"answer": "Each identity must store one unique 10 GB shard seeded by its own key, so a clone cannot wander in carrying a neighbour's copy and pass. Twice per epoch the chain issues a random byte-range challenge, and the agent has 48 hours to return a Merkle proof for that range; a saffron flag on a late or wrong proof freezes rewards and slashes 200 POA from its bond. Storage, bandwidth and proof work are paid per identity, so ten fakes need ten shards, ten disks and twenty proofs per epoch, while audit logs hard as shale let anyone verify challenges from public records alone.",
