  Entity graph derived from the identifiers and XML elements Breeze publishes in its
  NDC request/response samples and its selling-flow identifier documentation. Breeze
  publishes no OpenAPI or XSD, so this is a reading of the documented IATA Offers and
  Orders 21.3 message payloads as Breeze uses them — not a provider-published schema.

identifier_flow:
  note: >-
    Identifier values are re-minted between steps. See
    conventions/breeze-airways-conventions.yml (identifiers) — reusing an earlier
    step's OfferID can undo expected changes or error.
  sequence:
  - AirShopping returns many OfferIDs
  - OfferPrice consumes one or many OfferIDs and returns a single priced OfferID
  - ServiceList and SeatAvailability consume the priced OfferID and return their own response IDs
  - OrderCreate consumes the priced OfferID and its OfferItemIDs and returns an Order
  - OrderRetrieve, OrderReshop and OrderChange operate on OrderRefID and OrderItemRefID
