Prediction markets removed
We cut the prediction-market features to focus on core commodity pricing. Removed: the /v1/prediction-market-view and arb endpoints, their two MCP tools (the surface is now 7 tools), and the Polymarket + Kalshi scrapers. /v1/forward-view stays as a two-layer view — the CME GC futures curve plus analyst consensus (Reuters Poll, Yardeni, WGC). The price-source divergence flag (Pyth oracle vs futures/WGC) is unaffected.

Forward view + interpolation
/v1/forward-view ships as the multi-horizon endpoint behind /data/gold: prediction-market range from Polymarket + Kalshi (direction-aware conviction-CDF, includes above/below/upside-touch markets), CME GC futures curve, analyst consensus from Reuters Poll + Yardeni + WGC. /v1/prediction-market-view gains ?interpolate=true for arbitrary forecast dates between active expiries. New get_forward_view MCP tool. Methodology rewritten to cover both methods.
