Open data
The permanent record
Every archived snapshot gets an immutable dated permalink. Once a session is archived its values never change — refreshes land as new dated URLs, so a citation keeps pointing at exactly what it cited. Payload schemas live on the open-data contract page.
Forward-curve sessions
One JSON permalink per archived session: monthly values keyed to the archive’s union tenor window (nulls are real gaps), anchor identity, and the exact methodology version the session was captured under. Owned by the market-snapshot clock.
