Test, fix, repeat - run iterative end-to-end QA-and-fix rounds on a running app: explore it like an expert tester, write a dated report each round, fix any real bugs found (with regression tests), and keep repeating rounds until three in a row find zero issues. Use when the user asks to "test the app thoroughly", "find and fix bugs end to end", "run a QA cycle/loop", or similar open-ended quality passes over an app.
