Small quibble, I really like inverting the (business logic) –> (persistence) dependency. That way your business logic drives everything, which aligns with your point about the app being "logic with an HTTP interface." Agree wholeheartedly with the rest.

Thanks! Are you suggesting business logic depends on persistence or persistence depends on business logic? How is the second option possible?

The second option is possible if you declare an abstract dependency (preferably just a contract like an interface) and make your persistence layer implement it. I highly recommend "Clean Architecture" if you'd like to learn more about that approach.
