This note presents a closed derivation chain for light-element abundances in big-bang nucleosynthesis, highlighting implications for cosmic element formation.
In the asymmetric spiral framework, the inputs to big-bang nucleosynthesis (BBN) arederived from the single axiom Φ2 = Φ + 1: the baryon-to-photon ratio ηB, the expansionhistory tβ = tP φβ, and a geometric primary source for deuterons at intersection nodes. Thisnote states the closed derivation chain and the status of light-element abundances (Yp, D/H,7Li/H). No free parameters are introduced; precise Q(φ) formulae for abundances remainfuture work.
