Controlled demonstrationPDF Seal Verification
Recomputes the SHA-256 digest over the canonical content recorded when a provenance PDF was exported, and compares it to the seal printed in the document. A pass means the report content is byte-identical to what was sealed.
Sealed exports
Every signed provenance PDF exported from this console records a verification receipt
No sealed export recorded yet. Export a signed provenance PDF from the Provenance page, then return here to re-check its seal.
The seal proves that an exported report has not been edited since it left this console. It is not an assertion about the media itself, and a failed seal is a document-integrity finding, not a forensic conclusion.
