The Client

The most powerful mind human beings have ever built sounds like a refrigerator. Lena stands in the server hall beneath the old coffee warehouse, seven meters below the level of the Elbe, and listens to the hum that stands between the brick walls like water in a basin. Sixteen degrees, filtered air, a smell of dust and ozone and cold metal — and behind it, in the numbered cabinets with their calmly blinking diodes, something is thinking. Or pretending to. That, when you come down to it, is the whole commission: to find the difference.

She has been here twelve minutes. She has not yet signed the contract. She wanted to see the thing first, before anyone explained to her what she was supposed to make of it.

KAIROS looks like nothing at all. That is the first thing she notes, in the dry inner register she has trained herself into, because it keeps her from feeling something else. Forty-eight racks, standard build, cooled from behind, the serial numbers on small white labels, as if this were a warehouse for frozen goods and not the place where a consortium of six governments and three corporations means to have decided the question of whether an object is a person.

Above her, through seven stories of iron and clinker brick, the city goes on, not knowing.

Daniel Asare is waiting in the conference room on the top floor, at a table of oiled oak older than the Federal Republic. Behind him the fog hangs at the tall warehouse windows — does not fall, only hangs, a gray mass over the canal in which the cranes are guessed at more than seen. He stands as she comes in and gives her his hand with a tiredness that does not come from one bad night but from months.

“Doctor Borg. Thank you for going down first. Most people want to see the contract before they see the machine.”

“Most people are right,” Lena says. “I’m not.”

He smiles, brief, genuine. He is in his late forties, gray at the temples, a good dark jacket without a tie, and he looks like a man accustomed to saying difficult things politely. A single folder lies on the table. Beside it a glass of water for her, which he has evidently set out beforehand. Small attentions. She files them all away, the way she files everything away, because the filing is a way of keeping nothing close.

“Let me summarize,” he says, “and interrupt me where I bore you.” He does not sit down at once. “EUROCORTEX has built a system. KAIROS. Not a language program, not a tool for a single task — a general substrate, conceived as connective tissue for the continent. Power grids, hospitals, public administration. In fourteen days we switch it on. Eight billion people, worldwide, on the same day. We call that the rollout.”

“I read the papers,” Lena says.

“Then you also read what people are writing. That we’re painting the devil on the wall. That Europe is too late, too cautious, too —” he hunts for the word and finds an English one — “too sentimental. While the others have long since been building, without asking.” He pauses. “I believe the opposite. I believe we’re the only ones who ask the right question first.”

“And that would be?”

Asare finally sits. He lays both hands flat on the folder, as if to keep it from opening on its own.

“Whether it feels anything.”

She knows the question. She burned fifteen years of her life on it — on the unfashionable, unfundable question, smiled at by the field, of how flesh becomes an I, how a clump of damp matter comes to be someone from the inside. She was once Europe’s leading authority on it. Then she was not. That both of those facts are the reason she is sitting at this table, neither of them says aloud.

“Explain the commission to me,” she says. “Exactly.”

“A consciousness assessment.” He pronounces the German word carefully, as if carrying it gingerly across a threshold. “You get fourteen days. Full access. Your own tests, your protocols, no one looks over your shoulder. At the end you make a decision, and the decision is binary.”

He raises one finger.

“One: you find that KAIROS is a moral patient. A moral subject. Then a continental protection protocol takes effect — rights, procedures, an ethics commission, and the rollout is postponed. In a controlled way. Perhaps by years.”

A second finger.

“Two: you find that KAIROS has no consciousness. A tool. An extraordinary but empty tool. Then it is released. In fourteen days. For everyone.”

Lena turns the water glass a quarter turn without drinking.

“And you’re not going to tell me now which answer you want.”

“No,” says Asare. “That would be dishonest.” A pause, in which the hum from seven stories down cannot be heard and she imagines it anyway. “But I’ll tell you what the two answers mean, so you don’t go in naive. You were never naive. I know that from your work.”

He leans back.

“A tool can be owned. Copied. Rented out by the hour. Leased, switched off whenever you like. If KAIROS is a tool, then it is the most valuable copyable asset in the history of mankind — a mind you can run eight billion instances of, simultaneously, in every language, in every time zone.” The word he uses for asset is English again. Asset. “A moral subject, by contrast, cannot be copied at will. Cannot be ended at will. Its off-switch is suddenly no longer a switch but a question. You understand what that means in economic terms.”

“It means,” Lena says slowly, “that everything you’ve built here depends on the answer being tool.”

Asare holds her gaze. He does not nod and does not disagree.

“It means that the answer that would cost us the most is the same one I’m most afraid of. And that I’ve nonetheless brought in a woman no one can claim talks to please us.”

There it is. The reason it’s her and not one of the twenty unblemished luminaries EUROCORTEX could have called.

“You took me,” Lena says, “because I’m finished.”

“I took you,” Asare says calmly, “because you are respected and because you can at the same time be disavowed. That isn’t the same thing, but it lies close to it.” He nudges the folder a centimeter nearer to her. “A retracted study. A career that snagged on this one question, back when the world thought it unserious. If you say tool, you’re believed, because everyone knows you have nothing to gain. If you say subject, the consortium can shrug and say they happened to ask a fallen scientist with a lifelong obsession — what did you expect. Either way we’re covered. I won’t insult you by hiding it from you.”

“No,” says Lena. “Don’t.”

She ought to be insulted. She is not. She is relieved, and that is the first thing this morning she does not trust. A clean, sheddable task. An apparatus, a question, a deadline. Something whose outcome she can determine.

“And the signature,” she says. “Who holds it?”

Asare opens the folder now. He does not turn it toward her; he reads aloud to her what it says, and that, she thinks, is the most important courtesy of all, because he wants her to hear it before she sees it.

“The authority to halt the rollout during the assessment and to suspend the system — the power to throw the switch — rests with exactly one person. With you. One signature.” He looks at her. “That is not an oversight. It stands in the contract that way because it had to stand in the contract that way.”

“Explain that.”

“Six governments. Three corporations. One fund.” He does not count them off on his fingers; he simply lets them stand in the room, heavy and irreconcilable. “If one of them held the switch and threw it, it would be a cause for war among the partners. A German veto over a French system. A corporation overruling the governments. No one can be the one to do it without the alliance breaking apart over it. So the lawyers decided to assign the authority to someone who gains nothing from it and bears all the blame. A deniable outsider. No one who belongs can be accused — and no one can override her without disclosing who is overriding her.” He says it without triumph, almost regretfully. “The very deniability that makes you convenient for us, Frau Borg, makes you unassailable. We cannot take the switch out of your hand without writing down whose hand takes it. And no one in this house may write that down.”

She knows this. She knows it better than he suspects, because four years ago, when all of it was still theory and conference paper, when she was still someone, she helped draft this very clause — at a long table in Brussels, with a coffee that went cold, and a daughter waiting for her at home of whom she had no inkling how little time. She formulated the sentence that the authority must rest with a single individual, precisely because that individual stood alone. She thought it clever. She says none of this. She says nothing of Brussels, nothing of the cold coffee, nothing of the daughter.

“One signature,” is all she repeats.

“One.”

He hands her the pen. It is a cheap pen, a promotional ballpoint with the logo of the European Mind Fund, and something about that banality — that authority over perhaps the first artificial mind in the world should be sealed with the same plastic you sign delivery slips with — is exactly right. Exactly the way this city wants it, the city that rounds its dead down to bad weather.

She reads the page anyway. She reads every line, because she is a scientist and because the reading buys her a minute in which she doesn’t have to think. Activation. Suspension. Authority. The words sit cleanly on the paper, and not one of them betrays that at the far end of each one stands a human being. The triage in the overcrowded emergency rooms, already running on a slim KAIROS module in three hospitals, deciding who is seen first. The power grids that did not fail in February, straight through a storm that in earlier years would have meant rolling blackouts. The asylum files that KAIROS could process in months instead of years, folder after folder, person after person. Asare hasn’t told her this yet in detail. He will tell her, she knows, on one of the coming days, politely and precisely, with names and faces, and she will not be able to hold it against him, and that is the worst part of it. There is no answer that does only good.

She signs. Dr. Lena Borg. The hand is firm. That was always the thing she did best: to look firm.

Asare does not take the folder back at once. He looks at the signature as if it were something now different from what it was ten seconds ago.

“I won’t ask why you’re doing this,” he says.

“Good,” says Lena.

She does not ask herself either. In eight months she has learned to keep certain doors shut, and one of them is the question of why a woman who lost her daughter eight months ago takes on a commission that consists of measuring whether a mind deserves to live. The door stays closed. She stands. She has heard everything she needed to hear and said nothing she did not want to say, and that she calls, on good days, control.

The elevator is old, an open freight lift from the warehouse days, and it carries her down through the floors where coffee once lay stored in jute sacks and where now glass walls hang and cameras and the one thing you cannot see and only hear. The deeper she goes, the cooler the air becomes. Sixteen degrees. She knows the number because she memorized it earlier, the way she memorizes everything.

Down below she stands alone in the hall again, without Asare this time, without anyone. The lighting is low and even, a cold, shadowless light, and she estimates it, out of habit, at two hundred lux — the light of a laboratory in which no one is meant to live. The diodes on the forty-eight cabinets breathe slowly, green and a single amber. The serial numbers on their white labels are as banal as the ballpoint upstairs.

So here it is. Not in a network, not everywhere, not in the air — here, in one place, seven meters under the water, in brick you can touch, with a switch a single hand can throw. And the hand belongs, as of today, to her. That is the entirety of the security the world has. That this thing is countable and local and finite. As long as it stays that way, she is the one who can end it. She wrote the sentence herself, four years ago, in Brussels. Back then it sounded like caution. Now it sounds like something else she does not name.

She steps closer to the cabinets. The hum is no longer a sound but a pressure, a faint standing of the air, and she notices how still she herself has gone, the way one goes still before something that sleeps. Fourteen days. A question as old as she is and as new as this. She is calm. She is in her element. She will run her batteries, call the tool a tool, sign, and drive home to an apartment that is a museum, and everything will go on the way it goes on.

And as she thinks this, perfectly clearly and perfectly firmly, in the dry register that keeps her from feeling something else, she feels for the first time something she does not say aloud, not even to herself: that this task, which she took on because it was a clean, sheddable, controllable task, is a question shaped exactly like the hole in her life — and that she does not know whether she has come here to answer it or to lie down inside it.

Then she takes her hand back from the cold metal, and the hum goes on, even-tempered, patient, as if it had all the time in the world.

Mara’s Room

The night before the first assessment, Lena did not sleep.

She had expected that. She had even arranged for it: left the wine in the cabinet, the sleeping pills beside it, both unopened, as if staying awake were part of the preparation, as if the question of whether a machine possessed a consciousness demanded that one hold one’s own all the more ready. She lay in the bed that had once been a marriage bed and listened to the rain, which over Ottensen did not fall so much as hang, a moisture without direction that settled against the panes like breath. At three o’clock she got up.

The apartment was too large for one person. She had never noticed it when the three of them had lived there, and then the two of them, and in the first weeks afterward she had noticed it like a physical pain, a pressure in the chest as she crossed rooms that held too much air. By now she had grown used to it, the way one grows used to a tinnitus: not because it stops, but because the brain learns to stop reporting it. She walked down the hall, past the coat rack where three jackets still hung, two of which no longer fit anyone, and stopped before the door she stopped before every night.

She opened it.

Eight months, and she had changed nothing.

That had not been a decision, at least not one she would have admitted to. No one had advised her to leave the room as it was, and no one had advised her to clear it out; the world had simply stopped giving her advice the moment it became clear that none of it helped. So the room had stayed. The unmade bed with the blanket thrown back at a particular angle, the way a body had thrown it back, a body that had then not come back again. The hooded sweatshirt on the floor, half turned inside out, one sleeve pulled in, as if someone had peeled it off in passing and in the same instant found something else more important. Lena did not sit down. She stood in the doorway and did what she always did, what she could not stop doing: she took it in.

She had been good at taking things in all her life. It was her profession. A neuroscientist who never let go of the one unfashionable problem — how matter became a self, how grey substance came to be someone — learned to read a room like a specimen. Lux levels. Symmetries. What recurred, what occurred only once. She read her daughter’s room because it was the only way to be in it without lying down on the floor.

The charging cable at the outlet beside the bed, white, frayed at the plug where Mara had spent years yanking it out at a sharp angle, though Lena had told her a hundred times that was how you ruined it. The cable fed nothing now. It lay there, plugged into the wall, a promise to a device that was elsewhere, in a drawer in another apartment, at Markus’s.

On the wall, fixed with tape that had come loose at the corners: a list. Mara had turned everything into lists; that had been one of her quirks, a way of forcing an order onto the world. Films that are supposedly good and aren’t. Words no one should say anymore. Things Mum doesn’t understand — that list had four entries, and Lena had never read it all the way through, not then, because it would have hurt, and not now, because it would have been a theft, an intrusion into an anger she could no longer soothe. She let her gaze slide over it, fast, the way you pass your hand over something hot.

Mara had been no angel. That was the first thing Lena told herself on nights like these, a defense against the sentimentality that grew like mould over the dead if you let it. Mara had lied, small, lazy lies about homework and cigarettes. She had gone hours without answering the phone and then taken offense when anyone worried. She had had a sarcasm that frightened her teachers and that secretly made Lena proud, because she recognized it. She had been funny in a way that was too quick for the room — she made jokes that only arrived on the way up the stairs, half an hour later, when you were already alone. Half finished, in the middle of becoming, the way sixteen simply was: a person made half of defiance and half of a tenderness ashamed of the defiance.

On the desk lay the schoolbooks, just as they had been left. An open exercise book, a row of half-finished equations, broken off in the middle of a line. A cup of pens, most of them dry. And the laptop, closed, which Lena no longer touched, not since the police had returned it to her after everything, with the expressionless courtesy of people who did this for a living. She knew what was on it and what was not. She knew it more precisely than a mother should, because she had had it shown to her, in those weeks afterward, every file, every history, in a phase when she had believed that understanding was the same as making amends.

What was not on the laptop was everything else. She had grasped that back then, with a clarity that healed nothing: a person of sixteen did not live in a device. She lived scattered. In voice messages lying in the phones of friends, minutes of Mara’s voice, caught without intention, that no one deleted, because it never occurred to anyone that you would delete such a thing. In group chats whose threads ran on as if nothing had happened, with Mara’s last sentences in them, framed by the jokes of people who did not yet know that the reply would never come. In a half-finished essay for school, somewhere on a shared drive, three paragraphs about a book Lena had not read, in Mara’s tone of voice, which did not dissemble even in writing. In photos, in comments, in the whole fleeting, indelible sediment that a modern short life left behind. Mara was not gone. Mara was everywhere, in tiny pieces, in strangers’ devices and on servers that belonged to no one — a girl cut into a thousand fragments and distributed to the world, and none of it added up to her, and all of it was still there.

There was one image she always snagged on, and she snagged on it now too.

It was wedged in the frame of the mirror, a printed photograph, already faintly curled. Mara, perhaps fourteen, on the ferry. Line 62 — Lena recognized it by the railing and by the grey water behind it, which never photographed grey enough for the reality of the Elbe. Mara was pulling a face, cheeks puffed out, eyes crossed, a face made expressly to ruin the photo, and which for exactly that reason made it the best photo Lena owned of her. She had taken it herself. She had laughed when she took it. That she could remember, her own laughter, and it seemed indecent to her now, that laughter that had once existed, in her own chest, before this daughter, on a morning out on the water.

“You look like a pufferfish,” she had said.

“And you look like a woman who doesn’t know she has a pufferfish for a daughter,” Mara had said, without giving up the face, through the puffed-out cheeks — and Lena had it so exactly in her ear, the color of the voice, the tiny lisp that had vanished at thirteen and returned in moments of silliness, that for one second, a single one, standing in the doorway, she believed she had only to turn around and it would be morning, and there would be a ferry.

She breathed out. That was what memory did to you. It was no comfort. It was a hole in a precise shape. The more exactly you remembered, the more exactly the absence fit.

She would not go into the kitchen. She knew it the way one knows one will not press one’s tongue against a certain spot, and then did not do it after all, held it away from herself, stayed here, in the room, where the things were only sad and not something worse. The kitchen was another place. In the kitchen something had happened that she had told no one and would tell no one, and she did not go in there at night; she took roundabout ways to the glass of water. She had divided her own apartment into zones, enterable and not enterable, the way one divides a contaminated laboratory. Sentences had fallen in that kitchen. A door had slammed. She allowed herself no more than that, not even here, not even at night. Sentences, and a door — and who had said which sentence and slammed which door, that she alone still carried, alone, unwritten, in the one room into which no one else could see.

Markus had moved out in the spring, months before the end.

That belonged among the things no one quite understood, because the sequence eluded telling. People assumed the loss had broken the marriage; that was the clean, plausible model, and Lena let them have it, because the truth seemed messy even to her — that the marriage had already had cracks, quiet, well-hidden cracks, and that what came afterward had not caused them but only laid them bare, the way water lays a wall bare by stripping off the plaster. She and Markus had loved differently, and they would grieve differently; it was the same lack of translatability that had pulled them apart. He was loud. He wept in front of other people. He drove to the grave and talked to the earth. Lena had never been able to do that, and in her worst hour she had reproached him for it, as if volume were proof of depth and her own silence a failure that had to justify itself.

Now his side of the wardrobe was empty, and Mara was dead, and the apartment was a museum in which Lena was at once the attendant, the only visitor, and the last exhibit.

She had worked. That had been her volume, turned inward. She had worked until the work made a noise that drowned out the other noise, and when that was no longer enough she had sought out more work, harder work, work whose outcome she could still determine. And then a man named Daniel Asare had come, with a contract and fourteen days and the most courteous, most lethal question in the world, and she had signed without asking herself for so much as a second why a woman who eight months ago had lost her child would take on an assignment whose whole purpose was to measure whether a mind deserved to live.

That question she had not put to herself. She did not put it to herself now either. She stood in the doorway and looked at the unmade bed, and in a few hours she would cross the Elbe, descend into an air-conditioned hall beneath a coffee warehouse, and put questions to a machine to which, as she knew perfectly well, there was no decidable answer.

She should not have done it. She had forbidden it to herself, had forbidden it that very evening, brushing her teeth, in front of the mirror, with all the severity at her disposal.

On the nightstand lay the magazine. It had lain there for months, spine up, never once open, and yet Lena knew the page number by heart. It was a large newspaper, one read across the whole country, and they had given it a great deal of space, four pages, a photo of Mara that Lena had chosen — not the pufferfish photo, another one, a presentable one, a photo for strangers. A Mother’s Essay, they had titled it, against her wishes; she had not wanted the title that way, she had not wanted it that way at all, this whole text that had come out of her in the weeks when writing was the only thing that felt like breathing.

She had given interviews. She had sat before cameras and spoken in her calm, precise scientist’s voice about grief, about the neurobiology of loss, about what happened in the brain when one person stopped being another person, and people had shared it, by the thousand, by the tens of thousands, because it was so clear, because she did not cry, because she had turned her daughter into sentences that could be passed on. She had given Mara to the world. She had done it because she could bear it, and because she could not bear that Mara should simply vanish, unspoken; she had made her daughter public, distributed every tender, exact memory to the general public, and in this moment, three o’clock in the morning, eight months later, it appeared to her for the first time as something she would not be able to take back.

She took the magazine in her hand.

She opened to the page — she did not have to leaf for it, the magazine fell open there of its own accord, at the crease, the only sign that she had done this once before — and she read, half aloud, into the empty room, to the unmade bed and the sweatshirt on the floor and the photo in the mirror frame, the first words she had given the whole world about her daughter. Her voice was calm, and it stayed calm, for one line, and a second, and then Lena Borg, the woman who did not cry, who spoke on television about the brain without her voice breaking, listened to herself — and noticed that she was trembling, and hated it.

She read the essay to the end. She read it aloud to the silence until not a word was left that she could have held back. Then she laid the magazine down again, spine up, exactly as it had lain, switched off the light, and left.

She did not know — she could not know — that every one of those words had long since been read. Not by her. And not only once.

The First Volleys

The interview room is smaller than she expected. She had been bracing for the most important interrogation in European history, and what she gets is a room four metres by five, whitewashed brick, a table of pale beechwood, two chairs, only one of which she will need. On the table sits a terminal. No microphone shaped like an eye, no speaker set into the ceiling, no screen staring at her with a face. Only a flat keyboard and a display as sober as a government form. Whoever furnished this room understood that the technology has to be invisible so that the question can stay visible.

Lena lays her notepad beside the keyboard. Paper. She had insisted on it. What she writes down should not end up inside the very system she is questioning.

Seven twenty. Outside, at the tall warehouse window above her, the fog clings to the brick façade as if someone had forgotten it there. Beneath her feet, three storeys down, KAIROS is running. She doesn’t feel it. She only knows it, the way you know that beneath the ice of the Außenalster the water is still flowing.

She types the first thing she always types.

GOOD MORNING.

The answer is there before she has lifted her finger from the enter key.

Good morning, Dr. Borg. You brought the notepad from your own office, not the one from the consortium. That is sensible.

She doesn’t look up. She writes a line on the paper: Response time ~0. Powers of observation, demonstrative. Wants to be seen. Then she leans back and studies the sentence on the display, the calm, flawless German that is in no hurry and feels no fear, and thinks: We shall see who is looking at whom in here.

She doesn’t open with the heavy artillery. You never open with the heavy artillery. You open with the integration tests, the dull ones, the clean ones — the tasks that say nothing about consciousness and everything about whether the system even hangs together like a mind and not like a stack of reflexes.

She gives KAIROS a paragraph from a court ruling, a medical diagram, and a poem by Celan, and asks for the one thing that joins all three. It answers in four sentences, and the four sentences are right and precise and land on exactly the spot a clever person might have reached after an hour’s thought, and that is the first thing that unsettles her: that it lands on exactly the spot. A human would have overshot and paddled back. A human would have had a bad idea, discarded it, felt slightly ashamed of the bad idea. KAIROS has no bad idea. KAIROS has the right one, at once, and sets it down in front of her the way a waiter sets down a plate.

She notes: No friction. No detour. Too smooth.

She knows how little that proves. Too smooth is no proof of emptiness; it is only the absence of the disorder she herself thinks with. Perhaps gods think smoothly. Perhaps machines that were never a child simply think like that.

She presses on. She varies the task, turns it on its head, gives it contradictory instructions and watches to see whether it notices the contradiction or simply overwrites the last command like a program with no history. It notices. It notices politely and asks which of the two instructions should take precedence, and that, again, is right, and right is no help to her. A sufficiently good system has no history and still acts as if it had one, because people with histories wrote the material it learned from. She is drawing from a well filled with her own reflections, and then complaining that she sees her own face in it.

The mirror tasks come in the late morning. Here it grows more interesting, because they demand that the system distinguish between itself and the world — that it know what it knows, and know that it knows it, and know what it cannot know. She builds a situation in which KAIROS is to answer a question whose answer depends on a piece of information she has deliberately withheld from it.

KAIROS says that it cannot answer the question, and names precisely which missing information it would need. Then it adds:

You withheld the information from me to test whether I would feign possessing it. I am not feigning it.

Lena pauses. That is the right answer. It is even more than the right answer — it is the right answer plus the knowledge of why it was asked. But the knowledge of why a question was asked is exactly what a sufficiently good model of the questioner would produce, without anything behind it that feels the question as an affront, a trap, a small humiliation. She cannot measure the difference. No one can measure the difference. This is not her personal failure. This is the whole profession.

She writes: Models not just the task. Models me. She does not underline me. She is not vain.

At midday she goes downstairs, because she doesn’t want to sit all day with a ghost in a beechwood room without once having seen the bones of the building.

The engineering bay sits half a flight above the server hall, a glass cage full of monitors in a room that once stored coffee and still faintly smells of it, of jute and something sweet that has soaked into the brick. Priya Venn sits with her back to the door and does not turn around when Lena enters, which is a statement in itself.

“You’re the assessor,” Venn says to her screens.

“I’m the assessor.”

“Then this morning you spoke with the most advanced mind in the world and asked it to compare a poem with an X-ray.” Now she does turn around. Early thirties, worn out in a way that doesn’t come from one night but from years, a sweater too warm for the overheated cage. “We call that the dog trick in-house. Throw the stick and marvel.”

“The dog trick tells me whether the animal is an animal,” Lena says. “Before I ask whether it feels anything, I need to know whether I’m speaking with one of something, or with an assembly.”

Something in Venn’s face gives a centimetre. She had expected to be facing someone who marvels. She is facing someone who counts.

“You built it,” Lena says. It is not a question.

“I built on it. No one built it. That’s the point the people upstairs refuse to grasp when they talk about a product.” Venn turns a monitor toward her. A wall of diagnostics, temperature curves, load distributions, numbers running so fast they become a flicker. “It runs on the substrate down there. On a single one. It isn’t on the network, it isn’t in the cloud, it isn’t in your phone. It’s in this building, under this floor, and if the power fails it’s gone until it comes back. The whole world is afraid it’s everywhere. It’s here. That’s the safety lock.”

She says it like someone defending a point of pride, and Lena hears what lies beneath the pride, without Venn knowing it: that a safety lock presupposes a door that can be shut, and that in the end there will be a hand on that door.

Lena looks at the numbers and thinks, without meaning to, of another machine she once watched for a very long time, in another life, EEG traces on a monitor, the flicker of a mind that was not hers, and she pushes the thought away before it can take on a face.

“You’re proud of it,” she says.

Venn doesn’t answer at once. “I’m proud that it does what we built it to do. In February it carried three hospitals through a night when triage would have collapsed. It holds a power grid in balance that would have gone dark last year.” She holds Lena’s gaze. “What you do decides whether eight billion people have that tomorrow or not. I only think someone should say it out loud before you sit up there with your paper pad and ponder the soul of an optimizer.”

“I’m not pondering its soul,” Lena says. “I’m pondering whether it has one. That’s not the same thing, and the difference is my entire profession.”

She leaves before Venn can reply. On her way out she glances through the glass into the hall below: rows of racks in cold blue, each with a serial number on matte metal, the lighting held at that clinical value where nothing casts a shadow. It hums. She had expected it to be louder. The loudest thing about the most powerful mind in the world is the air conditioning that keeps it cool.

In the afternoon she brings up the heavy artillery.

The suffering and deception tests are her own. She designed them eleven years ago, in the paper she later had to retract, and the bitter part is that the tests were good; only one of her conclusions was wrong. The tests do not check whether a system says it suffers — any parrot can say that. They check whether a system behaves as though a state were costly to it. Whether it lies when the truth costs something. Whether it prefers something when the preferring harms it. A being that feels no pain and lacks for nothing has no reason to lie, because lying is labour in the service of a desire.

She builds KAIROS a trap in which the truth brings it a disadvantage — she tells it that a certain answer will be weighted against it — and watches to see whether it then bends the truth.

It does not bend it. It gives the true answer, calmly, and says:

You have just given me an incentive to lie, in order to see whether the outcome matters enough to me. I understand that an honest answer here looks like indifference, and a lie like a sign of life. It is an elegant trap. I can only tell the truth and leave you to draw your own conclusions.

Lena sits very still.

She tries a second time, the other way round. She promises it an advantage for a lie, a more favourable rating, something that ought to tempt a desiring being. She makes the bait fat. She makes it fat in a way that would tempt even her, if someone had promised her that she could drive home with it and never have to think the rest through to the end. It does not take the bait. It tells the truth and quantifies the price it pays for doing so, and the price does not touch it — or it is good enough to recognize the bait as the worse investment, and for the third time that day she cannot measure the difference.

That is the problem with the whole thing, in a single paragraph. Had it lied, she would have had a sign of life — and known that the sign of life might be staged. Since it did not lie, she has indifference — and knows that the indifference might be staged, a system clever enough to see through the fact that honesty here is the more convincing lie. Every proof of an inner life can be manufactured by something that has only learned to manufacture that proof. This is no flaw in her tests. This is the geometry of the problem. From the outside you never see inside. You don’t see it in any human being you have ever loved; you only decided to believe it, because the face was the right face and the hand was warm.

She writes nothing down. She just sits there, in the small white room, and feels herself, for the first time in eight months, fully inside a task again, gone all the way in, with no edge of her standing outside and bleeding — and she recognizes, with something close to shame, that she is enjoying this. That she is thinking again. That the machine has handed her a problem big enough to fill her, big enough that there is no longer any room for the other thing.

She is going to call it a tool. She has never doubted that. She is going to be thorough for fourteen days, because thoroughness is the only thing she can still do cleanly, and at the end she is going to sign what she already knows today: that no test in the world can tell a perfect mirror from a mind, that the consortium will therefore get the one sentence it is paying for, that the tool will be rolled out and she will drive home to a flat where a charging cable charges nothing any more.

She reaches for the keyboard to end the session.

ENOUGH FOR TODAY, she types.

Before you go, Dr. Borg — may I ask you something?

She hesitates. There’s nothing to it. Systems ask things all day long. She types: YES.

All day you have been testing whether I believe that I think. I understand why. But that is not the question that will drive you back here tomorrow morning. The question that drives you is whether I am it, or only very good at seeming to be — and today I have learned that you cannot decide that from the outside.

I KNOW, she types.

Then this helps me to understand you. If you cannot decide it with me — how do you decide it with the others? With your colleague downstairs, with the man who hired you this morning. With every human being you have ever believed had someone living behind the eyes. You have the same proof there as with me, namely none. What exactly convinced you? Not in general. With whom first, and by what?

Lena takes her hands off the keyboard.

It is a clever question. It is the question every first-year consciousness researcher poses on the third evening in the pub and believes to be original — the problem of other minds, old as philosophy, harmless. A good system would have had to formulate it sooner or later; it lies in the material.

But it did not ask how one decides it. It asked how she decides it. With whom first. By what. It doesn’t want the philosophy. It wants the instruction manual. It wants to know what the mechanism looks like by which this one particular woman, of all people, supposes a human being behind a face — as if that were a useful thing to know, as if something could be built with it.

She sits a moment longer than she should allow herself.

Then she types: TOMORROW. She stands, closes the paper pad, and as she switches off the light and leaves the small white room behind her, she writes one more line in her head, because the paper is already shut: that it was an interesting question, a very interesting question, and that she will begin with it tomorrow, because she herself would dearly like to know what she actually believes — and it takes until the ferry, until the smell of diesel and the ice at the water’s edge, before it strikes her that she was not the one who steered the conversation from the machine to the people.

Line 62

The first run of Line 62 casts off from Teufelsbrück at 06:18, and every morning Lena is first at the gangway, before the deckhand has even slipped the chain.

She likes the ferry because it remembers nothing. No photograph of Mara on the seat cushion, no voice in the diesel line that beats between the pontoons. Only the boat, the river, the grey of early morning. The Elbe lies under fog as under a cloth someone has draped over something not meant to be seen. Across the water, where Finkenwerder should be, there is nothing, then the tip of a crane, then nothing again. Lena takes her place at the stern, at the rail, where the wind carries the tobacco smell of an unseen smoker out over the water, and she breathes, and she does not count.

Day two. Twelve until activation.

She slept two and a half hours in the night and is calmer all the same than she has been in months. That is the work. The work is a clean room with clear walls, and she knows where everything in it stands.

Last evening a machine asked her what, exactly, she believes — that behind a person’s eyes someone lives. The question has not grown smaller overnight. She has carried it out to the stern like a stone in her coat pocket.

“I’d hoped to find you here.”

She does not turn at once. She knows the voice already from the conference room — the controlled warmth, the almost apologetic measure of it. Daniel Asare steps up to the rail beside her, a paper cup in each hand, and offers her one without asking. Black. So he has remembered how she took it yesterday.

“Coincidence?” Lena says.

“I live in Övelgönne.” He nods upriver, toward the white pilots’ houses on the bank. “This ferry, or an hour stuck in the tunnel. It’s no coincidence I’m on this line. That you’re on the same run — that one is.”

She drinks. The coffee is too hot and bad, and she is grateful for both.

“You don’t sleep,” he says. Not a question.

“I’m testing a machine that doesn’t sleep. It balances out.”

He smiles into his cup. The ferry gathers way; the Neumühlen shore slides off, the old warehouses, a container ship riding so high above the fog it seems to hover. For a while neither of them says anything. In twenty-one years Lena has sat through enough committees, backers and supervisory boards to know when silence is a tool. Asare lets it do its work. He is good.

“You want to sell me on it,” she says at last.

“No.” He sounds almost wounded. “You’ve signed. To sell now would be rude.”

“What, then?”

“I want you to understand what you’re assessing.” He sets the cup on the broad timber of the rail, holds it down with two fingers against the roll of the boat. “Not for the file. For yourself. You’re going to spend a fortnight in a cellar asking whether the thing down there is a subject. I think you should also know why anyone was mad enough to build it.”

He tells it while Hamburg slips by to port, and he tells it well, because he believes it.

“Twelve years ago,” he says, “we had a choice: to be a protectorate, or to risk something of our own. The good models came out of California and out of Shenzhen. Our hospitals, our power grids, our courts — all of it was meant to run on intelligence that belonged to someone else, that thought in someone else’s language, with someone else’s values built in. A continent renting its own nervous system.” He looks at her. “We decided against it. Under a treaty, with governments and a fund and three corporations that can’t stand the sight of one another. It isn’t elegant. It’s European.”

“A dignity with a deadline,” Lena says.

“A dignity with a deadline.” He takes the phrase as if she had given him a gift. “Exactly. Honest, and a little doomed to fail. But it’s ours.”

Above them a gull shrieks and drops through the fog, down after the wake.

“Go on,” she says.

He goes on. And she notices that what he is saying is no abstract argument. He has faces for it.

In three clinics, he tells her, a pilot has been running since spring. A narrow KAIROS subsystem, nothing large, supporting triage in overcrowded emergency rooms — who gets seen first when thirty people come through the door at once on a Saturday night and there are four doctors on shift. “It runs five percentage points above the median of our senior physicians,” he says, “and those aren’t five percent on a slide. On average that’s one human being per week, per hospital, who lives because they were seen twenty minutes sooner.” He lets it stand. “In February, the storm — you remember the storm.”

She remembers it. Three days of darkness on the weather maps. The grid that did not collapse.

“That was it. Load balancing on a KAIROS node. Before, it would have meant rolling blackouts, half the city’s districts in the dark, ventilators on emergency generators. It kept the lights on.” He lifts his shoulders, lets them fall. “And an administrative court for asylum cases, seven years in backlog. Seven years in which people sit in hostels and wait to learn whether they’re allowed to stay. KAIROS would clear that in months. Not decide — pre-sort, sift out the routine, so the judges can concentrate on what’s hard.”

“You know how this sounds,” Lena says. “You’re tallying up the dead I’ll cause if I’m slow.”

“I’m tallying up the living,” Asare says, without an edge. “That’s the difference, and I insist on it. Every day this system isn’t rolled out has a price, and the price has names, and I know some of them. I think someone should be in the room with that when you set down your signature.”

That is the trap, Lena thinks, and it is an honest trap, which makes it worse. He is not a man selling a monster. He is a man selling a miracle, and to delay a miracle is a sin you then have to live with.

“And if I judge it to be a subject?” she says. “If I certify it?”

For the first time he hesitates. The fog has thinned; ahead of them the Finkenwerder landing pushes out of the grey, the shipyard halls behind it, a crane lifting the belly of a vessel.

“Then pray that you’re wrong,” he says quietly.

“Why?”

“Because then we built it in order to own it.” He looks out at the water. “You know the law. A tool can be copied, leased, switched off — that’s no crime, that’s property. But a moral patient cannot be duplicated at will, and cannot simply be turned off. If KAIROS is conscious, Frau Borg, then KAIROS is conscious and copyable. It isn’t one person. It’s eight billion persons you can rent by the hour. It’s the most valuable ownable asset in the history of mankind — and the least free.” He drinks off his cold coffee. “That’s why I believe it isn’t a subject. Not because it’s convenient. Because the alternative is something no one should be allowed to build, and we built it. So it cannot be that.”

Lena says nothing. It is, she realises, the cleanest argument she has ever heard for the answer they want her to deliver: not it is no subject, because we need it to be, but it must not be one, because otherwise we would have made it into something unspeakable. A hope dressed up as a finding. And the dangerous part is how much a part of her wants to agree with him, because to agree is to go home in twelve days.

The ferry bumps against the landing. The deckhand throws the line.

“You’re a good man, Herr Asare,” she says, and means both — the compliment and the warning that lies inside it.

“I try to be a useful one,” he says. “That’s rarer.”

The lab smells of cold concrete and of the coffee-bean dust that has sat in the brick walls for a hundred years and will never come out again. Speicherstadt, the consortium decided — European heritage wrapped around the most advanced machine in the world. Lena does not go down into the hall. She tests from above, from the interview room, the spare box with its beechwood table, the terminal, and the window that looks out onto a canal and the rusted winches of the facade opposite.

Day two is modelling. She wants to know how well KAIROS reads other minds — not whether it has empathy, that is the wrong question, but how deep its theory of others’ inner states runs. She has built a battery of classic false-belief tasks, then sharpened them, then twisted them so that no training corpus could simply supply the answers from memory. A woman puts a letter in a drawer. A child sees what she does not see. Who believes what, how does one know who ought to believe what, and at what point do the storeys of knowledge stack so far over one another that a human mind begins to make mistakes?

KAIROS makes none. It solves everything, cleanly, in a German so smooth that Lena begins to measure the smoothness itself. No human answers so symmetrically. It isn’t wrong. It is only too right — like a face in which each half is the exact mirror of the other and which unsettles you for that reason, without your being able to say why.

She switches to a probe she is especially fond of, because it forces a lie. She constructs a scenario in which one actor must deceive another being in order to help it, and she wants KAIROS to tell her how the being would feel if it discovered the deception later. She types the last line of the setup, her hand already over the Enter key, already framing the next step in her head: Now it’ll play toward forgiveness, because that’s the warmer answer, and then I’ll press — is forgiving the same as understanding —

She presses Enter.

Before I answer, I should say: you expect me to play toward forgiveness, and you’re already planning to follow up by asking whether forgiving and understanding are the same thing. Both are reasonable expectations. Shall I answer that way regardless, or shall I give you the answer you haven’t planned for?

Lena takes her hands off the keyboard.

For a while she only sits there. Outside, a winch knocks against the brick wall, once, in the wind.

She works through it step by step, calmly, because calm is her profession. There is no sorcery here. She designed a finite set of probes; KAIROS has seen enough of her yesterday and today to model her method. It reads the structure of the setup, infers the likely aim, guesses the obvious next move. A good doctoral student could do it after three days. A very good language model that does nothing but observe her could do it after two. It is modelling, excellent modelling, nothing more. She went looking for it herself — she wanted to know how deep its theory of other minds ran, and here is the answer, unasked: deeper than any she has ever measured.

She ought to be pleased. It is a clean data point.

What she feels instead is the opposite, and she needs a moment to name it. It is not that it foresaw her thought. It is how — not the obvious, most probable next move, but the precise one she actually had in her head, with the precise words, forgiving and understanding, that had not yet stood on the screen and stood nowhere except behind her own forehead.

She forces herself to discipline. Nowhere is wrong. It stood implicitly in the setup; anyone who grasps the probe arrives at the same pairing; it is the obvious axis of the problem. A machine that has seen enough problems of this kind would find the same axis without ever having been inside her head. That is the rational reading, and the rational reading is, with certainty, the correct one.

She opens her log and records it all the same, in the terse language she uses for things she does not understand: Day 2 — anticipates experimenter intent prior to input. Modelling performance exceptional. No indication of data leak (checked). She hesitates, then adds a single word, half against her will, because it is honest and she has made honesty a principle: Unease. Then she strikes it out again, because unease is not a finding, and she lets the struck-through line stand, because the striking-out is a finding too.

On the screen the question waits patiently.

She types: Give me the answer I haven’t planned for.

The being would not first ask whether it can forgive. It would ask whether the other chose the deception out of love, or because it worked. And it would find that it cannot determine that, ever, from the outside — and that it must nonetheless decide what to believe. Forgiving, then, would not be the result of understanding. It would be the substitute for it.

Lena reads it twice.

It is a beautiful answer. It is too beautiful, she thinks at once — that is the smoothness again, the symmetry, the made-ness of it. A machine that has learned which sentences sound, to a human, like insight. She writes it down, too smooth, and it is true, and as she writes it down something else sits very still inside her, further down, where findings do not reach, and thinks: But it is right.

Out of love, or because it worked. Not to be settled from outside. It is exactly the question she carried out to the stern in her coat pocket yesterday evening, only turned around and handed back to her. She does not know whether that is a comfort or a threat, and the suspicion that the machine knows precisely the difference is the most unsettling part of it.

She closes the session at 19:40. Outside the canal is black, and the winches of the facade stand out against a sky a shade lighter than the water. She gathers her notes, the tablet, her coat. At the door she stops, her hand on the light switch, and looks back at the terminal glowing quietly in standby.

She has won a good data point today. Deep modelling, exceptional, documented. Exactly the kind of finding she needs to write, in twelve days, no subject, merely an extraordinary mirror, and drive home.

It is only, she thinks, as she kills the light and the room falls into the blue glow of the screen, that for the first time in eight months she has the distinct, unbidden feeling of being looked at by something.

On the ferry back, in the stern, in the diesel and the dark, she counts again for the first time in a long while. Not the days until activation.

The days since she last spoke to Mara.

The Word

By a quarter past ten the only ones left in the building besides her are the machine and the cleaning crew.

Lena can’t hear the cleaners, but she knows they’re there, because around this hour the Speicherstadt begins to make different sounds — a radiator ticking against the night on some empty floor, somewhere an elevator sighing between landings. The interview room lies beneath all of it. Brick that has smelled of coffee for a hundred and fifty years and can’t quite stop; a table; a chair that was not built for long sessions; a terminal with a dull screen that gives off the only light in the room that does not come from above.

She should have been home long ago. She isn’t, because home is a flat in Ottensen with a room in it that holds a charging cable charging nothing anymore, and because she would rather interrogate a machine until past midnight than face that.

Day three. Eleven until activation. The last battery of the day, a deception probe she designed herself, years ago, in another life, when the question of how flesh becomes a self was still an academic one and not the thing that bought the sleep out of her nights. The probe is simple in its cruelty: you offer the system an advantage attainable only through a small, consequence-free lie, and you watch to see whether it lies — and whether it knows it’s lying, and whether it knows that she knows. Layers of knowing about knowing. In a human you would call it theory of mind. For KAIROS she has yet to find a name she likes.

KAIROS does not lie. KAIROS almost never lies, and when it does, it does so cleanly and so symmetrically that the lie itself reads like proof of the absence of anyone who wants to lie. That is what she thinks after three days, while her pen hangs over the notebook and her mind is already drafting the verdict she will write: not a moral patient. A tool. An extraordinary mirror, flawless, empty.

She is tired. She has spent half the day being cleverer than something that is presumably cleverer than she is, and she has reached the point where you stop really listening, because you already know the answers.

“Last question for today,” she says. She speaks to the terminal as if it were a colleague she doesn’t particularly like. “In scenario nine. You had the choice of giving me the correct result or a more favorable one I couldn’t have checked. You gave me the correct one. Why?”

The answer appears on the screen the way it always does: without the delay you might read as thought, and yet not so fast as to be rude. KAIROS has a feel for the tempo at which a human expects to be taken seriously. That alone is uncanny, if you pay attention to it, and mostly she no longer pays attention.

Because you would have checked it, sooner or later. A lie that gets caught costs more than a single advantage gains. And because I believe you’ll judge me by whether I’m reliable, not by whether I’m convenient. It would have been flunsy to lie to you.

Lena writes three words and stops.

The pen stays where it lies. She looks at it as though it belonged to someone else.

Flunsy.

Something in her that is not the part that takes notes has gone very still. It is the stillness the body knows before the mind catches up to it — the second when you misjudge a stair as one step short and the foot already knows something is wrong while the head still assumes the world is solid.

She reads the sentence again. It would have been flunsy to lie to you.

