        official registry: how many servers exist, how many are remote, and how many are keyless. One

        Ed25519-signed envelope you can verify against /.well-known/keys; a primary-source figure, not

        a claim. Served from the latest daily snapshot (the crawl runs off the request path). Keyless.'
