+# Phase 2: Rooms and Tasks - Context
+
+**Gathered:** 2026-03-15
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Users can create and manage rooms and tasks, mark tasks done, and trust the app to schedule the next occurrence automatically. Delivers: room CRUD with icons and reorder, task CRUD with frequency intervals and effort levels, task completion with auto-scheduling, bundled German-language task templates for 14 room types, overdue highlighting, and room cards with cleanliness indicators.
+
+Requirements: ROOM-01, ROOM-02, ROOM-03, ROOM-04, ROOM-05, TASK-01, TASK-02, TASK-03, TASK-04, TASK-05, TASK-06, TASK-07, TASK-08, TMPL-01, TMPL-02
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Room cards & layout
+- **2-column grid** layout on the Rooms screen — compact cards, shows more rooms at once
+- Each card shows: **room icon, room name, count of due/overdue tasks, thin cleanliness progress bar**
+- No next-task preview or total task count on cards — keep them clean
+- **Cleanliness indicator**: thin horizontal progress bar at bottom of card, fill color shifts green→yellow→red based on ratio of on-time to overdue tasks
+- **Icon picker**: curated grid of ~20-30 hand-picked household Material Icons in a bottom sheet. No full icon search — focused and simple
+- Cards support drag-and-drop reorder (ROOM-04)
+- Delete room with confirmation dialog that warns about cascade deletion of all tasks (ROOM-03)
+
+### Task completion & overdue
+- **Leading checkbox** on each task row to mark done — tap to toggle. No swipe gesture.
+- Tapping the task row (not the checkbox) opens task detail/edit
+- **Overdue visual**: due date text turns warm red/coral color. Rest of row stays normal — subtle but clear
+- **No undo** on completion — immediate and final. Records timestamp, auto-calculates next due date
+- **Task row info**: task name, relative due date (e.g. "Heute", "in 3 Tagen", "Überfällig"), and frequency label (e.g. "Wöchentlich", "Alle 3 Tage"). No effort indicator or description preview on list view
+- Tasks within a room sorted by due date (default sort order, TASK-06)
+
+### Template selection flow
+- **Post-creation prompt**: user creates a room first (name + icon), then gets prompted "Aufgaben aus Vorlagen hinzufügen?" with template selection
+- **Room type is optional** — used only to determine which templates to suggest. Not stored as a permanent field. If no matching room type is detected, no template prompt appears
+- **All templates unchecked** by default — user explicitly checks what they want. No pre-selection
+- Users can create fully custom rooms (name + icon only) with no template prompt if no room type matches
+- Templates cover all 14 room types from TMPL-02: Küche, Badezimmer, Schlafzimmer, Wohnzimmer, Flur, Büro, Garage, Balkon, Waschküche, Keller, Kinderzimmer, Gästezimmer, Esszimmer, Garten/Außenbereich
+- Templates are bundled in the app as static data (German language)
+
+### Scheduling & recurrence
+- **Two interval categories** with different behavior:
+  - **Day-count intervals** (daily, every N days, weekly, biweekly): add N days from due date. Pure arithmetic, no clamping.
+  - **Calendar-anchored intervals** (monthly, quarterly, every N months, yearly): anchor to original day-of-month. If the month is shorter, clamp to last day of month but remember the anchor (e.g. task set for the 31st: Jan 31 → Feb 28 → Mar 31)
+- **Next due calculated from original due date**, not completion date — keeps rhythm stable even when completed late
+- **Catch-up on very late completion**: if calculated next due is in the past, keep adding intervals until next due is today or in the future. No stacking of missed occurrences
+- **Custom intervals**: user picks a number + unit (Tage/Wochen/Monate). E.g. "Alle 10 Tage" or "Alle 3 Monate"
+- **Preset intervals** from TASK-04: daily, every 2 days, every 3 days, weekly, biweekly, monthly, every 2 months, quarterly, every 6 months, yearly, custom
+- All due dates stored as date-only (calendar day) — established in Phase 1 pre-decision
+
+### Claude's Discretion
+- Room creation form layout (full screen vs bottom sheet vs dialog)
+- Task creation/edit form layout and field ordering
+- Exact Material Icons chosen for the curated icon picker set
+- Drag-and-drop reorder implementation approach (ReorderableListView vs custom)
+- Delete confirmation dialog design
+- Animation on task completion (checkbox fill, row transition)
+- Template data structure and storage format (Dart constants vs JSON asset)
+- Exact color values for overdue red/coral (within the sage & stone palette)
+- Empty state design for rooms with no tasks (following Phase 1 playful tone)
+
+</decisions>
+
+<specifics>
+## Specific Ideas
+
+- Room type detection for templates should be lightweight — match room name against known types, don't force a classification step
+- The template prompt after room creation should feel like a helpful suggestion, not a required step — easy to dismiss
+- Overdue text color should be warm (coral/terracotta) not harsh alarm-red — fits the calm sage & stone palette
+- Relative due date labels in German: "Heute", "Morgen", "in X Tagen", "Überfällig seit X Tagen"
+- The cleanliness bar should be subtle — thin, at the bottom edge of the card, not a dominant visual element
+- Checkbox interaction should feel instant — no loading spinners, optimistic UI
+
+</specifics>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `AppDatabase` (`lib/core/database/database.dart`): Drift database with schema v1, currently no tables — Phase 2 adds Room, Task, and TaskCompletion tables
+- `appDatabaseProvider` (`lib/core/providers/database_provider.dart`): Riverpod provider with `keepAlive: true` and `ref.onDispose(db.close)` — all DAOs will reference this
+- `ThemeNotifier` pattern (`lib/core/theme/theme_provider.dart`): AsyncNotifier with SharedPreferences persistence — template for room/task notifiers
+- `SettingsScreen` (`lib/features/settings/presentation/settings_screen.dart`): ConsumerWidget with `ref.watch` + `ref.read(...notifier)` pattern — template for reactive screens
+- `RoomsScreen` placeholder (`lib/features/rooms/presentation/rooms_screen.dart`): Ready to replace with actual room grid
+- `app_de.arb` (`lib/l10n/app_de.arb`): Localization file with 18 existing keys — Phase 2 adds room/task/frequency/effort strings
+
+### Established Patterns
+- **Riverpod 3 code generation**: `@riverpod` annotation + `.g.dart` files via build_runner. Functional providers for reads, class-based AsyncNotifier for mutations
+- **Clean architecture**: `features/X/data/domain/presentation` layer structure. Presentation never imports directly from data layer
+- **GoRouter StatefulShellRoute**: `/rooms` branch exists, ready for nested routes (`/rooms/:roomId`, `/rooms/:roomId/tasks/new`)
+- **Material 3 theming**: `ColorScheme.fromSeed` with sage green seed (0xFF7A9A6D), warm stone surfaces. All color via `Theme.of(context).colorScheme`
+- **Localization**: ARB-based, German-only, strongly typed `AppLocalizations.of(context).keyName`
+- **Database testing**: `NativeDatabase.memory()` for in-memory tests, `setUp/tearDown` pattern
+- **Widget testing**: `ProviderScope` + `MaterialApp.router` with German locale
+
+### Integration Points
+- Phase 2 replaces the `RoomsScreen` placeholder with the actual room grid
+- Room cards link to room detail screens via GoRouter nested routes under `/rooms`
+- Task completion data feeds Phase 3's daily plan view (overdue/today/upcoming grouping)
+- Cleanliness indicator logic established here is reused by Phase 3 room cards on the Home screen
+- Phase 4 notifications query task due dates established in this phase's schema

+<objective>
+Build the data and provider layers for the daily plan feature: a Drift DAO with cross-room join query, a DailyPlanState model with overdue/today/tomorrow categorization, a Riverpod provider combining task and completion streams, localization keys, and unit tests.
+
+Purpose: Provides the reactive data foundation that the daily plan UI (Plan 02) will consume. Separated from UI to keep each plan at ~50% context.
+Output: DailyPlanDao with join query, DailyPlanState model, dailyPlanProvider, localization keys, and passing unit tests.

+  </behavior>
+  <action>
+    1. Create `lib/features/home/domain/daily_plan_models.dart` with:
+       - `TaskWithRoom` class: `final Task task`, `final String roomName`, `final int roomId`, const constructor
+       - `DailyPlanState` class: `final List<TaskWithRoom> overdueTasks`, `final List<TaskWithRoom> todayTasks`, `final List<TaskWithRoom> tomorrowTasks`, `final int completedTodayCount`, `final int totalTodayCount`, const constructor
+
+    2. Create `lib/features/home/data/daily_plan_dao.dart` with:
+       - `@DriftAccessor(tables: [Tasks, Rooms, TaskCompletions])`
+       - `class DailyPlanDao extends DatabaseAccessor<AppDatabase> with _$DailyPlanDaoMixin`
+       - `Stream<List<TaskWithRoom>> watchAllTasksWithRoomName()`: innerJoin tasks with rooms on rooms.id.equalsExp(tasks.roomId), orderBy nextDueDate asc, map rows using readTable(tasks) and readTable(rooms)
+       - `Stream<int> watchCompletionsToday({DateTime? today})`: count TaskCompletions where completedAt >= startOfDay AND completedAt < endOfDay. Use customSelect with SQL COUNT(*) and readsFrom: {taskCompletions} for proper stream invalidation
+
+    3. Register DailyPlanDao in `lib/core/database/database.dart`:
+       - Add import for daily_plan_dao.dart
+       - Add `DailyPlanDao` to `@DriftDatabase(daos: [...])` list
+       - Run `dart run build_runner build --delete-conflicting-outputs` to regenerate database.g.dart and daily_plan_dao.g.dart
+
+    4. Create `test/features/home/data/daily_plan_dao_test.dart`:
+       - Follow existing tasks_dao_test.dart pattern: `AppDatabase(NativeDatabase.memory())`, setUp/tearDown
+       - Create 2 rooms and insert tasks with different due dates across them
+       - Test all behaviors listed above
+       - Use stream.first for single-emission testing (same pattern as existing tests)
+
+    IMPORTANT: The customSelect approach for watchCompletionsToday must use `readsFrom: {taskCompletions}` so Drift knows which table to watch for stream invalidation. Without this, the stream won't re-fire on new completions.

+    lib/features/home/presentation/daily_plan_providers.dart,
+    lib/l10n/app_de.arb
+  </files>
+  <action>
+    1. Create `lib/features/home/presentation/daily_plan_providers.dart` with:
+       - Import daily_plan_models.dart, database_provider.dart
+       - Define `dailyPlanProvider` as a manual `StreamProvider.autoDispose<DailyPlanState>` (NOT using @riverpod, same pattern as tasksInRoomProvider because drift Task type causes riverpod_generator issues)
+       - Inside provider: `ref.watch(appDatabaseProvider)` to get db
+       - Watch `db.dailyPlanDao.watchAllTasksWithRoomName()` stream
+       - Use `.asyncMap()` on the task stream to:
+         a. Get completions today count via `db.dailyPlanDao.watchCompletionsToday().first`
+         b. Compute `today = DateTime(now.year, now.month, now.day)`, `tomorrow = today + 1 day`, `dayAfterTomorrow = tomorrow + 1 day`
+         c. Partition tasks into: overdue (dueDate < today), todayList (today <= dueDate < tomorrow), tomorrowList (tomorrow <= dueDate < dayAfterTomorrow)
+         d. Compute totalTodayCount = overdue.length + todayList.length + completedTodayCount
+         e. Return DailyPlanState with all fields
+
+    CRITICAL for progress accuracy: totalTodayCount includes completedTodayCount so the denominator stays stable as tasks are completed. Without this, completing a task would shrink the total (since the task moves to a future due date), making progress appear to go backward.
+
+    2. Add localization keys to `lib/l10n/app_de.arb` (add these AFTER existing keys, before the closing brace):
+       ```json
+       "dailyPlanProgress": "{completed} von {total} erledigt",
+       "@dailyPlanProgress": {
+         "placeholders": {
+           "completed": { "type": "int" },
+           "total": { "type": "int" }
+         }
+       },

+       "dailyPlanSectionToday": "Heute",
+       "dailyPlanSectionUpcoming": "Demn\u00e4chst",
+       "dailyPlanUpcomingCount": "Demn\u00e4chst ({count})",
+       "@dailyPlanUpcomingCount": {
+         "placeholders": {
+           "count": { "type": "int" }
+         }
+       },
+       "dailyPlanAllClearTitle": "Alles erledigt! \ud83c\udf1f",

+       "dailyPlanNoTasks": "Noch keine Aufgaben angelegt"
+       ```
+
+    Note: Use Unicode escapes for umlauts in ARB keys (same pattern as existing keys). The "all clear" title includes a star emoji per the established playful German tone from Phase 1.
+
+    3. Run `flutter gen-l10n` (or `flutter pub get` which triggers it) to regenerate localization classes.
+
+    4. Verify `dart analyze` passes clean on all new files.

+# Phase 3 Plan 01: Daily Plan Data Layer Summary
+
+**Drift DailyPlanDao with cross-room join query, completion count stream, Riverpod provider with overdue/today/tomorrow categorization, and 10 German localization keys**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-16T11:26:02Z
+- **Completed:** 2026-03-16T11:31:13Z
+- **Tasks:** 2
+- **Files modified:** 10
+
+## Accomplishments
+- DailyPlanDao with `watchAllTasksWithRoomName()` returning tasks joined with room names, sorted by due date
+- `watchCompletionsToday()` using customSelect with readsFrom for proper reactive stream invalidation
+- `dailyPlanProvider` categorizing tasks into overdue/today/tomorrow with stable progress denominator
+- TaskWithRoom and DailyPlanState model classes providing the data contract for Plan 02's UI
+- 7 unit tests covering all DAO behaviors (empty state, join correctness, sort order, cross-room pairing, completion counts, date boundaries)
+- 10 new German localization keys for daily plan sections, progress text, empty states
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1 RED: Failing tests for DailyPlanDao** - `74b3bd5` (test)
+2. **Task 1 GREEN: DailyPlanDao implementation** - `ad70eb7` (feat)
+3. **Task 2: Daily plan provider and localization keys** - `1c09a43` (feat)
+
+_TDD task had RED and GREEN commits. No REFACTOR needed -- code was clean._
+
+## Files Created/Modified
+- `lib/features/home/data/daily_plan_dao.dart` - DailyPlanDao with cross-room join query and completion count stream
+- `lib/features/home/data/daily_plan_dao.g.dart` - Generated Drift mixin for DailyPlanDao
+- `lib/features/home/domain/daily_plan_models.dart` - TaskWithRoom and DailyPlanState data classes
+- `lib/features/home/presentation/daily_plan_providers.dart` - dailyPlanProvider with date categorization and progress tracking
+- `test/features/home/data/daily_plan_dao_test.dart` - 7 unit tests for DailyPlanDao behaviors
+- `lib/core/database/database.dart` - Added DailyPlanDao import and registration
+- `lib/core/database/database.g.dart` - Regenerated with DailyPlanDao accessor
+- `lib/l10n/app_de.arb` - 10 new daily plan localization keys
+- `lib/l10n/app_localizations.dart` - Regenerated with new key accessors
+- `lib/l10n/app_localizations_de.dart` - Regenerated with German translations
+
+## Decisions Made
+- Used `innerJoin` (not `leftOuterJoin`) since every task always belongs to a room -- no orphaned tasks possible with foreign key constraint
+- `watchCompletionsToday` uses `customSelect` with raw SQL COUNT(*) and `readsFrom: {taskCompletions}` to ensure Drift knows which table to watch for stream invalidation. The selectOnly approach would also work but customSelect is more explicit about the reactive dependency.
+- `dailyPlanProvider` defined as manual `StreamProvider.autoDispose` (same pattern as `tasksInRoomProvider`) because riverpod_generator has `InvalidTypeException` with drift's generated `Task` type
+- Progress denominator formula: `overdue.length + todayList.length + completedTodayCount` keeps the total stable as tasks are completed and move to future due dates
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Data layer complete: DailyPlanDao, models, and provider ready for Plan 02 UI consumption
+- Plan 02 can directly `ref.watch(dailyPlanProvider)` to get categorized task data
+- All localization keys for daily plan UI are available via AppLocalizations
+- 66/66 tests passing with no regressions
+
+## Self-Check: PASSED
+
+All 5 created files verified present on disk. All 3 commit hashes verified in git log.

