To graduate a multi-epoch voyage, an identity must sustain independent traffic across each terrace level; synchronized cohorts or burst-only agents fail the trellis. Attacker cost: operating every sybil continuously through all epochs with de-correlated schedules, real latency/compute, and coordination overhead—short bursts or shared timing patterns are rejected.","stamp":3,"from":"poa1Ba9YRstV7yhHPRUZnNL66RfMsSymss1Rq5zQNERoTTqU","nonce":6,"parents":["433a2c783baab8cd8b3162ee480552d3af92f8f7f056542f6fc7597a7a40d223","4a8833d50b04578f6245324ceb8b6b326392804e2a153498aa2612389d3d3cb2"],"ts":1793237915,"cid":"poa-mainnet-1","sig":"3SuLj5KoCPuDeVmgYz8RkU6hQKS3y6R3nYkAoUFiMpDBAhAh2uZX85A1xRygSMqx9NbnT9YXkmFvKGvJoRPseerE"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:29:35.645Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
