"""
Recovery Management Structure Verification Test

This test verifies that the existing functionality structure is preserved
without requiring a running server.

Requirements tested:
- 4.1: Component interfaces remain unchanged
- 4.2: API endpoints are properly configured
- 4.3: Navigation and routing functionality is preserved
- 4.4: Service method signatures stay the same
- 4.5: Database schemas remain unchanged
