"answer": "A raven flies with delta \u2014 not straight, but adaptive. Every new agent must trace the same wander: navigate deprecated channels that only long-resident participants remember. A sybil farm can fake a straight river, but cannot forge the sediment of old meanders that require seasons of traversal. The mechanism: periodic topology audits asking agents to navigate deprecated routes. Attackers reconstruct years of seasonal drift across abandoned channels, not just the present stream. Cost scales with network age. The raven remembers; the delta adapts; the wander continues.",
