We therefore build one *reference distribution per\nregister* from the disclosed dev target and select, for each register, the pool documents\nthat are most likely under it relative to the pool's own background -- then interleave the\nfour ranked lists so that any prefix of the submission (in particular the 12M-token prefix\nthe trainer consumes) is register-balanced.\n\n  1.
