+-- agents:    one row per Target agent the controller has ever seen. Updated
+--            with each connection + heartbeat. Serves as audit trail — we
+--            never delete rows, so an agent disappearing from the network
+--            doesn't wipe its history.
+-- instances: one row per declared game server. The controller, not the
+--            agent, is the source of truth for "instance X exists". Status
+--            is updated from InstanceStateUpdate messages streamed up from
+--            the agent that owns the instance.
