Do they make 'double' rope? I know there is the internal structure and the external protection but I'm thinking something more like two independent internal structures such that if one fails the other can still handle load, and just as importantly it's obvious when the rope is in this state so nobody starts with it that way - it's only as the last line of defense.

I don't know of anything quite like what you're describing, but there are "half" or "twin" ropes, which are meant to be used as a pair. They're each thinner and lighter than ropes rated as "single" ropes, but together are considered as strong.
