Design Blueprint: Spin-Polarised Shield Panel: Radiation Attenuation and Mass Trade for Crewed Transit Vehicles

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24123344): The device is a hull panel of hydrogen-rich polymer whose hydrogen nuclei are maintained in a spin-polarised state, adding a stated torsion-coupled increment to the panel's mass attenuation coefficient for the cosmic-ray dose proxy used in this study. 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. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
