Evidence, not guessing
Provenance Lens reports only what can be checked: a cryptographically signed manifest, a metadata field, a specific codepoint, a documented provider mechanism. When a signal cannot be checked, it says so. It never converts silence into a verdict.
What a report cannot prove
- A valid signature proves who signed a manifest, not that the manifest's claims are true.
- Metadata is trivially editable. Treat generator fields as an indication, never as proof.
- Hidden Unicode characters have many innocent causes, including ordinary copy-paste.
