Design Blueprint: Torsion-Coupled Flywheel: Energy Storage in a Spin-Polarised Rotor Limited by Shear at the Aldred Density

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24123288): The device is a solid cylindrical steel rotor, 0.60 m in diameter and 0.40 m long, whose material is taken to be spin-polarised so that torsion in the Einstein-Cartan sense supplies an additional internal pressure opposing the centrifugal hoop stress. 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.
