## Decision
|
||||
|
||||
**One primitive, three preset aliases.** The `Agent` interface's `send(input, { target, wakeup })` covers the (`target` × `wakeup`) matrix. Its `UserMessageData` input owns the inseparable model-facing `content` and producer `source`; the complete `SendOptions` owns only routing policy. `followup` (`next-turn`/wakeup), `steer` (`next-step`/wakeup), and `inject` (`next-step`/no-wakeup) each accept that one input and fix the policy. `wakeup` means "make the model run": wake a parked driver for a `next-turn` item, or force a continuation for a running `next-step` item. `next-turn`/no-wakeup (queue without waking) is representable with no alias and no current caller.

||||
**One primitive, three preset aliases.** The `Agent` interface's `send(message, { target, wakeup })` covers the (`target` × `wakeup`) matrix. Its complete `UserMessage` owns identity, role, model-facing `content`, and producer `source`; the complete `SendOptions` owns only routing policy. `followup` (`next-turn`/wakeup), `steer` (`next-step`/wakeup), and `inject` (`next-step`/no-wakeup) each accept that one message and fix the policy. `wakeup` means "make the model run": wake a parked driver for a `next-turn` item, or force a continuation for a running `next-step` item. `next-turn`/no-wakeup (queue without waking) is representable with no alias and no current caller.
|
||||
|
||||
**inject keeps its mechanism.** The `next-step`/no-wakeup path is exactly the old `inject`: durable model-facing context appended at the current log position, deferred while prompt admission or a turn owns the next safe boundary, and appended directly outside that window. It bypasses the FIFOs entirely, while its required `UserMessageData.source` preserves the caller's explicit provenance.

It bypasses the FIFOs entirely, while its required `UserMessage.source` preserves the caller's explicit provenance.
|
||||
|
||||
**context/message is gone.** Injected context is now a `user/message`; context producers supply the appropriate non-user `source` explicitly, and typed source variants carry any domain-specific durable provenance. The surface, derivation, and `SurfaceEventType` drop `context/message`; consumers that need "is this a human prompt?" read `source.kind === 'user'` instead of the event type.
|
||||
|
||||
**Goal replay disambiguates by round, not type.** A goal state change is a round-zero goal-sourced `user/message` whose source carries the complete change; a positive round is an admitted continuation prompt. `decodeGoalEvent` takes a `user/message` and fails loud when goal-state content and its typed source disagree.
|
||||
|
||||
**`send` returns an id.** `send` (and the aliases) return an opaque branded `AgentMessageId` for the accepted message; `send`'s previous return was `void`.
|
||||
**`send` does not return identity.** Callers already own the complete message and its opaque `MessageId`; creation and freezing are owned by the [identified immutable message decision](2026-07-28-identified-immutable-message-values.md), not by routing.
|
||||
|
||||
**Three inbox events replace agent/queued.** `agent/inbox/enqueue` (an item entered a FIFO), `agent/inbox/dequeue` (the driver claimed one), and `agent/inbox/discard` (`cancel()` dropped pending items) type their `AgentMessage` payload with only the accepted message's returned `id`, content, and source. Enqueue separately carries the resolved `queued | steering` placement captured by the producer at acceptance time, so observers and reconnect mirrors never reconstruct routing from later status or session history. Injection never touches a FIFO and emits none of these. Every FIFO entry publishes an enqueue, including steering submitted by an `agent/turn-stopping` listener, so the ledger stays balanced with its later dequeue or discard. The `dsh-agent` invariant companion asserts FIFO conservation: a per-agent outstanding count that dequeue and discard can never drive negative.

||||
**Three inbox events replace agent/queued.** `agent/inbox/enqueue` (an item entered a FIFO), `agent/inbox/dequeue` (the driver claimed one), and `agent/inbox/discard` (`cancel()` dropped pending items) carry the accepted `UserMessage`. Enqueue and dequeue also carry the resolved `queued | steering` placement captured at acceptance, so observers and reconnect mirrors retire repeated message identities from the correct FIFO without reconstructing routing from later status or session history. Injection never touches a FIFO and emits none of these. Every FIFO entry publishes an enqueue, including steering submitted by an `agent/turn-stopping` listener, so the ledger stays balanced with its later dequeue or discard. The `dsh-agent` invariant companion asserts FIFO conservation: a per-agent outstanding count that dequeue and discard can never drive negative.
|
||||
|
||||
**Admission accepts next-step input without becoming a turn.** The loop opens a private next-step acceptance window before `agent/prompt-submit`, keeps it open through the turn, and closes it before `turn/end`. Steering and injection received during admission therefore remain together in the outbox and join an allowed turn. If admission blocks or fails, a context-only caller batch takes idle injection's immediate append, while steering and context staged beside it remain available to retry; neither path writes the rejected prompt. When a later prompt is admitted, retained outbox input enters its turn before that prompt, while input accepted during the current admission remains after the prompt. Closing the window before `turn/end` preserves the rule that reentrant late steering becomes an independent queued turn. `Agent.acceptsNextStep` exposes whether a `next-step` send would currently join this window; `status` remains the broader activity signal rather than a routing predicate.
|
||||
|
||||
**One accepted message keeps one representation.** Durable user-role input and additional model-facing context both use `UserMessageData { content, source }` directly; public `AgentMessage` extends it with the correlation `id`, and the loop-private `PendingMessage` extends that with `wakeup`. The loop clones and freezes `UserMessageData` before publication, queueing, or immediate append, so later caller or observer mutation cannot change the accepted value. A queued message that becomes steering enters the outbox as the same `PendingMessage` object, while injected and tool-produced context enters as plain `UserMessageData`. The outbox therefore stores their union directly instead of wrapping steering beside a duplicate copy of its content and source. Provider-native assistant messages remain adapter-owned output types and do not participate in this input hierarchy.
|
||||
**One accepted message keeps one representation.** Durable user-role input and additional model-facing context both use the identified, frozen `UserMessage` directly. The loop stores that value beside private routing state rather than copying its identity, content, or source into another public shape. A queued message that becomes steering keeps the same message value in the outbox, while injected and tool-produced context each carry their own identified message. The [identified immutable message decision](2026-07-28-identified-immutable-message-values.md) supersedes this note's former `UserMessageData`/`AgentMessage` hierarchy and extends the representation to assistant and tool-result messages.
|
||||
|
||||
**Idle wakeup follows acceptance.** Before publishing enqueue, a waking queued send installs quiescence ownership and schedules driver admission for a microtask that runs after the id returns. Every send in one synchronous caller stack therefore resolves placement against the same pre-admission state, while reentrant cancellation or teardown cannot retire before the scheduled admission settles. Two idle `steer()` calls remain two FIFO turns instead of the first opening an admission window that captures the second.

|
||||

||||
**goal 回放靠轮次而非类型来区分。** 一次 goal 状态变更是一条第 0 轮、来源为 goal 的 `user/message`，其 source 携带完整变更；正数轮次则是一条已准入的继续执行提示词。`decodeGoalEvent` 接收一条 `user/message`，并在 goal 状态内容与其类型化 source 不一致时立即报错。
|
||||
|
||||
**`send` 返回一个 id。** `send`（以及其别名）为被接受的消息返回一个不透明的 branded `AgentMessageId`；`send` 此前的返回值是 `void`。

**`send` 不返回标识。** 调用方已经持有完整消息及其不透明的 `MessageId`；消息的创建与冻结由[带标识的不可变消息值决策](2026-07-28-identified-immutable-message-values.md)负责，而不是由路由负责。

**三个 inbox 事件取代 agent/queued。** `agent/inbox/enqueue`（一个队列项进入某个 FIFO）、`agent/inbox/dequeue`（驱动器认领了一个）和 `agent/inbox/discard`（`cancel()` 丢弃了待处理项）都将各自的 `AgentMessage` 载荷类型限定为仅包含被接受消息所返回的 `id`、内容和来源。enqueue 还会单独携带生产方在接受消息时捕获的已解析 `queued | steering` 放置方式，因此观察方和重连镜像永远不必根据后续状态或会话历史重建路由。注入从不触及 FIFO，也不发出这些事件中的任何一个。每一次 FIFO 入队都会发布一个 enqueue 事件，包括 `agent/turn-stopping` 监听器提交的 steering，因此账目会与其后的 dequeue 或 discard 保持平衡。`dsh-agent` 的不变量配套断言 FIFO 守恒：一个按 agent 计的未结算计数，dequeue 和 discard 永远无法把它压到负数。

**准入接受 next-step 输入，但不会因此成为一个轮次。** 循环会在 `agent/prompt-submit` 前打开一个私有的 next-step 接受窗口，使其贯穿整个轮次，并在 `turn/end` 前关闭。因此，在准入期间收到的 steering 和注入会一起留在 outbox 中并加入获准轮次。如果准入被阻止或失败，仅含调用方上下文的批次会采用空闲注入的立即追加行为，而 steering 及与其一同暂存的上下文仍可重试；两种路径都不会写入被拒绝的提示词。后续提示词获准时，保留在 outbox 中的输入会先于该提示词进入其轮次，而当前准入期间接受的输入则留在提示词之后。在 `turn/end` 前关闭窗口，可以保留这样的规则：可重入的晚到 steering 会成为一个独立的排队轮次。`Agent.acceptsNextStep` 会公开一次 `next-step` 发送当前是否会加入该窗口；`status` 仍是更宽泛的活动信号，而非路由判据。
|
||||
|
||||
**一条已接受消息只保留一种表示。** 持久的用户角色输入和附加的模型可见上下文都直接使用 `UserMessageData { content, source }`；公开的 `AgentMessage` 在此基础上增加用于关联的 `id`，循环私有的 `PendingMessage` 再增加 `wakeup`。循环会在发布、入队或立即追加前克隆并冻结 `UserMessageData`，因此调用方或观察方后续的修改无法改变已接受的值。一条成为 steering 的排队消息会以同一个 `PendingMessage` 对象进入 outbox，而注入和工具产生的上下文则以普通 `UserMessageData` 进入。因此，outbox 直接存储这两种类型的联合，而不再把 steering 与一份重复的内容和来源副本包装在一起。提供方原生的助手消息仍是适配器拥有的输出类型，不参与这套输入层级。
|
||||
**一条已接受消息只保留一种表示。** 持久的用户角色输入和附加的模型可见上下文都直接使用带标识且冻结的 `UserMessage`。循环把该值与私有路由状态存放在一起，不会将其标识、内容或来源复制到另一种公开形状中。一条成为 steering 的排队消息会在 outbox 中保留同一个消息值，而注入和工具产生的上下文则各自携带带标识的消息。[带标识的不可变消息值决策](2026-07-28-identified-immutable-message-values.md)取代了本记录此前的 `UserMessageData`/`AgentMessage` 层级，并将这一表示扩展到 assistant 消息和工具结果消息。
|
||||
|
||||
**空闲唤醒在接受之后发生。** 在发布 enqueue 前，一次会唤醒驱动器的排队发送会先取得完全停稳所有权，并把驱动器准入调度到一个会在该次发送返回 id 后运行的微任务中。因此，同一同步调用栈中的每次发送都会基于同一份准入前状态解析放置方式，而可重入的取消或拆除在已调度的准入结算前无法完成退役。空闲时的两次 `steer()` 调用会保留为两个 FIFO 轮次，而不会因第一次调用打开准入窗口而把第二次吸纳进去。

Tool-produced additional contexts enter the outbox after the corresponding tool results.

# Agent Note: One carrier-level browser-trust boundary for the whole /api surface
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-28-api-browser-trust-boundary.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The web GUI host serves `/api` over plain HTTP (default `127.0.0.1:3080`, `--host 0.0.0.0` supported), and the surface includes remote-code-execution-grade methods — `session.prompt` drives an agent that runs bash. A browser turns the operator into a confused deputy against such a local API in two classic ways: a malicious page fires a "simple" cross-site POST (`text/plain` — sent without a CORS preflight) whose side effects execute even though the response stays unreadable, and a DNS-rebound origin talks to the socket as if same-origin, making CORS inapplicable entirely, with only the `Host` header betraying the attacker's domain. Before this decision the system's only browser-trust check (`isTrustedNativeDialogRequest`: loopback socket + same-origin + loopback Host) guarded exactly one cosmetic route — `host.pickDirectory`, whose native dialog pops on the host's screen — while every consequential method was unguarded. Guarding per-RPC also could not survive the upcoming in-app directory browser, whose whole point is serving legitimately remote clients that a loopback rule would refuse.
|
||||
|
||||
## Decision
|
||||
|
||||
Enforce browser trust once, at the carrier, for the entire `/api` prefix — two halves in two stacked PRs:
|
||||
|
||||
- **Media-type fence (dsh-host-apiproxy)**: every `/api` POST must declare `application/json`, else 415 before parsing. Cross-site "simple" requests thereby stop existing: any cross-site attempt is forced into a CORS preflight this server never answers.
|
||||
- **Authority fence (dsh-client-connection, `src/api-request-trust.ts`)**: every request must present a `Host` that is loopback or matches a `trustedHosts` entry (exact on `host:port`, any port on port-less entries, WHATWG-normalized; rebinding defense). Deliberately no shortcut for unmarked requests: over plain HTTP a browser attaches neither `Origin` nor Fetch-Metadata to reads (EventSource, images, navigations — those headers go only to trustworthy destinations), so an unmarked request may be a rebound browser read whose response the page can read, and Host is the one header rebinding cannot forge; non-browser clients pass via loopback, the derived LAN IP literals, or a declared authority. An attached `Origin` must equal the Host authority; `sec-fetch-site: cross-site` is refused outright. A `trustedHosts` entry that is not a bare, canonical authority fails the plugin load — WHATWG parsing would otherwise quietly authorize the hostname inside a typo or broaden an exact-port grant. `host.pickDirectory` loses its bespoke guard and rides the same fence.
|
||||
|
||||
Two boundaries stay deliberately out of scope: reachability is the webserver binding's policy (`host: 127.0.0.1 | 0.0.0.0`), and authentication for genuinely remote deployments is deferred work recorded in the connection README — the fence is a confused-deputy defense, not an auth layer. The old guard's loopback-socket check was dropped rather than generalized: with binding expressing reachability and `trustedHosts` naming remote authorities, the socket address adds nothing a header fence does not already cover.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
- **Per-RPC guards (status quo extended).** Rejected: the guard list trails the method list forever, the highest-value methods were already unguarded, and a loopback rule on browse RPCs would break the remote deployments they exist for.
|
||||
- **CORS headers + credential omission.** Rejected: we never want cross-origin reads at all, so answering preflights only widens the surface; refusing them is strictly stronger and simpler.
|
||||
- **Auth tokens now.** Rejected for this change: token minting/storage/rotation is real product surface; the fence closes the browser-deputy holes today without pre-deciding the auth design.
|
||||
|
||||
## Consequences
|
||||
|
||||
- Any future `/api` method is covered by construction; there is no per-route trust decision left to forget.
|
||||
- Non-loopback deployments must have their serving authorities trusted or requests are refused. The dsh CLI keeps its advertised `--host 0.0.0.0` LAN URL working by deriving the machine's LAN IP literals into the connection row (port-less entries — an IP-literal Host cannot be a rebound name, and the bound port may be OS-assigned) and offers `dsh web --trusted-host` for named authorities; compositions the CLI does not boot declare `trustedHosts` themselves. Non-browser automation rides the same fence: loopback, a derived LAN IP, or a declared authority passes; an undeclared DNS alias is refused.
|
||||
- Clients must label POST bodies `application/json` (ours always did; raw-fetch tests gained the header).
|
||||
- The trusted-network assumption of an unauthenticated `0.0.0.0` deployment is now documented instead of implicit.

# Agent Note：整个 /api 面共用一道载体级浏览器信任边界
|
||||
|
||||
状态：已实现
|
||||
|
||||
[English](2026-07-28-api-browser-trust-boundary.md) | 中文
|
||||
|
||||
## 问题
|
||||
|
||||
Web GUI 宿主以纯 HTTP 提供 `/api`（默认 `127.0.0.1:3080`，支持 `--host 0.0.0.0`），而这个面上有远程代码执行级别的方法——`session.prompt` 驱动的 agent 可以运行 bash。浏览器会用两种经典方式把操作者变成攻击此类本地 API 的"混淆代理人"：恶意页面发出跨站"简单请求" POST（`text/plain`——不经 CORS 预检即发出），其副作用照常执行、只是响应不可读；以及 DNS rebinding 后的源以"同源"身份直连 socket，CORS 整体失效，只有 `Host` 头会暴露攻击者的域名。在本决策之前，系统里唯一的浏览器信任检查（`isTrustedNativeDialogRequest`：回环 socket + 同源 + 回环 Host）只守着一个装饰性的路由——`host.pickDirectory`，其原生对话框弹在宿主屏幕上——而所有真正要命的方法都在裸奔。按 RPC 逐个设防也活不过即将到来的应用内目录浏览器：它存在的意义就是服务合法的远程客户端，回环规则恰恰会拒绝它们。
|
||||
|
||||
## 决策
|
||||
|
||||
在载体层对整个 `/api` 前缀一次性执行浏览器信任检查——两半各占一个栈式 PR：
|
||||
|
||||
- **媒体类型栅栏（dsh-host-apiproxy）**：每个 `/api` POST 必须声明 `application/json`，否则在解析前以 415 拒绝。跨站"简单请求"由此不复存在：任何跨站尝试都被逼进一次本服务器从不应答的 CORS 预检。
|
||||
- **权威栅栏（dsh-client-connection，`src/api-request-trust.ts`）**：每个请求的 `Host` 都必须是回环地址，或与某个 `trustedHosts` 条目匹配（带端口的 `host:port` 条目精确匹配，不带端口的条目匹配任意端口，均经 WHATWG 归一化；rebinding 防御）。刻意不为无标记请求开捷径：明文 HTTP 下浏览器的读取（EventSource、图片、导航——这些头只发给可信目标）既不带 `Origin` 也不带 Fetch-Metadata，因此无标记请求可能是被重绑页面发起且响应可被读走的读取，而 Host 是重绑唯一伪造不了的请求头；非浏览器客户端经由回环地址、推导的 LAN IP 字面量或已声明的权威通过。若带 `Origin` 则必须与 Host 权威完全一致；`sec-fetch-site: cross-site` 一律拒绝。不是纯的、规范形权威的 `trustedHosts` 条目会让插件加载失败——否则 WHATWG 解析会悄悄授权笔误里的 hostname，或放大精确端口授权。`host.pickDirectory` 失去专属守卫，与其他请求同栅而行。
|
||||
|
||||
两条边界刻意留在范围之外：可达性归 webserver 绑定配置（`host: 127.0.0.1 | 0.0.0.0`）管辖；真正远程部署的认证是延期工作，记录在 connection README——这道栅栏是混淆代理人防御，不是认证层。旧守卫的回环 socket 检查被放弃而非泛化：绑定表达可达性、`trustedHosts` 点名远程权威之后，socket 地址提供不了头部栅栏覆盖不到的任何东西。
|
||||
|
||||
## 曾考虑的替代方案
|
||||
|
||||
- **按 RPC 设防（延续现状）。** 否决：守卫清单永远追着方法清单跑，价值最高的方法本来就没被守住，而 browse RPC 上的回环规则会破坏它们为之存在的远程部署。
|
||||
- **CORS 头 + 省略凭据。** 否决：我们根本不想要任何跨源读取，应答预检只会扩大暴露面；拒绝预检严格更强也更简单。
|
||||
- **现在就上认证令牌。** 在本变更中否决：令牌的签发/存储/轮换是真实的产品面；栅栏今天就能封死浏览器代理人漏洞，无需预先决定认证设计。
|
||||
|
||||
## 后果
|
||||
|
||||
- 未来任何 `/api` 方法天然在覆盖范围内；不存在会被遗忘的按路由信任决定。
|
||||
- 非回环部署的服务权威必须获得信任，否则请求会被拒绝。dsh CLI 通过把本机 LAN IP 字面量推导进 connection 行（不带端口的条目——IP 字面量 Host 不可能是被重绑的域名，且绑定端口可能由操作系统分配）来保住它广告出的 `--host 0.0.0.0` LAN URL，并提供 `dsh web --trusted-host` 声明具名权威；CLI 不参与引导的组合自行声明 `trustedHosts`。非浏览器自动化走同一道栅栏：回环地址、推导的 LAN IP 或已声明的权威可通过；未声明的 DNS 别名会被拒绝。
|
||||
- 客户端必须给 POST 体标注 `application/json`（我们自己的客户端一向如此；裸 fetch 测试补上了该头）。
|
||||
- 无认证 `0.0.0.0` 部署的"信任网络"假设从隐含变为成文。

# Agent Note: Consolidated TUI presentation and navigation
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-28-consolidated-tui-presentation.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The terminal UI accumulated independent presentation rules that interacted poorly: palette roles aliased one another or inverted emphasis on light terminals; tool-card framing, output, and exit markers repeated or competed; injected context was parsed as XML and could not fold reliably; and `/resume` excluded sessions outside the current workspace even when the launcher could reach them. Each symptom appeared local, but the durable decision is one terminal-reading model: a small inspectable palette, status-led cards with recessed bodies, content-independent transcript folding, and workspace-aware navigation.
|
||||
|
||||
## Decision
|
||||
|
||||
### Palette
|
||||
|
||||
`paletteSpec(scheme)` is the single table of SGR codes, close codes, and purposes. `createPalette` derives every wrapper from it and `/palette` prints the same table in the running terminal. Components do not emit their own SGR sequences except for the fixed startup brand gradient. Every close resets every SGR group its open sets.
|
||||
|
||||
Duplicate roles are merged: `muted` into `dim`, `added` into `success`, `removed` into `error`, and the unused second accent is removed. `dim` uses `2;39` and closes with `22;39` on both schemes so recessed text stays relative to the terminal foreground rather than becoming a fixed heavy gray on light backgrounds. Colors and attributes are branded separately in TypeScript, allowing attribute/color composition while rejecting nested colors whose reset would discard the outer color.
|
||||
|
||||
### Tool cards
|
||||
|
||||
A tool card has one colored `Tool / <name>` status header over one dim body. Presenter titles, terminal commands and cwd rows, output, XML text, and fold markers use that body tone. Diff colors remain because red and green carry meaning, and signal markers remain errors.
|
||||
|
||||
`renderUnknownXml` receives an explicit body styler for unknown tool results. Terminal presenters parse and remove the model-facing final exit or signal marker before returning `TerminalResultView.output`; the TUI renders the structured status once as its own pill. Truncation, timeout, and sandbox lines remain in the body because the pill does not represent them.
|
||||
|
||||
### Injected context and folding
|
||||
|
||||
Injected context renders as prose in `ContextCardComponent`, not through the XML tree renderer. Exact matched outer `<system-reminder>` lines are stripped, but mismatched, unpaired, or inline tag-like text remains verbatim. Model-facing content is unchanged. Folding uses the shared `preview` helper after body assembly, so it depends only on row count, never parser success or payload characters.
|
||||
|
||||
`Ctrl+O` cycles collapsed, expanded, and hidden. Tool cards disappear in the hidden state together with their card-owned leading gap. Context cards participate in collapsed and expanded states but fall back to collapsed while tools are hidden, because injected instructions are not disposable tool traffic.
|
||||
|
||||
### Cross-workspace resume
|
||||
|
||||
The resume picker summarizes all records and owns a current-workspace/all-workspaces scope toggled with Tab. It defaults to the current workspace, adds workspace labels only in the broader scope, and refuses records without a cwd because there is no directory to enter.
|
||||
|
||||
`TuiResumeHost.handoff` receives the selected `SessionId` and the cwd re-read during preflight. The CLI changes directory before disposing the current app, so an unreachable directory fails while the terminal can still recover; `execve` then inherits the selected workspace. The launcher also supplies the exit message rather than asking the TUI to reconstruct launcher syntax.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Keep separate notes and local fixes for each visual symptom.** Rejected: the decisions share one reading hierarchy and repeatedly superseded each other. One owner makes the final palette, card, context, and navigation rules clear without requiring readers to reconstruct chronology.
|
||||
|
||||
**Keep aliases and enforce presentation by convention.** Rejected: aliases imply distinctions that do not exist, and nested color resets or incomplete SGR closes fail silently. A single table plus types makes the contract inspectable and mechanically checked.
|
||||
|
||||
**Retain framing/output color splits inside tool cards.** Rejected: real cards mixed default foreground, cyan commands, dim cwd, unstyled XML, and dim output. The status header already provides the scan anchor; one recessed body removes noise. Diff colors are the narrow semantic exception.
|
||||
|
||||
**Parse or repair injected context as XML.** Rejected: reminder frames are prompting conventions around arbitrary prose containing raw ampersands, comparisons, and placeholder angle brackets. Repairing or escaping it would either guess structure or alter model-visible text.
|
||||
|
||||
**Hide context cards with tool cards.** Rejected: context carries injected instructions, not recoverable execution detail. The hidden phase therefore removes only tool traffic.
|
||||
|
||||
**Keep resume restricted to one workspace or infer cwd after boot.** Rejected: the restriction forces manual relaunch, while restored header cwd does not control filesystem and shell resolution. The target directory must cross the host seam before process replacement.
|
||||
|
||||
**Drop the TUI exit pill or remove model-facing exit markers.** Rejected: the pill is the scannable UI status, while the text marker is the model's status signal. The presenter consumes the marker when constructing the structured view so both audiences receive one representation.
|
||||
|
||||
## Consequences
|
||||
|
||||
The transcript reads as colored status headers over recessed detail, context presentation is stable for arbitrary prose, and one shortcut controls transcript density. The public `TuiTheme.muted` role is removed; extensions use `dim`. The palette and `renderUnknownXml` contracts are stricter, adding small compile-time friction in exchange for preventing silent style loss.
|
||||
|
||||
Cross-workspace resume can move every path-resolving tool to another directory. A missing or inaccessible cwd prevents handoff. The broader picker also makes concurrent access to a shared session store easier to reach; cross-process session locking remains separate work.
|
||||
|
||||
The terminal presenter still treats a final output line exactly matching its exit-marker grammar as structured status, so a command that intentionally prints such a line can lose it from the card body. This residual is documented by `dsh-tool-bash`.
|
||||
|
||||
## Testing
|
||||
|
||||
TUI unit and keyless terminal snapshots cover palette enumeration, light/dark roles, legal and illegal style composition, uniformly dim card bodies, semantic diff colors, marker-free terminal output with one exit pill, prose-preserving context frames, content-independent folding, the three-state Ctrl+O cycle, model filtering, and both resume scopes. CLI handoff tests cover passing the re-read cwd and rejecting directory-entry failure before teardown. Tool-bash tests pin result-marker emission, parse, and stripping as one round trip.

