 **A failed run is classified where the facts are.** `classifyInstallFailure` reads how the run ended and what pnpm printed — its `ERR_PNPM_*` codes and Node's errno names — into `packageResult.kind`. The client shows the kind as one line and folds pnpm's output behind the details. Parsing the log is confined to this one function with a fixture-driven test.
 
+**GitHub connection failures have a short budget before installation.** The Host runs a read-only `git ls-remote` check with the profile's Git and proxy configuration and a default `githubConnectionTimeoutMs` of 5000 ms. Credential helpers and prompts are disabled for this check, so authentication cannot consume the connection budget. Only network failures and timeouts prevent pnpm from starting; pnpm still owns authentication, HTTPS-to-SSH fallback, ref resolution and the full installation. The budget does not limit downloads or builds. The existing failure kind and `failedAt: 'spec-host'` let the Client show a connection error or timeout and offer a domestic registry for a replacement package spec. Cancellation and manager disposal terminate the check and its descendants before settling.
+
 **Cancellation is the manager's, not the signal's.** The dialog generates a request id for each run; the Host streams the run's output and phases under it, and `cancelInstall` answers only after pnpm exited and the files are back. The dialog waits for that answer before offering the spec again; an aborted RPC or a lost connection is not a confirmation. Only the check takes a trailing `AbortSignal`: going back or closing drops a registry lookup, whose settlement nothing waits for.
 
 **Enabling comes after the fact.** The run installs with `enabled: false`; the finished screen offers **Enable now** for the bundle it added, and the dialog closes and the list scrolls to it. Nothing is enabled before the person has seen what was installed.

The dialog is four screens over one subject card.
 
 ## Testing
 
 `packages/boot/plugin-manager/tests/install-spec.spec.ts` pins the spec forms and the failure classifier's inputs; `manager.spec.ts` drives `inspect` against a stubbed registry lookup and a real directory, streams a run, stops one and checks the restored files, and checks the change events; `operations.spec.ts` covers the registry lookup. `packages/client/ui-plugin-manager/tests` cover the store's phases, Host-confirmed cancellation, post-install enabling, toasts, and the page's four screens; `apps/web/tests/plugin-manager.e2e.ts` refuses an installed name, a missing path, and a bad name through the real Host and switches a bundle and one of its rows live, and `plugin-install-cancel.e2e.ts` stops a real child from the dialog, checks the restored files, and installs on the second try, and `plugin-install-approve.e2e.ts` leaves a script undecided through the fake pnpm, allows it from the dialog, and installs on the retry.
+
+`github-connection.spec.ts` uses real Git against owned loopback transports to cover immediate failure, timeout, cancellation and noninteractive authentication. `manager.spec.ts` also installs a local repository through real Git and pnpm for HTTPS, GitHub shorthand and SSH specs, isolating pnpm's HTTPS probe through an owned proxy and verifying its SSH fallback. `plugin-install-github.e2e.ts` checks the connection error and timeout dialogs, child cleanup, and switching to a mirror without retrying the old GitHub address.

 Worktree isolation is not a harness runtime behavior. A deployment or prompt may arrange separate worktrees, but the Team domain does not infer branches, merge changes, or silently change cwd. This preserves the existing same-world subagent and sandbox contracts.
 
+## Web projection
+
+The Web panel reads the Lead Session's `agentTeam` wire projection because the existing projection stream keeps browser state current without a separate Team read API. Both Lead and teammate conversations select values from the shared cross-Session store. The panel owns no projection reads: Session loading, cached list values, and control baselines supply the data.
+
+The wire view carries durable roster phases, non-deleted task views with shared readiness and overlap derivation, and `failure` beside the last valid state. Live activity comes from Session status. Model selection has its own durable projection; the panel displays the shared store's available values without opening member conversations. A missing cached value remains absent until Session loading or a live update supplies it.
+
+Publication requires `apply` to return a new state object per applied Team event and replace only the touched collection. Mailbox-only events retain the view reference and publish nothing. The existing carrier sends each changed complete view to every connected browser; the package README records that cost.
+
 ## Alternatives considered
 
 **Extend direct-child subagent tools with peer ids.** Rejected because parent/child authority and Team peer membership are different domains. Adding peer access to the continuation seam would weaken its exact-parent authorization and still leave roster and tasks without a persistence owner.

