Constrained Informational Systems: A Structural Framework for Lawful Emergence Under Constraint

This preprint introduces Constrained Informational Systems (CIS), a structural framework for analyzing how structure and system behavior emerge under constraint in meaning-bearing systems. The framework treats constraint as a primitive structural feature shaping allowable transformations within informational state spaces, rather than as a normative rule, control mechanism, or agent-driven influence.

CIS characterizes semantic entropy as dispersion in interpretive alignment across a system and shows how varying constraint regimes produce identifiable failure modes, including over-coherence, paralysis, and irreversible collapse. The paper proposes observable system-level signatures of these dynamics and delineates conditions under which semantic phase transitions occur, without appeal to belief change, persuasion, or subjective intent.

This work is intentionally domain-agnostic and structurally defined rather than metaphorical. Formal mathematical instantiation, domain-specific application, and empirical modeling are deliberately deferred to subsequent volumes. This preprint represents the first public component of a staged research program concerned with lawful emergence in constrained informational systems.

This record is part of a two-paper research sequence reviewed as a linked pair in an independent technical review. The review includes this work (CIS v1.0.2) and a subsequent architectural instantiation paper. The review reflects an independent technical assessment and does not constitute endorsement or co-authorship. The version-linked review is available in the associated Constraint Architectures preprint record.
