Architecture

• Use Onion architecture

  • Dependencies go inwards. That is, the Core domain doesn't know about outside layers

• Use pipeline model to implement workflows/use-cases/stories

  • Business logic makes decisions
  • IO does storage with minimal logic
  • Keep Business logic and IO separate

• Keep IO at edges

(*
An exercise in modeling. Users can be verified or banned. A user can be banned only if their username is "offensive".

We assume the Onion architecture. Modules `User` and `Verification` belong to the model. Module `UserVerification`
belongs to the application layer. Data access layer is omitted completely; it should be fairly trivial.

Note that the verified/banned aspect of a user is modeled "externally" to the notion of user itself. In particular,
there are no "aggregates" below which combine all aspects of a user.
