Remote workflow guide for using Codex CLI from Android through Termux, Tailscale, SSH, and tmux while keeping code execution on an Ubuntu machine.

Early public stub for an AI-assisted fact-checking project. Listed here as a prototype idea and placeholder for a verification workflow I plan to expand.
