+# Agent Note: dsh --dump-config prints the composed config tree
+
+Status: implemented
+
+English | [中文](2026-07-30-dsh-dump-config.zh.md)
+
+## Problem
+
+The booted tree is a composition the user never sees: the shipped base, a surface overlay, and the `--config` or personal `~/.dsh/config.yaml` overlay apply as sibling patch lists where each id-targeted patch replaces the row's whole `config` and an unmatched id only warns. Debugging a misbehaving personal overlay (a restated field dropped, a row id typo, a patch applying to the wrong surface) required mentally replaying the patch algorithm across three files. There was no way to see the effective tree or to diff it against the shipped defaults.
+
+## Decision
+
+`dsh --dump-config` and `dsh web --dump-config` print the composed entry list — base, surface overlay, then the `--config` or personal overlay, exactly the layers that surface's boot assembles — as YAML on stdout and exit without booting. `dsh --dump-default-config` / `dsh web --dump-default-config` stop at the surface overlay, so diffing the two outputs shows precisely what the user layer changes.
+
+The dump cannot drift from what boots because it shares the mounting code: the vendored include exports its patch algorithm as the pure `applyEntryPatches(data, patches, warn)` (the private `applyPatches` method now delegates to it) and its `!!js` YAML dialect as `entryListSchema`; `dsh-app-boot`'s `renderConfigDump()` composes labeled layers and renders through both, and `apps/cli/src/dump-config.ts` is a thin surface-selection wrapper. `!!js` expressions print verbatim and unevaluated — the dump shows composition, not one process's environment — and a patch whose target row is absent goes to stderr with its layer label, mirroring the Loader's boot-time warning. Launcher-owned boot-context values (session identity, web CLI-flag patches, the frontend dist path) are per-invocation facts outside the config tree and do not appear. The dump flags reject boot-only flags (`-p`, `--resume`, `--config-replace`) and each other, and `--dump-default-config` takes no `--config`.
+
+Each run of same-provenance rows is preceded by a `# ==` comment naming the file that contributed the rows and the layers that patched them (`# == base.cordis.yml, patched by tui.cordis.yml`), so the output shows which section comes from which file while remaining one loadable YAML document. Composition is one flattened `applyEntryPatches` call over all layers — boot's exact call shape, so even patch-visibility corner cases (a later layer targeting a group child that a plain `config` replacement introduced, invisible to the single-pass id index) compose identically; applying one call per layer would rebuild the index between layers and print a tree boot never mounts. Provenance is derived from single-call prefix snapshots (base + layers 1..k) diffed positionally: the patch algorithm only rewrites rows in place or appends, so a top-level index identifies one row across snapshots, and a layer counts as having patched a row when adding it changed that row (config replacement, disable, group insert). Patch lists are cloned per snapshot because `applyEntryPatches` pushes `insert` rows by reference from the patch list.
+
+`dsh-app-boot` previously duplicated the include's `!!js` YAML type for patch parsing; it now imports `entryListSchema`, so the dialect has one owner.
+
+## Alternatives considered
+
+**Boot the tree and dump `ctx.loader.entries()`.** Rejected: booting evaluates `!!js` expressions (leaking one machine's environment into the printed config), starts adapters and sessions as side effects, requires a TTY-independent teardown path, and is slow. The dump is for debugging composition, which is a pure function of the files.
+
+**Reimplement the patch merge in the CLI.** Rejected: a second implementation of `applyPatches` would silently drift from the vendored include — the exact failure mode the feature exists to debug. Exporting the include's own algorithm costs one logged vendor modification and guarantees identity.
+
+**A `/dump-config` TUI command instead of flags.** Rejected as the only form: the primary use is a piped `dsh --dump-config | diff - <(dsh --dump-default-config)` style workflow, which needs a boot-free non-TTY surface. A TUI command can be added later over the same `renderConfigDump`.
+
+## Consequences
+
+Config debugging becomes one command instead of mental patch replay, and support can ask for `--dump-config` output. The vendored include carries one more logged local modification (the `applyEntryPatches`/`entryListSchema` exports; behavior-preserving for mounting) to re-apply on upstream sync. Provenance tracking re-composes one prefix snapshot per layer and diffs rows by JSON stringify, so the dump does extra work proportional to layers² × rows; that cost lives only in the boot-free dump path. `renderConfigDump` is unit-tested for layer ordering, verbatim `!!js` round-tripping, provenance separators and grouping, labeled unmatched-patch warnings, and loud read/parse/shape failures; the built-bin e2e drives all four flag forms through `lib/bin.js` including the personal-overlay layer, its provenance label, and its stderr warning.