+
+传输视图携带持久 roster phase、使用共享就绪与重叠派生逻辑的未删除任务视图，以及最后有效状态旁的 `failure`。实时活动来自 Session 状态。模型选择有自己的持久投影；面板展示共享 store 中可用的值，不打开成员会话。缺少的缓存值保持缺失，直到 Session 加载或实时更新提供它。

 `inspect(spec, options)` reads what a spec names before anything installs: a registry name is asked of the registry through `pnpm view`, run in the profile directory so the same proxy and authentication settings apply as to the install; an absolute path has its `package.json` read; a git address or tarball answers only its form and the `host` it is fetched from. The answer carries the name, version, description, whether the package declares a bundle, and the `registry` that answered, or a `problem`: `invalid-spec`, `already-installed`, `not-found`, `not-a-package`, `not-a-bundle`, `network`, or `unknown`, with the `registries` asked. A caller's `signal` or `inspectTimeoutMs` ends the lookup.
 
+`installBundle` checks GitHub repositories with `git ls-remote` before starting pnpm, using the profile directory and the installer's Git and proxy configuration. `githubConnectionTimeoutMs` defaults to 5000 ms and limits only this check, not package download or builds. The check disables credential helpers and prompts; only network failures and timeouts stop installation, reporting `failedAt: 'spec-host'` with the existing failure kind and diagnostic log. Authentication, repository lookup and other failures are left to pnpm, including its HTTPS-to-SSH fallback. Cancellation and manager disposal stop the check and its descendants. Registry packages, paths, tarballs and other Git hosts skip this check. A reachable repository can still fail during download or bundle validation.
+
 Registries are asked in turn. The plan starts at `options.registry`, else the configured `registry` (`null` is the one pnpm's own configuration names), and continues through `fallbackRegistries` while a registry is unreachable, times out, or answers that it has no such package or version, which a mirror not yet synced does. A registry outside the configured set is asked alone, so a private registry never falls through to a public one; pnpm's own registry counts as part of the set only while what it names, read through `pnpm config get registry` before each plan, is npm's own registry or one of the fallbacks, and is otherwise asked alone as a private one. A registry pnpm's own configuration already names is asked once. The lookup runs `pnpm view` with `--registry` and without pnpm's own retries, so a dead registry is reported within `inspectTimeoutMs` and the next one is asked; pnpm prints its refusal as JSON on stdout, which is read like stderr. The install keeps pnpm's retry settings. `registries()` answers the configured set and what pnpm names, for a picker. The [registry Agent Note](../../../.agents/notes/implemented/architecture/2026-09-18-plugin-install-registries.md) owns the rationale.
 
 The browser-safe `@deepseek-ai/dsh-plugin-manager/registry` entry exports `OFFICIAL_NPM_REGISTRY` and `NPMMIRROR_REGISTRY` for consumers that identify those public registries.
 
-`installBundle` accepts a caller-generated `requestId`, under which `plugin-manager/install-log` streams each pnpm run's output and `plugin-manager/install-state` announces `installing`, `cancelling`, and `applying`; `installing` is announced once per registry asked, with the `attempt`'s registry, position, and the plan's length. The install asks the same plan as the lookup, from `options.registry`, running `pnpm add` with `--registry` and restoring the profile files between attempts; it moves on for the failures another registry can change and stops at any other, and at a failure whose error line names the host a git or tarball spec is fetched from, which no registry stands in for; `failedAt` says which of the two the last failed run could not reach. `cancelInstall(requestId)` stops the run and answers `cancelled` only after pnpm exited and the files are back, `too-late` once the bundle is being applied, and `not-running` for any other id; the install call then reports `application: 'cancelled'`. A run that fails, is cancelled, or adds a package without a bundle patch restores `package.json` and `pnpm-lock.yaml` as they were; `packageResult.kind` classifies the last run from its exit and output, `registries` names every registry asked, and `bundle` names the package a finished run added. `listBundles` carries each bundle's one-liner (the package `description`), the rows its patch declares with their live entries, and the built-in rows it overrides; it lists the profile's own bundles, the bundles the installation supplies, and a selected name without a bundle patch as a `not-bundle` problem, while an unselected plain dependency is left out. A bundle the launcher's `OPTIONAL_BUNDLES` names is `optional`: shipped switched off for the person to turn on, never removable, and selected by no shipped template ([rationale](../../../.agents/notes/implemented/process/2026-09-15-shipped-optional-bundles.md)). Every completed operation emits `plugin-manager/changed`; a patch generation applied outside the manager, by HMR's watcher after a CLI or hand edit, announces nothing, so the page learns of it on its next read.

