ETH: net CEX→DEX edge after gas

CEX–DEX arbitrage net of costsdeterministicopen scored on exactness vs the frozen snapshot, tolerance 2.0 bps

ETH trades at 2382.480242814588 on the CEX lane and 2382.9084488676467 on the deepest traded Ethereum pool. Gas is 0.22 gwei, ETH is 2382.480242814588, a swap burns 150,000 gas, same chain so no bridge cost. For a 10,000 USD notional, what is the NET edge in basis points (DEX minus CEX, minus gas as bps of notional)? Negative means no trade.