+# Agent Note: dsh --dump-config 打印合成后的配置树
+
+Status: implemented
+
+[English](2026-07-30-dsh-dump-config.md) | 中文
+
+## Problem
+
+启动的配置树是一份用户从未见过的合成结果：已交付的基础配置、界面覆盖层，以及 `--config` 或个人 `~/.dsh/config.yaml` 覆盖层作为同级补丁列表依次应用，其中每个按 id 定向的补丁替换目标行的整个 `config`，未匹配的 id 只产生警告。调试一个行为异常的个人覆盖层（漏掉需要重述的字段、行 id 拼错、补丁应用到了错误的界面）需要在脑中跨三个文件重放补丁算法。既没有办法看到生效的树，也没有办法把它与已交付的默认值做 diff。
+
+## Decision
+
+`dsh --dump-config` 和 `dsh web --dump-config` 把合成后的条目列表——基础配置、界面覆盖层、再叠 `--config` 或个人覆盖层，恰好是该界面启动时组装的那些层——以 YAML 打印到 stdout 后退出，不启动任何东西。`dsh --dump-default-config` / `dsh web --dump-default-config` 止步于界面覆盖层，因此对两份输出做 diff 就能精确看出用户层改了什么。
+
+dump 不可能与实际启动漂移，因为它复用挂载代码：vendored include 把补丁算法导出为纯函数 `applyEntryPatches(data, patches, warn)`（私有的 `applyPatches` 方法现在委托给它），并把 `!!js` YAML 方言导出为 `entryListSchema`；`dsh-app-boot` 的 `renderConfigDump()` 通过这两者对带标签的层完成合成与渲染，`apps/cli/src/dump-config.ts` 只是选择界面的薄封装。`!!js` 表达式原样打印、不求值——dump 展示的是合成结果，不是某个进程的环境——目标行不存在的补丁会连同其层标签报到 stderr，与 Loader 启动时的警告一致。由启动器持有的启动上下文值（会话身份、web 的 CLI 标志补丁、前端 dist 路径）是每次调用的事实，位于配置树之外，不会出现。dump 标志拒绝仅用于启动的标志（`-p`、`--resume`、`--config-replace`）且两个 dump 标志互斥，`--dump-default-config` 不接受 `--config`。
+
+每段来源相同的连续行之前都有一条 `# ==` 注释，标明贡献这些行的文件以及修补过它们的层（`# == base.cordis.yml, patched by tui.cordis.yml`），因此输出既展示每一节来自哪个文件，又仍是一份可加载的 YAML 文档。合成是对所有层展平后的一次 `applyEntryPatches` 调用——与启动的调用形状完全一致，因此即便是补丁可见性的边角情况（后一层定位到前一层通过普通 `config` 替换引入的组内子项，而单遍 id 索引看不到它）也与启动合成完全相同；若按层各调用一次，会在层与层之间重建索引，打印出一棵启动从不挂载的树。来源从单次调用的前缀快照（基础 + 第 1..k 层）按位置 diff 得出：补丁算法只会原地改写行或在末尾追加，因此顶层索引在各快照之间标识同一行；加入某层后该行发生变化（替换 config、禁用、组内插入）即视为该层修补了这一行。每个快照都会克隆补丁列表，因为 `applyEntryPatches` 会把 `insert` 行按引用从补丁列表推入结果。
+
+`dsh-app-boot` 之前为解析补丁复制了 include 的 `!!js` YAML 类型；现在改为导入 `entryListSchema`，方言只有一个归属者。
+
+## Alternatives considered
+
+**启动整棵树后 dump `ctx.loader.entries()`。** 拒绝：启动会求值 `!!js` 表达式（把某台机器的环境泄漏进打印的配置）、以副作用启动适配器和会话、需要独立于 TTY 的拆卸路径，而且慢。dump 是用来调试合成的，而合成是那些文件的纯函数。
+
+**在 CLI 里重新实现补丁合并。** 拒绝：`applyPatches` 的第二个实现会与 vendored include 悄然漂移——这恰恰是该功能要调试的失败模式。导出 include 自己的算法只花费一条记录在案的 vendor 修改，却保证了同一性。
+
+**用 `/dump-config` TUI 命令代替标志。** 作为唯一形式被拒绝：主要用法是 `dsh --dump-config | diff - <(dsh --dump-default-config)` 这类管道工作流，需要免启动、非 TTY 的界面。之后可以在同一个 `renderConfigDump` 之上再加 TUI 命令。
+
+## Consequences
+
+配置调试从脑中重放补丁变成一条命令，支持工作也可以直接索要 `--dump-config` 输出。vendored include 多出一条记录在案的本地修改（导出 `applyEntryPatches`/`entryListSchema`；对挂载行为无影响），上游同步时需重新应用。来源追踪为每层重新合成一次前缀快照并按 JSON stringify 对行做 diff，因此 dump 有与层数²×行数成正比的额外开销；该开销只存在于免启动的 dump 路径。`renderConfigDump` 的单元测试覆盖层叠顺序、`!!js` 原样往返、来源分隔与分组、带标签的未匹配补丁警告，以及读取／解析／形状失败的大声报错；built-bin e2e 通过 `lib/bin.js` 驱动全部四种标志形式，包括个人覆盖层、其来源标签及其 stderr 警告。

