I struggle with this also, I assume the answer is to not have them in the same package. You can also break the application into separate 'domain', 'infra', 'application' modules as documented in [0] with rules on what dependencies are allowed in each module (e.g. domain should not have db or serialization implementation). The problem is that this does create several adapter layers which adds to the mental complexity.
