+# P1f · the host inside Tauri
+
+The native window is now self-contained.
+
+## Shape
+
+- `crates/zhila-daemon` became a library (`zhila_daemon::run(HostConfig)`) plus the thin daemon binary. `HostConfig` is port, token, no_audio and project.
+- `app/src-tauri` depends on the daemon library. On start it spawns one thread with a current-thread Tokio runtime and calls `run`; the Tauri window runs on the main thread. The engine, session, SQLite store, assets and WebSocket server live in the app process.
+- The embedded Svelte surface talks to `ws://127.0.0.1:4317` exactly as the browser does; the token is `dev`, the project is the default one.
+- The standalone daemon still exists for browser-first development; the two cannot share port 4317.
+
+## Verification
+
+- `cd app && ./node_modules/.bin/tauri build --no-bundle` builds `zhila-app` with the host; the release build passes.
+- The standalone daemon was stopped; `ss -ltnp` shows `zhila-app` owning `127.0.0.1:4317`.
+- The app log shows `project loaded ... descent-04`, the audio device, and `wire opened ... client=zhila-ui`; the window shows `engine live`, the project name, the 2 cores and the pattern.
+- Screenshot: `preview-p1-tauri-host.png`.
+- Final P1 checks: `./scripts/check.sh`, `node scripts/persistence-smoke.mjs` (manual cut + undo + redo across a daemon restart), the browser smokes.
+
+## Limits
+
+- The app uses the development token and the default project; no first-run project picker.
+- The app and the browser daemon contend for 4317.
+- WebKitGTK microphone permission for recording is not verified on this machine.
+- Installers (deb/AppImage) are still not built; the binary is the deliverable.
+
+## P1 acceptance
+
+The "first playing loop" is reachable end-to-end: import or record → sixteen faces, cut and trimmed by hand → assign to a vein → pattern plays → save/load, undo/redo across restarts → the same material and history in the self-contained native app.
