# DataForge Playground API

This is the API backend for the DataForge playground. The browser UI is deployed
separately through Cloudflare Workers Static Assets; this Hugging Face Docker
Space serves stateless CSV profiling and dry-run repair endpoints.

## What It Does

- Profile: detects type mismatches, decimal shifts, and functional dependency
  violations.
- Repair dry run: proposes fixes through SafetyFilter -> SMTVerifier and
  returns an ephemeral transaction receipt without persisting user data.
- Samples: serves small deterministic CSV examples for the static frontend.

## What It Does Not Do

- It does not persist uploaded files.
- It does not use cookies or analytics for file contents.
- It does not call an LLM by default.
- It does not perform autonomous production repair.

## Run Locally

```bash
python -m pip install -e ".[dev]"
pip install -r playground/api/requirements.txt
uvicorn playground.api.app:app --reload --port 7860
```
