Classifies an incoming signature as one of three scopes: (1) payment-capability only, the signature proves the wallet moved value but nothing about intent; (2) delegated intent, the signed payload binds principal, agent ID, and purpose; (3) policy-conforming authority, the payload also references the governing policy, quote hash, or delegation record.
