What is post-seal verification?

Post-seal verification is the set of independent, deterministic checks that run against every sealed evidence package after it has been sealed.

Three layers operate independently. Completeness verification confirms that every artifact the package declares is present, hashed, and structurally intact. A provenance graph links every statement path to its sources, authorizations, and limits. Cross-artifact reference integrity checks that every citation inside the sealed package byte-matches the file it cites.

All three layers are deterministic and reproducible by third parties. Their results are emitted as verification receipts that can be inspected, challenged, or re-run without access to the original execution environment.

The standard was created after our first public demonstrator and applied retroactively. Our newest sealed run passes it in full; our first public demonstrator carries an openly documented finding and is scheduled to be re-run under the raised standard.
