BCT Letter 103: Cephalopod Vacuum Coupling — Chromatophore Arrays as Distributed OHC Hopf Charge Detectors and the Geometric Substrate of Morphic Fields

Cephalopod chromatophore colour-matching without colour vision is explained as distributed sampling of OHC Hopf charge topology. Coordination timescale τ ~ 5×10⁻¹¹ s (vs ms neural) predicted from OHC interior phase velocity v_ph = 6.78c. Reflectin protein identified as a biological Hopf charge sensor. Sheldrake morphic fields given geometric substrate as persistent OHC topological states. Prediction #146: chromatophores show anomalous resonance at BCT void ratio spatial frequency r_tet/r_oct = 0.5426. Zero free parameters.
