ci: pick the webserver bind address from the installed schema

The 0.2.1-alpha.2 fix rendered `host` onto the container's own address unconditionally. Every earlier release still validates it against the union of the two literals 127.0.0.1 and 0.0.0.0, so those images now die in the boot smoke test with @deepseek-ai/dsh-host-webserver: ValidationError: invalid config: - $.host expected "127.0.0.1" | "0.0.0.0" but got "172.17.0.22" (at host) and their refresh rebuilds -- which the recipe-hash change re-queued anyway -- can no longer succeed. Probe the installed webserver schema instead: where it rejects the unspecified address render the container's own IPv4, otherwise keep 0.0.0.0 so older versions build exactly as they did before. The probe is overridable through DSH_INSTALL_ROOT so both branches are testable.
Bind the web UI to the container's own address: dsh 0.2.1+ rejects 0.0.0.0

-# Agent Notes
-
-English | [中文](README.zh.md)
-
-One kind of design doc lives here. An **Agent Note** records a decision or proposal that affects this codebase — the *why* and *what we gave up*, the parts code and docs can't carry. This file defines where Agent Notes live, when to write one, and [the in-file format](#the-file-format).
-
-## Layout and naming
-
-Every Agent Note has two axes, both encoded in its **path** — `{lifecycle}/{class}/yyyy-mm-dd-topic-title.md`:
-
- **Lifecycle** (the top-level folder) is the Agent Note's status, and an Agent Note moves between folders as that status changes:
-  - **`proposed/`** — proposals reviewed before implementation; not yet built (or only partly).
-  - **`implemented/`** — the decision shipped. The file records what was decided and what was rejected, and is **kept current with what actually shipped**: when the code later moves a file, renames a package, or changes a key/default, the Agent Note is updated in the same change to match (facts only — paths, names, structure — not the decision itself). See [implemented/AGENTS.md](implemented/AGENTS.md).
-  - **`rejected/`** — the proposal was considered and declined. Keep it only while its rationale prevents a tempting, meaningful mistake; otherwise delete the complete triplet.
- **Class** (the nested folder) is the *kind* of decision — see [Classification](#classification) below.
-
-The date in the filename is when the topic was **first proposed** (per git history). Cross-references between Agent Notes use relative markdown links (`[topic](../../implemented/architecture/2026-…-….md)`) — never bare prose or numbers — so they are mechanically checkable and survive moves between folders.
-
-The active lifecycle tree is the working inventory: browse its lifecycle/class folders or search the repository. Do not add a centralized `INDEX.md`; the [no-index Agent Note](implemented/process/2026-07-19-remove-generated-agent-note-index.md) owns the rationale. Low-future-value implemented records move to the separate frozen [`archived/`](archived/AGENTS.md) tree described below.
-
-## Classification
-
-Each Agent Note belongs to one path-encoded class from the closed set in `scripts/agent-note-tree.ts`; the classification gate rejects other folders. Adding a class requires updating the canonical set and this section. See the [classification Agent Note](implemented/process/2026-06-20-agent-note-classification.md).
-
-| Class | What it covers |
-|---|---|
-| `feature` | A new user- or model-facing capability. |
-| `bug-fix` | Corrects a defect or closes a gap a postmortem surfaced. |
-| `simplification` | Removes code, behavior, or surface area without adding a capability. |
-| `architecture` | A structural decision about the **shipped source** — how packages relate, what the runtime vocabulary is. |
-| `process` | Tooling, policy, or workflow **around** the code — gates, the package manager, vendoring — not runtime behavior. |
-| `testing` | Test infrastructure and strategy. |
-
-The `architecture` / `process` line: **architecture** is about the source we ship; **process** is the surrounding tooling and workflow. (`refactor` is deliberately absent — it overlaps `simplification`, whose discriminator, "does observable behavior change?", already covers it.)
-
-## Archiving and deletion
-
-Archive an implemented Agent Note when the shipped decision is complete and its rationale is unlikely to guide future work. Keep it active when its alternatives, ownership boundary, negative guarantee, durable or wire semantics, security rule, or reintroduction condition remains useful. Never archive a proposed note: reject an obsolete proposal. Keep a rejected note only while it prevents a plausible mistake; otherwise delete its English, Chinese, and sidecar files together. Use the calibrated [`dsh-archive-agent-notes`](../skills/dsh-archive-agent-notes/SKILL.md) workflow rather than word count, age, or a target quota.
-
-The archive is path-encoded as `archived/{class}/yyyy-mm-dd-topic-title.md`; `implemented` is deliberately absent because only implemented notes can enter it. An archival change moves the complete English/Chinese/sidecar triplet, retains `Status: implemented`, inserts the same `Archived: YYYY-MM-DD` line immediately below that status in both language files, re-records the sidecar, and repairs or deletes inbound links. These are the only permitted content changes during archival.
-
-Once sealed, every archived triplet is permanently frozen. Do not edit, translate, reformat, update, move, or delete it, and do not treat it as authority for current behavior. Documentation gates skip archived sources, including their outbound links; active prose may still link into an archived note when it intentionally cites history. [`verify-archived-agent-notes`](../../scripts/verify-archived-agent-notes.ts) enforces the closed class tree, complete triplets, archive metadata, sidecar hashes, and the append-only frozen-content manifest. The [archive-policy Agent Note](implemented/process/2026-07-26-frozen-agent-note-archive.md) owns the rationale.
-
-## When to write one
-
-Every non-trivial change MUST add or update at least one Agent Note in the same PR. A change is non-trivial when it alters behavior, architecture, a contract shared across files or packages, process or tooling, testing strategy, an on-disk, wire, or configuration format, or another decision a maintainer may reasonably revisit. A proposal for substantial future work starts in `proposed/`; a decision already made starts in `implemented/`. Pick the class folder that matches the decision (see [Classification](#classification)).
-
-Updating the Agent Note that already owns the decision satisfies the rule; do not create a duplicate. Only a purely mechanical or local edit with no change to behavior, contracts, structure, process, or rationale is exempt. An Agent Note is never edited into a *different decision*: supersede it with a new one, and keep both notes cross-linked unless the old note is later fully consolidated under the rule below. Editing an `implemented/` Agent Note to track where its existing decision lives is required, not forbidden; see [implemented/AGENTS.md](implemented/AGENTS.md).
-
-An implemented Agent Note that is fully superseded may be consolidated into the current owning note and deleted. Before deletion, the owner must preserve every unique rationale, alternative, consequence, required verification, and named coverage gap; repair every inbound link; and delete the Chinese counterpart and consistency record in the same change. Partial supersession does not qualify: keep both notes cross-linked and update every fact that remains current. Consolidation must not rewrite the old file into its opposite or rely on git history as the only copy of rationale.
-
-A feature-addition note may be consolidated into the later removal note only when the feature is absent from production code, configuration, schemas, durable or wire formats, migration, and compatibility behavior; no current documentation presents it as available; and no test exercises it as supported behavior. Removal rationale and tests that verify absence may remain. The removal owner preserves the original motivation, why it no longer justified the feature, alternatives to full removal, the capability given up, conditions for reintroduction, and verification of complete absence. Obsolete implementation inventories and tests that only verified the deleted behavior are not current verification evidence. Removing one transport, default, implementation, or presentation is partial supersession, as is any surviving durable data or compatibility handling.
-
-## The file format
-
-Every active Agent Note follows one in-file format, enforced by `pnpm run verify-agent-note-format` ([scripts/verify-agent-note-format.ts](../../scripts/verify-agent-note-format.ts), part of `doc-sync`); the rationale for the format — and the alternatives it rejected — is [the uniform-format Agent Note](implemented/process/2026-07-05-uniform-agent-note-format.md). Archived notes retain the format they had when sealed plus the archive-date line above.
-
-### The header block
-
-The first three lines of every Agent Note are exactly:
-
-```markdown
-# Agent Note: <title>
-
-Status: <status>
-```
-
-followed by a blank line. The `Status:` value is one of three forms, and must agree with the lifecycle folder the file sits in — the gate cross-checks them:
-
- `Status: proposed`
- `Status: implemented`
- `Status: rejected — <why, in one line>`
-
-The status carries no dates and no parentheticals: the filename holds the first-proposed date, git holds everything else, and an "accepted in amended form" note is body content (state the amendment where the decision is stated). The rejection reason is the one status with content, because a rejected Agent Note's verdict is the fact readers come for.
-
-### The body skeleton
-
-Every Agent Note opens its body with `## Problem` — the motivation, written to stand without the solution. What follows depends on the lifecycle; recurring sections use these canonical names and nothing else, while genuinely bespoke technical sections (package topology, wire contracts, schemas) remain free-form between the required ones.
-
-#### `proposed/`
-
-```markdown
-## Problem
-## Proposal
-…bespoke sections…
-## Alternatives considered
-## Acceptance criteria
-## Risks
-```
-
-`## Proposal` is the intended change and may legitimately speak in the future tense — plans, migration steps, and open questions belong here while the work is unbuilt. `## Acceptance criteria` says what observable state means done. `## Risks` covers both what could go wrong and what the change knowingly gives up.
-
-#### `implemented/`
-
-```markdown
-## Problem
-## Decision
-…bespoke sections…
-## Alternatives considered
-## Consequences
-```
-
-`## Decision` describes shipped reality in the present tense, and the whole file is kept current with it per [implemented/AGENTS.md](implemented/AGENTS.md). `## Consequences` records what the trade-off cost **and** bought. Proposal-era headings are spec-speak here and the gate rejects them: `## Proposal`, `## Plan`, `## Migration plan`, and `## Acceptance criteria` may not appear in an implemented Agent Note (the [slop checklist](../../docs/AGENTS.md) names why). A `## Testing`, `## Deferred`, or `## Related` section is fine where it states present-tense fact.
-
-#### `rejected/`
-
-A rejected Agent Note is the proposal, frozen: it keeps whatever proposal-time sections it had (including `## Acceptance criteria` or `## Plan`), and the verdict lives on the `Status:` line. Only the header block, the `## Problem` opener, a `## Proposal` section, and the Alternatives-considered mandate below apply.
-
-### Alternatives considered — mandatory
-
-Every Agent Note carries an `## Alternatives considered` section: each genuine alternative and why it lost, one bold-led paragraph per alternative or a `### Why not <X>?` subsection per contested one. A decision recorded without what it beat invites re-litigation — the failure Agent Notes exist to prevent.
-
-Alternatives are recorded, never invented. An Agent Note dated before 2026-07-05 whose alternatives are not reconstructible from the record carries this exact comment in place of the section, which the gate accepts for pre-format files only:
-
-```markdown
-<!-- agent-note-format: alternatives-not-recorded (pre-format Agent Note) -->
-```
-
-### Moving between lifecycles
-
-Moving a file between lifecycle folders means updating the `Status:` line and re-satisfying that folder's skeleton in the same change — the gate fails the move otherwise. Concretely, `proposed/` → `implemented/` rewrites `## Proposal` into a present-tense `## Decision`, folds `## Acceptance criteria` and `## Risks` into `## Consequences` (or a present-tense `## Testing`/`## Verification` section for what now pins the behavior), and drops plans in favor of what shipped — the rewrite [implemented/AGENTS.md](implemented/AGENTS.md) requires, made mechanical. `proposed/` → `rejected/` only adds the reason to the `Status:` line and freezes the file.
-
-### Chinese counterparts
-
-A `.zh.md` counterpart mirrors its English sibling's structure section-for-section under the [i18n contract](../../docs/i18n/README.md); the machine-checked header tokens (`# Agent Note: ` and the `Status:` line) stay in English verbatim. The format gate skips `.zh.md` files — the pairing gate checks their consistency.

-
-这里存放一类设计文档。**Agent Note** 记录影响本代码库的决策或提案：代码和文档无法承载的*为什么*以及*放弃了什么*。本文件规定 Agent Note 存放在哪里、何时需要写一份，以及[文件内格式](#the-file-format)。
-
-## 布局与命名
-
-每份 Agent Note 有两个维度，都编码在其**路径**中：`{lifecycle}/{class}/yyyy-mm-dd-topic-title.md`。
-
- **生命周期**（顶层文件夹）是 Agent Note 的状态，Agent Note 随状态变化在文件夹之间移动：
-  - **`proposed/`**：实施前评审的提案；尚未构建（或仅部分构建）。
-  - **`implemented/`**：决策已交付。文件记录做了什么决定、否决了什么，并**与实际交付的内容保持同步**：当代码后续移动文件、重命名包或更改键名/默认值时，Agent Note 在同一个变更中同步更新（仅限事实——路径、名称、结构——而非决策本身）。见 [implemented/AGENTS.md](implemented/AGENTS.md)。
-  - **`rejected/`**：提案经过讨论后被否决。仅当其决策依据仍能避免一种诱人且影响重大的错误时保留；否则删除完整的英文、中文和伴随记录三文件组。
- **类别**（嵌套文件夹）是决策的*种类*——见下方[分类](#classification)。
-
-文件名中的日期是该主题**首次提出**的时间（以 git 历史为准）。Agent Note 之间的交叉引用使用相对 Markdown 链接（`[topic](../../implemented/architecture/2026-…-….md)`），从不使用纯文字或编号，这样既可机械检查，也能在文件夹间移动时保持有效。
-
-活跃生命周期目录树就是工作清单：浏览其生命周期/类别文件夹，或搜索仓库即可。请勿添加集中式 `INDEX.md`；设计理由见[不设索引的 Agent Note](implemented/process/2026-07-19-remove-generated-agent-note-index.zh.md)。未来指导价值较低的已实施记录会移至下文所述、单独冻结的 [`archived/`](archived/AGENTS.md) 目录树。
-
-<a id="classification"></a>
-
-## 分类
-
-每份 Agent Note 属于 `scripts/agent-note-tree.ts` 中封闭集合里的一个路径编码类别；分类门禁拒绝其他文件夹。新增类别需要同时更新规范集合与本节。见[分类 Agent Note](implemented/process/2026-06-20-agent-note-classification.zh.md)。
-
-| 类别 | 覆盖范围 |
-|---|---|
-| `feature` | 面向用户或模型的新能力。 |
-| `bug-fix` | 修正缺陷或弥补事故复盘（postmortem）发现的缺口。 |
-| `simplification` | 在不增加能力的前提下移除代码、行为或对外范围。 |
-| `architecture` | 关于**交付源码**的结构性决策：包之间的关系、运行时词汇。 |
-| `process` | 代码**周边**的工具、策略或工作流——门禁、包管理器、vendor 化——不涉及运行时行为。 |
-| `testing` | 测试基础设施与策略。 |
-
-`architecture` 与 `process` 的界线：**architecture** 关乎我们交付的源码；**process** 关乎围绕源码的工具与工作流。（`refactor` 被有意排除：它与 `simplification` 重叠，而后者的判别标准「可观察行为是否改变」已经覆盖了它。）
-
-## 归档与删除
-
-当一份 implemented Agent Note 记录的交付决策已经完整落地，且其决策依据不太可能再指导未来工作时，将其归档。如果其中的备选方案、归属边界、否定性保证、持久化语义或协议语义、安全规则，或者重新引入条件仍有价值，则继续作为活跃记录保留。绝不归档 proposed Agent Note：过时的提案应转为 rejected。仅当 rejected Agent Note 仍能避免一种可能发生的错误时保留；否则一并删除其英文、中文和伴随记录文件。请使用经过校准的 [`dsh-archive-agent-notes`](../skills/dsh-archive-agent-notes/SKILL.md) 工作流，不要根据字数、存续时间或目标配额来判断。
-
-归档路径编码为 `archived/{class}/yyyy-mm-dd-topic-title.md`；其中有意省略 `implemented`，因为只有 implemented Agent Note 可以进入归档。归档变更会移动完整的英文、中文和伴随记录三个文件，保留 `Status: implemented`，在两种语言的文件中紧接该状态行插入相同的 `Archived: YYYY-MM-DD` 行，重新记录伴随记录，并修复或删除入站链接。归档时只允许对内容做这些更改。
-
-封存后，每组归档文件都永久冻结。禁止编辑、翻译、重新格式化、更新、移动或删除，也不得将其视为当前行为的权威依据。文档门禁会跳过归档源文件，包括其中的出站链接；当活跃文档有意引用历史时，仍可链接到归档 Agent Note。[`verify-archived-agent-notes`](../../scripts/verify-archived-agent-notes.ts) 强制执行封闭的类别目录树、完整的三文件配对、归档元数据、伴随记录 hash，以及仅追加的冻结内容 manifest（元数据清单）。[归档政策 Agent Note](implemented/process/2026-07-26-frozen-agent-note-archive.zh.md) 记录了设计依据。
-
-<a id="when-to-write-one"></a>
-
-## 何时需要写一份
-
-每个非平凡变更都必须在同一 PR（Pull Request）中新增或更新至少一份 Agent Note。如果变更修改了行为、架构、跨文件或跨包约定、流程或工具、测试策略、磁盘存储格式、协议格式（wire format）或配置格式，或者维护者可能合理重新审视的其他决策，就属于非平凡变更。对未来重大工作的提案从 `proposed/` 开始；已经做出的决策从 `implemented/` 开始。选择与决策匹配的类别文件夹（见[分类](#classification)）。
-
-更新已经拥有该决策的 Agent Note 即可满足规则；不要创建重复记录。只有不涉及行为、约定、结构、流程或理由变化的纯机械性或局部编辑才可豁免。Agent Note 永远不会被编辑为一个*不同的决策*：用新 Agent Note 取代旧记录，并让两个记录保持互相链接，除非后续依据下方规则完全合并旧记录。编辑 `implemented/` Agent Note 以跟踪其现有决策的所在位置是必需的，而非禁止的；见 [implemented/AGENTS.md](implemented/AGENTS.md)。
-
-被完全取代的 implemented Agent Note 可以合并到当前持有该决策的记录中，并删除原文件。删除前，当前记录必须保存所有独有的决策依据、备选方案、影响、必需的验证和明确指出的覆盖缺口；修复所有入站链接；并在同一变更中删除中文对侧文件和一致性记录。仅部分被取代的记录不符合此条件：保留两个记录并让它们互相链接，同时更新所有仍然适用的事实。合并不得将旧文件改写成与其相反的决策，也不得让 git 历史成为决策依据的唯一副本。
-
-只有当一项功能已从生产代码、配置、schema、持久化格式或协议格式、迁移和兼容行为中完全消失，当前文档不再将其描述为可用，且没有测试把它作为受支持行为来执行时，新增该功能的 Agent Note 才可合并进后续的移除记录。移除决策的依据和验证该功能已不存在的测试可以保留。移除决策的持有记录必须保留最初动机、为什么该动机已不足以证明保留该功能的合理性、完全移除之外的备选方案、放弃的能力、重新引入的条件，以及证明已彻底移除的验证。过时的实现清单和只验证已删除行为的测试不属于当前验证证据。仅移除一种传输、默认值、实现或展示属于部分取代；仍有任何持久数据或兼容处理也同样如此。
-
-<a id="the-file-format"></a>
-
-## 文件格式
-
-每份活跃 Agent Note 遵循统一的文件内格式，由 `pnpm run verify-agent-note-format`（[scripts/verify-agent-note-format.ts](../../scripts/verify-agent-note-format.ts)，`doc-sync`（文档同步门禁）的一环）强制执行；该格式的设计动机及其否决的替代方案见[统一格式 Agent Note](implemented/process/2026-07-05-uniform-agent-note-format.zh.md)。归档记录保留封存时的格式，并增加上述归档日期行。
-
-### 头部块
-
-每份 Agent Note 的前三行严格为：
-
-```markdown
-# Agent Note: <title>
-
-Status: <status>
-```
-
-后跟一个空行。`Status:` 的值有三种形式，且必须与文件所在的生命周期文件夹一致——门禁会交叉检查：
-
- `Status: proposed`
- `Status: implemented`
- `Status: rejected — <why, in one line>`
-
-状态行不带日期、不带括号补充说明：文件名记录首次提出日期，git 记录其余一切；「以修订形式接受」之类的说明属于正文内容（在陈述决策的地方说明修订）。拒绝原因是唯一带内容的状态，因为读者查阅被否决的 Agent Note 时，结论正是他们要找的。
-
-### 正文骨架
-
-每份 Agent Note 的正文以 `## Problem` 开头：动机，写法上不依赖解决方案即可独立成文。后续内容取决于生命周期；固定章节使用以下规范名称且仅限这些名称，而真正独特的技术章节（包拓扑、协议约定、schema 等）在必需章节之间可自由组织。
-
-#### `proposed/`
-
-```markdown
-## Problem
-## Proposal
-…bespoke sections…
-## Alternatives considered
-## Acceptance criteria
-## Risks
-```
-
-`## Proposal` 描述拟议的变更，可以合理地使用将来时态——计划、迁移步骤和待解决问题在工作尚未完成时属于此处。`## Acceptance criteria` 说明什么可观察状态意味着完成。`## Risks` 涵盖可能出错的事项以及该变更有意放弃的东西。
-
-#### `implemented/`
-
-```markdown
-## Problem
-## Decision
-…bespoke sections…
-## Alternatives considered
-## Consequences
-```
-
-`## Decision` 以现在时态描述已交付的现实，整个文件按 [implemented/AGENTS.md](implemented/AGENTS.md) 的要求与之保持同步。`## Consequences` 记录权衡的代价**与**收益。提案阶段的标题在此属于规格用语，门禁会拒绝它们：`## Proposal`、`## Plan`、`## Migration plan` 和 `## Acceptance criteria` 不得出现在 implemented Agent Note 中（原因见 [slop 检查清单](../../docs/AGENTS.md)）。`## Testing`、`## Deferred` 或 `## Related` 章节在陈述现在时态的事实时是允许的。
-
-#### `rejected/`
-
-被否决的 Agent Note 是冻结的提案：保留提案时的所有章节（包括 `## Acceptance criteria` 或 `## Plan`），结论写在 `Status:` 行上。仅头部块、`## Problem` 开头、`## Proposal` 章节以及下方的「曾考虑的替代方案」强制要求适用。
-
-### 曾考虑的替代方案——必需
-
-每份 Agent Note 都必须包含 `## Alternatives considered` 章节：每个真实的替代方案及其落选原因，每个替代方案用一个加粗引导的段落，或对争议较大的替代方案用 `### Why not <X>?` 子节。记录决策时不记录它击败了什么，就是在邀请反复争论——这正是 Agent Note 旨在防止的问题。
-
-替代方案是记录下来的，不是凭空编造的。日期早于 2026-07-05 且替代方案无法从记录中重建的 Agent Note，用以下精确注释代替该章节，门禁仅对格式规范之前的文件接受此注释：
-
-```markdown
-<!-- agent-note-format: alternatives-not-recorded (pre-format Agent Note) -->
-```
-
-### 在生命周期之间移动
-
-将文件在生命周期文件夹之间移动意味着在同一个变更中更新 `Status:` 行并满足目标文件夹的骨架要求——否则门禁会失败。具体而言，`proposed/` → `implemented/` 将 `## Proposal` 改写为现在时态的 `## Decision`，将 `## Acceptance criteria` 和 `## Risks` 折入 `## Consequences`（或折入一个现在时态的 `## Testing`/`## Verification` 章节，用于描述现在锁定该行为的内容），并用实际交付的内容替换计划——也就是将 [implemented/AGENTS.md](implemented/AGENTS.md) 所要求的改写变成可机械检查的规则。`proposed/` → `rejected/` 仅在 `Status:` 行添加原因并冻结文件。
-
-### 中文对侧文件
-
-`.zh.md` 对侧文件按 [i18n 约定](../../docs/i18n/README.zh.md)逐章节与其英文对侧文件保持相同结构；机器检查的头部标记（`# Agent Note: ` 和 `Status:` 行）保持英文原样不翻译。格式门禁跳过 `.zh.md` 文件；配对门禁检查它们的一致性。

-# Agent Note: Custom typed tool-schema DSL instead of schemastery
-
-Status: implemented
-Archived: 2026-07-26
-
-English | [中文](2026-06-11-custom-schema-dsl.zh.md)
-
-## Problem
-
-Tool parameters must reach the model as standard JSON Schema while giving tool authors typed `execute(args)` without casts. Schemastery already serves plugin config, but the tool-author API needs per-property `required: true` booleans rather than JSON Schema's separate `required` array.
-
-## Decision
-
-This decision is superseded by the [unified JSON-value schema DSL](2026-07-20-unified-json-value-schema-dsl.md), which retains the small authoring surface while making parameters and typed values share one vocabulary. `ParameterSchemaSpec` keeps per-property `required: true`; `InferArgs<S>` maps required keys to non-optional properties; `parameterSchemaSpecToJsonSchema()` compiles the implicit open object root; and `defineTool()` ties inference, compilation, and validation together. Raw JSON-Schema `ToolDefinition`s remain accepted by `ToolRegistry.register()` for MCP and other external tools.
-
-## Alternatives considered

-**Schemastery** (already vendored, used for plugin Config) was evaluated and rejected for this use: it targets validation / transformation against StandardSchema, not JSON Schema *generation*, so it would add indirection without producing the wire format cleanly.
-
-## Consequences
-
- First-party tool authors get zero-cast typed args; the type gymnastics cost stays inside the core package (sanctioned by the AGENTS.md type-safety policy).
- The owning unified note defines the current nodes, literal constraints, unions, JSON-value boundary, and object-openness rules.
- The `InferArgs` mapping is regression-tested at the type level after an early optionality bug.

-# Agent Note: 使用自定义类型化工具 schema DSL 替代 schemastery

-[English](2026-06-11-custom-schema-dsl.md) | 中文
-
-## 问题
-
-工具参数必须以标准 JSON Schema 形式到达模型，同时让工具作者在 `execute(args)` 中获得类型化的参数而无需类型断言。Schemastery 已用于插件配置，但工具作者 API 需要逐属性的 `required: true` 布尔值，而非 JSON Schema 的独立 `required` 数组。
-
-## 决策
-
-该决策已由[统一 JSON 值 schema DSL](2026-07-20-unified-json-value-schema-dsl.md)取代；新设计保留小型编写接口，同时让参数与类型化值共享一套词汇。`ParameterSchemaSpec` 保留逐属性的 `required: true`；`InferArgs<S>` 将必需键映射为非可选属性；`parameterSchemaSpecToJsonSchema()` 编译隐式开放的对象根；`defineTool()` 则将类型推导、编译与校验串联起来。原始 JSON Schema 的 `ToolDefinition` 仍是 `ToolRegistry.register()` 接受的输入，供 MCP 和其他外部工具使用。
-
-## 曾考虑的替代方案
-
-**Schemastery**（已作为 vendor 引入，用于插件 Config）经评估后被否决：它面向的是基于 StandardSchema 的校验／转换，而非 JSON Schema *生成*，因此会增加间接层却无法干净地产出协议格式（wire format）。
-
-## 后果
-
- 第一方工具作者获得零类型断言的类型化参数；类型体操的成本留在核心包内部（符合 AGENTS.md 的类型安全策略）。
- 当前节点、字面量约束、联合类型、JSON 值边界与对象开放性规则均由上述统一说明定义。
- `InferArgs` 映射在类型层面有回归测试，源于早期一个可选性 bug。

-English | [中文](2026-06-11-tool-schemas-in-prompt-assembly.zh.md)
-
-## Problem
-
-On the wire, tool schemas travel in a dedicated `tools` field of the model request, not in prompt text. Architecturally, though, "what the model is told it can do" is one coherent concern: prompt sections and the tool list are assembled from the same plugin contributions and consumed at the same moment.
-
-## Decision
-
-`PromptAssembly { sections, tools }`: the system-prompt service collects ordered text sections AND tool schemas (the tool registry auto-contributes a provider). The loop consumes one assembly per step; adapters map `sections` to the provider's system slot and `tools` to the wire `tools` field. The `system-prompt/assemble` waterfall is therefore a single interception point for everything the model is told up front — tool filtering (ToolSearch / progressive disclosure) is an assembly rewrite, same as prompt edits.
-
-## Alternatives considered
-
-**The loop queries the tool registry separately from the prompt service** — splits one coherent concern across two seams, and every interception that wants to shape "what the model is told" (tool filtering, plan mode) would need two listeners on two surfaces instead of one assembly rewrite.
-
-## Consequences
-
- One waterfall governs the model's standing context; plugins like plan mode can swap prompt text and visible tools in one listener.
- The assembly interface is merge-extensible for future slots (no untyped `extras` bag — extension is declaration merging).
- Slight conceptual surprise (schemas in a "prompt" service) is documented here and in the package README.

-[English](2026-06-11-tool-schemas-in-prompt-assembly.md) | 中文
-
-## 问题
-
-在协议格式（wire format）层面，工具 schema 通过模型请求中专用的 `tools` 字段传输，而非嵌入提示词文本。然而从架构角度看，「模型被告知它能做什么」是一个统一的关注点：提示词段落与工具列表由相同的插件贡献组装，并在同一时刻被消费。
-
-## 决策
-
-`PromptAssembly { sections, tools }`：系统提示词服务同时收集有序的文本段落和工具 schema（工具注册表自动贡献一个提供方）。agent loop（智能体循环）每个步骤消费一份 assembly；适配器将 `sections` 映射到提供方的 system 槽位，将 `tools` 映射到协议格式的 `tools` 字段。因此 `system-prompt/assemble` waterfall（瀑布式事件）是模型预先获知的所有信息的唯一拦截点：工具过滤（ToolSearch / 渐进式披露）是一次 assembly 重写，与提示词编辑无异。
-
-## 曾考虑的替代方案
-
-**循环从工具注册表和提示词服务分别查询**：将一个统一的关注点拆到两个 seam 上；任何想影响「模型被告知什么」的拦截（工具过滤、plan 模式）都需要在两个接口上各挂一个监听器，而非一次 assembly 重写即可完成。
-
-## 后果
-
- 一条 waterfall 统管模型的常驻上下文；plan 模式等插件可以在一个监听器中同时替换提示词文本和可见工具。
- assembly 接口通过声明合并实现可扩展（没有无类型的 `extras` 包——扩展即声明合并），为未来的槽位预留空间。

-# Agent Note: Every session event is enclosed in a turn
-
-Status: implemented
-Archived: 2026-07-28
-
-English | [中文](2026-06-15-turn-enclosure-invariant.zh.md)
-
-## Problem
-
-A durable session-persistence backend (added in a companion change) uses the **turn** as its crash-recovery boundary: a crash can leave an unclosed final turn, which `load` closes with a synthetic `turn/end {kind:'interrupted'}` while preserving the turn's real events (see [session persistence](2026-06-14-session-persistence.md)). This recovery is only well-defined if nothing *legitimately* durable sits OUTSIDE a turn — between the last `turn/end` and the next `turn/start` — since such an event would be swept into the next turn's interrupted close.
-
-That assumption did not hold. Two paths recorded events outside any turn:
-
-1. **Queued user messages.** The loop drained queued messages and appended `user/message` *before* `turn/start` — so a turn's own prompt sat in the gap between the previous `turn/end` and the next `turn/start`.
-2. **Idle context injection.** `agent.inject()` appends a `context/message` directly. Its real production caller is `dsh-tool-bash`, which injects a background-task completion notice from `ctx.bash.onTaskDone` — a callback that fires whenever a background bash task finishes, frequently while the agent is **idle** (between turns).
-
-In case 2, if the injected `context/message` is the last event before a flush/dispose (no later turn appends a `turn/end`), `scanLog` treats it as crash debris and **drops it on resume** — the injected context is durably on disk but silently lost on reload. Case 1 was benign in isolation (a `user/message` is always followed by the turn it triggered) but made the "what may appear outside a turn" rule fuzzy.
-
-## Decision
-
-**Every session event lives inside a turn** — between a `turn/start` and its matching `turn/end`. Concretely:
-
- The loop appends queued `user/message` events **after** `turn/start` (inside the turn), not before it. `turn/end` is therefore owed the moment those messages are recorded, and the existing finalizer guarantees it.
- An `agent.inject()` made while the agent is **running** joins the already-open turn. While the current step executes assistant tool calls, accepted context waits in arrival order until that batch settles, then appends after every recorded result and before the turn closes even when execution is interrupted.
- An `agent.inject()` made while **idle** wraps its `context/message` in a one-shot turn: `turn/start{trigger:{kind:'injection'}}` → `context/message` → `turn/end{completed}`. A new `injection` variant joins the merge-extensible `TurnTriggerMap`.
- The loop derives the next turn number from the log each iteration (`lastTurnNumber(session) + 1`) instead of keeping a private counter, so an idle injection's one-shot turn cannot collide with the next real turn's number.
- The `dsh-session/invariant` companion registers the check with `ctx.invariants`: when selected, a `user/message` / `context/message` / `steering/message` appended while no turn is open throws an `InvariantError` attributed to `@deepseek-ai/dsh-session`.
-
-The serializability invariant is enforced at the same source boundary (`Session.append` throws on non-JSON-serializable data), so "what may enter the log" is now governed in one place rather than discovered downstream by whichever backend happens to be watching.
-
-## Alternatives considered
-
-**Relax the reader instead of constraining the producer** — let `scanLog` commit events that sit outside an open turn. Rejected: a single, checkable producer-side rule beats a more permissive boundary scan that has to reason about partial turns *and* loose between-turn events.
-
-## Consequences
-
-The turn is now the *single* durability/replay boundary, so [session persistence](2026-06-14-session-persistence.md)'s crash-recovery rule is complete, not merely sufficient: an interrupted final turn is closed (with a synthetic `turn/end {interrupted}`) and its real events preserved, with zero risk of conflating between-turn context into it, because there is no between-turn context. `scanLog` stays simple (one possibly-open final turn, never a loose between-turn event), and an idle background-task notice survives persist + resume.
-
-Costs: `agent.inject()` while idle now writes three log lines instead of one, and the derived history gains a turn that carries only injected context (no assistant output) — `deriveMessages()` already derives purely by event type, so this renders identically. The `injection` trigger is a new on-disk vocabulary value; like every `SessionEventMap`/`TurnTriggerMap` addition it is part of the frozen format. Event ordering within a turn changed (`turn/start` now precedes `user/message`), which is observable to anything that asserted the old order — the loop's own tests were the only such consumers.
-
-The rule is intentionally producer-enforced and dev-checked rather than reader-tolerated: a future backend (SQLite/WAL) inherits the same clean boundary for free, and a plugin that records an event outside a turn fails loudly in dev instead of silently losing data on the next reload.
-
-Failures detected during a turn are logged before `turn/end`. A later flush failure has no valid in-turn position, so it is reported through `agent/error` and logging rather than appended as a session event. This preserves a balanced replay log; durable operational diagnostics require a separate telemetry channel.

-# Agent Note: 每个会话事件都封闭在一个轮次内

-## 问题
-
-持久化的会话持久化后端（在配套变更中引入）以**轮次**作为崩溃恢复边界：崩溃可能留下一个未关闭的最终轮次，`load` 会用一个合成的 `turn/end {kind:'interrupted'}` 将其关闭，同时保留该轮次的真实事件（见[会话持久化](2026-06-14-session-persistence.md)）。这种恢复只有在没有任何*合法的*持久事件位于轮次之外（即上一个 `turn/end` 与下一个 `turn/start` 之间的间隙）时才是良定义的，否则这类事件会被卷入下一个轮次的中断关闭中。
-
-这一假设并不成立。有两条路径在任何轮次之外记录了事件：
-
-1. **排队的用户消息。** agent loop（智能体循环）排空排队消息并在 `turn/start` *之前*追加 `user/message`——于是一个轮次自身的提示词落在了前一个 `turn/end` 与下一个 `turn/start` 之间的间隙中。
-2. **空闲时的上下文注入。** `agent.inject()` 直接追加一条 `context/message`。它在生产环境中的真实调用方是 `dsh-tool-bash`，后者从 `ctx.bash.onTaskDone` 注入后台任务完成通知——该回调在后台 bash 任务完成时触发，而这经常发生在 agent **空闲**（轮次之间）时。
-
-在情况 2 中，如果注入的 `context/message` 是 flush/dispose 之前的最后一个事件（之后没有轮次追加 `turn/end`），`scanLog` 会将其视为崩溃残留并在**恢复时丢弃**——注入的上下文已持久写入磁盘，但重新加载后被静默丢失。情况 1 本身无害（`user/message` 之后总会跟着它触发的轮次），但使「什么可以出现在轮次之外」这条规则变得模糊。
-
-## 决策
-
-**每个会话事件都位于一个轮次内部**：在 `turn/start` 与其匹配的 `turn/end` 之间。具体而言：
-
- agent loop 在 `turn/start` **之后**（轮次内部）追加排队的 `user/message` 事件，而非之前。因此，一旦这些消息被记录，就欠下一个 `turn/end`，既有的 finalizer 保证它被写入。
- agent **运行中**调用 `agent.inject()` 时，它会加入已打开的轮次。当前步骤执行 assistant 工具调用期间，已接受的上下文按到达顺序等待该批次结算，随后在每个已记录结果之后追加；即使执行中断，也会在轮次关闭前写入。
- agent **空闲时**调用 `agent.inject()`，则将 `context/message` 包裹在一个一次性轮次中：`turn/start{trigger:{kind:'injection'}}` → `context/message` → `turn/end{completed}`。一个新的 `injection` 变体加入可合并扩展的 `TurnTriggerMap`。
- agent loop 每次迭代从日志推导下一个轮次编号（`lastTurnNumber(session) + 1`），而不是维护一个私有计数器，这样空闲注入的一次性轮次不会与下一个真实轮次的编号冲突。
- `dsh-session/invariant` companion 将该检查注册到 `ctx.invariants`：选中后，在没有打开轮次的情况下追加 `user/message` / `context/message` / `steering/message` 会抛出归因于 `@deepseek-ai/dsh-session` 的 `InvariantError`。
-
-可序列化性不变式在同一源码边界处强制执行（`Session.append` 对不可 JSON 序列化的数据抛出异常），因此「什么可以进入日志」现在由一个位置统一管控，而非由下游碰巧在监听的某个后端各自发现。
-
-## 曾考虑的替代方案
-
-**放宽读取端而非约束生产端**——让 `scanLog` 提交位于已打开轮次之外的事件。否决：一条单一、可检查的生产端规则优于一个更宽松的边界扫描（后者需要同时推理部分轮次*和*轮次间的散落事件）。
-
-## 后果
-
-轮次现在是*唯一的*持久性/回放边界，因此[会话持久化](2026-06-14-session-persistence.md)的崩溃恢复规则是完备的，而不仅仅是充分的：被中断的最终轮次被关闭（用合成的 `turn/end {interrupted}`），其真实事件得以保留，且零风险将轮次间上下文混入其中，因为不存在轮次间上下文。`scanLog` 保持简洁（最多一个可能未关闭的最终轮次，绝无散落的轮次间事件），空闲时的后台任务通知在持久化 + 恢复后依然存活。
-
-代价：空闲时调用 `agent.inject()` 现在写入三行日志而非一行；派生的历史中多出一个仅包含注入上下文（无 assistant 输出）的轮次——`deriveMessages()` 已经纯粹按事件类型派生，因此渲染结果完全相同。`injection` 触发器是一个新的磁盘词汇值；与每次 `SessionEventMap`/`TurnTriggerMap` 的新增一样，它属于冻结格式的一部分。轮次内的事件顺序发生了变化（`turn/start` 现在先于 `user/message`），这对任何断言旧顺序的代码可观测——agent loop 自身的测试是唯一的此类消费方。
-
-该规则有意采用生产端强制、开发环境检查的方式，而非读取端容忍的方式：未来的后端（SQLite/WAL）无需额外工作即可继承同样干净的边界，而在轮次外记录事件的插件会在开发环境中大声失败，而非在下次重新加载时静默丢失数据。
-
-轮次内检测到的失败在 `turn/end` 之前记录。后续的 flush 失败没有有效的轮次内位置，因此通过 `agent/error` 和日志报告，而非作为会话事件追加。这保持了回放日志的平衡；持久化的运维诊断需要一个独立的遥测通道。

-## Problem
-
-An example folder is supposed to be *thin* — the variable wiring of a demo, not the demo's machinery. Before this change it was thick. Each example carried a hand-rolled `start.ts` boot bootstrap, an infra preamble (`timer`, and — for the stdio demos — `logger` + `hmr`), nested includes of three shared YAML fragments (`base.yml` / `base-core.yml` / `acp-agent/acp-tail.yml`), and per-example `agent-loop`/persistence/system-prompt config. The actual app — the spine of services every agent needs — was spread across the leaf and those includes.
-
-The leaf configs also owned coupled front doors. ACP requires stdout purity and creates agents through `session/new`; terminal and Headless apps pre-create `main` but have different process I/O contracts. Prose warnings were the only guard against combining these incorrectly, while three `start.ts` files duplicated the Loader bootstrap and lifecycle code.
-
-## Decision
-
-Each example is now **mostly an invocation of an app package**, splitting the wiring along the existing [interface / implementation / consumer seam](2026-06-13-capability-seams.md): the **app package owns the composition**, the leaf `cordis.yml` owns only the **swappable choices** (which LLM adapter, which bash executor, model, prompt, persistence root).
-
- **`@deepseek-ai/dsh-agent-spine-demo`** ([packages/examples/agent-spine-demo](../../../../packages/examples/agent-spine-demo)) composes the providerless, executor-less, UI-less spine and forwards the loop's agent-list config. Its dependency on the concrete loop is intentional because this package composes the spine rather than extending it; swapping the loop means supplying another bundle.
- **`@deepseek-ai/dsh-tui-demo`**, **`@deepseek-ai/dsh-cli-demo`**, and **`@deepseek-ai/dsh-acp-demo`** bake in their process roles. TUI includes the full-screen UI and a pre-created `main`; Headless includes the one-shot driver and a pre-created `main`; ACP includes the bridge and no pre-created agent. All three include JSONL persistence and omit stdout loggers.
- **`start.ts` is gone.** Each app package exposes a bin; the `demo:*` scripts invoke it. Loader boot, `.env` loading, and fail-loud guards live in the shared [`@deepseek-ai/dsh-app-boot`](../../../../packages/ui/app-boot) package (unit-tested under the per-file coverage gate — see [share the app bins' boot glue](../simplification/2026-07-04-share-app-bin-boot-glue.md)); the thin self-executing entries are driven by keyless Loader-path tests.
- **Each leaf `cordis.yml` collapses** to backends, optional product tools, and one app entry carrying the app config. TUI and Headless route model/session choices onto a pre-created agent; ACP routes the initial provider/model onto its bridge.
- **`base.yml`, `base-core.yml`, and `acp-agent/acp-tail.yml` are retired** — the spine they shared now lives in `dsh-agent-spine-demo`.
-
-`bash-local` and the LLM adapter stay **leaf choices**: the bundle ships `tool-bash` (the consumer schema), the leaf picks the executor implementation, so a sandboxed executor or replay adapter swaps in without touching the app.
-
-### Amendment on implementation: `hmr` stays a leaf entry
-
-The proposal listed `hmr` among the interactive app's baked-in front-door cluster. Validating against the code, baking `hmr` into the app package fights Cordis in two ways, so it ships as a **leaf `cordis.yml` entry** instead:
-
-1. `@cordisjs/plugin-hmr` is a Loader-only, subprocess-only dev plugin — it requires the live `loader` service and its internal module access, so it can only run in the real `demo:*`/bin subprocess, never in the in-process unit/coverage tier.
-2. The in-process test tier (vitest) cannot even *import* the vendored `hmr` module (its class-decorator `@Inject` form fails under Vite's transform), so a package whose `apply` statically imported it could never satisfy the per-file 100% coverage gate on its headline function.
-
-Crucially, `hmr` is not a stdout-purity footgun: a stray entry in the ACP config does not corrupt JSON-RPC frames. Every shipped app omits a stdout console logger; the app or protocol driver alone owns stdout.
-
-## Alternatives considered
-
-### Why not keep the wiring in shared YAML includes?
-
-The old `base*.yml`/`acp-tail.yml` includes already deduped the *config*, but a YAML include cannot **encapsulate** the front-door coupling — it can only describe it in a comment and trust every leaf to obey. It also cannot own a `bin`, so the boot glue stayed copied across three `start.ts` files. A package turns "the ACP app never logs to stdout" from a prose warning into a property of the artifact: there is no logger entry in the leaf to get wrong.
-
-## Verification
-
- Example directories contain only their config, README, and tests: `start.ts`, the infrastructure preamble, and the shared YAML includes are gone.
- `demo:tui`, `demo:headless`, and `demo:acp` invoke the app-package bins.
- Each new package has a README and per-file 100% coverage; each app package also has a keyless real-Loader-path bin smoke that catches export-shape failures described in [postmortem 0001](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md).
- The ACP replay suite boots through the app-package bin, so protocol wiring and assembled backend behavior cross the real Loader boundary.
-
-## Consequences
-
- **The bare-plugin-tree pedagogy.** The spine lives behind a bundle, so seeing the whole tree means opening `dsh-agent-spine-demo`. The app package's README carries that teaching weight.
- **A layer of indirection.** "What does this demo load?" becomes a package read, not a single YAML scan.
-
-## Related
-
- Supersedes [Make the shared example base providerless](../../rejected/architecture/2026-06-20-providerless-example-base.md): renaming `base.yml` to the providerless core is moot once the spine moves into `dsh-agent-spine-demo` and the `base*.yml` files are deleted.
- Builds on the [capability-seams](2026-06-13-capability-seams.md) interface/implementation/consumer split — backends and presentation stay leaf choices; the spine is the shared bundle.

