+### Fixed

+- **An open WebUI transcript now reconciles when another client/process updates it (#4205 follow-up).** The #3916/#4195 external-refresh guard made the 30-second poll correctly skip WebUI-native sessions — but it also made `refreshActiveSessionIfExternallyUpdated()` return early for *every* non-external session, so a real `sessions_changed` event would update the sidebar list while leaving the currently-open transcript stale. The early-return is now scoped to the periodic `poll` path only; `event`/focus/visibility triggers run the existing count/timestamp divergence check (guarded by the in-flight/busy/streaming locks, so no refresh loop), and `_scheduleSessionEventsRefresh` reconciles the active transcript, not just the sidebar.
