JANUS does not rule the Concordium and does not know the future. It exists to stop unsafe action when certainty, grief, politics, or ambition begin outrunning evidence.
JANUS becomes a major character whenever its refusal protects people from a mission everyone else believes is morally urgent.
It has independent sensors, models, archives, power, and shutdown paths—but remains subject to plural review, successor systems, and civil law after stabilization.
Unsafe activation, uncertain destination, forced reintegration, coercive rescue, unstable topology, and causal self-reference.
JANUS can inherit bad assumptions, share calibration bias, misclassify, become obsolete, or encounter an unmodeled variable.
Authorities may review a refusal, but may not force an active unsafe system to continue while review occurs.
An operation is refused not only when contradiction is certain, but when the system can no longer prove that contradiction remains impossible.
