A 99 per cent confident AI is still one per cent away from catastrophe. The AI systems governing the world's most critical infrastructure — airspace, satellites, orbital corridors, space observatories — make high-frequency celestial decisions per second. No cryptographic proof exists that any single one was made within the boundaries authorised. The difference between a recoverable error and an existential event is one ungoverned decision at the wrong altitude, in the wrong corridor, at the wrong moment.The 0→1 Doctrine delivers verifiable proof at decision—closing the black box gap.
