**TLDR:** An approach for managing changes in feature definitions as traceable versions over time.

<p>Feature versioning safely manages the evolution of the same feature under changing calculation logic over time. When a feature is corrected or a business rule changes, old training runs and new production usage must not be confused. This is highly valuable for reproducibility and model comparison. In multi-model enterprise AI infrastructures, feature version information is a critical governance element.</p>
