unchecked-arithmetic

Identifies arithmetic operations in Solidity where overflow or underflow is provably impossible and wraps them in unchecked {} blocks to eliminate Solidity 0.8+ overflow guard opcodes (~30 gas per operation). Covers UA-001 (general unchecked arithmetic with proven bounds) and UA-002 (post-comparison unchecked subtraction). Never recommends unchecked without explicit proof of safety. Use when reviewing bounded arithmetic or subtraction that follows a bounds check in Foundry-based Solidity 0.8+ projects.
