Devices currently contributing. sigma is each island's annealed mutation step - low means it is refining, high means still exploring. curriculum is its training difficulty level; a median drop right after a level bump is expected, not a regression.

champion lineage
Every champion that won its duel, newest first. record is the number it won on: the duel-verified score, with the score the beaten champion made on those same episodes in its tooltip - that column only ever moves up. batch score is a separate fresh batch measured afterwards, so it is NOT comparable between rows and a later champion can read lower. moving is the behaviour column that matters: a cat at 0% is camping, and kills alone cannot tell the difference.

human demos · queued for training
Runs a human played that beat the model on its own fitness terms. Evolution has no gradient, so a demo is not training data in the usual sense: it becomes an alternative fitness - match the human's action on the same frame - and the genome fitted to it competes from a tail slot like any other, never as a protected champion. match is how much of the run that genome reproduces; it has to beat the baseline an always-same-action net would score, or nothing is planted at all.
