Design Blueprint: A Network of Optical Lattice Clocks for Ultralight Dark Matter and Relativistic Geodesy: Coupling Reach Computed from Clock Instability

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24150304): Twelve optical lattice clocks, each with fractional instability 1e-16 per root second averaging to a 3e-19 floor, are designed as a correlated network. The 66 pairwise comparisons suppress uncorrelated clock noise, giving a detectable oscillating fractional-frequency amplitude of 3.69e-20 for an ultralight scalar field of mass 1e-17 eV over its 4.14e+08 second coherence time, corresponding under t 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.
