Julian date 2459656, day one hundred and one, Saturday, eight a.m. Beijing time.
The spectrum did not come back all at once. Some countries held to the exact hour, some came back eight hours early, and some stations had scattered for good during the Silence. Hu Yisu counted lines as always. By eleven a.m. the number on the whiteboard was one hundred ninety-one.
Before the shutdown on day one, that number had been two hundred seventeen.
He paged back through his own records, checked line against line, and worked out who the twenty-six missing ones were. At the end he wrote a frequency in the corner of the whiteboard: 94.7. The local traffic station's slot had come back as navigation data—the frequency point had been rented out. No obituary. The frequency table just carried a new line where the old one used to be.
The stations that resumed broadcast opened with all sorts of first sentences. Some read out a clause of the protocol. Some played the national anthem, and in the empty seconds before the music you could hear the fader being pushed up. At one station the host's first sentence was: that stretch just now wasn't me who killed the mic. Someone had recorded the last hour of black frequency, cut it into a hundred-minute album, and put it up for sale online at nine ninety. The first comment asked: what's in it. The second replied: nothing. That's what.
She computed S at ten. Line one hundred one, 0.37. Line one hundred two, 0.37.
Mateo's email had arrived in the morning, half a day later than his usual Monday report, one line: a hundred days, I listened to the full hundred. Four blank lines below it, then one more sentence: the first spectrum lines are already coming back on this side. Where are yours.
She replied: one hundred ninety-one, as of yesterday. He sent back a number: sixty-four. She understood—his hemisphere had never had much to turn off in the first place.
The Long Night framework's hundred-day assessment report came out in draft. The concluding paragraph, first version, read: no significant change observed during the Silence.
Observer Guan insisted on that wording. He attached a statistical note: single point 0.37, baseline 0.34, error plus or minus 0.03, within one standard deviation; 0.36 had occurred once in a hundred days; the trend test was not significant. That, he said, was called science.
The Wake faction's three representatives sent back three versions of the same sentence: then release all hundred numbers and let the public see the nonsignificance for themselves. Observer Guan replied: the precondition for release is that the data can withstand being looked at.
That sentence hung in the group overnight. The next morning Director Cao of Nanshan sent a document to the framework secretariat, copied to every participating unit. Title: Inquiry into the Credibility of the Hundred-Day S Series, in Twelve Points.
Twelve points. Zhou Yan read down them one by one.
The S series was kept by a single person on paper forms, with no version control; the estimator had been refused replacement on the verbal instruction of someone who declined to sign any document; Bonn had twice requested the high-resolution data, and both answers had been not yet; the internal memo's sharing table had eleven rows, of which two remained blank to this day; one key amplitude dataset had been delivered a day later than a colleague's—her side 603, theirs 903; the source of the leaked meeting video had never been found, one page of meeting materials was missing, and the leak had objectively advanced the passage of the Silence resolution; the situation report to the supervising bodies ran forty-seven characters in full and contained two instances of the phrase "high attention"; the hundredth line had been computed and released by the party herself, alone, within the forty minutes before it was copied to everyone, with no second person checking at any point.
The twelve charges had been written down along the grain of her habits, like footprints traced from one person's gait, every step one she had taken herself. She finished reading and could not find a false one among them. That was the worst of it: they needed no rumors. They needed only excerpts.
The second half of the inquiry quoted Lu Weiming's letter. Quoted his original words: this is everyone's illness, not your discovery. Then it continued: since a colleague had long since pointed out the nonindividual nature of this result, the procedural legitimacy of a core criterion of a global experiment being held and computed by a single person was open to question.
The institute office's letter reached the station that same afternoon, asking for a written explanation. Old Tang brought it to her. He said: someone at the station asked me whether your data can be trusted. He said: I told them one sentence—I've trusted her numbers for twenty years; whoever doesn't trust them, go compute for twenty years yourself. He said: you still have to answer the letter. This time, write a few more words.
She wrote twelve hundred characters. Twelve points: item by item she conceded the facts, item by item she denied the motives. On the conceded side she wrote dates, wrote data, wrote whose tone of voice the phrase not yet had been said in. On the denied side each item got a single sentence: this item does not constitute the inference alleged in the charge. When she finished she counted. Twenty-four times longer than that forty-seven-character explanation.
