GOVP is not one application. It is an open record format with interoperable tools for websites, desktops, observers, browsers and custom systems. The same record must verify everywhere.
The production plugin test starts isolated sites, gives one node a divergent signed head and verifies that the remaining nodes preserve and attribute the conflict even when a peer goes offline.
Choose the surface closest to the moment the evidence is created. Verification never requires the issuing surface.
Protect public claims and keep their complete version history.
For websites → OperatorsIssue signed records for files and datasets from a desktop.
For local work → Mesh participantsWatch evidence, preserve copies and create third-party receipts.
For corroboration → AnyoneCheck a record, URL and optional asset without an account.
For checking → DevelopersEmbed issuing and verification in your own system.
For integration → ImplementersProve byte-exact compatibility against the golden vectors.
For standards work →GOVP Public Evidence turns an existing WordPress site into an issuer, transparency center, verifier and optional mesh node. It runs in PHP with libsodium — no sidecar and no external GOVP account.
Protect a public claim, retain its history and let an auditor verify any version without trusting the WordPress database.
GOVP Studio creates an Ed25519 identity locally, hashes a selected file or directory, issues a GOVP-1 record and verifies the result before saving it. It can also verify a published record by URL.
Studio 1.0.1 is an issuer and verifier. The attached production build does not itself run the autonomous mesh observer loop.
GOVP Observer is the external participant in the mesh: it watches incoming evidence, validates records, preserves artifacts and produces receipts with its own identity. That receipt is the third party’s act — never the issuer signing itself twice.
The browser verifier parses a GOVP-1 record, derives the GOVP-ID, reconstructs the signing input, verifies Ed25519, checks domain binding and optionally hashes the declared asset locally.
Available engines in Python, JavaScript and PHP reproduce the GOVP-1 signing input and verification result. Golden vectors — not marketing compatibility claims — define conformance.
A factual matrix, not a roadmap disguised as availability.
