    Captures API Evangelist's enhancements to the harvested contract without mutating it.
    The original is preserved verbatim at openapi/_original/. Every action below adds
    metadata the published spec omits — a servers block, contact/licence/description in
    info, and machine-readable notes on the operations whose behaviour a consumer cannot
    otherwise infer. Nothing here invents API behaviour.

      SponsorUnited publishes no developer portal, API reference, getting-started guide or
      sign-up path for this API; the contract is the only public documentation of it.
