# Phase 12 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Vitest ^4.1.1 (node environment) + @testing-library/react |
| **Config file** | `vitest.config.ts` |
| **Quick run command** | `npm test -- --reporter=verbose` |
| **Full suite command** | `npm test` |
| **Estimated runtime** | ~10 seconds |

---

## Sampling Rate

- **After every task commit:** Run `npm test -- --reporter=verbose`
- **After every plan wave:** Run `npm test`
- **Before `/gsd:verify-work`:** Full suite must be green + visual browser verification in dark mode
- **Max feedback latency:** 10 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 12-01-01 | 01 | 1 | h2 headings visible in dark mode | unit | `npm test -- src/components/wizard/BackendSelectionStep` | ✅ | ⬜ pending |
| 12-01-02 | 01 | 1 | h2 headings visible in dark mode | unit | `npm test -- src/components/wizard/RemoteConfigStep` | ✅ | ⬜ pending |
| 12-01-03 | 01 | 1 | h2 headings visible in dark mode | unit | `npm test -- src/components/wizard/DeploymentStep` | ✅ | ⬜ pending |
| 12-01-04 | 01 | 1 | h2 headings visible in dark mode | unit | `npm test -- src/components/wizard/ReviewStep` | ✅ | ⬜ pending |
| 12-01-05 | 01 | 1 | DeploymentStep labels/controls visible | unit | `npm test -- src/components/wizard/DeploymentStep` | ✅ | ⬜ pending |
| 12-01-06 | 01 | 1 | Select element styled for dark mode | unit | `npm test -- src/components/ui/FieldRenderer` | ✅ | ⬜ pending |
| 12-01-07 | 01 | 1 | ReviewStep checkbox styled | unit | `npm test -- src/components/wizard/ReviewStep` | ✅ | ⬜ pending |

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

## Wave 0 Requirements

Existing infrastructure covers all phase requirements. No new test files or fixtures needed.

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Dark mode visual correctness | All elements visible on dark bg | jsdom does not resolve CSS custom properties | Toggle dark mode in browser, verify all headings/labels/controls are readable on dark background |
| Select dropdown appearance | Select bg/text correct in dark mode | Native `<option>` rendering is browser-dependent | Open select in dark mode on Chrome/Edge, verify text is legible |
| Native checkbox/radio accent | Controls use primary accent color | CSS `accent-color` not testable in jsdom | Toggle checkboxes/radios in dark mode, verify accent color matches primary theme |

---

## 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
