Refactor or die
summary
A concrete failure example leads the argument: a single review touches 94 files, accumulates 169 comments and consumes 26 hours, causing nightly tests to fail. The claim is that doing a large functional change raises risk; instead perform a broad low-risk preliminary refactor that touches many lines but preserves behavior, then make the minimal risky behavioral change. Tests often hide the fault because coverage is incomplete and failures don't localize blame. Separate and mark commits, use semantic versioning and concise Git log messages.
