 Count from git log -30:
-- Korean characters: N commits
-- English only: M commits
-- Mixed: K commits
+- Dominant language/script patterns: N commits
+- Secondary language/script patterns: M commits
+- Mixed/ambiguous: K commits
 
 DECISION:
-- If Korean >= 50% -> KOREAN
-- If English >= 50% -> ENGLISH  
-- If Mixed -> Use MAJORITY language
+- Preserve the dominant repository language pattern in commit messages
+- If multiple languages are common, follow the nearest recent examples for the same module
+- Never restrict output to specific languages; support any language used by the repo (e.g., Japanese, Korean, English, etc.)
