Width linking requires two finite endpoints including zero · case 03

Width linking requires two finite endpoints including zero is violated by the widget projection.

Member previewVariant 3 · 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: Width linking requires two finite endpoints 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.

Boundary fixture	Actual	Expected	Outcome
contract fixture 0	`{"link-enabled": false, "linked-lower": 0, "linked-upper": 2, "lower-clamp": -1, "reversal-warning": false, "upper-clamp": 0}`	`{"link-enabled": true, "linked-lower": 0, "linked-upper": 2, "lower-clamp": -1, "reversal-warning": false, "upper-clamp": 0}`	Failed
