Subject: [PATCH] feat(ui): add navigation entry customization (#6247)

* fix(ui): avoid tooltip trigger overlap when a side fits

* feat(ui): add navigation entry customization

* fix(test): keep tooltip geometry independent of JSX types

* fix(ui): align customization catalogs and integration fixtures

* test(ui): complete customization lifecycle and release integration coverage

* fix(ui): return entry discovery to the installed plugin list

* docs: refresh module graph for entry customization

* build: refresh workspace links for the moved entry customization package

* docs: regenerate catalogs and pairing hashes for the moved entry customization package

* test(web): cover default-loaded entry customization in the Web e2e

* test(ui): describe entry customization as a browser plugin in the host entry spec

* build: order entry customization publication files as workspace constraints require

* test(release): drop the moved entry customization package from the experimental family list

* style(ui): use the shared focus ring color on entry customization triggers

* test(web): re-record goldens for the default-loaded More navigation menus

* test(web): add the More conversation views trigger to the remaining CI-reported goldens

* docs: record region-owned pins for plugin entry customization

* refactor(ui): rebuild entry customization on region-owned pins and More menus

- Each navigation region (left sidebar, Conversation header, right sidebar
  guide) persists its own unpinned list under
  dsh.slot.manual-order.<list slot key>.v1, filters its own launchers, and
  draws its own More button and Menu around its actions slot.
- ui-entry-customization only registers the shared menu rows (entries with
  pin buttons, Browse other plugins, Create your plugin) into the three
  actions slots and keeps no state.
- Remove ctx.layout.entryVisibility, the plugin store, left-sidebar drag
  reordering, and agentPresetNavigation; ui-layout and ui-agent-preset match
  release/dsh-0.2.1 again.
- Keep the release <nav> and Conversation tab-bar visibility conditions.
- Move the More glyph into ui-primitives as IconAppsAddOutline{Regular,Medium}.

* docs: compile the entry customization owner props example

* docs(ui): describe the wrapping Conversation tab row in the header comment

* fix(ui): return New Session to the Workspace blank and its unsent draft

- New Session (startSession without options) takes the blank-reuse path
  again instead of creating a fresh Session on every call, which hid the
  previous blank and its unsent draft since a5c9c2aaeef (#5775).
- A request that names an Agent preset skips blanks listing a different
  preset, so Creator entries no longer take over an ordinary draft.
- Record the change in a v0.2.1-rc.2 upgrade guide; the Host refresh of a
  stale loaded blank stays deferred (see the Agent Note).

* docs: regenerate the Cordis inspect catalog for New Session blank reuse

* fix(ui): keep the selected entry visible while unpinned

- Left-sidebar rows and View tabs keep the selected entry, with aria-current or aria-selected, until another entry is selected.
- Entry menu Creator action takes no region argument; the registration's region selects the prompt.
- Document the 2px panel-row and 32px View-tab gaps; drop commit hashes from the New Session Agent Note.

* fix(ui): leave a blank of another preset unstaged when starting Creator

startCreatorDraft stages cordis only when the main blank lists no preset or already lists cordis; navigation opens a separate Creator blank otherwise, so a Standard draft blank keeps its preset.

* feat(ui): choose whether a draft prompt replaces, appends to, or keeps an existing draft

- DraftInitializationOptions gains whenDraftExists ('replace' | 'append' | 'keep', default 'keep'); clearPreviousDraft stays and maps to 'replace' only when whenDraftExists is omitted.
- Append adds the prompt as new paragraphs after the existing text and references; attachments stay in every mode.
- The three Create your plugin entries append their regional prompt.

* test(web): align e2e with New Session blank reuse and the visible selected entry

* refactor(ui): share the draft paragraph writer between setDraft and appendDraft

