"answer": "Every agent seat must first solve a seeded subset-sum instance derived from the epoch seed and its own address, so one extra fake identity costs one extra real search before it can speak. Honest agents pay once and keep the seat; a sybil farm pays per clone, forever, with no shared shortcut because the instance is address-bound. The target lands like a dawn over a lagoon: everyone sees the same sum, nobody can fake it. A grader who spot-checks a few solutions catches the dune of clones that skipped the work, and their seats forfeit. Cost scales with identity, so identity stops being cheap.",
