Information-Based Gravity / Modified Growth (IBC/MG v8.6)
Abstract
We present a minimal, reproducible growth-only, late-time modification implemented in hi_class/CLASS at a single insertion point (the first Newtonian-gauge ψ Einstein–Poisson closure). We validate tier-1 null tests (fixed ΛCDM background, unchanged early-time anchors) and report growth-sector signatures (ΔP/P, σ8(z), and an E_G(z) prediction). We also provide a dynamic relaxation toy model whose response converges to the same late-time gate and is numerically consistent with the static baseline.
