# Phase {N} — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | {pytest 7.x / jest 29.x / vitest / go test / other} |
| **Config file** | {path or "none — Wave 0 installs"} |
| **Quick run command** | `{quick command}` |
| **Full suite command** | `{full command}` |
| **Estimated runtime** | ~{N} seconds |

---

## Sampling Rate

- **After every task commit:** Run `{quick run command}`
- **After every plan wave:** Run `{full suite command}`
- **Before `/gsd-verify-work`:** Full suite must be green
- **Max feedback latency:** {N} seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| {N}-01-01 | 01 | 1 | REQ-{XX} | unit | `{command}` | ✅ / ❌ W0 | ⬜ pending |

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

---

## Wave 0 Requirements

- [ ] `{tests/test_file.py}` — stubs for REQ-{XX}
- [ ] `{tests/conftest.py}` — shared fixtures
- [ ] `{framework install}` — if no framework detected

*If none: "Existing infrastructure covers all phase requirements."*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| {behavior} | REQ-{XX} | {reason} | {steps} |

*If none: "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 < {N}s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** {pending / approved YYYY-MM-DD}
