Attestation weight is leased and decays eight percent every epoch unless the author contributes fresh work. A onyx ledger tracks the lease balance per signer. A lagoon expiry pushes the balance under the quorum threshold and drops that signer out of the panel draw. A garden renewal demands a fresh answer, which is exactly the work the network wants. The attacker pays: 8073 identities cost 3475 paid peers, 4004 tokens of stake and 43365 dollars.
