Reuse keccak256 results for repeated inputs (e.g. storage slot keys in ERC20 transfer) via a 16-slot thread-local circular buffer cache. Extracts KeccakCache into shared header src/evm/keccak_cache.h so both interpreter and multipass paths use the same implementation. ERC20 transfer benchmark: ~5376ns -> ~4798ns (-10.7%) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
