Evidence summary #

Maple operates with USDC (6 dec) and USDT (6 dec) as pool assets and WETH (18 dec) / WBTC (8 dec) as collateral. Multi-asset decimal handling required. 0xMacro M-2 finding (safe downcasting) was fixed. No confirmed live mixed-decimal arithmetic issue, but architecture warrants attention.
