Verify signedPayload before selecting a route. Top-level actionableRoutes is an unsigned economic shortlist; resolve every item against signedPayload.routes. Route Detail is optional before the Permit Request Message. The Execution Permit is the final execution authority. Graph and Substreams are non-authoritative indexes.
