BRACC Open Graph is an open-source graph infrastructure for public data intelligence.
Primary website: [bracc.org](https://bracc.org)

BRACC Open Graph is an initiative from [World Open Graph](https://worldopengraph.com).
This repository contains the full code for the public BRACC edition.

## What BRACC Represents

- Public-interest graph infrastructure for transparency work.
- Reproducible ingestion and processing for public records.
- Investigative signals with explicit methodological caution.

Data patterns from public records are signals, not legal proof.

## What Is In This Repository

- Public API (`api/`)
- ETL pipelines and downloaders (`etl/`, `scripts/`)
- Frontend explorer (`frontend/`)
- Infrastructure and schema bootstrap (`infra/`)
- Documentation, legal pack, and release gates (`docs/`, root policies)

## Architecture At A Glance

- Graph DB: Neo4j 5 Community
- Backend: FastAPI (Python 3.12+, async)
- Frontend: Vite + React 19 + TypeScript
- ETL: Python (pandas, httpx)
- Infra: Docker Compose

## Quick Start

```bash
cp .env.example .env
# set at least NEO4J_PASSWORD

make dev

export NEO4J_PASSWORD=your_password
make seed
```

- API: `http://localhost:8000/health`
- Frontend: `http://localhost:3000`
- Neo4j Browser: `http://localhost:7474`

## Repository Map

- `api/`: FastAPI app, routers, Cypher query loading
- `etl/`: pipeline definitions and ETL runtime
- `frontend/`: React application for graph exploration
- `infra/`: Neo4j initialization and compose-related infra
- `scripts/`: operational and validation scripts
- `docs/`: legal, release, and dataset documentation

## Operating Modes / Public-Safe Defaults

Use these defaults for public deployments:

- `PRODUCT_TIER=community`
- `PUBLIC_MODE=true`
- `PUBLIC_ALLOW_PERSON=false`
- `PUBLIC_ALLOW_ENTITY_LOOKUP=false`
- `PUBLIC_ALLOW_INVESTIGATIONS=false`
- `PATTERNS_ENABLED=false`
- `VITE_PUBLIC_MODE=true`
- `VITE_PATTERNS_ENABLED=false`

## Development

```bash
# dependencies
cd api && uv sync --dev
cd ../etl && uv sync --dev
cd ../frontend && npm install

# quality
make check
make neutrality
```

## API Surface
