ROOT CAUSE

Lane enable indices are confused with Boolean coverage values.

THE FAILURE

Lane enable indices are confused with Boolean coverage values.

Unsuccessful approach: Replacing membership with a maximum enabled lane assumes the enabled mask has no holes.

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.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 11 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

Finite one-dimensional integer sample sets model coverage state only; no geometric intersection, memory layout, GPU or graphics-standard conformance is claimed. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.

Observations recorded using Python 3.12.14 at 2026-09-29T14:45:10.557733+00:00.
