  Derived from components.schemas of openapi/hergertsynthora-com-mesh-aggregate-openapi.yml (ServiceRequest,
  SignedResult, PaymentRequirements), the inline request/response schemas of the 59 per-service specs under
  openapi/services/, the notary inputSchema (A2A card, MCP tool and 402 body agree), and the x402 manifest.
description: >-
  A deliberately small model: every product takes one request object and returns one signed verdict envelope;
  the only cross-object references are the payment references that tie a result to a settlement on Base.
