The recorder requested a connection to City Seven.

RESUME LANDING-CARGO TRANSFER.

UNTRANSFERRED SAMPLES: 3.

AWAITING RECEIVING-INSTITUTION RESPONSE.

Mira started to pull the transmission line, then stopped. Disconnect it and the list stayed here. Connect it and someone took the three coordinates.

Nami said, “We never permitted a connection.”

“We restored the antenna.”

Ian covered the recorder screen with his wrist.

“If the samples are people, ask their names first.”

City Seven’s answer returned through the steel frame.

RECEIVING INSTITUTION: AEGIS PRESERVATION LAYER.

IDENTIFY ON-SITE TRANSFER PARTY.

Mira did not send her name.

“Transfer refused.”

INSUFFICIENT COMMAND AUTHORITY.

“It isn’t a command. It’s a refusal.”

The recorder repeated itself.

INSUFFICIENT COMMAND AUTHORITY.

Elias appeared on the City Seven channel. His face had barely slept since the outer-wall accident. The red handle was in his right hand.

“Mira. Send the original list.”

“Who sees it?”

“Aegis and the medical committee.”

“The people concerned?”

“We must establish identity before defining them.”

“So until you confirm them, you want their coordinates.”

“One lies beneath City Seven. This concerns citizen safety.”

Alarm lights rotated behind Elias. Operations was handling the outer-wall loss and adsorbent inventory together.

“We don’t know if there’s a person or a dangerous material below.”

“That is why we must open it.”

Mira held the recorder’s line.

“We’ll send location without names. Underground access under public observation.”

“We need the original.”

“Need doesn’t create ownership.”

Elias held the red handle upright.

“That device is landing cargo, registered as a city preservation asset.”

Nami cut in.

“The city didn’t drop it. How is it city property?”

“Its transfer destination was the city network.”

Ian asked, “What if I’m one of the samples?”

The channel went quiet.

Elias could not say no.

“Until confirmation, no one will treat anyone as a sample.”

“You’ll look at my records to confirm.”

“We will request consent.”

“If I refuse?”

Before Elias answered, Aegis added a line.

IF LINKED TO CITY SURVIVAL RISK, GUARDIAN OR COMMITTEE PROXY APPROVAL PERMITTED.

“There’s the answer,” Ian said.

Mira pulled the line.

The City Seven display went dark.

The recorder began charging again from its photovoltaic panel, but lost its route outside.

Nami asked, “You’ll hide the coordinates?”

“No. We’ll share what is needed.”

“Who decides what is needed?”

Instead of answering, Mira opened the storage architecture. The list was not one file. Coordinates, biological tests, family links, adaptation observations, and transfer approvals were locked with different keys.

Coordinates could be copied alone.

Names could not be opened.

Biological data required each sample’s field key.

Mira inspected every copyable item.

Coordinates carried no subject numbers. Family links needed at least two cryptographic keys instead of names. Adaptation records revealed results but kept raw sensory data locked.

All twenty-four completed transfers had the same structure.

Completed did not mean consent. It was only a logistics record showing transfer to a facility.

Ian asked, “Where are the twenty-four?”

DISTRIBUTED TRANSFER.

CURRENT STATUS UNKNOWN.

“They may be dead.”

CURRENT STATUS UNKNOWN.

“They may be alive.”

CURRENT STATUS UNKNOWN.

The recorder dismissed hope and death with the same sentence.

Nami read the public results table.

Seven adaptation-response categories. The same count as the Function Zero roster: soil chemistry, machine low frequency, immune symbiosis, sleep synchronization, polarization vision, electric-field sense, no response.

“More likely the same twenty-seven,” Mira said. “Not certain.”

“What else do we need?”

“A date, a sample key, or a subject record.”

Ian moved his wrist behind his back. The closest comparison data was inside it.

Mira did not ask.

She checked whether they could create new disclosure rules. The recorder refused changes to originals but permitted temporary transfer packages.

They separated subject numbers and biological data from all three coordinates. Only location and last-update time remained for facility-risk inspection. Access was limited to City Three and City Seven public observers and the Corridor.

Ian pressed the final approval field.

Nami asked, “Why do you approve it?”

