Five pillars, four colored point lights; closest-hit emits one shadow ray per light from the same invocation (raysPerPixel = 4, maxDepth = 2), so up to four rays per pixel rtAccumulate in a single SHADE pass — the contention case #30 exists for. Each pillar casts four separable colored shadows; an accumulator race or capacity drop shows as flickering dark noise or a missing shadow color. Two frames a second apart diff at 2 px / 1.85 M (last-ulp CAS ordering), confirming no lost updates. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
