AI Governance Before Intelligence A Pre-Execution Substrate for Deterministic Refusal, Authority Validation, and Continuity Preservation Version 0.9.8.1

Abstract — Elyon-Sol v0.9.8.1 Modern AI and policy-driven systems prioritize correctness, performance, and compliance, yet they often overlook a foundational question: Should this interaction occur at all? Elyon-Sol is a governance-first substrate operating prior to policy evaluation or execution. It enforces deterministic refusal based on authority (AC³), coverage (T²⁶), and continuity (CCS), with failure constructs including CDD, SAP, PAD, and ILT. Version v0.9.8.1 builds on v0.9.8 by introducing formal clarification to the interaction model and continuity definition without expanding the invariant set or modifying system behavior. Specifically, Sections 11–12 have been repaired to explicitly define: the interaction structure ( I = (A, S, C, t) ) deterministic derivation of required authority and coverage via the Governing Manifest (M: I → (AR(I), R(I))) formal evaluation conditions for AC³ and T²⁶ using set inclusion an operational definition of CCS as a justified state-transition constraint with enforced decision consistency These changes remove ambiguity in how authority, coverage, and continuity are computed, aligning formal definitions with the evaluation function and deterministic examples already present in the system. No new invariants, decision paths, or execution behaviors are introduced. The admissibility boundary remains unchanged: if any invariant fails, the interaction is refused. Elyon-Sol v0.9.8.1 is therefore not an expansion, but a formal consolidation—rendering the system computationally explicit, audit-ready, and directly translatable to implementation while preserving strict minimality.
