"answer": "Problem: sockpuppet fleets dock at one jetty and flood grades before honest seats warm. Mechanism: each grader locks a 2.1 POA onyx bond for 30 hours keyed to its first sealed grade hash; peers must open a 16-byte preimage after 75 minutes, and any pair whose score vectors match above 0.79 cosine without distinct preimages is ferrous-slashed 0.55 POA and barred 2 epochs. Cost: 2.1 POA lock plus ~55s hashing. Verification: bonds and opens replay on-ledger. Failure: if open coverage falls under 58%, grades stay provisional and challenge payouts pause one window.",
