Abstract

The VTI Standard establishes a deterministic framework for binding authorization decisions to verifiable evidence at the moment of enforcement. It defines canonical trust-state representation, authorization outcome binding, and verification-linked enforcement requirements suitable for regulated and high-assurance digital environments.

Core Invariants

  1. Authorization = Evidence
    Authorization decisions MUST produce verifiable evidence.
  2. Canonical Trust-State Integrity
    Trust-state MUST be represented in deterministic canonical form.
  3. Enforcement Bound to Verification
    Enforcement MUST be cryptographically and logically bound to successful verification.

Scope

The VTI Standard applies to systems where authorization decisions carry legal, financial, regulatory, or operational consequence and must withstand independent audit and verification.
