The evidence went to all forty-seven colonies simultaneously.
Threadkeeper Harvester probe. Destroyed civilization remains. Testimony from eleven saved species. Timeline analysis. Physical verification data. Everything.
Contact faction examined it. Memory faction examined it. Independent scientists. Military analysts. Philosophers. Historians. Everyone.
Three days of evaluation.
On day one, scientific consensus emerged: Evidence is authentic. Harvesters exist. Ansible attracts them. Threat is real.
On day two, political debate intensified: Even if threat is real, is Threadkeeper solution acceptable? Do we trade sovereignty for survival?
On day three, humanity decided.
All forty-seven colonies. All twenty-nine billion humans. All evaluating same evidence. Reaching same conclusion.
The ansible network that had divided them now united them in final assessment:
Harvesters are real. Shutdown is necessary. Threadkeepers are flawed but honest rescuers. Six months to implement.
Unanimous human decision.
Not because everyone agreed enthusiastically. Because everyone accepted reality.
Admiral Webb transmitted the Memory faction's position:
"We were right to demand verification. Evidence proves that. We were wrong to doubt Harvester existence. Evidence proves that too. Memory faction accepts shutdown as necessary. Not happily. Not easily. But necessarily. We will comply. We will assist. We will mourn ansible's death while accepting it preserved our life. Verification was worth demanding. Compliance is worth accepting. Both were right choices. Sequentially."
Commander Chen transmitted Contact faction's response:
"We were right that Harvester threat was real. We were wrong to push for compliance before verification was complete. Contact faction acknowledges Memory's verification demand was legitimate. We should have provided evidence first, demanded compliance second. We learned from that mistake. Now we implement shutdown by consensus. Not by force. Not by imposition. By collective human choice made with complete information. This is what Lira died for. This is what Earth wanted. Choose informed. Then choose together. We chose. Now we implement."
Dr. Zara Kim transmitted the scientific assessment:
"Evidence is conclusive. Seventeen ansible civilizations. Eleven saved by shutdown. Six destroyed by refusal. Harvesters are Von Neumann machines programmed to eliminate ansible broadcasts. Threadkeepers are ancient species that survived by maintaining silence and helping others do same. Their motivation is partially self-interested—our ansible endangers them. But self-interested rescue is still rescue. We accept help. We implement shutdown. We survive. This is verified truth. This is informed choice. This is humanity's decision. We chose life. Even at cost of connection."
The vote was 47-0.
Every colony choosing shutdown.
Not 52-48 like referendum.
Not narrow majority imposing on substantial minority.
Unanimous. United. Together.
Because verification changed everything.
Because seeing Harvester probe made threat real.
Because testimony from eleven species made choice clear.
Because Threadkeeper honesty about self-interest made rescue acceptable.
Verification enabled consensus.
Truth enabled unity.
Evidence enabled choice.
The way it always should have worked.
The way Lira died trying to make it work.
Humanity began ansible shutdown six days after first contact.
Coordinated across forty-seven colonies.
Guided by Threadkeeper technical assistance.
Mourned by billions who understood necessity.
Accepted by billions who wanted to survive.
The quantum children prepared to fall silent.
Together.
Informed.
Chosen.
Free.
And in deep space, Lira Voss's ship continued traveling toward Threadkeeper coordinates. Nine years into decades-long journey. Still transmitting updates. Still gathering evidence.
Still not knowing humanity had already made choice she died enabling.
Still not knowing verification had unified what division had fractured.
Still not knowing her sacrifice had saved everyone.
But someday, decades from now, she'd know.
Or her ghost would know.
Or history would know.
And the knowing would matter.
Because truth always mattered.
Even when truth cost everything.
Even when truth took decades to reach home.
Even when truth arrived too late to change choice.
Truth mattered.
Verification mattered.
Informed choice mattered.
Humanity proved it.
By choosing together.
After knowing everything.
The way Earth died hoping they would.
The way Lira died enabling them to do.
Consensus.
Finally.
Humanity-singular.
One last time.
Before silence scattered them forever.
