Unknown count options follow all known counts including zero · case 03

Unknown count options follow all known counts including zero is violated by the widget projection.

Member previewVariant 3 · 3 implementations · 10 checks per implementation

Case contract

Facet ordering uses pinned then selected priority, descending known counts, and stable server order for ties; unknown counts sort behind known counts. This example checks: Unknown count options follow all known counts including zero.

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.
