Shared-Ride Pooling Engine

What the engine checks, in order

1. 1Anchor time — flight arrival or requested departure, inside the window
2. 2Direction — corridor must match, so the van never doubles back
3. 3Vehicle fit — seats, luggage bays, child seats and wheelchair access
4. 4Detour cost — extra minutes the added pickup puts on the run
5. 5Stop order — furthest pickup first, so the van fills toward the airport
6. 6Minimum viable load — a run under the floor is held, not dispatched

Private-vehicle jobs are never pooled. They appear on dispatch as single-van runs.