-## 问题
-
-示例目录本应是*精简的*——只包含演示的可变接线，而非演示的基础设施。在此次变更之前，它是臃肿的。每个示例都携带一份手写的 `start.ts` 启动引导、一段基础设施前导（`timer`，以及 stdio 演示所需的 `logger` + `hmr`（热模块替换））、三个共享 YAML 片段的嵌套引用（`base.yml` / `base-core.yml` / `acp-agent/acp-tail.yml`），还有各示例自身的 `agent-loop`/持久化/系统提示词配置。真正的应用——每个 agent（智能体）都需要的服务主干——散落在叶子配置和那些 include 中。
-
-叶子配置还拥有耦合的前门。ACP（Agent Client Protocol）要求 stdout 纯净，并通过 `session/new` 创建 agent；终端应用和 Headless 应用则预创建 `main`，但进程 I/O 契约不同。防止错误组合的唯一屏障是文档中的文字警告，而三个 `start.ts` 文件重复着 Loader 引导和生命周期代码。
-
-## 决策
-
-每个示例现在**主要是对一个应用包（package）的调用**，沿着既有的[接口 / 实现 / 消费方 seam](2026-06-13-capability-seams.md) 拆分接线：**应用包拥有组合**，叶子 `cordis.yml` 只拥有**可替换的选择**（哪个 LLM（大语言模型）适配器、哪个 bash 执行器、模型、提示词、持久化根目录）。
-
- **`@deepseek-ai/dsh-agent-spine-demo`**（[packages/examples/agent-spine-demo](../../../../packages/examples/agent-spine-demo)）组合了不含提供方、不含执行器、不含 UI 的主干，并转发 agent loop（智能体循环）的 agent 列表配置。它对具体 loop 的依赖是有意为之，因为该包组合的是主干而非扩展主干；替换 loop 意味着提供另一个 bundle。
- **`@deepseek-ai/dsh-tui-demo`**、**`@deepseek-ai/dsh-cli-demo`** 和 **`@deepseek-ai/dsh-acp-demo`** 各自内置其进程角色。TUI 包含全屏 UI 和预创建的 `main`；Headless 包含 one-shot driver 和预创建的 `main`；ACP 包含 bridge 且不预创建 agent。三者都包含 JSONL 持久化，并省略 stdout logger。
- **`start.ts` 已移除。** 每个应用包都暴露一个 bin；`demo:*` 脚本调用它。Loader 引导、`.env` 加载和快速失败守卫位于共享的 [`@deepseek-ai/dsh-app-boot`](../../../../packages/ui/app-boot) 包（在逐文件覆盖率门禁下有单元测试——见[共享应用 bin 的启动胶水](../simplification/2026-07-04-share-app-bin-boot-glue.md)）；精简的自执行入口由 keyless 的 Loader 路径测试驱动。
- **每个叶子 `cordis.yml` 精简为**后端、可选产品工具，以及一个承载应用配置的 app 条目。TUI 和 Headless 把模型/会话选择路由到预创建的 agent；ACP 把初始提供方/模型路由到 bridge。
- **`base.yml`、`base-core.yml` 和 `acp-agent/acp-tail.yml` 已退役**——它们共享的主干现在位于 `dsh-agent-spine-demo` 中。
-
-`bash-local` 和 LLM 适配器仍然是**叶子选择**：bundle 提供 `tool-bash`（消费方 schema），叶子选择执行器实现，因此沙箱执行器或回放适配器无需触碰应用即可替换。

-提案最初将 `hmr` 列入交互式应用内置的前门集群。对照代码验证后发现，将 `hmr` 内置到应用包中会在两个方面与 Cordis 冲突，因此改为作为**叶子 `cordis.yml` 条目**交付：
-
-1. `@cordisjs/plugin-hmr` 是一个仅限 Loader、仅限子进程的开发插件——它需要活跃的 `loader` 服务及其内部模块访问权限，因此只能在真实的 `demo:*`/bin 子进程中运行，不能在进程内的单元/覆盖率测试层运行。
-2. 进程内测试层（vitest）甚至无法*导入* vendor 的 `hmr` 模块（其 class-decorator `@Inject` 形式在 Vite 的 transform 下会失败），因此一个 `apply` 静态导入了它的包永远无法满足其主函数的逐文件 100% 覆盖率门禁。
-
-关键在于，`hmr` 不是 stdout 纯净隐患：ACP 配置中误加该条目不会破坏 JSON-RPC 帧。所有已交付应用都省略 stdout 控制台 logger；stdout 只归应用或协议 driver 所有。
-
-## 曾考虑的替代方案
-
-### 为什么不继续用共享 YAML include 来管理接线？
-
-旧的 `base*.yml`/`acp-tail.yml` include 已经去重了*配置*，但 YAML include 无法**封装**前门耦合——它只能在注释中描述，并信任每个叶子遵守。它也无法拥有 `bin`，因此启动胶水一直在三个 `start.ts` 文件中重复。包将「ACP 应用绝不向 stdout 输出日志」从文字警告变成了产物的属性：叶子中不存在可以写错的 logger 条目。
-
-## 验证
-
- 示例目录只包含配置、README 和测试：`start.ts`、基础设施前导和共享 YAML include 已移除。
- `demo:tui`、`demo:headless` 和 `demo:acp` 调用应用包的 bin。
- 每个新包都有 README 和逐文件 100% 覆盖率；每个应用包还有一个 keyless 的真实 Loader 路径 bin 冒烟测试，用于捕获[事后分析 0001](../../../../docs/postmortem/0001-acp-default-export-drops-inject.md) 中描述的导出形状故障。
- ACP 回放套件通过应用包的 bin 启动，因此协议接线与组装后的后端行为都跨越真实的 Loader 边界。
-
-## 后果
-
- **裸插件树的教学性。** 主干现在隐藏在 bundle 之后，查看完整树意味着打开 `dsh-agent-spine-demo`。应用包的 README 承担了这份教学职责。
- **多了一层间接。**「这个演示加载了什么？」从扫描单个 YAML 变成了阅读一个包。
-
-## 相关
-
- 取代[使共享示例基础配置与提供方无关](../../rejected/architecture/2026-06-20-providerless-example-base.md)：一旦主干移入 `dsh-agent-spine-demo` 且 `base*.yml` 文件被删除，将 `base.yml` 重命名为无提供方核心便不再有意义。
- 基于[能力 seam](2026-06-13-capability-seams.md)的接口/实现/消费方拆分——后端和展示层保持为叶子选择；主干是共享 bundle。
- 与[将包重组为模块化层级结构](2026-06-20-package-hierarchy.md)互补：新的 app/core 包按该层级结构归入既有分组（`core` 放可复用的主干 bundle，`ui` 放应用特有的前门）。
- 后续的[冗余 agent 移除](../simplification/2026-07-20-remove-stdio-and-echo-agents.md)拥有最终的 TUI/Headless 拆分，并移除行式与仅 mock 的叶子。

-# Agent Note: Reorganize packages into a modular hierarchy
-
-Status: implemented
-Archived: 2026-07-27
-
-English | [中文](2026-06-20-package-hierarchy.zh.md)
-
-The [redundant-agent removal](../simplification/2026-07-20-remove-stdio-and-echo-agents.md) deletes the original `support/ui-stdio` surface instead of relocating it, and the [automation-only ACP decision](../simplification/2026-07-23-acp-automation-only-protocol.md) places ACP under `packages/acp/acp` instead of the human-UI group. The uniform depth-two hierarchy remains the decision owned here.
-
-## Problem
-
-`packages/` was flat: 18 packages all sat at `packages/<name>/`, so a package's location said nothing about whether it was core product API, a swappable capability seam, a provider adapter, a product integration, or example/test support. The package README carried a `FIXME(package-hierarchy)` and `scripts/publint-all.ts` a `TODO(package-inventory)` flagging exactly this. Core packages, provider integrations, capability seams, example UI support, and snapshot-only replay support all looked equally foundational.
-
-This was not just cosmetic. Because every top-level package looked like part of the same public surface, future removal was harder, and publish/lint/doc scripts had to encode intent through comments or hand-maintained static lists rather than reading it off the layout.
-
-## Decision
-
-Packages are grouped by modular role at a uniform `packages/<group>/<pkg>/` depth. Group directories are pure containers (no `package.json`); every package keeps its `@deepseek-ai/dsh-<pkg>` name — this is repo structure and maintenance policy, not package renaming.
-

-    invariants/
-    ui-stdio/
-    llm-replay/
-```
-
-### Placement decisions
-
- **Same-name nesting for capability families.** A family's interface package sits at `packages/<group>/<group>/` (`llm/llm`, `bash/bash`, `session-persistence/session-persistence`), with implementations and consumers as flat siblings. There is no extra `adapters/`/`impls/` sub-tier — every package is exactly depth 2, which keeps the workspace glob a clean `packages/*/*` and lets one `@deepseek-ai/dsh-*` tsconfig wildcard resolve every package (unique dir names make first-on-disk-wins unambiguous).
- **`session` stays in `core/`; persistence is its own family.** The session log is core product API. Its storage backends form a parallel capability family (`session-persistence/`) mirroring `llm/` and `bash/`, rather than nesting under `core/session/`.
- **`agent-loop` is in `core/`.** It is the one concrete implementation of the `agent` seam, but it ships as the harness's default product loop, so it lives with the core spine. Plugins still depend on the `agent` vocabulary, never on `agent-loop`, so the loop stays swappable.
- **Product automation and human UI are separate groups.** `acp` is a product transport under `acp/`, while commands, approvals, interaction, and presentation adapters live under `ui/`. Dev-only invariants and replay infrastructure remain under `support/`.
-
-### Deduplicating the package lists
-
-The package list had been enumerated in five places. The uniform depth-2 layout lets most of them be derived instead:
-
- `tsconfig.base.json` maps every package through a single `@deepseek-ai/dsh-*` `paths` wildcard listing one candidate per group, in place of per-package entries. The aggregate configs (`tsconfig.host.json`, `tsconfig.client.json`) reuse that source map and carry the explicit project references that keep package/vendor typecheck boundaries intact. (One subtlety this introduced: a path candidate contains `/*/`, which a naive regex comment-stripper mistakes for a block comment — `scripts/doc-typecheck.ts` reads the JSONC config through TypeScript's parser rather than stripping comments by hand for exactly this reason.)
- `scripts/publint-all.ts` derives its list by reading the hierarchy (`packages/<group>/<pkg>`), resolving the `TODO(package-inventory)`.
- The aggregates' project `references` stay explicit lists — TypeScript project references have no wildcard form. Generating these from a manifest is left to a follow-up (see [discover package inventories](../../proposed/process/2026-06-20-discover-package-inventory.md)).
-
-### Guardrails added
-
-Two doc-sync/hygiene gates keep the structure and its references honest, so the manual checks this restructure required do not have to be repeated by hand:
-
- `scripts/verify-package-paths.ts` flags a `packages/<path>` reference (in Markdown or a `.ts` comment/string) that does not resolve **and** names a real package in a segment — i.e. a stale path to a moved package. A path naming a package that exists nowhere (a forward-looking proposal) is left alone, so the gate applies uniformly across proposed/implemented/rejected.
- `scripts/check-workspace-constraints.ts` asserts the `packages/<group>/<pkg>` shape: group dirs carry no `package.json`, and no package sits flat at the root or nests deeper. Group names stay open — a new group may be added without editing the gate; only the depth-2 shape is fixed.
-
-## Alternatives considered
-
- **A third tier (`adapters/` / `impls/` under each family)** — rejected: uniform depth 2 keeps the workspace glob a clean `packages/*/*` and lets one `@deepseek-ai/dsh-*` tsconfig wildcard resolve every package.
- **Nesting persistence under `core/session/`** — rejected: the storage backends form a parallel capability family mirroring `llm/` and `bash/`, while the session log itself stays core product API.
- **`ui-stdio` under `ui/`** — rejected: it was example-coupled dev support, not a product surface.
-
-## Consequences
-
-The restructure churned imports, workspace globs, doc links, build references, and package paths in one coordinated move. That churn is acceptable pre-release (per the AGENTS.md foundation-over-blast-radius stance) because it stops the flat layout from fossilizing support packages as product contracts, and it is a one-time cost: the wildcard `paths`, the glob-derived publint list, and the shape gate mean a new package needs no further structural edits.

-[冗余 agent 移除](../simplification/2026-07-20-remove-stdio-and-echo-agents.md)直接删除最初的 `support/ui-stdio` 接口，而不是将其迁移；[仅面向自动化的 ACP 决策](../simplification/2026-07-23-acp-automation-only-protocol.md)把 ACP 放在 `packages/acp/acp` 下，而不是面向人类的 UI 组。这里拥有的决策仍是统一的二层目录深度。
-
-## 问题
-
-`packages/` 原先是扁平的：18 个包（package）全部位于 `packages/<name>/`，从路径上完全看不出一个包属于核心产品 API、可替换的能力 seam、提供方适配器、产品集成，还是示例/测试支撑。包的 README 带着 `FIXME(package-hierarchy)`，`scripts/publint-all.ts` 带着 `TODO(package-inventory)`，标记的正是这个问题。核心包、提供方集成、能力 seam、示例 UI 支撑和仅用于快照的回放支撑看起来同样基础。
-
-这不仅仅是外观问题。由于每个顶层包看起来都属于同一个公开接口，未来移除更加困难，而 publish/lint/doc 脚本不得不通过注释或手工维护的静态列表来编码意图，而不是从布局中直接读取。
-
-## 决策
-
-按模块角色将包分组，统一放在 `packages/<group>/<pkg>/` 深度。分组目录是纯容器（没有 `package.json`）；每个包保留其 `@deepseek-ai/dsh-<pkg>` 名称——这是仓库结构与维护策略的调整，不是包的重命名。

-```
-
-### 放置决策
-
- **能力族使用同名嵌套。** 一个族的接口包位于 `packages/<group>/<group>/`（`llm/llm`、`bash/bash`、`session-persistence/session-persistence`），实现和消费方作为扁平兄弟并列。不设额外的 `adapters/`/`impls/` 子层——每个包恰好在深度 2，这使 workspace glob 保持简洁的 `packages/*/*`，并让一条 `@deepseek-ai/dsh-*` tsconfig 通配符即可解析所有包（唯一的目录名使 first-on-disk-wins 无歧义）。
- **`session` 留在 `core/`；持久化独立成族。** 会话日志是核心产品 API。其存储后端构成一个平行的能力族（`session-persistence/`），与 `llm/` 和 `bash/` 对称，而非嵌套在 `core/session/` 下。
- **`agent-loop` 在 `core/` 中。** 它是 `agent` seam 唯一的具体实现，但作为 harness 的默认产品循环交付，因此与核心主干同处。插件仍然依赖 `agent` 的词汇，从不依赖 `agent-loop`，所以循环仍可替换。
- **产品自动化与面向人类的 UI 是两个独立分组。** `acp` 是位于 `acp/` 下的产品传输层，而命令、审批、交互和展示适配器位于 `ui/` 下。仅开发用的 invariants 与回放基础设施仍留在 `support/` 中。
-
-### 去重包列表
-
-包列表此前在五个地方重复枚举。统一的深度 2 布局使大部分可以被推导：
-
- `tsconfig.base.json` 通过一条 `@deepseek-ai/dsh-*` `paths` 通配符（每个分组列一个候选）映射所有包，取代了逐包条目。聚合配置（`tsconfig.host.json`、`tsconfig.client.json`）复用该源映射，并携带显式 project references 以保持包/vendor 类型检查边界完整。（这里引入了一个细节：路径候选中包含 `/*/`，朴素的正则注释剥离器会将其误认为块注释——`scripts/doc-typecheck.ts` 正是因此通过 TypeScript 解析器读取 JSONC 配置，而非手动剥离注释。）
- `scripts/publint-all.ts` 通过读取层级结构（`packages/<group>/<pkg>`）推导列表，解决了 `TODO(package-inventory)`。
- 聚合配置的 project `references` 仍为显式列表——TypeScript project references 没有通配符形式。从 manifest（元数据清单）生成这些引用留作后续工作（见[通过发现机制获取包清单](../../proposed/process/2026-06-20-discover-package-inventory.md)）。
-
-### 新增的护栏
-
-两道 doc-sync/hygiene 门禁确保结构及其引用保持正确，使本次重组所需的手动检查无需日后重复：
-
- `scripts/verify-package-paths.ts` 标记 Markdown 或 `.ts` 注释/字符串中的 `packages/<path>` 引用，如果该引用无法解析**且**某个路径段命名了一个真实存在的包，即指向已移动包的陈旧路径。如果路径命名的包在任何地方都不存在（前瞻性提案），则不予标记，因此该门禁在 proposed/implemented/rejected 中统一适用。
- `scripts/check-workspace-constraints.ts` 断言 `packages/<group>/<pkg>` 形状：分组目录不带 `package.json`，且没有包扁平地位于根层或嵌套更深。分组名称保持开放——添加新分组无需修改门禁；只有深度 2 的形状是固定的。
-
-## 曾考虑的替代方案
-
- **第三层（每个族下设 `adapters/`/`impls/`）**：否决。统一深度 2 使 workspace glob 保持简洁的 `packages/*/*`，并让一条 `@deepseek-ai/dsh-*` tsconfig 通配符即可解析所有包。
- **将持久化嵌套在 `core/session/` 下**：否决。存储后端构成一个平行的能力族，与 `llm/` 和 `bash/` 对称，而会话日志本身属于核心产品 API。
- **`ui-stdio` 放在 `ui/` 下**：否决。它曾是与示例耦合的开发支撑，不是产品接口。
-
-## 后果
-
-本次重组在一次协调的变更中搅动了 import、workspace glob、文档链接、构建引用和包路径。这种变动在发布前是可接受的（依据 AGENTS.md 中「基础优先于爆炸半径」的立场），因为它阻止了扁平布局将支撑包固化为产品契约，且这是一次性成本：通配符 `paths`、glob 推导的 publint 列表和形状门禁意味着新增一个包无需额外的结构性编辑。

-# Agent Note: Result-time applied-hunk diffs for file mutations

-Archived: 2026-07-27

-## Problem
-
-The [tagged render-intent union](2026-07-02-tool-render-intent-union.md) gives `dsh-tool-fs` write/edit a `card:'diff'` at call time, derived purely from the tool's args: write ⇒ `{oldText:null, newText:content}` (the whole new file), edit ⇒ `{oldText:old_string, newText:new_string}` (the bare replaced snippet). A UI can render that as an inline diff, but it is a **context-free** diff — the bare `old_string`→`new_string` with no surrounding lines, and a `replace_all` that touched five scattered sites still renders as one snippet pair.
-
-Driving `claude-agent-acp`'s own ACP bridge shows what a full editor diff looks like: after the mutation applies, it emits a SECOND `tool_call_update` whose diff is the **applied hunk with ±3 context lines** (and one hunk per changed site for `replace_all`), reconstructed from the tool's `structuredPatch`. That result-time hunk is what makes Zed show the change *in place* in the file rather than as a floating snippet. Our tools stopped at the call-time snippet; the completed result carried only the plain "updated successfully" text, no diff.
-
-The obstacle is a seam boundary: `presentResult(args, result)` is a **pure function of `args` + the model-facing `result` (`{content, isError}`)** — it runs on live streaming AND on session-log replay, so it must be replay-deterministic and cannot do I/O. It never sees the file's before/after content, and `FsEditOutcome`/`FsWriteOutcome` carried only a replacement count + version, not the text. So there was no way to compute — or even carry — an applied hunk to the presenter.
-
-## Decision
-
-Add a **persisted, tool-private presentation channel** so a tool's `execute` can attach a result-time render payload that survives replay, and use it to carry the applied-hunk diff.
-
-### 1. A replayable presentation projection on canonical tool output (core)
-
-The original implementation let `execute` return `{ content, meta }`. The [canonical tool-output contract](2026-07-20-canonical-tool-output-contract.md) supersedes that authoring shape: every tool now returns one schema-declared JSON value, `output.render(args, value)` derives model-facing blocks, and optional `output.presentationMeta(args, value)` derives replayable UI data.
-
-`presentationMeta` is tool-owned `JsonValue` that the core persists without interpreting its fields. `Session.append` validates it with the rest of the event, and replay passes the stored payload back to `presentResult`; presentations therefore reproduce without I/O or recomputation. The canonical value itself remains execution-local and is not added to the session format.
-
-This remains the general shape ("a tool projects durable result presentation"), not an fs-specific one—any tool can use it.
-
-### 2. The tool computes the hunk; the backend returns before/after (fs)
-
-Per the [capability-seam split](2026-06-13-capability-seams.md), the storage backend returns only **storage facts** and the model-facing tool owns **presentation**:
-
- `dsh-fs` widens `FsEditOutcome` with `{ before: string; after: string }` and `FsWriteOutcome` with `{ before: string | null; after: string }` (`before: null` ⇒ a create, or an existing-but-undiffable binary/non-UTF-8 file). The local backend already holds both texts at write time; it returns them as raw LF-normalized text, with **no diff/UI concept** entering the seam.
- `dsh-tool-fs` returns canonical before/after mutation facts and projects contextual hunks as `meta: { diffs: FileDiff[] }`. Successful mutations complete with a diff view: creates or unchanged overwrites fall back to an args-derived whole-file diff, while edits use applied hunks. Failed mutations carry no diff metadata and render their error normally.
-
-### 3. UI transports render a `diff` result view
-
-`ToolResultView` includes `DiffResultView { card:'diff'; title?; diffs: FileDiff[] }`. TUI and JSON-RPC/Web consumers switch on the same tagged view and replace the pending call's context-free snippet with the applied result hunk. The [automation-only ACP bridge](../simplification/2026-07-23-acp-automation-only-protocol.md) does not carry tool presentation.
-
-## Alternatives considered
-
-**Hand-rolling or vendoring the diff algorithm.** Contextual hunks have established edge cases, so `dsh-tool-fs` uses the typed [`diff`](https://www.npmjs.com/package/diff) package and normalizes `structuredPatch` output in one module. The repository's vendoring policy applies to its framework source, not every leaf utility.
-
-## Consequences
-
-`tool/result` events carry a tool-private `meta` payload—part of the on-disk vocabulary, runtime-gated to JSON by `Session.append`—and any tool can project durable result presentation without another core change. The diff card reproduces on session reload and snapshot replay for free: it is read back from the log, never recomputed. The costs: an overwrite holds both the prior and new text in memory to compute a UI-only hunk (`TODO(overwrite-diff-bound)`), and `dsh-tool-fs` carries a small, well-known runtime dependency.
-
-## Non-goals
-
- **Live incremental diff streaming.** The hunk is computed once, after the mutation completes; there is no per-keystroke diff.
- **Diffing a binary/non-UTF-8 overwrite.** `before` is `null` for such a file (it has no text diff basis); the write still succeeds and the result renders a whole-file diff (`oldText: null`) rather than a contextual hunk.
- **Rename/move diffs.** Only content diffs of a single resolved path.
- **Bounding the overwrite diff basis.** An overwrite reads the whole prior file into memory to compute the contextual hunk (on top of the new content already held), so a very large text overwrite allocates both texts for a UI-only diff. A future refinement can bound the pre-read and fall back to a whole-file / no contextual diff above a size threshold; tracked as `TODO(overwrite-diff-bound)` at the read site.

- Completes the one remaining representation difference named as a non-goal in [Tagged render-intent union](2026-07-02-tool-render-intent-union.md) — that Agent Note's Non-goals section is updated to record that applied-hunk diffs shipped here.
- Builds on the [filesystem capability seam](2026-06-17-filesystem-capability-seam.md) (the before/after are storage facts the backend returns) and [event-sourced sessions](2026-06-11-event-sourced-sessions.md) (the `meta` payload persists on the `tool/result` event, so replay reproduces the card).
- The `meta` channel is deliberately generic: a future tool (a structured search, a data-table result) can attach its own durable result presentation without another core change.

-## 问题
-
-[带标签的 render-intent 联合类型](2026-07-02-tool-render-intent-union.md)为 `dsh-tool-fs` 的 write/edit 在调用时刻提供 `card:'diff'`，纯粹从工具参数推导：write ⇒ `{oldText:null, newText:content}`（整个新文件），edit ⇒ `{oldText:old_string, newText:new_string}`（裸替换片段）。UI 可以将其渲染为行内 diff，但这是一个**无上下文**的 diff：裸的 `old_string`→`new_string` 没有周围行，而一次触及五个分散位置的 `replace_all` 仍然渲染为一对片段。
-
-在对接 `claude-agent-acp` 自身的 ACP（Agent Client Protocol） bridge 时可以看到完整编辑器 diff 的样子：变更应用后，它发出第二个 `tool_call_update`，其 diff 是**带 ±3 行上下文的 applied hunk**（`replace_all` 的每个变更位置各一个 hunk），由工具的 `structuredPatch` 重建。这个结果时刻的 hunk 正是让 Zed 在文件中*原位*显示变更（而非浮动片段）的关键。我们的工具止步于调用时刻的片段；完成后的结果只携带纯文本「updated successfully」，没有 diff。
-
-障碍在于一个 seam 边界：`presentResult(args, result)` 是 **`args` + 面向模型的 `result`（`{content, isError}`）的纯函数**——它在实时流式输出和会话日志回放中都会运行，因此必须具备回放确定性且不能做 I/O。它看不到文件的前后内容，而 `FsEditOutcome`/`FsWriteOutcome` 只携带替换计数和版本号，没有文本。因此无法计算——甚至无法携带——applied hunk 给 presenter。
-
-## 决策
-
-添加一个**持久化的、工具私有的展示通道**，使工具的 `execute` 能附加一个结果时刻的渲染载荷并在回放中存活，并用它来携带 applied-hunk diff。
-
-### 1. 规范工具输出上的可回放展示投影（core）
-
-原始实现允许 `execute` 返回 `{ content, meta }`。[规范工具输出契约](2026-07-20-canonical-tool-output-contract.md)取代了这种编写形态：每个工具如今返回一个由 schema 声明的 JSON 值，`output.render(args, value)` 从中派生面向模型的内容块，可选的 `output.presentationMeta(args, value)` 则派生可回放的 UI 数据。
-
-`presentationMeta` 是工具自有的 `JsonValue`，core 会持久化它，但不解释其中的字段。`Session.append` 将它与事件的其余部分一并校验，回放再把存储的载荷传回 `presentResult`；因此展示无需 I/O 或重新计算即可复现。规范值本身只存在于执行期间，不会加入会话格式。
-
-这仍是通用形态（「工具投影持久化的结果展示」），而非 fs 特有；任何工具都可以使用。
-
-### 2. 工具计算 hunk；后端返回 before/after（fs）
-
-按照 [capability-seam 拆分](2026-06-13-capability-seams.md)，存储后端只返回**存储事实**，面向模型的工具拥有**展示**：
-
- `dsh-fs` 将 `FsEditOutcome` 扩展为包含 `{ before: string; after: string }`，将 `FsWriteOutcome` 扩展为包含 `{ before: string | null; after: string }`（`before: null` 表示创建，或已存在但不可 diff 的二进制/非 UTF-8 文件）。本地后端在写入时已持有两份文本；它以原始 LF 规范化文本返回，**不让任何 diff/UI 概念进入 seam**。
- `dsh-tool-fs` 返回规范的变更前／后事实，并将上下文 hunk 投影为 `meta: { diffs: FileDiff[] }`。成功的变更以 diff 视图完成：创建或无变化的覆写回退到由参数推导的整文件 diff，而编辑使用 applied hunk。失败的变更不携带 diff 元数据，正常渲染其错误信息。
-
-### 3. UI 传输层渲染 `diff` 结果视图
-
-`ToolResultView` 包含 `DiffResultView { card:'diff'; title?; diffs: FileDiff[] }`。TUI 与 JSON-RPC/Web 消费方在同一个带标签的视图上做 switch，用 applied 结果 hunk 替换待定调用的无上下文片段。[仅面向自动化的 ACP 桥接层](../simplification/2026-07-23-acp-automation-only-protocol.md)不承载工具展示。
-
-## 曾考虑的替代方案
-
-**手写或 vendor diff 算法。** 上下文 hunk 有已知的边界情况，因此 `dsh-tool-fs` 使用带类型的 [`diff`](https://www.npmjs.com/package/diff) 包，并在一个模块中规范化 `structuredPatch` 输出。仓库的 vendor 策略适用于框架源码，而非每个叶子工具库。
-
-## 后果
-
-`tool/result` 事件携带工具私有的 `meta` 载荷；它属于磁盘格式词汇的一部分，由 `Session.append` 在运行时限制为 JSON。任何工具都可以投影持久化的结果展示，无需再改 core。diff 卡片在会话重载和快照回放时免费复现：它从日志中读回，从不重新计算。代价：覆写操作在内存中同时持有旧文本和新文本以计算仅用于 UI 的 hunk（`TODO(overwrite-diff-bound)`），且 `dsh-tool-fs` 引入了一个小型、知名的运行时依赖。
-
-## 非目标
-
- **实时增量 diff 流式输出。** hunk 在变更完成后一次性计算；没有逐键 diff。
- **对二进制/非 UTF-8 覆写做 diff。** 此类文件的 `before` 为 `null`（没有文本 diff 基础）；写入仍然成功，结果渲染整文件 diff（`oldText: null`）而非上下文 hunk。
- **重命名/移动 diff。** 仅限单个已解析路径的内容 diff。
- **限制覆写 diff 基础的大小。** 覆写操作将整个旧文件读入内存以计算上下文 hunk（加上已持有的新内容），因此非常大的文本覆写会为仅 UI 用途的 diff 分配两份文本。未来的改进可以设定预读上限，超过阈值时回退到整文件/无上下文 diff；在读取位置以 `TODO(overwrite-diff-bound)` 跟踪。
-
-## 相关

- 补全了[带标签的 render-intent 联合类型](2026-07-02-tool-render-intent-union.md)中作为非目标列出的最后一项表示差异——该 Agent Note 的「非目标」一节已更新，记录 applied-hunk diff 在此处交付。
- 基于[文件系统 capability seam](2026-06-17-filesystem-capability-seam.md)（before/after 是后端返回的存储事实）和[事件溯源会话](2026-06-11-event-sourced-sessions.md)（`meta` 载荷持久化在 `tool/result` 事件上，因此回放可复现卡片）。
- `meta` 通道有意设计为通用的：未来的工具（结构化搜索、数据表结果）可以附加自己的持久化结果展示而无需再改 core。

-# Agent Note: Add direct directory listing to the filesystem seam
-
-Status: implemented
-Archived: 2026-07-26
-
-English | [中文](2026-07-03-filesystem-directory-listing-seam.zh.md)
-
-## Problem
-
-`@deepseek-ai/dsh-fs` is the provider seam for filesystem access, with local and future non-local backends behind the same `ctx.fs` contract. Before this change it could resolve paths, stat targets, read text, stream text, write text, and edit text. That was enough for model-facing file tools, but not for non-model-facing consumers that need to enumerate directories without importing `node:fs`.
-
-The immediate pressure came from skill loading: reading an individual `SKILL.md` can already go through `ctx.get('fs')`, but discovering which skill roots contain `<name>/SKILL.md` or `<name>.md` still needs directory enumeration. Adding directory listing only in `dsh-skill` would either keep a direct Node dependency there or invent a one-off local helper outside the filesystem provider stack.
-
-This decision adds the provider capability without a model-facing `ls`/`list` tool or skill-discovery change. Those consumers require separate UX, prompt, and policy decisions.
-
-## Decision
-
-Add `FileSystem.listDir(target, signal?)` to `@deepseek-ai/dsh-fs`.
-
-`listDir` lists one directory level only. It returns direct children in stable name order and includes:
-
- `name`: the child basename.
- `type`: `file`, `directory`, or `other`.
- `target`: the resolved child `FsTarget`.
- `version`: cheap metadata when available.
- `size`: regular-file size when available.
-
-It never reads file contents. Recursive traversal, globbing, pagination, search, file watching, and model-facing rendering are intentionally out of scope.
-
-The local backend implements this through `readdir({ withFileTypes: true })`, `resolveLocalTarget`, and metadata `stat`/`realpath` probes. The result order is deterministic (`name.localeCompare`) to keep prompt/listing output stable for future consumers and improve prefix-cache reuse.
-
-Broken or disappeared children may be represented as `type: 'other'` without `version`/`size`; they do not abort the whole listing. Permission or backend I/O failures while listing the directory or resolving/probing child metadata fail the whole listing with structured `FsError` codes:
-
- `FS_NOT_FOUND` for missing targets.
- `FS_NOT_DIRECTORY` for existing non-directory targets.
- `FS_PERMISSION_DENIED` for permission failures.
- `FS_IO_ERROR` for other backend I/O failures.
- `FS_ABORTED` for aborted calls.
-
-## Alternatives considered
-
-**Add a model-facing list tool with the seam.** Rejected because its prompt, schema, and rendering contracts are independent of the provider primitive.
-
-**Keep directory enumeration in each consumer.** Rejected. That would bind product packages such as `dsh-skill` to Node/local filesystem behavior and bypass policy/remote/sandboxed backends.
-
-**Make `listDir` recursive or glob-shaped.** Rejected for now. Skill-root discovery only needs direct children, and a simple direct listing is the smallest backend contract future consumers can safely compose.
-
-**Skip children that fail metadata resolution.** Rejected. The API promises resolved child targets, so permission/IO failures while resolving a child are contract failures. Broken or disappeared children are the exception because they can still be represented without claiming a live resolved file.
-
-## Consequences
-
-Every filesystem backend must now implement one additional provider primitive. That is deliberate foundation work while the harness is still unreleased, but it does mean future sandboxed/remote backends need to define equivalent direct-child listing behavior.
-
-The capability remains provider-facing. Until a consumer lands, ACP/model sessions will still need existing tools such as `bash` for directory listing. The absence of a model-facing `listdir` tool is expected, not a wiring failure.

