## Native Android app (waiter_pwa)
The same waiter code, bundled into an APK with Capacitor 8. It is sideloaded, not on Play Store yet.
```powershell
cd waiter_pwa
npm run apk:debug # releases/xenia-waiter-<ver>-debug.apk (WebView debuggable via chrome://inspect)
npm run apk:release # releases/xenia-waiter-<ver>.apk, signed, AND copied to public/downloads/
```
- **Signing key:** `%USERPROFILE%\.xenia\xenia-release.jks` + `keystore.properties`. It lives **outside the repo; back it up.** A lost key means no phone can install updates (uninstall and reinstall on every phone). Cert SHA-256 `98:A2:60:25:…:61:7A`.
- **Versioning:** bump **both** `versionCode` and `versionName` in `android/app/build.gradle` for every APK handed out. Android refuses an update whose versionCode isn't higher.
- **Distribution:** `apk:release` copies the APK into `public/downloads/`, so the next web build (and Docker image) serves it at `http://<IP>/downloads/xenia-waiter.apk`. The browser-mode install banner links there. **Order: `apk:release` → `docker compose … build`.**
- **Native specifics:**
- `androidScheme: http` (origin `http://localhost`)
- cleartext allowed via `network_security_config.xml`
- no service worker (`vite build --mode native` → `dist-native/`)
- back button handled in `src/native/backButton.js`
- first run shows only the pairing screen
- `android/local.properties` (SDK path) is gitignored. Recreate it on a new machine: `sdk.dir=C:/Users/<you>/AppData/Local/Android/Sdk`.
**CS-9. Anything a native build needs must survive `npx cap sync`.**
`android/app/src/main/assets/public` and the generated configs are rebuilt on every sync, so never edit them. Native changes go in `android/app/src/main/**` (manifest, res, java) or `capacitor.config.json`.
## Testing
There is no automated test suite yet. Before committing:
- the backend starts cleanly against an **existing** `pos.db` (this catches missing migrations)
