Read before routing and only when a list is bound: with nothing offered,
"второй" is an ordinary word and keeps routing. No verb reads it back
rather than guessing what to do with it.
Session.Candidates holds what she offered, in the order she offered it, and
SetCandidates attaches it in place so the turn already remembered keeps its
slots. tasks.Spoken is the list FormatRU actually named, so an ordinal and
the spoken order cannot drift apart.