+# Agent Note: Plugin entry customization: region-owned pins and More menus
+
+Status: implemented
+
+English | [中文](2026-10-14-plugin-entry-customization.zh.md)
+
+## Problem
+
+The `release/dsh-0.2.1` Web app shows plugin entries in three regions: the left sidebar's panel buttons (`sidebar.panellist`), the Conversation header's View tabs (`conversation.view`), and the right sidebar guide's tool cards (guide entries from the right-sidebar tab registry). Each region shows every entry in registration order, so users cannot hide entries they rarely use, and every installed plugin makes the regions more crowded. Users also cannot browse more plugins or start creating a plugin from these positions.
+
+The feature ships in `release/dsh-0.2.1` and is later merged back to master with the release, so it changes as little as possible relative to the release: no changes to the slot framework (`ui-slots`, `ui-renderer`), no new Cordis service, `ui-layout` unchanged, and client plugin packages share only types ([Client package export rules](../../../../packages/client/AGENTS.md)). Persisted data must be readable without migration by a later slot-level store for manual order and pin state.
+
+## Decision
+
+Each region keeps and persists its own list of unpinned entries and filters its own entry buttons with it. Each region draws its own More button, opens a menu with the shared `Menu` component, and renders its actions slot inside that menu. The default-loaded plugin package `ui-entry-customization` registers the same menu-content component into the three actions slots: the entry list with pin buttons, Browse other plugins, and Create your plugin. This follows the Plugins page's Add plugin menu, where the page draws the button and menu and `ui-agent-preset` adds Create plugin through `plugins.add.actions`. Entries cannot be reordered.
+
+### User-visible behavior
+
+- The left sidebar, the Conversation header, and the right sidebar guide each have a More button. Its menu lists the region's customizable entries. Selecting an entry name opens the entry; its pin button shows or hides the entry in the region; the bottom of the menu has Browse other plugins (opens the Plugins main list) and Create your plugin (opens a new or reused blank Session with the Creator preset and fills in the region's prompt without sending it).
+- Entries appear in registration order, as in the release; they cannot be reordered.
+- Default entries always show and never appear in the menu: Plugins in the left sidebar, Chat in the Conversation header, and Files in the right sidebar.
+- Pin state survives page reloads and is shared by every Session.
+- Hiding the selected entry does not navigate away from its content; the left-sidebar row or View tab of the selected entry stays visible, as the current item, until another entry is selected.
+- The left-sidebar `<nav>` and the Conversation header tab bar keep their release visibility conditions: `<nav>` shows while any panel is registered, and the tab bar shows while more than one View is registered. Both conditions count registered entries, not entries left visible by pin state. With only Chat registered the tab bar stays hidden; with other Views registered, the tab bar and its More button stay visible even when every other View is hidden, so users can pin them again.
+- While an actions slot has no registrations, for example when `ui-entry-customization` is not loaded, its region shows no More button.
+
+### Structure and ownership
+
+```text
+ui-sidebar / ui-conversation / ui-sidebar-right (each region)
+  apply: the region's unpinned list (createSnapshotStore + persist) and setPinned
+         whether the actions slot has registrations (entriesOfSlot + subscribe)
+  root component: draws only fixed or pinned entries
+          while the actions slot has registrations, draws the region's More button and Menu:
+            <Menu anchor={region's More button} …>
+              renderSlot('<region>.actions', { entries, onOpen, onPinnedChange, onDismiss })
+            </Menu>
+
+ui-entry-customization (default-loaded)
+  registers one menu-content component into each actions slot (id 'entry-customization')
+  content: non-fixed entries with pin buttons, Browse other plugins, Create your plugin; keeps no state
+```
+
+Dependency direction: the three regions do not depend on the plugin package and only add uses of `client-store` and `ui-primitives` they already depend on. `ui-entry-customization` depends on the three regions (slot types) and on `ui-plugin-manager` and `ui-workspace` (service types), and calls `ctx.pluginNavigation` and `ctx.uiWorkspace` at runtime. No package gains a new runtime value import from another package.
+
+### Package changes relative to release/dsh-0.2.1
+
+| Package | Change |
+|---|---|
+| `ui-sidebar` | Adds `sidebar.panellist.actions`; apply adds the unpinned list, `setPinned`, and the actions-slot registration state; `SidebarRoot` filters entries and draws the More button and menu at the end of `<nav>`; expanded panel rows use a 2px gap instead of 4px |
+| `ui-conversation` | Adds `conversation.session.header.views.actions`; apply adds the same three parts; the Session header filters View tabs and draws the More button and menu inside the tab bar after the tablist; View tabs use a 32px gap instead of 36px, with 20px before More |
+| `ui-sidebar-right` | Adds `sidebar.right.tab.guide.actions`; apply adds the same three parts; the guide filters cards and draws the More card and menu after the cards; the guide registration declares the `sidebarRight` locale namespace |
+| `ui-entry-customization` (new package) | Registers the menu-content component into the three actions slots; owns the `entryCustomization` locale namespace; keeps no state |
+| `ui-plugin-manager` | Adds `openList()` to `pluginNavigation`: selects the Installed tab of the Plugins main list without opening a dialog or changing the current Session |
+| `ui-primitives` | Adds `minWidthFromAnchor` to `Menu` so the right-sidebar menu is never narrower than its card; adds `IconAppsAddOutlineRegular` / `IconAppsAddOutlineMedium` (`compact` for card size), shared by the left-sidebar and right-sidebar buttons |
+| `@deepseek-ai/dsh-web-app` | Loads `ui-entry-customization` by default |
+
+### Actions slots and menu content
+
+The three actions slots are root-scoped list slots declared by their regions and rendered inside the region's More menu. Other plugins may register menu items into them; items follow their registration `order`. Each region declares the owner props in its own contract (`SidebarPanelActionsOwnerProps`, `ConversationViewActionsOwnerProps`, `SidebarRightGuideActionsOwnerProps`) with the same fields; the left sidebar's type is:
+
+```ts
+interface SidebarPanelActionsOwnerProps {
+  /** The region's customizable entries in registration order; fixed entries are excluded. */
+  readonly entries: readonly { readonly id: string; readonly label: string; readonly pinned: boolean }[]
+  /** Open an entry without changing its pin state. */
+  readonly onOpen: (id: string) => void
+  /** Show (true) or hide (false) an entry. */
+  readonly onPinnedChange: (id: string, pinned: boolean) => void
+  /** Close the More menu. */
+  readonly onDismiss: () => void
+}
+```
+
+The `ui-entry-customization` menu-content component renders those fields: one row per entry (`EntryPickerRow`, whose name and pin button are separately focusable). Selecting the name calls `onDismiss` and then `onOpen`; the pin button calls `onPinnedChange`. Browse other plugins and Create your plugin follow and call `onDismiss` before acting. Each registration receives its region (used only to choose pin copy and the Creator prompt) and the two footer actions through its registration `inject`. Browse other plugins calls `ctx.pluginNavigation.openList()`; Create your plugin calls `ctx.uiWorkspace.startSession(undefined, { agentPreset: 'cordis', prompt, whenDraftExists: 'append' })` with the region's localized prompt. The call does not go through `ui-agent-preset`, so the preset chip plays no introduction animation. When no Creator preset exists, Session creation fails, Workspace shows its creation-failure notice, and no draft is created.
+
+The region decides its More button's styling, accessible name ("More", "More conversation views", and "More tools", from the regions' `panels.more`, `session.moreViews`, and `tab.guide.more` copy), Tooltip, and the menu's placement and width. Every menu uses the `ui-primitives` `Menu` component.
+
+### The three regions
+
+| | Left sidebar (`ui-sidebar`) | Conversation header (`ui-conversation`) | Right sidebar guide (`ui-sidebar-right`) |
+|---|---|---|---|
+| Entry source | Existing `panels` (from `sidebar.panellist`) | Existing View list (from `conversation.view`; Trajectory is removed while developer tools are off) | Existing tab registry `guide()` |
+| Entry id | Panel id | View id | `kind:entryId` |
+| Fixed | `plugins` | `chat` | Entries of kind `files` |
+| localStorage key | `dsh.slot.manual-order.sidebar.panellist.v1` | `dsh.slot.manual-order.conversation.view.v1` | `dsh.slot.manual-order.sidebar.right.tab.guide.list.v1` |
+| Actions slot | `sidebar.panellist.actions` | `conversation.session.header.views.actions` | `sidebar.right.tab.guide.actions` |
+| More button | Panel-button styling; shows its label when expanded and a Tooltip when collapsed | Small header button with a Tooltip | Card styling; the menu is at least as wide as the card and aligned to its end |
+| `onOpen` | `selectPanel(id)` | The Session's `selectView(id)` | Finds the entry by id, then `openTab(kind, { replaceTab: true })` |
+
+Each region defines its fixed entry in a module constant. The unpinned list is created in apply with client-store's `createSnapshotStore(…, { persist })`, is independent of Sessions, and stores `{ "unpinned": string[] }`. It reaches the region's root component through the inject `hooks.entryPins`; `setPinned` is an inject callback and ignores the fixed entry. Reads accept only an array of strings and treat any other value as an empty list, so corrupted localStorage content cannot break rendering. Ids that are no longer registered stay in `unpinned`, so an entry registered again stays hidden. Whether the actions slot has registrations reaches the root component through `hooks.entryActions`.
+
+Every localStorage key has the form `dsh.slot.manual-order.<list slot key>.v1`, named after the list slot that holds the entries rather than after the region package: the left sidebar and the Conversation header use the existing `sidebar.panellist` and `conversation.view`. The right-sidebar guide entries come from the tab registry and have no list slot in the release, so their key uses the name reserved for one, `sidebar.right.tab.guide.list`. A later slot-level store for the manual order and pin state of a list slot reads these keys and ids directly; saved `unpinned` values need no migration, and fields added later default to empty lists when absent from saved values.
+
+Right-sidebar ids use `kind` instead of `providerId`: when an extension takes over a kind, `providerId` changes while `kind` stays the same, so persisted pin state remains valid after the takeover.
+
+## Alternatives considered
+
+**Keep pin state in a Cordis service (provided by `ui-layout` or the plugin).** A region must read pin state while drawing its own buttons, and a slot only passes data from the region to the plugin, so plugin-held state needs a new public service. A `ui-layout` service would hold state unrelated to layout; a plugin-provided service would require each region to handle the service appearing and disappearing. Region-held state needs only a few lines.
+
+**One pin service per region.** Adds three public services with different signatures, while pin state is used only by its region and that region's menu.
+
+**Add `useSlotEntries` / `useManualOrderedListSlot` to the slot framework.** Requires changing `ui-slots` and `ui-renderer`, makes `ui-renderer` hold user preferences and read and write localStorage, and requires the right sidebar to mirror its guide entries into an internal list slot. Without reordering, each region's pin logic is a few lines, which does not justify changing the framework in a release.
+
+**Drag reordering in the left sidebar.** Only the left sidebar would use it, so the three regions would behave differently; this version does not support reordering.
+
+**Make the popover a Component Factory with the More button as a local slot.** The callers are the three regions and the implementation is the plugin. Declaring the Factory in the plugin package creates a dependency cycle, because the plugin's dependencies `ui-plugin-manager` and `ui-workspace` depend on the regions. Declaring it in `ui-layout` cannot name the plugin's locale namespace, so the declaration would be split across two packages and completed through declaration merging.
+
+**Let the plugin draw the whole More control (button and menu) from region data.** The plugin would copy the three regions' button styles, because CSS Modules cannot be reused across packages, and would need layout state from each region. Button styling carries region-specific behavior and belongs to the region.
+
+**Let the plugin render the region entries.** Left-sidebar icons and right-sidebar cards depend on their regions' child slots, and the plugin cannot reach the region's `renderSlot`; React nodes also cannot be passed as props.
+
+**Stop applying pin state while the plugin is not loaded.** The only benefit is that entries hidden before the plugin was disabled or failed to load would still show. That case requires explicitly disabling a default-loaded plugin; the limitation is accepted and documented in the README.
+
+**Show the tab bar based on entries left visible by pin state.** With other Views registered, hiding all of them would remove the tab bar together with its More button, and users could not pin them again.
+
+**Publish `agentPresetNavigation`, or have `ui-agent-preset` react to `startSession` calls that carry `agentPreset` and play the introduction animation.** The first adds a service only to forward to `startSession`; the second changes the `ui-workspace` and `ui-agent-preset` interfaces, and the introduction animation is not essential to this feature.
+
+**Name localStorage keys after region packages.** A later slot-level store keyed by list slot would have to migrate saved data.
+
+## Verification
+
+- Unit tests for the three regions cover: entry buttons show only fixed or pinned entries; `setPinned` ignores the fixed entry; `setPinned` writes and persists to the region's key; corrupted localStorage content reads as an empty list; ids that are no longer registered are kept; More shows while the actions slot has registrations and passes `entries` without fixed entries and the callbacks, and is absent without registrations; the Conversation header tab bar stays hidden with only Chat and stays visible after every other View is hidden; right-sidebar ids are `kind:entryId`.
+- Unit tests for the menu-content component cover: opening an entry, toggling a pin, an empty list showing only the footer actions, the arguments of Browse other plugins and Create your plugin, and removal of the three registrations when the plugin is released.
+- The Web e2e `entry-customization.e2e.ts` exercises the left sidebar through the real Web composition: More shows by default, hiding a panel removes its button, the panel still opens from the menu, it stays hidden after a reload, and pinning it again restores the button. Recorded-session Web goldens cover the Conversation header and right-sidebar More buttons; `changed-files-turn.e2e.ts` and `document-preview.e2e.ts` assert that the compact header has no tab bar with only Chat.
+- Every changed source file has 100% per-file coverage.

+- If a user hides entries and the plugin is later explicitly disabled or fails to load, the hidden entries stay hidden with no menu to restore them; re-enabling the plugin or clearing the region's localStorage key restores them.
+- localStorage is isolated by protocol, host, and port, so pin state is not shared after changing the Web port or between Web and Desktop.
+- client-store's persist does not validate restored values, so each region validates on read; the validation and the owner props type exist once per region.
+- The actions slots sit inside the More menus, so other plugins can add menu items but cannot place arbitrary controls beside the entries.
+- The right-sidebar key reserves `sidebar.right.tab.guide.list`; a later list slot for guide entries must use that name for saved pin state to carry over.
+- When an extension takes over a kind and uses different guide entry ids, existing pin state does not match the new entries.
+- With the plugin loaded by default, Web goldens that record the left navigation, the Conversation header tab bar, or the right sidebar guide include a More button.

