Astrognosy AI This document defines the "reason://" URI scheme and associated registry protocol for naming, storing, and retrieving compressed structural reasoning artifacts across distributed autonomous agent networks. An artifact enters the registry only by winning a live competitive arbitration round scored by the Web Agent Reasoning Federation (WARF) protocol. The artifact schema contains no raw data fields; the structural representation is mathematically non- invertible (empirical reconstruction rate r = 0.0149). The protocol is designed to function as open infrastructure — analogous to DNS for network addresses or HTTP for document retrieval — for the agentic internet.
