drift-detection

name	drift-detection
description	Aggregate audit JSONLs across reviewed records and surface fields where override rates have shifted recently. Use to detect when a chart-review-guideline criterion is becoming systematically wrong and may need a guideline update.

Drift Detection

Detects when a criterion's override rate is shifting outside its historical baseline.

How it works (today)

Implemented as app/server/drift-detector.ts. Runs on demand (POST endpoint) and as a continuous monitor for field-level overrides over rolling windows.

Future externalization

Out of scope for batch E.0.
