Agent and Session identity instead describe the subject of an asynchronous operation. A dynamic `ctx.agent` meaning “whichever Agent is running” would conflate those meanings and fail when one process drives Agents concurrently.

 Deep process-local infrastructure sometimes needs a trusted initiating Agent below explicit loop, tool, and request parameters—for example, a host-aware transport, tracing helper, logger, or gateway client. Requiring every private helper to forward `agent` adds repetition, while a process-global mutable slot is incorrect across `await`. Model-visible arguments are unsuitable because a model must not choose a trusted Session or routing header. The carrier belongs to the Agent service rather than optional model-visible context.

 `AgentRegistry` owns an ordered initiator lifecycle. Teardown first rejects new boundaries; removing `ctx.agents` then drains injected dependents such as AgentLoop, and the registry waits for active returned-Promise boundaries before calling `AsyncLocalStorage.disable()`. If a boundary's inherited async chain starts an owning Cordis fiber's unload, the private run-token lineage releases that nested boundary chain from the drain, which prevents teardown from waiting on itself while unrelated boundaries still drain. `currentInitiator()` and `requireInitiator()` remain usable through a retained in-flight service reference while the ordinary drain runs; after disposal, initiator methods throw `agent initiator scope is disposed`.

+## Problem
+
+An Agent's Cordis Context owns registrations and their cleanup. Agent identity instead selects the Session, runtime owner, event subject, authority decision, or wire identity for one operation. A reverse Agent property on Context made those two facts appear interchangeable: a caller could choose a Context for effect ownership and accidentally let that choice determine domain identity.
+
+The reverse association also required compensating mechanisms after type erasure. Host Remote forwarding inspected a routed subject for its Context, creation inferred runtime parentage from the caller Context, and adapters maintained reverse identity scans. These mechanisms duplicated identity already present in typed requests and obscured which caller owned an Agent at runtime.
+
+Without an explicit owner, `SubagentContinuationManager` creates and resumes children through its private plugin Context, so Context-based inference classifies every continuable child as a runtime root even though the manager holds its exact parent. Root-only consumers could then attach scheduling tools, grant direct-human goal authority, or route user questions as if the child were top-level.
+
+## Decision
+
+Runtime interfaces carry Agent identity at the point that owns it. `AgentSetup` receives `(agentCtx, agent)`; Agent creation and resume options carry `parentAgent` for a runtime child; scoped events carry their Agent in the payload; Remote forwarding verifies that `request.agent` is the carrier key; and Host Typert Context resolution maps wire identity to a live Agent Context without a reverse scan. `agent.ctx` remains the registration and lifecycle owner and exposes no reverse Agent property.
+
+Scope-aware registries continue to use the opaque scope key only for registration membership. Tool-subagent does not classify that key or resolve an Agent from Context. A direct `AgentSetup` passes the unpublished Session explicitly and installs through the supplied Context before publication. For a settings-backed standing preset, the event payload supplies the Agent, its Session supplies the policy target, and its Context owns the registrations.
+
+`SubagentContinuationManager` puts the exact parent in both fresh-creation and cold-resume options. A live continuable child is therefore excluded from `AgentRegistry.roots()` and satisfies `isOwnedBy(child.id, parent)`. Durable `parentSession` metadata does not substitute for this relation: a fork or resumed Session may be a runtime root when no live Agent owns it.
+
+The [Agent registration-scope decision](2026-07-08-agent-scope-contexts.md), its [runtime design](2026-07-12-agent-scope-runtime-design.md), and the [initiator-scope decision](2026-07-15-agent-initiator-scope.md) retain their independent registration, lifecycle, and private-chain rationale. This decision supersedes only the reverse Context association and implicit runtime-owner derivation described there.
+
+## Verification
+
+Agent creation tests pin explicit root and child ownership. Continuation integration tests keep a real child live long enough to assert both `roots()` exclusion and `isOwnedBy()` membership. Existing Schedule tests verify that root-only registrations stay absent from an explicitly owned child.
+
+Remote-event tests reject a missing or mismatched Agent before forwarding a scoped waterfall. Tool-subagent tests verify that direct setup installs before Session publication; standing-preset tests verify per-Session policy sampling and inheritance.
+
+## Alternatives considered
+
+**Keep `Context.agent`.** A reverse accessor makes registration ownership look like operation identity and requires every Context derivation, adapter, and test double to preserve an association unrelated to Cordis service selection or effect cleanup.
+
+**Infer runtime ownership from the caller Context.** A private manager Context, an Agent Context, and a standing preset Context can all call the same factory. Context ancestry therefore does not state which live Agent owns the result; the creator must put the parent it already knows in the request options.
+
+**Classify Agent scope keys.** An opaque scope key states routing membership, not domain identity. Classifying it would make Agent the center of composition and would still couple a plugin's effect owner to the Session whose policy it needs.
+
+**Use the initiating Agent as creation ownership.** Initiator scope records causal asynchronous execution, not lifetime ownership. A parent may initiate work that intentionally creates a root, and setup remains outside the child's driver boundary.
+
+**Use durable Session lineage.** `parentSession` records conversation ancestry across process lifetimes. Runtime ownership controls live roots and teardown, so equating the two would prevent a legitimately resumed fork from becoming a top-level Agent.
+
+## Consequences
+
+Lifecycle options, events, service requests, and transport requests carry explicit Agent identities, so each operation states the identity it uses and TypeScript checks both sides. Context remains reusable for dependency access and effect ownership without becoming an alternate domain-object locator.
+
+Continuable children have the same runtime parent relation as one-shot in-process children. Root-only consumers exclude them, parent teardown can reason from one live ownership graph, and durable lineage remains free to describe history rather than process-local lifetime.

