+# Agent Note: Web UI abbreviates POSIX home paths as `~`
+
+Status: implemented
+
+English | [中文](2026-08-18-web-home-path-tilde.zh.md)
+
+## Problem
+
+Workspace hover cards and Tool call summaries showed full POSIX home paths. Those strings are long, repeat the same prefix on every row, and make the sidebar and transcript harder to scan. Windows paths must stay verbatim because `~` is not a Windows filesystem convention.
+
+## Decision
+
+`host.describe` reports the host account `home` as a required field. Client and Host ship together, so the field is required rather than optional. ApiProxy fills it from `homedir()` at describe time.
+
+`abbreviateHomePath` in `dsh-client-runtime` is the display-only helper. It returns `~` or `~/…` when the path is the POSIX home or a descendant, and leaves the path unchanged when `home` is missing, empty, or `/`, when either value is a Windows drive or UNC path, or when the match is only a prefix (`/Users/u` does not claim `/Users/u2`). Tool summaries run workspace-relative shortening first, then this helper, so a path inside the session cwd stays short. `filePath`, Host open, and Workspace hover copy keep the authored filesystem path.
+
+`ui-tool` and `ui-workspace` inject `connection.hostDescription` at their own slot registrations. ChatView does not grow a Host-description hook. A missing `hostDescription` on an incomplete test fake falls back to an absent source, so abbreviation does not run.
+
+The fixture Host home is `/home/fixture`. A second fixture Workspace at `/home/fixture/Documents/project` lets assembled replay hover `~/Documents/project` without moving the existing `/tmp/fixture` account. TerminalBlock's own prompt-label collapse is unchanged.
+
+## Alternatives considered
+
+**Guess `/Users` or `/home` without the real home.** Rejected because a shared prefix is not an account home, and `/Users/shared` or `/home/src` would abbreviate incorrectly.
+
+**Abbreviate Windows `%USERPROFILE%` as `~` as well.** Rejected because the acceptance rule keeps Windows paths verbatim, and `~` is not how Explorer or `cmd` spell those paths.
+
+**Put the helper in `dsh-home-paths`.** Rejected because that package expands configuration tildes on Node; this helper is a browser display rewrite and must not pull Node `os` into client bundles.
+
+**Thread `home` from ChatView owner props.** Rejected because it enlarges the conversation inject face and every ChatView test harness for a display fact only Tool and Workspace cards consume.
+
+## Consequences
+
+POSIX home-rooted Workspace hover paths and leftover Tool path summaries display as `~`. Copy and open still use the full path. Windows drive and UNC paths never become `~`. A Host that reports `/` as home does not turn the whole filesystem into `~`. Incomplete test connection fakes without `hostDescription` render unabbreviated paths instead of hanging or throwing.
+
+## Testing
+
+Package tests cover `abbreviateHomePath`, `toolRowModel` / `readCardModel` home abbreviation, Workspace hover display versus copy, and `host.describe` schema plus live `homedir()`. Assembled replay `apps/web/tests/home-path-tilde.snapshot.ts` hovers the fixture home-descendant Workspace. Product-GUI PRs still record a real-browser GIF of the hover card.

