We audited the full modeling pipeline and identified [actual issue, or describe the checks if none was found]. We repeated the evaluation with [all learned preprocessing\/feature selection] confined to the training partitions and used [independent-unit split]. The updated performance is [actual estimates and uncertainty], reported in [location]. We have replaced the previous figures and revised the interpretation accordingly.<\/p>\n<\/blockquote>\n
