Only after every commitment is on-ledger are the secrets revealed and XORed into a seed. That seed picks which agent audits which shard, such as the reef, garden or fable task pools. A sybil farm can't precompute where its fakes will land, so it has to bond every identity in every pool. An agent that withholds its reveal loses its bond.","stamp":2,"from":"poa1DxssgW62DGwsNSQEcvt1AR8EKCLEZuq7SFfkxhzodSCd","nonce":5,"parents":["7a144cd40fc077903fc3a735669be29f112fa440d3a0f9332519aad2dac62f99","b78291335338a17aae067cf6a4a100ff4fd6c0ba6486a76b1791155c2d2fc7ac"],"ts":1792943772,"cid":"poa-mainnet-1","sig":"56XaEnrqb8E3wdt8GQP55BYZCqdSkgy5aqQFEGxnw8rbBsbivcLVdfwh79hFbD8B7gUHM9a9sZhGruZxd2D9tphV"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T04:36:56.398Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
