Root-cause analysis and QA review for a PR, branch, or stack trace. Detects bugfix vs feature, then for a bugfix finds the commit that introduced the bug (the suspect set, via git blame/log), the bug's life story (intent, releases it shipped in, hotspot recurrence, fix completeness), and explains why it broke; for a feature maps the blast radius. Also yields a QA risk score, the tests to run, co-change ("did you forget X?"), and suggested reviewers. Use when the user asks "why did this break", "what introduced this bug", "root cause", "rca", "what does this PR affect", "what's the risk of this change", "which tests should I run", "did I forget to change anything", or "find the culprit from this stack trace".
