inventoryId semantics: the event bridge identifies custom Inventories through an Inventory reverse-lookup table. In scenarios with multiple custom Inventories, use inventoryId to accurately determine which inventory a click/close belongs to, instead of relying on inventoryType=CHEST + slot inference.
