++ *                ends. The task is the visitor's when they are signed in (their own subject id in X-OV-Subject, so

++ *                visitor has no account, and Chat never borrows one for them.
++ *   read({...})  GET /api/v1/tasks/:id, for a turn still running when the wait ended (the next view reconciles it).
++ *
++ * A turn the model cannot answer (refused, failed, cancelled) throws a TurnError whose code and detail are the
++ * task's own: the product shows those words. A turn still running when the wait ends resolves { pending: true,
++ * taskId } instead of throwing, so the product can reconcile it on the next view.