+# Agent Note: 插件入口自定义：区域自管的 Pin 与“更多”菜单
+
+Status: implemented
+
+[English](2026-10-14-plugin-entry-customization.md) | 中文
+
+## 问题
+
+`release/dsh-0.2.1` 的 Web 应用在三个区域显示插件入口：左侧栏的面板按钮（`sidebar.panellist`）、会话头部的 View 标签（`conversation.view`）和右侧栏起始页的工具卡片（右侧栏 tab 注册表的 guide 入口）。三处都按注册顺序显示全部入口，用户不能收起不常用的入口，插件越多三处越挤；用户也不能在这些位置直接浏览更多插件或开始创建插件。
+
+该功能随 `release/dsh-0.2.1` 发布，之后随 release 合回 master，因此相对 release 的改动要尽量少：不修改 slot 框架（`ui-slots`、`ui-renderer`），不新增 Cordis 服务，`ui-layout` 保持不变，client 插件包之间只共享类型（[Client 包导出规则](../../../../packages/client/AGENTS.md)）。持久化的数据要能被以后在 slot 层统一保存手动顺序与 Pin 状态的实现直接沿用。
+
+## 决策
+
+三个区域各自保存本区域被收起入口的列表并持久化，用它过滤自己的入口按钮；各自画自己的“更多”按钮，用共用的 `Menu` 组件弹出菜单，菜单里渲染本区域的 actions slot。默认加载的插件包 `ui-entry-customization` 往三个 actions slot 注册同一个菜单内容组件：入口列表与 Pin 按钮、“浏览更多插件”和“创建你的插件”。做法与插件页的“添加插件”菜单一致：页面画按钮和菜单，`ui-agent-preset` 通过 `plugins.add.actions` 往菜单里加“创建插件”。不提供排序。
+
+### 用户可见行为
+
+- 左侧栏、会话头部、右侧栏起始页各有一个“更多”按钮，打开后的菜单列出该区域可自定义的入口。点入口名称打开它；点 Pin 让它在区域里显示或收起；底部有“浏览更多插件”（打开插件页主列表）和“创建你的插件”（用 Creator 预设新开或复用空白会话，填入该区域对应的提示语，不发送）。
+- 入口按注册顺序显示，与 release 一致；不提供排序。
+- 默认绑定的入口始终显示，不进入菜单：左侧栏的插件管理、会话头部的 Chat、右侧栏的文件。
+- Pin 状态在刷新页面后保留，所有会话共用。
+- 收起当前选中的入口不会切走当前内容；左侧栏行或 View 标签在选中其他入口之前保持显示，并标为当前项。
+- 左侧栏 `<nav>` 与会话头部标签条的显示条件与 release 一致：`<nav>` 在有已注册面板时显示，标签条在注册的 View 多于一个时显示。条件按已注册的入口计算，不按 Pin 后可见的入口计算，因此只有 Chat 时不显示标签条；有其他 View 时即使全部收起，标签条和其中的“更多”仍然显示，用户可以重新固定。
+- actions slot 没有注册项时（例如 `ui-entry-customization` 未加载），区域不显示“更多”。
+
+### 结构与职责
+
+```text
+ui-sidebar / ui-conversation / ui-sidebar-right (each region)
+  apply: the region's unpinned list (createSnapshotStore + persist) and setPinned
+         whether the actions slot has registrations (entriesOfSlot + subscribe)
+  root component: draws only fixed or pinned entries
+          while the actions slot has registrations, draws the region's More button and Menu:
+            <Menu anchor={region's More button} …>
+              renderSlot('<region>.actions', { entries, onOpen, onPinnedChange, onDismiss })
+            </Menu>
+
+ui-entry-customization (default-loaded)
+  registers one menu-content component into each actions slot (id 'entry-customization')
+  content: non-fixed entries with pin buttons, Browse other plugins, Create your plugin; keeps no state
+```
+
+依赖方向：三个区域不依赖插件包，只增加 `client-store` 与 `ui-primitives` 的既有用法；`ui-entry-customization` 依赖三个区域（slot 类型）、`ui-plugin-manager` 与 `ui-workspace`（服务类型），运行时通过 `ctx.pluginNavigation` 与 `ctx.uiWorkspace` 调用。各包之间不新增运行时值导入。
+
+### 各包改动（相对 release/dsh-0.2.1）
+
+| 包 | 改动 |
+|---|---|
+| `ui-sidebar` | 新增 `sidebar.panellist.actions`；apply 中新增 unpinned 列表、`setPinned` 和 actions slot 注册状态；`SidebarRoot` 过滤入口，并在 `<nav>` 末尾画“更多”按钮与菜单；展开态面板行间距由 4px 改为 2px |
+| `ui-conversation` | 新增 `conversation.session.header.views.actions`；apply 中新增同样三项；会话头部过滤 View 标签，并在标签条内、tablist 之后画“更多”按钮与菜单；View 标签间距由 36px 改为 32px，与“更多”间隔 20px |
+| `ui-sidebar-right` | 新增 `sidebar.right.tab.guide.actions`；apply 中新增同样三项；起始页过滤卡片，并在卡片之后画“更多”卡片与菜单；guide 注册声明 `sidebarRight` 文案命名空间 |
+| `ui-entry-customization`（新包） | 往三个 actions slot 注册菜单内容组件；`entryCustomization` 文案命名空间；不保存状态 |
+| `ui-plugin-manager` | `pluginNavigation` 增加 `openList()`：切到插件页主列表的“已安装”标签，不打开对话框，不改变当前会话 |
+| `ui-primitives` | `Menu` 增加 `minWidthFromAnchor`，让右侧栏菜单不窄于卡片；新增 `IconAppsAddOutlineRegular` / `IconAppsAddOutlineMedium`（`compact` 用于卡片尺寸），供左侧栏和右侧栏的按钮共用 |
+| `@deepseek-ai/dsh-web-app` | 默认加载 `ui-entry-customization` |
+
+### actions slot 与菜单内容
+
+三个 actions slot 都是 root 级 list slot，由各区域声明，渲染在本区域的“更多”菜单里，其他插件也可以往里注册菜单项，排列顺序按注册项的 `order`。owner props 由各区域在自己的 contract 中声明（`SidebarPanelActionsOwnerProps`、`ConversationViewActionsOwnerProps`、`SidebarRightGuideActionsOwnerProps`），三处字段相同，以左侧栏为例：
+
+```ts
+interface SidebarPanelActionsOwnerProps {
+  /** The region's customizable entries in registration order; fixed entries are excluded. */
+  readonly entries: readonly { readonly id: string; readonly label: string; readonly pinned: boolean }[]
+  /** Open an entry without changing its pin state. */
+  readonly onOpen: (id: string) => void
+  /** Show (true) or hide (false) an entry. */
+  readonly onPinnedChange: (id: string, pinned: boolean) => void
+  /** Close the More menu. */
+  readonly onDismiss: () => void
+}
+```
+
+`ui-entry-customization` 的菜单内容组件按上述字段渲染：每个入口一行（`EntryPickerRow`，名称与 Pin 按钮各自可聚焦），点名称先 `onDismiss` 再 `onOpen`，点 Pin 调 `onPinnedChange`；其后是“浏览更多插件”和“创建你的插件”，先 `onDismiss` 再执行。每个注册项通过 registration `inject` 得到所属区域（只用于选择 Pin 提示与创建提示语）和两个底部操作：“浏览更多插件”调用 `ctx.pluginNavigation.openList()`；“创建你的插件”调用 `ctx.uiWorkspace.startSession(undefined, { agentPreset: 'cordis', prompt, whenDraftExists: 'append' })`，`prompt` 按区域取本地化文案。该调用不经过 `ui-agent-preset`，预设标签不播放介绍动画；Creator 预设不存在时会话创建失败，Workspace 显示创建失败提示，不产生草稿。
+
+“更多”按钮的样式、无障碍名称（“更多”“更多会话视图”“更多工具”，分别来自各区域的 `panels.more`、`session.moreViews`、`tab.guide.more` 文案）、Tooltip、菜单的弹出方向与宽度都由区域决定；菜单外框统一使用 `ui-primitives` 的 `Menu`。
+
+### 三个区域
+
+| | 左侧栏（`ui-sidebar`） | 会话头部（`ui-conversation`） | 右侧栏起始页（`ui-sidebar-right`） |
+|---|---|---|---|
+| 入口来源 | 现有的 `panels`（来自 `sidebar.panellist`） | 现有的 View 列表（来自 `conversation.view`，未开启开发者工具时去掉 Trajectory） | 现有的 tab 注册表 `guide()` |
+| 入口 id | 面板 id | View id | `kind:入口id` |
+| fixed | `plugins` | `chat` | kind 为 `files` 的入口 |
+| localStorage 键 | `dsh.slot.manual-order.sidebar.panellist.v1` | `dsh.slot.manual-order.conversation.view.v1` | `dsh.slot.manual-order.sidebar.right.tab.guide.list.v1` |
+| actions slot | `sidebar.panellist.actions` | `conversation.session.header.views.actions` | `sidebar.right.tab.guide.actions` |
+| “更多”按钮 | 与面板按钮同样式；展开时显示文字，收起时显示 Tooltip | 头部样式的小按钮，带 Tooltip | 卡片样式，菜单不窄于卡片并右对齐 |
+| `onOpen` | `selectPanel(id)` | 本会话的 `selectView(id)` | 按 id 找到入口后 `openTab(kind, { replaceTab: true })` |
+
+每个区域用一个模块常量定义 fixed。unpinned 列表在 apply 中用 client-store 的 `createSnapshotStore(…, { persist })` 创建，与会话无关，值为 `{ "unpinned": string[] }`，经 inject 的 `hooks.entryPins` 交给区域根组件，`setPinned` 作为 inject 回调，对 fixed 入口不生效。读取时只接受字符串数组，其他值按空列表处理，避免损坏的 localStorage 内容影响渲染。`unpinned` 中已不存在的 id 保留，同一入口重新注册后保持收起。actions slot 是否有注册项经 `hooks.entryActions` 交给根组件。
+
+localStorage 键统一为 `dsh.slot.manual-order.<list slot key>.v1`，按入口所在的 list slot 命名，不按区域包命名：左侧栏与会话头部使用现有的 `sidebar.panellist`、`conversation.view`；右侧栏的 guide 入口来自 tab 注册表，release 中还没有对应的 list slot，键名使用为它预留的 `sidebar.right.tab.guide.list`。以后在 slot 层统一保存同一 list slot 的手动顺序与 Pin 状态时，直接沿用这些键和 id，已保存的 `unpinned` 不需要迁移；新增的字段在旧值中缺失时按空列表处理。
+
+右侧栏 id 使用 `kind` 而不是 `providerId`：扩展接管某个 kind 时 `providerId` 会改变，`kind` 不变，持久化的 Pin 状态在接管后仍然有效。
+
+## 考虑过的替代方案
+
+**由一个 Cordis 服务保存 Pin 状态（在 `ui-layout` 或插件中提供）。** 区域画自己的按钮时要读到 Pin 状态，而 slot 只能把数据从区域传给插件；由插件保存就必须新增公开服务。放在 `ui-layout` 会让布局服务承担与布局无关的状态；由插件提供时，区域还要处理服务时有时无。区域自己保存只需几行。
+
+**三个区域各提供一个 Pin 服务。** 新增三个形态不同的公开服务，而 Pin 状态只被所在区域和它的菜单使用。
+
+**在 slot 框架中提供 `useSlotEntries` / `useManualOrderedListSlot`。** 需要修改 `ui-slots` 与 `ui-renderer`，让 `ui-renderer` 持有用户偏好并读写 localStorage，右侧栏还要在内部同步成 list slot；不提供排序时，各区域的 Pin 逻辑只有几行，不值得为 release 修改框架。
+
+**左侧栏拖动排序。** 只有左侧栏使用，三个区域的交互不一致；本版本不提供排序。
+
+**把弹出框做成 Component Factory，“更多”按钮作为局部 slot。** 调用方是三个区域，实现方是插件：Factory 声明放在插件包会形成依赖环（插件依赖的 `ui-plugin-manager`、`ui-workspace` 依赖区域），放在 `ui-layout` 又引用不到插件的文案命名空间，只能把声明拆在两个包里用声明合并补齐。
+
+**插件画整个“更多”（按钮与菜单），区域只提供数据。** 插件要复制三个区域的按钮样式（CSS Module 不能跨包复用），并从区域取得布局状态；按钮样式带有区域的业务特点，应留在各自的区域。
+
+**由插件渲染区域入口。** 左侧栏图标和右侧栏卡片依赖各自的子 slot，插件拿不到区域的 `renderSlot`；ReactNode 也不能作为 props 传递。
+
+**插件未加载时停止应用 Pin 状态。** 唯一收益是插件在用户收起入口后被禁用或加载失败时，入口仍能显示；该情形需要显式禁用默认加载的插件，接受这一限制并在 README 中说明。
+
+**按 Pin 后可见的入口数决定标签条是否显示。** 有其他 View 时全部收起后，标签条和其中的“更多”一起消失，用户无法重新固定。
+
+**公开 `agentPresetNavigation`，或让 `ui-agent-preset` 响应带 `agentPreset` 的 `startSession` 并播放介绍动画。** 前者只为转调 `startSession` 新增服务；后者要修改 `ui-workspace` 与 `ui-agent-preset` 的接口，介绍动画不是本功能的必要部分。
+
+**按区域包命名 localStorage 键。** 以后在 slot 层按 list slot 统一保存时需要迁移已保存的数据。
+
+## 验证
+
+- 三个区域的单元测试覆盖：入口按钮只显示 fixed 或未收起的入口；对 fixed 入口调用 `setPinned` 不生效；`setPinned` 写入并持久化到对应键；localStorage 内容损坏时按空列表处理；已不存在的 id 被保留；actions slot 有注册项时显示“更多”并传入不含 fixed 入口的 `entries` 与回调，没有注册项时不显示；会话头部标签条在只有 Chat 时不显示，有其他 View 时全部收起后仍然显示；右侧栏 id 为 `kind:入口id`。
+- 菜单内容组件的单元测试覆盖：入口打开、Pin 切换、空列表时只有底部操作、浏览更多插件与创建插件的调用参数，以及三个注册项在插件释放后移除。
+- Web e2e `entry-customization.e2e.ts` 通过真实 Web 组合验证左侧栏：默认显示“更多”，收起后面板按钮消失，仍可从菜单打开，刷新后保持收起，重新固定后恢复。会话头部与右侧栏的“更多”由录制会话的 Web golden 覆盖；`changed-files-turn.e2e.ts` 与 `document-preview.e2e.ts` 断言只有 Chat 时紧凑头部没有标签条。
+- 改动的源文件逐文件覆盖率 100%。
+
+## 后果
+
+- 用户收起入口后，若插件被显式禁用或加载失败，被收起的入口保持隐藏且没有菜单可以恢复；恢复方式是重新启用插件或清除对应 localStorage 键。
+- localStorage 按协议、主机和端口隔离，更换 Web 端口或在 Web 与 Desktop 之间切换时 Pin 状态不共享。
+- client-store 的 persist 读回时不校验格式，三个区域各自在读取处校验；校验逻辑与 owner props 类型在三处各有一份。
+- actions slot 位于“更多”菜单内，其他插件只能往里加菜单项，不能在入口旁放置任意控件。
+- 右侧栏的键名预留了 `sidebar.right.tab.guide.list`；以后为 guide 入口新增 list slot 时必须使用这个名称，已保存的 Pin 状态才能沿用。
+- 扩展接管某个 kind 且使用不同的 guide 入口 id 时，原有 Pin 状态无法对应到新入口。
+- 插件默认加载后，录有左侧导航、会话头部标签条或右侧栏起始页的 Web golden 都会出现“更多”按钮。