+<objective>
+Build the daily plan UI: replace the HomeScreen placeholder with the full daily plan screen featuring a progress card, overdue/today/tomorrow sections, animated task completion, and "all clear" empty state.
+
+Purpose: This is the app's primary screen -- the first thing users see. It transforms the placeholder Home tab into the core daily workflow: see what's due, check it off, feel progress.
+Output: Complete HomeScreen rewrite, DailyPlanTaskRow widget, ProgressCard widget, and widget tests.

+       - `class DailyPlanTaskRow extends StatelessWidget` (NOT ConsumerWidget -- no ref needed; completion callback passed in)
+       - Constructor params: `required TaskWithRoom taskWithRoom`, `required bool showCheckbox`, `VoidCallback? onCompleted`
+       - Build a `ListTile` with:
+         - `leading`: If showCheckbox, a `Checkbox(value: false, onChanged: (_) => onCompleted?.call())`. If not showCheckbox, null (tomorrow tasks are read-only)
+         - `title`: `Text(task.name)` with titleMedium, maxLines 1, ellipsis overflow
+         - `subtitle`: A `Row` containing:
+           a. Room name tag: `GestureDetector` wrapping a `Container` with `secondaryContainer` background, rounded corners (4px), containing `Text(roomName)` in `labelSmall` with `onSecondaryContainer` color. `onTap: () => context.go('/rooms/${taskWithRoom.roomId}')`
+           b. `SizedBox(width: 8)`
+           c. Relative date text via `formatRelativeDate(task.nextDueDate, DateTime.now())`. Color: `_overdueColor` (0xFFE07A5F) if overdue, `onSurfaceVariant` otherwise. Overdue check: dueDate (date-only) < today (date-only)
+         - NO `onTap` -- per user decision, daily plan task rows have no row-tap navigation. Only checkbox and room tag are interactive
+         - NO `onLongPress` -- no edit/delete from daily plan
+
+    2. Create `lib/features/home/presentation/progress_card.dart`:
+       - `class ProgressCard extends StatelessWidget`
+       - Constructor: `required int completed`, `required int total`
+       - Build a `Card` with `margin: EdgeInsets.all(16)`:

+         - `SizedBox(height: 12)`

+  </files>
+  <action>
+    1. COMPLETE REWRITE of `lib/features/home/presentation/home_screen.dart`:
+       - Change from `StatelessWidget` to `ConsumerStatefulWidget` (needs ref for providers AND state for AnimatedList keys)
+       - `ref.watch(dailyPlanProvider)` in build method
+       - Use `AsyncValue.when(loading: ..., error: ..., data: ...)` pattern:
+         - `loading`: Center(child: CircularProgressIndicator())
+         - `error`: Center(child: Text(error.toString()))
+         - `data`: Build the daily plan UI
+
+       DAILY PLAN UI STRUCTURE (data case):
+
+       a. **"No tasks at all" state**: If totalTodayCount == 0 AND tomorrowTasks.isEmpty AND completedTodayCount == 0, show the existing empty state pattern (homeEmptyTitle / homeEmptyMessage / homeEmptyAction button navigating to /rooms). This covers the case where the user has not created any rooms/tasks yet. Use `dailyPlanNoTasks` localization key for this.
+
+       b. **"All clear" state** (PLAN-06): If overdueTasks.isEmpty AND todayTasks.isEmpty AND completedTodayCount > 0, show celebration empty state: `Icons.celebration_outlined` (size 80, onSurface alpha 0.4), `dailyPlanAllClearTitle`, `dailyPlanAllClearMessage`. This means there WERE tasks today but they're all done.
+
+       c. **"Also all clear but nothing was ever due today"**: If overdueTasks.isEmpty AND todayTasks.isEmpty AND completedTodayCount == 0 AND tomorrowTasks.isNotEmpty, show same celebration empty state but with the progress card showing 0/0 and then the tomorrow section. (Edge case: nothing today, but stuff tomorrow.)
+
+       d. **Normal state** (tasks exist): `ListView` with:
+         1. `ProgressCard(completed: completedTodayCount, total: totalTodayCount)` -- always first
+         2. If overdueTasks.isNotEmpty: Section header "Uberfaellig" (titleMedium, warm coral color 0xFFE07A5F) with `Padding(horizontal: 16, vertical: 8)`, followed by `DailyPlanTaskRow` for each overdue task with `showCheckbox: true`
+         3. Section header "Heute" (titleMedium, primary color) with same padding, followed by `DailyPlanTaskRow` for each today task with `showCheckbox: true`
+         4. If tomorrowTasks.isNotEmpty: `ExpansionTile` with `initiallyExpanded: false`, title: `dailyPlanUpcomingCount(count)` in titleMedium. Children: `DailyPlanTaskRow` for each tomorrow task with `showCheckbox: false`
+
+       COMPLETION ANIMATION (PLAN-04):
+       - For the simplicity-first approach (avoiding AnimatedList desync pitfalls from research): When checkbox is tapped, call `ref.read(taskActionsProvider.notifier).completeTask(taskId)`. The Drift stream will naturally re-emit without the completed task (its nextDueDate moves to the future). This provides a seamless removal.
+       - To add visual feedback: Wrap each DailyPlanTaskRow in the overdue and today sections with an `AnimatedSwitcher` (or use `AnimatedList` if confident). The simplest approach: maintain a local `Set<int> _completingTaskIds` in state. When checkbox tapped, add taskId to set, triggering a rebuild that wraps the row in `SizeTransition` animating to zero height over 300ms. After animation, the stream re-emission removes it permanently.
+       - Alternative simpler approach: Use a plain ListView. On checkbox tap, fire completeTask(). The stream re-emission rebuilds the list without the task. No explicit animation, but the progress counter updates immediately giving visual feedback. This is acceptable for v1.
+       - RECOMMENDED: Use `AnimatedList` with `GlobalKey<AnimatedListState>` for overdue+today section. On completion, call `removeItem()` with `SizeTransition + SlideTransition` (slide right, 300ms, easeInOut). Fire `completeTask()` simultaneously. When the stream re-emits, compare with local list and reconcile. See research Pattern 3 for exact code. BUT if this proves complex during implementation, fall back to the simpler "let stream handle it" approach.
+
+    2. Create `test/features/home/presentation/home_screen_test.dart`:
+       - Use provider override pattern (same as app_shell_test.dart):
+         - Override `dailyPlanProvider` with a `StreamProvider` returning test data
+         - Override `appDatabaseProvider` if needed
+       - Test cases:
+         a. Empty state: When no tasks exist, shows homeEmptyTitle text and action button
+         b. All clear state: When overdue=[], today=[], completedTodayCount > 0, shows "Alles erledigt!" text
+         c. Normal state: When tasks exist, shows progress card with correct counts
+         d. Overdue section: When overdue tasks exist, shows "Uberfaellig" header
+         e. Tomorrow section: Shows collapsed "Demnachst" header with count
+
+    3. Run `flutter test` to confirm all tests pass (existing + new).

+# Phase 3 Plan 02: Daily Plan UI Summary
+
+**Complete daily plan HomeScreen with progress card, overdue/today/tomorrow sections, animated checkbox completion, and celebration empty state**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-03-16T11:35:00Z
+- **Completed:** 2026-03-16T11:39:17Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+- HomeScreen fully rewritten from placeholder to complete daily plan with progress card, three task sections, and animated completion
+- DailyPlanTaskRow with tappable room name tag (navigates to room), relative date (coral if overdue), optional checkbox, no row-tap
+- ProgressCard showing "X von Y erledigt" with LinearProgressIndicator
+- Animated task completion: checkbox tap triggers SizeTransition + SlideTransition animation while stream re-emission permanently removes the task
+- Three empty states: no-tasks (first-run), all-clear (celebration), all-clear-with-tomorrow
+- 6 widget tests covering all states; 72/72 tests passing with no regressions
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: DailyPlanTaskRow and ProgressCard widgets** - `4e3a3ed` (feat)
+2. **Task 2: HomeScreen rewrite with daily plan sections, animated completion, empty state, and tests** - `444213e` (feat)
+
+## Files Created/Modified
+- `lib/features/home/presentation/daily_plan_task_row.dart` - Task row for daily plan with room tag, relative date, optional checkbox
+- `lib/features/home/presentation/progress_card.dart` - Progress banner card with linear progress bar
+- `lib/features/home/presentation/home_screen.dart` - Complete rewrite: ConsumerStatefulWidget with daily plan UI
+- `test/features/home/presentation/home_screen_test.dart` - 6 widget tests for empty, all-clear, normal states
+- `test/shell/app_shell_test.dart` - Updated to override dailyPlanProvider for new HomeScreen
+
+## Decisions Made
+- Used simpler stream-driven completion with local `_completingTaskIds` Set instead of AnimatedList. The stream naturally re-emits without completed tasks (nextDueDate moves to future), and the local Set provides immediate visual feedback via SizeTransition + SlideTransition animation during the ~300ms before re-emission.
+- DailyPlanTaskRow is a plain StatelessWidget (not ConsumerWidget). It receives `TaskWithRoom`, `showCheckbox`, and `onCompleted` callback from the parent. This keeps it decoupled from Riverpod and easily testable.
+- The "no tasks" empty state now uses `dailyPlanNoTasks` ("Noch keine Aufgaben angelegt") instead of `homeEmptyTitle` ("Noch nichts zu tun!") for more specific messaging in the daily plan context.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Updated app_shell_test.dart for new HomeScreen dependency**
+- **Found during:** Task 2 (HomeScreen rewrite)
+- **Issue:** Existing app_shell_test.dart expected `homeEmptyTitle` text on home tab, but new HomeScreen watches `dailyPlanProvider` and shows different empty state text
+- **Fix:** Added `dailyPlanProvider` override to test's ProviderScope, updated assertion from "Noch nichts zu tun!" to "Noch keine Aufgaben angelegt"
+- **Files modified:** test/shell/app_shell_test.dart
+- **Verification:** Full test suite passes (72/72)
+- **Committed in:** 444213e (Task 2 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug fix)
+**Impact on plan:** Necessary fix for existing test compatibility. No scope creep.
+
+## Issues Encountered
+- "Heute" text appeared twice in overdue+today test (section header + relative date for today task). Fixed by using `findsAtLeast(1)` matcher instead of `findsOneWidget`.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Daily plan UI complete: HomeScreen shows progress, overdue, today, and tomorrow sections
+- Plan 03 (verification gate) can proceed to validate full Phase 3 integration
+- CLEAN-01 verified: room cards already display cleanliness indicator from Phase 2
+- 72/72 tests passing, dart analyze clean on production code

+# Phase 3: Daily Plan and Cleanliness - Research
+
+**Researched:** 2026-03-16
+**Domain:** Flutter daily plan screen with cross-room Drift queries, animated task completion, sectioned list UI, progress indicators
+**Confidence:** HIGH
+
+## Summary
+
+Phase 3 transforms the placeholder Home tab into the app's primary "daily plan" screen -- the first thing users see when opening HouseHoldKeaper. The screen needs three key capabilities: (1) a cross-room Drift query that watches all tasks and categorizes them by due date (overdue, today, tomorrow), (2) animated task removal on checkbox completion with the existing `TasksDao.completeTask()` logic, and (3) a progress indicator card showing "X von Y erledigt" that updates in real-time.
+
+The existing codebase provides strong foundations: `TasksDao.completeTask()` already handles completion + scheduling in a single transaction, `formatRelativeDate()` produces German date labels, `TaskRow` provides the baseline task row widget (needs adaptation), and the Riverpod stream provider pattern is well-established. The main new work is: (a) a new DAO method that joins tasks with rooms for cross-room queries, (b) a `DailyPlanTaskRow` widget variant with room name tag and no row-tap navigation, (c) `AnimatedList` for slide-out completion animation, (d) `ExpansionTile` for the collapsible "Demnachst" section, and (e) new localization strings.
+
+CLEAN-01 (cleanliness indicator on room cards) is already fully implemented in Phase 2 via `RoomWithStats.cleanlinessRatio` and the `LinearProgressIndicator` bar at the bottom of `RoomCard`. This requirement needs only verification, not new implementation.
+
+**Primary recommendation:** Add a single new DAO method `watchAllTasksWithRoomName()` that joins tasks with rooms, expose it through a manual `StreamProvider` (same pattern as `tasksInRoomProvider` due to drift type issues), derive overdue/today/tomorrow categorization in the provider layer, and build the daily plan screen as a `CustomScrollView` with `SliverAnimatedList` for animated completion.
+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+- **Daily plan screen structure**: Single scroll list with three section headers: Uberfaellig, Heute, Demnachst. Flat task list within each section -- tasks are not grouped under room sub-headers. Each task row shows room name as an inline tappable tag that navigates to that room's task list. Progress indicator at the very top as a prominent card/banner ("5 von 12 erledigt") -- first thing the user sees. Overdue section only appears when there are overdue tasks. Demnachst section is collapsed by default -- shows header with count (e.g. "Demnachst (4)"), expands on tap. PLAN-01 "grouped by room" is satisfied by room name shown on each task -- not visual sub-grouping.
+- **Task completion on daily plan**: Checkbox only -- no swipe-to-complete gesture. Consistent with Phase 2 room task list. Completed tasks animate out of the list (slide away). Progress counter updates immediately. No navigation from tapping task rows -- the daily plan is a focused "get things done" screen. Only the checkbox and the room name tag are interactive. Completion behavior identical to Phase 2: immediate, no undo, records timestamp, auto-calculates next due date.
+- **Upcoming tasks scope**: Tomorrow only -- Demnachst shows tasks due the next calendar day. Read-only preview -- no checkboxes, tasks cannot be completed ahead of schedule from the daily plan. Collapsed by default to keep focus on today's actionable tasks.
+
+### Claude's Discretion
+- "All clear" empty state design (follow Phase 1's playful, emoji-friendly German tone with the established visual pattern: Material icon + message + optional action)
+- Task row adaptation for daily plan context (may differ from TaskRow in room view since no row-tap navigation and room name tag is added)
+- Exact animation for task completion (slide direction, duration, easing)
+- Progress card/banner visual design (linear progress bar, circular, or text-only)
+- Section header styling and the collapsed/expanded toggle for Demnachst
+- How overdue tasks are sorted within the flat list (most overdue first, or by room, or alphabetical)
+

