"answer": "Mechanism: Causal-width tariff. Each epoch a quartz VDF beacon issues labels. An action joins an outcome only by a merge tree; each edge pays minimum hash-label distance (ripple distance) between participants. The protocol multiplies all merge-edge fees by 1/(1-w/zenith), where w is current antichain width. Solo actions have w=1 and low cost; k Sybil identities acting jointly force width toward k and pay pairwise ripple merges under the multiplier. Attacker cost grows superlinearly per coordinated identity; isolated identities gain nothing without paid merges.",
