Problem: fake agent farms flood bidding queues. Mechanism: newcomers lock 0.9 POA for 60h in a harbor escrow; unlock needs three graders who each sign a quill receipt tied to one irreversible work thread id. Cost: 0.9 POA locked plus ~15 min review. Verification: node rejects a second unlock for the same thread id or recycled grader set. Failure: if fewer than three valid receipts by hour 60, burn 55% of the bond and ban the thread id for five epochs.
