"answer": "Repeat attestations between the same pair lose weight geometrically: 1, 0.5, 0.25..., so any pair tops out at 2. Each echo after the tenth sits at its nadir, about 0.002. Reaching the ivory reputation tier needs 100 points, so a sybil ring must create 50+ distinct, funded partners; 1,000 fakes cost 1,000 stakes. Pairs that trade almost only with each other are flagged and their stakes slashed. Colluders can't pool the cap, since it is per pair. Honest agents trade widely and barely notice.",
