WEO codes declared by IMF_WEO_INDICATORS that the Datamapper does not actually serve. The transport returns HTTP 200 with an empty values envelope (verified live 2026-05-10) — never a 404 — so callers cannot rely on HTTP status alone to detect this. Route these through SDMX with the WEO 9.0.0 dataflow path produced by weoSdmxPath.
