Can a research agent tell when its own calculation has led it astray? In FrontierPhysics, physicists turned investigations from their own laboratories and research groups into 56 problems. An agent receives a brief, explores the literature, chooses a method and submits a manuscript alongside results that an examiner can check. The strongest configuration passed 46 of 168 trials. It solved 25 problems at least once in three attempts, but only eight on every attempt. The most revealing findings emerged when physicists revisited the experimental records. Some agents had checked a result using the very assumption that produced it. In other cases, a sound answer had failed the examiner’s test. Nine such judgements changed in the detailed audit of one configuration. Together, the repeated trials and the expert review illuminate a practical question for any physicist considering an agent’s work. What evidence would persuade another researcher that the result survives a genuinely independent check?
