This preprint derives a practical photon-transport law in the Aether Physics Model (APM) using Quantum Measurement Units (QMU). The goal is to supply the missing “propagation layer” that connects (i) emission geometry (electron holonomy and a cardioid photon-front interpretation) to (ii) reception dynamics (a finite photoelectric gate/coherence window that produces threshold and staircase behavior). The key kinematic anchor is the QMU identityc = Fq C, so one quantum moment has duration t = 1/Fqand advances a propagating front by one Compton length, r = c\, t = C. After n moments, the discrete propagation radius is thereforerₙ = nC. The inverse-square envelope is obtained as a discrete counting theorem rather than as a continuum axiom. The propagating front is modeled as a tiled shell whose area is counted in elements of size C². The ring added between successive moments follows the standard odd-integer shell-growth rule (the discrete analogue of circumference-driven growth), giving1 + ₊=₁^n-1 (2k+1) = n². Hence the effective transport area grows asA (n) = n² C² = rₙ². If the transported light content is conserved across the front, the areal intensity obeysI (rₙ) = L/A (n) = L/rₙ², which is the inverse-square envelope in purely QMU form. Cardioid photon geometry is incorporated as an angular weighting on solid angle, C () = (1+) / (4) with 0 1, normalized by C () \, d = 1. The combined transport law isI (rₙ, ) = (L/rₙ²) \, C (). Ensemble averaging over randomized photon axes restores apparent spherical symmetry, while single-emitter or aligned-axis regimes predict measurable cardioid anisotropy. The paper also unifies radiometric bookkeeping in QMU by showing that “intensity” and “irradiance” are complementary surface and volume views of the same transport content. Define the areal intensity unit and area quantum asIᵤnit = mₑ C Fq³ and Aᵤnit = C², so the transport unit isL = Iᵤnit Aᵤnit = mₑ C³ Fq³. Define the volumetric irradiance unit and volume quantum asEᵤnit = mₑ Fq³ and Vᵤnit = C³, so the same transport unit isL = Eᵤnit Vᵤnit = mₑ C³ Fq³. This identity acts as a consistency check and a bridge between wavefront propagation (area view) and localized interaction modeling in matter (volume view). Finally, the transport law is connected to the photoelectric gate/coherence framework: distance and angle scans change event rates through I (r, ) but do not shift gate landmarks (threshold integers or step spacing) unless the experimental arrangement perturbs the gate coherence itself. Practical falsifiability is emphasized via (1) distance-scan tests of the 1/n² rate law at fixed angle, and (2) angular scans of the cardioid form after correcting for instrument transfer functions.
