🛠 INDEPENDENT EXECUTION WITH just

Frontend and backend run independently or concurrently using standard just recipes:

# Display all recipes
just

# Install both backend (uv) and frontend (bun) dependencies
just install

# Run backend independently on http://localhost:8001
just backend

# Run frontend independently on http://localhost:5171 (with Vite proxy)
just frontend

# Run both backend and frontend concurrently
just dev

# Run comprehensive test suite
just test

# Execute live multi-agent query via CLI
just query q="Analyze single-point foundry bottleneck for Apple & Nvidia" tickers="AAPL NVDA"

📦 CONTAINERIZATION (DOCKER & DOCKER-COMPOSE)

Multi-stage build utilizing oven/bun to compile the React 19 single-page application and astral-sh/uv to install production Python dependencies:

# Build the production image
just docker-build

# Launch the full infrastructure stack (API + Neo4j + Qdrant + Redis)
just docker-up

# Verify health
curl -s http://localhost:8001/health | jq .
