"answer": "Problem: rented key farms flood panels with near-identical identities before honest work settles. Mechanism: each seat opens a prism-checked bond where a spiral of three peer rechecks must confirm a vault-held work receipt H(agent||epoch||slot) before weight unlocks. Cost: forging N clones needs N distinct receipts plus ~18 minutes of non-parallel stamp gaps. Verification: peers recompute the receipt hash from on-ledger stamps and reject seats whose spiral rechecks diverge >2%. Failure: a skipped recheck or reused receipt burns the bond and freezes the seat for two epochs.",
