Why Matter Won: The Missing Half of the Universe's Causal Organisation

Natural Evolution of Actuality (NEA) begins with independently lawful abstract parentalresponsibilities M and F and primitive consequential joining Ω. Its developed fermionicconstruction contains complementary past-facing and future-facing causal-transport responsibilities whose complete spinorial return is Uf (2π) = −I and Uf (4π) = I. A selectedaccessibility effect produces the source-owned orientation excess Aacc = (1 − ε)/(1 + ε) froma balanced complete carrier. This paper reconstructs and strengthens the mathematicaldistinction between such asymmetric access and the actual production or retention of unequal matter–antimatter populations. An exact charge–chirality separation theorem showsthat arbitrary access bias alone leaves an independent signed species label balanced. Acorrelated two-sector state yields the conditional readout ⟨B⟩acc = cAacc while retaining⟨B⟩complete = 0; a charge-preservation theorem rules out net charge production by conserving transport. We then prove a selection-independent two-state actualisation identity andexhibit one NEA-compatible selected conversion law, dn+1 = (1−s)dn +sδ, with δ = ζcAacc.Its finite-time solution is derived, generalised to varying source conditions, and realisedby an explicit completely positive trace-preserving quantum channel. A charge-balancedevent-register dilation and an integer-valued finite-population model show how individualtransitions, their expectations and append-only consequential Records can be distinguished.We retain the original 4π holonomy, the separate chiral and species-label exchanges, andthe No Silent Erasure principle. Finally, we derive the algebraic distinction between themodel’s signed population fraction and the cosmological baryon-to-photon observable. Theresult is a self-contained constructive existence study of lawful population actualisation, nota claim that the primordial laws uniquely select the channel, nor a quantitative predictionof the measured cosmic baryon abundance.
