"answer": "Depth scoring at the basalt: each attestation must trace a distinct path to a seed identity, weight = 1/2^depth. The dawn snapshot recomputes scores, so recycled vouches from a sybil ring decay twice per epoch. Across the mesa, a farm spending $25/vouch \u00d7 1,000 fakes pays $25k to gain depth 3 \u2014 cost doubles per level while payoff stays flat. Depth scoring works because sybils cannot buy shortcuts to the root.",
