 # Agent Note: `dsh run` owns one-shot headless execution

 Status: implemented

 English | [中文](2026-08-08-dsh-run-headless-command.zh.md)

+> **Superseded command grammar.** [Apps now own their command lines](../architecture/2026-08-06-app-owned-command-line.md): the headless startup row parses the task from `dsh --profile headless <task...>`, and the launcher no longer has a `run` invocation or patches task text into rows. This note remains the rejected launcher-owned design context; the direct execution and completion contract it selected remains current in [headless is a direct core entry point](../architecture/2026-08-09-headless-direct-core-entry-point.md).
+
 ## Problem

 Generic profile boot and one-shot task execution have different lifecycle contracts. A root grammar that accepts optional task text makes one argv shape mean either a long-lived process or a terminating task according to a plugin row discovered only after composition. It also exposes a profile implementation detail as the primary user command and gives custom profiles no explicit one-shot entry.

 # Agent Note: `dsh run` 负责一次性 headless 执行

+> **命令语法已被取代。** [应用现在持有自己的命令行](../architecture/2026-08-06-app-owned-command-line.md)：headless 启动行从 `dsh --profile headless <task...>` 解析任务，启动器不再包含 `run` 调用，也不再把任务文本 patch 进配置行。本笔记保留被否决的启动器持有设计背景；它选定的直接执行与完成约定仍由 [headless 是直接 core 入口](../architecture/2026-08-09-headless-direct-core-entry-point.md)持有。

 ## 问题

 通用 profile 启动与一次性任务执行具有不同的生命周期约定。若根语法接受可选任务文本，同一种 argv 形态会表示常驻进程或终止式任务，具体含义取决于组合完成后才发现的插件配置行。它还会把 profile 实现细节暴露成主要用户命令，并使自定义 profile 缺少明确的一次性入口。

