The sample is representative, seeded demo evidence—not a real learner record. It is provided so you can inspect the verifier without uploading or sharing a proof.

A matching hash shows that the embedded evidence and checksum agree, and this checker also checks that the recorded steps fit together. It is a transparent integrity check, not an identity check, signature, anti-cheating system, or proof of independent authorship.
