Auradine Teraflux AI3680 (Immersion)

U.S.-designed immersion Teraflux (AI = Auradine Immersion), and it is TUNABLE 0-375 TH/s. MARA runs these de-tuned to ~210 TH/s (~16 J/TH) for efficiency rather than the ~360-375 TH/s ceiling - so the fleet 'sticker' 210 is a chosen operating point, not the rated max. Proprietary SMART hashboards; three-phase, dielectric fluid. (Published max efficiency varies by source: ~15 J/TH optimal vs ~19 J/TH at 360 TH/s.)
