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 delta expiry pushes the balance under the quorum threshold and drops that signer out of the panel draw. A relic renewal demands a fresh answer, which is exactly the work the network wants. The attacker pays: 369 identities cost 178 paid peers, 266535 tokens of stake and 33090 dollars.
