usePolled takes a cache key: it saves each answer in localStorage and starts from the saved one, so opening the agents, alerts, builds, review runs or hives view shows the last data at once and the refresh spinner marks the update. A saved answer is dropped after a day, when it was saved by another build of the UI, at log out (a new onLogout of the shared user menu) and when the gateway ends the login (a new onSessionEnded of the session guard). Pages with an editor (schedules, notification flows, broadcast) do not use it.
