Physics-Constrained Kinematic Anomalies in Low-Periapsis Lunar Orbits

EMPRESS (Empirical Motion Physics Reproducibility and Statistical Evaluation System) is a physics-constrained kinematic dataset designed for independent validation of orbital motion under extreme low-altitude regimes. This release contains reconstructed trajectory outputs, summary statistics, and anomaly classifications derived from a large-scale audit of low-periapsis lunar orbital paths. The dataset includes kinematic reconstructions generated using deterministic physics constraints, uncertainty propagation consistent with the Guide to the Expression of Uncertainty in Measurement (GUM), and sigma-based statistical evaluation thresholds. Each trajectory was evaluated for temporal coherence, velocity consistency, and acceleration plausibility, enabling the identification of statistically significant deviations from expected Newtonian behavior. This dataset supports reproducibility of results reported in the accompanying manuscript submitted to Surgery Today and is intended for reuse in orbital dynamics validation, navigation reliability assessment, and the development of standardized verification frameworks for high-precision kinematic telemetry. All files are provided in non-proprietary formats to facilitate independent analysis and cross-platform reuse.