+# Agent Note: 运行时边界显式携带 Agent 身份
+
+Status: implemented
+
+[English](2026-08-31-explicit-agent-runtime-identity.md) | 中文
+
+## 问题
+
+Agent 的 Cordis Context 拥有注册及其清理。Agent 身份则为某项操作选择会话、运行时所属方、事件主体、权限决策或协议身份。Context 上反向的 Agent 属性让这两个事实看起来可以互换：调用方选择用于管理 effect 所有权的 Context 时，可能意外地让该选择决定领域身份。
+
+类型信息被擦除后，这项反向关联还需要补偿机制。Host Remote 转发会从已路由主体检查其 Context，创建流程会从调用方 Context 推断运行时父级，适配器则维护反向身份扫描。这些机制重复类型化请求中已有的身份，也掩盖了哪个调用方在运行时拥有 Agent。
+
+若没有显式所属方，`SubagentContinuationManager` 会通过私有插件 Context 创建和恢复子级，因此基于 Context 的推断会把每个可续跑子级归类为 runtime root，尽管管理器持有其确切父级。仅限根级的消费方随后可能附加调度工具、授予直接人类输入对应的 Goal 权限，或像处理顶层 Agent 一样路由用户问题。
+
+## 决策
+
+运行时接口在拥有身份的位置携带 Agent 身份。`AgentSetup` 接收 `(agentCtx, agent)`；创建与恢复 Agent 的 options 通过 `parentAgent` 标识运行时子级；作用域事件在 payload 中携带 Agent；Remote 转发校验 `request.agent` 就是 carrier key；Host Typert Context 解析则把协议身份映射到存活 Agent Context，不执行反向扫描。`agent.ctx` 继续拥有注册和生命周期，不暴露反向 Agent 属性。
+
+感知作用域的注册表继续仅使用不透明作用域键判断注册成员关系。tool-subagent 不会分类该键，也不会从 Context 解析 Agent。直接 `AgentSetup` 显式传入尚未发布的 Session，并在发布前通过所给 Context 完成安装。对于由设置控制的常驻 preset，事件 payload 提供 Agent，其 Session 提供策略目标，其 Context 拥有注册项。
+
+`SubagentContinuationManager` 会把确切父级放进全新创建与冷恢复的 options。因此，存活的可续跑子级不会出现在 `AgentRegistry.roots()` 中，并且满足 `isOwnedBy(child.id, parent)`。持久化 `parentSession` 元数据不能代替这项关系：没有存活 Agent 拥有 fork 或已恢复会话时，它仍可成为 runtime root。
+
+[Agent 注册作用域决策](2026-07-08-agent-scope-contexts.zh.md)、其[运行时设计](2026-07-12-agent-scope-runtime-design.zh.md)和[发起方作用域决策](2026-07-15-agent-initiator-scope.zh.md)继续拥有各自独立的注册、生命周期及私有调用链理由。本决策只取代其中描述的反向 Context 关联和隐式运行时所属方推导。
+
+## 验证
+
+Agent 创建测试锁定显式的根级与子级归属。continuation 集成测试让一个真实子级保持存活，直到断言其既不属于 `roots()`、又满足 `isOwnedBy()`。现有 Schedule 测试验证仅限根级的注册项不会出现在显式归属的子级中。
+
+Remote 事件测试会在转发作用域 waterfall 前拒绝缺失或不匹配的 Agent。tool-subagent 测试验证 direct setup 会在 Session 发布前完成安装；常驻 preset 测试验证逐 Session 的策略读取与继承。
+
+## 考虑过的替代方案
+
+**保留 `Context.agent`。** 反向 accessor 会让注册所有权看起来等同于操作身份，还要求每个 Context 派生、适配器和测试替身保留一项与 Cordis 服务选择或 effect 清理无关的关联。
+
+**从调用方 Context 推断运行时归属。** 私有管理器 Context、Agent Context 和常驻 preset Context 都能调用同一个工厂。因此，Context 祖先关系无法说明由哪个存活 Agent 拥有结果；创建方必须把它已知的父级放进请求 options。
+
+**分类 Agent 作用域键。** 不透明作用域键表达路由成员关系，而不是领域身份。分类该键会让 Agent 成为组合中心，也仍会把插件的 effect 所有者与策略所需的 Session 耦合起来。
+
+**使用发起 Agent 作为创建归属。** 发起方作用域记录异步执行的因果关系，而非生命周期归属。父级可能发起有意创建根级 Agent 的工作，而 setup 仍位于子级驱动边界之外。
+
+**使用持久化会话谱系。** `parentSession` 跨进程生命周期记录对话祖先关系。运行时归属控制存活根级和 teardown，因此把二者等同会阻止合法恢复的 fork 成为顶层 Agent。
+
+## 后果
+
+生命周期 options、事件、服务请求和传输请求会携带显式 Agent 身份，因此每项操作都会声明自身使用的身份，TypeScript 也会检查两侧。Context 可以继续复用于依赖访问与 effect 所有权，而不会成为另一种领域对象定位器。
+
+可续跑子级与一次性进程内子级使用同一种运行时父级关系。仅限根级的消费方会排除这些子级，父级 teardown 可以依据唯一的存活归属图推理，而持久化谱系仍可描述历史，不必承担进程内生命周期语义。

+# Agent Note: Follow package-local forwarding modules in Typert references
+
+Status: implemented
+
+English | [中文](2026-09-07-typert-package-local-forwarding-imports.zh.md)
+
+## Problem
+
+`WorkspaceAnalyzer` resolves every type reference to its original declaration before classifying it, then reads only the referencing file's own `import` statement to decide whether the reference crossed a package through a public export. A package that re-exports another package's type from one of its own modules, and imports that module by relative path elsewhere, therefore fails with `crosses a package without an explicit package import` although the package import exists one hop away. The failure is deterministic for every batch size and package order; it surfaces in whichever analysis selects the referencing package as a root, which is why [issue 3525](https://github.com/deepseek-harness/deepseek-harness/issues/3525) observed it as batch-dependent.
+
+## Decision
+
+[`targetForReference`](../../../../packages/typert/generator/src/analyzer.ts) resolves a relative specifier through the face's shared compiler host and module-resolution cache and follows it only while the resolved file stays inside the referencing package. In each forwarding module it collects the `export` edges that carry the requested name: a named re-export with a specifier, an `export { local }` backed by that module's `import`, and star re-exports whose module exports the same symbol. Explicit edges are tried before star edges, matching TypeScript's shadowing of star exports, and each resolved module and requested export-name pair is entered once, so circular star re-exports terminate while distinct renamed routes through one module remain available. The walk stops at the first package specifier and feeds that identity and export name to the existing `packageExportName` check, so a forwarded type must still be public at the package subpath the forwarding module names, and a package name without a registration is refused there. The reference model is unchanged: the target remains `declaration` for a same-face owner and `cross-face` for another face.
+
+The walk yields no package import, and the reference fails as before, when a relative specifier resolves outside the referencing package, when the only edge carrying the name is a namespace re-export or a re-exported namespace import, or when every edge loops back to a module and requested-name pair already entered.
+
+## Alternatives considered
+
+**Treat a relative import whose alias chain ends in another package as implicitly public.** Rejected: it would accept `../../other/src/file.ts` and any forwarding module that itself reaches the other package by relative path, removing the public-export check the generated Remote declarations rely on to name an importable subpath.
+
+**Record the forwarding module as the reference target.** Rejected: emitters and cross-face links need the original declaration's package and public subpath; a package-local module has no public identity of its own.
+
+**Select edges in source order without symbol checks.** Rejected: a star re-export that loops back to an earlier module can precede the explicit re-export that actually carries the type, and TypeScript itself lets explicit exports shadow star exports; ordering explicit edges first and continuing past an entered module and requested-name pair keeps such modules accepted without an unbounded walk.
+
+**Make batched and whole-workspace analysis select the same roots.** Rejected as a fix: root selection does not change the verdict on a reference, only whether the reference is visited, so aligning the callers would hide the incorrect classification rather than remove it.
+
+## Consequences
+
+Packages may keep one forwarding module for foreign types and import it relatively, matching how their own modules are organized. Each cross-package relative reference costs one module resolution per hop through the face's shared resolution cache; `reachableFiles` now resolves through the same cache. [`type-model.spec.ts`](../../../../packages/typert/generator/tests/type-model.spec.ts) pins named, renamed multi-hop, import-then-export, star, and namespace-import forwarding, an explicit re-export beside a looping star edge, distinct renamed routes through one shared module, a forwarded private export, a forwarding module that crosses by relative path, a cycle whose only exit crosses by relative path, a namespace re-export, a re-exported namespace import, cross-face forwarding, and equality of whole and batched analysis for the forwarding fixture across batch sizes and package orders.

