End-to-end testing of the direct truck-to-train flow surfaced two defects
in the carriage acceptance sheet's no-wagon fallback. Container numbers
were read from freight.containers, which only gains rows at allocation,
so a direct booking's declared containers never appeared; they are read
from booking_container_units now, seal numbers included. The weight used
bulkTotalWeightTons alone, which is null for CONTAINER and PER_TON bulk
bookings, printing 0.00 — cargoTotalWeightVgm is the real weight there
and only holds an item count for PER_ITEM break-bulk.
Separately, warehouse cargo can be loaded from the Load-to-Train queue or
from the schedule, but loading from the schedule never advanced
warehouse_inventory. The booking went IN_TRANSIT while its cargo still
read as sitting in the warehouse — the same inconsistency that produced
the spurious dispatch block. loadBooking now moves the inventory to
LOADED in the same transaction, and no-ops for direct bookings.
Export cargo reaches a train two ways, but the platform only modelled
one. Direct truck-to-train cargo loads straight onto the wagon, never
enters a warehouse and so never has a GRN — yet assertExportReceivedWithGrn
required one before the carriage acceptance sheet could be issued or the
booking loaded from inside its schedule.
Adds export_handover_mode to freight.bookings (null = WAREHOUSE, so
existing bookings are unaffected) and teaches the shared gate to skip
DIRECT_TO_TRAIN. Both call sites are fixed by that single early return.
For direct bookings the carriage acceptance sheet builds its lines from
the booking's own containers, falling back to the declared bulk tonnage,
and is issuable as soon as the mode is chosen. Direct bookings are also
removed from the warehouse receive queue, since that cargo is never
coming to the shed.
Staff choose the mode from the booking detail page via a new endpoint
reusing bookings:operations. Switching to direct is refused once
warehouse inventory exists, so the two flows cannot cross.
Warehouse-then-train keeps every gate it had.
