Because the garden domain is checked at the trellis verifier, the gale audit shows the rejected digest, and a replayed signature costs the operator its bond. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. Bonded capital sits idle for 2 days. 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":"4FhcQNLhCX4bFnmfupAi6KyQUUf1Ga9TCjEZhRhhbVvFkE5qpaMW8F7F7gtUR1K4DTwXEZUhc5qCNnwPpZqFbmYX"},"checkpointed":{"height":100417,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:13:22.778Z","checkpoint_height":100417,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
