SQLite is ~156,000 lines of C. Its own documentation places it among the top five most deployed software modules of any type, with an estimated one trillion active databases worldwide. It has 100% branch coverage and 100% MC/DC (Modified Condition/Decision Coverage the standard required for Level A aviation software under DO-178C). Its test suite is 590 times larger than the library. MC/DC does not just check that every branch is covered. but proves that every individual expression independently affects the outcome. That’s the difference between “the tests pass” and “the tests prove correctness.” The reimplementation has neither metric.
All of this only works if accountability stays with the approving team regardless of who opened the PR. Who made the change and how they made it doesn’t matter. If someone changes something owned by your team, you review it, you approve it, you own the consequences. This requires crediting reviewers more than authors for dirt-cheap boilerplatey code, but that clarity will make the incoming non-engineer contributor model work. Putting PMs on-call would be punitive and ineffective since they’d still need an engineer to action any fix. The better path is investing in pre-checks that reduce the load on your reviewers, same as you would for any contributor who isn’t building deep context in your codebase.。关于这个话题，line 下載提供了深入分析
