### 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 that app's own startup row parses 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.
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. A Loader row that 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 startup 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. A profile with no active row injecting `cmdlineArgs` accepts no app arguments; it rejects them before mounting any row instead of silently ignoring them. A composition with multiple active rows injecting `cmdlineArgs` is always rejected because two parsers cannot own the same command line.

`dsh web` is a hardcoded alias for `--profile web`; the flags after it belong to the web app, which owns them in its bundle's startup row. `--host` and `--port` override the composed values of the rows that carry them, repeatable `--trusted-host` adds authorities over the composed fence configuration, and `--dev` switches the web-runtime row to development mode and enables the client-plugin HMR receiver the bundle ships disabled; it expects a separate `pnpm run dev:web` watcher for no-refresh client bundle updates.

### 应用参数
启动器自己的 flag 写在最前面,并在它不认识的第一个 token 处结束;从那里开始的一切都通过 `ctx.cmdlineArgs` 原样交给启动起来的 profile,由该应用自己的启动行解析([`dsh-cmdline`](../../../packages/boot/cmdline/README.md))。因此 `dsh --profile web --port 8080` 到达的是 web 应用的 `--port`,`dsh --profile web --help` 打印的是该应用的 help 且什么也不启动,而 `dsh --help`(没有可以交付的 profile)打印的是启动器自己的 help。`-V`/`--version` 写在应用参数边界之前时会打印启动器的版本。
启动器自己的 flag 写在最前面,并在它不认识的第一个 token 处结束;从那里开始的一切都通过 `ctx.cmdlineArgs` 原样交给启动起来的 profile,任何注入它的应用插件都可以解析([`dsh-cmdline`](../../../packages/boot/cmdline/README.md))。因此 `dsh --profile web --port 8080` 到达的是 web 应用的 `--port`,`dsh --profile web --help` 打印的是该应用的 help 且什么也不启动,而 `dsh --help`(没有可以交付的 profile)打印的是启动器自己的 help。`-V`/`--version` 写在应用参数边界之前时会打印启动器的版本。
一套组合只挂载一次。注入 `cmdlineArgs` 的 Loader 行解析本应用参数,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——且不会激活依赖启动服务的行。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``plugin`,会选择对应的子命令。若 profile 中没有注入 `cmdlineArgs` 的活跃行,该 profile 不接受应用参数;启动器会在挂载任何行之前拒绝这些参数,而不是静默忽略。若组合中有多个注入 `cmdlineArgs` 的活跃行,启动器总会拒绝该组合,因为两个解析器不能共同持有同一条命令行
