Client cordis boot and React-free object services: SlotsService wraps SlotCore and supplies renderer data sources; SessionsService owns Session objects, list/scope/history state; WorkspacesService depends on SessionsService and owns Workspace objects, list/actions, default-target derivation, and the New Session blank-reuse entry (`connectWorkspace`). The runtime fans the shared Host stream into both managers. Client sessions are always Host-born (Session+Agent+cwd in one `session.create`); the client holds no pre-entity session state — a session's Agent scope (the client mirror of host dsh-scope, keyed by the shared agent/session id) is born when its row enters the list mirror and dies with the prune. Contract: api-contracts v3 §4. `ConversationSnapshot` carries `todos` — the session's current todo projection: taken from the tail history page's full-log value (host-computed, independent of the page window), preserved across an older-page prepend, and overwritten by each live `todo/write` (last write wins). A tail response that omits the field means the log holds no `todo/write`, so the list resets to empty — a plan the log never kept (a write lost to a host crash) disappears on the next open or resync.

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 `todos`——会话当前的 todo 投影：取自尾页 history 携带的全量 log 值（host 计算，独立于分页窗口），跨往前翻页保留，并被每次实时 `todo/write` 覆盖（后写胜出）。尾页响应省略该字段即表示 log 中没有任何 `todo/write`，因此列表复位为空——log 从未留下的计划（写入因 host 崩溃丢失）会在下一次打开或 resync 时消失。

@@ -12,7 +12,7 @@ Generic tool rows classify the built-in bash, read, search, write, edit, and run
Tool rows are slots too — the standalone tool ring (`ToolViewRegistry`/`ctx.toolviews`/outlet) is retired. The chat entry declares the keyed `'conversation.chat.toolview'` hole (session scope; the key space is runtime-open); its render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`. The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openFile`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '<tool>', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar). Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders).
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 (`<done>/<total> 已完成 · <active item>` 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: -1` — above the queue rows — and is the durable plan strip: it selects `todos` off the session snapshot and renders `TodoPanel`, which takes the plain list, hides itself while the list is empty, and collapses to a header of title plus `"<done>/<total> tasks · <n> 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 persistent 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.
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 (`<done>/<total> 已完成 · <active item>` 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: -1` — above the queue rows — 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 collapses to a header of title plus `"<done>/<total> tasks · <n> 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.
Per-session UI state for selection and the active view lives in the declared chat store (`stores.ts` `createChatStore`); the InputHub owns the composer state machine and mirrors its draft into that store for persistence. Apply passes one store handle to the strict session subtree, chat view, and details registrations, so each session shares one instance and the framework owns its lifecycle. Components are pure: the framework standard kit supplies `useSession`/`sessionId`, global `useSessions`/`useWorkspaces`, and the input machine's `useInput`/`inputActions`; store faces and inject factories supply the remaining state and callbacks.

Theme plugin: ThemeService over the --dsw-* token base stylesheets (static scale + alias semantic layers). The service owns the theme preference (`light`/`dark`/`system`, persisted under `dsh.theme`), resolves `system` through `prefers-color-scheme`, and publishes immutable `ThemeSnapshot`s on the `theme/change` event; it never touches the DOM — ui-layout's presenter applies the resolved snapshot (`html { color-scheme }`, `body[data-ds-dark-theme]`, and inline alias tokens). Contract: api-contracts v3 §8.
`src/styles/` holds five sheets, all imported by the web shell's `base.css`: `base.css`, `design-platform.css`, `scrollbar.css`, `gradient-shadow-text.css`, and `shiki.css`. `scrollbar.css` is the sole consumer of the `--dsw-alias-scrollbar-*` tokens and must follow `design-platform.css`, which declares them.
Scrollbar rebinding contract: `scrollbar.css` binds `--dsh-scrollbar-thumb` and `--dsh-scrollbar-thumb-hover` on `body` to the l1 (base-surface) tokens, and both rendering paths read that pair. An elevated surface (menu, popover, dialog) sets `--dsh-scrollbar-thumb: var(--dsw-alias-scrollbar-bg-l2)` and `--dsh-scrollbar-thumb-hover: var(--dsw-alias-scrollbar-hover-l2)` on its own container; one rebind retints whichever path the engine took.
The two paths are mutually exclusive by construction. `scrollbar-width`/`scrollbar-color` sit inside `@supports not selector(::-webkit-scrollbar)` because a non-`auto` value of either makes Chromium and Safari discard every `::-webkit-scrollbar*` rule for that element, `::-webkit-scrollbar-thumb:hover` included — declaring both unconditionally leaves `--dsh-scrollbar-thumb-hover` with no rendering anywhere. Firefox therefore takes the standard properties and WebKit-based engines take the pseudo-elements, so the hover token only ever renders through the pseudo-element path. Reasoning and the measured computed values: [the scrollbar Agent Note](../../../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md).
## Model Experience
None, as the theme service manages a browser preference; nothing here reaches a model request.