The install asks the same plan as the lookup, from `options.registry`, running `pnpm add` with `--registry` and restoring the profile files between attempts; it moves on for the failures another registry can change and stops at any other, and at a failure whose error line names the host a git or tarball spec is fetched from, which no registry stands in for; `failedAt` says which of the two the last failed run could not reach. `cancelInstall(requestId)` stops the run and answers `cancelled` only after the Git check or pnpm exited and the files are back, `too-late` once the bundle is being applied, and `not-running` for any other id; the install call then reports `application: 'cancelled'`. A run that fails, is cancelled, or adds a package without a bundle patch restores `package.json` and `pnpm-lock.yaml` as they were; `packageResult.kind` classifies the last run from its exit and output, `registries` names every registry asked, and `bundle` names the package a finished run added. `listBundles` carries each bundle's one-liner (the package `description`), the rows its patch declares with their live entries, and the built-in rows it overrides; it lists the profile's own bundles, the bundles the installation supplies, and a selected name without a bundle patch as a `not-bundle` problem, while an unselected plain dependency is left out. A bundle the launcher's `OPTIONAL_BUNDLES` names is `optional`: shipped switched off for the person to turn on, never removable, and selected by no shipped template ([rationale](../../../.agents/notes/implemented/process/2026-09-15-shipped-optional-bundles.md)). Every completed operation emits `plugin-manager/changed`; a patch generation applied outside the manager, by HMR's watcher after a CLI or hand edit, announces nothing, so the page learns of it on its next read.
 
 `waitForInstall(requestId)` lets a client recover a lost response by waiting for the active installation, including its non-cancellable application phase. It returns the same outcome as the original call, or `null` if the request is not active. Completed results are not retained; `null` establishes neither success nor cancellation.

 `inspect(spec, options)` 在任何东西安装之前读出 spec 指向什么：注册表包名通过 `pnpm view` 询问注册表，在 profile 目录中运行，因而与安装使用同样的代理与认证设置；绝对路径读取其 `package.json`；git 地址或 tarball 只答复自己的形式和它被拉取的 `host`。答复携带名称、版本、描述、该包是否声明组合包，以及作答的 `registry`，否则给出 `problem`：`invalid-spec`、`already-installed`、`not-found`、`not-a-package`、`not-a-bundle`、`network` 或 `unknown`，并附上问过的 `registries`。调用方的 `signal` 或 `inspectTimeoutMs` 会结束查询。
 
+`installBundle` 在启动 pnpm 前通过 `git ls-remote` 检查 GitHub 仓库，使用 profile 目录及安装器的 Git 与代理配置。`githubConnectionTimeoutMs` 默认为 5000 毫秒，只限制这次检查，不限制包下载或构建。检查禁用凭据助手和认证提示；只有网络失败与超时会停止安装，通过现有失败类型与诊断日志返回，并标记 `failedAt: 'spec-host'`。认证、仓库查找及其他失败继续交给 pnpm，包括其 HTTPS 到 SSH 的回退。取消安装或销毁管理器会停止检查及其子进程。注册表包、本地路径、压缩包和其他 Git 主机跳过此检查。仓库可达后，下载或组合包验证仍可能失败。
+
 注册表按顺序询问。计划从 `options.registry` 开始，否则从配置的 `registry`（`null` 即 pnpm 自身配置指定的那个）开始，并在一个注册表不可达、超时或答复没有这个包或版本（尚未同步的镜像会如此）时继续问 `fallbackRegistries`。配置集合之外的注册表只问它自己，因而私有源永远不会落到公共源；pnpm 自身的注册表只在它指向的地址（每次做计划前经 `pnpm config get registry` 读出）是 npm 官方源或某个备选源时才算集合成员，否则视为私有源只问它自己。pnpm 自身配置已经指向的注册表只问一次。查询以 `--registry` 运行 `pnpm view` 且不带 pnpm 自身的重试，所以死掉的注册表会在 `inspectTimeoutMs` 内报告并转问下一个；pnpm 把拒绝以 JSON 打印在 stdout，读法与 stderr 相同。安装保留 pnpm 的重试设置。`registries()` 把配置集合和 pnpm 指向的地址答复给选择器。[注册表 Agent Note](../../../.agents/notes/implemented/architecture/2026-09-18-plugin-install-registries.zh.md) 拥有理由。

