      on 2026-07-27. The title and contact in the original name the platform vendor (Opendatasoft), not the operator
      of this deployment; this overlay attributes the surface to UK Power Networks without mutating the harvested
      document.

  update:
    x-apievangelist-undeclared-responses:
      note: Two statuses the running service genuinely returns are absent from every operation in this document.
        Documented in errors/uk-power-networks-problem-types.yml rather than injected into the contract.
      '403': ForbiddenAccess — per-dataset permission gate covering 99 of 136 datasets.
      '404': NotFoundResource — unknown dataset_id.
- target: $.paths['/catalog/datasets/{dataset_id}/records'].get
  update:
    x-apievangelist-precondition: Read the parent dataset field schema via getDataset before composing any select,
      where, group_by or order_by clause. Field names are per-dataset; an unknown field yields HTTP 400 ODSQLError.
    x-apievangelist-bulk-alternative: exportRecords — uncapped, and the documented route for anything beyond the
      offset+limit < 10000 window.
- target: $.components.securitySchemes.apikey
  update:
    x-apievangelist-warning: The key travels in the query string, so it will appear in server logs, browser history
      and Referer headers. Treat it as a low-sensitivity read credential and rotate it from the account page rather
      than embedding it in shared URLs.
    x-apievangelist-key-url: https://ukpowernetworks.opendatasoft.com/account/api-keys/
    x-apievangelist-sdk-convention: The official Python client reads it from a UKPN_API_KEY environment variable.
