Readings in the requested order; 1/2 mapped to base/alt under both orders;
UNSURE, an unparseable or out-of-range reply is unsure rather than a guess; an
empty reading is described, not blank; a model error is an error, distinguishable
from 'unsure'. The optional order-checked wrapper asks twice with the order swapped
and keeps only agreement.
Red: Request, Verdict, NewLLMAdjudicator and NewOrderChecked are undefined.