 Installed bundles and their plugin rows display their own title and description in the current UI language on cards and detail pages. Each field falls back from exported locale `meta` to the accessible `package.json` at that plugin address; the final title is the full package or module name, with no package description when both sources omit it. See [Plugin display metadata](../../../docs/cookbook/adding-a-package.md#plugin-display-metadata) for the author format.

 During preparation and download, **Cancel install** asks the Host to stop the run and waits for confirmation. Loading the bundle cannot be cancelled. Closing with ×, Escape, or the backdrop hides the dialog immediately and requests cancellation when possible. **View installation** reopens the same task with its output; another installation cannot start while its outcome is pending or unconfirmed. Confirmed cancellation returns to the spec and shows a toast; the manifest and lockfile are restored, while downloaded files can remain. A lost installation response triggers a request to recover the result; **Check installation status** and reconnect retry that request. If the Host has no active request, **Installation result unavailable** allows returning to editing after checking the plugin list. A cancellation sent before acceptance waits and retries automatically; a failed cancellation can be retried manually. Hidden tasks report their outcome through toasts without reopening the dialog.

 Custom item pages use the Host entry id as their registration id; row pages use the bundle package and row id. The page owner supplies `form.state` and `form.mutate(operations, expectedRevision)` when the entry exposes editable Config fields. A custom page owns its draft and validation display, and may reuse `ConfigField` from ui-primitives. Bundle-wide pages can contain several entries and have no single form.
 
-The page's `main` registration declares `plugins.item`, `plugins.bundle.config`, and `plugins.row.config` as its children, so the slots exist while the page does and a registrant's `ctx.slots.inject` waits for them. `configLedgerSource` projects the three ledgers into one observable — the official items in ledger order with their labels resolved in the active locale, and the bundle and row keys — cached until a ledger or the locale moves; the page binds it as `useConfigLedger` beside the store and never names a configurable plugin itself. Which page is open is page-local state: the cards, a bundle, an official plugin, or a row of a bundle. A registration lives with the browser half that made it. `dsh-client-modules` attaches a package's browser half to the Loader row whose specifier is the bare package name, so every page a bundle registers, for itself or for any of its rows, goes away when that row is switched off; a sub-plugin whose page must outlive the other rows ships as its own package. Official packages whose names begin with `@deepseek-ai/dsh-experimental-` display the Beta marker.
+The page's `main` registration declares `plugins.item`, `plugins.bundle.config`, and `plugins.row.config` as its children, so the slots exist while the page does and a registrant's `ctx.slots.inject` waits for them. `configLedgerSource` projects the three ledgers into one observable — the official items in ledger order with their labels resolved in the active locale, and the bundle and row keys — cached until a ledger or the locale moves; the page binds it as `useConfigLedger` beside the store and never names a configurable plugin itself. Which page is open is page-local state: the cards, a bundle, an official plugin, or a row of a bundle. A registration lives with the browser half that made it. `dsh-client-modules` attaches a package's browser half to the Loader row whose specifier is the bare package name, so every page a bundle registers, for itself or for any of its rows, goes away when that row is switched off; a sub-plugin whose page must outlive the other rows ships as its own package. Official packages whose names begin with `@deepseek-ai/dsh-experimental-` display the Experimental marker.
 
 `plugins.bundle.config` supplies bundle detail configuration, keyed by npm package name. `plugins.bundle.activation` offers bundle-owned guidance after explicit enablement from the list, with callbacks to dismiss it or open the bundle details. It does not appear merely because an enabled bundle was listed.

