 "creator": "Sharks, Lee",
 "date": "2026-08-15",
 "description": "Specifies a drift operator computed only over matched pairs — same address, same surface, two dates — and refuses two tempting alternatives on stated grounds: regression on source count is sign-ambiguous, and field-mean-by-date measures the sampler rather than the field. Pre-registers a trial before the treated domains go live, with treated, archive-control and field-control arms and difference-in-differences required for attribution. Records a retrospective prior explicitly as NOT-evidence, with five reasons it fails to be a finding.",
