## What the story says

Regal uses CodeRabbit as the first automated reviewer on every pull request, including AI-generated ones from non-technical contributors, so authors get feedback before engineers review. It also uses Change Stack walkthroughs, PR summaries and diagrams, and a custom rule that flags database-migration risks.
