## What's Ready for Implementation

### API Endpoints (20+ routes needed)

**Signage Management:**
- POST `/api/v1/signage/displays` - Register device
- POST `/api/v1/signage/messages` - Create alert
- GET `/api/v1/signage/active` - Current displays
- PATCH `/api/v1/signage/{id}/status` - Update device status

**Exam Proctoring:**
- POST `/api/v1/exams/sessions` - Start exam
- GET `/api/v1/exams/active-sessions` - Active exams
- POST `/api/v1/exams/{id}/events` - Log event
- PATCH `/api/v1/exams/{id}/submit` - Submit exam
- GET `/api/v1/exams/{id}/security-report` - Security analysis

**Notifications:**
- GET `/api/v1/notifications/hub` - Get unread
- PATCH `/api/v1/notifications/{id}/read` - Mark read
- PATCH `/api/v1/notifications/{id}/archive` - Archive
- POST `/api/v1/notifications/batch` - Create bulk

All endpoints follow middleware pattern and include:
- Authentication validation
- Role-based authorization
- Audit logging
- Input validation
- Error handling
- Standardized responses
