EXPERIMENTAL PROOF: THE SHG RESONANCE SHIFT

"Before you build the machine, you must master the boundary. Before you write to the physical universe, you must compile the state transition rules."

if Xi_scalar > 0.9:
    rule = "sigma_upconversion [High-Coherence Node]"
elif Xi_scalar > 0.1:
    rule = "sigma_phase_shift [Boundary Transition]"
else:
    rule = "sigma_mismatch_decay [State Leakage]"