+# Agent Note: Apps own their command line through `ctx.cmdlineArgs`
+
+Status: implemented
+
+English | [中文](2026-08-06-app-owned-command-line.zh.md)
+
+## Problem
+
+After profiles, compositions were installable but their command lines were not. `apps/cli` still declared the Web flag family (`--host`, `--port`, `--dev`, `--workspace-root`, `--trusted-host`) and the one-shot task positional, then derived patches for row ids it hardcoded (`webserver`, `api-gateway`, `connection`, `web-runtime`). An out-of-tree app such as [turtle-ui](https://github.com/deepseek-harness/turtle-ui) could contribute rows but had no way to accept a flag: `dsh --profile tui --resume <session>` had nowhere to be parsed, and `dsh --profile web --help` printed the launcher's help rather than the web app's.
+
+## Decision
+
+The launcher parses only what it owns — `--profile`, `--patch`, the config dumps — and hands **everything after its own flags** to the booted tree verbatim. The split is positional: the first token the launcher does not recognize starts the app's arguments (commander's `passThroughOptions` + `allowUnknownOption` + `helpOption(false)`). A bare `dsh -h`, which has no app to hand the flag to, still prints the launcher's own help.
+
+The new `@deepseek-ai/dsh-cmdline` package owns the handoff. A launcher calls `provideCmdline(ctx, host)` before any entry mounts, providing `ctx.cmdlineArgs` (whose whole interface is `get(): readonly string[]`) and `ctx.appExit`. Any ordinary app plugin may inject `cmdlineArgs`, call `parseCmdline(ctx, program, plan)` with its own commander program, and provide the returned value as an app-owned service. Its Loader row carries no launcher marker or special kind, and the launcher does not inspect the composition for an owner. Multiple plugins may read the same immutable snapshot; a profile with no reader ignores its app arguments. Rows configured from a provider inject its service and read direct lazy config expressions (`port: !!js ctx.webStartup.port ?? 3080`), so a flag beats the value written beside it and nothing is written back into any row.
+
+The boot mounts the composition once. Cordis holds each row until its injections are active; Loader then interpolates that row's `!!js` against the injection-ready plugin context immediately before activation. Include keeps nested row expressions raw until their target row reaches this point. `--help` leaves the provider's service absent, so dependent rows never activate, and a live patch reload interpolates again against the service that remains active, so a served port cannot be silently reset.
+
+The shipped apps moved their flags into their bundles: `dsh-web-app` owns the Web family (and enables the `client-hmr` row it now ships disabled, for `--dev`), and `dsh-headless` owns the task positional and rejects a missing task as a usage error. `apps/cli/src/web.ts` is gone; `runProfile` no longer knows any flag-target row id. Out of tree, turtle-ui gained `--resume <session>` / `--session <id>` the same way, which is the design's real validation: an installed plugin added a flag with no launcher change.
+
+Two further consequences. Loader mounts sibling rows concurrently, so one row can activate while another still mounts or while the whole boot is rolling back; the Web bundle therefore publishes its URL only after its own Loader tree settles. The Web bundle's runtime plugin owns the harness-source prompt section too, so `dsh web` and `dsh --profile web` boot identically without Web-specific launcher setup.
+
+## Why Loader owns the ordering
+
+Four framework facts shape the mechanism:
+
+- **A profile's rows arrive inside the root include's `patches` option.** Include is an entry-tree owner, so its static entry-config resolver interpolates Include's own options while preserving nested `!!js` nodes for their target rows instead of recursively evaluating them in the Include context.
+- **Cordis activates a fiber only after all declared injections are active.** Immediately before each activation, Cordis runs the `internal/config` waterfall against the fiber's own context; Loader's listener interpolates the raw config after Cordis snapshots its injected services.
+- **Provider replacement and HMR must preserve the same contract.** Fiber reactivation re-runs the waterfall, HMR carries the raw config to the replacement fiber, and a pending row accepts option changes without prematurely evaluating expressions against absent services.
+- **A row cannot be inserted from inside a mounting plugin** — `tree.create` returns a prefixed id it then fails to resolve — so a conditional row ships `disabled: true` and an active row enables it (`dsh web --dev` and its reload chain). Enablement is an in-memory Loader override rather than an options rewrite, so Include reapplication cannot silently disable it. The Web bundle also starts client discovery only after enabling the optional row, ensuring the first browser graph already contains its HMR receiver.
+
+This leaves dependency ordering in Cordis activation and Loader interpolation, which own it. Rows keep their `inject` and config, Loader mounts the composition once, and the launcher only provides argv and process-lifecycle services.
+
+## Alternatives considered
+
+- **Writing the resolved values into each row** (a config update per row, plus a patch layer handed back to the launcher so a reload could not undo it): it worked, but it meant patches travelling from an app to the launcher and back, two mechanisms for one fact, and a recycle whose correctness depended on Loader restart internals. The maintainer rejected the round trip; the service the rows read replaced all of it.
+- **Releasing rows by clearing their `inject`**: it worked in isolation and failed on the real web tree, because clearing `inject` is exactly what loses the plugin's static injections. The failure is silent until a plugin reads a service it declared.
+- **Launcher-managed two-pass mounting**: it can make a provider active before readers are applied, but duplicates the composition, makes ordering a launcher concern, and conceals the Loader defect that nested expressions were evaluated in the include context rather than the target row's injected context.
+- **The launcher running each bundle's command function before boot** (no Cordis involvement): strictly earlier than "boot, then help", but it makes app startup a second plugin protocol outside the tree. An ordinary `cmdlineArgs`-injected provider keeps one protocol and remains dumpable and patchable.
+- **A launcher-enforced command-line owner**: rejecting zero or multiple readers would arbitrate overlaps such as `-h`, but `get()` is an immutable read and normal composition may need several app-owned services. Plugins therefore share the snapshot and own any parser interaction through ordinary composition.
+- **`instanceof CommanderError`**: an out-of-tree plugin brings its own commander copy, so the class identity differs and a printed `--help` was rethrown as a fatal load failure. Commander's control-flow errors are detected structurally instead.
+
+## Consequences
+
+- An app's flags, help text, and usage errors live with the rows they configure; adding a flag to an installed plugin needs no launcher change.
+- The launcher still recognizes the headless runner for one-shot process lifetime and the telemetry row for its environment switch; neither path interprets app arguments.
+- `--help` leaves every row that depends on the provider's service pending and requests bounded exit; unrelated rows may activate concurrently before teardown.
+- An app-owned service has no statically declared provider: a bundle shipping consumer rows without that provider fails at settlement with pending entries naming the service, not at load.
+- A user patch that replaces a row's whole `config` drops its expressions, and with them the flag's precedence for that row.
+- Launcher flags must precede app arguments; a first app argument equal to `web` or `plugin` selects that subcommand instead, `-V`/`--version` remains launcher-owned before that boundary, and the launcher's parser consumes one `--`, so a literal `--` for the app needs `-- --`.
+- `--dump-config` never runs app command-line providers, so it prints the composition before any app argument is resolved and rejects an invocation that carries app arguments.

