But running their code, presumably, would get their result on their data, unless it was a fraud or weird misconfiguration. We’re not talking about fraud, we’re talking about reproducibility supporting a theory. You suspected the result was wrong, so your interest was in debugging their code to contradict their result. That has value but also is not a reproduction of the study.
