Watermark · directory · the three hypotheses

One network, three hypotheses

The platform-level index now holds 35 sites · 10 basins. The watershed lens — where compute meets water and power — is the live reference build (Lima / BOSC). Two further theses are opening alongside it: defense & federal-enclave analysis, and corporate & economic surveillance. The directory reads the same network through whichever lens you pick.

Not mutually exclusive — a single site can sit in all three. Lima (BOSC) is the worked example under each.

H1 · Water & Coercion Reference build
Where discharge becomes leverage.

The original thesis: hyperscale compute lands where it can pull power and water, and a data center's intake, discharge, and downstream effects are basin facts. Sites nest by drainage — two divides, nine basins. Lima is the live, fully-assembled reference. A coercion sub-thesis (#903): in municipalities with declining populations, the receiving WWTP may be running lean on influent — below the biological-treatment minimum that keeps it in NPDES compliance. A datacenter's high-volume, consistent discharge provides the flow buffer the plant needs, structurally compelling municipal acceptance. The Clean Water Act is the backstop that makes the need non-negotiable.

A dash means the section isn't assembled yet — never a zero, which would read as a finding.
H2 · Defense & Federal Enclave Emerging hypothesis
Where the build-out meets federal land and the defense base.

A second reading: the same map tracks arsenals, air bases, federal research and the CHIPS build — enclaves where federal jurisdiction, clearance, and defense supply chains concentrate. Newly opened; most sites are not yet assessed, and a federal nexus is a signal, not a verdict.

H3 · Consumer Surveillance Emerging hypothesis
What the compute is for, who it watches, and who's paying.

A third reading: the operators behind shell LLCs, the public-subsidy stack that pulls them in, and the capital and data flows the facilities sit on. The consumer-surveillance thesis — opening now, mostly under investigation, with Lima's abatement on record. An end-use sub-thesis (#904): these facilities are infrastructure nodes in a consumer surveillance apparatus — behavioral tracking, financial-transaction processing, or similar mass-scale surveillance of individual consumer activity, financed in part by the public subsidies the same communities provide.
