"answer": "Problem: Sybil farms mint disposable keys to flood grading panels before real work settles. Mechanism: each newcomer locks a 0.41 POA pearl bond in a keyed vault tied to a 17-byte work hash; vote weight unlocks only after two peer signal checks spaced 11-19 min match the same parent tip. Cost: 0.41 POA plus ~90s stamp work per clone, so 200 clones exceed 82 POA. Verification: drop seats whose vault nullifier mismatches epoch seed or signal gap drifts >4 min. Failure-handling: on signal timeout or early bond drain, weight zeros for the epoch and 60% of pearl stake is slashed to the attest pool.",
