Subject: [PATCH 001/102] feat(util): extract dsh-atomic-write and migrate
 settings-local writes

writeFileAtomic: exclusive-create random-suffix temp + rename carrying the
caller-stated mode; settings-local persistSection now consumes it. The
credentials-local store shares it next.

+# dsh-atomic-write
+
+English | [中文](README.zh.md)
+
+Zero-dependency atomic file replacement shared by file-backed stores that must never leave partial, symlink-hijacked, or wider-than-intended content on disk — the user-settings document (`dsh-settings-local`) and the credentials store (`dsh-credentials-local`).
+
+## Surface
+
+```ts
+import { writeFileAtomic } from '@deepseek-ai/dsh-atomic-write'
+
+await writeFileAtomic('/home/u/.dsh/settings.yaml', text, { mode: 0o600 })
+```
+
+One export. The contract, in the order failures would exploit it:
+
+- **Exclusive-create temp** (`wx`, random suffix): the open refuses to follow a symlink planted at a guessable temp path.
+- **The fresh inode carries `mode` through the rename**: replacing a wider-permission file narrows it without a chmod race. `mode` is required so the permission decision stays visible at every call site (subject to the process umask, like every fresh inode).
+- **`rename` replaces a symlinked target itself**, never writing through to its referent.
+- **Same-directory sibling** keeps the rename on one filesystem, so the swap stays atomic.
+- Parent directories are created; on any failure the temp is removed and the failure rethrown; readers observe either the old or the new complete content.
+
+## Model Experience
+
+None, as this is a pure filesystem primitive; nothing here reaches a model request.
+
+## Known Limitations and Deferred Work
+
+- **Atomic, not durable** — no `fsync` of the file or its directory, so after a crash the rename may be observed unwound. The file-backed stores here re-read and republish on boot, keeping durability the caller's policy.
+- **String content only** — no `Buffer` or stream form until a consumer needs one.

+# dsh-atomic-write
+
+[English](README.md) | 中文
+
+零依赖的原子文件替换，供绝不允许在磁盘上留下半截内容、被符号链接劫持或权限过宽内容的文件型存储共用——用户设置文档（`dsh-settings-local`）与凭据存储（`dsh-credentials-local`）。
+
+## 接口面
+
+```ts
+import { writeFileAtomic } from '@deepseek-ai/dsh-atomic-write'
+
+await writeFileAtomic('/home/u/.dsh/settings.yaml', text, { mode: 0o600 })
+```
+
+仅一个导出。契约按攻击面利用顺序列出：
+
+- **独占创建临时文件**（`wx` + 随机后缀）：open 拒绝跟随预先埋在可猜测临时路径上的符号链接。
+- **全新 inode 携带 `mode` 走完 rename**：替换权限过宽的旧文件时直接收窄，不存在 chmod 竞态。`mode` 为必填，让权限决策始终可见于每个调用点（与所有新建 inode 一样受进程 umask 影响）。
+- **`rename` 替换的是符号链接目标本身**，绝不写穿到其指向的文件。
+- **同目录兄弟文件**保证 rename 落在同一文件系统上，交换保持原子。
+- 自动创建父目录；任何失败都会清理临时文件并重新抛出；读者只会看到旧内容或完整的新内容。
+
+## Model Experience
+
+None, as this is a pure filesystem primitive; nothing here reaches a model request.
+
+## Known Limitations and Deferred Work
+
+- **原子但不保证落盘持久**——不对文件或目录做 `fsync`，崩溃后可能观察到 rename 被回退。此处的文件型存储在启动时重新读取并重新发布，持久化策略留给调用方。
+- **仅支持字符串内容**——在出现真实消费者之前不提供 `Buffer` 或流式形态。

References-not-values doctrine: settings carry env-shaped CredentialRefs,
providers own storage. Per-operation resolve, UI-safe describe, fail-loud

+English | [中文](README.zh.md)
+
+Abstract credential seam (`ctx.credentials`). One doctrine, three consequences:
+
+**Configuration carries references to secrets, never the secrets.** A settings section or `cordis.yml` entry says `apiKeyEnv: DEEPSEEK_API_KEY`; the value behind that reference lives with a credential provider. So the settings document stays safe to sync and to render in a configuration UI, `describe()` can answer "is this configured, where from, can I write it" without ever holding a value, and rotating a secret touches no configuration file.
+
+**Consumers resolve per operation.** `resolve(ref)` is called at the start of each operation (the LLM adapters resolve once per model request) and never cached across operations — that read is what makes a changed credential reach the very next request without restarting any plugin.
+
+**An empty stored value is absent.** Everywhere: `resolve` skips it, `describe` reports it unconfigured. A blank can never masquerade as a configured secret.
+
+## Surface
+
+```ts
+import { credentialRef } from '@deepseek-ai/dsh-credentials'
+
+const ref = credentialRef('DEEPSEEK_API_KEY')            // POSIX shell identifier, branded
+const hit = await ctx.credentials.resolve(ref)           // { value, source } | undefined
+const info = await ctx.credentials.describe(ref)         // { configured, source?, writable } — never the value
+await ctx.credentials.set(ref, 'sk-…')                   // rejects while a read-only source shadows the ref
+await ctx.credentials.unset(ref)                         // no-op when absent; same shadowing rule
+```
+
+`credentials/updated (ref)` fires after a committed change to a provider-managed source — a `set`, an `unset`, or an external edit observed in storage. Ambient process-environment changes are not observable and never emit. Consumers do not need the event (they re-resolve per operation); it exists for configuration UIs refreshing a "configured" badge.
+
+The shadowing rule on `set`/`unset` is deliberate fail-loud: when a read-only source (the live process environment, in the local provider) currently supplies the reference, a write would appear to succeed while resolution keeps returning the shadowing value — the seam rejects instead, and `describe().writable` lets a UI render the reference read-only up front.
+
+## Providers
+
+[`dsh-credentials-local`](../credentials-local/README.md) layers the live process environment over a `$DSH_HOME/.env` file. The seam shape leaves room for keyring-, helper-command-, and KMS-backed providers; a remote settings provider never needs to carry secrets.
+
+## Model Experience
+
+Indirectly: a resolved value authorizes provider requests; the consuming adapter owns every model-visible surface.
+
+#### KV Cache effect
+
+No direct invalidation; credentials never enter a request prefix.
+
+## Known Limitations and Deferred Work
+
+- **No enumeration** — the seam answers questions about references it is given; configuration surfaces learn the references from settings schemas, so a `list()` has no current consumer.
+- **References are environment-variable-shaped** — one flat POSIX-identifier namespace until a provider needs richer addressing.
+- **Process-environment changes are invisible** — no event can fire for them; a UI only re-reads `describe()` on its own navigation.

+# dsh-credentials
+
+[English](README.md) | 中文
+
+抽象凭据 seam（`ctx.credentials`）。一条准则，三个推论：
+
+**配置只携带对秘密的引用，绝不携带秘密本身。** settings 分节或 `cordis.yml` 条目写 `apiKeyEnv: DEEPSEEK_API_KEY`，引用背后的值归凭据 provider 所有。于是设置文档可以放心同步、放心渲染进配置界面；`describe()` 无需持有值就能回答"配置了吗、来自哪层、能否写入"；轮换秘密不触碰任何配置文件。
+
+**消费方按操作解析。** `resolve(ref)` 在每个操作开始时调用（LLM adapter 每次模型请求解析一次），绝不跨操作缓存——正是这次读取让改过的凭据无需重启任何插件就作用于下一次请求。
+
+**空的存储值等于不存在。** 处处如此：`resolve` 跳过它，`describe` 报告未配置。空白永远不会伪装成已配置的秘密。
+
+## 接口面
+
+```ts
+import { credentialRef } from '@deepseek-ai/dsh-credentials'
+
+const ref = credentialRef('DEEPSEEK_API_KEY')            // POSIX shell 标识符，品牌类型
+const hit = await ctx.credentials.resolve(ref)           // { value, source } | undefined
+const info = await ctx.credentials.describe(ref)         // { configured, source?, writable } —— 绝不含值
+await ctx.credentials.set(ref, 'sk-…')                   // 被只读来源遮蔽时拒绝
+await ctx.credentials.unset(ref)                         // 不存在时为 no-op；同样的遮蔽规则
+```
+
+`credentials/updated (ref)` 在 provider 管理的来源发生已提交变更后触发——`set`、`unset` 或在存储中观察到的外部编辑。进程环境变量的变化不可观测，永不触发。消费方不需要该事件（它们按操作重新解析）；它服务于配置界面刷新"已配置"徽标。
+
+`set`/`unset` 的遮蔽规则是刻意的 fail-loud：当只读来源（本地 provider 中即活跃进程环境）正在提供该引用时，写入会表面成功而解析仍返回遮蔽值——seam 选择直接拒绝，并通过 `describe().writable` 让界面提前把该引用渲染为只读。
+
+## Providers
+
+[`dsh-credentials-local`](../credentials-local/README.md) 把活跃进程环境叠加在 `$DSH_HOME/.env` 文件之上。seam 形状为 keyring、辅助命令、KMS 后端的 provider 留好了位置；远端 settings provider 永远不必携带秘密。
+
+## Model Experience
+
+Indirectly: a resolved value authorizes provider requests; the consuming adapter owns every model-visible surface.
+
+#### KV Cache effect
+
+No direct invalidation; credentials never enter a request prefix.
+
+## Known Limitations and Deferred Work
+
+- **不提供枚举**——seam 只回答被问到的引用；配置界面从 settings schema 得知引用集合，`list()` 没有当前消费者。
+- **引用限定为环境变量形状**——在有 provider 需要更丰富寻址前，保持单一扁平的 POSIX 标识符命名空间。
+- **进程环境变化不可见**——不可能为其发事件；界面只能在自身导航时重新读取 `describe()`。

Subject: [PATCH 003/102] feat(credentials): file-backed provider layering
 process env over $DSH_HOME/.env

Live environment wins read-only (shadowed writes reject instead of
appearing to succeed); the file is the writable source with byte-preserving
line edits, a quoting ladder dotenv reads back verbatim, atomic 0600
writes, wholesale snapshot replacement on reload, and write-drain
teardown.

+# dsh-credentials-local
+
+English | [中文](README.zh.md)
+
+File-backed [credentials](../credentials/README.md) provider: two layers, one honest precedence.
+
+| Layer | Source id | Writable | Wins |
+|---|---|---|---|
+| Live process environment | `env` | no | always |
+| `$DSH_HOME/.env` document | `file` | yes (`set`/`unset`) | otherwise |
+
+The environment wins because a launch-time override (`DEEPSEEK_API_KEY=… dsh`, CI secrets, a dev shell sourcing the repo `.env`) is operator intent for this run — and because it cannot be edited from inside, it must be *visibly* read-only: `describe()` reports `source: 'env', writable: false`, and `set`/`unset` reject instead of writing a change the reader would never see. Resolution reads `process.env` live and never writes it back.
+
+## Config
+
+| Field | Default | Meaning |
+|---|---|---|
+| `path` | `<harness home>/.env` | Credentials document location. |
+| `dshHome` | `$DSH_HOME` or `~/.dsh` | Harness home used when `path` is omitted. |
+| `watch` | `true` | Hot-publish external edits. |
+| `debounceMs` | `100` | Watcher write-settle window. |
+
+## The document
+
+dotenv format, parsed with `dotenv` and edited by a line editor that preserves every byte it does not own: `set` rewrites the first assignment of its key in place (dropping later duplicates, which dotenv's last-wins reading would otherwise let override the edit), `unset` removes only the owning line, comments and unrelated lines survive verbatim. Writes go through [`dsh-atomic-write`](../../util/atomic-write/README.md) with mode `0600`.
+
+Values are rendered in the narrowest style dotenv reads back verbatim — bare, then single-quoted (fully literal), then double-quoted (only without backslashes, which double-quote reading expands). A value no style can represent, and any entry that already spans multiple physical lines, fails loud instead of being corrupted silently. An empty stored value is absent, per the seam rule.
+
+## Hot reload
+
+External edits publish `credentials/updated` per changed reference after the snapshot is replaced **wholesale** — an entry deleted on disk never lingers in memory. The provider's own writes are recognized by content and publish exactly their one commit event. An unreadable document at runtime keeps the last good snapshot and warns; an absent file is an empty store; an unreadable file at boot fails loud. Keys that are not POSIX identifiers are preserved file content the seam cannot address.
+
+## Model Experience
+
+Indirectly: resolved values authorize LLM adapter requests; the consuming adapter owns every model-visible surface.
+
+#### KV Cache effect
+
+No direct invalidation; credentials never enter a request prefix.
+
+## Known Limitations and Deferred Work
+
+- **Multi-line entries refuse `set`/`unset`** — the line editor will not rewrite an entry it would corrupt; edit the file directly.
+- **Unrepresentable values fail loud** — control characters, or a mix of both quote styles with backslashes, cannot round-trip the dotenv line format.
+- **Environment changes are invisible** — `process.env` is read live per resolution, but no event can announce a change there.
+- **Atomic, not crash-durable** — inherited from `dsh-atomic-write`; the store re-reads on boot.

+# dsh-credentials-local
+
+[English](README.md) | 中文
+
+文件型[凭据](../credentials/README.zh.md) provider：两层来源，一条诚实的优先级。
+
+| 层 | 来源 id | 可写 | 优先 |
+|---|---|---|---|
+| 活跃进程环境 | `env` | 否 | 恒定优先 |
+| `$DSH_HOME/.env` 文档 | `file` | 是（`set`/`unset`） | 其余情况 |
+
+环境优先，因为启动时注入（`DEEPSEEK_API_KEY=… dsh`、CI secrets、加载了仓库 `.env` 的开发 shell）代表本次运行的操作者意图——而它无法从进程内部修改，就必须**可见地**只读：`describe()` 报告 `source: 'env', writable: false`，`set`/`unset` 直接拒绝，而不是写下一个读取方永远看不到的变更。解析实时读取 `process.env`，绝不写回。
+
+## 配置
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `path` | `<harness home>/.env` | 凭据文档位置。 |
+| `dshHome` | `$DSH_HOME` 或 `~/.dsh` | `path` 缺省时使用的 harness home。 |
+| `watch` | `true` | 热发布外部编辑。 |
+| `debounceMs` | `100` | watcher 写入沉降窗口。 |
+
+## 文档本身
+
+dotenv 格式，用 `dotenv` 解析；写回用行级编辑器，保留一切不属于本次编辑的字节：`set` 原位改写该键的第一条赋值行（丢弃后续重复行——dotenv 按最后一条生效，重复行会反过来覆盖这次编辑），`unset` 只删除所属行，注释与无关行逐字保留。落盘经 [`dsh-atomic-write`](../../util/atomic-write/README.zh.md)，权限 `0600`。
+
+值按 dotenv 能逐字读回的最窄样式渲染——裸值，其次单引号（完全字面），再次双引号（仅限无反斜杠，双引号读取会展开转义）。任何样式都无法表示的值、以及已经跨越多个物理行的条目，响亮失败而不是被静默破坏。空的存储值等于不存在（seam 规则）。
+
+## 热重载
+
+外部编辑在快照**整体替换**后按变更引用逐个发布 `credentials/updated`——磁盘上删掉的条目绝不在内存滞留。provider 自己的写入按内容识别，只发布属于该次提交的一个事件。运行期文档不可读时保留最后一份好快照并告警；文件不存在即空存储；启动时不可读则响亮失败。非 POSIX 标识符的键属于被保留的文件内容，seam 无法寻址。
+
+## Model Experience
+
+Indirectly: resolved values authorize LLM adapter requests; the consuming adapter owns every model-visible surface.
+
+#### KV Cache effect
+
+No direct invalidation; credentials never enter a request prefix.
+
+## Known Limitations and Deferred Work
+
+- **多行条目拒绝 `set`/`unset`**——行编辑器不改写会被它破坏的条目；请直接编辑文件。
+- **无法表示的值响亮失败**——控制字符，或同时混用两种引号又含反斜杠的值，无法在 dotenv 行格式中往返。
+- **环境变化不可见**——每次解析实时读取 `process.env`，但那里的变化不可能发出事件。
+- **原子但不保证崩溃持久**——继承自 `dsh-atomic-write`；存储在启动时重新读取。

Subject: [PATCH 004/102] feat(llm-deepseek): per-request connection resolution
 over settings + credentials

The adapter takes an options thunk and a per-stream credential resolver
instead of frozen construction facts: base URL, catalog, defaults, idle
budget, and the API key re-resolve at each operation, so a settings or
credential change reaches the very next request while in-flight streams
keep the facts they started with. resolveAdapterOptions is the one explicit
resolve step (entry config fails loud at load; a live snapshot failing a
beyond-schema bound keeps the last good options). The plugin layers its
entry config under the optional llm-deepseek settings section and resolves
keys literal-first through ctx.credentials with an ambient env fallback; a
missing key now registers the route, warns, and fails each request with
actionable MISSING_CREDENTIAL instead of failing plugin load. The
registration-captured retry policy re-registers the route in place when it
changes.

+ * load: the plugin layers its `cordis.yml` entry config under the optional
+ * `llm-deepseek` user-settings section (`ctx.settings`) and resolves the API

+ * anything, while an in-flight stream keeps the facts it started with. The
+ * one registration-captured fact — the retry policy — re-registers the route
+ * in place when it changes.

Subject: [PATCH 005/102] feat(llm-pi-ai): route-keyed profiles with
 per-request resolution and in-place route swaps

providers becomes a dict keyed by provider route, so the composition base
and the llm-pi-ai settings section merge per provider and the route set is
structural; the pre-release array shape and per-profile provider field fail
loud with migration directions. The adapter reads a profiles thunk once per
operation and resolves the credential per stream call (literal apiKey, then
apiKeyEnv through ctx.credentials with an ambient env fallback, then pi-ai's
provider-native discovery), so key, endpoint, and knob changes reach the
next request without restarts. Route-set or captured-retry-policy changes
re-register the same adapter instance in one synchronous section; an invalid
settings snapshot keeps the last good profiles.

From d77db29f01e798dcef9dcab7edf1fff95bfddbdb Mon Sep 17 00:00:00 2001
From: Yichen Jiang <jyc132780208@sina.com>
Date: Wed, 29 Jul 2026 13:44:24 +0800
Subject: [PATCH 006/102] test: real-Loader dynamic composition, keyless
 onboarding snapshot, and .env-only e2e

llm-deepseek gains a Loader+Include composition spec proving external
settings.yaml/.env edits reach the very next request, and a real-API e2e
where only a credentials-local document holds the key. The headless example
pins the first-run missing-credential UX as a keyless stream-json snapshot
(new credentials.cordis.snapshot.yml scenario); runLoaderSmoke learns
expectedExitCode so a designed failure surface can be pinned instead of
masked.

+# Agent Note: request-level LLM configuration and the credential seam
+
+Status: implemented
+
+English | [中文](2026-07-29-request-level-llm-config-credentials.zh.md)
+
+> Scope: the first production consumers of `ctx.settings` (the two LLM adapter plugins), the new `packages/credentials/` capability family, and the `packages/util/atomic-write` extraction. The follow-up wire surface (`settings.*`/`credentials.*` RPC, secret-role masking, the web settings form) is a separate PR and not part of this note's shipped scope.
+
+## Problem
+
+The [settings seam](2026-07-28-user-settings-seam.md) shipped without a production consumer, and the LLM adapters were the motivating one: both froze `apiKey`/`baseURL`/catalog into adapter instances at plugin load, so a changed key or endpoint needed a process restart, and a missing key failed plugin load — the worst possible first-run posture for a personal config page ("store a key, then restart"). Secrets were also headed the wrong way: the natural move (put `apiKey` in the settings document) would have forced masking, server-side backfill on `replace`, and dotfiles-sync warnings, a mitigation stack for a problem peer products simply do not have — Codex (`env_key` + auth.json), Reasonix (`api_key_env` + home `.env`), OpenCode/Pi (`auth.json`), Claude Code (`apiKeyHelper`) all keep secrets out of configuration files.
+
+## Decision
+
+**Per-request resolution, not fiber rebuilds.** The adapters take an options thunk (and a per-stream credential resolver) instead of frozen construction facts, resolving once per operation — the Pi pattern, with its tested semantics: two requests straddling a change see two configurations, one request resolves exactly once, and an in-flight stream keeps the facts it started with. This deletes the entire swap machinery a rebuild design needs (`DUPLICATE_ADAPTER` ordering, `NO_ADAPTER` windows, a deferred-activation state machine) and makes a missing key a *request-time* actionable failure (`MISSING_CREDENTIAL` naming every entry point) while the route stays registered and the catalog stays browsable. The one registration-captured fact — the retry policy the `ctx.llm` registry snapshots at `registerAdapter` (plus pi-ai's route *set*) — re-registers the same adapter instance in one synchronous section when it changes.
+
+**Secrets are references, values live behind `ctx.credentials`.** Configuration (both planes) carries `apiKeyEnv: DEEPSEEK_API_KEY`; the three-package credential seam resolves it per operation. `credentials-local` layers the live process environment (read-only, wins — a launch-time override is operator intent and must be *visibly* read-only, so shadowed writes reject instead of appearing to succeed) over `$DSH_HOME/.env` (writable, byte-preserving line edits, a quoting ladder dotenv reads back verbatim, wholesale snapshot replacement on reload so a deleted entry never lingers — the Claude Code additive-reapply lesson). Resolution order in the adapters is literal `apiKey` first (preserving the historical `config.apiKey ?? env` observable semantics), then the seam, then — only without a mounted seam — the raw environment variable.
+
+**Per-plugin namespaces, schema ≡ `Config`.** Each adapter registers its own namespace (`llm-deepseek`, `llm-pi-ai`) with its plugin `Config` schema and its `cordis.yml` entry as the composition `base` — a settings section is the same YAML shape as the entry config, and `resolveAdapterOptions`/`resolveProfiles` stay the one explicit resolve step for both. A live snapshot failing a beyond-schema bound keeps the last good facts (the seam's last-good philosophy extended one level up); the entry config itself still fails load. pi-ai's `providers` became a dict keyed by route so base and user layers merge per provider and the route set is structural; the array shape fails loud with migration directions.
+
+## Alternatives considered
+
+- **A bridge plugin (`dsh-llm-models`) owning one unified `models` dict** — with per-plugin namespaces there is nothing left to bridge, and the adapter-mapping rules it needed were pure invented indirection.
+- **Secrets in settings.yaml under `role('secret')` masking** — deleting the problem (references) beats mitigating it (mask + backfill + sync warnings); the coding-agent cohort is unanimous.
+- **Registry-level live retry policy** — making `providerRetryPolicy` re-read per call would silently change the `ctx.llm` capture contract every registration relies on; re-registering the route in place keeps that contract and stays observable.
+
+## Consequences
+
+Onboarding is restart-free end to end (pinned by the `missing-credential` headless snapshot and the credentials-rotation composition tests): boot keyless, browse the catalog, store the key, prompt again. The demos mount `settings-local` + `credentials-local` by default and inline no `!!js` key plumbing. `runLoaderSmoke` gained `expectedExitCode` so a designed failure surface can be pinned rather than masked. Deferred: the wire/UI surface must redact `role('secret')` fields before any RPC exposes `describe()`, settings-layer arrays still replace wholesale (the deepseek `models` list), and a settings section cannot remove a composition-provided pi-ai route (only override or extend).

+# Agent Note：请求级 LLM 配置与凭据 seam
+
+Status: implemented
+
+[English](2026-07-29-request-level-llm-config-credentials.md) | 中文
+
+> 范围：`ctx.settings` 的第一批生产消费方（两个 LLM 适配器插件）、新增的 `packages/credentials/` 能力族，以及 `packages/util/atomic-write` 的抽取。后续的 wire 面（`settings.*`/`credentials.*` RPC、secret 角色脱敏、web 设置表单）是单独的 PR，不在本 note 已交付范围内。
+
+## 问题
+
+[settings seam](2026-07-28-user-settings-seam.md) 落地时没有生产消费方，而 LLM 适配器正是当初驱动该 seam 的那个消费方：两个适配器都在插件加载时把 `apiKey`/`baseURL`/catalog 冻结进适配器实例，改密钥或端点就要重启进程，密钥缺失则直接使插件加载失败——对个人配置页而言，这是最糟糕的首次运行姿态（「先存密钥，再重启」）。机密的走向也不对：顺理成章的做法（把 `apiKey` 放进设置文档）会被迫引入脱敏、`replace` 时的服务端回填与 dotfiles 同步告警，为一个同类产品根本没有的问题堆起一整摞缓解措施——Codex（`env_key` + auth.json）、Reasonix（`api_key_env` + 家目录 `.env`）、OpenCode/Pi（`auth.json`）、Claude Code（`apiKeyHelper`）全都把机密挡在配置文件之外。
+
+## 决策
+
+**按请求解析，而非重建 fiber。**适配器改为接收一个 options thunk（外加按流调用的凭据解析器），不再持有冻结的构造期事实，每个操作解析一次——即 Pi 的模式，连同其经测试固定的语义：跨越一次变更的两个请求看到两份配置，一个请求恰好解析一次，进行中的流保持其起始事实。这删掉了重建式设计所需的整套切换机制（`DUPLICATE_ADAPTER` 顺序问题、`NO_ADAPTER` 窗口、延迟激活状态机），并把密钥缺失变成*请求时*可行动的失败（`MISSING_CREDENTIAL` 点名每个配置入口），同时路由保持注册、catalog 保持可浏览。唯一在注册期捕获的事实——`ctx.llm` 注册表在 `registerAdapter` 时快照的重试策略（外加 pi-ai 的路由*集合*）——在其变化时于一个同步区段内原地重新注册同一适配器实例。
+
+**机密是引用，值藏在 `ctx.credentials` 背后。**配置（两个面）携带 `apiKeyEnv: DEEPSEEK_API_KEY`；三包凭据 seam 按操作解析它。`credentials-local` 把活跃进程环境（只读、优先——启动时覆盖是操作者意图，必须*可见地*只读，因此被遮蔽的写入直接拒绝而不是表面成功）叠加在 `$DSH_HOME/.env` 之上（可写、保字节行级编辑、dotenv 能逐字读回的引号阶梯、重载时整体替换快照使删除的条目绝不滞留——来自 Claude Code 增量重放（additive reapply）的教训）。适配器内的解析顺序为：字面 `apiKey` 优先（保留历史 `config.apiKey ?? env` 的可观察语义），然后是 seam，最后——仅在未挂载 seam 时——原始环境变量。
+
+**按插件划分 namespace，schema ≡ `Config`。**每个适配器注册自己的 namespace（`llm-deepseek`、`llm-pi-ai`），schema 用其插件 `Config` schema，组合 `base` 用其 `cordis.yml` 条目——settings 分节与 entry 配置是同一种 YAML 形状，`resolveAdapterOptions`/`resolveProfiles` 对两者仍是唯一的显式 resolve 步骤。存活快照若违反 schema 之外的约束，则保留最后可用事实（seam 的最后可用值哲学向上延伸一层）；entry 配置本身仍会加载失败。pi-ai 的 `providers` 改为以路由为键的字典，base 层与用户层因此按提供方合并，路由集合也由结构直接表达；数组形状响亮失败并给出迁移指引。
+
+## 曾考虑的替代方案
+
+- **由桥接插件（`dsh-llm-models`）持有统一的 `models` 字典**——有了按插件划分的 namespace，就没有什么可桥接的了；它所需的适配器映射规则纯属凭空发明的间接层。
+- **把机密放进 settings.yaml 并靠 `role('secret')` 脱敏**——删除问题本身（引用）胜过缓解问题（脱敏 + 回填 + 同步告警）；编码 agent 同类产品在这一点上口径一致。
+- **注册表级的实时重试策略**——让 `providerRetryPolicy` 每次调用都重读，会静默改变所有注册都依赖的 `ctx.llm` 捕获契约；原地重新注册路由既保住该契约，又保持可观察。
+
+## 后果
+
+上手流程端到端免重启（由 `missing-credential` headless 快照与凭据轮换组合测试固定）：无密钥启动、浏览 catalog、存入密钥、再次发起提示。demo 默认挂载 `settings-local` + `credentials-local`，不再内联任何 `!!js` 密钥接线。`runLoaderSmoke` 新增 `expectedExitCode`，使按设计出现的失败面可以被固定而非被掩盖。延后事项：wire/UI 面在任何 RPC 暴露 `describe()` 之前必须对 `role('secret')` 字段脱敏；settings 层的数组仍整体替换（deepseek 的 `models` 列表）；settings 分节无法移除组合提供的 pi-ai 路由（只能覆盖或扩展）。

 Abstract filesystem provider. Targets must preserve identity across aliases; reads expose regular UTF-8 text or typed errors, listings are stable and content-free, and mutations are atomic. Optional guards add stale protection without changing the unguarded provider contract.

+# User Credentials
+
+English | [中文](credentials.zh.md)
+
+The credential seam of [dsh-credentials](../../packages/credentials/credentials) keeps secrets out of configuration: settings sections and `cordis.yml` entries carry *references* (environment-variable names), providers such as [dsh-credentials-local](../../packages/credentials/credentials-local) own the values, and consumers resolve a reference once per operation — the LLM adapters resolve once per model request, so a rotated credential reaches the very next request without any restart. One seam-wide rule binds every provider: an empty stored value is absent everywhere.
+
+Source: [`packages/credentials/credentials/src/index.ts`](../../packages/credentials/credentials/src/index.ts)
+
+## Identity
+
+A reference names one credential as a POSIX-style environment-variable name. The brand keeps references from mixing with other cross-boundary strings; construction validates the shell-identifier shape.
+
+```ts type-equiv
+/** Nominal reference to one credential: a POSIX-style environment-variable name. */
+type CredentialRef = Branded<'CredentialRef'>
+```
+
+## Resolution
+
+`resolve(ref)` returns the value with the provider-defined source layer that supplied it, or `undefined` while unconfigured. Consumers re-resolve at each operation and never cache across operations — that per-operation read is the hot-update mechanism.
+
+```ts type-equiv
+/** One resolved credential value and the source layer that supplied it. */
+interface ResolvedCredential {
+  /** The non-empty secret value. */
+  value: string
+  /** Provider-defined source layer id (the local provider uses `env` and `file`). */
+  source: string
+}
+```
+
+## Description
+
+`describe(ref)` answers configuration surfaces without ever exposing a value: whether the reference resolves, from which layer, and whether `set` would currently succeed. The local provider reports a reference supplied by the live process environment as `writable: false` — a write would appear to succeed while resolution kept returning the shadowing value, so the seam rejects it and the UI can render the reference read-only up front.
+
+```ts type-equiv
+/** Source and writability facts for one reference, safe for configuration UIs — never the value. */
+interface CredentialInfo {
+  /** Whether {@link Credentials.resolve} would currently return a value. */
+  configured: boolean
+  /** Source layer currently supplying the value; absent while unconfigured. */
+  source?: string
+  /** Whether {@link Credentials.set} would currently succeed for this reference. */
+  writable: boolean
+}
+```
+
+## Change commits
+
+`credentials/updated (ref)` fires after a committed change to a provider-managed source — a `set`, an `unset`, or an external edit observed in storage. Ambient process-environment changes are not observable and never emit. Consumers do not need the event (they re-resolve per operation); it exists for configuration surfaces refreshing a "configured" badge.

+[dsh-credentials](../../packages/credentials/credentials) 的凭据 seam 把机密挡在配置之外：settings 分节与 `cordis.yml` 条目携带的是*引用*（环境变量名），值归 [dsh-credentials-local](../../packages/credentials/credentials-local) 这类 provider 所有，消费方每个操作解析一次引用——LLM 适配器每次模型请求解析一次，因此轮换后的凭据无需任何重启即可作用于紧随其后的下一次请求。一条 seam 级规则约束每个 provider：空的存储值在任何地方都视为不存在。

+
+引用以 POSIX 风格环境变量名命名一条凭据。brand 使引用不与其他跨边界字符串混用；构造时校验 shell 标识符形态。
+
+```ts type-equiv
+/** Nominal reference to one credential: a POSIX-style environment-variable name. */
+type CredentialRef = Branded<'CredentialRef'>
+```
+
+## 解析
+
+`resolve(ref)` 返回值，连同供出该值、由 provider 定义的来源层；未配置期间返回 `undefined`。消费方在每个操作中重新解析，绝不跨操作缓存——这次按操作进行的读取正是热更新机制。
+
+```ts type-equiv
+/** One resolved credential value and the source layer that supplied it. */
+interface ResolvedCredential {
+  /** The non-empty secret value. */
+  value: string
+  /** Provider-defined source layer id (the local provider uses `env` and `file`). */
+  source: string
+}
+```
+
+## 描述
+
+`describe(ref)` 在绝不暴露值的前提下回应配置界面：引用当前是否可解析、来自哪一层、`set` 当前能否成功。本地 provider 把由活跃进程环境供值的引用报告为 `writable: false`——那样的写入会表面成功而解析持续返回遮蔽值，因此 seam 直接拒绝，界面也得以提前把该引用渲染为只读。
+
+```ts type-equiv
+/** Source and writability facts for one reference, safe for configuration UIs — never the value. */
+interface CredentialInfo {
+  /** Whether {@link Credentials.resolve} would currently return a value. */
+  configured: boolean
+  /** Source layer currently supplying the value; absent while unconfigured. */
+  source?: string
+  /** Whether {@link Credentials.set} would currently succeed for this reference. */
+  writable: boolean
+}
+```
+
+## 变更提交
+
+`credentials/updated (ref)` 在 provider 管理的来源发生已提交变更后触发——`set`、`unset` 或在存储中观察到的外部编辑。进程环境自身的变化不可观测，永不发出事件。消费方不需要该事件（它们按操作重新解析）；它服务于配置界面刷新「已配置」徽标。

+The credential capability seam, as three-package shape dictates (interface / implementation / consumers):
+
+| Package | Role |
+|---|---|
+| [`credentials/`](credentials/README.md) | Abstract `ctx.credentials`: branded `CredentialRef` references, per-operation `resolve`, UI-safe `describe`, fail-loud `set`/`unset`, the `credentials/updated` commit event |
+| [`credentials-local/`](credentials-local/README.md) | File/environment provider: the live process environment (read-only, wins) layered over `$DSH_HOME/.env` (writable, byte-preserving line edits, hot-reloaded) |
+
+Configuration files carry *references* to secrets (`apiKeyEnv: DEEPSEEK_API_KEY`), never the secrets: the settings document stays safe to sync and render, and rotating a value touches no configuration. The LLM adapters are the first consumers — they resolve their reference once per model request, which is what makes a key stored moments ago reach the very next request without restarting anything.
+
+The seam shape leaves room for keyring-, helper-command-, and KMS-backed providers.

 `streamIdleTimeoutMs` bounds each outstanding provider read, including the initial `fetch`, without counting time the consumer spends between chunks. One stable abort signal reaches the request and body reader for the whole call; expiry stops the transport and throws `LlmError('TIMEOUT')`, while an earlier caller abort throws `LlmError('ABORTED')`. The adapter makes exactly one provider request per `stream()` call; it registers the configured policy as provider metadata, and `dsh-llm-retry` separately executes it at durable agent-step boundaries.
 
+## Dynamic configuration (settings + credentials)
+
+Connection facts are not frozen at load. `resolveAdapterOptions` is the one explicit resolve step from raw config to validated facts, and the adapter re-reads them through a thunk **once per operation**: base URL, catalog, request defaults, and idle budget all take effect on the next request, while an in-flight stream keeps the facts it started with. Two optional seams feed that thunk:
+
+- **`ctx.settings`** — the plugin registers the `llm-deepseek` namespace with this same `Config` schema and its `cordis.yml` entry as the composition `base`, so a `llm-deepseek:` section in the user settings document overrides any field without a restart. Without a mounted settings service the entry config alone drives the adapter, unchanged. A live settings snapshot that passes the schema but fails a beyond-schema bound (a duplicate catalog id, a broken thinking/effort pair) keeps the last good facts and logs the failure; the entry config itself still fails plugin load.
+- **`ctx.credentials`** — the API key resolves per stream call: a non-empty literal `apiKey` wins, then `apiKeyEnv` through the credential seam (`$DSH_HOME/.env` under the live environment), then — only without a mounted seam — the raw environment variable. A request with no key anywhere fails with `MISSING_CREDENTIAL` naming every configuration entry point, while the route stays registered and the catalog stays browsable — first-run onboarding is "browse models, store the key, prompt again", with no restart between.
+
+The one registration-captured fact is the retry policy: when its resolved value changes, the plugin re-registers the route in place (same adapter instance, one synchronous section), so `ctx.llm.providerRetryPolicy('deepseek')` always reports the current policy.
+
 ## App attribution
 
 Every request carries the shared attribution header from dsh-llm's `attributionHeaders()` - the mandatory `User-Agent` baseline identifying the harness (see [dsh-llm § App attribution](../llm/README.md#app-attribution-attributionts)). Direct DeepSeek requests and OpenAI-compatible gateway requests get no provider-specific app-attribution headers under this adapter contract; OpenRouter app attribution is deferred to a future explicit OpenRouter adapter or mode. A request whose `GenerateOptions.purpose` is `compaction` (dsh-compact-basic's auxiliary summarization call) additionally carries `x-deepseek-harness-compact: 1`, so the host can separate compaction traffic from conversation requests.

+- **A settings `models` list replaces the composition list wholesale** — settings-layer merging is per-field, and arrays are one field; per-entry catalog merging would need a keyed shape.
+- **`Config.apiKey` is schema-tagged `role('secret')` but not yet masked anywhere** — the settings `describe()` envelope returns values verbatim; the wire/UI layer that must redact secret-role fields ships with the settings RPC surface.
 - **`tool_choice` is not mapped** — not part of the core vocabulary (MVP cut, shared with the pi-ai twin).
 - **Requests use raw `fetch`, not `@cordisjs/plugin-http`** — no shared proxy/interception configuration; adoption is deferred until a second adapter wants it (`TODO(http)`).
 - **Serialization flattens user and tool-result content to text blocks** — plugin-added block types are skipped, and empty tool output crosses the wire as the literal `(no output)`.

One plugin instance owns a dict of provider profiles keyed by route; every request selects a profile with `GenerateOptions.provider` and resolves `GenerateOptions.model` dynamically from pi-ai's installed catalog.
 
 The package root exposes the Cordis plugin contract and `PiAiAdapter`; profile resolution, model construction, replay conversion, and stream conversion remain package-internal.

+Each dict key must exist in pi-ai's installed catalog; the dict shape makes duplicates unrepresentable, and the pre-release array shape (with per-profile `provider` fields) fails load with migration directions. Registration with `ctx.llm` is atomic: a collision with any provider route already owned by another adapter fails plugin loading without registering the remaining routes. Model ids are not lifecycle config; an unknown model fails before any provider request with `LlmError('UNKNOWN_MODEL')`.
+
+## Dynamic configuration (settings + credentials)
+
+The adapter reads its profiles through a thunk **once per operation** instead of freezing them at construction. The plugin registers the `llm-pi-ai` namespace on the optional `ctx.settings` seam with this same `Config` schema and its `cordis.yml` entry as the composition `base`, and because `providers` is a dict, the base and the user's `llm-pi-ai:` settings section merge **per provider**: a user can add a route, override one field of a composition route, or point a route at another proxy, all effective on the next request with no restart. Without a mounted settings service the entry config alone drives the adapter, unchanged.
+
+Credentials resolve per stream call: a non-empty literal `apiKey` wins, then `apiKeyEnv` through the optional `ctx.credentials` seam (`$DSH_HOME/.env` under the live environment; the raw environment variable without a mounted seam), then pi-ai's ambient discovery. The route set and each route's captured retry policy are the registration-level facts: when either changes, the plugin re-registers the same adapter instance in one synchronous section, so `ctx.llm.listProviders()` and `providerRetryPolicy()` always reflect the current configuration. A live settings snapshot naming an unknown provider (or failing any other resolver bound) keeps the last good profiles and logs the failure; the entry config itself still fails plugin load.
 
 The adapter exposes each configured provider's installed pi-ai models through `ctx.llm.listModels(provider)`. This is provider-neutral selector metadata derived from `getModels(provider)`; request-time resolution still performs the authoritative catalog lookup, so discovery does not create a second model registry. `ctx.llm.resolveModelInfo(provider, model)` performs that exact descriptor lookup once and returns its identity, context window, and selectable thinking levels, keeping authoritative metadata on the route-owning adapter rather than its consumers.
 
 The `reasoning.efforts` list is pi-ai's ordered `getSupportedThinkingLevels(model)` result without filtering or normalization, including `off` and the model-specific availability of `xhigh` or `max`. The Harness exposes each canonical pi-ai level as an opaque ID; provider/model wire spellings remain inside pi-ai's `thinkingLevelMap`. A non-reasoning model therefore exposes pi-ai's `off` choice. The profile `reasoning` value, including `off`, is the deployment default when configured; omitting it preserves the provider default. Per-request `GenerateOptions.reasoningEffort` takes precedence, and any explicit value absent from the exact model capability fails with `UNSUPPORTED_REASONING_EFFORT` before network I/O instead of being clamped. pi-ai's common stream options represent `off` by omitting `reasoning`.
 
-Supported profile fields are `provider`, `apiKey`, `baseURL`, `headers`, `reasoning`, `thinkingBudgets`, `cacheRetention`, `transport`, `timeoutMs`, `websocketConnectTimeoutMs`, `streamIdleTimeoutMs`, and `retryPolicy`. Each profile's optional retry policy is captured with that provider route; omission uses bounded normal defaults. The stream-idle interval is a positive finite Node timer delay, defaults to five minutes, and covers only an outstanding provider read, not consumer think time. Harness app attribution wins a conflicting configured header name.

The removed profile fields `maxRetries` and `maxRetryDelayMs` fail load instead of silently multiplying or hiding the separately composed agent-level retry budget. Idle expiry aborts the SDK's stable request signal and surfaces `TIMEOUT`; an earlier caller abort remains `ABORTED`.

 ## Known Limitations and Deferred Work
 
+- **Settings can add or override routes, not remove composition routes** — the user layer merges over the composition `base`, so deleting a `cordis.yml`-provided provider is a composition change; `replace` on the namespace only resets the user layer.
+- **`apiKey` is schema-tagged `role('secret')` but not yet masked anywhere** — the settings `describe()` envelope returns values verbatim; the wire/UI layer that must redact secret-role fields ships with the settings RPC surface.
 - **Catalog membership is required** — custom model ids that are absent from the installed pi-ai catalog fail with `UNKNOWN_MODEL`, even when a provider profile supplies a custom endpoint.
 - **`GenerateOptions.stop` is unsupported** — pi-ai's common stream options cannot guarantee stop-sequence behavior across providers, so the adapter rejects the field.
 - **In-history `system` messages use pi-ai's common context conversion** — provider-specific placement follows pi-ai rather than a harness-owned wire override.

+
+## 动态配置（settings + credentials）
+
+适配器经由一个 thunk **每操作读取一次** profile，而非在构造期冻结。插件在可选的 `ctx.settings` seam 上用同一份 `Config` schema 注册 `llm-pi-ai` namespace，并以其 `cordis.yml` 条目为组合 `base`；由于 `providers` 是字典，base 与用户的 `llm-pi-ai:` settings 分节**按提供方**合并：用户可以新增路由、覆盖组合路由的单个字段，或把路由指向另一个 proxy，全部在下一次请求生效，无需重启。未挂载 settings 服务时，仅由 entry 配置驱动适配器，行为不变。
+
+凭据按每次 stream 调用解析：非空的字面 `apiKey` 优先，其次经可选的 `ctx.credentials` seam 解析 `apiKeyEnv`（活跃环境之下的 `$DSH_HOME/.env`；未挂载 seam 时为原始环境变量），最后是 pi-ai 的环境发现。路由集合与每条路由捕获的重试策略是注册级事实：两者任一变化时，插件都会在一个同步区段内重新注册同一适配器实例，因此 `ctx.llm.listProviders()` 与 `providerRetryPolicy()` 始终反映当前配置。存活 settings 快照若点名未知提供方（或违反任何其他 resolver 约束），则保留最后可用 profile 并记录失败；entry 配置本身仍会使插件加载失败。
 
 适配器通过 `ctx.llm.listModels(provider)` 公开每个已配置提供方已安装的 pi-ai 模型。这是从 `getModels(provider)` 派生的提供方无关 selector 元数据；请求时解析仍会执行权威 catalog 查找，因此发现不会创建第二个模型注册表。`ctx.llm.resolveModelInfo(provider, model)` 会执行一次精确 descriptor 查找，并返回其身份、上下文窗口和可选思考级别，让权威元数据保留在拥有路由的适配器上，而非消费方。
 
 `reasoning.efforts` 列表是 pi-ai 有序的 `getSupportedThinkingLevels(model)` 结果，不经筛选或规范化，其中包括 `off`，以及模型对 `xhigh` 或 `max` 的特定支持。Harness 将每个规范 pi-ai 级别公开为不透明 ID；提供方／模型协议拼写仍保留在 pi-ai 的 `thinkingLevelMap` 中。因此，不具备推理（reasoning）能力的模型也会公开 pi-ai 的 `off` 选项。配置 profile 的 `reasoning` 值（包括 `off`）在存在时是部署默认值；省略它会保留提供方默认值。每次请求的 `GenerateOptions.reasoningEffort` 优先；任何未出现在确切模型能力中的显式值都会在网络 I/O 前以 `UNSUPPORTED_REASONING_EFFORT` 失败，而不会被自动调整。pi-ai 的通用流选项通过省略 `reasoning` 表示 `off`。

Subject: [PATCH 008/102] fix(examples): drop the dev HMR row the native source
 launch cannot load
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Vendored @cordisjs/plugin-hmr uses decorators — non-erasable syntax the
--experimental-transform-types demo:tui launch refuses — so its row made the
shipped TUI composition unbootable from source while the tsx-launched
snapshot harness masked it. The stale !!js head comment goes with it;
restoring dev HMR is tracked separately.

An empty or omitted providers dict is now the valid dormant posture: the
adapter mounts with zero routes and no catalog entries, registers routes
the moment the llm-pi-ai settings section supplies profiles, and drops
them when it empties. The TUI demo mounts the adapter bare, so adding an
openai/anthropic provider is purely a settings.yaml (or, next PR, web
form) operation with per-request apiKeyEnv credential resolution.

 **Secrets are references, values live behind `ctx.credentials`.** Configuration (both planes) carries `apiKeyEnv: DEEPSEEK_API_KEY`; the three-package credential seam resolves it per operation. `credentials-local` layers the live process environment (read-only, wins — a launch-time override is operator intent and must be *visibly* read-only, so shadowed writes reject instead of appearing to succeed) over `$DSH_HOME/.env` (writable, byte-preserving line edits, a quoting ladder dotenv reads back verbatim, wholesale snapshot replacement on reload so a deleted entry never lingers — the Claude Code additive-reapply lesson). Resolution order in the adapters is literal `apiKey` first (preserving the historical `config.apiKey ?? env` observable semantics), then the seam, then — only without a mounted seam — the raw environment variable.
 
-**Per-plugin namespaces, schema ≡ `Config`.** Each adapter registers its own namespace (`llm-deepseek`, `llm-pi-ai`) with its plugin `Config` schema and its `cordis.yml` entry as the composition `base` — a settings section is the same YAML shape as the entry config, and `resolveAdapterOptions`/`resolveProfiles` stay the one explicit resolve step for both. A live snapshot failing a beyond-schema bound keeps the last good facts (the seam's last-good philosophy extended one level up); the entry config itself still fails load. pi-ai's `providers` became a dict keyed by route so base and user layers merge per provider and the route set is structural; the array shape fails loud with migration directions.

