narration

The first controlled results are strong: random 476.7 PPL, prose-only 476.9, balanced density-ranked 328.7. That isolates the gain to register matching rather than superficial cleanliness. I’m adding a read-only diagnostic around the frozen trainer to see which target quarter remains weakest, then I’ll tune the token mix without changing training behavior.