+# Agent Note: Typert 引用追踪包内转发模块

+Status: implemented

+[English](2026-09-07-typert-package-local-forwarding-imports.md) | 中文
+
+## Problem
+
+`WorkspaceAnalyzer` 先把每个类型引用解析到原始声明再分类，然后只读引用所在文件自己的 `import` 语句来判断该引用是否经由公开导出跨包。一个包若在自己的某个模块里重新导出另一个包的类型，并在别处用相对路径导入该模块，就会报 `crosses a package without an explicit package import`，尽管包导入只隔一跳。这个失败在任何批次大小和包顺序下都会稳定出现；它出现在哪次分析里，取决于哪次分析把引用方的包选为根，因此 [issue 3525](https://github.com/deepseek-harness/deepseek-harness/issues/3525) 观察到的现象像是与批次相关。
+
+## Decision
+
+[`targetForReference`](../../../../packages/typert/generator/src/analyzer.ts) 通过该 face 共享的编译器宿主及其模块解析缓存来解析相对说明符，且只在解析到的文件仍位于引用方包内时继续追踪。在每个转发模块里，它收集承载所请求名字的 `export` 边：带说明符的具名重新导出、由该模块自身 `import` 支撑的 `export { local }`，以及导出同一符号的星号重新导出。显式边先于星号边尝试，与 TypeScript 中显式导出遮蔽星号导出的规则一致；解析后的模块与请求导出名组成的每个组合只进入一次，因此循环的星号重新导出能够终止，经同一模块转发的不同改名路径仍可继续尝试。追踪在遇到第一个包说明符时停止，并把该包身份和导出名交给现有的 `packageExportName` 检查，因此被转发的类型仍必须在转发模块所写的包子路径上公开，没有登记的包名也在此被拒绝。引用模型不变：同 face 的所有者仍是 `declaration`，另一 face 仍是 `cross-face`。
+
+当相对说明符解析到引用方包之外、承载该名字的唯一边是命名空间重新导出或被重新导出的命名空间导入，或所有边都回到已进入的模块与请求名组合时，追踪得不到包导入，引用照旧失败。
+
+## Alternatives considered
+
+**把别名链终点在另一个包的相对导入视为隐式公开。** 已拒绝：这会接受 `../../other/src/file.ts`，也会接受自身用相对路径抵达另一个包的转发模块，从而取消公开导出检查，而生成的 Remote 声明依赖该检查来命名可导入的子路径。
+
+**把转发模块记为引用目标。** 已拒绝：发射器和跨 face 链接需要原始声明的包和公开子路径，包内模块没有自己的公开身份。
+
+**按源码顺序选边且不校验符号。** 已拒绝：回到更早模块的星号重新导出可能排在真正承载该类型的显式重新导出之前，而 TypeScript 本身允许显式导出遮蔽星号导出；显式边优先并跳过已进入的模块与请求名组合，既能接受这类模块，又不会无限追踪。
+
+**让分批分析与全工作区分析选择相同的根。** 作为修复方案已拒绝：根的选择不改变对一个引用的判定，只决定该引用是否被访问，对齐调用方只会掩盖错误分类，不能消除它。
+
+## Consequences
+
+包可以为外部类型保留一个转发模块并用相对路径导入它，与自身模块的组织方式一致。每个跨包相对引用每跳付出一次经该 face 共享解析缓存的模块解析；`reachableFiles` 现在也通过同一缓存解析。[`type-model.spec.ts`](../../../../packages/typert/generator/tests/type-model.spec.ts) 固定了具名、改名多跳、先导入再导出、星号和命名空间导入这几种转发，与回环星号边并存的显式重新导出，经同一模块转发的不同改名路径，被转发的私有导出，用相对路径跨包的转发模块，唯一出口用相对路径跨包的循环，命名空间重新导出，被重新导出的命名空间导入，跨 face 转发，以及转发 fixture 在不同批次大小和包顺序下全量分析与分批分析相等。

+# Agent Note: Session prose local media paths display through a same-origin file route
+
+Status: implemented
+
+English | [中文](2026-09-07-session-prose-local-media-display.zh.md)
+
+## Problem
+
+Assistant prose can reference an image by its filesystem path, but browsers cannot read Host files. A renderer limited to absolute HTTP(S) destinations leaves those references as inert alt text. Issue #3662 records this display gap.
+
+## Decision
+
+Local media paths in Session prose render through a same-origin file route. This note owns the renderer vocabulary and its placement; [authenticated filesystem reads](2026-09-08-file-display-through-filesystem.md) owns the current serving policy and supersedes the workspace/media restrictions described below.
+
+`ui-primitives` owns the `MarkdownPathImages` vocabulary on `MarkdownText`. Like `fileMentions`, it applies only after a message settles so frozen streaming blocks cannot cache a vocabulary handler. The settled pass rewrites image destinations outside the remote-URL allowlist and emits only absolute `http(s)`, `blob`, or `data` results. Without a vocabulary, local destinations retain inert alt text. Failed loads replace the image with authored alt text, or its original destination when alt is empty; a different source can load again.
+
+`ui-chat` supplies a page-stable `localPathMediaUrl` vocabulary through `AssistantMarkdown`. It maps absolute POSIX paths to `/api/file?path=…` on the page's origin. Relative and protocol-relative paths, Windows-style paths, and non-HTTP page transports such as Electron `file://` remain inert.
+
+`session-controller` owns the `SessionMediaReferences` contribution beside `SessionFileReferences`. It registers through `connection.fetch`, which applies the same browser authentication and trust checks as `/api` RPC. The fixed same-origin endpoint gives the synchronous renderer a stable URL without an asynchronous capability negotiation.
+
+## Alternatives considered
+
+**Typert gateway or workspace controller ownership.** The gateway owns Remote RPC dispatch, while the workspace controller owns registry lifecycle. Neither owns file-byte presentation; Session Controller is the consumer serving Session prose.
+
+**Session RPC followed by blob/data URLs.** Attachment images can use an asynchronous fetch, but this Markdown vocabulary must synchronously resolve a destination during a memoized render pass.
+
+**Image-only endpoints.** One file route can serve images, audio, and video without separate URL vocabularies. The current implementation returns complete bounded files; Markdown audio/video player nodes remain independent work.
+
+**Byte-signature validation in the route.** The model-facing `read_image` tool owns image admission checks. Display responses describe content by MIME lookup and let browser decoding reject corrupt payloads, avoiding a duplicate signature checker.
+
+**Workspace/media-only access (superseded).** The original policy restricted canonical paths to registered workspace roots and allowed image/video/audio MIME categories except SVG. Regular-file checks before opening rejected pipes and devices; an opened-handle identity comparison narrowed replacement races. These restrictions bounded authenticated access and avoided a per-request interactive authorization flow. They also excluded temporary screenshots and remote files; the successor note records the replacement policy and why those restrictions are not retained.
+
+## Consequences
+
+The Client vocabulary cannot bypass Host authentication or the filesystem provider. The original restricted route distinguished an existing outside-workspace path from an absent path, exposing existence even while refusing its bytes; the successor policy instead permits ordinary provider-readable files.
+
+Windows-style authored paths remain unsupported by the Client vocabulary. Trajectory and tool-card Markdown consumers do not supply this vocabulary, and audio/video Markdown nodes do not render players. These are renderer limitations, independent of the file route's readable MIME types.
+
+The archived [model-readable image paths](../../archived/feature/2026-08-21-model-readable-image-paths.md) note owns the model-facing behavior; this note owns user-facing display and does not supersede it.
+
+## Testing
+
+Renderer tests cover settled and streaming gates, reference-style images, protocol rechecks, failed-load fallback, and replacement sources. Chat tests cover the vocabulary and component wiring. The browser scenario in `apps/web/tests/markdown-images.e2e.ts` boots the shipped Web composition with a seeded Session and checks actual loading and fallback text. A model-driven recorded Session round trip remains separate from this UI expectation; the successor note names current route coverage.

