SAFE-Matter™ SM-EIS Telemetry Interface Specification

This document defines the SAFE-Matter™ External Interface Specification (SM-EIS), which provides the signalling mechanism used to expose operational trust states to deterministic enforcement systems.The specification describes the SM-EIS event model, trust-state signalling structure, heartbeat mechanism, and fail-safe behaviour used by SAFE-Matter to communicate governance outcomes to external safety hardware.The interface allows enforcement systems to subscribe to SAFE-Matter trust signals without requiring access to internal trust evaluation algorithms or operational evidence processing.This document complements the SAFE-Matter™ Telemetry, Identity and Trust Engine Architecture and defines the external telemetry interface through which SAFE-Matter governance decisions are communicated to safety enforcement systems.
