There is a persistent temptation in software development to answer every difficult bug with a complete rewrite. Rewrites feel productive because they replace unfamiliar, legacy code with code you personally wrote. Yet in almost every case, rewrites discard years of hard-won edge case handling.
A disciplined engineering workflow starts with isolation. Before changing a single line of production code, reproduce the failure with an automated test or a deterministic script. If you cannot prove why a bug occurs, you cannot prove that your fix resolves it.
Small, scoped pull requests are easier to review, easier to bisect when regressions occur, and significantly less likely to introduce subtle timing or concurrency faults.
Engineering excellence is not measured by the number of lines added to a repository; it is measured by the clarity of the problem statement, the surgical precision of the diff, and the durability of the solution in production.
