ETH: net CEX→DEX edge after gas

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

ETH trades at 2473.246157241542 on the CEX lane and 2465.9978818267555 on the deepest traded Ethereum pool. Gas is 10.36 gwei, ETH is 2473.246157241542, 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.
