narration

The last ablations confirm that the noisier partition cannot simply be excluded—it contains much of the useful technical material—and length bias also hurts. I’ve frozen the best rule: normalized target-vs-web unigram/bigram log-odds, an independent prose/boilerplate score, exact deduplication, and a 50/16.66/16.67/16.67 token-mass schedule. Its dev perplexity is 317.0 versus 476.7 random.

Weighted fair scheduling prevents the\\n+easiest class from consuming the prefix, while exact normalized deduplication\\n+spends each token once.
