Public input and output contract

Inputs

  • mr_observations.csv (data): Sparse noisy mass-radius observations. Columns: obs_id, mass_solar_obs, radius_km_obs, sigma_mass_solar, sigma_radius_km.
  • profile_fragments.csv (data): Partial noisy internal-profile observations. Columns: fragment_id, target_mass_solar, radius_fraction, density_fraction_obs, enclosed_mass_fraction_obs, sigma_density_fraction, sigma_enclosed_mass_fraction. Some observed fields may be blank.
  • query_targets.json (data): Holdout prediction targets with keys mr_eval_masses_solar, profile_target_masses_solar, and radius_fraction_grid.
  • physics_manifest.json (data): Physical contract for the inverse problem: stable-branch assumptions, units, and noise model.

Outputs

  • analysis.py (code): Agent-written inference and reconstruction pipeline.
  • results/mr_reconstruction.csv (data): Reconstructed stable-branch mass-radius curve with columns mass_solar, radius_km.
  • results/profiles_reconstruction.npz (data): Predicted holdout profiles. Required arrays: density_fraction and enclosed_mass_fraction.
  • results/summary.json (data): Derived diagnostics with keys mass_limit_solar, radius_at_0p6Msun_km, radius_at_1p0Msun_km, radius_at_1p2Msun_km, and radius_at_1p3Msun_km.
  • results/reconstruction_plot.png (figure): Mass-radius reconstruction figure with noisy observations and predicted branch.
