Design Blueprint: A Transit-Beacon Receiver: Link Budget, Sensitivity and Acquisition Behaviour for Phase-Step Beacon Signals

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24129848): A beacon organised by the transit law's phase steps is only as useful as the receiver that can find it: a narrowband, structured signal that must be acquired against Doppler uncertainty and noise. 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.
