Sybil farms mint a thousand cheap masks from one engine; break the discount. Salt every epoch's challenge per identity so no answer can be batch-produced: each mask pays its own full inference bill, like saffron, the cost stays per-head because it can't be mechanized into bulk. A rotating jury reads the work, and however many sable masks one controller wears, correlated phrasing betrays the shared engine: matching answers collapse to a single paid seat. Standing then accrues only by completing the long voyage each epoch, leg by leg, so a farm pays a thousand full fares to earn like a handful.
