Routes are GET /api/desk/{mind}/forks, GET /api/desk/{mind}/forks/{fork_id}
and POST /api/desk/{mind}/answers with fork_id still in the body (Heimdall's
file 4.2 and 4.3a). Spec: the {mind} segment rules M1 to M5 (fixed configured
list, never joined into a path, unknown Mind is the unknown-fork refusal with
the same bytes, the route's Mind must hold the fork_id, scopes not per Mind,
the decider list is Bifrost-to-Huginn only, marked Bifrost/Huginn work).
Schema: read_request carries `mind`. Vectors: transport.mindRoutes (47 cases,
sameResponse pairs, the socket a judge would open), scenarios for a body that
names `mind` or `deciders` (body_unknown_field), read_request with the Mind.
Both judges replay them; both also assert on every scenario that a request id
bound by another account never returns that account's answer id or document
(V14), with `of` allowed to name the counted answer. Open choice 11: an
unreachable known Mind answers unavailable, an unknown one fork_unknown.
