# Phase 9 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Vitest 4.1.1 |
| **Config file** | `vite.config.ts` (has `test.environment: jsdom`) |
| **Quick run command** | `npx vitest run --reporter=dot` |
| **Full suite command** | `npx vitest run` |
| **Estimated runtime** | ~7 seconds |

---

## Sampling Rate

- **After every task commit:** Run `npx vitest run --reporter=dot`
- **After every plan wave:** Run `npx vitest run`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 7 seconds

## Wave 0 Requirements

- [ ] `src/components/ui/TextFieldMD3.test.tsx` — stubs for COMP-01 floating label behavior
- [ ] `src/components/ui/BackendCard.test.tsx` — stubs for COMP-03 elevation class presence
- [ ] `src/components/ui/FieldRenderer.test.tsx` — stubs for DEBT-01 aria-label consistency

*Existing StepIndicator.test.tsx covers COMP-04 behavioral requirements. Update to match rebuilt component's button textContent if needed.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Floating label animation smoothness | COMP-01 | CSS transition quality is visual | Focus input, observe label floats up smoothly (~150ms) |
| Button visual hierarchy distinction | COMP-02 | Color/weight differences are visual | Compare primary (filled), secondary (outlined), tertiary (text) side by side |
| MD3 elevation tonal surface tint | COMP-03 | Subtle shadow/tint is visual | Check cards have visible elevation and surface tint |
| Step indicator visual states | COMP-04 | Checkmark/circle/line rendering is visual | Navigate wizard, verify completed=checkmark, current=highlighted, future=muted |

## 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 < 7s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
