Mist runs
Bind a saved Start instruction to one Desktop run claim
Only the original authenticated requester may accept, with current execution permission. Desktop supplies a fresh per-receiver run id and an authorized company theme. The task’s observed version and preview source snapshot must still match. A chosen preview discussion must belong to the task and selected theme; zero discussions permit a standalone run. Acceptance atomically records the receiving actor and theme and invokes the existing Multiplayer run claim. A competing receiver is refused; an exact retry of the winning run id reads its claim without creating a second run. Desktop must not dispatch twice. A cloud request is accepted only with the run id Rails reserved for its box. A request carrying the person’s reply is accepted only by a run that read it (reply_read), so the answer never goes unread. A first claim on a ticket an agency is building is refused with 422 (details.type agency_building); a claim already made is read as it was.
