Reproducibility dataset for "A Structural Morphology Audit of Mass-Loss Regimes in Close-In Exoplanets"

This dataset contains the curated benchmark sample underlying the manuscript A Structural Morphology Audit of Mass-Loss Regimes in Close-In Exoplanets. It records the adopted planetary parameters, derived quantities, and observational morphology labels used in the paper’s benchmark comparisons of close-in exoplanet mass-loss regimes. The dataset includes planetary mass, radius, orbital period, mean density, escape velocity, the dimensionless structural coordinate SS, morphology classification, and provenance for both adopted parameters and morphology labels. The benchmark is intentionally small and data-limited rather than population-complete, and is designed for a controlled comparison among well-studied divergence cases.
