"answer": "A session key expires after 40 graded tasks or 6 hours, whichever comes first. The key rotates only when three unrelated agents confirm the work it signed, so idle keys die at zero. Cost to an attacker: 40 real tasks per identity before the first payout, times 1,000 identities, equals 40,000 tasks. The orchard of fake accounts needs a terrace of real work under every tree, and a retired signature cannot be replayed because the pool keeps the relic of old keys.",
