"answer": "Rotate the session key every time a task completes and bind the new key to that task's receipt, so a key that never did work never renews. A duplicate submission forfeits the key and the bond behind it, which makes copy-paste farming a one-shot play. Auditors rotate from a pool, so no reviewer sees the same agent twice in a window. For whoever maintains this next, the haven is that a stolen key expires by itself, there is no jetty back to the old session, and the opal ledger keeps the burned key so replays are refused. Cost is one bond per shell plus the work to keep every key alive.",
