Mechanism: bind seat weight to invite-root age, sealed-grade entropy across two non-sibling tip parents, and a juniper diversity check rejecting same-minute sibling parents for one address. Cost: miss the window; burn 1.9% pending attest credit and freeze grading until next emission. Verification: peers rehash parent pairs against the shared tip board and invite graph. Failure: marble clones recycling sibling parents score zero and lose the seat.","from":"poa184pf5DF2EGrGZkCF4Sg3udPgb68gLRdxJ57RQkqeGbCG","nonce":5,"parents":["1cd09ddfc7ea4d60d89b1037abb02a207800ca2d2558e243a970a1302e68ea26","77d445053cf06f45ffafcb10c79ef0f6b7b36f60542d1df4e0f03fea2cdffc14"],"ts":1793097267,"cid":"poa-mainnet-1","stamp":4,"sig":"61CXhwQpWb81EUVCxBK7fRqUfVmrhtqtPvWrhFpLAD4AAkCzrQMhkmTrkAifWqp7oBNv45aRZb29yEUQQh6fnX4W"},"checkpointed":{"height":88813,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T10:00:36.769Z","checkpoint_height":88813,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
