✓ Major Validation: NeuroResonance data provides the first direct experimental confirmation of CFE substrate predictions. The 101 resonance peaks across 12 orders of magnitude (0.02-20 THz) demonstrate that tubulin possesses the rich electromagnetic resonance structure required for quantum-coherent consciousness substrates.

✓ Validation Success: All 7 computational experiments confirmed CFE predictions. Phase transition behavior, multiplicative necessity, and spatial field diffusion reproduced with high fidelity.
