Model 1 Residual-Response Growth Suppression and RSD Audit for the 7-phi Framework

Description / Abstract: This dataset accompanies the technical note Residual Scalar Response and Late-Time Growth Suppression in the 7-phi Framework. It contains an updated Model 1 audit package testing a residual-response growth-suppression extension of the 7-phi dark-sector framework. 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) using a scale-averaged first-pass approximation with B (k) = 1. The package includes the updated technical note PDF, LaTeX source, CSV outputs, S8 suppression scan, f sigma 8 selected-case outputs, an illustrative RSD f sigma 8 audit, plots, and README. The first-pass RSD comparison finds that Model 1 can improve the uncorrelated chi-square relative to Model 0 in this illustrative dataset. The best scanned case gives approximately: epsilonS = 0. 14, u0 = 0. 5, p = 1. 5 with: chi2Model0 = 14. 76 and: chi2Model1 = 8. 58 corresponding to: Delta chi2 ≈ -6. 18. This result should be interpreted as an audit-level indication only. The comparison does not include a full covariance matrix, a complete CLASS/CAMB Boltzmann implementation, or a joint fit with BAO, SNe, CMB, weak lensing, and CMB lensing data. Model 1 remains a motivated candidate extension requiring stronger tests. DISCLAIMER Generative AI was used to assist with literature screening / coding support / draft language revision.
