Problem

Our automated data-quality suite writes one row per check it runs, and we need to see where records are breaking. For each table that has failing checks, report how many checks failed and how many of those were critical or high severity, most failures first.

Summary

Every dataset has a weak point. Surface the ones the checks already caught.
