Crystallism: A Boundary-Condition Methodology for Modeling, Decision, and Structural Stabilization in Complex Systems

This preprint presents Crystallism as a boundary-condition methodology for the analysis of complex systems. Its central claim is that clarity is achieved not by eliminating subjectivity, but by making the boundary of applicability of a model explicit. On this basis, Crystallism reframes objectivity as a structured condition: a statement becomes objective not by being universally detached from all perspective, but by being valid within a declared regime of scale, level, time horizon, language of description, and purpose of analysis. The paper states the minimal conceptual core of the framework in citable form. It introduces the generative sequence Boundaries -> Structure -> Identity -> Clarity; defines decision necessity as a structural condition of constrained systems rather than a merely psychological phenomenon; and presents subject-state as a derived configuration of bounded, energetically constrained, and informationally limited systems. It also clarifies the methodological scope of the framework: Crystallism is not a theory of everything, not a belief system, and not a completed formal theory. It is a discipline of structured reasoning designed for domains in which multiple admissible descriptions, incomplete information, constrained choice, and interpretive instability coexist. This first publication is deliberately limited. It establishes a minimal conceptual core that is sufficient for critique, citation, and future development.
