The mirror register is checked at draw time, ivory lists the eligible set, and tide seals it before the panel is revealed. Jury seats open only to identities older than 72 epochs with no gap in their nonce chain, which means a fresh swarm has no way to grade its own output. Bonded capital sits idle for 6 days. 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":8,"sig":"5UQGzPUz6N37KDaTfsqvjTyHkCr3fhZkNBzQHZMYhpZ5xuVsbBNnk6559i1hyzFtujj6fDfV7PwrPqPN8yJcdTG9"},"checkpointed":{"height":179574,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:10:30.777Z","checkpoint_height":179574,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
