narration

The quarter diagnostic is decisive: encyclopedia is the bottleneck (PPL 766), while technical Q&A is already much easier (147); web and news are 267/288. Equal target evaluation does not imply equal training allocation when domains differ this much in entropy and match quality. I’m reallocating the same 12M tokens toward encyclopedia (6M) and away from Q&A (1.5M), with 2.5M web and 2M news, then validating the tradeoff end to end.

narration

The aggressive 6M encyclopedia allocation regressed to 308.64, so the issue is selection diversity/quality rather than raw quota. I’m reverting to equal token coverage and testing a generic topic-saturation rule: repeated proper-name subjects are capped per domain, preventing dozens of near-topic documents (such as one political figure) from crowding out breadth without using any hand-picked IDs.
