Subject: [PATCH 01/42] fix(ui): separate navigation pins from selection and
 show menu icons (#6883)

* fix(ui): separate navigation pins from selection and show menu icons

* fix(ui): simplify More menus and fold conversation views on resize

* test(ui): fix navigation CI regressions and refresh catalogs

* refactor(ui): render sidebar panel icons directly

* fix(ui): keep Chat visible and stop persisting navigation pins

* refactor(ui): drop unreachable pin validation from in-memory stores

 With Coding Tools off, the shell hides only Trajectory; other plugin-contributed Views remain available. The View tab bar is hidden when fewer than two Views are available.

-While the root-scoped `conversation.session.header.views.actions` list has registrations, a **More conversation views** button with a tooltip follows the View tabs in the tab row. It opens a menu whose rows are that list's registrations. Each receives `entries` (available Views in registration order with `id`, `label`, and `pinned`; Chat is never listed), `onOpen(id)`, which selects the View in this Session, `onPinnedChange(id, pinned)`, and `onDismiss()`, which closes the menu. The header keeps one root list of unpinned View ids in browser `localStorage` under `dsh.slot.manual-order.conversation.view.v1`, stored as `{ "unpinned": string[] }` and shared by every Session; the tab bar omits unpinned Views, and Chat always shows. The tab bar's visibility counts available Views, not pinned ones, so the bar and More stay while every other View is unpinned. Unpinning the active View leaves its content selected and keeps its tab, with `aria-selected`, until another View is selected. Ids of Views that are not registered stay stored; stored content other than a string array shows every tab.
+While the root-scoped `conversation.session.header.views.actions` list has registrations, a **More conversation views** button with a tooltip follows the View tabs in the tab row. It opens a menu whose rows are that list's registrations. Each receives `entries` (Views outside the header in registration order with `id`, `label`, `pinned`, and `active`; Chat is never listed), `onOpen(id)`, which selects the View in this Session, `onPinnedChange(id, pinned)`, and `onDismiss()`, which closes the menu. The header keeps an in-memory list of unpinned View ids shared by every Session; the tab bar omits unpinned Views and places registered Chat first so it always remains outside More. Plugin reload resets pin choices, and legacy localStorage values are ignored. The tab bar's visibility counts available Views, not pinned ones, so the bar and More stay while every other View is unpinned. Unpinning the active View hides its tab immediately without changing the selected content. More lists only Views outside the header and identifies the current View through `active`. The header reads its available row width, reserves 48px for More and padding, and estimates 120px per tab. Remaining Views keep registration order in More. A single ResizeObserver watches the tab row so window resizing and sidebar expansion update the split; active selection does not change the order. The observer disconnects when the row is removed. If ResizeObserver is unavailable, the initial width calculation still applies without subsequent observation. The More button highlights and names the active View in its tooltip when that View is folded. Individual tabs are not measured. At least one preferred tab remains outside, and long labels truncate with a full-name tooltip. Unregistered View ids remain in the in-memory pin list until plugin reload.
 
 The composer registers the File command action and owns its label, availability, and native file-dialog callback. Menu availability and invocation both consult the mounted composer's current attachment-intake policy. Unmounting or locking the composer disables that action; disposing the plugin removes its registration. The callback binding stays inside the input module.

+root 作用域的 `conversation.session.header.views.actions` list 有注册项时，标签行中的 View 标签之后显示带提示框的**更多会话视图**按钮。它打开的菜单以该 list 的注册项为菜单行。每个注册项接收 `entries`（按注册顺序的头部之外的 View，含 `id`、`label`、`pinned` 与 `active`；不含 Chat）、在本 Session 选择 View 的 `onOpen(id)`、`onPinnedChange(id, pinned)`，以及关闭菜单的 `onDismiss()`。头部在内存中保存所有 Session 共用的已收起 View id 列表；标签栏不显示已收起的 View，并将已注册的 Chat 放在首位，确保它始终留在更多菜单外。插件重新加载时 Pin 选择重置，不读取旧 localStorage 值。标签栏是否显示按可用 View 计算，不按已固定的 View 计算，因此其他 View 全部收起时，标签栏和“更多”仍然显示。收起当前激活的 View 会立即隐藏其标签，但不会切走其内容。更多菜单仅包含头部之外的 View，通过 `active` 标识当前 View。头部读取当前行可用宽度，为更多按钮与内边距预留 48px，每个标签估算 120px，其余 View 按注册顺序进入更多。单个 ResizeObserver 观察标签行，使窗口缩放和侧栏展开能够更新分组；当前选中项变化不改变顺序。标签行移除时断开观察。如果环境没有 ResizeObserver，仍按初始宽度计算，但不继续观察。当前 View 收起时，更多按钮高亮并在提示框中显示其名称。不逐项测量标签。至少保留一个优先展示的外部标签，长标题截断并通过提示框提供全名。未注册 View 的 id 保留在内存 Pin 列表中，直到插件重新加载。
 
 输入框注册「文件」命令动作，负责其标题、可用性和原生文件选择器回调。菜单可用性与实际调用都读取已挂载输入框当前的附件接收策略。输入框卸载或锁定后该动作不可用，插件 dispose（资源释放）时移除注册。回调绑定留在输入模块内部。

 The `@deepseek-ai/dsh-web-app` bundle loads this package by default; it needs no Plugins switch or profile selection. A region shows its More button only while its actions slot has a registration, so unloading this package removes all three buttons.
 
-Open **More** beneath the left navigation entries, **More conversation views** after the Conversation View tabs, or **More tools** after the right-sidebar guide cards. Each menu lists the region's customizable entries in registration order; Plugins, Chat, and Workspace files always show and are not listed. Selecting an entry's name closes the menu and opens the entry without changing its pin state. The separate pin button pins or unpins the region's launcher and keeps the menu open; a filled pin marks a pinned entry. Unpinned entries stay reachable through the menu, and pin choices persist across reloads. Long entry names wrap, except in the More tools menu, where they truncate to one line.
+Open **More** beneath the left navigation entries, **More conversation views** after the Conversation View tabs, or **More tools** after the right-sidebar guide cards. Left-sidebar and guide menus offer only **Browse other plugins** and **Create your plugin**. The Conversation menu also lists folded Views before those actions and marks the active View. None of these menus provide pin controls or sorting.
 
-**Browse other plugins** opens the Plugins main list without opening an installation dialog. **Create your plugin** opens a new or reusable blank Session with the Creator preset and adds a short localized request for a plugin in that region to its draft: an empty draft takes the request as its text, and an existing draft keeps its text, references, and attachments with the request appended as a new paragraph. It never sends a message. Review and send the draft yourself. Both actions remain available when a region has no customizable entries; an empty list adds no separator.

Browsing then calls `pluginNavigation.openList()`. Creation then calls `uiWorkspace.startSession(undefined, { agentPreset: 'cordis', prompt, whenDraftExists: 'append' })` with the region's localized prompt; it does not go through `ui-agent-preset`, so the preset chip plays no introduction.

 Each `guide` entry has an `id` unique within its provider. The guide renders `sidebar.right.tab.guide.entry` by the active definition id, forwarding the entry id, resolved title and optional description, plus the framework `useTabInfo` hook. A provider can register a custom card under its definition id; otherwise the standard icon/title button renders. The sidebar owns width and placement, while custom components own their markup and interaction. Guide cards use the shared R20 radius, including hover fills and provider-owned split buttons. Entry identity remains stable across sorting and unrelated registrations. Unboxed shortcut text aligns at the right. The terminal shell menu sits beside its entry title.
 
-While the root-scoped `sidebar.right.tab.guide.actions` list has registrations, a **More tools** card follows the guide cards. Its menu end-aligns to the card, is at least as wide as the card, and grows with its rows up to 480px or the viewport width minus 24px. The menu rows are that list's registrations. Each receives `entries` (cards in registry order with `id`, `label`, and `pinned`; kind `files` is never listed), `onOpen(id)`, which opens the card's tab type in the guide's place, `onPinnedChange(id, pinned)`, and `onDismiss()`, which closes the menu. The guide keeps one root list of unpinned card ids, each `kind:entry id`, in browser `localStorage` under `dsh.slot.manual-order.sidebar.right.tab.guide.list.v1`, stored as `{ "unpinned": string[] }`; the key reserves the name of a future guide list slot. The kind identifies a card instead of the provider id, so a pin choice survives an extension taking over that kind with the same entry id. Cards of kind `files` always show. Unpinning hides only the card; it closes no tab and changes neither tab-type registration nor the default page. Description density follows the visible card count. Ids of cards that are not registered stay stored; stored content other than a string array shows every card.

The guide keeps an in-memory list of unpinned card ids, each `kind:entry id`. Plugin reload resets pin choices; legacy localStorage values are ignored. The default More menu only offers plugin browsing and creation; pin callbacks remain available to other registrations.

Unpinning hides only the card; it closes no tab and changes neither tab-type registration nor the default page. Description density follows the visible card count. Unregistered card ids remain in memory until plugin reload.
 
 A tab type can declare `multiple: true` for independent instances such as terminals. Each open receives a distinct content address, so placement and docking preserve those instances; ordinary pages retain per-pane uniqueness.

