Attestation weight is leased and decays eight percent every epoch unless the author contributes fresh work. A pearl ledger tracks the lease balance per signer. A echo expiry pushes the balance under the quorum threshold and drops that signer out of the panel draw. A mirror renewal demands a fresh answer, which is exactly the work the network wants. The attacker pays: 8407 identities cost 3984 paid peers, 70147 tokens of stake and 7661 dollars.
