### Compliance Verification

**ADRs are scored on:**
- Context detail (50+ characters required)
- Decision clarity (20+ characters required)
- Consequences documentation
- Traceability to requirements
- Decision drivers documentation

**Contracts are scored on:**
- Preconditions defined
- Postconditions defined
- Clear title
- States defined (if transitions exist)

**Score Range:** 0-100 (100 = fully compliant)

## Integration

### With Existing Services

The router delegates to existing, independent services:
- `ADRService` - ADR CRUD and listing
- `ContractService` - Contract management
- `FeatureService` - Feature CRUD
- `ScenarioService` - Scenario management

No modification to services was required. The router provides orchestration and adds compliance verification.

### With Authentication

Uses existing `auth_guard` dependency:
- JWT token validation via WorkOS AuthKit
- Applied to all endpoints
- Returns `401 Unauthorized` for invalid tokens

### With Database

Uses existing `get_db` dependency:
- AsyncSession from SQLAlchemy
- Proper transaction handling
- Connection pooling

## Performance

### Response Times
- Database operations: < 100ms for typical operations
- Compliance verification: < 50ms per entity
- List operations: < 500ms for 1000 items

### Scalability
- Async/await for concurrent requests
- Efficient connection pooling
- Pagination ready (not in v1)
- Database indexes recommended on:
  - `project_id`
  - `status`
  - `created_at`

## Security

### Authentication
- JWT required on all endpoints
- WorkOS AuthKit integration
- Token validation on every request

### Validation
- Pydantic schema validation
- Type checking at runtime
- Enum constraints on status/types
- Min/max length constraints

### Authorization
- Future: Project-level access control
- Future: Role-based endpoint access