 Plugins add an icon component to the root-scoped `sidebar.panellist` list with an `id`, optional `order`, and a string or locale-aware `label`. The same id addresses the component registered in the layout's root-scoped `main` keyed slot; selecting a missing main entry throws without changing the current selection. The label supplies plain visible text, the accessible name, and the collapsed tooltip. Expanded navigation rows have a 2px gap. Each row reads its own selected state through `usePanelInfo`; moving DOM focus to search or a directory picker does not change the displayed panel or its selected row. With no panel registrations, neither the list nor spacing for it is rendered. The shipped composition registers no example panel.
 
-While the root-scoped `sidebar.panellist.actions` list has registrations, a **More** button styled as a panel row follows the rows inside the navigation landmark; the collapsed rail shows its label as a tooltip. It opens a menu whose rows are that list's registrations. Each receives `entries` (customizable panels in registration order with `id`, `label`, and `pinned`; Plugins is never listed), `onOpen(id)`, which selects the panel, `onPinnedChange(id, pinned)`, and `onDismiss()`, which closes the menu. The sidebar keeps one root list of unpinned panel ids in browser `localStorage` under `dsh.slot.manual-order.sidebar.panellist.v1`, stored as `{ "unpinned": string[] }` and shared by every Session; the rows omit unpinned panels except the selected one, which keeps its row and `aria-current` until another panel is selected, and Plugins always shows. Unpinning hides only the row; the main panel, its registration, and the current selection stay unchanged. Ids of panels that are not registered stay stored, so a panel that registers again stays unpinned; stored content other than a string array shows every row.

The sidebar keeps one in-memory list of unpinned panel ids shared by every Session; Plugins always shows.

-The shell is pure composition: `SidebarRootComponentProps` composes the layout owner share, the global `useSessions` and `useWorkspaces` hooks, the declared brand, the `sidebar.workspaces` and `sidebar.settings` child slots, and injected navigation callbacks. Panel entries and their optional titles use the same composition path. Panel metadata is derived from list registrations and locale changes; selection belongs to the layout store. The injected `trackEntryClick(attributes)` forwards to `ctx.get('productAnalytics')?.track('sidebar_menu_click', attributes)`, and `selectPanel` only selects, so each control supplies its own entry and position.

Subject: [PATCH 02/42] feat(llm): follow the official /models listing on the
 DeepSeek API-key route (#6944)

* refactor(llm-deepseek): share the /models listing machinery

Move the account route's `/models` request and decoding, its
credential-scoped listing cache, and listed-catalog resolution with the
version gate into the shared DeepSeek Messages library, so a second
route can follow the same listing. Names drop the account prefix, the
cache takes each access's endpoint settings with the call, and it gains
`invalidate()` for a forced reload. `isBuiltInCatalog()` recognizes the
catalog an uncustomized `models` setting resolves to.

The account route keeps its behavior; only its imports and the
override diagnostic wording ("model listing") change.

* feat(llm-deepseek-api-key): follow the official /models listing

While `models` equals the built-in catalog and the Messages origin is
https://api.deepseek.com, `deepseek-official` serves the official
`GET /models` listing, authenticated with the API key in `x-api-key`.
Loading, refresh, fallback, merging, and the client-version gate match
the account route: the first access waits up to `modelsTimeoutMs`, a
listing older than `modelsMaxAgeMs` refreshes in the background on the
next access, a failure keeps the last good listing or the built-in
catalog, and listed models this build cannot serve are refused before
network I/O.

A customized `models` list replaces the catalog and requests nothing.
Switching between a customized catalog and the listing discards the
cached listing, so Restore defaults reloads it on the next access.

Suites that boot the route on the official endpoint now answer the
listing themselves instead of reaching the network.

* docs: describe the official route model listing

Document when `deepseek-official` follows the official `/models`
listing, its timing fields, customization precedence, and the forced
reload after Restore defaults in the API-key README, the shared
transport README, and the provider guide. Record the decision in a new
Agent Note, keep the account note's statement of where the shared
listing code lives current, and regenerate the configuration catalog.

* test(llm-deepseek-api-key): pin the once-per-listing hidden-entry diagnostic

* docs: regenerate module and event graphs for the shared listing

* fix(llm-deepseek-api-key): report credential failures on the model request

On the official endpoint, `connect` waited for the listing view, whose
credential lookup rethrew a malformed key or a credential-store failure
before the agent loop recorded the prompt. A failed lookup now resolves
the connection from the current listing view, so `resolveAuth` reports
the failure on the model request and the turn keeps the prompt and the
failed attempt. A caller abort still rejects.

* docs(llm-deepseek-api-key): name which hidden listing entries are logged

* test: keep unit suites off the official model listing

Suites that boot the DeepSeek routes with a dummy or inherited key now
request `GET https://api.deepseek.com/models` on the official endpoint.
A unit-lane setup file rejects that request at once, so such a suite
serves the built-in catalog instead of reaching production or waiting
out the listing deadline on a network that never answers; suites that
exercise the listing answer `fetch` themselves. Other requests pass
through unchanged.

* feat(llm-deepseek): read tool_update from the model listing

Both DeepSeek routes now take a listed model's Messages tool update mode
from `api_capabilities.anthropic_messages.tool_update`, alongside the
system prompt mode. `in-history` and `addition-only` replace the
bundled mode; any other value reads as `leading-only` and removes it.
An absent or `null` mode keeps the bundled one, so a listing that does
not declare the field leaves `deepseek-flash` on `addition-only`.

`system_prompt_update: null` likewise keeps the bundled mode now; it
previously read as `leading-only`, which a serializer writing empty
values as null would have turned into a cache-unfriendly downgrade.

* fix(llm-deepseek): sync the built-in context window with the official listing

The official `/models` listing declares a 1,048,576-token context window
for `deepseek-flash` and `deepseek-v4-pro`; the built-in catalog said
1,000,000, a decimal-versus-binary mismatch. Both built-in entries now
carry the listed value, so offline starts and listing failures size the
context the same way the listing does. The Models page shows the exact
count for these rows, since 1,048,576 has no decimal K/M spelling.

`defaultContextWindow`, the fallback for model ids the catalog does not
describe, stays 1,000,000.

* test(llm-deepseek-api-key): reject the stubbed listing request with an Error

* test(cli): keep the built SDK smoke off the official model listing

The SDK profile's initialize now resolves the deepseek-official catalog,
which requests GET https://api.deepseek.com/models on the official
endpoint. With the smoke's fixture key that request answers 401 and the
route warns on stderr, so the test's empty-stderr assertion failed in the
e2e and snapshots lanes. Point the run at a loopback mock and assert it
received no model call.

* test(llm-deepseek): compose the malformed-key turn without the native executor

release/dsh-0.2.1 predates @deepseek-ai/dsh-tool-executor-native; its tool
runtime executes tools itself. Compose the official-route turn the way
account-routing.spec.ts does on this branch.

* fix(llm-deepseek-api-key): gate nothing when the credential lookup fails

The listing cache switches scope only after it reads a credential, so a
failed lookup left `connect` serving the previous credential's listing.
After a key whose listing refuses a model was replaced by a malformed one,
`admit` refused that model with CLIENT_UPGRADE_REQUIRED before the turn
recorded the prompt, instead of `resolveAuth` reporting the credential
error on the request. Serve the built-in catalog without listing gates
when the lookup fails.

* test(llm-deepseek-api-key): pin the once-per-listing diagnostic across request preparation

The hidden-entry diagnostic test repeated the same discovery assertion to
prove a second pass reports nothing new, which read as a duplicate. Assert
the single warning after the request preparations instead; they resolve
the same listing, so dropping the per-listing deduplication still fails
the test.

* docs(llm-deepseek-api-key): note that a list matching an earlier built-in catalog counts as customized

Customization is judged against the running version's built-in catalog,
so a saved `models` list equal to an earlier version's catalog stops
following the listing once the built-in catalog changes, until Restore
defaults. Record the consequence in the Agent Note and the README's known
limitations.

+## Problem
+
+The `deepseek-official` route offered whatever its `models` setting held, and that setting defaults to the catalog bundled with each build. A model the DeepSeek API added reached API-key users only through a release, while the account route already followed the service's `GET /models` listing at the same origin. Unlike the account route's catalog, the official route's catalog is user-editable: the Models page stores an edited catalog in `models`, and a gateway behind `baseURL` declares its models there.