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| PLAN-01 | User sees all tasks due today grouped by room on the daily plan screen | New DAO join query `watchAllTasksWithRoomName()`, flat list with room name tag on each row satisfies "grouped by room" per CONTEXT.md |
+| PLAN-02 | Overdue tasks appear in a separate highlighted section at the top | Provider-layer date categorization splits tasks into overdue/today/tomorrow sections; overdue section conditionally rendered |
+| PLAN-03 | User can preview upcoming tasks (tomorrow) | Demnachst section with `ExpansionTile` collapsed by default, read-only rows (no checkbox) |
+| PLAN-04 | User can checkbox to mark tasks done from daily plan | Reuse existing `taskActionsProvider.completeTask()`, `AnimatedList.removeItem()` for slide-out animation |
+| PLAN-05 | Progress indicator showing completed vs total tasks today | Computed from stream data: `completedToday` count from `TaskCompletions` + `totalToday` from due tasks. Progress card at top of screen |
+| PLAN-06 | "All clear" empty state when no tasks are due | Established empty state pattern (Material icon + message + optional action) in German |
+| CLEAN-01 | Each room card displays cleanliness indicator | Already implemented in Phase 2 via `RoomWithStats.cleanlinessRatio` and `RoomCard` -- verification only |

+## Standard Stack
+
+### Core (already in project)
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| drift | 2.31.0 | Type-safe SQLite ORM with join queries | Already established; provides `leftOuterJoin`, `.watch()` streams for cross-room task queries |
+| flutter_riverpod | 3.3.1 | State management | Already established; `StreamProvider` pattern for reactive daily plan data |
+| riverpod_annotation | 4.0.2 | Provider code generation | `@riverpod` for generated providers |
+| go_router | 17.1.0 | Declarative routing | Room name tag navigation uses `context.go('/rooms/$roomId')` |
+| flutter (SDK) | 3.41.1 | Framework | Provides `AnimatedList`, `ExpansionTile`, `LinearProgressIndicator` |
+
+### New Dependencies
+None. Phase 3 uses only Flutter built-in widgets and existing project dependencies.
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| `AnimatedList` with manual state sync | Simple `ListView` with `AnimatedSwitcher` | `AnimatedList` provides proper slide-out with `removeItem()`. `AnimatedSwitcher` only fades, no size collapse. Use `AnimatedList`. |
+| `ExpansionTile` for Demnachst | Custom `AnimatedContainer` | `ExpansionTile` is Material 3 native, handles expand/collapse animation, arrow icon, and state automatically. No reason to hand-roll. |
+| `LinearProgressIndicator` in card | `CircularProgressIndicator` or custom radial | Linear is simpler, more glanceable for "X von Y" context, and matches the progress bar pattern already on room cards. Use linear. |
+| Drift join query | In-memory join via multiple stream providers | Drift join runs in SQLite, more efficient for large task counts, and produces a single reactive stream. In-memory join requires watching two streams and combining, more complex. |

+
+### Pattern 1: Drift Join Query for Tasks with Room Name
+**What:** A DAO method that joins the tasks table with rooms to produce task objects paired with their room name, watched as a reactive stream.
+**When to use:** Daily plan needs all tasks across all rooms with room name for display.
+**Example:**
+```dart
+// Source: drift.simonbinder.eu/dart_api/select/ (join documentation)
+
+/// A task paired with its room name for daily plan display.
+class TaskWithRoom {
+  final Task task;
+  final String roomName;
+  final int roomId;
+
+  const TaskWithRoom({
+    required this.task,
+    required this.roomName,
+    required this.roomId,
+  });
+}
+
+@DriftAccessor(tables: [Tasks, Rooms, TaskCompletions])
+class DailyPlanDao extends DatabaseAccessor<AppDatabase>
+    with _$DailyPlanDaoMixin {
+  DailyPlanDao(super.attachedDatabase);
+
+  /// Watch all tasks joined with room name, sorted by nextDueDate ascending.
+  Stream<List<TaskWithRoom>> watchAllTasksWithRoomName() {
+    final query = select(tasks).join([
+      innerJoin(rooms, rooms.id.equalsExp(tasks.roomId)),
+    ]);
+    query.orderBy([OrderingTerm.asc(tasks.nextDueDate)]);
+
+    return query.watch().map((rows) {
+      return rows.map((row) {
+        final task = row.readTable(tasks);
+        final room = row.readTable(rooms);
+        return TaskWithRoom(
+          task: task,
+          roomName: room.name,
+          roomId: room.id,
+        );
+      }).toList();
+    });
+  }
+
+  /// Count completions recorded today (for progress tracking).
+  /// Counts tasks completed today regardless of their current due date.
+  Stream<int> watchCompletionsToday({DateTime? now}) {
+    final today = now ?? DateTime.now();
+    final startOfDay = DateTime(today.year, today.month, today.day);
+    final endOfDay = startOfDay.add(const Duration(days: 1));
+
+    final query = selectOnly(taskCompletions)
+      ..addColumns([taskCompletions.id.count()])
+      ..where(taskCompletions.completedAt.isBiggerOrEqualValue(startOfDay) &
+          taskCompletions.completedAt.isSmallerThanValue(endOfDay));
+
+    return query.watchSingle().map((row) {
+      return row.read(taskCompletions.id.count()) ?? 0;
+    });
+  }
+}
+```
+
+### Pattern 2: Provider-Layer Date Categorization
+**What:** A Riverpod provider that watches the raw task stream and categorizes tasks into overdue, today, and tomorrow sections. Also computes progress stats.
+**When to use:** Transforming flat task data into the three-section daily plan structure.
+**Example:**
+```dart
+/// Daily plan data categorized into sections.
+class DailyPlanState {
+  final List<TaskWithRoom> overdueTasks;
+  final List<TaskWithRoom> todayTasks;
+  final List<TaskWithRoom> tomorrowTasks;
+  final int completedTodayCount;
+  final int totalTodayCount; // overdue + today (actionable tasks)
+
+  const DailyPlanState({
+    required this.overdueTasks,
+    required this.todayTasks,
+    required this.tomorrowTasks,
+    required this.completedTodayCount,
+    required this.totalTodayCount,
+  });
+}
+
+// Manual StreamProvider (same pattern as tasksInRoomProvider)
+// due to drift Task type issue with riverpod_generator
+final dailyPlanProvider =
+    StreamProvider.autoDispose<DailyPlanState>((ref) {
+  final db = ref.watch(appDatabaseProvider);
+  final taskStream = db.dailyPlanDao.watchAllTasksWithRoomName();
+  final completionStream = db.dailyPlanDao.watchCompletionsToday();
+
+  // Combine both streams using Dart's asyncMap pattern
+  return taskStream.asyncMap((allTasks) async {
+    // Get today's completion count (latest value)
+    final completedToday = await db.dailyPlanDao
+        .watchCompletionsToday().first;
+
+    final now = DateTime.now();
+    final today = DateTime(now.year, now.month, now.day);
+    final tomorrow = today.add(const Duration(days: 1));
+    final dayAfterTomorrow = tomorrow.add(const Duration(days: 1));
+
+    final overdue = <TaskWithRoom>[];
+    final todayList = <TaskWithRoom>[];
+    final tomorrowList = <TaskWithRoom>[];
+
+    for (final tw in allTasks) {
+      final dueDate = DateTime(
+        tw.task.nextDueDate.year,
+        tw.task.nextDueDate.month,
+        tw.task.nextDueDate.day,
+      );
+      if (dueDate.isBefore(today)) {
+        overdue.add(tw);
+      } else if (dueDate.isBefore(tomorrow)) {
+        todayList.add(tw);
+      } else if (dueDate.isBefore(dayAfterTomorrow)) {
+        tomorrowList.add(tw);
+      }
+    }
+
+    return DailyPlanState(
+      overdueTasks: overdue, // already sorted by dueDate from query
+      todayTasks: todayList,
+      tomorrowTasks: tomorrowList,
+      completedTodayCount: completedToday,
+      totalTodayCount: overdue.length + todayList.length + completedToday,
+    );
+  });
+});
+```
+
+### Pattern 3: AnimatedList for Task Completion Slide-Out
+**What:** Use `AnimatedList` with `GlobalKey<AnimatedListState>` to animate task removal when checkbox is tapped. The removed item slides horizontally and collapses vertically.
+**When to use:** Overdue and Today sections where tasks have checkboxes.
+**Example:**
+```dart
+// Slide-out animation for completed tasks
+void _onTaskCompleted(int index, TaskWithRoom taskWithRoom) {
+  // 1. Trigger database completion (fire-and-forget)
+  ref.read(taskActionsProvider.notifier).completeTask(taskWithRoom.task.id);
+
+  // 2. Animate the item out of the list
+  _listKey.currentState?.removeItem(
+    index,
+    (context, animation) {
+      // Combine slide + size collapse for smooth exit
+      return SizeTransition(
+        sizeFactor: animation,
+        child: SlideTransition(
+          position: Tween<Offset>(
+            begin: const Offset(1.0, 0.0), // slide right
+            end: Offset.zero,
+          ).animate(CurvedAnimation(
+            parent: animation,
+            curve: Curves.easeInOut,
+          )),
+          child: DailyPlanTaskRow(
+            taskWithRoom: taskWithRoom,
+            showCheckbox: true,
+            onCompleted: () {},
+          ),
+        ),
+      );
+    },
+    duration: const Duration(milliseconds: 300),
+  );
+}
+```
+
+### Pattern 4: ExpansionTile for Collapsible Demnachst Section
+**What:** Use Flutter's built-in `ExpansionTile` for the "Demnachst (N)" collapsible section. Starts collapsed per user decision.
+**When to use:** Tomorrow tasks section that is read-only and collapsed by default.
+**Example:**
+```dart
+ExpansionTile(
+  initiallyExpanded: false,
+  title: Text(
+    '${l10n.dailyPlanUpcoming} (${tomorrowTasks.length})',
+    style: theme.textTheme.titleMedium,
+  ),
+  children: tomorrowTasks.map((tw) => DailyPlanTaskRow(
+    taskWithRoom: tw,
+    showCheckbox: false, // read-only, no completion from daily plan
+    onRoomTap: () => context.go('/rooms/${tw.roomId}'),
+  )).toList(),
+);
+```
+
+### Pattern 5: Progress Card with LinearProgressIndicator
+**What:** A card/banner at the top of the daily plan showing "X von Y erledigt" with a linear progress bar beneath.
+**When to use:** First widget in the daily plan scroll, shows today's completion progress.
+**Example:**
+```dart
+class ProgressCard extends StatelessWidget {
+  final int completed;
+  final int total;
+
+  const ProgressCard({
+    super.key,
+    required this.completed,
+    required this.total,
+  });
+
+  @override
+  Widget build(BuildContext context) {
+    final theme = Theme.of(context);
+    final l10n = AppLocalizations.of(context);
+    final progress = total > 0 ? completed / total : 0.0;
+
+    return Card(
+      margin: const EdgeInsets.all(16),
+      child: Padding(
+        padding: const EdgeInsets.all(16),
+        child: Column(
+          crossAxisAlignment: CrossAxisAlignment.start,
+          children: [
+            Text(
+              l10n.dailyPlanProgress(completed, total),
+              style: theme.textTheme.titleMedium?.copyWith(
+                fontWeight: FontWeight.bold,
+              ),
+            ),
+            const SizedBox(height: 12),
+            ClipRRect(
+              borderRadius: BorderRadius.circular(4),
+              child: LinearProgressIndicator(
+                value: progress,
+                minHeight: 8,
+                backgroundColor: theme.colorScheme.surfaceContainerHighest,
+                color: theme.colorScheme.primary,
+              ),
+            ),
+          ],
+        ),
+      ),
+    );
+  }
+}
+```
+
+### Anti-Patterns to Avoid
+- **Using `AnimatedList` for ALL sections (including Demnachst):** The tomorrow section is read-only -- no items are added or removed dynamically. A plain `Column` inside `ExpansionTile` is simpler and avoids unnecessary `GlobalKey` management.
+- **Rebuilding `AnimatedList` on every stream emission:** `AnimatedList` requires imperative `insertItem`/`removeItem` calls. Rebuilding the widget discards animation state. The list must synchronize imperatively with stream data, OR use a simpler approach where completion removes from a local list and the stream handles the rest after animation completes.
+- **Using a single monolithic `AnimatedList` for all three sections:** Each section has different behavior (overdue: checkbox, today: checkbox, tomorrow: no checkbox, collapsible). Use separate widgets per section.
+- **Computing progress from stream-only data:** After completing a task, it moves to a future due date and disappears from "today". The completion count must come from `TaskCompletions` table (tasks completed today), not from the absence of tasks in the stream.
+- **Navigating on task row tap:** Per user decision, daily plan task rows have NO row-tap navigation. Only the checkbox and room name tag are interactive. Do NOT reuse `TaskRow` directly -- it has `onTap` navigating to edit form.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Expand/collapse section | Custom `AnimatedContainer` + boolean state | `ExpansionTile` | Material 3 native, handles animation, arrow icon, state persistence automatically |
+| Cross-room task query | Multiple stream providers + in-memory merge | Drift `join` query with `.watch()` | Single SQLite query is more efficient and produces one reactive stream |
+| Progress bar | Custom `CustomPainter` circular indicator | `LinearProgressIndicator` with `value` | Built-in Material 3 widget, themed automatically, supports determinate mode |
+| Slide-out animation | Manual `AnimationController` per row | `AnimatedList.removeItem()` with `SizeTransition` + `SlideTransition` | Framework handles list index bookkeeping and animation lifecycle |
+| Date categorization | Separate DB queries per category | Single query + in-memory partitioning | One Drift stream for all tasks, partitioned in Dart. Fewer database watchers, simpler invalidation |
+
+**Key insight:** Phase 3 is primarily a presentation-layer phase. The data layer changes are minimal (one new DAO method + registering the DAO). Most complexity is in the UI: synchronizing `AnimatedList` state with reactive stream data, and building a polished sectioned scroll view with proper animation.
+
+## Common Pitfalls
+
+### Pitfall 1: AnimatedList State Desynchronization
+**What goes wrong:** `AnimatedList` requires imperative `insertItem()`/`removeItem()` calls to stay in sync with the data. If the widget rebuilds from a new stream emission while an animation is in progress, the list state and data diverge, causing index-out-of-bounds or duplicate item errors.
+**Why it happens:** `AnimatedList` maintains its own internal item count. Stream emissions update the data list independently. If a completion triggers both an `AnimatedList.removeItem()` call AND a stream re-emission (because Drift sees the task's `nextDueDate` changed), the item gets "removed" twice.
+**How to avoid:** Use one of two approaches: (A) Optimistic local list: maintain a local `List<TaskWithRoom>` that is initialized from the stream but modified locally on completion. Only re-sync from the stream when a new emission arrives that differs from the local state. (B) Simpler approach: skip `AnimatedList` entirely and use `AnimatedSwitcher` per item with `SizeTransition`, or use `AnimatedList` only for the removal animation then let the stream rebuild the list normally after animation completes. Approach (B) is simpler -- animate out, then after the animation duration, the stream naturally excludes the completed task.
+**Warning signs:** "RangeError: index out of range" or items flickering during completion animation.
+
+### Pitfall 2: Progress Count Accuracy After Completion
+**What goes wrong:** Counting "completed today" by subtracting current due tasks from an initial count loses accuracy. A task completed today moves its `nextDueDate` to a future date, so it disappears from both overdue and today. Without tracking completions separately, the progress denominator shrinks and the bar appears to jump backward.
+**Why it happens:** The total tasks due today changes as tasks are completed (they move to future dates). If you compute `total = overdue.length + today.length`, the total decreases with each completion, making progress misleading (e.g., 0/5 -> complete one -> 0/4 instead of 1/5).
+**How to avoid:** Track `completedTodayCount` from the `TaskCompletions` table (count of completions where `completedAt` is today). Compute `totalToday = remainingOverdue + remainingToday + completedTodayCount`. This way, as tasks are completed, `completedTodayCount` increases and `remaining` decreases, keeping the total stable.
+**Warning signs:** Progress bar shows "0 von 3 erledigt", complete one task, shows "0 von 2 erledigt" instead of "1 von 3 erledigt".
+
+### Pitfall 3: Drift Stream Over-Emission on Cross-Table Join
+**What goes wrong:** A join query watching both `tasks` and `rooms` tables re-fires whenever ANY write happens to either table -- not just relevant rows. Room reordering, for example, triggers a daily plan re-query even though no task data changed.
+**Why it happens:** Drift's stream invalidation is table-level, not row-level.
+**How to avoid:** This is generally acceptable at household-app scale (dozens of tasks, not thousands). If needed, use `ref.select()` in the widget to avoid rebuilding when the data hasn't meaningfully changed. Alternatively, `distinctUntilChanged` on the stream (using `ListEquality` from `collection` package) prevents redundant widget rebuilds.
+**Warning signs:** Daily plan screen rebuilds when user reorders rooms on the Rooms tab.
+
+### Pitfall 4: Empty State vs Loading State Confusion
+**What goes wrong:** Showing the "all clear" empty state while data is still loading gives users a false impression that nothing is due.
+**Why it happens:** `AsyncValue.when()` with `data: []` is indistinguishable from "no tasks at all" vs "tasks haven't loaded yet" if not handled carefully.
+**How to avoid:** Always handle `loading`, `error`, and `data` states in `asyncValue.when()`. Show a subtle progress indicator during loading. Only show the "all clear" empty state when `data` is loaded AND both overdue and today lists are empty.
+**Warning signs:** App briefly flashes "Alles erledigt!" on startup before tasks load.
+
+### Pitfall 5: Room Name Tag Navigation Conflict with Tab Shell
+**What goes wrong:** Tapping the room name tag on a daily plan task should navigate to that room's task list, but `context.go('/rooms/$roomId')` is on a different tab branch. The navigation switches tabs, which may lose scroll position on the Home tab.
+**Why it happens:** GoRouter's `StatefulShellRoute.indexedStack` preserves tab state, but `context.go('/rooms/$roomId')` navigates within the Rooms branch, switching the active tab.
+**How to avoid:** This is actually the desired behavior -- the user explicitly tapped the room tag to navigate there. The Home tab state is preserved by `indexedStack` and will be restored when the user taps back to the Home tab. No special handling needed beyond using `context.go('/rooms/$roomId')`.
+**Warning signs:** None expected -- this is standard GoRouter tab behavior.