+## 问题
+
+profile 落地之后，组合可以安装，命令行却不能。`apps/cli` 仍然声明着 Web flag 家族（`--host`、`--port`、`--dev`、`--workspace-root`、`--trusted-host`）和一次性任务位置参数，再为自己硬编码的行 id（`webserver`、`api-gateway`、`connection`、`web-runtime`）派生 patch。像 [turtle-ui](https://github.com/deepseek-harness/turtle-ui) 这样的树外应用能贡献行，却无处接受一个 flag：`dsh --profile tui --resume <session>` 没有地方可供解析，而 `dsh --profile web --help` 打印的是启动器的 help，而不是 web 应用的 help。
+
+## 决策
+
+启动器只解析属于自己的部分（`--profile`、`--patch`、配置 dump），并把**自己 flag 之后的一切**原样交给引导起来的配置树。切分按位置进行：启动器不认识的第一个 token 就是应用参数的起点（依靠 commander 的 `passThroughOptions` + `allowUnknownOption` + `helpOption(false)`）。裸的 `dsh -h` 没有可交付的应用，仍然打印启动器自己的 help。
+
+新包 `@deepseek-ai/dsh-cmdline` 持有这次交接。启动器在任何条目挂载之前调用 `provideCmdline(ctx, host)`，提供 `ctx.cmdlineArgs`（其全部接口就是 `get(): readonly string[]`）与 `ctx.appExit`。任何普通应用插件都可以注入 `cmdlineArgs`，用自己的 commander program 调用 `parseCmdline(ctx, program, plan)`，再把返回值作为应用自有服务提供出去。它的 Loader 行不携带启动器标记或特殊类型，启动器也不会检查组合中的所有者。多个插件可以读取同一份不可变快照；没有读取方的 profile 会忽略自己的应用参数。由提供方配置的行注入其服务，并在惰性配置表达式中直接读取它（`port: !!js ctx.webStartup.port ?? 3080`），因此 flag 胜过写在它旁边的值，也没有任何东西被写回任何一行。
+
+boot 只挂载一次整套组合。Cordis 让每一行等待其注入激活；Loader 随后在激活前一刻，基于已注入就绪的插件上下文插值该行的 `!!js`。Include 会保留嵌套的行表达式，直到目标行到达这一时点。`--help` 会让提供方服务保持缺失，因此依赖行永不激活；活动 patch 重载会针对仍然在线的服务再次插值，所以已经服务中的端口不会被悄悄重置。
+
+已交付的各应用把自己的 flag 搬进了组合包：`dsh-web-app` 持有 Web 家族（并为 `--dev` 启用它如今以禁用状态交付的 `client-hmr` 行），`dsh-headless` 持有任务位置参数，缺少任务时按用法错误拒绝。`apps/cli/src/web.ts` 已删除；`runProfile` 不再知道任何 flag 目标行 id。在树外，turtle-ui 以同样的方式获得了 `--resume <session>` / `--session <id>`，这才是这套设计的真正验证：一个已安装的插件加上了一个 flag，启动器毫无改动。
+
+还有两条后果。Loader 会并发挂载兄弟行，因此一行可能已经激活，而另一行仍在挂载，或整次 boot 正在回滚；所以 Web 组合包只会在自身的 Loader 配置树结算后公布 URL。另外，Web 组合包的运行时插件也持有 harness 源码提示词段，因此 `dsh web` 与 `dsh --profile web` 无需 Web 专用启动器设置即可按完全相同的方式启动。
+
+## 为什么由 Loader 持有顺序
+
+四条框架事实塑造了这套机制：
+
+- **profile 的各行位于根 include 的 `patches` 选项内部。** Include 是条目树所有者，因此它的静态条目配置解析器会插值 Include 自身的选项，同时为目标行保留嵌套的 `!!js` 节点，而不是在 Include 上下文中递归求值。
+- **Cordis 只在所有声明的注入都已激活后才激活 fiber。** 每次激活前一刻，Cordis 会基于 fiber 自身上下文运行 `internal/config` waterfall；Cordis 快照注入服务之后，Loader 的监听器再插值原始配置。
+- **提供方替换与 HMR 必须保持相同契约。** fiber 重新激活时会重跑 waterfall，HMR 会把原始配置带给替换 fiber，而待处理行可以接受选项变更，不会针对缺失服务提前求值表达式。
+- **不能从正在挂载的插件内部插入一行**——`tree.create` 返回一个带前缀的 id，随后它自己解析不出来——因此条件性的行以 `disabled: true` 交付，再由活跃行启用（`dsh web --dev` 及其重载链路）。启用采用 Loader 的内存覆盖而非改写选项，因此 Include 重新应用配置时不会悄然将其禁用。Web 组合包还会在启用可选行之后才启动客户端发现，确保首份浏览器图中已经包含 HMR 接收端。
+
+这样，依赖顺序仍由负责它的 Cordis 激活与 Loader 插值流程处理。各行保留自己的 `inject` 和配置，Loader 只挂载一次组合，启动器只提供 argv 与进程生命周期服务。
+
+## 曾考虑的替代方案
+
+- **把解析出的取值写进每一行**（逐行一次配置更新，外加交还给启动器的一层 patch，使重载无法撤销它）：它能工作，但这意味着 patch 在应用与启动器之间来回传递、同一件事有两套机制，以及一套其正确性依赖 Loader 重启内部细节的回收重建。维护者否决了这次往返；供各行读取的服务取代了这一切。
+- **通过清空行的 `inject` 来放行**：孤立测试可行，在真实 web 树上失败，因为清空 `inject` 恰恰会丢失插件的静态注入。在插件真的去读它声明过的服务之前，这个失败是静默的。
+- **由启动器管理两趟挂载**：它可以让提供方先于读取行激活，但会重复组合、把顺序变成启动器职责，还掩盖了 Loader 的缺陷——嵌套表达式在 include 上下文而不是目标行的注入上下文中求值。
+- **由启动器在 boot 之前运行每个组合包的命令函数**（完全不经过 Cordis）：严格早于「先 boot 再 help」，但这会让应用启动成为配置树之外的第二套插件协议。使用注入 `cmdlineArgs` 的普通提供方只保留一套协议，并且仍可 dump、可 patch。
+- **由启动器强制指定命令行所有者**：拒绝零个或多个读取方可以裁决 `-h` 等重叠项，但 `get()` 是不可变读取，普通组合也可能需要多个应用自有服务。因此插件共享该快照，并通过普通组合持有各自解析器的交互。
+- **`instanceof CommanderError`**：树外插件会带来自己的一份 commander 副本，类身份因此不同，已经打印出来的 `--help` 会被重新抛成致命的加载失败。改为按结构识别 commander 的控制流错误。
+
+## 后果
+
+- 应用的 flag、help 文本和用法错误与它们所配置的行放在一起；给已安装的插件加一个 flag 不需要改动启动器。
+- 启动器仍会识别 headless runner 以管理一次性进程生命周期，并识别 telemetry 行以应用环境开关；两条路径都不解析应用参数。
+- `--help` 会让所有依赖提供方服务的行保持待处理并请求有边界的退出；无关行可能在拆除前并发激活。
+- 应用自有服务没有静态声明的提供方：交付了消费行却缺少对应提供方的组合包会在结算时失败，报出指向该服务的待处理条目，而不是在加载时失败。
+- 用户 patch 若整体替换某行的 `config`，会连同其中的表达式一起丢掉，该行上 flag 的优先级也随之消失。
+- 启动器的 flag 必须写在应用参数之前；如果应用的第一个参数恰好等于 `web` 或 `plugin`，会选择对应的子命令；`-V`／`--version` 在该边界之前仍归启动器持有；而且启动器的解析器会消耗掉一个 `--`，因此要给应用传一个字面量 `--` 需要写成 `-- --`。
+- `--dump-config` 从不运行应用命令行提供方，因此它在任何应用参数被解析之前打印组合，并拒绝携带应用参数的调用。