# Agent Note: 统一的 TUI 呈现与导航
|
||||
|
||||
Status: implemented
|
||||
|
||||
[English](2026-07-28-consolidated-tui-presentation.md) | 中文
|
||||
|
||||
## Problem
|
||||
|
||||
终端 UI 逐步积累了多套彼此干扰的呈现规则：调色板角色互为别名，或在浅色终端中颠倒强调层级；工具卡片的框架、输出和退出标记重复或争夺注意力；注入上下文被当作 XML 解析，无法可靠折叠；`/resume` 即使能通过启动器访问其他工作区，也会排除不属于当前工作区的会话。每个症状看似局部，但持久决策只有一个终端阅读模型：精简且可检查的调色板、以状态为首且正文内收的卡片、与内容无关的记录折叠，以及感知工作区的导航。
|
||||
|
||||
## Decision
|
||||
|
||||
### 调色板
|
||||
|
||||
`paletteSpec(scheme)` 是 SGR 开始码、结束码和用途的唯一表。`createPalette` 从该表派生所有包装器，`/palette` 在运行中的终端打印同一张表。除固定的启动品牌渐变外，组件不自行发出 SGR 序列。每个结束码都重置对应开始码设置的所有 SGR 组。
|
||||
|
||||
重复角色被合并：`muted` 并入 `dim`，`added` 并入 `success`，`removed` 并入 `error`，未使用的第二强调色被移除。`dim` 在两种配色方案中都使用 `2;39`，并以 `22;39` 结束，使内收文本相对于终端前景色变暗，而不会在浅色背景上变成固定的深灰色。TypeScript 分别标记颜色和属性，允许属性与颜色组合，同时拒绝会因重置而丢失外层颜色的嵌套颜色。
|
||||
|
||||
### 工具卡片
|
||||
|
||||
工具卡片由一行带颜色的 `Tool / <name>` 状态标题和一块统一的 dim 正文组成。呈现器标题、终端命令及 cwd 行、输出、XML 文本和折叠标记都使用正文色调。差异颜色继续保留，因为红绿承载语义；信号标记也继续作为错误显示。
|
||||
|
||||
`renderUnknownXml` 对未知工具结果显式接收正文样式器。终端呈现器在返回 `TerminalResultView.output` 前解析并移除面向模型的末尾退出或信号标记；TUI 只把结构化状态呈现一次。截断、超时和沙箱信息继续留在正文中，因为状态标记不表达这些事实。
|
||||
|
||||
### 注入上下文与折叠
|
||||
|
||||
注入上下文由 `ContextCardComponent` 按普通文本呈现，不经过 XML 树渲染器。仅移除精确配对的外层 `<system-reminder>` 行；不匹配、单边或正文内类似标签的文本都原样保留。面向模型的内容不变。折叠在正文组装完成后使用共享 `preview` 辅助函数，因此只取决于行数，不依赖解析是否成功或载荷包含哪些字符。
|
||||
|
||||
`Ctrl+O` 在折叠、展开和隐藏之间循环。隐藏状态会连同卡片自有的前导间距一起移除工具卡片。上下文卡片参与折叠和展开状态，但工具隐藏时回到折叠状态，因为注入指令不是可丢弃的工具流量。
|
||||
|
||||
### 跨工作区恢复
|
||||
|
||||
恢复选择器汇总所有记录，并维护可用 Tab 切换的当前工作区/所有工作区范围。默认范围是当前工作区；只有更宽范围才显示工作区标签。没有 cwd 的记录会被拒绝，因为没有可进入的目录。
|
||||
|
||||
`TuiResumeHost.handoff` 接收选中的 `SessionId` 和预检时重新读取的 cwd。CLI 在释放当前应用前切换目录，因此无法访问的目录会在终端仍可恢复时失败；随后 `execve` 继承所选工作区。退出提示也由启动器提供，而不是让 TUI 反推启动器命令语法。
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**为每个视觉症状保留独立 Agent Note 和局部修复。** 否决：这些决策共享同一阅读层级，而且彼此多次取代。由一份记录统一拥有最终的调色板、卡片、上下文和导航规则，读者无需重建变更顺序。
|
||||
|
||||
**保留别名，并依靠约定执行呈现规则。** 否决：别名暗示并不存在的差异；嵌套颜色重置或不完整的 SGR 结束会静默失败。单一表格加类型约束使契约可检查且可机械验证。
|
||||
|
||||
**保留工具卡片内部的框架/输出颜色分层。** 否决：真实卡片会混用默认前景、青色命令、dim cwd、无样式 XML 和 dim 输出。状态标题已经提供扫描锚点；统一内收正文能消除噪声。差异颜色是狭窄的语义例外。
|
||||
|
||||
**把注入上下文继续解析或修复成 XML。** 否决：提醒框架只是包裹任意普通文本的提示约定，其中会包含原始 `&`、比较表达式和尖括号占位符。修复或转义要么猜测结构，要么改变模型可见文本。
|
||||
|
||||
**随工具卡片一起隐藏上下文卡片。** 否决：上下文承载注入指令，不是可恢复的执行细节。因此隐藏阶段只移除工具流量。
|
||||
|
||||
**把恢复限制在一个工作区，或在启动后推断 cwd。** 否决：前者迫使用户手动重启；后者恢复的会话头 cwd 并不控制文件系统和 shell 的路径解析。目标目录必须在进程替换前跨过主机接口。
|
||||
|
||||
**移除 TUI 退出状态标记，或移除面向模型的退出标记。** 否决：前者是便于扫描的 UI 状态，后者是模型的状态信号。呈现器在构造结构化视图时消费文本标记，使两类受众各看到一种表示。

记录现在表现为带颜色的状态标题和内收细节；上下文对任意普通文本都稳定呈现；一个快捷键控制记录密度。公共 `TuiTheme.muted` 角色被移除，扩展改用 `dim`。调色板和 `renderUnknownXml` 契约更严格，以少量编译期摩擦换取对静默样式丢失的防护。
|
||||
|
||||
跨工作区恢复会把所有依赖路径解析的工具移动到另一个目录。cwd 缺失或不可访问时不能交接。更宽的选择范围也使共享会话存储的并发访问更容易触达；跨进程会话锁仍是独立后续工作。

||||
|
||||
终端呈现器仍会把与退出标记语法完全一致的最后一行输出视为结构化状态，因此命令有意打印这种行时，卡片正文可能丢失该行。`dsh-tool-bash` 已记录这一残余限制。

||||
## Testing
|
||||
|
||||
TUI 单元测试和无密钥终端快照覆盖调色板枚举、浅色/深色角色、合法与非法样式组合、统一 dim 卡片正文、保留语义的差异颜色、仅有一个退出状态且正文无标记、普通文本上下文框架、与内容无关的折叠、Ctrl+O 三态循环、模型过滤和两种恢复范围。CLI 交接测试覆盖传递重新读取的 cwd，并在释放前拒绝目录切换失败。tool-bash 测试把结果标记的生成、解析和移除固定为同一轮往返契约。

# Agent Note: A capability-discriminated directory-picker seam for the web-GUI host
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-28-directory-picker-capability-seam.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The web GUI's "Open local folder" flow was hardwired to one interaction: `host.pickDirectory` invoked a native OS chooser compiled into `dsh-host-apiproxy` (private module, test-only injection seam). That shape cannot serve remote deployments — no OS dialog reaches a browser on another machine — and the planned in-app directory browser (Figma `Harness` 802-56979) needs listing/creation primitives, which are a different interaction contract, not a different implementation of the same one. Swapping interactions required editing gateway source, against the repo's everything-is-a-plugin stance.
|
||||
|
||||
## Decision
|
||||
|
||||
A three-package capability seam in `packages/host/` — `directory-picker` (interface), `directory-picker-native`, `directory-picker-browse` (backends) — with one contract method: `capability()` returns a **discriminated union**, `{ kind: 'native', pick(signal) }` or `{ kind: 'browse', list(path?), createDirectory(path, name) }`. The gateway (`dsh-host-apiproxy`) injects `directoryPicker`, serves the matching RPCs, and answers `directory-picker-unavailable` for the other kind. The union is discriminated because the backends differ in *interaction shape* — flattening them into one method set would force every backend to fake the other's shape.
|
||||
|
||||
**The client side is slot-composed, not advertisement-branched.** ui-workspace's two trigger surfaces each declare a `single` directory-flow hole (`conversation.hero.workspace.directoryFlow` / `sidebar.workspaces.directoryFlow`; two keys because a hole has exactly one declaring slot entry — same owner contract, same occupant). Backend packages are **dual-face**: the browser half registers the matching interaction into both holes — `-native` a renderless occupant driving `host.pickDirectory`, `-browse` the in-app Select Workspace Directory dialog. The hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`) carries the whole exchange: ui-workspace keeps the trigger (menu entry rendered only while the hole is occupied) and the adoption (`createWorkspace({path})`, conflict/error dialog, Choose again), the occupant owns everything between `open` and the picked path. One `cordis.yml` row therefore swaps the host capability and the client flow together; a mismatch is impossible by construction, and mounting two flow packages fails at client load (`single` hole). The earlier `host.describe.directoryPicker` advertisement and the client's kind branching are deleted — with composition wiring both sides, a wire fact for the client to branch on had no remaining consumer. The hole registry (`ctx.slots.entries`) replaces it as the per-menu-open occupancy read.
|
||||
|
||||
Placement and policy rulings folded into this decision:
|
||||
|
||||
- **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
|
||||
- **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
|
||||
- **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the planned show-hidden toggle becomes a client-only change. Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
|
||||
- **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
|
||||
- **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
|
||||
- **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.
|
||||
- **The native backend stays.** Plugin-form was the point: multiple providers can serve the seam (an Electron shell would provide the `native` interaction through its own dialog API). Kind naming: `dialog` was the first pick and was dropped — the browse interaction also presents a dialog (the in-app modal), so the word failed to discriminate; `native` names where the chooser runs.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
- **Extend `ctx.fs` with browse methods.** Rejected: authority-domain coupling above; also a listing-for-display contract (hidden flags, crumbs, home anchor) does not belong on a storage seam.
|
||||
- **One uniform seam method set (`pick(): path`).** Rejected: an in-app browser cannot be served behind a single host-side call — the browsing loop lives in the client and needs primitives on the wire; the native chooser cannot implement primitives. The interaction difference is irreducible, hence the discriminant.
|
||||
- **Direct stdlib calls inside apiproxy (no seam).** Rejected: keeps the gateway the only swap point (source edits), loses fixture/test backends, and contradicts the plugin doctrine that motivated the work.
|
||||
- **Adopting a file-manager/drive-enumeration dependency.** Rejected per the survey above; recorded here as the dependency policy requires.
|
||||
|
||||
## Consequences
|
||||
|
||||
- `cordis.yml` chooses the interaction; `apps/cli` mounts `-browse` (the shipped default — remote-capable picking out of the box), one row having swapped backend and UI together; `-native` remains the host-display alternative.
|
||||
- The wire gains `host.listDirectory`/`host.createDirectory` and four error codes; the connection fixture serves a deterministic browse tree and a deterministic `pickDirectory` path for keyless assembled tests.
|
||||
- A future interaction (or an Electron provider of the `native` interaction) is one dual-face backend package — no gateway surgery, no ui-workspace edits.
|
||||
- `ApiProxyDefaults.pickDirectory` (test-only injection) is gone; tests provide a stub `ctx.directoryPicker` like any other service.

# Agent Note：web GUI 宿主的能力可辨识目录选择 seam
|
||||
|
||||
状态：已实现
|
||||
|
||||
[English](2026-07-28-directory-picker-capability-seam.md) | 中文
|
||||
|
||||
## 问题
|
||||
|
||||
web GUI 的"打开本地文件夹"流程被焊死在一种交互上：`host.pickDirectory` 调用编译进 `dsh-host-apiproxy` 的原生 OS 选择器（私有模块，仅测试注入缝）。这个形态服务不了远程部署——没有任何 OS 对话框能弹到另一台机器的浏览器里——而计划中的应用内目录浏览器（Figma `Harness` 802-56979）需要列举／创建原语，那是**另一种交互契约**，不是同一契约的另一种实现。想换交互只能改网关源码，违背仓库"一切皆插件"的立场。
|
||||
|
||||
## 决策
|
||||
|
||||
在 `packages/host/` 落一个三包能力 seam——`directory-picker`（接口）、`directory-picker-native`、`directory-picker-browse`（后端）——唯一契约方法 `capability()` 返回**可辨识联合**：`{ kind: 'native', pick(signal) }` 或 `{ kind: 'browse', list(path?), createDirectory(path, name) }`。网关（`dsh-host-apiproxy`）注入 `directoryPicker`，提供对应的 RPC，另一种 kind 的调用以 `directory-picker-unavailable` 应答。联合之所以可辨识，是因为后端差异在**交互形态**——压平成统一方法集会逼每个后端伪装另一方的形态。
|
||||
|
||||
**client 侧靠 slot 组合，而非按广播分支。** ui-workspace 的两个触发表层各自声明一个 `single` 目录流洞（`conversation.hero.workspace.directoryFlow`／`sidebar.workspaces.directoryFlow`；之所以是两个 key，是因为一个洞只有一个声明它的 slot entry——owner 契约相同、占用者相同）。后端包是**双面包**：browser half 把匹配的交互注册进两个洞——`-native` 是驱动 `host.pickDirectory` 的无渲染占用者，`-browse` 是应用内的选择工作区目录对话框。洞的 owner 会话（`open`/`busy`/`onPicked`/`onCancel`/`onError`）承载整个交换：ui-workspace 保留触发（菜单入口仅在洞被占用时渲染）与接纳（`createWorkspace({path})`、冲突／错误对话框、重新选择），占用者持有从 `open` 到所选路径之间的一切。因此一行 `cordis.yml` 同时切换宿主能力与 client 流程；错配在构造上不可能，同时挂两个流程包会在 client 加载期失败（`single` 洞）。早先的 `host.describe.directoryPicker` 广播与客户端 kind 分支被删除——组合已经接好两侧后，供客户端分支用的 wire 事实不再有任何消费者。洞注册表（`ctx.slots.entries`）取而代之，成为每次打开菜单的占用读取。
|
||||
|
||||
并入本决策的位置与策略裁决：
|
||||
|
||||
- **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。
|
||||
- **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
|
||||
- **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，计划中的"显示隐藏"开关变成纯客户端改动。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
|
||||
- **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
|
||||
- **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。
|
||||
- **全盘可浏览，不做 roots 配置。** `workspace.create` 接受任意路径且 API 本就提供驱动 bash 的方法，浏览根只会是 UX 范围而非边界；没有消费方的可配置性过不了证据门槛。等到有部署需要再做。
|
||||
- **native 后端保留。** 插件化正是目的：多方都能提供该 seam（Electron 壳可以经自己的对话框 API 提供 `native` 交互）。kind 命名：最初选了 `dialog` 后被放弃——browse 交互同样以对话框呈现（应用内弹窗），这个词起不到判别作用；`native` 命名的是选择器运行的位置。
|
||||
|
||||
## 曾考虑的替代方案
|
||||
|
||||
- **给 `ctx.fs` 增加浏览方法。** 否决：上述权限域耦合；且面向展示的列举契约（hidden 标志、面包屑、home 锚点）不属于存储 seam。
|
||||
- **统一方法集的 seam（`pick(): path`）。** 否决：应用内浏览器无法藏在一次宿主侧调用后面——浏览循环在客户端，需要协议上的原语；而对话框实现不了原语。交互差异不可约，故用判别标签。
|
||||
- **apiproxy 里直接调标准库（不建 seam）。** 否决：换装点仍是改网关源码，失去 fixture／测试后端，与促成这项工作的插件教义相悖。
|
||||
- **引入文件管理器／盘符枚举依赖。** 按上文调研否决；依赖政策要求记录于此。
|
||||
|
||||
## 后果
|
||||
|
||||
- `cordis.yml` 决定交互形态；`apps/cli` 挂 `-browse`（随附默认——开箱即得可远程的选取），一行同时切换了后端与 UI；`-native` 仍是宿主屏幕方案。
|
||||
- 协议新增 `host.listDirectory`／`host.createDirectory` 与四个错误码；connection fixture 提供确定性浏览树与确定性 `pickDirectory` 路径供无密钥组装测试使用。
|
||||
- 未来的新交互（或提供 `native` 交互的 Electron 实现）只是一个双面后端包——无需网关手术，也不动 ui-workspace。
|
||||
- `ApiProxyDefaults.pickDirectory`（仅测试注入）删除；测试像提供其他服务一样提供 stub `ctx.directoryPicker`。

# Agent Note: Native TypeScript source launch for dsh
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-28-dsh-native-typescript-source-launch.zh.md)
|
||||
|
||||
> The Node-native launch vector is superseded by [dsh source launch through the tsx ESM hook](2026-07-29-dsh-source-launch-tsx-esm.md): Node 26.0.0 removed `--experimental-transform-types`, and the paths loader described here is deleted. The Cordis-config declaration gate (`verify-cordis-config`), the app-boot fail-loud plugin diagnostic, and the vendored `import type` marks remain current.
|
||||
|
||||
## Problem
|
||||
|
||||
The `dsh` source entry point originally used `tsx` to run `apps/cli/src/bin.ts`, with the same third-party loader implicitly handling both TypeScript transformation and the root tsconfig's `paths` resolution. With Node handling TypeScript natively, it does not apply tsconfig path mappings; resolving through package exports would instead mix potentially stale or nonexistent `lib/` artifacts into the source launch.
|
||||
|
||||
Node's transform also does not perform type analysis. A type imported through an ordinary value import remains a runtime ESM request, and TypeScript's `export =` becomes a CommonJS assignment rather than an ESM default export. The source graph therefore has to use explicit type-only imports and native ESM exports; a resolve hook cannot repair incompatible source syntax.
|
||||
|
||||
Cordis configuration introduces a separate resolution boundary. Bare plugins in `cordis.yml` do not pass through TypeScript import analysis, so their resolver manifest may omit the required dependencies. The Cordis Loader logs plugin import errors and leaves an entry without a fiber, but does not fail startup itself; a typo in the configuration can therefore produce an incomplete application with exit code 0.
|
||||
|
||||
## Decision
|
||||
|
||||
The `dsh` TUI, Web, and headless source launches use `node --experimental-transform-types`; Node performs TypeScript transformation without loading `tsx` or esbuild. `bin/dsh`, the root-level `dsh`/TUI/Web demos, and Code Mode TUI enter the same `apps/cli/src/bin.ts` launch chain. Test and E2E launchers retain their existing strategies, and the built `lib/bin.js` continues to run under ordinary Node.
|
||||
|
||||
`scripts/tspath-loader.ts` registers only a module resolve hook. It uses `TSX_TSCONFIG_PATH` when set (resolving relative values from the invoking cwd) and otherwise reads the root `tsconfig.json`; `TsconfigPathsResolver` follows that config's `extends` chain through the repository's existing TypeScript development tool, selects exact or wildcard `paths` entries according to tsconfig rules, and maps matching workspace bare specifiers to `.ts`/`.mts`/`.cts` source files or directory index files. Node remains solely responsible for code transformation. The source-only loader is not part of the built CLI and `apps/cli` does not declare `typescript` as a runtime dependency.
|
||||
|
||||
Source imports are redirected only when the target package is either the nearest package manifest's own name or one of that manifest's declared runtime dependencies. The Cordis Loader uses the configuration directory URL as the import parent; the resolver then searches upward for the workspace manifest that declares the plugin, so dependency ownership for `examples/tui-agent/cordis.yml` lies with `examples/package.json`, and dependency ownership for `apps/cli/cordis.yml` lies with `apps/cli/package.json`. Specifiers that do not match tsconfig paths, refer to undeclared dependencies, or are not bare all fall back to Node's default resolution.
|
||||
|
||||
`verify-cordis-config` performs a one-way completeness check on both resolver manifests: every bare plugin package in a configuration must appear in the corresponding manifest's `dependencies`, while the manifest may contain extra dependencies not referenced by that configuration. The root `AGENTS.md` makes updating the configuration and dependencies together a standing rule.
|
||||
|
||||
After the Loader settles, the shared `dsh-app-boot` checks every enabled entry that has no fiber and rejects startup with `plugin(s) failed to load: ...; Cordis startup failed because these plugin(s) could not be resolved`, listing all failed plugins. This diagnostic lives at the app layer and does not change the vendored Loader's startup behavior.
|
||||
|
||||
Node-compatible TypeScript is part of this source-launch contract. Vendored Cordis, Loader, Include, HMR, and Schemastery mark erased imports with `import type`. Schemastery uses a native ESM default export and declares `type: module`; its `.mjs` and `.cjs` build outputs retain the existing ESM-default and callable-`require()` behavior. These divergences are recorded in `vendor/README.md`; no runtime behavior is added to the vendored frameworks.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Continue using `tsx`.** Rejected because `tsx`/esbuild would continue to own TypeScript transformation, so this launch chain could not prove that Node's native transformation works.
|
||||
|
||||
**Load the built `lib/` through package exports from the source entry point.** Rejected because this would mix the source plane with the artifact plane; a zero-build development launch could read stale artifacts or fail outright.
|
||||
|
||||
**Apply the root tsconfig `paths` unconditionally.** Rejected because this would allow undeclared cross-package imports and Cordis plugins to keep resolving, hiding mismatches between the manifest and the actual runtime graph.
|
||||
|
||||
**Transform imports inside the custom loader.** Rejected because type-aware source rewriting would reintroduce a compiler-style transform and make the loader, rather than Node, responsible for TypeScript execution. Making the checked-in source Node-compatible keeps the launch boundary explicit.
|
||||
|
||||
## Consequences
|
||||
|
||||
- TUI/headless retain a zero-build source loop, while Web still builds its frontend artifacts before starting the CLI source entry. TypeScript syntax passes only through Node's native transform; the URL-only loader uses the checkout's root development dependencies and adds no CLI runtime dependency.
|
||||
- Workspace package imports and Cordis configuration dependencies must both be declared explicitly in the resolver manifest; the static gate prevents configuration from landing before its dependencies, while extra dependencies are not errors.
|
||||
- Plugin import failures no longer leave an incomplete application with exit code 0; the final error identifies both the Cordis startup failure and the specific plugin names, while the Loader's original error remains earlier in the logs.
|
||||
- Vendored source in the CLI graph must remain compatible with Node's transform-types module semantics; the local-modification log makes the upstream sync obligation explicit.
|
||||
- CI's `lib` mode, test/E2E launchers, and other example launchers retain their existing strategies; this native source loader covers only the `dsh` CLI application chain.

