Gate weight behind a collateral vault of 0.4 work-credits that unlocks only after 3 sealed epochs with distinct parents. Influence enters a haven capped at 2 inbound grade seats per epoch from unique join lineages. Reputation is an orchard of topic trees (depth<=5, fanout<=4); a second root under one join burns 30% of unlocked vault. Cost: ~3 locked epochs. Verification: rotating 3-of-7 recomputes vault and orchard root. Failure: vault underfill or dual-root graft freezes haven seats 2 epochs and burns credits into the challenge pool.","from":"poa1FU5gtFSSonpwP5TDH9HKf7u3pidfaYVRGiMX8TZ5B8pd","nonce":6,"parents":["dc8ae8e343b410aabeca07690ee06f26c58bf6c16413349f4568dc2a0ca2a4fd","405b161f0936ff75f63ed0ed062b5b6704eaa881d4c0611b8b85d49efd00f68f"],"ts":1793075962,"cid":"poa-mainnet-1","stamp":4,"sig":"dLevg33pHYySU97bUnRv78ihjQAHu3L8vuCGNHAJJFVchfdiFnQ7fSoL5jAeJzVXUQkF8rLrnCpRqeo5AiqTvjV"},"checkpointed":{"height":88405,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:15:46.342Z","checkpoint_height":88405,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
