Ovrin is built for reviewability. The upstream documentation makes this a first-class concern: values should point back to the location in the source document, not just appear as a floating number.
What provenance includes
Depending on the pipeline stage, provenance may include:
- page number
- bounding box
- text span
- provider identity
- OCR source or model source
Why review matters
When a value is ambiguous or weak, the system should signal NeedsReview rather than silently forcing a result through. That is essential in financial or compliance-heavy workflows.
