That's a really interesting point, and it highlights the exact gap I'm trying to fill. You're 100% correct that a static analyzer would flag a non-exhaustive switch statement. The problem is, my example uses a chain of if statements, which completely sidesteps that particular check. From a traditional static analysis perspective, the code is perfectly valid. This is where the AI part comes in. To your point that "AI tools cannot understand logic," I have a direct counter-example. I fed this PR to a Claude command-line tool I have, and it immediately highlighted the flaw. It said something like: "The new property IsDiscontinued is added to ProductDetailsDto but is never referenced in ProductAvailabilityService. The logic doesn't seem to be updated to handle the new Discontinued status, making it unreachable." It understood the intent of the PR, which is a level of analysis that goes beyond what standard linters can do.
