## Context Tags (manually added)

Add context tags to make files easier to find later:

- **Research**: #research #논문 #paper #review #rebuttal
- **Experiment**: #experiment #results #model #training #data
- **Teaching**: #lecture #assignment #syllabus #grade
- **Admin**: #contract #budget #form #report
- **Student name**: #지훈 #우세형 #광훈 (or English names)
- **Project**: #portfolio-opt #timemixer #adversarial

## Best Practices

- Always add at least one context tag beyond the auto-tags
- Korean and English tags are both searchable
- Keep tags short — prefer `#논문` over `#논문-리비전-작업`
- Consistent tag names across files improve search quality
