Phase-Flow Coherence from Finite Distinguishability Closure (PFC v6.1)

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…
