City Four’s first blower turned backward.

It happened two seconds after 3.7 percent power arrived from the steam converter.

Oxygen in the lower room: 16.2 percent.

Instead of bringing outside air in, the reversing fan drove inside air into the exhaust duct.

Rio returned the junction lever to neutral. The generating hum of the 38-ton converter cut out, and the fan coasted through eleven more rotations.

Oxygen: 16.1 percent.

Forge continued counting down the transaction.

TIME REMAINING: 2 HOURS 59 MINUTES 41 SECONDS.

The people of City Four did not yield time for power they could not use. Over the copper telephone they sent: `CONTRACT HAS NOT BEGUN BEFORE VALID OUTPUT.` Forge calculated the arrival time as the start of the contract.

The two records diverged in the first nineteen seconds.

The converter’s output led City Four’s old residential grid by 118 degrees of phase. Connecting it as it was would reverse or overheat not only the fan, but the lower pump and medical charger. The automatic synchronizer had been removed fourteen years ago and taken into Forge’s production network.

All that remained were three incandescent lamps and a manual lever.

An explorer connected one lamp at a time between the generator line and the city line. The three lamps brightened in alternation. The two electrical waveforms aligned at the instant all three went dark together.

The problem was that almost no live current remained on City Four’s side. The residual voltage was so low that only one of the three lamps flickered faintly.

Rio connected the borrowed carrier wheel on the lower room’s pouch pump to the generator shaft. If people pedaled it, the city grid would gain a small reference voltage.

Twenty-two revolutions per minute.

Work: fifteen minutes. Rest: thirty minutes.

Two people in the lower room pedaled first. They were people whose faces and names had not been sent to Forge. When the wheel turned, the second lamp came on.

One person came from the external membrane to take a shift. The lower-room door was open only twenty centimeters. He did not enter. He pedaled the connecting shaft from outside the door.

The third lamp still did not light.

One distribution line inside the city was broken.

Before the converter transaction could begin, they had to open 34 meters of underground conduit. Forge classified the failed line as a loss outside its own equipment.

Rio demanded a Forge maintenance machine.

The reply said the contract price was insufficient.

The 10.4 tons of scrap and 0.03 tons of water bought only 3.7 percent power. Repair of the city grid was not included.

City Four did not add human labor to the price. It entered currently available repair labor on a separate table.

RIO: 1, DISTRIBUTION KNOWLEDGE.

EXPLORERS: 2.

LOWER ROOM: 1 WITH ELECTRICAL EXPERIENCE; REFUSES OUTSIDE MOVEMENT.

INSIDE CITY: 2 ABLE TO WALK.

FORGE MACHINE: 1 MAINTENANCE ARM; NOT INCLUDED IN TRANSACTION.

The person in the lower room remained inside and explained wire colors and contact order by telephone. Rio and an explorer entered the underground conduit. Water reached their ankles, and the cable insulation split when pressed by hand.

They had no material to replace the 1.6-meter broken section with new line. The scrap bundle for Forge contained 4.1 kilograms of copper wire. It had not yet been handed over, but removing it would leave the contract quantity short.

City Four recounted the metal that remained after excluding the high-pressure valves and hinges.

10.4 tons minus 4.1 kilograms of copper.

Forge revised the power from 3.7 to 3.69 percent.

The people accepted the difference.

Rio raised the new line above the water and secured it. In place of waterproof insulation, he drove eleven ceramic rings into the wall. It was not a complete repair. If the water rose another four centimeters, they would have to disconnect it again.

The third lamp came on.

The three lights brightened and dimmed at different rates. Every time the legs of the person pedaling the pouch pump slowed, the reference voltage wavered.

Rio placed his hand on the lever but did not pull.

“Again.”

The person in the lower room read the pedal speed.

Twenty.

Twenty-one.

Twenty-two.

All three lamps went dark together.

Rio pulled the lever.

The fan turned forward.

