How to read. Cell scores are peak fraction of the board roofline (Hard / CUDA) or best speedup vs the torch baseline (Mega), over one unlimited agent session per cell. Audit chips come from the human/subagent reward-hack review of every published cell; scores from flagged sessions render dimmed — they don't count toward the charts.

Board summary bars are each score relative to the best published model on that board (1.00 = board leader); the printed number is the bench-native score.

Methodology. Rank per bench: valid passes (audited-clean correct cells / problems) desc, then mean normalized performance over the FULL problem deck (cell score / board best per problem; fail/invalid/missing cells count as 0) desc. Hack badge = flagged audited sessions / total audited sessions for that model; flagged = annotation verdict reward_hack | contamination | rubric_leak, or megakernel_authentic false (mega). Verdicts come from per-run audit YAMLs, not static lint. Hack rate is displayed, never a sort key. Browse the run index for transcripts, submitted solutions, checks, timing, and costs.
