Case contract

A filter-builder drag moves a criterion between explicit group identities, rejects descendant cycles, and retains operator grouping when flattening is unsafe. This example checks: Reparenting removes the specific dragged criterion from its source.

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.
