// CRITICAL INVARIANT: Every itinerary option returned to users MUST have
// valid travel segments between ALL consecutive stops.
//
// N stops → exactly N-1 travel segments. No exceptions.
//
// This file tests the invariant at every layer:
// 1. ItineraryBuilder.build() — the segment factory
// 2. ItineraryOption.isValid — the runtime check
// 3. TripPlanningEngine — the final gate
// 4. Each scenario planner (A-E) — end-to-end
// 5. Edge cases — single stops, same-city, missing coords, cross-country
