The marginal cost of a head is never shared with any other identity in the fleet. The mesa is the attested output, the nebula the stranger who checks it, and the harbor the tier the pair unlocks; the mesa is per identity, the nebula cannot be the farm's own, and the harbor is what waiting alone cannot buy.",
