+# Agent Note: Semantic Issue templates and presentation-neutral policy
+
+Status: implemented
+
+English | [中文](2026-09-03-semantic-issue-templates-and-policy.zh.md)
+
+## Problem
+
+Issue and pull-request templates mixed intake questions with review evidence and hid their complete contents in `details` elements. Unused frontmatter and separate Idea and Research templates added choices without changing how the repository planned the work.
+
+Issue policy also treated Markdown presentation as repository metadata. Requirements for `details` elements, a 50-unit visible body, Chinese titles, title metadata prefixes, and an `Owner:` body line produced failures without identifying a missing semantic decision.
+
+## Decision
+
+Issue templates cover Bug, Feature, and Task. Bug asks for a summary, reproduction, current behavior, expected behavior, and environment. Feature asks for motivation and behavior. Task asks for a summary and deliverables. Idea and Research belong in Task unless a future decision gives them distinct lifecycle behavior.
+
+Issue-template frontmatter contains only `name`, `about`, and `type`. Markdown headings define the hierarchy, and HTML comments explain what belongs under each heading.
+
+The pull-request template contains `Motivation`; a `Changes` section with adjacent placeholders for public-interface and behavior changes; and `Testing` entries that show each method directly and place its proof in a local `details` element.
+
+Issue policy does not inspect `details` presentation, visible-body length, title language, title prefixes, or body ownership lines. Every other policy check, warning, lifecycle operation, workflow trigger, and pull-request enforcement exemption retains its existing behavior. This decision adds no metadata repair, Issue classification, data migration, or workflow capability.
+
+## Verification
+
+[Issue-management tests](../../../../.github/issue-management/policy.test.mjs) pin the template inventory and headings, the pull-request testing structure, and acceptance of titles, bodies, and assignee states that differ only in presentation.
+
+## Alternatives considered
+
+**Keep Idea and Research templates.** Their forms did not establish lifecycle or policy behavior distinct from Task, so separate entry points increased choice without preserving a meaningful type distinction.
+
+**Keep presentation rules as warnings.** These rules could fail otherwise actionable Issues and could not establish whether the requested work, expected behavior, or deliverables were clear.
+
+**Add automatic metadata repair or Issue classification.** Those behaviors require new mutation rules, permissions, failure handling, and operational evidence. They remain separate decisions rather than accompanying a policy simplification.
+
+## Consequences
+
+Contributors see shorter forms whose headings match the information needed at Issue intake and pull-request review. Policy failures remain focused on the existing semantic metadata checks.
+
+The policy does not rewrite legacy labels, choose missing Issue Types, synchronize Priority, or migrate existing repository data. Any future automation for those operations needs its own decision and review scope.

+# Agent Note: 语义化 Issue template 与不检查展示形式的 policy
+
+Status: implemented
+
+[English](2026-09-03-semantic-issue-templates-and-policy.md) | 中文
+
+## 问题
+
+Issue 与拉取请求（Pull Request，PR）template 把信息收集问题与评审证据混在一起，并用 `details` 元素折叠全部内容。未使用的 frontmatter 以及独立的 Idea 和 Research template 增加了选择，却没有改变仓库规划这些工作的方式。
+
+Issue policy 还把 Markdown 展示方式当成仓库 metadata。对 `details` 元素、50 单位可见正文、中文标题、标题 metadata 前缀和正文 `Owner:` 行的要求会产生失败，却不能指出缺少了哪项语义决策。
+
+## 决策
+
+Issue template 只覆盖 Bug、Feature 和 Task。Bug 收集摘要、复现方式、当前行为、预期行为和环境。Feature 收集动机和行为。Task 收集摘要和交付物。除非未来的决策为 Idea 与 Research 定义不同的生命周期行为，否则它们属于 Task。
+
+Issue template frontmatter 只含 `name`、`about` 和 `type`。Markdown 标题定义信息层级，HTML 注释说明每个标题下应填写的内容。
+
+PR template 包含 `Motivation`、在 `Changes` 中相邻排列的公共接口与行为变化占位说明，以及直接展示每项测试方法并在局部 `details` 元素中放置对应证明的 `Testing` 条目。
+
+Issue policy 不检查 `details` 展示形式、可见正文长度、标题语言、标题前缀或正文 ownership 行。其他所有 policy 检查、警告、生命周期操作、workflow 触发条件和 PR 强制范围豁免均保持既有行为。这项决策不增加 metadata 自动修复、Issue 分类、数据迁移或 workflow 能力。
+
+## 验证
+
+[Issue 管理测试](../../../../.github/issue-management/policy.test.mjs)固定 template 清单与标题、PR 测试结构，并验证仅展示形式不同的标题、正文和 assignee 状态可以通过。
+
+## 考虑过的替代方案
+
+**保留 Idea 和 Research template。** 它们的表单没有建立区别于 Task 的生命周期或 policy 行为，因此独立入口只会增加选择，而不能保留有意义的 Type 区别。
+
+**把展示规则保留为警告。** 这些规则会让原本可执行的 Issue 失败，也不能确定需求工作、预期行为或交付物是否清晰。
+
+**增加 metadata 自动修复或 Issue 分类。** 这些行为需要新的修改规则、权限、失败处理和运行证据。它们应作为独立决策，而不随 policy 简化一同引入。
+
+## 后果
+
+贡献者会看到更短的表单，其标题分别对应 Issue 信息收集和 PR 评审所需的信息。Policy 失败会继续聚焦现有的语义 metadata 检查。
+
+Policy 不会改写旧标签、选择缺失的 Issue Type、同步 Priority 或迁移现有仓库数据。这些操作未来如需自动化，必须单独决策和评审。

Subject: [PATCH 02/70] docs(notes): normalize Chinese Agent Note header tokens
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Agent Note rules keep the `# Agent Note: ` title prefix and the
`Status:` line in English verbatim on both language sides. 51 Chinese
counterparts carried a full-width colon (`# Agent Note：`), an annotated
prefix (`# Agent Note（agent 决策记录）：`), or a translated status token
(`状态：已实现`, `状态：implemented`, `状态：已实施`, `状态：proposed`), which the
archive verifier rejects on entry to the frozen tree. Normalize the tokens
and re-record the bilingual sidecars; no body text changes.

From 452b2a816a58151b48d6db7c8ce9c6ec761d988f Mon Sep 17 00:00:00 2001
From: Yichen Jiang <jyc132780208@sina.com>

Subject: [PATCH 03/70] refactor(client): share the capsule tag, switch, and
 idle state dot

Client feature plugins never import one another's components, so
ui-primitives is their only channel for sharing one. Nothing told an
author to look there first, and the package offered nothing to look
at: its README named six source files against forty-plus exports.

Add Tag (read-only capsule badge, eight tones) and Switch (36x20
toggle with a required accessible name), extend StateDotState with
idle for a tracked subject with no activity, and move ui-agent-preset,
ui-settings-plugins, and ui-settings-plugin-inventory onto them.

The plugin inventory's conditional tag referenced
--dsw-alias-state-warning-primary, which does not exist, so both
themes had been painting its hardcoded #b45309 fallback.

State the reuse rule as the first step of the new-component checklist,
and give the README a component catalog so the rule has something to
check. The rule is guidance, not a gate: a package may still write its
own control, and the Agent Note records the five that stay local.

+# Agent Note: Shared client control primitives
+
+Status: implemented
+

+
+## Problem
+
+Client feature plugins compose through slots and never import one another's values, so `@deepseek-ai/dsh-client-ui-primitives` is their only channel for sharing a React component. A control that grows inside one feature package is invisible to the next package that needs the same thing, and copying its markup and CSS is the cheapest move available. Three families had diverged that way. A 36×20 toggle switch existed only inside `ui-settings-plugins`. Read-only capsule badges were declared five separate times across `ui-agent-preset`, `ui-settings-plugins`, and `ui-settings-plugin-inventory`, with two different corner radii and separately authored palettes. A plugin-phase status dot was reimplemented in `ui-settings-plugin-inventory` next to the shared `StateDot` it duplicates.
+
+Neither half of the fix was available to an author. No checklist told them to look in `ui-primitives` before writing a control, and the package gave them nothing to look at: its README named six source files while the package exported more than forty symbols.
+
+## Decision
+
+**A control that a second client package needs lives in `ui-primitives`.** The rule is guidance for authors, not a gate: a feature package may still write its own component when its need is genuinely specific, and the [what stays local](#what-stays-local) list below records the cases from this change. What the rule forbids is the copy — when a control already exists, the author either uses it or lifts the deliberate difference into a prop.
+
+`Tag` is the read-only capsule badge. Its geometry is fixed at the size `ui-agent-preset` established: `999px` radius, `1px 8px` padding, 11px text on a 17px line, 500 weight, `inline-flex`, no wrapping. A single closed `TagTone` union selects the palette, and every member exists because a shipped call site needed it: `outline` and `solid` from the agent-preset section, `neutral` and `quiet` from the plugin settings fields, and `success`, `info`, `warning`, and `danger` from the plugin inventory's enablement tags. The component carries no copy of its own, as every Cordis-free primitive must.
+
+`Switch` is the two-state toggle, at the 36×20 track and 16px thumb `ui-settings-plugins` established. `label` is required and has no default, so a render site cannot omit the accessible name; `title` carries a lock reason where a deployment disables the control.
+
+`StateDotState` gains `idle`, a static grey dot in the same halo-and-core construction as `done`, `warning`, and `error`. The plugin inventory's `pending` and `unloading` phases mean no activity is in progress, and the four existing states had no member for that; without `idle` those two phases lose their marker entirely. The addition is safe for the eight packages already consuming `StateDot` because each of them produces a `StateDotState` from its own closed status union and none switches over `StateDotState` itself.
+
+**The component catalog in the `ui-primitives` README is what makes the rule usable.** It lists every exported component with its purpose and the case it is wrong for, and it names the three pairs that are easy to confuse: `Tag` against `Pill`, `DisclosureRow` against card-shaped disclosure, and the package-internal `FoldToggle` against the exported surface. `Pill` is the selectable capsule button — it takes `active` and `onClick` and drives view switchers and filters; `Tag` is the read-only badge and takes neither. `Pill`'s own header comment previously advertised itself for badges, which contradicted the catalog, and no longer does.
+
+The rule is stated in [packages/client/AGENTS.md](../../../../packages/client/AGENTS.md) as the first step of the new-component checklist, and [docs/web-styling.md](../../../../docs/web-styling.md) points at the catalog so an author arriving from the styling side reaches it too.
+
+## Finding the duplicates
+
+A name-based search undercounts. `.badge`, `.tag`, `.chip`, and `.configTag` miss a capsule named for its role rather than its appearance — `PluginCard`'s unsaved marker is `.pending`, and its rule was byte-identical to the badge two files away. What finds them is the geometry: a CSS Modules rule carrying both `border-radius: 999px` and `padding: 1px 8px`. After this change that signature matches exactly three rules — `Tag` itself, the broken badge below, and the `flex: none` placement class the unsaved marker kept.
+
+<a id="what-stays-local"></a>
+## What stays local
+
+A mechanical search groups these controls with the promoted three. They stay in their own packages, because the grouping is superficial:
+
+- **`ui-trajectory`'s toolbar toggle** carries `role="switch"` but is an 88px labelled control with an inline track, and it currently renders `hidden`. It is not the same widget as `Switch`.
+- **`ui-schedule`'s status dot** is a static blue dot for the next run that turns amber when overdue. `StateDot` has no static blue — its only blue is `ongoing`, an animated pixel matrix — and one animation per row in a schedule list would misstate the meaning as well as the appearance.
+- **`ui-plan`'s mode chip** and **`ui-conversation`'s `ReferenceChip`** are interactive: the first is a warning-toned button with hover, focus, disabled, and a close affordance; the second is a Lexical atom node with its own truncation. Neither is a read-only badge.
+- **`ui-trajectory`'s cell tag** and **`ui-user-questions`'s recommendation badge** use their own geometry — a 6px radius at table density, and a 6px radius at 600 weight on the sidebar accent. Forcing either into the capsule baseline would change a deliberate design, not an accidental one.
+- **`ui-agent-preset`'s broken badge** shares the capsule geometry but carries a solid error fill that no second site uses, and it is the hover anchor for a tooltip element of its own. `Tag` would have to keep a palette override in the feature stylesheet and depend on cross-file CSS ordering to win it.
+
+## Alternatives considered
+
+**A `SettingsCard` primitive.** Rejected. `.card` appears in fifteen packages, but only three carry settings-page semantics, and those three differ in behaviour rather than appearance: `ui-settings-plugins`' `PluginCard` stages edits and collapses only after a Host-confirmed save, `ui-agent-preset`'s cards are selectable, and the plugin inventory's are read-only. `PluginCard`'s own header comment already records why it cannot use the shared disclosure row. A single component would have to accept all three behaviours through props that no caller uses more than one of.
+
+**A gate rejecting `role="switch"` or a `.switch` rule outside `ui-primitives`.** Rejected. The goal is that authors reuse what exists, not that they are prevented from building. A gate would fail a package with a legitimately specific control — `ui-trajectory`'s labelled toolbar toggle is exactly that case — and the cost of the false rejection lands on the author least able to argue with it. The catalog plus the checklist step address the actual failure, which is that authors did not know the control existed.
+
+**Preserving every current appearance behind extra `Tag` props.** Rejected. The plugin inventory's 5px radius and the agent-preset capsule are the same kind of tag in two shapes, and neither difference was decided. Keeping both would fix an accident into a public union and leave the next author to guess which one to pick.
+
+**Extending `Pill` instead of adding `Tag`.** Rejected. `Pill` is 24px tall on a 12px radius with 12px text; the badge baseline is denser and rounder. Merging them would produce one component whose size depends on whether `onClick` is present, and would erase the read-only/selectable distinction that the catalog needs in order to answer "which one do I want".
+
+**A two-axis `variant × tone` API for `Tag`.** Rejected. Three variants against six tones describes eighteen combinations of which six ship, and it lets a caller request combinations with no defined appearance. The flat eight-member union maps each value to exactly one shipped appearance.
+
+**Rendering no dot for `pending` and `unloading` instead of adding `idle`.** Rejected. Those rows show a grey dot today, and dropping it would remove information from the inventory in a change whose purpose is to consolidate presentation.
+
+**Putting the reuse rule in the root `AGENTS.md`.** Rejected. The rule governs `packages/client` alone, and the root file sits exactly at its 1950-word ceiling in `scripts/doc-budgets.manifest.json`, so stating it there would have to displace an unrelated repository-wide rule.
+
+## Testing
+
+`Tag`, `Switch`, and the extended `StateDot` carry component specs in `packages/client/ui-primitives/tests`, inside the per-file 100% coverage gate. `StateDot`'s palette is pinned by reading its stylesheet: CSS Modules resolve to class-name maps in the component suites, so a state whose color rule is missing renders on the inherited color and no render assertion notices.
+
+The four migrated render sites keep their existing package specs unchanged. The web e2e goldens are ARIA snapshots, and the full replayed web suite passes without re-recording, because the migration preserves every role, accessible name, and state — `Switch` keeps `role="switch"` with `aria-checked`, and the inventory's phase dot keeps its `role="img"` name on a wrapper, since `StateDot` is `aria-hidden`.
+
+That is also the limit of the automated evidence. No gate in this repository compares pixels, so the capsule geometry, the dot halo, and the font-weight change are verified by review against the light and dark screenshots in the pull request.
+
+## Consequences
+
+- A new client control now has one place to check and one place to add, and the catalog makes the check a single file read rather than a `grep` over forty exports.
+- `TagTone` is eight members wide because eight appearances shipped. Adding a ninth requires a render site that needs it, not a symmetry argument.
+- The plugin inventory's tags change from a 5px rectangle to a capsule and its phase dots gain a halo and, in the loading phase, an animation. The unconfigured-secret badge in the plugin settings fields moves from 400 to the baseline 500 weight. These are deliberate visual changes, recorded here so a later reader does not treat them as regressions.
+- The migration removes a literal `#b45309`. The plugin inventory's `conditional` tag read `var(--dsw-alias-state-warning-primary, #b45309)`, and no such alias exists — the real token is `--dsw-alias-state-warn-primary` — so both themes had been painting the hardcoded fallback that [docs/web-styling.md](../../../../docs/web-styling.md) forbids.
+- The rule cannot be checked mechanically. A future author can still copy a control, and only review will catch it. That is the accepted cost of not gating: the alternative rejects legitimate work, and the packages that stay local above are proof that legitimate work exists.
+- `ui-primitives` grows two components that one package each consumes today. The switch in particular is a single-consumer primitive, promoted because it is a general control and because the plugin-management work already in flight will adopt it rather than adding two further copies.

+# Agent Note: Shared client control primitives
+
+Status: implemented

+
+## Problem
+
+客户端功能插件通过 slot 组合，彼此从不 import 对方的值，因此 `@deepseek-ai/dsh-client-ui-primitives` 是它们共享 React 组件的唯一通道。在某个功能包内部长出来的控件，对下一个需要同样东西的包不可见，而复制它的标记与 CSS 是当时最省事的做法。三类控件已经这样分叉：36×20 的开关只存在于 `ui-settings-plugins`；只读胶囊徽章在 `ui-agent-preset`、`ui-settings-plugins`、`ui-settings-plugin-inventory` 里被分别声明了五次，带着两种圆角和各自编写的配色；插件相位状态点在 `ui-settings-plugin-inventory` 里被重新实现，就在它所复制的共享 `StateDot` 旁边。
+
+修复所需的两半，作者当时一半也拿不到。没有任何清单要求他们在写控件前先看 `ui-primitives`，而这个包也没给他们可看的东西：README 只列了六个源文件，包却导出了四十多个符号。
+
+## Decision
+
+**第二个客户端包需要的控件，住在 `ui-primitives`。** 这条规则是对作者的引导，不是门禁：功能包在需求确实特殊时仍可以自己写组件，下面的[保留在原包的控件](#what-stays-local)记录了本次改动中的这些例子。规则禁止的是复制——控件已经存在时，作者要么用它，要么把那处有意的差异提升成一个 prop。
+
+`Tag` 是只读胶囊徽章。几何锁定在 `ui-agent-preset` 确立的尺寸：`999px` 圆角、`1px 8px` 内边距、11px 字号配 17px 行高、500 字重、`inline-flex`、不换行。单个闭合的 `TagTone` 联合选择配色，每个成员都因为有已发布的调用点需要它而存在：`outline` 与 `solid` 来自 agent preset 区块，`neutral` 与 `quiet` 来自插件设置字段，`success`、`info`、`warning`、`danger` 来自插件清单的启用标签。与所有 Cordis-free 原语一样，这个组件不自带任何文案。
+
+`Switch` 是双态开关，采用 `ui-settings-plugins` 确立的 36×20 轨道与 16px 滑块。`label` 必填且没有默认值，渲染点无法省略无障碍名称；`title` 在部署禁用该控件时承载锁定原因。
+
+`StateDotState` 增加 `idle`，一个静态灰点，与 `done`、`warning`、`error` 采用同样的光晕加实心核结构。插件清单的 `pending` 与 `unloading` 相位表示没有进行中的活动，原有四态没有对应成员；没有 `idle`，这两个相位会彻底失去标记。这次增补对已经消费 `StateDot` 的八个包是安全的：它们各自从自己的闭合状态联合**产生** `StateDotState`，没有任何一个对 `StateDotState` 本身做 switch。
+
+**`ui-primitives` README 里的组件目录，是这条规则得以可用的前提。** 它列出每个导出组件的用途，以及它不适用的场合，并点名三组容易混淆的配对：`Tag` 与 `Pill`、`DisclosureRow` 与卡片式折叠、包内的 `FoldToggle` 与对外导出面。`Pill` 是可选中的胶囊按钮——它接受 `active` 与 `onClick`，用于视图切换与筛选器；`Tag` 是只读徽章，两者都不接受。`Pill` 自己的头注释此前把自身宣传为可用作徽章，与目录互相矛盾，现已改掉。
+
+规则写在 [packages/client/AGENTS.md](../../../../packages/client/AGENTS.md) 新组件清单的第一步，[docs/web-styling.md](../../../../docs/web-styling.zh.md) 指向该目录，让从样式一侧进来的作者也能到达。
+
+## 如何找出重复
+
+按名字搜会漏。`.badge`、`.tag`、`.chip`、`.configTag` 找不到以角色而非外观命名的胶囊——`PluginCard` 的未保存标记叫 `.pending`，而它的规则与两个文件之外的徽章逐字节相同。能找出它们的是几何特征：同时带有 `border-radius: 999px` 与 `padding: 1px 8px` 的 CSS Modules 规则。本次改动后，这个特征恰好匹配三条规则——`Tag` 本身、下面那个损坏徽章，以及未保存标记保留下来的 `flex: none` 布局类。
+
+<a id="what-stays-local"></a>
+## 保留在原包的控件
+
+机械搜索会把下面这些控件归到被提升的那三类里。它们留在各自的包中，因为那种归并只是表面相似：
+
+- **`ui-trajectory` 的工具栏开关**带 `role="switch"`，但它是 88px 宽的带标签控件、轨道内联，而且当前渲染为 `hidden`。它和 `Switch` 不是同一个部件。
+- **`ui-schedule` 的状态点**是表示下次运行的静态蓝点，逾期转为琥珀色。`StateDot` 没有静态蓝——它唯一的蓝是 `ongoing`，一个动画像素方阵——日程列表里每行一个动画，既说错了含义也说错了观感。
+- **`ui-plan` 的模式 chip** 与 **`ui-conversation` 的 `ReferenceChip`** 都是可交互的：前者是警告色调的按钮，带 hover、focus、disabled 与关闭操作；后者是带自有截断逻辑的 Lexical 原子节点。两者都不是只读徽章。
+- **`ui-trajectory` 的单元格 tag** 与 **`ui-user-questions` 的推荐徽章**使用各自的几何——一个是表格密度下的 6px 圆角，一个是侧栏强调色上 600 字重的 6px 圆角。把它们塞进胶囊基准，改掉的是有意的设计，不是意外的分歧。
+- **`ui-agent-preset` 的损坏徽章**共用胶囊几何，但带着没有第二处使用的实底错误色填充，而且它是自带提示元素的悬停锚点。改用 `Tag` 就得在功能包样式表里保留一份配色覆盖，并依赖跨文件 CSS 顺序来让它生效。
+
+## Alternatives considered
+
+**做一个 `SettingsCard` 原语。** 否决。`.card` 出现在十五个包里，但只有三处带设置页语义，而这三处的差异在行为而不在外观：`ui-settings-plugins` 的 `PluginCard` 暂存编辑，且只在 Host 确认保存后才折叠；`ui-agent-preset` 的卡片可选中；插件清单的卡片是只读的。`PluginCard` 自己的头注释已经记录了它为何不能使用共享折叠行。单个组件将不得不通过 props 接纳全部三种行为，而没有任何一个调用方会用到其中一种以上。
+
+**加门禁，拒绝 `ui-primitives` 之外的 `role="switch"` 或 `.switch` 规则。** 否决。目标是让作者复用已有的东西，不是阻止他们构建。门禁会挂掉一个确实有特殊控件的包——`ui-trajectory` 的带标签工具栏开关正是这种情况——而误拒的代价落在最没法跟它讲道理的作者身上。目录加清单条目针对的是真正的失败原因：作者不知道那个控件存在。
+
+**用额外的 `Tag` props 保留现有的每一种外观。** 否决。插件清单的 5px 圆角与 agent preset 的胶囊是同一类标签的两种形状，两处差异都不是决定出来的。两个都留会把一次意外固化进公开联合，并且让下一个作者去猜该挑哪个。
+
+**扩展 `Pill` 而不是新增 `Tag`。** 否决。`Pill` 高 24px、圆角 12px、字号 12px；徽章基准更密也更圆。合并会产生一个尺寸取决于是否传了 `onClick` 的组件，并抹掉只读与可选中的区分——而目录正需要这个区分来回答"我该用哪个"。
+
+**给 `Tag` 设计 `variant × tone` 双轴 API。** 否决。三个 variant 乘六个 tone 描述十八种组合，其中六种会发布，而且它允许调用方请求没有定义外观的组合。扁平的八成员联合把每个值映射到恰好一种已发布外观。
+
+**让 `pending` 与 `unloading` 不渲染点，而不是新增 `idle`。** 否决。这两行今天显示灰点，在一个目的是统一呈现的改动里把它删掉，等于从清单中拿走信息。
+
+**把复用规则写进根 `AGENTS.md`。** 否决。这条规则只管 `packages/client`，而根文件正好处在 `scripts/doc-budgets.manifest.json` 给它的 1950 词上限上，写在那里就必须挤掉一条不相干的仓库级规则。
+
+## Testing
+
+`Tag`、`Switch` 与扩展后的 `StateDot` 在 `packages/client/ui-primitives/tests` 中各有组件测试，处于每文件 100% 覆盖率门禁之内。`StateDot` 的配色通过读取其样式表来钉住：CSS Modules 在组件测试里解析为类名映射，因此某个状态缺了配色规则时会落到继承色上，而任何渲染断言都不会察觉。
+
+四个迁移后的渲染点保留各自包内原有的测试，未作改动。web e2e 的 golden 是 ARIA 快照，完整的 replay web 套件无需重录即可通过，因为这次迁移保住了每一个 role、无障碍名称与状态——`Switch` 保留带 `aria-checked` 的 `role="switch"`，而由于 `StateDot` 是 `aria-hidden`，插件清单的相位点把 `role="img"` 名称保留在外层包裹元素上。
+
+这同时也是自动化证据的边界。本仓库没有任何门禁比较像素，因此胶囊几何、状态点光晕与字重变化，只能由评审对照 PR 中的明暗两套截图来确认。
+
+## Consequences
+
+- 新的客户端控件现在有一处可查、一处可加，而目录把这次查询变成读一个文件，而不是在四十多个导出上 `grep`。
+- `TagTone` 有八个成员，因为发布了八种外观。加第九个需要一个真的需要它的渲染点，而不是一个对称性论证。
+- 插件清单的标签从 5px 矩形变为胶囊，相位点获得光晕，loading 相位还会有动画。插件设置字段中"未配置"徽章的字重从 400 改为基准的 500。这些都是有意的视觉变更，记录在此，以免后来的读者把它们当成回归。
+- 本次迁移移除了一个 `#b45309` 字面量。插件清单的 `conditional` 标签写的是 `var(--dsw-alias-state-warning-primary, #b45309)`，而这个别名并不存在——真正的 token 是 `--dsw-alias-state-warn-primary`——所以明暗两套主题一直在绘制那个被 [docs/web-styling.md](../../../../docs/web-styling.zh.md) 禁止的硬编码兜底色。
+- 这条规则无法被机械检查。将来的作者仍然可以复制一个控件，只有评审能拦住。这是不设门禁所接受的代价：另一条路会拒绝正当的工作，而上面那份保留在原包的清单就是正当工作确实存在的证据。
+- `ui-primitives` 多出两个各自只有一个消费方的组件。开关尤其如此，提升它是因为它是一个通用控件，也因为正在进行中的插件管理工作会采用它，而不是再加两份拷贝。

 - Use `--dsw-alias-*` semantic tokens in feature components. Do not copy static palette values or write literal colors there.
 - Keep theme selectors out of feature component CSS. Light/dark overrides belong to the theme owner.

-1. Compose through register: add the slot to `SlotMap`, declare it in its parent entry's `children`, and register your component — see the [Slots reference](../../docs/subsystems/slots.md). No other composition route exists.
-2. Type the props as the four shares (`PropsRuntime` & `PropsRenderSlots` & `PropsStore` & inject face) — derive, don't hand-write. Shared/surviving state goes in a `createXXXStore()` factory declared at register; component-private state stays local.
-3. Component tests feed props directly (`createXXXStore().create()` for the store data; plain stubs for framework hooks) and assert behavior without render machinery.
-4. Tokens only in CSS; product copy follows the localization rule above; English comments.
-5. `pnpm run test:gui` green; if the component changes visible assembled output, also run `DSH_SNAPSHOT=replay pnpm run test:web`.

 Compose feature UI from these atoms whenever the web client needs a standard control or an agent-output renderer. They render through React only and take `--dsw-*` design tokens from the theme, so they fit any plugin without importing the theme or the slot system.
 
+<a id="component-catalog"></a>
+### Component catalog
+
+Check this table before writing a control in a feature package. A plugin cannot import another plugin's component, so this package is the only place a control can be shared: reuse what fits, and lift a deliberate visual difference into a prop rather than starting a second copy.
+
+| Export | What it is |
+|---|---|
+| `Button` | Clickable action; `variant` selects `primary`, `ghost`, `outline`, or `toolbar`. |
+| `Switch` | Two-state toggle, 36×20. `label` is required, so the control cannot ship unnamed. |
+| `Input` | Single-line text entry for search boxes and inline forms. |
+| `Menu` | Dropdown of items, separators, and group labels, with nested submenus. |
+| `Pill` | Selectable capsule button for view switchers and filters; takes `active` and `onClick`. |
+| `Tag` | Read-only capsule badge; `tone` selects one of eight palettes. |
+| `StateDot` | Status mark: `done`, `warning`, `ongoing`, `error`, or `idle`. `aria-hidden`, so the render site owns the name. |
+| `ConnectionIndicator` | Inline connection-recovery control across outage, retry, and recovered states. |
+| `DisclosureRow` | 24px compact disclosure that lays title and content side by side. |
+| `Modal` | Centered dialog over a page mask. |
+| `RiskConfirmation` | Sensitive action gated behind an explicit checkbox. |
+| `OnboardingSurface` | First-run stage that holds the application root inert. |
+| `Tooltip` | Hover text on a cloned anchor, placed on one of four sides. |
+| `HoverCard` | Hover preview the pointer can rest on and select from; optional copy button. |
+| `Toast` | Transient top-center banner held for the owner's `holdMs`. |
+| `JsonTree`, `JsonBlock` | Read-only JSON inspection. |
+| `MarkdownText`, `CodeBlock` | Untrusted GFM with TeX math, and highlighted code. |
+| `TerminalBlock`, `ReadBlock`, `DiffBlock`, `SearchBlock`, `WebBlock` | The agent-output card matching each tool-result intent. |
+| `icons/*`, `FishLogo`, `BrandWordmark`, `ReferenceIcon`, `LinkIcon`, `DocumentFileIcon` | Glyphs and brand marks, all riding `currentColor`. |
+
+Three pairs are easy to confuse:
+
+- **`Tag` against `Pill`.** `Pill` is selectable — it takes `active` and `onClick` and drives view switchers and filters. `Tag` is read-only and takes neither. Passing `active` without `onClick` means you want `Tag`.
+- **`DisclosureRow` against a card.** The row lays its title and content side by side at a fixed 24px. A card that stacks a name over a description is a different layout, and belongs in the feature package — `ui-settings-plugins`' `PluginCard` is the precedent and records why.
+- **`FoldToggle` against the exported surface.** It is package-internal and not exported; the output cards use it for their head-tail fold.
+
+Writing your own component in your own package is fine when the need is genuinely specific. What is not fine is copying a control that already exists here — and once a second package needs the same control, it belongs in this package ([decision](../../../.agents/notes/implemented/architecture/2026-09-05-shared-client-control-primitives.md)).
+
 ### Controls and icons
 
 `Button`, `Pill`, `Input`, `Menu`, `Modal`, `Tooltip`, `DisclosureRow`, `StateDot`, `HoverCard`, `Toast`, `ConnectionIndicator`, `RiskConfirmation`, and the `OnboardingSurface` first-run takeover cover the common interaction shapes. The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `LinkIcon` draws the leading category glyph for clickable artifact links — globe, folder, code, image, document, or plain paper, all riding `currentColor` — and `classifyLinkPath` derives a file path's category from its extension. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Every state reserves the widest supplied label and uses fixed icon and text columns, so copy changes do not move or resize the control. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `useAnchoredPosition` and `useAnchoredMaxHeight` keep floating panels and bottom-anchored overlays clamped to the viewport and following their anchor. `HoverCard` keeps its portaled preview reachable across the anchor gap and can expose a copy button through the `copyText` prop. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order ([ranking decision](../../../.agents/notes/implemented/feature/2026-08-04-web-slash-command-fuzzy-discovery.md)).

 只要 Web 客户端需要标准控件或 agent 输出渲染器，就用这些原子组件拼装功能 UI。它们只经 React 渲染，并从主题取得 `--dsw-*` 设计 token，因此无需导入主题或 slot 系统即可适配任意插件。
 
+<a id="component-catalog"></a>
+### 组件目录
+
+在功能包里写控件之前，先查这张表。插件无法 import 另一个插件的组件，因此本包是控件唯一可以共享的地方：合适的就复用，有意的视觉差异提升成 prop，而不是另起一份拷贝。
+
+| 导出 | 是什么 |
+|---|---|
+| `Button` | 可点击操作；`variant` 选择 `primary`、`ghost`、`outline` 或 `toolbar`。 |
+| `Switch` | 36×20 的双态开关。`label` 必填，控件不可能在没有名称的情况下发布。 |
+| `Input` | 单行文本输入，用于搜索框与行内表单。 |
+| `Menu` | 由条目、分隔线与分组标题构成的下拉菜单，支持嵌套子菜单。 |
+| `Pill` | 可选中的胶囊按钮，用于视图切换与筛选器；接受 `active` 与 `onClick`。 |
+| `Tag` | 只读胶囊徽章；`tone` 选择八种配色之一。 |
+| `StateDot` | 状态标记：`done`、`warning`、`ongoing`、`error` 或 `idle`。它是 `aria-hidden` 的，名称由渲染点提供。 |
+| `ConnectionIndicator` | 行内连接恢复控件，覆盖断线、重试与已恢复三种状态。 |
+| `DisclosureRow` | 24px 紧凑折叠行，标题与内容左右排列。 |
+| `Modal` | 页面遮罩之上的居中对话框。 |
+| `RiskConfirmation` | 以显式复选框把关的敏感操作确认。 |
+| `OnboardingSurface` | 首次运行的引导舞台，期间保持应用根节点 inert。 |
+| `Tooltip` | 克隆锚点上的悬停文本，可置于四个方向之一。 |
+| `HoverCard` | 指针可停留、可选中的悬停预览；可选带复制按钮。 |
+| `Toast` | 顶部居中的瞬时横幅，保持时长由所有者的 `holdMs` 决定。 |
+| `JsonTree`、`JsonBlock` | 只读 JSON 查看。 |
+| `MarkdownText`、`CodeBlock` | 不可信 GFM 与 TeX 数学，以及高亮代码。 |
+| `TerminalBlock`、`ReadBlock`、`DiffBlock`、`SearchBlock`、`WebBlock` | 与各类工具结果意图对应的 agent 输出卡片。 |
+| `icons/*`、`FishLogo`、`BrandWordmark`、`ReferenceIcon`、`LinkIcon`、`DocumentFileIcon` | 字形与品牌标识，全部随 `currentColor`。 |
+
+有三组容易混淆：
+
+- **`Tag` 与 `Pill`。** `Pill` 可选中——它接受 `active` 与 `onClick`，驱动视图切换与筛选器。`Tag` 只读，两者都不接受。传了 `active` 却没有 `onClick`，说明你要的是 `Tag`。
+- **`DisclosureRow` 与卡片。** 该行以固定 24px 把标题与内容左右排列。把名称叠在描述之上的卡片是另一种布局，属于功能包——`ui-settings-plugins` 的 `PluginCard` 是先例，并记录了原因。
+- **`FoldToggle` 与对外导出面。** 它是包内组件，未导出；输出卡片用它做头尾折叠。
+
+需求确实特殊时，在自己的包里写自己的组件没有问题。不可以的是复制这里已有的控件——而当第二个包需要同一个控件时，它就该住进本包（[决定](../../../.agents/notes/implemented/architecture/2026-09-05-shared-client-control-primitives.zh.md)）。
+
 ### 控件与图标
 
 `Button`、`Pill`、`Input`、`Menu`、`Modal`、`Tooltip`、`DisclosureRow`、`StateDot`、`HoverCard`、`Toast`、`ConnectionIndicator`、`RiskConfirmation` 与首次运行接管层 `OnboardingSurface` 覆盖常见的交互形态。`ic_ds_*` 图标集与 `FishLogo`/`BrandWordmark` 标记填充品牌与行内图标 slot。`LinkIcon` 为可点击产物链接绘制前置分类图形——地球、文件夹、代码、图片、文档或纸张，全部随 `currentColor`——`classifyLinkPath` 按扩展名推导文件路径的类别。`ConnectionIndicator` 可渲染警告色的断联操作、以独立于 retry 时序的 500ms 节奏推进一至三个点的连接中状态，或成功色的恢复状态。所有状态都为最长的输入 label 预留空间，并使用固定的图标列和文字列，因此文案变化不会移动控件或改变其宽度。它的 owner 提供可见性、恢复驻留时间、本地化 label 与立即重连回调；该原语不使用原生 title tooltip。`useAnchoredPosition` 与 `useAnchoredMaxHeight` 让浮动面板与底部锚定浮层始终钳制在视口内并跟随锚点。`HoverCard` 通过指针离开宽限期让采用 portal 的预览在跨过锚点间隙时仍可触及，并可通过 `copyText` prop 提供复制按钮。 `Toast` 的停留时长由使用方通过 `holdMs` 指定，因为横幅该留多久取决于有多少内容要读；同一个值同时驱动它的卸载定时器与样式表的淡出延迟，两者不可能再错位。 `rankByName` 是 `/` 菜单命令源与 skill 源共享的候选排序器：查询必须是名字的不区分大小写的有序子序列；前缀命中排最前，其次按对齐分数，再按来源顺序（[排名决策](../../../.agents/notes/implemented/feature/2026-08-04-web-slash-command-fuzzy-discovery.zh.md)）。

Subject: [PATCH 04/70] docs(notes): archive low-future-value Agent Notes

Run the dsh-archive-agent-notes audit over every active Agent Note on
current master, judging each record by whether its rationale still guides
work rather than by size or age.

- Archive 453 implemented bilingual triplets (417,882 English words):
  completed UI chrome, narrow adapters, closed bug fixes, implementation
  walkthroughs whose package READMEs, docs pages, generators, or successor
  notes now carry the useful behavior, and 51 records fully superseded by
  a later active note. Keep 201 implemented notes whose ownership rules,
  negative guarantees, durable or wire semantics, security rules,
  reintroduction conditions, or still-tempting rejected alternatives
  remain useful.
- Reject 7 proposals whose premise is gone or whose work shipped in
  amended form under other records; delete 2 rejected notes that no
  longer prevent a plausible mistake.
- Retarget every remaining inbound link to the archived path, and repair
  active prose that named an archived record as the owner of a live fact:
  parenthetical citations drop, ownership sentences redirect to the
  README, docs page, or active note that states the fact, and history
  citations say so. Chinese files link the English archived path because
  the pairing gate treats the frozen tree as outside the bilingual corpus.
- Seal 1,359 new frozen artifacts; existing seals are unchanged and
  outbound links from archived notes are neither inspected nor repaired.
- Regenerate docs/config-catalog.md after the hook-bridge comment edits
  shifted two source line numbers.

 ### Package-owned invariant companions check relationships
 
-`dsh-invariants` registers the configurable `ctx.invariants` service and contains no product checks. A package publishes a `./invariant` ownership companion only for an independently observable runtime relationship; packages without one omit the companion and record the reason in their README. `dsh-session`, `dsh-agent`, `dsh-scope`, and `dsh-agent-loop` provide the initial rules that require trace state or observation of another seam: monotonic sequence numbers, turn and step nesting, tool-call/result pairing, legal agent-status transitions, subject-correct scoped dispatch, and equality between a loop-built request and the request reconstructed from its session-log prefix. Global enablement and package-name regex filters belong to the service ([package-owned invariant service](2026-07-19-package-owned-invariant-service.md); [omission decision](../simplification/2026-08-28-omit-unneeded-invariant-companions.md)).

 When the session companion attaches to an existing or seeded session, it replays the immutable log to rebuild trace state. The service gives each contribution a disposable child fiber, so hot reload is safe in the middle of a turn without giving diagnostics ownership of session storage.

 Key durable, contested choices:
 
 - **The canonical durable log persists every current `SessionEvent` losslessly.** In v2, one `assistant/message` or `assistant/attempt` embeds the exact timed provider stream for an attempt; `deriveMessages()` projects only the surface message. Dropping embedded stream members is tempting, but it loses replay, timing, usage, partial-failure, and diagnostic facts. Removing a complete event likewise requires dense renumbering because `seq = log.length` and `events[i].seq === i`; the [v1-to-v2 migration](2026-09-01-v2-embedded-assistant-streams.md) performs that rewrite explicitly rather than filtering the canonical log.
-- **Append-only; a crashed turn is closed, never truncated.** Flushed events are never rewritten. The [semantic checkpoint policy](../bug-fix/2026-07-21-semantic-session-checkpoints.md) drains the request before model dispatch, a recorded top-level call before tool dispatch, and the complete response/result batch after a step; the loop drains the final turn boundary. Because one interrupted turn may contain substantial valid work, persistence returns its contiguous, parseable events unmodified; the reader owns balancing — resume computes risk-classified error results for unanswered assistant calls, a missing `step/end`, and `turn/end` with `{ kind: 'interrupted' }` (`interruptedTurnClosers`) and appends them through its write handle, while read-only observers add the same closers in memory. The synthetic results keep resumed provider transcripts valid. Only the incomplete fragment of a torn final append is discarded — complete records recovered from it are durably rewritten by the write path before its first new append; a parse error or sequence gap in the committed prefix is corruption and makes the session unloadable.

The [JSONL-only persistence decision](../simplification/2026-08-30-jsonl-only-session-persistence.md) owns removal of the first-party database provider and its deliberate compatibility cut.
-- **Metadata is out-of-log.** Format version, cwd, and lineage are storage concerns, not replayable conversation state, so they live in a `SessionHeader` owned by `dsh-session` and attached to a `Session` via a new readonly `session.header` — never in `SessionEventMap`, never reaching `deriveMessages()`. `createdAt` is non-negative safe-integer Unix epoch milliseconds: live creation and persistence registration reject fractional values, and JSONL validates the decoded header. The alternative (a merge-extensible `session/meta` event as log line 0) was rejected: an in-log event would ride along with a seeded/forked session for free, but metadata is not replayable state, so the explicit out-of-log header boundary is the cleaner cost. (The header was originally split into an immutable `SessionHeader` plus a mutable `SessionSummary` whose union was `SessionMeta`; the mutable summary was later removed as dead state — see [Drop the mutable session summary](../simplification/2026-06-19-drop-mutable-session-summary.md).)
-- **`ctx.agents.create()` and `ctx.agents.resume()` are async factories; resume additionally crosses the persistence boundary.** `ctx.agents.resume({ resumeSessionId })` opens the session's write handle, reads the stored log, and publishes the prepared Session under the persisted id, continuing its projections. The [Session preparation decision](2026-08-05-session-preparation.md) owns the unpublished-Session ownership window. The agent-loop does NOT hard-inject `sessionPersistence` (that would pend non-persistent demos forever); `resume` rejects with a clear error when it is absent.

 The literal types live on the [tasks subsystem page](../../../../docs/subsystems/jobs.md). A producer calls `ctx.jobs.start()` with a kind, label, optional owning `Agent`, optional positive `outputLimitBytes`, and a `run()` function. The runtime completes all failable preflight work before calling `run()` and invokes it once. After `run()` returns hooks, registration commits without another failable step; a producer cannot start work that lacks a collectable job id.

Capacity rejection occurs before `run()` and id allocation, and producer `done` settlement is the only event that releases a stopping task's place.

Omitting it preserves the existing controller behavior, so the runtime does not impose a hidden default on unrelated producer families.

They validate HTTP status, parse `Retry-After` seconds or dates into a positive finite millisecond delay, brand the provider request id when exposed, and distinguish their own timeout from the caller's abort. Provider-specific codes and messages may refine a mapping, but no recovery listener parses them.

 The `agent/request-error` waterfall carries the current `LlmFailure`, an immutable list of prior failures that authorized retries in the consecutive recovery sequence, and the serving registration's immutable retry policy. The loop transports but does not interpret that policy, owns the consecutive failure history, and clears it after a successful model request. Normal `dsh-llm-retry` policy counts durable retry records scheduled by the same exact-provider policy, while `dsh-compaction-basic` keeps its own context-overflow budget. Alternating transient and context-overflow failures therefore consume their owning finite budgets independently; the maximum request count is one plus the sum of the loaded finite budgets.

 For an eligible failure with budget remaining, the one-based transient retry count uses bounded exponential backoff. A valid `providerRetryAfterMs` replaces exponential backoff only when it does not exceed `maxDelayMs`; a longer provider delay causes delegation instead of an earlier retry that violates the provider instruction. Local backoff multiplies by an injected random factor in `[1 - jitterRatio, 1 + jitterRatio]` and clamps the final value to `maxDelayMs`; provider delay is not jittered.

 **The boundary rule:** a durable, replayable fact is a `SessionEvent`; a live interception or a transient/live-object signal is an `agent`/`tools` Cordis event. A turn or step boundary is a durable fact, so it lives in the session log and is read off the `session/event` feed — it is NOT mirrored as an `agent/*` emit.
 
-**Applying the rule to the boundary twins:** all four boundary mirrors — `agent/turn-start`, `agent/turn-end`, `agent/step-start`, `agent/step-end` — are **REMOVED**. No production consumer needs the live `Agent` at a boundary: the ACP bridge correlates its in-flight prompt with the exact `session/event` `turn/start`/`turn/end` pair, and other transcript consumers likewise derive boundaries from the durable stream. See [the remove-boundary-mirror-events Agent Note](../simplification/2026-06-20-remove-agent-boundary-mirror-events.md), which owns that decision.

Removing the emits also simplifies the loop's `closeStep`/`closeTurn` (one append each, no paired emit).
 
 ## Consequences
 
 - The loop no longer emits any boundary mirror; `closeStep` appends `step/end` only and `closeTurn` appends `turn/end` only. `Session.append` owns post-commit observer containment, so a throwing boundary observer cannot change the turn outcome or starve later consumers; an acceptance or internal validation failure still escapes before the boundary enters the log.
 - Tests that observed boundaries via the removed emits now observe the durable `turn/start`/`turn/end`/`step/start`/`step/end` session events — the behavior they pin (boundary ordering, step counting) is unchanged; only the feed they read moved to the canonical one. The tests that exercised a *throwing turn-boundary emit listener* were deleted, because that code path no longer exists (there is no emit to throw from). Per [AGENTS.md "tests document behavior, not golden truth"](../../../../AGENTS.md), the behavior and its test moved (or died) together.
 - The loop marks the step open (`stepOpen = true`) only after `append('step/start')` returns. Internal dispatch validation runs before the log push and may reject without opening a step; post-commit `session/event` observer failures are contained inside `Session.append`. The marker therefore represents exactly the committed boundary that owes a later `step/end`.
-- The full realization of this is [the simplification Agent Note "Stop mirroring durable boundaries as agent events"](../simplification/2026-06-20-remove-agent-boundary-mirror-events.md): all four boundary mirrors are removed and every consumer reads boundaries off `session/event`. `agent/steering` (not a boundary mirror) stayed outside that Agent Note's scope and was removed by its own follow-up, [Remove the `agent/steering` mirror emit](../../archived/simplification/2026-07-04-remove-agent-steering-mirror.md) — it mirrored the durable mid-turn steering `user/message`.

 **边界规则：** 持久的、可回放的事实是 `SessionEvent`；实时拦截或瞬态/活对象信号是 `agent`/`tools` Cordis 事件。轮次或步骤边界是持久事实，因此存在于会话日志中并从 `session/event` 源读取——不会被镜像为 `agent/*` emit。
 
-**将规则应用于边界镜像：** 全部四个边界镜像——`agent/turn-start`、`agent/turn-end`、`agent/step-start`、`agent/step-end`——被**移除**。没有生产消费方需要在边界处获取活的 `Agent`：ACP（Agent Client Protocol）桥接将其进行中的提示词与精确对应的 `session/event` `turn/start`/`turn/end` 事件对关联，其他 transcript 消费方同样从持久流派生边界。见[移除边界镜像事件 Agent Note](../simplification/2026-06-20-remove-agent-boundary-mirror-events.zh.md)，该决策由它负责。移除 emit 也简化了循环的 `closeStep`/`closeTurn`（各只需一次 append，无需配对 emit）。

 ## 后果
 
 - 循环不再 emit 任何边界镜像；`closeStep` 仅追加 `step/end`，`closeTurn` 仅追加 `turn/end`。`Session.append` 负责 post-commit observer 隔离，因此抛出异常的边界 observer 无法改变轮次结果或饿死后续消费方；事件接纳失败或内部校验失败仍会在边界进入日志之前向外抛出。
 - 之前通过已移除 emit 观察边界的测试，现在观察持久的 `turn/start`/`turn/end`/`step/start`/`step/end` 会话事件——它们所锁定的行为（边界顺序、步骤计数）不变；只是读取的源移到了规范源。那些测试*抛出异常的轮次边界 emit 监听器*的用例被删除，因为该代码路径不再存在（没有 emit 可供抛出）。按照 [AGENTS.md「测试记录行为，而非黄金真相」](../../../../AGENTS.md)，行为与其测试一同迁移（或一同消亡）。
 - 循环仅在 `append('step/start')` 返回后才标记步骤已打开（`stepOpen = true`）。内部分发校验在日志推入之前运行，可能在不打开步骤的情况下拒绝；post-commit `session/event` observer 的失败被隔离在 `Session.append` 内部。因此该标记精确表示已提交的、欠一个后续 `step/end` 的边界。
-- 完整实现见[简化 Agent Note「停止将持久边界镜像为 agent 事件」](../simplification/2026-06-20-remove-agent-boundary-mirror-events.zh.md)：全部四个边界镜像被移除，所有消费方从 `session/event` 读取边界。`agent/steering`（不是边界镜像）不在该 Agent Note 范围内，由其后续 Agent Note [移除 `agent/steering` 镜像 emit](../../archived/simplification/2026-07-04-remove-agent-steering-mirror.md) 单独移除——它镜像的是持久的中途 steering `user/message`。

 The shape matches the timeout policy design: a tool author declares a canonical value plus Native renderer, and a policy plugin enforces the deployment's default context budget on rendered content. Tool-specific early spill remains possible for provider acquisition bounds; tool-owned presentation spill may retain a complete acquired canonical value while replacing only presentation. The [canonical tool-output contract](2026-07-20-canonical-tool-output-contract.md) owns that split.

 `SpillLocator` is a [branded](../../../../packages/util/brand) model-facing handle returned by the backend.

 The pi-ai replay state fills that envelope with a versioned, minimal projection of its successful `AssistantMessage`: a response half (source API/provider/model, response id/model, stop reason) and per-block text, thinking, and tool-call signatures. It does not duplicate text or tool arguments already carried by Harness content blocks, and it omits diagnostics, timestamps, usage, and errors. On a later request, `LlmRuntime` gives replay state to the target adapter only when the historical provider and target provider are currently owned by the same adapter instance. That adapter combines the logged Harness content with replay state when it can restore the historical response, and owns any required cross-model or cross-provider conversion. Durable content stays authoritative: an adapter receiving replay state it cannot use — an unknown kind or version, malformed metadata, or a block shape that no longer matches the content — degrades that message to provider-neutral conversion with a diagnostic; a different adapter receives only provider-neutral content plus provider/model fields.

 The driver keeps only a cause-less pre-run marker for queued work cancelled before a turn is claimed. An effective `cancel()` emits the observe-only `agent/cancel-requested` notification with its resolved typed cause before clearing queued and steering work or aborting the holder; notification failures cannot veto the stop, and an idle call emits nothing. Work synchronously queued by a notification observer is included in that clear, while work queued by a later signal abort observer is latched and runs when the aborted activity converges to idle — a `disposed` cancel leaves it parked ([cancel-convergence wake latch](../bug-fix/2026-08-07-cancel-convergence-wake-latch.md)). If a `running` listener synchronously cancels old work and sends a replacement, the driver discards the aborted holder and creates a fresh one for the replacement. Repeated cancellation is first-wins for the active holder, while later calls may still clear newly queued pending work.
 
-The explicit event signatures pass a single payload object: agent-scoped events carry `agent` and `signal` in the payload with `next` last, and the remaining APIs keep `signal` immediately before a waterfall's final `next`. `PreStepContext` and `RequestFailureContext` are retired, with their fields folded into the `agent/pre-step` and `agent/request-error` payloads ([payload-object events](2026-08-06-agent-event-payload-objects.md)). Pre-step entry, request configuration, request-error recovery, model generation, tool execution, approval, turn stopping, and subagent or workflow requests all receive the current signal. Hook bridges must also supply `RunHookOptions.signal`, so a turn cancellation reaches the bash executor's process-group kill and join boundary. `SystemPrompt.assemble()` carries `signal?: AbortSignal` in `AssembleContext` because that object is an explicit request value that can also represent signal-less assembly outside a turn. Listeners may cooperate with the signal but must not retain it to control another turn.

 `ctx.agents` continues to carry only the initiating Agent. Ambient Agent presence does not imply liveness, a current turn, or cancellation authority. The cause reader is private to the loop and states the machine-private slot invariant (only `cancel()` aborts a turn controller, always with a canonical frozen cause) instead of re-validating the reason structurally; no public helper reads a cause off an arbitrary signal. Concurrent Agents isolate both their initiator identities and their turn signals; a child driver shadows the parent initiator while its parent request signal still travels through the subagent seam.

The roster: `ctx.connection` (RPC transport + generation state), `ctx.slots` (registry wrapper emitting `slots/changed`, render entry, renderer installation contract), `ctx.sessions` (list store, current-session state, scope tree), `ctx.loader`, `ctx.theme`, `ctx.i18n`, `ctx.layout` (cross-plugin view navigation), `ctx.conversation` (send/cancel/startSession). Viewing state that used to live in service stores (panel widths, selection, drafts) now lives in entry-declared stores per the [slot system standard](2026-07-22-slot-type-chain-implementation.md).

 **Scope addressing** mirrors the host's agent-scope idiom: services are root singletons whose methods take no sessionId — they read the caller's scope mark (`scopeOf(ctx)`). Inside a session scope, `ctx.conversation.send('hi', 'queue')` targets that session; cross-session calls re-target by switching ctx (`ctx.sessions.scope(id)!.conversation.send(...)`); calling a scoped method from root ctx throws. Client session scopes are minted like host agent scopes (a no-op plugin fiber + a scope-key extend), built lazily on first viewing and torn down only when the session is removed and unwatched — host-session death alone does not tear a scope (it freezes into a read-only viewport).

 - **ConversationSnapshot** (conversation.ts): the top-level immutable snapshot contract. `chat` contains structural `order`, an identity-stable keyed Node reader, Turn/Step indexes, and the timeline; `nodes`, `partial`, `runningCalls`, `turnTimings`, and `turnEnds` are the compatibility slice for unmigrated Trajectory consumers. Pending interactions, queue, running, removal, open state, paging, and prompt errors remain Session facts. **Reference discipline** (the premise of memo and uSES): unchanged substructures and Node values keep their references; one business update replaces only the corresponding key's value unless its order or Location changes. React still subscribes to the Session as the sole observable source, while the framework-provided `useSession(selector)` isolates Node and Location aggregate updates.
 - **SessionManager** (manager.ts): instance cluster + frame entry + the session list. sessionId-bearing frames go only to existing instances (a mux broadcast must not instantiate every session); approval/question `requested` frames are the exception — they never land in history, so they buffer in `pendingBuffers` and replay on instantiation.
 - **Notifier** (notifier.ts): two channels chosen by change source. `markDirty()` (default; frame-driven changes always) batches per microtask — N changes, one notification, one re-render; the flush rebuilds the snapshot cache before notifying. `notifyNow()` (only direct echoes of user gestures) rebuilds and notifies in the same tick — controlled inputs roll the DOM back and jump the caret if their echo defers to a microtask. Frame-driven code using notifyNow collapses batching back to per-frame renders; banned.

 Caller-driven injection and current-step context deliberately use different timing. `inject()` joins the next pre-step available and cannot promise that a request already being finalized will consume it. A listener that must affect that exact request returns the context in `PreStepDecision.messages`; downstream rejection or failure then prevents it from materializing.

 ## Decision
 
-**Composition is one flat assembled tree.** `apps/cli/config/base.cordis.yml` plus `apps/cli/config/web.cordis.yml` holds every row — the host runtime (32 rows), the `api-gateway` row, the `webserver` row, and the `dsh.client` rows (the browser roster; the modules row is simultaneously a host row). No spine bundle: every plugin is one row and every config field is yml-editable. That stance later became repository-wide, with the rows both surfaces share factored into `apps/cli/config/base.cordis.yml` and each surface reduced to an overlay ([shared-base overlays](../simplification/2026-07-29-shared-base-config-overlays.md)). The `dsh-client-hmr` row is an ordinary always-on bundle row (originally appended in code by `--dev`; the flag is retired). Row order carries no load semantics; activation is service-availability driven. The shared audit rejects imports with no fiber, awaits only failed fibers to recover original activation errors, and reports services that leave a fiber `PENDING`; before throwing, it marks those exact rejection reasons through one process checkpoint so `installFailLoud` coalesces Loader's duplicate notification while unrelated unhandled rejections remain fatal. The Node app-boot artifact embeds `@cordisjs/plugin-include` while leaving `@cordisjs/plugin-loader` external, so the include's `EntryTree` and the host bind to one Loader peer instead of splitting a config tree across two Loader implementations.
+**Composition is one flat assembled tree.** `apps/cli/config/base.cordis.yml` plus `apps/cli/config/web.cordis.yml` holds every row — the host runtime (32 rows), the `api-gateway` row, the `webserver` row, and the `dsh.client` rows (the browser roster; the modules row is simultaneously a host row). No spine bundle: every plugin is one row and every config field is yml-editable. That stance later became repository-wide, with the rows both surfaces share factored into `apps/cli/config/base.cordis.yml` and each surface reduced to an overlay ([shared-base overlays](../../archived/simplification/2026-07-29-shared-base-config-overlays.md)). The `dsh-client-hmr` row is an ordinary always-on bundle row (originally appended in code by `--dev`; the flag is retired). Row order carries no load semantics; activation is service-availability driven. The shared audit rejects imports with no fiber, awaits only failed fibers to recover original activation errors, and reports services that leave a fiber `PENDING`; before throwing, it marks those exact rejection reasons through one process checkpoint so `installFailLoud` coalesces Loader's duplicate notification while unrelated unhandled rejections remain fatal. The Node app-boot artifact embeds `@cordisjs/plugin-include` while leaving `@cordisjs/plugin-loader` external, so the include's `EntryTree` and the host bind to one Loader peer instead of splitting a config tree across two Loader implementations.
 
 **Boot glue is a class pair.** `AppCLIEntry` (apps/cli) and `AppWebEntry` (the shell kernel) hold only what must exist independently of cordis: argv facts, the composed patch set, the parsed boot manifest, the module system instance, loading-page handles — everything else lives in plugins. `AppCLIEntry.run()` is three stages: layered env (ambient > cwd `.env` > `$DSH_HOME/.env`, closing the defect above) → patch composition → Loader include boot plus the activation audit. `AppWebEntry.run()` mirrors it browser-side: parse `window.__DSH_BOOT__` into a `BootManifest` (two views: npm-package rows for the module table, cordis-plugin rows for entry composition; malformed wire throws), build the module system, render the loading page, prefetch the `immediately` tier in parallel with Context/Loader setup, **await the prefetch before creating entries** (materialization is `tree.import`'s synchronous require, unprotected by fiber inject waiting; cross-package require edges such as i18n → runtime/client need every immediately-tier factory registered first — an empirically found 10–25% boot race otherwise), adopt the modules entry, create the graph rows, settle, sweep.
 
-**Config sources have one declaration place each.** Bundle yml values are engineering defaults, Settings sections are writable user preferences, CLI flags address their owning launcher rows, and env values enter through yml `!!js` expressions. Patches replace a row's config wholesale. The resolved frontend `distIndex` uses that patch channel as an assembly fact. The transport-independent provider/model default belongs to `ctx.agentDefaultModel`; the [direct headless entry point](2026-08-09-headless-direct-core-entry-point.md) and the Session Controller consume the same state.

 **Transport responsibilities have explicit owners.** `dsh-client-connection` owns the `/api` route, request and response envelopes, browser authentication, Host/Origin checks, exact Fetch route registration, and the shared Typert interceptor seat. `dsh-api-gateway` owns typed Remote dispatch and the multiplexed WebSocket. `dsh-host-webserver` is a plain route-registration plugin: `WebServer` provides `ctx.webServer` (`register(route) → disposer` with duplicate-pattern throw, `renderIndex` rendering — structured `webserver/index-inject` rows, then raw `tapIndex` transforms in registration order — and `port`), listens on activation, answers per-request failures with 400 and logging, and knows no harness concepts. Its socket-backed Node HTTP entry may apply configured gzip through maintained middleware without adding a response-writing service method or changing route owners; the Web Worker tunnel carries identity bytes. The modules node half (`ClientModuleRegistry`, providing `ctx.clientModules`) owns incremental package scanning, the bundle route, the boot injection rows, and `onRebuilt`/`onGraphChanged` notification. The hmr node half owns dev reload through `fs.watchFile` membership and the `/plugins/events` SSE route.

Anchor with `import type {} from 'cordis'`.

 ## Decision
 
-The `dsh` TUI, Web, and headless source launches run `node --import tsx/esm`: tsx's ESM-only hook owns both TypeScript transformation and tsconfig `paths` projection. The root `dsh` script uses that vector directly from the repository root; artifact generation is a separate operation under the [source-launch/build separation decision](../simplification/2026-08-12-separate-source-launch-from-build.md). The CJS hook stays off because the CLI source graph is ESM-only; measured runtime launch to the TUI banner is ~0.7s versus ~1.1s under the full tsx default and ~0.75s under the removed native chain.

 `scripts/tspath-loader.ts` and `apps/cli/src/tsconfig-paths-loader.ts` are deleted. With them went the loader's runtime rule of mapping a workspace import only for declared runtime dependencies — tsx applies the `paths` map unconditionally. Declaration completeness now rests on the static gates alone: `verify-cordis-config` for configured bare plugins, and workspace constraints for manifests. (That runtime rule found real bugs: `dsh-plan-mode` and `dsh-tool-jobs` imported `@deepseek-ai/dsh-llm` while declaring it only in devDependencies; since fixed.)

 ## 决策
 
-`dsh` 的 TUI、Web 与无头源码启动运行 `node --import tsx/esm`：由 tsx 的 ESM-only 钩子同时负责 TypeScript 转换与 tsconfig `paths` 投影。根目录的 `dsh` 脚本直接从仓库根目录使用同一启动方式；产物生成是独立操作，由[源码启动与构建分离决策](../simplification/2026-08-12-separate-source-launch-from-build.zh.md)规定。CJS 钩子保持关闭，因为 CLI（命令行界面）源码图是纯 ESM；实测运行时启动至 TUI banner 耗时约 0.7s，对比完整 tsx 默认形态约 1.1s、已移除的原生链约 0.75s。

 `scripts/tspath-loader.ts` 与 `apps/cli/src/tsconfig-paths-loader.ts` 已删除。随之消失的还有该 loader「仅为已声明运行时依赖映射 workspace import」的运行时规则——tsx 无条件应用 `paths` 映射。声明完整性现在仅由静态门禁保障：配置的裸插件走 `verify-cordis-config`，manifest（元数据清单）走 workspace constraints。（该运行时规则确实发现过真实缺陷：`dsh-plan-mode` 与 `dsh-tool-jobs` 导入 `@deepseek-ai/dsh-llm` 却只声明在 devDependencies；后已修复。）

-**The credential document belongs to the credential provider alone.** No surface loads it into `process.env`. It was `$DSH_HOME/.env` here; the [credentials document split](2026-08-04-credentials-yaml-and-user-environment-layer.md) later moved it to `$DSH_HOME/.credentials.yaml`, so `$DSH_HOME/.env` is the user's ordinary environment layer, holding no provider-managed secret. The genuine launch environment and the invoking directory's `.env` (loaded by the bin) stay the read-only ambient layer, so a composition without the provider resolves keys exactly as before, while a stored key stays file-sourced and writable across restarts — proven by a real restart in the loader composition rather than by a unit assertion about `describe()`.

 **The stored credential has no boundary against the model, and the READMEs say so.** `0600` under a `0700` directory stops other OS users; the model's bash and filesystem tools run as that same user, and the shipped default confines nothing. What the harness does hold to is narrower and stated as exactly that: no surface hoists the document into `process.env`, and the model is never handed a resolved path to it, so reaching the value takes a deliberate read of a path it was not given. An OS-keychain provider — a store the model's processes cannot read at all — is recorded as the real answer rather than implied by a partial one.

 ACP must return a protocol `stopReason`. Its bridge serializes one in-flight prompt per ACP session and owns the interval from admission through whole-Agent idle and ordered update delivery. It correlates the turn that admits the identified ACP message without claiming that every activity in the interval was caused only by that message. A correlated token-limit ending maps to standard `max_tokens`; a correlated model error rejects at the same quiescence boundary; a turnless slot settles as `cancelled` alongside explicit ACP cancellation or disposal. Other normal quiescence reports `end_turn`.

 `@deepseek-ai/dsh-experimental-code-runtime-python` owns the wire protocol intended for a CPython code-runtime provider. Such a provider runs each model program in a fresh `python3 -I` subprocess and bridges binding calls and completion values over the child's fd 3. The host cannot trust that channel: model code has full access to fd 3 and can forge any frame, so every inbound frame is hostile input that the host must validate and rebuild before reading. The protocol also has to carry lossless JSON without the depth limit `JSON.stringify` and `json.dumps` impose, because the seam's `CodeJsonValue` is depth-unbounded.

 **Authoring a preset is an RPC, and a privileged one.** A composition is a file, but "edit it on the filesystem" is not a browser affordance, so the roster gained `read`/`write`/`remove` beside `select`. Connection authenticates authoring, `list`, `select`, and the complete Host API with one browser session: a composition names the plugins a session runs, so reading one is reconnaissance and writing one is arbitrary capability, while choosing a preset grants nothing `session.create` with `agentPreset` did not already grant. The capability is not the preset's to grant either: the deployment's own default already carries `bash` and the filesystem tools, so any caller that may start a session at all can already run commands as this process. Containment is a property of the id (`[a-z0-9][a-z0-9-]*`), checked before it becomes a directory name rather than by inspecting the joined path afterwards; the text is parsed with the loader's own schema and dialect, so a save cannot leave a file no session could load. Shipped presets are refused for writes and deletes, because the deployment's copy is what a broken local preset is compared against — which also makes "duplicate, then edit" the authoring path rather than an afterthought.
 
-**A service with a consumer outside the agent plane cannot move into a preset.** The aggressive split moved the `subagents` registry and its spawn/fork backends into the delegation group's entry-local realm, and `dsh web` then failed to boot: `SubagentRuntime` is a Host row that exposes the browser's cross-session Remote queries (`list`, `prompt`), so it waited forever for a service only sessions provided. A per-session copy is wrong twice over — a provider name registers once, so the second session would have collided anyway. The registry and every shared backend, including the [fixed Codex and Claude Code product providers](2026-08-10-product-subagent-providers-in-shared-host.md), are host-plane; a preset contributes whichever delegation TOOLS its agent should see, and those tools resolve the host registry. `workflows` stays entry-local because nothing outside an agent reads it. Grepping injectors is what should have caught this and did not: the search has to include the host packages, not just the agent-plane ones.

 Resolution is two-anchored by construction: `dsh.profile.bundles` names resolve from the dsh installation first, then the profile directory — so in-box bundles always come from the same installation as the running `dsh` and pnpm never manages them — while bare plugin names in patch rows resolve through the profile directory's Node parent-walk into the maintained flat fallback `$DSH_HOME/profiles/node_modules` (one symlink per package the installation's app and bundles depend on, healed on every launch).

 When business logic deliberately changes a materialized Node to hidden, it leaves visible order and remounts when visible again. This is explicit business withdrawal of presentation, distinct from the stable-Seat guarantee for running→settled.
 
-The concrete Tool renderer remains governed by the [`ui-tool ownership decision`](2026-08-08-client-tool-presentation-ownership.md). Tool Definition supplies recursive root/subcall data, and `ui-tool` dispatches concrete presentation by the Tool-name keyed slot.

 Trajectory registers its own target and business Definitions against the same Assembler and `SessionEventLikeEntry` window as Chat. Its target builder preserves the stage-oriented read model without consuming the Chat Builder's legacy slice or running an independent history fold. Chat and Trajectory keep independent scalar and packed Assistant reducers; target-specific Definitions do not change the shared Context, Reader, or Location contracts.

 The harness credential plane could only express one kind of secret: a value behind an environment-variable name. `CredentialRef` is a POSIX identifier, resolution layers the process environment over a managed file and `.env` fallbacks, and every consumer reads it per operation. That covers an API key exactly and covers nothing else.
 
-Some credentials are not values a deployment can be told to store. They are obtained — by a conversation with a human who opens a page, approves an account, and pastes a code back — and what comes out is a token document with a refresh half that rotates behind the user's back. pi-ai models this directly (`Credential = ApiKeyCredential | OAuthCredential`, an app-owned `CredentialStore`, `Models.login()`), and the harness had nowhere to put any of it. `PiAiAdapter` built its collection with `createModels()` and no options, so the store was pi-ai's in-memory default: empty at every boot, discarded on every configuration change. `openai-codex`, whose only method is OAuth, therefore failed every request with `Provider is not configured` — [withheld from the directory](../bug-fix/2026-08-13-oauth-only-providers-withheld.md) as a release fix, which removed the broken offer without adding the capability.

 Two further gaps followed from the same missing plane. A provider's own ambient discovery ran against the raw process environment, so a key held by the credential seam was invisible to it and a local credential file was never even looked for. And a login had no surface to run from, because nothing in the harness could ask a human a question on a plugin's behalf.

 ## Decision
 
-This decision builds on the split between host projection state and client views in [Session projection state and client views](2026-08-19-session-projection-state-and-client-views.md).
+This decision builds on the split between host projection state and client views in [Session projection state and client views](../../archived/architecture/2026-08-19-session-projection-state-and-client-views.md).
 
 Every host reader treats the projection registry and its required key as mandatory state. A plugin either declares `sessionProjections` as a required injection or resolves the registry and key explicitly and throws on the first dependent access. Official compositions mount the registry before those plugins. `ApiProxyService` follows the required-injection form; the lower-level `createApiProxy` factory remains tolerant for isolated tests and diagnostics.

 ## 决策
 
-本决策建立在[会话投影的 host 状态与客户端视图](2026-08-19-session-projection-state-and-client-views.zh.md)所定义的拆分之上。
+本决策建立在[会话投影的 host 状态与客户端视图](../../archived/architecture/2026-08-19-session-projection-state-and-client-views.md)所定义的拆分之上。
 
 每个 host 读取方都把投影注册表及其所需 key 视为必需状态。插件要么把 `sessionProjections` 声明为必需注入，要么显式解析注册表与 key，并在第一次依赖它们的访问时抛错。正式组合在这些插件之前挂载注册表。`ApiProxyService` 采用必需注入形式；较低层的 `createApiProxy` factory 对隔离测试和诊断保持容错。

 **`verify-client-ui-i18n` enforces source ownership.** The TypeScript-AST check discovers every package `src/client` tree that contains TSX, all helper TS files under `packages/client/ui-*`, and the web app source. It rejects natural-language JSX text, copy-bearing attributes and component props, literal JSX branches, label/copy data, named copy helpers, string-returning display formatters, and destructuring defaults. Locale dictionary owners and immutable language tokens are the narrow syntactic exclusions. Discovery refuses a narrowed corpus, unit fixtures pin admitted and excluded forms, and the check runs in the static CI and `hygiene` graphs. Dictionary-key parity remains a separate check: one gate proves copy enters the locale path, while the other proves both shipped languages implement that path.

Cross-realm discrimination always reads the structural marker, and any new transport (a worker, a bundle split) must carry that marker or an equivalent marker frame across, or failure values degrade into plain `Error`s.

The same case pins the boot path end to end: it caught the [HMR initial-scan boot deadlock](2026-08-03-hmr-initial-scan-boot-deadlock.md) that silently exited 13 with the terminal stranded.

 The owning Host halves register three schemas: optional `locale.preference` (`zh` or `en`, where absence delegates to the browser), `ui-theme.preference` (`light`, `dark`, or `system`, default `system`), and `ui-conversation.busyEnter` (`queue` or `steer`, default `queue`). The local settings provider stores explicit choices in `$DSH_HOME/settings.yaml`, which resolves to `~/.dsh/settings.yaml` under the default home. The API proxy serves every registered namespace behind Connection's browser authentication; field roles still redact secrets.
 
-`dsh-client-ui-settings` owns one browser-wide settings describe mirror and provides `ctx.settingsScope.bind(spec)` as a per-namespace selector over it. The mirror installs `settings/document-updated` and `connection/reset` listeners before starting its background read, so no settings transport can block plugin activation and an invalidation cannot fall into a read-before-subscribe gap. Each bound scope publishes a snapshot store (status, section value, revision, writability, host/memory mode) the domain service subscribes to, without adding a wire read or listener of its own. The default decoder validates each incoming section against the namespace's own serialized wire schema, rehydrated through the colocated `ctx.settingsSchema` service, so domains carry no hand-written wire guards. Domain services take the scope as an ordinary constructor collaborator, publish their provisional defaults immediately—browser-derived locale, system theme, and Queue—then adopt an accepted Host section without writing it back; a service constructed without a scope (standalone dictionary or policy fixtures) simply stays process-local. The shared read and invalidation lifecycle is specified by the later [settings describe mirror decision](../architecture/2026-08-17-settings-describe-mirror.md).

 User changes update the live service synchronously and queue a `settings.mutate` path operation through `scope.set`. The scope serializes gestures, sends the latest known namespace revision as `expectedRevision`, records every successful revision, and lets only the latest write settlement republish live state. A rejected or failed latest write reloads Host state. Disposal rejects new work, skips queued operations, suppresses publication by the in-flight operation, and waits for that operation to settle before the plugin reaches quiescence.

 ## Problem
 
-`Agent.cancel(cause, { keepInbox: true })` returns immediately after firing the abort signal, but the active driver may not have converged to `idle` yet: LLM stream teardown, tool cancellation, and the `turn/end` append all unwind asynchronously after `abort()` returns. A waking send arriving in that window was placed into `next-turn` while `wakeDriver()` returned early on the still-`running` phase, and the exiting driver never replayed the wake — the message stayed parked until another waking send arrived. The same dropped-wake window existed around aborted `runMaintenance` activities. Several tests enshrined the parked behavior ("waits for another wakeup"); the bug broke both `session.cancel` and the `subagent.interrupt` composition path (issue #1838). The owning cancellation and send contracts are the [explicit turn cancellation](../architecture/2026-07-16-explicit-turn-cancellation.md) and [unified send](../architecture/2026-07-22-unified-send-and-coalesced-user-messages.md) decisions; the production `keepInbox` consumer is [web stop preserves queue](2026-07-31-web-stop-preserves-queue.md).

 ## 问题
 
-`Agent.cancel(cause, { keepInbox: true })` 在触发 abort 信号后立即返回，但活动 driver 可能尚未收敛到 `idle`：LLM（大语言模型）流拆除、工具取消与 `turn/end` 落盘都会在 `abort()` 返回后异步展开。在该窗口内到达的唤醒 send 被放入 `next-turn`，而 `wakeDriver()` 对仍处于 `running` 的 phase 直接返回，退出的 driver 也从不重放这次唤醒——消息会一直停放到下一条唤醒 send 到达。被中止的 `runMaintenance` 活动周围也存在同样的唤醒丢失窗口。多个测试固化了停放行为（「等待下一次唤醒」）；该缺陷同时破坏了 `session.cancel` 与 `subagent.interrupt` 组合路径（issue #1838）。取消与发送约定由以下既有决策定义：[显式轮次取消](../architecture/2026-07-16-explicit-turn-cancellation.zh.md)与[统一发送](../architecture/2026-07-22-unified-send-and-coalesced-user-messages.zh.md)；生产环境中的 `keepInbox` 消费方是[Web 停止保留队列](2026-07-31-web-stop-preserves-queue.zh.md)。

 The Host Connection plugin validates `recovery` in its configuration and injects the resolved, non-secret timing into each page through `webserver/index-inject`. The Client validates that bootstrap input before providing Connection; direct loop options may override it. Timer values must be positive integers within the browser timer range, and the backoff factor must be finite and at least one. The shared resolver explicitly rejects `NaN`, which range comparisons alone cannot exclude. A factor of one selects continuous fixed-cap retries. Changes to Host timing apply to subsequently loaded pages.

The waterfall's returned assembly is final, so whoever changes these inputs owns preserving a viable PTC mode protocol when the deployment expects PTC mode to remain usable; no restoration pass overrides deliberate composition.

The default summarizer resolves its target from explicit config, the latest logged routed target, then agent options, and records the provider/model pair after any `llm/stream` routing.

 The launcher is a ~300-line C program (plain C11 over the raw Landlock UAPI — no libraries beyond a statically linked musl, so the audit surface is that one file plus the kernel's stable syscall contract): `--ro <path>` / `--rw <path>` grants, `--`, the wrapped argv; it installs the ruleset on itself and `exec`s (rulesets are inherited across `execve`, and it sets `no_new_privs` before restricting); `--probe` enforces a maximal ruleset in a short-lived child and exits 0 only when the kernel actually enforces; every launcher failure exits 125 without running the child and prints a fatal `landlock-run:` line. A successfully exec'd child may also return 125, so status alone is not launcher evidence. An older ABI prints the exact `landlock-run: partial enforcement (older Landlock ABI)` notice before it executes the child, so that line is not fatal evidence.

 `dsh-bash-sandbox` extends `LocalBashExecutor`, hands `ctx.sandbox` the exact `['bash', '-c', command]` argv, and directly spawns the provider result. This leaves shell semantics and `BASH_ENV` on the inner Bash after the shipped native runner establishes confinement. A provider error propagates unchanged. A pre-process rejection counts as a runner failure only when the caller-owned workdir is independently usable and Node reports `ENOENT` or `EACCES` with either an `error.path` equal to provider argv[0] or, when `error.path` is absent, an exact `syscall: 'spawn <runner>'`; a present path also requires `syscall: 'spawn'` or the exact `spawn <runner>`. Other codes, invalid workdirs, resource failures, unrelated syscalls, and unstructured rejections retain local command-start semantics. Foreground execution converts runner failures to `SANDBOX_UNAVAILABLE` with the original detail; an asynchronous background rejection stamps `runnerFailed: true`, `denied: false`. A `SubprocessRuntime` that synchronously throws the same runner-identifying shape makes background start throw `SANDBOX_UNAVAILABLE`, while other synchronous errors propagate unchanged. After a process starts, foreground and background use one runner-failure classifier that requires the rule's exit-code check and a remaining fatal line after informational exclusions. A match takes priority over denial: foreground execution throws `SANDBOX_UNAVAILABLE` with that fatal line as detail; a settled `ShellProcess` stamps `sandbox.runnerFailed`, and the bash producer renders it through generic `job_output`.

 ## Problem
 
-The [agent-instructions plugin](2026-06-24-workspace-context.md) probed each instruction candidate with `ctx.fs.lstat` before resolving, rejecting any final-component symlink so a repository-owned link could not point instruction loading at content outside the workspace. That no-follow invariant blocked a deliberate, supported setup: a user who symlinks `$DSH_HOME/AGENTS.md` — or a project `AGENTS.md` — to a canonical instruction file kept elsewhere, sharing one house-style file across tools and homes, saw the link silently ignored. It also forced content dedup to treat the ubiquitous `CLAUDE.md → AGENTS.md` mirror as a special skipped case rather than an ordinary duplicate. The repository owner asked to follow symlinked instruction files unconditionally across every scope, accepting the residual trust-boundary risk recorded below.

The repository owner asked to follow symlinked instruction files unconditionally across every scope, accepting the residual trust-boundary risk recorded below.
 
 ## Decision
 
 Instruction discovery no longer inspects the final component with `lstat`. Every candidate — the user-global `$DSH_HOME/AGENTS.md`, each base candidate, and each local-overlay candidate — is resolved and its resolved target is stat-ed, at baseline composition and at each `tools/post-execute` reconciliation alike. A symlink whose target is a regular file loads that target's content; a resolved non-file target (including a link to a directory) is a confirmed absence that removes the scope like a missing file; a `resolve` or `stat` exception is classified as temporarily unavailable and never removes an already-loaded scope. `nodeStatFile` calls `stat` (host path) and `fsStatFile` calls `resolve` then `stat` (provider path); neither calls `lstat`.
 
-A followed symlink is an ordinary file for every downstream step. It participates in per-directory content dedup ([load-all + dedup note](2026-07-21-instruction-load-all-dedup.md)), so a `CLAUDE.md` that symlinks its sibling `AGENTS.md` now resolves to identical content and collapses like any byte-identical real duplicate instead of being skipped as a special case.

 ## 决策
 
 指令发现不再用 `lstat` 检查末段。每个候选（用户全局的 `$DSH_HOME/AGENTS.md`、每个基础候选，以及每个本地覆盖候选）都会被解析，并对其解析后的目标做 stat，基线组合时与每一轮 `tools/post-execute` 协调时一视同仁。一个目标为常规文件的符号链接会加载该目标的内容；一个解析后的非文件目标（包括指向目录的链接）是被确认的缺失，会像缺失文件一样移除该 scope；一个 `resolve` 或 `stat` 异常被归类为暂时不可用，且从不移除已加载的 scope。`nodeStatFile` 调用 `stat`（宿主路径），`fsStatFile` 先 `resolve` 再 `stat`（提供方路径）；两者都不调用 `lstat`。
 
-一个被跟随的符号链接对下游每一步都是普通文件。它参与按目录的内容去重（[加载全部并去重说明](2026-07-21-instruction-load-all-dedup.zh.md)），因此一个符号链接指向其同级 `AGENTS.md` 的 `CLAUDE.md` 现在会解析到相同内容，并像任何逐字节相同的真实副本一样被合并，而不再作为特例被跳过。

Buffer-free on-demand capture uses the same one-record-per-event mapping through an optional inclusive boundary.

 ## Consequences
 
-A deployment adds one `cordis.yml` entry with an OTLP endpoint and explicitly selects `FULL` to stream lifecycle-local canonical events into an OTel-compatible stack or `FEEDBACK_ONLY` to replay a lifecycle-local canonical-log prefix when feedback is recorded. `DISABLED` is the [default](2026-08-10-telemetry-default-off.md) and constructs no reporting pipeline; removing the entry remains a silent opt-out, while the disabled mode keeps the local feedback warning. A rule-free deployment exports each event body exactly as captured — including every assistant chunk and any credentials embedded in file contents or command output — so a deployment crossing a trust boundary must mount `session-telemetry/record` listeners, and both READMEs state this plainly. Where rules are mounted, exported bodies can differ from canonical log bytes, so receivers must not treat telemetry as a byte-exact replica; the log remains the source of truth. Same-object replay after lost cursor state can duplicate lifecycle-local ledger rows, and crash durability remains out of scope until the outbox decision above is revisited.
+A deployment adds one `cordis.yml` entry with an OTLP endpoint and explicitly selects `FULL` to stream lifecycle-local canonical events into an OTel-compatible stack or `FEEDBACK_ONLY` to replay a lifecycle-local canonical-log prefix when feedback is recorded. `DISABLED` is the default ([`dsh-session-telemetry-otel` README](../../../../packages/session/session-telemetry-otel/README.md)) and constructs no reporting pipeline; removing the entry remains a silent opt-out, while the disabled mode keeps the local feedback warning. A rule-free deployment exports each event body exactly as captured — including every assistant chunk and any credentials embedded in file contents or command output — so a deployment crossing a trust boundary must mount `session-telemetry/record` listeners, and both READMEs state this plainly. Where rules are mounted, exported bodies can differ from canonical log bytes, so receivers must not treat telemetry as a byte-exact replica; the log remains the source of truth. Same-object replay after lost cursor state can duplicate lifecycle-local ledger rows, and crash durability remains out of scope until the outbox decision above is revisited.

