+# 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.

+## 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 optional `dsh-session/invariant` companion enforces the relations owned by core: turn and step numbering, execution-event enclosure, and same-step tool call/result pairing. Merge-extensible event relations belong to the plugin that declares them, so core does not reject an unknown event merely because no turn is open. See [the standalone-event decision](../../.agents/notes/implemented/simplification/2026-07-28-remove-synthetic-log-only-turns.md).

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

 A plugin may declaration-merge extra `SessionEventMap` types. These are **log-only**: NOT `SurfaceEventType`s (they carry no `surfaceOp` and contribute nothing to derived history). Their owner decides whether they belong to an open execution turn or may stand between turns, and enforces any relation in its own invariant companion. The full per-event enumeration — core and plugin-contributed alike, with payloads and provenance — is the generated [persistence log event catalog](../persistence-catalog.md); the compaction seam's `compact/*` semantics are discussed on [compaction.md](compaction.md).

+# User Settings
+
+English | [中文](settings.zh.md)
+
+The user-settings seam of [dsh-settings](../../packages/settings/settings) holds one user-owned document of per-namespace sections and resolves each registered namespace as schema defaults, then the registrant's composition `base`, then the user section. Providers such as [dsh-settings-local](../../packages/settings/settings-local) store the raw document and push external edits; consumer plugins register a schema and read or observe the resolved value. Composition config stays in `cordis.yml` — a namespace carries only the user-editable subset.
+
+Source: [`packages/settings/settings/src/index.ts`](../../packages/settings/settings/src/index.ts)
+
+## Identity
+
+A namespace names one plugin-owned section of the user document. The brand keeps namespaces from mixing with other cross-boundary ids; construction validates the lowercase kebab-case shape.
+
+```ts type-equiv
+/** Nominal id of one registered settings namespace. */
+type SettingsNamespace = Branded<'SettingsNamespace'>
+```
+
+## Registration
+
+Registration binds a schemastery schema to a namespace on the calling plugin's fiber — disposing that fiber removes the namespace and its observers. The options carry the composition layer and the owner's effect timing.
+
+```ts type-equiv
+/** Registration options beyond the namespace schema. */
+interface SettingsRegisterOptions<T> {
+  /** Composition-layer values resolved below the user layer (entry-config subset). */
+  base?: Partial<T>
+  /** Owner's effect timing, surfaced to configuration UIs; defaults to `live`. */
+  applies?: SettingsApplies
+}
+```
+
+`applies` is a UI hint, not a mechanism: a `restart` owner simply never watches, so its value is read once at construction and configuration surfaces can badge the pending change.
+
+```ts type-equiv
+/** When a namespace's changes take effect for its owner. */
+type SettingsApplies = 'live' | 'restart'
+```
+
+## Owner scope
+
+The scope is the owner-facing handle. `update` merges a sparse patch over the user section only (never into `base`); `replace` sets the section wholesale, which is the removal/reset path — keys absent from the replacement re-inherit `base` and schema defaults. Writes to one namespace are serialized in call order, and resolved values are deep-frozen snapshots.
+
+```ts type-equiv
+/** Owner-facing handle for one registered namespace. */
+interface SettingsScope<T> {
+  /** Current resolved value: schema defaults, then `base`, then the user layer. */
+  get(): T
+  /**
+   * Observe committed changes to this namespace's resolved value. Invocations
+   * of one callback run asynchronously, one at a time, in commit order; a
+   * rejection is contained and logged like a sync throw. After the disposer
+   * returns, no further invocation starts — one already queued is skipped;
+   * one already started still settles, and service disposal waits for it.
+   * @param callback - invoked after each commit with the next and previous values.
+   * @returns the disposer removing this observer.
+   */
+  watch(callback: (next: T, prev: T) => void | Promise<void>): () => void
+  /**
+   * Merge a partial patch into this namespace's user layer and persist it.
+   * @param patch - plain-object patch over the user section; JSON-shaped data
+   * only (non-JSON values reject with their path before anything persists).
+   */
+  update(patch: object): Promise<void>
+  /**
+   * Replace this namespace's user section wholesale; absent keys re-inherit
+   * the composition `base` and schema defaults (`replace({})` resets all).
+   * @param section - the complete next user section; JSON-shaped data only,
+   * as for {@link update}.
+   */
+  replace(section: object): Promise<void>
+}
+```
+
+## Descriptors
+
+`describe()` serializes every registered namespace for configuration surfaces: the schemastery `toJSON()` envelope drives schema-rendered forms, and the resolved value fills them.
+
+```ts type-equiv
+/** One registered namespace as surfaced to configuration UIs. */
+interface SettingsDescriptor {
+  /** The registered namespace. */
+  ns: SettingsNamespace
+  /** Serialized schemastery schema (`schema.toJSON()`). */
+  schema: unknown
+  /** Current resolved value. */
+  value: unknown
+  /** Owner's declared effect timing. */
+  applies: SettingsApplies
+}
+```
+
+## Change commits
+
+Every committed change — an in-process write or an externally observed provider edit — emits `settings/updated (ns, next, prev, source)` after the new value is authoritative, and never when the resolved value is deep-equal. The source tag separates the two entry paths.
+
+```ts type-equiv
+/** Origin of one committed settings change. */

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.