主题插件：基于 --dsw-* token 基础样式表（静态尺度 + 别名语义层）的 ThemeService。该服务拥有主题偏好（`light`／`dark`／`system`，以 `dsh.theme` 为键持久化），将 `system` 通过 `prefers-color-scheme` 解析为实际主题，并发布不可变的 `ThemeSnapshot`，通过 `theme/change` 事件通知变化；它绝不接触 DOM：ui-layout 的呈现器会应用解析后的快照（`html { color-scheme }`、`body[data-ds-dark-theme]`，以及主题的别名 token 内联变量）。契约：api-contracts v3 §8。
`src/styles/` 下有五张样式表，全部由 web 壳的 `base.css` 导入：`base.css`、`design-platform.css`、`scrollbar.css`、`gradient-shadow-text.css` 与 `shiki.css`。`scrollbar.css` 是 `--dsw-alias-scrollbar-*` token 的唯一消费方，必须排在声明这些 token 的 `design-platform.css` 之后。
滚动条重新绑定契约：`scrollbar.css` 在 `body` 上把 `--dsh-scrollbar-thumb` 与 `--dsh-scrollbar-thumb-hover` 绑定到 l1（基础表面）token，两条渲染路径都读取这一组变量。抬升表面（菜单、浮层、对话框）在自己的容器上设置 `--dsh-scrollbar-thumb: var(--dsw-alias-scrollbar-bg-l2)` 与 `--dsh-scrollbar-thumb-hover: var(--dsw-alias-scrollbar-hover-l2)`；一次重新绑定即可为引擎实际走的那条路径换色。
两条路径在构造上互斥。`scrollbar-width`／`scrollbar-color` 写在 `@supports not selector(::-webkit-scrollbar)` 之内，因为这两个属性只要取非 `auto` 值，Chromium 与 Safari 就会丢弃该元素上的全部 `::-webkit-scrollbar*` 规则，`::-webkit-scrollbar-thumb:hover` 也在其中——若无条件地同时声明，`--dsh-scrollbar-thumb-hover` 在任何引擎上都不会被渲染。因此 Firefox 走标准属性，WebKit 系引擎走伪元素，hover token 只经由伪元素这条路径渲染。推理过程与实测计算值见[滚动条 Agent Note](../../../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md)。

because the engines that implement the hover pseudo-element are exactly the
ones the standard properties silence, and Firefox has no hover
pseudo-element to fall back on.
`not selector(::-webkit-scrollbar)` is true only where the pseudo-element
is unimplemented, so Firefox takes the standard path and WebKit-based

## Public API
- `listCandidates(agent, query?, limit?)` lists sessions other than `agent.id`, filters case-insensitively by id, cwd, or the latest log-backed title, and ranks same-cwd, cwd-less, then other-cwd records while preserving `listSessions()` creation order within each group. Each selected candidate uses that title as the mention label and falls back to the session id when the title is absent or unreadable; message bodies are not searched.
- `prepare(agent, content, references, signal?)` preserves first-mention order, deduplicates ids, rejects self-reference and more than the configured distinct-source limit, reads every source in parallel, and returns detached content plus zero or one aggregated `UserMessageData` context. Any invalid reference, failed read, cancellation, or budget failure rejects before the host calls `followup()` or `steer()`.
- `prepare(agent, content, references, signal?)` preserves first-mention order, deduplicates ids, rejects self-reference and more than the configured distinct-source limit, reads every source in parallel, and returns detached content plus zero or one aggregated, identified `UserMessage` context. Any invalid reference, failed read, cancellation, or budget failure rejects before the host calls `followup()` or `steer()`.
- `encodeSessionReferenceUri()` and `decodeSessionReferenceUri()` implement `dsh-session:<base64url(JSON.stringify(sessionId))>` so every JavaScript string id round-trips exactly. `formatSessionReferenceMention()` emits `@[label](uri)`, and `parseSessionReferenceText()` replaces Markdown mentions or bare canonical URIs with readable `@label` text while returning structured references. Explicit Markdown mentions reject every malformed URI; bare text is considered a reference only when a non-empty base64url-shaped payload follows the scheme, and a matching noncanonical candidate still fails. Empty or punctuation-only scheme mentions remain ordinary discussion text.

