Corridor transport lowered one major cost in off-world movement, but it did not flatten the cost curve. It moved concentration into the handoff minutes that follow exit.
Those minutes remain expensive because they are asked to do too much at once. A craft has to reacquire its conventional operating model, confirm geometry, stabilize custody, and commit to the next leg without squandering the advantage that corridor insertion created in the first place. Every system that matters suddenly becomes timing-sensitive together.
That is why operators obsess over handoff windows more than outsiders expect. Savings earned during the transit envelope can disappear quickly if reacquisition burns are late, overcompensated, or forced into crowded downstream traffic.
The broader lesson is that corridor economics are not mostly about cheap movement. They are about where movement remains stubbornly expensive even after the route itself becomes more favorable.