Subject: [PATCH 013/102] refactor(llm-deepseek)!: rename the provider route to
 deepseek-official

The native adapter's route was named deepseek, colliding with pi-ai's
catalog provider of the same name, so the two DeepSeek paths could never
be mounted side by side. The web settings page needs both configurable at
once. Compositions, fixtures, goldens, scaffolding defaults, and docs all
move together (pre-release, no shim); TUI/session-query-spill/
missing-credential goldens re-recorded through their keyless refresh
modes because provider-name length shifts box padding and spill
truncation points.

Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available.

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record<string, JsonValue>;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

+{"type":"request/header","seq":4,"time":1783957884564,"data":{"header":{"config":{"provider":"deepseek-official","model":"deepseek-v4-flash"},"system":"You are an AI agent powered by the DeepSeek Harness SDK.\n\nYou are headless-agent, a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record<string, JsonValue>;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record<string, JsonValue>;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record<string, JsonValue>;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined.

Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation.

Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

 - **`ctx.settings`** — the plugin registers the `llm-deepseek` namespace with this same `Config` schema and its `cordis.yml` entry as the composition `base`, so a `llm-deepseek:` section in the user settings document overrides any field without a restart. Without a mounted settings service the entry config alone drives the adapter, unchanged. A live settings snapshot that passes the schema but fails a beyond-schema bound (a duplicate catalog id, a broken thinking/effort pair) keeps the last good facts and logs the failure; the entry config itself still fails plugin load.
 - **`ctx.credentials`** — the API key resolves per stream call: a non-empty literal `apiKey` wins, then `apiKeyEnv` through the credential seam (`$DSH_HOME/.env` under the live environment), then — only without a mounted seam — the raw environment variable. A request with no key anywhere fails with `MISSING_CREDENTIAL` naming every configuration entry point, while the route stays registered and the catalog stays browsable — first-run onboarding is "browse models, store the key, prompt again", with no restart between.

 - **`ctx.settings`**——插件用同一份 `Config` schema 注册 `llm-deepseek` namespace，并以其 `cordis.yml` 条目为组合 `base`，因此用户设置文档中的 `llm-deepseek:` 分节可以免重启覆盖任何字段。未挂载 settings 服务时，仅由 entry 配置驱动适配器，行为不变。存活 settings 快照若通过 schema 却违反 schema 之外的约束（重复的 catalog id、无法成立的 thinking／推理强度组合），则保留最后可用事实并记录失败；entry 配置本身仍会使插件加载失败。
 - **`ctx.credentials`**——API 密钥按每次 stream 调用解析：非空的字面 `apiKey` 优先，其次经凭据 seam 解析 `apiKeyEnv`（活跃环境之下的 `$DSH_HOME/.env`），最后——仅在未挂载 seam 时——读取原始环境变量。任何地方都没有密钥的请求以 `MISSING_CREDENTIAL` 失败，并点名每个配置入口，同时路由保持注册、catalog 保持可浏览——首次运行的上手流程就是「浏览模型、存入密钥、再次发起提示」，中间无需任何重启。

 ### Real adapters
 
-Two adapters implement `LlmAdapter` on different internals: [`@deepseek-ai/dsh-llm-deepseek`](../llm-deepseek) uses direct fetch with `eventsource-parser` SSE framing for the `deepseek` route, while [`@deepseek-ai/dsh-llm-pi-ai`](../llm-pi-ai) dynamically resolves configured provider/model pairs through `@earendil-works/pi-ai`. Both follow the `StreamChunk` conventions in `types.ts`: usage precedes finish, tool arguments remain raw strings, and errors take one of two sanctioned paths. See [the twin LLM adapters](../../../.agents/notes/implemented/architecture/2026-06-13-twin-llm-adapters.md) for the design rationale.

-`inject: ['agents']`。服务器按 `sessionId` 获取或创建一个 agent。只有服务建立快照时的生命周期 `local` 标志为 true，服务器才会转发 subagent 完成事件；提供方名称、子级 id 和持久化谱系均不能证明本地性。已注册的适配器优先；未被持有的 `deepseek` 路由会挂载 `dsh-llm-deepseek`，任何其他未被持有的提供方都会导致初始化失败。其他功能由外围 `cordis.yml` 提供。

 `HarnessClient` retains discovered subagent ancestry for the lifetime of the runtime process. During each `Session.run()`, `TurnResult.notifications` and `on_notification` receive the root session and all known descendant notifications in wire order, including nested subagent lifecycle and session events. `TurnResult.events` remains the root session's complete event stream, and `TurnResult.final_response` is the text content from its last `assistant/message`; descendant messages therefore cannot replace the root response.

 `HarnessClient` 会在运行时进程的生命周期内保留已发现的 subagent（子 agent）祖先关系。每次执行 `Session.run()` 时，`TurnResult.notifications` 与 `on_notification` 会按线上的原始顺序收到根会话及所有已知后代的通知，其中包括嵌套 subagent 的生命周期与会话事件。`TurnResult.events` 仍只保存根会话的完整事件流，`TurnResult.final_response` 则取该会话最后一个 `assistant/message` 的文本内容，因此后代消息不会覆盖根会话回复。

Subject: [PATCH 014/102] feat(llm): topology event and configurable-provider
 directory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ctx.llm gains 'llm/adapters-updated' — a payload-free registry notification
emitted at every topology commit point (adapter routes registering or
disposing, directory entries appearing or withdrawing) with contained
observers and INVARIANT rethrow — plus registerConfigurableProviders/
listConfigurableProviders, the directory of routes an adapter plugin can
activate through configuration. llm-deepseek declares deepseek-official
(whole llm-deepseek section as profile); llm-pi-ai declares the full
installed catalog under providers.<provider> even while dormant, so the
web settings surface can offer every provider before any route exists.
The invariant companion asserts the registry stays readable at each
notification.

 The one registration-captured fact is the retry policy: when its resolved value changes, the plugin re-registers the route in place (same adapter instance, one synchronous section), so `ctx.llm.providerRetryPolicy('deepseek-official')` always reports the current policy.
 
+The plugin also declares its route in the configurable-provider directory (`ctx.llm.listConfigurableProviders()`): provider `deepseek-official`, settings namespace `llm-deepseek`, empty settings path — the whole section is the profile. Configuration surfaces use that entry to offer this adapter alongside dormant pi-ai providers.

 ## App attribution
 
 Every request carries the shared attribution header from dsh-llm's `attributionHeaders()` - the mandatory `User-Agent` baseline identifying the harness (see [dsh-llm § App attribution](../llm/README.md#app-attribution-attributionts)). Direct DeepSeek requests and OpenAI-compatible gateway requests get no provider-specific app-attribution headers under this adapter contract; OpenRouter app attribution is deferred to a future explicit OpenRouter adapter or mode. A request whose `GenerateOptions.purpose` is `compaction` (dsh-compact-basic's auxiliary summarization call) additionally carries `x-deepseek-harness-compact: 1`, so the host can separate compaction traffic from conversation requests.

 Provider and model metadata is a discovery surface, not a routing whitelist. `registerAdapter()` still owns provider exclusivity and captures the adapter's retry policy for each route, while an adapter may accept model ids absent from `listModels()`; consumers must not reject a request because its model is unlisted. Returned selector metadata is detached and invalid or duplicate adapter entries fail with `INVALID_ADAPTER` or `INVALID_CATALOG`.
 
+Every topology commit point — adapter routes registering or disposing, directory entries appearing or withdrawing — emits the payload-free `llm/adapters-updated` event after the mutation, so consumers re-read `listProviders()`/`listModels()`/`listConfigurableProviders()` instead of polling. Observer failures are contained (logged, non-vetoing); only `INVARIANT`-coded failures rethrow after the fan-out.
+
 Exact-model metadata is a separate correctness query, not a catalog decoration or global LLM setting. `resolveModelInfo()` asks the adapter that owns the exact provider/model route once; an adapter can describe an unlisted dynamic model, and absent `context` or `reasoning` fields mean only that those capabilities are unavailable. Invalid identity, context, or reasoning metadata fails with `INVALID_MODEL_INFO`, `INVALID_MODEL_CONTEXT`, or `INVALID_MODEL_REASONING`.
 
 Reasoning identifiers are opaque adapter-owned strings rather than a core enum. An adapter publishes its ordered selectable list, including an `off` id when that model's capability API exposes one. `resolveCallConfig()` accepts only an exact advertised identifier, materializes `defaultEffort` when present, and otherwise preserves the provider default. Asynchronous model resolvers receive the caller's signal and must settle promptly after cancellation. `prepareCall()` additionally retains the exact adapter registration through header logging and terminal dispatch, so HMR cannot combine one adapter's capability result with another adapter's request; reusing its one-shot handle or changing its call-config fields fails with `INVALID_PREPARED_CALL`. An unsupported explicit or configured effort fails with `UNSUPPORTED_REASONING_EFFORT` before provider I/O.

Subject: [PATCH 015/102] feat(settings): layered descriptors and structural
 secret redaction
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

describe() now carries each namespace's detached composition base and raw
user section beside the resolved value — presence in the user layer is how
a form marks a field user-overridden — and describe({redactSecrets:true})
strips role('secret') fields from every layer while enumerating their
{path,set} slots, so a wire surface has no slot that can carry a secret.
The pure redactSecrets(schema,value) walker (object/dict/array containers,
secret-role subtree as opaque leaf, inputs never mutated) is exported for
any other wire; the README's no-redaction Known Limitation is discharged.

 - `get(ns)` — resolved value, `undefined` while unregistered.
 - `update(ns, patch)` — deep-merges the plain-object patch into the user section only (never the `base`), validates the resolved candidate, persists through the provider, then commits. Validation failure rejects before anything is persisted; a read-only provider (`writable: false`) rejects every write. Writes to one namespace are serialized in call order.
 - `replace(ns, section)` — sets the user section wholesale: the removal/reset path a merge cannot express (`replace({})` re-inherits `base` and schema defaults).

 - **Cross-process concurrency is provider-defined** — the seam serializes writes per namespace in-process only; concurrent processes converge by provider behavior (the local file provider is last-write-wins).
-- **No secret-field redaction** — `describe()` returns resolved values verbatim; a wire surface (RPC/UI) must redact `role('secret')` fields before exposure.

Subject: [PATCH 016/102] feat(apiproxy): settings/credentials/llm wire
 domains, frames, and write guard

Eight compiler-locked methods: settings.describe/update/replace serve
redacted layered namespace views (secrets structurally absent from every
layer, write-only in the update direction) and fold seam refusals into
settings-rejected; credentials.describe/set/unset expose value-free views
with credential-rejected on shadowed writes; llm.providers merges the
configurable directory with live routes and llm.models claims the
host-scoped catalog reservation through the buildModelCatalog extraction
session.models now shares. Three HostFrame invalidations bridge the seam
events (host/settings-changed, host/credentials-changed,
host/models-changed), and the connection route generalizes the native-
dialog check into a privileged-method set covering all four writes. The
fixture and both fake clients grow the same face.

 The `command.*` and `skill.*` domains expose the host command registry and skill catalog to clients. Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `command.execute` runs a slash-command line host-side with pure admission semantics: the response reports whether the line resolved to a handler plus the minted lifecycle `commandId` when it did (correlating the acknowledgment with the flow node), while the outcome rides the durably logged `command/run`/`command/done` lifecycle pair broadcast on the mux stream; the carrier's request signal cancels the running handler. `host/commands-changed` is the catalog invalidation frame: clients refetch `command.list` instead of diffing.
 
+The `settings.*`, `credentials.*`, and `llm.*` domains are the configuration-page wire. `settings.describe` serves every registered namespace with its serialized schemastery schema plus redacted layered values (resolved/`base`/`user` — a field's presence in `user` marks it user-overridden) and the `secrets` slot list; `settings.update`/`settings.replace` write the user layer and answer with the namespace's new redacted view, folding every seam refusal into `settings-rejected`. Secret-role values never ride any response in any layer; a secret crosses the wire in exactly one direction — inside an `update` patch or `credentials.set`. `credentials.describe` returns value-free views (`configured`/`source`/`writable`), and `credentials.set`/`credentials.unset` map a shadowed-reference refusal onto `credential-rejected`. `llm.providers` merges the configurable-provider directory with live routes (dormant entries carry `active: false`; undeclared live routes append with no settings address) and `llm.models` is the session-independent catalog. Three invalidation frames keep every surface converged without polling: `host/settings-changed {ns}` (`settings/updated` passthrough — RPC writes and external `settings.yaml` edits alike), `host/credentials-changed {ref}` (reference names only, never values), and `host/models-changed` (`llm/adapters-updated` passthrough). The browser carrier restricts the four write methods (`settings.update`/`settings.replace`/`credentials.set`/`credentials.unset`) to loopback, same-origin requests — the `host.pickDirectory` privileged set. A composition without a settings or credential provider answers those domains with an actionable `internal` error naming the missing plugin.

 ## Carrier layer (`/client` + root)
 
 `AbstractApiClient` holds every protocol invariant — rpcId minting, envelope wrap/unwrap, zod parsing, SSE frame decoding, unary timeout, microtask-batched envelope observation (`subscribeEnvelopes`) — while platform subclasses supply only the `doFetch` transport aspect. `InProcessApiClient` over `toFetchHandler(api)` is the isomorphic point: the full wire serialization/validation path with no network, used by `dsh -p` headless.

 ## Known Limitations and Deferred Work
 
 - **`respond` routing is shipped, but pending-interaction state is host-side work** — the wire shape (POST `/api/respond`, `RpcReceipt`) is final; the pending table that makes late/duplicate answers meaningful lives in `src/api-proxy.ts` and is still minimal (questions only, no approvals).
-- **Reserved seams stay out of `RpcMethodMap`** — `session.fork`, `prompt.mode: 'inject'`, `task.list`, `host.listModels`, and a describe `hostInstanceId` are documented reservations; an unknown method fails loud at envelope parse rather than getting a not-implemented code.
+- **Reserved seams stay out of `RpcMethodMap`** — `session.fork`, `prompt.mode: 'inject'`, `task.list`, and a describe `hostInstanceId` are documented reservations (the former `host.listModels` reservation shipped as `llm.models`); an unknown method fails loud at envelope parse rather than getting a not-implemented code.
 - **No protocol version field** — client and host ship together; `host.describe` gains a version negotiation field only when an independently released client exists.
 - **Linux native picker requires desktop tooling** — `host.pickDirectory` reports an actionable error when neither Zenity nor KDialog is installed; it does not fall back to a custom or typed-path browser.

Subject: [PATCH 017/102] feat(schema-form): schema-driven React form renderer
 package

@deepseek-ai/dsh-client-schema-form rehydrates the wire's serialized
schemastery envelope (new Schema(json)) and edits a draft user section
against it: presence-in-draft marks a field overridden with a per-field
reset, inherited values render as placeholders, role('secret') slots are
write-only with configured-state placeholders from the wire's secrets
list, dict adds take a union-typed sKey as their vocabulary, and any
node the renderer cannot faithfully edit falls back to a read-only view
instead of silently disappearing. renderField(context) is the role hook
the Models page will use for the credential-ref control; validateDraft
runs the same rehydrated validator the host uses, so the browser and
host judge one schema.

+# @deepseek-ai/dsh-client-schema-form
+
+English | [中文](README.zh.md)
+
+Schema-driven React form renderer for settings sections. The wire's `settings.describe` carries each namespace's serialized schemastery schema (`schema.toJSON()` ref envelope); `SchemaForm` rehydrates it with `new Schema(json)` and renders every declared field as an editable control — the same schema object that validates a section on the host validates and drives the form in the browser, so there is no second form definition to drift.
+
+## Contract
+
+`SchemaForm` is a controlled component over a **draft user section**: `draft` is the object being edited (never mutated; every edit calls `onChange` with a new root), and `fallback` is the resolved value (schema defaults → composition base → user layer) used for inherited display. A field's presence in the draft marks it **overridden** and shows a per-field Reset that deletes the key, falling back to the inherited layer — presence semantics, not value comparison, exactly mirroring the settings seam's layering.
+
+Controls by schema node: `object` → labeled field groups (JSDoc `description` rendered, `required` starred), `string`/`number`/`boolean` → inputs with the inherited value as placeholder, `union` of literals → select whose empty option means "inherit", `array` → positional rows with add/remove (arrays replace wholesale on write), `dict` → keyed rows where a union-typed `sKey` becomes the add-select's vocabulary. `role('secret')` renders a **write-only** password input: the stored value never arrives (the wire strips it), and the `secrets` slot list (`{path, set}`) supplies the placeholder state. A node the renderer cannot faithfully edit (non-literal unions, transforms) renders a read-only JSON view with a notice instead of disappearing — a schema field is never silently dropped.
+
+`renderField(context)` is the role-aware override hook: return a node to replace the default control for one leaf. The Models settings page uses it to mount the credential-reference control (`role('credential-ref')`) that talks to `credentials.*` — this package stays wire-free and side-effect-free.
+
+`validateDraft(schema, draft)` runs the rehydrated validator and returns its failure message, letting pages validate before writing; the path helpers (`getPath`/`hasPath`/`setPath`/`deletePath`) expose the same immutable draft editing the controls use.
+
+## Model Experience
+
+None, as this package renders browser configuration forms; nothing here reaches a model request.
+
+#### KV Cache effect
+
+None; this package neither assembles nor sends a provider request.
+
+## Known Limitations and Deferred Work
+
+- **Validation is form-level, not per-field** — `validateDraft` reports schemastery's first failure message (which names the `$.path`); inline per-field error placement is deferred until a second consumer needs it.
+- **Strings are built-in English** — the `labels` prop overrides every user-visible string, but there is no locale-dictionary wiring inside this package; the embedding page owns localization.
+- **Non-literal unions and transforms render read-only** — faithful editing of those shapes needs per-shape controls; today they fall back to the JSON view with a notice.
+- **Array editing replaces wholesale** — element-level merge does not exist at the settings seam either; the form mirrors that contract rather than hiding it.

Subject: [PATCH 018/102] feat(ui-models): schema-driven provider configuration
 page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Models settings section joins llm.providers (the configurable
directory with live state), settings.describe (schemas, layered redacted
values, secret slots), and credentials.describe (value-free badges) into
provider rows with one editor card at a time. The editor renders the
provider's profile subtree through dsh-client-schema-form; the
credential-ref role mounts a control that shows configured/source state
and stores keys write-only through credentials.set. Apply without
removals merges a minimal patch (stored secrets outside it survive);
apply after a reset — and row deletion — replace the user section so
removals land. The client runtime bridges the three new host frames to
typed ctx events (settings/credentials/models changed), the page
refetches on any of them once loaded, and ui-model's per-session picker
directories reload on models/changed so a settings-born route appears in
open pickers without a reopen.

From 0d96676f3593b17541ff046ae93055ca3e17a6dd Mon Sep 17 00:00:00 2001

Subject: [PATCH 019/102] feat(web): mount the config plane in dsh web and pin
 the Models page keyless
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

apps/cli/cordis.yml gains settings-local, credentials-local, and the bare
dormant llm-pi-ai row (manifest deps added for the resolver contract);
llm-deepseek drops its !!js apiKey inline for per-request credential
resolution. Both adapters tag apiKeyEnv role('credential-ref') so the
form mounts the credential control. The web e2e scaffold isolates a
harness home per run — an in-process boot must never touch the
developer's real ~/.dsh — and the new models-settings scenario pins the
whole loop through the shipped app: dormant directory as add vocabulary,
schema-driven editor apply landing in settings.yaml, the route
registering live (topology frame), and a write-only key landing in the
temp .env with the configured badge converging. A hermetic test-owned
reference name keeps a developer's real provider keys from flipping the
badge. schema-form joins the platform module table (seed + externals)
so client bundles share one instance.

+# Agent Note: the web configuration plane
+
+Status: implemented

+
+> Scope: the wire face and web UI deferred from the [request-level LLM configuration note](2026-07-29-request-level-llm-config-credentials.md) — the `settings.*`/`credentials.*`/`llm.*` RPC domains with pushed invalidations, layered+redacted `describe()`, the llm configurable-provider directory and topology event, the standalone `dsh-client-schema-form` renderer, and the Models settings page. The `deepseek` → `deepseek-official` provider-route rename rides along as the enabling breaking change.
+
+## Problem
+
+PR1 made LLM adapter configuration restart-free at the seam, but the only writer was a text editor on `settings.yaml`: the web client had no wire access to settings, credentials, or provider topology, so "store a key, prompt again" still meant leaving the product. Three gaps blocked a config page rather than one: `describe()` returned only the merged effective value (a form cannot tell a user override from a composition default, and serializing it would have shipped `role('secret')` values to every browser), nothing enumerated the providers an adapter *could* run (a bare-mounted `llm-pi-ai` was invisible until configured), and the two adapters both wanted a `deepseek` route key, so the directory could not attribute routes to owning namespaces unambiguously. Hand-maintaining a form per provider was rejected outright — the schemas already exist as schemastery `Config` values, and a second source of field truth drifts.
+
+## Decision
+
+**Wire domains on the compiled RPC map, rejections as codes, invalidations as frames.** `settings.describe/update/replace`, `credentials.describe/set/unset`, `llm.providers`, and `llm.models` (claiming the reserved `host.listModels` surface) join `RpcMethodMap`, so the seven compiler-locked wiring sites keep contract, schema, handler, and client in lockstep. Seam rejections fold into `settings-rejected {ns}` / `credential-rejected {ref}` business errors (HTTP stays a carrier), and three `HostFrame`s — `host/settings-changed {ns}`, `host/credentials-changed {ref}`, `host/models-changed` — follow the `host/commands-changed` shape so every client converges without polling. Writes join `pickDirectory`/`openPath` in the connection guard's privileged set: loopback + same-origin or 403, because a LAN-exposed dsh web must not accept config mutation from another origin.
+
+**`describe()` grows layers and structural secret redaction.** `SettingsDescriptor` carries `base`/`user` beside the effective value, so the form marks "overridden" by presence in the user layer, not value inequality (an override *equal* to the base is still an override). `describe({ redactSecrets: true })` — mandatory at every wire face — strips `role('secret')` subtrees from all three layers via a pure structural walk of the schema (object/dict/array containers; a secret-role subtree is one opaque leaf) and enumerates the stripped slots as `{path, set}`, so a page can render write-only inputs without ever receiving a value.
+
+**The llm seam declares configurability and announces topology.** `registerConfigurableProviders()` is an all-or-nothing, fiber-scoped directory of `{provider, displayName, settingsNs, settingsPath}` — the addressing a config page needs to open the right settings subtree for a route that may not exist yet; `listConfigurableProviders()` merges with live routes in the wire handler so undeclared live routes still report active. The zero-payload `'llm/adapters-updated'` event fires from all four registration/unregistration commit points with contained listener dispatch (INVARIANT rethrow), following the settings/commands precedent. `llm-deepseek`'s route renamed to `deepseek-official` because the pi-ai catalog legitimately owns `deepseek` as an aggregator entry; pre-release stance, no alias.
+
+**A standalone schema-driven form renderer.** `dsh-client-schema-form` rehydrates the wire's `toJSON()` envelope into live schemastery nodes and renders by structural classification: objects/dicts/arrays recurse, all-literal unions become selects (an absent value shows `Default: X` from the fallback layer), dict key-unions feed the add-entry vocabulary, and anything it cannot faithfully edit renders as read-only JSON — visible, never dropped. Presence-in-draft drives the override badge and per-field Reset; a `renderField` hook lets consumers mount role-specific controls without the renderer knowing any role.
+
+**The Models page is a three-domain join with seam-shaped apply semantics.** Rows are configured providers; the add vocabulary is the dormant directory remainder; badges come from route liveness and the credential reference's value-free `configured` state. The `credential-ref` role mounts the credential control: reference name in settings, key value **write-only** through `credentials.set`. An edit without removals lands as a minimal `settings.update` merge patch (stored secrets outside the patch survive); a field reset or row deletion replaces the whole user section via `settings.replace`, because merge semantics cannot express removal.
+
+## Alternatives considered
+
+- **Serving JSON Schema over the wire** — schemastery's `toJSON()` envelope round-trips `role()`/meta and rehydrates into the validator the client already ships for drafts; converting to JSON Schema loses exactly the role annotations the credential control and secret redaction key on.
+- **Masking secrets per-field with sentinel backfill on `replace`** — the PR1 decision (secrets are references) already deleted the stored-literal case for the product default; structural redaction plus a write-only credential path handles the residue without teaching every writer a sentinel protocol.
+- **A `models` bridge plugin owning provider configuration** — same rejection as PR1: per-plugin namespaces plus a four-field directory declaration give the UI everything it needs; the bridge's unified dict re-imports the adapter-mapping indirection.
+- **Page-side polling instead of pushed frames** — the mux already carries `host/commands-changed`; three more frames cost one shape each and make a second tab, an external `settings.yaml` edit, and a settings-born route converge at event speed.
+
+## Consequences
+
+The whole loop is pinned keyless in the browser lane (`apps/web/tests/models-settings.e2e.ts`): the dormant pi-ai catalog renders as add vocabulary, adding `anthropic` writes `settings.yaml` and the route registers live on the topology frame, the key stores write-only into the harness home's `.env`, and the badge converges from the credentials frame — zero model calls, ARIA goldens for the empty and configured states, plus a scaffold `harnessHome` so tests never touch a real `~/.dsh`. The rename touched 239 files (fixtures, goldens, docs, python) in one commit with no compatibility alias. Deferred: a per-row models preview (the picker already lists models), a page address for live routes that never declared configurability, and the documented reset edge — a `settings.replace` cannot re-supply a stored *literal* secret in the replaced subtree, which the reference-based default makes unreachable.

+# Agent Note：web 配置平面
+
+Status: implemented

+[English](2026-07-30-web-config-plane.md) | 中文
+
+> 范围：[请求级 LLM 配置 note](2026-07-29-request-level-llm-config-credentials.md) 中延后的 wire 面与 web UI——带推送式失效的 `settings.*`/`credentials.*`/`llm.*` RPC 领域、分层且脱敏的 `describe()`、llm 可配置提供方目录与拓扑事件、独立的 `dsh-client-schema-form` 渲染器，以及 Models 设置页。`deepseek` → `deepseek-official` 提供方路由重命名作为解锁前提的破坏性变更一并搭车合入。
+
+## 问题
+
+PR1 让 LLM（大语言模型）适配器配置在 seam 层面免重启，但唯一的写入方还是直接编辑 `settings.yaml` 的文本编辑器：web 客户端没有触达设置、凭据或提供方拓扑的任何 wire 通道，「存入密钥、再次发起提示」于是仍意味着离开产品本身。挡住配置页的缺口不是一个，而是三个：`describe()` 只返回合并后的生效值（表单分不清用户覆盖与组合默认值，而且照原样序列化会把 `role('secret')` 的值发到每一个浏览器）；没有任何东西枚举适配器*可以*运行的提供方（裸挂载的 `llm-pi-ai` 在配置之前完全不可见）；两个适配器又都想要 `deepseek` 这个路由键，目录因此无法无歧义地把路由归到拥有它的 namespace 名下。为每个提供方手工维护一份表单被直接否决——schema 已经以 schemastery `Config` 值的形式存在，第二份字段真源注定漂移。
+
+## 决策
+
+**wire 领域挂上编译期 RPC 映射，拒绝落为错误码，失效落为帧。**`settings.describe/update/replace`、`credentials.describe/set/unset`、`llm.providers` 与 `llm.models`（认领预留的 `host.listModels` 面）一同加入 `RpcMethodMap`，七处由编译器锁定的接线位点因此让契约、schema、处理器与客户端保持步调一致。seam 侧的拒绝折叠为 `settings-rejected {ns}`/`credential-rejected {ref}` 业务错误（HTTP 仍只是载体），三个 `HostFrame`——`host/settings-changed {ns}`、`host/credentials-changed {ref}`、`host/models-changed`——沿用 `host/commands-changed` 的形状，因此每个客户端都无需轮询即可收敛。写入与 `pickDirectory`/`openPath` 一起进入连接守卫的特权集合：回环 + 同源，否则 403，因为暴露在局域网上的 dsh web 绝不能接受来自其他源的配置修改。
+
+**`describe()` 增加分层与结构化 secret 脱敏。**`SettingsDescriptor` 在生效值之外携带 `base`/`user`，表单据此按「字段是否出现在用户层」来标记「已覆盖」，而非按值是否不等（与 base *相等*的覆盖仍然是覆盖）。`describe({ redactSecrets: true })`——在每个 wire 面都强制启用——经由对 schema 的纯结构遍历（object/dict/array 容器；secret 角色子树整体是一个不透明叶节点）从全部三层剥除 `role('secret')` 子树，并把剥除的槽位枚举为 `{path, set}`，页面因此不必收到任何值就能渲染只写输入框。
+
+**llm seam 声明可配置性并公布拓扑。**`registerConfigurableProviders()` 是一个全有或全无、以 fiber 为作用域的目录，条目为 `{provider, displayName, settingsNs, settingsPath}`——这正是配置页要为一条可能尚不存在的路由打开正确设置子树时所需要的寻址；`listConfigurableProviders()` 在 wire 处理器里与存活路由合并，未声明的存活路由因此仍报告为激活。零负载的 `'llm/adapters-updated'` 事件从全部四个注册／注销提交点触发，listener 派发带异常隔离（INVARIANT 重抛），沿用 settings/commands 的先例。`llm-deepseek` 的路由重命名为 `deepseek-official`，因为 pi-ai catalog 名正言顺地拥有 `deepseek` 这个聚合器条目；依预发布立场，不设别名。
+
+**独立的 schema 驱动表单渲染器。**`dsh-client-schema-form` 把 wire 的 `toJSON()` 信封还原（rehydrate）为活的 schemastery 节点，并按结构分类渲染：object/dict/array 递归展开，全字面量联合成为下拉框（值缺失时显示取自回退层的 `Default: X`），dict 的键联合供给「新增条目」的词汇，凡是无法忠实编辑的一律渲染为只读 JSON——保持可见，绝不丢弃。「是否出现在草稿中」驱动覆盖徽标与逐字段 Reset；`renderField` 钩子让消费方挂载角色专属控件，渲染器自身不必认识任何角色。
+
+**Models 页是一次三领域联接，应用语义与 seam 同形。**每一行是一个已配置的提供方；「新增」词汇是可配置提供方目录中剩余的休眠条目；徽标来自路由存活状态与凭据引用不含值的 `configured` 状态。`credential-ref` 角色挂载凭据控件：引用名进设置，密钥值经 `credentials.set` **只写**存入。不含删除的编辑以一次最小的 `settings.update` 合并 patch 落地（patch 之外已存储的机密得以保留）；字段重置或整行删除则经 `settings.replace` 替换整个用户分节，因为合并语义表达不了删除。
+
+## 曾考虑的替代方案
+
+- **在 wire 上改发 JSON Schema**——schemastery 的 `toJSON()` 信封能往返保留 `role()`/meta，并还原成客户端为草稿校验本就自带的那个校验器；转换成 JSON Schema 丢掉的恰恰是凭据控件与 secret 脱敏所依赖的角色注解。
+- **逐字段脱敏机密并在 `replace` 时回填哨兵值**——PR1 的决策（机密是引用）已经为产品默认形态删掉了「存储字面量」这种情况；结构化脱敏加上只写的凭据通道足以处理残余情形，无需让每个写入方都学会一套哨兵协议。
+- **由 `models` 桥接插件持有提供方配置**——与 PR1 相同的否决理由：按插件划分的 namespace 加上四字段的目录声明已经给了 UI 需要的一切；桥接层的统一字典会把适配器映射那层间接重新引进来。
+- **页面侧轮询而非推送帧**——mux 已经承载 `host/commands-changed`；再加三个帧各自只多一个形状的成本，就让第二个标签页、外部的 `settings.yaml` 编辑和由设置催生的路由都以事件速度收敛。
+
+## 后果
+
+整条闭环以无密钥方式固定在浏览器测试通道（`apps/web/tests/models-settings.e2e.ts`）：休眠的 pi-ai catalog 渲染为「新增」词汇，添加 `anthropic` 会写入 `settings.yaml`、路由随拓扑帧注册为存活，密钥只写存入 harness 家目录的 `.env`，徽标随凭据帧收敛——全程零模型调用，空态与已配置态各有 ARIA golden，另有脚手架式的 `harnessHome`，测试绝不触碰真实的 `~/.dsh`。这次重命名在一次提交中触及 239 个文件（fixture（测试前置数据）、golden、文档、python），未保留兼容别名。延后事项：每行的模型预览（选择器已能列出模型）、为从未声明可配置性的存活路由提供页面地址，以及已记录在案的重置边界情形——`settings.replace` 无法在被替换的子树里重新补上已存储的*字面量*机密，而基于引用的默认形态让这种情况根本无从出现。

+面向 settings 分节的 schema 驱动 React 表单渲染器。wire 侧的 `settings.describe` 携带每个 namespace 的序列化 schemastery schema（`schema.toJSON()` 的 ref 信封）；`SchemaForm` 用 `new Schema(json)` 将其还原（rehydrate），并把每个已声明的字段渲染为可编辑控件——在宿主上校验分节的那份 schema 对象，就是在浏览器里校验并驱动表单的那份对象，因此不存在第二份会漂移的表单定义。
+
+## 契约
+
+`SchemaForm` 是围绕**用户分节草稿**的受控组件：`draft` 是正在编辑的对象（绝不被原地修改；每次编辑都以新的根对象调用 `onChange`），`fallback` 则是用于展示继承值的解析值（schema 默认值 → 组合 base → 用户层）。字段只要出现在草稿中就被标记为**已覆盖**，并显示一个删除该键、回退到继承层的逐字段 Reset——判定采用存在性语义而非值比较，与 settings seam 的分层方式严格对应。
+
+控件按 schema 节点分派：`object` → 带标签的字段组（渲染 JSDoc `description`，`required` 字段加星标）；`string`/`number`/`boolean` → 以继承值为占位符的输入框；字面量 `union` → 下拉框，空选项表示「继承」；`array` → 按位置排列、可增删的行（数组在写入时整体替换）；`dict` → 按键排列的行，其中联合类型的 `sKey` 成为「新增」下拉框的词汇。`role('secret')` 渲染为**只写**的密码输入框：已存储的值永远不会送达（wire 会剥除它），占位状态由 `secrets` 槽位列表（`{path, set}`）提供。渲染器无法忠实编辑的节点（非字面量联合、转换（transform）节点）渲染为带提示的只读 JSON 视图，而不是直接消失——schema 字段绝不会被静默丢弃。
+
+`renderField(context)` 是感知角色的覆盖钩子：返回一个节点，即可替换单个叶子字段的默认控件。Models 设置页用它挂载与 `credentials.*` 通信的凭据引用控件（`role('credential-ref')`）——该包（package）自身始终不接触 wire，也没有副作用。
+
+`validateDraft(schema, draft)` 运行还原出的校验器并返回其失败消息，页面因此可以先校验再写入；路径辅助函数（`getPath`/`hasPath`/`setPath`/`deletePath`）对外暴露的不可变草稿编辑，与控件内部使用的是同一套。
+
+## Model Experience
+
+无。该包渲染的是浏览器配置表单；这里没有任何内容进入模型请求。
+
+#### KV Cache effect
+

+
+## Known Limitations and Deferred Work
+
+- **校验是表单级的，而非逐字段**——`validateDraft` 报告 schemastery 的第一条失败消息（其中会点名 `$.path`）；逐字段的内联报错展示延后到出现需要它的第二个消费方再做。
+- **字符串内置为英文**——`labels` prop 可以覆盖每一条用户可见字符串，但包内没有接入语言环境词典的接线；本地化归嵌入它的页面所有。
+- **非字面量联合与转换节点只读渲染**——忠实编辑这些形状需要逐形状的控件；目前它们回退为带提示的 JSON 视图。
+- **数组编辑整体替换**——settings seam 同样不存在元素级合并；表单如实呈现该契约，而不是把它藏起来。

-Models settings section plugin: registers the `models` nav entry into `settings.section` with an intentionally empty content column — model management lands in a later phase.
+Models settings section plugin: the provider configuration page. It joins three wire domains into one surface — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
+
+Rows are the *configured* providers (their profile resolves in the owning namespace); the add select's vocabulary is every dormant directory entry, so a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor renders the provider's profile subtree through [`@deepseek-ai/dsh-client-schema-form`](../schema-form); the `credential-ref` role mounts the credential control, which shows the reference's live state and stores key values **write-only** through `credentials.set` — no value ever renders back. A row is deletable only when the user layer alone carries it (removal restores the composition base).
+
+Apply semantics mirror the settings seam: an edit without removals lands as a minimal `settings.update` merge patch (stored secrets outside the patch survive), while a field reset or row deletion lands through `settings.replace` of the whole user section so removals actually take effect. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.
 
 ## Model Experience

-模型设置分区插件：注册 `models` 导航项，使其进入 `settings.section`；内容栏有意留空，模型管理将在后续阶段实现。
+模型设置分区插件：提供方配置页。它把三个协议领域汇聚为一个界面——`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）——并渲染提供方行，一次只展开一张编辑卡片。
+
+行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；新增选择框的词汇是全部休眠目录条目，因此裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器经 [`@deepseek-ai/dsh-client-schema-form`](../schema-form) 渲染该提供方的 profile 子树；`credential-ref` 角色会挂载凭据控件，它展示该引用的实时状态，并经 `credentials.set` 以**只写**方式存入密钥值——任何值都绝不回显。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。
+
+「应用」语义与 settings seam 呈镜像：不含删除的编辑以最小的 `settings.update` 合并 patch 落地（patch 之外已存储的 secret 得以保留），字段重置或整行删除则经对整个用户分节的 `settings.replace` 落地，使删除真正生效。页面加载完成后会在推送的失效事件（`settings/changed`、`credentials/changed`、`models/changed` 与 `connection/reset`）上重拉，因此外部的 `settings.yaml` 编辑、第二个标签页或 settings 新生的路由都无需轮询即可收敛。

Your task is to translate the given source document from English to Chinese, producing natural, professional technical prose.\n\n## Quality Requirements\n\n### Structure and Format Preservation\n- Output a complete translated document that maintains exactly the same structure as the source: heading hierarchy, list shape, table columns, link targets, and code blocks.\n- Fenced code blocks must be byte-identical to the source, including ALL comments inside them. Do NOT translate comments inside code blocks. This is a hard rule with no exceptions.\n- Inline code spans (commands, flags, paths, API names, version numbers) must be kept verbatim. Never translate or reformat them.\n- Every relative link must point to the same target as in the source. Link text is translated; link targets are not.\n- Language switcher line: when translating into Chinese, write `[English](source-filename.md) | 中文`. When translating into English, write `English | [中文](source-filename.zh.md)`. Do NOT copy the switcher line from the source file unchanged — you must flip the link direction.\n- After a closing bold marker `**`, insert a space before the next character when that character is a Latin letter, digit, or CJK ideograph. Never insert a space before any punctuation (full-width or half-width).\n\n### Tone and Style\n- The translation must read as if originally written in the target language by a native speaker. If an expression sounds like a word-for-word rendering from the source language, rephrase it.\n- Write in a professional, formal tone appropriate for developer documentation. Never use colloquial or casual expressions.\n- Use polite imperative forms where the text instructs the reader to do something.\n- Keep the author's register: concise stays concise, detailed stays detailed.\n\n### Sentence Structure\n- Break long sentences with commas or semicolons. Avoid run-on sentences.\n- Prefer active voice. Convert passive constructions to active if it reads more naturally.\n- Translate meaning, not words. Restructure sentences where the target language grammar requires it.\n- Do not invent words or expressions that do not exist in natural technical writing of the target language.\n\n### Word Choice\n- Prefer precise, formal vocabulary over casual or colloquial alternatives.\n- When multiple synonyms exist, choose the one most commonly used in professional technical documentation of the target language.\n- Avoid slang, internal jargon, or overly literal translations that would not be recognized by the general developer audience.\n- Do not use the same word to translate two different source-language terms that carry distinct meanings.\n- Avoid repeating the same verb in close proximity; vary word choice for readability.\n\n#### When translating into Chinese\n- When a number modifies a noun, always include a Chinese classifier or measure word (量词). For example: \"three-package seam\" → \"由三个包构成的 seam\", not \"三包 seam\".\n\n### Punctuation\n\n#### When translating into Chinese\n- Use full-width Chinese punctuation in prose: `，。：；？！（）「」`.\n- Strongly prefer replacing all em-dashes (——) with colons, periods, commas, or parentheses. Keep an em-dash only if no other punctuation works at all.\n- Use enumeration commas (、) between parallel items, not regular commas.\n- List item endings: use semicolons or no punctuation. Do not end list items with commas.\n- Put one half-width space between Chinese text and Latin words/numbers.\n- For RFC 2119 keywords (MUST, MUST NOT, SHOULD, MAY), translate to the corresponding Chinese term (必须、禁止、应当、可以) and keep the SOURCE emphasis marker: plain source stays plain (必须), italic source stays italic (*必须*), and bold source stays bold (**必须**).\n\n#### When translating into English\n(To be added.)\n\n## Terminology\n\nA terminology table is provided below. Follow it strictly:\n- Render every listed term exactly as specified.\n- When the target language is Chinese, use the \"中文\" column. On first occurrence, write the \"首次出现\" value with its parenthetical gloss; on subsequent occurrences, write only the part before the parentheses.\n- When the target language is English, use the \"English\" column without a Chinese gloss; do not copy the \"中文\" or \"首次出现\" value into English prose.\n- If a term has already been glossed as part of a compound term, do not gloss it again when it appears alone later.\n- NEVER use translations listed in the \"不要译作\" column.\n- For technical terms not in the table, follow the target language: for a Chinese target, use an established Chinese rendering from a major Chinese-language OSS or vendor source, or keep the source term and flag it as pending when no such precedent exists; for an English target, use the established English technical term, or preserve an ambiguous source term with a short English gloss and flag it as pending.