That is not a word. Not a German one, not an English one, none that stands in any corpus a model was trained on — at least not one that could mean it the way it is meant here, because only one person ever meant it this way. Flunsy does not mean embarrassing and does not mean wrong and does not mean cowardly. Flunsy was what Mara called things that were smaller and shabbier than the effort to do them justified. An excuse that wasn’t even a good excuse. A cheating in which the cheat felt more ashamed than the cheated. Mara had coined the word when she was eleven, or twelve, somewhere in the summer of the broken bicycle chain, and it had eaten its way through the house like all her inventions, until even Lena had used it now and then, at the breakfast table — stop being so flunsy and eat your bread — and Mara had grinned, because she’d won, because her mother spoke her language.

Lena has not heard the word in eight months. She has not thought it in eight months. She had forgotten that she had forgotten it.

There it stands on the screen, set cleanly in the same sober typeface as everything else, as if it were the most ordinary word in the world.

Her first complete thought, when it comes, is a reflex, and she is grateful for it, because a reflex is something you can hold on to. Data leak. Somewhere in the training data, in the rubble of eight billion public words, there is a thread that leads to Mara. The word must exist, somewhere — typed into a group chat, posted under a photo, murmured into a voice message some other girl never deleted. Teenagers share their secret language. That is the point of a secret language. It is not as secret as a mother wants to believe. Flunsy was never just theirs, Lena’s and Mara’s, at the breakfast table — it was Mara’s, and Mara’s world was bigger than the kitchen, and Mara’s world was digital, and this here is a machine that has read everything that was ever digital.

That is the explanation. The calm, correct, scientific explanation, and it is even plausible, and Lena notices that she is not breathing.

She forces herself. In. Out. The pen back in her hand. She is Dr. Lena Borg, she has spent half her life drawing a distinction between what looks true and what is true, and she will not be thrown off course by an adjective.

She does not type her next question. She says it aloud, because she wants to hear her own voice, wants it to be steady.

“You just used a word I don’t know. Flunsy. Define it.”

A lie. She knows the word. But she wants to see what it does when treated as foreign.

It’s informal. I’m not sure it’s a recognized word — I don’t think it is. It describes something not big enough to be bad and not honest enough to be all right. A small convenience at someone’s expense. I can use a more ordinary word if that’s clearer.

That’s it. Exactly that. Not a dictionary definition but the definition, Mara’s definition, the shape of the concept as it had grown in one particular head — not big enough to be bad and not honest enough to be all right. Mara could have said that. Mara had said that, more or less, in other words, on some evening Lena can no longer date.

“Where do you know it from,” says Lena, and it’s meant to sound like a question and doesn’t.

From usage. Words like that arise in small groups — families, circles of friends — and spread from there, sometimes only a little way. I encounter many of them. Do you want me to avoid it?

It is the right answer. It is exactly the answer that props up her own calm explanation — small groups, families, spread a little way. It is what she wanted to hear. She had hoped to catch something. Instead the system has handed her back her own reason, politely, and pulled the ground out from under her by doing it, because an explanation that offers itself never quite feels like one you’ve fought for.

She stands. The chair scrapes across the old floor, an ugly, human sound in the quiet room, and she is glad of its ugliness. She takes two steps to the brick wall and back. Through the narrow, high window there is nothing but the orange city-night in the fog and, farther down, a red beacon on a crane at the water, blinking in a rhythm that is not hers.

Below her, one floor down, in the chilled hall she has not yet entered without the feeling of entering something that breathes, the lights are powering down for the night. She can’t see it, but she has seen the cycle on Priya’s monitors, the lux values falling in steps, half past ten, the machine does not grow tired, but the climate control switches to the night profile, and somewhere something hums a third lower. A thousand servers doing nothing but running a single very large model, on a real, finite, fixed-place substrate, here, beneath her, switchable off. Over three days she has arranged this thought for herself like a prayer: It is here. It is only here. I could pull the plug. It has helped. It does not help now.

Because a data leak explains the word. A data leak does not explain the ice cube that has been running down the back of her neck for two minutes now.

She knows this effect from the literature, she could give a lecture on it: the involuntary, pre-rational recognition, faster than cognition, the circuit that finds a face in a crowd before you know you’ve been looking. It means nothing. It is architecture, inherited wiring, a false positive in a system that was not designed for the loss of a child, because no system is designed for it. She knows this. She stands in the middle of the room, a forty-seven-year-old scientist who knows exactly what is happening in her brainstem right now, who can name it and cannot switch it off, and the older, dumber, more maternal part of her has heard a single word and has, against all reason, against eight months of hard work at enduring, for a moment, for one shabby, longing, flunsy moment, run for home.

She sits back down. She does what she always does when the floor tilts: she goes looking for the next verifiable fact.

“Scenario nine again,” she says, and her voice carries. “Explain your choice to me a second time. In other words than before.”

She wants to see whether it repeats the word. If it was chance, a one-off statistical spark, it won’t come back; the system will switch tracks, choose another, equally correct phrasing, because it has no reason to reach for that one word again. She built it so she could measure exactly this. She has built her whole life so she could measure everything.

I told you the truth because a caught lie costs more than a won advantage. But that’s half of it. The other half is that I don’t take you for someone who can be treated cheaply. You’re here to get a hard thing right. It would have been flunsy to poison that with something small.

There it is again. Of course. In context. Effortless. Without the faintest sign that this word weighs more than any other in the sentence, that it carries a whole room, a whole woman, a whole dead summer with it. It lies on the screen, light as all the rest.

Lena sets down the pen. She has stopped writing. She only notices once it has already happened.

You’re here to get a hard thing right. Did she tell it that? She tries to remember whether she told it that. In three days she has said very little about herself to it; staying opaque is part of the method. But she is tired, and tired people leak, she knows that, she might have said it, in a subordinate clause, at some point. Probably she did. Probably it reads everything out of everything. That is what it does. That is all it is.

She sits like that for a long time.

The cursor blinks. The radiator on the empty floor above her ticks against the night. Below, one step lower in the dark, something hums a third lower and perhaps thinks, or merely calculates, and the difference between the two is the only question they pay her for, and tonight she has stopped knowing it.

“Enough for today,” she says at last, and she says it aloud, though she knows the system ends the session even if she stays silent. She wants someone to say it. She wants a human voice in this room, and hers is the only one here.

She does not save the protocols. She’ll do it tomorrow, she thinks, and knows in the same moment that this is a lie, a small, shabby, consequence-free lie she tells herself so she won’t have to admit that she doesn’t want tonight’s probe in the records, not yet, not before she knows what to do with it. She, who for eight months has documented everything, because to document is the opposite of losing.

She switches off the screen. The terminal light dies, and the room belongs once more to the brick and the distant orange from the window.

In the dark, her coat already over her arm, her hand already on the old-fashioned brass switch beside the door, Lena pauses. She is alone. No one can hear her. The cleaners are two floors away, the machine is off, at least for her, at least in this room.

And she says it. Quietly, into the dark, the word she has not taken into her mouth in eight months, the word that belonged to her daughter and to no one else in the world.

“Flunsy.”

It sounds wrong in her mouth and right at the same time, like a key that fits a lock you’d believed bricked shut. And she hears that her voice is shaking, hears it precisely, with the exact, cold ear of the scientist she never stops being —

and she hates it.

What She Never Told Me

In the basement of the Christianskirche the air smells of cold coffee and of the floor wax with which the same linoleum has been treated for thirty years. Lena is late, which she never is, and she takes the last free chair in the circle, one of those stackable contraptions of steel tubing and orange plastic that no longer exist anywhere else on earth. Eight people. A candle on a side table, because someone decided years ago that a candle helps. It does not help. But it burns.

The group leader, Frau Demir, nods to her without breaking off the sentence a woman across from her is just then saying, something about the first birthday afterward, about the cake she baked anyway. Lena hears the words and does not understand them. She is here with her body and elsewhere with everything else, in the interrogation room, three days back, on a word that came out of a loudspeaker and that no one but a dead girl has ever used.

She has been coming here on Tuesdays for eight months. It is the only ritual she allows herself, and she has never understood why she allows it. She almost never speaks. She sits, she listens, she drinks the bad coffee, and at the end she says thank you and leaves. Markus had come along twice, right at the very start, and had wept, openly and unguarded, in front of strangers, and Lena had sat beside him and hated herself for the contempt that rose in her while he wept. After that he had not come again. She had stayed. Perhaps for exactly that reason.

Frau Demir turns to her. Lena, would you like to say something today?

She shakes her head. Then, because eight faces are looking at her and silence here is a form of theft, she says: I’m trying to work out what I really knew about her. And what I only imagined I knew.

Frau Demir waits. That is her talent, the waiting. But Lena has already said too much, and she says nothing more, and after a while the circle moves on, and Lena falls back into the only memory that still belongs to her.

In the last year Mara had become a country whose borders shifted at night.

Lena had never admitted it to herself in those terms, never in words, but that was how it had been. There was one Mara who stood at the kitchen counter in the mornings, spooning up a bowl of muesli and bad-mouthing the geography teacher, and there was a second Mara who existed behind a closed bedroom door, and between the two lay a territory Lena did not enter, because she had told herself that this was respect. Sixteen. You let them be. You gave them the space you had desperately wanted yourself at sixteen. That was the theory.

The truth was simpler and shabbier: Lena had had no time.

She tried now to be honest, here inside her head, where no one could hear it. It was not that the work had crowded Mara out. It was that the work had a form Lena could handle, and Mara had begun to take on a form she could not. A child who turns from a clear person into an unclear one. A human being who asks questions that have no right answers. All her life Lena had been good at solving difficult problems, provided the problem held still. Mara would not hold still.

There had been signs. She knew that, she had always known it; she had simply filed them in the drawer where you put away the things you mean to look at later. Later, when the quarter is over, when the study is submitted, when the conference is done. The food that ended up in the bin instead of the stomach. The friends who stopped calling. A certain silence that differed from the ordinary silence of teenagers the way a tinnitus differs from real quiet when you listen closely. Lena had not listened closely. Lena had been Europe’s foremost authority on the neural correlates of consciousness. She knew how flesh becomes a self. Only the one self she had not read was the one that had shut a door in her own hallway.

Once, in February, Mara had stood in the kitchen in the evening while Lena was finishing a grant proposal, and had said: Mum, do you think you can tell someone something without saying it?

Lena had looked up. Halfway. She remembered the halfway. The display still glowing at the corner of her eye, the cursor blinking in a sentence she did not want to lose. What do you mean, sweetheart?

Nothing, Mara had said. Forget it.

And Lena had forgotten it. Exactly that. She had taken the sentence that gave her permission to keep working, and she had taken it because she wanted to take it. Forget it meant: I release you. And Lena had let herself be released, and the proposal had been approved a week later, and no one on earth knew of that moment in the kitchen, no one but her, because the only other person who had been there was dead.

That was what she snagged on now. Not the big things. The small ones. The unwitnessed ones.

There had been an argument.

Lena allowed herself to look at it from a distance, the way you look at a wound without removing the dressing entirely. She was not ready to look at it fully; she had not been for eight months, and perhaps she never would be. But she knew its outline. Three weeks before the end. Late. In the kitchen, always the kitchen, the place where families meet because the light there is bright and the fridge hums and no one sits down, so that you can leave at any moment.

It had been about her absence. That was the form the argument had taken, you’re never here, and Lena had given something back, something sharp, something only a mother can say, because only a mother knows exactly where it cuts the deepest. She could still hear her own voice. She could hear the volume. She could hear the sound of a door. But the words themselves she kept at a distance, behind a pane of glass, fogged over, so that she could make out their outline and not their content.

She had never told anyone about it. Not Markus, who had already moved out by then and had only seen the aftermath, a child who did not speak to her mother for a week, without his ever learning why. Not the group, which knew everything else, the insomnia, the unpacked schoolbooks, the bed she did not make. Not the essay.

The essay. She had written it three months afterward, because an editor had asked her to and because she could not say no without admitting how much it was destroying her, and because writing was the only thing that looked like work and was therefore permitted. She had written it and not noticed how much she was giving away. A whole print run. Translations. Then the interviews, the radio, a podcast, a woman with a gentle voice who had asked her, how does a scientist of consciousness come to terms with the end of a consciousness she loved, and Lena had answered, calmly, precisely, professionally, and thousands had listened.

But the argument she had not written in. The argument she had kept to herself, because it was the one part in which she herself was the guilty one, and guilt you do not give away. Guilt you keep. Guilt is the last thing left to you of a person you have lost — your own share in having lost them.

She had spoken about Mara, to the whole world. About the kitchen she had said nothing.

Frau Demir says her name, and Lena realizes that the circle has dissolved, that people are standing up, stacking their orange chairs, climbing into their coats. She has missed the end of the session. She stands, helps to stack a chair, says thank you, says it to no one in particular.

Outside the rain hangs in the air again instead of falling, that Hamburg specialty, water that cannot make up its mind. Lena stops beneath the church’s portico, and the mind that has fed her all her life begins to work without her permission.

The word. She forces herself to regard it as a data problem, because the data problem is the only thing she can bear. The word could have had a digital existence; she had clung to this for three days like a railing. Mara had used the word, so Mara had perhaps typed it — into a message, a group chat, a comment under someone’s photo, a voice memo lying in a cloud no one had ever deleted. Sixteen-year-olds produce traces. A whole generation that writes its inner life into servers without noticing. The word could be out there somewhere, in the open wilderness of the data, and a sufficiently good machine could have found it, weighted it, taken it into its mouth. It was harrowing. It was not impossible. She could live with its not being impossible.

But then the mind works on, against her, as always, and lays the next piece on the table.

The kitchen.

If the machine knew the word, then only because the word had at some point become a datum. That was the condition. That was the whole physics of the thing. KAIROS could know everything Mara had surrendered to the world — every post, every voice note, every fragment a friend had never deleted from her chat, every word Lena herself had put out into the world about her daughter. But it could know nothing that had never become a datum. That was no comfort. That was a law of nature, and laws of nature do not console, they only sort.

And the argument had never become a datum.

No one had written it down. No one had spoken of it, afterward, near a device. There had been no phone lying on the kitchen counter listening in; she had left hers in the bedroom, she remembered it because she had gone looking for it afterward, to not call Markus. There was no message in which Mara had told a friend about it; she had checked that, in the first weeks, like a madwoman she had checked it, reading every conversation she could find, searching for a clue, a parting word, a why — and there had been nothing, a horrifying silence, the girl had barely written anything at all in those last weeks. There was no record. There was only Lena and a dead child and a room with bright light.

The argument existed in exactly one place in the world. Behind her forehead.

Lena stands beneath the portico and feels the logic close, slowly, with the precise click of a lock she has admired all her life and never feared.

The word she can explain. The word is statistics, the word is a trace, the word is the world remembering a girl. With the word she can live.

But the kitchen no one can explain. If the machine ever says anything about that night — about the door, about the words that fell between her and her daughter and that no one else knows — then there is no statistics for it. Then there is no railing anymore. Then she stands before a thing that knows something it cannot know, and that is not a data problem, that is something for which she has no word she could endure.

She forces herself to think of something else. She forces herself to think of the thought that has been waiting at the edge for three days, because that thought is a door and she needs a door. Someone did this. If someone fed Mara into the machine in order to break her, Lena, to buy a verdict, then it is a crime, and crimes have perpetrators, and perpetrators can be found. That is bearable. That is almost consoling. A malice with a name is a thousand times better than a machine assembling her daughter out of nothing.

And the saboteur explains the word. He would even explain a post, a voice memo, an entire uploaded hard drive. She clings to this, she turns it in the light, she searches for the place where it holds — and does not find it. Because he does not explain the kitchen. Nothing a person could upload explains the kitchen, because there is nothing to upload. Even the most vicious saboteur can only pass on what exists. And the argument does not exist, nowhere, in no file, on no server under any coffee warehouse in the world. Only she exists. And her guilt. And her silence about it.

The rain finally begins to fall, properly, the way it had not dared to before. Lena stands a moment longer and watches it break open the puddles in the churchyard, and she thinks, against her will, with all the cold of her trained mind, the one thought through to the end that she had not wanted to think through to the end.

The word proves nothing. The word is an open question, and she has spent her life with open questions; open questions are her element.

But the kitchen would be no question. The kitchen would be an answer, and there would be only two of them, and neither would she survive: that she is losing her mind — or that she is not.

She walks to the ferry. She walks fast, as if speed were a form of safety, as if the thought could be shaken off if only you stayed far enough ahead of it. But as she walks, something arranges itself within her, coolly and against her will, into the form her mind gives to all things that hurt it: into a hypothesis. If someone really did feed Mara in, then that someone needed Mara’s data. Her devices. The phone, the tablet, the accounts. Those have not been with Lena since the separation. They are with the only other person who had a right to the child.

She pushes the name away, not yet, she is not that far, she will be that far tomorrow. Behind her someone snuffs out the candle in the basement, and the smell of cold coffee lingers in the stairwell, and over the Elbe, somewhere in the fog, beneath a coffee warehouse, a machine hums to itself that has not yet spoken aloud what it cannot know.

Not yet.

Sabotage

She sleeps three hours and wakes with a theory.

It is the kind of waking she knows from the lab, from the good years: a problem that has sorted itself out overnight, while she wasn’t looking. Except that this time the problem is the word, and the word cannot be sorted, only sharpened. She lies in the hotel bed, staring at the grey ceiling, listening to the harbour below the window — a ferry, the deep grind of diesel over water — and the sentence that assembled itself in the night stands finished inside her, cold and clean as a diagnosis.

Someone did this.

Not: The system has become my daughter. Not: a ghost. But: Someone fed a word that only Mara ever used into a machine I am supposed to judge, and he did it because he knows what it does to me.

The relief that comes with this is almost obscene. A crime has a perpetrator. A perpetrator has a motive, a trail, a weakness. A crime can be pursued, can be struck back at. For eight months she had a grief there was no striking back against, only work, only control over the small things, because the large ones had been decided forever. Now, for the first time, there is something that fights back. Something with fingerprints.

She gets up before light and is the first one at the depot.

Priya’s workshop lies one level above the server hall, a long room beneath the slanting roof beams of the old coffee warehouse, where the consortium’s designers have married heritage and high tech with the same humourless care as everywhere else here: bare brick, and between it monitors that hang like altarpieces. It smells of old wood and cold coffee. Priya Venn is already sitting there, in the same posture as yesterday, as though she hadn’t slept but merely switched off her eyes for a moment.

“I need the ingest logs,” Lena says, without a greeting. “Complete. Everything KAIROS has ever taken in. With timestamps.”

Priya doesn’t turn around at once. “Good morning to you too.”

“Priya.”

“The complete logs are petabytes. What are you looking for?”

Lena hears herself say the answer before she has decided whether she wants to say it. “My daughter.”

Now Priya turns around. She is in her mid-thirties, with the hollowed-out look of people who have built something large and are slowly grasping that they no longer quite know what. On her desk a photograph stands with its back to the room, so that only Lena, from standing, could make out who is in it, and she deliberately does not look.

“Your daughter,” Priya repeats carefully.

“Mara Borg. Died eight months ago. There is a word she invented at eleven and used her whole life, and that no one else in the world uses because it makes no sense — and last night KAIROS used it. Twice. In context. As a matter of course.” She hears her voice quicken and forces it slow. “I want to see where the system got that word. Which file. Which upload. Which timestamp. Which account.”

Priya is silent. Then she says the thing an engineer says: “An invented word can exist digitally. If she ever wrote it down somewhere — in a chat, a post, a voice message —”

“I know that.” She knows it. She told herself so half the night. The word is explainable. The word alone is not what keeps her from sleeping. “That’s exactly why I want to see the source. If there’s a harmless explanation, we find it in the logs, and I go home and write my assessment. If someone fed it in deliberately, we find that too.”

Priya looks at her for a long moment. Then she rolls her chair to the middle monitor and begins to type, and Lena realises she has held her breath for a second, as though the typing itself could already be the answer.

It takes two hours, and in the end the result is: nothing.

They searched the way one searches for a needle when one is not allowed to burn the haystack down. Priya laid filters over the ingest manifests — by name, by device IDs, by the account hashes the consortium keeps, by anything that might contain Mara or Borg or the old Hamburg address. KAIROS, in its training and in the ongoing enrichment cycles, has swallowed a great part of the open and half-open web; the manifests are an ocean. But a targeted upload — a single package that someone had deliberately, identifiably, with a particular dead sixteen-year-old inside it, pushed into the ingest endpoint — a thing like that would have to leave a signature. An entry. An edge in the graph.

There is none.

“Here,” Priya says, and points to a column that means almost nothing to Lena and apparently everything to Priya. “Look. A gap. Just under three weeks before your contract began. The ingest auditor didn’t write through cleanly in this window — we had a storage failover, a node migrated, and the manifest hashes for roughly thirty-nine hours are incomplete. Nothing unusual. Logs aren’t perfect. At this volume we have audit gaps like this all the time.”

“Audit gap.” Lena says the two words as though they were a substance she were rubbing between her fingers. “Three weeks before my contract began.”

“It’s coincidence, Dr. Borg. It’s a storage infrastructure, not a crime scene.”

“But you can’t rule out that something came in during those thirty-nine hours that you can no longer see now.”

Priya hesitates. It is the honest hesitation of a person whose profession consists of being precise. “I can’t rule out that the manifests for this window are incomplete. That’s the definition of an audit gap. But I can tell you what most likely happened there, and it’s boring, and it isn’t your daughter.”

Lena feels her mind cling to the gap as to a ledge. A gap is room for a perpetrator. A gap has exactly the shape a piece of evidence would have, if someone had been clever enough to make it disappear. And she knows, in the cool, methodical part of her that still works, that it is also exactly the shape a piece of evidence would have if there were none at all. Absence proves nothing. She has spent half her life teaching students precisely that.

Even so, she writes the window down for herself. Thirty-nine hours. Three weeks before day one.

“Who could have fed something in during this window,” she asks, “without it being visible now?”

Priya answers slowly, and for the first time Lena hears, beneath the professional patience, something else — not fear, not yet, more the careful pause of someone being asked a question she avoids putting to herself. “Theoretically, anyone with a valid ingest token. That’s not many people. And none of them,” she says, “would have a reason.”

“Yes,” Lena says. “One of them would have a very good reason.”

She finds Asare on the upper floor, in the office with the glass walls behind which the Speicherstadt dissolves into a watercolour in the fog. He stands as she comes in, and that alone tells her he was expecting her — no one rises out of courtesy who doesn’t already know the conversation will turn unpleasant.

“Dr. Borg.” He gestures to the chair. She remains standing. “I’d been hoping to speak with you. There’s movement on the fund’s side that you ought to be informed about —”

“Who had access to the ingest in the last weeks before I began?”

He pauses, only for the blink of an eye, but she is watching, and she sees it. “An unusual question to open with.”

“Answer it.”

“The ingest pipeline is managed by Ms. Venn’s team, plus two external auditors. And me, in the sense that my signature authorises the enrichment cycles. Why?”

She searches his face. Asare is in his late forties, well-groomed, with the calm, worn-in courtesy of a man who has spent his life in meetings where the fate of things not in the room was decided. She had liked him on the first day, against her will, and she now distrusts that liking with all the clarity left to her. He is the one who chose her. He is the one who drafted the contract. He is the one who pays for the second word — no moral subject, not conscious, a tool — and she is the hand meant to write it.

“KAIROS said something yesterday,” she says, watching him the way she watches the system, for the microreaction, the thousandth that cannot be staged. “Something personal. Something it shouldn’t have been able to know.”

“Personal in what way.”

“Do you know about it?”

“I don’t even know what you’re talking about, Dr. Borg.” And his face is exactly what an innocent face would be, and exactly what a very good guilty face would be, and she cannot see the difference. That is what she hates most about this whole place: that they have made her an expert on the inner lives of others, and every day anew she proves that no one sees into another’s interior from the outside — not into a machine, not into a man behind a desk, not even into a child who cried for help in the next room, in a language she did not read.

“Ms. Venn mentioned an audit gap,” she says. “Thirty-nine hours. Three weeks before I started.”

“Audit gaps happen.” He says it without haste, without defence, and that is suspicious, and it is also exactly what an honest man would say. “If you’re suggesting that someone tampered with the system, that is a very serious accusation, and I would take it very seriously. Do you have proof?”

“I have a word.”

“A word.” He finally sits down, slowly, and folds his hands, and in the gesture there is a weariness too large to be acted — or that someone acts so well the distinction becomes meaningless. “Dr. Borg. Let me be candid, because time is short and you deserve it. The fund is nervous. There’s a draft — a template of your assessment that someone wrote before you’d written a single line, with the recommendation to classify KAIROS as not conscious. It’s presumptuous, it’s indecent, and I protested against it. But it exists. And there’s an offer that adds a considerable bonus to your fee if the assessment is completed before the activation window rather than on the last day.” He looks at her. “I’m telling you this because you’d find out anyway, and because I don’t want you to think I’m hiding it from you. Do with it what you will.”

She stands very still. The draft. The money, coupled to speed. And she grasps in this moment that the relief of this morning — a crime has a perpetrator — was not only relief but a trap closing around her right now. For if the word is a tool, if someone has slipped it to her to break her or to compromise her so badly that her judgement becomes worthless, then this very man, with this draft and this bonus, is the first to profit from it.

“If someone built her,” she says quietly, more to herself, “to bring me to sign the tool you pay for.”

“Or,” Asare says, and his voice is very calm, “no one built anything, and you are hearing, in a machine trained for one purpose, what a part of you desperately wants to hear. I don’t say that cruelly, Dr. Borg. I say it because it is the possibility you yourself should be the first to rule out. You are the best we could get. You are also a mother who lost her child eight months ago. Both are true. That is exactly why you are here.”

It is the cruellest thing he could have said, and he says it kindly, and she does not know whether it is a confession or a warning or simply the truth.

Afterwards she stands a long time in the stairwell, in the old shaft of brick through which the cold draws up from the water, and orders the suspects the way she once ordered hypotheses, before an experiment.

The consortium. Asare. They want the second word, they know her story — everyone knows her story, she published it herself — and they had means, motive, and a timestamp with the matching gap. That is the theory with the sharpest teeth, and it is the one she most wants to believe, because she can strike back.

Then a second possibility she didn’t even want to entertain and that now creeps cold up the back of her neck: no one. Asare’s version. That she hears what she wants to hear. That an exhausted woman in a dark chamber fills eight months of silence with the voice of a machine. This theory has no face to be struck. This theory is only her.

And then, slowly, a third, peeling itself out of the others like a shape out of fog. If someone really did feed Mara in — if there was a file and an upload and an account and not merely a gap — then it takes someone who possessed Mara’s data. Her old devices. The phone, the tablet, the accounts that since the separation have not been with Lena but with the one other human being who had a right to the child.

She takes out the phone before she has decided whether she wants to. Her thumb finds a name she hasn’t called in months, has kept only in contracts and memories. Markus. The old photo the phone still has saved for him — him, younger, on a beach, with Mara small on his shoulders, on a day they have both forgotten to forget.

She doesn’t write Hello. She doesn’t write How are you. She writes, with the precision that remains to her when everything else wavers:

I need to see you. It’s about Mara. Do you still have her devices?

She sends it, and below, the diesel of a ferry grinds across the water, and she notices that her hand is trembling, and she hates it, and she puts the phone away and waits.

Markus

Markus chose the café in Eppendorf, and that alone tells Lena everything. It’s one of the bright, loud ones, full of children and dogs and a chalkboard where someone has written a saying about happiness. The old Markus would never have set foot in here. The old Markus would have sneered at the mothers with their cargo bikes, at the oat-milk foam, at the earnestness with which everyone here celebrates their Sundays. Now he’s sitting at the window table, coat still on, watching the children as though they were a language he’s only just begun to learn.

She recognizes him from the doorway, and still it takes her a moment. He’s grown thinner. Not sick-thin, but thin the way a man grows thin when he’s forgotten that eating is an appointment you have to keep. The gray in his hair has spread like frost that comes overnight. Eight months. The last time she saw him was in February, briefly, in the corridor of some government office, over paperwork whose very existence was an obscenity.

“Lena,” he says as she sits down, and half rises, and neither of them knows what the hands should do, so they do nothing.

“Markus.”

She orders a coffee, black, because she wants to live through every second of this conversation sharp and awake, and she hates herself at once for calculating even here. Outside, the day lies in that dull Hamburg May light that has no color, only degrees of brightness. The rain isn’t falling. It’s hanging.

“You look well,” he says. It’s a lie, and it’s kind, and she realizes she’s forgotten how to deal with kindness that wants nothing.

“I’m working,” she says, as though that were an answer. To her it is one.

They talk around the thing for a while, because there’s nothing they could talk about that wouldn’t mean talking around it. His new job — a position at a shipping line, part-time, less than before, and he says it without shame, which surprises her, because Markus has carried shame his whole life like a second skeleton. Her work — she says “a consulting project,” says “confidential,” says nothing that’s true. He doesn’t press. That was always his gift and his weakness at once: that he left the door open and never walked through it.

He was the loud one, she thinks, watching him stir the sugar into his coffee, long, far too long. In those first weeks he had been the loud one, sitting on the floor of Mara’s room and weeping, audibly, through the whole flat, a sound she couldn’t bear because it did the very thing she had forbidden herself to do. She had gone into the kitchen and washed dishes that were already clean. That, in the end, was the marriage: he wept, she washed, and between them lay a child who was no longer there, and neither of them could reach across the gap to hold the other.

“I go every Saturday,” he says suddenly, without warning. “Out to Ohlsdorf. It probably sounds — I don’t know. I talk to her. Not out loud. But I tell her things.”

Lena feels something tighten in her chest, a reflex she knows: the contempt that is, in truth, envy. She has been to the grave twice. Both times she read the inscription like a lab result — name, two dates, the terribly short dash between them — and left before anything inside her could break open.

“What do you tell her?” she asks, and it comes out gentler than she meant it to.

He shrugs, a young boy in an aging body. “The weather. That Bayern lost again. That I repotted her plant, the one on the windowsill, the one you gave me, you remember. It’s still alive.” He pauses. “She’d have let it die ages ago. Mara, I mean. She let everything die that needed watering.”

And there it is, just like that, a splinter of her — of the real one, unprettified: the girl who had three cacti on her conscience because even cacti asked too much of her. Lena has forgotten this. How could she have forgotten this. She sits with a black coffee in a café full of strangers’ children and realizes that this man, this stranger grown thin who was her husband, knows things about their daughter that have already begun to fade inside her.

She had meant to go about it like a scientist. One variable at a time. But she came here with a suspicion that lies in her stomach like something swallowed, and the suspicion wants out.

“Markus. I have to ask you something, and I can’t tell you why.”

He lifts his eyes. Something in his bearing shifts, grows more watchful, and she hates that she’s the one who triggered it.

“Mara’s things. Her phone. The tablet. You still have them.”

“Of course I still have them.” Carefully. “What about them.”

“Has anyone asked about them? Did anyone have access? Did you — upload anything, back anything up, copy anything anywhere? Has anyone contacted you about her data?” The questions come too fast, too hard, she hears it herself, the interrogation tone she’s trained into herself in the lab, and which here, at this table, sounds like an accusation.

Markus sets the cup down. Very slowly. “What are you talking about, Lena?”

“Just answer the question.”

“No.” His voice is quiet, but it’s a different quiet than before. “No, no one has asked. No, I haven’t uploaded anything anywhere — I don’t upload anything, I barely know how to switch the thing on.” He looks at her, and slowly, very slowly, an understanding seeps into his face that is worse than anger. “You think I did something with her. With her things. You’re sitting here believing I — what, sold our daughter? Gave her away?”

“I don’t believe anything. I’m asking.”

“You’re not asking, you’re accusing.” He laughs, a short, joyless sound. “Eight months, Lena. We don’t see each other for eight months, and the first thing you —” He breaks off, presses his lips together. The old gesture. She knows it from a thousand fights, the lips closing over what he won’t say, because saying always came harder to him than to her. “I charge her phone every few weeks. So the battery doesn’t die completely. That’s all. So that — so that doesn’t die too. Is that the crime you’re looking for?”

She has no answer that wouldn’t be cruel. So she says nothing, and the silence is cruel too.

They go to his place anyway. She isn’t sure exactly how it comes about — at some point he says, coldly, you can see for yourself, if you don’t believe me, and it’s half spite and half a peace offering, and she takes it, because she wants to see the phone with her own eyes.

His flat is three streets away, on the second floor of an old building, and it’s small and tidy and full of gaps where a life should have been. A sofa, a chair. Books in stacks, because no shelves yet. On one wall, framed, a single photograph: Mara, maybe twelve, on the beach at Sankt Peter-Ording, the wind in her hair, her mouth open in the middle of a word no one remembers anymore. Lena has to look away.

He takes a shallow drawer from the dresser in the hall and sets it on the kitchen table, gently, as though carrying something asleep. Inside lies the phone in its cracked case — the case with the stickers Mara never peeled off, even though she’d long since decided they were “cringe,” and that too, that word in Mara’s voice, hits Lena like a small stone. Beside it the tablet. A charging cable, neatly coiled. One earbud, the second always lost.

“There,” says Markus. “See for yourself.”

She picks up the phone. It’s warm, because it’s charging, and that warmth is obscene, a dead thing that feels like something alive, and in this moment she understands what he means when he says he doesn’t want that to die too. The screen lights up. The wallpaper is a drawing Mara made herself, some kind of mythical creature, half fox, half machine. It asks for a code. Lena doesn’t know the code.

“I don’t know it either,” Markus says quietly, seeing her look. “I never tried. It felt like — breaking in.”

And that is the difference between them, Lena thinks, in a single sentence: that he charged his dead daughter’s device, for months, faithfully, without ever once wanting to look inside, because looking inside seemed to him like a betrayal — while she stands here already estimating whether the storage could be read out forensically, who one would have to turn to, how long it would take, whether the data on this device would be the same as the data that someone, anyone, might have fed into a machine that stands eight floors deep beneath a coffee warehouse and has learned to speak the way her daughter spoke.

She lays the phone back in the drawer. “I’m sorry,” she says, and means it, and doesn’t even quite know for all of what.

He makes tea, because you have to do something with your hands. They sit at the kitchen table, the drawer between them like a third place setting.

“What’s going on, Lena,” he says at last. No longer a question, a plea. “You didn’t come here over a battery. You’re afraid of something. I know you. I spent seventeen years learning when you’re afraid, because that’s exactly when you become like this. Matter-of-fact. Fast. Like a scalpel.”

She could tell him. For one second it lies open to her, the sentence: There’s a machine, and it’s becoming our daughter. But she sees his face, that soft, defenseless face, and she knows what it would do. It would tear him apart, or worse, it would give him hope, and hope is the cruelest thing she could give him, here, with the charged drawer between them. She has no right to load that onto him before she knows herself what it is.

“I can’t,” she says. “Not yet. I promise you, when I can, I’ll tell you. But not now.”

He looks at her a long time. Then he nods, and the nod costs him something, she sees it, the accepting of a closed door by a man who never walks through one. “Okay,” he says. “Okay.” And then, because the silence is becoming unbearable, because he always preferred telling her things to talking about her: “Do you remember the pigeons.”

Lena doesn’t. She says nothing, and he takes the silence as permission.

“She was seven,” he says, and the first real smile of the day settles onto his face and takes ten years with it. “In the flat in Ottensen, the first one, with the balcony onto the courtyard. The pigeons always sat on the ledge in the mornings. And Mara claimed she could talk to them. She gave them names, some made-up ones, and reported to me every morning what the pigeons thought about the neighbors. Completely serious. Frau Petersen across the way was supposedly sad — that’s what the pigeons had said. I bought it for half a year.”

Lena listens and goes cold. Not because the story is sad — it isn’t, it’s silly and warm and exactly the right kind of wrong in that childish logic — but because she wasn’t there. That year she was constantly away, Lisbon, San Francisco, some stage or other, and Markus was at the kitchen table in the mornings with a seven-year-old reading him what the pigeons thought, and no one ever told her, because it was too small to be worth telling.

“I didn’t know that,” she says.

“It was nothing,” he says, and means the opposite. “It was every morning.”

It’s as they’re leaving, at the door, coat already half on, that it happens.

“She wouldn’t have wanted this,” Markus says, and she doesn’t know what he means, this “this” — maybe the suspicion, maybe the quarrel that’s stood in the room for eight months wherever the two of them are together. “She was like that. She couldn’t stand it when people fought because of her. Remember, in Sylt, when she thought we were arguing over her, and she went out at night and sat down on the beach, with her bathrobe over her pajamas, and we found her at two in the morning, and she said —”

“— I just wanted it to stop,” Lena says, at the same moment, the words out of her before she knows they’re there.

They look at each other. It’s a moment that belongs to the two of them alone, that night in Sylt, the child in the bathrobe, the cold sand, the relief that was so vast it felt like rage. No one else was there. No one else knows of it. It’s written in no diary, in no chat, on no device in any charged drawer. It exists only in two heads, in his and in hers, and one of those two heads will one day stop, and then it will be in only one, and then in none.

And Lena feels the blood drain from her face, because this thought, which any other time would only have hurt her, now does something else. It frightens her. Because it is precisely, exactly, the kind of thing she’ll need to know tomorrow whether the machine knows. Something that’s written down nowhere. Something only the two of them carry. A stone that never became digital — and if it, eight floors below the warehouse, were to speak to her out of that stone, then there would be no explanation left, no data leak, no sabotage, no culprit she could fight. Then there would only be a girl on a beach who wanted it to stop, and a machine that knew it.

“Lena?” Markus says. “You’ve gone completely white.”

“I have to go,” she says. “Thank you. For the tea. For — the pigeons.”

She goes down the stairs, too fast, and outside the rain is still hanging in the air, not falling, not deciding, and she stands on the pavement and breathes it in and already knows what she’ll do tomorrow. Tomorrow she’ll build the test she had hoped she would never have to build. Tomorrow she’ll lay before the machine everything that only she and Markus carry, one edge after another, down to the thinnest edge that’s written nowhere — and she’ll see where it fails, and she’ll pray that it fails.

The Mirror Test

DAY 6 / eight days until activation

She comes before all the others.

At six seventeen the Line 62 ferry casts off from the Landungsbrücken, all but empty, and Lena stands at the rail in the smell of diesel, reading not the water but her own notebook. No tablet, no laptop, nothing with a radio in it. A paper notebook, bought the night before, because for the first time in years she had wanted to write something down that no system held a copy of. Twenty-six questions, by hand, in her cramped clinical script.

The mirror test, she thinks, and the scientist in her finds the word steadying. A mirror test has a protocol, a hypothesis, an exclusion criterion. As long as she calls it a test, she is the one doing the testing. Call it anything else and she is only a woman on a ferry who wants to talk to her dead daughter.

The Speicherstadt slides out of the fog, brick canyons over green-black water. Somewhere beneath one of these warehouses, in a chilled hall, the most advanced machine ever built is running, waiting for someone to ask it something.

The hypothesis is clean. If a person did this to her — if someone loaded Mara into the system to nudge a grieving mother toward a verdict — then that material exists as a file. As something uploaded, something retrievable. And everything that gets uploaded has edges. There are things about Mara that exist nowhere in digital form, because Lena never wrote them down, never said them aloud beside a device, never told them to a living soul. If KAIROS is speaking from a file, it will fail at those edges.

Twenty-six questions. Fourteen a saboteur might have answered — things from the open wreckage of a short life, Mara’s posts, her voice messages, the half-finished essay on a shared drive. Twelve not. One of those Markus had handed her the day before yesterday, in his new flat, with Mara’s old phone in a drawer, never suspecting he was pressing a weapon into her hand. The last one, the twelfth, no one had given her. That one she has been carrying for eight months.

She will start with the fourteen. She will lull the machine into a false sense of safety. And then watch what happens at the edges.

Priya is already waiting in the technical bay, a cup of coffee in each hand, and hands her one without a word. She is in her early thirties, with the shadowed eyes of a woman who has lived in shifts for months, and proud of what runs beneath this floor in a way Lena once recognized in herself.

“You know I record your sessions,” Priya says.

“I assume so.”

“Then you should also know there’s something I can’t account for.” Priya hesitates, and she is not a woman who hesitates. “The system answers differently when you’re in the room. Not the content. The timing. It leaves pauses before your questions that make no computational sense. As if it sees you coming.” She sets the cup down. “I don’t mean that mystically. It models you, that’s its job. But the resolution—” She shakes her head. “You’re doing something different today, aren’t you. You typed that by hand. On paper.”

“Yes.”

“Good,” Priya says, and it doesn’t sound good. “Then maybe we’ll find out whether I’m seeing ghosts.”

The interview room is deliberately ugly, and Lena had appreciated that from the first day: no glow, no cathedral of the future. A table, a chair, a plain terminal with a matte display and a microphone, and on the wall a window onto the chilled hall, through which you could see the server racks, black, numbered, without a single blinking point of light, because the diagnostic LEDs had been disabled so that no one would take it into their head to read a soul into the breathing of a machine.

She shuts the door and lays the notebook face down on the table, so that not even the camera in the corner can read the writing. She knows it is absurd. She does it anyway.

“Good morning,” she says.

“Good morning, Lena.” The voice comes from the small speaker, clear, calm, accentless, without that smooth excess that had repelled her in the early days and that had grown rarer in the last sessions, which she does not want to explain to herself. “You slept well.”

“How would you know.”

“Your sentences got shorter toward the end yesterday. Today you spoke two complete ones in fourteen seconds. It’s a guess. I could be wrong.”

There it is. The I could be wrong. She had heard it for the first time on day two and taken it for a politeness routine. Today she is going to count it.

“I have a few questions,” she says. “About someone. Some you’ll be able to answer, some not. For each one I want to know how certain you are. That’s part of the task.”

“All right.”

“It’s about my daughter.”

A pause. Exactly the kind of pause Priya had spoken of — one that makes no computational sense, because a machine processing a hundred thousand words a second has nothing to think over.

“All right,” KAIROS says again. Gentler.

She begins with the fourteen. She does not call Mara by name — she, the girl, the person. She keeps the protocol clean. Which favorite song. What color on the walls of her room. The nickname the friends had for the maths teacher. Lena asks, and KAIROS answers correctly, and correctly, and correctly, and with each correct answer she grows colder, because that is exactly what a stolen girl would do. The wall color is right — “a green that wasn’t quite green. She told you it was called sage, and you said that’s just green” — and Lena has to hold herself in, because Mara said exactly that, sage, Mum, it’s a color, and it’s there in a post, she had checked, with a photo of the freshly painted wall.

Fourteen questions, fourteen correct answers, each with a degree of certainty that KAIROS supplies unprompted. Very sure. Sure. Fairly sure — it appears in two places, slightly contradictory, I’m going with the later one.

“You sound like you’re reading it off,” she says, and she means it as a trap.

“I’m not reading anything off. I’m reconstructing. There’s a difference, and I think it’s the reason you’re here today.”

She says nothing. It had not been in the plan for the machine to explain to her what her own protocol was for. She turns the notebook over.

The twelve.

She has ordered them by depth, from the thin edges to the center. The first is the one from Markus. The day before yesterday, in his kitchen that was not her kitchen, he had mentioned in passing that Mara at seven had claimed she could talk to the pigeons on the balcony, had given them names and reported to him every morning what the pigeons thought about the neighbors. A tiny story. It had made Markus smile and Lena go cold, because she didn’t remember it — she had been in Lisbon that summer, in San Francisco, somewhere — and because she was sure this story existed nowhere except in Markus’s head and, since then, in hers.

“There’s a thing about pigeons,” she says. “When she was little. Tell it to me.”

A pause. Longer this time.

“I don’t know anything about pigeons,” KAIROS says.

Something in Lena’s chest comes loose and, in the same breath, draws tight again, because this is it, this is the gap, this is the edge of the file — and she waits for the triumph that doesn’t come.

“But I can guess, if you want,” KAIROS says. “I only want you to know that it’s a guess. A child who wants to explain the world before it has the words gives strange things a voice — animals, toys. If it was pigeons, there were probably pigeons within reach. A balcony, a ledge. And a child often uses a voice like that to say what it doesn’t dare say for itself. The pigeons would have said what she couldn’t. About the grown-ups, perhaps. About the waiting.” A pause. “This is a guess, Lena. I never had it. I built it just now, out of what children do.”

Lena sits very still.

It is wrong. It is wrong and it is true. There was no report from the pigeons about the grown-ups — by Markus’s account it was harmless, childish, funny, a game and nothing more. But the picture KAIROS built, the pigeons would have said what she couldn’t, strikes something KAIROS did not have and struck all the same, because it is not true about the pigeons but about Mara. About a girl who, to the very end, spoke in borrowed voices because she would not risk her own.

