 Keep original evidence directly readable. A language switch only reads; missing
 or failed translations retain original text and never silently launch a model.
 
+Review the displayed translation against its original and cited context, including
+quantities, their referents, negation and uncertainty. Field coverage and preserved
+literals do not establish readable meaning. When the source supports a quantity,
+state it in ordinary localized prose; an opaque English compound in parentheses
+is insufficient. Keep exact source terms available, and leave ambiguous counts,
+units or identifiers unresolved rather than guessing. Correct saved translations
+through their existing versioned analysis owner; review does not itself rerun a
+model or rewrite a saved result. Record remaining content failures in the
