  description: The published contract names only non-production hosts. Note the production gateway without asserting that this contract is deployed there - api.zinnia.io is the production host named by
    the other Zinnia contracts and required as the Auth0 audience, but Zinnia has not published this service against it.
  update:
    x-production-host-note: https://api.zinnia.io is the Zinnia production API gateway (declared by the Policy Service, Enterprise Documents, Case Management, New Business and New Business Annuity contracts
      and required as the Auth0 audience claim). This contract publishes non-production servers only; confirm the production path with Zinnia before use.
- target: $.info
  description: No contact is published in this contract. Record the one support address Zinnia does publish in a sibling contract rather than inventing one.
  update:
    x-support-note: 'Zinnia publishes orderentrysupport@zinnia.com as info.contact on the Market Connect Order Entry contract only. General contact: https://zinnia.com/contact'
- target: $.info
  description: Record the cross-cutting semantics derived for this provider so a consumer of the enhanced contract can find them.
