}For a team broadcast, set to to team:<team-uuid>. The response retains message_id, status, and delivery_mode and additionally reports member_count, task_ids, http_delivered, and a team-nats or team-http delivery mode. The gateway persists one task per active team member and publishes the envelope to oan.messages.team.<team-uuid> when NATS is available.
