  note: 'Verbatim copy is openapi/_original/elsdoc/elsevier-engineering-village-swagger.json. This copy differs from the source in exactly two mechanical ways: Elsevier''s external path $refs (./listings/<Name>#/<op>) were inlined from the provider''s own listing documents (also saved verbatim under openapi/_original/elsdoc/listings/), and info.title was filled in where the provider left it empty. No operation, parameter, response or schema content was authored by API Evangelist.'
