The stream's task_started and task_notification events carry the tool_use_id of the call that started the task. The actuator records, per task, the briefs the starting turn was answering; a briefless result after a notification answers those (any notification it cannot place answers none). While a notification's turn is open, only the conversation it is attributed to may be written. A restart reads a resolved claim's conversation by key and opens the gate for it alone. The flush result is the note to the successor, in the journal: it is no reply. The start message states the rules.
