verification limitation explicitly; installation and slot registration alone do not establish what the user can see.
 5. Fix observed defects in the same plugin. When the requested result works, finish with its location and verification status. Do not continue speculative visual variants, optional features, or a new mock preview. Close any task list you created.

 ### Denied calls and escalation
 
-When a confined call is denied, the operation reports a denial marker naming the mode — `[sandbox: file access denied under <mode> mode]` — and, when the composition advertises escalation, an escalation hint. The model may retry the exact call once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a `justification`; the user sees one approval prompt and can allow once, reject, or cancel. A wider mode requires approval and applies to that one call only. Repeating the call's effective mode succeeds without approval; narrower targets remain invalid.

The model may retry the exact call once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a `justification`; the approval service obtains consent for the operation. The request retains its audit reason and supplies English and Chinese presentation copy with the model's justification unchanged. Missing translations follow the locale service's fallback chain, ultimately English; requesters own their translated presentation text. A wider mode requires approval and applies to that one call only. Repeating the call's effective mode succeeds without approval; narrower targets remain invalid.
