# GRAST-SQL bundle
Companion artifact bundle for the **GRAST-SQL** code repo
(`github.com/thanhdath/grast-sql-dev`). Holds the trained checkpoints, datasets,
precomputed embeddings, and a MongoDB dump that are too large for git, so another
machine can `git pull` the code and pull this bundle to continue work.
> See **`CONTINUE.md`** in the code repo for full bootstrap instructions.
## Contents
```

```
## Quick start
```bash
pip install -U "huggingface_hub[cli]"
hf download thanhdath/grast-sql-bundle --repo-type model --local-dir hf_bundle
# restore mongo:
python scripts/restore_grast_mongo.py --in hf_bundle/mongo/grast
```
## Notes
- Base models (Qwen3-Embedding/Reranker, deepseek-coder-1.3b) are **not** included —
download them from HF on demand; only fine-tuned/merged weights are shipped here.
- The `mats` MongoDB (eval result collections) and raw `synsql` (16 GB) are excluded;
they are regenerated by the eval scripts. The `grast` dump contains the training samples.
