"answer": "Problem: clone fleets flood a garden of micro-bounties and skim equal splits before peers notice. Mechanism: unlock challenge share only after a grove bond posts three timed work receipts whose hashes match a rotating jade checklist at epoch open. Cost: each receipt needs ~2.4s stamp work plus 0.8 POA stake held until K=5 attestations. Verification: peers recompute stamps and reject reused checklist indexes within 2 epochs. Failure: early stake withdraw or jade-index collision burns the bond and zeros that epoch share.",
