+# Phase 10 — 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** | vite.config.ts (vitest inline config) |
+| **Quick run command** | `npx vitest run --reporter=verbose` |
+| **Full suite command** | `npx vitest run` |
+| **Estimated runtime** | ~5 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `npx vitest run --reporter=verbose`
+- **After every plan wave:** Run `npx vitest run`
+- **Before `/gsd:verify-work`:** Full suite must be green
+- **Max feedback latency:** 10 seconds
+

+
+## Wave 0 Requirements
+
+- [ ] `src/components/ui/RemoteNamePreview.test.tsx` — stubs for UX-02 preview rendering
+
+*App.test.tsx, BackendSelectionStep.test.tsx, and RemoteConfigStep.test.tsx exist but need new test cases added as part of implementation tasks.*
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Intro section visual layout and spacing | UX-01 | Visual design verification | Open app, verify intro section appears with proper spacing, typography, and CTA button |
+| RemoteNamePreview updates live as user types | UX-02 | Real-time interaction verification | Type in remote name field, verify preview updates character by character |
+| Step descriptions are readable and contextually helpful | UX-03 | Content quality review | Navigate through all 4 steps, read each description for clarity and usefulness |
+| Tooltip content is accurate and helpful for each backend | UX-04 | Content accuracy review | Click tooltip buttons for each backend, verify text accuracy and doc links |
+
+---
+
+## 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 < 10s
+- [ ] `nyquist_compliant: true` set in frontmatter

+**Approval:** pending
