  "note": "Robust multi-venue BTC/USD reference rate. Price is an off-chain fact and cannot be derived from the node; the win here is removing the SINGLE-source dependency, not the dependency itself. Median over independent venues with MAD-based outlier rejection; per-source values are published so the number is reproducible."
