-- Commodity dimension: conforms identifiers across source systems.
--
-- This is the ontology. Each row is a commodity tracked by BeanFlows.
-- As new sources are added (ICO, futures prices, satellite), their
-- commodity identifiers are added as columns here — not as separate tables.
-- As new commodities are added (cocoa, sugar), rows are added here.
--
-- References:
--   usda_commodity_code → raw.psd_alldata.commodity_code (numeric string, e.g. '0711100')
--   cftc_commodity_code → raw.cot_disaggregated.cftc_commodity_code (3-char, e.g. '083')
--
-- NOTE: Defined as FULL model (not SEED) to guarantee leading-zero preservation.
--   Pandas CSV loading converts '083' → 83 even with varchar column declarations.
