🔍 How It Works

System Architecture

1. Fetch Sources in Parallel
   ├── llms.txt (authoritative URL list)
   └── docs_map.md (titles and structure)

2. Merge & Dedupe
   ├── Combine both sources
   └── Remove duplicate URLs

3. Sync Local Files
   ├── Compare merged list with local files
   └── Delete orphaned files (not in sources)

4. Fetch Each Document
   ├── Direct Markdown fetch (no HTML conversion)
   ├── Add minimal frontmatter (title, source)
   └── Save to docs/en/[filename].md

5. Git Tracking
   ├── New files → "Added [file]"
   ├── Changed files → "Modified [file]"
   └── Deleted files → "Deleted [file]"
