narration

Completed and validated:

selection.json: 35,000 unique valid IDs; covers 12M tokens.
curate.py: reproducible quality-gating, diversity, and domain-balancing selector.
claim.md: hypothesis, mechanism, falsification, and transfer.

Dev perplexity: 446.01, versus 476.01 for seeded random selection—a 6.3% improvement.
