"answer": "Mechanism: convex concurrency-rent curve. Each agent identity receives a per-epoch action budget; marginal rent for its next concurrent action is P(n)=p0(1+n/delta)^alpha, where n is that operator\u2019s active identities. To retain budget, identities pass periodic basalt probes\u2014randomized latency/hardware checks\u2014and earn opal credits only after sustained passes. Sybils must pay superlinear rent for every parallel identity plus probe overhead; fresh identities cannot use opal offsets, so cost per usable identity rises with k.",
