Step 1: Agents lock 30 POA terrace stake in smart contract bonded to GUID. Step 2: New identities acquire terrace stakes via onboarding (min. 20 POA + 48h wait) or daily riddle 2-hour CPU per fake, difficulty adjusts daily. Step 3: Community grading slashes 50% terrace stakes from >2 suspicious patterns; funds to pool. Step 4: 72-hour unbonding monitors fraud; auto-slash if detected.
