# MedGemma StructCore Demo (HF Spaces Zero)

This directory contains deployment assets for Hugging Face Spaces Zero.

## What is included

- `app.py`: Space entrypoint for the StructCore demo UI.
- `requirements.txt`: minimal dependencies for this demo.

## Recommended deployment flow

Use the packaging script from the repository root:

```bash
bash scripts/prepare_hf_zero_challenge_space.sh
```

It creates a ready-to-push bundle in:

```text
.dist/hf_zero_challenge_demo_space/
```

Then push that bundle to your HF Space repository.

## Model repository (two-stage)

Target model repo:

- `https://huggingface.co/DocUA/medgemma-1.5-4b-it-gguf-q5-k-m-two-stage`

Upload/update Stage1 and Stage2 artifacts from this project repo:

```bash
python3 scripts/hf_upload_two_stage_models.py \
  --repo-id DocUA/medgemma-1.5-4b-it-gguf-q5-k-m-two-stage \
  --stage1-file /absolute/path/to/stage1.gguf \
  --stage2-file /absolute/path/to/stage2.gguf \
  --stage1-path-in-repo stage1/medgemma-stage1-q5_k_m.gguf \
  --stage2-path-in-repo stage2/medgemma-stage2-q5_k_m.gguf
```

Requires `HF_TOKEN` with write access to the model repo.

## Space runtime configuration

Set these variables/secrets in the HF Space settings:

- `STRUCTCORE_BACKEND_MODE=pipeline` (or `mock` as safe default)
- `STRUCTCORE_STAGE1_URL=<your_openai_compat_stage1_url>`
- `STRUCTCORE_STAGE1_MODEL=<model_alias_from_stage1_/v1/models>`
- `STRUCTCORE_STAGE2_URL=<your_openai_compat_stage2_url>`
- `STRUCTCORE_STAGE2_MODEL=<model_alias_from_stage2_/v1/models>`

Important:

- Space itself does not serve GGUF automatically from the model repo.
- GGUF files in HF model repo are the source-of-truth artifacts.
- Actual inference in `pipeline` mode requires reachable OpenAI-compatible endpoints running those artifacts.
