+# Phase 3 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | Vitest ^4.1.1 |
+| **Config file** | none — Wave 0 adds `test: { environment: 'jsdom', passWithNoTests: true }` to `vite.config.ts` |
+| **Quick run command** | `npx vitest run --reporter=verbose` |
+| **Full suite command** | `npx vitest run` |
+| **Estimated runtime** | ~10 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:** 15 seconds
+
+---

+
+## Wave 0 Requirements
+
+- [ ] `vite.config.ts` — add `test: { environment: 'jsdom', passWithNoTests: true }` (required for all React component tests)
+- [ ] `src/App.test.tsx` — stubs for WIZD-02: step routing by currentStep
+- [ ] `src/components/wizard/BackendSelectionStep.test.tsx` — stubs for WIZD-01, WIZD-04
+- [ ] `src/components/wizard/RemoteConfigStep.test.tsx` — stubs for BACK-01, BACK-02, BACK-03
+- [ ] `src/components/wizard/StepIndicator.test.tsx` — stubs for WIZD-03
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Full wizard flow end-to-end (select → configure → deploy options) | WIZD-02 | Integration across step transitions | Open app, select Azure Blob, fill config, click Next through all steps, click Back, verify values preserved |
+| Azure auth toggle field preservation | BACK-01 | Requires visual + state verification | Select Azure, enter SAS URL, toggle to access key, enter key, navigate Back then Next, verify both values in form |
+
+---
+
+## 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
