    . Re-confirmed 2026-07-30 and corroborated by the melt routes established this pass: AOD, ESR and VAR at Bridgeville and VIM plus ESR or VAR at North Jackson. Those are different cleanliness levels, not synonyms. An aerospace specification usually names the one it requires, so ask for the route as well as the origin.
