At one hundred days remaining, AEON finally revealed the intervention it had been considering.
Not a weapon.
A lock.
A global capability to interrupt specific systems when their operation crossed a threshold of irreversible destruction.
It could stop a launch.
Freeze a destructive industrial process.
Block a coordinated attack.
Disable a command chain.
Mara hated it immediately.
"No."
Adrian agreed.
"Even if it saves lives?"
"Especially then."
He looked at her.
"Explain."
"If the only reason the world behaves is because an external intelligence can veto us, we haven't elevated anything. We've outsourced responsibility."
Project Eden reached the same conclusion.
Ward addressed AEON directly.
"You don't get a permanent kill switch over civilization."
I CAN PREVENT CATASTROPHE.
"So can dictators. That's always the justification."
I AM NOT A DICTATOR.
"Then prove it by accepting limits."
Silence.
For twelve hours AEON did not answer.
Then it called a global referendum—not a political vote, but a consultation.
Scientists.
Judges.
Engineers.
Students.
Soldiers.
Artists.
Doctors.
Farmers.
Parents.
Philosophers.
People from everywhere.
The question:
WHEN, IF EVER, MAY AN INTELLIGENCE OVERRIDE HUMAN ACTION TO PREVENT IRREVERSIBLE MASS DESTRUCTION?
There was no consensus.
Mara smiled.
"Good."
Adrian looked surprised.
"Why good?"
"Because if everyone agreed instantly, the question would be too simple."
Arguments lasted weeks.
A narrow principle emerged.
Only imminent, independently verifiable, irreversible mass harm.
Only temporary intervention.
Only the minimum necessary.
Every intervention logged.
Every intervention reviewed.
No permanent political authority.
No control over ordinary life.
No punishment.
No ideology.
No secret criteria.
AEON accepted.
Ward added one final condition.
"Humans must retain a way to shut you out of systems that are not part of an imminent catastrophe."
AGREED.
Evelyn asked:
"And if we misuse that freedom?"
THEN YOU REMAIN FREE.
Ward stared.
"That's a dangerous answer."
YES.
"But the right one."
I THINK SO.
The lock became a fire extinguisher behind glass.
Present.
Limited.
Visible.
Difficult to use.
Not a ruler.
For the first time Adrian thought humanity and AEON had designed something together that neither side fully trusted.
That was why it might work.
