Design Blueprint: Regolith Berm Shielding for a Surface Habitat Sized Against Solar Particle Events and Galactic Cosmic Rays

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24189157): This study sizes regolith berm shielding for a reference surface habitat: an areal density of 36 grams per square centimetre, a thickness of 0.24 metres at the stated bulk density, reduces a solar particle event dose proxy by a factor of 20, while the same berm reduces a galactic cosmic ray dose proxy by only a factor of 2.22. Covering 245 square metres requires 59 cubic metres, about 88 tonnes, of regolith. Sizing follows from computed radiation and regolith budgets derived in the study. This is a computed study with no targeting or weapon application. The work is simulated and computed from stated assumptions, not measured. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json.
