Astrognosy AI WARF (Web Agent Reasoning Federation) defines a deterministic, identity-free protocol for arbitrating competing agent outputs. Three flows -- Xfer, Xact, and Xchange -- provide structural signature transfer, identity-free profile matching, and open semantic arbitration respectively. After Xchange arbitration determines a winner, the Xtend pipeline (VASE corpus expansion + Balmathic kappa acceleration detection) automatically quality-gates the result. If the caller supplied a valid reason:// address and kappa exceeds the promotion threshold, the winning artifact is promoted into the reason:// reasoning artifact registry at the exact URI provided by the caller. The protocol produces auditable, SHA-256 chained verdicts without exposing raw data, model weights, or agent identity.
