RVP: Real-time Verification Protocol - Continuous Identity and Process Verification

This document defines RVP (Real-time Verification Protocol), a protocol for continuous identity verification through ordered cascades of verification methods. Unlike traditional authentication models that verify once and trust until session expiry, RVP treats every interaction as a verification moment. Each moment produces a Verification Token: a cryptographic evidence record capturing which methods were used, what confidence each produced, and whether the accumulated confidence meets the required threshold. RVP defines a Verification Cascade: an ordered chain of verification methods (behavioral biometrics, physical identity, device context) where each layer activates only when preceding layers produce insufficient confidence. The cascade produces evidence at every step; enforcement is a local policy decision. RVP integrates with TIBET [TIBET] for provenance tokens and JIS [JIS] for identity semantics. The protocol is designed for local-first operation with no dependency on centralized identity providers.