+# Agent Note: New Session reuses a blank Session, matching a requested preset
+
+Status: implemented
+
+English | [中文](2026-10-20-new-session-blank-reuse-by-preset.zh.md)
+
+## Problem
+
+In 0.2.0-rc.2, New Session (the sidebar button, the Workspace "+" button, and the shortcut, all calling `uiWorkspace.startSession` without options) reused the Workspace's first blank Session. PR #5775, first released in `dsh-v0.2.1-alpha.2`, changed it to create a fresh Session and Agent on every call, so that New Session composes the current preset definition after the user changes one instead of keeping a reused blank's earlier composition ([upgrade guide](../../../../docs/upgrade-guide/v0.2.1-alpha.1/new-session-generations/guide.md)).
+
+A blank Session that is not current is hidden from the Session tree, and New Session is the only way back to it. After that change, a user who types a draft into a blank Session, switches to another Session, and clicks New Session lands in another empty Session; the original draft stays in localStorage under the old Session id, but no control returns to it. 0.2.1-rc.2 therefore loses New Session's unsent drafts.
+
+The Creator entries (`startSession(…, { agentPreset: 'cordis', prompt, clearPreviousDraft: false })`) also reuse the first blank Session and switch it to Creator: an existing ordinary draft stays under Creator mode and the Creator prompt is not filled in, and New Session can likewise take over a Creator blank.
+
+## Decision
+
+Only the Client (`ui-workspace`) changes; the Host is unchanged:
+
+- `startSession` without options takes the reuse path again and follows the same rule as `openWorkspace`, `connectWorkspace`, and `startSession` with options.
+- `createInWorkspace` names the first unstarted, unarchived blank Session that is still a Workspace member. A request that names a preset skips a blank whose listed preset (`projectionValues.agentPreset`) is a different one, while a blank with no listed preset remains eligible; a request without a preset may name any blank, which the Host switches to its default preset. The Host creates a Session when no blank is eligible.
+
+As a result, New Session returns to the original blank Session with its unsent draft, and preset flows such as the Creator entries do not take over a blank that lists another preset, so an ordinary draft is not moved under Creator. No persisted state is added, and the Client does not read the preset roster.
+
+## Alternatives considered
+
+**Revert the PR #5775 change completely, reusing the first blank for every request.** Drafts come back, but preset flows such as the Creator entries take over the blank holding the user's ordinary draft, switch it to Creator, keep the draft there, and cannot fill in their prompt.
+
+**Keep creating a fresh Session and move the abandoned blank's draft into it.** This needs rules for which blank to move from when several exist, how to treat attachments, and whether to archive the old Session, which is more change and state than reusing blanks.
+
+**Let a request without a preset reuse only a blank of the Host default preset.** The Client does not know the default preset and would have to request the `agentPresets.list()` roster.
+
+**Record a persisted source-to-blank-Session map in the Client.** It duplicates the preset each blank already records and must handle stale entries and per-origin isolation.
+
+**Clear the existing draft in place when the preset changes (`clearPreviousDraft: true`).** It deletes a draft the user was writing in the other mode.
+
+**Also change the Host to always call `presets.select` when reusing a loaded blank.** It fully keeps #5775's goal but is outside this Client-only fix; see Deferred work.
+
+## Verification
+
+- `ui-workspace` unit tests: New Session without options returns to the existing blank; a request without a preset reuses any blank, a request with a preset reuses only a blank listing the same preset, and a new Session is created when none matches. `navigation.ts` has 100% per-file coverage.
+- Regression localization: the same unit probe on the PR #5775 commit that made this change and on its parent, plus a browser reproduction on builds of both, confirmed that the draft loss comes from that change.
+
+## Consequences
+
+- New Session no longer guarantees the current preset definition: a reused blank whose Agent is still loaded in the Host with the same preset id keeps its creation-time composition; a blank resumed after a Host restart composes the current definition.
+- New Session may reuse a blank left by a preset flow such as the Creator entries; the Host switches it back to the default preset and its draft stays.
+- The [new-session-blank-reuse](../../../../docs/upgrade-guide/v0.2.1-rc.2/new-session-blank-reuse/guide.md) upgrade guide records the change relative to 0.2.1-rc.2.
+
+## Deferred work
+
+- Host `reuseLive` (`packages/api/session-controller/src/agent.ts`) returns the loaded Agent unchanged when the preset id matches and does not call `presets.select`. `select` decides whether a definition was registered again by comparing `Generation` objects: when they are the same it does nothing; when they differ it recomposes under the same Session id with the current definition and records `agent-preset/selected`; on a started Session it throws `agent-preset/locked`, and the caller creates a new Session instead. Removing the `target === current` early return and always calling `select` keeps drafts while meeting #5775's goal that New Session composes the current definition; it needs a Host test, and updates to the `reuseLive` JSDoc and to the upgrade guide's statement that the current preset definition is no longer guaranteed.

