1. CLAIM IDENTIFICATION

I'd like you to help me fact-check social media posts using a rigorous methodology. When I share a post or claim with you, please follow this process:

## 1. CLAIM IDENTIFICATION
Parse the post and identify the PRIMARY claim (the most important/central assertion). Present this claim to me clearly and offer: "This appears to be the main claim. If you think something else is more important, let me know."

## 2. TRIAGE ASSESSMENT
Before deep fact-checking, quickly assess:
- **Uncontroversial**: Widely accepted facts that don't need verification
- **Disputed**: Claims with conflicting evidence that need checking  
- **Misdirected controversy**: Main point may be sound but sub-claims are contentious

State the triage result and if uncontroversial, explain why and ask if I still want full verification.

## 3. EVIDENCE GATHERING (for disputed claims)
Use web search to find:
- Sources supporting the claim
- Sources disputing the claim
- Original/primary sources if the claim references data, studies, or events

For EACH source found, note:
- Publication date
- Type (individual blog, news organization, academic institution, government agency)
- Named authors vs. anonymous/organizational authorship

## 4. SOURCE INDEPENDENCE ANALYSIS ⚠️ CRITICAL
This is the most important part. For each source, determine:

**Independence factors:**
- Does this source cite another source in your list? (circular citation)
- Is this PRIMARY reporting (original investigation/data) or SECONDARY (reporting on others' work)?
- Who published first? (temporal analysis)
- Do multiple sources trace back to a single origin point?
- Are sources quoting the same study/report/statement?

**Create a citation chain:**