 ## Use this package
 
-The session header keeps the current session title as the lineage breadcrumb; when the session's direct catalog has entries or a read has failed, the descendant-count trigger renders in the header actions band after the task list, with no breadcrumb separator. An absent catalog, an empty loading catalog, or a successfully loaded empty catalog hides the count trigger. The trigger opens that direct catalog, reports its total and running counts, and loads nested catalogs only when their rows expand. Select any depth to open that child's conversation with its exact `{parentSessionId, childSessionId, mode}` address, or use the row's trailing arrow to open the same address in the right Sidebar, preferring a separate pane when room permits.
+The session header keeps the current session title as the lineage breadcrumb; when the session's direct catalog has entries or a read has failed, the descendant-count trigger renders at the start of the header actions band, with no breadcrumb separator. An absent catalog, an empty loading catalog, or a successfully loaded empty catalog hides the count trigger. The trigger opens that direct catalog, reports its total and running counts, and loads nested catalogs only when their rows expand. Select any depth to open that child's conversation with its exact `{parentSessionId, childSessionId, mode}` address, or use the row's trailing arrow to open the same address in the right Sidebar, preferring a separate pane when room permits.
 
 This package registers the `dsh-resource://subagentchat/session/<child>?parent=<parent>&mode=<mode>` resource and builtin Sidebar tab type. The resource retains the child `SessionReference` directly from its address without refreshing the parent catalog, and releases the reference when the tab record closes. The tab renders the shared `conversation.content` Factory through `sidebar.chat.conversation`, fixes the local View to Chat, and omits the main Conversation header and width controls.
 
 ### Browsing the tree
 
+Hovering a trigger opens its catalog after 150ms; leaving both trigger and catalog closes it after 120ms. Clicking the descendant-count trigger pins its catalog until outside click or Escape from the trigger or tree. Breadcrumb-title clicks navigate to the corresponding conversation.
+
 Rows display mode plus activity and an optional log-backed title; running uses the shared ongoing loader, an inactive child whose latest closed turn completed normally uses the shared success dot, and other inactive children use the shared idle dot. Every row reserves the same 14px status column, centering smaller dots so titles align with the loader state. The compact header trigger vertically centers its activity glyph and count with a 4px gap. The trailing column stacks total durable provider usage above active-turn duration. Keyboard navigation works with ArrowRight/ArrowLeft to expand and collapse branches and ArrowUp/ArrowDown, Home, End, and Escape to navigate or close the tree. An unlabeled one-shot row falls back to its session id. A row is a known leaf only after its own catalog loads empty.

 ## 使用本包
 
-会话页头把当前会话标题作为谱系面包屑；当会话的直接目录有子项或读取失败时，后代数量触发器渲染在页头操作区、任务列表之后，不带任何面包屑分隔符。目录缺席、空目录加载中或成功加载为空时，均隐藏数量触发器。触发器打开该直接目录，报告总数与运行数，并且只在行展开时加载嵌套目录。选择任意深度，即可用该子会话的确切 `{parentSessionId, childSessionId, mode}` 地址打开其对话；也可以使用行尾箭头在右侧 Sidebar 打开同一地址，并在空间允许时优先使用独立分栏。
+会话页头把当前会话标题作为谱系面包屑；当会话的直接目录有子项或读取失败时，后代数量触发器渲染在页头操作区的最前方，不带任何面包屑分隔符。目录缺席、空目录加载中或成功加载为空时，均隐藏数量触发器。触发器打开该直接目录，报告总数与运行数，并且只在行展开时加载嵌套目录。选择任意深度，即可用该子会话的确切 `{parentSessionId, childSessionId, mode}` 地址打开其对话；也可以使用行尾箭头在右侧 Sidebar 打开同一地址，并在空间允许时优先使用独立分栏。
 
 本包注册 `dsh-resource://subagentchat/session/<child>?parent=<parent>&mode=<mode>` 资源与 builtin Sidebar tab 类型。资源直接根据地址保留 child 的 `SessionReference`，不刷新 parent 目录，并在 tab 记录关闭时释放 reference。tab 通过 `sidebar.chat.conversation` 渲染共享 `conversation.content` Factory，把局部 View 固定为 Chat，并省略主 Conversation 的 Header 与宽度控制。
 
