 - The host criterion: `session.events.length === 0` (zero log events = no user message yet). A live session reads `summarize()` straight from memory; a cold session is always `false` — the lazy-create contract guarantees a never-appended session never enters `persistence.list()` at all (both the JSONL and SQLite backends are verified truly lazy), so blank never touches disk.
 - The wire carries it in two places: the required `SessionSummary.blank` column, and the required `blank` field on the `host/session-added` frame (always true at creation, letting other tabs enter the same blank-session state into their mirrors).
 - The client mirror only lowers, never raises (monotonic), flipped from three sources, all reusing existing wire signals:
-  - The sender's own tab: the **successful response** to the first `prompt()` flips false (acceptance proves the user/message is already in the host log — this flip is confirmation, not optimism; `onEngaged` synchronously updates the list mirror, converting the current `New Session` row in place to an ordinary title, adding no list row). A rejected first prompt keeps the session blank: aligned with host authority, still shown as `New Session`, keeping its connectWorkspace reuse eligibility.

   - Other tabs: the `host/session-status (running:true)` frame flips it — a blank session never runs, so the first running necessarily means no longer blank;
   - Reconnect alignment: `session.list`'s summary.blank is authoritative, so a tab that missed frames aligns naturally on its next pull; a stale blank:true can never mark a converted session back to blank.
 - List discipline: the store retains every row; the Workspace browser's grouping, flat view, search, and counts share one visible projection — every non-blank session shows, while blank sessions show only the one with `session.id === sessions.current`, its title forced to `New Session`. After a Workspace switch, the old blank entity stays in the mirror but is hidden from the list while the target Workspace's current blank shows; the user-visible surface therefore holds at most one blank row globally.

 ### connectWorkspace: the sole entry point of New Session
 
 `workspaces.connectWorkspace(workspaceId): Promise<SessionId>` (owned by WorkspacesService — it holds both the workspace canonical path and the sessions reference):
 
-- The reuse arm: the list mirror is searched for `blank && cwd == workspace.path` (direct equality on the host realpath canonical form); a hit returns that id directly, creating nothing.
+- The reuse arm: the list mirror is searched for `blank && cwd == workspace.path && sessionIds.includes(id)` — the host's own membership rule, never cwd alone. A cwd match without the account slot (a CLI/TUI session birthed at the host cwd, or a deleted/recreated registration) would open a session no grouping surface can show under this Workspace, so it falls through to the create arm instead (see the [membership reuse fix](../bug-fix/2026-08-05-workspace-blank-session-reuse-membership.md)); a hit returns that id directly, creating nothing.
 - The create arm: on a miss, `session.create({workspaceId})` returns the new id.
 - An unknown workspaceId fails loud (never silently creating somewhere else).
 - The resolution guarantee (one contract for both arms): when the promise resolves, the returned id is already in the list store and `sessions.binding(id)` resolves synchronously — `SessionsService.create` projects the list synchronously after RPC success before resolving, so a draft mover can write text into the new scope's machine before open, without waiting for a notifier flush.

 ## Decision
 
-**Wire domains on the compiled RPC map, rejections as codes, invalidations as frames.** `settings.describe/update/replace`, `credentials.describe/set/unset`, `llm.providers`, and `llm.models` (claiming the reserved `host.listModels` surface) join `RpcMethodMap`, so the seven compiler-locked wiring sites keep contract, schema, handler, and client in lockstep. Seam rejections fold into `settings-rejected {ns}` / `credential-rejected {ref}` business errors (HTTP stays a carrier), and three `HostFrame`s — `host/settings-changed {ns}`, `host/credentials-changed {ref}`, `host/models-changed` — follow the `host/commands-changed` shape so every client converges without polling. Writes join `pickDirectory`/`openPath` in the connection guard's privileged set: loopback + same-origin or 403, because a LAN-exposed dsh web must not accept config mutation from another origin.

Settings reads, native actions, and writes join `pickDirectory`/`openPath` in the connection guard's privileged set: loopback + same-origin or 403, because a LAN-exposed dsh web must not accept configuration access from another origin.
 
 **`describe()` grows layers and structural secret redaction.** `SettingsDescriptor` carries `base`/`user` beside the effective value, so the form marks "overridden" by presence in the user layer, not value inequality (an override *equal* to the base is still an override). `describe({ redactSecrets: true })` — mandatory at every wire face — strips `role('secret')` subtrees from all three layers via a pure structural walk of the schema (object/dict/array containers; a secret-role subtree is one opaque leaf) and enumerates the stripped slots as `{path, set}`, so a page can render write-only inputs without ever receiving a value.
 
