Split-pane divider allocation: Compressed panes ignore their relative minimum sizes · case 03

Compressed panes ignore their relative minimum sizes.

Member previewVariant 3 · 3 implementations · 10 checks per implementation

Case contract

Subtract divider from total; honor both minimums when feasible; otherwise share available width in proportion to minima; panes sum to available space.

Why this case matters

A deterministic model of split-pane divider allocation; this isolates one interface invariant without requiring a browser.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