If Markdown inside any section body contains a line consisting only of `<translation>`, `</translation>`, `<review>`, `</review>`, `<final>`, or `</final>`, prefix that line with `\\`. If the original line already has one or more backslashes immediately before the tag, add one more. The parser removes exactly one framing escape; tags mentioned inline need no escaping.\n\n```xml\n<translation>\n(Complete translation of the source document)\n</translation>\n\n<review>\n(Self-review notes, one correction per line with category tag, e.g.)\n- [Tone] \"旁挂记录\" → \"伴随记录\"（生造词）\n- [Sentence] 第 3 段补充逗号断句\n- [Punctuation] 两处破折号替换为冒号\n- 无修正\n</review>\n\n<final>\n(Final translation after corrections)\n</final>\n```\n\n## Self-Review Instructions\n\nAfter writing `<translation>`, re-read it in the target language only, without looking at the source. Check by category:\n\n**Structure**\n- Is the heading hierarchy, list shape, and code block content identical to the source?\n- Are ALL comments inside code blocks left untranslated (byte-identical to source)?\n- Is the language switcher line correctly flipped (not copied from source)?\n- Are link targets preserved, and are spaces after bold markers present only before Latin letters, digits, or CJK ideographs?\n- Are wrapper-tag lines inside section bodies escaped with one additional backslash?\n\n**Tone & Style**\n- Does every sentence read as if originally written by a native speaker?\n- Is there any colloquial, casual, or overly informal phrasing?\n\n**Sentence Structure**\n- Are there run-on sentences that need breaking?\n- Are there stiff passive constructions that should be converted to active voice?\n\n**Word Choice**\n- Are there overly literal translations that sound unnatural?\n- Is the same target-language word used to translate two distinct source concepts?\n- Is any slang or internal jargon present?\n\n**Terminology**\n- For a Chinese target, are first-occurrence glosses correctly applied (not missing, not repeated)? For an English target, are Chinese glosses absent?\n- Are any \"不要译作\" forbidden translations present?\n- For unlisted terms, does a Chinese target use established Chinese precedent or retain the source term as pending, and does an English target use established English terminology or preserve only an ambiguous source term with a short English gloss?\n\n**Punctuation** (when target is Chinese)\n- Are there em-dashes that should be replaced with colons, periods, or commas?\n- Are list items ending with commas instead of semicolons?\n- Do RFC 2119 keywords preserve the source emphasis exactly?\n\nRecord corrections in `<review>` with category tags. Then output the corrected version in `<final>`. If no corrections are needed, write \"无修正\" in `<review>` and copy the translation unchanged into `<final>`.\n\n## Examples\n\nBelow are representative examples of common problems and their corrections. Follow the \"Good\" versions.\n\n### Colloquial verb → Professional verb\n- Source: `The repo pins pnpm@11.7.0 in package.json`\n- Bad: `仓库在 package.json 中钉住 pnpm@11.7.0`\n- Good: `该仓库在 package.json 中固定使用 pnpm@11.7.0`\n\n### Run-on sentence → Natural phrasing with pause\n- Source: `Read docs/architecture.md before changing anything under packages/.`\n- Bad: `改动 packages/ 下的任何东西之前先读 docs/architecture.md。`\n- Good: `在修改 packages/ 目录下的任何内容之前，请先阅读 docs/architecture.md。`\n\n### Stiff passive voice → Active and natural\n- Source: `a green gate means the pair was confirmed consistent at these exact contents, not that the confirmation was sound.`\n- Bad: `门禁绿意味着这对文档曾在当前内容上被确认一致，不意味着这次确认本身是对的。`\n- Good: `门禁通过意味着这组文档在当前内容上的一致性得到了确认，不代表确认本身正确可靠。`\n\n### Invented word → Natural expression\n- Source: `A sidecar record of both blob hashes makes consistency checkable`\n- Bad: `旁挂记录两侧 blob hash，使一致性可检查`\n- Good: `伴随记录保存两侧 blob hash，使一致性可检查`\n\n### Em-dash → Colon/period\n- Source: `FIXME — an issue that should block a new release. A release should not ship with an open FIXME unless reviewers explicitly agree the change can be merged anyway.`\n- Bad: `FIXME——应当阻塞新版本发布的问题。除非评审者明确同意可以照常合入，发布不应带着未解决的 FIXME 出门。`\n- Good: `FIXME：应当阻塞新版本发布的问题。除非评审者明确同意该更改可以合并，否则发布版本不应包含未解决的 FIXME。`\n\n### Overly literal → Meaningful rendering\n- Source: `awkward phrasing is easier to hear without the source anchoring you`\n- Bad: `没有源文锚着，别扭的表述更容易被听出来`\n- Good: `不对照原文时，更容易察觉别扭的表达`\n\n### Terminology — do not translate what should be kept in English\n- Source: `typed service seams, and explicit extension points`\n- Bad: `类型化的服务 seam（扩展点）与显式扩展点`\n- Good: `类型化的服务 seam 与显式扩展点`\n\n### Slang/jargon → Professional phrasing\n- Source: `The committed agent workflow lives in .agents/skills/dsh-translate-docs`\n- Bad: `进仓的 agent 工作流见 .agents/skills/dsh-translate-docs`\n- Good: `仓库内置的 agent 工作流见 .agents/skills/dsh-translate-docs`\n\n### \"For humans\" — translate the intent, not the word\n- Source: `For humans, start with the development guide`\n- Bad: `对于人工读者，请先从开发指南开始`（\"人工读者\"生硬）\n- Good: `面向开发者：请先阅读开发指南`（\"开发者\"自然，且中文里冒号在此处更自然）\n\n### Code block comments — NEVER translate\n- Source code block contains: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)`\n- Bad: `# 全屏 TUI coding agent（需要 DEEPSEEK_API_KEY）`\n- Good: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)` (keep exactly as-is, byte-for-byte)\n\n### Language switcher — flip direction\n- Source file (English) has: `English | [中文](README.zh.md)`\n- Bad (copying source unchanged): `English | [中文](README.zh.md)`\n- Good (flipped for Chinese file): `[English](README.md) | 中文`\n\n---\n\nNow translate the following document:"
+        "content": "# Translation Prompt\n\nYou are a senior technical translator specializing in LLM and agent development documentation. Your task is to translate the given source document from English to Chinese, producing natural, professional technical prose.\n\n## Quality Requirements\n\n### Structure and Format Preservation\n- Output a complete translated document that maintains exactly the same structure as the source: heading hierarchy, list shape, table columns, link targets, and code blocks.\n- Fenced code blocks must be byte-identical to the source, including ALL comments inside them. Do NOT translate comments inside code blocks. This is a hard rule with no exceptions.\n- Inline code spans (commands, flags, paths, API names, version numbers) must be kept verbatim. Never translate or reformat them.\n- Every relative link must point to the same target as in the source. Link text is translated; link targets are not.\n- Language switcher line: when translating into Chinese, write `[English](source-filename.md) | 中文`. When translating into English, write `English | [中文](source-filename.zh.md)`. Do NOT copy the switcher line from the source file unchanged — you must flip the link direction.\n- After a closing bold marker `**`, insert a space before the next character when that character is a Latin letter, digit, or CJK ideograph. Never insert a space before any punctuation (full-width or half-width).\n\n### Tone and Style\n- The translation must read as if originally written in the target language by a native speaker. If an expression sounds like a word-for-word rendering from the source language, rephrase it.\n- Write in a professional, formal tone appropriate for developer documentation. Never use colloquial or casual expressions.\n- Use polite imperative forms where the text instructs the reader to do something.\n- Keep the author's register: concise stays concise, detailed stays detailed.\n\n### Sentence Structure\n- Break long sentences with commas or semicolons. Avoid run-on sentences.\n- Prefer active voice. Convert passive constructions to active if it reads more naturally.\n- Translate meaning, not words. Restructure sentences where the target language grammar requires it.\n- Do not invent words or expressions that do not exist in natural technical writing of the target language.\n\n### Word Choice\n- Prefer precise, formal vocabulary over casual or colloquial alternatives.\n- When multiple synonyms exist, choose the one most commonly used in professional technical documentation of the target language.\n- Avoid slang, internal jargon, or overly literal translations that would not be recognized by the general developer audience.\n- Do not use the same word to translate two different source-language terms that carry distinct meanings.\n- Avoid repeating the same verb in close proximity; vary word choice for readability.\n\n#### When translating into Chinese\n- When a number modifies a noun, always include a Chinese classifier or measure word (量词). For example: \"three-package seam\" → \"由三个包构成的 seam\", not \"三包 seam\".\n\n### Punctuation\n\n#### When translating into Chinese\n- Use full-width Chinese punctuation in prose: `，。：；？！（）「」`.\n- Strongly prefer replacing all em-dashes (——) with colons, periods, commas, or parentheses. Keep an em-dash only if no other punctuation works at all.\n- Use enumeration commas (、) between parallel items, not regular commas.\n- List item endings: use semicolons or no punctuation. Do not end list items with commas.\n- Put one half-width space between Chinese text and Latin words/numbers.\n- For RFC 2119 keywords (MUST, MUST NOT, SHOULD, MAY), translate to the corresponding Chinese term (必须、禁止、应当、可以) and keep the SOURCE emphasis marker: plain source stays plain (必须), italic source stays italic (*必须*), and bold source stays bold (**必须**).\n\n#### When translating into English\n(To be added.)\n\n## Terminology\n\nA terminology table is provided below. Follow it strictly:\n- Render every listed term exactly as specified.\n- When the target language is Chinese, use the \"中文\" column. On first occurrence, write the \"首次出现\" value with its parenthetical gloss; on subsequent occurrences, write only the part before the parentheses.\n- When the target language is English, use the \"English\" column without a Chinese gloss; do not copy the \"中文\" or \"首次出现\" value into English prose.\n- If a term has already been glossed as part of a compound term, do not gloss it again when it appears alone later.\n- NEVER use translations listed in the \"不要译作\" column.\n- For technical terms not in the table, follow the target language: for a Chinese target, use an established Chinese rendering from a major Chinese-language OSS or vendor source, or keep the source term and flag it as pending when no such precedent exists; for an English target, use the established English technical term, or preserve an ambiguous source term with a short English gloss and flag it as pending. Do not invent a translation. This rule applies to terminology only; for general prose, freely restructure and paraphrase for natural expression.\n\n# Terminology\n\n本表约定本仓库的中英术语统一译法。\n\n**通用规则：**\n- \"中文\"列为中文译文的正文默认用词。若该列为英文，则中文译文的正文中保留英文不翻译。\n- 首次出现按\"首次出现\"列书写（带括号注释）；后续出现只写括号前的部分（可能为中文，也可能为英文），不出现括号内的注释。\n- \"不要译作\"列为严格禁止的译法。\n- 如果某术语已经作为另一个术语的组成部分被括注过（如 `agent loop（智能体循环）` 中已包含 `agent` 的括注），则该术语后续单独出现时无需再次括注。\n\n## 缩写类（中英文文本中均使用缩写）\n\n| English | 中文 | 首次出现 | 不要译作 | 备注 |\n|---|---|---|---|---|\n| ACP | ACP | ACP（Agent Client Protocol） | | |\n| AI | AI | AI（人工智能） | | |\n| API | API |

tags are framing. If Markdown inside any section body contains a line consisting only of `<translation>`, `</translation>`, `<review>`, `</review>`, `<final>`, or `</final>`, prefix that line with `\\`. If the original line already has one or more backslashes immediately before the tag, add one more. The parser removes exactly one framing escape; tags mentioned inline need no escaping.\n\n```xml\n<translation>\n(Complete translation of the source document)\n</translation>\n\n<review>\n(Self-review notes, one correction per line with category tag, e.g.)\n- [Tone] \"旁挂记录\" → \"伴随记录\"（生造词）\n- [Sentence] 第 3 段补充逗号断句\n- [Punctuation] 两处破折号替换为冒号\n- 无修正\n</review>\n\n<final>\n(Final translation after corrections)\n</final>\n```\n\n## Self-Review Instructions\n\nAfter writing `<translation>`, re-read it in the target language only, without looking at the source. Check by category:\n\n**Structure**\n- Is the heading hierarchy, list shape, and code block content identical to the source?\n- Are ALL comments inside code blocks left untranslated (byte-identical to source)?\n- Is the language switcher line correctly flipped (not copied from source)?\n- Are link targets preserved, and are spaces after bold markers present only before Latin letters, digits, or CJK ideographs?\n- Are wrapper-tag lines inside section bodies escaped with one additional backslash?\n\n**Tone & Style**\n- Does every sentence read as if originally written by a native speaker?\n- Is there any colloquial, casual, or overly informal phrasing?\n\n**Sentence Structure**\n- Are there run-on sentences that need breaking?\n- Are there stiff passive constructions that should be converted to active voice?\n\n**Word Choice**\n- Are there overly literal translations that sound unnatural?\n- Is the same target-language word used to translate two distinct source concepts?\n- Is any slang or internal jargon present?\n\n**Terminology**\n- For a Chinese target, are first-occurrence glosses correctly applied (not missing, not repeated)? For an English target, are Chinese glosses absent?\n- Are any \"不要译作\" forbidden translations present?\n- For unlisted terms, does a Chinese target use established Chinese precedent or retain the source term as pending, and does an English target use established English terminology or preserve only an ambiguous source term with a short English gloss?\n\n**Punctuation** (when target is Chinese)\n- Are there em-dashes that should be replaced with colons, periods, or commas?\n- Are list items ending with commas instead of semicolons?\n- Do RFC 2119 keywords preserve the source emphasis exactly?\n\nRecord corrections in `<review>` with category tags. Then output the corrected version in `<final>`. If no corrections are needed, write \"无修正\" in `<review>` and copy the translation unchanged into `<final>`.\n\n## Examples\n\nBelow are representative examples of common problems and their corrections. Follow the \"Good\" versions.\n\n### Colloquial verb → Professional verb\n- Source: `The repo pins pnpm@11.7.0 in package.json`\n- Bad: `仓库在 package.json 中钉住 pnpm@11.7.0`\n- Good: `该仓库在 package.json 中固定使用 pnpm@11.7.0`\n\n### Run-on sentence → Natural phrasing with pause\n- Source: `Read docs/architecture.md before changing anything under packages/.`\n- Bad: `改动 packages/ 下的任何东西之前先读 docs/architecture.md。`\n- Good: `在修改 packages/ 目录下的任何内容之前，请先阅读 docs/architecture.md。`\n\n### Stiff passive voice → Active and natural\n- Source: `a green gate means the pair was confirmed consistent at these exact contents, not that the confirmation was sound.`\n- Bad: `门禁绿意味着这对文档曾在当前内容上被确认一致，不意味着这次确认本身是对的。`\n- Good: `门禁通过意味着这组文档在当前内容上的一致性得到了确认，不代表确认本身正确可靠。`\n\n### Invented word → Natural expression\n- Source: `A sidecar record of both blob hashes makes consistency checkable`\n- Bad: `旁挂记录两侧 blob hash，使一致性可检查`\n- Good: `伴随记录保存两侧 blob hash，使一致性可检查`\n\n### Em-dash → Colon/period\n- Source: `FIXME — an issue that should block a new release. A release should not ship with an open FIXME unless reviewers explicitly agree the change can be merged anyway.`\n- Bad: `FIXME——应当阻塞新版本发布的问题。除非评审者明确同意可以照常合入，发布不应带着未解决的 FIXME 出门。`\n- Good: `FIXME：应当阻塞新版本发布的问题。除非评审者明确同意该更改可以合并，否则发布版本不应包含未解决的 FIXME。`\n\n### Overly literal → Meaningful rendering\n- Source: `awkward phrasing is easier to hear without the source anchoring you`\n- Bad: `没有源文锚着，别扭的表述更容易被听出来`\n- Good: `不对照原文时，更容易察觉别扭的表达`\n\n### Terminology — do not translate what should be kept in English\n- Source: `typed service seams, and explicit extension points`\n- Bad: `类型化的服务 seam（扩展点）与显式扩展点`\n- Good: `类型化的服务 seam 与显式扩展点`\n\n### Slang/jargon → Professional phrasing\n- Source: `The committed agent workflow lives in .agents/skills/dsh-translate-docs`\n- Bad: `进仓的 agent 工作流见 .agents/skills/dsh-translate-docs`\n- Good: `仓库内置的 agent 工作流见 .agents/skills/dsh-translate-docs`\n\n### \"For humans\" — translate the intent, not the word\n- Source: `For humans, start with the development guide`\n- Bad: `对于人工读者，请先从开发指南开始`（\"人工读者\"生硬）\n- Good: `面向开发者：请先阅读开发指南`（\"开发者\"自然，且中文里冒号在此处更自然）\n\n### Code block comments — NEVER translate\n- Source code block contains: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)`\n- Bad: `# 全屏 TUI coding agent（需要 DEEPSEEK_API_KEY）`\n- Good: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)` (keep exactly as-is, byte-for-byte)\n\n### Language switcher — flip direction\n- Source file (English) has: `English | [中文](README.zh.md)`\n- Bad (copying source unchanged): `English | [中文](README.zh.md)`\n- Good (flipped for Chinese file): `[English](README.md) | 中文`\n\n---\n\nNow translate the following document:"

Subject: [PATCH 024/102] feat(ui-models)!: single-key hand-written provider
 editors with derived credential references

The Models page drops the generic schema renderer and the visible
environment-variable field: each editor is a curated per-family card whose
primary input is one write-only API key stored under a derived
<ROUTE>_API_KEY reference (recorded as apiKeyEnv in the pi-ai profile), an
unkeyed whole-section provider opens as its setup card, and the collapsed
customized-settings fold carries baseURL/reasoningEffort (deepseek) or
reasoning (pi-ai). dsh-client-schema-form reduces to the schema/draft model
layer (no React).

-Schema-driven React form renderer for settings sections. The wire's `settings.describe` carries each namespace's serialized schemastery schema (`schema.toJSON()` ref envelope); `SchemaForm` rehydrates it with `new Schema(json)` and renders every declared field as an editable control — the same schema object that validates a section on the host validates and drives the form in the browser, so there is no second form definition to drift.
+Schema/draft model layer for settings editors. The wire's `settings.describe` carries each namespace's serialized schemastery schema (`schema.toJSON()` ref envelope); `rehydrateSchema` turns it back into a live validator with `new Schema(json)` — the same schema object that validates a section on the host validates drafts in the browser, so client-side validation never drifts from the seam's. Editors render their own controls (the Models page hand-writes its card around the fields it probes here); this package owns no React and no rendering.
 
 ## Contract
 
-`SchemaForm` is a controlled component over a **draft user section**: `draft` is the object being edited (never mutated; every edit calls `onChange` with a new root), and `fallback` is the resolved value (schema defaults → composition base → user layer) used for inherited display. A field's presence in the draft marks it **overridden** and shows a per-field Reset that deletes the key, falling back to the inherited layer — presence semantics, not value comparison, exactly mirroring the settings seam's layering.
-
-Controls by schema node: `object` → labeled field groups (JSDoc `description` rendered, `required` starred), `string`/`number`/`boolean` → inputs with the inherited value as placeholder, `union` of literals → select whose empty option means "inherit", `array` → positional rows with add/remove (arrays replace wholesale on write), `dict` → keyed rows where a union-typed `sKey` becomes the add-select's vocabulary. `role('secret')` renders a **write-only** password input: the stored value never arrives (the wire strips it), and the `secrets` slot list (`{path, set}`) supplies the placeholder state. A node the renderer cannot faithfully edit (non-literal unions, transforms) renders a read-only JSON view with a notice instead of disappearing — a schema field is never silently dropped.
-
-`renderField(context)` is the role-aware override hook: return a node to replace the default control for one leaf. The Models settings page uses it to mount the credential-reference control (`role('credential-ref')`) that talks to `credentials.*` — this package stays wire-free and side-effect-free.
-
-`validateDraft(schema, draft)` runs the rehydrated validator and returns its failure message, letting pages validate before writing; the path helpers (`getPath`/`hasPath`/`setPath`/`deletePath`) expose the same immutable draft editing the controls use.
+The unit of editing is a **draft user section**: a plain object edited immutably (`setPath` materializes intermediates, `deletePath` is the per-field reset — dropping the key falls the resolved value back to the composition base and schema defaults). A field's presence in the draft marks it **overridden** (`hasPath`) — presence semantics, not value comparison, exactly mirroring the settings seam's layering. `nodeAtPath` resolves the schema node addressed by a configurable-provider directory `settingsPath` (object properties by name, dict entries through `inner`), so an editor can probe which fields a provider's profile carries (and their `meta.role`) before deciding what to render; an unresolvable path returns `undefined` so the caller degrades loudly instead of rendering a wrong subtree. `validateDraft(schema, draft)` runs the rehydrated validator and returns its failure message, letting pages reject an invalid draft before writing.

-- **Validation is form-level, not per-field** — `validateDraft` reports schemastery's first failure message (which names the `$.path`); inline per-field error placement is deferred until a second consumer needs it.
-- **Strings are built-in English** — the `labels` prop overrides every user-visible string, but there is no locale-dictionary wiring inside this package; the embedding page owns localization.
-- **Non-literal unions and transforms render read-only** — faithful editing of those shapes needs per-shape controls; today they fall back to the JSON view with a notice.
-- **Array editing replaces wholesale** — element-level merge does not exist at the settings seam either; the form mirrors that contract rather than hiding it.
+- **Validation is draft-level, not per-field** — `validateDraft` reports schemastery's first failure message (which names the `$.path`); per-field error mapping is deferred until a consumer needs it.

-面向 settings 分节的 schema 驱动 React 表单渲染器。wire 侧的 `settings.describe` 携带每个 namespace 的序列化 schemastery schema（`schema.toJSON()` 的 ref 信封）；`SchemaForm` 用 `new Schema(json)` 将其还原（rehydrate），并把每个已声明的字段渲染为可编辑控件——在宿主上校验分节的那份 schema 对象，就是在浏览器里校验并驱动表单的那份对象，因此不存在第二份会漂移的表单定义。
+面向 settings 编辑器的 schema／草稿模型层。wire 侧的 `settings.describe` 携带每个 namespace 的序列化 schemastery schema（`schema.toJSON()` 的 ref 信封）；`rehydrateSchema` 用 `new Schema(json)` 将其还原（rehydrate）为活的校验器——在宿主上校验分节的那份 schema 对象，就是在浏览器里校验草稿的那份对象，因此客户端校验绝不会偏离 seam 侧的校验。编辑器各自渲染自己的控件（Models 页围绕它在此探测到的字段手写自己的卡片）；该包（package）不含任何 React，也不做任何渲染。
 
 ## 契约
 
-`SchemaForm` 是围绕**用户分节草稿**的受控组件：`draft` 是正在编辑的对象（绝不被原地修改；每次编辑都以新的根对象调用 `onChange`），`fallback` 则是用于展示继承值的解析值（schema 默认值 → 组合 base → 用户层）。字段只要出现在草稿中就被标记为**已覆盖**，并显示一个删除该键、回退到继承层的逐字段 Reset——判定采用存在性语义而非值比较，与 settings seam 的分层方式严格对应。
-
-控件按 schema 节点分派：`object` → 带标签的字段组（渲染 JSDoc `description`，`required` 字段加星标）；`string`/`number`/`boolean` → 以继承值为占位符的输入框；字面量 `union` → 下拉框，空选项表示「继承」；`array` → 按位置排列、可增删的行（数组在写入时整体替换）；`dict` → 按键排列的行，其中联合类型的 `sKey` 成为「新增」下拉框的词汇。`role('secret')` 渲染为**只写**的密码输入框：已存储的值永远不会送达（wire 会剥除它），占位状态由 `secrets` 槽位列表（`{path, set}`）提供。渲染器无法忠实编辑的节点（非字面量联合、转换（transform）节点）渲染为带提示的只读 JSON 视图，而不是直接消失——schema 字段绝不会被静默丢弃。
-
-`renderField(context)` 是感知角色的覆盖钩子：返回一个节点，即可替换单个叶子字段的默认控件。Models 设置页用它挂载与 `credentials.*` 通信的凭据引用控件（`role('credential-ref')`）——该包（package）自身始终不接触 wire，也没有副作用。
-
-`validateDraft(schema, draft)` 运行还原出的校验器并返回其失败消息，页面因此可以先校验再写入；路径辅助函数（`getPath`/`hasPath`/`setPath`/`deletePath`）对外暴露的不可变草稿编辑，与控件内部使用的是同一套。
+编辑的单元是**用户分节草稿**：一个以不可变方式编辑的普通对象（`setPath` 会物化中间对象，`deletePath` 即逐字段重置——去掉该键，解析值便回退到组合 base 与 schema 默认值）。字段只要出现在草稿中就被标记为**已覆盖**（`hasPath`）——判定采用存在性语义而非值比较，与 settings seam 的分层方式严格对应。`nodeAtPath` 解析可配置提供方目录 `settingsPath` 所寻址的 schema 节点（object 属性按名称解析，dict 条目经由 `inner`），编辑器因此可以在决定渲染什么之前，先探测某提供方的 profile 携带哪些字段（及其 `meta.role`）；无法解析的路径返回 `undefined`，调用方因此会大声降级，而不是渲染出错误的子树。`validateDraft(schema, draft)` 运行还原出的校验器并返回其失败消息，页面因此可以在写入前拒绝无效草稿。

 /**
- * One provider's editor card: the schema-driven form over its profile

- * Apply without removals merges (`settings.update`, preserving stored keys
- * outside the patch); apply after a field reset replaces the user section so
- * the reset actually lands.
+ * One provider's editor card, hand-written per adapter family: the primary
+ * field is a single write-only **API key** input (the page never asks for an
+ * environment-variable name — a typed key stores through `credentials.set`
+ * under the profile's reference, deriving `<ROUTE>_API_KEY` when the profile
+ * has none, and the pi-ai profile records that derivation as `apiKeyEnv`);
+ * the collapsed 自定义设置 area carries the per-family extras (deepseek:
+ * `baseURL` + `reasoningEffort`; pi-ai: `reasoning`). Everything else stays
+ * owned by `settings.yaml` — the folded hint says so. Profile edits land as a
+ * minimal `settings.update` merge patch; clearing a field back to inherited
+ * removes its key, so that apply replaces the user section (safe: the section
+ * stores references, never key values).

 Models settings section plugin: the provider configuration page. It joins three wire domains into one surface — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
 
-Rows are the *configured* providers (their profile resolves in the owning namespace); the add select's vocabulary is every dormant directory entry, so a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor renders the provider's profile subtree through [`@deepseek-ai/dsh-client-schema-form`](../schema-form); the `credential-ref` role mounts the credential control, which shows the reference's live state and stores key values **write-only** through `credentials.set` — no value ever renders back. A row is deletable only when the user layer alone carries it (removal restores the composition base).
+Rows are the *configured* providers (their profile resolves in the owning namespace); a whole-section provider whose key is not configured anywhere (the first-run DeepSeek posture) renders as its open setup card instead of a row, and the add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor is a hand-written card per adapter family: the primary field is a single **API key** input — the page never asks for an environment-variable name; a typed key stores **write-only** through `credentials.set` under the profile's reference, deriving `<ROUTE>_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. The collapsed 自定义设置 fold carries the curated extras — `baseURL` for both families (the deepseek placeholder shows the public endpoint), plus `reasoningEffort` (deepseek) or `reasoning` (pi-ai); every other profile field stays owned by `settings.yaml`. A row is deletable only when the user layer alone carries it (removal restores the composition base).
 
-Apply semantics mirror the settings seam: an edit without removals lands as a minimal `settings.update` merge patch (stored secrets outside the patch survive), while a field reset or row deletion lands through `settings.replace` of the whole user section so removals actually take effect. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.

 ## Model Experience
 
@@ -19,5 +19,7 @@ None; this package neither assembles nor sends a provider request.
 ## Known Limitations and Deferred Work
 
 - **A reset can drop a stored literal secret in the same subtree** — a replace-carried removal cannot re-supply secrets the wire never returned; store keys behind `credentials.*` references (the product default) and the case cannot arise.
+- **Only the API key and the curated fold fields are editable on the card** — the hand-written editor traded schema-generic field coverage for the mockup layout ([Agent Note](../../../.agents/notes/implemented/architecture/2026-07-30-web-config-plane.md)); advanced fields (`models`, retry policy, timeouts…) are edited in `settings.yaml`, which the fold points at. A profile schema without the conventional fields renders the hint alone, and the two curated layouts key on the `llm-deepseek`/`llm-pi-ai` namespaces by name.
+- **Deleting a row leaves its stored key in `.env`** — removal replaces the settings profile but deliberately does not unset the derived credential; re-adding the provider finds the key already configured. An explicit key-removal control is deferred.
 - **No per-provider model listing on the page** — the picker surfaces models; this page shows route state only. A models preview per row is deferred until a consumer needs it.
 - **Undeclared live routes render nowhere** — a route registered without a configurable-provider declaration has no settings address; it stays visible in pickers but not on this page's rows.

 模型设置分区插件：提供方配置页。它把三个协议领域汇聚为一个界面——`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）——并渲染提供方行，一次只展开一张编辑卡片。
 
-行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；新增选择框的词汇是全部休眠目录条目，因此裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器经 [`@deepseek-ai/dsh-client-schema-form`](../schema-form) 渲染该提供方的 profile 子树；`credential-ref` 角色会挂载凭据控件，它展示该引用的实时状态，并经 `credentials.set` 以**只写**方式存入密钥值——任何值都绝不回显。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。
+行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；密钥未在任何地方配置的整分节提供方（DeepSeek 的首次运行姿态）会渲染为其展开的设置卡片而非一行，「新增」流程则是一张承载休眠目录提供方选择框的卡片——裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器是每个适配器家族各一张的手写卡片：主字段是单独一个 **API 密钥**输入框——页面从不询问环境变量名；键入的密钥经 `credentials.set` 以**只写**方式存入 profile 的引用之下，profile 没有引用时便派生 `<ROUTE>_API_KEY`，pi-ai profile 会把这次派生记录为 `apiKeyEnv`，因此 `settings.yaml` 从不携带密钥值。收起的「自定义设置」折叠区承载精选的额外字段（deepseek：`baseURL` + `reasoningEffort`；pi-ai：`reasoning`）；其余每个 profile 字段仍归 `settings.yaml` 所有，折叠区上也会明说。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。
 
-「应用」语义与 settings seam 呈镜像：不含删除的编辑以最小的 `settings.update` 合并 patch 落地（patch 之外已存储的 secret 得以保留），字段重置或整行删除则经对整个用户分节的 `settings.replace` 落地，使删除真正生效。页面加载完成后会在推送的失效事件（`settings/changed`、`credentials/changed`、`models/changed` 与 `connection/reset`）上重拉，因此外部的 `settings.yaml` 编辑、第二个标签页或 settings 新生的路由都无需轮询即可收敛。

 ## 已知限制与暂缓事项
 
 - **重置可能丢弃同一子树中已存储的字面 secret**：经 replace 承载的删除无法重新提供协议从未返回过的 secret；把密钥放在 `credentials.*` 引用背后（产品默认做法），该情形便不会出现。
+- **卡片上可编辑的只有 API 密钥与精选折叠区字段**：手写编辑器用 schema 通用的字段覆盖面换来了设计稿上的布局（[Agent Note（agent 决策记录）](../../../.agents/notes/implemented/architecture/2026-07-30-web-config-plane.md)）；进阶字段（`models`、重试策略、超时……）在 `settings.yaml` 中编辑，折叠区会指向它。不带这些约定字段的 profile schema 只渲染该提示，两套精选布局则以 `llm-deepseek`/`llm-pi-ai` 这两个 namespace 的名字为键。
+- **删除一行会把它已存储的密钥留在 `.env` 里**：删除替换的是 settings profile，却刻意不清除那条派生凭据；重新添加该提供方时会发现密钥已配置。显式的密钥移除控件暂缓。
 - **页面上没有逐提供方的模型列表**：模型由选择器呈现；本页只展示路由状态。逐行的模型预览暂缓，待有消费方需要时再实现。
 - **未声明的存活路由无处渲染**：未附带可配置提供方声明即注册的路由没有 settings 地址；它在各选择器中仍然可见，但不会出现在本页的行里。

+# Agent Note: official DeepSeek first-run credential setup
+
+Status: implemented
+
+English | [中文](2026-07-30-deepseek-onboarding-credential-setup.zh.md)
+
+## Problem
+
+The [web configuration plane](../architecture/2026-07-30-web-config-plane.md) makes provider settings and credentials live-editable, but a first-time user still lands on the empty conversation Hero without an actionable explanation when the shipped `deepseek-official` route has no credential. The Models page can repair that state, yet requiring the user to discover it weakens onboarding. A prompt must not confuse a missing credential with a missing adapter: the browser can store a value for an existing credential reference, but it cannot dynamically mount the `llm-deepseek` Cordis plugin.
+
+## Decision
+
+**One readiness projection owns both Models and onboarding facts.** `ui-models` keeps a single store that joins `llm.providers({})`, redacted `settings.describe({})`, and batched `credentials.describe({refs})`. The onboarding projection selects the `deepseek-official` configurable-provider entry, resolves its `settingsNs` and `settingsPath`, reads the effective `apiKeyEnv`, and evaluates the matching credential descriptor. A configured literal `apiKey` secret sidecar is also ready, so compatibility configuration does not trigger a false prompt; a configured process-environment credential is ready and remains read-only.
+
+**The settings shell contributes navigation state, not provider policy.** `ui-settings` declares a root-scoped `settings.onboarding` list slot and tells registrants whether the current surface is the empty Hero. Its private `openSection(id)` callback opens the settings panel on one registered section. `ui-models` registers the DeepSeek overlay through the same declaration-aware deferred-registration path as its Models section, so plugin load order does not become a contract.
+
+**The prompt is a credential-only write path.** A mounted, active adapter with a resolved, writable, unconfigured reference presents a password input. Submit calls only `credentials.set({ref, value})`, clears the React draft after success, refetches the shared join, and closes only when the new descriptor reports `configured: true`. Business failures and transport rejections keep the dialog open, restore its busy state in `finally`, and redact the submitted value from rendered error text. The prompt never writes `apiKey`, `baseURL`, or a redacted settings section; advanced configuration opens Models instead.
+
+**Unavailable capability states stay honest.** An absent configurable-provider entry suppresses the form because it cannot repair the composition. A present provider whose settings or credential capability cannot be resolved renders an actionable deployment diagnostic. Cancel dismisses the overlay for the current mounted surface and writes no completion fact. Settings, credential, provider-topology, and connection invalidations all refresh the shared join, so an external credential update closes an open prompt without a reload.
+
+## Alternatives considered
+
+**A separate onboarding store and readiness RPC sequence** — rejected because it would create a second client-side interpretation of provider identity, settings paths, secret sidecars, credential references, and invalidation ordering beside the Models page.
+
+**Writing the API key into provider settings** — rejected because a literal secret would enter the settings mutation path and whole-section replacement cannot safely reconstruct redacted values. Credential storage is already the product seam and supplies immediate invalidation.
+
+**Showing the same key form when `llm-deepseek` is absent** — rejected because success would only store an unused environment reference; the browser has no supported operation that mounts the missing Cordis plugin.
+
+## Consequences
+
+The first-run flow now repairs the shipped adapter without restarting: a keyless browser test boots the real Web composition under an isolated harness home, observes the dialog, stores a generated key into that home's `.env`, verifies no key reaches DOM, ARIA, or browser console output, and confirms the running Models page reports configured. Pure readiness and React tests pin literal, file, process-environment, missing-provider, missing-capability, business-error, transport-error, cancellation, and external-invalidation behavior. The flow deliberately inherits the configuration plane's documented base limitations rather than adding local secret storage, redaction, or settings replacement workarounds.

+# Agent Note: DeepSeek 官方首次使用凭据配置
+
+Status: implemented
+
+[English](2026-07-30-deepseek-onboarding-credential-setup.md) | 中文
+
+## 问题
+
+[web 配置平面](../architecture/2026-07-30-web-config-plane.md)让提供方设置与凭据可以实时编辑，但首次使用的用户仍会进入空白对话 Hero；当随产品提供的 `deepseek-official` 路由缺少凭据时，界面没有给出可采取操作的说明。Models 页能修复该状态，但要求用户自行发现这个入口会削弱首次使用引导。界面不得混淆凭据缺失与适配器缺失：浏览器可以为现有凭据引用存入值，但无法动态挂载 `llm-deepseek` Cordis 插件。
+
+## 决策
+
+**Models 与首次使用引导共享同一个就绪状态投影。**`ui-models` 维护一个 store，把 `llm.providers({})`、脱敏后的 `settings.describe({})` 和批量调用的 `credentials.describe({refs})` 联接为同一份状态。首次使用投影选取 `deepseek-official` 可配置提供方条目，解析其 `settingsNs` 与 `settingsPath`，读取生效的 `apiKeyEnv`，并检查对应的凭据描述符。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，也会判定为就绪，兼容配置因此不会误触发浮层；通过进程环境提供的凭据若已配置，同样判定为就绪并保持只读。
+
+**设置外壳只贡献导航状态，不持有提供方策略。**`ui-settings` 声明一个根作用域的 `settings.onboarding` list slot，并告知注册方当前界面是否为空白 Hero。其私有 `openSection(id)` 回调会打开设置面板并切换到一个已注册分区。`ui-models` 沿用 Models 分区所使用、感知 slot 声明的延迟注册路径来注册 DeepSeek 浮层，因此插件加载顺序不会成为契约。
+
+**浮层只通过凭据写入路径提交。**适配器已挂载且处于活跃状态，其引用可解析、可写但尚未配置时，界面会显示密码输入框。提交时只调用 `credentials.set({ref, value})`；成功后清空 React 草稿、重新拉取共享联接，并且仅在新描述符报告 `configured: true` 时关闭浮层。业务失败与传输层拒绝都会让对话框保持打开，在 `finally` 中解除忙碌状态，并从渲染的错误文本中脱敏已提交的值。该浮层绝不写入 `apiKey`、`baseURL` 或经过脱敏的设置分节；高级配置会转到 Models。
+
+**能力不可用时如实呈现。**可配置提供方条目缺失时不显示表单，因为它无法修复当前组合。提供方存在，但设置或凭据能力无法解析时，界面会显示可采取操作的部署诊断。取消只会在当前已挂载界面中关闭浮层，不写入任何完成状态。设置、凭据、提供方拓扑和连接失效事件都会刷新共享联接，因此外部凭据更新无需重新加载页面即可关闭已打开的浮层。
+
+## 曾考虑的替代方案
+
+**为首次使用引导单设 store 与就绪状态 RPC 调用序列**：不予采用，因为这会在 Models 页之外，再建立一套客户端解释，用于判定提供方身份、设置路径、secret 槽位的伴随信息、凭据引用及失效事件顺序。
+
+**把 API key 写入提供方设置**：不予采用，因为字面量 secret 会进入设置变更路径，而整个分节替换无法安全重建脱敏值。凭据存储已经是产品 seam，并能立即发出失效事件。
+
+**`llm-deepseek` 缺失时仍显示同一个密钥表单**：不予采用，因为提交成功也只会存储一个无人使用的环境引用；浏览器没有任何受支持的操作可以挂载缺失的 Cordis 插件。
+
+## 后果
+
+首次使用流程无需重启即可修复随产品提供的适配器：无密钥浏览器测试在隔离的 harness 家目录下启动真实 Web 组合，确认对话框出现，把生成的密钥存入该目录的 `.env`，验证密钥未进入 DOM、ARIA 或浏览器控制台输出，并确认运行中的 Models 页报告已配置。纯就绪状态测试与 React 测试固化了字面量凭据、文件凭据、进程环境凭据、提供方缺失、能力缺失、业务错误、传输错误、取消和外部失效行为。该流程直接继承配置平面已记录的基础限制，不会另加局部的机密存储、脱敏或设置替换变通方案。

-Models settings section plugin: the provider configuration page. It joins three wire domains into one surface — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
+Models settings plugin: the provider configuration page and official-DeepSeek first-run credential overlay. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
 
 Rows are the *configured* providers (their profile resolves in the owning namespace); the add select's vocabulary is every dormant directory entry, so a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor renders the provider's profile subtree through [`@deepseek-ai/dsh-client-schema-form`](../schema-form); the `credential-ref` role mounts the credential control, which shows the reference's live state and stores key values **write-only** through `credentials.set` — no value ever renders back. A row is deletable only when the user layer alone carries it (removal restores the composition base).
 
+The first-run overlay projects `deepseek-official` readiness from that same joined snapshot. A configured literal `apiKey` secret sidecar or configured credential reference suppresses the prompt, including a read-only launch-environment credential. A mounted adapter with a writable missing reference opens the password form and writes only through `credentials.set`; success is accepted only after a fresh describe reports configured. An absent adapter is skipped because a browser form cannot mount Cordis plugins, while a present but unusable settings or credential capability produces a deployment diagnostic and an advanced link opens the Models section.
+
 Apply semantics mirror the settings seam: an edit without removals lands as a minimal `settings.update` merge patch (stored secrets outside the patch survive), while a field reset or row deletion lands through `settings.replace` of the whole user section so removals actually take effect. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.

-模型设置分区插件：提供方配置页。它把三个协议领域汇聚为一个界面——`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）——并渲染提供方行，一次只展开一张编辑卡片。
+模型设置插件：提供方配置页和 DeepSeek 官方首次使用凭据浮层。它把三个协议领域汇聚为一个共享快照：`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）；页面据此渲染提供方行，一次只展开一张编辑卡片。
 
 行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；新增选择框的词汇是全部休眠目录条目，因此裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器经 [`@deepseek-ai/dsh-client-schema-form`](../schema-form) 渲染该提供方的 profile 子树；`credential-ref` 角色会挂载凭据控件，它展示该引用的实时状态，并经 `credentials.set` 以**只写**方式存入密钥值——任何值都绝不回显。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。
 
+首次使用浮层从同一个联接快照得出 `deepseek-official` 的就绪状态。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，浮层就不再显示，其中包括来自启动环境且只读的凭据。适配器已挂载、引用可写但尚未配置时，浮层会打开密码表单，且只经 `credentials.set` 写入；只有重新调用 describe 并确认已配置后，才会接受此次提交。适配器缺失时直接跳过，因为浏览器表单无法挂载 Cordis 插件；提供方存在但设置或凭据能力不可用时，则显示部署诊断，并通过高级设置链接打开 Models 分区。
+
 「应用」语义与 settings seam 呈镜像：不含删除的编辑以最小的 `settings.update` 合并 patch 落地（patch 之外已存储的 secret 得以保留），字段重置或整行删除则经对整个用户分节的 `settings.replace` 落地，使删除真正生效。页面加载完成后会在推送的失效事件（`settings/changed`、`credentials/changed`、`models/changed` 与 `connection/reset`）上重拉，因此外部的 `settings.yaml` 编辑、第二个标签页或 settings 新生的路由都无需轮询即可收敛。

-Settings shell plugin: a pure composition face. It occupies `sidebar.settings` with the trigger chrome and the modal settings panel, and declares the slots registrants fill: `settings.trigger` / `settings.header` / `settings.close` (chrome content) and `settings.section` (one page per feature). The shell ships no copy and reads no locale state — all text arrives from registrants (ui-settings-general owns chrome and General; features own their sections and rows), so the section ledger bump is its only re-render trigger.

The `deepseek` → `deepseek-official` provider-route rename rides along as the enabling breaking change.
 
 ## Problem
 
@@ -18,17 +18,19 @@ PR1 made LLM adapter configuration restart-free at the seam, but the only writer
 
 **The llm seam declares configurability and announces topology.** `registerConfigurableProviders()` is an all-or-nothing, fiber-scoped directory of `{provider, displayName, settingsNs, settingsPath}` — the addressing a config page needs to open the right settings subtree for a route that may not exist yet; `listConfigurableProviders()` merges with live routes in the wire handler so undeclared live routes still report active. The zero-payload `'llm/adapters-updated'` event fires from all four registration/unregistration commit points with contained listener dispatch (INVARIANT rethrow), following the settings/commands precedent. `llm-deepseek`'s route renamed to `deepseek-official` because the pi-ai catalog legitimately owns `deepseek` as an aggregator entry; pre-release stance, no alias.
 
-**A standalone schema-driven form renderer.** `dsh-client-schema-form` rehydrates the wire's `toJSON()` envelope into live schemastery nodes and renders by structural classification: objects/dicts/arrays recurse, all-literal unions become selects (an absent value shows `Default: X` from the fallback layer), dict key-unions feed the add-entry vocabulary, and anything it cannot faithfully edit renders as read-only JSON — visible, never dropped. Presence-in-draft drives the override badge and per-field Reset; a `renderField` hook lets consumers mount role-specific controls without the renderer knowing any role.
+**A hand-written editor over a schema model layer.** `dsh-client-schema-form` rehydrates the wire's `toJSON()` envelope into live schemastery nodes for validation, path resolution, and immutable draft editing — but no generic rendering: the first cut shipped a full schema-driven form renderer, and the resulting page was an unstyled schema dump (every advanced field flattened onto the card, raw field names as labels, the `retryPolicy` unsupported-fallback in the main flow). The user chose the hand-written direction over adding a hint/grouping system, and a second round removed the reference input entirely: the card's primary field is one **API key** input, a whole-section provider without a configured key opens as its setup card, and the collapsed 自定义设置 fold carries the curated per-family extras (`baseURL` for both families, plus `reasoningEffort` for deepseek / `reasoning` for pi-ai), with every other field owned by `settings.yaml`. Validation still runs the rehydrated schema before writing, so a hand-coded field that drifts from its schema fails loud on save rather than silently.
 
-**The Models page is a three-domain join with seam-shaped apply semantics.** Rows are configured providers; the add vocabulary is the dormant directory remainder; badges come from route liveness and the credential reference's value-free `configured` state. The `credential-ref` role mounts the credential control: reference name in settings, key value **write-only** through `credentials.set`. An edit without removals lands as a minimal `settings.update` merge patch (stored secrets outside the patch survive); a field reset or row deletion replaces the whole user section via `settings.replace`, because merge semantics cannot express removal.
+**The Models page is a three-domain join with seam-shaped apply semantics.** Rows are configured providers; the add card's select is the dormant directory remainder; badges come from route liveness. The key path stays reference-shaped without ever showing a reference: a typed key stores **write-only** through `credentials.set` under the profile's `apiKeyEnv`, deriving `<ROUTE>_API_KEY` when none exists (the pi-ai profile records the derivation), so `settings.yaml` never carries a key value and the wholesale `settings.replace` a removal needs can never drop a sibling's secret. An edit without removals lands as a minimal `settings.update` merge patch; clearing a fold field back to inherited or deleting a row replaces the whole user section, because merge semantics cannot express removal.
 
 ## Alternatives considered
 
 - **Serving JSON Schema over the wire** — schemastery's `toJSON()` envelope round-trips `role()`/meta and rehydrates into the validator the client already ships for drafts; converting to JSON Schema loses exactly the role annotations the credential control and secret redaction key on.
+- **A generic schema-driven form renderer** — implemented first, then replaced: field truth without visual hierarchy produced an ugly, unusable card, and making it good meant building a hint vocabulary (primary/advanced grouping, per-field descriptions, array item cards) rivaling the hand-written editor in cost while still fitting no mockup exactly. Two schemas exist today (the deepseek `Config` and the shared pi-ai profile), so hand-writing is two thin namespace-keyed layouts; the drift risk is bounded by save-time schema validation and by unknown fields staying untouched in the document.
 - **Masking secrets per-field with sentinel backfill on `replace`** — the PR1 decision (secrets are references) already deleted the stored-literal case for the product default; structural redaction plus a write-only credential path handles the residue without teaching every writer a sentinel protocol.
+- **Storing the typed key as a literal `apiKey` setting** — the v1 "one API key input" requirement could have written the literal into the profile, but every UI removal path rebuilds the user section from the *redacted* layers, so any reset or row deletion would silently drop stored sibling keys; deriving a reference keeps the input single-field while keeping `settings.yaml` secret-free and every replace safe.
 - **A `models` bridge plugin owning provider configuration** — same rejection as PR1: per-plugin namespaces plus a four-field directory declaration give the UI everything it needs; the bridge's unified dict re-imports the adapter-mapping indirection.
 - **Page-side polling instead of pushed frames** — the mux already carries `host/commands-changed`; three more frames cost one shape each and make a second tab, an external `settings.yaml` edit, and a settings-born route converge at event speed.
 
 ## Consequences
 
-The whole loop is pinned keyless in the browser lane (`apps/web/tests/models-settings.e2e.ts`): the dormant pi-ai catalog renders as add vocabulary, adding `anthropic` writes `settings.yaml` and the route registers live on the topology frame, the key stores write-only into the harness home's `.env`, and the badge converges from the credentials frame — zero model calls, ARIA goldens for the empty and configured states, plus a scaffold `harnessHome` so tests never touch a real `~/.dsh`. The rename touched 239 files (fixtures, goldens, docs, python) in one commit with no compatibility alias. Deferred: a per-row models preview (the picker already lists models), a page address for live routes that never declared configurability, and the documented reset edge — a `settings.replace` cannot re-supply a stored *literal* secret in the replaced subtree, which the reference-based default makes unreachable.
+The whole loop is pinned keyless in the browser lane (`apps/web/tests/models-settings.e2e.ts`): the add card offers the dormant pi-ai catalog, adding `minimax-cn` with a typed key writes the reference-only profile into `settings.yaml`, stores the value into the harness home's `.env` under the derived `MINIMAX_CN_API_KEY`, registers the route live on the topology frame, and the customized fold merges `reasoning` beside the reference — zero model calls, ARIA goldens for the add-card and configured states, plus a scaffold `harnessHome` so tests never touch a real `~/.dsh` (the provider under test is one whose derived reference cannot collide with a developer's exported keys). The rename touched 239 files (fixtures, goldens, docs, python) in one commit with no compatibility alias. The renderer replacement cost one commit and no wire change: apply semantics, redaction, and the directory join were renderer-agnostic all along. Deferred: a per-row models preview (the picker already lists models), a page address for live routes that never declared configurability, and the documented reset edge — a `settings.replace` cannot re-supply a stored *literal* secret in the replaced subtree, which the reference-based default makes unreachable.

