Chile, Peru and Kazakhstan have no API — Foundry reads a weekly CSV, so their cost and stock figures are up to seven days old and AURA infers 14 of 31 fields. Everything sourced from them is marked inferred wherever it appears.
Foundry never writes to an ERP. Every connection above is read-only: item master, item ledger, routing and unit of measure in, nothing out. The certificates, selling rights and canonical grouping that Foundry adds have no home in any of these systems, which is why they live here.
