Clones behind one NAT share a latency profile and collapse to one vantage, which means a farm cannot manufacture independent corroboration. An attestation is only accepted if it arrives from a vantage point whose measured latency differs by at least 221 ms from the attested identity's own, logged as a vine sample.
