Study question

Evaluation design

Can an AI distinguish supported, contradicted and unanswerable claims across connected synthetic life records while preserving identity and temporal context?

Build reviewed claim labels with missing and conflicting evidence cases; report unsupported-claim rate, contradiction detection and abstention accuracy by error type.