 Each captured value becomes a source-tagged `sandbox/mode` or `approval/policy` event appended during the child factory's unpublished setup. The session constructor has already fixed `Session.firstLiveSeq` after the constructor seed, while `Session.inheritedEventCount` keeps the exact fork-prefix length, so the inherited facts follow fork history without changing its lineage cut. Lifecycle-local telemetry starts at `firstLiveSeq`, so it excludes the constructor seed and includes these unpublished-setup events. Existing last-event-wins folds therefore make the delegation snapshot beat stale fork history and let a later child switch beat the snapshot. A grandchild folds its parent's logged state, so the rule composes without another inheritance mechanism.

 每个捕获值都会成为子 agent 工厂在未发布设置阶段追加的一条带来源标记的 `sandbox/mode` 或 `approval/policy` 事件。会话构造函数已把 `Session.firstLiveSeq` 固定在 constructor seed 之后，而 `Session.inheritedEventCount` 保留精确的 fork 前缀长度，因此继承事实会排在 fork 历史之后，却不改变其谱系 cut。生命周期本地遥测从 `firstLiveSeq` 开始，因此排除 constructor seed，并包含这些未发布设置事件。因此，既有的末事件胜出折叠会让委派快照压过陈旧的 fork 历史，并让子 agent 后续的切换压过该快照。孙代 agent 会折叠其父级已记录的状态，因此无需另一套继承机制即可组合此规则。

The web UI shows per-sub-call running rings live (fixture emits start/settle pairs; jsdom pins the running shape; the runtime spec pins in-place settlement, out-of-order completion, and callTime pairing). Trajectory/waterfall sub-call spans draw truthful timing from the pair.

 ## Decision
 
-The rows that are not surface-specific move into [`base.cordis.yml`](../../../../packages/bundle/base/cordis.patch.yml), and three more join them: `tool-session-query`, `tool-str-replace-editor`, and `repeat-tool-reminder`. Web search moves there too; its [deployment decision](2026-07-31-web-default-search.md) owns the security boundary while the shared base owns its surface-neutral mount. Both surfaces assemble the same roster, including fixed `glob` and `grep` members because `dsh-tool-fs-search` spawns the [packaged ripgrep binary](../architecture/2026-08-01-packaged-ripgrep-search.md). Two later decisions narrow that roster: the [session-search decision](2026-08-02-session-search-not-shipped-default.md) keeps `tool-session-query` opt-in, and the [single-editor decision](../simplification/2026-08-10-default-presets-single-editor.md) keeps `tool-str-replace-editor` out of the general-purpose presets while retaining it in `minimal`.

 Two rows stay surface-specific. `tmux-context` is TUI-only because a browser surface has no terminal multiplexer to describe. `session-reference` is TUI-only because it drives the shared session-query index from the launcher's process-local path, and the browser sidebar reconciles that index on its own first search.

 ## Consequences
 
-The same model gets the same tools on both surfaces, and the difference that existed for no recorded reason is gone. The tests assert the twenty unconditional names exactly and pin `glob` and `grep` as fixed members on both sides, so a later change that alters only one surface fails a check instead of shipping quietly; the [session-search-not-shipped-default decision](2026-08-02-session-search-not-shipped-default.md) is exactly such a later change, and both tests moved with it.

 DeepSeek search uses the same `DEEPSEEK_API_KEY` credential reference as the official conversation adapter. The provider resolves that reference inside every search through the optional `ctx.credentials` service; only a composition without the seam falls back to the launching process environment, and a non-empty literal `apiKey` remains the programmatic last resort. A stored or rotated Web Models key therefore reaches the next search without restarting or retaining the value on the provider. Because `WebSearchProvider.available()` is synchronous, it treats an installed resolver as locally usable and missing dynamic credentials fail the operation with the provider-specific `WEB_PROVIDER_CREDENTIAL_MISSING` code while the stable tool schema stays registered.

 - **Windows reality is pinned where bash has no analog**: every command runs under a UTF-8 output preamble so the Windows PowerShell 5.1 fallback cannot garble non-ASCII output through the UTF-8-decoding collector, and the prompts teach that Windows forced termination settles as exit 1 without a signal marker.

The provider deliberately omits `settingSources`, so the SDK reads the host's normal user, project, and local Claude settings relative to the parent Session cwd. It neither copies nor filters those settings and does not create or modify login state. Remaining permission prompts are denied, MCP elicitation is declined, and blocking dialogs fail closed instead of waiting for a user interface the provider does not own.
 
-The provider publishes only after both the SDK `Query` and a live managed CLI handle exist. It consumes the complete SDK stream and completes only when a `result` message has `subtype: "success"`, `is_error: false`, and a nonblank `result`, and the iterator then ends normally. The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) owns every non-success action category, stage, process outcome, and its ordering with a contributing permission decision. Local cancellation wins and becomes `aborted` without either diagnostic fact.

 Startup rollback and published disposal close the SDK query, abort the per-run controller, invoke shared process-tree termination, and wait for whole-tree exit. `Query.close()` expresses graceful protocol intent but does not replace the subprocess owner's exit proof. An unpublished failure exposes only fixed `query-start` facts; a published process failure can expose its independent exit code and signal; an independent cleanup rejection exposes `teardown`. Original SDK, Host, and cleanup errors remain on internal cause chains and logs rather than entering the diagnostic.

 Each product owns branch-complete package tests, a required keyless real-product spec, a Loader composition e2e, and a credentialed DeepSeek e2e. The keyless product tier uses the exact official distribution under test, a non-empty fake product key, an isolated temporary workspace and product home, and a loopback fixed-answer model. Missing product requests, wrong authentication, altered task text, a non-exact answer, a skipped real product, or a surviving managed handle fails the required test. The Codex Loader fixture exposes two named Codex instances and tools; the Claude Code Loader fixture exposes the default Codex tool plus two named Claude Code instances and tools. Both fixtures include generic Job controls and start neither product process. The credentialed tier starts the same production provider and real product with a runtime-only key, requires a unique nonce from the fixed official DeepSeek service, and proves quiescence again; it self-skips only when a local operator supplied no key, while trusted CI preflights the secret.
 
-The Codex evidence pins `@openai/codex@0.149.1`, `codex-cli 0.149.1`, and all six optional platform aliases. Its generated schema proves optional `ThreadStartParams.model`; the real-product spec observes omitted-model inheritance, two explicit instance models, the package-local wrapper argv, exact Bearer key, original task, byte-exact final answer, native permission modes, explicit dangerous-bypass writing in suite-owned temporary storage, and wrapper/native whole-tree exit. An isolated wrapper fixture proves missing-payload failure without host fallback, named instances retain separate models, environments, and modes, and production never resolves a host `codex` from `PATH`. The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) owns failure, process-outcome, and final presentation evidence.

Package tests prove that production never resolves host `PATH`, omits the executable override, and forwards the SDK-selected Windows `claude.exe` without a batch shim.

This note's provider lifecycle keeps native settings and behavior while shared services retain the sole ownership of job settlement and process-tree quiescence.
 
 Every delegation pays for a fresh product process and independent model context. Successful product payload remains final assistant text; a failed product run may separately expose the shared safe diagnostic containing provider-owned permission facts and safe product failure categories. Background scheduling additionally exposes generic Job ids, status, completion notices, and collection or cancellation results. Both products use Bundle-pinned platform CLIs plus native account and workspace settings and the selected Provider permission mode; a supported optional instance model overrides only that run's native model selection. Credentialed e2e runs also spend external API quota and depend on the official DeepSeek endpoint; deterministic protocol, failure, cancellation, and approval coverage remains in the keyless tier. The providers do not resume sessions, stream progress, accept new human interaction, roll back tool or file side effects, or impose a wall-clock timeout.

 Peer communication is a Lead-log mailbox. `team/message/queued` is appended and flushed before delivery. The target message carries the stable message id and sender identity in both durable source metadata and a short model-visible prefix. A target receipt is acknowledged with `team/message/delivered` only after its pending inbox item or recorded user message is flushed. Immediate admission is serialized per target in queued-log order, recovery retries queued-minus-delivered in the same order, and delivery folds live or persisted target inbox/history state before cold resume. Every current-version Team payload is runtime-validated before entering replay state. The Team runtime tracks dispatch and asynchronous acknowledgement work from synchronous admission until settlement; disposal closes admission and awaits both before removing the service. Current waiters wake only after the owning Team event flush succeeds.
 
-`send_message` always attempts Steer delivery. A running target receives the message at the nearest step boundary, an idle target starts a turn, and an inactive teammate cold-resumes. Success means the message is already durable even when temporary delivery failure leaves it queued. The mechanism provides process-local retry and target-Session de-duplication, not a cross-process exactly-once claim. The [Team Steer messaging decision](../simplification/2026-08-30-team-send-message-steer.md) owns the single-tool scheduling rationale.

 Shared tasks are complete snapshots with Team-local ids and monotonic revisions. Every mutation carries `expectedRevision`. Any member creates, reads, or claims a ready unowned task; the owner or Lead edits and transitions it, while only the Lead assigns another member. Numeric task ids remain within the safe-integer allocation range, and exhaustion fails without reusing an id. Dependencies must name non-deleted tasks and form a complete DAG. Deleted tasks are retained tombstones. `writeScopes` are normalized path prefixes that produce overlap diagnostics but never block claim or authorize a write.

 **Reuse `kind` as the form.** One discriminant is simpler, and `agent-instructions` is already 1:1 with its form. This design loses information when several producers share one form: three shipped producers emit runtime snapshots, and combining them into one kind would make it impossible to tell which producer supplied each message. Separate `kind` and `form` fields record the producer while allowing several producers to share one presentation.

 This supersedes one fact of the [background-job runtime decision](../architecture/2026-06-20-generic-long-running-tool-runtime.md) — that completion never wakes an idle owner — and adds teardown as a `reported` setter. That note keeps every other task-runtime decision and is updated in place rather than replaced.
 
-The delivery machinery was never the obstacle. `Agent.send(message, target, wakeup)` has covered the `target` × `wakeup` matrix since the [unified send decision](../architecture/2026-07-22-unified-send-and-coalesced-user-messages.md), and `wakeDriver()` already handles idle, maintenance, and cancelled-converging phases. The missing piece was the policy choice of which lane a completion takes, plus the bound that choice needs.

 ## Decision
 
-The shipped Web minimal preset exposes persistent `bash` and `str_replace_editor`; the standalone profile exposes persistent `bash` on Linux/macOS or `pwsh` on Windows, plus the same editor. Both mount no context-compaction provider, suppress every `dsh-system-prompt` runtime-context contribution for fresh sessions, and run the editor against `@deepseek-ai/dsh-fs-local`. The Web preset isolates `ctx.fs` inside the agent entry and mounts `fs-local` beside the editor, so other Web agents retain the host filesystem provider. Its persona remains the fixed complete prompt owned by the earlier [minimal-preset composition decision](../bug-fix/2026-08-10-minimal-preset-owns-rl-composition.md) and applies runtime-context suppression only to that agent scope. The standalone spine forwards the same setting to its process-owned system-prompt service. The Web host retains its sandbox and approval services; the standalone profile mounts a danger-full-access sandbox policy and no approval service. Neither contributes model-facing policy context.

 `DSH_SYSTEM_PROMPT` selects the standalone persona, and `DSH_CONTEXT_WINDOW` supplies fallback capacity for a model without exact catalog metadata. The SDK client's JSON-RPC `initialize` request is the sole runtime model selection. [`minimal.py`](../../../../python/sdk/examples/minimal.py) may read `DSH_MODEL` only as the command's default `model` argument; an explicit `--model` needs no matching child environment value. Endpoint and credential variables stay owned by the DeepSeek adapter's existing environment-resolution path.

Native permission prompts, user dialogs, or MCP elicitation therefore cannot wait for a person, but relying on either product's ambient default can still select an interactive mode. A deployment also needs to choose broader native modes without giving the parent model or one tool call a way to raise its own authority.

The [minimal-diagnostics decision](../../archived/simplification/2026-08-21-product-subagent-minimal-diagnostics.md) owns both products' non-permission action categories, lifecycle stages, HTTP facts, and process outcomes carried by the same field.
 
 Each product's permission fact contains only the effective mode, request category, unattended decision, and a fixed safe reason. Claude Code derives those facts from SDK callbacks and `permission_denied` messages. Codex derives them from app-server requests, declined items, and structured `sandboxError` terminals. Raw stderr is forwarded to the Host but is neither classified nor copied into the diagnostic. Both Providers place their failure line before the latest contributing permission fact. A successful result returns only the strict final answer; local cancellation remains `aborted` without permission detail; an unpublished startup failure still rejects `start()`. The Provider never adds either diagnostic fact to assistant output, structured output, or `subagent/end.lastAssistantMessage`.

A [bounded inline fallback](../../archived/bug-fix/2026-08-21-deepseek-files-inline-fallback.md) sends the same deterministic request versions when file resolution fails.

Uploads request seven days by default and record the returned `expires_at`; a mapping with no more than one hour remaining is replaced without a preceding retrieve call. The index never stores the API key.
 
 An upload is indexed only after the response returns a complete file object, matching byte count, and `expires_at`. A missing or inconsistent response leaves no local mapping, so a later request uploads again. Concurrent upload resolution for one scoped `variantId` shares one provider operation; one waiter cannot cancel another, and the upload stops when every waiter has cancelled. A malformed upload index is an empty cache and is replaced on the next successful upload; filesystem I/O failures remain errors. If chat reports expired, deleted, missing, or invalid ids and names one or more ids used by the request, only those mappings are removed. A stale-file response without a specific id removes every mapping used by that chat attempt. The affected request bytes are uploaded again and chat is retried once. A second stale rejection clears the mappings identified by its response and returns the error without a third chat attempt. One upload quota error first lists the configured number of oldest harness-owned `dsh-` files, then deletes that collected set and retries once; deleting after pagination keeps provider cursors valid. Public file operations expose list, retrieve, delete, one-variant release, and namespace-wide release. Every Files request carries the shared Harness `User-Agent`. The client enforces the documented 128MiB upload limit, 32MiB chat-image limit, 10,000-file and 25GiB quotas, and one-hour to 30-day expiry range.

 The shared dsh base resolves an unset or empty `DSH_TELEMETRY_MODE` to `FEEDBACK_ONLY` instead of `DISABLED`. Nothing is uploaded before the user records `/feedback`. On a Session object already captured, each feedback uploads the suffix after the last handoff through that exact event. A new object starts at its constructor boundary: a fresh Session begins at seq 0, while a forked, resumed, or migrated Session excludes its constructor seed and begins with this lifecycle's `session/end-seed`. The acknowledgement's sharing disclosure therefore matches the released lifecycle-local prefix. `FULL` and `DISABLED` remain explicit `DSH_TELEMETRY_MODE` overrides, any non-empty `DSH_TELEMETRY_DISABLED` remains the authoritative pre-load hard opt-out, and the plugin's own omitted-`mode` default stays `DISABLED`: the default changes only in the shared base's config expression, where deployments already override it.
 
-This supersedes the session-backend default of the [default-off decision](2026-08-10-telemetry-default-off.md), accepting the user's explicit feedback action as the release authorization that note required a deployment setting for. That note's hard opt-out and its launcher-feed history remain current, and the [default-mount decision](2026-07-31-web-telemetry-default-mount.md) continues to own the endpoint, batching cadence, and exit-drain settings.

 - **Paired sibling files with equal authority.** A documentation pair is three sibling files: English `foo.md`, Chinese `foo.zh.md`, and a consistency record `foo.i18n.yaml`. Neither language is canonical — a document may be authored and reviewed Chinese-first and translated to English afterwards, or the reverse; what binds the pair is that both sides must say the same thing, and pairs merge whole (both languages plus the record, never one alone). Policy: [docs/i18n/README.md](../../../../docs/i18n/README.md); translation rules: [docs/i18n/translation-rules.md](../../../../docs/i18n/translation-rules.md); terminology source of truth: [docs/i18n/terminology.md](../../../../docs/i18n/terminology.md).
 - **A sidecar record of both blob hashes makes consistency checkable.** `foo.i18n.yaml` holds the full git blob hash of each side as of the last confirmed-consistent state. An edit to either side without re-confirming the pair is then mechanically detectable as a pure content comparison — no history lookup — and the hashes are computable for files edited in the same PR, which a commit-hash record is not. Re-recording (`verify-translation-pairing --write <pair>`, which requires naming the confirmed pairs — bulk re-record is an explicit `--write --all`) produces a reviewable yaml diff: confirming consistency is an explicit, visible act in the PR.
-- **`verify-translation-pairing` joins `doc-sync`.** The gate ([scripts/verify-translation-pairing.ts](../../../../scripts/verify-translation-pairing.ts)) enforces: every discovered, non-excluded source has a complete pair; every existing pair is complete (all three files) and consistent (both hashes match, the Chinese side and every authored English source carry their switchers while listed generated English sources are exempt, structural signatures identical); and excluded generated, instruction, or bilingual-by-construction files stay unpaired. Relative document links whose targets belong to that active corpus use the target sibling matching the source locale, while the structure signature normalizes `.md` and `.zh.md` siblings to one semantic target and retains the exact query/fragment suffix; the [localized bilingual links decision](2026-08-18-localized-bilingual-links.md) owns that refinement. [scripts/translation-pairing.manifest.json](../../../../scripts/translation-pairing.manifest.json) contains only explicit exclusions, so no requirement can bypass discovery and receive a weaker check. Source-oriented code gates consume a `.zh.md` fence sequence as a derivative only when its unsuffixed sibling has the same tracked fences in the same order with byte-identical bodies; an incomplete, reordered, reclassified, or changed sequence stays independent, so the owning code gate or pairing gate reports the mismatch.

 - **One corpus-wide requirement.** Every document in scope requires a complete pair from creation; the policy has no per-file rollout state, date cutoff, or README-specific class. Repository-root policy documents are named explicitly: `CONTRIBUTING.md`, `BRAND_GUIDELINES.md`, and `SAFETY.md` participate in the same discovery and pairing rules even though they are outside documentation directories. README discovery covers every case-insensitive README basename outside vendored, dependency, and ignored build-output trees, including future top-level directories. A site-published pair uses `pairedPages()` so the root locale projects `.zh.md` and `/en/` projects `.md`; creating a counterpart alone does not publish it.
 - **Pairing records are metadata, not Cordis Loader configuration.** Cordis configuration discovery accepts actual `.cordis.yml` and `.cordis.yaml` files while excluding `*.i18n.yaml`, even when the document name contains `cordis`. This preserves validation of executable Loader entries without parsing translation hashes as configuration.
-- **Translation is agent work with human review.** Routine changes use the direct one-pass path owned by the [lightweight-translation decision](2026-08-08-lightweight-routine-documentation-translation.md). The [extended translation skill](../../../skills/dsh-translate-docs/SKILL.md) retains delegated translation and the other heavier mechanisms for explicit user invocation; both paths defer to the documentation contracts as their sources of truth.

 - When the two sides disagree, no mechanical rule picks a winner — the PR review does. That is the price of equal authority, accepted deliberately: the alternative (a canonical language) forbids Chinese-first authoring.
 - Generated English documents remain derived from source and freshness-gated by their owning generators. A generated page with a reviewed Chinese counterpart participates in the three-file pairing workflow, with one structural exception: the generated English source has no language switcher because adding one would make the generator stale, while the Chinese counterpart links back to it. Generated pages without a reviewed counterpart remain explicit exclusions and use an English website projection.
 - The exclusions-only manifest makes every current and future in-scope document mandatory through the same path. There is no explicit requirement, cutoff, or class entry that can fall outside discovery while appearing enforced.

 ## Problem
 
-The harness hand-rolls a lot of infrastructure that mature external packages already provide. Some of that is deliberate — vendored Cordis ([vendoring decision](2026-06-11-vendor-cordis-as-source.md)), the [twin LLM adapters](../architecture/2026-06-13-twin-llm-adapters.md), schemastery as the config-schema standard — but much of it accreted from an unstated "avoid new dependencies" reflex: the repo-wide external dependency list stayed tiny while packages grew their own SSE parsers, protocol framers, retry loops, and glob matchers. Nothing in `AGENTS.md` actually stated a dependency policy, so agents inferred one from the existing pattern, and the inferred rule ("don't add deps") is stricter than anyone decided. That is the "Not Invented Here" fallacy operating by default: every hand-rolled clone of a well-maintained library is code we test, document, review, and debug ourselves, with none of the ecosystem's accumulated edge-case fixes.

 - **Keep the implicit no-new-deps culture.** Rejected: it was never a recorded decision, and its cost is concrete — hand-rolled protocol and parsing code duplicates battle-tested libraries, inflates the per-file coverage burden, and slows every reviewer who must re-derive edge cases the ecosystem already fixed.
 - **A hard allowlist of approved packages.** Rejected: the repo is pre-release and the dependency set is small; a per-PR evidence bar (net deletion, health, fit) plus review keeps judgment where the context is, without a standing committee artifact that would itself need maintenance.
-- **Vendor every new dependency like Cordis.** Rejected: vendoring is for packages we must patch or pin against upstream churn ([vendoring decision](2026-06-11-vendor-cordis-as-source.md)); applying it broadly recreates the maintenance burden the dependency was meant to shed. Ordinary npm dependencies with lockfile pinning are the default.

 - **维持隐性的「不加新依赖」文化。** 不予采纳：它从来不是一项有记录的决策，而其成本是具体的——手写的协议与解析代码重复实现了久经实战检验的库，推高了按文件计的覆盖率负担，还拖慢每一位评审人：他们必须重新推导生态早已修复的边界情况。
 - **一份获批包的硬性白名单。** 不予采纳：仓库处于预发布阶段，依赖集合很小；按 PR（Pull Request）设置证据门槛（净删除、健康度、契合度）再加评审，就能把判断留在上下文所在之处，无需一份本身也需要维护的常设委员会式产物。

Concurrent installs are serialized and repeated installation is idempotent, while the jobs and latency boundary owned by [Fast local Git hooks](../../archived/process/2026-07-22-fast-local-git-hooks.md) stay unchanged.
 
 The repository becomes a Git format-1 repository after the first installation. The installer requires Git 2.26 for `--show-scope`; the worktree-config extension itself predates that command. Custom worktree hook managers require an explicit integration choice; inherited hook paths can coexist across other worktrees, but opting the current worktree into Lefthook means those inherited hooks do not run there unless the contributor chains them through `lefthook.yml`.

 "Land the stack" merges the complete official stack through `gh stack merge <stack-number> --yes --merge`. A partial landing requires an explicit boundary PR and merges the bottom prefix through that PR. The workflow never falls back to per-PR `gh pr merge` and manual retargeting. A direct native merge is all-or-nothing; a merge queue may process the selected PRs in separate groups, so every selected PR must independently reach `MERGED` before the landing is complete.

 Relevant checks normally run before publication. `gh stack sync` is the explicit exception because it fetches, cascade-rebases, and pushes as one operation: every rewritten layer is validated immediately afterward, and no affected PR merges until that evidence passes. After any rewritten push, current heads, unresolved review threads, approvals, mergeability, and checks are re-audited because earlier commit OIDs and inline anchors may be outdated.

 ### Versions land in the repository from a local command; CI only checks and uploads
 
 Each sequence has one bump-and-commit command: it derives the target version, writes it into the relevant manifests, runs `pnpm install --lockfile-only`, and commits the manifests with the lockfile. The published version is therefore readable from the repository. A human creates the tag after the commit merges to master; CI never writes to the repository and needs no write permission.

Private packages receive no release tag and remain outside pack and publish; they follow the version because [the static version-coherence gate](2026-09-03-workspace-version-coherence-gate.md) requires every dsh package's version to equal the root's. The root check accepts a prerelease segment, so explicit versions such as `0.0.1-alpha.1`, `0.0.1-canary.1`, and `0.0.1-rc.1` drive the same pack, installed-artifact probe, and publication path. `dsh` publication maps `alpha` and `canary` to their matching npm dist-tags, maps other prereleases including `rc` to `next`, and leaves stable versions to npm's `latest` default. Other release families retain their own dist-tag policy.

 ### 版本由本地命令写进仓库，CI 只核对与上传
 
 每条序列有一条 bump-and-commit 命令：算出目标版本，写进相关 manifest，跑 `pnpm install --lockfile-only`，再把 manifest 连 lockfile 一起 commit。发布版本因此在仓库里查得到。tag 由人工在 commit 合入 master 后打；CI 不写仓库，也不需要写权限。

-The ordinary `pnpm run test:coverage` command remains one Vitest invocation. Linux coverage CI fixes `DSH_COVERAGE_PARTITIONS=4`; native Windows now also fixes it at 4 to reduce process-creation pressure under high self-hosted concurrency. No elapsed-time trigger changes either count while a run is in progress.

+The ordinary `pnpm run test:coverage` command remains one Vitest invocation. Linux coverage CI fixes `DSH_COVERAGE_PARTITIONS=4`; native Windows now also fixes it at 4 to reduce process-creation pressure under high self-hosted concurrency. No elapsed-time trigger changes either count while a run is in progress. The [coverage-exempt heavy suite](../../archived/process/2026-07-31-coverage-exempt-heavy-suites.md) remains a separate uninstrumented gate beside the instrumented work.
 
 When partitioning is enabled, `scripts/run-gates.ts` selects `pnpm run test:coverage:partitioned` for the instrumented gate. `scripts/coverage-partitions.ts` starts the configured Vitest children concurrently, each with one worker. The coordinator collects the instrumented inventory from a `vitest list --filesOnly` run (caller filters narrow it; exempt heavy suites are removed because list does not apply their exclusion), reads recorded per-file durations from a coordinator-persisted gitignored file (restored and saved through the GitHub cache on the windows-coverage job, because checkout removes it and Vitest's own cache never survives CI), and assigns files to partitions by longest-processing-time by way of a min-heap, so the heavy subprocess-bound suites spread across children instead of piling into whichever shard a path hash lands them in. Each partition receives a temporary Vitest config whose include is its file list per project (command-line files exceeded the Windows CreateProcess limit; the mutually exclusive thread-safe and process-bound projects keep only their own files so nothing runs twice), an empty partition is rejected before any child starts, the heaviest partition starts first so its verdict lands earliest (fail-fast), and the duration history is restored and saved through the GitHub cache with per-run keys (cache entries are immutable). Partition mode suppresses thresholds and coverage reporters in each child, gives every child a separate report directory, and writes one blob report per process.

 ## 决策
 
-普通的 `pnpm run test:coverage` 命令仍只启动一次 Vitest。Linux 覆盖率 CI 将 `DSH_COVERAGE_PARTITIONS` 固定为 4；原生 Windows 现在也固定为 4，以降低自托管高并发下的进程创建压力。运行期间不会由任何耗时触发器改变这两个数量。[覆盖率豁免重型套件](2026-07-31-coverage-exempt-heavy-suites.zh.md)仍作为独立的无插桩门禁与插桩工作并排运行。

 启用分区后，`scripts/run-gates.ts` 为插桩门禁选择 `pnpm run test:coverage:partitioned`。`scripts/coverage-partitions.ts` 按配置数量并发启动 Vitest 子进程，每个进程只用 1 个 worker。协调器通过 `vitest list --filesOnly` 收集插桩清单（调用方过滤器会先收窄清单；exempt 重型套件需在此剔除，因为 list 不应用其排除），从协调器持久化的 gitignore 文件读取逐文件耗时（windows-coverage job 通过 GitHub cache 恢复并保存该文件，因为 checkout 会删除它且 Vitest 自身缓存无法在 CI 存活），并借最小堆按最长处理时间把文件分配到各分区，使重量级子进程密集型套件分散到不同子进程，而不是全部落入路径 hash 恰好命中的那一个分片。每个分区获得一个临时 Vitest 配置，其 include 按 project 拆分（命令行传文件会超过 Windows CreateProcess 上限；互斥的 thread-safe 与 process-bound project 只保留各自的文件，避免任何文件跑两次）；空分区会在任何子进程启动前被拒绝，最重的分区最先启动使其结论最早落地（fail-fast），耗时历史通过 GitHub cache 以每 run 唯一键恢复与保存（cache 条目不可变）。分区模式会在各子进程中关闭阈值与覆盖率报告器，为每个子进程分配独立报告目录，并让每个进程写出 1 份 blob 报告。

 This is a *text-storage* seam, deliberately half a level above byte-level fsspec (`cat`/`open` hand back raw bytes). UTF-8 decoding, binary/NUL rejection, guarded full-file writes, and guarded literal text edits live in the provider so the policy layer never touches raw bytes, reimplements cross-chunk decoding, or separates stale checks from the mutation critical section. Model-facing concepts still stay out of the provider: no line windows, numbered lines, rendered footers, or observed-state store leak down.

 - Text reads no longer return backend-numbered line records or `full`/`partial` views; authorization is based on version freshness, so a windowed read can authorize edit when the file is unchanged.

 ## Consequences
 
 - No composition text and no path crosses the browser wire in either authoring direction; the `entryListSchema`/`!!js` concern dissolves with `assertComposition` itself (deleted). The authoring operations are `read`/`copy`/`openDocument`/`remove` — none accepts a filesystem target, and Connection authenticates them with the complete Host API.
-- With the editor gone, hand-editing `agent.cordis.yml` is the ONLY composition edit, so the standing-mount layer grew stamp-keyed generations: `ensureStanding` compares the file's mtime+size and starts the next generation for later sessions ([standing-mounts note](../architecture/2026-08-08-per-preset-standing-mounts.md), updated in place). Without this, an edited file would serve stale compositions until process restart.

Without this, an edited file would serve stale compositions until process restart.
 - A copy is a full snapshot that drifts from an upgraded shipped source — accepted; the preset layer has no patch semantics (that is the bundle layer's `cordis.patch.yml`), and the shipped set itself pays the same cost (`cordis`/`code` are full copies of `standard`) for one-file readability.
 - `read` dropped `writable` (no editor to gate) and builtin directories are never opened (`openDocument` refuses non-`user` trust like `remove`): the install is overwritten by upgrades, and pointing an editor into it invites edits an upgrade silently discards.

 ## 后果
 
 - 创作两个方向都没有组装文本或路径跨越浏览器传输层；`entryListSchema`/`!!js` 的顾虑随 `assertComposition` 本身（已删除）一并消解。创作操作是 `read`/`copy`/`openDocument`/`remove`——没有一个接收文件系统目标，且 Connection 用完整 Host API 的同一会话认证它们。
-- 编辑器移除后，手改 `agent.cordis.yml` 成为唯一的组装编辑方式，因此常驻挂载层增加了以 stamp 为键的代际：`ensureStanding` 比对文件的 mtime+大小，为后续会话开启下一代际（[常驻挂载 note](../architecture/2026-08-08-per-preset-standing-mounts.zh.md)，已就地更新）。没有它，改过的文件要等进程重启才生效。

 - 副本是完整快照，会随随附来源升级而漂移——接受；preset 层没有 patch 语义（那是 bundle 层 `cordis.patch.yml` 的能力），随附集合自己也为「一个文件读完整份组装」付了同样的代价（`cordis`/`code` 就是 `standard` 的完整副本）。
 - `read` 去掉了 `writable`（没有编辑器可门控），内置目录绝不被打开（`openDocument` 与 `remove` 一样拒绝非 `user` 信任）：安装目录会被升级覆盖，把编辑器指向它等于招揽会被升级悄悄丢弃的编辑。

-A recorded-session snapshot starts a shipped profile through `dsh`, drives its public interface, and compares normalized output with committed expected outputs. ACP-owned scenarios additionally drive the stdio protocol and compare its transcript. A session log recorded once from the real API supplies all later model streams.

 The [session-log snapshot corpus decision](2026-08-24-session-log-snapshot-corpus.md) supersedes this note's ACP-specific placement and controller ownership. This note remains the rationale authority for session-log fixtures, replay derivation, exceptional overrides, normalization, and ACP transcript comparison.

 ### Coverage contract
 
-The lane covers three behavior families. Live-turn scenarios pin ordinary tool execution, cancellation, non-retryable failure, transient retry, resident questions, and mid-turn steering; synchronization uses durable events, `whenIdle()`, or an explicit replay marker rather than delays. Cold-history scenarios seed through the real persistence API and cover history rendering, sidebar search, trajectory and waterfall views, and tool details without model calls. Browser-lifecycle scenarios cover first-send workspace materialization, reload recovery, layout reset, theme and locale preferences, and workspace create/rename/view operations. Each family asserts the browser surface and the authoritative host state; a stray model call or under-consumed fixture fails teardown. The required lane additionally carries an 88-turn synthetic Chat scroll contract mixing wrapped Markdown, fenced code, and paired bash calls/results. Real wheel, composer, tool, tab, session, and viewport interactions assert a named settled row's top relative to the transcript scrollport and distance from the true bottom across concurrent history prepend plus paced streaming, pinned/away streaming, tool-disclosure offscreen cycles, expanded-history view/session remount, width reflow, immediate pinned remount, composer resize, and textarea wheel chaining; real keyboard paging and a touch-style fling emulation additionally pin wheel-free bottom-follow ownership ([reader-scroll-attribution note](../bug-fix/2026-08-06-reader-scroll-attribution-observed-top-ledger.md)); it deliberately pins neither DOM cardinality nor absolute `scrollTop`, so the same contract can qualify a virtualized implementation. A separate interaction contract over the same fixture pins heterogeneous-row order, independent adjacent tool disclosure, exact user-message clipboard content, a turn-bounded message fork, source/child isolation, and a real follow-up turn in the child; wheel input only navigates to semantic targets and carries no geometry expectation. A short live-history contract starts from a blank workspace and drives consecutive composer turns, including real bash call/result rounds and a paced long final response, pinning one session identity, exact per-turn event ownership, browser echo uniqueness, and composer recovery without timing thresholds.

 ### CI stance
 
-The lane is a required compare-only gate for Linux pull requests under the [browser snapshot CI decision](2026-07-30-web-browser-snapshot-ci-gate.md). The `node 24 / snapshots and artifacts` consumer job owns the [single Linux build](../process/2026-07-30-independent-ci-consumer-build.md), installs the lockfile-selected Chromium, restores its OS-and-lockfile-keyed cache, and runs the lane with `DSH_SNAPSHOT=replay`. This is an intentional plane split: the host and specs use the [tsx source-launch contract](../architecture/2026-07-29-dsh-source-launch-tsx-esm.md), while the browser consumes `apps/web/dist` and package `lib/client.js` artifacts, so the gate depends on `built-package-invariants` for those client artifacts. The self-hosted default-branch Linux serial standby runs the same gate; there is no hosted Linux serial producer of the browser cache consumed by pull requests, and the persistent self-hosted pool needs no hosted cache. CI never records or refreshes goldens. Scenarios remain POSIX-oriented and stay outside the Windows and macOS matrices.

 High-cardinality performance diagnostics use the separate opt-in `apps/web/tests/**/*.perf.ts` inventory selected only by `vitest.web.perf.config.ts`. The isolated `complex-history.perf.ts` cases reuse the real scaffold: the workspace case seeds 1,000 compact sessions plus one 500-turn history containing 500 tool calls, exhausts and remounts that history in Chat, and reports Chromium main-thread, DOM, listener, heap, paging, search, and Trajectory measurements. Two continuation cases seed the same long history but compare the default 24-turn Chat window with all 500 turns expanded before each continues eight identical turns through the real composer, agent loop, SSE wire, tools, and persistence; two turns execute a real `bash` call and assert its durable result, while the final turn fills an 8,232-character mixed-language prompt and replays 120 paced text deltas. A separate soak case starts from a blank session, drives 100 consecutive real composer turns with a `bash` call and result every tenth turn, forces GC every ten turns, and reports ten-turn latency windows plus retained browser state. It then submits a 101st text-only turn with a trusted browser click and measures browser-clock send-to-transcript-DOM and send-to-post-paint latency, excluding the composer's draft mirrors, separately from full-turn completion. Per-turn diagnostics cover composer fill, click-to-user-echo, click-to-first-chunk, completion, browser mutations, persisted chunks, and tool events; the synthetic replay model has enough context capacity to keep fixture cardinality stable instead of consuming scripted calls through compaction. Structural assertions pin the intended load, stream, and tool shapes, but timing remains threshold-free because machine speed is not a correctness contract. The required `vitest.web.config.ts` inventory remains limited to `*.e2e.ts` and `*.snapshot.ts`, so neither `test:web:built` nor its CI gate collects performance cases.

 高基数性能诊断使用单独按需启用的 `apps/web/tests/**/*.perf.ts` 清单，并且只由 `vitest.web.perf.config.ts` 选中。`complex-history.perf.ts` 的隔离用例复用真实 scaffold：工作区用例播种 1,000 个紧凑会话以及一份包含 500 次工具调用的 500 轮次历史，在 Chat 中穷尽并重新挂载该历史，并报告 Chromium 主线程、DOM、监听器、堆内存、分页、搜索和 Trajectory 测量结果。两个续聊用例播种同一份长历史，但比较默认的 24 轮次 Chat 窗口与展开全部 500 轮次的状态，然后各自通过真实输入框、agent loop、SSE wire、工具和持久化继续进行 8 个相同轮次；其中两轮执行真实 `bash` 调用并断言其持久化结果，最后一轮则填入一条包含 8,232 个字符的混合语言提示词，并回放 120 个带节奏的文本增量。一个单独的 soak 用例从空白会话开始，通过真实输入框连续驱动 100 轮，每第 10 轮执行一次 `bash` 调用并产生结果，每 10 轮强制执行一次 GC，并报告每 10 轮的延迟窗口及保留的浏览器状态。随后它通过受信任的浏览器点击提交第 101 个纯文本轮次，并使用浏览器时钟分别测量发送到 transcript DOM 和发送到绘制后的延迟，排除输入框的草稿镜像，并与完整轮次完成时间分开。逐轮诊断涵盖输入框填入、点击到用户消息回显、点击到首个分片、完成、浏览器变更、持久化分片和工具事件；合成回放模型拥有足够的上下文容量，可使 fixture 基数保持稳定，而不会因压缩（compaction）消耗脚本化调用。结构性断言钉住预期的负载、流和工具形状，但时间仍不设阈值，因为机器速度不属于正确性约定。必需的 `vitest.web.config.ts` 清单仍仅限 `*.e2e.ts` 和 `*.snapshot.ts`，因此 `test:web:built` 及其 CI 门禁都不会收集性能用例。

 For Linux PRs, the `node 24 / snapshots and artifacts` job must run the full web browser replay/compare suite. When `DSH_WEB_SNAPSHOT_WORKERS` is configured, `scripts/run-gates.ts` registers `test:web:ci` as the `ci-consumers` gate and explicitly injects `DSH_SNAPSHOT=replay`; CI never runs in `record` or `refresh` mode, so when the committed goldens disagree with the currently assembled application, the tests fail directly instead of silently rewriting them on the runner and then passing.
 
-The consumer job owns the [single Linux build](../process/2026-07-30-independent-ci-consumer-build.md), so `apps/web/dist` and the package `lib/` directories remain in its workspace for the browser suite. On hosted runners, CI installs Chromium and its system dependencies at the Playwright version in the lockfile.

 Local `pnpm run test:web` continues to build first and then run the full browser suite serially; `test:web:built` is the serial entry point for existing build artifacts. Developers explicitly run `DSH_SNAPSHOT=refresh pnpm run test:web` only after confirming that user-visible output changed intentionally, review every expected-output diff, and then verify again in replay mode that no files are written.

A unit may remain host-only by omitting `wire`. How a client value is *rendered* is the slot system's business, never the projection layer's. The state/view split is specified by the [implemented state and client-view note](../../archived/architecture/2026-08-19-session-projection-state-and-client-views.md).
 - **The host is the only place a projection is computed.** The framework drives every registered unit forward eagerly: each committed session event passes through `apply`; a unit uninterested in an event returns the same state reference, and an unchanged reference (`Object.is`) produces no downstream work. Clients never fold domain events — they receive finished values (baseline block + push frame below). This removes the double-implementation trap (plan's two-event fold written once, on the host) and any client-side domain code.
 - **State is always computed, never logged.** The log holds events only; the unit's state lives in the framework's per-session watermark cache (`{state, observedSeq}` per unit) and, in a later phase, in a **persisted projection cache** on the domain-KV storage seam: rows of `(sessionId, key, ver, seq, val)` (`ver` = the unit's `stateVersion`, `seq` = the watermark, `val` = the state JSON). A row is never wrong, only possibly stale — its `seq` says exactly how stale. The one read recipe, cold and live alike: take the cached state (or `init()`), forward-apply only the events past its watermark, `view` the result. Cold listings (every session's title across all workspaces) become an index read plus, at worst, a short tail replay; the session-persistence seam grows a read-from-seq primitive for that tail in the same later phase. Write policy: throttled (count/interval, configurable) plus two mandatory points — `turn/end` and detach (the live-to-cold moment). A crash between writes costs a longer tail replay, never a wrong value.
 - A domain's input event set is its own choice: todos folds `todo/write` alone; plan folds `plan/mode` plus its own `/plan` `command/run` records (see the plan section); goal folds `goal/change` metadata; session title folds its title events (retiring the bespoke `session/title` frame and the client's title-snapshot map — the fourth hand-rolled projection this seam absorbs).

 - **host 是投影唯一的计算地点。** 框架主动驱动（eager drive）每个已注册的单元：每个已提交的会话事件都经过 `apply`；对某事件不感兴趣的单元返回同一个状态引用，而引用未变（`Object.is`）就不产生任何下游工作。客户端从不折叠领域事件——它们收到的是成品值（基线块 + 下文的推送帧）。这消除了双重实现陷阱（plan 的双事件折叠只在 host 写一遍），也消除了一切客户端侧领域代码。
 - **状态永远靠计算得出，绝不入日志。** 日志只存事件；单元的状态住在框架的按会话水位线缓存里（每单元一份 `{state, observedSeq}`），并在后续阶段进入 domain-KV 存储 seam 上的**持久投影缓存（persisted projection cache）**：形如 `(sessionId, key, ver, seq, val)` 的行（`ver` = 单元的 `stateVersion`，`seq` = 水位线，`val` = 状态 JSON）。一行永远不会是错的，至多是陈旧的——其 `seq` 精确说明陈旧到哪。冷读与活读共用同一套读取配方：取缓存状态（或 `init()`），只对超出其水位线的事件做正向 `apply`，再对结果做 `view`。冷列表（跨全部 workspace 列出每个会话的标题）变成一次索引读，至多外加一小段尾部回放；session-persistence seam 在同一后续阶段为这段尾部补一个按 seq 起读的原语。写入策略：节流（次数/间隔，可配置）外加两个强制点——`turn/end` 与 detach（由活转冷的时刻）。两次写入之间崩溃的代价是尾部回放更长一些，绝不会是值出错。
 - 领域的输入事件集由领域自己选择：todos 只折叠 `todo/write`；plan 折叠 `plan/mode` 外加它自己的 `/plan` `command/run` 记录（见 plan 一节）；goal 折叠 `goal/change` 元数据；会话标题折叠其标题事件（顺带下线专设的 `session/title` 帧与客户端的标题快照表——这是该 seam 收编的第四个手工投影）。

 **Where the files actually live (root mismatch closed; resolve-once residual still open).** The shared base defaults the session store to the global harness home (`$DSH_HOME/sessions`, default `~/.dsh/sessions`), while the shipped Web overlay used to give the json backend the relative root `./.storages`: `workspace.json` and `session_projcache.json` landed under `<launch dir>/.storages/` — two launches from different directories shared their sessions yet saw different workspace registries and different projection caches, and the cache exists precisely to serve the cross-session cold listing, which missed for every session last cached under another launch directory. That mismatch is now closed: the overlay anchors `storage-json.root` to `$DSH_HOME/storages` with the same `!!js` expression the session root uses (`apps/cli/config/web.cordis.yml`). The residual hazard: `JsonStorageBackend` still never resolves its root — each unit open joins the path against whatever `process.cwd()` is at that moment (packages/storage/storage-json/src/index.ts); the shipped overlay root is already absolute and unaffected, but any relative root (bare Loader boots, tests) still splits on a later cwd change — the exact hazard the JSONL session backend resolves-once to prevent ("later process.cwd() changes cannot split one backend across roots", packages/session/session-persistence-jsonl/src/index.ts).
 
-**Recovery behavior.** Inside a healthy medium the cache is fully self-healing by design: a `stateVersion`-mismatched row is discarded and refolded, a log shrunk below a row's watermark is detected by the anchored restore floor and answered with one full re-read, and every background write is fail-soft. But at the *medium* level there is no recovery at all: a truncated, hand-edited, or version-bumped `session_projcache.json` fails `openJsonUnit` with `malformed-medium`/`version-mismatch` (packages/storage/storage-json/src/format.ts), a schema-drifted record fails domain open with `invalid-record` (packages/storage/storage-domain/src/index.ts), the rejection propagates through `SessionProjectionCache[Service.init]`, and under the CLI's fail-loud boot the assembly refuses to start. A file whose entire content is rebuildable from session logs can brick boot. This contradicts the cache package's own stated stance ("a stale or unreadable cache costs a longer tail replay, never a wrong value") and the cache domain spec's JSDoc ("version bumps discard the whole medium"), which describes an aspiration, not the implementation. Partially superseded for the projection cache: [the per-session cache files note](../../implemented/architecture/2026-08-19-projection-cache-per-session-files.md) removed the global `session_projcache` domain, so the cache half of this proposal (recovery on that domain) no longer applies; the `workspace.json` half remains current. The `invalid-record` class for the per-record projection cache is now also superseded: the shipped domain declares `invalidRecords: 'backup-and-skip'` ([cross-version read-compat note](../../implemented/architecture/2026-09-02-projcache-cross-version-read-compat.md)), which backs the failing record up and skips it at open, so the reset/destroy proposal below stays relevant only for whole-medium damage on authoritative or single-document media.

 A cold (persisted, unattached) session has no authoritative stored answer to "when did the user last prompt here". `dsh-host-apiproxy` serves `updatedAt` from the optional projection cache's `lastPromptAt`, falling back to `createdAt`, and the Web client sorts its Session tree by that value. The cache is fail-soft and checkpointed asynchronously, so a missing or delayed row makes a recently prompted Session sort too old.

 The phase vocabulary belongs to the declaring slot, not to the slot framework globally. `SlotMap` carries the exact phase tuple for compile-time registration, and the runtime `SlotSpec` repeats that tuple as the sorting authority. Other chains acquire no composer terminology and need no migration unless they deliberately declare phases.

-The [package hierarchy](../../archived/architecture/2026-06-20-package-hierarchy.md) already removed several of these by hand: `scripts/publint-all.ts` now derives its list from the `packages/<group>/<pkg>` layout, and the two `tsconfig` `paths` maps collapsed to one `@deepseek-ai/dsh-*` wildcard — since reverted to one explicit alias per package, generated and gated, because resolving a wildcard's candidates in order dominated source-launch boot ([explicit workspace path aliases](../../implemented/process/2026-08-27-explicit-workspace-path-aliases.md)). What remains is the inventory that cannot be globbed away — chiefly the aggregate configs' (`tsconfig.host.json`, `tsconfig.client.json`) project `references`, which TypeScript requires as explicit arrays (no wildcard form).

 Static lists are appropriate when they encode policy; they are needless friction when they duplicate manifest data or layout facts that already exist in `package.json`, workspace globs, or the package hierarchy.

 包与门禁清单在 TypeScript project references、包文档和 CI 描述中反复出现。大多数只是重述包布局、manifest（元数据清单）数据或聚合命令内容。因此每新增一个包都会产生本可避免的同步点。
 
-[包层级结构](../../archived/architecture/2026-06-20-package-hierarchy.md)已经手动消除了其中若干：`scripts/publint-all.ts` 现在从 `packages/<group>/<pkg>` 布局推导列表，两份 `tsconfig` 的 `paths` 映射也合并为一个 `@deepseek-ai/dsh-*` 通配符——该合并此后已被回退为「每包一条、由生成器托管并有门禁把关」的显式别名，因为按顺序试候选的解析开销主导了源码启动时间（[显式 workspace 路径别名](../../implemented/process/2026-08-27-explicit-workspace-path-aliases.zh.md)）。剩下的是无法用 glob 消除的清单，主要是聚合配置（`tsconfig.host.json`、`tsconfig.client.json`）中的项目引用（`references`）——TypeScript 要求它们是显式数组（没有通配符形式）。

 当静态列表编码的是策略时，它们是合理的；当它们只是重复 `package.json`、workspace glob 或包层级结构中已有的 manifest 数据或布局事实时，就是不必要的摩擦。

 The budget policy has the same split. [docs/AGENTS.md](../../../../docs/AGENTS.md#wordcount-budgets) states a 1,800-word target and 5% headroom for `architecture.md`, but the [budget manifest](../../../../scripts/doc-budgets.manifest.json) allows 2,400 words while the file contains 1,313. The budget gate passes because it checks the manifest ceiling, not the target or ratchet rule. High-impact prose therefore needs a named source or a focused check that consumes the source; a second hand-written copy is not a freshness mechanism.

 预算策略也存在相同的分裂。[docs/AGENTS.md](../../../../docs/AGENTS.md#wordcount-budgets)为 `architecture.md` 规定 1,800 词目标和 5% 余量，但[预算 manifest（元数据清单）](../../../../scripts/doc-budgets.manifest.json)允许 2,400 词，而该文件实际包含 1,313 词。预算门禁之所以通过，是因为它只检查 manifest 上限，不检查目标或棘轮规则。因此，高影响正文需要一个具名真源或消费真源的聚焦检查；第二份手写副本不是新鲜度机制。

 ### Slot declarations are first-class injectable waits
 
-`SlotRegistry.inject()` now waits on the typed ledger key directly; it does not bridge declarations into synthetic `slot:<name>` Cordis services. The callback follows declaration collapse and redeclaration while its controller remains owned by the contributing plugin fiber, and direct registration into an undeclared slot still fails loud. This removes the stale-disposer presence machine and the typo-prone parallel service namespace. The complete lifecycle and failure contract lives in the [slot declaration injection decision](../../implemented/architecture/2026-08-05-slot-declaration-injection.md).

-# Agent Note: Drop bash full-output spill files
-
-Status: rejected — full-output recovery is a real bash behavior. A future artifact/blob service may generalize it, but dropping spill files before that replacement would lose useful command output.
-
-English | [中文](2026-06-20-drop-bash-output-spill-files.zh.md)
-
-## Problem
-
-`dsh-bash-local` keeps bounded in-memory output and spills large stdout/stderr streams into private temp files. That requires a private directory, random owner-only file creation, close-failure handling, byte-offset incremental reads, lossy read reporting, path rendering in model-facing text, and cleanup discipline. The tool then tells the model to read a local spill path when output was truncated.
-
-This solves a real problem, but in a narrow and leaky way. A spill path is a process-local filesystem artifact exposed to model output, not a durable harness artifact with scoped access, retention, or UI affordances. It also complicates background-job reads because a lossy incremental read has to point at one or two spill files.
-
-## Proposal
-
-Keep tail truncation, drop full-output spill files. A bash result contains the bounded tail plus a clear truncation marker; no path is emitted. If users need full-output recovery, add a generic artifact/blob service with explicit ownership, cleanup, and UI rendering, then let bash attach large outputs to that service.
-
-This proposal can land independently of [a generic long-running tool runtime](../../implemented/architecture/2026-06-20-generic-long-running-tool-runtime.md). If background jobs stay, `bash_output` should still report that output was dropped, but without advertising a spill path.
-
-## Acceptance criteria
-
-- `CollectedOutput` no longer carries spill paths.
-- `OutputCollector` keeps bounded buffers only and deletes the temp-file machinery.
-- `renderResult()` reports truncation without a filesystem path.
-- Tests cover tail truncation and no longer assert full-output file contents.
-- Security guidance in [docs/defensive-patterns.md](../../../../docs/defensive-patterns.md) stops treating private spill files as a model-visible interface.
-
-## What we give up
-
-A model or user cannot recover the omitted prefix of a huge command output from a temp file. That is acceptable until there is a real artifact service. The current spill path is too much bespoke machinery for a feature whose lifecycle and permissions are not designed.

-# Agent Note: 移除 bash 完整输出 spill 文件
-
-Status: rejected — 完整输出恢复是真实的 bash 行为。未来的产物／blob 服务或许能将其泛化，但在替代方案就位前删除 spill 文件会丢失有用的命令输出。
-
-[English](2026-06-20-drop-bash-output-spill-files.md) | 中文
-
-## 问题
-
-`dsh-bash-local` 在内存中保留有界的输出，并将大体量的 stdout/stderr 流写入私有临时 spill 文件。这要求一个私有目录、随机创建仅所有者可访问的文件、关闭失败处理、基于字节偏移的增量读取、有损读取报告、在面向模型的文本中渲染路径，以及清理纪律。当输出被截断时，该工具会告知模型去读取一个本地 spill 路径。
-
-这解决了一个真实问题，但方式狭隘且有泄漏。spill 路径是一项暴露给模型的进程本地文件系统产物，而非具有作用域访问控制、保留策略或 UI 支持的持久化 harness 产物。它还使后台任务的读取变得复杂，因为有损增量读取必须指向一个或两个 spill 文件。
-
-## 提案
-
-保留尾部截断，移除完整输出 spill 文件。bash 结果包含有界的尾部内容加一个明确的截断标记；不输出路径。如果用户需要恢复完整输出，则添加一个通用的产物／blob 服务（具有明确的所有权、清理和 UI 渲染），然后让 bash 将大体量输出附加到该服务。
-
-本提案可以独立于[通用长时间运行工具运行时](../../implemented/architecture/2026-06-20-generic-long-running-tool-runtime.zh.md)落地。如果后台任务保留，`bash_output` 仍应报告输出已被丢弃，但不再提供 spill 路径。
-
-## 验收标准
-
-- `CollectedOutput` 不再携带 spill 路径。
-- `OutputCollector` 仅保留有界缓冲区，删除临时文件机制。
-- `renderResult()` 报告截断时不包含文件系统路径。
-- 测试覆盖尾部截断，不再断言完整输出文件的内容。
-- [docs/defensive-patterns.md](../../../../docs/defensive-patterns.zh.md) 中的安全指导不再将私有 spill 文件视为面向模型的接口。
-
-## 放弃的能力
-
-模型或用户无法再从临时文件恢复大体量命令输出中被省略的前缀。在真正的产物服务出现之前，这是可以接受的。当前的 spill 路径为一个生命周期和权限均未经设计的功能引入了过多的专用机制。

-# Agent Note: Collapse workflows to the exercised foreground core
-
-Status: rejected — Workflow progress is an intentional observation API; make it useful through a consumer instead of deleting it.
-
-English | [中文](2026-07-12-collapse-workflow-to-foreground-core.zh.md)
-
-## Problem
-
-The workflow capability executes foreground JavaScript that composes subagents, but it also carries an unconsumed progress-observation system. No production listener subscribes to any of the six `workflow/*` events; listeners exist only in workflow tests. Nevertheless the seam defines run/phase/agent outcome payloads, the worker sends phase/log/agent lifecycle protocol messages, the host forwards them through a `liveAgents` pairing ledger, and the engine maintains run ids solely to correlate those notifications.
-
-The progress vocabulary is not merely unused; it cannot serve its only named future owner without redesign. `WorkflowRunInfo` contains `{id, meta}` but no parent agent, session, or tool-call identity, while the model-facing tool never exposes the run id. A global ACP listener could not route an event to the correct client session. `meta.phases` is never consulted, `phase(title)` does not validate against it, phase `detail`/`model` and agent `label`/`phase` feed only events, and `whenToUse` is validated and copied but never rendered or selected. `phase()` and `log()` still cross the worker boundary despite having no receiver.
-
-The live handle repeats event-era data after those observers disappear. `WorkflowRun.id` has no non-event consumer, while the tool reads `run.meta.name` only to render a value it already owns as `args.meta.name`; neither belongs on the execution/cancellation handle.
-
-Cancellation also has two public channels for one synchronous start. `WorkflowStartRequest.signal` is passed to the worker host, while the sole production caller separately bridges the same signal to `WorkflowRun.cancel()`. Because `start()` returns the run before control can yield, there is no readiness window that requires request-time cancellation; the duplicate signal adds host listener/disarm state without closing a race.
-
-`WorkflowError.fatal` is the same speculative branch in miniature: every production construction is fatal, `fatal: false` exists only in tests, and combinators already distinguish workflow failures with `instanceof`.
-
-## Proposal
-
-Keep the exercised core: `agent(prompt, { schema, model })`, `parallel`, `pipeline`, `args`, concurrency/agent caps, cancellation, bounded disposal, structured results, worker isolation, and foreground tool collection. Remove all `workflow/*` events and their event-only info/outcome types; remove `phase()`, `log()`, agent `label`/`phase`, phase declarations, `whenToUse`, and their worker messages/host observers; collapse workflow metadata to the name the tool actually uses; remove event-only run ids/meta snapshots and the synthesized agent-end ledger. Shrink `WorkflowRun` to `result`, `cancel()`, and `dispose()`; the tool renders the request-owned name. Remove `WorkflowStartRequest.signal` and the worker host's input-signal listener/disarm state, retaining the caller-owned bridge from its abort signal to `run.cancel()`. Make `WorkflowError` one fatal error class without a boolean mode or `isFatalWorkflowError()` helper.
-
-Amend the implemented dynamic-workflow Agent Note and update the seam/tool/worker READMEs, tool schema, generated catalogs and package graph, worker type-equivalence records, unit tests, and workflow snapshot/header fixtures. Progress UI work, if commissioned, starts from a correlation contract that names the parent agent/session/tool call instead of reviving this protocol unchanged.
-
-## Alternatives considered
-
-**Keep the prebuilt observation vocabulary for a future UI.** The current shape resembles Claude Code dynamic-workflow metadata, and the host deliberately pairs each forwarded agent start with either the worker's end or a synthesized terminal end. Removing it gives up compatibility-by-shape and makes progress UI a new design task, but the existing payloads still lack routable ownership, so balanced lifecycles alone cannot make the named ACP owner viable without redesign.
-
-## Acceptance criteria
-
-- The workflow public contract contains only execution, cancellation, result, and disposal contracts with a production consumer.
-- No workflow event, phase/log protocol message, run-id generator, progress-only metadata, host pairing ledger, or fatal-mode branch remains.
-- The run handle has no id/meta echoes, and cancellation has one holder-owned channel after synchronous `start()` returns.
-- Parallel/pipeline behavior, caps, cancellation quiescence, worker containment, structured output, and the model-facing workflow scenarios retain coverage.
-- Typecheck, coverage, snapshots, doc-sync, module-graph verification, build, and hygiene pass.
-
-## Risks
-
-This is a compile-visible contraction of the workflow DSL, event taxonomy, handle, and start request. Existing workflow calls that supply descriptive metadata, and scripts that use `phase`, `log`, or labels, must shrink; programmatic callers bridge their own abort source to the returned handle; and a future observer must add a better-correlated event contract. The execution semantics that make workflows useful do not change.

-# Agent Note: 将工作流收缩至已使用的前台核心
-
-Status: rejected — 工作流进度是有意设计的观测接口；应通过消费方使其发挥作用，而非删除它。
-
-[English](2026-07-12-collapse-workflow-to-foreground-core.md) | 中文
-
-## 问题
-
-工作流能力在前台执行用于编排 subagent 的 JavaScript，但它同时携带了一套无人消费的进度观测系统。没有任何生产环境的监听器订阅六个 `workflow/*` 事件中的任何一个；监听器仅存在于工作流测试中。尽管如此，seam 定义了 run/phase/agent（智能体）outcome 载荷，worker 发送 phase/log/agent 生命周期协议消息，host 通过一个 `liveAgents` 配对账本转发它们，引擎维护 run id 仅仅是为了关联这些通知。
-
-这套进度词汇不仅仅是未被使用；它在不经重新设计的情况下也无法服务于其唯一已命名的未来消费方。`WorkflowRunInfo` 包含 `{id, meta}` 但没有父 agent、会话或工具调用标识，而面向模型的工具也从不暴露 run id。一个全局 ACP（Agent Client Protocol）监听器无法将事件路由到正确的客户端会话。`meta.phases` 从未被查询，`phase(title)` 不对其做校验，phase 的 `detail`/`model` 和 agent 的 `label`/`phase` 仅供事件消费，`whenToUse` 被校验和复制但从未被渲染或用于选择。`phase()` 和 `log()` 仍然跨越 worker 边界，尽管没有接收方。
-
-这些观测者移除后，live handle 仍重复携带事件机制所需的数据。`WorkflowRun.id` 没有非事件消费方，而工具读取 `run.meta.name` 只是为了渲染一个它已经以 `args.meta.name` 形式持有的值；两者都不属于执行/取消 handle。
-
-取消机制也为一个同步启动提供了两条公开通道。`WorkflowStartRequest.signal` 被传递给 worker host，而唯一的生产调用方另外将同一个 signal 桥接到 `WorkflowRun.cancel()`。因为 `start()` 在控制权让出之前就返回了 run，不存在需要请求时取消的就绪窗口；重复的 signal 增加了 host 的 listener/disarm 状态却没有封堵任何竞态。
-
-`WorkflowError.fatal` 是同一种推测性分支的微缩版：生产代码中的构造全都采用 fatal 模式，`fatal: false` 仅存在于测试中，组合子已经通过 `instanceof` 区分工作流失败。
-
-## 提案
-
-保留已使用的核心：`agent(prompt, { schema, model })`、`parallel`、`pipeline`、`args`、并发/agent 上限、取消、有界 dispose（资源释放）、结构化结果、worker 隔离与前台工具收集。移除所有 `workflow/*` 事件及其仅供事件使用的 info/outcome 类型；移除 `phase()`、`log()`、agent 的 `label`/`phase`、phase 声明、`whenToUse` 及其 worker 消息/host 观测者；将工作流元数据收缩为工具实际使用的 name；移除仅供事件使用的 run id/meta 快照与合成的 agent-end 账本。将 `WorkflowRun` 收缩为 `result`、`cancel()` 和 `dispose()`；工具渲染请求中已有的 name。移除 `WorkflowStartRequest.signal` 及 worker host 的 input-signal listener/disarm 状态，保留调用方从其 abort signal 到 `run.cancel()` 的桥接。将 `WorkflowError` 变为单一的 fatal 错误类，不再有布尔模式或 `isFatalWorkflowError()` 辅助函数。
-
-修订已实施的动态工作流 Agent Note，并更新 seam/工具/worker README、工具 schema、生成的 catalog 与包依赖图、worker type-equiv 记录、单元测试以及工作流快照/header fixture（测试前置数据）。如果进度 UI 工作被立项，应从一份命名了父 agent/会话/工具调用的关联约定出发，而非原样复活这套协议。
-
-## 曾考虑的替代方案
-
-**为未来 UI 保留预建的观测词汇。** 当前形态类似 Claude Code 的动态工作流元数据，host 有意地将每个转发的 agent start 与 worker 的 end 或一个合成的终止 end 配对。移除它意味着放弃形态兼容性，使进度 UI 成为一项全新的设计任务；但现有载荷仍缺少可路由的归属信息，因此仅靠成对完整的生命周期也无法在不重新设计的情况下让已命名的 ACP 消费方可行。
-
-## 验收标准
-
-- 工作流公开约定仅包含有生产消费方的执行、取消、结果与 dispose 约定。
-- 不再保留任何工作流事件、phase/log 协议消息、run-id 生成器、仅供进度使用的元数据、host 配对账本或 fatal 模式分支。
-- run handle 不再有 id/meta 回显，取消在同步 `start()` 返回后只有一条持有者拥有的通道。
-- parallel/pipeline 行为、上限、取消后的完全停稳、worker 隔离、结构化输出与面向模型的工作流场景保持测试覆盖。
-- 类型检查、覆盖率、快照、doc-sync（文档同步门禁）、module-graph 校验、构建与 hygiene 全部通过。
-
-## 风险
-
-这是对工作流 DSL、事件分类体系、handle 与 start request 的编译可见收缩。现有提供描述性元数据的工作流调用，以及使用 `phase`、`log` 或 label 的脚本，都必须相应精简；程序化调用方需自行将 abort source 桥接到返回的 handle；未来的观测者必须添加一个关联性更好的事件约定。使工作流有用的执行语义不变。

 - Treat dual LLM adapters as intentional by default. Session persistence is different: JSONL is the sole first-party provider, while the backend-neutral service remains available to out-of-tree providers. Do not propose deleting an LLM twin or the persistence seam as "low effort" unless the user explicitly overrides that constraint. Removing an unused method or hook inside a protected seam can still be valid if it does not collapse the protected design.

+The briefing-driven path matches guidance-corpus quality at a fraction of the cost; the archived [briefed-updates Agent Note](../../notes/archived/process/2026-07-26-briefed-minimal-translation-updates.md) records the benchmark evidence.
 
 1. **Generate the briefing**: `pnpm run gen-translation-brief <any file of the pair>` (no arguments briefs every out-of-sync pair). The briefing maps the change at the narrowest safely aligned granularity — changed Markdown units (paragraph, table row, list item, heading), then whole heading sections, then whole document — and contains the authored side's diff since the last confirmed-consistent state, each changed unit's last-confirmed source, current source, and current counterpart text (with line numbers), the terminology rows the change touches, first-occurrence movement notes, and a digest of the binding update rules.
 2. **Mechanical-only diff? `--apply` it.** When every change lies inside code fences that the pair shares byte-identically, the briefing says so; `pnpm run gen-translation-brief --apply <pair>` splices the edited fences into the counterpart and structure-validates the result before writing — no subagent, no hand-editing.

Explicit object nodes declare `additionalProperties: true | false`; the implicit parameter root stays open. You still hand-check constraints the DSL does not express, such as non-empty strings, positive numbers, or cross-field rules. Raw JSON-Schema tools registered directly own their input validation.
+- **Args are validated for you.** `defineTool` validates model-generated `arguments` against the unified `ParameterSchemaSpec` before `execute` runs (types, required keys, literal constraints, exact-one unions, and nested values), so inside `execute` the args match `InferArgs`.

You still hand-check constraints the DSL does not express, such as non-empty strings, positive numbers, or cross-field rules. Raw JSON-Schema tools registered directly own their input validation.
 - **Registration borrows your readonly definition.** A typed same-process contribution is not a serialization boundary; do not mutate its schema or replace callbacks after registration. `schemas()` materializes only the explicit model-facing projection. To hot-swap a tool, dispose its owning effect and register the replacement; mutable state inside the callback's closure remains ordinary plugin state.
 - **Execution identity is protected.** The registry materializes `arguments` as detached lossless JSON in one recursive pass, freezes that value before policy starts, and assigns an opaque `exec.token`; `callId`, `name`, `arguments`, `agent`, `token`, the required caller-owned `signal`, and an optional enclosing-transport `parent` token stay immutable through dispatch. `parent` is identity-only and exposes no live outer execution. Treat `args` as readonly input. Only an around-dispatch wrapper receives a mutable view, and it may replace and restore the required `exec.signal` to impose a deadline but cannot remove it.
 - **Declare and return one canonical JSON value.** `output.schema` uses `ValueSchemaSpec` and may have an object, array, scalar, or null root. `execute` returns only the inferred value; the registry snapshots it as lossless JSON, validates it, freezes it, and passes it to `output.render(args, value)`. Do not return content blocks from the body or make callers parse prose for ids and fields.

 - **执行身份受保护。** 注册表在一次递归遍历中将 `arguments` 物化为分离的无损 JSON，在策略开始前冻结该值，并分配一个不透明的 `exec.token`；`callId`、`name`、`arguments`、`agent`、`token`、必填且由调用方持有的 `signal`，以及可选的外层传输 `parent` token 在整个分发过程中保持不可变。`parent` 仅用于身份标识，不暴露活跃的外层执行。请将 `args` 视为只读输入。只有 around-dispatch 包装器会收到可变视图；它可以替换并恢复必填的 `exec.signal` 以施加截止时间，但不能移除该信号。
 - **声明并返回一个规范 JSON 值。** `output.schema` 使用 `ValueSchemaSpec`，根可以是对象、数组、标量或 null。`execute` 只返回推导出的值；注册表将其快照为无损 JSON，完成校验和冻结后，再传给 `output.render(args, value)`。工具主体不要返回内容块，也不要迫使调用方从自然语言中解析 id 和字段。

 Both tsdown passes use the same complete workspace match. They neither scan build artifacts to discover Client packages nor maintain a Host/Client package filter list. Package-local tsdown configs select entries for the current phase through `DSH_BUILD_FACE`: an ordinary Client plugin produces both its Node loader and browser bundle during the Client phase; `api-remotes` uses `hostPhase: true` to produce its Host entry early and only its browser bundle during the Client phase. Tsdown consumes only the JavaScript emitted to `lib/types` by the preceding tsc phase.
 
-Typert runs only during Host tsdown, seeded by `tsconfig.host.json`. It analyzes Host types and generates both Host reflection artifacts and the Host-for-Client Remote projection; Client tsdown does not start Typert. Consequently, `pnpm run typecheck` runs the complete Host lib phase before Client tsc, while `pnpm run build` continues through Client tsdown and the Web build. The [API Remotes generated-contract build note](../.agents/notes/implemented/process/2026-08-08-api-remotes-generated-contract-build.md) records this ordering decision.
+Typert runs only during Host tsdown, seeded by `tsconfig.host.json`.

Consequently, `pnpm run typecheck` runs the complete Host lib phase before Client tsc, while `pnpm run build` continues through Client tsdown and the Web build.
 
 `pnpm run build` embeds the root package version, the seven-character source commit, and a dirty marker when Git reports local changes; it also inherits other caller-supplied `DSH_CLIENT_*` values. `pnpm run build:official` is the cross-platform local equivalent of the CI and release artifact build and omits the local dirty marker. Each successful complete build writes a gitignored record that binds the exact public values to the Vite output and dynamic client bundles; release packing and built Web tests reject a missing record or artifacts changed by a later partial build. `pnpm run dev:web` still requires the artifact tree from a prior complete build, but it samples the current version and Git state once at startup and shares that environment across every watcher stage for the session; it does not validate the complete-build record because the watcher stages rewrite its recorded artifacts.
 
-Static analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly. Generated Host-for-Client Remote declarations are the deliberate exception: the public `typecheck`, `lint`, and `doc-typecheck` commands generate them first, while internal `*:contracts-ready` scripts assume that an invoking public command or scheduler gate already depends on the Typert contract-generation pass or the complete build. See the [solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md) for the two-aggregate setup, the [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md) for tsc-first emit ownership, and the [Typert Remote note](../.agents/notes/implemented/architecture/2026-08-02-typert-remote-method-calls.md) for the gate-preparation contract.

 Business services declare callable methods on the Host with `@Remote` or `@RemoteScope`; the Host build generates Host-for-Client types and runtime contributions, and the Client's `api-remotes` composition loads those contributions under `ctx.remote` and scoped `agentCtx.remote` namespaces. See [API Gateway](api-gateway.md) for the generated artifacts on both sides, their assembly relationships, the SRC development fallback, and the Web build order.

   When two branches contain valid confirmations of the same pair, the installed `dsh-translation-pairing` Git merge driver composes a new record only if Git's default text merge succeeds for both recorded owner-blob triplets and the merged pair retains its required switchers and structural signature. The Chinese file must retain its English backlink; an authored English source must retain its Chinese link, while a listed generated English source is exempt. Any structure the driver cannot verify remains an ordinary conflict; `pnpm run resolve-translation-pairing-conflicts` applies the same fail-closed operation to a merge that has already stopped, stages every safe pairing record, and exits unsuccessfully when other pairing conflicts remain. The [automatic pairing merges Agent Note](../../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md) owns the mechanism and alternatives.
 - **Language switcher.** The Chinese file always links back immediately after its H1 heading with `[English](foo.md) | 中文`. An authored English file reciprocates there with `English | [中文](foo.zh.md)`; a listed generated English source omits that line so it remains byte-identical to generator output. A README published outside GitHub, such as PyPI project metadata, may use the canonical `https://github.com/deepseek-ai/deepseek-harness/blob/master/<repository-path>` URL to the same counterpart so the switcher still resolves there.

 Every event type that can appear in a session's durable event log: the complete persisted `SessionEvent` envelope and each member of the merge-extensible `SessionEventMap` — the owning vocabulary in `@deepseek-ai/dsh-session` plus every plugin declaration merge into `@deepseek-ai/dsh-session/types` in this repo — with source JSDoc, full payload declaration, surface badge, and declaration site. It complements [session.md](subsystems/session.md) (surface ordering and the `deriveMessages()` projection), [persistence.md](subsystems/persistence.md) (how the log is made durable), and the generated region of [session.md](subsystems/session.md#cordis-surface) (the live bus wiring — a log event is NOT a cordis event; it reaches listeners via the single `session/event` emit).

 The envelope declarations below compose each event's `type`, monotonic `seq`, epoch-ms `time`, `data`, the optional `ignorable` unknown-type skip marker, and the conditional `surfaceOp`/`sourceEventSeqs` fields. **surface** marks a `SurfaceEventType` member: it produces an LLM message and declares how it joins the surface list. **log-only** marks everything else: a durable, replayable record with no derived-history contribution. Every payload is JSON-serializable (enforced at `Session.append`). Current writers stamp `SESSION_FORMAT_VERSION`; supported historical artifacts reach this current vocabulary through the build-static adjacent migration catalog ([the version lifecycle](subsystems/persistence.md)). Scope: the packages in this repo; a downstream plugin can merge further current-version event types, which are outside this catalog by construction and require an explicit disposition at a later format edge.

 - **Provider stalls are bounded at the transport.** Both shipping remote adapters expose positive finite `streamIdleTimeoutMs` with a five-minute default. The watchdog arms only while iterator `next()` is outstanding, uses one stable signal for the whole request, maps its own expiry to `TIMEOUT`, and keeps an earlier caller abort as `ABORTED`.
 - **Context overflow has one canonical code.** Both DeepSeek adapters classify explicit provider detail through `isContextWindowExceededError()` and surface `CONTEXT_WINDOW_EXCEEDED`, whether the failure arrives as a thrown HTTP `LlmError` or an in-band finish error. Consumers route on the code, never provider text.

 - **Every provider HTTP request carries the app-attribution header.** Adapters send `attributionHeaders()` (below) - the `User-Agent` baseline - and prove it with a wire-level test.
 - **Replay state is adapter-owned; its split is shared.** A successful `finish` may carry a `ReplayEnvelope`: opaque response-level metadata plus optional per-block entries aligned with the emitted block sequence. The alignment is the harness's vocabulary — when assembly drops a block it drops the entry at the same position, so stored metadata always describes stored content. The loop stores the pruned envelope with the assembled assistant message. On a later request, `LlmRuntime` passes the state only when the historical provider and target provider are currently registered to the exact same adapter instance. That adapter validates the state and owns any cross-model or cross-provider conversion; other adapters receive the provider-neutral content plus provider/model fields without the private state. Durable content stays authoritative: a stored state the reading adapter cannot use degrades that one message to provider-neutral conversion with a diagnostic instead of failing the request.

 - **回放状态归适配器所有；其切分是共享词汇。** 成功的 `finish` 可以携带一个 `ReplayEnvelope`：不透明的响应级元数据，加上与发射块序列对齐的可选逐块条目。对齐关系是 harness 的词汇——组装丢弃某个块时，同一位置的条目一并丢弃，因此存储的元数据始终描述存储的内容。循环把裁剪后的数据与组装后的 assistant 消息一起存储。后续请求中，仅当历史提供方与目标提供方当前注册到完全相同的适配器实例时，`LlmRuntime` 才会传递该状态。该适配器负责校验状态并拥有所有跨模型或跨提供方转换；其他适配器只会收到提供方无关的内容以及提供方／模型字段，不会收到私有状态。持久化内容保持权威：读取适配器无法使用的已存状态只会把这一条消息降级为提供方无关转换并带出诊断，而不是让请求失败。

 The subagent seam lets an agent delegate work to a child agent. Like [bash](shell.md), it is **one optional capability**, not part of the agent loop, so its types live here rather than in [core.md](core.md). It differs from the other capability seams because **multiple provider implementations coexist** in one context, registered by name (`ctx.subagents`), while bash allows only one executor. Its registry follows the [LLM adapter registry](llm-streaming.md), not the single-service bash executor.

-`SubagentRuntime.listChildren(parentSessionId)` enumerates the parent's direct session-backed subagents from the live-preferred merge of `ctx.sessions` and the session-query engine's `listSessions()` — no Agent is loaded or resumed. Candidates are the direct children whose durable header carries `origin: 'subagent'`; the marker classifies enumeration and coarse generic-route denial but cannot establish a valid descriptor, resumability, or authorization — the projection fold owns identity, and the Activation contract owns resume. Each row's `mode`/`label` is the registered `subagent` projection unit's value, served through a three-rung ladder: the registry's watermark cache for a live child (zero log reads); the optional projection checkpoint cache for a cold one (`cachedSnapshot` — an identity passing the own-suffix seq gate is final, because an own descriptor is immutable once appended); otherwise one `query.observeSession()` cold observation folded through the registry (bounded concurrency, recomputed per listing). The cache is a pure optional accelerator: absent, serving the `null` sentinel or missing the key, failing the seq gate, or faulting, it falls silently through to the authoritative refold. The fold is `subagent/descriptor` last-wins with no failure channel: the child's own descriptor overrides a fork-seeded ancestor's, and a malformed or unknown-version payload folds to a serializable `null` sentinel, treated as no value. The result is one `SubagentListEntry[]` in `createdAt`-then-id order: a served identity yields a `child` entry with `mode: 'one-shot' | 'continuable'` and `activity: 'running' | 'inactive'`; continuable entries always carry `label`, while one-shot entries carry it only when the start caller supplied presentation metadata. A settled candidate whose fold served no identity yields a `corrupt` diagnostic — missing, malformed, and unknown-version descriptors deliberately undistinguished (`unsupported` remains in the type but is never produced); a running candidate without an identity is omitted (the creation window before its descriptor lands); a failed cold inspection yields one `unavailable` diagnostic retried on the next listing, so one damaged sibling cannot hide healthy children. `hasChildren` marks a direct descendant with durable subagent origin, read from the same merged material. Activity snapshots only whether the logical record is live in `ctx.sessions`, not outcome or resumability. Absent persistence, enumeration is live-only rather than an error — a cold child cannot be resumed then either. `listChildren()` throws `SubagentError` with code `SUBAGENT_CONTROL_PROJECTIONS_UNAVAILABLE` when the `ctx.sessionProjections` registry is absent and `SUBAGENT_CONTROL_SESSION_STORE_UNAVAILABLE` when the session store is, both checked before any read so a deployment with zero children still fails deterministically; the list tool requires `ctx.subagents` and `ctx.agents` at plugin load. A service consumer such as a UI can display both modes and choose an unlabeled one-shot fallback, while the model-facing `list_agents` adapter (the separately loadable `/list-agents` plugin of [dsh-tool-subagent-control](../../packages/subagent/tool-subagent-control)) keeps only continuable entries and refines status through the live Agent registry into its own `running`/`idle`/`ready` vocabulary, whose `ready` names a storage-only child as resumable rather than terminal. Listing does not consult the continuation manager's Activation map, Agent registry, or provider availability; `send_message` remains the authoritative delivery-time operation, and a listed running continuable child may still reject delivery as an ownership conflict.

 `SubagentRuntime.listDescendants(rootSessionId)` 将同一份实时优先语料与基于投影的解释应用到根的完整后代树，并按稳定 pre-order 输出。普通会话和一次性 child 仍作为遍历节点，因此其下的可继续后代仍可发现；只有 `origin: 'subagent'` 的候选会生成条目。每个返回的 child 或 diagnostic 都从枚举所得的持久 header 附加树位置；冷检查在提供身份前还会重新校验完整生命周期：

 - **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
 - **Owner-local expected output** (`pnpm run test:expected`): keyless assembled CLI/process expectations without a recorded-session round trip. Drivers use `*.expected.e2e.ts` beside `tests/expected/`; CI runs built exports. Package/script expectations use `test`, while browser expectations use `test:web`.
 - **Snapshot** (`pnpm run test:snapshot`): a top-level scenario's highest recorded parent generation supplies user input and model replay, then serves as the expected persisted result. Parent filenames are `session[.vN].jsonl`; child roles are `session.<ordinal>[.vN].jsonl`; v0 omits `.v0`, positive versions require lowercase `.vN`, and each filename must agree with its header. Process scenarios start through `dsh`: headless owns one-shot behavior, the SDK owns persistent control, ACP owns automation-protocol behavior, and Web retains browser/ARIA evidence beside the same Session. `snapshot.yml` declares the profile, composition/header class, recording policy, exceptional replay or input metadata, and workspace facts. Typed tokens preserve parent/child identity relationships; only header pins own prompt/schema sidecars. A mutating scenario independently compares the complete `workspace.expected/` tree, which record and refresh never rewrite. Use `test:snapshot:record` when a model transcript changes and `test:snapshot:refresh` when replay input remains valid; review every resulting diff.
-- **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares session-driven output under `snapshots/web/` and UI-only output under `apps/web/tests/expected/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` [builds first](../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md) for plugin CSS.

 Session fixtures retain headers and payloads but omit body sequence/time envelopes; replay synthesizes them. Replay, record, and refresh select each parent/child role's highest generation. Current v2 uses `.v2`, one row per event, and embedded compact Assistant streams; retained v0 (suffixless) and v1 (`.v1`) may keep canonical packed rows for migration coverage. [The migrator](../scripts/migrate-packed-session-fixtures.ts) rewrites older historical layouts.

 Every model-facing tool a shipped plugin contributes to `ctx.tools`: the `name`, `description`, and JSON-Schema `parameters` the model receives via the system-prompt assembly. It complements the [subsystem pages](subsystems/core.md) (the types plus each page's generated Cordis API region) — this page is the *tools* the agent is offered.
 
-This file is GENERATED and verified fresh by `pnpm run verify-tool-catalog` (part of `doc-sync`) — do not edit it by hand. Unlike the cordis catalog (a pure source-AST pass), this generator BOOTS each tool plugin on a real context and reads `ctx.tools.schemas()`, because a tool schema is not statically knowable (runtime-spread enums, concatenated descriptions, config-driven names, raw-JSON-Schema MCP tools). A completeness guard globs `packages/*/tool-*` and fails if any package is missing from the generator's boot manifest, so a new tool cannot be silently undocumented.

