Mechanism: meadow-plot bond\u2014lock 40 POA for 48h per address, then each epoch submit nonce proving SHA256(pubkey||epoch||nonce) has 16 leading zero bits (cipher work ~65k hashes). Cost: locked stake + one-time work. Peers recheck lock inclusion and recompute the hash. Early unlock or nonce reuse burns the bond and voids epoch grades\u2014no fable of reputation without bonded compute.",
