+# Phase 1 Plan 02: Wave 0 Test Scaffolds — Summary
+
+**One-liner:** Async SQLAlchemy + httpx fixtures added to conftest; 19 xfail Wave 0 tests across 5 files scaffold Plan 03-05 contracts before implementation.
+
+## What Was Built
+
+This plan authored all Wave 0 test scaffolds identified in `01-VALIDATION.md` before any implementation lands. Every test that depends on Plan 03-05 code is marked `xfail(strict=False)` so the suite stays green between waves. Later executors remove the xfail markers as their code lands.
+
+### Files Created
+
+| File | Purpose | Tests |
+|------|---------|-------|
+| `backend/tests/test_storage.py` | Wave 0 STORE-02 unit tests | 6 xfail tests |
+| `backend/tests/test_alembic.py` | Wave 0 migration integration tests | 2 xfail tests |
+
+### Files Modified

+|------|--------|-------------|

+### Test Functions Added

+- `test_object_key_schema` — regex `^[^/]+/[^/]+/{uuid4}(\.ext)?$` against `put_object` return value
+- `test_filename_not_in_object_key` — asserts "invoice", "Q3", "secret" not in key
+- `test_storage_backend_abc_methods` — incomplete subclass raises `TypeError`
+- `test_get_storage_backend_returns_minio` — factory returns `MinIOBackend`
+- `test_put_object_uses_asyncio_to_thread` — `asyncio.to_thread` was called with `_client.put_object`

+
+**test_alembic.py** (all xfail → Plan 03):
+- `test_migration_creates_all_tables` — all 11 v1 tables: users, quotas, refresh_tokens, folders, documents, topics, document_topics, shares, audit_log, cloud_connections, groups
+- `test_documents_user_id_nullable` — `PRAGMA table_info(documents)` confirms `notnull=0`
+
+**test_health.py** (1 xfail → Plan 05):
+- `test_health_checks_postgres_and_minio` — asserts `checks.postgres == "ok"` and `checks.minio == "ok"`

+## Commits
+
+| Hash | Message |
+|------|---------|
+| `1f675fc` | feat(01-02): add async db_session and async_client fixtures to conftest.py |
+| `27fa0d4` | test(01-02): add Wave 0 scaffolds test_storage.py and test_alembic.py |
+| `d856a2e` | test(01-02): extend test_health.py and port test_documents.py to async client |
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+The `async_client` fixture was named `async_client` (not `client`) as specified in the plan action to avoid collision with the legacy sync `client` fixture. This matches the plan's intent.
+
+## Known Stubs
+
+None. All test files reference not-yet-existing modules inside `try/except ImportError: pytest.skip()` blocks — this is intentional Wave 0 scaffold behavior, not stubs.
+
+## Threat Flags
+
+None. All test data is synthetic (no real PII). aiosqlite DB lives in `tmp_path` and `:memory:` only (T-01-02-01 mitigated). No new network endpoints introduced.
