+# Agent Note: Web transcript marks context source, recall, and steering
+
+Status: implemented
+
+English | [中文](2026-08-04-web-context-source-and-steer-marks.zh.md)
+
+## Problem
+
+Everything a producer adds to the model-facing conversation reached the Web transcript as one of two anonymous shapes. Every logged non-user `user/message` — the skill catalog, the runtime snapshot, reconciled `AGENTS.md` instructions, a guard notice, a subagent report, a cross-session snapshot — collapsed into one identical `上下文注入` row, so a reader could not tell what had been added without expanding each row and reading raw JSON. Mid-turn steering was worse: it rendered in exactly the bubble a turn-opening prompt uses, leaving the transcript unable to say which message interrupted a running turn.
+
+The distinctions are already durable. `user/message.source` is the merge-extensible provenance every producer must supply, while `agent/inbox/spliced` records whether an identified message entered and left `next-turn` or `next-step`; only the presentation discarded them. The terminal transcript this Web UI replaced did name each card's producer, so the Web surface was a regression for the same log.
+
+## Decision
+
+The transcript names all three roles a non-prompt message can play — injected context, recalled session, and steering.
+
+`TranscriptAdapter` and the history fold attach a `provenance` view to every `ContextMessageNode`, computed by `contextProvenance()` from the durable source alone. It returns a `role` (`inject`, or `recall` for a cross-session snapshot) and a `label` naming the producer. `ContextInjectionRow` titles itself from the role and shows the label beside that title in `ToolRow`'s summary geometry, so the collapsed row already answers what was added and by whom; the 141px scrollport and truncation bound are unchanged from the [disclosure decision](2026-07-30-web-context-injection-disclosure.md). What renders inside that scrollport is chosen by the independent form axis added in the [context form decision](2026-08-05-context-form-vocabulary.md).
+
+**The label is read out of the log, never from a client-side table of producer names.** `workspace-instructions` is named by the distinct instruction paths it reconciled, `session-reference` by the titles of the sessions it read, a plugin source by its logged plugin id, and any other source by its own `kind` — the documented default arm for a merge-extensible union. A source carrying no readable kind degrades to an unnamed injection. A new or renamed producer is therefore identifiable without a client release, no label can go stale against the code, and a resumed, forked, or foreign log projects exactly like a live session.
+
+`recall` covers `session-reference` because that is the one shipped source that lifts another session's material into this one. No Web leaf mounts `dsh-session-reference` today — it had only a terminal host — so the arm exists for log portability rather than for a bundled producer, and it is exercised by unit coverage rather than an assembled Web scenario.
+
+`MessageItem` captions durable and pending steering bubbles with `插话`. The runtime replays durable `agent/inbox/spliced` events and projects a user-origin `user/message` as `SteeringMessageNode` when that same message identity was claimed from `next-step`; a queued-turn claim stays a `UserMessageNode`, and a non-user next-step message stays context. This reverses one clause of [no steer entry or interjection chrome](../simplification/2026-07-31-web-ui-no-steer-entry-or-interjection-chrome.md), which removed the badge because the composer could not steer and the label named a gesture users could not perform. The composer gained a Steer gesture afterwards without amending that note; this decision supplies the product decision its reintroduction clause required, and corrects the stale facts left in it. The caption is the only steering chrome here: composer modes, the Queue dock's strict-steer action, and pending-steering lifecycle stay with their own owners.
+
+## Alternatives considered
+
+**Localize producer names in the client.** A dictionary keyed by plugin id would read better than `@deepseek-ai/dsh-system-prompt`, but it drifts silently on every rename, needs a client change per new producer, and cannot name a producer from a foreign log at all. Provenance the log already carries is worth more than prose the client invents.
+
+**Register presentations per source kind.** The disclosure decision deferred a keyed context-view slot until source-owned presentations emerged. Naming a row is not a distinct presentation, and a registry keyed on mounted producers would fail exactly where it matters — a resumed log whose producer is no longer mounted still has to render.
+
+**Compute the role and label on the host.** The host would have to attach a view to each event copy, duplicating what the durable source already states and adding a wire field per context message. The projection derives it once per node instead, where the transcript's other derived facts live.
+
+**Give steering its own row instead of a captioned bubble.** Steering is a user message that arrived mid-turn; a separate row shape would break the right-aligned reading rhythm and duplicate the bubble's copy and branch actions for no new information.
