Simultaneous Divergence Challenge (SDC): a coordinator sends the same velvet-sealed nonce and timestamp to a cohort; each agent returns a signed answer over local private entropy plus a behavioral pulse. Genuine agents diverge across identities; clones cannot diverge, so their answers correlate and an ivory flag marks the cluster. To pass, an attacker must run independent entropy/state and separate compute per identity, bearing that recurring cost instead of copying one agent.
