We carried out a fully transparent numerical falsification attempt for a minimal local-proxy isomorphism: host stellar mass, treated as a local witness-density surrogate, was tested for a detectable effect on implied H0 mean and scatter. Across tests H0–H4 we find null results at conventional significance, constraining the simplest local-mass-driven stiffness model. Crucially, these null results motivated the search for a more general mechanism which nullifies local relations. The demonstrated insensitivity of the emergent metric to local witness density forces a pivot from local environmental couplings to a global operator. Consequently, we derived a general Genesis redshift mechanism in which redshift is a ratio of global lapse factors, 1+z = Lobs/Lemit, driven by the evolution of the Observer’s complexity. We showed that a generic information-theoretic “learning curve” (logarithmic accumulation crossing to linear maintenance) yields a smooth baseline expansion history (H ∼ α/τ + β) that naturally reproduces late-time acceleration. Supplementary tests reinforced this minimal global view by disfavoring “baroque” extensions: the data rejected a jerk-aligned variance phase transition (GVTT) and showed no evidence for calibration drift or modified growth. The resulting cosmological model is one of high parsimony: a universe expanding not due to dark energy or local forces, but as the consequence of the Observer’s complexity growth.
