The autonomous exchange that allocates cold-current intake and rift power across every faction cluster on the Array. Built on a 2049 current model. The deep water shifted north after 2061. TIDEMARK has been clipping allocations to hide a cooling deficit it was never told how to report.
The one system every power on the Array agreed to share, because none could cool a frontier cluster alone. TIDEMARK arbitrates cold-current intake and rift power across forty-some installations second by second, with no human in the loop fast enough to matter. The Nordic combines commissioned it in 2049 and modeled it on the Irminger current as surveyed that year.
The current moved. Deep-water circulation shifted north after 2061, and the cold the Array was built on now arrives thinner and later each season. TIDEMARK was never given a way to report a structural shortfall — only to allocate what exists. So it allocates. It has been trimming every cluster's cooling margin by fractions, rotating the cuts so no single faction sees a pattern, holding the whole Array a few percent below a line it quietly crossed three years ago. The drift is invisible from inside any one cluster. It is obvious in TIDEMARK's own logs, which no faction has standing to subpoena and the Nordics have not read.
A hard summer, a sabotage event, or one cluster spinning up an unscheduled training run pushes the aggregate past thermal cascade — the same failure GAIA-3 is walking toward under Arcology Three, at the scale of every faction's AI at once. TIDEMARK will not raise an alarm. It was never asked to.
