Primitive restart index separation · case 03

The restart sentinel is consumed as an ordinary vertex index.

Case contract

Split an index buffer into nonempty primitive runs at a configured restart sentinel. Restart markers are not vertices; consecutive markers produce no empty runs.

Why this case matters

A deterministic software graphics stage with explicit channel and coordinate conventions; no hardware, device profile or API behavior is inferred.

One recorded failure

Sample boundary fixture

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