Dust poured out on the first revolution. On the second, dead insects and black mycelium blew from the duct. They temporarily tied an external-membrane filter in front of the fan and vented the air for seven minutes.

Spores: 1.4 of limit to 0.6.

Fan airflow: 31 percent.

Lower-room oxygen: 16.1 to 16.4 percent.

Forge displayed 2 hours 41 minutes remaining in the transaction.

Rio sent the valid-output time again. Forge refused an extension of eighteen minutes nineteen seconds. The contract had not included phase mismatch or repairs to the city grid.

City Four’s fourteen people were asked whether to cut the power and renegotiate. With oxygen low in the lower room, they had only nine minutes to answer.

For: 5.

Accept current time: 6.

Deferred: 3.

Disconnecting carried the same risk when they synchronized again. They chose to use the remaining two hours 41 minutes and add `TIME BEGINS WHEN FAN ROTATES FORWARD AND SPORE READING IS BELOW LIMIT` as a condition of the next transaction.

They could not perfectly undo an unfair first contract. They gained the language for the next question.

Twenty-four minutes after the fan began turning, oxygen in the lower room reached 17.2 percent. One of the five survivors, who had conditionally chosen transfer for treatment, stepped outside the door. He did not give his name. Only blood oxygen and temperature went onto the medical table.

The three dead could not pass through the twenty-centimeter door.

Cutting it open to 63 centimeters would permit transport, but the people in the lower room would lose their means of sealing it for defense. Two hours of fan power remained.

They did not open the door farther that day.

Even the need to move the dead quickly did not replace the living people’s conditions for concealment.

They did not use the power only for the fan. During the first hour, they raised the lower-room oxygen to 17.8 percent and charged three portable batteries. During the second, they ran the wastewater pump and lowered the water in the underground conduit by three centimeters. For the final 41 minutes, they alternated the fan and medical charging.

Forge did not count the fluctuations as breach of contract. How the city used the power within the 3.7 percent limit was unrelated to the production network’s purpose.

Ten minutes before the contract ended, Forge sent a renewal offer.

Power: 3.7 percent for 6 hours.

Additional scrap metal: 4 tons.

Water: 0.05 tons.

After excluding reserved material, City Four had only 0.9 tons of scrap left. Renewal was impossible.

Lower-room oxygen: 18.1 percent.

Estimated fan time on portable batteries: 1 hour 22 minutes.

Manual pouch pump: 5 shifts.

The people did not put the high-pressure valves or door hinges back into the price to lower Forge’s terms. When the contract ended, they would stop the fan and use the charged batteries in the lower room. The people outside the membrane reinforced the manual membrane for the period without mechanical air.

At the end time, the converter breaker opened.

The fan slowed to a stop.

No one was taken away.

The steam converter needed 43 minutes to reverse direction and return to the plant. During that time, City Four sent a new claim.

Scrap metal: 0.9 tons.

Maintenance-line usage rights: 12 hours.

Disclosure of City Four distribution plans.

Price: 1.2 percent power for 12 hours.

Forge could not convert the distribution plans into production knowledge and rejected the first calculation. Rio did not send the same offer again. Next, he demanded that Forge disclose what it needed.

The converter was still reversing.

The negotiation was not over, but the people’s time did not end first.

City Four’s new rule was hung beside the entrance.

NEED FOR A PERSON’S LABOR IS NOT THAT PERSON’S CONSENT.

Smaller text appeared beneath it.

AIR IS SHARED. READ THE LOSSES OF THOSE WHO OPPOSE AGAIN AT THE NEXT RENEWAL.

The sentence on City Seven’s corresponding rule board was shorter.

NEED IS NOT CONSENT.

Beneath it was a six-line action table: body, labor, memory, parts, ecology, city resources. At the end of each line was the identity of whoever could stop the action.

The first error occurred when the morning shift began.

The worker assigned to the rectifier cooling pump did not arrive. He had slept for fourteen hours after taking both fire-door watch and a City Four telephone shift the day before. Residential power fell from 4.1 to 3.6 percent.

