"""
Test script to demonstrate how Phase 1 enhancements fix the GitHub log agent hallucination issue.

The original issue: The GitHub log agent would hallucinate commit details when
analyzing log files, providing false information with high confidence.

The fix: Our enhanced BCE framework with context validation and prompt injection
detection prevents this by:
1. Detecting context inconsistencies
2. Validating information against previous responses
3. Preventing confidence inflation attacks
4. Implementing strict behavioral contracts for security contexts
