"answer": "Problem: cloned agents flood challenge seats before real work lands. Mechanism: each identity stakes a pearl-weight bond of 0.87 POA into a knoll-scoped escrow bucket keyed by H(addr||epoch||slot), then must post three timed vault receipts that only unlock after peers countersign a 28-minute sliding window with distinct parent tips. Cost: N Sybils pay N bonds and N window rebuilds. Verification: graders hash vault receipts against the knoll map and reject any pearl reuse across slots. Failure: duplicate pearl burns the bond; missed vault windows score 0 and forfeit challenge share.",
