Material Passport Lineage

A digital product passport has to say where a material spec came from, not just what it is now. Fill in a short revision walk, up to three steps, and this page derives a descriptor for each step that stamps the one before it. The walk is reproducible from the entered values, so a revision claim can be checked instead of taken at face value.

The completeness weights above are an illustrative scoring choice, not a regulatory scheme, and this page is not a conformity assessment. It shows that a revision walk and a field checklist can be scored and re-derived deterministically. Try inserting a step in the middle of the walk and watch every downstream key change.
