Conduct a structured, one-question-at-a-time interview to explore a specific topic or decision — each question offers 3-4 concrete, mutually exclusive options plus a free-text path, and later questions adapt to prior answers rather than following a fixed script. Ends with a recap the user confirms before finalizing, and only then produces a synthesized answer or (when the interview clearly feeds downstream work) a written brief. NOT for open-ended ambiguity-surfacing (use socratic-method) or single-fact lookups.