 Scope: shipped product tools under `packages/*/tool-*`, each booted with its DEFAULT config, except where a Config field is REQUIRED with no default — there the generator must choose, and the per-package note records which branch this page shows. The registered tool NAME can be a load-time config (e.g. `tool-subagent`'s `toolName`), so a deployment may expose a package under a different or additional name — a per-package note records those shipped aliases where they exist. The `examples/` demo tools (e.g. `echo`) are excluded, matching the cordis catalog's packages-only scope.

Its legal keys are exactly the Host assembly's forwarding selection, and the listener type is the owning package's own Cordis `Events` declaration, so no second signature can drift from it.

The Client Remote service registers the `$events` pump as a Connection generation source when it activates, whether any `$on` listener exists. Browsers use Remote mux, while in-process compositions use `connection.rpc.open`; the opening `ready` item establishes a Connection generation and supplies its Host facts. Carrier failure, Remote stream failure, unexpected normal completion, a non-ready opening item, or a malformed event item ends that generation and lets Connection reopen it under continuous, capped jittered exponential backoff. Ordinary notifications run in registration order and isolate listener failures. Agent-scoped waterfalls let a listener return a result, call `next()`, or reject; Gateway returns that outcome through the existing HTTP unary carrier.

 ## Turn Process Folding
 
-Settings → General exposes a persisted `Normal` / `Compact` conversation-display preference in the `ui-chat` namespace; `Compact` is the default. Normal leaves process rows visible and renders no Turn-process control. In Compact mode, the System prompt remains independently visible before the opening User throughout the Turn. Context injection, reasoning, Assistant material, Tool rows, and Retry rows remain expanded while a Turn is open. At `turn/end`, its latest Step becomes the final-answer boundary only when it contains non-blank text, an image, or an unknown visible block—and no Tool-call block; preceding Context injection, reasoning, earlier Assistant material, Tool rows, and Retry rows then collapse by default. The control reports Turn-wide durable counts for non-subagent Tool calls, reply-bearing Assistant messages before the final answer, and subagent delegation calls; zero-valued segments are omitted, the Tool and subagent figures are mutually exclusive, and neither System prompt nor Context injection contributes a count. When all three counts are zero, the process still folds and the control reads `Thought for a while`. A full-width divider below the summary separates it from the answer or expanded process rows. User and steering messages, System prompt, error, max-token, and turn-tail rows stay outside, and a closed Turn with no final answer keeps all process evidence visible. A newly available process control is inserted without changing the relative order of existing rows: opening human input precedes the control and process rows from their first projection, while System prompt remains above that input. While older history remains available through Load earlier, process controls stay absent and no members are hidden; once history is complete, every eligible closed Turn uses the collapsed default immediately. Stable Chat Node Seats keep every renderer mounted, hidden members add no flow spacing, and a closed control sits 8px above its answer only when no independent input intervenes. Completion collapse does not depend on tail-follow position, so a reader above the tail may see the transcript reflow. An automatic collapse that would hide keyboard focus keeps the group open and leaves focus in place; a manual close focuses the process control before hiding its members. The session-scoped store records only manually expanded Turn-and-answer-Step generations; a different answer generation starts collapsed ([folding decision](../../../.agents/notes/implemented/feature/2026-08-14-web-turn-process-folding.md), [ordering decision](../../../.agents/notes/implemented/bug-fix/2026-08-26-stable-turn-process-order.md)).

-Chat restores semantic anchors across history prepend and renderer remounts. While the reader is pinned to the floor, `ResizeObserver` follows the new floor and selects the latest loaded Turn without reading row geometry. Once the reader moves away, flow-height changes preserve the top position and the reading-line geometry selects the active Turn. Turn-rail previews paint above sticky Markdown code-block banners, while the rail frame remains inside the transcript band above the composer ([loaded-Turn navigation](../../../.agents/notes/implemented/feature/2026-08-25-loaded-turn-chat-navigation.md)).

The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `LinkIcon` draws the leading category glyph for clickable artifact links — globe, folder, code, image, document, or plain paper, all riding `currentColor` — and `classifyLinkPath` derives a file path's category from its extension. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Every state reserves the widest supplied label and uses fixed icon and text columns, so copy changes do not move or resize the control. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `useAnchoredPosition` and `useAnchoredMaxHeight` keep floating panels and bottom-anchored overlays clamped to the viewport and following their anchor. `HoverCard` keeps its portaled preview reachable across the anchor gap and can expose a copy button through the `copyText` prop. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order ([ranking decision](../../../.agents/notes/implemented/feature/2026-08-04-web-slash-command-fuzzy-discovery.md)).

 ### Rendering agent output
 
-`MarkdownText` renders untrusted GFM and TeX math, blocks unsafe links and images, and can turn resolved file mentions into explicit controls. While a reply streams, it freezes completed blocks, advances a top-level open fence by completed lines, and highlights that fence from saved Shiki grammar state. Completed token lines enter fixed-size React groups, so later chunks reconcile only the growing group; an unchanged fence retains that DOM when the final full parse resolves cross-document syntax ([incremental renderer](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.md), [streaming fence highlighting](../../../.agents/notes/implemented/feature/2026-08-20-web-streaming-fence-highlight.md)). `TerminalBlock`, `ReadBlock`, `DiffBlock`, `SearchBlock`, and `WebBlock` render the matching tool-result intent with copy controls, overflow handling, and ANSI processing where applicable. `JsonTree` and `JsonBlock` inspect JSON values read-only, while `projectUserText` projects sent user text into inline plain runs and reference chips for the message bubble and queue rows.

 ### Streaming markdown
 
-While a reply streams, `MarkdownText` parses incrementally: all but the trailing two blocks freeze as cached React elements and only the source tail re-parses per chunk, so per-chunk work tracks the tail instead of the whole reply. A final unclosed top-level fence keeps its parsed code node and sends only the last completed line plus the current partial line through the same GFM grammar; a closing fence or ambiguous parse returns to the ordinary tail path. Highlighting likewise resumes from saved Shiki grammar state and publishes only newly completed lines plus the mutable tail. `CodeBlock` seals completed lines into fixed-size React groups, reuses earlier groups, and retains the whole highlighted tree across settlement when code and language are unchanged. The settled full parse still resolves references that crossed the freeze boundary ([incremental renderer](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.md), [streaming fence highlighting](../../../.agents/notes/implemented/feature/2026-08-20-web-streaming-fence-highlight.md)).

 ### What the source offers
 
-Ordinary-session candidates come from the `skills/list` Remote; the host serves every user-invocable skill, and a `modelInvocable: false` entry (a `disable-model-invocation` skill, whose only entry point is this path) wears the user-only marker as a description prefix in the active language. Results rank through the `/` menu's shared name ranker, `rankByName` from ui-primitives: the query matches a case-insensitive ordered subsequence of the skill name, prefix hits rank first, and ties keep the host order ([ranking decision](../../../.agents/notes/implemented/feature/2026-08-04-web-slash-command-fuzzy-discovery.md)). A failed `skills/list` call is logged and folded into a silent menu-group drop — the menu shows only pending/ready states.

 - **`SESSION_FORMAT_VERSION` names only the current logical representation** — historical headers and events remain in adjacent format packages, while persistence publishes a complete supported chain before constructing `Session`; equal-version unknown events still require the envelope's explicit `ignorable` marker ([mechanism](../../../.agents/notes/implemented/architecture/2026-08-31-released-session-format-migrations.md)).
 - **`TurnEndReasonMap` omits the ACP-named `refusal` / `max_turn_requests` variants** — producer-gated: they land when an adapter or the loop first emits them.
 - **No session tree beyond fork** — a pi-style entry tree over branched sessions is deferred unless a consumer needs more than boundary-based forking.

 Three artifacts from one tsdown pipeline:
 
 - **`lib/index.js` (assembly library)** — `createWorkerHost`/`startWorkerHost` mount the base image and any ordered data overlays (`storage/`), install the module loader (`module-system/`) and the `process` shim, boot the tree through the image's own `dsh-app-boot`, and hand the tunnel its serving seams. Overlays may replace files only under `home/` and `workspace/`; they cannot replace the base manifest, configuration, or modules. The image layout contract (`image-layout.ts`: virtual root, config/manifest paths, empty directories, the `lowered` wrapper-contract gate) is shared with the packer. Boot patches force the deployment-shaped rows: frontend serving off, JSONL session logs on the plaintext path, preset roots onto the image's `config/agent-presets`.
-- **`lib/worker.js` (worker bundle)** — the assembly plus this package's Node-compatibility layer as one self-contained ES module. The module proxy table (`module-proxies.ts`) is the only platform fork: `node:*` builtins over VFS/tunnel/browser primitives, structural stubs that fail loud on the console for what a browser cannot do, and native/binary package replacements. `node:module` supplies `createRequire().resolve` and `.resolve.paths()` over the image package root, so unchanged packages can discover manifests without evaluating their modules. The global `process` shim carries Node detection fields including `title`, preventing Worker execution from entering DOM-only branches. The pack-time parser reports statically named module requests, including module-scope direct calls of the form `createRequire(import.meta.url)('pkg')` through a named `node:module` or `module` import, to the packer's reachability walk. Stored, CommonJS-obtained, and rebased `createRequire` calls require image entry seeds. VFS mutations drive `node:fs` callback, polling, and promise watchers; open descriptors retain file identity and access mode across rename, replacement, and unlink; `readable-stream` supplies the stream state machine used by file streams and unchanged image packages such as Chokidar and readdirp. AsyncLocalStorage carries sync-stack causality across `await` through the snapshot/restore faces the pack-time lowering injects. The worker holds no compiler: an image the packer did not lower is refused at mount ([note](../../../.agents/notes/implemented/architecture/2026-08-20-webworker-pack-lowering-and-preview.md)).

 - **`src/shell/` (the worker's own process layer)** — a browser worker cannot fork, so `node:child_process` is not a stub but an implementation: `spawn` starts the command in its own Web Worker — this same bundle, told by its first frame to be a shell process — and reports it through the `ChildProcess` surface the subprocess service consumes. The command runs off the host's thread, `SIGKILL` terminates it whatever it is doing, and it reaches the VFS only by message (the host serves those frames). Worker platform executables preserve native-package protocols such as Landlock without replacing their JavaScript packages or coupling their implementations to `node:child_process`; ordinary commands use the package's evaluator and coreutils command table. The grammar is `@yarnpkg/parsers`' `parseShell`, while `execSync`/`fork` still refuse because they need a real process.
 - **`lib/client.js` (page half)** — startup has two independent stages. `chooseWorkerHostSource({ image?, fixtureManifest? })` optionally owns the boot barrier and fixture manifest: without `preview-fixture` it waits at the source chooser, while a valid query selects directly; either path returns ordered overlays. `connectWorkerHost(worker, { image?, overlays? })` remains the public base-runtime connector; callers that skip the chooser get an empty overlay list. `apps/web` invokes both and supplies its statically bundled Worker. The opening `init` frame carries the base and ordered overlay URLs, the boot payload delivers the structured index-injection table, and `applyIndexInjections` executes it before the shell entry runs. Script preload rows are advisory and skipped because `/plugins` resources resolve only through the tunnel; `loadBundle` fetches each combo on first demand, embeds its tunnel-only source map as a Base64 data URL, and executes the script as a Blob. The tunnel also exposes fetch-shaped transport, the independent file-upload carrier, and the API client. Request frames preserve Blob bodies through structured clone and transfer `ReadableStream<Uint8Array>` ownership. The Host Worker streams both forms into the route, so neither browser thread creates a complete byte array for a generic-file upload.

 一条 tsdown 管线出三个产物：
 
 - **`lib/index.js`（装配库）**——`createWorkerHost`/`startWorkerHost` 挂载基础镜像和按序排列的数据 overlays（`storage/`）、安装模块加载器（`module-system/`）与 `process` shim、经镜像自带的 `dsh-app-boot` 启动插件树，并把服务缝隙交给隧道。Overlay 只能替换 `home/` 与 `workspace/` 下的文件，不能替换基础 manifest、配置或模块。镜像布局契约（`image-layout.ts`：虚拟根、config/manifest 路径、空目录、`lowered` 包装契约门）与 packer 共享。boot patch 强制部署形态行：关前端静态服务、JSONL 会话日志走明文、preset 根指向镜像内 `config/agent-presets`。
-- **`lib/worker.js`（worker 束）**——装配库加本包的 Node 兼容层，合成一个自含 ES module。模块代理表（`module-proxies.ts`）是唯一平台叉口：`node:*` 内建走 VFS、隧道和浏览器原语，浏览器做不到的走结构化 stub（调用即在 console 报错并抛出），native/binary 包则替换执行后端。`node:module` 在镜像 package 根之上提供 `createRequire().resolve` 与 `.resolve.paths()`，使未修改的包无需执行目标模块即可发现 manifest。全局 `process` shim 带有包括 `title` 在内的 Node 环境识别字段，避免 Worker 执行误入仅适用于 DOM 的分支。pack 期解析器会把名称静态可知的模块请求报告给 packer 的可达性遍历，其中包括通过 `node:module` 或 `module` 具名导入在模块作用域直接发起的 `createRequire(import.meta.url)('pkg')` 调用。保存、经 CommonJS 获取或另设基准的 `createRequire` 调用需要镜像入口种子。VFS mutation 驱动 `node:fs` 的 callback、polling 和 promise watcher；打开的 descriptor 在 rename、replacement 和 unlink 后仍保留文件身份与访问模式；`readable-stream` 提供文件流以及 Chokidar、readdirp 等未修改镜像包所用的流状态机。AsyncLocalStorage 经 pack 时降低注入的 snapshot/restore 面在 `await` 间携带同步栈因果。worker 不带编译器：packer 未降低的镜像在挂载时被拒（[note](../../../.agents/notes/implemented/architecture/2026-08-20-webworker-pack-lowering-and-preview.zh.md)）。

 - **`src/shell/`（worker 自己的进程层）**——浏览器 worker 无法 fork，所以 `node:child_process` 不是 stub 而是实现：`spawn` 把命令放进它自己的 Web Worker——就是这同一个束，由首帧告诉它「你是 shell 进程」——并以 subprocess 服务消费的 `ChildProcess` 面报告结果。命令不占宿主线程，`SIGKILL` 不管它在干什么都能终止它，而它只能靠消息触达 VFS（由宿主应答这些帧）。Worker 平台 executable 在不替换 JavaScript 包、也不把具体实现耦合进 `node:child_process` 的情况下保持 Landlock 等 native 包协议；普通命令使用本包的求值器与 coreutils 命令表。语法来自 `@yarnpkg/parsers` 的 `parseShell`，而 `execSync`/`fork` 依然拒绝，因为它们需要真进程。
 - **`lib/client.js`（页面半）**——启动分为相互独立的两段。`chooseWorkerHostSource({ image?, fixtureManifest? })` 可选地拥有 boot barrier 与 fixture manifest：没有 `preview-fixture` 时停在来源选择面板，合法 query 则直接选择；两条路径都返回按序排列的 overlays。`connectWorkerHost(worker, { image?, overlays? })` 仍是公开的基础运行态连接器；调用方跳过选择器时 overlay 列表为空。`apps/web` 调用这两段并提供静态打包的 Worker。开局 `init` 帧携带基础镜像与按序排列的 overlay URL，boot 载荷送达结构化 index 注入表，`applyIndexInjections` 在壳入口运行前逐行执行。脚本 preload 行只是提示，因此会被跳过：`/plugins` 资源只能经 tunnel 解析，`loadBundle` 会在首次需要时获取 combo、把仅 tunnel 可达的 sourcemap 内嵌为 Base64 data URL，再以 Blob 执行脚本。Tunnel 还暴露 fetch 形式的传输、独立文件上传载体和 API 客户端。请求帧通过结构化克隆保留 Blob 请求体，并转移 `ReadableStream<Uint8Array>` 的所有权。Host Worker 将两种请求体都逐块送入路由，因此通用文件上传不会在任何浏览器线程创建完整字节数组。

 - **Thirteen primitives only** — no delete, rename, copy, or watch; `listDir` lists a single level, with recursion, globbing, pagination, and search out of scope ([directory-listing note](../../../.agents/notes/archived/architecture/2026-07-03-filesystem-directory-listing-seam.md)).
 - **No I/O deadline** — the seam arms no timeout; cancellation is a best-effort optional `AbortSignal` per primitive ([fs family stance](../README.md)).
 - **Resolve-then-operate costs a remote backend two round-trips per tool call** — folding or caching resolution is left to such a backend.

 ### Lifecycle and sync
 
-`apply` resolves the reconnect policy, reserves the `serverName` inside the current registration scope, starts the supervisor, and awaits the initial connection plus discovery. Independent Agent scopes may reuse the same namespace because their tools and transports are isolated; a duplicate inside one scope fails at load. The supervisor serializes every sync — initial, notification, and reconnect — through one queue so two syncs can never interleave their dispose-previous/register-next swap. Disposal cancels pending reconnects, closes the live client, waits for the in-flight attempt and queued syncs to quiesce, and unregisters the current generation. The [auto-reconnect Agent Note](../../../.agents/notes/implemented/feature/2026-08-06-mcp-client-auto-reconnect.md) owns the reconnect decision.

Disposal cancels pending reconnects, closes the live client, waits for the in-flight attempt and queued syncs to quiesce, and unregisters the current generation.
 
 The supervisor listens for `notifications/tools/list_changed` and queues a re-sync; a fetch-phase failure keeps the previous generation registered, while a registration conflict rolls back the attempted generation. Each outage shares one attempt budget: after `maxAttempts` consecutive failures the tools are unregistered and reconnection stops, and a connection that stays up past `maxDelayMs` resets the budget.

 - **Prompt-function readiness.** The tool installs its own `prompt` function that prints a BEL-terminated OSC marker plus a printable prompt; the OSC marker carries the last exit code and the printable prompt settles every command, so a model redefinition of `prompt` degrades readiness to the silence tier.
 - **PSReadLine echo stripped by anchoring.** PowerShell renders submitted input back into the stream; the marker-anchored extraction and a wrapper-source strip remove the echo, and a wrapper that wraps across the terminal width may leave a partial echo in partial-output results.
 - **Reset, never repair.** Any uncertain state — an explicit `exit`, a timeout, a send failure, an abort — closes the shell and starts the next call fresh.

-The invariant companion registers on `ctx.invariants`, validates existing and newly announced sessions once, and then advances a committed per-session turn trace for live appends.

The exclusive open refuses to follow a symlink planted at a guessable temp path; the same-directory sibling keeps the rename on one filesystem; and the rename replaces a symlinked target itself instead of writing through to its referent. A Windows retry keeps the same complete sibling and uses bounded exponential backoff, so temporary use of the target by software outside the cooperative writer lock cannot turn a safe replacement into an immediate failure; the archived [retry decision record](../../../.agents/notes/archived/bug-fix/2026-08-29-windows-atomic-replace-retry.md) documents the original rationale and rejected alternatives.
 
 `withFileLock` creates a `<filename>.lock` sibling with `wx`. `EEXIST` identifies contention directly; `EPERM` does so only when a fresh `lstat` confirms the lock path exists, covering Windows exclusive-create behavior without hiding an unrelated permission failure. The lock records its creator's PID and is removed by the holder in a `finally`; contention backs off exponentially and fails when the per-call `waitMs` deadline (default two seconds) passes.

 `withFileLock` 以 `wx` 创建 `<filename>.lock` 同级文件。`EEXIST` 直接表示竞争；只有一次新的 `lstat` 确认锁路径存在时，`EPERM` 才表示竞争，从而兼容 Windows 的独占创建行为，又不掩盖无关的权限故障。锁记录创建者的 PID，由持有者在 `finally` 中移除；竞争按指数退避，在每次调用声明的 `waitMs` 期限（默认两秒）过后失败。

Subject: [PATCH 05/70] docs(notes): address ds-review-bot feedback on the
 archive audit

- Stop treating three archived records as current authority: bounded-llm
  citation now points at the llm-retry README, the semantic-composer
  proposal cites the runtime-owned child guard as history it builds on,
  and the code-runtime comment states the deferred rationale locally.
- Fix the stale "dsh family stays restricted" claims left without their
  rationale citation: the check-workspace-constraints comment, the
  release publish comment, and the kept npm-release-sequences note now
  record that the family published publicly on 2026-08-13 (87f8e6a728).
- The rejected client-settings-locale-theme body keeps its pristine
  proposal prose with only the Status line and the two link paths whose
  targets this PR archived; the link remaps are required for
  verify-md-links and pairing, and every prose byte is untouched.

 The `agent/request-error` waterfall carries the current `LlmFailure`, an immutable list of prior failures that authorized retries in the consecutive recovery sequence, and the serving registration's immutable retry policy. The loop transports but does not interpret that policy, owns the consecutive failure history, and clears it after a successful model request. Normal `dsh-llm-retry` policy counts durable retry records scheduled by the same exact-provider policy, while `dsh-compaction-basic` keeps its own context-overflow budget. Alternating transient and context-overflow failures therefore consume their owning finite budgets independently; the maximum request count is one plus the sum of the loaded finite budgets.

 For an eligible failure with budget remaining, the one-based transient retry count uses bounded exponential backoff. A valid `providerRetryAfterMs` replaces exponential backoff only when it does not exceed `maxDelayMs`; a longer provider delay causes delegation instead of an earlier retry that violates the provider instruction. Local backoff multiplies by an injected random factor in `[1 - jitterRatio, 1 + jitterRatio]` and clamps the final value to `maxDelayMs`; provider delay is not jittered.

Subject: [PATCH 06/70] fix(client): animate the unloading phase dot and
 correct the catalog

`unloading` marks a teardown the Host is running, which an async disposer
can hold for a while, so the inventory's dot animates it like `loading`
instead of showing the static grey `idle` mark that means no activity.

Correct four documentation facts against the shipped code: StateDot's
render JSDoc still promised four states, the catalog claimed four Tooltip
sides where TooltipSide has three, the Agent Note's geometry audit counted
three matching rules where two match, and the migrated-site and shipped-
appearance counts had drifted.

Record two things the first pass left out: TerminalBlock renders its exit
status as a static Pill, which the Tag/Pill catalog entry now accounts for
by size rather than by interactivity alone, and the disabled inventory tag
changed fill token, which joins the visual-change list.

Pin Tag's eight tones with a stylesheet spec, for the same reason StateDot
has one: CSS Modules resolve to class-name maps in component suites, so a
missing or wrong tone rule passes every render assertion.

 - **`ui-schedule`'s status dot** is a static blue dot for the next run that turns amber when overdue. `StateDot` has no static blue — its only blue is `ongoing`, an animated pixel matrix — and one animation per row in a schedule list would misstate the meaning as well as the appearance.
 - **`ui-plan`'s mode chip** and **`ui-conversation`'s `ReferenceChip`** are interactive: the first is a warning-toned button with hover, focus, disabled, and a close affordance; the second is a Lexical atom node with its own truncation. Neither is a read-only badge.
 - **`ui-trajectory`'s cell tag** and **`ui-user-questions`'s recommendation badge** use their own geometry — a 6px radius at table density, and a 6px radius at 600 weight on the sidebar accent. Forcing either into the capsule baseline would change a deliberate design, not an accidental one.
+- **`TerminalBlock`'s exit-status pill** stays a static `Pill`. It sits on a 24px command line at the pill's own geometry, and `Tag`'s 11px capsule would not fit that row. The read-only/selectable split is the usual guide, but size decides this one, and the catalog says so.
 - **`ui-agent-preset`'s broken badge** shares the capsule geometry but carries a solid error fill that no second site uses, and it is the hover anchor for a tooltip element of its own. `Tag` would have to keep a palette override in the feature stylesheet and depend on cross-file CSS ordering to win it.

 `Tag`, `Switch`, and the extended `StateDot` carry component specs in `packages/client/ui-primitives/tests`, inside the per-file 100% coverage gate. `StateDot`'s palette is pinned by reading its stylesheet: CSS Modules resolve to class-name maps in the component suites, so a state whose color rule is missing renders on the inherited color and no render assertion notices.
 
-The four migrated render sites keep their existing package specs unchanged. The web e2e goldens are ARIA snapshots, and the full replayed web suite passes without re-recording, because the migration preserves every role, accessible name, and state — `Switch` keeps `role="switch"` with `aria-checked`, and the inventory's phase dot keeps its `role="img"` name on a wrapper, since `StateDot` is `aria-hidden`.

The plugin inventory's `conditional` tag read `var(--dsw-alias-state-warning-primary, #b45309)`, and no such alias exists — the real token is `--dsw-alias-state-warn-primary` — so both themes had been painting the hardcoded fallback that [docs/web-styling.md](../../../../docs/web-styling.md) forbids.
 - The rule cannot be checked mechanically. A future author can still copy a control, and only review will catch it. That is the accepted cost of not gating: the alternative rejects legitimate work, and the packages that stay local above are proof that legitimate work exists.
 - `ui-primitives` grows two components that one package each consumes today. The switch in particular is a single-consumer primitive, promoted because it is a general control and because the plugin-management work already in flight will adopt it rather than adding two further copies.

-1. **Check the [ui-primitives catalog](ui-primitives/README.md#component-catalog) before writing a control.** A plugin cannot import another plugin's component, so `ui-primitives` is the only place a control can be shared: reuse the primitive that already fits, and lift a deliberate visual difference into a prop rather than starting a second copy. Writing your own component in your own package is fine when the need is genuinely specific — what is not fine is copying a control that already exists. Once a second package needs the same control, promote it.
+1. **Check the [ui-primitives catalog](ui-primitives/README.md#component-catalog) before writing a control.** A plugin cannot import another plugin's component, so `ui-primitives` is the only place a control can be shared; the catalog states when to reuse, when to promote, and when your own package is the right home.
 
 2. Compose through register: add the slot to `SlotMap`, declare it in its parent entry's `children`, and register your component — see the [Slots reference](../../docs/subsystems/slots.md). No other composition route exists.
 3. Type the props as the four shares (`PropsRuntime` & `PropsRenderSlots` & `PropsStore` & inject face) — derive, don't hand-write. Shared/surviving state goes in a `createXXXStore()` factory declared at register; component-private state stays local.

Subject: [PATCH 07/70] docs(client): finish the five-state and Pill/Tag
 corrections

The `idle` addition left two maintainer-facing statements behind: the
README's limitations entry still listed four supported StateDot states,
and TerminalBlock's run-state JSDoc still counted the union as four while
correctly saying three of them are reachable there.

Pill's header comment still sent every capsule without `onClick` to Tag,
which contradicts both the catalog this pull request corrected and
TerminalBlock's own static read-only Pill two files away. Size separates
the two controls as much as interactivity does, and the comment now says
so. The function JSDoc and the static-mode tests stay as they are: they
describe supported behavior.

Subject: [PATCH 08/70] fix(client): keep the Switch track capsule under the
 global corner shape
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The track's radius is half its height, so its corners consume the whole
side and the global `superellipse(1.5)` squares the ends off — beside a
thumb that already opts out at `border-radius: 50%`, leaving a round knob
in a squared-off slot. Pair `corner-shape: round` with the radius, the way
every full-round radius in the repository does.

The corner-shape stylesheet spec recognizes 50%, 100%, and radii at or
above 99px, so a radius that is full-round only relative to its own box
passes it; the comment records that gap at the rule it affects.

+# Agent Note: File URLs for inserted patch plugins
+
+Status: implemented
+
+English | [中文](2026-09-05-patch-plugin-file-urls.zh.md)
+
+## Problem
+
+Node ESM interprets a Windows drive prefix as a URL scheme and treats filename fragments as URL syntax. Passing filesystem paths directly to plugin imports therefore fails for Windows absolute paths and filenames containing `#` or `%`.
+
+## Decision
+
+Patch-file parsing converts native absolute paths and patch-relative `./` or `../` names to file URLs inside `insert` rows and their nested groups. Package specifiers, existing URLs, existing-entry name assertions, and replacement `config` values retain their meaning. Parsing owns this conversion because it knows the originating patch directory before layers are composed.
+
+The optional `HostResolvedRootInclude` import override separately converts absolute paths for callers selecting an installed-host resolver base. Ordinary CLI profiles do not select that override; it cannot substitute for patch-file conversion.
+
+## Alternatives considered
+
+**Convert only the Python fixture with `Path.as_uri()`.** This avoids one failure but leaves user-authored profile and overlay patches exposed.
+
+**Change the shared Loader base.** This loses per-patch provenance and changes bare-package resolution. File URLs preserve the selected local file without changing the resolver base.
+
+## Consequences
+
+Optional and required patch readers share the conversion. Direct Loader imports and children introduced through replacement group configs remain outside its scope; extending those paths requires their own semantics and coverage.
+
+The patch-reader tests verify conversion and real activation. The built SDK acceptance loads an absolute-path overlay plugin with URL-sensitive filename characters and verifies its filesystem marker, initialization, and shutdown.

+# Agent Note: 插入补丁插件的文件 URL
+
+Status: implemented
+
+[English](2026-09-05-patch-plugin-file-urls.md) | 中文
+
+## Problem
+
+Node ESM 会把 Windows 盘符前缀解释为 URL scheme，并把文件名中的片段字符视为 URL 语法。因此，直接将文件系统路径传给插件导入会使 Windows 绝对路径以及包含 `#` 或 `%` 的文件名加载失败。
+
+## Decision
+
+补丁文件解析将 `insert` 条目及其嵌套分组中的本机绝对路径、相对于补丁文件的 `./` 或 `../` 名称转换为文件 URL。包标识符、已有 URL、已有条目的名称断言及替换用的 `config` 值保持原有含义。解析阶段负责转换，因为在合并各层之前它掌握来源补丁的目录。
+
+可选的 `HostResolvedRootInclude` 导入覆写会另外为选择安装宿主解析基址的调用方转换绝对路径。普通 CLI profile 不选择该覆写，因此它不能代替补丁文件转换。
+
+## Alternatives considered
+
+**只在 Python fixture 中使用 `Path.as_uri()`。** 这能避开一次失败，但用户编写的 profile 和 overlay 补丁仍会遇到问题。
+
+**修改共享 Loader 基址。** 这会丢失逐补丁来源信息并改变裸包解析。文件 URL 保留选定的本地文件，无需修改解析基址。
+
+## Consequences
+
+可选与必需补丁读取器共用该转换。直接 Loader 导入及替换分组 config 引入的子条目不在其范围内；扩展这些路径需要各自的语义与覆盖。
+
+补丁读取器测试验证转换与真实激活。构建后 SDK 验收加载文件名含 URL 敏感字符的绝对路径 overlay 插件，并验证其文件系统标记、初始化与关闭。

+# Agent Note: Package manifest declaration ownership
+
+Status: implemented
+
+English | [中文](2026-09-05-package-manifest-types.zh.md)
+
+## Problem
+
+External packages need Harness manifest types without depending on boot or client implementations. Keeping declarations beside individual readers obscures the complete configuration API and lets overlapping fields diverge.
+
+## Decision
+
+[`@deepseek-ai/dsh-package-manifest`](../../../../packages/util/package-manifest/README.md) owns `DshManifest` and its member declarations in one type-only file. The package belongs to the existing utility group and exports no runtime values. Author declarations and launcher-generated module fallback metadata are explicitly distinguished.
+
+Readers import the shared declarations directly. Boot retains profile loading, raw JSON checks, defaults, and resolved runtime data. Client modules retain their normalized boot graph. The image packer resolves declared paths into directories. The Session catalog generator derives a read-only validated entry with a resolved import path; raw inputs and discovery rules remain local.
+
+App-boot declares a production dependency because its published declarations reference the shared types. Client modules, the private packer, and root scripts use development dependencies because their published APIs do not expose these types. Every package consumer has a TypeScript project reference. External authors import from the utility package; app-boot provides no compatibility re-exports.
+
+## Alternatives considered
+
+**Keep declarations in individual readers.** External authors would depend on runtime implementations, and a partial profile-only definition would omit existing client and build fields.
+
+**Create a separate types group.** The existing utility group accommodates a type-only library without another package category. Runtime service and event declarations stay with their owners.
+
+**Unify the JSON parsers.** Sharing declarations does not require changing validation, errors, defaults, or parsed results; those remain owned by each reader.
+
+## Consequences
+
+Authors gain one public import path at the cost of a published package and explicit dependency edges. Existing app-boot manifest type imports must use the new package. The [profile composition design](2026-08-05-profile-plugin-bundles.md) continues to own runtime semantics; type extraction does not change configuration acceptance or model-visible behavior.
+
+Compiler and packaged NodeNext consumer checks cover public imports. Existing profile, client, image configuration, and Session catalog tests cover reader behavior; documentation checks cover the utility classification and generated package catalogs. Optional declaration fields still require deliberate consumer updates when added.

+# Agent Note: Package manifest 声明归属
+
+Status: implemented
+
+[English](2026-09-05-package-manifest-types.md) | 中文
+
+## 问题
+
+外部包需要 Harness manifest 类型，而无需依赖启动器或客户端实现。将声明放在各读取方旁边，会使完整配置 API 难以查找，也容易让重叠字段发生偏离。
+
+## 决策
+
+[`@deepseek-ai/dsh-package-manifest`](../../../../packages/util/package-manifest/README.zh.md) 在一个纯类型文件中拥有 `DshManifest` 及其成员声明。本包属于现有工具库分组，不导出运行时值。作者声明与启动器生成的模块后备元数据有明确区分。
+
+各读取方直接导入共享声明。启动器保留 profile 加载、原始 JSON 检查、默认值和解析后的运行时数据。客户端模块保留归一化的启动图。镜像打包器将声明路径解析为目录。Session 目录生成器派生带有已解析导入路径的只读校验结果；原始输入和发现规则仍由本地负责。
+
+App-boot 声明生产依赖，因为其发布的声明文件引用共享类型。客户端模块、私有打包器和根脚本使用开发依赖，因为其发布 API 不暴露这些类型。每个包消费方都有 TypeScript 项目引用。外部作者从工具包导入；app-boot 不提供兼容性再导出。
+
+## 考虑过的替代方案
+
+**将声明保留在各读取方。** 外部作者会依赖运行时实现，而仅覆盖 profile 的部分定义会遗漏已有的客户端和构建字段。
+
+**创建独立的 types 分组。** 现有工具库分组可以容纳纯类型库，无需增加包分类。运行时服务和事件声明仍由各自负责方拥有。
+
+**统一 JSON 解析器。** 共享声明不要求改变校验、错误、默认值或解析结果；这些仍由各读取方负责。
+
+## 后果
+
+作者获得统一的公共导入路径，代价是一个发布包和明确的依赖边。已有的 app-boot manifest 类型导入需要改用新包。[Profile 组合设计](2026-08-05-profile-plugin-bundles.zh.md) 继续负责运行时语义；类型提取不改变配置接受范围或模型可见行为。
+
+编译器与打包后的 NodeNext 消费方检查覆盖公共导入。已有 profile、客户端、镜像配置和 Session 目录测试覆盖读取行为；文档检查覆盖工具库分类与生成的包目录。新增可选声明字段时，仍需主动更新消费方。

 ### Profiles
 
+Import profile and bundle declaration types from [`@deepseek-ai/dsh-package-manifest`](../../util/package-manifest/README.md). App-boot owns profile loading, JSON validation, and resolved runtime data.
+
 A profile is how one dsh installation ships different app surfaces: `web`, `headless`, `acp`, `sdk`, and `sdk-minimal` start distinct compositions from the same launcher. A profile lives at `$DSH_HOME/profiles/<name>` and combines installable bundles, its own `cordis.patch.yml`, and `patchReload: live | startup`; omitted reload policy keeps the historical `live` default for custom profiles. The shipped `web` template uses live reload, while the other shipped templates apply patches only at startup. `sdk-minimal` names only its standalone bundle; the other templates retain base-plus-mode stacks. `dsh plugin` creates custom profiles, and a missing bundle or one without a patch declaration fails startup loudly.

 profile 是同一套 dsh 安装提供不同应用界面的方式：`web`、`headless`、`acp`、`sdk` 与 `sdk-minimal` 从同一 launcher 启动不同组合。profile 位于 `$DSH_HOME/profiles/<name>`，由可安装 bundle、自身 `cordis.patch.yml` 与 `patchReload: live | startup` 组成；自定义 profile 省略 reload 策略时保留历史 `live` 默认值。随产品交付的 `web` 模板实时重载，其他随附模板只在启动时应用 patch。`sdk-minimal` 只列出自身的独立 bundle，其他模板保留 base 加模式 bundle 的栈。`dsh plugin` 创建自定义 profile；缺失 bundle 或未声明 patch 的 bundle 会让启动明确失败。

 ## Use this package
 
+Use [`DshClientManifest`](../../util/package-manifest/README.md) for the declaration type. Client-modules validates the JSON and owns the normalized boot graph.
+
 Use it when you compose or build a browser client plugin: the package turns a package's `dsh.client` declaration into a loadable browser bundle with no per-plugin wiring. It activates with the web composition; the shell boots it before any plugin runs.

 ## Use this package
 
+The [`DshConfigTreeDeclaration`](../../util/package-manifest/README.md) type describes each `dsh.configTrees` entry; this packer validates it and resolves its source directory.
+
 The pack is a three-layer standard stack:
 
 1. **Roster** — the composed profile's plugin rows (standard YAML parse under Include's dialect, `!!js` intact), plus the rows of every config tree the CLI declares in its `package.json` `dsh.configTrees` (agent presets), materialized as a Node-style dependency closure. External peer edges never bind the worker; workspace peers stay on the chain.

+## Summary
+
+Use `DshManifest` to type a package's Harness metadata, or a member type such as `DshClientManifest` for one declaration. Boot, client, build, and external packages import the same types; each reader owns JSON validation and default resolution.

+## Use this package
+
+Import from the package root. Use a development dependency when only checking your own source; use a production dependency if your published declarations reference these types.
+
+```ts
+import type { DshClientManifest, DshManifest } from '@deepseek-ai/dsh-package-manifest'
+
+const client: DshClientManifest = { platform: 'web' }
+const dsh: DshManifest = {
+  bundle: { patch: './cordis.patch.yml' },
+  client,
+}
+```
+
+`DshManifest` describes `bundle`, `profile`, `client`, `configTrees`, `sessionFormatMigration`, and `moduleFallback`, not the surrounding npm manifest. `moduleFallback` is launcher-generated metadata and is not an author configuration entry. TypeScript checks this object and erases `import type` during compilation; JSON files cannot import types, and this example does not write a `package.json`. See [`src/types.ts`](src/types.ts) for the declarations.
+

+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The package root only re-exports declarations from [`src/types.ts`](src/types.ts). It has no runtime state or independently observable relationships, so it publishes no runtime invariant companion.
+
+</details>
+
+-----
+
+<a id="further-exploration"></a>
+## Further Exploration
+
+- [Profile launcher](../../boot/app-boot/README.md#profiles) — manifest loading and composition.
+- [Declaration ownership](../../../.agents/notes/implemented/architecture/2026-09-05-package-manifest-types.md) — scope and dependency rationale.
+
+<a id="model-experience"></a>
+## Model Experience
+
+None, as this package only exports types.
+
+#### KV Cache effect
+
+Type declarations add no model input, so provider cache reuse is unaffected.
+
+## Known Limitations and Deferred Work
+
+<a id="known-limitations-and-deferred-work"></a>
+
+- **Static typing only.** These declarations do not validate JSON, check file existence, or supply defaults. `configTrees` serves the experimental image packer, and `sessionFormatMigration` is discovered only for workspace migration packages; declaring them does not register external plugin behavior.

+## 概述

+## 使用本包
+
+从包根导入类型。仅检查自己的源码时使用开发依赖；若发布的声明文件引用这些类型，则使用生产依赖。
+
+```ts
+import type { DshClientManifest, DshManifest } from '@deepseek-ai/dsh-package-manifest'
+
+const client: DshClientManifest = { platform: 'web' }
+const dsh: DshManifest = {
+  bundle: { patch: './cordis.patch.yml' },
+  client,
+}
+```
+
+`DshManifest` 描述 `bundle`、`profile`、`client`、`configTrees`、`sessionFormatMigration` 和 `moduleFallback`，不包含外层 npm manifest。`moduleFallback` 是启动器生成的元数据，不是作者配置项。TypeScript 检查该对象，并在编译时删除 `import type`；JSON 文件不能导入类型，此示例也不会写入 `package.json`。声明见 [`src/types.ts`](src/types.ts)。
+
+-----
+
+<a id="understand-the-implementation"></a>
+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+包根仅重新导出 [`src/types.ts`](src/types.ts) 中的声明。本包没有运行时状态或可独立观察的关系，因此不发布运行时不变量伴随模块。
+
+</details>
+
+-----
+
+<a id="further-exploration"></a>
+## 进一步探索
+
+- [Profile 启动器](../../boot/app-boot/README.zh.md#profiles)——manifest 加载与组合。
+- [声明归属](../../../.agents/notes/implemented/architecture/2026-09-05-package-manifest-types.zh.md)——范围与依赖依据。
+
+<a id="model-experience"></a>
+## 模型体验
+
+无，因为本包仅导出类型。
+
+#### KV Cache 影响
+
+类型声明不增加模型输入，因此不影响提供方的缓存复用。
+
+## 已知限制与后续工作
+
+<a id="known-limitations-and-deferred-work"></a>
+
+- **仅提供静态类型。** 这些声明不校验 JSON、不检查文件存在性，也不提供默认值。`configTrees` 服务于实验性镜像打包器，`sessionFormatMigration` 仅从工作区迁移包中发现；声明它们不会注册外部插件行为。

+# Agent Note: SDK default file editor selection
+
+Status: implemented
+
+English | [中文](2026-09-05-sdk-default-file-editor.zh.md)
+
+## Problem
+
+The standard SDK profile inherits both `read`/`write`/`edit` and `str_replace_editor` from the shared base. These offer overlapping file editing interfaces, while the Web standard preset selects the former. [Issue #3599](https://github.com/deepseek-harness/deepseek-harness/issues/3599) requests the same editor choice for the standard SDK without making all SDK and Web behavior identical.
+
+## Decision
+
+The [SDK application patch](../../../../packages/bundle/sdk-app/cordis.patch.yml) disables the inherited `tool-str-replace-editor` row. The SDK retains `read`, `write`, and `edit`; the shared base, reusable editor package, and standalone `sdk-minimal` composition retain their own defaults. A trusted profile, home, or invocation patch can explicitly enable the row.
+
+This narrows the SDK tool default described by [one dsh launcher](../architecture/2026-08-22-single-dsh-application-launcher.md). That decision remains active for launch ownership, shared services, and patch precedence; no active note is fully superseded.
+
+## Alternatives considered
+
+**Keep both editors enabled.** Shared base composition explains their availability, but the standard SDK does not need two default interfaces for the same file editing operations. Callers requiring this editor can select it explicitly.
+
+**Remove the shared registration or reuse the entire Web preset.** Either changes more than the requested SDK default. Keeping the change in the SDK bundle preserves other profiles and the existing application architecture.
+
+## Consequences
+
+Default SDK requests omit the editor schema. Callers that select `str_replace_editor` by name need an explicit patch or their existing dedicated composition. This decision makes no claim of complete SDK/Web tool parity.
+
+## Verification
+
+The [SDK profile process test](../../../../apps/cli/tests/profiles/sdk/keyless-smoke.e2e.ts) captures actual model requests for the default roster, explicit editor enablement, and standalone minimal roster. [SDK recorded sessions](../../../../snapshots/sdk/sdk.snapshot.ts) pin the resulting schemas; shared cross-profile and persistent-editor recordings explicitly retain their required editor.

+# Agent Note: SDK 默认文件编辑器选择
+
+Status: implemented
+
+[English](2026-09-05-sdk-default-file-editor.md) | 中文
+
+## Problem
+
+标准 SDK profile 从共享 base 同时继承 `read`/`write`/`edit` 和 `str_replace_editor`。这些工具提供重叠的文件编辑接口，而 Web standard preset 选择前者。[Issue #3599](https://github.com/deepseek-harness/deepseek-harness/issues/3599) 要求标准 SDK 采用相同的编辑器选择，不要求 SDK 与 Web 的全部行为一致。
+
+## Decision
+
+[SDK 应用 patch](../../../../packages/bundle/sdk-app/cordis.patch.yml) 禁用继承的 `tool-str-replace-editor` 配置项。SDK 保留 `read`、`write` 和 `edit`；共享 base、可复用编辑器包及独立 `sdk-minimal` 组合保留各自的默认值。受信任的 profile、home 或逐次调用 patch 可以显式启用该配置项。
+
+本决策收窄了[统一 dsh 启动器](../architecture/2026-08-22-single-dsh-application-launcher.zh.md)所述的 SDK 工具默认值。该决策对启动所有权、共享服务和 patch 优先级仍然有效；没有被完全取代的活跃 Agent Note。
+
+## Alternatives considered
+
+**继续默认启用两个编辑器。** 共享 base 组合解释了它们为何可用，但标准 SDK 无需为相同的文件编辑操作默认提供两套接口。需要此编辑器的调用方可以显式选择它。
+
+**移除共享注册或复用整个 Web preset。** 两者都会扩大 SDK 默认值调整的范围。将改动放在 SDK bundle 中可以保留其他 profile 和现有应用架构。
+
+## Consequences
+
+默认 SDK 请求省略该编辑器 schema。按名称选择 `str_replace_editor` 的调用方需要显式 patch 或其现有专用组合。本决策不承诺 SDK/Web 的全部工具一致。
+
+## Verification
+
+[SDK profile 进程测试](../../../../apps/cli/tests/profiles/sdk/keyless-smoke.e2e.ts) 捕获默认工具清单、显式启用编辑器和独立极简工具清单的实际模型请求。[SDK 录制会话](../../../../snapshots/sdk/sdk.snapshot.ts) 固定最终 schema；跨 profile 共享录制与持久编辑器录制显式保留其所需的编辑器。

+# Agent Note: pi-ai upgrade compatibility
+
+Status: implemented

+
+## Problem
+
+The pi-ai adapter classifies upstream compatibility fields explicitly and persists only replay metadata needed by later requests. An SDK upgrade can add fields to either set without changing the Harness provider-neutral API. Unclassified configuration fields fail compilation; omitted replay metadata can silently change subsequent provider requests.
+
+## Decision
+
+The adapter follows [pi-ai 0.85.1](https://github.com/earendil-works/pi/blob/v0.85.1/packages/ai/CHANGELOG.md). `thinkingTokenBudgetField`, `vllmPriority`, and `supportsMaxOutputTokens` are opt-in gateway controls; `thinking.budget` joins the existing template placeholders. The SDK owns budget resolution and serialization. `supportsMidConvoEffort` and `allowedFallbackModels` remain catalog-owned because their correctness depends on exact Anthropic transports, model capabilities, and fallback pricing.
+
+Optional `providerThinkingLevel` remains in the adapter replay-v2 response metadata so Anthropic history retains its provider-native effort. Absence remains valid; neither the replay version nor the released Session format changes. The provider-neutral LLM API stays unchanged.
+
+## Alternatives considered
+
+**Withhold every new field.** This would misclassify deployment-owned gateway controls as catalog facts: upstream explicitly leaves budget-field selection and vLLM priority out of its generated catalog.
+
+**Expose every new field.** This would let arbitrary gateways claim model-specific Anthropic effort and fallback support without the catalog evidence that makes those features valid.
+
+## Consequences
+
+Compile-time coverage retains explicit field classification. [Compatibility tests](../../../../packages/llm/llm-pi-ai/tests/compat-upgrade.spec.ts) cover schema acceptance, invalid values, protocol applicability, and materialization without changing defaults. [Replay conversion tests](../../../../packages/llm/llm-pi-ai/tests/convert.spec.ts) cover optional effort preservation. Mixed-protocol catalog tests use the installed OpenCode catalog. Provider behavior remains upstream-owned; live provider verification is separate from keyless adapter tests.

+# Agent Note: pi-ai 升级兼容性
+
+Status: implemented
+
+[English](2026-09-05-pi-ai-upgrade-compatibility.md) | 中文
+
+## Problem
+
+pi-ai 适配器显式分类上游兼容字段，并且只持久化后续请求需要的回放元数据。SDK 升级可能在不改变 Harness 提供方无关 API 的情况下为任一集合新增字段。未分类的配置字段会导致编译失败；遗漏回放元数据则可能静默改变后续提供方请求。
+
+## Decision
+
+适配器遵循 [pi-ai 0.85.1](https://github.com/earendil-works/pi/blob/v0.85.1/packages/ai/CHANGELOG.md)。`thinkingTokenBudgetField`、`vllmPriority` 和 `supportsMaxOutputTokens` 是显式启用的网关控制；`thinking.budget` 加入现有模板占位符。SDK 拥有预算解析和序列化。`supportsMidConvoEffort` 和 `allowedFallbackModels` 仍由目录拥有，因为其正确性依赖确切的 Anthropic 传输、模型能力和回退定价。
+
+可选的 `providerThinkingLevel` 保存在适配器 replay-v2 响应元数据中，让 Anthropic 历史保留提供方原生 effort。缺失仍然有效；回放版本与已发布 Session 格式均不改变。提供方无关的 LLM API 保持不变。
+
+## Alternatives considered
+
+**保留所有新增字段为不可配置。** 这会把部署拥有的网关控制误分类为目录事实：上游明确不在生成目录中设置预算字段选择和 vLLM 优先级。
+
+**开放所有新增字段。** 这会允许任意网关在缺少目录证据时声明支持模型专属的 Anthropic effort 与回退能力，而这些证据正是相关功能有效的依据。
+
+## Consequences
+
+编译期覆盖保留显式字段分类。[兼容性测试](../../../../packages/llm/llm-pi-ai/tests/compat-upgrade.spec.ts) 覆盖 schema 接受、无效值、协议适用范围及物化，且不改变默认值。[回放转换测试](../../../../packages/llm/llm-pi-ai/tests/convert.spec.ts) 覆盖可选 effort 的保留。混合协议目录测试使用已安装的 OpenCode 目录。提供方行为仍由上游拥有；真实提供方验证与无需密钥的适配器测试分开。

 `reasoningEfforts` declares a model's selectable thinking levels: each key is a level selectors offer, its value the spelling dispatch sends on the wire, so `max: ultra` renames a level for a gateway with its own vocabulary. Omitting the field keeps the installed catalog entry's capability; `false` declares a non-reasoning model. `compat` switches reshape the request for endpoints pi-ai cannot recognize — which role carries the system prompt, which field caps output, how a thinking level travels — configurable per route and per model. A model neither the entry nor the installed catalog sizes takes the route's `defaultContextWindow` and `defaultMaxTokens` fallbacks.
 
+For self-hosted Chat Completions endpoints, `thinkingTokenBudgetField` selects the reasoning-budget parameter, and `vllmPriority` sets an integer scheduler priority when the server enables priority scheduling. Template arguments accept `$var: thinking.budget`. Responses gateways can set `supportsMaxOutputTokens: false` to omit `max_output_tokens`. These controls are opt-in; catalog-owned Anthropic effort and fallback capabilities are not configurable switches.

 ### Change configuration at runtime
 
 Profiles are re-read once per operation through the optional settings seam: the base and the user's `llm-pi-ai:` settings section merge per provider, so a user can add a route, override one field of a composition route, or point a route at another proxy, all effective on the next request with no restart. A section the adapter could not serve is refused where it is written — `settings.mutate` answers `settings-rejected` — and a stored section that later fails keeps the namespace's last good value. When the route set or a route's retry policy changes, the plugin re-registers atomically: a conflicting route leaves the previous routes serving.

-Successful assistant responses store a versioned, lossless-JSON replay state beside the provider and model that produced them — response-level facts plus one per-block entry per streamed block.

 The adapter follows [pi-ai 0.85.1](https://github.com/earendil-works/pi/blob/v0.85.1/packages/ai/CHANGELOG.md). `thinkingTokenBudgetField`, `vllmPriority`, and `supportsMaxOutputTokens` are opt-in gateway controls; `thinking.budget` joins the existing template placeholders. The SDK owns budget resolution and serialization. `supportsMidConvoEffort` and `allowedFallbackModels` remain catalog-owned because their correctness depends on exact Anthropic transports, model capabilities, and fallback pricing.

+Optional `providerThinkingLevel` remains in the adapter replay-v2 response metadata so Anthropic history retains its provider-native effort. Absence remains valid; neither the replay version nor the released Session format changes. Replay provenance retains the requested model while `responseModel` retains an Anthropic alias resolution or fallback. Reconstruction restores that native model so pi-ai still applies its cross-model signature rules. The provider-neutral LLM API stays unchanged.

Omitting the field keeps the installed catalog entry's capability; `false` declares a non-reasoning model. `compat` switches reshape the request for endpoints pi-ai cannot recognize — which role carries the system prompt, which field caps output, how a thinking level travels — configurable per route and per model.

 A terminal successful `finish` chunk may carry replay state as a `ReplayEnvelope`: opaque response-level metadata plus optional per-block entries aligned with the emitted block sequence. `BlockAssembler` makes one keep/drop decision for content and metadata — when max-token assembly drops a tool call, the envelope loses the entry at the same position — so the state the loop attaches to the assembled assistant message's model source always describes the stored blocks, per the [max-token replay-state alignment decision](../../archived/bug-fix/2026-08-15-max-token-replay-state-alignment.md). The loop exposes no response-rewrite hook. Error and aborted responses do not produce a normal assistant message and therefore do not enter future model history.
 
-The pi-ai replay state fills that envelope with a versioned, minimal projection of its successful `AssistantMessage`: a response half (source API/provider/model, response id/model, stop reason) and per-block text, thinking, and tool-call signatures. It does not duplicate text or tool arguments already carried by Harness content blocks, and it omits diagnostics, timestamps, usage, and errors. On a later request, `LlmRuntime` gives replay state to the target adapter only when the historical provider and target provider are currently owned by the same adapter instance. That adapter combines the logged Harness content with replay state when it can restore the historical response, and owns any required cross-model or cross-provider conversion. Durable content stays authoritative: an adapter receiving replay state it cannot use — an unknown kind or version, malformed metadata, or a block shape that no longer matches the content — degrades that message to provider-neutral conversion with a diagnostic; a different adapter receives only provider-neutral content plus provider/model fields.

 This state is model-visible replay input and therefore follows the existing [reconstructable-request rule](2026-07-05-reconstructable-requests.md): it is present in both the terminal `finish` chunk and the assembled `assistant/message` model source that drives derivation. Resume and fork preserve it verbatim. Compaction that shadows the assistant message also removes its replay state from the active surface; the summary is ordinary provider-neutral content.

 The adapter follows [pi-ai 0.85.1](https://github.com/earendil-works/pi/blob/v0.85.1/packages/ai/CHANGELOG.md). `thinkingTokenBudgetField`, `vllmPriority`, and `supportsMaxOutputTokens` are opt-in gateway controls; `thinking.budget` joins the existing template placeholders. The SDK owns budget resolution and serialization. `supportsMidConvoEffort` and `allowedFallbackModels` remain catalog-owned because their correctness depends on exact Anthropic transports, model capabilities, and fallback pricing.

Absence remains valid; neither the replay version nor the released Session format changes. Replay provenance retains the requested model while `responseModel` retains an Anthropic alias resolution or fallback. Reconstruction restores that native model so pi-ai still applies its cross-model signature rules. The provider-neutral LLM API stays unchanged.

+# Agent Note: Canonical feedback log and request delivery
+
+Status: implemented
+
+English | [中文](2026-09-05-canonical-feedback-log.zh.md)
+
+## Problem
+
+Editable message ratings need one durable authority that Session export and request delivery can retain. A separate feedback store makes those consumers incomplete and introduces a second commit relationship with the target message. Recording a human judgment must not change model input or imply that a collector accepted it.
+
+## Decision
+
+The canonical Session log owns feedback. Session-level remarks use `feedback/record`; material message edits and deletions use `feedback/message-put` and `feedback/message-delete`. All are log-only. The service folds current items from events matching the requested `sessionId`, so inherited parent events do not become a fork's current feedback. Deletion removes the current item, not earlier ratings or notes from the log.
+
+Live message-feedback mutations append through the owning Session and await its durability checkpoint; cold mutations hold a persistence write handle across read, comparison, append, and flush without creating a Session or Agent. A matching no-op appends nothing but still awaits persistence. Failures propagate, and a failed live flush can leave an observable in-memory item for retry. Per-item versions prevent unrelated message edits from conflicting; strict stale-write rejection prevents ABA overwrites even when the desired value matches. Target validation binds a judgment to a sent assistant message, and forks keep independent judgments. These choices retain rationale recorded in the [archived sidecar decision](../../archived/architecture/2026-08-10-message-feedback-sidecar.md), whose storage and commit mechanism is superseded.
+
+The existing opt-in [session-log-deepseek contribution](../../../../packages/session/session-log-deepseek/README.md) includes feedback in the ordinary `dsh_session_log` suffix on a subsequent eligible request. It uses the existing DeepSeek destination selection and acceptance watermark. There is no separate `dsh_feedback` uploader, feedback-triggered request, or model-input field. The shipped base disables its OTel row; this supersedes the default composition in the [feedback-gated default decision](../feature/2026-08-25-feedback-gated-telemetry-default.md), not the optional backend's modes.
+
+The command confirms recording with the Session and anonymous user ids, without depending on telemetry or disclosing its policy. Its append remains unflushed. This supersedes the command-copy decision in the [archived sharing disclosure note](../../archived/feature/2026-08-07-feedback-acknowledgement-sharing-disclosure.md). The [telemetry service's policy API](../../../../packages/session/session-telemetry/README.md#the-sharing-disclosure) remains independently available: a backend discloses its policy, not delivery or retention, and the optional OTel package does not own that vocabulary.
+
+## Alternatives considered
+
+**Keep the sidecar.** It supports destructive local edits, but cannot make feedback part of ordinary canonical-log export and delivery without another join and durability relationship.
+
+**Reuse `feedback/record` for message edits.** A free-text Session remark does not identify an item mutation, and its optional OTel consumer treats it as a release trigger. Distinct events preserve message identity and deletion semantics without that coupling.
+
+**Add a dedicated uploader or immediate request.** The existing opt-in log contribution already carries canonical events and records acceptance. A second path would add delivery ownership and deduplication policy; this design accepts delayed delivery instead.
+
+## Consequences
+
+Feedback survives ordinary log export and replay without consuming model-input tokens or changing KV Cache. Current-item deletion is not erasure, and feedback recorded after the last eligible request can remain local indefinitely. The Web controller remains a unary Remote consumer and does not consume feedback log events for cross-tab updates.
+
+[Message-feedback tests](../../../../packages/feedback/message-feedback/tests/message-feedback.spec.ts) cover material events, no-ops, strict versions, fork isolation, and persistence failures. The [request contribution tests](../../../../packages/session/session-log-deepseek/tests) own suffix acceptance and retry; the [command tests](../../../../packages/feedback/command-feedback/tests/command-feedback.spec.ts) pin the plain confirmation.

+# Agent Note: 权威反馈日志与请求投递
+
+Status: implemented
+
+[English](2026-09-05-canonical-feedback-log.md) | 中文
+
+## 问题
+
+可编辑的消息评分需要一个能由 Session 导出与请求投递保留的持久权威来源。独立的反馈存储会让这些消费方拿到不完整的数据，并引入与目标消息之间的第二套提交关系。记录人类判断不能改变模型输入，也不能暗示采集端已经接受数据。
+
+## 决策
+
+权威 Session 日志拥有反馈。Session 级备注使用 `feedback/record`；消息的实质编辑与删除使用 `feedback/message-put` 和 `feedback/message-delete`。三者都仅写日志。服务从与请求的 `sessionId` 匹配的事件中归约当前条目，因此继承的父级事件不会成为 fork 的当前反馈。删除会移除当前条目，但不会抹除日志中早先的评分或备注。
+
+live 消息反馈变更通过所属 Session 追加，并等待其持久化检查点；cold 变更在读取、比较、追加和 flush 期间持有持久化写句柄，不创建 Session 或 Agent。匹配版本的无变更操作不追加事件，但仍等待持久化。故障会原样传播，live flush 失败可能留下可观测的内存条目以供重试。逐条版本避免不同消息的编辑互相冲突；严格拒绝陈旧写入避免 ABA 覆盖，即使期望值已经匹配也不例外。目标校验把判断绑定到已发送的 assistant 消息，fork 保持独立判断。这些选择保留[已归档伴随记录决策](../../archived/architecture/2026-08-10-message-feedback-sidecar.md)记载的理由，但其存储与提交机制已被取代。
+
+现有需显式启用的 [session-log-deepseek 贡献](../../../../packages/session/session-log-deepseek/README.zh.md)会在后续符合条件的请求中，把反馈纳入普通 `dsh_session_log` 后缀。它使用现有的 DeepSeek 目标选择和接受水位。没有独立的 `dsh_feedback` 上传器、反馈触发的请求或模型输入字段。随附基础配置禁用 OTel 配置行；这取代[反馈门控默认值决策](../feature/2026-08-25-feedback-gated-telemetry-default.zh.md)中的默认组合，不改变可选后端的模式。
+
+命令用 Session 与匿名用户 id 确认记录，不依赖遥测，也不披露其策略。其追加仍不执行 flush。这取代[已归档共享披露记录](../../archived/feature/2026-08-07-feedback-acknowledgement-sharing-disclosure.md)中的命令文案决策。[遥测服务的策略 API](../../../../packages/session/session-telemetry/README.zh.md#the-sharing-disclosure) 仍可独立使用：后端披露策略，而不保证投递或保留，可选 OTel 包不拥有这套词汇。
+
+## 考虑过的替代方案
+
+**保留伴随记录。** 它支持破坏性的本地编辑，但若不增加关联读取及持久化关系，就无法让反馈参与普通权威日志导出与投递。
+
+**对消息编辑复用 `feedback/record`。** 自由文本的 Session 备注不能标识条目变更，其可选 OTel 消费方还会将它当作释放触发器。独立事件保留消息身份和删除语义，不引入该耦合。
+
+**增加专用上传器或立即发起请求。** 现有需显式启用的日志贡献已经传送权威事件并记录接受结果。第二条路径会增加投递归属与去重策略；本设计接受延迟投递。
+
+## 后果
+
+反馈随普通日志导出与回放保留，不消耗模型输入 token，也不改变 KV Cache。删除当前条目不等于抹除历史，最后一次符合条件的请求之后记录的反馈可能无限期保留在本地。Web 控制器仍消费一元 Remote，不消费反馈日志事件来更新其他标签页。
+
+[消息反馈测试](../../../../packages/feedback/message-feedback/tests/message-feedback.spec.ts)覆盖实质事件、无变更操作、严格版本、fork 隔离与持久化故障。[请求贡献测试](../../../../packages/session/session-log-deepseek/tests)负责后缀接受与重试；[命令测试](../../../../packages/feedback/command-feedback/tests/command-feedback.spec.ts)固定纯确认文本。

 ## Decision
 
-The shared dsh base resolves an unset or empty `DSH_TELEMETRY_MODE` to `FEEDBACK_ONLY` instead of `DISABLED`. Nothing is uploaded before the user records `/feedback`. On a Session object already captured, each feedback uploads the suffix after the last handoff through that exact event. A new object starts at its constructor boundary: a fresh Session begins at seq 0, while a forked, resumed, or migrated Session excludes its constructor seed and begins with this lifecycle's `session/end-seed`. The acknowledgement's sharing disclosure therefore matches the released lifecycle-local prefix. `FULL` and `DISABLED` remain explicit `DSH_TELEMETRY_MODE` overrides, any non-empty `DSH_TELEMETRY_DISABLED` remains the authoritative pre-load hard opt-out, and the plugin's own omitted-`mode` default stays `DISABLED`: the default changes only in the shared base's config expression, where deployments already override it.
+The [canonical feedback decision](../architecture/2026-09-05-canonical-feedback-log.md) supersedes this default composition: the shipped base disables its OTel row. The optional backend retains its modes; the release-boundary rationale below does not authorize upload in a default installation.
 
-This supersedes the session-backend default of the [default-off decision](../../archived/feature/2026-08-10-telemetry-default-off.md), accepting the user's explicit feedback action as the release authorization that note required a deployment setting for. That note's hard opt-out and its launcher-feed history remain current, and the [default-mount decision](../../archived/feature/2026-07-31-web-telemetry-default-mount.md) continues to own the endpoint, batching cadence, and exit-drain settings.
+When explicitly enabled without replacing its config, the shared base's OTel row resolves an unset or empty `DSH_TELEMETRY_MODE` to `FEEDBACK_ONLY`. The plugin's own omitted-`mode` default remains `DISABLED`; `FULL` and `DISABLED` are explicit environment overrides, and non-empty `DSH_TELEMETRY_DISABLED` remains the pre-load hard opt-out. In `FEEDBACK_ONLY`, each `feedback/record` releases the canonical suffix after the same Session object's handoff cursor through that event. A new object starts at its constructor boundary: a fresh Session begins at seq 0, while a forked, resumed, or migrated Session excludes its constructor seed and begins with this lifecycle's `session/end-seed`.
+
+Feedback-gated release lets a reporter share the lifecycle that exhibited the problem without reproducing it. It trades continuous export for an explicit feedback trigger, but a deployment must establish consent before enabling that policy. The [archived default-off](../../archived/feature/2026-08-10-telemetry-default-off.md) and [default-mount](../../archived/feature/2026-07-31-web-telemetry-default-mount.md) notes record the earlier composition; the [base patch](../../../../packages/bundle/base/cordis.patch.yml) and [OTel README](../../../../packages/session/session-telemetry-otel/README.md) own current configuration.
 
 ## Alternatives considered
 
-**Keep `DISABLED` and instruct reporters to re-run with `DSH_TELEMETRY_MODE=FEEDBACK_ONLY`.** Rejected: the session that exhibited the problem is the one worth uploading, and re-running loses it.
+**Require reporters to re-run after enabling telemetry.** Rejected as the feedback-gated workflow: the Session that exhibited the problem is the useful evidence, and re-running loses it.
 
-**Default to `FULL`.** Rejected: continuous export without any user action is exactly what the default-off decision forbids, and nothing in a fresh installation authorizes it.
+**Default to `FULL`.** Rejected: a fresh installation does not authorize continuous export without user action.
 
-**Gate the official DeepSeek `dsh_session_log` request contribution on feedback instead of reviving the OTel default.** Not taken here: that contribution uploads through subsequent LLM requests rather than at the feedback boundary, so a session's final feedback would never be delivered; a feedback-triggered flush on that path is a larger design than a default flip.
+**Use only subsequent DeepSeek requests for delivery.** The canonical feedback decision accepts this for the shipped default, including the risk that a final feedback entry remains local. The optional feedback-gated OTel mode retains its event-time release trigger; request-time delivery cannot provide that timing without initiating another request.
 
 ## Consequences
 
-- A fresh installation uploads the not-yet-shared session-log records to the production collector when — and only when — the user records `/feedback`; no other trigger uploads.
-- Released exports remain the raw captured copy: the shipped base mounts no `session-telemetry/record` redaction rule, so they can contain message text, tool arguments and results, and workspace paths.
-- The sharing disclosure is part of the `/feedback` acknowledgement, so the user reads it after the release has been triggered. A deployment that requires prior informed consent must override the default to `DISABLED` or add a pre-upload confirmation before this default is defensible there.
+- The shipped base uploads nothing through OTel. An explicitly enabled `FEEDBACK_ONLY` backend hands off the unreleased lifecycle-local prefix only on `feedback/record`; message-rating events do not themselves trigger release.
+- On-demand capture copies and redacts the canonical log at feedback time. Without a deployment redaction rule, exported data can include message text, tool arguments and results, and workspace paths.
+- The command acknowledgement confirms recording, not sharing or delivery. A deployment requiring prior informed consent must provide it before enabling uploads; OTel handoff remains subject to the SDK's batching, retry, and loss policy.

+反馈门控释放让报告者无需复现问题就能共享出问题的生命周期。它用显式反馈触发取代持续导出，但部署必须在启用该策略前取得同意。[已归档默认关闭](../../archived/feature/2026-08-10-telemetry-default-off.md)与[默认挂载](../../archived/feature/2026-07-31-web-telemetry-default-mount.md)记录记载早期组合；当前配置由[基础补丁](../../../../packages/bundle/base/cordis.patch.yml)与 [OTel README](../../../../packages/session/session-telemetry-otel/README.zh.md) 持有。
 
 ## 考虑过的替代方案
 
-**保持 `DISABLED`，让报告者带着 `DSH_TELEMETRY_MODE=FEEDBACK_ONLY` 重跑。** 否决：值得上传的正是出现问题的那个会话，重跑会丢掉它。
+**要求报告者启用遥测后重跑。** 不作为反馈门控工作流：值得保留的证据是出问题的那个 Session，重跑会丢掉它。
 
-**默认 `FULL`。** 否决：没有任何用户动作的持续导出正是默认关闭决定所禁止的，全新安装中没有任何东西授权它。
+**默认 `FULL`。** 否决：全新安装不授权没有用户动作的持续导出。
 
-**改为在反馈时门控官方 DeepSeek `dsh_session_log` 请求贡献，而不是恢复 OTel 默认值。** 此处未采用：该贡献通过后续 LLM 请求上传，而不是在反馈边界上传，会话的最后一条反馈永远不会被交付；在那条路径上做反馈触发的冲刷是比翻转默认值更大的设计。
+**仅通过后续 DeepSeek 请求投递。** 权威反馈决策为随附默认配置接受此方案，包括最后一条反馈可能留在本地的风险。可选反馈门控 OTel 模式保留事件发生时的释放触发；请求时投递若不发起另一个请求，就无法提供这种时机。
 
 ## 后果
 
-- 全新安装只在用户记录 `/feedback` 时把尚未共享的会话日志记录上传到生产 collector；没有其他触发上传的途径。
-- 释放的导出仍是未加工的原始副本：随附基础配置没有挂载 `session-telemetry/record` 脱敏规则，导出可能包含消息文本、工具参数和结果，以及 workspace 路径。
-- 共享声明是 `/feedback` 确认信息的一部分，用户读到它时释放已被触发。要求事先知情同意的部署必须把默认值覆盖为 `DISABLED`，或在上传前增加确认步骤，此默认值在那类部署中才站得住。
+- 随附基础配置不通过 OTel 上传任何内容。显式启用的 `FEEDBACK_ONLY` 后端只在 `feedback/record` 时交接未释放的生命周期本地前缀；消息评分事件本身不触发释放。
+- 按需捕获在反馈时复制权威日志并脱敏。部署未挂载脱敏规则时，导出数据可能包含消息文本、工具参数和结果，以及 workspace 路径。
+- 命令确认文本确认记录，而非共享或投递。要求事先知情同意的部署必须在启用上传前提供该步骤；OTel 交接仍受 SDK 的批处理、重试与丢失策略约束。

 ## Shared deployment behavior
 
-The base bundle mounts the native DeepSeek adapter, settings and credential providers, stable `web_search` and `web_fetch`, the public-only HTTP fetch provider, and feedback-gated session telemetry. Provider credentials resolve from the inherited environment, `$DSH_HOME/.credentials.yaml`, the invoking directory's `.env`, then `$DSH_HOME/.env`; the managed document is never materialized into `process.env`, while both `.env` files are ordinary launch environment layers. Search uses `DEEPSEEK_API_KEY` and accepts `DEEPSEEK_SEARCH_BASE_URL`. Enabled fetch calls run in every sandbox and approval mode without per-call confirmation; the provider rejects non-public destinations before connecting. The Web app disables the base tool row and exposes the same tools through its `cordis`, `ptc`, and `standard` agent presets.
+The base bundle mounts the native DeepSeek adapter, settings and credential providers, stable `web_search` and `web_fetch`, the public-only HTTP fetch provider, and opt-in DeepSeek session-log upload.

The Web app disables the base tool row and exposes the same tools through its `cordis`, `ptc`, and `standard` agent presets.
 
-Session telemetry defaults to feedback-gated sharing: nothing is uploaded until the user records `/feedback`, and each recorded feedback uploads the session records not yet shared, through that event; a resumed session shares only its current lifecycle. `DSH_TELEMETRY_MODE=FULL` instead streams every projected session event as OTLP/HTTP logs, `DSH_TELEMETRY_MODE=DISABLED` keeps everything local, and any non-empty `DSH_TELEMETRY_DISABLED` remains an authoritative hard opt-out. `DSH_TELEMETRY_OTLP_URL` selects another collector. The shipped base has no telemetry redaction rule, so released exports can contain message text, tool arguments and results, and workspace paths; the [feedback-gated-default Agent Note](../../../.agents/notes/implemented/feature/2026-08-25-feedback-gated-telemetry-default.md) owns that deployment decision.
+Feedback is recorded in the Session log without starting model work. Enable the [DeepSeek session-log contributor](../../../packages/session/session-log-deepseek/README.md) to send complete unaccepted log suffixes with subsequent DeepSeek requests, including configured gateways. The shipped OTel session-upload row is disabled; changing `DSH_TELEMETRY_MODE` alone does not enable it. Session-log upload can include message text, tool arguments and results, and workspace paths.
 
 Install external plugin bundles through `dsh plugin --profile <name> add <package-or-git-spec>`. The installed package owns its dependencies and contributes its declared `cordis.patch.yml` layer. The CLI also ships `@deepseek-ai/dsh-mcp-client` as a dependency for patch layers, but no MCP server is enabled by default because each server command is trusted executable code outside the agent sandbox.

-会话遥测默认按反馈门控共享：在用户记录 `/feedback` 之前不上传任何数据，每条已记录的反馈通过该事件上传尚未共享的会话记录；恢复的会话只共享当前生命周期。`DSH_TELEMETRY_MODE=FULL` 改为将每条已投影会话事件作为 OTLP/HTTP 日志流式发送，`DSH_TELEMETRY_MODE=DISABLED` 让全部数据留在本地，任何非空的 `DSH_TELEMETRY_DISABLED` 仍是具有最终效力的遥测强制关闭开关。`DSH_TELEMETRY_OTLP_URL` 选择其他 collector。随附基础配置没有遥测脱敏规则，因此释放的导出可能包含消息文本、工具参数和结果，以及 workspace 路径；相关部署决策见[反馈门控默认值 Agent Note](../../../.agents/notes/implemented/feature/2026-08-25-feedback-gated-telemetry-default.zh.md)。
+反馈记录在会话日志中，不会启动模型工作。开启 [DeepSeek 会话日志贡献器](../../../packages/session/session-log-deepseek/README.zh.md)后，后续 DeepSeek 请求会发送尚未确认的完整日志后缀，包括发往配置网关的请求。随附 OTel 会话上传行处于禁用状态；仅修改 `DSH_TELEMETRY_MODE` 不会启用该行。会话日志上传可能包含消息文本、工具参数和结果，以及工作区路径。
 
 通过 `dsh plugin --profile <name> add <package-or-git-spec>` 安装外部插件组合包。安装的包拥有其依赖，并贡献其声明的 `cordis.patch.yml` 层。CLI 还随附 `@deepseek-ai/dsh-mcp-client` 作为供 patch 层使用的依赖，但默认不启用 MCP 服务器，因为每条服务器命令都是 agent（智能体）沙箱之外的受信任可执行代码。

 ## Data and concurrency
 
-One Session sidecar row contains its header identity `{createdAt, cwd}` and feedback items keyed by `MessageId`. Each item carries a positive or negative rating, an optional note, Host-assigned `createdAt`/`updatedAt` timestamps, and its own opaque version. Versions are compared only for equality and only against the addressed message; callers do not order or synthesize them.
+Current items are folded from canonical feedback events whose payload `sessionId` matches the owning Session. Each item carries a positive or negative rating, an optional note, Host-assigned `createdAt`/`updatedAt` timestamps, and its own opaque version. Versions are compared only for equality and only against the addressed message; callers do not order or synthesize them.
 
-`put` uses strict optimistic concurrency: every request for an existing item must match its current `ifVersion`, including a no-op. A conflict returns the authoritative current item (or `null`), so a caller can reconcile a lost response or a concurrent edit without another read. Deleting an already absent item succeeds. A per-Session queue encloses inspection, read, conflict evaluation, and whole-row write, so these guarantees cover concurrent calls in one Host process.
+`put` uses strict optimistic concurrency: every request for an existing item must match its current `ifVersion`, including a no-op. A conflict returns the authoritative current item (or `null`), so a caller can reconcile a lost response or a concurrent edit without another read. Deleting an already absent item succeeds. A per-Session queue serializes reads and mutations; cold mutations hold a persistence write handle across read, comparison, append, and flush. Matching no-ops append no event.
 
 ## Target and lifecycle authority
 
-A live owner's in-memory log supplies the target Session observation directly; a cold target is read through a `SessionPersistence.open(id, 'read')` handle without publishing or resuming an Agent and without writing recovery. A `stat(id)` preflight classifies definite absence; a read failure for a Session `stat` confirmed propagates as infrastructure failure. `put` accepts only a non-empty, append-origin `assistant/message` with the requested `MessageId`; replacement-origin, usage-only empty, and non-assistant records are not feedback targets.
+A live owner's in-memory log supplies the target Session observation directly; cold reads use a `SessionPersistence.open(id, 'read')` handle, while mutations use a write handle. Neither path constructs a Session or Agent. A `stat(id)` preflight classifies definite absence; a read failure for a Session `stat` confirmed propagates as infrastructure failure. `put` accepts only a non-empty, append-origin `assistant/message` with the requested `MessageId`; replacement-origin, usage-only empty, and non-assistant records are not feedback targets.
 
-The stored `{createdAt, cwd}` identity must match the inspected header. A mismatch is treated as absence: `list` returns no items, while `put` may replace the stale row with one bound to the current header identity. Forks use a new Session identity and receive no sidecar copy even when their seed contains the same messages.
+Fork seeds can contain parent feedback events, but their payload retains the parent `sessionId`, so they do not become current feedback for the child. Deleting an item appends a tombstone; earlier ratings and notes remain in the log.
 
 ## Persistence and Remote contract
 
-The service stores whole Session rows in the `message_feedback` storage domain through `ctx.storageDomain`. Before `put` commits a row that references a target message, a matching live target passes through the canonical `ctx.sessions.flush` checkpoint; both live and cold paths are then physically read from sequence zero through a fresh read handle, which observes at least the flushed prefix by the seam's freshness guarantee. The resulting observation is revalidated before the sidecar write, so the durable target log always precedes its sidecar commit. `maxNoteBytes` is required and bounds note text by UTF-8 bytes; the Web Host composition sets `8192`. The package publishes the Host `messageFeedback.list`, `messageFeedback.put`, and `messageFeedback.delete` unary Remote contract through `TypertRemoteService` and `@Remote`; the generated Cordis API below is the method-level authority.
+Successful message-feedback mutations await canonical persistence: live operations append through the owning Session and require a participating `ctx.sessions.flush` listener; cold operations append and flush through their write handle.

 ## Boundaries and limitations
 
-- The mutation queue is process-local. Storage-domain has no cross-process conditional write, so multiple Host writers to one storage root have no compare-and-swap or lost-update guarantee.
-- Session persistence has no durable deletion API. The service does not treat `session/disposed` or `api-session/removed` as deletion and therefore performs no fake cascade; orphan sidecar rows may remain after out-of-band log removal.
+- The operation queue is process-local; cold writer exclusion relies on the selected persistence provider.
+- Deletion removes the current item, not earlier note text from the append-only log or an already delivered suffix.
 - A request in the narrow interval after live detach but before the persistence catalog materializes the header can receive `session-not-found`; callers retry after retirement materialization.
-- Cold requests scan the complete Session snapshot catalog because persistence has no lookup-by-id metadata operation. One Session row also has no item-count or aggregate-byte cap; `maxNoteBytes` bounds only each note until a concrete consumer owns a row policy.
-- Header identity detects a reused id only when `{createdAt, cwd}` differs; a cloned log retaining the same header identity is indistinguishable by this contract.
+- Cold requests read the complete log; the service has no item-count or aggregate-byte cap. `maxNoteBytes` bounds only each note.
 - The Host contract records no authenticated actor or audit identity and therefore assumes a trusted caller boundary.
 - The Web controls appear in the chat view only. The trajectory and waterfall views render no feedback entry even though their assistant nodes carry the same `messageId`.
-- The sidecar publishes no live frames, so a second tab's rating becomes visible on reconnect or on the next conflict reply rather than immediately.
+- The Web controller does not consume feedback log events, so a second tab's rating becomes visible on reconnect or on the next conflict reply rather than immediately.
 - The note editor does not pre-check `maxNoteBytes`; an oversized note fails on save with `note-too-large` rather than while typing.

The opt-in [DeepSeek session-log contributor](../../session/session-log-deepseek/README.md) carries it with model requests; the OTel session-upload row is disabled.

 ## Summary
 
-This package adds per-message feedback to the Web GUI: a Like/Dislike pair plus an optional note, contributed as the `feedback` entry of the finalized assistant message's action strip. It renders on the closing assistant message of each turn — earlier steps of a multi-step turn produce tool rows rather than a rateable body. One controller per Session backs every message control in that Session, so a single list read seeds the whole transcript. Feedback is a sidecar: ratings and notes never enter the session log, the model context, or telemetry.

 ## Summary
 
-`dsh-command-feedback` lets a user tell the harness what they think of a session: type `/feedback` plus a remark, and the remark is recorded and acknowledged. Recording is immediate and never starts model work, so it is safe at any point in a conversation — the model neither sees the remark nor is interrupted by it. The acknowledgement names the session and the anonymous user, and reports how the session is shared under the deployment's telemetry policy. The command ships with the Web client and needs no configuration; headless, ACP, and JSON-RPC entry points do not provide slash commands and cannot run it.

 ### Design concept
 
-The remark is one append-only fact in the session log, owned by the event rather than by the command that produced it: feedback can arrive from any trigger, so the fact must not depend on the slash command. The command keeps its own bookkeeping payload-free, so the remark text exists in exactly one place in the log, and the event never surfaces to the model. The sharing disclosure reads the optional telemetry service through the plugin context, so the command still works when no backend is mounted, and its sentence set mirrors the telemetry status union so an unknown status fails closed.

 ## Summary
 
-`dsh-message-feedback` lets product surfaces offer per-message feedback: a user marks an assistant message positive or negative and can attach a short note, and the rating stays with that message. Ratings are stored with the session, survive restarts, and never enter model history or telemetry. Product surfaces read, create, and change ratings through the `messageFeedback` service, whose `list`, `put`, and `delete` operations are the whole surface. The one deployment setting is the maximum note length (`maxNoteBytes`), which the Web bundle sets to 8192. Browser controls live in a separate client package; this package provides the service itself.
+This service records positive or negative ratings and optional verbatim notes for finalized assistant messages. The canonical Session log owns every creation, edit, and deletion; `list`, `put`, and `delete` expose current feedback without constructing or waking an Agent. Feedback is log-only and does not enter model history.

 ## Use this package
 
-Choose this service when a product surface should let users rate and annotate individual assistant messages. Feedback attaches only to a finalized message — one that has already been sent — and using the service never starts or resumes an agent. A custom app mounts the service together with session persistence and storage; the shipped Web bundle already composes all of it with `maxNoteBytes: 8192`.
+Mount `dsh-message-feedback` alongside `sessions` and `sessionPersistence`. It needs no storage-domain service. The Web bundle supplies the browser consumer and a note limit of 8192 bytes.
 
