Deferred Phase-1-completion task from the de-platform-from-GitHub
roadmap (vimwiki/diary/2026-05-03.md). Documents:
- per-host role + current services (sunken-ship, phantom-ship, vps-relay,
distant-shore, foreign-port, daniel-macbook-air, wsl);
- ZT mesh topology + ASCII overview;
- the auto-rebuild path (dm-pull-deploy push from sunken-ship → pull/
rebuild on roles.default hosts within ~15 m);
- the manual clan-cli flow, including the env -u SSH_AUTH_SOCK and
--no-check gotchas we hit in practice;
- the vps-relay reverse-proxy pattern for new public apps;
- SSH key quick-reference.