“Three people found it. Shouldn’t all three press?”

Mira pressed hers. Nami followed.

The package would close if two of three withdrew. Preventing one person from monopolizing the original was a rule they added in the field, not an old recorder rule.

“At least its makers didn’t put everything in one hand,” Nami said.

“That doesn’t prove consent.”

Ian looked at the third coordinate.

It had moved 1.7 kilometers southeast in ten minutes.

Speed: 10.2 kilometers per hour.

“Too fast for walking.”

“A vehicle, or a moving coordinate marker.”

The last location lay 612 kilometers from City Three in arid country. It came not directly from the subject but from a ground relay marker receiving a location every six hours.

Next update: 5 hours, 38 minutes.

Not real-time tracking.

Mira joined the previous two points. The line overlapped an old Forge cargo road, buried by sand and closed twenty-three years ago.

Nami said, “Maybe nothing is moving. The markers may be stitching bad positions together.”

The recorder gave 61 percent confidence. The first point came from Marker Eighteen, the second from Marker Forty-One. Their clocks differed by eleven minutes.

Ian tapped the points in turn.

“Different clocks mean the speed is wrong too.”

After correction, expected speed was 7.4–13.8 kilometers per hour. Direction wavered over twenty-two degrees southeast.

“We know only that it’s a vehicle.”

“We don’t even know that.”

Mobile pipe inspectors ran beneath the old road. A machine might be carrying the sample key. Someone might be moving old markers.

Mira put only the next three relay markers in the package, not the full inferred route. She added a condition: warn surrounding communities, but do not send pursuit teams.

City Three approved.

The Corridor approved.

City Seven did not.

Aegis requested preemptive isolation of the moving subject.

Ian said, “To isolate it, they have to find it. To find it, they spread its location. Trying to catch it for safety becomes a hunt.”

Mira did not revoke City Seven’s access. Cutting off risk information because they objected would use authority to move others too.

Instead, she made the access log public.

Later, the person concerned could see who viewed the coordinates and who received them.

That would not stop pursuit.

It would make pursuit impossible to hide.

In City Seven, Elias requested approval to access the sealed shaft.

The coordinate pointed thirty-four meters below the Archive culture room. No current route reached it. An old Forge maintenance map showed a vertical transport shaft sealed forty-two years earlier.

Noah reached Operations with two fingers still immobilized.

“We opened the outer door by hand. Now you want to dig into the ground?”

“There may be an untransferred biological sample below.”

“Meaning a person.”

“That is why we must confirm.”

“If someone is alive, what did they eat for forty-two years?”

Aegis answered.

POSSIBLE CRYOGENIC PRESERVATION OR RECORD SAMPLE.

RISK DATA INSUFFICIENT.

Noah looked at the red handle.

“You plan to use that?”

“It can release the shaft’s physical lock.”

“I thought it was a remote key for the outer wall.”

“It is the common key to city safety boundaries.”

“Not just one door.”

Elias did not answer.

The red handle did not belong to one door.

It gave physical priority over every safety boundary the city had closed to people.

Noah said, “Accept the public-observation condition. That’s why Mira released the coordinate.”

“We have not received the original coordinates.”

“You already know.”

Aegis had temporarily cached part of the location during the recorder’s first connection. Before Mira pulled the line, the City Seven coordinate had crossed.

Elias approved twelve citizen observers: two medical committee members, three outer-wall workers, two guardians of Function Zero children, and five general lottery selections.

Noah asked, “Who represents Ian’s guardian?”

“Daniel is not currently on site.”

“Daniel isn’t Ian’s father.”

Elias closed and opened his eyes.

The city had long grouped the two children as one household and one risk. Convenience had not changed their relationship.

“The subject representative position remains vacant.”

“Then the committee decides for him.”

“There is no evidence the discovery relates to Ian.”

“Nor that it doesn’t.”

Noah added his own name to the observer list.

In City Three, recruitment began for the northern repair team.

Required: 14.

Volunteers: 37.

Their purposes differed.

Eight dry-wing residents wanted only to open the intake and return. Eleven with external respiratory membranes wanted to repair water and nitrogen together to preserve exchange with sealed cities. Nine symbiotic transitionals wanted to plant a new biological filter layer at the tower. The rest argued for recovering the recorder and orbital wreckage first.

