Sui to Arbitrum: object and account boundary

A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Sui and Arbitrum use different network identities, gas assets, wallet support, confirmation behavior, and destination conventions. Validate each side independently in the current route.
