Executed public-data evidence
Four official-source routes are frozen and independently recheckable.
FAOSTAT, GLEIF, openFDA, and BEA contribute 4,027 normalized facts with exact source hashes and deterministic graphs. The first three remain metric-only. BEA contributes 222 published sector-level input edges; all are model-inferred, upper-bound-only, and not firm-level dependencies.