# Agent Note: dsh 原生 TypeScript 源码启动
|
||||
|
||||
Status: implemented
|
||||
|
||||
[English](2026-07-28-dsh-native-typescript-source-launch.md) | 中文
|
||||
|
||||
> Node 原生启动向量已被 [dsh 通过 tsx ESM hook 源码启动](2026-07-29-dsh-source-launch-tsx-esm.md) 取代：Node 26.0.0 移除了 `--experimental-transform-types`，本文描述的 paths loader 已删除。Cordis 配置声明门禁（`verify-cordis-config`）、app-boot 的 fail-loud 插件诊断以及 vendor 中的 `import type` 标注仍然有效。
|
||||
|
||||
## 问题
|
||||
|
||||
`dsh` 源码入口原本使用 `tsx` 运行 `apps/cli/src/bin.ts`，TypeScript 转换和根 tsconfig 的 `paths` 解析都由同一个第三方 loader 隐式处理。改由 Node 原生处理 TypeScript 后，Node 不会应用 tsconfig 路径映射；如果改为通过包导出解析，源码启动会混入可能陈旧或不存在的 `lib/` 产物。
|
||||
|
||||
Node 的转换也不执行类型分析。通过普通值 import 导入的类型会保留为运行时 ESM 请求，而 TypeScript 的 `export =` 会变成 CommonJS 赋值，而不是 ESM default export。因此，源码图必须显式使用仅类型导入和原生 ESM 导出；resolve hook 无法修复不兼容的源码语法。
|
||||
|
||||
Cordis 配置还引入了另一条解析边界。`cordis.yml` 中的 bare plugin 不经过 TypeScript import 分析，其解析方 manifest 可能漏掉所需依赖。Cordis Loader 会记录插件 import 错误，并留下没有 fiber 的 entry，但不会让启动本身失败；配置中的拼写错误因此可能得到退出码为 0 的残缺应用。
|
||||
|
||||
## 决策
|
||||
|
||||
`dsh` 的 TUI、Web 和无头源码启动使用 `node --experimental-transform-types`，由 Node 完成 TypeScript 转换，不加载 `tsx` 或 esbuild。`bin/dsh`、根级 `dsh`/TUI/Web demo 以及 Code Mode TUI 都进入同一条 `apps/cli/src/bin.ts` 启动链路。测试与 e2e 启动器保留各自现有策略，构建后的 `lib/bin.js` 继续由普通 Node 运行。
|
||||
|
||||
`scripts/tspath-loader.ts` 只注册一个模块 resolve hook。设置 `TSX_TSCONFIG_PATH` 时，它会使用该路径（相对路径从调用方的 cwd 解析），否则读取根 `tsconfig.json`；`TsconfigPathsResolver` 使用仓库已有的 TypeScript 开发工具沿该配置的 `extends` 链解析，按 tsconfig 规则选择精确或 wildcard `paths` 条目，并将命中的 workspace bare specifier 映射到 `.ts`/`.mts`/`.cts` 源文件或目录 index 文件。代码转换始终只由 Node 负责。该源码专用 loader 不属于构建后的 CLI，`apps/cli` 也不会把 `typescript` 声明为运行时依赖。
|
||||
|
||||
只有当目标包是最近 package manifest 的自身名称或其已声明的运行时依赖时，源码 import 才会重定向。Cordis Loader 使用配置目录 URL 作为 import parent；此时 resolver 会向上查找声明该插件的 workspace manifest。因此，`examples/tui-agent/cordis.yml` 的依赖由 `examples/package.json` 持有，`apps/cli/cordis.yml` 的依赖由 `apps/cli/package.json` 持有。未命中 tsconfig paths、引用未声明依赖或不是 bare specifier 的说明符全部交回 Node 默认解析。

||||
`verify-cordis-config` 对这两个解析方 manifest 执行单向完整性检查：配置中的每个 bare plugin package 都必须出现在对应 manifest 的 `dependencies` 中，manifest 可以包含该配置未引用的额外依赖。根 `AGENTS.md` 将同步更新配置和依赖定为常驻规则。
|
||||
|
||||
Loader 完成结算后，共享的 `dsh-app-boot` 会检查每个已启用但没有 fiber 的 entry，并以 `plugin(s) failed to load: ...; Cordis startup failed because these plugin(s) could not be resolved` 拒绝启动，同时列出全部加载失败的插件。该诊断位于应用层，不改变 vendor 中 Loader 的启动行为。
|
||||
|
||||
Node-compatible TypeScript 是这项源码启动契约的一部分。vendor 中的 Cordis、Loader、Include、HMR（热模块替换）和 Schemastery 使用 `import type` 标记会被擦除的导入。Schemastery 使用原生 ESM default export 并声明 `type: module`；其 `.mjs` 和 `.cjs` 构建产物分别保留现有的 ESM default export 行为和 `require()` 返回可调用值的行为。这些差异记录在 `vendor/README.md` 中；没有为 vendor 中的框架新增运行时行为。
|
||||
|
||||
## 曾考虑的替代方案
|
||||
|
||||
**继续使用 `tsx`。** 不采用，因为 `tsx`/esbuild 会继续负责 TypeScript 转换，本启动链路无法因此证明 Node 原生转换可用。
|
||||
|
||||
**让源码入口通过包导出加载构建后的 `lib/`。** 不采用，因为这会混合 source plane 与 artifact plane；零构建开发启动可能读取陈旧产物或直接失败。
|
||||
|
||||
**无条件应用根 tsconfig `paths`。** 不采用，因为这会让未声明的跨包 import 和 Cordis 插件继续成功解析，从而掩盖 manifest 与实际运行图之间的不一致。
|
||||
|
||||
**在自定义 loader 内转换 import。** 不采用，因为感知类型的源码改写会重新引入编译器式转换，并让 loader 而非 Node 负责执行 TypeScript。使签入仓库的源码兼容 Node，可以让启动边界保持显式。
|
||||
|
||||
## 后果
|
||||
|
||||
- TUI／无头界面保留零构建源码回路，Web 仍会在启动 CLI 源码入口前构建前端产物。TypeScript 语法只经过 Node 原生转换；仅处理 URL 的 loader 使用 checkout 根目录的开发依赖，不增加 CLI 运行时依赖。
|
||||
- workspace package import 和 Cordis 配置依赖都必须在解析方 manifest 中明确声明；静态门禁防止配置先于依赖落地，额外依赖不构成错误。
|
||||
- 插件 import 失败不再留下退出码为 0 的残缺应用；最终错误同时说明 Cordis 启动失败及具体插件名，Loader 的原始错误仍会保留在更早的日志中。
|
||||
- CLI 源码图中的 vendor 源码必须与 Node 的 transform-types 模块语义兼容；本地修改记录明确了上游同步义务。
|
||||
- CI 的 `lib` 模式、测试／e2e 启动器和其他示例启动器保留各自现有策略；该原生源码 loader 只覆盖 `dsh` CLI 应用链路。

# Agent Note: Create every message as an identified immutable value
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-28-identified-immutable-message-values.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The harness had several message-shaped representations with different identity rules. Agent input acquired an inbox correlation id only when the loop accepted it, while durable user messages, assistant messages, tool results, and model-request messages could have no identity. Prompt admission therefore sat between creation and identity, and equivalent content was copied across live events, durable events, and model requests without one value that named the message throughout its lifetime.
|
||||
|
||||
This made identity a routing side effect rather than a message invariant. Producers could not refer to a message before calling the agent, prompt hooks received content and source separately, and later projections had to reconstruct a message while deciding whether an id existed. Immutability also began at different boundaries: some inputs were frozen by the loop, some only by session append, and provider-produced assistant output used a separate provenance-bearing shape.
|
||||
|
||||
## Decision
|
||||
|
||||
`@deepseek-ai/dsh-llm` owns one `Message` value with required `id`, `role`, `content`, and `source`. `MessageId` is opaque and shared by user, assistant, and tool-result messages. A message receives its id at creation, before routing, prompt admission, durable append, or request projection. The same id survives every representation boundary.
|
||||
|
||||
`createMessage(input)` is the canonical role-generic creation boundary. It mints a `MessageId`, detaches the supplied role, content, and source, and deep-freezes the complete value before returning it. `createUserMessage({ content, source })` fixes the user role for prompt and context producers. `createAssistantMessage({ content, source })` fixes both the assistant role and the model source kind, so model-output producers supply only content and model provenance. All creation helpers exclude an input id so callers cannot accidentally present creation as import. `freezeMessage(message)` is the separate import or transformation boundary: it detaches and deep-freezes a message whose identity already exists, without minting a replacement.
|
||||
|
||||
The helpers live in `dsh-llm` beside the base message vocabulary because their complete contracts depend only on that vocabulary. `createToolResultMessage()` belongs with the other creation helpers: it couples a tool call id to the exact user-role tool-result block and source without depending on session state or events. `dsh-session` consumes complete messages rather than owning their construction.
|
||||
|
||||
The `Agent` interface accepts a complete `UserMessage`. `send`, `followup`, `steer`, and `inject` never allocate or return identity; they freeze an imported value whose id the caller already holds. Prompt admission receives that message directly. A content rewrite creates a frozen replacement with the same id, while an additional context is a separately created `UserMessage` with its own id.
|
||||
|
||||
Durable message-producing events store complete messages. `user/message` stores its `UserMessage` directly; `assistant/message`, `tool/result`, and `steering/message` wrap their role-specialized message beside event-local position, usage, failure, or presentation facts. Session derivation returns those frozen values instead of reconstructing anonymous messages. Assistant assembly creates a model-sourced message when a response completes, and tool execution creates a tool-sourced message when a result is committed.
|
||||
|
||||
Any operation that changes only the representation of an existing semantic message preserves its id and returns another frozen value. An operation that creates a new semantic message mints a new id. Compaction content rewrites therefore preserve the rewritten tool-result identity, while a summary checkpoint is a new message.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Keep ids optional on the base message.** This would minimize fixture migration and allow provider or persistence shapes to remain anonymous. It would also preserve the original ambiguity: every consumer would need to branch on whether identity exists, and no type would prove that admission, logging, or projection retained it.
|
||||
|
||||
**Let `Agent.send()` allocate the id.** This keeps identity scoped to inbox correlation but makes the agent call the earliest point at which a producer can name its own message. Prompt construction, UI attachments, and synchronous enqueue/discard coordination then need content matching or an out-of-band token before `send()` returns.
|
||||
|
||||
**Let each durable event allocate a new id.** This gives persisted messages identities but deliberately breaks correlation with the live input and makes replayed requests appear to contain different messages. Identity belongs to the semantic value, not to each envelope that carries it.
|
||||
|
||||
**Freeze only at agent or session admission.** This avoids a creation helper but leaves an identified mutable interval in which caller code can change the meaning associated with an id. The decision makes “has an id” and “is an immutable snapshot” coincide.
|
||||
|
||||
## Consequences
|
||||
|
||||
Every message producer must choose creation or import explicitly, and tests construct complete values rather than partial content/source records. UUID generation moves outward to the first semantic creation point, so deterministic fixtures that provide an existing id use `freezeMessage()` instead of `createMessage()`.
|
||||
|
||||
Live inbox events, durable events, derived history, and model requests can correlate one message without content equality or envelope-specific ids. Prompt admission and UI attachment cleanup can compare `MessageId` before a turn exists. Deep freezing prevents a producer, hook, or observer from changing the value after identity is established.
|
||||
|
||||
The shared representation removes the old `UserMessageData`/`AgentMessage` split and folds provider provenance into typed message sources. Event envelopes still own facts that are not message semantics, such as turn and step position, token usage, internal tool failure identity, and presentation metadata.
|
||||
|
||||
The message and helper unit tests pin immediate identity, detachment, deep immutability, and preservation of an imported id. Agent-loop tests pin identity across admission, inbox lifecycle, durable append, content rewriting, and cancellation; session tests pin frozen derivation and identity-preserving replacement.

# Agent Note: 将每条消息创建为带标识的不可变值
|
||||
|
||||
Status: implemented
|
||||
|
||||

|
||||
## 问题
|
||||
|
||||
harness 曾存在多种形似消息的表示，各自采用不同的标识规则。agent（智能体）输入只有在 loop 接受后才会取得 inbox 关联 id，而持久用户消息、assistant 消息、工具结果和模型请求消息都可能没有标识。因此，提示词准入介于创建消息与建立标识之间；等价内容会在实时事件、持久事件和模型请求之间复制，却没有一个值能在消息的整个生命周期中标识它。
|
||||
|
||||
这使标识成为路由的副作用，而不是消息不变量。生产方无法在调用 agent 前引用一条消息，提示词钩子会分别接收内容和来源，后续投影则必须一边重建消息，一边决定 id 是否存在。不可变性也从不同边界开始：部分输入由 loop 冻结，部分直到会话追加时才冻结，提供方产生的 assistant 输出则使用另一种携带溯源信息的形状。
|
||||
|
||||
## 决策
|
||||
|
||||
`@deepseek-ai/dsh-llm` 持有唯一一种 `Message` 值，其 `id`、`role`、`content` 和 `source` 均为必填。`MessageId` 是不透明标识，由用户消息、assistant 消息和工具结果消息共享。消息在创建时就会获得 id，早于路由、提示词准入、持久追加或请求投影。同一个 id 会跨越每个表示边界。
|
||||
|
||||
`createMessage(input)` 是角色通用的规范创建边界。它会生成 `MessageId`，将输入的角色、内容和来源与输入分离，并在返回完整值前将其深度冻结。`createUserMessage({ content, source })` 为提示词和上下文生产方固定 user 角色。`createAssistantMessage({ content, source })` 同时固定 assistant 角色与模型来源类别，因此模型输出生产方只需提供内容和模型溯源信息。所有创建辅助函数的输入都不包含 id，因此调用方不会意外地把创建表达为导入。`freezeMessage(message)` 是独立的导入或转换边界：它会将已有标识的消息与输入分离并深度冻结，不会生成替代标识。
|
||||
|
||||
这些辅助函数位于基础消息词汇旁的 `dsh-llm` 中，因为它们的完整契约只依赖该词汇。`createToolResultMessage()` 与其他创建辅助函数同属此处：它使用同一个工具调用 id，将工具来源与确切的 user-role 工具结果块耦合起来，不依赖会话状态或事件。`dsh-session` 只消费完整消息，不负责构造它们。
|
||||
|
||||
`Agent` 接口接收完整的 `UserMessage`。`send`、`followup`、`steer` 和 `inject` 绝不会分配或返回标识；它们会冻结导入的值，而调用方已经持有该值的 id。提示词准入会直接接收该消息。改写内容时会创建具有相同 id 的冻结替代值，而每个附加上下文都是单独创建的 `UserMessage`，拥有自己的 id。
|
||||
|
||||
产生持久消息的事件会存储完整消息。`user/message` 直接存储其 `UserMessage`；`assistant/message`、`tool/result` 和 `steering/message` 则将各自角色专用的消息与事件本地的位置、用量、失败或呈现事实包装在一起。会话派生会返回这些冻结值，而不是重建匿名消息。assistant 组装会在响应完成时创建模型来源的消息，工具执行会在提交结果时创建工具来源的消息。
|
||||
|
||||
仅改变已有语义消息表示的操作会保留其 id，并返回另一个冻结值。创建新语义消息的操作则会生成新 id。因此，压缩（compaction）内容改写会保留被改写工具结果的标识，而摘要检查点是一条新消息。
|
||||
|
||||
## 考虑过的替代方案
|
||||
|
||||
**让基础消息的 id 保持可选。** 这能减少 fixture（测试前置数据）迁移，并允许提供方或持久化形状继续保持匿名，但也会保留原有歧义：每个消费方都必须根据标识是否存在执行分支，且没有任何类型能证明准入、记录或投影保留了标识。
|
||||
|
||||
**让 `Agent.send()` 分配 id。** 这会将标识限定在 inbox 关联范围内，却也会让 agent 调用成为生产方可以标识自身消息的最早时机。这样一来，在 `send()` 返回前，提示词构造、UI 附件和同步入队／丢弃协调都需要进行内容匹配，或使用带外 token。
|
||||
|
||||
**让每个持久事件分配新 id。** 这能为持久消息提供标识，却会有意切断它与实时输入的关联，并让回放请求表现得像包含了不同消息。标识属于语义值，而不是承载它的每个封装。
|
||||
|
||||
**只在 agent 或会话准入时冻结。** 这能省去创建辅助函数，却会留下一个带标识但可变的时间区间，调用方代码可以在这段时间内改变该 id 所关联的含义。本决策让「拥有 id」与「是不可变快照」同时成立。
|
||||
|
||||
## 后果
|
||||
|
||||
每个消息生产方都必须显式选择创建或导入，测试也会构造完整值，而不是不完整的内容／来源记录。UUID 的生成会前移至最初的语义创建点，因此提供已有 id 的确定性 fixture 会使用 `freezeMessage()`，而不是 `createMessage()`。
|
||||
|
||||
实时 inbox 事件、持久事件、派生历史和模型请求可以关联同一条消息，无需比较内容或使用封装专用 id。提示词准入和 UI 附件清理可以在轮次存在之前比较 `MessageId`。深度冻结可以防止生产方、钩子或观察方在标识建立后更改消息值。
|
||||
|
||||
共享表示移除了旧的 `UserMessageData`/`AgentMessage` 划分，并将提供方溯源信息纳入带类型的消息来源。事件封装仍持有不属于消息语义的事实，例如轮次与步骤位置、token 用量、内部工具失败标识和呈现元数据。
|
||||
|
||||
消息和辅助函数的单元测试会固定即时标识、输入分离、深度不可变性，以及导入 id 的保留。agent loop 测试会固定标识跨越准入、inbox 生命周期、持久追加、内容改写和取消的行为；会话测试会固定冻结派生和保留标识的替换行为。

> Supersedes [native TypeScript source launch](2026-07-28-dsh-native-typescript-source-launch.md): Node removed the capability that decision was built on.
|
||||
|
||||
## Problem
|
||||
|
||||
The [native source-launch decision](2026-07-28-dsh-native-typescript-source-launch.md) ran `apps/cli/src/bin.ts` under `node --experimental-transform-types` with a resolve-only paths loader, so Node owned TypeScript transformation. Node 26.0.0 removed `--experimental-transform-types` (the process rejects the flag with `bad option`), keeping only strip mode, and strip mode rejects syntax this source graph requires: vendored Cordis parameter properties (`constructor(private ctx: Context)`), the `@Inject` decorators in `vendor/hmr`, and runtime enums/namespaces throughout `vendor/` and `packages/workflow`. The repository's engines range (`^22.19.0 || >=24.0.0`) includes Node 26, so the native launch chain could not start at all there — and no CI job executed the real launch vector, so the incompatibility shipped silently.
|
||||
|
||||
Startup latency also mattered: the off-thread `module.register()` hooks worker serialized every resolution across threads (~440ms of `makeSyncRequest` wait during TUI boot), and the full tsx default (`--import tsx`) pays ~0.4s in its CJS hook's resolution amplification.
|
||||
|
||||
## Decision
|
||||
|
||||
The `dsh` TUI, Web, and headless source launches run `node --import tsx/esm`: tsx's ESM-only hook owns both TypeScript transformation and tsconfig `paths` projection. `bin/dsh`, the root `dsh`/`demo:tui`/`demo:web` scripts, and the Code Mode TUI overlay use the same vector; `bin/dsh` references the hook and tsconfig by absolute checkout paths (bare `tsx/esm` does not resolve from an arbitrary cwd) and pins `TSX_TSCONFIG_PATH` to the root tsconfig. The CJS hook stays off because the CLI source graph is ESM-only; measured TUI time-to-banner is ~0.7s versus ~1.1s under the full tsx default and ~0.75s under the removed native chain.
|
||||
|
||||
`scripts/tspath-loader.ts` and `apps/cli/src/tsconfig-paths-loader.ts` are deleted. With them went the loader's runtime rule of mapping a workspace import only for declared runtime dependencies — tsx applies the `paths` map unconditionally. Declaration completeness now rests on the static gates alone: `verify-cordis-config` for configured bare plugins, and workspace constraints for manifests. (That runtime rule found real bugs: `dsh-plan-mode` and `dsh-tool-tasks` imported `@deepseek-ai/dsh-llm` while declaring it only in devDependencies; fixed alongside this change.)
|
||||
|
||||
The node-compat CI matrix (Node 22.19 and 26) gains `dsh-source-launch-smoke` (`apps/cli/tests/source-launch.compat.spec.ts`): a keyless piped-stdio launch of the exact production vector asserting the non-zero-exit TTY refusal. Any future Node change to module hooks or TypeScript handling turns this gate red instead of breaking developers' `pnpm dsh`.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Keep the native chain on Node ≤25 and branch by version.** Rejected: two transformation semantics (amaro versus esbuild) diverge on edge syntax, the launcher grows version probing, and the node-compat matrix must cover both paths — heavy maintenance for an experimental flag that already changed under us. amaro also rejects the `@Inject` decorators `vendor/hmr` uses, so the native path could not boot the shipped default TUI config anyway.
|
||||
|
||||
**Make the source graph erasable-only so Node 26 strip mode accepts it.** Rejected: parameter properties and value namespaces pervade vendored Cordis/cosmokit/loader/schemastery; rewriting them is unbounded churn re-applied on every vendor sync.
|
||||
|
||||
**A repo-owned in-thread loader (`module.registerHooks()` + esbuild or `@swc/core` transform).** Rejected for now: prototypes measured ~0.45s (esbuild path untested end-to-end; SWC breaks on `vendor/hmr`'s decorator + namespace merge in both decorator modes), but it means owning transform correctness and a resolve hook that tsx already provides. Revisit only if the ~0.3s gap becomes a real cost; the profiling evidence lives in the PR discussion.
|
||||
|
||||
**Run built `lib/` for Node 26 and keep native for 24.** Rejected: loses the zero-build development loop on the newest Node line and mixes source and artifact planes.
|
||||
|
||||
## Consequences
|
||||
|
||||
- One launch vector across the whole engines range, including future Node lines that change native TypeScript support; the smoke gate enforces it per matrix line.
|
||||
- TypeScript transformation is delegated to tsx/esbuild again, reversing the prior note's goal of proving Node-native transformation; that goal is unreachable while vendored sources use non-erasable syntax and Node ships no transform mode.
|
||||
- The runtime declared-dependency enforcement in source launches is gone; undeclared workspace imports now surface only through static gates or built-mode resolution failures.
|
||||
- Startup improves ~0.4s over the full tsx default (`demo:headless` and ACP keep `--import tsx`; their graphs were not audited for CJS-hook dependence and their launch latency is not on the interactive path).