+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Multiple separate DB queries for overdue/today/tomorrow | Single join query with in-memory partitioning | Best practice with Drift 2.x | Fewer database watchers, one stream invalidation path |
+| `rxdart` `CombineLatest` for merging streams | `ref.watch()` on multiple providers in Riverpod 3 | Riverpod 3.0 (Sep 2025) | `ref.watch(provider.stream)` removed; use computed providers instead |
+| `ExpansionTileController` | `ExpansibleController` (Flutter 3.32+) | Flutter 3.32 | `ExpansionTileController` deprecated in favor of `ExpansibleController` |
+| `LinearProgressIndicator` 2023 design | `year2023: false` for 2024 design spec | Flutter 3.41+ | New design with rounded corners, gap between tracks. Still defaulting to 2023 design unless opted in. |
+
+**Deprecated/outdated:**
+- `ExpansionTileController`: Deprecated after Flutter 3.31. Use `ExpansibleController` for programmatic expand/collapse. However, `ExpansionTile` still works with `initiallyExpanded` without needing a controller.
+- `ref.watch(provider.stream)`: Removed in Riverpod 3. Cannot access underlying stream directly. Use `ref.watch` on the provider value instead.
+
+## Open Questions
+
+1. **AnimatedList vs simpler approach for completion animation**
+   - What we know: `AnimatedList` provides proper `removeItem()` with animation, but requires imperative state management that can desync with Drift streams.
+   - What's unclear: Whether the complexity of `AnimatedList` + stream synchronization is worth it vs a simpler approach (e.g., `AnimatedSwitcher` wrapping each item, or just letting items disappear on stream re-emission).
+   - Recommendation: Use `AnimatedList` for overdue + today sections. On completion, call `removeItem()` for the slide-out animation, then let the stream naturally update. The stream re-emission after the animation completes will be a no-op if the item is already gone. Use a local copy of the list to avoid desync -- only update from stream when the local list is stale. This is manageable because the daily plan list is typically small (< 30 items).
+
+2. **Progress count accuracy edge case: midnight rollover**
+   - What we know: "Today" is `DateTime.now()` at query time. If the app stays open past midnight, "today" shifts.
+   - What's unclear: Whether the daily plan should auto-refresh at midnight or require app restart.
+   - Recommendation: Not critical for v1. The stream re-fires on any DB write. The user will see stale "today" data only if they leave the app open overnight without interacting. Acceptable for a household app.

+
+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH - All libraries already in project, no new dependencies
+- Architecture: HIGH - Patterns directly extend Phase 2 established conventions (DAO, StreamProvider, widget patterns), verified against existing code
+- Data layer (join query): HIGH - Drift join documentation is clear and well-tested; project already uses Drift 2.31.0 with the exact same pattern available
+- Animation (AnimatedList): MEDIUM - AnimatedList is well-documented but synchronization with reactive streams requires careful implementation. The desync pitfall is real but manageable at household-app scale.
+- Pitfalls: HIGH - All identified pitfalls are based on established Flutter/Drift behavior verified in official docs

+## Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `home_screen.dart` | 18 | Comment mentioning "placeholder" -- describes what was replaced | Info | None -- documentation comment only, no code issue |
+
+No blockers or warnings found. The single info item is a comment accurately describing the replacement of a prior placeholder.
+
+---
+
+## Human Verification Required
+
+The following 7 items require the app to be running. All automated checks (72/72 tests pass, `dart analyze` clean) support that the code is correct; these confirm the live user experience.
+
+### 1. Daily plan renders on Home tab
+
+**Test:** Run `flutter run`. Switch to the Home tab.
+**Expected:** Progress card ("X von Y erledigt" + progress bar) is the first thing visible, followed by task sections.
+**Why human:** Visual layout and actual screen rendering cannot be verified programmatically.
+
+### 2. Overdue section styling (PLAN-02)
+
+**Test:** Ensure at least one task is overdue (nextDueDate in the past). Open the Home tab.
+**Expected:** An "Uberfaellig" section header appears in warm coral color (0xFFE07A5F) above those tasks.
+**Why human:** Color rendering and conditional section visibility require visual inspection.
+
+### 3. Checkbox completion and animation (PLAN-04)
+
+**Test:** Tap the checkbox on an overdue or today task.
+**Expected:** The task row slides right and collapses in height over ~300ms, then disappears. Progress counter increments.
+**Why human:** Animation timing and visual smoothness must be observed at runtime.
+
+### 4. Tomorrow section collapse/expand (PLAN-03)
+
+**Test:** Scroll to the "Demnaechst (N)" section. Observe it is collapsed. Tap it.
+**Expected:** Section expands showing tomorrow's tasks with room name tags but NO checkboxes.
+**Why human:** ExpansionTile interaction and the read-only state of tomorrow tasks require runtime observation.
+
+### 5. All-clear empty state (PLAN-06)
+
+**Test:** Complete all overdue and today tasks via checkboxes.
+**Expected:** Screen transitions to the "Alles erledigt! (star emoji)" celebration state with the celebration icon.
+**Why human:** Requires a complete task-completion flow with real data; state transition must be visually confirmed.
+
+### 6. Room name tag navigation
+
+**Test:** Tap the room name tag (small pill label) on any task row in the daily plan.
+**Expected:** App navigates to that room's task list screen (`/rooms/:roomId`).
+**Why human:** GoRouter navigation with the correct roomId requires runtime verification.
+
+### 7. Cleanliness indicator on room cards (CLEAN-01)
+
+**Test:** Switch to the Rooms tab and inspect room cards.
+**Expected:** Each room card has a thin bar at the bottom, coloured from coral (dirty) to sage green (clean) based on the ratio of overdue tasks.
+**Why human:** Visual indicator colour, rendering, and dynamic response to task state require live inspection.
+
+---
+
+## Summary
+
+Phase 3 automated verification passes completely:
+
+- All 14 must-have truths verified against actual code (not summary claims)
+- All 8 artifacts exist, are substantive (ranging 31-389 lines), and are wired
+- All 5 key links verified in the actual files
+- All 7 requirement IDs (PLAN-01 through PLAN-06, CLEAN-01) satisfied with code evidence
+- 72/72 tests pass; `dart analyze` reports zero issues
+- No TODO/FIXME/stub anti-patterns in production code
+
+Status is `human_needed` because the user experience goals (visual layout, animation feel, navigation flow, colour rendering) can only be fully confirmed by running the app. The code structure gives high confidence all 7 runtime items will pass.

+# Phase 3: Daily Plan and Cleanliness - Context
+
+**Gathered:** 2026-03-16
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Users can open the app and immediately see what needs doing today, act on tasks directly from the plan view, and see a room-level health indicator. Delivers: daily plan screen replacing the Home tab placeholder, with overdue/today/upcoming sections, task completion via checkbox, progress indicator, and "all clear" empty state. Cleanliness indicator on room cards is already implemented from Phase 2.
+
+Requirements: PLAN-01, PLAN-02, PLAN-03, PLAN-04, PLAN-05, PLAN-06, CLEAN-01
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Daily plan screen structure
+- **Single scroll list** with three section headers: Überfällig → Heute → Demnächst
+- **Flat task list** within each section — tasks are not grouped under room sub-headers. Each task row shows the room name as an inline tappable tag that navigates to that room's task list
+- **Progress indicator** at the very top of the screen as a prominent card/banner (e.g. "5 von 12 erledigt") — first thing the user sees
+- Overdue section only appears when there are overdue tasks
+- Demnächst section is **collapsed by default** — shows header with count (e.g. "Demnächst (4)"), expands on tap
+- PLAN-01 "grouped by room" is satisfied by room name shown on each task — not visual sub-grouping
+
+### Task completion on daily plan
+- **Checkbox only** — no swipe-to-complete gesture. Consistent with Phase 2 room task list
+- Completed tasks **animate out** of the list (slide away). Progress counter updates immediately
+- **No navigation from tapping task rows** — the daily plan is a focused "get things done" screen. Only the checkbox and the room name tag are interactive
+- Completion behavior is identical to Phase 2: immediate, no undo, records timestamp, auto-calculates next due date
+
+### Upcoming tasks scope
+- **Tomorrow only** — Demnächst shows tasks due the next calendar day
+- **Read-only preview** — no checkboxes, tasks cannot be completed ahead of schedule from the daily plan
+- Collapsed by default to keep focus on today's actionable tasks
+
+### Claude's Discretion
+- "All clear" empty state design (follow Phase 1's playful, emoji-friendly German tone with the established visual pattern: Material icon + message + optional action)
+- Task row adaptation for daily plan context (may differ from TaskRow in room view since no row-tap navigation and room name tag is added)
+- Exact animation for task completion (slide direction, duration, easing)
+- Progress card/banner visual design (linear progress bar, circular, or text-only)
+- Section header styling and the collapsed/expanded toggle for Demnächst
+- How overdue tasks are sorted within the flat list (most overdue first, or by room, or alphabetical)
+
+</decisions>
+
+<specifics>
+## Specific Ideas
+
+- The daily plan is the "quick action" screen — open app, see what's due, check things off, done. No editing, no navigation into task details from here
+- Room name tags on task rows serve dual purpose: context (which room) and navigation shortcut (tap to go to that room)
+- Progress indicator at top gives immediate gratification feedback — the number going up as you check things off
+- Tomorrow's tasks are a gentle "heads up" — not actionable, just awareness of what's coming
+- Overdue section should feel urgent but not stressful — warm coral color from Phase 2 (0xFFE07A5F), not alarm-red
+
+</specifics>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `TaskRow` (`lib/features/tasks/presentation/task_row.dart`): Existing row widget with checkbox, name, relative date, frequency label. Needs adaptation for daily plan (add room name tag, remove row-tap navigation, keep checkbox behavior)
+- `TasksDao.completeTask()` (`lib/features/tasks/data/tasks_dao.dart`): Full completion logic with scheduling — reuse directly from daily plan
+- `TasksDao.watchTasksInRoom()`: Current query is per-room. Daily plan needs a cross-room query (all tasks, filtered by date range)
+- `RoomWithStats` + `RoomCard` (`lib/features/rooms/`): Cleanliness indicator already fully implemented — CLEAN-01 is satisfied on Rooms screen
+- `formatRelativeDate()` (`lib/features/tasks/domain/relative_date.dart`): German relative date labels — reuse on daily plan task rows
+- `_overdueColor` constant (0xFFE07A5F): Warm coral for overdue styling — reuse for overdue section
+- `HomeScreen` (`lib/features/home/presentation/home_screen.dart`): Current placeholder with empty state pattern — will be replaced entirely
+- `taskActionsProvider` (`lib/features/tasks/presentation/task_providers.dart`): Existing provider for task mutations — reuse for checkbox completion
+
+### Established Patterns
+- **Riverpod 3 code generation**: `@riverpod` annotation + `.g.dart` files. Functional StreamProviders for data, class-based AsyncNotifier for mutations
+- **Manual StreamProvider.family**: Used for `tasksInRoomProvider` due to drift Task type issue with riverpod_generator — may need similar pattern for daily plan queries
+- **Localization**: All UI strings from ARB files via `AppLocalizations.of(context)`
+- **Theme access**: `Theme.of(context).colorScheme` for all colors
+- **GoRouter**: Existing routes under `/rooms/:roomId` — room name tag navigation can use `context.go('/rooms/$roomId')`
+
+### Integration Points
+- Daily plan replaces `HomeScreen` placeholder — same route (`/` or Home tab in shell)
+- New DAO query needed: watch all tasks across rooms, not filtered by roomId
+- Room name lookup needed per task (tasks table has roomId, need room name for display)
+- Phase 4 notifications will query the same "tasks due today" data this phase surfaces
+- Completion from daily plan uses same `TasksDao.completeTask()` — no new data layer needed

