Development Task

Research direction

Start by locating the audit-log handling and any existing SQL digest aggregation or comparison entry points in the repository. Clarify how two clusters are selected and how execution time and affected rows should be grouped and compared. Done means the requested comparison can identify differences by SQL digest and expose both metrics.
