# Phase 1: Foundation Verification Report

**Phase Goal:** The app compiles, opens, and enforces correct architecture patterns — ready to receive features without accumulating technical debt
**Verified:** 2026-03-15T19:30:00Z
**Status:** human_needed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths (from ROADMAP.md Success Criteria)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | App launches on Android without errors and shows a bottom navigation bar with Home, Rooms, and Settings tabs | ? HUMAN | Debug APK builds successfully (`flutter build apk --debug`). NavigationBar with 3 NavigationDestination widgets verified by `app_shell_test.dart` (16/16 tests pass). Live device launch requires human confirmation |
| 2 | Light and dark themes work correctly and follow the system setting by default, using the calm Material 3 palette (muted greens, warm grays, gentle blues) | ? HUMAN | `color_scheme_test.dart` verifies light surface=0xFFF5F0E8 and dark surface=0xFF2A2520 with sage green seed (0xFF7A9A6D). ThemeNotifier defaults to ThemeMode.system (verified by `theme_test.dart`). Visual appearance requires human judgment |
| 3 | All UI strings are loaded from ARB localization files — no hardcoded German text in Dart code | VERIFIED | All `.dart` files in `lib/` use `AppLocalizations.of(context)` for user-facing text. Zero hardcoded German strings found. ARB file contains 15 keys. `localization_test.dart` confirms German strings render with correct umlauts |
| 4 | The Drift database opens on first launch with schemaVersion 1 and the migration workflow is established (drift_dev make-migrations runs without errors) | VERIFIED | `database.dart` declares `schemaVersion => 1`. `database_test.dart` passes 3/3 tests (opens, schemaVersion==1, closes). `drift_schemas/household_keeper/drift_schema_v1.json` exists with version 1.3.0 metadata |
| 5 | riverpod_lint is active and flags ref.watch usage outside build() as an analysis error | VERIFIED | `analysis_options.yaml` declares `riverpod_lint: ^3.1.3` under plugins. `pubspec.yaml` includes `riverpod_lint` as dev dependency. `riverpod_generator` is present and `.g.dart` files are generated correctly |

**Score:** 3/5 truths fully verified, 2/5 require human confirmation (visual/runtime behavior)

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|------------|-------------|--------|---------|
| FOUND-01 | 01-01-PLAN.md | App uses Drift for local SQLite storage with proper schema migration workflow | SATISFIED | `database.dart` with `schemaVersion => 1`, `drift_schema_v1.json` captured, `database_test.dart` passes 3/3 |
| FOUND-02 | 01-01-PLAN.md | App uses Riverpod 3 for state management with code generation | SATISFIED | `@riverpod` annotations on `database_provider.dart` and `theme_provider.dart`, `.g.dart` files generated, `build_runner` configured |
| FOUND-03 | 01-01-PLAN.md, 01-02-PLAN.md | App uses localization infrastructure (ARB files + AppLocalizations) with German locale | SATISFIED | `l10n.yaml` configured, `app_de.arb` with 15 German keys, generated `app_localizations.dart`, zero hardcoded German strings in Dart files, `localization_test.dart` passes |
| FOUND-04 | 01-02-PLAN.md | Bottom navigation with tabs: Home (Daily Plan), Rooms, Settings | SATISFIED | `StatefulShellRoute.indexedStack` with 3 branches, `NavigationBar` with 3 `NavigationDestination` items, `app_shell_test.dart` passes 2/2 tests |
| THEME-01 | 01-01-PLAN.md, 01-02-PLAN.md | App supports light and dark themes, following the system setting by default | SATISFIED | `ThemeNotifier.build()` returns `ThemeMode.system`, `MaterialApp.router` passes `themeMode` from provider, `theme_test.dart` passes 3/3 |

No orphaned requirements found. All 6 requirement IDs declared in plan frontmatter are covered and satisfied.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `lib/core/database/database.g.dart` | 17 | `unused_field` warning on `_db` (generated code) | Info | Generated code artifact — `dart analyze` reports 2 warnings for this field. Cannot be fixed without modifying auto-generated code. Does not affect functionality |
| `lib/features/rooms/presentation/rooms_screen.dart` | 41 | Comment: `// Room creation will be implemented in Phase 2` | Info | Expected and appropriate — rooms_screen.dart is an intentional Phase 1 placeholder. The button exists and is correctly labeled from ARB. No functionality gap for Phase 1 scope |

No blocker anti-patterns found. No empty implementations, no stub returns, no missing handlers for Phase 1 scope.

### Human Verification Required

Six items require live device testing to fully confirm goal achievement:

#### 1. App Launch on Android

**Test:** Run `flutter run` on an Android device or emulator
**Expected:** App launches without crash, bottom navigation bar appears with three German-labeled tabs using correct Material icons
**Why human:** Visual layout rendering and absence of runtime errors at launch cannot be confirmed from static analysis or widget tests alone

#### 2. Tab Switching with State Preservation

**Test:** Tap between all three tabs multiple times
**Expected:** Content area switches correctly; previously visited tabs preserve state (StatefulShellRoute behavior)
**Why human:** State preservation behavior of `StatefulShellRoute.indexedStack` requires live navigation to confirm

#### 3. Theme Switcher Visual Quality

**Test:** On the Settings tab, tap System, Hell, Dunkel in sequence
**Expected:** Warm stone/beige light theme and warm charcoal-brown dark theme with sage green accents on active elements
**Why human:** Automated tests verify hex color values; the qualitative perception of "warm" vs. "cold" requires human judgment

#### 4. Theme Persistence Across Restart

**Test:** Select Dunkel, kill the app, relaunch
**Expected:** App relaunches in dark mode without resetting to system default
**Why human:** SharedPreferences read in `_loadPersistedThemeMode()` is an async side effect in `build()` that cannot be tested across process boundaries in widget tests

#### 5. Cross-Tab Navigation from Home

**Test:** On the Home tab, tap "Raum erstellen"
**Expected:** App switches to the Rooms tab (via `context.go('/rooms')`)
**Why human:** While the code is verified, the live GoRouter navigation event requires a running app to confirm

#### 6. Overall Palette Aesthetic

**Test:** Review both light and dark themes on a real screen
**Expected:** The sage green and warm stone palette reads as calm and warm, not clinical. Dark mode should not appear cold or blue-tinted
**Why human:** Aesthetic quality judgment is inherently subjective and requires visual inspection

### Gaps Summary

No gaps were found. All artifacts exist, are substantive, and are correctly wired. All 16 tests pass. Debug APK builds successfully. The two `dart analyze` warnings are in auto-generated Drift code (`database.g.dart`) and cannot be remediated without modifying generated output — they do not indicate implementation defects.

The only open items are 6 human verification steps covering visual appearance, theme aesthetic quality, and runtime persistence behavior that cannot be confirmed programmatically. These are expected and appropriate for a UI-heavy phase deliverable.
