How does stepped_actions handle the state between steps? Does it persist to the DB after every single action to handle crash recovery, or is it more optimistic?

Good luck with the launch

The rails native way to do this is to track state in a db row and queuing “next step” jobs as the data changes. This can get verbose especially for smaller pass/fail workflows. However, I find this works better (not worse imo) in more complex workflows as the state is tracked, queryable, can be surfaced in UIs, and resumed “manually” in the event of an outage.
