Model 1 Residual-Response Growth Audit with RSD, S8, Scale-Window, and CMB-Lensing Checks 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 residual-response Model 1 growth-suppression extension. Model 1 starts from the entropy response function: mu (u) = u / (1 + u) and identifies the residual inactive response fraction as: 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) with optional scale protection through: 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, CMB-lensing amplitude check, plots, and README. The best first-pass residual-response case improves the illustrative uncorrelated RSD f sigma 8 comparison relative to Model 0, shifts S8 from approximately 0. 834 to approximately 0. 805, and gives a CMB-lensing-style amplitude sigma8 Omegaₘ⁰. 25 approximately equal to 0. 588, close to the Planck-lensing reference value 0. 589 +/- 0. 020. A scale-windowed version also preserves the useful signal in a k8-effective approximation. 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 likelihood fit with CMB, BAO, SNe, weak lensing, CMB lensing, or RSD data. The result should be interpreted as an audit-level indication that Model 1 deserves harder testing.