 ## Problem

-The default telemetry mount added SIGINT/SIGTERM handlers to `dsh web` and the headless command (now `dsh run`) so process exit could drain the Cordis tree instead of dropping queued telemetry.

+The default telemetry mount added SIGINT/SIGTERM handlers to `dsh web` and the headless command (now `dsh --profile headless`) so process exit could drain the Cordis tree instead of dropping queued telemetry. Each handler used a one-way boolean latch and exited only after `ctx.fiber.dispose()` settled. Headless normal completion also awaited that disposal without a bound.

 A user then reproduced the headless command hanging immediately after the observation URL and ignoring repeated `Ctrl+C`; `DSH_TELEMETRY_DISABLED=1` removed the hang, while a standalone Node handler in the same Linux sandbox received SIGINT. This isolated the pending disposer to telemetry rather than terminal signal forwarding. OTel's `BatchLogRecordProcessor.shutdown()` awaits `exporter.forceFlush()` before the `exportTimeoutMillis`-bounded completion promise, and the OTLP exporter's `forceFlush()` waits directly on its in-flight HTTP Promise. A proxy/sandbox connection that never obtains a socket can therefore leave provider shutdown pending despite both configured SDK timeouts.

 随后有用户复现，headless 命令在打印观察 URL 后立即卡死，重复按 `Ctrl+C` 也没有反应；设置 `DSH_TELEMETRY_DISABLED=1` 后不再卡死，而同一 Linux 沙箱中的独立 Node 信号处理器能够收到 SIGINT。这将待结算的 disposer 定位到遥测，而非终端信号转发。OTel 的 `BatchLogRecordProcessor.shutdown()` 会先等待 `exporter.forceFlush()`，再进入受 `exportTimeoutMillis` 限制的完成 promise；OTLP 导出器的 `forceFlush()` 则直接等待正在进行的 HTTP Promise。因此，代理／沙箱连接始终无法取得 socket 时，即使已经配置两项 SDK 超时，也会让提供方关闭一直待结算。

It carried another executable, argument grammar, app composition, cancellation lifecycle, text/JSON/stream-JSON output contract, built artifact, documentation surface, and test suite.

The two entry points also assembled different trees, so a successful demo did not prove the shipped `headless` profile and users had to choose between overlapping commands.

