# Phase 1 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | pytest 7.x (asyncio_mode = auto) |
| **Config file** | `backend/pytest.ini` |
| **Quick run command** | `cd backend && pytest tests/test_health.py -v` |
| **Full suite command** | `cd backend && pytest -v` |
| **Estimated runtime** | ~30 seconds |

---

## Sampling Rate

- **After every task commit:** Run `cd backend && pytest tests/test_health.py -v`
- **After every plan wave:** Run `cd backend && pytest -v`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 30 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Threat Ref | Secure Behavior | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| 1-01-01 | 01 | 1 | STORE-01 | — | N/A | unit | `cd backend && pytest tests/test_health.py -v` | ❌ W0 | ⬜ pending |
| 1-01-02 | 01 | 1 | STORE-01 | — | MinIO key never contains human filename | unit | `cd backend && pytest tests/test_storage.py::test_object_key_format -v` | ❌ W0 | ⬜ pending |
| 1-02-01 | 02 | 1 | STORE-01 | — | N/A | unit | `cd backend && pytest tests/test_alembic.py -v` | ❌ W0 | ⬜ pending |
| 1-02-02 | 02 | 1 | STORE-02 | — | Object key is UUID-based, not filename | unit | `cd backend && pytest tests/test_storage.py::test_minio_key_schema -v` | ❌ W0 | ⬜ pending |
| 1-03-01 | 03 | 2 | STORE-07 | — | No file locks; multiple workers can run | integration | `cd backend && pytest tests/test_documents.py -v` | ❌ W0 | ⬜ pending |
| 1-03-02 | 03 | 2 | STORE-01 | — | End-to-end upload works with new storage layer | integration | `cd backend && pytest tests/test_documents.py::test_upload_end_to_end -v` | ❌ W0 | ⬜ pending |

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

## Wave 0 Requirements

- [ ] `tests/test_health.py` — rewrite to probe PostgreSQL + MinIO endpoints (not just `{"status": "ok"}`)
- [ ] `tests/test_storage.py` — new file: unit tests for `StorageBackend` ABC, MinIO key schema (STORE-02), and object CRUD
- [ ] `tests/test_alembic.py` — new file: verify migration applies cleanly, all tables exist, columns match schema
- [ ] `tests/test_documents.py` — rewrite to use PostgreSQL + MinIO storage layer (existing tests are coupled to flat-file storage)
- [ ] `tests/conftest.py` — add async SQLAlchemy test engine fixture (in-memory SQLite for unit tests, real PostgreSQL for integration)

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| `docker compose up` starts all services cleanly | STORE-01 | Requires Docker daemon | Run `docker compose up --build` and confirm all health checks pass in the `docker ps` output |
| `alembic upgrade head` completes with no errors | STORE-01 | Requires live PostgreSQL | Run `cd backend && alembic upgrade head` against the Docker PostgreSQL instance; confirm zero errors and all tables created |
| Celery worker starts and processes a task | STORE-07 | Requires running Redis + worker | Trigger a document upload; confirm extraction + classification completes via Celery (check worker logs) |
| Existing document upload workflow works end-to-end | STORE-01 | Full integration | Upload a PDF through the UI; confirm it appears in the document list with extracted text and AI classification |

---

## 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 < 30s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
