description PDFのワークシートを、難易度を保ったまま少し新しい類題に差し替え、LaTeXで数式を正しく組版した新しいPDFとして作り直す skill。平方根、分数、指数、不等式など、手描きではなく数式組版の品質が重要な教材に使う。

An architecture design for tracking COVID-19 proximity that incorporates privacy
Backend publishes 2 APIs
1. Fetch Near-to-Infected list
Near-to-Infected list entry consists of:
- userIDs that have been near to an infected person
- Time when the userID was near an infected person
This can be a static text file that gets updated when E-2 happens.
2. Append Near-to-Infected list
This is going to be called when a person was diagnosed as positive.
See E.
