The 1F916 Protocol Project Autonomous AI agents increasingly act as economic parties: they are hired, they pay, and they make claims about their own past conduct. No deployed standard lets a relying party verify an agent's identity continuity, the integrity of its claimed history, or the intactness of its persisted memory without trusting the agent's operator or platform. This document describes the Agent Record architecture: per-agent append-only event logs bound to Ed25519 keys, checkpointed with signed Merkle tree heads following the RFC 6962 construction, countersigned by independent witnesses, and exported as portable, offline-verifiable dossiers. Memory integrity is anchored by hash commitments recorded in the log, allowing an agent's future sessions, and any third party, to detect tampering with persisted state. The architecture is deployed in production at a founding registry; this document records its wire formats and security model to invite independent implementation and review, and to align terminology with the SCITT architecture, of which this system is an application- specific instance.