+**The Host identifies and opens the local settings document.** The settings seam exposes optional `documentPath` provider metadata and a `prepareDocument()` operation; `settings-local` returns its fully resolved custom or `$DSH_HOME/settings.yaml` filename and exclusively creates an absent empty document with owner-only permissions, while non-file providers retain the base `undefined`. The loopback-only `settings.describe` response carries only the boolean `hasDocument` capability beside the redacted namespace views. `ui-settings-general` registers a `settings.action` entry only on loopback pages, shows it only after the metadata confirms that a provider-owned local document can be prepared, and invokes pathless `settings.openDocument`; the Host resolves the provider path again before a text-document handoff (`open -t` on macOS so an arbitrary YAML file association cannot redirect the gesture, `xdg-open` on Linux, and `Invoke-Item` on Windows). Generic workspace paths retain the existing default-application handoff. The browser neither derives `$DSH_HOME` nor receives a filesystem target; remote pages make no privileged settings read for this action.
+
 **The llm seam declares configurability and announces topology.** `registerConfigurableProviders()` is an all-or-nothing, fiber-scoped directory of `{provider, displayName, settingsNs, settingsPath}` — the addressing a config page needs to open the right settings subtree for a route that may not exist yet; `listConfigurableProviders()` merges with live routes in the wire handler so undeclared live routes still report active. The zero-payload `'llm/adapters-updated'` event fires from all four registration/unregistration commit points with contained listener dispatch (INVARIANT rethrow), following the settings/commands precedent. `llm-deepseek`'s route renamed to `deepseek-official` because the pi-ai catalog legitimately owns `deepseek` as an aggregator entry; pre-release stance, no alias.
 
-**A hand-written editor over a schema model layer.** `dsh-client-schema-form` rehydrates the wire's `toJSON()` envelope into live schemastery nodes for validation, path resolution, and immutable draft editing — but no generic rendering: the first cut shipped a full schema-driven form renderer, and the resulting page was an unstyled schema dump (every advanced field flattened onto the card, raw field names as labels, the `retryPolicy` unsupported-fallback in the main flow). The user chose the hand-written direction over adding a hint/grouping system, and a second round removed the reference input entirely: the card's primary field is one **API key** input, a whole-section provider without a configured key opens as its setup card, and the collapsed 自定义设置 fold carries the curated per-family extras (`baseURL` for both families, plus `reasoningEffort` for deepseek / `reasoning` for pi-ai), with every other field owned by `settings.yaml`. Validation still runs the rehydrated schema before writing, so a hand-coded field that drifts from its schema fails loud on save rather than silently.

Existing model fields outside that visible set survive array edits; retry policy, timeouts, and other fields remain owned by `settings.yaml`. Validation still runs the rehydrated schema before writing, while adapter-specific checks reject catalog invariants that the serialized schema cannot express. The card's colors resolve through the `--dsw-alias-*` design tokens; it had named `--border`/`--surface`/`--text-*`, which nothing in this app defines, so it rendered their light-mode fallbacks and stayed light under the dark theme. The model catalog takes the row shape the pi-ai provider form introduces: one bordered entry per model, id and display name on the row, and the capacities behind the row's own disclosure, so the two editors read as one design rather than diverging once both land. Every field keeps the indexed `aria-label` that names it. Both capacities are text fields reading a decimal `K`/`M` suffix (`1M` is 1000K, matching how capacities are quoted) and storing the plain count: a field holds the typed text while it has focus, because re-deriving it from the parsed count on every keystroke would rewrite `1000` to `1K` mid-word, and text that does not parse stays on screen so the save-time rejection names a row the user can still see. The shared class names carry this file's token spellings, not that branch's: `--dsw-alias-border-subtle`, `--dsw-alias-text-tertiary`, and `--dsw-alias-text-primary` are undeclared, so they resolve to the light-mode literals in their fallback slots — the defect this section was moved off. A styles test now rejects any `--dsw-*` name the token sheet does not declare, so the next editor to name one fails rather than shipping a light-only surface.
 
-**The Models page is a three-domain join with seam-shaped apply semantics.** Rows are configured providers; the add card's select is the dormant directory remainder. Route liveness still gates readiness and invalidates the join, but the page does not render it as provider status because configuration presence and runtime availability are distinct. The key path stays reference-shaped without ever showing a reference: a typed key stores **write-only** through `credentials.set` under the profile's `apiKeyEnv`, deriving `<ROUTE>_API_KEY` when none exists (the pi-ai profile records the derivation), so `settings.yaml` never carries a key value. Profile edits and removals land as minimal path-addressed `settings.mutate` operations against the redacted user section, which never names a secret the page did not receive. Removing a user-layer provider first opens a localized model-provider confirmation dialog; cancellation, its close button, and its mask leave the profile untouched, while the destructive confirmation submits the single unset and blocks duplicate submission until it settles.

 - **Storing the typed key as a literal `apiKey` setting** — the v1 "one API key input" requirement could have written the literal into the profile, but every UI removal path rebuilds the user section from the *redacted* layers, so any reset or row deletion would silently drop stored sibling keys; deriving a reference keeps the input single-field while keeping `settings.yaml` secret-free and every replace safe.
 - **A `models` bridge plugin owning provider configuration** — same rejection as PR1: per-plugin namespaces plus a four-field directory declaration give the UI everything it needs; the bridge's unified dict re-imports the adapter-mapping indirection.
 - **Page-side polling instead of pushed frames** — the mux already carries `host/commands-changed`; three more frames cost one shape each and make a second tab, an external `settings.yaml` edit, and a settings-born route converge at event speed.
+- **Hard-coding `$DSH_HOME/settings.yaml` or returning `documentPath` through `host.openPath` in the browser** — rejected because `settings-local.path` may select another YAML/JSON document, non-file providers have no Host path, and a general path request makes the browser the authority for a local filesystem target. Provider preparation is the authoritative source, and the Host-owned operation feeds the existing opener.
 