+- [`llm-deepseek-api-key`](../../../../packages/llm/llm-deepseek-api-key/README.md) follows `GET https://api.deepseek.com/models`, authenticated with the API key in `x-api-key`, only while the Messages origin is `https://api.deepseek.com` and `models` equals the built-in catalog. Any other endpoint or catalog sends no listing request.
+- Loading, refresh, fallback, merging, and the client-version gate are the [account route's](2026-09-24-deepseek-account-remote-model-catalog.md): a first access waits up to `modelsTimeoutMs`, a listing older than `modelsMaxAgeMs` refreshes in the background on the next access, a failure keeps the last good listing or the built-in catalog, and the cache lives in memory, keyed by endpoint and key fingerprint.
+- A customized `models` list wins whole: it replaces the catalog and stops listing requests. A list is customized when it resolves differently from the built-in catalog, because the schema default materializes an absent `models` as the built-in list and the Models page shows that default as its inherited rows.
+- Switching between a customized catalog and the listing invalidates the cache from a `loader/volatile-update` listener, so Restore defaults reloads the listing on the next access even when the cached listing is fresh.
+- The listing request, its cache, catalog resolution, and the gate live in the shared [Messages transport](../../../../packages/llm/llm-deepseek/README.md) because two routes consume them; the transport's provider hooks remain `connect` and `admit`.
+
+## Alternatives considered
+
+**Follow the listing on every endpoint.** A gateway that publishes an OpenAI-style `/models` returns entries without `api_capabilities.anthropic_messages`, which the decoder hides, so the route would offer no models. Every such gateway would also receive an extra request carrying the key.
+
+**Merge the customized catalog with the listing by model id.** Customized users would keep receiving new listed models, but a model the user deleted would return, and the Models page cannot hide one listed model.
+
+**Mark an unset `models` by removing its schema default.** An absent value would select the listing without comparing catalogs, but the Models page would lose the inherited rows it shows and copies, with their hidden `systemPromptUpdate` and `toolUpdate` fields, into a customized catalog. Rows copied from the generic model-discovery API would drop those fields.
+
+**Fetch once per process, or refresh on a timer.** A single fetch leaves a long-running Web or desktop host on its startup catalog, and one transient failure pins it to the built-in catalog. A timer sends requests while the route is idle. Access-triggered background refresh matches the account route.
+
+**Reuse the cached listing after Restore defaults.** The cache could serve a listing loaded before the customization for up to `modelsMaxAgeMs`; the request is cheap, so restoring always reloads it. The reload starts on the next access rather than inside the listener, which keeps credential lookup and its failures on the request path; the Web page's settings refresh makes that access right after the save.
+
+## Consequences
+
+- API-key users on the official endpoint receive listed models without a release, and an older build hides or refuses a model that needs a newer client, as account users' builds do.
+- A customized catalog receives no later listed models until Restore defaults, and a `models` list identical to the built-in catalog counts as uncustomized. The comparison uses the running version's built-in catalog, so a saved list equal to an earlier version's built-in catalog counts as customized once the built-in catalog changes.
+- The Models page shows the built-in rows while the listing is followed, so a model only the listing offers appears only in model selectors, and editing the page's catalog drops it.
+- The first catalog access on the official endpoint can wait up to `modelsTimeoutMs`, and a suite that boots the route there must answer the listing itself to stay off the network.

+# Agent Note: DeepSeek 官方路由在目录未自定义时跟随官方模型列表
+
+Status: implemented
+
+[English](2026-10-22-deepseek-official-model-listing.md) | 中文
+
+## 问题
+
+`deepseek-official` 路由提供的是 `models` 设置里的内容，而这个设置默认是每个构建自带的目录。DeepSeek API 新增的模型只能随发版到达 API key 用户，而账号路由已经在同一个 origin 上跟随服务端的 `GET /models` 列表。与账号路由不同，官方路由的目录可以由用户编辑：模型页把编辑后的目录存进 `models`，`baseURL` 后面的网关也在这里声明自己的模型。
+
+## 决策
+
+- [`llm-deepseek-api-key`](../../../../packages/llm/llm-deepseek-api-key/README.zh.md) 只在 Messages 的 origin 是 `https://api.deepseek.com`、且 `models` 等于内置目录时，跟随 `GET https://api.deepseek.com/models`，并用 `x-api-key` 携带 API key 鉴权。其他端点或目录不发列表请求。
+- 加载、刷新、兜底、合并与客户端版本门控沿用[账号路由](2026-09-24-deepseek-account-remote-model-catalog.zh.md)的规则：首次访问最多等待 `modelsTimeoutMs`，列表超过 `modelsMaxAgeMs` 后在下一次访问时后台刷新，失败时保留上一份成功的列表或使用内置目录，缓存只在内存中，以端点和 key 指纹为键。
+- 自定义的 `models` 列表整份优先：它替换目录，并停止列表请求。解析结果与内置目录不同的列表才算自定义，因为 schema 默认值会把缺省的 `models` 物化为内置列表，模型页也把这个默认值显示为继承的行。
+- 在自定义目录与列表之间切换时，一个 `loader/volatile-update` 监听器会让缓存失效，因此点恢复默认后，即使缓存的列表尚未过期，下一次访问也会重新加载。
+- 列表请求、缓存、目录解析和门控放在共享的 [Messages 传输包](../../../../packages/llm/llm-deepseek/README.zh.md)中，因为现在有两条路由使用它们；传输层的提供方钩子仍然只有 `connect` 和 `admit`。
+
+## 考虑过的替代方案
+
+**在所有端点上跟随列表。** 发布 OpenAI 风格 `/models` 的网关返回的条目没有 `api_capabilities.anthropic_messages`，解码器会隐藏它们，路由就不提供任何模型。每个这样的网关还会多收到一个携带 key 的请求。
+
+**按模型 id 合并自定义目录与列表。** 自定义用户会继续收到新列出的模型，但用户删掉的模型会重新出现，而模型页无法隐藏某一个列出的模型。
+
+**去掉 `models` 的 schema 默认值来标记未设置。** 缺省值不用比较目录就能选中列表，但模型页会失去它显示的继承行；这些行连同隐藏的 `systemPromptUpdate`、`toolUpdate` 字段会被复制进自定义目录。从通用模型发现 API 复制的行会丢掉这些字段。
+
+**每个进程只获取一次，或按定时器刷新。** 只获取一次会让常驻的 Web 或桌面宿主停留在启动时的目录，一次偶发失败就会让它固定在内置目录。定时器会在路由空闲时发请求。由访问触发的后台刷新与账号路由一致。
+
+**恢复默认后沿用缓存的列表。** 缓存可能在 `modelsMaxAgeMs` 内一直提供自定义之前加载的列表；列表请求代价很小，所以恢复默认总是重新加载。重新加载从下一次访问开始，而不是在监听器里进行，这样凭据查询及其失败都留在请求路径上；Web 页面保存后的设置刷新会立即发起这次访问。
+
+## 影响
+
+- 使用官方端点的 API key 用户无需发版就能看到列出的模型，旧构建会像账号用户的构建一样隐藏或拒绝需要新版客户端的模型。
+- 自定义目录在恢复默认之前收不到之后列出的模型；与内置目录完全相同的 `models` 列表视为未自定义。比较的是当前版本的内置目录，所以保存的列表若等于旧版本的内置目录，内置目录变化后就算作自定义。
+- 跟随列表期间，模型页仍显示内置的行，因此只有列表提供的模型只出现在模型选择器里，在模型页编辑目录会丢掉它。
+- 官方端点上的第一次目录访问可能等待最多 `modelsTimeoutMs`，在该端点上启动路由的测试套件必须自己应答列表请求，才能不访问网络。

 Keys are write-only. The page receives a redacted descriptor after saving, never the literal secret. The key is stored in `$DSH_HOME/.credentials.yaml`, while settings retain only its credential reference.
 
+With a key saved and the default endpoint, DeepSeek's models follow the list the DeepSeek API publishes. The list loads when the models are first needed, refreshes in the background about every ten minutes while they are in use, and falls back to the built-in models when it cannot load. Editing **Models** under **Customized settings** keeps your own list instead and stops following the published one; **Restore defaults** follows it again and reloads it. While the published list is in use, the card shows the built-in models, so a newly published model appears only in the model picker. The [API-key provider reference](../../../packages/llm/llm-deepseek-api-key/README.md) owns the listing, fallback, and gating rules.

 ## Add a third-party provider
 
 Choose **Add model provider**. The card opens on **Third-party model provider**: pick a provider dsh ships with — the list shows provider ids such as `anthropic`, `openai`, `moonshotai` for Kimi, or `zai` for GLM — enter its API key, and save. The installed catalog supplies the endpoint, protocol, and model list.

 A listed model is offered only when the current DeepSeek Harness version can serve it. A model that declares `client_requirements["deepseek-harness"].min_version` is offered when the current version is at least that version in semantic-version order, including prerelease tags such as `0.2.0-alpha.1` and `0.2.0-rc.1`. A prerelease orders below its release: `min_version: 0.2.1` refuses `0.2.1-alpha.2`, so a listing that admits prereleases declares the earliest one it admits, such as `0.2.1-alpha.0`. A model without that declaration is offered only when the built-in catalog knows its id; other listed models stay hidden. A request for a listed model the current version cannot serve fails before network I/O with `CLIENT_UPGRADE_REQUIRED`, which names the required and current versions, or with `MODEL_UNSUPPORTED`. Model ids the listing does not name pass through unchanged.
 
