# Zero-LLM Data Engine

A high-scale, production-ready backend engine for natural-language Excel/CSV/Parquet editing, built with Python and Polars.

## Local Development

To run the engine locally:

```bash
cd zero-llm-engine
pip install -r requirements.txt
uvicorn main:app --host 0.0.0.0 --port 8000 --reload
```

## Features

1. **Hybrid Parser**: Fast regex/keyword path with fallback to offline local embedding/spelling parser, local Qwen GGUF model, or Gemini cloud API.
2. **Polars Execution**: Safe and fast data frame operations with concurrency, low latency, and memory efficiency.
3. **MVCC Versioning**: Safe read/write concurrency via versioned files.
