# Phase 19 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | bun test |
| **Config file** | none — built-in to Bun |
| **Quick run command** | `bun test` |
| **Full suite command** | `bun test` |
| **Estimated runtime** | ~5 seconds |

---

## Sampling Rate

- **After every task commit:** Run `bun test`
- **After every plan wave:** Run `bun test`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 5 seconds

## Per-Task Verification Map

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

---

## Wave 0 Requirements

*Existing infrastructure covers all phase requirements — test helper `createTestDb()` needs schema updates for new tables.*

---

## Manual-Only Verifications

*All phase behaviors have automated verification.*

---

## 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
