iv
is not used in any event, i.e. this constraint is just dead. If I understand it correctly, src
is the IV where we have a length constraint. Is this constraint sufficient?

We don't have a predefined predicate unique
... It would maybe be possible to add it to the REQUIRES
section, then we need a corresponding part in the ENSURES
section for a class that can generate an IV
