Field notes
The service, agent, and voucher are simulated together in the browser rather than communicating across a network. The page says the caveat contains a fresh key and a question sealed for the voucher, and identifies a secret root key plus an honest voucher answer as load-bearing assumptions. Payment, caveat expiry, and key distribution are outside the demonstrated implementation.
