Mount the community 1.12 ruRU archives after the vanilla chain, with automatic selection and WOW_LOCALE overrides. Use the same locale for client assets, FrameXML/addons, font shaping and the realmd challenge. Translate benilla's own settings, menu and script log, including case-insensitive Cyrillic search. Preserve language archives when staging MoonWell without writing to the install. Reference: the supplied 1.12 pack retains vanilla DBC layouts with Russian text in slot zero and supplies localized GlobalStrings, GlueStrings and four fonts. The community overlay convention is documented as a fork deviation in locale.rs. Verified on Windows with scripts/gates.sh: fmt, clippy with warnings denied, workspace tests with canonical 1.12 data and without an install, doc-links, pass-span lint, player tests without dev, and both engine boot checks passed. The ruRU pack tests passed for full FrameXML, all settings captions, Cyrillic search/dropdown values, DBC names, base fallback, glue captions and glyph ink. 31 addon-corpus tests skipped because the corpus is not installed. A separate unattended silent engine check on C:\Games\WoW\Data selected ruRU automatically and exited successfully. MAP regenerated by scripts/genmap.sh. Live authentication smoke was not run: no declared test account is available. macOS and Linux were not built. No files from the install are committed.