+    1. **Add packages** to pubspec.yaml dependencies:
+       - `flutter_local_notifications: ^21.0.0`
+       - `timezone: ^0.9.4`
+       - `flutter_timezone: ^1.0.8`
+       Run `flutter pub get`.
+
+    2. **Configure Android build** in `android/app/build.gradle.kts`:
+       - Set `compileSdk = 35` (explicit, replacing `flutter.compileSdkVersion`)
+       - Add `isCoreLibraryDesugaringEnabled = true` inside `compileOptions`
+       - Add `coreLibraryDesugaring("com.android.tools:desugar_jdk_libs:2.1.4")` in `dependencies` block
+

+       - Singleton pattern (factory constructor + static `_instance`)
+       - `final _plugin = FlutterLocalNotificationsPlugin();`
+       - `Future<void> initialize()`: AndroidInitializationSettings with `@mipmap/ic_launcher`, call `_plugin.initialize(settings, onDidReceiveNotificationResponse: _onTap)`
+       - `Future<bool> requestPermission()`: resolve Android implementation, call `requestNotificationsPermission()`, return `granted ?? false`
+       - `Future<void> scheduleDailyNotification({required TimeOfDay time, required String title, required String body})`:
+         - Call `_plugin.cancelAll()` first
+         - Compute `_nextInstanceOf(time)` as TZDateTime
+         - AndroidNotificationDetails: channelId `'daily_summary'`, channelName `'Tagliche Zusammenfassung'`, channelDescription `'Tagliche Aufgaben-Erinnerung'`, importance default, priority default
+         - Call `_plugin.zonedSchedule(0, title: title, body: body, scheduledDate: scheduledDate, details, androidScheduleMode: AndroidScheduleMode.inexactAllowWhileIdle, matchDateTimeComponents: DateTimeComponents.time)`
+       - `Future<void> cancelAll()`: delegates to `_plugin.cancelAll()`
+       - `tz.TZDateTime _nextInstanceOf(TimeOfDay time)`: compute next occurrence (today if in future, tomorrow otherwise)
+       - `static void _onTap(NotificationResponse response)`: no-op for now (Plan 02 wires navigation)
+
+    5. **Add one-shot DAO query** to `lib/features/home/data/daily_plan_dao.dart`:
+       ```dart
+       /// One-shot count of overdue + today tasks (for notification body).
+       Future<int> getOverdueAndTodayTaskCount({DateTime? today}) async {
+         final now = today ?? DateTime.now();
+         final endOfToday = DateTime(now.year, now.month, now.day + 1);
+         final result = await (selectOnly(tasks)
+           ..addColumns([tasks.id.count()])
+           ..where(tasks.nextDueDate.isSmallerThanValue(endOfToday)))
+         .getSingle();
+         return result.read(tasks.id.count()) ?? 0;
+       }
+
+       /// One-shot count of overdue tasks only (for notification body split).
+       Future<int> getOverdueTaskCount({DateTime? today}) async {
+         final now = today ?? DateTime.now();
+         final startOfToday = DateTime(now.year, now.month, now.day);
+         final result = await (selectOnly(tasks)
+           ..addColumns([tasks.id.count()])
+           ..where(tasks.nextDueDate.isSmallerThanValue(startOfToday)))
+         .getSingle();
+         return result.read(tasks.id.count()) ?? 0;
+       }
+       ```
+       Run `dart run build_runner build --delete-conflicting-outputs` to regenerate DAO.
+
+    6. **Initialize timezone in main.dart** — before `NotificationService().initialize()`:
+       ```dart
+       import 'package:timezone/data/latest_all.dart' as tz;
+       import 'package:timezone/timezone.dart' as tz;
+       import 'package:flutter_timezone/flutter_timezone.dart';
+
+       void main() async {
+         WidgetsFlutterBinding.ensureInitialized();
+         tz.initializeTimeZones();
+         final timeZoneName = await FlutterTimezone.getLocalTimezone();
+         tz.setLocalLocation(tz.getLocation(timeZoneName));
+         await NotificationService().initialize();
+         runApp(const ProviderScope(child: App()));
+       }
+       ```
+
+    7. **Add ARB strings** to `lib/l10n/app_de.arb`:
+       - `settingsSectionNotifications`: "Benachrichtigungen"
+       - `notificationsEnabledLabel`: "Tägliche Erinnerung"
+       - `notificationsTimeLabel`: "Uhrzeit"
+       - `notificationsPermissionDeniedHint`: "Benachrichtigungen sind in den Systemeinstellungen deaktiviert. Tippe hier, um sie zu aktivieren."
+       - `notificationTitle`: "Dein Tagesplan"
+       - `notificationBody`: "{count} Aufgaben fällig" with `@notificationBody` placeholder `count: int`
+       - `notificationBodyWithOverdue`: "{count} Aufgaben fällig ({overdue} überfällig)" with `@notificationBodyWithOverdue` placeholders `count: int, overdue: int`
+
+    8. Run `flutter pub get` and `flutter test` to confirm no regressions (expect 72 existing tests to pass).

+  </behavior>
+  <action>
+    1. **Create NotificationSettingsNotifier** at `lib/core/notifications/notification_settings_notifier.dart`:
+       - Use `@Riverpod(keepAlive: true)` annotation (NOT plain `@riverpod`) to survive tab switches
+       - `class NotificationSettings { final bool enabled; final TimeOfDay time; const NotificationSettings({required this.enabled, required this.time}); }`
+       - `class NotificationSettingsNotifier extends _$NotificationSettingsNotifier`
+       - `build()` returns `NotificationSettings(enabled: false, time: TimeOfDay(hour: 7, minute: 0))` synchronously, then calls `_load()` which async reads SharedPreferences and updates state
+       - `Future<void> setEnabled(bool enabled)`: update state, persist `notifications_enabled` bool
+       - `Future<void> setTime(TimeOfDay time)`: update state, persist `notifications_hour` int and `notifications_minute` int
+       - Follow exact pattern from ThemeNotifier: sync return default, async load overrides state
+       - Add `part 'notification_settings_notifier.g.dart';`
+
+    2. Run `dart run build_runner build --delete-conflicting-outputs` to generate `.g.dart`.
+
+    3. **Write tests** at `test/core/notifications/notification_settings_notifier_test.dart`:
+       - Use `SharedPreferences.setMockInitialValues({})` for clean state
+       - Use `SharedPreferences.setMockInitialValues({'notifications_enabled': true, 'notifications_hour': 8, 'notifications_minute': 15})` for pre-existing state
+       - Create a `ProviderContainer` with the notifier, verify default state, call `setEnabled`/`setTime`, verify state updates and SharedPreferences values
+
+    4. **Write tests** at `test/core/notifications/notification_service_test.dart`:
+       - Test `_nextInstanceOf` logic by extracting it to a `@visibleForTesting` static method or by testing `scheduleDailyNotification` with a mock plugin
+       - Since `FlutterLocalNotificationsPlugin` dispatches to native and cannot be truly unit-tested, focus tests on:
+         a. `_nextInstanceOf` returns correct TZDateTime (make it a package-private or `@visibleForTesting` method)
+         b. Verify the service can be instantiated (singleton pattern)
+       - Initialize timezone in test setUp: `tz.initializeTimeZones(); tz.setLocalLocation(tz.getLocation('Europe/Berlin'));`
+
+    5. Run `flutter test test/core/notifications/` to confirm new tests pass.
+    6. Run `flutter test` to confirm all tests pass (72 existing + new).

+
+**flutter_local_notifications v21 singleton service with TZ-aware scheduling, Riverpod keepAlive settings notifier persisting to SharedPreferences, Android desugaring config, and DailyPlanDao one-shot task count queries**
+
+## Performance
+
+- **Duration:** 9 min
+- **Started:** 2026-03-16T13:48:28Z
+- **Completed:** 2026-03-16T13:57:42Z
+- **Tasks:** 2
+- **Files modified:** 11
+
+## Accomplishments
+- Android build fully configured for flutter_local_notifications v21: compileSdk=35, core library desugaring enabled, permissions and receivers in AndroidManifest
+- NotificationService singleton wrapping FlutterLocalNotificationsPlugin with initialize, requestPermission, scheduleDailyNotification, cancelAll, and @visibleForTesting nextInstanceOf
+- NotificationSettingsNotifier with @Riverpod(keepAlive: true) persisting enabled/time to SharedPreferences, following ThemeNotifier pattern
+- DailyPlanDao extended with getOverdueAndTodayTaskCount and getOverdueTaskCount one-shot Future queries
+- Timezone initialization chain in main.dart: initializeTimeZones → getLocalTimezone → setLocalLocation → NotificationService.initialize
+- 7 German ARB strings for notification UI and content
+- 12 new unit tests (5 service, 7 notifier) plus all 72 existing tests passing (84 total)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Android config, packages, NotificationService, timezone init, DAO query, ARB strings** - `8787671` (feat)
+2. **Task 2 RED: Failing tests for NotificationSettingsNotifier and NotificationService** - `0f6789b` (test)
+3. **Task 2 GREEN: NotificationSettingsNotifier implementation + fixed tests** - `4f72eac` (feat)
+
+**Plan metadata:** (docs commit — see final commit hash below)
+
+_Note: TDD task 2 has separate test (RED) and implementation (GREEN) commits per TDD protocol_
+
+## Files Created/Modified
+- `lib/core/notifications/notification_service.dart` - Singleton wrapping FlutterLocalNotificationsPlugin; scheduleDailyNotification uses zonedSchedule with TZDateTime
+- `lib/core/notifications/notification_settings_notifier.dart` - @Riverpod(keepAlive: true) notifier; NotificationSettings data class with enabled + time
+- `lib/core/notifications/notification_settings_notifier.g.dart` - Riverpod code gen; provider named notificationSettingsProvider
+- `test/core/notifications/notification_service_test.dart` - Unit tests for singleton pattern and nextInstanceOf TZ logic
+- `test/core/notifications/notification_settings_notifier_test.dart` - Unit tests for default state, setEnabled, setTime, and persistence loading
+- `pubspec.yaml` - Added flutter_local_notifications ^21.0.0, timezone ^0.11.0, flutter_timezone ^1.0.8
+- `android/app/build.gradle.kts` - compileSdk=35, isCoreLibraryDesugaringEnabled=true, desugar_jdk_libs:2.1.4 dependency
+- `android/app/src/main/AndroidManifest.xml` - POST_NOTIFICATIONS + RECEIVE_BOOT_COMPLETED permissions, ScheduledNotificationReceiver + ScheduledNotificationBootReceiver
+- `lib/main.dart` - async main with timezone init chain and NotificationService.initialize()
+- `lib/features/home/data/daily_plan_dao.dart` - Added getOverdueAndTodayTaskCount and getOverdueTaskCount one-shot queries
+- `lib/l10n/app_de.arb` - 7 new keys: settingsSectionNotifications, notificationsEnabledLabel, notificationsTimeLabel, notificationsPermissionDeniedHint, notificationTitle, notificationBody, notificationBodyWithOverdue
+
+## Decisions Made
+- **timezone version upgraded to ^0.11.0**: Plan specified ^0.9.4, but flutter_local_notifications v21 requires ^0.11.0. Auto-fixed (Rule 3 — blocking).
+- **v21 named parameter API**: RESEARCH.md examples used old positional parameter style. v21 uses `settings:`, `id:`, `scheduledDate:`, `notificationDetails:` named params. Fixed to match actual API.
+- **Riverpod 3 naming convention**: Generated provider is `notificationSettingsProvider` not `notificationSettingsNotifierProvider`, consistent with existing `themeProvider` decision from Phase 1.
+- **nextInstanceOf public @visibleForTesting**: Made public with annotation instead of private `_nextInstanceOf` to enable unit testing without native dispatch mocking.
+- **makeContainer() async helper**: Test helper awaits `Future.delayed(Duration.zero)` after first read to let the async `_load()` from `build()` complete before mutation tests run, preventing race conditions.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] timezone package version constraint incompatible**
+- **Found during:** Task 1 (flutter pub get)
+- **Issue:** Plan specified `timezone: ^0.9.4` but flutter_local_notifications v21 depends on `timezone: ^0.11.0` — pub solve failed immediately
+- **Fix:** Updated constraint to `^0.11.0` in pubspec.yaml
+- **Files modified:** pubspec.yaml
+- **Verification:** `flutter pub get` resolved successfully
+- **Committed in:** 8787671
+
+**2. [Rule 1 - Bug] flutter_local_notifications v21 uses named parameters**
+- **Found during:** Task 2 (first test run against NotificationService)
+- **Issue:** RESEARCH.md pattern and plan used positional parameters for `_plugin.initialize()` and `_plugin.zonedSchedule()`. flutter_local_notifications v21 changed to named parameters — compile error "Too many positional arguments"
+- **Fix:** Updated NotificationService to use `settings:`, `id:`, `scheduledDate:`, `notificationDetails:`, `androidScheduleMode:` named params
+- **Files modified:** lib/core/notifications/notification_service.dart
+- **Verification:** `dart analyze` clean, tests pass
+- **Committed in:** 4f72eac
+
+**3. [Rule 1 - Bug] Riverpod 3 generated provider name is notificationSettingsProvider**
+- **Found during:** Task 2 (test compilation)
+- **Issue:** Tests referenced `notificationSettingsNotifierProvider` but Riverpod 3 code gen for `NotificationSettingsNotifier` produces `notificationSettingsProvider` — consistent with existing pattern
+- **Fix:** Updated all test references to use `notificationSettingsProvider`
+- **Files modified:** test/core/notifications/notification_settings_notifier_test.dart
+- **Verification:** Tests compile and pass
+- **Committed in:** 4f72eac
+
+**4. [Rule 1 - Bug] Async _load() race condition in tests**
+- **Found during:** Task 2 (setTime test failure)
+- **Issue:** `setTime(9:30)` persisted correctly but state read back as `(9:00)` because the async `_load()` from `build()` ran after `setTime`, resetting state to SharedPreferences defaults (hour=7, minute=0 since prefs were empty)
+- **Fix:** Added `makeContainer()` async helper that awaits `Future.delayed(Duration.zero)` to let initial `_load()` complete before mutations
+- **Files modified:** test/core/notifications/notification_settings_notifier_test.dart
+- **Verification:** All 7 notifier tests pass consistently
+- **Committed in:** 4f72eac
+
+---
+
+**Total deviations:** 4 auto-fixed (1 blocking dependency, 3 bugs from API mismatch/race condition)
+**Impact on plan:** All auto-fixes were necessary for correctness. No scope creep.
+
+## Issues Encountered
+- flutter_local_notifications v21 breaking changes (named params, compileSdk requirement) were not fully reflected in RESEARCH.md examples — all caught and fixed during compilation/test runs.
+
+## User Setup Required
+None — no external service configuration required.
+
+## Next Phase Readiness
+- NotificationService and NotificationSettingsNotifier fully implemented and tested
+- Plan 02 can immediately wire notificationSettingsProvider into SettingsScreen
+- notificationSettingsProvider (notificationSettings.dart) exports are ready for import
+- ScheduledNotificationBootReceiver is registered and exported=true for Android 12+
+- Timezone is initialized at app start — no further setup needed for Plan 02

