First it would be handy if the layer would be in the messages "This layer can't abut or partially overlap between subcells" and "Can't overlap those layers". I can't find which layers give this error.

I have developed an annotation tool which annotates a magic .tech file to always display all potential layers of that rule

This is an annotated tech file you can use directly:
