An autonomous exchange built to divide cooling and power between NAF's rig and the EO's converted gas platform two years behind it. The Array has a referee before it has a name.
TIDEMARK has exactly one job: divide the cooling fairly and let no faction's thumb sit on the scale. It was commissioned in 2049, when the Array was one NAF rig and one EO platform, four years before the mineral crunch made everyone a leaseholder.
