narration

Completed and validated:

selection.json: 50,000 unique, valid IDs; packs exactly 12M tokens.
curate.py: reproducible target-similarity, quality, balance, and deduplication pipeline.
claim.md: required scientific claim sections.

Frozen dev perplexity: 307.758, versus 449.386 for random selection.

#197

narration

The deliverables were already finalized before the interruption. I’ll do one quick integrity check on the exact paths and preserve the validated selection unchanged.
