Case contract

A range editor stores separate lower and upper inclusivity, suppresses brackets for open endpoints, and identifies empty point intervals. This example checks: Point intervals require both endpoints to include the point.

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.
