"""
Comprehensive coverage tests for SQLiteMemoryDatabase.
This module specifically targets uncovered lines to push overall coverage above 80%.
Tests focus on:
- Error handling paths
- Edge cases in search (fuzzy matching, multi-term, pagination)
- Advanced relationship features (temporal queries, history, context search)
- Statistics and activity tracking
- Utility methods and helper functions
