# Phase 07 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | vitest 3.x |
| **Config file** | vitest.config.ts |
| **Quick run command** | `npx vitest run --reporter=verbose` |
| **Full suite command** | `npx vitest run --reporter=verbose` |
| **Estimated runtime** | ~5 seconds |

---

## Sampling Rate

- **After every task commit:** Run `npx vitest run --reporter=verbose`
- **After every plan wave:** Run `npx vitest run --reporter=verbose`
- **Before `/gsd-verify-work`:** Full suite must be green
- **Max feedback latency:** 5 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Threat Ref | Secure Behavior | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| 07-01-01 | 01 | 1 | VIZ-01 | — | N/A | unit | `npx vitest run` | ❌ W0 | ⬜ pending |
| 07-01-02 | 01 | 1 | VIZ-05 | — | N/A | unit | `npx vitest run` | ❌ W0 | ⬜ pending |
| 07-02-01 | 02 | 1 | VIZ-02 | — | N/A | unit | `npx vitest run` | ❌ W0 | ⬜ pending |
| 07-02-02 | 02 | 1 | TEST-01 | — | N/A | unit | `npx vitest run` | ❌ W0 | ⬜ pending |

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

---

## Wave 0 Requirements

*Existing infrastructure covers all phase requirements.*

Vitest is already installed and configured. Test files exist in `assets/test/`. No additional setup needed.

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Segmented control renders in card header | VIZ-01 | Visual layout in Kimai dashboard | Start dev Kimai, verify controls appear in widget header |
| Week-mode cells colored correctly | VIZ-02 | Visual regression check | Switch to week mode, verify 7 colored cells with correct labels |
| Mode switch preserves filter | SC-4 | Requires running Kimai with project data | Select a project filter, switch modes, verify filter state retained |

---

## 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 < 5s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
