print("⚠️ **Common Conflict Types:**")
print("   - **Missing in docs**: Undocumented features in code")
print("   - **Missing in code**: Documented but not implemented")
print("   - **Signature mismatch**: Different parameters/types")
print("   - **Description mismatch**: Different explanations")
print()

print("🎯 **Value:**")
print("   - Identifies documentation gaps")
print("   - Catches outdated documentation")
print("   - Highlights implementation differences")
print("   - Creates single source of truth showing reality")
