Model 1 Residual-Response Scale-Window Growth Audit for the 7-phi Framework

Description / Abstract: This dataset accompanies the updated technical note Residual Scalar Response and Late-Time Growth Suppression in the 7-phi Framework. It contains a first-pass audit of a scale-windowed Model 1 residual-response growth-suppression extension. Model 1 starts from the entropy response function: mu (u) = u / (1 + u) with residual inactive response: 1 - mu (u) = 1 / (1 + u). The effective growth response is modeled as: Gₑff (k, z) = G 1 - epsilonS B (k) / (1 + u0 (1 + z) ᵖ) where the scale window is: B (k) = k² / (k² + kₜ²). The package includes the updated PDF note, LaTeX source, CSV outputs, RSD audit results, S8 sanity check, scale-window scan, plots, and README. A first scale-window approximation using the S8 scale k8 ≈ 0. 125 h/Mpc finds that the useful Model 1 signal survives after scale protection is introduced. The best scanned scale-windowed case gives approximately: kₜ = 0. 15 h/MpcB (k8) = 0. 4098epsilonS = 0. 36etaₑff (0) ≈ -0. 098S8 ≈ 0. 803Delta chi2 ≈ -6. 21 relative to Model 0 in an illustrative uncorrelated RSD f sigma 8 audit. This dataset is exploratory. It does not use a full covariance matrix, does not implement the model in CLASS/CAMB, and does not perform a joint fit with CMB, BAO, SNe, weak lensing, or CMB lensing data. The result should be interpreted as an audit-level indication that scale-windowed Model 1 remains worth harder testing.
