The brain graph counts node_executed events client-side and the websocket is torn down on every shell change, so anything a flow published during the navigation gap was lost. The bus now keeps a session tally per qualified node and the snapshot hands it back, letting a reconnecting client catch up. Both the route and the tunnel connector build that snapshot from one helper so the portal cannot drift from the direct connection.
