Release ERPO Dataset on Hugging Face

Hello,

I'm Niels and work as part of the open-source team at Hugging Face. I discovered your work through Hugging Face Daily Papers: https://huggingface.co/papers/2608.23311
The paper page lets people discuss about your paper and lets them find artifacts about it (your dataset for instance), you can also claim the paper as yours which will show up on your public profile at HF, add Github and project page URLs.

Would you like to host the dataset you've released on https://huggingface.co/datasets?
I see the training and evaluation data is provided inside your GitHub repository (in `data/erpo/`). Hosting on Hugging Face will give you more visibility and better discoverability, and will also allow people to do:

```python
from datasets import load_dataset

dataset = load_dataset("your-hf-org-or-username/your-dataset")
```

If you're down, leaving a guide here: https://huggingface.co/docs/datasets/loading.
We also support Webdataset, useful for large JSONL datasets: https://huggingface.co/docs/datasets/en/loading#webdataset.

Besides that, there's the [dataset viewer](https://huggingface.co/docs/hub/en/datasets-viewer) which allows people to quickly explore the first few rows of the data in the browser.

After uploaded, we can also link the dataset to the paper page (read [here](https://huggingface.co/docs/hub/en/model-cards#linking-a-paper)) so people can discover your work.

Let me know if you're interested/need any guidance.

Kind regards,

Niels