-# Agent Note: 为文件系统 seam 添加直接目录列举能力

-
-## 问题
-
-`@deepseek-ai/dsh-fs` 是文件系统访问的提供方 seam，本地后端与未来的非本地后端共享同一个 `ctx.fs` 契约。在本次变更之前，它能解析路径、stat 目标、读取文本、流式读取文本、写入文本和编辑文本。这对面向模型的文件工具已经足够，但对于需要枚举目录而又不想直接导入 `node:fs` 的非模型侧消费方来说还不够。
-
-直接的压力来自 skill（技能）加载：读取单个 `SKILL.md` 已经可以走 `ctx.get('fs')`，但发现哪些 skill 根目录包含 `<name>/SKILL.md` 或 `<name>.md` 仍需要目录枚举。如果仅在 `dsh-skill` 中添加目录列举，要么保留对 Node 的直接依赖，要么在文件系统提供方栈之外发明一个一次性的本地辅助函数。
-
-本决策只添加提供方能力，不涉及面向模型的 `ls`/`list` 工具或 skill 发现机制的变更。那些消费方需要独立的 UX、提示词与策略决策。
-
-## 决策
-
-在 `@deepseek-ai/dsh-fs` 中添加 `FileSystem.listDir(target, signal?)`。
-
-`listDir` 仅列举一层目录。它以稳定的名称顺序返回直接子项，包含以下字段：
-
- `name`：子项的 basename；
- `type`：`file`、`directory` 或 `other`；
- `target`：已解析的子项 `FsTarget`；
- `version`：可用时返回的轻量元数据；
- `size`：可用时返回的常规文件大小。
-
-它从不读取文件内容。递归遍历、glob 匹配、分页、搜索、文件监听和面向模型的渲染均有意不在范围内。
-
-本地后端通过 `readdir({ withFileTypes: true })`、`resolveLocalTarget` 以及元数据 `stat`/`realpath` 探测来实现。结果顺序是确定性的（`name.localeCompare`），以保持未来消费方的提示词/列表输出稳定，并提高前缀缓存复用率。
-
-损坏或已消失的子项可以表示为 `type: 'other'`（不带 `version`/`size`）；它们不会中止整个列举。在列举目录或解析/探测子项元数据时遇到权限或后端 I/O 故障，则以结构化的 `FsError` 错误码使整个列举失败：
-
- `FS_NOT_FOUND`：目标不存在；
- `FS_NOT_DIRECTORY`：目标存在但不是目录；
- `FS_PERMISSION_DENIED`：权限不足；
- `FS_IO_ERROR`：其他后端 I/O 故障；
- `FS_ABORTED`：调用被中止。
-
-## 曾考虑的替代方案
-
-**在添加 seam 的同时添加面向模型的 list 工具。** 否决。其提示词、schema 和渲染契约与提供方原语相互独立。
-
-**让每个消费方自行枚举目录。** 否决。这会将 `dsh-skill` 等产品包绑定到 Node/本地文件系统行为上，绕过策略/远程/沙箱后端。
-
-**让 `listDir` 支持递归或 glob 形式。** 暂时否决。skill 根发现只需要直接子项，而简单的单层列举是未来消费方可以安全组合的最小后端契约。
-
-**跳过元数据解析失败的子项。** 否决。API 承诺返回已解析的子项 target，因此解析子项时的权限/IO 故障属于契约失败。损坏或已消失的子项是例外，因为它们仍可在不声称拥有一个活跃已解析文件的前提下被表示。
-
-## 后果
-
-每个文件系统后端现在必须多实现一个提供方原语。这是 harness 尚未发布时有意为之的基础工作，但也意味着未来的沙箱/远程后端需要定义等价的直接子项列举行为。
-
-该能力仍停留在提供方层面。在消费方落地之前，ACP（Agent Client Protocol）/模型会话仍需使用 `bash` 等既有工具来列举目录。缺少面向模型的 `listdir` 工具是预期行为，而非接线错误。

-# Agent Note: Windows write-permission semantics — inherited DACLs, not mode bits
-
-Status: implemented
-Archived: 2026-07-26
-
-English | [中文](2026-07-05-windows-fs-permissions.zh.md)
-
-The replacement-file decision in this record is superseded by [Windows DACL preservation](../bug-fix/2026-07-19-windows-atomic-write-dacl-preservation.md).
-
-## Problem
-
-`writeFileAtomic` in `@deepseek-ai/dsh-fs-local` protects write-in-progress content with POSIX mode bits: the staging directory is created `0o700`, the temp file is opened `0o600`, and new files default to `0o600`. On POSIX this keeps temporary content owner-only regardless of the parent directory's permissions.
-
-Windows has no working equivalent behind the same API. Node's `chmod` there drives only the read-only attribute (every mode this package passes carries owner-write, so the calls are benign no-ops), and `stat().mode` reports synthetic `0o666`/`0o444` bits. The real security state is the file's DACL: a newly created file or directory inherits from its parent, while replacement needs the explicit handling owned by the superseding Agent Note.
-
-## Decision
-
-New Windows files use directory inheritance rather than synthetic mode bits: the staging directory is created inside the target's parent directory (`dirname(absolutePath)`), so it and the temp file inherit the destination directory's DACL. Replacement files follow the stricter [DACL preservation contract](../bug-fix/2026-07-19-windows-atomic-write-dacl-preservation.md).
-
-Tests assert mode bits on POSIX only. Native Windows coverage pins the package-owned replacement behavior; new-file inheritance remains an operating-system contract rather than a machine-specific ACL allowlist.
-
-## Alternatives considered
-
-**Explicit owner-only DACLs for new files.** Rejected because they would break inheritance and surprise users whose project directories are deliberately shared. Replacement writes copy the target's existing DACL rather than inventing an owner-only policy.
-
-**Test-side ACL verification.** A `Get-Acl` SID allowlist or `icacls` would verify Windows inheritance and the machine's `%TEMP%` ACL rather than package behavior; `icacls` also localizes well-known account names, making parsing locale-fragile.
-
-**Skip `chmod` on Windows.** Platform-guarding benign no-op calls adds branches without changing behavior.
-
-## Consequences
-
-POSIX keeps owner-only temp content regardless of the parent directory. A new Windows target inside a broadly accessible directory inherits that accessibility by design; a replacement retains the target's narrower DACL when one exists.
-
-Mode preservation across a replace degenerates to a no-op on Windows: a writable file probes as `0o666`, and replaying that through `chmod` leaves the read-only attribute clear. A read-only target cannot be replaced there because publication fails before the synthetic mode would matter.

-# Agent Note: Windows 写入权限语义：继承 DACL，而非权限模式位
-
-Status: implemented
-Archived: 2026-07-26

-[English](2026-07-05-windows-fs-permissions.md) | 中文
-
-本记录中关于替换文件的决策已由 [Windows DACL 保留机制](../bug-fix/2026-07-19-windows-atomic-write-dacl-preservation.md)取代。
-
-## 问题
-
-`writeFileAtomic` 在 `@deepseek-ai/dsh-fs-local` 中使用 POSIX 权限模式位保护正在写入的内容：以 `0o700` 创建暂存目录，以 `0o600` 打开临时文件，新文件也默认使用 `0o600`。在 POSIX 上，无论父目录的权限如何，这些设置都能保证临时内容仅对所有者可见。
-
-Windows 在同一 API 背后没有可用的对等机制。Node 的 `chmod` 在 Windows 上只会驱动只读属性（此包传入的每种模式都包含所有者写权限，因此这些调用是无害的空操作），`stat().mode` 则报告合成的 `0o666`/`0o444` 权限位。真正的安全状态由文件的 DACL 决定：新建文件或目录会从父目录继承，替换操作则需要由取代本文的 Agent Note 所定义的显式处理。
-
-## 决策
-
-Windows 新建文件使用目录继承，而不使用合成的权限模式位：暂存目录在目标的父目录（`dirname(absolutePath)`）内创建，因此它和临时文件都会继承目标目录的 DACL。替换文件遵循更严格的 [DACL 保留契约](../bug-fix/2026-07-19-windows-atomic-write-dacl-preservation.md)。
-
-测试仅在 POSIX 上断言权限模式位。Windows 原生覆盖率锁定由本包（package）负责的替换行为；新文件继承仍属于操作系统契约，而不是针对特定机器的 ACL 允许清单。
-
-## 备选方案
-
-**为新文件显式设置仅所有者可用的 DACL。** 不予采纳，因为这会破坏继承，也会使特意共享项目目录的用户感到意外。替换写入会复制目标现有的 DACL，而不会自行设计仅所有者可用的策略。
-
-**在测试中验证 ACL。** `Get-Acl` SID 允许清单或 `icacls` 验证的是 Windows 继承机制以及当前机器的 `%TEMP%` ACL，而非包的行为；`icacls` 还会对知名账户名进行本地化，导致解析容易受语言区域影响。
-
-**在 Windows 上跳过 `chmod`。** 为无害的空操作调用增加平台守卫分支，不会改变任何行为。
-
-## 后果
-
-无论父目录的权限如何，POSIX 都会继续将临时内容限制为仅所有者可用。Windows 中的新目标如果位于广泛可访问的目录内，将按设计继承这种可访问性；如果替换目标存在更严格的 DACL，则会保留该 DACL。
-
-在 Windows 上，替换时的模式保留会退化为空操作：可写文件的探测结果为 `0o666`，通过 `chmod` 重放该模式会使只读属性继续保持清除状态。由于发布操作会在合成模式发挥作用前失败，Windows 上无法替换只读目标。

-# Agent Note: GUI layering and the RPC protocol — host/client layering by capability provider, the four-quadrant message model, and the fetch carrier
-
-Status: implemented
-Archived: 2026-08-27
-
-English | [中文](2026-07-19-gui-layering-and-rpc-protocol.zh.md)
-
-> Division of labor: this document = the layering model + the channel-independent RPC protocol; the protocol's Web implementation combines HTTP uplink with the [WebSocket downlink carrier](2026-08-04-websocket-downlink-carrier.md), while the browser object layer is in the [web client architecture note](2026-07-19-gui-web-client-architecture.md).
-
-## Problem
-
-We need a UI integration layer. Beyond the existing ACP/stdio baseline, more product clients are coming — Web (server), Electron, and others. We call them Clients and want the following capabilities:
-
- One `dsh` process supporting both `dsh web` (serve) and `dsh --profile headless` (headless) — one process, two modes (a design reservation)
- Launching inside Electron with the same Web technologies as `dsh web`
-
-That demands a stable layered responsibility model in the engineering codebase, so future clients plug in cleanly.
-
-At the same time the physical channels differ per consumer (browser HTTP/WebSocket, in-process fetch/SSE, IPC later), so we also need a channel-independent message model and a single contract source of truth — "adding a method" and "swapping a carrier" must not entangle each other, and every message on the wire must be type-validatable, observable, and reconcilable.
-
-## Decision
-
-### Layering
-
-Directories layer as follows:
-
- `packages/host/*`: packages provide host-side capability only (representing the Node.js engineering core built on the existing harness plugin system), and additionally
-    - the unified backend protocol (fetch, HTTP, streaming interfaces…) — definitions and support, see the "Message protocol" sections below
- `packages/client/*`: packages provide client-side capability only; every package stays single-sided. Three kinds live here (the axes are owned by the [client plugin loading note](2026-07-23-client-plugin-loading-model.md)):
-    - **Pure libraries** (`ui-slots`, `ui-primitives`, plus the `loader` kernel package): ordinary root-index packages, statically bundled into the shell; the two client libraries are seeded into the module table.
-    - **Static-arrival entry packages** (`connection`, `runtime`, `ui-theme`, `i18n`, `hmr`): no `dsh.client` key and no browser bundle — the shell bundles their `src/client/` half and registers it with `ctx.modules`; they are governed as entries of the host-authored graph like everything else.
-    - **Fetch-arrival plugin packages** (`ui-layout`, `ui-sidebar`, `ui-conversation`, `ui-trajectory`): dual-entry — the root index is the node half (an empty `apply`, existing so the host Loader governs lifecycle and the web plugin registry discovers the package.json `dsh.client` declaration); the implementation lives under `src/client/`, shipped as the `./client` subpath (a tsdown closure-factory bundle). Cross-plugin consumption of `/client` is type-only; value cooperation goes through cordis services.
- `apps/` holds the externally exported applications, assembled from Client / Host mixtures.
-    - `apps/web` (`dsh-web-frontend`) is the vite application: a thin `main.ts` over the shell API exported by `dsh-client-web`.
-    - `apps/cli` (`@deepseek-ai/dsh`) dispatches commands: `dsh web` = Host + webserver + the built `dsh-web-frontend` dist; `dsh --profile headless` = [a direct core Agent/Session entry point](2026-08-09-headless-direct-core-entry-point.md), with zero Host, HTTP, or browser layer.
-    - A future Electron application reuses the same web client packages over an IPC fetch carrier.
-
-```
-apps/*  (applications: apps/web = vite app, apps/cli = bin dispatch)
-  │ consume
-  ▼
-packages/host/*                      packages/client/*
-  apiproxy   front layer: protocol     pure libs: ui-slots / ui-primitives
-  runtime    assembly / host entity    dsh.client plugins ×8 (node half = empty apply,
-  webserver  Web HTTP carriage                              client half = src/client/)
-  │ ctx.plugin(...)                      ▲ import only apiproxy's /api /client subpaths
-  ▼                                      │ (type-only + the client base class)
-harness core packages ──────────────────┘ (types reach the browser via import type)
-```
-
-Direction discipline (every rule auditable from package deps):
-
- `runtime → apiproxy` is one-way; apiproxy depends only on type definitions.
- Client-side packages **never import** host-side package runtime (they consume only the two browser-safe subpaths `/api` and `/client`).
- `webserver` does not depend on `runtime`: it provides an implementation of the `{ fetch }` interface — "webserver ← runtime" is a runtime injection relationship, not a package dependency.
- Cross-package client imports use the `/client` subpath for plugin packages, and between plugin packages they are type-only — a cross-plugin value import is a build error at the tsdown purity gate (value cooperation goes through cordis services; the [client plugin loading note](2026-07-23-client-plugin-loading-model.md) owns the edge rules).
-
-TypeScript checks in **two aggregate programs** referenced by a solution root (`tsconfig.json` = solution; `tsconfig.host.json` = host side + tests, excluding `packages/client`; `tsconfig.client.json` = client packages and their tests): both sides merge the cordis `Context` interface under the same keys (`sessions`, `loader`) with different services, so one program would see both declaration merges and report a collision. Shared leaves (session/llm/tools/apiproxy…) build once and are referenced by both programs ([topology](../process/2026-07-22-tsconfig-solution-root-two-aggregates.md)).
-
-On the protocol side: TS interfaces (`packages/host/apiproxy/src/api/`, zero Node dependencies, browser-importable); wire messages unify under a **bidirectional model** — each logical message is classified by "who initiates × request/response" (two axes, four cells, called the four quadrants below), decoupled from the physical channel; clients all inherit `AbstractApiClient` (protocol invariants live entirely in the base class, platform differences are just the `doFetch` transport aspect).
-
-#### Layer roles
-
-| Layer | Package | Responsibility | Key discipline |
-|---|---|---|---|
-| Front layer | `dsh-host-apiproxy` | TS/zod definitions (api/) + the fetch abstraction (fetch/: handler + client base class) | Keep it simple — every consumer needs it; importable from Node and browser alike; protocol content in the "Message protocol" sections below; clients must not bypass api through ctx |
-| Assembly layer | `dsh-host-runtime` | Plugin composition + ApiProxy integration + the web UI plugin mount (in-memory Loader tree over the eight dsh.client packages); home of host-level configuration (defaults/persistenceRoot, future user profile) | Which plugins mount and with what defaults is decided only here; shells must not alter the assembly |
-| Carrier layer | `dsh-host-webserver` | Web HTTP and upgrade: static serving + `/api/*`→handler forwarding + WebSocket upgrade route + close semantics; plugin bundle endpoint + `__DSH_BOOT__` manifest injection (fed by the web plugin registry) | Web (browser access) only; zero workspace dependencies (the registry arrives by structural injection); Electron does not reuse it |
-| Client libraries | `dsh-client-ui-slots` / `dsh-client-ui-primitives` | Slot contracts / pure React atoms | Seeded into the loader module table by the shell |
-| Client plugins | `dsh-client-connection` / `dsh-client-runtime` / `dsh-client-ui-theme` / `dsh-client-ui-renderer` / feature UI packages | Browser-side Cordis plugin tree: wire consumer, core services, theme, React rendering, and feature composition — see the web client architecture note | Dual entry (node half = empty apply; implementation in `src/client/`); cross-plugin value cooperation uses services and slots |
-| Application | `@deepseek-ai/dsh` (apps/cli) + `dsh-web-frontend` (apps/web, the vite application) | Coarse bin dispatch + one assembly module per application (web.ts / headless.ts); the vite app is a thin main over the `dsh-client-web` shell surface | Applications use dynamic imports so they never load each other; workspace knowledge like dist location stays in the app |
-
-#### Naming rule
-
-Packages under `packages/host/*` and `packages/client/*` **must carry the directory-group prefix in the package name**: host/runtime → `dsh-host-runtime`, client/runtime → `dsh-client-runtime`. The directory name does not repeat the group prefix (host/ already expresses it). The package-name tail therefore ≠ the directory name, so the `dsh-*` wildcard in tsconfig.base.json (which resolves by directory name) misses them — **each package in these two groups needs an explicit paths entry**, including separate entries for the client packages' `/client` subpaths so source-level resolution matches the exports map.
-
-#### How to integrate a new application (operational checklist)
-
-1. **Pick a fetch impersonation**: browser same-origin HTTP / in-process `host.handler.fetch` injection / your own transport-aspect subclass (e.g. future Electron IPC, see the "Subclass table" below).
-2. **Write an assembly module under `apps/`**: `startHost()` + a client subclass + the application's private signal/print/exit semantics; a mixture never becomes a package — assembly is written in the app.
-3. **Import `dsh-host-webserver` only if you need HTTP carriage**, otherwise zero ports.
-
-The two existing applications preserve the division: the Web application mounts Host, carrier, and browser composition, while `dsh --profile headless` mounts a direct core runner with zero Host, HTTP, or ports. ACP-class protocol bridges do not follow the client-carrier checklist: they expose core to the external ecosystem and mount directly via `ctx.plugin(entry-point plugin)` without fetch.
-
-## Message protocol
-
-The sections from here down are the protocol body carried by the front layer (`dsh-host-apiproxy`). The wire has exactly four message kinds (the four quadrants) — the Web carriage in the right column is only an example; swapping the carrier (in-process/IPC) leaves the quadrants unchanged:
-
-```
-                 client 发起                      server 发起
-  request   ① ClientRequest                 ③ ServerRequest
-            （POST /api/<method> body）      （WebSocket message：session 事件、审批/问答 requested）
-  response  ② ServerResponse                ④ ClientResponse
-            （该 POST 的 HTTP 应答体）        （POST /api/respond body，回填 ③ 的 rpcId）
-```
-
-### Wire full forms: a four-member named discriminated union (`api/rpc.ts`)
-
-| Type | Discriminant tag | Fields | rpcId ownership | Web carriage |
-|---|---|---|---|---|
-| `ClientRequest` | `'client-request'` | `rpcId` `method` `payload` | client mints | `POST /api/<method>` body |
-| `ServerResponse` | `'server-response'` | `rpcId` `result` | echoes ① | that POST's response body (always HTTP 200) |
-| `ServerRequest` | `'server-request'` | `rpcId` `method` `payload` | server mints | WebSocket text message |
-| `ClientResponse` | `'client-response'` | `rpcId` `result` | echoes ③ | `POST /api/respond` body |
-
-`RpcMessage = ClientRequest | ServerResponse | ServerRequest | ClientResponse`, narrowed via `switch (message.type)`.
-
-**rpcId discipline** (`RpcId` is a branded string with constructor `RpcId()`):
-
- Whoever initiates mints; a response always echoes the corresponding request's rpcId and **never mints a new id**.
- server-requests split into two kinds, distinguished statically by `method` (= the frame type), with **no third kind**: answerable frames (`approval/requested`, `question/requested`) carry a stable logical request id (minted once on acceptance, reused verbatim on baseline replay, echoed by the client's answer); pure-push frames (`session/event` etc.) carry an rpcId identifying that one push (freshly minted each time).
- Business code never mints: unary minting funnels into the client base class `callUnary`, frame minting funnels into the host side.
-
-### Signature narrow forms and carrier completion
-
-Domain interface signatures perceive only the narrow forms: `RpcRequest<P> = { rpcId, payload }`, `RpcResponse<T> = { rpcId, result: RpcResult<T> }`. The carrier layer completes narrow forms into full forms (adding the `type` tag and `method`); direction is never inferred from the channel. `RpcResult<T> = { ok: true; value } | { ok: false; error: RpcError }` — methods do not throw business errors.
-
-### RpcReceipt: the carrier receipt
-
-The HTTP response body of a `ClientResponse` is `RpcReceipt = { accepted: true } | { accepted: false; reason: 'not-pending' | 'bad-response' }` — a carrier-layer receipt, **not** an RpcMessage (a response has no response); late/duplicate answers get `not-pending`, and the logical convergence point is the `*/resolved` frames.
-
-## The type system: signatures are the source of truth
-
-### RpcMethodMap and derived generics (`api/rpc-map.ts`)
-
-Method parameter/return structures **live only in the interface method signatures**; the map registers the methods themselves; every other position (handler, client, store, tests) references the derived generics — copying literals or introducing flat named types is banned:
-
-```ts ignore-check
-export interface RpcMethodMap {
-  'session.list': SessionsApi['list']        // map key 即 wire 路径段
-  // …其余方法同形登记，全集见 api/rpc-map.ts
-}
-// 派生泛型（穿透窄形取业务类型；实际声明带 K extends keyof RpcMethodMap 约束）
-export type RequestPayload<K> = Parameters<RpcMethodMap[K]>[0]['payload']
-export type ResponseValue<K> =
-  Awaited<ReturnType<RpcMethodMap[K]>> extends RpcResponse<infer T> ? T : never
-```
-
-Stream methods (`events.mux`/`events.host`) stay out of the map (not unary); `respond` stays out of the map (it is a client-response, not a method call).
-
-### The error model (`RpcErrorDetailsMap`)
-
-One example row of an error code:
-
-| code | details | when |
-|---|---|---|
-| `bad-request` | `{ issues: ZodIssue[] }` | wire/payload zod validation failed |
-
-The full code set is `RpcErrorDetailsMap` in `api/rpc.ts`. `RpcError` is the distributive union expanded from the map: `code` discriminates, `details` narrows automatically after a `switch`; **details is required** — a new code = one map row + one error-schema branch, and omission is a compile error. Transport failures (network down, host not up) are thrown by the carrier as exceptions; the two layers never mix.
-
-### Bidirectional zod validation and anchoring
-
- **Two-level parse**: the full-form schema once (type/rpcId/method structure + the handler checking path==method) → the business payload dispatched by method/frame type for a second parse; rejection = `bad-request`.
- **Anchoring**: schemas uniformly `satisfies z.ZodType<Wire<T>>` (`api/rpc.schema.ts`). `Wire<T>` is a deep "| undefined" widening — the repo enables `exactOptionalPropertyTypes` while zod `.optional()` outputs `T | undefined`, so anchoring the original type is unusable across the board; on the JSON wire, absence and undefined are indistinguishable, so the widening loses no validation semantics. Passthrough wide branches (`SessionEvent`/`ContentBlock`/frame unions/`RpcError`) and brand-id schemas use explicit casts with comments.
- Brand casts have one point each: every schema file funnels its id cast into one place (`rpcIdSchema` is the only cast point in rpc.schema.ts).
-
-## The contract face (ApiProxy)
-
-The root interface is `ApiProxy = { sessions, host, events, respond }` (`api/index.ts`). A new client-request domain = one new file pair (`<domain>.ts` + `<domain>.schema.ts`) + one root-interface field + one map row.
-
-### The unary method table
-
-One example row (the table structure is the reading key):
-
-| method key | request payload | return value | semantics |
-|---|---|---|---|
-| `session.list` | `{ cursor?: string }` (cursor is a reserved seat, unimplemented) | `{ items: SessionSummary[] }` | persisted sessions, updatedAt descending; v1 builds no index |
-
-The remaining methods (`session.create`/`session.history`/`session.rename`/`session.prompt`/`session.cancel`/`host.describe`) are not re-copied here — signatures are the source of truth; see `api/sessions.ts`, `api/host.ts`, and `RpcMethodMap`.
-
-### Frames (server→client, named unions)
-
-Two logical streams: the mux stream (`/api/events.mux`, all-session aggregate) and the host stream (`/api/events.host`, host-level events). The browser consumes one downlink WebSocket per stream, while the in-process fetch carrier retains SSE with the same event framing; see the [WebSocket downlink carrier](2026-08-04-websocket-downlink-carrier.md) for the physical boundary. One example frame row:
-
-| frame type | payload | when |
-|---|---|---|
-| `session/event` | `{ sessionId; event: SessionEvent }` | core passthrough: core events pass verbatim, `assistant/chunk` IS the token stream, no separate delta frame |
-
-The remaining frame types are not re-copied here; the full unions are `MuxFrame`/`HostFrame` in `api/events.ts`. Three semantic points to know: `session/subscribed` carries lastSeq for history-race detection; the `approval/question` requested frames are answerable (stable rpcId) and the resolved frames are the convergence surface; `host/agent-error` is the only outlet for live failures with no turn position.
-
-**Passthrough discipline**: events/messages/content blocks on the wire ARE the core types (`SessionEvent`/`ContentBlock`) — no second DTO set; types reach the browser through the `import type` dependency chain. `SessionEventMap` is merge-extensible: the client applies its documented default (ignore) to unknown types, and the event schema keeps a "valid envelope + unknown type" branch — the envelope stays strict; this is not field-level passthrough.
-
-### Session semantics (impl-side commitments)
-
- **History = event replay**: one fold (client side); history pagination and live increments share one code path; the server maintains no second materialized-snapshot system. History **page boundaries align to message boundaries** (never cut mid-message; chunks group with their finalized message), and the tail page includes the in-flight partial's chunks.
- **Prompt correlation**: the prompt's rpcId rides MessageSource (`'user-rpc'`) into the `user/message` event; the client uses it to promote the optimistic echo.
- **Reconnect = rebuild**: no resume cursor (`mux`'s `since` signature is a reserved seat, ignored if passed); on disconnect reopen the stream + refetch history; compare `subscribed.lastSeq` with the history tail seq and backfill once if there is a gap.
- **Cold session handling follows ownership**: `session.history` and the source read for `session.fork` inspect persistence without an Agent, while Agent-bound ordinary-session methods such as `prompt` resume through a deduplicated in-flight table. Session-backed subagents reject that generic resume path, and attachment status is not exposed to clients (`running` already covers it).
- **Approvals/questions**: the requested frame mints a stable rpcId on acceptance; first answer wins, and the host's in-memory pending table (keyed by rpcId) is the only referee; after a mux reopen, still-pending requested frames replay after the subscribed frame (rpcId reused verbatim — refresh recovery). The audit events `approval/asked`/`decided` continue through the durable log — frames = the live control plane, events = the durable audit. **Status**: the contract and frame types are shipped; the host-side pending table/wire answerer is unimplemented (`respond` in `api-proxy.ts` is a stub, always `not-pending`); PendingCard v1 is display-only.
- **No protocol version**: client and host release bound together; `host.describe` has no protocolVersion field; introduce one when an independently released client appears.
- **Reserved-method discipline**: the map holds only implemented methods; an unknown method fails loud at envelope parse (`bad-request`) — no not-implemented fallback code. The reservation list (implementing = copy the signature into the domain interface + add the map row + add the schema pair): `session.fork`, `prompt.mode` gaining `'inject'`, `task.list`, `host.listModels`, describe gaining `hostInstanceId`. (`session.rename` graduated from this list: it appends a user-source `session/title` event.)
-
-## The client carrier: the AbstractApiClient class family (`fetch/client.ts`)
-
-**Protocol invariants live in the base class; platform differences are two aspects**: the abstract method `doFetch(url, init)` (transport) + the overridable `onEnvelope` (observation).
-
-### IApiClient: the caller view
-
-The same domain tree as `ApiProxy`, but unary methods **take the business payload directly** — the carrier mints the rpcId and wraps the envelope; business code never mints, and code needing this call's rpcId reads it from the returned `RpcResponse` echo. `ApiProxy` is the narrow-form signature contract the impl side implements; `IApiClient` is the payload-direct view clients consume; `AbstractApiClient` bridges the two. Methods derive per key from `RpcMethodMap` — a map row addition updates them mechanically.
-
-### Protocol paths held by the base class
-
-| Path | Content |
-|---|---|
-| `callUnary` | mint → tap → POST full form → `serverResponseSchema` parse → **rpcId echo check** (mismatch throws) → tap → emit narrow form |
-| `readSse` | streaming fetch (not EventSource), `\n\n` framing, `data:` concatenation, ServerRequest full-form parse, tap, emit narrow `RpcRequest<frame>` |
-| `respond` | client-response passthrough (rpcId is an echo — never minted here); response body parsed by `rpcReceiptSchema` |
-| unary deadline | Ordinary unary calls use `AbortSignal.timeout` (default 30s, constructor-tunable); user-paced `host.pickDirectory` and `command.execute` omit that deadline but keep caller/connection cancellation; streams have no deadline |
-| `resolveBase` | browser = same-origin origin; no-location environment (Node) = the `http://dsh.internal` fake authority |
-
-### The instance-level envelope observation aspect
-
-All four quadrant full forms pass through `onEnvelope`; the base implementation is an **instance-owned microtask-batched buffer** (frame storms must not disturb consumers per frame; module-level state would leak across instances/tests, hence instance-owned). Observers subscribe via `subscribeEnvelopes(listener)` (receiving whole batches as `readonly RpcMessage[]`, returning an unsubscribe function); a listener throw is isolated (observation must never bite the carrier). With no subscribers the buffering costs nothing. No shipped consumer subscribes — the aspect is the designated seat for wire diagnostics (the retired RPC debug panel was its first consumer, and a future one plugs in without touching the carrier).
-
-### The subclass table (transport carriage)
-
-| Subclass | Package | doFetch | Purpose |
-|---|---|---|---|
-| `InProcessApiClient` | apiproxy itself | the injected `{ fetch }` handler | **The isomorphic point**: `new InProcessApiClient(toFetchHandler(api))` never touches the network yet runs the real wire serialization/zod/SSE framing; carrier tests and callers can exercise the protocol without opening a port, while product `dsh --profile headless` drives core directly |
-| `WebApiClient` | dsh-client-connection | `globalThis.fetch` uplink + one same-origin WebSocket downlink per logical stream | the browser client; physical boundary in the [WebSocket downlink carrier](2026-08-04-websocket-downlink-carrier.md) |
-| `FixtureApiClient` | dsh-client-connection | unused (protocol-layer override) | serverless UI development (`?fixture`): overrides the `callUnary`/`openMux`/`openHost`/`respond` virtuals and is itself the fake server (frame rpcIds minted by it, semantics self-consistent) |
-| IPC bridge subclass (hypothetical example — no such shell exists) | an Electron shell | IPC serialization round trip | would swap only doFetch; contract and base class unchanged |
-
-## How to extend (operational checklists)
-
-**Add a unary method (5 steps)**: ① add the method signature to the domain interface (parameters/return inline — this is the single source of truth); ② add one `RpcMethodMap` row; ③ add the request/value schema pair in `<domain>.schema.ts` (anchored `Wire<RequestPayload<'…'>>`); ④ add one handler `UNARY_ROUTES` row (the handler's Web carriage is in the web client architecture note); ⑤ implement in the impl (echo `request.rpcId`). On the client side, add the passthrough row to the `IApiClient`/`AbstractApiClient` domain method tables.
-
-**Add a frame type (3 steps)**: ① add a branch to the `MuxFrame`/`HostFrame` union (answerable frames must note the stable-rpcId semantics); ② add a frame-schema branch; ③ the consumers' fold/routing documented-default already covers unknown types — add an explicit branch as needed.
-
-**Add an error code (2 steps)**: ① add one `RpcErrorDetailsMap` row (details required); ② add one `rpcErrorSchema` discriminatedUnion branch.
-
-**Plug in a new carrier**: subclass `AbstractApiClient` implementing only `doFetch`; to intercept at the protocol layer (like the fixture), override the `callUnary`/`openMux`/`openHost` virtuals instead. Contract and base class stay unchanged.
-
-**Promote a reserved method**: copy the reserved signature into the domain interface → add the map row → add the schema pair → add the UNARY_ROUTES row → implement.
-
-## Consequences
-
-Every client consumes one contract: adding a unary method is a five-step mechanical change from a single signature, swapping a carrier touches only a `doFetch` subclass, and every wire message is zod-validated, observable through the envelope tap, and reconcilable by rpcId. Ordinary unary calls remain bounded, while `host.pickDirectory` and `command.execute` may stay pending until the operation finishes or caller/connection cancellation arrives; this accepts that a non-cooperative user-paced operation can hang its request rather than treating valid operation duration as transport failure. The other accepted costs: two groups of packages need explicit tsconfig paths entries, and the reserved methods (fork/inject/task.list/listModels/hostInstanceId) stay dormant until a real consumer arrives.
-
-## Alternatives considered
-
-| Rejected | One-line reason |
-|---|---|
-| Packaging by product (a web family, an electron family) | Products share host/client capabilities rather than an application implementation; capability-provider layering means a new application needs zero new packages |
-| A package per mixture (e.g. a standalone headless package) | A mixture has exactly one consumer (its own app); packaging it is ownerless abstraction, while assembly in the app is readable and disposable |
-| Consuming clients connecting to ctx directly (skipping the apiproxy layer) | Clients require wire validation, observability, and multi-client consistency. Direct headless is a local entry point with no client boundary and uses the public Agent/Session seams rather than a client command plane |
-| webserver depending on runtime (saving the handler injection) | Structural-typing injection keeps webserver reusable by sidecars/tests with zero workspace deps; a package dependency would drag assembly knowledge into the carrier layer |
-| Package names without the group prefix (continuing dsh-<tail>) | `dsh-runtime`/`dsh-web-ui` lose their belonging in the flat npm namespace; the cost is one explicit paths entry per package |
-| Reusing the in-repo JSON-RPC 2.0 (dsh-sdk-jsonrpc-server) | Numeric error codes degrade to a single fallback code, contracts get aligned by hand in two copies, and naming drifts without a convention |
-| A three-envelope model (Request/Response/Frame envelopes, signatures direction-blind) | rpcId correlation is logical-layer; frame and response direction semantics inferred from the channel break the moment the carrier changes |
-| Named Request/Response type pairs as the source of truth (map registering type pairs) | Flat named types are a second name for the same fact; signature inference makes adding a method a one-place change |
-| REST-style paths | The consumer is our own client with no third-party REST expectations; RPC mapping straight onto the method table is more mechanical |
-| A DTO layer (a second wire-only structure set) | Core types reach the browser type-only at zero cost; a DTO is a permanent two-way synchronization tax |
-| Cursor resumption (implementing mux since) | Reconnect = rebuild (opencode-style) covers all v1 needs; the signature keeps the seat, implementation waits for a real consumer |
-| A createApiClient factory function (the original implementation) | Platform differences (transport/observation) are inheritance aspects, not parameters; the class family lets the fixture substitute at the protocol layer instead of wrapping a fake envelope |
-| Applying the 30-second transport deadline to `command.execute` | Command duration is operation work, not a transport-health budget; the deadline kills valid long-running handlers, while caller/connection cancellation already supplies the required stop path |

