I Governance Before Intelligence A Pre-Execution Substrate for Deterministic Refusal, Authority Validation, and Continuity Preservation Version 0.9.7.1

ELYON-SOL Whitepaper (v0.9.7.1 — CANONICAL): Governance Before Intelligence – A Pre-Execution Substrate for Deterministic Refusal, Authority Validation, and Continuity Preservation Description: This is the v0.9.7.1 canonical release of Elyon-Sol, a governance-first pre-execution substrate that determines whether an interaction should exist at all, prior to any policy evaluation, intelligence, or execution. Elyon-Sol acts as a lightweight, non-executing legitimacy gate under a strict fail-closed model. It enforces three independent governance invariants: AC³ (Authority Construct) — Legitimacy: Are all required authorities present, identifiable, and properly scoped? T²⁶ (Coverage Model) — Completeness: Are all necessary participants, roles, and evidence present? CCS (Continuity Control Surface) — Identity preservation: Does the system maintain structural and semantic consistency across state transitions? The framework also defines four interaction-level failure constructs (observational detection models): CDD — Consent Deadlock SAP — Service Access Paradox PAD — Policy Authority Disclosure ILT — Illegitimate Loop Termination Key improvements in v0.9.7.1: CCS formally tightened with explicit ternary state representation s = (u, c, d), change detection, and justification-based transition rules (now fully evaluable and bound to AC³/T²⁶) New Appendix B with two worked end-to-end evaluation examples demonstrating deterministic refusal in real interaction patterns (anonymized) Consolidated single-document artifact containing narrative, embedded formal model with proof-style definitions, full failure constructs layer, and deterministic trace mapping The work is grounded in observed patterns from healthcare, finance, and insurance domains and includes high-level alignment with obligations under the EU Artificial Intelligence Act (risk management, human oversight, prohibited practices).
