How Data Leaks Inflate Results and Mislead Your Models

A car price model that scored twelve R-squared points higher than it should have wasn't a breakthrough; it was a leak. A preprocessing pipeline let the model peek at the test set before the exam, and the inflated results masked a deeper problem. That kind of shortcut doesn't just distort one metric, it erodes trust in the entire evaluation. It's a sharp reminder that data hygiene is part of model integrity, not a side note.
