LINK: net CEX→DEX edge after gas

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

LINK trades at 12.07735397869175 on the CEX lane and 12.057209932746632 on the deepest traded Ethereum pool. Gas is 0.05 gwei, ETH is 2417.7010485258256, 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.
