This paper extends the Trinity/STO fine-structure derivation program by proposing a concentration–dispersion bridge between the space-face propagation scale c and the quantum action scale ℏ. Building on earlier work involving Hopf phase closure, diagonal record stability, and concentration–dispersion balance, the paper introduces a dimensionless balance ratio χ = C/D and proposes the bridge ansatz ℏ(χ) = ℏ₀χ¹ᐟ² and c(χ) = c₀χ⁻¹ᐟ². The resulting framework preserves ℏc, the fine-structure constant α (under fixed electromagnetic coupling structure), and the Planck mass mₚ, while generating systematic Planck-scale scalings for length, time, and energy. A numerical consistency test confirms the internal mathematical coherence of the proposed scaling relations. The paper does not claim a first-principles derivation of either c or ℏ, nor does it claim empirical evidence for variable physical constants. Rather, it presents a mathematically self-consistent bridge hypothesis motivated by geometric-mean concentration–dispersion balance within the Trinity/STO ontology of stable records. Future work focuses on determining whether the balance ratio χ can be derived from deeper closure principles or connected to measurable physical observables.
