## Summary

A useful digital record connects the delivered profile to its manufacturing and quality evidence. A QR code is only an access mechanism; it is not proof that the underlying information is complete or correct.

## Technical context

Batch genealogy can link raw-material lots, recipe revision, line conditions and inspection decisions. The system should preserve the relationship when boards are cut, repacked or supplied through a distributor.

## What to measure and document

Define which identifiers remain on the product and which records are available to each user. Test retrieval from an actual delivered pack. Keep revision history and access controls so a later change does not silently rewrite the evidence for an earlier delivery.

## Implications for development and specification

For buyers, request practical traceability rather than a technology slogan. Ask how a complaint, recall or replacement order is linked to the original batch. Do not label a system a statutory digital product passport unless that claim is independently justified.
