The story
Phileas Fogg arrives in Paris at 11:40 pm.
- Fogg is going around the world on a wager, and cannot lose a night. His valet's AI agent, Passepartout, books an unsold twin room at Montparnasse Central for $194.99, signing the booking's terms with the payment.
- At the desk: "Monsieur, that rate is not in our system. Tonight it is $512."
- Passepartout shows the booking. Its Agentic Transaction Record names the hotel, the room, the dates, the price and the terms by their fingerprint; the payment signed it.
- The terms' section 3 is quoted back: the booked price stands. The desk checks the record in seconds.
No argument, no midnight phone call. Fogg sleeps, and keeps his schedule. Try the front desk
