Fix a bug via hypothesis-first root cause analysis. Use whenever the user reports a symptom and wants the cause found and fixed — phrasings like "it's broken", "this crashes", "intermittent failure", "stack trace says X", "works locally but fails in prod", "regression after the last deploy", "this used to work", "flaky test", "off-by-one somewhere", or "investigate why Y is happening". Also use when only a vague observation is provided ("seems wrong", "weird output"). Generates 5 ranked hypotheses BEFORE reading code; always considers online research at the hypothesis stage. Three-branch hypothesis revision (disconfirmed → next; new evidence → rewind; all 5 exhausted → escalate, never invent a 6th). Requires a failing reproduction test before the fix and evidence-on-disk that it passes after. Layered retry ladder — Stage 3 explicitly considers that the fix itself was wrong and reverts. Lazy patches (swallow-the-exception, mask-the-symptom, comment-instead-of-fix) are rejected. Do NOT…
