Overview
Do not rely on reload or navigation to preserve a sandbox state. The root entry returns to the welcome, while explicit Lab and case URLs open their intended destination; guided-case position remains page state.
Quiz score is for the current visit. The Crimson Circuit saves best-score XP and bonus unlocks in the current browser, while the active investigation’s score is visit state.
Browser-local data is not a cloud account backup. Another browser/device, cleared site data or private browsing can change what progress is available.
