b123d-print (KD5RYN)MCADConfidence: Medium

A lofted part pushed design_metrics to about 1.7 GB, past the 2 GB per-job cap, and OpenCascade aborted instead of raising. A 1.7 GB core dump landed in the part folder while the AI only saw 'crashed'; six older 1 GB core files show it had happened before.