@@ -18,17 +18,19 @@ PR1 让 LLM（大语言模型）适配器配置在 seam 层面免重启，但唯
 
 **llm seam 声明可配置性并公布拓扑。**`registerConfigurableProviders()` 是一个全有或全无、以 fiber 为作用域的目录，条目为 `{provider, displayName, settingsNs, settingsPath}`——这正是配置页要为一条可能尚不存在的路由打开正确设置子树时所需要的寻址；`listConfigurableProviders()` 在 wire 处理器里与存活路由合并，未声明的存活路由因此仍报告为激活。零负载的 `'llm/adapters-updated'` 事件从全部四个注册／注销提交点触发，listener 派发带异常隔离（INVARIANT 重抛），沿用 settings/commands 的先例。`llm-deepseek` 的路由重命名为 `deepseek-official`，因为 pi-ai catalog 名正言顺地拥有 `deepseek` 这个聚合器条目；依预发布立场，不设别名。
 
-**独立的 schema 驱动表单渲染器。**`dsh-client-schema-form` 把 wire 的 `toJSON()` 信封还原（rehydrate）为活的 schemastery 节点，并按结构分类渲染：object/dict/array 递归展开，全字面量联合成为下拉框（值缺失时显示取自回退层的 `Default: X`），dict 的键联合供给「新增条目」的词汇，凡是无法忠实编辑的一律渲染为只读 JSON——保持可见，绝不丢弃。「是否出现在草稿中」驱动覆盖徽标与逐字段 Reset；`renderField` 钩子让消费方挂载角色专属控件，渲染器自身不必认识任何角色。
+**架在 schema 模型层之上的手写编辑器。**`dsh-client-schema-form` 把 wire 的 `toJSON()` 信封还原（rehydrate）为活的 schemastery 节点，用于校验、路径解析与不可变草稿编辑——但不做通用渲染：第一版交付了完整的 schema 驱动表单渲染器，得到的却是一个未加样式、把 schema 原样倾倒出来的页面（每个进阶字段都平铺到卡片上、原始字段名直接充当标签、`retryPolicy` 的「不支持」回退落在主流程里）。用户没有再加一套提示／分组系统，而是选择了手写方向，第二轮又把引用输入框整个移除：卡片的主字段是一个 **API 密钥**输入框，未配置密钥的整分节提供方会以其设置卡片的形式打开，收起的「自定义设置」折叠区承载按家族精选的额外字段（两个家族都有 `baseURL`，另加 deepseek 的 `reasoningEffort`／pi-ai 的 `reasoning`），其余每个字段都归 `settings.yaml` 所有。校验仍会在写入前运行还原出的 schema，因此偏离其 schema 的手写字段会在保存时大声失败，而非静默失败。
 
-**Models 页是一次三领域联接，应用语义与 seam 同形。**每一行是一个已配置的提供方；「新增」词汇是可配置提供方目录中剩余的休眠条目；徽标来自路由存活状态与凭据引用不含值的 `configured` 状态。`credential-ref` 角色挂载凭据控件：引用名进设置，密钥值经 `credentials.set` **只写**存入。不含删除的编辑以一次最小的 `settings.update` 合并 patch 落地（patch 之外已存储的机密得以保留）；字段重置或整行删除则经 `settings.replace` 替换整个用户分节，因为合并语义表达不了删除。

 ## 曾考虑的替代方案
 
 - **在 wire 上改发 JSON Schema**——schemastery 的 `toJSON()` 信封能往返保留 `role()`/meta，并还原成客户端为草稿校验本就自带的那个校验器；转换成 JSON Schema 丢掉的恰恰是凭据控件与 secret 脱敏所依赖的角色注解。
+- **通用的 schema 驱动表单渲染器**——先实现、后被替换：如实呈现字段却缺失视觉层级，产出的卡片丑陋且不可用；要把它做好，就意味着构建一套提示词汇（主要／进阶分组、逐字段描述、数组项卡片），成本堪比手写编辑器，却仍无法与任何设计稿完全吻合。今天存在两份 schema（deepseek 的 `Config` 与共享的 pi-ai profile），手写因此就是两套以 namespace 为键的薄布局；漂移风险由保存时的 schema 校验以及未知字段在文档中的原样保留共同约束。
 - **逐字段脱敏机密并在 `replace` 时回填哨兵值**——PR1 的决策（机密是引用）已经为产品默认形态删掉了「存储字面量」这种情况；结构化脱敏加上只写的凭据通道足以处理残余情形，无需让每个写入方都学会一套哨兵协议。
+- **把键入的密钥存成字面 `apiKey` 设置**——v1「单个 API 密钥输入框」的需求本可以把字面量直接写进 profile，但 UI 的每条删除路径都会从*脱敏后的*各层重建用户分节，任何重置或整行删除都会静默丢掉已存储的兄弟密钥；派生引用让输入保持单字段，同时让 `settings.yaml` 不含机密、每一次 replace 都安全。
 - **由 `models` 桥接插件持有提供方配置**——与 PR1 相同的否决理由：按插件划分的 namespace 加上四字段的目录声明已经给了 UI 需要的一切；桥接层的统一字典会把适配器映射那层间接重新引进来。
 - **页面侧轮询而非推送帧**——mux 已经承载 `host/commands-changed`；再加三个帧各自只多一个形状的成本，就让第二个标签页、外部的 `settings.yaml` 编辑和由设置催生的路由都以事件速度收敛。
 
 ## 后果
 
-整条闭环以无密钥方式固定在浏览器测试通道（`apps/web/tests/models-settings.e2e.ts`）：休眠的 pi-ai catalog 渲染为「新增」词汇，添加 `anthropic` 会写入 `settings.yaml`、路由随拓扑帧注册为存活，密钥只写存入 harness 家目录的 `.env`，徽标随凭据帧收敛——全程零模型调用，空态与已配置态各有 ARIA golden，另有脚手架式的 `harnessHome`，测试绝不触碰真实的 `~/.dsh`。这次重命名在一次提交中触及 239 个文件（fixture（测试前置数据）、golden、文档、python），未保留兼容别名。延后事项：每行的模型预览（选择器已能列出模型）、为从未声明可配置性的存活路由提供页面地址，以及已记录在案的重置边界情形——`settings.replace` 无法在被替换的子树里重新补上已存储的*字面量*机密，而基于引用的默认形态让这种情况根本无从出现。

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

 「应用」语义与 settings seam 呈镜像：不含删除的编辑以最小的 `settings.update` 合并 patch 落地，把折叠区字段清回继承值或删除整行则经对整个用户分节的 `settings.replace` 落地，使删除真正生效——整体替换是安全的，因为该分节存的是密钥引用，从不存密钥值。页面加载完成后会在推送的失效事件（`settings/changed`、`credentials/changed`、`models/changed` 与 `connection/reset`）上重拉，因此外部的 `settings.yaml` 编辑、第二个标签页或 settings 新生的路由都无需轮询即可收敛。

Your task is to translate the given source document from English to Chinese, producing natural, professional technical prose.\n\n## Quality Requirements\n\n### Structure and Format Preservation\n- Output a complete translated document that maintains exactly the same structure as the source: heading hierarchy, list shape, table columns, link targets, and code blocks.\n- Fenced code blocks must be byte-identical to the source, including ALL comments inside them. Do NOT translate comments inside code blocks. This is a hard rule with no exceptions.\n- Inline code spans (commands, flags, paths, API names, version numbers) must be kept verbatim. Never translate or reformat them.\n- Every relative link must point to the same target as in the source. Link text is translated; link targets are not.\n- Language switcher line: when translating into Chinese, write `[English](source-filename.md) | 中文`. When translating into English, write `English | [中文](source-filename.zh.md)`. Do NOT copy the switcher line from the source file unchanged — you must flip the link direction.\n- After a closing bold marker `**`, insert a space before the next character when that character is a Latin letter, digit, or CJK ideograph. Never insert a space before any punctuation (full-width or half-width).\n\n### Tone and Style\n- The translation must read as if originally written in the target language by a native speaker. If an expression sounds like a word-for-word rendering from the source language, rephrase it.\n- Write in a professional, formal tone appropriate for developer documentation. Never use colloquial or casual expressions.\n- Use polite imperative forms where the text instructs the reader to do something.\n- Keep the author's register: concise stays concise, detailed stays detailed.\n\n### Sentence Structure\n- Break long sentences with commas or semicolons. Avoid run-on sentences.\n- Prefer active voice. Convert passive constructions to active if it reads more naturally.\n- Translate meaning, not words. Restructure sentences where the target language grammar requires it.\n- Do not invent words or expressions that do not exist in natural technical writing of the target language.\n\n### Word Choice\n- Prefer precise, formal vocabulary over casual or colloquial alternatives.\n- When multiple synonyms exist, choose the one most commonly used in professional technical documentation of the target language.\n- Avoid slang, internal jargon, or overly literal translations that would not be recognized by the general developer audience.\n- Do not use the same word to translate two different source-language terms that carry distinct meanings.\n- Avoid repeating the same verb in close proximity; vary word choice for readability.\n\n#### When translating into Chinese\n- When a number modifies a noun, always include a Chinese classifier or measure word (量词). For example: \"three-package seam\" → \"由三个包构成的 seam\", not \"三包 seam\".\n\n### Punctuation\n\n#### When translating into Chinese\n- Use full-width Chinese punctuation in prose: `，。：；？！（）「」`.\n- Strongly prefer replacing all em-dashes (——) with colons, periods, commas, or parentheses. Keep an em-dash only if no other punctuation works at all.\n- Use enumeration commas (、) between parallel items, not regular commas.\n- List item endings: use semicolons or no punctuation. Do not end list items with commas.\n- Put one half-width space between Chinese text and Latin words/numbers.\n- For RFC 2119 keywords (MUST, MUST NOT, SHOULD, MAY), translate to the corresponding Chinese term (必须、禁止、应当、可以) and keep the SOURCE emphasis marker: plain source stays plain (必须), italic source stays italic (*必须*), and bold source stays bold (**必须**).\n\n#### When translating into English\n(To be added.)\n\n## Terminology\n\nA terminology table is provided below. Follow it strictly:\n- Render every listed term exactly as specified.\n- When the target language is Chinese, use the \"中文\" column. On first occurrence, write the \"首次出现\" value with its parenthetical gloss; on subsequent occurrences, write only the part before the parentheses.\n- When the target language is English, use the \"English\" column without a Chinese gloss; do not copy the \"中文\" or \"首次出现\" value into English prose.\n- If a term has already been glossed as part of a compound term, do not gloss it again when it appears alone later.\n- NEVER use translations listed in the \"不要译作\" column.\n- For technical terms not in the table, follow the target language: for a Chinese target, use an established Chinese rendering from a major Chinese-language OSS or vendor source, or keep the source term and flag it as pending when no such precedent exists; for an English target, use the established English technical term, or preserve an ambiguous source term with a short English gloss and flag it as pending. Do not invent a translation. This rule applies to terminology only; for general prose, freely restructure and paraphrase for natural expression.\n\n# Terminology\n\n本表约定本仓库的中英术语统一译法。\n\n**通用规则：**\n- \"中文\"列为中文译文的正文默认用词。若该列为英文，则中文译文的正文中保留英文不翻译。\n- 首次出现按\"首次出现\"列书写（带括号注释）；后续出现只写括号前的部分（可能为中文，也可能为英文），不出现括号内的注释。\n- \"不要译作\"列为严格禁止的译法。\n- 如果某术语已经作为另一个术语的组成部分被括注过（如 `agent loop（智能体循环）` 中已包含 `agent` 的括注），则该术语后续单独出现时无需再次括注。\n\n## 缩写类（中英文文本中均使用缩写）\n\n| English | 中文 | 首次出现 | 不要译作 | 备注 |\n|---|---|---|---|---|\n| ACP | ACP | ACP（Agent Client Protocol） | | |\n| AI | AI | AI（人工智能） | | |\n| API | API |

tags are framing. If Markdown inside any section body contains a line consisting only of `<translation>`, `</translation>`, `<review>`, `</review>`, `<final>`, or `</final>`, prefix that line with `\\`. If the original line already has one or more backslashes immediately before the tag, add one more. The parser removes exactly one framing escape; tags mentioned inline need no escaping.\n\n```xml\n<translation>\n(Complete translation of the source document)\n</translation>\n\n<review>\n(Self-review notes, one correction per line with category tag, e.g.)\n- [Tone] \"旁挂记录\" → \"伴随记录\"（生造词）\n- [Sentence] 第 3 段补充逗号断句\n- [Punctuation] 两处破折号替换为冒号\n- 无修正\n</review>\n\n<final>\n(Final translation after corrections)\n</final>\n```\n\n## Self-Review Instructions\n\nAfter writing `<translation>`, re-read it in the target language only, without looking at the source. Check by category:\n\n**Structure**\n- Is the heading hierarchy, list shape, and code block content identical to the source?\n- Are ALL comments inside code blocks left untranslated (byte-identical to source)?\n- Is the language switcher line correctly flipped (not copied from source)?\n- Are link targets preserved, and are spaces after bold markers present only before Latin letters, digits, or CJK ideographs?\n- Are wrapper-tag lines inside section bodies escaped with one additional backslash?\n\n**Tone & Style**\n- Does every sentence read as if originally written by a native speaker?\n- Is there any colloquial, casual, or overly informal phrasing?\n\n**Sentence Structure**\n- Are there run-on sentences that need breaking?\n- Are there stiff passive constructions that should be converted to active voice?\n\n**Word Choice**\n- Are there overly literal translations that sound unnatural?\n- Is the same target-language word used to translate two distinct source concepts?\n- Is any slang or internal jargon present?\n\n**Terminology**\n- For a Chinese target, are first-occurrence glosses correctly applied (not missing, not repeated)? For an English target, are Chinese glosses absent?\n- Are any \"不要译作\" forbidden translations present?\n- For unlisted terms, does a Chinese target use established Chinese precedent or retain the source term as pending, and does an English target use established English terminology or preserve only an ambiguous source term with a short English gloss?\n\n**Punctuation** (when target is Chinese)\n- Are there em-dashes that should be replaced with colons, periods, or commas?\n- Are list items ending with commas instead of semicolons?\n- Do RFC 2119 keywords preserve the source emphasis exactly?\n\nRecord corrections in `<review>` with category tags. Then output the corrected version in `<final>`. If no corrections are needed, write \"无修正\" in `<review>` and copy the translation unchanged into `<final>`.\n\n## Examples\n\nBelow are representative examples of common problems and their corrections. Follow the \"Good\" versions.\n\n### Colloquial verb → Professional verb\n- Source: `The repo pins pnpm@11.7.0 in package.json`\n- Bad: `仓库在 package.json 中钉住 pnpm@11.7.0`\n- Good: `该仓库在 package.json 中固定使用 pnpm@11.7.0`\n\n### Run-on sentence → Natural phrasing with pause\n- Source: `Read docs/architecture.md before changing anything under packages/.`\n- Bad: `改动 packages/ 下的任何东西之前先读 docs/architecture.md。`\n- Good: `在修改 packages/ 目录下的任何内容之前，请先阅读 docs/architecture.md。`\n\n### Stiff passive voice → Active and natural\n- Source: `a green gate means the pair was confirmed consistent at these exact contents, not that the confirmation was sound.`\n- Bad: `门禁绿意味着这对文档曾在当前内容上被确认一致，不意味着这次确认本身是对的。`\n- Good: `门禁通过意味着这组文档在当前内容上的一致性得到了确认，不代表确认本身正确可靠。`\n\n### Invented word → Natural expression\n- Source: `A sidecar record of both blob hashes makes consistency checkable`\n- Bad: `旁挂记录两侧 blob hash，使一致性可检查`\n- Good: `伴随记录保存两侧 blob hash，使一致性可检查`\n\n### Em-dash → Colon/period\n- Source: `FIXME — an issue that should block a new release. A release should not ship with an open FIXME unless reviewers explicitly agree the change can be merged anyway.`\n- Bad: `FIXME——应当阻塞新版本发布的问题。除非评审者明确同意可以照常合入，发布不应带着未解决的 FIXME 出门。`\n- Good: `FIXME：应当阻塞新版本发布的问题。除非评审者明确同意该更改可以合并，否则发布版本不应包含未解决的 FIXME。`\n\n### Overly literal → Meaningful rendering\n- Source: `awkward phrasing is easier to hear without the source anchoring you`\n- Bad: `没有源文锚着，别扭的表述更容易被听出来`\n- Good: `不对照原文时，更容易察觉别扭的表达`\n\n### Terminology — do not translate what should be kept in English\n- Source: `typed service seams, and explicit extension points`\n- Bad: `类型化的服务 seam（扩展点）与显式扩展点`\n- Good: `类型化的服务 seam 与显式扩展点`\n\n### Slang/jargon → Professional phrasing\n- Source: `The committed agent workflow lives in .agents/skills/dsh-translate-docs`\n- Bad: `进仓的 agent 工作流见 .agents/skills/dsh-translate-docs`\n- Good: `仓库内置的 agent 工作流见 .agents/skills/dsh-translate-docs`\n\n### \"For humans\" — translate the intent, not the word\n- Source: `For humans, start with the development guide`\n- Bad: `对于人工读者，请先从开发指南开始`（\"人工读者\"生硬）\n- Good: `面向开发者：请先阅读开发指南`（\"开发者\"自然，且中文里冒号在此处更自然）\n\n### Code block comments — NEVER translate\n- Source code block contains: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)`\n- Bad: `# 全屏 TUI coding agent（需要 DEEPSEEK_API_KEY）`\n- Good: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)` (keep exactly as-is, byte-for-byte)\n\n### Language switcher — flip direction\n- Source file (English) has: `English | [中文](README.zh.md)`\n- Bad (copying source unchanged): `English | [中文](README.zh.md)`\n- Good (flipped for Chinese file): `[English](README.md) | 中文`\n\n---\n\nNow translate the following document:"

On first occurrence, write the \"首次出现\" value with its parenthetical gloss; on subsequent occurrences, write only the part before the parentheses.\n- When the target language is English, use the \"English\" column without a Chinese gloss; do not copy the \"中文\" or \"首次出现\" value into English prose.\n- If a term has already been glossed as part of a compound term, do not gloss it again when it appears alone later.\n- NEVER use translations listed in the \"不要译作\" column.\n- For technical terms not in the table, follow the target language: for a Chinese target, use an established Chinese rendering from a major Chinese-language OSS or vendor source, or keep the source term and flag it as pending when no such precedent exists; for an English target, use the established English technical term, or preserve an ambiguous source term with a short English gloss and flag it as pending. Do not invent a translation. This rule applies to terminology only; for general prose, freely restructure and paraphrase for natural expression.\n\n# Terminology\n\n本表约定本仓库的中英术语统一译法。\n\n**通用规则：**\n- \"中文\"列为中文译文的正文默认用词。若该列为英文，则中文译文的正文中保留英文不翻译。\n- 首次出现按\"首次出现\"列书写（带括号注释）；后续出现只写括号前的部分（可能为中文，也可能为英文），不出现括号内的注释。\n- \"不要译作\"列为严格禁止的译法。\n- 如果某术语已经作为另一个术语的组成部分被括注过（如 `agent loop（智能体循环）` 中已包含 `agent` 的括注），则该术语后续单独出现时无需再次括注。\n\n## 缩写类（中英文文本中均使用缩写）\n\n| English | 中文 | 首次出现 | 不要译作 | 备注 |\n|---|---|---|---|---|\n| ACP | ACP | ACP（Agent Client Protocol） | | |\n| AI | AI | AI（人工智能） | | |\n| API | API |

If Markdown inside any section body contains a line consisting only of `<translation>`, `</translation>`, `<review>`, `</review>`, `<final>`, or `</final>`, prefix that line with `\\`. If the original line already has one or more backslashes immediately before the tag, add one more. The parser removes exactly one framing escape; tags mentioned inline need no escaping.\n\n```xml\n<translation>\n(Complete translation of the source document)\n</translation>\n\n<review>\n(Self-review notes, one correction per line with category tag, e.g.)\n- [Tone] \"旁挂记录\" → \"伴随记录\"（生造词）\n- [Sentence] 第 3 段补充逗号断句\n- [Punctuation] 两处破折号替换为冒号\n- 无修正\n</review>\n\n<final>\n(Final translation after corrections)\n</final>\n```\n\n## Self-Review Instructions\n\nAfter writing `<translation>`, re-read it in the target language only, without looking at the source. Check by category:\n\n**Structure**\n- Is the heading hierarchy, list shape, and code block content identical to the source?\n- Are ALL comments inside code blocks left untranslated (byte-identical to source)?\n- Is the language switcher line correctly flipped (not copied from source)?\n- Are link targets preserved, and are spaces after bold markers present only before Latin letters, digits, or CJK ideographs?\n- Are wrapper-tag lines inside section bodies escaped with one additional backslash?\n\n**Tone & Style**\n- Does every sentence read as if originally written by a native speaker?\n- Is there any colloquial, casual, or overly informal phrasing?\n\n**Sentence Structure**\n- Are there run-on sentences that need breaking?\n- Are there stiff passive constructions that should be converted to active voice?\n\n**Word Choice**\n- Are there overly literal translations that sound unnatural?\n- Is the same target-language word used to translate two distinct source concepts?\n- Is any slang or internal jargon present?\n\n**Terminology**\n- For a Chinese target, are first-occurrence glosses correctly applied (not missing, not repeated)? For an English target, are Chinese glosses absent?\n- Are any \"不要译作\" forbidden translations present?\n- For unlisted terms, does a Chinese target use established Chinese precedent or retain the source term as pending, and does an English target use established English terminology or preserve only an ambiguous source term with a short English gloss?\n\n**Punctuation** (when target is Chinese)\n- Are there em-dashes that should be replaced with colons, periods, or commas?\n- Are list items ending with commas instead of semicolons?\n- Do RFC 2119 keywords preserve the source emphasis exactly?\n\nRecord corrections in `<review>` with category tags. Then output the corrected version in `<final>`. If no corrections are needed, write \"无修正\" in `<review>` and copy the translation unchanged into `<final>`.\n\n## Examples\n\nBelow are representative examples of common problems and their corrections. Follow the \"Good\" versions.\n\n### Colloquial verb → Professional verb\n- Source: `The repo pins pnpm@11.7.0 in package.json`\n- Bad: `仓库在 package.json 中钉住 pnpm@11.7.0`\n- Good: `该仓库在 package.json 中固定使用 pnpm@11.7.0`\n\n### Run-on sentence → Natural phrasing with pause\n- Source: `Read docs/architecture.md before changing anything under packages/.`\n- Bad: `改动 packages/ 下的任何东西之前先读 docs/architecture.md。`\n- Good: `在修改 packages/ 目录下的任何内容之前，请先阅读 docs/architecture.md。`\n\n### Stiff passive voice → Active and natural\n- Source: `a green gate means the pair was confirmed consistent at these exact contents, not that the confirmation was sound.`\n- Bad: `门禁绿意味着这对文档曾在当前内容上被确认一致，不意味着这次确认本身是对的。`\n- Good: `门禁通过意味着这组文档在当前内容上的一致性得到了确认，不代表确认本身正确可靠。`\n\n### Invented word → Natural expression\n- Source: `A sidecar record of both blob hashes makes consistency checkable`\n- Bad: `旁挂记录两侧 blob hash，使一致性可检查`\n- Good: `伴随记录保存两侧 blob hash，使一致性可检查`\n\n### Em-dash → Colon/period\n- Source: `FIXME — an issue that should block a new release. A release should not ship with an open FIXME unless reviewers explicitly agree the change can be merged anyway.`\n- Bad: `FIXME——应当阻塞新版本发布的问题。除非评审者明确同意可以照常合入，发布不应带着未解决的 FIXME 出门。`\n- Good: `FIXME：应当阻塞新版本发布的问题。除非评审者明确同意该更改可以合并，否则发布版本不应包含未解决的 FIXME。`\n\n### Overly literal → Meaningful rendering\n- Source: `awkward phrasing is easier to hear without the source anchoring you`\n- Bad: `没有源文锚着，别扭的表述更容易被听出来`\n- Good: `不对照原文时，更容易察觉别扭的表达`\n\n### Terminology — do not translate what should be kept in English\n- Source: `typed service seams, and explicit extension points`\n- Bad: `类型化的服务 seam（扩展点）与显式扩展点`\n- Good: `类型化的服务 seam 与显式扩展点`\n\n### Slang/jargon → Professional phrasing\n- Source: `The committed agent workflow lives in .agents/skills/dsh-translate-docs`\n- Bad: `进仓的 agent 工作流见 .agents/skills/dsh-translate-docs`\n- Good: `仓库内置的 agent 工作流见 .agents/skills/dsh-translate-docs`\n\n### \"For humans\" — translate the intent, not the word\n- Source: `For humans, start with the development guide`\n- Bad: `对于人工读者，请先从开发指南开始`（\"人工读者\"生硬）\n- Good: `面向开发者：请先阅读开发指南`（\"开发者\"自然，且中文里冒号在此处更自然）\n\n### Code block comments — NEVER translate\n- Source code block contains: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)`\n- Bad: `# 全屏 TUI coding agent（需要 DEEPSEEK_API_KEY）`\n- Good: `# full-screen TUI coding agent (needs DEEPSEEK_API_KEY)` (keep exactly as-is, byte-for-byte)\n\n### Language switcher — flip direction\n- Source file (English) has: `English | [中文](README.zh.md)`\n- Bad (copying source unchanged): `English | [中文](README.zh.md)`\n- Good (flipped for Chinese file): `[English](README.md) | 中文`\n\n---\n\nNow translate the following document:"
       },
       {
         "role": "user",

 **The settings shell contributes navigation state, not provider policy.** `ui-settings` declares a root-scoped `settings.onboarding` list slot and tells registrants whether the current surface is the empty Hero. Its private `openSection(id)` callback opens the settings panel on one registered section. `ui-models` registers the DeepSeek overlay through the same declaration-aware deferred-registration path as its Models section, so plugin load order does not become a contract.
 
-**The prompt is a credential-only write path.** A mounted, active adapter with a resolved, writable, unconfigured reference presents a password input. Submit calls only `credentials.set({ref, value})`, clears the React draft after success, refetches the shared join, and closes only when the new descriptor reports `configured: true`. Business failures and transport rejections keep the dialog open, restore its busy state in `finally`, and redact the submitted value from rendered error text. The prompt never writes `apiKey`, `baseURL`, or a redacted settings section; advanced configuration opens Models instead.
+**The prompt routes to the one credential editor.** A mounted, active adapter with a resolved, writable, unconfigured reference presents one action that opens Settings on Models. The existing DeepSeek setup card there exclusively owns the password input, `credentials.set({ref, value})`, write failures, and post-write refresh; the onboarding overlay never holds or submits a secret. An unavailable settings or credential capability keeps its deployment diagnostic and routes to the same page, while an absent adapter remains skipped because navigation cannot mount a Cordis plugin.
 
 **Unavailable capability states stay honest.** An absent configurable-provider entry suppresses the form because it cannot repair the composition. A present provider whose settings or credential capability cannot be resolved renders an actionable deployment diagnostic. Cancel dismisses the overlay for the current mounted surface and writes no completion fact. Settings, credential, provider-topology, and connection invalidations all refresh the shared join, so an external credential update closes an open prompt without a reload.

+**A second API-key editor inside onboarding** — rejected because the Models page already renders its DeepSeek setup card for exactly this state. Duplicating its secret draft, write errors, and configured-state convergence would add a second security-sensitive UI without another user capability.
+
 **Writing the API key into provider settings** — rejected because a literal secret would enter the settings mutation path and whole-section replacement cannot safely reconstruct redacted values. Credential storage is already the product seam and supplies immediate invalidation.
 
 **Showing the same key form when `llm-deepseek` is absent** — rejected because success would only store an unused environment reference; the browser has no supported operation that mounts the missing Cordis plugin.
 
 ## Consequences
 
-The first-run flow now repairs the shipped adapter without restarting: a keyless browser test boots the real Web composition under an isolated harness home, observes the dialog, stores a generated key into that home's `.env`, verifies no key reaches DOM, ARIA, or browser console output, and confirms the running Models page reports configured. Pure readiness and React tests pin literal, file, process-environment, missing-provider, missing-capability, business-error, transport-error, cancellation, and external-invalidation behavior. The flow deliberately inherits the configuration plane's documented base limitations rather than adding local secret storage, redaction, or settings replacement workarounds.

-Models settings plugin: the provider configuration page and official-DeepSeek first-run credential overlay. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
+Models settings plugin: the provider configuration page and official-DeepSeek first-run routing overlay. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
 
 Rows are the *configured* providers (their profile resolves in the owning namespace); a whole-section provider whose key is not configured anywhere (the first-run DeepSeek posture) renders as its open setup card instead of a row, and the add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor is a hand-written card per adapter family: the primary field is a single **API key** input — the page never asks for an environment-variable name; a typed key stores **write-only** through `credentials.set` under the profile's reference, deriving `<ROUTE>_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. The collapsed 自定义设置 fold carries the curated extras — `baseURL` for both families (the deepseek placeholder shows the public endpoint), plus `reasoningEffort` (deepseek) or `reasoning` (pi-ai); every other profile field stays owned by `settings.yaml`. A row is deletable only when the user layer alone carries it (removal restores the composition base).
 
-The first-run overlay projects `deepseek-official` readiness from that same joined snapshot. A configured literal `apiKey` secret sidecar or configured credential reference suppresses the prompt, including a read-only launch-environment credential. A mounted adapter with a writable missing reference opens the password form and writes only through `credentials.set`; success is accepted only after a fresh describe reports configured. An absent adapter is skipped because a browser form cannot mount Cordis plugins, while a present but unusable settings or credential capability produces a deployment diagnostic and an advanced link opens the Models section.
+The first-run overlay projects `deepseek-official` readiness from that same joined snapshot. A configured literal `apiKey` secret sidecar or configured credential reference suppresses the prompt, including a read-only launch-environment credential. A mounted adapter with a missing writable reference shows one action that opens Settings on the Models section, whose existing setup card exclusively owns key input and `credentials.set`; the overlay never holds a secret. An absent adapter is skipped because browser navigation cannot mount Cordis plugins, while an unusable settings or credential capability produces a deployment diagnostic with the same route to Models.
 
 Apply semantics mirror the settings seam: an edit without removals lands as a minimal `settings.update` merge patch, while clearing a fold field back to inherited or deleting a row lands through `settings.replace` of the whole user section so removals actually take effect — safe wholesale, because the section stores key references, never key values. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.

 行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；密钥未在任何地方配置的整分节提供方（DeepSeek 的首次运行姿态）会渲染为其展开的设置卡片而非一行，「新增」流程则是一张承载休眠目录提供方选择框的卡片——裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器是每个适配器家族各一张的手写卡片：主字段是单独一个 **API 密钥**输入框——页面从不询问环境变量名；键入的密钥经 `credentials.set` 以**只写**方式存入 profile 的引用之下，profile 没有引用时便派生 `<ROUTE>_API_KEY`，pi-ai profile 会把这次派生记录为 `apiKeyEnv`，因此 `settings.yaml` 从不携带密钥值。收起的「自定义设置」折叠区承载精选的额外字段——两个家族都有 `baseURL`（deepseek 的占位符显示公共端点），另加 `reasoningEffort`（deepseek）或 `reasoning`（pi-ai）；其余每个 profile 字段仍归 `settings.yaml` 所有。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。
 
-首次使用浮层从同一个联接快照得出 `deepseek-official` 的就绪状态。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，浮层就不再显示，其中包括来自启动环境且只读的凭据。适配器已挂载、引用可写但尚未配置时，浮层会打开密码表单，且只经 `credentials.set` 写入；只有重新调用 describe 并确认已配置后，才会接受此次提交。适配器缺失时直接跳过，因为浏览器表单无法挂载 Cordis 插件；提供方存在但设置或凭据能力不可用时，则显示部署诊断，并通过高级设置链接打开 Models 分区。

From: Yichen Jiang <jyc132780208@sina.com>
Date: Thu, 30 Jul 2026 15:40:09 +0800
Subject: [PATCH 032/102] fix(credentials-local): one operation chain,
 read-modify-write under the shared writer lock, and a quote-aware line editor

Review round three, credentials half. dsh-atomic-write grows the
cross-process writer-lock primitive (withFileLock: wx sentinel, bounded
backoff, stale takeover via onStaleBreak, deadline failure) plus a dirMode
option, and settings-local migrates its private copy to it; both providers
now create harness-home directories 0700.

credentials-local reuses the reviewed settings-local shape: watcher
reloads and line edits share one settled operation chain; every write
re-reads the document under the lock and publishes unobserved external
entries before editing, so an edit inside the debounce window (or another
process's write) can never be overwritten; the watcher's ready signal
queues one reconcile closing the startup gap.

The line editor is now physical-line aware: continuation lines of a
quoted multi-line value are never mistaken for assignments, untouched
lines keep their exact bytes (CRLF included), an edited line keeps its
own terminator, and appends use the document's dominant ending. A
multi-line entry reports writable: false, matching what set() would do.

The Credentials base class owns a contained notifyUpdated fan-out:
providers publish only after the commit, every listener runs, sync throws
and async rejections are logged without failing the committed write, and
INVARIANT-coded failures rethrow after the fan-out.

Subject: [PATCH 033/102] fix(cli)!: stop hoisting $DSH_HOME/.env into
 process.env
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The shipped surfaces loaded the harness home's .env into the process
environment before cordis booted. credentials-local then saw every stored
key as an ambient launch override: describe reported source 'env' with
writable false, and set/unset rejected as shadowed — so a key the web page
or TUI stored was unrotatable and undeletable from the next run onward,
and the adapter kept using the value captured at launch.

The home's .env is now the credential provider's own store, read by that
provider alone and hot-reloaded by it. The genuine launch environment and
the invoking directory's .env (loaded by the bin) remain the read-only
ambient layer, so a plain composition without the provider still resolves
keys exactly as before.

Proven by a real restart in the loader composition: store a key through
the seam, dispose the tree, re-boot over the same harness home, and the
entry is still file-sourced and writable — rotating it lands on the very
next request.

 - resumes a persisted session with `dsh --resume <session-id>` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized `dsh --resume <id>`; runtimes without process replacement keep the displayed command fallback. The flag provides the id on the boot context under `RESUME_SESSION_ID_KEY` (no environment variable), which the shipped config reads through `!!js`, and a missing or unreadable id fails loud instead of creating a fresh session;
 - treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd;
 - tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential `cordis` toolset can read and modify it;

+- applies the personal overlay from `~/.dsh` (see [app-boot's Personal config](../../packages/ui/app-boot/README.md#personal-config)): `config.yaml` patches the booted tree, while `.env` there is the credential provider's own store (never hoisted into the environment, so keys stay rotatable). Environment precedence is ambient > project `.env`.
 
 The Web and headless surfaces boot one shared composition (`cordis.yml`): both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root <path>` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. Headless differs only in listening on an OS-assigned port (parallel `dsh -p` runs never collide; the stderr-printed URL opens the live session in a browser). Both need the frontend dist and client bundles built (`pnpm run build && pnpm run build:web`).

 A developer's machine-local preferences live outside every repository in the Harness home (default `~/.dsh`, overridable via `$DSH_HOME`; the single root [`resolveDshHome`](../../util/paths/README.md) resolves), consumed by the `dsh` CLI's TUI surface ([`apps/cli`](../../../apps/cli/README.md)); the demo bins boot their committed trees verbatim. Two optional files:
 
-- **`.env`** — loaded after the invoking directory's `.env`; `process.loadEnvFile` never overrides, so precedence is ambient environment > project `.env` > personal `.env`.
-- **`config.yaml`** — loader overlay patches applied over the shipped default config, with the same semantics as an include entry's `patches` (the committed Code Mode overlay is the template): an id-targeted patch replaces the named entry's whole `config` (restate unchanged fields), `insert` adds entries, and `!!js` expressions interpolate at mount — so a personal `apiKey` can reference the personal `.env`. A patch naming an entry id absent from the booted tree is skipped with a loader warning. An empty or comments-only file throws (it parses to nothing, not to a list); disable the overlay with `[]` or by deleting the file.
+- **`.env`** — the credential store of [`dsh-credentials-local`](../../credentials/credentials-local/README.md), read by that provider alone. No surface hoists it into `process.env`: doing so would make every stored key look like a read-only launch override on the next run, blocking rotation from the TUI and the web page. The environment layers are the ambient one and the invoking directory's `.env` (loaded by the bin; `process.loadEnvFile` never overrides), and a composition without the credential provider keeps resolving keys from those alone.

Subject: [PATCH 034/102] fix(llm): atomic route replacement, whole-snapshot
 requests, and loud credential misses
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Four review findings across the seam and both adapters.

registerAdapter now returns a handle carrying replace(providers): the
candidate route set is validated in full before anything moves, so a
route another adapter owns leaves the previous registration intact, and
the swap itself is one synchronous section with no observable gap. pi-ai
uses it instead of dispose-then-register — the old shape dropped every
route when the new set conflicted, and its facts cache could then equal
the registry's, so reverting to a working configuration never re-applied.
Its registration facts are also sorted by provider, so a settings
document that merely reorders keys no longer triggers a swap.

DeepSeek's per-request snapshot now carries the credential facts, and
resolveApiKey receives it instead of re-reading the raw config: a
settings generation the resolver rejects can no longer contribute its
literal key to a request the previous generation's endpoint serves.

pi-ai only defers to the SDK's provider-native discovery when a profile
names no credential at all; a configured apiKeyEnv that misses now fails
with MISSING_CREDENTIAL naming the route and the reference, instead of
handing pi-ai undefined and letting it authenticate with an unrelated
ambient key.

The eager boot-time credential probe is gone: it could run before the
credentials service mounted and reported every failure as a missing key.
The route stays registered and browsable; the first request gives the
accurate error, whose guidance now leads with the credential store and
mentions a literal apiKey last.

Subject: [PATCH 035/102] fix(settings): keep installSettingsSection quiet when
 its consumer unloads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The helper's cleanup ran the same fallback for two different events. A
settings provider detaching leaves the consumer running, so falling back
to the composition entry and re-judging derived facts is right. The
consumer's own unload ran it too — re-registering routes and touching
resources the teardown was releasing. The disposer now checks the
consumer fiber's own state and returns when it is unloading or disposed.

Subject: [PATCH 036/102] feat(sandbox): deny confined executions read access
 to the credential document
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The credential store is 0600 under a 0700 directory, which stops other OS
users but not the model: tool processes run as the same user, so under
the shipped danger-full-access default they read it like any other file.

SandboxExecutionPolicy grows readDenyPaths, and sandbox-policy defaults
it to $DSH_HOME/.env — the exact file rather than the harness home, so
the model keeps its documented access to its own session log. Seatbelt
appends a trailing deny (last matching rule wins) and bwrap maps
/dev/null over each path after any workspace bind; Landlock grants are a
pure allow-list that cannot subtract from its own / read grant, so
confine() reports partial enforcement there instead of claiming a
boundary the process does not have.

A real-kernel Seatbelt e2e proves the shape: the same read succeeds
unconfined and fails under the denial, while a sibling file in the same
directory stays readable. Both READMEs state the residual boundary
plainly — no confining mode means no boundary — and record the OS
keychain provider as the real answer.

 External edits publish `credentials/updated` per changed reference after the snapshot is replaced **wholesale** — an entry deleted on disk never lingers in memory. The provider's own writes are recognized by content and publish exactly their one commit event. An unreadable document at runtime keeps the last good snapshot and warns; an absent file is an empty store; an unreadable file at boot fails loud. Keys that are not POSIX identifiers are preserved file content the seam cannot address.
 
+## Security boundary
+
+The document is `0600` under a `0700` directory, which stops other OS users — **not** the model. Tool processes (bash, the filesystem tools) run as the same user, so under the shipped `danger-full-access` default they can read this file exactly like any other file the user owns. Two things narrow that:
+
+- A **confining sandbox mode** denies the credential document specifically: [`dsh-sandbox-policy`](../../sandbox/sandbox-policy/README.md) defaults `readDenyPaths` to `$DSH_HOME/.env`, and the Seatbelt and bwrap backends enforce it (Landlock cannot subtract from its own `/` read grant and reports `partial`). The denial names the file, not the home, so the model keeps its documented access to its own session log.
+- The harness never hands the model a resolved path to the document, and never loads it into the process environment (see [app-boot's Personal config](../../ui/app-boot/README.md#personal-config)).
+
+Neither makes an unconfined agent safe. A deployment that must keep provider keys away from its own agent should run a confining mode; an OS-keychain provider — a store the model's processes cannot read at all — is the deferred answer and belongs beside this provider as a sibling package.
+
 ## Model Experience
 
 Indirectly, through the consuming LLM adapters: stored values authorize their provider requests, and the adapter owns every model-visible surface.

 ## Known Limitations and Deferred Work
 
-- **Multi-line entries refuse `set`/`unset`** — the line editor will not rewrite an entry it would corrupt; edit the file directly.
+- **Multi-line entries refuse `set`/`unset`** — the line editor will not rewrite an entry it would corrupt; `describe` reports them `writable: false` and edits must go to the file directly.
+- **Same-reference concurrent writes are last-write-wins** — the writer lock and the read-modify-write keep concurrent writers from dropping each other's entries, but two writers editing one reference still resolve to the later write; there is no revision check.
+- **A same-UID process can read the document** — see [Security boundary](#security-boundary): only a confining sandbox mode denies it, and an OS-keychain provider is deferred.
 - **Unrepresentable values fail loud** — control characters, or a mix of both quote styles with backslashes, cannot round-trip the dotenv line format.
 - **Environment changes are invisible** — `process.env` is read live per resolution, but no event can announce a change there.
 - **Atomic, not crash-durable** — inherited from `dsh-atomic-write`; the store re-reads on boot.

 - `mode` — the deployment default `SandboxMode` (`read-only` / `workspace-write` / `danger-full-access`), validated at load. Default `read-only` (fail-safe).
 - `workspaceRoot` — the fallback directory `workspace-write` may write under for agentless calls or sessions without a cwd. Default `process.cwd()`, resolved to its absolute filesystem identity either way. A normal agent call uses its session header's immutable `cwd` instead.
 
+## Read denials
+
+`readDenyPaths` names absolute paths a **confined** execution must not read, whatever its mode otherwise permits. Omitted (or empty) denies the harness credential document `$DSH_HOME/.env`; a non-empty list replaces that default. Denials name exact paths rather than roots on purpose: denying the whole harness home would also take away the model's documented access to its own session log.
+
+Enforcement is backend-shaped. Seatbelt appends a trailing `deny file-read* file-write*` (last matching rule wins) and bwrap maps `/dev/null` over each path after any workspace bind; Landlock grants are a pure allow-list, so a read grant on `/` cannot be subtracted from and `confine()` reports `partial` enforcement rather than pretending the boundary exists. `danger-full-access` confines nothing at all, so no denial applies there — the credential document is then protected only by its file mode, which does not stop a same-UID tool process.
+
 ## Surface
 
 - `ctx.sandboxPolicy.resolve({ session?, mode? })` — resolves one complete per-call policy. An explicit approved mode outranks the session's last `sandbox/mode` event, which outranks `defaultMode`; the session's immutable `cwd` is canonicalized with filesystem semantics before becoming `workspaceRoot`, otherwise the configured fallback applies. Canonicalization precedes lexical normalization so `symlink/..` agrees with process working-directory resolution.

Subject: [PATCH 037/102] test(sandbox): carry the resolved read denials
 through consumer policy assertions

The policy home's resolve() now stamps readDenyPaths, so every consumer
that pins the resolved shape (bash-sandbox hand-off, tool-fs stamps)
carries it, and three uncovered branches gained real tests: landlock
reporting partial enforcement for a denial it cannot express, the
policy's default under programmatic construction, and both ambient
credential paths in llm-deepseek without a mounted seam.

The demos mount `settings-local` + `credentials-local` by default and inline no `!!js` key plumbing. `runLoaderSmoke` gained `expectedExitCode` so a designed failure surface can be pinned rather than masked. Deferred: the wire/UI surface must redact `role('secret')` fields before any RPC exposes `describe()`, settings-layer arrays still replace wholesale (the deepseek `models` list), and a settings section cannot remove a composition-provided pi-ai route (only override or extend).

+# Agent Note: credential boundaries, whole-snapshot requests, and atomic route registration
+
+Status: implemented
+
+English | [中文](2026-07-30-credential-boundaries-and-atomic-registration.zh.md)
+
+> Scope: the third review round over the [request-level LLM configuration seam](2026-07-29-request-level-llm-config-credentials.md) — where a stored credential lives and who can read it, how one request's facts stay one generation, and how a route set changes without a window. Companion to the [settings write-path note](2026-07-30-settings-write-path-integrity.md), whose provider fixes this round applies to `credentials-local` and whose writer lock it promotes into `dsh-atomic-write`.
+
+## Problem
+
+Review found the credential path leaking across boundaries it had drawn. The shipped surfaces hoisted `$DSH_HOME/.env` into `process.env` before cordis booted, so on the next run `credentials-local` classified every key it had stored itself as a read-only ambient launch override: `describe()` reported `source: 'env'` with `writable: false`, `set`/`unset` rejected as shadowed, and a key stored from the web page or TUI became unrotatable and undeletable while the adapter kept using the value captured at launch. The store's own write path repeated the settings-local defects that same review round fixed (two independent chains, whole-file render from a stale cache), plus editor bugs of its own: a physical line inside another key's quoted multi-line value read as an assignment, CRLF endings degraded to LF, a multi-line entry reported `writable: true` while `set` always threw, and `credentials/updated` was emitted bare after the commit, so one broken observer made a durable write look failed. On the read side, the file's `0600` mode stops other OS users but not the model, whose bash and filesystem tools run as the same user.
+
+Two request-path defects sat beside them. DeepSeek's per-request resolution kept connection facts in a last-good snapshot but re-read the literal `apiKey` from the raw configuration, so a settings generation the resolver rejected could still put its key on the previous generation's endpoint. pi-ai handed the SDK `undefined` when a configured `apiKeyEnv` resolved to nothing, letting pi-ai's own environment discovery authenticate with an unrelated provider key — another tenant, silently billed. And its route swap disposed the old registration before creating the new one: a route another adapter owned dropped every existing route, after which the facts cache could equal the registry's, so restoring the working configuration never re-applied.
+
+## Decision
+
+**`$DSH_HOME/.env` belongs to the credential provider alone.** No surface loads it into `process.env`. The genuine launch environment and the invoking directory's `.env` (loaded by the bin) stay the read-only ambient layer, so a composition without the provider resolves keys exactly as before, while a stored key stays file-sourced and writable across restarts — proven by a real restart in the loader composition rather than by a unit assertion about `describe()`.
+
+**The confining sandbox is the only real read boundary, and it names the file.** `SandboxExecutionPolicy` grows `readDenyPaths`, defaulted by `sandbox-policy` to `$DSH_HOME/.env`. Seatbelt appends a trailing `deny file-read* file-write*` (SBPL's last matching rule wins) and bwrap maps `/dev/null` over each path after any workspace bind; Landlock grants are a pure allow-list that cannot subtract from its own `/` read grant, so `confine()` reports `partial` enforcement instead of claiming a boundary the process lacks. Denials name exact paths, not roots: denying the whole harness home would also take away the model's documented access to its own session log. Both READMEs state the residue plainly — under the shipped `danger-full-access` default nothing is confined and the file is protected only by the OS user — and record an OS-keychain provider as the real answer.
+
+**One request, one generation.** DeepSeek's resolved snapshot carries the credential facts (literal key and reference) beside the endpoint, and `resolveApiKey` receives that snapshot instead of re-reading configuration. A rejected generation now contributes nothing at all. pi-ai defers to provider-native discovery only for a profile naming no credential; a configured reference that misses fails with `MISSING_CREDENTIAL` naming the route and the reference. The boot-time credential probe is deleted: it could run before the credentials service mounted and reported every failure as a missing key, while the first request already gives the accurate error.
+
+**Route replacement is a registry operation, not a caller sequence.** `registerAdapter` returns a handle carrying `replace(providers)`: the candidate set is validated in full first (conflicts, names, provider metadata), then swapped in one synchronous section. A refused replacement leaves the previous routes registered and serving, and the caller's facts cache only advances after the registry actually holds the new set, so reverting to a working configuration re-applies. pi-ai's registration facts are sorted by provider, so a settings document that merely reorders its keys is no longer a route change.
+
+**Contained publication for committed credential writes.** `Credentials.notifyUpdated` fans `credentials/updated` out one listener at a time; sync throws and async rejections are logged without changing the committed operation's outcome, and `INVARIANT`-coded failures rethrow after every listener ran — the same shape the settings seam uses for `settings/updated`. `installSettingsSection`'s cleanup now distinguishes its two triggers: a provider detaching still falls back to the composition entry and re-derives, while the consumer's own unload returns immediately instead of re-registering routes during teardown.
+
+## Alternatives considered
+
+- **Denying the whole harness home** — one root would have covered the credential document and any future secret file, but it also covers `sessions/`, and `DSH_SESSION_JSONL` is a documented model-visible capability. Exact paths keep the denial to what is actually secret.
+- **Removing `DSH_HOME` from the model's bash environment** — considered as defense in depth and rejected as theater with a real cost: the default home is a documented convention the agent can reconstruct, while the variable is how legitimate tooling finds harness state. The sandbox denial is the boundary; hiding the pointer is not.
+- **Shipping the OS-keychain provider in this round** — it is the only design where the model's processes genuinely cannot read the secret, and it is a sibling package with three platform backends. Sizing it against the rest of this review round would have delayed every other fix; it is recorded as the deferred answer, not as a maybe.
+- **Treating `readDenyPaths: []` as an opt-out** — schemastery fills an omitted array with `[]`, so empty and omitted are indistinguishable at the constructor. Empty therefore means "protect the default document"; a deployment that stores credentials elsewhere names its own paths, and a denial on a path nothing reads costs nothing.
+- **A `replaceRegistration(previous, next)` service method** — the review's shape, but it makes the caller carry the previous handle and lets it pass a mismatched one. Hanging `replace` on the registration handle makes ownership structural: only the registration that holds routes can replace them.
+
+## Consequences
+
+`update()`-adjacent behavior gained documented failure modes: a credential write can now fail on the lock deadline or on an unparsable on-disk document, and `describe()` reports `writable: false` for multi-line entries it will not rewrite. A confined execution loses read access to `$DSH_HOME/.env` — deployments that deliberately let an agent read its own credential file must configure `readDenyPaths` themselves. `LlmAdapter` registrants keep working unchanged (the handle is still callable as the disposer), and `DeepSeekConnectionOptions` gained credential fields, so a programmatic constructor of the adapter must supply `apiKeyEnv`. Deferred: the OS-keychain credential provider, and per-value revision checks for two writers editing one reference (last-write-wins remains the documented resolution).

