      A record of documents the platform generated and handed over, retained as
      evidence of what

      was issued. `subject_type` says what kind of records an export covers, and

      how the request is authorised: there is no export permission of its own,
      so if you can see the

      records you can export them.

      Bulk loads of locations from an uploaded CSV. An import matches rows on

      doubling the population, and the import record is the audit trail for the
      whole load: the bulk
