-Each provider has a corresponding mapper class (`OsrmRoute`, `ValhallaRoute`, `TomTomRoute`) that converts provider-specific JSON responses to the universal `Route` data model.
+Selection is driven by `RouteEngine` enum order (see `Data.kt`). `NavigationRepository` also exposes shared HTTP helpers (`fetchUrl`, `searchPlaces`, `reverseAddress`) that use Nominatim for geocoding and `ApplicationConfig`-backed HTTP basic auth for protected endpoints.
+
+Each provider has a corresponding mapper (`OsrmRoute`, `ValhallaRoute`, `TomTomRoute`) that converts provider-specific JSON into the universal `Route` model. The universal model is decomposed into a dedicated `data/route/` package: `Routes`, `Leg`, `Step`, `Maneuver`, `Intersection`, `Lane`, `Summary`.
 
 **Adding a new routing provider:**
-1. Create `NewProviderRepository` extending `NavigationRepository` in `common/data/src/main/java/com/kouros/navigation/data/`
-2. Implement `getRoute()` method
-3. Create `NewProviderRoute.kt` with `mapToRoute()` function
-4. Add provider detection logic in `Route.Builder.route()`

 ## Navigation Flow
 
-1. **Route Loading**: User searches via Nominatim → selects place → ViewModel.loadRoute() calls selected repository
-2. **Route Parsing**: Provider JSON → mapper converts to universal Route → RouteModel.startNavigation()
-3. **Location Tracking**: FusedLocationProviderClient provides updates → RouteModel.updateLocation()
-4. **Step Calculation**: findStep() snaps location to nearest waypoint → updates current step
-5. **UI Updates**: currentStep() and nextStep() provide display data (instruction, distance, icon, lanes)
-6. **Arrival**: When distance < DESTINATION_ARRIVAL_DISTANCE, navigation ends
+1. **Route loading** — User searches via Nominatim → selects place → `NavigationViewModel.loadRoute()` calls the selected repository
+2. **Route parsing** — Provider JSON → `*Route.mapToRoute()` populates `Route.Builder` → universal `Route` → `RouteModel.startNavigation()`
+3. **Location tracking** — `FusedLocationProviderClient` updates → `RouteModel.updateLocation()`
+4. **Step calculation** — `RouteCalculator.findStep()` snaps location to the nearest waypoint, returns `StepMatch`, and updates the current step index
+5. **UI updates** — `NavigationState` flows out via LiveData/Compose state; phone and car UIs render the current/next step (instruction, distance, icon, lanes)
+6. **Arrival** — When distance < `DESTINATION_ARRIVAL_DISTANCE`, navigation ends
 
 ## Testing Navigation
 
-The app includes mock location support for testing:
+The phone app supports mock locations for testing:
 
-- Set `useMock = true` in MainActivity
+- Set `useMock = true` in `MainActivity`
 - Enable "Mock location app" in Android Developer Options
-- Choose test mode:
-  - `type = 1` - Simulate movement along entire route
-  - `type = 2` - Test specific step range
-  - `type = 3` - Replay GPX track file
+- Choose mode in `model/Simulation.kt` / `model/MockLocation.kt`:
+  - `type = 1` — Simulate movement along the entire route
+  - `type = 2` — Test a specific step range
+  - `type = 3` — Replay a GPX track file
 
-## ObjectBox Database
+The car module has its own `navigation/Simulation.kt` for car-side simulation.
 
-ObjectBox is configured in `common/data/build.gradle.kts` with the kapt plugin. The database stores:
+### Unit tests
 
-- Recent destinations (category: "Recent")
-- Favorite places (category: "Favorites")
-- Imported contacts (category: "Contacts")
+- `common/data/src/test/.../model/RouteCalculatorTest.kt`
+- `common/data/src/test/.../model/RouteModelTest.kt`
+- `common/data/src/test/.../model/IconMapperTest.kt`
+- `common/data/src/test/.../model/OverpassTest.kt`
+- `common/data/src/test/.../utils/GeoUtilsTest.kt`
+- `common/car/src/test/.../screen/NavigationScreenTest.kt`
+- `common/car/src/test/.../screen/observers/CategoryObserverTest.kt`, `ObserversTest.kt`
 
-Queries use ObjectBox query builder pattern with generated `Place_` property accessors.
+## Persistence
+
+All app preferences are stored via Androidx **DataStore Preferences** (`navigation_settings` data store). There is no Room/ObjectBox/SQL database — the only persisted entities are settings and serialized lists (recent places, last route, last fuel prices) kept as strings.
+
+`DataStoreManager` exposes a `Flow<T>` per setting plus a matching `suspend set*` writer. `SettingsRepository` wraps it for higher-level access. `SettingsViewModel` and `AppViewModel` consume those flows for UI state.
 
