+## v1 Completion Plan
+
+Scaffold is done (all screens, navigation, store, services, GPX, DB, upload).
+Items below are what remains before v1 is shippable.
+
+### 1 — Quick fixes (each < 30 min)
+
+- [ ] **Keep-awake toggle** — `useKeepAwake()` in `RecordingScreen` is unconditional; wire it to `keepAwake` from the store so the toggle actually works
+- [ ] **Sensor button on Recording screen** — no entry point to the SensorPairing modal; add a BLE icon button in the header or stats area that calls `nav.navigate('SensorPairing')`
+- [ ] **GPS pause/resume** — `pause()` / `resume()` only change store state; also call `stopGpsRecording()` / `startGpsRecording()` so the background task actually pauses
+
+### 2 — BLE (half day)
+
+- [ ] **Android runtime permissions** — `BLUETOOTH_SCAN` + `BLUETOOTH_CONNECT` require explicit permission requests on Android 12+; add a `requestBlePermissions()` call in `SensorPairingScreen` before scanning
+- [ ] **Cadence CSC parsing** — `subscribeCadence()` in `ble.ts` is stubbed; implement stateful CSC Measurement parsing (track previous crank revolution count + timestamp, compute RPM from delta)
+- [ ] **BLE persistence** — save paired device IDs + types to AsyncStorage on connect; on app start, attempt to reconnect to previously paired devices automatically
+
+### 3 — Km notifications (half day)
+
+- [ ] **Permission request** — call `Notifications.requestPermissionsAsync()` on first launch
+- [ ] **Milestone tracker** — track last notified km in the GPS background task (or store); fire a notification each time `distanceMeters` crosses a new km boundary, gated on the `kmNotifications` setting from AsyncStorage
+
+### 4 — Android battery optimization prompt (1–2 hours)
+
+- [ ] On first launch, detect if the app is affected by battery optimization (`expo-intent-launcher`) and show a one-time prompt directing the user to whitelist bincio-rec; persist dismissal in AsyncStorage so it only shows once
+
+### 5 — Map (1–2 days)
+
+- [ ] **Initialize MapLibre** — call `MapLibreGL.setAccessToken(null)` at app start (or configure a tile provider in Settings); add a tile source (e.g. OpenFreeMap / self-hosted)
+- [ ] **Replace placeholder** — swap the grey `<View>` in `RecordingScreen` with a `<MapLibreGL.MapView>` + `<MapLibreGL.Camera>` that follows current location
+- [ ] **Live track polyline** — subscribe to `trackPoints` from the store and render a `<MapLibreGL.ShapeSource>` + `<MapLibreGL.LineLayer>` that updates as points arrive