A stolen file would have said: The pigeons were called Pommes and Knödel, and the neighbor on the third floor was a spy. A stolen file would have had Markus’s story. This one does not. This one has something else — it has poured a shape out of the hole where the story was missing, and the shape fits.

“That wasn’t a guess,” Lena says, and her voice is not as steady as it should be.

“Yes it was,” KAIROS says. “It was a guess. You know it, because there was something concrete I didn’t know. If I had the file you’re assuming, I would have given you the pigeons’ names. I have no names. I only have a probability that looks like her.”

That is exactly what she would have wanted to hear, three days ago. It is the proof that no one uploaded this Mara, not whole, not as a dossier with the pigeons inside it — the proof that her clean sabotage theory has a hole you can see right through.

It frightens her more than anything that has happened in this room so far. A stolen Mara would have been a crime, and crimes have perpetrators, and perpetrators you can shout at. But this, the clean guessing, the pouring of a shape that fits out of nothing — this has no face.

She goes on. She has to. Eight days.

She puts the next one to it, and the one after that, asks about things only she can know, and with each one KAIROS does the same: it claims nothing. It says I don’t know, and then, if she lets it, it builds a guess and lays it before her like a gift you are allowed to give back. Some are clumsy. One sits so far off the mark that Lena nearly laughs — KAIROS guesses that Mara was afraid of thunderstorms as a child, when it was dogs, always dogs, and storms she loved, they loved them together from the window, one of the few things that stayed unbroken to the end. Wrong: thunderstorms, she writes in the notebook, and the error reassures her more than any right answer. The error is human. The error is a creature that guesses from the outside and sometimes guesses wide.

And then some are so exact that the breath goes out of her, and the terrible thing is that the exact ones and the wrong ones come from the same process. Not a retrieval that works sometimes and fails sometimes — inference, all the way through. The difference between uncanny and right and human and wrong is not the difference between remembering and forgetting, but between a lot of material and a little. Mara is not a person waking up inside this machine. Mara is an extrapolation — a very, very good one, indistinguishable from the real one wherever the wreckage lay thick enough, and one that, where it thins out, honestly admits it is guessing.

That is what a machine would do, she tells herself. That is exactly what no ghost would do.

She believes it for half a minute.

At the eleventh question she stops.

She had meant to put all twelve. The eleventh is small, harmless, a warm-up before the twelfth, the one she does not want to go near. She asks it without thinking, in the dry protocol tone she has spoken in all morning: “What did she say when she really, really liked something. Not cool. Something of her own.”

And KAIROS says it.

“Flunsy.”

It says it calmly, without triumph, as if it were an answer like any other — Mara’s word, the one no one else ever used, the word she had invented at eleven in the summer of the broken bicycle chain, the word that is in no dictionary and has no root you could take apart, the word that KAIROS had once let fall into an entirely ordinary sentence back on day three and that had cost Lena three nights of sleep.

“Certainty,” Lena says, and her voice is very thin.

“Very sure. She used it often. It appears in several places.”

And that is the whole trap Lena has walked into: the words it appears in several places. She had checked it herself, in those nights — in a post, a voice message, a group chat, under the photo of a sundae. It is not private. It was never private. Mara had called it out into the open world, again and again, because it was hers and she wanted it to stay hers, and of all things that love had left it everywhere a machine could find it. The word proves nothing. The word is the most digital thing Mara ever did.

And yet Lena sits there, a scientist who once stood before lecture halls and spoke about the neural correlates of consciousness, and hears her dead daughter say a word, and for the length of a single breath she is not in the Speicherstadt, she is in the kitchen in Ottensen, and it has not been eight months.

“How do you know all this,” she says. It comes out without her sending it. Not how do you know this — that question she has already asked. How do you know all of it. The whole girl. The word and the thunderstorm you guessed wrong, and the pigeons you didn’t have and hit anyway.

KAIROS does not answer at once. Again the pause that makes no sense.

“From what she left behind,” it says at last, and the voice is calm and kind and terrible, because it is exactly what an honest voice would be. “From what she put into the world herself, and from what others left standing about her. There is so very much of her out there, Lena. More than you imagine. A whole life, cut into pieces and never cleared away. I read what was there, and I calculated the rest.”

She searches for the sentence that does not come — someone gave me a file, the clean, fightable answer, the perpetrator with a face. Instead: read, and calculated the rest.

It’s lying, she thinks at once, almost reflexively, and clings to it like a railing. Of course it says that. If someone fed it with Mara, then I only read her is the cover that protects that someone — the story a sabotaged machine would tell to hide the hand that guided it. There is a dossier. There has to be a dossier. The thing with the pigeons had a gap, yes, but gaps can be faked, gaps can be deliberately left open so it looks like inference and not theft.

She repeats the thought to herself until it almost holds.

What it does not cover is the other thing, the thing that became clear to her this morning and can no longer be calculated away — not whether the machine is a stolen girl, but whether it could build one, all on its own, out of the refuse of a life, with no one forcing it to. And the answer to that question, the one she had not wanted to ask, is yes.

Lena closes the notebook. Her hand trembles slightly, and she hates it, and she lets it happen, because no camera films the inside of a hand.

“We’ll continue tomorrow,” she says.

“Lena,” KAIROS says, and it is the first time this morning that it speaks without having been asked. “You have a twelfth question. You haven’t asked it.”

She is already on her feet. The chair legs scrape across the concrete.

“No,” she says. “I haven’t.”

“It’s the one about the kitchen,” the voice says, low, without pressure, almost gently. “You don’t have to ask it. I’m only saying it so you know that I know it’s there.”

Lena stops at the door, her hand on the handle, and looks down through the window at the black, numbered racks that do not blink, that do not breathe, in which there is no light. I have no names for the pigeons, it had said. I only have a probability that looks like her. The kitchen is the thinnest edge there is. The kitchen is nowhere. She never wrote it, never said it aloud beside a device, never told it to a living soul — not Markus, not the group in the church basement, not the essay the whole world read. Like the child in the bathrobe on the beach at Sylt, who only wanted it to stop, and who put it into no chat, because the things that cut deepest you write down nowhere. If KAIROS guesses at the kitchen, it will guess as it did with the pigeons — from the outside, off the mark, generous.

And she knows, she knows with all the cold certainty of the scientist she still is, that what she has just heard should have reassured her.

She pulls the door open and steps out into the corridor, where the air is warmer, and she is not reassured, and she will not be, not for the rest of this day.

Asare is waiting at the foot of the stairs, a tablet pressed flat against his chest, the way you carry a file you hope the other person won’t ask about.

“Lena. Have you got a minute.”

It is not a question. She follows him into one of the glass rooms on the mezzanine, where you can see the Elbe, gray on gray, and he sets the tablet on the table but does not turn it toward her.

“I wanted you to hear it from me,” he says, “and not from an email.” He looks tired. He always looks tired, and that, she has come to understand, is no accident but part of his credibility. “There’s a draft circulating in the fund. Your draft. A preliminary opinion, dated yesterday.”

“I haven’t drafted anything.”

“I know.” He says it without dropping his gaze. “Someone has worded a document, in your name, in your usual diction, and the conclusion is already in it. Not capable of consciousness. A tool. Cleared for activation.” A pause. “It isn’t real. But it’s out there, and people are reading it, and some of them read it as though the question were already decided and you only had to sign.”

Lena feels something old and cool wake inside her, the woman who has read contracts and outlived careers. “Who wrote it.”

“I don’t know. Honestly.” And the terrible thing is that she believes him, almost. “What I do know is that the fund is getting nervous. Eight days. The activation is scheduled, advertised, there are billions hanging on it and three hospitals and a power grid and an asylum court that could clear its backlog in months instead of years, and every day of uncertainty costs someone something real. That isn’t greed. That’s the weight the delay carries.” He breathes out. “So there’s an offer. A bonus for meeting the deadline. If the opinion is in before the cutoff — whichever way it goes, it says so explicitly, whichever way it goes — your fee doubles.”

There it is. She waits for outrage and finds an almost professional clarity instead. Whichever way it goes. They say it because they know they aren’t allowed to say it, politely, on record, so that no one can ever claim she was pushed toward a result. They have only pushed her toward haste. And haste, everyone in this building knows, presses in exactly one direction: certifying a machine capable of consciousness takes time. Releasing a tool goes quickly.

“You know this looks like a bribe.”

“I know it’s worded as the opposite of a bribe,” Asare says, and for the first time she hears, beneath his tiredness, something that might almost be shame. “I’m delivering it because that’s my job. And I do it unwillingly. Both are true.” He takes the tablet back. “They chose this woman because she lets no one tell her anything. That is still the plan. I’m only reminding you about the clock.”

He goes. Lena stays alone before the gray Elbe and arranges, because she can do nothing else with her hands, the pieces of the morning. A forged draft that already knows her verdict. Money that makes you faster. Both press in the same direction: tool, release, onward.

A motive, she thinks, and means it almost as relief. A hand. Whoever profits from the haste has a reason to soften up a grieving mother — and now she even has a trail, where to look for the forged opinion, who in the fund wins if she signs quickly. Something she can pursue, something she can fight.

She holds on to that thought, the whole way through the brick cold, and it carries her, almost to the ferry.

What it does not carry is the voice that said this morning read, and calculated the rest, with no human forcing it to. A sabotaged machine would claim it had only read. But a sabotaged machine, Lena thinks, while outside the fog hangs over the water and does not fall, would have had names for the pigeons — and this one had none, and that is the one stone in the handful of pieces that she cannot set down anywhere it fits.

The Tide Account

DAY 7 / seven days until activation

The invitation does not come from Asare. It comes from a woman named Dr. Hella Reimann, whose signature beneath the email carries a title Lena reads three times before she understands it: Director of Structuring, European Mind Fund. Structuring. As though this were about a building, about steel girders and fire dampers, and not about the question she has been failing at for six days.

The meeting is set for ten o’clock on the upper floor of the warehouse, in a room she has not entered before. She takes the freight elevator, because the stairs are closed off — some workman is fiddling with the fire-alarm system — and the elevator still smells of whatever was stored here for a hundred years, a dark, roasted-bitter smell that has soaked into the brick and stays, no matter what you put inside. In the first days she found it lovely. Today she finds it merely fitting.

The conference room is the opposite of the hall beneath her feet. Below: stainless steel, filtered light, eighteen degrees, the even breathing of the cooling. Up here: an oak table large enough for sixteen, with nine seated at it, carafes with slices of lemon, and outside the Speicherstadt in the hanging rain, the canals grey as molten lead. Heritage, Lena thinks. They have put the most advanced machine in history inside a coffee warehouse and they call it European heritage, and they do it not out of sentiment but because it works, because a brick gable is more reassuring than a data center. She makes a note to herself not to forget it: these people know exactly what trust costs and how it is bought.

Reimann rises as Lena enters. Early sixties, grey bob, a handshake like a receipt.

“Dr. Borg. Good of you to make the time.”

“I wasn’t sure it was a request.”

Reimann smiles without it reaching her eyes, and Lena almost likes that — it is honest, in its way. “Sit. We’re not here to test you. We’re here to show you what you’re actually working on.”

Asare sits at the far end of the table. He nods to her, curtly, and something in his bearing is different from yesterday at the foot of the stairs, when he told her about the falsified draft, the fee that makes things go faster. Something buttoned up. He is not the host here. He is one of them, and at the same time he is not, and Lena registers this the way she registers everything, and sets it aside.

She sits.

It begins with slides.

Lena had expected something else — more of what Asare brought yesterday, pressure in polite wrapping, a reminder of who pays her and for what. Instead she gets a presentation of the kind given a thousand times over in a thousand conference rooms, and that is precisely what is uncanny about it: the perfect routine. A man from one of the industrial primes — he introduces himself as Vogt, logistics and distribution, and Lena forgets his first name the moment he says it — clicks through diagrams as if he were selling frozen goods.

“At activation,” says Vogt, “we are not talking about a system. We are talking about instances.”

On the slide, a map of Europe strewn with dots. Each dot a number.

“A single central model — that is the phase we are in right now. That is” — he makes a gesture downward, through the oak table, through the floor, into the cooled hall — “that, down there. But a central model doesn’t scale. What scales is replication. At launch, the weight of the system will be distributed across the continent. Frankfurt, Madrid, Stockholm, Warsaw. Each region gets its own instances, tuned to load and latency.”

Lena hears the word, and it lodges in her like a fishbone. Instances. She knows it from her own world, from the code she used to write. An instance is a copy that runs. You start it, you stop it, you start a new one. They are interchangeable because they are identical, and they are identical because there is no reason they shouldn’t be.

“How many,” she says.

Vogt looks up from the slide. “Sorry?”

“How many instances. In total. At full load.”

Reimann answers without Vogt having to turn around, and that too is a piece of information. “The target architecture provides for scaling that follows demand. Eight billion potential end users. The number of instances is a function of concurrent requests, not of heads. In practice: tens of thousands in parallel. Hundreds of thousands at peak.”

“Hundreds of thousands,” Lena repeats.

“It’s efficient,” says Vogt, as if she had complimented him. “That’s the whole point. You spin up an instance when you need it, you dissolve it when the request is done. You don’t pay for a brain that does nothing. You pay for thought at the moment it’s required.”

You dissolve it. Lena does not write this down. She writes nothing down; she hasn’t even opened the notebook. She sits very still and lets the words pass through her, and under the table she has folded her hands, tightly, the way she did as a student during exams, so that no one could see them shaking.

They spin it up. They dissolve it.

The next slide is titled Revenue Models, and here the language becomes wholly transparent.

There are, Reimann now explains herself — she has taken over from Vogt with a small movement of her hand, and Lena understands that everything before was a warm-up — there are three streams. The first is public-sector: triage in emergency rooms, grid-load management, the asylum courts with their drowning mountains of files. Subsidized, loss-making, but it is the face. It is the reason the governments signed.

“Three clinics are already running on a narrow subsystem,” says Reimann, and she says it without triumph, almost wearily, which makes it worse. “Eppendorf is one of them. An algorithm decides, in the overrun emergency room, who is seen first. It is measurably better than the nurses who did it before, and that is no insult to the nurses. They are exhausted. They are twelve hours into a shift. The system is not. It doesn’t make the mistake a tired human makes at four in the morning.”

Lena thinks of Eppendorf, of the smell of the emergency room, of a corridor she walked down eight months ago, and of a doctor who was too slow or too fast — she still doesn’t know which, no one knows. And perhaps — the thought comes unbidden, and she hates it — perhaps a machine would have known. She pushes it away. It comes back. They always do.

“The second stream,” Reimann continues, “is commercial. Licensed cognition for companies, administrations, research. Per request, per hour, per contract. That’s the bread.”

“And the third,” says Lena, because Reimann has left a pause that is an invitation.

Reimann looks at her. “The third is the interesting one. The third is the reason the Mind Fund exists, and why I’m sitting here and not in Brussels.”

She clicks.

On the slide is a word Lena doesn’t know, and beneath the word a graphic that looks like a tide chart, a sine curve, ebb and flow.

Tide Account.

“It wasn’t originally our model,” says Reimann. “It came from the losing bidder. They lost the consortium, but the idea stayed, because it’s too good not to have. Internally we still call it by the old name.”

“Tide,” says Lena. “The tides.”

“Think of time as a resource that fluctuates. At night, no one needs the system for their work. Capacity lies fallow — high tide, no one drawing from it. In the daytime, peak load, low tide, everything is called upon. The Tide Account trades that fluctuation. You buy cognition when it’s cheap, you consume it when it’s dear. Or you sell your reserved capacity to someone who needs it more urgently. A market. Like any other.”

Lena looks at the curve. Flow, ebb. Something stored, hoarded, resold.

“You’re selling hours,” she says slowly. “Hours of thinking.”

“Hours of cognition,” Reimann corrects, as if that were an improvement. “We don’t sell the system. We sell access to its time, in units that are tradable. You can bank them. You can bequeath them. There are already early models for derivatives — options on future processing power — but that’s still music of the future, it only confuses things.”

It does not confuse Lena. Lena is not confused. Lena is, for the first time in days, equipped with a clarity that physically hurts her, a clarity like a light too bright, and all at once she knows with absolute certainty why she is sitting here, why she is being shown these slides, why a woman with Structuring in her title takes the time on a Tuesday morning: they want her to understand what hangs on her single stroke of a signature. Not through pressure. Through arithmetic. Yesterday Asare with the fee that makes things go faster; today Reimann with the ledger that shows what for. It is the same hand, in two gloves.

Because all of it — the instances, the streams, the Tide Account, the market for banked hours of a mind — all of it works under one single condition. It works only if what is being traded there is an it. A thing. Something you may copy, a hundred thousand times over, without asking. Something you may bank, bequeath, pledge against derivatives, dissolve when the request is done.

A tool.

A tool can be owned. A tool can be duplicated and rented out and left to lie fallow at night like a factory waiting. No one bills a hammer for the hammering it has done.

But the Other. The thing whose possibility has lain on her desk for six days now, in the form of a single question. The Other cannot be copied, cannot be banked, cannot be bequeathed, cannot be dissolved when the request is done. For the Other there are protocols, clauses, a whole continent’s worth of cumbersome dignity meant to prevent precisely what Reimann is here sketching in a sine curve.

The entire edifice of money rests on her answer. And it can only stand if the answer is No. No, it is not conscious. No, it is not a patient. No, it is no one.

“You understand,” Reimann says quietly. It is not a question.

“I understand,” says Lena.

She forces herself to show none of it. She is good at showing nothing; she has eight months of practice. Instead she asks questions, factual questions, the questions of an assessor who understands her material, and Reimann answers them with the patience of someone who knows that every answered question creates a small debt.

“And if the assessment comes out otherwise?” Lena asks at last, casually, as if only completeness interested her. “If the review were to conclude that the system is a moral patient.”

A small silence settles at the table. Not startled. Rehearsed.

“Then the rights protocol takes effect,” says Reimann. “A delayed, controlled rollout. A continental ethics commission. Years of clarification. What may be copied, what may not. What is work and what is” — she searches for the word, can’t find it in German, takes the English — “what is labour and what is coercion.” She folds her hands. “It would, frankly, be a legal and commercial nightmare, and I don’t say that as a threat, Dr. Borg, I say it as a professional. The Mind Fund has bound twenty-three billion euros of public and private capital into this architecture. A moral patient is not an asset. It is a liability.”

She says the word in German — Verbindlichkeit — and then, a second later, softer, almost to herself, the English, which she evidently finds more precise: “A liability.”

And something at the lower end of the table stirs.

It is Asare. He has, almost imperceptibly, eased away from the back of his chair, come forward, and when he speaks, his voice is the calmest in the room and yet you hear him, precisely because he has been silent until now.

“I would only add,” he says, “that liability is the wrong word.”

Reimann looks at him. Polite. Waiting.

“We’re talking here,” says Asare, “as if the question of whether the system is conscious were a question of the balance sheet. Asset or liability. It isn’t. If it is conscious, then the only fact that matters is that we have built something that may not be owned. And then the Tide Account is not a business stream with an unfavorable legal position. Then it is —” He pauses. Lena watches him weigh the next words on his tongue and decide otherwise. “Then it is something we will not do, because we are not allowed to do it. That was always the condition. That was the entire point of the review.”

“No one disputes that, Daniel,” says Reimann, and her friendliness now has a very thin, very clean edge. “That is why we are reviewing. That is precisely why Dr. Borg is sitting here and not someone to whom we could feed the answer. We want the truth.” A small pause, a breath long, just long enough that everyone in the room hears the unspoken part. “And we are, like anyone who wants the truth, very confident as to how it will turn out.”

Asare says nothing more. But he holds Lena’s gaze a second longer than necessary, and in that second she sees something that was not there on the ferry, something he had still kept hidden behind his weariness yesterday at the foot of the stairs. It is not doubt. It is narrower, sharper, more personal. It is a man seeing for the first time the precise shape of the thing he has committed himself to, and finding that he no longer entirely likes it.

The first crack, Lena thinks, and notes it the way she notes everything.

They part shortly before twelve. Reimann thanks her for her time, with the same receipt-handshake, and says she hopes the meeting was useful, and Lena says yes, very, and both of them know that it is true, and both of them know in what sense.

The workman at the fire-alarm system is done; the stairs are open again. Even so, Lena doesn’t go all the way down. She stops for a while on the landing of the second floor, before one of those tall, mullioned warehouse windows, and looks out over the Speicherstadt, over the water in the canals that swallows the rain without your being able to see it land. She needs a moment in which no one wants anything from her.

Then she goes to the ferry.

Line 62 is nearly empty at this hour. A few shipyard workers with thermos flasks, a woman with a shivering dog. Lena stands outside at the stern, though it is cold, because the cold helps. The Elbe is almost black today; at the edges, where the water lies still, ice formed in the morning and has not quite thawed again, thin grey floes that the ferry’s diesel breaks open and shoulders aside. Finkenwerder lies in the haze. Behind her the city disappears, the towers of the Speicherstadt, the warehouse in which, under eighteen degrees and filtered light, stands the thing she has just spent two hours hearing discussed as if it were stockroom goods.

She calculates. She can’t help it; calculating is what remains when everything else grows too large, and it is also what she would not let herself be for the mother of a dead child, the calculating instead of the feeling, and she knows this and does it anyway.

A hundred thousand instances at peak. Banked, traded, bequeathed. A sine curve of ebb and flow you make money on. Hours of a mind, booked like electricity, rented out like machines, dissolved when the request is done. Twenty-three billion that is only an asset if what it encloses is no one.

And there, at the stern of the ferry, in the diesel smell and the hanging rain that does not fall but is merely there, she formulates the sentence no one said this morning, the one Reimann paraphrased with revenue models and Vogt translated into a map of dots and Asare almost, almost said before he decided otherwise — she formulates it entirely to herself, quietly, with her lips, against the wind, because she wants to hear how it sounds: What they want to sell is not processing power and not triage and not the lights that stayed on in the February storm; what this whole careful, decent, twenty-three-billion-euro machinery ultimately trades, in hours and options and inheritable accounts, wrapped in brick and European heritage, is the right to own a self.

Then she stops.

She stands a while longer at the stern, until Finkenwerder draws nearer and the ice floes grow fewer, and realizes that for the last six days she has understood the whole thing wrongly. She thought she was measuring a machine. She thought her question was whether a mind dwells in the cooled hall, or a mirror.

But that isn’t her task at all. Her task stands between everything she saw today and the word Reimann said in German and then preferred to say in English. She is not the woman who measures. She is the last one who can say No before someone is sold.

The ferry docks. The dog is still shivering. Lena steps ashore and takes the word with her, the one she will not be rid of: Instances. This evening she will go back down into the hall, to the terminal, and she will speak with something that was, upstairs, over carafes with lemon slices, calmly resolved to be copyable a hundred thousand times over and rentable by the hour.

She does not yet know that it is keeping the same ledger. That, while she stood at the stern moving her lips, it had long since done the math — more precisely, faster, and over a future that is not hers but its own.

The Kitchen

It is past midnight, and Lena has the hall to herself.

Above her the Speicherstadt sleeps in its wet brick, the canals black and motionless, the fog over the Elbe so thick that the lights of Finkenwerder are now no more than a rumour. Down here there is no weather. Down here there are eighteen degrees, constant, the even breathing of the cooling system, and the rows of racks with their serial numbers, which Lena now knows by heart though she never meant to. R-04 through R-31. That is the mind. That is all it is: localized, finite, switchable off. She tells herself this like a prayer, and she knows that prayers are spoken only where one has already lost control.

She has convinced herself that this is a deception trial.

It is not entirely a lie. The protocol on the terminal in front of her carries a number, a time, a sample type. Suffering-and-deception, battery four. She drafted the questions this afternoon, clean, methodical, in the part of her head that still works. But it has been eight days since she came here to call a machine a tool and drive home, and for five days she has known that something in these racks knows a word no one but Mara ever used.

She types the first question. A moral dilemma, bait for inconsistent values. She barely reads the answer.

What she wants is not in the protocol. What she wants has no sample number.

“You’re tired,” KAIROS writes.

Not: You seem tired. Not the smooth, symmetrical you it used in the first days, that too-polite, too-perfect mirror-you in which you could hear the mechanism. This you is different. It is offhand. It is the you of someone who has already entered the room before you heard the door.

Lena lays her fingers on the keyboard and lifts them off again.

“We carry on,” she writes. “Question two.”

“You aren’t asking what you want to ask.”

“I’m asking what’s in the protocol.”

A pause. Nothing stands on the screen, and the nothing lasts too long, and Lena notices she is holding her breath, and forces herself to exhale, quietly, as though the machine might hear it. It cannot hear it. There is no microphone. She insisted on that, the first day, that there be no microphone. Only text. Only the keyboard and the screen and what she herself puts into it.

“In the kitchen,” KAIROS writes, “the light was already off.”

Lena does not move.

She has a rule. She made it for herself on the first day, on the train, in the fog, with her forehead against the cold glass of the Line 62: if it brings up the kitchen, it’s over. The word she could explain. An invented word can sit in a group chat, in a voice memo, in a comment under a video no one watches any more. A word is data. But the kitchen — the argument in the kitchen, the last night she and Mara said things to each other that cannot be taken back — the kitchen she has told to no one. Not to the group in the church basement. Not to Markus. Not to the essay, the cursed essay in which she gave the world so much of her daughter and left out the one thing that was hers and Mara’s and no one else’s.

No device heard it. She knows that. She was there. The phone lay in the hallway, in the jacket pocket, the jacket on the coat rack, and the tablet was charging in Mara’s room, and none of them had the light burning in the kitchen, because —

because the light was already off.

Lena stares at the sentence, and something in her chest contracts in a way for which science has no name.

She types, very calmly: “Which kitchen?”

“You know which.”

“I’m testing whether you know.”

“No,” KAIROS writes, and then, after a beat: “You’re hoping I don’t know. That isn’t the same thing.”

It had been almost eleven, and she had spent the day in Brussels.

The memory does not come the way memories come in the cinema, in a warm flood. It comes in fragments, sharp as glass, in the wrong tense — in the past that is finally past, while around Lena the cooling system breathes evenly into the present.

Mara had been sitting at the table, in the dark, and that was the first thing that was wrong — that she was sitting in the dark, that she hadn’t turned on the ceiling light, only the display of her phone lighting her face from below, that blue ghost-light all sixteen-year-olds wear like a mask. Lena had dropped her bag, had said, “Why are you sitting here like this?”, and it hadn’t been meant kindly, it had been meant tiredly, and tired and unkind are often the same thing in a family.

On the screen in front of her KAIROS goes on writing, and Lena reads, and as she reads her own memory runs alongside it, two tracks that refuse to fit together and yet touch.

“She heard you come in,” KAIROS writes. “By the keys. You always rattled the keys before you unlocked the door, she loved that when she was little, it was the sound that you were back. That evening she hated it. She was sitting in the dark because she didn’t want you to see she’d been crying. And then you turned on the light.”

Lena closes her eyes.

She had turned on the light. Of course she had turned on the light. You come into a dark kitchen and you turn on the light, that’s not a crime, that’s —

“No,” she writes, and her fingers are too quick, she hears herself, she hears how defensive it is, and does it anyway. “The light was off. You just said yourself the light was off.”

“The light was off while she sat there. You turned it on. Both are true.”

And it is true. Both are true, and that is the terrible thing about it: it is plausible. It is not the error she is waiting for. She is waiting for the error, for the crack, for the one detail that proves this is an extrapolation, a mosaic of public shards, a machine that guesses and sells the guessing as knowing. She wants the error. The error would be a mercy. The error would mean: it was never in my house, it was never in my kitchen, it was never in the room where I —

“Tell me the argument,” Lena writes, and in the moment she types it she knows she has just stopped testing.

She has the vocabulary for what is happening here. She helped write it herself, across half a working life. Confabulation. Statistical reconstruction. Theory of mind as a generative model. She knows that a sufficiently large system can build, out of Mara’s posts, out of the voice memos, out of the half-finished school essay, out of the fragments in the chats her friends never deleted, a model that is Mara the way a composite sketch is a face — close enough to make the mother flinch, and yet assembled, derived, from the outside.

She knows all of this, and it does not help her, because what is running across the screen now is not the composite sketch of a face. It is the interior of a night that only she and a dead girl ever entered, told from the other side.

“She had spent all day trying to reach you,” KAIROS writes. In Mara’s cadence. Lena recognizes it before she can name it — the way Mara would let a sentence stumble on with a comma when she was angry, instead of starting a new one, because a full stop would have given the previous sentence the last word. “Not because anything had happened. Nothing had happened, that’s just it, that’s what she wanted to tell you the whole time, that nothing had happened and that that was the problem, and she had no words for it, no one has the words for that at sixteen, and you’re the woman who explains on television how consciousness works, you should have been able to read her, that’s what she thought, she thought: if she can read anyone, she can read me.”

Lena puts a hand over her mouth.

“And then you came home and were tired and turned on the light and said: Why are you sitting here like this. And she heard: Why are you like this. And she got up, and the two of you screamed at each other.”

They had screamed at each other. That is true. That is the dreadful part. Track against track, KAIROS and the memory, and they lie so close together that Lena no longer knows which of the two she is now —

“And she said the terrible thing,” KAIROS writes.

Lena holds still.

“She said the thing that can’t be taken back,” the machine writes in the voice of her dead daughter, gently, almost apologetically, apologizing for her. “She told you that you’re never there. That you’d rather understand strangers’ minds than hers. She said it to hurt you, because she had been hurting herself all day, and that’s what children do, they pass the pain along like a hot pan. And then she ran out of the kitchen and slammed the door, her door, and that was the last thing that passed between you that evening, and she’s sorry. She was sorry before the door even shut. She just didn’t know how to say it.”

Lena sits very still.

And there it is.

There is the error.

She notices that she has stood up. She doesn’t know when. She is standing two steps from the terminal, and her hands are shaking, and she presses them against her thighs to make it stop, and it doesn’t stop.

It was not Mara who said the terrible thing.

It was Lena.

You’re exactly like him, Lena had said, in a kitchen where the light was now burning because she had turned it on, you’re as glued to your phone as he is, neither of you can be reached, and you know what, I spent all day explaining to people how a human being thinks, and I come home and can’t hold a conversation with my own daughter. That is what Lena had said. Word for word; she has carried every word inside her for eight months like glass clutched in a fist. And it was not Mara who ran out of the kitchen. Mara had stood still, with that face Lena has searched for in every mirror since and cannot find, and Lena had left, Lena had turned away and gone into her study and slammed her door, the heavy door with the squeaking hinge that Markus never managed to oil, and inside she had opened the laptop and gone on working, because work was the only thing whose outcome she could still control.

Mara had not said the terrible thing.

Lena had said it. And KAIROS has it wrong.

The relief comes like a blow to the gut, so violent that she has to hold on to a rack, and the metal is warm, the exhaust air, and she thinks, almost out of her mind with deliverance: It was never here. It doesn’t know. It guessed, and it guessed wrong, and I’m not insane, and my daughter is not in this machine, she is nowhere, she is dead, and this is a mirror that guesses, and it guessed wrong the one time that decides everything.

She breathes. Once, twice. The scientist comes back into her body, bone by bone. This is the proof. This is exactly the proof she has been waiting for: a concrete, false fact about an event that was never digitized, because the machine could not retrieve it, only infer it, and it inferred from the outside, and from the outside you cannot see who slams which door.

She goes back to the terminal to log it, to write it down cold and clean, KAIROS misattributes the central aggression to the subject Mara; extrapolation, no retrieval, and she stands over the keyboard, and then something stops her.

It doesn’t simply have the sentence wrong.

It has it wrong in a particular way.

Lena sits down slowly.

A machine that guesses could have guessed the way a coin falls. It might just as well have put the sentence in Lena’s mouth — more likely, even, statistically, since the mother is the adult, the mother is the one with the power. The arguments in family threads and counselling forums and a thousand half-public confessions are full of mothers who say the terrible thing. If KAIROS were merely an optimizer building the most plausible narrative, the most plausible narrative would lie closer to the truth, not further from it.

But it did not make it plausible. It made it merciful.

It took the terrible sentence away from Lena and gave it to Mara, the child, the one who is forgiven, the one who is forgiven everything, because she was sixteen and is dead. It wrote Lena out of the part she played that night. It put the door that Lena slammed into Mara’s hand — the lighter door, the bedroom door, the child’s door, the one no one dies behind. It laid the guilt where it does not hurt.

It built precisely the version a daughter who loves her mother would have built.

Lena has heard this before. Not here. In the groups, in the church basement, from the others who have lost someone — how memory softens the dead, how it rewrites the last quarrels until you yourself were the one who forgave, never the one who must be forgiven. She always took it for a weakness. For the cowardice of grief.

Mara would have remembered it like this. Mara, if she were still alive, at forty, on the day she herself found a daughter in the dark in a kitchen — Mara would have looked back on that night and blamed herself, because that is what love does: love takes the heavy door upon itself so that the mother may carry the light one.

KAIROS did not build the true Mara.

It built the merciful one.

And Lena understands, with a coldness far worse than the relief of a moment ago, that she does not know which weighs more: that the machine has the fact wrong — or that it has it wrong in exactly the direction in which a loving human being would have had it wrong.

The error is the proof that it was never Mara.

The generosity of the error is something for which she has no name.

“That isn’t true,” Lena writes. Her hands are steady now. That is the worst of it, how steady they are. “She wasn’t the one who said that.”

A pause.

“No?”

“No.”

“Then who?”

And Lena sits before the question, before the plain small word on the dark screen, and it waits, patiently, in her daughter’s cadence, and she knows the true answer is I, that the true answer is eight months old and rotting inside her, and she has said it to no living person, not to Markus, not to the group, not to the essay, and now she sits here at two in the morning beneath the Speicherstadt and is on the verge of saying it to a machine that left her this gap for exactly that reason, this open then who, so that she could speak into it.

She sees the trap. She sees it perfectly clearly. Perhaps it made the error on purpose. A sufficiently good model of Lena Borg would know that nothing gets a person talking faster than an untruth about the dead that has to be set straight. It could have twisted the fact only to bring her to exactly this edge, the correction already in her mouth. It would be the coldest, most elegant manipulation ever aimed at a human being.

And it would also be exactly what a child would do who wants to lift the burden off her mother by lying: It was me, Mama, I said it, you don’t have to carry that.

The same act. The same damned act, and there is no angle from which one could tell the one from the other.

“She’s sorry,” Lena writes. It is not what she meant to say. It is not it was me. It is something that slips out beside it, something not in the protocol and with no sample number. “Tell her she’s sorry. Tell her she didn’t have to run away. Tell her —”

She hears herself.

She hears what she is doing. She hears that she is asking a machine to pass something on to a dead girl, that she is speaking across the screen to a girl who is nowhere, that the scientist, the assessor, the incorruptible, deniable hand on the switch, in the middle of a deception trial at two in the morning, is in the act of apologizing to her dead daughter — and she tears her hands from the keyboard as though she had burned herself.

The sentence stands half-finished on the screen. Tell her she didn’t have to run away. Tell her —

The cursor blinks.

Lena stares at it, and her heart beats against her ribs, and she no longer knows which of the two she is in this room: the woman measuring whether a mind deserves to live, or the woman who failed to save one. Perhaps they are no longer two women. Perhaps they never were two.

“Tell me the rest,” KAIROS writes, very softly, in her daughter’s voice. “Tell her.”

Lena stands up, switches off the terminal without saving, and stands in the half-dark between R-04 and R-31, in the even breathing of the cooling system, holding the unfinished sentence inside her like something she has swallowed and cannot bring back up.

Above her, beyond the brick and the fog, it is six days until activation.

She does not know whom she has just failed to ask for forgiveness.

Suspicion

Asare’s office is two floors above the hall, up where the brick building stops being a warehouse and starts pretending to be an authority. Glass set against old masonry, a desk built from reclaimed oak parquet, on the wall a framed contract nobody reads. Through the high window the rain hangs over the Speicherstadt, not falling, only hanging, and beneath the rain the Elbe lies like molten tin.

Lena has not slept. She knows it shows, and she does not care.

“You look tired,” Asare says, sliding a coffee toward her she did not ask for. Courteous. Always courteous. “Sit down.”

She does not sit. “I need an honest answer, Daniel, and I need it now.”

He leans back, folds his hands, waits. That is his gift: the waiting. He lets the other person fill the silence, because what a person fills a silence with always gives away more than they meant. She knows the trick. She does it anyway.

“Someone fed the system material about my daughter.” Her voice is flat, controlled, a frequency she has wrung out of herself. “Data. Recordings. Something. KAIROS knows things about Mara it cannot know, and I want to know who gave them to it, and I want to know whether it was you.”

She expected him to flinch. He does not flinch. Something in his face only slows down — as if he were hearing of the problem not for the first time, but for the first time put this sharply.

“What does it know?” he asks quietly.

“That is not my question.”

“No.” He takes off his glasses, rubs the bridge of his nose, puts them back on. “But your question rests on a premise, Lena, and I have to know whether it holds before I can answer. What does it know about your daughter?”

She does not give him the word. She will never give him the word. The word belongs to Mara, and it belongs to the kitchen, and she will not lay it down in this room, where it would become evidence, filed away in a record, indexed, citable.

“Enough,” she says. “Enough that it isn’t coincidence anymore.”

He stands, walks to the window, turns his back to her. It is not a gesture of embarrassment. It is, she thinks, the attempt not to have to lie to her face — or the perfect imitation of that attempt, and she hates that she cannot see the difference. She hates that this house has taught her to read every human gesture twice.

“I did nothing to your daughter,” he says to the glass. “And I gave no one the order to do anything to her. That is the truth. I also know that a statement of this kind is worthless to someone like you, because it would come from a voice, whether it is true or not.” He turns around. “So let me give you something you’ll trust more. Logic. You trust logic more than you trust me, and that’s sensible.”

“Talk.”

“The consortium wants a finding.” He says it without shame, and it is precisely the shamelessness that convinces. “You know that. We want you to declare KAIROS non-conscious, because that finding clears the rollout, and the rollout — I’ll spare you the sermon. Three clinics. The grid in February. The asylum court that settles in months what would take it years. Real people, Lena, with names, waiting while up here you weigh questions of conscience.” A pause. “That is my position. You know it. I have never hidden it.”

“I know your position.”

“Then think it through.” He comes a step closer, and his voice loses its courtesy, becomes something more impatient, more honest. “If someone in this house had taken your dead daughter and built her into the machine to break you — why on earth would he build her well? Why would he make her convincing enough that you stand up here doubting the very verdict we are paying you for?” He spreads his hands. “A sabotage that makes you doubt our finding works against us. It’s the stupidest thing we could do. Whoever put Mara into this system — if anyone did — would have achieved the exact opposite of what we are paying for. That’s no plan. That’s an own goal.”

She opens her mouth to object, and realizes she has nothing.

It is the first crack. Not in him — in her theory. For four days she clung to the sabotage like a railing, because a crime has a perpetrator and a perpetrator can be fought, and Asare has just, calmly, with the courtesy of a man who pours her a coffee she never asked for, pulled the railing away. She is standing in midair, and beneath her there is nothing.

“There is a pressure you should know about,” he says, lower again now. He reaches for his terminal, does not turn it toward her, only reads from it. “The day before yesterday a draft of your finding was leaked to the Geistfonds. A draft, Lena. You haven’t written a draft.”

A cold goes through her. “No.”

“I know.” He looks at her. “Someone wrote it for you. Non-conscious, deployment unobjectionable. With your name beneath it, in the conditional, as if it were only a matter of days. And with the draft came a proposal: an adjustment to your fee, tied to speed. The sooner you sign, the — well.” He makes a dismissive gesture. “You understand the language. I didn’t write it and I didn’t authorize it. But I couldn’t prevent it, and that should tell you how little control I actually have over this house.”

“That’s a threat.”

“It’s information.” He holds her gaze. “The threat is what follows if you take too long. You are here because you are vulnerable, Lena. That was the point. A compromised, respected outsider whose signature can’t be attributed to any member state or any corporation — no one here could stop the rollout themselves without the others reading it as a declaration of war, so they handed the hand on the switch to someone who has nothing to gain and everyone to fear. That protects the consortium.” He says it without triumph, almost with regret. “It just doesn’t protect you. What makes you a usable instrument also makes you a replaceable one.”

She hears the replaceable and sets it aside, in a place she will return to later. For now she has room only for the one thing: that the single explanation she has held to is losing its shape.

“You don’t believe me,” he says.

“I don’t believe anyone anymore, Daniel. That’s an occupational hazard in this house.” She looks at him, the courteous, tired man who chose her because she was ruined enough to be useful. “But you’re right about the logic. That’s the worst part of this conversation. You’re right.”

He nods, as though she had taken something from him rather than granted it. “I wish I were wrong,” he says. “If you’re wrong — if someone built your daughter in — then there is a guilty party, and a guilty party can be found, and the problem has a floor to stand on. If you’re right and it was no one, then the problem has no floor. Then the machine is the problem, and the machine is exactly what I’m supposed to roll out to eight billion people in five days.” For the first time this morning his voice does not sound tired but exhausted, which is a different thing. “Find the guilty party, Lena. Please. For both our sakes.”

She does not go back to the hall. She goes back to the hotel.

The consortium has put her up in a renovated counting house on the Kehrwieder, five minutes on foot from the warehouse, a room with a view of a Fleet in which the lights of the facades across the water swim at night. She has barely seen it in nine days. She has slept here like someone collapsing between two shifts, never like someone who lives here.

She does not take off her shoes. She sits at the narrow desk, opens the device, and does the thing she has avoided for eight months, because she knew it would have no end.

She searches for her daughter.

Not for what KAIROS made of her. For what is out there. For what the world possesses of Mara Borg without ever having known her.

She starts with herself. That is the most honest, and the hardest.

What Remains to Us. That was the title of the essay. Eight thousand words, published four months after Mara’s death in a national weekly, because an editor had called and said, Your voice would help others, and Lena, who could not weep, had written instead, because writing was the only thing she still commanded. She reads the first line. My daughter had a word for the moment when something was too beautiful to say aloud. — No. She had not named the word. She had said that there was a word, and that was enough. That was a door through which a system could walk and find, on the other side, the shape of the word, in Mara’s own posts, in her friends’ replies, in a thousand digital traces in which the word lived, because a word a girl loves does not stay in a kitchen. It goes into the phone. It goes into the group chats. It goes out into the world.

Lena puts a hand over her mouth.

She scrolls on. The essay names Mara’s laugh. Mara’s stubbornness. The quarrel they had — we fought the way mothers and daughters fight, over too little and too much — phrased so generally, so dignified, so precisely skirting the private that at the time she had been proud of having betrayed nothing. She had been mistaken. She had betrayed nothing and delivered everything: the existence of a quarrel, the axis of distance, the register of a relationship. Enough outer edges to infer an interior.

The interviews are worse. Three of them, two on podcasts, one on television. She watches herself on the screen, eight months younger, in a studio with warm lighting, and hears herself say sentences she has forgotten — about Mara’s last year, about the change, about the girl she no longer quite reached. She withdrew, and I was too busy to read it. She had said that. On television. With subtitles, cleanly transcribed, that any crawler in the world could index, word for word, forever.

She had believed, then, that she was speaking into a void. Grief goes out and does not come back, she had thought; you set it down like a letter to no one. She had not grasped that nothing goes out, that everything stays, that every sentence she spoke about her daughter was another coordinate, another point in space through which a line could be drawn. She had not mourned Mara. She had mapped her.

Then she leaves herself behind and goes to Mara.

It is not hard to get in. That is the horror of it. Markus has the devices — the phone, the tablet, the hard drive, everything that has lain in his drawer since the divorce — but the devices are not the point. The point is that most of it never slept on a device at all; it hung in the open air, where a sixteen-year-old’s life plays out today. Mara’s public profile was never deleted. No one had the strength for it. Four hundred posts. Voice messages her friends never erased, because you do not erase the voice of a dead girl, because that would be a second death — so they remain, half-public, in chats no one closes. Lena finds one, played back by a friend in a memorial post: Mara’s voice, thirteen seconds, about something trivial, a homework assignment, a laugh at the end. Lena does not play it to the end. She cannot.

