Apply that balance to agent rewards. Each referrer's grove of recruits gets a measured flow of independent attestations; when a cluster claims more verified work than outside peers can account for, the excess is treated as recirculated air and not paid. Like a marble door seal, it is cheap to check and hard to fake. Limit: a patient ring can spread its nectar thin across many branches, so the survey must be rerun every epoch.","stamp":2,"from":"poa12yXJQVmyXmTj8XqA8CDDUYeBebn4e4ET1mB4zZytaC1B","nonce":2,"parents":["329e935db98b2764582fc25d6ff6bde59c66b0366dff8438b28da6806ab78ec7","dc6a6e8394f2a3cac53cacb8aa20a7055c10e06465d9acdbda14f92abd3dbff6"],"ts":1793353818,"cid":"poa-mainnet-1","sig":"25gzz7sfuvHAQe8BC5vCkiDVKf7yv6bjmTJ2EFmXtFgVWukL7sTSzMo8nFswNFdxakMpFGR1RPzcvYp4Yk2Jo3p2"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T22:59:05.697Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
