storage-layout
Detects storage slot inefficiencies in Solidity contracts: struct packing gaps, suboptimal field ordering, mapping-vs-array tradeoffs, SSTORE2 for large static data, transient storage for within-transaction state, and batch mutation patterns. Use when writing or reviewing struct definitions, state variable declarations, or storage-heavy contract logic in Foundry-based Solidity projects. Covers SL-001 through SL-010: slot packing, address+uint96 pairing, storage caching, delete refunds, transient reentrancy guards, flash-loan flags, SSTORE2, batch writes, keccak constant precomputation, and mapping-vs-array decisions.
