# 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}
