"""
Tests for the contradiction detection system.
This test suite covers:
- ContradictionDetector initialization
- Statement checking against facts (with and without contradictions)
- NPC statement checking (with and without NPC tracker)
- Resolution suggestions for different severity levels
- Contradiction resolution
- Filtering unresolved contradictions
- Save/load persistence