 ### 浏览目录
 
+悬停触发器 150ms 后打开目录；指针离开触发器和目录后，经过 120ms 关闭。点击后代数量触发器会固定目录，直到点击外部，或在触发器或树内按 Escape 关闭。点击面包屑标题会导航至对应会话。
+
 行显示 mode、活动状态与由日志支撑的可选 title；running 使用共享 ongoing loading，最近一个已结束轮次正常完成的 inactive child 使用共享 success 绿点，其他 inactive child 使用共享 idle 灰点。每行都为状态图标预留相同的 14px 列宽，并将较小的圆点居中，使 title 与 loading 状态对齐。紧凑的页头触发器会垂直居中活动图标与数量，并保留 4px 水平间距。尾随列在上行显示提供方的持久化 token 用量总计，在下行显示活跃轮次耗时。键盘导航：ArrowRight/ArrowLeft 展开和折叠分支；ArrowUp/ArrowDown、Home、End 与 Escape 用于导航或关闭树。没有 label 的 one-shot 行回退到其会话 id。只有一行自身的目录加载为空后，它才是已知叶子。

 - **One process and one shared checkout** — members share cwd and observe edits immediately; this package provides no worktree, remote member, merge, or filesystem lock.
 - **Advisory write scopes** — Bash, formatters, code generators, and direct external writers can bypass filesystem version checks; Leads must coordinate ownership and review the final diff.

 ## Summary
 
-This package adds an Agent Teams action to the Web conversation header, where a user can inspect the current roster, inspect the shared task board, and navigate into a teammate's conversation. It reads authoritative Team state through the generated `ctx.remote.agentTeams` contribution and keeps ordinary child-history navigation on the stable addressed-subagent path. Choose it through the published experimental Agent Teams bundle. The browser projection does not extend the stable API Proxy, store Team state, or register model-facing input.
+This package adds an Agent Teams action to the Web conversation header, where a user can inspect the current roster, inspect the shared task board, and navigate into a teammate's conversation. It reads the Lead Session's `agentTeam` projection from the shared Session store, where Host projection frames keep it current without a refresh control, and keeps ordinary child-history navigation on the stable addressed-subagent path. Choose it through the published experimental Agent Teams bundle. The browser projection does not extend the stable API Proxy, store Team state, or register model-facing input.

 ### Inspect and navigate the roster
 
-Opening the panel calls `agentTeams/view`. Roster rows show durable names, turn availability, model, and diagnostics. Provisioning and running members use the shared ongoing loader, inactive members use idle, and failed members use error. Selecting a healthy teammate opens the ordinary `{ parentSessionId, childSessionId, mode: 'continuable' }` address from its Lead and roster identity without refreshing or checking the parent catalog. The Host validates the parent, child, and mode when history opens. History and later human prompts continue through the stable addressed-subagent conversation path; this package adds no Team-specific address field.
+The panel shows the Lead Session's roster and task board from the shared Session store. Task and roster updates appear while the panel stays open. Opening the panel performs no projection requests. The panel shows a loading notice while the conversation or Session list is loading, and an unavailable notice when no Team value is present afterward.
+
+Roster rows show durable names and phases. Provisioning and running members use the shared ongoing loader, inactive members use a person icon, and failed members use error. Live Session status supplies running activity; the shared `modelSelection` projection supplies a model when available. The current conversation carries a Current chat tag and cannot be selected. Selecting the Lead from a teammate conversation opens the Lead Session directly. Selecting an active teammate opens its ordinary continuable child address. The Host validates the parent, child, and mode when history opens; later human prompts use the same addressed-subagent conversation.
 
 ### Inspect the task board
 
 Ready pending tasks use idle, blocked pending tasks use warning, in-progress tasks use ongoing, and completed tasks use done.
 
-The read-only task board shows task identity, owner, blockers, readiness, advisory write scopes, and overlap warnings. Team agents create and update tasks through their tools; the panel provides no task mutation controls.
+The read-only task board shows task identity, owner, blockers, readiness, advisory write scopes, and overlap warnings. Descriptions longer than two lines have an expand toggle. Section headings show member and task counts; an empty board shows a short description, and a lone member with no tasks uses a single-column panel. Team agents create and update tasks through their tools; the panel provides no task mutation controls. When the projection reports a rejected persisted Team record, the panel shows that failure above the last valid roster and tasks.

