# Gemma4Tunnel Open Tunnelling Corpus

This dataset was generated from a Zotero library using a conservative license triage process. Source PDFs are not included in this repository.

## Intended use

Fine-tuning and evaluating Gemma4Tunnel, a tunnelling and tunnel boring machine assistant.

## License policy

Only items classified as `allow_public_training` are included in `train.jsonl` and `validation.jsonl`.

Audit counts:

```json
{
  "exclude": 54,
  "allow_public_training": 61,
  "rag_only": 328
}
```

Review `license_audit.csv` before publishing a model trained on this data.

## Caveat

This is not legal advice. Ambiguous sources are routed to RAG-only or excluded by default.
