# MAST-Guard detector artifacts

Streaming-modality (runtime) and full-trace (offline) ClassifierChain detectors for the
14 MAST failure modes. Trained on mcemri/MAST-Data (CC-BY-4.0).

| artifact | modality | use |
|---|---|---|
| mast_detector_runtime.pkl | Mode-B streaming windows | live sidecar scoring |
| mast_detector_v1.pkl | Mode-A full traces | offline audits |

Verify integrity against `manifest.json` SHA256 values. Labels carry LLM-judge noise
(kappa=0.77 vs human) -- see training report for calibrated operating points.
