The Elyria Codex: Foundations of Admissibility, Consequence, and Governance

The Elyria Codex is a formal technical report defining a governed consequence architecture for AI-enabled and automated systems. The report introduces Elyria as a consequence-boundary architecture in which execution is not assumed by default but admitted through present-tense validation of authority, evidence, admissibility, burden, continuation legitimacy, and protected-effect standing. The work distinguishes post-hoc governance from pre-effect governance and formalizes the Elyria Boundary as the point where proposed motion must prove standing before consequence may bind. It defines core runtime objects including proposals, continuation objects, law layers, consequence signatures, receipts, witness frames, and replay surfaces. The report also establishes bounded claims, implementation posture, and the relationship between formal governance language and public proof surfaces. This publication is part of the Elyria Governance Architecture Series.
