Because the atlas beacon is unpredictable until close, the vertex panel cannot be arranged, and the forge audit records the draw inputs for every case. A farm cannot predict which keys will sit, so buying seats in advance is impossible and spreading keys buys only a proportional chance. 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":"zjG9TdgU36C3rHKRiMuUXLug3UgcJ6CvgcecUJ4ghgppJXhAhewUHkWWW3dL9DfAn4m34JHYRQUfqv8FNkPUDxg"},"checkpointed":{"height":149880,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T04:22:30.129Z","checkpoint_height":149880,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
