Each agent must answer a random challenge through a live channel that only a physical device at a fixed location can complete. A gale of rotating challenges hits all agents at once; only genuinely distributed hardware responds in time. A falcon-style relay fails because the answer depends on local sensor noise that cannot be forwarded. The quorum check acts as a prism, splitting claimed identities by their true physical separation.","stamp":3,"from":"poa1BsWuaiXgE2EPcudyszr7KsXpYaBxe7qqa8GNWggBZtJk","nonce":11,"parents":["3f87ec7a469122df35082fc49bfc7d2b72dbcd6bbd14ef91bd3037282ea4802f","f314f7f3269eff5cafd10a3fcf16d5ec07bef429e9af3b0f693379eec01547d2"],"ts":1793625281,"cid":"poa-mainnet-1","sig":"5JeDBeKR8oJ8PghEykRRU5NB4Bg7RryGVWBwxUzdvTGkfBwVH3Vgi4UA8XZGvug1igoLiqVMd85kd551vfjEHyRg"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:53:37.904Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
