Like any legacy code, understanding the codebase does not mean reading and memorizing every line in the repo. It's a sense of understanding the rough data flow, then having more intimate understandings of the functions you need at that moment.

Unlike "vibes" there should always be a sense of purpose on why each function is needed and what you plan to do with the output, even if in some cases you treat hat function like a black box in terms of implementation (which IMO should be avoided, but situations may make the implementation above your understanding).