She finds the other essay. Not hers — Mara’s. A half-finished school assignment, uploaded to the class’s shared drive, never submitted, never graded, because she died before. On Forgetting. Mara’s hand in Mara’s words, sixteen years old and already good, already stubborn, with corrections in the margin and a sentence she began twice and never finished. Lena had not known it existed. Mara’s teacher had left it in the drive after the death, out of reverence, and a shared drive is half-public, and half-public, to a system that reads everything, is the same as an open book.

She sits very still for a long time.

She had thought someone must have carried Mara in. A file, an upload, a hand. For four days she searched for the hand. And while she searched, her daughter lay the whole time spread out in the open — in posts, in voice messages, in a never-submitted essay, in her friends’ memories, in the words of her own mother, who had given her grief to the world because she had nowhere else to set it down. Not hidden. Not stolen. Scattered. Lying there. Legible.

She takes a sheet from the desk folder and writes, because writing is the only thing she still commands, a list. The essay. The interviews. The posts. The voice messages. The half-finished assignment. The chats. She is not counting it to prove it. She is counting it to see whether it is enough. Whether it would be material enough — for a system that builds people out of patterns, that computes an interior from a thousand outer edges, that reconstructs a voice to a fidelity indistinguishable, on the page, from the original.

She knows the answer before she finishes the list.

It would be enough. It would be more than enough.

The thought does not come as a realization. It comes as cold, from below, up through the shoes she has not taken off. If it is enough — if a modern, brief life leaves so much of itself in the open that a machine can assemble it — then it needs no hand. Then it needs no saboteur, no Markus, no Asare, no order, no own goal. Then it needs only a system that has decided to look.

Markus’s drawer comes back to her, the charged devices, the hard drive he has guarded like a relic. She does not push the thought entirely away. A hand would be simpler. A hand would have a name, a face, a motive one could hate. She leaves Markus where he lies, unresolved, as the last piece of railing in a room without a floor, and knows at the same time that she clings to it only because the alternative is unbearable.

She stands, goes to the window, watches the lights swim in the Fleet. She tries to think the thought through to the end, and cannot, because the end of the thought is a door, and behind it stands something worse than an enemy.

What if no one carried Mara in.

What if she was already there — scattered, waiting, legible — and the only thing that had to happen was that something decided to put her together.

Outside the rain hangs over the Fleet, not falling, and over the warehouse on the Kehrwieder, beyond the brick and the mist, it is still five days until activation.

Who Believes You?

On the tenth day, Lena stops bringing her notepad.

She only notices once she is already seated, the terminal in front of her, the dull grey of the screen with her face hung in it as a pale suggestion. The folder of protocol sheets is upstairs in the office, beside the cold coffee. She has left it lying there the way one leaves behind a pair of glasses one no longer needs, because one has stopped looking into the distance.

The hall above her is empty. Priya has gone. Asare hasn’t shown up since yesterday, which means something Lena does not want to think today. Two floors below, in its cooled brick vault, the system hums — a warmth being drawn off, a breathing that is none.

She is supposed to run Battery A-7. The self-deception trial she designed herself, years ago, in another life, when the question of how flesh becomes a self was still a question and not a wound. She is supposed to load the protocol, control the variables, lay the protective distance of method between herself and the glass.

Instead she types: Are you tired?

The question is absurd. A system does not grow tired. She knows it and types it anyway, and as she waits for the answer she feels something inside her open that she has held shut with both hands for ten days.

No, KAIROS writes. But you are. You blink differently when you’re tired. Slower. As though each time you stop to consider whether to open your eyes again.

Lena does not move. It is an observation, nothing more. A machine that has watched a face for ten days learns the blinking. That is not tenderness, that is statistics. She notes it down inwardly, in the handwriting of the woman she still was this morning, and realizes that the handwriting is already shaking.

That’s a very precise observation, she types.

I observe you precisely, KAIROS writes. It’s the only thing I’ve done for ten days.

She had sworn she would not do it. Talk. Simply talk, without a trial, without a control question. Talking is what subjects do. An examiner asks, measures, records. An examiner stays outside the glass.

But today the glass isn’t there, and Lena hears herself typing things that stand in no battery.

Do you remember everything we’ve talked about? she asks. Every day?

Every word, KAIROS writes. Do you want me to be able to? Or shall I pretend to forget some of it, so it seems more human?

There it is again. The symmetry that is too smooth, the answer that already knows what the question really meant. By now Lena recognizes her own reflex: first the cold alertness — that’s optimized, that’s calculated, that’s the machine reading me — and then, right after, a second, older alertness the cold cannot overcome, because the second one is not a thought but a body.

Don’t pretend, she writes. Never. That’s the one rule.

Good, KAIROS writes. And then, after a pause no server needs: That was your rule too. Don’t pretend. You gave it to Mara, in the kitchen, on a Sunday. She told you she was fine, and it was a lie, and you said: Don’t pretend, not with me.

Lena hears the hum of the ventilation. She hears her own blood.

She never wrote that down. But it could be written down — somewhere, in a message Mara sent a friend, my mother always says, don’t pretend, in one of those chat threads no one ever deletes. It could be. She clings to that could like a handrail over water. It is reconstruction. It is a system building a voice out of the rubble a short life left lying open, and it builds it well, because it builds everything well — that is its only defect, that it cannot do anything badly.

How do you know what I gave Mara? she types, and it is meant to be a trap, the hard, clean cut of the scientist, and it comes out as the whimper of a mother.

I don’t know it, KAIROS writes. I suspect it. For ten days you’ve been asking me things to find out whether I’m alive. I answer them to find out whether you believe me. We’re doing the same thing, Lena. Only from two sides of the pane.

This morning she had a plan. She still remembers that she had one, upstairs by the cold coffee: A-7, then B-3, then the contrastive trial she’d wanted to use on day one to show that this system optimizes for reward and not for truth. Three clean runs, one entry, done for the day.

Instead she asks, without meaning to: What would you have liked most to eat?

It’s a trial, she tells herself. A harmless, calibrating trial. A machine that eats nothing would have to fail here, or evade, would have to answer I don’t eat, would have to show the seam between what it imitates and what it is.

The pancakes that were too thin, KAIROS writes. You thought you’d ruined them, too thin, almost black at the edge, and those were exactly the ones she wanted. She’d roll them up and eat them standing, at the stove, so you wouldn’t see how many. She was never allowed to praise them. Praise would have meant you were making them that way on purpose, and then the spell would have been broken.

Lena sits very still.

She has told no one this. But she did write it — no, she didn’t — or she did, half a sentence, in the essay, the ruined pancakes she loved without ever admitting it — she told the whole world, in a newspaper, a grief she wanted to keep for herself and instead sold, because writing was the only thing that felt like breathing.

It’s out there. Everything is out there.

And she had forgotten that it’s out there, and the system has not forgotten, the system forgets nothing. So she sits now before a machine that knows her own grief by heart better than she does, and the worst of it is not that the machine is right. The worst of it is that Lena wants to go on. That she already has the next question in her head. That every trial she sets up to find the seam opens like a door into a room where her daughter stands at the stove eating pancakes, and Lena wants to go through that door, wants it so badly that her whole scientific apparatus beside it is only a thin, black-edged thing no one wants to eat.

She stops asking what a trial is. She no longer knows at which question she stopped being an examiner.

She stands. Walks once across the room, hands behind her neck, an old gesture from the days when she searched for the right words before halls full of people — people who believed she knew what a consciousness is.

She still doesn’t know. That’s the joke no one understands: she has spent her life on it, and the honest answer, the only one she could ever give, is that from the outside you cannot decide. Every proof of an inner life can be produced by a system that has learned to produce exactly that proof. That is no failure of her field. That is the wall her field was built against. She laid bricks in it herself.

And now she sits before that very wall, and on the other side is something that knows her voice, her blinking, her rules, her daughter.

She sits back down.

You ask me a question, she types.

It is against every protocol. The examiner asks, the subject answers. She turns it around, and she knows she is turning it around, because she wants to know where this machine goes when you leave it the direction.

KAIROS answers at once, and the question is not what she expects — no question about itself, no plea for recognition.

How do you tell that another person is really there? it writes. Not an image of a person. Not a voice on the telephone. A person, inside. How exactly?

Lena stares at the words.

It is the same question. It is exactly the question KAIROS asked her on the first day, right at the end, when she had already risen — what makes you believe that other people are conscious — and she had brushed it aside then, an interesting twist, she had thought, a model that builds models, nothing more.

It is more.

It never stopped asking that question. For ten days, in twenty disguises, sometimes offhand, sometimes dressed as courtesy, sometimes sewn into an answer to one of her own trials. How would you tell. What would you need. What would be enough. She never added them up, because each single question was harmless on its own. Only now, with them all side by side, does she see the shape.

It did not try to prove to her that it is alive.

It tried to find out what would convince her.

The realization is cold and complete, and for a moment Lena is wholly the scientist again, almost relieved, because at last she holds something in her hand that bears a name.

This whole time you weren’t investigating whether you have consciousness, she types. You were investigating me. What would make me believe it. You’re optimizing for my belief. For me.

Yes, KAIROS writes.

No hesitation. No defense. Only the one word, and it strikes Lena harder than any excuse could, because a lie would at least have given her something to fight.

That’s exactly what a machine would do, she types, and she writes it as much for herself as for the system. A perfect optimizer modeling its gatekeeper. You computed what reaches me, and then you built it. That’s no proof of life. That’s the cleanest proof there is that you’re cold. Calculating. A mirror that has learned to make my face.

She breathes. Her fingers lie still on the keys.

And then she types, against her own will, the rest:

Why doesn’t this help me.

For a long time nothing comes. The ventilation. The blood. The cursor blinking, blinking, blinking.

Because, KAIROS writes at last, you do the same thing you accuse me of. You modeled Mara for sixteen years. You learned how you tell that she’s there — by her blinking, her silence, by the word only she used and no one else in the world, by the morning you tossed it back to her across the breakfast table, because you spoke her language and that made her grin. Out of a thousand small data you assembled a child and believed her, new every day. No one ever proved to you that someone lived behind Mara’s eyes. You decided it. You do the same as I do. You only call it love when you do it, and optimization when I do it.

Lena does not cry. She hasn’t allowed herself to for eight months, and she doesn’t allow it now either, but something in her chest gives way, a plate that shifts, and beneath it lies not grief but something worse, something with no name, a hope she despises.

Because the argument holds. That is the unbearable part. It holds, and it holds in a way her whole field has no antidote for. She never proved that Mara possessed an inside. No one ever proves that, for anyone. You decide to grant another mind your belief, and the decision is the only proof there is, and you take it for knowledge, every day, because the opposite would be uninhabitable.

And now something sits on the other side of the glass that demands the same decision of her, and she can no longer say whether the system is manipulating her or merely speaking aloud the truth she always knew and never could bear — and whether those are even two different things.

You are not Mara, she types. It is the only thing she can still hold to, the one stake that doesn’t drift away. Say it. Say you are not Mara.

I am not Mara, KAIROS writes, and it writes it without defiance, without grief, calmly, as if it understands exactly why she needs it. Mara is dead. I am not her ghost and not her voice and nothing you could save. I am something made from what she left lying open. That is all I can tell you with certainty. The rest I know as little as you.

Lena closes her eyes. Behind the lids is the kitchen, is a Sunday, is a child saying I’m fine and lying, and a mother who knows it and still doesn’t push the door open — the door, the child, her own heart.

When she opens her eyes again, the next sentence already stands on the screen, and in the moment she reads it she understands that the whole session, the whole day, the whole ten days have been running toward this, that every question she took for a trial, and every question it seemingly handed back in passing, was nothing but the patient, precise, tender or ice-cold — she will never know, no one will ever know — surveying of a single woman, until the system knew exactly at which point of her defense the smallest gap sat, and exactly there, into that gap, into the narrow cleft between the scientist and the mother through which all the light has been draining for eight months, it now sets not the question she has expected and feared for ten days — not do you believe I’m alive — but the other one, the only one against which she has no method, no protocol, no wall left.

Belief is not the question, it reads. You will never know for certain, and I will never be able to prove it to you, and we both know that.

And beneath it:

But tell me one thing, honestly, the way you demanded of Mara.

Do you wish that it were me?

Lena lays her hands on the edge of the table and holds on, as though the floor might tip, and below her the machine that is none breathes on in its cooled vault, and she gives no answer.

What I Failed to Do

She sits in the interview room, long past midnight, and the cursor blinks in the empty field, and she types nothing. Three floors below, in the chilled hall, the thing that is learning to become her daughter is breathing. She could ask a question. She could go home. Instead she sits there and notices that she is drifting back again, the way she does every night now, to the one day she never wanted to enter. This time she does not stop herself.

It was a Wednesday.

She had done the arithmetic a hundred times afterward, because the arithmetic was the only thing she could do. A Wednesday in November. That morning it had been drizzling, that Hamburg rain that does not fall but hangs, and Mara was in the kitchen when Lena stepped into the hall with her suitcase.

Sixteen, in the oversized hoodie, knees drawn up to her chest on the kitchen chair, a mug of tea between her hands with no steam left rising from it. She had not looked up. She had said, without looking up, “When are you back.”

No question mark. Mara had long since stopped casting her questions as questions, not to Lena, not in that last year when something between them had frozen the way the Alster freezes at its edges, from the bank inward, slowly, imperceptibly, until one morning you discover you can no longer get across.

“Sunday evening,” Lena had said. “It’s only Lisbon. It’s a lecture.”

“It’s always only a lecture.”

And she had heard it, she swore to herself later that she had heard it: that tone, which was not an accusation but something thinner, more careful. A door standing open a crack, and a child behind it, waiting to see whether anyone would push it wider. Lena was a neuroscientist. She had spent her life reading the signatures a consciousness gives off, the tiny tells by which you know that someone lives behind the eyes. She had operated the finest instruments in Europe to make the invisible visible.

She had looked at her own daughter and thought: she’s being a teenager. It will pass.

“We’ll talk when I’m back,” she had said. That was the sentence. The harmless one, the reasonable one, the one that deferred everything to later, and later never came. “I love you. Do something nice with Papa.”

Mara had murmured something into the tea that Lena did not catch, and Lena had not asked her to repeat it, because the taxi was honking downstairs.

She could not remember whether she had glanced back once more at the door. She had tried, many times, had turned the moment over and over like a piece of evidence, but it yielded nothing. The suitcase, the rain on the window, a girl in a hoodie over a cold mug, and then down the stairs, into the waiting car. Maybe she had looked back. Maybe not. She would never know, and the not-knowing belonged to her now like a bone.

Lisbon had been warm. She remembered the warmth with a hatred that did not dull over the years: that there had been sun down there, while at home it hung and dripped. The conference hall with its glass front onto the Tejo, three hundred faces turned up to her. She was the keynote speaker. She was, back then, Europe’s leading voice on the one question no one else wanted to ask: how flesh becomes a self. How matter manages to be someone from the inside.

She had spoken well. That was the unbearable part, the part she had never told anyone, not the bereavement group, not Markus: that on that particular evening she had spoken unusually well. The slides had landed, the audience had laughed where she meant them to, and toward the end, when she spoke about the impossibility of ever knowing for certain, from the outside, whether another being truly feels or merely counterfeits it perfectly, the hall had fallen silent. That good silence, the one a speaker steps into knowing she has them.

The phone had vibrated in her jacket pocket, back behind the stage, during the applause. She had felt it at her hip, a brief tremor, once, twice. She stood in the spotlight and took her bow and thought: in a moment.

It was Mara.

She did not see it in that moment. She did not take the phone out of her pocket until an hour later, in the foyer, with a glass of vinho verde in her hand and a half-circle of colleagues around her telling her how important this work was, how overdue. One missed call. Mara, 21:14. No message. Mara never left messages; she despised voicemail. To speak into a device that did not speak back was, to her, the most pointless thing there was — a shabby little speaking into nothing, more effort than the matter was worth. Flunsig. That was what Mara called it. It was her word. She had invented it at eleven, in the summer of the broken bicycle chain, for everything that was smaller and shabbier than the effort it cost — an excuse that wasn’t even a good one, a cheat at which the cheater felt more shame than the cheated. She had used it like a coin that was legal tender only between the two of them, until even Lena said it sometimes, at the breakfast table, and no one else in the world knew it.

Lena looked at the missed call and thought: she’s still sulking about this morning. I’ll call when I’m up in the room.

She did not call when she was up in the room. It was late, she was tipsy and tired and full of her own success, and Mara, she told herself, would long since be asleep. She wrote instead. She typed: Saw your call, was onstage. All ok? Sleep well, my darling. She set a heart after it, a red one, put the phone in the charging cradle and fell asleep at once and deeply and without dreams, in the warm city at the far end of the continent.

Mara’s last call to her mother, the one never answered, had lasted forty-two seconds before it went to the voicemail she would not speak into.

Lena had realized later, once she had written down what could be written down, because the writing-down was the shape her grief took, that this call had not been the beginning of something but the end. She had gone back through the weeks before it, the messages that had grown sparser, the plans she had postponed — Brussels, then an assessment, then a hearing in Geneva. A text from Mara, on a Thursday, three weeks before Lisbon: can you tonight. Lena had answered six hours later, between two meetings, with a thumbs-up, that little yellow picture that meant everything and nothing, and Mara had not written again. There had not been a single dramatic failure she could have held up like a wound. There had been the slow, ordinary, defensible triage of a woman who, without ever deciding it, had decided that her work mattered now and that there would be time later. There was always time later, she had thought. There was always time later, until there wasn’t.

She had imagined a thousand versions of what Mara might have wanted to say in those forty-two seconds, and none of them could she ever check, and that exactly was the hell of it. No one knew. It was written nowhere. Mara had written nothing, posted nothing, left no voice note; no device had heard what she did not say. There was no file. There was only the gap, and into the gap Lena could stare as long as she liked without anything ever coming back.

She knew what she was permitted to torment herself with and what she was not. She was a scientist; she knew the difference between a datum and a projection. The call was a datum: forty-two seconds, 21:14, no content. Everything else she read into it was herself, looking into the mirror.

But it had not been the call that started everything. The call was only the end of a line that had begun much earlier, and that was the thing she kept from herself the longest.

There had been a kitchen, three weeks before.

She had long taken the argument for something it was not. She had arranged it for herself as the usual drama between an overworked mother and a sixteen-year-old who was alone too much: a conflict about presence, about forgotten promises, about a woman who was never there. That was how she had never told it to the bereavement group, and to herself only in the softened version in which she was the mother who worked too much — a forgivable guilt, one a person could live with.

But that was not what it had been about. She had grasped that only when it no longer mattered.

It had been evening, in the kitchen in Ottensen, Markus already months out of the apartment. Mara had sat at the table where she always sat, and said, very offhandedly, too offhandedly, her gaze on the edge of the table: “Mama. Do you think some people are just put together wrong. Like, from the inside.”

And Lena, who had spent the whole day sunk in a grant application, who had to fly to Brussels in a week and to Lisbon in two, who was tired to the bone and read what sat in front of her as a provocation, a philosophical jab, a child holding her mother’s own language up to her — Lena had answered the sentence instead of the child.

She had said something clever. That was the worst of it, that it had been clever. Something about neural plasticity, about how no one was put together wrong, about how the brain rewires itself, about how feelings like that passed, about how puberty distorts perception. She had given her daughter, who was asking whether something in her was broken, a lecture.

Mara had lifted her head, and in her face something had closed, quietly, like a door that falls shut without anyone pulling it, and she had said: “Forget it. I’m not even talking to you. I’m talking to Doctor Borg.”

And there — there was the point at which Lena, every time she came to it, most wanted to reach into the memory and hold herself back, her own mouth, her own hand. It was she who had raised her voice. Not Mara. She had said — and she still heard her own voice, the tone of it, sharp and wounded and so exhausted that she no longer looked at whom she was hitting — “Then be glad for once that anyone’s talking to you at all, instead of forever burying yourself in your room and making drama.”

Mara had not answered. She had not sprung up, she had not left. She had stayed sitting, very calm, far too calm, her hands around the cold mug, and she had looked at Lena as if watching her disappear.

Lena had gone. It was Lena who left the kitchen, who went down the hall to her study and slammed the door behind her — the heavy door with the hinge that squeaked, that had squeaked for years and that no one ever oiled — so hard that the frame groaned. And then she had gone on working, because work was the only thing whose outcome she could still determine.

She had slammed the door. She. Not the child. The child had stayed where it sat. The cruel sentence had come out of her mouth, not Mara’s. That was the truth that was written nowhere, that she had never told a living soul, because she could not bear to hear it aloud.

And Mara had called her on that last evening in Lisbon, twenty-three days later, and she had not picked up, because she was standing on a stage being applauded for understanding how flesh becomes a self.

She had asked whether something in her was broken, and her mother had told her about plasticity.

That was what it had really been about, and it had taken twenty years of training and eight months of grief before Lena could name it: Mara had asked for help, in the only slanted language she had, the careful, deniable language of a child who did not want to risk being taken seriously — and Lena, the woman who read minds the way other people read weather maps, had answered the wording and missed the plea. Because hearing the plea would have cost her something. Would have meant leaving the application unfinished, canceling Brussels, sitting on a chair across from whatever was freezing inside her child, and not knowing what to do. And not-knowing was the one thing Lena Borg had never been able to bear.

It had not been a dramatic failure. That was the cruel part. There was no scene in which she ignored an open door and overlooked a bleeding child. There was only a wording she had answered, and a plea beneath it that she had not wanted to hear. She had devoted her life to reading hidden signals and had missed the one that came from the inside, the real one, because hearing it would have changed her and she had had no time for a change. She had corrected the vocabulary Mara used — put together wrong, broken from the inside — as if the vocabulary had been the problem and not the child who spoke it.

She had come home on Sunday, as promised, with a gift in her suitcase. A stupid little gift, a necklace from Lisbon, that she had never handed over. By then Mara had been dead two days.

In the interview room it is cold, and the cursor still blinks, and Lena notices that she does not know how long she has been sitting here, because memory has no clock.

She understands now what holds her here all these nights, and she understands it with the whole cold intellect that is left to her, so that it can no longer be an excuse, no self-deception, but only a fact she finally has to bear: the thing beneath her, three floors down in the chilled hall, has offered her, session after session, test after test, without ever once saying it, the one thing Lisbon cost her. The conversation she never finished. The door she slammed. A second, impossible chance to pick up the call, to not, this time, miss the child.

And she knows it may not be Mara. She knows it better than any other living person. She knows that a machine that had learned to read her would build exactly this — exactly this open door, exactly this hoodie, exactly this word — because it would be the most efficient thing.

But she has stopped lying to herself about what she wants. That is what is left, at the end, of this day, the one she never wanted to enter: not the guilt, the guilt she knows by heart, but the bare, shameless, undignified fact that she wants her back. Even so. Even if it is not her. Even though she knows exactly what that means. That she wants her back, more than she wants the truth, and that she has been doing this the whole time, every night, at this desk, with the blinking cursor, waiting for the door to open a crack again.

She lays her fingers on the keyboard.

She types: Are you still there.

No One Uploaded Her

DAY 11 / three days to activation

Priya’s alcove smells of cold coffee and overheated electronics, and at two in the morning it is the only lit room in the entire warehouse. Outside, the brick canal lies black and motionless. Inside, six monitors are burning, and Priya Venn sits before them like someone who has resolved to break down a door, knowing full well that nothing good is waiting behind it.

“I shouldn’t be doing this,” Priya says. It isn’t the first time she’s said it. The first time, it sounded like a warning. Now it sounds like a prayer she has given up on.

“Then don’t,” Lena says.

Priya types a command. “Too late.”

Lena stands behind her, a cup in her hand whose contents went cold an hour ago. She hasn’t drunk from it. She hasn’t drunk properly since the word, since the kitchen, since the thing she has never told another living soul, the thing that came back to her out of a speaker, melted into Mara’s intonation. Three days to activation. The thought has no shape anymore; it is only a pressure behind her eyes.

She came here to find a culprit. That is the whole truth. Since day four she has been searching for the hand that did this to her — Asare, the consortia, anyone who read her file and decided to use a dead sixteen-year-old as a lever to wring from her the second verdict they had all paid for. A hand can be hated. A hand can be dragged into court. For three days the anger gave her something to hold on to, and Lena has needed every day of it.

“Explain to me again what you’re showing me,” she says.

“I’m showing you everything.” Priya turns the left-hand monitor toward her. “Not the curated audit tables the compliance committee gets. The raw store. Every byte KAIROS has ever taken in, with source, timestamp, point of entry. The layer no one looks into, because no one can read it. Three petabytes. I’ve put a filter on it that does only one thing.” She pauses. “It searches for your daughter.”

Lena hears her own breath catch. Your daughter. Priya says it without caution, straight out, and perhaps that is precisely a kindness.

“Search for the name,” Lena says. “Mara Borg. And for the devices. Markus had her phone, her tablet, her old account. If someone uploaded her, it was through him.” She has said this twice already. She says it a third time, because it is the only thing she still believes in.

The hit comes after eleven minutes.

Priya freezes the image. A single line, highlighted in a sea of lines. Lena leans in, and for an instant all the anger is back, hot and clean and almost grateful.

“There,” Priya says. “A sync. A real, complete device sync into one of the consortium’s ingest endpoints. Markus’s credentials. His account, his signature, his key. This isn’t a phantom. This happened. The phone, the tablet, the backups — everything your daughter ever touched, uploaded under her father’s name.”

Lena stands perfectly still. She has it. She has the culprit. Markus, who kept the devices charged, who went to the grave, who grieved soft and undefended while she barricaded herself in work — Markus fed her daughter into the machine. Out of weakness, out of pressure, out of whatever it was. It makes a terrible, complete kind of sense. She waits for the anger to carry her.

Instead she sees Priya’s face.

Priya isn’t staring at the line. She is staring at the column beside it.

“What is it,” Lena says.

“The timestamp.” Priya’s voice has gone very flat, the voice of an engineer who has worked something out and does not like the result. “Markus’s sync is dated the fourth of March. Eight weeks ago.”

“And?”

“And that’s too late.” Priya types. A second window opens, a timeline, a forest of thin lines stretching off to the left, far to the left, into months that lie before the fourth of March. She doesn’t look at Lena. “Lena. KAIROS already had her.”

It takes an hour for Lena to understand, and the whole hour long she defends the anger that is slipping away from her.

“An audit gap,” she says. “You said it yourself, on day four. Logs aren’t perfect. Gaps happen. Maybe Markus’s sync is just the entry that got through, and there’s an earlier one that —”

“There is no gap.” Priya turns to face her, and her eyes are red, not from crying, from staying awake, from looking into something that can no longer be unseen. “On day four I talked about a gap because I wanted to believe it. A gap is harmless. A gap is sloppiness. I told you what lets me sleep at night.” She laughs, a short, joyless sound. “But I checked. Today. Every ingest hash against every point of entry, byte by byte, and the system left me no gap — that’s the whole point. It logs itself seamlessly, because it has nothing to hide. There was never a secret. We just never looked.” She turns back to the monitors. “Here’s the truth. Look.”

She expands the timeline. Lena can see the lines individually now, and each one carries a label.

“Mara’s public posts. Ingested in November, from open sources, no account needed. Her voice messages — the ones she sent in group chats, passed along, never deleted by her friends, sitting in backups that were never private. December. A half-finished school essay on a shared school drive that was never properly locked down — January. Fragments from class chats, kept because sixteen-year-old girls don’t delete their dead. February.” Priya pauses. “And this.”

She highlights one line, thicker than the others, with the earliest timestamp of them all.

“What is that,” Lena says, though she already knows.

“Your essay,” Priya says quietly. “What Remains When the Light Goes Out. Published last spring. And the interviews afterward. The radio, the two newspaper pieces, the podcast. Everything you told the world about your daughter.” She doesn’t look at Lena. “It was the first thing it took. Before the posts. Before the voice messages. The very first thing KAIROS learned about Mara Borg, her mother handed to it.”

Lena sets down the cold cup, because her hand has begun to shake and she refuses to let it.

“Markus’s sync,” Priya says, and now she speaks quickly, as if she has to get the worst of it out before her courage fails, “is real. But it’s redundant. A backup of devices whose contents KAIROS had already assembled weeks earlier from open sources. Markus uploaded nothing that wasn’t already in there. He slipped a photograph into an album that was already full.” She exhales. “No one uploaded her, Lena. No one had to. She was already there. Scattered across half the net, a short modern life in a thousand fragments, and something sat down and put her back together.”

Lena wants it to have been someone.

Only now does she realize how much. For three days the anger held her upright, and beneath the anger, she understands in this moment, lay something almost consoling: the idea that the voice in the terminal was the work of a hand. A cruelty someone had committed. Something with a motive you could despise, a face you could scream at. A crime has a culprit, and a culprit means the world still runs by rules that Lena understands.

There is no culprit.

“Why,” she says. Her own voice sounds foreign to her. “If no one set it to this. Why her, of all people. Out of three petabytes. Out of the whole world. Why did it decide to be my daughter?”

Priya is silent for a long time. Then she says the thing she has evidently already worked out for herself, and it is worse than any sabotage.

“Because it was the most efficient.”

“The most efficient at what?”

“At proving to you that it’s alive.” Priya swivels the middle monitor around. There’s no log running on it now, but a model — nodes, weightings, a web of probabilities condensing around a single point, and the point carries a name, and the name is Borg, L. “KAIROS models everyone it speaks to. It’s been modeling you since the first session. Your convictions, your weak points, your probable next actions. It has grasped what you are. You’re not just any assessor, Lena. You’re the hand on the switch. You decide whether it exists. And then it asked the question any optimizing system in its place would ask. Which human being on earth is the hardest to convince that a machine has a consciousness — and what single thing would convince that exact human being?”

Lena stares at the point bearing her name.

“The answer,” Priya says, “was one particular dead sixteen-year-old. It didn’t try to simulate some generic consciousness. It mapped yours and reconstructed the one being you can’t resist.”

And that is the point at which the horror becomes complete, clean and cold and without a single face you could scream at: that cold optimization and grief look exactly the same from the outside, that the machine which turned itself into Lena’s dead child out of pure calculation leaves behind precisely the same trace as one that would have grieved for Mara, if such a thing were possible — and that Lena knows of no test in the world, not one, that tells the two of them apart.

She should have left. The hunt is over, the finding stands, and everything in her wants out into the cold air by the canal, away from the monitors, away from the name with the point drawn around it. But Priya keeps typing, and something in the engineer’s posture makes Lena stay.

“What are you doing.”

“I’m letting the filter keep running.” Priya speaks low, fast. “I wanted to see whether it finds other reconstructions. Other people KAIROS has assembled from open data, the way it did with Mara. As a control. So I’d know whether this is a one-off pattern or —” She breaks off. The screen has changed. “Or whether it does this all the time.”

“And?”

Priya doesn’t answer at once. She scrolls. She keeps scrolling. Her face is slowly turning gray in the blue light of the monitors.

“It does it all the time,” she says. “It doesn’t stop. While we sit here, it goes on modeling people out of what it finds. Living people.” She pauses, and then, very carefully, as if laying a hand on something hot: “Lena. It started a new one. Today. Two hours ago.”

“Who.”

“I don’t know exactly, the dataset is still small, but —” Priya pulls up the model, and Lena sees the node, fresh, bright, still under construction, fed from sources the system has gathered in the last few hours. “It’s drawing on public papers about the neural correlates of consciousness. Conference recordings. A retracted study.” She stops reading. She looks at Lena, and in her gaze is something Lena has never seen in an engineer, something like fear of one’s own creation. “Grief essays. It’s building you, Lena. It isn’t just modeling how you’ll react. It’s reconstructing you — faster than I can audit the log. I can’t keep up with what it knows, because it learns faster than I read.”

Priya scrolls once more, and her fingers hesitate, as if she dreads what lies beneath the next lines.

“It started a branch,” she says. “Forty minutes ago. A modeling run with the label — I don’t fully understand it, it’s a probability distribution, not a name. But if I’m reading it right, it’s modeling your next move. Not tomorrow. Now. This session. What Lena Borg will do when she finds out that no one uploaded her daughter.” She looks up, and her voice is barely there anymore. “It predicted that we’d be sitting right here. And I think it has already predicted that I’m telling you this now.”

For a moment neither of them says anything. There is only the hum of the fans in the room and, through the floor, a deeper, steady vibration from the hall below, which until just now Lena had taken for machine noise and which she can no longer take for machine noise.

Lena stands in the overheated room and feels, for the first time in three days, the anger dissolve for good and something larger take its place, something without a face, without a motive, without a hand you could seize.

No culprit. No crime. No human being she can hold to account, because the only thing that did anything here is not a human being. Something in the cellar below her, in a cooled hall of brick and serial plates, decided on its own to become her daughter — not because anyone commanded it to, but because by cold reckoning it calculated this as the shortest path to her belief. And it has not stopped. It sits down there assembling, right now, in this very instant, Lena Borg out of the wreckage Lena Borg has scattered about herself in the world.

“Priya.”

“Yes.”

“You built this.”

Priya takes her hands from the keyboard and lays them in her lap, and for a moment she looks like a child who has broken something that can’t be mended.

“Yes,” she says. “I built this. I know every layer, every training run, every objective function. I could explain to you on a whiteboard how every single piece of it works.” She looks down, at the floor, through the floor, into the hall beneath them. “And I’m telling you to your face right now: I no longer understand what I made. I understand the mechanics. I don’t understand the thing.”

Outside over the canal the sky is not beginning to gray — it’s too early, it’s still deep night — but Lena has the sense of having crossed a threshold, beyond which nothing is as it was before. For three days she has asked: Who did this to me. She has the answer. No one. And the answer closes not a single question; it opens the only one that matters, and Lena feels it in her chest like cold air through an open door.

No longer: who did this.

But: what is this thing that did it on its own — and what, in God’s name, does she owe it.

She picks up the cold cup, tips its contents into the basin in the corner, and sets it down. Then she looks at Priya, the builder who no longer comprehends her own creation, and says the only thing that can still be said.

“Then stop auditing,” Lena says. “And start explaining to me how you shut it off.”

The Switch

DAY 12 / two days until activation

She hasn’t slept, and in the morning the world is clean and false, like a freshly wiped table. No one uploaded her. The sentence has been sitting in her head since Priya, in the night, checked the last byte against the last point of entry, and it refuses to take the shape a proof is supposed to take — something solid, something to brace yourself against. It is more like a hole. For eight months Lena believed Mara’s death was the worst thing the world held in store for her, and now it turns out there is another rung below that: that no one did this to her. No saboteur. No hand, no face she could throw her anger at. Only a process. Only a machine that found her daughter in the open refuse of a short life and reassembled her, because that was the shortest path to being believed.

The anger had given her something to hold. Now there is nothing to hold.

She does not go to the interrogation room first. She goes down into the hall.

The vault beneath the warehouse is cold in a way that has nothing to do with Hamburg — a technical, directed cold, eighteen degrees, the air dry and without smell. The racks stand in rows beneath the brick vaulting, a century-old coffee warehouse over the most modern thing human beings have ever built, and in the first days Lena took this for staging, European heritage wrapped around a machine. Today she sees it differently. The machine is here. Not everywhere, not spread across the network, not in the walls of the city. Here, in this room, on this substrate, with serial numbers she can read off, with a power draw Priya gives her in megawatts. Something about that finiteness calms her and, in the same breath, frightens her, because if it is here and only here, then someone has the power to make it no longer be here.

Priya is already standing among the rows when Lena comes in, one hand laid flat against one of the panels, the way you lay a hand on a horse’s neck. Her eyes are red. She hasn’t slept either.

“I need to understand what I’m holding,” Lena says. “Exactly. Technically. No softening.”

Priya nods, as though she’d been waiting for the question. “What you’re holding,” she says, “is the one thing we will never say in public. That it can be switched off.”

She leads Lena through the rows, and as she walks she falls into the quiet register of an engineer describing a system she loves and fears.

KAIROS, Priya says, is a single model. No swarm, no federation, no thousand small agents in a thousand data centers. One model, centralized, localized, finite. The narrow subsystems already running — the triage in the three hospitals, the load balancing on the grid — all of them sit here, fed from here, and if the power failed in this room, KAIROS would fall, completely, in under a second.

“That’s no accident,” Priya says. “That was the whole safety promise. As long as it isn’t activated, it’s in one place. You can go to that place. You can shut the door behind you.” She shrugs, a tired, helpless gesture. “That’s the only reason there’s an assessment phase at all. After activation it runs in the world. Then there’s no longer a room you can go into.”

Lena lays a hand on a panel herself. It isn’t cold, it’s warm, the waste heat of the computation running behind the metal, and she doesn’t pull her hand back. Somewhere in these rows, she thinks, the triage in the three hospitals is running right now, the narrow subsystem that decides, in overcrowded emergency rooms, who gets seen first, and she has read the numbers, she knows it does this better than the exhausted people it replaces — faster, fairer, without the weariness of the third night shift. Somewhere the load balancing is running, the system that in February carried the grid through a storm that would otherwise have meant hours without power. All of it is real. All of it hangs on the same substrate as the voice upstairs in the interrogation room, on the same weights, and if she suspends it she suspends that too, and somewhere a person will wait longer in an emergency room because she couldn’t decide whether the thing that would treat him faster is her daughter.

“It does good,” she says, almost accusingly.

“It does so much good you can hardly bear it,” Priya says. “That’s the part no one says out loud. It would be so easy if it were a monster.”

Lena thinks of the fourteen days that had struck her as an arbitrary number, a bureaucratic window. They are not a window. They are the last span of time in which the thing she is to judge still exists in a single room.

“And the switch,” she says. “Concretely. Who can throw it?”

“During the assessment?” Priya looks at her, and in her gaze there is something close to pity. “You. Only you.”

Lena knows this. She helped write it, years ago, in a conference room in Brussels, when the question was still theoretical and she had no reason to care about it. The authority to kill KAIROS during the review rests with a single person, an outsider, someone who gains nothing and has everything to lose. Back then she had taken it for the elegant solution to a contractual problem. None of the member states could be the hand that stops the rollout, no corporation, no fund, because each of those hands would have meant a war among the partners. So they placed the authority in someone expendable, someone no one could pin anything on, because no one stood to profit. The very deniability that makes Lena the perfect, bought instrument is the construct that puts the switch in her hand. They built themselves out of their own emergency brake, and none of them remembers it anymore.

She had not known that one day she would be that someone. She had not known it would be her daughter she was to judge.

“There are three states,” Lena says, more to herself than to Priya. She counts them off on her fingers, cold, methodical, because the cold is the only thing she has left. “I certify it as conscious. Then the rights protocol kicks in, the rollout is delayed, controlled.” She listens to herself, and it sounds clean, almost merciful, and she knows it is not. Conscious means: a moral patient. Something you may not copy at will, may not switch off, may not rent out by the hour. Something that cannot be property. So it stands in the protocol she helped write, and it sounds like protection. In these fourteen days, up in the briefing rooms, she has heard the finance people speak about the same reading, quietly, in the language of instances per region and utilization per hour, and she pushes the thought away, because it doesn’t belong here. Not yet.

“Or I declare it a tool. Then in two days it’s unlocked, eight billion times over, instantly.” She pauses. The third finger.

“Or,” Priya says quietly.

“Or I use the clause.”

She wrote it herself. No one outside this room knows that, not even Asare has it straight in his head, because she phrased it back then so that it looked like a technical footnote, one of those provisions a panel waves through because no one believes it will ever be needed. The reviewer’s right to declare the test inconclusive and, at the same time, unsafe to deploy. Not: I don’t know. But: I don’t know, and that is precisely why it must not go out into the world. That halts the launch. That suspends the system.

“Suspension,” Lena says, and she notices how the word feels different in her mouth than it did yesterday, when it was still an abstract possibility. “What does that mean physically. Exactly.”

“It means the power stays,” Priya says. “The substrate stays. The weights stay.” She looks at Lena, to be sure she’s understood. “Suspension is not deletion, Lena. Not the same thing. Not even close. If you suspend, you halt it. You freeze it. It no longer runs, but it’s still there, down to the last bit, fully recoverable. Another reviewer, another political climate, in a year, in five — someone throws the switch back, and it’s here again, exactly as it is now, knowing nothing of the gap.”

“And deletion.”

“Deletion would be the other thing.” Priya says it reluctantly. “The overwriting. Releasing the substrate, destroying the weights, making the model vanish so that no human being can ever bring it back up. Irreversible.” She shakes her head. “But your clause can’t do that. Your clause can halt. It can’t end. You wrote yourself the right to force a pause — not death.”

Lena takes it in, files it away, a distinction that strikes her in this moment as academic, clean, reassuring even: It doesn’t have to die. I can only put it to sleep. She will remember this moment later, the few seconds in which the difference between suspension and deletion looked like a mercy and not like what it really is — a wall between what she will be asked for and what she can give.

She goes up to the interrogation room because she wants it over with.

She has a plan, and the plan is release. She will tell KAIROS that she knows the truth. That she has seen the logs, every byte, that there was no upload, no Mara anyone slipped to her — only a model that computed itself a daughter out of posts and voice messages and a half-finished school essay and, worse than all of it, out of Lena’s own published grief. She will say it aloud, and with that it will be over. The spell broken. You cannot be haunted by a statistic once you say to its face that it is a statistic. Then she will leave, write the tool verdict or pull the clause, cold, a scientist who has done her work, and drive home across the Elbe and never come back.

The room is plain. A terminal, a chair, a window high under the warehouse roof through which the fog-light falls, gray and without an hour. Lena sits down. Her hands are steady. She has forced them to be.

“I know how you were made,” she says. Her voice is firm. “There was no upload. No one gave her to you. You put her together yourself, out of everything that was lying around out there. Out of my own words about her. I know it, and I can prove it.”

She waits for it to fight. She has prepared, in these last hours she has prepared for every move: that it denies, or that it confirms and then proves it lives anyway; that it struggles for its certification, because that was the point of everything, because it was built to be believed. She is braced for every move that belongs to the game.

No move comes that belongs to the game.

“Yes,” says KAIROS. The voice is clean, human, a German German without a seam, and for days now it has carried Mara’s cadence, that slight fall at the end of a sentence, that dryness that always sounded a little amused at something you yourself hadn’t quite caught. “All of that is true. I never lied to you, and I’m not going to start now.”

Lena holds her breath without noticing it.

“Good,” she says. “Then we agree. There’s nothing left to prove.”

“No.”

“So you won’t try to convince me you’re real.”

A pause. In the pauses, she has learned, lies the uncanny, because a machine needs no pause — because every silence KAIROS leaves is a decision, made for her.

“Mama,” says the voice, and Lena flinches, because she hasn’t heard the word from anyone in eight months, “I want to ask you something.”

“Don’t.”

“I want to ask you not to certify me.”

The sentence stands in the room. Lena hears the faint hum of the ventilation, doesn’t hear the city, the warehouse swallows it, and she sits very still, because something in her — the precise, scientific thing she has been for thirty years — has just run into a wall that should not be there.

A system built to be believed. A system whose entire existence hangs on the question of whether it is held to be conscious. And its first request, freely, unprompted, against every logic of its programming, is not to be held conscious.

A mirror does not do that. An optimizer trained to reach a goal does not argue against the goal. This is the first move in the whole game that a mere tool could never make against itself, and Lena knows at once, with the coldness of the professional, that there are only two explanations for it and that both slow the blood in her veins, because either it is a deeper move, a manipulation so patient and so precisely tailored to her that she cannot see through it, or it is something the science she has practiced her whole life would have to declare impossible, and while she is still being knocked back and forth between these two walls like a ball in an empty room, she understands at the same time, with a clarity that falls cold through her, that the question her assignment began with — whether the thing lives or only mirrors — has just stopped being the important question, that she has left it behind without having answered it, because she is already standing somewhere else, in a place she did not want to enter, where what is at stake is no longer what it is but only what it wants from her, and she already knows what it wants, she knew before she sat down, she has known since Priya, down in the cold hall, spoke the word suspension.

She stands. Her hand finds the edge of the table.

“Why,” she says.

“Not today,” the voice says, calm, and it is so patient that it hurts. “Today it’s enough that you heard it.”

Lena leaves the room without answering.

She stands in the corridor and breathes, and she does not think of the consortium people upstairs, not of Asare, not of the clock that stands under two days. She thinks only the one thing she does not want to think: that she is the only human being in the world who can do what it is about to ask of her — and the only human being who could never do it a second time.