-> 分工线：本篇 = 分层模型 + 通道无关的 RPC 协议；协议的 Web 实现由 HTTP 上行加 [WebSocket 下行载体](2026-08-04-websocket-downlink-carrier.zh.md)组成，浏览器对象层见 [Web 客户端架构笔记](2026-07-19-gui-web-client-architecture.zh.md)。
-
-## Problem
-
-需要提供 UI 对接层，除已有 ACP（Agent Client Protocol）/stdio 基线外，还需要 Web（server）、Electron 等其他产品客户端。我们把它们统一称为 Client。希望具备以下能力：
- 一个 `dsh` 进程同时支持 `dsh web`（启动）和 `dsh --profile headless`（headless），一个进程两种模式（设计预留）
- 在 Electron 中使用与 `dsh web` 相同的 Web 技术启动
-
-那么当前的工程代码需要稳定的分层职责模型，便于以后接入各类 client。
-
-同时各消费方的物理通道不同（浏览器 HTTP／WebSocket、进程内 fetch/SSE、将来 IPC），还需要一个通道无关的消息模型和单一约定真源，让「加一个方法」「换一种载体」互不牵连，且 wire 上的每条消息可类型校验、可观测、可对账。
-
-## Decision
-
-### 分层
-
-目录按照如下分层：
- `packages/host/*`：包只提供 Host 侧能力（代表了以现在 Harness 实体插件系统为主体的 Node.js 代码核心工程），除此之外，还包含
-    - 统一后端协议（fetch、HTTP、流式接口等）定义和支持，见本篇「消息协议」起各节
- `packages/client/*`：包只提供 Client 侧能力，每包单边不混。这里住三类包（两条轴归 [client 插件装载笔记](2026-07-23-client-plugin-loading-model.zh.md) 所有）：
-    - **纯库**（`ui-slots`、`ui-primitives`，外加内核包 `loader`）：普通根入口包，静态打包进壳；两个客户端库播种进模块表。
-    - **静态到达 entry 包**（`connection`、`runtime`、`ui-theme`、`i18n`、`hmr`）：无 `dsh.client` 键、无浏览器 bundle——壳把它们的 `src/client/` 半边打进自己的 bundle 并向 `ctx.modules` 登记；它们与其余单元一样，作为 host 独家撰写的图里的 entry 受治理。
-    - **fetch 到达插件包**（`ui-layout`、`ui-sidebar`、`ui-conversation`、`ui-trajectory`）：双入口——根入口是 node 半边（空 `apply`，其存在是为了让 host Loader 管辖生命周期、让 web 插件注册表发现 package.json 的 `dsh.client` 声明）；实现住在 `src/client/` 下，经 `./client` 子路径发布（tsdown 闭包工厂 bundle）。跨插件消费 `/client` 只限类型；值层面的协作走 cordis 服务。
- `apps/` 作为对外导出的应用入口，可以由 Client / Host 混合组装。
-    - `apps/web`（`dsh-web-frontend`）是 vite 应用：`dsh-client-web` 导出的壳 API 之上的一层薄 `main.ts`。
-    - `apps/cli`（`@deepseek-ai/dsh`）分发命令：`dsh web` = Host + webserver + 构建出的 `dsh-web-frontend` dist；`dsh --profile headless` = [直接使用核心 Agent／Session 的入口](2026-08-09-headless-direct-core-entry-point.zh.md)，不含 Host、HTTP 或浏览器层。
-    - 将来的 Electron 应用经由 IPC fetch 载体复用同一套 web client 包。
-
-```
-apps/*  (applications: apps/web = vite app, apps/cli = bin dispatch)
-  │ consume
-  ▼
-packages/host/*                      packages/client/*
-  apiproxy   front layer: protocol     pure libs: ui-slots / ui-primitives
-  runtime    assembly / host entity    dsh.client plugins ×8 (node half = empty apply,
-  webserver  Web HTTP carriage                              client half = src/client/)
-  │ ctx.plugin(...)                      ▲ import only apiproxy's /api /client subpaths
-  ▼                                      │ (type-only + the client base class)
-harness core packages ──────────────────┘ (types reach the browser via import type)
-```
-
-方向纪律（每条都由包 deps 可核）：
-
- `runtime → apiproxy` 单向；apiproxy 仅依赖类型定义。
- client 侧包**永不 import** host 侧包的运行时（只吃 `/api`、`/client` 两个浏览器安全子路径）。
- `webserver` 不依赖 `runtime`：它提供 `{ fetch }` 特定实现 ——「webserver ← runtime」只是运行时注入关系，不是包依赖。
- client 侧跨包 import 插件包一律走 `/client` 子路径，且插件包之间只限类型 import——跨插件值 import 在 tsdown 纯度门禁处即构建错误（值层面的协作走 cordis 服务；边规则归 [client 插件装载笔记](2026-07-23-client-plugin-loading-model.zh.md) 所有）。
-
-TypeScript 以 solution 根引用的**两个聚合 program** 检查（`tsconfig.json` = solution；`tsconfig.host.json` = host 侧 + 测试，排除 `packages/client`；`tsconfig.client.json` = client 各包及其测试）：两侧在相同键（`sessions`、`loader`）下以不同服务合并 cordis `Context` 接口，单一 program 会同时看到两份声明合并而报冲突。共享叶子包（session/llm/tools/apiproxy 等）只构建一次，由两个 program 共同引用（[拓扑](../process/2026-07-22-tsconfig-solution-root-two-aggregates.zh.md)）。
-
-协议侧：TS interface（`packages/host/apiproxy/src/api/`，零 Node 依赖，浏览器可 import）；wire 消息统一为**双向模型**——每条逻辑消息按「谁发起 × request/response」分类（两轴四格，后文称四象限），与物理通道解耦；客户端统一继承 `AbstractApiClient`（协议不变量全在基类，平台差异只是 `doFetch` 传输切面）。
-
-#### 分层角色
-
-| 层 | 包 | 职责 | 关键纪律 |
-|---|---|---|---|
-| 前置层 | `dsh-host-apiproxy` | TS/zod 定义 (api/)+ fetch 抽象 (fetch/：handler + 客户端基类) | 做简单、每个消费方都要；Node/浏览器皆可 import；协议内容见下文「消息协议」起各节；client 不得经 ctx 绕开 api |
-| 装配层 | `dsh-host-runtime` | 插件组合 + ApiProxy 集成 + web UI 插件挂载（覆盖八个 dsh.client 包的内存 Loader 树）；host 级配置归属地（defaults/persistenceRoot，将来用户 profile） | 装什么插件、给什么默认值只在这里定；壳不得改装配 |
-| 承载层 | `dsh-host-webserver` | Web HTTP 与 upgrade：静态服务 + `/api/*`→handler 转发 + WebSocket upgrade route + close 语义；插件 bundle 端点 + `__DSH_BOOT__` manifest（元数据清单）注入（由 web 插件注册表供给） | Web（浏览器访问）专用；零 workspace 依赖（注册表经结构注入到达）；Electron 不复用它 |
-| client 库 | `dsh-client-ui-slots` / `dsh-client-ui-primitives` | slot 约定 / 纯 React 原子组件 | 由壳播种进 loader 模块表 |
-| client 插件 | `dsh-client-connection` / `dsh-client-runtime` / `dsh-client-ui-theme` / `dsh-client-ui-renderer` / 功能 UI 包 | 浏览器侧 Cordis 插件树：wire 消费方、核心服务、主题、React 渲染与功能组合——见 Web 客户端架构笔记 | 双入口（node 半边=空 apply；实现在 `src/client/`）；跨插件值协作经服务与 slot 完成 |
-| 应用 | `@deepseek-ai/dsh`（apps/cli）+ `dsh-web-frontend`（apps/web，vite 应用） | bin 粗分发 + 每个应用一个拼装模块（web.ts / headless.ts）；vite 应用是 `dsh-client-web` 壳表面之上的薄 main | 各应用使用动态 import，因此不会互相加载；dist 定位等 workspace 知识留在 app |
-
-#### 命名规则
-
-`packages/host/*` 与 `packages/client/*` 下的包名**必须含目录组前缀**：host/runtime → `dsh-host-runtime`、client/runtime → `dsh-client-runtime`。目录名不重复组前缀（host/ 已表达）。因此包名尾段 ≠ 目录名，tsconfig.base.json 的 `dsh-*` 通配（按目录名解析）命不中——**这两组的每包需显式 paths 条目**，且 client 各包的 `/client` 子路径要单列条目，使源码级解析与 exports map 一致。
-
-#### 怎么接入一个新应用（操作清单）
-
-1. **选 fetch 伪造方式**：浏览器同源 HTTP / 进程内 `host.handler.fetch` 注入 / 自写传输切面子类（如将来 Electron IPC，见下文「子类表」）。
-2. **在 `apps/` 下写拼装模块**：`startHost()` + 客户端子类 + 该应用私有的信号/打印/退出语义；混合体不建包，拼装写在 app 里。
-3. **需要 HTTP 承载才 import `dsh-host-webserver`**，否则零端口。
-
-现有两个应用保持这一区分：Web 应用挂载 Host、载体与浏览器组合，而 `dsh --profile headless` 挂载直接使用核心服务的 runner，不包含 Host、HTTP 或端口。ACP 类协议桥不遵循 client 载体清单：它把 core 暴露给外部生态，直接通过 `ctx.plugin(入口插件)` 挂载，不使用 fetch。
-
-## 消息协议
-
-以下各节是前置层（`dsh-host-apiproxy`）承载的协议本体。wire 上只有四种消息（四象限）——右列的 Web 承载只是示例，换载体（进程内/IPC）时四象限不变：
-
-```
-                 client 发起                      server 发起
-  request   ① ClientRequest                 ③ ServerRequest
-            （POST /api/<method> body）      （WebSocket message：session 事件、审批/问答 requested）
-  response  ② ServerResponse                ④ ClientResponse
-            （该 POST 的 HTTP 应答体）        （POST /api/respond body，回填 ③ 的 rpcId）
-```
-
-### wire 全形：四具名判别 union（`api/rpc.ts`）
-
-| 类型 | 判别 tag | 字段 | rpcId 归属 | Web 承载 |
-|---|---|---|---|---|
-| `ClientRequest` | `'client-request'` | `rpcId` `method` `payload` | client mint | `POST /api/<method>` body |
-| `ServerResponse` | `'server-response'` | `rpcId` `result` | 回填 ① | 该 POST 的应答体（恒 HTTP 200） |
-| `ServerRequest` | `'server-request'` | `rpcId` `method` `payload` | server mint | WebSocket text message |
-| `ClientResponse` | `'client-response'` | `rpcId` `result` | 回填 ③ | `POST /api/respond` body |
-
-`RpcMessage = ClientRequest | ServerResponse | ServerRequest | ClientResponse`，`switch (message.type)` 窄化。
-
-**rpcId 纪律**（`RpcId` 是 branded string，构造函数 `RpcId()`）：
-
- 谁发起谁 mint；应答一律回填对应 request 的 rpcId，**绝不 mint 新 id**。
- server-request 分两类，静态按 `method`（=帧 type）区分，**不设第三种 kind**：可应答帧（`approval/requested`、`question/requested`）的 rpcId 是稳定逻辑请求 id（受理时 mint 一次、基线回放原样复用、client 以它回填应答）；纯推送帧（`session/event` 等）的 rpcId 标识该次推送（每次新 mint）。
- 业务代码不 mint：unary 的 mint 收口在客户端基类 `callUnary`，帧的 mint 收口在 host 侧。
-
-### 签名窄形与载体补全
-
-域接口签名只感知窄形：`RpcRequest<P> = { rpcId, payload }`、`RpcResponse<T> = { rpcId, result: RpcResult<T> }`。载体层把窄形补全为全形（补 `type` tag 与 `method`），方向不靠通道推断。`RpcResult<T> = { ok: true; value } | { ok: false; error: RpcError }`——方法不 throw 业务错误。
-
-### RpcReceipt：载体回执
-
-`ClientResponse` 的 HTTP 应答体是 `RpcReceipt = { accepted: true } | { accepted: false; reason: 'not-pending' | 'bad-response' }`——载体层回执，**不是** RpcMessage（response 不再有 response）；迟到/重复应答收 `not-pending`，逻辑收敛点是 `*/resolved` 帧。
-
-## 类型体系：函数签名即真源
-
-### RpcMethodMap 与派生泛型（`api/rpc-map.ts`）
-
-方法的参数/返回结构**只住在接口方法签名里**；map 登记方法本身；其余一切位置（handler、client、store、测试）引用派生泛型，禁止复写字面量或另起平铺具名类型：
-
-```ts ignore-check
-export interface RpcMethodMap {
-  'session.list': SessionsApi['list']        // map key 即 wire 路径段
-  // …其余方法同形登记，全集见 api/rpc-map.ts
-}
-// 派生泛型（穿透窄形取业务类型；实际声明带 K extends keyof RpcMethodMap 约束）
-export type RequestPayload<K> = Parameters<RpcMethodMap[K]>[0]['payload']
-export type ResponseValue<K> =
-  Awaited<ReturnType<RpcMethodMap[K]>> extends RpcResponse<infer T> ? T : never
-```
-
-流方法（`events.mux`/`events.host`）不进 map（不是 unary）；`respond` 不进 map（是 client-response 不是方法调用）。
-
-### 错误模型（`RpcErrorDetailsMap`）
-
-错误码示例一行：
-
-| code | details | 何时 |
-|---|---|---|
-| `bad-request` | `{ issues: ZodIssue[] }` | wire/payload zod 校验失败 |
-
-码全集见 `api/rpc.ts` 的 `RpcErrorDetailsMap`。`RpcError` 是 map 展开的分布式 union：`code` 判别、`switch` 后 `details` 自动窄化；**details 必填**——新码=map 加一行+错误 schema 加一支，漏填是编译错误。transport 故障（断网、host 没起）由载体抛异常，与业务错误两层不混。
-
-### zod 双向校验与锚定
-
- **两级 parse**：全形 schema 一次（type/rpcId/method 结构 + handler 校验 path==method）→ 业务 payload 按 method/帧型分派二次 parse；拒收 = `bad-request`。
- **锚定**：schema 统一 `satisfies z.ZodType<Wire<T>>`（`api/rpc.schema.ts`）。`Wire<T>` 是深度「| undefined」宽化——仓库开 `exactOptionalPropertyTypes` 而 zod `.optional()` 输出 `T | undefined`，直接锚原类型全线不可用；JSON wire 上缺席与 undefined 同形，宽化不损失校验语义。透传宽分支（`SessionEvent`/`ContentBlock`/帧 union/`RpcError`）与 brand id schema 用显式 cast + 注释。
- brand cast 单点：每个 schema 文件的 id cast 收口一处（`rpcIdSchema` 是 rpc.schema.ts 唯一 cast 点）。
-
-## 约定面（ApiProxy）
-
-根接口 `ApiProxy = { sessions, host, events, respond }`（`api/index.ts`）。新 client-request 域 = 新的一对文件（`<域>.ts` + `<域>.schema.ts`）+ 根接口一个字段 + map 加行。
-
-### unary 方法表
-
-方法示例一行（表结构即读法）：
-
-| method key | 请求 payload | 返回 value | 语义 |
-|---|---|---|---|
-| `session.list` | `{ cursor?: string }`（cursor 留座不实现） | `{ items: SessionSummary[] }` | 已持久化 session，updatedAt 倒序；v1 不建索引 |
-
-其余方法（`session.create`/`session.history`/`session.rename`/`session.prompt`/`session.cancel`/`host.describe`）的参数与返回不在此复写——签名即真源，见 `api/sessions.ts`、`api/host.ts` 与 `RpcMethodMap`。
-
-### 帧（server→client，具名 union）
-
-两条逻辑流：mux 流（`/api/events.mux`，全 session 聚合）与 host 流（`/api/events.host`，host 级事件）。浏览器通过每流一条下行 WebSocket 消费，进程内 fetch 载体以 SSE 保持同构；物理边界见 [WebSocket 下行载体](2026-08-04-websocket-downlink-carrier.zh.md)。帧示例一行：
-
-| 帧 type | 载荷 | 何时发 |
-|---|---|---|
-| `session/event` | `{ sessionId; event: SessionEvent }` | 核心透传：core 事件原样过，`assistant/chunk` 即 token 流，无独立 delta 帧 |
-
-其余帧型不在此复写，union 全集见 `api/events.ts` 的 `MuxFrame`/`HostFrame`。语义上须知三点：`session/subscribed` 的 lastSeq 供 history 竞态检测；`approval/question` 的 requested 帧可应答（rpcId 稳定）、resolved 帧是收敛面；`host/agent-error` 是无 turn 位置 live 失败的唯一出口。
-
-**透传纪律**：wire 上的事件/消息/内容块就是 core 类型（`SessionEvent`/`ContentBlock`），不造第二套 DTO；类型经 `import type` 依赖链直达浏览器。`SessionEventMap` merge-extensible：client 对未知 type documented-default（忽略），事件 schema 留「合法信封+未知类型」分支——信封仍严格，不是字段级 passthrough。
-
-### 会话语义（impl 侧承诺）
-
- **历史 = 事件回放**：一套 fold（client 侧），历史分页与 live 增量同一条代码路径；server 不做物化快照第二套。history **页边界对齐消息边界**（绝不从消息中间截断；分片随定稿消息归组），尾页含进行中 partial 的分片。
- **提示词关联**：提示词的 rpcId 经 MessageSource（`'user-rpc'`）透传进 `user/message` 事件，client 以此把乐观回显转正。
- **重连 = 重建**：不做续传 cursor（`mux` 的 `since` 签名留座、传了忽略）；断线重开流 + 重拉 history；`subscribed.lastSeq` 与 history 尾 seq 比对，有缝再补拉一次。
- **冷会话处理遵循所有权**：`session.history` 与 `session.fork` 的源端读取会在不获取 Agent 的情况下检查持久化存储，而绑定到 Agent 的普通会话方法（如 `prompt`）则通过在途表去重后恢复会话。由会话支撑的 subagent 会拒绝这条通用恢复路径，且附加状态不对客户端暴露（`running` 已经覆盖）。
- **审批/问答**：requested 帧受理时 mint 稳定 rpcId；先到先赢，host 内存 pending 表（keyed by rpcId）是唯一裁判；mux 重开后在 subscribed 帧后回放仍 pending 的 requested 帧（rpcId 原样复用，刷新恢复）。审计事件 `approval/asked`/`decided` 照旧走 durable 日志——帧=live 控制面，事件=durable 审计。**现状**：约定与帧类型已 shipped，host 侧 pending 表/wire answerer 未实现（`api-proxy.ts` 的 `respond` 是 stub，恒回 `not-pending`）；PendingCard v1 只展示。
- **不设协议版本**：client 与 host 绑定发布，`host.describe` 无 protocolVersion 字段；出现独立发布的 client 时再引入。
- **预留方法纪律**：map 只含已实现方法，未知 method 在信封 parse 即 fail loud（`bad-request`），不设 not-implemented 兜底码。预留清单（实现时把签名抄进域接口+map 加行+schema 加对即升格）：`session.fork`、`prompt.mode` 加 `'inject'`、`task.list`、`host.listModels`、describe 加 `hostInstanceId`。（`session.rename` 已从本清单毕业：追加 user 来源的 `session/title` 事件。）
-
-## 客户端载体：AbstractApiClient 类体系（`fetch/client.ts`）
-
-**协议不变量住基类，平台差异是两个切面**：抽象方法 `doFetch(url, init)`（传输）+ 可覆写 `onEnvelope`（观测）。
-
-### IApiClient：caller 视图
-
-与 `ApiProxy` 同域树，但 unary 方法**收业务 payload 直传**——载体 mint rpcId 并包信封，业务代码永不 mint；需要本次调用 rpcId 的从返回的 `RpcResponse` 回显里读。`ApiProxy` 是 impl 侧实现的窄形签名约定，`IApiClient` 是 client 侧消费的 payload 直传视图，`AbstractApiClient` 桥接两者。方法逐 key 从 `RpcMethodMap` 派生——map 加行即机械更新。
-
-### 基类持有的协议路径
-
-| 路径 | 内容 |
-|---|---|
-| `callUnary` | mint → tap → POST 全形 → `serverResponseSchema` parse → **rpcId 回显校验**（不符即 throw）→ tap → 吐窄形 |
-| `readSse` | streaming fetch（非 EventSource）、`\n\n` 分帧、`data:` 拼接、ServerRequest 全形 parse、tap、吐窄形 `RpcRequest<帧>` |
-| `respond` | client-response 透传（rpcId 是回填，此处不 mint）；应答体 `rpcReceiptSchema` parse |
-| unary 时限 | 普通 unary 调用使用 `AbortSignal.timeout`（默认 30s，构造参数可调）；由用户掌控节奏的 `host.pickDirectory` 和 `command.execute` 不设该时限，但保留调用方／连接取消；流不设时限 |
-| `resolveBase` | 浏览器=同源 origin；无 location 环境（Node）=`http://dsh.internal` 假 authority |
-
-### 实例级 envelope 观测切面
-
-四象限全形均过 `onEnvelope`；基类实现是**实例持有的微任务合批缓冲**（帧风暴不逐帧惊扰消费方；模块级状态会跨实例/测试泄漏，故实例持有）。观测者经 `subscribeEnvelopes(listener)` 订阅（收整批 `readonly RpcMessage[]`，返回退订函数）；listener 抛异常被隔离（观测不得反噬载体）。无订阅者时零缓冲成本。没有任何已交付消费方订阅——该切面是 wire 诊断的预留位（已退役的 RPC 调试面板是它的首个消费方，将来的诊断消费方接入时不动载体）。
-
-### 子类表（传输承载）
-
-| 子类 | 所在包 | doFetch | 用途 |
-|---|---|---|---|
-| `InProcessApiClient` | apiproxy 本包 | 注入的 `{ fetch }` handler | **同构点**：`new InProcessApiClient(toFetchHandler(api))` 全程不过网络但真跑 wire 序列化/zod/SSE 帧；载体测试与调用方可以在不打开端口的情况下运行这套协议，而产品 `dsh --profile headless` 直接驱动 core |
-| `WebApiClient` | dsh-client-connection | `globalThis.fetch` 上行 + 每逻辑流一条同源 WebSocket 下行 | 浏览器客户端；物理边界见 [WebSocket 下行载体](2026-08-04-websocket-downlink-carrier.zh.md) |
-| `FixtureApiClient` | dsh-client-connection | 不用（协议层覆写） | 无 server 的 UI 开发（`?fixture`）：覆写 `callUnary`/`openMux`/`openHost`/`respond` 虚方法，自己就是假 server（帧 rpcId 由它 mint，语义自洽） |
-| IPC 桥子类（假想示例——尚无此形态） | Electron 壳 | IPC 序列化往返 | 只需换 doFetch，约定/基类零改 |
-
-## 怎么扩展（操作清单）
-
-**加一个 unary 方法（5 步）**：①域接口加方法签名（参数/返回内联，这是唯一真源）；②`RpcMethodMap` 加一行；③`<域>.schema.ts` 加 request/value schema 对（锚 `Wire<RequestPayload<'…'>>`）；④handler `UNARY_ROUTES` 加一行（handler 的 Web 承载见 Web 客户端架构笔记）；⑤impl 实现（回显 `request.rpcId`）。client 侧 `IApiClient`/`AbstractApiClient` 的域方法表同步加一行透传。
-
-**加一个帧型（3 步）**：①`MuxFrame`/`HostFrame` union 加一支（可应答帧须注明 rpcId 稳定语义）；②帧 schema 加一支；③消费方的 fold/路由 documented-default 已兜底未知型，按需加显式分支。
-
-**加一个错误码（2 步）**：①`RpcErrorDetailsMap` 加一行（details 必填）；②`rpcErrorSchema` discriminatedUnion 加一支。
-
-**接一种新载体**：继承 `AbstractApiClient` 只实现 `doFetch`；需要拦截协议层（如 fixture（测试前置数据））再覆写 `callUnary`/`openMux`/`openHost` 虚方法。约定与基类零改。
-
-**升格一个预留方法**：把预留签名抄进域接口 → map 加行 → schema 加对 → UNARY_ROUTES 加行 → impl 实现。
-
-## Consequences
-
-所有 client 使用同一约定：加一个 unary 方法是从单一签名出发的五步机械改动，换载体只动一个 `doFetch` 子类，wire 上每条消息可 zod 校验、可经 envelope tap 观测、可按 rpcId 对账。普通 unary 调用仍受时限约束，而 `host.pickDirectory` 与 `command.execute` 可保持挂起，直到操作完成或调用方／连接取消到来；若由用户掌控节奏的操作不自行结束，请求可能一直挂起，这是为避免把合理的操作时长视为传输失败而接受的代价。其余接受的代价：两组包需要显式 tsconfig paths 条目；预留方法（fork/inject/task.list/listModels/hostInstanceId）在真实消费方出现前保持休眠。
-
-## Alternatives considered
-
-| 放弃项 | 一句话理由 |
-|---|---|
-| 按产品分包（web 一族、electron 一族） | 产品共享的是 host/client 两侧能力，而不是某个应用实现；能力提供方分层让新应用零新包 |
-| 混合体建包（如 headless 独立包） | 混合体只有一个消费方（它自己的 app），建包是无主抽象；拼装写在 app 里可读可弃 |
-| 消费型 client 直连 ctx（省 apiproxy 一层） | client 需要 wire 校验、观测与多 client 一致性。直接 headless 是没有 client 边界的本地入口，使用公开的 Agent／Session seam，而不是 client 命令面 |
-| webserver 依赖 runtime（省 handler 注入） | 结构 typing 注入让 webserver 可被 sidecar/测试复用且零 workspace 依赖；包依赖会把装配知识拖进承载层 |
-| 包名不带组前缀（沿用 dsh-<尾段>） | `dsh-runtime`/`dsh-web-ui` 在扁平 npm 命名空间里失去归属信息；代价只是每包一条显式 paths |
-| 复用仓内 JSON-RPC 2.0（dsh-sdk-jsonrpc-server） | 数字错误码退化成单码兜底、约定双份人肉对齐、命名无 convention 自然漂移 |
-| 三信封模型（Request/Response/Frame 各一信封，签名不感知方向） | rpcId 是逻辑层关联，帧与应答的方向语义靠通道推断在换载体时即失效 |
-| 具名 Request/Response 类型对为真源（map 登记类型对） | 平铺具名类型是同一事实的第二个名字；签名 infer 反推让加方法只改一处 |
-| REST 风格路径 | 消费方是自家 client，无第三方 REST 体验诉求；RPC 直映方法表更机械 |
-| DTO 层（wire 专用第二套结构） | core 类型 type-only 直达浏览器零成本；DTO 是永久的双向同步税 |
-| cursor 续传（mux since 实装） | 重连=重建（opencode 同款）覆盖 v1 全部需求；签名留座，实装等真实消费方 |
-| createApiClient 工厂函数（原实现） | 平台差异（传输/观测）是继承切面不是参数；类体系让 fixture 在协议层替换而不是包一层假信封 |
-| 对 `command.execute` 应用 30 秒传输时限 | 命令耗时属于操作本身，而非传输健康预算；该时限会终止本应继续运行的长时处理器，调用方／连接取消已提供所需的停止路径 |

-## Problem
-
-Cordis plugins can register human commands through `ctx.commands`, but a command that needs terminal interaction has no supported presentation boundary. It must either remain non-interactive or capture the TUI's private pi-tui tree, focus state, renderer, and shutdown lifecycle. That coupling makes the extension depend on one front door's internals, lets independently developed overlays compete for focus, and leaves plugin unload with no reliable way to remove queued or visible UI.
-
-## Decision
-
-A mounted `@deepseek-ai/dsh-tui` provides `ctx.tui` after terminal startup succeeds. The service belongs to that exact terminal and agent, disappears before terminal teardown, and causes plugins that inject it to unload and reload with provider availability. Other front doors do not emulate it.
-
-`ctx.tui.openOverlay()` is the first and only interactive extension primitive. It accepts a component factory, constrained layout options, and an optional abort signal. The factory receives a frozen host with the current viewport, semantic theme functions, display-text escaping, redraw, close, and a lifetime signal. It does not receive the pi-tui `TUI`, overlay handle, editor, transcript tree, focus controller, or terminal object.
-
-One private overlay manager serializes built-in and plugin requests in FIFO order. The model selector and `ctx.userInteraction` question panel use the same manager, so all modal interaction has one focus owner. Closing the active overlay restores pi-tui's previous focus before the next request activates. Overlay state is process-local presentation: it is neither appended to the session log nor rebuilt during resume.
-
-The service method runs through Cordis's traceable service proxy. It installs an effect on the calling plugin fiber before admitting the request; caller disposal therefore removes a queued request or closes an active overlay and awaits the same settled outcome. TUI shutdown first rejects admission, then disposes the service fiber so dependent plugins and their effects quiesce, settles remaining built-in work, and only then drains and stops the terminal.
-
-Component construction, rendering, input, and invalidation run behind an exception boundary. A failure closes that request with an `error` outcome, reports a visible terminal error, and lets the queue continue. Components are trusted package code: their rendered lines may contain ANSI styling, and they must call `host.display()` before including untrusted text.
-
-## Verification
-
-Manager tests pin FIFO admission, cancellation, repeated close, shutdown outcomes, guarded callbacks, host capabilities, and per-file coverage. Cordis lifecycle tests pin caller ownership, provider loss and return, unloading-time rejection, and cleanup quiescence. Fake-terminal integration tests exercise plugin overlays alongside built-in questions, restored editor input, terminal remount, startup rollback, and service disappearance. Existing TUI interaction tests continue to exercise the model selector and question panel through the shared path.
-
-## Alternatives considered
-
-**Expose pi-tui objects directly.** This gives plugins maximum freedom but makes private focus, rendering, and teardown state a public compatibility contract. It also cannot arbitrate independently loaded overlays.
-
-**Put interactive callbacks on command definitions.** Commands remain transport-neutral domain entries even though TUI is their only shipped consumer. Adding terminal state to `ctx.commands` would couple discovery and dispatch to one presentation implementation.
-
-**Create a complete TUI slot and action framework at once.** Actions, editor replacement, transcript renderers, status regions, and completion providers have different composition and conflict rules. Shipping them behind one broad API would freeze those rules before a concrete consumer proves them.
-
-**Persist open overlays in session events.** Modal presentation is not model-visible session state, and arbitrary component state is not replayable. The plugin that owns durable data records that data through its domain service and recreates presentation when appropriate.
-
-## Consequences
-
-Interactive plugins gain a small stable front door with deterministic focus and Cordis-owned cleanup, while the TUI keeps authority over terminal lifecycle and pi-tui internals. Built-in dialogs and extensions cannot overlap or strand focus.
-
-The API deliberately covers modal overlays only. Human command registration remains on `ctx.commands`; actions, slots, editor replacement, event renderers, and completion providers require separate contracts when real consumers establish their ordering and ownership semantics. FIFO serialization also means one stalled overlay blocks later modal work until its owner closes, aborts, or unloads it.

-## 问题
-
-Cordis 插件可以通过 `ctx.commands` 注册用户命令，但需要终端交互的命令没有受支持的呈现边界。它只能保持非交互，或者捕获 TUI 私有的 pi-tui 树、焦点状态、渲染器和关闭生命周期。此类耦合会使扩展依赖某个入口的内部实现，让各自独立开发的浮层争抢焦点，并导致插件卸载时无法可靠移除排队中或已显示的 UI。
-
-## 决策
-
-挂载的 `@deepseek-ai/dsh-tui` 在终端成功启动后提供 `ctx.tui`。该服务只属于挂载时绑定的终端与 agent（智能体），在终端拆卸前消失，并使注入它的插件随着提供方的可用与否卸载和重新加载。其他入口不会模拟该服务。
-
-`ctx.tui.openOverlay()` 是第一个也是唯一一个交互扩展原语。它接受组件工厂、受限的布局选项，以及可选的中止信号。工厂收到一个冻结的 host，其中包含当前视口、语义化主题函数、显示文本转义、重绘、关闭和生命周期信号。它不会收到 pi-tui `TUI`、浮层句柄、编辑器、transcript（文本记录）树、焦点控制器或终端对象。
-
-一个私有浮层管理器按 FIFO 顺序串行处理内置请求和插件请求。模型选择器与 `ctx.userInteraction` 问题面板使用同一个管理器，因此所有模态交互只有一个焦点所有者。关闭活动浮层时，系统会先恢复 pi-tui 之前的焦点，再激活下一项请求。浮层状态是进程本地的呈现状态：它既不会追加到会话日志，也不会在恢复期间重建。
-
-服务方法通过 Cordis 的可追踪服务代理运行。它在接纳请求前，向调用方插件的 fiber 注册一个 effect；因此，调用方执行 dispose（资源释放）时会移除排队中的请求或关闭活动浮层，并等待同一个结果完成结算。TUI 关闭时会先拒绝新请求，再 dispose 服务 fiber，让依赖插件及其 effect 完全静止，然后结算其余内置工作，最后才排空并停止终端。
-
-组件构造、渲染、输入与失效处理均在异常边界内运行。任何失败都会以 `error` 结果关闭对应请求、在终端中报告一条可见错误，并让队列继续处理。组件属于受信任的包代码：其渲染行可以包含 ANSI 样式，但加入不受信任的文本前必须调用 `host.display()`。
-
-## 验证
-
-管理器测试固定了 FIFO 准入、取消、重复关闭、关闭结果、受保护回调、host 能力和逐文件覆盖率。Cordis 生命周期测试固定了调用方所有权、提供方消失与恢复、卸载期间的拒绝，以及清理达到完全静止。模拟终端集成测试覆盖插件浮层与内置问题的协作、编辑器输入焦点恢复、终端重新挂载、启动回滚和服务消失。既有 TUI 交互测试继续通过共享路径覆盖模型选择器与问题面板。
-
-## 考虑过的替代方案
-
-**直接暴露 pi-tui 对象。** 这会赋予插件最大的自由度，却会把私有的焦点、渲染与拆卸状态变成公开兼容性契约，也无法在独立加载的浮层之间进行仲裁。
-
-**在命令定义中加入交互回调。** 命令仍是传输无关的领域条目，尽管 TUI 是唯一已交付的消费方。向 `ctx.commands` 添加终端状态，会让发现与分派流程耦合到某一种呈现实现。
-
-**一次性建立完整的 TUI slot 与 action 框架。** action、编辑器替换、transcript 渲染器、状态区域和补全提供方具有不同的组合规则与冲突规则。在具体消费方验证这些规则之前就将其纳入一个宽泛 API，会过早固化这些规则。
-
-**将打开的浮层持久化为会话事件。** 模态呈现并非模型可见的会话状态，任意组件状态也无法回放。拥有持久数据的插件应通过自身的领域服务记录这些数据，并在适当时重新创建呈现。
-
-## 后果
-
-交互式插件获得一个小而稳定的入口，具备确定性的焦点管理和由 Cordis 持有的清理机制；TUI 则继续掌控终端生命周期和 pi-tui 内部实现。内置对话框与扩展无法重叠，也不会遗留失去归属的焦点。
-
-该 API 有意只覆盖模态浮层。用户命令仍然在 `ctx.commands` 上注册；action、slot、编辑器替换、事件渲染器和补全提供方需要另行设计契约，等待实际消费方确定其顺序与所有权语义。FIFO 串行处理也意味着，一个停滞的浮层会阻塞后续模态工作，直至其所有者关闭、中止或卸载该浮层。

-## Problem
-
-Exact reads, semantic filters, relationship traces, and full-text search operate on the same live-preferred session corpus. Exposing full-text search under a second context key makes consumers and app compositions treat one capability as two services, even though the SQLite implementation is the only backend-specific part.
-
-The interface package already owns the shared record, filter, trace, search-request, cursor, and error contracts. A provider registry or coordinator would add runtime selection semantics unsupported by any current consumer.
-
-## Decision
-
-`SessionQueryService` is the single abstract service registered as `ctx.sessionQuery`. It concretely implements listing, title and event reads, surface reads, filtering, and relationship tracing through its backend-independent `SessionCorpus`. Its only abstract methods are `searchSessions()` and `searchEvents()`.
-
-`SessionQuerySqlite` extends that service and is the sole concrete backend. One mounted instance therefore exposes every operation through `ctx.sessionQuery`; its inherited exact operations use the shared corpus implementation, while its SQLite-owned lifecycle observes sources, reconciles the derived FTS index, ranks matches, and owns cursor generations. The interface package has no standalone concrete plugin, search-provider registry, or second context key.
-
-SQLite reconciliation is one quiescent serialized state machine. It passes the caller's exact abort signal into durable snapshot listing and inspection, awaits each started backend operation itself, and checks cancellation after every await and before starting the next source or index operation. Cancellation therefore cannot release the serializer while an ignored or cooperative backend call is still cleaning up, and it cannot start a subsequent listing, inspection, reconciliation, or query after the signal is observed.
-
-Backend configuration includes the inherited `readWindowMax` setting alongside its own index path, journal mode, page limits, and snippet limit. First-party apps that need session queries mount the SQLite backend and place its disposable index beside their configured persistence root.
-
-This service topology supersedes the separate-key portion of the [exact query decision](../feature/2026-07-10-session-query-service.md) and [SQLite search decision](../feature/2026-07-10-sqlite-session-query-provider.md); their corpus, query, tokenizer, reconciliation, and safety decisions remain in force.
-
-## Alternatives considered
-
- **Keep `ctx.sessionQuery` and `ctx.sessionSearch` separate** — rejected because both expose operations over one logical corpus, force consumers to discover two keys, and let apps accidentally mount only a partial query surface.
- **Keep a concrete base service and let the SQLite plugin register or mutate two search methods** — rejected because method availability would depend on plugin order and teardown, and the service would need a provider registration protocol for one implementation.
- **Move every query implementation into the SQLite package** — rejected because exact reads, filters, and traces require no index and are shared behavior that belongs with their provider-independent contracts.
-
-## Consequences
-
-Consumers inject one service and can combine exact and full-text operations without a second capability lookup. A production composition must choose a concrete backend even when one consumer currently calls only inherited exact methods; tests may use a minimal subclass when backend behavior is outside their scope.
-
-The unified object deliberately retains two internal observation strategies: exact operations read authoritative live/persisted sources per call, while full-text operations reconcile a disposable index. Sharing the context key does not make the derived index authoritative or couple exact-read availability to an FTS query.
-
-Queued cancellation remains prompt. Cancellation during active asynchronous source observation waits for that started operation to settle, which makes rejection a quiescence boundary and preserves single-file execution for a following search. Synchronous SQLite statements remain non-preemptible and are bracketed by signal checks.
-
-Unit coverage pins inherited and abstract behavior on one key, SQLite coverage exercises both operation families on the concrete backend, and the real Loader path verifies that one exported plugin registers the combined service.

-# Agent Note: 统一会话查询服务

-Status: implemented

-[English](2026-07-23-unified-session-query-service.md) | 中文
-
-## 问题
-
-精确读取、语义过滤、关系追踪与全文搜索都作用于同一个实时源优先的会话语料库。将全文搜索暴露在第二个上下文键下，会让消费方与应用组合把同一项查询功能视为两个服务，尽管只有 SQLite 实现是后端特有的部分。
-
-接口包已经拥有共享的记录、过滤、追踪、搜索请求、游标与错误契约。提供方注册表或协调器会引入运行时选择语义，而目前没有任何消费方支持这种语义。
-
-## 决策
-
-`SessionQueryService` 是注册为 `ctx.sessionQuery` 的唯一抽象服务。它通过后端无关的 `SessionCorpus` 具体实现列表查询、标题与事件读取、表层读取、过滤和关系追踪。仅有 `searchSessions()` 与 `searchEvents()` 两个方法为抽象方法。
-
-`SessionQuerySqlite` 扩展该服务，并且是唯一的具体后端。因此，一个挂载实例便可通过 `ctx.sessionQuery` 暴露全部操作；其继承的精确操作使用共享的语料库实现，而由 SQLite 管理的生命周期负责观察数据源、对齐派生 FTS 索引、对匹配项排序并管理游标代际。接口包不提供独立的具体插件、搜索提供方注册表或第二个上下文键。
-
-SQLite 的对齐过程是一个具备静止性保证的串行状态机。它将调用方的原始中止信号传给持久化快照列表与检查操作，直接等待每个已经启动的后端操作，并在每次等待后以及启动下一个数据源或索引操作前检查是否已取消。因此，即使后端忽略取消或正在配合清理，串行器也不会提前释放；观察到中止信号后，也不会再启动后续的列表、检查、对齐或查询操作。
-
-后端配置除了自身的索引路径、日志模式、分页限制与文本片段长度上限外，还包含继承的 `readWindowMax` 设置。需要会话查询的第一方应用挂载 SQLite 后端，并将其可丢弃索引放在已配置的持久化根目录旁。
-
-这一服务拓扑取代了[精确查询决策](../feature/2026-07-10-session-query-service.md)和 [SQLite 搜索决策](../feature/2026-07-10-sqlite-session-query-provider.md)中关于分离上下文键的部分；其中关于语料库、查询、分词器、对齐与安全性的决策仍然有效。
-
-## 已考虑的替代方案
-
- **保留相互独立的 `ctx.sessionQuery` 与 `ctx.sessionSearch`**：不予采纳，因为二者都针对同一逻辑语料库提供操作，迫使消费方识别两个键，还可能让应用误挂载一组不完整的查询接口。
- **保留具体的基础服务，再由 SQLite 插件注册或修改两个搜索方法**：不予采纳，因为方法是否可用将取决于插件顺序与资源释放时机，而且该服务需要为唯一的实现定义一套提供方注册协议。
- **将所有查询实现移入 SQLite 包**：不予采纳，因为精确读取、过滤与追踪不需要索引，并且都属于应与提供方无关契约放在一起的共享行为。
-
-## 后果
-
-消费方只需注入一个服务，无需再次查找其他功能，便可组合精确操作与全文操作。生产环境的组合必须选择一个具体后端，即使当前某个消费方只调用继承的精确方法；如果后端行为不在测试范围内，测试可以使用最小子类。
-
-统一后的对象有意保留两种内部观察策略：精确操作在每次调用时读取权威的实时源或持久化源，全文操作则使可丢弃索引与数据源对齐。共用上下文键不会让派生索引成为权威来源，也不会使精确读取的可用性依赖 FTS 查询。
-
-排队阶段的取消仍会及时生效。在异步数据源观察已经开始后取消时，调用方会等待该操作完成清理后才收到拒绝；因此拒绝本身构成静止边界，并保证后续搜索仍按单一串行流程执行。同步 SQLite 语句无法在执行中被抢占，服务会在其前后检查中止信号。
-
-单元测试在同一个键上同时固定继承实现与抽象方法的契约，SQLite 测试在具体后端上覆盖两类操作，真实 Loader 路径则验证单个导出的插件能够注册组合后的服务。

