# Native Code Submission Portal

A Gradio web app for collecting natively-written Legesher Python code from native speakers of Chinese, Spanish, and Urdu.

Part of **Language, Decoded — Expedition Tiny Aya** (Condition 4: Strictly Native Code).

---

## What this does

Contributors open the app, pick an exercise, write their solution in their native language using Legesher, run it to confirm it works, then submit. Submissions are saved to a HuggingFace dataset.

The app uses the Legesher Python API (`TokenTranslator`) to transpile native-language code to standard Python for execution — so contributors can see their code actually run in the browser.

---

## Run locally

**Prerequisites:** Python 3.10+

```bash
cd native-code-submission
pip install -r requirements.txt
python app.py
```