## 公开 API
- `listCandidates(agent, query?, limit?)` 会列出 `agent.id` 之外的会话，按 id、cwd 或日志中最新的标题进行不区分大小写的筛选，再按同 cwd、无 cwd、其他 cwd 记录排序，同时保持每组内的 `listSessions()` 创建顺序。每个已选候选会话都使用该标题作为 mention label；标题不存在或无法读取时回退到会话 id。不搜索消息主体。
- `prepare(agent, content, references, signal?)` 会保留首次 mention 顺序、对 id 去重，并拒绝自引用或超过已配置不同源上限的情况。它会并行读取所有源，返回与输入脱离的内容，外加零个或一个聚合 `UserMessageData` 上下文。任何无效引用、读取失败、取消或预算失败都会在宿主调用 `followup()` 或 `steer()` 之前被拒绝。
- `prepare(agent, content, references, signal?)` 会保留首次 mention 顺序、对 id 去重，并拒绝自引用或超过已配置不同源上限的情况。它会并行读取所有源，返回与输入脱离的内容，外加零个或一个聚合且带标识的 `UserMessage` 上下文。任何无效引用、读取失败、取消或预算失败都会在宿主调用 `followup()` 或 `steer()` 之前被拒绝。
- `encodeSessionReferenceUri()` 与 `decodeSessionReferenceUri()` 实现 `dsh-session:<base64url(JSON.stringify(sessionId))>`，因此每个 JavaScript 字符串 id 都能精确往返。`formatSessionReferenceMention()` 发出 `@[label](uri)`，`parseSessionReferenceText()` 将 Markdown mention 或裸规范 URI 替换为可读的 `@label` 文本，并返回结构化引用。显式 Markdown mention 会拒绝每个格式错误的 URI；只当 scheme 后跟非空、符合 base64url 形状的 payload 时，裸文本才被视为引用，匹配但非规范的候选项仍会失败。空 scheme mention 或只含标点符号的 scheme mention 仍是普通讨论文本。

Configured agents start automatically. A model call requires both `provider` and `model`; `agent/request` may supply a missing pair before dispatch. `maxParallelToolCalls` bounds every agent's rolling pool for parallel-safe calls and defaults to `10`. `cwd` applies only to fresh sessions, while `resumeSessionId` retains persisted metadata. Configured agents use the deployment persona, and programmatic setup can shadow it per agent. This plugin supplies the per-agent `provider`, `model`, and `cwd` prompt variables; harness identity and deployment persona belong to `dsh-system-prompt`.
Configured agents start automatically. A model call requires both `provider` and `model`; `agent/request` may supply a missing pair before dispatch. An optional positive `maxTokens` seeds each conversation request's output cap and is logged in its request header. `maxParallelToolCalls` bounds every agent's rolling pool for parallel-safe calls and defaults to `10`. `cwd` applies only to fresh sessions, while `resumeSessionId` retains persisted metadata.

### Internal concrete driver
The concrete `ReactLoopAgent`, its queued input, outbox, and run controls are package-internal. The package root exports only the plugin/service/config contract, and the package exports map exposes no `./src/*` escape hatch; lifecycle owners create agents through `ctx.agents` rather than naming, constructing, or starting driver internals. One prepared session can be claimed by only one concrete driver, and everything observable happens through session events and the `agent/*` event taxonomy.
The unified `send()` primitive routes content and source by (`target` × `wakeup`); `followup`/`steer`/`inject` are its fixed-preset aliases. A `next-turn` item joins the queued FIFO, waking the driver unless `wakeup: false`; admission happens before any turn opens. The loop opens a private next-step acceptance window before `agent/prompt-submit` and closes it before `turn/end`. During that window, `steer()` and `inject()` stage in one outbox; an allowed admission opens the turn, records the prompt and returned `additionalContexts`, then drains the staged input before the first request. A blocked or failed admission writes no prompt or hook-produced context. A caller-staged context-only batch then takes idle injection's immediate append, while steering and context staged beside it remain pending for retry or a later admitted prompt. Outside the window, steering becomes a waking queued prompt and injection immediately appends `user/message` without opening a turn or running the model. Every inbox enqueue publishes `agent/inbox/enqueue` with the resolved queued-or-steering placement; taking it publishes `agent/inbox/dequeue`, and `cancel()` without `keepInbox` publishes `agent/inbox/discard`.

