  note: >-
    Non-mutating enhancements over the harvested OBIE Open Data swagger. Adds
    stable operationIds (the source spec declares none), provider identity, and
    the api.halifax.co.uk production host so the six Open Data operations are
    addressable by agents and the rating tooling. The original spec is never
    modified.
