The standalone script reproduced the winning ranking byte-for-byte. Structural validation passes: 182,014 unique integer IDs, all in range, with a deep fallback. I’m doing the final tokenizer-level check now—exactly 12M tokens and byte identity with the array that achieved 356.68 dev PPL—then I’ll hand off the three deliverables.

The final deliverables are already valid and reproduce the 356.68 run exactly. With remaining experiment time, I’m checking two tightly scoped robustness questions before freezing: whether the sentence-overlap threshold should be 2/3/4, and whether demoting the small tail of very low-prose keyword pages helps. These do not change the core criterion or risk the verified fallback.