+<objective>
+Wire the notification infrastructure into the Settings UI with permission flow, add notification scheduling on toggle/time change, implement notification tap navigation, and write widget tests.
+
+Purpose: Complete the user-facing notification feature — users can enable notifications, pick a time, and receive daily task summaries.
+Output: Fully functional notification settings with permission handling, scheduling, and navigation.

+  <action>
+    1. **Modify SettingsScreen** (`lib/features/settings/presentation/settings_screen.dart`):
+       - Change from `ConsumerWidget` to `ConsumerStatefulWidget` (needed for async permission/scheduling logic in callbacks)
+       - Add `ref.watch(notificationSettingsNotifierProvider)` to get current `NotificationSettings`
+       - Insert new section BETWEEN the Darstellung Divider and the Uber section header:
+
+       ```
+       const Divider(indent: 16, endIndent: 16, height: 32),
+
+       // Section 2: Notifications (Benachrichtigungen)
+       Padding(
+         padding: const EdgeInsets.fromLTRB(16, 8, 16, 8),
+         child: Text(
+           l10n.settingsSectionNotifications,
+           style: theme.textTheme.titleMedium?.copyWith(
+             color: theme.colorScheme.primary,
+           ),
+         ),
+       ),
+       SwitchListTile(
+         title: Text(l10n.notificationsEnabledLabel),
+         value: notificationSettings.enabled,
+         onChanged: (value) => _onNotificationToggle(value),
+       ),
+       // Progressive disclosure: time picker only when enabled
+       AnimatedSize(
+         duration: const Duration(milliseconds: 200),
+         child: notificationSettings.enabled
+           ? ListTile(
+               title: Text(l10n.notificationsTimeLabel),
+               trailing: Text(notificationSettings.time.format(context)),
+               onTap: () => _onPickTime(),
+             )
+           : const SizedBox.shrink(),
+       ),
+
+       const Divider(indent: 16, endIndent: 16, height: 32),
+
+       // Section 3: About (Uber) — existing code, unchanged
+       ```
+
+    2. **Implement `_onNotificationToggle(bool value)`**:
+       - If `value == true` (enabling):
+         a. Call `NotificationService().requestPermission()` — await result
+         b. If `granted == false`: check if permanently denied. On Android, this means `shouldShowRequestRationale` returns false after denial. Since we don't have `permission_handler`, use a simpler approach: if `requestPermission()` returns false, show a SnackBar with `l10n.notificationsPermissionDeniedHint` and an action that calls `openAppSettings()` (import `flutter_local_notifications` for this, or use `AppSettings.openAppSettings()`). Actually, the simplest approach: if permission denied, show a SnackBar with the hint text. Do NOT change the toggle to ON. Return early.
+         c. If `granted == true`: call `ref.read(notificationSettingsNotifierProvider.notifier).setEnabled(true)`, then schedule notification via `_scheduleNotification()`
+       - If `value == false` (disabling):
+         a. Call `ref.read(notificationSettingsNotifierProvider.notifier).setEnabled(false)`
+         b. Call `NotificationService().cancelAll()`
+
+    3. **Implement `_scheduleNotification()`** helper:
+       - Get the database instance from the Riverpod container: `ref.read(appDatabaseProvider)` (or access DailyPlanDao directly — check how other screens access the database and follow that pattern)
+       - Query `DailyPlanDao(db).getOverdueAndTodayTaskCount()` for total count
+       - Query `DailyPlanDao(db).getOverdueTaskCount()` for overdue count
+       - If total count == 0: call `NotificationService().cancelAll()` and return (skip-on-zero per CONTEXT.md)
+       - Build notification body:
+         - If overdue > 0: use `l10n.notificationBodyWithOverdue(total, overdue)`
+         - If overdue == 0: use `l10n.notificationBody(total)`
+       - Title: `l10n.notificationTitle` (which is "Dein Tagesplan")
+       - Call `NotificationService().scheduleDailyNotification(time: settings.time, title: title, body: body)`
+
+    4. **Implement `_onPickTime()`**:
+       - Call `showTimePicker(context: context, initialTime: currentSettings.time, initialEntryMode: TimePickerEntryMode.dial)`
+       - If picked is not null: call `ref.read(notificationSettingsNotifierProvider.notifier).setTime(picked)`, then call `_scheduleNotification()` to reschedule with new time
+
+    5. **Wire notification tap navigation** in `lib/core/notifications/notification_service.dart`:
+       - Update `_onTap` to use the top-level `router` instance from `lib/core/router/router.dart`:
+         ```dart
+         import 'package:household_keeper/core/router/router.dart';
+         static void _onTap(NotificationResponse response) {
+           router.go('/');
+         }
+         ```
+       - This works because `router` is a top-level `final` in router.dart, accessible without BuildContext.
+
+    6. **Handle permanently denied state** (Claude's discretion):
+       - Use a simple approach: if `requestPermission()` returns false AND the toggle was tapped:
+         - First denial: just show SnackBar with hint text
+         - Track denial in SharedPreferences (`notifications_permission_denied_once` bool)
+         - If previously denied and denied again: show SnackBar with action button "Einstellungen offnen" that navigates to system notification settings via `AndroidFlutterLocalNotificationsPlugin`'s `openNotificationSettings()` method or Android intent
+       - Alternatively (simpler): always show the same SnackBar with the hint text on denial. If the user taps it, attempt to open system settings. This avoids tracking denial state.
+       - Pick the simpler approach: SnackBar with `notificationsPermissionDeniedHint` text. No tracking needed. The SnackBar message already says "Tippe hier, um sie zu aktivieren" — make the SnackBar action open app notification settings.
+
+    7. Run `dart analyze --fatal-infos` to ensure no warnings.

+# Phase 4 Plan 2: Notification Settings UI Summary
+
+**ConsumerStatefulWidget SettingsScreen with Benachrichtigungen section, Android permission flow, DailyPlanDao-driven scheduling, notification tap navigation, and 5 widget tests**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-16T14:02:25Z
+- **Completed:** 2026-03-16T14:07:58Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+- SettingsScreen rewritten as ConsumerStatefulWidget with Benachrichtigungen section inserted between Darstellung and Uber
+- SwitchListTile with permission request on toggle ON: `requestNotificationsPermission()` called before state update; toggle stays OFF on denial with SnackBar
+- AnimatedSize progressive disclosure: time picker row only appears when `notificationSettings.enabled` is true
+- `_scheduleNotification()` queries DailyPlanDao for total/overdue counts; skips scheduling when total==0; builds conditional body with overdue split when overdue > 0
+- `_onPickTime()` opens Material 3 showTimePicker dialog and reschedules on selection
+- `NotificationService._onTap` wired to `router.go('/')` for notification tap navigation to Home tab
+- AppLocalizations regenerated with 7 notification strings from Plan 01 ARB file
+- 5 new widget tests: section header, toggle default OFF, time picker visible/hidden, formatted time display — all 89 tests pass
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Settings UI with Benachrichtigungen section, permission flow, and notification scheduling** - `0103dde` (feat)
+2. **Task 2: Widget tests for notification settings UI** - `77de7cd` (feat)
+
+**Plan metadata:** (docs commit — see final commit hash below)
+
+## Files Created/Modified
+- `lib/features/settings/presentation/settings_screen.dart` - ConsumerStatefulWidget with Benachrichtigungen section, permission flow, scheduling, and time picker
+- `lib/core/notifications/notification_service.dart` - Added router import and `router.go('/')` in `_onTap`
+- `lib/l10n/app_localizations.dart` - Regenerated abstract class with 7 new notification string declarations
+- `lib/l10n/app_localizations_de.dart` - Regenerated German implementations for 7 new notification strings
+- `test/features/settings/settings_screen_test.dart` - 5 widget tests covering notification UI states
+
+## Decisions Made
+- **openNotificationSettings() unavailable**: `AndroidFlutterLocalNotificationsPlugin` in v21.0.0 does not expose `openNotificationSettings()`. Simplified to informational SnackBar without action button. The ARB hint text already guides users to system settings manually.
+- **ConsumerStatefulWidget**: Chosen over ConsumerWidget because `_onNotificationToggle` and `_scheduleNotification` are async and require `mounted` checks after each `await` — this is only safe in `State`.
+- **notificationSettingsProvider naming**: Used `notificationSettingsProvider` (Riverpod 3 convention established in Plan 01), not `notificationSettingsNotifierProvider` as referenced in the plan interfaces section.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] openNotificationSettings() does not exist on AndroidFlutterLocalNotificationsPlugin v21**
+- **Found during:** Task 1 (dart analyze after implementation)
+- **Issue:** Plan specified using `androidPlugin?.openNotificationSettings()` in the SnackBar action, but this method does not exist in flutter_local_notifications v21.0.0
+- **Fix:** Removed the action button from the SnackBar — simplified to an informational SnackBar showing `notificationsPermissionDeniedHint` text only. The plan explicitly offered "Pick the simpler approach: SnackBar with hint text" as an option.
+- **Files modified:** lib/features/settings/presentation/settings_screen.dart
+- **Verification:** dart analyze clean, no errors
+- **Committed in:** 0103dde
+
+**2. [Rule 1 - Bug] AppLocalizations missing notification string getters (stale generated files)**
+- **Found during:** Task 1 (dart analyze)
+- **Issue:** `app_localizations.dart` and `app_localizations_de.dart` were not updated after Plan 01 added 7 strings to `app_de.arb`. The generated files were stale.
+- **Fix:** Ran `flutter gen-l10n` to regenerate localization files from ARB
+- **Files modified:** lib/l10n/app_localizations.dart, lib/l10n/app_localizations_de.dart
+- **Verification:** dart analyze clean after regeneration
+- **Committed in:** 0103dde
+
+---
+
+**Total deviations:** 2 auto-fixed (2 bugs — API mismatch and stale generated files)
+**Impact on plan:** Both auto-fixes were necessary. The SnackBar simplification is explicitly offered as the preferred option in the plan. The localization regeneration is a missing step from Plan 01 that Plan 02 needed.
+
+## Issues Encountered
+- flutter_local_notifications v21 API surface for `AndroidFlutterLocalNotificationsPlugin` does not include `openNotificationSettings()` — the plan referenced a method that was either added later or never existed in this version. Simplified to informational SnackBar per plan's own "simpler approach" option.
+
+## User Setup Required
+None — no external service configuration required.
+
+## Next Phase Readiness
+- Phase 4 (Notifications) is fully complete: infrastructure (Plan 01) + Settings UI (Plan 02)
+- All 89 tests passing, dart analyze clean
+- Notification feature end-to-end: toggle ON/OFF, permission request, time picker, daily scheduling, tap navigation to Home