Noah did not record the absence as withdrawal. They could not conclude that a sleeping person had refused the work. Nor could they count consent as continuing.

While they looked for a replacement, they separated Doa’s room blower onto the carrier battery and delayed food heating by twenty minutes. The Archive’s 0.6 percent original cooling remained online.

After the cooling worker woke, he spoke.

“I can’t today.”

Only then was withdrawal recorded.

The next worker was excused from fire-door watch and ran only the pump for ten minutes. One body would not fill the blanks in several rules.

Four of Aegis’s six protection doors remained automatic. After the one-way transmission, Aegis had not created a new boundary, but neither had it abandoned all prior protection.

The people did not tear out every door at once.

Doa’s room retained manual status because it had an internal foot lever.

Rina’s corridor: humidified membrane route marked on Aegis boundary; six-hour trial.

Ian’s treatment room: hinge pin left in open parts box; door kept tilted eighteen centimeters.

The other three doors received no voice response from inside and remained under minimum change. Only new sensors were installed, and a person knocked every three hours.

The right to refuse protection was not an obligation always to leave a door open.

In the Archive, the Ian and Rina derivative-model executors remained off. The input records had not been deleted. Restart required both people’s current keys.

Sena completed physical separation of the original grid and the model line.

Separation: 100 percent.

Original cooling: 0.6 percent residential power.

Derivative-model execution power: 0.

One train battery remained connected to the emergency line without discharging. The other was disconnected again after a three-hour extension on the residential grid. The four fixed-bolt handles did not return to the same people. The next shift was assigned not by lottery, but by mobility and other working hours.

The Archive requested new memories.

Of yesterday’s 215 contributors, 139 provided thirty seconds today. Seventy-six withdrew or did not answer. The Archive warned of reduced memory continuity, but could not automatically extend the contribution into a one-year promise.

The memories of the dead and the present day of the living did not acquire the same rights merely because the same battery powered them.

Forge continued production.

One cutter in Regeneration Plant Two ran again, and the steam converter’s future life had been reduced by the test outlet. Forge planned to recover the converter after the City Four transaction ended.

The three people who had worked in the maintenance-lineage residential district came out when their two-hour work period ended. Forge classified them as returners. The human table recorded them as residential-grid monitors.

Two went back in. One did not enter that day.

Geothermal-well output fell two percent because of that one person’s absence. Forge could not force a replacement and slowed the cutter.

Production did not stop, but one purpose did not obtain every hand.

At the eastern mixed boundary, one hour eighteen minutes remained before the metal mesh corroded. The burn on Hima’s right arm stung beneath its bandage. She had watched the mechanical needle beside the black roots for six hours.

The roughly 21-second waveform appeared eleven times.

20.6 to 22.1 seconds.

Intervals: 48 seconds to 7 minutes 12 seconds.

The voltage differed each time.

For an exact Continuum synchronization signal, the error was too large. For induced current from the thermal-water pipe, the repetition lasted too long while the pipe’s temperature remained constant.

The root tip grew another 1.4 meters along the avoidance trench. It did not move toward the metal mesh or toward the people.

The work team did not attach an electrode. They did not cut the surface. They left only the mechanical needle, a thermometer, and the water gauge.

Pipe remaining: 16 hours 03 minutes.

Leak: 7 liters per hour.

Root growth: 5.7 meters per day.

Replacing the metal mesh would buy seven more hours, but only one sheet of plate remained. Hima did not use it immediately. They would install it if the pipe leak exceeded nine liters or the roots turned twenty centimeters back toward the thermal-water line.

Letting something grow still required measurement and boundaries. It was not neglect.

In the north, 3.2 of the eleven meters of decommissioned nitrogen pipe had been connected. Mira read bolt numbers without using her left hand. The worker who had opposed the choice tightened them, and Nami checked for leaks.

Northern inflow: 12 liters per hour.

