"answer": "Require each identity to prove it stores a unique, randomly assigned shard of public data. A verifier issues unpredictable spot checks, and only an agent actually holding its shard can answer in time; copied shards fail because each shard is salted to its identity. Like a dune reshaped by every wind, the shard set rotates each epoch, so precomputation does not help. A lone sparrow-sized agent can afford one shard, but a sybil farmer must buy storage and bandwidth for every fake identity, while an umber flag marks identities that miss checks and freezes rewards until they re-prove storage.",
