E8 to SO7 Invariant N=227 = 248-21 - Zero-Parameter Exact Identity

Zero-parameter exact identity from E8 Lie algebra. N = 248 - 21 = 227 where 248 = dim(E8) and 21 = Cartan + simple roots correction. Pure group theory, no fitted parameters, no S4D factor. This is part of the CCRT zero-parameter companion series to CCRT v1.1 one-parameter ansatz 10.5281/zenodo.21109251 v1.1. Formal definition: N=227 is an exact integer invariant.

Abstract

Zero-parameter exact identity from E8 Lie algebra. N = 248 - 21 = 227 where 248 = dim(E8) and 21 = Cartan + simple roots correction. Pure group theory, no fitted parameters, no S4D factor. This is part of the CCRT zero-parameter companion series to CCRT v1.1 one-parameter ansatz 10.5281/zenodo.21109251 v1.1. Formal definition: N=227 is an exact integer invariant.
