SAFE-Matter™ Anti-Spoofing and Signal Authenticity Framework: A Governance Specification for Non-Falsifiable Operational Evidence in Life-Critical Safety Systems

SAFE-Matter™ is a deterministic evidential safety governance system that evaluates the operational condition of life-critical safety functions at the moment of reliance.This document forms part of the SAFE-Matter™ v2 Framework for Non-Falsifiable Operational Evidence and defines the conditions under which evidential inputs may be accepted as authentic and resistant to falsification.The framework establishes that evidence cannot be accepted solely on receipt. It must satisfy independent conditions of authenticity, integrity, temporal validity, and behavioural plausibility. These conditions are not supplementary controls. They are conditions of evidential acceptance. Where any condition cannot be satisfied, evidence is treated as untrusted and excluded from reliance.SAFE-Matter enforces these conditions deterministically through cryptographic identity binding, integrity validation, temporal verification, behavioural consistency analysis, and cross-system correlation. Evidence is continuously evaluated against defined acceptance criteria and recorded within a tamper-evident Trust Ledger, enabling independent verification of system condition at any point in time.The framework assumes adversarial conditions, including spoofing, tampering, replay, and signal manipulation. It does not attempt to eliminate falsification. It renders undetected falsification non-viable as a basis for reliance.Failure to verify evidence results in deterministic degradation of Trust Score and transition to defined system states, including degraded, critical, or unverified. In these states, reliance on the affected system is not permitted.SAFE-Matter replaces assumption with explicit evidential conditions, ensuring that safety is not inferred from prior certification or historical data, but determined through continuously verified operational evidence.
