This paper develops an Aether Physics Model (APM) interpretation of the photonic Chern-insulator experiment of Chénier et al., which demonstrated quantized transverse drift of light in a synthetic frequency lattice. The experiment realizes a photonic analog of the quantum Hall effect without real charge carriers or applied magnetic fields. Within the APM expressed in Quantum Measurement Units (QMU), this response is interpreted as saturation of an empty Aether unit by photon angular-momentum transfer fronts. In the QMU framework, the fundamental propagation identity is $$A_u \,\mathrm{curl} = {F_q}^{2}{\lambda_C}^{2} = c^{2}.$$ This relation decomposes the electromagnetic propagation constant into rotational geometry ($A_u$) and torsional response (curl). Photons are interpreted as outward-curled transfer fronts that deliver structured angular momentum to the Aether substrate. When driven through a nontrivial holonomy cycle in a synthetic lattice, these photon fronts load the curl channel of an empty Aether unit and generate a quantized transverse drift. The Berry curvature measured in the photonic experiment is mapped to the inverse curl stiffness of the Aether unit, $$\Omega(\mathbf{k}) \longleftrightarrow \frac{1}{\mathrm{curl}} = \frac{A_u}{c^2}.$$ Under this correspondence, the experimentally measured Hall drift $$\delta x \approx \frac{\gamma \lambda}{2}\,\overline{\Omega}(\omega_L)$$ becomes $$\delta x \approx \frac{\gamma \lambda}{2}\frac{A_u}{c^2}.$$ This mapping explains why the observed drift magnitudes are consistent with MHz-scale shifts in the fiber-loop lattice. The integrated Chern number $$\nu = |\mathcal{C}|$$ is interpreted as the occupancy number of the Aether unit. The experimental plateau $$|\mathcal{C}| \approx 0.95 \pm 0.14$$ therefore corresponds to near-complete saturation of an empty Aether unit by photon angular-momentum fronts. The paper further connects the photonic response to the QMU angular-momentum scale $$h = m_e c \lambda_C = m_e F_q {\lambda_C}^{2},$$ showing that the Planck angular-momentum quantum resolves naturally into electron mass, quantum frequency, and Compton geometry. Within this framework, the photonic Chern-insulator platform becomes a laboratory probe of Aether-unit saturation. Three engineering extensions are proposed: 1. Integration of a rotating magnetic field detector to measure time-varying curl excitation in the fiber loop.2. Curl-threshold tests to search for localized gravity coupling driven by intense curl loading.3. Frequency-to-mass metrology in which topological occupancy serves as a primary mass standard. These extensions transform the photonic system from a condensed-matter analog simulator into a direct experimental testbed for Aether-unit dynamics and QMU-based metrology.
