Five public benchmarks are inspected. ToMi: Sally-Anne object-location stories (999 narratives per OpenToM's table; paper body not read). Hi-ToM: generated stories with five agents and one question each at orders 0 to 4, optional public or private deceptive statements. OpenToM: 696 narratives with 23 first- and second-order questions each (location, multi-hop container/accessibility, attitude). FANToM: 256 conversations in which a character leaves and rejoins; belief, answerability and information-access questions. SimpleToM: two-sentence everyday stories, 1147 per category, with awareness, behaviour and judgment questions. All are template-built or LLM-generated; none uses published fiction.

Curator qualifications: Five ToM benchmarks compared (ToMi, Hi-ToM, OpenToM, FANToM, and others) by story type, orders and question types. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
