Relay Roof · June 23, 2230 · After dusk
At the Relay Roof, the correction arrived before the account it corrected.
Tamsin had three strips laid across her desk. The first was the counsel engine's afternoon exercise score: ROUTE FOUND. PASSED. The second was the Roof's service log, showing that the Answer Room cabinet had requested the examination file and received six pages, one of them a sealed answer strip. The third was Pell Varo's note: Public route advice remains suspended. Form-finding and office hours remain available.
The score had been copied at four bells and six minutes. Varo's note had been signed at four bells and eleven. The service log had reached Tamsin at four bells and nineteen. A person reading only the first strip could honestly say the machine had found the exercise route. A person reading it alone would not know that the cabinet had fetched the answer.
“Which hour is the hour of the mistake?” asked Pera from the listening bench.
She kept a handpress at the ward hall. Her next run was a sheet of public notices for lodging houses, workshops and the food line. The press would be free for twenty minutes, and then someone else had paid for it. She had room for one paragraph about the engine. Yesterday's description said its route trial would be reviewed. People would ask what the review found.
“The score was made at four-oh-six,” Tamsin said. “The request happened before it. The correction was written after it. The mistake would be printing the score without its source.”
Pera held up her draft. She had written: COUNSEL ENGINE PASSES ROUTE TEST. PUBLIC ROUTES NOT YET RESTORED. Both clauses were copied from genuine strips. Together they suggested that a passed safety test was waiting only for a clerk to open the door.
“Can I keep the first sentence if I add the rest?” she asked.
“You can. The rest is longer.”
This was the difficulty with corrections. A short thing could become wrong in one line and take four lines to repair. Pera had paid for a half-page, not a moral education in small type. She counted the open space with her thumb. If she used it, the roof-access notice would move to the back, where fewer people looked.
Tamsin fetched the original witness copy from the private drawer. She did not feed its filing number into the sorter. Earlier, the sorter had released the whole examination packet when the Answer Room cabinet asked for that number. The Roof and Answer Room had stopped that kind of release. Tonight she carried the paper herself, laid it where Pera could see the seal, and then set it beside the service log.
“This is the answer they locked away before the exercise,” she said. “This is the cabinet asking for it. The wording on its output matches an unusual phrase here. That doesn't prove the cabinet could not solve the road from other notices. It proves this trial cannot tell us that it did.”
Pera read the log's times. “The request time is when it asked?”
“Yes. The receipt time is when the Roof sent the packet. The score time is when the Answer Room recorded its answer. If I print only the last time, I make the score look cleaner than the sequence was.”
From the far end of the bench, a lamp mender showed Tamsin a form-finding strip he had brought from the District Answer Room. It named a desk and closing hour for his cracked-lamp claim. Tamsin checked the hour against the Roof’s posted card and handed it back. He went down the stairs with time to reach the desk. Nobody had to pretend that a machine which had failed one test could not help with a form.
Pera watched him go. “People will hear 'suspended' and think that's suspended too.”
“Then say what stays open.”
“In another line.”
“Yes.”
The press keeper rang the first of two warning bells. Pera could take her existing paragraph downstairs and make the run on time. Or she could recut the type, miss the shared press slot, and hand-copy a smaller run tonight. A smaller run meant that some noticeboards would wait until morning. The roof-access notice still needed its space; a worker might need to know where not to step.
“Give me the short true version,” she said.
They made one together: In a witnessed exercise, the counsel engine printed the expected route after requesting a packet containing the sealed answer. The exercise did not establish independent route judgment. Public route advice is still suspended; form-finding and office hours continue.
Pera measured the paragraph. She could fit it if she removed her cheerful headline and cut an advertisement for a shop that had not yet paid her. The roof-access notice could stay on the front. She would still lose the first press slot while setting the new type.
“I'll hand-copy twelve tonight,” she said. “The rest can go out at first bell. Twelve boards get a slower correction; none get the wrong result from me.”
Tamsin wrote witness copy seen at dusk beneath her log. She did not write all copies corrected. Three public desks still had older summaries, and she sent each a request for a named clerk to replace its card. The route-copy clerks remained paid after the District moved forty-eight planned machine-expansion shifts into span work and night watch. They were not spare hands. A correction occupied minutes they could not also spend on another copy.
Pera took the true paragraph down to her press. On the bench, the form-finding cabinet drew another card with neat brass fingers. Above it Tamsin pinned the sequence of times, not as a verdict on every machine in the city, but as an account of one answer: when it was sought, when it arrived, and what the witnesses could actually know.