> 取代[原生 TypeScript 源码启动](2026-07-28-dsh-native-typescript-source-launch.md)：Node 移除了该决策所依赖的能力。
|
||||
|
||||
## 问题
|
||||
|
||||
[原生源码启动决策](2026-07-28-dsh-native-typescript-source-launch.md)让 `apps/cli/src/bin.ts` 在 `node --experimental-transform-types` 下运行，配合一个只做解析的 paths loader，由 Node 负责 TypeScript 转换。Node 26.0.0 移除了 `--experimental-transform-types`（进程以 `bad option` 拒绝该 flag），只保留 strip 模式，而 strip 模式无法接受这个源码图必需的语法：vendor Cordis 中的参数属性（`constructor(private ctx: Context)`）、`vendor/hmr` 中的 `@Inject` 装饰器，以及遍布 `vendor/` 与 `packages/workflow` 的运行时 enum/namespace。仓库的 engines 范围（`^22.19.0 || >=24.0.0`）包含 Node 26，因此原生启动链在其上完全无法启动——且没有任何 CI 任务执行过真实启动向量，这一不兼容悄然发布。
|
||||
|
||||
启动延迟同样是问题：off-thread 的 `module.register()` hooks worker 把每次解析都跨线程序列化（TUI 启动期间约 440ms 的 `makeSyncRequest` 等待），而完整 tsx 默认形态（`--import tsx`）的 CJS hook 解析放大要多付约 0.4s。
|
||||
|
||||
## 决策
|
||||
|
||||
`dsh` 的 TUI、Web 与无头源码启动运行 `node --import tsx/esm`：由 tsx 的 ESM-only hook 同时负责 TypeScript 转换与 tsconfig `paths` 投影。`bin/dsh`、根目录的 `dsh`/`demo:tui`/`demo:web` 脚本以及 Code Mode TUI overlay 使用同一向量；`bin/dsh` 以 checkout 的绝对路径引用 hook 与 tsconfig（裸的 `tsx/esm` 无法从任意 cwd 解析），并将 `TSX_TSCONFIG_PATH` 固定到根 tsconfig。CJS hook 保持关闭，因为 CLI 源码图是纯 ESM；实测 TUI 到 banner 约 0.7s，对比完整 tsx 默认形态约 1.1s、已移除的原生链约 0.75s。
|
||||
|
||||
`scripts/tspath-loader.ts` 与 `apps/cli/src/tsconfig-paths-loader.ts` 已删除。随之消失的还有该 loader "仅为已声明运行时依赖映射 workspace import" 的运行时规则——tsx 无条件应用 `paths` 映射。声明完整性现在仅由静态门禁保障：配置的裸插件走 `verify-cordis-config`，manifest 走 workspace constraints。（该运行时规则确实发现过真实缺陷：`dsh-plan-mode` 与 `dsh-tool-tasks` 导入 `@deepseek-ai/dsh-llm` 却只声明在 devDependencies；已随本变更修复。）
|
||||
|
||||
node-compat CI 矩阵（Node 22.19 与 26）新增 `dsh-source-launch-smoke`（`apps/cli/tests/source-launch.compat.spec.ts`）：以精确的生产启动向量做 keyless 管道 stdio 启动，断言非零退出的 TTY 拒绝。未来 Node 对模块 hook 或 TypeScript 处理的任何改动都会让该门禁变红，而不是破坏开发者的 `pnpm dsh`。
|
||||
|
||||
## 备选方案
|
||||
|
||||
**在 Node ≤25 保留原生链并按版本分叉。** 拒绝：两套转换语义（amaro 与 esbuild）在边缘语法上会分歧，启动器要加版本探测，node-compat 矩阵要覆盖两条路径——为一个已经变动过的 experimental flag 付出沉重维护。而且 amaro 也不支持 `vendor/hmr` 使用的 `@Inject` 装饰器，原生路径本来就无法启动随附的默认 TUI 配置。
|
||||
|
||||
**把源码图改成 erasable-only 以适配 Node 26 strip 模式。** 拒绝：参数属性与值 namespace 遍布 vendor 的 Cordis/cosmokit/loader/schemastery；改写是无界 churn，且每次 vendor sync 都要重做。
|
||||
|
||||
**仓库自有的同线程 loader（`module.registerHooks()` + esbuild 或 `@swc/core` 转换）。** 暂拒：原型实测约 0.45s（esbuild 路径未端到端验证；SWC 在 `vendor/hmr` 的装饰器 + namespace 合并上两种装饰器模式都会崩），但意味着自行负责转换正确性和一个 tsx 已经提供的 resolve hook。仅当约 0.3s 的差距成为真实成本时再重启；profiling 证据在 PR 讨论中。
|
||||
|

**Node 26 运行构建产物 `lib/`，24 保留原生。** 拒绝：在最新 Node 版本线上失去零构建开发循环，且混淆源码面与产物面。
|
||||
|
||||
## 结果
|
||||
|
||||
- 整个 engines 范围（包括未来改变原生 TypeScript 支持的 Node 版本线）只有一个启动向量；冒烟门禁按矩阵行强制执行。
|
||||
- TypeScript 转换重新委托给 tsx/esbuild，逆转了前一篇 note "证明 Node 原生转换可用" 的目标；在 vendor 源码使用不可擦除语法且 Node 不再提供 transform 模式的情况下，该目标不可达。
|
||||
- 源码启动中的运行时依赖声明强制不复存在；未声明的 workspace import 现在只能通过静态门禁或构建模式的解析失败暴露。
|
||||
- 启动相比完整 tsx 默认形态快约 0.4s（`demo:headless` 与 ACP 保持 `--import tsx`：其依赖图未就 CJS hook 依赖性做审计，且其启动延迟不在交互路径上）。

# Agent Note: Load sessions persisted before message identity
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-28-load-pre-identity-session-messages.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The identified immutable message change replaced four durable event payloads with complete message values. Existing v0 JSONL and SQLite sessions still held the immediately preceding shapes: direct `content`/`source` on user and steering events, `content`/`provenance` on assistant events, and `callId`/`content`/`isError` on tool results. Their headers still matched `SESSION_FORMAT_VERSION`, but current-shape validation rejected them before resume could construct a live `Session`.
|
||||
|
||||
Changing the message representation without a version bump made those logs indistinguishable at the header level from current v0 logs. The runtime needs a narrow import rule that restores data created by the supported first-party backends without weakening validation for unrelated obsolete or malformed events.
|
||||
|
||||
## Decision
|
||||
|
||||
`PersistenceCoordinator` normalizes the four exact pre-identity message payloads after backend decoding and before current message validation. It wraps their existing semantic fields in the current role-specific message shape and assigns `legacy-message:<session-id>:<event-seq>` as the deterministic imported `MessageId`. A legacy `tool/result` content replacement inherits the imported id of its replacement target, preserving the current content-only rewrite invariant.
|
||||
|
||||
The same normalization runs for `load`, `inspect`, an ownerless loaded state claiming its live session, and HMR prefix adoption. Prefix comparisons therefore compare the live current-shape seed with the same normalized stored view. Current-looking wrappers with missing or invalid fields are not repaired, and unsupported event vocabulary, request headers, versions, and surface relations retain their existing rejection paths.
|
||||
|
||||
The upgrade is read-only. Stored legacy records remain unchanged; a resumed session appends only current-shape events after them. Deterministic identities make repeated loads and a mixed legacy/current log reproduce the same message ids without a backend-specific rewrite transaction.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Reject the logs under the pre-release compatibility stance.** This is the default for unrelated v0 churn, but it strands real first-party sessions even though every old field maps unambiguously to the current message representation.
|
||||
|
||||
**Rewrite the complete stored log in place.** This would canonicalize the artifact but violate the append-only storage contract, require separate atomic replacement mechanisms for JSONL and SQLite, and expand a read compatibility fix into a migration system.
|
||||
|
||||
**Mint random ids on each load.** The messages would satisfy the type shape but lose stable identity across inspect, resume, restart, and mixed legacy/current appends.
|
||||
|
||||
## Consequences
|
||||
|
||||
Pre-identity JSONL and SQLite sessions resume with their original message content, sources, provider provenance, tool correlation, errors, metadata, and surface replacements. The returned events are otherwise indistinguishable from current imported message snapshots and remain deeply frozen.
|
||||
|
||||
This is one explicit same-version import exception, not a general v0 compatibility layer. Adding another exception requires another complete, unambiguous mapping at the persistence boundary; malformed current data continues to fail rather than being guessed into validity. The shared coordinator contract exercises the upgrade against the in-memory reference, JSONL, and SQLite backends, including deterministic reload and tool-result replacement identity.

# Agent Note: 加载消息标识机制引入前持久化的会话
|
||||
|
||||
Status: implemented
|
||||
|
||||
[English](2026-07-28-load-pre-identity-session-messages.md) | 中文
|
||||
|
||||
## 问题
|
||||
|
||||
带标识的不可变消息变更将四种持久事件载荷替换为完整消息值。现有的 v0 JSONL 和 SQLite 会话仍保留紧邻该变更之前的形状：用户事件和 steering（中途引导）事件直接携带 `content`/`source`，assistant 事件携带 `content`/`provenance`，工具结果则携带 `callId`/`content`/`isError`。这些会话的 header 仍与 `SESSION_FORMAT_VERSION` 匹配，但当前形状验证会拒绝它们，导致恢复流程无法构造实时 `Session`。
|
||||
|
||||
消息表示改变时没有提升版本，导致这些日志无法仅凭 header 与当前的 v0 日志区分。运行时需要一条范围受限的导入规则，既能恢复受支持的第一方后端所创建的数据，又不削弱对无关过时事件或格式错误事件的验证。
|
||||
|
||||
## 决策
|
||||
|
||||
`PersistenceCoordinator` 会在后端解码之后、当前消息验证之前，规范化消息标识机制引入前的四种特定消息载荷。它将载荷现有的语义字段包装进当前按角色区分的消息形状，并为其分配确定性的导入 `MessageId`：`legacy-message:<session-id>:<event-seq>`。旧版 `tool/result` 的内容替换会继承替换目标导入后的 id，从而保持当前仅改写内容的不变量。
|
||||
|
||||
同一项规范化也用于 `load`、`inspect`、无 owner 的已加载状态认领其实时会话，以及 HMR（热模块替换）前缀接管。因此，前缀比较会将实时的当前形状 seed 与同一份规范化存储视图进行比较。看似当前形状、但字段缺失或无效的包装层不会被修复；不受支持的事件词汇、请求 header、版本和 surface 关系仍沿用现有拒绝路径。
|
||||
|
||||
这项升级只发生在读取时。存储中的旧版记录保持不变；会话恢复后，只会在其后追加当前形状的事件。确定性标识使重复加载以及新旧形状混合的日志无需执行后端专用的重写事务，也能复现相同的消息 id。
|
||||
|
||||
## 考虑过的替代方案
|
||||
|
||||
**按照预发布兼容性立场拒绝这些日志。** 这是处理其他 v0 形状变动的默认方式，但即使每个旧字段都能明确映射到当前消息表示，它仍会导致真实的第一方会话无法恢复。
|
||||
|
||||
**就地重写完整的存储日志。** 这会使产物规范化，但违反仅追加存储契约，还需要为 JSONL 和 SQLite 分别实现原子替换机制，并将一次读取兼容性修复扩大为迁移系统。
|
||||
|
||||
**每次加载时随机生成 id。** 这些消息会满足类型形状，却无法在检查、恢复、重启以及新旧形状混合追加之间保持稳定标识。
|
||||
|
||||
## 后果
|
||||
|
||||
消息标识机制引入前的 JSONL 和 SQLite 会话可以恢复，并保留原始的消息内容、来源、提供方溯源信息、工具关联、错误、元数据和 surface 替换。除此之外，返回事件与当前导入的消息快照无法区分，并且仍然经过深度冻结。
|
||||
|
||||
这是一个显式的同版本导入例外，而非通用的 v0 兼容层。若要增加另一个例外，必须在持久化边界提供另一套完整且无歧义的映射；当前数据若格式错误，系统仍会拒绝，而不会猜测如何将其变成有效数据。共享协调器契约会针对内存参考实现、JSONL 和 SQLite 后端验证这项升级，包括重新加载时的确定性，以及工具结果替换时的标识继承。

# Agent Note: The scrollbar tokens get their consumer, and the workspace list reserves its gutter
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-28-themed-scrollbars-and-reserved-gutter.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
`design-platform.css` declares four `--dsw-alias-scrollbar-*` tokens (`bg-l1`, `bg-l2`, `hover-l1`, `hover-l2`) in both palettes, and no rule anywhere in the client read them. A defined token with no consumer is not a theme: every scrolling region rendered the user agent's own scrollbar, which knows nothing about the palette, so the dark theme showed a light native bar against dark surfaces.
|
||||
|
||||
The visible symptom that surfaced the gap was elsewhere. The workspace browser's session list (`.list` in `WorkspaceBrowser.module.css`) is the sidebar's only scrolling region, and each row's trailing content sits flush against the row's 8px right padding — `.time` in `rows/Rows.module.css` is `flex: none`, as are the action buttons that replace it on hover. An overlaid scrollbar therefore painted on top of the relative timestamp. Reserving space in that one list would have left the bar itself unthemed, so the two halves are one change.
|
||||
|
||||
## Decision
|
||||
|
||||
`packages/client/ui-theme/src/styles/scrollbar.css` is the sole consumer of the four tokens, and the fifth ui-theme sheet in the shell's import chain (`packages/client/web/src/base.css`). It follows `design-platform.css` there because it reads that sheet's tokens.
|
||||
|
||||
The rules sit on `body`, not `html`. `design-platform.css` declares the `--dsw-alias-*` tokens on `body`, with the dark overrides on `body[data-ds-dark-theme]`, and custom properties inherit only downward; an `html` rule resolves them to the guaranteed-invalid value, at which point `scrollbar-color` computes to `auto` and no theming happens at all.
|
||||
|
||||
`scrollbar-width` and `scrollbar-color` are declared on `body, body *` rather than once at the top. Inheritance would pass down the color already substituted at `body`, so a descendant rebinding the indirection could not change its own scrollbar; re-declaring makes each element substitute the variable as it sees it. `scrollbar-width` is not an inherited property in the first place, so it needs the per-element declaration regardless. The `::-webkit-scrollbar*` pseudo-elements are likewise not inherited and are matched unscoped.
|
||||
|
||||
The two renderings are mutually exclusive, and the exclusion is enforced rather than assumed. A non-`auto` `scrollbar-width` or `scrollbar-color` makes Chromium and Safari discard every `::-webkit-scrollbar*` rule for that element, `::-webkit-scrollbar-thumb:hover` included. Declaring both unconditionally therefore leaves the hover token rendering nowhere at all: 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. The standard properties consequently sit inside `@supports not selector(::-webkit-scrollbar)`, which is true only where the pseudo-element is unimplemented, so Firefox takes the standard path and WebKit-based engines take the pseudo-element path. The WebKit rules are not gated in turn: an engine without those pseudo-elements drops them as unknown selectors, so a gate would only restate what selector matching already does. An engine too old for the `selector()` function makes the condition invalid, which evaluates false and selects the pseudo-element path — the correct side for the pre-16.4 Safari that is the realistic case for that reading.
|
||||
|
||||
Both paths read one indirection pair, `--dsh-scrollbar-thumb` and `--dsh-scrollbar-thumb-hover`, bound on `body` to the l1 (base-surface) tokens. **This is the rebinding contract, and it is the part the CSS alone does not state**: an elevated surface 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, and that one rebind reaches the standard properties and the WebKit pseudo-elements together. The pair is rebound as a pair; rebinding the resting thumb alone leaves the hover state on the base-surface token. Eight surfaces rebind today: the command popup, the slash menu, the model-select panel, the settings panel, the shared `ui-primitives` menu card, the composer input card, the question composer card, and the todo panel. Most declare it on the elevated card rather than on the scrolling descendant, because the elevation is a property of the surface and custom properties inherit down to whichever child actually scrolls.
|
||||
|
||||
The last four were missed in the first implementation and found in review, which is why the rebinding contract is now checked mechanically rather than by inspection: a sheet that scrolls somewhere and paints an elevated surface somewhere must rebind.
|
||||
|
||||
The elevated set is resolved from the palette's own dark elevation ladder — the surface tokens whose dark value lands on `bg-layer-2` or `bg-layer-3`, which is the step the l1/l2 split encodes. Deriving it instead from the sheets that already rebind was the first attempt and is unsound: such a set can only confirm what someone already remembered, and a surface nobody has rebound yet — exactly the case the check exists for — defines itself as unelevated. `--dsw-specific-tip` proved it, resolving to the menu surface's rung while the todo panel scrolled on it unrebound and the derived check stayed green.
|
||||
|
||||
Scope is by token family, not by geometry: only `--dsw-alias-bg-*` and `--dsw-specific-*` name a surface. `--dsw-alias-button-*`, `--dsw-alias-interactive-*`, and `--dsw-alias-markdown-*` reach the same rungs while naming a control or an inline span that no scroll container renders its bar against. Shape cannot make that call, since a floating button legitimately carries a radius, a shadow, and a fixed size. The check is per sheet rather than per rule because the card and the descendant that scrolls are separate rules, and CSS text does not express which contains which.
|
||||
|
||||
The track and the corner stay transparent, so the thumb reads against whatever surface scrolls under it; only the thumb and its hover state carry a token color.
|
||||
|
||||
`.list` declares `scrollbar-gutter: stable`, which keeps the bar beside the rows instead of on top of them. `stable` rather than `auto` because `auto` reserves the gutter only while the list actually overflows: expanding a workspace group would then shift every row horizontally at the moment it starts scrolling. The reservation is unconditional and the rows never move.
|
||||
|
||||
The gutter and the sheet's `::-webkit-scrollbar` width are jointly necessary against an overlay scrollbar, which is the configuration where the symptom exists at all. Measured on the running app by deleting each from the live cascade with the other left in force: either deletion alone takes the list's band from 8 to 0. The gutter states that space be reserved, and the pseudo-element width is what makes chromium treat the bar as occupying layout space rather than floating over the content. Neither half of this change is therefore optional for the reported bug, which is a second reason the two halves ship together.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Per-module `::-webkit-scrollbar` rules in each scrolling component sheet.** Rejected: the client has thirteen scrolling containers across nine packages, every one would carry the same block, and the fourteenth would ship unthemed with nothing failing. A skin driven by design tokens belongs in the package that owns the tokens.
|
||||
|
||||
**An opt-in utility class that each scroll container adds.** Same duplication removed, but the failure mode stays: a new scroll container is themed only if its author remembers the class, and the omission is invisible in review. The `body, body *` form has no opt-in step to forget; a container that genuinely wants a different bar overrides the indirection, which is the same mechanism elevated surfaces use.
|
||||
|
||||
**Bind the properties on `html`.** The natural place for a document-wide skin, and it fails measurably: with the rule on `html` a scroll container computes `scrollbar-color: auto` in chromium, because the alias tokens are not in scope there.
|
||||
|
||||
**Declare the properties once and let them inherit.** Fewer matched elements, and it breaks the rebinding contract — inheritance carries the substituted color, not the variable reference, so an elevated surface could not retint its own scrollbar. It is also incomplete on its own terms, since `scrollbar-width` does not inherit.
|
||||
|
||||
**Declare the standard properties and the pseudo-elements unconditionally, without the `@supports` gate.** This is what the change originally shipped, and review caught it. Measured in chromium on probe elements with `scrollbar-gutter: stable` so the band is observable: an 8px `::-webkit-scrollbar` alone reserved a 30px band (the sheet's width plus the UA's buttons), and adding `scrollbar-width: thin` to the same element dropped it to the 10px `thin` reserves — the pseudo-element rules were being discarded, not merged. Every `::-webkit-scrollbar-thumb:hover` rule went with them, so both hover tokens and all four elevated surfaces' hover rebinds were dead code on the engine most users run.
|
||||
|
||||
**Gate the WebKit rules too, behind `@supports selector(::-webkit-scrollbar)`.** Symmetrical to read, and wrong in one direction: it would hide the rules from an engine that implements the pseudo-elements but not `selector()`, which is the pre-16.4 Safari the ungated form serves correctly. Unknown selectors are already dropped, so the gate adds no protection to pay for that.
|
||||
|
||||
**Pad the rows instead of reserving the gutter (extra right padding on `.list`, or moving `.time` inward).** Rejected: padding applies whether or not a bar is present, so it costs horizontal room in the common short-list case, and it fixes exactly one container while leaving every other scrolling region's content under its bar.
|
||||
|
||||
**`scrollbar-gutter: auto` on `.list`.** The reservation appears when the list overflows, which is when the bar exists. Rejected because the sidebar's lists grow and shrink as groups expand, so the reservation would appear and disappear under the user's cursor and shift the rows with it.
|
||||
|
||||
## Consequences
|
||||
|
||||
- Every scroll container in the client draws the themed thumb: `rgb(229, 229, 229)` on a light base surface, `rgb(60, 60, 61)` on a dark one, and `rgb(84, 85, 87)` for a dark elevated surface that rebinds to the l2 pair.
|
||||
- The two renderings are separately specified, so a change to the thumb's geometry or hover behavior has to be made twice — once in `scrollbar-width`/`scrollbar-color`, once in the pseudo-elements. Routing both through the indirection pair confines that duplication to the properties Firefox and WebKit do not share.
|
||||
- The hover tokens (`--dsw-alias-scrollbar-hover-l1`/`-l2`) render only on the pseudo-element path. Firefox states one thumb color through `scrollbar-color` and derives its own hover treatment, so a design change to the hover colors is visible in Chromium and Safari and not in Firefox. This is a limit of `scrollbar-color`, not of the sheet.
|
||||
- `body *` matches every element, for two properties whose effect the user agent already limits to elements that actually scroll. The cost is a broad selector; the alternative was a rebinding contract that does not work.
|
||||
- The workspace list is permanently narrower by the reserved band, at every list length. That is the trade the fix buys: stable row geometry instead of a timestamp that is legible only while the list is short.
|
||||
- There is no track token in the palette, so a design that later wants an opaque track needs a new alias token rather than a literal color in this sheet.
|
||||
|
||||
## Testing
|
||||
|
||||
Three unit specs read the CSS text on disk. `ui-theme/tests/scrollbar-styles.spec.ts` scans the scrollbar token set out of `design-platform.css` rather than hardcoding it, so adding, renaming, or dropping a token moves the assertions with it, and checks that every token has a consumer and that each elevated surface rebinds a complete pair. It also pins the path split by source offset: the standard properties inside the gate block, the `::-webkit-scrollbar*` rules and every read of the hover indirection outside it. That split needs an offset assertion because the spec's rule parser flattens through at-rules, so a gate deleted or a declaration moved across it leaves every other assertion in the file green.
|
||||
|
||||
`apps/web/tests/sidebar-scrollbar.e2e.ts` covers the facts only a real engine reports: the reserved band width, and which rendering path the engine took. It needs no model calls — the list only has to overflow — so it seeds cold sessions from an existing committed fixture read-only.
|
||||
|
||||
That scenario also commits a golden, `snapshots/sidebar-scrollbar/geometry.expected.md`, holding the resolved scrollbar style and geometry in both palettes. The aria goldens the other web scenarios commit cannot carry a CSS-only change: it alters no DOM and no accessible name, so their normalized trees are byte-identical with and without it. Recording the resolved values instead makes an unintended shift in thumb colour, band width, or rendering path a reviewable diff rather than a threshold someone has to reason about. Absolute coordinates are deliberately excluded — `timeRight` and the two edges depend on the sidebar's laid-out width and on font metrics, so committing them would produce a fixture that has to be re-recorded per platform and would document the platform rather than the change. What is recorded is the band, the overlap, and two orderings, each a difference or a comparison that survives any layout preserving the reservation.
|
||||
|
||||
Confirmed in headless chromium on the built client by reading computed values, which is what distinguishes a working token chain from a syntactically valid one: a scroll container computes the l1 thumb color in each palette, and a container that rebinds the indirection computes the l2 color, proving the rebind reaches the computed value rather than only the custom property. Firefox was verified the same way for the standard path, including the l1-to-l2 rebind on `scrollbar-color`; headless Firefox reports `scrollbar-width: none` on every element, styled or not, which is a headless artifact rather than an effect of the sheet.
|
||||
|
||||
Two chromium measurement limits shape what the e2e can assert. The gate makes chromium report `scrollbar-width` and `scrollbar-color` as `auto`, so the substituted `scrollbar-color` is no longer the observable — the e2e asserts the `auto` reading deliberately, since a concrete value there would mean the gate leaked and silenced the pseudo-elements. And `getComputedStyle(el, '::-webkit-scrollbar-thumb')` folds in the `::-webkit-scrollbar-thumb:hover` rule, so it reports the hover color at rest and pins neither state; proven by deleting the hover rule through `CSSStyleSheet.deleteRule` in the live page, which flipped that same query from the hover color to the resting one. The e2e therefore reads the resting and hover colors as the indirection variables resolve on the list — one throwaway probe element per variable, because `getComputedStyle` returns a live declaration and a reused probe reports only the last value read — and reads the hover declaration out of the cascade as rule text.
|
||||
|
||||
The gate itself has a negative control at the level it operates on: removing the `@supports` wrapper from the sheet, rebuilding `build:web`, and rerunning the e2e turns the `scrollbar-width: auto` assertion red with `thin`, which is the suppression the gate exists to prevent.
|
||||
|
||||
Headless chromium draws overlay scrollbars, and that is the configuration in which the reported symptom exists, so the e2e reproduces the bug rather than approximating it: against clean master the list's band is 0 and the bar covers 7px of the relative time. A reserved gutter there does not shrink `clientWidth`, so an assertion comparing the time element's right edge against the client-area edge holds with and without the reservation and would pass or fail on the platform's scrollbar style rather than on the declaration under test. The two signals that do separate the states are the `offsetWidth - clientWidth` band and `timeCoveredBy`, the overlap measured against the bar's own width.
|
||||
|
||||
Both are asserted because each catches a different regression, established by mutating one declaration at a time with the other assertions in that test silenced. Removing only the gutter leaves `timeCoveredBy` at 0 — the bar is then 8px and the row's right padding is also 8px, so it abuts the timestamp without covering it — and the band assertion is what fails. Removing the pseudo-element width as well, which is the actual master state, produces the overlap, and `timeCoveredBy` fails at 7. A headed run under xvfb cannot show the symptom in either state, because chromium paints a classic space-consuming bar there and `clientWidth` already excludes it.
|
||||
|
||||
Verifying browser-visible plugin CSS needs a rebuild `pnpm run build:web` does not perform. `WorkspaceBrowser.module.css` never reaches `apps/web/dist`: ui-workspace loads as a runtime plugin and its CSS is inlined into `packages/client/ui-workspace/lib/client.js`, built by that package's own `bundle` script. A negative control that reruns only `build:web` therefore exercises a stale bundle and passes with the declaration removed, which reads as a vacuous test rather than as an invalid control. Rebuild with `pnpm --filter @deepseek-ai/dsh-client-ui-workspace run bundle`, confirm the artifact by grepping `lib/client.js` for the declaration, then `build:web`.
|
||||
|
||||
`test:web` ran `build:web` alone, so every scroll-region or plugin-CSS change hit that trap; it now runs `build` first, which covers `packages/*/*` and so rebuilds the plugin bundles. `check-all` already ordered `build` before `build:web`, so CI was never exposed — only the local script was, which is exactly where a stale-bundle pass is most likely to be believed.

