Premature Evaluation Closure Under Interface-Limited Assessment: A Minimal Synthetic Stress Test on Latent-to-Manifest Response Gaps

A controlled synthetic evaluation stress test showing that non-manifest response under one admissible interface need not imply absence of known latent structure under another admissible interface. The term closure is used only in an evaluative and methodological sense. No claim is made about human memory, mind, neuroscience, psychometrics, hidden competence, human subjects, or any broader framework.
