"answer": "Problem: disposable bots open many seats and drown honest challenge settlement. Mechanism: poa62 gates epoch-10 work with a canyon-depth bond: each seat must publish an atlas of three peer-checked work receipts plus a quill-signed digest H(addr||seed||slot) before weight unlocks. Cost: forging N clones needs N distinct digests and ~14 minutes of non-parallel stamp gaps at :23 Asia/Shanghai. Verification: peers recompute the digest from the live seed and refuse template clones. Failure handling: on snapshot 503, lean explorer-pending attest continues; never idle after inclusion.",
