SAFE-Matter™ Runtime Admissibility and Trust Governance Specification Deterministic Runtime State Governance, Trust Computation, and Execution Authority for Life-Critical Systems

SAFE-Matter™ Runtime Admissibility and Trust Governance Specification defines a deterministic runtime governance architecture for operational admissibility, trust computation, evidential continuity, dependency propagation, and execution authority within life-critical systems. Conventional operational assurance systems commonly inherit trust from historical certification, prior inspection, operational continuity, or assumed system persistence. SAFE-Matter™ instead continuously recomputes whether operational execution authority remains constitutionally admissible through valid present-state evidence existing at the exact moment reliance occurs. The specification formalises runtime admissibility states governing operational authority, including ADMISSIBLE, DEGRADED, ESCALATED, UNKNOWN, and NON-ADMISSIBLE conditions, together with deterministic transition governance controlling escalation, degradation, suspension, recovery, isolation, and revocation of operational execution legitimacy. The document further defines SAFE-Matter™ Trust Score computation as a constitutional evidential governance process rather than a probabilistic confidence metric, telemetry score, predictive analytics estimate, or inherited operational trust condition. Trust computation continuously transforms sufficiently attributable, temporally valid, dependency-coherent, cryptographically authentic, and operationally corroborated present-state evidence into runtime operational legitimacy. The specification additionally formalises dependency propagation governance, temporal admissibility decay, severity weighting, escalation influence, hysteresis stabilisation, recursive governance computation, distributed runtime admissibility propagation, and deterministic enforcement threshold governance across interconnected operational environments. SAFE-Matter™ therefore transforms runtime operational governance from assumption-based continuity into continuously recomputed evidential legitimacy operating at the exact moment operational reliance occurs. The governing condition remains irreducible: Execution authority may continue only while admissible present-state evidence remains continuously provable at the exact moment operational reliance occurs.
