+# Specification: Extract Android Navigation graphs to feature modules for app thinning
+
+## Overview
+The primary goal of this track is to thin out the app module by moving the Android-specific navigation graph wiring (e.g., SettingsNavigation.kt, NodesNavigation.kt, ConnectionsNavigation.kt) into their respective feature modules (e.g., feature:settings, feature:node, feature:connections). This aligns the Android implementation with the Desktop application's architecture, where navigation logic is collocated with the features it routes.
+
+## Functional Requirements
+- **Target Modules:** Move all feature-specific navigation files from `app/src/main/kotlin/org/meshtastic/app/navigation/` to the `androidMain` source sets of their corresponding `feature:*` modules.
+- **Architecture:** Implement JetBrains Navigation 3 best practices for common usage across KMP modules. This involves ensuring the feature modules expose their navigation graphs seamlessly to the root NavHost in the app module, minimizing tight coupling.
+- **Root App Shell:** The app module should only retain the root MainActivity, the root DI graph assembly, and the top-level NavHost (e.g., MeshtasticApp.kt or similar entry point), calling into the feature modules' exposed graph functions.
+
+## Non-Functional Requirements
+- **Testability:** Add or update tests to verify that the complete navigation graph is correctly assembled from the individual feature modules without errors.
+- **Maintainability:** The extraction must preserve all existing deep links, arguments, and navigation transitions currently defined in the Android app.
+
+## Acceptance Criteria
+- [ ] The `app/src/main/kotlin/org/meshtastic/app/navigation/` directory only contains the root graph assembly.
+- [ ] All Android feature navigation graphs are successfully extracted to their respective `feature:*` modules.
+- [ ] The Android app compiles and runs successfully, with all navigation flows working identically to the previous implementation.
+- [ ] New graph assembly tests are added and pass in CI/local environments.

+# Specification: Extract remaining background services and workers from app module
+
+## Overview
+The primary goal of this track is to continue the app module thinning effort by extracting the remaining Android-specific background services, workers, and widgets from the `app` module into appropriate core or feature modules. Where possible, business logic from these components should be abstracted and moved to `commonMain` to support KMP targets. This will leave the app module as a thin entry point shell.
+
+## Functional Requirements
+- **Core Services:** Extract `AndroidMeshLocationManager.kt` and `MeshServiceClient.kt` to `core:service/androidMain`. Refactor underlying logic to `core:service/commonMain` where applicable.
+- **Messaging Workers:** Extract `WorkManagerMessageQueue.kt` to `feature:messaging/androidMain`. Analyze logic for potential `commonMain` abstraction.
+- **Widgets:** Extract the `LocalStatsWidget` implementation to a new or existing appropriate feature module (e.g. `feature:widget/androidMain`) following KMP feature module conventions.
+- **Dependency Injection:** Update the DI graph (`MainKoinModule.kt` / `AppKoinModule.kt`) to resolve these implementations from their new module locations using Koin compiler plugin annotations where applicable.
+
+## Non-Functional Requirements
+- **Testability:** Existing tests related to these services and workers should pass after relocation.
+- **Maintainability:** The extraction must preserve all existing app functionality, including background synchronization, location tracking, and widget updates.
+
+## Acceptance Criteria
+- [ ] `AndroidMeshLocationManager.kt` and `MeshServiceClient.kt` are successfully moved to `core:service`.
+- [ ] `WorkManagerMessageQueue.kt` is successfully moved to `feature:messaging`.
+- [ ] App Widgets are extracted out of the `app` module into an appropriate feature module.
+- [ ] Any logic that can be abstracted to `commonMain` has been extracted and shared.
+- [ ] `MainKoinModule.kt` is refactored, and DI wires everything correctly.
+- [ ] The Android app compiles and runs successfully, with background tasks and widgets working identically to the previous implementation.

