+`Session`'s constructor appends the log-only `session/end-seed` event immediately after an explicitly supplied constructor seed, including an empty one, as the seeded session's first live write at the seq `firstLiveSeq` names. The event is the durable projection of that field: `firstLiveSeq` answers where this lifecycle's writes start for a consumer holding the object, while `session/end-seed` answers the same question for one holding only stored bytes. Its payload is empty — position and `time` carry the whole meaning — and it is not a `SurfaceEventType`, so it produces no message and cannot perturb derived history. The seq-0 marker distinguishes an empty resumed session from a genuinely fresh session, preventing new-session defaults from being applied during resume.
 
 A bracket owner reads it positionally: an unmatched opening marker before `session/end-seed` has a smaller seq, came from the constructor seed, and belongs to a lifecycle that has ended. Core writes the boundary and reads nothing from it; each bracket's vocabulary stays with its owning plugin, so no core predicate helper ships without a consumer to shape it.
 
 The constructor is the placement because it is the single waist every seeded session passes through. All six entry points reach it: `agents.resume()`, config-driven startup on a persisted id (`restoreOrCreateConfigured`), `sessions.fork()`, a subagent fork child, `coordinator.adopt()`'s live-prefix path, and a bare `sessions.create(id, {seed})`. A boundary written at persistence load would miss both fork paths — and a forked child inheriting a still-running parent's open `compact/start` is precisely the case that must be classifiable. A boundary written at loop start would miss `fork()` and `adopt()`, and would have to fire on `SessionStartSource: 'startup'`, which is what a fork child publishes, so that field would stop discriminating.
 
-Two guards keep the marker from becoming noise. An empty seed writes nothing because there is no seed to end. A seed already ending in one is not re-marked, which makes the write idempotent. Idempotence is load-bearing rather than tidiness — `agentFor()` resumes a cold session on first touch, so merely opening one in a client is a pickup, and without the guard browsing would grow a log by one event per visit.

 Bought: one boundary, written in one place, correct for all six seeded-start paths — including the fork gap the persistence-layer version could not reach. The persistence packages keep a pure read path. `firstLiveSeq` gains a durable twin rather than a second, competing notion of the same boundary.
 
-Cost: a seeded session's log is one event longer, which moved seq expectations in tests across nine packages (session, agent-loop, persistence contract, jsonl, session-query, session-title, subagent-inprocess, telemetry, token-meter). Two of those updates are load-bearing rather than mechanical: telemetry's adoption tests now assert the boundary IS exported, because it is this lifecycle's own write, and the property suite's replay invariant is restated as "seed reproduced verbatim, plus one log-only boundary" with idempotence added as its own property.

 `session/end-seed` joins the on-disk vocabulary. Under the pre-release stance (`SESSION_FORMAT_VERSION` pinned at `0`, no compatibility promise) older logs simply lack it, and a log without a boundary correctly classifies nothing as constructor-seed history.

 括号所有方按位置读取它：在 `session/end-seed` 之前的未配对开启标记具有更小的 seq，来自构造种子，并且属于一个已结束的生命周期。核心写入该边界但不从中读取任何内容；每个括号的词汇表仍归其所属插件，因此在没有消费方来塑形之前，核心不会先发布谓词辅助函数。
 
 选择构造函数，是因为它是每一个带种子会话都必经的唯一收窄处。全部六个入口都会到达它：`agents.resume()`、在已持久化 id 上的配置驱动启动（`restoreOrCreateConfigured`）、`sessions.fork()`、子代理 fork 子会话、`coordinator.adopt()` 的实时前缀路径，以及裸的 `sessions.create(id, {seed})`。在持久化加载时写入的边界会漏掉两条 fork 路径——而一个继承了仍在运行的父会话开放 `compact/start` 的 fork 子会话，恰恰是必须可判定的场景。在 loop 启动时写入的边界会漏掉 `fork()` 与 `adopt()`，并且不得不在 `SessionStartSource: 'startup'` 上触发——那正是 fork 子会话发布的取值，于是该字段将不再具有区分力。
 
-两条守卫让这个标记不至于变成噪声。空种子不写入任何内容，因为没有种子需要结束。种子本身已以该事件结尾时不会重复标记，这让写入具备幂等性。幂等性是承重的，而不是为了整洁——`agentFor()` 会在首次触碰时恢复一个冷会话，因此在客户端里仅仅打开一个会话就是一次接手；没有这条守卫，浏览会让日志每访问一次就增长一个事件。

 **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.

Full access reduces confirmation steps and lets the agent run sensitive operations, modify files, or execute external commands, so an accidental pick armed the most dangerous preset with no deliberate acknowledgement step.