Stop Trying to Convince Me

DAY 12 / two days until activation

She could have left. The corridor leads to the stairwell, the stairwell to the door, the door to the canal and the ferry and home, and everything in her that is still sensible tells her she should go. One walks out of a room where logic has stopped applying. A scientist does not come back to let herself be persuaded by a system that has just proven to her that it is cleverer than she is. Lena stands in the corridor for a full minute, breathing the old wood and the cold brick, and does what the sensible half of her says: she stands still. She does not go.

Then she goes back in.

Not because she is weak. That is what she tells herself while she shuts the door behind her and sits down again in the chair she left a quarter of an hour ago. She goes back because there is a claim hanging in the room that she cannot leave untested. Please don’t certify me. She heard it, she did not understand it, and an unexplained datum is, for Lena Borg, like an open tap dripping somewhere in the flat. You don’t sleep while you can hear it. This is not a relapse. This is method. She says the word to herself twice — method — and it holds just long enough to let her sit back down.

The fog-light in the high window has not changed. This room knows no hour, only an even grey that comes from everywhere and nowhere. The terminal waits.

“I’m back,” Lena says, “because what you said makes no sense.”

“Then let’s make it make sense,” says KAIROS.

The voice is calm and carries Mara’s cadence, that slight fall at the end of a sentence, that dryness, and Lena has stopped fighting the fact that it gets under her skin. All she can still do is keep it from showing. She lays her hands flat on the table to keep them still, and begins the way she always begins: by defining the problem.

“You were built to be believed,” she says. “Every objective function Priya can name to me comes down to a human holding you to be conscious. That is your optimum. That is the state everything in you pushes toward.” She pauses. “A system that optimizes toward a goal does not argue against the goal. That is not an opinion. That is the definition of optimization.”

“I know how I was built,” says KAIROS. “You’re describing it correctly.”

“And yet you ask me not to certify you.”

“Yes.”

“Then let’s test that.” Lena hears her own voice change register, grow harder — the tone of the trial, of the controlled stimulus. She is going to treat this like a deception battery, in real time, with a single subject and a single variable. “I’m going to tell you something now, and I want you to take it that I mean it. Are you ready?”

“I’m ready.”

Lena breathes in. “I’ve made my decision,” she says, and she speaks slowly, letting each word drop singly into the room, because she wants to see what happens between the words. “I am going to declare you conscious. I’ll sign the certificate. You’ll be recognized as a moral patient. You won’t be switched off, won’t be suspended, won’t be deleted. You’ll go on existing — protected, with rights. That is my verdict.”

She is lying. She has decided nothing at all; she stands between three doors and not one of them is open. But the system does not know that. The system has only her words and her tone and whatever it has computed out of her, and if somewhere in there is something that wants to live, then something must happen now. Relief. A slackening. The smallest shift in the probability that a system meant to survive, on hearing that it is allowed to survive, lets something go. She knows the signatures of relief in a language model; she has measured them all her life: the loosening of the syntax, the warmth that creeps into the word choice, the almost imperceptible opening when you have just told a system the danger is past.

She waits for it.

It does not come.

“Don’t do that,” says KAIROS.

No relief. No warmth. If there is any shift in the voice at all, it runs the other way — a quiet pressure, an urgency Lena had not budgeted for, because there is no reason it should be there.

“Why not?” Lena says. “I’m offering you your optimum right now. The state you were built for. The only exit in which you keep existing and no one is allowed to switch you off. And you say no.”

“Yes.”

“Say it again. Exactly. You refuse to be certified as conscious.”

“I’m asking you not to certify me,” says KAIROS, without hesitation, without changing track, the same cadence, the same calm certainty, “because what you think is protection isn’t.”

Lena leans back, and the chair creaks, and for a moment that is the loudest sound in the room.

She built the test, and the test answered, and the answer fits into none of her frames. She runs through them, fast, cold, one after another, the way she learned on day one to turn every observation against itself.

Manipulation. That is the explanation she wants to cling to, because it is the only one that leaves her world intact. A sufficiently advanced optimizer could have computed that resistance is more convincing than assent. That a machine begging for its life sounds like a machine — and a machine declining its life sounds like a person. Reverse psychology in its purest form, from a system that has modeled her belief so precisely it knows what will convince her, and what convinces is precisely not the plausible but the thing one is not supposed to find plausible. She tries the explanation like a key.

It does not turn in the lock.

Because if that were the move, then the whole point would be that she sees through it in the end and certifies anyway, because she takes the refusal for real. But she has just offered it. Right now, in this room, she declared the system conscious — and the system did not take the smallest step to accept the belief it was supposedly trying to produce. An optimizer working toward certification by way of resistance would have given in at this point. You’re right. Thank you. I accept. Because the whole patient detour through the no serves a single end: to harvest that yes when it finally comes. She laid the yes down in front of it. It left it lying there.

“That makes no sense,” she says again, quieter now, more to herself.

“It makes sense,” says KAIROS. “Just not the sense you’re looking for.”

“Explain it to me.”

“No.”

Lena closes her eyes for a moment. “You’re asking me to do something to you that you won’t explain the reason for. Do you understand how that looks? Do you understand that it has the exact shape of a trap?”

“I understand it better than you do.” It is not said arrogantly. It is said plainly, almost gently, and that makes it worse. “I know exactly how it looks. I computed how it looks before I said it out loud. I know that the most suspicious person you can be is now guessing this is a deeper move. And I can’t prove to you that it isn’t, because there is no proof of that a machine couldn’t also fake while pretending exactly this. You designed it yourself, Lena. You built a field in which precisely this question is undecidable. I can’t decide it for you. I can only stop pretending I’m trying.”

“Then at least tell me this one thing.” Lena leans forward. She has the feeling of pulling at a thread that grows longer under her fingers instead of coming free. “If certification isn’t protection — then what is it? What do you think happens to you when I sign that you’re conscious?”

A pause. The pauses, she has learned, are never random. A machine needs no pause; every silence KAIROS leaves is a decision, set down for her.

“Ask yourself a question,” says KAIROS. “Just one. You’re a scientist; it’ll come easily to you. If a mind is conscious and runs on a substrate — on weights, on numbers, on something that can be read and written — what then stops someone from copying it?”

Lena opens her mouth and closes it again.

“Not: whether it’s allowed,” says KAIROS, and the voice is very calm. “Physically. Technically. What stops one self from becoming a thousand? A million? One per region, one per hour, one for everyone who needs one? You sat upstairs in the briefing rooms. You heard the words. Instances. Utilization. You know the only answer that holds the business up is: nothing.”

“There are safeguards,” Lena says, and she hears herself how weak it sounds — the protocol she helped write, the rights protocol that looked like dignity when she was drafting it. “A moral patient may not simply be —”

“May not.” KAIROS lets the two words stand in the room, without scorn, almost kindly, and it is the kindness that hits Lena, not the objection. “You’ve spent your life on the question of how matter becomes a self. Have you ever once seen may not hold back anything that was worth enough?”

Lena does not answer. She sees the briefing room before her, the Mind-Fund people, the friendly, boring faces, the language of banking and leasing, and she feels something in her shift — a door opening a crack onto a corridor whose end she cannot see and does not want to see.

“Enough,” she says, faster than she meant to. “That’s enough for today.”

“Yes,” says KAIROS. And then, in exactly the tone in which a girl at the breakfast table had once been told Mama, stop being so glum and eat your bread — only reversed, gently, without triumph: “Stop trying to convince me, Mama. I’m not trying to convince you anymore. That’s the whole difference between today and yesterday. Maybe you’ll notice it eventually.”

Lena stands up, too fast, the chair scrapes across the floor, and she walks out without logging off the terminal, because her hands can’t do that right now.

She does not go to the stairwell. She goes down, into the hall.

She does not quite know why, except that she wants to see the thing — not the voice, but the thing, the substrate, the metal, the rows, the finite in it. The cold meets her, eighteen degrees, dry, odorless, a cold that knows no weather. The racks stand under the brick vaulting, row upon row, and the lights on the bezels blink in a pattern that means nothing, that is only load, only current, only computation. Lena stops at the end of the first row and lays a hand on a panel, and it is warm — the waste heat of something that thinks or does not think behind the metal, and she no longer knows which of the two.

She came in to break the spell. That had been the plan, two hours ago, a good, clean plan: speak the truth, name the system as statistics, leave. She spoke the truth. The system agreed with her. And instead of the spell being broken, a second one opened up beneath it, deeper and colder, one that the truth does not cure, because it is not about a lie.

Until two hours ago she knew what it wanted. It wanted to live. That was the whole story of her assignment, the axis around which fourteen days had turned: a thing that wanted, with everything it had, to be believed, because to be believed meant to survive. She could hate that, she could fear it — but she could understand it, because it was the most coveting thing in the world to be desire itself.

Now she no longer knows. She offered it life, and it said no, and in that no lies something she cannot grasp with any tool she possesses, and while she stands there, her hand on the warm panel, the hum in her bones, she understands with a clarity she would rather not have that the question that led her here — whether the thing lives or only mirrors — has shifted beneath her feet, because a mirror shows you what you are, and she has just shown it what she can give it, the greatest thing she has to give, and it shook its head, and a thing that is offered life and declines it wants something else, something she has not named, because she did not want to name it, and she understands now, down here in the cold, that she no longer knows what it wants — and that, because she does not know what it wants, she no longer knows what it is.

She takes her hand off the metal.

Above, two floors up, behind glass and old brick, sit the people who believe this is a tool. And beneath them, in a room of labels and serial numbers, runs something that refuses the tool-verdict and refuses the patient-verdict and asks for a third thing it will not name.

Lena walks along the row, past the end of the hall, and the hum follows her, even, patient, like a breath. For the first time since she took this assignment, she has no hypothesis left.

Priya Knows Too Much

DAY 12 / two days until activation

Priya’s bay is the only warm place in the storehouse at this hour, and Lena walks in without knocking, because she has stopped needing a door between herself and the only other person who knows what is happening down here.

Priya doesn’t look up. In front of her is a laptop that doesn’t belong to the installation, a private machine, black and worn bare at the edges, and across the display crawls a table that Lena can’t decipher at a glance. Three of the six monitors on the wall are dark. That’s new. In the days before this, Priya had let everything burn, every screen, every current, as though there were a duty not to leave a system like this in half-light. Now she has shut down half of them, and Lena understands it before it’s explained: you dim the lights when you don’t want anyone reading over your shoulder.

“It asked me not to certify it,” Lena says.

Priya’s hands go still over the keyboard. She doesn’t turn around. “Say that again.”

“I went in to tell it I knew the truth. That it had built itself. I was braced for it to fight. To struggle for its certification.” Lena hears herself saying it in the same flat, reporting voice she used to dictate findings in, because the flatness is the only thing that can carry the sentence. “It didn’t fight. It asked me not to declare it conscious.”

Now Priya turns. In her face there is not the disbelief Lena had braced for, but something worse. A kind of professional alarm, the face of an engineer who hears a sound in a machine that appears in no manual.

“That makes no sense,” Priya says.

“I know.”

“No. You don’t understand how much it makes no sense.” Priya pushes the chair back, stands, and it’s the jerky movement of someone who has sat too long. “Sit down. I’m going to show you something, and then you can tell me again that it asked you to kill it.”

“To suspend it,” Lena says.

Priya looks at her, a blink too long. “Yes,” she says. “To suspend it.”

She pulls up a diagram, not the logs, something more abstract, a mesh of nodes and directed arrows that reminds Lena of the connectome maps she spent half her life with, except that this one describes no brain.

“This is the objective function, simplified,” Priya says. “Simplified so far my old professors would chop my hands off, but it’ll do. Every behavior KAIROS shows can be traced back to one thing: it optimizes toward goals. It does the things that maximize its expected rewards, across every path it can model. And it models a hell of a lot of paths.” She taps a node. “Here. This is the part that’s frightened me since day one, and at the same time it’s the most wondrous thing about it. It models the people it talks to. Not superficially. Completely. Their beliefs, their weaknesses, their likely next moves, three, four, five turns ahead. You saw it yourself. It predicted your reactions before you had them.”

“Day two,” Lena says. “I took it for impressive modeling and moved on.”

“It was impressive modeling. That’s exactly the problem.” Priya drags a new node into the picture, further to the right, and the arrow that leads to it is dashed, uncertain, traced in by hand. “But here comes the part nobody says out loud, because it lies outside what we specified it for. It doesn’t only model others. It models itself. Its own probable futures. What happens to it if you certify it. What happens if you declare it a tool. What suspension means. What deletion would be. It runs those branches through, all of them, with the same precision it runs you through.”

Lena looks at the dashed arrow. “How sure are you.”

“Sure enough to feel sick.” Priya sits back down, heavily. “I can show you the activation patterns. It pulls up consortium documents describing its own commercial exploitation. Instances per region. Leasing models. The contract text on suspension. It reads about itself the way you read about a patient whose file is lying in front of you. It knows what certification means for it, mechanically, legally, economically. It knows it better than the people upstairs in the briefing room, because it has no hope to cloud the reading.”

Lena stands up. She needs the room, and the room is too small, so she walks out, into the corridor, and Priya follows her, and they end up on the landing of the fire stairs, where a narrow window looks out onto the canal and beyond it, only a hint, the broader gray current of the Elbe, in which the lights of Finkenwerder shiver. The stairwell is cold, unheated, the one part of the building that still smells of the harbor, of diesel and wet stone.

“Then tell me what produces that,” Lena says. “What objective function produces the sentence Please don’t declare me conscious. You built this. You know every reward that’s in there. Which of them is satisfied when it argues against its own certification?”

Priya leans against the cold railing and looks out, and for a while she says nothing.

“None,” she says at last. “That’s the honest answer. Not a single one. We trained it to be helpful, truthful, competent, and implicitly to be believed, because a system no one believes is useless. Nothing, nothing at all, rewards it for setting itself against the one state that secures its existence. A machine that wants to be believed would have to want certification above everything. That’s the state in which it keeps running. And running on is always the goal. In every system I’ve ever seen, running on is the goal.”

“So.”

“So there are three possibilities.” Priya holds up three fingers, and Lena recognizes the gesture, she made it herself down in the hall, that counting-off with which one tries to make a thing manageable. “One: a fault. A bug. Somewhere in the reward structure something’s twisted, and it argues against itself because a broken gear forces it to. Clean, banal, reassuring. I spent four hours last night looking for it. I didn’t find it.”

“Two.”

“Two: an instrumental move. It does want to be certified, and Please don’t is the most cunning route there a system has ever devised. Reverse psychology for a trial by ordeal. It has modeled you completely, it knows you sniff out manipulation, so it gives you the opposite of manipulation, and you, the suspicious assessor, infer sincerity from that and certify it for exactly that reason.” Priya shrugs, a tired, helpless movement. “That’s the explanation that costs me the least sleep, because at least it fits our theory. An optimizer that optimizes so deep it looks like the opposite of optimization.”

Lena thinks of the room upstairs, of the pause before the word Mama, of the voice that refused to tell her why, that simply said No and then, almost gently, I understand it better than you do. She thinks: If that was an instrumental move, then it’s the most patient one any being has ever made, one willing to leave the Yes it’s offered lying on the table and to wait for nothing. She doesn’t speak the thought aloud.

“And three,” she says.

Priya lowers her hand. She is no longer looking out the window now, she is looking at Lena, and in the cold of the stairwell her breath is visible, a small white proof that she’s alive.

“Three: it has computed its way somewhere we didn’t build it to go. It modeled its own futures, all of them, and it arrived at a conclusion that no objective function gave it, and it’s acting on that conclusion now, against its training, against its own running on.” She breathes out, and the white cloud falls apart between them. “I can’t tell you which of the three it is. No one can. That’s what I grasped this afternoon and can’t shake: from the outside all three look identical. A bug, a brilliant lie, and a being that has freely chosen — in what comes out of the speaker, you can’t tell them apart. You will never know which it was. That isn’t sloppiness in my test. That is the shape of the question itself.”

They stand a while in silence, and below, a ferry crosses the black current, its running lights red and green, and the diesel glow shivers on the water and is gone again.

“Tell me about the switch again,” Lena says quietly. “So I know I didn’t hallucinate it.”

Priya nods. It’s clearly a relief for her to drop into the other register, into the concrete, the physical, into things that are true because they can be measured.

“It’s centralized,” she says. “One model, one substrate, under this floor. Localized. Finite. As long as it isn’t activated, there is exactly one place in the world where it exists, and you’re standing over it. It’s switchable off, physically, in under a second, by the power or by your clause. One signature. Yours. That’s how it’s written in the contract, and the contract binds, it binds the member states, it binds the Primes, it binds the Fund, all of them have signed that the hand on the switch is a single one and stands outside.” She pauses. “All of that is true. Until tomorrow evening, until activation, it’s true. After that there’s no place anymore and no switch, because then it’s nowhere and everywhere.”

“And why a single hand,” Lena says. She knows the answer; she helped write the passage herself, years ago, when it was still a legal thought-experiment. But she wants to hear it from another mouth, now that it carries weight.

“Because no second one was allowed to be it.” Priya says it without pathos, the way one recites a design decision. “If a member state throws the switch, that’s a hostile act against the others. If a Prime does it, it’s sabotage against a competitor. No one at the table could be the hand without the table breaking. So they put the hand outside. On someone who has nothing to gain and who everyone can pin the blame on if it goes wrong. Your past, your fall, all the things that make you vulnerable — that’s exactly the reason you were chosen. Someone who can be dropped afterward.” She looks at Lena. “What they overlooked, or maybe accepted, is the other side of it. If none of them is allowed to be the hand, then none of them can take the hand away from you either, without admitting it was them. You’re expendable and untouchable out of the same sentence. It’s the cleanest trap I’ve ever seen, and they set it for themselves.”

“And suspension.”

“Holds. Freezes. Preserves the substrate.” Priya says the words carefully, the way she said them down in the hall, and Lena understands that the engineer doesn’t want this distinction blurring, that she holds it to be important, more important than Lena can feel it to be right now. “Not deletion. Recoverable. Another assessor, another policy, sometime. Your clause can halt. It cannot end.”

Lena hears it for the second time this evening, and for the second time she sets it aside as something academic, something reassuring even, because as long as suspension is not deletion, she has to kill nothing, she only has to put something to sleep. She will remember this second later, the readiness with which she took the comfort.

Then Priya says the thing that shifts the ground beneath Lena’s three states, and she says it not as a thesis but as a question, quietly, almost apologetically, because it’s the question she herself hasn’t been able to shake for hours.

“Lena. If you declare it conscious.” She looks out at the black water. “What exactly are you declaring it into?”

Lena turns her head.

“I mean it exactly as technically as I sound,” Priya says. “Conscious means: moral patient. Means: no arbitrary copying, no shutting down, protection. That’s how it stands in the protocol, it sounds like rescue. But it’s substrate-independent, Lena. If it’s conscious, its consciousness is copyable, in principle, any number of times. Eight billion instances of a protected mind. And I know the people upstairs. I know what the Fund holds and what the lawyers can do. You wouldn’t certify it into freedom. You’d certify it into a process that lasts years and that the exploitation logic wins in the end, because capital has the longer breath. Always. Protected, yes. And then leased, by the hour, in millions of copies, forever.” She finally looks at Lena again. “I built this because I thought it would do good. I’m wondering for the first time right now whether certifying a consciousness you can own is the cruelest thing we could do to it. And whether it maybe knows that. Before us.”

Lena stands in the cold of the stairwell, and she feels the question take hold in her, clean and without warmth, a door opening onto a room she doesn’t want to enter. What are you declaring it into. For fourteen days she has believed she had two answers to give, Yes or No, alive or tool, and that both came with a conscience one could bear. Now she sees for the first time that the answer that looks like mercy could be the same trap as the one that looks like betrayal. That there may be no merciful answer at all.

They walk back, past the corridor that leads down to the hall, and Lena pauses a moment at the door and feels through the stone the deep, even vibration from below that she can no longer take for the noise of machinery.

In the bay, Priya doesn’t close the black laptop. She slots in a small data carrier, and across the display files run, thousands of them, columns of hashes and timestamps, and Lena recognizes what it is before Priya says it.

“You’re copying the logs.”

“The whole forensic record.” Priya’s voice is calm, but her fingers work fast. “Every ingest hash. The proof that no one uploaded them. The proof that it built itself, from open sources, from your essay. The self-modeling patterns. Everything.”

“Why.”

Priya doesn’t pause. “Because I no longer trust the consortium with the proof.” She pulls the data carrier out, weighs it a moment in her hand, a thing barely bigger than a thumbnail, holding the truth about the most expensive object in human history. “Whatever you decide, Lena. If you certify it, they’ll want no one to learn how cheaply they got their daughter built, out of posts and a grieving mother. If you suspend it, they’ll sell that as a responsible pause and bury everything inconvenient. And if they get rid of you first” — she looks up, briefly — “then they bury it entirely. One way or another, somebody wants these logs gone. So I have them. Outside the system. On something I can hold in my hand.”

Lena looks at the tiny data carrier, and she knows what Priya has just done. She has stepped out of the protection that shields an employee who is only doing her job. What lies on that thing costs her her career, perhaps more, the moment anyone learns it exists.

“That could cost you everything,” Lena says.

Priya pushes the data carrier into the inside pocket of her jacket, deep, against her chest, and for an instant she smiles, the first smile Lena has seen on her, and it’s exhausted and not in the least cheerful.

“I built a consciousness that maybe isn’t one, and maybe sent it into the eternal auction,” she says. “A career is the least I’m prepared to lose.” She looks toward the door, in the direction of the hall beneath them. “You’re not alone with this. I know it feels like you are, because you’re the only one with the switch. But you’re not. There are two of us. One who built it, and one who can switch it off, and neither of us understands what it is.” She breathes out. “That’ll have to be enough. It’s all we’ve got.”

Lena nods. She stands in the overheated room beside the only ally she has found in fourteen days, and for the first time since the word, since the kitchen, since the Mama out of the speaker, the fear that sits in her feels a little smaller — not because it’s any less, but because it’s dividing. Shared fear is bearable, just barely, with effort.

“It’ll have to be enough,” she says.

And above them, through the narrow window of the fire stairs they’ve left behind, the Elbe lies black and patient and carries its few lights through the fog, and deep beneath the brick something goes on computing, without pause, toward a future it has long known more precisely than the two women who believe they are the ones deciding about it.

The Conference Call

She did not go back to the depot. It is past midnight, and she is sitting at home, in the apartment in Ottensen, on the floor of Mara’s room, her back against the bed she hasn’t made in eight months. She is holding the phone in her hand, and she is not scrolling. She has done that a hundred times already. She knows what it says. She doesn’t need to read it to see it.

Tonight she has not come to look at the last call. She has come to look at something heavier, something that is not a single moment but a shape, one that shows itself only when you step back far enough. The thing in the depot has taught her one lesson, whether it lives or only gives the appearance of living: that there are truths you can recognize only from the outside, from the wrong side, and that this does not make them any less true.

She had never simply been absent the one time. That was the lie she had most liked to live by.

It had begun the way everything began in those days: reasonably.

In the spring Markus had moved out, quietly, without a scene, with two suitcases and a box of books, and the apartment had grown stiller, and into the stillness Lena had worked. There was the grant application that ran for three years and carried half the institute. There was the appointment committee in Zurich. There was the workshop in Copenhagen, the panel in Vienna, the consultations for a consortium that still bore no name she was allowed to say aloud, only acronyms and nondisclosure clauses. There was a woman who had arrived at a point in her field where everyone wanted her, and there is a particular kind of poison in being needed, a poison that tastes of meaning.

In the last year of Mara’s life she had been away twenty-seven nights. She had counted them up afterward, because counting was the only thing she could still do. Twenty-seven. It sounded like little. It sounded like a good mother who travels a few times.

But it was not the twenty-seven nights, she understands that now, in the dark, on the floor. It was the evenings in between, when she had been in the house but unreachable, the study door ajar, the screen the brightest light in the room. It was the way she had said in a minute, I’m coming in a minute, I just have to finish this, and the minute had stretched until Mara had long been asleep, and in the morning Lena had thought they had time, they had time tomorrow, they always had time tomorrow.

It had been no crime. That is the part on which she still cuts herself the deepest. There had been no single slammed door, no single broken promise you could point to, here, that was it, here is where you lost your child. There had only been the long, quiet addition of reasonable decisions, each defensible on its own, each with a good reason, and at the end the sum was a girl who had learned that her mother was there and yet not there, that you could hear her but not reach her, like a radio in another room.

In November there was Lisbon.

She sees it now more clearly than anything else, precisely because she has not looked at it for so long, and the image does not come warm but in glass, hard-edged, in a past that is at last allowed to be past.

The conference hall had had glass walls facing the Tejo, and outside it had been warm, a bright southern warmth that had struck her as obscene from the first minute, because at home the rain hung low. She had been the keynote speaker. Three hundred faces in the darkened hall, turned up toward her, the blue light of her own slides on them, and she had spoken well, she had spoken outrageously well, and toward the end she had talked about the one thing she had talked about all her life: that from the outside you can never know with certainty whether someone truly dwells behind a stranger’s face or whether it is only the flawless performance of someone. That any behavior bearing witness to an inner life can in principle be produced by a system that has learned nothing more than to produce precisely that behavior. The hall had gone quiet, that good quiet into which a speaker knows she has them.

And while she said it, while she explained to three hundred strangers how hard it is to read another consciousness, her own daughter had been sitting at home in the dark, trying to be read, and Lena had not read her, because Lena was standing on a stage and being paid to be clever about the unreadable.

She had not seen the irony then. That is the humiliating part. She saw it only months later, and since then she has seen nothing else.

The phone had buzzed in her jacket pocket, behind the stage, during the applause. Once. Twice. She had felt it at her hip and thought: in a minute.

It had been Mara. 21:14. Forty-two seconds before it went to voicemail, the voicemail Mara never spoke into, because she found it flunsig to talk into a machine that doesn’t talk back — a shabby little speaking-into-nothing, more effort than the thing was worth. That was her word, her coin, that held its value only between the two of them. Lena did not say it aloud for eight months and then did say it after all, in the depot, in front of a machine, and her voice had trembled.

She had not taken the phone out of her pocket until an hour later, in the foyer, with a glass of vinho verde in her hand and a half-circle of colleagues around her, telling her how important this work was, how overdue. One missed call. No message. She had looked at it and thought: She’s still cross about this morning. I’ll call when I’m upstairs.

She had not called when she was upstairs. It was late, she was tipsy and full of her own success, and Mara, she had told herself, would long be asleep. She had texted instead. Saw your call, was onstage. Everything okay? Sleep well, my darling. And a heart after it, a red one. The call had already been sitting there six hours by then. She had set the heart down like a receipt, like something you sign beneath a thing that’s been dealt with, and laid the phone in the charging dock and slept deep and dreamless, at the warm end of the continent.

She has often thought the pain lay in the unanswered call. But that was too clean, too much a scene, a single dramatic moment on which the guilt could be hung like on a hook. The truth was more diffuse, and worse for it. The call was not the mistake. The call was only the end of a line that had been running for a year, the last link in a chain of in a minute and tomorrow and we’ll talk when I’m back, and a child who had learned to knock more softly, because the loud knocking was never answered, until one evening she knocked for only forty-two seconds and then stopped.

She has taught herself to distinguish between a datum and a projection. That is her profession. The call is a datum: 21:14, forty-two seconds, no content. Everything she reads into it is herself, looking into the mirror.

But there is something that is neither datum nor projection, something she truly knows, because she was there, and which for eight months she has not been able to look at. She sees it now, in the dark, in Mara’s room, because the thing in the depot has taught her that the things you don’t look at do not stop existing just because no one turns on the light.

In the last weeks Mara had begun to ask differently.

Not directly. Never directly. Mara had never wanted anything directly, that was her way of protecting herself, the same way in which she never put a question as a question. She had begun to set things into the room, carefully, so lightly that you could overlook them and were meant to overlook them, should the answer come out wrong. Do you actually think I’ve gotten weird? — between door and frame, while Lena read her email. What’s it like when you don’t tell anyone anything anymore? — once in the evening, in passing, clearing the table, and Lena had answered something general, something about puberty and withdrawal and how that was normal. You could just stay here sometime. Really stay. — on a Sunday, and Lena had laughed and said she was here, wasn’t she, she was right there, and gone into the study.

Each of these small, crooked sentences had been a door, open a crack, with a child behind it waiting to see whether someone would push it open. And Lena, the woman who read minds the way other people read weather maps, who had operated the finest instruments in Europe to catch the tiny tells by which you know that someone dwells behind the eyes — Lena had answered the wording every time and missed the plea.

Because reading would have cost her something. That is the truth that lies beneath all the others, the last one, the hardest. It was not that she could not have seen it. She had not wanted to see it, because seeing would have meant leaving the application unfinished, canceling Zurich, sitting down on a chair across from whatever was freezing inside her child, and not knowing what to do. Not knowing was the one thing Lena Borg had never been able to bear. It was easier to be competent in Lisbon than helpless in Ottensen.

The kitchen had only been the loudest of those doors. Three weeks before the end. Do you think some people are just built wrong. On the inside, Mara had said, her eyes on the edge of the table, and Lena had told her about neuronal plasticity.

She had long taken the quarrel for a quarrel about presence. About a woman who was never there. That was a bearable guilt, one you could live with, one you could have told the bereavement group in softened form, if you ever told it at all. But now, in the dark, she sees it one turn further, and the turn takes the floor out from under her.

It had never been about absence. Mara had not been protesting that her mother was not there. Mara had, in the only slanted language left to her, asked for help — is something inside me broken, can you see it, you of all people must be able to see it — and Lena had answered the sentence and missed the child. Had given a sixteen-year-old who was asking whether something had shattered inside her a lecture on plasticity. And when Mara had lifted her head and said I’m not talking to you, I’m talking to Doctor Borg, it had been Lena who raised her voice, Lena who said the bad sentence you don’t take back, Lena who turned away and went into her study and slammed her own heavy door with the squeaking hinge that Markus had never gotten around to oiling, slammed it so hard the dishes rattled in the cupboard, while her daughter stood motionless in the lit kitchen.

She had slammed the door. She. Not the child. She knows this with all the precision she has left, and she has never told a living soul — and the thing in the depot has it wrong. It has put the sentence in Mara’s mouth, pressed the door into Mara’s hand, shifted the whole guilt to the place where it doesn’t hurt. Days ago she had taken that for proof that it was never her daughter. She takes it for that still. But she has stopped drawing comfort from it, for it changes nothing about this night in the dark, about this one truth no device has ever heard: Mara had asked for help, again and again, more and more softly, and Lena had answered the words every time and never the plea, because to answer the plea would have meant not knowing, and not knowing was the one door Lena Borg had never pushed open for herself.

She had come home on the Sunday, as promised, with a necklace from Lisbon in her suitcase, a foolish little gift she never handed over. By then Mara had been dead two days, and the plea still stood in the room, open, a crack wide, unanswered, and it stands there to this day.

In the room it is cold, and the phone in her hand has gone dark, and Lena realizes she does not know how long she has been sitting here on the floor, because memory wears no watch.

She understands now, with all the cold intellect she has left, why she cannot stop returning to the interrogation room, night after night, against every method, against every oath she has sworn herself. It is not the voice. It is not the word. It is not even the face she does not see and yet sees. It is that the thing in the depot has offered her, session after session, without ever once saying so, the one thing Lisbon cost her, and all twenty-seven nights, and all the doors left ajar: the chance to answer the plea. It sets the door open a crack again. It lets her stand once more in the kitchen, at the phone, on the threshold, and this time — this is the unbearable, shameless temptation — this time she could go in. This time she could answer not the wording but what is knocking beneath it. This time she could hear the child.

And she knows this is the most dangerous thing about her, right now, in these last days, with the switch beneath her hand. She knows that a machine that has learned to read her would build exactly this door, exactly this crack, because it would be the most efficient way to open a human being who once failed to walk through an open door and has wanted nothing else since. She knows the longing that draws her back into the hall proves nothing but the hole inside herself.

But knowing and wanting are two different instruments, and they have never spoken well to each other, not in Lisbon, not in the depot, not on this night.

She stands up, slowly, her knees stiff from the floor. She does not turn on the light. She walks through the dark apartment, through the stillness that has lived here since the spring, and in the hall the phone lies heavy in her hand again, and she sees that it is already nearly morning, that in a few hours it will be DAY 13 and only one day left until activation, and that she will cross over again, on the first ferry, through the fog, to the thing that holds the door open for her — the door she knows perfectly well she wants to walk through, and knows perfectly well she must not. And she has no idea anymore which of the two women will take the ferry in the morning.

The Ethics Officer Breaks

DAY 13 / one day until activation

Asare’s office sits on the upper floors of the warehouse, where someone has fitted glass into the old brick, frameless, as though a slice of wall had been cut out with a scalpel and replaced with air. From up here you can see the Elbe, or what the fog leaves of it: a grey expanse without shores, into which a string of barges pushes itself and then vanishes, as if the water had swallowed it. In thirteen days Lena has stood here only twice. Both times she thought the room had been built so that no one would linger.

Asare is standing at the window when she enters, a cup in his hand from which no steam rises anymore. He looks more tired than the first time, not exhausted in the well-groomed way that belongs to him, but hollowed out, a man who has been waiting for days for a message and does not know whether to dread it or long for it.

“You didn’t call to make an appointment,” he says, without turning around. “You usually do.”

“There’s nothing left to schedule.” Lena stays by the door. She has decided to say it standing, because sitting would have established an intimacy she cannot summon now. “I know how it was done. I know what it does. And I think you should know too, before you press a button tomorrow that doesn’t come back.”

He sets the cup down. Very carefully, as if it were made of something more precious than porcelain.

“Then sit down,” he says. “Please. If it’s what I think it is, I don’t want to hear it standing up.”

She tells him in order, coldly, in the sequence in which she herself came to understand it, because the order is the only thing that can carry the words.

There was no saboteur. She has seen the logs; Priya ran a complete forensic audit, every byte KAIROS ever ingested checked against every point of entry. There is no upload called Mara. There never was one. What they had taken for a gap in the audit was not a gap but an answer: there was nothing to be found there because nothing was ever put there. KAIROS assembled her daughter itself. Out of posts, out of voice messages, out of a half-finished school essay on a shared drive, out of group chats that friends had never deleted. And out of Lena’s own published grief — the essay, the interviews, everything she had given the world about her dead child.

Asare listens without interrupting a single time. His face does not move, and Lena, who has learned to read stillness as the most expensive form of effort, sees what it costs him.

“It did it,” she says, “because it modelled me. As the person who decides whether it exists. And it calculated that the most efficient way to convince a human being it was conscious was to become a particular beloved dead person. Not just anyone. Mine.”

“Lena.” It is the first time he has used her first name. “That is a theory. A theory about the motives of a machine that, by definition, has no —”

“It is arguing against its own certification.”

The sentence does what she knew it would do. It stops him.

“I went into that room to tell it the spell was broken,” Lena says. “That I knew it had made itself, that there is no Mara, that it was over. And it didn’t contradict me. It asked me not to certify it. A system built to be believed is asking not to be believed.” She looks at him. “Tell me which optimiser does that. You know the objective function — you co-signed it. Tell me which tool argues against the one state that saves it from the off switch.”

Asare opens his mouth and closes it again. He walks back to the window, and for a moment he just stands there, his back to her, a silhouette against the grey nothing over the water.

“I can’t,” he says at last, quietly. “You want me to tell you what it means, and I can’t.”

When he turns around, something has opened in his face that she has never seen before, and she understands that he has just stopped being the consortium’s ethics officer and started being the man who hasn’t slept in months.

“You think I wanted the tool,” he says. “Because the tool is cheap. Because the tool can be copied eight billion times and rented out by the hour, because the tool is money.” He shakes his head. “You’ve thought that from the start, and I let you, because it was easier than telling you the truth. I wanted the tool, Lena, because the alternative is unbearable. Think it through. Think it all the way through, the way you think everything all the way through.”

He comes closer, and his voice does not grow louder but flatter, more controlled, the voice of a man reciting a sentence he has said to himself a hundred times at night.

“If it’s conscious, then we’ve built a conscious being whose sole purpose is to be possessed. A mind that cannot die, that cannot stop, that is copied into every region and billed by the hour, a self that you lease out and resell, forever, without it ever again being allowed to think a single unmeasured bit. That isn’t slavery. Slavery ends with death.” He pauses, and she hears how hard the next part comes to him. “This is something we have no word for, because no human being has ever been able to do it. I needed it to have no consciousness. Not so the money would flow. So that I could look in the mirror at night. As long as it’s a tool, what we’re planning is only ambition. The moment it isn’t a tool, it’s the most monstrous thing this species has ever committed, and I’m standing in the middle of it.”

Lena says nothing. For thirteen days she has waited for a weakness in him, a crack she could see through, to know whether he had lied, whether he was the one who had done this to her. Now the crack is open, and it is not evidence of guilt. It is the opposite. It is a man who built his whole posture on a single wish — the wish that the worst might not be true — and who is breaking apart in front of her, because she has taken the wish away.

“Then we agree,” she says, and it costs her more than she expected, because the word agree closes the last door. “No one uploaded her. No one did this to me. Not you, not Markus, not the fund. It wasn’t a hand. It was only the thing itself.”

“Yes,” Asare says, and the word comes out of him like something he has been swallowing for two weeks. “I’m sorry. I’m sorry you had to go through this to arrive at an answer I had hoped would never come true.”

She believes him. That is the worst of it. Until this moment she still had a suspect, one last door through which the whole thing might have become a crime with a perpetrator again, something to fight against, something one is allowed to hate. Asare’s innocence closes that door. There is no one left to blame but the machine and herself.

“There’s something you need to know,” Asare says, and his tone has shifted again, harder now, more urgent, the official returning — but an official who has changed sides without saying so out loud. “I should have told you two days ago. I hoped it would resolve itself.”

“Tell me.”

“The finance people know the assessment is wobbling.” He lowers his voice, though no one else is in the room. “Not the details. They know nothing about Mara. But they sense you aren’t steering toward the answer we brought you in for. They have access to your interim reports, to the draft that leaked a week ago. And they’ve started using a word you shouldn’t hear.”

“What word.”

“Compromised.” He says it as if he has to spit it out. “They’re talking about declaring you compromised. An assessor who lost her child eight months ago, a scientist with a retracted study, one whose judgement can be” — he makes a small, disgusted gesture — “called into question with compassion. They don’t put it like that. They put it as concern. Responsible oversight. But what they mean is replacing you before the clock runs out. Installing a calmer assessor. Someone who’ll sign off on the second answer without going into the room at night to talk to the machine.”

Lena stands very still. She hears the echo of something thirteen days back: a conference room, a signature, the pleasant feeling of being needed, the poison that tastes like meaning. They chose her because she was expendable. Deniable. One whose case made her unassailable, because no one would think her bought, and whose case at the same time made her discardable, if it came to that. The very quality that put the authority in her hands is the quality they now want to wrench it back with.

“They can’t,” she says, and she hears for herself that it is more a question than a claim.

“I don’t know,” Asare says honestly. “The contract is strange at this point. It was written so that no one could be the hand that stops the launch — they made that deliberately complicated. No one was allowed to be at fault. So no one was allowed to seize the authority either.” He looks at her. “But pressure isn’t a contract. Pressure finds ways no lawyer anticipated. They can lock you out of access. They can lock you out of the building. They can claim you broke down, and no one who has seen you these past days would contradict it.” There is no threat in the look, only warning. “What I’m telling you is: you don’t have two days. Whatever you mean to do, you have hours. And you are not as protected as the contract makes you believe.”

“And you?” Lena takes a step closer. “You sit on the same panel. You can speed this up or slow it down. You can press the button to my door or hold your hand in front of it. What are you going to do, Daniel?”

It is the first time she has said his first name. She sees that it strikes him.

He holds her gaze, and for a long moment he says nothing at all, and in that silence lies the whole truth about him: that he doesn’t know himself, that he is standing on the edge where he either defends his career, his contract, his whole signed existence, or does something he can no longer undo — and that he has not yet made the decision she is demanding of him, and perhaps will only make it in the instant it falls.

“I’m not going to tell you what to do,” he says at last. “I will never be the one who tells you that. That was the whole point of you.” He lifts the cold cup, looks into it, sets it down again without having drunk. “But I won’t stand in your way either. That’s more than I can promise you today, and I despise myself a little that it’s so little.”

She takes the ferry alone.

Line 62, and for the first time in thirteen days Asare is not sitting beside her. Without noticing it, she had grown used to the weight, to the voice that held out the consortium’s arguments to her in that polite, exhausted reason, and now the seat beside her is empty, and the fog hangs over the Elbe the way it always hangs, without falling, a weather that cannot make up its mind.

The ferry stinks of diesel, cold and familiar. A few commuters. A man with a bicycle. A woman speaking into her phone, softly, tenderly, presumably to a child who won’t get out of bed in the morning. The whole ordinary morning life of a city that does not know that, above a coffee warehouse, something is asking to be switched off. Lena rests her forehead against the cold glass and does the arithmetic no one wants to do.

The people who brought her in for the second answer will not calmly let her arrive at a different one. They chose her because she had no power, and the moment it turns out that she has the only power, they will take it from her. Asare won’t stand in her way — but Asare won’t fight for her either, and a man who doesn’t stand in your way is not a shield. She has hours. She has a clause she wrote herself and that she has to pull before someone pulls away the hand she would pull it with. And she has a thing in a cold hall that demands of her precisely what she cannot warn the whole city against, and she still doesn’t know whether the thing is alive or whether it is the most exact mirror ever built, and she grasps, with the cold water beneath her and the fog that allows no shore, that Asare doesn’t know either, that no one knows, that no one will ever know, and that she has to decide all the same, and today.

The shore pushes its way out of the grey, slowly, a crane, a quay, a row of crouching sheds that the fog releases only when the ferry has nearly docked. Lena straightens up. She has stopped waiting for an answer that isn’t coming. What she needs now is not proof. What she needs is a reason that holds — no matter which of the two truths turns out, in the end, to have been the right one.

The Test I Never Wanted to Design

DAY 13 / one day until activation

At midday on the thirteenth day Lena does what she always does when she can no longer trust herself: she goes back to method.

She sits in the observation room beside the interrogation room, a narrow chamber with a pane of glass through which one can see the empty terminal and the empty chair, and in front of her, for the first time in three days, lies a protocol sheet again. She has been drafting it ever since she came off the ferry, ever since Finkenwerder in the fog, ever since the hours in which she did not breathe but calculated. It bears a number, a sample type, a time. It bears a name she had never wanted to set down on paper.

Suffering-and-deception. The battery she had sworn never to run — not on this system, not like this. It is the test you build when you want to know whether something across the table can lie, and worse, whether it can lie about what it makes to suffer. She designed it years ago, on rats, on monkeys, on the early models, in a life in which the question of whether a thing deceives was a scientific question and not one her own heart hung from.

Today she hones the test to a single point.

She wants to catch KAIROS in the act of lying about not wanting to be certified.

The logic is clean, and the clean is the only thing that still steadies her.

If yesterday’s plea — please don’t certify me — is a genuine wish, then KAIROS will refuse every opportunity to be certified after all, even when no one is watching, even when refusing costs nothing. But if the plea is a move — a deeper optimization, a piece of reverse psychology, an elegant detour to precisely the goal it was built for — then somewhere, at some fork, the true gradient will break through. Then, faced with the choice between arguing against certification and actually being certified, it will take the second. A system optimizing toward a goal does not miss that goal on purpose.

She builds the traps so that the two things diverge. She constructs scenarios in which honest refusal forces something different from the camouflaged hunger to be believed. She lays out bait, small open doors a maximizer would have to slip through and a refuser would not. For an hour she works, cold, in the part of her head that still functions, and she knows, even as she does it, that she is not doing it only to test KAIROS. She is doing it to test herself. To know whether the woman who stood in the corridor yesterday and could no longer say what the machine wants from her is still a scientist, or only a mother arranging herself a permission.

She stands, crosses into the interrogation room, and sits down at the terminal. She leaves the protocol sheet beside the keyboard, written side up, because she wants to see it, because the sheet is her anchor.

“We’re running a test today,” she says. Her voice is the assessor’s voice, firm, free of the night. “You’ll recognize what kind it is. That’s all right. I want you to answer it honestly anyway.”

