# Phase 5 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | vitest 4.x (API + PWA) |
| **Config file** | `apps/api/vitest.config.*` / `apps/pwa/vitest.config.*` (existing) |
| **Quick run command** | `pnpm --filter @familysync/api test` |
| **Full suite command** | `pnpm --filter @familysync/api test && pnpm --filter @familysync/pwa test` |
| **Estimated runtime** | ~30 seconds |

---

## Sampling Rate

- **After every task commit:** Run quick run command for the touched workspace
- **After every plan wave:** Run full suite command
- **Before `/gsd-verify-work`:** Full suite must be green
- **Max feedback latency:** 30 seconds

---

## Per-Task Verification Map

> Populated by the planner from PLAN.md tasks. Each task with `<automated>` verify maps to a row.

| Task ID | Plan | Wave | Requirement | Threat Ref | Secure Behavior | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| TBD | — | — | NOTIF-01/02/03 | — | — | unit | `pnpm --filter @familysync/api test` | ❌ W0 | ⬜ pending |

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

---

## Wave 0 Requirements

- [ ] `web-push` + `@types/web-push` installed in `apps/api` before any push-dispatch task
- [ ] Test stubs for reminder scheduler, push-dispatch (VAPID sign + send), and subscription pruning (410/404)
- [ ] VAPID test keypair fixture for unit tests (no network)

*Existing vitest infrastructure covers the rest.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| iOS standalone-PWA push delivery + visible notification | NOTIF-01/02/03 | iOS Safari standalone push cannot be driven by playwright-cli (device-only) | Install PWA on iPhone (Home Screen), grant permission, trigger event reminder + list change, confirm visible notification |
| iOS subscription survives inactivity (health-check) | NOTIF (success criterion 4) | Requires real APNs + elapsed time on device | Leave PWA idle, fire push after extended inactivity, confirm still delivered |

*Desktop/Chromium push flows (permission prompt, subscribe, dispatch, notificationclick deep-link) ARE automatable via playwright-cli.*

---

## 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 < 30s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
