Telecom churn – reproducibility package (code, calibrated scores, models, figures)

This record provides code and artifacts to reproduce the manuscript’s results. It includes source code (training/evaluation, post-hoc XAI), calibrated out-of-fold/test scores, cross-validation summaries, trained models, and all figures. No resampling is applied (class imbalance handled via class_weight="balanced"); PR-AUC is the primary selection metric; probabilities are isotonic-calibrated for decision-grade risk tiering. Raw IBM Telco Customer Churn data are not redistributed; obtain from Kaggle (dataset: blastchar/telco-customer-churn, file WA_Fn-UseC_-Telco-Customer-Churn.csv)
