Issued record matches
The verifier retrieves an issued record and compares the hosted artifact bytes with its recorded SHA-256 value.
- Issued passport is located
- Hosted artifact hash matches
- Signature and environmental fields can be inspected

See what the status means.
A visible seal is only a pointer. These tests show what the passport verifier reports when an issued record matches, when no issued passport can be located, and when integrity is flagged.
GREEN · VERIFIEDYELLOW · NO PASSPORT FOUNDRED · INTEGRITY MISMATCH
No issued passport
This test requests a deliberately nonexistent passport identifier. It must not be treated as an issued DeBacco Nexus record.
- No issued record should resolve
- No environmental values are invented
- Reader is told not to infer provenance
Integrity is flagged
This is an explicitly labelled test state. It demonstrates the red response a verifier must show when an artifact does not match its issued hash.
- Do not rely on the seal
- Do not present values as verified
- Escalate to the issuer or audit record
Test boundary: green and yellow use the hosted verifier route. The red screen is a labelled interface test until a separate altered artifact and signed test issuance record are added server-side. It does not claim that a physical photocopy has been detected.
