This work presents the canonical CRIS framework (Consistency, Recursion, Invariance, Selection) as a minimal and universal constraint system governing re-identification across time. The framework formalizes persistence without contradiction as an existence filter: any system that can be coherently re-identified across iterations must satisfy these conditions. The result is a closed, non-empirical mathematical criterion independent of physics, probability, or ontology.
Christopher Lamarr Brown (Sat,) studied this question.
