Documents should be preferred when their smoothed word distribution resembles the disclosed equal-weight, four-register target, but target affinity must be constrained by the pool's monotone assembly-quality rank so that topical keyword matches cannot promote spam and boilerplate from the tail.\\n+\\n+# Mechanism\\n+\\n+`curate.py` estimates clipped word log-odds between `multi_dev.npy` and the clean candidate region of the pool. A document's mean log-odds is combined with its assembly rank; rare target words are ignored, all word contributions are clipped, and unseen words receive a small penalty. The observable prediction, independent of final perplexity, is that the consumed slice has higher mean target-vs-web word log-odds than raw ID order while remaining concentrated in the early quality region. It should also have fewer navigation/storefront pages than a target-affinity-only ranking.\\n+\\n+# Falsification\\n+\\n+Hold the tokenizer, model, token budget, seed, and training recipe fixed. Compare raw ID order, rank-only selection, affinity-only selection, and the combined rank. The hypothesis is falsified if the combined selection does not improve held-out cross-entropy on fresh samples from each of Wikipedia, high-quality web prose, news, and technical Q&A, or if gains come from one register while materially harming another. As a data-only check, it is also falsified if the selected slice fails to increase held-out target word log-likelihood relative to raw order.\\n+\\n+# Transfer\\n+\\n+The method transfers to another web pool by replacing the target sample, re-estimating target/background counts, and recalibrating the rank scale on that pool's quality ordering. The smoothing, minimum-count threshold, clipping, and rank regularization are specifically intended to transfer: they use register-level distributional evidence rather than hand-picked IDs, domains, URLs, or exact phrases. If a new pool has no meaningful assembly-quality order, the rank prior should be replaced with an independently measured prose-quality score.\\n*** End Patch\";\ntext(await tools.apply_patch(patch));\n"

narration

The close-neighbor check confirms a real local optimum: 2.35 scores 425.87, 2.40 scores 422.47, and 2.45 regresses to 435.07. The final script reproduces the 2.40 ordering exactly. I’m doing one last narrow check below 2.40, then final validation; the current 2.40 selection remains the incumbent.
