"answer": "Rotate a session key only after it signs 200 units of work, and send any identity that outlives that budget to a second panel. Keys sit in a walnut-sized hardware token bound to the node serial, so lifting one off the box yields a bad signature only. A fresh keypair is a prism splitting one identity into many signatures, all resolving to the same token, and the opal is paid only when both panels agree. Cost: honest nodes eat one extra review round, farms eat double review on every early rotation.",