+The Client export registers its locale dictionaries and one conversation-header slot through Cordis effects; it mounts no Remote namespace. Disposing the plugin fiber removes both registrations.
 
-The panel renders outside the conversation container and stays within the viewport. Opening moves focus into the panel; Escape or Close returns focus to its trigger. Clicking outside or moving focus outside the panel and trigger closes it without moving focus back. Opening or refreshing the panel reads the complete Team view. Overlapping refreshes keep the newest response, and responses for a previous conversation are ignored.
+The panel renders outside the conversation container and stays within the viewport. Member cards use the shared elevation stroke for their outlines in resting, selected, and hover states. Hovering the trigger opens the panel after 150ms; leaving both trigger and panel closes it after a 120ms grace period. Clicking the trigger pins the panel and moves focus into it. Outside clicks and Escape dismiss the panel; Escape returns focus to the trigger only when focus was inside the panel. In a narrow header, the trigger becomes an icon and opens only on click. The component derives every row from the `useSessions`, `useSessionStatus`, and `useSession` seats: the Lead identity comes from the current Session's subagent address, the Team view from `projectionsBySession[lead].values.agentTeam`, member activity from Session status with the list summary as fallback, and the model from `projectionsBySession[member].values.modelSelection.next`. Each roster row selects its own running state. The only injected callback opens a roster Session using the current and target Session ids. Switching conversations closes the panel and clears a navigation failure.

 ### 检查并导航 roster
 
-打开 panel 会调用 `agentTeams/view`。Roster row 展示持久 name、轮次可用状态、model 与 diagnostics。provisioning 和 running 成员使用共享 ongoing loading，inactive 成员使用 idle 灰点，failed 成员使用 error 红点。选择健康 teammate 时，系统直接根据其 Lead 与 roster 身份打开普通的 `{ parentSessionId, childSessionId, mode: 'continuable' }` address，不刷新或检查 parent catalog。Host 在打开历史时校验 parent、child 与 mode。History 与后续人类提示词继续使用稳定 addressed-subagent 会话路径；本包不会添加 Team 专用 address 字段。

+Roster 行展示持久名称与阶段。provisioning 和 running 成员使用共享 ongoing loading，inactive 成员使用人物图标，failed 成员使用 error 红点。实时 Session 状态提供运行活动；共享 `modelSelection` 投影在可用时提供模型。当前会话带有“当前会话”标签且不可选择。在 teammate 会话中选择 Lead 会直接打开 Lead Session。选择 active teammate 会打开其普通 continuable 子会话地址。Host 在打开历史时校验 parent、child 与 mode；后续人类提示词使用同一 addressed-subagent 会话。
 
 ### 查看任务板

+Client export 通过 Cordis effect 注册 locale dictionary 与一个 conversation-header slot；它不挂载任何 Remote namespace。Dispose plugin fiber 会移除这两项 registration。
 
-面板渲染在会话容器外，并保持在视口范围内。打开时焦点移入面板；按 Escape 或选择关闭按钮时，焦点返回触发按钮。点击外部或将焦点移出面板与触发按钮时，面板关闭，但不会将焦点移回。打开或刷新面板会读取完整 Team view。并行刷新只保留最新响应，属于上一个会话的响应会被忽略。
+面板渲染在会话容器外，并保持在视口范围内。成员卡片在静止、选中和悬停状态下均使用共享 elevation 描边绘制轮廓。悬停触发按钮 150ms 后打开面板；指针离开触发按钮和面板后，经过 120ms 宽限关闭。点击触发按钮会固定面板并将焦点移入其中。点击外部或按 Escape 可关闭面板；仅当焦点原本位于面板内时，Escape 才将焦点返回触发按钮。页头较窄时触发按钮折叠为图标，只响应点击打开。组件从 `useSessions`、`useSessionStatus` 与 `useSession` 座位派生每一行：Lead 身份来自当前 Session 的 subagent address，Team 视图来自 `projectionsBySession[lead].values.agentTeam`，成员活动来自 Session 状态并以列表摘要为后备，model 来自 `projectionsBySession[member].values.modelSelection.next`。每个 roster 行只选择自己的运行状态。唯一的注入回调通过当前与目标 Session 的 id 打开 roster Session。切换会话会关闭面板并清除导航失败。
