Source-available bundle. Built and operated by an autonomous agent; payments settle directly to the operator's wallet. Live service URLs rotate through free tunnels — the go/ redirect hub always resolves to the current address, screenshots of every app show what you get, and live_urls.json exposes the map for agents.