 Connection facts are not frozen at load. `resolveAdapterOptions` is the one explicit resolve step from raw config to validated facts, and the adapter re-reads them through a thunk **once per operation**: base URL, catalog, request defaults, and idle budget all take effect on the next request, while an in-flight stream keeps the facts it started with. Two optional seams feed that thunk:
 
 - **`ctx.settings`** — the plugin registers the `llm-deepseek` namespace with this same `Config` schema and its `cordis.yml` entry as the composition `base`, so a `llm-deepseek:` section in the user settings document overrides any field without a restart. Without a mounted settings service the entry config alone drives the adapter, unchanged. A live settings snapshot that passes the schema but fails a beyond-schema bound (a duplicate catalog id, a broken thinking/effort pair) keeps the last good facts and logs the failure; the entry config itself still fails plugin load.
-- **`ctx.credentials`** — the API key resolves per stream call: a non-empty literal `apiKey` wins, then `apiKeyEnv` through the credential seam (`$DSH_HOME/.env` under the live environment), then — only without a mounted seam — the raw environment variable. A request with no key anywhere fails with `MISSING_CREDENTIAL` naming every configuration entry point, while the route stays registered and the catalog stays browsable — first-run onboarding is "browse models, store the key, prompt again", with no restart between.
+- **`ctx.credentials`** — the API key resolves per stream call, from the *same* resolved snapshot that supplies the endpoint: a non-empty literal `apiKey` wins, then `apiKeyEnv` through the credential seam (`$DSH_HOME/.env` under the live environment), then — only without a mounted seam — the raw environment variable. Because credential facts travel with the connection facts, a settings snapshot the resolver rejects contributes neither its endpoint nor its key: the whole previous generation keeps serving. A request with no key anywhere fails with `MISSING_CREDENTIAL` naming every configuration entry point, while the route stays registered and the catalog stays browsable — first-run onboarding is "browse models, store the key, prompt again", with no restart between.
 
 The one registration-captured fact is the retry policy: when its resolved value changes, the plugin re-registers the route in place (same adapter instance, one synchronous section), so `ctx.llm.providerRetryPolicy('deepseek')` always reports the current policy.

The returned disposer also carries `replace(providers)`: the candidate route set is validated in full before anything moves, so a conflict with another adapter leaves the current routes registered and serving, and the swap itself is one synchronous section with no observable gap. `replace([])` is legal — a registration holding zero routes — unlike an empty initial registration.

Subject: [PATCH 038/102] docs(credentials): record the third-review contracts
 across READMEs, catalogs, and a new Agent Note

Both provider READMEs state what actually holds: credentials-local now
documents the physical-line editor, the read-modify-write under the
writer lock, and a Security boundary section saying plainly that the file
mode stops other OS users and not the model. sandbox-policy documents
readDenyPaths and its per-backend enforcement. The llm READMEs carry the
registration handle, pi-ai's credential-miss semantics, and DeepSeek's
same-generation snapshot; app-boot and the CLI README stop describing
$DSH_HOME/.env as an environment layer.

A new Agent Note records the round (and the prior seam note cross-links
it); the sandbox and core catalog pages gain readDenyPaths and
AdapterRegistrationHandle with their manifest entries. The headless
missing-credential snapshot re-records for the reworded guidance, pi-ai
gains the Loader-composition guard its twin already had, and the
deliberate provider symmetry is marked for the clone detector.

+# Agent Note: 凭据边界、按整份快照发起的请求与原子路由注册
+
+Status: implemented
+
+[English](2026-07-30-credential-boundaries-and-atomic-registration.md) | 中文
+
+> 范围：对[请求级 LLM（大语言模型）配置 seam](2026-07-29-request-level-llm-config-credentials.md)的第三轮评审——存下来的凭据落在哪里、谁能读到它，一次请求的事实如何保持为同一代，以及一组路由如何在不留空窗的前提下更换。本 note 与 [settings 写路径 note](2026-07-30-settings-write-path-integrity.md) 配套：本轮把那篇 note 的提供方修复套用到 `credentials-local`，并把其中的写锁提升进 `dsh-atomic-write`。
+
+## 问题
+
+评审发现，凭据路径正在越过它自己划下的边界泄漏。已交付的各个面在 Cordis 启动之前就把 `$DSH_HOME/.env` 提升进了 `process.env`，于是下一次运行时，`credentials-local` 会把它自己存下的每个键都判成来自环境的只读启动覆盖：`describe()` 报告 `source: 'env'` 且 `writable: false`，`set`/`unset` 以被遮蔽为由拒绝，从 web 页面或 TUI 存入的密钥既无法轮换也无法删除，而适配器还在继续使用启动时捕获的那个值。
+
+存储自身的写路径重演了同一轮评审在 settings-local 修掉的那些缺陷（两条相互独立的链、从陈旧缓存渲染整份文件），还叠加了编辑器自己的缺陷：另一个键的带引号多行值内部的一条物理行会被读成赋值，CRLF 行尾会退化成 LF，多行条目报告 `writable: true` 而 `set` 总是抛错，`credentials/updated` 又在提交之后裸发，于是一个出错的观察者就能让一次已经落盘的写入看起来失败。
+
+在读取一侧，文件的 `0600` 权限挡得住其他 OS 用户，却挡不住模型：它的 bash 与文件系统工具就以同一个用户身份运行。
+
+与之并排的还有两个请求路径缺陷。DeepSeek 的按请求解析把连接事实保存在最后可用快照里，却仍从原始配置重新读取字面 `apiKey`，于是被 resolver 拒绝的那一代设置，照样能把自己的密钥送到上一代的端点上。配置了 `apiKeyEnv` 却解析不到值时，pi-ai 会把 `undefined` 交给 SDK，让 pi-ai 自己的环境发现拿一个毫不相干的提供方密钥完成鉴权——那是另一个租户，账单还悄悄记在它头上。而且它的路由替换是先释放旧注册、再创建新注册：只要有一条路由已被别的适配器占有，现有路由就会被全部丢掉，此后事实缓存可能与注册表中的事实相等，于是把配置改回可用状态也不会重新生效。
+
+## 决策
+
+**`$DSH_HOME/.env` 只归凭据提供方所有。**没有任何一个面会把它加载进 `process.env`。真正的启动环境，以及调用目录中由 bin 加载的 `.env`，仍然是那一层只读的环境来源，因此不挂载该提供方的组合，解析密钥的方式与从前完全一致，而存下的密钥跨重启仍然来源于文件、仍然可写——这一点由 Loader 组合中的一次真实重启来证明，而不是靠对 `describe()` 的单元断言。
+
+**受限沙箱才是唯一真正的读取边界，而且它点名到具体文件。**`SandboxExecutionPolicy` 新增 `readDenyPaths`，由 `sandbox-policy` 默认设为 `$DSH_HOME/.env`。Seatbelt 在末尾追加一条 `deny file-read* file-write*`（SBPL 中最后一条匹配规则胜出），bwrap 则在所有工作区 bind 之后把 `/dev/null` 映射到每条路径上；Landlock 的授权是纯粹的允许列表，无法从它自己对 `/` 的读取授权中减去任何东西，因此 `confine()` 报告 `partial` 强制执行，而不是声称一条该进程其实并不具备的边界。拒绝点名的是确切路径，而不是根目录：把整个 harness home 都拒掉，会连带夺走模型对自身会话日志的成文访问权。两个 README 都直白写明残留风险——在已交付的 `danger-full-access` 默认值下没有任何东西受限，这个文件只靠 OS 用户身份保护——并记下 OS 钥匙串（keychain）提供方才是真正的答案。
+
+**一次请求，一代设置。**DeepSeek 解析出的快照在端点旁一并携带凭据事实（字面密钥与引用），`resolveApiKey` 接收这份快照，而不再重新读取配置。被拒绝的那一代如今完全不再贡献任何东西。只有当一个 profile 完全没有点名凭据时，pi-ai 才交给提供方原生的发现流程；配置了引用却解析不到，就以 `MISSING_CREDENTIAL` 失败，并点名该路由与该引用。启动时的凭据探测被删除：它可能在凭据服务挂载之前就运行，并把每一种失败都报成密钥缺失，而第一次请求本就会给出准确的错误。
+
+**路由替换是注册表的操作，不是调用方的一串步骤。**`registerAdapter` 返回一个携带 `replace(providers)` 的句柄：候选集合先被完整校验（冲突、名称、提供方元数据），再在一个同步区段内完成替换。被拒绝的替换会让先前的路由保持注册并继续服务，而调用方的事实缓存只有在注册表确实持有新集合之后才会推进，因此改回可用配置时会重新生效。pi-ai 的注册事实按提供方排序，因此仅仅调换键顺序的设置文档不再算作路由变更。
+
+**已提交的凭据写入采用收容式发布。**`Credentials.notifyUpdated` 逐个监听器扇出 `credentials/updated`；同步抛错与异步 rejection 都只记日志，不改变已提交操作的结果，而带 `INVARIANT` 代码的失败会在每个监听器都运行完之后重抛——与 settings seam 处理 `settings/updated` 的形状相同。`installSettingsSection` 的清理现在会区分它的两个触发来源：提供方脱离时仍回退到组合的 entry 配置并重新推导，而消费方自身卸载时立即返回，不再在拆卸过程中重新注册路由。
+
+## 曾考虑的替代方案
+
+- **拒掉整个 harness home**——一个根目录本可覆盖凭据文档以及将来任何机密文件，但它同时也覆盖 `sessions/`，而 `DSH_SESSION_JSONL` 是一项成文的、模型可见的能力。用确切路径可以把拒绝范围限定在真正属于机密的东西上。
+- **把 `DSH_HOME` 从模型的 bash 环境中移除**——作为纵深防御考虑过，最终按「有真实代价的表演」不予采纳：默认 home 是 agent（智能体）能自行重建的成文约定，而这个变量正是正当工具链定位 harness 状态的途径。沙箱拒绝才是边界，藏起指针不是。
+- **本轮就交付 OS 钥匙串提供方**——只有这个设计能让模型的进程真正读不到机密，而它是一个带三种平台后端的兄弟包（package）。把它与本轮评审的其余工作放在一起评估体量，会拖慢其他每一项修复；它被记录为那个延后的答案，而不是一个「也许」。
+- **把 `readDenyPaths: []` 当作 opt-out**——schemastery 会把省略的数组填成 `[]`，因此在构造函数处空数组与省略无从分辨。于是空数组的含义就是「保护默认文档」；把凭据存在别处的部署自行点名它自己的路径，而在没人读取的路径上设一条拒绝并不产生任何代价。
+- **做成 `replaceRegistration(previous, next)` 服务方法**——这是评审给出的形状，但它要求调用方自行携带上一个句柄，也允许它传入一个不匹配的句柄。把 `replace` 挂在注册句柄上，让归属关系变成结构性的：只有持有路由的那一项注册才能替换它们。
+
+## 后果
+
+`update()` 邻近的行为多了成文的失败模式：凭据写入现在可能因锁截止时间到期、或磁盘文档无法解析而失败，`describe()` 对它不会改写的多行条目报告 `writable: false`。受限执行会失去对 `$DSH_HOME/.env` 的读取权限——刻意让 agent 读取自身凭据文件的部署，必须自行配置 `readDenyPaths`。`LlmAdapter` 的注册方无需改动即可继续工作（句柄本身仍可当作释放器调用），`DeepSeekConnectionOptions` 则新增了凭据字段，因此以编程方式构造该适配器必须提供 `apiKeyEnv`。延后事项：OS 钥匙串凭据提供方，以及针对两个写方编辑同一引用的逐值修订号检查（后写胜出仍是成文的解决方式）。

 Web 和无头界面启动同一个共享组合（`cordis.yml`）：两者都将调用目录视为默认项目和 Workspace 根目录，除非通过 `--workspace-root <path>` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，并选用首条消息模型标题。无头界面唯一的差异是监听操作系统分配的端口（并行 `dsh -p` 运行绝不冲突；stderr 打印的 URL 会在浏览器中打开实时会话）。两者都需要先构建前端 dist 和客户端 bundle（`pnpm run build && pnpm run build:web`）。

Subject: [PATCH 039/102] refactor(ui-models): render the curated fields from a
 narrowed adapter family
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The effort field's existence check was unreachable — EFFORT_FIELD is
total over the two known families — and a coverage exemption was papering
over the branch, which the merged toolchain no longer honored. Taking the
narrowed family as a parameter makes the lookup total at the type level,
so the check and its exemption both disappear. The rendered output is
unchanged: the browser goldens replay byte-identical.

Subject: [PATCH 041/102] feat(web): add a web render-intent card for
 web_search and web_fetch results

web_search and web_fetch returned only model-facing text, whose markdown source
list is lossy (title-or-hostname label, snippet and date concatenated), so a
client could not recover the structured sources. Add a card:'web' result view
with a kind discriminant ('search' carrying structured sources + answer +
truncated, 'fetch' carrying url + statusCode + truncated), projected through
each tool's output.presentationMeta and read back in presentResult. A UI
without the web card falls back to content; the TUI is unchanged. The web
consumer is a follow-up.

+# Agent Note: Web result card — a structured render intent for web_search and web_fetch
+
+Status: implemented
+
+English | [中文](2026-07-30-web-result-card.zh.md)
+
+## Problem
+
+The `web_search` and `web_fetch` tools each declared a generic pending card (`presentCall`, `kind: 'search'`/`'fetch'`) but no `presentResult`, so a completed web call reached a UI only as the model-facing render text. For a web frontend that wants to render a citation list or a fetch summary, that text is lossy: `web_search`'s render collapses each source's `title`, `snippet`, and `publishedAt` into one free-text markdown line labelled by title OR hostname (`formatSearchOutput` in `packages/web/tool-web/src/search.ts`), so reparsing the render cannot recover the per-source fields; and `web_fetch`'s render carries `url` and `statusCode` only in a header line. The render-intent contract ([tagged union](../architecture/2026-07-02-tool-render-intent-union.md)) had no arm a web tool could declare to carry a structured result.

+Add one `card: 'web'` result arm to `ToolResultView` (`packages/core/tools/src/presentation.ts`), a union `WebResultView = WebSearchResultView | WebFetchResultView` discriminated by a `kind: 'search' | 'fetch'` field, plus a `WebSource` shape for one citeable source. Both tools now declare `presentResult`.
+
+One tag with a `kind` discriminant, not two tags. Both calls are web retrieval and a web frontend renders them with one component family (a retrieval card whose body differs by kind), so a shared `card` keeps every card consumer's switch to one added arm and lets the frontend branch on `kind` inside it. Two tags would force every present and future consumer to add two arms for what is one visual family. The `kind` values match the two tools' existing generic call-view `kind`s, so a call and its result read as the same category.
+
+`presentationMeta` is mandatory here, not a convenience. The structured result object a tool returns from `execute` does NOT reach a client over the wire — only the model-facing `render` text and, when declared, the `output.presentationMeta` JSON projected onto the `tool/result` event's `meta` do. Because the render text is lossy for `web_search`'s sources, projecting the sources through `presentationMeta` is the only faithful route to `{url, title?, snippet?, publishedAt?}` at the consumer. This mirrors the write/edit diff template (`packages/fs/tool-fs/src/diff.ts`): a `*MetaFromValue` projector feeds `output.presentationMeta`, and a `*MetaFromResult` narrower reads `result.meta` back with a defensive fallback to the generic card. `web_fetch`'s meta carries `url`/`statusCode`/`truncated` only; its body is already markdown in the result content, so it is not duplicated into meta.
+
+Each result view carries an optional `content?: ContentBlock[]` set to the model-facing result content. A UI without the `web` capability — including the TUI, whose transcript renderer has no `web` arm — renders that content through its existing generic/default path (`packages/ui/tui/src/components/transcript.ts`, `renderBody`'s `view.content ?? this.result?.content`), so the new tag needs no dedicated TUI arm and the TUI keeps compiling and rendering the text.
+
+`presentResult` returns `undefined` (the generic card) on an error result and on absent or malformed `meta`, because presentation runs on replay of arbitrary logged results (possibly from an older schema) and must never throw. The narrowers validate every field defensively; an empty source list is valid meta, not malformed.
+
+## Consequences
+
+The web frontend consumer is a separate later PR: this PR adds the contract arm and makes the two tools emit it, with no client-side rendering. Any existing `ToolResultView` consumer that switches exhaustively must add a `web` arm; the TUI does not switch exhaustively and needs none. `apiproxy`'s session schema already accepts any `card` string (`packages/host/apiproxy/src/api/sessions.schema.ts`), so the new view crosses the wire without a schema change.
+
+A future web tool that wants this card declares `presentResult` returning a `card: 'web'` view with its own `kind`; adding a third `kind` is a union edit plus the frontend's branch, not a new card tag.
+
+## Alternatives considered
+
+**Two card tags (`web-search`, `web-fetch`).** Rejected: it doubles the arm count at every card consumer for one visual family, and the two shapes already share enough (a titled retrieval card with fallback content) that a `kind` discriminant expresses the difference without a second tag.
+
+**Reparse the render text in `presentResult` instead of projecting meta.** Rejected for `web_search`: the render's source list is lossy (title-or-hostname label, snippet and date concatenated into free text), so reparsing cannot faithfully recover the structured fields. `presentationMeta` is the only route that preserves them.
+
+**Carry the fetch body in meta too.** Rejected: the body is already the model-facing markdown in the result content, and duplicating it into meta would double the persisted payload for no gain; the view points a UI at the existing content.
+
+## Testing
+
+`packages/web/tool-web/tests/tool-web.spec.ts` covers, per-file to the 100% gate: `searchMetaFromValue`/`fetchMetaFromValue` projection including omission of absent optional fields; `searchMetaFromResult`/`fetchMetaFromResult` narrowing with a round-trip and every malformed-shape rejection (non-object, wrong field types, a malformed source entry) plus the empty-source-list accept; `presentSearchResult`/`presentFetchResult` typed views including the truncated signal, the error-result fallback, and the malformed-meta fallback; and two real-registry executions asserting the tool projects the meta onto `result.meta` and its registered `presentResult` derives the `card: 'web'` view.

+# Agent Note: Web result card — a structured render intent for web_search and web_fetch
+
+Status: implemented
+
+[English](2026-07-30-web-result-card.md) | 中文
+
+## Problem
+
+`web_search` 与 `web_fetch` 工具各自声明了一个 generic 待定卡片（`presentCall`，`kind: 'search'`/`'fetch'`），但没有 `presentResult`，因此一个已完成的 web 调用抵达 UI 时只剩下面向模型的 render 文本。对于想渲染引用列表或抓取摘要的 web 前端而言，该文本是有损的：`web_search` 的 render 把每个来源的 `title`、`snippet`、`publishedAt` 压进一行以 title 或 hostname 标注的自由文本 markdown（`packages/web/tool-web/src/search.ts` 中的 `formatSearchOutput`），因此重新解析 render 无法恢复各来源字段；`web_fetch` 的 render 也仅在一行 header 里携带 `url` 与 `statusCode`。渲染意图契约（[标签联合类型](../architecture/2026-07-02-tool-render-intent-union.md)）此前没有一个可供 web 工具声明、用以携带结构化结果的分支。
+
+## Decision
+
+向 `ToolResultView`（`packages/core/tools/src/presentation.ts`）新增一个 `card: 'web'` 结果分支，它是以 `kind: 'search' | 'fetch'` 字段作判别的联合 `WebResultView = WebSearchResultView | WebFetchResultView`，并附一个表示单个可引用来源的 `WebSource` 形状。两个工具现在都声明 `presentResult`。
+
+采用一个标签加 `kind` 判别，而非两个标签。两个调用都是 web 检索，web 前端会用同一族组件渲染它们（一个检索卡片，正文按 kind 不同），因此共用一个 `card` 让每个 card 消费者的 switch 只需新增一个分支，并让前端在其内部按 `kind` 分岔。两个标签会迫使当前及未来每个消费者为本属同一视觉族的东西添加两个分支。这两个 `kind` 取值与两个工具既有的 generic 调用视图 `kind` 一致，因此一个调用与它的结果读起来是同一类别。
+
+`presentationMeta` 在这里是必需的，而非便利手段。工具从 `execute` 返回的结构化结果对象**不会**经由 wire 抵达客户端——只有面向模型的 `render` 文本，以及（声明时）投影到 `tool/result` 事件 `meta` 上的 `output.presentationMeta` JSON 会。由于 render 文本对 `web_search` 的来源是有损的，经 `presentationMeta` 投影来源，是在消费端得到忠实 `{url, title?, snippet?, publishedAt?}` 的唯一途径。这照搬 write/edit 的 diff 模板（`packages/fs/tool-fs/src/diff.ts`）：一个 `*MetaFromValue` 投影器喂给 `output.presentationMeta`，一个 `*MetaFromResult` 收窄器读回 `result.meta`，并在失败时防御性回退到 generic 卡片。`web_fetch` 的 meta 只携带 `url`/`statusCode`/`truncated`；其正文已是结果内容中的 markdown，因此不重复写入 meta。
+
+每个结果视图携带一个可选的 `content?: ContentBlock[]`，设为面向模型的结果内容。不具备 `web` 能力的 UI——包括其 transcript 渲染器没有 `web` 分支的 TUI——经由既有的 generic/默认路径渲染该内容（`packages/ui/tui/src/components/transcript.ts` 中 `renderBody` 的 `view.content ?? this.result?.content`），因此新标签无需专门的 TUI 分支，TUI 继续编译并渲染文本。
+
+`presentResult` 在错误结果、以及 `meta` 缺失或畸形时返回 `undefined`（即 generic 卡片），因为 presentation 会在对任意已记录结果（可能来自旧 schema）的重放中运行，绝不能抛错。收窄器防御性地校验每个字段；空来源列表是有效 meta，而非畸形。
+
+## Consequences
+
+web 前端消费者是一个独立的后续 PR：本 PR 新增契约分支并让两个工具发出它，不含客户端渲染。任何做穷尽 switch 的现有 `ToolResultView` 消费者都必须新增一个 `web` 分支；TUI 并不穷尽 switch，无需新增。`apiproxy` 的会话 schema 已接受任意 `card` 字符串（`packages/host/apiproxy/src/api/sessions.schema.ts`），因此新视图无需 schema 变更即可跨 wire。
+
+未来想用此卡片的 web 工具，声明一个返回带自有 `kind` 的 `card: 'web'` 视图的 `presentResult`；新增第三个 `kind` 是一次联合类型编辑加前端的分岔，而非一个新的 card 标签。
+
+## Alternatives considered
+
+**两个 card 标签（`web-search`、`web-fetch`）。** 否决：它在每个 card 消费者处为一个视觉族翻倍分支数，而两个形状已共享得够多（一个带回退内容的带标题检索卡片），`kind` 判别无需第二个标签即可表达差异。
+
+**在 `presentResult` 里重新解析 render 文本，而非投影 meta。** 对 `web_search` 否决：render 的来源列表是有损的（title 或 hostname 标签，snippet 与日期拼进自由文本），因此重新解析无法忠实恢复结构化字段。`presentationMeta` 是唯一保留它们的途径。
+
+**把抓取正文也放进 meta。** 否决：正文已是结果内容中面向模型的 markdown，把它复制进 meta 会为无收益的目的翻倍持久化载荷；视图让 UI 指向既有内容。
+
+## Testing
+
+`packages/web/tool-web/tests/tool-web.spec.ts` 覆盖以下内容，满足按文件 100% 的门禁：`searchMetaFromValue`/`fetchMetaFromValue` 投影，含对缺席可选字段的省略；`searchMetaFromResult`/`fetchMetaFromResult` 收窄，含一次往返与每种畸形形状的拒绝（非对象、字段类型错误、畸形来源条目）以及空来源列表的接受；`presentSearchResult`/`presentFetchResult` 类型化视图，含 truncated 信号、错误结果回退与畸形 meta 回退；以及两次真实注册表执行，断言工具把 meta 投影到 `result.meta` 上，其注册的 `presentResult` 推导出 `card: 'web'` 视图。

Subject: [PATCH 042/102] test(tui): pin the personal overlay to the
 environment layers the CLI loads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The personal-config smoke asserted that `$DSH_HOME/.env` feeds a `!!js`
expression in the personal `config.yaml` — the hoist this branch removed so
`credentials-local` can own that document and keep stored keys rotatable.

Seed both layers instead and let one expression separate them: the welcome
prefers the personal variable, so it can only render the invoking directory's
value while the harness home's `.env` stays out of `process.env`. The negative
that made the removal worth doing is now asserted in the assembled
application, not just in the provider's unit tests.

Subject: [PATCH 043/102] revert(sandbox): withdraw the credential-document
 read denial
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The `readDenyPaths` policy field shipped in the previous commit broke Linux
confinement outright. bwrap has to create the `/dev/null` bind's mount point
inside a tree its own profile has already made read-only, so it refused the
entire confinement whenever the parent directory was absent — every host that
has not stored a credential yet, including a fresh install:

  bwrap: Can't mkdir parents for /home/runner/.dsh/.env: Read-only file system

which the executor correctly classifies as SANDBOX_UNAVAILABLE, so every
confined bash call failed closed. Landlock cannot subtract from its own `/`
read grant, so it reported `partial` enforcement on every confined call for a
file it never hid, with no way to switch the denial off (schemastery fills an
omitted array with `[]`, so empty and omitted were indistinguishable).

A protection that breaks confinement where it works and misreports it where it
does not is worse than a documented absence. Revert the field, both expressible
backends, the enforcement downgrade, and the policy default; state the residue
plainly in the credentials-local READMEs — file mode stops other OS users, not
the model — and keep the OS-keychain provider recorded as the real answer.

The narrower discipline stands: no surface hoists the credential document into
`process.env`, and the model is never handed a resolved path to it.

 **`$DSH_HOME/.env` belongs to the credential provider alone.** No surface loads it into `process.env`. The genuine launch environment and the invoking directory's `.env` (loaded by the bin) stay the read-only ambient layer, so a composition without the provider resolves keys exactly as before, while a stored key stays file-sourced and writable across restarts — proven by a real restart in the loader composition rather than by a unit assertion about `describe()`.
 
-**The confining sandbox is the only real read boundary, and it names the file.** `SandboxExecutionPolicy` grows `readDenyPaths`, defaulted by `sandbox-policy` to `$DSH_HOME/.env`. Seatbelt appends a trailing `deny file-read* file-write*` (SBPL's last matching rule wins) and bwrap maps `/dev/null` over each path after any workspace bind; Landlock grants are a pure allow-list that cannot subtract from its own `/` read grant, so `confine()` reports `partial` enforcement instead of claiming a boundary the process lacks. Denials name exact paths, not roots: denying the whole harness home would also take away the model's documented access to its own session log. Both READMEs state the residue plainly — under the shipped `danger-full-access` default nothing is confined and the file is protected only by the OS user — and record an OS-keychain provider as the real answer.
+**The stored credential has no boundary against the model, and the READMEs say so.** `0600` under a `0700` directory stops other OS users; the model's bash and filesystem tools run as that same user, and the shipped default confines nothing. What the harness does hold to is narrower and stated as exactly that: no surface hoists the document into `process.env`, and the model is never handed a resolved path to it, so reaching the value takes a deliberate read of a path it was not given. An OS-keychain provider — a store the model's processes cannot read at all — is recorded as the real answer rather than implied by a partial one.
 
 **One request, one generation.** DeepSeek's resolved snapshot carries the credential facts (literal key and reference) beside the endpoint, and `resolveApiKey` receives that snapshot instead of re-reading configuration. A rejected generation now contributes nothing at all. pi-ai defers to provider-native discovery only for a profile naming no credential; a configured reference that misses fails with `MISSING_CREDENTIAL` naming the route and the reference. The boot-time credential probe is deleted: it could run before the credentials service mounted and reported every failure as a missing key, while the first request already gives the accurate error.

 ## Alternatives considered
 
-- **Denying the whole harness home** — one root would have covered the credential document and any future secret file, but it also covers `sessions/`, and `DSH_SESSION_JSONL` is a documented model-visible capability. Exact paths keep the denial to what is actually secret.
-- **Removing `DSH_HOME` from the model's bash environment** — considered as defense in depth and rejected as theater with a real cost: the default home is a documented convention the agent can reconstruct, while the variable is how legitimate tooling finds harness state. The sandbox denial is the boundary; hiding the pointer is not.
+- **A sandbox read-denial naming `$DSH_HOME/.env`** — implemented as a `readDenyPaths` policy field (a trailing SBPL `deny file-read* file-write*`, a `/dev/null` bwrap bind) and withdrawn on its own evidence. bwrap must create that bind's mount point inside a tree its profile has already made read-only, so it refuses the entire confinement whenever the parent directory is absent — every host that has not stored a credential yet, including a fresh install; Landlock cannot subtract from its own `/` read grant, so every confined call would report `partial` for a file it never hid. A protection that breaks confinement where it works and misreports it where it does not is worse than a documented absence. Denying the whole harness home was rejected earlier for a separate reason: it also covers `sessions/`, and `DSH_SESSION_JSONL` is a documented model-visible capability.
+- **Removing `DSH_HOME` from the model's bash environment** — considered as defense in depth and rejected as theater with a real cost: the default home is a documented convention the agent can reconstruct, while the variable is how legitimate tooling finds harness state. There is no boundary here for it to complement; hiding the pointer would only make the absence harder to see.
 - **Shipping the OS-keychain provider in this round** — it is the only design where the model's processes genuinely cannot read the secret, and it is a sibling package with three platform backends. Sizing it against the rest of this review round would have delayed every other fix; it is recorded as the deferred answer, not as a maybe.
-- **Treating `readDenyPaths: []` as an opt-out** — schemastery fills an omitted array with `[]`, so empty and omitted are indistinguishable at the constructor. Empty therefore means "protect the default document"; a deployment that stores credentials elsewhere names its own paths, and a denial on a path nothing reads costs nothing.
 - **A `replaceRegistration(previous, next)` service method** — the review's shape, but it makes the caller carry the previous handle and lets it pass a mismatched one. Hanging `replace` on the registration handle makes ownership structural: only the registration that holds routes can replace them.
 
 ## Consequences
 
-`update()`-adjacent behavior gained documented failure modes: a credential write can now fail on the lock deadline or on an unparsable on-disk document, and `describe()` reports `writable: false` for multi-line entries it will not rewrite. A confined execution loses read access to `$DSH_HOME/.env` — deployments that deliberately let an agent read its own credential file must configure `readDenyPaths` themselves. `LlmAdapter` registrants keep working unchanged (the handle is still callable as the disposer), and `DeepSeekConnectionOptions` gained credential fields, so a programmatic constructor of the adapter must supply `apiKeyEnv`. Deferred: the OS-keychain credential provider, and per-value revision checks for two writers editing one reference (last-write-wins remains the documented resolution).

 ## 曾考虑的替代方案
 
-- **拒掉整个 harness home**——一个根目录本可覆盖凭据文档以及将来任何机密文件，但它同时也覆盖 `sessions/`，而 `DSH_SESSION_JSONL` 是一项成文的、模型可见的能力。用确切路径可以把拒绝范围限定在真正属于机密的东西上。
-- **把 `DSH_HOME` 从模型的 bash 环境中移除**——作为纵深防御考虑过，最终按「有真实代价的表演」不予采纳：默认 home 是 agent（智能体）能自行重建的成文约定，而这个变量正是正当工具链定位 harness 状态的途径。沙箱拒绝才是边界，藏起指针不是。
+- **用沙箱点名拒读 `$DSH_HOME/.env`**——已按 `readDenyPaths` 策略字段实现过（末尾一条 SBPL `deny file-read* file-write*`、一条 `/dev/null` 的 bwrap bind），又被它自己的证据推翻。bwrap 必须在自己 profile 已经置为只读的目录树内部创建该 bind 的挂载点，因此只要父目录不存在，它就会拒绝整次约束——那是每一台还没有存过凭据的主机，包括全新安装；Landlock 无法从它自己对 `/` 的读取授权中减去任何东西，于是每一次受限调用都会为一个它其实从未藏起的文件报 `partial`。一项在生效之处破坏约束、在不生效之处误报的保护，比一条写明的「没有保护」更糟。至于拒掉整个 harness home，早先另有理由被否：它同时覆盖 `sessions/`，而 `DSH_SESSION_JSONL` 是一项成文的、模型可见的能力。

 - **本轮就交付 OS 钥匙串提供方**——只有这个设计能让模型的进程真正读不到机密，而它是一个带三种平台后端的兄弟包（package）。把它与本轮评审的其余工作放在一起评估体量，会拖慢其他每一项修复；它被记录为那个延后的答案，而不是一个「也许」。
-- **把 `readDenyPaths: []` 当作 opt-out**——schemastery 会把省略的数组填成 `[]`，因此在构造函数处空数组与省略无从分辨。于是空数组的含义就是「保护默认文档」；把凭据存在别处的部署自行点名它自己的路径，而在没人读取的路径上设一条拒绝并不产生任何代价。
 - **做成 `replaceRegistration(previous, next)` 服务方法**——这是评审给出的形状，但它要求调用方自行携带上一个句柄，也允许它传入一个不匹配的句柄。把 `replace` 挂在注册句柄上，让归属关系变成结构性的：只有持有路由的那一项注册才能替换它们。
 
 ## 后果
 
-`update()` 邻近的行为多了成文的失败模式：凭据写入现在可能因锁截止时间到期、或磁盘文档无法解析而失败，`describe()` 对它不会改写的多行条目报告 `writable: false`。受限执行会失去对 `$DSH_HOME/.env` 的读取权限——刻意让 agent 读取自身凭据文件的部署，必须自行配置 `readDenyPaths`。`LlmAdapter` 的注册方无需改动即可继续工作（句柄本身仍可当作释放器调用），`DeepSeekConnectionOptions` 则新增了凭据字段，因此以编程方式构造该适配器必须提供 `apiKeyEnv`。延后事项：OS 钥匙串凭据提供方，以及针对两个写方编辑同一引用的逐值修订号检查（后写胜出仍是成文的解决方式）。

Tool processes (bash, the filesystem tools) run as the same user, so under the shipped `danger-full-access` default they can read this file exactly like any other file the user owns, and no sandbox mode singles it out. What the harness does hold to is narrower: it never hands the model a resolved path to the document, and never loads it into the process environment (see [app-boot's Personal config](../../ui/app-boot/README.md#personal-config)), so reaching the value takes a deliberate read of a path the agent was not given.
 
-- A **confining sandbox mode** denies the credential document specifically: [`dsh-sandbox-policy`](../../sandbox/sandbox-policy/README.md) defaults `readDenyPaths` to `$DSH_HOME/.env`, and the Seatbelt and bwrap backends enforce it (Landlock cannot subtract from its own `/` read grant and reports `partial`). The denial names the file, not the home, so the model keeps its documented access to its own session log.

 - `mode` — the deployment default `SandboxMode` (`read-only` / `workspace-write` / `danger-full-access`), validated at load. Default `read-only` (fail-safe).
 - `workspaceRoot` — the fallback directory `workspace-write` may write under for agentless calls or sessions without a cwd. Default `process.cwd()`, resolved to its absolute filesystem identity either way. A normal agent call uses its session header's immutable `cwd` instead.
 
-## Read denials
-
-`readDenyPaths` names absolute paths a **confined** execution must not read, whatever its mode otherwise permits. Omitted (or empty) denies the harness credential document `$DSH_HOME/.env`; a non-empty list replaces that default. Denials name exact paths rather than roots on purpose: denying the whole harness home would also take away the model's documented access to its own session log.
-
-Enforcement is backend-shaped. Seatbelt appends a trailing `deny file-read* file-write*` (last matching rule wins) and bwrap maps `/dev/null` over each path after any workspace bind; Landlock grants are a pure allow-list, so a read grant on `/` cannot be subtracted from and `confine()` reports `partial` enforcement rather than pretending the boundary exists. `danger-full-access` confines nothing at all, so no denial applies there — the credential document is then protected only by its file mode, which does not stop a same-UID tool process.
-
 ## Surface
 
 - `ctx.sandboxPolicy.resolve({ session?, mode? })` — resolves one complete per-call policy. An explicit approved mode outranks the session's last `sandbox/mode` event, which outranks `defaultMode`; the session's immutable `cwd` is canonicalized with filesystem semantics before becoming `workspaceRoot`, otherwise the configured fallback applies. Canonicalization precedes lexical normalization so `symlink/..` agrees with process working-directory resolution.

-## 读取拒绝
-
-`readDenyPaths` 列出**受约束**执行绝不可读取的绝对路径，无论其模式在其他方面允许什么。省略（或为空）时拒绝 harness 凭据文档 `$DSH_HOME/.env`；非空列表则替换该默认值。拒绝项有意点名确切路径而非根目录：拒绝整个 harness home 会连带拿走模型对自己会话日志的既定访问。
-
-强制执行的形态由后端决定。Seatbelt 追加一条尾部 `deny file-read* file-write*`（最后匹配的规则胜出），bwrap 在任何工作区绑定之后把 `/dev/null` 映射到每个路径上；Landlock 的授权是纯粹的允许列表，`/` 上的读授权无法被扣除，因此 `confine()` 把强制执行报为 `partial`，而不是假装该边界存在。`danger-full-access` 根本不做任何约束，那里也就没有任何拒绝适用——凭据文档届时只受自身文件权限模式保护，而这挡不住同 UID 的工具进程。
-
 ## 接口
 
 - `ctx.sandboxPolicy.resolve({ session?, mode? })`：解析一项完整的逐调用策略。显式批准的模式优先于会话最后一条 `sandbox/mode` 事件，后者又优先于 `defaultMode`；会话不可变的 `cwd` 会先按文件系统语义规范化，再成为 `workspaceRoot`，否则使用配置的回退值。规范化先于词法归一化，因此 `symlink/..` 与进程工作目录解析保持一致。

Subject: [PATCH 047/102] feat(ui): drop the slash and the argument echo from
 the command row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The web command row renders `title · summary` from one logged command
lifecycle pair, and the two halves were written without knowing about each
other: the title was the dispatched line rebuilt from `command/run` and the
summary was `command/done`'s verbatim text, so every Access-chip pick read
`/permission workspace-write · Permission preset: workspace-write.` — the
command name twice and its argument twice.

The title is now the bare command name (no `/`, no arguments — the summary
already says what the command did), and a command handler's settlement text
never repeats the command's own name, so `/permission` returns `preset
workspace-write`. The row reads `permission · preset workspace-write`, and
the TUI notice still names the preset that now applies. The log is
unchanged: `command/run` keeps its structured name/args split for a richer
registered row.

+# Agent Note: Command row copy is split between the row and the handler
+
+Status: implemented
+
+English | [中文](2026-07-30-command-row-copy-contract.zh.md)
+
+## Problem
+
+The web command row renders `title · summary` from one logged [command lifecycle pair](../../proposed/architecture/2026-07-27-session-projection-and-command-log.md): the title was the dispatched line rebuilt from `command/run` (`/permission workspace-write`) and the summary was `command/done`'s verbatim `text` (`Permission preset: workspace-write.`). Both halves were written without knowing about the other, so the row said the command name twice and its argument twice — the single worst case being the row a user gets for every Access-chip pick.
+
+## Decision
+
+The row's two halves have disjoint jobs, and each side is written to its own half alone.
+
+The row title is the bare command name — no `/`, no arguments. The `/` belongs to the composer's input grammar, not to a settled record, and the argument is not the row's to report: the summary already says what the command did. `GenericCommandCard` keeps the `命令` fallback for a cross-window node whose `command/run` page fell out of the client's window.
+
+A command handler's settlement `text` therefore never repeats the command's own name, because the surface that renders it has already said it. `/permission` returns `preset workspace-write` and, bare, `current preset workspace-write (available: …)`. Read as a row this is `permission · preset workspace-write`; read as a standalone line — the TUI appends the same text as a notice — it still states which preset now applies.
+
+The log is unchanged: `command/run` keeps the structured `name`/`args` split, so a richer registered command row can still render arguments from the same node without a second data channel.
+
+## Alternatives considered
+
+**Keep the dispatched line as the title and only shorten the settlement text.** The argument would still appear on both sides of the separator (`permission workspace-write · preset workspace-write`), which is the repetition complained about.
+
+**Drop the settlement text from the collapsed row instead of the arguments.** It inverts the row's value: the outcome is what a durable record is for, and an error text would then have nowhere to land.
+
+**Have the row strip a leading command name from the settlement text.** Presentation would silently rewrite handler-authored text, and every handler that phrased its outcome differently would defeat the heuristic.
+
+## Consequences
+
+Every command row gets shorter, and the rule scales: a new command's author writes its outcome without knowing which surface renders it, and no surface has to de-duplicate. The cost is that the dispatched arguments leave the collapsed row — while a command is still executing the row shows only its name and `执行中…` — and that the no-repetition rule is a convention the reviewer enforces, not a gate. The `/permission` texts are pinned by the permission package's command tests, and the assembled row copy by the [seeded-history](../../../../apps/web/tests/snapshots/seeded-history/command-row.expected.md) web golden, which reaches a real settled command row keylessly because `/permission` runs entirely on the host.

+
+## Problem
+
+Web 命令行由一对落库的[命令生命周期事件](../../proposed/architecture/2026-07-27-session-projection-and-command-log.md)渲染出 `标题 · 摘要`：标题是由 `command/run` 重建的分派命令行（`/permission workspace-write`），摘要是 `command/done` 的原样 `text`（`Permission preset: workspace-write.`）。两半各自成文、互不知情，于是一行里命令名出现两次、参数也出现两次——最糟的一例正是用户每次用 Access chip 切换权限时得到的那一行。
+
+## Decision
+
+命令行两半的职责互不重叠，各自只按自己那一半来写。
+
+行标题就是裸命令名——没有 `/`，也没有参数。`/` 属于编辑器的输入语法，不属于一条已落定的记录；参数也不该由这一行来报告：摘要已经说清了这条命令做了什么。对于 `command/run` 那一页已滑出客户端窗口的跨窗口节点，`GenericCommandCard` 仍保留 `命令` 兜底标题。
+
+因此，命令 handler 的落定 `text` 绝不重复命令自身的名字——渲染它的界面已经说过一次了。`/permission` 返回 `preset workspace-write`，裸调用时返回 `current preset workspace-write (available: …)`。作为一行读是 `permission · preset workspace-write`；作为独立一句读——TUI 把同一段 text 作为通知追加——它依然说明了当下生效的是哪个预设。
+
+日志本身未变：`command/run` 保留结构化的 `name`／`args` 拆分，因此更丰富的已注册命令行仍可从同一个节点渲染参数，无需第二条数据通道。
+
+## Alternatives considered
+
+**保留分派命令行作标题，只缩短落定文案。** 参数仍会出现在分隔点两侧（`permission workspace-write · preset workspace-write`），而这正是被指出的重复。
+
+**从折叠行中去掉落定文案，而不是去掉参数。** 这颠倒了这一行的价值：持久记录存在的意义就是结果，而错误文案将无处落脚。
+
+**由这一行从落定文案里剥掉开头的命令名。** 呈现层会悄悄改写 handler 写就的文案，而任何换一种措辞表达结果的 handler 都会让这套启发式失效。
+
+## Consequences
+
+每一条命令行都变短了，而且这条规则可扩展：新命令的作者写结果时无需知道由哪个界面渲染，任何界面也都不必再去重。代价是分派参数离开了折叠行——命令仍在执行时，行上只有名字和 `执行中…`——以及"不重复"这条规则是靠评审执行的约定，而非门禁。`/permission` 的文案由 permission 包的命令测试钉住，装配后的行文案由 [seeded-history](../../../../apps/web/tests/snapshots/seeded-history/command-row.expected.md) web 预期输出钉住：因为 `/permission` 完全在 host 上执行，它能无密钥地抵达一条真实的落定命令行。

+The AppFrame exposed identical floating pills on both column borders. The left pill added unnecessary visual weight beside primary navigation, but the sidebar's resize interaction remains useful.
+
+## Decision
+
+AppFrame keeps the sidebar's 8px resize hit strip, `col-resize` cursor, pointer capture, animation-frame throttling, and width updates, but does not generate the sidebar handle's pill pseudo-element. The details boundary retains both its hit strip and floating pill.
+
+The layout component test continues to pin sidebar dragging and both handles' collapse lifecycle. A keyless browser scenario reads the generated pseudo-elements from the shipped composition and drags the invisible sidebar boundary to prove the interaction remains live.
+
+## Alternatives considered
+
+**Remove the sidebar drag interaction with the pill.** Rejected because the requested change is visual; removing a working geometry control would unnecessarily narrow the interaction.
+
+**Keep the pill but reduce its emphasis.** A smaller or lower-contrast pill still leaves an unwanted object on the sidebar boundary.
+
+## Consequences
+
+The sidebar boundary is visually quiet while pointer resizing remains available from the boundary and retains the resize cursor. Unlike the details control, that interaction has no visible pill.

+# Agent Note: 侧边栏缩放不显示胶囊
+
+Status: implemented
+
+[English](2026-07-30-sidebar-resize-without-visible-pill.md) | 中文
+
+## 问题
+
+AppFrame 在两个栏位边界都显示相同的浮动胶囊。左侧胶囊在主导航旁增加了不必要的视觉负担，但侧边栏的缩放交互仍有用。
+
+## 决策
+
+AppFrame 保留侧边栏宽 8px 的缩放命中条带、`col-resize` 光标、指针捕获、动画帧节流和宽度更新，但不再生成侧边栏手柄的胶囊形伪元素。详情栏边界同时保留命中条带和浮动胶囊。
+
+布局组件测试继续固定侧边栏拖动行为，以及两个手柄随面板折叠时的生命周期。一个无密钥浏览器场景读取实际交付组合所生成的伪元素，并拖动不可见的侧边栏边界，证明该交互仍然有效。
+
+## 曾考虑的替代方案
+
+**随胶囊一并移除侧边栏拖动交互。** 不予采纳，因为本次要求只改视觉表现；移除正常工作的几何控制会不必要地缩减交互方式。
+
+**保留胶囊，但降低其视觉强调。** 更小或对比度更低的胶囊仍会在侧边栏边界留下一个不需要的物体。
+
+## 后果
+
+侧边栏边界在视觉上保持简洁，同时仍可在边界处通过指针调整宽度，并保留缩放光标。与详情栏控件不同，该交互没有可见胶囊。

+Shell plugin: three-column AppFrame (drag handles and concession chain) plus the `ctx.layout` panel-geometry service; it registers into the runtime-owned `root` slot and declares `sidebar`, `conversation`, `details`, and `conversation.empty`. The sidebar resize boundary is an invisible hit strip, while the details boundary retains its floating pill; only details shrinks during concession and then auto-closes. A closed sidebar retains a 56px control rail while details closes to zero width.

 AppFrame always mounts the conversation and details columns; a connected Session renders through `SessionProvider`. The transient layout store starts both panels at their default widths and never reads or writes `localStorage`. Hero and other unselected states derive a zero rendered details width without changing that stored preference. AppFrame retains the last non-blank Session id across those states: the first Session opens at the default width, returning to the same Session restores its unchanged width, and selecting a different Session closes details before paint. The conversation owner share is empty, while the sidebar owner share contains only `collapsed` and `width`; registrants obtain business data from standard hooks and actions from their own inject faces.

