Scorecard candidate attributes are the per-scorecard ratings an interviewer captured on each focus attribute — what they thought of this candidate on each attribute on this scorecard. Each row pairs one scorecard with one job_candidate_attribute (the per-job attribute being rated) and carries the rating in candidate_attribute_rating plus an optional free-text note. Filter by scorecard_ids to pull every attribute rating on a given scorecard, or by job_candidate_attribute_ids to see how interviewers rated the same attribute across scorecards (the read pattern used by talent-matching and partner interview-intelligence integrations). Sibling to /v3/scorecard_question_candidate_attributes, which maps questions to attributes on the interview kit rather than capturing interviewer ratings.
