"""Edge case tests for WHERE clause filtering on hybrid tables (Issue #124).

This test suite covers advanced edge cases beyond the basic regression tests:
- Complex nested conditions with mixed AND/OR logic
- NULL value handling in FK relationships
- Multiple FK relationships on the same table
- Empty result sets with various operators
- Array operators on hybrid tables
- Deep nesting (3+ levels)
- Performance edge cases with large datasets
