Reciprocal Rank@k is defined as the reciprocal of the rank of the first relevant result: ranking first gives 1 point, ranking third gives 1/3 point, and having none at all gives 0 points.
Neither Recall@k nor Reciprocal Rank@k measures whether the final answer is correct, safe, or grounded; both only answer questions at the retrieval level.
