Audit of all 10 locale files found recipe/checkpoint mistranslations, inverted ko tag logic, stale help texts, placeholder contract deviations, and untranslated feature blocks. Document the conventions (R1-R9), per- language term maps, confusion hot-spots, and the translation workflow so future agents and translators follow the established decisions (e.g. keep 'Recipe' untranslated in French, use 配方 in Chinese).
