Scope
Follow entities, activities, and responsible systems across capture, generation, editing, export, and sharing. Content Credentials are one structured provenance mechanism; plain metadata, custody records, and source-system evidence can also contribute.
Questions worth testing
- Which origin claim is actually being tested?
- What binds the claim to these bytes?
- Which transformations or trust decisions remain undocumented?
Evidence and study material
Collect manifests, signatures, certificates, ingredient relationships, original files, source identifiers, and independent custody or system records. Retain the validation report and the trust configuration that produced it.
Methods to begin with
Limits on interpretation
A signature can validate under a particular trust policy without establishing that every assertion is true. Missing provenance may reflect stripping, non-creation, or unavailable records; it does not establish falsity.
Open research questions
Research questions include provenance survivability, interpretation of incomplete chains, and reproducible trust decisions across validator versions. Document whether an inconsistency belongs to the object, the claim, or the validation environment.
Tools, projects, datasets, and publication
The project’s release manifest and SHA-256 files are an inspectable example of byte-integrity documentation, not signed authorship proof. Reference JSON is available; there is no empirical provenance benchmark. Journal submissions should preserve their validator settings.
How do you test provenance survivability?
Begin with an asset whose creation and credential state are documented. Apply a defined export or sharing transformation and preserve every intermediate version. Check both the visible content and the provenance representation under recorded validation conditions.
Describe which assertions or bindings survived and which became unavailable. Loss of a manifest during an ordinary transformation is a different result from evidence that the original assertion was false.
