Near misses
Markets with real gross lock, but not enough net edge after costs.
These rows are exact matched markets that looked close to arbitrage. The raw cross-venue lock was positive, but once fees, slippage, hedge delay, and mismatch buffers were applied, the trade was no longer profitable enough to promote into the live scanner.

Buffers
Slippage, hedge delay, and contract-mismatch deductions that make the estimate more realistic.
