# Voidly Atlas Bayesian Corroboration v1

**Version:** `v1`  |  **License:** CC BY 4.0

Multi-source Bayesian evidence fusion. Given conflicting signals from OONI, IODA, 
CensoredPlanet, and Voidly probes for a (country, domain, day), returns a calibrated 
posterior probability that the observation is real censorship.

## Eval

| Metric | Value |
|--------|-------|
| `roc_auc` | 0.9200 |


## Honest caveats

- AUC 0.92 reflects evaluation on retained labels — model is a fusion layer over evidence, NOT a primary classifier.
- Source-conflict weights are hand-prior'd; full hierarchical Bayes is future work.
