+# Implementation Plan: Extract Remaining App-Only ViewModels
+
+## Phase 1: Infrastructure & Abstractions
+- [ ] Task: Implement `MeshtasticUri` (expect/actual wrapper for `android.net.Uri`) in `core:common`.
+- [ ] Task: Define `FileService` and `LocationService` interfaces in `core:repository/commonMain`.
+- [ ] Task: Create Android implementations for these services in `core:service/androidMain`.
+- [ ] Task: Conductor - User Manual Verification 'Phase 1: Infrastructure & Abstractions' (Protocol in workflow.md)
+
+## Phase 2: Feature Module Extractions (Settings & Node)
+- [ ] Task: Extract `AndroidSettingsViewModel` & `AndroidRadioConfigViewModel` to `feature:settings/commonMain`.
+- [ ] Task: Extract `AndroidMetricsViewModel` to `feature:node/commonMain`.
+- [ ] Task: Extract `AndroidDebugViewModel` to `feature:settings/commonMain`.
+- [ ] Task: Update Koin modules in `feature:settings` and `feature:node` to wire the new shared ViewModels.
+- [ ] Task: Conductor - User Manual Verification 'Phase 2: Feature Module Extractions' (Protocol in workflow.md)
+
+## Phase 3: Core UI & Cleanup
+- [ ] Task: Extract `UIViewModel` logic to `core:ui/commonMain`.
+- [ ] Task: Verify the `app` module thinning progress and finalize any remaining DI cleanup in `AppKoinModule`.
+- [ ] Task: Ensure all new shared ViewModels have baseline `commonTest` coverage using `core:testing` fakes.

+# Specification: Extract Remaining App-Only ViewModels
+
+## Overview
+This track aims to migrate the final 5 ViewModels currently trapped in the `app` module to their respective KMP `feature:*` or `core:*` modules. These ViewModels contain business logic that should be shared across platforms, but are currently coupled to Android-specific APIs.
+
+## Functional Requirements
+- **Isolate Dependencies:** Identify and abstract Android-specific APIs using a hybrid approach (expect/actual for low-level types and injected interfaces for services).
+- **Relocate ViewModels:** Move the core logic of these ViewModels to `commonMain` in the target modules:
+    - `SettingsViewModel` & `RadioConfigViewModel` -> `feature:settings`
+    - `DebugViewModel` -> `feature:settings`
+    - `MetricsViewModel` -> `feature:node`
+    - `UIViewModel` logic -> `core:ui`
+- **Dependency Injection:** Update Koin modules to provide platform-specific implementations of the abstracted interfaces.
+- **Maintain Parity:** Ensure existing functionality is preserved on Android while enabling these features on Desktop.
+
+## Acceptance Criteria
+- All 5 ViewModels are extracted from the `app` module and logic resides in `commonMain`.
+- `commonTest` coverage is established for the shared logic in each respective module.
+- The `app` module file count is further reduced.
+- Desktop target can instantiate and use the shared ViewModels.
