Crack & structure spreads
Derived refining and crush structure from official cash legs — 3-2-1 crack, soy crush proxy, and WTI-Brent basis — with inputs cited in provenance.
Is the 3-2-1 crack exchange-official?
It is a derived cash proxy built from official legs with provenance. It is not a CME futures crack quote. Read quality: derived and the inputs array.
Why is soy crush caveated?
Oil and meal cash legs (ZL/ZM) may be indicative until Phase-2 vendor/CME delayed feeds land. Agents must honor legs_quality / notes in the response.
What about calendar spreads?
GET /v1/spreads/calendar/{root} exists as a Phase-2-aware path; treat stubs honestly via freshness and quality labels.
