Hierarchical Conditions of Information Retention and the Structural Foundations of Existence

This paper investigates the structural conditions under which information retention—understood as the sustained reproducibility of correlation structures—can be maintained across hierarchical layers of reality. Departing from a purely metaphysical ontology, the study adopts an operational stance in which existence is defined through distinguishability and re-identifiability over time. On this basis, information retention becomes the operative condition of existence. Three candidate conditions are extracted and examined: (1) fluidity, expressed as the Flux/Stock (F/S) ratio; (2) indeterminacy, formalized as LEFFLA (Latent Evaluative-free Floating Locus of Abeyance), representing structurally admissible yet unactualized state-space volume; and (3) temporal coherence between feedback time and structural change time. These are interpreted respectively as preservation, generative, and control conditions of correlation structures. The paper argues that these three conditions are demonstrably indispensable at the physical and biological layers, and structurally isomorphic at the levels of consciousness and civilization, although strict proof becomes increasingly difficult at higher layers. The impossibility of full verification does not logically entail dispensability. Given the asymmetry of irreversible collapse, precautionary rationality favors maintaining these structural conditions. The study concludes that fluidity, indeterminacy, and temporal coherence constitute strong candidates for hierarchical constraints on information retention, and thereby for the operational foundation of existence.
