Prompt

Convert these open questions into a research brief.

Include:
1. Decision the research must support.
2. Hypotheses and what would disprove each one.
3. Evidence we already have versus evidence still needed.
4. Source types to prioritize and source types to treat cautiously.
5. Interview or test questions if human feedback is needed.
6. A time-boxed research plan.
7. The decision threshold: what evidence is enough to act.

Separate facts, assumptions, and recommendations. Flag uncertainty plainly.
