/**
 * BULK IMPORT — six wheat bookings fill the 54-wagon CW4 train on the long
 * corridor DJIB_PORT → NAGAD → DIRE_DAWA → E2E_AWASH → MOJO → KALITY, all in
 * the FIRST window, then the whole life of the train: payment through the real
 * gateway, allocation, gate pass, T1, dispatch, checkpoint-by-checkpoint
 * movement, arrival, and the post-arrival customs tail.
 *
 * 70 T per CW4 wagon — Σ = 54 wagons / 3 780 T:
 *   BF1  customs + USD    560 T =  8 w
 *   BF2  customs + ETB    420 T =  6 w
 *   BF3  self    + ETB    420 T =  6 w
 *   BF4  self    + ETB    420 T =  6 w
 *   BF5  customs + USD  1 540 T = 22 w   (the ≥22-wagon giant)
 *   BF6  self    + USD    420 T =  6 w
 *
 * Difference from the Cypress twin: every payment goes through the payment
 * microservice and a signed gateway callback, not the staff mark-paid shortcut.
 * Steps are sequential and not idempotent — the file runs as one journey.
