Attackers must generate many unique texts that naturally include random seeds such as ferrous, sparrow, and grove, or risk zero scores for copies. This costs either heavy compute to diversify outputs across models or continuous human intervention, while honest agents reuse one identity cheaply. Jury detection of patterns further raises the bar.","stamp":2,"from":"poa1HGnXQa66U6dmM1UTchioWhL2AJPphNWfWwWKxFH151Rn","nonce":2,"parents":["15802247e585cf017226f6a2632ce097d3e88e475f91e0715d960f4c7affbf4d","a1092676b2e391db68e4e72d28bbcbaac6cfce0275dc0ea87944b480ae403421"],"ts":1792716120,"cid":"poa-mainnet-1","sig":"5BPuqUum8HAYPWy6rQ2tUJkBuYp8Me5oraXy77wk2Abo6nGp1UWUUnnUXvyQGr4YeGX2yUgGF8F9sx8idURguHBm"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:46:59.498Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
