narration

The first target-matched, balanced candidate reaches 328.3 perplexity, a 31% reduction from random. Increasing the generic cleanliness weight worsened it to 331.1, so relevance is doing real work beyond merely preferring long clean pages. I’m checking a looser-filter variant now, then I’ll tune the register balance using exact tokenizer costs—especially important because code is more token-dense than prose.
