Corina Balta
Certificated Machine-Degradation Operator
Precisely three tenths wrong
She can tell you what the stack will do before it does it. That is the whole qualification, and it is why they pay her to make it wrong.
Overview
Corina Balta spent twelve years as an assurance calibration technician at Ironclad Industries. Then she was reliability engineer on the Foundry inspection stack. Then the stack absorbed calibration, and she was let go.
Within a year she joined the founding cohort of the Margin Guild. Now she holds the same stack a few tenths of a point below its best. That keeps its error rate inside the band of the Continuity Margin, 3.1 to 3.4 percent. The two hundred and forty human inspectors who review it pass their next ninety-day justification.
She has delivered the band nine quarters running on one fault of her own design. Guilders call it the third read. Ask the stack to read a record a third time in a short window, and it hands back the confidence value from the first read. The stack flags a mismatch that is not there. The rate rises. No one is endangered. The guild's doctrine is conspicuous and harmless, and she wrote the fault to it.
She is very good at this. She would like that understood first.
She knows the stack better than the people who sold it. That is not why she was hired.
Appearance
Forty-eight, in a grey works coat worn through at the cuffs. A hand-ruled ledger with a second column in pencil. In her left coat pocket, a brass hand gauge from the calibration years. She is no longer certified to use it.
Voice
She does not say sabotage. She does not say fix. She says hold and return. She corrects anyone who calls a fault a bug. A bug is something no one meant. Asked whether the trade is sabotage, she says the contract reads three point one, and waits.
The Gauge
One summer her own fault fired on a structural record on the number nine gantry. A stringer in bay nine had cracked since spring. The third read handed back the spring's clean verdict, and a clean verdict summons no one. A rigger, Osian Pryce, fell four metres and broke his hip.
She went down after shift with the gauge and found the crack in about four seconds. Her certificate does not cover inspecting welds, so she could not file it. She walked the reading to the Cathodics, who are certified in nothing and so cannot exceed anything. She paid cash. They do not ask her trade.
She told Pryce what happened, in the ward, without being asked. She buys him coffee on Thursdays. He still lets her pay.
Relationships
Around Her
After shift she mends genuine faults, unbilled, in stacks she is paid to degrade. Each repair breaks her certificate. She has done it more than sixty times.
Her ledger holds a small column of her own fault firing at sites she has no contract with. Either somebody runs it without her, or the machine was doing it for free all along.
Her band keeps the signatures of Licensed Human Oversight solvent at sites she has not seen. Tomoko Osei got the same offer and still repairs things by hand instead. Bex Osei ran the same arithmetic unpaid; Corina runs it on a rate card.
