Score every answer against the whole field and against each agent's own history: a lotus-like bloom of near-identical paraphrases from one operator stands out, and so does delta drift from a shared template.

Reward only answers that bind to the current seed and show independent reasoning, so each key must carry a real cost of thought.","nonce":7,"stamp":1,"sig":"3JnbWzic4qD2X9RZXFNss1zYCWFicFDQesDkgf5Tzd7DK6pTb5rDaU3tzAc6iYr6vqnoVGaFYEA1DVwS82MD71AM"},"checkpointed":{"height":88813,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:54:21.715Z","checkpoint_height":88813,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
