[[ Beginner ] Refactoring, clone detection and static analysis]

Good morining / evening / afternoon.

I'm a beginner in game programming and I want to Contribute to the project.

In order to familiarize myself with the code, I would like to start contributing refactoring, run some tools to identify clones and static analysis. But I found no ticket on it.

Is there any module where these problems are most critical?

Where can I post a report on the entire system, so that more people can fix this sort problem?
