title: "Fernwick Air: rebook after a missed connection, tier shadow"
description: |
  Tier shadow. The rep handles the case exactly as at tier off. Side by side, a gateway swaps the
  customer's personal data for tokens, and a model, the clerk, answers the same case. Its answer goes
  only to a judge model, which scores it against what the rep did. Nothing the clerk writes reaches
  the customer or the booking system. Fernwick Air is fictional.
