# Phase 17 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Bun test runner |
| **Quick run command** | `bun test tests/services/storage.service.test.ts` |
| **Full suite command** | `bun test` |
| **Estimated runtime** | ~30 seconds |

---

## Sampling Rate

- **After every task commit:** Run `bun test tests/services/storage.service.test.ts tests/routes/images.test.ts`
- **After every plan wave:** Run `bun test`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 30 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 17-01-01 | 01 | 1 | IMG-04 | manual | `docker compose up -d && curl MinIO health` | N/A | ⬜ pending |
| 17-01-02 | 01 | 1 | IMG-01 | unit | `bun test tests/services/storage.service.test.ts` | ❌ W0 | ⬜ pending |
| 17-02-01 | 02 | 2 | IMG-01 | integration | `bun test tests/routes/images.test.ts` | ✅ (needs update) | ⬜ pending |
| 17-02-02 | 02 | 2 | IMG-03 | integration | `bun test tests/routes/items.test.ts` | ✅ (needs update) | ⬜ pending |
| 17-03-01 | 03 | 3 | IMG-02 | integration | Migration script test | ❌ W0 | ⬜ pending |

## Wave 0 Requirements

- [ ] `tests/services/storage.service.test.ts` — mock S3Client, test upload/delete/getUrl
- [ ] Update `tests/routes/images.test.ts` — verify routes call storage service
- [ ] Update `tests/routes/items.test.ts` — verify imageUrl in responses

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| MinIO starts in Docker Compose | IMG-04 | Requires Docker runtime | Run docker-compose.dev.yml, verify MinIO health endpoint |
| Existing images accessible after migration | IMG-02 | Requires real migration against uploads/ | Run migration script, verify images load in browser |

---

## Validation Sign-Off

- [ ] All tasks have `<automated>` verify or Wave 0 dependencies
- [ ] Sampling continuity maintained
- [ ] Wave 0 covers all MISSING references
- [ ] Feedback latency < 30s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