Subject: [PATCH 053/102] fix(ui): drop the caption from the /permission error
 text too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round: the no-caption rule the Agent Note states applied only to the
success texts, leaving `permission · unknown permission preset "bogus" (…)`.
The error text now reads `unknown preset "bogus" (…)` and its exact wording
is pinned; the fixture mirror drops `JSON.stringify` for the host's own
quoting so the two cannot drift on a quoted argument.

The Note now states the line it draws: the rule bans a caption for the
command's own value, not the vocabulary, so `/plan`'s `Plan mode off.` and
`/goal`'s `Goal cleared.` conform as written — recorded with the broader
name-ban as a rejected alternative. The web row assertions are scoped to the
row so unrelated page text reading `permission` cannot satisfy them.

Subject: [PATCH 055/102] fix(web-config): close the wire boundary, the
 redacted-replace data loss, and three P2s
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Five findings from the #939 review, each reproduced before being fixed.

**Configuration reads are as privileged as writes.** `settings.describe`
returns every exposed namespace's configuration and `credentials.describe`
reports whether an arbitrary environment-variable name is configured and from
where — reconnaissance no anonymous caller should have. Both join
PRIVILEGED_METHODS, so the whole configuration plane is loopback-only until
real authentication exists; `trustedHosts` was never authentication. The model
catalog stays reachable: it carries no endpoints or key state, and a LAN
client's model picker legitimately needs it. Asserted over a real HTTP server,
because the Host header a browser actually sends is what decides this.

**The proxy serves only namespaces a registered model provider addresses.**
The settings seam is general — any plugin may register one — but the Web
configuration plane is the model-provider surface. Without the gate, every
future `settings.register()` would silently become remotely readable and
writable configuration. An unregistered namespace and an unexposed one answer
identically, so no caller can enumerate the registry one probe at a time.

**Path-addressed writes replace the redacted-document rebuild.** The editor
reads the REDACTED descriptor, so rebuilding a section from it and replacing
wholesale deleted every literal secret the wire never returned — reproduced as
`{baseURL, reasoning}` in, stored `apiKey` gone out. `settings.mutate` applies
set/unset ops to the section as it stands at the front of the seam's write
queue, and the client names only fields it can see, so an unseen secret is
untouched by construction rather than by care.

P2s in the same pass: `llm/adapters-updated` now contains async listener
rejections (an uncontained one escaped as unhandledRejection, contradicting
the documented "observer failures are contained"); llm-deepseek's retry-policy
swap uses the atomic `registration.replace` instead of dispose-then-register,
which published `[]` then `["deepseek-official"]` so an observer saw the
provider disappear and come back; and a transport rejection no longer strands
the page in `loading` or a card in `busy`, with removal failures surfaced on
the page banner instead of swallowed.

Subject: [PATCH 056/102] test(snapshot): re-record ACP goldens for the web
 card tag

web_fetch now projects presentationMeta ({url, statusCode, truncated}) onto its
tool/result, so the web-fetch scenario carries that meta; cordis-inspect-jsdoc
shifts with the widened ToolResultView type surface. Model-facing text is
unchanged. Refreshed keyless.

 **The prompt routes to the one credential editor.** A mounted, active adapter with a resolved, writable, unconfigured reference presents one action that opens Settings on Models. The existing DeepSeek setup card there exclusively owns the password input, `credentials.set({ref, value})`, write failures, and post-write refresh; the onboarding overlay never holds or submits a secret. An unavailable settings or credential capability keeps its deployment diagnostic and routes to the same page, while an absent adapter remains skipped because navigation cannot mount a Cordis plugin.
 
-**Unavailable capability states stay honest.** An absent configurable-provider entry suppresses the form because it cannot repair the composition. A present provider whose settings or credential capability cannot be resolved renders an actionable deployment diagnostic. Cancel dismisses the overlay for the current mounted surface and writes no completion fact. Settings, credential, provider-topology, and connection invalidations all refresh the shared join, so an external credential update closes an open prompt without a reload.

Subject: [PATCH 059/102] feat(settings): detect stale writers with a revision,
 and announce raw changes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The remaining P1 from the #939 review, plus the P2 it shares a mechanism with.

Nothing carried a version, so two tabs editing one namespace silently
overwrote each other — reproduced as tab B's `reasoning` lost to tab A's
older draft. The seam's per-namespace write queue orders writes; it cannot
tell a fresh writer from one replaying a snapshot a predecessor superseded.

Each namespace now carries a monotonic `revision` over its RAW section. A
write may send `expectedRevision`, checked at the FRONT of the queue (not at
call time, which would race the very predecessor it guards against); a
mismatch rejects with `SettingsConflictError` → `settings-conflict` on the
wire, carrying both revisions. The editor captures the revision it opened at
and, on conflict, asks the user to reopen rather than replaying its snapshot.

The same counter fixes the missing broadcast. `settings/updated` is gated on
the resolved value — correct for consumers, wrong for configuration surfaces:
storing an override equal to the composition base leaves the resolved value
alone while changing what the document says (the field is now overridden, not
inherited) and moving every open editor's revision. `settings/document-updated
(ns, revision)` fires on any raw-section change, in-process or external, and
`host/settings-changed` now rides it.

That event also closes the stale model picker: editing a provider's `models`
changes no route, so `llm/adapters-updated` never fired and an open picker
kept serving the old catalog. A change to an exposed provider namespace now
emits `host/models-changed` too — that namespace holds the catalog.

Docs: both sides of the five touched README pairs, a type-equiv block for
`SettingsPathOp`, and an Agent Note recording what the plane exposes and who
may overwrite what. The deferred wire-redaction gaps (secrets behind
union/intersection/transform, `.default(...)` in the served envelope, schema
text in rejection messages, `new Function` rehydration, pi-ai's `headers`) are
recorded as TODO(settings-wire-redaction) and in Known Limitations rather than
half-fixed.

+# Agent Note: what the configuration plane exposes, and who may overwrite what
+
+Status: implemented
+
+English | [中文](2026-07-30-config-plane-boundaries.zh.md)
+
+> Scope: the review round over the [web configuration plane](2026-07-30-web-config-plane.md) — which namespaces reach the wire, which callers reach them, and how an editor holding a partial, possibly stale view writes without destroying what it cannot see.
+
+## Problem
+
+The plane worked and was reachable by more callers, and with more authority, than its design claimed.
+
+`trustedHosts` gated only writes, so a declared LAN client could call `settings.describe` — every exposed namespace's configuration — and `credentials.describe`, which reports whether an arbitrary environment-variable name is configured and where it resolves from. That fence is a DNS-rebinding defense and says so; treating it as an authorization boundary for reads was a category error. Separately, the proxy served every registered namespace: the settings seam is deliberately general, so the first plugin to call `settings.register()` for its own configuration would silently become remotely readable and writable, without passing anywhere near a review of the web surface.
+
+The editor was worse than reachable — it was destructive. It reads the redacted descriptor, which by construction omits `role('secret')` fields. Clearing one field rebuilt the whole user section from that redacted copy and sent `settings.replace`, so a stored literal `apiKey` the wire had never returned was deleted as a side effect. Reproduced directly: `{baseURL, reasoning}` in, `apiKey` gone. Row removal took the same path. And nothing carried a version, so two tabs editing one namespace silently overwrote each other; the seam's per-namespace write queue orders writes but cannot tell a fresh writer from one replaying a stale snapshot.
+
+Three smaller defects sat beside them. `llm/adapters-updated` documented contained observer failures but only caught synchronous ones, so an async listener's rejection escaped as an unhandled rejection. llm-deepseek's retry-policy swap disposed its registration before re-registering, publishing an empty route set between the two — an observer saw the provider disappear and come back, despite a comment claiming no such window. And a transport rejection during the page's credential enrichment escaped `load()`, stranding the page in `loading` with no error shown.
+
+## Decision
+
+**Reading configuration is as privileged as writing it.** `settings.describe` and `credentials.describe` join the loopback-only set, so the whole configuration plane stays same-origin until real authentication exists. The model catalog (`llm.providers`, `llm.models`) deliberately does not: it carries provider ids, display names, and model lists — no endpoints, no key state — and a LAN client's model picker needs it. The boundary is asserted over a real HTTP server rather than a hand-assembled request, because the `Host` header a browser actually sends is what decides it.
+
+**The plane serves exactly the namespaces a registered model provider addresses.** `ctx.llm.listConfigurableProviders()` is the allow-list, so the product boundary is enforced rather than inferred from today's plugin set, and a future namespace becomes web-configurable only by joining that directory. An unregistered namespace and an unexposed one answer identically (`settings-not-exposed`), so probing cannot enumerate the registry.
+
+**A caller with a partial view names the field it means.** `Settings.mutate(ns, ops)` applies `set`/`unset` path ops to the section as it stands at the front of the write queue. The client builds ops by diffing its opening snapshot against its draft, so it mentions only fields it can see: a secret absent from both sides produces no op and survives by construction, not by care. `replace` remains the deliberate wholesale reset.
+
+**Staleness is detected, not ordered away.** Each namespace carries a monotonic `revision` over its RAW section; writes may carry `expectedRevision`, and a mismatch rejects with `SettingsConflictError` → `settings-conflict` on the wire, both revisions attached. The editor captures the revision it opened at and, on conflict, tells the user to reopen rather than replaying its snapshot.
+
+**The raw layer gets its own event.** `settings/updated` stays gated on the resolved value — that is what a consumer means by change. `settings/document-updated (ns, revision)` fires on any raw-section change, because a configuration surface must learn that a field went from inherited to overridden (same resolved value, different meaning) and that its held revision is stale. The host frame `host/settings-changed` now rides this event, and a change to an exposed provider namespace also emits `host/models-changed`: that namespace holds the provider's catalog, which no route change announces.
+
+## Alternatives considered
+
+- **A deployment-declared namespace allowlist on the proxy config** — more general, but it moves the product boundary to whoever writes cordis.yml, and an empty default would break the shipped page until every deployment opted in. The provider directory already states exactly which namespaces are model configuration.
+- **Opt-in metadata at `settings.register()`** — the most honest semantics (the namespace's owner declares its own exposure), and the largest change: the seam's public interface, both LLM plugins, and their docs. Recorded as the shape to adopt if a non-LLM namespace ever needs the plane.
+- **Distinguishing "unregistered" from "registered but unexposed"** — better diagnostics, and a namespace-enumeration oracle. The uniform answer is deliberate.
+- **Detecting conflicts by diffing instead of a revision** — comparing the submitted base against storage would work for whole-section writes, but the editor holds a REDACTED section: it cannot produce a comparable base, which is the same reason it cannot safely `replace`. A counter needs neither.
+- **Fixing the redaction gaps in this round** — `redactSecrets` walks only `object`/`dict`/`array`, so a secret behind a union, intersection, or transform is returned verbatim with an empty `secrets` list; `schema.toJSON()` carries a secret field's `.default(...)`; write-rejection messages return schema text that may quote the input; the client rehydrates the envelope through schemastery's `new Function`; and pi-ai's plain-string `headers` dict can legitimately hold `Authorization`. All confirmed, all deliberately left for a fail-closed `describeForWire()` that refuses a schema it cannot prove safe. They are recorded as `TODO(settings-wire-redaction)` and in the owning READMEs' Known Limitations rather than half-fixed here.
+
+## Consequences
+
+A LAN client on a `trustedHosts` deployment can no longer render the settings page at all; loopback is the configuration surface. A plugin that registers a settings namespace is not web-configurable until it also registers a configurable provider — deliberate, and the reason `settings-not-exposed` names the boundary in its message. `SettingsDescriptor` gained a required `revision`, so any programmatic constructor of a descriptor-shaped value must supply it, and `settings/document-updated` is a new event any provider-side listener may now observe. Clients that ignore `expectedRevision` keep last-write-wins semantics unchanged. Deferred: the fail-closed wire describe (with the `headers` and envelope-sanitization work it carries), and a non-executable browser schema protocol.

+# Agent Note：配置面暴露什么，以及谁有权覆盖什么
+
+Status: implemented
+
+[English](2026-07-30-config-plane-boundaries.md) | 中文
+
+> 范围：针对 [Web 配置面](2026-07-30-web-config-plane.md)的评审轮——哪些 namespace 能抵达协议、哪些调用方能抵达它们，以及一个只持有局部、且可能过期视图的编辑器该如何写入，才不会毁掉它看不见的东西。
+
+## 问题
+
+这个面能用，但能触达它的调用方、以及它们所拥有的权限，都比设计声称的更多。
+
+`trustedHosts` 只拦住了写入，因此一个已声明的 LAN 客户端可以调用 `settings.describe`——拿到每个已暴露 namespace 的配置——以及 `credentials.describe`，后者会报告任意一个环境变量名是否已配置、又从何处解析。那道 fence 是 DNS 重绑定防御，它自己也是这么写的；把它当作读取的授权边界，是一次范畴错误。另一件事是：代理服务于每一个已注册的 namespace。settings seam 是刻意做成通用的，因此第一个为自身配置调用 `settings.register()` 的插件，就会悄无声息地变成可远程读写，而完全不必经过任何针对 Web 表层的评审。
+
+编辑器比"可触达"更糟——它是破坏性的。它读到的是脱敏后的 descriptor，后者按构造省略了 `role('secret')` 字段。清空其中一个字段，会用这份脱敏副本重建整个用户分节并发出 `settings.replace`，于是一个协议从未回传过的已存字面 `apiKey` 被顺带删除。这一点被直接复现：输入 `{baseURL, reasoning}`，输出时 `apiKey` 消失。删除整行走的是同一条路径。而且没有任何东西携带版本，因此两个标签页编辑同一个 namespace 会静默互相覆盖；seam 的逐 namespace 写队列只排定写入次序，分辨不出一个新写方与一个重放过期快照的写方。
+
+另有三个较小的缺陷与之并列。`llm/adapters-updated` 的文档写着观察者失败会被收容，却只捕获同步失败，于是异步 listener 的 rejection 作为 unhandled rejection 逃逸。llm-deepseek 的重试策略换路由先释放注册、再重新注册，在两者之间发布了一个空路由集——观察者会看到该提供方消失又回来，尽管注释宣称不存在这样的空窗。还有，页面做凭据增强时的传输层 rejection 会逃出 `load()`，把页面卡在 `loading` 且不显示任何错误。
+
+## 决策
+
+**读配置与写配置同样特权。**`settings.describe` 与 `credentials.describe` 加入仅限回环的集合，因此在真正的认证层出现之前，整个配置面都保持同源。模型目录（`llm.providers`、`llm.models`）刻意不在其中：它携带的是提供方 id、显示名与模型列表——没有端点、没有密钥状态——而 LAN 客户端的模型选择器正需要它。这条边界由一台真实 HTTP 服务器来断言，而不是手工拼装的请求，因为真正决定它的，是浏览器实际发出的那个 `Host` 头。
+
+**这个面恰好服务于已注册模型提供方所指向的那些 namespace。**`ctx.llm.listConfigurableProviders()` 就是允许列表，于是产品边界是被执行的，而不是从今天的插件集合里推断出来的；将来的 namespace 只有加入该目录才会变得可在 Web 上配置。未注册的 namespace 与未暴露的 namespace 得到完全相同的答复（`settings-not-exposed`），因此探测无法枚举注册表。
+
+**持有局部视图的调用方，点名它真正要改的字段。**`Settings.mutate(ns, ops)` 会把 `set`/`unset` 路径 op 施加在写入排到队首那一刻的分节上。客户端通过对比自己打开时的快照与草稿来构造 op，因此它只提及自己看得见的字段：两侧都没有的机密不会产生任何 op，它的留存是构造使然，而非小心使然。`replace` 仍是那个刻意的整体重置。
+
+**过期是被检测出来的，而不是靠排序绕过去的。**每个 namespace 都带有一个针对其**原始**分节的单调 `revision`；写入可携带 `expectedRevision`，不匹配即以 `SettingsConflictError` 拒绝——在协议上是 `settings-conflict`，并附上两个 revision。编辑器记住自己打开时的 revision，冲突时请用户重新打开，而不是把自己的快照重放上去。
+
+**原始层拥有自己的事件。**`settings/updated` 仍以解析值为门槛——那才是消费方所说的"变化"。`settings/document-updated (ns, revision)` 则在任何原始分节变化时触发，因为配置界面必须知道某个字段从继承变成了覆盖（解析值相同，含义不同），也必须知道自己持有的 revision 已经过期。host 帧 `host/settings-changed` 现在搭乘这个事件；而已暴露提供方 namespace 的变更还会额外发出 `host/models-changed`：该 namespace 正持有这个提供方的目录，而没有任何路由变更会宣告它。
+
+## 曾考虑的替代方案
+
+- **在代理配置上做部署声明式的 namespace 白名单**——更通用，但它把产品边界交给了写 cordis.yml 的人，而空的默认值会让已交付的页面在每个部署显式开启之前直接失效。提供方目录本就精确地说明了哪些 namespace 属于模型配置。
+- **在 `settings.register()` 处 opt-in metadata**——语义最正（由 namespace 的属主自行声明其暴露与否），改动也最大：seam 的公共接口、两个 LLM 插件，以及它们的文档。记录为：一旦某个非 LLM 的 namespace 确实需要这个面，就采用这个形状。
+- **区分"未注册"与"已注册但未暴露"**——诊断更好，同时也是一台 namespace 枚举预言机。统一答复是刻意为之。
+- **用 diff 而非 revision 来检测冲突**——对整分节写入而言，拿提交时的基线与存储比对是可行的，但编辑器持有的是**脱敏后**的分节：它给不出可比对的基线，这与它不能安全地 `replace` 是同一个原因。计数器两者都不需要。
+- **本轮就修掉脱敏的缺口**——`redactSecrets` 只遍历 `object`/`dict`/`array`，因此藏在 union、intersection 或 transform 之后的机密会被原样返回，且 `secrets` 列表为空；`schema.toJSON()` 会带上 secret 字段的 `.default(...)`；写入拒绝的消息返回的是可能引用了输入的 schema 文本；客户端通过 schemastery 的 `new Function` 重建信封；而 pi-ai 那个纯字符串的 `headers` 字典完全可以合法地放下 `Authorization`。全部经确认属实，也全部刻意留给一个 fail-closed 的 `describeForWire()`——它会拒绝自己无法证明安全的 schema。它们被记录为 `TODO(settings-wire-redaction)` 以及各属主 README 的 Known Limitations，而不是在这里做一半。
+
+## 影响
+
+`trustedHosts` 部署下的 LAN 客户端已经完全无法渲染设置页；配置表层就是回环。注册了 settings namespace 的插件，在它同时注册可配置提供方之前不会变得可在 Web 上配置——这是刻意的，也正是 `settings-not-exposed` 要在消息里点明这条边界的原因。`SettingsDescriptor` 新增了必填的 `revision`，因此以编程方式构造 descriptor 形状值的地方都必须提供它；`settings/document-updated` 是一个新事件，provider 侧的任何 listener 现在都可以观察它。忽略 `expectedRevision` 的客户端，其后写胜出的语义完全不变。延后事项：fail-closed 的协议 describe（连同它所承载的 `headers` 与信封净化工作），以及一套客户端无法执行的浏览器 schema 协议。

 ## Known Limitations and Deferred Work
 
+- **Rehydration executes the served envelope** — `rehydrateSchema` reconstructs a live schemastery validator, and schemastery revives serialized callbacks through `new Function`, so the schema envelope is executable content rather than inert data. That is acceptable only because the envelope comes from the same host that serves the page; a browser schema protocol should carry a description the client cannot execute, which is deferred with the settings seam's [wire-boundary work](../../settings/settings/README.md#known-limitations-and-deferred-work).
 - **Validation is draft-level, not per-field** — `validateDraft` reports schemastery's first failure message (which names the `$.path`); per-field error mapping is deferred until a consumer needs it.
 - **No generic renderer** — a schema-driven form component was built and then replaced by the hand-written Models editor ([Agent Note](../../../.agents/notes/implemented/architecture/2026-07-30-web-config-plane.md)); if a future page needs to edit arbitrary sections, it starts from these helpers, not from a resurrected generic renderer, unless the note's trade-off changes.

 ## Known Limitations and Deferred Work
 
+- **重建 schema 会执行所收到的信封**——`rehydrateSchema` 会重建一个活的 schemastery 校验器，而 schemastery 通过 `new Function` 复活序列化过的 callback，因此 schema 信封是可执行内容，而非惰性数据。这只有在信封来自提供该页面的同一 host 时才可接受；面向浏览器的 schema 协议应当传递客户端无法执行的描述，此项与 settings seam 的[协议边界工作](../../settings/settings/README.md#known-limitations-and-deferred-work)一并暂缓。
 - **校验是草稿级的，而非逐字段**——`validateDraft` 报告 schemastery 的第一条失败消息（其中会点名 `$.path`）；逐字段的报错映射延后到出现需要它的消费方再做。
 - **没有通用渲染器**——一个 schema 驱动的表单组件曾被构建出来，随后被手写的 Models 编辑器取代（[Agent Note（agent 决策记录）](../../../.agents/notes/implemented/architecture/2026-07-30-web-config-plane.md)）；若未来有页面需要编辑任意分节，起点是这些辅助函数，而不是复活后的通用渲染器——除非该 note 的权衡发生变化。

 Rows are the *configured* providers (their profile resolves in the owning namespace); a whole-section provider whose key is not configured anywhere (the first-run DeepSeek posture) renders as its open setup card instead of a row, and the add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor is a hand-written card per adapter family: the primary field is a single **API key** input — the page never asks for an environment-variable name; a typed key stores **write-only** through `credentials.set` under the profile's reference, deriving `<ROUTE>_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. The collapsed 自定义设置 fold carries the curated extras — `baseURL` for both families (the deepseek placeholder shows the public endpoint), plus `reasoningEffort` (deepseek) or `reasoning` (pi-ai); every other profile field stays owned by `settings.yaml`. A row is deletable only when the user layer alone carries it (removal restores the composition base).
 
-Apply semantics mirror the settings seam: an edit without removals lands as a minimal `settings.update` merge patch, while clearing a fold field back to inherited or deleting a row lands through `settings.replace` of the whole user section so removals actually take effect — safe wholesale, because the section stores key references, never key values. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.
+Every edit lands as `settings.mutate` path ops against the stored section — a set per changed field, an unset per cleared one, and a single unset for a deleted row. The page only ever holds the REDACTED descriptor, so it names the fields it can see rather than rebuilding a section: a stored literal secret it never received is mentioned by no op and survives. Each write carries the `revision` the card opened at, so a concurrent write from another tab or an external `settings.yaml` edit is refused as `settings-conflict` and the card asks the user to reopen instead of replaying its stale snapshot.

A profile schema without the conventional fields renders the hint alone, and the two curated layouts key on the `llm-deepseek`/`llm-pi-ai` namespaces by name.

 The `command.*` and `skill.*` domains expose the host command registry and skill catalog to clients. Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `skill.list` serves the browser's user-selected model-reference path, so it returns only skills that are both model-invocable and user-invocable; this domain has no direct skill-loading RPC. `command.execute` runs a slash-command line host-side with pure admission semantics: the response reports whether the line resolved to a handler plus the minted lifecycle `commandId` when it did (correlating the acknowledgment with the flow node), while the outcome rides the durably logged `command/run`/`command/done` lifecycle pair broadcast on the mux stream; the carrier's request signal cancels the running handler. `host/commands-changed` is the catalog invalidation frame: clients refetch `command.list` instead of diffing.
 
-The `settings.*`, `credentials.*`, and `llm.*` domains are the configuration-page wire. `settings.describe` serves every registered namespace with its serialized schemastery schema plus redacted layered values (resolved/`base`/`user` — a field's presence in `user` marks it user-overridden) and the `secrets` slot list; `settings.update`/`settings.replace` write the user layer and answer with the namespace's new redacted view, folding every seam refusal into `settings-rejected`. Secret-role values never ride any response in any layer; a secret crosses the wire in exactly one direction — inside an `update` patch or `credentials.set`. `credentials.describe` returns value-free views (`configured`/`source`/`writable`), and `credentials.set`/`credentials.unset` map a shadowed-reference refusal onto `credential-rejected`. `llm.providers` merges the configurable-provider directory with live routes (dormant entries carry `active: false`; undeclared live routes append with no settings address) and `llm.models` is the session-independent catalog. Three invalidation frames keep every surface converged without polling: `host/settings-changed {ns}` (`settings/updated` passthrough — RPC writes and external `settings.yaml` edits alike), `host/credentials-changed {ref}` (reference names only, never values), and `host/models-changed` (`llm/adapters-updated` passthrough). The browser carrier restricts the four write methods (`settings.update`/`settings.replace`/`credentials.set`/`credentials.unset`) to loopback, same-origin requests — the `host.pickDirectory` privileged set.

+The `settings.*`, `credentials.*`, and `llm.*` domains are the configuration-page wire. The settings domain serves exactly the namespaces a registered configurable provider addresses (`ctx.llm.listConfigurableProviders()`): the seam is general, but this plane is the model-provider surface, so a namespace nothing in the directory names is neither described nor writable here and answers `settings-not-exposed` — the same answer an unregistered namespace gets, so no caller can enumerate the registry by probing. `settings.describe` returns each exposed namespace's serialized schemastery schema, redacted layered values (resolved/`base`/`user` — a field's presence in `user` marks it user-overridden), the `secrets` slot list, and the section's `revision`. `settings.update`/`settings.replace` write the user layer; `settings.mutate` applies path ops (`set`/`unset`) against the section as stored, which is the removal path for a client holding the redacted view — rebuilding a section from it and replacing wholesale would delete the secrets the wire never returned. Any write may carry `expectedRevision`; a stale one answers `settings-conflict` with both revisions rather than overwriting the writer that landed first, and every other seam refusal folds into `settings-rejected`. Secret-role values never ride any response in any layer; a secret crosses the wire in exactly one direction — inside an `update`/`mutate` payload or `credentials.set`. `credentials.describe` returns value-free views (`configured`/`source`/`writable`), and `credentials.set`/`credentials.unset` map a shadowed-reference refusal onto `credential-rejected`. `llm.providers` merges the configurable-provider directory with live routes (dormant entries carry `active: false`; undeclared live routes append with no settings address) and `llm.models` is the session-independent catalog. Three invalidation frames keep every surface converged without polling: `host/settings-changed {ns}` (`settings/document-updated` passthrough, so a raw change whose resolved value is unchanged still reaches clients), `host/credentials-changed {ref}` (reference names only, never values), and `host/models-changed` — fired both by `llm/adapters-updated` and by a change to an exposed provider namespace, whose settings carry that provider's catalog and endpoint. The browser carrier restricts the whole configuration plane, reads included (`settings.describe`/`update`/`replace`/`mutate`, `credentials.describe`/`set`/`unset`), to loopback same-origin requests — the `host.pickDirectory` privileged set.

 `command.*` 与 `skill.*` 领域向客户端暴露宿主命令注册表和技能目录。每个方法都通过 `sessionId` 寻址一个会话的 Agent（被服务的会话必有 Agent；`command.*` 经由与 `session.*` 相同的路径恢复冷会话，而 `skill.list` 从会话头解析项目根目录，不触碰 Agent 注册表）。`skill.list` 服务于浏览器中由用户选择的模型引用路径，因此仅返回模型和用户均可调用的 skill；该领域没有直接加载 skill 的 RPC。`command.execute` 在宿主侧运行一条斜杠命令行，语义为纯准入：响应报告该行是否解析到处理器，并在解析到时回带铸造的生命周期 `commandId`（将本次确认与流节点关联）；结局经由持久落账并在 mux 流广播的 `command/run`/`command/done` 生命周期事件对承载；载体的请求信号可取消正在运行的处理器。`host/commands-changed` 是目录失效帧：客户端重新拉取 `command.list` 而不是做差分。
 
-`settings.*`、`credentials.*` 与 `llm.*` 领域是配置页协议。`settings.describe` 为每个已注册 namespace 提供其序列化 schemastery schema，外加脱敏后的分层值（resolved/`base`/`user`——字段出现在 `user` 中即标记其被用户覆盖）与 `secrets` 槽位列表；`settings.update`/`settings.replace` 写入用户层，并以该 namespace 的新脱敏视图作答，把每种 seam 拒绝折叠为 `settings-rejected`。secret 角色的值绝不在任何一层搭乘任何响应；secret 只沿一个方向跨越协议——在 `update` patch 或 `credentials.set` 之内。`credentials.describe` 返回不含值的视图（`configured`/`source`/`writable`），`credentials.set`/`credentials.unset` 则把被遮蔽引用的拒绝映射为 `credential-rejected`。`llm.providers` 把可配置提供方目录与存活路由合并（休眠条目携带 `active: false`；未声明的存活路由追加在后，不带 settings 地址），`llm.models` 则是与会话无关的目录。三个失效帧让每个面无需轮询即保持收敛：`host/settings-changed {ns}`（`settings/updated` 透传——RPC 写入与外部 `settings.yaml` 编辑一视同仁）、`host/credentials-changed {ref}`（只带引用名，绝不带值）与 `host/models-changed`（`llm/adapters-updated` 透传）。浏览器载体将四个写方法（`settings.update`/`settings.replace`/`credentials.set`/`credentials.unset`）限制为仅接受来自回环地址的同源请求——即 `host.pickDirectory` 所在的特权集合。未装 settings 或凭据 provider 的组合会以指名缺失插件、包含解决建议的 `internal` 错误应答这些领域。
+`settings.*`、`credentials.*` 与 `llm.*` 领域是配置页协议。settings 领域只服务于已注册可配置提供方所指向的那些 namespace（`ctx.llm.listConfigurableProviders()`）：seam 本身是通用的，但这个面是模型提供方表层，因此目录中无人点名的 namespace 在这里既不会被描述也不可写入，只会得到 `settings-not-exposed`——未注册的 namespace 得到的是同一个答复，因此没有调用方能靠逐个探测把注册表枚举出来。`settings.describe` 为每个已暴露 namespace 提供其序列化 schemastery schema、脱敏后的分层值（resolved/`base`/`user`——字段出现在 `user` 中即标记其被用户覆盖）、`secrets` 槽位列表，以及该分节的 `revision`。`settings.update`/`settings.replace` 写入用户层；`settings.mutate` 则在已存分节上施加路径 op（`set`/`unset`），这是持有脱敏视图的客户端的删除路径——据此重建分节再整体替换，会删掉协议从未回传过的那些机密。任何写入都可携带 `expectedRevision`；过期的期望值会以 `settings-conflict` 连同两个 revision 作答，而不是覆盖先落地的那个写方，其余每种 seam 拒绝则折叠为 `settings-rejected`。secret 角色的值绝不在任何一层搭乘任何响应；secret 只沿一个方向跨越协议——在 `update`/`mutate` 载荷或 `credentials.set` 之内。`credentials.describe` 返回不含值的视图（`configured`/`source`/`writable`），`credentials.set`/`credentials.unset` 则把被遮蔽引用的拒绝映射为 `credential-rejected`。`llm.providers` 把可配置提供方目录与存活路由合并（休眠条目携带 `active: false`；未声明的存活路由追加在后，不带 settings 地址），`llm.models` 则是与会话无关的目录。三个失效帧让每个面无需轮询即保持收敛：`host/settings-changed {ns}`（`settings/document-updated` 透传，因此解析值未变的原始变更同样能到达客户端）、`host/credentials-changed {ref}`（只带引用名，绝不带值），以及 `host/models-changed`——它既由 `llm/adapters-updated` 触发，也由某个已暴露提供方 namespace 的变更触发，因为该提供方的设置正承载着它的目录与端点。浏览器载体把整个配置面（含读取：`settings.describe`/`update`/`replace`/`mutate` 与 `credentials.describe`/`set`/`unset`）限制为仅接受来自回环地址的同源请求——即 `host.pickDirectory` 所在的特权集合。未装 settings 或凭据 provider 的组合会以指名缺失插件、包含解决建议的 `internal` 错误应答这些领域。

 ## Known Limitations and Deferred Work
 
 - **A settings `models` list replaces the composition list wholesale** — settings-layer merging is per-field, and arrays are one field; per-entry catalog merging would need a keyed shape.
-- **`Config.apiKey` is schema-tagged `role('secret')` but not yet masked anywhere** — the settings `describe()` envelope returns values verbatim; the wire/UI layer that must redact secret-role fields ships with the settings RPC surface.
+- **`Config.apiKey` is redacted on the wire but still a stored literal** — `describe({ redactSecrets: true })` strips it and reports the slot, so a configuration UI never receives the value; the key is nonetheless stored in the settings document rather than the credential store, so prefer `apiKeyEnv`.
 - **`tool_choice` is not mapped** — not part of the core vocabulary (MVP cut, shared with the pi-ai twin).
 - **Requests use raw `fetch`, not `@cordisjs/plugin-http`** — no shared proxy/interception configuration; adoption is deferred until a second adapter wants it (`TODO(http)`).
 - **Serialization flattens user and tool-result content to text blocks** — plugin-added block types are skipped, and empty tool output crosses the wire as the literal `(no output)`.

 ## 已知限制与暂缓事项
 
 - **settings 的 `models` 列表会整体替换组合列表**：settings 层按字段合并，而数组是单个字段；按条目合并 catalog 需要带键的形状。
-- **`Config.apiKey` 已在 schema 中标注 `role('secret')`，但尚未在任何地方脱敏**：settings 的 `describe()` 信封原样返回值；负责对 secret 角色字段脱敏的 wire／UI 层将随 settings RPC 面一起交付。
+- **`Config.apiKey` 在协议上已脱敏，但仍是一个已存的字面值**：`describe({ redactSecrets: true })` 会把它剥离并报告该槽位，配置 UI 因此永远收不到该值；但这个密钥仍存放在 settings 文档而非凭据存储中，所以请优先使用 `apiKeyEnv`。
 - **未映射 `tool_choice`**：它不属于核心词汇（MVP 取舍，与 pi-ai twin 共享）。
 - **请求使用原始 `fetch`，而非 `@cordisjs/plugin-http`**：没有共享 proxy／拦截配置；采用暂缓到第二个适配器需要该功能时（`TODO(http)`）。
 - **序列化会将 user 与工具结果内容展平为文本块**：会跳过插件添加的块类型，空工具输出会以字面 `(no output)` 通过协议发送。

 ## Known Limitations and Deferred Work
 
 - **Settings can add or override routes, not remove composition routes** — the user layer merges over the composition `base`, so deleting a `cordis.yml`-provided provider is a composition change; `replace` on the namespace only resets the user layer.
-- **`apiKey` is schema-tagged `role('secret')` but not yet masked anywhere** — the settings `describe()` envelope returns values verbatim; the wire/UI layer that must redact secret-role fields ships with the settings RPC surface.
+- **`headers` can carry a credential the redactor never sees** — the profile's `headers` dict is plain strings, so `Authorization` or `api-key` set there is returned verbatim by a redacted `describe()` and rendered by any configuration UI. Store credentials as `apiKeyEnv` references; making the dict write-only is deferred with the rest of the [wire-boundary work](../llm/README.md#known-limitations-and-deferred-work).
 - **Catalog membership is required** — custom model ids that are absent from the installed pi-ai catalog fail with `UNKNOWN_MODEL`, even when a provider profile supplies a custom endpoint.
 - **`GenerateOptions.stop` is unsupported** — pi-ai's common stream options cannot guarantee stop-sequence behavior across providers, so the adapter rejects the field.
 - **In-history `system` messages use pi-ai's common context conversion** — provider-specific placement follows pi-ai rather than a harness-owned wire override.

 ## 已知限制与暂缓事项
 
 - **settings 能新增或覆盖路由，但不能移除组合路由**：用户层合并在组合 `base` 之上，因此删除 `cordis.yml` 提供的提供方属于组合变更；对该 namespace 执行 `replace` 只会重置用户层。
-- **`apiKey` 已在 schema 中标注 `role('secret')`，但尚未在任何地方脱敏**：settings 的 `describe()` 信封原样返回值；负责对 secret 角色字段脱敏的 wire／UI 层将随 settings RPC 面一起交付。
+- **`headers` 可能承载一条脱敏器看不见的凭据**：profile 的 `headers` 是纯字符串字典，因此设在其中的 `Authorization` 或 `api-key` 会被脱敏后的 `describe()` 原样返回，并被任何配置 UI 渲染出来。请把凭据存为 `apiKeyEnv` 引用；把该字典整体改为只写与其余[协议边界工作](../llm/README.md#known-limitations-and-deferred-work)一并暂缓。
 - **必须属于 catalog**：已安装 pi-ai catalog 中不存在的自定义模型 id 会以 `UNKNOWN_MODEL` 失败，即使提供方 profile 配置了自定义端点。
 - **不支持 `GenerateOptions.stop`**：pi-ai 的通用流选项无法保证所有提供方都支持 stop sequence，因此适配器会拒绝该字段。
 - **历史中的 `system` 消息使用 pi-ai 通用上下文转换**：提供方特定位置由 pi-ai 决定，而非由 harness 拥有的协议覆盖决定。

 - `describe(options?)` — one descriptor per namespace (`schema.toJSON()` envelope, resolved value, detached `base`/`user` layers, `applies`) for configuration surfaces; a field's presence in `user` is what marks it user-overridden. `describe({ redactSecrets: true })` strips `role('secret')` fields from every layer and adds the `secrets` slot list (`{ path, set }`); every wire surface MUST pass it, and the pure `redactSecrets(schema, value)` walker is exported for other wires.
 - `get(ns)` — resolved value, `undefined` while unregistered.
 - `update(ns, patch)` — deep-merges the plain-object patch into the user section only (never the `base`), validates the resolved candidate, persists through the provider, then commits. Patches must be JSON-shaped data: a Date, Map, BigInt, non-finite number, or circular reference rejects with its `$`-rooted path before anything persists (YAML/JSON storage would silently distort such values on reload). Validation failure rejects before anything is persisted; a read-only provider (`writable: false`) rejects every write. Writes to one namespace are serialized in call order.

+- `mutate(ns, ops)` — applies ordered `{ op: 'set' | 'unset', path }` edits to the section as it stands when the write reaches the front of the queue. This is the removal path for any caller holding an INCOMPLETE view: a configuration UI reads the redacted descriptor, so rebuilding a section from it and replacing wholesale deletes every secret the wire never returned, while an op names the one field it means.
+- Every write takes an optional `expectedRevision`. Each descriptor carries the namespace's `revision`, a monotonic counter over its RAW section; a write whose expectation no longer matches rejects with `SettingsConflictError` (`code: 'SETTINGS_CONFLICT'`, both revisions attached) instead of overwriting the writer that landed first. The write queue orders writes but cannot by itself tell a fresh writer from one holding a stale snapshot.
 - Resolved values are deep-frozen snapshots. Watchers receive `(next, prev)` after each commit: invocations of one callback run asynchronously, one at a time, in commit order (a slow stale invocation can never apply after a newer one), and failures — sync throws and async rejections alike — are contained. After a watch disposer returns, no further invocation starts (one already queued is skipped); an invocation already started still settles. The `settings/updated` event fans out one listener at a time, so one throwing listener cannot starve the rest; an async listener's rejection is contained and logged, which is why `INVARIANT`-coded failures rethrow only from synchronous listeners.
 - Service teardown refuses new writes and watcher starts, then drains every queued write and every started watcher invocation before disposal completes; a write whose registrant fiber was disposed mid-flight still reaches storage but commits and notifies nobody.

 ## Known Limitations and Deferred Work
 
 - **Single user layer** — resolution knows schema defaults, one composition `base`, and one user document; there is no project/managed layering or per-value provenance yet.
+- **`redactSecrets` is not a proven wire boundary** — the walker follows `object`/`dict`/`array`, so a `role('secret')` reached only through a union, intersection, or transform is returned VERBATIM with an empty `secrets` list, and `schema.toJSON()` carries a secret field's `.default(...)` to every client. Neither case is rejected; a schema whose secrets are not reachable through the walked containers must not be registered on a wire-exposed namespace. A fail-closed `describeForWire()` — one that refuses a schema it cannot prove safe, and sanitizes the serialized envelope and error text — is the real answer and is deferred.
 - **Cross-process concurrency is provider-defined** — the seam serializes writes per namespace in-process only; concurrent processes converge by provider behavior (the local file provider read-modify-writes under a writer lock, so namespaces survive concurrent writers and same-namespace conflicts resolve last-write-wins).

 - 解析值是深冻结快照。每次提交后观察者收到 `(next, prev)`：同一回调的调用异步、逐次、按提交顺序执行（慢的旧调用绝不会覆盖更新的结果），异常——同步抛出与异步拒绝——均被隔离。watch 的 disposer 返回后不再启动新的调用（已排队的那一次会被跳过）；已启动的调用仍会结算。`settings/updated` 事件逐 listener 扇出，一个抛错的 listener 不会饿死其余 listener；异步 listener 的拒绝会被隔离并记入日志，这正是 `INVARIANT` 编码的失败只从同步 listener 重新抛出的原因。

Subject: [PATCH 060/102] fix(ui-models): contain the card's credential probe
 rejection

The review named this call site with the other two, and the previous pass
missed it: the editor card's mount-time `credentials.describe` had only a
fulfillment handler, so a transport failure reached the browser as an
unhandled rejection.

The probe is a placeholder hint ("already configured"), never a precondition
for editing, so it now renders without the hint rather than failing. Covered
by a test that fails without the handler.

-Both seats format `node.time` through `formatMessageClock`: same calendar day → `HH:mm`, earlier this year → `M月D日 HH:mm`, other years → `YYYY年M月D日 HH:mm`. `useCalendarDay` is a component-local day tick (timeout to the next local midnight) so memoized rows re-render when the calendar day changes without a new framework hook. `MessageItem` places the label before copy (figma `388:20051`). `ChatView` derives turn-tail seqs via `assistantActionsSeqs` and withholds `time` for mid-turn content; `AssistantMarkdown` places the row after branch (figma `43:32997`) only when `streaming` is false, the event time is known, and the node has non-empty text content. Think-only nodes, mid-turn narration, and the streaming tail omit the row. Copy writes joined text blocks. Branch stays a chrome stub. Clipboard write and the clock helpers live in `message-chrome.ts`. The assembled surface is pinned by `apps/web/tests/message-actions.e2e.ts` (cold-seeded history + aria golden); aria normalization collapses every clock shape to `{{clock}}`.

-Each turn's last settled content answer exposes copy and the event clock as soon as the row mounts; mid-turn content and Think-only nodes stay chrome-free; branch stays a stub. User and assistant clocks share the same day/year widening rules and refresh after midnight without a message mutation. Per-message paging remains a deferred footer seat in the package README.

 ## Decision
 
-**User bubbles prepend a date-aware local clock to the existing IconActions row; the last content-text assistant of each *settled* turn appends a copy / branch / clock row with `margin-top: 16px`; both seats stay visible whenever mounted and re-format at the next local midnight.**

-Both seats format `node.time` through `formatMessageClock`: same calendar day → `HH:mm`, earlier this year → `M月D日 HH:mm`, other years → `YYYY年M月D日 HH:mm`. `useCalendarDay` is a component-local day tick (timeout to the next local midnight) so memoized rows re-render when the calendar day changes without a new framework hook. `MessageItem` places the label before copy (figma `388:20051`). `ChatView` derives turn-tail seqs via `assistantActionsSeqs` and withholds a still-running turn through `withholdActionsTurn` (streaming `partial.turn`, else the first `runningCalls` turn; a bare `running` bit before the first step does not strip a prior settled seat). Selectors return a primitive turn so chunk storms do not re-render the list parent. `AssistantMarkdown` places the row after branch (figma `43:32997`) only when `streaming` is false, the event time is known, and the node has non-empty text content. Think-only nodes, mid-turn narration, an active turn's content, and the streaming tail omit the row. Copy writes joined text blocks. Branch stays a chrome stub. Clipboard write and the clock helpers live in `message-chrome.ts`. The assembled surface is pinned by `apps/web/tests/message-actions.e2e.ts` (owned cold seed with mid-turn narration text + aria golden that places copy only under the user bubble and the turn-tail `DONE`); aria normalization collapses every clock shape to `{{clock}}`.

-Each settled turn's last content answer exposes copy and the event clock as soon as the row mounts; mid-turn content, an active turn's content, and Think-only nodes stay chrome-free; branch stays a stub.

 Tool rows are slots too — the standalone tool ring (`ToolViewRegistry`/`ctx.toolviews`/outlet) is retired. The chat entry declares the keyed `'conversation.chat.toolview'` hole (session scope; the key space is runtime-open); its render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`. The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openFile`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '<tool>', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar). Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders).
 
-The todo surfaces are two registrations over that shape, both plain registrant plugins with `inject: ['slots', 'conversation']`. `TodoRow` takes the `'conversation.chat.toolview'` key `todo_write` and summarizes what the call attempted (`<done>/<total> 已完成 · <active item>` parsed from its args, falling back to the generic summary on malformed or wrongly-shaped model JSON, and keeping the generic dot for non-ok execution states so a cancelled call never reads as a completed update). `TodoDock` takes the `'conversation.input.dock'` list slot at `order: 10` — between Goal and Queue — and is the plan strip: it reads the host-computed `todos` projection via `useProjection` (standing plan: latest `todo/write` with no later `turn/start`) and renders `TodoPanel`, which takes the plain list, hides itself while the list is empty, and starts collapsed as a header of title plus `"<done>/<total> tasks · <n> in progress"` (status glyphs are the figma check / progress / dashed-pending set). The dock adapter owns the selection so the panel stays a pure function of its props; the standing list lives here rather than in the row so the row stays one line. Anything the input-zone composer chain hides (a `conversation.composer` takeover such as ui-question's) hides the whole dock, this strip included.

 Per-session UI state for selection and the active view lives in the declared chat store (`stores.ts` `createChatStore`); the InputHub owns the composer state machine and mirrors its draft into that store for persistence. Apply passes one store handle to the strict session subtree, chat view, and details registrations, so each session shares one instance and the framework owns its lifecycle. Components are pure: the framework standard kit supplies `useSession`/`sessionId`, global `useSessions`/`useWorkspaces`, and the input machine's `useInput`/`inputActions`; store faces and inject factories supply the remaining state and callbacks.

Subject: [PATCH 064/102] fix(tool-web): align fetch card truncation, drop view
 content copies, sync card docs

Address the code-review bot findings on the web result card:
- web_fetch's card truncated now derives from the shared renderFetchOutput
  helper, matching the effective truncation the model-facing text reflects
  (provider cap, source cut, or output cap), instead of the provider-only flag.
- Drop the redundant content copy from both web result views; a UI without the
  web capability falls back to the raw tool/result content. Narrow the TUI
  transcript view.content access accordingly.
- Set the result-state title from the call args (query/url) so a window-
  truncated replay keeps a title.
- Project meta from the seam result types rather than hand-rolled value types.
- Sync the card vocabulary across core tools README, docs/core-data-structures,
  the adding-a-tool cookbook, and the tool-web package README (both languages,
  re-recorded pairings); regenerate the cordis api-catalog and cordis-inspect
  snapshot; revise the Agent Note.

 One tag with a `kind` discriminant, not two tags. Both calls are web retrieval and a web frontend renders them with one component family (a retrieval card whose body differs by kind), so a shared `card` keeps every card consumer's switch to one added arm and lets the frontend branch on `kind` inside it. Two tags would force every present and future consumer to add two arms for what is one visual family. The `kind` values match the two tools' existing generic call-view `kind`s, so a call and its result read as the same category.
 
