All the example use cases seem to be for non business critical stuff. Is this being sold as a tool that I could use for.. say.. persistent workflows for customer payments? Say I needed to take payment, and make sure that a ticket is reserved using a 3rd party api once the payment is successfully processed, refund the payment if there's some kind of problem, and then I need to send a confirmation email. Can I store and query state on the workflow? In my code can I `await` the completion of a workflow and get a result?
