Structural 9CG Fermion Coefficients and an Internal PMNS Parametrization in the TTOE Framework

This manuscript gives a bounded public formulation of the fermion/PMNS block of the TTOE framework. The 9CG table is presented as a Coxeter/branching-motivated selection of rational coefficients along the chain E8 -> E6 -> D5 -> A4 -> G_SM. These coefficients are compared with a historical Clebsch/GUT target table CG_req, which is treated as an external input rather than as a mass table derived from E8. A finite-table audit included in the package supports only a local rarity statement inside the same formal grammar, not a global p-value and not a derivation of fermion masses. The PMNS part records an internal parametrization and a type-I seesaw mass scale under the explicit input Y_nu=1. The reactor angle sin^2(theta_13)=19/900 is presented as a structural selection inside a finite class; theta_12 and theta_23 remain outside current experimental precision. The CKM sector is outside the scope of this manuscript and remains open/not audited in the active canon.
