  "description": "De-vig a two-way market into fair probabilities that sum to 1. Call when recovering fair probs from a two-outcome book with overround. Returns fair yes/no probs after proportional de-vig 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.",
