SAFE-Matter™ Admissibility Engine Specification: Determination of Operational Legitimacy at Runtime

This publication defines the SAFE-Matter™ Admissibility Engine Specification, the constitutional mechanism through which operational legitimacy is determined within the SAFE-Matter governance architecture. The Admissibility Engine continuously evaluates evidential conditions in order to determine whether sufficient admissible evidence exists to justify operational authority at the exact moment reliance occurs. The specification establishes the constitutional relationship between evidence, admissibility, authority, execution, and reliance, defining how evidential conditions are transformed into legitimacy determinations that govern operational authority. The publication formalises the constitutional role of evidential domains, evidential evaluation, contradiction management, Unknown-state generation, admissibility determination, authority derivation, reassessment, admissibility decay, governance consequences, and auditability requirements. Unlike traditional governance models that rely primarily upon periodic certification, inspection, audit, or compliance activities, the Admissibility Engine continuously evaluates present-state evidential conditions in order to determine whether operational authority remains justified. The specification serves as a foundational architectural component within the SAFE-Matter™ framework and provides the constitutional legitimacy determination mechanism upon which runtime governance, execution control, state determination, and enforcement decisions depend.