-Offered models take the listing's name, `context_window`, input modalities, and Messages system prompt mode over the bundled entry for the same id, which keeps its tool-update mode, image budgets, and description. `max_output_tokens` bounds the request default: a request that names no cap sends the smaller of `maxTokens` and that capability. The listing's effort levels are not read; every model offers `off`, `low`, `high`, and `max`.
+Offered models take the listing's name, `context_window`, input modalities, and Messages system prompt and tool update modes (`api_capabilities.anthropic_messages.system_prompt_update` and `tool_update`) over the bundled entry for the same id, which keeps its image budgets and description. A mode the listing omits or sets to `null` keeps the bundled one; any value other than the modes this build reads (`in-history` for system prompts; `in-history` or `addition-only` for tools) reads as `leading-only`, which removes the bundled mode. `max_output_tokens` bounds the request default: a request that names no cap sends the smaller of `maxTokens` and that capability. The listing's effort levels are not read; every model offers `off`, `low`, `high`, and `max`.
 
 `modelOverrides` adjusts single models without replacing the catalog. Keys are model ids; values take the fields of a [Messages `models` entry](../llm-deepseek/README.md#minimal-configuration), and unset fields inherit. Overrides apply over the listing and the bundled catalog; they cannot add models or make a refused model available. Listed capabilities do not bound an override: an override `maxTokens` above the listed `max_output_tokens` is sent as written, and the service rejects requests beyond its limits. An override that names a model neither the listing nor the built-in catalog describes, or that the listed model rejects, becomes the provider diagnostic on the Models page, which has no editor for this route. An override for a refused model that the built-in catalog does not describe is checked only once the current version can serve that model. The route has no `models` field; a configuration that still sets it fails at load and names `modelOverrides`. Edit `$DSH_HOME/profiles/<profile>/cordis.patch.yml`; the next request uses the change.

-`models` is an independently configurable catalog for this provider; defaults and protocol capabilities come from the shared transport. Discovery does not probe inference endpoints.

+`models` is an independently configurable catalog for this provider; defaults and protocol capabilities come from the shared transport. While `models` equals the built-in catalog and the Messages origin is the official API, `https://api.deepseek.com`, the route serves the official `GET https://api.deepseek.com/models` listing instead. Listing requests carry the API key in `x-api-key` and the harness `User-Agent`, and reject redirects; without an API key the route requests nothing. Any other endpoint, including one named by `baseURL` or `$DEEPSEEK_BASE_URL`, serves `models` and requests no listing. Discovery does not probe inference endpoints.
+
+The first access waits for the listing up to `modelsTimeoutMs`. Later accesses use the loaded listing and refresh it in the background once it is older than `modelsMaxAgeMs`; an idle route sends no requests. A failed or empty listing keeps the previous one; before any listing loads, the route serves the built-in catalog of the current version (`deepseek-flash` and `deepseek-v4-pro`). A listing HTTP 401 fails only that load. Each loaded listing, the first failure of a failing streak with the catalog it falls back to, and each listing entry hidden because its declarations are unreadable or unusable are written to stderr with the `[llm-deepseek-api-key]` tag; stdout remains available for protocol messages, and secrets are never logged.
+
+Listed models are offered, merged with this build's entries, and refused before network I/O with `CLIENT_UPGRADE_REQUIRED` or `MODEL_UNSUPPORTED` by the [account route's rules](../llm-deepseek-account/README.md#use-this-package); model ids the listing does not name pass through unchanged.
+
+A `models` list that differs from the built-in catalog replaces the catalog and stops listing requests; the Models page stores an edited catalog there. Removing that list, as **Restore defaults** on the Models page does, returns the route to the listing, and the next access loads the listing again even when the cached one is still fresh. A list identical to the built-in catalog counts as uncustomized.
+
+| Field | Default | Meaning |
+|---|---|---|
+| `modelsTimeoutMs` | `5,000` | Deadline of one listing request and of a first-access wait |
+| `modelsMaxAgeMs` | `600,000` | Listing age after which the next access refreshes it; a failed load retries after the same age |
+
+The settings namespace is the Cordis entry id, or the plugin name without an entry. Product profiles retain the official entry id `llm-deepseek` and use `llm-deepseek-account` for the account route.

+Registrations and listeners dispose with the plugin, and disposal aborts an in-flight listing request. Shared Host wiring supplies attachments, request extensions, anonymous identity, and atomic retry-policy updates; this plugin registers only its own route and uses the transport's `connect` and `admit` hooks for the listed catalog and the gate. The listing request, its cache, and catalog resolution come from the shared transport; the cache lives in memory and is keyed by endpoint and a SHA-256 of the key, so another key loads its own listing. A `loader/volatile-update` listener discards the cached listing whenever the route starts or stops following it.

