+# 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
+
+---
+
+## Per-Task Verification Map
+
+| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
+|---------|------|------|-------------|-----------|-------------------|-------------|--------|
+| 09-01-01 | 01 | 0 | COMP-01 | unit | `npx vitest run src/components/ui/TextFieldMD3.test.tsx` | ❌ W0 | ⬜ pending |
+| 09-01-02 | 01 | 0 | COMP-03 | unit | `npx vitest run src/components/ui/BackendCard.test.tsx` | ❌ W0 | ⬜ pending |
+| 09-01-03 | 01 | 0 | DEBT-01 | unit | `npx vitest run src/components/ui/FieldRenderer.test.tsx` | ❌ W0 | ⬜ pending |
+| 09-02-01 | 01 | 1 | COMP-01 | unit | `npx vitest run src/components/ui/TextFieldMD3.test.tsx` | ❌ W0 | ⬜ pending |
+| 09-02-02 | 01 | 1 | COMP-01 | unit | `npx vitest run src/components/wizard/RemoteConfigStep.test.tsx` | ✅ | ⬜ pending |

+
+## 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