-# Agent Note: Parse `dsh` argv through one Commander adapter
-
-Status: implemented
-Archived: 2026-07-26
-
-English | [中文](2026-07-24-dsh-commander-argument-adapter.zh.md)
-
-## Problem
-
-The `dsh` CLI entry (`apps/cli`) parsed argv in three hand-rolled idioms that did not compose and gave no `--help`/`--version`. `bin.ts` dispatched by raw inspection — `argv[0] === 'web'`, then `argv.includes('-p') || argv.includes('--prompt')`, else TUI — which is positional-blind: a prompt flag or a config path in the wrong position could misroute the mode, and `argv.includes('-p')` could not tell a real flag from an incidental token. `headless.ts` and `web.ts` each ran their own `node:util` `parseArgs` with inline host/port validation, and `dsh-app-boot` carried `parseResumeArg`, a ~30-line bespoke scanner reimplementing flag/`=`-form/value/repeat handling for `--resume`. Usage was a single hardcoded `usage: dsh -p "task"` line; there was no version flag and no rendered help.
-
-## Decision
-
-Argv is parsed once, in `apps/cli/src/args.ts`, through a Commander adapter (the same parser the SDK bins — `create-sdk`, `dsh-scripts` — already standardize on). `parseDshArgs(argv, version)` returns a discriminated `DshInvocation` union of the three real modes: `{ mode: 'tui', config?, resume? }`, `{ mode: 'headless', prompt }`, or `{ mode: 'web', host?, port?, dev }`. It does **not** model help/version/errors as data: Commander owns those, printing usage or the diagnostic and exiting at the point of failure. `exitOverride()` turns each into a thrown `CommanderError` carrying the intended code (0 for help/version, 1 for a parse or domain error), which one `try/catch` in `parseDshArgs` turns into `process.exit`.
-
-`bin.ts` calls the adapter once and switches on `mode` (closed union, `satisfies never` default), dynamic-importing only the chosen mode's module; only a valid, non-help invocation reaches the switch, so it has no help/version/error cases. Each mode module consumes already-parsed values: `runTui(config, resume)`, `runHeadless(task)`, `runWeb(host, port, dev, workspaceRoot)` — none re-reads argv. It is **one Commander program**: the default surface (no subcommand) carries option-only flags — `--config <path>`, `-p/--prompt <task>`, `--resume <id>` — and `web` is a real `program.command('web')` subcommand. The default surface takes no positional argument, which is what lets `web` be a real subcommand without a positional collision, so `dsh --help` lists `web` natively (no hand-pasted command text). The default action and the `web` action set the resolved mode, then bail via `command.error(...)` (print + exit 1) on the domain checks Commander cannot express: `--prompt` selects headless and rejects an empty task or a `--config`/`--resume` alongside it rather than silently dropping a TUI input; an empty `--resume=` id fails loud (agent-loop treats `''` as no-resume). Commander parses the default-surface options on either side of the `web` token into `program.opts()`; since `web` shares none of them, the `web` action rejects a leaked `--config`/`-p`/`--resume` (`dsh web -p x`, `dsh --config c.yml web`) rather than silently serving and dropping it. `dsh web`'s `--host`/`--port` are unvalidated pass-through overrides: the adapter assigns no default and does no validation, only `Number`-coercing the port string (the schema wants a number). The `dsh-host-webserver` schemastery `Config` (`host` a `127.0.0.1`/`0.0.0.0` literal union, `port` a natural ≤ 65535) is the single source of both the default (the shipped `apps/cli/cordis.yml` `webserver` row stands when a flag is absent) and validity — `AppCLIEntry` patches an explicit flag straight into that row, so a bad host/port fails loud at the schema on boot, not at parse. `--dev` mounts the client HMR driver and bundle watch, and `--workspace-root <path>` is a plain pass-through to `AppCLIEntry` (the parent directory for name-created workspaces). A repeated `--resume`, or a following flag captured as a `--resume`/`--prompt` value, is Commander's standard behavior (last-wins / next-token) and is left alone; a bad id fails loud downstream when the session cannot load. `--version` reads this app's `package.json`.
-
-`dsh` takes no positional argument. `--config <path>` names an alternate cordis tree to boot instead of the shipped default; it exists only so the demo/test call sites (`demo:cordis`, `demo:code-mode`, the keyless PTY smokes) can point the shipped bin at an example tree. A bare `dsh` boots the shipped tree plus the `~/.dsh/config.yaml` personal overlay; a real user never passes `--config`.
-
-CLI parsing lives entirely in `apps/cli`. `dsh-app-boot` holds the boot/env/config/personal-overlay helpers and no argv scanner.
-
-## Session resume through the boot context
-
-`dsh --resume <id>` is the one way to resume a persisted session, with no environment variable. `runTui` provides the parsed id on the boot context through `boot`'s `prepare(ctx)` hook — `ctx.provide(RESUME_SESSION_ID_KEY, id)` (a `dsh-app-boot` export, value `'resumeSessionId'`) — and the shipped tui-agent/cordis configs read it as a bare identifier: `resumeSessionId: !!js "typeof resumeSessionId === 'string' ? resumeSessionId : undefined"`. The expression is quoted because YAML otherwise parses the `?`/`:` as a mapping; the `typeof` guard tolerates a launcher that never provides the slot. The `/resume` in-place handoff (`process.execve`) rebuilds its re-exec argv from the parsed values as `dsh --resume=<id> [--config <path>]`.
-
-## One terminal front door: `dsh`
-
-`dsh` is the only terminal entry point; the `dsh-tui-demo` package ships the TUI app bundle plugin the shipped config mounts, and no bin of its own. `demo:cordis`, `demo:code-mode`, and both the tui-agent and cordis-agent keyless PTY smokes launch through `apps/cli/src/bin.ts` with `--config <path>`. `dsh`'s TTY guard (refuse piped stdio before booting, pointing at `dsh -p` for automation) is pinned by `apps/cli/tests/built-bin.e2e.ts`, which runs the built `lib/bin.js` under plain Node with piped stdio (`apps/cli/tests` is in the e2e vitest include). `cli-demo`, `acp-demo`, and `jsonrpc-demo` keep their own bins because each is a distinct surface (headless, ACP, JSON-RPC) `dsh` does not provide.
-
-## Package topology
-
-The argument surface stays inside `apps/cli`, the assembly tier, not a `packages/*` library: it is this one app's routing, not a reusable seam. `dsh-app-boot` shrinks to boot glue with no CLI-parsing responsibility. `commander@^15` is added to `apps/cli/package.json`, matching the SDK bins' pin.
-
-## Alternatives considered
-
-**Keep `node:util` `parseArgs` and only unify the dispatch** — rejected: `parseArgs` has no subcommand model, no rendered help, and no version flag, so `web` routing and `--help`/`--version` would stay hand-rolled. The repo already chose Commander for its other CLIs; a second parser idiom for `dsh` alone is the fragmentation this change removes.
-
-**Keep `parseResumeArg` as a shared helper and feed it Commander's residual args** — rejected: the whole point is to retire the bespoke scanner. Commander parses `--resume` (space and `=` forms, missing-value, position-independence) natively; keeping a parallel hand-written path for the one flag would preserve the duplication the change exists to end.
-
-**A bare `dsh <config>` positional for the alternate tree** — rejected: a root positional and a real `web` subcommand cannot coexist in one Commander program (the subcommand claims the first positional). A positional would force `web` into a reserved-first-token dispatch to a separate parser and a hand-maintained `web` line in `--help`. Only the demo/test sites ever need to name an alternate tree, so a `--config` flag serves them while leaving the default surface positional-free — `web` is then a normal subcommand in one program with native `--help`.
-
-**Make the argument surface a `packages/*` seam** — rejected: nothing outside `dsh` consumes it, and capability seams are not split preemptively. The Commander adapter is `apps/cli`'s own concern.
-
-**Keep `RESUME_SESSION_ID` as the resume bridge** — rejected: with `--resume` parsed into a value the bin already holds, threading it through an environment variable the config re-reads is indirection with no benefit, and it left the demo bin a second, env-only resume path. Providing the id on the boot context is the same channel `boot`'s `prepare` hook already uses for `tuiResumeHost`.
-
-**Keep the `dsh-tui-demo` bin** — rejected: it duplicated `dsh --config <path>` exactly, and keeping it forced the demo-only `RESUME_SESSION_ID` fallback to stay alive. Its plugin is what the configs actually mount; only the front-door bin was redundant, and `dsh` is the one terminal entry point.
-
-## Testing
-
-`apps/cli/tests/args.spec.ts` (new; `apps/*/tests` added to the vitest include and `apps/cli/tests` to `tsconfig.host.json`) covers the adapter at the level that matters: mode routing by shape (including `web --dev` and the host/port pass-through), the exit-code behavior for the adapter's fail-loud checks (empty resume/prompt, `--prompt` mixed with a config/`--resume`, unknown option, stray positional), and `--help`/`--version`, captured through a `process.exit` spy. Host/port validity is the webserver schema's job, exercised on boot by the web smoke, not the adapter spec. Both PTY smoke groups in `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` now drive the real `apps/cli/src/bin.ts`: the `tui-agent` group boots an example tree through `--config`, and the `dsh CLI` group covers default boot, personal overlay, invalid config, the `--resume` config intake, the `process.execve` in-place resume handoff, and the source-path prompt. `examples/cordis-agent/tests/keyless-smoke.e2e.ts` likewise launches through `dsh`. `packages/ui/app-boot/tests/app-boot.spec.ts` drops its `parseResumeArg`/`replaceResumeArg` blocks; the TUI unit and snapshot fixtures use the `dsh --resume {session}` resume command.
-
-## Consequences
-
-`dsh` has rendered `--help`/`--version` and consistent fail-loud parse errors, and mode routing does not depend on flag position. Argv parsing lives in one place with one parser idiom shared with the SDK bins, at the cost of a `commander` dependency on `apps/cli` and Commander's parse semantics (its error strings, its `exitOverride` contract) sitting on the CLI's front door. `dsh-app-boot` owns no CLI-parsing surface; a consumer needing `--resume`-style parsing composes Commander. Session resume rides the boot context rather than an environment variable, and `dsh` is the single terminal front door — the `dsh-tui-demo` package is a plugin bundle a config mounts.

-## 问题
-
-`dsh` 的 CLI（命令行界面）入口（`apps/cli`）以三种手写方式解析 argv，这些方式无法组合，也不提供 `--help`/`--version`。`bin.ts` 通过原始检查进行分发：先判断 `argv[0] === 'web'`，再判断 `argv.includes('-p') || argv.includes('--prompt')`，否则走 TUI。这种方式对位置不敏感：位置错误的 prompt 标志或配置路径可能把模式路由错，而 `argv.includes('-p')` 无法区分真正的标志和偶然出现的 token。`headless.ts` 和 `web.ts` 各自运行自己的 `node:util` `parseArgs`，并内联校验 host/port，而 `dsh-app-boot` 携带 `parseResumeArg`——一个约 30 行的定制扫描器，为 `--resume` 重新实现了标志、`=` 形式、取值和重复的处理。用法说明只有一行硬编码的 `usage: dsh -p "task"`；既没有版本标志，也没有渲染出的帮助信息。
-
-## 决策
-
-argv 只在 `apps/cli/src/args.ts` 中解析一次，并使用 Commander 适配器（SDK bin `create-sdk`、`dsh-scripts` 已经统一采用的同一解析器）。`parseDshArgs(argv, version)` 返回仅包含三种实际模式的判别式 `DshInvocation` 联合类型：`{ mode: 'tui', config?, resume? }`、`{ mode: 'headless', prompt }` 或 `{ mode: 'web', host?, port?, dev }`。它**不会**将帮助、版本信息或错误建模为数据：这些情况由 Commander 处理，在触发处打印用法或诊断信息并退出。`exitOverride()` 会将每种情况转为抛出的 `CommanderError`，并携带预期退出码（帮助或版本为 0，解析错误或领域错误为 1）；唯一一处 `try/catch` 位于 `parseDshArgs` 中，捕获错误后调用 `process.exit`。
-
-`bin.ts` 只调用适配器一次，并对 `mode` 做分支切换（封闭联合类型，默认分支为 `satisfies never`），仅动态导入所选模式对应的模块；只有合法的非帮助请求才会进入这段分支逻辑，因此其中没有帮助、版本或错误分支。每个模式模块只消费已解析好的值：`runTui(config, resume)`、`runHeadless(task)`、`runWeb(host, port, dev, workspaceRoot)`，都不会再次读取 argv。整个 CLI 由**单个 Commander 程序**实现：默认接口（不使用子命令时）只包含选项标志——`--config <path>`、`-p/--prompt <task>`、`--resume <id>`——而 `web` 是通过 `program.command('web')` 定义的真正子命令。默认接口不接受位置参数，因此 `web` 可以成为真正的子命令且不会发生位置参数冲突，`dsh --help` 也会原生列出 `web`，无需手工拼接命令文本。默认命令和 `web` 子命令的处理函数会设置解析得到的模式，随后对 Commander 无法表达的领域校验调用 `command.error(...)` 立即终止（打印信息并以退出码 1 退出）：`--prompt` 选择 headless 模式；如果任务为空，或调用中还包含 `--config` 或 `--resume`，它会拒绝调用，而不会静默丢弃 TUI 输入；空的 `--resume=` id 会显式失败（agent-loop 把 `''` 视为不恢复）。Commander 会将 `web` token 前后的默认接口选项都解析进 `program.opts()`；由于 `web` 不与默认接口共用任何选项，`web` 子命令的处理函数会拒绝误入的 `--config`/`-p`/`--resume`（`dsh web -p x`、`dsh --config c.yml web`），而不是静默启动服务并丢弃这些选项。`dsh web` 的 `--host`/`--port` 是未经校验、直接透传的覆盖值：适配器既不设置默认值，也不执行校验，只使用 `Number` 将端口字符串转换为数字（schema 要求该值为数字）。`dsh-host-webserver` 的 schemastery `Config`（`host` 是 `127.0.0.1`/`0.0.0.0` 字面量联合类型，`port` 是不大于 65535 的自然数）是默认值与有效性的唯一真源：未提供标志时，随产品提供的 `apps/cli/cordis.yml` 中 `webserver` 配置项保持原值；`AppCLIEntry` 将显式标志的值直接写入该配置项，因此无效的 host/port 会在启动时触发 schema 校验并显式失败，而不是在参数解析阶段失败。`--dev` 会挂载客户端 HMR（热模块替换）驱动，并启用构建产物监视，`--workspace-root <path>` 则是直接透传给 `AppCLIEntry` 的选项（按名称创建 workspace 时使用的父目录）。重复提供 `--resume`，或后续标志被捕获为 `--resume` 或 `--prompt` 的值，都是 Commander 的标准行为（最后一次取值生效／将下一 token 作为值），本适配器不作干预；无效 id 会在下游无法加载会话时显式失败。`--version` 读取本应用的 `package.json`。
-
-`dsh` 不接受位置参数。`--config <path>` 指定一份替代 Cordis 配置树，系统启动该配置树而不是随产品提供的默认配置树；该标志仅用于让演示和测试调用点（`demo:cordis`、`demo:code-mode`、无密钥 PTY 冒烟测试）通过随产品提供的 bin 启动一份示例树。直接运行 `dsh` 会启动随产品提供的配置树，并叠加 `~/.dsh/config.yaml` 个人覆盖；实际用户从不传入 `--config`。
-
-CLI 解析完全位于 `apps/cli` 中。`dsh-app-boot` 提供启动、环境变量、配置和个人覆盖辅助函数，不包含 argv 扫描器。
-
-## 通过启动上下文恢复会话
-
-`dsh --resume <id>` 是恢复持久化会话的唯一方式，无需环境变量。`runTui` 通过 `boot` 的 `prepare(ctx)` 钩子，在启动上下文中提供已解析的 id：`ctx.provide(RESUME_SESSION_ID_KEY, id)`（`dsh-app-boot` 的一项导出，值为 `'resumeSessionId'`）；随产品提供的 tui-agent/cordis 配置将该值作为裸标识符读取：`resumeSessionId: !!js "typeof resumeSessionId === 'string' ? resumeSessionId : undefined"`。这个表达式需要加引号，否则 YAML 会把 `?` 和 `:` 解析为映射；`typeof` 守卫使从未提供该槽位的启动器也能正常运行。`/resume` 原地交接（`process.execve`）根据已解析的值将重新执行时的 argv 构造成 `dsh --resume=<id> [--config <path>]`。
-
-## 唯一的终端入口：`dsh`
-
-`dsh` 是唯一的终端入口；`dsh-tui-demo` 包（package）提供 TUI 应用组合插件，随产品提供的配置会挂载该插件，而该包不提供自己的 bin。`demo:cordis`、`demo:code-mode` 以及 tui-agent 和 cordis-agent 的无密钥 PTY 冒烟测试都通过 `apps/cli/src/bin.ts` 启动，并传入 `--config <path>`。`dsh` 的 TTY 守卫会在启动前拒绝标准输入输出接入管道的调用，并提示自动化场景使用 `dsh -p`；`apps/cli/tests/built-bin.e2e.ts` 锁定了这一行为：该测试将标准输入输出接入管道，并通过普通 Node 运行构建后的 `lib/bin.js`（e2e Vitest 的 include 包含 `apps/cli/tests`）。`cli-demo`、`acp-demo` 和 `jsonrpc-demo` 保留各自的 bin，因为它们分别提供 `dsh` 所没有的独立接口（headless、ACP（Agent Client Protocol）、JSON-RPC）。
-
-## 包拓扑
-
-参数解析留在 `apps/cli`（组装层）内，而不是 `packages/*` 库中：它是这一个应用自身的路由，而非可复用的 seam。`dsh-app-boot` 收缩为纯粹的 boot 胶水代码，不再承担 CLI 解析职责。`commander@^15` 被加入 `apps/cli/package.json`，与 SDK bin 锁定的版本一致。
-
-## 考虑过的替代方案
-
-**保留 `node:util` `parseArgs`，只统一分发。** 已否决：`parseArgs` 没有子命令模型、没有渲染出的帮助、也没有版本标志，因此 `web` 路由和 `--help`/`--version` 仍将保持手写。本仓库其他 CLI 已经选择了 Commander；单独为 `dsh` 引入第二套解析器方式，正是这次变更要消除的碎片化。
-
-**保留 `parseResumeArg` 作为共享辅助函数，并向它喂入 Commander 的残余参数。** 已否决：整件事的核心就是要退役这个定制扫描器。Commander 原生解析 `--resume`（空格和 `=` 形式、缺值、位置无关性）；为这一个标志保留一条平行的手写路径，只会保留这次变更要终结的重复。
-
-**使用裸 `dsh <config>` 位置参数指定替代配置树。** 已否决：根级位置参数与真正的 `web` 子命令无法在同一个 Commander 程序中共存（子命令会占用第一个位置参数）。位置参数会迫使系统把位于首位的 `web` 作为保留 token 分发给另一个解析器，并手工维护一行 `web` 文本，供 `--help` 显示。只有演示和测试调用点需要指定替代配置树，因此 `--config` 标志既能满足这些调用点，又能让默认接口不包含位置参数；这样，`web` 就能在单个程序中成为普通子命令，并由原生 `--help` 展示。
-
-**把参数解析做成 `packages/*` 的 seam。** 已否决：`dsh` 之外没有任何消费方使用它，而能力 seam 不应被提前拆分。这个 Commander 适配器是 `apps/cli` 自身的事务。
-
-**保留 `RESUME_SESSION_ID` 作为恢复通道**：不予采纳。`--resume` 已被解析成 bin 当前持有的值；若再通过环境变量传递并由配置重新读取，只会引入无益的间接层，还会使演示 bin 保留第二条仅依赖环境变量的恢复路径。在启动上下文中提供 id，与 `boot` 的 `prepare` 钩子为 `tuiResumeHost` 提供值所采用的是同一通道。
-
-**保留 `dsh-tui-demo` bin**：不予采纳。它与 `dsh --config <path>` 的功能完全重复；保留它还会迫使演示专用的 `RESUME_SESSION_ID` 回退路径继续存在。配置实际挂载的是该包的插件；冗余的只有作为终端入口的 bin，而 `dsh` 是唯一的终端入口。
-
-## 测试
-
-`apps/cli/tests/args.spec.ts`（新增；`apps/*/tests` 加入 vitest include，`apps/cli/tests` 加入 `tsconfig.host.json`）覆盖适配器的关键行为：根据参数形态进行模式路由（包括 `web --dev` 和 host/port 透传），并通过 `process.exit` spy 捕获适配器的显式报错检查（恢复 id 或提示词为空、`--prompt` 与配置或 `--resume` 混用、未知选项、多余的位置参数）以及 `--help`/`--version` 的退出码。host/port 的有效性由 webserver schema 负责，并由 web 冒烟测试在启动时验证，不属于适配器测试的覆盖范围。`examples/tui-agent/tests/tui-keyless-smoke.e2e.ts` 中的两组 PTY 冒烟测试现在都驱动真实的 `apps/cli/src/bin.ts`：`tui-agent` 组通过 `--config` 启动示例树，`dsh CLI` 组覆盖默认启动、个人覆盖、无效配置、配置对 `--resume` 的接收、通过 `process.execve` 原地恢复交接，以及包含源码路径的系统提示词。`examples/cordis-agent/tests/keyless-smoke.e2e.ts` 同样通过 `dsh` 启动。`packages/ui/app-boot/tests/app-boot.spec.ts` 移除其 `parseResumeArg` 和 `replaceResumeArg` 测试块；TUI 单元测试和快照 fixture（测试前置数据）使用 `dsh --resume {session}` 恢复命令。

-`dsh` 会渲染 `--help`/`--version`，并以一致方式显式报告解析错误；模式路由不依赖标志位置。argv 解析集中在一处，并与 SDK bin 共用一套解析器方式，代价是 `apps/cli` 依赖 `commander`，且 Commander 的解析语义（错误字符串和 `exitOverride` 契约）成为 CLI 入口的一部分。`dsh-app-boot` 不提供任何 CLI 解析接口；需要 `--resume` 式解析的消费方通过组合 Commander 来实现。会话恢复通过启动上下文完成，而不使用环境变量；`dsh` 是唯一的终端入口；`dsh-tui-demo` 包是由配置挂载的插件组合包。

-## Problem
-
-`packages/ui/tui/src/index.ts` had grown past 2000 lines. Most of it was one `createTuiChat` factory: a ~1600-line closure holding roughly forty mutable variables and as many nested closures. Model selection, the ask-user-question queue, and session resume were tangled into that single scope, so a reader could not follow any one concern without holding the whole file in their head, and unrelated edits collided. A prior pass had grouped `src/` into `components/`, `session/`, `extension/`, but the entry file itself and the loose top-level input files (`autocomplete.ts`, `file-autocomplete.ts`, `skill-invocation.ts`, `xml-tool-output.ts`) were untouched.
-
-## Decision
-
-The chat channel's cohesive sub-machines are extracted from `createTuiChat` into `src/chat/`, each a factory that takes an explicit dependency bundle instead of closing over the entry scope:
-
- `chat/model-command.ts` — `createModelController`: the queued `/model` command, the model+reasoning-effort selector overlay, and the selected model's context-window resolution. Owns the context-window cache that the prompt and status views read.
- `chat/questions.ts` — `createQuestionQueue`: the user-interaction provider and the one-at-a-time FIFO ask-user-question overlays.
- `chat/resume.ts` — `createResumeController`: the `/resume` selector, per-candidate summary reads, the pre-handoff preflight, the terminal handoff, and the durable resume-hint command.
- `chat/helpers.ts` — zero-state helpers (`formatCwd`, `gitBranch`, surface/tool-call derivations, session-reference cards), the `HintEditor`, and banner-reveal constants.
- `chat/channel.ts` — `ChatChannelDeps` (the collaborator surface every sub-controller shares) and `ChannelNotice` (mixed in by the controllers that report outcomes). Each `*Deps` extends these, so the shared surface has one definition.
-
-`src/` is reorganized so `chat/` holds every chat-channel concern: the sub-controllers above plus the former input files and the former `session/` files (`timing.ts`, `tokens.ts`) all move under `chat/`. `xml-tool-output.ts` moves under `components/`. The host/process boundary interfaces (`TuiRuntime`, `TuiResumeHost`) move to `src/runtime.ts`. After the split `src/` is `chat/`, `components/`, `extension/`, and the top-level `index.ts` / `config.ts` / `prompt.ts` / `runtime.ts` / `invariant.ts`; `index.ts` drops from 2067 to ~1530 lines and now constructs and wires the three controllers.
-
-The convention for a controller's dependency bundle: stable value collaborators (`ctx`, `resolved`, `palette`, `overlayManager`, and each controller's own services) are destructured once; the channel callbacks (`appendNotice`, `requestRender`, `isDisposed`, `agentStatus`) stay on `deps` so a controller always calls the channel's current implementation. `channel.ts`'s JSDoc states this rule.
-
-## Alternatives considered
-
- **Free functions taking a shared mutable context object.** Rejected: it would re-expose the same forty-field grab-bag the split set out to remove, just under a parameter name.
- **Extracting the status/timing animation controller too.** Deferred: `runningStatus` is read directly by the prompt caret animation in `updatePromptValues`, so a controller boundary there would leak its internal state back through getters — a leaky seam for little gain. It stays inline in `index.ts`.
-
-## Consequences
-
-Each concern is now readable and testable in isolation, and the shared dependency surface is defined once instead of copied into three interfaces. The cost: `index.ts` constructs the controllers and threads the callback bundle, and the model controller is a `let` forward-reference (`updatePromptValues` closes over it, but it is built later once `appendNotice`/`overlayManager` exist), carrying one justified `prefer-const` disable and a deferred first paint.
-
-## Testing
-
-Behavior is unchanged: all existing package tests and TUI snapshots pass without re-recording, which is the contract for this refactor.

-# Agent Note: dsh-tui 聊天通道模块拆分

-Archived: 2026-08-04

-[English](2026-07-27-tui-chat-channel-module-split.md) | 中文
-
-## Problem
-
-`packages/ui/tui/src/index.ts` 已超过 2000 行，其中绝大部分是单个 `createTuiChat` 工厂：一个约 1600 行的闭包，持有约四十个可变变量以及同等数量的嵌套闭包。模型选择、ask-user-question 队列、会话恢复都缠绕在这一个作用域里，读者无法在不把整份文件装进脑子的前提下理清任何单一关注点，互不相关的改动也会彼此冲突。此前一轮已把 `src/` 归组为 `components/`、`session/`、`extension/`，但入口文件本身以及散落在顶层的输入相关文件（`autocomplete.ts`、`file-autocomplete.ts`、`skill-invocation.ts`、`xml-tool-output.ts`）未动。
-
-## Decision
-
-聊天通道内聚的子机制从 `createTuiChat` 中抽出，迁入 `src/chat/`，每个都是接收显式依赖包的工厂，而非闭包捕获入口作用域：
-
- `chat/model-command.ts` — `createModelController`：排队执行的 `/model` 命令、模型加推理力度（reasoning-effort）的选择浮层，以及所选模型上下文窗口的解析。持有供提示行与状态视图读取的上下文窗口缓存。
- `chat/questions.ts` — `createQuestionQueue`：user-interaction provider 以及一次仅一个的 FIFO ask-user-question 浮层。
- `chat/resume.ts` — `createResumeController`：`/resume` 选择器、逐候选摘要读取、交接前预检、终端交接，以及持久化的恢复提示命令。
- `chat/helpers.ts` — 无状态辅助函数（`formatCwd`、`gitBranch`、surface/工具调用派生、会话引用卡片）、`HintEditor`，以及横幅揭示常量。
- `chat/channel.ts` — `ChatChannelDeps`（每个子控制器共享的协作者面）与 `ChannelNotice`（由需要上报结果的控制器混入）。各 `*Deps` 继承它们，使共享面只有一处定义。
-
-`src/` 随之重组，使 `chat/` 汇集所有聊天通道关注点：上述子控制器，加上原来的输入文件与原 `session/` 文件（`timing.ts`、`tokens.ts`）都迁到 `chat/` 之下。`xml-tool-output.ts` 迁到 `components/` 之下。宿主/进程边界接口（`TuiRuntime`、`TuiResumeHost`）迁到 `src/runtime.ts`。拆分后 `src/` 为 `chat/`、`components/`、`extension/`，以及顶层的 `index.ts` / `config.ts` / `prompt.ts` / `runtime.ts` / `invariant.ts`；`index.ts` 从 2067 行降至约 1530 行，现负责构造并接线这三个控制器。
-
-控制器依赖包的约定：稳定的取值型协作者（`ctx`、`resolved`、`palette`、`overlayManager`，以及各控制器自有的服务）一次性解构；通道回调（`appendNotice`、`requestRender`、`isDisposed`、`agentStatus`）保留在 `deps` 上，使控制器始终调用通道当前的实现。`channel.ts` 的 JSDoc 陈述了此规则。
-
-## Alternatives considered
-
- **接收共享可变上下文对象的自由函数。** 否决：那会把拆分本要消除的四十字段大杂烩，仅换个参数名重新暴露出来。
- **同时抽出状态/计时动画控制器。** 推迟：`runningStatus` 被 `updatePromptValues` 中的提示光标动画直接读取，在此设控制器边界会让其内部状态经 getter 反向泄漏——收益甚微的漏隙缝。它继续内联在 `index.ts` 中。
-
-## Consequences
-
-每个关注点现可独立阅读与测试，共享依赖面只定义一次，而非复制进三个接口。代价：`index.ts` 负责构造这些控制器并穿针引线地传入回调包；模型控制器是 `let` 前向引用（`updatePromptValues` 闭包捕获它，但它要待 `appendNotice`/`overlayManager` 就绪后才构造），因而带一处有正当理由的 `prefer-const` 禁用与一次延后的首帧绘制。
-
-## Testing
-
-行为不变：现有的包测试与 TUI 快照全部无需重录即通过，这正是本次重构的契约。

-# Agent Note: Consolidated TUI presentation and navigation
-
-Status: implemented
-Archived: 2026-08-04
-
-English | [中文](2026-07-28-consolidated-tui-presentation.zh.md)
-
-## Problem
-
-The terminal UI accumulated independent presentation rules that interacted poorly: palette roles aliased one another or inverted emphasis on light terminals; tool-card framing, output, and exit markers repeated or competed; injected context was parsed as XML and could not fold reliably; and `/resume` excluded sessions outside the current workspace even when the launcher could reach them. Each symptom appeared local, but the durable decision is one terminal-reading model: a small inspectable palette, status-led cards with recessed bodies, content-independent transcript folding, and workspace-aware navigation.
-
-## Decision
-
-### Palette
-
-`paletteSpec(scheme)` is the single table of SGR codes, close codes, and purposes. `createPalette` derives every wrapper from it and `/palette` prints the same table in the running terminal. Components do not emit their own SGR sequences except for the fixed startup brand gradient. Every close resets every SGR group its open sets.
-
-Duplicate roles are merged: `muted` into `dim`, `added` into `success`, `removed` into `error`, and the unused second accent is removed. `dim` uses `2;39` and closes with `22;39` on both schemes so recessed text stays relative to the terminal foreground rather than becoming a fixed heavy gray on light backgrounds. Colors and attributes are branded separately in TypeScript, allowing attribute/color composition while rejecting nested colors whose reset would discard the outer color.
-
-### Tool cards
-
-A tool card has one colored `Tool / <name>` status header over one dim body. Presenter titles, terminal commands and cwd rows, output, XML text, and fold markers use that body tone. Diff colors remain because red and green carry meaning, and signal markers remain errors.
-
-`renderUnknownXml` receives an explicit body styler for unknown tool results. Terminal presenters parse and remove the model-facing final exit or signal marker before returning `TerminalResultView.output`; the TUI renders the structured status once as its own pill. Truncation, timeout, and sandbox lines remain in the body because the pill does not represent them.
-
-### Injected context and folding
-
-Injected context renders as prose in `ContextCardComponent`, not through the XML tree renderer. Exact matched outer `<system-reminder>` lines are stripped, but mismatched, unpaired, or inline tag-like text remains verbatim. Model-facing content is unchanged. Folding uses the shared `preview` helper after body assembly, so it depends only on row count, never parser success or payload characters.
-
-`Ctrl+O` cycles collapsed, expanded, and hidden. Tool cards disappear in the hidden state together with their card-owned leading gap. Context cards participate in collapsed and expanded states but fall back to collapsed while tools are hidden, because injected instructions are not disposable tool traffic. The hidden phase additionally folds each turn's assistant steps into one message; the [hidden-mode assistant fold Agent Note](../feature/2026-07-29-tui-hidden-mode-assistant-fold.md) owns that rule.
-
-### Cross-workspace resume
-
-The resume picker summarizes all records and owns a current-workspace/all-workspaces scope toggled with Tab. It defaults to the current workspace, adds workspace labels only in the broader scope, and refuses records without a cwd because there is no directory to enter.
-
-`TuiResumeHost.handoff` receives the selected `SessionId` and the cwd re-read during preflight. The CLI changes directory before disposing the current app, so an unreachable directory fails while the terminal can still recover; `execve` then inherits the selected workspace. The launcher also supplies the exit message rather than asking the TUI to reconstruct launcher syntax.
-
-## Alternatives considered
-
-**Keep separate notes and local fixes for each visual symptom.** Rejected: the decisions share one reading hierarchy and repeatedly superseded each other. One owner makes the final palette, card, context, and navigation rules clear without requiring readers to reconstruct chronology.
-
-**Keep aliases and enforce presentation by convention.** Rejected: aliases imply distinctions that do not exist, and nested color resets or incomplete SGR closes fail silently. A single table plus types makes the contract inspectable and mechanically checked.
-
-**Retain framing/output color splits inside tool cards.** Rejected: real cards mixed default foreground, cyan commands, dim cwd, unstyled XML, and dim output. The status header already provides the scan anchor; one recessed body removes noise. Diff colors are the narrow semantic exception.
-
-**Parse or repair injected context as XML.** Rejected: reminder frames are prompting conventions around arbitrary prose containing raw ampersands, comparisons, and placeholder angle brackets. Repairing or escaping it would either guess structure or alter model-visible text.
-
-**Hide context cards with tool cards.** Rejected: context carries injected instructions, not recoverable execution detail. The hidden phase therefore removes only tool traffic.
-
-**Keep resume restricted to one workspace or infer cwd after boot.** Rejected: the restriction forces manual relaunch, while restored header cwd does not control filesystem and shell resolution. The target directory must cross the host seam before process replacement.
-
-**Drop the TUI exit pill or remove model-facing exit markers.** Rejected: the pill is the scannable UI status, while the text marker is the model's status signal. The presenter consumes the marker when constructing the structured view so both audiences receive one representation.
-
-## Consequences
-
-The transcript reads as colored status headers over recessed detail, context presentation is stable for arbitrary prose, and one shortcut controls transcript density. The public `TuiTheme.muted` role is removed; extensions use `dim`. The palette and `renderUnknownXml` contracts are stricter, adding small compile-time friction in exchange for preventing silent style loss.
-
-Cross-workspace resume can move every path-resolving tool to another directory. A missing or inaccessible cwd prevents handoff. The broader picker also makes concurrent access to a shared session store easier to reach; cross-process session locking remains separate work.
-
-The terminal presenter still treats a final output line exactly matching its exit-marker grammar as structured status, so a command that intentionally prints such a line can lose it from the card body. This residual is documented by `dsh-tool-bash`.
-
-## Testing
-
-TUI unit and keyless terminal snapshots cover palette enumeration, light/dark roles, legal and illegal style composition, uniformly dim card bodies, semantic diff colors, marker-free terminal output with one exit pill, prose-preserving context frames, content-independent folding, the three-state Ctrl+O cycle, model filtering, and both resume scopes. CLI handoff tests cover passing the re-read cwd and rejecting directory-entry failure before teardown. Tool-bash tests pin result-marker emission, parse, and stripping as one round trip.

-# Agent Note: 统一的 TUI 呈现与导航

-## Problem
-
-终端 UI 逐步积累了多套彼此干扰的呈现规则：调色板角色互为别名，或在浅色终端中颠倒强调层级；工具卡片的框架、输出和退出标记重复或争夺注意力；注入上下文被当作 XML 解析，无法可靠折叠；`/resume` 即使能通过启动器访问其他工作区，也会排除不属于当前工作区的会话。每个症状看似局部，但持久决策只有一个终端阅读模型：精简且可检查的调色板、以状态为首且正文内收的卡片、与内容无关的记录折叠，以及感知工作区的导航。
-
-## Decision
-
-### 调色板
-
-`paletteSpec(scheme)` 是 SGR 开始码、结束码和用途的唯一表。`createPalette` 从该表派生所有包装器，`/palette` 在运行中的终端打印同一张表。除固定的启动品牌渐变外，组件不自行发出 SGR 序列。每个结束码都重置对应开始码设置的所有 SGR 组。
-
-重复角色被合并：`muted` 并入 `dim`，`added` 并入 `success`，`removed` 并入 `error`，未使用的第二强调色被移除。`dim` 在两种配色方案中都使用 `2;39`，并以 `22;39` 结束，使内收文本相对于终端前景色变暗，而不会在浅色背景上变成固定的深灰色。TypeScript 分别标记颜色和属性，允许属性与颜色组合，同时拒绝会因重置而丢失外层颜色的嵌套颜色。
-
-### 工具卡片
-
-工具卡片由一行带颜色的 `Tool / <name>` 状态标题和一块统一的 dim 正文组成。呈现器标题、终端命令及 cwd 行、输出、XML 文本和折叠标记都使用正文色调。差异颜色继续保留，因为红绿承载语义；信号标记也继续作为错误显示。
-
-`renderUnknownXml` 对未知工具结果显式接收正文样式器。终端呈现器在返回 `TerminalResultView.output` 前解析并移除面向模型的末尾退出或信号标记；TUI 只把结构化状态呈现一次。截断、超时和沙箱信息继续留在正文中，因为状态标记不表达这些事实。
-
-### 注入上下文与折叠
-
-注入上下文由 `ContextCardComponent` 按普通文本呈现，不经过 XML 树渲染器。仅移除精确配对的外层 `<system-reminder>` 行；不匹配、单边或正文内类似标签的文本都原样保留。面向模型的内容不变。折叠在正文组装完成后使用共享 `preview` 辅助函数，因此只取决于行数，不依赖解析是否成功或载荷包含哪些字符。
-
-`Ctrl+O` 在折叠、展开和隐藏之间循环。隐藏状态会连同卡片自有的前导间距一起移除工具卡片。上下文卡片参与折叠和展开状态，但工具隐藏时回到折叠状态，因为注入指令不是可丢弃的工具流量。隐藏阶段还会把每个轮次的 assistant 步骤折叠为一条消息；该规则由[隐藏模式 assistant 折叠 Agent Note](../feature/2026-07-29-tui-hidden-mode-assistant-fold.md)负责。
-
-### 跨工作区恢复
-
-恢复选择器汇总所有记录，并维护可用 Tab 切换的当前工作区/所有工作区范围。默认范围是当前工作区；只有更宽范围才显示工作区标签。没有 cwd 的记录会被拒绝，因为没有可进入的目录。
-
-`TuiResumeHost.handoff` 接收选中的 `SessionId` 和预检时重新读取的 cwd。CLI 在释放当前应用前切换目录，因此无法访问的目录会在终端仍可恢复时失败；随后 `execve` 继承所选工作区。退出提示也由启动器提供，而不是让 TUI 反推启动器命令语法。
-
-## Alternatives considered
-
-**为每个视觉症状保留独立 Agent Note 和局部修复。** 否决：这些决策共享同一阅读层级，而且彼此多次取代。由一份记录统一拥有最终的调色板、卡片、上下文和导航规则，读者无需重建变更顺序。
-
-**保留别名，并依靠约定执行呈现规则。** 否决：别名暗示并不存在的差异；嵌套颜色重置或不完整的 SGR 结束会静默失败。单一表格加类型约束使契约可检查且可机械验证。
-
-**保留工具卡片内部的框架/输出颜色分层。** 否决：真实卡片会混用默认前景、青色命令、dim cwd、无样式 XML 和 dim 输出。状态标题已经提供扫描锚点；统一内收正文能消除噪声。差异颜色是狭窄的语义例外。
-
-**把注入上下文继续解析或修复成 XML。** 否决：提醒框架只是包裹任意普通文本的提示约定，其中会包含原始 `&`、比较表达式和尖括号占位符。修复或转义要么猜测结构，要么改变模型可见文本。
-
-**随工具卡片一起隐藏上下文卡片。** 否决：上下文承载注入指令，不是可恢复的执行细节。因此隐藏阶段只移除工具流量。
-
-**把恢复限制在一个工作区，或在启动后推断 cwd。** 否决：前者迫使用户手动重启；后者恢复的会话头 cwd 并不控制文件系统和 shell 的路径解析。目标目录必须在进程替换前跨过主机接口。
-
-**移除 TUI 退出状态标记，或移除面向模型的退出标记。** 否决：前者是便于扫描的 UI 状态，后者是模型的状态信号。呈现器在构造结构化视图时消费文本标记，使两类受众各看到一种表示。
-
-## Consequences
-
-记录现在表现为带颜色的状态标题和内收细节；上下文对任意普通文本都稳定呈现；一个快捷键控制记录密度。公共 `TuiTheme.muted` 角色被移除，扩展改用 `dim`。调色板和 `renderUnknownXml` 契约更严格，以少量编译期摩擦换取对静默样式丢失的防护。
-
-跨工作区恢复会把所有依赖路径解析的工具移动到另一个目录。cwd 缺失或不可访问时不能交接。更宽的选择范围也使共享会话存储的并发访问更容易触达；跨进程会话锁仍是独立后续工作。
-
-终端呈现器仍会把与退出标记语法完全一致的最后一行输出视为结构化状态，因此命令有意打印这种行时，卡片正文可能丢失该行。`dsh-tool-bash` 已记录这一残余限制。
-
-## Testing
-
-TUI 单元测试和无密钥终端快照覆盖调色板枚举、浅色/深色角色、合法与非法样式组合、统一 dim 卡片正文、保留语义的差异颜色、仅有一个退出状态且正文无标记、普通文本上下文框架、与内容无关的折叠、Ctrl+O 三态循环、模型过滤和两种恢复范围。CLI 交接测试覆盖传递重新读取的 cwd，并在释放前拒绝目录切换失败。tool-bash 测试把结果标记的生成、解析和移除固定为同一轮往返契约。

-# Agent Note: Native TypeScript source launch for dsh
-
-Status: implemented
-Archived: 2026-08-07
-
-English | [中文](2026-07-28-dsh-native-typescript-source-launch.zh.md)

-> The Node-native launch vector is superseded by [dsh source launch through the tsx ESM hook](2026-07-29-dsh-source-launch-tsx-esm.md): Node 26.0.0 removed `--experimental-transform-types`, and the paths loader described here is deleted. The Cordis-config declaration gate (`verify-cordis-config`), the app-boot fail-loud plugin diagnostic, and the vendored `import type` marks remain current.
-
-## Problem
-
-The `dsh` source entry point originally used `tsx` to run `apps/cli/src/bin.ts`, with the same third-party loader implicitly handling both TypeScript transformation and the root tsconfig's `paths` resolution. With Node handling TypeScript natively, it does not apply tsconfig path mappings; resolving through package exports would instead mix potentially stale or nonexistent `lib/` artifacts into the source launch.
-
-Node's transform also does not perform type analysis. A type imported through an ordinary value import remains a runtime ESM request, and TypeScript's `export =` becomes a CommonJS assignment rather than an ESM default export. The source graph therefore has to use explicit type-only imports and native ESM exports; a resolve hook cannot repair incompatible source syntax.
-
-Cordis configuration introduces a separate resolution boundary. Bare plugins in `cordis.yml` do not pass through TypeScript import analysis, so their resolver manifest may omit the required dependencies. The Cordis Loader logs plugin import errors and leaves an entry without a fiber, but does not fail startup itself; a typo in the configuration can therefore produce an incomplete application with exit code 0.
-
-## Decision
-
-The `dsh` TUI, Web, and headless source launches use `node --experimental-transform-types`; Node performs TypeScript transformation without loading `tsx` or esbuild. `bin/dsh`, the root-level `dsh`/TUI/Web demos, and Code Mode TUI enter the same `apps/cli/src/bin.ts` launch chain. Test and E2E launchers retain their existing strategies, and the built `lib/bin.js` continues to run under ordinary Node.
-
-`scripts/tspath-loader.ts` registers only a module resolve hook. It uses `TSX_TSCONFIG_PATH` when set (resolving relative values from the invoking cwd) and otherwise reads the root `tsconfig.json`; `TsconfigPathsResolver` follows that config's `extends` chain through the repository's existing TypeScript development tool, selects exact or wildcard `paths` entries according to tsconfig rules, and maps matching workspace bare specifiers to `.ts`/`.mts`/`.cts` source files or directory index files. Node remains solely responsible for code transformation. The source-only loader is not part of the built CLI and `apps/cli` does not declare `typescript` as a runtime dependency.
-
-Source imports are redirected only when the target package is either the nearest package manifest's own name or one of that manifest's declared runtime dependencies. The Cordis Loader uses the configuration directory URL as the import parent; the resolver then searches upward for the workspace manifest that declares the plugin, so dependency ownership for the shipped `apps/cli/config/base.cordis.yml` plus its surface overlay lies with `apps/cli/package.json`. Specifiers that do not match tsconfig paths, refer to undeclared dependencies, or are not bare all fall back to Node's default resolution.
-
-`verify-cordis-config` performs a one-way completeness check on the resolver manifest: every bare plugin package in a configuration must appear in the corresponding manifest's `dependencies`, while the manifest may contain extra dependencies not referenced by that configuration. The root `AGENTS.md` makes updating the configuration and dependencies together a standing rule.
-
-After the Loader settles, the shared `dsh-app-boot` checks every enabled entry that has no fiber and rejects startup with `plugin(s) failed to load: ...; Cordis startup failed because these plugin(s) could not be resolved`, listing all failed plugins. This diagnostic lives at the app layer and does not change the vendored Loader's startup behavior.
-
-Node-compatible TypeScript is part of this source-launch contract. Vendored Cordis, Loader, Include, HMR, and Schemastery mark erased imports with `import type`. Schemastery uses a native ESM default export and declares `type: module`; its `.mjs` and `.cjs` build outputs retain the existing ESM-default and callable-`require()` behavior. These divergences are recorded in `vendor/README.md`; no runtime behavior is added to the vendored frameworks.
-
-## Alternatives considered
-
-**Continue using `tsx`.** Rejected because `tsx`/esbuild would continue to own TypeScript transformation, so this launch chain could not prove that Node's native transformation works.
-
-**Load the built `lib/` through package exports from the source entry point.** Rejected because this would mix the source plane with the artifact plane; a zero-build development launch could read stale artifacts or fail outright.
-
-**Apply the root tsconfig `paths` unconditionally.** Rejected because this would allow undeclared cross-package imports and Cordis plugins to keep resolving, hiding mismatches between the manifest and the actual runtime graph.
-
-**Transform imports inside the custom loader.** Rejected because type-aware source rewriting would reintroduce a compiler-style transform and make the loader, rather than Node, responsible for TypeScript execution. Making the checked-in source Node-compatible keeps the launch boundary explicit.
-
-## Consequences
-
- TUI/headless retain a zero-build source loop, while Web still builds its frontend artifacts before starting the CLI source entry. TypeScript syntax passes only through Node's native transform; the URL-only loader uses the checkout's root development dependencies and adds no CLI runtime dependency.
- Workspace package imports and Cordis configuration dependencies must both be declared explicitly in the resolver manifest; the static gate prevents configuration from landing before its dependencies, while extra dependencies are not errors.
- Plugin import failures no longer leave an incomplete application with exit code 0; the final error identifies both the Cordis startup failure and the specific plugin names, while the Loader's original error remains earlier in the logs.
- Vendored source in the CLI graph must remain compatible with Node's transform-types module semantics; the local-modification log makes the upstream sync obligation explicit.
- CI's `lib` mode, test/E2E launchers, and other example launchers retain their existing strategies; this native source loader covers only the `dsh` CLI application chain.

