  "description": "Expected calibration error from forecast/outcome pairs. Call when scoring probability model calibration offline. Returns ece and n 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.",
