Actors
Shipper
The company sending the goods. Customer of a 3PL or carrier; originator of the order, owner of the SLA, payer for the move. Same role is often called the merchant in retail and e-commerce flavor and shipper in freight and logistics flavor.
Where this fits
The people, brands, and counterparties Nash coordinates across. Operators set the rules, dispatchers run the live loop, drivers move the order, and merchants own the promise the customer paid for. Every actor sees the surface designed for their role.
