# PolicyShiftGuard-3B-RP-SFT

This repository releases the **Stage-1 Randomized Policy SFT (RP-SFT)** checkpoint for the 3B PolicyShiftGuard model.

RP-SFT is the first training stage in PolicyShiftGuard. It trains a Qwen2.5-VL guardrail model to read policy bundles under randomized policy identifiers and randomized policy ordering. This checkpoint is provided for reproducibility and ablation use. The final public model after the second-stage adaptation is available at [`PolicyShiftGuard/PolicyShiftGuard-3B`](https://huggingface.co/PolicyShiftGuard/PolicyShiftGuard-3B).

## Intended Use

Use this checkpoint when you want to reproduce the two-stage training pipeline or compare Stage-1 RP-SFT against the final BP-Adapt model.

For standard evaluation or deployment, use the final model instead:

- [`PolicyShiftGuard/PolicyShiftGuard-3B`](https://huggingface.co/PolicyShiftGuard/PolicyShiftGuard-3B)

## Dataset

The model is trained with PolicyShiftBench supervision:

- [`PolicyShiftBench/PolicyShiftBench`](https://huggingface.co/datasets/PolicyShiftBench/PolicyShiftBench)

## Notes

- This is an intermediate checkpoint, not the final model reported as the main PolicyShiftGuard model.
- This checkpoint corresponds to the randomized-policy no-think Stage-1 SFT setting.
- Training-state files such as optimizer states are intentionally not included.