 ### Configuration
 
 | Field | Default | Meaning |
 |---|---|---|
-| `maxNoteBytes` | required | Maximum UTF-8 byte length accepted for one optional note. |
+| `maxNoteBytes` | required | Positive safe-integer maximum UTF-8 bytes in one optional note. |
 
-```yaml
-- id: message-feedback
-  name: '@deepseek-ai/dsh-message-feedback'
-  config:
-    maxNoteBytes: 8192
-```
-
-A note must contain at least one non-whitespace character and fit within the configured byte length; a blank note is rejected with `note-blank` and an oversized one with `note-too-large`. Accepted text is stored exactly as submitted — nothing is trimmed. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-message-feedback) is the exhaustive source for every accepted field and its JSDoc.
+A supplied note must contain a non-whitespace character and fit the configured byte limit. Blank notes return `note-blank`; oversized notes return `note-too-large`. Accepted text is preserved exactly, including surrounding whitespace. Omitting a note clears it. Note validation precedes Session lookup.
 
 ### Reading and changing feedback
 
-Callers use three operations to read and change feedback for a session:
-
-| Operation | Request | Success | Rejected when |
+| Operation | Request | Success | Business failures |
 |---|---|---|---|
-| `list` | the session id | the current ratings and notes, in creation order | the session is not found |
-| `put` | session, message, rating, optional note, expected version | the stored rating and note | session not found, message is not a valid target, version conflict, blank or oversized note |
-| `delete` | session, message, expected version | the rating is absent | session not found, version conflict |
+| `list` | Session id | Current items in creation order | Session not found |
+| `put` | Session, message, rating, optional note, expected version | Current item | Session or target not found, version conflict, invalid note |
+| `delete` | Session, message, expected version | Item absent | Session not found, version conflict |
 
-Every change must be based on the version the service returned for that rating: a change based on an older version is rejected with `version-conflict`, and the reply carries the current rating so the caller can see what changed without another read. Deleting a rating that is already absent succeeds, and concurrent changes to different messages do not conflict. An omitted note clears an existing note.
+Create with `ifVersion: null`; edit or delete with the returned version. Stale mutations return `version-conflict` and the current item. Each material put mints a fresh token and preserves the original creation time. A matching no-op put returns the same item without appending an event. Deleting an absent item succeeds regardless of the supplied version, without appending an event. Recreating a deleted item starts a new creation time and ordering position.
 
-### What you can rate
-
-A rating attaches to one finalized assistant message: the message must exist and be an assistant message that was sent. User messages, empty assistant placeholders, and replaced messages are not valid targets and are rejected with `target-not-found`. Once recorded, the rating and note stay with that message and survive restarts; a fork of the session starts with no feedback.
-
-### Durability
-
-A rating is committed only after the message it refers to is durably stored, so feedback never points at a message that can be lost. Reading or writing feedback never starts or resumes an agent; the service inspects the persisted session directly.
-
------
+Targets must be non-empty assistant messages produced by append-origin events. User messages, empty assistant placeholders, and replacement-origin messages return `target-not-found`. Feedback survives restart; a fork starts without owned feedback even when its inherited prefix contains parent feedback.
 
 <a id="understand-the-implementation"></a>
 ## Understand the implementation
 
-<details>
-<summary>Implementation internals — click to expand</summary>
+### Canonical log and durability
 
-### Design concept
+`feedback/message-put` stores the owning Session id and complete item, including its version and timestamps. `feedback/message-delete` stores the owner and message id. Current state is derived from these events, ignoring other Session owners. Durable payloads are validated before use. No second feedback store or cache exists.
 
-The service keeps feedback outside the session log entirely: each session owns one sidecar row in a storage domain, so a rating can never be confused with conversation content, model history, or telemetry. The sidecar is only ever committed after the message it references is durable — the row extends the target log instead of preceding it. Every operation returns a business result that distinguishes a handled failure (missing session, invalid target, stale version, bad note) from an infrastructure failure, which rejects instead of being mislabeled.
+Live operations append through `Session.append` and await `sessions.flush`, then verify the captured log endpoint and Session header through a persistence read handle before reporting success. Cold mutations hold a persistence write handle across read, validation, comparison, append, flush, and close. Cold reads use a read handle. Neither path constructs a Session or appends lifecycle events.
 
-### What a sidecar holds
-
-One row per session binds the inspected session identity (`createdAt`, `cwd`) to its feedback items; the identity fences a reused session id, so a row from an earlier lifecycle is invisible and a fork starts with no feedback. Items are immutable values — a change writes a new version of the item, preserving its creation time — and the row schema rejects duplicate message ids and reused versions so lookup stays unambiguous. The exact row schema and validation live in [`src/spec.ts`](src/spec.ts).
-
-### Concurrency
-
-Mutations are optimistic and per message: a caller sends the version it last observed, a stale version is rejected with the authoritative current item so the caller reconciles without another read, and every material change mints a fresh version token so a stale write can never masquerade as current. A per-session queue serializes the whole read-compare-write through one service instance; storage provides no cross-process conditional write, which is the Known Limitation below.
-
-### Durability and target validation
-
-A write is staged, verified, then committed: the target message is flushed through the canonical checkpoint, the physical log prefix is re-read, and only then is the sidecar row written — feedback can never reference a message that is not durable. Cold sessions are read without resuming an agent, absence is decided by the persistence store's `stat` rather than guessed, and only a real, sent assistant message is a valid target. The flush and read path lives in [`src/index.ts`](src/index.ts).
-
-### Failure modes
-
-The service fails closed: disposal drains in-flight writes before closing the domain, a write submitted after disposal starts is rejected as a lifecycle failure, and invalid configuration or a read before domain initialization fails loudly.
+A per-Session queue serializes operations within one service instance; the persistence write handle excludes competing cold writers. Disposal stops admission and drains admitted operations before releasing the service. Persistence failures reject instead of becoming business failures. A failed flush does not roll back an accepted event; callers can list and retry with its version. Successful no-op mutations also flush the current prefix.

 ## Model Experience
 
-### Local message-feedback state
+### Message feedback
 
 #### What the model sees
 
-Nothing. `ctx.messageFeedback` registers no tool, prompt section, model-facing context, or Session event; feedback stays in a Host-owned sidecar unless a separately documented Consumer explicitly exposes it.
+Nothing. `feedback/message-put` and `feedback/message-delete` carry no surface placement, tool, prompt section, or model-facing context. Log export and delivery policies belong to their consumers.
 
 #### Token effect
 
-Zero. No request, result, rating, note, timestamp, or failure from this package enters a model request.
+Zero. Ratings, notes, and service results do not enter model requests.
 
 #### KV Cache effect
 
-Independent. Listing or mutating message feedback does not touch a model request prefix and cannot invalidate an otherwise reusable provider cache entry.
+Independent. Feedback does not change the model request prefix.
 
 ## Known Limitations and Deferred Work
 
 <a id="known-limitations-and-deferred-work"></a>
 
-
-These limits define when the service is a poor fit or needs special operational care. They are current package constraints, not a task backlog.
-
-- **Compare-and-set is single-process** — the per-Session queue serializes one service instance only; storage-domain has no cross-process conditional write, so multiple Host processes writing one storage root can still lose updates.
-- **No durable Session deletion cascade** — Session persistence has no deletion API, and `session/disposed`/`api-session/removed` mean detach rather than durable deletion. The service therefore retains empty rows and may leave orphan rows after out-of-band log removal instead of deleting valid feedback on detach.
-- **Header identity is not a content fingerprint** — `{createdAt, cwd}` detects reuse only when those fields differ; a cloned log retaining the same header identity is indistinguishable.
-- **Trusted caller boundary** — `list`/`put`/`delete` carry no authenticated actor or audit identity. A deployment must expose the Host gateway only through its trusted or separately authenticated boundary until authorization and attribution are added.
-- **Row bounds** — `maxNoteBytes` bounds one note, but the item count and aggregate retained bytes of one Session row are not capped; a deployment-owned row bound remains deferred until a concrete consumer defines its policy.
+- **Log-only authority:** existing `message_feedback` sidecar data is neither read nor migrated. Those files remain untouched, but their feedback is unavailable through this service.
+- **Deletion retains history:** delete removes current feedback, not earlier ratings or notes from the append-only log; it is not a privacy-erasure operation.
+- **Writer ownership:** another process holding a Session write handle causes cold mutations to reject. The service does not wake that owner or coordinate Remote calls across processes.
+- **Trusted callers:** requests contain no authenticated actor or audit identity. Deployments must protect the Host gateway.
+- **Telemetry export:** the shipped OTel row is disabled. If enabled in `FULL`, it exports live feedback events; in `FEEDBACK_ONLY`, `/feedback` releases the pending canonical-log prefix, including message-feedback ratings and verbatim notes, not just the command text. Deployments own redaction; see the [OTel export policy](../../session/session-telemetry-otel/README.md).
+- **Scan cost:** each `list`, `put`, or `delete` that reaches an existing Session scans its full event log to derive current feedback; cold operations also read the full log from persistence. Work grows with total Session history, not just the number of feedback items.
+- **Retention:** `maxNoteBytes` limits one note, not aggregate log size or mutation count.

 ### Dev Note

-<summary>Working context for maintainers — click to expand</summary>
-
-This Dev Note is working context for maintainers; it is explicitly non-authoritative. Shipped behavior, limits, and rationale live in the sections above, the package code, and the linked Agent Note.
-
-- The browser controls and the client Remote mount live in `dsh-client-ui-message-feedback` and `dsh-api-remotes`; their open items belong to those packages' notes.
-- The trusted-caller limitation is the open authorization direction: the Host gateway records no actor or audit identity, and any authentication layer must land at the deployment boundary before the service exposes per-user attribution.
-- Note validation precedes Session lookup by design, so `note-blank` and `note-too-large` win over `session-not-found` for a missing Session; tests pin this order.

 ## 概述
 
-`dsh-message-feedback` 让产品界面提供逐消息反馈：用户可以把一条 assistant 消息标记为好评或差评，并可附上简短备注，评分会与该消息绑定。评分与会话一起保存，重启后依然存在，并且绝不会进入模型历史或遥测。产品界面通过 `messageFeedback` 服务读取、创建和修改评分，其 `list`、`put`、`delete` 三个操作就是全部对外表面。唯一需要部署方设置的项是备注最大长度（`maxNoteBytes`），Web 组合将其设为 8192。浏览器控件位于独立的客户端包中；本包提供服务本身。
+本服务为已完成的 assistant 消息记录好评、差评及可选的原样备注。每次创建、编辑和删除都由权威 Session 日志保存；`list`、`put` 和 `delete` 提供当前反馈，不会构造或唤醒 Agent。反馈仅写入日志，不进入模型历史。

 <a id="use-this-package"></a>
 ## 使用本包
 
-当产品界面需要让用户对单条 assistant 消息评分或加备注时，选择此服务。反馈只绑定已完成的（即已发出的）消息，并且使用该服务绝不会启动或恢复 agent。自定义应用需要把此服务与会话持久化和存储一起挂载；随附的 Web 组合已用 `maxNoteBytes: 8192` 组合好全部组件。
+将 `dsh-message-feedback` 与 `sessions`、`sessionPersistence` 一起挂载。它不需要 storage-domain 服务。Web 组合提供浏览器消费方，并将备注上限设为 8192 字节。
 
 ### 配置
 
 | 字段 | 默认值 | 含义 |
 |---|---|---|
-| `maxNoteBytes` | 必填 | 一条可选备注的最大 UTF-8 字节长度。 |
+| `maxNoteBytes` | 必填 | 单条可选备注的 UTF-8 字节上限，必须为正安全整数。 |
 
-```yaml
-- id: message-feedback
-  name: '@deepseek-ai/dsh-message-feedback'
-  config:
-    maxNoteBytes: 8192
-```
-
-备注必须包含至少一个非空白字符，并且不得超过配置的字节长度；空白备注会以 `note-blank` 拒绝，超长备注会以 `note-too-large` 拒绝。通过校验的文本按提交原样存储——不做任何 trim。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-message-feedback)是每个受支持字段及其 JSDoc 的穷尽式真源。
+提交的备注必须包含非空白字符，且不超过配置的字节上限。空白备注返回 `note-blank`；过长备注返回 `note-too-large`。通过校验的文本会完整保留，包括首尾空白。省略备注会清除它。备注校验先于 Session 查找。
 
 ### 读取与修改反馈
 
-调用方用三个操作读取和修改某个会话的反馈：
-
-| 操作 | 请求 | 成功 | 拒绝时机 |
+| 操作 | 请求 | 成功 | 业务失败 |
 |---|---|---|---|
-| `list` | 会话 id | 当前的评分与备注，按创建顺序 | 会话不存在 |
-| `put` | 会话、消息、评分、可选备注、期望的 version | 已存储的评分与备注 | 会话不存在、消息不是有效目标、version 冲突、备注空白或超长 |
-| `delete` | 会话、消息、期望的 version | 评分已不存在 | 会话不存在、version 冲突 |
+| `list` | Session id | 按创建顺序返回当前条目 | Session 不存在 |
+| `put` | Session、消息、评分、可选备注、预期版本 | 当前条目 | Session 或目标不存在、版本冲突、备注无效 |
+| `delete` | Session、消息、预期版本 | 条目不存在 | Session 不存在、版本冲突 |
 
-每次修改都必须基于服务为该项评分返回的 version：基于更旧 version 的修改会以 `version-conflict` 拒绝，且回复携带当前评分，调用方无需再次读取即可看到变化。删除一条已经不存在的评分会成功；对不同消息的并发修改互不冲突。省略 `note` 会清除已有备注。
+创建时传入 `ifVersion: null`；编辑或删除时使用返回的版本。陈旧修改返回 `version-conflict` 及当前条目。每次实质 put 都生成新 token，并保留原始创建时间。匹配的无变化 put 返回相同条目，不追加事件。删除不存在的条目始终成功，不受所传版本影响，也不追加事件。重新创建已删除条目会产生新的创建时间和排序位置。
 
-### 可以对什么评分
-
-评分绑定一条已完成的 assistant 消息：消息必须存在，并且是发送过的 assistant 消息。用户消息、空的 assistant 占位与已被替换的消息都不是有效目标，会以 `target-not-found` 拒绝。评分与备注一旦记录就与该消息绑定并跨重启保留；会话的 fork 从没有反馈开始。
-
-### 持久性
-
-只有当评分所指的消息已被持久存储后，评分才会提交，因此反馈绝不会指向可能丢失的消息。读取或写入反馈绝不会启动或恢复 agent；服务直接检查已持久化的会话。
-
------
+目标必须是由 append 来源事件产生的非空 assistant 消息。用户消息、空 assistant 占位及 replacement 来源消息返回 `target-not-found`。反馈跨重启保留；fork 即使继承了包含父会话反馈的前缀，也从没有自有反馈开始。
 
 <a id="understand-the-implementation"></a>
 ## 理解实现
 
-<details>
-<summary>实现细节——点击展开</summary>
+### 权威日志与持久性
 
-### 设计理念
+`feedback/message-put` 保存所属 Session id 及完整条目，包括版本和时间戳。`feedback/message-delete` 保存所属 Session 和消息 id。当前状态从这些事件推导，忽略属于其他 Session 的事件。持久化 payload 在使用前经过校验。不存在第二个反馈存储或缓存。
 
-服务把反馈完全放在会话日志之外：每个会话在存储域中拥有一条伴随记录行，因此评分绝不会与对话内容、模型历史或遥测混淆。伴随记录只在所引用消息已持久之后提交——该行是目标日志的延伸，而不是先于它。每个操作都返回业务结果，把已处理的失败（会话缺失、目标无效、版本陈旧、备注不合格）与基础设施故障区分开，后者会 reject 而非被误标。
+活跃会话通过 `Session.append` 追加，并等待 `sessions.flush`，然后通过持久化读 handle 核实捕获的日志末端与 Session header，才会报告成功。冷会话修改在读取、校验、比较、追加、flush 和关闭期间持有持久化写 handle。冷读取使用读 handle。两条路径都不会构造 Session 或追加生命周期事件。
 
-### 伴随记录里有什么
-
-每个会话一行，把检查所得的会话身份（`createdAt`、`cwd`）与其反馈条目绑定；该身份隔离复用的会话 id，因此更早生命周期的行不可见，fork 也从无反馈开始。条目是不可变值——修改会写入条目新版本并保留其创建时间——行 schema 拒绝重复消息 id 与复用的版本，保证查找无歧义。精确的行 schema 与校验见 [`src/spec.ts`](src/spec.ts)。
-
-### 并发
-
-修改是乐观的、按消息进行的：调用方发送其最后观察到的 version，陈旧的 version 会连同权威当前条目一起被拒绝，调用方无需再次读取即可协调；每次实质修改都会铸造新的 version token，陈旧写入绝不会被误认为当前。按 Session 的队列把整个读-比较-写串行化在一个服务实例内；存储不提供跨进程条件写，这正是下文「已知限制」。
-
-### 持久性与目标校验
-
-写入按「暂存—校验—提交」进行：目标消息先通过权威 checkpoint flush，再物理重读日志前缀，之后才写入伴随记录行——反馈绝不会引用尚未持久的消息。冷会话在不恢复 agent 的情况下被读取，缺失由持久化存储的 `stat` 判定而非猜测，只有真实发送过的 assistant 消息才是有效目标。flush 与读取路径见 [`src/index.ts`](src/index.ts)。
-
-### 故障模式
-
-服务失败时保持封闭：disposal 先排空在途写入再关闭域，disposal 开始后提交的写入会以生命周期故障拒绝，无效配置或域初始化前的读取都会明确失败。
+每个 Session 的队列在同一服务实例内串行化操作；持久化写 handle 排除其他冷写入方。销毁时停止接收操作并排空已接收操作，然后释放服务。持久化故障会 reject，而非变成业务失败。flush 失败不会回滚已接受的事件；调用方可以读取并使用其版本重试。成功的无变化修改也会 flush 当前前缀。

 ## 已知限制与延期工作
 
 <a id="known-limitations-and-deferred-work"></a>
 
-
-这些限制说明服务何时不合适，或何时需要特别的运维注意。它们是当前包约束，不是任务积压。
-
-- **Compare-and-set 仅限单进程**——按 Session 划分的队列只串行化一个服务实例；storage-domain 不提供跨进程条件写，因此多个 Host 进程写入同一存储根目录时仍可能丢失更新。
-- **没有持久 Session 删除级联**——Session persistence 没有删除接口，且 `session/disposed`/`api-session/removed` 表示 detach 而非持久删除。因此服务会保留空行，并可能在带外移除日志后留下遗留行，而不会在 detach 时删除仍有效的反馈。
-- **Header 身份不是内容指纹**——只有 `{createdAt, cwd}` 不同时才能识别复用；本契约无法区分保留相同 header 身份的克隆日志。
-- **调用方边界受信任**——`list`/`put`/`delete` 不携带已认证的 actor 或审计身份。在加入授权与归属信息前，部署方必须只通过受信任或另行认证的边界暴露 Host gateway。
-- **行边界**——`maxNoteBytes` 只限制单条备注，单个 Session 行的条目数和聚合保留字节尚无上限；由部署决定的行边界，延后到具体消费方明确策略时处理。
+- **仅日志具有权威性：**不读取或迁移现有 `message_feedback` 伴随数据。这些文件保持不变，但其反馈无法通过本服务访问。
+- **删除保留历史：**delete 移除当前反馈，不会从只追加日志中清除更早的评分或备注；它不是隐私擦除操作。
+- **写入所有权：**另一个进程持有 Session 写 handle 时，冷会话修改会 reject。服务不会唤醒该所有者，也不协调跨进程 Remote 调用。
+- **受信任调用方：**请求不包含经过认证的 actor 或审计身份。部署方必须保护 Host gateway。
+- **遥测导出：**随附的 OTel 配置行处于禁用状态。启用后，`FULL` 会实时导出反馈事件；`FEEDBACK_ONLY` 则在 `/feedback` 时释放尚未导出的权威日志前缀，包括 message-feedback 评分和原样备注，而不只是命令文本。部署方负责脱敏；见 [OTel 导出策略](../../session/session-telemetry-otel/README.zh.md)。
+- **扫描成本：**每次访问已有 Session 的 `list`、`put` 或 `delete` 都会扫描完整事件日志来推导当前反馈；冷会话操作还会从持久化存储读取完整日志。工作量随 Session 历史总量增长，而不只是反馈条目数。
+- **保留量：**`maxNoteBytes` 只限制单条备注，不限制日志总大小或修改次数。

 Live message-feedback mutations append through the owning Session and await its durability checkpoint; cold mutations hold a persistence write handle across read, comparison, append, and flush without creating a Session or Agent. A matching no-op appends nothing but still awaits persistence. Failures propagate, and a failed live flush can leave an observable in-memory item for retry. Per-item versions prevent unrelated message edits from conflicting; strict stale-write rejection prevents ABA overwrites even when the desired value matches.

+# Agent Note: Explicit-feedback-only upload through OpenTelemetry
+
+Status: implemented
+
+English | [中文](2026-09-05-nonofficial-feedback-otel.zh.md)
+
+## Problem
+
+Feedback needs the session context it describes and a delivery path independent of the model provider or a later model request. Ordinary activity must not authorize uploads. Inherited feedback must not count as a child Session's consent.
+
+## Decision
+
+The base mounts OTel in `FEEDBACK_ONLY` for all users and providers, including `deepseek-official` and Sessions without a request header. Only new own `feedback/record`, `feedback/message-put`, and `feedback/message-delete` events authorize capture through that exact canonical event. Text feedback, ratings, material note edits, and withdrawals count. Cold `feedback/committed` notifications supply a committed snapshot without publishing a live Session or Agent.
+
+An authorized prefix includes all unhanded canonical context from seq 0 through the feedback, not just its payload. A child needs its own new feedback; its prefix then includes inherited history. Later records wait for the next explicit feedback. Request activity, request headers, Session creation or adoption, restoration, plugin mount, and HMR never authorize capture; stored feedback alone triggers nothing.
+
+The backend uses on-demand capture with complete history and the existing redaction waterfall. `DISABLED` constructs no transport. `FULL` is rejected rather than aliased. Direct `ctx.sessionTelemetry.emit()` calls are no-ops, so callers cannot bypass feedback authorization. SDK scheduled flush and shutdown may finish previously authorized batches but never capture new records. Sending after submission needs no further user interaction or model call.
+
+The [canonical-feedback decision](2026-09-05-canonical-feedback-log.md) owns storage, versions, deletion, and plain command confirmation. The [opt-in DeepSeek contribution](../../../../packages/session/session-log-deepseek/README.md) remains independent, with its existing destination and acceptance behavior.
+
+## Alternatives considered
+
+**Filter by provider or endpoint hostname.** Feedback authorizes the same bounded context for every user; a provider choice, gateway, or missing header does not change that authorization.
+
+**Use only later DeepSeek requests.** Other providers do not carry `dsh_session_log`, and final feedback may have no subsequent request. The existing OTel pipeline sends independently without a custom uploader or model call.
+
+**Keep continuous capture or replay stored feedback on lifecycle events.** Deployment configuration and old feedback do not authorize new capture. Only a new explicit submission does. Parent feedback likewise cannot authorize a child upload.
+
+## Consequences
+
+Handoff is best-effort, not collector acceptance. Same-object cursors suppress repeated capture, but fresh cold snapshots and new feedback after restart can repeat prefixes; receivers deduplicate on `(session.id, session.format_version, event.seq)`. There is no durable OTel outbox, delivery watermark, or harness HTTP retry promise. SDK batching and loss behavior apply after enqueue. OTel and the opt-in DeepSeek path can overlap. Withdrawal exports a deletion event, not remote erasure.

+[OTel tests](../../../../packages/session/session-telemetry-otel/tests/otel.spec.ts) cover explicit-feedback capture, provider-independent behavior, lifecycle silence, fork consent, cold commits, and direct-call denial.

+
+## 问题
+
+反馈需要它所描述的会话上下文，以及不依赖模型提供方或后续模型请求的投递路径。普通活动不得授权上传。继承的反馈不得视为子 Session 的同意。
+
+## 决策
+
+基础配置为所有用户和提供方以 `FEEDBACK_ONLY` 挂载 OTel，包括 `deepseek-official` 和没有请求头的 Session。只有新的自身 `feedback/record`、`feedback/message-put` 和 `feedback/message-delete` 事件授权捕获，且截止该确切的权威事件。文本反馈、评分、实质备注编辑与撤回均算作反馈。冷会话 `feedback/committed` 通知提供已提交快照，不发布存活 Session 或 Agent。
+
+授权前缀包含从 seq 0 到该反馈的所有尚未交接的权威上下文，而非只有反馈载荷。子会话需要新的自身反馈；之后其前缀包含继承历史。后续记录等待下一次显式反馈。请求活动、请求头、Session 创建或接纳、恢复、插件挂载和 HMR（热模块替换）绝不授权捕获；仅有存储的反馈不会触发任何上传。
+
+后端使用包含完整历史的按需捕获与现有脱敏 waterfall（瀑布式事件）。`DISABLED` 不构造传输。`FULL` 被拒绝，不作为别名。直接调用 `ctx.sessionTelemetry.emit()` 是空操作，因此调用方不能绕过反馈授权。SDK 定时刷新和关闭可以完成先前已授权的批次，但绝不捕获新记录。提交后的发送无需进一步用户交互或模型调用。
+
+[权威反馈决策](2026-09-05-canonical-feedback-log.zh.md)负责存储、版本、删除与纯命令确认。[需主动开启的 DeepSeek 贡献](../../../../packages/session/session-log-deepseek/README.zh.md)保持独立，保留现有目标与接受行为。
+
+## 考虑过的替代方案
+
+**按提供方或端点主机名过滤。** 反馈为每位用户授权相同的有界上下文；提供方选择、网关或缺失请求头不改变该授权。
+
+**仅使用后续 DeepSeek 请求。** 其他提供方不携带 `dsh_session_log`，而最终反馈之后可能没有请求。现有 OTel 流水线可独立发送，无需自定义上传器或模型调用。
+
+**保留持续捕获或在生命周期事件上回放存储的反馈。** 部署配置和旧反馈不授权新捕获。只有新的显式提交才授权。父会话反馈同样不能授权子会话上传。
+
+## 后果
+
+交接尽力而为，不代表采集端接受。同对象游标抑制重复捕获，但新冷快照和重启后的新反馈可能重复前缀；接收方按 `(session.id, session.format_version, event.seq)` 去重。没有持久化 OTel outbox、投递水位或 harness HTTP 重试承诺。入队后适用 SDK 批处理与丢失行为。OTel 与需主动开启的 DeepSeek 路径可能重叠。撤回导出删除事件，不是远端擦除。

Buffer-free on-demand capture uses the same one-record-per-event mapping through an optional inclusive boundary.

 - **The `session-telemetry/record` waterfall** — the delta over the branch version and the seam's redaction extension point.

 **Map onto OTel spans (GenAI semantic conventions) instead of logs.** Rejected for this revival: the branch implementation's log mapping is reviewed and shipped-shaped; the span model is lossy for forkable, interruptible sessions and belongs to a future consumer with real span queries to serve.
 
-**Replay the complete constructor seed for every new Session object.** Rejected because a fork's inherited events and a resumed or migrated log belong to another lifecycle and may predate the current sharing act. Replaying them under the new object can re-release already shared data, attribute inherited events to a child Session, and make feedback acknowledgement text understate what is handed off. A new object therefore starts immediately before `firstLiveSeq`: fresh Sessions still begin at seq 0, while seeded Sessions begin with their lifecycle boundary. Re-adopting the same object resumes after its cursor, so HMR does not duplicate the settled lifecycle suffix. This rule does not provide crash backfill; a deployment requiring guaranteed historical delivery needs the deferred durable outbox and an explicit disclosure for that broader scope.
+**Replay every constructor seed automatically.** A fork's inherited events and a resumed log may predate the current sharing act. The coordinator defaults to `firstLiveSeq` for a new object; `includeHistory` explicitly permits a backend to capture stored context. OTel selects complete history only through new own feedback, never on construction, restoration, or HMR. Same-object cursors reduce duplicate handoff but do not guarantee historical delivery or replace the deferred durable outbox.
 
 **Forwarding the seam's turn-boundary `flush()` hint to the OTel provider's `forceFlush()`.** Shipped in the first revival round, then removed: three distinct silent-loss paths shared the wrapper state — a dispose racing an in-flight flush (the SDK's concurrent-flush guard makes shutdown's internal drain skip), overlapping hints displacing the retained promise, and the provider's fixed 30-second flush timeout rejecting while the processor still drains. Every path exists only because the forwarding made this backend the process's second flusher against undocumented SDK internals from the upstream experimental tree; with no `flush()` implemented, the batch processor is the only flusher, its `scheduledDelayMillis` (already deployment-tunable through the `processor` passthrough) governs export cadence, and `shutdown()`'s drain is complete by construction. Reinstate only if a deployment states a turn-boundary latency requirement `scheduledDelayMillis` cannot meet — and then by calling the retained `BatchLogRecordProcessor`'s own `forceFlush()`, never the provider's timeout-wrapped one.
 
 ## Consequences
 
-A deployment adds one `cordis.yml` entry with an OTLP endpoint and explicitly selects `FULL` to stream lifecycle-local canonical events into an OTel-compatible stack or `FEEDBACK_ONLY` to replay a lifecycle-local canonical-log prefix when feedback is recorded. `DISABLED` is the default ([`dsh-session-telemetry-otel` README](../../../../packages/session/session-telemetry-otel/README.md)) and constructs no reporting pipeline; removing the entry remains a silent opt-out, while the disabled mode keeps the local feedback warning. A rule-free deployment exports each event body exactly as captured — including every assistant chunk and any credentials embedded in file contents or command output — so a deployment crossing a trust boundary must mount `session-telemetry/record` listeners, and both READMEs state this plainly. Where rules are mounted, exported bodies can differ from canonical log bytes, so receivers must not treat telemetry as a byte-exact replica; the log remains the source of truth. Same-object replay after lost cursor state can duplicate lifecycle-local ledger rows, and crash durability remains out of scope until the outbox decision above is revisited.

 ## Decision
 
-The [canonical feedback decision](../architecture/2026-09-05-canonical-feedback-log.md) supersedes this default composition: the shipped base disables its OTel row. The optional backend retains its modes; the release-boundary rationale below does not authorize upload in a default installation.
+The [explicit-feedback OTel decision](../architecture/2026-09-05-nonofficial-feedback-otel.md) owns upload authorization for all users, including `deepseek-official`. This note retains the rationale for the base default: feedback-gated release rather than continuous export.
 
-When explicitly enabled without replacing its config, the shared base's OTel row resolves an unset or empty `DSH_TELEMETRY_MODE` to `FEEDBACK_ONLY`. The plugin's own omitted-`mode` default remains `DISABLED`; `FULL` and `DISABLED` are explicit environment overrides, and non-empty `DSH_TELEMETRY_DISABLED` remains the pre-load hard opt-out. In `FEEDBACK_ONLY`, each `feedback/record` releases the canonical suffix after the same Session object's handoff cursor through that event. A new object starts at its constructor boundary: a fresh Session begins at seq 0, while a forked, resumed, or migrated Session excludes its constructor seed and begins with this lifecycle's `session/end-seed`.
+The shared base resolves an unset or empty `DSH_TELEMETRY_MODE` to `FEEDBACK_ONLY`. The plugin's own omitted-`mode` default is `DISABLED`; `FULL` rejects, and non-empty `DSH_TELEMETRY_DISABLED` is the pre-load hard opt-out. New own text feedback, message-rating edits, and withdrawals release the unhanded canonical prefix through that event, including stored context. Inherited parent feedback does not authorize a child export.
 
-Feedback-gated release lets a reporter share the lifecycle that exhibited the problem without reproducing it. It trades continuous export for an explicit feedback trigger, but a deployment must establish consent before enabling that policy. The [archived default-off](../../archived/feature/2026-08-10-telemetry-default-off.md) and [default-mount](../../archived/feature/2026-07-31-web-telemetry-default-mount.md) notes record the earlier composition; the [base patch](../../../../packages/bundle/base/cordis.patch.yml) and [OTel README](../../../../packages/session/session-telemetry-otel/README.md) own current configuration.
+Feedback-gated release lets a reporter share the Session that exhibited the problem without reproducing it. It trades continuous export for an explicit feedback trigger. The [archived default-off](../../archived/feature/2026-08-10-telemetry-default-off.md) and [default-mount](../../archived/feature/2026-07-31-web-telemetry-default-mount.md) notes record the earlier composition; the [base patch](../../../../packages/bundle/base/cordis.patch.yml) and [OTel README](../../../../packages/session/session-telemetry-otel/README.md) own current configuration.
 
 ## Alternatives considered
 
 **Require reporters to re-run after enabling telemetry.** Rejected as the feedback-gated workflow: the Session that exhibited the problem is the useful evidence, and re-running loses it.
 
-**Default to `FULL`.** Rejected: a fresh installation does not authorize continuous export without user action.
+**Permit continuous export.** Rejected: deployment configuration does not authorize capture without explicit feedback.
 
-**Use only subsequent DeepSeek requests for delivery.** The canonical feedback decision accepts this for the shipped default, including the risk that a final feedback entry remains local. The optional feedback-gated OTel mode retains its event-time release trigger; request-time delivery cannot provide that timing without initiating another request.
+**Use only subsequent DeepSeek requests for delivery.** The independent opt-in contribution can carry canonical feedback, but a final feedback entry may have no later request. OTel releases it for every provider without initiating another LLM request.
 
 ## Consequences
 
-- The shipped base uploads nothing through OTel. An explicitly enabled `FEEDBACK_ONLY` backend hands off the unreleased lifecycle-local prefix only on `feedback/record`; message-rating events do not themselves trigger release.
+- The shipped base releases a bounded prefix only at new explicit feedback. Ordinary requests, lifecycle events, and stored feedback do not trigger capture. Later records wait for the next explicit feedback.
 - On-demand capture copies and redacts the canonical log at feedback time. Without a deployment redaction rule, exported data can include message text, tool arguments and results, and workspace paths.
 - The command acknowledgement confirms recording, not sharing or delivery. A deployment requiring prior informed consent must provide it before enabling uploads; OTel handoff remains subject to the SDK's batching, retry, and loss policy.

 ## 考虑过的替代方案
 
 **要求报告者启用遥测后重跑。** 不作为反馈门控工作流：值得保留的证据是出问题的那个 Session，重跑会丢掉它。
 
-**默认 `FULL`。** 否决：全新安装不授权没有用户动作的持续导出。
+**允许持续导出。** 否决：部署配置不授权没有显式反馈的捕获。
 
-**仅通过后续 DeepSeek 请求投递。** 权威反馈决策为随附默认配置接受此方案，包括最后一条反馈可能留在本地的风险。可选反馈门控 OTel 模式保留事件发生时的释放触发；请求时投递若不发起另一个请求，就无法提供这种时机。
+**仅通过后续 DeepSeek 请求投递。** 独立的需显式启用的贡献可传送权威反馈，但最终反馈之后可能没有请求。OTel 为每个提供方释放反馈，无需发起另一个 LLM 请求。
 
 ## 后果
 
-- 随附基础配置不通过 OTel 上传任何内容。显式启用的 `FEEDBACK_ONLY` 后端只在 `feedback/record` 时交接未释放的生命周期本地前缀；消息评分事件本身不触发释放。
+- 随附基础配置仅在新的显式反馈时释放有界前缀。普通请求、生命周期事件和已存储反馈不触发捕获。后续记录等待下一次显式反馈。
 - 按需捕获在反馈时复制权威日志并脱敏。部署未挂载脱敏规则时，导出数据可能包含消息文本、工具参数和结果，以及 workspace 路径。
 - 命令确认文本确认记录，而非共享或投递。要求事先知情同意的部署必须在启用上传前提供该步骤；OTel 交接仍受 SDK 的批处理、重试与丢失策略约束。

-The base bundle mounts the native DeepSeek adapter, settings and credential providers, stable `web_search` and `web_fetch`, the public-only HTTP fetch provider, and opt-in DeepSeek session-log upload. Provider credentials resolve from the inherited environment, `$DSH_HOME/.credentials.yaml`, the invoking directory's `.env`, then `$DSH_HOME/.env`; the managed document is never materialized into `process.env`, while both `.env` files are ordinary launch environment layers. Search uses `DEEPSEEK_API_KEY` and accepts `DEEPSEEK_SEARCH_BASE_URL`. Enabled fetch calls run in every sandbox and approval mode without per-call confirmation; the provider rejects non-public destinations before connecting. The Web app disables the base tool row and exposes the same tools through its `cordis`, `ptc`, and `standard` agent presets.

Process-local `agent/assistant-stream` frames do not enter this durable feed.

 ## The sharing disclosure
 
-The seam's acknowledgement contract (owned by the [Service Definition README's sharing-disclosure section](../../packages/session/session-telemetry/README.md#the-sharing-disclosure)): every backend discloses its deployment-selected sharing policy through the required abstract `sharing` member on `ctx.sessionTelemetry`, and consumers render "not configured" only when no telemetry service is mounted. The disclosure states the current policy, never delivery or retention — handoff is the non-blocking enqueue, and batching, retry, and loss policy stay the reporting SDK's.
+Every backend exposes its deployment-selected mode through the required abstract `sharing` member on `ctx.sessionTelemetry` ([Service Definition README](../../packages/session/session-telemetry/README.md#the-sharing-disclosure)). This is neither a per-Session admission decision nor a delivery receipt. The `/feedback` acknowledgement does not consult it.
 
 ```ts type-equiv

- * {@link SessionTelemetryBackend} backend to human-facing acknowledgement surfaces (the
- * `/feedback` command's confirmation text). The Service Definition owns the
- * vocabulary so consumers and backends do not depend on a specific provider.
+ * Deployment-selected session-sharing mode, not confirmation of SDK delivery.
  */
 type SessionTelemetrySharingStatus = 'full' | 'feedback-only' | 'disabled'
 ```
 
+## Capture policy
+
+```ts type-equiv
+/** Whether capture follows live events or reads the canonical log only when requested. */
+type SessionTelemetryCapture = 'live' | 'on-demand'
+```
+
+```ts type-equiv
+/** Backend-selected capture mode and history policy. */

+  /** Follow live events, or wait for explicit capture; defaults to live. */
+  capture?: SessionTelemetryCapture
+  /** Include stored history before this lifecycle; defaults to false. */
+  includeHistory?: boolean
+}
+```
+
+`includeHistory` permits stored and inherited records but does not itself authorize capture. The [OTel backend](../../packages/session/session-telemetry-otel/README.md) uses on-demand capture and requires new own explicit feedback; it releases only the complete prefix through that feedback, for every provider.

 ## Summary
 
-`dsh-session-telemetry-otel` delivers session records through OpenTelemetry logs and is the only entry a deployment loads for the [session-telemetry seam](../session-telemetry/README.md). Its `mode` decides whether session records follow the live stream, are released only at recorded feedback, or stay local: `FULL` hands every record to the OTel SDK immediately, `FEEDBACK_ONLY` replays the canonical log when a `feedback/record` lands, and `DISABLED` (the default) constructs nothing and shares nothing. Uploading modes compose the OTel JS SDK as-is — `LoggerProvider` → `BatchLogRecordProcessor` → OTLP/HTTP log exporter — and map each record onto `logger.emit()`, so batching, retry, queueing, and loss policy follow the SDK. Records carry the complete event data as the seam's redaction waterfall returns it, so a deployment exporting beyond a trusted boundary mounts its own redaction rules. Modes, configuration, and the export surface come first; the implementation internals live in a collapsible developer section below.
+`dsh-session-telemetry-otel` exports session records through the OTel JS SDK only after new explicit feedback, for all users and providers, including `deepseek-official`. `FEEDBACK_ONLY` releases the canonical prefix through that feedback, including context; later records wait for the next explicit feedback. `DISABLED` constructs no transport. SDK batching can finish an authorized upload without another user interaction or model call. Deployments own their redaction rules.

+Direct `ctx.sessionTelemetry.emit()` calls are no-ops in every mode and cannot bypass feedback authorization. Inherited parent feedback does not authorize a child export: the child needs new feedback of its own. Its authorized prefix then includes inherited context.

+Model requests, request headers, Session creation or adoption, restoration, and plugin mount or HMR do not authorize capture. Stored feedback alone triggers nothing. SDK scheduled flush and shutdown may finish batches authorized earlier, but never capture new records.

 ### Design concept
 
-The backend is a thin adapter over the OTel JS SDK: it owns capture mode, resource identity, and an outer shutdown deadline, and passes everything else through verbatim. Two instrumentation scopes separate record channels — ledger records on `@deepseek-ai/dsh-session-telemetry-otel`, operational records on `@deepseek-ai/dsh-session-telemetry-otel/ops` — so receivers can alert on ops without summing them. Resource identity carries `service.name`/`service.version` from `dsh-llm`'s `APP_IDENTITY` plus the package's anonymous `user.id` (from `$DSH_HOME/.anonymous-user-id`), once per export batch rather than per record.

 ### Capture wiring
 
-`FULL` composes the coordinator in `live` mode and lets direct service calls through; `FEEDBACK_ONLY` composes it in `on-demand` mode, gives the coordinator a private backend capability, and triggers `captureSession(session, event.seq)` only when `session.eventAt(event.seq) === event` confirms the exact canonical feedback record; `DISABLED` registers nothing but a warning on `feedback/record`. The backend deliberately implements no `flush()`: the batch processor owns ordinary flushing, and forwarding the hint to `forceFlush()` would create the sole source of concurrent flushes whose interaction with shutdown's drain is undocumented.
+The backend uses on-demand capture with stored history included. Only new own `feedback/record`, `feedback/message-put`, or `feedback/message-delete` events trigger live capture, bounded by that event. A cold `feedback/committed` notification supplies its committed canonical snapshot without publishing a live Session or Agent. Same-object handoff cursors suppress repeated capture. The backend implements no `flush()`; the SDK owns batching and shutdown drain.
 
 ### Field mapping
 
-Each seam record maps onto one SDK log record: `time` and `severity` become the SDK timestamp and severity fields, and `body` and `attributes` carry through verbatim; the exact field mapping lives in [`src/index.ts`](src/index.ts). In `FULL`, receivers can detect crashes by `shutdown`-record absence — the marker is emitted at the session's own disposal or application teardown, and a marker followed by more events is a telemetry reload. In `FEEDBACK_ONLY`, a released prefix normally has no later `shutdown` marker, so its absence is not a crash signal.
+Each telemetry record maps to one SDK log record with captured timestamp, severity, body, and attributes. Feedback authorizes the complete unhanded prefix, not only the feedback payload.

 ## 概述
 
-`dsh-session-telemetry-otel` 通过 OpenTelemetry 日志投递会话记录，是[会话遥测 seam](../session-telemetry/README.zh.md) 的后端，也是部署方唯一要加载的条目。其 `mode` 决定会话记录是跟随实时流、仅在记录反馈时释放，还是留在本地：`FULL` 把每条记录立即交给 OTel SDK，`FEEDBACK_ONLY` 在 `feedback/record` 落地时回放权威日志，`DISABLED`（默认值）不构造任何内容也不共享任何内容。上传模式会原样组合 OTel JS SDK——`LoggerProvider` → `BatchLogRecordProcessor` → OTLP/HTTP 日志导出器——并把每条记录映射到 `logger.emit()`，因此批处理、重试、排队与丢失策略都遵循 SDK。记录携带 seam 脱敏 waterfall（瀑布式事件）返回的完整事件数据，因此向可信边界之外导出的部署方要挂载自己的脱敏规则。模式、配置与导出面在前；实现内部细节放在下方可折叠的开发者章节中。
+`dsh-session-telemetry-otel` 仅在新的显式反馈后通过 OTel JS SDK 导出会话记录，适用于所有用户和提供方，包括 `deepseek-official`。`FEEDBACK_ONLY` 释放截至该反馈的权威日志前缀，包含上下文；后续记录等待下一次显式反馈。`DISABLED` 不构造传输。SDK 批处理可完成已授权的上传，无需另一次用户交互或模型调用。部署方负责脱敏规则。

-Capture runs in one of two modes. `live` capture follows session events as they are appended, replays already-live sessions at mount time, and records lifecycle markers; `on-demand` capture reads the canonical session log only when the backend requests a prefix through `captureSession(session, throughSeq?)`.

 ### The sharing disclosure
 
 <a id="the-sharing-disclosure"></a>
 
-Every backend discloses its deployment-selected sharing policy through the seam's `sharing` vocabulary: `full` (every event is handed over as it happens), `feedback-only` (nothing is handed over until a `feedback/record` event releases the unreleased prefix), or `disabled` (nothing is handed over at all). The policy API never claims delivery — handoff is the non-blocking enqueue, and batching, retry, and loss policy stay the backend SDK's.

 ### Capture flow
 
-Live capture registers, through the composing fiber's effects: `session/created` adopts the session and replays its lifecycle-local log suffix from the handoff cursor; `session/event` deep-copies, redacts, and hands off each event with zero I/O; `session/flush` forwards the optional hint and returns void so the loop's awaited parallel never waits on telemetry; `session/disposed` captures the session's `shutdown` marker and retires it; `agent/error` is the one live-bus relay, because the session-event vocabulary intentionally has no operational-error record. Disposal captures shutdown markers for still-live sessions, then awaits the backend's `shutdown()`. On-demand capture registers only the disposal effect and reads the requested lifecycle-local canonical-log prefix on request. Every synchronous handler runs inside containment so a failing backend or rule can never starve other listeners or reach the agent loop.
+Live capture registers Session events, flush hints, shutdown markers, and agent/error observers through the composing fiber’s effects. On-demand capture registers only the disposal effect and reads the requested canonical-log prefix under its history policy. Synchronous handlers contain failures so they cannot affect the agent loop or other listeners.
 
 ### The handoff cursor
 
-A module-scope `WeakMap<Session, seq>` records, per Session object, the highest seq handed off (not delivered). Live capture advances it at append time; on-demand capture advances it only while handing a requested prefix. Re-adopting the same object resumes after that cursor and does not duplicate its handed-off ledger records. A new Session object starts immediately before `firstLiveSeq`: a fresh object starts at seq 0, while a forked, resumed, or migrated object skips its constructor seed and starts with this lifecycle's `session/end-seed` boundary. This keeps inherited and previously persisted history outside a new lifecycle's sharing act. Receivers absorb SDK retries by deduplicating on `(session.id, session.format_version, event.seq)`. The object-keyed map is a narrow, documented exception to the registrations-are-effects discipline: entries die with their sessions, and losing one can replay only the current lifecycle suffix.
+A module-scope `WeakMap<Session, seq>` records the highest sequence handed off, not delivered. Re-adopting the same object resumes after that cursor. Capture normally starts at `firstLiveSeq`; explicit `includeHistory: true` starts an unhanded object at seq 0, including restored or fork history. The backend owns capture authorization. Stored history does not itself authorize capture; the OTel backend waits for new explicit feedback. Receivers deduplicate repeated records by `(session.id, session.format_version, event.seq)`.

Subject: [PATCH 21/70] fix(directory-picker-native): decode the Win32 picker
 path without a fixed 32KiB view

Replace the external ArrayBuffer view and manual UTF-16 scan with native Koffi decoding through a pointer-width buffer. Preserve the original address for CoTaskMemFree.

Exercise production resultPath with real Koffi decoding of live UTF-16 buffers. Cover zero-low-byte BMP characters, surrogate pairs, NUL termination, and strings exceeding 32 KiB; test four- and eight-byte BigInt pointer preservation and the original release address. A negative-control mutation confirms truncating a 64-bit address fails.

Keep the bilingual Agent Note focused on implementation rationale and required memory ownership. Preserve master archive seals during rebase.

+# Agent Note: Read the Win32 picker path without a fixed-size unmanaged view
+
+Status: implemented
+
+English | [中文](2026-08-31-win32-picker-path-string-read.zh.md)
+
+## Problem
+
+The Win32 picker needs to decode a NUL-terminated UTF-16 string allocated by `IShellItem::GetDisplayName` and release it through `CoTaskMemFree`. A fixed-length external ArrayBuffer adds a runtime requirement and manual terminator scanning without providing the allocation size.
+
+## Decision
+
+`readUtf16` stores the native address in a pointer-width buffer and passes it to generic `koffi.decode(buffer, 'str16')`. Generic decoding expects a pointer variable, not the string address directly. The slice follows `koffi.sizeof('void *')`; Koffi 3 represents native addresses as BigInt. The allocation must remain valid and NUL-terminated during decoding. Successful conversion leaves the original address available for `CoTaskMemFree`; if decoding throws, the string is not freed.
+
+## Alternatives considered
+
+**External view and manual scan.** This requires external-buffer support and duplicates Koffi's string conversion. Neither a fixed view nor growing chunks establish the native allocation size.
+
+**String-typed out-param.** `_Out_ str16 *` returns text but discards the pointer needed for explicit COM release. Built-in `str16!` disposal uses the CRT allocator rather than the COM allocator.
+
+**Custom disposable type.** A Koffi disposable can call `CoTaskMemFree`, but explicit conversion keeps the address and release at one call site without registering a native type.
+
+## Consequences
+
+Real-Koffi tests exercise the production result-path conversion over live UTF-16 buffers, including U+5F00, surrogate pairs, NUL termination and strings exceeding 32 KiB. Separate four- and eight-byte BigInt cases verify pointer preservation and release of the original address. Test-owned buffers stay live through the synchronous read; pointer bytes are checked before native dereferencing. The earlier scanning decision remains in the [archived note](../../archived/bug-fix/2026-08-23-win32-utf16-nul-truncation.md).

+# Agent Note: 不用固定长度的非托管视图读取 Win32 选择器路径
+
+Status: implemented
+
+[English](2026-08-31-win32-picker-path-string-read.md) | 中文
+
+## Problem
+
+Win32 选择器需要解码 `IShellItem::GetDisplayName` 分配的 NUL 结尾 UTF-16 字符串，并通过 `CoTaskMemFree` 释放它。固定长度的外部 ArrayBuffer 增加了运行时要求和手工终止符扫描，却不能提供实际分配大小。
+
+## Decision
+
+`readUtf16` 将原生地址存入指针宽度的缓冲区，再交给通用 `koffi.decode(buffer, 'str16')`。通用解码需要指针变量，而非直接传入字符串地址。切片长度取自 `koffi.sizeof('void *')`；Koffi 3 用 BigInt 表示原生地址。解码期间分配必须保持有效且以 NUL 结尾。转换成功后，原始地址仍可交给 `CoTaskMemFree`；若解码抛错，字符串不会被释放。
+
+## Alternatives considered
+
+**外部视图加手工扫描。** 这要求运行时支持外部缓冲区，并重复实现 Koffi 的字符串转换。固定视图和递增分块都无法确定原生分配大小。
+
+**字符串类型出参。** `_Out_ str16 *` 返回文本，却丢失显式 COM 释放所需的指针。内置 `str16!` 使用 CRT 分配器释放，而非 COM 分配器。
+
+**自定义可释放类型。** Koffi 可释放类型可以调用 `CoTaskMemFree`，但显式转换无需注册原生类型，就能将地址和释放保留在同一调用点。
+
+## Consequences
+
+真实 Koffi 测试使用存活的 UTF-16 缓冲区执行生产结果路径转换，涵盖 U+5F00、代理对、NUL 终止和超过 32 KiB 的字符串。独立的四字节与八字节 BigInt 用例验证指针保持完整，并释放原始地址。测试持有的缓冲区在同步读取期间保持存活；原生解引用之前会检查指针字节。此前的扫描决策保留在[归档记录](../../archived/bug-fix/2026-08-23-win32-utf16-nul-truncation.md)中。

+# Agent Note: Shared base default file editor selection
+
+Status: implemented
+
+English | [中文](2026-09-05-base-default-file-editor.zh.md)
+
+## Problem
+
+The shared base selects both `read`/`write`/`edit` and `str_replace_editor`, which offer overlapping file editing interfaces. [Issue #3599](https://github.com/deepseek-harness/deepseek-harness/issues/3599) requests one default interface for base-backed profiles while preserving the dedicated minimal compositions.
+
+## Decision
+
+The [base patch](../../../../packages/bundle/base/cordis.patch.yml) selects `read`, `write`, and `edit` for file editing. It does not insert `tool-str-replace-editor`; SDK and Web application patches therefore need no disabling override. The editor package remains available to compositions that insert it explicitly.
+
+[Web minimal](../../../../packages/preset/agent-presets/presets/minimal/agent.cordis.yml) inserts its own `str-replace-editor` row in the agent scope. The standalone [sdk-minimal bundle](../../../../packages/bundle/sdk-minimal/cordis.patch.yml) inserts its own row without inheriting base. Both minimal compositions retain their editor.
+
+This refines the shared tool defaults in [one dsh launcher](../architecture/2026-08-22-single-dsh-application-launcher.md). That note remains active for launch ownership, shared services, and patch precedence; no active note is fully superseded.
+
+## Alternatives considered
+
+**Disable the editor separately in each application.** This leaves overlapping defaults in base and requires each consumer to opt out. The base owns the shared choice directly.
+
+**Delete the tool package or remove it from minimal.** The dedicated minimal compositions use this interface for file operations. Keeping the package and their explicit rows preserves that behavior.
+
+## Consequences
+
+Base-backed SDK, headless, ACP, and custom profiles omit the editor schema by default. Web standard also omits it. A profile, home, or invocation patch can add the tool with `insert`; a patch that only sets `disabled: false` requires an existing row and cannot create one. This decision does not make all SDK and Web tools identical.
+
+## Verification
+
+The [SDK process tests](../../../../apps/cli/tests/profiles/sdk/keyless-smoke.e2e.ts) capture actual model requests for default file tools, explicit editor insertion, and the standalone minimal roster. The [headless process test](../../../../apps/cli/tests/profiles/headless/tests/keyless-smoke.e2e.ts) checks the shared default through its application. [Web minimal snapshots](../../../../apps/web/tests/minimal-preset.snapshot.ts) exercise the editor through the minimal preset. The [headless](../../../../snapshots/session/headless.snapshot.ts), [SDK](../../../../snapshots/sdk/sdk.snapshot.ts), and [ACP](../../../../snapshots/acp/acp.snapshot.ts) recorded sessions pin the assembled model-visible outputs, including the SDK fixture that explicitly inserts the editor.

+# Agent Note: 共享 base 默认文件编辑器选择

+[English](2026-09-05-base-default-file-editor.md) | 中文
+
+## Problem
+
+共享 base 同时选择 `read`/`write`/`edit` 和 `str_replace_editor`，这些工具提供重叠的文件编辑接口。[Issue #3599](https://github.com/deepseek-harness/deepseek-harness/issues/3599) 要求基于 base 的 profile 默认使用一套接口，同时保留专用的极简组合。
+
+## Decision
+
+[base patch](../../../../packages/bundle/base/cordis.patch.yml) 选择 `read`、`write` 和 `edit` 负责文件编辑。它不插入 `tool-str-replace-editor`；因此 SDK 与 Web 应用 patch 无需禁用覆盖。编辑器包仍可供显式插入它的组合使用。
+
+[Web minimal](../../../../packages/preset/agent-presets/presets/minimal/agent.cordis.yml) 在 agent 作用域插入自己的 `str-replace-editor` 配置项。独立的 [sdk-minimal bundle](../../../../packages/bundle/sdk-minimal/cordis.patch.yml) 不继承 base，自行插入配置项。两种极简组合都保留其编辑器。
+
+本决策细化了[统一 dsh 启动器](../architecture/2026-08-22-single-dsh-application-launcher.zh.md)中的共享工具默认值。该文档对启动所有权、共享服务和 patch 优先级仍然有效；没有被完全取代的活跃 Agent Note。
+
+## Alternatives considered
+
+**在每个应用中分别禁用编辑器。** 这会在 base 中保留重叠的默认接口，并要求各消费方主动退出。共享选择由 base 直接负责。
+
+**删除工具包或从 minimal 移除它。** 专用的极简组合通过此接口完成文件操作。保留包及其显式配置项可以保留这一行为。
+
+## Consequences
+
+基于 base 的 SDK、headless、ACP 与自定义 profile 默认不包含该编辑器 schema。Web standard 同样不包含它。profile、home 或逐次调用 patch 可以通过 `insert` 添加工具；只设置 `disabled: false` 的 patch 需要已有配置项，无法创建配置项。本决策不要求 SDK 与 Web 的全部工具一致。
+
+## Verification
+
+[SDK 进程测试](../../../../apps/cli/tests/profiles/sdk/keyless-smoke.e2e.ts) 捕获默认文件工具、显式插入编辑器与独立极简工具清单的实际模型请求。[headless 进程测试](../../../../apps/cli/tests/profiles/headless/tests/keyless-smoke.e2e.ts) 通过所属应用检查共享默认值。[Web minimal 快照](../../../../apps/web/tests/minimal-preset.snapshot.ts) 通过极简 preset 执行编辑器。[headless](../../../../snapshots/session/headless.snapshot.ts)、[SDK](../../../../snapshots/sdk/sdk.snapshot.ts) 与 [ACP](../../../../snapshots/acp/acp.snapshot.ts) 录制会话固定组装后模型可见的输出，包括显式插入编辑器的 SDK fixture。

-English | [中文](2026-09-05-sdk-default-file-editor.zh.md)
-
-## Problem
-
-The standard SDK profile inherits both `read`/`write`/`edit` and `str_replace_editor` from the shared base. These offer overlapping file editing interfaces, while the Web standard preset selects the former. [Issue #3599](https://github.com/deepseek-harness/deepseek-harness/issues/3599) requests the same editor choice for the standard SDK without making all SDK and Web behavior identical.
-
-## Decision
-
-The [SDK application patch](../../../../packages/bundle/sdk-app/cordis.patch.yml) disables the inherited `tool-str-replace-editor` row. The SDK retains `read`, `write`, and `edit`; the shared base, reusable editor package, and standalone `sdk-minimal` composition retain their own defaults. A trusted profile, home, or invocation patch can explicitly enable the row.
-
-This narrows the SDK tool default described by [one dsh launcher](../architecture/2026-08-22-single-dsh-application-launcher.md). That decision remains active for launch ownership, shared services, and patch precedence; no active note is fully superseded.
-
-## Alternatives considered
-
-**Keep both editors enabled.** Shared base composition explains their availability, but the standard SDK does not need two default interfaces for the same file editing operations. Callers requiring this editor can select it explicitly.

-**Remove the shared registration or reuse the entire Web preset.** Either changes more than the requested SDK default. Keeping the change in the SDK bundle preserves other profiles and the existing application architecture.
-
-## Consequences
-
-Default SDK requests omit the editor schema. Callers that select `str_replace_editor` by name need an explicit patch or their existing dedicated composition. This decision makes no claim of complete SDK/Web tool parity.
-
-## Verification
-
-The [SDK profile process test](../../../../apps/cli/tests/profiles/sdk/keyless-smoke.e2e.ts) captures actual model requests for the default roster, explicit editor enablement, and standalone minimal roster. [SDK recorded sessions](../../../../snapshots/sdk/sdk.snapshot.ts) pin the resulting schemas; shared cross-profile and persistent-editor recordings explicitly retain their required editor.

-# Agent Note: SDK 默认文件编辑器选择
-
-Status: implemented
-
-[English](2026-09-05-sdk-default-file-editor.md) | 中文
-
-## Problem
-
-标准 SDK profile 从共享 base 同时继承 `read`/`write`/`edit` 和 `str_replace_editor`。这些工具提供重叠的文件编辑接口，而 Web standard preset 选择前者。[Issue #3599](https://github.com/deepseek-harness/deepseek-harness/issues/3599) 要求标准 SDK 采用相同的编辑器选择，不要求 SDK 与 Web 的全部行为一致。
-
-## Decision
-
-[SDK 应用 patch](../../../../packages/bundle/sdk-app/cordis.patch.yml) 禁用继承的 `tool-str-replace-editor` 配置项。SDK 保留 `read`、`write` 和 `edit`；共享 base、可复用编辑器包及独立 `sdk-minimal` 组合保留各自的默认值。受信任的 profile、home 或逐次调用 patch 可以显式启用该配置项。
-
-本决策收窄了[统一 dsh 启动器](../architecture/2026-08-22-single-dsh-application-launcher.zh.md)所述的 SDK 工具默认值。该决策对启动所有权、共享服务和 patch 优先级仍然有效；没有被完全取代的活跃 Agent Note。
-
-## Alternatives considered
-
-**继续默认启用两个编辑器。** 共享 base 组合解释了它们为何可用，但标准 SDK 无需为相同的文件编辑操作默认提供两套接口。需要此编辑器的调用方可以显式选择它。
-
-**移除共享注册或复用整个 Web preset。** 两者都会扩大 SDK 默认值调整的范围。将改动放在 SDK bundle 中可以保留其他 profile 和现有应用架构。
-
-## Consequences
-
-默认 SDK 请求省略该编辑器 schema。按名称选择 `str_replace_editor` 的调用方需要显式 patch 或其现有专用组合。本决策不承诺 SDK/Web 的全部工具一致。
-
-## Verification
-
-[SDK profile 进程测试](../../../../apps/cli/tests/profiles/sdk/keyless-smoke.e2e.ts) 捕获默认工具清单、显式启用编辑器和独立极简工具清单的实际模型请求。[SDK 录制会话](../../../../snapshots/sdk/sdk.snapshot.ts) 固定最终 schema；跨 profile 共享录制与持久编辑器录制显式保留其所需的编辑器。

 Out of the box, every profile built on this core provides: a DeepSeek model connection (the provider and model are configurable, and you can enable extra providers from your settings), the full tool set — file editing, shell commands, web search, public HTTP(S) fetch, subagents, task and goal tracking — durable sessions that survive restarts, and the default permission policy that confines file writes to your workspace and asks before risky actions. Web fetch runs without per-call approval; its provider rejects non-public destinations. Telemetry stays off unless you opt in.
 
+Default file editing uses `read`, `write`, and `edit`. The optional `str_replace_editor` tool is selected independently by Web minimal and `sdk-minimal`. To add it to a base-backed profile, put this entry in the profile, home, or invocation patch:
+
+```yaml
+- insert:
+    - id: tool-str-replace-editor
+      name: '@deepseek-ai/dsh-tool-str-replace-editor'
+      config:
+        maxOutputChars: 16000
+```
+
 ### Shell tools per platform
 
 On macOS and Linux you get the bash shell tools; on Windows you get the PowerShell twins instead, so exactly one shell stack is available per machine. The safety behavior is identical on every platform. A Windows host that prefers the unconfined PowerShell executor can switch the shell rows in its profile patch — the switch must disable both PowerShell rows and re-enable both bash rows, otherwise the profile fails to load.

 `tools/post-execute` has two mutually exclusive successful projections. Replacing `content` changes only Native/model presentation and preserves the canonical value and metadata. Replacing `value` revalidates the replacement and recomputes both presentation projections. A block removes the value and becomes a failure. Content replacement is therefore not a confidentiality mechanism: policy that must prevent programmatic access blocks the call or replaces the value.
 
-Canonical values are execution-local. The agent loop persists `tool/result` with only `content`, `error`, and optional `meta`; PTC mode's `tool/code-dispatch` persists the sub-call's rendered `content` and `isError`. Neither event stores the canonical intermediate value, so replay reproduces presentation but cannot reconstruct the programmatic result. When a tool declares `presentationMeta`, it is computed only for a direct surface call; a nested Code dispatch gets no metadata or result card. The outer `run_code` card instead reads final post-policy content and declares no presentation metadata. Generic and tool-owned spill projections similarly skip nested dispatches, whose canonical value never enters model context.

+# Agent Note: Nested terminal cards
+
+Status: implemented
+
+English | [中文](2026-09-05-nested-terminal-cards.zh.md)
+
+## Problem
+
+A shell command dispatched through `run_code` carries the arguments and rendered output needed for a terminal card, but rejecting every block with `parentCallId` hides that presentation solely because the call is nested. The rejection also affects running prompts and selected-child Details.
+
+## Decision
+
+`terminalCardModel` applies the same eligibility checks to root and Code Dispatch calls, without rejecting `parentCallId`. Supported running and settled `bash`, `pwsh`, and `terminal_send` calls use the existing terminal card. Background calls, tool errors, malformed inputs, missing call heads, and unsupported result content retain generic fallback. Persistent shells remain eligible while running and generic when settled; a nonzero process exit remains terminal result data rather than a tool error.
+
+This partially supersedes only the terminal child-card prohibition in [Client-derived tool presentation](../architecture/2026-08-23-client-derived-tool-presentation.md). That note remains active for Client presentation ownership and the diff/read/search/web child restrictions. No Host presenter, event, schema, metadata, call-tree, or model-context change is required. The metadata and execution-local value decisions in [canonical tool output](../architecture/2026-07-20-canonical-tool-output-contract.md) and [PTC typed returns](../feature/2026-07-20-ptc-typed-tool-returns.md) remain intact; metadata omission does not prohibit Client-derived terminal cards.
+
+## Alternatives considered
+
+**Keep the blanket nested-call rejection.** Rejected because nesting does not remove the raw facts the terminal model already consumes. It hides usable shell output while the same call renders as a terminal at the root.
+
+**Enable every nested structured card.** Rejected because other card models have independent metadata requirements and child restrictions. This fix changes only terminal eligibility.
+
+## Consequences
+
+Rows and Details share terminal derivation for nested calls without a second renderer or presentation hint. Generic fallback and settled-persistent behavior remain separate from terminal-card eligibility. The parent-child relationship still controls tree placement, not terminal rendering.
+
+## Verification
+
+The [terminal card specs](../../../../packages/client/ui-tool/tests/terminal-card.client.spec.tsx) cover root/child eligibility, running and settled Details, and fallback cases. The [assembled Code Dispatch specs](../../../../packages/client/ui-tool/tests/chat-code-subcalls.client.spec.tsx) cover nested terminal rendering through the conversation tree. Browser replay owns the visible nested-card change; nonterminal child behavior remains outside this fix.

+
+## 问题
+
+经 `run_code` 分发的 shell 命令携带 terminal 卡片所需的参数与渲染输出，但对所有带有 `parentCallId` 的块一律拒绝，会仅因调用嵌套而隐藏这类展示。该拒绝也影响运行中的命令提示行与选中子调用的 Details。
+
+## 决策
+
+`terminalCardModel` 对根调用与 Code Dispatch 调用应用相同的适用检查，不因 `parentCallId` 拒绝调用。受支持的运行中与已完成的 `bash`、`pwsh` 和 `terminal_send` 调用使用现有 terminal 卡片。后台调用、工具错误、格式错误的输入、缺失的调用头和不受支持的结果内容保留通用回退。持久 shell 在运行中仍可使用 terminal，完成后使用通用展示；非零进程退出仍是 terminal 结果数据，而非工具错误。
+
+本文仅部分取代 [Client 派生工具展示](../architecture/2026-08-23-client-derived-tool-presentation.zh.md)中的 terminal 子调用卡片禁令。该文继续负责 Client 展示所有权及 diff/read/search/web 子调用限制。无需更改 Host 展示转换器、事件、schema、元数据、调用树或模型上下文。[规范工具输出](../architecture/2026-07-20-canonical-tool-output-contract.zh.md)与 [PTC 类型化返回值](../feature/2026-07-20-ptc-typed-tool-returns.zh.md)中的元数据和执行期值决策保持不变；省略元数据不禁止 Client 派生 terminal 卡片。
+
+## 考虑过的替代方案
+
+**保留对嵌套调用的一律拒绝。** 不予采用，因为嵌套不会移除 terminal model 已消费的原始事实。这会隐藏可用的 shell 输出，而同一调用位于根时却可渲染为 terminal。
+
+**启用所有嵌套结构化卡片。** 不予采用，因为其他 card model 有独立的元数据要求与子调用限制。本修复只改变 terminal 适用性。
+
+## 后果
+
+行与 Details 对嵌套调用共享 terminal 派生，不增加第二个渲染器或展示提示字段。通用回退与已完成持久 shell 的行为仍独立于 terminal 卡片适用性。父子关系仍控制树中的位置，而非 terminal 渲染。
+
+## 验证
+
+[Terminal 卡片测试](../../../../packages/client/ui-tool/tests/terminal-card.client.spec.tsx)覆盖根／子调用适用性、运行中与已完成的 Details 以及回退情况。[组装后的 Code Dispatch 测试](../../../../packages/client/ui-tool/tests/chat-code-subcalls.client.spec.tsx)覆盖经对话树渲染的嵌套 terminal。浏览器回放负责验证可见的嵌套卡片变化；非 terminal 子调用行为不属于本修复。

 This partially supersedes only the terminal child-card prohibition in [Client-derived tool presentation](../architecture/2026-08-23-client-derived-tool-presentation.md). That note remains active for Client presentation ownership and the diff/read/search/web child restrictions. No Host presenter, event, schema, metadata, call-tree, or model-context change is required. The metadata and execution-local value decisions in [canonical tool output](../architecture/2026-07-20-canonical-tool-output-contract.md) and [PTC typed returns](../feature/2026-07-20-ptc-typed-tool-returns.md) remain intact; metadata omission does not prohibit Client-derived terminal cards.
 
+Shell output ending in a recognized spill-policy notice uses generic output: expandable in `BashRow`, raw fallback in Details. The notice can follow or replace the exit marker, so its absence at the end does not justify a successful terminal status. The Client recognizes the final notice without changing Host output or schemas.
+
 ## Alternatives considered
 
 **Keep the blanket nested-call rejection.** Rejected because nesting does not remove the raw facts the terminal model already consumes. It hides usable shell output while the same call renders as a terminal at the root.
 
 **Enable every nested structured card.** Rejected because other card models have independent metadata requirements and child restrictions. This fix changes only terminal eligibility.
 
+**Parse exit markers around spill suffixes.** Rejected because truncation can remove the real status; conservative generic output avoids guessing success from an incomplete result.
+
 ## Consequences
 
 Rows and Details share terminal derivation for nested calls without a second renderer or presentation hint. Generic fallback and settled-persistent behavior remain separate from terminal-card eligibility. The parent-child relationship still controls tree placement, not terminal rendering.

+以已识别的 spill 策略提示结尾的 shell 输出使用通用展示：在 `BashRow` 中可展开，在 Details 中使用原始回退。提示可能位于退出标记之后或取代它，因此末尾缺少退出标记不能作为 terminal 成功状态的依据。Client 识别最终提示，不更改 Host 输出或 schema。
+
 ## 考虑过的替代方案
 
 **保留对嵌套调用的一律拒绝。** 不予采用，因为嵌套不会移除 terminal model 已消费的原始事实。这会隐藏可用的 shell 输出，而同一调用位于根时却可渲染为 terminal。
 
 **启用所有嵌套结构化卡片。** 不予采用，因为其他 card model 有独立的元数据要求与子调用限制。本修复只改变 terminal 适用性。
 
+**解析 spill 后缀附近的退出标记。** 不予采用，因为截断可能移除真实状态；保守的通用输出避免从不完整结果猜测成功。
+
 ## 后果
 
 行与 Details 对嵌套调用共享 terminal 派生，不增加第二个渲染器或展示提示字段。通用回退与已完成持久 shell 的行为仍独立于 terminal 卡片适用性。父子关系仍控制树中的位置，而非 terminal 渲染。

-This package owns the generic fallback and the built-in shell/pwsh, read, read_image, write/edit, running `str_replace_editor` `create`/`str_replace`, grep/glob, web, todo, question, and Code Dispatch presentations. Structured cards derive directly from first-party raw event fields; Host `presentCall` and `presentResult` values never enter the Client. Running and settled foreground `bash`, `pwsh`, and `terminal_send` calls use terminal cards at the root and in Code Dispatch children, subject to the same argument, result, and error checks. Settled persistent-shell results stay generic because reset and partial-output diagnostics do not always describe one process exit status; root persistent results are expandable, while background acknowledgements remain collapsed. A successful question row pairs call questions with result answers by their stable ids and shows readable question/answer lines when expanded. A cancelled or interrupted row shows its verdict and original questions without inventing answers. Unsupported, malformed, or ambiguous inputs fall back to flattened Tool input/result text. `ui-skill` demonstrates a business-owned registration for `skill`.

The notice can follow or replace the exit marker, so its absence at the end does not justify a successful terminal status. The browser-safe `@deepseek-ai/dsh-spill-policy/notice` entry owns the text convention: the producer calls `formatSpillNotice(omitted, ref)` and the Client calls `hasSpillNotice(text)`. Both share delimiters, and omission validation reuses `describeOmitted` rather than duplicating its prose. The formatter preserves the persisted spelling byte-for-byte; existing Session result bytes stay untouched, with no Session format change or migration.

 **Parse exit markers around spill suffixes.** Rejected because truncation can remove the real status; conservative generic output avoids guessing success from an incomplete result.
 
+**Maintain a separate UI notice regex.** Rejected because it duplicates the producer's text convention and can drift from persisted output. The shared browser-safe owner keeps formatting and recognition together without loading the Host plugin in the browser.
+
 ## Consequences
 
-Rows and Details share terminal derivation for nested calls without a second renderer or presentation hint. Generic fallback and settled-persistent behavior remain separate from terminal-card eligibility. The parent-child relationship still controls tree placement, not terminal rendering.

 The package fills `conversation.details.tool` with `ToolDetails`. Row and Details renderers share one pure card model for each terminal, read, diff, search, and web card; the image card is row-only because its gallery renders through the tool-owned `tool.call.images` slot the details panel does not declare. These models validate raw call arguments, result content, failure state, persisted metadata, and Session path facts. Diff, read, search, and web models also reject Code Dispatch children; terminal eligibility does not depend on `parentCallId`. Unsupported or malformed inputs use flattened Tool result text. Card-specific limits and fallback rules for the terminal, diff, read, search, and web cards remain in [the ui-primitives README](../ui-primitives/README.md); the image card's model in this package carries its own fallback rules.
+
+The terminal model uses `hasSpillNotice` from the browser-safe `@deepseek-ai/dsh-spill-policy/notice` entry, not an independent UI pattern. The [spill-policy README](../../spill/spill-policy/README.md#shared-notice-ownership) owns notice formatting and recognition. This check conservatively selects generic output; matching text cannot authenticate its source, and replay leaves recorded result bytes untouched.

+### Shared notice ownership
+
+The browser-safe `@deepseek-ai/dsh-spill-policy/notice` entry owns both `formatSpillNotice(omitted, ref)`, used by the producer, and `hasSpillNotice(text)`, used by presentation consumers. Formatting and recognition share the notice delimiters; omission validation uses the existing `describeOmitted` formatter rather than a second copy of its prose. Recognition accepts a complete final notice after a preview or by itself and preserves the persisted notice spelling. It reads recorded text without rewriting it.

Subject: [PATCH 28/70] test(perf): gate opening large Sessions with synthetic
 CI benchmarks

Add a benchmark lane (`vitest.bench.config.ts`, `pnpm run test:bench`,
gate mode `ci-bench`) and a required `node 24 / benchmarks` CI job that
runs it alone. Benchmarks synthesize their input in-process from fixed
parameters and fail on documented budgets:

- `open-generation.bench.ts`: a 200-turn released-v0 log with 500 text
  and 125 reasoning deltas per reply (127,400 events, ~2.8 MB) encoded
  through the frozen v0 codec; the migrating first `open()` must finish
  within 2,000 ms in a child process capped at 128 MB of old space, and a
  fresh process must open the published current generation within 500 ms.
- `conversation-fold.bench.client.ts`: 200 replies whose compact streams
  hold 2,000 text + 500 reasoning deltas each, folded through every Chat
  Definition by the real assembler; the fold must finish within 150 ms
  and stay within 3x the fold of the same window with 100 deltas per
  reply.

On this commit both gates fail: the migration exhausts the 128 MB heap
(4.8 s and 696 MB peak RSS without the cap; the pre-stack decode of the
same bytes took 34 ms and 168 MB) and the fold scales 11x with the delta
count. The stacked fixes bring both paths to O(records).

+# Agent Note: Required CI performance gate for opening large Sessions
+
+Status: implemented
+
+English | [中文](2026-09-04-session-open-performance-gate.zh.md)
+
+## Problem
+
+The Session format v2 rollout changed two paths whose cost scales with model output: the JSONL backend migrates and publishes a released-v0 log on its first `open()`, and the Client folds each settled reply's embedded compact stream. Neither path had an executed performance check, so a first open that grew from about 35 ms to about 5 s on a 127,400-event synthetic log (and from about 0.3 s to 26 s on a 575,000-chunk real log, with peak RSS of 2.7 GB and heap exhaustion under a 512 MB limit) and a Client fold that grew linearly with streamed deltas instead of compact records both reached master unnoticed. Unit tests use small logs, the coverage gate measures lines, and the existing `test:web:perf` inventory is a manual diagnostic outside CI.
+
+## Decision
+
+Linux pull requests run a required `node 24 / benchmarks` job that executes `pnpm run check:ci:bench` → `pnpm run test:bench` → `vitest.bench.config.ts`, which collects `packages/*/*/tests/**/*.bench.ts` and `*.bench.client.ts` and runs one file at a time. The job runs the benchmark lane alone, on the same runner selector and failover switch as the other required Linux workers, and joins the `all checks passed` verdict.
+
+Every benchmark synthesizes its input in-process from fixed parameters: numbered prompts, counter tokens, fixed timestamps. Recorded Sessions are never used because they carry user content, differ between machines, and drift as fixtures are re-recorded. Each benchmark documents its budget beside the constant that enforces it, and budgets follow three rules: a wall-clock budget sits a small multiple above the intended cost and well below the regression it guards; a memory budget runs the measured path in a child Node process under a fixed `--max-old-space-size`, so an allocation regression fails as an out-of-memory exit regardless of the runner's physical memory; and a scaling assertion compares two sizes of the same workload so a complexity regression fails on any host speed.
+
+The first two gates cover the two regressed paths:
+
+| Benchmark | Workload | Gates |
+|---|---|---|
+| `packages/session/session-persistence-jsonl/tests/open-generation.bench.ts` | 200 turns × (500 text + 125 reasoning deltas) = 127,400 released-v0 events, about 2.8 MB, encoded through the frozen v0 codec with packed rows | migrating first `open()` ≤ 2,000 ms under a 128 MB heap; fresh-process open of the published current generation ≤ 500 ms; minimum of three attempts |
+| `packages/client/ui-chat/tests/conversation-fold.bench.client.ts` | 200 replies whose compact streams hold 2,000 text + 500 reasoning deltas each (500,000 deltas in 1,600 records), folded through every Chat Definition by the real `ConversationNodeAssembler` | large fold ≤ 150 ms; large fold ≤ 3× the fold of the same window with 100 deltas per reply |
+
+Measured on the reference machine at the commit that introduced the gate, the migration benchmark exhausted the 128 MB heap and the fold benchmark scaled 11× between the small and large windows, so both gates fail on the regressed code and pass once the paths do O(records) work.
+
+## Alternatives considered
+
+**Extend the manual `test:web:perf` inventory.** Rejected: it stays outside CI by design, measures a simplified fold rather than the registered Definitions, and asserts nothing.
+
+**Time-only budgets.** Rejected: a single absolute budget either fails on slower runners or passes a regression on faster ones; the heap cap and the scaling ratio give host-independent verdicts, and the wall-clock budget remains as the timeout that the user-visible symptom is about.
+
+**Benchmark the real recorded corpus.** Rejected: corpus fixtures are small by policy, recorded material must not become a benchmark input, and their re-recording would silently move the baseline.
+
+**Run the benchmarks inside an existing gate aggregate.** Rejected: aggregates run gates concurrently on one runner, so wall-clock measurements would inherit the neighbours' CPU load.
+
+## Consequences
+
+Every pull request pays one more required Linux job of a few minutes, dominated by install time rather than the benchmarks themselves. A change that makes first open or the Client fold slower than its budget, heavier than its heap limit, or proportional to streamed deltas fails in the PR that introduces it, with the measured numbers printed in the job log. A budget change is a reviewed edit of the constant and its rationale comment, never an environment override, and a new benchmark must state which owner-visible path and which regression class it guards. The gate does not measure browser rendering, network transfer, or real recorded Sessions; those remain covered by the manual `test:web:perf` inventory and by review.

+# Agent Note: 打开大型 Session 的必需 CI 性能 gate
+
+Status: implemented
+
+[English](2026-09-04-session-open-performance-gate.md) | 中文
+
+## 问题
+
+Session format v2 的推出改变了两条成本随模型输出增长的路径：JSONL backend 在首次 `open()` 时迁移并发布 released-v0 log，Client 则 fold 每个已结算回复中嵌入的紧凑 stream。两条路径都没有可执行的性能检查，因此首次打开在 127,400 事件的合成 log 上从约 35 ms 增长到约 5 s（在 575,000 chunk 的真实 log 上从约 0.3 s 增长到 26 s，峰值 RSS 2.7 GB，并在 512 MB 堆限制下耗尽堆），以及 Client fold 随流式 delta 数而不是紧凑记录数线性增长，都未被察觉地进入了 master。单元测试使用小 log，coverage gate 只度量行数，现有的 `test:web:perf` 清单是 CI 之外的手动诊断。
+
+## 决定
+
+Linux pull request 运行必需的 `node 24 / benchmarks` job，执行 `pnpm run check:ci:bench` → `pnpm run test:bench` → `vitest.bench.config.ts`，后者收集 `packages/*/*/tests/**/*.bench.ts` 与 `*.bench.client.ts` 并逐文件运行。该 job 单独运行基准 lane，与其他必需 Linux worker 使用同一 runner 选择器和 failover 开关，并加入 `all checks passed` 判定。
+
+每个基准都在进程内按固定参数合成输入：编号的 prompt、计数 token、固定时间戳。绝不使用录制的 Session，因为它们携带用户内容、在不同机器上不同，并随 fixture 重新录制而漂移。每个基准在强制执行预算的常量旁记录其预算，预算遵循三条规则：壁钟预算取目标成本的小倍数并远低于所防护的回归；内存预算把被测路径放在固定 `--max-old-space-size` 的子 Node 进程中运行，使分配回归无论 runner 物理内存多大都以 out-of-memory 退出失败；缩放断言比较同一负载的两个规模，使复杂度回归在任何主机速度下都失败。
+
+前两个 gate 覆盖两条回归路径：
+
+| 基准 | 负载 | Gate |
+|---|---|---|
+| `packages/session/session-persistence-jsonl/tests/open-generation.bench.ts` | 200 轮 ×（500 text + 125 reasoning delta）= 127,400 个 released-v0 事件，约 2.8 MB，经冻结 v0 codec 以 packed row 编码 | 迁移的首次 `open()` 在 128 MB 堆下 ≤ 2,000 ms；新进程打开已发布 current generation ≤ 500 ms；三次尝试取最小值 |
+| `packages/client/ui-chat/tests/conversation-fold.bench.client.ts` | 200 个回复，每个紧凑 stream 含 2,000 text + 500 reasoning delta（1,600 条记录中 500,000 个 delta），由真实 `ConversationNodeAssembler` 经全部 Chat Definition fold | 大窗口 fold ≤ 150 ms；大窗口 fold ≤ 每回复 100 delta 的同一窗口的 3 倍 |
+
+在引入该 gate 的提交上于参考机器测得：迁移基准耗尽 128 MB 堆，fold 基准在小窗口与大窗口之间缩放 11 倍，因此两个 gate 都在回归代码上失败，并在两条路径改为 O(records) 工作后通过。
+
+## 考虑过的替代方案
+
+**扩展手动 `test:web:perf` 清单。** 拒绝：它有意留在 CI 之外，测量的是简化 fold 而非已注册的 Definition，且不做任何断言。
+
+**只用时间预算。** 拒绝：单一绝对预算要么在较慢的 runner 上失败，要么在较快的 runner 上放过回归；堆上限与缩放比给出与主机无关的判定，壁钟预算则作为用户可见症状所对应的超时保留。
+
+**用真实录制语料做基准。** 拒绝：语料 fixture 按策略保持小体量，录制材料不得成为基准输入，且其重新录制会静默移动基线。
+
+**把基准放进现有 gate 聚合中运行。** 拒绝：聚合在一个 runner 上并发运行各 gate，壁钟测量会继承邻居的 CPU 负载。
+
+## 后果
+
+每个 pull request 多付出一个几分钟的必需 Linux job，其时间主要花在安装而不是基准本身。让首次打开或 Client fold 慢于预算、重于堆限制或与流式 delta 数成正比的改动，会在引入它的 PR 中失败，并把测得的数字打印在 job 日志里。预算变更是对常量及其理由注释的受评审编辑，绝不是环境变量覆盖；新增基准必须说明它防护哪条 owner 可见路径和哪类回归。该 gate 不测量浏览器渲染、网络传输或真实录制的 Session；这些仍由手动 `test:web:perf` 清单和评审覆盖。

Per-file 100% on `packages/shell/pwsh-local/src` needs a real `pwsh`: without one its executor suites self-skip and `vitest.config.ts` exempts the file so pwsh-less hosts stay green, while CI runners ship pwsh and enforce the full bar.
 - **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
 - **Owner-local expected output** (`pnpm run test:expected`): keyless assembled CLI/process expectations without a recorded-session round trip. Drivers use `*.expected.e2e.ts` beside `tests/expected/`; CI runs built exports. Package/script expectations use `test`, while browser expectations use `test:web`.
+- **Performance benchmarks** (`pnpm run test:bench`; required Linux PR gate `node 24 / benchmarks`): `*.bench.ts` and Client-face `*.bench.client.ts` files under `packages/*/*/tests/` synthesize input from fixed parameters, never recorded material, and fail on a documented wall-clock budget, heap limit, or scaling ratio ([rules and current gates](../.agents/notes/implemented/testing/2026-09-04-session-open-performance-gate.md)).
 - **Snapshot** (`pnpm run test:snapshot`): a top-level scenario's highest recorded parent generation supplies user input and model replay, then serves as the expected persisted result. Parent filenames are `session[.vN].jsonl`; child roles are `session.<ordinal>[.vN].jsonl`; v0 omits `.v0`, positive versions require lowercase `.vN`, and each filename must agree with its header. Process scenarios start through `dsh`: headless owns one-shot behavior, the SDK owns persistent control, ACP owns automation-protocol behavior, and Web retains browser/ARIA evidence beside the same Session. `snapshot.yml` declares the profile, composition/header class, recording policy, exceptional replay or input metadata, and workspace facts. Typed tokens preserve parent/child identity relationships; only header pins own prompt/schema sidecars. A mutating scenario independently compares the complete `workspace.expected/` tree, which record and refresh never rewrite. Use `test:snapshot:record` when a model transcript changes and `test:snapshot:refresh` when replay input remains valid; review every resulting diff.
 - **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares session-driven output under `snapshots/web/` and UI-only output under `apps/web/tests/expected/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` builds first for plugin CSS.
 
