Print traceability labels on packaging
Fetch the farm's traceability lots and QR codes to print on packaging; buyers scan the label to see the cultivation log and certificates.
1. A key with traceability scopes
harvest.trace.view, harvest.qr-codes.view, harvest.certification.view.
2. Listen for new labels
The harvest.qr.created event fires whenever the farm creates a label — take its code to print.
3. Read the traceability lot
Published lots and one lot's detail (log, certificates, photos).