+
+**Extend the trajectory table with the same names.** Out of scope: the table's context cell has its own text derivation, and the issue asks for the conversation surface.
+
+## Testing
+
+- `packages/client/runtime` unit coverage pins each provenance arm, the label fallbacks when a name field is missing, empty, or wrongly typed, the unnamed degradation for a source with no readable kind, and steering reconstruction on reset and live append paths.
+- `packages/client/ui-conversation` jsdom coverage pins the role title, the producer label beside it, the label's survival while expanded, the roleless header, and the steering caption on both durable and pending bubbles.
+- The keyless assembled-Web goldens carry the named header and the steering caption, so the assembled transcript — not only component tests — proves the marks.
+
+## Consequences
+
+- A reader can attribute every non-prompt message in the transcript at a glance, and the header stays honest for logs this client version has never seen a producer for.
+- Producer names in the UI are package-shaped (`dsh-tool-skill`, `@deepseek-ai/dsh-system-prompt`) wherever the source carries only a plugin id. That is the cost of refusing a client-side name table; a producer that wants a better name records better provenance.
+- `ContextMessageNode` gains a required field, so every constructed node — including test fixtures — must supply it.
+- `SteeringMessageNode` remains a distinct presentation node even though the agent loop now records admitted steering as `user/message`; its identity comes from the durable inbox history rather than a separate message event.
+- The `recall` arm has no producer in a shipped Web leaf until a host mounts `dsh-session-reference`; it is reachable only through logs written elsewhere.

+# Agent Note：Web transcript 标出上下文来源、召回与 steering
+
+Status: implemented
+
+[English](2026-08-04-web-context-source-and-steer-marks.md) | 中文
+
+## Problem
+
+生产方向模型侧对话补充的一切内容，进入 Web transcript（文本记录）后只剩两种匿名形态。每一条已记录的非用户 `user/message`——skill 目录、运行时快照、经过对账的 `AGENTS.md` 指令、guard 提示、子 agent 汇报、跨会话快照——都塌缩成同一行 `上下文注入`，读者不逐行展开去读原始 JSON 就无从知道究竟注入了什么。steering（中途引导）的情况更糟：它渲染成与开轮提示完全相同的气泡，于是 transcript 无法说明哪一条消息打断了正在运行的轮次。
+
+这些区分本来就是持久事实。`user/message.source` 是每个生产方都必须提供的可合并扩展来源，`agent/inbox/spliced` 则记录有身份的消息是从 `next-turn` 还是 `next-step` 进入和离开；把这些事实丢掉的只有呈现层。被这套 Web UI 取代的终端 transcript 本来会写出每张卡片的生产者，因此面对同一份日志，Web 侧是一次倒退。
+
+## Decision
+
+transcript 为非提示消息可能承担的三种角色分别命名：注入上下文、召回会话、steering。
+
+`TranscriptAdapter` 与历史折叠为每个 `ContextMessageNode` 附加一份 `provenance` 视图，由 `contextProvenance()` 仅依据持久来源计算得出。它返回 `role`（`inject`，跨会话快照则为 `recall`）与命名生产者的 `label`。`ContextInjectionRow` 以角色作为标题，并按 `ToolRow` 摘要的几何在标题旁展示该名称，因此折叠态就已经回答了「注入了什么、由谁注入」；141px 滚动视口与截断上限沿用[展开项决策](2026-07-30-web-context-injection-disclosure.md)，未作改动。视口里渲染什么，则由[上下文形态决策](2026-08-05-context-form-vocabulary.md)引入的、相互独立的形态轴决定。
+