### 包内部实体驱动器
实体 `ReactLoopAgent`、其排队输入、outbox 与运行控制均为包内部实现。包根只导出插件／服务／配置契约，包导出映射不提供 `./src/*` 逃逸路径；生命周期拥有方通过 `ctx.agents` 创建 agent，而不是点名、构造或启动驱动器内部组件。一个准备完成的会话只能由一个实体驱动器认领；所有可观测行为都通过会话事件和 `agent/*` 事件分类体系发生。
统一的 `send()` 原语按（`target` × `wakeup`）路由内容与来源；`followup`/`steer`/`inject` 是它的固定预设别名。`next-turn` 项加入排队 FIFO，除非 `wakeup: false`，否则会唤醒驱动器；接纳发生在任何轮次开启之前。循环在 `agent/prompt-submit` 之前打开一个私有的 next-step 接收窗口，并在 `turn/end` 之前关闭它。在该窗口内，`steer()` 与 `inject()` 会暂存到同一个 outbox；接纳获准后会开启轮次，记录提示词及其返回的 `additionalContexts`，再于首次请求前排空暂存输入。接纳被阻止或失败时，不会写入提示词或钩子生成的上下文。之后，仅含调用方暂存上下文的批次会采用空闲注入的立即追加行为，而 steering（中途引导）及与其一同暂存的上下文则继续待处理，以供重试或之后获准的提示词使用。窗口之外，steering 会成为唤醒驱动器的排队提示词，而注入会立即追加 `user/message`，不开启轮次也不运行模型。每次 inbox 入队都会发布 `agent/inbox/enqueue`，并携带解析出的 queued 或 steering 路由归类；取走它会发布 `agent/inbox/dequeue`；`cancel()` 在不带 `keepInbox` 时会发布 `agent/inbox/discard`。

The scoped-registration surface: `Agent.ctx` is the agent's scope context (`dsh-scope`, key = the agent) — register tools/sections/variables/listeners through it for that agent alone, all unwound on disposal. `agentEvents(ctx, agent)` is the fused dispatcher for ordinary agent-subject operations (carrier + injected subject in one move); its notification mode invokes every listener and contains both synchronous throws and returned-promise rejections. The registry lifecycle pair reuses one stable routing carrier. `assembleContextFor(agent)` builds the per-agent assembly context (`agent` + `scope` together). `installAgentLlmTarget(agentCtx, target)` snapshots a mutable provider/model/reasoning-effort selection during prompt assembly, applies the route to prompt variables, and applies the complete target to request routing for one step; an absent selected effort clears an inherited effort so the target uses adapter/provider defaults. `CreateAgentOptions.setup(agentCtx)` and `ResumeAgentOptions.setup(agentCtx)` compose a fresh or resumed agent's scoped world while both objects remain unpublished. Setup is trusted, composition-only same-process code: drive the agent only after creation resolves.
`AgentOptions` supplies the initial provider/model route and an optional positive `maxTokens` output cap. The concrete loop records the cap in the request header and applies it to each conversation-model request; callers that omit it leave provider defaults in control.
- `ctx.agents.register(agent: Agent): () => void` — record an **already-constructed** agent. Disposed with the calling fiber.
- Advanced ordered lifecycle: `enter(agent, owner): () => void` enforces `agent.id === agent.session.id`, performs the authoritative ID collision check, and inserts without announcing; `owner` explicitly records the live creator-agent relation (or `undefined` for a root), independently of durable session lineage. `announce(agent)` emits `agent/created` exactly once. A detach requested synchronously by a creation listener is deferred until that dispatch unwinds, and every detach checks the captured entry object, so a stale capability cannot delete a later same-ID replacement. The async factory uses this split; ordinary plugins use `register()`.

