YouState Diagram - Order lifecycle: draft → pending → paid → shipped → delivered; with cancellation and refund transitions.
AII will design a linear horizontal flow for the main order lifecycle (Draft to Delivered) to maintain a clear primary path. The alternative termination states, "Cancelled" and "Refunded," will be placed in separate rows above and below the main sequence, respectively, using orthogonal connectors to ensure a clean, non-overlapping layout.