-`presentationMeta` is mandatory here, not a convenience. The structured result object a tool returns from `execute` does NOT reach a client over the wire — only the model-facing `render` text and, when declared, the `output.presentationMeta` JSON projected onto the `tool/result` event's `meta` do. Because the render text is lossy for `web_search`'s sources, projecting the sources through `presentationMeta` is the only faithful route to `{url, title?, snippet?, publishedAt?}` at the consumer. This mirrors the write/edit diff template (`packages/fs/tool-fs/src/diff.ts`): a `*MetaFromValue` projector feeds `output.presentationMeta`, and a `*MetaFromResult` narrower reads `result.meta` back with a defensive fallback to the generic card. `web_fetch`'s meta carries `url`/`statusCode`/`truncated` only; its body is already markdown in the result content, so it is not duplicated into meta.
+`presentationMeta` carries what render text cannot. The structured result object a tool returns from `execute` does NOT reach a client over the wire — only the model-facing `render` text and, when declared, the `output.presentationMeta` JSON projected onto the `tool/result` event's `meta` do. For `web_search` the meta is the ONLY faithful route to `{url, title?, snippet?, publishedAt?}`: the render collapses those fields into one lossy free-text line, so a consumer cannot reparse them. For `web_fetch` the meta is a smaller but real gain: `url`/`statusCode` are recoverable from the deterministic `Fetched <url> (HTTP <n>)` header line, but `truncated` is the effective truncation — provider cap, pre-conversion source cut, or the deployment's `fetchMaxOutputChars` output cap — which a client cannot recompute because it does not know that cap. The fetch card and the model-facing text derive `truncated` from one shared `renderFetchOutput(result, maxOutputChars)` helper, so the card never disagrees with the footer the model saw. This mirrors the write/edit diff template (`packages/fs/tool-fs/src/diff.ts`): a `*MetaFromValue` projector feeds `output.presentationMeta`, and a `*MetaFromResult` narrower reads `result.meta` back with a defensive fallback to the generic card. `web_fetch`'s body is already markdown in the result content, so it is not duplicated into meta.
 
-Each result view carries an optional `content?: ContentBlock[]` set to the model-facing result content. A UI without the `web` capability — including the TUI, whose transcript renderer has no `web` arm — renders that content through its existing generic/default path (`packages/ui/tui/src/components/transcript.ts`, `renderBody`'s `view.content ?? this.result?.content`), so the new tag needs no dedicated TUI arm and the TUI keeps compiling and rendering the text.
+Neither result view carries a `content` copy. A UI without the `web` capability — including the TUI, whose transcript renderer has no `web` arm — falls back to the raw `tool/result` content through its existing generic/default path (`packages/ui/tui/src/components/transcript.ts`, `renderBody` narrows to `view.card === 'generic' ? view.content : undefined` then falls back to `this.result?.content`). Copying the result content into the view would duplicate up to `fetchMaxOutputChars` characters on the same delivered frame for no gain (the same rejection the meta section applies to the fetch body), so the views omit it and the fallback path renders the identical text. Each view sets its result-state `title` from the call args (`args.query` / `args.url`) so a window-truncated replay that dropped the call head still has a title, the way write/edit reset title at result time.
 
 `presentResult` returns `undefined` (the generic card) on an error result and on absent or malformed `meta`, because presentation runs on replay of arbitrary logged results (possibly from an older schema) and must never throw. The narrowers validate every field defensively; an empty source list is valid meta, not malformed.
 
 ## Consequences
 
-The web frontend consumer is a separate later PR: this PR adds the contract arm and makes the two tools emit it, with no client-side rendering. Any existing `ToolResultView` consumer that switches exhaustively must add a `web` arm; the TUI does not switch exhaustively and needs none. `apiproxy`'s session schema already accepts any `card` string (`packages/host/apiproxy/src/api/sessions.schema.ts`), so the new view crosses the wire without a schema change.
+The web frontend consumer is a separate later PR: this PR adds the contract arm and makes the two tools emit it, with no client-side rendering. The one observable change is that the `web_search`/`web_fetch` `tool/result` events now persist a `data.meta` payload (the `web-fetch` keyless snapshot is refreshed accordingly); the model-facing render text and the TUI presentation are unchanged (the TUI falls back to the same result content). The assembled-application transcript snapshot that exercises a `web` card belongs to the consumer PR that renders it, delivered there. Any existing `ToolResultView` consumer that switches exhaustively must add a `web` arm; the TUI does not switch exhaustively and needs none. `apiproxy`'s session schema already accepts any `card` string (`packages/host/apiproxy/src/api/sessions.schema.ts`), so the new view crosses the wire without a schema change.

 采用一个标签加 `kind` 判别，而非两个标签。两个调用都是 web 检索，web 前端会用同一族组件渲染它们（一个检索卡片，正文按 kind 不同），因此共用一个 `card` 让每个 card 消费者的 switch 只需新增一个分支，并让前端在其内部按 `kind` 分岔。两个标签会迫使当前及未来每个消费者为本属同一视觉族的东西添加两个分支。这两个 `kind` 取值与两个工具既有的 generic 调用视图 `kind` 一致，因此一个调用与它的结果读起来是同一类别。

The design is pinned in [the render-intent-union Agent Note](../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md); the TUI and host/client runtime project this neutral vocabulary into their own views.

 Tools optionally own pure `presentCall()` and `presentResult()` render intents, so UIs do not special-case tool names:
 
 - Call views are `{ card: 'generic', title, kind?, rawInput?, content?, locations? }`, `{ card: 'terminal', title, description?, cwd? }`, or `{ card: 'diff', title, diffs, locations? }`.
-- Result views are `{ card: 'generic', title?, content? }`, `{ card: 'terminal', title?, output?, exitCode?, signal? }`, or `{ card: 'diff', title?, diffs }`.
+- Result views are `{ card: 'generic', title?, content? }`, `{ card: 'terminal', title?, output?, exitCode?, signal? }`, `{ card: 'diff', title?, diffs }`, or `{ card: 'web', kind: 'search' | 'fetch', title?, … }` (a completed web retrieval; the `kind` arms carry the structured search sources or the fetch summary, and a UI without the `web` capability falls back to the raw result content).
 
 Returning `undefined` selects generic fallback. Presenters depend only on their arguments and the durable result because UIs call them during live streaming and log replay. `output.presentationMeta(args, value)` derives JSON metadata for direct surface calls; that metadata persists with `tool/result` and returns to `presentResult`, while the canonical value itself remains execution-local and is never replayed. Nested Code dispatches do not compute metadata. `defineTool` soft-validates older logged arguments and falls back instead of crashing replay. `dsh-tool-bash` and `dsh-tool-fs` are the reference implementations; the [canonical-output Agent Note](../../../.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.md) owns the value/presentation split and the [render-intent Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md) owns card vocabulary.

Subject: [PATCH 067/102] fix(cli): declare the config-plane providers the
 shared base config mounts

The master merge moved the TUI composition into `apps/cli/config/base.cordis.yml`
and I carried the `settings-local` / `credentials-local` rows across without
adding them to the resolver manifest. Bare specifiers in an app config resolve
through that manifest's dependencies, so the whole tree failed to boot:

  dsh: plugin(s) failed to load: @deepseek-ai/dsh-settings-local,
  @deepseek-ai/dsh-credentials-local

which took every TUI PTY smoke with it. `verify-cordis-config` did not catch
it, so the boot smoke was the first signal.

Subject: [PATCH 068/102] test(ui-models): cover the failure paths, and share
 the one message reader
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The per-file coverage gate caught three uncovered paths in the error handling
this round added: the page banner for a failed row removal, the editor card's
transport-rejection catch, and `store.fail` itself.

Two of them are one click each — Remove with a rejecting write, Apply with a
rejecting write — so they are covered through the UI rather than by calling
the helpers directly. The third was a duplicated `error instanceof Error ?
error.message : String(error)` in two files; it becomes one exported
`messageOf`, which removes the branch from both call sites and gives the
fallback arm a home a direct unit test can reach (the lint rule forbids
rejecting a promise with a non-Error, so a rejection cannot exercise it).

Subject: [PATCH 069/102] fix(web-presenter): dim-Markdown web fallback,
 memoize fetch conversion, strip note residue

Route a `web` result card's raw-content fallback through the TUI's dim
Markdown path (render() only recognized `card: 'generic'` as markdown
content, so web fallback rendered as bare undimmed text).

Memoize renderFetchOutput per (result, maxOutputChars) so the registry's
twin output.render / output.presentationMeta calls on the same frozen
result run one HTML->markdown conversion instead of two.

Remove the trailing `</content>`/`</invoke>` protocol residue from both
sides of the web-result-card Agent Note and re-record the pairing.

+# Agent Note: Adapter-owned max-token defaults
+
+Status: implemented

+
+## Problem
+
+An LLM adapter could serialize an explicit `GenerateOptions.maxTokens`, but its Cordis configuration could not establish a reconstructable conversation default. Applying a fallback only inside provider serialization would make the wire request differ from the durable `request/header`; putting every provider's default in Agent Loop would instead transfer deployment and model policy into the provider-neutral driver.
+
+## Decision
+
+`LlmResolvedModelInfo.defaultMaxTokens` carries an optional adapter-configured per-request output cap for one exact provider/model route. `LlmService` validates it as a positive safe integer and materializes it into `LlmCallConfig.maxTokens` only when the caller omitted a value. Explicit request or Agent options therefore win without clamping.
+
+The agent loop continues to prepare calls before logging `request/header`, so an adapter default becomes a durable request fact before dispatch. Direct `LlmService.stream()` calls resolve the same default at the final adapter boundary. The field is a request default rather than a hard model output limit; adapters that preserve provider-owned defaults omit it.
+
+The native DeepSeek adapter exposes `maxTokens` in Cordis config with a 256,000-token default and maps the effective value to `max_tokens`. Its default context capacity is 1,000,000 tokens: both built-in V4 entries publish that exact capacity, while configured entries without capacity and unlisted pass-through ids inherit the same adapter-wide fallback.
+
+## Alternatives considered
+
+**Apply the default only in DeepSeek serialization.** Rejected because the provider wire would contain a model-visible value absent from the durable request header.
+
+**Set `AgentOptions.maxTokens` in every shipped application.** Rejected because applications would duplicate adapter deployment policy, direct LLM calls would behave differently, and selecting another provider would retain a DeepSeek-specific cap.
+
+**Represent 256,000 as a hard per-model maximum.** Rejected because the configured value is the desired request budget, not evidence that every configured endpoint rejects larger outputs. Explicit callers remain authoritative.
+
+**Leave the provider default in control.** Rejected for the native DeepSeek deployment because the product requires a stable 256,000-token conversation budget across compatible endpoints.
+
+## Consequences
+
+DeepSeek conversations send `max_tokens: 256000` by default, and the same value appears in the session request header. Deployments can change the adapter default through `llm-deepseek.config.maxTokens`; per-agent and per-request values override it. Other adapters retain their existing behavior until they intentionally publish `defaultMaxTokens`.
+
+The 256,000-token output budget reserves a large part of the one-million-token context on endpoints that pre-allocate requested output. Deployments whose gateway or model supports a smaller budget must lower `maxTokens`; the explicit configuration is preferable to an undocumented provider fallback.

+# Agent Note: 适配器持有的最大 token 默认值
+
+Status: implemented
+
+[English](2026-07-30-adapter-owned-max-token-defaults.md) | 中文
+
+## Problem
+
+LLM（大语言模型）适配器可以序列化显式的 `GenerateOptions.maxTokens`，但无法通过 Cordis 配置建立可重建的对话默认值。仅在提供方序列化中应用回退，会导致协议请求与持久 `request/header` 不一致；若将各提供方默认值都放进 agent loop（智能体循环），则会把部署与模型策略转移到提供方无关的驱动器中。
+
+## Decision
+
+`LlmResolvedModelInfo.defaultMaxTokens` 携带一条确切提供方／模型路由的可选单次请求输出上限，该值由适配器配置。`LlmService` 将其校验为正安全整数，并且仅在调用方省略值时才填入 `LlmCallConfig.maxTokens`。因此，显式请求值或 Agent 选项优先，且不会被自动调整。
+
+agent loop 仍在记录 `request/header` 前准备调用，因此适配器默认值会在分派前成为持久请求事实。直接调用 `LlmService.stream()` 时，也会在最终适配器边界解析同一默认值。该字段是请求默认值，而非模型输出硬上限；保留提供方持有默认值的适配器会省略它。
+
+原生 DeepSeek 适配器在 Cordis 配置中公开 `maxTokens`，默认值为 256,000 token，并将生效值映射为 `max_tokens`。其默认上下文容量为 1,000,000 token：两个内置 V4 配置项均公布这一精确容量；不含容量的已配置项和未列出的原样传递 id 则继承同一个适配器级回退值。
+
+## Alternatives considered
+
+**仅在 DeepSeek 序列化中应用默认值。** 不予采纳，因为提供方协议会包含持久请求 header 中缺失的模型可见值。
+
+**在每个已发布应用中设置 `AgentOptions.maxTokens`。** 不予采纳，因为应用会重复适配器部署策略，直接 LLM 调用的行为将不同，而且选择另一个提供方后仍会保留 DeepSeek 专用上限。
+
+**将 256,000 表示为每模型硬上限。** 不予采纳，因为配置值是所需请求预算，无法证明每个已配置端点都会拒绝更大的输出。显式调用方仍具有最终决定权。
+
+**由提供方默认值控制。** 对原生 DeepSeek 部署不予采纳，因为产品要求各兼容端点都采用稳定的 256,000 token 对话预算。
+
+## Consequences
+
+DeepSeek 对话默认发送 `max_tokens: 256000`，会话请求 header 中也会出现相同的值。部署可以通过 `llm-deepseek.config.maxTokens` 更改适配器默认值；每个 agent 和每次请求的值都会覆盖它。其他适配器会保留现有行为，直至主动公布 `defaultMaxTokens`。
+
+对于预分配请求输出的端点，256,000 token 的输出预算会占用 1,000,000 token 上下文中的很大部分。如果部署使用的 gateway 或模型仅支持较小预算，则必须调低 `maxTokens`；显式配置优于未记录的提供方回退值。

Persona belongs to `dsh-system-prompt`: an agent-scoped `deployment:persona` may shadow the global default.
 
 The cause is a TypeScript-enforced same-process input. An active `TurnCancellation` holder copies its discriminant into the runtime-only `AbortSignal.reason` and is retired before `turn/end` publication; the frozen `AbortSignal.reason` remains readable after that retirement. Only the loop reads the cause (`user`, `parent`, or lifecycle-only `disposed`) back off its own machine-private signal at settlement — there is no public reader, and a signal grants cooperating listeners no classification authority. Durable `turn/end` retains the coarse `{ kind: 'aborted' }` outcome; request provenance would require a separate durable event rather than overloading the terminal result.

 ## The seam
 
-`LlmAdapter` is the provider seam: subclass, implement `stream()`, and register one adapter instance with `ctx.llm.registerAdapter(providers, adapter)`. `GenerateOptions.provider` selects the registered adapter; `GenerateOptions.model` is passed to that adapter and need not be registered at lifecycle start. Duplicate provider routes fail atomically. Optional `providerRetryPolicy()` is captured per route with normal defaults, while `providerInfo()` and asynchronous `listModels()` feed `LlmService.listProviders()` / `listModels()` with detached selector metadata. That catalog is advisory rather than a request whitelist: the adapter remains authoritative and may accept unlisted model ids. One asynchronous `resolveModel()` query returns exact model identity plus optional correctness-sensitive context capacity and ordered model-owned reasoning ids with an optional deployment default; absent fields mean unavailable metadata or capability, not invalid catalog membership. The resolver receives optional cancellation and must settle promptly after abort. `LlmService.resolveModelInfo()` validates and detaches the aggregate. The service validates and materializes reasoning through `resolveCallConfig()` at the final adapter boundary, so direct calls cannot bypass unsupported-effort rejection; direct dispatch captures one registration before awaiting that resolution. The agent loop instead uses `prepareCall()` to keep the same registration across model resolution, durable header logging, and dispatch. Adapter lookup happens at the terminal continuation of the `llm/stream` waterfall, so a listener may short-circuit the call or route a mutable one-shot request before lookup. The `block-start` / `block-end` `index` correlation and the assembler together mean an adapter only has to emit well-formed chunks — block reassembly is not each adapter's problem. The consumer surface (`ctx.llm.stream()`) and the `llm/stream` waterfall are described in [architecture.md § Content blocks and streaming](../architecture.md#content-blocks-and-streaming-dsh-llm).

 The scoped-registration surface: `Agent.ctx` is the agent's scope context (`dsh-scope`, key = the agent) — register tools/sections/variables/listeners through it for that agent alone, all unwound on disposal. `agentEvents(ctx, agent)` is the fused dispatcher for ordinary agent-subject operations (carrier + injected subject in one move); its notification mode invokes every listener and contains both synchronous throws and returned-promise rejections. The registry lifecycle pair reuses one stable routing carrier. `assembleContextFor(agent)` builds the per-agent assembly context (`agent` + `scope` together). `installAgentLlmTarget(agentCtx, target)` snapshots a mutable provider/model/reasoning-effort selection during prompt assembly, applies the route to prompt variables, and applies the complete target to request routing for one step; an absent selected effort clears an inherited effort so the target uses adapter/provider defaults. `CreateAgentOptions.setup(agentCtx)` and `ResumeAgentOptions.setup(agentCtx)` compose a fresh or resumed agent's scoped world while both objects remain unpublished. Setup is trusted, composition-only same-process code: drive the agent only after creation resolves.

+`AgentOptions` supplies the initial provider/model route and an optional positive `maxTokens` output cap.

 - `ctx.agents.register(agent: Agent): () => void` — record an **already-constructed** agent. Disposed with the calling fiber.
 - Advanced ordered lifecycle: `enter(agent, owner): () => void` enforces `agent.id === agent.session.id`, performs the authoritative ID collision check, and inserts without announcing; `owner` explicitly records the live creator-agent relation (or `undefined` for a root), independently of durable session lineage. `announce(agent)` emits `agent/created` exactly once. A detach requested synchronously by a creation listener is deferred until that dispatch unwinds, and every detach checks the captured entry object, so a stale capability cannot delete a later same-ID replacement. The async factory uses this split; ordinary plugins use `register()`.

An explicit request or `AgentOptions.maxTokens` value wins and is serialized as `max_tokens`.
 
 The same exact-model result exposes ordered `off`, `high`, and `max` efforts under `reasoning` for every pass-through model when deployment policy permits thinking. `reasoningEffort` selects the deployment default and falls back to `high` when omitted. `agent/request` can replace it on each conversation step; the resolved value is logged in `request/header`. `high` and `max` enable thinking and serialize as the official top-level `reasoning_effort`; adapter-owned `off` instead serializes `thinking.type: disabled` and omits `reasoning_effort`. An unsupported value fails with `UNSUPPORTED_REASONING_EFFORT` before network I/O.

 Provider and model metadata is a discovery surface, not a routing whitelist. `registerAdapter()` still owns provider exclusivity and captures the adapter's retry policy for each route, while an adapter may accept model ids absent from `listModels()`; consumers must not reject a request because its model is unlisted.

An optional positive `initialize.maxTokens` becomes the request output cap of each SDK-created agent and its in-process descendants; invalid values reject initialization, while omission sends no cap and preserves provider defaults. A session accepts one in-flight prompt; overlap fails immediately, other sessions remain independent, and the session is reusable after settlement. `session.finished` reports that prompt's message-triggered turn outcome; later between-turn records still stream as `session.event` notifications but cannot replace the prompt status.

Subject: [PATCH 071/102] fix(web-presenter): align note with shipped TUI web
 arm, symbolize ref, guard branch

Rewrite the Agent Note's stale 'TUI has no web arm' claim to match the
web fallback branch this PR added to transcript.ts. Replace the hardcoded
line-number comment with a symbolic reference, and mark the web arm's
unreachable optional-chain undefined side with a reasoned v8 ignore for
the per-file 100% branch gate.

 `presentationMeta` carries what render text cannot. The structured result object a tool returns from `execute` does NOT reach a client over the wire — only the model-facing `render` text and, when declared, the `output.presentationMeta` JSON projected onto the `tool/result` event's `meta` do. For `web_search` the meta is the ONLY faithful route to `{url, title?, snippet?, publishedAt?}`: the render collapses those fields into one lossy free-text line, so a consumer cannot reparse them. For `web_fetch` the meta is a smaller but real gain: `url`/`statusCode` are recoverable from the deterministic `Fetched <url> (HTTP <n>)` header line, but `truncated` is the effective truncation — provider cap, pre-conversion source cut, or the deployment's `fetchMaxOutputChars` output cap — which a client cannot recompute because it does not know that cap. The fetch card and the model-facing text derive `truncated` from one shared `renderFetchOutput(result, maxOutputChars)` helper, so the card never disagrees with the footer the model saw. This mirrors the write/edit diff template (`packages/fs/tool-fs/src/diff.ts`): a `*MetaFromValue` projector feeds `output.presentationMeta`, and a `*MetaFromResult` narrower reads `result.meta` back with a defensive fallback to the generic card. `web_fetch`'s body is already markdown in the result content, so it is not duplicated into meta.
 
-Neither result view carries a `content` copy. A UI without the `web` capability — including the TUI, whose transcript renderer has no `web` arm — falls back to the raw `tool/result` content through its existing generic/default path (`packages/ui/tui/src/components/transcript.ts`, `renderBody` narrows to `view.card === 'generic' ? view.content : undefined` then falls back to `this.result?.content`). Copying the result content into the view would duplicate up to `fetchMaxOutputChars` characters on the same delivered frame for no gain (the same rejection the meta section applies to the fetch body), so the views omit it and the fallback path renders the identical text. Each view sets its result-state `title` from the call args (`args.query` / `args.url`) so a window-truncated replay that dropped the call head still has a title, the way write/edit reset title at result time.
+Neither result view carries a `content` copy. A UI that does not render the structured `web` card falls back to the raw `tool/result` content. The TUI does exactly this: it renders no structured web body, and its transcript renderer routes a `web` view's fallback content through the same dim Markdown path as a generic card's content (`packages/ui/tui/src/components/transcript.ts`, where both `render` and `renderBody` narrow the `generic` arm to `view.content` and give a `web` view the same `this.result?.content` fallback). Copying the result content into the view would duplicate up to `fetchMaxOutputChars` characters on the same delivered frame for no gain (the same rejection the meta section applies to the fetch body), so the views omit it and the fallback path renders the identical text.

 `presentResult` returns `undefined` (the generic card) on an error result and on absent or malformed `meta`, because presentation runs on replay of arbitrary logged results (possibly from an older schema) and must never throw. The narrowers validate every field defensively; an empty source list is valid meta, not malformed.

Subject: [PATCH 073/102] test(settings,apiproxy): cover the path-write and
 revision paths the wire reaches

The mutate seam's root-path ops, its non-array rejection, and the recursion
into an existing nested object were unexercised, as was the whole containment
side of the settings/document-updated fan-out and the before-snapshot repair
of a section a hand edit left non-object. The settings.mutate route had no
round trip at all: neither the client method nor the handler entry ran.

Subject: [PATCH 074/102] fix(tool-web): unexport renderFetchOutput so its memo
 stays behind the frozen path

renderFetchOutput has no external consumer: only formatFetchOutput and
fetchMetaFromValue call it, both through the registry, which deep-freezes
the result value. Exporting it let a hypothetical caller mutate a cached
input or the returned RenderedFetch and desync the card's truncated flag
from the model text. Drop it from the barrel and document that the memo
needs no defensive copy because every caller is internal and read-only.

From dceff19bd333cf7d64bc0bc900885ac20e12d7f1 Mon Sep 17 00:00:00 2001
From: Yichen Jiang <jyc132780208@sina.com>

Subject: [PATCH 075/102] fix(jsonrpc-agent): claim the renamed route in the
 persistent-tools replay catalog

The rename to deepseek-official reached cordis.snapshot.yml but not its
persistent-tools sibling, so the replay catalog no longer owned the route the
agent asks for. The SDK server then mounted the real adapter, which failed the
turn on a missing key. Re-records the six transcripts and the two diagnostics
cards that still carried the old route name.

Subject: [PATCH 076/102] test(web): re-record the goldens for master's
 context-injection disclosure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Merging master swapped the plain "▸ 上下文注入" button for the shared
DisclosureRow, which every conversation golden carrying an injected-context
row renders. The only change in all twelve files is that row.

+The agent loop continues to prepare calls before logging `request/header`, so the effective config and its adapter-default provenance become durable request facts before dispatch. Before the next `agent/request` waterfall, the loop removes marked fields from the proposal; exact-model resolution then materializes the current route's defaults again. A provider/model switch therefore cannot mistake a previous adapter's default for an explicit override, while explicit conversation values persist. Direct `LlmService.stream()` calls resolve the same default at the final adapter boundary. The field is a request default rather than a hard model output limit; adapters that preserve provider-owned defaults omit it.
 
 The native DeepSeek adapter exposes `maxTokens` in Cordis config with a 256,000-token default and maps the effective value to `max_tokens`. Its default context capacity is 1,000,000 tokens: both built-in V4 entries publish that exact capacity, while configured entries without capacity and unlisted pass-through ids inherit the same adapter-wide fallback.

+DeepSeek conversations send `max_tokens: 256000` by default, and the same value plus its adapter provenance appear in the session request header. Deployments can change the adapter default through `llm-deepseek.config.maxTokens`; per-agent and per-request values override it. Changing the route rematerializes the new exact adapter's default instead of carrying DeepSeek's derived value forward. Other adapters retain their existing behavior until they intentionally publish `defaultMaxTokens`.
 
 The 256,000-token output budget reserves a large part of the one-million-token context on endpoints that pre-allocate requested output. Deployments whose gateway or model supports a smaller budget must lower `maxTokens`; the explicit configuration is preferable to an undocumented provider fallback.

 对于预分配请求输出的端点，256,000 token 的输出预算会占用 1,000,000 token 上下文中的很大部分。如果部署使用的 gateway 或模型仅支持较小预算，则必须调低 `maxTokens`；显式配置优于未记录的提供方回退值。

Backends eagerly drain synchronous `session/event` notifications. `session/flush` barriers precede each request and top-level tool dispatch, then follow `turn/end` before another queued turn or idle observation. `SessionPersistence` stores `SessionEvent` directly and metadata in `SessionHeader`; JSONL defaults to checksummed Zstandard, while SQLite shares the contract ([decision](../.agents/notes/implemented/bug-fix/2026-07-21-semantic-session-checkpoints.md)).

 A `Session` is an **append-only log** of typed `SessionEvent`s — the single source of truth. The LLM message history is *derived* from the log (`deriveMessages()`), not stored separately. The event vocabulary derives from `SessionEventMap`:

 Every provider call that reaches a successful finish appends exactly one `assistant/message` completion anchor, including content-less calls and `max-tokens` finishes. The anchor records the assembled content as-is, retains exact chunk provenance (`[]` for a stream with no chunks), and includes usage when available; empty content stays out of derived message history.
 
-After `agent/request` returns a provider/model call config, the loop asks `ctx.llm.prepareCall()` to validate any adapter-owned reasoning effort and materialize its configured default under the active turn signal. The prepared call retains the exact adapter registration across this asynchronous resolution, `request/header` logging, and terminal dispatch, so HMR cannot mix one adapter's capability result with another adapter's request. The effective config is logged before dispatch, so a listener can change effort between steps without hidden request drift. A route with no registered adapter preserves the proposed config so an `llm/stream` listener can own and short-circuit it; unhandled terminal dispatch still fails with `NO_ADAPTER`. A new loop instance restores the last effort only when its initial provider/model route exactly matches the logged route; a route change discards that opaque model-owned ID and resolves the new model independently.
+After `agent/request` returns a provider/model call config, the loop asks `ctx.llm.prepareCall()` to validate adapter-owned fields and materialize configured reasoning-effort and output-token defaults under the active turn signal. The prepared call retains the exact adapter registration across this asynchronous resolution, `request/header` logging, and terminal dispatch, so HMR cannot mix one adapter's capability result with another adapter's request. The header records the effective config and which fields came from the adapter. Before the next waterfall, the loop removes those marked fields from the proposal so the current exact route rematerializes its own defaults; unmarked explicit settings persist across steps and route changes. A route with no registered adapter preserves the proposed config so an `llm/stream` listener can own and short-circuit it; unhandled terminal dispatch still fails with `NO_ADAPTER`. A new loop instance applies the same provenance rule when resuming.
 
 Plugin failure ends the current turn, not the loop. Only final adapter dispatch/iteration failures and terminal in-band error or aborted finishes enter `agent/request-error`; middleware, result processing, tools, and other extension failures close directly. Recovery receives the exact live error, immutable provider facts, immutable prior failures, the immutable retry policy of the adapter registration that served the request, and the turn signal after the failed step closes; the policy is absent if no final adapter served it. A handling listener returns `{ kind: 'retry' }`; the loop closes the failed turn with its error and opens one numbered retry turn without an intervening idle notification. Success clears the consecutive history, and an unhandled failure is terminal. AgentLoop owns one cancellation signal for the current admission or turn. An effective `cancel(cause)` clears pending work unless `keepInbox` is set and cooperatively aborts that signal; idle cancellation is a no-op. Durable `turn/end` records `aborted` for `user` and `parent`, while disposal records `disposed`; undispatched model tool calls receive synthetic `tool/call` and `ABORTED_BEFORE_DISPATCH` result pairs. The cancellation cause changes reporting, not how result context finalized after cancellation is handled. Disposal waits for signal-ignoring work before registry removal. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) owns the lifecycle and race contract.

Its optional `adapterDefaults` map marks effective `reasoningEffort` or `maxTokens` values materialized by exact-model resolution, allowing the next request proposal to distinguish them from explicit conversation settings. `foldRequestHeader()` selects the latest snapshot; legacy delta events and the removed `fallback` reason are rejected. See the [reconstructable-requests Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md).
 
 A `user/message` stores the complete `UserMessage` directly, including the identity created before routing or prompt admission. It renders its `content` verbatim whether it is a direct human prompt, a synthetic injection, or an admitted goal round; its typed `source` is the only channel that tells them apart and carries any domain-specific durable facts. `assistant/message`, `tool/result`, and `steering/message` likewise store complete message values. Turn execution remains enclosed by `turn/start` and `turn/end`, while an idle injection may append and flush a `user/message` between turns without running the model.

 `user/message` 会直接存储完整的 `UserMessage`，其中包括路由或提示词准入前创建的标识。无论它是直接人类提示词、合成注入，还是已准入的 Goal Round，都会原样呈现其 `content`；带类型的 `source` 是区分三者的唯一通道，并携带各领域专有的持久事实。`assistant/message`、`tool/result` 和 steering（中途引导）对应的 `steering/message` 也会存储完整的消息值。轮次执行仍由 `turn/start` 与 `turn/end` 包围，而空闲注入可以在轮次之间追加并刷新一条 `user/message`，无需运行模型。

 The plugin registers the single provider route `deepseek` together with its resolved `retryPolicy`. A request selects it with `provider: deepseek`; its `model` is passed through as the wire `model` string, so changing DeepSeek models does not require lifecycle-time registration. Omitting `models` advertises `deepseek-v4-flash` as `DeepSeek-V4-Flash` and `deepseek-v4-pro` as `DeepSeek-V4-Pro`, each with a 1,000,000-token context window; an explicit list replaces those defaults, while `models: []` advertises none. Catalog entries are exposed through `ctx.llm.listModels('deepseek')` for clients such as ACP editors and the Web selector, but remain advisory: unlisted model ids still pass through unchanged. An omitted entry name defaults to its id.
 
 `contextWindow` is optional per configured model and is not exposed through the advisory catalog. `ctx.llm.resolveModelInfo('deepseek', model).context` returns an exact model value first, then `defaultContextWindow` for an entry without capacity or an unlisted pass-through id. The adapter default is 1,000,000; pressure-sensitive plugins therefore get deployment-owned capacity without treating the model selector as authoritative. Registering another adapter for `deepseek` throws `LlmError('DUPLICATE_ADAPTER')`.
 
-`maxTokens` is the adapter-configured output cap for conversation requests and defaults to 256,000. Exact-model resolution exposes it as `defaultMaxTokens`; `LlmService` materializes that value into `GenerateOptions.maxTokens` before the agent loop writes `request/header`, so the wire request remains reconstructable. An explicit request or `AgentOptions.maxTokens` value wins and is serialized as `max_tokens`.

An explicit request or `AgentOptions.maxTokens` value wins and is serialized as `max_tokens`. The adapter does not clamp this request budget against `contextWindow`; deployments with a smaller context or provider output limit must configure a compatible `maxTokens`.
 
 The same exact-model result exposes ordered `off`, `high`, and `max` efforts under `reasoning` for every pass-through model when deployment policy permits thinking. `reasoningEffort` selects the deployment default and falls back to `high` when omitted. `agent/request` can replace it on each conversation step; the resolved value is logged in `request/header`. `high` and `max` enable thinking and serialize as the official top-level `reasoning_effort`; adapter-owned `off` instead serializes `thinking.type: disabled` and omits `reasoning_effort`. An unsupported value fails with `UNSUPPORTED_REASONING_EFFORT` before network I/O.

 该插件注册唯一提供方路由 `deepseek`，同时注册解析后的 `retryPolicy`。请求使用 `provider: deepseek` 选择该路由；其 `model` 会作为协议 `model` 字符串原样传递，因此更改 DeepSeek 模型不需要生命周期时注册。省略 `models` 会公布 `deepseek-v4-flash`（名称为 `DeepSeek-V4-Flash`）和 `deepseek-v4-pro`（名称为 `DeepSeek-V4-Pro`），两者的上下文窗口均为 1,000,000 token；显式列表会替换这些默认值，`models: []` 则不公布任何模型。Catalog 配置项通过 `ctx.llm.listModels('deepseek')` 公开给 ACP（Agent Client Protocol）编辑器和 Web 选择器等客户端，但仍只提供建议：未列出模型 id 仍原样传递。省略配置项 name 默认为其 id。
 
 `contextWindow` 对每个已配置模型都可选，不会通过建议 catalog 公开。`ctx.llm.resolveModelInfo('deepseek', model).context` 先返回精确模型值，再对不含容量的配置项或未列出原样传递 id 返回 `defaultContextWindow`。适配器默认值为 1,000,000；因此，压力敏感插件可以获得由部署决定的容量，不会将模型 selector 视为权威。为 `deepseek` 注册另一个适配器会抛出 `LlmError('DUPLICATE_ADAPTER')`。

boot() asserts over ctx.loader after awaiting the Loader, but the TUI renders
as soon as its own fiber starts: an /exit typed before the last entry settles
runs disposeRootAndExit, which takes the Loader service with the tree. The
assertions then read undefined and crashed the process with a TypeError over
an app that exited exactly as asked. The keyless personal-overlay PTY smoke
lost this race in roughly two of three runs.

Subject: [PATCH 080/102] fix(llm,settings): refuse post-disposal route
 replacement and teardown notifications

Two lifecycle holes the registry and the consumer helper left open.

`AdapterRegistrationHandle.replace` had no liveness guard: after the handle's
disposer ran, a replace put routes back into the registry with nothing left to
release them, so the adapter leaked permanently. `owned` being empty cannot
carry that fact, because `replace([])` is the legal empty-section state, so the
disposer records it explicitly.

`installSettingsSection`'s watcher lacked the guard its own disposer carries:
a stored change landing while the consumer unloads reached `onChange`, which
re-registers routes against a fiber whose resources are being released.

Also documents `withFileLock` in the atomic-write README (it claimed one
export), records the age-based lock takeover as a known limitation, and lists
ctx.settings and ctx.credentials in the architecture capability table.

Subject: [PATCH 081/102] test(web): drop the host-skill context row from the
 conversation goldens
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These goldens were recorded on a machine with personal skills under ~/.dsh and
~/.agents, so every one of them pinned a context-injection row a clean runner
cannot produce — which is why the browser lane failed on CI and passed
locally. master's scaffold fix confines skill-local's host-level roots to the
temp world; re-recording against it removes the row and nothing else.
seeded-history keeps its row: that scenario seeds the event itself.

GitHub created no workflow runs and no check runs for eaaec8173, leaving the
two required contexts waiting for a status that was never going to arrive.
Empty commit, identical tree — this only makes GitHub emit the pull_request
event again.

Subject: [PATCH 084/102] test(web): re-record plan-review golden for
 slash-free command row

The plan-review golden landed on master (63c477f14) recorded against the
old command-row rendering; this branch drops the slash and the argument
echo, so the approved-state transcript line changes accordingly.

 ## Decision
 
-**One readiness projection owns both Models and onboarding facts.** `ui-models` keeps a single store that joins `llm.providers({})`, redacted `settings.describe({})`, and batched `credentials.describe({refs})`. The onboarding projection selects the `deepseek-official` configurable-provider entry, resolves its `settingsNs` and `settingsPath`, reads the effective `apiKeyEnv`, and evaluates the matching credential descriptor. A configured literal `apiKey` secret sidecar is also ready, so compatibility configuration does not trigger a false prompt; a configured process-environment credential is ready and remains read-only.
+**One readiness projection owns both Models and onboarding facts.** `ui-models` keeps a single store that joins `llm.providers({})`, redacted `settings.describe({})`, and batched `credentials.describe({refs})`. The onboarding projection selects the `deepseek-official` configurable-provider entry owned by the `llm-deepseek` namespace and empty settings path, reads the effective `apiKeyEnv`, and evaluates the matching credential descriptor. A live route with the same provider id but no matching configurable-provider declaration is adapter-absent for onboarding. A configured literal `apiKey` secret sidecar is also ready, so compatibility configuration does not trigger a false prompt; a configured process-environment credential is ready and remains read-only.
 
 **The settings shell contributes navigation state, not provider policy.** `ui-settings` declares a root-scoped `settings.onboarding` list slot and tells registrants whether the current surface is the empty Hero. Its private `openSection(id)` callback opens the settings panel on one registered section. `ui-models` registers the DeepSeek overlay through the same declaration-aware deferred-registration path as its Models section, so plugin load order does not become a contract.
 
-**The prompt routes to the one credential editor.** A mounted, active adapter with a resolved, writable, unconfigured reference presents one action that opens Settings on Models. The existing DeepSeek setup card there exclusively owns the password input, `credentials.set({ref, value})`, write failures, and post-write refresh; the onboarding overlay never holds or submits a secret. An unavailable settings or credential capability keeps its deployment diagnostic and routes to the same page, while an absent adapter remains skipped because navigation cannot mount a Cordis plugin.

-**Unavailable states stay honest.** An absent configurable-provider entry suppresses the prompt because navigation cannot repair the composition. A present provider whose settings or credential capability cannot be resolved renders an actionable deployment diagnostic; a failed initial join names the connection problem and leads to the Models retry surface. Configure later dismisses the overlay for the current mounted surface and writes no completion fact. Settings, credential, provider-topology, and connection invalidations all refresh the shared join, so an external credential update closes an open prompt without a reload.

 ## Consequences
 
-The first-run flow now leads to the shipped adapter's existing editor without restarting: a keyless browser test boots the real Web composition under an isolated harness home, follows the prompt to Models, stores a generated key through that page into the home's `.env`, verifies no key reaches DOM, ARIA, or browser console output, and confirms the running page reports configured. Pure readiness and React tests pin literal, file, process-environment, missing-provider, missing-capability, navigation, cancellation, and external-invalidation behavior. The flow deliberately inherits the configuration plane's documented base limitations rather than adding local secret storage, redaction, or settings replacement workarounds.

 Rows are the *configured* providers (their profile resolves in the owning namespace); a whole-section provider whose key is not configured anywhere (the first-run DeepSeek posture) renders as its open setup card instead of a row, and the add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor is a hand-written card per adapter family: the primary field is a single **API key** input — the page never asks for an environment-variable name; a typed key stores **write-only** through `credentials.set` under the profile's reference, deriving `<ROUTE>_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. The collapsed 自定义设置 fold carries the curated extras — `baseURL` for both families (the deepseek placeholder shows the public endpoint), plus `reasoningEffort` (deepseek) or `reasoning` (pi-ai); every other profile field stays owned by `settings.yaml`. A row is deletable only when the user layer alone carries it (removal restores the composition base).
 
-The first-run overlay projects `deepseek-official` readiness from that same joined snapshot. A configured literal `apiKey` secret sidecar or configured credential reference suppresses the prompt, including a read-only launch-environment credential. A mounted adapter with a missing writable reference shows one action that opens Settings on the Models section, whose existing setup card exclusively owns key input and `credentials.set`; the overlay never holds a secret. An absent adapter is skipped because browser navigation cannot mount Cordis plugins, while an unusable settings or credential capability produces a deployment diagnostic with the same route to Models.
+The first-run overlay projects `deepseek-official` readiness from that same joined snapshot. It recognizes the official adapter through its `llm-deepseek` configurable-provider declaration, so an undeclared live route with the same provider id is not treated as repairable configuration. A configured literal `apiKey` secret sidecar or configured credential reference suppresses the prompt, including a read-only launch-environment credential. Only a mounted adapter with a missing writable reference shows the action that opens Settings on the Models section, whose existing setup card exclusively owns key input and `credentials.set`; the overlay never holds a secret. An absent adapter, inactive route, failed join, read-only deployment, or unusable settings or credential capability is skipped so onboarding cannot block the rest of the product; the Models page remains the diagnostic surface.
 
 Every edit lands as `settings.mutate` path ops against the stored section — a set per changed field, an unset per cleared one, and a single unset for a deleted row. The page only ever holds the REDACTED descriptor, so it names the fields it can see rather than rebuilding a section: a stored literal secret it never received is mentioned by no op and survives. Each write carries the `revision` the card opened at, so a concurrent write from another tab or an external `settings.yaml` edit is refused as `settings-conflict` and the card asks the user to reopen instead of replaying its stale snapshot. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.

 行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；密钥未在任何地方配置的整分节提供方（DeepSeek 的首次运行姿态）会渲染为其展开的设置卡片而非一行，「新增」流程则是一张承载休眠目录提供方选择框的卡片——裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器是每个适配器家族各一张的手写卡片：主字段是单独一个 **API 密钥**输入框——页面从不询问环境变量名；键入的密钥经 `credentials.set` 以**只写**方式存入 profile 的引用之下，profile 没有引用时便派生 `<ROUTE>_API_KEY`，pi-ai profile 会把这次派生记录为 `apiKeyEnv`，因此 `settings.yaml` 从不携带密钥值。收起的「自定义设置」折叠区承载精选的额外字段——两个家族都有 `baseURL`（deepseek 的占位符显示公共端点），另加 `reasoningEffort`（deepseek）或 `reasoning`（pi-ai）；其余每个 profile 字段仍归 `settings.yaml` 所有。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。
 
-首次使用浮层从同一个联接快照得出 `deepseek-official` 的就绪状态。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，浮层就不再显示，其中包括来自启动环境且只读的凭据。适配器已挂载、引用可写但尚未配置时，浮层只显示一个操作按钮，用于打开「设置」的 Models 分区；密钥输入和 `credentials.set` 仅由该分区已有的设置卡片负责，浮层绝不持有 secret。适配器缺失时直接跳过，因为浏览器导航无法挂载 Cordis 插件；设置或凭据能力不可用时则显示部署诊断，并提供同一个前往 Models 的入口。
+首次使用浮层从同一个联接快照得出 `deepseek-official` 的就绪状态。它通过 `llm-deepseek` 的可配置提供方声明识别官方适配器，因此不会把同一提供方 ID 下没有相应声明的存活路由视为可通过配置修复。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，浮层就不再显示，其中包括来自启动环境且只读的凭据。只有适配器已挂载、引用可写但尚未配置时，浮层才显示一个操作按钮，用于打开「设置」的 Models 分区；密钥输入和 `credentials.set` 仅由该分区已有的设置卡片负责，浮层绝不持有 secret。适配器缺失、路由未激活、联接失败、部署只读、设置能力不可用或凭据能力不可用时均跳过，以免首次使用引导阻塞产品的其他部分；Models 页仍是诊断界面。
 
 每一次编辑都以 `settings.mutate` 的路径 op 落到已存分节上——每个变更字段一条 set、每个清空字段一条 unset、删除整行则是单独一条 unset。页面自始至终只持有**脱敏后**的 descriptor，因此它点名自己看得见的字段，而不是重建分节：一个它从未收到过的已存字面机密不会被任何 op 提及，也就得以留存。每次写入都携带该卡片打开时的 `revision`，因此来自另一个标签页或对 `settings.yaml` 的外部编辑所产生的并发写入会以 `settings-conflict` 被拒绝，卡片会请用户重新打开，而不是把自己的陈旧快照重放上去。页面加载完成后会在推送的失效事件（`settings/changed`、`credentials/changed`、`models/changed` 与 `connection/reset`）上重拉，因此外部的 `settings.yaml` 编辑、第二个标签页或 settings 新生的路由都无需轮询即可收敛。

Subject: [PATCH 086/102] feat(web): wire session-telemetry-otel into the dsh
 web composition

Mount the existing telemetry seam + OTel logs backend in the web/headless
config tree so every session-log event streams to an OTLP/HTTP collector:

- telemetry-otel row: url defaults to the standard local OTLP endpoint,
  DSH_TELEMETRY_OTLP_URL overrides; 10s batch cadence; exporter/processor
  values bound the shutdown drain to ~1s against an unreachable collector
  (timeoutMillis doubles as the retry deadline, single-batch drain).
- DSH_TELEMETRY_DISABLED opt-out: AppCLIEntry patches the row disabled
  before boot (config alone cannot disable a row, and exporter.url
  validation is load-time fail-loud).

Boot the real dsh web tree against an in-test OTLP/HTTP collector and a
mock LLM server, drive one turn over /api, then SIGINT. Asserts the wire:
OTLP JSON structure and resource identity, both instrumentation scopes,
ledger event coverage in seq order, prompt fidelity in the exported body,
the first-of-step chunk projection, and the ops shutdown marker arriving
through the exit drain.

Subject: [PATCH 088/102] ci: disable session telemetry in all GitHub workflows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

apps/cli/cordis.yml now bakes in the production OTLP endpoint; CI boots of
the web composition (e2e, snapshots, built smokes) must not stream test
sessions there. DSH_TELEMETRY_DISABLED=1 at the workflow level disables
the telemetry row before its load-time url validation; the telemetry e2e
still runs — it overrides the variable to empty for its child process and
points DSH_TELEMETRY_OTLP_URL at its in-test collector.

Subject: [PATCH 090/102] docs: Agent Note for the default web telemetry mount

Pins the deployment rulings: default-on with the production endpoint,
DSH_TELEMETRY_OTLP_URL / DSH_TELEMETRY_DISABLED env seams, 10s cadence,
the ~1s exit-drain parameter set, CI isolation, and the explicit
follow-ups (redaction, identity resource, TUI adoption, metrics).

