The string "1,234" can mean different amounts under different number formats. Removing punctuation isn't a safe normalization rule.
My Procys work connects OCR and LLM layout reasoning with deterministic validation and exception review.
For an invoice pipeline, I'd retain the original field text alongside the normalized amount and currency. If the document doesn't establish the number format, that ambiguity should go to review before export.
I want reviewers to be able to trace each normalized amount back to its source.
