 - Atlas Overview is the Grafana home (1h range, 1m refresh), Overview folder UID `overview`, internal folder `atlas-internal` (oceanus-internal stub).
 - Panels standardized via generator; hottest row compressed, worker/control rows taller, root disk row taller and top12 bar gauge with labels. GPU share pie uses 1h avg_over_time to persist idle activity.
 - Internal dashboards are provisioned without Viewer role; if anonymous still sees them, restart Grafana and tighten auth if needed.
+- GPU share panel updated (feature/sso) to use `max_over_time(…[$__range])`, so longer ranges (e.g., 12h) keep recent activity visible. Flux tracking `feature/sso`.
 
 ## Upcoming priorities (SSO/storage/mail)
 - Establish SSO (Keycloak or similar) and federate Grafana, Gitea, Zot, Nextcloud, Pegasus/Jellyfin; keep Vaultwarden separate until safe.