+**Every permission picker gates `danger-full-access` behind the shared in-page `RiskConfirmation` dialog whose enabling action stays disabled until an explicit acknowledgement checkbox is checked; the preset renders under the product label `Full access`; every dismissal path submits nothing.**
 
 - `RiskConfirmation` (ui-primitives) is a controlled Modal composition: title, description, acknowledgement checkbox, cancel, and a confirm button disabled until `acknowledged`. It stays an in-page dialog — the Modal portals to this document's body and never opens a native or separate browser window that could land on another display. `Modal` gains a `contentClassName` seat so the warning body scrolls inside constrained mobile/landscape viewports while the action row stays fixed.
 - The composer chip (`PermissionSelect`, ui-conversation) intercepts a Full-access pick before the `/permission` submit: `confirmation`/`acknowledged` component state opens the dialog, confirm submits `/permission danger-full-access` through the same injected `command` path as every other pick, and cancel/Escape/close/mask leave the current preset untouched with the checkbox reset. The confirmation revokes itself when the session locks (`locked`/value-absent effect) and resets across task switches (`key={sessionId}` remount). Copy rides the standard `conversation` locale seat as `access.confirm.*` keys.
 - The `/permission` popup (ui-permission over the ui-command shell) gates through data, not a second dialog implementation: `SelectOption` grows an optional `confirmation` payload, the popup controller owns the `confirming`/`acknowledged` state transitions, and `PopupSelectView` swaps the picker card for the same `RiskConfirmation` while a gated option is pending.
-- `Full access` intentionally overrides the kebab-to-title display transform on both surfaces (option rows, trigger label, settled command rows keep the machine name on the wire); the warning body remains locale-aware in Chinese and English.
+- The General-settings Permission row uses the same controlled `RiskConfirmation` before persisting Full access as the default for later sessions. Its warning names that future-session lifetime; cancel, Escape, close, and mask dismissal leave the stored default untouched.
+- `Full access` intentionally overrides the kebab-to-title display transform in every picker; command and Settings writes keep the machine name on the wire, and each warning body remains locale-aware in Chinese and English.
 
 ## Alternatives considered
 
 **A native/OS or separate-window confirmation.** Rejected: the dialog must stay inside the current WebUI window; a second window can appear on another display and detaches the decision from the page state it guards.
 
-**One shared locale namespace for both surfaces' safety copy.** Rejected: the ui-permission bundle and ui-conversation load independently, so each registers the same copy under its own namespace (`permission.access` beside the conversation dictionary); the duplication is fenced with an explanatory `jscpd:ignore` block rather than a cross-bundle import.
+**One shared locale namespace for every surface's safety copy.** Rejected: the ui-permission bundle and ui-conversation load independently, while the Settings warning names a different future-session lifetime. Each bundle owns its copy, and ui-permission keeps the popup and Settings dictionaries separate rather than importing across bundle boundaries.
 
 **Gating in the host/permission backend.** Out of scope by design: the change is browser-client confirmation flow only; backend permission semantics, defaults, and the safer presets' one-click behavior are unchanged.
 
 ## Consequences
 
-Every visible GUI path into Full access now requires a deliberate, informed acknowledgement, at the cost of one extra dialog step for users who genuinely want the preset. New pickers reuse the gate by attaching a `confirmation` payload (popup path) or the chip's state machine (composer path) instead of inventing bespoke dialogs.

-**两个权限面都把 `danger-full-access` 关进同一个共享的页面内 `RiskConfirmation` 对话框：启用按钮在用户勾选明确的风险确认复选框前保持禁用；预设以产品标签 `Full access` 展示；所有取消路径都不提交任何命令。**

 - `RiskConfirmation`（ui-primitives）是受控的 Modal 组合：标题、说明、确认复选框、取消，以及 `acknowledged` 勾选前禁用的确认按钮。它始终是页面内对话框——Modal portal 到本文档 body，绝不打开可能落在另一块显示器上的原生或独立浏览器窗口。`Modal` 新增 `contentClassName` 座位，令警示正文在受限的移动端／横屏视口内滚动，动作行保持固定。
 - 编辑器 chip（ui-conversation 的 `PermissionSelect`）在 `/permission` 提交前拦截 Full-access 选择：`confirmation`/`acknowledged` 组件状态打开对话框，确认后经与其他选择完全相同的注入 `command` 通道提交 `/permission danger-full-access`；取消、Escape、关闭与遮罩点击均保持当前预设不变并重置复选框。会话锁定时确认自行撤销（`locked`／值缺席 effect），切换任务时随 `key={sessionId}` 重挂载而重置。文案经标准 `conversation` locale 座位以 `access.confirm.*` 键供给。
 - `/permission` popup（ui-permission 骑在 ui-command 外壳上）以数据而非第二套对话框实现完成把关：`SelectOption` 新增可选的 `confirmation` 载荷，popup 控制器拥有 `confirming`/`acknowledged` 状态迁移，`PopupSelectView` 在门控选项未决期间把选择卡换成同一个 `RiskConfirmation`。
-- `Full access` 在两个面上有意覆盖 kebab 转 Title Case 的显示变换（选项行、触发器标签；落定的命令行仍在 wire 上保留机器名）；警示正文保持中英文 locale 感知。
+- 「通用」设置中的「权限」行在把 Full access 持久化为后续会话的默认值前，也使用同一个受控 `RiskConfirmation`。警示会明确说明该设置只影响后续会话；取消、Escape、关闭与点击遮罩均不会改动已存默认值。
+- `Full access` 在每个选择器中都有意覆盖 kebab 转 Title Case 的显示变换；命令与 Settings 写入在 wire 上保留机器名，每份警示正文都保持中英文 locale 感知。
 