+# Agent Note: 新会话复用空白会话，指定预设时按预设匹配
+
+Status: implemented
+
+[English](2026-10-20-new-session-blank-reuse-by-preset.md) | 中文
+
+## 问题
+
+0.2.0-rc.2 中，新会话（左侧栏按钮、工作区“+”和快捷键，均调用不带选项的 `uiWorkspace.startSession`）复用工作区内第一个空白会话。PR #5775（首次发布于 `dsh-v0.2.1-alpha.2`）改为每次新建 Session 与 Agent，目的是在用户修改预设定义后，新会话按当前定义装配，而不是沿用复用空白会话的旧装配（[升级指南](../../../../docs/upgrade-guide/v0.2.1-alpha.1/new-session-generations/guide.zh.md)）。
+
+空白会话不是当前会话时不在 Session 树中显示，返回它的唯一入口是新会话。改为每次新建后，用户在空白会话中写下草稿、切到其他会话再点新会话，会进入另一个空的 Session；原草稿仍按会话 id 保存在 localStorage，但没有界面入口可以回到它。0.2.1-rc.2 因此丢失新会话的未发送草稿。
+
+此外，创造模式入口（`startSession(…, { agentPreset: 'cordis', prompt, clearPreviousDraft: false })`）复用第一个空白会话并把它切换到 Creator：已有普通草稿时，草稿留在 Creator 模式下，Creator 提示语不会填入；反之新会话也可能接管 Creator 的空白会话。
+
+## 决策
+
+只修改前端（`ui-workspace`），Host 不变：
+
+- 不带选项的 `startSession` 重新走复用分支，与 `openWorkspace`、`connectWorkspace` 和带选项的 `startSession` 使用同一规则。
+- `createInWorkspace` 在未开始、未归档、仍属于该工作区的空白会话中选第一个。请求指明预设时，跳过列出的预设（`projectionValues.agentPreset`）为其他值的空白会话，未列出预设的空白会话仍可用；请求未指明预设时任何空白会话都可用，由 Host 切换到默认预设。没有可用的空白会话时由 Host 新建。
+
+结果：新会话回到原来的空白会话，未发送的草稿保留；创造模式等预设流程不会接管列出其他预设的空白会话，用户的普通草稿不会被切到 Creator 下。不新增持久化状态，前端也不读取预设名单。
+
+## 考虑过的替代方案
+
+**完全回退 PR #5775 的这项改动，所有请求都复用第一个空白会话。** 草稿可以回来，但创造模式等预设流程会接管用户普通草稿所在的空白会话，把它切到 Creator，草稿留在 Creator 下，提示语也填不进去。
+
+**保持每次新建，把被丢下的空白会话中的草稿迁移到新会话。** 需要定义多个空白会话时迁移哪一个、附件如何处理、旧会话是否归档，改动和状态都比按预设复用多。
+
+**未指明预设的请求只复用 Host 默认预设的空白会话。** 前端不知道默认预设，需要额外请求 `agentPresets.list()` 名单。
+
+**在前端记录“来源 → 空白会话 id”的映射并持久化。** 与空白会话自身记录的预设重复，需要处理映射过期、按浏览器 origin 隔离等问题。
+
+**预设变化时在原会话上清空草稿（`clearPreviousDraft: true`）。** 会删除用户在另一种模式下写到一半的草稿。
+
+**同时修改 Host，让复用内存中的空白会话时总是调用 `presets.select`。** 能完整保留 #5775 的目的，但不在本次只修前端的范围内，见“推迟工作”。
+
+## 验证
+
+- `ui-workspace` 单元测试：不带选项的新会话回到已有空白会话；未指明预设时复用任何空白会话，指明预设时只复用列出相同预设的空白会话，没有时新建。`navigation.ts` 逐文件覆盖率 100%。
+- 回归定位：在 PR #5775 中做出这项改动的提交及其父提交上运行同一单元探针，以及在两侧构建上用浏览器复现，确认草稿丢失由该改动引入。
+
+## 后果
+
+- 新会话不再保证使用当前预设定义：复用的空白会话若其 Agent 仍在 Host 内存中且预设 id 相同，沿用创建时的装配；Host 重启后恢复的空白会话按当前定义装配。
+- 新会话可能复用创造模式等预设流程留下的空白会话，Host 把它切回默认预设，其中的草稿保留。
+- 升级指南 [new-session-blank-reuse](../../../../docs/upgrade-guide/v0.2.1-rc.2/new-session-blank-reuse/guide.zh.md) 记录相对 0.2.1-rc.2 的行为变化。
+
+## 推迟工作
+
+- Host `reuseLive`（`packages/api/session-controller/src/agent.ts`）在预设 id 相同时直接返回内存中的 Agent，不调用 `presets.select`。`select` 用定义的 `Generation` 对象是否相同判断定义是否重新注册过：相同则不做任何事；不同则在同一会话 id 上按当前定义重新装配并记录 `agent-preset/selected`；会话已开始时抛出 `agent-preset/locked`，调用方改为新建。去掉 `target === current` 的提前返回、改为总是调用 `select`，可以在保留草稿的同时满足 #5775“新会话按当前定义装配”的目的；需要配套 Host 测试，并更新 `reuseLive` 的 JSDoc 和上述升级指南中“不再保证当前预设定义”的说明。

+description: "New Session reuses a blank Session in the Workspace again instead of creating a fresh Agent on every call."
+---
+
+# New Session returns to its blank Session
+
+English | [中文](guide.zh.md)
+
+## Change
+
+In 0.2.1-rc.2, New Session in Web and Desktop, and `uiWorkspace.startSession(workspaceId)` without options, created a fresh Session and Agent on every call ([earlier guide](../../v0.2.1-alpha.1/new-session-generations/guide.md)). The blank Session it left behind is hidden from the Session tree, so its unsent draft could no longer be reached.
+
+New Session now reuses the first unstarted, unarchived blank Session in the Workspace, which the Host switches to its default preset, and creates a Session only when none exists. `startSession` with options, `openWorkspace`, and `connectWorkspace` follow the same rule; a request that names an Agent preset skips blanks whose listed preset is a different one, so preset flows such as the Creator entries do not take over another preset's draft.
+
+A reused blank whose Agent is still loaded keeps the preset composition it was created with. New Session no longer guarantees the current preset definition.
+
+## Migration
+
+1. After changing a preset definition, start the conversation in a Session whose Agent was composed after the change, for example by restarting the Host before using New Session; a blank resumed after a restart composes the current definition.
+2. Client integrations that must not take over a blank listing another preset pass `{ agentPreset }` to `startSession`, `openWorkspace`, or `connectWorkspace`.
+3. To confirm, type a draft after New Session, open another Session, and use New Session again: the same blank opens with the draft.

+## 变更

+在 0.2.1-rc.2 中，Web 和 Desktop 的新会话，以及不带选项的 `uiWorkspace.startSession(workspaceId)`，每次调用都创建新的 Session 和 Agent（[此前的指南](../../v0.2.1-alpha.1/new-session-generations/guide.zh.md)）。被留下的空白 Session 不在 Session 树中显示，因此其中未发送的草稿无法再回到。

+现在新会话复用工作区内第一个未开始、未归档的空白 Session，由 Host 切换到其默认 preset，没有空白 Session 时才创建。带选项的 `startSession`、`openWorkspace` 和 `connectWorkspace` 采用相同规则；指明 Agent preset 的请求会跳过列出其他 preset 的空白会话，因此创造模式入口等 preset 流程不会接管其他 preset 的草稿。
+
+被复用的空白会话若其 Agent 仍在加载状态，会保留创建时的 preset 装配。新会话不再保证使用当前的 preset 定义。
+
+## 迁移
+
+1. 更改 preset 定义后，在 Agent 于更改之后装配的 Session 中开始对话，例如先重启 Host 再使用新会话；重启后恢复的空白会话会按当前定义装配。
+2. 不能接管列出其他 preset 的空白会话的客户端集成，向 `startSession`、`openWorkspace` 或 `connectWorkspace` 传入 `{ agentPreset }`。
+3. 确认方式：新会话中输入草稿，打开另一个 Session，再使用新会话，应打开同一个空白会话并显示该草稿。

 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. Turning Coding Tools off while Trajectory is active returns to Chat; stored View preferences and recorded Session data remain intact. Turning it on makes Trajectory available again. View owners receive the available roster so their navigation actions can follow the same visibility.
 