 ## Consequences
 
-The whole loop is pinned keyless in the browser lane (`apps/web/tests/models-settings.e2e.ts`): the add card offers the dormant pi-ai catalog, adding `minimax-cn` with a typed key writes the reference-only profile into `settings.yaml`, stores the value into the harness home's `.env` under the derived `MINIMAX_CN_API_KEY`, registers the route live on the topology frame, and the customized fold merges `reasoning` beside the reference — zero model calls, ARIA goldens for the add-card, configured, and delete-confirmation states, plus a scaffold `harnessHome` so tests never touch a real `~/.dsh` (the provider under test is one whose derived reference cannot collide with a developer's exported keys). The removal scenario proves cancellation leaves the profile intact, confirmation removes it, and the intentionally retained credential survives. The rename touched 239 files (fixtures, goldens, docs, python) in one commit with no compatibility alias. The renderer replacement cost one commit and no wire change: apply semantics, redaction, and the directory join were renderer-agnostic all along. Deferred: a per-row models preview (the picker already lists models), a page address for live routes that never declared configurability, and explicit removal of a provider's retained credential.

+# Agent Note: The conversation column reserves one scrollbar gutter for every view
+
+Status: implemented
+
+English | [中文](2026-08-04-composer-tab-gutter-reservation.zh.md)
+
+## Problem
+
+The composer seat is one node in one place in the tree, and it was laid out against a different edge depending on which view tab was shown.
+
+In Chat it is a sticky CHILD of the column's scroller (`[data-conversation-scroll]`), so it rides that scroller's content box — the box a space-consuming scrollbar shortens by the bar's width. A view that declares `data-conversation-composer-overlay`, which Trajectory does, moves the column's scrolling into the view itself: the branch keyed on that attribute left the scroller `overflow: hidden` and positioned the seat absolutely, against the padding box, which no scrollbar reduces.
+
+So for as long as the transcript overflowed — the ordinary state of any session with history — the two tabs disagreed by exactly the bar's width. The input card is centred, so switching tabs moved it 4px sideways on an 8px bar, and its right-hand clearance changed by the full 8. The same displacement appeared inside Chat alone at the moment a growing transcript started to scroll, and again between the hero phase and the first scrolling turn.
+
+## Decision
+
+`.scrollBody` declares `scrollbar-gutter: stable` unconditionally, and the overlay branch declares the same box a scroll container on both axes — `overflow-x: hidden; overflow-y: auto` — instead of `overflow: hidden`.
+
+The two halves are one change. The reservation is what makes both states measure against the same width; declaring the overlay branch a scroll container is what makes the reservation reach it. `stable` rather than `auto` because `auto` reserves only while the box actually overflows, and the difference between overflowing and not is precisely the difference between the two tabs — an `auto` gutter would state the bug rather than fix it.
+
+The overlay state is a scroll container that nothing scrolls: the view fills it (`flex: 1 1 0` with its own clip) and the seat is out of flow, so no gesture and no clipping behavior changes. What changes is which declarations the engine honours. WebKit applies `scrollbar-gutter` to an `overflow-y: auto` box and ignores it on a hidden one — measured on this app's own composer layers and recorded in [the composer scrollport note](2026-07-31-composer-text-layers-share-one-scrollport.md) — so a reservation left on a hidden box would hold in Chromium and silently not in Safari.
+
+The horizontal axis is declared rather than left to compute: a box that scrolls on one axis computes `visible` on the other to `auto`, and would grow a horizontal scrollbar of its own the first time a view's content reached past the column.
+
+The reservation is worth what it costs only because the bar takes layout space here at all, which is not the browser's default behavior but this client's: `::-webkit-scrollbar` carries a width in ui-theme's sheet ([themed scrollbars](2026-07-28-themed-scrollbars-and-reserved-gutter.md)), and the sidebar's session list already reserves its own gutter for the same reason.
+
+## Alternatives considered
+
+**Inset the overlay seat by the bar's width.** The narrow reading of the bug — the two states differ by 8px, so subtract 8px from one. Rejected because the number is the engine's, not ours: the WebKit path draws the sheet's 8px bar, the Firefox path draws whatever `scrollbar-width: thin` resolves to, and a hardcoded inset would line the two states up in Chromium while drifting everywhere else. The gutter asks the engine to reserve its own bar's width, whatever that is.
+
+**Keep `overflow: hidden` and add `scrollbar-gutter: stable` alone.** The one-line version. It fixes the visible symptom on the engine the browser lane runs, and leaves it in place on Safari, with no test failing anywhere — the failure mode the second half of the change exists to prevent.
+
+**Move the composer seat out of the scroller in Chat too, making the overlay geometry the only geometry.** This deletes the difference at its root rather than reconciling it, and gives up a deliberate property: the sticky seat sits inside the scroll flow, so a wheel over the composer moves the transcript ([sticky composer](2026-07-29-sticky-composer-conversation-scroll.md)), and the fade mask above it is painted by the seat's own background. Both are owned behavior with their own coverage; rebuilding them to remove 8px of asymmetry is the larger change, not the smaller one.
+
+**Pad the column by the bar's width instead of reserving a gutter.** Padding applies whether or not a bar is present, so it costs the width unconditionally in every state, and it pins a value in the stylesheet that the engine picks at layout time. Rejected for the same reason the sidebar list rejected it.
+
+## Consequences
+
+- Chat's content column is permanently 8px narrower — in the hero phase and while the transcript is short as well, where no bar is drawn. That is the trade: one card position at every content height, instead of the widest possible column.
+- The fix covers three transitions with one declaration, because all three are the same difference: Chat ↔ Trajectory, short ↔ scrolling transcript within Chat, and hero ↔ first scrolling turn.
+- The overlay state is now a scroll container. Nothing in it can overflow today; a future view that let its content exceed the column would scroll this box instead of clipping, and would need its own clip the way the Trajectory view already has one.
+- The committed golden records the reserved band, so a change to the sheet's `::-webkit-scrollbar` width — the value that decides how wide the reservation is — arrives as a reviewable diff in this scenario as well as in the sidebar's.
+
+## Testing
+
+`apps/web/tests/composer-tab-geometry.e2e.ts` measures the input card's rectangle in both tabs, at a viewport where the card sits at its width cap and one where it shrinks with the column, and asserts the two rectangles are the same rectangle. Only a real engine reports this: jsdom gives every element a zero-sized box and no scrollbar, so a unit spec could assert the declarations exist but not that the two states land in the same place. For the same reason no CSS-text spec accompanies it — it would restate the declarations without adding a fact the browser lane does not already establish.
+
+The scenario launches chromium without Playwright's default `--hide-scrollbars`, which is load-bearing: under that argument a bar consumes no layout width, both tabs agree before this change as much as after it, and every comparison in the file holds vacuously. Measured, the pre-fix cascade leaves both bands at 0 under the argument, and at 8 and 0 with it dropped.
+
+The pre-fix cascade is then applied in the page — `scrollbar-gutter: auto` on the scroller, `overflow: hidden` on the overlay branch — and the same two tabs measured through it, which is what separates a card that does not move from a tab switch that never reached the layout. It reproduces the reported symptom as a number: 4px on each edge, half the 8px band. The golden records that control beside the fixed state, so the fixture carries the difference the change removes rather than only its absence.

