 ## Checklist
 
-- [ ] Code follows the project's style (ktlint passes)
-- [ ] No new compiler warnings introduced
-- [ ] If adding a new screen, checked that existing screens don't already cover the functionality (see `NavigationKeys.kt`/`ls ui/`)
-- [ ] Routes all navigation through `NavigationController.navigateTo()` — no raw `backStack.add()` from UI callbacks
-- [ ] Uses `HermesScaffold` instead of raw `Scaffold` for new/rewritten screens
-- [ ] Room schema directory updated if entities changed
-- [ ] Tested the change on a real device or CI APK
-- [ ] CI is green (all checks pass: ktlint, Android Lint, unit tests, build)