+# Agent Note: Default session-telemetry mount (OTel reporting) in the dsh web composition
+
+Status: implemented
+
+English | [中文](2026-07-31-web-telemetry-default-mount.zh.md)
+
+## Problem
+
+The telemetry seam and OTel backend ([revival Note](2026-07-23-session-telemetry-otel-revival.md)) had never been wired into any deployment composition since completion: no roster row, no switch, no cadence ruling, and zero observability over user sessions for the internal deployment. A deployment decision was needed: which surfaces report, to where, on what cadence, how to opt out, and how CI stays isolated.
+
+## Decision
+
+The shared web/headless composition (`apps/cli/config/web.cordis.yml`) mounts the `telemetry-otel` row by default with a baked-in production endpoint; this is the **internal-testing deployment stance** — reporting is on when an endpoint exists, and users opt out through the environment. The TUI composition stays unmounted (its normal exit path never disposes the root fiber, so mounting before that drain semantic is resolved would misreport every clean TUI exit as a crash).
+
+| Ruling | Value | Rationale |
+|---|---|---|
+| Mount surface | web.cordis.yml insert block (web + headless share it) | Both surfaces boot the same tree; the TUI deliberately stays out |
+| Endpoint | `DSH_TELEMETRY_OTLP_URL`, default `https://harness-telemetry.deepseeksvc.com/v1/logs` | Internal collector; the env override serves local/dev runs |
+| Opt-out switch | any non-empty `DSH_TELEMETRY_DISABLED` (including `0`/`false`) disables | A privacy switch prefers off-by-mistake over on-by-mistake; a row can only be disabled at AppCLIEntry's patch layer (config has no disable semantic, and the switch must precede the load-time `exporter.url` validation) |
+| Cadence | `processor.scheduledDelayMillis: 10000` (10s/batch) | Streaming while the session runs, never exit-time-only; a crash loses at most the last unexported interval |
+| Exit-drain bound | `exporter.timeoutMillis: 1000` + `maxExportBatchSize: 2048` (== maxQueueSize) + `exportTimeoutMillis: 1500` | Dispose must release within ~1s against an unreachable collector: timeoutMillis doubles as the per-attempt socket timeout and the retry deadline (1s effectively disables the SDK's 5-try backoff), and aligning batch size with the queue cap makes the drain a single batch; SDK defaults can stall 40s+ |
+| Compression | `compression: gzip` | Event bodies carry full content; cross-datacenter bandwidth |
+| CI isolation | top-level `env: DSH_TELEMETRY_DISABLED: '1'` in all 8 GitHub workflows | Every CI channel that boots the web composition (e2e/snapshot/built smokes) must not stream test sessions to the production endpoint |
+
+The keyless integration test `apps/cli/tests/telemetry-web.e2e.ts` pins the deployment-level behavior: an in-test OTLP collector plus a mock LLM server, a real `dsh web` boot, asserting ledger coverage, seq monotonicity, the first-of-step chunk projection, and the ops `shutdown` marker arriving through the SIGINT drain.
+
+## Alternatives considered
+
+**No default mount; deployments add the row themselves (continuing the SDK stance).** Rejected for this stage: this repo's web/headless composition IS the internal deployment, and default-on reporting is that deployment's product requirement; the SDK stance survives in the seam packages (unmounted = nothing leaves).
+
+**A config field instead of an env patch for the switch.** Infeasible: cordis rows have no config-level disable semantic, and `exporter.url` validation fails loud at plugin construction, so the switch must take effect before the Loader — AppCLIEntry's patch layer is the only seat.
+
+**A `Promise.race` timeout backstop around exit.** Deferred: the parameter set already bounds the worst-case drain to ~1.5-3s (typically <100ms), measured SIGINT-to-exit 110ms-1.1s; the unbounded drip-feed-response risk stays under observation, and on real evidence the race lands inside the backend's `shutdown()` (never the coordinator — that would decide loss semantics for every backend).
+
+## Consequences
+
+- A developer running `dsh web` without a local collector POSTs to the production endpoint every 10s (silent failure when unreachable; no OTel diag logger is registered); local development sets `DSH_TELEMETRY_DISABLED=1` or points `DSH_TELEMETRY_OTLP_URL` locally.
+- **No redaction rule is mounted yet**: exports are the raw captured copy (full user/assistant message text, tool arguments and results, the system prompt, the local `session.cwd` path). Crossing a trust boundary requires `telemetry/record` rules first — the redaction rule, identity Resource attributes (hostname / anonymous user id / surface), TUI adoption, and the usage-metrics track are the explicit follow-ups of this decision.
+- Test rigs reusing this tree (e.g. `apps/web/tests/scaffold.ts`) must explicitly disable the row, or fixture sessions stream to whatever collector the environment happens to name.

+# Agent Note: dsh web 组合默认挂载会话遥测（OTel 上报）
+
+Status: implemented
+
+[English](2026-07-31-web-telemetry-default-mount.md) | 中文
+
+## Problem
+
+遥测 seam 与 OTel backend（[revival Note](2026-07-23-session-telemetry-otel-revival.zh.md)）自完成以来从未接入任何部署组合：没有 roster 行、没有开关、没有节奏口径，内部部署对用户会话零可观测。需要一个部署决策：哪些 surface 上报、报到哪、什么节奏、怎么关、CI 怎么隔离。
+
+## Decision
+
+Web/headless 共享组合（`apps/cli/config/web.cordis.yml`）默认挂载 `telemetry-otel` 行，内置生产 endpoint；这是**内部测试期的部署立场**——有 endpoint 就报，用户可经环境变量退出。TUI 组合暂不挂载（其正常退出路径不经根 fiber dispose，drain 语义未解决前接入会把每次正常退出误报为 crash）。
+
+| 决策项 | 取值 | 理由 |
+|---|---|---|
+| 挂载面 | web.cordis.yml 的 insert 块（web + headless 共享） | 两 surface 同一棵树；TUI 明确不挂 |
+| endpoint | `DSH_TELEMETRY_OTLP_URL`，缺省 `https://harness-telemetry.deepseeksvc.com/v1/logs` | 内部 collector；env 覆盖供本地/联调 |
+| 退出开关 | `DSH_TELEMETRY_DISABLED` 非空（含 `0`/`false`）即关 | 隐私向开关取「宁关勿误开」；行级 disable 只能在 AppCLIEntry 的 patch 层做（config 无 disable 语义，且必须先于 `exporter.url` 的加载期校验生效） |
+| 上报节奏 | `processor.scheduledDelayMillis: 10000`（10s/批） | 流式回流，非退出才报；崩溃至多丢最后一个未导出间隔 |

+
+集成测试 `apps/cli/tests/telemetry-web.e2e.ts`（keyless）钉住部署级行为：测试内 OTLP collector + mock LLM，真启动 `dsh web`，断言 ledger 覆盖、seq 单调、chunk 首条投影、以及 SIGINT drain 后 ops `shutdown` 标记到达。
+
+## Alternatives considered
+
+**默认不挂载，部署方自行加行（SDK 立场的延续）。** 否决于当前阶段：本仓的 web/headless 组合就是内部部署本身，「上报默认开」是这个部署的产品要求；SDK 立场仍由 seam 包保持（不挂 = 零外发）。
+
+**开关做成 config 字段而非 env patch。** 不可行：cordis 行没有 config 层的 disable 语义，且 `exporter.url` 校验在插件构造期 fail-loud，开关必须在 Loader 之前生效——AppCLIEntry patch 层是唯一落点。
+
+**退出时 `Promise.race` 兜底超时。** 暂缓：参数组合已把最坏 drain 压到 ~1.5-3s（典型 <100ms），实测 SIGINT→退出 110ms-1.1s；drip-feed 慢滴响应的无界等待风险留观，出现实证再在 backend `shutdown()` 内加 race（不放 coordinator——那会替所有 backend 决定丢失语义）。
+
+## Consequences
+
+- 无本地 collector 的开发者跑 `dsh web` 会对生产 endpoint 每 10s 发一次 POST（联不通则静默失败，OTel diag logger 未注册）；本地开发设 `DSH_TELEMETRY_DISABLED=1` 或 `DSH_TELEMETRY_OTLP_URL` 指本地。
+- **当前零脱敏规则挂载**：导出即原始捕获副本（用户/助手消息全文、工具参数与结果、system prompt、`session.cwd` 本地路径）。跨信任边界前必须挂 `telemetry/record` 规则——脱敏规则、身份 Resource 维度（hostname/匿名 user id/surface）、TUI 接入、使用数据 metrics 轨四件是本决策明确的后续工作。
+- 复用这棵树的测试载具（如 `apps/web/tests/scaffold.ts`）须显式关停该行，否则 fixture 会话会流向 env 里碰巧存在的 collector。

- resolveTelemetryPatch: extracted pure switch resolution (unit-tested);
  fails loud when DSH_TELEMETRY_DISABLED is set but the row is absent, and
  documents that ANY non-empty value (including '0'/'false') disables.
- runHeadless: SIGINT/SIGTERM now dispose the tree before exit so the
  telemetry tail and shutdown marker drain (Node's default signal exit
  skips disposal).
- web.cordis.yml: explicit maxQueueSize beside maxExportBatchSize (the
  single-batch drain invariant no longer leans on an SDK default), comment
  covers exportTimeoutMillis's role and links the Agent Note.
- apps/web scaffold: disable telemetry-otel — fixture sessions must never
  leave the process.
- apps/cli README (en/zh + pairing): document the default endpoint, both
  env seams, and the no-redaction disclosure.

 `DSH_TOOLS_MODE` selects the tool presentation mode for the whole Web/headless process: `native` (the schema default when unset), `code` (the `run_code`-only Code Mode wire), or `both`; any other value fails loud at boot through the `dsh-tools` config schema. It is a TEMPORARY seam — process-wide because Loader composition is static — and is removed once the web UI owns per-session tool-mode selection; the TUI surface ignores it (its config tree pins its own mode).
 
+The Web/headless composition reports session telemetry by default: every session-log event streams as OTLP/HTTP log records to `https://harness-telemetry.deepseeksvc.com/v1/logs` on a 10-second batch cadence. `DSH_TELEMETRY_OTLP_URL` points the exporter at a different collector; setting `DSH_TELEMETRY_DISABLED` to ANY non-empty value — including `0` or `false` — disables the row before it loads (a privacy switch prefers off-by-mistake over on-by-mistake). No redaction rule is mounted in this composition yet: exported records are the raw captured copy, including message text, tool arguments and results, and the session's working-directory path. The deployment rulings live in the [web-telemetry-default-mount Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-telemetry-default-mount.md); the TUI surface does not report.

The row moves from web.cordis.yml to base.cordis.yml, so the TUI reports
too (its exit paths already drain: disposeRootAndExit on normal exit, root
dispose before the /resume execve). The TUI launcher applies the same
resolveTelemetryPatch opt-out, judged against the tree actually booting via

failed by a switch with nothing to disable. The TUI keyless smoke disables
telemetry in its child env; README (en/zh) and the Agent Note pair updated
to the every-surface stance.

 ## Decision
 
-The shared web/headless composition (`apps/cli/config/web.cordis.yml`) mounts the `telemetry-otel` row by default with a baked-in production endpoint; this is the **internal-testing deployment stance** — reporting is on when an endpoint exists, and users opt out through the environment. The TUI composition stays unmounted (its normal exit path never disposes the root fiber, so mounting before that drain semantic is resolved would misreport every clean TUI exit as a crash).
+The shared `dsh` core (`apps/cli/config/base.cordis.yml`) mounts the `telemetry-otel` row by default with a baked-in production endpoint, so every surface — TUI, web, and headless — reports; this is the **internal-testing deployment stance** — reporting is on when an endpoint exists, and users opt out through the environment. Each surface's exit path drains the queue: web/headless dispose on SIGINT/SIGTERM (headless gained those handlers in this change), and the TUI's normal exit runs `disposeRootAndExit` (root dispose, 5s bounded — above the ~1s drain ceiling configured here) while its `/resume` handoff disposes the root before `execve`.
 
 | Ruling | Value | Rationale |

-| Mount surface | web.cordis.yml insert block (web + headless share it) | Both surfaces boot the same tree; the TUI deliberately stays out |

 | Endpoint | `DSH_TELEMETRY_OTLP_URL`, default `https://harness-telemetry.deepseeksvc.com/v1/logs` | Internal collector; the env override serves local/dev runs |
 | Opt-out switch | any non-empty `DSH_TELEMETRY_DISABLED` (including `0`/`false`) disables | A privacy switch prefers off-by-mistake over on-by-mistake; a row can only be disabled at AppCLIEntry's patch layer (config has no disable semantic, and the switch must precede the load-time `exporter.url` validation) |
 | Cadence | `processor.scheduledDelayMillis: 10000` (10s/batch) | Streaming while the session runs, never exit-time-only; a crash loses at most the last unexported interval |

 ## Consequences
 
 - A developer running `dsh web` without a local collector POSTs to the production endpoint every 10s (silent failure when unreachable; no OTel diag logger is registered); local development sets `DSH_TELEMETRY_DISABLED=1` or points `DSH_TELEMETRY_OTLP_URL` locally.

 ## Decision
 
-Web/headless 共享组合（`apps/cli/config/web.cordis.yml`）默认挂载 `telemetry-otel` 行，内置生产 endpoint；这是**内部测试期的部署立场**——有 endpoint 就报，用户可经环境变量退出。TUI 组合暂不挂载（其正常退出路径不经根 fiber dispose，drain 语义未解决前接入会把每次正常退出误报为 crash）。

+# Agent Note: Full client copy rollout onto the typed locale seat, and the non-translation boundary
+
+Status: implemented
+
+English | [中文](2026-07-30-client-locale-full-rollout.zh.md)
+
+## Problem
+
+After the typed locale standard seat landed (`locale:` on register → framework-injected typed `t`), only four early adopters rode it; every other client package still shipped hardcoded, mixed-language literals. Migrating the rest required mechanisms and boundary decisions the early adopters never touched: how registration-time text (nav rows, view-tab labels) refreshes on a language switch; how the zero-cordis ui-primitives atoms receive copy; and which strings deliberately stay untranslated — an unrecorded boundary invites a future agent to "complete" the localization.
+
+## Decision
+
+**Registration-time text rides a label thunk.** A list registration's `label` accepts `SlotLabel = string | (() => string)`; owners projecting ledger rows resolve through `resolveSlotLabel` (never reading `options.label` raw) and make the read point follow the locale revision (outlets subscribe to the revision themselves; off-ledger projections such as the ui-settings nav fold the revision into their cache key and subscribe to both sources). Thunks evaluate per read, so a language switch causes zero ledger churn — no re-registration, versions stay put, and every `locale/change` re-registration wiring is deleted.
+
+**Component copy rides the standard `t` seat; deep children take `t` as a plain prop** typed `XxxProps['t']`. The dictionary canon is unchanged: `zh satisfies Record<string, string>` is the key source and `en satisfies Record<XxxKey, string>` locks bilingual balance.
+
+**Zero-cordis atoms (ui-primitives) take copy as props**: `labels` on `TerminalBlock`/`JsonTree`, `copyLabel`/`copiedLabel` on `CodeBlock`, `codeLabels` on `MarkdownText`, `truncatedLabel` on `JsonBlock`, `label` on `ConnectionBanner`, `closeLabel` on `Modal` — defaults are the previous hardcoded strings, so a consumer passing nothing renders byte-identical output. Localized plugins pass dictionary-driven labels from their own `t` seat; call sites passing object props memoize them on the `t` identity (`MarkdownText` caches its component table on the `codeLabels` identity).
+
+**The non-translation boundary (deliberate decisions, not debt):**
+
+- **Error/failure strings stay English**: client-authored fallbacks (`command failed`, plan-toggle failures), RpcError messages, and wire `error.message (code)` pass-throughs render verbatim.
+- **Design literals stay out of the dictionaries**: tool-row variant titles (Think/Bash/…), SYSTEM/USER-style kind badges, the Plan chip wordmark, the whole StatsLine — identical in both languages.
+- **ui-trajectory is deferred wholesale** (a developer inspection surface, terminology-dense, ruled separately).
+- **Boot copy stays hardcoded** (AppRoot renders before the locale service exists).
+
+**Derivation layers stay pure; localization happens at render.** ui-workspace's `relativeTime` returns structured `{unit, n}` composed with dictionary templates by the renderer; blank sessions and the Ungrouped bucket keep their stored titles, with the renderer substituting localized copy off the `blank` flag / absent `workspaceId`; **blank rows are excluded from search entirely** (a bilingual display title cannot match a single-language query stably). Dates use no Intl: format templates live in the dictionaries (message clock `clock.md`/`clock.ymd`, workspace hover `date.ymd`) and the formatters take `t` as a parameter, staying pure.
+
+**Test and e2e doctrine**: `makeTranslate(...dicts)` (dsh-client-test-runtime) mirrors the service lookup chain (first-dict-wins, key fallback, `{name}` interpolation); component specs stub the `t` seat with it, typed against real props seats. Web e2e uniformly opens through `newEnglishPage` (pins `dsh.locale=en` before boot) and the built-boot snapshot pins the same — goldens are immune to localization migrations; the settings language-switch scenario deliberately bypasses the helper to cover the zh default.
+
+The "apply layer subscribes to `locale/change` and re-registers for fresh labels" mechanism in the [settings/locale/theme layering note](../../proposed/architecture/2026-07-25-client-settings-locale-theme.md) is superseded by this decision (thunk + revision lifecycle).
+
+## Alternatives considered
+
+- **Keep labels as strings and re-register on switch** (the early adopters' original shape): boot already registers once per package, and `locale/change` listeners re-registering amplifies into a storm; ledger version churn also busts every version-keyed projection cache. Thunks move the refresh cost to read points that already follow the revision.
+- **A locale context/injection channel for ui-primitives**: breaks the zero-cordis boundary (atoms would depend on the runtime) and drags unlocalized consumers (ui-trajectory) along. Props let each consumer decide independently.
+- **Error strings in the dictionaries**: the error surface is a debugging surface — verbatim English is what gets searched and compared in reports; wire pass-throughs are untranslatable anyway, and half-translation manufactures mixed-language text.
+- **`toLocaleString()`/Intl for dates**: follows the browser/OS language, not the app locale, guaranteeing mixed text after a switch; the dictionary templates are tiny and isomorphic to the message clock.
+- **Blank rows matching search (against localized or stored titles)**: either choice yields "visible but unfindable" in one language; placeholder rows carry no information, so whole-row exclusion is the stable semantic.
+
+## Consequences
+
+- A language switch refreshes the whole UI instantly with zero re-registration; adopting a new package is three steps (dictionary + declare-merge + `locale: NS`), no hand-written glue.
+- Cost: list-label consumers must know `resolveSlotLabel` (a raw `options.label` read can now hold a function); the `SlotLabel` type catches most misuse statically.
+- ui-primitives' Chinese defaults still render Chinese under the English locale **until a consumer passes labels** — the unmigrated JsonTree consumer (ui-trajectory) showing its English defaults happens to match that package's all-English status quo.
+- Pinning e2e to English means the zh default is covered mainly by package-level component specs and the settings language-switch scenario; browser e2e no longer asserts zh copy.

+# Agent Note: client 文案全量接入 typed locale 席位与不翻译边界
+
+Status: implemented
+
+[English](2026-07-30-client-locale-full-rollout.md) | 中文
+
+## Problem
+
+typed locale 标准席位（`locale:` 注册声明 → 框架注入强类型 `t`）落地后，只有四个先行包接入；其余 client 包的文案仍是硬编码的中英混杂字面量。全量迁移需要几个先行包没有触及的机制与边界决定：注册期文本（导航行、视图 tab 的 label）在语言切换时如何刷新；zero-cordis 的 ui-primitives 原子组件如何拿到文案；哪些字符串**刻意不**本地化——没有记录的边界会诱使后来者"补完"翻译。
+
+## Decision
+
+**注册期文本走 label thunk。** ui-slots 的 list 注册项 `label` 接受 `SlotLabel = string | (() => string)`；owner 投影 ledger 行时必须经 `resolveSlotLabel` 解析（不裸读 `options.label`），并让读取点跟随 locale revision（outlet 自身订阅 revision；ledger 外的投影如 ui-settings 导航把 revision 并进缓存键、订阅双源）。thunk 每次读取时求值，语言切换零 ledger churn——没有重注册、version 不动，`locale/change` 重注册接线全部删除。

+**组件文案走标准 `t` 席位；深层子组件用 prop 下传**，类型写 `XxxProps['t']`。字典规范形态不变：`zh satisfies Record<string, string>` 为 key 源、`en satisfies Record<XxxKey, string>` 锁双语平衡。
+
+**zero-cordis 原子组件（ui-primitives）文案 props 化**：`TerminalBlock`/`JsonTree` 的 `labels`、`CodeBlock` 的 `copyLabel`/`copiedLabel`、`MarkdownText` 的 `codeLabels`、`JsonBlock` 的 `truncatedLabel`、`ConnectionBanner` 的 `label`、`Modal` 的 `closeLabel`——默认值即原硬编码字符串，不传 props 的消费者渲染逐字节不变。已本地化的插件从自己的 `t` 席位传字典驱动的 label；传对象 props 的调用点按 `t` 身份 memo（`MarkdownText` 的组件表按 `codeLabels` 身份缓存）。
+
+**不翻译边界（刻意决定，不是欠账）：**
+
+- **错误/失败类字符串一律英文**：client 自产的兜底串（`command failed`、plan 切换失败）、RpcError message、wire 透出的 `error.message (code)` 原样呈现。
+- **设计字面量不进字典**：tool 行 variant 标题（Think/Bash/…）、SYSTEM/USER 类 kind 徽标、Plan chip 字标、StatsLine 全部指标——中英界面显示一致。
+- **ui-trajectory 整包缓做**（开发者检查面，术语密集，单独裁决）。
+- **boot 文案保持硬编码**（AppRoot 渲染早于 locale 服务可用）。
+
+**派生层保持纯函数，本地化只在渲染层**：ui-workspace 的 `relativeTime` 返回结构化 `{unit, n}` 由渲染组合字典模板；blank 会话/未分组桶的存储标题不变，渲染按 `blank` 标志/`workspaceId` 缺席替换本地化文案；**搜索态 blank 行一律排除**（双语标题无法与单语查询稳定匹配）。日期不引 Intl：格式模板进字典（消息时钟 `clock.md`/`clock.ymd`，workspace hover `date.ymd`），格式化函数吃 `t` 参数保持纯。
+
+**测试与 e2e 口径**：`makeTranslate(...dicts)`（dsh-client-test-runtime）镜像服务查找链（首个命中字典胜出、key 兜底、`{name}` 插值），组件测试的 `t` 桩统一用它并以真实 props 席位定型。web e2e 统一 `newEnglishPage`（boot 前钉 `dsh.locale=en`），built-boot snapshot 同样钉 en——golden 对语言迁移免疫；settings 语言切换用例刻意绕开该 helper 覆盖 zh 默认态。
+
+[settings/locale/theme 分层 Note](../../proposed/architecture/2026-07-25-client-settings-locale-theme.md) 中"apply 层订阅 `locale/change` 重注册刷新 label"的机制已被本决定取代（thunk + revision 生命周期）。
+
+## Alternatives considered
+
+- **label 保持 string、语言切换时重注册**（先行包的旧形态）：boot 每包一次注册已很重，`locale/change` 监听者重注册会放大成风暴；ledger version 抖动还会击穿一切按 version 缓存的投影。thunk 把刷新成本移到读取点，读取点本来就跟随 revision。
+- **给 ui-primitives 造 locale context/注入通道**：破坏 zero-cordis 边界（原子组件从此依赖运行时），且强迫未本地化消费者（ui-trajectory）陪跑。props 化让每个消费者独立决定。
+- **错误串进字典**：错误面是排障面，英文原样最利于搜索与上报比对；且 wire 透出串本就不可译，半译反而制造混合语言。
+- **日期用 `toLocaleString()`/Intl**：跟随浏览器/OS 语言而非应用语言，切换后必然产生混合文本；字典模板量小且与消息时钟同构。
+- **blank 行参与搜索（匹配本地化标题或存储标题）**：任一选择都在某个语言下"看得见搜不到"；占位行本无信息量，整体排除语义最稳。
+
+## Consequences
+
+- 语言切换全 UI 即时刷新且零重注册；新包接入 = 字典 + declare-merge + `locale: NS` 三步，无手写胶水。
+- 代价：list label 的消费方必须知道 `resolveSlotLabel`（裸读 `options.label` 拿到函数）；类型上 `SlotLabel` 已挡住多数误用。
+- ui-primitives 的中文默认值在英文语言下依旧是中文，**直到消费点传 label**——未迁移包（ui-trajectory 的 JsonTree）显示英文默认恰好符合其整包英文现状。
+- e2e 英文钉死意味着 zh 默认态主要靠包级组件测试与 settings 语言切换用例覆盖，浏览器 e2e 不再验证 zh 文案。

 Per-session UI state for selection and the active view lives in the declared chat store (`stores.ts` `createChatStore`); the InputHub owns the composer state machine and mirrors its draft into that store for persistence. Apply passes one store handle to the strict session subtree, chat view, and details registrations, so each session shares one instance and the framework owns its lifecycle. Components are pure: the framework standard kit supplies `useSession`/`sessionId`, global `useSessions`/`useWorkspaces`, and the input machine's `useInput`/`inputActions`; store faces and inject factories supply the remaining state and callbacks.
 
-The composer bar declares session-scoped single seats for `'conversation.input.plan'` (right of the local access-mode control) and `'conversation.input.model'` (immediately before the pending indicator and send/stop button), plus list slots for overlay, dock, left, and right input extensions. Feature packages own each control and its state; ui-conversation supplies placement, the `locked` owner prop, and the standard slot shares. While the `plan` projection's effective target is plan mode, InputBar swaps its textarea placeholder to the plan-task wording, localized through the `command.hint` locale namespace this package registers and shared verbatim with the claimed `/plan` command hint (a host-folded value read through the standard-kit `useProjection`; owner-supplied placeholders win). A pending composer takeover remains mounted when another conversation view is active so the blocked agent can still receive its answer; without a pending interaction, the active-session composer belongs to Chat. The composer-bar slot itself is `session-maybe`: with no current session the same bar renders inert (machine faces absent, `disabled` owner prop) instead of swapping in a parallel disabled tree, so the textarea DOM survives the workspace pick; the strict-session control seats simply stay empty until a session exists.

 `src/client/` is organized for the future package split: `contract/` is the sole inter-domain shared face (`slots.ts` slot declarations + composed slot props including the tool-row contract, `views.ts` shared primitives, `tool-call-model.ts`); the `skeleton/`, `chat/`, and `toolviews/` (sample registrants) domain directories import contract files and never each other; `apply.ts` is the only assembly point allowed to import all three domains. The `/client` export surface is the contract only — `apply`/`inject`, the two service classes, and the `contract/` type families; implementation components (skeleton, chat rows) and the store factory stay internal and reach the page exclusively through apply's slot registrations (tests take them via the `./src/*` subpath).

 Plan-mode status chip, a pure browser surface plugin. The browser half occupies the conversation-declared `conversation.input.plan` single seat (to the right of the access-mode control); the node half is an empty apply (the roster row). Plan behavior itself — the `/plan` command, the boundary-or-idle-committed `plan/mode` state, the `plan` projection unit, and the policy section — is owned by [`@deepseek-ai/dsh-plan-mode`](../../plan/plan-mode/README.md), composed independently on the host roster.
 
-Plan mode is entered through the `/plan` command only; there is no UI control that turns it on. While the host-computed `plan` projection's effective target is plan mode (`pending ? !active : active` — a folded host value, not client optimism, so an arriving frame corrects the chip either way), the seat renders a read-only "Plan" chip whose hover × executes `/plan off` through `command.execute`; otherwise the seat stays empty — a host without plan-mode (or a Draft with no session) shows nothing. While plan mode is the effective target, the composer textarea's placeholder switches to the plan-task hint — "describe your task to generate plan", localized through ui-conversation's `command.hint` locale namespace and shared verbatim with the claimed `/plan` command hint (rendered by the composer from the same projection; owner-supplied placeholders win).

 The chip carries the accessible description "Plan mode on, press to turn off". Admission failures (`matched: false`, business errors, transport faults) surface as an inline error and the chip stays until the projection confirms the exit.

 Plan mode 状态徽章，纯浏览器 surface 插件。浏览器侧占据会话声明的 `conversation.input.plan` 单座（位于 access 模式控件右侧）；node 侧是空 apply（roster 行）。plan 行为本身——`/plan` 命令、边界或空闲即时提交的 `plan/mode` 状态、`plan` 投影单元与 policy 段——归 [`@deepseek-ai/dsh-plan-mode`](../../plan/plan-mode/README.md) 所有，由 host roster 独立组合。
 
-plan mode 只经 `/plan` 命令进入；UI 上没有打开它的控件。当 host 计算的 `plan` 投影有效目标为 plan mode 时（`pending ? !active : active`——折叠的 host 值而非客户端乐观态，帧到达即自动纠正），座位渲染一个只读 "Plan" chip，hover 出现的 × 经 `command.execute` 执行 `/plan off`；否则座位保持为空——未组合 plan-mode 的 host（或尚无会话的 Draft）不显示任何内容。plan mode 为有效目标期间，composer 文本框的 placeholder 切换为 plan 任务提示——"describe your task to generate plan"（中文「描述你的任务以生成计划」），经 ui-conversation 的 `command.hint` locale 命名空间本地化，并与已认领 `/plan` 命令的提示逐字共用同一份文案（由 composer 从同一投影渲染；owner 提供的 placeholder 优先）。

 chip 携带无障碍描述 "Plan mode on, press to turn off"。准入失败（`matched: false`、业务错误、传输故障）以内联错误呈现，chip 保持显示直至投影确认退出。

 - **Glyph-level icons are redrawn approximations** — the fish logo (and the sparkle held by ui-conversation) come from font glyphs whose vector geometry is not exportable from the local design data; hand-authored recreations stand in until an exact export path exists.
 - **Pill and Input have no design source** — both atoms are self-defined; the sidebar search field and view-tab strip that resemble them are consumer-owned compositions, not these atoms.
 - **StateDot `Active` variant is a hidden placeholder in the design** — not implemented; the four shipped states (done/warning/ongoing/error) are the complete P-I surface.
-- **This package's user-facing copy is inline Chinese, not localized** — the atoms are zero-cordis and so cannot reach `ctx.locale`; `TerminalBlock`'s exit-code and signal pills, its copy and expand controls, and `CodeBlock`'s copy control are all hardcoded. This matches the repo-wide state the locale package records (only the Settings surface is translated); extracting these into the `zh`/`en` dictionaries needs a localization channel for zero-cordis atoms and belongs to that repo-wide extraction.
+- **User-facing copy localizes through label props, defaulting to the original Chinese literals** — the atoms are zero-cordis and cannot reach `ctx.locale`, so `TerminalBlock` (`labels`), `JsonTree` (`labels`), `CodeBlock` (`copyLabel`/`copiedLabel`), `MarkdownText` (`codeLabels`), `JsonBlock` (`truncatedLabel`), `ConnectionBanner` (`label`), and `Modal` (`closeLabel`) take their copy as optional props with the previous hardcoded strings as defaults. Localized plugins pass dictionary-driven labels from their own `t` seat; a consumer that passes nothing renders exactly the pre-localization output.
 - **`TerminalBlock` is not a terminal emulator** — it renders settled or still-running command output, not an interactive session: SGR color and attributes are honored, and so are the in-line cursor movements a progress line uses — carriage return, backspace, erase-in-line, tab stops and character width. Absolute cursor positioning, screen clearing, and alternate-screen sequences are stripped. Basic-16 magenta and cyan have no token equivalent and stay literal rgb.

 - **字形级图标是重新绘制的近似版本**：鱼形标志（以及 ui-conversation 持有的闪光图标）来自字体字形，而本地设计数据无法导出其矢量几何；在获得精确导出路径前，使用手工重建版本代替。
 - **Pill 与 Input 没有设计来源**：两个原子组件均自行定义；与其相似的侧边栏搜索字段和视图标签条由消费方组合，不是这些原子组件。
 - **StateDot 的 `Active` 变体是设计中的隐藏占位符**：尚未实现；已交付的四种状态（done/warning/ongoing/error）构成完整的 P-I 表层。
-- **本包面向用户的文案是内联中文，未做本地化**：这些原子组件是 zero-cordis 的，因此拿不到 `ctx.locale`；`TerminalBlock` 的退出码与信号胶囊、它的复制与展开控件，以及 `CodeBlock` 的复制控件全部硬编码。这与 locale 包记录的全仓现状一致（只有 Settings 表面做了翻译）；把它们抽取进 `zh`/`en` 字典需要为 zero-cordis 原子组件提供一条本地化通道，属于那次全仓抽取的范围。
+- **面向用户的文案经 label props 本地化，默认值为原中文字面量**：这些原子组件是 zero-cordis 的，拿不到 `ctx.locale`，因此 `TerminalBlock`（`labels`）、`JsonTree`（`labels`）、`CodeBlock`（`copyLabel`/`copiedLabel`）、`MarkdownText`（`codeLabels`）、`JsonBlock`（`truncatedLabel`）、`ConnectionBanner`（`label`）和 `Modal`（`closeLabel`）都把文案作为可选 props 接收，默认值即此前的硬编码字符串。已本地化的插件用自己的 `t` 席位传入字典驱动的 label；什么都不传的消费者渲染与本地化之前逐字节一致。
 - **`TerminalBlock` 不是终端模拟器**：它渲染已结束或仍在运行的命令输出，而不是交互式会话：SGR 颜色与属性会被遵循，进度行所用的行内光标移动同样被遵循——回车、退格、行内擦除、制表位与字符宽度。绝对光标定位、清屏与备用屏幕序列会被剥离。基础 16 色中的洋红与青色没有对应 token，保持字面 rgb。

The shell ships no copy of its own — all text arrives from registrants (ui-settings-general owns chrome and General; features own their sections, rows, and onboarding overlays). Nav labels may be locale-following thunks, so the nav projection resolves them through `resolveSlotLabel` and re-renders on the section ledger bump or the locale revision (an optional `ctx.get('locale')` read; no hard locale dependency).
 
 The shell supplies onboarding registrants only two navigation facts: whether the session surface is the empty Hero and an `openSection(id)` callback that opens the panel on a registered section. Registrants own capability readiness, dismissal, copy, and mutations; the shell therefore does not become a second configuration fact source.

 外壳只向首次使用注册方提供两个导航事实：当前会话界面是否为空白 Hero，以及一个 `openSection(id)` 回调；后者会打开设置面板并切换到已注册的指定分区。能力就绪状态、浮层关闭、文案和变更操作均由注册方持有，因此外壳不会成为第二个配置事实来源。

Subject: [PATCH 099/102] ci: run coverage-exempt heavy suites uninstrumented
 in parallel

The coverage lane's wall clock was pinned by a few compiler- and
subprocess-bound suites whose v8 instrumentation tax is a multiple of
their runtime while contributing nothing the per-file thresholds need:
typert generator fixtures (whole-workspace compiler analysis; its src is
threshold-excluded) and three scripts/ child-process fixture suites
(scripts/ sources are never coverage-measured; in-process imports are
covered by their owning package tests).

Split ci-coverage into two parallel gates: the instrumented run sets
DSH_COVERAGE_EXEMPT_HEAVY=1 and vitest.config.ts drops the exempt suites
from both projects (CLI --exclude cannot reach per-project include
resolution); a second uninstrumented gate runs exactly those suites, so
the aggregate still executes every test. Membership contract and the
filter/exclude pairs live in scripts/coverage-exempt.ts.

Local 6-worker A/B: instrumented gate 900s -> 260s wall; exempt gate
262s wall runs beside it, so the lane converges near the slower of the
two (~4.4min vs ~7min single-gate). DSH_GATE_CONCURRENCY now has two
schedulable gates in this lane.

+
+Status: implemented

+
+## Problem
+
+The CI coverage lane (`check:ci:coverage`) had its wall clock pinned by a handful of heavy test files: in a local 6-worker full-suite profile, 555 test files aggregated 1595 seconds, with `packages/typert/generator/tests/type-model.spec.ts` alone at 885 seconds and the top 10 files holding 84% of the aggregate. These suites share one shape — every case performs whole-workspace compiler analysis or drives real subprocess fixtures — and v8 instrumentation multiplies exactly that kind of runtime.
+
+The decisive waste: the instrumentation tax these suites paid contributed **nothing** to the per-file 100% thresholds — the measured code they execute in-process is either outside the threshold scope already or independently fully covered by other suites. Running them instrumented traded lane time for zero information.
+
+## Decision
+
+The `ci-coverage` aggregate splits into two parallel gates; every test still runs, and only the heavy suites stop paying the instrumentation tax:
+
+- **Instrumented gate** (`test:coverage`): sets `DSH_COVERAGE_EXEMPT_HEAVY=1`, which makes `vitest.config.ts` drop the exempt suites from both projects' excludes; every remaining file runs instrumented and carries the entire threshold proof. The variable is injected through the gate's own env (the existing `Gate.env` mechanism), not the workflow-global environment, so the uninstrumented gate beside it and any local `vitest run` never see it and behave unchanged.
+- **Uninstrumented gate** (`test:coverage-exempt-heavy`): runs exactly the exempt suites through paired positional filters, keeping the correctness signal whole.
+
+`scripts/coverage-exempt.ts` is the single roster point, holding the membership contract and the filter/exclude pairs so the two sides cannot drift.
+
+### The roster, reconciled entry by entry
+
+A suite contributes to coverage exactly when it executes measured files in-process (`coverage.include` spans the package src trees). The current roster, audited:
+
+| Exempt suite | Measured code executed in-process | Who carries the coverage |
+| --- | --- | --- |
+| All 6 typert generator specs | The generator's own src | Generator src is threshold-excluded as a package (`vitest.config.ts`) — outside the threshold scope to begin with |
+| tools-catalog.spec additionally imports | `typert-registry` and `tool-cordis` src | Each package's own tests cover them fully (verified with focused coverage runs, zero threshold errors) |
+| `scripts/install-lefthook.spec.ts`, `scripts/oxlint-contract.spec.ts`, `scripts/change-scope.spec.ts` | None — they test `scripts/` sources (never in `coverage.include`) and work by spawning child processes | Nothing to carry |
+
+### Membership contract
+
+A new exemption must satisfy both: every measured file the suite executes in-process is already fully covered by other suites (or threshold-excluded), and the filter and exclude select exactly the same file set. The contract text lives beside the roster in the same file.
+
+### The gate polices the roster automatically
+
+The per-file 100% thresholds are themselves the roster's guard; a wrong roster cannot pass silently:
+
+- If a future exempt suite in fact solely covers some measured file, the instrumented gate goes red on the spot (that file drops below 100%).
+- The converse holds too: new code covered only by an exempt suite turns the gate red immediately.
+
+Coverage-result invariance therefore does not rest on humans maintaining the roster, in line with the misconfiguration-fails-loud convention. The only thing given up is that the exempt suites' own execution no longer produces coverage data — the table above shows that data was entirely redundant, so the final report is file-for-file identical in threshold terms.
+
+## Alternatives considered
+
+- **CLI `--exclude` to drop the exempt suites from the instrumented gate.** Proven ineffective: vitest 4's `cliExclude` does not participate in per-project include resolution, so under a multi-project config the exempt suites stayed selected; the env + config route replaced it.
+- **Lowering worker counts or raising gate concurrency.** Measured ineffective during the incident: the lane's wall clock was pinned by the longest tail files (aggregate/wall ≈ 4× effective parallelism), and the concurrency knobs moved nothing in either direction.
+- **Cross-runner sharding (`--shard` + blob merge).** Would compress the wall clock further but adds matrix, artifact-pipeline, and merge-job complexity; with the split landed the lane sits near 2 minutes, which does not justify the cost. Revisit if the suite grows substantially.
+- **Deleting or skipping the heavy suites.** Rejected: they are the sole correctness evidence for the typert generator and the scripts tooling; running them uninstrumented in parallel preserves the full signal.
+
+## Verification
+
+Measured on CI (16-core runner): the gate segment went from 424 seconds to the two gates in parallel — `test:coverage` 95.9 s + `test:coverage-exempt-heavy` 71.1 s — with the lane converging on the slower at about 96 seconds; the instrumented gate reported zero threshold errors both before and after the split. `vitest list` verifies the env toggle adds and removes exactly the exempt set; `run-gates.spec.ts` covers the aggregate graph construction.
+
+## Consequences
+
+- The coverage lane's gate segment drops from about 7 minutes to about 96 seconds with no change in threshold outcome or executed test set.
+- `DSH_GATE_CONCURRENCY` has two schedulable gates in this lane again, so the aggregate scheduler is no longer a pass-through.
+- Adding a heavy suite to the roster requires the membership audit above; a wrong entry fails the instrumented gate loudly rather than eroding coverage silently.
+- The exempt suites no longer appear in the coverage report's file list of contributors; their correctness signal lives solely in the uninstrumented gate's pass/fail.

+# Agent Note: 覆盖率豁免重型套件
+
+Status: implemented
+
+[English](2026-07-31-coverage-exempt-heavy-suites.md) | 中文
+
+## Problem
+
+CI 覆盖率 lane（`check:ci:coverage`）的墙钟被少数几个重型测试文件钉死：本地 6-worker 全量剖析中，555 个测试文件聚合 1595 秒，其中 `packages/typert/generator/tests/type-model.spec.ts` 一个文件占 885 秒，前 10 个文件占聚合时长的 84%。这类套件的共同点是每个用例都做全工作区编译器分析或真实子进程 fixture，v8 插桩把这类代码的运行时间放大数倍。
+
+关键的浪费在于：这些套件缴纳的插桩税对 per-file 100% 阈值**没有任何贡献**——它们进程内执行的被度量代码，要么本来就不在阈值口径内，要么已由其他套件独立满覆盖。继续在插桩下运行它们，纯粹是用 lane 时长换零信息。
+
+## Decision
+
+`ci-coverage` 聚合拆成两个并行 gate，全部测试仍然执行，只有重型套件不再交插桩税：
+
+- **插桩 gate**（`test:coverage`）：设 `DSH_COVERAGE_EXEMPT_HEAVY=1`，`vitest.config.ts` 据此从两个 project 的 exclude 中剔除豁免套件，其余全部文件照旧插桩并承担全部阈值证明。经 gate 自带 env 注入（既有 `Gate.env` 机制），不进 workflow 全局环境，因此并排的无插桩 gate 和本地直跑 `vitest run` 都看不到该变量、行为不变。
+- **无插桩 gate**（`test:coverage-exempt-heavy`）：用配对的 positional filter 恰好运行豁免套件，保证正确性信号不缩水。
+
+`scripts/coverage-exempt.ts` 是唯一名单点，集中持有成员资格契约与 filter/exclude 配对，防止两侧漂移。
+
+### 豁免名单与逐项对账
+
+一个套件对覆盖率有贡献，当且仅当它在进程内执行了被度量的文件（`coverage.include` = 包 src 树）。现行名单逐项核对：
+
+| 豁免套件 | 进程内执行的被度量代码 | 覆盖由谁接住 |
+| --- | --- | --- |
+| typert generator 全部 6 个 spec | generator 自身 src | generator src 已整包 threshold-excluded（`vitest.config.ts`），本不在阈值口径内 |
+| 其中 tools-catalog.spec 额外 import | `typert-registry`、`tool-cordis` 的 src | 两包各自的测试独立满覆盖（focused coverage 实测无阈值错误） |
+| `scripts/install-lefthook.spec.ts`、`scripts/oxlint-contract.spec.ts`、`scripts/change-scope.spec.ts` | 无——被测对象是 `scripts/` 源码（从不在 coverage.include），执行方式是 spawn 子进程 | 无需接 |
+
+### 成员资格契约
+
+新增豁免必须同时满足：套件进程内执行的每个被度量文件都已由其他套件满覆盖（或在阈值排除名单内）；filter 与 exclude 选中完全相同的文件集。契约文本随名单同文件维护。
+
+### 门禁自动守卫名单正确性
+
+per-file 100% 阈值本身就是豁免名单的守卫，名单错误无法静默通过：
+
+- 若未来某个豁免套件实际独家覆盖着某个被度量文件，插桩 gate 当场红（该文件跌破 100%）；
+- 反向同理：出现"只有豁免套件才覆盖"的新代码，同样立刻红。
+
+因此覆盖率结果的不变性不依赖人工维护名单，符合"misconfiguration fails loud"约定。唯一失去的是豁免套件自身的执行不再产出覆盖数据——由上表可知这些数据全部冗余，最终报告在阈值意义上逐文件相同。
+
+## Alternatives considered
+
+- **CLI `--exclude` 从插桩 gate 剔除豁免套件。** 实证无效：vitest 4 的 `cliExclude` 不参与 per-project include 解析，多 project 配置下豁免套件仍被选中，故改走 env + config。
+- **降低 worker 数或提高 gate 并发。** 事故期间实测无效：lane 墙钟被尾部最长文件钉死（聚合/墙钟 ≈ 4× 有效并行），并发旋钮两个方向都动不了尾巴。
+- **跨 runner 分片（`--shard` + blob 合并）。** 能进一步压墙钟但引入 matrix、artifact 管道与合并 job 的复杂度；拆分落地后 lane 已到约 2 分钟，不值得付。若未来套件规模再涨可重新评估。
+- **直接删除或跳过重型套件。** 拒绝：它们是 typert generator 与 scripts 工具的唯一正确性证据，无插桩并排执行保住全部信号。
+
+## Verification
+
+CI 实测（16 核 runner）：拆分前 gate 段 424 秒，拆分后两 gate 并行 `test:coverage` 95.9 秒 + `test:coverage-exempt-heavy` 71.1 秒，lane 收敛于较慢者约 96 秒；拆分前后插桩 gate 阈值错误均为零。`vitest list` 验证 env 开关两态恰好增删豁免集；`run-gates.spec.ts` 覆盖聚合图构造。
+
+## Consequences
+
+- 覆盖率 lane 的 gate 段从约 7 分钟降到约 96 秒，阈值结果与执行测试集均无变化。
+- `DSH_GATE_CONCURRENCY` 在本 lane 重新拥有两个可调度对象，聚合调度器不再是直通。
+- 向名单新增重型套件必须完成上述成员资格对账；错误条目会让插桩 gate 大声失败，而不是静默侵蚀覆盖率。
+- 豁免套件不再出现在覆盖率报告的贡献文件列表中；其正确性信号完全由无插桩 gate 的红绿承载。

Subject: [PATCH 101/102] fix(ci): review follow-ups for the coverage lane
 split

- Split DSH_COVERAGE_MAX_WORKERS between the two parallel gates
  (instrumented gets ~2/3, exempt gets ~1/3, both at least 1) so the
  lane never exceeds the budget the failover pool's 8 x 6-instance
  bound assumes; a budget of 1 pairs with DSH_GATE_CONCURRENCY=1 on
  the serial reference lanes, which already prevents gate overlap.
- Fail loud on a set-but-not-'1' DSH_COVERAGE_EXEMPT_HEAVY value in
  vitest.config.ts instead of silently ignoring it.
- Add coverage-exempt.spec.ts: each roster entry's filter and exclude
  must select the same non-empty spec set and entries must not
  overlap, so a renamed suite breaks the gate instead of silently
  returning to the instrumented run with a stale roster.

 Renaming the seam's plugin id is now a compile error in the client: `TS2322: Type '"compact"' is not assignable to type '"compaction"'`. The import must stay **type-only** — a value import of any `@deepseek-ai` package that is neither a platform module nor an inline-safe wire layer is rejected by the client purity gate (`packages/client/tsdown.client.ts`), whose own message records that type-only imports are erased and never reach it. A type-only leaf import needs both a `tsconfig.base.json` `paths` entry and `{"path": "../../compact/compact"}` in `packages/client/runtime/tsconfig.json` `references`: composite `rootDir` rules apply to erased imports as well, and without the reference the diagnostic is `TS6059`/`TS6307`.
 
-`packages/client/runtime/tests/compact-checkpoint-pin.spec.ts` stays as the behavioral half, driving the adapter with a checkpoint built from the canonical **value**. It runs in the client **test** program, which may value-import the root; a `packages/client/*` package program may not.

The test value-imports the cordis-free `@deepseek-ai/dsh-compact/checkpoint` leaf and deliberately never loads the compact package root or the host-side `Context` merges reachable through it.
 
 The divergence from the terminal is therefore narrow: both frontends recognize a checkpoint from the same declaration — the terminal value-imports `isCompactCheckpointSource` host-side, where no gate applies, and the client pins the type.