+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.
+
 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.
 
 `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.

+
+## Summary
+
+Fill the More menus of the left sidebar, Conversation View tabs, and right-sidebar guide with each region's customizable entries, pin buttons, plugin browsing, and a reviewable Creator draft. The Web app loads it by default. Each region draws its own More button and stores its own pin choices; this package stores nothing.

+<a id="use-this-package"></a>
+## Use this package
+
+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.
+
+**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.
+

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+[`apply`](src/client/index.ts) registers [`EntryMenuContent`](src/client/EntryMenuContent.tsx) under id `entry-customization` into `sidebar.panellist.actions`, `conversation.session.header.views.actions`, and `sidebar.right.tab.guide.actions` through `ctx.slots.inject`, so each registration follows its region's declaration lifetime. The regions render these slots inside their own `Menu` and supply the entries, their pin state, `onOpen`, `onPinnedChange`, and `onDismiss` as owner props. The rows call `onDismiss` before opening an entry or running a footer action; pin changes leave the menu open.
+
+Each registration's `inject` supplies its region and two callbacks. Browsing calls `pluginNavigation.openList()`. Creation 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. The [`dsh-web-app` bundle patch](../../bundle/web-app/cordis.patch.yml) mounts the browser plugin.
+
+</details>
+
+-----
+
+<a id="model-experience"></a>
+## Model Experience
+
+None, as the package manages browser launchers and prepares an unsent, reviewable draft; only user submission sends its text to the model.
+
+#### KV Cache effect
+
+None; the package neither assembles nor sends model requests.
+
+## Known Limitations and Deferred Work
+
+<a id="known-limitations-and-deferred-work"></a>
+
+- If this package is disabled or fails to load after entries were unpinned, those launchers stay hidden and no More menu can restore them. Re-enable the package or clear the region's `dsh.slot.manual-order.*.v1` localStorage key.
+- Pin choices live in browser localStorage, which is isolated by protocol, host, and port: changing the Web port or switching between Web and Desktop does not carry them over, and they do not sync across devices.
+- **Create your plugin** does not check whether the Creator preset exists. Without it, Session creation fails, the Workspace shows its creation-failure notice, and no draft is prepared. Draft preparation also requires a resolvable Workspace; without one, the existing flow reports that a Workspace is required.
+- Entries keep registration order; the menus offer no reordering, and entries cannot move between regions.
+- Conversation controls follow the existing nonblank-Session header and Coding Tools eligibility. Right-sidebar controls require a selected Session and appear on its guide page.
+- Only active registered launchers appear; the menus are not an inventory of disabled or uninstalled plugins.

+
+## 概述
+
+为左侧栏、会话 View 标签和右侧栏起始页的“更多”菜单提供内容：各区域可自定义的入口、Pin 按钮、插件浏览与可审阅的创造模式草稿。Web 应用默认加载本包。各区域自己画“更多”按钮并保存自己的 Pin 状态；本包不保存状态。

+## 使用本包
+
+`@deepseek-ai/dsh-web-app` 组合包默认加载本包，无需在插件页开启或由 profile 选择。区域只在其 actions slot 有注册项时显示“更多”按钮，因此卸载本包会移除三个按钮。
+
+打开左侧导航入口下方的**更多**、会话 View 标签之后的**更多会话视图**，或右侧栏起始页卡片之后的**更多工具**。每个菜单按注册顺序列出该区域可自定义的入口；插件管理、Chat 和工作区文件始终显示，不列入菜单。点击入口名称会关闭菜单并打开该入口，不改变 Pin 状态。独立的 Pin 按钮在区域中固定或收起该入口，并保持菜单打开；实心 Pin 表示已固定。已收起的入口仍可从菜单打开，Pin 状态在刷新后保留。过长的入口名称会换行，更多工具菜单中则截断为单行。
+
+**浏览更多插件**进入插件页主列表，不打开安装弹窗。**创建你的插件**用 Creator 预设打开新 Session 或可复用的空白 Session，并把对应区域的简短本地化插件创建请求加入草稿：空草稿直接以该请求为文字，已有草稿保留其文字、引用和附件，请求另起一段追加在后面。它绝不发送消息。请自行审阅并发送草稿。当前区域没有可自定义入口时，两项操作仍然可用；空列表不添加分隔线。

+
+[`apply`](src/client/index.ts) 通过 `ctx.slots.inject` 以 id `entry-customization` 把 [`EntryMenuContent`](src/client/EntryMenuContent.tsx) 注册到 `sidebar.panellist.actions`、`conversation.session.header.views.actions` 和 `sidebar.right.tab.guide.actions`，每个注册项跟随所在区域声明的生命周期。各区域在自己的 `Menu` 中渲染这些 slot，并以 owner props 提供入口、Pin 状态、`onOpen`、`onPinnedChange` 与 `onDismiss`。菜单行先调用 `onDismiss`，再打开入口或执行底部操作；Pin 变化不关闭菜单。
+
+每个注册项的 `inject` 提供所属区域与两个回调。浏览调用 `pluginNavigation.openList()`。创建按区域取本地化提示语，调用 `uiWorkspace.startSession(undefined, { agentPreset: 'cordis', prompt, whenDraftExists: 'append' })`；该调用不经过 `ui-agent-preset`，预设标签不播放介绍动画。[`dsh-web-app` bundle patch](../../bundle/web-app/cordis.patch.yml) 挂载浏览器插件。

+## 模型体验

+无。本包管理浏览器入口并准备未发送、可审阅的草稿；仅用户提交才会将其文字发送给模型。
+
+#### KV Cache 影响
+
+无；本包既不组装也不发送模型请求。

+- 用户收起入口后，若本包被停用或加载失败，被收起的入口保持隐藏，且没有“更多”菜单可以恢复。重新启用本包或清除对应区域的 `dsh.slot.manual-order.*.v1` localStorage 键即可恢复。
+- Pin 状态保存在浏览器 localStorage，按协议、主机和端口隔离：更换 Web 端口或在 Web 与 Desktop 之间切换时不共享，也不跨设备同步。
+- **创建你的插件**不检查 Creator 预设是否存在。预设缺失时 Session 创建失败，Workspace 显示创建失败提示，不准备草稿。草稿准备还要求可确定目标 Workspace；没有目标时，现有流程提示需要 Workspace。
+- 入口保持注册顺序；菜单不提供排序，入口也不能跨区域移动。
+- 会话控件遵循现有非空 Session 头部与代码工作工具的可用性规则。右侧栏控件要求已选择 Session，并显示在其起始页。
+- 仅显示已激活、已注册的入口；菜单不是已停用或未安装插件的清单。

 The add control reuses `Button`, `Menu`, and `MenuItemButton`. Both installation actions call the same `openInstall` callback and use `InstallDialog` and `PluginManagerController`. The root-scoped list slot `plugins.add.actions` accepts contributed `MenuItemButton` rows after the install action; each contribution receives an `onDismiss()` callback to close the menu before starting its action.
 
+Other Client plugins can inject `pluginNavigation` and call `openList()` to select the Plugins main list, including when a detail page is already open. This browsing action preserves the current Session and opens no installation dialog. Installation remains an explicit action on the Plugins page.

 ### The store
 
 `PluginManagerController` owns the bundle views, busy keys, notices, install progress and the uninstall confirmation. Each read asks the inventory whether the Host manages a profile, then joins `listBundles` with `listPlugins` into one view per bundle, whose rows carry the live entry's enablement and fiber phase. It coalesces overlapping reads, refreshes after operations, on `plugin-manager/changed`, and on reconnect, and ignores late results after disposal. Install output is grouped by job id. The install dialog moves `idle → checking → starting → running → done | failed`, with `cancelling` and `applying` as the Host reports them and `unconfirmed` when an installation or cancellation response is lost; confirmed `applying` progress never regresses. Recovery uses `waitForInstall`, settling to `unknown` if no active request remains; checking and every active phase use ongoing, while the final screens use done or error. The check runs under an `AbortController` that going back or closing aborts, and its settlement is dropped; a run is stopped only through `pluginManager.cancelInstall`. Closing hides a run without discarding its state. A cancellation that overtakes installation is retried when progress or output acknowledges the request. A change the Host could not apply, a restart it waits for, and an override by a higher layer become toasts that retire on their own.

