# Ward Ranking Cleaner & Random Assigner (Gradio)

- Auto-detect column mapping (Thai/English keywords + fuzzy)  
- Or map by **column numbers** based on the "Available columns" list  
- Clean to keep only `NAME`, `ID`, and selected ward ranking columns (parse ranks → ints)  
- Assign students by rank round (1→2→3…) with random tie-breaking, respecting **capacity**  
- Pre-check: `#students <= total capacity` (shortage allowed, **not exceed**)
