Expose a user's artifacts through the MCP server as readable resources: each is
listed under an artifact:// URI with its mime type and read on demand as inline
text or a base64 blob, bounded by a size cap and scoped strictly to the owning
principal resolved from the request's API key, so no artifact is served across
tenants. Ship the network-level egress controls the sandbox runner needs but
cannot self-apply: a Kubernetes NetworkPolicy that allows public egress while
denying RFC1918, link-local, and cloud-metadata ranges, an optional
docker-compose egress overlay, and runner network-hardening docs.
