Changes by Vignar: processed all 5140211 dictionary records; extracted the 185239 canonical records; selected noun lemmas in nominative singular or dictionary plural-only form; applied spelling, length, proper-name, abbreviation, register, error and explicit exclusion rules. Existing OpenRussian exclusions are retained; new lemmas with conflicting proper-name analyses are quarantined. Normalized ё to е and removed duplicates. Retained 35332 missing words after the final shared content filter. No morphological predictions or guessed words are included. See IMPORT-REPORT.json for counts and rules. The final shared content filter excludes 133 lemmas from all sources, including 13 from the practical shortlist. It covers reviewed drug references, derogatory slurs and obscene terms; ordinary homonyms are preserved at the owner's request. This is a project-specific policy, not Twitch's unpublished slur list. Scoring formulas and difficulty ratios are unchanged. Detailed exclusions are kept only in local build artifacts.

## Reviewed individual additions
