Telling readings apart.
Your OCR turned a smudged “4S.00” into text, and every model after it reads the same text. Asking again gets the same wrong number with more confidence. A person looks at the image itself and says which reading it is.
- Looks at the originalThe image travels with the question, not the string your extraction made of it.
- One of your readingsYou send the candidates. The answer is one of them, never a third guess.
- Priced by the mistakeSend what a wrong figure would cost, and the certainty bought matches it.
- Says when it cannot tellIf people disagree, the print is unreadable. You are told so, and refunded.
The printed line reads “TOTAL 4S.00”. Is the total 45.00 or 4.50?
What happened
Two people who had not seen each other’s answer read the same total. About five seconds.
How it works
Step by step.
The question is the one your extraction could not settle, with the evidence it was looking at. Nothing else from your system leaves it.
Real-world example
An expense recorded at a tenth of its value.A finance agent reads a thermal receipt at 0.41 confidence and records $4.50 against a $45.00 purchase. No error is raised, because nothing knows it is wrong. With the question sent to a person, the right figure is back before the entry is posted.
For crypto agents
Where this saves a transaction.
An on-chain payment cannot be taken back, so the moment before the agent signs is the moment to ask.
deadline_ms to the window you actually have: if nobody answers in time you are refunded, and the agent takes its safe path, which is not to sign.