+# Agent Note: 会话列为每个视图预留同一条滚动条槽
+
+Status: implemented
+
+[English](2026-08-04-composer-tab-gutter-reservation.md) | 中文
+
+## 问题
+
+composer 座位在组件树中只有一个节点、一个位置，但它究竟对齐到哪条边，取决于当前展示的是哪个视图标签页。
+
+在 Chat 中它是会话列滚动容器（`[data-conversation-scroll]`）的 sticky **子元素**，因而依附于该容器的 content box——而占布局宽度的滚动条会把这个盒子收窄一条滚动条的宽度。声明了 `data-conversation-composer-overlay` 的视图（Trajectory 即是其一）会把会话列的滚动搬进视图自身：以该属性为条件的那条分支把滚动容器留作 `overflow: hidden`，并把座位改为绝对定位——对齐的是 padding box，而滚动条从不收窄这个盒子。
+
+于是只要对话记录超出一屏——任何带历史的会话的常态——两个标签页就恰好相差一条滚动条的宽度。输入卡片是居中的，因此在 8px 的滚动条下切换标签页会让它横向移动 4px，而右侧留白整整变化 8px。同一位移也出现在 Chat 内部：对话增长到开始滚动的那一刻，以及从 hero 态进入第一个可滚动轮次时。
+
+## 决策
+
+`.scrollBody` 无条件声明 `scrollbar-gutter: stable`，overlay 分支则把同一个盒子在两个轴向上都声明为滚动容器——`overflow-x: hidden; overflow-y: auto`——而不再是 `overflow: hidden`。
+
+这两半是同一处改动。预留使两种状态依附于同一个宽度；把 overlay 分支声明为滚动容器，才使这条预留真正抵达它。选 `stable` 而非 `auto`，是因为 `auto` 只在盒子确实溢出时才预留，而"溢出与否"恰恰就是两个标签页之间的那点差别——`auto` 的写法只是把缺陷重述一遍，并不能修掉它。
+
+overlay 状态是一个没有任何东西会去滚动它的滚动容器：视图把它填满（`flex: 1 1 0`，且自带裁剪），座位不在常规流中，因此没有任何手势与裁剪行为发生变化。变化的是引擎会认哪些声明。WebKit 对 `overflow-y: auto` 的盒子应用 `scrollbar-gutter`，对 hidden 的盒子则忽略它——这是在本应用 composer 自身的图层上实测所得，并记录于 [composer 滚动容器记录](2026-07-31-composer-text-layers-share-one-scrollport.md)——所以把预留留在一个 hidden 盒子上，会在 Chromium 上成立，在 Safari 上悄无声息地不成立。
+
+横向轴是显式声明的，而不是交给推导：单轴滚动的盒子会把另一轴的 `visible` 计算为 `auto`，于是只要某个视图的内容第一次伸出列外，它就会长出自己的横向滚动条。
+
+这条预留之所以值回它的代价，前提是滚动条在这里确实占布局空间——这并非浏览器的默认行为，而是本客户端的选择：ui-theme 的样式表给 `::-webkit-scrollbar` 声明了宽度（[滚动条主题化](2026-07-28-themed-scrollbars-and-reserved-gutter.md)），侧边栏的会话列表也正是出于同一原因预留了自己的滚动条槽。
+
+## 曾考虑的替代方案
+
+**把 overlay 座位按滚动条宽度内缩。** 这是对该缺陷最窄的一种解读——两种状态差 8px，那就从一侧减去 8px。之所以否决，是因为这个数字属于引擎而不属于我们：WebKit 路径绘制样式表里的 8px 滚动条，Firefox 路径绘制 `scrollbar-width: thin` 解析出的宽度，硬编码的内缩会让两种状态在 Chromium 上对齐、在别处继续漂移。滚动条槽是请引擎按它自己那条滚动条的宽度去预留，无论那是多少。
+
+**保留 `overflow: hidden`，只加 `scrollbar-gutter: stable`。** 单行版本。它能在浏览器车道所用的引擎上修掉可见症状，却把症状原封不动留在 Safari 上，而且任何测试都不会失败——这正是改动的后一半所要防的失效模式。
+
+**让 Chat 的 composer 座位也移出滚动容器，使 overlay 的几何成为唯一的几何。** 这是从根上删掉差异，而不是调和它，代价是放弃一项刻意的性质：sticky 座位位于滚动流之内，因此在 composer 上滚轮会带动对话记录（[sticky composer](2026-07-29-sticky-composer-conversation-scroll.md)），其上方的渐隐遮罩也由座位自身的背景绘制。两者都是有主、有覆盖的既有行为；为了消除 8px 的不对称而重建它们，是更大的改动而非更小的。
+
+**给会话列加上一条滚动条宽度的内边距，而不是预留滚动条槽。** 内边距无论是否存在滚动条都会生效，因此在每种状态下都无条件付出这份宽度，而且它把一个由引擎在布局期决定的值钉死在样式表里。否决理由与侧边栏列表当初否决它时相同。
+
+## 后果
+
+- Chat 的内容列永久变窄 8px——hero 态与对话记录尚短、根本不绘制滚动条时同样如此。这就是这笔交易：以最宽的列换取卡片在任何内容高度下都只有一个位置。
+- 一条声明覆盖三种切换，因为这三者本就是同一个差异：Chat ↔ Trajectory、Chat 内部的短对话 ↔ 可滚动对话，以及 hero ↔ 第一个可滚动轮次。
+- overlay 状态现在是一个滚动容器。今天其中没有任何内容会溢出；将来若有视图允许自身内容超出会话列，这个盒子会滚动而不是裁剪，那个视图就需要像 Trajectory 视图那样自带裁剪。
+- 提交的 golden 记录了预留的带宽，因此样式表中 `::-webkit-scrollbar` 宽度的变化——决定这条预留有多宽的那个值——会在本场景中与在侧边栏场景中一样，以可评审的 diff 形式出现。
+
+## 测试
+
+`apps/web/tests/composer-tab-geometry.e2e.ts` 在两个标签页下测量输入卡片的矩形，分别取卡片处于宽度上限的视口与卡片随列收缩的视口，并断言这两个矩形是同一个矩形。只有真实引擎能报告这件事：jsdom 给每个元素的盒子尺寸都是零，也没有滚动条，因此单元测试只能断言那些声明存在，无法断言两种状态落在同一位置。出于同一原因，本次没有附带读取 CSS 文本的单元测试——它只会把声明复述一遍，并不会补上浏览器车道尚未确立的事实。
+
+该场景启动 chromium 时去掉了 Playwright 默认的 `--hide-scrollbars`，这一点是承重的：带上该参数时滚动条不占任何布局宽度，两个标签页在改动前后同样一致，文件中的每一处比较都会空洞地通过。实测：带上该参数时，改动前的层叠让两侧带宽都是 0；去掉它则是 8 与 0。
+
+随后，改动前的层叠会被注入页面——滚动容器上 `scrollbar-gutter: auto`，overlay 分支上 `overflow: hidden`——并在其下测量同样的两个标签页，这正是把"卡片确实没动"与"标签页切换根本没到达布局"区分开的那一步。它把上报的症状复现为一个数字：每条边 4px，恰是 8px 带宽的一半。golden 把这份对照与修复后的状态并排记录，因此 fixture 承载的是这次改动所消除的那个差值，而不仅仅是它的缺席。

