 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.

 一套组合只挂载一次。注入 `cmdlineArgs` 的 Loader 行解析本应用的参数，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` 或 `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。