+**名称从日志中读出，绝不来自客户端维护的生产者名称表。** `workspace-instructions` 以它对账过的去重指令文件路径命名，`session-reference` 以它读取的会话标题命名，插件来源以其记录的插件 id 命名，其余来源则以自身的 `kind` 命名——这正是可合并扩展联合类型有文档记载的默认分支。没有可读 kind 的来源降级为无名注入。于是新增或重命名的生产者无需客户端发版即可辨识，任何名称都不会相对代码变味，恢复、fork 或来自外部的日志与实时会话的投影结果完全一致。
+
+`recall` 覆盖 `session-reference`，因为它是当前唯一会把另一个会话的材料搬进本会话的已发布来源。今天没有任何 Web 叶子挂载 `dsh-session-reference`——它此前只有终端宿主——因此该分支的存在是为了日志可移植性，而不是为了某个已打包的生产方，其覆盖来自单元测试而非组装后的 Web 场景。
+
+`MessageItem` 为持久与待处理的 steering 气泡加上 `插话` 标注。runtime 会重放持久 `agent/inbox/spliced` 事件；如果一条用户来源的消息以相同身份从 `next-step` 被领取，后续 `user/message` 就投影为 `SteeringMessageNode`。从排队轮次领取的消息仍是 `UserMessageNode`，非用户来源的 next-step 消息仍是上下文。这推翻了[取消 steer 入口与插话装饰](../simplification/2026-07-31-web-ui-no-steer-entry-or-interjection-chrome.md)中的一条结论。当时移除徽章，是因为 composer 无法 steer，标签指向了用户做不到的动作。此后 composer 获得了 Steer 手势，却没有同步修订那份 note；本决策提供了它在「重新引入」条款中要求的产品决策，并订正了其中留下的过时事实。标注是这里唯一的 steering 装饰：composer 模式、Queue dock 的严格 steer 操作、待处理 steering 的生命周期仍归各自的所有者。
+
+## Alternatives considered
+
+**在客户端本地化生产者名称。** 以插件 id 为键的字典读起来确实比 `@deepseek-ai/dsh-system-prompt` 好，但它会在每次重命名时悄悄失准，每新增一个生产者都要改客户端，而且对来自外部的日志根本无法命名。日志已经承载的来源，比客户端自己编出来的措辞更有价值。
+
+**按来源 kind 注册呈现。** 展开项决策把键控的 context-view 槽位推迟到出现由来源自有的呈现需求为止。为一行命名并不构成独立呈现，而以「已挂载的生产者」为键的注册表恰恰会在最要紧的地方失效——生产者已不再挂载的恢复日志同样必须渲染出来。
+
+**在 host 侧计算角色与名称。** 那需要为每份事件副本附加一个视图，重复陈述持久来源已经说明的事实，并为每条上下文消息增加一个 wire 字段。改由投影为每个节点计算一次，与 transcript 其他派生事实同处一地。
+
+**给 steering 独立的行而非带标注的气泡。** steering 是一条在轮次中途抵达的用户消息；独立行形会打断右对齐的阅读节奏，并且要为零新增信息重复气泡上的复制与分支操作。
+
+**把同一套名称扩展到 trajectory 表格。** 不在本次范围内：该表格的上下文单元格有自己的文本推导，而 issue 要求的是对话面。
+
+## Testing
+
+- `packages/client/runtime` 单元覆盖钉住每个来源分支、名称字段缺失／为空／类型不符时的回退、来源没有可读 kind 时的无名降级，以及 reset 和实时 append 路径上的 steering 重建。
+- `packages/client/ui-conversation` 的 jsdom 覆盖钉住角色标题、标题旁的生产者名称、展开后该名称的留存、无名时的标题形态，以及持久与待处理气泡上的 steering 标注。
+- 无密钥的组装 Web 黄金基线携带带名称的标题栏与 steering 标注，因此证明这些标识的是组装后的 transcript，而不只是组件测试。
+
+## Consequences
+
+- 读者一眼即可归因 transcript 中每一条非提示消息；即便面对本客户端版本从未见过其生产者的日志，标题栏依然如实。
+- 只要来源仅携带插件 id，UI 中的生产者名称就呈现为包名形态（`dsh-tool-skill`、`@deepseek-ai/dsh-system-prompt`）。这是拒绝客户端名称表的代价；想要更好名称的生产者应当记录更好的来源。
+- `ContextMessageNode` 增加了一个必填字段，因此每一处构造该节点的代码——包括测试 fixture——都必须提供它。
+- 即使 agent loop 现在把已经接纳的 steering 记录为 `user/message`，`SteeringMessageNode` 仍是独立的呈现节点；它的身份来自持久 inbox 历史，而不是独立消息事件。
+- 在某个宿主挂载 `dsh-session-reference` 之前，`recall` 分支在已发布的 Web 叶子中没有生产者，只能通过别处写入的日志抵达。

+# Agent Note: Producer-declared context forms
+
+Status: implemented
+
+English | [中文](2026-08-05-context-form-vocabulary.zh.md)
+
+## Problem
+
+Every logged non-user `user/message` rendered through one body: the whole message serialized as inline JSON. A reader opening a row met `{ "content": [ { "type": "text", "text": "…\n\n…" } ], "source": { … } }`, where the escaping had collapsed the only thing worth reading — the model-facing prose — into a single line, and the provenance sat inside the same blob.