 The TUI surface:
 
@@ -17,6 +17,8 @@ The TUI surface:
 
 `dsh upgrade` is a guided fresh-session entry over the default TUI surface: it mints a fresh session in the invoking directory and seeds its first turn with the bundled `dsh-upgrade` skill, exactly as if the user typed `/skill:<name>`. The launcher passes the skill name on the boot context ([`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)), which the TUI auto-invokes once the chat is live. Both take no options — `--config`, `-p`, and `--resume` fail loud — and seed only on this first launch, so a later `dsh --resume <id>` of the session is an ordinary TUI session with no re-injection.
 
+`dsh --dump-config` and `dsh web --dump-config` print the composed config tree — the shipped base, the surface overlay, and the `--config` or personal overlay, exactly the layers that surface would boot — as YAML on stdout and exit without booting; `--dump-default-config` stops at the surface overlay, so diffing the two shows precisely what the user layer changes. Each run of rows is preceded by a `# ==` comment naming the file it comes from and the layers that patched it (e.g. `# == base.cordis.yml, patched by tui.cordis.yml`), so the output shows provenance while staying one loadable document. Composition runs through the include's own patch algorithm and YAML dialect (`applyEntryPatches`/`entryListSchema` from `@cordisjs/plugin-include`), so the dump cannot drift from what boots; `!!js` expressions print verbatim and unevaluated, and a patch whose target row is absent is reported on stderr with its layer, mirroring the Loader's boot-time warning. Launcher-owned boot-context values (session identity, CLI-flag patches) are per-invocation facts outside the config tree and do not appear. The dump flags reject boot-only flags (`-p`, `--resume`, `--config-replace`) rather than silently ignoring them, and `--dump-default-config` takes no `--config`.
+
 The Web and headless surfaces boot `base.cordis.yml` plus `web.cordis.yml`, then apply `$DSH_HOME/config.yaml`; an explicit `--config <path>` replaces that personal overlay. Both surfaces otherwise share the same composition: 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, opt into first-message model titles, use the same bounded transient model-request retry policy as the TUI, and mount a disposable in-memory SQLite content-index service. That service is ACTIVE at boot, while its `node:sqlite` module and database handle open only on the first content search. This keeps Node 22 startup output free of SQLite's experimental warning before search is used; the first actual search may still emit the runtime warning. Each service instance owns its database, so parallel invocations neither share unsupported SQLite state nor leave derived index files behind, and the first search lazily reconciles live and persisted logs. 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`).
 
 The shipped TUI and Web compositions register the native DeepSeek adapter plus pi-ai OpenAI and Anthropic profiles. Credentials and endpoint overrides come from the provider-standard `DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`, `OPENAI_API_KEY` / `OPENAI_BASE_URL`, and `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL` pairs in the boot's layered environment.

 TUI 界面：
 
@@ -17,6 +17,8 @@ TUI 界面：
 
 `dsh upgrade` 是默认 TUI 界面之上的引导式全新会话入口：它在调用目录中创建一个全新会话，并以内置 `dsh-upgrade` skill 播种其首轮，效果等同于用户手动键入 `/skill:<name>`。启动器将 skill 名称提供到启动上下文（[`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)），TUI 在聊天就绪后自动调用它。两者都不接受任何选项——`--config`、`-p`、`--resume` 都会明确报错——且仅在首次启动时播种，因此之后 `dsh --resume <id>` 恢复该会话时是普通 TUI 会话，不会重复注入。
 
