# Phase 5 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Vitest 4.1.1 |
| **Config file** | `vitest.config.ts` (root) |
| **Quick run command** | `npx vitest run src/components/wizard/BackendSelectionStep.test.tsx src/components/wizard/ReviewStep.test.tsx src/schemas/registry.test.ts` |
| **Full suite command** | `npx vitest run` |
| **Estimated runtime** | ~4 seconds |

---

## Sampling Rate

- **After every task commit:** Run `npx vitest run` (full suite — ~3.4s, fast enough for every commit)
- **After every plan wave:** Run `npx vitest run` + `npx tsc --noEmit`
- **Before `/gsd:verify-work`:** Full suite must be green + zero TypeScript errors
- **Max feedback latency:** ~4 seconds

| 5-W0-02 | W0 | 0 | TECH-02 | unit | `npx vitest run src/components/wizard/ReviewStep.test.tsx` | ❌ W0 | ⬜ pending |
| 5-W0-03 | W0 | 0 | TECH-03 | unit | `npx vitest run src/schemas/registry.test.ts` | ❌ W0 | ⬜ pending |
| 5-01-01 | 01 | 1 | TECH-01 | unit | `npx vitest run src/components/wizard/ReviewStep.test.tsx` | ❌ W0 | ⬜ pending |

| 5-03-01 | 03 | 1 | TECH-04 | type-check | `npx tsc --noEmit` | ✅ | ⬜ pending |
| 5-04-01 | 04 | 1 | TECH-05 | unit | `npx vitest run src/components/wizard/BackendSelectionStep.test.tsx 2>&1 \| grep -c "act("` | ✅ | ⬜ pending |

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

## Wave 0 Requirements

- [ ] `src/components/wizard/ReviewStep.test.tsx` — add cases for TECH-01: intune-only, rmm-only, neither (dispatch SET_DEPLOYMENT in test setup)
- [ ] `src/components/wizard/ReviewStep.test.tsx` — add case for TECH-02: Back button renders and dispatches SET_STEP(2)
- [ ] `src/schemas/registry.test.ts` — update field access to `.fields` after TECH-03 shape change

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Back button returns to DeploymentStep without losing form data | TECH-02 | Form state persistence across navigation is hard to assert purely in unit tests | 1. Fill in DeploymentStep fields, 2. Advance to ReviewStep, 3. Click Back, 4. Verify DeploymentStep values are intact |

---

## 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 < 4s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