 - **Coverage gate** (`pnpm run test:coverage`): the gating run, per-file 100% on `packages/*/*/src`. An uncovered line is often dead code the gate is correctly flagging for deletion, not a missing test to bolt on. Line coverage is necessary, never sufficient — it proves lines ran, not that the feature works as shipped.
 - **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
 - **Snapshot** (`pnpm run test:snapshot`): keyless expected outputs cover external behavior — transport contracts and presentation, while persisted logs pin assembled backend behavior. ACP boots the real automation-server example, replays a recorded session, and diffs normalized JSON-RPC plus the re-persisted log ([ACP snapshot Agent Note](../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md)); headless pins `stream-json` through its real one-shot process. TUI journeys replay primary/child JSONL through the real loop and tools, then project ANSI into semantic terminal-state outputs; package snapshots retain transient states and a real PTY covers the process boundary ([TUI snapshot Agent Note](../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md)). Use `pnpm run test:snapshot:record` when a model transcript changes and `pnpm run test:snapshot:refresh` when replay input remains valid; review every JSONL and expected-output diff. One ACP scenario (`text-turn`) pins full system-prompt/tool-schema content; other fixtures tokenize it so an edit churns one line ([pinned-header Agent Note](../.agents/notes/archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).
- **Web browser snapshot** (gate-exempt `pnpm run test:web`): real chromium over the in-process web composition replays recorded fixtures against conversation aria goldens (`apps/web/tests/snapshots/`); record/refresh semantics and the deferred CI browser decision: [web e2e lane Agent Note](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md).

+- **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares replayed browser output with `apps/web/tests/snapshots/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` [builds first](../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md) for plugin CSS.

 Committed session-format JSONL uses the canonical packed-row layout, and the keyless snapshot gate discovers every such fixture by its `session` header. In-flight branches carrying older fixture edits merge current `master` and run the [temporary migrator](../scripts/migrate-packed-session-fixtures.ts) through `pnpm run migrate:packed-session-fixtures`; the [removal proposal](../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) retires that command and these links after all affected branches converge.

+Notes for using the `str_replace` command:
+* The `old_str` parameter should match EXACTLY one or more consecutive lines from the original file. Be mindful of whitespaces!
+* If the `old_str` parameter is not unique in the file, the replacement will not be performed. Make sure to include enough context in `old_str` to make it unique
+* The `new_str` parameter should contain the edited lines that should replace the `old_str`

 Plugins load in file order. Place plugins that depend on services after the applications or capability plugins that provide them. Missing models, tools, and plugins fail as early as possible instead of being silently ignored.

+## CLI overlays
+
+The TUI composes `base.cordis.yml` and `tui.cordis.yml`, then applies one optional patch list. By default that final list is `~/.dsh/config.yaml`; `dsh --config <path>` replaces the personal list with the named overlay. `dsh --config-replace <path>` instead boots the named file as the complete tree, without shipped or personal layers. `dsh web --config <path>` adds its overlay after the shared base and Web surface defaults and before Web profile and CLI-flag patches.
+
+A patch replaces a row's entire `config` value; it does not deep-merge keys. For example, patching `llm-deepseek` with only `config: { thinking: disabled }` also removes that row's configured `apiKey` and `baseURL`, so restate every key the row must retain.
+
 ## JavaScript values and environment variables

 The Cordis loader evaluates runtime expressions tagged with `!!js`. Keep API keys and other secrets in the gitignored `.env` file at the repository root, never in committed configuration.

 插件按文件中的顺序加载。依赖其他服务的插件应该排在提供这些服务的应用或能力插件之后；引用不存在的模型、工具或插件会尽早报错，而不是被静默忽略。

+## CLI 覆盖层
+
+TUI 先组合 `base.cordis.yml` 与 `tui.cordis.yml`，再应用一个可选补丁列表。默认的最后一层是 `~/.dsh/config.yaml`；`dsh --config <path>` 会以指定覆盖替代个人补丁列表。`dsh --config-replace <path>` 则把指定文件作为完整配置树启动，不使用已交付配置或个人层。`dsh web --config <path>` 会在共享基础配置与 Web 界面默认值之后、Web profile 与命令行标志补丁之前添加覆盖。
+
+补丁会替换目标行的整个 `config` 值，而不是深度合并各个键。例如，只用 `config: { thinking: disabled }` 修补 `llm-deepseek`，也会移除该行原有的 `apiKey` 与 `baseURL`；因此必须重新写出该行需要保留的全部键。
+
 ## JavaScript 值和环境变量

 Cordis loader 使用 `!!js` 标签读取运行时表达式。API key 等凭据应放在仓库根目录、已被 Git 忽略的 `.env` 中，不能提交到配置文件。
