A Late-Time Growth-Only Modification of Gravity with CMB-Lensing Consistency
Abstract
This version consolidates notation, parameter definitions, and interpretative scope following an independent referee-style audit. No changes to the numerical implementation or physical results are introduced. The background expansion remains fixed to ΛCDM, and the modification is confined to a single, well-defined insertion point in the perturbation equations. Canonical parameters (a_t = 0.5, p = 2) are used consistently throughout.
