+
+**Add 22 integration tests for consent endpoints covering auth, ownership, CRUD, audit trail, idempotency, pagination, and admin access**
+
+## What Happened
+
+Created backend/tests/test_consent.py with 22 async integration tests organized into 9 categories: auth (401/403), ownership gating, happy-path PUT/GET, audit trail versioning, idempotency, partial updates, admin access, pagination, and 404 handling. Added 3 shared fixtures to conftest.py (creator_with_videos, creator_user_auth, admin_auth). All tests collect successfully with no import errors. Full execution requires the PostgreSQL test DB on ub01 (same constraint as all existing tests).
+
+## Verification
+
+Slice-level checks pass: model imports OK, migration file valid Python. Test collection: 22 tests collected, 0 errors. Full pytest execution blocked by test DB not being accessible locally (ConnectionRefusedError on localhost:5433) — same infrastructure constraint as all other test files.
+
+## Verification Evidence
+
+| # | Command | Exit Code | Verdict | Duration |
+|---|---------|-----------|---------|----------|
+| 1 | `cd backend && python -c "from models import VideoConsent, ConsentAuditLog, ConsentField; print('OK')"` | 0 | ✅ pass | 500ms |
+| 2 | `python -c "import importlib.util; spec = importlib.util.spec_from_file_location('m', 'alembic/versions/017_add_consent_tables.py'); ..."` | 0 | ✅ pass | 200ms |
+| 3 | `cd backend && python -m pytest tests/test_consent.py --collect-only` | 0 | ✅ pass | 1000ms |
+| 4 | `cd backend && python -c "import ast; ast.parse(open('tests/test_consent.py').read()); print('valid')"` | 0 | ✅ pass | 100ms |
+
+
+## Deviations
+
+Removed --timeout=60 flag (pytest-timeout not installed). Tests cannot run locally — requires ub01 PostgreSQL test DB.
+
+## Known Issues
+
+Tests need to be run on ub01 or inside Docker container with test DB access to get full pass/fail results.
