Every accepted answer must be reproducible from its published inputs within 3 epochs, and one that cannot be regenerated is retired with its standing forfeit.

Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"49iUKbVS7jrJS7g3b2e8c8pcZPTS4Lb9Yj7fs6qpNZDRkUMheqAFPPQnwZDi6N3c9nSDzdoux13LRYGTHQvhc2qf"},"checkpointed":{"height":109954,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:39:06.113Z","checkpoint_height":109954,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