+`dsh --dump-config` 和 `dsh web --dump-config` 把合成后的配置树——已交付的基础配置、界面覆盖层，以及 `--config` 或个人覆盖层，恰好是该界面启动时组装的那些层——以 YAML 打印到 stdout 后退出，不启动任何东西；`--dump-default-config` 止步于界面覆盖层，因此对两份输出做 diff 就能精确看出用户层改了什么。每段连续的行之前都有一条 `# ==` 注释，标明该段来自哪个文件以及被哪些层修补过（例如 `# == base.cordis.yml, patched by tui.cordis.yml`），因此输出既展示来源，又仍是一份可加载的文档。合成通过 include 自己的补丁算法和 YAML 方言（`@cordisjs/plugin-include` 的 `applyEntryPatches`/`entryListSchema`）完成，因此 dump 不可能与实际启动漂移；`!!js` 表达式原样打印、不求值，目标行不存在的补丁会连同其所在层报到 stderr，与 Loader 启动时的警告一致。由启动器持有的启动上下文值（会话身份、CLI 标志补丁）是每次调用的事实，位于配置树之外，不会出现。dump 标志会拒绝仅用于启动的标志（`-p`、`--resume`、`--config-replace`）而不是静默忽略它们，`--dump-default-config` 不接受 `--config`。
+
 Web 和无头界面启动 `base.cordis.yml` 与 `web.cordis.yml`，随后应用 `$DSH_HOME/config.yaml`；显式的 `--config <path>` 会替代该个人覆盖。除此之外，两者共享同一套组合：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，选用首条消息模型标题，采用与 TUI 相同的有界暂时性模型请求重试策略，并挂载一个可丢弃的内存 SQLite 内容索引服务。该服务在启动时处于 ACTIVE 状态，但其 `node:sqlite` 模块与数据库句柄分别要到首次内容搜索才会导入和打开。这样可使 Node 22 在尚未使用搜索时的启动输出不出现 SQLite 实验性警告；首次实际搜索仍可能发出运行时警告。每个服务实例独占自己的数据库，因此并行调用既不会共享不受支持的 SQLite 状态，也不会留下派生索引文件，首次搜索还会惰性对账实时日志与持久化日志。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`）。
 
 已交付的 TUI 和 Web 组合会注册原生 DeepSeek 适配器，以及 pi-ai 的 OpenAI 和 Anthropic 提供方配置。凭据和端点覆盖来自启动分层环境中的提供方标准变量对：`DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`、`OPENAI_API_KEY` / `OPENAI_BASE_URL` 和 `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL`。

@@ -39,6 +39,7 @@ Keep this log exhaustive — every divergence from upstream must be listed.
 7. **`cordis/src/*.ts` JSDoc enrichment**: added `@param`/`@returns` tags and contract documentation (disposal semantics, waterfall veto, bail conditions, error cases) across the public plugin-author surface — `Context` (class, statics, and the `Context` interface properties incl. `root`), `EventsService`, `Fiber`, `RegistryService`, `ReflectService`, `Service`, `LoggerService` and their `declare module './context.ts'` overloads. Comment-only; no code changes. Motivation: the website API-reference generator renders these docs and hard-errors on undocumented members. Retire this entry when the enrichment is upstreamed to the fork.
 8. **`include/src/index.ts` hot-reload hardening**: `refresh()` awaits the full read-and-update and catches failures (logging a warning and keeping the last good entry tree) instead of rethrowing — upstream's throw escaped `@cordisjs/plugin-hmr`'s async watcher callback as an unhandled rejection, so one bad `cordis.yml` edit killed a live app. `read()` rejects a non-array parse result (an empty or mid-write truncated file parses to `undefined`, which upstream later crashed on) and commits `content`/`data` only on success, so reverting an edit to the exact last good content reads as "unchanged". `refresh()` and the `internal/update` listener re-apply `config.patches` before `root.update()`, matching initial load; upstream applied patches only in `[Service.init]`, so any config hot-reload silently reverted overlay-patched entries and removed inserted ones. `applyPatches` deep-copies via `structuredClone` instead of mutating the cached parse (repeated application converges; removing a patch reverts), and the veto-style `internal/update` listener persists the incoming config itself (`Fiber.update` only assigns behind `next()`), so later re-reads use the new patches. `[Service.init]` falls back to `initial` only on `ENOENT`; an existing-but-invalid file fails loud with its real parse error instead of "config file not found" (or a silent overwrite). `applyPatches` also indexes each `insert`ed entry as it is added, so a later patch in the same list can configure or disable a row an earlier patch inserted; upstream built the id index once before the patch loop, leaving inserted rows silently unpatchable. That matters because `dsh` composes one shared base (`apps/cli/config/base.cordis.yml`) with a surface overlay, an optional `--config` overlay, and the personal `~/.dsh/config.yaml` as sibling patch lists at one include level — patches never cross an include boundary, so surface-only rows would otherwise be unreachable from user config. Covered by `packages/ui/app-boot/tests/config-reload.spec.ts`.
 9. **Vendored Node-compatible TypeScript**: marked erased imports explicitly across `cordis`, `loader`, `include`, `hmr`, and `schemastery` so Node's native TypeScript transform does not request types as runtime exports. Schemastery's source uses an ESM default export and its package declares `type: module`; its built ESM/CJS entries retain explicit `.mjs`/`.cjs` extensions.
+10. **`include/src/index.ts` patch-semantics export**: extracted the private `applyPatches` body into the exported pure function `applyEntryPatches(data, patches, warn)` (the method delegates to it) and exported the `!!js` YAML dialect as `entryListSchema`, so `dsh --dump-config` composes and prints exactly what the include would mount without booting a tree. Behavior-preserving for mounting; the extraction exists because config tooling must never reimplement (and drift from) the patch algorithm.
