    # Note: In a real app, this check might happen per-request or refresh periodically.
    # For MVP, we check on startup (or default to registered but checked internally).
    # We will register it as a "Secondary" guard or chain it.
    # For simplicity: We replace the InputGuard OR Chain them.
    # Let's Chain: The Coordinator currently supports one input guard.
    # We will make NeuralGuard WRAP the InputGuard (PatternComposite) or specific Logic?
    # Simple approach: Coordinator holds a list. Only 1 for now.
    # Let's add it as a separate property for now to minimal change.