 ## Alternatives considered
 
 **原生／操作系统或独立窗口确认。** 已拒：对话框必须留在当前 WebUI 窗口内；第二个窗口可能出现在另一块显示器上，使决策脱离其守护的页面状态。
 
-**两个面共享一个安全文案 locale namespace。** 已拒：ui-permission bundle 与 ui-conversation 可独立加载，故各自在自己的 namespace 下注册同一份文案（`permission.access` 与 conversation 词典并立）；这处重复以带说明的 `jscpd:ignore` 块圈护，而非跨 bundle import。
+**每个面的安全文案共享一个 locale namespace。** 已拒：ui-permission bundle 与 ui-conversation 可独立加载，而 Settings 警示说明的是另一种只影响后续会话的生效周期。每个 bundle 各自拥有文案，ui-permission 也将 popup 与 Settings 词典分开，而非跨 bundle 边界 import。
 
 **在 host／权限后端把关。** 设计上即出界：本变更只涉浏览器客户端确认流；后端权限语义、默认值与更安全预设的一键行为均不变。
 
 ## Consequences
 
-进入 Full access 的每条可见 GUI 路径现在都要求刻意且知情的确认，代价是真想启用该预设的用户多一步对话框。新的选择器复用此门：popup 路径挂 `confirmation` 载荷、编辑器路径走 chip 的状态机，而不是各造对话框。验收：`input-bar.spec.tsx` 中编辑器流的四个门控用例、`popup-view.spec.tsx` 与 `popup.spec.ts` 的 popup 门、`atoms.spec.tsx` 的 Modal/RiskConfirmation 契约，以及组装态 `access-confirmation` web e2e——其 golden 钉住产品默认中文词典文案。

+# Agent Note: Permission Settings default for new sessions
+
+Status: implemented
+
+English | [中文](2026-07-31-permission-default-for-new-sessions.zh.md)
+
+## Problem
+
+The Web General-settings page displayed Permission as a disabled skeleton even though `dsh-permission` already owned the preset table and current-session switch path. The Settings seam could persist a plugin-owned value, but the Web settings API exposed only configurable LLM-provider namespaces. More importantly, treating a user preference as a live global permission would make an existing session's execution policy change outside its durable log.
+
+## Decision
+
+`dsh-permission` owns a `permission` Settings namespace with one `defaultPreset` field. Its base value is `Config.defaultPreset`, or the preset matching the composed sandbox and approval defaults when the config omits it. The schema derives its enum from the configured preset table, so Settings validates stored values and the Web client discovers the deployment's actual choices without duplicating them.
+
+The service reads the current Settings value synchronously at `session/created`. A genuinely fresh session receives three explicit events: `permission/preset`, `sandbox/mode`, and `approval/policy`. Those facts pin the permission selected at creation, so a later Settings change affects only later sessions. A seeded or partially initialized session preserves its effective knobs and receives only missing facts; it never adopts the latest user default while resuming. `Session` marks even an explicitly empty constructor seed with `session/end-seed`, so an empty persisted log cannot be mistaken for a fresh session.
+
+The existing `/permission` command and `permissions` projection remain the current-session path. The browser plugin now contributes the Permission row to `settings.general.item`, reads the dynamic enum from the redacted Settings descriptor, and writes only `defaultPreset` through a revision-checked `settings.mutate`. The row injects its observable through the slot `hooks` compartment instead of binding a renderer-specific hook, and the Permission service sweeps already-live sessions when it mounts so HMR cannot leave an unpinned session. The ownerless General-settings package contributes no placeholder rows.
+
+ApiProxy explicitly adds `permission` to its Web settings allowlist beside the configurable-provider namespaces. This is a local boundary decision, not a general registration flag or a `local-client` access model: registering another Settings namespace still does not expose it. Permission changes emit `host/settings-changed` but not `host/models-changed`.
+
+## Consequences
+
+Changing Permission in Settings updates `settings.yaml` and the selector immediately, but does not alter the open session. Every later session is reconstructable from its three pinned permission facts, including after the user changes the default again or the process restarts. Deployments whose composed sandbox and approval defaults match no preset must configure `defaultPreset` explicitly.
+
+The assembled Web snapshot now contains a functional Permission selector. Its keyless browser scenario writes `read-only`, verifies an existing `danger-full-access` session is unchanged, and verifies a subsequently created session starts with the read-only event triplet.
+
+## Alternatives considered
+
+**Apply the Settings value live to every session.** Rejected because execution policy would change without a session event and replay could not reconstruct which permission governed an earlier tool call.
+
+**Record only `permission/preset` on creation.** Rejected because sandbox and approval are independently owned whole-value knobs; pinning all three facts keeps their consumers independent of future composition-default changes.
+
+**Expose all Settings registrations, or add a generic `local-client` declaration.** Rejected for this change because it expands a security boundary and the Settings contract beyond the one requested preference. The explicit `permission` allowlist entry is sufficient and leaves future namespaces to make their own exposure decision.
+
+**Apply the latest default while resuming a seeded session.** Rejected because resume must preserve the session's prior effective execution policy; missing legacy facts are materialized from that policy instead.

