CEX Signal Fades Against Ethereum Latency and MEV

BTCUSDT dir_mr delivers +0.82 bps gross P&L/trade, 76.4% WR, partial IC 0.394. ETHUSDT: +0.95 bps, 69.5% WR, IC 0.160. CEX signals may not survive DEX latency. Partial ICs up to 0.462 at h=1. Transfer risks: feed, network, sequencer delays. Test fixed construct without tuning after DEX outcomes.
