ATP Core Test Vectors

This document publishes golden test vectors for the Agent Transaction Protocol (ATP) [ATP-CORE]. The vectors cover canonicalization (RFC 8785 JCS), nodeId computation, and Ed25519 signature generation and verification. ATP Core conformance per [ATP-CORE] Section 13.7 requires that conformant implementations pass all vectors in this document for canonicalization, nodeId computation, and Ed25519 signature verification.
