+<objective>
+Verify all Phase 4 notification work is complete, tests pass, and code is clean before marking the phase done.
+
+Purpose: Quality gate ensuring NOTF-01 and NOTF-02 are fully implemented before phase completion.
+Output: Verification confirmation with test counts and analysis results.

+    1. Run `dart analyze --fatal-infos` — must produce zero issues.
+    2. Run `flutter test` — must produce zero failures. Record total test count.
+    3. Verify NOTF-01 requirements by checking file existence and content:
+       - `lib/core/notifications/notification_service.dart` exists with `scheduleDailyNotification`, `requestPermission`, `cancelAll`
+       - `lib/features/home/data/daily_plan_dao.dart` has `getOverdueAndTodayTaskCount` and `getOverdueTaskCount`
+       - `android/app/src/main/AndroidManifest.xml` has `POST_NOTIFICATIONS`, `RECEIVE_BOOT_COMPLETED`, `ScheduledNotificationBootReceiver` with `exported="true"`
+       - `android/app/build.gradle.kts` has `isCoreLibraryDesugaringEnabled = true` and `compileSdk = 35`
+       - `lib/main.dart` has timezone initialization and `NotificationService().initialize()`
+    4. Verify NOTF-02 requirements by checking:
+       - `lib/core/notifications/notification_settings_notifier.dart` exists with `setEnabled`, `setTime`
+       - `lib/features/settings/presentation/settings_screen.dart` has `SwitchListTile` and `AnimatedSize` for notification section
+       - `lib/l10n/app_de.arb` has notification-related keys (`settingsSectionNotifications`, `notificationsEnabledLabel`, etc.)
+    5. Verify notification tap navigation:
+       - `lib/core/notifications/notification_service.dart` `_onTap` references `router.go('/')`
+    6. If any issues found, fix them. If all checks pass, record results.
