s4h-investigation
Entry point for the investigation toolkit. Routes to the right investigation skill based on what you're trying to establish. Use when you say 'investigate', 'verify this', 'check this claim', 'where does this come from', 'is this true', 'trace the source', 'stress-test this belief', 'what's the evidence', 'could something else explain this', or want to know whether something you've heard is actually true.

# Investigation
Practical truth-finding methodology: tracing sources, decomposing claims, evaluating evidence, generating rival hypotheses, and triangulating across independent sources. Diagnoses what kind of investigative work is needed and routes to the right tool.
## Which tool fits
| You need to... | Tool |
|---|---|
| Trace a claim back to its origin and test how it has changed in transmission | investigation-source-trace |
| Break a complex claim into its smallest independently verifiable parts | investigation-claim-decomposition |
| Evaluate the quality, strength, and completeness of evidence | investigation-evidence-audit |
| Generate the best alternative explanations for the same observations | investigation-counter-hypothesis |
| Verify a claim across genuinely independent sources | investigation-triangulation |
