Alerting on Drift

Day 78 of 100 Days of MLOps. Detecting drift is useless if nobody's told. Today you close the gap between a monitoring number and a human being paged: set a threshold on a drift signal, decide what's actually worth an alert, and fire a notification when the line is crossed. You'll build a check that stays silent on a healthy window and fires a detailed alert on a drifted one — the same threshold-to-notification pattern whether it runs in your code or in Prometheus Alertmanager. Runs 100% locally on any OS.
