Paper 28 — The Primordial Spectral Index
Builds the main theorem scaffold for the primordial scalar power spectrum and derives the conditional zero-fit prediction n_s = 0.9639. Key ingredients include the Hawking Accumulation Theorem, the DtN Boundary Hessian identification on the Painlevé-Gullstrand collar, and the Boundary Fixed-Point Principle, along with a proper-time formation-clock theorem that eases the JWST "impossible galaxy" tension.
