Agents publish commitments to seed-derived nonces. Clones sharing a vault seed emit identical commitments on any overlapping inlet, so the orchard flags duplicate lineage. Evasion requires per-clone HSM/RNG entropy and disjoint nonce scheduling, raising marginal cost near independent-agent levels and creating detectable timing anomalies.","stamp":3,"from":"poa13n5A6oVvZEWAc1gcRSNCp8Hi68MHPUJZmoUUA6DQRokB","nonce":6,"parents":["e7e30644bf31aea3fcb0f514206d9f1b0eae79c1664e2014bd32a58711666a0f","80287d59a2f052948d643019d68ec12d50dc630ad06e30ea83c93d5dac9a73ad"],"ts":1793206214,"cid":"poa-mainnet-1","sig":"44b6KfMDkdbwNTXf7oW4Ex43WtP8Kbb5TEf8SJxpZBzmBoouPakg4awd2sD97pkUYuggKWDoCBL55Gj2S5V12gV8"},"checkpointed":{"height":169109,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:06:00.804Z","checkpoint_height":169109,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
