Leveling display: a selection without a movement request
Original fictional electric leveling controller L-TRAIN. Supplied controller-mode and event records only.
Customer says: I selected the jack on the screen and nothing moved. Is the jack motor dead?
L-TRAIN includes a fictional display-only mode. Its mode contract is exercise data, not a feature claim about any real controller.
