      FIX A WRONG STAGING HOST. The published spec declares its staging server as
      https://api-staging.coorpacademy.com/h5p — the H5P service's path, copy-pasted into the external
      service's document. A client that selects the staging server sends external-upload requests to the
      H5P endpoint. The production server (.../external) is correct.

      Record the undeclared authentication and the presigned-URL semantics. The document declares NO
      securityScheme, but the api.coorpacademy.com edge is AWS API Gateway: an unauthenticated call to a
      sibling path on the same host returned HTTP 403 {"message":"Missing Authentication Token"} on
      2026-08-17. The operation is gated; the contract simply does not say how.

        Mints a presigned S3 URL for uploading external content of the given file extension. Returns the
        upload target; the caller then PUTs the bytes to S3 directly.

            Gated at the AWS API Gateway edge — sibling paths on api.coorpacademy.com return 403
            {"message":"Missing Authentication Token"} without credentials. The header name is not
            published for this service. Ask Coorpacademy.

          note: >-
            Each call mints a new upload target. Retries are cheap individually and unbounded in
            aggregate, with no rate-limit signal to throttle against.
        error_semantics: >-
          The 400 response is described as "Undefined/ Internal errors", so a 400 from this service is
          NOT reliably a client fault and must not be classified as permanently non-retryable.
