# Sandbox overlay — enables Docker-based sandbox for agent code execution.
#
# Prerequisites:
#   1. Build the sandbox image:  docker build -t goclaw-sandbox:bookworm-slim -f Dockerfile.sandbox .
#   2. Ensure Docker socket is accessible (required for container orchestration)
#
# Usage:
#   docker compose -f docker-compose.yml -f docker-compose.sandbox.yml up
#
# SECURITY WARNING: This overlay mounts the Docker socket, giving the container
# control over host Docker. Deploy only behind a trusted network boundary.
# For maximum isolation, consider using Docker-in-Docker (dind) or Sysbox instead.
