Exclusion uses a negative rather than selected badge is violated by the widget projection.

Member previewVariant 4 · 3 implementations · 10 checks per implementation

Case contract

A facet has neutral/include/exclude states. The UI cycles neutral to include to exclude to neutral, exposes polarity, and serializes inclusion and exclusion separately. This example checks: Exclusion uses a negative rather than selected badge.

Why this case matters

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