What this vertical is — and is not
Gatehouse PC, yard RF, shipping-office EUC. Not stevedoring, not shipboard, not a VGM/scale SKU.
SLA pattern: Priority on gatehouse / TOS-adjacent PC that stops the gate. NBD on office. Vessel-window IMAC is often OOH.
Compliance: Port ID is the terminal's. ISPS induction time >30 min is T&M. Lithium handhelds are UN38.3, not a Zion spare.
