A policy changes, and so does the answer.

A fictional airline, Senua Air, has a travel policy: flights under five hours are booked in economy. Later the same day an amendment says flights from Gatwick are upgraded to business. The engine reads the first memo, answers from it, reads the second, and changes its answer.

Before the amendment

A three-hour flight: economy, citing the policy line.

After the amendment

A two-hour flight from Gatwick: business, citing the amendment. A two-hour flight from anywhere else: still economy.

How it was checked

The end-to-end run repeated five times out of five, twice. Learning a memo took about four seconds. This is a demonstration, not a benchmark.
