The clarified beta requirement is a fresh Explorer after leaving the tab and returning, including collapsed blocks. The previous route reset left a separate browse cache intact. App PR #921 now clears that cache before entering Explorer from another tab: expanded blocks, scroll offsets, mode, sealed search text and type/series selections return to their defaults for both games.

Normal Back within Explorer retains the current browse journey. Account, collection and persistent preferences are not reset. This is a follow-up to the beta umbrella #868 and navigation issue #869.

Observed Red/Green uses the real NavigationProvider and browse cache. The route already returned to explore, but expanded sv/me and scrollY 420 remained until the fix. Three regressions cover cards, sealed selections across scopes and detail Back preservation. Lint/typecheck passed; 36 focused tests and 3,230 full Jest tests passed, with 11 skipped. The non-destructive Maestro flow was updated but not run because Maestro is unavailable. No device result, merge or deployment is claimed. No production or account data was changed.
