**What it does not test.** This does not establish volume production of Rhea1 or that JUPITER's node count runs mainly on European rather than AMD silicon.

**How this item counts.** Towards autonomy: it changes who made the parts. Binding 3 of 3 (in force or operating), scale 1 of 3 (small), Verified counts in full: weight +3 of 36 possible. European Rhea1 chip samples delivered for JUPITER; parts moves, but only samples not volume. [European Sovereignty Index](https://sovereigntymonitor.eu/sovereignty-index/)