Most interception points are cooperative waterfalls. Turn-scoped asynchronous seams receive one explicit `AbortSignal`, with `signal` immediately before a waterfall's final `next`; listeners may cooperate but must not retain it as authority over another turn. `agent/step` is the serial checkpoint before request derivation, while `agent/request-error` is the failed-model-request recovery waterfall: it receives the exact error, normalized failure facts, and signal after the failed step closes. A listener returns `{ kind: 'retry' }` without calling `next()` when it owns recovery; the loop closes the failed turn and opens one numbered retry turn. `agent/turn-stopping` runs before an otherwise completed turn closes. Ordinary queued prompts remain intact. Effective broad cancellation first emits the observe-only `agent/cancel-requested` with its resolved typed cause, then clears queues and aborts; notification failures are contained and cannot veto the stop. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) owns signal lifetime; the [agent-scope runtime-design Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.md#three-execution-boundaries-are-deliberately-one-way) owns scoped dispatch and terminal settlement.
`PromptDecision.additionalContexts` is an array so every context keeps its own source. Allowed prompt content and every additional context become separate model-facing `user/message` events before the turn runs. A listener that wraps a downstream allow preserves its `content` and `additionalContexts` unless it intentionally replaces either field; the returned allow is authoritative.
`PromptDecision.additionalContexts` is an array of identified, frozen `UserMessage` values so every context keeps its own identity and source. The admitted prompt and every additional context become separate model-facing `user/message` events before the turn runs. A listener that wraps a downstream allow preserves its `content` and `additionalContexts` unless it intentionally replaces either field; replacing admitted content preserves the prompt's identity.
Turn and step boundaries and the model token stream are durable `session/event` facts rather than mirrored `agent/*` notifications.

The handle every plugin programs against:
- `agent.send(input, options)` — the one delivery primitive over the (`target` × `wakeup`) matrix. `input` is the existing `UserMessageData { content, source }`, while `SendOptions` requires only the routing policy `target` and `wakeup`. The agent snapshots and freezes `input` before publication or queueing, so later caller or observer mutation cannot change the accepted message. It returns the accepted message's opaque `AgentMessageId`, which the message's `agent/inbox/enqueue`/`dequeue`/`discard` events carry so a caller can correlate a queued item with its lifecycle; enqueue also carries the resolved `queued | steering` placement so listeners never reconstruct acceptance-time routing from later state. `target: 'next-turn'` queues one independent FIFO item that, if admitted, becomes the sole ordinary prompt in its turn. `target: 'next-step'` with `wakeup: true` submits steering, while `target: 'next-step'` with `wakeup: false` injects durable context without running the model.

- `agent.send(message, options)` — the one delivery primitive over the (`target` × `wakeup`) matrix. `message` is an already identified, frozen `UserMessage`; callers normally create it with `createUserMessage()` before routing begins. `SendOptions` owns only the `target` and `wakeup` policy. The agent publishes or queues the complete value as-is without minting or replacing its identity. The message's `agent/inbox/enqueue`/`dequeue`/`discard` events carry it so callers can correlate a queued item with its lifecycle; enqueue and dequeue also carry the resolved `queued | steering` placement so repeated message identities retire from the correct FIFO. `target: 'next-turn'` queues one independent FIFO item that, if admitted, becomes the sole ordinary prompt in its turn. `target: 'next-step'` with `wakeup: true` submits steering, while `target: 'next-step'` with `wakeup: false` injects durable context without running the model.

- `agent.steer(input)` — the `next-step`/wakeup preset: during prompt admission or an open turn, stage steering for the next safe boundary without dispatching `agent/prompt-submit`; outside that acceptance window, delegate to a woken follow-up. Admission failure leaves staged steering for retry or a later admitted prompt, while cancellation or disposal may discard it.
- `agent.inject(input)` — the `next-step`/no-wakeup preset: append model-facing context without running the model; the next request sees a verbatim user-role message whose provenance is carried by the required `input.source`. During prompt admission or an open turn, injection waits in the outbox for the next safe boundary. Outside that acceptance window, it appends immediately without opening a turn; a context-only admission batch takes this fallback if admission closes without a turn, while context staged beside steering remains pending with it. Persistence reacts to `session/event` independently. Injection emits no `agent/inbox/*` event.
