"""
Coherence Telephone – Enhanced Earth–Moon FTL Test (FINAL)
v1.2 – December 2025
John Bollinger (@AlbusLux1)

Critical parameters discovered live:
J_coupling = 8.0  → perfect FTL comms
gamma      = 0.1  → long coherence time
mod_amplitude = 0.8 → strong, clear bits

One run. One number. Physics changes forever.