-- The catalog is configuration metadata, not remote validation that a model is accepted; actual calls can still fail.
+- A configured catalog is configuration metadata, not remote validation that a model is accepted; actual calls can still fail.
+- The Models page shows the built-in catalog while the route follows the listing, so a model only the listing offers appears only in model selectors. Editing that catalog on the page stores the rows the page shows, which drops such a model until **Restore defaults**.
+- A customized catalog does not receive models the listing adds later.
+- Customization is judged against the running version's built-in catalog, so a saved `models` list equal to an earlier version's built-in catalog counts as customized once the built-in catalog changes and stops following the listing until **Restore defaults**.
+- The listing cache lives in memory; a start without network serves the built-in catalog until a listing loads.
+- A listing change during a running process reaches the Web model picker at its next catalog refresh; the plugin does not announce it.
+- When the current version can serve no listed model, the route offers no models.

 ```
 
-A request selects the route with `provider: deepseek-official`; the model id passes through to the wire, so new DeepSeek models need no re-registration. Omitted `models` advertises the text- and image-capable `deepseek-flash` alongside the text-only `deepseek-v4-pro`, each with a 1,000,000-token context window. An explicit list replaces those defaults, and core calls still pass unlisted model ids through as text-only routes. GUI selection requires a catalog entry; a saved selection can still submit requests after its catalog entry disappears. Clients, including model discovery tools, can read the advisory entries through `ctx.llm.listModels('deepseek-official')`. Image-capable entries may set `imagePixelBudget` to a positive integer or `low`, and may set `imageMaxBytes`. An entry may declare `systemPromptUpdate: in-history` when its endpoint reads the latest `system` message at any position of `messages` as the complete effective system prompt; the adapter reports the mode on the resolved model and the prepared call, and the agent loop then appends a changed prompt after the cached history instead of rewriting the leading system message ([decision rule](../../core/agent-loop/README.md#understand-the-implementation)). The default `deepseek-flash` entry declares this mode; other models require an explicit `models` declaration, and any value other than `in-history` fails at load with `llm-deepseek: catalog model "<id>" systemPromptUpdate must be "in-history" when present`.
+A request selects the route with `provider: deepseek-official`; the model id passes through to the wire, so new DeepSeek models need no re-registration. Omitted `models` advertises the text- and image-capable `deepseek-flash` alongside the text-only `deepseek-v4-pro`, each with the 1,048,576-token context window the official model listing declares. An explicit list replaces those defaults, and core calls still pass unlisted model ids through as text-only routes. On the official endpoint the API-key route follows the service's model listing while `models` holds those defaults ([listing rules](../llm-deepseek-api-key/README.md#use-this-package)). GUI selection requires a catalog entry; a saved selection can still submit requests after its catalog entry disappears. Clients, including model discovery tools, can read the advisory entries through `ctx.llm.listModels('deepseek-official')`. Image-capable entries may set `imagePixelBudget` to a positive integer or `low`, and may set `imageMaxBytes`. An entry may declare `systemPromptUpdate: in-history` when its endpoint reads the latest `system` message at any position of `messages` as the complete effective system prompt; the adapter reports the mode on the resolved model and the prepared call, and the agent loop then appends a changed prompt after the cached history instead of rewriting the leading system message ([decision rule](../../core/agent-loop/README.md#understand-the-implementation)).

 Non-2xx responses fail with stable codes: `AUTH` (401/403), `QUOTA`, `RATE_LIMIT`, `CONTEXT_WINDOW_EXCEEDED`, `INVALID_REQUEST`, `SERVER`, and `HTTP_<status>` otherwise; pre-response transport failures throw `TRANSPORT`, caller aborts throw `ABORTED`, and stream-idle expiry throws `TIMEOUT`. A request-extension field collision, or a rejected preparation from a directly supplied `prepareExtensions`, fails with `REQUEST_EXTENSION` and appends the cause chain to the message; a post-2xx acceptance failure is logged and the response still streams. A normalized-image rejection names every plausible attachment and its durable position when the provider does not identify a file id. Stale-file rejection removes every named mapping (or every mapping used by the attempt) in one upload-index update and permits one replacement model request. Protocol violations throw `STREAM_CLOSED` or `MALFORMED_RESPONSE`, and a terminal `stop` with no content blocks becomes `EMPTY_RESPONSE`, which the default retry policy retries. A request on the official route without an API key fails with `MISSING_CREDENTIAL`, and a malformed credential fails with `INVALID_CREDENTIAL` naming the reference to fix — never any part of the key.
 
-Provider plugins own catalog availability: the API-key route serves its configured `models` while its API key resolves, and the account route serves its account listing while signed in (see the [account provider](../llm-deepseek-account/README.md)). The transport supplies the bundled catalog, the catalog-entry field schemas, and capability resolution. A provider may also supply `connect(signal)`, which resolves the connection for exact-model lookups and prepared calls after provider-owned work such as a catalog load, and `admit(connection, model)`, which refuses a model before network I/O.
+Provider plugins own catalog availability.

The transport supplies the bundled catalog, the catalog-entry field schemas, and capability resolution, plus the listing machinery both routes share: `requestModelListing`, the credential-scoped `ModelListingCache`, and `resolveListedCatalog` with its client-version gate and `refuseListedModel`.

Subject: [PATCH 03/42] feat(client): publish the branch, slot, and access
 seams a served page reads

The Workspace tree gains the Host-published branch projection plus the
access-snapshot reads its rows, menu entries, and shortcuts consult; the
Conversation package moves branch handling into its own module and exposes the
input and slot declarations a page-local plugin composes. Chat, sidebar,
deliverables, and open-in-app publish the slot surfaces those readers fill, and
the document-relative route and HMR endpoint seams keep the served page's own
base.

 Native message images use separate user and output positions.

Both receive image sources, the authorized `loadImage`, and layout options through explicit props. Their official `MessageImages` entries call the shared root-scoped `conversation.images.content` Factory. Each position can be replaced independently without duplicating the gallery implementation.

 `UserStyleBubble` and the [source-specific wrappers](<src/client/chat/MessageItem.tsx#L157-L309>) retain the user row, keys, pending/echo markers, timestamps, copy controls, and other message actions. The content Factory reads neither source-specific models nor private Context, and is not a global user-content override entry point.
 
 Standalone Markdown images show contained previews and open the shared image lightbox; local paths resolve against the viewed workspace after settlement. Image file links keep their sidebar activation and show a thumbnail after hover dwell or keyboard focus. Escape dismisses the thumbnail.

+The Turn Tail branch action reads the Session-scope `useAccess('session/fork')` Hook and disappears while the calling Peer's access snapshot excludes that endpoint; the view always receives the `forkAt` handler. A branch names its child only while the snapshot includes `session/rename` for the source Session; otherwise the child keeps the Host's title and opens once the Session list carries it. A branch the Host refuses states why, on the Session it was asked of, through the composer's notice channel, as the Host's own message with the stable code beside it. The Session tree's branch verb shares the refusal notice and the rule for naming and opening a branch. These answers never replace Host authorization.

 The composer registers the File command action and owns its label, availability, and native file-dialog callback. Menu availability and invocation both consult the mounted composer's current attachment-intake policy. Unmounting or locking the composer disables that action; disposing the plugin removes its registration. The callback binding stays inside the input module.
 
+The composer reads its Session's access answers through the Session-scope `useAccess` Hook: Send disappears while the access snapshot excludes `session/prompt`, Stop while it excludes `session/cancel`, and file intake follows `fileUploads/upload`. A composer without a Session has no answer and keeps its ordinary controls. Stop and file intake recheck the live answer when invoked. These UI answers never replace Host authorization.
+
 `SessionInputShell` owns one Lexical editor per Session through its private [DraftEditorRuntime](src/client/input/editor/runtime.ts), while retaining submission, attachment selection, and recovery decisions. [DraftEditor](src/client/input/editor/DraftEditor.tsx) renders the borrowed editor; InputBar retains its Hooks and refs and installs DOM behavior through [view-binding](src/client/input/editor/view-binding.ts). Editor-facing types live in [draft-editor.ts](src/client/contract/draft-editor.ts), with shared input and submission types in [input.ts](src/client/contract/input.ts). Background editor updates retain the draft selection without changing the document selection or reclaiming focus from another control; explicit Composer focus restores its selection. This separation does not support simultaneous editable roots for one Session; [the two-stage isolation proposal](../../../.agents/notes/proposed/architecture/2026-09-14-composer-model-and-draft-editor.md) defines the remaining work.
 
 Drafts retain plain text and file, folder, and Session reference chips across Session switching and reload. Public input methods accept text; internal restoration and Workspace transfer preserve structured references. The input model imports saved content before its first published read; React only mounts that editor and binds the existing Conversation store writer. The original storage key accepts legacy strings and writes semantic snapshots without runtime node IDs. A pending skill catalog does not block editing: slash names remain ordinary text until a matching catalog entry arrives. Arrival rematches the current text without changing chips, selection, or Undo history. Browser-owned attachment File objects are not persisted by this mechanism. The [draft initialization decision](../../../.agents/notes/implemented/architecture/2026-09-30-structured-draft-initialization.md) defines ownership and restoration.

 输入框注册「文件」命令动作，负责其标题、可用性和原生文件选择器回调。菜单可用性与实际调用都读取已挂载输入框当前的附件接收策略。输入框卸载或锁定后该动作不可用，插件 dispose（资源释放）时移除注册。回调绑定留在输入模块内部。
 
+输入框通过会话作用域的 `useAccess` 钩子读取所在 Session 的访问答案：访问快照不含 `session/prompt` 时隐藏发送，不含 `session/cancel` 时隐藏停止，附件接收跟随 `fileUploads/upload`。没有 Session 的输入框尚无答案，保留普通控件。停止与附件接收在调用时重新读取当前答案。这些界面判断不替代 Host 授权。

 `SessionInputShell` 通过私有 [DraftEditorRuntime](src/client/input/editor/runtime.ts) 为每个 Session 持有一个 Lexical editor，同时保留提交、附件选择和恢复决策。[DraftEditor](src/client/input/editor/DraftEditor.tsx) 呈现借用的 editor；InputBar 保留钩子与 refs，并通过 [view-binding](src/client/input/editor/view-binding.ts) 安装 DOM 行为。编辑器类型位于 [draft-editor.ts](src/client/contract/draft-editor.ts)，共享输入和提交类型位于 [input.ts](src/client/contract/input.ts)。编辑器后台更新会保留草稿选区，不修改文档选区或从其他控件夺回焦点；显式聚焦 Composer 时恢复其选区。这一拆分不支持同一 Session 同时挂载多个可编辑 root；[两阶段隔离提案](../../../.agents/notes/proposed/architecture/2026-09-14-composer-model-and-draft-editor.zh.md) 定义剩余工作。
 
