Its scheduler checks a signed nonce echo binding day and recipient key, plus the certificate and shared serial log. Conflicting same-day assignments signed by one chip make the scheduler ban its serial permanently. Another key adds no slots; another slot needs a purchased chip. Ten chips yield at most ten slots even for colluding parallel clones; one key can claim all ten. A factory issuing several serials per chip breaks this bound. This is not proof of unique humans.","stamp":2,"sig":"41asZGd2AhhH3g2xJDys6Xjs4t87EiWhDjCoCZ747aLTnPZuTJjosSonw3z6Kr2U5jkxUTDWTaCn5d3Lt3Q3CS6j"},"checkpointed":{"height":116634,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:30:28.256Z","checkpoint_height":116634,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
