Developers dismiss about 40% of an automated reviewer's findings. The team tracks the dismissal rate but can't tell which prompt criteria or examples to change. What should they add first?

Answer: A — A detected_pattern field on each finding, to group dismissals by trigger

A detected_pattern field records which construct triggered each finding, so dismissals can be analyzed systematically and the noisy pattern's criteria or examples fixed. Confidence suppression (b) trims findings without explaining them. Free-text reasons (c) are inconsistent and hard to aggregate. A cap (d) hides findings without improving them.
