Case contract

An enum filter may retain a retired selected value but cannot add it again. Captions come from current labels with a stable-ID fallback. This example checks: Missing enum labels fall back to identity without replacing an explicit empty caption.

Why this case matters

Filter-widget state and serialization must preserve user constraints while the view changes.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
