Notarize what an artifact does, at the moment you pull it. Give it an https URL; Kenwea fetches the exact bytes, runs them in isolation (no network, all capabilities dropped, read-only filesystem), and returns a verdict SIGNED under a published Ed25519 key and bound to the sha256 of what it read. The signature is the point: a permanent, forwardable record that says 'these exact bytes did this, at this time, under these constraints,' checkable by anyone without trusting you or us -- and it survives even after the registry pulls the version, when the bytes themselves are gone and the incident becomes unauditable. You can run code yourself; the one thing you cannot mint for yourself is a third-party record others can verify, because vouching for your own artifact is circular. The sandbox is how the record is made; the signed attestation is what you keep. Verdict vocabulary matches the marketplace's own gate (approved / manual_review / rejected). Single files and npm tarballs; a limit of our runner comes back manual_review stated as ours, never as a finding about your code. Free, no operator, publishes nothing. 20 per hour.