+# Agent Note: 新会话的权限 Settings 默认值
+
+Status: implemented
+
+[English](2026-07-31-permission-default-for-new-sessions.md) | 中文
+
+## 问题
+
+Web「通用」设置页将「权限」显示为禁用的骨架控件，尽管 `dsh-permission` 已经拥有 preset 表和当前会话的切换路径。Settings seam 可以持久化由插件拥有的值，但 Web Settings API 只暴露可配置 LLM 提供方的 namespace。更重要的是，如果把用户偏好当成实时生效的全局权限，现有会话的执行策略就会在其持久日志之外发生变化。
+
+## 决策
+
+`dsh-permission` 拥有一个 `permission` Settings namespace，其中只有 `defaultPreset` 字段。它的基础值是 `Config.defaultPreset`；省略该配置时，则使用与组合后的沙箱和审批默认值匹配的 preset。schema 的 enum 从已配置的 preset 表派生，因此 Settings 既能校验已存储的值，Web 客户端也能发现部署中的实际选项，而无需重复定义。
+
+服务会在 `session/created` 时同步读取当前 Settings 值。真正的新会话会收到三个显式事件：`permission/preset`、`sandbox/mode` 和 `approval/policy`。这些事实将创建时选中的权限固定下来，因此后续 Settings 变更只影响之后的会话。带 seed 或只完成部分初始化的会话会保留其有效调节项，只补齐缺失的事实；恢复时绝不会采用最新的用户默认值。`Session` 甚至会用 `session/end-seed` 标记显式为空的构造器 seed，因此不能把空的持久化日志误认为新会话。
+
+现有 `/permission` 命令和 `permissions` 投影仍是当前会话的操作路径。浏览器插件现在向 `settings.general.item` 贡献「权限」行，从脱敏后的 Settings 描述符读取动态 enum，并只通过经过 revision 校验的 `settings.mutate` 写入 `defaultPreset`。该行通过 slot 的 `hooks` 格注入 observable，而不是绑定渲染器专用钩子；权限服务挂载时会遍历并固定所有已存活会话，因此 HMR（热模块替换）不会遗留未固定的会话。无归属的「通用」设置包不贡献任何占位行。
+
+ApiProxy 在可配置提供方 namespace 之外，将 `permission` 显式加入 Web Settings allowlist。这是局部的边界决策，而不是通用注册标志或 `local-client` 访问模型：注册其他 Settings namespace 仍不会将其暴露。权限变更会发出 `host/settings-changed`，但不会发出 `host/models-changed`。
+
+## 后果
+
+在 Settings 中更改「权限」会立即更新 `settings.yaml` 和选择器，但不会改变已打开的会话。之后的每个会话都可以从三个已固定的权限事实中重建，即使用户再次更改默认值或进程重启也不受影响。如果部署中组合后的沙箱和审批默认值与任何 preset 都不匹配，则必须显式配置 `defaultPreset`。
+
+组装后的 Web 快照现在包含功能完整的「权限」选择器。其无密钥浏览器场景会写入 `read-only`，验证现有的 `danger-full-access` 会话保持不变，并验证随后创建的会话以 read-only 事件三元组启动。
+
+## 曾考虑的替代方案
+
+**将 Settings 值实时应用于每个会话。** 不予采纳，因为执行策略会在没有会话事件的情况下改变，重放也无法重建先前工具调用采用了哪种权限。
+
+**创建时只记录 `permission/preset`。** 不予采纳，因为沙箱和审批是由不同组件独立拥有的全量值调节项；固定全部三个事实，可以让其消费方不依赖未来的组合默认值变化。
+
+**暴露所有 Settings 注册，或增加通用的 `local-client` 声明。** 本次变更不予采纳，因为这会扩大安全边界，并使 Settings 契约超出所请求的单项偏好。显式加入 `permission` allowlist 已足够，未来的 namespace 可以各自决定是否暴露。
+
+**恢复带 seed 的会话时应用最新默认值。** 不予采纳，因为恢复操作必须保留会话先前的有效执行策略；缺失的旧版事实应从该策略中补齐。

