Builds a Twilio-backed SMS service that mirrors iOFFICE production and shows the actual decisions: abstracting effects as an F, implementing business logic pure and testable with a state monad test harness, running effects with a ZIO task, talking to the DB via Doobie transact and serving routes with HTTP4s routes. Scalaz/Cats typeclasses constrain F, logging is provided by lager/log4j, error recovery uses MonadError/ recover, tests run against the simulated world, and the wired app runs end to end.
