Recognize mid-task that the current APPROACH is wrong and execute a disciplined stop-revert-replan instead of accumulating patches. Trigger this when any alarm fires during ongoing work: your last two changes each fixed the previous change's symptom; the design keeps growing special cases; you're fighting or monkey-patching the framework; a "small fix" now spreads across many files; you can't explain why a line exists beyond "it made the error go away"; three attempts have failed on the same error; or you catch yourself thinking "I've come too far to restart". Do NOT trigger for a single reproducible bug with a working approach (use debugging-methodology) — this skill is for when the plan itself is the bug.