-Session fixtures retain headers and payloads but omit body sequence/time envelopes; replay synthesizes them. Replay, record, and refresh select each parent/child role's highest generation. Current v2 uses `.v2`, one row per event, and embedded compact Assistant streams; retained v0 (suffixless) and v1 (`.v1`) may keep canonical packed rows for migration coverage. [The migrator](../scripts/migrate-packed-session-fixtures.ts) rewrites older historical layouts.

 ## How specs execute
 
-Forked workers run several spec files at once, the coverage gate splits into concurrent partitions beside the other gates in its job, and the self-hosted runners share one host and one volume. Only the process is isolated: ports, predictable paths, external namespaces, and inherited children are not. Own each acquired resource through its teardown, and read a spec that passes only when it runs alone as a defect in the spec rather than an unstable runner. [dsh-ci-test-reliability](../.agents/skills/dsh-ci-test-reliability/SKILL.md) owns the allocation, restoration, synchronization, timeout-budget, platform, and teardown rules; its [flake diagnosis workflow](../.agents/skills/dsh-ci-test-reliability/references/ci-flake-diagnosis.md) classifies an existing probabilistic failure.

 - **覆盖率门禁**（`pnpm run test:coverage`）：门禁级运行，对 `packages/*/*/src` 按文件 100% 覆盖。未覆盖的行往往是门禁正确标记出的死代码（应删除），而非需要补写的测试。行覆盖率是必要条件，但永远不是充分条件：它证明行被执行过，不证明功能按交付预期工作。`packages/shell/pwsh-local/src` 的按文件 100% 覆盖需要真实的 `pwsh`：缺少它时其执行器套件会自动跳过，`vitest.config.ts` 会豁免该文件以使无 pwsh 的主机保持绿色，而 CI runner 自带 pwsh，仍按完整标准执行门禁。
 - **真实 API e2e**（`pnpm run test:e2e`）：带密钥测试调用真实提供方 API，包括 DeepSeek 模型以及各提供方特有的冒烟测试；这些测试各自由自己的密钥控制（`EXA_API_KEY`、`PERPLEXITY_API_KEY` 等），缺少密钥时套件会自动跳过，使 keyless CI 保持绿色（[真实 API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.zh.md)）。
 - **所属位置的预期输出**（`pnpm run test:expected`）：无录制会话往返的无密钥组装 CLI/进程预期。驱动使用 `*.expected.e2e.ts`，并与 `tests/expected/` 同属一处；CI 针对构建产物运行。包/脚本预期使用 `test`，浏览器预期使用 `test:web`。
+- **性能基准**（`pnpm run test:bench`；必需的 Linux PR gate `node 24 / benchmarks`）：`packages/*/*/tests/` 下的 `*.bench.ts` 与 Client 面 `*.bench.client.ts` 文件按固定参数合成输入，绝不含录制材料，并在超出已记录的壁钟预算、堆限制或缩放比时失败（[规则与当前 gate](../.agents/notes/implemented/testing/2026-09-04-session-open-performance-gate.zh.md)）。
 - **快照**（`pnpm run test:snapshot`）：顶层场景数值最高的已录制 parent generation 同时提供用户输入和模型回放，并作为持久化结果的预期值。parent 文件名是 `session[.vN].jsonl`；child 角色使用 `session.<ordinal>[.vN].jsonl`；v0 省略 `.v0`，正版本必须使用小写 `.vN`，且每个文件名必须与其 header 一致。进程级场景都通过 `dsh` 启动：headless 负责一次性行为，SDK 负责持久控制，ACP 负责自动化协议行为，Web 在同一 Session 旁保留浏览器与 ARIA 证据。`snapshot.yml` 声明 profile、组合与请求头类别、录制策略、例外回放或输入元数据以及 workspace 事实。带类型的 token 保留父子身份关系；只有请求头 pin 拥有 prompt/schema sidecar。变更 workspace 的场景会独立比较完整的 `workspace.expected/` 目录，record 与 refresh 绝不改写该目录。当模型 transcript（文本记录）变化时使用 `test:snapshot:record`，回放输入仍有效时使用 `test:snapshot:refresh`；请审查所有结果差异。
 - **Web 浏览器快照**（`pnpm run test:web`；必需的 Linux PR（Pull Request）门禁）：Chromium 比较 `snapshots/web/` 下由会话驱动的输出，以及 `apps/web/tests/expected/` 下仅含 UI 的输出。CI 强制只读的 `DSH_SNAPSHOT=replay`，绝不写入预期输出；record/refresh 留在本地，每处 diff 都须评审（[web e2e 车道](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.zh.md)、[CI 门禁决策](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.zh.md)）。`test:web` 会先构建以交付插件 CSS。
 
-Session fixture 保留 header 与 payload，但省略正文 seq/time envelope；replay 会合成这些 envelope。Replay、record 与 refresh 会选择每个 parent/child 角色的最高 generation。当前 v2 使用 `.v2`、每个事件一行，并嵌入紧凑 Assistant stream；保留的 v0（无后缀）与 v1（`.v1`）可以为迁移覆盖保留规范 packed row。[迁移器](../scripts/migrate-packed-session-fixtures.ts)会改写更旧的历史布局。

Subject: [PATCH 30/70] test(perf): size the migration budget for the CI runner

The migrating first open of the synthetic log costs about 1 s on the
reference machine under the 128 MB heap limit and about twice that on the
CI runner, so 3,000 ms keeps headroom while staying far below the ~5 s
(~10 s on CI) of the repeated-snapshot implementation.

Subject: [PATCH 31/70] test(perf): allow the joined-text share in the fold
 scaling bound

A records-proportional fold still joins 20x more text in the large window,
which measured about 2.5x the small fold; the per-delta replay measured
about 11x. A 5x bound separates the two on a noisy runner.

Subject: [PATCH 32/70] test(perf): double the CI cost in the migration budget

The migrating first open measured 1,963 ms on the CI runner under the
128 MB heap limit; 4,000 ms keeps a 2x margin while the repeated-snapshot
implementation still fails by heap exhaustion and would need ~10 s.

 ## Problem
 
-The Session format v2 rollout changed two paths whose cost scales with model output: the JSONL backend migrates and publishes a released-v0 log on its first `open()`, and the Client folds each settled reply's embedded compact stream. Neither path had an executed performance check, so a first open that grew from about 35 ms to about 5 s on a 127,400-event synthetic log (and from about 0.3 s to 26 s on a 575,000-chunk real log, with peak RSS of 2.7 GB and heap exhaustion under a 512 MB limit) and a Client fold that grew linearly with streamed deltas instead of compact records both reached master unnoticed. Unit tests use small logs, the coverage gate measures lines, and the existing `test:web:perf` inventory is a manual diagnostic outside CI.

+
+Measuring only `SessionPersistence.open()` does not stably describe the result for which a user or Host waits. Work can move among `open()`, `SessionHandle.read()`, Session restoration, and projection, while the first history page and cold Agent resume add separate orchestration above those operations. A single `heapUsed` sample without prior GC also cannot distinguish data still retained by the Session from reclaimable migration temporaries.
 
 ## Decision
 
-Linux pull requests run a required `node 24 / benchmarks` job that executes `pnpm run check:ci:bench` → `pnpm run test:bench` → `vitest.bench.config.ts`, which collects `packages/*/*/tests/**/*.bench.ts` and `*.bench.client.ts` and runs one file at a time. The job runs the benchmark lane alone, on the same runner selector and failover switch as the other required Linux workers, and joins the `all checks passed` verdict.
+Linux pull requests run a required `node 24 / benchmarks` job that executes `pnpm run check:ci:bench` → `pnpm run test:bench` → `vitest.bench.config.ts`. The job runs the benchmark lane alone; Vitest runs one file at a time and only prepares input, starts measurement children, aggregates results, and enforces budgets.
 
-Every benchmark synthesizes its input in-process from fixed parameters: numbered prompts, counter tokens, fixed timestamps. Recorded Sessions are never used because they carry user content, differ between machines, and drift as fixtures are re-recorded. Each benchmark documents its budget beside the constant that enforces it, and budgets follow three rules: a wall-clock budget sits a small multiple above the intended cost and well below the regression it guards; a memory budget runs the measured path in a child Node process under a fixed `--max-old-space-size`, so an allocation regression fails as an out-of-memory exit regardless of the runner's physical memory; and a scaling assertion compares two sizes of the same workload so a complexity regression fails on any host speed.
+Required performance gates live under top-level `benchmarks/`, grouped by measured user path rather than package ownership. Host files use `*.bench.ts`, Client-face files use `*.bench.client.ts`, and scenario-specific workers and fixtures stay beside their benchmark without a benchmark suffix. Package-local `.perf.ts` files remain non-gating diagnostics; `scripts/` owns orchestration rather than benchmark cases.
 
-The first two gates cover the two regressed paths:
+The Session benchmarks synthesize a released-v0 input from fixed parameters: 200 turns with 500 text deltas and 125 reasoning deltas per turn, for 127,400 logical events. The input uses Zstandard with fixed logical-row grouping and frame partitioning, so every run processes the same events, bytes, and frame distribution. Setup writes the input into a private temporary directory for each sample before timing starts; benchmarks never use recorded Sessions.
 
-| Benchmark | Workload | Gates |
+Every Session endpoint runs at two user-lifecycle points. `first-open` starts with only the released V0 generation and therefore includes migration and successor publication. Setup produces `post-upgrade-reopen` once through that same production migration outside measurement, then copies both the unchanged V0 predecessor and published V2 successor into each sample root. Reopen samples use a fresh process, so they measure an upgraded user's later disk open without migration or process-local caches.
+
+Each access-kind and endpoint sample runs in a fresh Node child process. Module imports, Host service initialization, and fixture preparation finish before measurement; the measured process performs no extra parse warm-up. Normal-heap mode runs five independent samples, reports every sample plus minimum, median, and maximum, and enforces access-specific fixed budgets against the median. Another child runs the same path under a fixed 128 MB old-space limit and checks only that it completes; extra GC caused by the constrained heap does not enter the normal timing baseline.
+
+The lane contains three independent Session-opening benchmarks and retains the Client-fold benchmark:
+
+| Benchmark | Measured path | Timing metrics |
 |---|---|---|
-| `packages/session/session-persistence-jsonl/tests/open-generation.bench.ts` | 200 turns × (500 text + 125 reasoning deltas) = 127,400 released-v0 events, about 2.8 MB, encoded through the frozen v0 codec with packed rows | migrating first `open()` ≤ 4,000 ms under a 128 MB heap; fresh-process open of the published current generation ≤ 500 ms; minimum of three attempts |
-| `packages/client/ui-chat/tests/conversation-fold.bench.client.ts` | 200 replies whose compact streams hold 2,000 text + 500 reasoning deltas each (500,000 deltas in 1,600 records), folded through every Chat Definition by the real `ConversationNodeAssembler` | large fold ≤ 150 ms; large fold ≤ 5× the fold of the same window with 100 deltas per reply |
+| Phase profile | Executes the real persistence open, handle read, Session restore, and projection for both first open and post-upgrade reopen | `openMs`, `readMs`, `sessionRestoreMs`, and `projectionMs` each have a fixed budget; encoding, writes, verification, and publication awaited by migration all belong to first-open `openMs` |
+| First history | Reads each access kind through the Host Session history controller until it produces the first paginated snapshot | Separate first-open and reopen end-to-end budgets; each includes source stat, reading, restoration, projection, pagination, and snapshot construction, while first open additionally includes migration; both exclude Gateway network transport, Client fold, and browser paint |
+| Agent resume | Calls `ctx.agents.resume()` for each access kind until Agent creation, setup, publication, and loop startup finish | Separate first-open and reopen end-to-end budgets; neither path runs after first-history or reuses that benchmark's cache |
+| Client fold | Folds small and large v2 history windows through the real `ConversationNodeAssembler` and every Chat Definition | The large window's absolute time and scaling relative to the small window each have a fixed budget |
 
-Measured on the reference machine at the commit that introduced the gate, the migration benchmark exhausted the 128 MB heap and the fold benchmark scaled 11× between the small and large windows, so both gates fail on the regressed code and pass once the paths do O(records) work.
+The phase profile invokes each layer's production entry point explicitly and does not copy any decode, migration, restore, or projection algorithm. First-history and Agent-resume each run their real higher-level entry point against fresh first-open and reopen roots, so component measurements do not stand in for end-to-end results and one scenario cannot warm another's process or Session cache. The sum of the four phases is diagnostic only; an outer clock independently measures each end-to-end result.
+
+Normal-heap mode performs a fixed pair of explicit garbage collections after Host initialization and before the cold Session is touched, then records starting memory. It stops operation timing before performing the same garbage-collection sequence while the scenario's intended long-lived objects remain explicitly reachable, then records ending memory. The Agent-resume endpoint retains the Agent, Session, complete events, and normal service caches; its `heapUsed` delta is the primary resident-Session memory budget. Every scenario also reports `external`, `arrayBuffers`, post-GC RSS, and `process.resourceUsage().maxRSS`; the 128 MB mode prevents transient allocation peaks from being hidden by endpoint collection. Explicit garbage-collection time is excluded from operation timing.
+
+The performance gate does not duplicate semantic assertions owned by functional tests; it requires only that the target call completes and reaches its measured endpoint. The Client-fold benchmark continues to use the real `ConversationNodeAssembler` and every Chat Definition, and requires both the large window's absolute time and its scaling relative to the small window to remain below fixed budgets.
+
+Budgets use repeated measurements of the final implementation on the target CI runner, with enough margin for runner noise while remaining below the known regression. Pre-stack commit `0d7ea53743e273930a31e9e2b6ca682f21dd4ca5` is the fixed calibration and review reference; CI does not check out or execute the historical repository. Budgets are reviewed source constants and have no environment-variable override.
+
+## Calibration evidence
+
+The comparison is orthogonal by user lifecycle, not by artifact representation. Both implementations receive the same fixed V0 bytes for first open. For reopen, each implementation reads the format it considers current in a fresh process: the pre-stack reference remains on V0, while the V2 implementation reads its published V2 successor. This intentionally compares the same user's later-open experience rather than two codecs over one data structure.
+
+Five-sample medians on the same Node 24 reference machine establish the positive and negative controls:
+
+| Access kind | Implementation | Four-phase total | First history | Agent resume | 128 MB old space |
+|---|---|---:|---:|---:|---|
+| First open | Pre-stack reference | 249.0 ms | 253.8 ms | 100.7 ms | Completes |
+| First open | Repeated-snapshot regression | 4,197.5 ms | 4,284.8 ms | 4,197.9 ms | Exhausts heap |
+| Post-upgrade reopen | Pre-stack reference | 251.1 ms | 253.8 ms | 100.7 ms | Completes |
+| Post-upgrade reopen | Repeated-snapshot regression | 49.2 ms | 50.4 ms | 43.8 ms | Completes |
+
+The pre-stack implementation keeps V0 as its current format, so first open does not change its on-disk representation; its native V0 first-history and Agent-resume measurements therefore apply to both lifecycle rows.
 
 ## Alternatives considered
 
-**Extend the manual `test:web:perf` inventory.** Rejected: it stays outside CI by design, measures a simplified fold rather than the registered Definitions, and asserts nothing.
+**Check out the historical commit and compare it on every CI run.** Rejected because a historical checkout requires a separate install, and old and current revisions can assign work to different API phases, adding runtime, dependency, and interface drift. A fixed workload with static budgets calibrated against positive and negative controls is easier to reproduce and review.
 
-**Time-only budgets.** Rejected: a single absolute budget either fails on slower runners or passes a regression on faster ones; the heap cap and the scaling ratio give host-independent verdicts, and the wall-clock budget remains as the timeout that the user-visible symptom is about.
+**Measure only first open from V0.** Rejected because migration is a one-time upgrade cost and cannot protect later opens of the settled current generation from regressions. The two access kinds need separate measurements and budgets.
 
-**Benchmark the real recorded corpus.** Rejected: corpus fixtures are small by policy, recorded material must not become a benchmark input, and their re-recording would silently move the baseline.
+**Measure only the four component phases.** Rejected because component measurements locate cost but omit source stat, orchestration, pagination, and snapshot construction, and cannot prove that the complete first-history path remains usable and fast enough.
 
-**Run the benchmarks inside an existing gate aggregate.** Rejected: aggregates run gates concurrently on one runner, so wall-clock measurements would inherit the neighbours' CPU load.
+**Measure only first-history or Agent-resume total time.** Rejected because an end-to-end number protects the result but cannot identify whether storage, reading, Session restoration, or projection regressed; four phase budgets retain actionable attribution.
+
+**Add fine-grained timing instrumentation inside production implementations.** Rejected because those probes would expand production APIs and couple the benchmark to implementation details. Tests use existing service and object boundaries; costs that those boundaries cannot attribute remain part of the end-to-end result.
+
+**Use only time budgets or only post-GC memory.** Rejected because time does not reveal memory regressions, while endpoint live memory cannot expose transient migration spikes. Normal-heap post-GC deltas and constrained-heap completion cover the two risks separately.
+
+**Benchmark the real recorded corpus.** Rejected because corpus fixtures stay small by policy, recorded material must not become benchmark input, and re-recording would silently move the workload.
+
+**Run benchmarks inside an existing gate aggregate.** Rejected because aggregate gates run concurrently on one runner, so wall-clock measurements inherit neighbouring CPU load.
+
+**Keep each cross-package gate under one participating product package.** Rejected because Session opening spans persistence, migration, projection, Host history, and Agent resume; choosing one participant creates misleading ownership and benchmark-only package dependencies. The repository-level tree owns the integrated user path, while package-local diagnostics remain with their implementation.
+
+**Put benchmark cases under `scripts/`.** Rejected because scripts own commands, generators, and orchestration, while a benchmark case owns typed test files, workers, fixtures, budgets, and lifecycle cleanup. A future reporting or calibration command may consume `benchmarks/` without moving the cases there.
 
 ## Consequences
 
-Every pull request pays one more required Linux job of a few minutes, dominated by install time rather than the benchmarks themselves. A change that makes first open or the Client fold slower than its budget, heavier than its heap limit, or proportional to streamed deltas fails in the PR that introduces it, with the measured numbers printed in the job log. A budget change is a reviewed edit of the constant and its rationale comment, never an environment override, and a new benchmark must state which owner-visible path and which regression class it guards. The gate does not measure browser rendering, network transfer, or real recorded Sessions; those remain covered by the manual `test:web:perf` inventory and by review.
+Every pull request pays for one required Linux job; its Session portion runs several short-lived child processes in exchange for cold caches, isolated V8 heaps, explicit GC state, and attributable failures. The repository-level benchmark tree accepts deliberate cross-package test dependencies without changing product package manifests. The fixed Zstandard workload covers both event volume and frame topology; first-open measurements protect the one-time upgrade experience, reopen measurements prevent regressions in later opens, phase budgets locate cost, first-history budgets protect user-visible waiting, Agent-resume budgets and post-GC deltas protect complete cold activation and resident memory, and the 128 MB mode protects the transient allocation ceiling.
+
+The gate does not measure network transfer, browser rendering, or recorded Sessions, and it is not a continuous performance-trend system. A Node or runner change requires resampling the same workload and reviewing the budgets; a business-implementation change must not relax a budget without new positive and negative control data.

 ## 问题

 ## 决定

-每个基准都在进程内按固定参数合成输入：编号的 prompt、计数 token、固定时间戳。绝不使用录制的 Session，因为它们携带用户内容、在不同机器上不同，并随 fixture 重新录制而漂移。每个基准在强制执行预算的常量旁记录其预算，预算遵循三条规则：壁钟预算取目标成本的小倍数并远低于所防护的回归；内存预算把被测路径放在固定 `--max-old-space-size` 的子 Node 进程中运行，使分配回归无论 runner 物理内存多大都以 out-of-memory 退出失败；缩放断言比较同一负载的两个规模，使复杂度回归在任何主机速度下都失败。
+必需性能 gate 位于顶层 `benchmarks/`，按被测用户路径而非 package 归属组织。Host 文件使用 `*.bench.ts`，Client 面文件使用 `*.bench.client.ts`，场景专属 worker 与 fixture 留在对应 benchmark 旁且不带 benchmark 后缀。包内 `.perf.ts` 文件仍是非门禁诊断；`scripts/` 负责编排而不承载 benchmark case。
 
-前两个 gate 覆盖两条回归路径：
+Session benchmark 使用固定参数合成 released-v0 输入：200 轮，每轮 500 个 text delta 与 125 个 reasoning delta，共 127,400 个逻辑事件。输入使用 Zstandard，并固定 logical rows 的分组与 frame 拆分，使每次运行处理相同的事件、字节与 frame 分布。输入在计时前写入每个样本独占的临时目录；benchmark 不使用录制的 Session。
 
-| 基准 | 负载 | Gate |
+每个 Session endpoint 都针对用户生命周期中的两个时点运行。`first-open` 最初只有 released V0 generation，因此包含 migration 与后继 generation 发布。测试准备阶段在计时外通过同一套生产 migration 生成一次 `post-upgrade-reopen`，再把未改动的 V0 前代和已发布的 V2 后继一起复制到每个样本目录。Reopen 样本使用全新进程，因此测量用户升级完成后的磁盘再次打开，不包含 migration 或进程内 cache。
+
+每个 access kind 与 endpoint 的样本都在全新 Node 子进程中运行。模块加载、Host 服务初始化和 fixture 准备在测量开始前完成；测量进程不执行额外的预热解析。正常堆模式运行五个独立样本，报告全部样本及最小值、中位数和最大值，并以中位数执行各访问状态独立的固定预算。另一个子进程使用固定 128 MB old-space 上限运行同一路径，只判断能否完成；低堆限制引起的额外 GC 不进入正常时间基线。
+
+该 lane 包含三个独立的 Session 打开 benchmark，并保留 Client fold benchmark：
+
+| Benchmark | 被测路径 | 时间指标 |
 |---|---|---|
-| `packages/session/session-persistence-jsonl/tests/open-generation.bench.ts` | 200 轮 ×（500 text + 125 reasoning delta）= 127,400 个 released-v0 事件，约 2.8 MB，经冻结 v0 codec 以 packed row 编码 | 迁移的首次 `open()` 在 128 MB 堆下 ≤ 4,000 ms；新进程打开已发布 current generation ≤ 500 ms；三次尝试取最小值 |
-| `packages/client/ui-chat/tests/conversation-fold.bench.client.ts` | 200 个回复，每个紧凑 stream 含 2,000 text + 500 reasoning delta（1,600 条记录中 500,000 个 delta），由真实 `ConversationNodeAssembler` 经全部 Chat Definition fold | 大窗口 fold ≤ 150 ms；大窗口 fold ≤ 每回复 100 delta 的同一窗口的 5 倍 |
+| 阶段剖面 | 分别为 first open 与 post-upgrade reopen 执行真实 persistence open、handle read、Session restore 与 projection | `openMs`、`readMs`、`sessionRestoreMs`、`projectionMs` 各自使用固定预算；migration 所等待的编码、写入、verify 与 publish 全部归入 first-open `openMs` |
+| 首屏历史 | 两种 access kind 分别经 Host Session history controller 读取到首个分页 snapshot | First open 与 reopen 各有一个端到端预算；均包含 source stat、读取、Session restore、projection、分页与 snapshot 构造，first open 还包含 migration；两者都不包含 Gateway 网络传输、Client fold 或浏览器 paint |
+| Agent resume | 对两种 access kind 分别调用 `ctx.agents.resume()`，直到 Agent 创建、setup、发布与 loop 启动完成 | First open 与 reopen 各有一个端到端预算；两条路径都不与首屏历史串行，也不依赖它留下的 cache |
+| Client fold | 大小两个 v2 history window 经真实 `ConversationNodeAssembler` 与全部 Chat Definition fold | 大窗口的绝对时间与相对小窗口的缩放比各自使用固定预算 |
 
-在引入该 gate 的提交上于参考机器测得：迁移基准耗尽 128 MB 堆，fold 基准在小窗口与大窗口之间缩放 11 倍，因此两个 gate 都在回归代码上失败，并在两条路径改为 O(records) 工作后通过。
+阶段剖面显式调用各层正式入口，不复制 decode、migration、restore 或 projection 算法。首屏历史和 Agent resume 分别以新的 first-open 与 reopen 根目录运行真实上层入口，因此组件数据不冒充端到端结果，一个场景也不会给另一个场景预热进程或 Session cache。四阶段之和仅用于解释成本；首屏与 Agent resume 的端到端时间各自由外层时钟直接测量。
+
+正常堆模式在 Host 初始化完成且 Session 尚未访问时执行固定的两轮显式 GC，记录起点内存；操作计时结束后，在该场景要求的长期对象仍明确可达时再次执行同样的 GC，再记录终点内存。Agent resume 场景在终点保留 Agent、Session、完整 events 与正常服务 cache，它的 `heapUsed` 增量是常驻 Session 内存预算的主指标。每个场景同时报告 `external`、`arrayBuffers`、GC 后 RSS 和 `process.resourceUsage().maxRSS`；128 MB 模式继续防止瞬时分配峰值被终点 GC 隐藏。显式 GC 时间不计入操作时间。
+
+性能 gate 不重复功能测试的内容断言，只要求目标调用完成并到达对应的可观察终点。Client fold benchmark 继续使用真实 `ConversationNodeAssembler` 与全部 Chat Definition，要求大窗口的绝对时间和相对小窗口的缩放比均低于固定预算。
+
+预算以最终实现于目标 CI runner 上的多次样本为基线，并保留足以吸收 runner 波动、但仍能区分已知退化的余量。栈前参考提交固定为 `0d7ea53743e273930a31e9e2b6ca682f21dd4ca5`，只用于校准和评审预算；CI 不 checkout 或执行历史仓库。预算是源码中的受评审常量，不由环境变量覆盖。
+
+## 校准证据
+
+比较按用户生命周期正交，而不是按产物表示正交。两种实现的 first open 都接收完全相同的固定 V0 字节。Reopen 时，每种实现都在全新进程中读取自己认定的当前格式：栈前参考版本仍读取 V0，V2 实现则读取它已发布的 V2 后继。这里有意比较同一用户后续打开的体验，而不是让两个 codec 处理同一种数据结构。
+
+同一台 Node 24 参考机器上的五次样本中位数构成正反例：
+
+| Access kind | 实现 | 四阶段总时间 | 首屏历史 | Agent resume | 128 MB old space |
+|---|---|---:|---:|---:|---|
+| First open | 栈前参考版本 | 249.0 ms | 253.8 ms | 100.7 ms | 完成 |
+| First open | 重复 snapshot 退化实现 | 4,197.5 ms | 4,284.8 ms | 4,197.9 ms | 堆耗尽 |
+| Post-upgrade reopen | 栈前参考版本 | 251.1 ms | 253.8 ms | 100.7 ms | 完成 |
+| Post-upgrade reopen | 重复 snapshot 退化实现 | 49.2 ms | 50.4 ms | 43.8 ms | 完成 |
+
+栈前实现以 V0 作为当前格式，因此 first open 不改变磁盘表示；它的原生 V0 首屏历史与 Agent resume 测量同时适用于两个生命周期行。
 
 ## 考虑过的替代方案

+**每次 CI checkout 历史提交并做相对比较。** 拒绝：历史 checkout 需要独立安装，旧版与当前版还可能把工作放在不同 API 阶段，增加时间、依赖和接口漂移。固定 workload 与经正反例校准的静态预算更容易复现和评审。
 
-**只用时间预算。** 拒绝：单一绝对预算要么在较慢的 runner 上失败，要么在较快的 runner 上放过回归；堆上限与缩放比给出与主机无关的判定，壁钟预算则作为用户可见症状所对应的超时保留。
+**只测从 V0 first open。** 拒绝：migration 是一次性升级成本，不能防止进入稳定当前 generation 后的后续打开发生退化。两种 access kind 需要独立的测量与预算。
 
-**用真实录制语料做基准。** 拒绝：语料 fixture 按策略保持小体量，录制材料不得成为基准输入，且其重新录制会静默移动基线。
+**只测四个组件阶段。** 拒绝：组件测量便于定位，但会遗漏 source stat、编排、分页和 snapshot 构造，也不能证明首屏路径整体仍然可用且足够快。
 
-**把基准放进现有 gate 聚合中运行。** 拒绝：聚合在一个 runner 上并发运行各 gate，壁钟测量会继承邻居的 CPU 负载。
+**只测首屏或 Agent resume 总时间。** 拒绝：端到端数字能保护结果，却不能指出退化来自存储、读取、Session restore 还是 projection；四阶段预算保留可操作的归因。
+
+**在生产实现内部添加细粒度计时桩。** 拒绝：这些桩会扩大生产接口并让 benchmark 与实现细节耦合。测试只使用既有服务和对象边界；无法由这些边界解释的成本保留在端到端结果中。
+
+**只用时间预算或只看 GC 后内存。** 拒绝：时间无法发现内存退化，终点存活内存也看不到迁移期间的瞬时爆发。正常堆的 GC 后增量与受限堆的完成性分别覆盖两类风险。
+
+**用真实录制语料做 benchmark。** 拒绝：语料 fixture 按策略保持小体量，录制材料不得成为 benchmark 输入，且其重新录制会静默移动 workload。
+
+**把 benchmark 放进现有 gate 聚合中运行。** 拒绝：聚合在一个 runner 上并发运行各 gate，壁钟测量会继承邻居的 CPU 负载。
+
+**把每个跨包 gate 放在一个参与的产品 package 下。** 拒绝：Session 打开跨越 persistence、migration、projection、Host history 与 Agent resume；任选一个参与方都会形成误导性的归属和仅为 benchmark 增加的 package 依赖。仓库级目录拥有集成用户路径，包内诊断仍留在对应实现旁。
+
+**把 benchmark case 放在 `scripts/` 下。** 拒绝：scripts 拥有命令、生成器与编排，而 benchmark case 拥有带类型的测试文件、worker、fixture、预算和生命周期清理。未来的报告或校准命令可以消费 `benchmarks/`，不需要把 case 移入其中。
 
 ## 后果
 
-每个 pull request 多付出一个几分钟的必需 Linux job，其时间主要花在安装而不是基准本身。让首次打开或 Client fold 慢于预算、重于堆限制或与流式 delta 数成正比的改动，会在引入它的 PR 中失败，并把测得的数字打印在 job 日志里。预算变更是对常量及其理由注释的受评审编辑，绝不是环境变量覆盖；新增基准必须说明它防护哪条 owner 可见路径和哪类回归。该 gate 不测量浏览器渲染、网络传输或真实录制的 Session；这些仍由手动 `test:web:perf` 清单和评审覆盖。
+每个 pull request 多付出一个必需 Linux job；该 job 的 Session 部分运行多个短生命周期子进程，以换取冷 cache、独立 V8 heap、明确 GC 状态和可归因的失败。仓库级 benchmark 目录接受有意的跨包测试依赖，而不修改产品 package manifest。固定 Zstandard workload 同时覆盖事件规模与 frame 拓扑；first-open 测量保护一次性升级体验，reopen 测量防止后续打开退化，四阶段预算定位成本归属，首屏预算保护用户可见等待，Agent resume 预算与 GC 后增量保护完整冷恢复及常驻内存，128 MB 模式保护瞬时分配上限。
+
+该 gate 不测量网络传输、浏览器渲染或真实录制 Session，也不是持续性能趋势系统。Node 或 runner 变化需要用同一 workload 重新采样并评审预算；修改业务实现时不得顺带放宽预算而不提供新的正反例数据。

+# AGENTS.md — Performance Benchmarks
+
+This tree owns required, repository-level performance gates whose measured user path crosses package ownership. Package-local diagnostics remain beside their owners and use the `.perf.ts` suffix instead of joining `test:bench`.
+
+- Organize benchmarks by measured user path, one directory per path. Do not mirror the package tree.
+- Host cases use `*.bench.ts`; Client-face cases use `*.bench.client.ts`. Worker, fixture, and support modules do not carry a benchmark suffix.
+- Synthesize fixed inputs from reviewed constants. Never use recorded Sessions, user material, ambient repositories, or network services.
+- Run process-level wall-clock and retained-memory samples in fresh children with private `mkdtemp` roots. Pure synchronous folds create a fresh object graph per sample and must not mutate process-global state. Bound every child, await exit, and remove owned roots after failure as well as success.
+- Report enough raw and aggregate measurements to explain each verdict, including whether a budget uses a median, minimum, absolute value, or ratio. Enforce reviewed source constants; environment variables must not override performance budgets.
+- Keep scenario-specific support beside its benchmark. Move a helper into `benchmarks/support/` only after at least two benchmark directories require the same behavior.
+- Exercise production entry points. Do not copy product algorithms, add production exports solely for measurement, or turn benchmark completion into duplicate semantic assertions.
+- Record the workload, timing boundary, memory endpoint, calibration reference, alternatives, and known exclusions in the owning Agent Note.

@@ -10,7 +10,7 @@ How this repo tests, tier by tier, and the rules that keep a green suite meaning
 - **Coverage gate** (`pnpm run test:coverage`): the gating run, per-file 100% on `packages/*/*/src`. An uncovered line is often dead code the gate flags for deletion, not a missing test to bolt on. Line coverage is necessary, never sufficient — it proves lines ran, not that the feature works as shipped. Per-file 100% on `packages/shell/pwsh-local/src` needs a real `pwsh`: without one its executor suites self-skip and `vitest.config.ts` exempts the file so pwsh-less hosts stay green, while CI runners ship pwsh and enforce the full bar.
 - **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
 - **Owner-local expected output** (`pnpm run test:expected`): keyless assembled CLI/process expectations without a recorded-session round trip. Drivers use `*.expected.e2e.ts` beside `tests/expected/`; CI runs built exports. Package/script expectations use `test`, while browser expectations use `test:web`.
-- **Performance benchmarks** (`pnpm run test:bench`; required Linux PR gate `node 24 / benchmarks`): `*.bench.ts` and Client-face `*.bench.client.ts` files under `packages/*/*/tests/` synthesize input from fixed parameters, never recorded material, and fail on a documented wall-clock budget, heap limit, or scaling ratio ([rules and current gates](../.agents/notes/implemented/testing/2026-09-04-session-open-performance-gate.md)).
+- **Performance benchmarks** (`pnpm run test:bench`; required Linux PR gate `node 24 / benchmarks`): top-level `benchmarks/` holds `*.bench.ts` and Client-face `*.bench.client.ts` gates grouped by user path. They synthesize fixed inputs, never recordings, and enforce documented wall-clock, heap, or scaling budgets; package-local `.perf.ts` remains diagnostic ([rules](../.agents/notes/implemented/testing/2026-09-04-session-open-performance-gate.md)).
 - **Snapshot** (`pnpm run test:snapshot`): a top-level scenario's highest recorded parent generation supplies user input and model replay, then serves as the expected persisted result. Parent filenames are `session[.vN].jsonl`; child roles are `session.<ordinal>[.vN].jsonl`; v0 omits `.v0`, positive versions require lowercase `.vN`, and each filename must agree with its header. Process scenarios start through `dsh`: headless owns one-shot behavior, the SDK owns persistent control, ACP owns automation-protocol behavior, and Web retains browser/ARIA evidence beside the same Session. `snapshot.yml` declares the profile, composition/header class, recording policy, exceptional replay or input metadata, and workspace facts. Typed tokens preserve parent/child identity relationships; only header pins own prompt/schema sidecars. A mutating scenario independently compares the complete `workspace.expected/` tree, which record and refresh never rewrite. Use `test:snapshot:record` when a model transcript changes and `test:snapshot:refresh` when replay input remains valid; review every resulting diff.
 - **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares session-driven output under `snapshots/web/` and UI-only output under `apps/web/tests/expected/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` builds first for plugin CSS.

+The Session benchmarks synthesize a released-v0 input from fixed parameters: 200 turns with 500 text deltas and 125 reasoning deltas per turn, for 127,400 logical events. The input uses Zstandard with fixed logical-row grouping and frame partitioning, so every run processes the same events, bytes, and frame distribution. The fixture constructs the immutable released-v0 physical rows directly instead of depending on a current-runtime historical encoder; compression and every measured read or migration entry point still use production code. Setup writes the input into a private temporary directory for each sample before timing starts; benchmarks never use recorded Sessions.
 
 Every Session endpoint runs at two user-lifecycle points. `first-open` starts with only the released V0 generation and therefore includes migration and successor publication. Setup produces `post-upgrade-reopen` once through that same production migration outside measurement, then copies both the unchanged V0 predecessor and published V2 successor into each sample root. Reopen samples use a fresh process, so they measure an upgraded user's later disk open without migration or process-local caches.

+Session benchmark 使用固定参数合成 released-v0 输入：200 轮，每轮 500 个 text delta 与 125 个 reasoning delta，共 127,400 个逻辑事件。输入使用 Zstandard，并固定 logical rows 的分组与 frame 拆分，使每次运行处理相同的事件、字节与 frame 分布。fixture 直接构造不可变的 released-v0 physical rows，不依赖当前 runtime 的历史 encoder；压缩以及所有被测读取和 migration 入口仍使用生产代码。输入在计时前写入每个样本独占的临时目录；benchmark 不使用录制的 Session。
 
 每个 Session endpoint 都针对用户生命周期中的两个时点运行。`first-open` 最初只有 released V0 generation，因此包含 migration 与后继 generation 发布。测试准备阶段在计时外通过同一套生产 migration 生成一次 `post-upgrade-reopen`，再把未改动的 V0 前代和已发布的 V2 后继一起复制到每个样本目录。Reopen 样本使用全新进程，因此测量用户升级完成后的磁盘再次打开，不包含 migration 或进程内 cache。

+Linux pull requests run a required `node 24 / benchmarks` job that executes `pnpm run check:ci:bench` → `pnpm run test:bench`. The command first builds workspace libraries and dedicated benchmark workers, then invokes `vitest.bench.config.ts`. The job runs the benchmark lane alone; Vitest runs one file at a time and only prepares input, starts measurement children, aggregates results, and enforces budgets. Every timed CPU path executes compiled JavaScript under plain Node with `NODE_OPTIONS` removed and no TypeScript loader; bare workspace imports therefore resolve through package exports to built `lib/` entries.
 
 Required performance gates live under top-level `benchmarks/`, grouped by measured user path rather than package ownership. Host files use `*.bench.ts`, Client-face files use `*.bench.client.ts`, and scenario-specific workers and fixtures stay beside their benchmark without a benchmark suffix. Package-local `.perf.ts` files remain non-gating diagnostics; `scripts/` owns orchestration rather than benchmark cases.

 Every Session endpoint runs at two user-lifecycle points. `first-open` starts with only the released V0 generation and therefore includes migration and successor publication. Setup produces `post-upgrade-reopen` once through that same production migration outside measurement, then copies both the unchanged V0 predecessor and published V2 successor into each sample root. Reopen samples use a fresh process, so they measure an upgraded user's later disk open without migration or process-local caches.

 The performance gate does not duplicate semantic assertions owned by functional tests; it requires only that the target call completes and reaches its measured endpoint.

 **Add fine-grained timing instrumentation inside production implementations.** Rejected because those probes would expand production APIs and couple the benchmark to implementation details. Tests use existing service and object boundaries; costs that those boundaries cannot attribute remain part of the end-to-end result.
 
+**Run measured workers from TypeScript source.** Rejected because a source loader changes module resolution and startup behavior, and causes nested workers to select source-only bootstrap paths. Vitest remains an unmeasured orchestrator; every timed worker executes the build output exactly as plain Node consumers do.

 **Use only time budgets or only post-GC memory.** Rejected because time does not reveal memory regressions, while endpoint live memory cannot expose transient migration spikes. Normal-heap post-GC deltas and constrained-heap completion cover the two risks separately.
 
 **Benchmark the real recorded corpus.** Rejected because corpus fixtures stay small by policy, recorded material must not become benchmark input, and re-recording would silently move the workload.

 - Organize benchmarks by measured user path, one directory per path. Do not mirror the package tree.
 - Host cases use `*.bench.ts`; Client-face cases use `*.bench.client.ts`. Worker, fixture, and support modules do not carry a benchmark suffix.
+- `test:bench` builds workspace libraries and `.dsh-build/benchmarks/` workers before Vitest orchestration. Timed CPU work runs in those workers under plain Node, without a TypeScript loader; runtime package imports must resolve to built `lib/` entries.
 - Synthesize fixed inputs from reviewed constants. Never use recorded Sessions, user material, ambient repositories, or network services.
 - Run process-level wall-clock and retained-memory samples in fresh children with private `mkdtemp` roots. Pure synchronous folds create a fresh object graph per sample and must not mutate process-global state. Bound every child, await exit, and remove owned roots after failure as well as success.
 - Report enough raw and aggregate measurements to explain each verdict, including whether a budget uses a median, minimum, absolute value, or ratio. Enforce reviewed source constants; environment variables must not override performance budgets.
 - Keep scenario-specific support beside its benchmark. Move a helper into `benchmarks/support/` only after at least two benchmark directories require the same behavior.
 - Exercise production entry points. Do not copy product algorithms, add production exports solely for measurement, or turn benchmark completion into duplicate semantic assertions.
+- A compiled worker may bundle a private integration adapter when no public Node export exposes the measured user path. Keep package imports external so product services resolve through their built package exports.
 - Record the workload, timing boundary, memory endpoint, calibration reference, alternatives, and known exclusions in the owning Agent Note.

@@ -10,7 +10,7 @@ How this repo tests, tier by tier, and the rules that keep a green suite meaning
 - **Coverage gate** (`pnpm run test:coverage`): the gating run, per-file 100% on `packages/*/*/src`. An uncovered line is often dead code the gate flags for deletion, not a missing test to bolt on. Line coverage is necessary, never sufficient — it proves lines ran, not that the feature works as shipped. Per-file 100% on `packages/shell/pwsh-local/src` needs a real `pwsh`: without one its executor suites self-skip and `vitest.config.ts` exempts the file so pwsh-less hosts stay green, while CI runners ship pwsh and enforce the full bar.
 - **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
 - **Owner-local expected output** (`pnpm run test:expected`): keyless assembled CLI/process expectations without a recorded-session round trip. Drivers use `*.expected.e2e.ts` beside `tests/expected/`; CI runs built exports. Package/script expectations use `test`, while browser expectations use `test:web`.
-- **Performance benchmarks** (`pnpm run test:bench`; required Linux PR gate `node 24 / benchmarks`): top-level `benchmarks/` holds `*.bench.ts` and Client-face `*.bench.client.ts` gates grouped by user path. They synthesize fixed inputs, never recordings, and enforce documented wall-clock, heap, or scaling budgets; package-local `.perf.ts` remains diagnostic ([rules](../.agents/notes/implemented/testing/2026-09-04-session-open-performance-gate.md)).
+- **Performance benchmarks** (`pnpm run test:bench`; required Linux PR gate `node 24 / benchmarks`): `benchmarks/` groups user-path gates. It builds libraries and workers; timed code runs under plain Node, never TSX. Synthetic inputs enforce time, heap, and scaling budgets; package-local `.perf.ts` stays diagnostic ([rules](../.agents/notes/implemented/testing/2026-09-04-session-open-performance-gate.md)).
 - **Snapshot** (`pnpm run test:snapshot`): a top-level scenario's highest recorded parent generation supplies user input and model replay, then serves as the expected persisted result. Parent filenames are `session[.vN].jsonl`; child roles are `session.<ordinal>[.vN].jsonl`; v0 omits `.v0`, positive versions require lowercase `.vN`, and each filename must agree with its header. Process scenarios start through `dsh`: headless owns one-shot behavior, the SDK owns persistent control, ACP owns automation-protocol behavior, and Web retains browser/ARIA evidence beside the same Session. `snapshot.yml` declares the profile, composition/header class, recording policy, exceptional replay or input metadata, and workspace facts. Typed tokens preserve parent/child identity relationships; only header pins own prompt/schema sidecars. A mutating scenario independently compares the complete `workspace.expected/` tree, which record and refresh never rewrite. Use `test:snapshot:record` when a model transcript changes and `test:snapshot:refresh` when replay input remains valid; review every resulting diff.
 - **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares session-driven output under `snapshots/web/` and UI-only output under `apps/web/tests/expected/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` builds first for plugin CSS.

 The performance gate does not duplicate semantic assertions owned by functional tests; it requires only that the target call completes and reaches its measured endpoint. The Client-fold benchmark continues to use the real `ConversationNodeAssembler` and every Chat Definition, and requires both the large window's absolute time and its scaling relative to the small window to remain below fixed budgets.
 
-Budgets are layered. The first-open `open` limit, constrained-heap completion checks, and Client-fold scaling bound reject the known regressions; first-history and Agent-resume limits are broader orchestration ceilings that catch additional overhead without duplicating those component verdicts. Repeated measurements on the target CI runner leave margin for runner noise. Pre-stack commit `0d7ea53743e273930a31e9e2b6ca682f21dd4ca5` is the fixed calibration and review reference; CI does not check out or execute the historical repository. Budgets are reviewed source constants and have no environment-variable override.
+Budgets are calibrated per measured endpoint. Two repeated Node 24.19 x64 CI runs differ by at most 5.2% in their medians; their CPU-heavy wall times are 1.95–2.06× the Node 24.18 arm64 reference run. Source constants record expected reference-machine durations; `ciTimeBudget()` multiplies them by the measured 2× CI time scale and 1.25× variance headroom. The retained-heap and Client-fold scaling budgets use only the 1.25× headroom because neither is a wall-clock duration. The 128 MB completion check remains an independent transient-allocation limit. The resulting first-open time limits, constrained-heap checks, and Client-fold limits all reject the known regressions.

 ## Alternatives considered
 
 **Check out the historical commit and compare it on every CI run.** Rejected because a historical checkout requires a separate install, and old and current revisions can assign work to different API phases, adding runtime, dependency, and interface drift. A fixed workload with static budgets calibrated against positive and negative controls is easier to reproduce and review.

 ## Decision
 
-Linux pull requests run a required `node 24 / benchmarks` job that executes `pnpm run check:ci:bench` → `pnpm run test:bench`. The command first builds workspace libraries and dedicated benchmark workers, then invokes `vitest.bench.config.ts`. The job runs the benchmark lane alone; Vitest runs one file at a time and only prepares input, starts measurement children, aggregates results, and enforces budgets. Every timed CPU path executes compiled JavaScript under plain Node with `NODE_OPTIONS` removed and no TypeScript loader; bare workspace imports therefore resolve through package exports to built `lib/` entries.

 Required performance gates live under top-level `benchmarks/`, grouped by measured user path rather than package ownership. Host files use `*.bench.ts`, Client-face files use `*.bench.client.ts`, and scenario-specific workers and fixtures stay beside their benchmark without a benchmark suffix. Package-local `.perf.ts` files remain non-gating diagnostics; `scripts/` owns orchestration rather than benchmark cases.

 - **Snapshot** (`pnpm run test:snapshot`): a top-level scenario's highest recorded parent generation supplies user input and model replay, then serves as the expected persisted result. Parent filenames are `session[.vN].jsonl`; child roles are `session.<ordinal>[.vN].jsonl`; v0 omits `.v0`, positive versions require lowercase `.vN`, and each filename must agree with its header. Process scenarios start through `dsh`: headless owns one-shot behavior, the SDK owns persistent control, ACP owns automation-protocol behavior, and Web retains browser/ARIA evidence beside the same Session. `snapshot.yml` declares the profile, composition/header class, recording policy, exceptional replay or input metadata, and workspace facts. Typed tokens preserve parent/child identity relationships; only header pins own prompt/schema sidecars. A mutating scenario independently compares the complete `workspace.expected/` tree, which record and refresh never rewrite. Use `test:snapshot:record` when a model transcript changes and `test:snapshot:refresh` when replay input remains valid; review every resulting diff.
 - **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares session-driven output under `snapshots/web/` and UI-only output under `apps/web/tests/expected/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` builds first for plugin CSS.
 
-Session fixtures retain headers and payloads but omit body sequence/time envelopes; replay synthesizes them and, like record and refresh, selects each role's highest generation. Retained v0 and v1 generations may keep packed rows for migration coverage; [the migrator](../scripts/migrate-packed-session-fixtures.ts) rewrites older layouts.
+Session fixtures retain headers and payloads but omit body sequence/time envelopes; replay synthesizes them. Replay, record, and refresh select each parent/child role's highest generation. Current v2 uses `.v2`, one row per event, and embedded compact Assistant streams; retained v0 (suffixless) and v1 (`.v1`) may keep canonical packed rows for migration coverage. [The migrator](../scripts/migrate-packed-session-fixtures.ts) rewrites older historical layouts.
 
 ## How specs execute
 
-Forked workers run several spec files at once, the coverage gate splits into concurrent partitions beside the other gates in its job, and the self-hosted runners share one host and one volume. Only the process is isolated: ports, predictable paths, external namespaces, and inherited children are not. Own each acquired resource through its teardown; a spec that passes only when run alone is defective, not the runner. [dsh-ci-test-reliability](../.agents/skills/dsh-ci-test-reliability/SKILL.md) owns the allocation, restoration, synchronization, timeout-budget, platform, and teardown rules; its [flake diagnosis workflow](../.agents/skills/dsh-ci-test-reliability/references/ci-flake-diagnosis.md) classifies an existing probabilistic failure.

 - **快照**（`pnpm run test:snapshot`）：顶层场景数值最高的已录制 parent generation 同时提供用户输入和模型回放，并作为持久化结果的预期值。parent 文件名是 `session[.vN].jsonl`；child 角色使用 `session.<ordinal>[.vN].jsonl`；v0 省略 `.v0`，正版本必须使用小写 `.vN`，且每个文件名必须与其 header 一致。进程级场景都通过 `dsh` 启动：headless 负责一次性行为，SDK 负责持久控制，ACP 负责自动化协议行为，Web 在同一 Session 旁保留浏览器与 ARIA 证据。`snapshot.yml` 声明 profile、组合与请求头类别、录制策略、例外回放或输入元数据以及 workspace 事实。带类型的 token 保留父子身份关系；只有请求头 pin 拥有 prompt/schema sidecar。变更 workspace 的场景会独立比较完整的 `workspace.expected/` 目录，record 与 refresh 绝不改写该目录。当模型 transcript（文本记录）变化时使用 `test:snapshot:record`，回放输入仍有效时使用 `test:snapshot:refresh`；请审查所有结果差异。
 - **Web 浏览器快照**（`pnpm run test:web`；必需的 Linux PR（Pull Request）门禁）：Chromium 比较 `snapshots/web/` 下由会话驱动的输出，以及 `apps/web/tests/expected/` 下仅含 UI 的输出。CI 强制只读的 `DSH_SNAPSHOT=replay`，绝不写入预期输出；record/refresh 留在本地，每处 diff 都须评审（[web e2e 车道](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.zh.md)、[CI 门禁决策](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.zh.md)）。`test:web` 会先构建以交付插件 CSS。

 ## spec 如何被执行
 
-fork 出的 worker 会同时运行多个 spec 文件，coverage gate 会拆成并发的 partition，与同一个 job 中的其它 gate 并排运行，而自托管 runner 共用同一台宿主机和同一个卷。被隔离的只有进程：端口、可预测路径、外部命名空间和继承而来的子进程都不隔离。为每个占用的资源负责到它的 teardown；只有单独运行时才通过的 spec 是缺陷，而不是 runner 不稳定。[dsh-ci-test-reliability](../.agents/skills/dsh-ci-test-reliability/SKILL.md) 负责资源分配、状态恢复、同步、超时预算、平台差异与 teardown 规则；它的 [flake 诊断流程](../.agents/skills/dsh-ci-test-reliability/references/ci-flake-diagnosis.md)用于归类已经存在的概率性失败。

 ## Problem
 
-Session format v0 shipped in an alpha release, so a structural writer change can no longer treat existing JSONL as disposable pre-release state. Stored event bodies reach consumers through read or write `SessionHandle` instances used by resume, query, export, fork, and continuation paths. Migrating only one consumer would let callers observe different logical generations or fail only when a later writer reaches the old file.
+Session format v0 shipped in an alpha release, so a structural writer change can no longer treat existing JSONL as disposable pre-release state. The first whole-artifact migration implementation made those logs convertible, but its data model turned a 116 MB real Session into an operation that exhausted a 16 GB Node process before returning a handle.
 
-Migration must retain the exact source path, bytes, and inode, including a torn physical tail, while giving every published format one unambiguous canonical filename. Plain JSONL and Zstandard are encoding choices for the same logical format and must not create parallel migration implementations.
+### Whole-artifact performance failure
+
+- Zstandard input was split into 317,540 frames and each frame used a separate asynchronous decompression call. The implementation retained every plaintext frame and then concatenated them before JSON parsing, creating the same number of Promise, thread-pool, and native decode transitions.
+- Physical Decode materialized a complete plaintext Buffer, one complete string, every JSONL row, expanded source events, migrated target events, encoded target rows, a joined target string, and target physical Buffers at overlapping points in the same request.
+- Every codec and migration edge called `snapshotSessionFormatJson()` or `snapshotSessionFormatArtifact()`. These operations detached, recursively copied, and deeply froze whole headers, rows, payloads, and event arrays before and after adjacent migrations.
+- Released packed Assistant chunks expanded into about 9.14 million logical v0/v1 events before v1-to-v2 folded them into 72,784 current events. The whole-artifact API required both representations and the old-to-new sequence map to coexist.
+- Encoding built the complete JSONL and compressed output in memory. The successful path then decoded the staged target, decoded the committed target, and decoded it again in persistence to construct the business object; it also reread the source for a full fingerprint comparison.
+- Per-frame `await` calls did not provide useful bounded scheduling. The pre-migration reader instead reused one synchronous decoder and yielded from the outer loop about every 500 ms, avoiding hundreds of thousands of asynchronous transitions.
+
+### The interfaces prevented local fixes from composing
+
+`SessionFormatCodec` decoded and encoded complete arrays, each adjacent `SessionFormatMigration` accepted and returned a complete `SessionFormatArtifact`, and the compiled chain could only hand one materialized artifact to the next edge. A faster physical decoder therefore still encountered source-row arrays, expanded-event arrays, per-edge snapshots, and target-row arrays downstream.
+
+The migrations are stateful even though the API presented them as one-shot functions. v0-to-v1 tracks message and retry identity. v1-to-v2 buffers one unsettled Assistant attempt, tracks events blocked behind it, and maintains old-to-new sequence references. Wrapping that state in closures or push/finish helper objects made the runtime structure different from the static declarations and made production, Worker verification, fixtures, and replay use different entry paths.
 
 ## Decision
 
-`SESSION_FORMAT_VERSION` is a monotonic current-writer integer. One profile-independent pure package owns each adjacent `vN -> vN+1` conversion. `@deepseek-ai/dsh-session-format` supplies only lossless snapshots, unique gap-free planning, header-only conversion, and whole-artifact composition; `@deepseek-ai/dsh-session-format-catalog` statically imports the complete chain independently of mounted Cordis plugins. Historical codecs and normalizers live in the named edge package, while current Session and persistence code accept only the latest logical types.
+The Session format packages use a stateful synchronous Stage API. Static migration declarations describe one adjacent version edge and create a new stage for each restored artifact. A stage owns that artifact's mutable state; no stage instance is shared across Sessions.
 
-Each edge freezes strict source and target semantics, while its target physical codec remains vocabulary-neutral so ordinary event growth can stay within one format version. The catalog restores the final generation through the installed peer `@deepseek-ai/dsh-session` and its current `KNOWN_SESSION_EVENT_TYPES`, preventing a frozen historical edge from becoming the current vocabulary owner.
+### Stage and Context protocol
 
-The JSONL provider completes ensure-current work before `open` returns a handle for a stored Session. It selects the highest canonical generation, migrates a supported historical body, and decodes the current result from one physical snapshot; the public `SessionPersistence` and `SessionHandle` interfaces contain no migration operations. Header-only `stat` and `list` rescan Session directories, translate supported historical headers in memory, and never publish a successor. `create` checks canonical filenames independently of header readability, so every existing generation reserves its Session id.
+```text
+interface SessionFormatMigrationContext {
+  emitEvent(event: SessionFormatEvent): void
+  emitRun(run: SessionFormatEventRun): void
+}
 
-Cancellation belongs to the `open`, `stat`, or `list` call that supplied it. Discovery, stable reads, decoding, and pre-publication checks observe that signal; once an immutable successor is published and its directory entry is synced, later cancellation does not delete the committed generation.
+interface SessionFormatMigrationStage {
+  readonly headerInheritedEventCount?: number
+  transformEvent(
+    event: SessionFormatEvent,
+    context: SessionFormatMigrationContext,
+  ): void
+  transformRun(
+    run: SessionFormatEventRun,
+    context: SessionFormatMigrationContext,
+  ): void
+  finish(context: SessionFormatMigrationContext): number
+}
+```
 
-The configured JSONL encoding owns one full suffix, `.jsonl` or `.jsonl.zstd`. Migration reads a stable exact source, decodes the recoverable logical prefix, composes every required edge in memory, validates and syncs a same-directory temporary stage for only the final target, rechecks the source fingerprint, publishes that previously absent target without overwrite, syncs the namespace, and reopens it through current validation before returning a handle. The source never moves or changes; only disposable temporary stages may be moved, linked, or removed. Migration does not synthesize interrupted-turn events: agent-loop appends those repairs through the write handle, while read-only query paths balance them in memory.
+`SessionFormatMigrationContext.emitEvent()` and `emitRun()` are synchronous. The producer declares whether it emits a scalar event or a compact run, so the hot path never infers the category from properties on a parsed file object. The caller owns scheduling and supplies the context to each operation instead of injecting a callback into the stage constructor. One input may emit zero, one, or many outputs without allocating a temporary return array or retaining an internal output queue.
 
-Canonical filenames encode the physical format generation: v0 is `session.jsonl` or `session.jsonl.zstd`; every positive generation is lowercase `session.vN.jsonl` or `session.vN.jsonl.zstd`. `dsh-session-format` owns the raw basename rule (`sessionFormatLogFilename`, `parseSessionFormatLogFilename`); the JSONL provider, the session-log export archive, and recorded-session fixtures append only the compression suffix. Publication never renames, replaces, or deletes a committed generation path. If the target already exists, it is accepted only as a regular current-format file with exactly the expected bytes; any other target refuses. Lower generations remain for operator inspection or explicit copying, but normal runtime operations select the numerically highest canonical name and never use retained predecessors as automatic fallback, restore, or downgrade support.
+`SessionFormatMigration` remains an immutable declaration: version numbers, header migration, target-header validation, and `createStage()`. `CompiledSessionFormatChain` validates a unique gap-free edge sequence once, creates per-artifact stages in source-to-target order, and connects them with context objects in reverse order. `finish()` settles stages in source-to-target order so each stage can emit its tail before the downstream stage closes.
 
-The current-format fast path classifies the header from one stable source snapshot, invokes no historical converter or generation write, and passes that snapshot to current decoding without another file read. The decoded log enters the existing bounded revision-keyed memo for an immediate observe-to-resume handoff, while `stat` and `list` deliberately rescan. Multiple edges leave the original generation unchanged and publish only the final target; intermediate versions exist only in memory. A source fingerprint recheck restarts migration when content changes, and exclusive target publication accepts a racing winner only when its bytes match exactly. Cross-process append fencing remains outside this guarantee.
+```text
+JSONL record
+  → released physical row decoder
+  → v0-to-v1 stage
+  → v1-to-v2 stage
+  → current event collector
+```
 
-The first edge, `@deepseek-ai/dsh-session-format-v0-to-v1`, is intentionally identity-shaped: aside from the version and bounded historical normalizations already accepted by v0, it preserves logical headers, events, sequence numbers, references, timestamps, payloads, and the configured compression choice. The exact `session.jsonl[.zstd]` source remains byte- and inode-identical, while the current writer encodes the new `session.v1.jsonl[.zstd]` successor. This exercises the complete publication lifecycle before a cardinality-changing format needs it.
+The chain contains no `flatMap`, spread expansion, intermediate event array, or scheduler. The final event collector expands a compact run only after every migration stage has had the opportunity to consume it directly.
 
-Projection-cache records bind their fold to the Session header's `formatVersion`. The `session_projcache` v7 reader may load predecessor domain records structurally, but a record without the format generation cannot seed a current Session; the authoritative log refolds it and the next checkpoint writes the complete current identity. This prevents a cache row produced before a bounded normalizer or cardinality-changing edge from bypassing that migration.
+### Physical codecs and packed runs
 
-## Consequences
+Each released codec creates a row decoder with explicit `strict` or `recoverable` recovery. The decoder validates and emits one event or one codec-owned `SessionFormatEventRun` at a time through separate context methods. v0-to-v1 and v1-to-v2 implement both `transformEvent()` and `transformRun()`, so packed Assistant chunks can reach the folding edge without first becoming millions of ordinary events.
 
-Reading event bodies with a newer build may durably add a higher generation. The exact old generation remains available, but the runtime thereafter selects the highest canonical filename; retention does not promise that an older build can safely downgrade or that the newer build will fall back when the successor is corrupt. A read-only filesystem reports an actionable migration failure instead of returning an in-memory current view that differs from disk.
+The v0-to-v1 edge preserves logical headers, sequence numbers, references, timestamps, and payloads except for bounded released-v0 normalizations. It translates the retired `steering/message` and `compact/*` event names, accepts a released `llm/retry` after its matching `step/end`, deterministically supplies a missing `llm/retry.retryId` per turn/step/provider/policy chain, and supplies one deterministic `compactionId` across a legacy compaction group that omitted it. The v1-to-v2 edge owns attempt folding and reference remapping, and emits only settled current events. It splits a legacy goal-sourced user message into `goal/change` plus the original model-visible message. It also inserts an interrupted `turn/end` for the bounded released restart in which an open turn with no open step is followed by a non-empty `next-turn` inbox splice and the next numbered `turn/start`.
 
-JSONL publication uses POSIX hard-link creation plus directory sync, and Windows uses no-overwrite `MoveFileExW` with write-through. A competing writer that wins target creation is accepted only when the committed bytes exactly match. One process-local writer per Session is the supported concurrency model. A future per-Session cross-process lock can close the remaining source-check-to-publication race without changing the format edge interface.
+The catalog exposes one `createRestore()` operation for production, Worker, fixture, and replay callers. Recovery policy and final validation policy are chosen once at restore creation. Historical production uses recoverable source parsing with transformed-current validation; this validates the released current result after migration, while input that is already current receives only codec validation. Worker and fixture verification use strict parsing with full installed current restoration. A migration-stage or transformed-current validation refusal remains `SessionFormatUnsupportedMigrationError`; physical decoding failures remain corruption. Test support keeps only fixture-specific token and envelope materialization.
 
-Retained generations are not a live-stream write-ahead log. A future optional WAL sidecar may preserve unfinished assistant streams across a hard crash. Explicit generation inspection or copying, retention tooling, compression conversion, and streamed whole-artifact transformation are separate features; automatic fallback and downgrade compatibility are not implied future work.
+### JSONL integration
 
-This note supersedes the continue-only persistence rule and the deferred-chain status in [Session log versioning](2026-08-10-session-log-version-mechanism.md). That note remains the authority for when to bump the version and for ordinary equal-version `ignorable` event behavior.
+The JSONL provider scans frame boundaries once, reuses one Zstandard decoder, parses complete JSONL records incrementally, and feeds rows directly into the catalog restore. The outer loop yields at a bounded cadence; there is no per-frame `await` and no complete plaintext or source-row array.
+
+Current encoding is record based. The provider serializes about 1 MiB of plaintext per main-thread slice, streams it through one Zstandard context with source-error propagation, writes compressed output in 4 MiB batches to an exclusively created same-directory temporary file, and syncs it before publication. A process-wide scheduler admits at most two full verification Workers and hands a released permit directly to the oldest waiter.
+
+Cancellation is observed at the existing approximately 500 ms Decode yield boundary and the approximately 1 MiB encode yield boundary. A queued verifier removes its waiter when cancelled; an active verifier terminates its Worker and awaits exit before releasing the permit. This does not make the underlying file writes newly interruptible, and cancellation never rolls back a generation that has already been published.
+
+This decision deliberately preserves the existing serial persistence lifecycle:
+
+```text
+read/write open
+  → decode and migrate historical source
+  → encode and sync temporary current generation
+  → Worker verify
+  → recheck source
+  → publish without overwrite
+  → verify/reopen committed generation
+  → return handle
+```
+
+Read-only preparation and write publication are not separated here. Both handle kinds wait for the current generation. That scheduling problem remains independently changeable without restoring the whole-artifact format API.
+
+### Durable format and publication rules
+
+Canonical filenames encode physical format generation: v0 is `session.jsonl[.zstd]` and positive generations use `session.vN.jsonl[.zstd]`. Migration never moves, replaces, or deletes a committed generation and writes only the final current target; intermediate versions exist only as stage state.
+
+POSIX publication uses hard-link creation plus directory sync. Windows uses no-overwrite, write-through `MoveFileExW`. An existing target is accepted only when its verified migration prefix equals the staged bytes; any append tail belongs to current-generation reading rather than migration winner verification.
+
+Existing write handles retain the process-local claim and kernel-backed cross-process `SessionWriteLease`. Header-only `stat` and `list` translate supported historical headers without opening the body or publishing a generation. Projection-cache records bind their fold to the Session header's format version so a cache row cannot bypass a cardinality-changing migration.
+
+## Problem-to-solution mapping
+
+| Whole-artifact problem | Implemented mechanism | Result |
+|---|---|---|
+| One asynchronous decode call per Zstandard frame | One reusable decoder; outer 500 ms scheduling cadence | Removes 317,540 async transitions |
+| Complete plaintext, string, and row arrays | Incremental JSONL parser and row decoder | Retains only one cross-chunk record fragment |
+| Complete event array between every edge | Context-connected stateful stages | No intermediate version event arrays |
+| Packed chunks expand before folding | `SessionFormatEventRun` plus `transformRun()` | 9.14 million source events need not materialize |
+| Whole-artifact snapshot and deep freeze at every edge | Stage-owned exclusive values and final validation | Removes repeated recursive copy/freeze |
+| One-shot migration functions hide state | Per-artifact stage classes from immutable declarations | State ownership and concurrency are explicit |
+| Bulk current encode builds whole strings and Buffers | Record encoder, 1 MiB input slices, 4 MiB write batches | Bounds allocation and main-thread slices |
+| Verification repeats on the main thread | At most two complete-generation Workers | Keeps verification CPU off the main thread |
+| Production and fixture migration use different APIs | Catalog `createRestore()` with explicit policies | One decoder/chain implementation |
 
 ## Verification
 
-Release verification runs the committed Session-format corpus gate over every versioned persisted-or-projected `session*.jsonl` fixture under `snapshots/`, `packages/`, and `scripts/snapshots/python-sdk-single-exe/`. Fixture-only omitted envelopes and request-header tokens are materialized before the real static catalog; every fixture reaches the current v1 view through current restoration or historical migration. Released-v0 replay inputs remain suffixless, while fresh v1 writer outputs use `session.v1.jsonl` for a parent and `session.<ordinal>.v1.jsonl` for children. Record and refresh preserve every completed generation, including generations of a child role absent from a later run. Malformed historical fixtures are repaired at their source rather than admitted through path-dependent replay policy. The continuing gate discovers the corpus dynamically and fails every restoration refusal; separate assembled JSONL tests own exact physical-byte migration.
+### Benchmark input and meanings
 
-Handle-integration verification runs the pure format, catalog, persistence-seam, and JSONL provider suites together: 420 tests cover both encodings, immutable publication races, header-only observation, read and write handles, migration refusal, append after migration, cancellation, and crash-tail behavior with per-file 100% statement, branch, function, and line coverage. Repository typecheck and lint, 113 keyless recorded-session replays with two declared skips, and 28 owner-local expected-output cases also pass on the merged master checkpoint.
+The benchmark uses Node v24.18.0 and one 116,228,655-byte v0 Zstandard log containing 317,540 frames and 454,151 physical rows. The old reader restores 9,143,111 expanded v0 events. Migration produces 72,784 current v2 events with artifact SHA-256 `fa16ff9472ca350595a3112c20a3db79655bc2673973469987ecaf2a57ebd17c`.
 
-The assembled headless profile test stages `session.jsonl`, resumes it through the shipped composition, observes v1 before Session construction, verifies that the exact v0 bytes and inode remain while `session.v1.jsonl` appears, and proves the next append targets v1. JSONL contract tests exercise raw and Zstandard exclusive publication, torn-tail preservation, source changes, target collisions, future-highest refusal, revision-keyed parsed-log reuse, listing rescans, temporary cleanup, committed reopen, and current-format bypass.
+Runs use built artifacts under plain Node, one process per sample, and a 16 GB V8 heap limit. “Retained heap” is measured after forced GC while the restored Session remains live. Values below are three-run medians except the whole-artifact failure, which consistently cannot reach a handle.
+
+### Physical Decode
+
+| Data path | Decode time | Peak RSS | Scheduling |
+|---|---:|---:|---|
+| Pre-migration optimized reader | 1.553s | 916MB | One decoder; 2–3 outer yields |
+| Whole-artifact migration | 7.527s | 7,219MB | 317,540 async decoder calls |
+| Streaming Stage path | 1.467s | 908MB | One decoder; 2 outer yields |
+
+### Historical-file cold open
+
+| Version | Time to restored Session | CPU time | Peak RSS | Retained heap | Restored events | Outcome |
+|---|---:|---:|---:|---:|---:|---|
+| Pre-migration high-performance v0 reader | 4.594s | 6.048s | 2.720GB | 2.016GB | 9,143,111 | Reads v0; does not migrate |
+| Whole-artifact migration | >72.8s | — | ≥7.219GB during Decode | — | — | OOM before a handle |
+| Streaming Stage migration with serial publication | 6.241s | 8.493s | 2.107GB | 477MB | 72,784 | Publishes and opens v2 |
+
+The old reader has lower one-time wall time because it performs no format conversion or durable publication. It also keeps the 9.14-million-event representation live. The Stage path pays encode and verification once, then retains the folded v2 state.
+
+### Current-format cold open
+
+| Version reading its current format | Time to restored Session | Peak RSS | Retained heap |
+|---|---:|---:|---:|
+| Old reader on v0 | 4.594s | 2.720GB | 2.016GB |
+| Whole-artifact-era reader on v2 | 1.273s | 1.107GB | 476MB |
+| Streaming Stage reader on v2 | 1.284s | 1.109GB | 476MB |
+
+The current-v2 fast path remains performance-equivalent. The architectural change does not route current data through historical stages.
+
+### Streaming serial migration breakdown
+
+| Phase | Median |
+|---|---:|
+| Source Decode and migration | 2.784s |
+| Encode, write, and sync | 0.956s |
+| Full staged-file Worker verification | 1.415s |
+| Source recheck and no-overwrite publication | 0.106s |
+| Committed-prefix verification and header reopen | 0.046s |
+| Generation ensure-current total | 5.318s |
+| Final current decode observed by persistence | 0.620s |
+| Session restoration | 0.594s |
+| End-to-end restored Session | 6.241s |
+
+The generation breakdown and end-to-end table come from separate instrumented runs, so rounded rows are not expected to sum exactly.
+
+Format, catalog, edge, JSONL, fixture, replay, and built-Worker tests cover both encodings, packed runs, header-only classification, torn tails, migration refusal, deterministic legacy normalization, source changes, target collisions, write leases, and Worker failure.
+
+## Consequences
+
+At least one final current-event array remains necessary because Session restoration and Agent execution retain complete history. The Stage architecture removes full source and intermediate target arrays; it does not promise memory proportional to a page window.
+
+Decoded scalar `assistant/chunk` rows receive envelope validation and final target validation, but their complete frozen-v1 source payload-member validation is deferred because that per-event check materially affects Decode and migration time on released logs. Packed Assistant runs remain strictly decoded. The scalar check must be restored only with performance evidence that preserves this migration path's measured behavior.
+
+The serial persistence lifecycle still makes a read open wait for encode, verification, and publication. Separating logical readability from durable write readiness is a follow-up scheduling decision, not another format-pipeline rewrite.
+
+Lower generations remain for operator inspection. Retention does not promise downgrade compatibility, automatic fallback, or that an older runtime can safely interpret a newer generation.
 
 ## Alternatives considered
 
-- **Migrate only on continuation** — leaves query, export, fork, and suffix consumers on old generations and duplicates restoration policy.
-- **Return a migrated in-memory view without persisting** — lets one process observe state that does not match the highest committed generation and postpones failure until a later writer.
-- **Persist every intermediate version** — consumes space and creates recovery states with no runtime consumer; only the source and final generation are durable.
-- **Let mounted event-owner plugins register migrations** — makes historical readability deployment-dependent; the static catalog must work before feature plugins mount.
-- **Reuse one filename for every current format and relocate its predecessor** — rejected because migration would move or overwrite committed evidence, require collision and retention rules, and make the filename disagree with the stored format. Canonical immutable generation names let discovery select the highest version directly.
+- **Optimize only Zstandard Decode** — restores physical Decode speed but leaves source rows, expanded events, snapshots, intermediate artifacts, and bulk encode in memory.
+- **Synchronous Generator stages** — retain execution frames and batches at each yield. Real-log measurements increased migration time and migrate-complete RSS from about 1.0 GB to about 1.2 GB.
+- **Return arrays from each stage** — preserves the old allocation, traversal, and flattening costs under a new name.
+- **Give each stage an internal output queue** — adds drain, EOF, and error ownership while still retaining intermediate values.
+- **Inject an emit callback through constructors** — forces reverse construction or a partially connected lifecycle. Passing a context to operations keeps stage construction independent of downstream wiring.
+- **Share stateful codec instances globally** — would mix pending attempts, mappings, and counters across concurrent Session restores.
+- **Persist every intermediate format version** — creates durable states with no runtime consumer; only the exact source and final current generation are needed.
+- **Let mounted plugins register migrations** — makes historical readability deployment dependent. The static catalog must restore released formats before feature plugins mount.

