# Phase 1 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | pytest 8.x |
| **Config file** | none — Wave 0 installs |
| **Quick run command** | `pytest tests/ -x -q` |
| **Full suite command** | `pytest tests/ -v` |
| **Estimated runtime** | ~5 seconds |

---

## Sampling Rate

- **After every task commit:** Run `pytest tests/ -x -q`
- **After every plan wave:** Run `pytest tests/ -v`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 10 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 01-01-01 | 01 | 1 | INFRA-01 | smoke | `pytest tests/test_health.py -x` | ❌ W0 | ⬜ pending |
| 01-01-02 | 01 | 1 | INFRA-02 | unit | `pytest tests/test_static.py::test_no_cdn_urls -x` | ❌ W0 | ⬜ pending |
| 01-02-01 | 02 | 1 | INFRA-01 | unit | `pytest tests/test_db.py::test_create_tables -x` | ❌ W0 | ⬜ pending |
| 01-03-01 | 03 | 1 | INFRA-02 | unit | `pytest tests/test_intunewin.py::test_byte_layout -x` | ❌ W0 | ⬜ pending |
| 01-03-02 | 03 | 1 | (spike) | manual | Upload to real Intune tenant | N/A | ⬜ pending |

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

## Wave 0 Requirements

- [ ] `tests/__init__.py` — package marker
- [ ] `tests/conftest.py` — shared fixtures (temp dir, test DB path)
- [ ] `tests/test_health.py` — covers INFRA-01 HTTP health check
- [ ] `tests/test_db.py` — covers INFRA-01 schema init (all tables created, WAL mode)
- [ ] `tests/test_static.py` — covers INFRA-02 no-CDN-URLs assertion
- [ ] `tests/test_intunewin.py` — covers spike byte layout validation
- [ ] Framework install: `pip install pytest httpx` — add to `requirements-dev.txt`

*Existing infrastructure covers: None (greenfield project)*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| No Node.js in container | INFRA-02 | Requires running container inspection | `docker exec imptune which node` — should return nothing |
| .intunewin uploads to real Intune | (spike) | Requires Intune tenant access | Upload generated .intunewin via Intune portal, verify "successfully uploaded" status |

---

## 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 < 10s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
