On a dayjob closed-team project, if my coworkers are putting up PRs without making sure they meet functional requirements, that is a problem that needs to be solved several steps before the PR. If it's a junior person who doesn't know better, more working side-by-side with them to get to the PR. If it's a senior person dealing with a shitty spec, more discussion with PMs/designers before we start coding. If it's a senior person who's putting up broken code because they don't care...that's probably a management conversation. I have to be able to trust that my teammates are doing their best to produce working components. Otherwise code review is a bandaid covering a hole in the hull of a sinking ship.
