Brush upper bounds clamp to the domain after drag normalization · case 05

Brush upper bounds clamp to the domain after drag normalization is violated by the widget projection.

Member previewVariant 5 · 3 implementations · 10 checks per implementation

Case contract

A histogram brush selects intersecting bucket identities over a half-open horizontal interval; clicks without width do not create a range and the final brush converts to domain edges. This example checks: Brush upper bounds clamp to the domain after drag normalization.

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.
