DELETE /api/v2/users/{id} breaking historical interaction data?

We’re trying to clean up a test user via the API, but I’m worried about data integrity. If I send a simple DELETE request to /api/v2/users/{id} using our standard OAuth token, does Genesys actually hard-delete the record? Or does it just disable the user? I need to know if the historical interactions remain linked to that user ID or if we lose the audit trail. We’ve seen some weird null references in our reports when users are removed, so I want to be sure before I run a script. The docs aren’t super clear on the retention behavior for deleted entities.
