Data-loss recovery-mode status (snowflake native app).

Whether the metadata database was recreated empty after this install had already served (DVT-3483, child of DVT-3481). While active, the stock Example dashboards are NOT seeded and admins are shown the last known-good timestamp until the loss is acknowledged with CALL app_public.acknowledge_data_loss('MY DATA IS MISSING');. Admin or owner only (audit:read). Outside snowflake mode, or with no recovery record, returns active: false with all timestamps null. A read failure is a 500, never active: false.