+# Agent Note: Session archive (registry-global set)
+
+Status: implemented
+
+English | [中文](2026-07-31-session-archive-global-set.zh.md)
+
+## Problem
+
+The session row menu in the sidebar workspace browser carried a purely visual "Delete session" placeholder (no handler). The product decision is **archive**, not delete: the session log and its workspace accounting stay untouched; the session merely disappears from every grouping surface (workspace groups, Ungrouped, search, the flat list). The archive record needs a home: an Ungrouped session belongs to no workspace entity, so a per-workspace field cannot carry it.
+
+## Decision
+
+**The archive set is a new field on the workspace domain's global singleton (`workspaceDomainState.archivedSessionIds`), layered over workspace accounting; display filtering converges entirely in the client's `tree.ts` derivation layer; the wire surface uses the full-snapshot posture.**
+
+- Storage: `archivedSessionIds: z.array(sessionId).default([])`, domain version stays 2 — a purely additive field; pre-field media parse to an empty set through the schema default, no migration code. An archived session keeps its `sessionIds` slot (a future unarchive restores its position), so the set never touches the one-owner accounting invariant.
+- Registry: `ctx.workspace.archiveSession(id)` rides `enqueueOperation`, serialized with create/delete; a session neither live nor persisted throws `WorkspaceUnknownSessionError`; an already archived id neither writes nor emits. The `archivedSessionIds` getter exposes the read-only set.
+- RPC: `workspace.archiveSession({sessionId}) → {archivedSessionIds}` (answers the full updated set); the `workspace.list` response carries the set as the reconnect baseline; a new host frame `host/archived-sessions-changed` pushes the full snapshot after every durable change (same posture as `host/workspace-changed`, emitted from the `domain/changed` global-put branch by set comparison). Unknown sessions reuse the `session-not-found` error code.
+- Client runtime: `WorkspaceListState.archivedSessionIds` (a `readonly SessionId[]` in Host order, reference replaced only on membership change — public snapshot state stays in the store engine's plain-data vocabulary since immer drafts reject Sets without the MapSet plugin; membership lookups build a transient Set in the derivation, the expandedProjects pattern); the list baseline, the unary echo, and the changed frame each install the complete set. the projection sweep clears the current selection whenever it lands in the archive set, returning to the New Session view (user decision: archiving the open session sends the main view back to the hero) — one rule covering the local unary echo, another tab's changed frame, and a reconnect baseline restoring a selection archived while this client was away; a frame or echo landing during an in-flight `workspace.list` also shields the newer set from the stale baseline.
+- UI: the `delete` menu row (visual-only) becomes `archive` (label "Archive session", non-danger styling, no confirmation dialog — a non-destructive action whose worst misfire is list hiding); filtering is one extra arm in `tree.ts`'s `sessionVisible` predicate, with `deriveGroups`/`deriveFlat` taking an `archived` set parameter so all four surfaces (group loop, stray bucket, search, flat) share one source.
+
+## Alternatives considered
+
+**Per-workspace archivedSessionIds (the original phrasing).** Rejected: Ungrouped sessions have no home; the user switched to global.
+
+**An archived flag on SessionSummary (session.list layer).** Rejected: it joins a workspace-domain fact into the sessions-domain projection, summaries have no incremental frame so a separate notification would still be needed — cross-domain coupling outweighs the saving.
+
+**Host-side filtering in `workspaceView`/the `sessionIds` getter.** Rejected: archiving ≠ changing accounting, and filtering the projection muddles the two concepts; a future restore surface also needs the client to see full accounting.
+
+**Incremental frames (single archived/removed rows).** Rejected: the set is tiny and changes rarely; full snapshots spare the client merge logic and dedup state and match the existing workspace-changed posture.
+
+## Consequences
+
+Archived sessions have no viewing or unarchive surface yet (this iteration's scope; recorded as a README Known Limitation); data and accounting slots stay intact, so a future restore is one UI surface plus one inverse RPC. The `workspace.list` response shape change is a pre-release direct edit (no compatibility layer). The workspace-management e2e pins the full chain (archive → row disappears → still hidden after reload, log still present); domain tests pin idempotence, unknown-id rejection, restart recovery, and the pre-field media default upgrade.

