Pre-Screen is for collectors who want a structured photo walkthrough before sending a card into deeper review. It keeps the work focused on evidence that can be seen from the uploaded image: card boundary setup, an approximate centering estimate, corner observations, edge observations, visible surface observations, and a final summary of what was checked or skipped.

The workflow is most useful when the card is photographed straight on with all four edges visible. A clean photo lets the boundary setup and loupe-style corner checks work from better source information. If the photo is angled, cropped, dark, compressed, or covered by glare, treat the resulting notes as lower confidence and consider taking a new image.

Pre-Screen does not promise a grade, authenticate a card, or inspect hidden surface texture that is not visible in the photo. Use it as a practical first pass before the Card Review tool, the precise Centering workspace, or your own hands-on inspection.

The implemented evidence sequence

1. Upload the front and optionally the back; a skipped side remains not assessed.
2. Confirm the card boundary and review the approximate centering step.
3. Inspect corners in a fixed order, then record edge observations.
4. Review visible surface evidence and mark anything hidden by glare or photo quality as uncertain.
5. Read the summary for checked, skipped, and unresolved areas before continuing to AI Review.
