A PRD-safe bridge between MetaTime v36 and neutrino–dark-matter interactions: Latency bookkeeping mapped to an interacting-dark-sector effective theory

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 discrepancy
in the parameter S8.[1] Motivated by this mainstream interacting-dark-sector result, we present a
conservative mapping between the MetaTime v36.0 latency/execution language and the standard
momentum-exchange (drag) formalism used in Boltzmann codes. In PRD-safe terms, “latency” is
treated 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 effective
latency 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 claims
are conceptual and reduce to ΛCDM in the zero-coupling limit.