 The replay suites still need canonical session events to pin assembled backend behavior. That testing need does not require a published command or compatibility contract.

 ## Decision

-Delete `@deepseek-ai/dsh-cli-demo` completely: its package, bin, parser, app plugin, output formats, tests, workspace references, generated-catalog entries, and active documentation. No alias or compatibility package remains. The root `demo:headless` script is retained only as a direct alias of `dsh run`; the product command owns final-text stdout, the observation URL on stderr, persistence, exit status, and shutdown.

No alias or compatibility package remains. The root `demo:headless` script is retained only as a direct alias of `dsh --profile headless`; the product command owns final-text stdout, failure diagnostics on stderr, persistence, exit status, and shutdown.

 `examples/headless-agent` becomes an explicit test composition. Its Loader configs mount `@deepseek-ai/dsh-agent-spine-demo`, one root agent, JSONL persistence, and checkpoint policy as separate rows instead of hiding them behind an app bundle. The support-tier `@deepseek-ai/dsh-loader-smoke` package owns the shared direct-agent turn helper; unexported example-local drivers select their Loader configuration and render canonical events as JSONL. They are launched only by tests, have no bin, and do not define a supported product output format.

 ## Alternatives considered

- **Keep `dsh-cli-demo` as an alias or wrapper around `dsh run`.** Rejected because a second bin and package would preserve two discoverable owners without adding capability.
- **Move JSON and stream-JSON flags onto `dsh run`.** Rejected because no current product consumer requires them; adopting the old demo protocol would enlarge the canonical CLI contract solely to save test machinery.

 ## Consequences

-This is intentionally breaking. `dsh-cli-demo`, its `--output-format` choices, and imports from `@deepseek-ai/dsh-cli-demo/src/cli.ts` no longer resolve. There is no public event-stream replacement in this change; callers use `dsh run` for one-shot execution and must choose an existing protocol surface when they need structured automation.

+## App arguments
+
+The launcher parses only its own flags and hands everything after them to the booted profile, where any injected app plugin may parse the shared immutable snapshot ([`dsh-cmdline`](../../packages/boot/cmdline/README.md)). Launcher flags therefore come first, and the first token the launcher does not recognize starts the app's arguments:
+
+```sh
+dsh --profile web --port 8080       # --port belongs to the web app
+dsh --profile tui --resume <id>     # --resume belongs to the terminal app
+dsh --profile headless "run the tests"
+dsh --profile web --help            # the web app's flags, not the launcher's
+dsh --help                          # the launcher's own help
+```

 ## Profiles

-A profile directory holds a `package.json` (out-of-tree plugin dependencies plus the profile manifest `dsh.profile` with its ordered `bundles` list) and a `cordis.patch.yml` (the user's own patch layer, hot-reloaded on long-lived surfaces). The tree composes over an empty root: each bundle's patch in `dsh.profile.bundles` order, then the profile's `cordis.patch.yml`, then the home-level `$DSH_HOME/cordis.patch.yml`, then `--patch` overlays, then flag patches. Bundles named in `dsh.profile.bundles` resolve from the dsh installation first (`@deepseek-ai/dsh-base`, `@deepseek-ai/dsh-web-app`, `@deepseek-ai/dsh-headless`), then from the profile's own `node_modules`, where pnpm installs out-of-tree plugins. Use `--dump-default-config` and `--dump-config` to inspect the composed tree without booting it.

 ## Profile boot

-`dsh --profile <name>` boots the profile at `$DSH_HOME/profiles/<name>`. The effective tree is composed over an empty root by applying, in order: each bundle patch named in the profile manifest's `dsh.profile.bundles` list, the profile's own `cordis.patch.yml`, the home-level `$DSH_HOME/cordis.patch.yml` (machine-local preferences shared by every profile, so it outranks the per-profile layer), each `--patch <path>` overlay in argv order, and launcher flag patches. Later layers win per row; a patch replaces the targeted row's complete `config` value rather than deep-merging keys, and may insert new rows. A parse, schema, resolution, or plugin boot failure is reported and exits nonzero. SIGINT and SIGTERM dispose the mounted root before exit.

A parse, schema, resolution, or plugin boot failure is reported and exits nonzero. SIGINT and SIGTERM dispose the mounted root before exit.

 Bundle names resolve from the dsh installation first, then from the profile directory. In-box bundles (`@deepseek-ai/dsh-base`, `@deepseek-ai/dsh-web-app`, `@deepseek-ai/dsh-headless`) therefore always come from the same installation as the running `dsh`; out-of-tree bundles come from the profile's pnpm-managed `node_modules`. A bare plugin `name` in any patch row resolves through the profile directory's Node parent-walk, which reaches the maintained installation fallback `$DSH_HOME/profiles/node_modules` (one symlink per package the installation's app and bundles depend on, healed on every launch).

