A deliberately altered online scale fails the release gate and the correct transform passes. This is evidence for a different corrective change: Add automated train-serving feature parity checks using a shared golden fixture set as a release gate. That other change addresses: A deployed model's online preprocessing changes independently from training transformations and silently alters numeric feature scaling.
