The Sensory-Motor Coupling Wall

Three experiments returned null (5, 6, 9). All hit the same limitation: $\rho_{\text{sync}} \approx 0$ . The FFT convolution kernel integrates over the full grid — patterns are inherently internally driven. V15 motor channels, V17 signaling, V18 boundary gating all failed to break it. The wall is about agency: action-observation causal loops, not signal routing.

The architectural space has been exhausted. Breaking the wall requires a fundamentally different substrate.

Two walls, two breaks. The

\rho

wall (sensory-motor coupling) falls to V20's protocell agency (

\rho_{\text{sync}} = 0.21

). The decomposability wall falls to V27's MLP head (

\intinfo = 0.245

). Both are architectural — neither can be overcome by more training, better targets, or richer environments.