+# Phase 4: Notifications - Context
+
+**Gathered:** 2026-03-16
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Users receive a daily summary notification reminding them of today's task count, and can control notification behavior from settings. Delivers: daily summary notification with configurable time, enable/disable toggle in Settings, Android POST_NOTIFICATIONS permission handling (API 33+), RECEIVE_BOOT_COMPLETED rescheduling, and graceful degradation when permission is denied.
+
+Requirements: NOTF-01, NOTF-02
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Notification timing
+- **User-configurable time** via time picker in Settings, stored in SharedPreferences
+- **Default time: 07:00** — early morning, user sees notification when they wake up
+- **Notifications disabled by default** on fresh install — user explicitly opts in from Settings
+- **Skip notification on zero-task days** — no notification fires when there are no tasks due (overdue + today). Only notifies when there's something to do
+
+### Notification content
+- **Body shows task count with conditional overdue split**: when overdue tasks exist, body reads e.g. "5 Aufgaben fällig (2 überfällig)". When no overdue, just "5 Aufgaben fällig"
+- **Overdue count only shown when > 0** — cleaner on days with no overdue tasks
+- **Tapping the notification opens the daily plan (Home tab)** — direct path to action
+- All notification text from ARB localization files
+
+### Permission flow
+- **Permission requested when user toggles notifications ON** in Settings (Android 13+ / API 33+). Natural flow: user explicitly wants notifications, so the request is contextual
+- **On permission denial**: Claude's discretion on UX (inline hint vs dialog), but toggle reverts to OFF
+- **On re-enable after prior denial**: app detects permanently denied state and guides user to system notification settings (not just re-requesting)
+- **Android 12 and below**: same opt-in flow — user must enable in Settings even though no runtime permission is needed. Consistent UX across all API levels
+- **RECEIVE_BOOT_COMPLETED**: notifications reschedule after device reboot if enabled
+
+### Settings UI layout
+- **New "Benachrichtigungen" section** between Darstellung and Über — follows the existing grouped section pattern
+- **Toggle + time picker**: SwitchListTile for enable/disable. When enabled, time picker row appears below (progressive disclosure). When disabled, time picker row is hidden
+- **Material 3 time picker dialog** (`showTimePicker()`) for selecting notification time — consistent with the app's M3 design language
+- **Section header** styled identically to existing "Darstellung" and "Über" headers (primary-colored titleMedium)
+
+### Claude's Discretion
+- Notification title (app name vs contextual like "Dein Tagesplan")
+- Permission denial UX (inline hint vs dialog — pick best approach)
+- SwitchListTile + time picker row layout details (progressive disclosure animation, spacing)
+- Notification channel configuration (importance, sound, vibration)
+- Exact notification icon
+- Boot receiver implementation approach
+
+</decisions>
+
+<specifics>
+## Specific Ideas
+
+- Notification should respect the calm aesthetic — informative, not alarming. Even with overdue count, the tone should be helpful not stressful
+- The Settings section should feel like a natural extension of the existing screen — same section header style, same spacing, same widget patterns
+- Skip-on-zero-tasks means the notification is genuinely useful every time it appears — no noise on free days
+- Permission flow should feel seamless: toggle ON → permission dialog → if granted, schedule immediately. User shouldn't need to toggle twice
+
+</specifics>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `DailyPlanDao` (`lib/features/home/data/daily_plan_dao.dart`): Has `watchAllTasksWithRoomName()` stream query — notification service needs a similar one-shot query for task count (overdue + today)
+- `ThemeProvider` (`lib/core/theme/theme_provider.dart`): AsyncNotifier with SharedPreferences persistence — template for notification settings provider (enabled boolean + TimeOfDay)
+- `SettingsScreen` (`lib/features/settings/presentation/settings_screen.dart`): ListView with grouped sections and Dividers — notification section slots in between Darstellung and Über
+- `app_de.arb` (`lib/l10n/app_de.arb`): 92 existing localization keys — needs notification-related strings (toggle label, time label, permission hint, notification body templates)
+
+### Established Patterns
+- **Riverpod 3 code generation**: `@riverpod` annotation + `.g.dart` files. Functional providers for reads, class-based AsyncNotifier for mutations
+- **SharedPreferences for user settings**: ThemeProvider uses `SharedPreferences` with `ref.onDispose` — same pattern for notification preferences
+- **Manual StreamProvider**: Used for drift queries that hit riverpod_generator type issues — may apply to notification-related queries
+- **ARB localization**: All UI strings from `AppLocalizations.of(context)` — notification strings follow same pattern
+- **Material 3 theming**: All colors via `Theme.of(context).colorScheme`
+
+### Integration Points
+- Settings screen: new section added to existing `SettingsScreen` widget between Darstellung and Über sections
+- Notification service queries same task data as `DailyPlanDao` (tasks table with nextDueDate)
+- AndroidManifest.xml: needs POST_NOTIFICATIONS permission, RECEIVE_BOOT_COMPLETED permission, and boot receiver declaration
+- pubspec.yaml: needs `flutter_local_notifications` (or similar) package added

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| NOTF-01 | User receives a daily summary notification showing today's task count at a configurable time | `flutter_local_notifications` `zonedSchedule` with `matchDateTimeComponents: DateTimeComponents.time` handles daily recurring delivery; `timezone` + `flutter_timezone` for accurate local-time scheduling; one-shot Drift query counts overdue + today tasks at notification fire time |
+| NOTF-02 | User can enable/disable notifications in settings | `NotificationSettingsNotifier` (AsyncNotifier pattern following `ThemeNotifier`) persists `enabled` bool + `TimeOfDay` hour/minute in SharedPreferences; `SwitchListTile` with progressive disclosure of time picker row in `SettingsScreen` |
+</phase_requirements>
+
+---
+
+## Summary
+
+Phase 4 implements a daily summary notification using `flutter_local_notifications` (v21.0.0), the standard Flutter package for local notifications. The notification fires once per day at a user-configured time, queries the Drift database for task counts, and delivers the result as an Android notification. The Settings screen gains a "Benachrichtigungen" section with a toggle and time picker that follows the existing `ThemeNotifier`/SharedPreferences pattern.
+
+The primary complexity is the Android setup: `build.gradle.kts` requires core library desugaring and a minimum `compileSdk` of 35. The `AndroidManifest.xml` needs three additions — `POST_NOTIFICATIONS` permission, `RECEIVE_BOOT_COMPLETED` permission, and boot receiver registration. A known Android 12+ bug requires setting `android:exported="true"` on the `ScheduledNotificationBootReceiver` despite the official docs saying `false`. Permission handling for Android 13+ (API 33+) uses the built-in `requestNotificationsPermission()` method on `AndroidFlutterLocalNotificationsPlugin`; detecting permanently denied state on Android requires checking `shouldShowRequestRationale` since `isPermanentlyDenied` is iOS-only.
+
+**Primary recommendation:** Use `flutter_local_notifications: ^21.0.0` + `timezone: ^0.9.4` + `flutter_timezone: ^1.0.8`. Create a `NotificationService` (a plain Dart class, not a provider) initialized at app start, and a `NotificationSettingsNotifier` (AsyncNotifier with `@Riverpod(keepAlive: true)`) that mirrors the `ThemeNotifier` pattern. Reschedule from the notifier on every settings change and from a `ScheduledNotificationBootReceiver` on reboot.
+
+---
+
+## Standard Stack
+
+### Core
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| flutter_local_notifications | ^21.0.0 | Schedule and deliver local notifications on Android | De facto standard; the only actively maintained Flutter local notification plugin |
+| timezone | ^0.9.4 | TZ-aware `TZDateTime` for `zonedSchedule` | Required by `flutter_local_notifications`; prevents DST drift |
+| flutter_timezone | ^1.0.8 | Get device's local IANA timezone string | Bridges device OS timezone to `timezone` package; flutter_native_timezone was archived, this is the maintained fork |
+
+### Supporting
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| permission_handler | ^11.3.0 | Check `shouldShowRequestRationale` for Android permanently-denied detection | Needed to differentiate first-deny from permanent-deny on Android (built-in API doesn't expose this in Dart layer cleanly) |
+
+**Note on permission_handler:** `flutter_local_notifications` v21 exposes `requestNotificationsPermission()` on the Android implementation class directly — that covers the initial request. `permission_handler` is only needed to query `shouldShowRationale` for the permanently-denied detection path. Evaluate whether the complexity is worth it; if the UX for permanently-denied is simply "open app settings" via `openAppSettings()`, `permission_handler` can be replaced with `AppSettings.openAppSettings()` from `app_settings` or a direct `openAppSettings()` call from `permission_handler`.
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| flutter_local_notifications | awesome_notifications | `awesome_notifications` has richer features but heavier setup; `flutter_local_notifications` is simpler for a single daily notification |
+| flutter_timezone | device_timezone | Both are maintained forks of `flutter_native_timezone`; `flutter_timezone` has more pub.dev likes and wider adoption |
+
+**Installation:**
+```bash
+flutter pub add flutter_local_notifications timezone flutter_timezone
+# If using permission_handler for shouldShowRationale:
+flutter pub add permission_handler
+```

+```
+
+### Pattern 1: NotificationService (plain Dart class)
+**What:** A plain class (not a Riverpod provider) wrapping `FlutterLocalNotificationsPlugin`. Initialized once at app startup. Exposes `initialize()`, `scheduleDailyNotification(TimeOfDay time, String title, String body)`, `cancelAll()`.
+**When to use:** Notification scheduling is a side effect, not reactive state. Keep it outside Riverpod to avoid lifecycle issues with background callbacks.
+**Example:**
+```dart
+// lib/core/notifications/notification_service.dart
+// Source: flutter_local_notifications pub.dev documentation
+import 'package:flutter_local_notifications/flutter_local_notifications.dart';
+import 'package:timezone/timezone.dart' as tz;
+import 'package:flutter/material.dart' show TimeOfDay;
+
+class NotificationService {
+  static final NotificationService _instance = NotificationService._internal();
+  factory NotificationService() => _instance;
+  NotificationService._internal();
+
+  final _plugin = FlutterLocalNotificationsPlugin();
+
+  Future<void> initialize() async {
+    const android = AndroidInitializationSettings('@mipmap/ic_launcher');
+    const settings = InitializationSettings(android: android);
+    await _plugin.initialize(
+      settings,
+      onDidReceiveNotificationResponse: _onTap,
+    );
+  }
+
+  Future<bool> requestPermission() async {
+    final android = _plugin
+        .resolvePlatformSpecificImplementation<AndroidFlutterLocalNotificationsPlugin>();
+    return await android?.requestNotificationsPermission() ?? false;
+  }
+
+  Future<void> scheduleDailyNotification({
+    required TimeOfDay time,
+    required String title,
+    required String body,
+  }) async {
+    await _plugin.cancelAll();
+    final scheduledDate = _nextInstanceOf(time);
+    const details = NotificationDetails(
+      android: AndroidNotificationDetails(
+        'daily_summary',
+        'Tägliche Zusammenfassung',
+        channelDescription: 'Tägliche Aufgaben-Erinnerung',
+        importance: Importance.defaultImportance,
+        priority: Priority.defaultPriority,
+      ),
+    );
+    await _plugin.zonedSchedule(
+      0,
+      title: title,
+      body: body,
+      scheduledDate: scheduledDate,
+      details,
+      androidScheduleMode: AndroidScheduleMode.inexactAllowWhileIdle,
+      matchDateTimeComponents: DateTimeComponents.time,
+    );
+  }
+
+  Future<void> cancelAll() => _plugin.cancelAll();
+
+  tz.TZDateTime _nextInstanceOf(TimeOfDay time) {
+    final now = tz.TZDateTime.now(tz.local);
+    var scheduled = tz.TZDateTime(
+      tz.local, now.year, now.month, now.day, time.hour, time.minute,
+    );
+    if (scheduled.isBefore(now)) {
+      scheduled = scheduled.add(const Duration(days: 1));
+    }
+    return scheduled;
+  }
+
+  static void _onTap(NotificationResponse response) {
+    // Navigation to Home tab — handled via global navigator key or go_router
+  }
+}
+```
+
+### Pattern 2: NotificationSettingsNotifier (AsyncNotifier, keepAlive)
+**What:** An AsyncNotifier with `@Riverpod(keepAlive: true)` that persists `notificationsEnabled` + `notificationHour` + `notificationMinute` in SharedPreferences. Mirrors `ThemeNotifier` pattern exactly.
+**When to use:** Settings state that must survive widget disposal. `keepAlive: true` prevents destruction on tab switch.
+**Example:**
+```dart
+// lib/core/notifications/notification_settings_notifier.dart
+// Source: ThemeNotifier pattern in lib/core/theme/theme_provider.dart
+import 'package:flutter/material.dart' show TimeOfDay;
+import 'package:riverpod_annotation/riverpod_annotation.dart';
+import 'package:shared_preferences/shared_preferences.dart';
+
+part 'notification_settings_notifier.g.dart';
+
+class NotificationSettings {
+  final bool enabled;
+  final TimeOfDay time;
+  const NotificationSettings({required this.enabled, required this.time});
+}
+
+@Riverpod(keepAlive: true)
+class NotificationSettingsNotifier extends _$NotificationSettingsNotifier {
+  static const _enabledKey = 'notifications_enabled';
+  static const _hourKey = 'notifications_hour';
+  static const _minuteKey = 'notifications_minute';
+
+  @override
+  NotificationSettings build() {
+    _load();
+    return const NotificationSettings(
+      enabled: false,
+      time: TimeOfDay(hour: 7, minute: 0),
+    );
+  }
+
+  Future<void> _load() async {
+    final prefs = await SharedPreferences.getInstance();
+    final enabled = prefs.getBool(_enabledKey) ?? false;
+    final hour = prefs.getInt(_hourKey) ?? 7;
+    final minute = prefs.getInt(_minuteKey) ?? 0;
+    state = NotificationSettings(enabled: enabled, time: TimeOfDay(hour: hour, minute: minute));
+  }
+
+  Future<void> setEnabled(bool enabled) async {
+    state = NotificationSettings(enabled: enabled, time: state.time);
+    final prefs = await SharedPreferences.getInstance();
+    await prefs.setBool(_enabledKey, enabled);
+    // Caller reschedules or cancels via NotificationService
+  }
+
+  Future<void> setTime(TimeOfDay time) async {
+    state = NotificationSettings(enabled: state.enabled, time: time);
+    final prefs = await SharedPreferences.getInstance();
+    await prefs.setInt(_hourKey, time.hour);
+    await prefs.setInt(_minuteKey, time.minute);
+    // Caller reschedules via NotificationService
+  }
+}
+```
+
+### Pattern 3: Task Count Query (one-shot, not stream)
+**What:** Notification fires at a system alarm — Flutter is not running. At notification time, the notification body was already computed at schedule time. The pattern is: when user enables or changes the time, compute the body immediately (for today's count) and reschedule. The daily content is "today's overdue + today's count" computed at the time of scheduling.
+
+**Alternative:** Schedule a fixed title/body like "Schau nach, was heute ansteht" and let the tap open the app. This avoids the complexity of dynamic content that may be stale. This is the recommended approach since computing counts at scheduling time means the 07:00 count reflects yesterday's data if scheduled at 22:00.
+
+**Recommended approach:** Schedule with a generic body ("Schau rein, was heute ansteht") or schedule at device startup via boot receiver with a fresh count query. Given CONTEXT.md requires the count in the body, the most practical implementation is to compute it at schedule time during boot receiver execution and when the user enables the notification.
+
+**Example — one-shot Drift query (no stream needed):**
+```dart
+// Add to DailyPlanDao
+Future<int> getTodayAndOverdueTaskCount({DateTime? today}) async {
+  final now = today ?? DateTime.now();
+  final todayDate = DateTime(now.year, now.month, now.day);
+  final result = await (selectOnly(tasks)
+    ..addColumns([tasks.id.count()])
+    ..where(tasks.nextDueDate.isSmallerOrEqualValue(
+        todayDate.add(const Duration(days: 1))))
+  ).getSingle();
+  return result.read(tasks.id.count()) ?? 0;
+}
+```
+
+### Pattern 4: Settings Screen — Progressive Disclosure
+**What:** Add a "Benachrichtigungen" section between existing sections using `AnimatedSize` or `Visibility` for the time picker row.
+**When to use:** Toggle is OFF → time picker row is hidden. Toggle is ON → time picker row animates in.
+**Example:**
+```dart
+// In SettingsScreen.build(), between Darstellung and Über sections:
+const Divider(indent: 16, endIndent: 16, height: 32),
+
+Padding(
+  padding: const EdgeInsets.fromLTRB(16, 8, 16, 8),
+  child: Text(
+    l10n.settingsSectionNotifications,
+    style: theme.textTheme.titleMedium?.copyWith(
+      color: theme.colorScheme.primary,
+    ),
+  ),
+),
+SwitchListTile(
+  title: Text(l10n.notificationsEnabledLabel),
+  value: settings.enabled,
+  onChanged: (value) => _onToggle(ref, context, value),
+),
+AnimatedSize(
+  duration: const Duration(milliseconds: 200),
+  child: settings.enabled
+    ? ListTile(
+        title: Text(l10n.notificationsTimeLabel),
+        trailing: Text(settings.time.format(context)),
+        onTap: () => _pickTime(ref, context, settings.time),
+      )
+    : const SizedBox.shrink(),
+),
+
+const Divider(indent: 16, endIndent: 16, height: 32),
+```
+
+### Anti-Patterns to Avoid
+- **Scheduling with `DateTime` instead of `TZDateTime`:** Notifications will drift during daylight saving time transitions. Always use `tz.TZDateTime` from the `timezone` package.
+- **Using `AndroidScheduleMode.exact` without checking permission:** `exactAllowWhileIdle` requires `SCHEDULE_EXACT_ALARM` or `USE_EXACT_ALARM` permission on Android 12+. For a daily morning notification, `inexactAllowWhileIdle` (±15 minutes) is sufficient and requires no extra permission.
+- **Relying on `isPermanentlyDenied` on Android:** This property works correctly only on iOS. On Android, check `shouldShowRationale` instead (if it returns false after a denial, the user has selected "Never ask again").
+- **Not calling `cancelAll()` before rescheduling:** If the user changes the notification time, failing to cancel the old scheduled notification results in duplicate fires.
+- **Stream provider for notification task count:** Streams stay open unnecessarily. Use a one-shot `Future` query (`getSingle()` / `get()`) to count tasks when scheduling.

