Paper 12 — The Baryon Dictionary Principle
Responds to an internal kill-shot audit by replacing the ad hoc baryon fraction with the Baryon Dictionary Principle, which identifies baryons as the gauge-coupled subset of Oppenheimer-Snyder dust and fixes f_b = 2γ/x. The paper also introduces the discrete α-ladder and argues that α = 1 is the unique projection scaling consistent with the observed deuterium abundance.
