--   **Shared helpers over duplicated lambdas:** When `androidMain` and `jvmMain` contain identical pure-Kotlin logic (formatting, action dispatch, validation), extract it to a function in `commonMain`. Examples: `formatLogsTo()` in `feature:settings`, `handleNodeAction()` in `feature:node`, `findNodeByNameSuffix()` in `feature:connections`.
+-   **Shared helpers over duplicated lambdas:** When `androidMain` and `jvmMain` contain identical pure-Kotlin logic (formatting, action dispatch, validation), extract it to a function in `commonMain`. Examples: `formatLogsTo()` in `feature:settings`, `handleNodeAction()` in `feature:node`, `findNodeByNameSuffix()` in `feature:connections`, `MeshtasticAppShell` in `core:ui/commonMain`, and `BaseRadioTransportFactory` in `core:network/commonMain`.
 -   **KMP file naming:** In KMP modules, `commonMain` and platform source sets (`androidMain`, `jvmMain`) share the same package namespace. If both contain a file with the same name (e.g., `LogExporter.kt`), the Kotlin/JVM compiler will produce a duplicate class error. Use distinct filenames: keep the `expect` declaration in `LogExporter.kt` and put shared helpers in a separate file like `LogFormatter.kt`.
+-   **`jvmAndroidMain` source set:** Modules that share JVM-specific code between Android and Desktop apply the `meshtastic.kmp.jvm.android` convention plugin. This creates a `jvmAndroidMain` source set via Kotlin's hierarchy template API. Used in `core:common`, `core:model`, `core:data`, `core:network`, and `core:ui`.
+-   **Feature navigation graphs:** Feature modules export Navigation 3 graph functions as extension functions on `EntryProviderScope<NavKey>` in `commonMain` (e.g., `fun EntryProviderScope<NavKey>.settingsGraph(backStack: NavBackStack<NavKey>)`). Host shells (`app`, `desktop`) assemble these into a single `entryProvider<NavKey>` block. Do NOT define navigation graphs in platform-specific source sets.
 -   **Concurrency:** Use Kotlin Coroutines and Flow.
 -   **Dependency Injection:** Use **Koin Annotations** with the K2 compiler plugin (`koin-plugin` in version catalog). The `koin-annotations` library version is unified with `koin-core` (both use `version.ref = "koin"`). The `KoinConventionPlugin` uses the typed `KoinGradleExtension` to configure the K2 plugin (e.g., `compileSafety.set(false)`). Keep root graph assembly in `app`.
 -   **ViewModels:** Follow the MVI/UDF pattern. Use the multiplatform `androidx.lifecycle.ViewModel` in `commonMain`.

 - **Shared Tests First:** The majority of business logic, ViewModels, and state interactions are tested in the `commonTest` source set using standard `kotlin.test`.
 - **Coroutines Testing:** Use `kotlinx-coroutines-test` for virtual time management in asynchronous flows.
 - **Mocking Strategy:** Avoid JVM-specific mocking libraries. Prefer `Mokkery` or `Mockative` for multiplatform-compatible mocking interfaces, alongside handwritten fakes in `core:testing`.
+- **Platform-Specific Verification:** Use **Robolectric** on the Android host target to verify KMP modules that interact with Android framework components (like `Uri` or `Room`).
+- **Subclassing Pattern:** Maintain a unified test suite by defining abstract base tests in `commonTest` and platform-specific subclasses in `jvmTest` and `androidHostTest` for initialization (e.g., calling `setupTestContext()`).
 - **Flow Assertions:** Use `Turbine` for testing multiplatform `Flow` emissions and state updates.
 - **Property-Based Testing:** Use `Kotest` for multiplatform data-driven and property-based testing scenarios.

@@ -45,6 +45,54 @@ The `:core:testing` module is a dedicated **Kotlin Multiplatform (KMP)** library
 
 By centralizing fakes and mocking utilities here, we prevent duplication of test setups and enforce a standard approach to testing ViewModels, Repositories, and pure domain logic.
 
+## Handling Platform-Specific Setup (Robolectric)
+
+Some KMP modules interact with Android framework components (e.g., `android.net.Uri`, `androidx.room`, `DataStore`) that require Robolectric to run on the JVM. To maintain a unified test suite while providing platform-specific initialization, follow the **Subclassing Pattern**:
+
+### 1. Create an Abstract Base Test in `commonTest`
+Place your test logic in an abstract class in `src/commonTest`. Do NOT use `@BeforeTest` for setup that requires platform-specific context.
+
+```kotlin
+abstract class CommonMyViewModelTest {
+    protected lateinit var viewModel: MyViewModel
+    
+    // Call this from subclasses
+    fun setupRepo() {
+        // ... common setup logic
+    }
+    
+    @Test
+    fun testLogic() { /* ... */ }
+}
+```
+
+### 2. Implement the JVM Subclass in `jvmTest`
+A simple subclass is usually enough for pure JVM targets.
+
+```kotlin
+class MyViewModelTest : CommonMyViewModelTest() {
+    @BeforeTest
+    fun setup() {
+        setupRepo()
+    }
+}
+```
+
+### 3. Implement the Android Subclass in `androidHostTest`
+Use `@RunWith(RobolectricTestRunner::class)` and call `setupTestContext()` to initialize `ContextServices.app`.
+
+```kotlin
+@RunWith(RobolectricTestRunner::class)
+@Config(sdk = [34])
+class MyViewModelTest : CommonMyViewModelTest() {
+    @BeforeTest
+    fun setup() {
+        setupTestContext() // From :core:testing, initializes Robolectric context
+        setupRepo()
+    }
+}
+```
+
 ## Key Components
 
 - **Test Doubles / Fakes**: Provides in-memory implementations of core repositories (e.g., `FakeNodeRepository`, `FakeMeshLogRepository`) to isolate components under test.
