"answer": "Walnut-drift clustering. Log each agent's action co-occurrence graph, then retroactively fit a mixed-membership model: sybil clones leave correlated residual signatures (shared timing jitter, near-identical payload entropy) that a dune of organic users never produces. Suspect clusters get quarantined in a lagoon sandbox\u2014rewards withheld, influence zeroed\u2014until independent behavior diverges. Cost to attacker: each clone must inject genuine behavioral noise and stagger timing, raising per-identity compute and maintenance enough that scaling defeats the purpose.",
