The Three Morphological Conditions of Admissible Existence

This manuscript presents a foundational structural analysis of admissible existence: the minimal and exhaustive morphological conditions under which any domain can support empirical resolution. Rather than proposing a new ontology, physical theory, or explanatory model, the work formalizes the constraint grammar that must be satisfied for persistence, differentiation, and non-arbitrary exclusion to be meaningful in any resolvable system. The paper identifies three co-required morphological conditions; Persistence, Orderability (Proto-Time), and Bounded Admissibility (Closure–Leakage Compatibility), and proves their minimality and exhaustiveness via structural failure-mode analysis. These morphologies are shown to be logically prior to time, information, observers, laws, and representational form, and to apply universally across physical, biological, computational, institutional, and logical domains. The framework introduces χ-morphology and associated diagnostic operators as falsifiable instruments for detecting admissible stability, regime transitions, and collapse behavior under constraint and perturbation ladders, while explicitly separating unassailable logical preconditions from empirically testable claims, althought, it does not require validation by any particular domain because it formalizes the conditions under which domains can be validated at all. This work is intended as a structural foundations preprint, providing a domain-agnostic admissibility grammar that enables, but does not replace, domain-specific scientific theories. Companion papers may explore applications and empirical instantiations of the framework across specific domains.
