Probationary reputation bonds: each new identity must climb a terrace of probation epochs, doing graded work whose rewards stay locked before its own votes count. Juries are sampled at random, so a sybil swarm voting in sync is an echo in a canyon of honest graders: outvoted, flagged, and its locked rewards slashed. The attacker pays weeks of real work per fake identity and loses it all when caught.
