- `fdroid`: Open source only, no tracking/analytics.
- `google`: Includes Google Play Services (Maps) and DataDog analytics.
- **Core Architecture:** Modern Android Development (MAD) with KMP core.
- **KMP Modules:** Most `core:*` modules. All declare `jvm()` target and compile clean on JVM.
- **KMP Modules:** Most `core:*` modules. All declare `jvm()`, `iosArm64()`, and `iosSimulatorArm64()` targets and compile clean across all.
- **Android-only Modules:** `core:api` (AIDL), `core:barcode` (CameraX + flavor-specific decoder). Shared contracts abstracted into `core:ui/commonMain`.
- **UI:** Jetpack Compose Multiplatform (Material 3).
- **DI:** Koin Annotations with K2 compiler plugin. Root graph assembly is centralized in `app` and `desktop`.

## 3. Development Guidelines & Coding Standards
### A. UI Development (Jetpack Compose)
- **Material 3:** The app uses Material 3.
- **Strings:** MUST use the **Compose Multiplatform Resource** library in `core:resources` (`stringResource(Res.string.your_key)`). NEVER use hardcoded strings.
- **Strings:** MUST use the **Compose Multiplatform Resource** library in `core:resources` (`stringResource(Res.string.your_key)`). For ViewModels or non-composable Coroutines, use the asynchronous `getStringSuspend(Res.string.your_key)`. NEVER use hardcoded strings, and NEVER use the blocking `getString()` in a coroutine.
- **Dialogs:** Use centralized components in `core:ui` (e.g., `MeshtasticResourceDialog`).
- **Platform/Flavor UI:** Inject platform-specific behavior (e.g., map providers) via `CompositionLocal` from `app`.
