Mirror-to-Baryonic Geometric Energy Ratio

Theorem 105 identifies a distinguished dimensionless ratio that emerges directly from the Q5 architecture. The value arises from previously established structural quantities, including the Q5 symmetry order, the dual-fibre transport geometry, boundary normalization factors, triadic multiplicities, and the 161/160 Möbius closure correction. The significance of the result is that the numerical value is not obtained through parameter fitting or external calibration. Every factor entering the construction is inherited from earlier geometric and transport structures within the framework. The ratio is therefore forced by the architecture itself rather than introduced phenomenologically. At the structural level, the derivation is exact. The theorem establishes the existence of a fixed geometric ratio naturally generated by Q5 transport architecture. Interpretation of this ratio as a mirror-to-baryonic energy relation remains conditional upon later closure results that connect the geometric construction to physical observables. Status: Structural derivation solid. Physical interpretation is conditional.
