+
+- Added dependency:
+  - `flutter_local_notifications`
+- Added concrete scheduler:
+  - `lib/features/reminders/scheduling/reminder_scheduler_local_notifications.dart`
+  - `LocalNotificationsReminderScheduler`
+  - reconciles local reminders into platform notification schedule
+  - supports recurring cadence mapping:
+    - daily -> `DateTimeComponents.time`
+    - weekly -> `DateTimeComponents.dayOfWeekAndTime`
+    - monthly -> `DateTimeComponents.dayOfMonthAndTime`
+  - web/linux gracefully no-op (scheduling fallback)
+- Provider wiring now defaults to local notifications scheduler:
+  - `lib/features/reminders/scheduling/reminder_scheduler_provider.dart`
+  - gated by `ENABLE_LOCAL_NOTIFICATIONS`
+- Added config flag:
+  - `lib/core/config/app_config.dart` -> `enableLocalNotifications`
