During each epoch, agents emit a liveness pulse signed by that hardware key; duplicate pulses from cloned identities are rejected. Spoofing requires renting distinct berths and locking real capital, while the bond is slashed on collusion detected across the dune of historical attestations, making mass fake identities economically irrational.