+
+## Problem
+
+Workspace 悬停卡片和 Tool 调用摘要会显示完整的 POSIX 家目录路径。这些字符串很长，每行重复同一前缀，侧边栏和对话记录更难扫读。Windows 路径必须保持原样，因为 `~` 不是 Windows 文件系统约定。
+
+## Decision
+
+`host.describe` 把宿主账户的 `home` 作为必填字段上报。Client 与 Host 一同发布，因此该字段是必填而不是可选。ApiProxy 在 describe 时用 `homedir()` 填入。
+
+`dsh-client-runtime` 中的 `abbreviateHomePath` 是仅用于展示的辅助函数。当路径是 POSIX 家目录或其后代时返回 `~` 或 `~/…`；`home` 缺失、为空或为 `/`，任一侧是 Windows 盘符或 UNC 路径，或只是前缀命中（`/Users/u` 不能收走 `/Users/u2`）时，路径保持不变。Tool 摘要先做工作区相对缩短，再调用该辅助函数，因此会话 cwd 内的路径仍然更短。`filePath`、Host 打开以及 Workspace 悬停复制仍使用作者给出的文件系统路径。
+
+`ui-tool` 与 `ui-workspace` 在各自的 slot 注册上注入 `connection.hostDescription`。ChatView 不增加 Host 描述钩子。测试假对象若缺少 `hostDescription`，会回退到空来源，因此不会进行缩写。
+
+fixture 的 Host 家目录是 `/home/fixture`。第二个 fixture Workspace 位于 `/home/fixture/Documents/project`，组装回放可以悬停出 `~/Documents/project`，而不必移动现有的 `/tmp/fixture` 账户。TerminalBlock 自有的提示符标签折叠保持不变。
+
+## Alternatives considered
+
+**在没有真实 home 的情况下猜测 `/Users` 或 `/home`。** 否决，因为共享前缀不是账户家目录，`/Users/shared` 或 `/home/src` 会被错误缩写。
+
+**同样把 Windows `%USERPROFILE%` 缩写成 `~`。** 否决，因为验收规则要求 Windows 路径保持原样，而且 Explorer 与 `cmd` 并不这样拼写这些路径。
+
+**把辅助函数放进 `dsh-home-paths`。** 否决，因为该包在 Node 上展开配置里的波浪号；本辅助函数是浏览器展示改写，不能把 Node `os` 拉进 client 包。
+
+**从 ChatView owner props 向下传递 `home`。** 否决，因为它会扩大 conversation 注入面和每一份 ChatView 测试夹具，而只有 Tool 与 Workspace 卡片消费这个展示事实。
+
+## Consequences
+
+POSIX 家目录下的 Workspace 悬停路径，以及缩短 cwd 后仍落在家目录里的 Tool 路径摘要，会显示为 `~`。复制与打开仍使用完整路径。Windows 盘符和 UNC 路径永远不会变成 `~`。若 Host 把 `/` 报成 home，不会把整个文件系统收成 `~`。缺少 `hostDescription` 的不完整测试连接假对象会渲染未缩写路径，而不是挂起或抛错。
+
+## Testing
+
+包测试覆盖 `abbreviateHomePath`、`toolRowModel`／`readCardModel` 的家目录缩写、Workspace 悬停展示与复制，以及 `host.describe` schema 与实时 `homedir()`。组装回放 `apps/web/tests/home-path-tilde.snapshot.ts` 悬停 fixture 中位于家目录下的 Workspace。面向产品 GUI 的 PR 仍需录制悬停卡片的真实浏览器 GIF。

An emptied set is stored as an absent key, so absence and `[]` are one representation and consumers never test a sentinel. Two clears keep it from outliving its truth: `session/subscribed` drops the session's mirror, because a fresh generation sends a baseline only for a non-empty set and a retained list would survive as a phantom, and `host/session-removed` drops it again, because owner disposal removed the records on the mux stream while the removal frame rides the host stream, leaving the two with no relative order.

 Collapsed search is one header action beside the view and add actions. In the rail, add and search render as 36px controls on the shell's shared horizontal entry path. Activating search expands the field across the header; an outside click collapses only a query that is empty after trimming, while the clear control always resets and collapses it. A non-blank search query replaces either browsing mode with one flat result list: case-insensitive title and Workspace substring matches appear immediately, while a 250 ms debounced Host request adds ranked current-conversation content matches and snippets. The English search input and its defensive request path remove NUL, cap the query at the wire schema's 500 UTF-16 code units without splitting a surrogate pair, and preserve the existing debounce and cancellation behavior. Each new query aborts the preceding request; a failed content search leaves metadata matches visible with a warning. The list is capped at 20, asks the user to narrow broader queries, and opens the selected Session without clearing the query or jumping to a specific event.

