Turtle 2365b2c54f feat(bundle): ship dsh-base, dsh-web-app, and dsh-headless profile bundles
Profile bundles are npm packages declaring dsh.patch in their manifest:
dsh-base carries the former base.cordis.yml rows as one insert over the empty
profile root; dsh-web-app carries the web overlay plus a runtime glue plugin
owning what used to be launcher code (frontend dist resolution via
frontend-static, the web-surface prompt section, bash runtime variables, the
readiness-gated URL line); dsh-headless carries the one-shot runner driving a
task turn through the in-process API carrier under the launcher-provided
ctx.headlessIo seam.

# `@deepseek-ai/dsh-web-app`
English | [中文](README.zh.md)
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, storage) and the browser plugin roster, and mounts this package's own `web-runtime` glue plugin (config `{mode, printUrl, lanAddresses}`). That plugin owns what used to be launcher code: it resolves the built frontend dist through `@deepseek-ai/dsh-frontend`'s exports (workspace knowledge of this bundle, never user config), mounts the [`frontend-static`](../../host/frontend-static/README.md) fallback owner over it, registers the web-surface prompt section and the bash-visible `DSH_WEB_URL`/`DSH_WEB_MODE` runtime variables, and prints the `dsh web:` URL line when `printUrl` is true. The `dsh web` launcher alias patches `mode`/`lanAddresses`/`printUrl` and the flag family over these rows; [`dsh-headless`](../headless/README.md) layers on top and silences the URL line.
## Model Experience
### Web-surface prompt section and bash runtime variables
#### What the model sees
The `app:web-surface` global section (order 98) orients the model to the GUI: the canonical local URL, the "this page" referent, the HMR/rebuild update contract for the active mode, and the instruction not to start replacement servers. `DSH_WEB_URL` and `DSH_WEB_MODE` additionally appear in the managed bash environment with their descriptions, resolved per invocation from the live server.
#### Token effect
One prompt paragraph per session plus two managed-environment variable lines; constant per process.
#### KV Cache effect
The prompt section sits near the system prompt's head and is stable for the life of the process (port and mode are boot facts), so it does not invalidate the cache across turns.
## Known Limitations and Deferred Work
- **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.