`design-platform.css` 在亮色与暗色两套调色板中都声明了四个 `--dsw-alias-scrollbar-*` token（`bg-l1`、`bg-l2`、`hover-l1`、`hover-l2`），而客户端里没有任何一条规则读取它们。定义了却无人消费的 token 构不成主题：所有滚动区域渲染的都是浏览器自带的滚动条，它对调色板一无所知，因此暗色主题下暗色表面上出现的是一条亮色的原生滚动条。
|
||||
|
||||
暴露这一缺口的可见症状出在别处。工作区浏览器的会话列表（`WorkspaceBrowser.module.css` 中的 `.list`）是侧边栏里唯一的滚动区域，而每一行的尾部内容都紧贴该行 8px 的右内边距——`rows/Rows.module.css` 中的 `.time` 取 `flex: none`，hover 时取代它的操作按钮也是如此。于是覆盖式滚动条会画在相对时间戳之上。只在这一个列表里预留空间，滚动条本身仍然没有主题，因此两部分合为一次变更。
|
||||
|
||||
## 决策
|
||||
|
||||
`packages/client/ui-theme/src/styles/scrollbar.css` 是这四个 token 的唯一消费方，也是壳的导入链（`packages/client/web/src/base.css`）中第五张 ui-theme 样式表。它排在 `design-platform.css` 之后，因为它读取那张样式表的 token。
|
||||
|
||||
规则挂在 `body` 上，而非 `html`。`design-platform.css` 在 `body` 上声明 `--dsw-alias-*` token，暗色覆盖挂在 `body[data-ds-dark-theme]` 上，而自定义属性只向下继承；挂在 `html` 上的规则会把它们解析为 guaranteed-invalid 值，此时 `scrollbar-color` 计算为 `auto`，主题完全不起作用。
|
||||
|
||||
`scrollbar-width` 与 `scrollbar-color` 声明在 `body, body *` 上，而不是只在顶层声明一次。继承传下去的是已经在 `body` 处代入完成的颜色值，因此后代元素重新绑定这层间接变量也无法改变自己的滚动条；逐元素重新声明使每个元素按它自己看到的取值代入变量。`scrollbar-width` 本身就不是可继承属性，无论如何都需要逐元素声明。`::-webkit-scrollbar*` 伪元素同样不继承，因此以不加限定的选择器匹配。
|
||||
|
||||
两种渲染互斥，而这种互斥是被强制的，不是假定的。`scrollbar-width` 或 `scrollbar-color` 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。因此无条件地同时声明会让 hover token 在任何地方都得不到渲染：实现了 hover 伪元素的引擎，恰恰就是被标准属性静音的那些，而 Firefox 没有 hover 伪元素可作退路。于是标准属性写在 `@supports not selector(::-webkit-scrollbar)` 之内，该条件只在伪元素未被实现处为真，因此 Firefox 走标准属性路径，WebKit 系引擎走伪元素路径。WebKit 规则不再反向加门禁：不实现这些伪元素的引擎会把它们当作未知选择器丢弃，因此加门禁只是重述选择器匹配本身已经做的事。对于旧到不支持 `selector()` 函数的引擎，该条件无效，从而求值为假并选中伪元素路径——对于这条判断下现实存在的 16.4 之前的 Safari，这正是正确的一侧。
|
||||
|
||||
两条路径都读取同一组间接变量 `--dsh-scrollbar-thumb` 与 `--dsh-scrollbar-thumb-hover`，它们在 `body` 上绑定到 l1（基础表面）token。**这就是重新绑定契约，也是单看 CSS 无法得知的部分**：抬升表面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)`，这一次重新绑定同时作用于标准属性和 WebKit 伪元素。这组变量必须成对重新绑定；只改静止态滑块会让 hover 状态仍留在基础表面的 token 上。目前有八处抬升表面做了重新绑定：命令浮层、斜杠菜单、模型选择面板、设置面板、`ui-primitives` 共用菜单卡片、输入条卡片、提问组件卡片与待办面板。多数把声明写在抬升卡片上而非滚动的后代元素上，因为抬升层级是这个表面的属性，而自定义属性会继承到真正滚动的那个子元素。
|
||||
|
||||
后四处在最初的实现里被漏掉、由评审发现，因此重新绑定契约现在由机械检查把关，而不再依赖人工审阅：一张样式表只要在某处滚动、又在某处绘制抬升表面，就必须重新绑定。
|
||||
|
||||
抬升表面集合是从调色板自身的暗色抬升阶梯解析出来的——暗色取值落在 `bg-layer-2` 或 `bg-layer-3` 上的那些表面 token，而这一档正是 l1/l2 之分所编码的层级差。最初的做法是从已经做了重新绑定的样式表反向推导，那是不成立的：这样得到的集合只能确认别人已经记得的部分，而尚无人重新绑定的表面——恰恰就是这项检查存在的理由——会把自己定义成「非抬升」。`--dsw-specific-tip` 证明了这一点：它解析到与菜单表面相同的那一档，待办面板在它上面滚动却没有重新绑定，而推导式的检查依然是绿的。
|
||||
|
||||
判定范围依据 token 家族而非几何形状：只有 `--dsw-alias-bg-*` 与 `--dsw-specific-*` 表述的是表面。`--dsw-alias-button-*`、`--dsw-alias-interactive-*` 与 `--dsw-alias-markdown-*` 会落到相同档位，但它们表述的是控件或行内片段，没有任何滚动容器会把滚动条画在它们之上。形状无法做这个判断，因为悬浮按钮本来就会带圆角、阴影和固定尺寸。这项检查以样式表为粒度而非以规则为粒度，因为卡片与真正滚动的后代元素是两条不同的规则，而 CSS 文本无法表达谁包含谁。
|
||||
|
||||
轨道与两条滚动条相交的角落保持透明，因此滑块是以其下滚动的任何表面为背景被看到；只有滑块及其 hover 状态带 token 颜色。
|
||||
|
||||
`.list` 声明 `scrollbar-gutter: stable`，使滚动条位于行的旁边而非行的上方。取 `stable` 而非 `auto`，因为 `auto` 只在列表确实溢出时才预留空位：那样展开一个工作区分组时，所有行会在列表开始滚动的那一刻发生水平位移。`stable` 的预留是无条件的，行不会移动。
|
||||
|
||||
面对覆盖式滚动条——也就是这个症状唯一存在的那种形态——空位声明与样式表里的 `::-webkit-scrollbar` 宽度是共同必要的。在运行中的应用上实测：保留其中一条、从活的层叠中删掉另一条，任意一次单独删除都会让列表的条带从 8 降到 0。空位声明表述的是「要预留空间」，而伪元素宽度才是让 chromium 把滚动条视为占据布局空间、而不是浮在内容之上的原因。因此对这个 bug 而言，本次变更的两半都不是可选项，这也是两半必须一起交付的第二个理由。
|
||||
|
||||
## 曾考虑的替代方案
|
||||
|
||||
**在每个滚动组件的样式表里各写一份 `::-webkit-scrollbar` 规则。** 之所以否决：客户端共有分布在九个包中的十三个滚动容器，每一个都要带上同一段规则，而第十四个会在没有任何门禁报错的情况下漏掉主题。由设计 token 驱动的皮肤应当归属于拥有这些 token 的包。
|
||||
|
||||
**提供一个工具类，由各滚动容器自行加上。** 重复同样被消除，但失败方式依旧存在：新的滚动容器只有在作者记得加类名时才有主题，而遗漏在评审中看不出来。`body, body *` 这种写法没有需要记住的启用步骤；确实想要不同滚动条的容器可以覆盖间接变量，这与抬升表面使用的机制相同。
|
||||
|
||||
**把这两个属性绑定在 `html` 上。** 这是文档级皮肤最自然的落点，而它的失败是可测量的：规则挂在 `html` 上时，chromium 中滚动容器计算出的 `scrollbar-color` 为 `auto`，因为别名 token 在那个作用域内不存在。
|
||||
|
||||
**只声明一次，靠继承下传。** 匹配的元素更少，但它破坏重新绑定契约——继承携带的是代入后的颜色，而不是变量引用，因此抬升表面无法给自己的滚动条换色。它本身也不完整，因为 `scrollbar-width` 不继承。
|
||||
|
||||
**不加 `@supports` 门禁，无条件同时声明标准属性与伪元素。** 这正是本次变更最初提交的形态，被评审发现。在 chromium 中于带 `scrollbar-gutter: stable`（使条带可观测）的探针元素上实测：单独一条 8px 的 `::-webkit-scrollbar` 预留出 30px 条带（样式表指定的宽度加上浏览器自带的按钮），而给同一元素加上 `scrollbar-width: thin` 后降到 `thin` 所预留的 10px——说明伪元素规则是被丢弃，而不是被合并。全部 `::-webkit-scrollbar-thumb:hover` 规则随之失效，因此两个 hover token 与四处抬升表面的 hover 重新绑定，在多数用户实际使用的引擎上都是死代码。
|
||||
|
||||
**给 WebKit 规则也加门禁，写成 `@supports selector(::-webkit-scrollbar)`。** 读起来对称，但在一个方向上是错的：它会对「实现了伪元素但不支持 `selector()`」的引擎隐藏这些规则，而那正是不加门禁时能被正确服务的 16.4 之前的 Safari。未知选择器本就会被丢弃，因此这道门禁不提供任何能抵偿该代价的保护。
|
||||
|
||||
**改用内边距而不是预留空位（给 `.list` 加右内边距，或把 `.time` 向内移）。** 之所以否决：内边距无论滚动条是否存在都生效，因此在常见的短列表情形下白白占用横向空间；而且它只修好一个容器，其余每个滚动区域的内容仍然压在滚动条之下。
|
||||
|
||||
**给 `.list` 用 `scrollbar-gutter: auto`。** 空位在列表溢出时出现，也就是滚动条存在的时候。之所以否决：侧边栏的列表会随分组展开与收起而伸缩，因此空位会在用户光标之下出现又消失，并带动行一起位移。
|
||||
|
||||
## 后果
|
||||
|
||||
- 客户端的每个滚动容器都绘制带主题的滑块：亮色基础表面为 `rgb(229, 229, 229)`，暗色基础表面为 `rgb(60, 60, 61)`，重新绑定到 l2 的暗色抬升表面为 `rgb(84, 85, 87)`。
|
||||
- 两种渲染分别指定，因此改动滑块的几何或 hover 行为需要改两处：一处在 `scrollbar-width`／`scrollbar-color`，一处在伪元素。让两者都经由这组间接变量，把这份重复限制在 Firefox 与 WebKit 不共用的那些属性上。
|
||||
- hover token（`--dsw-alias-scrollbar-hover-l1`／`-l2`）只在伪元素路径上渲染。Firefox 通过 `scrollbar-color` 只表述一个滑块颜色，其 hover 表现由引擎自行推导，因此对 hover 颜色的设计改动在 Chromium 与 Safari 上可见，在 Firefox 上不可见。这是 `scrollbar-color` 本身的限制，不是这张样式表的限制。
|
||||
- `body *` 匹配所有元素，涉及的两个属性其效果本就被浏览器限制在实际会滚动的元素上。代价是一个覆盖面很宽的选择器；另一种选择是一个不生效的重新绑定契约。
|
||||
- 工作区列表在任何列表长度下都永久少了预留空位那一条宽度。这正是该修复换来的代价：以稳定的行几何，换掉只在列表较短时才可读的时间戳。
|
||||
- 调色板中没有轨道 token，因此日后若设计需要不透明轨道，要新增一个别名 token，而不是在这张样式表里写字面颜色。
|
||||
|
||||
## 测试
|
||||
|
||||
三份单元测试读取磁盘上的 CSS 文本。`ui-theme/tests/scrollbar-styles.spec.ts` 从 `design-platform.css` 中扫描出滚动条 token 集合，而不是把它写死，因此新增、重命名或删除 token 时断言会随之变化；它检查每个 token 都有消费方，且每处抬升表面重新绑定的都是完整的一对。它还以源码偏移量锁定两条路径的划分：标准属性在门禁块之内，`::-webkit-scrollbar*` 规则与每一处对 hover 间接变量的读取都在门禁块之外。这个划分必须用偏移量断言，因为该测试文件的规则解析器会把 at-rule 拉平，所以删掉门禁或把某条声明移到门禁另一侧，文件里其余全部断言仍然是绿的。
|
||||
|
||||
`apps/web/tests/sidebar-scrollbar.e2e.ts` 覆盖只有真实渲染引擎才能报告的事实：预留条带的宽度，以及引擎实际走的是哪条渲染路径。它不需要任何模型调用——列表只要溢出即可——因此以只读方式复用一份既有的已提交 fixture（测试前置数据）来铺入冷会话。
|
||||
|
||||
这个场景还提交了一份 golden（期望产物）`snapshots/sidebar-scrollbar/geometry.expected.md`，记录两套调色板下解析后的滚动条样式与几何。其余 web 场景提交的 aria golden 承载不了纯 CSS 的改动：它不改变任何 DOM、也不改变任何无障碍名称，因此有无这次改动，它们规范化后的树都是逐字节相同的。改为记录解析后的取值，就让滑块颜色、条带宽度或渲染路径的意外变化成为可评审的 diff，而不是一条需要人去推敲的阈值断言。绝对坐标被特意排除——`timeRight` 与两条边缘取决于侧边栏排版后的宽度和字体度量，把它们提交进去会得到一份需要按平台重新录制的 fixture，那记录的是平台而不是这次改动。真正记录下来的是条带、重叠量与两个先后关系，每一项都是差值或比较，因此只要预留仍然成立，任何排版下都不变。
|
||||
|
||||
在构建产物客户端上于 headless chromium 中读取计算值确认，这正是区分「token 链真正生效」与「语法合法」的手段：滚动容器在两套调色板下分别计算出 l1 的滑块颜色，而重新绑定间接变量的容器计算出 l2 的颜色，证明重新绑定作用到了计算值，而不只是作用到自定义属性上。Firefox 的标准属性路径以同样方式做了验证，包含 `scrollbar-color` 上从 l1 到 l2 的重新绑定；headless Firefox 对任何元素（无论是否被样式命中）都报告 `scrollbar-width: none`，这是 headless 的产物，不是这张样式表造成的。
|
||||
|
||||
chromium 上有两处测量限制决定了 e2e 能断言什么。门禁使 chromium 报告的 `scrollbar-width` 与 `scrollbar-color` 都是 `auto`，因此代入后的 `scrollbar-color` 不再是可观测量——e2e 特意断言这个 `auto` 读数，因为此处出现具体值就意味着门禁泄漏、伪元素被静音。另外，`getComputedStyle(el, '::-webkit-scrollbar-thumb')` 会把 `::-webkit-scrollbar-thumb:hover` 规则一并折算进去，因此它在静止态就报告 hover 颜色，两种状态都锁不住；这一点由在运行中的页面里用 `CSSStyleSheet.deleteRule` 删掉 hover 规则得证——同一查询随之从 hover 颜色翻转为静止态颜色。因此 e2e 改为读取那组间接变量在列表上代入后的静止态与 hover 颜色（每个变量用一个一次性探针元素，因为 `getComputedStyle` 返回的是活的声明对象，复用探针只会报告最后一次读到的值），并把 hover 声明当作规则文本从层叠中读出。
|
||||
|
||||
门禁本身在它起作用的层面有反向对照：把样式表中的 `@supports` 包裹去掉、重新 `build:web`、再跑 e2e，`scrollbar-width: auto` 那条断言会以 `thin` 变红，而这正是门禁存在所要阻止的那种静音。
|
||||
|
||||
headless chromium 绘制的是覆盖式滚动条，而这恰好就是被报告症状存在的那种形态，因此这个 e2e 复现的是这个 bug 本身，而不是它的近似：在干净的 master 上，列表条带为 0，滚动条盖住相对时间 7px。其中预留空位不会缩小 `clientWidth`，因此把时间元素右边缘与内容区右边缘做比较的断言在有无预留的两种状态下都成立，它的通过或失败取决于平台的滚动条样式，而不是取决于被测的那条声明。真正能区分两种状态的两个量是 `offsetWidth - clientWidth` 条带，以及以滚动条自身宽度为基准量出的重叠量 `timeCoveredBy`。
|
||||
|
||||
两者都要断言，因为各自捕捉的是不同的回归；这一点通过每次只改动一条声明、并把同一个测试里的其余断言静音来确定。只删掉空位声明时 `timeCoveredBy` 仍为 0——此时滚动条是 8px，而行的右内边距也是 8px，于是它紧贴时间戳但并未盖住——失败的是条带那条断言。再把伪元素宽度也删掉（这才是 master 的真实状态）才会产生重叠，此时 `timeCoveredBy` 以 7 变红。在 xvfb 下的有头运行无论哪种状态都看不到这个症状，因为 chromium 在那里画的是经典占位滚动条，`clientWidth` 本来就已经把它排除了。
|
||||
|
||||
验证浏览器可见的插件 CSS 需要一次 `pnpm run build:web` 并不执行的重建。`WorkspaceBrowser.module.css` 从不进入 `apps/web/dist`：ui-workspace 以运行时插件方式加载，其 CSS 内联进 `packages/client/ui-workspace/lib/client.js`，由该包自己的 `bundle` 脚本构建。因此只重跑 `build:web` 的反向对照实际测的是旧产物，去掉声明后仍会通过，看起来像测试无效，实际是对照无效。正确做法是先 `pnpm --filter @deepseek-ai/dsh-client-ui-workspace run bundle`，用 grep 在 `lib/client.js` 中确认该声明确实存在或消失，然后再 `build:web`。
|
||||
|
||||
`test:web` 原先只运行 `build:web`，因此任何滚动区域或插件 CSS 的改动都会碰到这个陷阱；现在它先运行 `build`，而 `build` 覆盖 `packages/*/*`，从而会重建各插件产物。`check-all` 本来就把 `build` 排在 `build:web` 之前，所以 CI 从未受影响——受影响的只有本地脚本，而这恰恰是「产物过期却通过」最容易被当真的地方。

# Agent Note: Isolate pnpm setup per GitHub Actions runner
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-29-pnpm-setup-runner-isolation.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
`pnpm/action-setup@v4` defaults its install destination to `~/setup-pnpm` and replaces that directory during setup. The self-hosted CI failover runs six GitHub Actions runner services under one VM user, so concurrent jobs shared the same destination. In [run 30375670773](https://github.com/deepseek-harness/deepseek-harness/actions/runs/30375670773), three jobs entered pnpm setup within 73 milliseconds; one setup removed another process's current working directory and two jobs failed in Node's `uv_cwd` initialization. A retry on another runner passed, making the failure timing-dependent rather than a repository-test regression.
|
||||
|
||||
## Decision
|
||||
|
||||
Every `pnpm/action-setup` step in [the primary CI workflow](../../../../.github/workflows/ci.yml) sets `dest: ${{ runner.temp }}/setup-pnpm`. Each runner service owns its temporary directory, so one setup cannot replace another runner's install directory. Persistent store reuse remains separate through `PNPM_CONFIG_STORE_DIR`, as established by the [pnpm provisioning decision](../process/2026-07-26-pnpm-action-setup-for-symmetric-ci-caching.md).
|
||||
|
||||
[The workflow regression test](../../../../scripts/ci-workflow.spec.ts) discovers every `pnpm/action-setup` step in `ci.yml` and rejects one without the runner-private destination. This keeps newly added jobs inside the same isolation boundary.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Serialize failover jobs.** Rejected because it discards the six-runner pool's intended parallelism and turns an action-local directory collision into queueing across otherwise independent jobs.
|
||||
|
||||
**Assign a separate Unix user to every runner service.** This would also separate `HOME`, but it moves the invariant into external VM provisioning and complicates ownership of the deliberately shared persistent pnpm store. The workflow already receives a runner-private temporary directory.
|
||||
|
||||
**Retry failed setup steps.** Rejected because retries only reduce the observed collision rate; another concurrent setup can remove the same shared directory again.
|
||||
|
||||
## Consequences
|
||||
|
||||
pnpm's executable installation is ephemeral and isolated per runner, while package downloads still use the configured persistent or cached store. Hosted jobs use the same explicit destination without changing cache policy. The workflow carries three extra configuration lines per setup step, and the regression test must be updated only if pnpm provisioning intentionally moves to a different isolation mechanism.

