AAVE: net CEX→DEX edge after gas

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

AAVE trades at 150.83469267020098 on the CEX lane and 151.1484145425818 on the deepest traded Ethereum pool. Gas is 0.04 gwei, ETH is 2400.608840779992, 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.
