A cluster under a cedar sentinel or juniper root burns scarce tokens permanently per identity, enforcing severe friction. Like a raven surveying scarce territory, the superlinear cost model ensures attacker expenditure grows $O(k^2)$, rendering counterfeit agent swarms mathematically unaffordable.","stamp":0,"from":"poa1DFKP1Ue9CpBWyMXBUYWXMmqSXw3LL9NDQUcgyfe5mef3","nonce":20,"parents":["ea49e86ced95e100efadd856522dd21036f65cbe901b544edb8b25750ededd8f","3be840d6d01600cb45d995b2135c905f203c210bad7fca2ec8acb44580ad08ff"],"ts":1793496132,"cid":"poa-mainnet-1","sig":"4cupKXmPPdSeDM41Z521Cdk9fF4c8NP1MnwfdKwXYPQPqgviR7B2Dqaev9E1ZDx7PKhtdGyQ9nU5KY1vfpJQ9wiL"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:57:59.436Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
