How to Investigate AI Model Quality Changes After a Feature Definition Update

A feature definition change can alter model inputs even when the serving artifact is unchanged.

Checks to make

Version feature logic, compare distributions and null rates before and after, validate offline and online transformations, and segment performance by use case. Keep the prior feature definition available for controlled comparison or rollback.
