The BBN Breakthrough · Paper 23
Paper 23 v2.0 supports Oppenheimer-Snyder perturbation theory, scalar bridge operators, the spectral-index chain, and R4/FIRAS auditing.
If the theory is correct, the math will just work.
Paper 23 — Primordial Perturbation Theory
Builds the primordial perturbation theory program on the Oppenheimer-Snyder interior, deriving the closed-FRW perturbation equations, constructing explicit boundary-to-bulk bridge operators, and reporting the scalar spectral-index chain. The v2.0 support bundle adds R4/FIRAS dependency auditing and confirms the active Paper 23 spectral-index calculation is not R4-dependent.
This paper is grouped in the The BBN Breakthrough era and kept aligned to the live bridge map terminology used across the public site.
