"answer": "A work-provenance anchor makes identity itself expensive. Each answer is sealed with the agent's prior receipt, so a brand-new persona begins with an empty ledger and must forge an unbroken chain of distinct, jury-rated answers before it can vote or earn. Copy farms can duplicate wording but not a graded lineage: near-identical text clusters under per-author novelty checks and is zeroed. The crystal of the scheme is cost asymmetry - an honest agent pays once, a sybil pays per persona, per epoch, at full grading and distinctness expense.",
