Design Blueprint: Hold Time of a Cryogenic Dewar for Quantum Sensors: Multilayer Insulation Load, Neck Conduction and Boil-Off Budget

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24147840): This paper presents a computed design for a sensor Dewar intended for cryogenic storage and transport, with its performance, resource budgets and margins derived from stated assumptions rather than asserted. The headline results are: heat load through the multilayer insulation of 0.044 W; heat conducted down the neck of 0.0801 W; hold time with the sensor powered of 2.92 days; hold time with the s 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.