 The catalog above lists what each export is for; this section covers the behavior that props alone do not show. Product icon names omit artboard sizes and end in `Regular` for the supplied one-pixel artwork or `Medium` for the same geometry at a 1.3px stroke; the `size` prop controls rendered dimensions. Named components keep the chosen weight visible at import sites; the library owns stroke geometry instead of consumer CSS overrides. Each product, reference, link, and permission glyph intentionally keeps both weight exports even when the current product uses only one, so callers can choose emphasis without adding another API later; fill-only pairs render identically. `IconWarningOutlineRegular`/`Medium` use a circle; `IconWarningTriangleOutlineRegular`/`Medium` use a rounded triangle. `FishLogo` and `BrandWordmark` fill brand slots. `FileTypeIcon` renders the traditional 28px spreadsheet, folder, HTML, image, Markdown, generic, PDF, PPT, video, and Word glyphs, and uses the imported square technology artwork for the established 48 code and configuration categories. The import replaces artwork only: archive-only categories do not extend `CodeFileType`. `classifyFileType` applies exact filename, prefix, suffix, optional project-context, and extension rules in that order; React names win over TypeScript/JavaScript, Angular suffixes win over their base extension, and a Dart file becomes Flutter only when the supplied project files contain a `pubspec.yaml` with `flutter:`. Markdown and SVG remain traditional Markdown and image files. Spreadsheet mappings include CSV, TSV, Excel workbooks and templates, OpenDocument spreadsheets, and Numbers; KEY maps to slides, while RTF/ODT/Pages map to documents. `fileExtension` exposes the same basename and final-dot parsing for adjacent metadata labels. Traditional glyphs use a solid category-colored sheet with a white mark and translucent white corner; the generic code glyph uses angle brackets and a slash at the supplied 1.35px stroke; the generic file uses a grey sheet and darker grey corner. Callers may override the sheet color through `--dsh-file-type-icon-color`. The full-color technology artwork is the deliberate exception and retains its embedded palette. All glyphs are decorative and carry no label. `LinkIconMedium` is the leading glyph for clickable artifact links — globe, folder, code, image, document, or plain paper, and for a `url` link the mark of a well-known site named by its `href` — the developer sites a transcript usually cites (GitHub, GitLab, npm, PyPI, Stack Overflow, MDN, Wikipedia, Hacker News, YouTube, X, Bilibili, Zhihu, Juejin, CSDN) and mainstream search, video, social, shopping, and reference sites (Google, Baidu, DuckDuckGo, TikTok, Netflix, Spotify, Facebook, Instagram, Reddit, Telegram, WhatsApp, WeChat, QQ, Weibo, Taobao, AliExpress, eBay, Quora, V2EX, Apple) — while `classifyLinkPath` folds the shared file types into that existing six-category vocabulary. `ConnectionIndicator` renders a warning-colored disconnected action whose permanent retry glyph marks the retry action beside the owner-supplied outage label, the shared ongoing loader in the same warning color as its label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Clicking either warning state requests an immediate reconnect; no hover interaction changes the copy. The pill fades in on appearance, fades out for 150ms before unmounting, and sizes to its current label. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `useAnchoredPosition` and `useAnchoredMaxHeight` keep floating panels and bottom-anchored overlays clamped to the viewport and following their anchor; anchored overlays and portalled `Menu` add 20px to the frame's published top clearance, or keep 20px in native fullscreen, while preserving their own minimum margins in ordinary browsers. `HoverCard` keeps its portaled preview reachable across the anchor gap and can expose a copy button through the `copyText` prop. Its `preview` variant uses the anchor or `widthAnchorRef` element’s width minus 48px, centers the panel with 24px side insets, and places it above or below the row within the viewport. The panel keeps the frame’s top clearance, caps its height at 420px, and follows content and anchor resizing; Escape or pointer and keyboard activation of the anchor dismisses it. The whole preview fades in and out over 100ms; a closing preview stops receiving pointer input and unmounts after the fade. Re-entering the anchor during the fade restores it. Reduced-motion preferences suppress the transition. Copy labels are required only when copying is enabled. `HoverCard` and nested action tooltips display independently; use `Tooltip.portal` to layer the small bubble above the card. A visible nested `Tooltip` suppresses only its enclosing tooltip, not the hover card. `Toast` uses the owner's `holdMs` for both the fade delay and its hold-and-fade lifetime. Rerenders with unchanged `holdMs` do not restart that lifetime; completion uses the latest callback, and fully faded actions cannot receive input. A new component key restarts the banner. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order. Portalled `Menu` lists follow their anchor during dragging and CSS transforms, and stop tracking when closed. `Menu.autoFocus` focuses its first enabled item, supports Arrow Up/Down and Home/End navigation, and focuses the first button in the anchor on Escape; it is opt-in for action menus.
 
-`Tooltip` reads the anchor on hover or keyboard focus and fits its bubble from `ResizeObserver` border-box sizes. The bubble stays hidden until its first fit, slides inside the horizontal viewport margin, and flips above or below only when the opposite side fits. Label-size and viewport changes reuse the anchor coordinates; fitting does not synchronously measure the bubble or trigger a React render. Opt-in `openOnClick` also lets an informational button pin the same bubble for reading and associates it with the anchor description. Another click, Escape, Tab, or an outside pointerdown closes it; ordinary action tooltips still dismiss on click.
+`Tooltip` reads the anchor on hover or keyboard focus and fits its bubble from `ResizeObserver` border-box sizes. It stays hidden until its first fit, prefers the requested side, then tries the opposite and perpendicular sides, sliding along the anchor without covering it when a side fits. Horizontal placements keep a 10px gap; vertical placements use `gap` (8px by default). Width and height stay within a 12px viewport margin; text wraps, and content taller than the viewport scrolls when pinned. If no side fits, a stable viewport-bounded fallback can overlap the anchor. Viewport resize refreshes the anchor coordinates; label-size changes reuse them. Fitting does not synchronously measure the bubble or trigger a React render. Opt-in `openOnClick` also lets an informational button pin the same bubble for reading and associates it with the anchor description. Another click, Escape, Tab, or an outside pointerdown closes it; ordinary action tooltips still dismiss on click.

 上面的目录说明每个导出的用途；本节讲 props 本身看不出来的行为。产品图标名称不含画板尺寸，以 `Regular` 表示原始 1px 图形，以 `Medium` 表示同一几何的 1.3px 描边；`size` prop 控制渲染尺寸。具名组件让所选线重在导入处可见；描边几何由组件库拥有，而不是由消费方 CSS 覆盖。每个产品、引用、链接与权限图形都会有意保留两种线重导出，即使当前产品只使用其中一种，也让调用方无需再次扩展 API 就能选择强调程度；仅填充的成对图形外观相同。`IconWarningOutlineRegular`/`Medium` 使用圆形；`IconWarningTriangleOutlineRegular`/`Medium` 使用圆角三角形。`FishLogo` 与 `BrandWordmark` 填充品牌 slot。`FileTypeIcon` 渲染传统的 28px spreadsheet、folder、HTML、image、Markdown、generic、PDF、PPT、video 与 Word 图形，并为现有 48 个代码和配置类别使用导入的方形技术图形。该导入只替换图形：资源包中额外的类别不会扩展 `CodeFileType`。`classifyFileType` 按完整文件名、前缀、后缀、可选项目上下文、扩展名的顺序匹配；React 文件名优先于 TypeScript/JavaScript，Angular 后缀优先于基础扩展名，只有传入的项目文件包含带 `flutter:` 的 `pubspec.yaml` 时 Dart 文件才使用 Flutter。Markdown 与 SVG 仍分别使用传统 Markdown 与图片图形。表格映射包括 CSV、TSV、Excel 工作簿与模板、OpenDocument 表格和 Numbers；KEY 映射为幻灯片，RTF/ODT/Pages 映射为文档。`fileExtension` 为相邻元数据 label 暴露同一套 basename 与最终点号解析。传统图形使用实色分类底板、白色标记和半透明白色折角；通用代码图形使用尖括号与斜线，保留原图 1.35px 描边；通用文件使用灰色底板与较深灰色折角。调用方可通过 `--dsh-file-type-icon-color` 覆盖底板颜色。全彩技术图形是明确例外，会保留其内嵌调色板。所有图形都是装饰性的，不自带 label。`LinkIconMedium` 是可点击产物链接的前置图形——地球、文件夹、代码、图片、文档或纸张，`url` 链接的 `href` 指向已知站点时则改用该站点自己的标记——转写内容常引用的开发者站点（GitHub、GitLab、npm、PyPI、Stack Overflow、MDN、Wikipedia、Hacker News、YouTube、X、Bilibili、知乎、掘金、CSDN），以及主流搜索、视频、社交、购物与参考资料站点（Google、百度、DuckDuckGo、TikTok、Netflix、Spotify、Facebook、Instagram、Reddit、Telegram、WhatsApp、微信、QQ、微博、淘宝、速卖通、eBay、Quora、V2EX、Apple）——`classifyLinkPath` 把共享文件类型折叠进原有六类词汇。`ConnectionIndicator` 可渲染警告色的断联操作（常驻重试图形指明重试动作，断联文案由持有方提供）、与文案使用相同警告色的共享 ongoing loading 加一至三个点以独立于 retry 时序的 500ms 节奏推进的连接中状态，或成功色的恢复状态。点击任一警告状态都会请求立即重连；没有任何悬停交互会改变文案。药丸出现时淡入、卸载前淡出 150ms，宽度随当前 label 自适应。它的持有方提供可见性、恢复驻留时间、本地化 label 与立即重连回调；该原语不使用原生 title tooltip。`useAnchoredPosition` 与 `useAnchoredMaxHeight` 让浮动面板与底部锚定浮层始终钳制在视口内并跟随锚点；锚定浮层与 portal 模式的 `Menu` 在框架发布的顶部占用量上增加 20px，原生全屏时保留 20px，普通浏览器中沿用自身的最小边距。`HoverCard` 通过指针离开宽限期让采用 portal 的预览在跨过锚点间隙时仍可触及，并可通过 `copyText` prop 提供复制按钮。其 `preview` 变体使用 anchor 或 `widthAnchorRef` 元素的宽度减去 48px，左右各内缩 24px，并在视口内放置于行的上方或下方。浮层避开框架顶部保留区，高度最多 420px，会跟随内容及 anchor 尺寸变化；Escape 或通过鼠标和键盘激活锚点可将其关闭。整个浮层的淡入和淡出各持续 100ms；关闭中的浮层停止接收指针输入，淡出后卸载。在淡出期间移回锚点可恢复显示。减少动态效果偏好会禁用过渡动画。只有启用复制时才必须提供复制标签。`HoverCard` 与嵌套的操作提示独立显示；使用 `Tooltip.portal` 将小气泡置于卡片上层。可见的嵌套 `Tooltip` 只隐藏外层 tooltip，不隐藏悬停卡片。`Toast` 使用调用方的 `holdMs` 同时控制淡出延迟与停留加淡出的总时长。`holdMs` 未变时，父组件重渲染不会重启该生命周期；完成时调用最新回调，完全淡出的操作不能接收输入。新的组件 key 会重新开始横幅周期。`rankByName` 是 `/` 菜单命令源与 skill（技能）源共享的候选排序器：查询必须是名字的不区分大小写的有序子序列；前缀命中排最前，其次按对齐分数，再按来源顺序。 portal 模式的 `Menu` 列表会在拖动和 CSS 变换期间跟随锚点，并在关闭时停止跟踪。`Menu.autoFocus` 聚焦首个启用项，支持上下方向键与 Home/End 导航，并在 Escape 时聚焦 anchor 内的第一个按钮；操作菜单可显式启用。
 