The old assistance letters got dug up too. Someone posted last year's three instrument-pointing letters online under the headline: they were aligning their stories from the start. The engineer in the Miyun working group who had been suspicious early gave an interview and told the truth: at the time it didn't look like an instrument. Both sides cut the sentence in half. The front half became the insiders knew it was fake all along; the back half—doesn't look like an instrument means looks like what, I don't know—nobody reposted. Old Tang's old "checking the instruments" got translated anew as well. He read it and said only: let them translate. Checking instruments is what I said.
Lu Weiming spoke up in the group that day too. He said: you've carried off the second half of my sentence. Under that sentence there was another one, and you didn't copy it—the illness is everyone's, the table was computed by her alone. Whoever isn't convinced can start making up the hundred days of computation tomorrow. Four minutes later he added one more: I object to substituting an official line for an answer, and I object to substituting quotations for arithmetic.
Hu Yisu sat in her office spinning a pen, angry, and sent two pens flying off the desk. He said: Professor, dump all hundred days out there. Raw. One frame a minute. Let them look their fill.
She said: dump it.
She started packaging that night. Scripts, parameter files, scans of the hundred-line paper table, the ten o'clock spectrum snapshot from each day, all into one package. Halfway through she stopped. In the 3t directory, Zhou Yao's picture sat in the same folder as the edge graph. She moved the picture out and pressed it under the notebook, together with the twelve closed-eye people. Then she went on packaging. In the mailbox, the one titled "Shoulder" still read last modified 2459483.793. She glanced at it and didn't open it.
Just before sending, she dug out that station-office format form, more than four months overdue, its two rows still blank—raw voltage records, clock files. She filled them in, cell by cell. Medium: tape, eighth generation, twelve terabytes per spool, four spools in all. Estimated completion date, she wrote: this week.
When it was done she thought: this form really is nothing but an archive now. She had filled it in anyway.
The package went to the nineteen signatories, station office copied. Eighty-four megabytes compressed, sixteen-digit checksum. She made the list of the four tape spools three times, copied each spool number twice—one copy went with the package, one lay pressed in her own drawer. Sent at one in the morning. Hu Yisu watched the progress bar run out and said: clean.
She said: don't use that word for a while.
The second morning after the package went out, she found Hu Yisu had slipped in an extra layer: that alignment module he had rewritten himself, full source code, with comments, and the first line of the comments was still that old one—I'm the one who dirtied it. He told her: if there's going to be an audit, we're all audited together, starting from me. She did not take it out.
Lu Weiming sent her a letter of her own, three lines: don't answer anyone alone. Copy me on every reply. When you copy me, don't be polite.
On the third day Mateo posted a number in the group.
He had rerun the hundredth day. Not with her script—with his own eight-survey integrated time base, and error bars of his own. His hundredth day came out: 0.369. One line of English attached, the words as spare as ever: I used my own clock.
The group went quiet for half a day. Kramer surfaced first: I asked for that version of the data eight months ago precisely so I wouldn't have to read someone else's today. Nobody picked it up. He added half a sentence: still not too late to ask now. Still nobody. Observer Guan's reply was: the two parties use methods of the same family and share a prior; the conclusions share a source and do not constitute independent verification. That was common parentage. The fifth brick of her exclusion chain had been picked up whole and laid under the charges against her.
Mateo sent the longest thing he had written in half a year. He said: I did ten years in an ore-sorting plant. Two scales weigh out the same number, and you say the two scales were cut from one block of stock. Fine. Then bring a third scale, one with no kinship to these two. He said he had looked. There wasn't one. Every scale in service—clocks, ephemerides, software—had a pedigree that started after 1972.
Someone answered: what about before '72.
Nobody replied. Zhou Yan looked at that line and didn't type. She knew what was before '72. One spool in her drawer. Two in Beijing.
The review meeting was held on day one hundred six, by video, fourteen access points around the world.