 ## Compose UI Structure
 
-**Phone App:**
-- `MainActivity.kt` - Main entry with permission handling and Navigation Compose
-- `NavigationScreen.kt` - Turn-by-turn navigation display
-- `SearchSheet.kt` / `NavigationSheet.kt` - Bottom sheet content
-- `MapView.kt` - MapLibre rendering with camera state management
+**Phone app** (`app/src/main/java/com/kouros/navigation/`):
+- `ui/MainActivity.kt` - Entry point with permission handling and Navigation Compose host
+- `ui/MapView.kt` - MapLibre rendering with camera state management
+- `ui/SheetLayout.kt` - Bottom sheet scaffold
+- `ui/PermissionScreen.kt`
+- `ui/navigation/AppNavGraph.kt` - Compose navigation graph
+- `ui/navigation/NavigationScreen.kt`, `NavigationSheet.kt` - Turn-by-turn UI
+- `ui/search/SearchScreen.kt`, `SearchSheet.kt`
+- `ui/settings/SettingsScreen.kt`, `SettingsRoute.kt`, `DisplayScreen.kt`, `NavigationScreen.kt`, `CarScreen.kt`, `Settings.kt`
+- `ui/components/SettingItem.kt`, `SettingSwitch.kt`, `RadioButtonSingleSelection.kt`, `SectionTitle.kt`
+- `ui/app/AppViewModel.kt`, `AppViewModelProvider.kt`
+- `ui/theme/{Color,Type,Shapes,Theme}.kt`
+- `model/Simulation.kt`, `model/MockLocation.kt` - Mock location for testing
+- `di/appModule.kt` - Koin module
+- `MainApplication.kt` - Application class
 
-**Android Auto:**
-- Uses CarAppService Screen templates (NavigationTemplate, MessageTemplate, MapWithContentTemplate)
-- NavigationType enum controls which template to display (VIEW, NAVIGATION, REROUTE, RECENT, ARRIVAL)
+**Android Auto** uses CarAppService templates (NavigationTemplate, MessageTemplate, MapWithContentTemplate). `NavigationType` (in `screen/NavigationScreen.kt`) controls which template to render. UI state is synchronized with `NavigationViewModel` through the observers in `screen/observers/`.
 
 ## Build Flavors
 
-Two product flavors with dimension "version":
-- **demo** - applicationId: `com.kouros.navigation.demo`
-- **full** - applicationId: `com.kouros.navigation.full`
+`app/build.gradle.kts` defines three product flavors under the `store` dimension:
+- **play** - applicationIdSuffix `.play`
+- **demo** - applicationIdSuffix `.demo`
+- **full** - applicationIdSuffix `.full`
+
+Base namespace is `com.kouros.navigation`; current versionName is `0.3.0.109`. Java/Kotlin target is 21 for the app module, 11 for `common:data`. compileSdk/targetSdk = 37, minSdk = 33.
+
+`signing.properties` (root, gitignored) provides the keystore credentials for both debug and release builds. `local.properties` provides `USER` / `PASSWORD` build config fields consumed by `ApplicationConfig`.
 
 ## Common Patterns
 
-**Dependency Injection (Koin):**
+**Dependency injection (Koin):**
 ```kotlin
 single { OsrmRepository() }
-viewModel { ViewModel(get()) }
+viewModel { NavigationViewModel(get()) }
 ```
 
-**LiveData Observation:**
+**LiveData observation:**
 ```kotlin
 viewModel.route.observe(this) { routeJson ->
     routeModel.startNavigation(routeJson, context)
 }
 ```
 
-**Step Finding Algorithm:**
-RouteModel iterates through all step waypoints, calculates distance to current location, and snaps to the nearest waypoint to determine current step index.
+**Step-finding algorithm:**
+`RouteCalculator` iterates the current step's waypoints, calculates distance from the current location to each, and snaps to the nearest waypoint. Snap is rejected if the closest point exceeds `MAXIMAL_SNAP_CORRECTION`; deviation greater than `MAXIMAL_ROUTE_DEVIATION` triggers a reroute.
+
+**Settings flow:**
+```kotlin
+val darkMode by viewModel.darkMode.collectAsStateWithLifecycle()
+```
 
 ## Known Limitations
 
-- Valhalla route mapping is incomplete (search for TODO comments in ValhallaRoute.kt)
+- Valhalla route mapping is incomplete in places (search for TODO comments in `data/valhalla/ValhallaRoute.kt`)
 - Rerouting logic exists but needs more testing
-- Speed limit queries via Overpass API could be optimized for performance
-- TomTom implementation uses local JSON file (R.raw.tomom_routing) instead of live API
+- Speed-limit queries via Overpass API could be optimized for performance
+- TomTom and Tankerkönig clients have DEBUG-only `useLocal` shortcuts that hit fixture URLs (`http://192.168.1.37/...` and `R.raw.tomom_routing`) — these need to be off for any real-network testing
+- The `automotive` module is wired into Gradle but has no Kotlin source yet
