Design Blueprint: Torsion Gyroscope: Drift Budget for an Inertial Reference Unit Using a Spin-Polarised Rotor

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24123436): The device is a single-axis gyroscope whose rotor is spin-polarised, so that the torsion field of the rotor's own aligned spin population stiffens its response to disturbance torques that would otherwise appear as drift. 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.