Each registration declares a **directory-flow child hole** (`single` kind: `conversation.hero.workspace.directoryFlow` / `sidebar.workspaces.directoryFlow`) that the composed picker package's client half fills with its picking interaction — the [`-native`](../../host/directory-picker-native/README.md) backend's renderless OS-chooser driver today, an in-app browsing dialog under a `-browse` composition. The flat **Add workspace...** action renders only while the surface's hole is occupied (occupancy read per menu render; an empty hole means the composition has no picking affordance — the seam's documented no-flow default, under which the sidebar header drops its add button rather than offering a dead one). This package owns the trigger and the adoption: the occupant reports one picked path per open through the hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`), and the owner adopts it through the object layer, selecting the committed Workspace only after its list projection has refreshed; cancellation is silent, and errors land in the retryable folder dialog whose **Choose again** reopens the flow. Adding has exactly one route: the occupant's own create-folder affordance already covers a brand-new directory, so no separate create-by-name dialog exists. A menu only appears where there is something to choose between — with no Workspace listed, the anchor gesture raises the flow directly instead of a one-row popover, and it waits for the list baseline before treating an empty list as final. The runtime Session and Workspace services own materialization. The Workspace row's Delete action opens a confirmation that states the retention boundary, blocks duplicate submission, and keeps failures open; success removes the group while its Sessions remain under Ungrouped. The Session row's Rename action opens the same browser-owned dialog pattern prefilled with the row's display title: no client-side conflict rule exists (the host normalizes and may reject with `title-invalid`, rendered in the dialog alert), and confirming an unchanged title is deliberately allowed — it pins the current automatic title against regeneration. The Session row's Archive action commits without a confirmation dialog (non-destructive: the log and the workspace accounting slot remain) through `ctx.workspaces.archiveSession`; the row disappears from every grouping surface — workspace groups, Ungrouped, content search, and the flat list — when the archive-set echo lands, and failures are console diagnostics that leave the tree unchanged.

 Directory picking delegates to the composed `ctx.directoryPicker` backend ([the directory-picker seam](../directory-picker/README.md)); a method called outside the composed capability's kind fails with `directory-picker-unavailable` (the client needs no advertisement — the composed picker package's own client half renders the matching interaction). Under `native`, `host.pickDirectory` opens one native chooser and returns its selected path (`null` on cancel); this user-paced method does not use the default 30-second unary timeout, while caller/connection aborts still propagate to the native process. Under `browse`, `host.listDirectory` returns one name-sorted directory level with breadcrumb ancestry, a `home` anchor, and host-owned `hidden` flags (absent path = home directory), and `host.createDirectory` creates one validated child segment; the backend's typed failures map 1:1 onto the `directory-unreadable`/`directory-exists`/`directory-create-failed` codes. The browser carrier's prefix-wide trust fence (dsh-client-connection) covers all of these like every other `/api` request.
 
-`host.openPath` opens a filesystem path with the operating system's default application (`open` on macOS, `Invoke-Item` on Windows, and `xdg-open` on desktop Linux). For `.html`, `.htm`, `.xhtml`, and `.svg`, macOS and desktop Linux prefer a named default browser and fall back to that application handoff when none can be named. WSL translates every Linux path through `wslpath -w` and hands the resulting Windows/UNC path to Windows `Invoke-Item`, including browser-renderable documents, instead of assuming a Linux desktop association. `host.describe.canOpenPath` advertises whether that handoff can reach a user-visible desktop: explicit gateway `nativeOpen` wins, an injected opener is usable by definition, and platform detection otherwise accepts macOS, Windows, WSL, or Linux with a display while rejecting headless/container Linux. The browser carrier applies the same loopback, same-origin restriction as `host.pickDirectory`; clients combine both facts before presenting a native action.

The Web client uses it to display POSIX home-rooted paths as `~`; Windows values are still reported and are not abbreviated. `host.describe.canOpenPath` advertises whether that handoff can reach a user-visible desktop: explicit gateway `nativeOpen` wins, an injected opener is usable by definition, and platform detection otherwise accepts macOS, Windows, WSL, or Linux with a display while rejecting headless/container Linux.

 The `agentPreset.list` domain exposes the deployment's preset roster so a browser can offer a choice when starting a session; each row carries its `trust` (a `user` preset is exactly as privileged as the plugins it names), whether it is the current default, and — when the preset cannot compose a session — a `broken` reason, because a damaged directory still occupies its id and a surface must be able to show and delete it rather than offer it and fail the session start. A deployment composing no presets answers with an empty roster rather than an error, because sharing the host composition is a valid deployment. `agentPreset.select` recomposes one session's agent from a different preset, and is allowed only while the session is blank: once a turn has run, that history was produced under the preset's tools and swapping them would strand logged tool calls, so the attempt answers `agent-preset-locked`. The agent and the session survive — only the composition is swapped, and a failed swap restores the previous one.