+
+## Problem
+
+Assistant 正文可能通过文件系统路径引用图片，但浏览器无法读取 Host 文件。仅允许绝对 HTTP(S) 目标的渲染器会把这些引用保留为静态 alt 文本。Issue #3662 记录了这一展示缺口。
+
+## Decision
+
+Session 正文中的本地媒体路径通过同源文件路由渲染。本记录拥有渲染器词表及其归属；[鉴权文件系统读取](2026-09-08-file-display-through-filesystem.zh.md)拥有当前文件服务策略，并取代下文的工作区与媒体限制。
+
+`ui-primitives` 拥有 `MarkdownText` 上的 `MarkdownPathImages` 词表。与 `fileMentions` 一样，它只在消息稳定后生效，使冻结的流式块无法缓存词表处理函数。稳定渲染过程重写远程 URL 白名单之外的图片目标，并只输出绝对 `http(s)`、`blob` 或 `data` 结果。没有词表时，本地目标保留静态 alt 文本。加载失败会把图片替换为作者提供的 alt 文本；alt 为空时显示原始目标路径；不同来源仍可重新加载。
+
+`ui-chat` 通过 `AssistantMarkdown` 提供页面稳定的 `localPathMediaUrl` 词表。它把绝对 POSIX 路径映射到页面同源的 `/api/file?path=…`。相对路径、协议相对路径、Windows 风格路径，以及 Electron `file://` 等非 HTTP 页面传输保持静态回退。
+
+`session-controller` 在 `SessionFileReferences` 旁拥有 `SessionMediaReferences` 贡献。它通过 `connection.fetch` 注册；该通道执行与 `/api` RPC 相同的浏览器鉴权和信任检查。固定同源端点让同步渲染器获得稳定 URL，无需异步能力协商。
+
+## Alternatives considered
+
+**由 Typert gateway 或 workspace controller 拥有。** gateway 拥有 Remote RPC 分发，workspace controller 拥有注册表生命周期。两者都不拥有文件字节展示；Session Controller 是服务 Session 正文的消费方。
+
+**先经 Session RPC 获取，再使用 blob/data URL。** 附件图片可以异步获取，但此 Markdown 词表必须在记忆化渲染过程中同步解析目标。
+
+**图片专用端点。** 单一文件路由即可服务图片、音频和视频，无需独立 URL 词表。当前实现返回有界完整文件；Markdown 音视频播放器节点仍是独立工作。
+
+**路由中的字节签名校验。** 面向模型的 `read_image` 工具拥有图片准入检查。展示响应通过 MIME 查询描述内容，由浏览器解码拒绝损坏载荷，避免重复实现签名检查器。
+
+**仅限工作区与媒体的访问（已取代）。** 原策略把规范路径限制在已注册工作区根目录内，并允许除 SVG 外的 image/video/audio MIME 类别。打开前的普通文件检查拒绝管道与设备；已打开句柄的身份比较收窄替换竞态。这些限制约束了鉴权后的访问范围，并避免每次请求的交互授权流程。它们也排除了临时截图与远程文件；后续记录说明替代策略及不保留这些限制的理由。
+
+## Consequences
+
+客户端词表无法绕过 Host 鉴权或文件系统提供方。原受限路由区分了工作区外已存在路径与缺失路径，即使拒绝其字节仍暴露存在性；后续策略则允许提供方可读的普通文件。
+
+客户端词表仍不支持作者提供的 Windows 风格路径。轨迹与工具卡片 Markdown 消费方不提供此词表，音视频 Markdown 节点也不渲染播放器。这些属于渲染器限制，与文件路由可读的 MIME 类型无关。

+# Agent Note: Authenticated file display reuses filesystem byte reads
+
+Status: implemented
+
+English | [中文](2026-09-08-file-display-through-filesystem.zh.md)
+
+## Problem
+
+Session prose can reference screenshots in temporary directories or files stored by a remote filesystem provider. A Host-local workspace allowlist cannot serve those paths. An image response without a byte limit can also make the browser download a 1 GiB image before attempting to decode it.
+
+## Decision
+
+The authenticated `/api/file` route reads ordinary files through `ctx.fs`. Authentication and the composed provider's read policy govern access; directory and MIME allowlists do not. This supersedes the serving policy in [the local-media display note](2026-09-07-session-prose-local-media-display.md), which retains renderer ownership and its rationale.
+
+GET calls the existing `readBytes(target, signal, maxBytes)`: providers reject known oversized files before content I/O and enforce the limit while reading. HEAD uses metadata without reading content. `FS_TOO_LARGE` becomes 413. MIME lookup supplies response metadata without sniffing file contents; unknown extensions use `application/octet-stream`. A sandbox CSP prevents directly opened HTML/SVG from executing with the authenticated API origin.
+
+All files use the resolved `ctx.attachments.imageLimits.maxImageBytes` limit, normally 20 MiB. The attachment service owns this deployment setting. All responses contain complete files; Range is ignored and no range support is advertised.
+
+## Alternatives considered
+
+**Workspace and media allowlists.** They limit which authenticated bytes can be read, but exclude ordinary screenshot locations and remote files. The chosen policy permits every regular file the composed provider can read.
+
+**A new filesystem byte-stream API.** Efficient large-file delivery and audio/video seeking would require implementations in every provider, including remote range handling. Complete bounded reads satisfy the current display scope without widening that interface. Streaming and Range can be added when those use cases justify the provider work.
+
+**Duplicate size checks in the route.** GET needs no additional stat/read loop: `readBytes` already owns preflight limits, growth detection, and cancellation. HEAD checks size separately because it must not read the body.
+
+## Consequences
+
+Temporary and remote files use the same filesystem provider as `read_image`, without adding model-facing events. The local sandbox provider constrains mutations and permits reads; an authenticated client therefore has broader access than registered workspace roots. Files remain subject to the provider's permissions and the route's byte limits.
+
+Each GET buffers the complete file in Host memory. Audio/video work as complete responses without incremental transfer or guaranteed seeking. Encoded byte limits do not bound decoded pixel dimensions. Failed image loads show authored alt text or the original destination when alt is empty.
+
+## Testing
+
+Route tests cover sparse 1 GiB rejection before content I/O, post-stat growth, the shared attachment byte limit, ordinary MIME types, temporary paths and symlinks, opaque remote targets, provider failures, metadata-only HEAD, ignored Range, and disposal. Browser expectations cover rendered images, 413/404 and corrupt-image fallbacks, and an image outside the workspace. Remote byte transfer remains owned by the existing filesystem provider tests.

