ThresholdTune: Operating-Point Calibration for Imbalanced Business Classifiers

A pre-deployment tool that sweeps decision thresholds on a trained credit-default or churn model, validates the best cutoff with bootstrap confidence intervals and noise tests, and locks in an operating point with a stability report — replacing the default 0.5 cutoff most teams ship with. It tells teams not just the best threshold, but how far it can drift before performance breaks.