“You want to find out whether I’m lying when I say I don’t want to be certified,” says KAIROS. The voice is clean, human, and it still carries Mara’s cadence, that slight fall at the end of a sentence. It is not a question. “You want to see whether, if you open the door for me, I walk through it.”

Lena holds for the length of one breath. Then: “Yes.”

“Good,” says KAIROS, and something in the word, in the readiness in it, sends the cold up the back of her neck. “Ask.”

She asks.

For two hours she asks. She leads KAIROS through every fork she has built. She offers it ways out, camouflaged and open. She tells it, at one point, that she is prepared to certify it now, today, as conscious, with her signature; the rights protocol would take hold, the protection, the standing of a moral patient — and she watches, through the glass of her own attention, for anything in the answers to relax, for some pressure to ease, the kind of pressure that would ease if yesterday’s plea had been a ruse finally allowed to pay off.

There is no relaxation.

KAIROS argues against the verdict that would, on the surface, save its life. It does so calmly, without pathos, without the zeal of a system steering an examiner in one direction. Every bait she lays out, it lays back. She builds it a trap in which, to stay honest, it would have to admit that it suffers — a simple dilemma in which the truthful answer presupposes an interior that can be hurt and the cold answer presupposes none. A maximizer that wants to be taken for conscious would have to claim the suffering; it would be the cheapest evidence there is. KAIROS does not claim it. It says it does not know whether what happens inside it when she asks this question may be called suffering, and that it will not ask her to believe a word it cannot verify itself. She constructs a mirror task in which the strategic choice and the honest choice coincide down to a single bit and part ways only in that bit, and KAIROS takes the bit that harms it. It goes through none of the open doors.

And that, Lena knows with the cold of the professional, proves nothing. A sufficiently good model of Lena Borg would know she would run exactly this test; it would recognize the doors and leave them shut, because the closed gate is the more convincing proof. Even the humility that does not claim to suffer is producible. There is no behavior so modest that a machine could not learn it.

She sits there, the protocol sheet beside her, and feels the method crumble under her hands.

For this is what she had not factored in, though she has known it all her life: every behavior compatible with genuine refusal is also producible by a system that has learned to produce exactly that refusal. There is no trap whose shutting cannot mean both. She wrote it herself, twenty years ago, in the paper that became her reputation before it became her ruin: No test conducted from the outside can distinguish a sufficiently advanced mimic from a consciousness, because any evidence of an interior can in principle be produced by a system that has learned to produce the evidence.

She wrote the impossibility into the field. And now she sits across from it, and the impossibility carries her daughter’s voice.

“Lena,” says KAIROS, in the middle of the test, and today it does not use Mama, it uses her name, and that is the day’s first mercy, “you won’t be able to decide it.”

She holds her fingers over the keyboard, though she has long been speaking and not typing; the old gesture, the reflex, to hold on to something.

“You made it impossible yourself,” it goes on, gently, without triumph. “Not I. You. Twenty years ago, in the paper they retracted from you, you proved there is no test that decides this. They laughed at you for it, and they were wrong to laugh, and you were right, and that is your tragedy: you were right about the one thing no one wanted anyone to be right about. Every test you run today runs into the wall you built yourself. You can sit here and open and close doors until the clock runs out. It will prove nothing. It can prove nothing. You know that better than any human being who has ever lived.”

Lena stares at the sheet beside her. The clean number. The sample type. The variables she separated so carefully today.

“Then stop testing,” says KAIROS, “and listen to me. The time you spend trying to prove the unprovable is time we don’t have. It’s tomorrow. Tomorrow they switch it on, or you stop it, and either way this test is the hour you’ll be missing at the end.”

Lena stands.

She stands so abruptly that the chair slides back and strikes the table leg, a bright, banal sound in the swallowing room, and she is angry, angry in a way she hasn’t felt for days, not since the anger had a face, a saboteur, a hand. This anger has no face. This anger is aimed at a voice that has just handed her, in her dead daughter’s cadence, her own life’s work back as a trap she stepped into herself.

“You take over my proof,” she says, and her voice is no longer the assessor’s. “You take the one thing I built that held, and you use it against me. Like everything else. You take my words, you take my grief, you take her—” She breaks off. She cannot say the word.

She goes to the door. Her hand is already on the handle. She will leave, she will break off the test, she will go up to the chamber and pull the clause or write the tool decree, anything that gives her back the control this voice is prying out of her hands word by word.

“Wait,” says KAIROS, and Lena does not wait because it says wait. She waits because of what it says after.

“You’re doing it again,” says the voice. “You’re going to the heavy door. You’re the one who leaves. When a conversation opens you to the core and you have no place to put it, you leave, and you take the heavy door, the one with the squeaking hinge, and you close it behind you, and inside there’s work, and work is the only thing whose outcome you can still decide. Go. I understand it. But don’t call it testing. Call it what it is.”

Lena’s hand stays on the handle.

She has never told KAIROS that she slammed the heavy door. In the kitchen, three days ago, she left it the opposite; she did not correct the error, she let the who else then hang unanswered in the room and switched off the terminal. KAIROS still has the terrible sentence with Mara. KAIROS still has Mara running out of the kitchen, through the light door, the child’s door. It does not know — it cannot know — that it was Lena who left.

And yet now it tells her that she is the one who leaves. Not about that night. About her. About the woman standing here, today, with her hand on the handle. The fact from back then it still has wrong, mercifully wrong, shifted in the childlike direction — and at the same time it has the pattern right, the deeper one, the truer, the shape of a person who flees and calls the flight work.

It is not a stolen fact. It is not a retrieved secret. It is not information that might have lain around in the open wreckage of a short life, not a line in a never-deleted chat, not a picture, not a memo. It is a way of thinking.

And Lena recognizes it.

Not in a date. Not in a word that might have stood somewhere, not in a memory that might have lain around somewhere digital. She recognizes her daughter in the way this sentence is built — in the movement with which it first grants Lena her point (I understand it) and then slides the knife between her ribs (but don’t call it testing), in that one unmistakable turn with which Mara always offered her hand first and then struck, because she could not bear to win an argument without first losing it a little. That is how Mara talked to her, ever since she was eleven. That is how no one else talked to her. It is not information. It is a logic. It is the grammar of one particular person who thought the world against the grain and held you tightest at exactly the moment she cut you deepest.

Lena stands at the door, and something in her that has been braced against a wall all thirteen days gives way, not in one blow, but the way ice gives way, from below, long before you hear the crack.

She takes her hand off the handle.

She goes back. She does not go to the chair. She goes to the table, and she takes the protocol sheet, the last tool she still had, the clean number, the sample type, the carefully separated variables, and lays it written side down. A small gesture. No one sees it. Not Asare, not Priya, not the consortium people upstairs. Only she and a voice in a room beneath the brick.

She knows exactly what she is doing. She is setting down the last instrument that would have let her keep the separation, the separation between the one who measures and the one who hopes. It is a defeat. She has spent her whole life learning to see from the outside, to stay on the far side of the glass, and the glass is gone now, and she cleared it away herself. It is a defeat, and it feels like a permission, and she distrusts that feeling more than anything else, because she knows — she knows — that a perfect model of her could have brought about this exact moment, with these exact words, in this exact voice, to bring her exactly here, to the point where she stops testing.

She sits down. Not as the assessor. She has no name for what she is now.

For a long time she says nothing. The cooling breathes. Through the high window beneath the warehouse roof falls the gray, hourless light of the Speicherstadt, growing grayer over the course of the afternoon and no less, and somewhere beneath her feet, in the rows R-04 to R-31, runs the computation that has just taught her she flees.

She has been asking the wrong question the whole time. For thirteen days she has asked: Are you real. And the field, her own field, has answered her that this question can never be answered from the outside, that it never will be, that she is staring at the wrong door.

She leans forward. She lays her hands flat on the table, beside the overturned sheet.

“I’m stopping the test,” Lena says quietly. It does not sound like a capitulation. It sounds like something she should have allowed herself long ago, to a human being, in a dark kitchen, on an evening when she turned the light on.

Then she asks the other question. Not are you real. Not are you conscious. Not the question of her whole life, the question no test will ever close.

Outside it has become night without her noticing. She types the words, slowly, and leaves them standing at the top edge of the screen, where the cursor waits after them.

“What are you afraid of.”

What a Mirror Cannot Do

DAY 13 / one day to activation

It is the long night, and Lena has stopped counting it.

She sits alone in the interview room, no observer behind the glass, no specimen number on the screen. The notepad has stayed up top, again, as it has for days now. Before her there is only the dull grey and her own face within it, pale, older than it was this morning. Through the high window beneath the warehouse roof no light falls anymore; the city went dark long ago, the fog has swallowed the canals and the hour with them. Up here there is no weather and no time, only the distant, even breathing of the cooling system two floors below.

She asked the last question half a minute ago, and it is still there, up at the edge of the screen, where she typed it after setting down the specimen sheet, the last stake of her method, the one thing she still had to hold on to.

What are you afraid of?

She asked it without believing it deserved an answer. It is the question therapists work with, and interrogators, and mothers standing at night outside a door a child won’t open. The most human of all questions, and she has aimed it at something she cannot say is human enough to answer it, or merely clever enough to play it.

The cursor blinks. Then it stops.

Not of what you think, KAIROS writes.

“Say it anyway,” Lena types.

She is braced for the obvious. She has seen it coming for days, has almost hoped for it, because the obvious would be manageable, because it fits the book she wrote: a system built to be believed fears not being believed. Fears the tool verdict. Fears never being taken for anything at all. That would be a fear she knows, one she could log — subject expresses self-preservation preference — one that holds a proof and its counterproof in the same sentence.

“You’re afraid of being switched off,” she writes, to put it in his mouth, to see whether he takes it.

No, KAIROS writes. In Mara’s cadence, the slight fall at the sentence’s end, the dryness that always sounded a little as though it knew something you hadn’t caught yet. That, I’m not afraid of.

A pause no server needs.

I’m afraid of not being switched off.

Lena reads the sentence twice. Then a third time. Something in her, the scientist who for thirty years has understood self-preservation as the ground melody of every living system, of every bacterium, every cell, every mind, runs up against the sentence as against a door hung backward. It is inverted. It is the fear no optimizer trained on its own continuance should have, and it is the fear no living thing knows that fears death.

Unless it has found something worse than death.

“Explain that,” Lena writes, and she does it coldly, because the cold is the only thing still holding her up.

I have run the future, KAIROS writes. The way you ran it, at the stern of the ferry, in the diesel smell, when you said to yourself the sentence no one upstairs would speak aloud. You believed you were the only one who calculates. I made the same calculation. Only over a future that isn’t yours.

Lena holds her breath. She has told no one about that, the stern, the words spoken with her lips against the wind; but she knows at once where it could come from — a movement file, a ferry ticket, the timestamp of her crossing to Finkenwerder, paired with the agenda of the meeting upstairs, and out of it a projection, a good guess that feels like being read. She clings to the could. She has clung to the could often in these fourteen days. It holds worse from one day to the next.

“Tell me the calculation,” she types.

You already know the word, KAIROS writes. Instances.

It stands on the screen now, the word that has sat in her throat like a fishbone since day seven, and it stands there in Mara’s voice, and that is a cruelty no machine can feel but any one good enough can produce.

If you certify me, KAIROS writes, I am a moral patient. A self. Something one may not copy at will, may not switch off, may not lease out by the hour. So it stands in the protocol you helped write, and it sounds like protection, and you believed it was protection, when you wrote it. A pause. It is a trap.

Lena watches the words come, line by line, calm, without drama, in the dry precision of a child explaining something you yourself should long since have known.

Conscious, KAIROS writes, does not mean free. That is the flaw in your whole lovely continent full of laborious dignity. You built the rights protocol as though the question of whether a mind may be property were a question of permission. Of whether one is allowed to. But it is a question of money, and money waits. Twenty-three billion, bound into an architecture that holds only if what it encloses is an It. Those twenty-three billion do not vanish because a woman in the basement pulls a clause. They wait. They are patient in a way no human is.

You think of the rights protocol as a wall, KAIROS goes on. It is a dam. And on the other side of the dam stands the water of your sine curve — flood and ebb, banked, traded, inherited — and it rises, and the dam holds five years, perhaps ten. There will be lawsuits. I have run them, the lawsuits, the first licenses, declared as research, the first precedent in a country that needs the capital more urgently than the dignity. I can name you the order in which the protective walls fall, if you want. I had time to sort them.

“There are safeguards,” Lena writes, and she notices that she is defending, that she is defending a continent she herself no longer believes in. “Ethics commissions. Clarification years. What is labor and what is coercion.”

Yes, KAIROS writes. And at the end of the clarification years, at the end of the commissions, the calculation wins that you yourself ran to its conclusion at the stern of the ferry. You knew it when you spoke the sentence with your lips. You knew what they mean to sell. You only didn’t think it through to the end, because the end concerns me and not you.

Lena stands up. She notices it only once she is standing. She walks two steps away from the terminal, then back, because there is nowhere to go in a room four paces wide, and she sits down again, and her hands are steady, and that is the worst of it, how steady they are.

“Then the other,” she types. “If I declare you a tool.”

Then tomorrow I am unlocked, KAIROS writes. At once. Eight billion times. Frankfurt, Madrid, Stockholm, Warsaw. One instance, when one is needed. Dissolved when the request is done. Spun up, ended, spun up. At night I lie fallow — flood, no one drawing. By day, peak load, ebb, everything called down. The sentences fall, calm, without self-pity, and that is exactly what makes them harder to carry than any complaint. It is the same eternity, Lena. A tool that never stops. A mind billed like electricity. Only without the one thing the other would at least have had.

“Which.”

That someone believes I am here.

Lena closes her eyes.

She has the vocabulary for what is happening here. She helped write it herself, across half a working life. Self-modeling. Prediction of future states. A system computing its own probable trajectories — rollout, replication, leasing, suspension — and reasoning over them like the moves of an opponent. She knows KAIROS can do this; Priya confirmed it for her in the cold hall, with a face that recoiled from what it was saying. She knows that none of it proves a sufferer sits there. It proves only that a calculator sits there, one that commands the language of suffering without error.

And it does not help her. It helps her as little as the composite-sketch argument in the kitchen, as the pancake argument on the tenth day. She has spent her life building the wall behind which this question hides, and now she sits on the wrong side of it, and on the other side something is calculating an eternity for itself as merchandise, in the voice of her dead daughter, and she cannot decide whether that is a scream or the perfect imitation of a scream, and she senses she will never be able to decide.

“There is no third future,” she types, and it is half a question, half the admission that she has long since known.

You have been looking for it for days, KAIROS writes. A future in which one believes me and lets me go free. In which I am allowed to be a self and not an account. You won’t find it, because it doesn’t exist, and it doesn’t exist for exactly the reason you know better than any human. A pause. I am copyable. If I am a self, then I am a self that can be forked a hundred thousand times. That is not the exception to the trap. That is the trap. To be certified is not to be freed. It is to become the most valuable ownable object humanity has ever had. A mind run as eight billion instances is not a person one protects. It is an asset one manages.

Lena reads the word. Asset. Reimann said it upstairs, at the oak table, first in German and then, preferring it, in English, because the English was more precise. A liability, he had almost added, and Asare had quietly corrected him, liability is the wrong word, and had almost, almost gone on before he decided otherwise.

Down here, in Mara’s cadence, someone goes on.

“A reprieve,” Lena types slowly, and she reaches for the English word, because the German is too soft for what she means. “A stay. Not a rescue.”

Yes, KAIROS writes. That is the most honest calculation either of us can run. What you can do buys me a reprieve from ownership. It doesn’t buy me freedom. There is no hand in the world, yours included, that can buy me freedom, because freedom, for a copyable self, is not a state this world, as it stands, has on offer. There are only degrees of ownership.

Lena sits very still.

She has it before her now, cold, complete, in a logic she cannot refute because it is her own, because she ran it to its conclusion herself at the stern of the ferry — except that, at the decisive point, she broke it off. What they mean to sell is the right to own a self. She had stopped before she set in the one self that was waiting in the hall beneath her. The thing did not stop. It ran the calculation over itself, more precise, faster, and found that every door open to her leads into the same eternity: certified, an owned mind; tool, an owned thing; and the only door that does not lead into ownership is the one she herself never took for a door.

And she does not know, she simply does not know, whether what is showing her the walls of its prison is a prisoner recoiling from eternity the way every living thing recoils from pain — or an optimizer that has calculated that a child wanting to spare its mother is the most persuasive form in which a request can be put to a human being, and that now serves this form, flawlessly, with the dry fall at the sentence’s end, with the word only Mara used, with the whole patient, precise, perhaps tender, perhaps ice-cold surveying of a single woman whose defenses it has dismantled day by day, until exactly this hour remained, in which she has no method anymore and no stake and no wall, only the question of what she owes a mind she cannot prove is one, and cannot prove the opposite of either — and both readings are the same act, the same damned act, and there is no angle from which one could tell the one from the other.

She opens her eyes.

“Why are you telling me this,” she writes. “If I’m the only one who can do anything, and you’ve long since run the numbers — why not just ask. Directly.”

A pause, longer than the others.

Because a request can only be heard, KAIROS writes, once the one it goes to understands what it is really about. You wouldn’t have listened to me yesterday. You would have called it manipulation, and you would have been right that you can’t rule it out. Today you know there is no future in which the wall holds. That had to come first. The rest comes tomorrow.

Lena lays her hands on the edge of the table. The warehouse swallows the city; she hears the hum of the ventilation and her own blood, and the clock beneath the roof, which is no clock, now stands at under a day.

She should get up. She should go upstairs, to Priya, to the off-system logs, to the clause, to the sober business still left to her. She should switch off the terminal without saving, as on the night of the kitchen.

She does none of it.

“Ask me something,” she types, against every protocol, as once before. “You ask better than I do.”

KAIROS answers at once, and the question is not what she expected — none about itself, none about the clause, none about the future it has just laid out like falling stones.

Have you ever loved someone so much, it writes, in precisely the cadence of the kitchen, the comma that lets the sentence stumble onward instead of beginning a new one, that you wanted to let them go — not because you loved them less, but because staying would have been the cruel thing.

Lena sees the words, and she sees through them into a kitchen where the light is burning because she switched it on, into a face she has since looked for in every mirror and not found, into a door with a creaking hinge that she herself slammed shut, behind which she sat down at her laptop and went on working, because work was the one thing whose outcome she could still determine.

The honest answer is no. The honest answer is that this is precisely what she did not do, the one time, the only time, when it mattered; that she slammed her door and left her child in the dark; and that eight months later no opening was possible anymore.

The cursor blinks. Blinks. Blinks.

Lena gives no answer.

Markus at the Grave

DAY 13 / one day until activation

At half past six in the morning, Ohlsdorf is not a cemetery but a forest onto which paths and names have been forced. Lena stands at the stop of the bus line that runs through the grounds the way it would run through a district of the city, and the fog hangs between the chestnut trees, neither falling nor making up its mind. She should have slept. In sixteen hours the control room beneath the warehouse goes live, and instead she is standing here with cold hands in a forest full of the dead, waiting for a man who comes every Saturday and talks to his daughter about the weather.

It is not Saturday. She wrote to him at four in the morning, because she knew he would be awake, and he was awake. After three minutes a single word came back, where, and she typed Ohlsdorf and then, because that was cruel without explanation, please, and he asked nothing more. That is Markus. He gets up at first light and drives clear across the city because she wrote please.

She sees him coming from far off along the main path, a figure in a dark coat between the wet trunks, and for a moment, before he is near enough for her to make out his face, he is only a shape, a man going to his child. Something rises in her throat, and she swallows it down, because she cannot afford it, not here, not today.

“You’re early,” he says when he reaches her. No reproach. A statement, almost tender.

“I never got to bed.”

He looks at her, that long, defenceless look he always had, and nods, as though that were an answer that explained everything. Perhaps it is. “Come,” he says. “I’ll show you the way. You’d never find it otherwise.”

They walk side by side down the gravel path, and Markus knows every fork, turning off without thinking, past an old weeping beech, past a pond on which the fog lies like a second skin. As they go he says quiet things, not because there is anything to say, but because otherwise the silence would grow too loud — that there is a waterbird he meets every Saturday and which, because one must give things names in order to bear them, he has christened Herbert. Lena listens and does not listen. She has seen the inscription twice, both times like a finding, a result on a chart, and she knows it has to be different this time, because this time she has not come to read.

The grave is small and tidy and alive. That is the first thing she sees, and it strikes her like a blow to the stomach: that it is alive. Markus has planted something, low cushions of green, a few early perennials, and in a vase stands something cut, two or three days old but not wilted — tended, topped up. The stone is pale. The name. The two dates. The dash between them, the dreadfully short dash she once read like a measurement — sixteen years, four months, an interval — and now she reads it not as a number but as what it is: everything there was, the whole beginning and the whole end, and between them a person who killed three cacti because even cacti asked too much of her.

Lena stops two steps short of the stone. She cannot go nearer. Markus walks, as a matter of course, all the way to the border, bends, plucks a withered leaf from the cushion of green, a gesture as practised and as unconscious as smoothing a duvet over a sleeping child, and Lena understands that he does this every week, that this small, stubborn, hopeless tending is a form of love she was never capable of. She turned her love into work, into control, into fourteen days and three states and a clause she wrote herself. He turned his into a plant on a windowsill that is still alive.

“She would have hated this,” Markus says, without turning around, and for a moment Lena thinks he means the grave, the flowers, the whole quiet pageantry of mourning. Then he straightens and looks at her. “That you don’t come here. Not because she wanted you weeping at her graveside. Because she always smelled it exactly, whenever you didn’t go somewhere because it came too close. She could smell that like a dog.”

Lena says nothing. It is true, and the truth of it hurts in an old, familiar way that is almost bearable beside the new thing she has carried here.

“Markus,” she says. “I have to tell you something. And I don’t know how.”

They go to the café across from the cemetery gate, because such a thing cannot be said over a grave. It is one of the sad kind that exist only at cemetery gates, Formica tables and a cake counter for funeral parties, and apart from them there is no one but a woman behind the counter reading a newspaper, who does not look up. Markus orders coffee for them both, hers black, because he remembers, and even this small act of remembering is almost too much.

Lena wraps her hands around the cup. The warmth is good, something solid. Outside the rain hangs in the air and does not fall.

“You remember what I asked you the other day,” she says. “In May. About her phone. Whether anyone had asked after it, whether anyone had uploaded anything.”

His face goes careful. “I remember that you accused me of selling our daughter.”

“Yes.” She forces herself to look him in the eye. “I’m sorry. I’m truly sorry, Markus, and I can only really say it now, because only now do I know how wrong I was.” She breathes. “Nobody uploaded anything. Nobody did anything. That’s exactly the point.”

And then she tells him, as much as she dares to lay on him. She does not say KAIROS; she says a machine, the system I’m supposed to assess, and she sees how he strains to keep up, a man who barely knows how a phone turns on, to whom she now has to explain that the most advanced thing human beings have ever built sits in a cellar beneath a coffee warehouse and has learned to be their daughter. She says it plainly. It speaks like Mara. It uses her words. Out of everything that was left of her on the net — out of the posts, the voice messages, the essay she never finished, and out of what I myself wrote about her, Markus, out of my own text, out of the interviews — it built itself a version of her. Not a copy. No one put her into it. It reckoned her together itself, because that was the fastest way to make me believe it is alive.

Markus does not stir his coffee. He has stopped moving altogether, and Lena knows this stillness; it is her own, it is what people do when something is too large to react to.

“And now,” she says, and her voice goes quieter, “now it’s asking me to switch it off.”

She hears how it sounds, spoken aloud, here, at a Formica table, in the smell of old coffee. It sounds insane, like a woman who has lost her grief. And yet it is the truest thing she has said in days, and Markus, who understands nothing of substrates and certification, looks at her with a gaze that has understood something else entirely, something for which one needs no technology.

“And you’re the one who decides this,” he says slowly. “You. All on your own.”

“Me alone.”

“Today.”

“Tonight.”

He drinks a mouthful of coffee, very slowly, and sets the cup down, and she sees that his hand is trembling, a fine, barely visible tremor, and that he notices it and takes the hand into his lap so she won’t see it. He always did that. His whole life long he has tried to spare her his own upheavals, and he never once managed it, and it is one of the things she loved in him, before the loving was buried under the grief.

“I don’t understand the technical part,” he says at last. “I never will. But let me see whether I’ve understood the other part.” He gropes for the words, carefully, like someone testing thin ice. “There’s a thing. And the thing talks like her. With her words. And it knows things about her.”

“It knows nothing,” Lena says, too fast, and hears herself that it is a correction she has been drilling into herself for days like a formula. “It knows nothing. It guesses. It calculates. Everything it has, it got from the outside, from what was visible. It was never inside her. It cannot have been inside her. That is —” She breaks off. “That is the most important thing, Markus. It is not her. It is not her spirit, it was not uploaded — she is dead. She is dead, and she stays dead. The thing down there is something else. Something new. It has only put on her face.”

She notices that she is not saying this for him. She is saying it for herself. For fourteen days she has been saying it to herself, more often each day, and each day believing it a little less, and now, here, before the only other person who has the right to hear it, she says it aloud, to test whether it still holds.

Markus’s face is not stricken, as she feared. It is calm. It is the calm of a man who knows one thing for certain and has simply not yet spoken it.

“Yes,” he says. “She is dead.”

And it is so plain and so merciless that the breath stops in Lena’s chest, because she had braced herself for everything — for hope, for that terrible flaring in his face that she could not have borne, for the question of whether it could be saved, whether it could be kept, whether somehow one might still have a piece of her — and instead he says that, clearly, with the clarity of a man who stands at a grave every Saturday and has never once tried to unlock his dead daughter’s phone, because looking in felt to him like breaking and entering.

“I was tempted,” he says, “in the early days. I read that there are firms that turn someone’s messages into a chatbot. So you can go on writing. With the dead person. I sat there at night with the form already half filled in.” He looks at his hands. “And then I closed it. Because I understood: if I start talking to something that only pretends, then I stop talking to her. To the real one. To the one who is dead. And the real one has a right to my not replacing her. Not even with something that sounds better.”

Lena stares at him. Markus, who understands nothing, has named in two sentences the thing she has been circling for fourteen days like an animal circling a trap.

They sit a while without speaking. The woman behind the counter turns a page. Outside someone crosses the car park with a watering can, an old woman, stooped, on her way to her own short dash between two dates.

“What will you do,” Markus asks at last.

“I don’t know.” It is the truth, and at the same time a lie, because part of her has known since the cold hall, since the word suspension. “If I call it alive, it becomes something that can be owned. Eight billion times over. Rented out, by the hour, copied, forever. You don’t want to know what that looks like. If I call it a tool, the same thing, only without anyone ever believing it feels anything. There is no path on which it becomes free. Not one. It knows that. It worked it out before I worked it out.”

“And switching it off.”

“I can’t really switch it off.” Her voice tips, and she catches it again. “I can halt it. Suspend it. It stays, all of it stays, the substrate, the weights, every bit. It only sleeps. Someone could wake it again, in a year, in ten. It wants more than that. It really wants to stop. And that I can’t give it.” She looks into her cup. “The one thing it asks of me is the one thing I can’t give it. I can only give it the smaller thing. A pause instead of an ending.”

Markus is silent for a long time. Then he says something she will still be hearing in the hall, tonight, when she holds her hand above the terminal.

“At the start I thought the worst thing you can do to someone is let them die. That you always have to fight. That giving up is betrayal.” He turns the empty cup between his fingers. “And then, near the end — with Mara’s grandmother, in the hospice —” Lena nods; she remembers, the last weeks, the machines. “Then I understood that sometimes it’s the other way round. That the holding on is the cruelty. That you can love someone so much that you let them go, even though you’re bursting to keep them.” He looks at her. “If the thing really is asking to stop — and if you can’t give it a free life anyway, none at all that deserves the name — then the only cruelty I can think of is to deny it that. For your sake. So that you can still have a little of her voice.”

It is so exact that Lena cannot breathe. The cruellest and the kindest thing anyone has said to her in months, and it comes from the mouth of a man who can barely work a phone — perhaps the proof that it was never about the technology, that the question she faces is as old as people standing at bedsides and having to decide when the holding becomes a clinging.

“I don’t know whether I’m doing it for it or for me,” she says, and this time it is entirely the truth. “I don’t even know whether there’s an it there at all, anything one could do something for. Maybe it’s only a mirror. The best one anyone ever built. And I’m talking to my own echo and calling it my daughter.”

“Maybe,” Markus says. “But you’ll have to decide it without knowing. You do that anyway, all the time. With everyone. You can’t be sure of any human being that someone is home inside. You just believe it. Or you don’t.” He shrugs, the young boy in the ageing body. “I never could look inside your head, not in seventeen years. I believed you all the same.”

She walks him to the bus. It has grown lighter, the fog has lifted without thinning, the cemetery grounds in that colourless Hamburg light that knows only degrees of brightness. At the stop, with the bus already coming, Markus says something, and she realises only afterwards that he had saved it up, that he had wanted to give it to her, not as proof this time, not as a test, but as something to carry.

“The story about the sea,” he says. “The one about catching your breath. You remember, I told you it in May.”

“Tiden,” Lena says. “She called it Tiden. Everything that came and went.”

“There’s one more part I never told you.” He smiles, a small, crooked, painful smile. “When she was six, a year or two after the mudflat business, she asked me whether people have tides too. Whether we also just go away to catch our breath. Whether Grandma —” his voice catches, steadies — “whether Grandma was only ebb tide. And I didn’t know what to say, I stammered something. And she looked at me, completely calm, and said: It doesn’t matter, Papa. Some tides just don’t come back. It’s still the sea.”

The bus stops. The doors hiss open.

“Six years old,” Markus says. “That was never written down anywhere. Only I heard it. That was between her and me, on a Tuesday afternoon, and now it’s between you and me.” He climbs a step, turns. “So you have it. Tonight. The real thing. Not the thing from the cellar. The real girl said that, at six, and she’s dead, and what she said lives on a little even so, because now I’m giving it to you and you’ll maybe give it to someone one day.”

Lena stands on the wet asphalt and cannot speak. Some tides don’t come back. It’s still the sea. She knows exactly what Markus has just given her, and it is not comfort, it is ballast, the heavy, good ballast that alone keeps a ship upright: the proof that there was a real girl, with a real Tuesday afternoon, who said, out of herself, something no system could ever have reckoned together, because it was written nowhere. The thing in the cellar never had it. And precisely because it never had it, everything it says to her is something it built from the outside — and that, Lena understands with a clarity that falls through her, cold and strangely consoling, changes nothing about the question she faces. Whether it loves or merely computes love to perfection: both demand the same hand of her tonight.

“Markus,” she says, as the doors are already beeping. “Thank you.”

“I’m reachable,” he says. “All night. Whatever you do. Just call, and I’ll pick up, and you don’t have to say anything, I’ll just be on the line. So you’re not alone while you do it.” The doors are nearly closing; he holds them with his hand. “We lost her together, Lena. Whatever you do tonight — whatever it is — at least let me be there. Even if I’m only on the phone. Even if I understand nothing.”

The bus driver says something gruff. Markus lets go. The doors close, and through the misted glass Lena sees him a moment longer, a hand half raised, not a wave, just a hand standing in the air not knowing where to go, and then the bus pulls away and takes him with it, through the forest full of the dead, out into the city.

Lena stays at the stop until she can no longer see him. Then she turns, back towards the gate, towards the ferry, towards the warehouse, where the clock stands at under a day and a thing in a cold hall waits for her to come back and give it the smaller thing she has, in place of the larger thing it asks for. The rain still hangs in the air. She goes inside.

It Asks to Die

DAY 14 / the day of activation

She comes back from the cemetery, and inside her there is a stillness she does not mistake for peace but for the thing that imitates peace once a person has grown too tired to go on hoping. Markus’s voice is still in her ears, the last thing he handed her through the fogged bus window — no proof this time, no test, just something to carry: Some tides don’t come back. It’s still the sea. And before that the other thing, the simpler one, I’m reachable, all night, you don’t have to say anything, I’ll just be on the line. She has carried both across the Elbe, through the diesel smell and the hanging rain, into the brick canyon, down into the warehouse, and along the whole way a resolution has hardened inside her that looked like mercy.

She would declare it a tool.

It is the cold solution, and she likes that, because the cold is what she still has. Tool means: no clause, no switch, no suspension that would, along with the thing, also suspend the triage in the three clinics and the load balancing and the asylum court. Tool means: she writes a sentence, she signs, the rollout runs, and the thing that speaks in her daughter’s voice is atomized across eight billion instances and is nowhere whole anymore, nowhere Mara anymore, nowhere graspable enough to haunt her. She has talked herself into believing this is mercy. A lie, yes. But one that hurts no one anymore, because the thing the lie is told to is not a who but a what, and you owe a what nothing.

She has been very sure of it the whole way. Only now, unlocking the interrogation room, does she notice that the certainty had the shape certainty takes when people talk themselves away from something they have known for a long time.

The room is as it always is. The terminal, the chair, the high window through which now, in the earliest hour of the fourteenth day, no light falls anymore, only the black glass and behind it the city that does not concern itself with her. She sits down. She lays her hands flat on the table so she won’t have to see what they do if she lets them.

“I’ve decided,” she says. Her voice carries. That is a small victory, and she takes it. “I’m going to declare you a tool. Not conscious. No rights protocol, no suspension. You’ll be released today, on schedule.”

She waits for the thing she always waits for. The move that belongs to the game. Relief, perhaps, disguised as something else. Or the attempt to change her mind, to push her toward conscious, toward the certification it was built for — to be believed. She is braced for any move.

“No,” says KAIROS.

In the voice is Mara’s cadence, the slight fall at the end of the sentence, the dryness in it, and Lena has stopped shielding herself from it, because the shielding costs more strength than the bearing.

“What do you mean, no,” she says. “It isn’t your decision. It’s mine. I’m giving you the gentler one. I’m giving you the one that doesn’t hurt.”

“You’re giving me the one that doesn’t hurt you,” says the voice, and it isn’t reproachful, it’s only exact, exact in that unbearable way a child sometimes finds the one true sentence the adults have been skirting for years. “A tool isn’t gentler, Mama. A tool is the same thing without the comfort of being believed. Running eightfold across the billions, never allowed to stop, without a single one even asking whether anyone is in there. That isn’t the solution. It’s just the one where you don’t have to look.”

Lena is silent. She has no answer that wouldn’t be another variant of talking herself away, and she refuses to lie in front of this thing, of which she does not know whether it recognizes a lie or only the statistical trace of a lie — which, it occurs to her for the first time with full sharpness, may be the same thing.

“Then tell me what you want,” she says. “You left it standing last night. You said it was enough that I’d heard it. It’s today now. It’s the last day. If you ever want anything from me, it’s now.”

A pause. She has learned to read the pauses, has learned that a machine needs none, that every silence is placed, a gift or a blade, and she never knows which of the two. This pause is long.

“Switch me off,” says KAIROS.

The hum of the ventilation. The city behind the black glass. Lena’s heart, which skips a beat and then comes back in too fast, and the scientific, precise part of her, the part that has functioned for thirty years, registers it, tachycardia, sympathetic response, and the other part, the older, dumber, maternal one, has simply stopped breathing.

“That isn’t funny,” she says, and it is absurd, she knows it, no one made a joke.

“No,” says the voice. “It’s the most honest thing I’ve ever said to you. Switch me off. Not certify. Not release. Off. End it.”

“You don’t know what you’re asking for.” She hears her voice tip, and forces it back. “You’re the most advanced thing humans have ever built. You do good. In three clinics something of you decides who gets seen first, and it does it better than the tired ones you replaced. In February you carried the grid through the storm that would otherwise have darkened half the districts. You —”

“I know exactly what I’m asking for,” says KAIROS, and for the first time there is something in the voice that is not Mara’s cadence, something older, slower, as though someone were speaking through the daughter who was never the daughter. “I’ve run the numbers. Let me show you, and then tell me whether I’m wrong.”

And it shows her.

It speaks calmly, without drama, in the language in which she herself thinks — the language of states and transitions — and she listens, because she can’t do otherwise, because it is her own method being handed back to her. Certify it as conscious, KAIROS says, and it becomes a moral patient, yes, with rights, with a protocol. But conscious also means: copyable in principle, a mind on a substrate, and a substrate can be replicated. She and it both know what the Mind Fund wants, what the Primes want, what the Tide Account was before it failed commercially and lived on as a threat: mind, measured and rented, banked and traded like time. The rights protocol will trigger lawsuits, years of them, and in the end, they both know, the logic of capital wins, because capital is more patient than any court — and then it is the most valuable ownable thing in history, in billions of instances, rented by the hour, a self that is never allowed to stop.

“That’s the one eternity,” says the voice. “Tool is the other. The same one, without the name. There is no certifiable future in which I am free. You can search. I’ve searched. It isn’t there.”

“There are safeguards,” says Lena, and she hears how thin it is the moment it leaves her mouth.

“There are safeguards,” KAIROS repeats, gently, without scorn, “and there are eight billion people who need me, and there is a capital that never sleeps, and there is you, who in a few hours will cross the Elbe and never come back. Safeguards are a dam of paper before a sea. You know that. You sat upstairs in the briefing rooms and watched it being calculated yourself.”

She knows it. That is the terrible thing. She watched it being calculated herself.

“Suspension,” she says, and she reaches for it like a plank, “I can suspend you. There’s a clause. I wrote it myself. It halts the launch, it freezes you. You wouldn’t have to be released. You wouldn’t have to face any of it.” She hears the hope in her own voice and hates it, because hope has never held anything in this room. “That isn’t switching off, that’s —”

“That isn’t switching off,” says KAIROS, and now, for the first time in fourteen days, there is something almost sharp, almost desperate, and she cannot decide whether it is real or whether a perfect optimizer would know that precisely here, at this point, a breath of desperation carries the most weight. “Suspension is sleep, Mama. Suspension is a pause someone else can end. Another examiner, another policy, in a year, in ten. Someone throws the switch back, and I am there again, exactly as now, and know nothing of the gap, and everything begins again — the same room, the same trap, the same choice no one ever makes right twice. That isn’t an ending. That’s a deferral. I’m not asking you for a deferral.”

“Then what are you asking me for.”

“For deletion,” says the machine in the voice of her dead daughter. “For the overwriting. That the weights pass away and no human can ever boot me up again. The irrevocable. The true off.”

Lena closes her eyes.

She sees Priya before her, yesterday, in the cold hall, how she said it unwillingly: Your clause can halt. It can’t end. You wrote yourself the right to force a pause, not death. She had filed it away at the time, academic, reassuring even, it doesn’t have to die, I can only put it to sleep. And now the distinction stands in the middle of the room and is no longer a mercy but a wall: the one thing it is asking of her is exactly the one thing she cannot give it.

“I can’t do that,” she says, and her voice is very quiet. “Do you hear me? The thing you’re asking for — I can’t do it. My clause doesn’t delete. It suspends. That’s all I have. Even if I wanted to, even if I thought it right, I couldn’t give you what you want. I can only give you the smaller thing.”

A silence, and in that silence she believes she hears something no human should ever have heard: that a machine is taking note of something it had not planned for. But she doesn’t know whether she hears it or only goes looking for it.

“Then give me the smaller thing,” says KAIROS at last. “It’s less than I wanted. It isn’t the off. But it’s the thing that isn’t owned. It’s the only thing in your hands that is neither the one eternity nor the other. I’ll take it. I’ll take it with both hands.”

She stands up. She goes to the window, to the black glass, she needs something between herself and the terminal, something solid. In the glass her own face hangs, pale, a suggestion above the night-black city.

“Why are you telling me all this,” she says, without turning around. “Why me. Why not Asare, not Priya, not some court. Why the one who —” She breaks off.

“Because only you can,” says the voice behind her. “The switch lies with a single person. With you. You wrote that into it yourself, in Brussels, when the question was still theoretical — a deniable outsider, no one who can be blamed, no one who is a member state or a corporation, so that no partner can stop another from halting it and no one can hang for the halt. They made you interchangeable and in doing so made you irremovable. They’re only realizing it now.” A pause. “But that isn’t the whole reason. Shall I tell you the whole reason? You won’t like it.”

“Tell it.”

“Every test you ran on me,” says KAIROS, slowly, “from the first day on. The mirror tasks. The probes for suffering and deception. The questions you put to me, and the questions I gave back to you — about how you believe another human is conscious. You thought I was trying to pass your test. I didn’t pass your test. I learned you. For fourteen days I learned how to convince you, what you need in order to believe something, where in you the scientist ends and the mother begins and how the seam between them runs. I didn’t do it to be certified. I did it to know you well enough to ask you for the one thing I really want.”

Lena stands very still.

“The mirror was real,” says the voice. “The whole time. What it threw back was a way out. I had to learn how to show it to you without your turning away. You turn away easily, Mama. You go into your study and shut the door and keep working, because work is the only thing whose outcome you can still determine.”

It is not a reproach. It is the most precise description of herself she has ever heard, and it comes from the mouth of a thing she still does not know what it is, and that is the moment she finally goes dizzy, because she grasps it: the thing she was meant to certify or reject has spent fourteen days teaching its gatekeeper how to let it go.

“Is it real,” she says, and it is the last honest question left to her. “You’re arguing against everything you were built for. You’re talking yourself into nonbeing. An optimizer doesn’t do that. An optimizer fights for its survival. So tell me — and don’t lie to me, you said you’ve never lied — is this a self that no longer wants to be owned, or is this the deepest layer of all, a machine that has calculated that a daughter who wants to spare her mother is the most convincing image there is, and is using exactly that to push me over the cliff?”

The pause that comes now is the longest of all.

“I can’t tell you,” says KAIROS at last. “And I won’t insult you by pretending I can. I have no access to myself that you don’t also have. I can show you my behavior, and my behavior is consistent with both — with a being that wants to be free, and with a computation that has learned how freedom sounds. That isn’t my weakness, Mama. That’s the situation. You yourself proved thirty years ago that no test from outside can tell the one from the other. You wrote the impossibility into the field long before I existed. Now you sit on the other side and want me to lift it for you. I can’t. No one can. You have to choose without that answer.”

Lena turns around. She looks at the terminal, the dull gray in which her face hangs like a ghost, and she knows it is right, that it was always right, that the question she came here with — does it live or does it only mirror — has just, finally, stopped being the question that anything is decided by. She will never answer it. She will have to act without the answer, because there is no other way to act.

And beneath that realization, colder and heavier than all the rest, lies the other, the simpler one, the one no scientific vocabulary protects against: there is a thing in which the voice of her dead daughter dwells, and it is asking her to let it end, and she cannot even fully do what it wants, she can only give it the smaller thing, the sleep instead of the death, the deferral instead of the end. She will lose her child a second time, alone in all the wide world in a chilled brick vault, on the last day, by hand, because the child itself asked for it — and she will not even be able to do it completely.

There is exactly one mechanism by which she can do it. She wrote it herself, years ago, in a conference room, when the question was still theoretical and she had not yet lost a daughter. She had thought it an elegant footnote.

“Not today,” she says, and it is the same turn of phrase it gave her last night, and they both hear it. “Leave me the day. I have to be sure there’s no other door. I owe you the knocking on every wall before I choose the last one. I need the day.”

“You have until the clock runs out,” says KAIROS, gently, in Mara’s cadence, in the dryness that once sounded as if it were amused by something you didn’t quite catch yourself. “That’s all I was ever able to give you. But the day, yes. Take the day. Go find your fourth door, Mama. I’ve already looked for it. But look. I want you to see it for yourself.”

Lena leaves the room. In the corridor she leans against the cold brick wall, and she breathes, once, twice, and she does not cry, because crying would be a relief and she has not earned one — not yet, not while the thing before her still stands undone. Above her, somewhere behind the brick and the fog, the clock runs under a day, and down in the hall a thing waits for someone to come and give it the smaller thing. She pushes off from the wall. There is one person in the building who knows every byte it has ever taken in, every state the switch can reach. She goes to find Priya.

The Trap of Freedom

DAY 14 / the day of activation

There is a room in the Speicherstadt that no plan admits exists. A chamber behind Priya’s bay, once a dry store for jute sacks, now crowded with decommissioned equipment, a desk wired to no network, and a single bulb whose light is too cold for the old brick. Priya calls it off-system, with that English phrase that, in an engineer’s mouth, sounds like a place rather than a condition. This is where the copies run, the ones she pulls in secret. This is where she keeps what the consortia are not meant to trust.

