narration

The balanced deduplicated candidate improves dev perplexity from 382.185 to 381.855 under the frozen full training run. The gain is small but consistent with reduced token waste, so I’m retaining it and now doing the final validity and reproducibility checks.

It assigns each document to its strongest profile, adds\\n+language/structure hygiene rewards, penalizes boilerplate and corruption,\\n+removes duplicate crawl copies, and fair-merges ranked domain queues by text\\n+mass.

narration

Completed all deliverables:

  • selection.json: 36,000 unique valid IDs; verified to cover 12M tokens.
  • curate.py: reproducible balanced n-gram ranking, hygiene filtering, and deduplication.
  • claim.md: hypothesis, mechanism, falsification, and transfer.

Frozen dev evaluation: 381.855 perplexity.

#94
narration

The deliverables were already written successfully. I’ll confirm the remaining budget and exact final paths without rerunning the expensive curation.
