narration

Adding Wikipedia capacity did not help: 25% and 28% Wikipedia both landed around 317.3–317.4, versus 315.7 with equal 23% shares for the three prose registers. The allocation curve points to roughly 30% Q&A as the local optimum, so I’m doing one final allocation check there before freezing the criterion.

narration

The final allocation check favored 31% Q&A; 30% unexpectedly regressed to 320.86, so I’m freezing the observed best at 315.73 rather than overfitting more runs. I’m now turning the experimental scorer into a clean standalone curate.py, regenerating the selection from raw inputs, and validating token coverage, uniqueness, and reproducibility.

The standalone regeneration is in its full-corpus scoring pass now. It intentionally uses only pool.jsonl, multi_dev.npy, and the cached GPT-2 tokenizer—no candidate cache or embedded IDs—so the resulting selection.json directly demonstrates reproducibility.