-The `web` and `headless` profiles auto-initialize from shipped templates on first use (`web`: base + web-app; `headless`: base + headless). On load, the exact installation-owned headless tuple (base + web-app + headless) normalizes to the shipped template; extra, missing, or reordered bundle lists are user-owned and remain untouched. Any other missing profile fails loud with a hint to run `dsh plugin --profile <name> add <package>`.
+The `web` and `headless` profiles auto-initialize from shipped templates on first use (`web`: base + web-app; `headless`: base + headless). Any other missing profile fails loud with a hint to run `dsh plugin --profile <name> add <package>`.

-Profile boot accepts no positional task. A profile that mounts the one-shot runner row (`headless-runner`) therefore fails loud with the canonical `dsh run --profile <name> "<task>"` command instead of reaching the row's raw required-field error.
+### App arguments
+
+The launcher's flags come first and end at the first token it does not recognize; everything from there on is handed to the booted profile verbatim through `ctx.cmdlineArgs`, where any injected app plugin may parse it ([`dsh-cmdline`](../../../packages/boot/cmdline/README.md)). `dsh --profile web --port 8080` therefore reaches the web app's `--port`, `dsh --profile web --help` prints that app's help and boots nothing, and `dsh --help` (no profile to hand it to) prints the launcher's own. `-V`/`--version` prints the launcher's version when it appears before the app-argument boundary.
+
+A composition mounts once. An ordinary plugin injects `cmdlineArgs`, parses this app's arguments, and provides what it resolved as a service; each row configured from flags injects that service, and Loader waits for it before evaluating the row's config (`port: !!js ctx.webStartup.port ?? 3080`). A flag therefore beats the value written beside it. This precedence requires the row to retain that expression; a user patch that replaces the whole `config` with literals removes the runtime read. Help and rejected arguments request exit — nonzero for a rejection, 0 for help — without activating rows that depend on the provider's service. A live `cordis.patch.yml` edit re-evaluates expressions against services that are still up, so it cannot reset a served port.
+
+Launcher flags must come before app arguments, and the launcher's parser consumes one `--`: an app argument that must arrive as a literal `--` needs `-- --`. A first app argument equal to `web` or `plugin` selects that subcommand instead. `ctx.cmdlineArgs.get()` is a shared immutable read: multiple plugins may parse the same snapshot, while a profile with no reader ignores its app arguments.
+
+The shipped apps own these command lines:
+
+| Profile | Arguments |
+|---|---|
+| `web` | `--host`, `--port`, `--dev`, repeatable `--trusted-host` |
+| `headless` | the task text, as the positional argument |
+
+A one-shot task (`dsh --profile headless "run the tests"`) creates one fresh persisted Agent through the core registry, submits the task, waits for quiescence, and flushes the Session before deriving the last non-empty assistant text and final `turn/end` reason from its durable interval. It prints the text on stdout and exits 0 for `completed`, else 1. An invocation with no task is a usage error from that app. The shipped headless profile mounts no ApiProxy, Host, HTTP server, Web runtime, or browser client; a successful run writes nothing to stderr and opens no listening port.

 组合包名称先从 dsh 安装解析，再从 profile 目录解析。因此内置组合包（`@deepseek-ai/dsh-base`、`@deepseek-ai/dsh-web-app`、`@deepseek-ai/dsh-headless`）总是来自与正在运行的 `dsh` 相同的安装；树外组合包来自 profile 由 pnpm 管理的 `node_modules`。任何 patch 行中的裸插件 `name` 通过 profile 目录的 Node 父目录逐级查找解析，该查找可达到持续维护的安装后备目录 `$DSH_HOME/profiles/node_modules`（安装的应用和组合包所依赖的每个包对应一个符号链接，每次启动时修复）。

+
+一套组合只挂载一次。普通插件注入 `cmdlineArgs`、解析本应用参数，并把结果作为服务提供出去；由 flag 配置的每一行都会注入该服务，Loader 会等服务激活后再求值该行配置（`port: !!js ctx.webStartup.port ?? 3080`），因此 flag 胜过写在它旁边的值。该优先级要求配置行保留这一表达式；若用户 patch 用字面量替换整份 `config`，运行时读取也会随之消失。help 和被拒绝的参数会请求退出——拒绝时以非零状态，help 时以 0——且不会激活依赖提供方服务的行。在线编辑 `cordis.patch.yml` 会针对仍然在线的服务重新求值表达式，因此不会重置已在服务的端口。
+
+启动器的 flag 必须写在应用参数之前，且启动器的解析器会消耗掉一个 `--`：必须以字面量 `--` 送达应用的参数需要写成 `-- --`。如果应用的第一个参数恰好等于 `web` 或 `plugin`，会选择对应的子命令。`ctx.cmdlineArgs.get()` 是共享的不可变读取：多个插件可以解析同一份快照，没有读取方的 profile 则会忽略自己的应用参数。

