%description
Provides utilities to detect common data leakage patterns including
train/test contamination, temporal leakage, and data duplication,
enhancing model reliability and reproducibility in machine learning
workflows. Generates diagnostic reports and visual summaries to support
data validation. Methods based on best practices from Hastie, Tibshirani,
and Friedman (2009, ISBN:978-0387848570).
