narration

The ablations are decisive: equal domain balancing scores 313.6, quality-only 384.1, and a 35% technical mix 325.1. I’m keeping the equal 25% mix, which is both best on dev and most aligned with the disclosed hidden-target composition. Next I’m tightening the documentation and running validity/reproducibility checks.

It combines bounded\\n+target log odds with explicit extraction-noise penalties, removes normalized-prefix\\n+duplicates, ranks within inferred register, and uses token-deficit scheduling to\\n+keep every prefix near a 25/25/25/25 mixture.\\n+\\n+An observable prediction independent of final perplexity is that selected text\\n+will have substantially fewer short fragments, repeated navigation lines, cookie/\\n+login/cart boilerplate, and exact mirrored pages than a random selection. The\\n+estimated token totals of the four inferred registers should each be within 1% of\\n+one quarter at the 12M-token cutoff.\\n+\\n+# Falsification\\n+\\n+The hypothesis is falsified if a seeded random selection, a quality-only ranking,\\n+or an unbalanced register mixture consistently beats the balanced selection on\\n+disjoint target samples. It is also falsified mechanistically if a manual blinded\\n+audit does not find reduced boilerplate/duplication, or if exact packing shows a\\n+material register imbalance.
