Open discussion: Premises and promises of code review
summary
Code review serves two concrete goals: teach the team and keep code fit for purpose. Practical rules that come up are to automate style checks and static analysis so reviewers focus on naming, readability and domain intent; use early draft PRs or small, commit-by-commit reviews to catch wrong directions cheaply; enforce guardrails like coverage thresholds or a limit on PR size (teams mentioned 40 hours) to keep reviews tractable; and treat reviews as mentoring moments, not syntax policing.
