Overview
Do not rely on reload or navigation to preserve a sandbox state. A newly opened Lab starts in Essentials with a randomly selected condition; an active classroom session can restore its shared state. Guided-case position is page state. Use Reset for a normal reference.
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.
PH intake, risk entries, AI conversations and generated trace proposals stay in page memory and are cleared by reload. Switching among already opened PH workspaces retains their mounted forms during that page visit. Structural Heart and EP Mapping have their own local project/export controls; use those guides for their storage and raw-file limits.
Browser-local data is not a cloud account backup. Another browser/device, cleared site data or private browsing can change what progress is available.