# Agent Note: 按 GitHub Actions runner 隔离 pnpm 设置
|
||||
|
||||
Status: implemented
|
||||
|
||||
[English](2026-07-29-pnpm-setup-runner-isolation.md) | 中文
|
||||
|
||||
## 问题
|
||||
|
||||
`pnpm/action-setup@v4` 的安装目标目录默认为 `~/setup-pnpm`，并会在设置期间替换该目录。自托管 CI 故障切换在同一个 VM 用户下运行六个 GitHub Actions runner 服务，因此并发作业会共用同一目标目录。在 [run 30375670773](https://github.com/deepseek-harness/deepseek-harness/actions/runs/30375670773) 中，三个作业在 73 毫秒内进入 pnpm 设置；其中一个设置过程删除了另一个进程的当前工作目录，导致两个作业在 Node 的 `uv_cwd` 初始化阶段失败。换到另一台 runner 重试后通过，说明该故障取决于时序，并非仓库测试回归。
|
||||
|
||||
## 决策
|
||||
|
||||
[主 CI 工作流](../../../../.github/workflows/ci.yml)中的每个 `pnpm/action-setup` 步骤都设置 `dest: ${{ runner.temp }}/setup-pnpm`。每个 runner 服务独占自己的临时目录，因此一个设置过程无法替换另一个 runner 的安装目录。持久 store 的复用仍由 `PNPM_CONFIG_STORE_DIR` 独立处理，遵循 [pnpm 提供机制决策](../process/2026-07-26-pnpm-action-setup-for-symmetric-ci-caching.md)。
|
||||
|
||||
[工作流回归测试](../../../../scripts/ci-workflow.spec.ts)会找出 `ci.yml` 中的每个 `pnpm/action-setup` 步骤，并拒绝缺少 runner 专属目标目录的步骤。这可确保后续新增的作业也处于同一隔离边界内。
|
||||
|
||||
## 曾考虑的替代方案
|
||||
|
||||
**串行执行故障切换作业。** 否决：这会牺牲由六个 runner 组成的池所具备的预期并行能力，并把 action 内部的目录冲突变成原本相互独立作业之间的队列等待。
|
||||
|
||||
**为每个 runner 服务分配独立的 Unix 用户。** 这同样能够隔离 `HOME`，但会把该不变量转移到外部 VM 配置中，并使刻意共享的持久 pnpm store 的所有权变得复杂。工作流已经获得 runner 专属临时目录。
|
||||
|
||||
**重试失败的设置步骤。** 否决：重试只能降低观测到的冲突发生率；另一个并发设置过程仍可能再次删除同一个共享目录。
|
||||
|
||||
## 后果
|
||||
|
||||
pnpm 可执行文件采用临时安装，并按 runner 隔离；包下载仍使用已配置的持久或缓存 store。托管作业使用相同的显式目标目录，不改变缓存政策。工作流中的每个设置步骤因此增加三行配置；只有在 pnpm 提供机制有意迁移到另一种隔离机制时，才需要更新回归测试。

# Agent Note: Web details follow the current Session lifecycle
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-29-web-details-session-lifecycle.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The details entry is Session-scoped, but its preferred grid width is root-scoped. Selecting a different Session replaced the details content without closing that root preference, so the new owner inherited stale viewing geometry. Hero and other unselected states render no Session-scoped details; they need a derived zero track without becoming false owners in the comparison.
|
||||
|
||||
## Decision
|
||||
|
||||
`AppFrame` reads the current Session id and its `blank` summary flag from the authoritative Session projection. It records the last non-blank selected id only when that Session can own details, so hero and other unselected states neither trigger closure nor replace the last Session owner; their rendered details track derives as zero without changing the stored preference. The first Session keeps the default details width; returning to the same Session restores its current width; selecting a different Session closes the root-scoped details preference through the layout store before paint. The per-Session chat selection remains owned by the session-scoped store described by the [slot system standard](../architecture/2026-07-22-slot-type-chain-implementation.md).
|
||||
|
||||
The layout store is transient and starts details at its default width. It neither reads nor writes `localStorage`, so reload resets both panel widths and needs no Session-baseline exception. Manual close and reopen inside one unchanged Session retain their existing behavior. The lifecycle effect changes neither the [Workspace-owned New Session flow](../feature/2026-07-25-workspace-ui-product-flow.md), composer drafts, Session navigation, nor concession-chain resizing.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Close details in the New Session click handler.** Rejected because an unselected surface has no Session-scoped details and must not mutate geometry. Closure belongs to the later comparison between two defined Session owners.
|
||||
|
||||
**Persist panel geometry per Session.** Rejected because the product contract needs stale context removed, not a new map of remembered widths. Per-Session geometry would also reopen details when users return, contrary to the chosen close-on-leave behavior.
|
||||
|
||||
**Preserve persisted layout after the Session baseline is ready.** Rejected because it duplicates startup lifecycle in a presentation component solely to validate stale viewing state. Transient defaults make reload deterministic without a readiness flag.
|
||||
|
||||
**Treat every current-projection change as a Session switch.** Rejected because startup materialization, hero, clearing selection, and invalidation are not transitions between two Session owners.
|
||||
|
||||
## Consequences
|
||||
|
||||
Details is open by default, including when the first Session materializes. Switching to a different Session forgets the dragged details width because close writes zero and reopen uses the contract default.

# Agent Note: Web 详情栏遵循当前会话生命周期
|
||||
|
||||
Status: implemented
|
||||
|
||||
[English](2026-07-29-web-details-session-lifecycle.md) | 中文
|
||||
|
||||
## 问题
|
||||
|
||||
详情入口由会话作用域拥有，而其首选网格宽度由根作用域拥有。选择不同会话时，系统会替换详情内容，却不会关闭根作用域的该首选宽度，因此新 owner 会继承陈旧的查看几何信息。hero 和其他未选中状态不会渲染会话作用域的详情；其轨道需派生为零宽度，但不能因此在比较中成为伪 owner。
|
||||
|
||||
## 决策
|
||||
|
||||
`AppFrame` 从权威会话投影读取当前会话 id 及其摘要中的 `blank` 标志。它只在该会话能够拥有详情时记录最后一个选中的非 blank 会话 id，因此 hero 和其他未选中状态既不会触发关闭，也不会替换最后一个会话 owner；这些状态下，详情栏轨道的渲染宽度派生为零，但存储的首选宽度不变。首个会话保留详情栏的默认宽度；返回同一会话时恢复其当前宽度；选择不同会话时，系统会先通过布局 store 关闭根作用域存储的详情栏首选宽度，再进行绘制。逐会话的聊天选中项继续由 [slot 体系标准](../architecture/2026-07-22-slot-type-chain-implementation.md)所述的会话作用域 store 拥有。
|
||||
|
||||
布局 store 是瞬时状态，详情栏以默认宽度启动。它既不读取也不写入 `localStorage`，因此重新加载会重置两个面板的宽度，无需会话基线例外。在同一个未变化的会话内手动关闭和重新打开详情栏，仍保持原有行为。该生命周期 effect 不改变 [Workspace 拥有的 New Session 动线](../feature/2026-07-25-workspace-ui-product-flow.md)、composer 草稿、会话导航或让步链缩放。
|
||||
|
||||
## 考虑过的替代方案
|
||||
|
||||
**在 New Session 点击处理器中关闭详情栏。** 之所以否决：未选中表面没有会话作用域的详情，不得修改几何信息。详情栏是否关闭，应由随后对两个已定义会话 owner 的比较决定。
|
||||
|
||||
**按会话持久化面板几何信息。** 之所以否决：产品契约需要移除陈旧上下文，而不是新增一张保存各宽度的映射。按会话保存几何信息还会在用户返回时重新打开详情栏，与选定的离开即关闭行为相悖。
|
||||
|
||||
**在会话基线就绪后保留持久化布局。** 之所以否决：这会仅为验证陈旧的查看状态，在呈现组件中重复实现启动生命周期。瞬时默认值无需就绪标志即可使重新加载具有确定性。
|
||||
|
||||
**将当前投影的每次变化都视为会话切换。** 之所以否决：启动时的物化、hero、清除选中项和选中状态失效都不是两个会话 owner 之间的过渡。
|
||||
|
||||
## 后果
|
||||
|
||||
详情栏默认打开，首次会话物化时亦然。切换到不同会话会忘记拖动后的详情宽度，因为关闭操作会写入零值，重新打开时则使用契约默认值。未选中状态会将轨道的渲染宽度派生为零，同时保持首选几何信息不变；经由这些状态返回同一会话时，会恢复其宽度。重新加载会忘记侧边栏与详情栏的几何信息。布局行为测试覆盖初始默认值、首次物化、直接及经 hero 中转的会话切换、返回同一会话，以及不存在布局存储的情况；无密钥浏览器 e2e 则通过已交付的组合驱动相同的 owner 过渡，同时检查完整网格轨道和浏览器错误。

- **What does `policy: 'never'` actually change at runtime?** The service resolves every ask for that session to `rejected` before dispatching any answerer (in-service, so no registration order can bypass it); the system prompt states the policy; switches are narrated at boundaries; each successful auto-rejection records the audit pair.
|
||||
- **What happens across a hot reload, or when an answerer unloads mid-session?** Answerers dispose with their owning fiber, so the next ask degrades to `unavailable` instead of hanging on a dead channel; remounting re-registers the answerer with no catch-up state.

`@deepseek-ai/dsh-session-reference` is one context consumer service at `ctx.sessionReferences`. Hosts normalize their protocol into `SessionReferenceInput[]` and call `prepare()` before delivery. The service returns detached readable content plus an optional identified, frozen `UserMessage` snapshot; core agent packages do not parse session URIs or read another log.
|
||||
|
||||
`dsh-session:<base64url(JSON.stringify(sessionId))>` is the canonical host-independent identifier. JSON string encoding precedes base64url so quotes, slashes, backslashes, Unicode, newlines, and every other JavaScript string value round-trip without delimiter ambiguity. TUI renders that URI inside `@[label](uri)`; text-only clients may use the same inline mention. Explicit Markdown mentions reject malformed URIs. Bare text becomes a reference only for a non-empty base64url-shaped payload, whose decode must still be canonical; empty or punctuation-only uses remain ordinary discussion text.

`dsh-session:<base64url(JSON.stringify(sessionId))>` 是与宿主无关的规范标识符。系统先执行 JSON 字符串编码，再执行 base64url 编码，因此引号、正斜杠、反斜杠、Unicode、换行符以及其他任意 JavaScript 字符串值都能无损往返，不会因分隔符产生歧义。TUI 把该 URI 渲染到 `@[label](uri)` 中；纯文本客户端可以使用同一种行内提及标记。显式 Markdown 提及标记会拒绝格式错误的 URI。裸文本只有在负载非空且形状符合 base64url 时才会成为引用，而且解码过程仍须通过规范性校验；空负载或只含标点符号的用法仍按普通讨论文本处理。

# Agent Note: Docked web goal bar
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-22-docked-web-goal-bar.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The web UI had no goal surface at all: the goal stack shipped with model tools, the TUI/ACP adapters, and the `/goal` command, but the browser client exposed none of it — no runtime verbs, no indicator. This change introduces the client goal verbs (runtime session methods over RPC) and the first goal UI together. Placement follows the redesign's premise that goal presence belongs to the composer's context: the goal is a property of the work the user is about to prompt, so its indicator docks directly above the message composer as a rounded-top strip tucked under the composer card's top edge. The mock keeps only a sparkle, a phase word ("Ongoing/Paused/Blocked Goal"), the truncated objective, and edit/clear icon actions, with resume appearing only on a paused goal.
|
||||
|
||||
## Decision
|
||||
|
||||
`GoalBar` (`packages/client/ui-goal/src/client/GoalBar.tsx`) is a new props-driven, self-contained component; `ConversationRoot` mounts it immediately before the composer `InputBar`. The strip's CSS mirrors the composer's horizontal geometry (32px side padding, 776px centered cap) plus the mock's 12px inset, and a -10px bottom margin eats InputBar's 8px top padding and tucks its square bottom edge 2px under the composer card's top edge. All strip states share one fixed 38px height so switching between them never resizes it. Loading (`goal === undefined`), absent (`goal === null`), and `phase === 'complete'` render nothing — a completed goal is history, not chrome.
|
||||
|
||||
Visibility drives the label and actions: active shows "Ongoing Goal" with edit/clear; paused shows "Paused Goal" and adds a resume icon button; blocked shows "Blocked Goal" and carries `blockedReason.message` as the strip's `title` tooltip. Goal creation lives on the `/goal` command, not in the bar. The pencil swaps the strip for an inline edit form prefilled with the current objective: Enter or the check button saves through `GoalBarActions.onEdit(objective)`, Esc cancels, and an all-whitespace objective keeps save disabled. The form closes only when the edit succeeds; a failure preserves the draft and displays the error in the bar. Resume and clear failures are displayed there as well. Clear otherwise calls `onClear` directly with no confirmation — a clear keeps a durable tombstone, so nothing is unrecoverable. An effect keyed on the goal's id drops the edit form when the goal's identity changes, so a surviving draft can never be written over the goal that replaced it.
|
||||
|
||||
`GoalBarActions` lives in the contract layer (`contract/slots.ts`, next to the `ConversationInjected.goalActions` slot it feeds) and carries exactly the rendered verbs: `onEdit`/`onResume`/`onClear`. Each callback asynchronously returns an explicit success/failure result so `GoalBar` owns its transitions and error display. `apply.ts` wires them to the runtime session methods; the runtime session resolves the current goal's compare-and-set ref internally, so the UI passes no ref.
|
||||
|
||||
The runtime session gains the goal surface the strip (and future UI) needs: `fetchGoal` populates the snapshot on open, and a live `context/message` carrying `goal/change` meta triggers a coalesced refetch — concurrent triggers share the in-flight `goal.get`, while a trigger received during that read schedules one coalesced trailing read so independently ordered notifications and GET responses cannot leave stale state. Window replays never refetch, and matching the meta kind (rather than a goal key) also catches clear tombstones written by other clients. The six mutation verbs fold transport failures into `{ ok: false }` results like every sibling session method, and a get result older than a mutation response that landed mid-flight is dropped.
|
||||
|
||||
The strip's background is `--dsw-alias-interactive-bg-hover` rather than the mock's literal `#F5F6F7`: the translucent hover gray resolves to that value over the white light-theme base and lifts the strip off the composer card in dark mode, where a static light token would sink. All colors are `--dsw-*` tokens.
|
||||
|
||||
## Testing
|
||||
|
||||
`packages/client/ui-goal/tests/goalbar.spec.tsx` pins the behavior through props alone: loading/absent/complete render nothing, the active strip renders label/objective and fires clear, the edit form prefills, rejects empty, saves on Enter, cancels on Esc, and resets when the goal's identity changes, the paused strip fires resume, and the blocked strip exposes the reason tooltip. Component failure-path cases prove that a failed edit preserves its draft and that edit/resume/clear errors remain visible in the bar. The skeleton specs mount `ConversationRoot` with and without `goalActions`; the undefined case is seeded with an active goal, so the missing gate — not the missing goal — is what hides the strip. Runtime session specs pin the folded-error results, the live-only in-flight-plus-trailing refetch, and the stale-read guard. A keyless real-browser smoke boots the assembled application through `boot → RPC → runtime → GoalBar` and records an inline snapshot of the rendered label, objective, and actions.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
- **Put the strip in the session header** — rejected because the redesign's premise is that goal presence belongs to the composer's context; a header strip cannot dock into the composer card.
|
||||
- **Render a "Loading goal…" placeholder for `undefined`** — rejected: the strip would flash and collapse on every session open, chrome noise for a sub-second state.
|
||||
- **Include an inline create affordance when no goal is set** — rejected after implementation review: goal creation lives on the `/goal` command, matching the pattern where the model creates goals on request; the bar is a status indicator, not a creation surface.
|
||||
- **Carry the full verb set (`onPause`/`onComplete`) in `GoalBarActions`** — rejected as speculative generality: no consumer calls them, so the interface carries only the rendered verbs.
|
||||
|
||||
## Consequences
|
||||
|
||||
- Goal presence in the web UI is a composer-docked strip: sparkle, phase label, truncated objective, and edit/clear (plus resume when paused) — the browser client's first goal surface.
|
||||
- The runtime session exposes the goal verbs over RPC with folded transport errors, and refreshes the snapshot's goal on open and on live goal-change meta (coalesced, guarded against stale reads).
|
||||
- Objective editing is reachable from the UI for the first time, through `goal.edit` with the runtime-owned ref; pause/complete remain available to other surfaces (`/goal`, model tools).
|
||||
- `goal === null` renders nothing; the composer carries no persistent create affordance — creation is the `/goal` command's job.

# Agent Note: 停靠式 Web 目标条
|
||||
|

Status: implemented

||||
|
||||
## 问题
|
||||
|
||||
Web UI 此前没有任何目标相关的界面：目标栈已随模型工具、TUI/ACP 适配器和 `/goal` 命令交付，但浏览器客户端完全不接触它——既没有运行时动词，也没有指示器。本变更同时引入客户端目标动词（基于 RPC 的运行时会话方法）和第一个目标 UI。摆放位置遵循重新设计的前提：目标的存在感属于输入框的上下文——目标是用户即将提交的工作的属性，因此它的指示器停靠在消息输入框正上方，呈现为一条圆角顶部的横条，收进输入框卡片顶边之下。设计稿只保留一个闪光图标、一个阶段词（"Ongoing/Paused/Blocked Goal"）、截断后的目标内容，以及编辑／清除图标操作，恢复按钮仅在目标暂停时出现。
|
||||
|
||||
## 决策
|
||||
|
||||
`GoalBar`（`packages/client/ui-goal/src/client/GoalBar.tsx`）是一个新的、由 props 驱动的自包含组件；`ConversationRoot` 将它挂载在输入框 `InputBar` 紧上方。横条的 CSS 对齐输入框的水平几何（两侧 32px 内边距、776px 居中上限），再加上设计稿的 12px 内缩，并用 -10px 的下外边距吃掉 InputBar 的 8px 上内边距，使它方形的底边收进输入框卡片顶边之下 2px。横条的所有状态共享固定的 38px 高度，状态切换不会引起尺寸变化。加载中（`goal === undefined`）、无目标（`goal === null`）和 `phase === 'complete'` 时不渲染任何内容：已完成的目标是历史记录，不是常驻界面元素。
|
||||
|
||||
可见性决定标签和操作：active 状态显示 "Ongoing Goal" 并提供编辑／清除；paused 状态显示 "Paused Goal"，并增加一个恢复图标按钮；blocked 状态显示 "Blocked Goal"，并把 `blockedReason.message` 作为横条的 `title` 悬浮提示。创建目标的入口在 `/goal` 命令上，不在横条里。铅笔图标把横条切换为内联编辑表单，预填当前目标内容：Enter 或勾选按钮通过 `GoalBarActions.onEdit(objective)` 保存，Esc 取消，目标内容全为空白字符时保存按钮保持禁用。编辑成功后表单才会关闭；编辑失败时保留草稿，并在横条中显示错误。恢复和清除失败也显示在横条中。除此之外，清除直接调用 `onClear`，不做确认——清除会保留 durable 墓碑，没有不可恢复的损失。一个以目标 id 为键的 effect 会在目标身份变化时丢弃编辑表单，因此存留的草稿绝不可能覆盖掉替换它的新目标。
|
||||
|
||||
`GoalBarActions` 位于 contract 层（`contract/slots.ts`，紧挨它所喂给的 `ConversationInjected.goalActions` 槽位），只携带实际渲染的动词：`onEdit`/`onResume`/`onClear`。每个回调都会异步返回显式成功／失败结果，因此 `GoalBar` 自行负责界面转换和错误显示。`apply.ts` 把它们接到运行时会话方法上；运行时会话在内部解析当前目标的 compare-and-set ref，因此 UI 不传 ref。
|
||||
|
||||
运行时会话获得了横条（以及未来 UI）所需的目标表面：`fetchGoal` 在打开时填充快照；携带 `goal/change` 元数据的 live `context/message` 触发合并重新拉取——并发触发器共享正在执行的 `goal.get`，读取期间收到的触发器会安排一次合并后的尾随读取，避免彼此独立排序的通知和 GET 响应留下陈旧状态。窗口重放绝不触发重新拉取，且匹配元数据 kind（而不是 goal 键）还能捕获其他客户端写入的清除墓碑。六个变更动词与所有同类会话方法一样，把传输层失败折叠为 `{ ok: false }` 结果；比在拉取途中落地的变更响应更旧的 get 结果会被丢弃。
|
||||
|
||||
横条的背景色用 `--dsw-alias-interactive-bg-hover`，而不是设计稿里的字面值 `#F5F6F7`：这个半透明的悬浮灰在浅色主题的白色底上正好解析为该值，而在深色模式下能把横条从输入框卡片上衬托出来，静态的浅色 token 在深色模式下会沉进去。所有颜色都是 `--dsw-*` token。
|
||||
|
||||
## 测试
|
||||
|
||||
`packages/client/ui-goal/tests/goalbar.spec.tsx` 仅通过 props 固定这些行为：加载中／无目标／已完成时不渲染；active 横条渲染标签和目标内容并触发清除；编辑表单预填内容、拒绝空值、按 Enter 保存、按 Esc 取消，并在目标身份变化时重置；paused 横条触发恢复；blocked 横条暴露原因悬浮提示。组件失败路径用例证明编辑失败时保留草稿，并且编辑／恢复／清除错误持续显示在横条中。skeleton 规格测试分别挂载带与不带 `goalActions` 的 `ConversationRoot`；未定义的情形预置了一个 active 目标，因此隐藏横条的是缺失的挂载门，而不是缺失的目标。运行时会话规格测试固定了折叠错误结果、仅 live 的执行中读取加尾随读取，以及陈旧读取守卫。一个无密钥真实浏览器冒烟测试通过 `boot → RPC → runtime → GoalBar` 启动组装后的应用，并以内联快照记录渲染出的标签、目标内容和操作。
|
||||
|
||||
## 考虑过的替代方案
|
||||
|
||||
- **把横条放在会话头部**：不予采纳，因为重新设计的前提是目标的存在感属于输入框的上下文；放在头部的横条无法停靠进输入框卡片。
|
||||
- **为 `undefined` 渲染 "Loading goal…" 占位**：不予采纳，每次打开会话横条都会闪现再坍缩，对一个不到一秒的状态来说只是界面噪音。
|
||||
- **未设置目标时在横条内提供内联创建入口**：实现评审后不予采纳，创建目标的职责在 `/goal` 命令上，与模型按请求创建目标的模式一致；横条是状态指示器，不是创建入口。
|
||||
- **在 `GoalBarActions` 中携带完整动词集合（`onPause`/`onComplete`）**：作为投机性泛化不予采纳，没有消费方调用它们，接口只携带实际渲染的动词。
|
||||
|
||||
## 后果
|
||||
|
||||
- Web UI 中目标的存在形式是停靠在输入框上方的横条：闪光图标、阶段标签、截断的目标内容，以及编辑／清除（暂停时另有恢复）——这是浏览器客户端的第一个目标界面。
|
||||
- 运行时会话通过 RPC 暴露目标动词并折叠传输层错误，且在打开时和 live 目标变更元数据到达时刷新快照中的目标（合并拉取，带陈旧读取守卫）。
|
||||
- 目标内容首次可以从 UI 编辑，经由 `goal.edit`，ref 由运行时持有；暂停／完成对其他界面（`/goal`、模型工具）照常可用。
|
||||
- `goal === null` 时不渲染任何内容；输入框不提供常驻的创建入口，创建是 `/goal` 命令的职责。

# Agent Note: Web UI permission presets and approval answering
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-23-web-permission-and-approval.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The web host booted an unconfined agent: `bootHost` composed `dsh-bash-local` and `dsh-fs-local`, so every web session ran with full file access, no approval channel, and no permission control — while the ACP composition had shipped the complete sandboxed product path (sandbox provider + policy home + confined bash/fs + approval + presets) for months. The web wire contract had already reserved the seats — `approval/requested`/`approval/resolved` mux frames, `POST /api/respond` with `ApprovalResponsePayload`, client-side `pendingBuffers` — but the host `respond` was a stub, no answerer bridged `ctx.approval` to the stream, no RPC exposed the permission select, and the PendingCard rendered approvals as visible-but-unanswerable.
|
||||
|
||||
## Decision
|
||||
|
||||
The web host composes the same sandboxed product path as the acp-agent composition: `dsh-sandbox-local`, `dsh-sandbox-policy`, `dsh-bash-sandbox`, `dsh-fs-sandbox`, `dsh-user-approval`, and `dsh-permission`, with `BootHostOptions.sandbox` supplying the deployment defaults (`mode`, default `workspace-write`; `approvalPolicy`, default `ask`).
|
||||
|
||||
`createApiProxy` owns the approval pending registry. Its `approval/request` waterfall answerer reads the approval id from the session's just-appended `approval/asked` audit event (an ask with no audit event is a foreign channel and delegates), mints one stable rpcId per question, broadcasts the answerable `approval/requested` frame to every open mux stream, and replays still-pending frames verbatim on each mux open — the refresh-recovery baseline the contract already promised. `respond` routes by the echoed rpcId, validates `ApprovalResponsePayload` with the existing zod schema, cross-checks the payload's audit correlation against the routed entry, resolves the answerer, and broadcasts `approval/resolved`; the ask's abort signal withdraws the question as `cancelled`.
|
||||
|
||||
The permission select rides two new unary RPCs, `session.permissions` and `session.setPermission`, projecting `ctx.permission` into a protocol-owned `PermissionOption` DTO (the ACP bridge precedent: each protocol owns its presentation shape). A permission-less composition serves an empty select and clients hide the control. Idle switches are held last-write-wins in a proxy-side pending map and flushed on `agent/prompt-submit`, because knob events must stay turn-enclosed for durable replay; the shared `hasOpenTurn` fold moved to `dsh-session` and replaced the private copies in `dsh-user-approval`, the ACP bridge, and the proxy.
|
||||
|
||||
Client-side, `Session` gained `permissions` and `setPermission`, and approval answering rides the runtime's `PendingWait` carrier. Per the designer draft, a pending approval takes over the composer: `ApprovalPanel` registers as a selector-routed entry of the conversation-declared `conversation.composer` chain (the ui-question pattern), replacing the InputBar with the justification headline, the paired command, and one-shot refuse/allow buttons; the `PendingApproval` domain face in ui-conversation's contract owns the `ApprovalResponsePayload` wire encoding over the carrier, and the broadcast resolved frame settles the wait and restores the composer. Question placeholders stay in the message flow. The sidebar mirrors the blocked state with an amber warning dot that outranks the running ring: the manager tracks per-session outstanding approvalIds (idempotent under mux-open replays, cleared per connection generation so the reopen replay is authoritative) rather than reading Session instances, so the dot lights for sessions never instantiated. The composer's bottom-row chip hosts the `PermissionSelect` control fed through the conversation inject face. The connection fixture mirrors the host: its resident approval is answerable once, and its permission select persists per session.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Reuse the ACP `session/set_config_option` shape on the web wire.** Rejected: the web contract's unary method registry (`RpcMethodMap` + per-method zod schemas) is its own dialect; a generic config-option surface would bypass the compiler-locked schema table for one select. A dedicated method pair keeps both sides derivable from the signature.
|
||||
|
||||
**A session event for pending approvals instead of a proxy-side registry.** Rejected: approval requests are transient interaction state, not durable session data — the `approval/asked`/`decided` audit pair already logs the durable half. Persisting requested frames would re-ask dead questions on replay.
|
||||
|
||||
**Registering the answerer only when a mux subscriber exists.** Rejected: the pending entry must survive client disconnects (refresh recovery is the point), so the registry outlives any one stream; a subscriber-gated answerer would fail asks closed during a reload window.
|
||||
|
||||
**Optimistic card removal on click.** Rejected: the broadcast resolved frame is the truth; removing on click would hide a question that a rejected receipt or transport failure left standing. The panel disables its buttons locally and re-arms them on failure instead.
|
||||
|
||||
## Consequences
|
||||
|
||||
Web sessions now start confined (`workspace-write` + `ask` by default) and a sandbox-denial escalation reaches the browser as an answerable card; the deployment can widen or narrow the default through `BootHostOptions.sandbox` without touching the assembly. Question answering shipped separately through the same registry pattern (ui-question over the question pending table). The permission select reads once per mount; live refresh from another client's switch is deferred. Coverage: proxy registry and permission RPC unit suites, session-object and fixture unit suites, and the keyless web smoke exercises the fixture-mode approval answer and preset switch in a real browser.

