add Group 9 delivery scenarios for self-haul and last-mile paths
- Implemented G9·S38 tests for customer self-haul truck assignments, ensuring compliance with container limits and truck assignments. - Added G9·S39 tests for last-mile delivery, self-haul, and yard pickup, verifying independent paths for multiple bookings on the same train. - Created seed data for Group 1 and Group 2 scenarios, ensuring proper setup for weight and capacity tests. - Updated booking interface to deprecate in favor of for better clarity in allocations.

-- Arrange-data for the GROUP 2 weight/tolerance scenarios (flows/g2_weight.cy.ts).
|
||||
-- Run AFTER seed-import-corridor.sql. Idempotent.
|
||||
--
|
||||
-- Group 2 is the only group where WEIGHT binds before slots. Group 1's train
|
||||
-- (TRN-G1-1) deliberately keeps every non-slot axis slack; this one does the
|
||||
-- opposite, so the two must never share rolling stock.
|
||||
--
|
||||
-- THE ARITHMETIC (all from train-capacity.util.ts)
|
||||
--
|
||||
-- The weight axis is GROSS — a locomotive hauls the wagon as well as its
|
||||
-- cargo (`grossWagonWeightTons` = tare + cargo). NW5 tare is 22.4T, and two
|
||||
-- 20ft containers ride one NW5. So with a heavy VGM of 28T per container:
|
||||
--
|
||||
-- wagon gross = 2 × 28 + 22.4 = 78.4T ← S9's number exactly
|
||||
--
|
||||
-- S9 base pull 3500T: 35 wagons × 78.4 = 2744.0T ✔ fits
|
||||
-- 45 wagons × 78.4 = 3528.0T ✘ over base
|
||||
-- → C is blocked on WEIGHT while 18 slots still sit empty.
|
||||
--
|
||||
-- S10 tolerance 90T → cap 3590T: 3528 ≤ 3590, so C is admitted WHOLE.
|
||||
-- Tolerance is spendable ONLY to admit a booking whole.
|
||||
--
|
||||
-- S11 after 2744T used, base room = 3500 − 2744 = 756T.
|
||||
-- 756 / 78.4 = 9.64 → a split may size at most 9 wagons (705.6T).
|
||||
-- It may NEVER reach 10 by dipping into the 90T tolerance, because
|
||||
-- sizePartialOfferWagons budgets against BASE only
|
||||
-- (train-capacity.util.ts:58, booking-batch.service.ts:4109).
|
||||
--
|
||||
-- S12 light cargo (12T/container): wagon gross = 2 × 12 + 22.4 = 46.4T.
|
||||
-- 53 × 46.4 = 2459.2T — only 70% of base. SLOTS bind, not weight.
|
||||
--
|
||||
-- TWO LOCOMOTIVE PAIRS, ONE TRAIN EACH
|
||||
--
|
||||
-- Pull weight ADDS UP across a set but length takes the MINIMUM
|
||||
-- (combinedLocomotiveLimits, train-capacity.util.ts:358), so a pair of 1750T
|
||||
-- locos gives exactly the 3500T base the scenarios assume. Weight tolerance
|
||||
-- adds up too — hence 45T each for the 90T set.
|
||||
--
|
||||
-- TRN-G2-BASE LOCO-G2-A/B 1750T each, tolerance 0 → 3500T base, no slack
|
||||
-- TRN-G2-TOL LOCO-G2-C/D 1750T each, tolerance 45T → 3500T base + 90T
|
||||
--
|
||||
-- Both carry 53 NW5 wagons so the SLOT axis is identical to Group 1 and any
|
||||
-- difference in outcome is attributable to weight alone.
|

|
||||
-- 1. Locomotives. Length 760m keeps the length axis slack (53 × 13.966 =