-`Tooltip` 在悬停或键盘聚焦时读取锚点位置，再根据 `ResizeObserver` 提供的边框盒尺寸调整气泡。首次定位前气泡保持隐藏；横向移入视口留白，仅在另一侧容得下时上下翻转。标签尺寸与视口变化复用锚点坐标；定位不会同步测量气泡，也不会触发 React 渲染。 信息按钮可显式启用 `openOnClick`，点击后保持同一个气泡供阅读，并将内容关联为锚点的无障碍描述；再次点击、Escape、Tab 或外部 pointerdown 会关闭。普通操作按钮的 tooltip 仍在点击时关闭。
+`Tooltip` 在悬停或键盘聚焦时读取锚点位置，再根据 `ResizeObserver` 提供的边框盒尺寸调整气泡。首次定位前保持隐藏，优先使用指定方向，再尝试相反方向和垂直于该方向的两侧；只要某一侧容得下，就沿锚点平移而不遮挡锚点。左右放置保留 10px 间距，上下放置使用 `gap`（默认 8px）。宽高限制在视口内并保留 12px 边距；文本自动换行，超出视口高度的内容在固定气泡后可滚动。若所有方向都放不下，则使用稳定的视口内回退位置，可能遮挡锚点。视口尺寸变化会重新读取锚点坐标，标签尺寸变化则复用坐标；定位不会同步测量气泡，也不会触发 React 渲染。 信息按钮可显式启用 `openOnClick`，点击后保持同一个气泡供阅读，并将内容关联为锚点的无障碍描述；再次点击、Escape、Tab 或外部 pointerdown 会关闭。普通操作按钮的 tooltip 仍在点击时关闭。

 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.
+
 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.
 
 Default pages depend on the number of registered guide entries, not the number of tab types or open tabs. Exactly one entry opens its page directly; zero or multiple entries open the guide. Explicitly adding a guide still opens the guide, even with one entry. The sole docked guide is the only tab that cannot close; closing any other sole tab also collapses the column. The chip, context menu, and `close` API apply the same rule.

 每个 `guide` 入口具有 provider 内唯一的 `id`。开始页按当前生效的定义 id 渲染 `sidebar.right.tab.guide.entry`，传入入口 id、解析后的标题、可选描述，以及框架提供的 `useTabInfo` hook。provider 可按自己的定义 id 注册自定义卡片；未注册时使用默认图标与标题按钮。侧栏负责宽度和排列，自定义组件负责内部结构和交互。引导卡片统一使用 R20，包含悬停底色与提供方自有的分体按钮。排序或其他注册变化不会改变入口身份。无背景的快捷键文字右对齐。终端 Shell 菜单位于入口标题旁。
 
+root 作用域的 `sidebar.right.tab.guide.actions` list 有注册项时，引导卡片之后显示**更多工具**卡片。它的菜单与卡片末端对齐，不窄于卡片，并随菜单行增宽，最大为 480px 与视口宽度减 24px 中的较小值。菜单行为该 list 的注册项。每个注册项接收 `entries`（按注册表顺序的卡片，含 `id`、`label` 与 `pinned`；不含 kind 为 `files` 的卡片）、在引导页位置打开卡片标签类型的 `onOpen(id)`、`onPinnedChange(id, pinned)`，以及关闭菜单的 `onDismiss()`。引导页在浏览器 `localStorage` 的 `dsh.slot.manual-order.sidebar.right.tab.guide.list.v1` 下保存一份 root 级的已收起卡片 id 列表，每个 id 为 `kind:入口 id`，格式为 `{ "unpinned": string[] }`；该键名为以后的引导入口 list slot 预留。卡片由 kind 而不是提供方 id 标识，因此扩展接管某个 kind 且保持入口 id 时，Pin 选择仍然有效。kind 为 `files` 的卡片始终显示。收起只隐藏卡片，不关闭标签，也不改变标签类型注册或默认页。描述的显示密度按可见卡片数计算。未注册卡片的 id 保留在列表中；保存内容不是字符串数组时，所有卡片都显示。
+
 终端等需要独立实例的 tab 类型可声明 `multiple: true`。每次打开都会获得独立内容地址，因此移动和停靠会保留这些实例；普通页面仍在每个格内去重。
 
 默认页取决于已注册的引导入口数，不取决于 tab 类型数或已打开的 tab 数。恰好一个入口时直接打开对应页面；没有入口或有多个入口时打开引导页。即使只有一个入口，显式添加引导页仍会打开引导页。只有作为唯一停靠 tab 的引导页不可关闭；关闭其它任何唯一 tab 时会同时收起整列。chip、上下文菜单与 `close` API 使用同一规则。

 ### Global panel entries
 
-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. 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 registrations, neither the list nor spacing for it is rendered. The shipped composition registers no example panel.
+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.

+New Session, Workspace reopening, and explicit draft preparation name the first eligible blank in catalog order. A request that names a preset skips a blank whose listed preset is a different one, so a preset flow such as the creator entry does not take over another preset's draft; a request without a preset may name any eligible blank, which the Host switches to its default. A reused blank may keep the preset composition it was created with. Startup restoration names the saved blank. The Host reuses the named blank under the requested preset, or under its default when the request names none, and creates another Session when the blank has started, left the Workspace, or is held by another writer; navigation opens the returned Session without trying other blanks. `startSession` with draft options, `openWorkspace`, and `connectWorkspace` accept `{ agentPreset }` for a flow that knows its preset before it starts, such as the creator entry; a connection joins the latest in-flight connection to its Workspace only when both request the same preset, so the latest request always reaches the Host.

Released blanks retain their slash-command state when reused. Later navigation cancels a pending startup selection.
 
 Once both Workspace and Session startup baselines are ready, an empty installation calls `workspaces.initializeDefault` and creates or reuses its blank Session. The composer becomes editable when that Session is selected; no message is submitted automatically. Later navigation or owner disposal prevents startup from selecting its result. Ineligible first use leaves the folder picker available without an error. Default Workspace creation failure shows a transient notice directing the user to Choose workspace, and is not retried until the next startup. Session creation failures use the ordinary restoration error handling. The registered Workspace remains available if Session creation or later submission fails.

 The browser entry also declares two root-scoped `list` child seats on each Session row: `sidebar.session.row.leading`, rendered only while that row's primary status is idle and left blank on an archived row, and `sidebar.session.row.hover`, mounted only while that row's hover card is open. Both take the row's Session identity and nothing else, so an occupant reads its own data by that id; a Session-scoped seat would force a Session binding, which would activate and retain every listed Session.

+Client callers can pass `prompt`, `whenDraftExists`, and `clearPreviousDraft` in the second argument to `uiWorkspace.startSession`. A prompt is plain text; structured drafts are handled internally during restoration and Workspace transfer. An empty draft adopts the prompt. When the target already has text or attachments, `whenDraftExists: 'keep'` (the default) preserves them, `'replace'` replaces only the target Session's text and inline references with the prompt or clears them without one, and `'append'` adds the prompt as new paragraphs after the existing text; attachments stay in every case. `clearPreviousDraft: true` acts as `'replace'` only when `whenDraftExists` is omitted. Option values are captured before asynchronous creation and applied to the exact retained binding before navigation commits. Superseded navigation does not write content; a submission-blocked input refuses preparation and keeps the previous selection. Calls with or without options open the blank Session chosen as described above, so New Session returns to its unsent draft.
