  Captures the API Evangelist enrichment round of 2026-07-27 as overlay actions
  rather than mutating the harvested spec. Every value below is either an
  artifact cross-reference or something verified live against
  https://spenergynetworks.opendatasoft.com/api/explore/v2.1 on that date —
  notably the 403 ForbiddenAccess response, which the running service returns
  but the published contract does not declare.

        Read-only contract — GET only, therefore every operation is safe and
        idempotent. Catalogue is anonymous; most datasets refuse /records
        anonymously with 403 ForbiddenAccess.

        Frequently 403 anonymously. In a 100-dataset probe on 2026-07-27, 13
        datasets returned 200 and 87 returned 403 ForbiddenAccess. Handle 403 as
        an expected per-dataset outcome, not an exception.
      responses:
        '403':
          description: >-
            Forbidden — the dataset's records are not readable by the calling
            identity. Returned live by the service but not declared in the
            published contract. Body: {"error_code": "ForbiddenAccess",
            "message": "You don't have permission to access the requested
            resource"}.
        '404':
          description: >-
            Not found — the dataset_id does not exist on this domain. Returned
            live but not declared in the published contract. Body:
            {"error_code": "NotFoundResource", "message": "The requested dataset
            <id> does not exist."}.
