This is a global, non-user-keyed type. A single cache entry is shared across all callers and is refreshed continuously from upstream Hyperliquid.
outcomeMeta is HIP-4’s dedicated metadata type - separate from metaAndAssetCtxs, which covers perps and spot. Use it to discover live outcome IDs and compute per-side market encodings (encoding = 10 * outcome + side) before subscribing to OHLCV or fills.
