+**System messages** (from sender `system`): the higher-urgency
+lifecycle + Q&A events (`hive_sh4re::manager::HelperEvent`) are
 delivered as regular inbox messages (same `recv` path; body is a JSON
 object with an `event` discriminant field). The **submitting agent**
 (the root agent for top-level containers; an agent with the `approvals`

+notices — `spawned`, `rebuilt`, `killed`, `destroyed`, `needs_login`,
+`logged_in`, `config_ready` — skip the inbox entirely: they land as
+todos on the submitting agent's in-container todo socket instead
+(`Coordinator::push_todo`/`push_todo_submitter`, `subsystem = "core"`),
+which still wakes a turn (the todo-wake path — see [Turn
+outcomes](README.md#turn-outcomes)) but via a generic "call
+`get_loose_ends`" prompt rather than the event body itself. Full

 [`docs/approvals.md` § Helper events](../approvals.md#helper-events-to-the-submitting-agent).