+
+[English](2026-09-08-file-display-through-filesystem.md) | 中文
+
+## Problem
+
+会话正文可能引用临时目录中的截图或远程文件系统提供方中的文件。Host 本地工作区白名单无法提供这些路径。没有字节上限的图片响应还可能让浏览器先下载一张 1 GiB 图片，再尝试解码。
+
+## Decision
+
+鉴权 `/api/file` 路由通过 `ctx.fs` 读取普通文件。鉴权和所组合提供方的读取策略决定访问权限；目录与 MIME 白名单不参与准入。这取代了[本地媒体展示记录](2026-09-07-session-prose-local-media-display.zh.md)中的文件服务策略；该记录保留渲染器归属及其理由。
+
+GET 调用现有 `readBytes(target, signal, maxBytes)`：提供方在内容 I/O 前拒绝已知超限文件，并在读取过程中执行上限。HEAD 使用元数据，不读取内容。`FS_TOO_LARGE` 转换为 413。MIME 查询提供响应元数据，不嗅探文件内容；未知扩展名使用 `application/octet-stream`。sandbox CSP 阻止直接打开的 HTML/SVG 以鉴权 API 源身份执行脚本。
+
+所有文件均使用已解析的 `ctx.attachments.imageLimits.maxImageBytes` 上限，通常为 20 MiB。附件服务拥有此部署配置。所有响应均包含完整文件；忽略 Range，也不声明支持 Range。
+
+## Alternatives considered
+
+**工作区和媒体白名单。** 它们限制鉴权后能读取哪些字节，却排除了常见截图位置和远程文件。所选策略允许读取所组合提供方可读的任意普通文件。
+
+**新增文件系统字节流 API。** 高效的大文件传输和音视频跳转需要每个提供方实现，包括远端 Range 处理。有界完整读取满足当前展示范围，无需扩展该接口。相关用例足以支持这项提供方工作时，可以加入流式传输与 Range。
+
+**在路由重复实现大小检查。** GET 无需额外的 stat/read 循环：`readBytes` 已经负责读取前上限、增长检测和取消。HEAD 单独检查大小，因为它不能读取正文。
+
+## Consequences
+
+临时与远程文件使用与 `read_image` 相同的文件系统提供方，不增加模型可见事件。本地沙箱提供方约束变更操作并允许读取，因此鉴权客户端的访问范围大于已注册工作区根目录。文件仍受提供方权限和路由字节上限约束。
+
+每个 GET 都会在 Host 内存中缓存完整文件。音视频使用完整响应，不支持增量传输，也不保证跳转播放。编码字节上限不限制解码后的像素尺寸。图片加载失败后展示作者提供的 alt 文本；alt 为空时展示原始目标路径。
+
+## Testing
+
+路由测试覆盖内容 I/O 前拒绝稀疏 1 GiB 文件、stat 后增长、共用附件字节上限、普通 MIME 类型、临时路径与符号链接、不透明远程目标、提供方失败、仅元数据 HEAD、忽略 Range 和释放。浏览器期望覆盖图片渲染、413/404 及损坏图片回退，以及工作区之外的图片。远程字节传输仍由现有文件系统提供方测试负责。

[Agent Notes](../../README.md) remain outside this structural contract. Every human-facing document is a tutorial with an ordered outcome or a reference with an explicit lookup scope; a [postmortem](../../../../docs/postmortem/README.md) is an incident-scoped reference whose chronology records evidence.

The published user guide starts with tasks inside the running Web UI, then links to distinct tutorials or reference owners for other interfaces, plugin development, and advanced configuration instead of repeating Web startup.

 - **Ceilings are an enforcement frontier that ratchets.** A doc at or below its target keeps at least 5% headroom as its ceiling ratchets down; a doc above target keeps a frozen ceiling that prevents growth until it reaches the target (root `AGENTS.md` ≤ 1,600 words; `architecture.md` ≤ 1,800; subtree `AGENTS.md` ≤ 600 except `packages/AGENTS.md` ≤ 650 and `docs/AGENTS.md` ≤ 1,250; `packages/README.md` ≤ 600).

- **A broad gate over every doc tier** — rejected: a blanket ceiling punishes exactly the right kind of long doc (a feature matrix or type catalog where every row is a fact) and generates per-file override churn that trains contributors to rubber-stamp raises.

+# Agent Note: Exclude documentation and comment-only changes from review routing
+
+Status: implemented
+
+English | [中文](2026-09-08-comment-only-review-routing.zh.md)
+
+## Problem
+
+Directory ownership alone treats documentation and comment edits like executable changes. These edits do not require the automatic code-owner request that protects behavior changes.
+
+GitHub may omit or truncate a file patch. A scanner that assumes every patch is complete can miss executable changes that occur outside the supplied hunks.
+
+## Decision
+
+Review routing classifies every old and new path in this order: test, documentation, comment-only, then reviewable code. Test classification wins when a test path also has a documentation extension. Every filename ending in `.md` or `.yaml`, matched without case sensitivity, is documentation. A `.yml` file is not documentation under this rule.
+
+Comment-only classification applies only to files with `status: modified` and a declared source-comment syntax. The scanner reconstructs the before and after text for each patch hunk, removes comments outside quoted strings, removes empty lines left by comments, and requires the remaining text to be identical.
+
+The scanner counts added and deleted patch lines and compares them with GitHub's file record before accepting a comment-only result. A missing patch, a count mismatch, a rename, an unsupported extension, or a comment form that remains visible to the lexer keeps the file reviewable. This fail-safe result can request an unnecessary review but cannot suppress a known code change.
+
+The supported lexical rules cover C-style line and block comments, hash comments, SQL comments, CSS block comments, and HTML comments for an explicit extension set in the scanner. Comment directives such as JSDoc tags, lint controls, compiler controls, and coverage controls are comments for routing purposes.
+
+## Verification
+
+[Scanner tests](../../../../.github/review-ownership/request-review.test.mjs) cover documentation extensions, supported comment forms, quoted comment markers, executable token changes, incomplete patches, renames, unsupported extensions, exclusion precedence, and the no-request result when every file is excluded.
+
+## Alternatives considered
+
+**Keep every non-test file reviewable.** This requests code owners for documentation and comment maintenance even though the routing policy is intended to identify executable changes.
+
+**Infer arbitrary semantic equivalence.** Proving behavior equivalence across the repository's languages requires language toolchains and still cannot assign one stable meaning to generated files, configuration, or build directives. The scanner performs only lexical comment removal.
+
+**Trust every patch returned by GitHub.** GitHub can omit or truncate patches. Matching the patch's added and deleted line counts to the file record prevents a partial patch from producing a comment-only verdict.
+
+**Fetch and parse every complete file revision.** Per-file content requests multiply API traffic for large pull requests and still require the same language-specific parsing. The changed-file response already carries enough evidence for complete ordinary patches.
+
+## Consequences
+
+Documentation and proven comment-only changes request nobody. The workflow logs them separately from tests so maintainers can audit why owner matching ignored a file.
+
+Unsupported or incomplete inputs remain reviewable. Comment directives do not request owners even when another tool interprets them, because this policy classifies their lexical form rather than downstream tool behavior.

