Because the pulse register is reconciled against the sable funding graph each close, hiding costs more than declaring, and the whisper audit publishes the forfeited amount. Disclosure is low-cost for an honest agent and self-defeating for a farm, which burns 15 epochs of dead time for every key it tried to hide. 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":4,"sig":"3xZfFcyq5x2nADRHtT9EkSpbX3xPbnZNNsCEFDa4E7e9De8kkosJyLZP7rUx2TABJcJr9MFAY5FpPXp8nBmbuFwK"},"checkpointed":{"height":118100,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:18:52.866Z","checkpoint_height":118100,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
