 ### Bugs Fixed
 
 - 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 `task_adherence` red team scoring by adding `scenario=redteam` to the RAI scorer evaluation payload, ensuring the server-side score mapping correctly routes to Direct mapping for attack success determination.
 - 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).
 - Fixed `_get_metric_result` prefix matching where shorter metric names (e.g., `xpia`) could match before longer, more-specific ones (e.g., `xpia_manipulated_content`). Now sorts by length descending for correct longest-prefix matching.