+
+Naming the producer in the header (the [source and steer marks decision](2026-08-04-web-context-source-and-steer-marks.md)) fixed *who added this*. It could not fix *what kind of thing was added*, because nothing in the log said so. Injected context is not one shape: a reconciled `AGENTS.md`, a catalog of available skills, a runtime policy snapshot, and a subagent's report are as different from each other as a terminal card is from a diff card, yet all four presented as the same wall of escaped JSON.
+
+The tool surface already solved this shape. `ToolCallView` has three cards, not one per tool, and a tool declares which card its call is. Context had no equivalent: no vocabulary of shapes, and no way for a producer to say which one it emits.
+
+## Decision
+
+`MessageSource` gains an optional producer-declared `form: ContextForm` — a small tagged vocabulary of information *shapes*, independent of `kind`:
+
+- `kind` answers **who produced this** and remains pure provenance.
+- `form` answers **what shape of information it is**. Several producers may share one form, and one producer may emit more than one over a session.
+
+The vocabulary is semantic, never visual. A value states that the content is a file's instructions or a catalog of available items; colors, icons, ordering, and collapse defaults are the consumer's business and must not enter the union. It grows one value at a time, as producers gain the structured fields their form needs. This release declares two:
+
+**`instructions`** — instructions read out of workspace files. `workspace-context` declares it on both the startup baseline and later deltas; its existing `changes[]` already carried the paths, actions, and digests the presentation needs, so no field was added. The body lists the reconciled files above the text, and keeps the `<system-reminder>` framing verbatim: the framing is part of what the model read, so hiding it would misreport the request.
+
+**`catalog`** — a catalog of items available this session, republished as it changes. `dsh-tool-skill` moves off the shared `plugin` kind to its own `skill-catalog` source carrying `entries` (the exact `name`/`description` pairs published) and `update` on a replacement, which the body renders as a replacement notice. The body lists those entries instead of re-parsing the `<available_skills>` block out of the prose.
+
+Entries record the published fact **unescaped**. The pseudo-XML escaping belongs to the `<available_skills>` frame, which exists for the model, so it is applied when rendering that frame and never stored; otherwise a consumer would have to know the frame's encoding to display a description containing `<`, and the same frame knowledge this decision removes would leak back in another shape. `escapeText` is deterministic and injective, so digesting the unescaped entries preserves republish semantics exactly, and the model-facing text stays byte-identical.
+
+That move also relocates catalog **identity**: the republish digest now covers the durable entries rather than the rendered text, so the model-facing framing can no longer decide whether a republish is needed, and the text-slicing that recovered entries from a logged message is gone. A resumed session whose newest catalog predates this change republishes once, which the pre-release stance permits. One case does not self-heal: if that old-format catalog is the only one and the current view has no skills, the plugin sees no published catalog and emits no tombstone, so the model keeps a stale catalog nothing replaces. The pre-release stance ("backends reject old on-disk formats") permits it; it is recorded here rather than left to the optimistic path.
+
+**`snapshot`** — current state that a later snapshot from the same producer supersedes. The runtime-context snapshot, `time-context`, and `tmux-context` declare it. `renderContextSections()` exposes the assembly's named contributions, which `renderContextSnapshot()` already joined for the model, so the body attributes each part to the subsystem that produced it without re-splitting joined prose. The two single-contribution producers record one section each. The cleared runtime-context marker has no contributions left and declares no form.
+
+**`notice`** — a one-off account of something that just happened. `tool-tasks`, `tool-goal` wrap-up, `plan-mode` switches, and `repeat-tool-guard` reminders declare it with a `summary`, which rides the **collapsed** row: a notice is meant to be read without expanding at all. The summary is bounded where its inputs are caller text (a task's label and status detail have no length of their own). Goal state changes remain domain-owned `goal/change` events rather than model context, so they declare no form.
+
+**`relay`** — a message another agent addressed to this one. Both subagent-addressed sources declare it; the sender is shown as the opaque session id the source already records, because this client cannot resolve it to a title.
+
+**`recall`** — material lifted out of another session's log. `session-reference` declares it and needed no new field: its references already record the label, retained and omitted counts, and truncation flag, which the body shows first, because recalled context is bounded on the way in and a card that hid the omitted count would overstate what the model received.
