Closing the Loop: Monitoring-Triggered Retraining

Day 79 of 100 Days of MLOps. You can detect drift and get alerted — but a human still clicks 'retrain.' Today you remove the human: wire drift detection straight into the automated retraining pipeline, so when drift crosses the threshold, a retrain fires by itself. You'll watch a self-healing loop skip a healthy window and, on a drifted one, automatically retrain a broken model — dropping its error from $445,234 back to $12,131 with nobody in the loop. This is the model that watches itself and fixes itself. Runs 100% locally on any OS.