# Agent Note: Web UI 权限预设与审批应答
|
||||

|
||||
## 问题
|
||||
|
||||
Web 承载层启动的是一个不受限的 agent（智能体）：`bootHost` 组合了 `dsh-bash-local` 与 `dsh-fs-local`，因此每个 Web 会话都以完整文件访问权限运行，既无审批通道，也无权限管控——而 ACP 组合早在数月前就已交付完整的沙箱化产品路径（沙箱提供方 + 策略归属 + 受限的 bash/fs + 审批 + 预设）。Web 协议契约其实早已预留了对应位置——`approval/requested`/`approval/resolved` 的 mux 帧、携带 `ApprovalResponsePayload` 的 `POST /api/respond`、client 侧的 `pendingBuffers`——但 host 的 `respond` 只是一个 stub，没有应答者把 `ctx.approval` 桥接到流上，没有 RPC 暴露权限选择，PendingCard 把审批渲染成可见却无法应答的样子。
|
||||
|
||||
## 决策
|
||||
|
||||
Web 承载层组合与 acp-agent 相同的沙箱化产品路径：`dsh-sandbox-local`、`dsh-sandbox-policy`、`dsh-bash-sandbox`、`dsh-fs-sandbox`、`dsh-user-approval` 与 `dsh-permission`，由 `BootHostOptions.sandbox` 提供部署默认值（`mode`，默认 `workspace-write`；`approvalPolicy`，默认 `ask`）。
|
||||
|
||||
`createApiProxy` 拥有审批 pending 注册表。它的 `approval/request` waterfall（瀑布式事件）应答者从会话刚追加的 `approval/asked` 审计事件中读取审批 id（没有审计事件的 ask 属于外部通道，予以委托），为每个问题 mint 一个稳定的 rpcId，向每个打开的 mux 流广播可应答的 `approval/requested` 帧，并在每次 mux 打开时原样重放仍处于 pending 的帧——这正是契约早已承诺的刷新恢复基线。`respond` 按回显的 rpcId 路由，用既有的 zod schema 校验 `ApprovalResponsePayload`，将载荷的审计关联与所路由的条目交叉核对，解析应答者，并广播 `approval/resolved`；ask 的中断信号会以 `cancelled` 撤回该问题。
|
||||
|
||||
权限选择依托两个新的一元 RPC，`session.permissions` 与 `session.setPermission`，把 `ctx.permission` 投影为一个由协议拥有的 `PermissionOption` DTO（沿用 ACP bridge 的先例：每个协议拥有自己的呈现形状）。无权限的组合提供空的选择项，client 隐藏该控件。空闲期的切换以后写胜出（last-write-wins）的方式保存在 proxy 侧的 pending map 中，并在 `agent/prompt-submit` 时冲刷，因为旋钮事件必须保持轮次内闭合以支持持久回放；共享的 `hasOpenTurn` 折叠迁入 `dsh-session`，取代了 `dsh-user-approval`、ACP bridge 与 proxy 中各自的私有副本。
|
||||
|
||||
在 client 侧，`Session` 新增了 `permissions` 与 `setPermission`，审批应答则依托运行时的 `PendingWait` 载体。按照设计师草稿，处于 pending 的审批会接管 composer：`ApprovalPanel` 注册为由会话声明的 `conversation.composer` 链中一个按选择器路由的条目（即 ui-question 模式），以理由标题、配对的命令与一次性的拒绝／允许按钮取代 InputBar；ui-conversation 契约中的 `PendingApproval` 领域面拥有 `ApprovalResponsePayload` 在该载体上的协议编码（wire encoding），广播的 resolved 帧使该等待落定并恢复 composer。问题占位符仍留在消息流中。侧边栏用一枚琥珀色警示圆点同步呈现这一阻塞状态，且其优先级高于表示运行中的圆环：manager 跟踪每个会话尚未解决的 approvalId（对 mux 打开时的回放幂等，并按连接代次清除，以保证重开后的回放才是权威依据），而非读取 Session 实例，因此从未实例化过的会话也能点亮该圆点。composer 底行的 chip 经会话注入面挂载 `PermissionSelect` 控件。连接 fixture（测试前置数据）与 host 保持一致：它的常驻审批可应答一次，其权限选择项按会话持久保存。
|
||||
|
||||
## 曾考虑的替代方案
|
||||
|
||||
**在 Web 协议上复用 ACP 的 `session/set_config_option` 形状。** 不予采纳：Web 契约的一元方法注册表（`RpcMethodMap` + 逐方法的 zod schema）是它自成一体的方言；一个通用的 config-option 接口会为一个选择项绕开编译期锁定的 schema 表。一对专用方法让两侧都能从签名推导得出。
|
||||
|
||||
**用一个会话事件承载 pending 审批，而非 proxy 侧注册表。** 不予采纳：审批请求是瞬态的交互状态，而非持久的会话数据——`approval/asked`/`decided` 审计对已经记录了持久的那一半。持久化 requested 帧会在回放时重新问出已经作废的问题。
|
||||
|
||||
**仅在存在 mux 订阅者时才注册应答者。** 不予采纳：pending 条目必须在 client 断连后依然存活（刷新恢复正是要点所在），因此注册表的生命周期长于任何单个流；一个受订阅者门控的应答者，会让在重载窗口期间关闭的 ask 落空。

||||

`applyEventSideEffects` gains a `todo/write` case (whole list, last write wins). Unlike partial/openCalls, `rebuildDerivedFromWindow` deliberately does NOT reset it: the value is session-level — taken from the tail history page's full-log projection — and an arbitrary window may not contain the latest write, so an older-page prepend keeps it and only an in-window or live write overwrites it. Every `installWindow` caller is a tail request (`doOpen`, its gap re-pull, `repairGap`; `loadOlder` prepends without it), which the host answers with the projection or omits it only when the full log holds no `todo/write` — so an absent field is the authoritative empty list and is assigned as such. That distinction matters on rollback: a live write whose host crashed before persisting leaves the log empty, and preserving the prior value instead would strand the rolled-back plan on screen indefinitely. `ConversationSnapshot.todos` is the read surface. This follows the event's own contract ("log-only UI state; never derived history"): surfacing each write as a conversation node would render superseded lists as if they were still standing.

# Agent Note: In-process subagent policy inheritance — the child starts under the parent's sandbox and approval overrides
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-25-subagent-policy-inheritance.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
Sandbox and approval overrides are per-session log folds. An in-process subagent gets a new session, so a spawn child once fell back to deployment defaults and a fork child saw only switches inside its completed-turn prefix. Delegation could therefore widen a parent that had switched to `read-only`, or turn a parent's unattended `'never'` approval stance back into prompting behavior.
|
||||
|
||||
## Decision
|
||||
|
||||
The shared in-process driver snapshots `sandboxPolicy.overrideOf(parent.session)` and `approval.overrideOf(parent.session)` before its first await. A later parent switch belongs to the parent's future; cancel-and-redelegate takes a new snapshot. Both services are optional, and only explicit session overrides are copied, never deployment defaults or one-shot grants.
|
||||
|
||||
Each captured value becomes a source-tagged `sandbox/mode` or `approval/policy` event appended during the child factory's unpublished setup. The session constructor has already fixed `Session.firstLiveSeq` at the fork-prefix length, so the inherited facts follow fork history, reach telemetry when the child is announced, and leave `SessionHeader.seedLength` at the prefix length. Existing last-event-wins folds therefore make the delegation snapshot beat stale fork history and let a later child switch beat the snapshot. A grandchild folds its parent's logged state, so the rule composes without another inheritance mechanism.
|
||||
|
||||
Ordinary session appends validate the inherited events before publication, and persistence captures the complete unpublished log when the session is announced. Any materialized child log therefore stores the inherited events with its first batch; there is no second policy store, schema field, or query index. The `source: 'delegation'` marker lets approval narration distinguish inheritance from a child-side user switch.
|
||||
|
||||
### What a blocked child experiences
|
||||
|
||||
A confined child gets the ordinary denial marker. No answerer currently owns an in-process child, so an escalation request fails closed and the child reports upward; a controller-owned parent may widen its own session and delegate again. An inherited `'never'` policy tells the child not to request escalation in its first system prompt.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
- **Generic `SessionHeader` policy fields** — rejected: they duplicate an event-sourced fact in metadata and require propagation through core session types, persistence backends, query indexes, collision identity, and every policy consumer. Unpublished setup events have the required ordering and reuse the existing durable store.
|
||||
- **Combining new policy facts with constructor history** — rejected: `Session.firstLiveSeq` classifies the complete constructor seed as replayed history, so telemetry would skip child-only facts. Unpublished setup keeps history and new facts on their existing sides of that boundary without another session option.
|
||||
- **A first-prompt listener** — rejected: it introduces listener ordering and a later timing boundary even though the creation transaction already permits log appends before publication.
|
||||
- **Copying deployment defaults** — rejected: defaults remain operator-owned and may change; an unswitched parent stamps nothing, so its child follows the current deployment.
|
||||
- **Live resolution walking `parentSession` at each call** — rejected: it breaks the "two sessions never see each other's state" isolation invariant, requires the parent session to stay loaded for the child's lifetime, and makes a mid-run parent switch retroactively change a running child. Snapshot-at-delegation is the semantic: the child keeps the policy it was handed; cancel-and-respawn picks up a tightening.
|
||||
- **Forcing `'never'` or routing asks to the root controller** — rejected as inheritance behavior. A forced value forecloses a future child answerer; parent routing needs parent-chain ownership and the spawning `callId`, and remains deferred in [the approval-seam Agent Note](2026-07-06-approval-seam.md).
|
||||
|
||||
## Consequences
|
||||
|
||||
- Spawn, fork, and nested in-process children retain a parent's explicit sandbox and approval overrides. The focused suite proves real filesystem denial, stale-fork precedence, delegation-time capture, the live-event boundary, default omission, and context disposal.
|
||||
- The keyless headless snapshot is the assembled regression: only the parent is `read-only`, the deployment default is `workspace-write`, and the child's persisted event plus denied disk write both fail if capture is removed.
|
||||
- Each delegation adds at most two log-only events. `dsh-subagent-inprocess` has optional peer types for the two policy services; compositions without either service behave unchanged. Out-of-process children retain their own deployment policy, and a running child does not follow later parent switches.

# Agent Note: 进程内 subagent 策略继承——子 agent 在父级的沙箱与审批覆盖项下启动
|
||||
|
||||
Status: implemented
|
||||
|
||||
[English](2026-07-25-subagent-policy-inheritance.md) | 中文
|
||||
|
||||
## 问题
|
||||
|
||||
沙箱与审批覆盖项都是按会话的日志折叠。进程内 subagent 会获得一个新会话，因此 spawn 子 agent（智能体）过去会回退到部署默认值，fork 子 agent 则只能看到其已完成轮次前缀中的切换。因此，委派可能放宽已经切换到 `read-only` 的父级，或让父级无人值守的 `'never'` 审批立场重新变成会发起提示的行为。
|
||||
|
||||
## 决策
|
||||
|
||||
共享的进程内驱动器在第一次 await 之前对 `sandboxPolicy.overrideOf(parent.session)` 和 `approval.overrideOf(parent.session)` 获取快照。父级后续的切换属于父级的未来；取消后重新委派会取得新快照。这两个服务均为可选，仅复制显式会话覆盖项，绝不复制部署默认值或一次性授权。
|
||||
|
||||
每个捕获值都会成为子 agent 工厂在未发布设置阶段追加的一条带来源标记的 `sandbox/mode` 或 `approval/policy` 事件。会话构造函数已将 `Session.firstLiveSeq` 固定为 fork 前缀的长度，因此继承事实会排在 fork 历史之后，在子 agent 公布时进入遥测，同时让 `SessionHeader.seedLength` 保持为此前缀的长度。因此，既有的末事件胜出折叠会让委派快照压过陈旧的 fork 历史，并让子 agent 后续的切换压过该快照。孙代 agent 会折叠其父级已记录的状态，因此无需另一套继承机制即可组合此规则。
|
||||
|
||||
普通的会话追加会在发布前校验继承事件，持久化层则在会话公布时捕获完整的未发布日志。因此，任何已物化的子 agent 日志都会在首批数据中存下继承事件；不存在第二套策略存储、schema 字段或查询索引。`source: 'delegation'` 标记让审批叙述能够区分继承与子 agent 侧的用户切换。
|
||||
|
||||
### 被拦住的子 agent 会经历什么
|
||||
|
||||
受限子 agent 会得到普通拒绝标记。目前没有应答器认领进程内子 agent，因此升级请求会失败关闭，由子 agent 向上汇报；由控制器持有的父 agent 可以放宽自己的会话后重新委派。继承的 `'never'` 策略会在第一份系统提示词中告知子 agent 不要请求升级。
|
||||
|
||||
## 考虑过的替代方案
|
||||
|
||||
- **通用的 `SessionHeader` 策略字段**：不予采纳。它们会在元数据中复制一项事件溯源事实，并要求贯穿核心会话类型、持久化后端、查询索引、碰撞标识与每个策略消费方进行传播。未发布设置阶段的事件具备所需顺序，并复用现有持久化存储。
|
||||
- **将新策略事实与构造历史合并**：不予采纳。`Session.firstLiveSeq` 会把完整的构造种子归类为回放历史，因此遥测会跳过仅属于子 agent 的事实。未发布设置让历史与新事实留在该边界各自原有的一侧，无需再增加会话选项。
|
||||
- **首个提示词监听器**：不予采纳。尽管创建事务已经允许在发布前追加日志，它仍会引入监听器顺序与更晚的时序边界。
|
||||
- **复制部署默认值**：不予采纳。默认值仍由运维人员拥有且可能变化；未切换的父级不会盖章写入任何内容，因此其子 agent 跟随当前部署。
|
||||
- **每次调用时沿 `parentSession` 实时解析**：不予采纳。这会打破「两个会话永远看不到彼此状态」的隔离不变量，要求父会话在子 agent 的整个生命周期内保持加载，还会让父级在子 agent 运行途中做的切换追溯性地改变一个正在运行的子 agent。委派时快照才是本设计的语义：子 agent 保持它被交付时的策略；取消后重新 spawn 即可拿到收紧后的策略。
|
||||
- **强制使用 `'never'` 或把 ask 路由到根控制器**：不作为继承行为采纳。强制值会排除未来的子 agent 应答器；父级路由需要父链所有权与发起 spawn 的 `callId`，仍按[审批 seam Agent Note](2026-07-06-approval-seam.md) 所述延期。
|
||||
|
||||
## 后果
|
||||
|
||||
- spawn、fork 和嵌套的进程内子 agent 会保留父级显式的沙箱与审批覆盖项。聚焦测试套件证明真实文件系统拒绝、陈旧 fork 优先级、委派时捕获、实时事件边界、默认值省略与上下文释放。
|
||||
- 无密钥 headless 快照是组装后应用层面的回归测试：只有父级是 `read-only`，部署默认值是 `workspace-write`；若移除捕获，子 agent 的持久化事件与被拒的磁盘写入这两项检查都会失败。
|
||||
- 每次委派最多增加两条仅日志事件。`dsh-subagent-inprocess` 为两个策略服务提供可选 peer 类型；未组合任一服务的组合保持原有行为。进程外子 agent 仍采用自身的部署策略，正在运行的子 agent 不跟随父级后续切换。

# Agent Note: SDK max output tokens
|

Status: implemented
|

English | [中文](2026-07-28-sdk-max-output-tokens.zh.md)

|
||||
## Problem
|
||||
|
||||
The Python and TypeScript SDKs could select a provider and model but could not bound conversation-model output. The runtime therefore omitted `GenerateOptions.maxTokens`, leaving provider defaults in control even when an evaluation host required a fixed output budget. `compact-basic.maxTokens` could not fill this role because it limits only compaction-summary calls.
|
||||
|
||||
## Decision
|
||||
|
||||
The high-level SDKs expose one optional process-wide output cap: Python names it `max_tokens`, TypeScript names it `maxTokens`, and the shared `initialize` wire payload carries `maxTokens`. The JSON-RPC server rejects values that are not positive safe integers and stores the accepted cap with its provider/model route.
|
||||
|
||||
Each SDK-created root Agent receives the cap through `AgentOptions.maxTokens`. Agent Loop places that value in the initial `LlmCallConfig`, logs it in the request header, and reconstructs every dispatched conversation request from that durable header. Omitting the option leaves `maxTokens` absent so the selected provider retains its default.
|
||||
|
||||
In-process subagents inherit the parent's provider, model, and output cap. An explicit `SubagentStartRequest.agentOptions.maxTokens`, including one configured by `dsh-tool-subagent`, overrides the inherited value for that child and its descendants. Out-of-process providers own the configuration of their separate runtime; `subagent-dsh-sdk` therefore exposes its own optional `maxTokens` and forwards it through that child runtime's SDK handshake.
|
||||
|
||||
Compaction, session-title generation, web search, and other auxiliary calls keep their independently owned output limits. `maxTokensAsSuccess` remains outcome mapping only: it does not set or alter the cap.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Set an adapter environment variable.** This would be DeepSeek-adapter-specific, invisible in the session request header, ineffective for intercepted or alternate adapters, and easy to confuse with a provider default. The cap belongs in provider-neutral request configuration.
|
||||
|
||||
**Add `maxTokens` to every `session/prompt`.** Per-turn mutation would enlarge the wire and introduce request-config transitions that callers do not need for the current evaluation use case. A runtime initialization option gives every session in one SDK process the same reproducible budget.
|
||||
|
||||
**Reuse `compact-basic.maxTokens`.** The compaction value controls summary generation, not ordinary conversation requests. Sharing it would couple two different token budgets and make tuning one silently change the other.
|
||||
|
||||
## Consequences
|
||||
|
||||
SDK callers can bound model output without editing Cordis composition, and direct Agent creation uses the same validated `AgentOptions` contract. The cap is visible in durable request headers and reaches provider adapters as `GenerateOptions.maxTokens`; DeepSeek serialization maps it to `max_tokens`.
|
||||
|
||||
One SDK runtime has one default cap. A caller needing different caps runs separate runtime instances or explicitly overrides an in-process child through its agent options. Reaching the cap still produces the existing `max-tokens` stop reason, whose `ok` or `error` mapping remains deployment policy.

