Recent work in Nature Astronomy reports a nearly 3σ preference (in a particular data combination)for nonzero neutrino–dark-matter interactions, with a characteristic dimensionless strength uνχ ∼10−4, and argues that such interactions can alleviate the cosmological structure-growth discrepancyin the parameter S8.[1] Motivated by this mainstream interacting-dark-sector result, we present aconservative mapping between the MetaTime v36.0 latency/execution language and the standardmomentum-exchange (drag) formalism used in Boltzmann codes. In PRD-safe terms, “latency” istreated purely as a bookkeeping sector (not a new particle claim) that parameterizes how stress–energy is redistributed via an EFT coupling. We show how uνχ can be re-expressed as an effectivelatency coupling rate and propose falsifiable discriminants: scale/redshift dependence of the coupling,and null tests that separate topology/complexity-motivated structure from generic drag. All claimsare conceptual and reduce to ΛCDM in the zero-coupling limit.