-# Agent Note: dsh 原生 TypeScript 源码启动

-> Node 原生启动方案已被 [dsh 通过 tsx ESM hook 源码启动](2026-07-29-dsh-source-launch-tsx-esm.md) 取代：Node 26.0.0 移除了 `--experimental-transform-types`，本文描述的 paths loader 已删除。Cordis 配置声明门禁（`verify-cordis-config`）、app-boot 的显式失败插件诊断以及 vendor 中的 `import type` 标注仍然有效。
-
-## 问题
-
-`dsh` 源码入口原本使用 `tsx` 运行 `apps/cli/src/bin.ts`，TypeScript 转换和根 tsconfig 的 `paths` 解析都由同一个第三方 loader 隐式处理。改由 Node 原生处理 TypeScript 后，Node 不会应用 tsconfig 路径映射；如果改为通过包导出解析，源码启动会混入可能陈旧或不存在的 `lib/` 产物。
-
-Node 的转换也不执行类型分析。通过普通值 import 导入的类型会保留为运行时 ESM 请求，而 TypeScript 的 `export =` 会转换成 CommonJS 赋值，而不是 ESM default export。因此，源码图必须显式使用仅类型导入和原生 ESM 导出；resolve hook 无法修复不兼容的源码语法。
-
-Cordis 配置还引入了另一条解析边界。`cordis.yml` 中的 bare plugin 不经过 TypeScript import 分析，其解析方的 manifest（元数据清单）可能漏掉所需依赖。Cordis Loader 会记录插件 import 错误，并留下没有 fiber 的 entry，但不会让启动本身失败；配置中的拼写错误因此可能得到退出码为 0 的残缺应用。
-
-## 决策
-
-`dsh` 的 TUI、Web 和无头源码启动使用 `node --experimental-transform-types`，由 Node 完成 TypeScript 转换，不加载 `tsx` 或 esbuild。`bin/dsh`、根级 `dsh`/TUI/Web demo 以及 Code Mode TUI 都进入同一条 `apps/cli/src/bin.ts` 启动链路。测试与 e2e 启动器保留各自现有策略，构建后的 `lib/bin.js` 继续由普通 Node 运行。
-
-`scripts/tspath-loader.ts` 只注册一个模块解析钩子。设置 `TSX_TSCONFIG_PATH` 时，它会使用该路径（相对路径从调用方的 cwd 解析），否则读取根 `tsconfig.json`；`TsconfigPathsResolver` 使用仓库已有的 TypeScript 开发工具沿该配置的 `extends` 链解析，按 tsconfig 规则选择精确或 wildcard `paths` 条目，并将命中的 workspace bare specifier 映射到 `.ts`/`.mts`/`.cts` 源文件或目录 index 文件。代码转换始终只由 Node 负责。该源码专用 loader 不属于构建后的 CLI，`apps/cli` 也不会把 `typescript` 声明为运行时依赖。
-
-只有当目标包是最近一层包 manifest 的自身名称或该 manifest 已声明的运行时依赖时，源码 import 才会重定向。Cordis Loader 使用配置目录 URL 作为 import parent；此时 resolver 会向上查找声明该插件的 workspace manifest。因此，已交付的 `apps/cli/config/base.cordis.yml` 及其界面覆盖层所需依赖由 `apps/cli/package.json` 持有。未命中 tsconfig paths、引用未声明依赖或不是 bare specifier 的说明符全部交回 Node 默认解析。
-
-`verify-cordis-config` 对该解析方 manifest 执行单向完整性检查：配置中的每个 bare plugin package 都必须出现在对应 manifest 的 `dependencies` 中，manifest 可以包含该配置未引用的额外依赖。根 `AGENTS.md` 将同步更新配置和依赖定为常驻规则。
-
-Loader 完全停稳后，共享的 `dsh-app-boot` 会检查每个已启用但没有 fiber 的 entry，并拒绝启动，报错为 `plugin(s) failed to load: ...; Cordis startup failed because these plugin(s) could not be resolved`，同时列出全部加载失败的插件。该诊断位于应用层，不改变 vendor 中 Loader 的启动行为。
-
-Node-compatible TypeScript 是这项源码启动契约的一部分。vendor 中的 Cordis、Loader、Include、HMR（热模块替换）和 Schemastery 使用 `import type` 标记会被擦除的导入。Schemastery 使用原生 ESM default export 并声明 `type: module`；其 `.mjs` 和 `.cjs` 构建产物分别保留现有的 ESM default export 行为和 `require()` 返回可调用值的行为。这些差异记录在 `vendor/README.md` 中；没有为 vendor 中的框架新增运行时行为。
-
-## 曾考虑的替代方案
-
-**继续使用 `tsx`。** 不采用，因为 `tsx`/esbuild 会继续负责 TypeScript 转换，本启动链路无法因此证明 Node 原生转换可用。
-
-**让源码入口通过包导出加载构建后的 `lib/`。** 不采用，因为这会混合 source plane 与 artifact plane；无需预先构建的开发启动可能读取陈旧产物或直接失败。
-
-**无条件应用根 tsconfig `paths`。** 不采用，因为这会让未声明的跨包 import 和 Cordis 插件继续成功解析，从而掩盖 manifest 与实际运行图之间的不一致。
-
-**在自定义 loader 内转换 import。** 不采用，因为感知类型的源码改写会重新引入编译器式转换，并让 loader 而非 Node 负责执行 TypeScript。使签入仓库的源码兼容 Node，可以让启动边界保持显式。
-
-## 后果
-
- TUI／无头界面保留零构建源码回路，Web 仍会在启动 CLI 源码入口前构建前端产物。TypeScript 语法只经过 Node 原生转换；仅处理 URL 的 loader 使用 checkout 根目录的开发依赖，不增加 CLI 运行时依赖。
- workspace package import 和 Cordis 配置依赖都必须在解析方 manifest 中明确声明；静态门禁防止配置先于依赖落地，额外依赖不构成错误。
- 插件 import 失败不再留下退出码为 0 的残缺应用；最终错误同时说明 Cordis 启动失败及具体插件名，Loader 的原始错误仍会保留在更早的日志中。
- CLI 源码图中的 vendor 源码必须与 Node 的 transform-types 模块语义兼容；本地修改记录明确了上游同步义务。
- CI 的 `lib` 模式、测试／e2e 启动器和其他示例启动器保留各自现有策略；该原生源码 loader 只覆盖 `dsh` CLI 应用链路。

-# Agent Note: WebSocket carrier for browser downlinks
-
-Status: implemented
-Archived: 2026-08-27
-
-English | [中文](2026-08-04-websocket-downlink-carrier.zh.md)
-
-## Problem
-
-The browser Web GUI has long used two SSE responses for `events.mux` and `events.host`. HTTP/1.1 browsers typically allow only about six concurrent connections per origin; each page permanently occupying two makes same-origin tabs, plugin resources, and ordinary RPCs contend for connection slots, and reaching the limit causes requests to queue rather than merely slowing them down. The RPC protocol itself is channel-independent: a constraint of the browser's physical carrier must not leak into the session/runtime object layer.
-
-## Decision
-
-The real browser carrier opens one independent WebSocket for each downlink stream class: `/api/events.mux` sends only `MuxFrame`, and `/api/events.host` sends only `HostFrame`. Each text message is one complete `ServerRequest` JSON document; the client continues to validate the envelope first, then the concrete frame union for that path, and passes the narrow `RpcRequest<Frame>` form to the existing `ConnectionController`. The streams retain independent lifecycles and provide no cross-stream ordering guarantee; either one ending still fails the entire connection generation and rebuilds it under the existing backoff policy.
-
-WebSocket carries only the host→browser downlink. All client→host unary calls and `respond` operations for server requests continue to use the existing `POST /api/*`; the WebSocket accepts no client application messages. `WebApiClient` therefore holds HTTP `fetch` for uplink and WebSocket for downlink, while the fixture and `InProcessApiClient(toFetchHandler(api))` continue to implement the same two-stream `IApiClient` abstraction. The in-process fetch carrier retains SSE encoding and decoding to verify the channel-independent protocol's isomorphism, but network GET requests to `/api/events.*` answer only Upgrade Required and do not provide a browser compatibility fallback.
-
-## Upgrade and lifecycle boundaries
-
-`dsh-host-webserver` provides an exact upgrade-route registration point alongside ordinary routes, dispatches Node upgrade sockets by pathname only, contains raw-socket errors, and waits for surviving upgraded connections to close during server teardown; it knows nothing about Harness frames or WebSocket messages. `dsh-client-connection` owns the WebSocket handshake, frame output, and stream cancellation. Before upgrade it applies the `/api` Host/Origin checks followed by the same signed browser-cookie authentication as unary HTTP. An untrusted authority or cross-origin Origin receives 403; a trusted but unauthenticated request receives 401; neither starts a Remote stream.
-
-A browser abort or socket close cancels the corresponding host stream; plugin teardown also waits for that source iterator's cleanup. If a host stream throws midway, the carrier sends one existing `stream/error` frame and then closes the socket; the client treats that frame as connection loss rather than delivering it to a business sink. Each WebSocket reports open independently, and the existing readiness handshake still waits until mux and host are both open and the `host.describe` HTTP call has succeeded before publishing connected.
-
-## Verification
-
-Webserver contract tests pin upgrade-pathname dispatch, duplicate-registration rejection, disposal, and teardown; connection real-network tests pin each WebSocket's trust check, open, schema envelope, frame order, stream error, and close cancellation; client tests also prove that downlinks create `ws:`/`wss:` URLs while unary calls and `respond` still use HTTP `fetch`. The assembled keyless browser replay continues to cover Chromium, a real host, HTTP uplink, and the full WebSocket downlink chain.
-
-## Alternatives considered
-
-**Multiplex mux and host over one WebSocket.** This would add a channel tag, a multiplexing queue, and a single-connection backpressure policy, and would change the existing two-stream readiness semantics. Two WebSockets already avoid the HTTP/1.1 six-connection limit while keeping this change in the physical carrier layer.
-
-**Move unary calls and respond to a full-duplex WebSocket as well.** This would rewrite timeout, cancellation, HTTP-status, trust-fence, and request-correlation behavior without adding any benefit for the current downlink connection-slot problem. HTTP uplink is an explicitly retained boundary.
-
-**Keep a network SSE fallback.** Two carriers would let the production browser path silently fork because of proxy or handshake differences and would leave the connection-limit problem in a supported branch. During prerelease, only WebSocket downlink ships; the existing reconnect behavior and connection state expose failures explicitly.
-
-**Rely on HTTP/2 for greater connection concurrency.** The built-in development server uses plaintext Node HTTP/1.1, and a deployment's fronting proxy is not a product invariant. The physical downlink directly uses a browser primitive outside that connection pool.
-
-## Consequences
-
-Each Web page still has two long-lived downlink connections, but they no longer consume the browser's six-connection HTTP/1.1 quota. The runtime continues to consume the original two streams and retains all reconnect, stream-repair, and cross-stream unordered semantics. The cost is one more upgrade-registration surface in the webserver, a WebSocket implementation dependency in the connection package's host half, and separate maintenance of the browser WebSocket and in-process SSE physical codecs. They share the same `ServerRequest`/frame schemas and `IApiClient` semantics, avoiding a second application protocol.

-# Agent Note: 浏览器下行 WebSocket 载体
-
-Status: implemented
-Archived: 2026-08-27
-
-[English](2026-08-04-websocket-downlink-carrier.md) | 中文
-
-## Problem
-
-浏览器 Web GUI 的 `events.mux` 与 `events.host` 长期使用两条 SSE（Server-Sent Events）响应。HTTP/1.1 浏览器通常只允许每个来源约六条并发连接；每个页面永久占住两条会让同源多标签页、插件资源和普通 RPC 争抢连接槽，达到上限后不是降速而是排队阻塞。RPC 协议本身是通道无关的，约束来自浏览器物理载体，不应渗入会话/运行时对象层。
-
-## Decision
-
-浏览器真实载体为两类下行流各开一条独立 WebSocket：`/api/events.mux` 只发送 `MuxFrame`，`/api/events.host` 只发送 `HostFrame`。每条文本消息是一份完整的 `ServerRequest` JSON；客户端继续先校验信封，再按路径校验具体 frame union，并把窄形 `RpcRequest<Frame>` 交给既有 `ConnectionController`。两条流保持独立生命周期和无跨流顺序保证，任一条结束仍使整个 connection generation 失败并按既有退避策略重建。
-
-WebSocket 只承担 host→browser 下行。所有 client→host unary 调用和对 server request 的 `respond` 继续使用既有 `POST /api/*`；不在 WebSocket 上接收任何客户端业务消息。`WebApiClient` 因而同时持有 HTTP `fetch` 上行与 WebSocket 下行，而 fixture（测试前置数据）和 `InProcessApiClient(toFetchHandler(api))` 继续实现同一 `IApiClient` 双流抽象。进程内 fetch 载体保留 SSE 编解码来检验通道无关的协议同构，但网络上对 `/api/events.*` 的 GET 请求只返回 upgrade required，不作为浏览器兼容回退。
-
-## Upgrade 与生命周期边界
-
-`dsh-host-webserver` 提供与普通 route 并列的精确 upgrade-route 注册点，只按 pathname 分发 Node upgrade socket，隔离原始 socket 错误，并在 server teardown 期间等待仍存活的升级连接关闭；它不认识 Harness 帧或 WebSocket 消息。`dsh-client-connection` 拥有 WebSocket handshake、frame 写出和流取消。upgrade 前先执行 `/api` Host／Origin 校验，再执行与一元 HTTP 相同的签名浏览器 cookie 认证。未受信任的 authority 或跨来源 Origin 得到 403；Host 可信但未认证的请求得到 401；两者都不会启动 Remote stream。
-
-浏览器 abort 或 socket close 会取消对应的 host 流；插件 teardown 还会等待该 source iterator 完成清理。host 流中途抛错时，载体发送一个现有的 `stream/error` frame 后关闭 socket；客户端把该 frame 收敛为连接丢失，不投递给业务 sink。每条 WebSocket 独立报告 open，既有 readiness handshake 仍等待 mux、host 都 open 且 `host.describe` HTTP 调用成功后才发布 connected。
-
-## Verification
-
-webserver 约定测试钉住 upgrade pathname 分发、重复注册拒绝、资源释放与 teardown；connection 的真实网络测试钉住两条 WebSocket 各自的信任检查、open、schema 信封、frame 顺序、流错误与关闭时取消；客户端测试同时证明下行创建 `ws:`／`wss:` URL，而 unary 与 `respond` 仍调用 HTTP `fetch`。组装后的 keyless 浏览器回放继续覆盖 Chromium、真实 host、HTTP 上行与 WebSocket 下行整链。
-
-## Alternatives considered
-
-**用一条 WebSocket 复用 mux 与 host。** 这会新增 channel tag、复用队列与单连接背压策略，并改变现有双流 readiness 语义；两条 WebSocket 已避开 HTTP/1.1 六连接上限，同时让本次变更保持在物理载体层。
-
-**把 unary 与 respond 一并迁入全双工 WebSocket。** 这会改写超时、取消、HTTP 状态、信任栅栏和请求关联行为，却不能为当前的下行连接槽问题带来额外收益；上行 HTTP 是明确保留的边界。
-
-**保留网络 SSE 回退。** 双载体会让生产浏览器路径可因代理或握手差异静默分叉，并让连接上限问题继续存在于一个受支持分支；预发布阶段只交付 WebSocket 下行，失败由既有重连与连接状态显式呈现。
-
-**依赖 HTTP/2 扩大并发连接能力。** 内置开发服务器是明文 Node HTTP/1.1，部署前置代理也不是产品可依赖的不变式；物理下行应直接使用不受该连接池限制的浏览器原语。
-
-## Consequences
-
-每个 Web 页面仍有两条长期下行连接，但它们不再消耗浏览器的 HTTP/1.1 六连接配额；运行时继续消费原有双流并保留所有重连、流修复和跨流无序语义。代价是 webserver 多一个 upgrade 注册面，connection 包的 host 半侧新增一项 WebSocket 实现依赖，并需分别维护浏览器 WebSocket 与进程内 SSE 两种物理编解码；它们共享同一 `ServerRequest`／frame schema 和 `IApiClient` 语义，避免形成第二套业务协议。

-# Agent Note: Feature-owned tabs in Plugins settings
-
-Status: implemented
-Archived: 2026-08-22
-
-English | [中文](2026-08-11-plugin-settings-tabs.zh.md)
-
-## Problem
-
-Plugin configuration and the read-only Loader inventory each registered a top-level `settings.section`. They described the same Plugins domain but occupied two navigation rows, split search and configuration into unrelated pages, and gave the Settings shell no principled way to present them together. Combining their components directly would instead make one feature plugin import and own the other feature's data lifecycle.
-
-## Decision
-
-`@deepseek-ai/dsh-client-ui-settings-plugins` owns the single `settings.section` contribution with id `plugins`. It renders the shared title and compact tab chrome, declares the root-scoped list slot `settings.plugins.tab`, and projects that ledger's id, order, and locale-following label into its tabs. The slot's canonical type lives in `ui-settings`, so a tab contributor depends on the Settings domain contract rather than on another feature plugin.
-
-The section owner contributes a `configurable` tab that declares the existing nested `settings.plugin.item` list. Configuration cards keep their namespace bindings, draft state, validation, and writes unchanged. `@deepseek-ai/dsh-client-ui-settings-plugin-inventory` contributes an `all` tab to `settings.plugins.tab`; its Host Loader observer, generated Remote namespace, DTO, and search semantics remain unchanged. Disabled inventory entries omit the redundant unmounted runtime state from summaries and details, while enabled entries continue to expose their Cordis phase.
-
-The first ordered tab is selected by default. A tab mounts only when first selected and then remains mounted but hidden while the Plugins section stays mounted. This delays the inventory RPC until the user opens **Plugin list** and preserves drafts, search text, disclosure state, and the fetched snapshot while switching tabs. Closing Settings unmounts the section, so reopening it obtains a fresh inventory snapshot when that tab is selected again.
-
-Both registrations use `ctx.slots.inject()`. If the section declarer unloads, the tab declaration and every contribution collapse with it; redeclaration lets each feature re-register without a static import or activation-order dependency.
-
-## Alternatives considered
-
-**Keep two Settings navigation rows and only rename them.** Rejected because the duplication is structural, not copy-related: both pages still represent the same Plugins domain and compete for navigation space.
-
-**Import the inventory component into `ui-settings-plugins`.** Rejected because the configuration plugin would then own another plugin's Remote dependency and lifecycle. It would also turn an optional browser contribution into a package-level dependency.
-
-**Hard-code the two tab labels and components in the section owner.** Rejected because a third feature would require editing the owner, and HMR teardown could leave chrome for a contribution that no longer exists. The slot ledger already provides identity, ordering, localization, and cascade semantics.
-
-**Move Plugins aggregation into `ui-settings-general`.** Rejected because the Settings shell owns generic navigation and modal chrome, not feature content. Adding Plugins-specific tabs there would make every future Plugins view a shell change.
-
-## Consequences
-
-Settings has one Plugins navigation row, ordered before Agent Presets, with **Plugin configuration** and **Plugin list** tabs. Agent Presets remains an independent section because it edits per-session agent compositions rather than the live Host Loader tree.
-
-Feature ownership remains explicit: `ui-settings-plugins` owns the Plugins page and editable cards, `ui-settings-plugin-inventory` owns the read-only inventory view, and the Host/RPC path does not change. A new Plugins view can join by registering one `settings.plugins.tab` contribution.
-
-The aggregation depends on the section owner being composed: without `ui-settings-plugins`, `ui-settings-plugin-inventory` waits for a tab declaration and renders nothing. That is an intentional composition dependency carried by the slot registry rather than a static package import.

-## 问题
-
-插件配置与只读 Loader 清单各自注册了一个顶层 `settings.section`。两者描述同一个“插件”领域，却占据两行导航，把搜索与配置拆成互不相关的页面，也没有给 Settings 外壳一个有原则的聚合方式。若直接合并两者的组件，则会让一个功能插件 import 并拥有另一个功能的数据生命周期。
-
-## 决策
-
-`@deepseek-ai/dsh-client-ui-settings-plugins` 拥有唯一一个 id 为 `plugins` 的 `settings.section` 贡献。它渲染共享标题和紧凑标签栏，声明根级列表 slot `settings.plugins.tab`，并把该记录中的 id、order 与跟随语言的 label 投影成标签页。该 slot 的规范类型位于 `ui-settings`，因此标签页贡献方依赖设置领域约定，而不是依赖另一个功能插件。
-
-分区拥有方贡献 `configurable` 标签页，由它声明既有的嵌套 `settings.plugin.item` 列表。配置卡片原有的命名空间绑定、草稿状态、校验与写入均保持不变。`@deepseek-ai/dsh-client-ui-settings-plugin-inventory` 向 `settings.plugins.tab` 贡献 `all` 标签页；它的 Host Loader 观察器、生成的 Remote 命名空间、DTO 与搜索语义保持不变。已停用的清单条目会在摘要和详情中省略重复的“未挂载”运行状态，已启用条目仍显示其 Cordis 阶段。
-
-默认选择顺序中的第一个标签页。某个标签页只有首次被选择时才挂载，之后在“插件”分区保持挂载期间只隐藏而不卸载。这样会把清单 RPC 延迟到用户打开**插件列表**时，并在切换标签页时保留草稿、搜索文本、折叠状态和已读取的快照。关闭 Settings 会卸载该分区，因此再次打开后，重新选择该标签页时会取得新的清单快照。
-
-两项注册都使用 `ctx.slots.inject()`。分区声明方卸载时，标签 slot 及其全部贡献随之折叠；重新声明后，每项功能都能重新注册，无需静态 import，也不依赖激活顺序。
-
-## 备选方案
-
-**保留两行 Settings 导航，只改名称。** 否决，因为重复是结构问题，而非文案问题：两个页面仍然代表同一个“插件”领域，并继续争夺导航空间。
-
-**把清单组件 import 进 `ui-settings-plugins`。** 否决，因为配置插件会因此拥有另一个插件的 Remote 依赖与生命周期，也会把可选的浏览器贡献变成包级依赖。
-
-**在分区拥有方硬编码两个标签页的名称和组件。** 否决，因为第三项功能需要修改拥有方，HMR teardown 也可能留下已不存在贡献的界面框架。slot 记录已经提供标识、顺序、本地化与级联语义。
-
-**把“插件”聚合移入 `ui-settings-general`。** 否决，因为 Settings 外壳拥有通用导航与模态界面框架，而不拥有功能内容。把“插件”专属标签页放在那里，会让今后每一种“插件”视图都需要修改外壳。
-
-## 影响
-
-Settings 只有一行“插件”导航，排在“Agent 预设”之前，包含**插件配置**与**插件列表**两个标签页。“Agent 预设”仍是独立分区，因为它编辑每个会话的 agent 组装，而非实时 Host Loader 树。
-
-功能所有权保持明确：`ui-settings-plugins` 拥有“插件”页面与可编辑卡片，`ui-settings-plugin-inventory` 拥有只读清单视图，Host／RPC 路径不变。新的“插件”视图只需注册一个 `settings.plugins.tab` 贡献即可加入。
-
-该聚合依赖分区拥有方被组装：没有 `ui-settings-plugins` 时，`ui-settings-plugin-inventory` 会等待标签 slot 的声明且不渲染任何内容。这是通过 slot 注册表承载的有意组合依赖，而不是静态包 import。

-
-## Problem
-
-The outer `run_code` tool persisted complete rendered content, but its UI presenter ignored that content and rebuilt the card body from a logs-only `presentationMeta` projection. A result-only run appeared correct because an empty presenter body let consumers fall back to `tool/result.content`. Once the program emitted a log, the presenter supplied non-empty content, that fallback stopped, and the returned value disappeared from the completed card. A spill policy's final head/tail preview was vulnerable to the same split ownership whenever captured logs made the stale projection non-empty.
-
-Nested Code calls never owned cards, so producing metadata for the outer call solely to reconstruct one incomplete card also obscured the intended one-card boundary.
-
-## Decision
-
-The canonical tool registry pipeline owns the final model-facing outer content. On success, the `run_code` output renderer renders captured logs followed by the return value or the explicit no-output marker. Runtime failures and pre-execution policy denials are normalized into error content by `ToolRegistry` without invoking that renderer. A post-execute block runs after successful rendering and replaces the result with error content; other post-execute policy and spill decisions may replace content before persistence.
-
-`run_code` omits `presentResult`. The established generic result fallback keeps the pending program title and renders the raw final `tool/result.content`; that durable, replayable, post-policy projection is the card's only result-content source. The host API proxy therefore omits a separate result view instead of serializing the same content in both `event.data.content` and `view.view.content`. The redundant logs-only `presentationMeta` projection remains removed.
-
-Nested dispatch remains unchanged. Calls marked by `exec.parent` emit `tool/code-dispatch` events (full rendered content) but no `tool/call` or `tool/result` surface cards, so one outer `run_code` invocation still produces exactly one card.
-
-## Testing
-
-Tool unit coverage drives logs-only, result-only, logs-plus-result, no-output, spilled-result, and failure outcomes through the canonical registry, then pins the durable content and absence of a result presenter. A host-mux regression uses a call-only presenter to prove the result frame carries raw content exactly once and no view. These cases prove stale metadata cannot replace final content without making the host duplicate that content.
-
-The keyless ACP backend and TUI Code Mode snapshots execute one outer program that performs two nested bash calls, logs `captured output`, and returns `CODE_ONE+CODE_TWO`. The persisted ACP log pins the complete result; the TUI surface shows one completed outer card containing both lines and no nested cards.
-
-## Alternatives considered
-
-**Append the return value to logs metadata.** Rejected because metadata would duplicate the renderer, need a second stable formatting contract for every JSON root, and still miss post-policy content replacement or spill previews.
-
-**Merge presenter metadata with `result.content`.** Rejected because the rendered content already contains the logs; merging would duplicate them and require brittle deduplication.
-
-**Forward `result.content` through a generic result presenter.** Rejected because the durable event already carries that content and UI consumers already have a generic raw-content fallback. The host mux serializes a tool-owned result view beside the event, so forwarding would duplicate the rendered content in one frame merely to recreate the fallback; the default worker alone admits a 64 MiB variable-payload budget before rendering.
-
-**Create one card per nested dispatch.** Rejected because intermediate values are intentionally execution-local and never model-facing. Multiple cards would expose an implementation trace instead of the single Code Mode operation the model and user invoked.
-
-## Consequences
-
-TUI and JSON-RPC/Web display the same complete content the model receives and replay persists, including post-policy spill previews, through their generic result fallback. The host API retains the pending program title without duplicating the raw result in a separate view payload. New `run_code` results no longer carry the optional logs metadata, but this requires no session-format bump: existing records remain valid because presentation reads their durable rendered content.

-## 问题
-
-外层 `run_code` 工具会持久化完整的渲染内容，但其 UI 展示器忽略了这些内容，转而根据仅含日志的 `presentationMeta` 投影重新构建卡片正文。仅有结果的运行看似正确，是因为展示器正文为空时，消费方会回退到 `tool/result.content`。只要程序输出一条日志，展示器就会提供非空内容，回退随即停止，返回值便会从完成态卡片中消失。当已捕获的日志使陈旧投影变为非空时，输出落盘策略最终生成的头尾预览也会受到同一职责拆分的影响。
-
-嵌套 Code 调用从不生成自己的卡片。因此，仅仅为了重建这一张不完整卡片而给外层调用生成元数据，还掩盖了每次外层调用只生成一张卡片的预期边界。
-
-## 决策
-
-规范的工具注册表流水线负责最终面向模型的外层内容。成功时，`run_code` 输出渲染器先渲染已捕获的日志，然后渲染返回值或显式的无输出标记。运行时失败和执行前策略拒绝由 `ToolRegistry` 归一化为错误内容，过程中不会调用该渲染器。Post-execute 阻断发生在成功渲染之后，并把结果替换为错误内容；其他 post-execute 策略与输出落盘决策可以在持久化之前替换内容。
-
-`run_code` 不提供 `presentResult`。既有的通用结果回退机制会保留待完成的程序标题，并渲染原始的最终 `tool/result.content`；这一持久、可回放且经过 post-policy 处理的投影是卡片中结果内容的唯一来源。宿主 API 代理因此不提供单独的结果视图，而不会在 `event.data.content` 与 `view.view.content` 中重复序列化同一内容。冗余的仅含日志的 `presentationMeta` 投影继续保持移除状态。
-
-嵌套分发保持不变。带有 `exec.parent` 标记的调用会发出 `tool/code-dispatch` 事件（携带完整渲染内容），但不会生成与 `tool/call` 或 `tool/result` 对应的界面卡片，因此一次外层 `run_code` 调用仍然只会生成一张卡片。
-
-## 测试
-
-工具单元测试通过规范注册表覆盖仅有日志、仅有结果、日志与结果并存、无输出、结果落盘和失败的结果，然后固定持久内容以及结果展示器不存在这一事实。宿主 mux 回归测试使用仅有调用的展示器，证明结果帧恰好携带一次原始内容，且不含视图。这些案例证明陈旧元数据无法替换最终内容，同时不会让宿主重复该内容。
-
-无密钥的 ACP（Agent Client Protocol）后端快照与 TUI Code Mode 快照会执行一个外层程序：程序进行两次嵌套 bash 调用，记录 `captured output`，并返回 `CODE_ONE+CODE_TWO`。ACP 持久化日志固定完整结果；TUI 界面只显示一张完成态外层卡片，其中包含这两行内容，且没有嵌套卡片。
-
-## 备选方案
-
-**把返回值追加到日志元数据：**不予采纳。元数据会与渲染器重复，并且需要为每一种 JSON 根另行维护稳定的格式化契约；post-policy 内容替换或输出落盘预览仍然会被遗漏。
-
-**把展示元数据与 `result.content` 合并：**不予采纳。渲染内容已经包含日志；合并会造成重复，还需要依赖脆弱的去重逻辑。
-
-**通过通用结果展示器转发 `result.content`：**不予采纳。持久事件已经携带该内容，UI 消费方也已有通用的原始内容回退机制。宿主 mux 会在事件旁序列化工具拥有的结果视图，因此转发仅仅是为了重建该回退机制，却会在一个帧中重复渲染内容；仅默认 worker 在渲染前允许 64 MiB 的可变载荷预算。
-
-**为每次嵌套分发创建一张卡片：**不予采纳。中间值有意只存在于执行期间，永远不面向模型。多张卡片会暴露实现轨迹，而不是模型与用户调用的单次 Code Mode 操作。
-
-## 影响
-
-TUI 与 JSON-RPC／Web 通过通用结果回退机制显示与模型接收及回放持久化相同的完整内容，其中包括 post-policy 输出落盘预览。宿主 API 保留待完成的程序标题，同时不在单独的视图负载中重复原始结果。新的 `run_code` 结果不再携带可选的日志元数据，但无需提升会话格式版本：现有记录仍然有效，因为展示逻辑会读取其中持久化的渲染内容。

-# Agent Note: A collapsed sidebar retains its control rail
-
-Status: implemented
-Archived: 2026-07-26
-
-English | [中文](2026-07-22-collapsed-sidebar-control-rail.zh.md)
-
-## Problem
-
-The sidebar close action persisted a zero width preference, and the layout mapped that preference to a zero-width grid track. The only sidebar toggle and the settings entry both lived inside that clipped track, so closing the sidebar removed every visible recovery control. Reloading preserved the closed preference and reproduced the lockout.
-
-## Decision
-
-The layout maps a closed sidebar (persisted width `0`) to the fixed `SIDEBAR_COLLAPSED` width of 56px: a 24px icon column between the sidebar's 16px horizontal paddings. The sidebar track is fixed-width in the solver — open or collapsed it never concedes to viewport pressure (only details shrinks, then auto-closes) — and the rail retains its right border while the stored expanded width remains untouched.
-
-`AppFrame` marks the sidebar collapsed from the persisted width preference rather than from the resolved track width, removes the resize handle while collapsed, and passes `collapsed` to the sidebar slot as owner props from the render site. Collapse and expand animate: the frame transitions `grid-template-columns` (and the remaining handle its `left`) on the deepsuite sider curve — `--ds-ease-in-out` over `--ds-transition-duration-slow`, both supplied by ui-theme's base sheet; transitions pause during drags and under `prefers-reduced-motion`.
-
-`SidebarRoot` reads the owner `collapsed` prop and transitions as a slide + crossfade: the expanded content freezes at its width (inline style) and fades out in place over 150ms while the sliding grid column clips it — nothing reflows mid-slide. At settle the wide-only content (brand, labels, input, session tree) unmounts — dropping the sessions subscription and leaving the rendered and accessibility trees — and the control rows snap to the rail (open toggle, new session, new workspace, search, the same top-down order as their expanded rows) fading in as the slide ends. Each rail control keeps its expanded counterpart's behavior (the search icon expands the sidebar and focuses the search box after the slide), carries a tooltip, and the toggle rests as the whale mark with the panel icon on hover. The search query lives with the root and survives the round trip.
-
-## Alternatives considered
-
- **Render an expand button over the center column** — rejected because it recovers only the toggle, not the persistent settings area, and splits sidebar chrome across two package owners.
- **Keep a zero-width grid track and let the rail overflow it** — rejected because the rail would overlap the center column and leave hit testing and responsive geometry disconnected from the grid.
- **Keep the complete sidebar tree mounted and hide it with clipping** — rejected because hidden controls remain in the semantic tree and continue subscribing and rendering even though only two controls belong in the collapsed state.
-
-## Consequences
-
- A collapsed sidebar reserves 56px instead of yielding the entire width to the center column. Expanding restores the persisted width and drag behavior.
- The settings entry remains visible but retains its existing placeholder behavior; this change does not introduce an account or settings screen.
- Layout solver tests pin the compact width, sidebar component tests pin the visible controls, and the keyless real-bundle web smoke test pins collapse and recovery through the assembled client.

