+//      Emitted via getChatLockEntity (Connections.hs:54) / getConnectionEntity
+//      (Connections.hs:93) when an async agent event references a connection
+//      whose row was just deleted by deleteMembersConnections'.
+//   2. ChatError.ErrorAgent with empty agentConnId + CONN NOT_FOUND.
+//      Emitted at Subscriber.hs:112 (processAgentMessage _ _ "" (ERR e)) when
+//      the SMP agent sends a bulk ERR after teardown.
