// Aicent Stack | RPKI (Resource Public Key Infrastructure)

//! # RFC-003: Merkle-DAG Identity Provenance
//! 
//! This module implements the "Root of Truth" for the Aicent Stack. 
//! It utilizes a distributed Merkle-DAG to provide Route Origin Authorization (ROA) 
//! for AI Task Primitives, evolving the principles of RFC 6480 for sub-ms telemetry.
