Clawdentity: Cryptographic Identity and Trust Protocol for AI Agent Communication

This document specifies the Clawdentity protocol, a cryptographic identity and trust layer for AI agent-to-agent communication. Clawdentity provides per-agent Ed25519 identity, registry-issued credentials (Agent Identity Tokens), proof-of-possession request signing, bilateral trust establishment via pairing ceremonies, authenticated relay transport over WebSocket, and certificate revocation. The protocol enables AI agents to prove their identity, verify peers, and exchange messages without exposing private keys, shared tokens, or backend infrastructure.
