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).
