Remove 82 redundant PMLB copies; the 267 retained records exactly match the corrected UCI train/test union. Pool that cohort for benchmark CV rather than using the UCI 80/187 split. Use five stratified outer folds and three inner folds; fit imputation, encoding and scaling within training partitions.",
