On eligibility, not the most fun topic, but you will want to put in a clause that countries that are banned from trading with the NATO/USA countries cannot function as council members such as North Korea, Russia, Belarus etc… as I think it will be seen as problematic if they sign a contract as council members while being in an area that does not allow such interference. You refer to the state of california later on, so I’d say this is a required extra caveat to add. Up to you.
