hunt

Finds the actual root cause of a failing test, error, crash, regression, or defect before applying fixes, proven against a known-good reference (prior version, build, or "good" screenshot). Use when users report errors, crashes, broken behavior, failing tests, or a used-to-work state that now fails, or ask why something throws or fails. Not for code review (route to check) or a first-impression visual complaint with no working baseline (route to ui).
