No dates of occurrence or disclosure are stated (the article is dated 2026-03-20 but that is the source date, so no event date was entered). The count of seven affected individuals is an NRC allegation as reported, not a confirmed finding. No autonomous agent is described, so agent_involved, failure_class and trigger were left out. No adversarial actor is stated, so adversarial_actor was left out. The system is treated as a generative AI tool used by a person, so responsible_party is deployer and the root cause oversight is taken from the journalist's own statement. Control I7 is marked missing from the statement that quotes were not checked; B1 is marked failed from the statement that human oversight fell short; both are judgements about mapping. No remediation adds a listed control, so remediations is empty; the article removals and suspension are recorded in event.remediation only. Timeline entries have no stated dates. Severity major is a judgement based on the stated count of seven affected parties, which is an allegation. The model version, developer, and lifecycle stage are not stated.
