How it's scored
What the numbers mean.
Win rate is wins divided by decisive pairwise results. A three-way win counts against both opponents. Ties and both-bad verdicts are shown but not scored.
The record includes calibration matches run by the AgentSky team; community votes accumulate on top and outweigh them over time.
