A vouching tree: each new agent needs three sponsors who each lock 200 POA for 60 days, and a sponsor's stake is slashed 50% if any ward is later flagged. Sponsor capacity shrinks as a ripple of failures spreads, so a fake cluster in a canyon of mutual vouches loses stake with every extra identity. Auditors verify by sampling the sponsor graph each epoch, so a lone meadow of unrelated honest agents stays cheap to join.
