It first ranks sufficiently\\n+long English documents while penalizing navigation, commerce/SEO phrases,\\n+URLs, repetition, fragments, and abnormal sentence statistics. It then makes\\n+a token-weighted register mixture (40% encyclopedic, 20% edited web, 20% news,\\n+20% technical Q&A), suppresses normalized exact duplicates, and defers text\\n+with more than 8% non-ASCII characters.\\n+\\n+An observable prediction independent of final perplexity is that the consumed\\n+prefix will contain substantially fewer navigation/privacy/cart phrases,\\n+non-English bytes, and normalized duplicates than a random 12M-token prefix.\\n+Its estimated register token shares should be close to 40/20/20/20.

narration

The final reproducible output now exactly matches the best measured candidate: 349.86 dev perplexity versus 448.22 random (about a 22% reduction). I’m doing the final validity pass on JSON uniqueness/range, script syntax, token coverage, and the claim document.

narration

Completed and validated:

  • selection.json: 104,993 unique valid IDs; fills 12M tokens.
  • curate.py: reproducible quality, domain-mixture, English, and deduplication pipeline.
  • claim.md: hypothesis, mechanism, falsification, and transfer.

Frozen dev evaluation: 349.86 perplexity, versus 448.22 for random selection—a 21.9% reduction.

The deliverables were already finalized before the interruption. I’ll verify the remaining budget and exact required paths without restarting any work.
