Design Blueprint: A Communication Terminal at the Solar Gravitational Lens Focal Line: Lens Gain, Pointing Tolerance and Data Rate for a One-Watt Laser at Six Hundred and Fifty Astronomical Units

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24169045): This paper presents a design study of a system whose operating principle is Amplification by the Sun's gravitational lens at its focal line beyond 550 AU. The sizing is computed from stated assumptions, with every headline quantity produced by the deposited calculation script. The headline results are: lens gain dB = 90; photons per s = 8.058e+04; rate bps = 4.029e+04; received W = 1.033e-14. The study is simulated and computed, not measured, and the design is labelled SIMULATED, NOT MEASURED. Where the computed outcome is unfavourable to the concept, that outcome is stated as the result rather than softened: the purpose of the study is to establish, from the governing relations, what a system of this kind can deliver at the stated distance, temperature, or scale, what it costs in mass, area or power, and which assumption controls the answer. 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.
