Each role has a named persona agent: Raj for admin, Marcus for brands, Camila for reps, Li for buyers, Taylor for distributors, Kwame for merchandisers, Mina for marketers, Luka for manufacturers, Harper for shippers, Bao for storers, Priya for suppliers, and Jake for funders. They run on the Anthropic SDK and brief participants in the voice of their role. Exactly these twelve — a hard product invariant.
