The Ledger Principle: A Typed Cross-Domain Framework for Observation, Commitment, Persistence, Constraint, and Governance

Technical architectures, institutions, and organizations face a recurrent problem: how does a state become consequential for what can happen next? Existing literatures provide established accounts of observation, information processing, authorization, persistence, state-transition constraints, feedback, accountability, and governance. The physical information-thermodynamic domain is retained only as an exploratory boundary case rather than as a co-equal evidence family. This paper proposes the Ledger Principle as a typed analytical framework linking state, observation or verification, registrable information, commitment or authorization, persistence, constraint, action or execution, outcome, and feedback. The sequence is not claimed as a new control loop: cybernetic control architectures, MAPE-K, and OODA already formalize recurrent observe-analyze/decide-act-feedback structures. The contribution is a synthesis-level one: the joint typed articulation of registrability, commitment, persistence, consequence coupling, attribution, role separation, representational plurality, and governed transformation within established state-to-action loops, combined with a restrictive strong- ledger condition and an explicit structural-correspondence-without-mechanism-identity discipline that supports failure localization. The Ledger Principle holds that observed or verified states enter a durable state-to-consequence relation when they are rendered registrable, coupled through valid commitment or authorization to persistent consequences, and thereby alter the admissibility, authority, accountability, incentives, interpretation, or revision conditions of subsequent states or actions. Persistence alone does not constitute a ledger. A strong ledger additionally requires attributable commitment history, provenance, and consequence rules that make prior commitments operationally relevant to present admissibility or accountability. The framework further addresses role separation, multiple rule-valid representations of the same underlying state, and governed transformation between such representations. A1-A5 are stated as architectural axioms that define the framework vocabulary; P1-P3 are propositions concerning role separation, representational plurality, and governed transformation. Practical constructs include failure localization, Ledger Translation Burden, bounded delegation, and a proposed Ledger Assessment profile. These are design and research proposals rather than validated metrics or standalone theories.
