 #### 6.4 Command-line Report Generation Tool
 
-This tool bypasses the execution phase of all three analysis engines, directly loads their most recent log files, and generates a consolidated report without requiring the Web interface (while also skipping incremental file-validation steps). It is typically used when rapid retries are needed due to unsatisfactory report outputs, or when debugging the Report Engine.

It will also generate a Markdown copy after the PDF by default (toggle via CLI flag).
