Whether stages describes a strip of this kind — undefined when it does, a Refusal
naming the offending stage when it does not. The order itself is never judged here.

(UNKNOWN_ENUM) and a repeat (DUPLICATE_MEMBER), so the two facts left are the ones only a
KIND can answer: a stage this kind does not have, and one it has that the list left out.
