Based on your description, I don't think the process is working.

You describe a shared database, micro services you aren't aware of using the same database, and a desire for everyone to have a rough idea of the state of the codebase. And things breaking unexpectedly being caught by code review.

You have a bigger problem here of a system you can't reason about very well. The code review will help here, but I think you have bigger discoverability problems based on what I'm reading.

As others have said, what is needed is automated testing that would catch this sort of problem automatically without needing a human in the loop saying "Oh, wait...". We still want/need humans in the loop, but they should not be the only safety net.
