#283

narration

The standalone script reproduced the winning exploratory list byte-for-order: 170,263 unique, in-range IDs; the budget crosses after 12,514 documents at 12,000,518 pre-truncation tokens, with 178.9M tokens available overall. I’m doing the final frozen-pipeline run and artifact checks now.

final summary

Completed all deliverables:

selection.json: 170,263 unique IDs; 178.9M available tokens.
curate.py: deterministic, independently reproduced the selection.
claim.md: hypothesis, mechanism, falsification, and transfer.

Validation passed. Frozen dev perplexity: 296.587, versus 476.714 random baseline—a 37.8% reduction.