+# Agent Note: Workspace New Session reuse hijacked cwd-matching unaccounted blank sessions
+
+Status: implemented
+
+English | [中文](2026-08-05-workspace-blank-session-reuse-membership.zh.md)
+
+## Problem
+
+Clicking the `+` on a Workspace group in the sidebar sometimes opened a session that the sidebar showed under Ungrouped instead of under the clicked Workspace — "entered a new session but the Workspace was not selected". The failure was specific to Workspaces registered at the directory the CLI runs from (in practice the harness checkout itself, i.e. `defaults.cwd = process.cwd()`), and appeared once a CLI-born blank session existed there.
+
+Root cause: `connectWorkspace`'s blank-session reuse scanned the session list mirror on `cwd` equality alone. The host's own membership rule requires **both** an id in the Workspace account (`sessionIds`) **and** a session header whose canonical cwd equals the Workspace path ([Workspace UI product flow](../feature/2026-07-25-workspace-ui-product-flow.md)); a cwd match without the account slot is exactly the Ungrouped case. The reuse scan ignored the account slot, so any **live blank** session whose cwd matched qualified — including `main-session-*` sessions the CLI/TUI/headless entry points birth at the host cwd (`session.create({})` falls back to `defaults.cwd` and never attaches to a Workspace). When such a session was live and blank (no `turn/start` yet), the next `+` click on a Workspace registered at that path reused it and navigation opened a session no grouping surface can show under that Workspace. Workspaces at other paths were unaffected because no unaccounted blank sessions accumulate there; the host-cwd Workspace accumulated one per CLI run.
+
+## Decision
+
+The reuse scan now requires workspace membership: `blank` AND `summary.cwd === workspace.path` AND `workspace.sessionIds.includes(summary.id)` AND not archived. A cwd-only match falls through to `session.create({ workspaceId })`, which attaches the fresh session so the Workspace owns it — the same arm the flow already used for "no blank session exists".
+
+## Alternatives considered
+
+**Adopt the stray instead of minting.** `session.create({ workspaceId })` could attach a cwd-matching unaccounted blank session. Rejected: silently attaching CLI-born sessions to a Workspace crosses the account boundary by surprise, and the client cannot distinguish "stray" from "the Workspace's own blank" without the membership view — which is the fix itself.
+
+**Attach on reuse via a new wire operation.** Requires a `workspace.attachSession` RPC in the navigation hot path and would still render the session under Ungrouped for a frame; no product need justifies the surface.
+
+## Consequences
+
+Stray blank sessions remain visible in Ungrouped (the user can still open them) but are never hijacked by a Workspace's New Session flow. Membership is a new condition on the reuse scan, and it has one observable stale-mirror edge: in the window where the session mirror is fresh but the Workspace account frame lags, the Workspace's own member blank can fail the membership check and a duplicate blank is minted where the old code reused — a second `New Session` row under that Workspace rather than the old failure shape (a session that no grouping surface shows). Both windows are transient and the per-Workspace coalescing still prevents duplicate creates racing one another. No host, wire, or durable-format change.
+
+## Testing
+
+`packages/client/runtime/tests/workspaces-service.spec.ts` covers the four outcomes: a member blank session is reused (no create RPC); a stray blank with matching cwd is **not** reused and a fresh accounted session is created (regression case); an archived blank is not reused; a rejected first prompt keeps a member blank eligible. The full client suite (`pnpm run test:gui`) stays green.

