- <p>Radial Coherential Dynamics v12.0 — Module J — develops the full linear cosmological perturbation theory of RCD and demonstrates consistency with high-precision CMB data. Scalar perturbations (δC, Φ, Ψ) are derived in the Newtonian gauge, the coherence perturbation equation is obtained, and the coupled Einstein–coherence system is solved at first order.</p> <p>The key results include:</p> <p>• linearized δC evolution equation in Fourier space<br>• Φ = Ψ (no gravitational slip), consistent with Planck data<br>• suppressed coherence perturbations at recombination (O(α²))<br>• primary CMB anisotropies (ℓ > 30) unchanged at O(10⁻⁴)<br>• late-time ISW effect modified at O(√α)<br>• potential explanation of the low-ℓ anomaly<br>• growth function and σ₈ prediction consistent with lensing surveys<br>• full set of testable predictions for Planck, ACT, SPT, DESI, Euclid, and LiteBIRD</p> <p>RCD preserves the success of ΛCDM at early times while introducing small, observationally relevant modifications at late times that alleviate the Hubble and S₈ tensions. Module J completes the perturbation and CMB consistency sector of RCD v12.x.</p> <h1> </h1>
