Moving a linked upper bound translates the lower bound by the same delta · case 02

Moving a linked upper bound translates the lower bound by the same delta is violated by the widget projection.

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: Moving a linked upper bound translates the lower bound by the same delta.

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.

Boundary fixture	Actual	Expected	Outcome
contract fixture 0	`{"link-enabled": false, "linked-lower": -1, "linked-upper": null, "lower-clamp": -1, "reversal-warning": false, "upper-clamp": -1}`	`{"link-enabled": false, "linked-lower": null, "linked-upper": null, "lower-clamp": -1, "reversal-warning": false, "upper-clamp": -1}`	Failed