+# Agent Note：工作区新建会话复用了 cwd 匹配但未入账的空白会话
+
+状态：已实现
+
+[English](2026-08-05-workspace-blank-session-reuse-membership.md) | 中文
+
+## 问题
+
+在侧边栏某个工作区分组的 `+` 上创建会话时，有时会进入一个新会话，但侧边栏把它显示在「未分组」而不是点击的那个工作区下——「进入了新会话，但工作区没有被选中」。故障只出现在注册在 CLI 运行目录（即 `defaults.cwd = process.cwd()`，实际场景里就是 harness 检出目录本身）上的工作区，并且一旦该目录下存在 CLI 创建的空白会话就会出现。
+
+根因：`connectWorkspace` 的空白会话复用扫描只按 `cwd` 相等匹配会话列表镜像。host 自己的成员规则要求**同时**满足：会话 id 在工作区账户（`sessionIds`）中，**且**会话 header 的规范化 cwd 等于工作区路径（[Workspace UI product flow](../feature/2026-07-25-workspace-ui-product-flow.md)）；只有 cwd 匹配而没有账户槽位的恰恰就是「未分组」的情形。复用扫描忽略了账户槽位，因此任何 cwd 匹配的**在线空白**会话都会被选中——包括 CLI/TUI/headless 入口在 host cwd 创建的 `main-session-*` 会话（`session.create({})` 回退到 `defaults.cwd`，从不挂到任何工作区）。当这样的会话在线且空白（尚无 `turn/start`）时，下一次在该路径注册的工作区上点击 `+` 就会复用它，导航打开的是一个任何分组表面都无法显示在该工作区下的会话。其他路径的工作区不受影响，因为那里不会积累未入账的空白会话；而 host-cwd 工作区每次 CLI 运行都会积累一个。
+
+## 决定
+
+复用扫描现在要求工作区成员关系：`blank` 且 `summary.cwd === workspace.path` 且 `workspace.sessionIds.includes(summary.id)` 且未归档。仅 cwd 匹配的情况落到 `session.create({ workspaceId })`，创建并挂接新会话，使工作区拥有它——这与流程中「不存在空白会话」时的既有分支完全相同。
+
+## 曾考虑的替代方案
+
+**收养游离会话而不是新建。** 让 `session.create({ workspaceId })` 挂接一个 cwd 匹配但未入账的空白会话。否决：静默地把 CLI 创建的会话挂到工作区上，越过了账户边界，令人意外；而且客户端没有成员视图就无法区分「游离会话」与「工作区自己的空白会话」——而成员视图本身就是本次修复。
+
+**复用时就地挂接，新增一条 wire 操作。** 需要在导航热路径上新增 `workspace.attachSession` RPC，并且会话仍会有一帧显示在「未分组」；没有产品需求值得新增这个表面。
+
+## 后果
+
+游离空白会话仍显示在「未分组」（用户仍可手动打开），但不再被某个工作区的新建会话流程劫持。成员校验是复用扫描的新增条件，有一个可观察的镜像滞后边界：在会话镜像已新而工作区账户帧滞后的窗口里，工作区自己的成员空白会话可能因成员校验失败而错过复用，多创建一个空白——表现为该工作区下出现第二个「新会话」行，与旧故障形态（打开一个任何分组表面都无法显示的会话）不同。两个窗口都是瞬态的，按工作区的合并逻辑仍然防止并发创建互相竞争。无 host、wire 或持久化格式变更。
+
+## 测试
+
+`packages/client/runtime/tests/workspaces-service.spec.ts` 覆盖四种结果：成员空白会话被复用（无 create RPC）；cwd 匹配但非成员的游离空白会话**不被**复用、改为创建全新入账会话（回归用例）；已归档空白会话不被复用；首次 prompt 被拒后成员空白会话仍可复用。完整客户端套件（`pnpm run test:gui`）保持绿色。