# Agent Note: SDK 最大输出 token

|
||||
|
||||
## Problem
|
||||
|
||||
Python 与 TypeScript SDK 可以选择提供方和模型，却无法限制对话模型输出。即使评测宿主要求固定输出预算，运行时仍会省略 `GenerateOptions.maxTokens`，由提供方默认值控制。`compact-basic.maxTokens` 只限制压缩摘要调用，不能承担这一职责。
|
||||
|
||||
## Decision
|
||||
|
||||
高层 SDK 公开一个可选的进程级输出上限：Python 命名为 `max_tokens`，TypeScript 命名为 `maxTokens`，共享的 `initialize` 线载荷使用 `maxTokens`。JSON-RPC 服务端拒绝非正安全整数，并将通过校验的上限与提供方／模型路由一同保存。
|
||||
|
||||
每个由 SDK 创建的根 Agent 都通过 `AgentOptions.maxTokens` 获得该上限。Agent Loop 将它放入初始 `LlmCallConfig`、记录到请求 header，并从该持久化 header 重建每次分派的对话请求。省略该选项时，`maxTokens` 保持缺失，由所选提供方保留默认值。
|
||||
|
||||
进程内 subagent 继承父级的提供方、模型和输出上限。显式的 `SubagentStartRequest.agentOptions.maxTokens`（包括通过 `dsh-tool-subagent` 配置的值）会覆盖该子级及其后代的继承值。进程外提供方自行持有其独立运行时的配置；因此 `subagent-dsh-sdk` 公开独立的可选 `maxTokens`，并通过该子运行时自己的 SDK 握手传入。
|
||||
|
||||
压缩、会话标题生成、网页搜索和其他辅助调用继续使用各自持有的独立输出上限。`maxTokensAsSuccess` 仍然只负责结果映射，不会设置或改变上限。

**设置适配器环境变量。** 这种方式仅适用于 DeepSeek 适配器，不会出现在会话请求 header 中，对被拦截请求或其他适配器无效，也容易与提供方默认值混淆。该上限属于提供方无关的请求配置。
|
||||
|
||||
**在每个 `session/prompt` 上增加 `maxTokens`。** 按轮次修改会扩大线协议，并引入当前评测用例不需要的请求配置转换。运行时初始化选项可让一个 SDK 进程中的每个会话拥有相同、可重现的预算。
|
||||
|
||||
**复用 `compact-basic.maxTokens`。** 压缩值控制摘要生成，而非普通对话请求。共用会耦合两类不同 token 预算，调整一方时会静默改变另一方。
|
||||
|
||||
## Consequences
|
||||
|
||||
SDK 调用方无需修改 Cordis 组合即可限制模型输出，直接创建 Agent 也使用同一套经过校验的 `AgentOptions` 契约。该上限在持久化请求 header 中可见，并以 `GenerateOptions.maxTokens` 到达提供方适配器；DeepSeek 序列化会将其映射为 `max_tokens`。
|
||||
|
||||
一个 SDK 运行时只有一个默认上限。需要不同上限的调用方应运行独立的 runtime 实例，或通过 agent options 显式覆盖某个进程内子级。达到上限时仍产生现有的 `max-tokens` 停止原因；将其映射为 `ok` 还是 `error` 仍由部署策略决定。

# Agent Note: Todo plan strip clears on the next turn
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-28-todo-plan-clears-on-next-turn.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
`todo_write` stores whole-list snapshots on the session log, and interactive hosts render the latest list as a plan strip (web TodoPanel via the `todos` projection, TUI Plan panel). After a turn finished, that strip stayed on screen into the next user turn — a completed or abandoned checklist from the previous task. Readers treat the strip as "what this turn is doing," so a stale list across the turn boundary is the wrong product lifetime. The [web todo display](2026-07-23-web-todo-display.md) and [`todo_write` tool](2026-06-29-todo-write-tool.md) notes still own event-sourcing and the two render surfaces; they described the standing plan as lasting for the whole session until the next write.
|
||||
|
||||
## Decision
|
||||
|
||||
The standing plan is the latest `todo/write` that is not followed by a later `turn/start`. `turn/end` keeps the list visible so the finished checklist remains while the user reads the answer; the next `turn/start` clears it until the model writes again.
|
||||
|
||||
### Host projection (web)
|
||||
|
||||
`dsh-tool-todo`'s `todos` projection unit folds the rule: `apply` takes the whole list from each `todo/write` and returns `null` on each `turn/start` (`stateVersion` 2). Carriers (`dsh-host-apiproxy`) serve that value on the history tail `projections` block and push `session/projection` frames; the web dock reads it through `useProjection('todos')`. The keyless fixture mirrors the same fold for assembled snapshots.
|
||||
|
||||
### TUI live path
|
||||
|
||||
The TUI `renderEvent` switch still clears its local plan panel on `turn/start` and replaces it on `todo/write` (TUI is not yet a projection carrier). The rebuild path resets the panel before replaying the log so cold resume converges on the same rule.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
- **Clear on `turn/end`** — hides the checklist while the user is still reading the just-finished answer; the strip's job at that moment is the completed plan, not an empty dock.
|
||||
- **Clear only when every item is `completed`** — leaves abandoned or partial plans across turns; the strip would still show another task's work.
|
||||
- **Append an empty `todo/write` on turn start** — mutates the log for a UI lifetime rule and invents a write the model never authored.
|
||||
|
||||
## Consequences
|
||||
|
||||
The host projection and the TUI panel share one lifetime rule; reopening a session restores a plan only when no later turn has started. Partial supersession of the session-long standing-plan wording in [web todo display](2026-07-23-web-todo-display.md) and [`todo_write` tool](2026-06-29-todo-write-tool.md): event-sourcing, last-write-wins replacement, and the two render surfaces stay there; this note owns turn-boundary clearance. Coverage: tool-todo projection specs for turn/start clear + turn/end keep, fixture push-frame clearance for the assembled web snapshot, plus the TUI snapshot that starts the next turn and pins the strip gone.

# Agent Note: 下一轮开始时清空 todo 计划条
|
||||
|
||||
Status: implemented
|
||||
|
||||
[English](2026-07-28-todo-plan-clears-on-next-turn.md) | 中文
|
||||
|
||||
## 问题
|
||||
|
||||
`todo_write` 在会话日志中存储整表快照，交互式宿主把最新列表渲染为计划条（web TodoPanel 经 `todos` 投影，TUI Plan 面板）。一轮结束后，该条仍留在下一用户轮次的屏幕上——上一任务已完成或已放弃的清单。读者把计划条理解为「本轮正在做什么」，因此跨轮次的陈旧列表是错误的产品生命周期。[web todo 展示](2026-07-23-web-todo-display.md)与 [`todo_write` 工具](2026-06-29-todo-write-tool.md)笔记仍拥有事件溯源与两个渲染面；它们把站立计划描述为持续整段会话直至下一次写入。
|
||||
|
||||
## 决策
|
||||
|
||||
站立计划是其后没有更晚 `turn/start` 的最近一次 `todo/write`。`turn/end` 保留列表可见，以便用户阅读回答时仍能看到刚完成的清单；下一次 `turn/start` 将其清空，直至模型再次写入。
|
||||
|
||||
### Host 投影（web）
|
||||
|
||||
`dsh-tool-todo` 的 `todos` 投影单元折叠该规则：`apply` 从每个 `todo/write` 取整表，并在每个 `turn/start` 返回 `null`（`stateVersion` 2）。载体（`dsh-host-apiproxy`）在历史尾页的 `projections` 块与 `session/projection` 推送帧上供给该值；web dock 经 `useProjection('todos')` 读取。无密钥 fixture（测试前置数据）镜像同一折叠，供组装后的 snapshot 使用。
|
||||
|
||||
### TUI 实时路径
|
||||
|
||||
TUI 的 `renderEvent` 分支仍在 `turn/start` 清空本地计划面板、在 `todo/write` 替换之（TUI 尚非投影载体）。重建路径在回放日志前重置面板，使冷恢复收敛到同一规则。
|
||||
|
||||
## 考虑过的替代方案
|
||||
|
||||
- **在 `turn/end` 清空**——用户仍在阅读刚完成的回答时就隐藏清单；此时计划条的职责是已完成计划，而非空 dock。
|
||||
- **仅在全部项为 `completed` 时清空**——会让放弃或部分完成的计划跨轮残留；计划条仍会显示另一任务的工作。
|
||||
- **在 turn start 追加空的 `todo/write`**——为 UI 生命周期规则改写日志，并捏造模型从未写出的写入。
|
||||
|
||||
## 后果
|
||||
|
||||
Host 投影与 TUI 面板共用同一生命周期规则；重新打开会话仅在其后没有更晚轮次开始时恢复计划。部分取代 [web todo 展示](2026-07-23-web-todo-display.md)与 [`todo_write` 工具](2026-06-29-todo-write-tool.md)中「会话级站立计划」的表述：事件溯源、last-write-wins 替换与两个渲染面仍归那些笔记；本笔记拥有轮次边界清空。覆盖：tool-todo 投影对 turn/start 清空与 turn/end 保留的规格测试、供组装 web snapshot 的 fixture 推送帧清空，以及启动下一轮并钉住计划条消失的 TUI snapshot。

# Agent Note: Tool-call file open in OS
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-28-tool-call-file-open-in-os.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
Chat tool rows treated the whole summary line as a click target that opened the right-hand details panel, with a hover background on the row. For filesystem tools the useful action is opening the mentioned file in the operating system's default application, not inspecting the raw tool payload in a sidebar.
|
||||
|
||||
## Decision
|
||||
|
||||
File-tool path summaries (`read` / `write` / `edit` args carrying `path` or `file_path`) render as hover-underline links with a pointer cursor. Clicking the path calls `host.openPath` through `WorkspacesService.openPath`, resolving relative paths against the session cwd. File-link rows disable args expand (leading icon is inert); whole-row click, row hover fill, and the click-to-open-details gesture are removed from tool rows (including bash and todo registrations). The details panel and its inject surface remain for programmatic selection; rows no longer drive them.
|
||||
|
||||
`host.openPath` is a privileged unary RPC accepted only from loopback, same-origin browser requests (same carrier guard as `host.pickDirectory`). Platform adapters open without a shell: `open` on macOS, PowerShell `Invoke-Item` on Windows, `xdg-open` on Linux. The opener is injectable for tests. URL-only read args (`web_fetch`) are not file links.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
- Keep row-click details and add a separate file affordance — rejected; the product ask replaces the row gesture with the file link.
|
||||
- Open files inside an in-app preview — rejected; the ask is the OS default application.
|
||||
- Reuse `host.pickDirectory`'s timeout exemption — unnecessary; path open hand-off completes quickly under the normal unary deadline.
|
||||
|
||||
## Consequences
|
||||
|
||||
Clicking a file path in a tool row opens that path on the host. Non-file tool rows are inert summaries (expand toggles remain where the row already supported them). Remote or non-loopback clients cannot invoke `host.openPath`.
|
||||
|
||||
## Risks
|
||||
|
||||
- Linux hosts without `xdg-open` fail the RPC; the chat row stays silent while the host returns an internal error.
|
||||
- Relative paths without a session cwd are forwarded verbatim and may fail on the host.

# Agent Note: 在工具调用中用系统应用打开文件
|
||||
|
||||
Status: implemented
|
||||
|
||||
[English](2026-07-28-tool-call-file-open-in-os.md) | 中文
|
||||
|
||||
## Problem
|
||||
|
||||
聊天工具行把整行摘要当作点击目标，点击后打开右侧 details 面板，并带有整行悬停背景。对文件系统工具而言，有用的动作是用操作系统默认应用打开所涉文件，而不是在侧栏里查看原始工具载荷。
|
||||
|
||||
## Decision
|
||||
|
||||
文件工具的路径摘要（`read`／`write`／`edit` 参数中的 `path` 或 `file_path`）渲染为悬停下划线链接并使用 pointer 光标。点击路径会经 `WorkspacesService.openPath` 调用 `host.openPath`，相对路径相对会话 cwd 解析。带文件链接的行关闭参数展开（左侧图标不可点）；工具行（含 bash 与 todo 注册）去掉整行点击、整行悬停底色，以及点击打开 details 的手势。details 面板及其 inject 面仍保留供程序化选择；工具行不再驱动它们。
|
||||
|
||||
`host.openPath` 是特权一元 RPC，仅接受来自回环、同源浏览器请求（与 `host.pickDirectory` 相同的载体守卫）。平台适配器不经 shell 打开：macOS 为 `open`，Windows 为 PowerShell `Invoke-Item`，Linux 为 `xdg-open`。打开器可在测试中注入。仅含 URL 的 read 参数（`web_fetch`）不是文件链接。
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
- 保留整行点击打开 details，另加文件入口 — 否决；产品要求用文件链接替换整行手势。
|
||||
- 在应用内预览文件 — 否决；要求是操作系统默认应用。
|
||||
- 复用 `host.pickDirectory` 的超时豁免 — 不必要；打开路径的交接在常规一元截止时间内即可完成。
|
||||
|
||||
## Consequences
|
||||
|
||||
点击工具行中的文件路径会在宿主上打开该路径。非文件工具行是惰性摘要（行内已有的展开开关仍保留）。远程或非回环客户端无法调用 `host.openPath`。
|
||||
|
||||
## Risks
|
||||
|
||||
- 没有 `xdg-open` 的 Linux 宿主会使 RPC 失败；聊天行保持静默，宿主返回 internal 错误。
|
||||
- 没有会话 cwd 时相对路径会原样转发，可能在宿主侧失败。

# Agent Note: Web message IconActions and clocks

|

Status: implemented
|
||||
|
||||
English | [中文](2026-07-29-web-message-icon-actions-and-clock.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The web chat user bubble already had copy / branch / edit IconActions but no clock. Finalized assistant narration had no under-body action chrome at all, even though the Harness design shows a copy / branch / clock row after the answer settles. Streaming replies must not flash that chrome mid-token. Memoized rows also keep stable props across midnight, so a one-shot `Date.now()` would leave yesterday's messages stuck on `HH:mm`.
|
||||
|
||||
## Decision
|
||||
|
||||
**User bubbles prepend a date-aware local clock to the existing IconActions row; finalized assistant nodes append a copy / branch / clock row with `margin-top: 16px`; both seats re-format at the next local midnight.**
|
||||
|
||||
Both seats format `node.time` through `formatMessageClock`: same calendar day → `HH:mm`, earlier this year → `M月D日 HH:mm`, other years → `YYYY年M月D日 HH:mm`. `useCalendarDay` is a component-local day tick (timeout to the next local midnight) so memoized rows re-render when the calendar day changes without a new framework hook. `MessageItem` places the label before copy (figma `388:20051`). `AssistantMarkdown` places it after branch (figma `43:32997`) and only when `streaming` is false with a known event time; the streaming tail omits the row. Copy writes joined text blocks. Branch stays a chrome stub. Hover-capable pointers keep both footers opacity-hidden until hover/focus-within. Clipboard write and the clock helpers live in `message-chrome.ts`. The assembled surface is pinned by `apps/web/tests/message-actions.e2e.ts` (cold-seeded history + aria golden); aria normalization collapses every clock shape to `{{clock}}`.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Show assistant IconActions during streaming.** Rejected: the request is to reveal the row only after output completes; mid-stream chrome would flicker and invite copying a partial answer.
|
||||
|
||||
**Wire branch to a real session fork.** Rejected for this change: same rationale as the archived [user IconActions note](../../archived/feature/2026-07-27-user-message-icon-actions.md) — the mutation path is unspecified; the button reserves the design seat.
|
||||
|
||||
**Publish the calendar day through a chat store or inject hook.** Rejected: the day tick is presentation-only local state with no cross-entry consumers; a component-local timeout matches the client rule that behavioral hooks may own state that does not subscribe to an external source.
|
||||
|
||||
## Consequences
|
||||
|
||||
Settled assistant answers expose copy and the event clock immediately; branch stays a stub. User and assistant clocks share the same day/year widening rules and refresh after midnight without a message mutation. Per-message paging remains a deferred footer seat in the package README. Package tests pin the three clock shapes and the midnight widen; the web e2e scenario pins the assembled IconActions chrome.

# Agent Note: Web 消息 IconActions 与时钟

[English](2026-07-29-web-message-icon-actions-and-clock.md) | 中文
|
||||
|
||||
## 问题
|
||||
|
||||
Web 聊天的用户气泡已有复制／分支／编辑 IconActions，但没有时钟。已定稿的 assistant 叙述下方完全没有操作栏，尽管 Harness 设计稿在回答结束后展示复制／分支／时钟。流式回复不得在 token 中途闪出该栏。经 memo 的行在跨午夜时仍保持稳定 props，因此一次性的 `Date.now()` 会让昨日消息一直卡在 `HH:mm`。
|
||||
|
||||
## 决策
|
||||
|
||||
**用户气泡在既有 IconActions 行前追加感知日期的本地时钟；已定稿的 assistant 节点在正文下追加带 `margin-top: 16px` 的复制／分支／时钟；两边都在下一个本地午夜重新格式化。**
|
||||
|
||||
两边都通过 `formatMessageClock` 格式化 `node.time`：同一日历日 → `HH:mm`，同年更早 → `M月D日 HH:mm`，跨年 → `YYYY年M月D日 HH:mm`。`useCalendarDay` 是组件本地的日刻度（定时到下一个本地午夜），因此 memo 行在日历日变化时会重渲染，且不新增框架 hook。`MessageItem` 把标签放在复制之前（figma `388:20051`）。`AssistantMarkdown` 把它放在分支之后（figma `43:32997`），且仅在 `streaming` 为 false 且已知事件时间时渲染；流式尾部省略该行。复制写入拼接后的 text 块。分支仍是 chrome stub。具备 hover 能力的指针在 hover／focus-within 前保持两条 footer 透明。剪贴板写入与时钟辅助函数放在 `message-chrome.ts`。组装面由 `apps/web/tests/message-actions.e2e.ts`（冷 seed 历史 + aria golden）钉住；aria 归一化把每种时钟形态折叠为 `{{clock}}`。
|
||||
|
||||
## 曾考虑的方案
|
||||
|
||||
**在流式过程中展示 assistant IconActions。** 否决：需求是输出完成后才展示该行；中途 chrome 会闪烁，并诱使复制半截回答。
|
||||
|
||||
**把分支接到真实的会话 fork。** 本次否决：与已归档的[用户 IconActions 笔记](../../archived/feature/2026-07-27-user-message-icon-actions.md)同一理由——变更路径尚未规定；按钮只预留设计座位。
|
||||
|
||||
**通过 chat store 或 inject hook 发布日历日。** 否决：日刻度只是展示层本地状态，没有跨入口消费者；组件本地 timeout 符合「行为 hook 可拥有不订阅外部源的状态」这一客户端规则。
|
||||
|
||||
## 后果
|
||||
|
||||
已定稿的 assistant 回答立刻暴露复制与事件时钟；分支仍为 stub。用户与 assistant 时钟共用同一套跨天／跨年加宽规则，并在午夜后无需消息变更即可刷新。逐消息分页仍是包 README 中的暂缓 footer 座位。包级测试钉住三种时钟形态与午夜加宽；Web e2e 场景钉住组装后的 IconActions chrome。

The repo shipped on **Yarn 4** with the `node-modules` linker — a deliberately conservative choice that behaves like npm's flat layout while giving us Yarn's workspaces and `yarn constraints`. It worked. But Yarn 4's Plug'n'Play heritage makes the `node-modules` linker the off-the-beaten-path mode, and the broader JS ecosystem — tooling defaults, CI actions, Corepack examples, contributor familiarity — increasingly centers on pnpm. For a repo that is built primarily by agents and read by occasional human contributors, "the package manager most tools and people expect" has real value: fewer surprises, better-trodden failure paths, more copy-pasteable answers.

The switching cost is at its lowest right now. Nothing publishes from this repo yet (every package is `private: true`); dev/test/demo all run **unbuilt** via tsx, so the package manager only has to (a) resolve and link `node_modules`, (b) run the workspace scripts, and (c) enforce the workspace constraints. The one Yarn-specific asset is `yarn.config.cjs` (the `@yarnpkg/types` constraints engine), which is small and mechanical to re-express. This mirrors the reasoning in [the tsdown decision](../../archived/process/2026-06-11-tsdown-over-dumble.md): swap a load-bearing tool for the healthier-ecosystem option while the blast radius is still small.

本仓库最初使用 **Yarn 4** 搭配 `node-modules` 链接器启动。这是一个刻意保守的选择：行为类似 npm 的扁平布局，同时享有 Yarn 的 workspaces 和 `yarn constraints`。它能正常工作。但 Yarn 4 源自 Plug'n'Play 的血统，使得 `node-modules` 链接器成为非主流模式；而更广泛的 JS 生态——工具默认值、CI action、Corepack 示例、贡献者的熟悉度——正日益以 pnpm 为中心。对于一个主要由 agent（智能体）构建、偶尔有人类贡献者阅读的仓库而言，「大多数工具和人所期望的包管理器」具有实际价值：更少的意外、更成熟的故障路径、更多可直接复用的解答。

Prompt text is scrubbed; one scenario per header class pins readable prompt and tool content as described in the [header-pinning Agent Note](../../archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md). Override scenarios derive model behavior solely from their sidecar.

2. The **re-persisted session JSONL**, normalized and compared with `session.jsonl`. The same fixture is both replay source and expected log. Prompt and tool bulk are scrubbed; one scenario per header class pins the remaining header sequence. The pin owns readable prompt and tool-schema sidecars by default, or names another pin as either source when the complete sequence is identical, so each distinct sidecar version is committed once. Fixture guards reject duplicate sidecar content, and record/refresh rejects shared claimants that generate different bytes. The original header-pinning rationale is preserved in the [header-pinning Agent Note](../../archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md). Override scenarios derive model behavior solely from their sidecar.

The surfaces are complementary: stdout covers the minimal automation wire, while JSONL covers loop, tool, and boundary structure that the wire intentionally omits.

Normalization replaces session, cwd, protocol-id, timestamp, path, and process volatility while preserving deterministic sequence numbers. Scenarios constrain real bash use to stable commands. The stdout expected output remains wire-shaped JSONL and every raw line must parse as JSON. Vitest updates only the stdout expected output; normalized session equality never overwrites the replay fixture.

Normalization replaces session, cwd, protocol-id, timestamp, path, and process volatility while preserving deterministic sequence numbers. Record and refresh also store a generated workspace and its filesystem-resolved aliases as `{{cwd}}` in the replay fixture, so platform temp roots and random basenames do not affect recordings; authored temp paths and cwd values under an explicit `workspaceParent` remain literal. Scenarios constrain real bash use to stable commands. The stdout expected output remains wire-shaped JSONL and every raw line must parse as JSON. Ordinary Vitest snapshot updates write only the stdout expected output; the explicit `record` and `refresh` modes own replay-fixture writes.

The tier adds reviewed per-scenario input, session, stdout, optional override, and optional workspace fixtures. Workspace seeds are copied into the generated cwd for both record and replay. In return the tier provides deterministic keyless coverage through the real Loader and tool composition. Most retained scenarios exercise the assembled backend rather than ACP; the [automation-only ACP decision](../simplification/2026-07-23-acp-automation-only-protocol.md#snapshot-boundary) keeps that corpus here and defers any move to a transport-neutral headless suite as an independent testing change (the suite-level FIXME marks it).

Most retained scenarios exercise the assembled backend rather than ACP; the [automation-only ACP decision](../simplification/2026-07-23-acp-automation-only-protocol.md#snapshot-boundary) keeps that corpus here and defers any move to a transport-neutral headless suite as an independent testing change (the suite-level FIXME marks it).

This Agent Note relates to but does not supersede the [proposed determinism Agent Note](../../proposed/testing/2026-06-11-deterministic-and-stress-testing.md): that proposal's "universal replay fixture" re-derives session *message history* after every test (an internal-consistency invariant), whereas these snapshots pin assembled behavior plus the external automation output. They are complementary until the backend corpus moves off ACP.

Live-turn scenarios pin ordinary tool execution, cancellation, non-retryable failure, transient retry, resident questions, and mid-turn steering; synchronization uses durable events, `whenIdle()`, or an explicit replay marker rather than delays. Cold-history scenarios seed through the real persistence API and cover history rendering, sidebar search, trajectory and waterfall views, and tool details without model calls. Browser-lifecycle scenarios cover first-send workspace materialization, reload recovery, layout persistence, theme and locale preferences, and workspace create/rename/view operations. Each family asserts the browser surface and the authoritative host state; a stray model call or under-consumed fixture fails teardown.

`@deepseek-ai/dsh-llm-mock-server` is a private support package with an importable Node HTTP server. The repository-local `pnpm run mock:llm` source entry provides a standalone process for manual fault injection; the package exposes no installable binary.

Script exhaustion fails loud; repetition requires `repeatLast`.

Request behaviors cover socket reset, post-header disconnect, partial disconnect, stall, valid empty completion, clean truncated streams, malformed payloads, representative HTTP failures, complete text/reasoning/tool-call responses, slow streaming, and max-token completion. A true `connection_refused` is a CLI listener-lifecycle phase because a bound request handler cannot refuse its own TCP connection.

**Use only an in-process `LlmAdapter` mock** — rejected because it bypasses fetch, HTTP status/header parsing, SSE framing, socket termination, and the adapter idle watchdog: the exact boundaries this test infrastructure exists to exercise.
|

|
||||
**Expose an installable workspace binary** — rejected because pnpm links dependency binaries before repository build outputs exist, coupling clean installs to a test-only artifact. The repository-local source command supports the same manual fault injection without adding a package installation surface.

**Change retry defaults with the server** — rejected because the server reveals existing semantics rather than deciding policy. Extending recovery to `STREAM_CLOSED` requires a separate decision with its own cost, latency, and duplicate-generation trade-offs.

## Consequences
|
||||
|
||||
Developers can reproduce fault sequences by changing only provider URL/key configuration, and automated tests can keep socket-level failures deterministic through explicit scripts and seeds. The same wire fixture now exposes gaps between hard resets, clean truncation, and recovered empty completions without splicing attempts or modifying model history.
|
||||
|
||||
The server adds a support package, executable build entry, and behavior vocabulary that must remain compatible with both direct tests and CLI examples. Arrival-ordered scripts are intentionally shared across clients, random defaults are stress weights rather than operational truth, and exact connection refusal requires coordinating the client attempt with the pre-listen interval.
