The Error Floor
Contracted Machine Underperformance
Paid To Make The Machine Worse
The stack is not broken. It is held, by contract, at three point one percent wrong.
The Core Tension
Buy the safeguard another quarter
A human inspection wing is a real safeguard. Buying the error rate keeps it through each ninety-day review, and the people it keeps are real.
What it costs
Induced faults stay in a live system, and the contract never says which way they may fail.
An honest number or none
A safeguard paid for with a bought number has no honest cost, so its failures cannot be sorted into bought and free.
What it costs
Without the margin, a stack that measures too well releases the human wing.
"Two hundred and forty inspectors at the Foundry have work this quarter," says the guild's training film. "Ask them whether the number is fake."
That is a real argument. A human wing is a real safeguard, and buying the rate keeps it for another quarter. The people it keeps know their own names are on the payroll.
The objection is short. A safeguard paid for with a bought number has no honest cost, and no one can say which of its failures were bought.
The flaw that matters is smaller. A margin contract specifies a rate. It never specifies a direction. Balta tested the third read on records that started dirty, so the stale value was always a false alarm. The other case, a clean first read and a cracked present, was not in her batch.
Overview
Corina Balta makes a machine worse for a living. She holds the inspection stack at the Foundry between 3.1 and 3.4 percent error, every rolling quarter. Below 3.1, the human inspection wing fails its justification review and is released. Above 3.4, the vendor opens a remediation review. She has kept the stack inside the band for nine quarters.
Her method is the third read. Ask the stack to read one record a third time inside a window, and it returns the confidence it stored on the first read. The stale value disagrees with the present. The stack flags a mismatch that is not there. The rate goes up.
The invoice line says maintained assurance variance. The industry calls it the Continuity Margin.
How It Came To This
Ironclad keeps a person on every safety-critical line. The doctrine is sincere. It is also a budget line, re-tested every ninety days against the error rate of the machine the people review. A review layer that catches nothing is a cost with no product.
Workers noticed first. A form fed in badly or a duplicate entry left a mark against the machine and none against a person. Then procurement did what procurement does. A fault under a certificate has an owner, a delivery window, and a price.
By 2181, the Margin Guild had an apprenticeship and a doctrine. Its operators induce faults under their own certificate reference. Auditors check the number, not the method. The recruitment card reads: CONSPICUOUS. HARMLESS. INVOICED. Doctrine allows false positives, latency, duplicate entries, and dropped formatting. Nothing that could hide a flag.
Nexus Dynamics sells the stacks. Its remediation volume at banded sites is zero, and it publishes that figure under installation quality. Its position is that the practice does not occur in its installed base.
How It Is Lived
A stringer weld on the number nine gantry passed clean in the spring. By summer, heat from the pour line had cracked it. The stack scanned it for the third time that month and returned the spring verdict. A clean verdict calls no one. The wing was in bays four through seven. Osian Pryce, twenty-six years on the gantries, fell four metres when the stringer let go and broke his hip.
Balta saw her class fire on a structural record in her own ledger. She went down after shift with a brass gauge in her coat and found the crack in four seconds. She could not file it. Her certificate covers fault induction, not weld inspection. She took the reading to the Cathodics, who hold no certificates. They wrote it up for a fifteenth of the price.
Lately the third read fires in stacks she did not touch, at firms with no margin contract. A fault belongs to a certificate, and these have none. Either someone copied her, or the machine did it all along for free.
Pryce is back on light duties. He still lets her buy the coffee.

Key People. Tomoko Osei was offered a certificate and said she had only learned to make things work. Bex Osei ran the numbers and found they were kept for being cheaper than the machine.
Key Places. The Foundry sells hand-finished welds and buys the error rate that keeps their inspectors. The Cathodics are right for less and have no number to sell.
Key Institutions. The Lampblack sandbag themselves, unpaid. The Calibration Resistance steals four minutes each morning for free. Licensed Human Oversight is the profession the band funds.