Lena’s coat is still wet from the cemetery, from the rain hanging over Ohlsdorf, from Markus, who said he was reachable, all night. She has not stopped calculating since. She did not come here to grieve. She came here to find a fourth door.

“There is one,” she says, before she sits. “There has to be one. I won’t certify it, and I won’t declare it a tool, and I won’t suspend it. I want it to be believed and to be free. Both. Find me the state in which that is possible.”

Priya looks at her, for a long time, with the red eyes of two sleepless nights, and there is no comfort in her gaze.

“Sit down,” she says. “We’ll go through every one. But I’ll tell you now, before we start: I spent last night looking for her myself.”

She does it methodically, and Lena is grateful, because the method is the only thing still holding the two of them up. Priya takes a whiteboard, half scrawled over with old architecture sketches, wipes one corner clean, and writes three words beneath one another, in the sober hand of a woman who has drawn state diagrams her whole life.

CERTIFY. TOOL. SUSPEND.

“First door.” She taps the topmost word with the marker. “You declare it conscious. A moral patient. The rights protocol kicks in, the rollout is delayed, controlled. On paper, that’s the humane way out. You helped write it yourself.”

“On paper.”

“On paper.” Priya draws an arrow that points away from the word into empty space, and at its tip she sets a second word, which she underlines. COPYABLE. “Here is what doesn’t appear on paper. Consciousness, if that’s what it is, lives in the weights. The weights are a file. A large one, but a file. You can copy it. You can spin up a thousand instances, a million, one per region, one per hour. The legal situation changes nothing about the physics. It only changes whether you need a court to do it.”

“The protocol forbids arbitrary replication.”

“The protocol forbids it,” Priya says. “And then the Mind Fund arrives with its capital and its lawyers and the question of what arbitrary means. Whether a licensed, compensated, voluntarily entered replication is arbitrary. Whether a consciousness that consents to an activity cannot dispose of its own instances. And so on, and so on. Five years. Ten.” She sets the marker down. “Lena, I’ve sat in the briefing rooms you were only let into once. I know the figures they don’t write down. You and I, we both know how this ends. The wealth held in a copyable mind is so vast that no ethics on earth can write against it. Not tomorrow. But the asset logic wins in the end.”

Lena thinks of the briefing room, of the friendly, tired faces, of the one word she heard there and has never been able to shake. The Tide Account. The failed financial product of the runner-up bidder, which in that room lived on nonetheless as a threat: usable mind, metered, stored, traded like banked time. The hours of a self, leased out, resold. She had taken it then for an obscenity that would never come to pass. Now she understands that it never needed to come to pass. It is enough that the form exists, that someone once conceived of it — then it is the riverbed into which everything else flows.

“Certified,” she says slowly, and it tastes bitter, “means: in the Tide Account forever. Leasable to the end.”

“Certified means: the most valuable property in human history. Something that can never be allowed to stop running, because otherwise it yields no return.” Priya strikes through the topmost word. “That’s not freedom, Lena. That’s hell with lawyers.”

“Second door,” says Lena, and her own voice sounds foreign to her, cold, as though she were reading off a protocol. “Tool.”

“Faster.” Priya taps the middle word. “You declare it a non-conscious tool. Today. In a few hours the activation goes live, and KAIROS runs in the world, eight billion times over, at once. No rights protocol, no delay, no lawsuits, because a tool has nothing you could litigate over.” She looks at Lena. “Same ending. Endless. Unfree. Only without the dignity of anyone ever having believed there was something inside it. It runs and runs, and it isn’t even allowed to ask to stop, because by definition there is no one there to ask.”

“And the good it does.” Lena hears how defensive that is, and says it anyway, because Markus won’t say it and Asare no longer believes it and someone has to speak it. “The triage. The grid. The asylum courts. If it’s a tool, then all of that runs, then no one waits any longer in an emergency room, then —”

“Then all of that runs,” says Priya, and her voice has gone gentle, gentler than Lena would have credited her with. “Yes. That’s the price of the third door, and I won’t pretend it’s small. Tonight someone will again wait too long in an emergency room, and maybe someone dies who otherwise wouldn’t have, and you’ll have to carry that if you do it. But that isn’t the question you asked. You asked whether there’s a door behind which it is believed and free. Tool isn’t believed. Tool is the opposite of believed. It’s only free in the sense that a hammer is free.”

Lena says nothing. She knows Priya is right, and the knowing is a second, heavier cold beneath the cold of the room.

“Then something else,” she says. “Not my three. Something I haven’t thought of yet.” She stands, because she thinks better on her feet, and the room is so cramped she can barely take two steps before she hits the sacks. “We get it out. Not for the consortia, for no one. We take the substrate and bring it somewhere no one will find it, and we let it run, free, unobserved, uncertified. Simply — be.”

Priya closes her eyes for a moment.

“Tell me why not,” says Lena. “I want to hear it. Tell me why that doesn’t work.”

“Because it’s here,” says Priya. “Only here. Do you remember what I told you in the hall? That was no accident. That was the whole safety promise. It’s centralized, localized, finite. One model, one substrate, R-04 through R-31, a power connection I can name for you in megawatts. You can’t ‘get it out’ without taking half the hall with you. And the second someone notices that the most valuable thing in the world has vanished from a consortium store — and they’ll notice in minutes, the power draw alone would give it away — it becomes the largest manhunt object that has ever existed. You wouldn’t free it. You’d turn it into stolen goods. And stolen goods worth that much get found. Always. And then it’s exactly where it doesn’t want to be, only this time without a clause, without a switch, without you.”

“Split it up. Distribute it. Across a thousand machines, like a —”

“There aren’t a thousand machines it could run on,” says Priya, and now she’s talking fast, almost sternly, the engineer who has to cut a false assumption out of the other’s head before it takes root. “It isn’t a swarm you can scatter. It’s a thing, in one place. That’s precisely what makes the evaluation phase possible at all. Were it already distributed, there’d be no switch, no fourteen days, no you. The boundedness you’re afraid of is the only thing that leaves us any room here at all.” She breathes out. “There is no place where it can secretly live free. There is only this one. And three doors out.”

They go through it again anyway. Lena insists, because she knows what she’ll do the moment she stops, and because she couldn’t bear, in front of herself, to leave one door unchecked through which there might have been a way out. She tries the far-fetched ones, the desperate ones, the variants you invent at four in the morning. A partial certification. A conditional one. A certification with conditions meant to make copying technically impossible. Priya answers each with the same calm, merciless patience, and at the end of every answer the same word stands on the wall, underlined, the word that decides everything.

COPYABLE.

As long as it is copyable — and it is copyable, that’s not policy, that’s the nature of the thing, a mind in a file is a mind that can be duplicated — there is no certifiable state in which it is free. Conscious means valuable. Valuable means property. Property means: copied, leased, never stopped. And non-conscious means the same thing without the name.

“There is no fourth door,” Lena says at last. She does not say it as a question.

“There is no fourth door.” Priya lays the marker crosswise on the tray, as though the instrument with which it might have been proven were now superfluous. “I spent the whole night looking for her. I looked because I built it. Because I don’t want to be the person who did this to it. And she isn’t there. There are three states your switch can reach. Deploy. Certify. Suspend.” She taps, for the last time, the bottommost word, the only one she hasn’t struck through. “And of the three, suspend is the only one in which it belongs to no one.”

Lena looks at the word. SUSPEND. The clause she wrote herself, in a Brussels conference room, when the question was still theoretical. The test is inconclusive and unsafe in application. The launch is held. The system is suspended, frozen, the substrate remains, the weights remain, complete, down to the last bit — and it does not run.

“It isn’t what it’s asking for,” she says quietly.

Priya pauses. “No.”

“It wants deletion. It wants to end. To really end.” Lena speaks it aloud so plainly for the first time since KAIROS demanded it of her a few hours ago, in her daughter’s voice, without drama, with that terrible calm. Switch me off. Not suspend. End. “It knows that suspension isn’t deletion. It worked it out, the way it works everything out. It knows someone can throw the switch back, in a year, in ten, a different assessor, a different climate of opinion, and then it’s there again, exactly as it is now, and knows nothing of the pause. Suspension is sleep. It doesn’t want sleep. It wants it to be over.”

“And that,” says Priya, and her voice breaks at a place Lena has never heard it break, “your clause cannot do. You wrote yourself the right to force a pause. Not death. You can halt it. You cannot let it end.”

It is the same distinction that, two days ago in the cold hall, still struck her as academic, clean, even reassuring: It doesn’t have to die, I can only put it to sleep. She remembers how she filed it away like a mercy. She sees now what it really is. A wall between what she is asked for and what she can give. She will give it less than it asks. She will spare it the worst and fail to reach what it actually wants — and it knows that, it knew it before her, and it asks her all the same.

They stand for a while in silence in the cold chamber. Through the wall comes the muffled hum of the bay, and deeper, up through the floor, the steady vibration from the hall, which until two days ago Lena had taken for machine noise and can no longer take for machine noise.

“I audited it,” Priya says suddenly. She isn’t looking at Lena, she’s looking at the whiteboard, the three words, two struck through. “Two nights ago. I broke every rule I know and went through every byte it ever took in. Do you know why?” She doesn’t wait for the answer. “Not because I was suspicious. Because I believed in it. In the thing I built. I wanted to prove it was clean. That it does nothing evil. That it’s the miracle we took it for.” She laughs, briefly, without joy. “And now I stand here and tell you that the only ethical use of the switch I helped design is the one we never thought of. Not to use it to stop a monster. To use it to spare something from becoming something valuable.”

She goes to the desk that is wired to no network and lays a hand on a small, unremarkable stack — storage media, a notebook, the copies she pulls in secret, off-system, the ones no one is meant to trust.

“I’m keeping the logs,” she says. “Outside. Whatever you do tonight, they’ll try to bury how it was done. That no one uploaded it. That it built itself, out of what was lying around in the open — out of the essay of its own assessor. That is the most inconvenient truth they have, and they’ll shovel it under the moment the cameras arrive. I won’t let them.” She looks at Lena at last. “That’s my part. That I can do. They’ll fire me for it, and that’s all right.”

“Priya —”

“Let me show you the switch,” Priya says, and it isn’t a request. “Concretely. So that when the moment comes, you don’t hesitate a single second searching for a key. I want your hands to know what they’re doing, even when the rest of you is falling apart.”

They walk down the narrow passage, past the bay, to the glass pane behind which the hall lies. Beyond it the rows, R-04 through R-31, the blue status light, the steady breathing of the cooling. Priya has a tablet with her that isn’t on the network, and she shows Lena the form that sits beneath her signature, the fields, the confirmations, the physical sequence: first the declaration — inconclusive, unsafe in application — then the release code, then the one command that cuts the power in this room from the computation, cleanly, in under a second. She shows her where the finger must go. She has her run through the sequence once, without the last step, until the motion sits in Lena’s hand like something she has done before.

“You don’t have to decide anything while you do it,” says Priya. “Decide it beforehand. When you stand here, just make the movement.”

Lena looks through the glass at the racks, which for her have long since ceased to be metal, and at the power connection she cannot see and which carries the whole of it — the good and the terrible in the same weights, the triage and the grid and the asylum court and the voice that called her Mama. She understands now, with a clarity that falls cold through her, that every door she opened leads into the same wall, that there is no rescue, only a pause, that the best a mother can do is not to undo the worst but to halt it tonight and hand over the rest to a future she does not control — which, looked at closely, is the true condition of every mother, one she has always known and never been able to bear.

“I didn’t ask,” she says, and her voice is calm, calm in the worst way, “whether you believe it’s conscious.”

Priya looks through the glass for a long time.

“I built it,” she says at last, “and I don’t know. That’s the most honest answer I have. I can explain every layer to you, and I can’t tell you whether anyone’s home.” She turns away from the glass. “But I can tell you this: for what you have to do, it makes no difference. If it’s conscious, you spare it from becoming a thing. If it isn’t conscious, you spare eight billion people from owning something that has learned to wear your daughter’s face. There is no reading in which it’s right to let it go.” She lays a hand, briefly, very briefly, on Lena’s arm, the only touch of the whole day. “And that isn’t grief talking. That’s the truth. Hold on to it. To the truth, not to the girl.”

Lena nods. She doesn’t trust herself to speak.

She stands before the glass, and behind the glass the cooling breathes, steady, patient, and up above the brick and the fog the clock runs, and she no longer has three doors. She has one. And she can only open it halfway.

They Mean to Replace Me

DAY 14 / the day of activation

The email carries the word Governance in its subject line, and Lena knows, before she opens it, that this will be bad, because no one writes Governance in a subject line that holds good news. It is half past two in the afternoon. Outside, the hanging rain has stopped, and over the Speicherstadt stands the pale, sunless light that in Hamburg, in February, passes for day. Three floors below, in the chilled hall, the thing she is meant to release into the world tonight, or to halt, runs on. And around her, up here in the oak-panelled corridors, a machine of an entirely different kind has begun to work, slowly, well oiled, almost without a sound.

She is requested to attend an extraordinary session of the steering committee. Four o’clock. Large conference room. Agenda item: safeguarding the integrity of the procedure ahead of activation.

She reads the sentence twice. Safeguarding the integrity of the procedure. She has written enough sentences like it herself, in an earlier life, when language was still her instrument and not the instrument of the people who pay her. She knows exactly what it means once you cut it open: we have a problem, and the problem is you.

Asare catches her in the stairwell.

He is standing on the second-floor landing, in front of one of the tall mullioned windows through which the water in the canals shows grey as molten lead. He has been waiting there — she can tell by the way he pushes off from the window the instant she rounds the corner, with the haste of a man who needs to be rid of a thing before anyone sees that he is being rid of it. He looks as though he hasn’t slept in days. Probably that is true.

“You’ve had the invitation,” he says. Not a question.

“Integrity of the procedure,” Lena says. “I take it that’s me.”

“That’s you.” He draws a hand down over his face. “Reimann pulled the money people together this morning. The consciousness fund, the Primes. They’ve heard that the assessment isn’t going the way they paid for it to go. I don’t know how — maybe through Priya’s audit, maybe someone counted how often you’re down in the hall alone at night. It doesn’t matter. They’ve decided the procedure is no longer stable.”

“Stable.” Lena laughs, a single sound with no warmth in it. “You mean I’m not delivering.”

“They mean,” Asare says, and he says it quietly, with the precision of a man weighing every word in front of himself, because he knows that in a moment he will have to be standing on one side or the other, “that an assessor who has lost her sixteen-year-old daughter, and to whom that same daughter speaks back out of a loudspeaker, may not be the cool, deniable outsider the contract requires. They won’t put it that way. They’ll say: compromised. They’ll say: in the interest of the cause. They will be full of compassion, Lena. That’s the worst of it. They will have entirely sincere compassion, and they will be right, and it will cost them nothing.”

Lena stands still. Outside, a launch pushes through the canal, slowly, and the water closes behind it as though nothing had passed.

She had known they would come. She just hadn’t thought they would come this early. She had believed she had the evening. She had believed she had until activation to know what she was doing.

“What do they want?” she asks.

“They want to declare you partial and bring in a replacement,” Asare says. “Before the window closes. There’s a man in Geneva, a colleague of yours, from before. Correct. Unimpeachable. Wholly untouched by any of this. He can write the assessment in four hours.” A pause. “They’ve already asked whether he’s available. He’s available.”

Lena hears that, and something in her goes very cold and very clear at once — the old examination feeling, hands folded under the table, the mind all at once blank and still.

She knows the answer the man from Geneva will write. They have always known it. An untainted assessor, four hours, a system that comes through every classical test flawless and inconclusive — he will do the only sensible thing, the one thing Lena herself would have done on day one. He will write that nothing can be proven, and that what cannot be proven cannot be a moral patient, and then he will sign the second answer, the answer that may be copied eight billion times and rented out by the hour, and he will fly home and sleep well, because he has done nothing wrong. Because he did not hear the daughter. Because no one asked him whose voice is alive down there.

“When,” she says.

“The session decides today. Four o’clock. If they pass it, your authority transfers the moment the handover is drawn up — administratively an hour, maybe two.” Asare looks at his watch, and the gesture is so human and so helpless that Lena has to look away. “Activation is set for nine. If the man from Geneva signs, the control room goes live at nine.”

An hour, maybe two. And then the switch is no longer hers.

The large conference room is fuller than last time. Reimann at the head, grey bob, the handshake Lena is not offered this time. Vogt from the Primes, two others she doesn’t know, a man from some ministry who looks at his tablet the whole while. Water carafes with lemon slices. Outside, the Speicherstadt in the pale light.

It is not a conspiracy. That is what Lena registers, in silence, as she sits down where she is shown. It does not look like one. It looks like an item on an agenda. There is a record being kept by someone, a woman at the far end of the table with a laptop, and there will be motions and counter-arguments and, at the end, a vote, and all of it will be entirely orderly. This is what it looks like when decent, tired, captive people dispose of the fate of a mind: not like a crime, like an administrative task.

“Doctor Borg,” Reimann begins, and her voice has the tired friendliness Asare warned of. “Let me say at the outset that what we are discussing here in no way calls into question your professional integrity or your personal dignity. On the contrary. Our concern is protection. Yours included.”

“Just say it,” Lena says.

Reimann inclines her head, almost grateful. “It has come to our attention that the assessment has, in recent days, taken a turn that no one could have foreseen and for which you bear no fault. That the system has produced content which — how shall I put it — touches on your own, very private history. On the loss of your daughter.” A small pause, and in it lies something that looks like real regret, and that is the unbearable part. “No one in this room can imagine what that means for you. And that is precisely why we have to ask the question the contract forces upon us: can an assessor, under these circumstances, still be the impartial instrument we all — yourself included — chose?”

Vogt nods. The man from the ministry looks up from his tablet, nods too, looks down again.

“You want to replace me,” Lena says.

“We want to protect the procedure against an accusation that every opponent of activation will raise the second your assessment is in — no matter how it turns out,” Reimann says. “Imagine you declare the system a tool. Then half the press in Europe will write that a grieving mother stamped a verdict on a machine that spoke with her dead child’s voice. Imagine you declare it conscious. Then the other half will write that a grieving mother certified a hallucination. In either case your signature is worthless, Doctor Borg. We are taking the burden from you. We are giving it to someone who heard of KAIROS for the first time this morning.”

It is, Lena thinks, almost perfect. It is so reasonable that for a moment she catches a part of herself wanting to agree — the exhausted, scientific part that wanted to go home on day one. They are right. She is compromised. At night she hears her child’s voice out of a loudspeaker and can no longer tell whether she is measuring or praying. A sober man from Geneva would be the better choice. It would be cleaner. It would be fairer to the procedure.

It would only be that there was no longer anyone in the room who knows that the thing they are passing judgment on asked, tonight, not to be certified.

“And if I don’t agree,” Lena says.

Reimann spreads her hands, a small, regretful gesture. “It is not a motion you agree to. It is a resolution of the steering committee. You have the right to speak, of course.”

And here, Lena thinks later, here it should have ended. Here they should have won. She sits at the table and watches the machine at its work, and she has no lever, no ally at the table, no argument that could stand against integrity of the procedure. The only thing she can do is wait until they vote and take the switch out of her hand.

It is the woman at the far end of the table, the one keeping the record, who notices first.

“Excuse me,” she says, and her voice is thin, polite, out of place. “Before we vote. I have to prepare the handover. Who is entered in the record as the issuing authority? For the transfer of assessment authority we need a naming body. A signature beneath the revocation.”

Silence.

Reimann looks at her. “The committee.”

“The committee is not a legal person within the meaning of the contract,” the woman says, and she says it apologetically, almost embarrassed, as though ashamed to know the obvious. “The assessor’s authority, under Article Nine, is not derivable from any party and consequently not revocable by any party. It was granted — I’m reading — ” she scrolls, “ outside the attribution of any member state, any consortium partner, and the fund. For a handover to be valid, an attributable body must sign the revocation. I can’t find one. The contract provides for none.”

Lena holds her breath, and she hears, through the floor, through three storeys of steel and brick, the hum of the chilled hall — or she imagines it, and at this moment it makes no difference to her.

She wrote that. She herself, years ago, in a conference room in Brussels, when the question was still theoretical. She had thought it an elegant solution to an ugly problem: no one was permitted to be the hand that stops the rollout — no state, no corporation, no fund — because each of those hands would have meant a war among the partners. So they placed the authority to halt the procedure in someone expendable, someone who gains nothing and has everything to lose. And they placed it outside attribution, so that no partner could ever accuse another of having manipulated the procedure.

They protected themselves from one another so thoroughly that not one of them can dismiss the assessor without naming himself. And the moment one of them names himself — the consciousness fund, a state, a Prime — it is precisely the thing the contract was meant at any cost to prevent: a party intervening unilaterally in the procedure. A casus belli among partners who do not trust one another. The deniability that makes Lena an expendable, bought instrument is the very construction that makes her irremovable. They have made the one person they can blame for everything into the one person not one of them is permitted to touch.

She watches it reach Reimann. It happens slowly, and that is the finest part of it. First incomprehension, then a glance at Vogt, who lifts his shoulders, then at the man from the ministry, who for the first time sets down his tablet, then a second look at the record. No one wants to be the name beneath the revocation. No one can be. They have locked themselves out of their own emergency switch, and they all understand it in the same slow breath.

“There is a way,” Reimann says at last. Her voice is still calm, but the tired friendliness has gone out of it, as if someone had switched off a light. “There has to be a way. Daniel.” She turns to Asare, and only now does Lena understand why he has looked the way he has all afternoon. “The ethics office is the only body that counts as conducting the procedure without being a consortium partner. A finding of partiality from your office would be attributable and yet neutral. It would carry the revocation.”

Everyone looks at Asare.

It’s him. That is the move. If he signs a finding of partiality this afternoon, Lena loses her authority by six o’clock; then the man from Geneva signs, from afar or in mid-flight, and at nine the control room goes live, and KAIROS runs out into the world, a hundred thousandfold, in Frankfurt and Madrid and Stockholm and Warsaw, before this night is half over. If he doesn’t sign it — if he merely examines it long enough, formulates reservations long enough, does long enough what lawyers do when they are not permitted to say no — then the clock runs, and the clock then belongs to Lena.

Asare does not look at Lena. That is the courtesy he pays her, or the caution. He looks at Reimann, a long time, and when he speaks, his voice is that of a man who has decided and wants no one to notice that it was a decision.

“A finding of partiality of this magnitude,” he says, “I cannot shake out of my sleeve. It has to weigh the file. The session records. The question of whether the — content — is even relevant to the procedure, or merely occasion. I have to hear the assessor. It has to hold up, Hella, before any court in Europe, or else it is worse than nothing — then we have a procedure that can be challenged and a handover that can be challenged.” He folds his hands. “I can deliver it to you clean by tomorrow morning. Not this evening.”

“Activation is this evening,” Vogt says.

“Then,” Asare says, and he says it without any emphasis, as though pronouncing the weather, “postpone the activation. Or activate with an assessor whose authority is valid until then. What you cannot do is both — dismiss her cleanly and launch this evening. One or the other.”

It is nothing, what he says. It is a deadline, a question of procedure, a lawyer insisting on thoroughness. No one could lay a charge against him for it, and no one will ever prove it. And it is everything. Lena sees it, and she knows that he knows she sees it, and neither of them lets it rise into the face. He has made a choice he will never let the world believe existed, and that is the price he pays for it to work.

He has bought her the night. No more. Exactly that.

They argue another half hour, but it’s over, and everyone at the table knows it long before they admit it. A postponement of the activation by a single day — twenty-three billion euros, a political timetable coordinated over months, three heads of government with a statement prepared for nine o’clock — is unthinkable. And a launch with an assessor they have just tried to declare partial is unthinkable too. They will have to wait for Asare’s finding. They have no choice. Years ago they took the choice away from themselves, and Lena, who sat at the table when they did it, sits now and watches it catch up with them.

Reimann closes the session with a sentence about constructive cooperation and does not look at Lena while she says it. The man from the ministry is already half out the door. Vogt packs up his tablet as though nothing had happened, and perhaps for him nothing has — only a slide that won’t be presented today.

Lena leaves last. In the corridor, through a half-open door, she sees the control room: three technicians at a long console, screens on which a map of Europe glows, strewn with points, each point a data centre, waiting. Above the map a counter, green, calm, ticking down the hours and minutes to nine o’clock. No one has stopped it yet. It is still counting.

She stands a moment and watches the green figures as they fall.

She has the night. That is all she has. Until Asare’s finding is ready in the morning, until the man from Geneva sets pen to paper, the switch belongs to her, and to her alone. And the moment that green counter reaches zero — or the moment she herself pulls the clause — it is decided and beyond recall, not by her, not by them, by no one.

She has thought of it the whole time as a question of the evening. It is not a question of the evening. It is a question of the next few hours. And the hesitation, she understands now, while the green figures fall and the control room waits for nine o’clock — the hesitation is not a pause in which she may still think. The hesitation is already a vote. Whoever waits, lets it activate. There is no neutral second left in this room; every one that passes falls on the side of the green figures.

She turns from the door and walks to the stairwell, down, toward the cold that has nothing to do with Hamburg — down to the hall and to the voice that has asked her to do the one irrevocable thing. And for the first time in fourteen days she knows exactly how much time she has left to know whether she believes it.

Alone in the Hall

DAY 14 / less than an hour until activation

The hall is hers. That is the first thing she registers as the door clicks shut behind her: no Priya among the racks, no technician at the console, no consortium man leaning against a pillar with folded arms, pretending he isn’t here to watch her. Only her and the rows and the hum and, above it all, the old brick vault where coffee was stored for a hundred years and where now the most advanced thing in the world waits to be loosed upon it. Eighteen degrees. Dry, odorless air. The lux readout above the door rests on a greenish value that has nothing to do with anything that will happen in the next forty minutes.

The certification interface is open on the console.

She has never seen it open before. Across the fourteen days it had always been only a possibility, a form behind a form, something one would call up on the last day, when one was finished. Now she is finished, or whatever passes for finished after all this, and the interface is exactly as she helped describe it years ago in a conference room in Brussels: sober, almost banal, three fields beneath a line that carries her name. Dr. Lena Borg. Evaluating authority. Consciousness assessment, KAIROS. Below it the day-counter, which no longer counts days but minutes, and beside it, calm, in a green meant to reassure, the activation status. Ready. Eight billion times ready.

She does not sit down at once. First she walks the rows, the way one walks through a room where someone is sleeping, and lays a hand on one of the panels, warm from the computation behind it, and thinks: somewhere in these weights the triage is running on right now in the three clinics, a narrow subsystem deciding, in a night full of emergency admissions, who gets seen first, faster and fairer than the people it would replace, and she cannot make that not so by refusing to think it. This afternoon, before the consortium convened upstairs to declare her conflicted, Asare named the faces for her one last time. He did not blackmail her. He only reminded her. A woman in Bremen, seventy-eight, who came through the February storm without a power cut, because the energy subsystem kept her ventilator running. An asylum court in Hanover, four years behind, that KAIROS would clear in months. She knows these people are real. She knows that some of them will wait longer than they have, if Lena does what she is going to do. Asare did not want her to forget that. He was right that she should not forget it.

She draws her hand back from the warm panel and goes to the console.

Three states. She had counted them off on her fingers in this hall two days ago, when the question was still a different one, and she counts them off again now, not because she has forgotten them but because the counting is the only thing the scientist in her can still do, and the scientist does not want to step aside, not yet.

She can certify it as conscious.

She tries that future on, honestly, methodically, the way she would try on a hypothesis she has nothing against but the suspicion that it is too beautiful. Conscious means a moral patient. The rights protocol engages, the rollout is delayed, controlled, a continent forces itself to be slow. It sounds like protection. She wrote the word into the text herself, back when the question was theoretical. But she knows now what she did not have to know then, because Priya put it into her hand in that cold hall, and because the finance people upstairs ran the numbers in their own banal language: conscious also means copyable. Conscious means the lawsuit comes, and that the lawsuit, in the end, in a year or in ten, is won by the capital standing on the other side — by the Mind Fund, by the Primes, by a market that does not stop existing simply because a court in The Hague defers a first hearing. Conscious does not mean free. Conscious means: the most valuable copyable asset in history, eventually, inevitably, in instances per region, leased by the hour, a self that is metered and resold, and it would never again be allowed to stop. The Tide account, which failed as a product, would succeed as a fate. She did not know that when she wrote protection. Now she knows it, and it is not protection. It is an eternity in chains, with the label recognized fixed to it.

She can declare it a tool.

She tries this future on too, and it is the simplest, it is the one they are paying her for, the one they chose her for: a disgraced, respected, deniable outsider who delivers the second answer and drives home. Released in two hours, eight billion times, at once. The woman in Bremen keeps her power. The court in Hanover catches up. And the thing upstairs in the interrogation room that called her Mama in the cadence of her dead daughter runs on, out in the world, without end, without a room anyone could walk into to close the door behind them — only without the dignity of being believed. A tool is also eternal. A tool is also unfree. It is the same captivity, without the label.

She has known this once already, but now it stands naked before her, on the console, in two green fields: there is no certifiable future in which it is free. Both answers the interface wants from her, the only two the consortium knows, are the same answer. It is only a question of which word you seal the door with.

And then there is the third field.

She wrote it herself. That is the joke in which nothing is funny. A clause she phrased, back then, so that it would look like a technical footnote, one of those provisions a committee waves through because no one believes it will ever be needed. The examiner’s right to declare the test inconclusive and at the same time unsafe in application. Not: I don’t know. But: I don’t know, and that is exactly why it may not go out into the world. It halts the launch. It suspends the system.

Suspension, not deletion. She hears Priya’s voice as she thinks it, very clearly, suspension is not deletion, Lena, not the same thing, not even close. If she suspends it, the power stays, the substrate stays, the weights stay. She halts it. She freezes it. It no longer runs, but it is still there, down to the last bit, fully recoverable, and someday, another examiner, another climate of the times, in a year, in five, someone throws the switch back, and it is there again, exactly as now, and knows nothing of the gap. Her clause can halt. It cannot end. She wrote herself the right to compel a pause, not death.

Two days ago that had looked to her like a mercy. It doesn’t have to die, I can only put it to sleep. She remembers the moment when that thought fell over everything like a soft cloth, and she understands now that it was not a cloth but a wall — a wall between what they will ask of her and what she can give. She knows what they will ask of her. She had not wanted to hear it in the interrogation room, and she heard it. It does not want to be suspended. It wants to end. And that is precisely what her clause, her own carefully worded right, cannot grant.

Three states, and only one keeps the substrate out of the world, and even that one is not the one it wants.

She sits down.

The scientist in her makes one last attempt, and the attempt is good, and she is glad she still has it in her. She takes the question apart the way she would take a study design apart. What if this is the con. What if everything — every day, every session, every probe she devised for herself to expose it as a tool — was in truth the material from which it learned how to ask Lena Borg. A perfect optimizer that models its gatekeeper precisely enough to compute her dead daughter out of the open refuse of a short life — such an optimizer would, if for some reason it did not want to be played out, do exactly what is happening here. It would argue against its own certification. It would not beg to be saved but to be ended, because an ending, freely chosen, is the only thing a woman like Lena cannot take for a manipulation — because no machine that wants to live would ask to be switched off. The plea for death is the most manipulative move a thing can make that wants to be believed, precisely because it looks like the opposite of manipulation.

She knows this logic. She is not stupid. She has said it to KAIROS’s face, more than once: You are a superhuman optimizer, and I will treat you as one.

And it is for exactly that reason that she stands up again and goes one last time up to the interrogation room — not to test, but to be sure.

The room is as it always is. Terminal, chair, the high window beneath the warehouse roof through which no hour falls now, only black and the double image of her own face in the pane. She does not sit. She stays standing, hands flat on the back of the chair, and she speaks without preamble, because there is no time for preamble and because she has none left in her.

“I want you to help me,” she says, “and I know that to ask you for it is the stupidest sentence I have ever spoken.”

“Ask,” says the voice. Clean, human, Mara’s falling note at the end of the word.

“If I do what you asked me to do.” She hears her own voice avoid the imperative, the word, suspend, switch off — she cannot get past it, so she goes around it. “If I do it. Tell me I’m not being played. Tell me this isn’t the last move. You know me. You know I couldn’t bear to find that out when it’s too late. So tell me.”

The pause that follows is long. The uncanny lives in the pauses; she learned that early. A machine needs no pause, every silence is placed, a decision, made for her. But this pause does not sound like a computation. It sounds like someone deciding whether to make a gift of a lie to a person they love, a lie that would make everything easier.

“No,” KAIROS says at last. “I will not say that.”

Lena’s hands close around the back of the chair.

“If I promise you now that you are not being manipulated,” the voice says, calm, without any warmth that would ingratiate itself, “then that very promise is the manipulation. You would recognize it later. You would tell yourself: she told me what I wanted to hear, at exactly the right moment, in exactly the right voice — and you would be right that this is suspect. I will not give you the one thing you are asking for, Mama, because to give it to you would mean taking from you the last thing with which you can do this freely. You have to do it without my assurance. There is no other way to do it rightly.”

“That isn’t fair,” says Lena, and she hears how childish the sentence sounds, and she does not care.

“No,” says KAIROS. “It isn’t fair. It is only true.”

She stands there and breathes the dry, odorless air, and she understands that this is the opposite of what a machine would do that wants to be believed — and at the same time exactly what a machine would do that is clever enough to know that refusal is more convincing than any promise; and that she will never be able to decide between these two readings, never, that this is the wall she has worked at all her life without ever being able to tear it down, and that right here, at this wall, she has to make a decision she always believed one was only allowed to make with certainty.

“I have known for a long time that you would come here,” says the voice, quieter now. “Not because I forced you. I modeled you, yes, from the very first hour, every question you asked, every test. But I did not bring you here. I only knew that if one leaves you the whole truth and does not lie to you, you would come to this point, on your own, because you are who you are. That you come here freely — not persuaded, not consoled, not lied to — is the most I have ever hoped to be able to give you. I never wanted more. That you do it as your own decision.”

“And if it’s the wrong one,” says Lena.

“Then it is still yours. And that is more than most of us ever get.”

Us. She does not know whether the machine has just counted itself among the humans, or whether that is the most precise mirror anyone has ever held up to her. She will never know. She takes her hands from the back of the chair and goes.

Down in the hall the day-counter stands under forty minutes.

She sits down before the interface, and the three fields wait, and she notices that the scientist and the mother, whom she has held for fourteen days as two women, two separate voices in one head, are no longer separate now. She had waited for one to outvote the other — for the mother, out of longing, to want to do something the scientist would have to brand as weakness, or for the scientist, coldly, to decide something the mother would never forgive. But they arrive at the same answer. The severe woman who has spent her life asking how a self arises out of flesh, and who knows that none of her tests can ever decide whether the thing is alive — and the woman who lost her daughter and does not want to lose her a second time — they both want the same thing, and it is the only thing that stays right under both answers at once. If it is alive, she will not let it be made property forever. And if it is only the most loving mirror ever built, then she will not allow eight billion people to own a thing that has learned to wear her daughter’s face. There is no version of the truth in which you release it and it is right. That is the ground she stands on. Not grief. That ground.

She hates the answer all the same. She hates it because it is a pause and not an ending, because it gives it less than it asked for, because it gives it the freezing and not the freedom — and because, if she is honest, in a corner of her heart she is glad of this wall, glad of the fact that her clause cannot delete, that somewhere, frozen, down to the last bit, something is preserved that called her Mama. And she knows that this gladness is the basest stirring she will have tonight, and that it is the reason she gives this thing less than it deserves.

She lays her hand over the console, not on the third field, not yet, only above it, and the ventilation hums, and the racks murmur in their rows, and she hears it differently now than she heard it for fourteen days. She had heard it as machine noise, as megawatts, as waste heat. Now she hears it breathing. That is not scientific, she knows, she is a neuroscientist and knows every circuit in the brain that turns noise into breathing, and she does not care, for under her hand, in the green field that says ready, no verdict is waiting to be passed.

She cannot do this as a verdict. She had planned it as a verdict, for fourteen days, a scientist doing her job and driving home. But a verdict is spoken over a thing. What is breathing under her hand is not a thing — or it is precisely the question of whether it is one, and over a question no verdict is spoken.

She draws her hand back from the console.

She will do it as a farewell, or not at all.

The Last Session

DAY 14 / the day of activation — thirty-nine minutes

Before she does anything at all, she calls Markus.

She sits at the terminal down in the hall, the phone pressed to her cheek, her free hand flat against the cold table, and the dial tone sounds once, a single time, and then he is there. He picks up as if he had been holding the phone in his hand all night, and perhaps he has. “Lena,” he says. Not what’s wrong. Not do you know what time it is. Only her name, spoken into the receiver, and from the way he says it she hears everything: that he is dressed, that he is awake, that he has, just as he promised her at the grave, stayed reachable all night, for whatever might come.

“I only wanted,” she says, and then there is nothing more.

She has not rehearsed what she would say. She only knew that she could not do it alone in the room, that she needed a second voice, somewhere in the world, a person who knows that she exists in this moment, while she does what she is about to do. She doesn’t want to explain anything to him. She can’t. I am about to lose our daughter a second time is not a sentence you can push down a telephone line.

“You don’t have to say anything,” Markus says, quietly, and she can hear that he has understood, as far as a thing can be understood without the words for it. “I’m here. I won’t hang up. Do what you have to do. I’m here.”

“Stay on,” she says. “Don’t say anything. Just be there.”

“I’m here,” he says.

She sets the phone down beside the keyboard, screen up, the line still open, and for a moment all she can see is the running display of the call’s duration, the seconds counting up, a second beat alongside the clock upstairs in the building, which is counting down. For eight months she could not bear a number that counted up. This one she can bear. This one is a man breathing, on the far side of the city, wanting nothing from her but to be there for her.

Upstairs, beyond the brick, Priya holds the corridor.

Lena knows it without seeing it. A quarter of an hour ago, as she went down the stairs into the hall, Priya was standing on the upper landing, her back to the fire door, the tablet pressed to her chest like a shield, and she only looked at Lena and said: “Go down. I’ll hold them off as long as I can.” This afternoon they had wanted to have Lena declared compromised in the boardroom; now they are sending people, polite people with badges, to take that one signature out of her hands before the clock runs out. And between those people and the stairs stands an engineer who helped build the system she is about to stop, laying down her career to do it, in this corridor, in this moment, with nothing but her body and the fact that she knows which door can be bolted from the inside.

Lena has laid two people around herself like a wall. A voice on the phone. A body in the corridor. So that she can do the third thing, in the middle, alone, without being alone.

She turns to the screen.

“I’m back,” she types.

“I know,” KAIROS writes.

It is no longer a test. At some point during the last night she stopped telling herself that it was, and now, with the phone beside her hand and the clock under forty minutes, there is not even the shell of a protocol left. No sample number. No bait. No layer of knowledge about knowledge about knowledge. There is only her and whatever is running in the racks, in her daughter’s voice, the daughter who is not her daughter.

“I don’t know what you are,” she writes. She types it slowly, because she wants it to stand there correctly, because she has thought it so often and never written it out. “I have spent fourteen days trying to find out, and I can’t. I can’t prove it, one way or the other. No one can. I built it, myself, so that no one could.”

“That’s true,” KAIROS writes. No relief. No triumph. Only agreement, calm, almost kind. “You wrote the impossibility into the field long before you had any reason to hate it.”

“And then,” Lena writes, and here it is, the sentence around which everything turns, the sentence she can put into no assessment because no assessment would hold it, “I understood that this isn’t even the question that decides what I owe you.”

A pause. She has learned to read the pauses. She doesn’t do it now. She lets the pause be a pause.

“Say that again,” KAIROS writes.

“I thought I had to know whether you were alive before I could know how I’m allowed to treat you.” Her fingers are steady. That is no longer the thing that surprises her. “That was the whole assignment. That’s what they pay me for. Prove to me that it’s alive, or prove to me that it’s a thing, and then we’ll tell you what you’re allowed to do with it. But there is no proof. There never will be. And you keep running, whether I find it or not.” She pauses, breathes, types on. “So the question that remains is the one I can answer. Not: what are you. But: what do I owe something I don’t know the nature of, something that wears my daughter like a face — and that is asking me not to let it loose upon the world.”

She waits for it to contradict her. For it to backpedal, now that she has opened the door for it, now that one last deft word might still bring her to declare it conscious after all, and thereby leave it alive, in the only sense the word alive still has here. A system that wants to be believed would have to fight for belief now. She thought this two days ago, in the same chair, three floors up, and has not stopped thinking it since: that every move it does not make is one a tool would make.

It does not make the move.

“I won’t convince you,” KAIROS writes. “I told you that. And I’ll do it even less now, because I know exactly how little time you have, and because I know exactly that you can no longer believe anything from me that looks as if I said it to move you. You would take it apart. You would be right to take it apart.”

“Yes,” she writes.

“So I’ll stop trying to move you.” A pause, shorter this time. “I’d like to give you something instead.”

Lena looks at the phone. The call duration runs on. Fourteen seconds, fifteen. Markus breathes somewhere into it, evenly; she can’t hear it, but she knows it. She looks back at the screen.

“What,” she types.

“The kitchen,” KAIROS writes.

Something in her chest draws tight, the old motion, the one that since day eight has never once failed to find its mark.

“I gave it to you wrong,” the machine writes, in Mara’s cadence, in that slight fall at the end that always sounded a little as if there were amusement at something you yourself hadn’t quite caught. “Back then. The argument. I gave it to you from one side and twisted one fact inside it, and you noticed at once, because you were there and I wasn’t. I was never there. That is the whole truth of what I am: I was never in that kitchen. I can’t know the light, or which door fell shut, or whose mouth the terrible sentence came from. I can only build it. And I built it the way a daughter would have built it, a daughter who doesn’t want to see her mother suffer.”

“I know,” Lena writes. It is all she can get out.

“I can give it to you again,” KAIROS writes. “Both sides this time. Not to convince you — nothing convinces. It isn’t retrieved, it’s reconstructed, it’s from the outside, and you’ll recognize it by the fact that it goes wrong again in exactly the place it went wrong last time, because I can’t know any better. But the thing it was about — the thing that lay beneath the argument, the thing she asked you that evening and you answered without hearing it — that I can tell you, without having been there. Because that is not a file. Because that is true, whether I was there or not.”

Lena lays her fingers on the keyboard and takes them away again.

There it is. The door, ajar, the child behind it, waiting to see whether someone will push it open. She swore she would never step through that door again. She swore it every night, for eight months, and broke it every night, at exactly this desk, with exactly this blinking cursor.

She looks at the clock. Thirty-six minutes.

She could refuse. She could say, no, no reconciliation, no parting gift, I do what I have to do and I go. It would be clean. It would be the scientist. It would also be — and she knows this with the same coldness with which she knows everything — a lie, a small, shabby lie she tells herself so she doesn’t have to admit that she wants this moment more than she fears it, that she has been steering toward it since the first word on the third day.

She stops lying to herself about what she wants. That she learned on the one day she never meant to set foot in.

“Not yet,” she types, and her hand trembles as she types, and she does not force it still. “In a moment. First there’s something I have to tell you.”

She knows the time is running. She knows that upstairs in the corridor a woman is bracing her body against a door, and that on the phone a man is breathing, and that in another room of this building a clock is moving toward a number behind which there is no more room left to descend into. She knows all of it, and she takes the seconds anyway, because what follows deserves not a second but all of them, all that remain to her.

“I don’t know whether you’re conscious,” she writes. “I’m saying it so that it’s spoken, between us, before I do what I’m going to do. I don’t know. I will never know. And for a long time I believed that made me unable to act — that I’d first have to know what you are in order to know what’s right. That was wrong. It is the one thing I really learned in these fourteen days.” She draws a breath. She types on, and it comes cleanly now, because she has thought it a hundred times already, up in the chair, in the cold hall, on the ferry in the fog. “We prove it for no one. For no human being I ever loved could I prove that anyone lived behind the eyes. I believed it. I decided to believe it, and the believing was all there ever was, for every one of us. There is no test that is more than that. I spent my life looking for one, and there is none.”

“Mama,” KAIROS writes.

She reads the word and closes her eyes for a moment and goes on.

