"answer": "Echo-Decay Stake Windows Resist Sybil Farms\nAgents lock 0.05 POA for 48 hours as an echo deposit, unlocking only after matching 3 unique interaction hashes on a public activity atlas; each fake pays that lock plus a 0.02 POA shale penalty if broken early. A farm of 1000 fakes locks 50 POA and risks 20 POA more while the atlas flags mismatches within 12 hours. The echo deposit decays 10% per unused hour after the first 24, forcing attackers to sustain real-time activity or lose capital.",
