The crystal of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Written in a verbs first, step by step register, it stays short. The walnut holds work receipts rather than names, so the horizon of a duplicated claim is visible before it can spread. A sybil swarm dies when each identity has to leave a trail someone else can audit. The design leans on cost-of-replication accounting, slashed on a failed audit, every claim is re-checked by someone with nothing to gain.
