OBSGRAPH validation data and source code for early survivor/ejector classification in planetary scattering simulations

This record contains supplementary validation material supporting the manuscript “OBSGRAPH: An Observable-Graph Diagnostic for Early Survivor/Ejector Classification in Planetary Scattering Simulations”. The archive includes source code, validation CSV files, generated reports, checksums, and reproducibility material for the OBSGRAPH observable-graph diagnostic. The study evaluates early survivor/ejector classification in Newtonian planetary scattering simulations by comparing raw score predictions, grammar-gated locks, hard confirmation locks, and simple baseline rules. The deposited material is intended to support reproducibility and independent inspection of the numerical results reported in the manuscript submitted to Astronomy and Computing. No external observational datasets were used.
