+# Research pass: Romania 1928 and neighbors — all routes exhausted, nothing verified
+
+Research checked on 26 October 2026. No entry or article changes: every
+source route tried this pass came back empty, and per the sourcing standard
+nothing was written from weak sources. This note records the dead ends so
+future passes do not re-chase them.
+
+## Romania 1928 (pop 19M, top actionable backlog item)
+
+- Romanian legal-medicine paper "Legal highs in Romania" (Gorun et al.,
+  RJLM; fetched and read in full): covers ancient Dacian plants and 2010s
+  "legal highs" deaths only. No 1928 law history. Not usable.
+- English Wikipedia (read via API): single sentence — "In 1928, Romania
+  established laws for countering narcotics, including hashish and its
+  preparations." No law name, number, or reference trail.
+- Romanian Wikipedia "Canabis în România": empty extract (stub or redirect
+  target without usable text).
+- Google-indexed UN Digital Library for a Romania-specific 1928 League
+  document: no relevant record surfaced.
+- Earlier context (prior pass): UN Geneva archives hold League dossiers on
+  Romania, but navigation is French-language archival search with uncertain
+  digitisation — not yet attempted, lowest cost/benefit of the remaining
+  options.
+
+The 1928 instrument's identity (law name/number, Monitorul Oficial
+citation) remains the blocker. Until it is found, neither the entry
+(Wiki-only) nor an article can advance.
+
+## Also exhausted this pass
+
+- ANNO (Austrian newspaper archive) for 1928 narcotics coverage: connection
+  failed repeatedly; alternatively the ALEX gazette wall and RIS pre-1945
+  gap stand. Austria 1928 domestic rules still unidentified.
+- Finlex deep paths for the 1966 Finnish decree (treaty-series guesses,
+  search-API inspection): no usable endpoint found; decree number still the
+  blocker for a Finland 1966 article.
+
+## Standing open gaps (unchanged)
+
+Tunisia 1875 (Duvall book), Syria 1943, Guatemala Decree 1331, Uganda 1902
+ordinance, ~60 estimated first bans (ET/VE/CU/BO/CM biggest needs).
