The turn role — answer, correction, side_query, new_request, cancel, plus the
not_applicable a resolver may return — decided from what the router made of the

from a question: 'а что если в 11:00' leaves nothing of its own behind and
'какая сейчас погода в Риме' leaves the weather and Rome. Nothing calls it yet.
