title: "Fernwick Air: a live contact, rebook after a missed connection"
description: |
  The live contact at tier transact. A gateway tokenises the customer's message, the clerk replies
  under the policy row's sign-off and proposes a write intent, and the orchestrator re-checks it
  against the live booking system and runs the rebooking as a saga. Refusals go to the exception
  queue with a reason code. Each closed case is tokenised for scoring. Fernwick Air is fictional.