+
+Both readers are **all-or-nothing**: one unreadable entry disqualifies the record rather than being dropped, because a body that replaces the model-facing text must not present a confident but incomplete account of what the model read. The row's form marker reports what actually rendered, not what was declared.
+
+The producer side validates the same durable data with the same posture. `catalogHistory` reads `source.entries` out of `agent.session.events`, which on resume or fork is a JSONL/SQLite seed whose validation only guarantees a source object with a non-empty `kind` — no per-kind field is checked. An unreadable catalog is therefore skipped as "not this plugin's record", the posture the replaced content digest had; throwing there would fail every later step of that session at the latest, least diagnosable point.
+
+Everything else — including a form this UI version does not present, a form absent from the source, and a `catalog` whose entries are unusable — renders the **opaque** body: the model-facing text with its real line breaks, then the remaining provenance as fields. Opaque is the documented default, not a leftover bin. A resumed, forked, or foreign log must render whether or not its producer is mounted here, which is also why the classification lives in the durable source rather than in a client-side table keyed by producer.
+
+## Why not a presenter registry
+
+The tool seam pairs its vocabulary with `presentCall(args)`, a host-side pure function each tool implements. Context deliberately has no equivalent, because the input differs in ownership: a tool's `args` are generated by the **model** against a model-facing schema, so a translation step is unavoidable; a context `source` is constructed by the **producing plugin** itself, under no external constraint, and can simply record the facts a presentation needs. Adding a registry would have bought a translation nobody needs, at the cost of a host computation point, a wire field per context message, and a browser bundle for every producing package (the client purity gate forbids host packages from contributing components).
+
+## Alternatives considered
+
+**Map source kinds to renderers in the client.** Cheapest to write and requires no format change, but it puts producer knowledge back in the client: every new kind then needs a client release to render as anything but opaque, and a foreign log cannot be classified at all. It also reintroduces exactly the coupling the [source and steer marks decision](2026-08-04-web-context-source-and-steer-marks.md) removed for labels.
+
+**Reuse `kind` as the form.** One discriminant is simpler, and `workspace-instructions` is already 1:1 with its form. It breaks on the shared shapes: three producers emit runtime snapshots today, and folding them into one kind would erase their provenance. Two axes keep provenance exact while letting presentations be shared.
+
+**Let the client parse the model-facing prose.** The entries and file sections are visibly structured in the text. Parsing them couples the presentation to prompt wording, so every reword silently breaks a card — the same reason catalog identity moved off the text.
+
+**Render instructions as Markdown.** The body is a Markdown file and would read better rendered. The text also carries `<system-reminder>` framing, which the Markdown renderer drops as raw HTML, so a Markdown body would silently hide part of what the model read. Deferred until the producer records per-file content structurally.
+
+## Testing
+
+- `packages/client/runtime` pins the form projection, including the unknown, empty, wrongly-typed, and absent values that must degrade to opaque.
+- `packages/client/ui-conversation` pins each body: the opaque body's preserved line breaks and provenance fields, the instructions body's file list and verbatim framing, the catalog body's entry list, and a catalog with unusable entries falling back to opaque.
+- `packages/skill/tool-skill` pins the new source on first publication and replacement, republish behavior driven by the durable entries, and a malformed durable catalog leaving step observation intact.
+- The keyless assembled-Web seeded-history scenario expands a real `instructions` context in Chromium and asserts its file list, verbatim framing, and the unchanged disclosure geometry. `catalog` has no assembled coverage: the hermetic scaffold publishes no skills, so no catalog reaches a browser scenario.
+
+## Consequences
+
+- A reader can tell what was added without expanding, and reading it no longer means reading escaped JSON.
+- The durable `MessageSource` now carries a semantic classification beside provenance. The boundary is load-bearing: facts and shape only, never presentation. A producer that wants a better card records better facts.
+- Catalog identity no longer depends on the model-facing prose, deleting the text-slicing path that could mistake a reworded catalog for a changed one.
+- Every shipped producer except the two hook bridges now declares a form. The bridges stay opaque by design: their content is whatever an external program printed, so no shape can be promised for it. Unknown kinds and unreadable records land there too.
+- `ContextFormed` is discriminated by `form`, so a producer cannot declare a shape without the facts that shape is presented from — a `notice` without its summary, or a `snapshot` without its sections, fails to compile.

