The evaluator commit predates this private Hub publication, so its --dataset-info output still records the former distribution block. The immutable URL above supersedes only that distribution status; scoring semantics are unchanged.

Prediction CSV must contain exactly id1,id2,predict, use the panel's exact row order, contain no duplicate/null/non-finite values, and retain integer IDs.
The primary scalar applies the official category-wise unweighted sklearn.average_precision_score semantics to a row-level two-shift prior model. Fractional LLM votes are explicitly downweighted. Tie handling matches sklearn exactly.
Applicability boundary
This is retrospective_only evidence. It reproduced the ordering of five historical submissions with MAE 0.0015250420378983165 and maximum absolute error 0.002407512449966648, but it has no prospective validation and does not identify hidden Public truth. Use it as transfer evidence beside component-disjoint human OOF, never as a standalone promotion gate.
The panel and historical outputs are derived from private competition data and remain private team assets.
