Not stated: model name and version, the exact date of filing or disclosure, the ChatGPT conversation content, any response from OpenAI, and any remediation. No autonomous agent is described, so agent_involved, failure_class and trigger are left out. Root cause and responsible party are not stated by a source and are left out. Judgement: the alleged failure to warn is mapped to D1 (safety training and refusal) with outcome failed, as an allegation. Judgement: severity set to severe on the safety-of-life test, based on the alleged death. The 2026-07-22 article date is page metadata, not a disclosure date, so date_disclosed is left out.