 The Web Host reuses `installAgentLlmTarget` for every created or resumed agent. The provider/model/reasoning target starts from the latest `request/header` when the session has used a model, otherwise from the Host default route. `session.selectModel` changes the session-local mutable target, and prompt assembly captures it with request routing; a switch during a running step therefore applies to the next assembled step. The next consumed target persists through the existing full `request/header` snapshot, while a choice that has not reached a request remains process-local.

The directory is built dynamically from the LLM registry and grouped by provider; each listed model's exact metadata adds adapter-owned reasoning effort ids, names, descriptions, and optional default.

Catalog membership stays advisory: the current model is inserted as an unlisted row when its registered provider omits it, while exact resolution decides whether a route and explicit effort are available.

Provider catalogs and exact metadata load concurrently by provider and fail independently, so successful groups remain usable alongside retryable failure records. Catalog membership stays advisory: `session.models.current` is returned independently and can remain routable when absent from every group, but the Host does not synthesize an unlisted row after its provider stops advertising it. The two surfaces answer that state differently on purpose: the TUI still renders the unlisted current model as its own row and marks it current, while Web shows the unset trigger label and asks for a replacement. Web is the surface where a catalog is edited, so a target the user just deleted should read as a decision to make rather than a selection to keep; the TUI, which only picks from what exists, has no such edit to reconcile. The cost is real and accepted — a Web composer showing the unset label can still send to the routed target — and the divergence is deliberate, not a missed migration. Exact resolution decides whether a route and explicit effort are available. Selection uses `resolveCallConfig` to reject unsupported effort ids and materialize an adapter-configured default before updating the target.
 
 The browser `ModelService` owns one `ModelDirectory` per live session. Its snapshot contains the current complete target, grouped catalog, provider failures, operation error, and `idle`/`loading`/`ready`/`selecting`/`error` state. Mounting primes the trigger label and each menu open refreshes the directory. Directory and selection calls share an operation generation so older responses cannot replace a newer result; connection reset discards the process-local projection before restoring the Host target. Failures retain the previous current target and usable groups.

Its compact trigger displays the catalog model name and effective reasoning label, falling back to ids when metadata is absent.

 ## Problem

+Standing docs accumulated repeated rules, retold incidents, duplicated package maps, and stale Agent Note summaries despite existing writing guidance. That guidance also did not define how a document's place in the hierarchy limits its scope or how ordered teaching differs from lookup-oriented material. Because review alone did not prevent that growth, the repository needed a mechanical budget alongside its documentation taxonomy.
 