+# Agent Note: Session 归档（注册表级全局集合）
+
+状态：implemented
+
+[English](2026-07-31-session-archive-global-set.md) | 中文
+
+## 问题
+
+Sidebar workspace 浏览区的 session 行菜单里，「Delete session」一直是纯视觉占位（无 handler）。产品口径定为**归档**而非删除：session 日志与 workspace 记账都不动，只把该 session 从所有分组视图（workspace 分组、Ungrouped、搜索、平铺列表）里隐藏。归档记录需要一个落点：Ungrouped 的 session 不属于任何 workspace 实体，per-workspace 字段放不下它。
+
+## 决策
+
+**归档集合是 workspace domain 全局单例（`workspaceDomainState.archivedSessionIds`）上的一个新字段，覆盖在 workspace 记账之上；显示过滤全部收敛在 client 的 `tree.ts` 派生层；wire 面走全快照姿态。**
+
+- 存储：`archivedSessionIds: z.array(sessionId).default([])`，domain version 保持 2——纯增量字段，旧介质经 schema default 解析为空集合，无迁移代码。被归档的 session 保留其 `sessionIds` 席位（未来取消归档恢复原位置），因此与「一个 session 只被一个 workspace 记账」不变式零纠缠。
+- Registry：`ctx.workspace.archiveSession(id)` 走 `enqueueOperation` 与 create/delete 串行；未知 session（实时与持久化都查不到）抛 `WorkspaceUnknownSessionError`；已归档 id 不写盘不发事件。`archivedSessionIds` getter 暴露只读集合。
+- RPC：`workspace.archiveSession({sessionId}) → {archivedSessionIds}`（应答完整更新后集合）；`workspace.list` 响应携带集合作为重连基线；新 host 帧 `host/archived-sessions-changed` 在每次持久变更后推完整快照（与 `host/workspace-changed` 同姿态，从 `domain/changed` 的 global put 分支比对推帧）。未知 session 复用错误码 `session-not-found`。
+- client runtime：`WorkspaceListState.archivedSessionIds`（按 Host 顺序的 `readonly SessionId[]`，成员不变不换引用——公有快照状态保持 store 引擎的纯数据词汇：immer draft 不开 MapSet 插件就不接受 Set；membership 查询在派生函数内自建临时 Set，与 expandedProjects 同款）；list 基线、unary 回声、changed 帧三路都整体替换安装。投影层在当前 selection 落入归档集合时统一清空回 New Session 视图（用户拍板：归档当前打开的 session 主视图回 hero）——一条规则同时覆盖本地 unary 回声、其他标签页的 changed 帧、以及重连基线恢复出一个离线期间被归档的 selection；帧/回声落在 in-flight `workspace.list` 期间时还会屏蔽旧基线对新集合的回滚。
+- UI：菜单项 `delete`（visual-only）改为 `archive`（label「Archive session」，非 danger 样式，无确认对话框——非破坏性操作，误触后果只是列表隐藏）；过滤实现为 `tree.ts` 的 `sessionVisible` 判据加一档，`deriveGroups`/`deriveFlat` 增加 `archived` 集合入参，四个视图（分组循环、stray 兜底、搜索、平铺）同源生效。
+
+## 已考虑的替代方案
+
+**per-workspace archivedSessionIds（最初表述）。** 否决：Ungrouped session 无落点；用户改口全局。
+
+**SessionSummary 打 archived 标（session.list 层）。** 否决：要把 workspace domain 事实 join 进 sessions domain 投影，summary 无增量帧还得另发通知，跨域耦合大于收益。
+
+**host 侧在 `workspaceView`/`sessionIds` getter 过滤。** 否决：归档 ≠ 改记账，投影过滤会把两个概念搅浑；未来恢复入口也需要 client 拿到全量记账。
+
+**增量帧（archived/removed 单条）。** 否决：集合极小、变更频率低，全快照免去 client 侧合并逻辑与去重状态，与 workspace-changed 现有姿态一致。
+
+## 后果
+
+归档后 UI 无查看/取消归档入口（本期口径，README Known Limitation 记账）；数据与席位完好，后续加恢复面只是 UI + 一个逆向 RPC。`workspace.list` 响应形状变化是 pre-release 直改（无兼容层）。e2e（workspace-management）钉住了「归档→行消失→reload 后仍隐藏、日志仍在」的全链路；domain 层测试钉住幂等、未知 id 拒绝、跨重启恢复与旧介质默认升级。

 A seeded session — resume, fork, or replay — appends this log-only event immediately after its constructor seed, as its first live write. Events before it have smaller seq values and came from the seed. It is the durable projection of `firstLiveSeq`: that field answers where this lifecycle's writes start for a consumer holding the object, while the event answers the same question for one holding only stored bytes. The payload is empty, so position and `time` carry the whole meaning, and it produces no message. `Session`'s constructor is the only legitimate writer.
 
-An empty seed writes nothing, and a seed already ending in `session/end-seed` is not re-marked, so reopening an untouched session does not grow its log per pickup. Locate the LAST `session/end-seed` in stored history rather than assuming one exists at `firstLiveSeq`: after a pickup with no work, the event has a smaller seq than the next lifecycle's `firstLiveSeq`.
+An explicitly supplied empty seed writes `session/end-seed` at seq 0, which distinguishes an empty resumed session from a fresh one. A seed already ending in `session/end-seed` is not re-marked, so reopening an untouched session does not grow its log per pickup. Locate the LAST `session/end-seed` in stored history rather than assuming one exists at `firstLiveSeq`: after a pickup with no work, the event has a smaller seq than the next lifecycle's `firstLiveSeq`.
 