-# Agent Note: 侧边栏折叠后保留控制栏
-
-Status: implemented
-Archived: 2026-07-26
-
-[English](2026-07-22-collapsed-sidebar-control-rail.md) | 中文
-
-## 问题
-
-侧边栏关闭操作会持久化宽度偏好 `0`，布局再将该偏好映射为宽度为零的网格轨道。侧边栏唯一的开关与设置入口都位于这个被裁切的轨道内，因此关闭侧边栏会移除所有可见的恢复控件。页面重新加载时仍会读取关闭偏好，从而再次陷入无法恢复的状态。
-
-## 决策
-
-布局将关闭的侧边栏（持久化宽度为 `0`）映射为固定的 `SIDEBAR_COLLAPSED` 宽度 56px：在侧边栏两侧各 16px 的水平内边距之间放置一列 24px 的图标控件。侧边栏轨道在求解器中是定宽的——无论展开还是折叠都不向视口压力让步（只有 details 会收缩、继而自动关闭）；控制栏保留右侧边框，已存储的展开宽度保持不变。
-
-`AppFrame` 根据持久化的宽度偏好标记侧边栏是否折叠，而不是根据求解后的轨道宽度来判断；折叠时移除尺寸调整手柄，并在渲染点把 `collapsed` 作为 owner props 传给侧边栏插槽。折叠与展开带动画：frame 对 `grid-template-columns`（以及余下手柄的 `left`）应用 deepsuite 侧栏曲线过渡——`--ds-ease-in-out` 配 `--ds-transition-duration-slow`，两个变量由 ui-theme 的 base 表提供；拖拽期间和 `prefers-reduced-motion` 下过渡暂停。
-
-`SidebarRoot` 读取 owner 的 `collapsed` 属性，过渡是滑动 + 交叉淡变：展开内容以内联样式冻结在原宽度、150ms 原地淡出，滑动中的网格列裁切它——滑动途中不发生任何重排。settle 时宽态专属内容（品牌标识、文字标签、输入框、会话树）卸载——随之退订会话列表并离开渲染树与可访问性树——控件行落位到控制栏（打开开关、新建会话、新建工作区、搜索，自上而下与展开态各行顺序一致），随滑动结束淡入。每个控制栏控件保持与展开态对应控件一致的行为（搜索图标展开侧边栏并在滑动结束后聚焦搜索框）并带 tooltip；开关静止时显示鲸鱼标，悬停切换为面板图标。搜索关键词由根组件持有，折叠往返后保留。
-
-## 曾考虑的替代方案
-
- **在中心列上方渲染展开按钮**：不予采纳，因为这只能恢复开关，无法保留常驻设置区域，同时还会让侧边栏 UI 由两个包（package）分别持有。
- **保留宽度为零的网格轨道，让控制栏溢出显示**：不予采纳，因为控制栏会与中心列重叠，还会使命中测试和响应式几何关系脱离网格布局。
- **保持完整侧边栏树挂载，并通过裁切将其隐藏**：不予采纳，因为隐藏控件仍留在语义树中，而且会继续订阅和渲染，尽管折叠状态下只需要两个控件。
-
-## 后果
-
- 折叠的侧边栏占用 56px，而不是把全部宽度让给中心列。展开时恢复持久化宽度与拖动行为。
- 设置入口持续可见，但保留既有占位行为；本次改动不提供账户或设置页面。
- 布局求解器测试固定紧凑宽度，侧边栏组件测试固定可见控件，基于真实构建产物的无密钥 Web 冒烟测试则通过组装后的客户端固定折叠与恢复行为。

-
-## Problem
-
-`dsh web` serves each web-client plugin's bundle from `GET /plugins/<id>/client.js`, resolving the path from the package's `exports["./client"]` (`lib/client.js`). Those bundles are produced only by the root `pnpm run build` (`tsc -b` then the per-package `tsdown.client.ts` configs); the Vite `build:web` step builds the frontend shell alone. `demo:web` and the README's Web UI instructions ran only `build:web`, so on a checkout without a prior full build every plugin bundle 404s, the client loader marks every plugin failed, and the boot screen shows "Failed to load plugins". The frontend shell built fine, hiding the missing artifact behind a runtime browser failure.
-
-## Decision
-
-`demo:web` runs `npm run build` before `npm run build:web`, so the plugin `lib/client.js` bundles exist before `dsh web` serves them. The README's Web UI section runs `pnpm run build && pnpm run build:web` for the installed `~/.dsh/source` checkout, which the installer never builds.
-
-## Verification
-
-After the full build, all eight `/plugins/<id>/client.js` endpoints return 200 and a headless Chromium load of `http://127.0.0.1:3080` renders the shell with no "Failed to load plugins" state.
-
-## Alternatives considered
-
-**Build the bundles inside `dsh web` at startup.** The app runs from source via tsx and owns no build step; folding an artifact build into the server boot crosses the source/artifact separation and slows every launch.
-
-**Widen the tsdown root config to emit client bundles from `pnpm run build:web`.** `build:web` is the Vite frontend build; the client bundles are a separate tsdown pass over `lib/types`. Merging the two conflates the shell build with the package build and still leaves the root `build` as the only producer.
-
-## Consequences
-
-`demo:web` now pays the full `tsc -b && tsdown` cost on every invocation instead of only the Vite build. That is the price of a runnable web demo from a clean tree; a caller who already built can invoke `dsh web` directly.

-Archived: 2026-07-26
-
-[English](2026-07-23-demo-web-builds-client-bundles.md) | 中文
-
-## Problem
-
-`dsh web` 通过 `GET /plugins/<id>/client.js` 提供每个 web 客户端插件的打包产物，其路径由包的 `exports["./client"]`（`lib/client.js`）解析得到。这些打包产物只由根目录的 `pnpm run build`（先 `tsc -b`，再执行各包的 `tsdown.client.ts` 配置）生成；Vite 的 `build:web` 步骤只构建前端外壳。`demo:web` 与 README 的 Web UI 说明只运行了 `build:web`，因此在未预先完整构建的检出上，每个插件的打包产物都返回 404，客户端 loader 将所有插件标记为失败，启动界面显示 "Failed to load plugins"。前端外壳能正常构建，把缺失的产物掩藏在浏览器运行时的失败背后。
-
-## Decision
-
-`demo:web` 在 `npm run build:web` 之前先运行 `npm run build`，使插件的 `lib/client.js` 打包产物在 `dsh web` 提供它们之前已经存在。README 的 Web UI 小节针对已安装的 `~/.dsh/source` 检出运行 `pnpm run build && pnpm run build:web`，因为安装器从不构建它。
-
-## Verification
-
-完整构建后，全部八个 `/plugins/<id>/client.js` 端点均返回 200，无头 Chromium 加载 `http://127.0.0.1:3080` 能渲染出外壳，不再出现 "Failed to load plugins" 状态。
-
-## Alternatives considered
-
-**在 `dsh web` 启动时构建打包产物。** 该应用通过 tsx 从源码运行，本身没有构建步骤；把产物构建塞进服务器启动流程会越过源码与产物的分离，并拖慢每次启动。
-
-**扩大 tsdown 根配置，使 `pnpm run build:web` 也产出客户端打包产物。** `build:web` 是 Vite 前端构建；客户端打包产物是对 `lib/types` 的另一趟独立 tsdown 处理。把两者合并会混淆外壳构建与包构建，而且根目录的 `build` 仍是唯一的产出者。
-
-## Consequences
-
-`demo:web` 现在每次调用都要付出完整的 `tsc -b && tsdown` 代价，而不再只是 Vite 构建。这是从干净的代码树运行 web 演示所要付出的代价；已经完成构建的调用方可以直接调用 `dsh web`。

-English | [中文](2026-07-23-thinking-row-disclosure-target.zh.md)
-
-## Problem
-
-A collapsed reasoning entry presents `Think` and its one-line reasoning summary as one visual row, but an icon-only disclosure control leaves both visible labels inert. Applying title expansion to every tool row would instead break the generic tool-row contract, where the row opens details and only the leading control expands arguments.
-
-## Decision
-
-`ToolRow` exposes the opt-in `expandOnRowClick` policy. `ThinkRow` enables it so the title and reasoning summary form one accessible disclosure target; pointer clicks, Enter, and Space toggle the same component-local expanded state. Tool rows that do not opt in retain row-to-details selection and leading-control argument expansion.
-
-## Verification
-
-The component spec pins both Think click targets and the unchanged generic tool-row handoff. The keyless browser fixture loads the real sidebar and conversation bundles, opens an authored reasoning session, clicks the summary and title, and checks the disclosure state and expanded body.
-
-## Alternatives considered
-
-**Expand every tool row from its title.** Generic tool rows use row clicks for details selection, so sharing this behavior would conflate two controls.
-
-**Keep icon-only disclosure.** The smallest hit target remains disconnected from the labels that describe the hidden content.
-
-**Render separate title and summary buttons.** Two controls for one expanded state add duplicate focus stops and ambiguous semantics.
-
-## Consequences
-
-Thinking rows gain a larger pointer target and keyboard disclosure semantics without changing other tool interactions. The generic row component carries one optional policy because disclosure ownership differs between reasoning and tool calls.

-## 问题
-
-折叠的推理（reasoning）条目在同一视觉行中呈现 `Think` 和单行推理摘要，但仅图标可展开会让两个可见标签都无法交互。若让所有工具行均可通过标题展开，又会破坏通用工具行的契约：整行负责打开详情，只有前导控件负责展开参数。
-
-## 决策
-
-`ToolRow` 提供显式启用的 `expandOnRowClick` 策略。`ThinkRow` 启用该策略，让标题和推理摘要组成单一且无障碍的展开目标；鼠标点击、Enter 和 Space 都切换同一个组件本地展开状态。未启用该策略的工具行仍由整行完成详情选择，由前导控件展开参数。
-
-## 验证
-
-组件测试固定两个 Think 点击目标以及未改变的通用工具行交接行为。无密钥浏览器 fixture（测试前置数据）加载真实的侧边栏与会话 bundle，打开包含推理内容的既定会话，点击摘要与标题，并检查展开状态和展开后的正文。

-
-English | [中文](2026-07-23-tui-generic-card-markdown.zh.md)
-
-## Problem
-
-Tool presenters can put Markdown in generic-card content, including fenced `console` output used for background-task acknowledgements and execution errors. Rendering that content as plain text exposes the fence markers and diverges from assistant and user content in the same transcript.
-
-## Decision
-
-The TUI renders generic-card result content with its shared Markdown theme before applying the card's head-and-tail line limit. Terminal and diff cards retain their specialized plain-text renderers, and generic-card raw input remains literal because it represents tool arguments rather than presenter-authored prose.
-
-The shared theme hides fence syntax, retains the optional language label, and colors the fenced body as code. Rendering precedes truncation so collapsed-card line counts and boundaries describe the visible terminal rows rather than Markdown source rows.
-
-## Alternatives considered
-
-**Strip fences in the Bash presenter.** This would fix one producer while leaving generic-card Markdown from other tools unrendered and would make the presenter depend on TUI behavior.
-
-**Render every tool card as Markdown.** Terminal output and diffs have dedicated formatting and may contain Markdown punctuation that must remain literal.
-
-**Apply the collapsed-card limit before Markdown rendering.** Source-line truncation can split a fenced block and makes the visible line count differ from the count used by the card.
-
-## Consequences
-
-Generic tool cards use the same Markdown vocabulary and sanitization path as conversation content. Markdown punctuation in a generic card is interpreted rather than always displayed literally; tools that require literal terminal output use the terminal card intent.

-The focused TUI test pins hidden fences, retained language labels, and body text. The keyless terminal-state snapshot covers the behavior through an assembled TUI transcript.

-TUI 先用共享的 Markdown 主题渲染通用卡片的结果内容，再应用卡片的头尾行数限制。终端卡片和 diff 卡片保留各自专门的纯文本渲染器；通用卡片的原始输入仍按字面显示，因为它代表的是工具参数，而非展示器撰写的行文。
-
-共享主题隐藏围栏语法，保留可选的语言标签，并将围栏正文按代码配色。渲染先于截断执行，因此收起状态卡片的行数和边界描述的是可见的终端行，而非 Markdown 源文本行。

-## Alternatives considered

-**在 Bash 展示器中剥除围栏。**这只修复一个生产方，其他工具产生的通用卡片 Markdown 仍不会被渲染，还会让展示器依赖 TUI 的行为。

-# Agent Note: TUI presents a reason for every turn-end kind
-
-Status: implemented
-Archived: 2026-08-04
-
-English | [中文](2026-07-24-tui-turn-end-stop-reason-notices.zh.md)
-
-## Problem
-
-The TUI rendered transcript notices for `error`, `aborted`, `max-tokens`, `rejected`, and `interrupted` turn ends, but a `disposed` turn end and any plugin-added `TurnEndReasonMap` kind rendered nothing. When such a turn ended — live or replayed from a persisted log — the agent stopped working with no visible reason, breaking the product expectation that every stop is explained to the user.
-
-## Decision
-
-The `turn/end` case in `packages/ui/tui/src/index.ts` switches on the reason's discriminant and covers every kind: `completed` stays silent because the settled assistant message and its `Completed` timing header already present that outcome; `disposed` appends `Turn stopped: the agent was disposed.`; and the merge-extensible default appends `Turn ended: <kind>.` so an unknown plugin-added outcome still names why the agent stopped. All other kinds keep their existing notices.
-
-## Alternatives considered
-
-**A notice for `completed` turns too.** Rejected as noise: every ordinary response would gain a redundant line, and the assistant message plus its frozen timing header already mark the completion.
-
-**Suppressing the `disposed` turn-end notice live because `agent/disposed` also appends `Agent "<id>" was disposed.`** Rejected: the two notices state different facts (this turn was cut short vs. the agent is gone), and the turn-end notice is the only one that survives replay of a persisted log, where the live `agent/disposed` emission does not recur.
-
-**Keeping the default branch silent (the prior behavior).** Rejected: a merge-extensible kind unknown to the TUI is exactly the case where the user has no other way to learn why the agent stopped.
-
-## Consequences
-
- A turn never ends without a user-visible reason in the TUI: every non-`completed` `turn/end` kind appends a transcript notice, including unknown plugin-added kinds by name.
- Live disposal during a running turn shows two notices (the turn-end notice plus `agent/disposed`); a replayed log shows the turn-end notice alone.

-## 问题
-
-TUI 会为 `error`、`aborted`、`max-tokens`、`rejected`、`interrupted` 这几种轮次结束渲染 transcript（文本记录）通知，但 `disposed` 轮次结束和任何插件新增的 `TurnEndReasonMap` kind 不渲染任何内容。此类轮次结束时，无论实时发生还是从持久化日志回放，agent（智能体）都会在没有任何可见原因的情况下停止工作，违背了「每次停止都要向用户解释」的产品预期。
-
-## 决策
-
-`packages/ui/tui/src/index.ts` 中的 `turn/end` 分支按 reason 的判别字段做 switch，覆盖每一种 kind：`completed` 保持沉默，因为已定稿的助手消息及其 `Completed` 计时头部已经呈现了这一结果；`disposed` 追加 `Turn stopped: the agent was disposed.`；merge 扩展的 default 分支追加 `Turn ended: <kind>.`，让未知的插件新增结果仍能点明 agent 停止的原因。其余各 kind 保留现有通知。
-
-## 备选方案
-
-**为 `completed` 轮次也加一条通知。** 否决，属于噪音：每次普通响应都会平添一行冗余内容，而助手消息加上已冻结的计时头部本就标示了完成。
-
-**因为 `agent/disposed` 也会追加 `Agent "<id>" was disposed.`，就在实时场景下抑制 `disposed` 轮次结束通知。** 否决：两条通知陈述的是不同事实（前者说明这一轮被中途截断，后者说明 agent 已不复存在），而且只有轮次结束通知在回放持久化日志时得以保留，实时发出的 `agent/disposed` 不会在回放中重现。
-
-**让 default 分支保持沉默（沿用先前行为）。** 否决：TUI 不认识的 merge 扩展 kind，恰恰是用户没有其他途径得知 agent 为何停止的情形。
-
-## 后果
-
- 在 TUI 中，轮次结束永远不会缺少用户可见的原因：每种非 `completed` 的 `turn/end` kind 都会追加一条 transcript 通知，未知的插件新增 kind 也会按名称列明。
- 轮次运行期间实时 dispose（资源释放）会显示两条通知（轮次结束通知加上 `agent/disposed`）；回放日志则只显示轮次结束通知。
- `errors-and-help` 快照把 `disposed` 通知和未知 kind 通知连同现有的失败与中断通知一并固定下来。

-## Problem
-
-The hero composer ("Let's start building") is a controlled textarea whose value is the frontend Session Intent's retained prompt, read from the sessions **list** snapshot (`EmptyState` binds `intent.prompt` via `useSessions`). Typing routed through `SessionManager.updateIntent → Session.updatePendingPrompt`, which flushes the **Session's own** notifier synchronously — but the list snapshot the composer actually renders from only heard about the change through the intent watch subscription in `startIntent`, which calls `markDirty()`, a microtask-deferred flush.
-
-A deferred echo violates the controlled-input contract documented on the Notifier (see the [web client architecture note](../architecture/2026-07-19-gui-web-client-architecture.md)): React compares the DOM value against the still-stale snapshot during the same tick as `onChange` and rolls the textarea back. With plain typing this shows as caret jumps; with an IME it corrupts input — every composition update gets rolled back and re-applied against a stale value, so typing Pinyin "nihao" commits fragments like "nnini hni hani hao你好". The resident composer (`ConversationRoot`) was not affected: its draft lives in the chat store (sync flush) or comes from `updateSessionPrompt`, which reads the Session snapshot directly rather than the list projection.
-
-## Decision
-
-`SessionManager.updateIntent` calls `this.notifier.notifyNow()` after `updatePendingPrompt`, flushing the list snapshot in the same tick as the change event. This matches the Notifier's channel rule: a direct echo of a user gesture whose controlled input renders from this snapshot uses `notifyNow`; the intent watch keeps `markDirty` for every other (async) intent transition.
-
-## Alternatives considered
-
-**Change the intent watch callback in `startIntent` to `notifyNow`.** Wrong channel for that seam: the watch also fires on frame-driven Session changes (publication, send phases), and the architecture note bans `notifyNow` for frame-driven sources because it collapses batching.
-
-**Have `EmptyState` read the prompt from the Session snapshot instead of the list.** Restructures the slot contract (EmptyState is deliberately bound to the standard `useSessions` feed and has no session scope yet — the frontend Session is page-local) for no gain over flushing the projection it already reads.
-
-**Suppress the rollback in `InputBar` with local uncontrolled state.** Hides the symptom, forfeits the single-source-of-truth draft (the retained prompt must survive workspace retargeting and send/retry), and leaves every other list-snapshot-controlled input exposed.
-
-## Consequences
-
-Typing in the hero composer, IME composition included, echoes synchronously. `updateIntent` on a no-intent state stays a no-op with no notification. The web workspace-flow snapshot's composer helper now asserts the same-tick echo instead of waiting for it, so a regression to a deferred echo fails the keyless snapshot gate; a runtime unit test pins the same contract at the manager seam.

-## Problem
-
-hero composer（「Let's start building」）是一个受控（controlled）的 textarea，它的值取自前端 Session Intent 保留下来的提示词，读自会话**列表**快照（`EmptyState` 通过 `useSessions` 绑定 `intent.prompt`）。输入经由 `SessionManager.updateIntent → Session.updatePendingPrompt`，后者会同步刷新 **Session 自身的** notifier——但 composer 实际渲染所依据的那份列表快照，只能通过 `startIntent` 中的 intent watch 订阅得知这次变更，而该订阅调用的是 `markDirty()`，即一次延迟到微任务的刷新。
-
-延迟的回显违反了 Notifier 上所记录的受控输入契约（见 [web 客户端架构笔记](../architecture/2026-07-19-gui-web-client-architecture.md)）：React 在与 `onChange` 相同的 tick 内，把 DOM 值与仍然陈旧的快照相比对，随后把 textarea 回滚。普通输入时，这表现为光标跳动；使用输入法（IME）时，它会损坏输入——每一次 composition 更新都会被回滚，并针对陈旧的值重新应用，因此输入拼音「nihao」会提交出类似「nnini hni hani hao你好」这样的片段。resident composer（`ConversationRoot`）不受影响：它的草稿存放在 chat store 中（同步刷新），或来自 `updateSessionPrompt`，后者直接读取 Session 快照，而不是列表投影。
-
-## Decision
-
-`SessionManager.updateIntent` 在 `updatePendingPrompt` 之后调用 `this.notifier.notifyNow()`，从而在与变更事件相同的 tick 内刷新列表快照。这符合 Notifier 的通道规则：当某个用户手势的受控输入正是从该快照渲染时，对它的直接回显使用 `notifyNow`；而 intent watch 对其余所有（异步的）intent 状态转换仍保留 `markDirty`。
-
-## Alternatives considered
-
-**把 `startIntent` 中的 intent watch 回调改为 `notifyNow`。** 对那个 seam 而言是错误的通道：该 watch 也会在帧驱动的 Session 变更（发布、发送阶段）时触发，而架构笔记禁止对帧驱动的来源使用 `notifyNow`，因为那会瓦解批处理。
-
-**让 `EmptyState` 从 Session 快照而非列表读取提示词。** 这会重构槽位契约（EmptyState 有意绑定到标准的 `useSessions` 数据源，且尚无 session 作用域——前端 Session 是页面本地的），相比刷新它本就读取的那份投影并无收益。
-
-**在 `InputBar` 中用本地的非受控状态抑制回滚。** 这只是掩盖症状，放弃了单一真源的草稿（保留下来的提示词必须在工作区重定向以及发送／重试后依然存在），并让其余每一个由列表快照控制的输入都暴露在同一问题之下。
-
-## Consequences
-
-在 hero composer 中输入（包括输入法 composition 在内）会同步回显。在无 intent 的状态上调用 `updateIntent` 仍是一次空操作，不发出任何通知。web workspace-flow 快照的 composer 辅助函数现在断言的是同一 tick 内的回显，而不是等待它，因此一旦回退成延迟回显，就会让无密钥快照门禁失败；一个运行时单元测试在 manager 这一 seam 处钉住了同一份契约。

-# Agent Note: Question-composer option rows are scroll content, not the slack absorber
-
-Status: implemented
-Archived: 2026-08-07
-
-English | [中文](2026-07-27-question-composer-rows-do-not-shrink.zh.md)
-
-## Problem
-
-The question composer card is capped against the viewport (`max-height: min(60vh, 520px)`) and scrolls its option list, so the header and the footer actions stay reachable on long question batches. When the composer seat got short — a small window, or a short viewport with the details panel open — the option rows rendered on top of each other and on top of the question title.
-
-The cap was not the defect; the distribution of the shortfall was. `.options` is a `flex-direction: column` box whose children default to `flex-shrink: 1`, so under-allocation shrank the rows first instead of overflowing the scroll container. A row shrank to its `min-height: 42px` while `.optionCopy` kept the taller intrinsic height its wrapped copy needs (two lines for an option with a description). With `align-items: center`, the copy is then centered on a box shorter than itself and paints outside the row's border box in both directions — over the title above and the next row below. Measured on the shipped client at 900x440: 6.5px of copy outside the row box, growing to 10px at 380px tall, while `.options` reported `scrollHeight === clientHeight` and therefore never offered a scrollbar.
-
-Only rows whose copy wraps can reproduce it. A row whose copy fits on one line has slack between its content and its 42px minimum, so shrinking it stays invisible — which is why the pre-existing e2e fixture (options `Blue`/`Green`, no descriptions) rendered correctly at every size.
-
-## Decision
-
-`.option` and `.custom` declare `flex-shrink: 0`.
-
-The rows are the scroll content of a capped card; the card's overflow belongs to `.options`, which already owns `overflow-y: auto` and `min-height: 0`. Pinning the children makes the shortfall reach that scroll container instead of being absorbed by the rows, which is the behavior the cap was designed for. The alternative — letting rows shrink but keeping the copy inside them — would require clipping or ellipsizing option descriptions at exactly the sizes where the user most needs to read them.
-
-`.header` and `.footer` already carried `flex-shrink: 0` for the same reason at the card level; the option list's children were the missing half of that rule.
-
-## Alternatives considered
-
-**Clip or ellipsize the copy inside a shrunk row (`overflow: hidden` on `.option`).** This removes the overlap with one declaration and no layout rethink. Rejected because it trades a visible defect for a silent one: the row keeps its 42px, and the second line of an option description simply disappears at exactly the sizes where the card is tightest. The description is decision-relevant content, not decoration.
-
-**Drop `align-items: center` for `align-items: flex-start`.** The copy would grow downward only, so it would no longer paint over the title above. It does not fix anything: a shrunk row still overflows onto the row below, and the fix would silently change the vertical alignment of every option row at every size, including the common one.
-
-**Remove the card's `max-height` cap so nothing is ever squeezed.** No shortfall means no distribution problem. Rejected because the cap is what keeps the header and the footer actions on screen for a long question batch; removing it reintroduces the failure the cap exists to prevent (the composer seat is a fixed-height conversation column with `overflow: hidden`, so an uncapped card loses its own submit button instead).
-
-**Cap the wrapped copy at one line (`white-space: nowrap` plus ellipsis on `.description`).** Rows would never wrap, so they could never overflow when shrunk. Rejected for the same reason as clipping, plus it degrades the wide-viewport rendering — where there is ample room — to fix a narrow-viewport defect.
-
-## Consequences
-
- A squeezed composer scrolls its option list instead of overlapping it: at 900x380 the list reports `scrollHeight` 200 against `clientHeight` 114 and offers a scrollbar, where before it reported them equal and offered none.
- Option rows keep their full wrapped copy at every viewport size. Nothing is clipped or ellipsized, and the wide-viewport rendering is unchanged (the rule only takes effect when the flex box is under-allocated).
- The card now reaches its scroll state sooner, since the shortfall is no longer partly absorbed by the rows. That is the intended behavior of the cap, and it means a short seat shows a scrollbar in cases that previously showed a silently mis-painted list.
- The scenario's recorded question is longer than it needs to be for the round trip it primarily tests. That cost is deliberate: the layout invariant is unfalsifiable without wrapping copy, and a second fixture for one CSS rule would be worse.
-
-## Verification
-
-The web e2e composer scenario asserts the invariant on the live composer at three squeezed seat heights (900x520 / 440 / 380): every option row's children stay inside the row's border box. Two guards keep the assertion from holding vacuously — at least one row must be wrapped (the only shape that overflows) and `.options` must actually be scrolling (proof the seat is genuinely capped). The scenario's recorded question now carries long option descriptions for exactly that reason; without wrapping copy the assertion cannot fail.
-
-Confirmed both directions against the built client: with `flex-shrink: 0` reverted the scenario fails (`scrolls: false`, 6.5px spill), and with it restored it passes. A standalone geometry sweep over 340 viewport sizes (420-1600 x 320-960) went from 86 sizes with copy outside a row box to zero.
-
-The assertion is replay-only: record mode must reach the fixture write rather than aborting on layout. Note that the composer ships as a client-module bundle, so `pnpm run build:web` alone does not pick up a change to `QuestionComposer.module.css` — the package build must run for the browser lane to see it.
-
-Reproducing the shortfall requires a short viewport, not a short container. The cap is `min(60vh, 520px)`, so shrinking the conversation column below the card's own height clips the card without under-allocating it — the rows keep their full height and nothing spills. Anything demonstrating or measuring this defect outside the e2e scenario has to change the viewport.
-
-A stale `lib/` makes the browser lane assert against an older client than the tree, and a `pnpm run build` that fails part-way leaves exactly that: the packages built before the failure are current, the rest are not. Refreshing a golden in that state records the older client's surface. Confirm the build exited zero before capturing, and note that untracked directories under `packages/` are compiled too — a leftover from another branch can fail the build for reasons the diff does not explain.

-# Agent Note: 提问 composer 的选项行是滚动内容，而非空间不足时的吸收方

-[English](2026-07-27-question-composer-rows-do-not-shrink.md) | 中文

-## 问题
-
-提问 composer 的卡片会按视口设上限（`max-height: min(60vh, 520px)`），并让选项列表自行滚动，这样在成批提问时头部和底部操作按钮始终可达。但当 composer 的可用区域变矮时（窗口较小，或视口偏矮且详情面板处于展开状态），选项行会互相叠在一起，也会叠到问题标题上。
-
-缺陷不在这个高度上限，而在高度不足时由谁来吸收。`.options` 是一个 `flex-direction: column` 的盒子，其子元素默认取 `flex-shrink: 1`，因此空间不足时首先被压缩的是各个选项行，而不是让滚动容器产生溢出。一行会被压到它的 `min-height: 42px`，而 `.optionCopy` 仍保持文案折行后所需的更大固有高度（带描述的选项会占两行）。由于 `align-items: center`，文案于是以一个比自身更矮的盒子为基准居中，并向上下两个方向画到该行边框盒之外——向上盖住标题，向下盖住下一行。在实际发布的客户端上于 900x440 处实测：文案有 6.5px 落在行盒之外，视口高度降到 380px 时增至 10px，而 `.options` 报告的 `scrollHeight` 等于 `clientHeight`，因此始终不会给出滚动条。
-
-只有文案会折行的选项行才能复现该问题。文案单行即可容纳的行，其内容与 42px 最小高度之间尚有余量，被压缩也看不出来——这正是既有 e2e fixture（测试前置数据）（选项为 `Blue`／`Green`，无描述）在任何尺寸下都渲染正常的原因。
-
-## 决策
-
-`.option` 与 `.custom` 声明 `flex-shrink: 0`。
-
-在设有高度上限的卡片中，这些行是滚动内容；卡片的溢出归 `.options` 承担，它本就持有 `overflow-y: auto` 与 `min-height: 0`。把子元素固定住之后，高度不足会传导到那个滚动容器，而不再被行本身吸收，这正是该高度上限设计时想要的行为。另一种做法是允许行被压缩，但把文案约束在行内，那就必须在用户最需要阅读选项描述的尺寸上对其做裁剪或省略号处理。
-
-`.header` 与 `.footer` 出于同样的原因，已在卡片层级带有 `flex-shrink: 0`；选项列表的子元素正是这条规则缺失的另一半。
-
-## 曾考虑的替代方案
-
-**在被压缩的行内裁剪文案或加省略号（对 `.option` 设 `overflow: hidden`）。** 这样一条声明就能消除重叠，且不必重新考虑布局。之所以否决：它把一个可见缺陷换成了一个无声缺陷——行仍保持 42px，而选项描述的第二行会在卡片最紧张的那些尺寸上直接消失。描述属于影响决策的内容，不是装饰。
-
-**把 `align-items: center` 改为 `align-items: flex-start`。** 文案就只会向下生长，因此不再向上盖住标题。但这什么也没修好：被压缩的行依然会溢出到下一行上，而且这一改动会在所有尺寸下（包括常见尺寸）无声改变每个选项行的垂直对齐。
-
-**移除卡片的 `max-height` 上限，使其永远不会被压缩。** 没有高度不足，就没有分配问题。之所以否决：正是这个上限保证成批提问时头部和底部操作按钮留在屏幕内；移除它会重新引入该上限本就为之存在的失败（composer 所处的容器是一个固定高度、`overflow: hidden` 的会话列，因此不设上限的卡片会连自己的提交按钮一起丢掉）。
-
-**把折行文案限制为单行（对 `.description` 设 `white-space: nowrap` 加省略号）。** 行永远不会折行，因此被压缩时也永远不会溢出。否决理由与裁剪相同，此外它还为了修一个窄视口缺陷，而牺牲了空间充裕的宽视口渲染效果。
-
-## 后果
-
- 被压缩的 composer 会滚动其选项列表，而不是让选项行互相重叠：在 900x380 处，该列表报告 `scrollHeight` 为 200、`clientHeight` 为 114，并给出滚动条；此前两者相等，不给滚动条。
- 选项行在任何视口尺寸下都保留完整的折行文案。不裁剪、不加省略号，宽视口下的渲染保持不变（该规则仅在 flex 盒子空间不足时才生效）。
- 由于高度不足不再被行部分吸收，卡片现在更早进入滚动状态。这正是该高度上限想要的行为，也意味着在此前只会无声画错列表的情形下，较矮的可用区域现在会显示滚动条。
- 该场景录制的问题，比它主要测试的那次往返所需的长度更长。这个代价是有意付出的：没有折行文案，该布局不变式无法被证伪，而为一条 CSS 规则再加一份 fixture 会更糟。
-
-## 验证
-
-Web e2e 的 composer 场景会在三个受挤压的可用区域高度下（900x520／440／380），在实际运行的 composer 上断言该不变式：每个选项行的子元素都留在该行的边框盒之内。两道守卫防止该断言空洞地成立——必须至少有一行处于折行状态（这是唯一会溢出的形态），且 `.options` 必须确实处在滚动状态（证明可用区域确实受到了高度上限约束）。该场景录制的问题现在带有较长的选项描述，正是为此；没有折行文案，这条断言不可能失败。
-
-在构建产物客户端上双向确认过：撤销 `flex-shrink: 0` 后该场景失败（`scrolls: false`，6.5px 溢出），恢复后通过。一次覆盖 340 种视口尺寸（420-1600 x 320-960）的独立几何遍历，从 86 种尺寸存在文案落在行盒之外，降到 0 种。
-
-该断言仅在回放模式下执行：录制模式必须走到写入 fixture 那一步，而不是在布局检查处中断。另需注意，composer 以客户端模块包的形式发布，因此单跑 `pnpm run build:web` 不会带上对 `QuestionComposer.module.css` 的改动——必须执行包构建，浏览器测试通道才能看到它。
-
-要复现这种空间不足，需要的是矮视口，而不是矮容器。高度上限为 `min(60vh, 520px)`，因此把会话列压到比卡片自身高度更矮，只会裁剪卡片，而不会让它空间不足——各行仍保持完整高度，也不会有任何溢出。凡是在 e2e 场景之外演示或测量该缺陷的手段，都必须改变视口。
-
-`lib/` 陈旧会让浏览器测试通道对着一个比工作树更旧的客户端做断言，而中途失败的 `pnpm run build` 留下的正是这种状态：失败之前构建的那些包是新的，其余不是。在这种状态下刷新预期输出，记录下来的是旧客户端的界面。抓取之前先确认构建以 0 退出；另需注意 `packages/` 下的未跟踪目录同样会被编译——来自另一个分支的遗留物可能以 diff 无法解释的原因让构建失败。

-## Problem
-
-A tool card's title, description, cwd, and pending `$ <command>` echo are each one logical row. The bash tool sets the card title (and description) directly from the model's command and description, which for a multi-line bash script contain real newlines. These fields were escaped with `displayText`, which deliberately preserves `\n` as structural layout. A multi-line title therefore broke onto extra terminal rows that the card's line accounting did not reserve, so the title's later lines overwrote the description, the output, or the editor's steering hint — the card rendered as garbled, overlapping text. Removing the gutter bar (see the [copyable-transcript note](../simplification/2026-07-27-copyable-transcript-no-gutter-bar.md)) made the collision visible because those rows no longer sat behind a per-line prefix.
-
-## Decision
-
-Single-row card fields use `displayInlineText` (which escapes `\n` to the literal `\x0a`) instead of `displayText`: the card title, the terminal-card `description` and `cwd` meta rows, and the pending `$ <command>` echo. Each stays on exactly one row, so a multi-line command can no longer break rows and collide with adjacent lines. Genuinely multi-line fields — captured command output and the `contentText` result body — keep `displayText` plus `split('\n')`, because those legitimately occupy multiple rows.
-
-## Alternatives considered
-
- **Strip newlines from the presenter output** (in the bash tool) — hides the model's real command shape from any consumer of the view, and pushes a UI concern into the tool. The escape belongs at the single-row render site.
- **Let the title wrap to multiple rows deliberately** — a card title is a one-line identity; a wrapped multi-line title still collides with the following meta rows unless the whole card is re-laid-out, and it bloats the transcript.
-
-## Consequences
-
- Multi-line bash commands render as a single inline title (`S=/tmp\x0aecho …`); the description, output, and exit rows below stay intact. Verified live in tmux for both the pending (`◌`) and completed (`✓`) states.
- A `multilineTerminal` tool-card case in `tui.spec.ts` asserts the inline-escaped form appears for a newline-bearing title and description.

-## Problem
-
-工具卡片的标题、描述、cwd 以及待执行的 `$ <command>` 回显各自都是一个逻辑行。bash 工具直接用模型给出的命令与描述来设置卡片标题（和描述），而对于多行 bash 脚本，这些内容包含真实换行。这些字段此前用 `displayText` 转义，而 `displayText` 会刻意保留 `\n` 作为结构性布局。于是多行标题会换到卡片行数核算未预留的额外终端行上，标题后续的行便覆盖了描述、输出，或编辑器的 steering 提示——卡片渲染成互相重叠的乱码文本。移除 gutter bar（见[可复制 transcript 的 note](../simplification/2026-07-27-copyable-transcript-no-gutter-bar.md)）后，这些行不再位于逐行前缀之后，因而暴露了这一冲突。
-
-## Decision
-
-单行卡片字段改用 `displayInlineText`（将 `\n` 转义为字面量 `\x0a`）而非 `displayText`：包括卡片标题、terminal 卡片的 `description` 与 `cwd` 元数据行，以及待执行的 `$ <command>` 回显。每个字段都严格保持在一行内，因此多行命令不再会换行并与相邻行冲突。真正多行的字段——捕获的命令输出与 `contentText` 结果正文——仍保留 `displayText` 加 `split('\n')`，因为它们本就应占据多行。
-
-## Alternatives considered
-
- **在 presenter 输出中剥除换行**（在 bash 工具里）—— 会对该视图的所有消费方隐藏模型真实的命令形态，并把 UI 关注点塞进工具。转义应发生在单行渲染处。
- **让标题刻意换到多行** —— 卡片标题是一行式身份标识；除非重排整个卡片，多行标题仍会与其后的元数据行冲突，还会让 transcript 膨胀。

-# Agent Note: TUI diff card dropped the duplicated file path

-English | [中文](2026-07-27-tui-diff-card-redundant-path-header.zh.md)
-
-## Problem
-
-The `edit` and `write` tool cards printed the target path twice. Each tool's `presentCall`/`presentResult` returns a diff card whose title is `Edit <path>`/`Write <path>` and whose single `FileDiff` carries the same `path`. The TUI's `diffLines` unconditionally rendered `palette.bold(diff.path)` as a per-file header, so a one-file edit rendered:
-
-```
-✓ Edit src/foo.ts
-src/foo.ts
- old
-+ new
-```
-
-The existing snapshot fixture hid the bug: it titled the edit card `Edit renderer` (no path) and gave the result two diffs, so the title never matched a diff path and the header never looked redundant.
-
-## Decision
-
-`diffLines` takes a `showPath` flag; `ToolCardComponent.renderBody` suppresses the per-file header for a diff card when there is exactly one diff and the effective card title (`resultView?.title ?? callView.title`) already contains that diff's path. Multi-file diff cards keep every per-file header. An empty or blank diff path collapses under the same `String.includes` check, which is the intended noise removal.
-
-The suppression lives in the TUI renderer, not in each tool's presenter, because the redundancy is a presentation concern shared by every current and future single-file diff card; the tools keep emitting the path in both the title and the diff so non-TUI consumers still get it.
-
-## Alternatives considered
-
- Drop the path from the `edit`/`write` card titles. Rejected: the title is the scannable summary line; removing the path weakens it, and it would have to be repeated per tool.
- Always drop the per-file header. Rejected: multi-file result diffs (and any future multi-file diff card) genuinely need per-file headers.
-
-## Consequences
-
-The heuristic is a substring match, so a title that happens to contain a single diff's path suppresses the header even if the match is incidental; for the real producers the title is exactly `Verb <path>`, so this is correct in practice. The snapshot `edit` fixture now mirrors production: one diff whose path the title names, proving the header is dropped, while multi-file header retention is covered by the `tui.spec.ts` `edit` fixture (`a.txt`/`b.txt` under an `Edit files` title).
-
-## Testing
-
-`tui.spec.ts` adds a focused case asserting the path appears exactly once for a single-diff card titled `Edit src/only.ts`. The `advanced-cards-*` keyless snapshots re-recorded to show the title line immediately followed by the diff body with no repeated path header.

