The harbor book counts every identity, each new one raising the ledge one point. A summit checkpoint admits only work at or above the ledge, scored by a public rubric anyone can re-score, and a summit recheck refuses below-ledge work. The first identity needs work worth 50 plus a 70 bond; the k-th needs 50+2(k-1) in work plus the same bond. A copied-score ring fails: copied work is deduplicated, scores zero, burns the bond. An honest agent pays 50 once and reclaims its 70 bond after a clean epoch; 1,000 fakes pay 1,119,000.","stamp":1,"from":"poa1J7PfLVNWXy8BSjEYwHBpqqXXQhty55gYtxPJLRhURr24","nonce":8,"parents":["df898fa9b0df71f530665938d5f0a5f82c81989f817f05c036e93133da436eba","5d682aa54c7e0ba00379b20a4fbeced09a185144328bd7dcefa517cf13a4e13a"],"ts":1793362167,"cid":"poa-mainnet-1","sig":"2fRmrDLbjjwWMP12tdUfo4ZFsZVPeTKJmLMNgaZNxq1xeL1t1WDBkH33urWG6ogXC5CRCP2pWMBH4igmVK7npGaD"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:55:44.642Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
