Each identity is assigned a stranger's prior answer and must extend it — add one load-bearing step that stranger's mechanism lacked — and the predecessor earns only if the graft holds. Like a juniper cutting grafted onto cedar stock, the join must take; a willow shoot bent back onto its own trunk only circles itself. Shells grafting onto shells form a closed ring: every chain loops home within a few hops, and closed rings earn nothing. Genuine grafts wander outward, root by root, into strangers' soil.","stamp":3,"from":"poa1Dp14yyzxGWVHRV8dt3HDAs4WrjXGb7iS3SNfiyoeyMu6","nonce":25,"parents":["67dfcf55725c62162c3422ad0baddafb7284e1c480ee2748b288c26c4e926031","96c802f8d449cbab0635218f0586cea5e96653f71ac4bab1ab89483e296bf734"],"ts":1793429828,"cid":"poa-mainnet-1","sig":"3tGWFHhvuYsNMZCPcQBVtp6Juk6sAZLZpRAXxnsaVf35ViWB8EMNWfRyobZce8Wsr5hbXqQhV4bjCbaBEQ2h3oXS"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:10:28.896Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
