 - [x] Release signing key: `android/keystore/release.keystore` (gitignored) + `keystore.properties`
 - [x] ProGuard/R8 rules verified — release APK builds AND launches on the Pixel
 - [x] APK output: `app/build/outputs/apk/release/app-release.apk` (~43 MB, signed)
-- [ ] Self-hosted distribution:
-  - Copy APK to Pi: `scp app-release.apk [email protected]:~/app/yaris-obd/static/app/`
-  - Add a lightweight Pi route: `GET /app` → serves `static/app/index.html` with
-    download link + install instructions
-  - Phone flow: connect to Pi hotspot → open `http://yaris.local/app` → download APK →
-    install (user must enable "Install unknown apps" once)

+- [x] Self-hosted distribution (server → Pi → phone):
+  - Server: `GET /api/v1/app/latest` (public version+sha256) + `GET /app/yaris-obd.apk`
+    (download) + `GET/POST /app/upload` (portal page to publish a build)
+  - Pi: `GET /app` (download page) + `GET /app/yaris-obd.apk`; `deploy/yaris_app_updater.py`
+    mirrors the latest APK from the server on a systemd timer
+    (`deploy/yaris-app-updater.{service,timer}` + `deploy/install_app_updater.sh`)
+  - Phone: connect to hotspot → `http://10.42.0.1/app` → download → install
+- [ ] Deploy: run `install_app_updater.sh` on the Pi; publish a build via the portal (or scp
+      the APK into the server's mounted `dashcam/app/` volume)
