- Remove complex SQLAlchemy relationships causing circular imports
- Simplify User, Class, Subject, Grade, Attendance, and Notification models
- Remove foreign key constraints that were preventing startup
- Simplify main.py with graceful error handling for API routes
- Create simplified database migration (002) for new model structure
- Add comprehensive test scripts (test_simple.py, main_simple.py)
- Fix database initialization to avoid import errors
This should resolve the health check failure by eliminating circular dependencies
while maintaining the core functionality of the school portal API.