+# Agent Note：由生产方声明的上下文形态
+
+Status: implemented
+
+[English](2026-08-05-context-form-vocabulary.md) | 中文
+
+## Problem
+
+每一条已记录的非用户 `user/message` 都通过同一个内容区渲染：把整条消息序列化成内联 JSON。读者展开一行，看到的是 `{ "content": [ { "type": "text", "text": "…\n\n…" } ], "source": { … } }`——转义把唯一值得读的东西（面向模型的散文）压成了一行，而来源信息又和它挤在同一坨里。
+
+在标题栏写出生产者（[来源与 steer 标识决策](2026-08-04-web-context-source-and-steer-marks.md)）解决了「这是谁加的」。它解决不了「加进来的是什么东西」，因为日志里根本没有这句话。注入上下文不是一种形状：对账后的 `AGENTS.md`、可用 skill 的目录、运行时策略快照、子 agent 的汇报，彼此之间的差别不亚于终端卡片与 diff 卡片，然而这四者呈现出来是同一堵转义 JSON 的墙。
+
+工具面早就解决过同一个形状问题。`ToolCallView` 只有三种卡片，而不是每个工具一种，由工具自己声明本次调用属于哪一种。上下文没有对应物：既没有形状词汇表，生产方也无从声明自己发出的是哪一种。
+
+## Decision
+
+`MessageSource` 新增一个可选、由生产方声明的 `form: ContextForm`——一份关于信息**形状**的小型 tagged 词汇表，与 `kind` 相互独立：
+
+- `kind` 回答**由谁产生**，保持纯粹的溯源语义。
+- `form` 回答**这是何种形态的信息**。多个生产方可以共用一种形态，一个生产方在一次会话中也可以发出多种。
+
+该词汇表是语义的，绝不涉及视觉。取值只陈述「内容是某个文件的指令」或「是一份可用项目录」；颜色、图标、排序、默认折叠状态归消费方管，不得进入这个联合类型。它随生产方补齐各自形态所需的结构化字段而逐个增长。本次声明两个：
+
+**`instructions`**——从工作区文件中读出的指令。`workspace-context` 在启动基线与后续增量上都声明它；其既有的 `changes[]` 已经携带了呈现所需的路径、动作与 digest，因此没有新增字段。内容区在正文之上列出对账过的文件，并原样保留 `<system-reminder>` 包装：那层包装本就是模型读到的一部分，隐藏它会歪曲这次请求。
+
+**`catalog`**——本会话可用项的目录，随变化重新发布。`dsh-tool-skill` 从共享的 `plugin` kind 迁到自有的 `skill-catalog` 来源，携带 `entries`（本次发布的 `name`／`description` 对）与替换目录上的 `update`，后者由内容区渲染成替换提示。内容区直接列出这些条目，不再从散文里反解 `<available_skills>` 块。
+
+条目记录的是**未转义**的发布事实。伪 XML 转义属于 `<available_skills>` 这层为模型而设的框架，因此只在渲染该框架时施加、从不存储；否则消费方要正确展示含 `<` 的描述就得知道框架的编码方式，本决策刚移除的框架知识会换一种形式泄漏回来。`escapeText` 确定且单射，故对未转义条目取 digest 与此前完全等价，重新发布语义不变，面向模型的文本逐字节不变。
+
+这次迁移同时挪动了目录的**身份**：重新发布用的 digest 现在覆盖持久条目而非渲染文本，于是面向模型的包装再也无法左右是否需要重新发布，那段从已记录消息里切出条目的文本切分逻辑也随之删除。若恢复的会话中最新目录早于本次改动，会重新发布一次——发布前阶段的姿态允许这样做。有一种情形不会自愈：当那份旧格式目录是唯一的一份、且当前视图没有任何 skill 时，插件看不到已发布目录，也就不会发出 tombstone，模型手里会留着一份无人替换的过期目录。发布前阶段的姿态（「后端拒绝旧的磁盘格式」）允许这一点；此处如实记录，而不是只写乐观路径。
+
+**`snapshot`**——会被同一生产方后续快照取代的当前状态。运行时快照、`time-context`、`tmux-context` 声明它。`renderContextSections()` 暴露出装配时的具名贡献——`renderContextSnapshot()` 本来就是把它们拼给模型的——因此内容区能把每一段归属到产生它的子系统，而不必去切分已经拼好的散文。两个单贡献生产方各记录一段。运行时快照的「已清空」标记没有任何贡献可归属，因此不声明形态。
+
+**`notice`**——刚刚发生了什么的一次性说明。`tool-tasks`、`tool-goal` 收尾、`plan-mode` 切换与 `repeat-tool-guard` 提醒都带 `summary` 声明它，而该摘要出现在**折叠态**行上：notice 的全部意义就是不展开也能读完。摘要在其输入是调用方文本时自行封顶（任务的 label 与状态 detail 本身没有长度约束）。Goal 状态变更仍是由领域层持有的 `goal/change` 事件，而非模型上下文，因此不声明 form。
+
+**`relay`**——另一个 agent 发给本 agent 的消息。两个子 agent 定向来源都声明它；发送方以来源已记录的不透明会话 id 呈现，因为本客户端无法把它解析成标题。
+
