Class is research_demo because the researcher intentionally published an empty, benign package. impact_realized is true only in the narrow sense that real third parties downloaded it and company repositories used or recommended it; no malware payload or downstream loss is claimed. Later malicious evolution of the technique is recorded separately. AI Incident Database incident 731.",