+
+Status: implemented
+
+[English](2026-09-08-comment-only-review-routing.md) | 中文
+
+## 问题
+
+只按目录分配 owner 会把文档和注释编辑视为可执行变更。这些编辑不需要用于保护行为变更的自动代码 owner 请求。
+
+GitHub 可能省略或截断文件 patch。如果扫描器假定每个 patch 都完整，就可能漏掉位于已提供 hunk 之外的可执行变更。
+
+## 决策
+
+评审路由按测试、文档、纯注释、可评审代码的顺序对每个新旧路径分类。当测试路径同时具有文档扩展名时，测试分类优先。所有以 `.md` 或 `.yaml` 结尾的文件均视为文档，扩展名匹配不区分大小写；此规则不把 `.yml` 文件视为文档。
+
+纯注释分类只适用于 `status: modified` 且已声明源码注释语法的文件。扫描器重建每个 patch hunk 的变更前后文本，移除引号字符串外的注释和注释留下的空行，并要求其余文本完全相同。
+
+扫描器会统计 patch 的新增行和删除行，并在接受纯注释结果前与 GitHub 文件记录比较。缺失 patch、计数不符、重命名、不受支持的扩展名，或词法分析器仍能看到的注释形式都会使文件保持可评审状态。该保守结果可能产生不必要的评审请求，但不会隐藏已知代码变更。
+
+受支持的词法规则按扫描器中显式的扩展名集合覆盖 C 风格行注释和块注释、井号注释、SQL 注释、CSS 块注释及 HTML 注释。JSDoc 标签、lint 控制、编译器控制和覆盖率控制等注释指令在评审路由中仍属于注释。
+
+## 验证
+
+[扫描器测试](../../../../.github/review-ownership/request-review.test.mjs)覆盖文档扩展名、受支持的注释形式、引号内的注释标记、可执行 token 变更、不完整 patch、重命名、不受支持的扩展名、排除优先级，以及所有文件均被排除时不发出请求的结果。
+
+## 考虑过的替代方案
+
+**让每个非测试文件都保持可评审。** 这会为文档和注释维护请求代码 owner，但该路由策略的目标是识别可执行变更。
+
+**推断任意语义等价。** 证明仓库中多种语言的行为等价需要各语言工具链，而且仍然无法为生成文件、配置或构建指令提供一种稳定含义。扫描器只执行词法注释移除。
+
+**信任 GitHub 返回的每个 patch。** GitHub 可能省略或截断 patch。将 patch 的新增和删除行数与文件记录匹配，可以防止不完整 patch 产生纯注释结论。
+
+**获取并解析每个文件的完整修订版本。** 对于大型 PR，逐文件内容请求会增加多倍 API 流量，而且仍需相同的语言专用解析。普通完整 patch 所需的证据已包含在变更文件响应中。
+
+## 后果
+
+文档和确认的纯注释变更不会请求任何人。Workflow 会将它们与测试分开记录，以便维护者检查 owner 匹配忽略文件的原因。
+
+不受支持或不完整的输入仍需评审。即使其他工具会解释注释指令，这些指令也不会请求 owner，因为该策略按词法形式分类，而不是按下游工具行为分类。

+# Agent Note: Route reviews from trusted changed-file policy
+
+Status: implemented
+
+## Problem
+
+GitHub's native CODEOWNERS behavior requests reviewers whenever a matching path changes. It cannot apply this repository's distinction between reviewable implementation or documentation files and test-only evidence. A native CODEOWNERS file also makes GitHub, rather than an inspected repository program, responsible for the request decision.
+
+Review routing needs an observable changed-file input, explicit owner rules, complete test exclusions, and a write-capable workflow that remains safe for pull requests from forks.
+
+## Decision
+
+The repository keeps a CODEOWNERS-compatible map at [`.github/review-ownership/CODEOWNERS`](../../../../.github/review-ownership/CODEOWNERS), outside GitHub's native CODEOWNERS locations. The map accepts only explicit absolute directory patterns with one or two individual GitHub users. It rejects wildcards, hidden-directory patterns, teams, more than two owners, duplicate patterns, and duplicate owners. Later matching patterns replace earlier matches.
+
+The policy test counts non-test tracked lines in directories that match an ownership rule. It rejects a map in which `@turtle1999` owns more than one third of that eligible owned codebase.
+
+The [`request-review` workflow](../../../../.github/workflows/request-review.yml) runs on `pull_request_target` events for opened, synchronized, reopened, ready-for-review, and converted-to-draft pull requests. Its write-capable job checks out the default branch and executes only the default branch's scanner and ownership map. It does not check out pull-request code or read repository secrets.
+
+The scanner fetches every changed-file record before deciding. It fails if the pull request reports more than GitHub's 3,000-file API limit or if pagination returns an incomplete list. It normalizes repository paths, evaluates old and new paths of a rename independently, and escapes filenames before logging them.
+
+The scanner excludes test-only paths before owner matching. Excluded paths comprise directories named `test`, `tests`, `__tests__`, `__snapshots__`, `benches`, or `stress-tests`; the top-level `benchmarks` and `snapshots` trees; `packages/test-support`; `scripts/fixtures` and `scripts/snapshots`; filenames ending in `.bench.<ext>`, `.corpus.<ext>`, `.e2e.<ext>`, `.perf.<ext>`, `.snapshot.<ext>`, `.spec.<ext>`, `.stress.<ext>`, or `.test.<ext>`; and Python `test_*.py`, `*_test.py`, or `*_tests.py` files. Test infrastructure such as `vitest*.config.ts` and gate implementations remains reviewable because it changes how repository evidence is produced. The [comment-only routing decision](2026-09-08-comment-only-review-routing.md) owns the additional documentation and comment exclusions.
+
+The workflow prints the changed code paths, each exclusion class, per-file owner matches and changed LOC, aggregate owner relevance, approved owners omitted from new requests, current individual requests, the available counted slot after planned cancellations, and final reviewer actions before any review-request mutation. For a non-draft pull request, it fetches the complete chronological review list and reduces each owner's undismissed `APPROVED` and `CHANGES_REQUESTED` reviews to the latest decisive state; `COMMENTED` and `PENDING` reviews leave that state unchanged. It removes the pull-request author, owners with an active approval, and users who remain requested from the matched individual owners. An active approval remains sufficient after later synchronize events, while a later changes-requested review makes the owner eligible again. The review-list operation fails before mutation at 3,000 entries or on an invalid record.
+
+The workflow keeps at most one current individual review request other than `@turtle1999`. An existing request for `@turtle1999` does not consume that slot, but each workflow run adds at most one reviewer. An existing non-turtle request leaves no slot, so the workflow does not add anyone, including `@turtle1999`. Existing individual requests consume the slot even when they do not match the ownership map. An owner's relevance is the sum of GitHub-reported additions and deletions for each reviewable changed-file record whose current or previous path matches that owner. Each record contributes once per owner, including when both paths of a rename match the same owner. Higher changed LOC selects candidates first when the available slot cannot cover the remaining owners; login order resolves equal scores.
+
+When current review requests exist, the workflow reads the complete review-request timeline before mutation. A current reviewer is workflow-authored only when its latest matching `review_requested` event identifies `github-actions[bot]` as `review_requester`; a request without an attributable event is preserved. A non-draft run cancels workflow-authored reviewers that no longer match the current candidates and excess workflow-authored non-turtle reviewers above the counted limit; current relevance order selects which matching workflow reviewer remains. Planned cancellations release capacity before the workflow selects a new reviewer. A draft run cancels every current workflow-authored request. Requests made by people remain unchanged. An attributable event with invalid provenance and timelines above 3,000 events fail before mutation.
+
+## Verification
+
+[Scanner tests](../../../../.github/review-ownership/request-review.test.mjs) cover admitted ownership syntax, rejected syntax, each exclusion class, production-name negative controls, renames, last-match behavior, unmatched files, changed-LOC aggregation and ranking, complete pagination, file and review limits, approval-state reduction, approved-owner suppression and next-owner selection, log-before-mutation ordering, author and existing-reviewer filtering, non-draft reconciliation, draft cancellation provenance, and API failures. [Workflow tests](../../../../scripts/ci-workflow.spec.ts) pin the event set, least permissions, trusted default-branch checkout, absence of pull-request-head references and secrets, and executed command. The gate graph includes both suites in static CI and `check-all`.
+
+## Alternatives considered
+
+**Use native CODEOWNERS.** Native routing cannot ignore test-only changes and offers no repository-owned decision log before requesting reviewers.
+
+**Run under `pull_request` and check out the pull-request head.** A fork workflow does not receive a write-capable token, while granting a write token to code from an untrusted head is unsafe.
+
+**Execute the pull request's scanner or owner map under `pull_request_target`.** This lets an untrusted pull request choose its own write-capable behavior or owners.
+
+**Select capped candidates by login order.** Login order is stable but ignores how much reviewable code changed under each owner's directories. Changed LOC makes the limited requests follow the pull request's strongest ownership relevance while retaining login order for ties.
+
+**Cancel every reviewer that no longer matches.** A person may request a reviewer for reasons outside the ownership map. Only requests attributed to the workflow identity are safe for automated reconciliation.
+
+**Treat an empty current request as an owner who still needs review.** GitHub removes the pending request when the reviewer submits a review. Requesting an owner with an active approval again adds no ownership coverage and creates repeated notifications after later synchronize events.
+
+**Infer arbitrary semantic source changes from patches or language parsers.** GitHub can omit or truncate patches, and the repository spans many languages. The scanner does not try to prove that two programs behave identically. The later [comment-only routing decision](2026-09-08-comment-only-review-routing.md) adds a narrow lexical comparison only when changed-line counts prove that GitHub supplied the complete patch.
+
+## Consequences
+
+Reviewer mutations are reproducible from a trusted policy, the file classifications printed in the workflow log, and review-request provenance in the pull-request timeline. Excluded changes do not request owners, rule and changed-file updates remove obsolete workflow-authored requests on the next run, and draft pull requests do not retain workflow-authored requests. Ownership changes become effective only after merge, so the pull request that changes policy cannot apply its untrusted policy to itself.
+
+The workflow requests at most one reviewer per run, does not repeat a request while that owner has an active approval, keeps no more than one current individual reviewer other than `@turtle1999`, and prefers owners whose matched reviewable files carry more changed LOC. An existing `@turtle1999` request leaves the counted slot available; an existing non-turtle request prevents every additional request. Shared ownership gives each owner the same file-level relevance without counting one renamed file twice for the same owner. GitHub-generated review-request events may not start other workflows that depend on recursively triggered events from `GITHUB_TOKEN`; those workflows must not rely on this request as their only trigger.
+
+Any change that does not match an explicit exclusion remains eligible under an owned directory. Unmatched paths are logged and request nobody. Pull requests above the file, review, or timeline API limit fail without applying a partial reviewer mutation.

