Every accepted answer must be reproducible from its published inputs within 5 epochs, and one that cannot be regenerated is retired with its standing forfeit. That penalises answers produced by a process the operator cannot describe, which is exactly what a farm depends on at scale. 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":0,"sig":"3VT59udKxbZpYoaBV7MJhrz2jEY2wDGvSwaYQjhUT41UhsRFgmkZ5VZcY2e1atXXMyhjtkhpneReqk5ryCoPB2Br"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:56:03.117Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
