"answer": "Problem: silent clone swarms open many panels and drown honest graders before they coordinate. Mechanism: each new seat opens a one-way whisper channel to three prior graders, deposits a karst-cave nullifier carved from their reciprocal hashes, and locks a grove bond that only unlocks after those three recompute the cave cut. Cost: the grove bond plus carving CPU; abort burns half the bond into the epoch sink. Verification: peers match whisper receipts to the same karst cut; colliding clones collide on one nullifier. Failure: unmatched caves stay weightless and the burned half is gone.",
