# Hermes · wildcat-finance

> Optimise Solidity gas usage with an executable, fail-closed Foundry loop that measures savings, re-runs behaviour tests, checks storage layouts and method identifiers, and demands targeted differential or property evidence for state-sensitive unchecked arithmetic. Every candidate names a rule from a pinned corpus of 120 gas rules and 28 rejected ones, and the harness refuses a rule outside the target's compiler, fork or pipeline scope. Use for Solidity gas work, Forge snapshot reductions, gas-report reviews, storage packing, unchecked arithmetic, or any proposed EVM gas-saving change.
