# Phase 1 — Validation Strategy

> Per-phase validation contract for feedback sampling during execution.

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | flutter_test (bundled with Flutter SDK) |
| **Config file** | none — Wave 0 creates test scaffolding |
| **Quick run command** | `flutter test` |
| **Full suite command** | `flutter test --coverage` |
| **Estimated runtime** | ~10 seconds |

---

## Sampling Rate

- **After every task commit:** Run `flutter test`
- **After every plan wave:** Run `flutter test --coverage`
- **Before `/gsd:verify-work`:** Full suite must be green + `dart analyze` clean (zero riverpod_lint issues)
- **Max feedback latency:** 15 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| TBD | 01 | 0 | FOUND-01 | unit + smoke | `flutter test test/core/database/database_test.dart` | No — Wave 0 | ⬜ pending |
| TBD | 01 | 0 | FOUND-02 | smoke | `dart analyze` | No — Wave 0 | ⬜ pending |
| TBD | 01 | 0 | FOUND-03 | widget | `flutter test test/l10n/localization_test.dart` | No — Wave 0 | ⬜ pending |
| TBD | 01 | 0 | FOUND-04 | widget | `flutter test test/shell/app_shell_test.dart` | No — Wave 0 | ⬜ pending |
| TBD | 01 | 0 | THEME-01 | widget | `flutter test test/core/theme/theme_test.dart` | No — Wave 0 | ⬜ pending |
| TBD | 01 | 0 | THEME-02 | unit | `flutter test test/core/theme/color_scheme_test.dart` | No — Wave 0 | ⬜ pending |

## Wave 0 Requirements

- [ ] `test/core/database/database_test.dart` — covers FOUND-01 (database opens, schema version correct)
- [ ] `test/l10n/localization_test.dart` — covers FOUND-03 (German strings load from ARB)
- [ ] `test/shell/app_shell_test.dart` — covers FOUND-04 (navigation bar renders 3 tabs)
- [ ] `test/core/theme/theme_test.dart` — covers THEME-01 (light/dark/system switching)
- [ ] `test/core/theme/color_scheme_test.dart` — covers THEME-02 (sage green seed, warm surfaces)
- [ ] Drift migration test scaffolding via `dart run drift_dev make-migrations` (auto-generated)

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Warm dark mode visual appearance | THEME-02 | Color perception is subjective — hex values pass tests but need visual review | Launch app, toggle to dark mode, verify charcoal-brown feel (not cold/blue-gray) |
| Thematic tab icons look correct | FOUND-04 | Icon selection is a design judgment | Launch app, verify clipboard/door/sliders icons match household domain |

---

## Validation Sign-Off

- [ ] All tasks have `<automated>` verify or Wave 0 dependencies
- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
- [ ] Wave 0 covers all MISSING references
- [ ] No watch-mode flags
- [ ] Feedback latency < 15s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
