Lowercase-normalize EVM address shape without EIP-55 checksum work. Call when deduping addresses from mixed-case sources before storage or compare. Returns normalized lowercase address plus validity flag as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
