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`. It rejects `--host 0.0.0.0` before publishing that service because the CLI intentionally does not support all-interfaces binding yet. Flag-configured rows inject the 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.
When `surfaceContext` is true, the `harness:source` section identifies the on-disk Harness implementation without claiming it is the working directory, and the `app:web-surface` global section (order −98) orients the model to the GUI: the canonical local URL, the "this page" referent, the update contract (the reload receiver is always on; no-refresh reloads additionally need the `pnpm run dev:web` watcher), and the instruction not to start replacement servers. `DSH_WEB_URL` additionally appears in the managed bash environment with its description, resolved per invocation from the live server. When it is false, neither section nor the variable is registered.
The prompt section sits near the system prompt's head and is stable for the life of the process (the port is a boot fact), so it does not invalidate the cache across turns.
- **The frontend dist must be built** — `require.resolve` of the dist fails loud at activation with a build hint; there is no source-serving fallback.
- **`lanAddresses` is a boot-time snapshot** — interface changes after boot are not re-advertised; the printed LAN URL always matches the configured trust fence.
