AI Governance Before Intelligence A Pre-Execution Substrate for Deterministic Refusal, Authority Validation, and Continuity Preservation Version 0.7.5 — Canonical

Modern AI and policy-driven systems optimize for correctness, performance, and compliance, yet lack a mechanism to determine whether an action should be considered at all. This work introduces Elyon-Sol, a governance-first substrate that operates prior to execution, enforcing deterministic refusal based on consent, authority, coverage, and continuity constraints. Elyon-Sol formalizes three core governance layers: Legitimacy (AC³) — Is the action allowed? Coverage (T²⁶) — Is anyone or anything missing? Continuity (CCS) — Is the system still valid across contexts? Additionally, this work identifies four interaction-level failure invariants—Consent Deadlock (CDD), Service Access Paradox (SAP), Policy Authority Disclosure (PAD), and Illegitimate Loop Termination (ILT)—derived from qualitative empirical observations across real-world systems. Together, these constructs establish a pre-execution governance layer capable of refusing invalid interactions before any policy evaluation or execution occurs.
