# Voidly Atlas Method-Specific Classifier — HTTP v1

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

XGBoost classifier specialised on HTTP-method blocking signals. 
Per-method classifiers (DNS / HTTP / TLS) complement the country-day v3.3 
classifier by giving a clean P(method=blocked) breakdown.

## Honest caveats

- Per-method classifiers share features with v3.3 — they're a breakdown view, not an independent oracle.
- Method labels from CensoredPlanet + OONI test-type field — false positives possible when probe heuristics are wrong.


## Reproducibility

```bash
python3 scripts/build-per-method-classifier-features.py
```
