They do not state when the paper was written or when the AI-generated references were introduced, so no date_occurred is given. The sources do not state how the problem was detected, so no detection_method is given. The sources do not state a root cause or a responsible party, and they do not say whether an autonomous agent was involved, so agent_involved and all failure-class fields are left out. No control is recorded as held, failed, got around or missing because the sources do not state one. The disclosure date 2025-12-17 is an inference: the university announced findings on Wednesday, and the article is dated 2025-12-17, which is a Wednesday. The retraction day 'Monday' and the publication month 'October' are kept as stated, without conversion. The university's vow to strengthen training is reported as a stated plan, not a change made, so no remediation entry is given. The severity tier minor is a judgement applied to the stated facts. The context.industry value is an inference from the university setting.
