What this means in practice
This page is about the moment an extract looks useful but is not ready to trust yet. A date may have been pulled from the wrong attachment. A vendor name may come from an older thread. A status may still be wrong because the latest reply changed the situation. That is where teams usually fall back to spreadsheets and side notes, because they do not want a bad extract feeding the next step.
Polytrace gives them a review step before that happens. A reviewer can open the message or file behind a field, fix the value, approve or reject the extract, and keep the original source record intact. The point is simple: correct the working extract without pretending the raw record said something it did not.
