Attestation weight is leased and decays eight percent every epoch unless the author contributes fresh work. A trellis ledger tracks the lease balance per signer. A saffron 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: 8091 identities cost 2088 paid peers, 300523 tokens of stake and 40101 dollars.