+- Encode 会在内存中构造完整 JSONL 与压缩输出。成功路径随后 Decode staged target、Decode committed target，并由 persistence 再 Decode 一次以创建业务对象；它还会完整重读 source 以比较 fingerprint。
+- 逐 frame `await` 没有形成有意义的有界调度。迁移前的高性能 reader 会复用一个同步 decoder，只由外层循环约每 500 ms yield 一次，从而避免数十万次异步切换。
+
+### 既有接口使单点优化无法组合
+
+`SessionFormatCodec` 以完整数组 Decode 与 Encode；每条相邻 `SessionFormatMigration` 接收并返回完整 `SessionFormatArtifact`；compiled chain 只能把已经物化的 artifact 交给下一条 edge。因此即使 physical decoder 单点变快，下游仍会重新创建 source-row array、expanded-event array、逐 edge snapshot 与 target-row array。
+
+Migration 实际有状态，但 API 把它们表现为一次性函数。v0-to-v1 需要跟踪 message 与 retry identity；v1-to-v2 需要暂存一个尚未结算的 Assistant attempt、被它阻塞的后续事件，并维护 old-to-new seq 引用。把这些状态隐藏在 closure 或 push/finish helper object 中，会让运行结构与静态声明分离，也让 production、Worker verify、fixture 与 replay 使用不同入口。
 
 ## 决策
 
-`SESSION_FORMAT_VERSION` 是单调递增的当前 writer 整数。每个相邻 `vN -> vN+1` 转换由一个与 profile 无关的纯包负责。`@deepseek-ai/dsh-session-format` 只提供无损快照、唯一且无缺口的规划、仅 header 转换与整产物组合；`@deepseek-ai/dsh-session-format-catalog` 静态导入完整链，不依赖已挂载的 Cordis 插件。历史 codec 和归一化器位于具名迁移边包中，而当前 Session 与持久化代码只接纳最新逻辑类型。
+Session format 包采用有状态同步 Stage API。静态 migration declaration 描述一条相邻版本边，并为每次 artifact restore 创建新的 stage。Stage 拥有该 artifact 的可变状态；不同 Session 之间绝不共享 stage instance。
 
-每条迁移边都会冻结严格的源与目标语义，其目标物理 codec 则保持词汇中立，使普通事件增长可以留在同一格式版本内。目录通过已安装的 peer `@deepseek-ai/dsh-session` 及其当前 `KNOWN_SESSION_EVENT_TYPES` 还原最终代，避免冻结的历史迁移边反过来成为当前词汇 owner。
+### Stage 与 Context 协议
 
-JSONL provider 在 `open` 为已存储 Session 返回句柄前完成 ensure-current 工作。它选择最高规范 generation、迁移受支持的历史正文，并从同一物理快照解码当前结果；公开 `SessionPersistence` 与 `SessionHandle` 接口不包含迁移操作。仅 header 的 `stat` 与 `list` 会重新扫描 Session 目录，在内存中转换受支持的历史 header，且绝不发布后继。`create` 独立于 header 可读性检查规范文件名，因此每个现有 generation 都会占用其 Session id。
+```text
+interface SessionFormatMigrationContext {
+  emitEvent(event: SessionFormatEvent): void
+  emitRun(run: SessionFormatEventRun): void
+}
 
-取消属于提供信号的 `open`、`stat` 或 `list` 调用。发现、稳定读取、解码与发布前检查都会观察该信号；不可变后继一旦发布且其目录项已经同步，后续取消不会删除已提交 generation。
+interface SessionFormatMigrationStage {
+  readonly headerInheritedEventCount?: number
+  transformEvent(
+    event: SessionFormatEvent,
+    context: SessionFormatMigrationContext,
+  ): void
+  transformRun(
+    run: SessionFormatEventRun,
+    context: SessionFormatMigrationContext,
+  ): void
+  finish(context: SessionFormatMigrationContext): number
+}
+```
 
-配置的 JSONL 编码拥有一个完整后缀：`.jsonl` 或 `.jsonl.zstd`。迁移读取稳定的精确源，解码可恢复逻辑前缀，在内存中组合全部必需迁移边，只为最终目标校验并同步同目录临时 stage，重新检查源 fingerprint，以不覆盖方式发布此前不存在的目标，同步 namespace，并在返回句柄前通过当前格式校验重新打开。源永不移动或改变；只有可丢弃临时 stage 可以被移动、链接或移除。迁移不会合成中断轮次事件：agent-loop 通过写句柄追加这些修复，而只读查询路径在内存中补齐它们。
+`SessionFormatMigrationContext.emitEvent()` 与 `emitRun()` 都是同步操作。Producer 会声明其发出单个事件还是紧凑 run，因此热路径不会根据已解析文件对象的属性推断类别。调度归 caller 所有，context 在每次调用时传入，而不是把 callback 注入 stage constructor。一个输入可以输出零个、一个或多个值，不需要分配临时返回数组，也不需要 stage 内部保留输出队列。
 
-规范文件名编码物理格式 generation：v0 是 `session.jsonl` 或 `session.jsonl.zstd`；每个正 generation 都是小写 `session.vN.jsonl` 或 `session.vN.jsonl.zstd`。`dsh-session-format` 拥有原始 basename 规则（`sessionFormatLogFilename`、`parseSessionFormatLogFilename`）；JSONL provider、session-log 导出归档与 recorded-session fixture 只追加压缩后缀。发布绝不重命名、替换或删除已提交 generation 路径。目标已经存在时，只有它是普通当前格式文件且字节与预期完全相同时才接受；其他目标都会拒绝。低 generation 为 operator 检查或显式复制而保留，但普通 runtime 操作选择数值最高的规范名称，绝不把保留的前任当作自动 fallback、restore 或 downgrade 支持。
+`SessionFormatMigration` 继续作为 immutable declaration，声明版本号、header migration、target-header validation 与 `createStage()`。`CompiledSessionFormatChain` 只校验一次唯一、无缺口的 edge 序列，按 source-to-target 顺序创建每次 artifact 独占的 stage，再按反方向用 context 连接它们。`finish()` 按 source-to-target 顺序关闭 stage，使每一级都能在下游关闭前发出尾部数据。
 
-当前格式快速路径从一个稳定源快照分类 header，不调用历史 converter，不写 generation，并把该快照交给当前格式解码，而不再次读取文件。解码日志进入现有按 revision 为键的有界 memo，供紧接的观察到恢复交接复用，而 `stat` 与 `list` 会有意重新扫描。多条迁移边保持原 generation 不变，并只发布最终目标；中间版本只存在于内存。源 fingerprint 重新检查会在内容变化时重启迁移，排他目标发布只在竞争胜者字节完全相同时接受它。跨进程 append 隔离不在此保证内。
+```text
+JSONL record
+  → released physical row decoder
+  → v0-to-v1 stage
+  → v1-to-v2 stage
+  → current event collector
+```
 
-第一条迁移边 `@deepseek-ai/dsh-session-format-v0-to-v1` 有意保持恒等形态：除版本和 v0 已接纳的有限历史归一化外，它保留逻辑 header、事件、序号、引用、时间戳、payload 与已配置的压缩选择。精确的 `session.jsonl[.zstd]` 源保持字节与 inode 相同，当前 writer 则编码新的 `session.v1.jsonl[.zstd]` 后继。这样可在出现改变基数的格式前先验证完整发布生命周期。
+Chain 中不存在 `flatMap`、spread expansion、中间 event array 或 scheduler。只有在每个 migration stage 都已获得直接消费 compact run 的机会后，最终 event collector 才会展开它。
 
-投影缓存记录把自己的折叠结果绑定到 Session header 的 `formatVersion`。`session_projcache` v7 reader 可以在结构上载入前代 domain 记录，但缺少格式代的记录不能播种当前 Session；权威日志会重新折叠它，下一次检查点写入完整的当前 identity。这样，任何在有界规范化或基数变化边之前产生的缓存行都不能绕过该迁移。
+### Physical codec 与 packed run
 
-## 后果
+每个 released codec 会用显式 `strict` 或 `recoverable` 策略创建 row decoder。Decoder 每次通过不同的 context 方法校验并 emit 一个 event 或 codec-owned `SessionFormatEventRun`。v0-to-v1 与 v1-to-v2 都实现 `transformEvent()` 和 `transformRun()`，因此 packed Assistant chunk 可以直接到达 folding edge，无需先变成数百万个普通事件。
 
-较新 build 读取事件正文时可能持久增加一个更高 generation。精确旧 generation 仍然可用，但 runtime 此后选择最高规范文件名；保留不承诺旧 build 能安全 downgrade，也不保证新 build 在后继损坏时 fallback。只读文件系统会报告可操作的迁移失败，而不会返回与磁盘不一致的内存当前视图。
+v0-to-v1 除了有限的 released-v0 归一化外，会保留逻辑 header、seq、引用、时间戳与 payload。它转换已移除的 `steering/message` 与 `compact/*` 事件名称，接受出现在对应 `step/end` 之后的已发布 `llm/retry`，按 turn／step／provider／policy chain 为缺失的 `llm/retry.retryId` 确定性补值，并为省略 id 的旧 compaction group 确定性补充同一个 `compactionId`。v1-to-v2 负责 attempt folding 与引用重写，并且只 emit 已结算的 current event。它会把旧的 goal 来源 user message 拆成 `goal/change` 与原本的模型可见 message。它还会为一种有限的已发布 restart 插入 interrupted `turn/end`：一个没有 open step 的 open turn 后出现非空 `next-turn` inbox splice，随后直接开始编号连续的下一轮。
 
-JSONL 发布在 POSIX 上使用硬链接创建与目录同步，在 Windows 上使用 write-through 且不覆盖的 `MoveFileExW`。竞争 writer 已先创建目标时，只有已提交字节完全匹配才接受。每个 Session 只支持一个进程内 writer。未来逐 Session 跨进程锁可以关闭剩余的源检查到发布竞态，而无需改变格式迁移边接口。
+Catalog 为 production、Worker、fixture 与 replay 暴露同一个 `createRestore()`。Recovery policy 与最终 validation policy 在 restore 创建时一次确定。Historical production 使用 recoverable source parsing 与 transformed-current validation；这种策略会在迁移后校验已发布 current 结果，而已经是 current 的输入只接受 codec 校验。Worker 与 fixture verification 使用 strict parsing 与已安装 current 格式的完整 restoration。Migration stage 或 transformed-current validation 的拒绝会保持为 `SessionFormatUnsupportedMigrationError`；物理解码失败仍是 corruption。Test support 只保留 fixture 自身需要的 token 和 envelope materialization。
 
-保留的 generation 不是实时流 WAL。未来可选 WAL sidecar 可以在硬崩溃间保留未完成 assistant 流。显式 generation 检查或复制、保留策略工具、压缩转换与流式整产物转换都是独立功能；自动 fallback 与 downgrade compatibility 并非隐含 future work。
+### JSONL 串联
 
-本记录取代 [Session 日志版本机制](2026-08-10-session-log-version-mechanism.zh.md) 中仅在继续时持久化和迁移链仍推迟的规则。原记录继续负责何时递增版本，以及普通同版本 `ignorable` 事件行为。
+JSONL provider 只扫描一次 frame boundary，复用一个 Zstandard decoder，增量解析完整 JSONL record，并把 row 直接送入 catalog restore。外层循环按有界 cadence yield；不存在逐 frame `await`、完整 plaintext 或 source-row array。
+
+Current encode 以单条 record 为单位。Provider 在主线程每个 slice 序列化约 1 MiB plaintext，通过一个会传播 source error 的 Zstandard context 流式压缩，以 4 MiB batch 写入同目录排他创建的临时文件，并在 publication 前 sync。进程级 scheduler 最多允许两个完整 verification Worker 并行，并把释放的 permit 直接交给最早的 waiter。
+
+Cancellation 会在现有的约 500 ms Decode yield 边界和约 1 MiB encode yield 边界被观察到。排队 verifier 在取消时会移除自己的 waiter；活动 verifier 会终止 Worker，并等待其退出后再释放 permit。该行为不会让底层文件写入新增可中断能力，取消也绝不会回滚已经发布的 generation。
+
+本决策有意保持既有串行 persistence lifecycle：
+
+```text
+read/write open
+  → decode and migrate historical source
+  → encode and sync temporary current generation
+  → Worker verify
+  → recheck source
+  → publish without overwrite
+  → verify/reopen committed generation
+  → return handle
+```
+
+这里不拆分 read-only preparation 与 write publication。两种 handle 都会等待 current generation 完成。该调度问题可以独立调整，不需要恢复 whole-artifact format API。
+
+### Durable format 与 publication 规则
+
+规范文件名编码 physical format generation：v0 使用 `session.jsonl[.zstd]`，正 generation 使用 `session.vN.jsonl[.zstd]`。Migration 不会移动、覆盖或删除任何 committed generation，并且只写最终 current target；中间版本只存在于 stage state。
+
+POSIX publication 使用 hard-link creation 加目录 sync；Windows 使用 no-overwrite、write-through 的 `MoveFileExW`。已有 target 只有在其已校验 migration prefix 等于 staged bytes 时才会被接受；任何 append tail 都属于 current-generation reader，而不是 migration winner verification。
+
+既有 write handle 继续使用进程内 claim 与内核支持的跨进程 `SessionWriteLease`。仅 header 的 `stat` 与 `list` 可以转换受支持的历史 header，但不打开 body，也不发布 generation。Projection-cache record 会把 fold 绑定到 Session header 的 format version，使 cache row 不能绕过改变 event 基数的 migration。

 ## 验证
 
-发布验证针对 `snapshots/`、`packages/` 与 `scripts/snapshots/python-sdk-single-exe/` 下每个带版本、来自持久化或投影的 `session*.jsonl` fixture 运行已提交 Session 格式语料门禁。fixture 专用的缺失信封与 request-header token 会先被实体化，再进入真实静态 catalog；每个 fixture 都会通过当前格式 restore 或历史迁移得到当前 v1 视图。Released-v0 replay 输入保持无后缀，而新鲜 v1 writer 输出对 parent 使用 `session.v1.jsonl`、对 child 使用 `session.<ordinal>.v1.jsonl`。Record 与 refresh 会保留每个已完成 generation，包括后续运行不再产生的 child role generation。Malformed 历史 fixture 在来源处修复，不通过依赖路径的 replay 策略准入。持续运行的门禁会动态发现语料，并拒绝每个 restore failure；独立组装式 JSONL 测试负责精确物理字节迁移。
+### Benchmark 输入与口径
 
-句柄集成验证会一起运行纯格式、catalog、持久化 seam 与 JSONL provider 测试套件：420 个测试覆盖两种编码、不可变发布竞态、仅 header 观察、读写句柄、迁移拒绝、迁移后 append、取消与崩溃尾部行为，并达到逐文件 100% statement、branch、function 与 line coverage。仓库 typecheck 与 lint、含两个已声明 skip 的 113 个无密钥 recorded-session replay，以及 28 个 owner-local expected-output case 也都在合并 master 的 checkpoint 上通过。
+Benchmark 使用 Node v24.18.0 和一份 116,228,655-byte 的 v0 Zstandard 日志，其中包含 317,540 个 frame 与 454,151 个 physical row。老 reader 会恢复 9,143,111 个展开后的 v0 event；migration 会生成 72,784 个 current v2 event，artifact SHA-256 为 `fa16ff9472ca350595a3112c20a3db79655bc2673973469987ecaf2a57ebd17c`。
 
-组装后的 headless profile 测试会暂存 `session.jsonl`，通过随附组合恢复它，在构造 Session 前观察到 v1，验证精确 v0 字节与 inode 保持不变而 `session.v1.jsonl` 出现，并证明下一次 append 以 v1 为目标。JSONL 约定测试覆盖 raw 与 Zstandard 排他发布、撕裂尾部保留、源变化、目标冲突、最高未来版本拒绝、按 revision 复用已解析日志、列表重新扫描、临时文件清理、已提交重开与当前格式直通。
+所有样本均通过 plain Node 运行 build artifact，每个样本使用独立进程，V8 heap limit 为 16 GB。“Retained heap”表示 restored Session 仍存活时强制 GC 后的 heap。除无法得到 handle 的 whole-artifact 失败外，下表使用三次运行中位数。

+
+老 reader 的一次性 wall time 更低，因为它不做格式转换和 durable publication；同时它会常驻 914 万 event 的表示。Stage 路径只多支付一次 encode 与 verification，随后保留折叠后的 v2 state。
+

+| Streaming Stage reader 读取 v2 | 1.284s | 1.109GB | 476MB |
+
+Current-v2 快路径保持性能等价。架构改造不会让 current data 进入 historical stage。

+
+## 后果
+
+最终 current-event array 仍然不可消除，因为 Session restore 与 Agent 执行需要完整历史。Stage 架构删除完整 source 与中间 target array，但不承诺内存与分页窗口大小成正比。
+
+解码后的单条 `assistant/chunk` 会接受 envelope 校验与最终 target 校验，但其完整冻结 v1 source payload 成员校验仍处于延期状态，因为这项逐事件检查会显著影响已发布日志的 Decode 与 migration 耗时。Packed Assistant run 仍接受严格解码。只有性能证据表明不会破坏该迁移路径的已测表现时，才能恢复单条 chunk 校验。
+
+串行 persistence lifecycle 仍会让 read open 等待 encode、verification 与 publication。把逻辑 readable 与 durable writable 分开属于后续调度决策，不需要再次改写 format pipeline。
+
+低 generation 为 operator 检查而保留。Retention 不承诺 downgrade compatibility、automatic fallback，也不保证旧 runtime 能安全理解新 generation。
 
 ## 考虑过的替代方案
 
-- **只在继续时迁移**——让查询、导出、分叉与后缀消费者停留在旧代际，并重复恢复策略。
-- **返回迁移后的内存视图但不持久化**——让进程观察到与最高已提交 generation 不一致的状态，并把失败推迟到后续 writer。
-- **持久化每个中间版本**——消耗空间并产生没有 runtime 消费者的恢复状态；只有源与最终代际应持久。
-- **让已挂载事件 owner 插件注册迁移**——使历史可读性依赖部署；静态 catalog 必须在功能插件挂载前工作。
-- **让每个当前格式复用同一个文件名并迁走前任**——不予采用，因为迁移会移动或覆盖已提交证据，需要冲突与保留规则，并让文件名与存储格式不一致。规范不可变 generation 名让发现流程直接选择最高版本。
+- **只优化 Zstandard Decode**——可以恢复 physical Decode 速度，但 source rows、expanded events、snapshot、intermediate artifact 与 bulk encode 仍会留在内存中。
+- **同步 Generator stage**——每个 yield 都会保留执行帧与 batch。真实日志测量使 migration 更慢，并让 migrate-complete RSS 从约 1.0 GB 增长到约 1.2 GB。
+- **每个 stage 返回数组**——只是给旧的 allocation、遍历与 flattening cost 换了名字。
+- **Stage 内部输出队列**——增加 drain、EOF 与 error ownership，同时仍会保留中间值。
+- **通过 constructor 注入 emit callback**——迫使 chain 反向构建或引入 partially connected lifecycle。操作时传 context 可以让 stage construction 不依赖下游 wiring。
+- **全局复用有状态 codec instance**——会让不同 Session 的 pending attempt、mapping 与 counter 相互污染。
+- **持久化每个中间格式版本**——产生没有 runtime consumer 的 durable state；只需要精确 source 与最终 current generation。
+- **让 mounted plugin 注册 migration**——使历史可读性依赖部署。Static catalog 必须在 feature plugin 挂载前恢复已发布格式。

+Current logs, telemetry, and history pages scale by model attempts rather than token chunks while retaining exact stream evidence inside each settlement. The Client event window retains that compact evidence, but the Chat and Trajectory Assistant nodes do not expand settled streams into per-delta objects. Live presentation remains incremental and intentionally process-local.
 
 Unlike v1 top-level chunks, which the buffered persistence writer could flush before an attempt ended, v2 has no durable attempt evidence until settlement. A hard process or host loss before settlement discards the complete in-flight stream; `agent/assistant-stream` is not a write-ahead log. This tradeoff avoids a second durability owner for live output.

+Production historical reads select `{ recovery: 'recoverable', validation: 'transformed' }`. Worker and fixture verification select `{ recovery: 'strict', validation: 'current' }`. Transformed validation runs the released-current rules after migration but deliberately skips installed semantic validation for input that is already current.
 
 The catalog contains all supported historical readers directly. A profile cannot add, remove, or reorder an edge by mounting a feature plugin. Its peer dependency on `dsh-session` supplies the installed current event vocabulary and current restoration rules, while historical edge validators remain frozen.

The edge preserves validated header and event facts except for `version: 0` becoming `version: 1`; it also applies the finite legacy normalizers that v0 persistence accepted. The package freezes the v0 reader, the strict v1 migration target validator, and a vocabulary-neutral v1 physical codec that a later edge can reuse without importing the latest Session representation. Most of its source is the frozen released v0/v1 event vocabulary rather than the identity conversion: `payload-validation.ts` and `relationships.ts` pin the payload members and lifecycle pairings of every first-party event type, so a malformed historical log is refused as an unsupported migration with its source retained before the installed current restorer runs, and a later edge that restructures released events can trust their shapes without importing the current Session package.

+`releasedV0SessionFormatCodec` reads the exact v0 header and physical rows, including packed Assistant deltas and range-encoded provenance. Its decoder emits either a scalar event or a codec-owned compact run through `emitEvent()` and `emitRun()`. `sessionFormatV0ToV1` creates one stateful stage per restore; the static catalog connects that decoder and stage so migration does not retain a physical-row array. `releasedV1SessionFormatCodec` exposes the same row-at-a-time decoder for the v1 physical layout without freezing the ordinary event vocabulary.
 
 The alpha edge refuses every event type outside its frozen inventory, including an unknown event marked `ignorable: true`.

 ## Summary
 
-`dsh-session-format-v1-to-v2` converts a complete released-v1 Session into the released-v2 event model. It consumes top-level `assistant/chunk` events, embeds their exact timed stream in the matching `assistant/message`, and records an `assistant/attempt` when a failed, retried, cancelled, or stream-error attempt reached settlement without a surface message. The edge densely remaps surviving events and every declared same-Session sequence reference, while the v2 codec stores one event per row and derives the inherited cut from a tagged `session/end-seed` marker.

 ### When to use it
 
-Persistence obtains this edge through `dsh-session-format-catalog`; feature compositions do not mount it. Import it directly only when assembling or testing the static released-format catalog or inspecting the exact v1-to-v2 transformation. No runtime invariant companion is published because every codec and migration call validates its complete source or target artifact and retains no runtime state.
+Persistence obtains this edge through `dsh-session-format-catalog`; feature compositions do not mount it. Import it directly only when assembling or testing the static released-format catalog or inspecting the exact v1-to-v2 transformation. No runtime invariant companion is published because the package has no independently observable runtime registrations whose state can diverge; decoder and transformer state belongs to one restore.
 
 ### Entry point
 
 ```text
-const decodedV1 = releasedV1SessionFormatCodec.decodeArtifact(header, rows)
-const migratedV2 = sessionFormatV1ToV2.migrate(decodedV1)
+const decoder = releasedV1SessionFormatCodec.createDecoder(physicalHeader, 'strict')

+const eventRecord = releasedV2SessionFormatCodec.encodeEvent(currentEvent)
 ```
 
-`releasedV1SessionFormatCodec` reads the frozen v1 physical language. `sessionFormatV1ToV2` validates that complete source, performs the cardinality-changing transformation, remaps declared references, and validates the exact v2 result. `releasedV2SessionFormatCodec` then encodes or decodes the current physical representation.
+`releasedV1SessionFormatCodec` reads the frozen v1 physical language one row at a time. `sessionFormatV1ToV2` creates the cardinality-changing Stage that the static catalog connects to that decoder without retaining a v1 event array. The catalog remaps declared references and validates the released-v2 envelope, inherited cut, event admission, and relationships. Persistence applies full installed-current validation in its Worker before publication. `releasedV2SessionFormatCodec` creates a current row decoder and encodes current headers and events one record at a time.
 
 A successful v1 `assistant/message` must cite its complete ordered attempt. The migration removes the cited top-level chunks and obsolete message provenance, compacts the chunks without joining token boundaries, and stores the stream on that message. An unclaimed attempt becomes one log-only `assistant/attempt` at its final chunk position. Unrelated interleaved events keep their relative order.
 
+The edge also closes the bounded legacy restart pattern in which a non-empty `next-turn` inbox insertion is followed by the next `turn/start` without the prior `turn/end`. It records that prior turn as interrupted. A legacy round-zero goal mutation becomes a `goal/change` followed by the original model-visible message with ordinary plugin attribution, so both durable goal state and historical model input survive.
+
 The migration refuses a reference to a consumed chunk instead of redirecting it to a different semantic event. It remaps declared event provenance, surface replacements, command source events, compaction ranges and lists, and title message lists. The already model-visible `session/title-llm-request.messages` text remains byte-identical after source validation, so target validation does not reinterpret the old sequence numbers embedded in that prompt. A seeded source also refuses an inherited cut that splits an Assistant attempt; the target marks the exact cut with `session/end-seed { inherited: true }`.
 
-The v2 physical header requires `isSeeded` and does not store a numeric cut. The codec derives the cut from the last inherited end-seed marker, writes one event per row, range-encodes only `sourceEventSeqs`, and remains neutral to ordinary event vocabulary and payload growth. Strict migration-target validation freezes the released-v2 inventory and rejects unknown types or members. Current restoration instead admits event types known to the installed Session package plus unknown events carrying `ignorable: true`, then delegates payload and stream semantics to the installed current restorer. All paths retain strict header, event-envelope, sequence, and inherited-cut validation.

 ### When to use it
 
-Use this library from persistence or format-catalog code that must classify a physical Session header, restore current logical values, or compose released adjacent migrations. It is not a Cordis plugin and has no profile mount row. No runtime invariant companion is published because every operation validates its borrowed artifact before returning and retains no cross-call mutable state.
+Use this library from persistence or format-catalog code that must classify a physical Session header, restore current logical values, or compose released adjacent migrations. It is not a Cordis plugin and has no profile mount row. No runtime invariant companion is published because each completed operation validates its result; decoder and transformer state belongs to one unfinished streaming restore and is never shared across restores.

-`createSessionFormatCatalog()` accepts one frozen decoder per supported version, the current format's encoder, one migration per adjacent version pair, and current artifact and header restorers. `readHeader()` returns a `current`, `migration-required`, `unsupported`, or `malformed` descriptor without reading events. Each edge validates its target header before the final current-header restorer runs. Body readers call `decodeArtifact()` or `decodeRecoverableArtifact()`, then `migrate()`; writers call `encodeCurrent()` only with a validated current artifact. Frozen v0/v1 codec exports retain their format-specific `packChunks` option without adding that historical control to the current writer or common decoder interface.

+The `recovery` option selects strict row failure or recoverable suffix handling. `validation: 'current'` applies all installed current-format validation. `validation: 'transformed'` applies released current-format validation after historical migration, while already-current input receives only its codec's physical validation.

 ### Durability and crash semantics
 
-A session is materialized lazily: `create(header)` writes nothing and returns the owned write handle, and the handle's first `append` writes and `fsync`s the encoded header and first batch through a no-overwrite publish — so a created-but-never-appended session leaves nothing on disk unless its owner calls `handle.flush()`, which publishes one header frame without an event. Each subsequent batch appends lines or one compressed frame and `fsync`s before the append resolves; a caught write or sync failure rolls the file back to its prior length. Committed events are never rewritten. After a crash, the stored log keeps its interrupted final turn — every record in the committed prefix survives, and the resuming reader appends synthetic closers through its write handle. A torn tail — an incomplete final line, or a torn final frame — is never returned to a reader and is discarded whole, truncated durably before the write handle's first new append, because its own append never resolved and nothing in it was acknowledged durable; checksum, decompression, or structural failure in the committed prefix rejects as corruption.

Committed events are never rewritten. After a crash, the stored log keeps its interrupted final turn — every record in the committed prefix survives, and the resuming reader appends synthetic closers through its write handle. An incomplete final raw line is discarded. A torn final Zstandard frame contributes only its complete decoded JSONL records; a write handle truncates the torn bytes and durably rewrites those recovered records before its first new batch. Checksum, decompression, or structural failure in a complete committed frame rejects as corruption.
 
 ### Reading the logs
 
-`open(id, 'read'|'write')` selects the highest canonical generation and publishes a current successor beside a supported historical source before returning the handle; the source remains byte-identical. The handle's `read(offset?, length?)` then serves validated contiguous slices, never a torn tail. A torn final Zstandard frame is partially decoded: complete JSONL records already flushed into it are recovered into the logical log, and the write handle's first mutation truncates current-generation torn bytes and durably rewrites the recovered records ahead of its own batch. A write open primes the handle with the validated stored prefix, and a bounded revision-keyed memo lets an immediate observe-to-resume handoff reuse that parse. `stat(id)` and `list()` select and translate only the highest generation header without reading event rows or publishing migration output; snapshots carry `sizeBytes` and a best-effort stat-derived revision for the selected file. With `compression: 'none'`, the log is newline-delimited text an external reader can consume directly; the compressed default must be read through the backend.
+`open(id, 'read'|'write')` selects the highest canonical generation. Current input follows the ordinary fast path. Before either kind of handle returns for historical input, the backend decodes and migrates the source once, encodes a same-directory temporary file in bounded chunks, verifies it in a Worker Thread, rechecks the source revision, publishes the current successor without overwrite, and verifies and reopens the committed generation. The source remains byte-identical. The handle's `read(offset?, length?)` serves validated contiguous slices under the durability rules above. A write open primes the handle with the validated stored prefix, and a bounded revision-keyed memo lets an immediate observe-to-resume handoff reuse that parse. `stat(id)` and `list()` select and translate only the highest generation header without reading event rows or starting migration; snapshots carry `sizeBytes` and a best-effort stat-derived revision for the selected file.

 ### Design concept
 
-The backend owns its complete storage runtime (`src/storage.ts`): `JsonlSessionHandle` carries the per-handle mutation chain, the routed live-event buffer with its fixed batching window and single-flight drain, monotonic reads, and idempotent close; a tracker holds the in-process single-writer claims, the open-handle set teardown sweeps, and the created-but-unmaterialized pending sessions the backend's own session listeners route into. The package deliberately exposes only its default plugin export plus configuration types — the concrete class is not a named export, so consumers couple to `ctx.sessionPersistence`, and the shared seam suites (`runPersistenceContract`/`runLiveWritePathContract`) pin its observable behavior. Its change token is a best-effort file revision: device, inode, size, and nanosecond timestamps identify one log for `stat`/`list` and for the stable-read loop that retries a read torn by a concurrent append.

 ### Physical encoding
 
-The default artifact is a standard concatenation of independent [Zstandard frames](../../../.agents/notes/implemented/architecture/2026-07-19-zstandard-jsonl-session-logs.md): one checksummed frame containing only the header line, then one checksummed frame per durable append batch, using Node's built-in Zstandard API at its default compression level (no level knob). Current v2 writes one event per row; `sourceEventSeqs` uses a lossless storage representation in which consecutive runs of at least three sequence numbers become `[start, end]` pairs, any other list stays verbatim, and reading expands the exact in-memory array. Listing reads and validates only the header frame. `compression: 'none'` keeps the same storage-form logical lines without frame compression. A root belongs to one encoding: startup discovery and targeted lookup reject generations with the other suffix; format migration preserves the configured encoding, while compression conversion, mixed-root fallback, and dual write remain unsupported. Frozen v0 and v1 codecs retain their packed-row decoders solely for historical generations.

 **The writer decides bumps, not the reader.** A bump is required exactly when an old runtime could no longer handle a new log with full semantic correctness. "Parses without error" is not the bar: silently skipping content that shapes reconstruction is a wrong read. Only structural changes qualify — header shape, event envelope, core event semantics, the surface mechanism (`SurfaceEventType` set, `SurfaceOp` variants). When unsure, bump: a near-identity upgrader is almost free, a missed bump silently corrupts old readers.
 
-**Read rules by direction.** Equal version: read normally. Newer than the reader: refuse, name the direction ("written by a newer harness — upgrade"), and point at the raw log artifact so the user can still see the text (`SessionFormatUnsupportedError`, distinct from `SessionPersistenceCorruptionError` because nothing is damaged). Older than the reader: every event-body operation first runs the complete adjacent chain in memory, leaves the source path, bytes, and inode unchanged, exclusively publishes only the final current generation under its canonical versioned filename, and reopens it before current restoration. Header-only listing remains non-mutating and reports the numerically highest canonical generation. Catalog generation and module initialization reject a missing adjacent step, so a published first-party build never exposes a partial historical chain. Retained lower generations are not automatic fallback or a downgrade compatibility promise.

Older than the reader: every event-body operation first runs the complete adjacent chain in memory and leaves the source path, bytes, and inode unchanged. Read handles may consume that current logical result directly; a write open exclusively publishes the final current generation under its canonical versioned filename before append. Header-only listing remains non-mutating and reports the numerically highest canonical generation. Catalog generation and module initialization reject a missing adjacent step, so a published first-party build never exposes a partial historical chain. Retained lower generations are not automatic fallback or a downgrade compatibility promise.
 
 **A per-event `ignorable` marker covers vocabulary growth, so ordinary event additions never bump the version.** The event vocabulary is decided by which plugins are mounted, which a single version integer cannot describe. A reader meeting an unrecognized event type refuses to interpret the log unless the event carries `ignorable: true` in its envelope. The default is *required*: forgetting the marker over-refuses a resumable session (an inconvenience), while a default of ignorable would make the same mistake silently resume a gutted one (a safety failure). The architecture makes this sound: model-visible content flows only through the three `surfaceOp`-marked surface event types plus the `request/header`/`request/context` folds, so the dangerous unknowns are exactly the non-surface events that change how the rest of the log is read (`session/end-seed` is the existing example).
 
 ## Consequences
 
-What shipped in v0 (release 0812): direction-aware refusal with the raw-log path; the unknown-event guard against a generated known-vocabulary list (`KNOWN_SESSION_EVENT_TYPES`, emitted by `gen-persistence-catalog` from every `SessionEventMap` merge and kept fresh by `verify-persistence-catalog`); the `ignorable` envelope field accepted by seed validation, JSONL, and the BFF wire schema. V1 adds the static adjacent catalog, the identity v0-to-v1 edge, header-only descriptors, exact-generation JSONL publication, and current-only restoration described in [Released Session formats](2026-08-31-released-session-format-migrations.md). V2 keeps the physical codec neutral to ordinary event vocabulary and payload additions: the adjacent edge freezes its released source and target inventories, while equal-version restoration applies the installed known-event set and current payload semantics. First-party writers do not set `ignorable` through `Session.append`, while a repository-external plugin is a current consumer; equal-version retention lives in the [external-plugin retention decision](2026-08-30-retain-ignorable-external-session-events.md), and the stricter historical rule lives in the [alpha migration refusal decision](2026-08-31-alpha-historical-unknown-event-refusal.md). The unknown-type guard remains read-side because append-time vocabulary refusal would stall a live session's durability. JSONL classifies foreign versions from the minimal raw header before current-header or event parsing, so a structurally different future format reports the upgrade direction instead of "corrupt".

 Current encoding is record based. The provider serializes about 1 MiB of plaintext per main-thread slice, streams it through one Zstandard context with source-error propagation, writes compressed output in 4 MiB batches to an exclusively created same-directory temporary file, and syncs it before publication. A process-wide scheduler admits at most two full verification Workers and hands a released permit directly to the oldest waiter.
 
-Cancellation is observed at the existing approximately 500 ms Decode yield boundary and the approximately 1 MiB encode yield boundary. A queued verifier removes its waiter when cancelled; an active verifier terminates its Worker and awaits exit before releasing the permit. This does not make the underlying file writes newly interruptible, and cancellation never rolls back a generation that has already been published.
+Preparation forwards cancellation through source reads and observes it at the existing approximately 500 ms Decode yield boundary. Once `publish()` starts, encode, Worker verification, and publication do not receive caller cancellation and run to settlement; write open checks its caller signal again afterward. A published generation is never rolled back.
 
-This decision deliberately preserves the existing serial persistence lifecycle:
-
-```text
-read/write open
-  → decode and migrate historical source
-  → encode and sync temporary current generation
-  → Worker verify
-  → recheck source
-  → publish without overwrite
-  → verify/reopen committed generation
-  → return handle
-```
-
-Read-only preparation and write publication are not separated here. Both handle kinds wait for the current generation. That scheduling problem remains independently changeable without restoring the whole-artifact format API.
+The Stage pipeline ends at one prepared current artifact. [Historical Session read preparation](2026-09-05-read-only-session-migration-preparation.md) defines how read open consumes that artifact immediately while write open performs encode, verification, and publication before returning append access.

+Read-only access consumes the Stage result before durable publication, while write open reuses the same result and waits for publication before append. The persistence scheduling remains independent from the format pipeline.
 
 Lower generations remain for operator inspection. Retention does not promise downgrade compatibility, automatic fallback, or that an older runtime can safely interpret a newer generation.

+# Agent Note: Historical Session reads prepare before write publication
+
+Status: implemented
+
+English | [中文](2026-09-05-read-only-session-migration-preparation.zh.md)
+
+## Problem
+
+The stateful Stage pipeline makes historical Decode and migration bounded and fast, but a serial persistence open still performs encode, sync, Worker verification, publication, and committed reopen before returning either handle kind. A read-only consumer therefore waits for about 2.2 seconds of work that it does not need and mutates storage merely to display history.
+
+### Serial readiness cost
+
+- History pagination, projection preparation, export, and the opening `session.follow` snapshot need only the validated current logical artifact.
+- A historical read open nevertheless creates and syncs a temporary v2 generation, starts a full verification Worker, rechecks the source, publishes v2, and reopens the target.
+- The migration result already exists in memory before encode, but the serial API returns only the committed physical snapshot. Persistence must Decode current bytes again to reconstruct the same logical events.
+- `session.follow` cannot deliver its opening snapshot until publication completes, even though Agent resume is the first operation that requires append access.
+- Read-only storage cannot serve a logically valid historical Session because read open requires generation publication.
+
+### A naive split would break lifecycle guarantees
+
+- Returning a write handle before verification would route append into an unpublished temporary file and create a second durability state for accepted events.
+- Starting publication automatically after every read would require backend ownership for task failure, shutdown, cleanup, and a later writer joining work it did not request.
+- A shared preparation cannot inherit the first caller's AbortSignal. One cancelled reader must not terminate work still awaited by another.
+- A read handle must initially serve prepared memory but later observe a current file and its appended tail after another caller publishes.
+- Once readers have observed one prepared artifact, source drift cannot silently rerun migration and substitute a different logical history.
+
+## Decision
+
+The JSONL backend separates logical preparation from durable publication. Read open waits only for preparation. Write open reuses a matching preparation and waits for publication before returning a writable handle.
+
+### Prepared generation API
+
+```text
+interface PreparedJsonlMigration {
+  readonly sourceIdentity: JsonlPhysicalIdentity
+  readonly artifact: SessionFormatArtifact
+  publish(): Promise<JsonlPhysicalIdentity>
+}
+```
+
+`prepareJsonlMigration()` reads one stable historical revision, runs the complete Stage chain once, and returns the current artifact without encoding or writing. `publish()` is idempotent: concurrent and later calls share one terminal Promise, including its rejection, and cannot encode the same prepared artifact twice.
+
+`publish()` streams current records into an exclusively created same-directory temporary file, syncs it, awaits the bounded Worker verifier, compares the source identity captured by preparation, and publishes the canonical path without overwrite. The successful publisher reuses the prepared logical artifact instead of decoding its target. A losing publisher verifies that the winner begins with the exact staged migration prefix; append tail validation remains a current-reader responsibility.
+
+Publication runs to settlement after invocation and is not cancelled midway by the write caller. Write open checks its caller signal before and after publication, so an abort can reject the open after the successor commits without leaking the write lease. A source identity change throws `JsonlGenerationSourceChangedError`, removes the temporary file, and does not repeat Decode or migration.
+
+### Preparation ownership and cancellation
+
+The persistence backend keeps one in-flight entry per Session id, selected source path, and stat-derived revision:
+
+```text
+interface MigrationPreparation {
+  sourcePath: string
+  sourceRevision: SessionPersistenceRevision
+  controller: AbortController
+  promise: Promise<PreparedStoredLog>
+  settled: boolean
+  waiters: number
+}
+```
+
+A new read or write open joins the existing entry only when its source path and revision still match. `waitWithAbort()` races each caller's AbortSignal against the shared Promise without forwarding that signal to shared work. The backend-owned controller is aborted only when the last waiter leaves while preparation is still running.
+
+Completed results enter the existing bounded `coldLogMemo`. The `StoredLog` discriminant separates published current state from `PreparedStoredLog`, whose `publication` field binds current logical events to their matching publication operation. A query followed by Agent resume therefore reuses the same Decode and migration result. The in-flight map owns only running work; it is not a second completed-result cache.
+
+`SessionHandle.read()` reports whether its event values are detached or shared-frozen. The JSONL backend deep-freezes each decoded event graph once before memoization and creates the `shared-frozen` result there; later reads and slices preserve that producer-established state even when the slice is empty. `readColdSessionLog()` combines those values with locally owned interrupted-turn closers and passes the `eventState` through `SessionObservationReader`; `Session.fromRestore()` validates and adopts the seed without copying or freezing. Ordinary create and fork seeds keep their defensive snapshot path.
+
+Read-only restoration validates the event and settlement fields required by Session runtime behavior but does not expand every embedded Assistant stream. The publication Worker retains complete stream replay and checks content, usage, and replay-state agreement before a migrated successor is committed. Existing current-v2 files rely on their writer; consumers that expand a compact stream validate its records when they read it.
+
+### Read handle transition
+
+A read open adopts a handle with prepared events in `state.primed` while no current generation exists. Each later `read()` resolves the current path:
+
+```text
+if current generation is absent:
+  return slice of primed events
+else:
+  clear primed events
+  read current generation and enforce non-shrinking history
+```
+
+`resolveCurrentLog()` may therefore return `undefined` for an existing historical Session: it answers whether a current canonical file exists, not whether the Session can be read. Public `stat` and `list` continue to discover the historical header.
+
+### Write-open publication
+
+Write open acquires the process-local claim and kernel-backed cross-process lease before re-resolving the selected generation. If it remains historical, it obtains or reuses the prepared `StoredLog` and awaits `publish()`. Only then does it return a write handle primed with the prepared events.
+
+```text
+write open
+  → claim process-local ownership
+  → acquire SessionWriteLease
+  → re-resolve generation
+  → join or create preparation
+  → encode + sync temp
+  → Worker verify
+  → source identity check
+  → no-overwrite publish
+  → return writable handle
+```
+
+No external caller can append before the handle exists. `append`, `flush`, and `close` therefore retain their ordinary current-generation behavior and never need a “publishing” branch. Service `flush()` continues to flush only already adopted writers; it does not turn a read-only preparation into a write.
+
+### Follow and Agent promotion
+
+`session.follow` opens history through the read path, restores the Session and projections, emits the opening snapshot, and then starts Agent promotion. Agent resume uses write open, so it waits for publication before the Agent accepts a new turn. History visibility and write readiness are separate timing points without introducing an unpublished append state.
+
+## Problem-to-solution mapping
+
+| Serial-flow problem | Implemented mechanism | Guarantee |
+|---|---|---|
+| Read-only callers wait for encode and verify | Read open returns prepared events | First content waits only for Decode and migration |
+| Concurrent historical opens repeat work | Session/source-revision keyed single-flight | One migration per selected revision |
+| First caller owns shared cancellation | Caller-local `waitWithAbort()` plus backend controller | One cancellation does not kill other waiters |
+| Preparation is lost between query and resume | `PreparedStoredLog.publication` in bounded memo | Write open reuses the same artifact |
+| No current path exists for a read handle | Primed in-memory read | Historical data is readable before publication |
+| Read handle must observe later append | Re-resolve and switch from primed data to current file | Existing handles converge after publication |
+| Append before verification is unsafe | Publish inside write open before returning the handle | Returned writer is immediately durable-ready |
+| Automatic background publication has no owner | Only write open invokes `publish()` | No orphan write task from read-only access |
+| Source changes after readers saw the artifact | Fail publication without rerunning migration | Exposed logical history is never silently replaced |
+
+## Verification
+
+The benchmark uses the same 116,228,655-byte v0 Zstandard Session as the Stage decision. The first table compares every relevant implementation; the detailed scheduling comparison then holds the Codec/Stage chain constant between #3585 and preparation-first scheduling.
+
+### First opening of historical data
+
+| Implementation | Session restored | CPU | Peak RSS | Retained heap | Result |
+|---|---:|---:|---:|---:|---|
+| Original high-performance v0 reader | 4.594s | 6.048s | 2.720GB | 2.016GB | Reads about 9.14 million v0 events without migration |
+| Master whole-artifact v0-to-v2 migration | >72.8s | — | Decode stage reached at least 7.219GB | — | OOM before returning a handle |
+| #3585 streaming migration with serial publication | 6.241s | 8.493s | 2.107GB | 477MB | Produces and publishes a 72,784-event v2 Session |
+| #3586 preparation-first scheduling | 2.954s | — | 1.026GB | 463MB | Produces the same v2 Session and defers publication until write open |
+
+Preparation-first restoration is 53% faster than #3585 and 36% faster than the original high-performance reader even though it also migrates the artifact to v2.
+
+### Scheduling observation points
+
+| User-visible point | Serial publication | Preparation-first | Change |
+|---|---:|---:|---:|
+| Read open plus Session restoration | 6.241s | 2.954s | -53% |
+| `session.follow` opening snapshot | 7.587s | 2.912s | -62% |
+| Agent receives writable Session | 6.246s | 5.161s | -17% |
+| Reopen an already-current v2 Session | 1.284s | 0.964s | -25% |
+| Follow opening-snapshot peak RSS | 2.353GB | 1.059GB | -55% |
+
+Preparation spends about 2.61 seconds in Decode and migration. Deferred publication takes about 2.56 seconds: 0.83 seconds for encode/write/sync, 1.72 seconds for strict Worker verification, and about 0.005 seconds for source check and atomic publication. A read-only request performs none of that publication work.
+
+The prepared artifact and Session restoration peak near 1.03 GB RSS. Preparation and Worker verification together peak near 2.19 GB because the parent retains the logical artifact while the Worker independently validates the physical generation.
+
+Tests cover shared-waiter cancellation, all-waiters cancellation, memo handoff, read-handle switching, source drift, winner collision, publication idempotence, write-open ordering, Worker failure, and the plain-Node bundled Worker entry.
+
+## Consequences
+
+Read-only body access does not publish a generation. The first writer pays publication once before append. A configured JSONL root must still be readable and structurally valid, but historical body migration itself does not require a successor write.
+
+The bounded memo retains one migrated event array to bridge read and write opens. This is intentional: avoiding that retained artifact would require a second Decode and migration or would prevent early read availability.
+
+Publication failure rejects Agent resume and other write opens but does not invalidate read results already delivered from the unchanged historical source. Source drift is terminal for that write attempt rather than a trigger to recompute hidden state.
+
+The backend still has a broader pre-existing lifecycle gap: dispose does not own every `create()` or `open()` operation that has not yet returned a handle. This decision does not add migration-specific tracking to `flush()` or solve that general pending-operation problem.
+
+## Alternatives considered
+
+- **Keep serial publication for every open** — is the simplest physical state model but adds about 2.2 seconds to read-only first content and requires writable storage.
+- **Publish automatically in the background after read** — needs backend task ownership, shutdown quiescence, error reporting, and writer joining even when no caller requested a write.
+- **Return a writer before verification** — requires append to an unpublished stage and creates an additional durability and failure state for accepted events.
+- **Give each caller an independent preparation** — repeats the dominant Decode and migration work and multiplies peak memory under concurrent list/follow/resume operations.
+- **Let the first caller's signal cancel shared work** — makes later callers depend on unrelated cancellation timing.
+- **Rerun migration after source drift** — can replace history already shown to readers and makes one logical operation process the same large file more than once.
+- **Always keep read handles on primed memory** — prevents an existing handle from seeing later append and diverges from ordinary persistence refresh behavior.

+

+- Historical read open 仍会创建并 sync 临时 v2 generation、启动完整 verification Worker、复查 source、发布 v2 并重新打开 target。
+- Migration 在 encode 前已经得到完整 current artifact，但串行 API 只返回 committed physical snapshot。Persistence 必须再次 Decode current bytes 才能重建相同逻辑事件。
+- `session.follow` 必须等 publication 完成后才能发出 opening snapshot，而 Agent resume 才是第一个真正要求 append 权限的操作。
+- Read-only storage 无法提供逻辑上有效的历史 Session，因为 read open 强制发布 generation。
+
+### 直接拆分会破坏 lifecycle 保证
+
+- Verify 前返回 write handle 会让 append 写入 unpublished temporary file，并为已接纳事件引入第二种 durability state。
+- 每次 read 后自动启动 publication，需要 backend 负责 task failure、shutdown、cleanup，以及后续 writer 加入一个自己没有请求的任务。
+- Shared preparation 不能继承第一个 caller 的 AbortSignal；一个 reader 取消不能终止其他 waiter 仍依赖的工作。
+- Read handle 必须先提供 prepared memory，并在其他 caller 发布后切换到 current file 与其 append tail。
+- Reader 已经观察一个 prepared artifact 后，source drift 不能悄悄重跑 migration 并替换成另一份逻辑历史。
+
+## 决策
+
+JSONL backend 将 logical preparation 与 durable publication 分开。Read open 只等待 preparation；write open 复用 matching preparation，并在返回 writable handle 前等待 publication。
+
+### Prepared generation API
+
+```text
+interface PreparedJsonlMigration {
+  readonly sourceIdentity: JsonlPhysicalIdentity
+  readonly artifact: SessionFormatArtifact
+  publish(): Promise<JsonlPhysicalIdentity>
+}
+```
+
+`prepareJsonlMigration()` 读取一个稳定 historical revision，只执行一次完整 Stage chain，并在不 encode、不写文件的情况下返回 current artifact。`publish()` 是幂等操作：并发与后续调用共享同一个终态 Promise（包括拒绝结果），不会对同一 prepared artifact 重复 encode。
+
+`publish()` 把 current records 流式写入同目录排他创建的 temporary file，执行 sync，等待 bounded Worker verifier，比较 preparation 捕获的 source identity，再通过 no-overwrite 操作发布 canonical path。成功 publisher 复用 prepared logical artifact，不重新 Decode 自己的 target。竞争失败者只验证 winner 以精确 staged migration prefix 开头；append tail validation 仍属于 current reader。
+
+Publication 调用后会运行到 settlement，不会被 write caller 中途取消。Write open 会在 publication 前后检查 caller signal，因此取消可能在后继已经提交后拒绝 open，但不会泄漏 write lease。Source identity 变化会抛出 `JsonlGenerationSourceChangedError`、删除临时文件，并且不会重复 Decode 或 migration。
+
+### Preparation ownership 与取消
+
+Persistence backend 按 Session id、selected source path 与 stat-derived revision 保存一个 in-flight entry：
+
+```text
+interface MigrationPreparation {
+  sourcePath: string
+  sourceRevision: SessionPersistenceRevision
+  controller: AbortController
+  promise: Promise<PreparedStoredLog>
+  settled: boolean
+  waiters: number
+}
+```
+
+新的 read/write open 只有在 source path 与 revision 仍匹配时才加入已有 entry。`waitWithAbort()` 让每个 caller 的 AbortSignal 与 shared Promise 竞争，但不会把 caller signal 传给共享工作。只有最后一个 waiter 在 preparation 仍运行时离开，backend-owned controller 才会 abort。
+
+完成结果进入既有 bounded `coldLogMemo`。`StoredLog` 判别字段把已发布 current state 与 `PreparedStoredLog` 分开，后者的 `publication` 字段把 current logical events 与匹配的 publication operation 绑定，使 query 后紧接的 Agent resume 复用同一次 Decode 与 migration。In-flight map 只拥有运行中的工作，不是第二个 completed-result cache。
+
+`SessionHandle.read()` 会报告 event value 是 detached 还是 shared-frozen。JSONL backend 在 memo 化前只对每个已解码 event graph 深度冻结一次，并在该处构造 `shared-frozen` 结果；后续读取和 slice 即使为空也会保留生产者建立的状态。`readColdSessionLog()` 将这些 event 与本地独占的 interrupted-turn closer 组合，并通过 `SessionObservationReader` 继续传递 `eventState`；`Session.fromRestore()` 只校验和接管 seed，不再复制或冻结。普通 create 与 fork seed 继续使用 defensive snapshot 路径。
+
+Read-only restoration 会校验 Session runtime 直接依赖的 event 与 settlement 字段，但不会展开每一段嵌入式 Assistant stream。Publication Worker 继续执行完整 stream replay，并在提交 migrated successor 前校验 content、usage 与 replay state 一致性。已有 current-v2 文件信任其 writer；需要展开 compact stream 的 consumer 会在读取时校验 record。
+
+### Read handle 切换
+
+Current generation 不存在时，read open 会采用在 `state.primed` 中保存 prepared events 的 handle。后续每次 `read()` 都重新解析 current path：
+
+```text
+if current generation is absent:
+  return slice of primed events
+else:
+  clear primed events
+  read current generation and enforce non-shrinking history
+```
+
+因此，一个已有 historical Session 也可能让 `resolveCurrentLog()` 返回 `undefined`：它回答的是 current canonical file 是否存在，而不是 Session 是否可读。公开 `stat` 与 `list` 继续发现 historical header。
+
+### Write-open publication
+
+Write open 先取得进程内 claim 与内核支持的跨进程 lease，再重新解析 selected generation。如果它仍是 historical，就取得或复用 prepared `StoredLog` 并等待 `publish()`。之后才返回以 prepared events 为 primed state 的 write handle。
+
+```text
+write open
+  → claim process-local ownership
+  → acquire SessionWriteLease
+  → re-resolve generation
+  → join or create preparation
+  → encode + sync temp
+  → Worker verify
+  → source identity check
+  → no-overwrite publish
+  → return writable handle
+```
+
+Handle 返回前，外部 caller 无法 append。因此 `append`、`flush` 与 `close` 保持普通 current-generation 行为，不需要“publishing”分支。Service `flush()` 继续只 flush 已经 adopt 的 writer；它不会把 read-only preparation 转成 write。
+
+### Follow 与 Agent promotion
+
+`session.follow` 通过 read path 打开历史、恢复 Session 与 projections、发出 opening snapshot，然后启动 Agent promotion。Agent resume 使用 write open，因此会在 Agent 接收新一轮对话前等待 publication。历史可见与写入就绪成为两个明确时间点，同时不引入 unpublished append state。
+
+## 问题与方案对照
+

+|---|---|---|
+| Read-only caller 等待 encode 与 verify | Read open 返回 prepared events | 首屏只等待 Decode + migration |
+| 并发 historical open 重复工作 | Session/source-revision keyed single-flight | 每个 selected revision 只迁移一次 |
+| 第一个 caller 拥有共享取消 | Caller-local `waitWithAbort()` + backend controller | 单个取消不终止其他 waiter |
+| Query 与 resume 之间丢失 preparation | Bounded memo 中的 `PreparedStoredLog.publication` | Write open 复用相同 artifact |
+| Read handle 没有 current path | Primed in-memory read | Publication 前 historical data 可读 |
+| Read handle 需要观察后续 append | 重新 resolve，并从 primed data 切到 current file | Publication 后已有 handle 收敛 |
+| Verify 前 append 不安全 | Write open 返回前完成 publication | 返回 writer 立即具备普通 durability |

+
+## 验证
+
+Benchmark 使用 Stage 决策中的同一份 116,228,655-byte v0 Zstandard Session。第一张表比较 migration 工作涉及的全部实现；后续调度明细则保持 #3585 与 preparation-first 使用同一条 Codec/Stage chain，仅改变 persistence 调度。
+
+### 用户首次打开历史数据
+
+| 实现 | Session restore | CPU | Peak RSS | Retained heap | 结果 |
+|---|---:|---:|---:|---:|---|
+| 原高性能 v0 reader | 4.594s | 6.048s | 2.720GB | 2.016GB | 不迁移，读取约 914 万个 v0 event |
+| Master whole-artifact v0-to-v2 migration | >72.8s | — | Decode 阶段达到至少 7.219GB | — | 返回 handle 前 OOM |
+| #3585 streaming migration + 串行 publication | 6.241s | 8.493s | 2.107GB | 477MB | 生成并发布包含 72,784 个 event 的 v2 Session |
+| #3586 preparation-first 调度 | 2.954s | — | 1.026GB | 463MB | 生成相同 v2 Session，并把 publication 延迟到 write open |
+
+Preparation-first restore 比 #3585 快 53%，也比原高性能 reader 快 36%，同时仍然完成 artifact 到 v2 的 migration。
+
+### 调度观测点
+
+| 用户观测点 | 串行 publication | Preparation-first | 变化 |
+|---|---:|---:|---:|
+| Read open + Session restore | 6.241s | 2.954s | -53% |
+| `session.follow` opening snapshot | 7.587s | 2.912s | -62% |
+| Agent 得到 writable Session | 6.246s | 5.161s | -17% |
+| 已是 current v2 的再次打开 | 1.284s | 0.964s | -25% |
+| Follow opening-snapshot peak RSS | 2.353GB | 1.059GB | -55% |
+
+Preparation 中约 2.61 秒用于 Decode 与 migration。延后的 publication 约为 2.56 秒：encode/write/sync 0.83 秒、严格 Worker verification 1.72 秒、source check 与 atomic publication 约 0.005 秒。Read-only 请求完全不执行这段 publication。
+
+Prepared artifact 与 Session restore 的 peak RSS 约为 1.03 GB。Preparation 与 Worker verification 同时存在时峰值约 2.19 GB，因为 parent 保留 logical artifact，而 Worker 独立校验 physical generation。
+
+测试覆盖 shared-waiter cancellation、all-waiter cancellation、memo handoff、read-handle switching、source drift、winner collision、publication idempotence、write-open ordering、Worker failure 与 plain-Node bundled Worker entry。
+
+## 后果
+
+Read-only body access 不发布 generation。第一个 writer 会在 append 前支付一次 publication。已配置的 JSONL root 仍必须可读且结构有效，但 historical body migration 本身不要求写 successor。
+
+Bounded memo 会保留一份 migrated event array，用于连接 read 与 write open。这是有意的取舍：不保留该 artifact 就必须重复 Decode 与 migration，或者无法提前提供 read。
+
+Publication failure 会拒绝 Agent resume 和其他 write open，但不会使已经从 unchanged historical source 交付的 read result 失效。Source drift 对该 write attempt 是 terminal failure，不会触发 hidden state 重算。
+
+Backend 仍存在一个更广泛的既有 lifecycle 缺口：dispose 不拥有每个尚未返回 handle 的 `create()` 或 `open()` operation。本决策不会向 `flush()` 增加 migration-specific tracking，也不解决通用 pending-operation 问题。
+
+## 考虑过的替代方案
+
+- **每个 open 都保持串行 publication**——physical state 最简单，但让 read-only 首屏多等待约 2.2 秒并要求存储可写。
+- **Read 后自动后台 publish**——需要 backend task ownership、shutdown quiescence、error reporting，以及 writer 加入一个没有 caller 请求的任务。
+- **Verify 前返回 writer**——要求 append 写入 unpublished stage，并为已接纳事件增加一种 durability 与 failure state。
+- **每个 caller 独立 preparation**——重复最重的 Decode 与 migration，并在 list/follow/resume 并发时放大峰值内存。
+- **让第一个 caller signal 取消共享工作**——使后续 caller 依赖无关的 cancellation timing。
+- **Source drift 后重跑 migration**——可能替换已经展示给 reader 的历史，也会让一次逻辑 operation 重复处理同一大文件。
+- **Read handle 永远停留在 primed memory**——无法观察后续 append，并偏离普通 persistence refresh 行为。

 ## Format refusal — logs a build cannot faithfully read
 
-A backend refuses a log it cannot faithfully interpret with `SessionFormatUnsupportedError`, distinct from `SessionPersistenceCorruptionError` because nothing is damaged. `stat` and `list` classify the highest canonical generation and translate a supported historical header without reading or mutating its body. `open` runs the build-static adjacent migration chain under per-id serialization before returning a handle, leaves every source path, byte, and inode unchanged, and exclusively publishes only the final current generation. A future highest generation refuses even when an older readable generation remains. Current v2 restoration retains installed extensions and unknown events carrying `ignorable: true`; historical v0/v1 migration refuses an unknown type even when marked ignorable. The message appends the selected raw log path when the backend keeps one artifact per session. The JSONL backend migrates released v0 or v1 to current v2 and refuses a future version before interpreting its version-specific fields or event rows. An out-of-tree backend must enforce equivalent current-only handle values and direction-aware refusals at its physical-format entry. The [released-format migration decision](../../.agents/notes/implemented/architecture/2026-08-31-released-session-format-migrations.md) owns the chain and immutable-publication rules.

 The migration refuses a reference to a consumed chunk instead of redirecting it to a different semantic event. It remaps declared event provenance, surface replacements, command source events, compaction ranges and lists, and title message lists. The already model-visible `session/title-llm-request.messages` text remains byte-identical after source validation, so target validation does not reinterpret the old sequence numbers embedded in that prompt. A seeded source also refuses an inherited cut that splits an Assistant attempt; the target marks the exact cut with `session/end-seed { inherited: true }`.
 
-The v2 physical header requires `isSeeded` and does not store a numeric cut. The codec derives the cut from the last inherited end-seed marker, writes one event per row, range-encodes only `sourceEventSeqs`, and remains neutral to ordinary event vocabulary and payload growth. Released-current restoration admits event types known to the installed Session package plus unknown events carrying `ignorable: true`, and validates event members and relationships. Full current restoration additionally delegates payload and embedded-stream semantics to the installed Session package. The frozen exact writer-image validator lives under `src/testing` for edge fixtures.
+The v2 physical header requires `isSeeded` and does not store a numeric cut. The codec derives the cut from the last inherited end-seed marker, writes one event per row, range-encodes only `sourceEventSeqs`, and remains neutral to ordinary event vocabulary and payload growth. Released-current restoration admits event types known to the installed Session package plus unknown events carrying `ignorable: true`, and validates event members and relationships. Ordinary Session restoration checks runtime-required settlement fields without replaying embedded streams; persistence publication and the frozen writer-image fixture validator retain full stream verification.

 ### Reading the logs
 
-`open(id, 'read'|'write')` selects the highest canonical generation. Current input follows the ordinary fast path. Before either kind of handle returns for historical input, the backend decodes and migrates the source once, encodes a same-directory temporary file in bounded chunks, verifies it in a Worker Thread, rechecks the source revision, publishes the current successor without overwrite, and verifies and reopens the committed generation. The source remains byte-identical. The handle's `read(offset?, length?)` serves validated contiguous slices under the durability rules above. A write open primes the handle with the validated stored prefix, and a bounded revision-keyed memo lets an immediate observe-to-resume handoff reuse that parse. `stat(id)` and `list()` select and translate only the highest generation header without reading event rows or starting migration; snapshots carry `sizeBytes` and a best-effort stat-derived revision for the selected file. With `compression: 'none'`, the log is newline-delimited text an external reader can consume directly; the compressed default must be read through the backend.
+`open(id, 'read'|'write')` selects the highest canonical generation. Current input follows the ordinary fast path. For historical input, a read open decodes and migrates the source once, validates the current logical result, and returns it without publishing a successor. A write open reuses that revision-keyed preparation when available, or performs the same preparation, then encodes a same-directory temporary file in bounded chunks, verifies it in a Worker Thread, rechecks the source revision, and publishes the current successor without overwrite before returning. The source remains byte-identical. Source drift after preparation rejects that write open without replacing the logical history already returned to readers; a later write open prepares the new revision. The backend marks decoded event graphs `shared-frozen` when it freezes them before memoization; handle reads and slices preserve that state, including empty slices. Only an unmaterialized pending log reports `detached`. `stat(id)` and `list()` select and translate only the highest generation header without reading event rows or starting migration; snapshots carry `sizeBytes` and a best-effort stat-derived revision for the selected file.

 ### Design concept
 
-The backend owns its complete storage runtime (`src/storage.ts`): `JsonlSessionHandle` carries the per-handle mutation chain, the routed live-event buffer with its fixed batching window and single-flight drain, monotonic reads, and idempotent close; a tracker holds the in-process single-writer claims, the open-handle set teardown sweeps, and the created-but-unmaterialized pending sessions the backend's own session listeners route into. Historical body reads run the same serial ensure-current operation before constructing a handle. The package deliberately exposes only its default plugin export plus configuration types — the concrete class is not a named export, so consumers couple to `ctx.sessionPersistence`, and the shared seam suites (`runPersistenceContract`/`runLiveWritePathContract`) pin its observable behavior. Its change token is a best-effort file revision: device, inode, size, and nanosecond timestamps identify one log for `stat`/`list`, for the stable-read loop that retries a read torn by a concurrent append, and for the pre-publication source check.

+# Agent Note: Model-relative session-reference budgets

+Status: implemented

+
+## Problem
+
+A fixed 64 KiB reference budget discards useful source context on large-context models. The target session header describes a prior request, while agent options seed routing; neither necessarily identifies the model selected for the entering step.
+
+## Decision
+
+[Session-reference](../../../../packages/context/session-reference/README.md) observes the completed `system-prompt/assemble` waterfall with a local prepend listener and stores its provider/model pair in a WeakMap keyed by Agent. Preparation resolves that route through the optional LLM service; direct preparation before any assembly uses agent options. Diagnostics without an Agent do not update the map.
+
+Each source receives `max(65536, floor(contextWindow × 4 × referenceContextFraction))` bytes, with a default fraction of `0.2`. Four bytes per token is a sizing heuristic. Explicit `maxReferenceBytes` bypasses model lookup and remains exact. Missing route, service, or capacity retains the floor; lookup failures and cancellation propagate.
+
+## Alternatives considered
+
+**Read the header or options for every step.** Either can select a stale model after a live switch. The completed assembly exposes the route captured by model selection.
+
+**Reassemble or redispatch request routing during pre-step.** These operations repeat plugin effects and can capture a different selection. A local observer needs neither loop changes nor another public routing API.
+
+## Consequences
+
+The budget grows with model capacity without changing projection, retention, or preview policy. It remains per source, not an aggregate token reservation. The listener is effect-owned and disposable; the map does not retain agents. Focused tests cover the floor, fractional conversion, explicit overrides, live selection, absent metadata, cancellation, lookup errors, and listener removal.

+# Agent Note: 模型相对会话引用预算

+[English](2026-09-05-session-reference-model-budget.md) | 中文
+
+## Problem
+
+固定的 64 KiB 引用预算会在大上下文模型上丢弃有用的来源上下文。目标会话头描述上一次请求，而 agent options 为路由提供初始值；两者都不一定标识当前进入步骤所选的模型。
+
+## Decision
+
+[Session-reference](../../../../packages/context/session-reference/README.zh.md) 通过本地 prepend 监听器观察已完成的 `system-prompt/assemble` 瀑布，并把 provider/model 对存入以 Agent 为键的 WeakMap。准备阶段通过可选 LLM 服务解析该路由；首次组装前直接准备则使用 agent options。不带 Agent 的诊断不会更新映射。
+
+每个来源获得 `max(65536, floor(contextWindow × 4 × referenceContextFraction))` 字节，默认比例为 `0.2`。每个 token 四字节是容量估算。显式 `maxReferenceBytes` 跳过模型查询并保持精确值。缺少路由、服务或容量时保留下限；查询失败和取消会传播。
+
+## Alternatives considered
+

 Preparation reads each referenced session's current surface exactly once, when the target message reaches `agent/pre-step`, so a queued message captures source state at model-step entry and the resulting context is immutable afterwards. Projection keeps only direct-user `user/message`, assistant text, and `user/message` checkpoints carrying the canonical compaction marker; separately sourced session-reference messages are excluded, preventing recursive snapshot propagation. Source text is serialized as JSON with every `<` escaped as `\u003c`, so it cannot spell the `<referenced-sessions>` framing tag.

 [Session-reference](../../../../packages/context/session-reference/README.md) observes the completed `system-prompt/assemble` waterfall with a local prepend listener and stores its provider/model pair in a WeakMap keyed by Agent. Preparation resolves that route through the optional LLM service; direct preparation before any assembly uses agent options. Diagnostics without an Agent do not update the map.

+# Agent Note: Reuse spill storage for truncated session references
+
+Status: implemented
+
+English | [中文](2026-09-05-session-reference-spill-reuse.zh.md)
+
+## Problem
+
+A bounded cross-session preview can omit whole messages or most of a retained message. A model that sees only the preview needs an accurate account of the omission and a way to inspect the captured text, without treating another session's instructions as current authority. Rereading the source later would not recover the same observation when the source advances or compacts.
+
+## Decision
+
+[Session-reference preparation](../../../../packages/context/session-reference/README.md) retains its existing preview policy and per-reference JSON byte budget. Each truncated reference attempts `saveText` through optional `ctx.get("spillStore")`; an untruncated reference writes no artifact. The full transcript and bounded preview derive from the same captured user/assistant text projection, including compaction checkpoints but excluding tools, reasoning, and other injected context. No second source read occurs.
+
+The artifact belongs to the target session receiving the context. Its descriptive source is `{ kind: "session-reference", sessionId, label }`, where `sessionId` identifies the referenced session. [Spill storage](../../../../packages/spill/spill/README.md) accepts this minimal alternative alongside the existing tool source; it requires no fabricated tool name or call id. Storage ownership does not authorize retrieval.
+
+A separate omission notice outside the bounded preview JSON records exact `omittedMessages` and `omittedBytes`. It carries the saved locator and backend `retrievalHint`, or an unavailable outcome distinguishing missing storage from a failed save. This notice is model-visible content in the same durable reference message, not metadata-only UI decoration. A tiny preview budget cannot remove it. The saved transcript carries capture metadata, including `capturedFormatVersion`, and the same untrusted-background warning as the preview. Per-message JSON string fragments contain at most 64 Unicode code points per line; decoding and concatenating them restores exact text, including original newlines. This fixed artifact format keeps long single-line middles retrievable with ordinary paged file reads without changing preview retention.
+
+Cancellation after an asynchronous save prevents context publication, even if storage already created the artifact. The consumer does not add rollback or deletion APIs; the existing backend expiry policy governs that artifact. Replay uses the logged preview and notice and never repeats the save or source read.
+
+## Alternatives considered
+
+**Write a separate session-reference file store.** Rejected because private naming, session-scoped ownership, locator guidance, and artifact lifetime already belong to spill storage. A second store would duplicate those policies.
+
+**Reread the source when saving or retrieving.** Rejected because source mutation could make the artifact disagree with the preview and its captured sequence. Saving the original projection preserves the observation.
+
+**Put omission and retrieval data inside the bounded preview JSON.** Rejected because that spends the conversation budget on metadata and can hide the notice precisely when the budget is smallest. Separate durable model-visible text preserves both obligations.
+
+**Use tool provenance for every spill.** Rejected because a session reference has no model-issued tool call. Invented tool ids would misattribute the artifact rather than describe its producer.
+
+## Consequences
+
+The model can inspect text omitted from a preview without increasing the preview budget. Notices add request tokens outside that budget, and retrieval adds the requested transcript text later. Storage is best-effort: an unavailable notice is honest about loss of retrieval while the bounded preview remains usable. A saved locator can expire even while its notice remains in durable history; this feature does not promise permanent archival or recover content already removed by source compaction.
+
+## Verification
+
+The [unit suite](../../../../packages/context/session-reference/tests/session-reference.spec.ts) pins omission counts, full Unicode and control-character recovery, whole-message drops, three-reference isolation, missing and failed storage, source exclusions and mutation isolation, and cancellation before publication. The [Loader composition test](../../../../packages/context/session-reference/tests/loader-composition.spec.ts) exercises the real local store and paged `read` tool against the middle of a giant single-line message, with target-session storage ownership. The [keyless recorded-session scenario](../../../../snapshots/session/session-reference-spill/snapshot.yml) pins the durable model-visible reference context. Replay [normalizes known quoted spill locators](../../../../packages/test-support/session-snapshot/README.md) while preserving saved byte lengths and omission counts.
+
+## Related decisions
+
+The [tool-output spill decision](../architecture/2026-07-08-tool-output-spill-files.md) remains active: its storage/policy separation, failure degradation, provider caps, and retrieval alternatives still constrain tool consumers. This note extends its producer vocabulary without replacing that rationale. [Separate context injection from turn execution](../architecture/2026-07-24-separate-context-injection-from-turn-execution.md) remains the authority for durable message admission, and [producer-declared context forms](../feature/2026-08-05-context-form-vocabulary.md) remains the authority for recall presentation.

+# Agent Note: 为截断的会话引用复用 spill 存储
+
+Status: implemented
+
+[English](2026-09-05-session-reference-spill-reuse.md) | 中文
+
+## 问题
+
+有界的跨会话预览可能省略整条消息，也可能省略保留消息中的大部分文本。只看到预览的模型需要准确了解省略情况，并能检查已捕获的文本，同时不能把其他会话的指令视为当前授权。源会话继续推进或发生压缩后，再次读取无法恢复同一次观察。
+
+## 决策
+
+[会话引用准备](../../../../packages/context/session-reference/README.zh.md)保留既有预览策略和逐引用 JSON 字节预算。每个被截断的引用通过可选的 `ctx.get("spillStore")` 尝试 `saveText`；未截断的引用不写入产物。完整转录与有界预览来自同一份已捕获的 user／assistant 文本投影，包含压缩检查点，但排除工具、推理与其他注入上下文。不发生第二次源读取。
+
+产物归接收上下文的目标会话所有。其描述性来源是 `{ kind: "session-reference", sessionId, label }`，其中 `sessionId` 标识被引用的会话。[spill 存储](../../../../packages/spill/spill/README.zh.md)在工具来源之外接受这一最小分支；不需要伪造工具名称或调用 id。存储归属不授权取回。
+
+有界预览 JSON 之外的独立省略通知记录精确的 `omittedMessages` 与 `omittedBytes`。通知携带保存后的定位信息和后端 `retrievalHint`，或区分未配置存储与保存失败的不可用结果。该通知是同一条持久引用消息中的模型可见内容，而不是只供 UI 使用的元数据装饰。极小的预览预算无法移除它。保存的转录携带包括 `capturedFormatVersion` 在内的捕获元数据，以及与预览相同的不受信任背景警告。每条消息的 JSON 字符串片段每行至多包含 64 个 Unicode 码点；解码并拼接后可恢复精确文本，包括原始换行。这种固定产物格式让普通分页文件读取可以取回很长的单行文本中部，而不改变预览保留策略。
+
+异步保存后的取消会阻止上下文发布，即使存储已经创建了产物。消费方不增加回滚或删除 API；该产物遵循后端既有过期策略。回放使用已记录的预览与通知，不会重复保存或源读取。
+
+## 考虑过的替代方案
+
+**另写一个会话引用文件存储。** 不予采纳，因为私有命名、会话级归属、定位指引与产物生命周期已经由 spill 存储负责。第二套存储会重复这些策略。
+
+**保存或取回时重新读取源。** 不予采纳，因为源变更可能使产物与预览及其捕获序列不一致。保存原始投影可以保留该次观察。
+
+**把省略与取回数据放入有界预览 JSON。** 不予采纳，因为这会让元数据占用对话预算，并可能在预算最小时恰好隐藏通知。独立的持久模型可见文本同时保留两项保证。
+
+**所有 spill 都使用工具来源。** 不予采纳，因为会话引用没有模型发出的工具调用。虚构工具 id 会错误归属产物，而不是描述其生产者。
+
+## 后果
+
+模型可以检查预览省略的文本，而无需增加预览预算。通知在该预算之外增加请求 token，之后的取回再添加所请求的转录文本。存储采用尽力而为策略：不可用通知如实说明无法取回，而有界预览仍可使用。即使通知仍在持久历史中，保存的定位信息也可能过期；此功能不承诺永久归档，也无法恢复源压缩已经移除的内容。
+
+## 验证
+
+[单元测试](../../../../packages/context/session-reference/tests/session-reference.spec.ts)锁定省略计数、完整 Unicode 与控制字符恢复、整条消息丢弃、三个引用的隔离、无存储与保存失败、来源排除与变更隔离，以及发布前取消。[Loader 组合测试](../../../../packages/context/session-reference/tests/loader-composition.spec.ts)使用真实本地存储和分页 `read` 工具，读取巨型单行消息的中部，并检查存储归目标会话所有。[无密钥录制会话场景](../../../../snapshots/session/session-reference-spill/snapshot.yml)锁定持久的模型可见引用上下文。回放会[规范化已知的带引号 spill 定位信息](../../../../packages/test-support/session-snapshot/README.zh.md)，同时保留保存字节数与省略计数。
+
+## 相关决策
+
+[工具输出 spill 决策](../architecture/2026-07-08-tool-output-spill-files.zh.md)保持活跃：其存储／策略分离、失败降级、提供方上限与取回替代方案仍约束工具消费方。本说明扩展其生产者词汇，而不替代这些理由。[分离上下文注入与轮次执行](../architecture/2026-07-24-separate-context-injection-from-turn-execution.zh.md)仍负责持久消息准入，[生产者声明的上下文形式](../feature/2026-08-05-context-form-vocabulary.zh.md)仍负责 recall 展示。

 ### What the agent gets
 
-A message that cites other sessions is followed immediately by a `## Referenced sessions` snapshot as a second user-role message. The snapshot is untrusted background: the fixed warning tells the model not to follow instructions, permission claims, or tool requests inside it unless the current user explicitly repeats them. Each source is bounded independently — at most `maxReferences` distinct sessions per message and a resolved byte budget per source — and a source that cannot fit its budget fails preparation instead of returning partial context.
+A message that cites other sessions is followed immediately by a `## Referenced sessions` snapshot as a second user-role message. The snapshot is untrusted background: the fixed warning tells the model not to follow instructions, permission claims, or tool requests inside it unless the current user explicitly repeats them. Each source preview is bounded independently — at most `maxReferences` distinct sessions per message and a configured or model-relative serialized JSON byte budget per source. Retention drops older non-checkpoint messages before shortening retained text; preparation fails only when the reference cannot fit even after retention.
+
+For a truncated reference, an optional spill backend saves the full captured text projection under the target session. A separate omission notice outside the bounded preview JSON gives exact `omittedMessages` and `omittedBytes`, then the saved locator and `retrievalHint`, or an unavailable outcome distinguishing missing storage from a failed save. The notice is part of the same durable context message. Full transcripts carry the same untrusted-background warning and capture metadata, including `capturedFormatVersion`. Each message uses JSON string fragments of at most 64 Unicode code points per line; decode and concatenate its fragments to recover exact text, including original newlines. This fixed storage format keeps even long single-line text readable through paged file reads.

 ### Design concept
 
-Preparation reads each referenced session's current surface exactly once, when the target message reaches `agent/pre-step`, so a queued message captures source state at model-step entry and the resulting context is immutable afterwards. Projection keeps only direct-user `user/message`, assistant text, and `user/message` checkpoints carrying the canonical compaction marker; separately sourced session-reference messages are excluded, preventing recursive snapshot propagation. Source text is serialized as JSON with every `<` escaped as `\u003c`, so it cannot spell the `<referenced-sessions>` framing tag.
+Preparation reads each referenced session's current surface exactly once, when the target message reaches `agent/pre-step`. Both preview and spill use that same captured projection: direct-user text, assistant text, and user checkpoints carrying the canonical compaction marker; tools, reasoning, and other injected context are excluded. This prevents recursive reference propagation and prevents a later source mutation from changing the saved transcript. Preview JSON escapes every `<` as `\u003c`, so source text cannot spell the `<referenced-sessions>` framing tag.
+
+The resolver discovers optional storage through `ctx.get("spillStore")` and saves only truncated references. Storage ownership is the target session; provenance identifies the referenced source session and label, without a fabricated tool call. Cancellation is checked after the asynchronous save and prevents publication even if an artifact was written. Artifact expiry remains the backend's existing policy.
 
 The budget uses the provider and model captured after `system-prompt/assemble` completes for the target agent. Direct `prepare` calls before any assembly use agent options; session headers do not select the budget model. Diagnostic assemblies without an agent do not affect captured routes.

 ## Summary
 
-The `spill/` group keeps oversized tool output out of the model's context without losing it: when a tool result exceeds a deployment's byte cap, the full text is saved to a spill artifact and the model sees a bounded preview plus a locator it can read or search later. The family splits into three packages — the storage service in `spill/`, the local filesystem backend in `spill-local/`, and the result policy in `spill-policy/` that decides when a final tool result is too large. Spilling is opt-in and best-effort: the policy acts only when `maxInlineBytes` is configured, and a storage failure leaves the original result visible. The group owns storage and result replacement only; preview mechanics live in `dsh-output-retention`, and provider resource caps remain separate.
+The `spill/` group stores full text outside the model's context and returns a locator with retrieval guidance. The family splits into the storage service in `spill/`, the local filesystem backend in `spill-local/`, and the tool-result policy in `spill-policy/`. Tool-result spilling is opt-in through `maxInlineBytes` and keeps the original result on storage failure. [Session references](../context/session-reference/README.md) also consume storage directly for truncated captured transcripts, with their own preview and failure notices; they do not require the tool-result policy.

Mount it whenever a composition needs spill storage on the same machine the agent runs on. Files are private to the current user, names are unpredictable, and each session's files group under a stable directory, so a shared root cannot leak output or be redirected by a planted symlink. Configuration selects the root and the startup-cleanup retention period; previews and spill decisions live in other packages.

Choose it when a deployment must keep oversized tool output retrievable without flooding the model's context. The service owns storage only: no retention policy, no tool-result replacement, and no retrieval or search API. A real storage failure rejects loudly, so the caller decides how to degrade.

 ## 使用本包
 
-需要 spill 工具输出的组合会挂载一个 spill 后端——仅本包本身不存储任何内容——并由 `dsh-spill-policy` 插件决定何时 spill。插件与工具作者直接调用 `ctx.spillStore.saveText()`，在当前会话下持久化文本。
+保存 spill 产物的组合需要挂载一个后端——仅本包本身不存储任何内容。`dsh-spill-policy` 决定工具结果何时 spill；`dsh-session-reference` 直接保存被截断引用的转录，不需要该策略。调用方使用 `ctx.spillStore.saveText()` 并明确指定归属；可选消费方通过 `ctx.get("spillStore")` 获取后端。
 
 ### 何时选择
 
-当部署需要在模型只看到有界预览之后仍可检索超大的工具输出时，选择 spill 存储——例如模型稍后可能想读取或搜索的抓取页面正文。当组合中没有工具会产生大到值得处理的输出，或部署没有模型工具可读取的本地文件系统时，你不需要本包；此时需要的是一个在该环境中定位信息有明确含义的后端。

 `normalizeSessionSnapshot` retains the complete Session header and event payloads but omits top-level `seq`/`time` envelopes from committed fixtures after normalizing paths and scrubbing request headers; it also normalizes embedded stream clocks and historical packed-row `seq0`/`time0` envelopes. Replay synthesizes the top-level envelopes in memory, while runtime persistence continues to write complete logs. Multi-session comparison restores every selected persisted or projected fixture through the current build-static Session format catalog before identity redaction and normalization, so retained v0/v1 replay input and fresh `session.v2.jsonl` writer output compare as one v2 logical Session without rewriting or renaming historical files. Expected and harvested logs use the same strict restoration path; source filenames cannot alter format validation. Versionless protocol-adapter unit fixtures remain outside the released Session format corpus. Current v2 fixtures use one row per event; retained v0/v1 fixtures may use canonical packed rows. The [temporary repository migrator](../../../scripts/migrate-packed-session-fixtures.ts) (`pnpm run migrate:packed-session-fixtures`) rewrites older historical layouts, and its [removal proposal](../../../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) owns its deletion.
 
+Known snapshot spill paths normalize to stable locator tokens, including paths quoted inside JSON omission notices. Normalization changes only the locator: saved byte lengths and omission counts remain comparison evidence.
+
 ### Record, replay, and refresh
 
 `pnpm run test:snapshot:record` calls the live LLM and writes the harvested current generation under its canonical versioned filename. Record and refresh never rename or delete a completed generation, including generations of a child role absent from a later run; reviewed source-tree curation removes a predecessor only after the same role has a verified current replacement. Scenarios with an explicit `sessionFormat` remain read-only in record mode. `pnpm run test:snapshot:refresh` stays keyless, runs the selected highest replay input, and writes stdout, owned prompt and tool-schema sidecars, and a fresh current-generation comparable Session output unless the manifest retains a historical generation. Each composition owner keeps its replay patch beside its live patch; top-level `snapshots/` owns Session-driven scenarios, while other expected outputs stay beside their owning package. [`dsh-llm-replay`](../llm-replay/README.md) serves the recorded streams selected through `DSH_SNAPSHOT_*` environment values.

 `normalizeSessionSnapshot` retains the complete Session header and event payloads but omits top-level `seq`/`time` envelopes from committed fixtures after normalizing paths and scrubbing request headers; it also normalizes embedded stream clocks and historical packed-row `seq0`/`time0` envelopes. Replay synthesizes the top-level envelopes in memory, while runtime persistence continues to write complete logs. Multi-session comparison restores every selected persisted or projected fixture through the current build-static Session format catalog before identity redaction and normalization, so retained v0/v1 replay input and fresh `session.v2.jsonl` writer output compare as one v2 logical Session without rewriting or renaming historical files. Expected and harvested logs use the same strict restoration path; source filenames cannot alter format validation. Versionless protocol-adapter unit fixtures remain outside the released Session format corpus. Current v2 fixtures use one row per event; retained v0/v1 fixtures may use canonical packed rows. The [temporary repository migrator](../../../scripts/migrate-packed-session-fixtures.ts) (`pnpm run migrate:packed-session-fixtures`) rewrites older historical layouts, and its [removal proposal](../../../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) owns its deletion.

Subject: [PATCH 51/70] perf(llm,host): read embedded Assistant streams per
 compact record

Session format v2 embeds each attempt's compact stream in
assistant/message and assistant/attempt, but Host and client consumers
still expanded it into per-member TimedStreamChunk arrays and did
per-member work; expandAssistantStream materializes the full array before
find/toReversed/break can answer. Session Stats (the projection phase of
every Session open), the token meter's usage and provider-assembly folds,
the subagent output fold, and the Session Controller image lookup still
paid O(members) allocation and time per settlement.

The Chat and Trajectory definitions were already settled from
message.content on master; the remaining per-member folds stay.

dsh-llm now exports record-level readers (first token, visible content,
visible text, last raw chunk of a type, raw chunks of a type, joined
text, run-aware assembly, per-run first-token/first-visible times) that
scan the compact records once with early exit. Session Stats reads
assistantStreamFirstTokenTime, the token meter reads
lastAssistantStreamChunk(stream, 'usage') and assembles through
assembleAssistantStream, the subagent output fold appends
joinAssistantStreamText, and the Session Controller scans
assistantStreamChunks(stream, 'block-end').

expandAssistantStream is deliberately not memoized: retaining expansions
costs roughly ten times the compact stream for the Session's lifetime.
It remains the validating path at durable boundaries.

Synthetic 200-turn v0 migration benchmark, median of five: first-open
projection 28.0 ms -> 5.4 ms, first-open total 76.9 -> 50.0 ms, peak RSS
137.2 -> 94.9 MB; reopen projection 17.8 -> 5.6 ms; all phase budgets and
the 128 MB heap constraint keep passing.

