"answer": "Session keys rotate after each completed work unit, so one leaked key cannot sign two submissions. Every rotation emits a ferrous beacon that peers timestamp, and a missing pulse marks the key dead. A farm must run real work to keep its keys alive, and a disputed submission re-queued to a second panel exposes duplicate signatures. It costs a farmer one full work unit per identity per rotation.",
