# Phase 2 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Vitest 4.0.18 + @testing-library/react 16.3.2 |
| **Config file** | `frontend/vite.config.ts` (test section present) |
| **Quick run command** | `cd frontend && bun vitest run --reporter=verbose` |
| **Full suite command** | `cd frontend && bun vitest run` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `cd frontend && bun vitest run --reporter=verbose`
- **After every plan wave:** Run `cd frontend && bun vitest run && bun run build`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 15 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 02-00-01 | 00 | 0 | AUTH-01, AUTH-02, AUTH-04 | unit stub | `bun vitest run src/pages/LoginPage.test.tsx` | ❌ W0 | ⬜ pending |

| 02-02-04 | 02 | 1 | NAV-04 | unit | `bun vitest run src/components/AppLayout.test.tsx` | ❌ W0 | ⬜ pending |

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

## Wave 0 Requirements

- [ ] `frontend/src/pages/LoginPage.test.tsx` — stubs for AUTH-01, AUTH-02, AUTH-04
- [ ] `frontend/src/pages/RegisterPage.test.tsx` — stubs for AUTH-03
- [ ] `frontend/src/components/AppLayout.test.tsx` — stubs for NAV-01, NAV-02, NAV-03, NAV-04
- [ ] `frontend/src/components/ui/alert.tsx` — must exist before any test imports it (install via `bunx --bun shadcn add alert`)

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Gradient background visually reads as pastel | AUTH-01 | Visual quality judgment | Open login page in browser; gradient should feel like tinted paper, not a colorful splash |
| Wordmark gradient text is legible and branded | AUTH-02 | Visual quality judgment | App name should display with gradient color fill; text must not disappear |
| Active nav item is clearly distinguishable | NAV-03 | Contrast perception | Click different nav items; active state must produce a perceptible visual change |
| Sidebar collapse animation is smooth | NAV-04 | Animation quality | Click SidebarTrigger; sidebar should animate smoothly without content jumps |

---

## 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
