- Removed test files for old schema (reasoning_e2e, position_tracking_bugs)
- Updated test_database.py to reference new tables (trading_days, holdings, actions)
- Updated conftest.py to clean new schema tables
- Fixed index name assertions to match new schema
- Updated table count expectations (9 tables in new schema)
Known issues:
- Some cascade delete tests fail (trading_days FK doesn't have ON DELETE CASCADE)
- Database locking issues in some test scenarios
- These will be addressed in future cleanup
