function convertSignalPlaceholders(self)
% CONVERTSIGNALPLACEHOLDERS Validate Signal class chain consistency
%
% This function examines Signal classes and validates they are consistent
% with the routing matrix. Since Signal extends OpenClass, all Signal
% objects are open classes by default. This function validates that any
% class-switching involving signals maintains chain consistency.
%
% Note: Signal classes are always open (extend OpenClass). For class-switching
% from closed classes to signals, the signal must be in the same chain.
