  "summary":"ACL 2026 adds a missing distinction: a model's hidden states can contain privileged information about its own correctness without establishing that the model itself can access or report that information introspectively. Standard evaluations can mask this signal because models often agree on which items are difficult; disagreement subsets reveal domain-specific privileged information for factual knowledge but not mathematics.",
