In the context of a cart abandonment use case, where a user adds items to their cart but does not complete the purchase, how does Adobe Experience Platform (AEP) ensure that these users are correctly added to the "Cart Abandoners Audience" segment after the specified 1-hour time condition, especially in the absence of any new events occurring within that hour? Additionally, how does AEP utilize streaming evaluation and scheduled re-evaluation to handle this scenario and ensure timely and accurate segmentation?
