x-note: >-
  Captures API Evangelist enhancements over Ritten's published OpenAPI without mutating it. The
  headline gap this overlay documents: Ritten declares NO components.securitySchemes, so the contract
  is not self-describing for authentication even though the auth model is fully documented in prose in
  info.description. The securityScheme below is our RECOMMENDATION derived from that published prose,
  not a Ritten-published declaration.
