+- **Architecture**: KMP project (Android, Desktop, iOS). Business logic in `commonMain`; platform shells (`androidApp/`, `desktopApp/`) wire DI and host UI. See `AGENTS.md` and `.skills/kmp-architecture/`.
 - **Flavors**: `fdroid` (OSS) / `google` (Maps + DataDog). Only one installable at a time (different signing keys).
 - **Verify before push**: Run `./gradlew spotlessApply detekt assembleDebug test allTests`, then confirm CI with `gh pr checks <PR>`.
 - **Strings**: `stringResource(Res.string.key)` — run `python3 scripts/sort-strings.py` after adding strings.

 # CI Workflow Rules
 
-- Prefer explicit Gradle task paths (`app:lintFdroidDebug`) over shorthand (`lintDebug`).
+- Prefer explicit Gradle task paths (`androidApp:lintFdroidDebug`) over shorthand (`lintDebug`).
 - CI uses `.github/ci-gradle.properties` — don't assume local `gradle.properties` values.
 - CI passes `-Pci=true` to enable full processor usage via `maxParallelForks`.
 - Use `fetch-depth: 0` only where needed (spotless ratcheting, version code). Use `fetch-depth: 1` otherwise.
