DeskResponse declares Answered { answer, counted_answer_id, as_of: u64 }, Forks { list, as_of: u64 } and
Fork { entry, as_of: u64 } (desk_wire.rs at b299d6f7; the golden replies carry exactly those keys). The door now
requires as_of as an unsigned integer and refuses any other key, like every other contract map. First red: the six
wrapper tests (missing, nil, negative, text, bool, array, object as_of; extra keys).