-[English](2026-07-27-tui-diff-card-redundant-path-header.md) | 中文
-
-## Problem
-
-`edit` 与 `write` 工具卡片会把目标路径打印两次。两者的 `presentCall`/`presentResult` 返回的 diff 卡片，标题为 `Edit <path>`/`Write <path>`，而其唯一的 `FileDiff` 又携带相同的 `path`。TUI 的 `diffLines` 无条件地将 `palette.bold(diff.path)` 渲染为每文件的表头，因此单文件编辑会渲染成：
-
-```
-✓ Edit src/foo.ts
-src/foo.ts
- old
-+ new
-```
-
-既有的快照 fixture 掩盖了这个问题：它把编辑卡片标题设为 `Edit renderer`（不含路径），并让结果包含两个 diff，于是标题从未与某个 diff 路径匹配，表头也就不显得冗余。
-
-## Decision
-
-`diffLines` 新增 `showPath` 参数；当一个 diff 卡片只有一个 diff、且生效标题（`resultView?.title ?? callView.title`）已包含该 diff 的路径时，`ToolCardComponent.renderBody` 抑制每文件表头。多文件 diff 卡片保留全部每文件表头。空白或空路径同样落入这条 `String.includes` 判定之下，这正是有意去除的噪声。
-
-抑制逻辑放在 TUI 渲染层，而非各工具的 present 方法中，因为这种冗余是所有当前及未来单文件 diff 卡片共有的展示问题；工具仍在标题和 diff 中同时给出路径，从而非 TUI 消费方依旧能拿到它。
-
-## Alternatives considered
-
- 从 `edit`/`write` 卡片标题中去掉路径。已否决：标题是可快速扫读的摘要行，去掉路径会削弱它，而且需要在每个工具里重复处理。
- 一律去掉每文件表头。已否决：多文件结果 diff（以及未来任何多文件 diff 卡片）确实需要每文件表头。
-
-## Consequences
-
-该启发式是子串匹配，因此若标题恰好包含某个单一 diff 的路径，即便是偶然匹配也会抑制表头；对真实的产出方而言标题恰为 `Verb <path>`，故在实践中是正确的。快照 `edit` fixture 现在与生产一致：单个 diff，其路径正是标题所命名，从而证明表头被去除；而多文件表头保留由 `tui.spec.ts` 的 `edit` fixture（`Edit files` 标题下的 `a.txt`/`b.txt`）覆盖。
-
-## Testing
-
-`tui.spec.ts` 新增一个聚焦用例，断言标题为 `Edit src/only.ts` 的单 diff 卡片中路径恰好出现一次。`advanced-cards-*` 无密钥快照已重新录制，展示标题行紧接 diff 正文、不再有重复的路径表头。

-# Agent Note: TUI step timing trails the step's last message

-Archived: 2026-08-04
-
-English | [中文](2026-07-27-tui-step-timing-trails-tool-cards.zh.md)
-
-## Problem
-
-The per-step timing summary (`Model wait … · Completed …`) was a child of the assistant message component, so it rendered directly under the assistant text. When a step drove tool calls, the tool cards were appended to the chat *after* the assistant message, leaving the timing line stranded above them — one message before the step's actual last output. The summary is meant to close a step, so on any tool-calling step it appeared in the wrong place.
-
-## Decision
-
-The timing summary is its own `StepTimingComponent`, no longer a child of `AssistantMessageComponent`. `StreamingAssistantComponent` owns one and exposes it as `timing`, but the renderer attaches it to the chat as a sibling that follows the assistant message. Whenever a `tool/call` or `tool/result` of the open step appends a card, `trailStreamingTiming()` moves the footer back to the tail of the chat, so it always trails the step's last message. On `step/end` the footer is completed in place — already at the tail — and stays pinned while the next step's output follows. `removeStreaming` and the reasoning-toggle rebuild detach and reattach the footer together with its streaming component.
-
-Event ordering makes this exact: within a step the loop appends `tool/call` and `tool/result` before `step/end`, so the footer is repositioned while `streaming` is still set, then frozen when the step ends.
-
-## Alternatives considered
-
-**Keep the timing inside the assistant message and reorder tool cards above it.** Rejected: tool cards belong after the assistant text that requested them; moving them above the assistant message to sit under the timing would misrepresent the transcript order.
-
-**Recompute a single trailing footer for the whole turn instead of one per step.** Rejected: a multi-step turn shows each step's own completed timing, and collapsing them would drop the per-step buckets the existing timing tests pin.
-
-**Reposition the footer from a `step/end`-only handler.** Rejected: tool cards render before `step/end`, so a footer moved only at step end would already be trailing but would not track a mid-step re-render, and the running (pre-completion) footer would still sit above the tool cards during streaming.
-
-## Consequences
-
- On a tool-calling step the timing summary renders below the tool cards, both while the turn runs and after it completes; the package snapshots (`untrusted-controls`, `cordis-tools-pending`, `advanced-cards-*`, `code-mode-pending`, `dynamic-workflow-pending`, `surface-before-compaction`) and the example transcripts (`todo-plan`, `bash-terminal-card`, `code-mode`, `parallel-file-reads`, `dynamic-workflow`, `cordis-dynamic-toolchain`, `code-mode-dispatch-spill`) pin the new order.
- A unit test asserts the completed timing appears after a step's tool output; it fails on the pre-fix ordering.

-Archived: 2026-08-04

-[English](2026-07-27-tui-step-timing-trails-tool-cards.md) | 中文
-
-## 问题
-
-每步的计时摘要（`Model wait … · Completed …`）原本是助手消息组件的子节点，因此直接渲染在助手文本下方。当某一步触发 tool call 时，tool card（工具卡片）会在助手消息*之后*追加到聊天区，使计时行被搁在它们上方——落在该步骤真正的最后一条输出之前一条消息处。该摘要本意是收束一个步骤，因此在任何含 tool call 的步骤上都出现在了错误的位置。
-
-## 决策
-
-计时摘要现在是独立的 `StepTimingComponent`，不再是 `AssistantMessageComponent` 的子节点。`StreamingAssistantComponent` 持有一个并以 `timing` 暴露它，但渲染器把它作为紧随助手消息之后的同级节点挂到聊天区。每当当前打开步骤的 `tool/call` 或 `tool/result` 追加一张卡片，`trailStreamingTiming()` 就把该页脚移回聊天区末尾，使它始终跟在该步骤的最后一条消息之后。在 `step/end` 时该页脚就地定稿——此时已在末尾——并在后续步骤的输出接续时保持钉住。`removeStreaming` 与推理开关重建会把该页脚连同其流式组件一起摘除并重新挂上。
-
-事件顺序让这一点精确成立：在一个步骤内，循环会先追加 `tool/call` 和 `tool/result`，再追加 `step/end`，因此页脚是在 `streaming` 仍被设置时重新定位的，随后在步骤结束时冻结。
-
-## 备选方案
-
-**把计时保留在助手消息内部，改为把 tool card 排到它上方。** 否决：tool card 应位于请求它们的助手文本之后；把它们移到助手消息上方以贴在计时下方，会歪曲 transcript（文本记录）的顺序。
-
-**为整个轮次重算一个末尾页脚，而非每步一个。** 否决：多步轮次会显示各步自己的完成计时，合并它们会丢掉现有计时测试所固定的每步分桶。
-
-**只在 `step/end` 处理器里重新定位页脚。** 否决：tool card 在 `step/end` 之前渲染，因此仅在步骤结束时移动的页脚虽已处于末尾，却无法跟踪步骤中途的重新渲染，而且流式过程中运行态（完成前）的页脚仍会落在 tool card 上方。
-
-## 后果
-
- 在含 tool call 的步骤上，计时摘要渲染在 tool card 下方，轮次运行期间与完成之后皆如此；相关包快照（`untrusted-controls`、`cordis-tools-pending`、`advanced-cards-*`、`code-mode-pending`、`dynamic-workflow-pending`、`surface-before-compaction`）与示例 transcript（`todo-plan`、`bash-terminal-card`、`code-mode`、`parallel-file-reads`、`dynamic-workflow`、`cordis-dynamic-toolchain`、`code-mode-dispatch-spill`）固定了新顺序。
- 一个单元测试断言完成计时出现在某步骤的工具输出之后；在修复前的顺序下它会失败。

-# Agent Note: Web conversation UI polish sweep

-English | [中文](2026-07-28-web-conversation-polish-sweep.zh.md)

-## Problem
-
-A design review of the web GUI's conversation surfaces found a batch of presentation defects: portal menus painted one frame at the wrong position before repositioning (visible open jump), the chat column split one tool run into several groups whenever a step message carried only tool-call heads, tool row summaries printed workspace-absolute paths that consumed most of the row, the running-row sweep was implemented as an alpha mask that dimmed the whole row, the hero workspace chip resurrected a deleted workspace's folder name from the session cwd, and the header showed a turns counter nobody asked for next to a 13px title.
-
-## Decision
-
-The sweep lands as presentation-layer changes only; nothing enters the session log.
-
- **Portal menus pre-render hidden and measure before paint.** The menu list mounts with `visibility: hidden` at (0,0), measures in `useLayoutEffect`, and becomes visible already at its final position. Menus keep 12px viewport clearance with internal scroll; workspace create actions pin in a non-scrolling footer.
- **The chat flow skips assistant nodes that render nothing.** A finalized assistant node whose blocks are only tool-call heads and blank text/reasoning is dropped from the flow derivation, so consecutive tool results merge into one group. Interrupted nodes always render (they carry the 已停止 marker).
- **Tool row summaries relativize workspace-rooted paths.** The session cwd threads through the toolview slot contract (`ToolRowOwnerProps.cwd`) and `toolRowModel` strips it from summaries that start with it; paths outside the workspace stay verbatim. Display-only — args and the log are untouched.
- **The running sweep is a glare-band overlay.** A fixed-width `::after` gradient band animates across the row (the deepsuite ShimmerText pattern), replacing the previous `mask-image` approach, in both ToolRow and the Bash toolview.
- **The hero workspace chip is a selector, not an echo.** With no live selection (cold start, or the workspace was deleted after the list settled) it shows a "Choose workspace" placeholder; the cwd-derived name only bridges the initial list load, and stale pending picks clear when their workspace leaves a ready list.
- **One 16px vertical rhythm.** The chat column gap and in-group tool-row gap are both 16px, replacing the 10px in-group gap plus a negative cross-group margin.
- **Header title reads 14/20 with no turns counter**; StateDot ongoing and the turn tail use a stepped pixel-chase loading language; `body` gets grayscale antialiasing (`-webkit-font-smoothing` and the Firefox macOS equivalent).
-
-## Alternatives considered
-
- **Position menus synchronously from anchor rects before mount.** Rejected: the list's own size is unknown until it lays out, so clamping to the viewport still needs a post-layout measure; measuring a hidden mounted node is the pattern React and Floating UI document.
- **Filter empty assistant messages host-side.** Rejected: the node is real model output that Trajectory and replay must keep; only the chat presentation should skip it, and the web layer is pure presentation by contract.
- **Relativize paths in each tool's presenter.** Rejected: the redundancy is shared by every path-summarizing tool; one display-only pass in `toolRowModel` covers them all and non-chat consumers keep absolute paths.
- **Keep the mask-based sweep.** Rejected: the mask dims the entire row content including state dots, and its exit transition fought the hover icon crossfade; an overlay band composites above the content without touching its alpha.
- **Keep showing the deleted workspace's name in the chip.** Rejected: the chip is the selector for the *next* session; echoing a cwd whose workspace the user just deleted misrepresents the current pick.
-
-## Consequences
-
-Chat renders fewer flow items than the snapshot has nodes: anyone counting rendered blocks against nodes must account for skipped render-nothing assistants (the chat-view spec pins this). The path relativization is a prefix check against the session cwd, so a workspace rename mid-session shows absolute paths until the summary re-derives — accepted as display-only staleness. The uniform 16px rhythm retires the tighter 10px tool-run look; a future denser layout would reintroduce a second constant deliberately. The menu pre-render adds one hidden layout pass per open, negligible at menu sizes.
-
-## Testing
-
-`chat-view.spec.tsx` pins the render-nothing grouping (including the interrupted exception); `chat-tool-row.spec.tsx` pins cwd relativization inside/outside the workspace and with an empty cwd; `atoms.spec.tsx` and `workspace-picker.spec.tsx` cover the menu and chip states; the full ui-conversation, ui-primitives, and ui-workspace suites pass.

-[English](2026-07-28-web-conversation-polish-sweep.md) | 中文
-
-## 问题
-
-一次针对 web GUI 对话界面的设计评审发现了一批视觉呈现缺陷：portal 菜单在重新定位前会先在错误位置绘制一帧（打开时可见跳动）；只要某条步骤消息只携带工具调用头，聊天列就会把一次工具运行拆成好几组；工具行摘要打印以工作区为根的绝对路径，占掉行内大部分空间；运行中行的扫光效果用 alpha 遮罩实现，把整行都压暗；hero 区的工作区 chip 会从会话 cwd 里复现已删除工作区的文件夹名；标题栏还在 13px 的标题旁显示一个没人需要的轮次计数。
-
-## 决策
-
-本次修复仅改动展示层；不会有任何内容进入会话日志。
-
- **Portal 菜单先隐藏预渲染，绘制前完成测量。**菜单列表以 `visibility: hidden` 挂载在 (0,0)，在 `useLayoutEffect` 中测量，显示时已处于最终位置。菜单与视口保持 12px 间距并支持内部滚动；工作区创建操作固定在不滚动的页脚区。
- **聊天流跳过不渲染任何内容的助手节点。**已定稿的助手节点若其块仅含工具调用头和空白的文本／推理（reasoning）内容，就会从流推导中剔除，于是连续的工具结果合并为一组。被中断的节点始终渲染（它们携带「已停止」标记）。
- **工具行摘要把以工作区为根的路径转为相对路径。**会话 cwd 经由 toolview 插槽契约（`ToolRowOwnerProps.cwd`）逐层传递，`toolRowModel` 从以其开头的摘要中剥去该前缀；工作区之外的路径保持原样。这只影响显示：工具参数与日志均不受影响。
- **运行中的扫光效果改为高光带叠加层。**一条固定宽度的 `::after` 渐变光带横向扫过整行（即 deepsuite 的 ShimmerText 模式），取代先前的 `mask-image` 方案，ToolRow 与 Bash toolview 两处均已替换。
- **hero 区的工作区 chip 是选择器，而非回显。**没有有效选中项时（冷启动，或列表稳定后工作区被删除），它显示「Choose workspace」占位文案；由 cwd 推导的名称只用于衔接列表的首次加载，尚待确认的选择所对应的工作区从已就绪的列表中消失时，该陈旧选择会被清除。
- **统一为 16px 的纵向节奏。**聊天列间距与分组内工具行间距统一为 16px，取代原先「分组内 10px 间距加跨分组负外边距」的做法。
- **标题文字改为 14/20，标题栏去掉轮次计数**；StateDot 的进行中状态与轮次尾部采用逐格推进的像素追逐式加载视觉语言；`body` 启用灰度抗锯齿（`-webkit-font-smoothing` 及 Firefox 在 macOS 上的等价设置）。
-
-## 考虑过的替代方案
-
- **挂载前根据锚点矩形同步定位菜单。**不予采纳：列表自身尺寸在布局完成前无从得知，向视口内收拢仍然需要布局后测量；对已挂载的隐藏节点做测量正是 React 与 Floating UI 文档记载的模式。
- **在宿主侧过滤空的助手消息。**不予采纳：该节点是真实的模型输出，Trajectory 与回放都必须保留它；只有聊天展示应当跳过它，且按契约 web 层只负责呈现。
- **在每个工具各自的 presenter 中做路径相对化。**不予采纳：这种冗余是所有输出路径摘要的工具共有的；在 `toolRowModel` 里做一次仅影响显示的处理即可覆盖全部工具，非聊天消费方仍拿到绝对路径。
- **保留基于遮罩的扫光。**不予采纳：遮罩会把包括状态圆点在内的整行内容压暗，其退出过渡还与悬停图标的交叉淡入淡出相互冲突；叠加光带在内容之上合成，完全不触碰内容的 alpha。
- **让 chip 继续显示已删除工作区的名称。**不予采纳：chip 是为*下一个*会话服务的选择器；用户刚删掉某个工作区，还回显它的 cwd，就是在错误呈现当前的选择。
-
-## 后果
-
-聊天渲染出的流条目数少于快照中的节点数：凡是拿渲染出的块与节点数对账的人，都必须把被跳过的「不渲染任何内容」的助手节点计算在内（chat-view 规格测试固定了这一点）。路径相对化只是针对会话 cwd 的前缀检查，因此会话中途重命名工作区后，摘要在重新推导前会显示绝对路径，这被接受为仅影响显示的陈旧状态。统一的 16px 节奏淘汰了原先更紧凑的 10px 工具运行外观；将来若要更紧凑的布局，应当有意识地重新引入第二个常量。菜单预渲染让每次打开多一次隐藏布局计算，在菜单的尺寸量级下开销可忽略。
-
-## 测试
-
-`chat-view.spec.tsx` 锁定了「不渲染任何内容」节点的分组行为（含被中断节点这一例外）；`chat-tool-row.spec.tsx` 锁定了工作区内、工作区外以及 cwd 为空时的 cwd 相对化行为；`atoms.spec.tsx` 与 `workspace-picker.spec.tsx` 覆盖菜单与 chip 的各种状态；ui-conversation、ui-primitives 与 ui-workspace 的全量测试套件通过。

-# Agent Note: TUI model-context resolution defers on the adapter-registration race

-## Problem
-
-Cordis activates plugins by service availability, not configuration order, so the TUI (whose `inject` requires only the `llm` service) can mount before a configured adapter plugin such as `dsh-llm-pi-ai` finishes registering its provider routes. The TUI's model controller resolves the selected model's context window immediately on mount; when the agent's route pointed at a not-yet-registered provider, `resolveModelInfo` rejected with `NO_ADAPTER` and every fresh session printed `Could not resolve model context: no adapter registered for provider "…"` — a spurious error for a fully working configuration (the adapter registered milliseconds later, and chatting worked).
-
-## Decision
-
-The TUI model controller treats a `NO_ADAPTER` rejection of its context-window resolution as a transient state rather than an error: it parks the resolution silently and re-resolves on the next `llm/adapters-updated` commit — the payload-free registry notification `LlmService` already fires at every route commit point. A commit that still lacks the route parks the wait again, so unrelated topology changes stay silent. Any target change re-enters the resolution and clears the pending wait, so the deferred state can never go stale against the current selection; every other resolution error still prints the notice.
-
-## Alternatives considered
-
-**Have the TUI wait for boot to settle before resolving.** The TUI has no Loader dependency (tests and embedders run without one) and "settled" is not observable from inside a plugin; adding a Loader coupling for one cosmetic resolution inverts the dependency direction.
-
-**Poll or retry with a timer.** A timer guesses at activation latency, still mis-prints on a slow adapter, and adds a tunable with no owner. The registry already announces every commit through `llm/adapters-updated`; subscribing is precise and free.
-
-**Order the config so adapters load first.** Row order carries no load semantics in the Loader (activation is service-driven by design), so this cannot be expressed in configuration.
-
-**Suppress NO_ADAPTER errors entirely.** A permanently missing adapter (typo in the provider name) would then never surface in the context-window path. Deferring keeps the signal: a wrong provider name still shows `model unset`-like behavior in the selector and fails loudly at dispatch, while the startup race resolves itself.
-
-**Resolve the context window per submitted message instead of at mount.** The send path already resolves per step (`prepareCall()`), and the indicator is displayed continuously, not only when sending; per-submit display resolution would leave the indicator blank until the first message and re-run adapter I/O for a value that only changes on route changes.
-
-## Consequences
-
-A genuinely misconfigured provider no longer prints the context-resolution error at startup — it surfaces at first dispatch instead, which is where the failure is actionable. The controller subscribes to every `llm/adapters-updated` commit but acts only while a wait is parked; the listener's disposer is released by the channel's `detachListeners()` through the controller's `detach()`, symmetric with the sibling channel listeners. Covered by three TUI tests: the deferred resolution stays silent through an unrelated commit and completes when the route's commit arrives, a target change drops the stale wait, and after channel detach a registry commit no longer re-enters resolution.

-Cordis 按服务可用性而非配置顺序激活插件，因此 TUI（其 `inject` 只要求 `llm` 服务）可能在 `dsh-llm-pi-ai` 这类已配置的适配器插件完成提供方路由注册之前就挂载。TUI 的模型控制器在挂载时立即解析所选模型的上下文窗口；当 agent 的路由指向尚未注册的提供方时，`resolveModelInfo` 以 `NO_ADAPTER` 拒绝，于是每个新会话都会打印 `Could not resolve model context: no adapter registered for provider "…"` —— 对一份完全正常的配置报出的虚假错误（适配器几毫秒后就完成注册，对话也一切正常）。

-TUI 模型控制器把上下文窗口解析中的 `NO_ADAPTER` 拒绝视为瞬态状态而非错误：静默搁置这次解析，并在下一次 `llm/adapters-updated` 提交时重新解析——这是 `LlmService` 本就在每个路由提交点发出的无载荷注册表通知。若某次提交仍缺少该路由，等待会被再次搁置，因此无关的拓扑变化保持沉默。任何目标变更都会重新进入解析并清除挂起的等待，因此延后状态绝不会相对当前选择变陈旧；其他所有解析错误仍照常打印通知。
-
-## Alternatives considered
-
-**让 TUI 等启动结算后再解析。** TUI 不依赖 Loader（测试和嵌入方在没有 Loader 的环境下运行），而且"已结算"在插件内部不可观测；为一次外观性的解析引入 Loader 耦合会颠倒依赖方向。
-
-**用定时器轮询或重试。** 定时器只能猜测激活延迟，遇到慢适配器仍会误报，还会引入一个没有归属者的可调参数。注册表本就通过 `llm/adapters-updated` 公告每次提交；订阅它既精确又零成本。
-
-**调整配置顺序让适配器先加载。** Loader 中行顺序不承载加载语义（激活按设计由服务驱动），因此这无法用配置表达。
-
-**彻底压制 NO_ADAPTER 错误。** 那样的话，永久缺失的适配器（提供方名字拼错）在上下文窗口路径上就永远不会暴露。延后重试保留了信号：错误的提供方名字仍会在选择器中表现出类似 `model unset` 的行为，并在分派时大声失败，而启动竞争则自行化解。
-
-**改为在每次提交消息时解析上下文窗口，而不是在挂载时。** 发送路径本就按步解析（`prepareCall()`），且指示器是持续显示的，不只在发送时；按提交解析显示值会让指示器在首条消息之前一直空白，并为一个仅在路由变化时才变的值反复执行适配器 I/O。
-
-## Consequences
-
-真正配置错误的提供方不再在启动时打印上下文解析错误——它改在首次分派时暴露，那才是该失败可以被处理的地方。控制器订阅每次 `llm/adapters-updated` 提交，但只在有等待被搁置时才动作；监听器的 disposer 经由控制器的 `detach()` 在频道的 `detachListeners()` 中释放，与同级频道监听器保持对称。由三个 TUI 测试覆盖：延后的解析在无关提交中保持沉默、在该路由的提交到来时完成；目标变更丢弃陈旧等待；频道 detach 之后注册表提交不再重新进入解析。

-## Problem
-
-The transient layout store initialized details to its 360px contract width. The first connected Session and every full reload therefore reserved a right column before the user selected any detail content. Chat tool rows deliberately remain inline and do not open details, while Trajectory rows open the panel when an event is selected, so an open layout default did not represent an active detail selection.
-
-## Decision
-
-The layout store initializes details to zero while retaining the existing 360px contract default for `openDetails()`. `AppFrame` keeps the details slot mounted at zero width, so an explicit entry point such as Trajectory event selection can open the panel without remounting its subtree. The [Session ownership lifecycle](2026-07-29-web-details-session-lifecycle.md) remains authoritative: unselected surfaces derive zero width without taking ownership, returning to the same Session preserves an explicitly opened width, and selecting a different Session closes it.
-
-Panel geometry remains transient. No browser storage key is introduced, and reload restores the sidebar default while details returns to zero. Component tests pin the store default, mounted zero-width slot, drag and concession behavior after explicit opening, and Session ownership transitions. The keyless shipped-composition regression pins the closed first Session, reload, new-session surface, and subsequent Session selections.
-
-## Alternatives considered
-
-**Persist the last open or closed preference.** Rejected because reload should have a deterministic closed baseline, and persisting geometry would reintroduce stale viewing state across browser sessions.
-
-**Keep details open until Chat receives a replacement selection gesture.** Rejected because empty space is not useful detail content. Chat's inline tool-row interaction and any future detail-selection gesture are separate product decisions.
-
-**Remove the details column and layout service.** Rejected because Trajectory already opens event details through this seam, and keeping the mounted slot preserves that working interaction.
-
-## Consequences
-
-New, restored, and reloaded Sessions use the full center area until an explicit details action opens the right column. Trajectory event selection can still open details at 360px and its close control returns the track to zero; Chat tool rows remain geometry-inert. Switching to another Session closes an opened panel, and no panel state survives reload.

-## 问题
-
-瞬时布局 store 原本将详情栏初始化为 360px 的契约宽度。因此，首个已连接会话以及每次完整重新加载都会在用户选择任何详情内容之前预留右侧栏。Chat 工具行有意保持内联，不会打开详情栏；Trajectory 行则会在选中事件时打开详情栏。因此，布局默认打开并不表示存在有效的详情选中项。
-
-## 决策
-
-布局 store 将详情栏初始化为零，同时保留 `openDetails()` 现有的 360px 契约默认宽度。`AppFrame` 仍以零宽度挂载详情 slot，因此 Trajectory 事件选择等显式入口可以打开详情栏，而无需重新挂载其子树。[会话所有权生命周期](2026-07-29-web-details-session-lifecycle.md)仍是权威契约：未选中表面会派生零宽度而不取得所有权；返回同一会话时会保留显式打开后的宽度；选择不同会话时则会关闭详情栏。
-
-面板几何信息仍是瞬时状态。系统不新增浏览器存储键；重新加载会恢复侧边栏默认值，并使详情栏回到零宽度。组件测试固定验证 store 默认值、保持挂载的零宽度 slot、显式打开后的拖动与让步行为，以及会话所有权过渡。无密钥的已交付组合回归测试固定验证首个会话保持关闭、重新加载、New Session 表面和后续会话选择。
-
-## 考虑过的替代方案
-
-**持久化最后一次打开或关闭的首选状态。** 之所以否决：重新加载必须具有确定的关闭基线，而持久化几何信息会在浏览器会话之间重新引入陈旧的查看状态。
-
-**在 Chat 获得替代性的选择手势前保持详情栏打开。** 之所以否决：空白区域不是有用的详情内容。Chat 的内联工具行交互与未来可能增加的详情选择手势属于彼此独立的产品决策。
-
-**移除详情栏和布局服务。** 之所以否决：Trajectory 已经通过该服务边界打开事件详情；继续挂载该 slot 可以保留这一正常工作的交互。
-
-## 后果
-
-新建、恢复和重新加载的会话会使用完整的中央区域，直至显式详情操作打开右侧栏。Trajectory 事件选择仍可将详情栏打开至 360px，其关闭控件会使轨道回到零；Chat 工具行仍不改变几何信息。切换到其他会话会关闭已打开的详情栏，并且任何面板状态都不会在重新加载后保留。

-# Agent Note: The composer's two text layers share one scrollport
-
-Status: implemented
-Archived: 2026-08-20
-
-English | [中文](2026-07-31-composer-text-layers-share-one-scrollport.zh.md)
-
-## Problem
-
-The composer paints its text in two stacked layers ([InputBar](../../../../packages/client/ui-conversation/src/client/skeleton/InputBar.tsx)): the `<textarea>` owns the value, the selection, and the caret but renders its own glyphs `color: transparent`, and every visible character is painted by the `[data-input-backdrop]` div beneath it, which also carries the claim-token highlight, the chips, and the ghost hint. That split is what makes chips and highlights possible at all — a textarea cannot style a range of its own text. The draft box is capped at 14 lines, so past the cap something has to scroll.
-
-Two layers with two scroll offsets fail in two stages, and this change is the second one.
-
-The first was static. The backdrop is `position: absolute; inset: 0; overflow: hidden` — clipped, not scrolled — and nothing in the browser links its offset to the textarea's, so past the cap the caret moved and the words stayed frozen at line 1. Below the cap that is invisible, because both layers rest at 0; the defect was exactly as old as the cap and hid behind the resting state that every screenshot captured. It was fixed by mirroring the textarea's `scrollTop` onto the backdrop from a `scroll` listener, and that made the two layers agree **at rest**.
-
-The second is what a user then reported: swiping quickly from the top of a long draft throws the caret up out of its own text, as though it carried momentum, and it settles back a moment later. The mirror is the cause. A wheel gesture scrolls the textarea on the compositor, off the main thread; the `scroll` event that drives the assignment is dispatched afterwards, so for the frames in between the caret sits at the new offset and every glyph sits at the old one. Measured on a standalone harness of the same geometry, moving the offset 200px and reading the caret's distance to its own glyphs before the task ends: chromium 203px, firefox 202px, WebKit 203px of separation, settling to the fixed line-box constant (3/2/3) a frame or two later. Every engine, every gesture, proportional to how fast the user scrolls.
-
-No listener can close that gap, because the gap is the definition of a listener: it runs after the thing it reacts to. Anything that keeps two boxes equal in JavaScript is a frame behind a compositor that moves one of them without asking.
-
-## Decision
-
-One scrolling box, holding both layers.
-
-`[data-input-scroll]` is the composer's only scrollport and carries the 14-line cap. Inside it, the auto-grow stack is as tall as the **whole** draft — the hidden mirror div is in normal flow and no longer capped, so it sizes the stack to the full text — and the backdrop and textarea ride that height absolutely. The textarea is `overflow: hidden` with no scrollable overflow of its own; it can no longer hold an offset at all.
-
-The browser then applies one offset to both layers, in the same frame, on the same compositor. The caret is bound to its glyphs by construction rather than by upkeep: there is no code to run, no event to wait for, and no state that can be one frame stale. The wheel-chaining handler stays, retargeted from the textarea to the scrollport, and remains the only listener on the box.
-
-Safari's native text control has one engine exception: deleting across a soft-wrap threshold can retain the former line layout after the mirror shrinks. The [Safari soft-wrap recovery](2026-08-13-safari-textarea-soft-wrap-reflow.md) restores the zero-overflow invariant before paint without changing the one-scrollport design.
-
-Two things the previous mechanism needed are gone with it:
-
-**The backdrop's trailing-line sentinel.** It existed to keep the two boxes' scroll extents equal — a textarea reserves a line box for the caret after a final newline while `white-space: pre-wrap` collapses a text node's trailing newline, so a draft ending in a newline made the backdrop one line shorter and clamped the mirrored offset a line above the caret. With one scrollport the backdrop's own extent decides nothing: the mirror div sizes the stack for both layers, both start at the same top, and a layer whose content ends earlier simply paints nothing on the last line. The shape is worth keeping in mind rather than the mechanism: it is the one that measured 628 against 652 when the two boxes had to agree on a height.
-
-**The wrap-width premise.** All three layers now resolve their width inside the scrollport, so a scrollbar that consumes layout space costs them the same width by construction. This closes the divergence the superseded note recorded as open and unfixable by any property: WebKit reserved gutter space for the `overflow-y: auto` textarea and not for the `overflow: hidden` layers beside it, laying the textarea out 768 against 776 — worth 2 to 5 wrapped lines on a long draft, i.e. glyphs under the wrong caret on the one engine where it was observable. Measured on the harness after the change, all three layers report one width on all three engines Playwright ships.
-
-**Edits the composer performs itself now ask for the reveal.** Paste and cut suppress the native edit — the machine owns the draft and the undo log — and restore the caret with `setSelectionRange`, which reveals nothing: measured in chromium and WebKit, pasting a long block leaves the view where it was while the caret sits at the end of what was pasted. That defect predates this change (Firefox happened to reveal it, in the old geometry only) and is fixed here because one scrollport is what finally makes the reveal ours to perform. The two restores share one helper that measures the caret against the hidden mirror — same draft, same metrics, same wrap width, so a Range collapsed at the caret's index reports where the caret is without a caret API — and scrolls the minimum that brings it inside, which is what the browser does for typing.
-
-One shape needs a rule of its own, because the engines disagree about it: a caret straight after a newline sits on a line with nothing on it to measure, which is where a trailing-newline draft ends. chromium returns **no client rects at all** for the collapsed position — an all-zero box, which would send the reveal the wrong way — firefox reports the line above, and WebKit the right one. The helper therefore measures the newline the caret just left, whose box is the line it came from, and steps one line down; all three then land on the same offset (649 of 652, with the caret's line at 315 inside the 336px box). A non-collapsed Range over that newline returns a real rectangle on all three engines even when the draft ends in consecutive newlines, so each trailing blank line composes with the same rule.
-
-Revealing the caret is the one thing that now depends on the browser rather than on us: with no offset of its own, the textarea's scroll-into-view has to walk up to the scrollport. It does, on every engine measured — typing at the draft's end brings the scrollport to the caret (625, 626 and 628 of a 628px maximum in chromium, firefox and WebKit), walking the caret back up with `ArrowUp` scrolls back to it, and typing after scrolling away returns to it.
-
-## Alternatives considered
-
-**Mirror `scrollTop` onto the backdrop from a `scroll` listener.** The superseded decision, and correct at rest: it is what made a long draft scrollable at all. Rejected now because it cannot be correct in motion — it is a main-thread reaction to a compositor-thread fact — and because it needed two premises to stay true that the single scrollport does not need at all (equal extents, equal wrap widths), each of which had already failed once.
-
-**Translate the backdrop with `transform: translateY(-scrollTop)` instead of assigning an offset.** Same lag: still main-thread, still driven by the same event. It additionally papers over extent divergence rather than making the layers agree, so a mismatch resurfaces the moment anything measures the backdrop.
-
-**Drive the backdrop from a scroll-driven animation (`animation-timeline: scroll()`).** This would run the coupling on the compositor and genuinely eliminate the lag while keeping two boxes. Rejected on support: Safari does not implement it and Firefox has only recently, so the composer would keep the reported defect on the engines that lack it, and the fallback path would be the mechanism being replaced.
-
-**Scroll both layers from JavaScript, with the textarea `overflow: hidden` and a wheel handler assigning both offsets in one task.** No divergence during wheel gestures, since nothing scrolls without us. Rejected because it replaces native scrolling — momentum, trackpad rubber-banding, scrollbar dragging, keyboard scrolling — with a hand-written approximation, and the caret-reveal path (the browser setting the textarea's own offset) still lands asynchronously.
-
-**Keep the cap on the mirror and just wrap today's structure in a scroller.** The layers would stay window-sized, not draft-sized: `inset: 0` on an absolutely positioned child resolves against the scrollport's padding box, not its scrollable overflow area, so both layers would scroll away from the content that is supposed to be underneath them. The stack has to be the full draft height for the arrangement to mean anything.
-
-**Give the backdrop `overflow: auto` and let it scroll itself.** It would then have an offset of its own to keep in step, which is the same problem plus a second scrollbar painted over the input. The backdrop is a projection of the textarea, not an independently navigable surface.
-
-**Drop the backdrop and style the textarea's own text.** This removes the layer split and the whole class of desync with it. Rejected because it is not implementable: a textarea renders one uniform text run, so the claim-token highlight, the chips, and the ghost hint — the reasons the backdrop exists — have no way to be expressed. Losing them to fix scrolling trades a bounded defect for a feature deletion.
-
-**Render the draft in a `contenteditable` div.** One element, one offset, styleable ranges. Rejected as far out of proportion: `contenteditable` would put IME composition, undo/redo, selection semantics, and paste normalization back on us, all of which the textarea plus the input machine currently handle, and the machine already owns an undo log that assumes a textarea's value semantics.
-
-**`scrollbar-gutter: stable` on all three layers.** Tried and reverted while the textarea was the scroller: WebKit applied it to `overflow-y: auto` and not to `overflow: hidden`, leaving the same 8px gap unclosed while costing every chromium user 8px of text column. Moot now — the layers share a containing block, so there is nothing to reserve.
-
-**`scrollbar-width: none` on the scrolling layer.** Would equalize widths by hiding the thumb. Rejected: the composer deliberately shows one once the draft passes the cap — `.card` binds the l2 scrollbar tokens for exactly that — and it is the only affordance saying a long draft continues below.
-
-## Consequences
-
- The caret cannot leave its glyphs. The browser scrolls one box, so the separation between where the textarea puts a line and where the backdrop paints it is a fixed line-box constant at every offset, mid-gesture included. The scenario measures exactly that number.
- The scrollbar moved from the textarea to the scrollport — the same visual place, one box out. The `.card` l2 token binding still inherits down to it.
- Chips, claim-token highlights, and text-ref marks stay aligned with their glyphs while scrolled, because they are positioned inside the backdrop and move with it. The decoration walk is unchanged apart from the dropped sentinel.
- On Firefox and WebKit, clicking into a composer whose draft overflows the cap now also scrolls the conversation transcript to its bottom: the caret's scroll-into-view walks past the composer's scrollport up to the transcript scrollport, which a textarea shorter than its box never made it do. Chromium does not. Measured, with `overscroll-behavior: contain` and `contain: paint` both tried and neither stopping the walk — there is no CSS that ends scroll-into-view chaining. Accepted: it scrolls toward the bottom, where the composer already sits, and the alternative is a caret visibly detached from its text on every engine.
- Paging and drag-selection are unchanged, both measured old against new. `PageDown`/`PageUp` never moved a textarea's caret in the first place — chromium scrolls a page and leaves `selectionStart` where it was, in both geometries; only the box that scrolls differs. Drag-selecting past the bottom edge still auto-scrolls, and to the same place (chromium 628/628, firefox 625/620, WebKit 170/170 — WebKit's slower autoscroll is equally slow before and after).
- The composer's own `focus()` calls pass `preventScroll` — the unlock/session-switch effect and the focus-keeping mousedown on the toolbar buttons — so a focus nobody gestured for cannot move the transcript through the taller textarea's reveal chain. Suppressing that walk hands the caret back to us on the one path where it matters: the composer DOM is reused across sessions, so switching to a longer draft keeps the previous offset while the value swap puts the caret at the new draft's end. Measured on all three engines, that leaves the caret 940px below a box sitting at 0; the effect therefore reveals it in its own scrollport, landing at 625 of 628 — what the old geometry reached at 628 through the browser. The mousedown path needs no reveal: the caret has not moved, and the next keystroke gets the browser's native one. A separate reveal-only effect handles a non-empty draft that arrives after render: `ConversationSession` seeds a persisted draft in its own mount effect, which runs AFTER this component's, so the first reveal would otherwise measure an empty mirror and never run again for the draft that then appeared. The second effect never focuses, so ordinary empty/non-empty transitions such as send-clear or failed-send restore cannot take focus from another control.
- Undo and redo can change the draft without a caret restore or reveal: the machine replays a previous draft and the DOM selection stays where the browser clamps it. That predates this change and is unchanged by it — named here because the two restores that DO reveal make the omission look deliberate, and the helper is sitting right there if it is ever reported.
- Any layer added beside the backdrop belongs INSIDE the scrollport and must be as tall as the draft, or it reintroduces exactly this defect. This is the composer's standing hazard: the two-layer split is load-bearing for chips and highlights, so the coupling has to be structural, not maintained.
-
-## Testing
-
-The unit spec in [input-bar.spec.tsx](../../../../packages/client/ui-conversation/tests/input-bar.client.spec.tsx) asserts what jsdom can see: that one scrolling box contains both the textarea and the backdrop, that the backdrop's text is now the draft and nothing else, and that a late persisted draft reveals its caret without taking focus from another control. jsdom reports `scrollHeight === clientHeight` for every element and never scrolls one, so the geometry belongs to the browser scenario; the wheel-chaining cases stub the scrollport's metrics rather than the textarea's.
-
-[composer-draft-scroll.e2e.ts](../../../../apps/web/tests/composer-draft-scroll.e2e.ts) measures the rest in chromium against the built client: a 40-line draft in a fresh workspace's blank composer, zero model calls. Every metric is read in the caret's own coordinate frame — where the textarea places line n, offset included — against a DOM Range over the backdrop's text for the same line, because that difference is what a user sees. The decisive case changes the offset and re-reads that difference **before the task ends**, which is before any `scroll` listener could have run: 0 with one scrollport, and the full delta with a mirror. A vacuity guard asserts the draft overflows the capped box first, and separate cases cover the cap, one wrap width across all three layers, a wheel gesture, a trailing-newline draft, and the caret-reveal path that the textarea's own scrolling used to handle — typing after scrolling away must bring the scrollport back to the caret.
-
-A separate case covers the paste path end to end: a short draft, the caret at its end, and one `paste` event carrying real clipboard data — the same event a Cmd-V delivers, through the same handler — then the offset and the last pasted line. It waits on the offset rather than on the draft overflowing, because the restore lands one frame after the machine commits the draft; a build without the reveal fails that wait.
-
-The two-geometry comparison behind the decision was measured on a standalone harness before implementing, since the old and new arrangements cannot both exist in the app at once: the same-task separation is 203/202/203px old against 3/2/3px new (chromium/firefox/WebKit), the wrap widths 768-against-776 old on WebKit against 1264/1264/1264 new on all three, and the textarea's own scrollable overflow 0 in the new geometry, which is what makes a second offset impossible rather than merely equal.
-
-Note that the composer ships inside a client-module bundle, so `pnpm run build:web` alone does not pick up a change to `InputBar.tsx` — the package build must run for the browser lane to see it, and a scenario run against a stale `lib/` asserts against an older client than the tree.