For the first two agenda hours she listened to procedural statements. Amina chaired from the script, and when she read the words "scientific integrity working group" she did not miss a single character. The Sleepkeepers wanted 0.37 deleted from the report; the Wake faction wanted the hundred numbers appended as they stood. The two sides' motion titles differed by two characters.
The integrity working group's defense was agenda item five, and her name was not on the list. The secretariat's explanation was procedural: the inquiry targets procedure, not persons; the party concerned need not attend. She read that sentence three times. Not attending sounded worse than attending—had she attended, she could at least have read those twelve points back, one by one.
He Zhaoting joined during item four.
Nobody had been notified. The chair was mid-sentence when a new square appeared on screen—the Beijing access point, the camera angled upward, like a laptop propped on a stack of books. He sat in front of a wall whose edge was the edge of the tape shelves. He had aged more than a hundred days.
He held a sheet of paper in his hand. His hand shook; the paper shook too. He didn't wait for the chair to call on him.
I accept the data. Line by line, I have checked every line. If you mean to accuse her, accuse me first. But write this one sentence down—this data is too clean.
Then he looked into the camera and waited two seconds, as if for a question. No one asked. His square went gray. Amina, in the chair's seat, turned her script to the next page, her voice unchanged: the item is entered into the record. We proceed to the next.
The floor churned for half an hour. Two access points left the meeting on the spot; the reason field in both said technical failure. The Sleepkeepers said, you heard him, he said too clean, clean means fake. The Wake faction said, the first thing he said was "I accept"; only after accepting did he say clean—clean of a different matter. The two factions each carried off one half of the same thirty-seven-character sentence, and both headlines were online two hours later: one read "Father of the Silence Denounces Contaminated Data," the other "Founder: The Data Are Real, and One More Sentence."
Not one news outlet asked: why is cleanliness a defect.
The vote dragged on until adjournment. The concluding paragraph went to the floor: the motion to delete 0.37, eight votes; the motion to append the full table, eight votes; abstentions, eleven. Amina announced: wording of this paragraph is deferred to the next version. After the session both factions issued statements, and both said they had achieved their aim.
She thought of her own page—the Beijing page, where 12, 18, 24 still had blanks after them. He had stood up and said thirty-seven characters, and still had not said those three numbers.
Afterward the group scrolled past a hundred-odd messages. Ursula posted only three: one point is not a trend. Ninety-nine points are not a baseline. Keep computing.
Hu Yisu asked in her office: when he said too clean—did he mean you?
She said: he said "I accept" first.
Hu Yisu said: then what kind of defect is clean? Clean data has a defect?
She didn't answer. She pulled down the recording of that statement and saved it into 3t. For the filename she thought a moment, then typed: Thirty-Seven.
Saturday, 2459663, 20:00. The video call ran four and a half minutes.
The first thing Zhou Yao asked about wasn't school. It was: on the hundredth day, did you watch.
Zhou Yan said: watched.
Zhou Yao said: what did you see.
Zhou Yan said: a number.
Zhou Yao said "oh," and said that in her class kids still went up to the roof after school, and the lights still went off twice a week—the school had arranged that itself. She was peeling an orange while she said it, peeling it slowly, dividing the segments one by one to someone off-camera whom this side couldn't see. Halfway through the orange, her ex-husband's voice came in from beyond the frame: did you get your ears checked.
Zhou Yan said: checked.
He asked nothing more. Zhou Yao turned the camera back to herself and said: he's like that. Ignore him.
After the call, Zhou Yan went to check on Lao Wu. Water twenty degrees; the shell still unmolted; the antennae resting on the driftwood. She counted the shrimp pellets left in the tank and wrote it on paper. Of the date stickers on the tank wall, the top one said day one hundred; beneath it four more had been added over these past days.
Two texts on her phone. One was the hospital queue number—third reminder, third expiry. The other was a system receipt from the station office: the format form in last night's package had been answered: item received and filed. She replied: received.
She put on the earphones, the left one—the right one lately always had something padded under it. Thirty-seven characters, eleven seconds. Seconds eleven through fourteen were empty: those two seconds of his waiting for a question had survived in the recording too.
She listened to it through, then clicked it once more.
The eighth time.
