Phase 1 seed dataset — under review. These rows were compiled by hand from public operator, laboratory and vendor sources, and have not yet been through a second-reader verification pass. Every claim carries its source and a confidence tier; treat anything below verified as a lead, not a citation.

What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

The read
The European counterweight to LUMI, and a different supply chain: Eviden integration on the BullSequana XH2000 platform, Intel hosts, NVIDIA A100 accelerators in a custom 64 GB variant, NVIDIA HDR InfiniBand. Eviden is the corporate descendant of Bull, so this row is one of the places where the vendor-alias table earns its keep — an unresolved dataset would scatter the same supplier across Bull, Atos and Eviden.