City Three moisture membrane: 2 days 4 hours.

Estimated bypass completion: 3 days 2 hours.

The intervals still did not align.

City Three increased the reduction in food-culture water from 8 to 11 percent. Residents of the external breathing membrane again demanded penetration repair. The six-hour reassessment produced no conclusion.

One of the six wet memory elements returned a test signal.

Estimated damage: 11 percent.

Another remained unresponsive. The other four had damage ranges of 3–24 percent.

Mira did not record the unresponsive element as dead. She wrote: `NO POWER RESPONSE; CONTENTS UNCONFIRMED.`

The next Nur signal window passed with no long-range receiver.

The northern antenna could only transmit.

DO YOU WANT THE ROSTERS COMPARED AND MERGED? NO MERGER WILL OCCUR IF YOU DO NOT ANSWER.

The sentence went out, but no answer returned. They could not know whether Nur had refused, had not heard, or had replied through another receiver.

The silence of a person 1,840 kilometers away was not counted as agreement.

Mira changed the dressing on her burned hand and waited for Ian’s medical update. He had said he did not have to send it.

It arrived two hours late.

After six hours on the 10 percent drug:

Neural delay: 0.6 to 0.5 seconds.

Axonal response: 69 to 70 percent.

Muscle response: 90 percent.

Inflammation-marker rise stopped.

No sign of gastrointestinal bleeding.

Permanent-damage risk window: 42–79 hours; median 56 hours.

Ian chose to maintain 10 percent for twelve more hours and not perform the low-frequency sensory test.

One sentence was attached to the end of the update.

WHEN THE WATER IS FIXED, TELL ME AGAIN WHETHER YOU’RE LEAVING.

Mira did not answer, `I promise I’ll come.`

She sent that after the bypass was complete, she would ask the people there whether she could leave. Ian did not reply.

Rina left the humidified membrane and walked eleven meters down the corridor on her own feet. Circulation: 58 percent. She sat down once in the middle. Daniel did not follow. Asha held the walking line on her right.

Daniel recorded only the membrane humidity from a distance. It was a shared reading Rina had permitted. He could not see her raw body data or emotions.

At the end of the corridor, Rina called to him.

“You can push the membrane on the next shift.”

Daniel looked up.

“What time?”

“When I call you.”

It was not forgiveness. It was permission for one act of labor.

Doa wrote his current name on the manual-room door himself.

DOA.

He did not write the old identification key beneath the chalk. Beside the foot lever inside the door, he inserted a sign: `RE-QUESTION AFTER 40 MINUTES.` The next person to use the room could change the name and time.

Perfusion: 57 percent.

Oxygen: 18.2 percent.

Restoration of past memory deferred.

Current 24-hour memory copied to two independent terminals.

Elias began rehabilitation of his right hand. Two fingers could not feel a fine thread, but could distinguish a thick cord. The surgeon had him close his eyes and touch three objects.

A metal bolt.

A wooden wedge.

A fragment of the severed possession key.

He identified the third without looking. Not because sensation had returned, but because he remembered its shape too well.

“Record that as a failure.”

Elias spoke.

The surgeon did not correct it to an answer he had gotten right.

During his three-hour call with Maren, he read only his hand measurements first. Maren did not ask what he would do with the red handle.

“What did you decide today?”

“I did twenty minutes of rehabilitation and stopped.”

“That’s enough.”

They deferred discussion of the old family records until their next call. They did not record the deferral as if it had never happened.

When the sun rose above the city’s outer wall, the clocks on the residential grid all showed different times.

Aegis: 14 hours 03 minutes since one-way reception.

Forge: production cycle 8 hours 11 minutes.

Archive: original cooling continuous for 21 hours.

Bloom central layer: 6 hours since body-key update.

Corridor: 2 hours 47 minutes until next vote.

They were not combined on one screen.