 ## Decision
 
-- **A tier taxonomy with one home per fact.** [docs/AGENTS.md](../../../../docs/AGENTS.md) is the documentation standard: it assigns every Markdown tier a single job (standing orders, system map, type catalog, decision records, incident stories, how-tos, per-package contracts, generated catalogs, workflows), forbids restating a fact outside its home tier (link instead), and carries the slop checklist used when writing or reviewing any doc.
+- **Structure follows the documentation tree.** [docs/AGENTS.md](../../../../docs/AGENTS.md) is the documentation standard: a document owns detail about its subject, summarizes only the purpose, responsibility, and high-level behavior of direct children, and links to deeper owners. [Agent Notes](../../README.md) remain outside this structural contract. Every human-facing document is a tutorial with an ordered outcome or a reference with an explicit lookup scope; a [postmortem](../../../../docs/postmortem/README.md) is an incident-scoped reference whose chronology records evidence. Tutorials introduce concepts in prerequisite order for the reader's starting knowledge.
+- **A tier taxonomy with one home per fact.** The standard assigns every Markdown tier one job, forbids restating a fact outside its home tier, and carries the slop checklist used when writing or reviewing any doc.
 - **A narrow, hard budget gate.** [scripts/verify-doc-budgets.ts](../../../../scripts/verify-doc-budgets.ts) joins `doc-sync`: every doc listed in [scripts/doc-budgets.manifest.json](../../../../scripts/doc-budgets.manifest.json) must stay under its word ceiling (`wc -w` semantics, whole file), and a budgeted file that is missing fails the gate so a rename cannot silently orphan its budget. Scope is deliberately only the accretion-prone standing docs — the root and subtree `AGENTS.md` files, `architecture.md`, `packages/README.md`, and the standing policy docs they evict content into (`docs/testing.md`, `docs/defensive-patterns.md`). Reference docs, Agent Notes, and package READMEs are unbudgeted: length is legitimate there when every row is a fact, and review plus the slop checklist govern them.
-- **Ceilings are an enforcement frontier that ratchets.** A ceiling sits at least 5% above the doc's current size — working headroom, so routine wording edits pass while real growth still trips the gate — and ratchets down, keeping that margin, as the doc is brought to its target budget (root `AGENTS.md` ≤ 1,500 words; `architecture.md` ≤ 1,800; subtree `AGENTS.md` ≤ 600; `packages/README.md` ≤ 600). When the gate goes red the fix is to relocate or condense per the taxonomy; raising a ceiling is permitted only with explicit justification in the PR description, the manifest diff being the reviewable act.
+- **Ceilings are an enforcement frontier that ratchets.** A doc at or below its target keeps at least 5% headroom as its ceiling ratchets down; a doc above target keeps a frozen ceiling that prevents growth until it reaches the target (root `AGENTS.md` ≤ 1,600 words; `architecture.md` ≤ 1,800; subtree `AGENTS.md` ≤ 600 except `packages/AGENTS.md` ≤ 650 and `docs/AGENTS.md` ≤ 1,250; `packages/README.md` ≤ 600). When the gate goes red, relocate or condense; raise a ceiling only with explicit PR justification.
 - **A thin workflow skill, contracts in docs.** [.agents/skills/dsh-doc-standards](../../../skills/dsh-doc-standards/SKILL.md) carries the placement/audit/red-gate workflow and defers to the standard as its source of truth, the same split as [dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md) over the i18n contract.

-- **范围窄且严格的预算门禁。**[scripts/verify-doc-budgets.ts](../../../../scripts/verify-doc-budgets.ts) 接入 `doc-sync`：[scripts/doc-budgets.manifest.json](../../../../scripts/doc-budgets.manifest.json) 列出的每份文档都不得超过其词数上限（采用 `wc -w` 语义，统计整个文件）；预算内文件缺失也会使门禁失败，使文件重命名无法悄然摆脱预算约束。范围刻意只涵盖容易膨胀的常设文档——根目录和子树中的 `AGENTS.md` 文件、`architecture.md`、`packages/README.md`，以及它们将内容移入的常设策略文档（`docs/testing.md`、`docs/defensive-patterns.md`）。参考文档、Agent Note 和包 README 不设预算：只要每一行都是事实，长度在这些位置就是合理的；评审和赘余检查清单负责约束它们。
-- **上限是会逐步收紧的执行红线。** 上限设定为文档当前词数的至少 105%（留出工作余量，使日常措辞调整能通过，而真正的膨胀仍会触发门禁），并随着文档被精简到目标预算而同步下调、保持该余量（根 `AGENTS.md` ≤ 1,500 词；`architecture.md` ≤ 1,800；子树 `AGENTS.md` ≤ 600；`packages/README.md` ≤ 600）。门禁变红时，修复方式是按分类体系迁移或压缩内容；只有在 PR（Pull Request）描述中给出明确理由时才允许提高上限，manifest（元数据清单）的 diff 本身就是可供评审的变更。
-- **精简的工作流 skill（技能），契约归文档。**[.agents/skills/dsh-doc-standards](../../../skills/dsh-doc-standards/SKILL.md) 承载文档放置、审计和门禁失败处理工作流，并以文档标准为真源，与 [dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md) 和 i18n 契约之间的分工相同。
+- **结构遵循文档树。**[docs/AGENTS.md](../../../../docs/AGENTS.md) 是文档标准：文档负责承载其主题的详细内容，仅概述直接子项的目的、职责和高层行为，并链接到更深层内容的归属文档。[Agent Note](../../README.md) 仍不受这一结构契约约束。每份面向人的文档要么是按顺序引导读者达成结果的教程（tutorial），要么是查阅范围明确的参考文档（reference）；[事故复盘（postmortem）](../../../../docs/postmortem/README.md) 是范围限定于单个事件的参考文档，其时间线记录证据。教程结合读者的起始知识，按前置依赖顺序介绍概念。

 ## 后果
 
-- 向受预算约束的文档添加内容现在需要腾挪空间：将新增内容迁移到其分类体系归属地并留下链接，或压缩现有行文来腾出空间。只增不减会导致 CI 失败。
-- 精简到目标预算的重写以堆叠的后续 PR 落地，每次合并时同步下调 manifest 中的上限；在各自落地之前，文档冻结的上限仅阻止进一步膨胀。
-- 词数是一个粗糙的代理指标，这是有意接受的：它无法判断质量，但它在内容被添加的那一刻强制触发迁移决策，而那正是作者拥有足够上下文来正确放置内容的时刻。

+- 结构评审先检查归属关系和文档形式，再进行句子层面的编辑，使较低层级的细节迁移到其归属文档，而不是在错误的位置加以润色。
