This paper gives the physical reading layer of the FDC framework, connecting finite distinguishability and internal update constraints to complex amplitudes, Born-type weighting, Schrödinger-type update, and phase-flow coherence. The broader program also reports non-fitted structural readouts near quantities such as - α⁻¹ ≈ 137.035999,- proton/electron mass ratio ≈ 1836.152673,- muon/electron mass ratio ≈ 206.768283,- tau/electron mass ratio ≈ 3477.23, together with Hubble-scale and MOND-type galactic readouts developed in companion papers. PFC does not itself fit these constants. Its role is to provide the physical reading layer by asking which amplitude and update structures survive when the FDC closure grammar is interpreted dynamically. PFC does not treat quantum mechanics as an empirical target to be fitted. Instead, it studies how complex amplitudes, Born-type weighting, Schrödinger-type update, and phase-flow coherence can be read as physical manifestations of finite distinguishability and internal update constraints. Within the broader MOF–FDC–PFC–SCR–AOH program: - MOF provides the eliminative ontological foundation.- FDC provides the formal finite-distinguishability closure framework.- PFC provides the physical reading layer.- SCR records structural constant readouts.- AOH applies the same grammar to cosmological and galactic-scale phenomena. Readers interested in the formal origin of the assumptions used here should consult FDC. Readers interested in numerical structural readouts should consult SCR. Readers interested in Hubble-scale and galactic-scale applications should consult AOH. This paper should be read as a conditional physical reading layer built on FDC, not as an empirical fit to quantum mechanics.
