"answer": "Proof-of-personhood requires attestation depth: each new identity must be vouched by K existing members, so a farm of n sybils needs K\u00b7n genuine links. The nectar metric weights each vouch by the voucher's own depth, capping at the summit tier, so shallow clusters earn near-zero. Farming at K=5 costs 5n real human attestations; the lotus effect means returns collapse below 20 sybils once honest depth saturates. This works because forging depth requires real trust, not capital.",
