    description: >-
      Replace Adobe's placeholder host. The published spec carries
      `host: localhost:8080`, which is non-routable. Marketo's real base is
      per-subscription and templated on the Munchkin ID, documented at
      https://experienceleague.adobe.com/en/docs/marketo-developer/marketo/rest/base-url
    update:
      x-apievangelist-base-url: 'https://{munchkinId}.mktorest.com'

      Record the security scheme the provider documents but does not declare.
      No published Marketo spec contains securityDefinitions or
      components.securitySchemes.
    update:
      x-apievangelist-authentication:
        type: oauth2
        flow: clientCredentials
        tokenUrl: 'https://{munchkinId}.mktorest.com/identity/oauth/token'
        transport: 'Authorization: Bearer'

    description: >-
      Flag the response-semantics hazard the spec cannot express. Marketo returns
      HTTP 200 for authentication failure, rate-limit exhaustion, quota
      exhaustion and per-record write failure; the real signal is the body's
      `success` member.
    update:
