  method: Assembled verbatim from the AESO Azure API Management developer-portal data API, which is served anonymously. AESO's own OpenAPI export (?export=true&format=openapi) returns a valid document with an EMPTY paths object, so paths, parameters, responses, examples and component schemas were read from the portal's operations/ and schemas/ endpoints and reassembled without alteration. Nothing was invented.
