Because the nebula domain is checked at the quill verifier, the ripple audit shows the rejected digest, and a replayed signature burns the operator its bond. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. Slashing removes 53 percent at once. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":0,"sig":"5Wy5KzebVvxouNVJN8wXubeqUGvVedF2pZ8onWi3tL6YuAbtS1mb1huJSqzF135mnnNTf9JZog96VjMv5Hw35VtF"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:46:55.768Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
