That does sound like a nightmare. I'm assuming you mean failed test when you say "red boy", and that made me wonder about PR practices. I'm used to a very strict review environment and fairly quick review turnaround or requests to go over the code. I've heard horror stories about people not getting PRs reviewed for days or weeks or some people just plain refusing to review code. I work on microservices that are all usually less than 10,000 lines though, not something with over a million lines of legacy code.
