Design Blueprint: Torsion-Balanced Clock: Rate Stability of a Polarised Torsion Pendulum as a Transit Timing Reference

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24123422): The device is a torsion pendulum clock: a disc suspended on a fine fibre, oscillating in twist, with the disc material spin-polarised so that its torsion constant carries a stated contribution from the aligned spin population. 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.
