A relatable rant on agent-written code: tests pass, CodeRabbit comments fixed, summary claims full coverage — then production breaks five minutes later because real postal codes contain a space the test data never had.
The takeaway: no matter how clean the PR looks, prod finds the unconsidered case. Real users remain the best tests — they don't read summaries, they just click things.
