Active Sessions panel lists sessions that are open OR exited-but-within-grace (barrier state is unconfirmed, so a paid car is presumed possibly-present until grace expires). Row click → pay/exit modal; 'Open barrier' (paid sessions only — no payment, no button) fires a human-intervention re-pulse signed as an attributed anomaly, never a second vehicle_exit. Wiki: booth-exit-flow.md. Note: the backend (PayStation.activeSessions, ExitFlow.reopenBarrier, routes, api.ts) landed with the prior commit's shared files.
