Design Blueprint: Thermal Load Budget and Helium-3 Circulation Requirement for a Dilution Refrigerator Stage Reaching Ten Millikelvin

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24147704): This paper presents a computed design for a dilution refrigerator stage intended for millikelvin refrigeration, with its performance, resource budgets and margins derived from stated assumptions rather than asserted. The headline results are: heat conducted down the supports of 3.6 microwatt; heat conducted along the wiring loom of 0.384 microwatt; radiative load from the still-temperature shield 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.
