 * The two error types that mean "this interview question was not decided".

 * Callers catch these to distinguish a question that was never decided from one
 * that was answered — the distinction `module update` conflated when it reported
 * a breaking update as "operator declined" that no operator had ever seen. The
 * two are not interchangeable: *unanswered* means no responder could even be
 * found, *abandoned* means a responder existed, the question stood, and the
 * deadline passed with nobody deciding.