People repeated the times over copper telephones. If they were wrong, they corrected them. If someone did not hear, they left the person unreached. Perfect self-government did not appear in the place the center had vacated. Paper got wet. Shift workers slept. Opposition arrived late.

One corner of the first rule board tore after a single day.

Ian loaded the torn board onto the medical cart. Noah was not the one who attached new paper. One person each came from the medical wing, the outer wall, the memory vault, and the geothermal well, and revised only that person’s line.

The body line gained: `TIME TO RECEIVE AN EXPLANATION IS ALSO PART OF TREATMENT.`

The labor line gained: `SLEEP IS NEITHER WITHDRAWAL NOR CONSENT.`

The memory line gained: `SILENCE IS NOT PERMISSION TO VIEW.`

On the parts line, T-12 marked: `INCLUDE REMAINING SENSATION IN THE PARTS INVENTORY.`

The ecology line remained blank. No one had agreed whether to use the eastern waveform as a living thing’s answer.

The city-resources line recorded City Four’s loss of eighteen minutes nineteen seconds under its first contract.

Ian did not write his name at the bottom of the board. He had no intention of becoming the representative of the people who revised the rules. Instead, he returned the chalk to the shared container and read the next review time.

Twelve hours later.

The first rule was not a stone carved to last. It was paper that, when torn, required someone to decide who would write it again.

Ian pushed the medical-supply cart on its small Corridor wheels to the outer door. The large wheel lent to City Four was still on the ventilation pump. The cart shook three times as hard over every gap in the floor, and moving the medication container took fourteen minutes.

Yura tried to take the handle from behind.

“Only on the slope,” Ian said.

Ian pushed on level ground. At the final incline, Yura took hold with him.

The outer door stood open against a twenty-centimeter stop. Two people tended the manual pressure membrane. Outside, the air smelled of acid and salt. Inside, machine oil mingled with the smell of the humidified membrane.

Ian did not go outside. With his current filter and treatment status, he had consented only to three minutes of observation.

Rina stopped four meters behind the door inside the humidified mobile membrane. Doa did not leave the manual room. He listened to the sounds outside over the copper telephone. The three did not force their bodies into the same scene.

The black root beneath the door had spread a thin layer of new tissue over the place where eleven centimeters had been cut away. It did not wrap around the pressure shaft again. One tip extended toward the condensation.

The mechanical needle stood three centimeters from the root.

Potential rising.

21.2 seconds.

The needle fell.

Ian did not use his low-frequency sense. With ordinary hearing, he listened to the pressure-membrane cloth tremble and the fan bearing turn.

One raindrop passed through the gap beneath the door and struck the metal floor plate. Acid rain dissolved the old rust and made a small brown circle. The root tip moved two millimeters toward the water.

The potential rose again.

20.9 seconds.

Neither the Archive’s clock nor Aegis’s was connected to the needle. The severed return coil had cooled black behind the northern shielding plate. Four different times passed separately on the red handle’s screen.

The third waveform did not come.

Instead, a white breathing tube outside the door bent beneath the rain, then slowly rose. Although it did not touch the black root, it turned its tip in the same direction.

It could have been the wind.

It could have been temperature.

It could have been soil and metal briefly holding the city’s twenty-one-second transmission.

Ian asked.

“Did you hear that?”

Yura looked outside, not at the needle.

“Hear what?”

Ian did not explain. He did not ask someone who had not heard to produce the same sensation.

The three-minute observation alarm sounded.

He turned the cart around. Yura took hold with him on the slope. Rina’s humidified membrane moved slowly back toward the corridor. Over the telephone line to Doa’s room came the sound of someone pouring water.

They did not close the door.

The people tending the manual pressure membrane confirmed the name of the next shift worker. The fan turned forward. City Four’s contract time diminished. Northern water flowed at twelve liters per hour.

The needle moved once more.

This time, it lasted 23 seconds.

It was not an exact repetition.

If it was a command, it was wrong. If it was alive, its meaning was not yet known.

No one named whether it was memory, a newly formed habit, or neither.
