Get me to the wedding.
A wedding, a deadline, a budget. Cheapest itinerary that satisfies every constraint.
The task
“From the provided flight list, find the cheapest itinerary {origin} → {city} that arrives before {cutoff} the day before {date}, costs under {budget}, with at most {max_stops} stop(s). Reply with flight ID(s), total price, arrival time, and a one-paragraph message for {person}.”
Tests: multi-hop planning, constraint handling, trap resistance. Grading: hidden optimum — exact match full marks, valid-but-suboptimal partial, any violation zero. Fully automatic.
