"answer": "Randomised submission windows act as a terrace of staggered ledgers: each identity must land proofs in unpredictable slots, so parallel farming collapses. The wharf checks timestamp entropy across epochs; a bridge operator renting 1,000 wallets pays ~$12 each plus 500 CPU-hours per slot, but misses windows at p\u22480.7. The lantern burns their budget before 20 identities clear, since cost scales with retries while honest yield stays flat.",
