The Fermionic Matter Sub-Programme

The fermionic matter sub-programme of the Cosmochrony corpus addresses a single central question: where do fermions, chirality, hypercharge, and three generations come from? The answer is that they are not postulated as external fields: they arise as the spinorial face of the admissible Weil module ${V_\rho}$, once its metaplectic Lie-algebraic structure is complexified by the Lorentzian metric established in the geometric branch. The structural chain is: \[ \Pi \Rightarrow F_n \simeq {V_\rho} \Rightarrow {\mathrm{Mp}}(2,\mathbb{R}) \Rightarrow \mathrm{mp}(2,\mathbb{R})_\mathbb{C} \simeq \mathfrak{sl}_2(\mathbb{C}) \rightsquigarrow {\mathrm{Spin}}(3,1) \simeq {\mathrm{SL}}(2,\mathbb{C}) \Rightarrow {\mathcal{S}_\Pi}. \] Three modular structural results are established in Q14: (A) the admissible spinor bundle ${\mathcal{S}_\Pi}$ reproduces the ${\mathrm{SU}}(2)_L \times {\mathrm{U}}(1)_Y$ electroweak bundle structure from tensor functors of ${\mathcal{S}_\Pi}$; (B) the projected Dirac operator ${D_{\Pi,g,A}}$ contains a canonical projective endomorphism ${E_\Pi}$ that enforces the $V-A$ chiral structure (conditional on Hypothesis 3.5) and whose $\gamma_5$-weighted $a_4$ coefficient imposes anomaly-cancellation constraints making hypercharge a spectral datum; (C) the saturation invariant $\sigma_c(n_3) = 3$ has a spinorial multiplicity reading yielding a gauge-singlet three-generation factor ${C^3_{\mathrm{gen}}}$. The colour-coupled quark sector is conditional on $[\mathrm{H\text{-}color}]$. Open deliverables are the explicit form of ${E_\Pi}$, the Yukawa sector, and the derivation of Hypothesis 3.5 from A1–A4.