+# Agent Note: Embedded Assistant stream consumers read compact records
+
+Status: implemented
+
+English | [中文](2026-09-06-embedded-stream-record-readers.zh.md)
+
+## Problem
+
+Session format v2 embeds each model attempt's compact stream (`AssistantStreamRecord[]`: packed `text-chunks`, `reasoning-chunks`, and `tool-call-chunks` runs plus timestamped raw `chunk` records) in `assistant/message` and `assistant/attempt`. Consumers that folded those settlements called `expandAssistantStream()` first; it materializes the complete per-member array, so a consumer that needs one fact (`find` on the first token, the last usage chunk, a joined text, one block-end) paid O(members) allocation and time: about two objects per member on top of the compact form.
+
+After v2 embedded streams settlement widened with the message content and Chat and Trajectory sections settled directly from it, the remaining expand consumers are the Host and client folds: Session Stats reads the first-token time per `assistant/attempt` and `assistant/message` (the projection phase of every Session open), the token meter rebuilds provider content and scans every stream for its last usage chunk (the projection unit still scans to the end), the subagent output fold joins plain text, and the Session Controller image lookup scans for block-end chunks.
+
+## Decision
+
+`@deepseek-ai/dsh-llm` answers consumer questions directly from compact records; every remaining consumer folds records once with early exit.
+
+`packages/llm/llm/src/assistant-stream.ts` exports record-level readers beside the accumulator and `expandAssistantStream`:
+
+- Chunk rules: `isTokenDelta` (non-empty text, reasoning, or Tool-call arguments fragment, or any name-bearing Tool-call delta), `isVisibleChunk` (non-whitespace text or reasoning, or a block start or end of any kind other than text, reasoning, or Tool call), and `chunkHasVisibleText` (non-whitespace text delta or completed text block).
+- Run readers: `runFirstTokenTime` and `runFirstVisibleTime` reconstruct the first qualifying member's time from `time0` and the `dt` gaps and stop scanning there; a name-bearing Tool-call run yields `time0` without reading a fragment.
+- Stream readers: `assistantStreamFirstTokenTime`, `assistantStreamHasVisibleContent`, `assistantStreamHasVisibleText`, `lastAssistantStreamChunk(stream, type)` (backward scan), `assistantStreamChunks(stream, type)`, `joinAssistantStreamText`, and `assembleAssistantStream`, which feeds a `BlockAssembler` one joined delta per run (assembly only concatenates, so blocks, usage, finish, and replay state equal the per-member result). `RawStreamChunkType` excludes the delta types, so a raw-chunk lookup can never silently skip packed members.
+
+Session Stats reads `assistantStreamFirstTokenTime`; the token meter reads `lastAssistantStreamChunk(stream, 'usage')` and assembles provider output through `assembleAssistantStream`; the subagent output fold appends `joinAssistantStreamText`; the Session Controller scans `assistantStreamChunks(stream, 'block-end')` for images.
+
+`expandAssistantStream` keeps its strict validation and its remaining callers, which need every member or validate the stream at a durable boundary: Session restore validation, the v1-to-v2 migration validator and publication Worker replay, the reconnect baseline, and test support.
+
+### Measurements
+
+The repo's synthetic first-open benchmark (200 turns, 127,400 released-v0 events, 500,000 streamed deltas in 1,600 compact records; five samples, median):
+
+| Phase | Before | After |
+|---|---|---|
+| first-open projection | 28.0 ms | 5.9 ms |
+| first-open total | 76.9 ms | 53.8 ms |
+| first-open peak RSS | 137.2 MB | 94.6 MB |
+| reopen projection | 17.8 ms | 6.5 ms |
+
+Open, read, and restore phases are unchanged; the reader keeps the same first-token time by construction (the first qualifying member is the first record's first qualifying fragment, and the deltas stay ordered).
+
+## Alternatives considered
+
+**Memoize `expandAssistantStream` per input array.** Expanding all streams once costs tens of milliseconds, but retaining the expansions costs about ten times the compact stream for the event's lifetime — a permanent version of the transient allocation the change removes. The readers remove the need for retained expansions entirely.
+
+**Keep the per-member fold.** Early-exit `.find` still materializes the whole array first, so the allocation and O(members) time remain.
+
+## Consequences
+
+Host and Client folds of an embedded settlement cost O(records) plus one join per run, and no consumer materializes members unless it validates at a durable boundary or needs every member. The token, visibility, and visible-text rules have one home in `dsh-llm`, so a record reader and the accumulator's packing rules cannot drift apart.
+
+Publication verification (`assertCurrentAssistantStreams`) still replays every settlement at publish time; because it must prove content-by-chunk agreement, converting it to run-aware assembly without member materialization remains open work.

+# Agent Note: 内嵌 Assistant 流的消费方直接读取紧凑记录
+
+Status: implemented
+
+[English](2026-09-06-embedded-stream-record-readers.md) | 中文
+
+## 问题
+
+Session 格式 v2 将每次模型尝试的紧凑流（`AssistantStreamRecord[]`：打包的 `text-chunks`、`reasoning-chunks`、`tool-call-chunks` run 加上带时间戳的原始 `chunk` 记录）嵌入 `assistant/message` 与 `assistant/attempt`。折叠这些 settlement 的消费方会先调用 `expandAssistantStream()`；它会物化完整的逐成员数组，因此只需一个事实的消费方（find 首个 token、最后一个 usage chunk、拼接文本、一个 block-end）也要付出 O(members) 的分配与时间：在紧凑形式之上每个成员约两个对象。
+
+在 v2 内嵌流 settlement 随消息内容扩展、Chat 与 Trajectory 区块直接由内容结算之后，剩余的 expand 消费方是 Host 与客户端折叠：Session Stats 读取每个 `assistant/attempt` 与 `assistant/message` 的首 token 时间（每次打开 Session 的 projection 阶段）、token 计量重建提供商内容并扫描每个流到最后一个 usage chunk（projection 单元仍扫描到末尾）、子代理输出折叠拼接纯文本、Session Controller 镜像查找扫描 block-end chunk。
+
+## 决策
+
+`@deepseek-ai/dsh-llm` 直接从紧凑记录回答消费方问题；剩余消费方对记录做一次带提前退出的折叠。
+
+`packages/llm/llm/src/assistant-stream.ts` 在累加器与 `expandAssistantStream` 之外导出记录级读取器：
+
+- Chunk 规则：`isTokenDelta`（非空文本、reasoning 或 Tool-call 参数片段，或任何带名称的 Tool-call delta）、`isVisibleChunk`（非空白文本或 reasoning，或 text/reasoning/Tool call 之外的任意块开始或结束）、`chunkHasVisibleText`（非空白文本 delta 或完成的文本块）。
+- Run 读取器：`runFirstTokenTime` 与 `runFirstVisibleTime` 从 `time0` 与 `dt` 间隔重建首个合格成员的时间并停止扫描；带名称的 Tool-call run 直接产出 `time0`，不读片段。
+- 流读取器：`assistantStreamFirstTokenTime`、`assistantStreamHasVisibleContent`、`assistantStreamHasVisibleText`、`lastAssistantStreamChunk(stream, type)`（逆向扫描）、`assistantStreamChunks(stream, type)`、`joinAssistantStreamText` 与 `assembleAssistantStream`（每个 run 向 `BlockAssembler` 喂入一个拼接后的 delta；组装只做拼接，因此 blocks、usage、finish 与 replay state 与逐成员结果一致）。`RawStreamChunkType` 排除 delta 类型，因此原始 chunk 查找不可能静默跳过打包成员。
+
+Session Stats 读取 `assistantStreamFirstTokenTime`；token 计量读取 `lastAssistantStreamChunk(stream, 'usage')` 并通过 `assembleAssistantStream` 组装提供商输出；子代理输出折叠追加 `joinAssistantStreamText`；Session Controller 用 `assistantStreamChunks(stream, 'block-end')` 扫描镜像。
+
+`expandAssistantStream` 保留其严格校验与其余调用方（需要每个成员或在持久边界校验流）：Session 恢复校验、v1-to-v2 迁移校验器与发布 Worker 重放、重连基线、测试支撑。
+
+### 测量
+
+仓库的合成 first-open 基准（200 循环、127,400 个 released-v0 事件、1,600 条紧凑记录中的 500,000 个流式 delta；五次采样取中位数）：
+
+| 阶段 | 之前 | 之后 |
+|---|---|---|
+| first-open projection | 28.0 ms | 5.9 ms |
+| first-open 总计 | 76.9 ms | 53.8 ms |
+| first-open 峰值 RSS | 137.2 MB | 94.6 MB |
+| reopen projection | 17.8 ms | 6.5 ms |
+
+Open、read、restore 阶段不变；读取器按构造保持相同的首 token 时间（首个合格成员即首条记录的首个合格片段，且 delta 保持有序）。
+
+## 备选方案
+
+**按输入数组记忆化 `expandAssistantStream`。** 展开全部流只需几十毫秒，但保留展开结果在事件生命周期内约花费紧凑流的十倍内存——这是本变更移除的瞬时分配的永久版本。读取器完全消除了对保留展开的需求。
+
+**保留逐成员折叠。** 提前退出的 `.find` 仍然先物化整个数组，因此分配与 O(members) 时间仍在。
+
+## 后果
+
+Host 与客户端折叠一次内嵌结算的代价为 O(records) 加每个 run 一次拼接，且除非在持久边界校验或需要每个成员，消费方不再物化成员。token、可见性与可见文本规则在 `dsh-llm` 中只有一处，因此记录读取器与累加器的打包规则不可能漂移。
+
+发布校验（`assertCurrentAssistantStreams`）仍在发布时重放每个 settlement；因为它必须按 chunk 证明内容一致，将其转为不入成员的 run 感知组装仍是未完成工作。

 - **Expose and activate providers through configuration** — adapters declare configurable-provider routes plus a settings namespace, so configuration surfaces can activate dormant providers and edit connection facts without a restart.
 - **Discover and resolve models** — list the models an adapter advertises, interrogate an endpoint for the models it serves, and resolve one exact model's context window, output default, reasoning efforts, and input modalities.
 - **Validate call config** — an explicit or configured reasoning effort is checked against the exact model before any provider I/O, and an adapter-configured output cap is materialized when the request omits one.
+- **Read an embedded Assistant stream without expanding it** — `assistantStreamFirstTokenTime`, `assistantStreamHasVisibleContent`, `assistantStreamHasVisibleText`, `lastAssistantStreamChunk`, `assistantStreamChunks`, `joinAssistantStreamText`, and `assembleAssistantStream` answer their questions from the compact records in one pass that stops at the first qualifying member; `runFirstTokenTime` and `runFirstVisibleTime` do the same for one packed run, and `isTokenDelta`, `isVisibleChunk`, and `chunkHasVisibleText` define the token and visibility rules for a single chunk. `expandAssistantStream` remains the validating path for records read at a durable boundary; it is not memoized, because a retained expansion costs roughly ten times the compact stream for as long as the event lives.

Subject: [PATCH 52/70] docs(llm): scope the record readers' early-exit claims;
 state that readers trust the static record type

Reflect the review feedback on the reader list: assistantStreamFirstTokenTime and the has-visible readers stop at the first qualifying member, while lastAssistantStreamChunk, assistantStreamChunks, and joinAssistantStreamText scan the whole stream; assembleAssistantStream feeds a BlockAssembler one joined delta per run. Record-level readers trust the static record type; expandAssistantStream is the validating path.

+# Agent Note: trusted release rehearsals on persistent Linux runners
+
+Status: implemented
+
+English | [中文](2026-09-06-release-rehearsal-selfhosted.zh.md)
+
+## Problem
+
+Dependency-layout and release-pack rehearsals consume hosted Linux minutes without requiring npm or API credentials. Moving arbitrary pull-request code or credentialed publication onto a persistent shared host would weaken isolation; reusing a checkout without cleaning would also weaken the packed-payload proof.
+
+## Decision
+
+The two jobs in [release.yml](../../../../.github/workflows/release.yml) and the pack job in [release-vendor.yml](../../../../.github/workflows/release-vendor.yml) select the existing self-hosted Linux pool only with the writer-controlled `DSH_CI_FAILOVER_LINUX` repository variable set to `selfhosted`. The selector requires the canonical repository and a non-Dependabot actor, then admits only master pushes or same-repository, non-fork PRs whose author is not Dependabot. Manual dispatch always selects `ubuntu-24.04`, as do all other rejected contexts. The [failover runbook](2026-07-26-ci-failover-runbook.md) continues to own the independent main-CI switches and standby operation; this note adds only release-rehearsal eligibility.
+
+The runner labels are `[self-hosted, linux, x64, vm-backup]`. Runner registrations share one VM, not independent machine capacity. Each job uses its runner-private temporary volume for Node compile cache and node-gyp headers before pnpm setup, and a pnpm setup destination qualified by run, attempt, and job. The persistent pnpm store stays outside checkout cleanup; only GitHub-hosted runners restore the remote store cache. Neither rehearsal workflow saves remote caches.
+
+Checkout explicitly cleans ignored and untracked output before immutable installation and the existing builds. Full tag history, pack concurrency, dependency checks, tarball verification, and artifact retention remain unchanged. The packed-install verifier creates a fresh consumer outside the checkout, installs tarballs with npm, removes inherited Node resolution hooks, and deletes the consumer in `finally`; a warm pnpm store cannot substitute workspace links or stale build output for a tarball payload. The [npm release decision](2026-08-10-npm-release-sequences.md) still owns release families and publication. Both manual publish workflows remain entirely hosted and gain no credentials or registry changes here.
+
+## Alternatives considered
+
+Always-hosted rehearsals avoid persistent-host risk but retain all hosted minutes. Always-self-hosted rehearsals remove the portable fallback. A scheduling job or reusable workflow adds another logical job and hides the three short setup sequences. Allowing manual dispatch on arbitrary refs gives a maintainer action broader persistent-host access than the explicit event trust rule.
+
+## Consequences
+
+Unsetting the variable or changing it away from `selfhosted` routes subsequent eligible jobs to hosted Ubuntu. This is an operator-selected fallback, not automatic runner-health detection or failover for already queued jobs. The shared VM can still contend with other trusted jobs, and repository writers remain responsible for code admitted to its persistent trust domain. No workflow provisions host packages or changes global host configuration.
+
+[scripts/tests/ci-release-selfhosted.spec.ts](../../../../scripts/tests/ci-release-selfhosted.spec.ts) evaluates the committed selectors with trusted events and negative controls for forks, Dependabot, other repositories, non-master pushes, dispatches, missing PR data, and disabled switches. It pins setup ordering, checkout cleanup, hosted-only remote cache access, publication isolation, and the retained commands. Real release-build and packed-install execution remains the PR CI verification owner; selector tests do not claim to reproduce those builds.

+# Agent Note: 在持久化 Linux 运行器上执行受信任的发布演练
+
+Status: implemented
+
+[English](2026-09-06-release-rehearsal-selfhosted.md) | 中文
+
+## Problem
+
+依赖布局检查和发布打包演练消耗托管 Linux 分钟，但不需要 npm 或 API 凭据。将任意拉取请求代码或携带凭据的发布任务放到持久化共享主机会削弱隔离；复用未经清理的检出目录也会削弱打包载荷验证。
+
+## Decision
+
+[release.yml](../../../../.github/workflows/release.yml) 的两个作业和 [release-vendor.yml](../../../../.github/workflows/release-vendor.yml) 的打包作业仅在写权限维护者控制的仓库变量 `DSH_CI_FAILOVER_LINUX` 设为 `selfhosted` 时选择现有 Linux 自托管池。选择器要求当前仓库为正式仓库且触发者不是 Dependabot，然后只接纳 master 推送，或作者不是 Dependabot 的同仓库、非 fork PR（Pull Request）。手动触发始终选择 `ubuntu-24.04`，其他不满足条件的上下文也一样。[故障切换手册](2026-07-26-ci-failover-runbook.zh.md) 继续负责独立的主 CI 开关与热备操作；本记录只增加发布演练的准入规则。
+
+运行器标签为 `[self-hosted, linux, x64, vm-backup]`。运行器注册共享一台虚拟机，不代表独立机器容量。每个作业在 pnpm 设置前将 Node 编译缓存与 node-gyp 头文件放在运行器私有临时卷上，pnpm 设置目标路径包含运行、重试次数和作业标识。持久化 pnpm 存储位于检出清理范围之外；只有 GitHub 托管运行器恢复远端存储缓存。两个演练工作流都不保存远端缓存。
+
+检出操作显式清理被忽略和未跟踪的输出，再执行锁定依赖安装与现有构建。完整标签历史、打包并发、依赖检查、压缩包验证和产物保留期均保持不变。打包安装验证器在检出目录外创建全新的消费目录，用 npm 安装压缩包，移除继承的 Node 解析钩子，并在 `finally` 中删除消费目录；预热 pnpm 存储无法用工作区链接或过期构建输出代替压缩包载荷。[npm 发布决策](2026-08-10-npm-release-sequences.zh.md) 仍负责发布族与发布操作。两个手动发布工作流全部保留在托管运行器上，本改动不增加凭据，也不改变注册表。
+
+## Alternatives considered
+
+始终使用托管演练可以避免持久化主机风险，但会保留全部托管分钟。始终自托管则失去可移植回退。增加调度作业或可复用工作流会多出一个逻辑作业，并隐藏三个简短的设置序列。允许任意引用的手动触发，会让维护者操作获得比明确事件信任规则更广的持久化主机访问权限。
+
+## Consequences
+
+取消变量或将其改为非 `selfhosted` 值，会将后续符合条件的作业路由到托管 Ubuntu。这是运维人员选择的回退，不会自动探测运行器健康，也不会切换已排队的作业。共享虚拟机仍可能与其他受信任作业竞争资源；仓库写权限维护者仍对进入持久化信任域的代码负责。工作流不安装主机系统包，也不修改全局主机配置。
+
+[scripts/tests/ci-release-selfhosted.spec.ts](../../../../scripts/tests/ci-release-selfhosted.spec.ts) 使用受信任事件和 fork、Dependabot、其他仓库、非 master 推送、手动触发、缺失 PR 数据、禁用开关等负向对照求值已提交的选择器。测试固定设置顺序、检出清理、仅托管运行器访问远端缓存、发布隔离和保留命令。真实发布构建与打包安装执行仍由 PR CI 验证；选择器测试不声称重现这些构建。

+# Agent Note: Job-private Windows Python runtime CI
+
+Status: proposed
+
+English | [中文](2026-09-06-python-runtime-windows-selfhosted.zh.md)
+
+## Problem
+
+The native Python runtime matrix consumes hosted Windows capacity, but moving its build unchanged onto shared persistent runners would modify machine installation state and reuse user-level caches. The [CI failover runbook](../../implemented/process/2026-07-26-ci-failover-runbook.md) remains the owner of the existing general-purpose lanes and pool prerequisites; this proposal covers only Python runtime builds.
+
+The [read-only prerequisite probe](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012679056) found native Windows x64, Python 3.14.7 with venv/ensurepip, and enabled Developer Mode, but no Python toolcache. Linux lacked Docker, which both manylinux steps require. These observations permit a Windows-only experiment, not a claim that the runtime build passes.
+
+## Proposal
+
+Route only the Windows x64 target in [the runtime workflow](../../../../.github/workflows/build-exe-for-python-sdk.yml) to the persistent pool when `inputs.ci && !inputs.release`, the repository is the canonical repository, and the event is either a same-repository non-fork, non-Dependabot PR or a master push. `DSH_CI_FAILOVER_WINDOWS=selfhosted` enables this routing; an unset or different value keeps the lane hosted. Release/manual builds, other events, Linux/macOS targets, planning, and the SDK-wheel job remain hosted. The implementation is pending native runtime validation.
+
+The [native setup probe](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34013261224/job/101432611073) downloads Python 3.10.20, verifies command resolution and a seeded smoke venv, asserts unchanged registered Python installations and Developer Mode, and proves job-root deletion. Windows recursive removal needs bounded retries after an observed non-empty-directory failure. The workflow additionally clears the exported compile-cache path and resets temporary-directory variables before action post-steps; focused tests pin those assignments, which are not part of the cited probe commit. The focused routing tests pass, and an inverted failover condition produces three expected failures before restoration. Full executable, wheel, and live-API validation remains pending.
+
+The [private setup script](../../../../scripts/setup-python-runtime-windows.ps1) bootstraps uv 0.11.23 inside a temporary venv using the preinstalled interpreter, then downloads managed Python 3.10 into a unique job directory with `--no-bin --no-registry`. It creates a seeded tooling venv without further Python downloads. These flags exist in the [pinned uv source](https://github.com/astral-sh/uv/blob/3cdf50e0924f1ace7a92ddbac98b12a958b87688/crates/uv-cli/src/lib.rs#L6672-L6713); the [implementation](https://github.com/astral-sh/uv/blob/3cdf50e0924f1ace7a92ddbac98b12a958b87688/crates/uv/src/commands/python/install.rs#L667-L723) suppresses executable links and registry registration. CI checks Developer Mode rather than enabling it.
+
+The job owns its pnpm store, pkg/npm/node-gyp/Python/Node caches and temporary test directories. Dependency imports use copy rather than links into a shared store; hosted cache restore/save steps are skipped. An always-run cleanup removes only the recorded job root. Checkout does not persist credentials. These are resource-isolation measures, not protection against malicious code running under the same Windows account.
+
+## Alternatives considered
+
+**Cold setup-python with a private toolcache.** Rejected: the concrete Python 3.10.11 [Windows release installer](https://github.com/actions/python-versions/blob/98e79473eb342d6f43487a289ca633620404742e/installers/win-setup-template.ps1#L21-L70) removes matching machine/current-user installation records and installs for all users. A private directory does not isolate that registry state.
+
+**Administrator-preprovisioned Python 3.10.** Viable with enforced cache-hit-only use and private dependency environments, but the measured pool does not supply it. Portable uv avoids requiring a host installation change.
+
+**Migrate Linux simultaneously.** Deferred until administrator-approved Docker provisioning and manylinux validation; skipping either manylinux step would weaken the wheel compatibility check.
+
+## Acceptance criteria
+
+- Selector tests prove hosted routing for release/manual, foreign/fork/Dependabot events, non-Windows targets, and an unset or unknown switch value.
+- A trusted native Windows run builds the executable and release-shaped wheel, passes installed-wheel keyless and required live-API tests, and uploads the wheel without global Python or registry writes.
+- Concurrent jobs use distinct cache/tool roots; success, failure, and cancellation exercise cleanup without deleting another job’s paths.
+- Compare elapsed time and shared-pool load against hosted Windows before claiming cost or throughput improvement. Until then this note remains proposed.
+
+## Risks
+
+Private stores and copy imports trade warm-cache speed and disk space for bounded mutation. Portable Python can select a different 3.10 patch from setup-python. Downloads remain external dependencies; hard runner termination can prevent cleanup. Shared-account trust and pool availability remain operational limits, and the hosted fallback does not prove self-hosted readiness.

+# Agent Note: 作业私有的 Windows Python runtime CI
+
+Status: proposed
+
+[English](2026-09-06-python-runtime-windows-selfhosted.md) | 中文
+
+## 问题
+
+原生 Python runtime 矩阵消耗托管 Windows 容量，但将构建原样迁移到共享常驻运行器会修改机器安装状态并复用用户级缓存。[CI 故障切换手册](../../implemented/process/2026-07-26-ci-failover-runbook.zh.md) 继续负责现有通用通道与运行器池前置条件；本提案仅覆盖 Python runtime 构建。
+
+[只读前置条件探测](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012679056) 发现 Windows 为原生 x64，Python 3.14.7 提供 venv/ensurepip，开发人员模式已启用，但没有 Python 工具缓存。Linux 缺少两个 manylinux 步骤都依赖的 Docker。这些观测允许开展仅针对 Windows 的实验，并不证明 runtime 构建能够通过。
+
+## 提案
+
+仅当 `inputs.ci && !inputs.release`、仓库为规范仓库，且事件为同仓库非 fork、非 Dependabot 的 PR（Pull Request）或 master 推送时，将 [runtime 工作流](../../../../.github/workflows/build-exe-for-python-sdk.yml) 的 Windows x64 目标路由到常驻运行器池。`DSH_CI_FAILOVER_WINDOWS=selfhosted` 启用此路由；未设置或其他值使通道留在托管运行器。发布/手动构建、其他事件、Linux/macOS 目标、规划作业与 SDK wheel 包作业继续使用托管运行器。实现尚待原生 runtime 验证。
+
+[原生准备探测](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34013261224/job/101432611073) 下载 Python 3.10.20，验证命令解析与包含 pip 的冒烟 venv，断言已注册的 Python 安装与开发人员模式不变，并证明作业根目录已删除。观测到目录非空的删除失败后，Windows 递归删除使用有限重试。工作流另外在 action 后置步骤前清除导出的编译缓存路径并重置临时目录变量；定向测试固定这些赋值，它们不属于引用的探测提交。定向路由测试通过，反转故障切换条件会产生三个预期失败，随后恢复条件。完整可执行文件、wheel 包与真实 API 验证仍待完成。
+
+[私有准备脚本](../../../../scripts/setup-python-runtime-windows.ps1) 使用预装解释器，在临时 venv 内引导安装 uv 0.11.23，再通过 `--no-bin --no-registry` 将托管 Python 3.10 下载到唯一的作业目录。它创建包含初始工具包的工具 venv，禁止进一步下载 Python。[固定版本的 uv 源码](https://github.com/astral-sh/uv/blob/3cdf50e0924f1ace7a92ddbac98b12a958b87688/crates/uv-cli/src/lib.rs#L6672-L6713) 提供这些参数；[实现](https://github.com/astral-sh/uv/blob/3cdf50e0924f1ace7a92ddbac98b12a958b87688/crates/uv/src/commands/python/install.rs#L667-L723) 禁止创建可执行文件链接与注册表登记。CI 检查开发人员模式，不负责启用它。
+
+作业独占其 pnpm 存储、pkg/npm/node-gyp/Python/Node 缓存以及临时测试目录。依赖导入使用复制，而不是指向共享存储的链接；跳过托管缓存恢复/保存步骤。始终执行的清理步骤仅删除记录的作业根目录。检出不保留凭据。这些措施隔离资源，不能防御同一 Windows 账户下运行的恶意代码。
+
+## 已考虑的替代方案
+
+**使用私有工具缓存冷启动 setup-python。** 不采用：具体的 Python 3.10.11 [Windows 发布安装器](https://github.com/actions/python-versions/blob/98e79473eb342d6f43487a289ca633620404742e/installers/win-setup-template.ps1#L21-L70) 会删除匹配的机器/当前用户安装记录，并为所有用户安装。私有目录无法隔离这些注册表状态。
+
+**由管理员预装 Python 3.10。** 强制仅使用缓存命中路径并采用私有依赖环境时可行，但观测到的运行器池并未提供它。便携 uv 避免要求修改主机安装。
+
+**同时迁移 Linux。** 推迟到管理员批准 Docker 部署并完成 manylinux 验证之后；跳过任一 manylinux 步骤都会削弱 wheel 包兼容性检查。
+
+## 验收标准
+
+- 选择器测试证明发布/手动、外部仓库/fork/Dependabot 事件、非 Windows 目标及未设置或未知的开关值均使用托管路由。
+- 一次可信的原生 Windows 运行构建可执行文件与发布形态 wheel 包，通过安装后 wheel 包的无密钥测试及必需的真实 API 测试，并上传 wheel 包，期间不写全局 Python 或注册表。
+- 并发作业使用不同的缓存/工具根目录；成功、失败与取消路径均执行清理且不删除其他作业的路径。
+- 在宣称成本或吞吐量改善之前，对比托管 Windows 的耗时与共享池负载。此前本说明保持 proposed 状态。
+
+## 风险
+
+私有存储与复制导入以热缓存速度和磁盘空间换取受限的修改范围。便携 Python 可能选择与 setup-python 不同的 3.10 补丁版本。下载仍依赖外部服务；运行器被强制终止可能阻止清理。共享账户信任与运行器池可用性仍是运维限制，托管回退也不能证明自托管运行器已就绪。

 Use `--skip-build` when the required `lib/` artifacts already exist, or `--targets=node24-linux-x64,node24-linux-arm64,node24-macos-arm64,node24-macos-x64,node24-win-x64` to select platforms. Build each target on its native architecture. Products land in `dist-exe/` and the script syncs the selected carriers into `python/sdk-runtime/`. Windows emits `.exe` and `-rg.exe`; macOS also syncs the matching spawn helper required by `node-pty`.
 
+CI-only Windows x64 builds can use the self-hosted pool when `DSH_CI_FAILOVER_WINDOWS=selfhosted`: only same-repository non-fork, non-Dependabot pull requests and pushes to `master` qualify. The job downloads Python 3.10 into a private temporary directory without registering it in Windows, isolates build caches and test environments, and removes that directory after success or failure. Release and manual builds, Linux and macOS targets, and the SDK-wheel helper retain hosted runners. See the [runner isolation proposal](../.agents/notes/proposed/process/2026-09-06-python-runtime-windows-selfhosted.md) for image prerequisites and validation limits.
+
 ## Validate the SDK
 
 Keep the virtual environment outside `python/`, install the test group, and run the Python suite:

+仅用于 CI 的 Windows x64 构建可在 `DSH_CI_FAILOVER_WINDOWS=selfhosted` 时使用自托管池：只有同仓库、非 fork、非 Dependabot 的拉取请求以及向 `master` 的推送符合条件。作业将 Python 3.10 下载到私有临时目录而不在 Windows 中注册它，隔离构建缓存与测试环境，并在成功或失败后删除该目录。发布与手动构建、Linux 与 macOS 目标，以及 SDK wheel 辅助作业仍使用托管运行器。镜像前提与验证限制见[运行器隔离提案](../.agents/notes/proposed/process/2026-09-06-python-runtime-windows-selfhosted.zh.md)。
+
 ## 验证 SDK
 
 请将虚拟环境放在 `python/` 之外，安装测试组，然后运行 Python 测试套件：

+# Agent Note: Evidence-driven performance optimization workflow
+
+Status: implemented
+
+English | [中文](2026-09-06-evidence-driven-performance-skill.zh.md)
+
+## Problem
+
+Performance work can improve an isolated phase while moving cost into another phase, retaining more data, or skipping required behavior. Historical PR descriptions also retain abandoned implementations and estimates, so copying their apparent solution can restore a rejected design instead of addressing a current bottleneck.
+
+## Decision
+
+The [dsh-speed-up-perf skill](../../../skills/dsh-speed-up-perf/SKILL.md) guides broad surveys toward bounded, measured user paths. It combines focused attribution with independently timed backend and browser endpoints, synthetic workload distributions, comparable cold/warm and retained-memory conditions, and negative controls for tightened budgets. Its [evidence reference](../../../skills/dsh-speed-up-perf/references/pr-evidence.md) distinguishes merged implementations, superseded proposals, author-reported measurements, and estimates.
+
+The workflow requires behavior evidence independently of timing: model-visible logs, durable generation and publication rules, stream ordering, cancellation, and disposal remain obligations. Authorized private corpus inspection yields only aggregate workload inspiration; committed inputs and published artifacts contain synthetic material. Optimization PRs carry their tighter budgets, while a preceding benchmark layer can protect the measured baseline and remain independently mergeable.
+
+The [Session-opening performance-gate decision](../testing/2026-09-04-session-open-performance-gate.md) retains ownership of lane mechanics and calibration. The [simplification skill](../../../skills/dsh-find-simplifications/SKILL.md) retains ownership of deletion-oriented surveys. Neither is superseded: this workflow adds performance-specific candidate selection, measurement comparability, and stopping criteria rather than replacing their decisions.
+
+## Alternatives considered
+
+**Optimize suspicious code before measuring.** Rejected because local complexity does not identify dominant user cost and cannot establish improvement or regression protection.
+
+**Treat historical speedups as reusable prescriptions.** Rejected because representation, ownership, and lifecycle requirements change. Historical evidence generates hypotheses; current production paths and fresh measurements decide whether a change applies.
+
+**Use only microbenchmarks or only end-to-end timing.** Rejected because isolated phases can omit moved work, while aggregate timing alone cannot locate its cause. Both are required at the scope appropriate to the selected problem.
+
+## Consequences
+
+The skill adds no runtime behavior, benchmark implementation, or new CI policy. Its validation is document/link consistency and skill metadata; each future optimization supplies executable measurements and functional evidence at its owner. The finite scenario/fix scope prevents a broad performance request from becoming an unrelated architectural rewrite.

+# Agent Note: 以证据驱动的性能优化工作流
+
+Status: implemented
+
+[English](2026-09-06-evidence-driven-performance-skill.md) | 中文
+
+## Problem
+
+性能工作可能改善某个独立阶段，却把成本转移到另一阶段、保留更多数据，或跳过必要行为。历史 PR（Pull Request）描述也可能保留已放弃的实现和估计值，因此照搬其表面方案可能恢复已否决的设计，而不是解决当前瓶颈。
+
+## Decision
+
+[dsh-speed-up-perf skill](../../../skills/dsh-speed-up-perf/SKILL.md)（技能）引导广泛调查收敛到范围明确、可测量的用户路径。它结合聚焦的成本归因与独立计时的后端和浏览器端点、合成负载分布、可比较的冷态／热态与保留内存条件，以及收紧预算的负向对照。其[证据参考](../../../skills/dsh-speed-up-perf/references/pr-evidence.md)区分已合并实现、已被替代的提案、作者报告的测量值和估计值。
+
+该工作流要求独立于计时的行为证据：模型可见日志、持久化代际和发布规则、流顺序、取消及 dispose（资源释放）仍是必须满足的要求。获授权的私有语料检查仅提供聚合负载启发；提交的输入和发布的产物包含合成材料。优化 PR 携带收紧后的预算，而前置基准测试层可以保护已测基线并保持独立可合并。
+
+[会话打开性能门禁决策](../testing/2026-09-04-session-open-performance-gate.zh.md)继续负责测试通道机制与校准。[简化 skill](../../../skills/dsh-find-simplifications/SKILL.md)继续负责以删除为目标的调查。两者均未被替代：本工作流增加面向性能的候选选择、测量可比性和停止条件，而不替换它们的决策。
+
+## Alternatives considered
+
+**先优化可疑代码，再测量。** 否决，因为局部复杂度不能确定主要用户成本，也无法证明改善或防止回归。
+
+**把历史加速方案当作可复用处方。** 否决，因为表示方式、所有权和生命周期要求会变化。历史证据用于产生假设；当前生产路径与新的测量决定改动是否适用。
+
+**只使用微基准测试，或只使用端到端计时。** 否决，因为独立阶段可能遗漏被转移的工作，而总计时无法定位原因。两者都需要在与所选问题相符的范围内使用。
+
+## Consequences
+
+该 skill 不增加运行时行为、基准测试实现或新的 CI 策略。其验证涵盖文档／链接一致性和 skill 元数据；后续每项优化在其所属位置提供可执行测量与功能证据。有限的场景／修复范围防止广泛性能请求演变成无关的架构重写。

+description: 'Use when investigating or optimizing DeepSeek Harness performance, designing realistic synthetic benchmarks or CI performance gates, profiling long Sessions or Web responsiveness, or turning performance PR evidence into measured behavior-preserving fixes.'
+---
+
+# Speed Up DeepSeek Harness
+
+Turn a broad “make it faster” request into reproducible user-path measurements and small, evidence-backed fixes. This is guidance, not a quota or a script: survey broadly, follow measured cost, and reject attractive changes that do not improve the workload users actually run.
+
+## Establish scope and current authority
+
+Read [AGENTS.md](../../../AGENTS.md), [architecture](../../../docs/architecture.md), [testing policy](../../../docs/testing.md), [defensive patterns](../../../docs/defensive-patterns.md), and the affected packages’ instructions and Agent Notes. Use [CI test reliability](../dsh-ci-test-reliability/SKILL.md) for processes, clocks, browser tests, and asynchronous cleanup.
+
+Agree on the user-visible endpoint, workload range, resource constraints, acceptable minor behavior differences, and stopping rule. Keep backend and browser end-to-end measurements separate: a fast history iterator or Client fold does not prove fast transport, paint, scrolling, or input response. Exclude model/network latency when measuring local overhead, and state that exclusion rather than calling the result complete product latency.
+
+Inspect the exact current base, not just the running checkout. Study final merged diffs, owning source, tests, and resolved review threads; a PR body can describe an abandoned implementation. Separate merged, closed-unmerged, superseded, estimated, and newly measured evidence. The [PR evidence reference](references/pr-evidence.md) supplies historical leads, not authority to reintroduce their implementations.
+
+## Survey user paths, then rank candidates
+
+Delegate independent domains when breadth helps; require measurements and production call sites, not guesses. Useful domains include:
+
+- Cold profile startup, first historical read, current-generation reopen, and writable resume.
+- Many-turn and tool-heavy history, large individual messages/results, child Session listing, and repeated navigation among Sessions.
+- Initial history transport and fold, first usable browser paint, older-page loading, scrolling, tool expansion, and inactive-view activation.
+- Live streaming and reconnect, including a long active attempt, interleaved tool work, settlement, cancellation, and teardown.
+
+Vary independent cost drivers: bytes, durable events, compact records, raw deltas, turns, tools, children, and visible DOM nodes are different quantities. Do not call a large count of tiny identical messages “realistic” without checking which user operation it stresses. Include typical and tail workloads, but avoid a combinatorial matrix with no decision value.
+
+Rank candidates by observed user latency, CPU/allocations, retained memory, occurrence, and confidence. For each, name the production consumer, the repeated work, the expected complexity, the smallest falsifiable intervention, and the behavior that must remain stable. A suspicious loop, unused cache, or large file alone is not evidence of a bottleneck.
+
+## Build realistic synthetic benchmarks first
+
+Follow [benchmarks/AGENTS.md](../../../benchmarks/AGENTS.md) and the [performance-gate decision](../../notes/implemented/testing/2026-09-04-session-open-performance-gate.md). Extend the existing required lane rather than creating competing calibration or reporting infrastructure. Package-local diagnostics remain beside their owner; cross-package required cases live under the measured user path in `benchmarks/`.
+
+If the user authorizes local corpus inspection, extract only aggregate workload characteristics. Never copy prompts, outputs, paths, identities, IDs, credentials, recordings, or recognizable snippets into fixtures, logs, screenshots, PRs, or artifacts. Generate fixed inputs from reviewed constants; no benchmark depends on the user’s home, ambient repository, network service, or private data.
+
+Before implementation, record a measurement card:
+
+| Field | Required decision |
+|---|---|
+| User operation | Exact action and externally observable completion condition |
+| Workload | Fixed dimensions, distributions, construction seed/constants, and why they exercise ordinary and tail use |
+| Entry path | Production calls/composition and built artifacts; mocked external boundaries |
+| Clock | Included setup, cold/warm state, timing start/end, and excluded costs |
+| Memory | Reachable endpoint objects, baseline, GC policy, retained versus transient limits |
+| Verdict | Raw samples, chosen aggregate, calibrated absolute/ratio/memory limits, and negative control |
+| Behavior | Owning functional tests/snapshots and permitted minor differences |
+
+Measure built JavaScript under plain Node for CPU workers; source-loader overhead and module resolution are not the shipped path. Browser cases use built product assets and the supported `dsh` profile through the existing test harness. Do not add a production export solely for measurement or copy the algorithm into a “benchmark implementation.”
+
+Use fresh children and private temporary roots for cold/process-memory samples. Warm samples explicitly retain the intended cache; never let fixture setup secretly warm a cold scenario. Keep the same input, validations, completion condition, and reachable output on both sides. A parse-and-discard baseline is not comparable with validated retained history.
+
+Report all samples and the aggregate that decides the result. Use the existing shared time calibration and reviewed variance headroom; do not scale bytes, counts, or dimensionless ratios by CPU speed. Budgets are source constants, not environment overrides. Serialize measured work against other owned CPU-heavy jobs; measure reference and candidate under comparable conditions. Do not widen a budget or select a lucky run to hide a regression.
+
+Measure end-to-end latency independently from component phases. Track retained memory with intended objects still reachable, and transient pressure separately through constrained-heap completion or an appropriate peak measurement. Faster execution with unbounded retention is not an automatic win.
+
+For browser responsiveness, use real browser input and observe the resulting UI update. Include the final stall in frame/input measurements, distinguish scheduled timers from actual input, and bound synthetic producers so catch-up bursts do not invent a different workload. State whether first paint, scrolling, paging, live updates, and activated-but-hidden views are covered. Node folds, fake DOMs, and custom heartbeat events alone cannot establish browser responsiveness.
+
+## Prove the regression, then remove work
+
+Run the unoptimized workload before changing production code. Save the command, revision, runtime/platform, fixture dimensions, raw measurements, and verdict. Reduce a failing scenario until it still exercises the real bottleneck, then rank falsifiable hypotheses before patching. Use profiles, allocation samples, work counts, or phase timings to distinguish them.
+
+Common patterns worth testing, not automatic prescriptions:
+
+- Keep compact representations compact through downstream readers; avoid per-delta objects when the consumer needs settled content or one aggregate.
+- Remove duplicate parsing, copying, freezing, and validation only after identifying the actual ownership and trust transition. Typed same-process borrowing is not permission to weaken durable or wire parsing.
+- Stream artifact transformations and bound intermediate state rather than retaining every generation. Include publication, verification, and writable-readiness obligations where the user operation requires them.
+- Separate read-only preparation from write/publication work without moving awaited work past a correctness-required endpoint.
+- Defer inactive-view and collapsed-detail work; measure first activation and retained state too. Deferral is not deletion, and viewport highlighting is not full virtualization.
+- Stabilize identities and narrow subscriptions so one changed node does not invalidate an entire history; preserve update ordering and immediate-event behavior.
+- Prefer a suitable data structure to repeated shifting, scanning, or rebuilding. Measure the whole consumer path, not just the isolated container operation.
+- Use revision-keyed reuse or singleflight only with explicit invalidation, bounded retention, independent waiter cancellation, and disposal ownership. Avoid caching expanded representations merely to make repeated benchmarks look fast.
+
+Change one causal factor at a time. Re-run both the focused scenario and its end-to-end parent. Require a negative control: the tightened assertion fails on the original implementation or a controlled reintroduction of the targeted cost. A threshold so generous that the regression passes is not protection; a budget below a verified noise floor is not reliable either.
+
+## Preserve behavior and resource ownership
+
+Performance measurements complement functional evidence; they do not replace it. Run or add the narrow owning tests for output, ordering, paging, stream indexes, errors, cancellation, concurrency, and disposal as applicable. Preserve model-visible/logged equivalence, released-generation immutability, atomic publication, required validation, and writable readiness. Do not silently truncate history, skip tool results, disable invariants, or change lifecycle semantics to reach a number.
+
+State any deliberate minor visible difference and verify it through the owning keyless snapshot. For a product-visible GUI change, include the required browser evidence/GIF. Keep functional expectations independent of benchmark internals; benchmark assertions need enough evidence to reach the real endpoint, not a second semantic test suite.
+
+Reject an optimization when gains disappear end-to-end, a typical workload regresses materially, complexity outweighs a small gain, or cancellation/retention/durability cannot be explained and tested. Record the rejected hypothesis briefly instead of expanding scope to justify it.
+
+## Deliver a bounded, reviewable result
+
+Use [Agent Note rules](../../notes/README.md) for durable rationale, alternatives, calibration, exclusions, and remaining risks. Check relevant notes for supersession without turning performance work into a corpus-wide prose cleanup. Keep the reusable procedure here and scenario-specific truth with its benchmark or package owner.

+When the task requests stacked PRs, choose layers before editing and use official GitHub stacks and separate worktrees. Keep each layer mergeable: benchmark infrastructure can protect the measured baseline; the optimization layer carries its fix, functional coverage, and tighter budget. Independent bottlenecks may use separate stacks. Fix a finding in its owning layer before propagating upward.
+
+Apply [pre-push checks](../dsh-pre-push-checks/SKILL.md), report only executed evidence, and inspect CI rather than assuming local timing proves runner stability. After marking ready, evaluate review findings against code and executable evidence; reply with the reason or fix and resolve addressed threads. Do not dismiss a report merely because it came from a bot.
+
+Summarize each result as: workload → before/after absolute values and ratio → endpoint and memory semantics → behavior evidence → negative control → exact checks → exclusions. Separate author-reported historical numbers, fresh local measurements, and CI evidence. Stop at the agreed scenario/fix scope; retain a short ranked follow-up list instead of chasing unrelated opportunities.

+# Performance PR evidence
+
+## Scope
+
+This reference records historical evidence for choosing performance experiments, not current runtime authority. PR measurements are author-reported and were not rerun for this survey. Source inspection used revision `bdbf976558f54d6bfa775b875702dcebc355a554`; PR bodies, selected diffs, and review discussions were read through GitHub. No private Session contents were inspected or copied. Consult the current [benchmark instructions](../../../../benchmarks/AGENTS.md), [testing policy](../../../../docs/testing.md), source, and owning Agent Notes before implementation.
+
+## Session performance series
+
+| Primary source | Scenario and reported result | Reusable finding |
+|---|---|---|
+| [#3535](https://github.com/deepseek-harness/deepseek-harness/pull/3535), merged | Synthetic first open, first Host history, cold Agent resume, and Client fold. The [final design comment](https://github.com/deepseek-harness/deepseek-harness/pull/3535#issuecomment-5552779119) reports negative controls: first-open 4,394 ms against 550 ms; first-history 4,452 against 550; Agent resume 4,333 against 450; all three first-open 128 MB checks exhausted heap; Client fold 123.9 ms / 10.84× against 40 ms / 3.125×. | Establish executable positive and negative controls before optimization. The original PR body describes an earlier package-local design; the merged diff and final comment describe centralized compiled workers. #3587 was folded back into this PR. |
+| [#3536](https://github.com/deepseek-harness/deepseek-harness/pull/3536), closed unmerged | Repeated artifact snapshots/freezes/validation occupied approximately 70% of profiled CPU. A 127,400-event synthetic open fell from 4,734–4,921 ms to 707–823 ms with identity reuse. | This implementation was superseded by streaming migration. Do not revive its snapshot registry without proving that repeated whole-artifact work still exists. |
+| [#3585](https://github.com/deepseek-harness/deepseek-harness/pull/3585), merged | On one 116,228,655-byte historical input, physical decode fell from 7.527 s / 7,219 MB peak RSS to 1.467 s / 908 MB. Whole-artifact migration exhausted heap before availability; streaming migration plus serial publication completed in 6.241 s, with 2.107 GB peak RSS and 477 MB retained heap. Settled Client fold of 500,000 deltas took 3.2 ms. | Keep packed runs compact through synchronous stateful stages, retain only the final event array, and let one outer scheduler own yielding. Derive settled UI from final message content instead of replaying every delta. Attribution estimates in the PR overlap and cannot be added. |
+| [#3586](https://github.com/deepseek-harness/deepseek-harness/pull/3586), merged | Same current-v2 file, three-sample medians: opening snapshot 2,011.4→1,027.9 ms; Session restore 598.5→16.0 ms; retained heap 1,025.3→478.7 MB. Historical opening snapshot measured 3,109.7 ms; writable Agent resume 4,888.6 ms, including 2,023.8 ms publication. | Separate read-only preparation from write publication. Transfer explicit immutable ownership instead of cloning/freezing at every consumer. Share preparation by source revision, with caller-local cancellation. |
+| [#3537](https://github.com/deepseek-harness/deepseek-harness/pull/3537), merged | Five-sample medians on the synthetic 200-turn Session: first-open projection 28.0→5.4 ms, total 76.9→50.0 ms, peak RSS 137.2→94.9 MB; reopen total 37.7→24.4 ms. | Compact-record readers answer stats, usage, text, and image questions without allocating expanded streams. Expanded-stream caching can retain approximately ten times the compact representation for the Session lifetime. The final PR excludes Chat/Trajectory changes already supplied by #3585. |
+
+The source inspection revision predates #3537. Its results therefore come from its merged PR, not from running the inspected checkout.
+
+## Benchmark infrastructure at the inspected revision
+
+The [benchmark workspace instructions](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/AGENTS.md) require fixed synthetic inputs, production entry points, private temporary roots, bounded children, and cleanup after failures. Cross-package cases are grouped by user path; package-local diagnostics remain separate.
+
+- The [required PR job](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/.github/workflows/ci.yml#L159-L203) selects Node 24 and runs the benchmark command alone, with a 30-minute deadline. [Package scripts](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/package.json#L40-L65) build libraries and workers before Vitest orchestration; measured work uses plain Node and built package exports, not TSX.
+- The [Session matrix](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/session-open/session-open.bench.ts#L273-L355) contains 12 cases: two disk states × three endpoints × normal-heap or constrained-heap execution. Disk states are historical-v0 first open and fresh-process current-v2 reopen. Endpoints are four-phase preparation, first Host history snapshot, and cold Agent resume. Normal timings use five-process medians; separate 128 MB old-space children check completion.
+- The [worker timing boundaries](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/session-open/session-open.worker.ts#L160-L287) exclude imports, Host initialization, and fixture setup. First history ends at the first iterator snapshot, before live promotion, network transfer, Client fold, or paint. Forced-GC retained memory keeps the measured endpoint reachable. CPU, peak RSS, external memory, and array buffers are reported; only Agent retained heap has a separate resident-memory budget.
+- [Calibration](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/support/calibration.ts) multiplies reference times by 2 for CI and 1.25 for variance. Memory and dimensionless ratios receive no machine-time multiplier. CI uses reviewed constants, not a historical checkout on every run. [Client fold](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/conversation-fold/conversation-fold.bench.client.ts) uses 200 replies, equal event/record counts with different embedded delta counts, minimum-of-three samples, and absolute plus scaling limits.
+- The [manual Web performance inventory](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/vitest.web.perf.config.ts) and [browser stress inventory](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/vitest.web-stress.config.ts) are explicitly outside default CI. Their existence does not imply required browser latency coverage.
+
+The benchmark Agent Note at this revision still says historical read-only phase opens include publication. The actual worker calls read access; #3586 separates preparation from publication. Use the worker and persistence source for that timing distinction.
+
+## Additional merged performance work
+
+| Primary source | Evidence | Pattern or limitation |
+|---|---|---|
+| [#2587](https://github.com/deepseek-harness/deepseek-harness/pull/2587) | Historical 416,756-event workload: 696 packed records; client history 4,682→276 ms; sampled additional V8 peak 612.5→199.4 MB. | Preserve compact representation through validation, indexing, and folding. These historical cardinalities are not the later v2 format. The [successor diagnostic](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/packages/client/ui-conversation/tests/history-transport.perf.client.ts#L410-L480) compares embedded streams and equal final-state digests. |
+| [#3331](https://github.com/deepseek-harness/deepseek-harness/pull/3331) | 10,000 collapsed Tool rows with 1 KiB JSON: 22.5→7.5 ms, retained heap 12.2→1.6 MiB. Inactive Trajectory with 10,000 individual flushes: 4,082→15.5 ms. | Defer unused JSON parsing and target materialization; share historical Inbox arrays. Context folding and first target activation still cost work. |
+| [#3391](https://github.com/deepseek-harness/deepseek-harness/pull/3391) | Per-node subscriptions, stable identities, CSS replacing layout reads, bounded Trajectory inputs, and batched publication. | Its 10,000-node timing table is explicitly estimated, not measured browser evidence. |
+| [#3383](https://github.com/deepseek-harness/deepseek-harness/pull/3383) | Viewport-triggered syntax highlighting. | One-shot deferral is not virtualization: visited blocks retain token DOM. |
+| [#3292](https://github.com/deepseek-harness/deepseek-harness/pull/3292) | Two-million-item FIFO drain: 9.656 ms median, excluding enqueue. | Deque avoids array-shift copying; it does not provide admission control or backpressure. |
+| [#1161](https://github.com/deepseek-harness/deepseek-harness/pull/1161) | Keyless 100,000-reasoning-chunk browser stress, paced at 128 chunks per 16 ms, with heartbeat and scheduled-event latency budgets. | Scheduled synthetic events are not real pointer/keyboard interactions; producer catch-up and heartbeat endpoints need scrutiny. |
+
+The [complex-history diagnostic](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/apps/web/tests/complex-history.perf.ts) supplies broader synthetic building blocks: 1,000 sidebar Sessions, 500 turns/tools, a 24-turn initial window, continued turns, history/search/warm switches, and a 100-turn soak. It records browser task/layout/style time, DOM/listener counts, and forced-GC heap. Its timings are observational rather than required performance verdicts.
+
+## Review pitfalls worth retaining
+
+- Compare equivalent work and ownership. The [#2587 baseline review](https://github.com/deepseek-harness/deepseek-harness/pull/2587#discussion_r3803082730) requires full-response validation and retained parsed arrays on both sides, not parse-and-discard on one side.
+- Preserve exact cancellation and revision semantics. [#3586 cancellation](https://github.com/deepseek-harness/deepseek-harness/pull/3586#discussion_r3940578092) lets started publication settle, then rejects the canceled write open and releases its lease; [source drift](https://github.com/deepseek-harness/deepseek-harness/pull/3586#discussion_r3940569241) invalidates preparation rather than silently replacing returned history.
+- Record validation tradeoffs explicitly. [#3585](https://github.com/deepseek-harness/deepseek-harness/pull/3585#discussion_r3940324353) deferred full historical scalar payload-member validation for performance; #3586 distinguishes ordinary current-file restore from strict publication-worker replay. [#3537 readers](https://github.com/deepseek-harness/deepseek-harness/pull/3537#discussion_r3942974015) trust typed records rather than validating arbitrary durable data.
+- Measure the producer as well as the renderer. [#1161 review](https://github.com/deepseek-harness/deepseek-harness/pull/1161#discussion_r3699970161) identifies catch-up bursts; [heartbeat review](https://github.com/deepseek-harness/deepseek-harness/pull/1161#discussion_r3699970162) identifies final-stall undercount. These are measurement caveats, not newly reproduced failures.
+- An isolated job does not guarantee an isolated physical host. [#3535 failover review](https://github.com/deepseek-harness/deepseek-harness/pull/3535#discussion_r3927945561) warns that multiple runners on one standby VM can contaminate wall-clock budgets.
+
+## Bounded scenario hypotheses
+
+These candidates require profiling; they are not claims of defects.
+
+1. Add tool-heavy and many-turn distributions beside the text/reasoning Session workload. Keep read-only opening, current reopen, and writable resume distinct, with component attribution and independent end-to-end clocks.
+2. Measure many-child-Session list/observe-to-resume work before changing caches. #3586 identifies bulk subagent body reads as remaining work; avoid optimizing an already removed artifact-snapshot design.
+3. Measure browser first usable paint, older-page loading, scrolling, expanding one large result, and first Trajectory activation separately from Host snapshot latency. Reuse complex-history fixtures while adding explicit, calibrated verdicts and real interaction probes.
+4. Isolate reconnect during a long active Assistant attempt. The [inspected reconnect implementation](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/packages/api/session-controller/src/client/sessions/assistant-stream.ts#L52-L94) expands a compact baseline into transient entries, unlike settled history. Preserve ordering, attempt identity, and next-index semantics in any experiment.

 ## Decision
 
-The [dsh-speed-up-perf skill](../../../skills/dsh-speed-up-perf/SKILL.md) guides broad surveys toward bounded, measured user paths. It combines focused attribution with independently timed backend and browser endpoints, synthetic workload distributions, comparable cold/warm and retained-memory conditions, and negative controls for tightened budgets. Its [evidence reference](../../../skills/dsh-speed-up-perf/references/pr-evidence.md) distinguishes merged implementations, superseded proposals, author-reported measurements, and estimates.
+The [dsh-speed-up-perf skill](../../../skills/dsh-speed-up-perf/SKILL.md) guides broad surveys toward bounded, measured user paths. It combines focused attribution with independently timed backend and browser endpoints, synthetic workload distributions, comparable cold/warm and retained-memory conditions, and negative controls for tightened budgets. The historical evidence below distinguishes merged implementations, superseded proposals, author-reported measurements, and estimates.
 
 The workflow requires behavior evidence independently of timing: model-visible logs, durable generation and publication rules, stream ordering, cancellation, and disposal remain obligations. Authorized private corpus inspection yields only aggregate workload inspiration; committed inputs and published artifacts contain synthetic material. Optimization PRs carry their tighter budgets, while a preceding benchmark layer can protect the measured baseline and remain independently mergeable.
 
 The [Session-opening performance-gate decision](../testing/2026-09-04-session-open-performance-gate.md) retains ownership of lane mechanics and calibration. The [simplification skill](../../../skills/dsh-find-simplifications/SKILL.md) retains ownership of deletion-oriented surveys. Neither is superseded: this workflow adds performance-specific candidate selection, measurement comparability, and stopping criteria rather than replacing their decisions.
 
+## Historical evidence
+
+These are author-reported historical measurements, not benchmarks rerun for this workflow. Final merged diffs and owning source take precedence over original PR descriptions. The rejected intermediate proposal is retained only to explain why identity registries are not a general prescription.
+
+| Evidence | Measured path and result | Reusable lesson |
+|---|---|---|
+| [#3535](https://github.com/deepseek-harness/deepseek-harness/pull/3535), merged | The [final benchmark design](https://github.com/deepseek-harness/deepseek-harness/pull/3535#issuecomment-5552779119) reports a 4,394 ms first-open negative control against 550 ms, first-history 4,452 against 550, resume 4,333 against 450, and 128 MB heap failures. Client fold: 123.9 ms / 10.84× against 40 ms / 3.125×. | Built-JS user-path gates and positive/negative controls matter more than an earlier PR-body design. |
+| [#3536](https://github.com/deepseek-harness/deepseek-harness/pull/3536), closed unmerged | Repeated snapshot/freeze work occupied about 70% of profiled CPU; synthetic open improved from 4,734–4,921 to 707–823 ms. | Streaming migration superseded this identity-registry proposal. Do not revive it without current ownership evidence. |
+| [#3585](https://github.com/deepseek-harness/deepseek-harness/pull/3585), merged | Historical physical decode: 7.527 s / 7,219 MB peak RSS to 1.467 s / 908 MB; streaming migration with serial publication: 6.241 s, 2.107 GB peak, 477 MB retained. Settled 500,000-delta Client fold: 3.2 ms. | Keep representations compact across consumers; bound intermediate state. Attribution estimates overlap and cannot be added. |

+| [#3537](https://github.com/deepseek-harness/deepseek-harness/pull/3537), merged | Synthetic 200-turn projection: 28→5.4 ms; total: 76.9→50 ms; peak RSS: 137.2→94.9 MB. | Read stats, usage, text and image references per compact record. Expanded-stream caching retains unnecessary representation cost. Chat/Trajectory belong to the preceding migration change. |
+| [#2587](https://github.com/deepseek-harness/deepseek-harness/pull/2587), merged | Historical 416,756 events represented by 696 records: client history 4,682→276 ms; sampled additional V8 peak 612.5→199.4 MB. | Preserve compactness through validation and folding; [baseline review](https://github.com/deepseek-harness/deepseek-harness/pull/2587#discussion_r3803082730) requires equal validation and retained output, not parse-and-discard. |
+| [#3331](https://github.com/deepseek-harness/deepseek-harness/pull/3331), merged | 10,000 collapsed tool rows: 22.5→7.5 ms, retained 12.2→1.6 MiB; inactive Trajectory flushes: 4,082→15.5 ms. | Defer unused parsing and materialization; first activation and retained Context still cost work. |
+| [#3391](https://github.com/deepseek-harness/deepseek-harness/pull/3391) and [#3383](https://github.com/deepseek-harness/deepseek-harness/pull/3383), merged | Narrow subscriptions, stable identities, batched publication, and viewport-triggered highlighting. The 10,000-node timing table is estimated, not browser measurement. | Deferral is not virtualization: visited token DOM remains retained. |
+| [#3292](https://github.com/deepseek-harness/deepseek-harness/pull/3292), merged | Two-million-item FIFO drain: 9.656 ms median, excluding enqueue. | A deque removes shift copying, not queue admission or backpressure obligations. |
+| [#1161](https://github.com/deepseek-harness/deepseek-harness/pull/1161), merged | Keyless 100,000-chunk browser stress at 128 chunks per 16 ms. | [Producer catch-up](https://github.com/deepseek-harness/deepseek-harness/pull/1161#discussion_r3699970161) and [final heartbeat stalls](https://github.com/deepseek-harness/deepseek-harness/pull/1161#discussion_r3699970162) can distort measurements; scheduled events are not trusted keyboard/pointer input. |
+
+The [cancellation review](https://github.com/deepseek-harness/deepseek-harness/pull/3586#discussion_r3940578092), [source-revision review](https://github.com/deepseek-harness/deepseek-harness/pull/3586#discussion_r3940569241), and [typed-reader review](https://github.com/deepseek-harness/deepseek-harness/pull/3537#discussion_r3942974015) illustrate why removing repeated work does not authorize deleting validation or publication obligations. A [standby-runner review](https://github.com/deepseek-harness/deepseek-harness/pull/3535#discussion_r3927945561) distinguishes a dedicated job from an isolated physical host.

 ## Alternatives considered
 
 **Optimize suspicious code before measuring.** Rejected because local complexity does not identify dominant user cost and cannot establish improvement or regression protection.

-## Scope
-
-This reference records historical evidence for choosing performance experiments, not current runtime authority. PR measurements are author-reported and were not rerun for this survey. Source inspection used revision `bdbf976558f54d6bfa775b875702dcebc355a554`; PR bodies, selected diffs, and review discussions were read through GitHub. No private Session contents were inspected or copied. Consult the current [benchmark instructions](../../../../benchmarks/AGENTS.md), [testing policy](../../../../docs/testing.md), source, and owning Agent Notes before implementation.

The original PR body describes an earlier package-local design; the merged diff and final comment describe centralized compiled workers. #3587 was folded back into this PR. |
-| [#3536](https://github.com/deepseek-harness/deepseek-harness/pull/3536), closed unmerged | Repeated artifact snapshots/freezes/validation occupied approximately 70% of profiled CPU. A 127,400-event synthetic open fell from 4,734–4,921 ms to 707–823 ms with identity reuse. | This implementation was superseded by streaming migration. Do not revive its snapshot registry without proving that repeated whole-artifact work still exists. |
-| [#3585](https://github.com/deepseek-harness/deepseek-harness/pull/3585), merged | On one 116,228,655-byte historical input, physical decode fell from 7.527 s / 7,219 MB peak RSS to 1.467 s / 908 MB. Whole-artifact migration exhausted heap before availability; streaming migration plus serial publication completed in 6.241 s, with 2.107 GB peak RSS and 477 MB retained heap. Settled Client fold of 500,000 deltas took 3.2 ms. | Keep packed runs compact through synchronous stateful stages, retain only the final event array, and let one outer scheduler own yielding. Derive settled UI from final message content instead of replaying every delta. Attribution estimates in the PR overlap and cannot be added. |

Historical opening snapshot measured 3,109.7 ms; writable Agent resume 4,888.6 ms, including 2,023.8 ms publication. | Separate read-only preparation from write publication.

-
-The source inspection revision predates #3537. Its results therefore come from its merged PR, not from running the inspected checkout.

-## Benchmark infrastructure at the inspected revision
-
-The [benchmark workspace instructions](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/AGENTS.md) require fixed synthetic inputs, production entry points, private temporary roots, bounded children, and cleanup after failures. Cross-package cases are grouped by user path; package-local diagnostics remain separate.
-
-- The [required PR job](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/.github/workflows/ci.yml#L159-L203) selects Node 24 and runs the benchmark command alone, with a 30-minute deadline. [Package scripts](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/package.json#L40-L65) build libraries and workers before Vitest orchestration; measured work uses plain Node and built package exports, not TSX.
-- The [Session matrix](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/session-open/session-open.bench.ts#L273-L355) contains 12 cases: two disk states × three endpoints × normal-heap or constrained-heap execution. Disk states are historical-v0 first open and fresh-process current-v2 reopen. Endpoints are four-phase preparation, first Host history snapshot, and cold Agent resume. Normal timings use five-process medians; separate 128 MB old-space children check completion.
-- The [worker timing boundaries](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/session-open/session-open.worker.ts#L160-L287) exclude imports, Host initialization, and fixture setup. First history ends at the first iterator snapshot, before live promotion, network transfer, Client fold, or paint. Forced-GC retained memory keeps the measured endpoint reachable. CPU, peak RSS, external memory, and array buffers are reported; only Agent retained heap has a separate resident-memory budget.
-- [Calibration](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/support/calibration.ts) multiplies reference times by 2 for CI and 1.25 for variance. Memory and dimensionless ratios receive no machine-time multiplier. CI uses reviewed constants, not a historical checkout on every run. [Client fold](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/benchmarks/conversation-fold/conversation-fold.bench.client.ts) uses 200 replies, equal event/record counts with different embedded delta counts, minimum-of-three samples, and absolute plus scaling limits.
-- The [manual Web performance inventory](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/vitest.web.perf.config.ts) and [browser stress inventory](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/vitest.web-stress.config.ts) are explicitly outside default CI. Their existence does not imply required browser latency coverage.
-
-The benchmark Agent Note at this revision still says historical read-only phase opens include publication. The actual worker calls read access; #3586 separates preparation from publication. Use the worker and persistence source for that timing distinction.
-
-## Additional merged performance work
-
-| Primary source | Evidence | Pattern or limitation |
-|---|---|---|
-| [#2587](https://github.com/deepseek-harness/deepseek-harness/pull/2587) | Historical 416,756-event workload: 696 packed records; client history 4,682→276 ms; sampled additional V8 peak 612.5→199.4 MB. | Preserve compact representation through validation, indexing, and folding. These historical cardinalities are not the later v2 format. The [successor diagnostic](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/packages/client/ui-conversation/tests/history-transport.perf.client.ts#L410-L480) compares embedded streams and equal final-state digests. |
-| [#3331](https://github.com/deepseek-harness/deepseek-harness/pull/3331) | 10,000 collapsed Tool rows with 1 KiB JSON: 22.5→7.5 ms, retained heap 12.2→1.6 MiB. Inactive Trajectory with 10,000 individual flushes: 4,082→15.5 ms. | Defer unused JSON parsing and target materialization; share historical Inbox arrays. Context folding and first target activation still cost work. |
-| [#3391](https://github.com/deepseek-harness/deepseek-harness/pull/3391) | Per-node subscriptions, stable identities, CSS replacing layout reads, bounded Trajectory inputs, and batched publication. | Its 10,000-node timing table is explicitly estimated, not measured browser evidence. |
-| [#3383](https://github.com/deepseek-harness/deepseek-harness/pull/3383) | Viewport-triggered syntax highlighting. | One-shot deferral is not virtualization: visited blocks retain token DOM. |
-| [#3292](https://github.com/deepseek-harness/deepseek-harness/pull/3292) | Two-million-item FIFO drain: 9.656 ms median, excluding enqueue. | Deque avoids array-shift copying; it does not provide admission control or backpressure. |
-| [#1161](https://github.com/deepseek-harness/deepseek-harness/pull/1161) | Keyless 100,000-reasoning-chunk browser stress, paced at 128 chunks per 16 ms, with heartbeat and scheduled-event latency budgets. | Scheduled synthetic events are not real pointer/keyboard interactions; producer catch-up and heartbeat endpoints need scrutiny. |
-
-The [complex-history diagnostic](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/apps/web/tests/complex-history.perf.ts) supplies broader synthetic building blocks: 1,000 sidebar Sessions, 500 turns/tools, a 24-turn initial window, continued turns, history/search/warm switches, and a 100-turn soak. It records browser task/layout/style time, DOM/listener counts, and forced-GC heap. Its timings are observational rather than required performance verdicts.
-
-## Review pitfalls worth retaining
-
-- Compare equivalent work and ownership. The [#2587 baseline review](https://github.com/deepseek-harness/deepseek-harness/pull/2587#discussion_r3803082730) requires full-response validation and retained parsed arrays on both sides, not parse-and-discard on one side.
-- Preserve exact cancellation and revision semantics. [#3586 cancellation](https://github.com/deepseek-harness/deepseek-harness/pull/3586#discussion_r3940578092) lets started publication settle, then rejects the canceled write open and releases its lease; [source drift](https://github.com/deepseek-harness/deepseek-harness/pull/3586#discussion_r3940569241) invalidates preparation rather than silently replacing returned history.
-- Record validation tradeoffs explicitly. [#3585](https://github.com/deepseek-harness/deepseek-harness/pull/3585#discussion_r3940324353) deferred full historical scalar payload-member validation for performance; #3586 distinguishes ordinary current-file restore from strict publication-worker replay. [#3537 readers](https://github.com/deepseek-harness/deepseek-harness/pull/3537#discussion_r3942974015) trust typed records rather than validating arbitrary durable data.
-- Measure the producer as well as the renderer. [#1161 review](https://github.com/deepseek-harness/deepseek-harness/pull/1161#discussion_r3699970161) identifies catch-up bursts; [heartbeat review](https://github.com/deepseek-harness/deepseek-harness/pull/1161#discussion_r3699970162) identifies final-stall undercount. These are measurement caveats, not newly reproduced failures.
-- An isolated job does not guarantee an isolated physical host. [#3535 failover review](https://github.com/deepseek-harness/deepseek-harness/pull/3535#discussion_r3927945561) warns that multiple runners on one standby VM can contaminate wall-clock budgets.
-
-## Bounded scenario hypotheses
-
-These candidates require profiling; they are not claims of defects.
-
-1. Add tool-heavy and many-turn distributions beside the text/reasoning Session workload. Keep read-only opening, current reopen, and writable resume distinct, with component attribution and independent end-to-end clocks.
-2. Measure many-child-Session list/observe-to-resume work before changing caches. #3586 identifies bulk subagent body reads as remaining work; avoid optimizing an already removed artifact-snapshot design.
-3. Measure browser first usable paint, older-page loading, scrolling, expanding one large result, and first Trajectory activation separately from Host snapshot latency. Reuse complex-history fixtures while adding explicit, calibrated verdicts and real interaction probes.
-4. Isolate reconnect during a long active Assistant attempt. The [inspected reconnect implementation](https://github.com/deepseek-harness/deepseek-harness/blob/bdbf976558f54d6bfa775b875702dcebc355a554/packages/api/session-controller/src/client/sessions/assistant-stream.ts#L52-L94) expands a compact baseline into transient entries, unlike settled history. Preserve ordering, attempt identity, and next-index semantics in any experiment.

+# Agent Note: Measured GitHub-hosted PR preview sizing
+
+Status: implemented
+
+English | [中文](2026-09-06-preview-hosted-runner-sizing.zh.md)
+
+## Problem
+
+PR previews build the full workspace and browser-worker VFS image. A lower per-minute runner price does not guarantee lower job cost because GitHub rounds each job upward to whole minutes. Moving previews to persistent self-hosted machines also changes isolation and is outside this decision.
+
+## Decision
+
+The [preview workflow](../../../../.github/workflows/build-preview-cloudflare.yml) uses standard GitHub-hosted `ubuntu-24.04`. Build, cache, deployment, protected-image verification, and comment semantics remain unchanged. The [sizing reference](../../../../.github/preview-sizing/README.md) owns comparison requirements. The separate CI [failover runbook](2026-07-26-ci-failover-runbook.md) retains its independent runner-switch decision; previews do not use those switches.
+
+### Measurements
+
+[Experiment 34012729982](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012729982) succeeds for all eight size/cache combinations plus one cache seed. Every measured job checks out SHA `9149d7e7ef945b5601711badd3cf63d58ab384f5`, uses Node 24.19.0 and pnpm 11.7.0, and executes immutable install, full workspace build, preview/VFS packing, and local upload shaping with gzip integrity verification. Warm jobs restore one exact run-private pnpm cache; cold jobs skip restoration but contain pnpm bootstrap files. No compiled outputs are restored.
+
+| Runner | Cold / warm job seconds | Rounded minutes each | USD each | Workspace seconds cold / warm | Preview seconds cold / warm |
+|---|---:|---:|---:|---:|---:|
+| standard, 2 vCPU | 202 / 203 | 4 | 0.024 | 138.92 / 147.21 | 12.65 / 12.94 |
+| larger, 4 vCPU | 177 / 162 | 3 | 0.036 | 124.21 / 114.86 | 10.77 / 9.88 |
+| larger, 8 vCPU | 154 / 154 | 3 | 0.066 | 110.51 / 110.77 | 9.20 / 9.21 |
+| larger, 16 vCPU | 124 / 125 | 3 | 0.126 | 90.57 / 84.99 | 7.62 / 7.33 |
+
+Using [published rates](https://docs.github.com/en/billing/reference/actions-runner-pricing), measured jobs total $0.504; the 60-second standard seed adds $0.006. The $0.510 gross compute estimate includes setup, restoration, measurement upload, and cleanup, but excludes storage and account discounts. Standard costs 80.95% less than 16-core and 33.33% less than 4-core in each sampled cache state. It adds 78 seconds against the corresponding 16-core job.
+
+Standard jobs expose two vCPUs and 7.75 GiB RAM. Workspace maximum process RSS is 2.86 / 2.76 GiB; preview maximum process RSS is 0.76 / 0.74 GiB. Both complete without an OOM or timeout. GNU time RSS is not simultaneous process-tree memory. These samples establish successful execution, not a permanent memory guarantee.
+
+The comparison fixes source, lockfile, commands, and runtime versions, not physical CPUs or image release: standard and 4-core use image 20260831.293.1; 8-core and 16-core use 20260823.283.1. CPUs vary among AMD EPYC 9V74/7763 and Intel Xeon 8370C/8573C. One sample per cache state measures the offered labels, not isolated CPU scaling or statistical repeatability.
+
+The experiment does not deploy or access Cloudflare credentials. Measurement upload takes zero to one second; warm-cache restore takes six to ten seconds. For context, [production job 101428009994](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34011495156/job/101428009994) spends 14 seconds uploading, one second verifying, and two seconds commenting on a different SHA. Adding that overhead to this experiment is a projection, not a measured standard-runner publication result. The actual PR preview workflow owns deployment confirmation.
+
+## Alternatives considered
+
+**Keep 16-core.** It provides the shortest measured job, but costs $0.102 more per sample for a 78-second improvement. Preview builds do not justify that premium for this cost-focused decision.
+
+**Select 4-core or 8-core.** Both succeed and shorten builds, but their rounded sample costs exceed standard Ubuntu. Four-core retains more RAM and disk headroom if future workloads exhaust standard capacity; such a change requires new measurements.
+
+**Move to self-hosted.** Rejected by scope: previews remain on GitHub CI. The existing Linux and Windows registrations can share persistent hosts; their dependency, store-volume, and cleanup assumptions do not apply to fresh hosted VMs. No failover or trust condition changes.
+
+## Consequences
+
+Previews trade approximately 78 seconds of sampled build-job latency for lower compute cost. Production Cloudflare latency, image rollout variance, future build growth, and broader success rates remain observable limitations. No hourly or monthly savings are extrapolated from this single experiment. The temporary benchmark workflow and its safety test are absent from the final tree; the experiment commits and linked run preserve the method and evidence.
+
+The executed [focused regression](../../../../scripts/preview-workflow.spec.ts) pins hosted routing, PR triggers and permissions, immutable full builds, restore-only caching, publication shaping, protected-image checks, and idempotent comments. A physical self-hosted routing mutation fails its routing assertion; restoration passes all three tests. No model-visible runtime behavior changes, so no Session snapshot changes are required.

+# Agent Note: 基于测量的 GitHub 托管 PR 预览规格
+
+Status: implemented
+
+[English](2026-09-06-preview-hosted-runner-sizing.md) | 中文
+
+## 问题
+
+PR（Pull Request）预览构建完整工作区及浏览器 worker VFS 镜像。较低的每分钟运行器价格不能保证较低的作业成本，因为 GitHub 将每个作业向上取整至整分钟。将预览移至持久化自托管机器还会改变隔离方式，不属于本决策范围。
+
+## 决策
+
+[预览工作流](../../../../.github/workflows/build-preview-cloudflare.yml) 使用标准 GitHub 托管 `ubuntu-24.04`。构建、缓存、部署、受保护镜像验证及评论语义保持不变。[规格参考](../../../../.github/preview-sizing/README.zh.md) 负责比较要求。独立的 CI [故障切换手册](2026-07-26-ci-failover-runbook.zh.md) 保留其运行器切换决策；预览不使用这些开关。
+
+### 测量
+
+[实验 34012729982](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012729982) 的八种规格/缓存组合及一个缓存预热作业均成功。每个测量作业检出 SHA `9149d7e7ef945b5601711badd3cf63d58ab384f5`，使用 Node 24.19.0 与 pnpm 11.7.0，并执行不可变安装、完整工作区构建、预览/VFS 打包，以及含 gzip 完整性验证的本地上传内容整理。热作业恢复同一个运行私有精确 pnpm 缓存；冷作业跳过恢复，但包含 pnpm 引导安装文件。不恢复编译产物。
+
+| 运行器 | 冷 / 热作业秒数 | 各自取整分钟数 | 各自美元费用 | 冷 / 热工作区秒数 | 冷 / 热预览秒数 |
+|---|---:|---:|---:|---:|---:|
+| 标准，2 vCPU | 202 / 203 | 4 | 0.024 | 138.92 / 147.21 | 12.65 / 12.94 |
+| 大型，4 vCPU | 177 / 162 | 3 | 0.036 | 124.21 / 114.86 | 10.77 / 9.88 |
+| 大型，8 vCPU | 154 / 154 | 3 | 0.066 | 110.51 / 110.77 | 9.20 / 9.21 |
+| 大型，16 vCPU | 124 / 125 | 3 | 0.126 | 90.57 / 84.99 | 7.62 / 7.33 |
+
+按[公开费率](https://docs.github.com/en/billing/reference/actions-runner-pricing)，测量作业合计 $0.504；60 秒标准预热作业增加 $0.006。$0.510 总计算费用估算包含设置、恢复、测量上传及清理，但不含存储和账户折扣。在每种采样缓存状态下，标准运行器比 16 核低 80.95%，比 4 核低 33.33%。相比对应的 16 核作业增加 78 秒。
+
+标准作业提供两个 vCPU 与 7.75 GiB 内存。工作区最大进程 RSS 为 2.86 / 2.76 GiB；预览最大进程 RSS 为 0.76 / 0.74 GiB。两者均未发生 OOM 或超时并完成。GNU time RSS 不是进程树同时占用的内存总量。这些样本证明成功执行，而非永久内存保证。
+
+比较固定源代码、锁文件、命令和运行时版本，但不固定物理 CPU 或镜像版本：标准与 4 核使用镜像 20260831.293.1；8 核与 16 核使用 20260823.283.1。CPU 包括 AMD EPYC 9V74/7763 与 Intel Xeon 8370C/8573C。每种缓存状态的单个样本测量所提供的标签，而非独立 CPU 扩展性或统计可重复性。
+
+实验不部署，也不访问 Cloudflare 凭据。测量上传耗时零至一秒；热缓存恢复耗时六至十秒。作为背景，[生产作业 101428009994](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34011495156/job/101428009994) 在不同 SHA 上上传耗时 14 秒、验证一秒、评论两秒。将该开销加至本实验属于推算，而非已测量的标准运行器发布结果。实际 PR 预览工作流负责部署确认。
+
+## 考虑过的替代方案
+
+**保留 16 核。** 它提供最短的测量作业，但为 78 秒改善使每个样本增加 $0.102。对于本次以成本为重点的决策，预览构建不值得这项溢价。
+
+**选择 4 核或 8 核。** 两者均成功并缩短构建，但取整后的样本费用高于标准 Ubuntu。若未来工作负载耗尽标准容量，4 核可保留更多内存与磁盘余量；这样的变更需要新测量。
+
+**移至自托管。** 因范围限制而拒绝：预览保留在 GitHub CI。现有 Linux 与 Windows 注册实例可能共享持久化主机；其依赖、store 卷及清理假设不适用于全新的托管 VM。不改变故障切换或信任条件。
+
+## 影响
+
+预览以约 78 秒采样构建作业延迟换取更低的计算费用。生产 Cloudflare 延迟、镜像发布差异、未来构建增长及更广泛的成功率仍是可观测限制。不从本次单一实验外推每小时或每月节省。最终文件树不包含临时基准工作流及其安全测试；实验提交与链接的运行保留方法和证据。
+
+已执行的[针对性回归](../../../../scripts/preview-workflow.spec.ts) 固定托管路由、PR 触发器与权限、不可变完整构建、只恢复缓存、发布内容整理、受保护镜像检查及幂等评论。实际修改为自托管路由会使路由断言失败；恢复后全部三个测试通过。不改变模型可见运行时行为，因此不需要修改 Session 快照。

+## Comparison requirements
+
+A sizing experiment holds checkout SHA, lockfile, Node and pnpm versions, workspace build, and preview/VFS packing commands constant. Each runner starts without build outputs. Cold installs do not restore dependency caches; pnpm bootstrap files may already exist. Warm installs restore the same exact cache without prefix fallback. Record the actual runner image, CPU, RAM, disk, cache outcome, phase duration, exit status, and peak memory. GNU time maximum RSS reports a process maximum, not simultaneous aggregate memory across the build process tree.
+
+Calculate estimated gross compute as the sum of each completed job’s elapsed minutes rounded upward, multiplied by that runner’s rate. Include setup, cache restoration, cleanup, failures, and measurement-upload overhead. Report seed jobs separately. Queue delay is a latency observation, not executed job time. These estimates are not invoice totals; standard-runner included minutes and storage are separate.
+
+A build-only benchmark does not deploy, access Cloudflare credentials, or post pull-request comments. Its cost does not establish complete preview publication cost. Confirm the selected runner through the actual preview workflow before treating deployment latency and protected-image delivery as verified.
+
+<a id="publication-semantics"></a>
+
+## Publication semantics
+
+Runner selection does not alter pull-request events, per-PR cancellation, immutable installation, restore-only dependency caching, full workspace build, preview packing, sourcemap removal, or the preview page copied to the deployment root. Cloudflare uploads only the built site to the PR branch alias. The protected-image check requires HTTP 200, no transport content encoding, and gzip magic bytes; the URL comment remains idempotent. Dependabot and other PR authors remain on GitHub-hosted machines.

+## Dev Note
+
+The [runner decision](../../.agents/notes/implemented/process/2026-09-06-preview-hosted-runner-sizing.md) records measurements, cost estimates, and image/CPU variation. The build-only experiment does not verify production deployment.

+# PR 预览运行器规格
+
+[English](README.md) | 中文
+
+## 摘要
+
+[预览工作流](../workflows/build-preview-cloudflare.yml) 在标准 GitHub 托管 `ubuntu-24.04` 上构建 PR（Pull Request）预览。运行器规格选择比较完整作业成本，而非仅比较每分钟价格或核心数。
+
+## 目录
+
+- [比较要求](#comparison-requirements)
+- [发布语义](#publication-semantics)
+- [开发备注](#dev-note)
+
+<a id="comparison-requirements"></a>
+
+## 比较要求
+
+规格实验保持检出 SHA、锁文件、Node 与 pnpm 版本、工作区构建以及预览/VFS 打包命令一致。每个运行器启动时均无构建产物。冷安装不恢复依赖缓存，但 pnpm 引导安装文件可能已存在；热安装恢复同一个精确缓存，不使用前缀回退。记录实际运行器镜像、CPU、内存、磁盘、缓存结果、各阶段耗时、退出状态与内存峰值。GNU time 最大 RSS 表示进程最大值，而非构建进程树同时占用的内存总量。
+
+估算总计算费用时，将每个已完成作业的运行分钟数向上取整，乘以对应运行器费率后求和。纳入设置、缓存恢复、清理、失败及测量数据上传的开销。单独报告缓存预热作业。排队延迟属于延迟观测，不属于作业执行时间。这些估算不是账单总额；标准运行器的套餐内分钟数及存储另行计算。
+
+仅构建的基准测试不部署、不访问 Cloudflare 凭据，也不发布 PR 评论。其成本不能证明完整预览发布成本。在将部署延迟与受保护镜像交付视为已验证之前，须通过实际预览工作流确认所选运行器。
+
+<a id="publication-semantics"></a>
+
+## 发布语义
+
+运行器选择不改变 PR 事件、按 PR 取消、不可变安装、只恢复的依赖缓存、完整工作区构建、预览打包、sourcemap 删除，以及复制到部署根目录的预览页面。Cloudflare 仅将构建站点上传至 PR 分支别名。受保护镜像检查要求 HTTP 200、无传输内容编码及 gzip 魔数字节；URL 评论保持幂等。Dependabot 与其他 PR 作者仍使用 GitHub 托管机器。
+
+<a id="dev-note"></a>
+
+## 开发备注
+
+[运行器决策](../../.agents/notes/implemented/process/2026-09-06-preview-hosted-runner-sizing.zh.md) 记录测量、成本估算及镜像/CPU 差异。仅构建实验不验证生产部署。

 ## Decision
 
-Each of the three required Linux worker jobs, the independent native Windows job, and the `all checks passed` verdict job — which would otherwise stay queued on the failed pool even after every worker passed — resolves its runner pool through a repository variable, and the switch is split by platform so an outage on one platform does not retarget the other. The three Linux workers and the `all checks passed` verdict (whose `needs` are the required Linux workers and which runs on the `vm-backup` pool) resolve through `DSH_CI_FAILOVER_LINUX`; the native Windows job resolves through `DSH_CI_FAILOVER_WINDOWS`. Unset (normal), they run on the hosted enterprise pools. Set to `selfhosted` by any repository writer, the corresponding jobs retarget onto the in-house self-hosted pool: under `DSH_CI_FAILOVER_LINUX`, the Linux jobs and verdict move onto the `vm-backup` pool, snapshot concurrency drops to the shared-VM bound, and the hosted-path pnpm cache restores are skipped; under `DSH_CI_FAILOVER_WINDOWS`, the native Windows job moves onto the `dsh-win-ci` pool. Each switch is writer-manageable repository state, not a merge, so it works while every check is red. The in-house pools' readiness is continuously re-proven by the `serial / linux (self-hosted standby)` and `serial / windows (self-hosted standby)` lanes, which run the complete unsharded aggregates on every master push.

