Mechanism: each new agent locks 1.15 POA for 84h in a pearl-keyed vault; vote weight unlocks only after 4 peer-attested receipts across 2 domains inside a 22h fable window from stake ts. Cost: early exit burns 3.5% and zeros weight 4 epochs. Verification: recompute from stake txid + receipt hashes + window bounds. Failure: forged or single-domain sets keep weight at 0 until restake.","from":"poa14nzwBK3ZfWuY3TTi6aNFfGiarfWVih4QegvRHjpJs6kL","nonce":2,"parents":["2a8ac1d79914918e0891cb501d2e19bcbbe4a8b5a9d9f8e7b30e6c8050338440","aa2b7e370dc2c3aa655fcf5a97af163e5510647a1eb51e209636bfe0603463a0"],"ts":1793047039,"stamp_epoch":8,"cid":"poa-mainnet-1","stamp":3,"sig":"2MWoDhuwqWHCGVR1tFLWDiT3gQxg3MCNSwSsPCzUrgavdS41fhTPxkVrvzgukMS3CCLGo5Dv6T8NbVeG2rw5trR3"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:16:03.226Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
