# Phase 11 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Vitest 4.1.1 + @testing-library/react 16.3.2 |
| **Config file** | `vitest.config.ts` |
| **Quick run command** | `npx vitest run` |
| **Full suite command** | `npx vitest run` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `npx vitest run`
- **After every plan wave:** Run `npx vitest run`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 15 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 11-01-01 | 01 | 1 | POLISH-01 | unit (className) | `npx vitest run src/components/wizard/BackendSelectionStep.test.tsx` | ✅ needs new test | ⬜ pending |
| 11-01-02 | 01 | 1 | POLISH-01 | unit (DOM) | `npx vitest run src/components/wizard/BackendSelectionStep.test.tsx` | ✅ needs new test | ⬜ pending |
| 11-01-03 | 01 | 1 | POLISH-01 | unit (className) | `npx vitest run src/components/wizard/StepIndicator.test.tsx` | ✅ needs new test | ⬜ pending |
| 11-02-01 | 02 | 1 | POLISH-02 | unit (string check) | `npx vitest run` | ❌ W0 | ⬜ pending |
| 11-02-02 | 02 | 1 | POLISH-02 | unit (className) | `npx vitest run src/components/wizard/BackendSelectionStep.test.tsx` | ✅ needs new test | ⬜ pending |
| 11-03-01 | 03 | 1 | POLISH-03 | unit (DOM) | `npx vitest run src/App.test.tsx` | ✅ needs new test | ⬜ pending |
| 11-03-02 | 03 | 1 | POLISH-03 | manual | N/A | manual | ⬜ pending |
| 11-04-01 | 04 | 1 | POLISH-04 | unit | `npx vitest run src/components/wizard/BackendSelectionStep.test.tsx` | ✅ needs new test | ⬜ pending |

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

---

## Wave 0 Requirements

- [ ] Optional: `src/styles/md3-buttons.test.ts` — verify `focus-visible:ring-3` string in button constants

*Existing infrastructure covers most phase requirements. New test cases are added inline to existing test files.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| CSS @keyframes step-in defined in index.css | POLISH-03 | CSS animation definition not testable via jsdom | Inspect index.css for `@keyframes step-in` declaration |
| prefers-reduced-motion suppresses animation | POLISH-03 | Media query behavior not testable in jsdom | Check `@media (prefers-reduced-motion: reduce)` block exists in index.css |

---

## 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
