-The production Web runner needs built package and frontend artifacts (`pnpm run build`). It serves `http://127.0.0.1:3080` by default. Binding all interfaces also trusts the machine's discovered LAN IP literals; `--trusted-host` adds named authorities accepted by the `/api` browser-trust fence.
+The production Web runner needs built package and frontend artifacts (`pnpm run build`). It serves `http://127.0.0.1:3080` by default. The CLI intentionally does not support `--host 0.0.0.0` yet and exits with a usage error; `--trusted-host` adds named authorities accepted by the `/api` browser-trust fence.
 
 Process shutdown gives the plugin tree up to five seconds to dispose. The first `SIGINT`/`SIGTERM` starts that graceful drain — `SIGTERM` is a supervisor's ordinary stop request and exits 0 on every surface, `SIGINT` reports 130; a second signal forces immediate exit. If one-shot normal completion is already stuck in disposal, the first `Ctrl+C` is the escalation and exits immediately instead of being swallowed.

 进程关闭时，插件树最多有 5 秒完成 dispose。首次收到 `SIGINT` 或 `SIGTERM` 时会开始优雅排空：`SIGTERM` 是监督进程发出的常规停止请求，在所有运行模式下都以 0 退出；`SIGINT` 则报告 130。第二次收到信号时会立即强制退出。如果一次性运行在正常结束时已经卡在 dispose 阶段，第一次按下 `Ctrl+C` 就会直接升级为强制退出，而不会被忽略。

-The dsh browser-surface bundle. [`cordis.patch.yml`](cordis.patch.yml) rides over [`dsh-base`](../base/README.md): it sets the coding persona, inserts the Web host rows (webserver, API gateway, workspace, projection cache, storage) and the browser plugin roster, the always-on client-plugin reload chain ([`dsh-client-hmr`](../../client/hmr/README.md), idle until a rebuild watcher rewrites client bundles), and mounts this package's `web-runtime` glue plugin (config `{printUrl, surfaceContext, trustedHosts}`). That plugin resolves the built frontend dist through `@deepseek-ai/dsh-web-frontend`'s exports, samples bind-dependent LAN trust once, provides it as `webRuntime` to the browser-trust fence and client roster, mounts the [`frontend-static`](../../host/frontend-static/README.md) fallback owner, registers the harness-source and web-surface prompt sections plus the bash-visible `DSH_WEB_URL` runtime variable when `surfaceContext` is true, and prints the `dsh web:` URL line when `printUrl` is true, after its Loader tree settles so a sibling failure cannot announce a dead app. This bundle also owns the app command line: the ordinary `web-startup` provider ([`src/startup.ts`](src/startup.ts)) injects `ctx.cmdlineArgs` ([`dsh-cmdline`](../../boot/cmdline/README.md)), parses `--host`, `--port`, repeatable `--trusted-host`, and the app's `--help`, then provides `webStartup`. Flag-configured rows inject that service and read it directly from lazy config, so nothing binds a port before argument resolution and `dsh --profile web --help` starts no server. [`dsh-headless`](../headless/README.md) is a sibling surface over the same base and does not mount this bundle.
