What this does not establish
Self-selected Anthropic staff, small closed market, correlated runs and first-party study; no external marketplace ROI inference.

What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