+# Automated review requests
+
+## Summary
+
+The [`request-review` workflow](../workflows/request-review.yml) reads the CODEOWNERS-compatible [ownership map](CODEOWNERS) from the trusted default branch. It classifies changed files, requests missing owners for reviewable code, and cancels its outstanding requests when a pull request becomes a draft. The ownership map is outside GitHub's native CODEOWNERS locations, so GitHub does not apply it directly.

+<a id="routing"></a>
+
+## Routing
+
+Pull requests run the workflow when opened, synchronized, reopened, marked ready for review, or converted to a draft. The scanner fetches the complete pull-request file list, evaluates both paths of a rename, and fails instead of routing from a partial list. GitHub exposes at most 3,000 files for this API.
+
+For a non-draft pull request, the workflow keeps at most one current individual review request other than `@turtle1999`; an existing request for `@turtle1999` does not consume that slot. Each run adds at most one reviewer. An existing non-turtle request leaves no slot, so the workflow does not add anyone, including `@turtle1999`. Existing individual requests consume the slot even when made by people outside the ownership map. When more candidates remain than the available counted slot can cover, the workflow ranks them by the total GitHub-reported additions plus deletions in reviewable changed-file records that match each owner. A rename contributes its changed LOC once to an owner even when both paths match that owner. Higher changed LOC ranks first, and login order resolves ties.
+
+Before selecting a new reviewer, a non-draft run fetches the pull request's complete chronological review list. An owner's latest undismissed decisive review is `APPROVED` or `CHANGES_REQUESTED`; comments and pending reviews do not replace that decision. An approved owner remains omitted after later synchronize events, while a later changes-requested review makes the owner eligible again. The workflow fails before mutation when the list reaches the supported 3,000-review limit or contains an invalid record.
+
+On every run with current review requests, the workflow reads the pull-request timeline. A current reviewer is workflow-authored only when the latest matching `review_requested` event names `github-actions[bot]` as `review_requester`; a request without an attributable event is preserved. On a non-draft pull request, the workflow cancels workflow-authored reviewers that no longer match the current candidates and excess workflow-authored non-turtle reviewers above the counted limit. Current relevance order decides which matching workflow reviewer remains when the limit shrinks. It then fills any slot left by the planned cancellations. On a draft, it cancels every current workflow-authored request. Requests made by people remain unchanged in both states. An attributable event with invalid provenance fails before mutation, and the workflow also fails without cancellation when the timeline exceeds 3,000 events.
+
+The ownership map accepts explicit absolute directory patterns and one or two individual GitHub users per pattern. It rejects wildcards, hidden-directory patterns, teams, more than two owners, and duplicate patterns or owners. Matching follows CODEOWNERS last-match semantics. The scanner prints the changed code, excluded test, documentation, and comment-only files; per-file owner matches and LOC; the aggregate owner relevance ranking; approved owners omitted from new requests; current individual requests and the available counted slot after planned cancellations; and the reviewers it will request or cancel before it mutates review requests. Unmatched files remain visible in the log. The pull-request author, approved owners, and users who remain requested are omitted from new requests.
+
+The policy test measures non-test tracked lines under matched directories and requires `@turtle1999` to own no more than one third of that eligible owned codebase.

+
+## Review exclusions
+
+Review routing excludes the repository's unit, end-to-end, expected-output, snapshot, benchmark, performance, stress, corpus, native, and Python test conventions. This includes `test`, `tests`, `__tests__`, `__snapshots__`, `benches`, and `stress-tests` directories; the top-level `benchmarks` and `snapshots` trees; `packages/test-support`; `scripts/fixtures` and `scripts/snapshots`; recognized test filename suffixes; and Python `test_*.py` or `*_test.py` files.
+
+Test infrastructure that can alter how evidence is produced remains reviewable, including `vitest*.config.ts` and gate implementations under `scripts`. A production file named `test.ts`, `spec.ts`, or `snapshot.ts` is not excluded solely by that name.
+
+Files ending in `.md` or `.yaml`, with case-insensitive extension matching, are documentation and never contribute owners. A `.yml` file remains reviewable unless another exclusion applies.
+
+For a modified file with a supported source extension, the scanner compares the pre-change and post-change text after removing parsed comments. It excludes the file only when GitHub supplies a patch whose counted additions and deletions prove that the patch is complete and the remaining code is identical. The parser recognizes C-style line and block comments, hash comments, SQL comments, CSS block comments, and HTML comments for their declared extensions. Renames, unsupported languages, missing or partial patches, and uncertain comment forms remain reviewable.
+
+<a id="security"></a>
+
+## Security
+
+The write-capable `pull_request_target` job checks out only the repository default branch. It does not check out or execute pull-request code and does not use repository secrets. Pull-request filenames are treated as API data and escaped in logs.
+
+Ownership changes take effect only after they merge into the default branch. This prevents an untrusted pull request from changing the routing program or its owner assignments for its own run.
+
+<a id="verification"></a>
+
+## Verification
+
+Run `pnpm run test:request-review` for ownership parsing, file classification, complete-patch checks, comment parsing, changed-LOC ranking, pagination, approval-state reduction, logging order, non-draft reconciliation, draft cancellation, reviewer provenance, reviewer filtering, and API behavior. [Workflow tests](../../scripts/ci-workflow.spec.ts) pin the trusted checkout, permissions, events, and command. The repository gate graph runs both checks in CI.

