Schema: ItemPurchaseCatalogEntry (single table). Per-viewer quota tracked via existing ViewerEventCounter keyed by "item_purchase:<id>" with period JstPeriod.MonthKey when IsMonthlyReset else AllTime. Controller: - /info returns catalog + per-period rest (server-computed max(0, PurchaseLimit - counter)) + user_card_pack_ticket_list (every Items.Type==2 row joined to viewer count, zeros included — client unconditionally UpdateItemNum's each entry). - /purchase: sold_out check before currency check (no counter increment on currency failure), inline TryDebit covers RedEther/Crystal/Rupy/Item with post-state-total reward_list entry, grant via RewardGrantService. Request `rest` accepted but ignored (server counter is canonical). Importer mirrors PaymentItemImporter shape — idempotent find-or-create, seed-missing rows preserved. 3 entries from the prod capture. 486 tests pass (was 476; +10 item_purchase tests).
