- Create a composite GitHub Action `gradle-setup` to encapsulate code checkout, wrapper validation, JDK 21 setup, and Gradle caching logic.
- Update all GitHub workflows (`publish-core`, `codeql`, `scheduled-updates`, `release`, etc.) to utilize the new centralized `gradle-setup` action.
- Upgrade the project's primary JDK requirement from 17 to 21 across `jitpack.yml`, workflow files, and build-logic conventions.
- Refactor `KotlinAndroid.kt` and `build.gradle.kts` to target JVM 21 for the application while maintaining JVM 17 compatibility for published library modules (`api`, `model`, `proto`).
- Introduce a new `build-desktop` job in `reusable-check.yml` to verify desktop artifact assembly during CI.
- Implement dynamic `cache_read_only` detection in workflows to optimize Gradle cache usage across different branch types and merge groups.
- Update project documentation (`GEMINI.md`, `AGENTS.md`, `CONTRIBUTING.md`) to reflect the JDK 21 requirement and provide guidance on Robolectric configuration for the new version.
- Introduce `MeshtasticNavDisplay` in `core:ui` to encapsulate shared Navigation 3 configuration, including entry decorators, scene strategies, and transitions.
- Integrate `rememberViewModelStoreNavEntryDecorator` to provide entry-scoped `ViewModelStoreOwner` support, ensuring ViewModels are automatically cleared when their backstack entry is popped.
- Configure `DialogSceneStrategy` to enable navigation-driven dialogs that respect backstack lifecycle and predictive back gestures.
- Implement a standardized 350 ms crossfade transition for both forward and pop navigation across all platforms.
- Refactor `app` and `desktop` host modules to utilize `MeshtasticNavDisplay`, removing redundant manual configuration of `NavDisplay` and decorators.
- Update `core:ui` dependencies to include `lifecycle-viewmodel-navigation3` and move it away from platform-specific host modules.
- Update architectural documentation (`AGENTS.md`, `GEMINI.md`, and decision logs) to reflect the adoption of centralized navigation and ViewModel scoping patterns.
- Update Navigation 3 to `1.1.0-beta01`, JetBrains Lifecycle to `2.11.0-alpha02`, and Compose Multiplatform to `1.11.0-beta01`.
- Integrate `ViewModelStoreNavEntryDecorator` and `SaveableStateHolderNavEntryDecorator` into `NavDisplay` for both Android and Desktop shells.
- Enable automatic ViewModel scoping where ViewModels obtained via `koinViewModel()` inside `entry<T>` blocks are now tied to the backstack entry's lifetime and cleared on pop.
- Add `jetbrains.lifecycle.viewmodel.navigation3` dependency to support entry-level `ViewModelStore` management.
- Update `AGENTS.md`, `GEMINI.md`, and `copilot-instructions.md` to reflect the transition from Activity/Window-scoped ViewModels to entry-scoped lifecycles.
- Introduce `navigation3-api-alignment-2026-03.md` to document the audit of Navigation 3 Scene architecture and Material 3 Adaptive integration.
- Update `kmp-status.md` and existing decision docs to reflect the new dependency baseline and predictive back handling via `NavigationBackHandler`.
