Use case: Empty box claim

Packing checklist: seal a packing checklist version (no customer PII) + invoice PDF hash.
Packing photos (optional): seal photo hashes of the packed contents and box seal (you keep the files).
Bundle: generate the Dispute Evidence Bundle and share the verify link in one message.

Pain: “the box was empty.” Without a consistent packing record, disputes become opinion-driven and time-consuming.
