Change Monitoring Systems

1. File-Level Monitoring

def monitor_file_changes():
    """Track individual file modifications"""
    changes = {
        "timestamp": datetime.now().isoformat(),
        "files_modified": [],

        "files_deleted": [],
        "significance_score": 0.0,
        "categories": []
    }

    # Monitor file system changes
    for file_path in get_modified_files():
        change = {
            "path": file_path,
            "type": "modified",
            "size_delta": calculate_size_change(file_path),

if issues:
    display_compliance_alerts(issues)
else:
    display_compliance_status("compliant")
