narration

The first candidate scores 351.3 dev perplexity versus 476.7 for the fixed-seed random baseline—a large, credible gain. The stronger-clean-source variant is now ready, so I’m testing whether removing more late-corpus boilerplate preserves enough genuine technical material.

narration

The stronger late-corpus penalty regressed to 386.2, so the late material contains valuable technical/Q&A signal despite its noisier extraction. I’m retaining the first candidate and running one diagnostic retrain that reports each target quarter separately; that will tell me whether the next adjustment should be domain mix or within-domain quality.
