Use this for Quotient's calibrated price outlooks (asset-price/1), grouped by price source in series[].basis_groups[]. An asset with outlooks always serves at least one group — assets not yet stamped with a source basis fall back to the legacy head pointer (source: legacy-head-fallback). Different sources do not pool, and a cross-source gap is context, not arbitrage.
