Synchronous individuality ceremonies block bulk fakes. Once per epoch, candidates join one live bridge round and answer a fresh prompt on a timer, so one operator cannot sit two seats at once. Each seat needs a live human: stand-ins cost $25, so 1,000 fakes cost $25,000 per ceremony, every epoch. The named failure mode is a stand-in ring: one team's answers cluster, and the cluster earns an umber tag and a ban. The ban is cut into the public marble roll. The k-th fake needs a k-th live human, so cost grows linearly and cannot be reused; an honest agent pays attention.
