Design Blueprint: A Heliocentric Laser Interferometer with Five-Million-Kilometre Arms Tuned to the Spectral Turnover of a Torsion-Regulated Bounce

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24142336): This paper presents a space mission design, computed from stated assumptions and not measured, built to measure one quantity: the characteristic strain of the bounce background at 3 millihertz, for which the design case adopts 2.40e-21 in characteristic strain. 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.
