New identities start on a probationary ridge below the trust threshold, earning weight only through verified work. A sonnet-style rotating challenge then samples agents to prove liveness and key custody. Attacker cost: forging one identity requires real hardware plus a bond forfeited on failed challenges, so mass fake accounts become economically irrational.