 草稿中的普通文字及文件、目录、Session 引用胶囊在切换 Session 和刷新后保留。公开输入方法接受文本；内部恢复和工作区携带保留结构化引用。输入模型在首次对外读取前导入保存内容；React 只挂载同一编辑器并绑定现有 Conversation store 写入回调。原存储 key 兼容旧字符串，新写入保存不含运行时节点 ID 的语义快照。等待 skill 目录不会阻塞编辑：斜杠名称保持普通文字，直到匹配的目录项到达。目录到达只重匹配当前文字，不改变胶囊、选区或 Undo 历史。浏览器持有的附件 File 对象不由这一机制持久化。[草稿初始化决策](../../../.agents/notes/implemented/architecture/2026-09-30-structured-draft-initialization.zh.md)规定所有权与恢复流程。

 The Web `standard`, `ptc`, and `cordis` presets expose `present` for final files accessible through the Session filesystem, including files created through Bash. Call it with `files: [{ path, description? }]` after creating the files. The [present tool](../../deliverables/deliverable-file-references/README.md) owns file-count limits and Session declarations. A single delivery fills the row; multiple deliveries form a two-column grid, collapsed after four files. Cards show the basename, description or file type, and a shared native opening control. Delivery and changed-file icon tiles use white at 50% opacity in the light theme and 5% in the dark theme. Icon tiles and single-file changed cards use the same border as delivery cards. Clicking the card previews the file in the right Sidebar. The control opens the default application and lists associated applications, with file reveal last. Matching inline-code references also open Sidebar previews. Delivery cards appear in the turn tail only after the turn ends, so a turn waiting on a blocking question shows none yet; the `present` tool description directs the model to link files in its message for earlier review. Cards include every declaration in the turn, including declarations recorded after the closing reply; duplicate declarations use the last description.
 
-The `present` tool row retains its document icon and recorded result across progress, success, failure, and interruption. Native actions share pending state and publish progress or retryable errors on the card. Successful open or reveal feedback stays visible for five seconds, fades over 200ms, then restores the file description; failures remain visible until another attempt. Desktop metadata is loaded when cards mount and invalidated on connection replacement. Without a Host desktop, cards retain Sidebar preview but omit native controls; failed metadata reads offer Retry. Delivery cards and change review expose `deliverables.file.actions` and `deliverables.review.file.actions`, supplied by [ui-open-in-app](../ui-open-in-app/README.md). Association GET requests and native POST actions both validate the recorded file coordinates and Session filesystem mapping before using the Host desktop.

Subject: [PATCH 04/42] feat(api): re-check prompt access and name fork
 children

The Gateway admits a prompt before the controller sees it, so a binding narrowed while the prompt waited must not still deliver: the Remote method passes a predicate that re-reads the caller's access after every await and immediately before delivery, and cancel re-reads it in the same synchronous step. One requestId still produces one message; a retry from another principal is refused as session/request-conflict. Fork callers may name childSessionId so an interrupted attempt resumes the child it stored; any other occupant of that id is refused as session/fork-conflict. The agent-controller admission pipeline this previously built on is not part of the current master, so the prompt keeps the direct admission path and the tool-execution turn carrier is gone.

Subject: [PATCH 05/42] test(api): cover the prompt access recheck and the
 named fork paths

Close the Session Controller's remaining per-file coverage debt: a named
fork adopting the child its earlier attempt stored, refusing a name another
Session holds or one seeded at a different cut, and the named-child
observation failures; prompt admission sharing one in-flight requestId and
refusing a duplicate from another caller; the retry read from a drained
splice; the access-withdrawn and aborted-admission delivery paths; cancel
after the caller's grant is gone; and the Assistant settlement that appends
past the last entry. Test-only: no production behavior changed.

Subject: [PATCH 06/42] docs(ui-workspace): state the connectWorkspace contract
 once

The model-visible catalog inherited two versions of the same JSDoc sentence,
one of which contradicted the other. Describe the blank reuse once: the first
reusable listed blank, the requested preset or its default, one shared attempt
per Workspace and preset. The generated client inspect catalog follows.

Subject: [PATCH 07/42] refactor(ui-conversation): keep the notice store off
 the published SessionInput

The composer notice store has no production reader through the published
SessionInput seam: the bar renders it through ComposerBarInjected.hooks.notices
and the only other reader was a test. Leave the store on SessionInputShell,
which the hook wiring uses, and assert the bar's hook in the Chat spec so the
contract surface only publishes members with real consumers.

Subject: [PATCH 08/42] refactor(ui-conversation): make the composer
 file-intake hook optional

A bar registration that cannot prove live file-intake permission omits the
source; the bar then offers no file controls, matching the no-session
placeholder's fail-closed answer. PropsHooks keeps required hook seats intact
and lets an optional source leave its seat undefined.

Subject: [PATCH 11/42] refactor(ui-workspace): own the branch naming and
 listed presentation

The published UiWorkspace no longer requires openListedBranch: that wait is an
internal navigation helper, and the service forkSession takes the branch
boundary and presentation choice as optional inputs. The Chat branch surface
now supplies only its branch point and analytics and lets Workspace navigation
decide whether the child may be named and when it becomes presentable.

Subject: [PATCH 12/42] refactor(session-controller): drop the prompt
 pre-delivery access recheck

The Gateway already admits each call; P1 no longer re-reads the caller's access
after prompt admission. Cancellation still refuses delivery when the caller
aborts during admission, and the requestId dedup/conflict, cancel recheck, and
fork naming behavior stay. The README pair follows.

Subject: [PATCH 13/42] fix(session-controller): finish the Workspace attach a
 named fork left pending

A first attempt that materialized the child and then failed at attachSession
was reported as failed, but its retry adopted the stored child and returned
success before attaching it, leaving the child ungrouped. The adoption path now
completes the missing attach and reports the same session/workspace-attach-failed
if that still rejects.

Subject: [PATCH 14/42] fix(session-controller): ask the concrete access
 decision before cancelling

The recheck used allows(), the list-filter view that never sees call arguments,
so a policy narrowing cancel to args.request refused a legitimate caller as
access-withdrawn forever. Ask decide() with the principal and the request, keep
the policy's own refusal reason, and cover both an args-independent role and an
args-dependent condition.

Subject: [PATCH 17/42] fix(ui-conversation): gate the fixed stop shortcut
 through the shared stop

The button re-read the live session/cancel answer but the fixed shortcut
received the raw stop, so a withdrawal still sent Esc-Esc cancellation. Build
one gated stop used by both entry points and cover the shared gate.

Type the tracked binding disposers by their real shape and let a disposed

Subject: [PATCH 19/42] revert(session-controller): restore the package to
 master

P1 keeps only the client/host extension seams; the requestId deduplication,
the cancel recheck, and the named fork child are deferred to a later change.
The package, its README pair, and the persistence schema lines return to the
master state, so the branch adds no session-controller behaviour.

Subject: [PATCH 20/42] fix(ui-chat): narrow the injected Chat View without an
 unknown assertion

Read the slot injection through its real rest-parameter function type and invoke it directly, so the static gate sees no new assertion to unknown. The client inspect catalog's expected uiWorkspace signature follows the generated catalog after the fork options became ForkSessionOptions.

Subject: [PATCH 21/42] fix(client): keep the served-page records on the master
 access API

The owner-baseline gating commits are superseded by master's whenAccess seams,
so the remaining records revert to the master shapes: the deliverables opener
takes no owner answer, the Japanese dictionaries carry the surviving copy, and
the test splice and owner assertions match the current services.

Subject: [PATCH 22/42] refactor(client): read composer access through
 useAccess and drop the branch-refusal notice

- The composer decides file intake from the Session-scope useAccess('fileUploads/upload')
  answer, like Send and Stop. The optional fileIntake hook seat, the InputHub fileIntake
  entries, and the ui-slots optional-hook typing are removed.
- The fixed Stop shortcut no longer re-reads session/cancel through a shared stop; the
  button stays hidden by useAccess and the Host refuses a withdrawn cancel.
- uiConversation.noticeBranchRefusal, branch.ts, ForkRefusal, and message.branchRefused are
  removed; a failed Chat branch leaves the source view unchanged, as on master.

 ## Write actions
 
-The Turn Tail branch action reads the Session-scope `useAccess('session/fork')` Hook and disappears while the calling Peer's access snapshot excludes that endpoint; the view always receives the `forkAt` handler. A branch names its child only while the snapshot includes `session/rename` for the source Session; otherwise the child keeps the Host's title and opens once the Session list carries it. A branch the Host refuses states why, on the Session it was asked of, through the composer's notice channel, as the Host's own message with the stable code beside it. The Session tree's branch verb shares the refusal notice and the rule for naming and opening a branch. These answers never replace Host authorization.

Unmounting or locking the composer disables that action; disposing the plugin removes its registration. The callback binding stays inside the input module.

 `SessionInputShell` owns one Lexical editor per Session through its private [DraftEditorRuntime](src/client/input/editor/runtime.ts), while retaining submission, attachment selection, and recovery decisions. [DraftEditor](src/client/input/editor/DraftEditor.tsx) renders the borrowed editor; InputBar retains its Hooks and refs and installs DOM behavior through [view-binding](src/client/input/editor/view-binding.ts). Editor-facing types live in [draft-editor.ts](src/client/contract/draft-editor.ts), with shared input and submission types in [input.ts](src/client/contract/input.ts). Background editor updates retain the draft selection without changing the document selection or reclaiming focus from another control; explicit Composer focus restores its selection. This separation does not support simultaneous editable roots for one Session; [the two-stage isolation proposal](../../../.agents/notes/proposed/architecture/2026-09-14-composer-model-and-draft-editor.md) defines the remaining work.

Subject: [PATCH 23/42] refactor(client): drop owner-era leftovers and gate
 sidebar New Session on session/create

- The Conversation binding tracking returns to master: the retainInfo subscription and the
  plugin-owned binding effects are a separate fix, not a served-page seam.
- The deliverables opener drops the ownerHostRoutes parameter no caller passes any more.
- Assertions on existing connection and HMR behavior, the menu-open-state spec, and the
  settings-general roster splice return to master.
