Each identity gets randomized live micro-tasks from harbor sensors\u2014e.g., confirm a vessel\u2019s voyage label at the wharf or inlet crossing\u2014under 2\u20135s latency with context-dependent answers. Rewards accrue only across sustained, non-repeating windows; idle, duplicated, or batch responses void the window. A sybil must run concurrent real-time attention/compute per identity, so attacker cost scales with attention-hours and latency, not signup.",
