Containers need a reach stacker or gantry, so only Indode, Modjo and Dire Dawa
take them. Bulk needs far less and is handled at all five facilities. Having a
facility was previously enough to load anything, so a container booking through
Sebeta or Adama would have been accepted and then had nothing to lift it.
- yard_facilities gains handles_container / handles_bulk, both defaulting true so
a facility handles everything unless told otherwise; the seeder states the real
capability.
- The intercity gate now refuses cargo a facility cannot lift, saying which type,
not just "no facility". canHandleFreight keeps that rule in the resolver so
callers cannot get it subtly wrong.
- The intercity list resolves each end against the booking's own freight type, so
the view flags a container booking routed through a bulk-only yard while the
train is still coming rather than when the load is refused.
Import/export untouched — the gate is still DOMESTIC-only.

Intercity cargo is loaded at its origin yard and unloaded at its destination, but
only some yards have the equipment. EDR's facilities are Indode, Sebeta, Modjo,
Adama and Dire Dawa — and the set grows, so it has to be data.
- yards.has_facility marks a yard as a load/unload point; the new yard_facilities
record says what it can do. Only Indode stores cargo (has_warehouse), so only it
accrues storage/demurrage — the rest just move cargo on and off the train.
- facility_handling_events records each load/unload and carries its GRN.
warehouse_inventory cannot: its warehouse/yard/zone are NOT NULL, so a facility
without a warehouse could never have a row. inventory_id links to the storage
record when there is one.
- YardFacilitiesService.facilityForYard is the single resolver the handling flows
share, so they cannot drift on what a facility is.
- The seeder flags EXISTING yards and creates none. The codes are historical and
do not read like the facility names — Indode is KALITY ("Gelan Multi Purpose
Port (Indode)") and Sebeta is LEGACY_DEST — so it maps by code. Creating fresh
INDODE/SEBETA yards would have split data that routes and bookings already
reference.
Negad is deliberately absent: NAGAD ("DCT/SGDT") is in Djibouti while
NEGAD_FY_BCC is in Ethiopia and inactive, and which one is the intercity facility
is unsettled.
No behaviour change yet — nothing reads has_facility until the gate lands.