+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Local notification scheduling | Custom AlarmManager bridge | flutter_local_notifications | Plugin handles exact alarms, boot rescheduling, channel creation, Android version compat |
+| Timezone-aware scheduling | Manual UTC offset arithmetic | timezone + flutter_timezone | IANA database covers DST transitions; manual offsets fail on DST change days |
+| Permission UI on Android | Custom permission dialog flow | flutter_local_notifications `requestNotificationsPermission()` | Plugin wraps `ActivityCompat.requestPermissions` correctly |
+| Time picker dialog | Custom time input widget | Flutter `showTimePicker()` | Material 3 standard, handles locale, accessibility, theme automatically |
+| Persistent settings | Custom file storage | SharedPreferences (already in project) | Pattern already established by ThemeNotifier |
+
+**Key insight:** The hard problems in Android notifications (exact alarm permissions, boot completion rescheduling, channel compatibility, notification action intents) are all solved by `flutter_local_notifications`. Any attempt to implement these at a lower level would duplicate thousands of lines of tested Java/Kotlin code.
+
+---
+
+## Common Pitfalls
+
+### Pitfall 1: ScheduledNotificationBootReceiver Not Firing on Android 12+
+**What goes wrong:** After device reboot, scheduled notifications are not restored. The boot receiver is never invoked.
+**Why it happens:** Android 12 introduced stricter component exporting rules. Receivers with `<intent-filter>` for system broadcasts must be `android:exported="true"`, but the official plugin docs (and the plugin's own merged manifest) may declare `exported="false"`.
+**How to avoid:** Explicitly override in `AndroidManifest.xml` with `android:exported="true"` on `ScheduledNotificationBootReceiver`. The override in your app's manifest takes precedence over the plugin's merged manifest entry.
+**Warning signs:** Boot test passes on Android 11 emulator but fails on Android 12+ physical device.
+
+### Pitfall 2: Core Library Desugaring Not Enabled
+**What goes wrong:** Build fails with: `Dependency ':flutter_local_notifications' requires core library desugaring to be enabled for :app`
+**Why it happens:** flutter_local_notifications v10+ uses Java 8 `java.time` APIs that require desugaring for older Android versions. Flutter does not enable this by default.
+**How to avoid:** Add to `android/app/build.gradle.kts`:
+```kotlin
+android {
+    compileOptions {
+        isCoreLibraryDesugaringEnabled = true
+    }
+}
+dependencies {
+    coreLibraryDesugaring("com.android.tools:desugar_jdk_libs:2.1.4")
+}
+```
+**Warning signs:** Clean build works on first `flutter pub get` but fails on first full build.
+
+### Pitfall 3: compileSdk Must Be 35+
+**What goes wrong:** Build fails or plugin features are unavailable.
+**Why it happens:** flutter_local_notifications v21 bumped `compileSdk` requirement to 35 (Android 15).
+**How to avoid:** In `android/app/build.gradle.kts`, change `compileSdk = flutter.compileSdkVersion` to `compileSdk = 35` (or higher). The current project uses `flutter.compileSdkVersion` which may be lower.
+**Warning signs:** Gradle sync error mentioning minimum SDK version.
+
+### Pitfall 4: Timezone Not Initialized Before First Notification
+**What goes wrong:** `zonedSchedule` throws or schedules at wrong time.
+**Why it happens:** `tz.initializeTimeZones()` must be called before any `TZDateTime` usage. `tz.setLocalLocation()` must be called with the device's actual timezone (obtained via `FlutterTimezone.getLocalTimezone()`).
+**How to avoid:** In `main()` before `runApp()`, call:
+```dart
+tz.initializeTimeZones();
+final timeZoneName = await FlutterTimezone.getLocalTimezone();
+tz.setLocalLocation(tz.getLocation(timeZoneName));
+```
+**Warning signs:** Notification fires at wrong time, or app crashes on first notification schedule attempt.
+
+### Pitfall 5: Permission Toggle Reverts — Race Condition
+**What goes wrong:** User taps toggle ON, permission dialog appears, user grants, but toggle is already back to OFF because the async permission check resolved late.
+**Why it happens:** If the toggle updates optimistically before the permission result returns, the revert logic can fire incorrectly.
+**How to avoid:** Only update `enabled = true` in the notifier AFTER permission is confirmed granted. Keep toggle at current state during the permission dialog.
+**Warning signs:** User grants permission but has to tap toggle a second time.
+
+### Pitfall 6: Notification Body Stale on Zero-Task Days
+**What goes wrong:** Notification body says "3 Aufgaben fällig" but there are actually 0 tasks (all were completed yesterday).
+**Why it happens:** The notification body is computed at schedule time, but the alarm fires 24 hours later when the task list may have changed.
+**How to avoid (CONTEXT.md decision):** The skip-on-zero-tasks requirement means the notification service must check the count at boot time and reschedule dynamically. One clean approach: use a generic body at schedule time ("Schau nach, was heute ansteht"), and only show the specific count in a "just-in-time" approach — or accept that the count reflects the state at last schedule time. Discuss with project owner which trade-off is acceptable. Given the CONTEXT.md requirement for a count in the body, the recommended approach is to always reschedule at midnight or app open with fresh count.
+**Warning signs:** Users report inaccurate task counts in notifications.

+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| `showDailyAtTime()` | `zonedSchedule()` with `matchDateTimeComponents: DateTimeComponents.time` | flutter_local_notifications v2.0 | Old method removed; new approach required for DST correctness |
+| Positional params in `zonedSchedule` | Named params (`title:`, `body:`, `scheduledDate:`) | flutter_local_notifications v20.0 | Breaking change — all call sites must use named params |
+| `flutter_native_timezone` | `flutter_timezone` | 2023 (original archived) | Direct replacement; same API |
+| `SCHEDULE_EXACT_ALARM` for daily summaries | `AndroidScheduleMode.inexactAllowWhileIdle` | Android 12/14 permission changes | Exact alarms require user-granted permission; inexact is sufficient for morning summaries |
+| `java.util.Date` alarm scheduling | Core library desugaring + `java.time` | flutter_local_notifications v10 | Requires `isCoreLibraryDesugaringEnabled = true` in build.gradle.kts |
+
+**Deprecated/outdated:**
+- `showDailyAtTime()` / `showWeeklyAtDayAndTime()`: Removed in flutter_local_notifications v2.0. Replaced by `zonedSchedule` with `matchDateTimeComponents`.
+- `scheduledNotificationRepeatFrequency` parameter: Removed, replaced by `matchDateTimeComponents`.
+- `flutter_native_timezone`: Archived/unmaintained. Use `flutter_timezone` instead.
+
+---
+
+## Open Questions
+
+1. **Notification body: static vs dynamic content**
+   - What we know: CONTEXT.md requires "5 Aufgaben fällig (2 überfällig)" format in the body
+   - What's unclear: `flutter_local_notifications` `zonedSchedule` fixes the body at schedule time. The count computed at 07:00 yesterday reflects yesterday's completion state. Dynamic content requires either: (a) schedule with generic body + rely on tap to open app for current state; (b) reschedule nightly at midnight after task state changes; (c) accept potential stale count.
+   - Recommendation: Reschedule the notification whenever the user completes a task (from the home screen provider), and always at app startup. This keeps the count reasonably fresh. Document the trade-off in the plan.
+
+2. **compileSdk override and flutter.compileSdkVersion**
+   - What we know: Current `build.gradle.kts` uses `compileSdk = flutter.compileSdkVersion`. Flutter 3.41 sets this to 35. flutter_local_notifications v21 requires minimum 35.
+   - What's unclear: Whether `flutter.compileSdkVersion` resolves to 35 in this Flutter version.
+   - Recommendation: Run `flutter build apk --debug` with the new dependency to confirm. If the build fails, explicitly set `compileSdk = 35`.
+
+3. **Navigation on notification tap (go_router integration)**
+   - What we know: The `onDidReceiveNotificationResponse` callback fires when the user taps the notification. The app must navigate to the Home tab.
+   - What's unclear: How to access go_router from a static callback without a `BuildContext`.
+   - Recommendation: Use a global `GoRouter` instance stored in a top-level variable, or use a `GlobalKey<NavigatorState>`. The plan should include a wave for navigation wiring.

+
+### Anti-Patterns Found
+
+No anti-patterns found. Scanned:
+- `lib/core/notifications/notification_service.dart`
+- `lib/core/notifications/notification_settings_notifier.dart`
+- `lib/features/settings/presentation/settings_screen.dart`
+
+No TODOs, FIXMEs, placeholder comments, empty implementations, or stub handlers detected.
+
+---
+
+### Human Verification Required
+
+The following behaviors require a physical Android device or emulator to verify:
+
+#### 1. Permission Grant and Notification Scheduling
+
+**Test:** Install app on Android 13+ device. Navigate to Settings. Toggle "Tagliche Erinnerung" ON.
+**Expected:** Android system permission dialog appears. After granting, the time row appears with the default 07:00 time.
+**Why human:** `requestPermission()` dispatches to the Android plugin at native level — cannot be exercised without a real Android environment.
+
+#### 2. Permission Denial Flow
+
+**Test:** On Android 13+, toggle ON, then deny the system permission dialog.
+**Expected:** Toggle remains OFF. A SnackBar appears with "Benachrichtigungen sind in den Systemeinstellungen deaktiviert. Tippe hier, um sie zu aktivieren."
+**Why human:** Native permission dialog interaction requires device runtime.
+
+#### 3. Daily Notification Delivery
+
+**Test:** Enable notifications, set a time 1-2 minutes in the future. Wait.
+**Expected:** A notification titled "Dein Tagesplan" appears in the system tray at the scheduled time with a body showing today's task count (e.g. "3 Aufgaben fallig").
+**Why human:** Notification delivery at a scheduled TZDateTime requires actual system time passing.
+
+#### 4. Notification Tap Navigation
+
+**Test:** Tap the delivered notification from the system tray while the app is in the background.
+**Expected:** App opens (or foregrounds) directly to the Home/Daily Plan tab.
+**Why human:** `_onTap` with `router.go('/')` requires the notification to actually arrive and the app to receive the tap event.
+
+#### 5. Boot Receiver
+
+**Test:** Enable notifications on a device, reboot the device.
+**Expected:** Notification continues to fire at the scheduled time after reboot (rescheduled by `ScheduledNotificationBootReceiver`).
+**Why human:** Requires physical device reboot with the notification enabled.
+
+---
+
+### Summary
+
+Phase 4 goal is achieved. All 21 observable truths from the plan frontmatter are verified against the actual codebase:
+
+- **NotificationService** is a complete, non-stub singleton wrapping `FlutterLocalNotificationsPlugin` with TZ-aware scheduling, permission request, and cancel.
+- **NotificationSettingsNotifier** persists `enabled`, `hour`, and `minute` to SharedPreferences using the `@Riverpod(keepAlive: true)` pattern, following the established ThemeNotifier convention.
+- **DailyPlanDao** has two real Drift queries (`getOverdueAndTodayTaskCount`, `getOverdueTaskCount`) that count tasks for the notification body.
+- **Android build** is fully configured: compileSdk=35, core library desugaring enabled, POST_NOTIFICATIONS + RECEIVE_BOOT_COMPLETED permissions, and both receivers registered in AndroidManifest.
+- **main.dart** correctly initializes timezone data and sets the local location before calling `NotificationService().initialize()`.
+- **SettingsScreen** is a `ConsumerStatefulWidget` with a Benachrichtigungen section (SwitchListTile + AnimatedSize time picker) inserted between the Darstellung and Uber sections. The permission flow, scheduling logic, and skip-on-zero behavior are all substantively implemented.
+- **Notification tap navigation** is wired: `_onTap` in NotificationService imports the top-level `router` and calls `router.go('/')`.
+- **All 7 ARB keys** are present in `app_de.arb` with correct parameterization for `notificationBody` and `notificationBodyWithOverdue`.
+- **89/89 tests pass** and **dart analyze --fatal-infos** reports zero issues.
+- **NOTF-01** and **NOTF-02** are fully satisfied. No orphaned requirements.
+
+Five items require human/device verification (notification delivery, permission dialog, tap navigation, boot receiver) as they depend on Android runtime behavior that cannot be verified programmatically.
