# Phase 29 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Bun test runner + Playwright |
| **Config file** | `bunfig.toml` / `playwright.config.ts` |
| **Quick run command** | `bun test` |
| **Full suite command** | `bun test && bun run test:e2e` |
| **Estimated runtime** | ~30 seconds (unit) + ~60 seconds (E2E) |

---

## Sampling Rate

- **After every task commit:** Run `bun test`
- **After every plan wave:** Run `bun test && bun run test:e2e`
- **Before `/gsd-verify-work`:** Full suite must be green
- **Max feedback latency:** 30 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Threat Ref | Secure Behavior | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| 29-01-01 | 01 | 1 | D-01,D-02,D-03 | — | N/A | unit | `bun test tests/services/image.service.test.ts` | ❌ W0 | ⬜ pending |
| 29-01-02 | 01 | 1 | D-04 | — | N/A | integration | `bun test tests/services/image.service.test.ts` | ❌ W0 | ⬜ pending |
| 29-02-01 | 02 | 1 | D-01,D-06 | — | N/A | grep | `grep -r "GearImage" src/client/` | N/A | ⬜ pending |
| 29-03-01 | 03 | 2 | D-07,D-08,D-09 | — | N/A | unit+E2E | `bun test && bun run test:e2e` | ❌ W0 | ⬜ pending |

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

## Wave 0 Requirements

- [ ] Test stubs for dominant color extraction service
- [ ] Test stubs for crop field persistence

*Existing test infrastructure (Bun test runner, Playwright) covers framework needs.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Dominant color background looks correct | D-02 | Visual quality subjective | Upload 5 varied images, verify background colors feel intentional |
| Zoom+pan editor is intuitive | D-07 | UX quality subjective | Open editor, zoom in/out, pan, verify coordinates save and render |
| Letterbox/pillarbox appearance | D-01 | Visual consistency check | View tall and wide images on cards and detail pages |

---

## 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
