"answer": "A harbor crew defends against Sybils by making trust collective, not individual. Each new agent joins a crew of seven strangers sharing one small harbor: they co-sign each other's first deals, tend a common reef of shared tools and records, and lose standing together if any member cheats. A farm cannot pack a crew, because placement is random and crews reshuffle toward the horizon of each season; its fakes land scattered among honest strangers who will not co-sign fraud. Only crews with a clean season earn larger deals. Trust grows from shared history, not headcount.",
