edr-platform/e2e/freight/cypress/fixtures/seed-segment-weight.sql

-- Arrange-data for flows/segment_weight.cy.ts. Idempotent.
-- Run AFTER seed-intercity.sql + seed-export.sql (container types, E2E_WHEAT
-- cargo, Mojo→Djibouti rates, yard distances come from those).
--
-- Two dedicated trains on the Mojo → Dire Dawa → Djibouti Port corridor:
--
--   TRN-SEG-W ("tolerance train")  — locos 240T pull; LOCO-SEG-A carries a 90T
--     overage tolerance, LOCO-SEG-B has NONE CONFIGURED (null). The S-2026-00024
--     regression pair: min-across-locos must keep the 90, not zero it.
--     Consist: 2 CW4 (bulk) + 2 NW5 (containers).
--
--   TRN-SEG-F ("border-full train") — locos 200T pull, no tolerance.
--     Consist: 4 NW5. An 8×20ft export boarding at Dire Dawa commits every
--     wagon on the border edge → the train goes FULL for its trade direction
--     while the Mojo→Dire leg stays free: an intercity ride-along boards the
--     SAME wagons there and alights before the export loads them.
--
-- Wagons are dedicated inserts (WGN-SEG-*) so the fixture never competes with
-- other specs for free fleet stock, and the corridor targets NAGAD (not
-- DJIB_PORT) so no other spec's same-day schedule can steal FCFS bookings.

-- 0. Reset any PREVIOUS segment-weight run (namespaced: TRN-SEG-* trains,
-- CTR-SEG-* contracts, WGN-SEG-* wagons) so the spec re-runs on a warm DB.
-- Everything is age-guarded (45 min): Cypress re-runs the spec's before()
-- hook on cross-origin reloads, and an unguarded reset would soft-delete the
-- CURRENT run's own schedules and contracts mid-flight. Consequence: rerun
-- the spec no sooner than 45 minutes after a crashed run (or restack).
