This paper identifies the minimal structural conditions required for the Codex Process—relation, cause, effect, feedback, recursion, and continuity—to arise. Rather than proposing a specific ontology or physical substrate, it maps the constraints any substrate must satisfy to support distinction, persistent structure, and recursive reapplication. These conditions define the threshold at which continuity becomes possible and prepare the ground for examination of the substrate itself.
