# Phase 4 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | flutter_test (built-in) |
| **Config file** | none — uses flutter test runner |
| **Quick run command** | `flutter test test/core/notifications/` |
| **Full suite command** | `flutter test` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `flutter test test/core/notifications/`
- **After every plan wave:** Run `flutter test`
- **Before `/gsd:verify-work`:** Full suite must be green + `dart analyze --fatal-infos`
- **Max feedback latency:** 15 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 04-01-01 | 01 | 1 | NOTF-01 | unit | `flutter test test/core/notifications/notification_service_test.dart` | ❌ W0 | ⬜ pending |
| 04-01-02 | 01 | 1 | NOTF-01 | unit | `flutter test test/core/notifications/notification_service_test.dart` | ❌ W0 | ⬜ pending |
| 04-01-03 | 01 | 1 | NOTF-02 | unit | `flutter test test/core/notifications/notification_settings_notifier_test.dart` | ❌ W0 | ⬜ pending |
| 04-01-04 | 01 | 1 | NOTF-02 | unit | `flutter test test/core/notifications/notification_settings_notifier_test.dart` | ❌ W0 | ⬜ pending |

*Status: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky*

## Wave 0 Requirements

- [ ] `test/core/notifications/notification_service_test.dart` — stubs for NOTF-01 scheduling logic
- [ ] `test/core/notifications/notification_settings_notifier_test.dart` — stubs for NOTF-02 persistence
- [ ] `lib/core/notifications/notification_service.dart` — service stub for testing
- [ ] `android/app/build.gradle.kts` — add desugaring dependency
- [ ] `android/app/src/main/AndroidManifest.xml` — permissions + receivers
- [ ] Framework install: `flutter pub add flutter_local_notifications timezone flutter_timezone`

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Boot receiver manifest entry present (exported=true) | NOTF-01 | Static XML config, not runtime testable | Inspect AndroidManifest.xml for `ScheduledNotificationBootReceiver` with `android:exported="true"` |
| POST_NOTIFICATIONS permission requested on toggle-on | NOTF-01 | Native Android permission dialog | Run on Android 13+ emulator, toggle notification ON, verify dialog appears |
| Notification actually appears on device | NOTF-01 | flutter_local_notifications dispatches to native | Run on emulator, schedule notification 1 min ahead, verify it appears |

---

## 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
