narration

The Bayes router now produces visibly correct news and technical pages, but its dev score regressed to 452.9. The cause is in packing, not routing: one-document round-robin is not token-balanced because news/Q&A documents are much shorter than encyclopedia/general pages. I’m changing the priority merge to deficit scheduling by cumulative characters, so every cutoff—not just the full surplus—has approximately equal register mass.
