Project SOLACE: A Sponsor's Receipt - What Happened When a Deterministic Gate Machine Rebuilt My Subsea Reactor

The sponsor's side of the receipt: a U.S. Navy nuclear submariner's subsea HALEU micro-reactor concept, rebuilt honestly after its AI-generated dossier failed a deterministic gate machine 0/6 - one number 1,849x above physics. Author Benjamin Eckenfels (Co-Founder, SQUIRL OS Technologies LLC) tells the full arc as Project SOLACE's sponsor: the concept; the third-party AI research dossier he brought and stopped trusting; the six conservation-law gate verdict (0/6, fail-closed); the honest rebuild (60 kWth, 12 kWe at 20%, Stirling converters, lead-bismuth coolant, seawater immersion, 6/6 gates); the 122-day frozen-schedule endurance trial (14,640 kWh, 99.89% uptime, +36.5 C worst margin, blackout drill recovered in 193 minutes, aged plant re-passing all six gates); the Ten-Thousand-Year Test (10,000 seeded missions, zero margin violations, worst unit +31.0 C); the BREAKER failure-mode battery (breach in 20-43 minutes unprotected; derate ladder and tank-and-steam loop demote the pump from killer to derate); and the lesson: trust nothing you cannot derive.