-3. **Radio transport abstraction** — ✅ Done: Defined `RadioTransport` interface in `core:repository/commonMain` and replaced `IRadioInterface`; Next: continue extracting remaining platform transports from `app/repository/radio/` into core modules
-4. **`feature:connections` module** — ✅ Done: Extracted connections UI into KMP feature module with dynamic transport availability detection
-5. **Navigation 3 parity baseline** — ✅ Done: shared `TopLevelDestination` in `core:navigation`; both shells use same enum; parity tests in `core:navigation/commonTest` and `desktop/test`
-6. **iOS CI gate** — add `iosArm64()`/`iosSimulatorArm64()` to convention plugins and CI (compile-only, no implementations)
-7. **Build-logic consolidation** — ✅ Done: Created `meshtastic.kmp.feature` convention plugin (modelled after NiA's `AndroidFeatureImplConventionPlugin`). Composes `kmp.library` + `kmp.library.compose` + `koin` and wires common Compose/Lifecycle/Koin/androidMain deps. All 7 feature modules migrated; ~100 duplicated dep lines eliminated.
+1. **Evaluate KMP-native testing tools** — Evaluate `Mokkery` or `Mockative` to replace `mockk` in `commonMain` of `core:testing` for iOS readiness. Integrate `Turbine` for shared `Flow` testing.
+2. **Desktop Map Integration** — Address the major Desktop feature gap by implementing a raster map view using [**MapComposeMP**](https://github.com/p-lr/MapComposeMP).
+    - Implement a `MapComposeProvider` for Desktop.
+    - Implement a **Web Mercator Projection** helper in `feature:map/commonMain` to translate GPS coordinates to the 2D image plane.
+    - Leverage the existing `BaseMapViewModel` contract.
+3. **Unify `MapViewModel`** — Collapse the remaining Google and F-Droid specific `MapViewModel` classes in the `:app` module into a single `commonMain` implementation by isolating platform-specific settings (styles, tile sources) behind a repository interface.
+4. **iOS CI gate** — add `iosArm64()`/`iosSimulatorArm64()` to convention plugins and CI (compile-only, no implementations) to ensure `commonMain` remains pure.
 
 ## Medium-Term Priorities (60 days)
 
-1. **App module thinning** — Extracted ChannelViewModel, NodeMapViewModel, NodeContextMenu, EmptyDetailPlaceholder to shared modules.
-    - ✅ **Done:** Extracted remaining 5 ViewModels: `SettingsViewModel`, `RadioConfigViewModel`, `DebugViewModel`, `MetricsViewModel`, `UIViewModel` to shared KMP modules.
-    - ✅ **Done:** Extracted service, worker, and radio files from `app` to `core:service/androidMain` and `core:network/androidMain`.
-    - **Next:** Extract remaining Android-specific files (e.g., Navigation files, App Widgets, message queues, and root Activity logic) out of `:app` to establish a truly thin app module.
-2. ✅ **Done:** **Serial/USB transport** — direct radio connection on Desktop via jSerialComm
-3. **MQTT transport** — cloud relay operation (KMP, benefits all targets) ✅

-6. **Navigation contract extraction** — ✅ Done: shared `TopLevelDestination` enum in `core:navigation`; icon mapping in `core:ui`; parity tests in place. Both shells derive from the same source of truth.
-7. **Dependency stabilization** — track stable releases for CMP, Koin, Lifecycle, Nav3
+1. **iOS proof target** — Begin stubbing iOS target implementations (`NoopStubs.kt` equivalent) and setup an Xcode skeleton project.
+2. **`core:api` contract split** — separate transport-neutral service contracts from the Android AIDL packaging to support iOS/Desktop service layers.
+3. **Decouple Firmware DFU** — `feature:firmware` relies on Android-only DFU libraries. Evaluate wrapping this in a shared KMP interface or extracting it to allow the core `feature:firmware` module to be utilized on desktop/iOS.

-2. **Platform-Native UI Interop** — 
+1. **Platform-Native UI Interop** — 
    - **iOS Maps & Camera:** Implement `MapLibre` or `MKMapView` via Compose Multiplatform's `UIKitView`. Leverage `AVCaptureSession` wrapped in `UIKitView` to fulfill the `LocalBarcodeScannerProvider` contract.
-   - **Desktop Maps:** Implement maps via `SwingPanel` wrapper, utilizing experimental interop blending (`compose.interop.blending=true`) to ensure tooltips and Compose overlays render correctly on top of the native JComponent.
    - **Web (wasmJs) Integrations:** Leverage `HtmlView` to embed raw DOM elements (e.g., `<video>`, `<iframe>`, or canvas-based maps) directly into the Compose UI tree while binding the root app via `CanvasBasedWindow`.
