x-note: 'Captures API Evangelist enhancements without mutating MyCarrier''s published
  contract. The largest gap this addresses: the contract declares an EMPTY
  components.securitySchemes and no top-level security[], even though every operation
  documents a 401 and the docs describe HTTP Basic auth. A generated client built from
  the raw contract has no way to authenticate.'
