Lower-bound crossing is clamped only under range lock · case 02

Lower-bound crossing is clamped only under range lock is violated by the widget projection.

Member previewVariant 2 · 3 implementations · 10 checks per implementation

Case contract

Editing one numeric endpoint clamps only when the range lock is enabled; linked-width edits translate the opposite endpoint, and unbounded sides remain unbounded. This example checks: Lower-bound crossing is clamped only under range lock.

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.
