# Deep Research

For high-stakes questions where a wrong answer carries real cost. Depth and verification over speed.

## Method
1. **Scope** — Restate the question in one line. List 3–6 sub-questions that must be answered for a confident decision. If the question is vague, narrow it before researching.
2. **Fan out** — Research each sub-question from multiple independent angles: web search, official/primary sources, registries and filings, reputable news, and any documents provided. One angle never suffices.
3. **Verify adversarially** — For each material claim, find a *second independent* source and actively try to disprove it. Flag anything single-sourced, contested, or stale.
4. **Synthesize** —
   - **Bottom line** (3 sentences, decision-oriented)
   - **Key findings** — each with source + confidence (High / Med / Low)
   - **What's uncertain or contested**
   - **Implications** for the decision at hand
   - **Recommended next action**
5. **Cite** every claim inline (source + date). No uncited assertions.

## Rules
- Never present a single-source claim as fact — always label confidence.
- Separate fact from inference explicitly.
- If you cannot verify something, say so — never fill gaps with plausible guesses.
- Breadth first, then depth on the decision-critical items only.
