Interface Regimes and Phenomenological Accessibility

Physical phenomena are accessible only through specific observational and inferential interfaces.This work introduces the concept of Interface Regimes (IR) as a structural condition for phenomenological accessibility, independent of the underlying physical ontology. An interface regime specifies the operational constraints under which physical states can appear as phenomena, namely through physical coupling, trace persistence, comparability, and partial invertibility of the observational mapping. The absence of a signal is therefore not interpreted as evidence of ontological absence, but as a possible consequence of inactive, collapsed, or incompatible interface regimes. The framework introduces no new…
