Thanks, that makes sense, so the force exit procedure is fairly similar to lightning channels.

1 more question: if the 2nd party isn't online when a hedgehog channel is created where is the information about state changes stored and how can party 2 access it once it comes online?

Thank you for the great work you've been doing!

please correct me if I'm wrong, but don't you need BOTH parties to be online at all times once their shared multisig is funded in case one of the parties tries to exit with invalid state?
