Mathematical Content

Threshold-Dependent Admissibility [BBN.13]

The category of admissible endomorphisms on τ³ is not fixed but changes at each threshold crossing. The SA-i condition (η-winding preservation mod 3) applies only below the neutron threshold L_N (depth 3), where the C-sector has crossed its confinement coupling κ(C;3). Above L_N, at the baryogenesis threshold L_B (depth 2), the C-sector is deconfined and SA-i does not apply, permitting baryon number violation.

Baryogenesis Window [BBN.14]

B-violation is structurally permitted only in the window [L_B, L_N] (depths 2–3). Below L_N, SA-i locks in and baryon number is absolutely conserved. The window is finite and closed by confinement.

N_eff = 3 from Sector Exhaustion [BBN.19]

The three neutrino flavors correspond to the three non-gravitational generators {π, γ, η}. The ω-crossing is composite (ω = γ ∩ η), not independent, and α is gravitational. So N_eff = 3.

Dark Sector Closure [BBN.20]

The 5 generators exhaust all sectors. No additional generator exists to host a dark sector, so N_eff > 3 is structurally impossible.
