The Fermionic Matter Sub-Programme

Fermionic structure on supplied carriers, with every conditional bridge explicit.

Overview

The bosonic spectral stratification ($a_2 \to$ gravity, $a_4 \to$ Yang–Mills) supplies a gauge–gravity architecture for a supplied compact structure group. Fermions, chirality, hypercharge, and the three-generation structure are not covered by that bosonic synthesis. The fermionic matter sub-programme answers: do they also arise from the projective framework, and which bridges must be supplied?

The answer established by Q14 is stratified and conditional. On a supplied Heisenberg carrier and conditional on the [H-L] Lorentzian geometry, fermions arise as the spinorial face of the Weil module $V_\rho$ after Lorentzian complexification of its metaplectic lift. The carrier and spatial limit are not selected or established by the admissibility axioms. Relative to these inputs, chirality and the $V-A$ structure arise from the projective endomorphism $E_\Pi$. Hypercharge trace constraints are structural, but rigidity of the weights requires a supplied three-dimensional colour module. The generation factor requires a supplied rank-three carrier. Also not forced at the current stratum is the independent fermionic weak doublet: the tensor functors of the spinor bundle produce Lorentz-typed gauge-sector data, and the two deposited candidates for the multiplicity carrier $M_L \simeq \mathbb{C}^2$ are closed by the exact obstructions of the NSR no-go note; its realisation is an explicitly architectural open frontier.

Scope statement. The spinor bundle and chiral selection are settled relative to the supplied Heisenberg carrier and conditional [H-L] geometry. Hypercharge rigidity and generation multiplicity retain the colour-module and rank-three-carrier hypotheses respectively. The mass spectrum, Yukawa couplings, and CKM/PMNS mixing matrices remain open.