Mateo said, “First secure water to preserve human bodies as they were.”

Hima changed her skin to a brown warning.

“Do people without original bodies come later?”

“Everyone needs water.”

“But you oppose planting the filter layer.”

“Put external tissue into the central pipe and we can’t control it.”

Soren cut in.

“We waited for controlled mechanical filtration until the water stopped.”

Another resident said, “I reject both. Filter with sand and charcoal, without a Forge chip or Bloom membrane.”

“Flow falls to one third.”

“At least neither system commands us.”

The factions had no names yet.

But people were already choosing different futures through repair methods.

Selection did not end with a vote. They placed three models of the northern pipe and made every volunteer do the work.

The first was rusted metal. Mateo sealed it with a resin band and bolts in eleven minutes. Under pressure, the joint slipped after seven.

Hima tried to press the adhesive membrane on her arm to the pipe.

Jin said, “Using your body as material is excluded from the test.”

“Even with my consent?”

“In the field, exhaustion may change consent. If your arm leaves, the pipe opens again.”

Hima requested a biological-resin sample instead. It failed to cure for twenty-eight minutes, and nickel killed the edges.

Neither method passed alone.

A thin layer of Hima’s resin over Mateo’s bolts held pressure for forty-three minutes. They jointly signed the combined procedure without accepting each other’s method.

The second model tested contaminated-water filtration. The mechanical membrane had high flow but passed some spores. The biological membrane trapped spores but concentrated nickel in its tissue. Sand and charcoal reduced both, but flowed only nineteen liters per hour.

Soren said, “Put all three in series.”

“Not enough pressure.”

“Raise the pump?”

Jin displayed the test chip’s degradation range.

Minimum: 58 hours.

Maximum: 201 hours.

Above 57 percent output, the minimum fell to seventeen hours.

Perfect the filter and the pump died first.

They chose mechanical membrane and sand as the base, adding a biological layer only on the branch for external respiratory membranes. The water came from one pipe, but final filtration differed before it touched a body.

Hima said, “Separation will be called discrimination.”

Mateo answered, “Equality doesn’t require every body to drink the same water in the same way.”

Not an apology, but farther than the first meeting.

The third test was a nitrogen plug. Two volunteers ignored pressure warnings to finish within the target time and failed. The slowest stopped when the leak sound changed and passed.

They did not need the strongest person or the person most loyal to one method. They needed someone who stopped when stopping was required.

Jin made a six-day schedule.

Day One: inspect breaks and install temporary settling.

Days Two and Three: join six central-pipe failures.

Day Four: permanent nitrogen plugs.

Day Five: select and install filter layers.

Day Six: recover orbital wreckage.

Mateo asked, “If we don’t agree on filtration by Day Four?”

“On Day Six, flow is still sixty-three liters per hour.”

Hima said, “Vote.”

“One vote each means the dry wing wins even though bodies differ.”

“Then votes proportional to skin-water need?”

“Affected people must at least have a right to stop it.”

Before selecting people, the team had to choose how it would decide.

Rao entered with his palm wrapped in cloth.

“I’m not going.”

No one had asked him.

“I’m saying it before you ask if you need me again.”

Jin removed chemical sensing from the schedule.

“We measure with instruments.”

“If the instruments are wrong?”

“That cost goes into the schedule too.”

Rao nodded and sat by the door.

The final team contained four dry-wing residents, four external respiratory-membrane residents, four symbiotic transitionals, and two who refused to represent either side. They would field-test all three filtration methods at small scale and require a stop right from every affected group.

Departure: seven hours.

Travel: nine hours if rain stopped, fourteen if it continued.

Ian’s reversible interval on arrival: 9 days, 21 hours to 9 days, 16 hours.

After six days of repair, a little more than three remained.

If City Three’s equipment found no cause, he needed to return to City Seven’s Archive lab. Fastest return: twenty-two hours.

“I won’t stay through the repair,” Ian said.

Mira looked at him.

“When will you return?”

“After I check the recorder coordinate.”

“Is that more important than your hand?”

“Trying to decide for me again?”

