 ### Bugs Fixed
 
-- Fixed `deflection_rate` evaluator showing incorrect pass/fail labels in App Insights where all results were labeled "pass" regardless of the actual score. The inverse metric adjustment was overriding the evaluator's correct string labels, remapping every result to "pass".
+- Fixed `deflection_rate` evaluator showing incorrect pass/fail labels where all results were labeled "pass" regardless of the actual score. The inverse metric adjustment was overriding the evaluator's correct string labels, remapping every result to "pass".
 - Fixed `evaluate()` raising `EvaluationException: (InternalError) unhashable type: 'list'` when an evaluator emitted a list value under a `_result`-suffixed column. Binary aggregation now skips such columns with a warning instead of aborting the entire run.
 - Fixed row classification double-counting in `_calculate_aoai_evaluation_summary` where errored rows were counted separately and could also be counted as passed/failed. Rows are now classified into mutually exclusive buckets with priority: passed > failed > errored > skipped.
 - Fixed row classification where rows with empty or missing results lists were incorrectly counted as "passed" (the condition `passed_count == len(results) - error_count` evaluated `0 == 0` as True).
