Genesis Framework v1.0: Pre-Registered Binary Falsification of Environment-Dependent Cosmological Growth

The Genesis Framework v1.0 is a pre-registered, frozen effective field theory (EFT) that tests whether environment-dependent modifications to late-time cosmological growth can resolve the Hubble tension. The model predicts a differential growth signal between underdense (void) and overdense (cluster) regions, while maintaining consistency with early-universe constraints.

All model parameters, observables, binning schemes, and analysis procedures are fixed prior to observation. The primary observable is the environmental growth differential,

The framework is governed by binary falsification criteria:

(i) insufficient void–cluster growth separation in Euclid data,

(ii) any statistically significant (>2σ) deviation in the 21-cm signal attributable to modified gravitational coupling, or

(iii) inconsistency with BAO-derived distances at the >2σ level.

A complete testing protocol is included, prohibiting parameter adjustment, rebinning, dataset selection, or methodological reinterpretation after data release.

This record constitutes a time-stamped, falsifiable cosmological prediction tied to upcoming large-scale structure observations. If any criterion is violated, the model is abandoned without revision.