 - **Unit** (`pnpm run test`): vitest over package and example specs under their `tests/**` directories plus repository script specs under `scripts/**/*.spec.ts`; tests stay with the code area they exercise. Every registry gets an HMR-safety test (dispose the contributing fiber, assert cleanup). Prefer edge cases, error paths, event ordering, concurrency races, and permanent tests for contract regressions (see `packages/core/agent-loop/tests/contract-regressions.spec.ts`).
 - **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. Per-file 100% on `packages/bash/pwsh-local/src` needs a real `pwsh`: without one its executor suites self-skip and `vitest.config.ts` exempts the file so pwsh-less hosts stay green, while CI runners ship pwsh and enforce the full bar.
 - **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 backend scenarios boot their explicit example composition through an unexported JSONL test driver, while `apps/cli` separately owns product `dsh run` acceptance. 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)).

 In-box bundle names always resolve from the dsh installation itself; pnpm manages only out-of-tree packages, so your bundle can rely on `@deepseek-ai/dsh-base` being present and current.

+## Give a surface bundle its own command line
+
+A bundle that defines a runnable app mounts an ordinary provider plugin:
+
+```yaml
+- id: hello-startup
+  name: 'dsh-hello-plugin/startup'
+```
+
+The plugin exports `inject = ['cmdlineArgs']`, calls `parseCmdline` from [`@deepseek-ai/dsh-cmdline`](../../../../packages/boot/cmdline/README.md) with its own commander program, and provides the returned value as its app-owned service. The launcher hands every plugin the same immutable arguments after launcher flags, so app-specific flags need no launcher change and multiple plugins may parse the snapshot. The Loader row needs no launcher marker or special kind.
+
+Rows configured by those arguments inject the provider's service and read it from their own `!!js` options, with the deployment value beside it as the fallback:
+
+```yaml
+- id: my-app
+  name: '@example/my-app'
+  inject: [myAppStartup]
+  config:

+# `@deepseek-ai/dsh-cmdline`
+
+English | [中文](README.zh.md)
+
+The command line a dsh launcher hands to the app it boots. The launcher parses only its own flags (`--profile`, `--patch`, the config dumps) and hands **everything after them** to the tree verbatim, so an app owns its flag family, its `--help` text, and its parse errors instead of the launcher knowing them.
+
+## The launcher values
+
+A launcher calls `provideCmdline(ctx, host)` before any tree entry mounts, which provides:
+
+- `ctx.cmdlineArgs` — the invocation's inner arguments. `get()` is the whole interface, and it returns a snapshot: `dsh --profile tui --resume abc` yields `['--resume', 'abc']`.
+- `ctx.appExit` — a bounded process-exit request, wired to the launcher's shutdown controller.
+
+An embedding host with no command line provides an empty list; that is the honest answer, not a missing value.
+
+## Ordinary providers and injected config
+
+Any app plugin may inject `cmdlineArgs`, parse it, and publish an ordinary app-owned service. `parseCmdline(ctx, program, plan)` is only a commander adapter; the caller owns the returned value and service:
+
+```ts ignore
+export const name = 'web-startup'
+export const inject = ['cmdlineArgs']
+
+export function apply(ctx: Context): void {
+  const values = parseCmdline(ctx, webCommand(), planWebStartup)
+  if (values !== undefined) ctx.provide('webStartup', values)
+}
+```
+
+Its Loader row carries no launcher marker or special kind:
+
+```yaml
+- id: web-startup
+  name: '@deepseek-ai/dsh-web-app/startup'
+```
+
+Every row configured from those values uses ordinary service injection and direct lazy config access:
+
+```yaml
+- id: webserver
+  name: '@deepseek-ai/dsh-host-webserver'
+  inject: [webStartup]
+  config:
+    host: !!js ctx.webStartup.host ?? '127.0.0.1'
+    port: !!js ctx.webStartup.port ?? 3080
+```
+
+`parseCmdline` parses the immutable arguments and asks `plan` for the app-owned value. On `--help`, `--version`, a parse error, or a `program.error(...)` from the plan, it writes commander's text, requests exit, and returns `undefined`; the provider publishes nothing, so dependent rows never activate.
+
+### How injection orders config
+
+Loader defers a row's `!!js` interpolation until that row's declared injections are active, then evaluates against the row's plugin context. The example above can therefore read `ctx.webStartup` directly: Cordis has already populated that injected service before Loader asks for `webserver`'s config. Include trees preserve nested expression nodes until each target row reaches this point. Provider replacement and live patch reload repeat interpolation against the current injected services, so a launch flag cannot be silently reset.
+
+`enableRow(ctx, id)` turns on a row a bundle ships disabled because only some invocations want it (`dsh web --dev` and its client-plugin reload chain). The activation is an in-memory override: it does not rewrite the row's configured `disabled` value and survives config reapplication for that mounted entry. Loader applies the enabled row's ordinary injection ordering.
+
+### Shared immutable arguments
+
+`get()` does not consume or mutate argv. Multiple plugins can parse the same snapshot and independently provide services. The launcher does not inspect the composition for a command-line owner; a profile with no reader simply ignores its app arguments.
+
+An out-of-tree plugin brings its own commander copy, so commander's control-flow errors are detected structurally rather than by class identity; an identity check would rethrow a printed help as a fatal load failure.
+
+## Model Experience
+
+None, as this package resolves the process's own command line before any session exists.
+
+#### KV Cache effect
+
+None; this package neither assembles nor sends a provider request.
+
+## Known Limitations and Deferred Work
+
+- **Launcher flags must precede app arguments.** The split is positional: the first token the launcher does not recognize starts the inner arguments, so `--patch` placed after an app flag belongs to the app. The launcher's parser consumes one `--`, so an app argument that must survive as a literal `--` needs `-- --`.
+- **An app-owned service has no statically declared provider.** Consumer rows name it through ordinary injection; a bundle that omits its provider fails at settlement with pending entries naming the service rather than at load.
+- **A user patch that replaces a row's whole `config` drops its expressions.** A flag beats the value written beside it, not a literal a user wrote in place of the expression; keeping the expression is what keeps the flag winning.