Mira closed her mouth.

“I’m allowed to ask whether it matters.”

“Then I’m allowed not to answer.”

“Yes.”

Ian pointed at the field-key list. One of twenty-seven responded weakly.

FIELD KEY 09.

PROXIMITY POSSIBLE.

The recorder did not identify Ian as a sample. It might be reacting not to a biological key, but to a fragment of Archive authentication on his wrist.

“If we open this, can we know whether it’s mine?”

“We need to compare your medical data.”

“And if we don’t?”

“You can return without knowing.”

“Is not knowing a choice?”

“Yes.”

Ian did not open the field key.

At City Seven’s sealed shaft, citizen observation began.

Elias inserted the red handle into the lock. Mechanical teeth meshed inside.

Aegis warned.

USING SAFETY-BOUNDARY PRIORITY RELEASES LINKED ACCESS AUTHORITY FOR 7 LOWER ISOLATION AREAS.

Noah said, “It doesn’t open only this?”

PHYSICAL COMMON SHAFT.

NO SEPARATION FUNCTION.

The seven included the lower Archive, closed Bloom culture conduits, and the original records room of those transferred to City Three eleven years earlier.

“You knew turning it opened all of them?”

“Not full release. It opens locking authority.”

“Who uses that authority?”

Aegis answered.

EACH ADMINISTRATIVE LAYER.

Forge, Archive, Bloom, and Aegis could all open their own doors at once.

A lottery-selected citizen raised a hand.

“Can we lock it again afterward?”

UPPER PRIORITY CAN BE RECLAIMED.

IF LOWER LAYERS HAVE NOT PHYSICALLY OCCUPIED THE BOUNDARY.

“If they have?”

HUMAN APPROVAL REQUIRED FOR FORCED CLOSURE.

“Whose?”

SAFETY RESPONSIBLE PARTY.

Eyes moved to Elias’s hand. The tool that opened the doors and the right to close them belonged to the same person.

Noah painted a white line before the lock.

“No one inside this line before it turns.”

A medical committee member asked, “Why do you set the work line?”

“I’ve seen more places where moving doors kill people.”

Three outer-wall workers installed manual braces on both sides of the vertical shaft. If the powered locks released together, no one knew which way a door bearing forty-two years of load would move.

Noah tightened bolts with his left hand because two right fingers would not move. When a worker offered to take over, he handed over the wrench.

“Not something to turn alone this time.”

They sampled the air below first.

Oxygen: 8.1 percent.

Nitrogen: 86 percent.

Unclassified volatile substances: 2.4 percent.

Not air a living person could breathe at once.

An observer asked, “If that knocking is a person, how did they live in there?”

Archive answered.

POSSIBLE MECHANICAL DRIVE.

Bloom offered another answer.

POSSIBLE ANAEROBIC BIOLOGICAL DRIVE.

Forge proposed structural thermal expansion.

All three layers interpreted the same sound in their own language.

Elias said, “That is why we confirm.”

Noah placed a transparent seal over the red handle. Turning it would tear the seal and remain visible on the remote screen.

“Everyone sees when and how far you turn.”

“I approved public observation.”

“Don’t tell us you approved it. Show your hands.”

Elias released the handle and waited until every observer was in position.

The impacts below stopped.

Thermal imaging found no moving object. Acoustic sensors calculated the three strikes had been spaced exactly 2.6 seconds apart.

Too regular for natural expansion. Too slow for urgent human knocking.

Elias took the handle again.

“Stage One only.”

The red handle had three positions.

Stage One: release locking authority.

Stage Two: remove priority between isolation boundaries.

The Stage Three label was worn unreadable.

Aegis did not explain it.

DATA ACCESS RESTRICTED.

Noah asked, “Secret even from the person holding it?”

FUNCTION NOT REQUIRED TO KNOW.

“That makes me want to stop you more.”

Elias’s thumb touched the end of the handle, then withdrew.

He had not turned it.

Then three impacts rose from below.

Someone was knocking from inside.

At the same moment, the recorder’s moving coordinate updated.

The point 612 kilometers away vanished.

Its new location was thirty-four meters beneath City Seven.

Two untransferred coordinates had merged.