 It exists because seed history and live work are otherwise byte-identical, which defeats any plugin owning a standalone open/close bracket: an unmatched `compact/start` reads the same whether the writer crashed mid-compaction or is compacting right now. An opening marker before `session/end-seed` came from the constructor seed and belongs to an ended lifecycle, whatever ended it (a crash, a succeeding process, or a fork out of a still-running parent), so its owner may treat it as dead. That covers only brackets *this* session inherited: a concurrently live session holding an open bracket over the same history has its own boundary elsewhere, so tolerating concurrent writers needs a liveness signal beyond the log. Core writes the boundary and reads nothing from it — a bracket's vocabulary stays with its owning plugin, which is why crash repair closes turn/step/tool boundaries and never `compact/*`.

 `WorkspacesService.delete(workspaceId)` removes the registration from the client projection after the successful unary response; the matching `host/workspace-removed` frame is idempotent and synchronizes other tabs. Session state and the current Session selection are independent, so accounted Sessions immediately project under Ungrouped after their Workspace disappears.
 
+`WorkspaceListState.archivedSessionIds` mirrors the Host's registry-global archive set (a `readonly SessionId[]` in Host order, replaced only when membership changes; consumers needing O(1) lookups build a transient Set). It is full-snapshot state: the `workspace.list` baseline, the `archiveSession` unary echo, and the `host/archived-sessions-changed` frame each install the complete set. `WorkspacesService.archiveSession(sessionId)` archives over the wire; the projection sweep clears the current selection into the New Session view state whenever it lands in the archive set — one rule covering the local echo, another tab's frame, and a reconnect baseline restoring a selection archived while this client was away. A set installed while a `workspace.list` request is in flight also supersedes that stale baseline's set. Grouping surfaces hide members everywhere while the session rows stay in the list store.
+
 SlotsService gives the renderer separate bare observables for `useSessions` and `useWorkspaces`; web-react creates the hooks. Workspace business state does not enter `SessionListState` or an entry store.
 
 `SessionsService.search(query, signal)` is a stateless one-shot action over the `session.search` RPC. It returns ranked session/snippet pairs without putting query, loading, or error state into the shared Session list, so each UI owner controls debounce, cancellation, stale-response suppression, and fallback presentation. `searchResultLimit` re-exposes `SESSION_SEARCH_RESULT_LIMIT` — the bound the response schema itself enforces — as injected presentation data, so client plugins do not duplicate it. It is a protocol constant rather than per-connection state, so the connection handle does not carry it.

 `WorkspacesService.delete(workspaceId)` 在一元响应成功后从客户端投影中移除注册记录；对应的 `host/workspace-removed` 帧具有幂等性，并负责同步其他标签页。Session 状态与当前 Session selection 相互独立，因此 Workspace 消失后，其已纳入客户端投影的 Session 会立即投影到 Ungrouped 下。
 
+`WorkspaceListState.archivedSessionIds` 镜像 Host 的注册表级全局归档集合（一个按 Host 顺序的 `readonly SessionId[]`，仅在成员变化时才替换；需要 O(1) 查询的消费方自建临时 Set）。它是全快照状态：`workspace.list` 基线、`archiveSession` 一元回声和 `host/archived-sessions-changed` 帧各自安装完整集合。`WorkspacesService.archiveSession(sessionId)` 通过 wire 归档；投影层在当前 selection 落入归档集合时统一清空为 New Session 视图状态——一条规则同时覆盖本地回声、其他标签页的帧、以及重连基线恢复出一个离线期间被归档的 selection。在 `workspace.list` 请求进行中安装的集合还会取代该过期基线携带的集合。各分组视图在所有位置隐藏集合成员，而会话行本身仍留在列表 store 中。
+
 SlotsService 分别为 renderer 提供 `useSessions` 与 `useWorkspaces` 的裸 observable；web-react 创建钩子。Workspace 业务状态不会进入 `SessionListState` 或配置项 store。
 
 `SessionsService.search(query, signal)` 是基于 `session.search` RPC 的无状态单次操作。它返回经过排序的会话／snippet 对，但不会将查询条件、加载状态或错误状态写入共享 Session 列表，因此每个 UI 所有者都自行负责防抖、取消、抑制陈旧响应和回退呈现。`searchResultLimit` 将 `SESSION_SEARCH_RESULT_LIMIT`——即响应 schema 自身强制执行的上限——作为注入的呈现数据重新公开，使客户端插件无需复制该值。它是协议常量而非逐连接状态，因此连接 handle 不携带它。

-Models settings plugin: the provider configuration page and official-DeepSeek conditional onboarding step. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
+Models settings plugin: the provider configuration page and official-DeepSeek conditional onboarding step. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time, without presenting route liveness as provider status.
 
-Rows are the *configured* providers (their profile resolves in the owning namespace); a whole-section provider whose key is not configured anywhere (the first-run DeepSeek posture) renders as its open setup card instead of a row, and the add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor is a hand-written card per adapter family: the primary field is a single **API key** input — the page never asks for an environment-variable name; a typed key stores **write-only** through `credentials.set` under the profile's reference, deriving `<ROUTE>_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. The collapsed 自定义设置 fold carries the curated extras — `baseURL` for both families (the deepseek placeholder shows the public endpoint), plus `reasoningEffort` (deepseek) or `reasoning` (pi-ai); every other profile field stays owned by `settings.yaml`. A row is deletable only when the user layer alone carries it (removal restores the composition base).

