+# App Audit — Fixes & Test Coverage
+
+**Branch**: `NDM-App-231-check-all-task-and-verify-if-is-everything-in-app`
+**Commits**: `ed4d988`, `c425e99`
+
+## What Was Done
+
+Full audit of the KittieMobile Flutter app. Small issues fixed in-place; larger missing features queued as AITM tasks.
+
+---
+
+## Direct Fixes Applied
+
+### 1. Router deduplication
+**File**: `lib/core/router/routes.dart`, `lib/core/router/app_router.dart`
+
+- Merged duplicate `Routes` class — it existed in both files. Canonical location is now `routes.dart` only.
+- Removed unused `Routes.home = '/'` constant (`initialLocation` already uses `Routes.tasks`).
+- Deleted orphaned generated files: `app_router.g.dart`, `pet_providers.g.dart`, `task_providers.g.dart` — they were generated by a mismatched Riverpod version and caused compile errors.
+
+### 2. PetType canonical import
+**Files**: `lib/features/onboarding/providers/onboarding_providers.dart`, `lib/features/onboarding/screens/onboarding_screen.dart`
+
+- Removed local re-declaration of `PetType` enum in onboarding providers.
+- Added import from canonical location: `lib/domain/entities/pet_type.dart`.
+
+### 3. FAB navigation fix
+**File**: `lib/features/tasks/screens/tasks_screen.dart`
+
+- FAB was calling `context.push(Routes.addTask)` — the route does not exist as a named route.
+- Changed to call `showAddTaskSheet(context)` directly (the bottom sheet function).
+
+### 4. Pet mood display fix
+**File**: `lib/features/tasks/screens/tasks_screen.dart`
+
+- `PetBubble` `mood` parameter was receiving `petMood.name` (raw enum string, e.g. `"happy"`).
+- Changed to `petMood.emoji` — now shows the actual emoji character.
+- `_petMessage` function signature updated to accept `PetMood` enum directly (exhaustive switch, no silent fall-through on future renames).
+
+### 5. Czech diacritics
+**Files**: `tasks_screen`, `energy_badge`, `task_card`, `app_shell`, `pet_screen`, `profile_screen`, `zen_screen`, `lib/domain/entities/pet_type.dart`, `lib/shared/utils/czech_date.dart`
+
+- Multiple UI strings had broken diacritics (e.g. `"Přidat úkol"` was corrupted).
+- All fixed in-place. `flutter analyze` confirmed no issues after fix.
+
+### 6. Entity alignment with DB schema
+**Files**: `lib/domain/entities/task_entity.dart`, `lib/domain/entities/user_entity.dart`
+
+- `TaskEntity.id` and `UserEntity.id` changed from `int` to `String` to match Drift UUID schema.
+- `TaskEntity` gained: `photoPath`, `snoozeUntil`, `syncedAt`, `localId`.
+- `UserEntity` gained: `deviceId`, `createdAt`, `updatedAt`.
+- `TasksNotifier` methods updated to accept `String` ids.
