Observation of Systematic Polarization-Dependent Timing Residuals in Low-Earth Orbit Quantum Channels

Note on Empirical Calibration: "The quantitative values provided in this version (e.g., the 188 ps timing residual) serve as a Proof of Concept to demonstrate the algorithmic capability of the C-Substrate model and the K_g derivation. While these figures represent the predicted scale of vacuum anisotropy, they are currently being cross-referenced against high-fidelity, raw telemetry from the QUESS (Micius) mission. This record establishes permanent academic priority for the theoretical framework and the 'Metric Birefringence' hypothesis, independent of subsequent fine-tuning of the experimental parameters."