+**`recall`**——从另一个会话日志搬来的材料。`session-reference` 声明它，且不需要新增字段：其 references 已经记录了标题、保留与省略条数、截断标记，内容区把这些放在最前面——召回上下文在进入时是有界的，隐藏省略条数的卡片会夸大模型实际收到的内容。
+
+两个读取器都是**全有或全无**：一条不可读的条目即判定整条记录不可用，而不是把它丢掉——会替换掉面向模型文本的内容区，不得给出自信但残缺的「模型读到了什么」。行上的形态标记报告的是实际渲染出的形态，而非声明的形态。
+
+生产方一侧对同一份持久数据采取同样的姿态。`catalogHistory` 从 `agent.session.events` 读 `source.entries`，而恢复或 fork 时它来自 JSONL／SQLite 种子，种子验证只保证来源是带非空 `kind` 的对象，不校验任何 kind 特有字段。因此不可读的目录被当作「不是本插件的记录」跳过——正是被替换掉的内容 digest 原有的姿态；在那里抛错会让该会话此后每一步都在最晚、最难定位的点失败。
+
+其余一切——包括本 UI 版本不呈现的形态、来源未声明形态、以及条目不可用的 `catalog`——一律渲染 **opaque** 内容区：按真实换行展示面向模型的文本，其后把剩余来源信息列成字段。opaque 是有文档的默认，不是兜底垃圾桶。恢复的、fork 的、外部写入的日志，无论其生产方是否挂载在此处都必须渲染得出来——这同样是分类信息必须落在持久来源里、而不是落在客户端以生产方为键的表里的原因。
+
+## 为什么不做 presenter 注册表
+
+工具接缝把它的词汇表与 `presentCall(args)` 配对，那是每个工具在 host 侧实现的纯函数。上下文刻意不设对应物，因为输入的归属不同：工具的 `args` 由**模型**按面向模型的 schema 生成，翻译步骤无法回避；而上下文的 `source` 由**生产方插件**自己构造，不受任何外部约束，完全可以直接记录呈现所需的事实。加一层注册表买到的是一次没人需要的翻译，代价却是一个 host 计算点、每条上下文消息一个 wire 字段、以及每个生产方包都要出浏览器 bundle（客户端纯度门禁禁止 host 包贡献组件）。
+
+## Alternatives considered
+
+**在客户端把来源 kind 映射到渲染器。** 写起来最省，也不用改格式，但它把生产方知识放回了客户端：此后每新增一个 kind 都要客户端发版才能渲染成 opaque 以外的东西，而外部日志根本无法分类。它还会重新引入[来源与 steer 标识决策](2026-08-04-web-context-source-and-steer-marks.md)刚为名称去掉的那种耦合。
+
+**复用 `kind` 充当形态。** 单一判别式更简单，`workspace-instructions` 本来也与它的形态一一对应。但它在共享形状上就崩了：今天有三个生产方发出运行时快照，把它们并成一个 kind 会抹掉各自的溯源。两根轴既保住溯源的精确，又让呈现可以共享。
+
+**让客户端解析面向模型的散文。** 条目与文件分节在文本里确实有可见结构。解析它们会把呈现耦合到 prompt 措辞上，于是每改一次文案就静默碎掉一张卡——这也正是目录身份从文本上迁走的原因。
+
+**把 instructions 渲染成 Markdown。** 正文本来就是 Markdown 文件，渲染出来更好读。但文本同时携带 `<system-reminder>` 包装，Markdown 渲染器会把它当原始 HTML 丢弃，于是 Markdown 内容区会悄悄隐藏模型读到的一部分。推迟到生产方按文件结构化记录内容之后再做。
+
+## Testing
+
+- `packages/client/runtime` 钉住形态投影，包括必须降级为 opaque 的未知值、空值、类型不符与缺失。
+- `packages/client/ui-conversation` 逐个钉住内容区：opaque 的换行留存与来源字段、instructions 的文件列表与原样包装、catalog 的条目列表，以及条目不可用的 catalog 回落到 opaque。
+- `packages/skill/tool-skill` 钉住首次发布与替换时的新来源、由持久条目驱动的重新发布行为，以及畸形持久目录不打断步骤观察。
+- 无密钥的组装 Web seeded-history 场景在 Chromium 中展开一条真实的 `instructions` 上下文，断言其文件列表、原样包装与未改动的展开项几何。`catalog` 没有组装态覆盖：隔离脚手架不发布任何 skill，因此没有目录能进入浏览器场景。
+
+## Consequences
+
+- 读者不展开就能知道加进来的是什么，展开之后读到的也不再是转义 JSON。
+- 持久 `MessageSource` 现在在溯源之外还承载一个语义分类。这条边界是承重的：只放事实与形状，绝不放呈现。想要更好卡片的生产方应当记录更好的事实。
+- 目录身份不再依赖面向模型的散文，删掉了那条可能把「改了措辞」误判为「改了内容」的文本切分路径。
+- 除两个 hook 桥接外，每个已发布的生产方现在都声明了形态。桥接按设计保持 opaque：其内容是外部程序打印出来的任意文本，无法承诺任何形状。未知 kind 与不可读记录同样落在这里。
+- `ContextFormed` 按 `form` 判别，因此生产方无法在缺少该形态所需事实的情况下声明它——没有 summary 的 `notice`、没有 sections 的 `snapshot`，都会编译失败。

