This is exactly the reason to use state machines/data flows IMO.

Every implementation is unique enough that simply following how data flows through the different states and transitions, and where the sinks and funnels are, will tell you everything you need to know about what your system is actually doing at any point in time.

The challenge there is, things like that are a shitload of instrumentation and requires a lot of forethought to not just jam everything into a framework that puts boundaries on what you can design and implement. So for 99% of applications, it's not worth the hassle and you're better off with just basic text documentation.
