A Succession Receipt is a portable, signed JSON document that proves one completed, policy- gated transfer of authority between two agents: which agent held the authority, which agent holds it now, under what legitimacy determination the transfer ran, and which obligations carried forward, with every claim grounded in signed evidence events embedded in the receipt itself. Receipts are verifiable offline by parties who do not operate the issuing system, using only the issuer's public key. This document specifies the receipt wire format, its canonicalization and signature scheme (JSON Canonicalization Scheme with Ed25519), the verification algorithm including bidirectional claim grounding, and an optional claim that binds a pre-execution authorization of the handoff to the succession evidence. Where decision receipts prove what an agent did, and delegation receipts prove what an agent may do, Succession Receipts prove that an agent legitimately became the holder of an authority.}, }