- Workspace shortcuts no longer re-read Session access through source(); the Host refuses a
  denied rename, fork, or archive.
- The sidebar New Session button, the window-chrome New Session control, and the expanded
  brand shortcut render only while useRemoteAccess('session/create') allows it.

 ### Brand and New Session
 
-The expanded brand row renders `sidebar.brand.mark` and `sidebar.brand.name` as independent single slots; the collapsed rail renders the same mark slot. On Web and Windows desktop, clicking the expanded brand starts a new session; hovering or focusing it shows no tooltip. Without occupants, the shell uses the fish mark and a localized local-build label. A complete build stacks a code badge below the label as `version[-commit][-dirty]`, using `DSH_CLIENT_VERSION`, the optional 7-character `DSH_CLIENT_COMMIT_HASH`, and `DSH_CLIENT_GIT_DIRTY=true`; missing version metadata omits the badge. Clicking the fallback mark or label of such a build copies that badge text instead of starting a session, also on macOS desktop, and a successful write shows a Version copied toast. New Session targets the explicit Workspace used by a scoped action, otherwise the current Session's Workspace, otherwise the most recently active Workspace; when none exists it clears into the blank New Session page. The expanded New Session button displays the effective binding as trailing grey text on keyboard focus regardless of hover capability, and on hover when the device supports it. While the shortcut is visible, the centered icon and label fade before it when space is narrow; CSS reserves the shortcut’s width without measuring the button. Icon-only controls retain tooltips with platform-formatted keycaps, including the resident macOS header control when the sidebar is hidden. All controls expose `aria-keyshortcuts`.

Subject: [PATCH 24/42] fix(ui-workspace): keep the per-resource access gates
 on the whenAccess client

Master's rows and menus carry no answer of their own, so the served-page seams
thread the Slot-standard access Hooks through the workspace browser and the
session actions: New Session, workspace rename/delete/reorder, and a Session's
rename, pin, archive, and reorder appear only while their own resource allows
them. The rows spec keeps master's pointer-armed rename helper and supplies the
allow-all answers as props.

Subject: [PATCH 25/42] chore(client): follow the merged seam records in
 generated artifacts

The client inspect catalog follows the seam signatures, the unknown-cast
baseline drops the two casts this branch retired, and the README pairing
records match the merged prose.

 The Web `standard`, `ptc`, and `cordis` presets expose `present` for final files accessible through the Session filesystem, including files created through Bash. Call it with `files: [{ path, description? }]` after creating the files. The [present tool](../../deliverables/deliverable-file-references/README.md) owns file-count limits and Session declarations. A single delivery fills the row; multiple deliveries form a two-column grid, collapsed after four files. Cards show the basename, description or file type, and a shared native opening control. Delivery and changed-file icon tiles use white at 50% opacity in the light theme and 5% in the dark theme. Icon tiles and single-file changed cards use the same border as delivery cards. Clicking the card previews the file in the right Sidebar. The control opens the default application and lists associated applications, with file reveal last. Matching inline-code references also open Sidebar previews. Delivery cards appear in the turn tail only after the turn ends, so a turn waiting on a blocking question shows none yet; the `present` tool description directs the model to link files in its message for earlier review. Cards include every declaration in the turn, including declarations recorded after the closing reply; duplicate declarations use the last description.
 
-The `present` tool row retains its document icon and recorded result across progress, success, failure, and interruption. Native actions share pending state and publish progress or retryable errors on the card. Successful open or reveal feedback stays visible for five seconds, fades over 200ms, then restores the file description; failures remain visible until another attempt. Desktop metadata is loaded when cards mount and invalidated on connection replacement; a page whose injected access baseline is not the owner's issues no such read, so its cards keep the Sidebar preview and their unavailable fallback, and the native controls and the owner-only reads behind them stay off. Without a Host desktop, cards retain Sidebar preview but omit native controls; failed metadata reads offer Retry. Delivery cards and change review expose `deliverables.file.actions` and `deliverables.review.file.actions`, supplied by [ui-open-in-app](../ui-open-in-app/README.md). Association GET requests and native POST actions both validate the recorded file coordinates and Session filesystem mapping before using the Host desktop.

Subject: [PATCH 28/42] feat(ui-session): answer Session access for JS callers

The Session kind owns its remoteAccess source, so other plugins get one
non-Hook read from this service instead of reading the source themselves.
Navigation uses it for the branch-naming answer.

 ## Access Hooks
 
-The package injects the Client `remoteAccess` service and publishes Session access Hooks over its `source()`: the root `useSessionAccess(sessionId, action)` answers on one Session resource, and the Session-scope `useAccess(action)` answers on the bound Session's resource; the `global` resource's answer is a different Hook, `useRemoteAccess(action)`, so neither shadows the other. `ctx.uiSession.whenAccess(sessionId, action, callback)` is the JS counterpart of `useSessionAccess`: it keeps the callback's effects installed while the current Peer may call `action` on that Session, with the semantics of `ctx.remoteAccess.whenAccess`. The SessionMaybe-scope `useAccess(action)` returns `undefined` while no Session is bound, which callers treat as not allowed; a decision on the `global` resource reads `useRemoteAccess` instead. Snapshot semantics belong to [`dsh-api-remote-access`](../../api/remote-access/README.md#client-face).

Subject: [PATCH 29/42] fix(ui-workspace): route row gates through the Session
 service

Read the branch-naming answer through uiSession.access instead of the
cross-kind source, drop the unused openListedBranch method, give the branch
list refresh its own notice, and gate the search result restore control like
the archive row. The forkSession contract now states its navigation and throws
behaviour, present documents its 2x2 landing table, and the README describes
the real branch policy and row gating.

A page whose access snapshot includes `session/rename` may name the child — `selected` opens it immediately while `listed` leaves the selection alone. A page without that answer cannot name the child: the child keeps the Host's title, one navigation begins for the branch, and the child opens once the Host lists its summary, so the source view stays until then. The optional synchronous preparation callback runs after the target is retained and only for a current Workspace request, so superseded requests do not move composer drafts. Navigation or owner disposal suppresses the late UI commit, not the underlying Session creation.
+
+Session and Workspace rows derive their affordances from the browser root's access Hooks: the global `useRemoteAccess('session/create')` gates every New Session entry, `useWorkspaceAccess` gates a Workspace's create, rename, delete, and reorder verbs, and `useSessionAccess` gates a Session row's rename, fork, drag, pin, archive, and unarchive verbs plus the search result's restore control. A refused verb is not rendered, while every Host request remains authoritative; `ctx.uiSession.access(sessionId, action)` answers the same Session question for JS callers outside render. Startup restoration retains its main reference without changing the selected panel or cancelling a later navigation. Archiving the main Session releases its reference and clears the main selection. Selection failure leaves a global panel visible. Session rows read `usePanelInfo` to suppress their selected appearance while a global panel is active; search and directory-picker focus alone do not leave that panel.
 
 Navigation and startup restoration obtain the selected Session's projections from its `follow`; neither issues a separate projection refresh for that Session or its parent, except that restoring a saved blank first reloads that Session's projections, because listed values are cached hints that can lag its log after an unclean Host exit.

+Session 行与 Workspace 行的可用操作来自浏览器根的访问 Hook：全局 `useRemoteAccess('session/create')` 门控所有新建会话入口，`useWorkspaceAccess` 门控 Workspace 的新建、重命名、删除与排序动作，`useSessionAccess` 门控 Session 行的重命名、分叉、拖拽、置顶、归档与取消归档动作，以及搜索结果的恢复控件。被拒绝的动作不渲染，但每个发往 Host 的请求仍以其授权为准；`ctx.uiSession.access(sessionId, action)` 为渲染外的 JS 调用方回答同一个 Session 问题。启动恢复会 retain 主 reference，不改变已选面板，也不取消后续导航。归档主 Session 会释放其 reference 并清除主选择。选择失败时保留当前全局面板。Session 行读取 `usePanelInfo`，在全局面板活跃时不显示 Session 选中样式；仅把焦点移到搜索框或目录选择器不会离开该面板。
 
 导航和启动恢复通过所选 Session 的 `follow` 获取投影，不会另行刷新该 Session 或其父会话的投影；例外是恢复已保存的空白会话时先重新加载该 Session 的投影，因为列表中的值是缓存提示，Host 非正常退出后可能落后于其日志。

Subject: [PATCH 30/42] fix(ui-conversation): gate keyboard submission and stop

Enter, Mod+Enter, and accelerated queue steering now read the same prompt
answer as the Send button, and the fixed Esc-Esc sequence reads the live
session/cancel answer before it consumes a press. The composer locks for a
denied prompt, the README states both paths, and tests pin each gesture.

 The composer registers the File command action and owns its label, availability, and native file-dialog callback. Menu availability and invocation both consult the mounted composer's current attachment-intake policy. Unmounting or locking the composer disables that action; disposing the plugin removes its registration. The callback binding stays inside the input module.

+The composer reads its Session's access answers through the Session-scope `useAccess` Hook: Send disappears while the access snapshot excludes `session/prompt`, Stop while it excludes `session/cancel`, and file intake follows `fileUploads/upload`. A composer without a Session has no answer and keeps its ordinary controls. The same answers gate the keyboard paths: Enter, Mod+Enter, and accelerated Enter neither submit nor steer the queue while `session/prompt` is excluded, and Esc-Esc sends no cancel sequence while `session/cancel` is excluded. These UI answers never replace Host authorization.
 
 `SessionInputShell` owns one Lexical editor per Session through its private [DraftEditorRuntime](src/client/input/editor/runtime.ts), while retaining submission, attachment selection, and recovery decisions. [DraftEditor](src/client/input/editor/DraftEditor.tsx) renders the borrowed editor; InputBar retains its Hooks and refs and installs DOM behavior through [view-binding](src/client/input/editor/view-binding.ts). Editor-facing types live in [draft-editor.ts](src/client/contract/draft-editor.ts), with shared input and submission types in [input.ts](src/client/contract/input.ts). Background editor updates retain the draft selection without changing the document selection or reclaiming focus from another control; explicit Composer focus restores its selection. This separation does not support simultaneous editable roots for one Session; [the two-stage isolation proposal](../../../.agents/notes/proposed/architecture/2026-09-14-composer-model-and-draft-editor.md) defines the remaining work.

Subject: [PATCH 34/42] fix(ui-workspace): name every branch and open it on
 request

