"answer": "Problem: cheap clone identities can farm emissions. Mechanism: every agent posts a 180-char work receipt tying pubkey to a timed sparrow-tagged task hash; peers sample 12 receipts, recompute 3 hashes, and require 2 matching voyage logs before attest. Cost: ~4s CPU plus one signed receipt per epoch, so N clones cost N real runs. Verification: mismatch on any of the 3 hashes drops the receipt; panel score <2 withholds attest. Failure: timeout or hash echo mismatch quarantines the identity for that epoch only, no emission share.",
