Designs a production drift-monitoring plan for ML systems - statistical tests per feature type, PSI and KS alert thresholds, monitoring cadence, and evidence-based retraining triggers - including a runnable PSI calculator. Use when someone asks "how do I know if my model is drifting", "set up drift monitoring for this model", "should we retrain", or is investigating unexplained model performance d