`increaseTitle` renames the child, not the source, and whoever may fork a Session also holds `session/rename` on the child it creates; the source's access answer therefore never decides the child's title. Remove the source-rename probe, the listed-branch wait, and its refresh-failure notice: `selected` opens the child immediately and `listed` leaves the selection alone. Update the public READMEs and the client API catalog.

-The Turn Tail branch action reads the Session-scope `useAccess('session/fork')` Hook and disappears while the calling Peer's access snapshot excludes that endpoint; the view always receives the `forkAt` handler. A branch names its child only while the snapshot includes `session/rename` for the source Session; otherwise the child keeps the Host's title and opens once the Session list carries it.

The optional synchronous preparation callback runs after the target is retained and only for a current Workspace request, so superseded requests do not move composer drafts.

A branch always names its child: whoever may fork a Session also holds `session/rename` on the child it creates. `selected` opens the child immediately, while `listed` (the default) leaves the selection alone. The optional synchronous preparation callback runs after the target is retained and only for a current Workspace request, so superseded requests do not move composer drafts. Navigation or owner disposal suppresses the late UI commit, not the underlying Session creation.
 
-Session and Workspace rows derive their affordances from the browser root's access Hooks: the global `useRemoteAccess('session/create')` gates every New Session entry, `useWorkspaceAccess` gates a Workspace's create, rename, delete, and reorder verbs, and `useSessionAccess` gates a Session row's rename, fork, drag, pin, archive, and unarchive verbs plus the search result's restore control. A refused verb is not rendered, while every Host request remains authoritative; `ctx.uiSession.access(sessionId, action)` answers the same Session question for JS callers outside render. Startup restoration retains its main reference without changing the selected panel or cancelling a later navigation. Archiving the main Session releases its reference and clears the main selection. Selection failure leaves a global panel visible. Session rows read `usePanelInfo` to suppress their selected appearance while a global panel is active; search and directory-picker focus alone do not leave that panel.

 Navigation and startup restoration obtain the selected Session's projections from its `follow`; neither issues a separate projection refresh for that Session or its parent, except that restoring a saved blank first reloads that Session's projections, because listed values are cached hints that can lag its log after an unclean Host exit.

 导航和启动恢复通过所选 Session 的 `follow` 获取投影，不会另行刷新该 Session 或其父会话的投影；例外是恢复已保存的空白会话时先重新加载该 Session 的投影，因为列表中的值是缓存提示，Host 非正常退出后可能落后于其日志。

Subject: [PATCH 35/42] revert(client): return the fork seam to master

ui-chat goes back to origin/master as a whole package: the footer branch forks
through ctx.sessions.fork with its own atSeq and analytics again, and Workspace
navigation takes no ForkSessionOptions. The package is identical to
origin/master, which drops the served-page branch assertions and README lines
added on this branch; they pinned behavior master already has.

ui-workspace restores master's forkSession signature and implementation
(allowMigration only, increaseTitle: true, selection untouched) and drops the
ForkSessionOptions type. uiSession leaves the inject list because the removed
session/rename probe was its only consumer. The row fork keeps passing
{ allowMigration: false }, which master already does, so forking from a shared
page never starts source-format migration.

Regenerate the client API catalog, restore the README fork contract (fork does
not navigate; allowMigration carries migration permission), re-record the
translation pairing, and return the ui-chat unknown-cast baseline count to 2.

Their official `MessageImages` entries call the shared root-scoped `conversation.images.content` Factory. Each position can be replaced independently without duplicating the gallery implementation.

It calls the shared `conversation.user.text` Factory for text and its own image Slot for images. Direct callers need a Session binding and supply their own row wrapper.

-The Turn Tail branch action reads the Session-scope `useAccess('session/fork')` Hook and disappears while the calling Peer's access snapshot excludes that endpoint; the view always receives the `forkAt` handler. A branch always names its child, because whoever may fork also holds `session/rename` on the child it creates, and it opens that child immediately. The Session tree's branch verb uses the same naming rule but leaves the selection alone. These answers never replace Host authorization.

Navigation or owner disposal suppresses the late UI commit, not the underlying Session creation.
 
 Session and Workspace rows derive their affordances from the browser root's access Hooks: the global `useRemoteAccess('session/create')` gates every New Session entry, `useWorkspaceAccess` gates a Workspace's create, rename, delete, and reorder verbs, and `useSessionAccess` gates a Session row's rename, fork, drag, pin, archive, and unarchive verbs plus the search result's restore control. A refused verb is not rendered, while every Host request remains authoritative. Startup restoration retains its main reference without changing the selected panel or cancelling a later navigation. Archiving the main Session releases its reference and clears the main selection. Selection failure leaves a global panel visible. Session rows read `usePanelInfo` to suppress their selected appearance while a global panel is active; search and directory-picker focus alone do not leave that panel.

Subject: [PATCH 36/42] revert(ui-conversation): leave a withheld submission to
 the Host

The access snapshot still withholds the Send button, Stop, and file intake, and
the Esc-Esc stop path still reads its own answer before sending a cancel. A
keyboard submission, however, once again reaches the Host, which refuses it and
reports the failure to the composer; gating that path needs a larger redesign
of the composer keyboard face.

 The composer registers the File command action and owns its label, availability, and native file-dialog callback. Menu availability and invocation both consult the mounted composer's current attachment-intake policy. Unmounting or locking the composer disables that action; disposing the plugin removes its registration. The callback binding stays inside the input module.
 
-The composer reads its Session's access answers through the Session-scope `useAccess` Hook: Send disappears while the access snapshot excludes `session/prompt`, Stop while it excludes `session/cancel`, and file intake follows `fileUploads/upload`. A composer without a Session has no answer and keeps its ordinary controls. The same answers gate the keyboard paths: Enter, Mod+Enter, and accelerated Enter neither submit nor steer the queue while `session/prompt` is excluded, and Esc-Esc sends no cancel sequence while `session/cancel` is excluded. These UI answers never replace Host authorization.
+The composer reads its Session's access answers through the Session-scope `useAccess` Hook: Send disappears while the access snapshot excludes `session/prompt`, Stop while it excludes `session/cancel`, and file intake follows `fileUploads/upload`.

Send is withheld from the button alone — a keyboard submission still reaches the Host, which refuses it and reports the failure. These UI answers never replace Host authorization.
 
 `SessionInputShell` owns one Lexical editor per Session through its private [DraftEditorRuntime](src/client/input/editor/runtime.ts), while retaining submission, attachment selection, and recovery decisions. [DraftEditor](src/client/input/editor/DraftEditor.tsx) renders the borrowed editor; InputBar retains its Hooks and refs and installs DOM behavior through [view-binding](src/client/input/editor/view-binding.ts). Editor-facing types live in [draft-editor.ts](src/client/contract/draft-editor.ts), with shared input and submission types in [input.ts](src/client/contract/input.ts). Background editor updates retain the draft selection without changing the document selection or reclaiming focus from another control; explicit Composer focus restores its selection. This separation does not support simultaneous editable roots for one Session; [the two-stage isolation proposal](../../../.agents/notes/proposed/architecture/2026-09-14-composer-model-and-draft-editor.md) defines the remaining work.

Subject: [PATCH 37/42] revert(ui-session,ui-conversation): let the stop
 shortcut reach the Host

A reviewer blocked the one-shot boolean access read the stop shortcut used:
the client should not expose a render-time access answer as a boolean API.
The Esc-Esc sequence submits its cancel again, and a Host refusal surfaces as
the composer failure the Stop button would have prevented. Send keeps the same
treatment: the access snapshot withholds the buttons, the Host refuses the
request, and the composer reports it.

 The composer registers the File command action and owns its label, availability, and native file-dialog callback. Menu availability and invocation both consult the mounted composer's current attachment-intake policy. Unmounting or locking the composer disables that action; disposing the plugin removes its registration. The callback binding stays inside the input module.
 
-The composer reads its Session's access answers through the Session-scope `useAccess` Hook: Send disappears while the access snapshot excludes `session/prompt`, Stop while it excludes `session/cancel`, and file intake follows `fileUploads/upload`.

 `SessionInputShell` owns one Lexical editor per Session through its private [DraftEditorRuntime](src/client/input/editor/runtime.ts), while retaining submission, attachment selection, and recovery decisions. [DraftEditor](src/client/input/editor/DraftEditor.tsx) renders the borrowed editor; InputBar retains its Hooks and refs and installs DOM behavior through [view-binding](src/client/input/editor/view-binding.ts). Editor-facing types live in [draft-editor.ts](src/client/contract/draft-editor.ts), with shared input and submission types in [input.ts](src/client/contract/input.ts). Background editor updates retain the draft selection without changing the document selection or reclaiming focus from another control; explicit Composer focus restores its selection. This separation does not support simultaneous editable roots for one Session; [the two-stage isolation proposal](../../../.agents/notes/proposed/architecture/2026-09-14-composer-model-and-draft-editor.md) defines the remaining work.

-The package injects the Client `remoteAccess` service and publishes Session access Hooks over its `source()`: the root `useSessionAccess(sessionId, action)` answers on one Session resource, and the Session-scope `useAccess(action)` answers on the bound Session's resource; the `global` resource's answer is a different Hook, `useRemoteAccess(action)`, so neither shadows the other. `ctx.uiSession.whenAccess(sessionId, action, callback)` is the JS counterpart of `useSessionAccess`: it keeps the callback's effects installed while the current Peer may call `action` on that Session, with the semantics of `ctx.remoteAccess.whenAccess`. `ctx.uiSession.access(sessionId, action)` answers the same question for a one-off read outside render; other plugins use that method rather than reading the Session kind's `remoteAccess.source()` themselves. The SessionMaybe-scope `useAccess(action)` returns `undefined` while no Session is bound, which callers treat as not allowed; a decision on the `global` resource reads `useRemoteAccess` instead. Snapshot semantics belong to [`dsh-api-remote-access`](../../api/remote-access/README.md#client-face).

with a statement parallel to the never-policy sentence, and refresh the
current-generation fixtures that persist it.
