- Introduced new yard distances resource with CRUD operations.
- Created migration for yard distances table with necessary constraints.
- Implemented service and repository for yard distances handling.
- Added controller for API endpoints to manage yard distances.
- Updated rule engine configuration to include yard distances.
- Enhanced rule engine resource page to support yard distance selection.
- Updated contracts and train builder pages to handle new yard distance logic.
- Added error handling utility for better error message extraction.
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.
