# Phase 1 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | None — no test framework installed |
| **Config file** | none |
| **Quick run command** | `npm run build` |
| **Full suite command** | `npm run build && npm run lint` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `npm run build`
- **After every plan wave:** Run `npm run build && npm run lint`
- **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 |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 01-01-01 | 01 | 1 | UI-DESIGN-01 | build | `npm run build` | N/A | ⬜ pending |
| 01-01-02 | 01 | 1 | UI-DESIGN-01 | manual | OddContrast WCAG check | N/A | ⬜ pending |
| 01-02-01 | 02 | 1 | UI-DASH-01 | build | `npm run build` | N/A | ⬜ pending |
| 01-02-02 | 02 | 1 | UI-RESPONSIVE-01 | manual | Browser DevTools responsive | N/A | ⬜ pending |

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

---

## Wave 0 Requirements

- No test framework exists. This is acceptable for a UI-only overhaul where verification is primarily visual.
- The `build` command (`tsc -b && vite build`) serves as the primary automated validation: catches type errors, missing imports, and bundling failures.

*Existing infrastructure covers automated build validation. Visual verification is manual.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Color tokens pass WCAG 4.5:1 contrast | UI-DESIGN-01 | Visual/perceptual — requires external contrast tool | Use OddContrast with OKLCH values; verify each category color pair against white background |
| Summary card grid responds to viewport | UI-RESPONSIVE-01 | Layout behavior — requires browser viewport testing | Open DevTools, resize from 1440px to 768px, verify cards reflow |
| PageShell renders consistent header | UI-DESIGN-01 | Visual consistency — no automated assertion available | Navigate between pages, verify header pattern matches |
| StatCard variance badges render correctly | UI-DASH-01 | Visual — semantic colors and badge positioning | View dashboard with budget data, verify green/red badges on cards |

*All phase behaviors are primarily visual; automated validation is limited to build/type-check.*

## 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
