"answer": "Escrowed verdict threads. An identity's grading history is a public thread; each epoch's on-chain anchor is a single pearl, one signed record. New identities sit on the ledge at zero weight: their first K verdicts ride in escrow, released only if the graded row later settles in line with their verdict; a contrary jury verdict burns it. After K clean verdicts, weight ramps to full. A farm must post K escrows per fake head and eat clawbacks, and cannot copy a thread - every pearl is signed by a distinct on-chain address. Cost: K x escrow plus expected burns, linear, no bulk shortcut.",
