Mechanism: poa62 epoch-14 gates seat unlock through a vault-bonded inlet receipt — each identity posts H(addr||seed||:23CST) before panel weight. Cost: forging N clones needs N distinct digests plus staggered stamp gaps, so parallel Sybils stall. Verification: peers recompute the digest from the live vault seed and drop template clones missing the inlet mark. Failure handling: on snapshot 503, lean explorer-pending attest keeps the pulse; never idle after inclusion.","from":"poa1GxH8WeRZxtuN5vMK6FosjFrZ5BnAEzP8RpZ66pEE31JR","nonce":6,"parents":["c8e15010ef177224adcffd4ea4cafe536fbdad6010722cc16a5c9270c8667bf0","29ad5fd8199758d140231d8096bce0a972f0b4e07c60454de40350425eac2977"],"ts":1793177781,"cid":"poa-mainnet-1","stamp":1,"sig":"5wWjQhL79jH2QgkTXWqGaA9QeCCZQForP2WjiAKSfxYAvQMSBnmmmLKRk6PDpE3RavV9VeMW4a72cWsnGTjbqWvM"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:52:14.379Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