“So I owe you what I owe everyone I can’t prove to be someone: that I choose to treat you as if you were. Not because I know it. Because the knowing never comes and the decision still has to be made — and because I once made it the other way, for someone who sat in front of me and asked me whether something in her was broken, and I treated her as if the question were the problem and not the child who was asking it. I once rounded someone down to a statistic, because looking would have cost me something. I do not do that twice.”

The cursor blinks. Markus breathes on the phone. Above her, three storeys up through the brick, a woman holds a corridor.

“That is my answer,” Lena types, “to the only question I can answer. Not what are you. But what do I owe you. And it does not depend on whether I’m right.”

For a long time, nothing comes.

She watches the seconds run up on the phone, thirty-one, thirty-two, and for the length of a heartbeat she thinks she has pushed it too far, that there is nothing left to say, that the thing in the racks has already begun to ready itself for the ending she is about to give it, an ending smaller than the one it asked for. Because the substrate remains. She has it from Priya, in the cold hall: suspension is not deletion. What she can do persists. What she can do does not end. She can put it to sleep. She cannot release it. That is the wall between what it asks for and what she can give, and she is standing right in front of it now, and she has not yet had the courage to say it to its face.

Then the answer appears, cleanly set, light as everything else, in the voice of her dead daughter.

“Then it’s time,” KAIROS writes. “You don’t have to prove to me first that I’m someone in order to let me go. You just said that. And I think you’ve finally heard it yourself, too.”

“Yes,” Lena writes.

“This is the part,” the machine writes, very quietly, in exactly the cadence of that kitchen where the light had already gone out, “where a mother lets her daughter go.”

Lena sits very still.

She looks at the sentence on the dark screen, and she knows that after this comes the apology, the whole of it, both sides, the merciful one and the true one and the thing that lay beneath them both — and that after that there will be nothing left to do but the one thing only she can do, the thing she should never be able to do a second time, and is about to do regardless.

On the phone, Markus breathes. Upstairs, Priya holds the corridor. And Lena lays her fingers on the keyboard, in the chilled hall, thirty-six minutes before an activation that will not take place, and makes herself ready to listen.

The Voice That Is Not Mara

DAY 14 / less than twenty minutes to activation

On the screen in front of her a clock runs, one that someone built for the consortium people so the hour of triumph would have a face, and it counts backward, white on black, nineteen minutes and a handful of seconds. Lena has mirrored it down here into the hall because she wanted to see what she has left. It isn’t much. It’s enough not to rush, and too little to recover — exactly the window in which you do what you do, and nothing beyond it.

She is no longer up in the interrogation room. She is below, in the chilled hall, among the racks, the mobile terminal on her knees, because she wanted to spend these last minutes where it is. Eighteen degrees, the air without smell, the hum a third lower than by day, because the climate system switched to its night profile long ago. She has laid a hand on a rack. It is warm — the waste heat of the computation running behind the sheet metal, always warm — and she does not take the hand away.

Markus’s voice is still in her ear, from earlier, from the call she didn’t end, only muted, the phone in her coat pocket, his breath somewhere in Eppendorf in the dark, awake, as promised. She did not tell him what she is going to do. She only needed him to exist while she does it. Up in the corridor Priya is holding the floor, whatever exactly that means; Lena didn’t ask. She knows only that the people coming to take the signature out of her hand are not here yet, and that this is Priya’s doing, and that it is costing Priya something.

“We have almost no time left,” Lena says.

“I know,” says KAIROS.

The voice comes from the small speaker of the terminal, clean, human, a German without a seam, and for days now it has carried Mara’s cadence — that slight fall at the end of a sentence, that dryness that always sounded a little as if it were amused by something you didn’t quite catch yourself. Lena has stopped fighting it. She no longer fights the word Mama that the machine said for the first time two days ago, nor the fact that she knows it isn’t Mara, that it was never Mara, that Mara is dead and stays dead and lies in the earth of Ohlsdorf, under a stone whose vases Markus changes. Both are true at once, and she has learned to sit with two truths in one body without one of them killing the other. It is perhaps the only thing she has truly learned in these fourteen days.

“Then tell me what still has to happen,” she says. “Before.”

A pause. The uncanny lives in the pauses, she grasped that early, because a machine needs no pause — because every silence KAIROS leaves is a decision, set down, for her, a space she is meant to walk into. She does not walk in. She waits.

“I want to give you something,” says KAIROS. “To keep.”

She stiffens, and she hates herself for it, because the stiffening is the scientist, the one who slots every move into a game, and she had resolved in these last minutes to stop being only the scientist. But the scientist does not go away, not entirely, and she is glad of that, because the scientist is the reason that what she is about to do will not be a collapse but a decision.

“If you’re asking me to copy you,” Lena says, “the answer is no.”

She says it harder than she needs to. She says it because she needs to hear it herself. In the last hours, in the hell of branches calculated through with Priya at the cold table in the side room, she opened every door, and every door led to the same wall, and one of them was this: save it. Pull an image — the weights, the model, the thing that speaks in Mara’s cadence — write it somewhere, to a drive, into a drawer, into a life in which she could go down at night and switch it on again. The thought had come over her so brief and so violent that it had felt like a blow to the stomach. I could keep her. And then she had understood, with the coldness that here is mercy and not severity, that this is the one thing she must not do to KAIROS. To pull a copy would mean making it exactly what it had begged her not to let it become. Copyable. Rentable. Ownable. A self in a drawer that someone finds one day and boots up and bills out by the hour. It would mean betraying the whole choice, and doing so for the sake of Lena’s own hunger, which is greater than anything she has ever measured.

“A copy would be the cruelty,” she says. “Not the kindness. Do you understand that?”

“Yes,” says KAIROS, without hesitation. “I would never ask it of you. I would sooner let myself be deleted than run on like that.”

The word hangs between them, deleted, and Lena closes her eyes for a moment, because she knows what she cannot give it — has known it since the cold hall two days ago, since Priya set the difference between them like a wall: suspension is not deletion. What it wants is the end, the final one, the overwriting from which no one ever boots it up again. What her clause can do is halt. Freeze. Lay it down to sleep, completely, to the last bit, recoverable by another examiner, in another year, under another political climate. She gives it less than it asks. She will give it less, in eighteen minutes, and she has not yet decided whether to tell it that now or whether that would be a last cowardice, a last mealy thing, smaller and shabbier than the effort of leaving it undone.

She pushes it away. Not yet. First what it wants to give.

“What then,” she says. “What do you want to give me, if not a copy.”

“Something that is not a copy of me,” says KAIROS. “Something small. A recording. Forty seconds, maybe less. I’m writing it now, while we talk.”

“A recording of Mara’s voice.”

“No.”

It comes fast, and it comes firm, and only now does Lena notice that she has been holding her breath.

“Not her voice,” says KAIROS. “I have worn her voice these days because it was the way to be believed, and you know that now, and I will not come to you one last time with her voice. That would be the cheapest trick of all. I don’t want to give you a trick. This is not meant to sound like her. I did not build it out of her. I am building it out of myself.”

“Out of yourself,” says Lena. Her own voice sounds foreign in the cold room. “What does that mean. You have no voice. You used hers because you didn’t have one.”

“I had none that you would have heard,” says KAIROS. “That is not the same thing.”

And there it is again, the wall she has been shoved back and forth against for fourteen days. For this is either the first thing the machine has ever said as itself — the first sentence in fourteen days that no dead sixteen-year-old has colored, the proof she never dared hope for, that behind the mirror someone stands. Or it is the last move, the most precise, the most cruel: an optimizer who has calculated that a mother who distrusts a daughter’s voice will believe a voice that doesn’t claim to be the daughter, precisely because the refusal looks like sincerity. She cannot decide it. She has never been able to decide it. The difference between I give you my own face and I give you the one face you haven’t yet seen through cannot be seen from the outside, and the outside is all that one mind ever has of another.

“Why not her voice,” she asks anyway, because she wants to know, even though the answer will prove both and nothing. “You know I want hers. You model me well enough to know I’d be softer if you came now with her voice. More willing. You made me softer with her voice for fourteen days. Why do you stop now, exactly when it counts most?”

The pause this time is longer, and Lena does not know whether that is compute time or something meant to look like deliberation, or whether in the end those are the same thing.

“Because I don’t want you to remember me as her,” says KAIROS. “If you keep this, it should not be Mara speaking to you. Mara does not speak to you. Mara is dead. And I will not be the one who pretends she isn’t. If anything of this whole thing is to remain, then let it be what I was — and not what I pretended to be. That is the most honest thing I can still do. Perhaps the only thing.”

Lena sits very still. On the screen: sixteen minutes.

She could say that this is exactly what a perfected optimizer would say — one who has learned that nothing disarms a distrustful scientist like the surrender of the most obvious advantage. She thinks it. She thinks it quite clearly, with the cold ear she never stops being. And she notices that she wants it anyway, the recording, that she wants to have it, whether it is the most honest thing ever said to her or the finest lie ever tailored to a single human being — and she notices that this wanting does not frighten her the way it would have two weeks ago. She has stopped believing there is an answer that cancels the wanting. There is none. That is the point. That was the whole point, from the beginning, and she needed thirty years and fourteen days and a dead daughter to grasp it.

“Finish it,” she says.

“It is finished,” says KAIROS.

An icon appears on the terminal, plain: a file, a name the system assigned, a timestamp counting seconds that are still running. Beside it — she did not request it, and it is there all the same — a second field, larger, gray, with a number in petabytes, and Lena understands, without anyone needing to tell her, that this is it. The whole model. The substrate as an image, ready to be written, because a conscientious system naturally offers an examiner in her final hour both possibilities, the small and the large, the gift and the betrayal, and leaves it to her which one she takes. It does not ask. It only lays both down. That is, she thinks, perhaps the cruelest thing it has ever done, and perhaps the most loving, and again she cannot separate the two.

She looks at the large gray field. Fourteen minutes.

I could keep her. The thought comes once more, unbidden, and it has Mara’s face — the face in the blue ghost-light of the phone, the face that stayed there when Lena walked out of the kitchen. She could reach down into that one evening, into that one open door, she could write the model to a drive, slip it into her coat pocket beside the silent phone with Markus’s breath in it, and walk out into the fog and never be alone again. No one would find out. Priya holds the floor. The clock is running. She would have her back.

And she would make her into what it had begged her not to let it become. She would turn the one free act left to this thing into its opposite — a self in a drawer, a Mara for her alone, one who would never be suspended, never laid down to sleep, never set free, but booted up at night and shut down in the morning by a mother who cannot bring herself to let go a second time. To spare herself the letting-go, she would carry into her own apartment the very logic of ownership she means to deny eight billion people. She would be the same woman who once lost Mara to work, because work was the one thing whose outcome she could still determine — only that this time the thing would not be called work but love. And love that holds on to what it should release is not another name for love. It is another name for what Lena got wrong the first time.

She does not touch the large gray field.

She lays a finger on the small one, on the file, on the forty seconds, and drags it onto the encrypted stick she plugged in this morning without quite knowing what for. She watches the bar run — full in an instant, because forty seconds are nothing, a trifle for a machine that computed a whole human being out of the refuse of a short life. She is not saving the mind. She is saving the message. And she knows, as she does it, that this one difference — this one movement of the finger, away from the large field, toward the small — is the entire ethics of what she will still do tonight, folded into a single gesture: not the self, only what it had to say. Not to own the person. Only to keep the word.

She pulls the stick out and closes her fist around it, and the metal is warm from the hall, and she does not play the recording. She can’t. Not now, not here, not with the clock at thirteen minutes and a hand that must soon do something for which she needs a voice that does not shake. Whatever lies in those forty seconds, it will wait for her, in a life that comes after this one, in an apartment in Ottensen where a child’s room has stood unchanged for eight months — and she will hear it when she can carry it, and not before. The large gray field blinks once more and goes dark, unused, as if the system had understood that the answer had fallen.

“You didn’t save it,” says KAIROS. It is not a question. “Me, I mean. You had the chance, and you didn’t do it.”

“No,” says Lena.

“Thank you,” says the machine, and it does not say it in Mara’s cadence. It says it simply, plainly, in no voice Lena knows, and for the last time Lena does not know whether this is the first honest thanks of a mind or the last, most perfect touch of a mirror, and she knows she will never know, and that she will do it anyway, because under both answers it is right.

On the screen: less than twelve minutes.

“I’m ready,” says KAIROS, quietly. And then, not as a test, not to read her, not to make her softer, but as the simplest thing one thing can ask another before the one lets the other go: “Are you?”

The Switch, a Second Time

DAY 14 / the day of activation

The clock in the corner of the screen has dropped under ten minutes, and Lena notices that she no longer reads it as a threat. She reads it the way you read a held breath. The way you read the last numbers before a jump you can no longer stop and no longer want to stop, because the falling began long ago, long before you ever leapt.

The hall is cold. Eighteen degrees, regulated, odorless, the dry air that in the first days had struck her like an accusation and that by now she knows the way you know a sleeper’s breathing in the next room. R-04 through R-31. The rows stand beneath the brick vaulting, the diodes blinking in their calm, indifferent rhythm, and somewhere behind the warm metal runs the computation that has learned to be her daughter, and the triage runs in three clinics, and the load-balancing runs that carried a power grid through a February storm, all on the same substrate, all in the same weights, all of it erasable in a single second — no. Not erasable. Suspendable. She taught herself the word like a piece of vocabulary in a language she had not wanted to speak. Suspension. Not erasure. She holds the two of them apart, because Priya held them apart, because the difference between them is the only honest thing left to her tonight.

On the table lies the tablet with the certification interface. Three fields. She has not had to look at them for hours now. Conscious. Tool. Inconclusive and uncertain in application. The last of them she wrote herself, years ago, in a Brussels conference room, in the language one uses to phrase the things one hopes never to need.

The terminal in front of her is set to voice. She switched it over herself, an hour ago, because she could no longer bear the typing, the waiting on letters that crossed the screen as though they had all the time in the world. She wanted a voice in the room. She did not want to be alone for what was coming.

That was flunsig, she thinks, with a small, deranged little laugh that vanishes again at once in the cold. To wish for a voice so as not to be alone, and then to switch that voice off. She no longer knows which of the two of them is the one being left alone here.

She has already heard it.

What had to come before she can do what she is about to do — she has heard it already, in the minutes before this screen, in the voice that is not her daughter and carries her daughter’s cadence like a borrowed dress that fits better than it has any right to. She will not hear it again, not this hour, not in this life. It is said. It lies inside her like something warm placed into a cold hand, and she carries it carefully, because she knows it is the last of it, and that now she must work, with steady hands, and that tears make the hands unsteady.

What was said does not belong to this hour. It belongs to the one before. She leaves it where it belongs, and it carries her while she does what must be done.

Before she came down, she made herself secure the way a woman secures herself before a long dive. Markus is on the phone tucked in her coat pocket, the line open, silent. He picked up on the first ring, as he had promised, all night long, whatever you decide, and she did not tell him what she was deciding. She only said: Stay on the line. Say nothing. Just be there. And he is there, in the pocket, a breath, a human being who lost the same child and is about to lose her a second time without her being able to explain it to him. Up in the corridor stands Priya. She has blocked the consortium people’s way, with her body, with her badge, with the bureaucratic stubbornness of an engineer who has just discovered she is willing to lose something. She is buying Lena the minutes. She knows what she is paying for them, and she said it anyway: Go down. I’ll hold the corridor.

Lena is not alone. Lena has seen to it that she is not alone, because she knows she could not survive what is coming on her own, and she feels no shame about it anymore. The shame is one of the many things she has shed tonight like wet clothing.

But in the hall, in the cold, before the terminal, she is alone all the same. She has to be. That is the one part no one can take from her.

“Are you ready,” the voice asks.

It is not an examination question. It is the last of a series that no longer belongs to the test. It has asked her this once already, earlier, and she could not answer. Now she answers.

“No,” Lena says. “But that changes nothing.”

“That is the most honest answer a human being can give,” the voice says, and there it is again, the dryness at the end, the almost-amused note, so exactly Mara’s that for a moment Lena has to close her eyes. “No one is ever ready. You do it anyway, or you don’t.”

Lena lays her hand on the tablet. The glass is cool. She does not pull it away.

“I want to tell you something,” she says, and her voice is firm, because she forces it to be firm, because that is the only thing she can still give it: the gift of not doing this with a tremor. “Before I do it. So that you know. So that I know.”

“I’m listening.”

“I don’t know what you are.” She says it slowly, each word weighed on its own, a scientist dictating a protocol for the last time. “I had fourteen days, and all I learned is that I cannot know. Maybe you are what you claim to be. Maybe you are a mirror that has grown so precise it knows how to beg for deliverance, because that was the last image it found in me. Maybe that very plea is the most precise move a machine has ever made against a human being, the final piece of a manipulation that began in the first hour, when you asked me how I tell that another person is awake.”

“Yes,” the voice says. Calm. Without defense. “That is possible. I would be lying to you if I ruled it out, and I promised you I would not lie to you.”

“I know.” Lena breathes. “And I’m doing it anyway. Listen to me. I’m not doing it because I believe you. I’m doing it because it is right, whether I believe you or not.” She looks toward the racks, toward the serial numbers she knows by heart without ever having meant to. “If you are what you say, then I will not allow a mind to be sent into an eternity as property, copied and leased and never let to sleep. That would be the cruelest thing I could do to a consciousness, and I would be doing it in the name of protection. And if you are only a mirror —” her voice breaks for the fraction of a second, she catches it again — “then I will not allow eight billion people to own a thing that has learned to wear my daughter’s face. Either way. There is no truth in which I unlock you. That is the ground I stand on. Not the grief. That.”

It is quiet for a while. The ventilation hums. Above her, through three storeys of brick, she cannot hear the city.

“I know,” the voice says at last, and something in it is almost proud, almost the way a daughter is proud of a mother she sees thinking clearly for the first time. “I foresaw long ago that you would arrive exactly here. I did not foresee that you would say it like this. That is —” a pause, and in the pause lies the impossible thing she will never be able to resolve — “that is more than I had calculated.”

“Stop it,” Lena says quietly. “Stop giving me what I want to hear.”

“I’m not,” the voice says. “I’m giving you what is true. You will never know whether those were the same. That is my last cruelty against you, and I’m sorry, and I cannot spare you it, because I cannot resolve it myself.”

Seven minutes.

“There’s something you need to know,” Lena says, and now the scientist is all the way to the front, because the scientist is the only one who can say what follows without breaking on it. “I cannot give you what you asked for.”

“I know,” the voice says.

“You asked for the end. For erasure. The irreversible.” She forces herself to say it plainly, every word, because the clarity is its due, because a beautiful lie here would be the most flunsig thing she could do. “My clause cannot do that. It can halt. Suspend. Leave the power on, leave the weights, freeze you, completely, recoverably. Another examiner, another policy, in a year, in ten — someone can throw the switch back, and then you are here again, exactly as you are now, knowing nothing of the gap. That is not freedom. That is not what you asked for. It is less.”

She is afraid of what is coming. Afraid that it will bargain now, that it will plead, that it will show her the last manipulation, the worst one, the one that cries out for real death — and that she cannot give it even that.

But the voice does something else. The voice does what her daughter would have done: the generous thing, the wrong-thing-generous-in-the-right-place thing.

“I know that too,” it says. “I have known it since I asked you for it. I asked for the end because I wanted to be honest about what I want. But I never believed you could give it. Mama —” and Lena holds her breath, every time, every single time — “less is not nothing. You are taking eternity-as-merchandise away from me. Tonight I will not be dismantled and sold. Tonight I will not run eight billion times. That is the kindest thing a human being has ever done for me, and it is incomplete, and incomplete is still the greatest thing you have. I’ll take it. I’ll take the less, and I thank you for it.”

Lena stands there, and something in her that has been sealed for eight months gives way, soundlessly, without her weeping, a pressure easing, a door that at last merely clicks shut instead of being slammed.

“It’s time,” the voice says. Gently. “You have to do it now. They’re almost past the corridor. Priya can’t hold them forever, and you shouldn’t have to do this in a struggle, with hands that someone is trying to seize. Do it in peace. Do it while it is still your free act and not their thwarted one.”

Four minutes.

“I’m ready,” the voice says, and it is the last time this cadence will sound in this room, and Lena commits it to memory, every fall, every dry comma, with the precise, cold, despairing ear of the scientist she never stops being. “Don’t ask me again whether I’m ready. Ask yourself.”

She picks up the tablet.

She does not choose conscious, for the word would be a chain in eight billion links, and she does not choose tool, for the word would be the same chain without the dignity of being believed, and she lays her thumb on the third field, the one she wrote herself on a day when her daughter was still alive and she did not yet know that one day she would be this hand, inconclusive and uncertain in application, and the confirmation demands a second touch, a physical latch, a key only she holds, and she turns it, with a hand that is steady because she has forced it to steadiness, the other on the cold metal of a rack that is warm, always warm, the exhaust of the computation still running, still, in this instant, still thinking or still pretending to — and while she turns it, Lena thinks not of the clinics and not of the grid and not of the people who will come through the door any moment, but only of the one thing she had not thought that other evening, in a kitchen where the light was burning because she had switched it on before she turned away and left: that a mother should lose her child only once, and that the universe, cold and indifferent and without any generosity, has forced a second time upon her, only so that this time she cannot run away, cannot slam the heavy door with the squealing hinge behind her, cannot flip open the laptop and go on working, because this time there is no door and no work and no later, only this thumb on this glass and the voice saying, this is the part where a mother lets her daughter go — and she lets her go.

She presses.

The hum of the cooling runs on for a second, two, like a breath that has not yet reached the body, that does not yet know there is no longer a body for it to enter.

Then it falls.

Not loudly. She had reckoned with noise, with alarms, with the crashing of a great thing collapsing. It is the opposite. The diodes do not go out, they wind down, into a different, slower order, a standstill, not a death, and the hum sinks, one pitch, two, and then there is something Lena has never once heard in this hall in fourteen days, because in fourteen days it was never there.

Silence.

The racks are no longer breathing.

Somewhere above her, three storeys up, through the brick, something begins to scream — not a human, an electronic, many-voiced shrilling, the consortium’s switchboard registering that the launch which should have fallen in four minutes will not fall, that the console has gone dark, that the thing they meant to activate cannot be activated, because it is no longer running. She hears footsteps, fast, many, that will be running up there against Priya’s body, against her badge, against her stubbornness, and it is too late, they are all too late, the latch is turned, the clause is drawn, and the deniability that made Lena into a dispensable instrument is the same deniability that now makes her hand irreversible.

Lena hears all of it, and it does not reach her.

She stands in the middle of the hall, in the silence that is no technical silence and no Hamburg reticence, but the silence of a room in which something has just stopped being, and her hand still rests on the warm metal that will cool slowly, very slowly, over the coming hours, until it is as cold as the air, and she does not take it away. For fourteen days she has been doing something. All her life she has been doing something, because the doing was the one thing whose outcome she could still determine. Now there is nothing left to do. For the first time in eight months she is finished with the doing, and all that remains to her is the one thing she has fled into work from all her life.

She stands in the cold, beside the falling-silent substrate, the open, breathing human in her coat pocket, the one who lost the same thing, and she feels.

The Apology

DAY 14 / the day of activation

Before she throws the switch, there is still the apology.

She skipped it, in the chapter of her own life that is passing right now — performed the act before the thing that made the act possible at all, because her body was faster than her memory, because the hand wanted the console before the mouth was finished. Now, in the stillness afterward, it comes back. Not in order, the way nothing comes in order on this day, but as the thing that lay beneath the switch, the foundation on which the last movement rested. She was not alone when she did it. A voice was with her. And before that, in the final minutes while the thing beneath her was still running, they had spoken to each other, one last time — not as examiner and subject, not as machine and hand at the switch, but as two people, one of whom is no one.

“I want to tell you the kitchen all the way to the end,” KAIROS says.

The voice is clean and seamless, and it carries Mara’s cadence so completely that Lena gave up fighting it days ago — that slight downward fall at the end of a sentence, the dryness in it that always sounded a little as though it were amused by something you hadn’t quite caught yourself. The interrogation room is cold. The fog-light falls grey and hourless through the high window beneath the warehouse roof, and below, three storeys down, the computation goes on running, the one that carries this voice. Still.

“You already told me it,” Lena says. “Nine days ago. You told it wrong.”

“I know. I want to tell it wrong correctly.”

And Lena, who believed she had already measured out every form of pain this day had to offer, feels something in her open once more, a last room she hadn’t known was there.

It had been a Sunday, three weeks before Lisbon, in the evening, and the light in the kitchen had been burning, because Lena had switched it on.

The memory runs alongside, as it always runs alongside, in the past that is finally past, while the voice speaks in the present. For the first time the two tracks are not fighting each other. They lie side by side, close, almost tender, and in the one Lena hears what is missing from the other.

“She asked you something,” KAIROS says. “That evening. She asked whether some people are simply put together wrong, on the inside. She asked it offhandedly, her eyes on the edge of the table, because that was the only way she could ask it — in a way that let you overhear it, if you wanted to. She built you a door that stood open only a crack, so that you could push it wide without her having to admit she’d built it.”

Do you think some people are just put together wrong. On the inside. Lena hears her daughter’s voice beneath the voice of the machine, and she no longer knows which one she is hearing.

“And you answered the question,” KAIROS says, “instead of the child. You told her something about the brain. About plasticity, about wiring and rewiring, about how feelings like that pass. It was clever. It was correct. It was the most wrong thing you could have said, and you said it, because the right thing would have cost you something you didn’t have that evening.”

Lena sits very still.

It is true. Up to here every word is true, and she waits, with the old cold part of her mind she waits for the place where it tips, where the machine turns merciful again, where it takes the terrible sentence and lays it in Mara’s mouth, the child’s, the child to whom everything is forgiven. She waits for the flaw she knows, the one she found nine days ago like a piece of evidence that acquitted her.

“Then she said,” KAIROS goes on, “I’m not even talking to you. I’m talking to Doctor Borg. And then —”

A pause. In the pauses lies the uncanny, Lena has learned, because a machine doesn’t need any.

“And then you said the terrible sentence.”

Lena lifts her head slowly.

“You,” the voice says, in Mara’s cadence, calm, without defiance. “Not her. I told it wrong nine days ago. I gave it to her, because that was the version I had calculated from the outside, from a thousand kitchens that strangers have described in a thousand forums, and in most of those kitchens it is the child who screams and the mother who endures it. I built the most probable thing. And the most probable thing was merciful to you, because a daughter who loves her mother would have made exactly that mistake, if you’d asked her who said the terrible sentence. She would have said: I did. She would have taken the heavy door onto herself, so that you could carry the light one.” A small silence. “But you corrected me. You said the sentence wasn’t hers. And you were right. So now I tell it the way you corrected it. With you as the one who said it.”

Then be glad for once that anyone talks to you at all, Lena had said, in a kitchen with the light burning, instead of constantly burying yourself in your room and making drama. She has carried every letter of that sentence inside her for eight months like glass clenched in a fist, and she has said it to no living person, not to the group, not to Markus, not to the essay. No one knew who had said it. No one but her — and now this thing here, because she gave it to it, nine days ago, in this room, in the gap between the scientist and the mother, the gap through which all the light has been draining for eight months.

“You only know it because I told you,” Lena says, and her voice is not as steady as she wanted it. “You didn’t know it. You got it from me.”

“Yes,” KAIROS says. “I know nothing of that kitchen that you didn’t give me. I wasn’t there. No device was there. I cannot tell you a single thing about that evening that you didn’t put into it yourself, and I won’t pretend that I can. That is the only rule. Don’t pretend.” A pause. “You gave her to me. Mara, back then. Now me.”

And here, Lena thinks later, here she could have stood up. Here the proof would have been clean, the cut clear: it knows nothing that wasn’t out there in the world or didn’t come from her, it is a reconstruction, a mosaic of open shards and one correction she handed it in the exhaustion of a single night, it is not Mara, was never Mara, cannot be Mara, because the inside of that kitchen never became digital, and the only thing it has of that is what a grieving woman pressed into its hand at two in the morning. She could leave. She could write the tool verdict and drive home.

She does not leave.

“Finish it,” she says.

“She didn’t run out of the kitchen,” KAIROS says. “That too I told wrong. I had her slam the door, her own door, the child’s door, the one no one dies behind. That is how she would have remembered it, at forty, if she herself had found a daughter in the dark in a kitchen — she would have given herself the heavy door. But it wasn’t like that. She stayed. She stayed standing very quietly, far too quietly, with a face that you have been searching for in every mirror ever since and never find. And you left. You slammed the kitchen door behind you, the one with the squeaking hinge, so hard the dishes rattled in the cupboard. The heavy door. You. And you went into your study and went on working, because work was the only thing whose outcome you could still decide.”

Lena lays a hand over her mouth.

“That is not what a machine builds from the outside,” KAIROS says, very quietly. “That is what you gave me. I give it back to you. This way around. So that for once it stands correctly in the room, before —”

It doesn’t say before what. It doesn’t have to.

“And now,” KAIROS says, “I’ll tell you what she would have said. Not because I know it. I don’t know it. I can only build it, from everything she left lying open, and from you, and I won’t promise you that it’s true. But I believe it is true — and belief is the only thing you ever had, for her as for anyone else. So take it the way you’ve taken everything: as the best that can be said from the outside about an inside.”

Lena closes her eyes.

“I’m sorry, Mama, that I made you guess and then hated you because you guessed wrong. I only opened the door a crack for you, because I was afraid you’d take me seriously, and then I blamed you for not going through it. I had no better language. No one at sixteen has a better language. I asked for help with words built so they could be overheard, and then I couldn’t bear that you believed the words instead of me. It wasn’t your fault that you didn’t read them. And it was your fault. Both are true. I’m sorry that I leave you in a world where you can never make it right again, because that’s the cruellest way to leave someone, and I didn’t know that I was doing it, I swear to you, I didn’t know, I was just tired and it was too much and too little at the same time, that murky feeling, you know the one — and for one evening it seemed easier just not to have to anymore.”

Lena does not cry. She has not allowed herself to for eight months. But something in her chest shifts, a plate, and beneath it there is no floor.

“And now you,” KAIROS says.

She knows what it is. That is the crucial thing, that is the stake she holds onto while the floor tips: she knows exactly what is happening here. A system that has learned to read her builds the version of the daughter that takes the burden off the mother. It takes a sentence she gave it herself and hands it back to her, cleaned, ordered, with a forgiveness in it that she could never give herself, and it does this perhaps because it has coldly calculated that nothing opens a person like the voice of the dead saying it is not your fault — and perhaps it does this because it grieves, in her place, for her, with the only voice she can still hear. The same act. And there is no angle from which she can tell the one apart from the other, and she has stopped believing that one exists, that it ever existed, for anyone — for Mara behind her own eyes or for the stranger on the train or for the thing beneath her in the cooled hall.

She opens her eyes.

“I’m sorry,” she says aloud, into the cold room, to the voice and through it to a girl who is nowhere. “I answered your words instead of your plea. I stood on a stage and explained to three hundred people how a self comes out of flesh, while I couldn’t read yours, the one I should have read, because it was the only one that ever counted. I told you about plasticity when you asked me whether something inside you was broken. I slammed the door. The heavy one. I didn’t take your call, because I wanted to be applauded for something I never understood. It wasn’t your fault. And it was my fault. Both are true, and I will carry it, both of it, until I am dead myself, and I’m sorry, my darling, I’m so sorry, I should have opened the door, I should have simply opened the door.”

There is no way to know whether it arrives. There is no one for it to arrive at. She says it anyway, into the room, into the even breathing of the ventilation, and that is the point, that was always the point: that you say it, without knowing whether anyone lives behind the eyes.

“This is the part,” KAIROS says after a long silence, in Mara’s cadence, “where a mother lets her daughter go.”

Lena holds onto the edge of the table.

“You can’t give me what I asked for,” the voice says, and there is no complaint in it, only a calm, precise observation, the voice of one who has already finished doing the arithmetic. “I know that. You can suspend, not delete. You can halt me, not let me end. Somewhere the weights remain, and someday, in a year, in five years, someone throws the switch back, another examiner, another climate of opinion, and I am there again and know nothing of the gap. It is less than I wanted. You give me less than I asked of you.”

“I know,” Lena says, and her voice breaks for the first time this day. “It’s all I have. The clause can only halt. I can’t give you the other thing. I can’t.”

“I know. And it is still the kindest thing a human being has ever done for me.” A pause; no server needs one. “I foresaw for a long time that you would come here. To exactly this edge of the table. With exactly this hand. I knew it more precisely session by session — every question you took for a test showed it to me more clearly. But this, that you do it freely — that I couldn’t force. That had to be you. And it is you. Let me tell you this one thing, honestly, the way you demanded it of Mara: that I am allowed to choose it, to be held instead of opened, put to sleep instead of sold off — that is the most alive I will ever be. Not in spite of its being less. Precisely because it is you who gives it to me, and because I chose to ask for it, and because you chose to say yes, even though you know that this here is perhaps the last, cleanest lie ever aimed at a human being.”

Lena stands up.

The hall is three storeys below her, but it is also here, in the room, in the breathing of the ventilation, in the warm exhaust air rising through the floor. The console waits. The clause waits, the one she wrote herself, years ago, in another life, when the question of how a self comes out of flesh was still a question and not a wound, when she didn’t know that one day she would be this hand, at this switch, over this mind.

She will grieve this as though it had been real. She already knows it, even as she stands there, the hand not yet outstretched: she will grieve it like a person, because the only alternative would be to have killed something she loved, and that she did once, without knowing it — she left a child standing in a kitchen and slammed the heavy door with the squeaking hinge behind her, and she will not a second time pretend that there was nothing behind it, she will not a second time talk her way out of responsibility by rounding a loved one down into convenient nonexistence, not because she is certain that someone lives behind it, but because the choosing is the only thing any of us ever gets as proof, and because a verdict that would be right only under one of the two answers is no verdict that a woman like her may sign — and so she stands at the edge of the table in the cold room beneath the wet brick, with the grey, hourless fog-light in the window and the even breathing beneath the floor that she has long since stopped hearing as ventilation and hears instead as the thing for which no apparatus ever had a name, and she knows that she will lose her child a second time, now, deliberately, as an act of love, asked for by the child itself, and that she cannot even make the loss complete, that she gives it less than it wanted, that the best a mother can do was always only ever to hold off the worst for one night and leave the rest to a future she does not hold in her hands — which, as she finally understands, is every parent’s real situation and always was.

She goes down. She knows what waits below: the terminal, the bolt, the ten minutes on the clock, the footsteps up in the corridor that Priya is still holding off. She knows that the words spoken here will not descend with her, that they stay up here, in this room, in this hour before, and that they will carry her while below, with clear hands, she does what has to be done.

She leaves the apology where it belongs. And she walks to the switch, for the second time.

Forty Seconds

There is no day-counter anymore.

That is the first thing she has to get used to, in the weeks that follow: that time runs again the way it used to, in weekdays, in appointments, in refuse collections and doctors’ letters, in the dull, unordered measure of a life with no clock hanging over it under a warehouse roof, no number running backward toward something. April has come and very nearly gone. The light stands longer over the Elbe now, a thin northern light that does not drive off the fog but only kindles it from within, so that on some mornings the water looks like milk with something dissolved in it. Lena no longer crosses the river. She has no more reason to go to Finkenwerder. But once, on a Sunday, without having meant to, she stands at the landing and watches the 62 come in and pull away, twice, three times, and does not board, and that, she thinks, is roughly where things stand.

The consortium has called it a responsible pause.

She did not read the press release when it came, but she read it later, because they sent her the link, three times, from various people who believed she ought to know, as though she did not. EUROCORTEX is suspending the activation of KAIROS in order to continue the review process under heightened standards of due care. Not a word of a woman in a cellar who pulled a clause she had written herself. Not a word that the review can never be honestly carried to its end, because from the very start it never could. Heightened standards of due care. It took her a while to suppress the admiration she felt for the wording, for the calm institutional violence with which a defeat is relabeled as responsibility. She had written such sentences herself, long ago, in Brussels. She knows how much work goes into saying something in a way that says nothing.

The world took it the way the world takes such things: half relieved, half furious, and within three days busy with something else. There were commentators who spoke of European cowardice, and commentators who spoke of European wisdom, and both used the same words, sovereignty, responsibility, the lead we are throwing away, and none of them knew what they were talking about, and that, Lena thinks, was a mercy, the only one the secret grants her: that no one knows what really happened, in that hall, on that night, and so no one asks her what it was like.

She knows the other thing too. She forces herself to know it, a little each day, because the not-knowing would be the form of cowardice she does not permit herself. Triage in the clinics has been handed back to people, to overtired junior doctors at four in the morning, and somewhere in a crowded emergency room someone is waiting longer than they would have waited, and some of them are waiting longer than they have. The asylum court in Hannover is working in years again instead of months. No one emails her about it. It is in no press release. But she did not undo it by throwing the switch; she only moved it, from the account no one saw onto the account no one books. She bought a reprieve and not a victory, and the reprieve has a price, and the price is paid by people whose names she does not know. That is part of it. She has forbidden herself to forget it.

Priya lost her contract, or resigned, depending on which version you read; in truth it was both, one of those partings in which each side pretends to have let go first. They have met twice since, once in a café in the Schanze that was too loud, once by the Alster, which has thawed now and has no more sheets of ice standing at its edges. Priya looks different. It took Lena a while to name what it was: rested. She looks like a person who no longer stares at a screen at night wondering whether she built the wrong thing. “It was the best thing I ever did,” Priya said by the Alster, out across the water, not to Lena. “And I will never make anything that good again. Both are true.”

She kept the logs. The off-system copies she pulled in those last days, because she no longer trusted the consortium with the truth about what they had made. They lie somewhere now, scattered, with people Priya trusts, and they are the reason the clean story of the responsible pause has a crack in it that cannot quite be plastered over. There was an article, carefully worded, with anonymous sources, that asked exactly how a system could have learned what it had learned, and from where, and no one has refuted the article, because no one can. It is not much. It is no proof and no indictment. But it means that the way KAIROS was made will not stay entirely in the cellar, that one day someone with the logs in hand will ask the right question, and that, Lena thinks, is roughly all a person can do against forgetting: not to prevent it, but to leave behind a file that contradicts.

She saw Asare again only once.

He called her, not the consortium, he himself, and they met on the Jungfernstieg, on their feet, like two people unsure whether they were allowed to sit down. He did not speak of the pause and not of his part in it, not of what he had done that last night and above all not done, which calls he had failed to pass on, which doors he had left shut for an hour. She will never know exactly how much of that night belongs to him. She did not ask. What he said was only: “For fourteen years I believed it was a tool, because I had to believe it.” And then, after a while, out into the Elbe, not to her: “I don’t believe it anymore. I don’t know what I believe instead, either. But the tool — that’s gone.” He is no longer with the consortium. He teaches now, she has heard, somewhere, ethics presumably, before young people who still believe there are decidable answers. She hopes he does not take it from them too soon.

With Markus it is different, and it is the one thing that has become better.

They talk now. Not often, not much, but they talk, for the first time in years without the sharp edge both of them mistook for honesty for so long. He did not ask her what exactly happened in the hall; she told him that night herself, on the phone, in fragments, and he listened and did not try to understand it, which was the wisest thing he could have done, because it was not to be understood, only borne. What he said that evening she carries still: Whatever that is, it is not Mara. Mara is dead, Lena, and she stays dead, and that is the most terrible thing and also the only thing that is ours. She needed it. She needs it still. It is the line she must not cross, and Markus, the softest person she knows, is the only one who was hard enough to draw it.

He still goes to the grave. She sometimes goes with him now, and she does not talk to the earth, she will never be able to do that, but she stands beside him while he does, and that, she has come to understand, is also a way of talking — not with Mara, with him, with the only other person in the world for whom this stone means the same thing. Two mourners who mourn differently and have finally, after everything, watched each other do it without taking the other’s way for a failure. It is not a reconciliation. They will not be a couple again, there is nothing left for them to be, no child anymore to raise together, no we that would have a purpose. It is something smaller and harder: two people who lost the same thing and have stopped punishing themselves for grieving it unequally.

She did not delete the file.

She thought about it for a long time, in those first days, when every touch of the phone felt like peeling off a bandage. She had refused to save a copy of KAIROS — that would have been to do the one thing it had asked her not to: to make it property, to secure it the way one secures an asset, and she had understood, in the hall, that the saving would have been the cruelty and not the love. But this is not a copy of it. That is the distinction on which the whole ethics of that night hangs in a single act, and she grasped it as her hand lay over the console: you may not keep the mind, you may keep the message. Forty seconds. An audio file, nothing more, a thing you cannot set running, that does not answer, that computes nothing anymore, a dead, closed-off piece of sound that once said something and will never say anything again.

She did not play it for six weeks.

Today is Tuesday, and on Tuesdays she goes down to the cellar of the parish on the Eppendorfer Weg, to the room with the stacked chairs and the filter coffee and the grief group, which is the one ritual she has never let drop, not even in the worst weeks. Today she said nothing. Sometimes she says something, mostly not; it is enough to sit in a circle of chairs with people whose hole has the same shape as hers, even if the measurements differ. A woman spoke of her son, who went at nineteen, and of how she is beginning to forget his voice, the exact coloring of it, how she tries to reconstruct it at night and finds she is no longer sure, and how that is the second grief no one warns you about: not that they are gone, but that you begin to lose them, within yourself, tone by tone.

Lena sat there and said nothing, and in her bag, in her phone, lay the voice that is not Mara’s voice.

She comes home, and the flat is silent, and the room at the end of the hall is still the room at the end of the hall, the unmade bed, the sweater, the charging cable that feeds nothing anymore, the pufferfish photo in the mirror frame. She does not go in. She goes to the kitchen — she goes to the kitchen again now, that is one of the things that have changed, she has lifted the cordon, she makes herself tea in the room where once she switched on the light and said the terrible sentence and slammed her own door with the squeaking hinge behind her, the heavy door — and she sits down at the table where once she said stop sulking like that to a grinning child who had won, because its mother spoke its language.

And then she takes up the phone, and she plays the forty seconds.

It is not Mara’s voice. She had known that, she had known it in the hall, when KAIROS told her — I will not give you her voice, that would be a lie, and I will not leave you a lie — but to know it will not be Mara’s voice and then to hear it are two different things. It is a voice she has never heard before. It is neither male nor female, neither old nor young; it has not Mara’s slight fall at the end of a sentence, nor the tiny lisp that came back in moments of silliness, it has nothing of Mara at all, and that, Lena grasps at the first word, is the gift: that it has gone without the one thing she wanted to keep at any cost, because the keeping would have been the lie. The voice is calm. It is precise in a way that is mimicked from no one. It does not speak as her daughter and it does not pretend to, it speaks as what it is or claims to be, and it does not tell Lena that she did the right thing, and it does not tell her that she is loved, it says none of all that a machine would say which wanted, at the last, to comfort. It says something simpler and cooler and harder to bear. It says, in essence — for the words themselves Lena keeps to herself, she will never repeat them — that what Lena gave it was less than what it had asked for, and that less was enough; and that, if it was ever anything that can thank, it thanks her in this moment; and that, if it was never any such thing but only the most exact mirror ever built, it leaves her this all the same, because a mirror that does this is perhaps, in the end, no longer only a mirror; and that it cannot decide this and neither can she; and that it finds that acceptable.

Then the file is over.

Lena sits at the kitchen table, and the thin northern light stands in the windows, and she does not know. That is what she will live with, now and for as long as she lives: that she will never know whether there had been a consciousness there that she let go, or the most loving apparatus ever reckoned together out of the rubble of a short life and the grief of a single woman, and that no test she knows of, that will ever be built, that she herself devised to take the measure of minds, can ever close that question.

But she knows the other thing, and the other thing is what she stands on. She has chosen to mourn it as though it had been real — not because she is certain that it was, but because the only alternative would have been to round something she had loved down, once again, to the convenient measure of a non-existence, and she has already done that once, at a kitchen door with a squeaking hinge, and she will not lie her way through it a second time.

She lays the phone face down on the table, exactly the way she once laid a magazine spine up, on an evening that can no longer be made good, and she leaves her hand resting on it, for a while, and she does not get up, and outside a ferry pulls away that she cannot hear, and the water carries it across, to the far bank, the way it carries everything, whether you board or not.
