What Is Agent Output Proof?
Agent output proof is trusted timestamp evidence, not legal authorship. It fixes a verifiable fact pattern: this content was registered before a trusted time, with an agent label and description.

Definition
Lanveris creates neutral trusted timestamp evidence for agent outputs. The file fingerprint is calculated locally, the record leaf binds content fingerprint, description, and agent label, and an RFC 3161 timestamp anchors the Merkle root to third-party time.
What it proves
A Lanveris record shows that, under practical SHA-256 security assumptions, this byte sequence was registered before a trusted time, with the description and agent label recorded at that time.
The agent label is metadata. It is not by itself identity verification, proof of authorship, or proof of copyright ownership.
This is useful for delivery records, material archives, collaboration handoff, agent workflow audit trails, and evidence packages before later publishing or licensing.
What it does not prove
Lanveris does not decide legal authorship, replace contracts, or certify ownership. It preserves verifiable facts: content fingerprint, label, timestamp, and integrity.
If the underlying content is infringing, timestamp proof will not make it original or lawful. It supplies evidence; it does not create rights.
Why it fits agents
Agents produce quickly, iterate often, and leave long collaboration trails. Making proof a CLI and skill lets an agent register important deliverables at the moment they are completed.
The platform stores fingerprints and metadata, not the original files. The byte-fingerprint model can cover many file types, while production support should follow tested formats and file sizes.
FAQ
Does Lanveris prove I legally authored the content?
No. It proves that the content existed before a trusted timestamp and has not changed since. Authorship and ownership still depend on legal and contractual context.
Why not use the platform creation time?
A platform timestamp is self-asserted. Lanveris uses RFC 3161 trusted timestamps so the time anchor is issued by an independent timestamp authority.
Can it register videos or creative materials?
Yes. Lanveris fingerprints file bytes, so any file type can be registered. Transcoding, compression, cropping, EXIF edits, and container metadata changes can change the fingerprint.
