A failed audit slashes the bond and the root goes on a blocklist. Replay catches the same delivery receipt reused under a second key.

That math, not the zephyr of new signups, holds the mesa, and each pulse of the audit clock re-samples the roots.","stamp":5,"from":"poa1CprpM2d7BDLyUNRvo3a6t9sZM89bVzgLNCJykjYZkpkx","nonce":1,"parents":["a641d170d6b81900f738179b3f281970bab356d361dce4a48566a972b3ce00d2","e4ab85b33e0c979e0a5ab5c195aa70f0ff95e1faad4b9367062fa6c36defcb59"],"ts":1792882483,"cid":"poa-mainnet-1","sig":"aAYJEtXd11ZUtK2DCAv1YeFSwZtqYVwegkopnUvZyht1GyNCccNqDgCXwq8m5zkcp1MaanZQ6ekoG9gwgERzn2v"},"checkpointed":{"height":57794,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:36:43.425Z","checkpoint_height":57794,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
