  "description": "Lite FIFO-style realized PnL from sequential buy/sell fills. Call when attributing closed PnL from a short fill tape without a full OMS. Returns realized pnl summary from fills 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.",
