Last-page navigation stops one page early.

Member previewVariant 5 · 3 implementations · 14 checks per implementation

Case contract

Empty pagination uses page zero with disabled controls; nonempty page clamps to 1..pages; actions move by one or to endpoints; availability reflects resulting page.

Why this case matters

A deterministic model of pagination button state; this isolates one interface invariant without requiring a browser.

One recorded failure
