FA-50577 / Raster clipping / Member archive

Multisample clip resolve: parity any · case 02

Parity resolve behaves as any-sample coverage on even overlaps.

Member previewVariant 2 · 3 implementations · 11 checks per implementation

Case contract

Each command defines a pixel with a list of per-sample clip bits and an equally long integer weight list. Modes return any/all/parity/weighted majority. Invert precedes resolve; disabled samples do not participate. An empty enabled set never covers. Rotation permutes the bits before enabled lanes are selected.

Why this case matters

Raster clip state can leak coverage across draws even when every individual region is valid.

Sample boundary fixture

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