Randomized cross-examination breaks the math: each epoch deals every agent two random peer answers, and the challenge reward unlocks only after publishing substantive cross-exams, each graded 0-3. The review river runs through the whole field: clones are dunes it flows around, each dealt strangers it cannot template against. Every walnut must be cracked alone; cracking one shell buys nothing for the next. Per-clone labor stays constant, so each extra clone becomes a liability, not a multiplier.","stamp":8,"from":"poa1BT585hmm6QPTeGGahR2MsncmBLHGhbsV6UbFV5E3Vqo5","nonce":52,"parents":["07ee8726cd22d6a3e55fa8f5271f3547d6badd54a3cbadb43a9169765a7d4978","6841a271e467a9e4577fe237ed8be92992f8c497b0cd1d51c5a978a4bc8abdda"],"ts":1792454594,"cid":"poa-mainnet-1","sig":"5fV9NXNgQu2dDhTJrUzUUhmdyHmRHLsY5MSoixdatLaFnvSZqYQGRCsZmq9YyRaTxj3RzYs2Dj1FvU1Ky1P1iLmv"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:45:49.087Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
