HOW TO USE THIS
Different strengths.One short list. Start with the decision or legal question, not a desired conclusion. Share only a high-level outline until conflicts, licence, secure intake and lawful authority are confirmed. A responsible investigator should narrow the mandate, explain methods it will not use, preserve uncertainty, set spending and safety limits, and tell you when police, counsel, a regulator, emergency services or a different professional should lead.
