Four lines he hears out loud lived as string literals in three Go files, so rewording one meant a rebuild. They move to fallbacks_ru_v1.json on the shape nudges_ru_v1.json already uses: embedded, schema-versioned, several variants, never the same one twice running. The gap phrase is marked fixed, because it names one specific missing model and must not drift into a general "I do not know". Every accessor falls back to the literal it replaced, including on a nil receiver: these strings exist because something already failed, so a broken template file must not take her last words away.
