narration

Per-quarter diagnostics show the current bottleneck is Wikipedia formatting (PPL ~769), while the technical quarter responds strongly to matched data. A 2.5M/2.5M/3M/4M mix improves aggregate dev PPL to 324.1; pushing technical data further degrades quality. I’m making one final ranking refinement based on GPT-2 token n-grams, which can capture punctuation, wiki markup, and HTML patterns that the word model misses.
