narration

Completed and validated:

  • selection.json: 108,690 unique valid IDs; covers exactly 12M packed tokens.
  • curate.py: reproducibly regenerates the evaluated selection.
  • claim.md: hypothesis, mechanism, falsification, and transfer.

Frozen-trainer dev perplexity: 296.94, improved from 311.03 before punctuation-format adaptation.

narration

The final deliverables were already written; I’m doing one last path and validity check rather than restarting any work.
