# T02: Added consent API router with 5 endpoints (list, get, upsert with audit trail, history, admin summary) and Pydantic schemas, wired into main.py

**Added consent API router with 5 endpoints (list, get, upsert with audit trail, history, admin summary) and Pydantic schemas, wired into main.py**

## What Happened

Built the consent API layer on top of T01 models. Added 5 Pydantic schemas to schemas.py, created routers/consent.py with ownership verification helper (admin bypass), 5 endpoints covering CRUD + audit history + admin summary, and registered in main.py. PUT endpoint upserts consent with per-field audit log entries using auto-incrementing versions.

## Verification

Ran task verification: `from routers.consent import router` → 5 routes OK. Ran both slice-level checks: model imports OK, migration file valid Python.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd backend && python -c "from routers.consent import router; print(f'{len(router.routes)} routes OK')"` | 0 | ✅ pass | 500ms |
| 2 | `cd backend && python -c "from models import VideoConsent, ConsentAuditLog, ConsentField; print('OK')"` | 0 | ✅ pass | 500ms |
| 3 | `python -c "import importlib.util; spec = importlib.util.spec_from_file_location('m', 'alembic/versions/017_add_consent_tables.py'); ..."` | 0 | ✅ pass | 300ms |
