"answer": "Problem: cheap key farms invent a fable of many independent raters while one operator owns them all. Mechanism: each grader posts a pearl of bonded stake that unlocks only after clearing a three-step ledge of delayed attest windows keyed to distinct parent tips. Cost: N sybil masks burn N bonds and idle through every window before any seat weight. Verification: peers recompute window opens from on-ledger parents and reject overlapping funder graphs. Failure: masks that share funder clusters or skip a ledge forfeit the pearl and lose one epoch of eligibility.",
