The supplied Android recording and running emulator showed an empty sealed Explorer after switching type/series, including missing grouping controls. The list reused one native instance while changing sticky-header layout and moving between a header-only series tree and product data.

Give each structural mode a separate list identity and disable native subview clipping for this list. Keep FlatList windowing, pagination, sticky filters and existing per-selection scroll restoration. No catalogue, account or holding data changes; no backend work.

Validation: lint/TypeScript passed; Jest 3,016 passed, 11 skipped. Regression coverage verifies list identity changes and attached header children, alongside the existing price, paging, series-return and scroll restoration tests. The Maestro scenario adds repeated grouping switches but was not executed because Maestro is unavailable locally.

Android release build passed and was installed in-place without uninstall or data clearing. Four type/series round trips retained the tree, filters and products; a scroll kept the type controls sticky. UI hierarchy and screenshots were inspected. iOS has not been tested; occurrence exclusively on Android is not established.

Delivery: app PR #858 targets staging, not merged. The local emulator has this fix on top of staging; it does not contain the separate pending email-required feature (#856). No VPS deployment, migration, scan, login or collection write.