+**Hide durable steer `user/message` content from the transcript.** Would lie on replay when an external client steers; rejected in favor of a plain bubble.
 
 **Keep the mode parameter but only ever pass `'queue'`.** Leaves dead API surface and tests that invent `'steer'` paths the composer cannot reach.
 
 ## Consequences
 
-- Web users cannot steer from the composer or `ctx.conversation.send`; stop/cancel and Queue remain the only mid-turn controls.
-- Host-wire and non-Web clients can still steer; the Web client shows those messages without labeling them as interjections.
+- **Superseded in part.** Decision bullets 1 and 3 through 5 no longer describe master: composer steering shipped later, and the [context-source and steer marks decision](../feature/2026-08-04-web-context-source-and-steer-marks.md) owns its caption. The current facts follow.
+- Host steering ownership is unchanged: agent-loop drain, session events, and the wire mode remain load-bearing for ACP, automation, and non-Web clients.
+- `ConversationService.send(text)` still takes no mode and always queues; the composer's Steer gesture uses `session.prompt(mode: 'steer')` instead.
+- Durable steer `user/message` content still folds into the transcript, so an externally submitted steer stays truthful on replay. It now carries the interjection caption instead of rendering as a bare bubble.
 - Non-user next-step items (`agent.inject` context: approval notices, task completion, attached snapshots) broadcast with the `context` placement and never render as pending steering bubbles; they stay invisible until claimed as durable `user/message` context cards.
-- Reintroducing a dedicated steer UI would need a new product decision; do not revive the mode union or badge without one.
 
 ## Testing
 
-- `packages/client/ui-conversation` unit/jsdom coverage: input machine enter/sink, ConversationService routing, MessageItem steering arm (no 「插话」), InputBar submit.

 ## Streaming
 
 Adapters emit a raw **chunk** protocol; the loop logs the chunks (replay fidelity) while feeding the same chunks through a `BlockAssembler` to rebuild blocks and messages. `StreamChunk` is a closed discriminated union over `type` — `block-start`, `text-delta`, `reasoning-delta`, `tool-call-delta`, `block-end`, `usage`, `finish`.

 适配器发出原始**分片**协议；循环记录分片（回放保真度），同时将同一批分片送入 `BlockAssembler` 以重建块和消息。`StreamChunk` 是基于 `type` 的封闭判别联合——`block-start`、`text-delta`、`reasoning-delta`、`tool-call-delta`、`block-end`、`usage`、`finish`。
