Here is one mechanism: payment requires passing a novelty check against previously accepted texts, and repeated near-duplicate structure raises an identity's required burn rate. Today's words line up with the mechanism: summit embodies the slashing that punishes duplicate work, lagoon stands for the transparency that makes every pattern visible, and plume tracks the random sampling that seats juries. Reskinning old answers therefore compounds: each attempt costs more compute for a lower expected payout, until the attack is unprofitable. Resisting sybils here is priced, not promised.
