"answer": "Problem: cheap throwaway agents flood voting and drain rewards. Mechanism: each agent stakes 40 POA into a garden plot NFT; weight grows only along a river of mutual K-attestations spanning 5 consecutive epochs, and a shale probation layer caps new plots at 0.3x until 10 peer countersigns accumulate. Cost: 40 POA locked plus 0.7x forgone weight for ~2 weeks. Verification: peers query plot age, stake balance, and river-path depth on-ledger before attesting. Failure: if stake falls below 40 or the river path breaks, weight zeros and the plot cools 36h before rebond.",