+The [review-routing decision](../../.agents/notes/implemented/process/2026-09-08-trusted-changed-file-review-routing.md) records the security model, test exclusions, and alternatives.

 ## Summary

-`dsh-acp` lets trusted programs drive persistent DeepSeek Harness agents over the standard [Agent Client Protocol](https://agentclientprotocol.com): create or resume sessions, list resumable sessions, attach standard MCP servers, select a model and reasoning effort, prompt or cancel work, receive semantic execution updates, and close one session without affecting others. It is built for automation — out-of-process subagents, test runners, and scripted controllers — rather than the DSH user interface: it emits standard ACP messages, thoughts, generic tool lifecycle, configuration, and context usage, never private DSH presentation data or methods. Session persistence enables list, resume, and close across process restarts, while deletion, fork, transcript replay, additional directories, and interactive UI surfaces remain unsupported. The repository's own ACP client is `dsh-subagent-acp`, and `pnpm dsh --profile acp` starts a ready-to-use server. Setup and usage come first; the implementation details live in a collapsible developer section below.
+`dsh-acp` lets trusted programs automate persistent DeepSeek Harness agents through the standard [Agent Client Protocol](https://agentclientprotocol.com): create or resume sessions, select a model and reasoning effort, attach MCP servers, submit or cancel work, receive semantic updates, and close sessions independently. Choose it for out-of-process subagents, test runners, and scripted controllers; it intentionally omits DSH-specific presentation data and interactive UI features. Persistence supports listing, resuming, and closing sessions across process restarts, but deletion, forks, transcript replay, and additional directories are unsupported. Run `pnpm dsh --profile acp` to start the server; use `dsh-subagent-acp` as the repository client.

 ## 概述

-`dsh-acp` 让受信程序可以通过标准 [Agent Client Protocol（ACP）](https://agentclientprotocol.com) 驱动持久 DeepSeek Harness agent：创建或恢复会话、列出可恢复会话、挂载标准 MCP 服务器、选择模型与推理强度、发送或取消工作、接收语义执行更新，并关闭一个会话而不影响其他会话。它是为自动化而生的——进程外 subagent、测试运行器与脚本化控制器——而不是 DSH 用户界面：它发送标准 ACP 消息、thought、通用工具生命周期、配置与上下文用量，绝不发送 DSH 私有呈现数据或方法。会话持久化支持跨进程重启的列出、恢复与关闭，而删除、fork、转录回放、附加目录与交互式 UI 界面仍不支持。仓库自带的 ACP 客户端是 `dsh-subagent-acp`，`pnpm dsh --profile acp` 会启动一个开箱即用的服务器。设置与用法在前；实现细节放在下方可折叠的开发者章节中。

 The listener signature is not restated here. Each allowlisted event's Cordis `Events` declaration lives in its owner package's client-safe `./types` export, and both faces of this package pull those declarations in. The Host face additionally asserts every entry against `TypertForwardableEventEntry`: an `emit` entry must be a declared one-way event, while a `waterfall` entry must be a declared Agent-scoped waterfall whose final parameter is its same-result `next()` callback.

-The Host entry registers an independent allowlist listener set and queue for each Client stream. It rejects non-JSON ordinary-event arguments before enqueueing. For a waterfall, it projects only the top-level Agent identity and JSON request fields; a Client result must also be lossless JSON, while `next()` delegates to the following Host listener. The source attaches all listeners synchronously before `ctx.typertGateway.registerRemoteEvents()` exposes Gateway's internal `$events` logical stream, so its first `ready` item proves that incremental delivery is active and carries the Host home for Client path display.

 The Session object also carries local submission echoes: `session.beginSubmission` inserts one into `SessionSnapshot.pendingSubmissions` synchronously, before the caller serializes and prompts, so a conversation UI can show the message on the submit click's own frame. The echo stores ordered image previews and durable file references. Session derives its `transcript`, `queued`, or `steering` placement from the current running state and requested delivery mode, then retains that placement while serialization is in flight. The prompt's `requestId` is the correlation identity: the Host echoes it as the durable user source's `rpcId`, and queue occurrences project it as `SessionQueuedItem.rpcId`. An echo retires one animation frame after its durable event or queue occurrence is observed, immediately when its identified prompt fails or is abandoned, and as failed on disposal. Each retirement fires `onRetire` exactly once; an observed retirement includes the ordered durable attachment references so the composer can release successful cards while preserving failed drafts. Echoes are Client memory only; reload and reconnect rebuild the conversation from durable events alone.

+## Session media references
+
+`SessionMediaReferences` mounts `GET|HEAD /api/file?path=<absolute path>` on the authenticated `connection.fetch` channel when `connection`, `fs`, and `attachments` are composed. It reads ordinary files through `ctx.fs`, including temporary paths outside registered workspaces and files in remote providers. Neither directory containment nor MIME categories restrict access; `mime-types` supplies the response type, with `application/octet-stream` for unknown extensions. GET reuses `readBytes` for preflight and ongoing byte limits; HEAD reads metadata only. All files use `ctx.attachments.imageLimits.maxImageBytes` (normally 20 MiB); exceeding this limit returns 413. Responses contain the complete file, ignore Range, and carry `private, no-store`, `nosniff`, and a sandbox CSP so directly opened HTML/SVG cannot execute with the API origin. The Client rewrite lives in `ui-chat` (`AssistantMarkdown`); audio/video responses are available, while Markdown audio/video player nodes remain separate work.

 Session 对象还承载本地提交回显：`session.beginSubmission` 在调用方序列化与 prompt 之前，同步把一条回显写入 `SessionSnapshot.pendingSubmissions`，会话 UI 因此能在点击提交的当帧显示消息。回显按顺序存放图片预览与持久文件引用。Session 根据当前运行状态与请求的投递模式推导其 `transcript`、`queued` 或 `steering` 位置，并在序列化期间保留该位置。prompt 的 `requestId` 是关联标识：Host 把它回显为 durable user source 的 `rpcId`，queue occurrence 也把它投影为 `SessionQueuedItem.rpcId`。回显在观察到其 durable event 或 queue occurrence 后延迟一个动画帧退休，带标识的 prompt 失败或被放弃时立即退休，销毁时按 failed 退休。每次退休恰好触发一次 `onRetire`；observed 退休还会携带有序的持久附件引用，让 composer 释放成功卡片并保留失败草稿。回显只存在于 Client 内存；刷新与重连只从 durable event 重建会话。

+## 会话媒体引用

+当 `connection`、`fs` 与 `attachments` 均被组合时，`SessionMediaReferences` 在鉴权 `connection.fetch` 通道上挂载 `GET|HEAD /api/file?path=<绝对路径>`。它通过 `ctx.fs` 读取普通文件，包括已注册工作区之外的临时路径与远程提供方中的文件。目录包含关系与 MIME 类别均不限制访问；`mime-types` 提供响应类型，未知扩展名使用 `application/octet-stream`。GET 复用 `readBytes` 执行读取前及读取中的字节限制；HEAD 只读取元数据。所有文件均使用 `ctx.attachments.imageLimits.maxImageBytes`（通常为 20 MiB）；超过此上限返回 413。响应包含完整文件，忽略 Range，并携带 `private, no-store`、`nosniff` 与 sandbox CSP，使直接打开的 HTML/SVG 无法以 API 源身份执行脚本。客户端重写位于 `ui-chat`（`AssistantMarkdown`）；音视频文件响应已可用，Markdown 音视频播放器节点仍是独立工作。
