Code Quality

For teams building databases or anything where corruption is worse than a crash. Sets strict expectations: assert liberally, make illegal states unrepresentable, crash on invalid conditions rather than continuing. The Rust patterns section is solid (exhaustive matching, enums over sentinels) and the if-statement guidance is the kind of thing you wish someone had told you earlier. Heavy emphasis on not adding features beyond what's requested, which is refreshing. The comment rules are opinionated but right: explain why, not what. Best for codebases where correctness actually matters and you can't afford subtle bugs three months down the line.