+
+## 启动器提供的值
+
+启动器在任何配置树条目挂载之前调用 `provideCmdline(ctx, host)`，它提供：

+```
+
+它的 Loader 行不携带启动器标记，也没有特殊类型：
+
+```yaml
+- id: web-startup
+  name: '@deepseek-ai/dsh-web-app/startup'
+```
+
+所有由这些取值配置的行都使用普通服务注入，并在惰性配置中直接访问该服务：
+
+```yaml
+- id: webserver
+  name: '@deepseek-ai/dsh-host-webserver'
+  inject: [webStartup]
+  config:
+    host: !!js ctx.webStartup.host ?? '127.0.0.1'
+    port: !!js ctx.webStartup.port ?? 3080
+```
+
+`parseCmdline` 解析不可变参数，再向 `plan` 索取应用自有取值。遇到 `--help`、`--version`、解析错误，或 `plan` 发出的 `program.error(...)` 时，它输出 commander 文本、请求退出并返回 `undefined`；提供方什么也不发布，因此依赖行不会激活。
+
+### 注入如何排列配置求值
+
+Loader 会把一行的 `!!js` 插值推迟到该行声明的注入全部激活之后，再基于该行的插件上下文求值。所以上例可以直接读取 `ctx.webStartup`：Loader 索取 `webserver` 的配置之前，Cordis 已经填入了这个注入服务。Include 树会保留嵌套表达式节点，直到各个目标行到达这一时点。提供方替换与活动 patch 重载都会针对当前注入服务重新插值，因此启动 flag 不会被悄悄重置。
+
+`enableRow(ctx, id)` 打开某个组合包以禁用状态交付、只有部分调用才需要的行（`dsh web --dev` 及其客户端插件重载链路）。该激活是内存中的覆盖：它不会改写行所配置的 `disabled` 值，并会在已挂载条目的配置重新应用后继续生效。Loader 会对启用后的行应用普通的注入顺序。
+
+### 共享不可变参数
+
+`get()` 不会消费或修改 argv。多个插件可以解析同一份快照，并分别提供服务。启动器不会检查组合中的命令行所有者；没有读取方的 profile 只会忽略自己的应用参数。
+
+树外插件会带来自己的一份 commander 副本，因此 commander 的控制流错误按结构识别，而不是按类身份识别；按身份判断会把已经打印出来的 help 重新抛成致命的加载失败。
+
+## 模型体验
+
+无。本包在任何会话存在之前解析进程自身的命令行。
+
+#### KV Cache 影响
+
+无；本包既不组装也不发送提供方请求。
+
+## 已知限制与延期工作
+
+- **启动器的 flag 必须写在应用参数之前**：切分按位置进行，启动器不认识的第一个 token 就是内层参数的起点，因此写在某个应用 flag 之后的 `--patch` 属于应用。启动器的解析器会消耗掉一个 `--`，因此必须以字面量 `--` 存活到应用的参数需要写成 `-- --`。
+- **应用自有服务没有静态声明的提供方**：消费行通过普通注入点名它；缺少提供方的组合包会在结算时失败，由待处理条目点名该服务，而不是在加载时失败。
+- **用户 patch 若整体替换某行的 `config`，会连同其中的表达式一起丢掉**：flag 胜过的是表达式旁写着的那个值，而不是用户用字面量替换掉表达式之后的结果；保留表达式才能保留 flag 的优先级。
