- Add write_readme() to the standalone bootstrap stubs (was defined in wolf-pair.sh and other services but missing here) - Only include the caddy_net network block in docker-compose.yml when ~/docker/caddy exists; otherwise docker compose up fails with "network caddy_net declared as external, but could not be found" Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01D8ckUJQtj1pH8jtAddBDZs
