Split-pane divider allocation: Impossible minimum constraints overflow a narrow container · case 02

Impossible minimum constraints overflow a narrow container.

Member previewVariant 2 · 3 implementations · 9 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.

Boundary fixture	Actual	Expected	Outcome
narrow	`[20, 10]`	`[10, 20]`	Failed
