# Private Data, Public Findings

> Two labs share a Mareforma graph but never share raw data. Provenance travels; proprietary data does not.

  `examples/04_private_data_public_findings/`
</Card>

Lab A discovers a finding and publishes its provenance trace. Lab B reads the
trace, replicates on its own private dataset, and publishes back. The graph
answers three questions automatically:

1. **Independent paths?** Different data sources, or both from LLM prior?
2. **Genuinely reproducible?** Stable across datasets, or a data artifact?
3. **Provenance distance?** How far is each conclusion from raw data?

Also demonstrates spurious REPLICATED, two INFERRED claims repeating the
same LLM prior, and how to detect it from `classification`.

## Run

```bash theme={"dark"}
pip install langchain-core
cd examples/04_private_data_public_findings
python 04_private_data_public_findings.py
```
