Dear @reverseacid

Very interesting this topic.
I think that both of you have to know very well how the contract is established and that part stops complying with it because the responsibility is individual but both are involved.

If only two are involved, how to know which of the two is including it if both say they are doing well.
Then, in my opinion, there should be a mediator if either one claims that the other is not complying with the contract.

Well that's my humble opinion.
