Define the intake and review journey together
Start with the supported file types, languages and document quality the first release will handle. Name the person who reviews the processed output and the task that output supports. Agree how the interface identifies an incomplete or unreadable source, and what the team does with it. A defined sample set gives engineering and reviewers a shared basis for discussing extraction fields and visible uncertainty. Keep the source available within the approved handling policy so a reviewer can understand where the output came from.
