+-- FLOW-TWO fixture — the EXPORT-direction, THREE-POOL consist.
+--
+-- Run AFTER seed-import-corridor.sql. Idempotent.
+--
+-- WHY THIS TRAIN EXISTS
+--
+-- The second flow-two batch is written against a "60 wagons = 35 CNT + 20 BLK
+-- + 5 FLT" baseline, running F→A (KALITY → DJIB_PORT). Nothing in the existing
+-- fixtures gives that:
+--   - TRN-G1-1     is 53 × NW5, one pool, parked at DJIB_PORT (import end).
+--   - TRN-F2-MIX   is 30 NW5 + 20 PW2 — two pools, also at DJIB_PORT.
+--   - TRN-LEDGER-PW2 is 37 PW2 at KALITY — right end, wrong pools.
+--
+-- TRN-F2-EXP is 60 wagons at KALITY split across THREE cargo-incompatible
+-- types, so "container overflow must not eat bulk wagons" (TC-02) and
+-- "bulk-to-container substitution" (TC-03) are expressible at all. On a
+-- one-pool consist the abstract slot count and the physical stock count are
+-- the same number, and a broken pool separation is invisible.
+--
+--     35 × NW5 — CNT. The only type 20FT/40FT containers ride
+--                (container_type_wagon_types, seed-import-corridor 2b).
+--     20 × CW4 — BLK. Carries E2E_IMP_WHEAT (cargo_type_wagon_types, 5b2).
+--      5 × NW6 — FLT. Allow-listed to NOTHING here, deliberately: it is the
+--                idle-but-unusable pool TC-02 asserts a container booking may
+--                NOT reach for. See section 5.
+--
+-- LENGTH AND PULL MUST NOT BIND — this suite tests SLOTS and TYPE, and a
+-- length rejection would masquerade as a pool rejection:
+--     35 × 14.000 + 20 × 13.976 + 5 × 18.560 = 490.0 + 279.5 + 92.8 = 862.3 m
+-- so the locos below run 1000 m. Gross weight at full load is roughly
+-- 60 × (70 + ~25) ≈ 5700 T, so the pull is set to 12000 T. Both axes stay
+-- slack; only wagon slots and wagon TYPE can ever bind.
+--
+-- The wagon numbers (WGN-F2X-*) are distinct from every other fixture's, so
+-- this consist never competes for stock with the import specs.
+
+-- 1. Locomotive pair at KALITY (the export origin), 1000 m so length is slack.
