This design document outlines the transformation of CiteScan from a
verification tool into a smart bibliography management system. The key
feature enables automatic detection of arXiv preprints that have been
officially published, providing users with easy access to both versions.
Key design decisions:
- Focus on arXiv → AI/CS conference conversion only
- Dual-link UI (arXiv + Official) for user choice
- $0 maintenance cost using existing free APIs
- Manual BibTeX copy from venue websites (pragmatic approach)
Also updated .gitignore to allow docs/**/*.md files.
