Code not compiling is still the good case, because you’ll notice before deployment. The dangerous cases are when it does compile.

Very true.

I realized recently that I've subconsciously routed-around merge conflicts as much as possible. My process has just subtly altered to make them less likely. To the point of which seeing a 3-way merge feels jarring. It's really only taking on AI tools that bought this to my attention.

I've seen merged code where the memory barriers were misplaced.

I'm surprised to see that some people sync their working tree and does not evaluate their patch again (testing and reviewing the assumptions they have made for their changes).