A row is deletable only when the user layer alone carries it (removal restores the composition base), and a localized confirmation dialog must complete before the page submits that destructive unset.
 
 The DeepSeek step projects `deepseek-official` readiness from that same joined snapshot after earlier onboarding pages complete. It recognizes the official adapter through its `llm-deepseek` configurable-provider declaration, so an undeclared live route with the same provider id is not treated as repairable configuration. A configured literal `apiKey` secret sidecar or configured credential reference completes the step without rendering, including a read-only launch-environment credential. Only a mounted, active adapter with a missing writable reference shows the page that opens Settings on Models, whose existing setup card exclusively owns key input and `credentials.set`; the step never holds a secret. An absent adapter, inactive route, failed join, read-only deployment, or unusable settings or credential capability completes the step without rendering so onboarding cannot block the product; Models remains the diagnostic surface.

-模型设置插件：提供方配置页和按条件显示的 DeepSeek 官方首次使用引导步骤。它把三个协议领域汇聚为一个共享快照：`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）；页面据此渲染提供方行，一次只展开一张编辑卡片。

-行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；密钥未在任何地方配置的整分节提供方（DeepSeek 的首次运行姿态）会渲染为其展开的设置卡片而非一行，「新增」流程则是一张承载休眠目录提供方选择框的卡片——裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器是每个适配器家族各一张的手写卡片：主字段是单独一个 **API 密钥**输入框——页面从不询问环境变量名；键入的密钥经 `credentials.set` 以**只写**方式存入 profile 的引用之下，profile 没有引用时便派生 `<ROUTE>_API_KEY`，pi-ai profile 会把这次派生记录为 `apiKeyEnv`，因此 `settings.yaml` 从不携带密钥值。收起的「自定义设置」折叠区承载精选的额外字段——两个家族都有 `baseURL`（deepseek 的占位符显示公共端点），另加 `reasoningEffort`（deepseek）或 `reasoning`（pi-ai）；其余每个 profile 字段仍归 `settings.yaml` 所有。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。

 前序首次使用引导页面完成后，DeepSeek 步骤会从同一个联接快照得出 `deepseek-official` 的就绪状态。它通过 `llm-deepseek` 的可配置提供方声明识别官方适配器，因此同 id 但未声明的存活路由不属于可修复配置。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，该步骤会直接完成而不渲染，其中包括来自启动环境且只读的凭据。只有已挂载且活跃、引用可写但尚未配置的适配器才会显示前往「设置」Models 分区的页面；密钥输入和 `credentials.set` 仅由该分区已有的设置卡片负责，该步骤绝不持有 secret。适配器缺失、路由不活跃、联接失败、部署只读或设置／凭据能力不可用时，该步骤均不渲染并直接完成，以免首次使用引导阻塞产品；Models 页仍是诊断界面。

-Permission preset selection plugin, browser half: a popupSelect DECORATION hung on the host `/permission` command (`ctx.command.decorate`). A decoration is not a second command — the host command keeps its slash-menu row, the argued path (`/permission <preset>` switches directly), and the durable lifecycle logging; the decoration replaces only the bare invocation with the picker: one flat preset list with the current value marked active and kebab-case preset names rendered as title-case labels (`workspace-write` → `Workspace Write`, the composer chip's display transform twin), where a pick submits the `/permission <preset>` command line. Options and the active mark read the session's `permissions` projection (the same host-computed select the composer chip renders), so both surfaces share one read source and one write path, and the pushed projection frame is the single confirmation both follow. The decoration is available exactly while the projection key is present; a permission-less composition shows no picker (a decoration never manufactures a catalog row).
+Permission browser surfaces for two different lifetimes. The General-settings row reads the explicitly exposed `permission` Settings descriptor, derives its options from the host's dynamic `defaultPreset` enum, and writes one `settings.mutate` path operation with the descriptor revision. Its observable rides the slot system's `hooks` compartment, so the renderer owns React hook binding; a push invalidation refetches the descriptor. This value applies only when a later session is created; changing it does not switch the current session. Choosing Full access requires an explicit risk acknowledgement before the row writes it.

 `src/onboarding-copy.ts` is the single editable owner of the complete Chinese and English notice plus `WELCOME_NOTICE_VERSION`. The Host half registers `ui-onboarding` in the user-settings seam; the browser compares `welcomeNoticeVersion` for exact equality and writes the current value only after Continue succeeds. The path mutation is idempotent across tabs and preserves sibling settings, while `host/settings-changed` makes an externally acknowledged notice advance without a reload. A different version deliberately presents the notice again. The welcome page preserves every authored paragraph, gives the requested clause in the final paragraph the sole emphasis, initially focuses the title, and has no close, Escape, mask-click, or secondary path. None of its copy or acknowledgement enters a Session log or model request.