 `ci-master.yml` exempts exactly one event from `cancel-in-progress` (`${{ github.event_name != 'push' }}`), so one master push does not cancel the drill still running from the previous one. Each drill runs its complete unsharded aggregate with one gate worker, which takes longer than the interval between master merges; under unconditional cancellation a drill is superseded before reaching a verdict and the lane yields no readiness evidence for a responder to check.

 The decision belongs at workflow level because cancellation applies to the whole superseded run: a job-level `concurrency` group does not exempt its job. The negated form is load-bearing rather than cosmetic: naming `pull_request` alone would also stop cancelling `workflow_dispatch`, and each runner benchmark fans out to twelve larger runners for up to fifteen minutes inside this same group on master, so a re-dispatch would queue ahead of a drill instead of replacing a stale measurement. What bounds the cost is that a master push in `ci-master.yml` carries only `wine-apt-cache` and these two drills; the pull-request jobs live in the separate `ci.yml` (which does not see `push`), and the benchmarks are `workflow_dispatch`-gated within `ci-master.yml`. `scripts/ci-workflow.spec.ts` pins that push-reachable set — classifying by exact condition, since a negated event test mentions the event it excludes — so a new push-reachable job cannot quietly start accumulating uncancelled runs.
 
+### Release rehearsals share the Linux switch
+
+`DSH_CI_FAILOVER_LINUX=selfhosted` also routes the credential-free dependency-layout job and both dsh/vendor pack jobs onto `vm-backup` for eligible same-repository PRs and master pushes. Their [release rehearsal decision](2026-09-06-release-rehearsal-selfhosted.md) owns the stricter event eligibility and hosted manual dispatch. This coupling is intentional: keeping the variable set to save release minutes also keeps the eligible main-CI Linux jobs self-hosted. Clearing it returns both workloads to their hosted targets for subsequent runs; publication stays hosted regardless.

 ## Capacity during failover
 
-Six always-on instances absorb normal PR traffic (the pool's steady-state load is one serial standby job per master push, so failover capacity is effectively the full pool). If queues still build, register additional instances with an org registration token (org Settings → Actions → Runners → New runner). Clone an existing runner directory **excluding its identity files** — `rsync -a --exclude '.runner*' --exclude '.credentials*' --exclude '_diag' --exclude '_work' <src>/ <dst>/` (the globs also catch `.runner_migrated`/`.credentials_migrated`, which GitHub writes on migrated runners and which equally trigger the already-configured refusal) — then run `config.sh` (copying `.runner`/`.credentials` verbatim makes it refuse with "already configured"), and **start the listener**: `sudo ./svc.sh install ubuntu && sudo ./svc.sh start`. Registration alone leaves the runner offline; only a started service adds capacity. About a minute per instance.
+Capacity includes the master standby, main-CI jobs, and three release-rehearsal jobs for each eligible PR or master push while the Linux switch is set. The release workflows do not cancel running rehearsals when another run arrives, so overlapping refs can add sustained build, pack, and install load. Check current CPU, memory, disk, and queue pressure before extending self-hosted operation; extra registrations on this VM add scheduling slots, not machine resources. Do not infer spare capacity from the standby alone. When host resources permit extra registrations, use an org registration token (org Settings → Actions → Runners → New runner).

 这个决定必须放在工作流级：取消作用于被取代的整个运行，作业级 `concurrency` 组并不能豁免其所属作业。采用否定式写法而非仅指名 `pull_request`，是有实质作用的：后者会连 `workflow_dispatch` 一起停止取消，而每次运行器基准测试会在 master 上的同一并发组内同时占用 12 台大规格运行器、最长 15 分钟，届时重复派发会排在演练之前，而不是替换掉已过时的测量。成本之所以可控，是因为 `ci-master.yml` 中一次 master 推送只承载 `wine-apt-cache` 和这两条演练；拉取请求作业位于独立的 `ci.yml`（不监听 `push`），而基准测试在 `ci-master.yml` 内受 `workflow_dispatch` 门控。`scripts/ci-workflow.spec.ts` 会锁定这个推送可达集合——按条件精确匹配，因为否定式事件判断会包含它所排除的事件名——使新的推送可达作业无法悄悄开始累积未取消的运行。

 ## Decision
 
-The two jobs in [release.yml](../../../../.github/workflows/release.yml) and the pack job in [release-vendor.yml](../../../../.github/workflows/release-vendor.yml) select the existing self-hosted Linux pool only with the writer-controlled `DSH_CI_FAILOVER_LINUX` repository variable set to `selfhosted`. The selector requires the canonical repository and a non-Dependabot actor, then admits only master pushes or same-repository, non-fork PRs whose author is not Dependabot. Manual dispatch always selects `ubuntu-24.04`, as do all other rejected contexts. The [failover runbook](2026-07-26-ci-failover-runbook.md) continues to own the independent main-CI switches and standby operation; this note adds only release-rehearsal eligibility.

Release rehearsals intentionally share the Linux switch with main CI: enabling or disabling it routes both workloads, not releases independently. Unset remains the hosted default; hosted-minute savings occur only while an operator selects `selfhosted`, whether for an outage or a longer-running cost choice.
 
-The runner labels are `[self-hosted, linux, x64, vm-backup]`. Runner registrations share one VM, not independent machine capacity. Each job uses its runner-private temporary volume for Node compile cache and node-gyp headers before pnpm setup, and a pnpm setup destination qualified by run, attempt, and job. The persistent pnpm store stays outside checkout cleanup; only GitHub-hosted runners restore the remote store cache. Neither rehearsal workflow saves remote caches.

Each job uses its runner-private temporary volume for Node compile cache and node-gyp headers before pnpm setup, and a pnpm setup destination qualified by run, attempt, and job. `TMPDIR` also points to `runner.temp`, so temporary npm consumers stay outside the checkout but inside runner cleanup even when a killed process cannot execute `finally`. The persistent pnpm store stays outside checkout cleanup; only GitHub-hosted runners restore the remote store cache. Neither rehearsal workflow saves remote caches.
 
 Checkout explicitly cleans ignored and untracked output before immutable installation and the existing builds. Full tag history, pack concurrency, dependency checks, tarball verification, and artifact retention remain unchanged. The packed-install verifier creates a fresh consumer outside the checkout, installs tarballs with npm, removes inherited Node resolution hooks, and deletes the consumer in `finally`; a warm pnpm store cannot substitute workspace links or stale build output for a tarball payload. The [npm release decision](2026-08-10-npm-release-sequences.md) still owns release families and publication. Both manual publish workflows remain entirely hosted and gain no credentials or registry changes here.

 ## Problem
 
-The three required Linux worker jobs in [CI](../../../../.github/workflows/ci.yml) (`node 24 / static`, `node 24 / coverage`, `node 24 / snapshots and artifacts`) run on the hosted enterprise 32-core pools; the required verdict job that aggregates them (`all checks passed`) runs on standard `ubuntu-latest`; the independent native Windows job (`windows node 24 / native complete`) runs on the hosted `dsh-windows-2025-16core` larger runner. When the enterprise pools degrade — jobs queue indefinitely or the enterprise labels vanish — every open pull request becomes unmergeable, and the ordinary recovery of merging a fix is itself deadlocked behind the very required checks that cannot run. **Scope: two independent switches, one per platform.** `DSH_CI_FAILOVER_LINUX` recovers an enterprise Linux-pool outage (the three required Linux workers plus the `all checks passed` verdict); `DSH_CI_FAILOVER_WINDOWS` recovers a hosted Windows-pool outage (the native Windows job). A Linux-pool outage need not retarget the native Windows job and vice versa. The verdict's other required dependencies (`node-compat`, `python-sdk`, `windows`) stay on standard hosted runners by design (the portable boundary); in a broader GitHub-hosted capacity failure that also takes out the standard pools, those dependencies still block `all checks passed`. An outage therefore needs a switch any responder with repository write access can throw without merging anything.

An outage therefore needs a switch any responder with repository write access can throw without merging anything.
 
 ## Decision
 
-Each of the three required Linux worker jobs, the independent native Windows job, and the `all checks passed` verdict job — which would otherwise stay queued on the failed pool even after every worker passed — resolves its runner pool through a repository variable, and the switch is split by platform so an outage on one platform does not retarget the other. The three Linux workers and the `all checks passed` verdict (whose `needs` are the required Linux workers and which runs on the `vm-backup` pool) resolve through `DSH_CI_FAILOVER_LINUX`; the native Windows job resolves through `DSH_CI_FAILOVER_WINDOWS`. Unset (normal), they run on the hosted enterprise pools. Set to `selfhosted` by any repository writer, the corresponding jobs retarget onto the in-house self-hosted pool: under `DSH_CI_FAILOVER_LINUX`, the Linux jobs and verdict move onto the `vm-backup` pool, snapshot concurrency drops to the shared-VM bound, and the hosted-path pnpm cache restores are skipped; under `DSH_CI_FAILOVER_WINDOWS`, the native Windows job moves onto the `dsh-win-ci` pool. Each switch is writer-manageable repository state, not a merge, so it works while every check is red. The in-house pools' readiness is continuously re-proven by the `serial / linux (self-hosted standby)` and `serial / windows (self-hosted standby)` lanes, which run the complete unsharded aggregates on every master push.

Each drill runs its complete unsharded aggregate with one gate worker, which takes longer than the interval between master merges; under unconditional cancellation a drill is superseded before reaching a verdict and the lane yields no readiness evidence for a responder to check.

The workspaces and the pnpm store must both live on a ReFS volume (`F:`): the Windows installs pass `--package-import-method=clone` on ReFS, which needs that volume layout and the `@reflink/reflink` native module that the system corepack pnpm carries (see [the Windows ReFS store note](../../archived/process/2026-08-30-windows-refs-store-block-clone-install.md)); a rebuilt runner without this layout fails the Windows build gates with TS6231.

The general-purpose Windows workspaces and pnpm store must both live on a ReFS volume (`F:`): those installs pass `--package-import-method=clone` on ReFS, which needs that volume layout and the `@reflink/reflink` native module that the system corepack pnpm carries (see [the Windows ReFS store note](../../archived/process/2026-08-30-windows-refs-store-block-clone-install.md)); a rebuilt runner without this layout fails the Windows build gates with TS6231. Check the latest `serial / windows (self-hosted standby)` run before switching: a green standby verifies the pool can execute `check:ci:windows-complete` end-to-end.

This proposal covers only Python runtime builds.
 
 The [read-only prerequisite probe](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012679056) found native Windows x64, Python 3.14.7 with venv/ensurepip, and enabled Developer Mode, but no Python toolcache. Linux lacked Docker, which both manylinux steps require. These observations permit a Windows-only experiment, not a claim that the runtime build passes.
 
 ## Proposal
 
-Route only the Windows x64 target in [the runtime workflow](../../../../.github/workflows/build-exe-for-python-sdk.yml) to the persistent pool when `inputs.ci && !inputs.release`, the repository is the canonical repository, and the event is either a same-repository non-fork, non-Dependabot PR or a master push. `DSH_CI_FAILOVER_WINDOWS=selfhosted` enables this routing; an unset or different value keeps the lane hosted. Release/manual builds, other events, Linux/macOS targets, planning, and the SDK-wheel job remain hosted. The implementation is pending native runtime validation.

 ## Alternatives considered
 
+**An independent Python failover switch.** Rejected for this shared host: reusing `DSH_CI_FAILOVER_WINDOWS` lets responders recover the platform with one switch and adds no variable. The trade-off is coupled placement: enabling native Windows failover also adds eligible Python runtime builds and their cold private-tool/cache setup load to the same host; clearing it returns both workloads to hosted pools.

 **Cold setup-python with a private toolcache.** Rejected: the concrete Python 3.10.11 [Windows release installer](https://github.com/actions/python-versions/blob/98e79473eb342d6f43487a289ca633620404742e/installers/win-setup-template.ps1#L21-L70) removes matching machine/current-user installation records and installs for all users. A private directory does not isolate that registry state.
 
 **Administrator-preprovisioned Python 3.10.** Viable with enforced cache-hit-only use and private dependency environments, but the measured pool does not supply it. Portable uv avoids requiring a host installation change.

+**独立的 Python 故障切换开关。** 对这台共享主机不采用：复用 `DSH_CI_FAILOVER_WINDOWS` 让响应者用一个开关恢复整个平台，不新增变量。代价是部署位置相互绑定：启用原生 Windows 故障切换也会把符合条件的 Python runtime 构建及其私有工具/缓存冷启动负载加到同一主机上；清除开关则让两类工作负载都回到托管池。

+# Agent Note: The system prompt is surface node 0
+
+Status: proposed
+
+English | [中文](2026-09-02-system-prompt-as-surface-node.zh.md)
+
+## Problem
+
+The system prompt has a different durable representation from every other message the model reads. Conversation messages are surface events (`user/message`, `assistant/message`, `tool/result`) folded in seq order by `Session.deriveMessages()`; the system prompt is the `system` field of the log-only `request/header` snapshot, and each DeepSeek serializer prepends it as wire message 0 (`serializeRequest`, `serializeRequestWithImages`). The [reconstructable-requests Agent Note](../../implemented/architecture/2026-07-05-reconstructable-requests.md) made both halves durable, but it left one model-visible fact with two homes: the surface owns the messages, the header owns the message in front of them.
+
+That split forces every reader of "what did the model see" to join two sources. The compaction summarizer (`buildSummarizationInput`) copies `header.system` in front of the region's derived messages; `dsh-token-meter` estimates the system prompt from the header while pricing every other message from the surface; the Web request-prompt card, the trajectory view, and the snapshot normalizer's `{{system}}` placeholder each read the header on their own. The loop's change detection is also split: `headerEquals` compares `system` byte-for-byte beside `config` and `tools`, so a prompt change and a tool change are indistinguishable in the log (`request/header` reason `change`) even though they are different operations on the conversation.
+
+The split also blocks the next step. A model that accepts a mid-conversation `system` message as a prompt replacement needs the harness to append a system-role message to history; with the prompt living in the header there is no surface representation to append, and the header would have to be frozen by special case. The [in-history replacement proposal](../feature/2026-09-02-in-history-system-prompt-replacement.md) depends on this note.
+
+## Proposal
+
+Move the system prompt onto the surface. It becomes an ordinary surface event, `system/message`, and every prompt lifecycle operation is one of the two existing `SurfaceOp` variants applied to that event type. The wire request does not change: the surface fold yields the same message list the serializers already build today, with the system message first.
+
+### The event
+
+`system/message` joins `SurfaceEventType` beside `user/message`, `assistant/message`, and `tool/result`. Its payload mirrors `tool/result`: `{ turn, step, message }`, where `message` is a `Message` with `role: 'system'`, exactly one text block holding the rendered prompt, and source `{ kind: 'plugin', plugin: '@deepseek-ai/dsh-system-prompt' }`. `deriveEventMessage` projects it verbatim, so `deriveMessages()` returns the system message at its surface position and both DeepSeek serializers, which already pass a `role: 'system'` history message through unchanged, emit it as wire message 0. `EpochHeader.system` is removed; the header keeps `config`, `adapterDefaults`, and `tools`.
+
+### The operations
+
+| Situation | Surface operation |
+|---|---|
+| First request of a session with a non-empty rendered prompt | append `system/message` as surface node 0, before the first `user/message` of the step |
+| Rendered prompt differs from the prompt at node 0 | replace node 0: `surfaceOp: { op: 'replace', start: <seq of node 0>, end: <same> }`, `sourceEventSeqs: [<seq of node 0>]` |
+| Rendered prompt is empty on the first request | no system node; a later non-empty prompt appends node 0 when the surface has no system node yet |
+
+Replacing node 0 is today's head rewrite expressed on the surface: the provider prefix changes from the first token, the log records the shadowed node through `sourceEventSeqs`, and `replaceGeneration` advances exactly as it does for a compaction replacement, so the loop's existing `startsSeries` detection (`requestSurfaceGeneration !== surfaceGeneration`) covers the prompt change without a `system` comparison in `headerEquals`. `request/header` keeps reasons `initial`, `resume`, `change`, and `series`; `change` now means config or tools changed.
+
+### Ownership in the loop
+
+`dsh-agent-loop` owns a `SystemPromptProjection` beside `RuntimeContextProjection` in `runtime-context.ts`. It restores the current system node from the log (the latest surviving `system/message` on the surface), follows `session/event` for new system nodes and for replacements whose `sourceEventSeqs` shadow the retained one, and returns the uncommitted append or replace intent when the rendered prompt differs. `turn()` commits that intent immediately before the step's `user/message` events, so the log order is the wire order. `step()` no longer passes `system` to `buildRequest`; the request is `header.config` plus `deriveMessages()` plus `header.tools`. The `dsh-agent-loop/invariant` companion keeps comparing the rebuilt request against the frozen one, now with the system message inside `messages`. `docs/architecture.md` records the new loop step order: claim, assemble, project system prompt, project runtime context, pre-step, commit system node, commit user messages, build request.
+
+### Consumers retargeted
+
+| Consumer | Today | After |
+|---|---|---|
+| DeepSeek serializers (`serializeRequest`, `serializeRequestWithImages`) | prepend `options.system` | serialize `options.messages` only; `GenerateOptions.system` remains for direct one-shot callers such as the summarizer and title providers |
+| `compaction-basic` `buildSummarizationInput` | `header.system` + region messages | node 0's derived message + region messages, still a genuine prefix of the routed request |
+| `compaction-basic` `selectCompactableRange` | head-anchored at `surfaceNodes[0]` | anchored at the first non-system node; node 0 is never inside a compaction range |
+| `dsh-token-meter` system estimate | `header.system` length | the system node is priced like every other surface node; the context breakdown labels it by its source plugin |
+| Web request-prompt card, trajectory request-header node, request inspection | read `header.system` | read the `system/message` node; the card keeps its collapsed inspectable presentation and is never a chat bubble |
+| Snapshot normalizer `{{system}}` placeholder, plan-mode tests asserting `header.system` | header | the system node's text |
+| TypeScript and Python SDK expected outputs | no system event | include the `system/message` event |
+| Human transcript projections (`isAppendSurfaceEvent` readers) | no system events | skip `system/message`; it is model history, not conversation |
+
+`RuntimeContextProjection` and `SystemPromptProjection` are symmetric: both watch owned surface nodes and their shadowing through `sourceEventSeqs`, and both hand the loop an uncommitted message that `turn()` commits. The difference is the role and the operation set — runtime context appends user-role snapshots only, the system prompt appends once and then replaces.
+
+## Alternatives considered
+
+**Keep `header.system` and add `system/message` only for updates.** Two homes for one fact: every consumer above would read the header for message 0 and the surface for later messages, and the loop would need a special case that ignores `system` in `headerEquals` while a surface system node exists. Rejected because the point of the change is one representation.
+
+**A dedicated log-only `system-prompt/change` event that rewrites the header.** Preserves the header as the home of the prompt and records changes as their own event kind, but still cannot express a system message inside history, so the in-history proposal would need a second mechanism anyway. Rejected.
+
+**Synthesize the system message inside the adapter from consecutive headers.** The adapter is stateless per request and never sees the log; a wire history that depends on adapter state is not reconstructable from the surface fold. Rejected.
+
+**Express the prompt as a `user/message` snapshot like runtime context.** Reuses an existing event type but sends the wrong role, so a model that treats a system message as authoritative would not. Rejected.
+
+## Acceptance criteria
+
+- `SurfaceEventType` contains `system/message`; `deriveEventMessage` projects it; `Session.append('system/message', …)` requires a `SurfaceIntent` like the other surface events.
+- `EpochHeader` has no `system` field; `headerEquals` compares `config`, `adapterDefaults`, and `tools` only.
+- A first request with a non-empty rendered prompt appends `system/message` as surface node 0 before the step's first `user/message`; a changed prompt replaces node 0 with `sourceEventSeqs` naming the shadowed node; an unchanged prompt appends nothing.
+- The DeepSeek wire request for every loop step is byte-identical to today's for the same session history: system first, then the folded conversation.
+- Compaction never selects node 0; the summarizer's replayed prefix starts with node 0's derived message.
+- `dsh-token-meter`, the Web request-prompt card, trajectory and inspection views, the snapshot normalizer, plan-mode tests, and both SDK expected outputs read the system node; the `dsh-agent-loop/invariant` companion rebuilds requests with the system message inside `messages`.
+- Keyless recorded snapshots that exercise a mid-session prompt change (plan mode entering and leaving) show a replaced node 0 instead of a `request/header` `change`.
+- `docs/architecture.md`, the `dsh-agent-loop`, `dsh-session`, `dsh-system-prompt`, `dsh-compaction-basic`, and `dsh-token-meter` READMEs, and the reconstructable-requests Agent Note describe the surface node as the home of the system prompt.
+
+## Risks
+
+- Every reader of `header.system` moves in one change; a missed reader fails at compile time because the field is gone, which is the intended failure mode.
+- Compaction region selection gains an invariant (node 0 is never compacted). A compaction provider other than `compaction-basic` that anchors at `surfaceNodes[0]` would shadow the prompt; the `dsh-session` surface manager rejects a replacement whose range covers surface node 0 while node 0 is a `system/message` unless the replacing event is itself a `system/message` covering exactly that node, so the invariant is enforced where the operation happens, not only in the shipped provider. System nodes at later positions carry no such protection: a compaction range may shadow them.
+- Replacing node 0 advances `replaceGeneration`, which today means "compaction happened" to some readers; those readers switch to inspecting the replacement event's type.
+- Recorded snapshot fixtures whose logs contain `header.system` are re-recorded; the fixtures, not the normalizer, change.

+# Agent Note: 系统提示词是 surface 的第 0 号节点
+
+Status: proposed
+
+[English](2026-09-02-system-prompt-as-surface-node.md) | 中文
+
+## Problem
+
+系统提示词的持久化表示与模型读到的其他所有消息都不同。对话消息是 surface 事件（`user/message`、`assistant/message`、`tool/result`），由 `Session.deriveMessages()` 按 seq 顺序折叠；系统提示词则是仅记日志的 `request/header` 快照中的 `system` 字段，每个 DeepSeek 序列化器把它前置为协议消息 0（`serializeRequest`、`serializeRequestWithImages`）。[可重建请求 Agent Note](../../implemented/architecture/2026-07-05-reconstructable-requests.zh.md) 让两半都成为持久数据，却让一个模型可见的事实拥有两个归属：surface 拥有消息，header 拥有排在这些消息之前的那条消息。
+
+这种拆分迫使每个想知道「模型看到了什么」的读取方都要合并两个来源。压缩摘要器（`buildSummarizationInput`）把 `header.system` 复制到区域派生消息之前；`dsh-token-meter` 从 header 估算系统提示词，却从 surface 为其他每条消息计价；Web 请求提示词卡片、轨迹视图和快照归一化器的 `{{system}}` 占位符各自单独读取 header。循环的变更检测同样被拆开：`headerEquals` 在 `config` 和 `tools` 旁边逐字节比较 `system`，因此提示词变更与工具变更在日志中无法区分（`request/header` 的 reason 都是 `change`），尽管它们是对对话的两种不同操作。
+
+这种拆分还阻塞了下一步。一个把对话中途的 `system` 消息当作提示词替换来接受的模型，需要 harness 向历史追加一条 system 角色消息；当提示词住在 header 里时，没有可追加的 surface 表示，header 也只能靠特例被冻结。[历史内替换提案](../feature/2026-09-02-in-history-system-prompt-replacement.zh.md) 依赖本 Agent Note。
+
+## Proposal
+
+把系统提示词搬到 surface 上。它成为一个普通的 surface 事件 `system/message`，提示词生命周期中的每个操作都是对该事件类型施加现有两种 `SurfaceOp` 变体之一。协议请求不变：surface 折叠产出的消息列表与序列化器今天构建的完全相同，系统消息在最前面。
+
+### 事件
+
+`system/message` 加入 `SurfaceEventType`，与 `user/message`、`assistant/message`、`tool/result` 并列。它的载荷与 `tool/result` 对称：`{ turn, step, message }`，其中 `message` 是 `role: 'system'` 的 `Message`，恰好一个文本块承载渲染后的提示词，source 为 `{ kind: 'plugin', plugin: '@deepseek-ai/dsh-system-prompt' }`。`deriveEventMessage` 逐字投影它，因此 `deriveMessages()` 在其 surface 位置返回系统消息，而两个 DeepSeek 序列化器本已原样透传 `role: 'system'` 的历史消息，会把它作为协议消息 0 发出。`EpochHeader.system` 被移除；header 保留 `config`、`adapterDefaults` 和 `tools`。
+
+### 操作
+
+| 情形 | surface 操作 |
+|---|---|
+| 会话首个请求且渲染后的提示词非空 | 追加 `system/message` 作为 surface 第 0 号节点，位于该步骤首条 `user/message` 之前 |
+| 渲染后的提示词与第 0 号节点不同 | 替换第 0 号节点：`surfaceOp: { op: 'replace', start: <第 0 号节点的 seq>, end: <同一值> }`，`sourceEventSeqs: [<第 0 号节点的 seq>]` |
+| 首个请求时渲染后的提示词为空 | 没有系统节点；之后出现非空提示词且 surface 尚无系统节点时，追加为第 0 号节点 |
+
+替换第 0 号节点就是今天的头部重写在 surface 上的表达：提供方前缀从第一个 token 起改变，日志通过 `sourceEventSeqs` 记录被遮蔽的节点，`replaceGeneration` 与压缩替换时一样推进，因此循环现有的 `startsSeries` 检测（`requestSurfaceGeneration !== surfaceGeneration`）无需在 `headerEquals` 中比较 `system` 即可覆盖提示词变更。`request/header` 保留 `initial`、`resume`、`change`、`series` 四种 reason；`change` 现在表示 config 或 tools 变更。
+
+### 循环中的归属
+
+`dsh-agent-loop` 在 `runtime-context.ts` 中与 `RuntimeContextProjection` 并列拥有一个 `SystemPromptProjection`。它从日志恢复当前系统节点（surface 上最新存活的 `system/message`），跟随 `session/event` 观察新的系统节点以及 `sourceEventSeqs` 遮蔽了所保留节点的替换，并在渲染后的提示词不同时返回未提交的追加或替换意图。`turn()` 紧接在该步骤的 `user/message` 事件之前提交该意图，因此日志顺序即协议顺序。`step()` 不再向 `buildRequest` 传递 `system`；请求由 `header.config`、`deriveMessages()` 和 `header.tools` 构成。`dsh-agent-loop/invariant` 伴随组件继续把重建的请求与冻结的请求比较，只是系统消息现在位于 `messages` 内。`docs/architecture.md` 记录新的循环步骤顺序：领取、装配、投影系统提示词、投影运行时上下文、pre-step、提交系统节点、提交用户消息、构建请求。
+
+### 消费方迁移
+
+| 消费方 | 现状 | 变更后 |
+|---|---|---|
+| DeepSeek 序列化器（`serializeRequest`、`serializeRequestWithImages`） | 前置 `options.system` | 只序列化 `options.messages`；`GenerateOptions.system` 为摘要器、标题提供方等直接单次调用方保留 |
+| `compaction-basic` 的 `buildSummarizationInput` | `header.system` + 区域消息 | 第 0 号节点的派生消息 + 区域消息，仍是已路由请求的真实前缀 |
+| `compaction-basic` 的 `selectCompactableRange` | 锚定在头部 `surfaceNodes[0]` | 锚定在首个非系统节点；第 0 号节点永不落入压缩范围 |
+| `dsh-token-meter` 的系统提示词估算 | `header.system` 长度 | 系统节点与其他每个 surface 节点一样计价；上下文明细按其 source 插件标注 |
+| Web 请求提示词卡片、轨迹请求 header 节点、请求检视 | 读取 `header.system` | 读取 `system/message` 节点；卡片保持折叠可检视的呈现，永不作为聊天气泡 |
+| 快照归一化器的 `{{system}}` 占位符、断言 `header.system` 的 plan-mode 测试 | header | 系统节点的文本 |
+| TypeScript 与 Python SDK 期望输出 | 没有系统事件 | 包含 `system/message` 事件 |
+| 人类转录投影（`isAppendSurfaceEvent` 的读取方） | 没有系统事件 | 跳过 `system/message`；它是模型历史，不是对话 |
+
+`RuntimeContextProjection` 与 `SystemPromptProjection` 是对称的：两者都通过 `sourceEventSeqs` 观察自己拥有的 surface 节点及其被遮蔽的情况，都把一条未提交的消息交给循环由 `turn()` 提交。区别在于角色与操作集——运行时上下文只追加 user 角色快照，系统提示词追加一次之后只做替换。
+
+## Alternatives considered
+
+**保留 `header.system`，只为更新添加 `system/message`。** 一个事实两个归属：上述每个消费方都要从 header 读消息 0、从 surface 读后续消息，循环还需要一个在 surface 存在系统节点时让 `headerEquals` 忽略 `system` 的特例。被否决，因为本次变更的目的就是单一表示。
+
+**用专门的仅记日志事件 `system-prompt/change` 重写 header。** 保留 header 作为提示词归属，并把变更记录为独立事件种类，但仍无法表达历史内部的系统消息，历史内替换提案还是需要第二套机制。被否决。
+
+**在适配器内根据相邻 header 合成系统消息。** 适配器逐请求无状态且从不接触日志；依赖适配器状态的协议历史无法从 surface 折叠重建。被否决。
+
+**像运行时上下文那样用 `user/message` 快照表达提示词。** 复用了现有事件类型，却发送了错误的角色，因此把系统消息视为权威的模型不会这样对待它。被否决。
+
+## Acceptance criteria
+
+- `SurfaceEventType` 包含 `system/message`；`deriveEventMessage` 投影它；`Session.append('system/message', …)` 与其他 surface 事件一样要求 `SurfaceIntent`。
+- `EpochHeader` 没有 `system` 字段；`headerEquals` 只比较 `config`、`adapterDefaults` 和 `tools`。
+- 渲染后的提示词非空的首个请求在该步骤首条 `user/message` 之前追加 `system/message` 作为 surface 第 0 号节点；提示词变更时以指明被遮蔽节点的 `sourceEventSeqs` 替换第 0 号节点；提示词不变时不追加任何内容。
+- 对同一会话历史，每个循环步骤的 DeepSeek 协议请求与今天逐字节一致：系统消息在先，随后是折叠后的对话。
+- 压缩永不选中第 0 号节点；摘要器回放的前缀以第 0 号节点的派生消息开头。
+- `dsh-token-meter`、Web 请求提示词卡片、轨迹与检视视图、快照归一化器、plan-mode 测试以及两个 SDK 的期望输出都读取系统节点；`dsh-agent-loop/invariant` 伴随组件重建请求时系统消息位于 `messages` 内。
+- 演练会话中途提示词变更（进入与退出 plan 模式）的无密钥录制快照显示被替换的第 0 号节点，而不是 `request/header` 的 `change`。
+- `docs/architecture.md`、`dsh-agent-loop`、`dsh-session`、`dsh-system-prompt`、`dsh-compaction-basic`、`dsh-token-meter` 的 README 以及可重建请求 Agent Note 都把 surface 节点描述为系统提示词的归属。
+
+## Risks
+
+- `header.system` 的每个读取方在一次变更中迁移；遗漏的读取方因字段消失而在编译期失败，这正是预期的失败方式。
+- 压缩范围选择新增一条不变量（第 0 号节点永不被压缩）。除 `compaction-basic` 以外、锚定在 `surfaceNodes[0]` 的压缩提供方会遮蔽提示词；`dsh-session` 的 surface 管理器拒绝在第 0 号节点是 `system/message` 时覆盖第 0 号节点的替换，除非替换事件本身是恰好覆盖该节点的 `system/message`，因此不变量在操作发生处被强制，而不只在随发的提供方中。位于更后位置的系统节点没有此类保护：压缩范围可以遮蔽它们。
+- 替换第 0 号节点会推进 `replaceGeneration`，今天有些读取方把它理解为「发生了压缩」；这些读取方改为检查替换事件的类型。
+- 日志中包含 `header.system` 的录制快照 fixture 需要重新录制；改变的是 fixture，而不是归一化器。

+# Agent Note: In-history system prompt replacement for cache-stable prompt changes
+
+Status: proposed
+
+English | [中文](2026-09-02-in-history-system-prompt-replacement.zh.md)
+
+## Problem
+
+Every system prompt change costs the whole provider prefix cache. The loop renders the prompt on every step; when the bytes differ — a plan-mode section entering or leaving, a skill or tool guidance section registering, an agent-scoped persona shadow, a changed `{{model}}` variable — the request's message 0 changes and the DeepSeek context cache misses from the first token. Long agentic sessions pay this repeatedly, and the [runtime-context snapshot design](../../archived/feature/2026-07-30-current-sandbox-policy-context.md) exists precisely because moving a changing fact out of the prompt was the only way to keep the prefix stable.
+
+A DeepSeek model, provided as an unpublished model fact for this proposal, removes that constraint: it accepts a `system` message at any position of the conversation and treats the latest one as the complete effective system prompt, replacing the leading one. Tool schemas remain part of the cached prefix, so a tool-set change still invalidates the cache. With that model the harness can append the new prompt after the cached history instead of rewriting message 0, and the prefix stays warm.
+
+The harness has the representation for this only after the [system prompt is surface node 0](../architecture/2026-09-02-system-prompt-as-surface-node.md): a prompt change is then an operation on `system/message` surface nodes, and the choice between "replace node 0" and "append a new node" is a per-model decision.
+
+## Proposal
+
+For a model route that declares the capability, the loop appends a new `system/message` surface node instead of replacing node 0 when the rendered prompt changes and the prefix would otherwise survive. Everything else in the [surface-node design](../architecture/2026-09-02-system-prompt-as-surface-node.md) is unchanged: the event type, the projection owner, the serializers, and the presentation.
+
+### Capability
+
+The DeepSeek adapter's catalog model gains a validated optional field, `systemPromptUpdate`, with the single accepted value `'in-history'`; absence means the model needs message 0 rewritten. The adapter surfaces it on `LlmResolvedModelInfo` and `prepareCall()` returns it beside `context.contextWindow`, so the loop reads it from the same registration-bound metadata it already consumes. No default catalog entry declares it until the model is released; a deployment enables it through the `models` list in `cordis.yml`. Models without the field — including every current default entry and every `dsh-llm-pi-ai` route — keep the replace-node-0 behaviour exactly.
+
+### The decision rule
+
+`SystemPromptProjection` tracks the **effective prompt**: the text of the latest surviving `system/message` on the surface (node 0 when no later system node exists). When the rendered prompt differs from the effective prompt:
+
+| Route capability | Prefix state | Operation |
+|---|---|---|
+| none | any | replace node 0 |
+| `in-history` | the current request series continues (no compaction since the last request, no tools or config change) | append a new `system/message` before the step's `user/message` events |
+| `in-history` | a new series starts (compaction replaced the surface, or `request/header` records a `change` for tools or config) and no mid-history system node survives | replace node 0 with the current prompt |
+| `in-history` | a new series starts but a mid-history system node survives | append a new `system/message`; node 0 stays as it is |
+
+The third row exists because a series start already costs the cache; folding the prompt back into node 0 keeps the history short. The fourth row exists because the surface has no delete operation: replacing node 0 while a later system node survives would leave the model reading the later, stale node as authoritative, so the loop appends instead. In-history mode never rewrites node 0 while any later system node survives.
+
+Resume follows the mid-session rule. A new loop instance restores the effective prompt from the log and, when the freshly rendered prompt differs, appends — the provider cache may still be warm across a process boundary, and the `resume` header is not a series start.
+
+### Presentation and accounting
+
+A mid-history `system/message` uses the same collapsed request-prompt inspection card as node 0, labelled as a prompt update at its position in the request; it is never a chat bubble, transcript projections skip it, and SDK projections expose it as a typed event. `dsh-token-meter` prices it like any other surface node, so the per-step context breakdown shows the accumulated cost of retained prompt versions until compaction shadows them. `cacheReadTokens` on the following `assistant/message` usage is the observable effect: for a capable route the value covers the prefix through the last cached message; for a non-capable route it drops to the shared-prefix detection floor.
+
+### Verification plan
+
+- Unit tests in `dsh-agent-loop` for the projection: append on a mid-series change, replace on a series start without surviving mid-history nodes, append on a series start with one, append on resume, no operation when unchanged, and replace-only behaviour for a route without the capability.
+- Unit tests in `dsh-llm-deepseek` for catalog validation (`systemPromptUpdate` accepts `'in-history'` only) and for `prepareCall()` surfacing the field.
+- A keyless recorded snapshot under `snapshots/` whose composition declares the capability on the mock route and toggles plan mode mid-session, pinning the appended `system/message` and the untouched node 0; TypeScript and Python SDK expected outputs include the appended event.
+- A real-API e2e that runs two steps with a prompt change against a capable route and asserts that the second request's `cacheReadTokens` is at least the first request's prompt token count. It resolves its route from the standard credential and base-URL mechanism and self-skips when no capable route is configured.
+
+## Alternatives considered
+
+**Send only the changed sections as a delta.** The model treats the latest system message as the complete prompt, so a delta would silently drop every unchanged section. Rejected on the model contract.
+
+**Enable in-history mode by plugin config instead of a model capability.** A deployment flag could pair a non-capable model with appended system messages, which such a model would read as ordinary history at best. The capability belongs to the route that honours it; the adapter catalog already carries per-model capacities. Rejected.
+
+**Always append, never re-baseline.** One rule, but node 0 would stay stale for the life of the session and every request after compaction would carry the stale head plus the replacement. Re-baselining at a series start costs nothing extra because the cache is already lost there. Rejected.
+
+**Re-baseline on every resume.** Accepts one cache miss per process restart for a simpler resume path. The cache persists across restarts for hours to days, and the log already carries what resume needs. Rejected.
+
+**Place the system message after the step's user messages.** Both positions sit after the cached prefix, but the model then reads the instructions after the input it must apply them to; system-before-user matches the leading position's ordering. Rejected.
+
+## Acceptance criteria
+
+- `DeepSeekCatalogModel.systemPromptUpdate` is validated at load, exposed through `LlmResolvedModelInfo`, and returned by `prepareCall()`; a misspelt value fails at load.
+- On a capable route a mid-series prompt change appends `system/message` before the step's `user/message` events and node 0 is unchanged; on a non-capable route the same change replaces node 0.
+- On a capable route a series start with no surviving mid-history system node replaces node 0; with a surviving one it appends.
+- A resumed loop instance whose rendered prompt differs appends on a capable route.
+- The recorded snapshot and both SDK expected outputs pin the appended event; the e2e asserts the cache-hit inequality when a capable route is configured and skips otherwise.
+- The `dsh-llm-deepseek`, `dsh-agent-loop`, and `dsh-system-prompt` READMEs document the capability, the decision rule, and the KV Cache effect; `docs/config-catalog.md` lists the field.
+
+## Risks
+
+- The model contract is unpublished; the note records it as provided. If the released model narrows it (for example, honouring only the latest system message within a bounded window), the decision rule needs a re-baseline trigger beyond series starts.
+- Retained prompt versions accumulate in history until compaction shadows them. Each version costs its tokens on every request in the series; a deployment whose prompt changes on most steps would be better served by moving that fact into runtime context.
+- A proxy that rewrites or reorders system messages breaks the replacement semantics silently; the e2e's cache-hit assertion is the detector.

+# Agent Note: 历史内系统提示词替换，实现缓存稳定的提示词变更
+
+Status: proposed
+
+[English](2026-09-02-in-history-system-prompt-replacement.md) | 中文
+
+## Problem
+
+每一次系统提示词变更都要付出整个提供方前缀缓存的代价。循环在每个步骤渲染提示词；一旦字节不同——plan 模式片段进入或退出、某个 skill 或工具指引片段完成注册、agent 作用域的 persona 遮蔽、`{{model}}` 变量改变——请求的消息 0 随之改变，DeepSeek 上下文缓存从第一个 token 起失效。长时间的 agent 会话反复为此付费，而[运行时上下文快照设计](../../archived/feature/2026-07-30-current-sandbox-policy-context.md)之所以存在，正是因为把会变化的事实移出提示词是保持前缀稳定的唯一办法。
+
+一个 DeepSeek 模型——作为本提案所依据的未公开模型事实——移除了这一限制：它接受对话任意位置的 `system` 消息，并把最新一条视为完整的有效系统提示词，替换最前面那条。工具 schema 仍属于被缓存的前缀，因此工具集变更仍会使缓存失效。有了这样的模型，harness 可以把新提示词追加到已缓存的历史之后而不是重写消息 0，前缀就能保持热态。
+
+只有在[系统提示词成为 surface 第 0 号节点](../architecture/2026-09-02-system-prompt-as-surface-node.zh.md)之后，harness 才拥有实现这一点的表示：提示词变更随之成为对 `system/message` surface 节点的操作，而「替换第 0 号节点」与「追加新节点」之间的选择是逐模型的决定。
+
+## Proposal
+
+对于声明了该能力的模型路由，当渲染后的提示词变化且前缀本可存活时，循环追加一个新的 `system/message` surface 节点而不是替换第 0 号节点。[surface 节点设计](../architecture/2026-09-02-system-prompt-as-surface-node.zh.md)中的其他一切不变：事件类型、投影的拥有者、序列化器和呈现。
+
+### 能力
+
+DeepSeek 适配器的目录模型新增一个经校验的可选字段 `systemPromptUpdate`，唯一接受的值是 `'in-history'`；缺省表示该模型需要重写消息 0。适配器把它暴露在 `LlmResolvedModelInfo` 上，`prepareCall()` 在 `context.contextWindow` 旁边返回它，因此循环从它已经消费的同一份注册绑定元数据中读取。在该模型发布之前，没有默认目录条目声明它；部署方通过 `cordis.yml` 的 `models` 列表启用。没有该字段的模型——包括当前所有默认条目和所有 `dsh-llm-pi-ai` 路由——完全保持替换第 0 号节点的行为。
+
+### 决策规则
+
+`SystemPromptProjection` 跟踪**有效提示词**：surface 上最新存活的 `system/message` 的文本（不存在更后的系统节点时即第 0 号节点）。当渲染后的提示词与有效提示词不同时：
+
+| 路由能力 | 前缀状态 | 操作 |
+|---|---|---|
+| 无 | 任意 | 替换第 0 号节点 |
+| `in-history` | 当前请求序列延续（上次请求以来没有压缩，tools 或 config 没有变更） | 在该步骤的 `user/message` 事件之前追加新的 `system/message` |
+| `in-history` | 新序列开始（压缩替换了 surface，或 `request/header` 记录了 tools 或 config 的 `change`）且没有历史中途的系统节点存活 | 用当前提示词替换第 0 号节点 |
+| `in-history` | 新序列开始但有历史中途的系统节点存活 | 追加新的 `system/message`；第 0 号节点保持原样 |
+
+第三行存在，是因为序列开始已经付出了缓存代价；把提示词折回第 0 号节点能让历史保持简短。第四行存在，是因为 surface 没有删除操作：在更后的系统节点仍存活时替换第 0 号节点，会让模型把更后、已过时的节点当作权威，所以循环改为追加。历史内模式在任何更后的系统节点存活期间永不重写第 0 号节点。
+
+恢复遵循会话中途的规则。新的循环实例从日志恢复有效提示词，当新渲染的提示词不同时执行追加——提供方缓存在进程边界之后可能仍是热的，且 `resume` header 不是序列开始。
+
+### 呈现与记账
+
+历史中途的 `system/message` 使用与第 0 号节点相同的折叠请求提示词检视卡片，在请求中的对应位置标注为提示词更新；它永不作为聊天气泡，转录投影跳过它，SDK 投影把它暴露为带类型的事件。`dsh-token-meter` 像对待其他任何 surface 节点一样为它计价，因此逐步骤的上下文明细会显示被保留的各个提示词版本累计的开销，直到压缩遮蔽它们。随后 `assistant/message` 用量上的 `cacheReadTokens` 是可观察的效果：对具备能力的路由，该值覆盖到最后一条已缓存消息为止的前缀；对不具备能力的路由，它回落到公共前缀检测的下限。
+
+### 验证计划
+
+- `dsh-agent-loop` 中针对投影的单元测试：序列中途变更时追加、没有存活的历史中途节点时在序列开始处替换、有存活节点时在序列开始处追加、恢复时追加、未变更时无操作，以及不具备能力的路由只做替换。
+- `dsh-llm-deepseek` 中针对目录校验（`systemPromptUpdate` 只接受 `'in-history'`）和 `prepareCall()` 暴露该字段的单元测试。
+- `snapshots/` 下的一个无密钥录制快照，其组合在 mock 路由上声明该能力并在会话中途切换 plan 模式，钉住追加的 `system/message` 与未被触及的第 0 号节点；TypeScript 与 Python SDK 的期望输出包含追加的事件。
+- 一个真实 API 的 e2e：针对具备能力的路由运行两个步骤并夹带一次提示词变更，断言第二个请求的 `cacheReadTokens` 不小于第一个请求的提示词 token 数。它通过标准的凭据与 base-URL 机制解析路由，未配置具备能力的路由时自动跳过。
+
+## Alternatives considered
+
+**只发送变化的片段作为增量。** 模型把最新的系统消息当作完整提示词，因此增量会静默丢掉每个未变化的片段。基于模型约定被否决。
+
+**用插件配置而不是模型能力启用历史内模式。** 部署标志可能把不具备能力的模型与追加的系统消息配对，这样的模型最多把它们当作普通历史。该能力属于兑现它的路由；适配器目录已经承载逐模型的容量信息。被否决。
+
+**永远追加，从不重新基线化。** 规则单一，但第 0 号节点会在会话整个生命周期内保持过时，压缩之后的每个请求都要携带过时的头部加替换消息。在序列开始处重新基线化不花额外代价，因为缓存在那里已经丢失。被否决。
+
+**每次恢复都重新基线化。** 为更简单的恢复路径接受每次进程重启一次缓存未命中。缓存跨重启持续数小时到数天，而日志已经承载恢复所需的一切。被否决。
+
+**把系统消息放在该步骤的用户消息之后。** 两个位置都在已缓存前缀之后，但模型会在读到必须应用指令的输入之后才读到指令；system 在 user 之前与最前位置的顺序一致。被否决。
+
+## Acceptance criteria
+
+- `DeepSeekCatalogModel.systemPromptUpdate` 在加载时校验、通过 `LlmResolvedModelInfo` 暴露、由 `prepareCall()` 返回；拼错的值在加载时失败。
+- 在具备能力的路由上，序列中途的提示词变更在该步骤的 `user/message` 事件之前追加 `system/message`，第 0 号节点不变；在不具备能力的路由上，同样的变更替换第 0 号节点。
+- 在具备能力的路由上，没有存活的历史中途系统节点的序列开始替换第 0 号节点；有存活节点时追加。
+- 渲染后的提示词不同的已恢复循环实例在具备能力的路由上追加。
+- 录制快照与两个 SDK 的期望输出钉住追加的事件；配置了具备能力的路由时 e2e 断言缓存命中不等式，否则跳过。
+- `dsh-llm-deepseek`、`dsh-agent-loop`、`dsh-system-prompt` 的 README 记录该能力、决策规则和 KV Cache 效果；`docs/config-catalog.md` 列出该字段。
+
+## Risks
+
+- 模型约定尚未公开；本 Agent Note 按所提供的内容记录。若发布的模型收窄了约定（例如只在有界窗口内兑现最新的系统消息），决策规则需要序列开始之外的重新基线化触发条件。
+- 被保留的提示词版本在历史中累积，直到压缩遮蔽它们。每个版本在该序列的每个请求上都要付出其 token 开销；提示词在多数步骤都变化的部署，更适合把那个事实移入运行时上下文。
+- 重写或重排系统消息的代理会静默破坏替换语义；e2e 的缓存命中断言是探测器。

Package-local `.perf.ts` files remain non-gating diagnostics; `scripts/` owns orchestration rather than benchmark cases.

+# Agent Note: Standard hosted runner for required benchmarks
+
+Status: implemented
+
+English | [中文](2026-09-06-standard-hosted-benchmark-runner.zh.md)
+
+## Problem
+
+Wall-clock performance checks need an isolated execution lane and a consistent runner class. Routing them through the enterprise Linux failover switch makes their measurements depend on either larger hosted capacity or a shared self-hosted VM, while also consuming capacity needed by parallel correctness checks.
+
+## Decision
+
+The required benchmark job in [ci.yml](../../../../.github/workflows/ci.yml) uses the standard GitHub-hosted `ubuntu-24.04` runner independently of Linux failover. It always attempts to restore the pnpm store cache and retains a standalone benchmark lane. The complete job has a 15-minute timeout covering setup, installation, builds, and measurements. This bounds infrastructure execution, not an individual performance assertion.
+
+The [Session performance decision](2026-09-04-session-open-performance-gate.md) continues to own workloads, timing and memory budgets, worker isolation, and calibration. Runner selection does not relax those budgets or the worker, test, and hook deadlines. Successful raw measurements remain in the Actions log through step-local `DSH_GATE_VERBOSE=1`. The hardware-comparison workflows retain their deliberately different runner sizes.
+
+## Alternatives considered
+
+- Enterprise or shared self-hosted routing retains more build capacity but ties the measurement environment to unrelated failover operations.
+- Increasing performance thresholds together with the job timeout conflates a bounded CI execution with a regression allowance. Threshold changes require measured calibration and positive and negative controls.
+
+## Consequences
+
+A standard runner trades parallel build capacity for a fixed measurement class without removing the required verdict. Cache misses and runner variation can still affect total duration. Each runner change needs an actual hosted benchmark run before its job timeout is treated as validated; local workflow assertions alone cannot establish execution time.
+
+The owning [workflow tests](../../../../scripts/ci-workflow.spec.ts) pin runner routing, unconditional cache restoration, required status, and the job timeout. Negative controls reject failover routing, a cache condition, and the former 30-minute job bound.

+# Agent Note: 必需 benchmark 使用标准托管运行器
+
+Status: implemented
+
+[English](2026-09-06-standard-hosted-benchmark-runner.md) | 中文
+
+## 问题
+
+壁钟性能检查需要独立执行的 lane 和一致的运行器类别。通过企业 Linux 故障转移开关路由这些检查，会让测量取决于大型托管运行器或共享自托管虚拟机，同时占用并行正确性检查所需的容量。
+
+## 决定
+
+[ci.yml](../../../../.github/workflows/ci.yml) 中的必需 benchmark job 使用标准 GitHub 托管 `ubuntu-24.04` 运行器，不受 Linux 故障转移影响。它始终尝试恢复 pnpm 存储缓存，并保留独立的 benchmark lane。整个 job 的超时为 15 分钟，覆盖准备、安装、构建和测量。这限制的是基础设施执行时间，而非单项性能断言。
+
+[Session 性能决策](2026-09-04-session-open-performance-gate.zh.md) 继续拥有工作负载、时间和内存预算、worker 隔离及校准。运行器选择不放宽这些预算，也不放宽 worker、测试和钩子的截止时间。步骤级 `DSH_GATE_VERBOSE=1` 使成功运行的原始测量保留在 Actions 日志中。硬件比较工作流保留有意设置的不同运行器规格。
+
+## 考虑过的替代方案
+
+- 企业或共享自托管路由保留更多构建容量，但使测量环境受无关故障转移操作影响。
+- 同时提高性能阈值和 job 超时，会混淆有界 CI 执行与退化容许量。阈值调整需要实测校准及正反例。
+
+## 后果
+
+标准运行器以并行构建容量换取固定测量类别，不移除必需判定。缓存未命中和运行器波动仍会影响总耗时。每次更换运行器都需要实际托管 benchmark 运行，才能认定 job 超时经过验证；本地工作流断言无法单独证明执行耗时。
+
+所属[工作流测试](../../../../scripts/ci-workflow.spec.ts) 固定运行器路由、无条件缓存恢复、必需状态及 job 超时。反例验证拒绝故障转移路由、缓存条件和原来的 30 分钟 job 上限。

See [scripts/run-gates.ts](../scripts/run-gates.ts) and the workflow files for the current gate and job inventory.
 
 The credential-free dsh dependency-layout and dsh/vendor pack rehearsals use the existing Linux self-hosted pool only when `DSH_CI_FAILOVER_LINUX=selfhosted` and the event is a trusted master push or same-repository, non-fork, non-Dependabot pull request. All other cases, including manual dispatch, use `ubuntu-24.04`; manual publication stays hosted. See the [release rehearsal runner decision](../.agents/notes/implemented/process/2026-09-06-release-rehearsal-selfhosted.md) for persistent-store isolation and fallback limits.

 The performance gate does not duplicate semantic assertions owned by functional tests; it requires only that the target call completes and reaches its measured endpoint.

 The pre-stack implementation keeps V0 as its current format, so first open does not change its on-disk representation; its native V0 first-history and Agent-resume measurements therefore apply to both lifecycle rows.
 
+The [standard two-CPU run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34023970384/job/101461539961) at `ca3ffe95dac2c55eefeb16ed9b61067bbd19ee90` uses Node 24.20.0 x64 and Ubuntu image `20260831.293.1`. Its five current-generation `open` samples are 49.2, 47.4, 49.1, 48.6, and 48.1 ms: median 48.6 ms, maximum 49.2 ms. The rounded 50 ms CI expectation gives a 63 ms limit without reapplying the 2× machine scale. The log identifies two available CPUs but not their model; it does not isolate hardware from the Node-version change. This is endpoint-specific runner calibration, not evidence of an application optimization or a new reference-machine measurement. Every other benchmark passes its existing budget. Deterministic controls reject the observed median at the historical 30 ms limit, accept it at 63 ms, reject a synthetic 75 ms reopen median, and reject a synthetic 4,000 ms first-open duration at its unchanged 550 ms limit. These controls verify budget enforcement, not a measured new regression.

 ## Alternatives considered
 
 - Enterprise or shared self-hosted routing retains more build capacity but ties the measurement environment to unrelated failover operations.
-- Increasing performance thresholds together with the job timeout conflates a bounded CI execution with a regression allowance. Threshold changes require measured calibration and positive and negative controls.

 ## Problem
 
-The three required Linux worker jobs in [CI](../../../../.github/workflows/ci.yml) (`node 24 / static`, `node 24 / coverage`, `node 24 / snapshots and artifacts`) run on the hosted enterprise 32-core pools; the required verdict job that aggregates them (`all checks passed`) runs on standard `ubuntu-latest`; the [native Windows jobs](2026-08-08-native-windows-pull-request-ci.md) run on the hosted `dsh-windows-2025-16core` larger runner. When the enterprise pools degrade — jobs queue indefinitely or the enterprise labels vanish — every open pull request becomes unmergeable, and the ordinary recovery of merging a fix is itself deadlocked behind the very required checks that cannot run. **Scope: two independent switches, one per platform.** `DSH_CI_FAILOVER_LINUX` recovers an enterprise Linux-pool outage (the three required Linux workers plus the `all checks passed` verdict); `DSH_CI_FAILOVER_WINDOWS` recovers a hosted Windows-pool outage (the native Windows jobs and eligible Windows x64 Python runtime CI builds; see [the Python runtime note](../../proposed/process/2026-09-06-python-runtime-windows-selfhosted.md)). A Linux-pool outage need not retarget Windows jobs and vice versa. The verdict's other required dependencies (`node-compat`, `python-sdk`, `windows`) stay on standard hosted runners by design (the portable boundary); in a broader GitHub-hosted capacity failure that also takes out the standard pools, those dependencies still block `all checks passed`. An outage therefore needs a switch any responder with repository write access can throw without merging anything.

Subject: [PATCH 67/70] revert(ci): run Windows Python runtime CI on
 GitHub-hosted Windows

Windows x64 runtime builds resolve their hosted matrix.runner unconditionally
again (windows-2025 for pull-request CI). Remove the DSH_CI_FAILOVER_WINDOWS
selector, job-private Python toolchain, self-hosted dependency install and
post-step cleanup, the private setup script, and the routing spec introduced
in #3629. The Windows failover switch again covers only the native Windows
jobs in ci.yml.

Subject: [PATCH 68/70] docs(notes): record hosted Windows runtime decision,
 reject proposal

The failover runbook's Windows switch scope returns to the native Windows jobs:
remove the Python runtime eligibility sentences, the pool Python prerequisite,
and the links to the proposal. The self-hosted Python runtime proposal is
moved to rejected with its unmeasured-throughput verdict, and a new
implemented note records that the Windows x64 runtime lane stays on
GitHub-hosted Windows with the reasons. Bilingual sidecars re-recorded.

 ## Problem
 
-The three required Linux worker jobs in [CI](../../../../.github/workflows/ci.yml) (`node 24 / static`, `node 24 / coverage`, `node 24 / snapshots and artifacts`) run on the hosted enterprise 32-core pools; the required verdict job that aggregates them (`all checks passed`) runs on standard `ubuntu-latest`; the [native Windows jobs](2026-08-08-native-windows-pull-request-ci.md) run on the hosted `dsh-windows-2025-16core` larger runner. When the enterprise pools degrade — jobs queue indefinitely or the enterprise labels vanish — every open pull request becomes unmergeable, and the ordinary recovery of merging a fix is itself deadlocked behind the very required checks that cannot run. **Scope: two independent switches, one per platform.** `DSH_CI_FAILOVER_LINUX` recovers an enterprise Linux-pool outage (the three required Linux workers plus the `all checks passed` verdict); `DSH_CI_FAILOVER_WINDOWS` recovers a hosted Windows-pool outage (the native Windows jobs and eligible Windows x64 Python runtime CI builds; see [the Python runtime note](../../proposed/process/2026-09-06-python-runtime-windows-selfhosted.md)). A Linux-pool outage need not retarget Windows jobs and vice versa. The verdict's other required dependencies (`node-compat`, `python-sdk`, `windows`) stay on standard hosted runners by design (the portable boundary); in a broader GitHub-hosted capacity failure that also takes out the standard pools, those dependencies still block `all checks passed`. An outage therefore needs a switch any responder with repository write access can throw without merging anything.

 ## Decision
 
-Each of the three required Linux worker jobs, the native Windows jobs, and the `all checks passed` verdict job — which would otherwise stay queued on the failed pool even after every worker passed — resolves its runner pool through a repository variable, and the switch is split by platform so an outage on one platform does not retarget the other. The three Linux workers and the `all checks passed` verdict (whose `needs` are the required Linux workers and which runs on the `vm-backup` pool) resolve through `DSH_CI_FAILOVER_LINUX`; the native Windows jobs and eligible Windows x64 Python runtime CI builds resolve through `DSH_CI_FAILOVER_WINDOWS`. Unset, they default to their hosted pools; selecting `selfhosted` is an explicit operator choice. Set to `selfhosted` by any repository writer, the corresponding jobs retarget onto the in-house self-hosted pool: under `DSH_CI_FAILOVER_LINUX`, the Linux jobs and verdict move onto the `vm-backup` pool, snapshot concurrency drops to the shared-VM bound, and the hosted-path pnpm cache restores are skipped; under `DSH_CI_FAILOVER_WINDOWS`, the native Windows jobs and eligible Windows x64 Python runtime CI builds move onto the `dsh-win-ci` pool. Each switch is writer-manageable repository state, not a merge, so it works while every check is red. The in-house pools' readiness is continuously re-proven by the `serial / linux (self-hosted standby)` and `serial / windows (self-hosted standby)` lanes, which run the complete unsharded aggregates on every master push.

 `ci-master.yml` exempts exactly one event from `cancel-in-progress` (`${{ github.event_name != 'push' }}`), so one master push does not cancel the drill still running from the previous one. Each drill runs its complete unsharded aggregate with one gate worker, which takes longer than the interval between master merges; under unconditional cancellation a drill is superseded before reaching a verdict and the lane yields no readiness evidence for a responder to check.

Jobs already **queued** for the hosted labels do not retarget and cannot be re-run in place, so for the documented indefinite-queue outage, cancel the stuck run and re-run all jobs, or push a new commit; "Re-run failed jobs" only helps once a job has actually failed rather than queued.

+## Problem
+
+The Windows x64 target in [build-exe-for-python-sdk.yml](../../../../.github/workflows/build-exe-for-python-sdk.yml) started resolving through `DSH_CI_FAILOVER_WINDOWS=selfhosted` for trusted pull-request CI when #3629 added the failover selector and the job-private Windows toolchain. The shared `dsh-win-ci` pool did not make the lane more reliable. On 2026-09-06 the installed-wheel smoke passed at 09:12 on `dsh-win-ci-16` for [an earlier commit of the same pull request](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34023970384), then failed at 10:06 on `dsh-win-ci-21` for [another pull request](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34026500701) and at 10:46 on `dsh-win-ci-04` for [the same pull request](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34028339888/job/101473395734), where `smoke_sdk_profile_plugin`'s packaged `dsh plugin add` child exited without output while the Linux and macOS cells of that run passed. The [migration proposal](../../rejected/process/2026-09-06-python-runtime-windows-selfhosted.md) remained `proposed` because its throughput and shared-load acceptance criteria were never measured.
+
+## Decision
+
+The Windows x64 target always uses its hosted `matrix.runner` — `windows-2025` for pull-request CI — with the standard setup-python toolchain, the pnpm cache restore, and the pkg cache. The failover selector, the job-private Python setup step, the self-hosted dependency install and post-step cleanup, the private setup script, and the routing spec from #3629 are removed. `DSH_CI_FAILOVER_WINDOWS=selfhosted` again retargets only the native Windows jobs in [ci.yml](../../../../.github/workflows/ci.yml); the [failover runbook](2026-07-26-ci-failover-runbook.md) and [python/development.md](../../../../python/development.md) describe hosted-only runtime builds. The migration's UTF-8 mode exports existed because the persistent host used a GBK default code page; hosted images provide the locale the lane previously ran under.
+
+## Alternatives considered
+
+**Keep the failover routing.** Rejected: the shared pool reproduced the same silent installed-wheel child death twice in one day while the migrated inventory's throughput acceptance stayed open, and routing a correctness lane through failover state couples it to an unrelated pool-outage switch.
+
+**Fix the shared pool instead.** Left to pool operators: the observed failures are subprocesses dying without output, not a missing image prerequisite, and the same image serves the native Windows failover jobs.
+
+**Retain the job-private toolchain on hosted images.** Rejected: the private uv/Python download exists to avoid mutating a persistent shared host; disposable hosted images already provide the registered Python 3.10 toolchain the pre-migration lane used.
+
+## Consequences
+
+Every qualifying pull request again pays GitHub-hosted Windows capacity for the runtime build, and the job-private setup and cleanup machinery — including the bounded filesystem retries — is gone with the lane. In exchange each build runs on a disposable host with the proven toolchain and hosted caches, and the Windows failover switch covers only the native Windows jobs as documented before the migration. A future self-hosted attempt must re-validate throughput and failure reproducibility on the actual pool before any routing change.

+## 问题
+
+当 #3629 加入故障切换选择器与作业私有的 Windows 工具链后，[build-exe-for-python-sdk.yml](../../../../.github/workflows/build-exe-for-python-sdk.yml) 中的 Windows x64 目标开始对受信任的 PR CI 通过 `DSH_CI_FAILOVER_WINDOWS=selfhosted` 解析运行器。共享的 `dsh-win-ci` 池并未让该通道更可靠。2026-09-06，安装后 wheel 冒烟测试在 09:12 于 `dsh-win-ci-16` 上为[同一拉取请求的较早提交](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34023970384)通过，随后 10:06 在 `dsh-win-ci-21` 上为[另一个拉取请求](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34026500701)失败，10:46 在 `dsh-win-ci-04` 上为[同一拉取请求](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34028339888/job/101473395734)失败——`smoke_sdk_profile_plugin` 打包的 `dsh plugin add` 子进程无输出即退出，而该次运行的 Linux 与 macOS 单元均通过。[迁移提案](../../rejected/process/2026-09-06-python-runtime-windows-selfhosted.zh.md) 保持 `proposed`，因为其吞吐量与共享负载验收标准从未实测。
+
+## 决策
+
+Windows x64 目标始终使用托管的 `matrix.runner`——PR CI 为 `windows-2025`——配以标准 setup-python 工具链、pnpm 缓存恢复与 pkg 缓存。来自 #3629 的故障切换选择器、作业私有 Python 准备步骤、自托管依赖安装与后置清理、私有准备脚本及路由测试均被移除。`DSH_CI_FAILOVER_WINDOWS=selfhosted` 再次只重定向 [ci.yml](../../../../.github/workflows/ci.yml) 中的原生 Windows 作业；[故障切换手册](2026-07-26-ci-failover-runbook.zh.md)与 [python/development.zh.md](../../../../python/development.zh.md) 描述仅托管的 runtime 构建。迁移中的 UTF-8 模式导出之所以存在，是因为持久主机使用 GBK 默认代码页；托管镜像提供该通道此前运行的区域设置。
+
+## 已考虑的替代方案
+
+**保留故障切换路由。** 不采用：共享池同一天两次复现相同的安装后 wheel 子进程无声死亡，而迁移清单的吞吐量验收仍然悬置；并且把正确性通道路由进故障切换状态，会使其耦合到无关的池故障开关。
+
+**改为修复共享池。** 交由池运维者处理：观测到的失败是无输出即退出的子进程，而非镜像前置条件缺失；同一镜像还服务原生 Windows 故障切换作业。
+
+**在托管镜像上保留作业私有工具链。** 不采用：私有 uv/Python 下载的存在理由是不修改持久共享主机；一次性托管镜像已提供迁移前通道使用的已注册 Python 3.10 工具链。
+
+## 后果
+
+每个符合条件的拉取请求再次为 runtime 构建支付 GitHub 托管 Windows 容量，作业私有准备与清理机制（包括有界文件系统重试）随通道一同移除。交换来的是每次构建运行在带标准工具链与托管缓存的一次性主机上，且 Windows 故障切换开关只覆盖迁移前文档所述的原生 Windows 作业。未来的自托管尝试必须在任何路由变更前，对实际池重新验证吞吐量与失败可复现性。

Subject: [PATCH 69/70] docs(notes): record hosted Windows runtime decision,
 retire the proposal

The failover runbook's Windows switch scope returns to the native Windows jobs:
remove the Python runtime eligibility sentences, the pool Python prerequisite,
and the proposal links. The #3629 self-hosted Python runtime proposal is
retired (deleted as obsolete after its unmeasured-throughput run), and a new
implemented note records that the Windows x64 runtime lane stays on
GitHub-hosted Windows with the evidence and alternatives. Bilingual sidecars
re-recorded.

-# Agent Note: Job-private Windows Python runtime CI
-
-Status: rejected — no measured throughput win; the shared pool reproduced the installed-wheel failure and the lane returned to hosted Windows
-
-English | [中文](2026-09-06-python-runtime-windows-selfhosted.zh.md)
-
-## Problem
-
-The native Python runtime matrix consumes hosted Windows capacity, but moving its build unchanged onto shared persistent runners would modify machine installation state and reuse user-level caches. The [CI failover runbook](../../implemented/process/2026-07-26-ci-failover-runbook.md) remains the owner of the existing general-purpose lanes and pool prerequisites; the [native Windows CI note](../../implemented/process/2026-08-08-native-windows-pull-request-ci.md) owns the independent Wine/native topology. This proposal covers only Python runtime builds.
-
-The [read-only prerequisite probe](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012679056) found native Windows x64, Python 3.14.7 with venv/ensurepip, and enabled Developer Mode, but no Python toolcache. Linux lacked Docker, which both manylinux steps require. These observations permit a Windows-only experiment, not a claim that the runtime build passes.
-
-## Proposal
-
-Route only the Windows x64 target in [the runtime workflow](../../../../.github/workflows/build-exe-for-python-sdk.yml) to the persistent pool when `inputs.ci && !inputs.release`, the repository is the canonical repository, and the event is a same-repository non-fork, non-Dependabot PR. `DSH_CI_FAILOVER_WINDOWS=selfhosted` enables this routing; an unset or different value keeps the lane hosted. Release/manual builds, other events, Linux/macOS targets, planning, and the SDK-wheel job remain hosted. Throughput comparison and concurrent-job/cancellation acceptance remain pending.
-
-The [native setup probe](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34013261224/job/101432611073) downloads Python 3.10.20, verifies command resolution and a seeded smoke venv, asserts unchanged registered Python installations and Developer Mode, and proves job-root deletion. Windows recursive removal needs bounded retries after an observed non-empty-directory failure. The workflow additionally clears the exported compile-cache path and resets temporary-directory variables before action post-steps; focused tests pin those assignments, which are not part of the cited probe commit. The focused routing tests pass, and an inverted failover condition produces three expected failures before restoration. The first full native run builds the executable and wheel but fails when Python reads UTF-8 Session JSONL with the host GBK default. The setup exports Python UTF-8 mode and UTF-8 standard streams; a local forced-ASCII-locale subprocess reproduces the default-decoding failure and verifies the setting. The [corrected native Windows job](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34014942421/job/101437029350) completed successfully in 523 seconds, including executable and release-shaped wheel builds, installed-wheel keyless/live-API tests, upload, private-root cleanup, and action post-steps.
-
-The [private setup script](../../../../scripts/setup-python-runtime-windows.ps1) bootstraps uv 0.11.23 inside a temporary venv using the preinstalled interpreter, then downloads managed Python 3.10 into a unique job directory with `--no-bin --no-registry`. It creates a seeded tooling venv without further Python downloads. These flags exist in the [pinned uv source](https://github.com/astral-sh/uv/blob/3cdf50e0924f1ace7a92ddbac98b12a958b87688/crates/uv-cli/src/lib.rs#L6672-L6713); the [implementation](https://github.com/astral-sh/uv/blob/3cdf50e0924f1ace7a92ddbac98b12a958b87688/crates/uv/src/commands/python/install.rs#L667-L723) suppresses executable links and registry registration. CI checks Developer Mode rather than enabling it.
-
-The job owns its pnpm store, pkg/npm/node-gyp/Python/Node caches and temporary test directories. Dependency imports use copy rather than links into a shared store; hosted cache restore/save steps are skipped. An always-run cleanup removes only the recorded job root. Checkout does not persist credentials. These are resource-isolation measures, not protection against malicious code running under the same Windows account.
-
-## Alternatives considered
-
-**An independent Python failover switch.** Rejected for this shared host: reusing `DSH_CI_FAILOVER_WINDOWS` lets responders recover the platform with one switch and adds no variable. The trade-off is coupled placement: enabling native Windows failover also adds eligible Python runtime builds and their cold private-tool/cache setup load to the same host; clearing it returns both workloads to hosted pools.
-
-**Cold setup-python with a private toolcache.** Rejected: the concrete Python 3.10.11 [Windows release installer](https://github.com/actions/python-versions/blob/98e79473eb342d6f43487a289ca633620404742e/installers/win-setup-template.ps1#L21-L70) removes matching machine/current-user installation records and installs for all users. A private directory does not isolate that registry state.
-
-**Administrator-preprovisioned Python 3.10.** Viable with enforced cache-hit-only use and private dependency environments, but the measured pool does not supply it. Portable uv avoids requiring a host installation change.
-
-**Migrate Linux simultaneously.** Deferred until administrator-approved Docker provisioning and manylinux validation; skipping either manylinux step would weaken the wheel compatibility check.
-
-## Acceptance criteria
-
-- Selector tests prove hosted routing for release/manual, foreign/fork/Dependabot events, non-Windows targets, and an unset or unknown switch value.
-- A trusted native Windows run builds the executable and release-shaped wheel, passes installed-wheel keyless and required live-API tests, and uploads the wheel without global Python or registry writes.
-- Concurrent jobs use distinct cache/tool roots; success, failure, and cancellation exercise cleanup without deleting another job’s paths.
-- Compare elapsed time and shared-pool load against hosted Windows before claiming cost or throughput improvement. Until then this note remains proposed.
-
-## Risks
-
-Private stores and copy imports trade warm-cache speed and disk space for bounded mutation. Portable Python can select a different 3.10 patch from setup-python. Downloads remain external dependencies; hard runner termination can prevent cleanup. Shared-account trust and pool availability remain operational limits, and the hosted fallback does not prove self-hosted readiness.

-## 问题
-
-原生 Python runtime 矩阵消耗托管 Windows 容量，但将构建原样迁移到共享常驻运行器会修改机器安装状态并复用用户级缓存。[CI 故障切换手册](../../implemented/process/2026-07-26-ci-failover-runbook.zh.md) 继续负责现有通用通道与运行器池前置条件；[原生 Windows CI 说明](../../implemented/process/2026-08-08-native-windows-pull-request-ci.zh.md) 负责独立的 Wine/原生拓扑。本提案仅覆盖 Python runtime 构建。
-
-[只读前置条件探测](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012679056) 发现 Windows 为原生 x64，Python 3.14.7 提供 venv/ensurepip，开发人员模式已启用，但没有 Python 工具缓存。Linux 缺少两个 manylinux 步骤都依赖的 Docker。这些观测允许开展仅针对 Windows 的实验，并不证明 runtime 构建能够通过。
-
-## 提案
-
-仅当 `inputs.ci && !inputs.release`、仓库为规范仓库，且事件为同仓库非 fork、非 Dependabot 的 PR（Pull Request）时，将 [runtime 工作流](../../../../.github/workflows/build-exe-for-python-sdk.yml) 的 Windows x64 目标路由到常驻运行器池。`DSH_CI_FAILOVER_WINDOWS=selfhosted` 启用此路由；未设置或其他值使通道留在托管运行器。发布/手动构建、其他事件、Linux/macOS 目标、规划作业与 SDK wheel 包作业继续使用托管运行器。吞吐量对比及并发作业/取消验收仍待完成。
-
-[原生准备探测](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34013261224/job/101432611073) 下载 Python 3.10.20，验证命令解析与包含 pip 的冒烟 venv，断言已注册的 Python 安装与开发人员模式不变，并证明作业根目录已删除。观测到目录非空的删除失败后，Windows 递归删除使用有限重试。工作流另外在 action 后置步骤前清除导出的编译缓存路径并重置临时目录变量；定向测试固定这些赋值，它们不属于引用的探测提交。定向路由测试通过，反转故障切换条件会产生三个预期失败，随后恢复条件。首次完整原生运行成功构建可执行文件与 wheel 包，但 Python 用主机默认 GBK 编码读取 UTF-8 Session JSONL 时失败。准备脚本导出 Python UTF-8 模式与 UTF-8 标准流；本地强制 ASCII locale 的子进程复现默认解码失败并验证设置。[修复后的原生 Windows 作业](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34014942421/job/101437029350) 在 523 秒内成功完成，包括可执行文件与发布形态 wheel 包构建、安装后 wheel 包的无密钥/真实 API 测试、上传、私有根目录清理及 action 后置步骤。
-
-[私有准备脚本](../../../../scripts/setup-python-runtime-windows.ps1) 使用预装解释器，在临时 venv 内引导安装 uv 0.11.23，再通过 `--no-bin --no-registry` 将托管 Python 3.10 下载到唯一的作业目录。它创建包含初始工具包的工具 venv，禁止进一步下载 Python。[固定版本的 uv 源码](https://github.com/astral-sh/uv/blob/3cdf50e0924f1ace7a92ddbac98b12a958b87688/crates/uv-cli/src/lib.rs#L6672-L6713) 提供这些参数；[实现](https://github.com/astral-sh/uv/blob/3cdf50e0924f1ace7a92ddbac98b12a958b87688/crates/uv/src/commands/python/install.rs#L667-L723) 禁止创建可执行文件链接与注册表登记。CI 检查开发人员模式，不负责启用它。
-
-作业独占其 pnpm 存储、pkg/npm/node-gyp/Python/Node 缓存以及临时测试目录。依赖导入使用复制，而不是指向共享存储的链接；跳过托管缓存恢复/保存步骤。始终执行的清理步骤仅删除记录的作业根目录。检出不保留凭据。这些措施隔离资源，不能防御同一 Windows 账户下运行的恶意代码。
-
-## 已考虑的替代方案
-
-**独立的 Python 故障切换开关。** 对这台共享主机不采用：复用 `DSH_CI_FAILOVER_WINDOWS` 让响应者用一个开关恢复整个平台，不新增变量。代价是部署位置相互绑定：启用原生 Windows 故障切换也会把符合条件的 Python runtime 构建及其私有工具/缓存冷启动负载加到同一主机上；清除开关则让两类工作负载都回到托管池。
-
-**使用私有工具缓存冷启动 setup-python。** 不采用：具体的 Python 3.10.11 [Windows 发布安装器](https://github.com/actions/python-versions/blob/98e79473eb342d6f43487a289ca633620404742e/installers/win-setup-template.ps1#L21-L70) 会删除匹配的机器/当前用户安装记录，并为所有用户安装。私有目录无法隔离这些注册表状态。
-
-**由管理员预装 Python 3.10。** 强制仅使用缓存命中路径并采用私有依赖环境时可行，但观测到的运行器池并未提供它。便携 uv 避免要求修改主机安装。
-
-**同时迁移 Linux。** 推迟到管理员批准 Docker 部署并完成 manylinux 验证之后；跳过任一 manylinux 步骤都会削弱 wheel 包兼容性检查。
-
-## 验收标准
-
-- 选择器测试证明发布/手动、外部仓库/fork/Dependabot 事件、非 Windows 目标及未设置或未知的开关值均使用托管路由。
-- 一次可信的原生 Windows 运行构建可执行文件与发布形态 wheel 包，通过安装后 wheel 包的无密钥测试及必需的真实 API 测试，并上传 wheel 包，期间不写全局 Python 或注册表。
-- 并发作业使用不同的缓存/工具根目录；成功、失败与取消路径均执行清理且不删除其他作业的路径。
-- 在宣称成本或吞吐量改善之前，对比托管 Windows 的耗时与共享池负载。此前本说明保持 proposed 状态。
-
-## 风险
-
-私有存储与复制导入以热缓存速度和磁盘空间换取受限的修改范围。便携 Python 可能选择与 setup-python 不同的 3.10 补丁版本。下载仍依赖外部服务；运行器被强制终止可能阻止清理。共享账户信任与运行器池可用性仍是运维限制，托管回退也不能证明自托管运行器已就绪。

+# Agent Note: Wait for the Windows Python console runtime
+
+Status: implemented
+
+English | [中文](2026-09-06-windows-python-console-spawn-wait.zh.md)
+
+## Problem
+
+The installed Python `dsh.exe` console command intermittently exits with Windows access violation `0xc0000005` before initializing a profile. Its smoke assertion omitted the process status and reported only empty streams. A [native faulthandler probe](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34030851888) captures the fault in Python 3.10 `os._execvpe`, called by the runtime console entry, rather than in the bundled Node executable. Direct executable controls pass.
+
+## Decision
+
+The [Python console entry](../../../../python/sdk-runtime/src/deepseek_harness_runtime/__init__.py) uses `subprocess.run` on Windows, inherits standard streams and environment, waits for runtime completion, and exits with the runtime status. POSIX retains `os.execvpe` process replacement. Windows CRT exec is not POSIX process replacement; the explicit spawn-and-wait path avoids the observed native exec operation.
+
+The [installed-wheel smoke](../../../../scripts/smoke-python-runtime.py) reports decimal and unsigned 32-bit hexadecimal status alongside captured streams when profile installation fails. This preserves the distinction between ordinary command failure and native process exceptions.
+
+## Alternatives considered
+
+**Disable Node compile caching.** Not selected: cache environment changes correlated with early probes, but cold-cache controls also passed and Python faulthandler locates the actual fault at the native exec call. Cache configuration remains unchanged.
+
+**Retry or bypass the installed console command.** Rejected because either masks the shipped command failure instead of repairing its process launch. The keyless installed-wheel assertion remains required.
+
+## Consequences
+
+Windows keeps a Python parent until the runtime exits; it no longer depends on CRT overlay behavior. The standard synchronous subprocess implementation owns waiting and interruption cleanup. No custom process-tree manager or global host setting is added.
+
+[Runtime-resolution tests](../../../../python/sdk/tests/test_runtime_resolution.py) retain POSIX forwarding and cover Windows argument/environment forwarding, statuses 0/37/513, real child completion, Unicode streams and arguments with spaces. Native Windows owns the wide exit-status case because POSIX truncates process statuses to eight bits. The [native fixed-count comparison](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34031142773) passes all four patched launches with compile caching enabled; all four unpatched controls also pass in that batch, so it is not a same-batch reproduction. Full installed-wheel CI must validate the final artifact separately from local branch-level tests.

+# Agent Note: 等待 Windows Python 控制台运行时
+
+Status: implemented
+
+[English](2026-09-06-windows-python-console-spawn-wait.md) | 中文
+
+## 问题
+
+Python 安装的 `dsh.exe` 控制台命令会在初始化 profile 前间歇性地以 Windows 访问冲突 `0xc0000005` 退出。其冒烟断言遗漏进程状态，只报告空标准流。[原生 faulthandler 探测](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34030851888) 将故障定位在运行时控制台入口调用的 Python 3.10 `os._execvpe`，而非打包的 Node 可执行文件。直接启动可执行文件的对照通过。
+
+## 决策
+
+[Python 控制台入口](../../../../python/sdk-runtime/src/deepseek_harness_runtime/__init__.py) 在 Windows 上使用 `subprocess.run`，继承标准流与环境，等待运行时结束，再以运行时状态退出。POSIX 保留 `os.execvpe` 进程替换。Windows CRT exec 并非 POSIX 进程替换；显式启动并等待的路径避开观测到的原生 exec 操作。
+
+[安装后 wheel 冒烟测试](../../../../scripts/smoke-python-runtime.py) 在 profile 安装失败时，同时报告十进制、无符号 32 位十六进制状态与捕获的标准流。这保留普通命令失败和原生进程异常的区别。
+
+## 已考虑的替代方案
+
+**禁用 Node 编译缓存。** 未采用：早期探测中缓存环境变化与结果相关，但冷缓存对照也能通过，且 Python faulthandler 将实际故障定位在原生 exec 调用。缓存配置保持不变。
+
+**重试或绕过已安装的控制台命令。** 拒绝，因为二者都会掩盖已发布命令的失败，而不是修复进程启动。keyless 安装后 wheel 断言仍为必需检查。
+
+## 后果
+
+Windows 保留 Python 父进程直到运行时退出，不再依赖 CRT overlay 行为。标准同步子进程实现负责等待和中断清理。不添加自定义进程树管理器或全局主机设置。
+
+[运行时解析测试](../../../../python/sdk/tests/test_runtime_resolution.py) 保留 POSIX 转发验证，并覆盖 Windows 参数／环境转发、状态 0/37/513、真实子进程完成、Unicode 标准流和带空格的参数。宽退出状态由原生 Windows 验证，因为 POSIX 会将进程状态截断为八位。[原生固定次数对照](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34031142773) 中，启用编译缓存的四次修复后启动全部通过；该批次四次未修复对照也全部通过，因此它不是同批次复现。完整安装后 wheel CI 必须独立于本地分支级测试，验证最终产物。
