Ontologia_do_Estar__Infraestrutura_Neutrínica_como_Hardware_de_Registro.

English: Abstract This paper formalizes the foundations of the "Ontology of Being" (Ontologia do Estar), a deterministic cosmological framework that reinterprets the traditional quantum vacuum. It posits that spacetime is not a sterile void, but rather a physically saturated computational hardware maintained by a constant background density of neutrinos. This medium serves as an infrastructure for universal metadata registration and permanent storage. The framework challenges the classical paradigm of metric spatial expansion, replacing it with the concept of Spectral Rutilance, which describes a photon's fractional energy loss due to mechanical friction when traversing this dense substrate. Furthermore, neutrino flavor oscillation is reclassified as a parity-check protocol—acting as both a thermal and informational checksum—that ensures the stabilization and integrity of the macro-system without entropic dissipation.
