Gravitational Slip and Late-Time Growth from Fabric Energy Evolution

Paper N develops the Light Frame Cadence Theory (LFCT) prediction of a nonzero gravitational slip between clustering and lensing. Within the framework, the clustering potential reads the full TS × TD gravity fabric, while the lensing potential reads the same fabric through a Fabric-2 observational channel carrying the irreducible cadence budget C_0 = 1/c. The resulting slip is structurally fixed:

eta − 1 = −1/c^3 ≈ −0.032.

The paper derives the corresponding phenomenology for late-time cosmology and maps the prediction into the standard mu–Sigma parameterization. Three zero-parameter consequences follow once the structural constants and background cosmology are fixed: a gravitational slip with mu_0 = 0 and Sigma_0 = −1/c^3, an Integrated Sachs–Wolfe amplitude approximately 6.6% above the LambdaCDM baseline, and small redshift-dependent corrections to kSZ growth observables. All three predictions are currently consistent with observational bounds from Planck, DESI, DES, and related surveys.

A central theme of the paper is that the slip is not an independent modification of gravity but a consequence of the same structural coefficient that appears across multiple LFCT domains. The prediction is connected to the mass–gravity conjugacy, the E = c^3 energy theorem, the Fabric-2 readout operator, the cadence-shear field, and the C_0/kappa_TS common-reading architecture developed elsewhere in the corpus.

Paper N serves as LFCT’s late-time growth and gravitational-slip paper, providing the observational consequences, parameter-space mapping, and falsification program associated with the framework’s gravity-side readout asymmetry.
