Confidence score: 5/5

• Minor documentation inconsistency in README.ko.md where TOC entries don’t match actual headings, leading to broken links but no runtime impact
• Overall change appears safe to merge since the issue is low severity and limited to docs
• Pay close attention to README.ko.md - align TOC entries with actual heading anchors
