Liftcraft Dispatch lab

Transport the required number of people before the time, waiting-time or move limit. A passenger counts only when they reach their destination. Routes repeat; hall calls join the nearest lift’s queue using distance, queue length and load. Passenger buttons add destination stops. A high queue penalty spreads work across lifts.

For the first assignment, visit all three floors. Later, try dividing floors between lifts, balancing hall calls and passenger destinations, or prioritizing destinations. Edit your plan while paused, then Apply plan & restart. Run also resumes a paused simulation; Restart starts a fresh random traffic pattern. Space toggles Run/Pause outside form controls.

This is a declarative route-programming edition of Elevator Saga. It preserves the original physics, passengers and first eight challenges. Routes and medals persist locally; an in-progress simulation restarts when you reload.
